This paper explores the degree of interdisciplinarity of evolutionary approaches to the study of human behavior, and the implications that any such interdisciplinarity may have for the future of evolutionary psychology (EP) as a field of scholarship. To gauge the extent of interdisciplinarity of EP, the departmental affiliation of first-authors from 1000 journal articles evenly distributed across ten leading peer-reviewed psychology journals was assessed. Findings show that journals that are evolutionary-based have more first-authors from outside of psychology, and also include a wider variety of represented disciplines. These findings are discussed in terms of their influence on the future of EP, as a model for interdisciplinary research. EP's future will be successful if it continues to promote interdisciplinarity as well as recognize the epistemological worth of multiple evolutionary paradigms and frameworks. Evolutionary principles have been successfully applied to a broad range of topics, suggesting there is great utility in evolution serving as a common language for interdisciplinary pursuits within the behavioral and social sciences. As such, academic programs such as Evolutionary Studies (EvoS) programs, whose presence continues to increase across academic institutions worldwide, epitomize the future of successful interdisciplinary scholarly training. 相似文献

Uncertain time of retirement and uncertain structure of retirement benefits are risk factors for life insurance companies. Nevertheless, classical life insurance models assume these are deterministic. In this paper, we include the risk from stochastic time of retirement and stochastic benefit structure in a classical finite-state Markov model for a life insurance contract. We include discontinuities in the distribution of the retirement time. First, we derive formulas for appropriate scaling of the benefits according to the time of retirement and discuss the link between the scaling and the guarantees provided. Stochastic retirement creates a need to rethink the construction of disability products for high ages and ways to handle this are discussed. We show how to calculate market reserves and how to use modified transition probabilities to calculate expected cash flows without significantly more complexity than in the traditional model. At last, we demonstrate the impact of stochastic retirement on market reserves and expected cash flow in numerical examples. 相似文献

In the two-person ultimatum game, an allocator is required to split a given sum of money with a recipient. Subsequently the
recipient can either accept or reject the offer. If it is accepted, both players receive their respective splits, while if
it is rejected neither of them get anything. Using evolutionary psychology as the theoretical framework, we predicted and
found that males made more generous offers when pitted against a female as opposed to a male. While females made equal offers
independently of the sex of the recipient. That male allocators are altruistic towards female recipients and competitive with
male recipients is construed as a manifestation of social rules, which evolve from the male pre-disposition to use resources
for attracting mates. In contrast, females have not evolved such a pre-disposition, and thus, female allocators are more concerned
about fairness when making offers to recipients. Several alternate explanations of the above findings are discussed and the
evolutionary explanation is concluded as the most parsimonious one. Other potential moderators that are amenable to evolutionary
explanations, namely, physical attractiveness, age and ethnicity of participants, are also discussed in this context.

Past investigations of the income gaps between Jews and non-Jews in Israel treat non-Jews as one group. In this paper we separate the non-Jewish group into three main religious minorities: Muslims, Christians, and Druze and focus on the northern part of Israel, where most minorities live. Using the latest Israeli census, we find significant explained and unexplained income gaps in favor of Jews. The unexplained gaps tend to be larger the more educated the individual. Jews have much higher representation in the more lucrative occupations, and earn significantly more in them. Muslims generally suffer from the largest income gaps, while Druze have the lowest income gaps, reflecting direct and indirect benefits reaped from serving in the army. Among minorities, Christians are the most educated and most concentrated in the top occupations, which explains why they have the lowest gaps in the highest percentiles of the income distribution. 相似文献

One of the most ubiquitous creative copy decisions in advertising is to use young attractive women in decorative roles. Contrary to the mantra chanted by some staunch feminists, advertisers are not involved in a patriarchal white‐male‐dominated conspiracy to derogate, exploit, subjugate, and dominate women. Advertisers are concerned with providing messages that are maximally effective to their relevant target audience. Accordingly, they are well aware that in certain situations the use of decorative female models will appeal to a particular group of their constituency. Using evolutionary psychology as the explicative framework, it is argued that the greater use of young and attractive women in decorative roles in advertising is steeped in the differential mating strategies of the two sexes. An analysis of several content‐analytic studies demonstrates that the more frequent use of women as young and attractive decorative models is longitudinally stable and culturally invariant further attesting to the Darwinian roots of this phenomenon. © 2004 Wiley Periodicals, Inc. 相似文献

AbstractBenefit segmentation is a long-standing marketing approach that emphasises the ‘what’ and ‘how’ dimensions of consumer benefits; that is, what benefits consumers perceive in product/service consumption, and how such benefits are perceived. This research proposes a fresh time-based approach to benefit segmentation – namely, focusing on the ‘when’ element or when in time benefits take effect. Drawing upon a survey of UK consumers, it explains and discusses consumption motivations through examining antecedents of temporally dominated benefits in application to organic food. Specifically, the study investigates why some consumers predominantly seek present-based benefits vis-à-vis future-based benefits or vice versa in organic food purchase and consumption behaviour. Using correlation and regression analyses, the research findings establish significant associations of level of involvement, prior knowledge level, and product usage level, and some association of time orientation with the temporally emphasised consumption benefits consumers ultimately pursue. Overall, the research highlights the added contribution of a time perspective in a benefit segmentation approach which can assist marketers in understanding better and communicating more effectively with consumers through drawing up consumer profiles based on when in time their dominantly pursued benefit for an offering is perceived to take effect. 相似文献

One of the main trends in the labor market in recent years is the aging of the workforce, which partly results from older workers delaying retirement. Using the Current Population Survey from the Bureau of Labor Statistics, we find that the trend of delaying retirement began as early as the mid-1990s, accelerated since the beginning of the latest recession, and has continued into the first four months of 2011. We also find that the development of this trend varied significantly across socioeconomic groups, industries, and occupations. We then use The Conference Board Consumer Confidence Survey to measure the impact of home prices and labor market conditions on retirement decisions, and find that workers in households that experienced labor loss/compensation cuts and significant declines in home prices were more likely to plan to delay retirement. These results also indicate that workers from states that suffered from large declines in home prices and high unemployment are more likely to delay retirement. We conclude by discussing potential economic and business implications. 相似文献
