Complete ranking procedures with quadratic loss

Suppose that one wishes to rank k normal populations, each with common variance σ² and unknown means θ_i (i=1,2,…,k). Independent samples of size n are taken from each population, and the sample averages are used to rank the populations. In this paper, we investigate what sample sizes, n, are necessary to attain “good” rankings under various loss functions. Section discusses various loss functions and their interpretation. Section 2 gives the solution for a reasonable non-parametric loss function. Section 3 gives the solution for a reasonable parameteric loss function.     

Resolving Identity Conflict: Gay,Lesbian, and Queer Individuals with a Christian Upbringing

Gay, lesbian, and queer individuals with a Christian upbringing often experience conflict between religion and sexual identity. The purpose of this grounded theory study was to understand how gay, lesbian, and queer-identified individuals with a Christian upbringing resolve conflict between sexual identity and religious beliefs. Analysis of in-depth interviews with 15 participants led to 3 conclusions. First, resolving the discord between sexual identity and religious beliefs is a five-stage process of internal conflict resolution. Second, personal and contextual factors affect every aspect of the resolution process. Finally, faith development and sexual identity development are intertwined and fluid constructions.     

An intelligent dynamic simulation model for designing software development processes

This paper describes a computer-aided software development process design. This is a computerized intelligent tool designed to aid managers of software development projects in planning, managing and controlling the development process of medium to large scale software projects. The application of this computerized tool should help reduce the uncertainties involved in the budget, personnel and schedule planning of software development projects.     

A Case Study of Mortgage Refinancing Discrimination: African American Intergenerational Wealth*

A case study approach is taken to examine differences between African Americans and white Americans in their respective approval/denial rates for home mortgage refinancing. Data from a regional banking institution is used for the case analysis. These data indicate that African Americans are significantly more likely to be turned down for mortgage refinancing than their white American counterparts. We suggest that refinance discri‐mination is one contributing factor to the continuing wealth or net worth gaps between blacks and whites. The inability to access the potential capital resident in one's home impedes the ability of African Americans to transmit advantage from one generation to the next.     

Can cultural consumption increase future earnings? Exploring the economic returns to cultural capital

Cultural consumption is often viewed as a form of embodied cultural capital which can be converted into economic rewards (e.g., earnings) because such practices increase the likelihood of moving into more advantaged social positions. However, quantitative evidence supporting this theory remains uncertain because it is often unable to rule out alternative explanations. Cultural consumption appears to influence hiring decisions in some elite firms, in both the US and the UK, but it is unclear whether these processes are applicable to other professional occupations and other labour market processes, such as promotions. We examine these processes using data from Understanding Society, an individual‐level panel survey conducted in the UK, allowing us to explore whether cultural consumption predicts future earnings, upward social mobility and promotions. People who consume a larger number of cultural activities are more likely to earn higher wages in the future, to be upwardly socially mobile, and to be promoted. Cultural consumption, then, can function as cultural capital in some labour market settings, potentially contributing to the reproduction of income inequality between generations.     

The social gradient in cultural consumption and the information‐processing hypothesis

Patterns of cultural consumption have a strong social gradient which is primarily driven by education, but what explains these educational differences in cultural preferences remains unclear. Explanations based on information processing capacity have gained widespread currency; the perceived cognitive ‘difficulty’ of both appreciating high culture, and of maintaining broad, omnivorous tastes. If, on average, high culture is more complex than low culture then a higher level of information processing capacity may be required to derive enjoyment from it. In contrast, socialization theories suggest that exposure to ‘high’ culture, may explain this gradient, particularly among university graduates with degrees in the Arts or Humanities. To test these two theories we use the Cultural Capital and Social Exclusion survey (n = 1,079) and estimate the association between degree type and measures of cultural preference and consumption, including: film directors, artists, and cultural participation. Compared to non‐graduates, arts, humanities, and social science graduates are more likely to enjoy highbrow directors and artists, and are more likely to be cultural omnivores; while graduates from other subjects are not clearly distinct from non‐graduates in their cultural preferences. These findings suggest that information processing plays a minor role in shaping the social gradient in cultural consumption.
