A marginalized diffusion model for estimating age at first lower endoscopy use from current status data

Summary.  We propose an approach for estimating the age at first lower endoscopy examination from current status data that were collected via two series of cross-sectional surveys. To model the national probability of ever having a lower endoscopy examination, we incorporate birth cohort effects into a mixed influence diffusion model. We link a state-specific model to the national level diffusion model by using a marginalized modelling approach. In future research, results from our model will be used as microsimulation model inputs to estimate the contribution of endoscopy examinations to observed changes in colorectal cancer incidence and mortality.     

An improved class of estimators for the population mean

Starting from the Rao (Commun Stat Theory Methods 20:3325–3340, 1991) regression estimator, we propose a class of estimators for the unknown mean of a survey variable when auxiliary information is available. The bias and the mean square error of the estimators belonging to the class are obtained and the expressions for the optimum parameters minimizing the asymptotic mean square error are given in closed form. A simple condition allowing us to improve the classical regression estimator is worked out. Finally, in order to compare the performance of some estimators with the regression one, a simulation study is carried out when some population parameters are supposed to be unknown.     

Testing the Comparability of Different Types of Social Indicators Across Groups

The social indicator movement has realized a considerable increase in importance during the last 50 years. This happened not the least by the publications in the journal Social Indicators Research. Social indicators have been developed for many aspects of life. The scores on these indicators often are compared through time and across groups. An essential requirement for such research is that the measures used are comparable through time and across groups. The comparability through time is not such a big problem but the comparability of measures across groups is not so obvious. This requires harmonization of indicators based on objective variables and invariance testing for indicators based on subjective and objective variables. In this paper we discuss how the comparability of different types of social indicators based on subjective and objective variables can be tested using invariance testing. This is a relevant issue because the existing testing procedure is designed for only one type of social indicators and this test is not directly applicable on the other types of social indicators.     

Measurement Invariance in Multilingual Survey Research: The Role of the Language of the Questionnaire

This paper examines whether or not survey measures asked to two linguistic groups exhibit invariance within a country. It tests configural, metric and scalar invariance in a model that distinguishes the response component and the cognitive component of the measurement process using survey items. Our findings show that when differences in the response process are allowed, concepts are (partially) invariant across groups. The analysis is conducted for items measuring some aspects of political trust and satisfaction with politics for six linguistic groups including French, Dutch, Estonian, German, Ukrainian and Russian in four countries. Data comes from the European Social Survey.     

A political-economic theory of relevance: Explaining climate change inaction

Why have societies failed to effectively respond to climate change? We address the question of climate change inaction by (1) examining how an unambiguously ominous report about climate change (IPCC 2018) was made palatable by news media and (2) explaining why climate change is typically unthematized in everyday life. Drawing on Adorno and Schutz, we develop a political-economic theory of relevance. The imperative to accumulate capital is not only a social-structural reality but also shapes why particular facts are regarded as relevant in experience (topical relevance) as well as how relevant material is interpreted (interpretative relevance) and acted toward (motivational relevance). Applying this framework, we (1) argue that media popularizations of the IPCC's dire Global Warming of 1.5°C (2018) are constituted by relevance systems conditioned by a capitalist social context and (2) strengthen Ollinaho's (2016) Schutzian explanation for climate change inaction by examining how productive relations and the culture industry perpetuate climate change irrelevance in everyday life. Schutz's framework helps conceptualize the intricacies of ideology and, when revised with Adorno's sociology, shines new light on an old question: the relations between social conditions and knowledge.     

Older Adolescents’ Understanding of Participant Rights in the BlackBerry Project,a Longitudinal Ambulatory Assessment Study

For a long‐term, longitudinal study that used BlackBerry smartphones for passive ambulatory assessment among older adolescents, this study focused on three areas of ethical concern: (1) adolescents’ competence to give assent; (2) understanding of confidentiality, the protection of information, and project goals; and (3) awareness of procedures and benefits, and comfort with the research design. One hundred and seventy‐eight participants were 17 and 18 years old (84 girls). Results suggested that participants freely gave consent and understood most, but not all of the informed consent information. Participants reported a high level of satisfaction. Participants showed less understanding of when their confidentiality would be broken and how data would be protected.     

Toward an organic policy sociology

According to many, sociology is facing a crisis of relevance. Of particular concern is sociology's inability to impact policy. Sociologists, who should be the go‐to on major policy issues have been sidelined as other social scientists take up roles as policy advisors. Recent efforts aimed at encouraging public engagement have focused on disseminating research and producing more policy‐relevant knowledge. These are welcome resources, but they reflect a deep ambivalence toward policy sociology and a tendency to conflate participation in public discussions with policy impact. In contrast, this essay draws on recent findings about the power of policy experts to develop an organic policy sociology. Organic policy sociology depends on co‐designing and carrying out research with policymakers with whom we share critical and professional commitments. By working collaboratively with policymakers, sociologists can foster equity‐promoting policy, change how policymakers understand social problems, and improve how citizens experience policy on the ground. To that end, I offer six orienting strategies for developing and maintaining organic policy sociology projects, from finding the right partner to assessing the impact of our work.     

Wandel von Arbeit — Wandel von Männlichkeiten

Whereas the current public interest in the relation of transformation of paid work and gender is focused a lot on men and masculinities, sociological analysis is mostly focused on women and feminity. Few studies on work and masculinity suggest that with the erosion of industrial working conditions traditional constructions of masculinity are challenged to the core. It is our thesis that three mechanisms are working in stabilizing the relationship between paid work and masculinity: reconfigured standard employment relationship, entrepreneurial self, and hegemonic masculinity. Supposably, the new adjusted social order opens a range between two poles: the adherence to traditional patterns of masculinity on the one hand, which tends do enforce insecurity, and a pattern of hegemonic masculinity on the other side, which is characterized by a proactive and positive attitudes of dealing with present tendencies of uncertainty, seeing change as chance of creating.     

The Effects of Contingent Caregiver Imitation of Infant Vocalizations: a Comparison of Multiple Caregivers

The present study replicated and extended the Pelaez et al. (Journal of Applied Behavior Analysis 44:33–40, 2011) study, which examined the reinforcing effects of mothers’ contingent imitation of their infants’ vocalizations. Three infants aged 7–12 months who could vocalize sounds but not words participated with two caregivers for each infant (i.e., triads). During the intervention phase, the caregivers were asked to immediately imitate all vocalizations emitted by the child for a 3-min period. During the yoked control phase, the caregivers listened to an audio recording from the preceding condition and provided vocalizations non-contingently on the infants’ responses. The procedures yielded different results across participants; one infant emitted a higher frequency of vocalizations during the contingent imitation phases over the control phases, and the other two infants showed higher rates of responding during the control phases. However, all infants emitted more imitative return vocalizations during contingent reinforcement conditions compared with the yoked control condition.
