Qualitative Approaches to the Study of Thriving: What Can Be Learned?

Using the data from two ongoing studies of resilience and thriving, one of gay men growing up in heterosexist environments, the other of women living with AIDS, we review how qualitative approaches have enabled researchers to grapple with conceptual, methodological, and ethical dilemmas related to the study of resilience and thriving. We discuss the implications our values as researchers have on determining who is thriving; the powerful social, cultural, and political contexts that must be considered when investigating the effects of and resistance to adversity; and the implications of conceptualizing thriving as a process. Finally, we consider the opportunities opened up by qualitative analysis and suggest some avenues for future research.     

Successful aging: how does physical activity influence engagement with life?

With the increasing number of individuals over the age of 65?years worldwide, it is critical for society to recognize the importance of helping seniors maintain their health, physical, and cognitive functioning as well as their engagement with life. These three dimensions provide the foundation for successful aging (SA). The positive role of engagement with life has been understated to date in the literature. This review highlights the components of SA with particular emphasis on engagement and how physical activity positively impacts engagement which in turn positively influences health and physical function.     

A Quarter Century of The Analysis of Verbal Behavior: An Analysis of Impact

The Analysis of Verbal Behavior (TAVB) has been published since 1982, and during this time, interest in verbal behavior research appears to have increased substantially within behavior analysis. The purpose of the present analysis was to assess the influence of TAVB on the field by (a) counting citations of TAVB articles in the Journal of the Experimental Analysis of Behavior (JEAB) and the Journal of Applied Behavior Analysis (JABA) from 1983 through 2007, (b) examining which other journals cite TAVB, and (c) calculating impact-factor estimates for 2003 through 2007. Citations of TAVB articles began to appear in JEAB and JABA in the late 1980s to early 1990s, and by the end of 2007, almost a third of all articles published in TAVB had been cited in either JEAB or JABA. Other journals that cite TAVB include The Behavior Analyst and The Psychological Record. The estimated impact factor ranged from 0.267 to 0.600. Strategies for increasing the impact of TAVB are discussed.     

Sexual orientation at work: Documenting and understanding wage inequality

A growing body of research focuses on the labor market experiences and outcomes of LGBTQ+ people. Yet sexual orientation has been incorporated unevenly into research on labor market inequality, developing in parallel across work in labor economics and the sociology of work and organizations. In this review, we describe research on sexual orientation and wage inequality, bridging insights from quantitative studies of wage gaps and qualitative work on the organizational and occupational experiences of sexual minorities. We further discuss theoretical developments in the sociology of sexuality to provide background to the concepts and measures both bodies of research employ in practice. We argue that future research should integrate these approaches to consider how local and diffuse cultural understandings of sexual orientation shape the valuation of workers.     

Has Income Segregation Really Increased? Bias and Bias Correction in Sample-Based Segregation Estimates

Several recent studies have concluded that residential segregation by income in the United States has increased in the decades since 1970, including a significant increase after 2000. Income segregation measures, however, are biased upward when based on sample data. This is a potential concern because the sampling rate of the American Community Survey (ACS)—from which post-2000 income segregation estimates are constructed—was lower than that of the earlier decennial censuses. Thus, the apparent increase in income segregation post-2000 may simply reflect larger upward bias in the estimates from the ACS, and the estimated trend may therefore be inaccurate. In this study, we first derive formulas describing the approximate sampling bias in two measures of segregation. Next, using Monte Carlo simulations, we show that the bias-corrected estimators eliminate virtually all of the bias in segregation estimates in most cases of practical interest, although the correction fails to eliminate bias in some cases when the population is unevenly distributed among geographic units and the average within-unit samples are very small. We then use the bias-corrected estimators to produce unbiased estimates of the trends in income segregation over the last four decades in large U.S. metropolitan areas. Using these corrected estimates, we replicate the central analyses in four prior studies on income segregation. We find that the primary conclusions from these studies remain unchanged, although the true increase in income segregation among families after 2000 was only half as large as that reported in earlier work. Despite this revision, our replications confirm that income segregation has increased sharply in recent decades among families with children and that income inequality is a strong and consistent predictor of income segregation.     

High Rates of Access to Health Care,Disclosure of Sexuality and Gender Identity to Providers Among House and Ball Community Members in New York City

The House and Ball community is an important cultural manifestation of resiliency for Black and Latino gay and bisexual men and transgender women. Participants at the August 2013 House of Latex Ball in New York City were surveyed about insurance coverage, health care access, experiences in health care, and housing instability. The sample (n = 367) was 58% Black/African American and 20% Hispanic/Latino, with a mean age of 31. Fifty-five percent were gay and bisexual men. Although only 6% identified as transgender, nearly one half were gender nonconforming. Strong majorities had health insurance, were in regular medical care, and were “out” to their providers. Some were unstably housed and had recently exchanged sex for shelter or money. High rates of health care access and disclosure indicate resiliency and agency. Unstable housing and income insecurity may be structural drivers of vulnerability for this population to HIV infection and other health risks.     

A note on the annihilation number and 2-domination number of a tree

In 2014, Desormeaux et al. (Discrete Math 319:15–23, 2014) proved a relationship between the annihilation number and 2-domination number of a tree. In this note, we provide a family of bounds for the 2-domination number of a tree based on the amount of vertices of small degree. This family of bounds extends current bounds on the 2-domination number of a tree, and provides an alternative proof for the relationship between the annihilation number and the 2-domination number of a tree that was shown by Desormeaux et al.     

Optimal Policies for Selling New and Remanufactured Products

Because of environmental and economic reasons, an increasing number of original equipment manufacturers (OEMs) nowadays sell both new and remanufactured products. When both products are available, customers will buy the one that gives them a higher (and non‐negative) utility. Thus, if the firm does not price the products properly, then product cannibalization may arise and its revenue may be adversely impacted. In this paper, we study the pricing problem of a firm that sells both new and remanufactured products over a finite planning horizon. Customer demand processes for both new and remanufactured products are random and price‐sensitive, and product returns (also called cores) are random and remanufactured upon receipt. We characterize the optimal pricing and manufacturing policies that maximize the expected total discounted profit. If new products are made‐to‐order (MTO), we show that when the inventory level of remanufactured product increases, the optimal price of remanufactured product decreases while the price difference between new and remanufactured products increases; however, the optimal selling price of new product may increase or decrease. If new products are made to stock (MTS), then the optimal manufacturing policy is of a base‐stock policy with the base‐stock level decreasing in the remanufactured product inventory level. To understand the potential benefit in implementing an MTO system, we study the difference between the value functions of the MTO and MTS systems, and develop lower and upper bounds for it. Finally, we study several extensions of the base model and show that most of our results extend to those more general settings.     

The influence of motherhood on income: do partner characteristics and parity matter?

Although the economic independence of women has been greatly advanced in recent decades, it continues to lag far behind men’s in the Netherlands and elsewhere. The negative consequences of motherhood are an important driving force behind women’s abiding lower income. Although mother’s lower earnings have received a substantial amount of attention from scholars and the underlying mechanisms are well established, surprisingly little is known about mitigating factors. This article contributes to the literature by investigating how the earnings disadvantage of mothers is affected by partner characteristics and by parity. We formulate hypotheses about the effect of a partner’s working hours, his earnings and his gender role orientations, on the earnings disadvantage associated with motherhood. Furthermore, we examine the role of parity in this earnings disadvantage. Our hypotheses are tested using longitudinal data from the first three waves of the Netherlands Kinship Panel Study. Our hypotheses concerning partner characteristics are not supported. The earnings disadvantage of mothers is hardly affected by them. We do find that parity matters greatly in examining the effect that motherhood has on women’s earnings. The transition to motherhood has a much larger effect on earnings than the birth of subsequent children. The implications of these findings and the specificity of the Dutch context are discussed.     

Bayesian estimation of extropy and goodness of fit tests

Extropy, a complementary dual of entropy, is considered in this paper. A Bayesian approach based on the Dirichlet process is proposed for the estimation of extropy. A goodness of fit test is also developed. Many theoretical properties of the procedure are derived. Several examples are discussed to illustrate the approach.
