Resampling-based Classification Using Depth for Functional Curves

The depths, which have been used to detect outliers or to extract a representative subset, can be applied to classification. We propose a resampling-based classification method based on the fact that resampling techniques yield a consistent estimator of the distribution of a statistic. The performance of this method was evaluated with eight contaminated models in terms of Correct Classification Rates (CCRs), and the results were compared with other known methods. The proposed method consistently showed higher average CCRs and 4% higher CCR at the maximum compared to other methods. In addition, this method was applied to Berkeley data. The average CCRs were between 0.79 and 0.85.     

Defining Women's Global Political Empowerment: Theories and Evidence

Although women's access to political power has increased tremendously, nowhere are women equal to men in their influence over and exercise of political authority. Scholarship on women's political empowerment is uneven and incomplete. This article interrogates ‘women's political empowerment’, considering its definition, measurement, and application. First, we establish that academics and practitioners have not articulated a clear definition of women's political empowerment. To fill this gap, we put forward a new definition that conceptualizes women's political empowerment as a transformative process. We then review existing social science literature on women's political empowerment. We argue that scholars must expand research to develop a broader vision of women's political empowerment and develop measures that capture this breadth.     

Ask Prices, Offers, and Time to Sale in an Online Exchange

By examining an online computer exchange, we find that sellers who place higher nonbinding ask prices have higher outstanding offers and remain on the exchange longer, suggesting a willingness to hold out for higher offers. Additionally, higher ask prices deter buyers from making offers. The results are stronger in thinner market segments, suggesting that gains from waiting for a high price are greater when buyers' tastes are idiosyncratic. These relationships are consistent with models in which buyers engage in costly search and suggest that online exchanges may not eliminate the frictions related to bilateral transactions.     

Factitious Illness by Proxy: Understanding Underlying Psychological Processes and Motivations

Children are put at risk of emotional and physical harm when parents seek unnecessary medical care. Understanding why parents seek medical interventions that create risk for their children requires us to consider how past experiences, and the mental representations of these experiences influence current behaviour. Past experiences of danger affect how parents interpret ‘dangerous’ situations in the present and how they organise protection of their child. This article demonstrates how the notion of mental representations (that dispose parents to act in particular ways) can assist in engaging, assessing and treating parents who display factitious illness by proxy behaviour. When classified using the Dynamic‐Maturational Method, the Adult Attachment Interview (AAI) allows both assessment of implicit and explicit representations and also understanding of the developmental process through which parents have learnt to attribute meaning to information and to organise their behaviour. In this case study, psychosocial assessment of the family included an AAI with each parent. The use of this assessment tool both aided the therapy team in the process of case formulation and intervention planning, and had therapeutic value in and of itself. We argue that treatment is more likely to be effective if the parents and professionals have a shared understanding of the parents' intentions and the developmental process that led to unsafe behaviour, which requires change.     

Determinants of contraceptive switching behavior in rural Sri Lanka

This study examines the influence of a selected set of determinants of contraceptive method switching in rural Sri Lanka. Of interest is the question of how change in contraceptive practice at the individual level can account for patterns observed at the aggregate level. Based on calendar data on contraceptive use over a 3-year period, collected for more than 3,000 married women in a 1986 survey, the multivariate analysis shows that women who attain all or a significant proportion of their desired fertility tend to switch to more effective methods. Women who experience method failure tend to switch methods, usually to a type that is more effective. The woman's background determinants of age and education have small but significant effects on method switching, whereas the effect of household economic well-being is not significant. There is strong indication that rural couples are practicing contraception in a nonrandom fashion, switching methods in accordance with changes in their fertility motivations and contraceptive experience.     

Revisiting the Work Ethic in America

Starting with a reflection on the September 11th, 2001, terrorist attacks on the Pentagon and the World Trade Center and the corporate fraud and bankruptcies of 2002, the authors provide an overview of the professional literature concerning the origins, evolution, practice, and future implications of the work ethic in the United States. Discussion focuses on the American work ethic from both a historical and a modern‐day perspective, highlighting the formation of what is now considered a major paradigm of work; views on the changing nature of the work ethic, especially for women and members of minority groups; and implications for career counselors.
