Visualizing the landscape and evolution of leadership research

Complementing prior quantitative and qualitative reviews of the leadership literature, we conduct a bibliometric analysis of leadership articles. Our bibliometric review provides a different perspective by portraying the landscape and developmental trajectory of leadership research over time via co-citation and co-occurrence analyses. Using a scientific visualization tool CiteSpace and 6528 leadership works collected from the Web of Science database from 1990 to 2017, we detect and visualize the landscape of leadership research and track how this landscape has evolved. After mapping the landscape, we discuss the insights gleaned from our bibliometric review, with a focus on open questions, future research directions, and implications. In doing so, our review provides readers with a systematic understanding of the development of the leadership field and a roadmap to spark leadership research and move this literature forward.     

Fertility and Infertility: Toward an Integrative Research Agenda

In this article, we show that social science research on fertility and infertility consists of largely separate research traditions, despite shared interest in pregnancies and births (or lack thereof). We describe four ways these two traditions differ: (1) publication trajectories and outlets, (2) fields of study and major theoretical frameworks, (3) degree of attention to the other topic, and (4) language and definitions used. We then discuss why future integration of these bodies of research would be beneficial, outline potential steps toward rapprochement, and provide common areas of dialogue that could facilitate and enrich these bodies of research. We offer a more holistic framework using the reproductive career as an extension of existing lifecourse approaches in both fertility and infertility research. We conclude with a brief empirical example and discussion of methodological issues for measuring and modeling reproductive careers.     

Retracted: The Development of Willingness to Sacrifice and Unmitigated Communion in Intimate Partnerships

The above article, published online on December 27, 2017 in Wiley Online Library ( wileyonlinelibrary.com ) has been retracted by agreement between the author, journal Editor in Chief Kristi Williams and Wiley Periodicals, Inc. The retraction has been agreed due to discovery of a coding error by the author. The labeling for the willingness to sacrifice and unmitigated communion items was mistakenly reversed during the construction of the longitudinal dataset. The authors notified the editor immediately upon discovering the error. Although the central conclusions of the research are unchanged, a fully corrected version of the paper is forthcoming.     

Experimenter Presence or Absence: An Experimental Analogue with Implications for Organizational Behavior Management

Students performed a simulated bank-proofing task individually in a lab with either the experimenter present or absent. Although run rates were similar, those in the Experimenter-Absent Group were off-task twice as much during sessions. Error frequencies for both groups were low and similar while rates of responding were significantly higher (+13%) in the Experimenter-Present Group because participants were off-task less often. Most human lab experiments fail to specify whether experimenters are present or absent in the room and this extraneous variable is a potential confound that should be controlled in future studies.     

Victimization,Aggression, and Other Problem Behaviors: Trajectories of Change Within and Across Middle School Grades

This study examined trajectories of victimization and problem behaviors within and across three grades of middle school. Participants were 2,166 adolescents from three urban middle schools in the United States who completed measures of victimization, physical and relational aggression, substance use, and delinquent behavior. Latent curve analyses modeled changes in each construct across 12 waves collected every 3 months. In each case, the best‐fitting model required separate linear slopes to represent changes within each grade and a factor representing decreases in the summers. Positive cross‐construct correlations were found for intercepts, linear slopes, and measures within waves. The findings suggest strong associations among victimization and problem behaviors, and individual differences in their patterns of change both within and across grades.     

Is “Sexual Competence” at First Heterosexual Intercourse Associated With Subsequent Sexual Health Status?

The timing of first sexual intercourse is often defined in terms of chronological age, with particular focus on “early” first sex. Arguments can be made for a more nuanced concept of readiness and appropriateness of timing of first intercourse. Using data from the third National Survey of Sexual Attitudes and Lifestyles (Natsal-3), conducted in 2010–2012, this study examined whether a context-based measure of first intercourse—termed sexual competence—was associated with subsequent sexual health in a population-based sample of 17-to 24-year-olds residing in Britain (n = 2,784). Participants were classified as “sexually competent” at first intercourse if they reported the following four criteria: contraceptive protection, autonomy of decision (not due to external influences), that both partners were “equally willing,” and that it happened at the “right time.” A lack of sexual competence at first intercourse was independently associated with testing positive for human papillomavirus (HPV) at interview; low sexual function in the past year; and among women only, reported sexually transmitted infection (STI) diagnosis ever; unplanned pregnancy in the past year; and having ever experienced nonvolitional sex. These findings provide empirical support for defining the nature of first intercourse with reference to contextual aspects of the experience, as opposed to a sole focus on chronological age at occurrence.     

Social Network Typologies of Black and White Married Couples in Midlife

Although research shows that conjoint social networks are associated with well‐being among newlyweds, little is known about how these network types are linked to marital quality and psychological well‐being for long‐term married couples and about potential race differences in their configurations and associations. Using a pattern‐centered approach to examine the social networks of 91 White and 62 Black couples in their 16th year of marriage, this study revealed four couple network types (friend‐focused, wife family‐focused, bilateral family‐focused, and diverse). Results suggested that spouses in the wife family‐focused network type (characterized by above‐average contact with the wife's family and below average contact with the husband's family and with nonkin) reported the lowest positive marital quality and highest negative marital quality. The association of network type with negative marital quality was also moderated by gender and race. The findings highlight the importance of considering the meaningful complexity within couples' shared networks.     

Nonparametric Two‐Sample Tests of the Marginal Mark Distribution with Censored Marks

Occasionally, investigators collect auxiliary marks at the time of failure in a clinical study. Because the failure event may be censored at the end of the follow‐up period, these marked endpoints are subject to induced censoring. We propose two new families of two‐sample tests for the null hypothesis of no difference in mark‐scale distribution that allows for arbitrary associations between mark and time. One family of proposed tests is a nonparametric extension of an existing semi‐parametric linear test of the same null hypothesis while a second family of tests is based on novel marked rank processes. Simulation studies indicate that the proposed tests have the desired size and possess adequate statistical power to reject the null hypothesis under a simple change of location in the marginal mark distribution. When the marginal mark distribution has heavy tails, the proposed rank‐based tests can be nearly twice as powerful as linear tests.
