This study used three-level generalized hierarchical linear modeling to examine trajectories of husbands’ and wives’ physical and emotional aggression over three assessments and the effects of years since marriage. In this community sample of 118 couples, physical aggression significantly decreased over time (43% per year). Emotional aggression did not significantly change over time, but trajectories significantly differed for husbands (3% increase) versus wives (10% decrease). Longer-duration marriages had lower physical aggression and, for wives only, lower emotional aggression. Aggression trajectories showed considerable variability: 44%–55% of physically aggressive spouses desisted from one assessment to the next; 5%–12% reported start-ups in physical aggression. Discussion addresses the role of gender and type of aggression in aggression trajectories.

Background: Although several studies have clearly shown that depressive symptoms in stroke survivors and caregivers decreases their quality of life (QOL), previous research has not yet analyzed the role of potential moderators in the relationship between the above two variables. Aims: To examine the moderating effect of caregiver preparedness between depressive symptoms and QOL in stroke survivor and caregiver dyads. Methods: Longitudinal design with 222 stroke survivor-caregiver dyads enrolled at survivor discharge from rehabilitation hospitals. Data collection was performed over 12 months. We measured survivor and caregiver QOL dimensions (physical, psychological, social and environmental), depression and preparedness. Hierarchical Linear Modeling was used to test four longitudinal dyadic moderation models (one for each QOL domain). Results: Survivors (50% males) and caregivers (65% females) were 70.8 (SD=11.9) and 52.5 (SD=13.1) years old, respectively. Controlling for baseline covariates, caregiver preparedness significantly moderated the association between survivor depressive symptoms and survivor psychological (B = 0.56, p < .01) and environmental (B = 0.58, p < .01) QOL at baseline and social QOL over time (B = 0.24, p < .05). In each case, higher levels of caregiver preparedness were protective and buffered the influence of survivor depressive symptoms on survivor QOL. Similarly, caregiver preparedness significantly moderated the association between caregiver depressive symptoms and caregiver physical (B = 0.25, p < .01) and environmental (B = 0.18, p < .05) QOL over time. Conclusions: Caregiver preparedness is a positive variable for both members of the dyad and the paper highlights the importance of implementing tailored intervention which could improve caregivers’ preparedness already during the rehabilitation period.

Background and Purpose: Depression and quality of life (QOL) have an interdependent and transactional nature in stroke survivor-caregiver dyads. While the strong relationship between depression and physical and emotional QOL in stroke survivor-caregiver dyads is well known, it is less clear if this relationship is moderated by caregiver preparedness, which could easily be targeted with interventions. In this study, we examined the moderating role of caregiver preparedness on the association between depression and QOL in stroke survivor-caregiver dyads. Methods: We used a longitudinal design with follow-ups every 3 months over a 1-year period. Considering the nonindependent nature of the data (survivors and their caregivers), we used multilevel modeling to analyze data at the dyad level. We implemented 4 longitudinal dyadic moderation models (one for each QOL domain: physical, psychological, social, and environmental) using hierarchical linear modeling. Results: A sample of 222 stroke survivor-caregiver dyads was analyzed. Stroke survivors were older ( M =70.8, SD=11.9) than their caregivers ( M =52.4, SD=13.1). Stroke survivors predominantly had an ischemic stroke, equally distributed by site. Caregivers were primarily female (66%), with a medium to high educational level (57%). Caregiver preparedness significantly moderated the association between survivor depression and survivor psychological ( B =0.56, P <0.01) and environmental ( B =0.58, P <0.01) QOL at baseline and social QOL over time ( B =0.24, P <0.05). Similarly, caregiver preparedness significantly moderated the association between caregiver depression and caregiver physical ( B =0.25, P <0.01) and environmental ( B =0.18, P <0.05) QOL over time. Conclusions: Caregiver preparedness has a positive influence on both members of the dyad. Assessment of stroke-caregiver preparedness could be helpful to motivate clinicians to develop and implement interventions for stroke survivor-caregiver dyads.

Abstract This study examined ways in which rhythmic features of movement contribute to bonding between individuals. Though previous studies have described synchrony as a form of social glue, this research extends those findings to consider the impact of fast versus slow tempo on movement synchrony. This two-part experiment examined dyadic interactions as they occurred between same-sex strangers (Study 1) and friends (Study 2). Participants were video-recorded as they engaged in 5- or 6-min chats, and synchrony was evaluated using wavelet transform via calculations of cross-wavelet coherence. Study 1 employed regression commonality analysis and hierarchical linear modeling and found that among various frequency bands, rapport between individuals was positively associated with synchrony under 0.025 Hz (i.e., slower than once every 40 s) and 0.5–1.5 Hz (i.e., once every 0.67–2 s). On the contrary, Study 2 determined that synchrony of 0.5–1.5 Hz was not impactful among friend dyads and only predictive of the motivation to cultivate a friendly relationship during interactions with strangers. These results indicate the existence of a distinctive rhythm for bonding individuals, and the role of pre-existing friendship as a moderator of the bonding effect of synchrony. However, the role of relative phase (i.e., timing of movement; same versus opposite timing) remains unclear, as the ratio of in- and anti-phase patterning had no significant influence on perceived rapport and motivation to develop relationships. On the basis of the research results, a theoretical contribution is proposed to the study of interpersonal coordination.

Abstract. Core self-evaluations (CSEs) represent a prominent construct with links to a number of important organizational behaviors and outcomes. Previous research on this variable appears to have assumed that CSE is a stable trait. However, very little research has examined this assumption, particularly over longer time periods. This study investigated this issue, focusing on within-person variability in CSE. Drawing from several theoretical perspectives related to self-concept, we examined the extent to which levels of this construct varied over several years as well as potential predictors of this variability. Hierarchical linear modeling analyses indicated there was substantial within-person variance in CSE over time and this variability was related to income and education. These findings shed additional light on the fundamental nature of CSE, contributing to a new perspective on this construct with potential implications for employees, organizations, and researchers.

Dynamic Criteria

The selection literature has long debated the theoretical and practical significance of dynamic criteria. Recent research has begun to explore the nature of individual performance over time. This study contributes to this body of research through a hierarchical linear modeling analysis of dynamic criteria. The purpose of this study was to investigate the role of ability in explaining initial job performance, as well as the rate of improvement-or performance trend-among a sample of 408 sewing machine operators over a 24 week period. The results of a hierarchical linear modeling analysis suggest that ability measures are differentially related to initial performance and performance improvement trend.

Positive Effect

Purpose Earlier research confirms the positive effect of innovation in shaping growth ambitions of entrepreneurs. The aim of this paper is to investigate whether the effect of innovation on growth ambitions of entrepreneurs is contingent on the role of institutions, namely, culture and economic freedom. In other words, the authors’ objective is to provide an institutionally contingent understanding of the role of innovation in shaping growth ambitions of early-stage entrepreneurs. Design/methodology/approach The authors applied hierarchical linear modeling technique on the data of 100,566 early-stage entrepreneurs in 109 countries that participated in annual surveys of Global Entrepreneurship Monitor. Findings The authors find that the effect of innovation on shaping growth ambitions of early stage entrepreneurs is contingent on the role of culture such that, in secular cultures, innovation benefits growth ambitions more than traditional cultures. Further, the authors found that the effect of innovation on growth expectations is dependent on the level of economic freedom in the country in which the firms operate so that in the countries with higher level of economic freedom, early-stage entrepreneurs expect more growth out of their innovation as compared to their counterparts in the depressed economies. Originality/value The results contribute to our understanding of entrepreneurial growth aspirations as a result of the interplay of entrepreneur–firm–environment nexus.

This chapter deals with the role of the self and conscience in defending oneself against the charge of witchcraft. To add depth to intellectual concepts—and teleologies—of the self, we must understand how the individual self was understood, felt, and experienced. Particularly for the crime of witchcraft, the crux of the trial was premised on the moral question of what kind of person would commit such a crime. Those on trial for witchcraft in the Lutheran duchy of Württemberg invoked the idioms of ‘mind’, ‘conscience’, ‘heart’, or ‘self’ in constructing their defence. Through four case studies, ranging from 1565 to 1678, this chapter examines the different ways in which people could conceptualize their person, and shows that change over time in the ‘development’ of the modern self was not a uniform or directly linear pattern.

Background. Upper limb (UL) performance, or use, in daily life is complex and likely influenced by many factors. While the recovery trajectory of UL impairment poststroke is well documented, little is known about the recovery trajectory of sensor-measured UL performance in daily life early after stroke and the potential moderating role of psychosocial factors. Objective. To examine the recovery trajectory of UL performance within the first 12 weeks poststroke and characterize the potential moderating role of belief, confidence, and motivation on UL performance. Methods. This was a longitudinal, prospective cohort study quantifying UL performance and related psychosocial factors early after stroke. UL performance was quantified via bilateral, wrist-worn accelerometers over 5 assessment sessions for 24 hours. Belief, confidence, and motivation to use the paretic UL, and self-perceived barriers to UL recovery were quantified via survey. Change in 4 accelerometer variables and the moderating role of psychosocial factors was tested using hierarchical linear modeling. The relationship between self-perceived barriers and UL performance was tested via Spearman rank-order correlation analysis. Results. UL performance improved over the first 12 weeks after stroke. Belief, confidence, and motivation did not moderate UL performance over time. There was a negative relationship between UL performance and self-perceived barriers to UL recovery at week 2, which declined over time. Conclusions. Sensor-measured UL performance can improve early after stroke. Early after stroke, rehabilitation interventions may not need to directly target belief, confidence, and motivation but may instead focus on reducing self-perceived barriers to UL recovery.
