These experiments are concerned with individual behavior under risk and under uncertainty. By exploiting the isolation effect the experiments were able to offer to 134 subjects the possibility of actually gaining or losing an important sum of money.The experimental data show that under risk as well as under complete ignorance the subjects' attitudes towards prospects of gains and towards prospects of losses are totally unrelated.The data also show that when facing prospects of gains, the subjects generally take the exact probabilities of the events into account, whereas, when facing prospects of losses many of then have only recourse to coarser categories of plausibility, or even no longer use their information at all. 相似文献

Starting from perspectives on functioning and wellbeing, the aim of the present study was to investigate positive and negative affect, self-perceived life satisfaction and happiness in a group of 74 Palestinian children exposed to political violence. We hypothesized that the children in our sample would display generally satisfactory wellbeing and good functioning in terms of positive affect, life satisfaction and happiness, despite their negative life conditions. Both quantitative and qualitative analysis of the dimensions of participants' wellbeing was carried out. In particular, we explored the ecological dimensions affecting the wellbeing of Palestinian children through content analysis of narratives produced by the group of participants. Positive emotions were found to contribute to wellbeing and life satisfaction in children, acting as protective factors in dealing with daily violence. The children displayed a range of personal resources facilitated above all by the functioning community structure supporting them. Implications for clinical intervention are discussed. 相似文献

The skew normal distribution family is an attractive distribution family due to its mathematical tractability and inclusion of the normal distribution as the special case. It has wide applications in many applied fields such as finance, economics, and medical research. Such a distribution family has been studied extensively since it was introduced by Azzalini in 1985 for the first time. Yet, few work has been done on the study of change point problem related to this distribution family. In this article, we propose the likelihood ratio test (LRT) to detect changes in the parameters of the skew normal distribution associated with some asymptotic results of the test statistic. Simulations have been conducted under different scenarios to investigate the performance of the proposed method. Comparisons to some other existing method indicate the comparable power of the method in detecting changes in parameters of the skew normal distribution model. Applications on two real data: Brazilian and Tanzanian stock returns illustrate the detection procedure. 相似文献

Moving Extremes Ranked Set Sampling (MERSS) is a useful modification of Ranked Set Sampling (RSS). Unlike RSS, MERSS allows
for an increase of set size without introducing too much ranking error. The method is considered parametrically under exponential
distribution. Maximum likelihood estimator (MLE), and a modified MLE are considered and their properties are studied. The
method is studied under both perfect and imperfect ranking (with error in ranking). It appears that these estimators can be
real competitors to the MLE using the usual simple random sampling (SRS). 相似文献

This paper reviews the strategic decision‐making process literature with respect to the synoptic formalism/political incrementalism debate. Procedural rationality is chosen as a representative of the synoptic formalism perspective; and both intuitive synthesis and political behaviour are employed as representatives of the political‐incrementalism perspective. In this paper, the author discusses the theoretical underpinnings of these three process dimensions, as well as the key research efforts gathered together under each perspective. In conducting this review, a number of areas have been identified which could profitably be examined further, and a number of implications for managers will be highlighted and discussed. 相似文献

The problem of testing the hypothesis of equality of covariance matrices in the presence of two-stage sampling is considered. Asymptotic test procedures based on linearization, grouping and jackknifing with or without transformation are proposed. The finite sample properties of these procedures are investigated in sampling experiments both from simulated known distributions and from a natural population. 相似文献

Most of the available literature on accelerated life testing deals with tests that use only one accelerating variable and no other explanatory variables. Frequently, however, there is a need to use more than one accelerating or other experimental variables. Examples include a test of capacitors at higher than usual levels of temperature and voltage, and a test of circuit boards at higher than usual levels of temperature, humidity, and voltage. M-step, step-stress models are extended to include k stress variables. Optimum M-step, step-stress designs with k stress variables are found. The polynomial model is considered as a special case, and a lack of fit test is discussed. Also a goodness-of-fit test is proposed and the appropriateness of using its asymptotic chi-square distribution for small samples is shown. 相似文献

This review presents the physical performance outcomes of randomised trials investigating exercise programmes that included
balance exercise for older people with dementia. A systematic literature search through five computerised bibliographic databases
until February 2009 was carried out. Of 1,038 potentially relevant published articles, only seven met the inclusion criteria
and were extracted. Findings from the review for a total of 632 participants showed that almost all of the included studies
addressed exercise or physical activities as the main intervention; however, only two of the studies focused on balance exercise.
The effect size values varied from no effect (0.00) to a large effect (3.29) of the interventions for a range of physical
performance outcome measures. Findings also suggest that it is feasible to conduct exercise programmes with older people with
dementia. However, further studies with more specific exercise designed to improve balance performance in order to prevent
falls are required for older people with dementia. 相似文献

ABSTRACTThe explanatory study aimed to examine the role of Facebook use (intensity of Facebook use, Facebook relationship maintenance behaviors, duration of use, and number of ties), motives of using Facebook (making new social ties, maintaining existing social ties, seeking and sharing information, self-expression, self-documentation, and recreation), and sociodemographic characteristics (age, education, gender, and monthly family income) in predicting the formation of bridging and bonding social capital among youth. Opting Putnam’s theory of social capital, a survey was conducted from eight randomly selected universities of Lahore, Pakistan. A total of 1,245 students, had an average age of 21, were participated in this study. Stepwise multiple linear regression technique was used to explain bridging and bonding social capital. The study found that motives of using Facebook had a major role in predicting bridging and bonding social capital of the students. The intensity of Facebook use and Facebook relationship maintenance behaviors were also positively correlated with bridging and bonding social capital. Except for the age for bonding social capital, no other sociodemographic variables had an influence on bridging and bonding social capital. 相似文献

Interviews were held with 12 Muslim Palestinian women from Israel, presently studying in Jordan (6) or who had completed their higher education in Jordan (6). They explained the factors that pushed or pulled them to study in Jordan, the independence that they experienced there, the empowerment they achieved, and the price they paid when they returned to Arab society in Israel. The Arab cultural space in Jordan is defined as both foreign and close, due to its geographical and cultural proximity, and yet its distance from home and patriarchal supervision. The research findings indicate that this situation influences the formation of these women's gender identity and their empowerment but also creates much pain and conflict. The Palestinian women's new identity, formed during their studies, assists them in their efforts to reintegrate and establish their status when they return from their academic studies abroad to their society of origin, Muslim Arab society in Israel. 相似文献
