On general consistency in deconvolution mode estimation

This paper addresses the problem of estimating the mode of a density function based on contaminated data. Unlike conventional methods, which are based on localizing the maximum of a density estimator, we introduce a procedure which requires computation of the maximum among finitely many quantities only. We show that our estimator is strongly consistent under very weak conditions, where not even continuity of the density at the mode is required; moreover, we show that the estimator achieves optimal convergence rates under common smoothness and sharpness constraints. Some numerical simulations are provided.     

Protective and Promotive Effects of Latino Early Adolescents' Cultural Assets Against Multiple Types of Discrimination

Given adversity associated with discrimination, it is important to identify culturally relevant factors that may protect against its harmful effects. Using latent variable interactions, this study examined the moderating effects of cultural assets on the association between multiple types of discrimination and adolescents' adjustment. Participants included 174 seventh‐ and eighth‐grade Latino adolescents (51% girls); majority were of Mexican origin. Peer discrimination was associated with higher internalizing symptoms, whereas cultural assets predicted higher academic motivation above and beyond racial–ethnic discrimination, demonstrating a promotive effect. Adolescents' Latino cultural assets also protected against higher levels of externalizing symptoms in the context of high peer discrimination and foreigner objectification. The discussion focuses on the conceptual and applied implications of these findings.     

THE REDUCTION OF RISKS FOR SET-VALUED ESTIMATORS

An extension of the Theorem of Rao-Blackwell will be given for the case of set-valued estimators, its images being nonempty, compact-convex subsets of a certain Banach space. Moreover sufficiency will be characterized in connection with set-valued estimators by related point-valued functions.     

The experience of trauma recovery: a qualitative study of participants in the Women Recovering from Abuse Program (WRAP)

The efficacy of intensive group treatment programs for child maltreatment has been established. The aim of this qualitative study was to understand how women with a history of child maltreatment experienced the Women Recovering from Abuse Program (WRAP), an existing intensive group treatment program. Seven women were interviewed following their participation in WRAP. Three themes emerged: Breaking Trauma-Based Patterns, Doing Therapy, and The Healing Journey as a Continuous Process. These findings deepen our understanding about how participants view the recovery process. Theoretical and clinical implications are discussed.     

Lifespan Variation by Occupational Class: Compression or Stagnation Over Time?

Cross-sectional analyses of adult lifespan variation have found an inverse association between socioeconomic position and lifespan variation, but the trends by social class are unknown. We investigated trends in lifespan variation over four decades (1971–2010) by occupational social class (manual, lower nonmanual, upper nonmanual, other) using Finnish register data. We performed age and cause-of-death decompositions of lifespan variation for each sex (a) by occupational class over time and (b) between occupational classes at a shared level of life expectancy. Although life expectancy increased in all classes, lifespan variation was stable among manual workers and decreased only among nonmanual classes. These differences were caused by early-adult mortality: older-age lifespan variation declined for all the classes, but variation in early-adult mortality increased for all classes except the highest. The manual class’s high and stagnant lifespan variation was driven by declines in circulatory diseases that were equally spread over early mortality-compressing and older mortality-expanding ages, as well as by high early-adult mortality from external causes. Results were similar for men and women. The results of this study, which is the first to document trends in lifespan variation by social class, suggest that mortality compression is compatible with increasing life expectancy but currently achieved only by higher occupational classes.     

Immigrant Fertility: A Comparative Study between Italy and Russia

In this paper, we contribute to the analysis of fertility differentials between female migrants and the native‐born by examining the transition to first child using event history analysis. We use event history as a quantitative translation of the life‐course approach. The data examined are the Italian Families and Social Subjects (FSS) survey, conducted in 2003, and the Russian Parents and Children, Men and Women in Family and Society survey, conducted in 2004. We examine the data sets separately and contrast the results. The objective of the study is twofold. First, we seek to determine whether differences exist in the decision and timing of childbearing between native and immigrant women in Italy and in Russia. Second, we aim to compare the experiences of immigrants in the two countries, to determine whether there may be any commonalities inherent to the immigrant populations despite moving into widely different contexts. Our results suggest that the age profiles and marital status similarly affect the immigrant regardless of whether she is migrating to Russia or to Italy. In Italy, educational attainment is positively correlated with first‐birth intensities for immigrants – the opposite of what is observed for the native‐born. In Russia, education is not a significant determinant for immigrants. This leads us to the following conclusion: the similarity in the risk profiles of our immigrants into vastly different country contexts is more suggestive of immigrants following a distinct life course, with common risk profiles for bearing their first child, than assimilating or conforming to the native fertility patterns. Social capital in particular may play a different role in determining fertility patterns for immigrants, as it does for the native‐born.     

PRIVACY PROTECTION STRATEGIES ON FACEBOOK

The privacy paradox describes people's willingness to disclose personal information on social network sites despite expressing high levels of concern. In this study, we employ the distinction between institutional and social privacy to examine this phenomenon. We investigate what strategies undergraduate students have developed, and their motivations for using specific strategies. We employed a mixed-methods approach that included 77 surveys and 21 in-depth interviews. The results suggest that, in addition to using the default privacy settings, students have developed a number of strategies to address their privacy needs. These strategies are used primarily to guard against social privacy threats and consist of excluding contact information, using the limited profile option, untagging and removing photographs, and limiting Friendship requests from strangers. Privacy strategies are geared toward managing the Facebook profile, which we argue functions as a front stage. This active profile management allows users to negotiate the need for connecting on Facebook with the desire for increased privacy. Thus, users disclose information, because they have made a conscious effort to protect themselves against potential violations. We conclude that there is a tilt toward social privacy concerns. Little concern was raised about institutional privacy and no strategies were in place to protect against threats from the use of personal data by institutions. This is relevant for policy discussions, because it suggests that the collection, aggregation, and utilization of personal data for targeted advertisement have become an accepted social norm.     

Walk the line: Active Moms define corporate social responsibility

While many have suggested that corporate social responsibility is in part a response to stakeholders, little research has been done that gives primacy to the targeted publics’ voice, interpretations, and responses to corporate social responsibility. This research examines the meaning and attributes that Active Moms, an often targeted stakeholder group, assign to corporate social responsibility. In nine focus groups (N = 72), participants suggested that authentic CSR (a) is a combination of socially responsible business practices and campaigns to engage issues which impact their lives, (b) must be marked by longevity and consistency, (c) makes the most sense when linked to core business practices, (d) is distinct from philanthropy, and (e) is evaluated using a blend of rationality and emotionality.
