Sample records for actuarial analysis

  1. Actuarial contributions to life table analysis.

    Lew, E A

    1985-05-01

    The correct principles for the construction of life tables and more particularly select life tables were developed by actuaries in England in the first half of the 19th century. Actuaries explored the phenomenon of selection not only between the insured and annuitants but also in the general population, distinguishing among initial temporary selection, antiselection, and class selection. The conclusion was reached early that no such thing as an unselected population exists. Group life insurance experience among the actively employed has been shown to provide a more appropriate standard of expected mortality than general population death rates in studies of medical impairments and occupational hazards at ages under 65 years. Mortality rates derived from the Cancer Prevention Study can serve as a useful standard of expected mortality when the objective is determination of excess mortality compared with ostensibly healthy persons at ages 65 years and older.

  2. Actuarial and actual analysis of surgical results: empirical validation.

    Grunkemeier, G L; Anderson, R P; Starr, A

    2001-06-01

    This report validates the use of the Kaplan-Meier (actuarial) method of computing survival curves by comparing 12-year estimates published in 1978 with current assessments. It also contrasts cumulative incidence curves, referred to as "actual" analysis in the cardiac-related literature with Kaplan-Meier curves for thromboembolism and demonstrates that with the former estimate the percentage of events that will actually occur.

  6. An analysis of possible applications of fuzzy set theory to the actuarial credibility theory

    Ostaszewski, Krzysztof; Karwowski, Waldemar

    1992-01-01

    In this work, we review the basic concepts of actuarial credibility theory from the point of view of introducing applications of the fuzzy set-theoretic method. We show how the concept of actuarial credibility can be modeled through the fuzzy set membership functions and how fuzzy set methods, especially fuzzy pattern recognition, can provide an alternative tool for estimating credibility.

  7. Long-term actuarial survivorship analysis of an interspinous stabilization system.

    Sénégas, Jacques; Vital, Jean-Marc; Pointillart, Vincent; Mangione, Paolo

    2007-08-01

    In 1986, an interspinous dynamic stabilization system (the prototype of the current Wallis implant) was designed to stiffen unstable operated degenerate lumbar segments with a hard interspinous blocker to limit extension and a tension band around the spinous processes to secure the implant and limit flexion. Restoring physiological mechanical conditions to the treated level(s) while preserving some intervertebral mobility was intended to treat low-back pain related to degenerative instability without increasing stress forces in the adjacent segments. The procedure was easily reversible. If low back pain persisted or recurred, the device was removed and stability was achieved using fusion. The intermediate-term results were promising, but the long-term safety and efficacy of this dynamic interspinous stabilization device has not been previously documented. We retrospectively reviewed the hospital files of all the patients (n = 241) who had this dynamic stabilization system implanted between 1987 and 1995, contacting as many as possible to determine the actuarial survivorship of the system. In this manner, 142 of the 241 patients (58.9%) were contacted by telephone. The endpoints used for the survivorship analysis were 'any subsequent lumbar operation' and 'implant removal'. At 14 years follow-up, values of actuarial survivorship with 95% confidence interval were 75.9 +/- 8.3 and 81.3 +/- 6.8% for the endpoints 'any subsequent lumbar operation' and 'implant removal', respectively. There was no difference in survivorship of multiple-level implants with respect to single-level devices. Although the conclusions of the present study must be tempered by the 41% attrition rate, these findings support the long-term safety of this system, and possibly long-term protective action against adjacent-level degeneration by motion preservation. Outcomes at least equivalent to those of fusion were observed without the primary drawbacks of fusion.

  9. Clinical versus actuarial judgment.

    Dawes, R M; Faust, D; Meehl, P E

    1989-03-31

    Professionals are frequently consulted to diagnose and predict human behavior; optimal treatment and planning often hinge on the consultant's judgmental accuracy. The consultant may rely on one of two contrasting approaches to decision-making--the clinical and actuarial methods. Research comparing these two approaches shows the actuarial method to be superior. Factors underlying the greater accuracy of actuarial methods, sources of resistance to the scientific findings, and the benefits of increased reliance on actuarial approaches are discussed.

  15. An analysis of a three-factor model proposed by the Danish Society of Actuaries for forecasting and risk analysis

    Jørgensen, Peter Løchte; Slipsager, Søren Kærgaard

    2016-01-01

    This paper provides the explicit solution to the three-factor diffusion model recently proposed by the Danish Society of Actuaries to the Danish industry of life insurance and pensions. The solution is obtained by use of the known general solution to multidimensional linear stochastic differential...... equation systems. With offset in the explicit solution, we establish the conditional distribution of the future state variables which allows for exact simulation. Using exact simulation, we illustrate how simulation of the system can be improved compared to a standard Euler scheme. In order to analyze...... the effect of choosing the exact simulation scheme over the traditional Euler approximation scheme frequently applied by practitioners, we carry out a simulation study. We show that due to its recursive nature, the Euler scheme becomes computationally expensive as it requires a small step size in order...

  16. Survival Analysis and Actuarial Parameters of Sternechus subsignatus (Coleoptera: Curculionidae) Adults.

    Guillermina Socías, María; Van Nieuwenhove, Guido; Murúa, María Gabriela; Willink, Eduardo; Liljesthröm, Gerardo Gustavo

    2016-04-01

    The soybean stalk weevil, Sternechus subsignatus Boheman 1836 (Coleoptera: Curculionidae), is a very serious soybean pest in the Neotropical region. Both adults and larvae feed on soybean, causing significant yield losses. Adult survival was evaluated during three soybean growing seasons under controlled environmental conditions. A survival analysis was performed using a parametric survival fit approach in order to generate survival curves and obtain information that could help optimize integrated management strategies for this weevil pest. Sex of the weevils, crop season, fortnight in which weevils emerged, and their interaction were studied regarding their effect on adult survival. The results showed that females lived longer than males, but both genders were actually long-lived, reaching 224 and 176 d, respectively. Mean lifetime (l50) was 121.88±4.56 d for females and 89.58±2.72 d for males. Although variations were observed in adult longevities among emergence fortnights and soybean seasons, only in December and January fortnights of the 2007–2008 season and December fortnights of 2009–2010 did the statistically longest and shortest longevities occur, respectively. Survivorship data (lx) of adult females and males were fitted to the Weibull frequency distribution model. The survival curve was type I for both sexes, which indicated that mortality corresponded mostly to old individuals.

  17. Offering Lung Cancer Screening to High-Risk Medicare Beneficiaries Saves Lives and Is Cost-Effective: An Actuarial Analysis

    Pyenson, Bruce S.; Henschke, Claudia I.; Yankelevitz, David F.; Yip, Rowena; Dec, Ellynne

    2014-01-01

    Background By a wide margin, lung cancer is the most significant cause of cancer death in the United States and worldwide. The incidence of lung cancer increases with age, and Medicare beneficiaries are often at increased risk. Because of its demonstrated effectiveness in reducing mortality, lung cancer screening with low-dose computed tomography (LDCT) imaging will be covered without cost-sharing starting January 1, 2015, by nongrandfathered commercial plans. Medicare is considering coverage for lung cancer screening. Objective To estimate the cost and cost-effectiveness (ie, cost per life-year saved) of LDCT lung cancer screening of the Medicare population at high risk for lung cancer. Methods Medicare costs, enrollment, and demographics were used for this study; they were derived from the 2012 Centers for Medicare & Medicaid Services (CMS) beneficiary files and were forecast to 2014 based on CMS and US Census Bureau projections. Standard life and health actuarial techniques were used to calculate the cost and cost-effectiveness of lung cancer screening. The cost, incidence rates, mortality rates, and other parameters chosen by the authors were taken from actual Medicare data, and the modeled screenings are consistent with Medicare processes and procedures. Results Approximately 4.9 million high-risk Medicare beneficiaries would meet criteria for lung cancer screening in 2014. Without screening, Medicare patients newly diagnosed with lung cancer have an average life expectancy of approximately 3 years. Based on our analysis, the average annual cost of LDCT lung cancer screening in Medicare is estimated to be $241 per person screened. LDCT screening for lung cancer in Medicare beneficiaries aged 55 to 80 years with a history of ≥30 pack-years of smoking and who had smoked within 15 years is low cost, at approximately $1 per member per month. This assumes that 50% of these patients were screened. Such screening is also highly cost-effective, at <$19,000 per life

  18. Health insurance basic actuarial models

    Pitacco, Ermanno

    2014-01-01

    Health Insurance aims at filling a gap in actuarial literature, attempting to solve the frequent misunderstanding in regards to both the purpose and the contents of health insurance products (and ‘protection products’, more generally) on the one hand, and the relevant actuarial structures on the other. In order to cover the basic principles regarding health insurance techniques, the first few chapters in this book are mainly devoted to the need for health insurance and a description of insurance products in this area (sickness insurance, accident insurance, critical illness covers, income protection, long-term care insurance, health-related benefits as riders to life insurance policies). An introduction to general actuarial and risk-management issues follows. Basic actuarial models are presented for sickness insurance and income protection (i.e. disability annuities). Several numerical examples help the reader understand the main features of pricing and reserving in the health insurance area. A short int...

  19. An actuarial analysis shows that offering lung cancer screening as an insurance benefit would save lives at relatively low cost.

    Pyenson, Bruce S; Sander, Marcia S; Jiang, Yiding; Kahn, Howard; Mulshine, James L

    2012-04-01

    Lung cancer screening is not established as a public health practice, yet the results of a recent large randomized controlled trial showed that screening with low-dose spiral computed tomography reduces lung cancer mortality. Using actuarial models, this study estimated the costs and benefits of annual lung cancer screening offered as a commercial insurance benefit in the high-risk US population ages 50-64. Assuming current commercial reimbursement rates for treatment, we found that screening would cost about $1 per insured member per month in 2012 dollars. The cost per life-year saved would be below $19,000, an amount that compares favorably with screening for cervical, breast, and colorectal cancers. Our results suggest that commercial insurers should consider lung cancer screening of high-risk individuals to be high-value coverage and provide it as a benefit to people who are at least fifty years old and have a smoking history of thirty pack-years or more. We also believe that payers and patients should demand screening from high-quality, low-cost providers, thus helping set an example of efficient system innovation.

  20. Treatment referral for sex offenders based on clinical judgment versus actuarial risk assessment: match and analysis of mismatch.

    Smid, Wineke J; Kamphuis, Jan Henk; Wever, Edwin C; Van Beek, Daan

    2013-07-01

    The Risk Need Responsivity (RNR) principles (Andrews & Bonta, 2010) dictate that higher risk sex offenders should receive more intensive treatment. The present study investigates how clinically based treatment assignment relates to risk level in a sex offender sample from The Netherlands. Correlational analyses served to identify sources of mismatches: that is, variables differing significantly in their relation between treatment selection and risk level. Our study sample consisted of 194 convicted rapists and 214 convicted child molesters. All participants' criminal files were retrospectively coded in terms of the items of the STATIC-99R, PCL: SV, and SVR-20. A low to moderate correlation was observed between clinical treatment selection and actuarial risk levels. A substantial part of the sex offenders, especially child molesters, received overly intensive treatment and another substantial part, especially rapists, received treatment of lesser intensity than indicated by their risk levels. General violent and antisocial risk factors seemed to be underemphasized in the clinical evaluation of sex offenders, especially rapists. A negative attitude toward intervention was negatively associated with clinical treatment selection. It is concluded that clinical treatment selection leads to an insufficient match between risk level and treatment level and systematic use of validated structured risk assessment instruments is necessary to ensure optimal adherence to the risk principle.

  3. How Fair Is Actuarial Fairness?

    Landes, Xavier

    2015-01-01

    in exchange for the payment of premi- ums. In the insurance industry, the concept of actuarial fairness serves to establish what could be adequate, fair premiums. Accordingly, premiums paid by policyholders should match as closely as possible their risk exposure (i.e. their expected losses). Such premiums...... are the product of the probabilities of losses and the expected losses. This article presents a discussion of the fairness of actuarial fairness through three steps: (1) defining the concept based on its formulation within the insurance industry; (2) determining in which sense it may be about fairness; and (3......) raising some objections to the actual fairness of actu- arial fairness. The necessity of a normative evaluation of actuarial fairness is justified by the influence of the concept on the current reforms of public insurance systems and the fact that it highlights the question of the repartition of the gains...

  4. A look inside the actuarial black box.

    Math, S E; Youngerman, H

    1992-12-01

    Hospital executives often rely on actuaries (and their "black boxes") to determine self-insurance program liabilities and funding contributions. Typically, the hospital supplies the actuary with a myriad of statistics, and eventually the hospital receives a liability estimate and recommended funding level. The mysterious actuarial calculations that occur in between data reporting and receipt of the actuary's report are akin to a black box--a complicated device whose internal mechanism is hidden from or mysterious to the user.

  16. Choosing the 'best' plan in a health insurance exchange: actuarial value tells only part of the story.

    Lore, Ryan; Gabel, Jon R; McDevitt, Roland; Slover, Michael

    2012-08-01

    In the health insurance exchanges that will come online in 2014, consumers will be able to compare health plans with respect to actuarial value, or the percentage of health care costs that a plan would pay for a standard population. This analysis illustrates the out-of-pocket costs that might result from plans with various plan designs and actuarial values. We find that average out-of-pocket expense declines as actuarial values rise, but two plans with similar actuarial values can produce very different outcomes for a given person. The overall affordability of a plan also will be influenced by age rating, income-related premium subsidies, and out-of-pocket subsidies. Actuarial value is a useful starting point for selecting a plan, but it does not pinpoint which plan will produce the best overall value for a particular person.

  4. Do actuaries believe in longevity deceleration?

    Debonneuil, Edouard; Planchet, Frédéric; Loisel, Stéphane

    2015-01-01

    As more and more people believe that significant life extensions may come soon, should commonly used future mortality assumptions be considered prudent? We find here that commonly used actuarial tables for annuitants – as well as the Lee-Carter model – do not extrapolate life expectancy at the same rate for future years as for past years; instead they produce some longevity deceleration. This is typically because their mortality improvements decrease after a certain age, and those age-specifi...

  5. Actuarial senescence in a long-lived orchid challenges our current understanding of ageing

    Dahlgren, Johan; Colchero, Fernando; Jones, Owen;

    2016-01-01

    The dominant evolutionary theory of actuarial senescence – an increase in death rate with advancing age – is based on the concept of a germ cell line that is separated from the somatic cells early in life. However, such a separation is not clear in all organisms. This has been suggested to explain...... the paucity of evidence for actuarial senescence in plants. We used a 32-year study of Dactylorhiza lapponica that replaces its organs each growing season, to test whether individuals of this tuberous orchid senesce.

  6. An actuarial approach to retrofit savings in buildings

    Subbarao, Krishnappa; Etingov, Pavel V.; Reddy, T. A.

    2014-01-01

    An actuarial method has been developed for determining energy savings from retrofits from energy use data for a number of buildings. This method should be contrasted with the traditional method of using pre- and post-retrofit data on the same building. This method supports the U.S. Department of Energy Building Performance Database of real building performance data and related tools that enable engineering and financial practitioners to evaluate retrofits. The actuarial approach derives, from the database, probability density functions (PDFs) for energy savings from retrofits by creating peer groups for the user’s pre post buildings. From the energy use distribution of the two groups, the savings PDF is derived. This provides the basis for engineering analysis as well as financial risk analysis leading to investment decisions. Several technical issues are addressed: The savings PDF is obtained from the pre- and post-PDF through a convolution. Smoothing using kernel density estimation is applied to make the PDF more realistic. The low data density problem can be mitigated through a neighborhood methodology. Correlations between pre and post buildings are addressed to improve the savings PDF. Sample size effects are addressed through the Kolmogorov--Smirnov tests and quantile-quantile plots.

  7. 新型农村社会养老保险替代率精算分析%Actuarial Analysis of the Replacement Rate of New Rural Social Endowment Insurance

    黄锦英; 罗倩倩

    2011-01-01

    Based on the analysis of existing research literatures and the policy document about new rural endowment insurance which was put forward in September 2009,this paper tries to construct an actuarial model of endowment insurance replacement rate in order to make an empirical analysis of the replacement rate of new rural social endowment insurance.The result appears that the relationship between the payment years,payment level and the replacement rate level presents positive correlation.This paper also explores the reasons for the low level of replacement rate and the inefficiency of protection and finally puts forward some corresponding countermeasures in government subsidy,investment operations for individual account,payment methods,etc.%在分析已有研究文献的基础上,基于2009年9月出台的新型农村社会养老保险政策文件,依据相关规定和数据构建养老保险替代率精算模型,对新型农村社会养老保险替代率进行实证分析,测算出新制度下养老金缴费年限和缴费档次与替代率水平之间具有正向相关关系,探索新制度下养老金的替代率水平低及其预期保障力不足的深层次原因,并在政府补贴力度、个人账户投资运营以及缴费方式上提出相应的建议。

  15. Actuarial senescence in a long-lived orchid challenges our current understanding of ageing.

    Dahlgren, Johan Petter; Colchero, Fernando; Jones, Owen R; Øien, Dag-Inge; Moen, Asbjørn; Sletvold, Nina

    2016-11-16

    The dominant evolutionary theory of actuarial senescence-an increase in death rate with advancing age-is based on the concept of a germ cell line that is separated from the somatic cells early in life. However, such a separation is not clear in all organisms. This has been suggested to explain the paucity of evidence for actuarial senescence in plants. We used a 32 year study of Dactylorhiza lapponica that replaces its organs each growing season, to test whether individuals of this tuberous orchid senesce. We performed a Bayesian survival trajectory analysis accounting for reproductive investment, for individuals under two types of land use, in two climatic regions. The mortality trajectory was best approximated by a Weibull model, showing clear actuarial senescence. Rates of senescence in this model declined with advancing age, but were slightly higher in mown plots and in the more benign climatic region. At older ages, senescence was evident only when accounting for a positive effect of reproductive investment on mortality. Our results demonstrate actuarial senescence as well as a survival-reproduction trade-off in plants, and indicate that environmental context may influence senescence rates. This knowledge is crucial for understanding the evolution of demographic senescence and for models of plant population dynamics.

  20. ACTUARIAL TECHNIQUES TO ASSESS THE FINANCIAL PERFORMANCE. INSURANCE APPLICATIONS

    CORINA IOANĂŞ

    2012-01-01

    Full Text Available The XXI century was marked by the convergence and harmonization, this century is distinguished in that it lays the foundation of accounting actuarial, which is characterized by up to date values and actuarial calculations . Actuarial accounting is reflected best in insurance system. In the market economy, insurance system is on one hand a means of protecting the business and property of citizens, on the other hand a business that generates profits. From this context, we can say that the subject of actuarial accounting is the measurement and recognition of assets and result of the change in time value of money. Time is an important variable considered in any economic decision investing and financing.

  1. Valuing structured professional judgment: predictive validity, decision-making, and the clinical-actuarial conflict.

    Falzer, Paul R

    2013-01-01

    Structured professional judgment (SPJ) has received considerable attention as an alternative to unstructured clinical judgment and actuarial assessment, and as a means of resolving their ongoing conflict. However, predictive validity studies have typically relied on receiver operating characteristic (ROC) analysis, the same technique commonly used to validate actuarial assessment tools. This paper presents SPJ as distinct from both unstructured clinical judgment and actuarial assessment. A key distinguishing feature of SPJ is the contribution of modifiable factors, either dynamic or protective, to summary risk ratings. With modifiable factors, the summary rating scheme serves as a prognostic model rather than a classification procedure. However, prognostic models require more extensive and thorough predictive validity testing than can be provided by ROC analysis. It is proposed that validation should include calibration and reclassification techniques, as well as additional measures of discrimination. Several techniques and measures are described and illustrated. The paper concludes by tracing the limitations of ROC analysis to its philosophical foundation and its origin as a statistical theory of decision-making. This foundation inhibits the performance of crucial tasks, such as determining the sufficiency of a risk assessment and examining the evidentiary value of statistical findings. The paper closes by noting a current effort to establish a viable and complementary relationship between SPJ and decision-making theory.

  2. Human actuarial aging increases faster when background death rates are lower: a consequence of differential heterogeneity?

    Hawkes, Kristen; Smith, Ken R; Blevins, James K

    2012-01-01

    Many analyses of human populations have found that age-specific mortality rates increase faster across most of adulthood when overall mortality levels decline. This contradicts the relationship often expected from Williams' classic hypothesis about the effects of natural selection on the evolution of senescence. More likely, much of the within-species difference in actuarial aging is not due to variation in senescence, but to the strength of filters on the heterogeneity of frailty in older survivors. A challenge to this differential frailty hypothesis was recently posed by an analysis of life tables from historical European populations and traditional societies that reported variation in actuarial aging consistent with Williams' hypothesis after all. To investigate the challenge, we reconsidered those cases and aging measures. Here we show that the discrepancy depends on Ricklefs' aging rate measure, ω, which decreases as mortality levels drop because it is an index of mortality level itself, not the rate of increase in mortality with age. We also show unappreciated correspondence among the parameters of Gompertz-Makeham and Weibull survival models. Finally, we compare the relationships among mortality parameters of the traditional societies and the historical series, providing further suggestive evidence that differential heterogeneity has strong effects on actuarial aging.

  7. Has actuarial aging "slowed" over the past 250 years? A comparison of small-scale subsistence populations and European cohorts.

    Gurven, Michael; Fenelon, Andrew

    2009-04-01

    G.C. Williams's 1957 hypothesis famously argues that higher age-independent, or "extrinsic," mortality should select for faster rates of senescence. Long-lived species should therefore show relatively few deaths from extrinsic causes such as predation and starvation. Theoretical explorations and empirical tests of Williams's hypothesis have flourished in the past decade but it has not yet been tested empirically among humans. We test Williams's hypothesis using mortality data from subsistence populations and from historical cohorts from Sweden and England/Wales, and examine whether rates of actuarial aging declined over the past two centuries. We employ three aging measures: mortality rate doubling time (MRDT), Ricklefs's omega, and the slope of mortality hazard from ages 60-70, m'(60-70), and model mortality using both Weibull and Gompertz-Makeham hazard models. We find that (1) actuarial aging in subsistence societies is similar to that of early Europe, (2) actuarial senescence has slowed in later European cohorts, (3) reductions in extrinsic mortality associate with slower actuarial aging in longitudinal samples, and (4) men senesce more rapidly than women, especially in later cohorts. To interpret these results, we attempt to bridge population-based evolutionary analysis with individual-level proximate mechanisms.

  8. Throwing the baby out with the bath water: is it time for clinical judgment to supplement actuarial risk assessment?

    Abbott, Brian R

    2011-01-01

    The assessment of the potential for sexual violence is one of three prongs that must be met to satisfy the requirements for civil confinement of dangerous sex offenders in the 21 U.S. jurisdictions that have these laws. In a recent issue of The Journal, Sreenivasan et al. argued that, because of a host of methodological problems, actuarial risk assessment methods in general and the Static-99 and its progeny in particular are insufficient for accurate assessment of risk for dangerous sex offenders. They propose using a combination of clinical judgment with actuarial science as a solution. This analysis and review of Sreenivasan et al. reveals and corrects flaws in the arguments they employed to support their position and shows how the combination of actuarial science with clinical judgment is more error prone than the actuarial approach only, and cannot be forensically defended in court. Recommendations on reporting Static-99R data in expert testimony are provided, taking into account the limitations of the instrument.

  14. A Note on Realistic Dividends in Actuarial Surplus Models

    Benjamin Avanzi

    2016-10-01

    Full Text Available Because of the profitable nature of risk businesses in the long term, de Finetti suggested that surplus models should allow for cash leakages, as otherwise the surplus would unrealistically grow (on average to infinity. These leakages were interpreted as ‘dividends’. Subsequent literature on actuarial surplus models with dividend distribution has mainly focussed on dividend strategies that either maximise the expected present value of dividends until ruin or lead to a probability of ruin that is less than one (see Albrecher and Thonhauser, Avanzi for reviews. An increasing number of papers are directly interested in modelling dividend policies that are consistent with actual practice in financial markets. In this short note, we review the corporate finance literature with the specific aim of fleshing out properties that dividend strategies should ideally satisfy, if one wants to model behaviour that is consistent with practice.

  15. The Actuarial Society of South Africa AIDS model.

    1997-01-01

    The AIDS Committee of the Actuarial Society of South Africa has developed a demographic model to allow researchers to project the impact of HIV and AIDS in South Africa. The model is available for use as a projection tool rather than to endorse a given projected scenario as being representative. It is very flexible and can be adapted to suit different purposes by anyone with a working knowledge of Microsoft Excel. The need for a model, calibration of the model, the lack of allowance in the model for racial and cultural heterogeneity in the underlying population, and default scenario projections are discussed. The model is available free of charge via E-mail and on the worldwide web at the following respective addresses: awhitelo@oldmutual.com and http://www.und.ac.za/und/eco/eru/eru.htm.

    2008-01-01

    Full Text Available España ha seguido la tendencia de otros países en cuanto a la cobertura de las personas dependientes, es decir, aquellas que necesitan ayuda para realizar las tareas básicas de la vida diaria, y lo ha hecho mediante la aprobación de la Ley de Promoción de la Autonomía Personal y Atención a las personas en situación de Dependencia, que se basa en la financiación pública. A pesar de los esfuerzos para el desarrollo de la Ley, ésta no está dando los frutos que debiera haber dado y se hace necesaria la existencia de productos privados de cobertura que puedan atender a las necesidades de aquellos que los demandan. Dado los escasos estudios que sobre este tema existen todavía en nuestro país, el establecer una aproximación a las primas de un seguro privado de dependencia puede servir de referencia para el análisis de su comercialización por parte de las aseguradoras. En este trabajo se trata de analizar una serie de cuestiones que den respuesta a dos objetivos. Por una parte, establecer un modelo financiero-actuarial que sirva como apoyo en el diseño de productos privados que cubran la dependencia y, por otra, realizar una aproximación a las bases técnicas actuariales que lleven a la cuantificación de las primas. = Spain has followed the trend of other countries about long term care, that is, people who need help to perform the basic tasks of daily living. In December 2006, Spanish Parliament approved the law called Ley de Promoción de la Autonomía Personal y Atención a las personas en situación de Dependencia, with public financing. This law is not producing the expected results, and it makes necessary the existence of private insurance. Currently, there are few studies on long term care in our country. An approach to premiums of a private insurance can serve as reference for the studies by insurers. This work tries to study a series of questions responding simultaneously to two goals, establishing an actuarial model and, on

  20. The lifecontingencies Package: Performing Financial and Actuarial Mathematics Calculations in R

    Giorgio Alfredo Spedicato

    2013-11-01

    Full Text Available It is possible to model life contingency insurances with the lifecontingencies R package, which is capable of performing financial and actuarial mathematics calculations. Its functions permit one to determine both the expected value and the stochastic distribution of insured benefits. Therefore, life insurance coverage can be priced and portfolios risk-based capital requirements can be assessed. This paper briefly summarizes the theory regarding life contingencies that is based on financial mathematics and demographic con- cepts. Then, with the aid of applied examples, it shows how the lifecontingencies package can be a useful tool for executing routine, deterministic, or stochastic calculations for life-contingencies actuarial mathematics.

  1. Monitoring Actuarial Present Values of Term Life Insurance By a Statistical Process Control Chart

    Hafidz Omar, M.

    2015-06-01

    Tracking performance of life insurance or similar insurance policy using standard statistical process control chart is complex because of many factors. In this work, we present the difficulty in doing so. However, with some modifications of the SPC charting framework, the difficulty can be manageable to the actuaries. So, we propose monitoring a simpler but natural actuarial quantity that is typically found in recursion formulas of reserves, profit testing, as well as present values. We shared some simulation results for the monitoring process. Additionally, some advantages of doing so is discussed.

    It is difficult to overestimate Paul Meehl’s influence on judgment and decision-making research. His ‘disturbing little book’ (Meehl, 1986, p. 370) Clinical versus Statistical Prediction: A Theoretical Analysis and a Review of the Evidence (1954) is known as an attack on human judgment and a call for replacing clinicians with actuarial methods.

  9. Actuarial calculation for PSAK-24 purposes post-employment benefit using market-consistent approach

    Effendie, Adhitya Ronnie

    2015-12-01

    In this paper we use a market-consistent approach to calculate present value of obligation of a companies' post-employment benefit in accordance with PSAK-24 (the Indonesian accounting standard). We set some actuarial assumption such as Indonesian TMI 2011 mortality tables for mortality assumptions, accumulated salary function for wages assumption, a scaled (to mortality) disability assumption and a pre-defined turnover rate for termination assumption. For economic assumption, we use binomial tree method with estimated discount rate as its average movement. In accordance with PSAK-24, the Projected Unit Credit method has been adapted to determine the present value of obligation (actuarial liability), so we use this method with a modification in its discount function.

  10. Actuarial assessment of violence risk in hospital-based partner assault clinics.

    Hilton, N Zoe; Harris, Grant T; Holder, Norah

    2008-12-01

    Hospital-based partner assault clinics are a relatively recent addition to the community response to partner violence. In this study, 66% of 111 women attending hospital clinics for partner assault were physically injured and 43% reported death threats. Few concurrently used other services (shelters or police) and most relied on female friends and relatives for help. Many participants who currently lived with the perpetrator were contemplating leaving but only a third had made plans to do so. Participants faced an unusually high risk of future assault, according to both victim interview using the ODARA actuarial risk assessment and their own perceptions. Findings imply an important role for partner assault clinics and the feasibility of the victim service sector's using the same actuarial risk assessments as the criminal justice system.

  12. Long‐Term Post‐CABG Survival: Performance of Clinical Risk Models Versus Actuarial Predictions

    Carr, Brendan M.; Romeiser, Jamie; Ruan, Joyce; Gupta, Sandeep; Seifert, Frank C.; Zhu, Wei

    2015-01-01

    Abstract Background/aim Clinical risk models are commonly used to predict short‐term coronary artery bypass grafting (CABG) mortality but are less commonly used to predict long‐term mortality. The added value of long‐term mortality clinical risk models over traditional actuarial models has not been evaluated. To address this, the predictive performance of a long‐term clinical risk model was compared with that of an actuarial model to identify the clinical variable(s) most responsible for any differences observed. Methods Long‐term mortality for 1028 CABG patients was estimated using the Hannan New York State clinical risk model and an actuarial model (based on age, gender, and race/ethnicity). Vital status was assessed using the Social Security Death Index. Observed/expected (O/E) ratios were calculated, and the models' predictive performances were compared using a nested c‐index approach. Linear regression analyses identified the subgroup of risk factors driving the differences observed. Results Mortality rates were 3%, 9%, and 17% at one‐, three‐, and five years, respectively (median follow‐up: five years). The clinical risk model provided more accurate predictions. Greater divergence between model estimates occurred with increasing long‐term mortality risk, with baseline renal dysfunction identified as a particularly important driver of these differences. Conclusions Long‐term mortality clinical risk models provide enhanced predictive power compared to actuarial models. Using the Hannan risk model, a patient's long‐term mortality risk can be accurately assessed and subgroups of higher‐risk patients can be identified for enhanced follow‐up care. More research appears warranted to refine long‐term CABG clinical risk models. doi: 10.1111/jocs.12665 (J Card Surg 2016;31:23–30) PMID:26543019

  13. Thrown a curve. CMS' actuaries: healthcare spending will continue to increase, despite reform law promises.

    2011-08-01

    While CMS actuaries say the 2010 reform law will not slow the nation's healthcare spending in the coming decade, Mary Grealy, of the Healthcare Leadership Council, says the law "was basically a coverage bill. We just didn't get to the other half, which would be aimed at the cost-drivers in the system." She adds that the healthcare system will not control ongoing steep increases in spending until additional legislation reshapes the dominant public insurance plans.

    2016-05-01

    For prevention purposes, it is important that police officers can estimate the risk for delinquency among juveniles who were involved in a criminal offense, but not in the role of a suspect. In the present study, the Youth Actuarial Risk Assessment Tool for First-Time Offending (Y-ARAT-FO) was developed based solely on police records with the aim to enable Dutch police officers to predict the risk for first-time offending. For the construction of this initial screening instrument, an Exhaustive Chi-squared Automatic Interaction Detector (Exhaustive CHAID) analysis was performed on a data set that was retrieved from the Dutch police system. The Y-ARAT-FO was developed on a sample of 1,368 juveniles and validated on a different sample of 886 juveniles showing moderate predictive accuracy in the validation sample (area under the receiver operating characteristic curve [AUC] = .728). The predictive accuracy of the Y-ARAT-FO was considered sufficient to justify its use as an initial screening instrument by the Dutch police.

    Full Text Available El límite de ingresos es una herramienta útil para objetivar la carencia de rentas y permitir la obtención de pensiones no contributivas. Sin embargo, su aplicación práctica da lugar a escenarios de escasa justificación técnica o social, por lo que el uso de la equivalencia actuarial sería de gran utilidad para determinar de una forma más adecuada el verdadero estado patrimonial del individuo a lo largo del tiempo y, con ello, la realidad de sus derechos en materia de seguridad social. The limit of earnings is an useful tool to define the lack of income and allow access to a non-contributory pension. However, its practical application promotes scenarios with poor technical or social justification, so the use of actuarial equivalence would be useful to determine adequately the person’s real patrimony in the long term and, thus, the reality of their rights of social security.

  1. Ethical practice in sex offender assessment: consideration of actuarial and polygraph methods.

    Vess, James

    2011-09-01

    The current generation of community protection laws represents a shift in priorities that may see the individual rights of sex offenders compromised for the goal of public safety. At the center of many judicial decisions under these laws are the risk assessment reports provided by mental health practitioners. The widespread enactment of laws allowing for additional sanctions for sex offenders, and a burgeoning research literature regarding the methods used to assess risk have served to heighten rather than resolve the ethical concerns associated with professional practice in this area. This article examines ethical issues inherent in the use of two assessment methods commonly used with sex offenders in the correctional context, focusing on actuarial measures and polygraph tests. Properly conducted and adequately reported actuarial findings are considered to provide useful information of sufficient accuracy to inform rather than mislead judicial decision makers, although careful consideration must be given to the limitations of current measures in each individual case. Despite its increasing use, polygraph testing is considered controversial, with little consensus regarding its accuracy or appropriate applications. On the basis of the current state of the professional literature regarding the polygraph, its use with sex offenders raises unresolved ethical concerns.

  2. THE EVOLUTION AND FUTURE OF SOCIAL SECURITY IN AFRICA: AN ACTUARIAL PERSPECTIVE

    Fatima Badat

    2015-09-01

    Full Text Available Social Security in most African countries has evolved significantly in terms of perspectives, motives, governance as well as innovation of benefits and administration. African countries are slowly, one by one, beginning to reassess the role of social security in correcting several social ills. Empowerment programs and grants are increasingly being provided via social security to women and the youth. From the roots of social security, even very low income countries, some of which have recently experienced several years of civil war and extreme economic hardships, have begun to improve benefit structures and amounts, which include national medical benefits. The attention being provided to social security and how it fits into a nation’s plans to lift itself out of poverty is increasingly involving the actuarial profession from international organisations such as ILO and ISSA as well as consulting actuaries and academics. Assessing and ensuring sustainability of social security benefits requires actuarial valuations to take long-term consequences involving demographic changes into account in the face of providing the benefits in the short term; asset liability modelling to ensure adequate resources are held; ensuring that results are appropriately reported and communicated to key stakeholders; as well as developing long-term strategic plans and dynamic systems surrounding all of these issues. In this paper, the role of actuaries is brought to the centre of the increasingly changing face and evolving culture of social security in taking Africa closer to poverty alleviation. La Seguridad Social en la mayoría de los países africanos ha evolucionado significativamente en cuanto a perspectivas, motivos, gobernanza, así como en innovación en las prestaciones y la adminsitración.

  3. Youth Actuarial Risk Assessment Tool (Y-ARAT): The development of an actuarial risk assessment instrument for predicting general offense recidivism on the basis of police records.

    van der Put, Claudia E

    2014-06-01

    Estimating the risk for recidivism is important for many areas of the criminal justice system. In the present study, the Youth Actuarial Risk Assessment Tool (Y-ARAT) was developed for juvenile offenders based solely on police records, with the aim to estimate the risk of general recidivism among large groups of juvenile offenders by police officers without clinical expertise. On the basis of the Y-ARAT, juvenile offenders are classified into five risk groups based on (combinations of) 10 variables including different types of incidents in which the juvenile was a suspect, total number of incidents in which the juvenile was a suspect, total number of other incidents, total number of incidents in which co-occupants at the youth's address were suspects, gender, and age at first incident. The Y-ARAT was developed on a sample of 2,501 juvenile offenders and validated on another sample of 2,499 juvenile offenders, showing moderate predictive accuracy (area under the receiver-operating-characteristic curve = .73), with little variation between the construction and validation sample. The predictive accuracy of the Y-ARAT was considered sufficient to justify its use as a screening instrument for the police.

  5. Optimization of Actuarial Model for Individual Account of Rural Social Pension Insurance

    Wenxian; CAO

    2013-01-01

    This paper firstly analyzes different payment methods of individual account and the pension replacement rate under the pension payment method.Results show that it will be more scientific and reasonable for the individual account of new rural social pension insurance to adopt the actuarial model of payment according to proportion of income and periodic prestation at variable amount.The Guiding Opinions on New Rural Social Pension Insurance sets forth individual account should be paid at fixed amount,and the insured voluntarily selects payment level as per criteria set by the State.The monthly calculation and distribution amount of pension is the total amount of individual account divided by139.Therefore,it should start from continuation of policies and make adjustment of payment level in accordance with growth of per capita net income of rural residents.When condition permits,it is expected to realize transition to payment as per income proportion and periodic prestation at variable amount.

    The compound negative binomial model, introduced in this paper, is a discrete time version. We discuss the Markov properties of the surplus process, and study the ruin probability and the joint distributions of actuarial random vectors in this model. By the strong Markov property and the mass function of a defective renewal sequence, we obtain the explicit expressions of the ruin probability, the finite-horizon ruin probability,the joint distributions of T, U(T - 1), |U(T)| and inf 0≤n<T1 U(n) (i.e., the time of ruin, the surplus immediately before ruin, the deficit at ruin and maximal deficit from ruin to recovery) and the distributions of some actuariai random vectors.

  7. An actuarial approach to comparing early stage and late stage lung cancer mortality and survival.

    Goldberg, Sara W; Mulshine, James L; Hagstrom, Dale; Pyenson, Bruce S

    2010-02-01

    Comparing the mortality characteristics of different cohorts is an essential process in the life insurance industry. Pseudodisease, lead-time bias, and length bias, which are critical to determining the value of cancer screening, have close analogues in life insurance company management, including the temporal impact of underwriting. Ratios of all-cause mortality rates for cancer cohorts relative to standard population mortality rates can provide insights into early stage and late stage mortality differences, differences by age, sex, race, and histology, and allow modeling of biases associated with early stage detection or screening protocols. The Surveillance, Epidemiology and End Results (SEER) data set has characteristics that allow efficient application of actuarial techniques. We show the mortality burden associated with treated early stage lung cancer and that identifying all lung cancers at early stage could reduce US lung cancer deaths by over 70,000 per year.

  8. NEW METHOD TO OPTION PRICING FOR THE GENERAL BLACK-SCHOLES MODEL-AN ACTUARIAL APPROACH

    闫海峰; 刘三阳

    2003-01-01

    Using physical probability measure of price process and the principle of fairpremium, the results of Mogers Bladt and Hina Hviid Rydberg are generalized. In twocases of paying intermediate divisends and no intermediate dividends, the Black-Scholesmodel is generalized to the case where the risk-less asset (bond or bank account) earns atime-dependent interest rate and risk asset (stock) has time-dependent the continuouslycompounding expected rate of return, volatility. In these cases the accurate pricing formulaand put- call parity of European option are obtained. The general approach of option pricingis given for the general Black-Scholes of the risk asset (stock) has the continuouslycompounding expected rate of return, volatility. The accurate pricing formula and put- callparity of European option on a stock whose price process is driven by general Ornstein-Uhlenback (O-U) process are given by actuarial approach.

    2003-01-01

    Full Text Available La dependencia es un estado en el que se encuentran las personas que por razones ligadas a la falta o la pérdida de autonomía física, psíquica o intelectual tienen necesidad de asistencia y/o atención significativa para la realización los actos corrientes de la vida diaria. Dentro de la iniciativa privada, el sector asegurador juega un importante papel para la prestación de garantías derivadas de esta cobertura. Un aspecto fundamental en el estudio de esta cobertura es la consideración de los periodos de carencia y el tratamiento del contraseguro de primas durante los mismo. Se analiza el riesgo actuarial y su tratamiento en esta cobertura y la incidencia en la valoración actuarial de las primas por prestaciones de dependencia.

  10. A theoretical model of the evolution of actuarial senescence under environmental stress.

    Watson, H; Cohen, A A; Isaksson, C

    2015-11-01

    Free-living organisms are exposed to a wide range of stressors, all of which can disrupt components of stress-related and detoxification physiology. The subsequent accumulation of somatic damage is widely believed to play a major role in the evolution of senescence. Organisms have evolved sophisticated physiological regulatory mechanisms to maintain homeostasis in response to environmental perturbations, but these systems are likely to be constrained in their ability to optimise robustness to multiple stressors due to functional correlations among related traits. While evolutionary change can accelerate due to human ecological impacts, it remains to be understood how exposure to multiple environmental stressors could affect senescence rates and subsequently population dynamics and fitness. We used a theoretical evolutionary framework to quantify the potential consequences for the evolution of actuarial senescence in response to exposure to simultaneous physiological stressors--one versus multiple and additive versus synergistic--in a hypothetical population of avian "urban adapters". In a model in which multiple stressors have additive effects on physiology, species may retain greater capacity to recover, or respond adaptively, to environmental challenges. However, in the presence of high synergy, physiological dysregulation suddenly occurs, leading to a rapid increase in age-dependent mortality and subsequent population collapse. Our results suggest that, if the synergistic model is correct, population crashes in environmentally-stressed species could happen quickly and with little warning, as physiological thresholds of stress resistance are overcome.

    弹性退休制是应对老龄化的社会养老保险制度改革未来选择之一,因此研究该制度下的退休年金精算问题具有重要的理论与现实意义。本文运用二项分布拟合退休年龄,带跳的非连续随机微分方程拟合利率,带跳Feller过程拟合死力强度,分析了弹性退休制下退休年金寿险精算函数,给出了生命年金、退休年金、退休年金二阶矩精算现值与均衡净保费的表达式,并利用模型对相关精算函数进行模拟测算。这些公式为弹性退休制下的保险金、均衡保险费等提供了精算分析的理论基础,从而为我国养老保险制度改革的制度设计、防控养老保险帐户风险提供了依据。%The flexible retirement system is one of the options of society endowment insurance system to deal with the aging. Therefore, the pension annuity under the system has important impact on theory and practice. This paper investigates the actuarial function of retirement annuity under the flexible retirement system. Under the hypothesis that the distribution of the retirement age is binomial distribution, the interest rate is decided by the discontinuous stochastic differential equations with jumps, and the death intensity is decided by Feller process with a jump. The formulas of the retirement annuity are proposed, including the life annuities, insurance, net premiums and insurance actuarial present value of second moment, and the sim-ulatived estimation for the relevant actuarial functions is derived. These formulas provide the basis of the actuarial analysis of insurance and balance insurance under the flexible retirement system, thus they can be applied for the old-age insurance system and control of risk pension account in China.

  13. Capital offenders in Texas prisons: rates, correlates, and an actuarial analysis of violent misconduct.

    Cunningham, Mark Douglas; Sorensen, Jon R

    2007-12-01

    This study analyzed the records of 136 recently incarcerated capital murder offenders in the initial phase (M = 2.37 years, range = 6-40 months) of their life sentences in the Texas Department of Criminal Justice. Prevalence rates of institutional violence were inversely related to severity: potentially violent misconduct (36.8%), assaultive violations (14%), serious assaults (5.1%), and homicides (0%). Consistent with prior studies, factors correlated with assaultive misconduct included age (inversely), prior prison confinement, and concurrent robbery or burglary in the capital offense. A simplified Burgess scale entitled the Risk Assessment Scale for Prison-Capital (RASP-Cap) was moderately successful in identifying varying levels of improbability of committing violence-related misconduct however defined (AUC = .715-.766).

    Full Text Available La Ley 27/2011, de 1 de agosto, sobre actualización, adecuación y modernización del sistema de seguridad social, ha variado la escala de porcentajes aplicables a la base reguladora en función del número de años cotizados. Los nuevos porcentajes afectan a los trabajadores que se vayan a jubilar con periodos de cotización entre 15 y 37 años y, especialmente, a aquellos trabajadores cuyas pensiones sean bajas y puedan ser beneficiarios de complemento a mínimos. Estas variaciones, que se han ido produciendo en la escala de porcentajes a través de sucesivos cambios legislativos, han llevado al actuario a estudiar cuáles serían los porcentajes de equilibrio financiero-actuarial según el número de años cotizados y la edad de inicio en el mercado laboral para cubrir todas las pensiones que pueda causar el trabajador. The Law 27/2011 of 1 August, about updating, improvement and modernization of the social security system has changed the scale of percentages applicable to the regulatory base depending on the number of years of contributions. The new rates affect workers who are to retire on contribution periods between 15 and 37 years, and especially to those workers whose pensions are low and can receive minimum supplements. These variations, that have they occurred in the percentage scale through successive legislative changes, have led to the actuary to study what percentage of financial and actuarial balance would be according to the number of years of contributions and the age of onset in the labor market to cover all pensions that may cause the worker.

  18. Properties of actuarially fair and pay-as-you-go health insurance schemes for the elderly. An OLG model approach.

    Johansson, P O

    2000-07-01

    The aged dependency ratio or ADR is growing at a fast pace in many countries. This fact causes stress to the economy and might create conflicts of interest between young and old. In this paper the properties of different health insurance systems for the elderly are analysed within an overlapping generations (OLG) model. The properties of actuarial health insurance and different variations of pay-as-you-go (PAYG) health insurance are compared. It turns out that the welfare properties of these contracts are heavily dependent on the economy's dynamic properties. Of particular importance is the magnitude of the rate of population growth relative to the interest rate. In addition, it is shown that public health insurance is associated with an inherent externality resulting in a second-best solution.

    Full Text Available El presente modelo actuarial de tasa de interés justa, pondera de manera equilibrada el precio del dinero - tanto para un prestamista, como para el solicitante - en donde ninguna de las partes resulta más beneficiada en perjuicio de la otra. De este modo, sea cual sea la elección del enganche y plazo que el cliente decida, siempre obtendrá el precio óptimo del financiamiento solicitado. La función Z = f(x,y representa a la variable de tasa de interés justa, en donde ambas partes tendrían una relación del tipo “ganar - ganar”; es decir, que ambas partes resultan mutuamente beneficiadas de la operación crediticia y en la cual ninguna de ellas obtiene ventaja en perjuicio de su contraparte. El precio justo del crédito automotriz se encuentra sobre la superficie de una gráfica de tres dimensiones cuyos puntos óptimos convergen en el vector (x,y,z; que determina la tasa de interés i, para un crédito sano. El diseño de un modelo computacional permite que el usuario interactúe con las variables de enganche y plazo, para conocer cómo influyen en el comportamiento de su crédito; tanto en el pago mensual, como en los intereses, impuestos y seguros; ofreciéndole una corrida financiera a lo largo del plazo contratado. Así, el modelo actuarial es totalmente dinámico ya que se adapta a los escenarios que se propongan. Corolario de lo anterior, resulta que cualquier punto fuera de la superficie óptima de la gráfica implicaría una ventaja/desventaja para alguna de las partes; por lo que el presente modelo permite realizar análisis de sensibilidad para tomar decisiones ANTES de celebrar la operación, considerando diferentes escenarios para las variables (x,y; de este modo, el modelo representa una herramienta de PREVISIÓN e incluso de PREVENCIÓN para la toma de mejores decisiones financieras.

  6. Actuarial Assessment of Sex Offender Recidivism Risk: A Validation of the German version of the Static-991

    Martin Rettenberger

    2006-12-01

    Full Text Available The Static-99 and the RRASOR are actuarial risk assessment tools for evaluating the risk of sexual and violent recidivism in sexual offenders. The Static-99 was developed in 1999 by Karl R. Hanson (Canada and David Thornton (Great Britain and is in the mean time regularly used for risk assessment in North America and some countries in Europe. The RRASOR can be described as a predecessor of the Static-99 and was published by Hanson in 1997. At first we translated the revised version of the Static-99 (Harris, Phenix, Hanson & Thornton, 2003 and adapted the instrument and the manual to the forensic context in Germany and Austria (Rettenberger & Eher, 2006. In this retrospective study, interrater reliability and concurrent validity of the RRASOR and of the German adaption of the Static-99 is presented. Furthermore we evaluated the predictive accuracy of the Static-99 and the RRASOR and compared their results. The instruments were validated from file information of Austrian sexuel offenders, who were convicted between 1968 and 2002. Both the Static-99 and the RRASOR had good interrater reliability and concurrent validity. The Static-99 showed good predictive validity for general (r = .41, AUC = .74, sexual (r = .35, AUC = .74 and violent (r = .41, AUC = .76 recidivism, whereas the predictive accuracy of the RRASOR was moderate for general (r = .29, AUC = .66, sexual (r = .30, AUC = .68 and violent (r = .28, AUC = .67 recidivism. The Static-99 exhibited a higher accuracy for the prediction of sexual offender recidivism. Although further validation studies on German-speaking populations of sex offenders are necessary, these results support the utility of the German version of the revised version of the Static-99 in improving risk assessment of sexual offenders.

  7. Coherence and health care cost--RCA actuarial study: a cost-effectiveness cohort study.

    Bedell, Woody; Kaszkin-Bettag, Marietta

    2010-01-01

    Chronic stress is among the most costly health problems in terms of direct health costs, absenteeism, disability, and performance standards. The Reformed Church in America (RCA) identified stress among its clergy as a major cause of higher-than-average health claims and implemented HeartMath (HM) to help its participants manage stress and increase physiological resilience. The 6-week HM program Revitalize You! was selected for the intervention including the emWave Personal Stress Reliever technology. From 2006 to 2007, completion of a health risk assessment (HRA) provided eligible clergy with the opportunity to participate in the HM program or a lifestyle management program (LSM). Outcomes for that year were assessed with the Stress and Well-being Survey. Of 313 participants who completed the survey, 149 completed the Revitalize You! Program, and 164 completed the LSM. Well-being, stress management, resilience, and emotional vitality were significantly improved in the HM group as compared to the LSM group. In an analysis of the claims costs data for 2007 and 2008, 144 pastors who had participated in the HM program were compared to 343 non-participants (control group). Adjusted medical costs were reduced by 3.8% for HM participants in comparison with an increase of 9.0% for the control group. For the adjusted pharmacy costs, an increase of 7.9% was found compared with an increase of 13.3% for the control group. Total 2008 savings as a result of the HM program are estimated at $585 per participant, yielding a return on investment of 1.95:1. These findings show that HM stress-reduction and coherence-building techniques can reduce health care costs.

Predominan los errores de exageración de la edad, los cuales inflan la población de edades avanzadas, especialmente de los 80 años en adelante. Por ejemplo, la población de 95 años y más de edad del censo está inflada en 22%. Las tablas de vida incluyen una extrapolación de la mortalidad para edades mayores de 100 años. Con una muestra de alrededor de 7 mil adultos mayores se determina que el patrón de mortalidad de los derecho-habientes de pensión es menor que el de la población general. La esperanza de vida al nacer de hombres y mujeres resultó de 74,6 y 79,4 años, respectivamente y a la edad 60 fue de 20,6 y 23,2 años, respectivamente, en toda la población de Costa Rica, y de 22,0 y 25,3 años entre los derecho-habientes de pensión. Para tomar en cuenta la disminución de la mortalidad que probablemente ocurrirá en el futuro en Costa Rica se recomienda usar la tabla de vida proyectada para 2020-25.

  1. Propuesta de formulación financiero-actuarial de un seguro de dependencia y acercamiento a una aplicación práctica

    Mª Manuela Segovia

    2005-01-01

    Full Text Available En los países industrializados, convergen dos fenómenos demográficos, la longevidad y la escasa natalidad, que provocan un envejecimiento de la población y con ello una serie de procesos sociales que son necesarios atender. Uno de ellos, es la cobertura de la dependencia de las personas mayores, entendiendo por dependencia, la necesidad de ayuda para realizar las tareas básicas de la vida diaria. España se encuentra en la actualidad en plena discusión parlamentaria para regular mediante ley la dependencia y cubrir el avance de este problema que en los próximos años se verá agravado por nuestra evolución demográfica y social. Esta ley pretende establecer las bases para su atención mediante un seguro de dependencia, bien de cobertura pública por parte del Estado o bien por aseguradoras privadas. El trabajo presentado en este congreso forma parte de un estudio amplio sobre la dependencia en España y abordará una aproximación a la formulación actuarial de un seguro de dependencia partiendo del uso de cadenas de Markov para un modelo de múltiples estados, y un acercamiento a la aplicación práctica mediante el análisis de datos sobre discapacidad de nuestro país.

    有序状态的联合寿险依赖于多个被保险人的死亡顺序,与一般的联合寿险相比具有一定的复杂性.本文研究联合生命保险中有序条件的复合状态寿险精算函数,对利率采用反射Brownian运动和Poisson过程的双随机模型及死亡均匀分布假设下的一种联合投保有序条件的复合状态建模,给出了生命年金、保险金、纯保费精算现值及保险金的二阶矩的表达式.运用这些表达式可以对联合投保有序状态的保险损失风险进行分析.%Joint life insurance of orderly compound status depends on the death order of the insured persons. As compared with the general insurances, it is of more complexity to a certain extent. This paper investigates the actuarial function of joint life insurance of orderly compound status. Both reflected standard Brownian motion and Possion process are used to model the stochastic interest rates and further it is employed to construct the actuarial model. The formulas of joint life insurance of compound status are proposed, including the life annuities, insurance, actuarial present value of net premiums and second moments of insurance. Based on the formulas so proposed, the loss risk of the joint life insurance of orderly compound status can reasonably be analyzed.

  10. Actuarial considerations on genetic testing.

    Le Grys, D J

    1997-08-29

    In the UK the majority of life insurers employ relatively liberal underwriting standards so that people can easily gain access to life assurance cover. Up to 95% of applicants are accepted at standard terms. If genetic testing becomes widespread then the buying habits of the public may change. Proportionately more people with a predisposition to major types of disease may take life assurance cover while people with no predisposition may take proportionately less. A model is used to show the possible effect. However, the time-scales are long and the mortality of assured people is steadily improving. The change in buying habits may result in the rate of improvement slowing down. In the whole population, the improvement in mortality is likely to continue and could improve faster if widespread genetic testing results in earlier diagnosis and treatment. Life insurers would not call for genetic tests and need not see the results of previous tests except for very large sums assured. In the UK, life insurers are unlikely to change their underwriting standards, and are extremely unlikely to bring in basic premium rating systems that give discounts on the premium or penalty points according to peoples genetic profile. The implications of widespread genetic testing on medical insurance and some health insurance covers may be more extreme.

    反向抵押贷款是应对养老问题的一个创新模式。本文为改进传统反向抵押贷款定价模型必须建立在固定利率基础之上的缺点,利用Wiener过程和负二项分布对利息力积累函数进行联合建模,构建了随机利率下的反向抵押贷款精算定价模型及死亡均匀分布(UDD)假设下随机利率反向抵押贷款精算定价模型。最后,本文运用Matlab软件对随机利率下精算定价模型进行数值测算,比较了不同参数的变化对贷款额的影响程度,得到随机利率下的反向抵押贷款精算定价模型对借款人具有一定的吸引力、贷款利率较房产价值年均升值率和房产折旧率更敏感、递增年金模型受贷款利率变动影响较小等结论。上述结论为我国反向抵押贷款的政策制定与定价提供了一定的理论依据。%The reverse mortgage is a creative measure to support the aged people. for improving shortcomings that the traditional reverse mortgage loan pricing model must be established on the basis of fixed interest rate, this paper builds the united model of accumulation function of interest force by process and negative-binomial distribution, and constructs reverse mortgages actuarial pricing model under the stochastic interest rate and the stochastic interest rate reverse actuarial pricing model under UDD assumption. Finally, this paper uses the Matlab software to change different parameters of actuarial pricing model under stochastic interest rate influence on the degree of the loan, it is concluded that the conclusion of the model is in line with the actual situation, therefore, it has important practical significance to study stochastic interest rate reverse mortgage loan pricing model.

    随着我国人口老年化问题的日趋加剧,养老金计划对于老年人口的生活保障愈显得重要。寿险精算理论在科学合理制定保险产品价格方面至关重要。利率是影响价格的最重要因素之一。从长期来看,利率随时间的变化而波动,具有很强的随机波动性。文章考虑利用具有随机波动特性的CIR利率模型,建立养老金多元衰减模型,进而获得延期年金的精算现值解析式。%With the problem of astogeny getting worse,pension schemes are even more vital to the liv⁃ing security of the old.

In the long run, the rate of interest fluctuates with time going by, enjoying strong and random volatility. To establish the multiple attenuation pattern of pension, the authors consider using the pattern of the rate of interest characterized by random and fluctuant CIR,and then gain the formu⁃la of actuarial present value of deferred annuity.

    人口老龄化的加剧可能会恶化我国城镇职工医疗保险制度的财务状况。文章在相关参数假设的基础上通过精算模型评估发现,虽然城镇职工医疗保险个人账户累计余额逐年增加,但是在2025年统筹基金将会收不抵支,收支差为-102.11亿元,这一差值还会逐年扩大,至2033年累计结余会使用完毕。针对以上状况,文章在评估了几种改善统筹基金财务状况的政策方案后发现,个人账户与统筹基金合并能将收不抵支和出现赤字的年份推迟到2034年和2046年,这一方案优于其他方案。%The increasing population aging may worsen the financial sit uation of China's urban resident basic medical insurance system. Based on the hypothesis of related parameters and the actuarial evaluation models, this paper finds that the accumulated amount of the urban resident medical sav ings accounts increases year by year, but the income of the pooling fund will not balance the expense in 2025; the gap between income and expenditure is -10. 211 billion yuan and as the gap will gradually widen, the accumulated amount of the pooling fund will be used up in 2033. After evaluating some policy options of improving the financial status of the pooling fund, this pa per shows that the integration of individual medical savings accounts and pooling fund can postpone the time of income over expenditure until 2034 and the time of deficit until 2046, so it is better than other policy options.

    Full Text Available Renal transplantation is the treatment of choice for patients suffering end-stage renal disease, but as the long-term renal allograft survival is limited, most transplant recipients will face graft loss and will be considered for a retransplantation. The goal of this study was to evaluate the patient and graft survival of the 61 renal transplant recipients after second or subsequent renal transplantation, transplanted in our institution between 1990 and 2010, and to identify risk factors related to inferior outcomes. Actuarial patient survival was 98.3%, 94.8%, and 88.2% after one, three, and five years, respectively. Actuarial graft survival was 86.8%, 80%, and 78.1% after one, three, and five years, respectively. Risk-adjusted analysis revealed that only age at the time of last transplantation had a significant influence on patient survival, whereas graft survival was influenced by multiple immunological and surgical factors, such as the number of HLA mismatches, the type of immunosuppression, the number of surgical complications, need of reoperation, primary graft nonfunction, and acute rejection episodes. In conclusion, third and subsequent renal transplantation constitute a valid therapeutic option, but inferior outcomes should be expected among elderly patients, hyperimmunized recipients, and recipients with multiple operations at the site of last renal transplantation.

    Kulkarni, V G

    2011-01-01

    This is an introductory-level text on stochastic modeling. It is suited for undergraduate students in engineering, operations research, statistics, mathematics, actuarial science, business management, computer science, and public policy. It employs a large number of examples to teach the students to use stochastic models of real-life systems to predict their performance, and use this analysis to design better systems. The book is devoted to the study of important classes of stochastic processes: discrete and continuous time Markov processes, Poisson processes, renewal and regenerative processes, semi-Markov processes, queueing models, and diffusion processes. The book systematically studies the short-term and the long-term behavior, cost/reward models, and first passage times. All the material is illustrated with many examples, and case studies. The book provides a concise review of probability in the appendix. The book emphasizes numerical answers to the problems. A collection of MATLAB programs to accompany...

    河北省被征地农民基本养老保险制度自2005年颁布以来,根据缴费方式及待遇领取的不同,可以将其分为“精算型”被征地农民养老保险制度和“低保型”被征地农民养老保险制度。根据这两种制度缴费方式及养老金待遇调整的特点,构建了两种制度下养老保险替代率的精算模型,结合灰色预测模型GM(1,1)及计量经济学的原理对相关数据进行处理,并分别用石家庄市和秦皇岛市数据进行两种精算模型的实证分析,得出从长期看“低保型”被征地农民保险制度设计的养老金替代率水平要高于“精算型”的替代率的结论,根据模型分析结果给出结论及相关建议。%Since the pension of security system for land-expropriatod peasants in Hebei province has been promulgate in 2005, according to the diversity of paying the fee and receiving pension, it can be divided into "Actuarial-Type" and "Minimum Standard Type" of the pension of security system for land-expropriated peasants. This paper builds the replacement rate of pension actuarial model under the two systems. Combining the gray prediction model GM ( 1, 1 ) and econometric knowledge of the relevant data processing, and using actuarial data for empirical analysis of the mod- el in Shijiazhuang and Qinhuangdao City, it has been concluded that from the long term, "actuarial-type" system for land-exprepriated peasants is lower than "Minimum Standard Type" of the replacement rate of the conclusions. Final- ly, the paper gives conclusions and recommendations according to the model analysis.

  3. Survivorship analysis of pedicle spinal instrumentation.

    McAfee, P C; Weiland, D J; Carlow, J J

    1991-08-01

    Between 1985 and 1989, the senior author performed 120 consecutive pedicle instrumentation cases--78 Steffee (VSP) procedures and 42 procedures using Cotrel-Dubousset instrumentation. Posterolateral or posterior fusions using autogenous iliac bone graft were performed across the instrumented vertebrae in all cases. Survivorship analysis was used to calculate a predicted cumulative rate of success for this series of patients over 10 years postoperative follow-up. The criteria of failure of pedicular instrumentation or "death" of an implant were defined as 1) screw bending, 2) screw breakage, 3) infection, 4) loosening of implants, 5) any rod or plate hardware problems, or 6) removal of hardware due to a neurologic complication. Out of 526 pedicle screws (175 Cotrel-Dubousset screws, 351 VSP screws) there were 22 problem screws (22/526 = 4.18%). Six screws had bent, none were infected, 16 screws had broken, and none were loose. The 22 problem screw events occurred in 12 patients. In seven patients, the instrumentation failure was an incidental radiographic finding, in that patients had a solid posterolateral fusion. The remaining five patients had screw breakage in association with a pseudarthrosis. Life table calculations predicted the survivorship of instrumentation without complications would be 80% at 10 years postoperative follow-up. Actuarial analysis predicted the survivorship of solid posterolateral fusion at 90% at 10 years follow-up. This survivorship rate is similar to those predicted at 10 years follow-up for other more widely used orthopedic surgical implants such as total hip arthroplasty components.

  4. Analysis

    Maurin, Krzysztof

    1980-01-01

    The extraordinarily rapid advances made in mathematics since World War II have resulted in analysis becoming an enormous organism spread­ ing in all directions. Gone for good surely are the days of the great French "courses of analysis" which embodied the whole of the "ana­ lytical" knowledge of the times in three volumes-as the classical work of Camille Jordan. Perhaps that is why present-day textbooks of anal­ ysis are disproportionately modest relative to the present state of the art. More: they have "retreated" to the state before Jordan and Goursat. In recent years the scene has been changing rapidly: Jean Dieudon­ ne is offering us his monumentel Elements d'Analyse (10 volumes) written in the spirit of the great French Course d'Analyse. To the best of my knowledge, the present book is the only one of its size: starting from scratch-from rational numbers, to be precise-it goes on to the theory of distributions, direct integrals, analysis on com­ plex manifolds, Kahler manifolds, the theory of sheave...

    Ar Rika fault zone constitutes one of the two major parts of the NW-SE Najd fault system (NFS), which is one of the most prominent structural features located in the east of the center of the Arabian Shield, Saudi Arabia. By using Enhancement Thematic Mapper data (ETM+) and Principle Component Analysis (PCA), surface geological characteristics, distribution of rock types, and the different trends of linear features and faults are determined in the study area. First and second order magnetic gradients of the geomagnetic field at the North East of Wadi Ar Rika have been calculated in the frequency domain to map both surface and subsurface lineaments and faults. Lineaments as deduced from previous studies, suggest an extension of the NFS beneath the cover rocks in the study area. In the present study, integration of magnetic gradients and remote sensing analysis that resulted in different valuable derivative maps confirm the subsurface extension of some of the surface features. The 3D Euler deconvolution, the total gradient, and the tilt angle maps have been utilized to determine accurately the distribution of shear zones, the tectonic implications, and the internal structures of the terranes in the Ar Rika quadrangle in three dimensions.

  6. Hazard function analysis for flood planning under nonstationarity

    Read, Laura K.; Vogel, Richard M.

    2016-05-01

    The field of hazard function analysis (HFA) involves a probabilistic assessment of the "time to failure" or "return period," T, of an event of interest. HFA is used in epidemiology, manufacturing, medicine, actuarial statistics, reliability engineering, economics, and elsewhere. For a stationary process, the probability distribution function (pdf) of the return period always follows an exponential distribution, the same is not true for nonstationary processes. When the process of interest, X, exhibits nonstationary behavior, HFA can provide a complementary approach to risk analysis with analytical tools particularly useful for hydrological applications. After a general introduction to HFA, we describe a new mathematical linkage between the magnitude of the flood event, X, and its return period, T, for nonstationary processes. We derive the probabilistic properties of T for a nonstationary one-parameter exponential model of X, and then use both Monte-Carlo simulation and HFA to generalize the behavior of T when X arises from a nonstationary two-parameter lognormal distribution. For this case, our findings suggest that a two-parameter Weibull distribution provides a reasonable approximation for the pdf of T. We document how HFA can provide an alternative approach to characterize the probabilistic properties of both nonstationary flood series and the resulting pdf of T.

    2014-01-01

    There are many problems existing in the basic endowment insurance system of enterprise employees, which show no fairness nor sustainability. And if no actions are taken,the goal of basic pension’s national co-ordination would not be fully realized. With the principle of actuarial balance between the fees and pension benefits,the existing system must go through effective reform. We should insist freemasonry and incentive coexistence and reform the approaches of the original pension which is linked to employees’average wages. With the average life expectancy at retirement as a divisor,taking into account Masonic life factors,we should reform the basic pension approach which is linked to individual indexation wages. Also,using retirement and post-retirement average expectancy as a divisor,we shall improve the approach of personal accounts pension to establish a pension mechanism which connects with contributions and retirement age. Furthermore,a stable pension adjustment mechanism linked with wages’growth should also be built to achieve the goal of pension national co-ordination in a fair and sustainable system.%现行企业职工基本养老保险制度存在许多问题,不公平也不可持续,不改革实现基础养老金全国统筹。在缴费和领取养老金待遇精算平衡的原则下,必须对现行制度进行有效改革。坚持共济与激励共存,以“超额累退”算法改革原来与在岗职工平均工资挂钩的基础养老金计发办法;以退休时的平均预期余命为除数,同时考虑生命共济因素,改革与个人指数化平均缴费工资挂钩的基础养老金计发办法;以退休时和退休后每年的平均预期余命为除数,改革个人账户养老金计发办法,建立养老金与缴费贡献和退休年龄密切相关的联系机制。此外要建立与工资增长挂钩的稳定的养老金调整机制,在公平可持续的制度下实现基础养老金全国统筹。

    1997-03-01

    Forty-three patients with the unilateral type of acoustic neurinoma treated by gamma knife radiosurgery were evaluated from the viewpoint of functional preservation of cranial nerves and complications. The follow-up period ranged from 22 to 55 months (mean 36 months). The tumors, which ranged in volume from 0.1 to 18.7 ml (mean 4.0 ml), were treated with marginal radiation doses of 9-15 Gy (mean 13.4 Gy) with multiple isocenters (mean 8.7). Functional hearing was preserved in 80% of patients, and actuarial hearing preservation rates were 83% at 1 year, 77% at 2 years, and 77% at 3 years after gamma knife radiosurgery. No factor was found to correlate with hearing deterioration using Cox`s proportional hazards regression model. Transient facial and trigeminal neuropathies occurred in 2.3% and 4.7% of patients, respectively. Ten patients (23%) experienced transient dizziness 3 to 6 months after radiosurgery, but only preradiosurgery canal palsy was found to correlate with this using multiple regression analysis (p=0.02). Three patients developed communicating hydrocephalus, which may have been due to the high cerebrospinal fluid protein concentration (mean 149 mg/dl). Our results show that gamma knife radiosurgery should be considered as alternative therapy for patients with small-to medium-sized acoustic neurinomas, especially in those with functional hearing, due to the high cranial nerve function preservation rates achieved with this procedure.

  16. CLUSTER ANALYSIS OF NATURAL DISASTER LOSSES IN POLISH AGRICULTURE

    Grzegorz STRUPCZEWSKI

    2015-04-01

    Full Text Available Agricultural production risk is of special nature due to a great number of hazards, relative weakness of production entities on the market and high ambiguity which is greater than in industrial production. Natural disasters occurring very frequently, at simultaneous low percentage of insured farmers, cause damage of such sizes that force the state to organise current financial aid (for instance in the form of preferential natural disaster loans. This aid is usually not sufficient. On the other hand, regional diversity of the risk level does not positively affect the development of insurance. From the perspective of insurance companies and policymakers it becomes highly important to investigate the spatial structure of losses in agriculture caused by natural disasters. The purpose of the research is to classify the 16 Polish voivodeships into clusters in order to show differences between them according to the criterion of level of damage in agricultural farms caused by natural disasters. On the basis of the cluster analysis it was demonstrated that 11 voivodeships form quite a homogeneous group in terms of size of damage in agriculture (the value of damage in cultivations and the acreage of destroyed cultivations are two most important factors determining affiliation to the cluster, however, the profile of loss occurring in other five voivodeships has a very individual course and requires separate handling in the actuarial sense. It was also proved that high value of losses in agriculture in the absolute sense in given voivodeships do not have to mean high vulnerability of agricultural farms from these voivodeships to natural risks.

    Conditional survival (CS), the survival beyond a pre-defined time interval, can identify periods of higher mortality risk for patients with locally advanced laryngeal cancer who face treatment-related toxicity and comorbidities related to alcohol and smoking in the survivorship setting. Using Weibull regression modeling, we analyzed retrospectively abstracted data from 638 records of patients who received radiation to identify prognostic factors for overall survival (OS) and recurrence free survival (RFS) for the first 3 years of survival and for OS conditional upon 3 years of survival. The CS was iteratively calculated, stratifying on variables that were statistically significant on multivariate regression. Predictive nomograms were generated. The median total follow up time was 175 months. The 3- and 6- year actuarial overall survival (OS) was 68% (95% confidence interval [CI] 65–72%) and 49% (CI 45–53%). The 3-year conditional overall survival (COS) at 3 years was 72% (CI 65–74%). Black patients had worse COS over time. Nodal disease was significantly associated with recurrence, but after 3 years, the 3-year conditional RFS converged for all nodal groups. In conclusion, the CS analysis in this patient cohort identified subgroups and time intervals that may represent opportunities for intervention. PMID:28276466

    McCarthy, Mac

    2015-01-01

    In 2008, the Institute for Healthcare Improvement (IHI) promulgated the Triple Aim, which advocates simultaneous improvements in patient experiences, improved population health and lower cost per capita. In 2010, the Patient Protection and Affordable Care Act (ACA) promised quality, affordable health care for all Americans. It's fair to assume that the framers of ACA were aware of the Triple Aim, and it is likely that much of ACA was heavily influenced by IHI's positions. So it is reasonable, from time to time, to assess ACA's impact on health care against the Triple Aim principles.

    The German Insurance Association (GDV) analyzed the impacts of climate change for the German insurance market. The work was conducted in cooperation with Potsdam Institute for Climate Impact Research, Freie Universität Berlin and University of Cologne. Different approaches and data sets were used to analyze the impacts of winter storm, hail and floods. High-resolution loss records to residential buildings in Germany were provided. These daily records are available on a fine spatial level of administrative districts from 1997-2007. For the period of 1984-2008 daily losses to residential buildings were derived from motor vehicle own damage insurance, which shows a surprisingly high correlation between building losses and motor vehicle losses caused by natural hazards. Loss functions from GDVs own flood risk model were made available to estimate flood losses. As climate change will progress the mean annual losses in the private residential building insurance might increase. Until 2100 losses due to winter storm could rise by more than 50%. The increase is mainly attributable to the intensification of individual exceptionally severe storms. Climate change will also result in an increase of flood losses. By the end of the century mean losses are expected to be twice as high - depending on the given scenario they could remain constant or triple. Conversely extreme events with high cumulative losses are expected to become significantly more frequent. Storms with a today's return period of 50 years might occur every 10 years at the end of the century. Floods, now returning every 50 years, could arise every 25 years. For the first time hailstorms have been analyzed. It was noticed, that in particular East Germany might be hit more frequently. Despite these findings, i.e. the cost of insurance against natural hazards might increase, the extent of such an increase in Germany should still remain within limits that can be mastered by the insurance companies. But we have to adapt to climate change. For this purpose stakeholder usually need ascertained numbers. Because our results were achieved using ensemble techniques they display per se a considerable spread. Despite this fact our results are robust over all approaches and climate models. Therefore they can be used for strategic decisions, less for daily routine business. Higher and more frequent losses will require higher venture capital and must be taken into account when implementing the EU directive Solvency II. If we assess our results carefully and act farseeing, we will be able to draw from manifold activities to deal with climate change impacts. Smart portfolio policy can help to reduce risks. Working with limits and franchises can help to insure highly exposed risks. Therefore GDV offers to his member companies wide accepted tools and risk models such as ZÜRS Geo, HQ Kumul and detailed risk statistics. After all, well-directed information policy, increased risk awareness and preventive action can reduce climate change impacts significantly.

    Full Text Available CONTEXT AND AIM: The prognosis of primary gliosarcoma (PGS remains dismal with current treatment modalities. We analyzed the outcome of PGS patients treated with concurrent and adjuvant temozolomide (TMZ. SETTINGS AND DESIGN: Retrospective single institutional analysis. MATERIALS AND METHODS: We retrospectively evaluated 27 patients of PGS treated with radiotherapy (RT and TMZ during 2007-2012. STATISTICAL ANALYSIS USED: Overall survival (OS was estimated by the use of Kaplan Meier method and toxicities were evaluate using common terminology criteria for adverse events version 2.0 (National Cancer Institute, USA. RESULTS: Median age at presentation and Karnofsky performance status was 45 years and 90 respectively and male: female ratio was 20:7. Patients received adjuvant RT to a total dose of 60 Gy at 2 Gy/fraction. All patients except 5 received adjuvant TMZ to a median number of 6 cycles. Grade 2 and 3 hematological toxicity was seen in 8% and 4% of patients respectively during concurrent RT. During adjuvant chemotherapy, 13.6% had Grade 3 thrombocytopenia and 9.5% had Grade 3 neutropenia. Median OS was 16.7 months (1 year and 2 year actuarial OS was 70.8% and 32.6% respectively. Adjuvant TMZ was associated with a better survival (median survival 21.21 vs. 11.93 months; P = 0.0046 on univariate analysis and also on multivariate analysis (hazard ratio 1.82, 95% confidence interval: 1.503-25.58; P = 0.012. CONCLUSIONS: The results of our study, largest series of patients with PGS treated with concurrent and adjuvant TMZ shows an impressive survival with acceptable toxicity. We suggest TMZ be included in the “standard of care” for this tumor.

  8. Exposure-response analysis of risk of respiratory disease associated with occupational exposure to chrysotile asbestos.

    Stayner, L; Smith, R; Bailer, J; Gilbert, S; Steenland, K; Dement, J; Brown, D; Lemen, R

    1997-01-01

    OBJECTIVES: To evaluate alternative models and estimate risk of mortality from lung cancer and asbestosis after occupational exposure to chrysotile asbestos. METHODS: Data were used from a recent update of a cohort mortality study of workers in a South Carolina textile factory. Alternative exposure-response models were evaluated with Poisson regression. A model designed to evaluate evidence of a threshold response was also fitted. Lifetime risks of lung cancer and asbestosis were estimated with an actuarial approach that accounts for competing causes of death. RESULTS: A highly significant exposure-response relation was found for both lung cancer and asbestosis. The exposure-response relation for lung cancer seemed to be linear on a multiplicative scale, which is consistent with previous analyses of lung cancer and exposure to asbestos. In contrast, the exposure-response relation for asbestosis seemed to be nonlinear on a multiplicative scale in this analysis. There was no significant evidence for a threshold in models of either the lung cancer or asbestosis. The excess lifetime risk for white men exposed for 45 years at the recently revised OSHA standard of 0.1 fibre/ml was predicted to be about 5/1000 for lung cancer, and 2/1000 for asbestosis. CONCLUSIONS: This study confirms the findings from previous investigations of a strong exposure-response relation between exposure to chrysotile asbestos and mortality from lung cancer, and asbestosis. The risk estimates for lung cancer derived from this analysis are higher than those derived from other populations exposed to chrysotile asbestos. Possible reasons for this discrepancy are discussed.

    2014-05-01

    Background and Purpose: Brachytherapy in the treatment of locally advanced cervical cancer has changed substantially because of the introduction of combined intracavitary/interstitial applicators and an adaptive target concept, which is the focus of the prospective, multi-institutional EMBRACE study ( (www.embracestudy.dk)) on image-guided adaptive brachytherapy (IGABT). So far, little has been reported about the development of early to late vaginal morbidity in the frame of IGABT. Therefore, the aim of the present EMBRACE analysis was to evaluate the manifestation pattern of vaginal morbidity during the first 2 years of follow-up. Methods and Materials: In total, 588 patients with a median follow-up time of 15 months and information on vaginal morbidity were included. Morbidity was prospectively assessed at baseline, every 3 months during the first year, and every 6 months in the second year according to the Common Terminology Criteria for Adverse Events, version 3, regarding vaginal stenosis, dryness, mucositis, bleeding, fistula, and other symptoms. Crude incidence rates, actuarial probabilities, and prevalence rates were analyzed. Results: At 2 years, the actuarial probability of severe vaginal morbidity (grade ≥3) was 3.6%. However, mild and moderate vaginal symptoms were still pronounced (grade ≥1, 89%; grade ≥2, 29%), of which the majority developed within 6 months. Stenosis was most frequently observed, followed by vaginal dryness. Vaginal bleeding and mucositis were mainly mild and infrequently reported. Conclusion: Severe vaginal morbidity within the first 2 years after definitive radiation (chemo)therapy including IGABT with intracavitary/interstitial techniques for locally advanced cervical cancer is limited and is significantly less than has been reported from earlier studies. Thus, the new adaptive target concept seems to be a safe treatment with regard to the vagina being an organ at risk. However, mild to moderate vaginal morbidity

    Full Text Available To analyze the clinical features and prognostic factors associated with the survival of patients with a very rare occurrence of brain metastasis (BM from differentiated thyroid cancer (DTC.A total of 37 patients with DTC who were diagnosed with BM between 1995 and 2014 were included. We reviewed the clinical characteristics, treatment modalities, and image findings of BM. Factors associated with survival were evaluated, and the patients were divided into three prognostic groups (Groups A, B, and C for comparative analysis.The median age at BM was 63 years, and the median time from initial thyroid cancer diagnosis to BM was 3.8 years. The median survival and the 1-year actuarial survival rate after BM were 8.8 months and 47%, respectively. According to univariate and multivariate analyses, four good prognostic factors (GPFs were identified including age ≤ 60 years, PS ≤ ECOG 2, ≤ 3 BM sites, and without extracranial metastasis prior to BM. Three prognostic groups were designed based on age and number of remaining GPFs: patients ≤ 60 years of age with at least 2 GPFs (Group A had the most favorable prognosis with a median survival of 32.8 months; patients ≤ 60 years of age with fewer than 2 GPFs and those > 60 years of age with at least 2 GPFs (Group B had an intermediate prognosis with a median survival of 9.4 months; and patients > 60 years of age with fewer than 2 GPFs (Group C had the least favorable prognosis with a median survival of 1.5 months.The survival of patients with BM form DTC differed among the prognostic groups based on the total number of good prognostic factors.

  13. A retrospective health policy analysis of the development and implementation of the voluntary health insurance system in Lebanon: learning from failure.

    El-Jardali, Fadi; Bou-Karroum, Lama; Ataya, Nour; El-Ghali, Hana Addam; Hammoud, Rawan

    2014-12-01

    Public policymaking is complex and suffers from limited uptake of research evidence, particularly in the Eastern Mediterranean Region (EMR). In-depth case studies examining health policymaking in the EMR are lacking. This retrospective policy analysis aims at generating insights about how policies are being made, identifying factors influencing policymaking and assessing to what extent evidence is used in this process by using the Lebanese Voluntary Health Insurance policy as a case study. The study examined the policymaking process through a policy tracing technique that covered a period of 12 years. The study employed a qualitative research design using a case study approach and was conducted in two phases over the course of two years. Data was collected using multiple sources including: 1) a comprehensive and chronological media review; 2) twenty-two key informant interviews with policymakers, stakeholders, and journalists; and 3) a document review of legislations, minutes of meetings, actuarial studies, and official documents. Data was analyzed and validated using thematic analysis. Findings showed that the voluntary health insurance policy was a political decision taken by the government to tackle an urgent political problem. Evidence was not used to guide policy development and implementation and policy implementers and other stakeholders were not involved in policy development. Factors influencing policymaking were political interests, sectarianism, urgency, and values of policymakers. Barriers to the use of evidence were lack of policy-relevant research evidence, political context, personal interests, and resource constraints. Findings suggest that policymakers should be made more aware of the important role of evidence in informing public policymaking and the need for building capacity to develop, implement and evaluate policies. Study findings are likely to matter in light of the changes that are unfolding in some Arab countries and the looming

  14. Whole lot of parts: stress in extreme environments.

    Steel, G Daniel

    2005-06-01

    Stress has been a central interest for researchers of human behavior in extreme and unusual environments and also for those who are responsible for planning and carrying out expeditions involving such environments. This paper compares the actuarial and case study methods for predicting reactions to stress. Actuarial studies are useful, but do not tap enough variables to allow us to predict how a specific individual will cope with the rigors of an individual mission. Case histories provide a wealth of detail, but few investigators understand the challenges of properly applying this method. This study reviews some of the strengths and weaknesses of the actuarial and case history methods, and presents a four celled taxonomy of stress based on method (actuarial and case history) and effects (distress and eustress). For both research and operational purposes, the person, the setting, and time should not be considered independently; rather, it is an amalgam of these variables that provides the proper basis of analysis.

    Purpose: Lymph node status is an important predictor of survival in pancreatic cancer. We performed a secondary analysis of Radiation Therapy Oncology Group (RTOG) 9704, an adjuvant chemotherapy and chemoradiation trial, to determine the influence of lymph node factors-number of positive nodes (NPN), total nodes examined (TNE), and lymph node ratio (LNR ratio of NPN to TNE)-on OS and disease-free survival (DFS). Patient and Methods: Eligible patients from RTOG 9704 form the basis of this secondary analysis of lymph node parameters. Actuarial estimates for OS and DFS were calculated using Kaplan-Meier methods. Cox proportional hazards models were performed to evaluate associations of NPN, TNE, and LNR with OS and DFS. Multivariate Cox proportional hazards models were also performed. Results: There were 538 patients enrolled in the RTOG 9704 trial. Of these, 445 patients were eligible with lymph nodes removed. Overall median NPN was 1 (min-max, 0-18). Increased NPN was associated with worse OS (HR = 1.06, p = 0.001) and DFS (HR = 1.05, p = 0.01). In multivariate analyses, both NPN and TNE were associated with OS and DFS. TNE > 12, and >15 were associated with increased OS for all patients, but not for node-negative patients (n = 142). Increased LNR was associated with worse OS (HR = 1.01, p < 0.0001) and DFS (HR = 1.006, p = 0.002). Conclusion: In patients who undergo surgical resection followed by adjuvant chemoradiation, TNE, NPN, and LNR are associated with OS and DFS. This secondary analysis of a prospective, cooperative group trial supports the influence of these lymph node parameters on outcomes after surgery and adjuvant therapy using contemporary techniques.

    Purpose: To investigate local control, survival outcomes, and predictors of local relapse for patients treated with spine stereotactic body radiation therapy. Methods and Materials: We reviewed the records of 332 spinal metastases consecutively treated with stereotactic body radiation therapy between 2002 and 2012. The median follow-up for all living patients was 33 months (range, 0-111 months). Endpoints were overall survival and local control (LC); recurrences were classified as either in-field or marginal. Results: The 1-year actuarial LC and overall survival rates were 88% and 64%, respectively. Patients with local relapses had poorer dosimetric coverage of the gross tumor volume (GTV) compared with patients without recurrence (minimum dose [Dmin] biologically equivalent dose [BED] 23.9 vs 35.1 Gy, P<.001; D98 BED 41.8 vs 48.1 Gy, P=.001; D95 BED 47.2 vs 50.5 Gy, P=.004). Furthermore, patients with marginal recurrences had poorer prescription coverage of the GTV (86% vs 93%, P=.01) compared with those with in-field recurrences, potentially because of more upfront spinal canal disease (78% vs 24%, P=.001). Using a Cox regression univariate analysis, patients with a GTV BED Dmin ≥33.4 Gy (median dose) (equivalent to 14 Gy in 1 fraction) had a significantly higher 1-year LC rate (94% vs 80%, P=.001) compared with patients with a lower GTV BED Dmin; this factor was the only significant variable on multivariate Cox analysis associated with LC (P=.001, hazard ratio 0.29, 95% confidence interval 0.14-0.60) and also was the only variable significant in a separate competing risk multivariate model (P=.001, hazard ratio 0.30, 95% confidence interval 0.15-0.62). Conclusions: Stereotactic body radiation therapy offers durable control for spinal metastases, but there is a subset of patients that recur locally. Patients with local relapse had significantly poorer tumor coverage, which was likely attributable to treatment planning directives that prioritized the

    Aims and background. To describe feasibility, tolerability and clinical outcomes of stereotactic body radiation therapy (SBRT) in the treatment of adrenal metastases in 34 consecutive cancer patients. Material and methods. Between March 2004 and July 2010, a total of 34 consecutive patients, accounting for 36 adrenal metastatic lesions, were treated with SBRT. SBRT treatments were delivered by a Linac Varian 600 with microMLC (3DLine, Elekta, Stockholm, Sweden) and a Linac ELEKTA Precise (Elekta). All 34 patients were clinically and radiologically evaluated during and after completion of SBRT. Following outcomes were taken into account: best clinical response at any time, local control, time to systemic progression, time to local progression, overall survival and toxicity. Survival was estimated by the Kaplan-Meier method and factor potentially affecting outcomes were analyzed with Cox regression analysis. Results. Total RT doses ranged from 20 Gy in 4 fractions to 45 Gy in 18 fractions (median dose: 32 Gy; median number of fractions: 4). All doses were prescribed to the 95% isodose line. No cases of Grade {>=} 3 toxicity were recorded. At a median follow-up time of 41 months (range, 12-75) 22 patients were alive. Three of 28 lesions (11%) showed complete response, 13/28 (46%) partial response, 10/28 (36%) stable disease and 2/28 (7%) progressed in the treated area. Local failure was observed in 13 cases. Actuarial local control rates at one and two years were 66% and 32%, respectively. Median time to local progression was 19 months. Median survival was 22 months. Conclusion. SBRT in adrenal gland metastasis is feasible without significant acute and late toxicities, with a good rate of local control. New SBRT fractionation schemes and the possibility to combine new systemic approaches should be investigated in order to further increase local control and reduce systemic disease progression.

  4. Actuarial risk of isolated CNS involvement in Ewing's sarcoma following prophylactic cranial irradiation and intrathecal methotrexate

    Trigg, M.E.; Makuch, R.; Glaubiger, D.

    1985-04-01

    Records of 154 patients with Ewing's sarcoma treated at the National Cancer Institute were reviewed to assess the incidence and risk of developing isolated central nervous system (CNS) Ewing's sarcoma. Sixty-two of the 154 patients had received CNS irradiation and intrathecal (i.t.) methotrexate as part of their initial therapy to prevent the occurrence of isolated CNS Ewing's sarcoma. The risk of developing isolate CNS Ewing's sarcoma was greatest within the first two years after diagnosis and was approximately 10%. The overall risk of CNS recurrence in the group of patients receiving DNS treatment was similar to the group receiving no therapy directed to the CNS. The occurrence of isolated CNS involvement was not prevented by the use of CNS irradiation and i.t. methotrexate. Because of a lack of efficacy to the CNS irradiation regimen, current treatment regimens do not include therapy directed to CNS.

  10. Grey analysis

    Cable, G.D.

    1996-12-01

    Grey logic is not another name for fuzzy logic. Grey logic--also called grey analysis or grey system theory--is a new technology, a group of techniques for system analysis and modeling. Like fuzzy logic, grey logic is useful in situations with incomplete and uncertain information. Grey analysis is particularly applicable in instances with very limited data and in cases with little system knowledge or understanding. In this paper, a summary of the basic concepts of grey analysis is provided, with descriptions of its application to several classes of problems. Calculations methods are provided for grey relation analysis, and for modeling and prediction using grey methods.

    We study the political determination of the level of social long-term care insurance when voters also choose private insurance and saving amounts. Agents differ in income, probability of becoming dependent and of receiving family help. Social insurance redistributes across income and risk levels, while private insurance is actuarially fair. The income-to-risk ratio of agents determines whether they prefer social or private insurance. Family support crowds out the demand for both social and, e...

  10. Numerical analysis

    Jacques, Ian

    1987-01-01

    This book is primarily intended for undergraduates in mathematics, the physical sciences and engineering. It introduces students to most of the techniques forming the core component of courses in numerical analysis. The text is divided into eight chapters which are largely self-contained. However, with a subject as intricately woven as mathematics, there is inevitably some interdependence between them. The level of difficulty varies and, although emphasis is firmly placed on the methods themselves rather than their analysis, we have not hesitated to include theoretical material when we consider it to be sufficiently interesting. However, it should be possible to omit those parts that do seem daunting while still being able to follow the worked examples and to tackle the exercises accompanying each section. Familiarity with the basic results of analysis and linear algebra is assumed since these are normally taught in first courses on mathematical methods. For reference purposes a list of theorems used in the t...

  12. Complex analysis

    Freitag, Eberhard

    2005-01-01

    The guiding principle of this presentation of ``Classical Complex Analysis'' is to proceed as quickly as possible to the central results while using a small number of notions and concepts from other fields. Thus the prerequisites for understanding this book are minimal; only elementary facts of calculus and algebra are required. The first four chapters cover the essential core of complex analysis: - differentiation in C (including elementary facts about conformal mappings) - integration in C (including complex line integrals, Cauchy's Integral Theorem, and the Integral Formulas) - sequences and series of analytic functions, (isolated) singularities, Laurent series, calculus of residues - construction of analytic functions: the gamma function, Weierstrass' Factorization Theorem, Mittag-Leffler Partial Fraction Decomposition, and -as a particular highlight- the Riemann Mapping Theorem, which characterizes the simply connected domains in C. Further topics included are: - the theory of elliptic functions based on...

  13. CMB Analysis

    Bond, J R; Crittenden, Robert G.

    2001-01-01

    We describe the subject of Cosmic Microwave Background (CMB) analysis - its past, present and future. The theory of Gaussian primary anisotropies, those arising from linear physics operating in the early Universe, is in reasonably good shape so the focus has shifted to the statistical pipeline which confronts the data with the theory: mapping, filtering, comparing, cleaning, compressing, forecasting, estimating. There have been many algorithmic advances in the analysis pipeline in recent years, but still more are needed for the forecasts of high precision cosmic parameter estimation to be realized. For secondary anisotropies, those arising once nonlinearity develops, the computational state of the art currently needs effort in all the areas: the Sunyaev-Zeldovich effect, inhomogeneous reionization, gravitational lensing, the Rees-Sciama effect, dusty galaxies. We use the Sunyaev-Zeldovich example to illustrate the issues. The direct interface with observations for these non-Gaussian signals is much more compl...

    None

    1980-06-01

    The Energy Policy and Conservation Act (EPCA) mandated that minimum energy efficiency standards be established for classes of refrigerators and refrigerator-freezers, freezers, clothes dryers, water heaters, room air conditioners, home heating equipment, kitchen ranges and ovens, central air conditioners, and furnaces. EPCA requires that standards be designed to achieve the maximum improvement in energy efficiency that is technologically feasible and economically justified. Following the introductory chapter, Chapter Two describes the methodology used in the economic analysis and its relationship to legislative criteria for consumer product efficiency assessment; details how the CPES Value Model systematically compared and evaluated the economic impacts of regulation on the consumer, manufacturer and Nation. Chapter Three briefly displays the results of the analysis and lists the proposed performance standards by product class. Chapter Four describes the reasons for developing a baseline forecast, characterizes the baseline scenario from which regulatory impacts were calculated and summarizes the primary models, data sources and assumptions used in the baseline formulations. Chapter Five summarizes the methodology used to calculate regulatory impacts; describes the impacts of energy performance standards relative to the baseline discussed in Chapter Four. Also discussed are regional standards and other program alternatives to performance standards. Chapter Six describes the procedure for balancing consumer, manufacturer, and national impacts to select standard levels. Details of models and data bases used in the analysis are included in Appendices A through K.

    2006-01-01

    The use of vectors not only simplifies treatments of differential geometry, mechanics, hydrodynamics, and electrodynamics, but also makes mathematical and physical concepts more tangible and easy to grasp. This text for undergraduates was designed as a short introductory course to give students the tools of vector algebra and calculus, as well as a brief glimpse into these subjects' manifold applications. The applications are developed to the extent that the uses of the potential function, both scalar and vector, are fully illustrated. Moreover, the basic postulates of vector analysis are brou

      As the development of the global communication all over the world, English has become the international language for the global communication. Furthermore, speaking as a skill in English language learning becomes more and more important. As it is known, spoken English has specific features, thus to gain an explicit understanding of the features data analysis is helpful. Moreover it is useful for language teacher to make development in teaching to satisfy learner’s needs. Grammatical and phonological are the two remarkable aspects and specific features in spoken language therefore to discover elements into these aspects seems helpful to teaching spoken Enlgish.

    In 1943, while in charge of Columbia University's Statistical Research Group, Abraham Wald devised Sequential Design, an innovative statistical inference system. Because the decision to terminate an experiment is not predetermined, sequential analysis can arrive at a decision much sooner and with substantially fewer observations than equally reliable test procedures based on a predetermined number of observations. The system's immense value was immediately recognized, and its use was restricted to wartime research and procedures. In 1945, it was released to the public and has since revolutio

  6. Understanding analysis

    Abbott, Stephen

    2015-01-01

    This lively introductory text exposes the student to the rewards of a rigorous study of functions of a real variable. In each chapter, informal discussions of questions that give analysis its inherent fascination are followed by precise, but not overly formal, developments of the techniques needed to make sense of them. By focusing on the unifying themes of approximation and the resolution of paradoxes that arise in the transition from the finite to the infinite, the text turns what could be a daunting cascade of definitions and theorems into a coherent and engaging progression of ideas. Acutely aware of the need for rigor, the student is much better prepared to understand what constitutes a proper mathematical proof and how to write one. Fifteen years of classroom experience with the first edition of Understanding Analysis have solidified and refined the central narrative of the second edition. Roughly 150 new exercises join a selection of the best exercises from the first edition, and three more project-sty...

    2013-04-01

    Purpose: To determine whether the American Society for Radiation Oncology (ASTRO) Consensus Statement (CS) recommendations for accelerated partial breast irradiation (APBI) are associated with significantly different outcomes in a pooled analysis from William Beaumont Hospital (WBH) and the American Society of Breast Surgeons (ASBrS) MammoSite® Registry Trial. Methods and Materials: APBI was used to treat 2127 cases of early-stage breast cancer (WBH, n=678; ASBrS, n=1449). Three forms of APBI were used at WBH (interstitial, n=221; balloon-based, n=255; or 3-dimensional conformal radiation therapy, n=206), whereas all Registry Trial patients received balloon-based brachytherapy. Patients were divided according to the ASTRO CS into suitable (n=661, 36.5%), cautionary (n=850, 46.9%), and unsuitable (n=302, 16.7%) categories. Tumor characteristics and clinical outcomes were analyzed according to CS group. Results: The median age was 65 years (range, 32-94 years), and the median tumor size was 10.0 mm (range, 0-45 mm). The median follow-up time was 60.6 months. The WBH cohort had more node-positive disease (6.9% vs 2.6%, P<.01) and cautionary patients (49.5% vs 41.8%, P=.06). The 5-year actuarial ipsilateral breast tumor recurrence (IBTR), regional nodal failure (RNF), and distant metastasis (DM) for the whole cohort were 2.8%, 0.6%, 1.6%. The rate of IBTR was not statistically higher between suitable (2.5%), cautionary (3.3%), or unsuitable (4.6%) patients (P=.20). The nonsignificant increase in IBTR for the cautionary and unsuitable categories was due to increased elsewhere failures and new primaries (P=.04), not tumor bed recurrence (P=.93). Conclusions: Excellent outcomes after breast-conserving surgery and APBI were seen in our pooled analysis. The current ASTRO CS guidelines did not adequately differentiate patients at an increased risk of IBTR or tumor bed failure in this large patient cohort.

  17. Permanent interstitial low-dose-rate brachytherapy for patients with low risk prostate cancer. An interim analysis of 312 cases

    Badakhshi, Harun; Graf, Reinhold; Budach, Volker; Wust, Peter [University Hospital Berlin, Department for Radiation Oncology of Charite School of Medicine, Berlin (Germany)

    2015-04-01

    The biochemical relapse-free survival (bRFS) rate after treatment with permanent iodine-125 seed implantation (PSI) or combined seeds and external beam radiotherapy (COMB) for clinical stage T1-T2 localized prostate cancer is a clinically relevant endpoint. The goal of this work was to evaluate the influence of relevant patient- and treatment-related factors. The study population comprised 312 consecutive patients treated with permanent seed implantation. All patients were evaluable for analysis of overall survival (OS) and disease-specific survival (DSS), 230 for bRFS, of which 192 were in the PSI group and 38 in the COMB group. The prescribed minimum peripheral dose was 145 Gy for PSI, for COMB 110 Gy implant and external beam radiotherapy of 45 Gy. The median follow-up time was 33 months (range 8-66 months). bRFS was defined as a serum prostate-specific antigen (PSA) level ≤ 0.2 ng/ml at last follow-up. Overall, the actuarial bRFS at 50 months was 88.4 %. The 50-month bRFS rate for PSI and COMB was 90.9 %, and 77.2 %, respectively. In the univariate analysis, age in the categories ≤ 63 and > 63 years (p < 0.00), PSA nadir (≤ 0.5 ng/ml and > 0.5 ng/ml) and PSA bounce (yes/no) were the significant predicting factors for bRFS. None of the other patient and treatment variables (treatment modality, stage, PSA, Gleason score, risk group, number of risk factors, D90 and various other dose parameters) were found to be a statistically significant predictor of 50-month bRFS. The biochemical failure rates were low in this study. As a proof of principle, our large monocenteric analysis shows that low-dose-rate brachytherapy is an effective and safe procedure for patients with early stage prostate cancer. (orig.)

  2. Uncertainty analysis

    Thomas, R.E.

    1982-03-01

    An evaluation is made of the suitability of analytical and statistical sampling methods for making uncertainty analyses. The adjoint method is found to be well-suited for obtaining sensitivity coefficients for computer programs involving large numbers of equations and input parameters. For this purpose the Latin Hypercube Sampling method is found to be inferior to conventional experimental designs. The Latin hypercube method can be used to estimate output probability density functions, but requires supplementary rank transformations followed by stepwise regression to obtain uncertainty information on individual input parameters. A simple Cork and Bottle problem is used to illustrate the efficiency of the adjoint method relative to certain statistical sampling methods. For linear models of the form Ax=b it is shown that a complete adjoint sensitivity analysis can be made without formulating and solving the adjoint problem. This can be done either by using a special type of statistical sampling or by reformulating the primal problem and using suitable linear programming software.

  3. Matrix analysis

    Bhatia, Rajendra

    1997-01-01

    A good part of matrix theory is functional analytic in spirit. This statement can be turned around. There are many problems in operator theory, where most of the complexities and subtleties are present in the finite-dimensional case. My purpose in writing this book is to present a systematic treatment of methods that are useful in the study of such problems. This book is intended for use as a text for upper division and gradu­ ate courses. Courses based on parts of the material have been given by me at the Indian Statistical Institute and at the University of Toronto (in collaboration with Chandler Davis). The book should also be useful as a reference for research workers in linear algebra, operator theory, mathe­ matical physics and numerical analysis. A possible subtitle of this book could be Matrix Inequalities. A reader who works through the book should expect to become proficient in the art of deriving such inequalities. Other authors have compared this art to that of cutting diamonds. One first has to...

  13. Strengths and limitations of actuarial prediction of criminal reoffence in a German prison sample: a comparative study of LSI-R, HCR-20 and PCL-R.

    Dahle, Klaus-Peter

    2006-01-01

    Unlike many other countries, for many years, Germany disregarded structured instruments for assessing the risk of criminal reoffence. However, this negative attitude now seems to be gradually changing. An increasing number of contributions regarding structured instruments have been published in the German literature in the last years, and some instruments have already found their way into practice. However, studies that systematically examine the applicability of the mostly Anglo-American instruments to German criminals are still lacking. Therefore, the major objective of the current study was to test some internationally established procedures in a larger unselected sample from the German penal system. The following were included in the study: the Level of Service Inventory - Revised (LSI-R), the HCR-20 Scheme, and the Psychopathy Checklist - Revised (PCL-R). On the whole, the instruments proved to be applicable to German criminals with only a few adaptations to the German situation, and they achieved a predictive accuracy comparable to the values reported internationally. However, there were only minor differences in the predictive performance between the measures. Moreover, some basic limitations became apparent. Firstly, we found quite high percentages of criminals with medium scores and a correspondingly ambiguous prognosis. Furthermore, the predictive accuracy seemed to be dependent on demographic, criminological and psychopathological characteristics of the offenders. Finally, the instruments appeared to only partially utilize the empirical store of knowledge available regarding factors influencing the recidivism of criminals, since even a simple predictive model that only added a few further aspects besides the tested instruments (e. g. treatment yes or no) achieved systematically better predictions than the instruments alone. Altogether, the tested measures turned out to be useful instruments for risk assessments and may be conducive for a more systemized practice. However, due to the limitations inherent, they should be seen as a complement to a careful and clinically informed appraisal and not a substitute.

    Sensitivity analysis is a crucial element of rigorous engineering analysis, but performing such an analysis on a complex model is difficult and time consuming. The mission of the DART Workbench team at Sandia National Laboratories is to lower the barriers to adoption of advanced analysis tools through software integration. The integrated environment guides the engineer in the use of these integrated tools and greatly reduces the cycle time for engineering analysis.

    Tadros, A.A.M.; Tepperman, B.S.; Hryniuk, W.M.; Peters, V.G.; Rosenthal, D.; Roberts, J.T.; Path, C.B.; Figueredo, A.T.

    1983-09-01

    From 1970 to 1980, 106 patients with mycosis fungoides received total skin electron irradiation to full tolerance. The majority received 30 Gy of 3 MeV electrons in 12 treatments over three weeks. Eighty-eight patients had received prior therapy. At five years, actuarial survival is 66.7% and disease-free survival 21.4%. The median time to relapse is 12 months; prolonged survival is seen only with complete response. In advanced stages, complete response is more likely with doses over 25 Gy (80 vs 50%). First recurrences were predominently in sites of previous involvement. Death resulted mainly from extracutaneous dissemination or failure to induce remission. Complications of the therapy are discussed.

  14. Qualitative Content Analysis

    Philipp Mayring

    2000-06-01

    Full Text Available The article describes an approach of systematic, rule guided qualitative text analysis, which tries to preserve some methodological strengths of quantitative content analysis and widen them to a concept of qualitative procedure. First the development of content analysis is delineated and the basic principles are explained (units of analysis, step models, working with categories, validity and reliability. Then the central procedures of qualitative content analysis, inductive development of categories and deductive application of categories, are worked out. The possibilities of computer programs in supporting those qualitative steps of analysis are shown and the possibilities and limits of the approach are discussed. URN: urn:nbn:de:0114-fqs0002204

    De Palo, G; Kenda, R; Andreola, S; Luciani, L; Musumeci, R; Rilke, F

    1982-08-01

    From 1969 to 1977, 420 patients with endometrial carcinoma were observed and treated at the National Tumor Institute of Milan. Total abdominal hysterectomy and bilateral salpingo-oophorectomy were performed in 351. After careful clinical and pathologic review, 262 patients were classified as having stage I disease. Further treatment included post-operative radium therapy to the vaginal vault. There were 247 cases with adenocarcinoma, 10 with adenoacanthoma, and 5 with adenosquamous or clear cell carcinoma. Of 257 cases with adenocarcinoma or adenoacanthoma, 63 were grade 1, 161 grade 2, and 33 grade 3. Of the total series, only 41 cases had disease limited to the mucosal surface. The 5-year actuarial survival was 91.4% and the recurrence-free survival was 93.4%. The case material was evaluated according to the risk factors, and results were 1) premenopausal patients had a better prognosis (100% recurrence-free survival versus 92.8% for postmenopausal women, P = .003); 2) length of the uterine cavity was not a significant prognostic factor; 3) myometrial invasion alone was not prognostic but correlated with grade of tumor; 4) the grade of the tumor was an important determinant of recurrence (grade 1 98% recurrence-free survival, grade 2 95%, grade 3 79%). With the described therapy, vaginal recurrences were absent. The recurrences were distant in 20% and local with or without distant metastases in 80%.

  15. Strategic Analysis Overview

    Cirillo, William M.; Earle, Kevin D.; Goodliff, Kandyce E.; Reeves, J. D.; Stromgren, Chel; Andraschko, Mark R.; Merrill, R. Gabe

    2008-01-01

    NASA s Constellation Program employs a strategic analysis methodology in providing an integrated analysis capability of Lunar exploration scenarios and to support strategic decision-making regarding those scenarios. The strategic analysis methodology integrates the assessment of the major contributors to strategic objective satisfaction performance, affordability, and risk and captures the linkages and feedbacks between all three components. Strategic analysis supports strategic decision making by senior management through comparable analysis of alternative strategies, provision of a consistent set of high level value metrics, and the enabling of cost-benefit analysis. The tools developed to implement the strategic analysis methodology are not element design and sizing tools. Rather, these models evaluate strategic performance using predefined elements, imported into a library from expert-driven design/sizing tools or expert analysis. Specific components of the strategic analysis tool set include scenario definition, requirements generation, mission manifesting, scenario lifecycle costing, crew time analysis, objective satisfaction benefit, risk analysis, and probabilistic evaluation. Results from all components of strategic analysis are evaluated a set of pre-defined figures of merit (FOMs). These FOMs capture the high-level strategic characteristics of all scenarios and facilitate direct comparison of options. The strategic analysis methodology that is described in this paper has previously been applied to the Space Shuttle and International Space Station Programs and is now being used to support the development of the baseline Constellation Program lunar architecture. This paper will present an overview of the strategic analysis methodology and will present sample results from the application of the strategic analysis methodology to the Constellation Program lunar architecture.

    2010-04-01

    VISPA is a development environment for high energy physics analyses which enables physicists to combine graphical and textual work. A physics analysis cycle consists of prototyping, performing, and verifying the analysis. The main feature of VISPA is a multipurpose window for visual steering of analysis steps, creation of analysis templates, and browsing physics event data at different steps of an analysis. VISPA follows an experiment-independent approach and incorporates various tools for steering and controlling required in a typical analysis. Connection to different frameworks of high energy physics experiments is achieved by using different types of interfaces. We present the look-and-feel for an example physics analysis at the LHC and explain the underlying software concepts of VISPA.

  20. The ATLAS Analysis Model

    Amir Farbin

    The ATLAS Analysis Model is a continually developing vision of how to reconcile physics analysis requirements with the ATLAS offline software and computing model constraints. In the past year this vision has influenced the evolution of the ATLAS Event Data Model, the Athena software framework, and physics analysis tools. These developments, along with the October Analysis Model Workshop and the planning for CSC analyses have led to a rapid refinement of the ATLAS Analysis Model in the past few months. This article introduces some of the relevant issues and presents the current vision of the future ATLAS Analysis Model. Event Data Model The ATLAS Event Data Model (EDM) consists of several levels of details, each targeted for a specific set of tasks. For example the Event Summary Data (ESD) stores calorimeter cells and tracking system hits thereby permitting many calibration and alignment tasks, but will be only accessible at particular computing sites with potentially large latency. In contrast, the Analysis...

  3. NASA trend analysis procedures

    1993-01-01

    This publication is primarily intended for use by NASA personnel engaged in managing or implementing trend analysis programs. 'Trend analysis' refers to the observation of current activity in the context of the past in order to infer the expected level of future activity. NASA trend analysis was divided into 5 categories: problem, performance, supportability, programmatic, and reliability. Problem trend analysis uncovers multiple occurrences of historical hardware or software problems or failures in order to focus future corrective action. Performance trend analysis observes changing levels of real-time or historical flight vehicle performance parameters such as temperatures, pressures, and flow rates as compared to specification or 'safe' limits. Supportability trend analysis assesses the adequacy of the spaceflight logistics system; example indicators are repair-turn-around time and parts stockage levels. Programmatic trend analysis uses quantitative indicators to evaluate the 'health' of NASA programs of all types. Finally, reliability trend analysis attempts to evaluate the growth of system reliability based on a decreasing rate of occurrence of hardware problems over time. Procedures for conducting all five types of trend analysis are provided in this publication, prepared through the joint efforts of the NASA Trend Analysis Working Group.

  8. Fundamentals of functional analysis

    Farenick, Douglas

    2016-01-01

    This book provides a unique path for graduate or advanced undergraduate students to begin studying the rich subject of functional analysis with fewer prerequisites than is normally required. The text begins with a self-contained and highly efficient introduction to topology and measure theory, which focuses on the essential notions required for the study of functional analysis, and which are often buried within full-length overviews of the subjects. This is particularly useful for those in applied mathematics, engineering, or physics who need to have a firm grasp of functional analysis, but not necessarily some of the more abstruse aspects of topology and measure theory normally encountered. The reader is assumed to only have knowledge of basic real analysis, complex analysis, and algebra. The latter part of the text provides an outstanding treatment of Banach space theory and operator theory, covering topics not usually found together in other books on functional analysis. Written in a clear, concise manner,...

  16. Robust Sparse Analysis Regularization

    Vaiter, Samuel; Dossal, Charles; Fadili, Jalal

    2011-01-01

    This paper studies the properties of L1-analysis regularization for the resolution of linear inverse problems. Most previous works consider sparse synthesis priors where the sparsity is measured as the L1 norm of the coefficients that synthesize the signal in a given dictionary. In contrast, the more general analysis regularization minimizes the L1 norm of the correlations between the signal and the atoms in the dictionary. The corresponding variational problem includes several well-known regularizations such as the discrete total variation and the fused lasso. We first prove that a solution of analysis regularization is a piecewise affine function of the observations. Similarly, it is a piecewise affine function of the regularization parameter. This allows us to compute the degrees of freedom associated to sparse analysis estimators. Another contribution gives a sufficient condition to ensure that a signal is the unique solution of the analysis regularization when there is no noise in the observations. The s...

  17. NMA Analysis Center

    Kierulf, Halfdan Pascal; Andersen, Per Helge

    2013-01-01

    The Norwegian Mapping Authority (NMA) has during the last few years had a close cooperation with Norwegian Defence Research Establishment (FFI) in the analysis of space geodetic data using the GEOSAT software. In 2012 NMA has taken over the full responsibility for the GEOSAT software. This implies that FFI stopped being an IVS Associate Analysis Center in 2012. NMA has been an IVS Associate Analysis Center since 28 October 2010. NMA's contributions to the IVS as an Analysis Centers focus primarily on routine production of session-by-session unconstrained and consistent normal equations by GEOSAT as input to the IVS combined solution. After the recent improvements, we expect that VLBI results produced with GEOSAT will be consistent with results from the other VLBI Analysis Centers to a satisfactory level.

  18. IAC - INTEGRATED ANALYSIS CAPABILITY

    Frisch, H. P.

    1994-01-01

    The objective of the Integrated Analysis Capability (IAC) system is to provide a highly effective, interactive analysis tool for the integrated design of large structures. With the goal of supporting the unique needs of engineering analysis groups concerned with interdisciplinary problems, IAC was developed to interface programs from the fields of structures, thermodynamics, controls, and system dynamics with an executive system and database to yield a highly efficient multi-disciplinary system. Special attention is given to user requirements such as data handling and on-line assistance with operational features, and the ability to add new modules of the user's choice at a future date. IAC contains an executive system, a data base, general utilities, interfaces to various engineering programs, and a framework for building interfaces to other programs. IAC has shown itself to be effective in automatic data transfer among analysis programs. IAC 2.5, designed to be compatible as far as possible with Level 1.5, contains a major upgrade in executive and database management system capabilities, and includes interfaces to enable thermal, structures, optics, and control interaction dynamics analysis. The IAC system architecture is modular in design. 1) The executive module contains an input command processor, an extensive data management system, and driver code to execute the application modules. 2) Technical modules provide standalone computational capability as well as support for various solution paths or coupled analyses. 3) Graphics and model generation interfaces are supplied for building and viewing models. Advanced graphics capabilities are provided within particular analysis modules such as INCA and NASTRAN. 4) Interface modules provide for the required data flow between IAC and other modules. 5) User modules can be arbitrary executable programs or JCL procedures with no pre-defined relationship to IAC. 6) Special purpose modules are included, such as MIMIC (Model

  20. Gait analysis: clinical facts.

    Baker, Richard; Esquenazi, Alberto; Benedetti, Maria G; Desloovere, Kaat

    2016-08-01

    Gait analysis is a well-established tool for the quantitative assessment of gait disturbances providing functional diagnosis, assessment for treatment planning, and monitoring of disease progress. There is a large volume of literature on the research use of gait analysis, but evidence on its clinical routine use supports a favorable cost-benefit ratio in a limited number of conditions. Initially gait analysis was introduced to clinical practice to improve the management of children with cerebral palsy. However, there is good evidence to extend its use to patients with various upper motor neuron diseases, and to lower limb amputation. Thereby, the methodology for properly conducting and interpreting the exam is of paramount relevance. Appropriateness of gait analysis prescription and reliability of data obtained are required in the clinical environment. This paper provides an overview on guidelines for managing a clinical gait analysis service and on the principal clinical domains of its application: cerebral palsy, stroke, traumatic brain injury and lower limb amputation.

  1. Systems engineering and analysis

    Blanchard, Benjamin S

    2010-01-01

    For senior-level undergraduate and first and second year graduate systems engineering and related courses. A total life-cycle approach to systems and their analysis. This practical introduction to systems engineering and analysis provides the concepts, methodologies, models, and tools needed to understand and implement a total life-cycle approach to systems and their analysis. The authors focus first on the process of bringing systems into being--beginning with the identification of a need and extending that need through requirements determination, functional analysis and allocation, design synthesis, evaluation, and validation, operation and support, phase-out, and disposal. Next, the authors discuss the improvement of systems currently in being, showing that by employing the iterative process of analysis, evaluation, feedback, and modification, most systems in existence can be improved in their affordability, effectiveness, and stakeholder satisfaction.

  4. Dynamics in Epistasis Analysis.

    Awdeh, Aseel; Phenix, Hilary; Kaern, Mads; Perkins, Theodore

    2017-01-16

    Finding regulatory relationships between genes, including the direction and nature of influence between them, is a fundamental challenge in the field of molecular genetics. One classical approach to this problem is epistasis analysis. Broadly speaking, epistasis analysis infers the regulatory relationships between a pair of genes in a genetic pathway by considering the patterns of change in an observable trait resulting from single and double deletion of genes. While classical epistasis analysis has yielded deep insights on numerous genetic pathways, it is not without limitations. Here, we explore the possibility of dynamic epistasis analysis, in which, in addition to performing genetic perturbations of a pathway, we drive the pathway by a time-varying upstream signal. We explore the theoretical power of dynamical epistasis analysis by conducting an identifiability analysis of Boolean models of genetic pathways, comparing static and dynamic approaches. We find that even relatively simple input dynamics greatly increases the power of epistasis analysis to discriminate alternative network structures. Further, we explore the question of experiment design, and show that a subset of short time-varying signals, which we call dynamic primitives, allow maximum discriminative power with a reduced number of experiments.

  5. Meaning from curriculum analysis

    Finegold, Menahem; Mackeracher, Dorothy

    This paper reports on the analysis of science curricula carried out across Canada within the framework of the Second International Science Study (SISS). The organization of Canadian education in twelve autonomous educational jurisdictions is briefly described and problems are noted in relation to the analysis of curricula on a national scale. The international design for curriculum analysis is discussed and an alternative design, more suited to the diversity of science education in Canada, is introduced. The analysis of curriculum documents is described and three patterns which emerge from this analysis are identified. These derive from the concepts of commonality, specificity and prescriptiveness. Commonality relates to topics listed in curriculum guideline documents by a number of jurisdictions. Specificity refers to the richness of curriculum documents. Prescriptiveness is a measure of the extent to which jurisdictions do or do not make provision for local options in curriculum design. The Canadian analysis, using the concepts of the common curriculum, specificity and prescriptiveness, is described and research procedures are exemplified. Outcomes of curriculum analysis are presented in graphical form.

  10. Observations on risk analysis

    Thompson, W.A. Jr.

    1979-11-01

    This paper briefly describes WASH 1400 and the Lewis report. It attempts to define basic concepts such as risk and risk analysis, common mode failure, and rare event. Several probabilistic models which go beyond the WASH 1400 methodology are introduced; the common characteristic of these models is that they recognize explicitly that risk analysis is time dependent whereas WASH 1400 takes a per demand failure rate approach which obscures the important fact that accidents are time related. Further, the presentation of a realistic risk analysis should recognize that there are various risks which compete with one another for the lives of the individuals at risk. A way of doing this is suggested.

  14. Bayesian nonparametric data analysis

    Müller, Peter; Jara, Alejandro; Hanson, Tim

    2015-01-01

    This book reviews nonparametric Bayesian methods and models that have proven useful in the context of data analysis. Rather than providing an encyclopedic review of probability models, the book’s structure follows a data analysis perspective. As such, the chapters are organized by traditional data analysis problems. In selecting specific nonparametric models, simpler and more traditional models are favored over specialized ones. The discussed methods are illustrated with a wealth of examples, including applications ranging from stylized examples to case studies from recent literature. The book also includes an extensive discussion of computational methods and details on their implementation. R code for many examples is included in on-line software pages.

  15. Wood Products Analysis

    1990-01-01

    Structural Reliability Consultants' computer program creates graphic plots showing the statistical parameters of glue laminated timbers, or 'glulam.' The company president, Dr. Joseph Murphy, read in NASA Tech Briefs about work related to analysis of Space Shuttle surface tile strength performed for Johnson Space Center by Rockwell International Corporation. Analysis led to a theory of 'consistent tolerance bounds' for statistical distributions, applicable in industrial testing where statistical analysis can influence product development and use. Dr. Murphy then obtained the Tech Support Package that covers the subject in greater detail. The TSP became the basis for Dr. Murphy's computer program PC-DATA, which he is marketing commercially.

  16. [Emergy analysis of ecosystems].

    Lan, S; Qin, P

    2001-02-01

    The concept of emergy and its use for comparing with energy were discussed in this paper. Emergy was defined as the amount of available energy required directly and indirectly to make a product or services, and emergy analysis was based on the solar emergy units (solar emjoules). Emergy provided the methodology with a common basis for measuring the value of different kinds of energy, and for evaluating the contributions from nature and humanity. A comparison of emergy analysis with previous energy analysis was also performed.

  19. Structural analysis of DAEs

    Poulsen, Mikael Zebbelin

    2002-01-01

    analysis of DAE is original in the sense that it is based on a new matrix representation of the structural information of a general DAE system instead of a graph oriented representation. Also the presentation of the theory is found to be more complete compared to other presentations, since it e.g. proves....... The methodology is mainly based on strutural index analysis which is not limited by the index of the DAE as other methodologies. As a result of structural index analysis one can perform index reduction of the DAE and obtain the so-called augmented underlying ODE. It is also described, how to use the augmented......, by the implementation of the Simpy tool box. This is an object oriented system implemented in the Python language. It can be used for analysis of DAEs, ODEs and non-linear equation and uses e.g. symbolic representations of expressions and equations. The presentations of theory and algorithms for structural index...

  20. Principles of Fourier analysis

    Howell, Kenneth B

    2001-01-01

    Fourier analysis is one of the most useful and widely employed sets of tools for the engineer, the scientist, and the applied mathematician. As such, students and practitioners in these disciplines need a practical and mathematically solid introduction to its principles. They need straightforward verifications of its results and formulas, and they need clear indications of the limitations of those results and formulas.Principles of Fourier Analysis furnishes all this and more. It provides a comprehensive overview of the mathematical theory of Fourier analysis, including the development of Fourier series, "classical" Fourier transforms, generalized Fourier transforms and analysis, and the discrete theory. Much of the author''s development is strikingly different from typical presentations. His approach to defining the classical Fourier transform results in a much cleaner, more coherent theory that leads naturally to a starting point for the generalized theory. He also introduces a new generalized theory based ...

  1. Analysis in Banach spaces

    Hytönen, Tuomas; Veraar, Mark; Weis, Lutz

    2016-01-01

    The present volume develops the theory of integration in Banach spaces, martingales and UMD spaces, and culminates in a treatment of the Hilbert transform, Littlewood-Paley theory and the vector-valued Mihlin multiplier theorem. Over the past fifteen years, motivated by regularity problems in evolution equations, there has been tremendous progress in the analysis of Banach space-valued functions and processes. The contents of this extensive and powerful toolbox have been mostly scattered around in research papers and lecture notes. Collecting this diverse body of material into a unified and accessible presentation fills a gap in the existing literature. The principal audience that we have in mind consists of researchers who need and use Analysis in Banach Spaces as a tool for studying problems in partial differential equations, harmonic analysis, and stochastic analysis. Self-contained and offering complete proofs, this work is accessible to graduate students and researchers with a background in functional an...

  7. Multidimensional nonlinear descriptive analysis

    Nishisato, Shizuhiko

    2006-01-01

    Quantification of categorical, or non-numerical, data is a problem that scientists face across a wide range of disciplines. Exploring data analysis in various areas of research, such as the social sciences and biology, Multidimensional Nonlinear Descriptive Analysis presents methods for analyzing categorical data that are not necessarily sampled randomly from a normal population and often involve nonlinear relations. This reference not only provides an overview of multidimensional nonlinear descriptive analysis (MUNDA) of discrete data, it also offers new results in a variety of fields. The first part of the book covers conceptual and technical preliminaries needed to understand the data analysis in subsequent chapters. The next two parts contain applications of MUNDA to diverse data types, with each chapter devoted to one type of categorical data, a brief historical comment, and basic skills peculiar to the data types. The final part examines several problems and then concludes with suggestions for futu...

  11. Perspectives in shape analysis

    Bruckstein, Alfred; Maragos, Petros; Wuhrer, Stefanie

    2016-01-01

    This book presents recent advances in the field of shape analysis. Written by experts in the fields of continuous-scale shape analysis, discrete shape analysis and sparsity, and numerical computing who hail from different communities, it provides a unique view of the topic from a broad range of perspectives. Over the last decade, it has become increasingly affordable to digitize shape information at high resolution. Yet analyzing and processing this data remains challenging because of the large amount of data involved, and because modern applications such as human-computer interaction require real-time processing. Meeting these challenges requires interdisciplinary approaches that combine concepts from a variety of research areas, including numerical computing, differential geometry, deformable shape modeling, sparse data representation, and machine learning. On the algorithmic side, many shape analysis tasks are modeled using partial differential equations, which can be solved using tools from the field of n...

  12. Intelligent audio analysis

    Schuller, Björn W

    2013-01-01

    This book provides the reader with the knowledge necessary for comprehension of the field of Intelligent Audio Analysis. It firstly introduces standard methods and discusses the typical Intelligent Audio Analysis chain going from audio data to audio features to audio recognition.  Further, an introduction to audio source separation, and enhancement and robustness are given. After the introductory parts, the book shows several applications for the three types of audio: speech, music, and general sound. Each task is shortly introduced, followed by a description of the specific data and methods applied, experiments and results, and a conclusion for this specific task. The books provides benchmark results and standardized test-beds for a broader range of audio analysis tasks. The main focus thereby lies on the parallel advancement of realism in audio analysis, as too often today’s results are overly optimistic owing to idealized testing conditions, and it serves to stimulate synergies arising from transfer of ...

  13. Longitudinal categorical data analysis

    Sutradhar, Brajendra C

    2014-01-01

    This is the first book in longitudinal categorical data analysis with parametric correlation models developed based on dynamic relationships among repeated categorical responses. This book is a natural generalization of the longitudinal binary data analysis to the multinomial data setup with more than two categories. Thus, unlike the existing books on cross-sectional categorical data analysis using log linear models, this book uses multinomial probability models both in cross-sectional and longitudinal setups. A theoretical foundation is provided for the analysis of univariate multinomial responses, by developing models systematically for the cases with no covariates as well as categorical covariates, both in cross-sectional and longitudinal setups. In the longitudinal setup, both stationary and non-stationary covariates are considered. These models have also been extended to the bivariate multinomial setup along with suitable covariates. For the inferences, the book uses the generalized quasi-likelihood as w...

Summaries of the experience in establishing efficient and scalable operations to get prepared for CMS distributed analysis are presented, followed by the user experience in their current analysis activities.

  19. Materials analysis fast ions

    Denker, A; Rauschenberg, J; Röhrich, J; Strub, E

    2006-01-01

    Materials analysis with ion beams exploits the interaction of ions with the electrons and nuclei in the sample. Among the vast variety of possible analytical techniques available with ion beams we will restrain to ion beam analysis with ion beams in the energy range from one to several MeV per mass unit. It is possible to use either the back-scattered projectiles (RBS – Rutherford Back Scattering) or the recoiled atoms itself (ERDA – Elastic Recoil Detection Analysis) from the elastic scattering processes. These techniques allow the simultaneous and absolute determination of stoichiometry and depth profiles of the detected elements. The interaction of the ions with the electrons in the sample produces holes in the inner electronic shells of the sample atoms, which recombine and emit X-rays characteristic for the element in question. Particle Induced X-ray Emission (PIXE) has shown to be a fast technique for the analysis of elements with an atomic number above 11.

    AIM:To identify prognostic factors of patients with hepatocellular carcinoma (HCC), who were treated by orthotopic liver transplantation (OLT).METHODS: From January 2000 to October 2006,165 patients with HCC underwent OLT. Various clinicopathological risk factors for actuarial and recurrencefree survival were identified using the Kaplan-Meier method with the log-rank test. The Cox proportional hazards model was used to identify independently predictive factors for actuarial and recurrence-free survival, which were used to propose new selection criteria. We compared the outcome of the subgroup patients meeting different criteria. Survival analysis was performed using the Kaplan-Meier method with the log-rank test.RESULTS: The median follow-up was 13.0 mo (2.8-69.5 mo). Overall, 1-, 2-, 3- and 5-year actuarial survival was 73.3%, 45.6%, 35.4% and 32.1%, respectively.One-, 2-, 3- and 5-year overall recurrencefree survival was 67.0%, 44.3%, 34.5% and 34.5%,respectively. In univariate analysis, number of tumors,total tumor size, lobar distribution, differentiation, macrovascular invasion, microvascular invasion, capsulation of the tumor, and lymph node metastasis were found to be associated significantly with actuarial and tumor-free survival. By means of using the multivariate Cox proportional hazards model, total tumor size and macrovascular invasion were found to be independent predictors of actuarial and tumor-free survival. When the selection criteria were expanded into the proposed criteria, there was no significant difference in 1-, 2-, 3- and 5-year actuarial and tumor-free survival of the 49 patients who met the proposed criteria (97.6%, 82.8%, 82.8% and 82.8%, and 90.7%, 82.8%, 68.8% and 68.8%, respectively)compared with that of patients who met the Milan or University of California, San Francisco (UCSF) criteria.CONCLUSION: Macrovascular invasion and total tumor diameter are the strongest prognostic factors.The proposed criteria do not adversely affect the

    1995-09-01

    The DOE Hydrogen Program is supporting research, development, and demonstration activities to overcome the barriers to the integration of hydrogen into the Nation`s energy infrastructure. Much work is required to gain acceptance of hydrogen energy system concepts and to develop them for implementation. A systems analysis database has been created that includes a formal documentation of technology characterization profiles and cost and performance information. Through a systematic and quantitative approach, system developers can understand and address important issues and thereby assure effective and timely commercial implementation. This project builds upon and expands the previously developed and tested pathway model and provides the basis for a consistent and objective analysis of all hydrogen energy concepts considered by the DOE Hydrogen Program Manager. This project can greatly accelerate the development of a system by minimizing the risk of costly design evolutions, and by stimulating discussions, feedback, and coordination of key players and allows them to assess the analysis, evaluate the trade-offs, and to address any emerging problem areas. Specific analytical studies will result in the validation of the competitive feasibility of the proposed system and identify system development needs. Systems that are investigated include hydrogen bromine electrolysis, municipal solid waste gasification, electro-farming (biomass gasifier and PEM fuel cell), wind/hydrogen hybrid system for remote sites, home electrolysis and alternate infrastructure options, renewable-based electrolysis to fuel PEM fuel cell vehicle fleet, and geothermal energy used to produce hydrogen. These systems are compared to conventional and benchmark technologies. Interim results and findings are presented. Independent analyses emphasize quality, integrity, objectivity, a long-term perspective, corporate memory, and the merging of technical, economic, operational, and programmatic expertise.

    The purpose of this work is to analyze patterns of care and outcome after stereotactic body radiotherapy (SBRT) for centrally located, early-stage, non-small cell lung cancer (NSCLC) and to address the question of potential risk for increased toxicity in this entity. A total of 90 patients with centrally located NSCLC were identified among 613 cases in a database of 13 German and Austrian academic radiotherapy centers. The outcome of centrally located NSCLC was compared to that of cases with peripheral tumor location from the same database. Patients with central tumors most commonly presented with UICC stage IB (50 %), while the majority of peripheral lesions were stage IA (56 %). Average tumor diameters were 3.3 cm (central) and 2.8 cm (peripheral). Staging PET/CT was available for 73 and 74 % of peripheral and central tumors, respectively. Biopsy was performed in 84 % (peripheral) and 88 % (central) of cases. Doses varied significantly between central and peripheral lesions with a median BED{sub 10} of 72 Gy and 84 Gy, respectively (p < 0.001). Fractionation differed as well with medians of 5 (central) and 3 (peripheral) fractions (p < 0.001). In the Kaplan-Meier analysis, 3-year actuarial overall survival was 29 % (central) and 51 % (peripheral; p = 0.004) and freedom from local progression was 52 % (central) and 84 % (peripheral; p < 0.001). Toxicity after treatment of central tumors was low with no grade III/IV and one grade V event. Mortality rates were 0 and 1 % after 30 and 60 days, respectively. Local tumor control in patients treated with SBRT for centrally located, early-stage NSCLC was favorable, provided ablative radiation doses were prescribed. This was, however, not the case in the majority of patients, possibly due to concerns about treatment-related toxicity. Reported toxicity was low, but prospective trials are needed to resolve the existing uncertainties and to establish safe high-dose regimens for this cohort of patients. (orig.) [German] Ziel

    The Design-through-Analysis Realization Team (DART) is chartered with reducing the time Sandia analysts require to complete the engineering analysis process. The DART system analysis team studied the engineering analysis processes employed by analysts in Centers 9100 and 8700 at Sandia to identify opportunities for reducing overall design-through-analysis process time. The team created and implemented a rigorous analysis methodology based on a generic process flow model parameterized by information obtained from analysts. They also collected data from analysis department managers to quantify the problem type and complexity distribution throughout Sandia's analyst community. They then used this information to develop a community model, which enables a simple characterization of processes that span the analyst community. The results indicate that equal opportunity for reducing analysis process time is available both by reducing the ''once-through'' time required to complete a process step and by reducing the probability of backward iteration. In addition, reducing the rework fraction (i.e., improving the engineering efficiency of subsequent iterations) offers approximately 40% to 80% of the benefit of reducing the ''once-through'' time or iteration probability, depending upon the process step being considered. Further, the results indicate that geometry manipulation and meshing is the largest portion of an analyst's effort, especially for structural problems, and offers significant opportunity for overall time reduction. Iteration loops initiated late in the process are more costly than others because they increase ''inner loop'' iterations. Identifying and correcting problems as early as possible in the process offers significant opportunity for time savings.

    2010-01-01

    NASA/NESSUS 6.2c is a general-purpose, probabilistic analysis program that computes probability of failure and probabilistic sensitivity measures of engineered systems. Because NASA/NESSUS uses highly computationally efficient and accurate analysis techniques, probabilistic solutions can be obtained even for extremely large and complex models. Once the probabilistic response is quantified, the results can be used to support risk-informed decisions regarding reliability for safety-critical and one-of-a-kind systems, as well as for maintaining a level of quality while reducing manufacturing costs for larger-quantity products. NASA/NESSUS has been successfully applied to a diverse range of problems in aerospace, gas turbine engines, biomechanics, pipelines, defense, weaponry, and infrastructure. This program combines state-of-the-art probabilistic algorithms with general-purpose structural analysis and lifting methods to compute the probabilistic response and reliability of engineered structures. Uncertainties in load, material properties, geometry, boundary conditions, and initial conditions can be simulated. The structural analysis methods include non-linear finite-element methods, heat-transfer analysis, polymer/ceramic matrix composite analysis, monolithic (conventional metallic) materials life-prediction methodologies, boundary element methods, and user-written subroutines. Several probabilistic algorithms are available such as the advanced mean value method and the adaptive importance sampling method. NASA/NESSUS 6.2c is structured in a modular format with 15 elements.

    2015-01-01

    The ATLAS experiment accumulated more than 140 PB of data during the first run of the Large Hadron Collider (LHC) at CERN. The analysis of such an amount of data for the distributed physics community is a challenging task. The Distributed Analysis (DA) system of the ATLAS experiment is an established and stable component of the ATLAS distributed computing operations. About half a million user jobs are daily running on DA resources, submitted by more than 1500 ATLAS physicists. The reliability of the DA system during the first run of the LHC and the following shutdown period has been high thanks to the continuous automatic validation of the distributed analysis sites and the user support provided by a dedicated team of expert shifters. During the LHC shutdown, the ATLAS computing model has undergone several changes to improve the analysis workflows, including the re-design of the production system, a new analysis data format and event model, and the development of common reduction and analysis frameworks. We r...

  16. A PROOF Analysis Framework

    The analysis of the complex LHC data usually follows a standard path that aims at minimizing not only the amount of data but also the number of observables used. After a number of steps of slimming and skimming the data, the remaining few terabytes of ROOT files hold a selection of the events and a flat structure for the variables needed that can be more easily inspected and traversed in the final stages of the analysis. PROOF arises at this point as an efficient mechanism to distribute the analysis load by taking advantage of all the cores in modern CPUs through PROOF Lite, or by using PROOF Cluster or PROOF on Demand tools to build dynamic PROOF cluster on computing facilities with spare CPUs. However using PROOF at the level required for a serious analysis introduces some difficulties that may scare new adopters. We have developed the PROOF Analysis Framework (PAF) to facilitate the development of new analysis by uniformly exposing the PROOF related configurations across technologies and by taking care of ...

    The experience of 28 allotransplantations of ABO-incompatible kidneys was compared with the treatment results of 38 ABO-compatible renal transplantations. The transplanted kidney function, morphological changes of the transplanted kidney and the comparative analysis of actuary survival in both groups showed no significant difference. The results of the study prove the validity of the kidney transplantation from the ABO-incompatible donors.

  20. Multivariate Skew-Normal Individual Excess-of-Loss Reserving

    Pigeon, Mathieu; Denuit, Michel

    In excess-of-loss reinsurance, only claims with incurred loss above a reporting threshold speci_ed in the treaty are noti_ed to the reinsurer. The data available for reinsurance pricing and reserving are, thus, incomplete and failing to account for this limitation may bias the actuarial analysis. The collective approach based on aggregate development triangles cannot deal with this kind of incompleteness. This is why we develop here an individual reserving method combining paid and incurred l...
