Data-driven versions of Sobolev tests of uniformity on compact Riemannian manifolds are reviewed and their large-sample asymptotic properties are given. A variant which is suitable for product manifolds is introduced. Data-driven goodness-of-fit tests of multivariate distributions are derived from data-driven tests of uniformity on tori. 相似文献

This paper presents an analysis of levels of life expectancy and their patterns of change among six socio-economically differentiated sub-populations of England and Wales for the period 1851–1911. Differences in mortality levels among these sub-groups and their rates of change are analyzed with respect to three groups of explanatory variables, viz., environmental, stratification and demographic variables. Their relative importance for different periods is assessed and discussed. The findings show consistency with two previous studies, which have suggested that medical advances had little effect on the increase in life expectancy during the second half of the nineteenth century. The present paper supports the results of one study in that public health measures affected life expectancies earlier, while subsequently, the increase in standards of living was more important. 相似文献

There are production situations where a production facility (e.g. a machine) is used intermittently to produce lot sizes of certain products. Upon completion of production run, the facility may not be available for a random amount of time due to several reasons, such as: the facility needs to be maintained and the maintenance time is random due to unforeseen circumstances; or that the facility is leased by different manufacturers and the demand for the facility is random. As a result of machine unavailability, stock-out situations might arise. This paper extends the work of Abboud et al . (2000, Computers and Operations Research , 27 , 335-351) by assuming learning and forgetting in production. A new mathematical model is developed with numerical examples and sensitivity analysis provided. Furthermore, this paper determines how the overall inventory cost is influenced by the nature of the random variable that represents the unavailability time of the production facility. 相似文献

In this paper we analyze the explicit representation of fixed agenda social choice correspondences under different rationality
assumptions (independence, Pareto optimality, etc.). It is well known that, under some of these assumptions, the existence
of dictators, oligarchies or individuals with veto power can be proven ([6] and [10]); but only a partial characterization
of the social choice set is obtained. We establish a relationship between the social choice set and the individuals' maximal
sets, which explicitly describes a fixed agenda social choice correspondence that satisfies these rationality assumptions.

This paper investigates the measurement of trust transfer in interpersonal contexts. Despite the importance of this topic, little evidence of comparable indicators exists to fill the current gap in knowledge regarding the measurement of interpersonal transference of trust and its reciprocal. We propose a modification of the classical structure of a widely accepted experimental setting for analyzing trust (i.e. a trust game) and build two indexes for the measurement of trust transfer and its reciprocation. Several properties of these indicators are investigated to examine their robustness and accuracy for measuring the transference of interpersonal trust. Furthermore, using data from our own modified trust game, we provide an empirical examination of both indexes. The results show that the existence of a mutually known third party fosters a stronger willingness to achieve cooperative behavior in an anonymous trust game; thus, the transference of interpersonal trust works in both directions of the dyad. 相似文献

A societal decision to protect over 9 million acres of land and water for its wilderness character in the early 1960s reflected US wealth in natural resources, pride in the nation’s cultural history and our commitment to the well-being of future generations to both experience wild nature and enjoy benefits flowing from these natural ecosystems. There is no question that our relationship with wilderness has changed. Individually it is probably quite easy to examine differences in the role wilderness plays in the quality of our lives today compared to some previous time. But how the role of wilderness protection has changed for society is more difficult to describe. In only a few places do we have data across multiple decades that would allow us to even examine how users or their use may have changed over time. At the Boundary Waters Canoe Area Wilderness in northern Minnesota we are fortunate to have multiple studies that can give us some 40 years of insight into how some aspects of use have changed there. For example, an analysis of results of visitor studies at the Boundary Waters Canoe Area Wilderness in 1969, 1991 and 2007 reveal some big differences in who is out there today, most notably the presence of a much older, more experienced and better educated user population, almost exclusively white and predominantly male. It is time to decide whether the best thing for wilderness and or society is to try to restore historic patterns of use (to include younger people, the less wealthy and lower educated) in greater numbers, to try to identify new markets within growing underrepresented populations, or adapt our perception of wilderness stewardship to better include planning for emerging social values of a new generation with other indicators of well-being. A growing population with greater dependence on ecosystem services provided by protected nature could lead to wilderness protection becoming an important quantitative and qualitative element of quality of life indices in the very near future. 相似文献

This essay combines Burke's burlesque frame and Jamieson's double binds to create a hybrid gendered theory for rhetorically analyzing the aggressive sexualization of 2008 United States vice presidential candidate Sarah Palin. The essay develops our theory titled the “burlesque binds” and explicates a specific form of a burlesque bind: the “MILF frame.” Palin's aggressively sexualized representation was united under the crass acronym MILF, which stands for “Mom I'd Like to Fuck.” The MILF frame emphasized Palin's feminine qualities, positioning her as a “trophy vice” with no political acumen, and highlighted her masculine behaviors, but deflated them through sexual objectification. The unification of the binds and burlesque theories reveals how Palin's role as a social actor was not simply circumscribed but shut down: she was deemed unfit by both masculine and feminine standards, by both public and private sphere conventions. Although Sarah Palin has arguably been the most prevalent subject of the political MILF frame, our essay catalogues other instances of female political leaders experiencing this type of symbolic degradation, suggesting the MILF frame's vast influence. 相似文献

This paper identifies interrelationships between evidence-based practice (EBP), radical structuralism, and culture, arguing that culturally-specific beliefs and norms should be integrated into evidence-based, cross-cultural partnerships within child and family service systems. A single case study of family advocate training in evidence-based practice is provided as an illustration of, and impetus for, the development of a format for use with community-based and ethnically-diverse parent/family advocates. The lessons learned from teaching evidence-based practice to a parent advocate in a particular child welfare service system are highlighted. The use of enhanced roles for social workers and indigenous social capital and resources, such as family advocates as allies, is recommended to help achieve a greater degree of accountability, cooperation, and core understanding in the use of EBP. By training racially-diverse foster parents as mental health advocates to work collaboratively with policymakers, community groups, and family participants, proponents of EBP will reach and benefit more diverse populations. 相似文献
