Facilities Maintenance & Operation Cost Optimization for Commercial Research Paper

Facilities Maintenance & Operation Cost Optimization for Commercial Buildings (this study will be applied for National Commercial Bank Buildings) - Research Paper Example The operational phase of the commercial buildings has proved to be longer compared to the construction and design phase of the project. Such a longer operational phase of the buildings makes it much cost intensive, this gives rise to evolution of high performance buildings so as to meet the sustainability goals, and energy efficiency. Facility maintenance covers all aspects of the proper operations of such commercial buildings in order to create a safe, optimal, and cost affective environment for the employees. The major divisions within the facility maintenance are operations, contracting, and maintenance, custodial, commissioning, and landscaping. The operation cost seems to be an ever increasing factor because of such maintenance facility. This research paper deals with the challenges that come in proper facility maintenance of such commercial National Bank buildings. The paper encloses a literature review on the mentioned topic and even some outline questions that are commonly as ked by the audience. The main goal of this research paper is to analyze the ways in which proper facility maintenance can be conducted in such commercial buildings with a total optimization of the operation cost. The paper deals with the various aspects of proper equipment maintenance and operation system so that it meets the goals of the facility maintenance team. The maintenance of the building equipments such as heating air conditioning, lighting etc and the hospitality for the employees incurs considerable amount of operating cost that can be only optimized through high performance building operations. Hypothesis for a research paper is set of propositions that are constructed as an explanation for some phenomena. It is rather a provisional conjecture in order to guide the investigation for a particular topic. Hypothesis is often termed a mere guess or assumption. The title for the research study is to determine

Orthoses Intervention Essay Presently, there exists a wide variety of various clinical interventions which are on the market based on personal interest, experience and skills of every clinician. Accordingly, it has become intricate for the therapist and also the patient to select the most efficient treatment for their specific problem. Since all the people who work in the health sector are involved in being answerable for providing best tools and options for the most efficient intervention, clinicians have a challenge treat their patients with the most efficient available intervention. Research hypothesis The hypothesis formulated for this research is: †¢ Orthoses are a clinically successful Podiatric Intervention Disease selected for the research background information A patient suffering from Charcot-Marie-Tooth sickness was prescribed for an ankle-foot orthoses to assist his gait. The patient was an ardent bicyclist and sought an evaluation of the impact of orthoses on his ardent bicycling activities, and also his gait. The impact of three ankle-foot orthoses on the joint angles when bicycling and walking and, ankle torque as well as production of power during walking processes as well as heart rate when bicycling were calculated. The quantitative impacts of every AFO on walking and bicycling workings are then discussed in relation to the patients inclination. Charcot-Marie-Tooth (CMT) Charcot-Marie-Tooth (CMT) sickness is a genetic neuropathic illness which results in progressive degenerate of the muscles which are distal to the knee and commonly results in gait restrictions. Ankle-foot orthoses (AFOs) devices have been used and revealed to have constructive impact on the gait of patients who are suffering from ankle muscle weakness, which includes restitution of heel strike, enhanced management of plantar flexion subsequent to foot strike, normalizing of heel rise, improved thrust for the period of push-off, stabilizing of the knee when in stance, and reduction in unusual hip and knee flexion in the process of swinging. The design of AFO might as well influence gait movement in patients who have CMT sickness. In the present study, we shall assess the effects of three different kinds of AFOs on joint angles when walking and also when bicycling, the ankle torque as well as power production when walking, and the heart rate in the course of bicycling for an individual suffering from CMT. The research also discusses the association amid these effects as well as the patients liking for AFO variety for walking as well as bicycling. Methodology Subsequent to manufacture and the patient was fitted with AFOs , the patient was later requested to use the AFO as much as he could for walking as well as bicycling, he was also asked to decide which one of the braces he had used he favored for each different activity. When a period of a bout one month elapsed during which the patient was using the devices, the gait of the patient was evaluated without AFO and also with the three different AFOs. Another period of two weeks elapsed and the patients bicycling activity was assessed without the AFO at first and then with the three different AFOs afterwards. Results Gait speed The resulted indicated that, the pace of walking on the ground was quicker when using the no-AFO state (1. 09 m/s), then the solid ankle AFO state followed with (1. 04 m/s), and this was followed by the posterior trim AFOs and the prefabricated AFO (1. 01 m/s). The usual self-chosen adult walking pace ranges between 1. 33 m/s and 1. 51 m/s, (Pierson-Carey et al, 1997) so the patient’s walking pace was slower compared to the normal pace. The variations in pace amongst the three AFO states as well as the no-brace state are minute, however using the AFOs might have reduced the patients walking pace a little. Joint angles The key distinction in joint angles happened at the joint of the ankle during swing point with the utilization of solid ankle as well as posterior trim AFOs. It was observed that the prefabricated AFO had slight consequence on ankle joint angles when contrasted with the no-AFO state. During a foot strike where an AFO was not used and when the prefabricated AFO was used the results were that the ankle of the patient was plantar flexed. In addition, there was just a small upward angulation position of the foot comparative to the floor (Table1). But, when posterior trim AFO as well as solid ankle AFO were used, the ankle joint of the patient was observed to b in dorsiflexion at point of the foot strike with an additional normal heel strike. Ankle torque A person’s internal ankle torque production is due to a different muscle activity in the body inactive broadening of tissue, as well as restrictions due to the AFO and also the shoe. Contrasted with usual gait, every state resulted in a lot lesser torque production for dorsiflexion as well as plantar flexion (Figure 1). It was observed that, the solid ankle and posterior trim AFO conditions both resulted in dorsiflexion torques of longer period following foot strike when contrasted with the no-AFO as well as the prefabricated AFO states produced results which were inline with the ankle joint angle outcomes, which revealed a lot of heel strike with solid ankle as well as posterior trim AFO. Discussion It is commonly accepted that putting on ankle foot orthosis (AFO) can result in a positive impact on the gait in patient suffering from hemiplegia. The orthoses assist in a number of functions in ambulation which includes controlling dorsiflexion and also plantarlexion in stance as well as swing stages of gait. In addition, AFOs are believed to steady the ankle in ankle’s transverse and frontal planes in times of gait activities and balance. Pierson-Carey, et al (1997) however, points out that, traditionally, a normal metal (Bicaal) AFOs have in the past been researched to additional asses clinical observation on joint stability among patients with Charcot-Marie-Tooth who use these devices Lehmann, et al (1986) observes that, in the process of the mid stance as well as propulsion stages of gait of the patient, the no-AFO as well as posterior trim AFO states led in lesser values of plantar flexion torque being produced when compared to solid ankle AFO or even the prefabricated AFO states. When in the mid stance point of gait of the patient, the plantar flexors usually offer restrictions to forward movement of the tibia, while the foot of the patient remains rooted on the ground. In the propulsion stage the plantar flexors usually operate to bring fourth heel rise as well as plantar flexion of the patient. Solid ankle AFO as well as the prefabricated AFO were observed to be more efficient in offering plantar flexion torque (restriction to dorsiflexion) when in these stages. On the while the posterior trim AFO was formulated to give restriction to plantar flexion and not resist dorsiflexion, as a result it was not as efficient to provide to plantar flexion torque in these stages. Conclusions This research has concluded that, using the posterior trim as well as solid ankle AFOs when walking reduced the extreme hip and knee flexion of an individual. It also reduces the ankle plantar flexion in the process of swinging. However, there were no significant modifications during stance period. The patient in the case study was conscious of these encouraging transformations in his gait when using the AFOs. Nevertheless these transformations were not important enough to result in him using AFOs in every circumstance, and as such the patient used them merely in circumstances in when the look of his own gait was imperative to him only. When the patient indeed used AFOs for walking, the patient favored the posterior trim AFO compared to the solid ankle AFO since it fit him better than the posterior trim into his dress shoes. When cycling his bicycle, usage of the different AFOs reduced the inclination toward extreme dorsiflexion when performing the downward stroke and the solid ankle AFO was observed as the most efficient. Consequently the patient favored to using solid ankle AFO when cycling, however the patient did not detect any variation in the cycling speed on his normal road bicycle when using solid ankle AFO. However as Lehmann (1993) notes not any of the AFOs attested to be better in walking process or cycling activities, as such the patient favored to using dissimilar AFOs for these activities. More research would be required integrating diverse AFO designs, equipment, and positions, to establish if it is probable to formulate one particular AFO which optimizes the patient’s walking as well as bicycling effectiveness. Extra outcome procedures, which include oxygen expenditure and ankle power assessments when cycling, might assist to better discern amongst variations in performance which are attributed to the using of diverse AFOs.

Mortality Regimes And Longevity Risk Health And Social Care Essay

This paper explores the presence of governments in mortality kineticss and assesses their deductions for length of service hazard direction. Our attack extends the Poisson log bilinear arrested development developed by Brouhn et Al. by capturing the time-varying mortality constituent with a Markov regime-switching theoretical account. The theoretical account is so applied to Gallic mortality informations sets from 1947 to 2007. Our analysis reveals that one government is characterized by high volatility and is active during the 20 old ages after the Second World War. The 2nd government corresponds to a province of low volatility and captures length of service betterments observed during the recent period. A Monte Carlo simulation is so used to look into the impact of mortality governments for the hazard direction of life rente portfolios. Simulation reveals that the initial distribution of a mortality government affects well the solvency degree of portfolio and the capital demands, c orroborating the importance of taking into history mortality regimes for the direction of life rente portfolios. Keywords: Life rente, Mortality Projection, Regime-switching Models JEL Classification: C32, G22, G23 1. Introduction Life anticipation everyplace has increased well over the last century. In France, mortality has declined steeply, as older people live longer. Life anticipation at birth for males has passed from 45 old ages in 1900 to 81 old ages in 2000. This phenomenon is seen as good intelligence for persons and as a significant societal accomplishment. However, it poses new challenges for the policy shapers, private pension directors and other suppliers of life rentes, where the consequence of life anticipation betterments on the solvency of pension systems is a concern ( Macdonald et al. , 1998 ) . As underlined by Marocco and Pitacco ( 1998 ) , length of service hazard, that is, the uncertainness sing the future development of mortality and life anticipation results, affects the pricing and reserving of life rente merchandises well. Indeed, establishments supplying life rentes run the hazard that the existent value of projects exceeds their outlooks, taking to state of affairss of bankruptcy, when establishments can non pay the promised sum to endorsers. The computation of expected present values therefore requires an appropriate mortality projection that avoids underestimating future duties. In 1992, Lee and Carter proposed a simple theoretical account that specifies mortality rate alteration as a map of a individual clip index. The method describes the mortality rate as the amount of an age-specific constituent independent of clip and a bilinear term that is the merchandise of a time-varying parametric quantity vector stand foring the development of mortality over clip and an age-specific vector of parametric quantities reflecting how each age is impacted by the development of mortality. The estimation of the time-varying parametric quantity is so modeled and forecast as a stochastic time-series utilizing the Box-Jenkins method. The forecast mortality rate is so obtained by uniting the prognosis time-varying mortality constituent obtained by an ARIMA theoretical account, with the estimated parametric quantities relative to age effects. However, the usage of an ARIMA theoretical account to depict the behaviour of mortality over clip appears unrealistic. As Sweeting ( 2010 ) underscores, mortality nowadayss sudden alterations in tendencies, proposing the presence of a non-linear construction. Furthermore, the mortality procedure exhibits non-Gaussian belongingss such as fat dress suits, heteroscedasticity, and lopsidedness. In visible radiation of these facts, we propose to capture the time-varying mortality constituent obtained by a Poisson log bilinear theoretical account appraisal, with a Markov exchanging theoretical account. Markov exchanging theoretical accounts were introduced by Goldfeld and Quandt ( 1973 ) and became popular after the seminal paper of Hamilton ( 1989 ) . In finance and economic sciences, regime-switching theoretical accounts have received turning attending. They are capable of capturing complex non-linear kineticss, including sudden alterations in the behaviour of clip series, and complicated signifiers of heteroscedasticity, fat dress suits, and skews. They are notably used to capture the kineticss of GDP ( Hamilton, 1989 ) , plus monetary values ( Longin and Solnik, 2001 ) or involvement rates that exhibit non-Gaussian belongingss ( Ang and Bekaert, 1998 ) . Ang and Timmermann ( 2011 ) supply a good study of the assorted applications of Markov exchanging theoretical accounts in economic sciences and finance. In actuarial scientific disciplines, government shift has been largely focused on the pricing of fiscal merchandises ( Hardy, 2001 ; Bollen, 1998 ) . To our cognition, merely M ilidonis et Al. ( 2011 ) have explored the usage of Markov regime-switching theoretical accounts to capture mortality kineticss. They apply this type of theoretical account to US informations from 1921 to 2005 and demo that mortality is characterized by a two-regime shift theoretical account. However, their work brushs an obvious unfavorable judgment: the designation of mortality governments could be merely due to the presence of the two universe wars in their sample. In this paper, we explore the inquiry whether mortality governments are discernable in Gallic informations from 1947 to 2007. Using an information standard attack, we find that Gallic mortality is characterized by two distinguishable governments. One government refers to a strong uncertainness province, matching to length of service conditions observed during the decennary following the Second World War. The 2nd province is related to the low volatility of length of service betterments observed during the last 30 old ages. The cardinal invention of our paper is the probe of the influence of mortality governments on length of service hazard. Using Monte Carlo simulation, we derive a conditional distribution of prospective life tabular arraies, which are so used in order to mensurate the influence of mortality governments on life rente portfolio hazard. It appears that the active distribution of a mortality government affects well the projection of mortality, but besides the uncertainness that comes from this projection. That connexion is peculiarly of import for statisticians, who must find the sum of money required to pay pensions, every bit good as the safety lading used to cover the uncertainness relation to the betterment in life anticipation. The paper is organized as follow. Section 2 nowadayss notations, premises, and informations. Section 3 provides a elaborate presentation of the methodological analysis associating to mortality projection theoretical accounts. Section 4 presents the appraisal consequences. In subdivision 5, a cash-flow simulation of a portfolio of life rentes measures the chief deductions of a mortality government on length of service hazard and capital demands. Section 6 concludes the paper. 2. Notations, Assumptions, and Datas 2.1. Notation Mortality is studied in two dimensions: age, and calendar clip. We shall utilize so following notation: represents the staying life-time of an single elderly on January 1 of twelvemonth. is the chance that an single elderly in twelvemonth dies before making age. is the chance that an single aged survives during the twelvemonth and reaches age ; note. is the cardinal mortality rate at age during the clip. is the exposure to hazard at age during twelvemonth. It represents the entire clip lived by people aged during the twelvemonth. represents the figure of deceases at age during the clip, from an exposure to hazard. represents the figure of persons aged in life during the twelvemonth. is the expected staying life-time of single aged in the clip. is the monetary value of the net present value of a life rente sold to an single elderly in twelvemonth. 2.2. Premises The cardinal mortality rate is supposed changeless within two sets to and to. For any given whole number and a day of the month, we so obtain: ( 1 ) The premise of a changeless mortality cardinal rate implies that for an single elderly in twelvemonth that: ( 2 ) Finally, two measures of involvement mostly used by demographists and statisticians are introduced. Life anticipation is a classical step sum uping the development of the mortality over the clip: ( 3 ) The computation is based on the survival chances from age to the ultimate age aa‚ ¬ † The maximal age considered depends on the pick of life table closings.[ 1 ]As the endurance chances are non available after clip, they must be extrapolated from a projection theoretical account. The life rente refers to the net present value of future payments sold to an single elderly in twelvemonth: ( 4 ) where is the price reduction factor that we suppose changeless over clip.[ 2 ] 3.2. Datas For this survey, male and female Gallic mortality informations have been taken from the Human Mortality database.[ 3 ]The informations consist of the cardinal mortality rate, the exposure to hazard, and the figure of deceases between two ages. It was desirable to utilize merely informations from 1947 through 2007. The period before 1947 has been ignored to avoid the mortality dazes associated with the first and 2nd universe wars. We consider merely the age scope between 60 and 98 old ages. Age classes younger than 60 twelvemonth are ignored, since the aims of this survey focal point on length of service hazard jobs. The information, at older age ( over 98 old ages ) have besides been excluded due to the little figure of subsisters. Mortality at older ages will be however generated from a log quadratic map ( inside informations will be given in subdivision 3.5 ) . Figures 1-a and 1-b show the development of Gallic mortality during this period. A net decrease in mortality is observed f or both work forces and adult females, in peculiar at advanced ages. [ Figure 1 about here. ] 3. Methodology 3.1. A Poisson log bilinear theoretical account Following the attack introduces by Brouhns et Al. ( 2002b ) , the figure of deceases is captured by a Poisson distribution: ( 1 ) where is the force of mortality, designed as a log bilinear construction. The parametric quantities have the same reading as in the traditional Lee Carter theoretical account. The measures, and are specific age parametric quantities, is a time-varying parametric quantity stand foring the development of mortality over the clip. Again, is the exposure to hazard.[ 4 ]. The merchandise of and is the strength parametric quantity of the Poisson distribution ( ) . ItHe represents the expected figure of deceases during the twelvemonth. Finally, as in the Lee-Carter theoretical account, we impose restraints on parametric quantities and to guarantee theoretical account designation: ( 2 ) One advantage of the Poisson log bilinear theoretical account over the Lee Carter theoretical account is that appraisal is realized by maximising the likeliness, alternatively of a remarkable value decomposition ( SVD ) . Consequently, there is no demand to hold a complete rectangular matrix of informations to gauge parametric quantities. Furthermore, a Poisson log bilinear gives straight the figure of deceases whereasile the Lee Carter theoretical account gives merely an appraisal of decease rates. 3.2. Model appraisal The log bilinear Poisson theoretical account is estimated by maximising the log-likelihood: ( 3 ) The presence of the bilinear term does non let one to using classical Poisson arrested development. To avoid this job, the appraisal is resolved by the simple Newton method, ( Goodman, ( 1979 ) . The rule consists into updatinge the individual set of parametric quantities whilein repairing the other parametric quantity at their current values: ( 4 ) The lLog bilinear Poisson theoretical account comprisesaccounts three different sets of parametric quantities, the, the, and the vector vector. The updating algorithm is organized as follow: : ( 5 ) ( 6 ) ( 7 ) wWhere is the expected figure of deceases occuroccurringed each twelvemonth. [ ? ] propose to initialise the algorithm with get downing values, , and. At the terminal of the updating measure, the theoretical account designation is non ensured. To esteem the restraint suggested by Lee and Carter ( 1992 ) , the theoretical account must be reparametrized as follows: ( 8 ) ( 9 ) ( 10 ) wWhereith and is the mean of footings. Contrary to the Lee Carter attack, there is no demand to readapt the procedure the kappa as own map of the figure of deceases. 3.3. Modeling the time- factor under a Markov shift theoretical account As underlined by Sweeting ( 2010 ) emphasizes in defence of the pick of government exchanging theoretical accounts to capture dynamic mortality, the mortality procedure exhibits a sudden interruption during the last century, supporting the pick of government exchanging theoretical accounts to capture dynamic mortality. Following this determination, we model the procedure with a regime-switching theoretical account. The procedure exhibits a non- stationarity. The application of a first- difference filter removes the tendency constituent from the series and gives a stationary procedure toon which we can use our theoretical account. Let be the clip series, obtained from the first differenced. We suppose that is modeled as a regime- shift procedure: ( 11 ) ( 12 ) andWhere and are, severally, the intercept and the autoregressive coefficients comparative to each province. The term represents the vector of conditional remainders. The term is the conditionnal residuary term, usually distributed with a average equal to zero and a regime-dependent criterion divergence. The theoretical account described here is really general and allows intercepts, autoregressive footings, and covariances to change across provinces. When presuming one government is assumed, the theoretical account becomes a simple AR ( cubic decimeter ) theoretical account. Governments passages are governed by a procedure that satisfies the undermentioned Markov concatenation belongingss: ( 13 ) Hence, each government is the realisation of a first- order Markov concatenation with changeless passage chances. The province kineticss are unseen and must be inferred straight from the discernible variable. The passage chances are represented in the passage matrix: ( 14 ) Each component of the matrix P must fulfill the undermentioned conditions: ( 15 ) The choice of figure of governments is a current job infrom regime- exchanging theoretical account researchs. To find the figure of governments, we adopted the information standard for theoretical account choice. This method offers good consequences and is easy to transport out ( Psaradakis and Spagnolo, ( 2006 ) . Refering the pick of information standard, we preferprefer to used the MSC standard that has beenwas developed specifically for regime- shift theoretical accounts, ( Smith et al. , ( 2006 ) . However, the AIC standard is besides reported. To gauge the theoretical account, we use an iterative numerical process based on the Expected Maximization ( ) algorithm developed by Dempster et Al. ( 1977 ) . The process is an optimisation technique designed for theoretical accounts where the ascertained clip series depends on an unobservable stochastic variable, such as in Markov exchanging theoretical accounts. The get downing values required to initialise the algorithm are obtained by using the K-means method ( MacQueen et al. , ( 1967 ) . 3.4. Prospective life tabular arraies and assurance intervals In prediction, an indispensable inquiry concerns the degree of uncertainness degree relation to the forecasted measures, such as mortality rate or life anticipations. A good cognition of the distribution and assurance intervals of forecasted measures aAlso, he appears indispensable to hold a good cognition of distribution or assurance intervals of forecasted measures. Unfortunately, in theour instance we are analyzing, we can non deduce an analytical look for the distribution or assurance intervals. This is due to facts that, the building of prospective life tabular arraies needfully involvesrequires uniting two kinds oftype mistakes. The first mistake arises from the appraisal of, , and. The 2nd mistake comes from the projection of, because of the parametric quantities of regime-s shift theoretical accounts are themselves random variables. Furthermore, the involvement measures of involvement, such as life anticipation, are non- additive complex maps of Poisson parametric quantities and regime- shift parametric quantities ; , this poses an extra complication. To get the better of these jobs, a Monte Carlo simulation process is used to come close the distribution of involvement pertinent measures such as mortality rate, life anticipation, and life rente. The simulation is organized as follows. First, we generate MM samples of, , and, where m is the index relation to the m-th simulations. Let be the m-thmth fake parametric quantity sets composed of, , and. Under regularity premises, asymptotic belongingss of maximal likeliness calculators ( MLE ) warrants that is generated followerss a multivariate normal distribution ( MND ) with average vector, , , and covariance matrix given by the opposite of the Fisher information mMatrix. From the fake series, we estimate MM government exchanging theoretical accounts and obtain MM parametric quantity sets denoted. Each set is composed of, , , , and elements of the associated passage chances matrix associated. The parametric quantity sets are so used to bring forth MM projections of, denoted. Note that under regime- shift scenes, the predicted values do notnaa‚ ¬a„?t depend merely on estimated parametric quantity sets as in the instance of additive theoretical accounts. They are besides affected by the initial distribution of governments, denoted by the vector of chances selected as exogenic.[ 5 ]. In a two- government theoretical account without autoregressive footings, the fake values are given by ( 16 ) wWhere is a Markov concatenation generated from the initial province vector and chances passage matrix. The map is an index map equal to 1 if the procedure province is in the government. The projection is so derived from. The fake parametric quantity sets, , , and are eventually combined to build MM prospective life tabular arraies, denoted ( 17 ) wWhere m is the index relation to the mt-th simulations, the initial distribution of mortality governments, and the day of the month from which the values are projected. 3.5. Polynomial smoothing of older ages and shutting of life tabular array closings The computation of the mortality rate in old ageat older ages, poses significant jobs to demographists and statisticians. Indeed, mortality informations for older agesat older ages are frequently characterized by the presence of outlier informations. Wilmoth ( 1995 ) identifies two chief grounds. First, big random fluctuations are comparative to the little figure of single who survive to older age. Second, that is due to inaccuracies exist in the coverage of age in nose count. These inaccuracies causeprovide to cumulative deformation of heaping on ages by a multiple of five or ten. A natural solution to get the better of at this job is to smooth the mortality informations get downing from a specific age, for illustration, 80 old ages. Wilmoth ( 1993 ) established that the curve of the log mortality rate has a concave signifier inat older age. From On the footing of these findings, Denuit and Goderniaux ( 2005 ) proposed seting the log mortality by least squaresss square with a log-qu adratic map: ( 1 ) Capable to the Under contraintsconstraints: ( 2 ) wWhere corresponds to the first derived function of. The restraints and correspond to conditions of the shutting of the life tabular array. The first restraint fixes the upper bound of lifetime, while the 2nd assumessupposes that the incline of the log mortality curve become zeronull at maximal age. CIn uniting these equations, we obtain: ( 3 ) To find the age from which it is necessary to get downing log quadratic parameterization, we refer to [ ? ] in which it is the finding ofchoose to find so as to in maximising the coefficient of finding. In Our instance, = . A simple geometric mean is used to smooth the mortality rate around to this age. 4. An application to Gallic population mortality 4.1. Appraisal of Poisson log bilinear theoretical account The log bilinear Poisson theoretical account, presented in subdivision 3.1, is applied to French data sets. Figure 3 plots the value of, , and obtained from the appraisal. As in the classical Lee Carter theoretical account, may be interpreted as the norm of. The curve is monotonically increasing, relatinged to higher mortality with age. As expected, adult females present values that are ever lower than those of work forces, reflecting a highersuperior life anticipation. Figure 2-b exhibits the form. The curve increases somewhat until age 75 old ages, and so diminutions. The values remain positive, bespeaking a decrease of mortality for all ages. The term is plotted ion figure 2-c. This term reflects the lessening of mortality over the clip.[ 6 ]. As expected, it exhibits a regular bettering tendency, slightlygently more of import for adult females than work forces. After 2007, the calculationus of mortality rates requires knowledge ofto know the future values of. For this, we projectate future values from the regime- shift theoretical account as described in subdivision 3.3. Since the augmented Dickey Fuller trial, reported in table 1, confirmsAs that the series is non-stationary ( The augmentedDickey Fuller trial are reported in table 1 confirms it ) , , the appraisal and projection are based on the differenced series, viz. ) , whichthat is stationary. The tabular array besides reports the descriptive statistics of. He appearsIt emerges that exhibits an surplus of lopsidedness and kurtosis, in peculiar in the instance of notably by adult females. A Jarque-Bera trials is besides reported to analyze whethertest if follows a G aussian distribution. It is clearHe appears clearly that the behaviour is non-t Gaussian for both work forces and adult females. This confirms the, corroborating the involvement ofto patterning the time- varying constituent with a regime- shift theoretical account. [ Table 1 about here. ] [ Figure 2 about here. ] 4.2. Forecasting the mortality with government exchanging The kineticss of areis captured with a regime- shift theoretical account. To choose goods characteristics of the theoretical account, an information standard attack has been adopted. A big scope of specifications washas been tested byin augmenting bit by bit the figure of governments of governments and the figure of slowdown of slowdowns. The table 2 nowadayss merely the consequences for the instance and.[ 7 ]. – regime- exchanging theoretical account with regime-dependent impetus and regime-dependent criterion divergence theoretical account performs better than a single- government theoretical account for both work forces and adult females. the MSIH ( 2 ) theoretical account and geometric Brownian gesture ( GBM ) are reported ion tabular array 2. The two identified governments in government the shift theoretical accounts are easy explainable. The first government corresponds to a high uncertainness province of mortality development, while the 2nd is characterized by a low volatility of mortality. Indeed, the standard divergence is higher in the government 1 ( 3.64 for work forces and 6.25 for adult females ) than in the government 2 ( 0.43 for work forces and 0.85 for adult females ) . CThe comparing with the additive theoretical account reveals that the uncertainyuncertainty may be twice every bit high compared comparative to classical ARIMA appraisal. Our consequences uncover differences harmonizing to sexthe sexe. As expected, the drift term is more higher for adult females than for work forces, reflecting the current difference of life anticipation observed in mortality informations. However, the consequences besides indicate that the mortality development is more unsure 40 by adult females than forby work forces. Finally, the fact that the impetuss are non statistically significantly different from nothing in government 1, suggests that government 1 corresponds instead to a government of decelerating down inof anticipation life betterment. [ Table 3 about here. ] s after 1965. A similar information mutant is observed for adult females, excepted that the switch appears more Oklahomans, from 1960. Finally, a new switch of governments is captured in 2003 both for both work forces and adult females. This is explained by the heat wave that swept acrossof heat occurred in Europe, during the summer of 2003, which increased has caused an overmortality amongst frailer older peopleby older people the more frail. At the terminal of table 2, we report the ergodic chances and continuance steps relative to each mortality government. For work forces, we find that the chances to be in a government 1 or in a government 2 are comparatively closed. In footings of continuance, the governments are extremely relentless. For work forces and adult females, the government lastsgoes on around 20 old ages. The mortality regimes seem so sufficiently, adequate persistent to impact durably the life anticipation of insurance companies, and the degree of liabilities, which insurers consider. [ Figure 3 about here. ] 4.3. A distribution of pProspective life tabular arraies As explained in the subdivision 3.4, a Monte Carlo simulation is used to bring forth 5000 samples of the original parametric quantities the simulation are non reported here for deficiency of infinite, but are available on demand. The assurance intervals derived from the sSimulations, give us a good position of the uncertainness relation to the log bilinear Poisson appraisal. From the fake parametric quantities for the regime- shift parametric quantities theoretical account is so obtained.s. The quantile s the general degree of uncertainness relation to mortality projection. [ Table 4 about here. ] tabular arraies are so derived from the fake parametric quantities ( wWhere – shift scenes, the prediction of mortality rates depends on the distribution of the mortality government at the day of the month of projection, namelyFor the interest of simplificationTo interest of simplify, we assume that the active government in s to has two possible instances, viz. pertinent measures will be computed as maps of both distributions. A last measure is required to finalise the life tabular arraies. As explained in the subdivision 3.4, we apply aA log- quadratic map to smooth mortality at older ages and shut the tabular arraies as discussed in [ ? ] – quadratic theoretical account is fixed at 80 old ages. Figure 4 gives an illustration of smoothed and closed life tabular arraies, including projections out tountil 2050 and presuming an initial distribution tabular arraies, we derive two other involvement measures of involvement, viz. the distribution of life anticipation, and the distribution of a life rente ( i.e. , a net individual premium life rente ) . The life anticipation and the net individual premium are investigated utilizing the longitudinal ( cohort ) attack ( cohort attack ) . This method differs from the transversal attack in the sense thatwhere the development of mortality is non investigated merely in footings of calendar times, but besides takes into history the twelvemonth of individualsaa‚ ¬a„? birthdays. Under the longitudinal attack, life anticipation and the life rente are given by – twelvemonth endurance probabilities the mortality rate In the computation of the life rente, we assume that the price reduction factor the short rate observed over the sample period ( 1947-2007 ) , equal to 4 % . It appears that the mortality government affects well the distribution of life anticipation and life rente well. Harmonizing to the active government at the projection day of the month, the distributions function exhibits different forms, bespeaking that the mortality government affects the jutting values, but besides the uncertainness relation to projections. If we consider the instance where the government 1 is active at the projection day of the month, the life anticipation distribution nowadayss fat dress suits compared to the Gaussian instance, bespeaking that the classical projection theoretical account ( ARIMA theoretical account ) may underestimatea possible underestimate of life anticipation betterments by the classical projection theoretical account ( ARIMA theoretical account ) . That fact is peculiarly of import for statisticians, whothat decide theto sums of money required to fund the payment of the pensions, or the safety border required to hedgethe coverage of the uncertainness relatingve to the betterment inof life anticipation. Harmonizing to the new European solvency system ( Solvency II ) , the solvency capital demand ( SCR ) must vouch that Thea ruin chance of ruin is below toless than iesy supplying life rentes run the hazard that the choosen safety burden is non plenty to vouch the payment of pensions. , and endorsers. First, how do mortality governments affect the hazard of life rente portfolios? Second, what is the economic cost of disregarding governments? To reply to theseis two inquiries, we follow [ ? ] a life rente portfolio of life rentes under different mortality regime- exchanging scenes. 5.1. Methodology See a portfolio composed of of age 65 old ages, supplying a unit capital at the terminal of each twelvemonth. At the beginning of the distribution stage, in 2007, the company which manages the life rentes portfolio defines a measure of money ( i.e. , net individual premiums ) , matching to the value nowadays of the expected cost of paying a decease benefit. Each twelvemonth, one unit of money is distributed to each populating single. The portion of non- distributed militias is reinvested, bring forthing a returnthe last single. Let rReserve available at the get downing day of the month. the portfolio. The figure of deceases a Ppoisson distribution withof strength parametric quantity the one- twelvemonth subsister chances from s during 2007 is so simulated from the Poisson distribution utilizing: the old subdivision, the figure of deceases depends straight on the initial active government. So, sSimulations are conducted for each initial mortality province. The figure of subsisters at the beginning of following twelvemonth is given by: , the initial modesty of rentes, the rReserve is so equal to: vanishes wholly vanished, for the last single. We besides assume that the rate of return on the modesty the price reduction rate ( 4 % ) . At the beginning of the distribution stage, we assume that the company gets an sum, the net individual premiums ) , which is used to pay the pensions until the decease of the last single. We investigate five three calculating methods for calculating of this sum: : Pure premium under cross position. We consider the instance where the net individual premium is merely computed from mortality informations from 2007 ( without any mortality projection ) . Regime-dependent pure premium under longitudinal position. The mortality rates are projected utilizing a Markov exchanging theoretical account, and used to monetary value life annuitiesy as described in subdivision 3.4. Note that under the Markov shift model, the net individual premium is a regime-dependent measure, which differs harmonizing to the initial active government. Regime-dependent pure premium + safety border under longitudinal position. Finally, we investigated the instance where a safety border is added to the conditional expected premium computed from longitudinal attack. The net individual premiums are defined, by bear downing the 90 % , 95 % , and 99.5 % percentile of life rente denseness, as described in old subdivision. For each value of net individual premiums, we compute five hazard indexs, mensurating how mortality projection affects the life rentes portfolio, viz. : tThe pProbability of ruin which is, i.e. , the chance that the net individual premium defined in 2007 does notnaa‚ ¬a„?t suffice to pay all the promised payments. The chance is computed byin sing a rate of return on the modesty equal to the price reduction rate. tThe clip until ruin, i.e. , means the mean figure of twelvemonth elapsed before ruin, given that the ruin occurs. tThe average loss, i.e. , corresponds to the norm of the shortages registered for the twelvemonth whenre the ruin occurs. tThe average figure of staying cContracts, i.e. , contracts staying in the twelvemonth whenre the ruin occurs. tThe fudging involvement rate, i.e. , which is the involvement rate on the modesty needed to guarantee a entire hedge of length of service hazard ( in other wordsi.e. , a chance of ruin thatwhich is niull ) . 5.2. Consequences of Cash flow Simulation Tables 5 and 6 resume the chief consequences of the simulations. Hazard steps are computed for each value of a net individual premium. Tables 5-a and 6-a show the simulation consequences when the initial province is the government 1, while tabular arraies 5-b and 6-b refer to the state of affairs where the government 2 is active. Note fFirst that, sSimulations highlights the importance of mortality projections. The net individual premiums computed on the footing of the transversal method leads to the bankruptcy in about of 80 % of fake instances. We find that about one 3rd of contracts are non fulfilledsatisfied and the average loss at the minute of ruin corresponds to more thanof 20 % of the nominal sum. [ Table 5 about here. ] a logical decrease oflogically diminishing the chance of ruin. However, ithe appears to be necessary to include a safety burden, since bear downing the pure premiums on the footing of the longitudinal method consequences into the negative hard currency flow in 50 % of fake instances. The last row of each tabular array considers the instance where the Ssolvency Ccapital Rrequirement is applied, ( that is, intending that the safety lading allow to coverensures coverage of 99.5 % of the fake scenarios ) . As expected, the chance of ruin, the average loss, mean and the figure of unfulfilledsatisfying contracts so decreases so substantiallysignificantly. An indispensable determination of our research concerns the fact that the mortality province active at the beginning of the distribution stage affects well the hazard of life rente portfolios well. For a similar degree of hazard ( i.e. , ruin chance of ruin ) , we note big differences in the pure premium harmonizing to which ofwhen the government 1 or regime 2 is active or when the government 2 is active. The safety burden, which is the extra sum of modesty required to restrict the ruin chance, is besides affected. If we consider the degree of ruin defined harmonizing to Ssolvency II2, ithe appears that the safety burden is twice as higher when the government 1 is active, reflecting the strong uncertainness comparative toin mortality development inrelative to this province. It is besides interesting to observe that mortality governments affects the day of the month of bankruptcy, the degree of average loss or the figure of unfulfilledsatisfying contracts. All these steps are deterior ated when the government 1 is active at the beginning of the distribution stage. [ Table 6 about here. ] Simulations performed on the female informations confirm these consequences. It appears clearly that the initial province affects the hazard of the portfolio. However, the consequences highlight differences harmonizing to the gender of endorsers. The day of the month of bankruptcy occurs subsequently on norm more recently for adult females than for work forces, while the average loss is higher for adult females than for work forces. Similarly, the figure of staying contracts at the bankruptcy day of the month is higher for adult females than for work forces. So far, we established that the existencepresence of government shift in the distribution of mortality could impact the hazard of life rente portfolios well. This grounds does non connote, nevertheless, that companiesy thatwhich manages the life rente portfolios are is needfully better off if they accountby accounting for governments in the mortality distribution. So, we assess hence the economic cost of governments. We undertake this analysisdo it by comparing the hazard step under the regime- shift theoretical account of mortality to the riskat presuming the pension director is constrainedt to take a net individual premium under the premise that mortality development follows a simple geometric Brownian gesture. Table 6 presents the brinies consequences. Columns 1 and 3 study the chance of ruin when the pension director is constrainedt to disregard governments. We find that disregarding governments increases well the hazard of bankruptcy for a starting government of high volatility ( province 1 ) . That suggests a possible underestimate of length of service hazard by the classical projection theoretical account.[ 8 ]. For the instance where the pension director triesy to esteem the Ssolvency Ccapital Rrequirement ( last row of each tabular array ) , disregarding high volatility governments is tantamount to doublinge the chance of ruin for male endorsers ( from 0.5 % to 1.1 % ) , and to multiplying it by 5 for female endorsers ( from 0.5 % to 2.4 % ) . A 2nd manner to quantify the effects relative to disregarding the governments is to calculate the fluctuation of safety burden, fulfilling the ruin chance mark. In other word, what is the sum of safety burden that a pension director constrained tot disregarding governments must add in order for that the ruin chance of his portfolio to match to the true mark. The per centums are reported in the columns 2 and 4 of table 6. For statisticians and pension directors, an highly relevantinteresting value for the safety burden is that necessaryrelative to esteem the mark defined by solvency 2Solvency II. We find that disregarding a high volatility government is tantamount to underestimatinge the safety lading byfrom 13 % for work forces and byfrom 27 % for adult females, compared to the degrees predicted by the classical ARIMA theoretical account. These consequences confirms therefore the importance of taking accounting mortality regimes into history for the direction of theportfolios of life rentes life rente portfolio. [ Table 7 about here. ] 62. Decision This paper explores the presence being of governments in mortality kineticss and measures the deductions for a portfolios of life annuitiesy. This is achievedWe do it by capturing the kineticss of time- changing mortality constituents obtained by a Poisson log bilinear theoretical account appraisal with a Markov exchanging theoretical account. The pick of a Markov exchanging theoretical account is motivated by the fact that time- changing constituents exhibits sudden alterations of tendencies and exhibitpresents lopsidedness and fat dress suits, bespeaking a non- Gaussian distribution. The theoretical account is applied to the Gallic mortality informations from 1947 to 2007. The appraisals reveal the existencepresence of two governments in mortality kineticss. The first government is characterized by a highstrong volatility, and is operativeactive during the 20 old ages after the Ssecond Wworld War ; t. The 2nd identified government corresponds to a province of low volatility, and ca ptures the recent development of mortality. Using Monte Carlo simulation, we derive a conditional distribution of prospective life tabular arraies, and utilize them in order to look into the influence of mortality governments on the hazard of life rente portfolios. Simulations show that mortality governments affect well the monetary value of life rente merchandises and the safety burden required to cover the uncertainness relation to betterments in life anticipation life betterment. The fact of ignoringIgnorance of these governments result Immigration and Naturalization Services to underestimate of e the true hazard of bankruptcy. Harmonizing to our computationsing, disregarding a high volatility mortality government is tantamount to bearinghave a chance of ruin toof 1.1 % for work forces and to 2.5 % for adult females. However, Solvency II while solvency 2 regulations recommend that this chance ishould be smaller than 0.5 % . Our consequences argue in favour of mortality projections under government exchanging instead under ARIMA theoretical accounts. Indeed, mortality governments affect clearly the rating of liabilities, and disregarding governments consequences in to underestimation ofe the length of service hazard or mortality hazard. Sing In position of the prudential attack required by the rating of liabilities, the incorporation ofhe appears necessary of accounting mortality governments in thefor direction of the life rente portfolios appears necessary, and it seems sensible to recommend that the least favourable government should be used toeventually to monetary value the life annuitiesy or decease insurance merchandises utilizing the government the most unfavourable.

Lateral thinking

Lateral thinking is a term coined by Edward de Bono, a Maltese psychologist, physician, and writer, although it may have been an idea whose time was ready. De Bono defines Lateral Thinking as methods of thinking concerned with changing concepts and perception. He invented the term ‘lateral thinking'. It was first written up in a book called â€Å"The Use of Lateral Thinking†. (1967) It is similar to creative thinking. It is also seeking to solve problems by unorthodox or apparently illogical methods. â€Å"A set of systematic techniques used for changing concepts and perceptions and generating new ones†, (de Bono, 1967) â€Å"Exploring multiple possibilities and approaches instead of pursuing a single approach.† (Infinite Innovations, 1997)There are numerous ways of defining lateral thinking, ranging from the illustrative to the technical. First, â€Å"You cannot dig a hole in a different place by digging the same hole deeper† (de Bono, 1997a) This m eans that trying harder in the same direction may not be as useful as changing direction. Effort in the same direction (approach) will not necessarily succeed. Second, â€Å"Lateral Thinking is for changing concepts and perceptions† (de Bono, 1997b) With logic you start out with certain ingredients just as in playing chess you start out with given pieces. But what are those pieces? In most real life situations the pieces are not given, we just assume they are there. We assume certain perceptions, certain concepts and certain boundaries. (Wikipedia, 2006)Lateral thinking is concerned not with playing with the existing pieces but with seeking to change those very pieces. Lateral thinking is concerned with the perception part of thinking. This is where we organize the external world into the pieces we can then ‘process'. (de Bono, 1994b) Third, â€Å"The brain as a self-organizing information system forms asymmetric patterns. In such systems there is a mathematical need f or moving across patterns. The tools and processes of lateral thinking are designed to achieve such ‘lateral' movement. The tools are based on an understanding of self-organizing information systems.† (de Bono, 2004). This is a technical definition which depends on an understanding of self-organizing information systems.Fourth, â€Å"In any self-organizing system there is a need to escape from a local optimum in order to move towards amore global optimum. The techniques of lateral thinking, such as provocation, are designed to help that change.† (de Bono, 2005). This is another technical definition. It is important because it also defines the mathematical need for creativity. Lateral thinking is about reasoning that is not immediately obvious and about ideas that may not be obtainable by using only traditional step-by-step logic.Techniques that relate lateral thinking to problems are characterized by the shifting of thinking patterns away from predictable or entre nched thinking to new or unexpected ideas. A new idea that is the result of lateral thinking is not always a helpful one, but when a good idea is discovered in this way it is usually obvious in hindsight, which is a feature lateral thinking shares with a joke. (Harleys, 2004) Edward de Bono points out that the term problem solving, â€Å"implies that there is a problem to respond to and that it can be resolved. That eliminates situations where there is no problem or a problem exists that cannot be resolved. It is logical to think about making a good situation that has no problems, into a better situation. Some times a problem cannot be solved by removing its cause.† (de Bono, 1994a)Lateral thinking can be used to help in solving problems but can also be used for much more. (Wikipedia, 2006) With ‘parallel thinking' both sides (or all parties) are â€Å"thinking in parallel in the same direction.† (Davis, 2005) There is co-operative and co-ordinate thinking. The d irection itself can be changed in order to give a full scan of the situation. But at every moment each thinker is thinking in parallel with all the other thinkers. There does not have to be agreement. Statements or thoughts which are indeed contradictory are not argued out but laid down in parallel. In the final stage the way forward is ‘designed' from the parallel thought that have been laid out. (Davis, 2005)MethodsAn easy and convenient way of carrying out ‘parallel thinking' is the Six Hats method which is now being used commonly worldwide both because it speeds up thinking and also because it is so much more constructive then conventional argument thinking. (de Bono, 2005) The use of the Six Hats method is now growing speedily globally. Those who have become familiar with the technique look back at argument as primitive, crude and ego-driven. (de Bono, 2002)â€Å"With the Six Hats method you can still show off. But you now show off by performing better than anyone else under each hat. It is no longer a matter of proving someone else to be wrong. Our ingrained habits of critical disagreement are so often not just a matter of sensible caution, but a mixture of ‘power plays' and ego strutting.† (de Bono, 2003) On the other hand, there is a necessary and proper place for caution. â€Å"That place is provided by the ‘black hat’.† Under this hat every person sets out to look for dangers, risks, shortfalls, problems, etc. Even those who most like the idea make a authentic effort to recognize the faults. Power plays have no place. There is no longer an chance to show that some particular individual is wrong or that you are smarter than that person. (de Bono, 2003)There are six symbolic hats, each one a diverse color. The thinker wears one hat at a time and only uses the mode of thinking which goes with that particular color. â€Å"The white hat is neutral.† While wearing this hat, the thinkers simply focus on in formation. What information is available on the subject, and what is missing? â€Å"The red hat signifies emotion and intuition – aspects of human thinking which are traditionally excluded from ‘rational' discussion. But since they still exist, they often get expressed indirectly.† The red hat allows them to be expressed usefully and openly. â€Å"The black hat puts the thinkers into the role of judge.† Wearing this hat, they assess the risks associated with an idea and see how the idea fits with what is already known (our values, experience, objectives, etc.). (de Bono, 2003)â€Å"The yellow hat brings out the positive side of assessing an idea.† With this hat on, the thinkers look for the values and benefits in an idea. As with the black hat, the thinkers have to use logic when wearing the yellow hat.   â€Å"The green hat signals deliberate creative effort.† Under this hat all the possibilities can be discovered, using precise techniques of lateral thinking, like provocation. This is an chance for vision. Lastly, the â€Å"blue hat is there for the overview.† (de Bono, 2003)   It is typically worn by the person chairing a meeting but can be used by anyone. The process of thinking is managed with this hat and all the different threads drawn together. (Hellers, 2006)How can it be applied to the corporate world?Lateral thinking is of very great importance in such a way that it gives a new and an alternative way of solving a problem. By the use of lateral thinking, an individual can recognize dominant ideas that polarize perception of a problem, the person can search for different ways at looking things, can have a complete control of rigid thinking, can use a chance to encourage other ideas. Lateral thinking can also be applied in human problem solving. Lateral thinking can be used in the management development. This lateral thinking can be greatly used in schools where in de Bono had also done his study(. Cu rtin, 2004)Lateral thinking is also perfect for: Groups in need of new thinking like companies with an â€Å"innovation† initiative in need of tools that actually work; Professionals in the new idea development business — R&D, PD, marketing, advertising; Executives feeling the heat, same old, same old just isn't working anymore; Teams frustrated with old predicable ideas that keep surfacing in their creative thinking meetings, Scientists and engineers who need systematic tools to break open their thinking; Proactive people that want to strengthen their Innovation Instinct— their ability to generate, build on and implement valuable new ideas. Human resource / Organization development professionals needing tools to facilitate ideation meetings; (de Bono Thinking Systems, 2006)Lateral thinking will also help individuals to develop skills to: Increase productive idea output; Design the future; Find fresh new solutions to intractable problems; Escape the constraints of routine thinking; Appreciate the diversity of thinking among team members; Plan and lead innovation meetings that deliver powerful results; Secure company’s leadership edge; Find new areas of opportunity. (de Bono, 2004)Hence, Lateral thinking is an alternative way to solve problem in a different approach. It could also greatly help in strengthening your business with fresh new thinking bringing innovative solutions to life. Lateral Thinking provides a flexible framework with systematic creativity tools so that you can.Referencesde Bono, E. (1994) Parallel Thinking. London: Viking.de Bono, E.

Review of Interventions That Apply Scripture in Psychotherapy Essay Example

Review of Interventions That Apply Scripture in Psychotherapy Essay Example Review of Interventions That Apply Scripture in Psychotherapy Essay Review of Interventions That Apply Scripture in Psychotherapy Essay Summary Garzon (2005) seeks to describe ways in which a therapist may use Scripture within psychotherapy interventions and to increase the awareness of therapists in these techniques. He bases this description by utilizing a case study by the name of George. Garzon contemplates issues surrounding scripture interventions. The article proceeds to relate interventions that use implicit scripture, psycho educational, theo educational, behavioral, cognitive, and affective experiential approaches. Ethical concerns are present within this discussion. Garzon (2005) relates to the reader that one must acknowledge that within these interventions dual relationships occur, boundaries may be violated between church and state, an imposition of values and issues such as informed consent and competency of the counselor do arise. Ways to avoid these ethical pitfalls are to have a inclusive conformed consent, conduct assessments that clearly define the clients spiritual beliefs, and use the scripture interventions only with certain clients (Garzon). The religious background of both counselor and client must be positive to avoid negative outcomes such as guilt. Implicit integration may include empathetic stance of the counselor, praying for the client, and the spiritual life of the counselor. Garzon (2005) also covers integration with psychoeducational approaches. This is exemplified through providing a client with scripture that shows the emotions of Christ or the trials of Job as two possibilities to use with someone on emotions and grief process respectively (Garzon). Another intervention to use with the case study is a theoeducational avenue. Garzon shows that he clients comments pointed to the heavy view of sin nature while minimizing the love of God. Work in this area and with his view of his father allowed the client to re evaluate his theological stance. Behavioral and cognitive approaches are also suggested (Garzon, 2005). Teaching breathing techniques can be integrated using scripture verses upon breathing out. The cognitive approach suggested is using REBT or Greenberger and Padeskys (as cited by Garzon) seven column technique. Inductive reasoning is utilized and scripture can be incorporated to adjust the way the the client thinks. Using scripture as an affective experiential approaches is also explained by Garzon. Here he allows the client to put himself into scripture through meditating on a specific part and allowing God to heal through this experience. Garzon (2005) uses this article to highlight some techniques and allows the reader an opportunity to expand their ability to integrate Christianity. It is noted that this was not all inclusive of every technique utilizing scripture but merely an example of professional Christians working with scripture with other Christians. Interaction This article was informative. The technique that resonated most with me was the affective experiential technique. I believe this approach can be highly effective but also requires a clinician that has an adequate basis of both scripture and psychology. When considering how powerful this can be the counselor must be sure of the clients need and the therapists ability to take the client before the Savior. In this article, Garzon (2005) speaks of using the story of the woman in need of healing but changes it to the self esteem problem of his client. By putting the client as the character in the story he was able to experience a transformation from Christ. This is incredibly powerful and in my opinion should only be used by someone trained in this technique. The cognitive approach seems to fit nicely with Christian perspective. A Christian is to form their thinking, attitudes and actions according to the Bible. Therefore it only makes sense to take irrational thoughts or ideas and reformulate these thoughts to bring about new attitudes and actions. The behavioral approach mentioned as well helps the Christian client to relax utilizing helpful scripture. Scripture can be used in a theoeducational and a pychoeducational way to provide help to clients. As Garzon (2005) provides an example, using Job when dealing with grief. Many people may find comfort, guidance and clarity through scripture. A counselor would have to watch for the pitfall of pushing their views onto the client. If both come from the same background or if the counselor has great understanding of the clients belief system the risk would be reduced. Application The use of prayer and scripture in psychotherapy is something that Christian therapists and some non Christian therapists may choose to use within their sessions with Christian clients. An example of using scripture and prayer in a case where the client was experiencing racing thoughts and anxiety over too many problems occurring at one time; A counselor could assess the client to see if they agree with the statement that God wants to receive your burdens and heal your heart while sanctifying you. The counselor could even simply give these following scripture verses to the client: Romans 5:3-4, Philippians 4:6-7, 1Peter 5:7 and Psalm 54:22. The sense that one is not alone and can go to the Lord with their burdens can help to ease anxiety. The client can write their burdens on paper and place into a box. In prayer present them to the Lord asking Him to give peace, guidance and clarity. The client can take the problem with the Holy Spirit guidance and then work on that one area with the rest of the problems resting with the Lord. This exercise can help to relieve some anxiety while also dealing with issues. The idea, â€Å"God wants to receive your burdens and heal your heart while sanctifying you† can also be a thought that one can breath through when thoughts begin to race. Inner healing prayer seems fascinating to me. The â€Å"desire to bring these core issues and connected emotions ‘into the living presence of God’ for processing, as well as for processing with the therapist are the goal. This could be quite effective for those struggling with irrational beliefs about themselves and feelings of helplessness as well as many other conditions. This powerful experience could be life changing. Overall, there is significant benefit to understanding the spiritual beliefs of the client and as a Christian counselor to center the therapy on Christ. References Garzon, F.

Last Days of Socrates essays

Last Days of Socrates essays Socrates was called The Hero of Western Philosophy. He had an inner conscience. He would hold gatherings in market places and his main aim was to improve the social and political structure of the country. He adopted the method of questioning and he would use the two steps to his method of questioning which was pleading ignorance and cross questioning. These two methods were used by him for the examination of basic moral concepts which were the virtues of piety, wisdom, temperance, courage, and justice. He would say I know that I know nothing. This was also called dialectic or elanchus.He also envisioned a perfect state called Republic where the rulers of the city would be philosophers. He also said that Truth lies beyond the shadows of our everyday experiences and only a philosopher could show how incapable we are and only he could rule a state. He felt that knowledge and life experiences make a person virtuous and just. The trial of Socrates was a major incident in Greek history. Socrates was accused of corrupting the youth of Athens and not worshipping the gods of the state. During his trial, he denied all accusations and attempted to defend himself by proving his innocence using reason. He was judged to be guilty and given a death sentence. He was found guilty and sentenced to death by drinking hemlock (172). Meanwhile, Socrates was also given an option of escaping the death sentence. He was asked to recant his beliefs and by doing this, he could have escaped the death penalty. But, since Socrates choose truth, he didnt prefer the option of escaping the death sentence. Instead he preferred death I am not going to alter my conduct, even if I have to die a hundred deaths (83). Socrates felt that verdicts must be carried out; irrespective of the fact that they we ...

South African Trevor Noah Gets Daily Show

South African Trevor Noah Gets 'Daily Show' Comedy Central announced that Trevor Noah would take over as host of The Daily Show after Jon Stewart leaves the show in late 2015 or early 2016. Noah, 31, is a South African comedian, actor and writer who had become a recurring guest on Stewart’s show since appearing for the first time in December 2014. Though he’s a bonafide star in South Africa, Noah is little-known in the United States and was a something of a surprising choice to host what has become an iconic and important American TV program. Within 48 hours of the network’s announcement, Noah was already in trouble for tweets he had posted over the years that some claimed were offensive to women, Jews and minorities. Noah’s mother is half Jewish, a black South African, and his father is white and of Swiss-German descent. To reduce my views to a handful of jokes that didn’t land is not a true reflection of my character, nor my evolution as a comedian, he tweeted in response to the criticism. A South African citizen of Noah’s talent will have little trouble landing a work visa from U.S. immigration officials - perhaps a P visa that’s often used for performers, entertainers or professional athletes. Most major league baseball players, for example, come to the United States to on an O-1 or P-1 visa. The O visa is for immigrants who demonstrate â€Å"extraordinary ability† in some field, for example, science, the arts or professional sports. The O visa generally is for all-star caliber athletes. Once he gets set up at Comedy Central, it should be a relatively easy matter for Noah to get a green card and attain legal permanent residency. U.S. immigration officials are ready to give status to foreign nationals with extraordinary talents that will contribute to the U.S. economy, as well as culture and the arts. Prominent South Africans who have come here and ultimately earned their U.S. citizenship include recording star Dave Matthews, Academy Award-winning actress Charlize Theron and inventor/entrepreneur Elon Musk. Other well-known South Africans who live much of their years in the United States include golfer Gary Player, tennis players Cliff Drysdale and Johan Kriek, economist Robert Z. Lawrence, actress Embeth Davidtz and musicians Trevor Rabin and Jonathan Butler. South Africans began migrating to the United States in the late 19th century and today, according to the U.S. Census Bureau, about 82,000 U.S. residents trace their origins to the country at the southern tip of the continent. During the 1980s and 1990s, thousands of South Africans fled to the United States for political reasons, escaping the civil strife in their homeland over apartheid and racial division. Many white South Africans, most notably Afrikaners, emigrated out of fears of what would happen when the inevitable transfer of power to the black population occurred under Nelson Mandela. Most South Africans living in the U.S. today are whites of European heritage. According to U.S. immigration officials, non-immigrant visas are  processed  in  Visa Sections at  three United States  Consulates in South Africa located in Johannesburg, Cape Town, and Durban.  U.S. Consulate Johannesburg processes applications for Immigrant Visas to the U.S.  The U.S. Embassy in Pretoria does not provide any visa services. Applicants for visas in the Pretoria area should apply at the U.S. Consulate Johannesburg.

Writing activities - Article Example Another important aspect which has been under consideration is that the quality of social media friendships differs from that of offline friendships. Off-line friendships and social media friendships both have their own charm and each type has its own uniqueness and special characteristics. Offline friendships have known to exist since forever. When a young child starts his education from the level of kindergarten, the first friend that he makes is through this type of friendship. This companionship is special and interaction begins mainly through face to face conversations. Offline friendships are cherished and people in this type of friendship share a bond which is mainly created by the physical presence of each other. These friendships are effective and emotions and expressions are far more easily expressed. This is because these friendships commence mainly through physical meetings and the two friends have actually seen each other. Friends at school, in the neighbourhood and in family are known better and tend to be generally closer. The special thing about off-line friendships is the warmth and care that friends can provide to each other through physical presence in difficult situations in one’s life. On the other hand, social media friendships which have gained substantial fame nowadays have their own appeal. These friendships have become popular amongst all age groups and provide a means for people to communicate even when they are far away. With the current busy lives of all individuals, people have lesser time of meeting their friends. Computers and the internet have come to the rescue and have provided with this form of friendship. The distinctive characteristic of social media friendships is that people tend to be connected to each other and physical presence is not a necessity. A person can interact with people and make friends even

Freud's Defense Mechanisms Essay Example | Topics and Well Written Essays - 750 words - 1

Freud's Defense Mechanisms - Essay Example Freud believed that Ego reacts to the threat of the impulses of Id break in two ways: by blocking the revelation of impulses in conscientious behavior and by their distortion to such an extent that their initial intensity decreases or deviates. The major defense mechanisms are: denial, displacement, intellectualization, projection, rationalization, reaction formation, regression, repression, suppression, sublimation. All the defense mechanisms have two common characteristics: 1) they act at the unconscious level and so serve as the means of self-deception, and 2) they distort, deny or falsify one’s perception of the reality to make anxiety less threatening for an individual. As a rule, people seldom use only one defense mechanism, usually applying a combination of different mechanisms for the solution of the conflict and reduction of anxiety. Denial, displacement and repression are the three defense mechanisms representing special interest due to their ability to strongly dist ort the reality. In case of denial, an individual argues that the stimulus, provoking his anxiety, doesn’t exist. For instance, a father may deny the painful fact that his daughter is raped and murdered. He would behave as if nothing has happened (which protects him from the devastating grief ad depression). A wife may deny her husband’s unfaithfulness. Or imagine a child denying the death of his favorite cat and persistently continuing to believe that the cat is alive. Denial of reality takes place when people insist: â€Å"This cannot happen to me†, notwithstanding the evidences of the counter. This often occurs when people are informed that they have some mortal disease. According to Freud, denial is mostly common with small children and people of older age with low intellect. On the other hand, mature people with normally developed intellect may resort to it as well when they have traumatic experience. A wonderful example of denial is represented in a short story

Ethics Essay Example | Topics and Well Written Essays - 750 words - 43

Ethics - Essay Example Certainly, this corporate reputation could be easily misconstrued to imply that the company is doing well in all respects. Analyzes of the company’s past performance records reveal issues of ethical concerns related to discrimination of workers. This discrimination is occasioned by arbitrary termination of contracts and firing of employees. On 28th Jan 2015, the Liberty Institute filed a case against the company on behalf of an employee named Thomas Banks. In this lawsuit, the plaintiff accused the company of firing him on religious grounds (Ferrell, Fraedrich & Ferrell, 2013). Banks had received a pro-homosexuality newsletter from his employer, Ford Company, which aroused his concern to send a feedback disagreeing with the intended homosexual policy citing non-conjunction with the biblical subscriptions. This dismissal based on the religious inclination of an employee not only implied corporate negligence of workers’ welfare but also violated the Federal civil rights act of 1964. There are several replica of such discriminatory activities associated with Ford Motor Company. This paper analyzes the ethical flaws within Ford Company in order to provide mitigation alternatives. Ford Company continues to face severe and expensive lawsuits linking it to ethical negligence. Women employees within the company have experienced sexual harassment in the enterprise. Some of the discrimination cases have been judicially addressed while others still remain at large (Ferrell, Fraedrich & Ferrell, 2013). Discrimination within Ford takes different phases including gender, racial, and religious discrimination. It is factual that the primary aim of business organizations is to attain high-profit margins and customer loyalty. The achievement of the main corporate objectives results from the proper management of human resources to ensure high quality and

INTELLECTUAL PROPERTY LAW Essay Example | Topics and Well Written Essays - 2750 words

INTELLECTUAL PROPERTY LAW - Essay Example In order to give Dicky proper legal advice, it would be in order to understand the exact terms and conditions that his employment or engagement with Smythe and Dickinson stated. The importance of this contractual agreement would be to know if Dicky’s terms of employment terms provision spelled out agreements on whether the company was either the sole owner or joint owner of any work produced in course of employment (Sumpter 2006, p.77).. This is because section 11 of the Copyright, Designs and Patents Act states the criteria for ascertaining the ownership of any copyright material and provides that any work produced in the course of employment belong to the employer who is deemed as the first owner. In the event that there are no such terms or regulations, Dicky will be perfectly be in a right position to fully own the work. Under the copyright laws in England, there are certain qualifications that one has to fulfil before they are fully covered or protected by the law on copy right. First, a person must be a citizen of Britain based on the qualifications that are set by the British Nationality Act 1981 (Ross 2008, p.46). The other requirement is originality, it has to be ascertained that without doubt the work (Valuation Guidelnes) was his (Dicky’s) own expression of ideas and invention to be the first owner under Copyright, Designs and Patents Act S.11(1). This is of interest, as it will help in understanding the actual position of the nature of the legal position from which the company is claiming rights. Dicky can argue that the company has no copyrights over any of his productions when he undertakes it independently even if employed by Smythe and Dickinson. The other requirement to gain copyright is fixation, as was held in the Merchandising Corp v Harpbond (1983), for instance the work has to be in a material form of which the valuation guidelines are in print and Dicky’s Antiques is in a DVD. Having ascertained Dickys terms of employm ent, citizenship, fixation and originality such that the Valuation Guidelines were his creative creation work; Dicky should understand the rights that a copyright holder have in relation to that particular original idea, which is automatic in UK upon meeting copyright requirements. Section 16 of the Copyright, Designs and Patents Act gives the copyright holder the right to copy the work and issue it to the public as well as broadcasting the work in a cable service program (McCombs 2011, p.21). All copyrighted material must possess originality as proposed in the case of University of London Press v University Tutorial Press (1916) 2 CH 601. This case discussed the doctrine known as sweat of the brow doctrine and if the word â€Å"original† is taken to refer to the originality of an expression for a certain piece of work to gain copyright protection (Harms 2008, p.133). The concept of originality tries to evaluate the relationship between the author of a particular piece of wor k and his work and is essential for a piece of work to gain copyright protection in England. This is expressly provided for under Section 1(1) of the Copyright, Designs and Patents Act 1988, s.1(1) and involves judicial reasoning and logic in the solution of cases. In order for Dicky to succeed in his defence, he must

Coal impact on the environment Essay Example | Topics and Well Written Essays - 750 words

Coal impact on the environment - Essay Example They tend to have an effect on the air, water as well as the animals. It also harms the health of the human beings (Finkelman et al 1999; Hill 2010). The burning of coal results in the production of many chemical substances which mainly include carbon dioxide, sulphur dioxide and nitric oxide. Coal also does not undergo complete combustion and ash is a substance which remains after the combustion of coal. Carbon dioxide is a greenhouse gas and it is released in very high amounts by the burning of coal. This increase in the amount of carbon dioxide in the air results in increasing the temperature of the world and promotes the phenomenon of global warming. Sulphur dioxide is also a harmful gas and results in the formation of acid rain. Nitric oxide is also a toxic gas which can result in the formation of an even more unstable substance known as toxic and at the same time nitric oxide also has the capability of causing acid rain (International Labour Office et al 1994). The quantity of ash that is released during the process of mining and burning is extensively high. It has been analyzed in the United States on an annual basis approximately 100 million tons of ash is produced due to the combustion of almost one billion ton of coal. Forty percent of the ash can be reutilized for forming other products which include cement but a large proportion still remains. The ash has a tendency to accumulate on land as well as it can make its way towards the water reservoirs and contaminate them by forming acids and follow the process of further addition of metals. Ash is disposed off in areas under the land and it is also kept in ‘ponds’ so that it can stay moistened. If proper regulations are not undertaken underground ash can also enter the underground water. Ponds also need to be checked and regulated because an incident occurred in the year 2008 when there was a spillage of the moistened coal and it resulted in contaminating the water in the river and a group of Tennessee individuals (Hill 2010; Mackenzie et al 2005). The mining of coal also results in the production of radioactive substances; though the quantity of the released substances is not very high. It has been analyzed that the population residing near the coal plants receive a higher rate of contact with these radiations than do the people who reside near nuclear power plants. This is because of the fact that the regulations at the nuclear power plants are strict and hence they minimize the release of radiations into the atmosphere (Hill 2010). The procedure of the mining of coal also carries many environmental affects. The mining which takes place on the surface as well as underground mines result in the contact of the rocks which are made up of sulphur to air and oxygen. This results in the formation of sulphur dioxide. This acid further tends to worsen the effect by acting on the rocks and causing them to release metals. The acid plus the metals gain ways to the water reserv oirs. This results in contaminating the water reservoirs and it harms the life that exists in water. It is found to be harmful not only for the microorganisms in the water but it also results in the death of fishes. These contaminated substances also tend to impact the land as well (Hill 2010; Mackenzie et al 2005). The burning of coal can also result in many harmful effects on the health of the human beings. ‘Black Lung Disease’

Describe a major result of the Civil War on the U.S and assess whether Essay

Describe a major result of the Civil War on the U.S and assess whether the result was good or bad for the country - Essay Example Their money was no good and their homes, buildings and infrastructure demolished. It is estimated that one in four males of military age in the South either died or suffered a crippling injuring during the war (â€Å"The Civil War†, n.d.). There is no credible argument regarding these two outcomes as to whether they were good or bad for the nation. Though rejoining the country is still today a celebrated event in U.S. history, it ultimately caused a negative outcome. The main reason that the Confederacy succeeded from the Union was the issue of States’ rights which are guaranteed by the Constitution but were almost completely lost following the Civil War. In most instances, individual states have the primary legal authority to nullify any actions taken by the federal government as described in the U.S. Constitution. This includes many legal rights up to and including the right to succeed. The Founding Fathers drafted this concept into the Constitution because they knew all too well that a decentralized federal government is less likely to become tyrannical because the people are better able to hold it accountable. The Founders’ intent was not necessarily to give the states additional powers but to limit the authority of the federal government and to alleviate the fear that it would exercise powers it was not given. This concept was understood by the Founders, the Confederacy and many of both conservative and liberal ideology since the earliest beginnings of the nation (Epstein, 2003). Within Article I, Section Eight of the Constitution is a purposely restricted set of responsibilities allocated to the federal government. It prints the money, regulates commerce and provides for the common defense, in other words, funds the military. The 1819 U.S. Supreme Court decided that the federal government also possessed certain ‘implied powers’ in the McCulloch v. Maryland
