Impact of maternal adverse childhood experiences on child socioemotional function in rural Kenya: Mediating role of maternal mental health

Mothers in low‐ and middle‐income countries (LMIC) suffer heightened vulnerability for adverse childhood experiences (ACEs), which is exacerbated by the multitude of risk factors associated with poverty and may lead to increased risk of psychiatric disorder. The constellation of complex, co‐occurring biological, environmental, social, economic and psychological risk factors are in turn transmitted to her child, conferring vulnerability for adverse development. This study examines the association between maternal intra‐ and extra‐familial ACEs, maternal education and the mental health of her child, mediated by maternal mental health. Mother‐child dyads (n = 121) in Machakos, Kenya were examined cross‐sectionally using self‐report measures of ACEs, maternal mental health and child internalizing and externalizing mental health problems. The four models proposed to examine the relationship between intra‐ and extra‐familial maternal ACEs and child internalizing and externalizing problems demonstrated indirect pathways through maternal mental health. These effects were found to be conditional on levels of maternal education, which served as a protective factor at lower levels of maternal ACEs. These models demonstrate how the impact of ACEs persists across the lifespan resulting in a negative impact on maternal mental health and conferring further risk to subsequent generations. Elucidating the association between ACEs and subsequent intergenerational sequelae, especially in LMIC where risk is heightened, may improve targeted caregiver mental health programs for prevention and intervention.     

Generating and sharing of market intelligence in sales teams: an economic social network perspective

In this research, we take a multimethod approach to shed light on the potential costs to sales teams that generate and share market intelligence (MI). First, we introduce an analytical model to propose the respective levels of effort that sales managers, experts, and team members spend generating and sharing MI. To test our propositions, we utilize social network data from 40 independent, business-to-business (B2B) sales teams, representing 287 salespeople. Interestingly, our results support the premise that team members become dependent (reduce MI efforts) when their sales manager or team expert shares MI among the team. We term this a “sharing tax” that sales managers and team experts pay when they share MI. Consequently, sales managers demonstrate greater MI-generation efforts the more they share MI. We also find that experts who share more (less) also show greater (lesser) MI-generation efforts, but only for teams where sales managers share low (high) levels of MI. In summary, our research innovatively conducts an empirical test of the Nash Equilibrium pattern of sales team effort to show that two critical team members, the sales manager and expert, are at a disadvantage when they share valuable MI.     

Do Construal Levels Affect Athletes’ Imagery and Performance Outcomes? It Depends on the Task!

We investigated the hypothesis that an interaction of construal levels and task types would improve performance outcomes, mediated by imagery abstraction levels. In a pilot study (N = 30; table tennis rallies, jumps, throws) and a main study (N = 32; badminton rallies, soccer penalties), athletes performed tasks after receiving high or low construal frames, with an imagery recall completed in the main study. Table tennis and badminton players won more rallies in low construal conditions; track athletes and soccer penalties had higher success rates in high construal conditions. Frames impacted self-reported imagery, but abstraction levels of imagery did not affect outcomes.     

Perceptions of the Social Psychological Climate and Sport Commitment in Adolescent Athletes: A Multilevel Analysis

The present study investigated the relationship between the social psychological climate and sport commitment on both the individual and team level. High school athletes (n = 400) competing on 27 different teams completed motivational climate, caring climate, and sport commitment measures. Multilevel models were constructed to examine the hierarchical relationship between the climates and commitment. Task-involving (γ₂₀ =.15, t = 2.31, p =.02) and caring climates (γ₁₀ =.33, t = 3.48, p =.002) were significantly related to commitment on the individual level, and a task-involving climate (γ₀₂ = 1.13, t = 2.90, p =.008) was significantly related to commitment on the team level. In an effort to enhance commitment, coaches and sport psychology consultants may wish to employ strategies targeted toward the facilitation of task-involving and caring climates.     

The effects of social desirability bias on applied measures of goal orientation

This research examined the extent to which social desirability responding influences two measures of goal orientation tailored to work (VandeWalle, 1997) and academic (Midgley et al., 1998) domains. Method bias analyses indicated a significant negative influence of social desirability on responses to learning goal items, and a significant positive influence of social desirability responding on performance-avoid goal items, with the VandeWalle scale showing larger effects than the Midgley et al. scale. Performance-approach goal items showed minimal effects of social desirability responding. Results are discussed with respect to the use of these measures in larger models of motivation and performance.     

Self-Presentation in Exercise Contexts: Differences Between High and Low Frequency Exercisers

The present study investigated the relationship between cognitive manifestations of self-presentation (social physique anxiety, self-presentational efficacy, impression motivation, and exercise imagery) and exercise behavior in 235 female exercisers. Each participant completed the Social Physique Anxiety Scale, a measure of self-presentational efficacy, the impression motivation subscale of the Self-Presentation in Exercise Questionnaire, and the Exercise Imagery Questionnaire. The results of a MANCOVA indicated high-frequency exercisers reported higher levels of efficacy expectancy, outcome value, and exercise imagery than did low-frequency exercisers. Semi-partial correlations showed efficacy expectancy, outcome expectancy, and appearance imagery each accounted for significant variance in social physique anxiety, independent of other predictors. Self-presentational efficacy expectancy appears to be a potent variable in both exercise behavior and social physique anxiety.     

Alcohol-related amnesia and dementia: animal models have revealed the contributions of different etiological factors on neuropathology, neurochemical dysfunction and cognitive impairment

Chronic alcoholism is associated with impaired cognitive functioning. Over 75% of autopsied chronic alcoholics have significant brain damage and over 50% of detoxified alcoholics display some degree of learning and memory impairment. However, the relative contributions of different etiological factors to the development of alcohol-related neuropathology and cognitive impairment are questioned. One reason for this quandary is that both alcohol toxicity and thiamine deficiency result in brain damage and cognitive problems. Two alcohol-related neurological disorders, alcohol-associated dementia and Wernicke-Korsakoff syndrome have been modeled in rodents. These pre-clinical models have elucidated the relative contributions of ethanol toxicity and thiamine deficiency to the development of dementia and amnesia. What is observed in these models--from repeated and chronic ethanol exposure to thiamine deficiency--is a progression of both neural and cognitive dysregulation. Repeated binge exposure to ethanol leads to changes in neural plasticity by reducing GABAergic inhibition and facilitating glutamatergic excitation, long-term chronic ethanol exposure results in hippocampal and cortical cell loss as well as reduced hippocampal neurotrophin protein content critical for neural survival, and thiamine deficiency results in gross pathological lesions in the diencephalon, reduced neurotrophic protein levels, and neurotransmitters levels in the hippocampus and cortex. Behaviorally, after recovery from repeated or chronic ethanol exposure there is impairment in working or episodic memory that can recover with prolonged abstinence. In contrast, after thiamine deficiency there is severe and persistent spatial memory impairments and increased perseverative behavior. The interaction between ethanol and thiamine deficiency does not produce more behavioral or neural pathology, with the exception of reduction of white matter, than long-term thiamine deficiency alone.     

The psychological well-being of employees who handle cash in a bank in inner city Johannesburg

The aim of the study was to compare the psychological well-being of bank employees who handled cash and those who did not. The study assessed employees' levels of work stress, burnout and life satisfaction. The Job Stress Survey Scale was used to measure work stress, Maslach Burnout Inventory was used to measure burnout and the Congruity Life Satisfaction Scale was used to measure life satisfaction. Two independent sample t tests were run on Statistical Analysis Software. The results showed that the two groups differed significantly in terms of work stress, emotional exhaustion, depersonalisation and overall burnout. The findings of this study suggest the need for organisational support, skills development and the provision of wellness programmes for bank employees.
