We suppose that L x i = Fq(μi, KiK) for i=1,...,p, where the independent Fisher distributions on the unit sphere in Rq have modal vectors μi and known concentrations KiK, where K will be large—in fact, to obtain asymptotic distributions, we will let K tend to infinity. The term x'iXj=cos 0ij estimates cos 0ij= μiμy. The asymptotic joint distribution of the terms will be studied when all the vectors μi μ are distinct, and for the special case when all the vectors μi=μ, so that all the terms are zero. These very different results have a variety of applications as well as being interesting in themselves. One of these applications is the 'multiple comparisons problem' for unit vectors. However, it was found necessary to give here a different way of solving this problem. 相似文献

Just recently, information systems with rather unique characteristics have begun to emerge. These systems usually referred to as Decision Support Systems, feature decision models, a data base and the decision maker as subsystems and are specifically oriented to supporting decision making. This article examines Decision Support Systems and their application to banks. 相似文献

The study concerns itself with a comparison of the value system of bikers, those who pursue a life‐style centered around motorcycles, with that of a religious sect Several parallels are drawn with the religious sect, in the function of the life‐style of bikers as well as the degree of commitment. The study is the product of several years of participant observation by the author. 相似文献

The decision to remain in or leave the parental home represents the first housing career choice of young people. In this paper,
we examine the parental home leaving outcomes for Australian birth cohorts in the twentieth century using recall questions
contained in the Household, Income and Labour Dynamics in Australia Survey. The findings from survival analysis and hazard
function modelling is that a continuous, gradual reduction in the age of first leaving the parental home in Australia is evident
up to the 1947–51 birth cohort, followed by stability and then a rise in age of first leaving home for the most recent birth
cohorts. Birth cohort effects remain significant even after other measured determinants of parental home leaving are taken
into account. The paper confirms the strong roles that education, family background and ethnicity have on parental home leaving
outcomes. 相似文献

A longitudinal study of domestic water conservation behavior 总被引:1,自引:0,他引:1
A 1988 study of a school-linked sample in a metropolitan and a regional urban area established baseline data for knowledge, attitudes, intentions, and behavior with regard to water management and conservation (Murphy, Watson, & Moore, 1991). This paper reports on a 1991 follow-up, utilising both longitudinal and cross-sectional samples of students, teachers and parents, which aimed at identifying changes within the community since the initial study. In addition, the study sought to identify factors influential in change and the extent to which the pattern of relationships between knowledge, attitudes, intentions and behaviors had remained stable over time. The results indicated that there was a move towards greater conservation as measured by the variables studied over the three year period, that media interventions and water costs were perceived as influential in this change, and that reported conserving behavior continued to be better predicted by stated intentions than by knowledge. Little difference in the pattern of intervariable relationships was observed across the time span studied. 相似文献

In this article, we study behavior in a series of two‐player supply chain game experiments. Each player simultaneously chooses a capacity before demand is realized, and sales are given by the minimum of realized demand and chosen capacities. We focus on the differences in behavior under fixed pairs and random rematching. Intuition suggests that long‐run relations should lead to more profitable outcomes. However, our results go against this intuition. While subjects' capacity choices are better aligned (i.e., closer together) under fixed pairs, average profits are more variable. Moreover, learning is slower under fixed pairs—so much so that over the last five periods, average profits are actually higher under random rematching. The underlying cause for this finding appears to be a “first‐impressions” bias, present only under fixed matching, in which the greater the misalignment in initial choices, the lower are average profits. 相似文献

Ninety-four (62%) survey responses in the Japanese language from 151 corporate public relations professionals in Japan were analyzed to investigate how Japanese management styles have changed since the recent economic recession, and how present management styles have impacted public relations practice in Japan. Findings suggest today’s Japanese management styles are not a static system unaffected by the economic pressures, and that current public relations practices in Japan align more closely with mixed models of public relations practiced in Western societies. 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 study investigated differences in depressive symptoms, loneliness, and self-esteem for monosexual (lesbian, gay) and plurisexual (bisexual, pansexual, queer) sexual minority youth (SMY) by relationship status (single, partnered) and relationship configuration (same-gender partner, different-gender partner). Participants included 338 SMY (Mage = 19.10 years) who reported on their relationship status, partner's gender identity, well-being, and ability to confide in partner about LGBTQ issues. Results indicated that for plurisexual youth, single status was associated with greater loneliness; plurisexual youth with same-gender partners reported fewer depressive symptoms and marginally greater ability to confide in their partner about LGBTQ issues than those with different-gender partners. Findings reveal similarities across SMY while also highlighting some unique challenges among plurisexual youth with different-gender partners. 相似文献
