There is an ambiguity in Amartya Sen’s capability approach as to what constitutes an individual’s resources, conversion factors
and valuable functionings. What we here call the “circularity problem” points to the fact that all three concepts seem to
be mutually endogenous and interdependent. To econometrically account for this entanglement we suggest a panel vector autoregression
approach. We analyze the intertemporal interplay of the above factors over a time horizon of 15 years using the BHPS data
set for Great Britain, measuring individual well-being in functionings space with a set of basic functionings, comprising
“being happy”, “being healthy”, “being nourished”, “moving about freely”, “being well-sheltered” and “having satisfying social
relations”. We find that there are indeed functionings that are resources for many other functionings (viz. “being happy”)
while other functionings (“being well-sheltered” and “having satisfying social relations”) are by and large independent, thus
shedding light on a facet of the capability approach that has been neglected so far. 相似文献

There has been considerable interest in studying the magnitude and type of inheritance of specific diseases. This is typically derived from family or twin studies, where the basic idea is to compare the correlation for different pairs that share different amount of genes. We here consider data from the Danish twin registry and discuss how to define heritability for cancer occurrence. The key point is that this should be done taking censoring as well as competing risks due to e.g. death into account. We describe the dependence between twins on the probability scale and show that various models can be used to achieve sensible estimates of the dependence within monozygotic and dizygotic twin pairs that may vary over time. These dependence measures can subsequently be decomposed into a genetic and environmental component using random effects models. We here present several novel models that in essence describe the association in terms of the concordance probability, i.e., the probability that both twins experience the event, in the competing risks setting. We also discuss how to deal with the left truncation present in the Nordic twin registries, due to sampling only of twin pairs where both twins are alive at the initiation of the registries. 相似文献

Learning theory predicts that, given the repeated choice to bet between two concurrently available slot machines, gamblers will learn to bet more money on the machine with higher expected return (payback percentage) or higher win probability per spin (volatility). The purpose of this study was to investigate whether this occurs when the two machines vary orthogonally on payback percentage and volatility. The sample comprised 52 first year psychology students (mean age = 20.3 years, 20 females, 32 males) who had played a gaming machine at least once in the previous 12 months. Participants were administered a battery of questionnaires designed to assess level of knowledge on the characteristics and operation of poker machines, frequency of poker machine play in the past 12 months, personality traits of impulsivity and capacity for cognitive reflection, and gambling beliefs. For the experimental task, participants were instructed to play on two PC-simulated electronic gaming machines (EGMs or slot machines) that differed on payback percentage and volatility, with the option of freely switching between EGMs after a practice phase. Results indicated that participants were able to easily discriminate between machines and manifested a preference to play machines offering higher payback or volatility. These findings diverged from previous findings of no preference for play on higher payback/volatility machines, potentially due to of the current study’s absence of the option to make multi-line and multi-credit bets. It was concluded that return rate parameters like payback percentage and volatility strongly influenced slot machine preference in the absence of betting options like multi-line bets, though more research is needed to determine the effects of such betting options on player distribution of money between multiple EGMs. 相似文献

This study examines new immigrants from the former USSR, their attitudes, expectations and the awareness of change in themselves and in their fellow immigrants. Participants demonstrated attitudes toward the new society which differed dramatically depending on the sphere of life being examined: cultural, institutional, or quotidian. Participants displayed a tendency toward integration in the institutional and quotidian spheres, but not in the cultural. An attitude toward integration did not automatically lead to an awareness of change in the new immigrants themselves. Participants consistently reported higher degrees of change in fellow immigrants in comparison to themselves. The issue of preservation of self‐identity through socio‐cultural conservation is discussed, as well as the relevance of these findings for Vygotsky's cultural‐historical theory and Feuerstein's theory of mediated learning. 相似文献

One of the criteria used by judges of the Family Court in reaching custody decisions is the wishes of the child. A total of 104 children who were subjects of custody disputes were interviewed for the purpose of trying to ascertain their custodial wishes. Most children expressed a wish, and this preference was usually to remain with the parent the child was already living with. Children's wishes as to whether to remain where they were living or to move to live with the other parent, and their preferences as to whether to live with the mother or the father, did not differ according to age or sex. 相似文献
