Missing Data in Sociological Research: An Overview of Recent Trends and an Illustration for Controversial Questions, Active Nonrespondents and Targeted Samples

In an age of telemarketers, spam emails, and pop-up advertisements, sociologists are finding it increasingly difficult to achieve high response rates for their surveys. Compounding these issues, the current political and social climate has decreased many survey respondents’ likelihood of responding to controversial questions, which are often at the heart of much research in the discipline. Here we discuss such implications for survey research in sociology using: a content analysis of the prevalence of missing data and survey research methods in the most cited articles in top sociology journals, a case study highlighting the extraction of meaningful information through an example of potential mechanisms driving the non-random missing data patterns in the Religion Among Academic Scientists dataset, and qualitative responses from non-responders in this same case. Implications are likely to increase in importance given the ubiquitous nature of survey research, missing data, and privacy concerns in sociological research.     

Operations Risk Management: Overview of Paul Kleindorfer's Contributions

This paper reviews Paul Kleindorfer's contributions to Operations Management (OM), with a special focus on his research on risk management. An annotated bibliography of selected other contributions reviews the breadth of topics that have occupied Kleindorfer's research attention over his now 45 + years of research. These include optimal control theory, scheduling theory, decision sciences, investment planning and peak load pricing, plus a number of important applications in network industries and insurance. In the area of operations risk management, we review recent work that Kleindorfer and his colleagues in the Wharton Risk Center have undertaken on environmental management and operations, focusing on process safety and environmental risks in the chemical industry. This work is directly related to Kleindorfer's work in the broader area of “sustainable operations”, which he, Kal Singhal and Luk Van Wassenhove recently surveyed as part of the new initiative at POMS to encompass sustainable management practices within the POMS community. Continuing in the area of supply chain risks, the paper reviews Kleindorfer's contributions to the development of an integrated framework for contracting and risk hedging for supply management. The emphasis on alignment of pricing, performance and risk management in this framework is presaged in the work undertaken by Kleindorfer and his co‐authors in the 1980s on after‐sales support services for high‐technology products. This work on supply chain risk, and its successors, is reviewed here in light of its growing importance in managing the unbundled and global supply chains characteristic of the new economy.     

A comparison of models for clustered binary outcomes: analysis of a designed immunology experiment

The lymphocyte proliferative assay (LPA) of immune competence was conducted on 52 subjects, with up to 36 processing conditions per subject, to evaluate whether samples could be shipped or stored overnight, rather than being processed on fresh blood as currently required. The LPA study resulted in clustered binary data, with both cluster level and cluster-varying covariates. Two modelling strategies for the analysis of such clustered binary data are through the cluster-specific and population-averaged approaches. Whereas most research in this area has focused on the analysis of matched pairs data, in many situations, such as the LPA study, cluster sizes are naturally larger. Through considerations of interpretation and efficiency of these models when applied to large clusters, the mixed effect cluster-specific model was selected as most appropriate for the analysis of the LPA data. The model confirmed that the LPA response is significantly impaired in individuals infected with the human immunodeficiency virus (HIV). The LPA response was found to be significantly lower for shipped and overnight samples than for fresh samples, and this effect was significantly stronger among HIV-infected individuals. Surprisingly, an anticoagulant effect was not detected.     

Self-protection and insurance with interdependencies

We study optimal investment in self-protection of insured individuals when they face interdependencies in the form of potential contamination from others. If individuals cannot coordinate their actions, then the positive externality of investing in self-protection implies that, in equilibrium, individuals underinvest in self-protection. Limiting insurance coverage through deductibles or selling “at-fault” insurance can partially internalize this externality and thereby improve individual and social welfare.

The Timing of Cohabitation and Engagement: Impact on First and Second Marriages

Using a multistate sample of marriages that took place in the 1990s, this study examined associations between premarital cohabitation history and marital quality in first (N = 437) and second marriages (N = 200) and marital instability in first marriages (intact N = 521, divorced N = 124). For first marriages, cohabiting with the spouse without first being engaged or married was associated with more negative interaction, higher self‐reported divorce proneness, and a greater probability of divorce compared to cohabiting after engagement or marriage (with patterns in the same direction for marital positivity). In contrast, there was a general risk associated with premarital cohabitation for second marriages on self‐reported indices of marital quality, with or without engagement when cohabitation began.     

Multidimensional Family Therapy: A Science‐Based Treatment System

MDFT is a family‐based intervention for adolescent substance abuse and associated mental health and behavioural problems (Liddle, 2010). Integrative in several ways, MDFT uses an ecological or contextual conceptual framework to understand the developmental tasks of teens and their families. Research‐derived knowledge about risk and protective factors, and proximal causes, correlates and contributors to adolescent drug and related problems inform clinical thinking and interventions with every case. A multisystems approach, MDFT assesses and intervenes in four areas: (1) the adolescent as an individual and a member of a family and peer network; (2) the parent(s), both as individual adults and in his or her role as mother; father or caregiver; (3) the family environment and family relationships, as manifested in day‐to‐day family transactional patterns; and (4) extrafamilial sources of influence such as peers, school and juvenile justice. Interventions are made within and coordinated across domains. Progress in one area or with one person has implications for and use in others. Individual meetings with parent(s) and teen set the stage for family sessions, and family meetings may offer content and new outcomes that need to be brought to extrafamily meetings with juvenile justice or school personnel. MDFT was developed and tested as a treatment system rather than a one‐size‐fits‐all approach. A treatment system offers different versions of a clinical model that vary according to factors such as clinical sample characteristics (older versus younger adolescents, juvenile justice involved versus no involvement in juvenile justice systems), and treatment parameters (type of clinical setting and treatment dose).     

The relationship between adverse childhood experiences,health and life satisfaction in adults with care experience: The mediating role of attachment

Adverse childhood experiences (ACEs) are associated with a plethora of negative outcomes. Research has also found that adults who were separated from parental care and lived in alternative care settings during childhood have high levels of ACEs and are more likely to have poor outcomes. A growing body of research has supported the importance of attachment as a mechanism underlying the relationship between ACEs and adult wellbeing. However, little work has examined the role that attachment may play in the outcomes of adults who resided in residential and foster care during childhood. The current study examined the role of attachment avoidance and anxiety in the associations between ACEs and mental health, physical health, and life satisfaction in a sample of 529 adults with alternative care experience from 11 nations. Attachment avoidance partially mediated the relationship between ACEs and life satisfaction, mental health, and physical health. Attachment anxiety partially mediated the relationship between ACEs and life satisfaction and mental health, but not physical health. Taken together, the present study suggests that both attachment anxiety and avoidance play important, but unique, roles in understanding the relationship between ACEs and health and wellbeing for adults with care experience. Implications and limitations are discussed.

When Queerness Meets Intersectional Thinking: Revolutionizing Parallels,Histories, and Contestations

ABSTRACT

Intuitively distinguishing the myriad of critically informed paradigms requires an in-depth analysis of genealogies, histories, and philosophical underpinnings grounding each paradigm. Despite significant parallels between queer theory and intersectionality theory, the distinction of these two paradigms acts in both complicated and complementary manners that necessitate a dialogue on the contributions emanating from both paradigms to LGBTQ studies. This article targets the following goals: (1) explicate genealogy, history, and philosophical tenets of intersectionality and queer theory; (2) dialogue about the complementary yet complex relationships between the two paradigms; and (3) illustrate the promise of the complex relationship and distinction for LGBTQ studies.
