A DIRECT TEST OF THE EFFICIENT MARRIAGE MARKET HYPOTHESIS

This paper takes Becker's efficient marriage market hypothesis at face value, and directly confronts it with data from Hong Kong. The theory of optimal assignment is used to develop an empirical model of spouse selection, which resembles a Tobit model. This model can address positive or negative assortative matching as well as marginal product pricing in marriage markets. We also use a computer algorithm to solve the assignment problem for imputed marital output. The degree to which the actual pairing of husbands and wives corresponds to the optimal pairing provides a goodness-of-fit test of the efficient marriage market hypothesis.

Bank Loan Officers' Perceptions of Business Owners: The Role of Gender

There is a widely held belief that banks may be discriminating against female business owners. This study was designed to explore the perceptions held by bank loan officers of male and female business owners, using Bourdieu's theory of practice and Kelly's personal construct methodology. The research literature might lead to an expectation that the characteristics of the business owners would be relatively homogenous but that men and women business owners would be construed differently (for example women might be seen to lack drive). However, the results demonstrate heterogeneity in the constructs held by bank loan officers, and a particular concern with the character of the business owner. Significant gender differences were observed in only 20 of the 325 constructs elicited from 35 bank loan officers. Female bank loan officers were as likely as male bank loan officers to draw gender distinctions between business owners. Detailed multivariate analyses confirmed no evidence of systematic gender differences in the constructs held by bank loan officers of business owners.     

Mixture structure analysis using the Akaike Information Criterion and the bootstrap

Given i.i.d. observations x1,x2,x3,...,xn drawn from a mixture of normal terms, one is often interested in determining the number of terms in the mixture and their defining parameters. Although the problem of determining the number of terms is intractable under the most general assumptions, there is hope of elucidating the mixture structure given appropriate caveats on the underlying mixture. This paper examines a new approach to this problem based on the use of Akaike Information Criterion (AIC) based pruning of data driven mixture models which are obtained from resampled data sets. Results of the application of this procedure to artificially generated data sets and a real world data set are provided.     

Evaluating Application Service Provisioning Using System Dynamics Methodology

Despite the hype surrounding the value‐added potential of e‐business for contemporary firms, the recent technology downturn was marked by poor customer satisfaction from investment in e‐business initiatives. An apparent mismatch between customer expectations and vendor offerings suggested a lack of appropriate methods and techniques for evaluating e‐business. This article draws from a longitudinal research study on the deployment, hosting and integration of application service provisioning (ASP), an e‐business model targeted mainly at small and medium‐sized businesses (SMBs). Using system dynamics as a methodology that addresses the inherent complexity of the ASP model, the article demonstrates how a series of complex inter‐relationships between key performance indicators (KPIs) will impact the business value for customers from ASP vendor products and services. The lessons from this research will be particularly relevant for existing and future ASP vendors and customers.     

Adoption and Antisocial Personality: Genetic and Environmental Factors Associated with Antisocial Outcomes

The present review critically evaluates evidence from adoption studies on the heritability of antisocial personality, interactions between genetic predispositions and the characteristics of adoptive mothers and fathers, and both the methodological and diagnostic shortcomings of existing studies. The article concludes with directions and suggestions for future research and practice.     

The Changing Institution of Marriage: Adolescents’ Expectations to Cohabit and to Marry

Cohabitation has become part of the pathway toward marriage. Prior work focuses on expectations to marry and has ignored cohabitation. Although most young adults are not replacing marriage with cohabitation, but instead cohabit and then marry, it is important to study adolescents’ joint expectations to cohabit as well as marry. Our analyses draw on recently collected data from the Toledo Adolescent Relationships Study (N = 1,293). We find that adolescents are less certain about their cohabitation than marriage expectations. Dating and sexual experience, traditional values, prosocial activities, and parents influence adolescents’ union formation expectations. The findings from this work suggest that adolescents are including cohabitation as part of their future life trajectories but rarely envision cohabitation as substituting for marriage.     

Social Work Field Educators' Views on Student Specific Learning Needs

Each year a significant proportion of students withdraw from placement in time to avoid penalty, while others fail. This article reports on a small field education research project that identified common learning issues for first placement students. Eighteen experienced supervising field educators (FEs), participated in semi structured focus groups, and identified repeat areas of difficulty in student learning that they had managed as supervisors. They also identified strategies that had been efficacious in supporting student learning. The research undertaken in 2010–2011 identified three specific themes relating to difficulties in student learning: specific student characteristics that required additional support; the university/FE partnership; student proficiency in using supervision. The findings suggest that a students' right to privacy must be considered in the provision of educational support, and that support is most effective when there is a strong partnership between the FE and university. In addition, further development of field education pedagogy may be needed to embed theory and skills related to the use of supervision and reflective learning.     

Practising family history: ‘identity’ as a category of social practice

Research on family history argues it performs the task of anchoring a sense of ‘self’ through tracing ancestral connection and cultural belonging, seeing it as a form of storied ‘identity‐work’. This paper draws on a small‐scale qualitative study to think further on the identity‐work of family history. Using practice theory, and a disaggregated notion of ‘identity’, it explores how the storying of family histories relates to genealogy as a leisure hobby, a form of historical research, and an information‐processing activity; and examines the social organization of that narrativity, where various practical engagements render certain kinds of genealogical information more, or less, ‘storyable’. Key features of ‘identity‐work’ in family history, such as the construction of genealogy as a personal journey of discovery and identification with particular ancestors, emerge as a consequence of the procedures of family history, organized as a set of practical tasks. The paper explores ‘identity‐work’ as a consequence of people's engagement in specific social practices which provide an internal logic to their actions, with various components of ‘identity’ emerging as categories of practice shaped within, and for, use. Focusing on ‘identity’ as something produced when we are engaged in doing other things, the paper examines how the practical organization of ‘doing other things’ helps produce ‘identity’ in particular ways.     

Gender and Casual Sexual Activity From Adolescence to Emerging Adulthood: Social and Life Course Correlates

The prevalence of casual sexual activity among teens and emerging adults has led to much public attention. Yet limited research has investigated whether the number of casual sexual partners per year changes as heterosexual men and women transition from adolescence into emerging adulthood. We considered the influence of social context and life course factors on the number of casual sex partners. We examined four waves of interviews from the Toledo Adolescent Relationships Study (TARS) and used negative binomial growth curve models to investigate patterns of change in the number of casual sex partners (N = 1,196) ages 15 to 22. Men and women both reported increases in the number of casual sex partners over time and did not differ from each other in the rate of change over time. In all, 40% of respondents reported a recent casual sex partner at age 22. Number of prior dating relationships, education status, substance use, and perceptions of peer sexual behavior significantly influenced the number of casual sex partners. Emerging adults who did not complete high school, compared to those enrolled in four-year degree programs, reported significantly more partners. The findings contribute to research on intimate relationships and provide insights for programs targeting emerging adults.     

Manager Characteristics and Employee Job Insecurity around a Merger Announcement: The Role of Status and Crossover

Most existing research theorizes individual factors as predictors of perceived job insecurity. Incorporating contextual and organizational factors at an information technology organization where a merger was announced during data collection, we draw on status expectations and crossover theories to investigate whether managers' characteristics and insecurity shape their employees' job insecurity. We find having an Asian as opposed to a White manager is associated with lower job insecurity, whereas managers' own insecurity positively predicts employees' insecurity. Also contingent on the organizational climate, managers' own tenure buffers, and managers' perceived job insecurity magnifies insecurity of employees interviewed after a merger announcement, further specifying status expectations theory by considering context.
