Mark-specific hazard ratio model with missing multivariate marks

An objective of randomized placebo-controlled preventive HIV vaccine efficacy (VE) trials is to assess the relationship between vaccine effects to prevent HIV acquisition and continuous genetic distances of the exposing HIVs to multiple HIV strains represented in the vaccine. The set of genetic distances, only observed in failures, is collectively termed the ‘mark.’ The objective has motivated a recent study of a multivariate mark-specific hazard ratio model in the competing risks failure time analysis framework. Marks of interest, however, are commonly subject to substantial missingness, largely due to rapid post-acquisition viral evolution. In this article, we investigate the mark-specific hazard ratio model with missing multivariate marks and develop two inferential procedures based on (i) inverse probability weighting (IPW) of the complete cases, and (ii) augmentation of the IPW estimating functions by leveraging auxiliary data predictive of the mark. Asymptotic properties and finite-sample performance of the inferential procedures are presented. This research also provides general inferential methods for semiparametric density ratio/biased sampling models with missing data. We apply the developed procedures to data from the HVTN 502 ‘Step’ HIV VE trial.     

Informal practices and the street-level construction of migrant deportability: Chechen refugees and local authorities in Polish accommodation centres for asylum seekers

In a world of unprecedented mobility, an increasing number of migrants are confronted with policies that challenge their belonging and produce subordinate migrant inclusion. This article explores how the deportation regime saturated daily life in accommodation centres for asylum seekers in Eastern Poland, which acted as spaces of deportability that facilitated the deterritorialisation of European political space. Drawing on ethnographic fieldwork among Chechen refugees and local authorities, I argue that the street-level construction of deportability depends on an exchange between formal and informal practices and policies. Ethnographic data indicate that in the Polish centres, the deportation regime took both bureaucratic and non-bureaucratic forms. As street-level bureaucrats carried out their work duties in a way that reduced the scope of their power, the deportation regime relied on refugees to reproduce its disciplinary aspect.     

Multidimensional Quality of Life: A New Measure of Quality of Life in Adults

This paper presents a new measure for assessing quality of life (QOL) –the Multidimensional Quality of Life (MQOL)– and describes its derivation, characteristics, structure and several applications. Reasons for developing the MQOL include the restricted range of assessed domains and the heavy emphasis on health in many standard assessment tools. The MQOL was derived by meaning probes into QOL in different samples. It is a 60-item self-report tool of high reliability and validity covering various themes and forming, in line with factor and cluster analyses, 17 scales that constitute five factors according to confirmatory factor analysis. It has been applied with thousands of individuals, in English, Hebrew, Russian and Arabic, and is adequate for healthy and physically or mentally sick individuals, under regular or challenging circumstances. Described studies present findings in samples of sick or healthy individuals (e.g., unemployed, members of a collapsing Kibbutz); relations between the MQOL and coping strategies in partners of sick individuals; and interrelations of overall and scale scores in new and old immigrants. Conclusions focus on the structure of the MQOL, the specificity of coping effects, and the stabilizing mechanisms of QOL.     

Using categorical markers as auxiliary variables in log‐rank tests and hazard ratio estimation

Markers, which are prognostic longitudinal variables, can be used to replace some of the information lost due to right censoring. They may also be used to remove or reduce bias due to informative censoring. In this paper, the authors propose novel methods for using markers to increase the efficiency of log‐rank tests and hazard ratio estimation, as well as parametric estimation. They propose a «plug‐in» methodology that consists of writing the test statistic or estimate of interest as a functional of Kaplan–Meier estimators. The latter are then replaced by an efficient estimator of the survival curve that incorporates information from markers. Using simulations, the authors show that the resulting estimators and tests can be up to 30% more efficient than the usual procedures, provided that the marker is highly prognostic and that the frequency of censoring is high.     

Saving Performance in Individual Development Accounts: Does Marital Status Matter?

Research indicates that marriage has a large effect on reducing the risk of poverty and is associated with a higher probability of attaining affluence over the life course when compared with nonmarriage. Using data from the American Dream Demonstration (N =2,364), this study compares savings performances of married and unmarried low‐income participants in a matched savings program—Individual Development Accounts. The results indicate that both married and unmarried low‐income participants can save in Individual Development Accounts. After controlling for program and other participant characteristics, there were no significant differences in savings between married and unmarried participants. We further examined possible factors that are associated with Individual Development Account savings performance for these two groups.     

First-time mothers’ birth beliefs,preferences, and actual birth: A longitudinal observational study

Problem

Birth preferences, such as mode and place of birth and other birth options, have important individual and societal implications, yet few studies have investigated the mechanism which predicts a wide range of childbirth options simultaneously.

MARITAL QUALITY AMONG COUPLES LIVING UNDER THE THREAT OF FORCED RELOCATION: THE CASE OF FAMILIES IN THE GOLAN HEIGHTS

This study aims to explore how the long period of uncertainty about possible relocation affects the marital quality of the population in the Golan Heights and what forms of coping with this ongoing stress are used. The results, based on both quantitative and qualitative data, indicate a circular process in which the level of stress generated by the uncertainty varies with marital quality and with other personal and family resources, such as potency and an appreciation of the spouse's ability to cope with the stress. Four ways of coping with the uncertainty were observed in in-depth interviews: fighting, ignoring, postponing, and planning. The results are discussed in terms of their meaning for possible systemic interventions.     

Individual and Familial Determinants of Married Arab Israeli Women's Labor Force Participation: Trends of Change and Stability

Although the Arab population in Israel has undergone important economic and social changes in the past decades, the labor force participation of Arab women, particularly married women, has remained limited. This study uses census data to learn about the individual and familial factors associated with the entry into paid work of married Arab women and examines the extent to which these factors have changed over time. A major advantage is that the study distinguishes between the Muslim, Christian, and Druze populations, who markedly differ in their demographic, social, and cultural characteristics. Results from logistic regression models and standardization analyses reveal that the growth in employment experienced by Arab women was associated with the increasing education of both wives and husbands. However, the returns to education significantly decreased over time, particularly among Druze women, suggesting it has become more difficult for highly educated women to find employment. Results further show that the growth in employment experienced by Muslim and Christian women was related both to a decline in fertility and to a decrease in the negative returns to having children. Overall, findings underscore the structural barriers that limit Arab Israeli women's employment opportunities and raise concerns about their future occupational prospects.     

Combining Happines’s and Suffering in a Retrospective View of Anchor Periods in Life: A Differential Approach to Subjective Well-Being

The intersection of dimensions of subjective well-being (SWB) generates SWB types. We delineated SWB types by cross-tabulating happiness and suffering ratings that participants attributed to outstandingly meaningful periods in their life referred to as anchor periods. A sample of 499 older Israelis (age 58–94) was queried about two positive periods (the happiest, the most important) and two negative periods (the most miserable, the most difficult). A variety of variables discriminated between the more frequent congruous types of Happy (high happiness and low suffering) and Unhappy (low happiness and high suffering), but also presented the incongruous types of Inflated (high happiness and high suffering) and Deflated (low happiness and low suffering) as discriminable. Thus, women were more likely to be Inflated whereas men were more likely to be Deflated; low education related more to Happy in the happiest period and to Unhappy in the negative periods; present life satisfaction related more to Happy than to Unhappy in the positive, but not in the negative, periods; and Holocaust survivors were more likely to be Deflated and Unhappy in the negative, but not in the positive, periods. The study supported a differential perspective on SWB within people’s narratives of their lives. An erratum to this article is available at .     

Agriculture,communities, and new social movements: East European ruralities in the process of restructuring

This paper examines the usefulness of the new social movements (NSMs) paradigm in the changing context of East European post-communist societies and their agricultural systems and rural communities. Starting with statements formulated in Western sociology in the context of Western democratic societies about NSMs as a protest against modernity, the paper analyses the role of such movements in the still modernizing Eastern European reality. The first part of the paper briefly examines some basic elements of the NSMs paradigm in European and American social science. The goal of this section is not only to identify the basic characteristics of NSMs, but also to identify the typical frames used by them. The second part of the paper focuses on the presence of NSMs in the communist era. Drawing on the idea of NSMs as indicators of a ‘post-materialist shift’ as well as of ‘anti-establishment’ and ‘pro-participatory democracy’, the paper examines the frames of democratic opposition in Eastern Europe before 1989. The final part of the paper considers several selected examples from Poland, Hungary, and the Czech Republic to explore the role of NSMs in the process of shaping new ruralities during the post-communist transformation.
