IntroductionThe dynamics pertaining to work-family interface such as conflict, enrichment, etc. have received considerable scholarly attention in social sciences. However, the daily processes that are involved have been examined to a lesser extent, least of all including the role played by emotions.ObjectiveThis study aimed at examining, consistently with the Affective Events Theory, if positive and negative affect experienced during the working day played a mediational role in the associations between daily levels of work-family conflict and work-family enrichment on one side, and work-family balance on the other. Moreover, the moderating cross-level role of trait emotional stability was examined.MethodThe study included a convenience sample of 104 Italian employees who completed a diary-book over five consecutive working days.ResultsMultilevel-modelling results highlighted, controlling for emotional stability, a mediational role of only daily positive affect in the relationships between both work-family conflict and enrichment on the one side and work-family balance on the other side.ConclusionThis study contributed to the literature emphasizing the role of positive affective states experienced at the workplace and their connections with the private life. Limitations and implications for research and practice are described.  相似文献

A number of studies point to methadone exposure in utero as a possible risk factor in the developing mother–infant relationship in the first year of life. This study is part of a larger, national follow-up of 38 infants prenatally exposed to methadone or buprenorphine and 36 comparison, low-risk infants. The aim of the present paper is to assess the quality of mother–infant relationship when the infants are 6 months old. Videotaped mother–infant interactions were rated in a global scale (NICHD). Maternal and infant contributions collapsed into the variables “infant style” and “maternal style” showed that the only factor making significant contribution to the outcome measure “dyadic mutuality” was maternal style. The importance of group membership (exposed versus non-exposed), was reduced when controlling for maternal drug use prior to opioid maintenance treatment (OMT), maternal depression and parenting stress as well as infants’ developmental status and sensory-integrative functions. This suggests that prediction of dyadic mutuality should be based on individual characteristics rather than group characteristics. These results support previous research findings that methadone and buprenorphine use per se does not have direct influence on the quality of early mother–infant relationship, but tailored follow-up procedures targeting drug-free pregnancies and parenting support are beneficial for women in OMT and their children.  相似文献

Jurors' decision-making processes are often influenced by extra-legal factors, including judgments of defendants and plaintiffs. Two studies comparing the decisions of university students with those of community jurors sought to determine if extra-legal factors such as individual differences (including identity as a student or juror participant), the reason for surgery (medically necessary vs. elective), the type of surgery (e.g., gastric bypass, nasal reconstruction) or weight of the patient influenced jurors' decisions and perceptions in medical malpractice suits, such that participants would hold negative perceptions of overweight patients or patients who undergo elective surgeries. Results indicate that students and jurors differ in perceptions of the patient's injury and perceptions of risk, which explains some of the variance in liability verdicts. Students were more likely to find doctors liable, but also were more likely to assign responsibility to patients than were jurors. Patients who had undergone elective surgery were seen as more responsible for their situation - and their doctors were assigned less responsibility - than those who had undergone a medically necessary surgery. Tests of weight bias showed that jurors found overweight patients less responsible for their situation than patients of normal weight, but students showed the opposite pattern. Theoretical explanations are explored and implications discussed.  相似文献

The potential effect of gender on intellectual abilities remains controversial. The purpose of this research was to analyze gender differences in cognitive test performance among children from continuous age groups. For this purpose, the normative data from 7 domains of the newly developed neuropsychological test battery, the Evaluación Neuropsicológica Infantil [Child Neuropsychological Assessment] (Matute, Rosselli, Ardila, & Ostrosky-Solis, 2007), were analyzed. The sample included 788 monolingual children (350 boys, 438 girls) ages 5 to 16 years from Mexico and Colombia. Gender differences were observed in oral language (language expression and language comprehension), spatial abilities (recognition of pictures seen from different angles), and visual (Object Integration Test) and tactile perceptual tasks, with boys outperforming girls in most cases, except for the tactile tasks. Gender accounted for only a very small percentage of the variance (1%-3%). Gender x Age interactions were observed for the tactile tasks only. It was concluded that gender differences during cognitive development are minimal, appear in only a small number of tests, and account for only a low percentage of the score variance.  相似文献

The authors reviewed article and author patterns for articles published in the Journal of Employment Counseling (JEC) from 1994 through 2009. Author demographic characteristics assessed included sex of lead and all authors, lead author domicile, employment setting of lead and all authors, and individuals and universities contributing most frequently to JEC. Article content was identified and research articles published in JEC were specifically analyzed for trends over time during 4‐year periods, including type of research design, quantitative/qualitative approach, intervention/nonintervention focus, random versus nonrandom sampling/assignment, sample size, participant types, and statistical analyses used.  相似文献

[Correction Notice: An Erratum for this article was reported in Vol 48(5) of Developmental Psychology (see record 2012-09244-001). Figure 2 was distorted in production. The correct version is presented in the erratum.] Adolescence is a period of radical normative changes and increased risk for substance use, mood disorders, and physical injury. Researchers have proposed that increases in reward sensitivity (i.e., sensitivity of the behavioral approach system [BAS]) and/or increases in reactivity to all emotional stimuli (i.e., reward and threat sensitivities) lead to these phenomena. The present study is the first longitudinal investigation of changes in reward (i.e., BAS) sensitivity in 9- to 23-year-olds across a 2-year follow-up. Support was found for increased reward sensitivity from early to late adolescence, and evidence was found for decline in the early 20s. This decline is combined with a decrease in left nucleus accumbens (Nacc) volume, a key structure for reward processing, from the late teens into the early 20s. Furthermore, we found longitudinal increases in sensitivity to reward to be predicted by individual differences in the Nacc and medial orbitofrontal cortex (OFC) volumes at baseline in this developmental sample. Similarly, increases in sensitivity to threat (i.e., behavioral inhibition system sensitivity) were qualified by sex, with only females participants experiencing this increase, and predicted by individual differences in lateral OFC volumes at baseline.

This study investigates the relation of young adult identities (ages 18-22 years), reflecting subjective age and psychosocial maturity, to educational and career attainment in young adulthood (ages 25-29 years). Add Health data show that having an older subjective age alone does not curtail attainment; the critical issue is the level of psychosocial maturity that accompanies subjective age. Those with older subjective ages and low psychosocial maturation have the lowest attainment at ages 25-29 years, while those with older subjective ages and high psychosocial maturation show considerable progress toward work-related attainment. For those with younger subjective ages, a lower level of psychosocial maturity is not as detrimental to attainment. (PsycINFO Database Record (c) 2012 APA, all rights reserved).  相似文献

With the conventional wars being rarer, low intensity conflict (LIC) operations have now become a norm. This new military environment is characterized by ambiguous and unpredictable situations, complex goals, invisible enemy combatants, political sensitivities, undefined restraints on weaponry tactics and associated multiple microstressors that make it highly stressful and cognitively demanding for soldiers. Considering LIC stress under a holistic / interactionistic paradigm, this review paper examines (i) the unique stressors of LIC operations and their impact on soldiers?? mental health and fitness, cognitive functioning, combat readiness and effective performance; (ii) preventive training programmes (Hardiness Training and Comprehensive Soldier Fitness) for developing and sustaining resilience; (iii) the central role of military leadership and structure as key components of combat stress control, unit cohesion, institutional support and other HR practices (e.g., command consultation, grievance redresssal, performance appraisal, communication, conflict resolution); and (iv) mental health services as coping resources and potential stress countermeasures such as psychological first aid, after-action debriefing, operational stress training, suicide prevention, treatment of stress casualities, help-seeking skills and self-care as part of preventive mental health training and post-trauma rehabilitation. The roles of both the skill-building and the stress-combating aspects of training, leadership, organizational support / HR practices and mental health services seem important as potential moderators of stress-strain relationship in LIC operations.  相似文献

Classic cognitive theory conceptualizes executive functions as involving multiple specific domains, including initiation, inhibition, working memory, flexibility, planning, and vigilance. Lesion and neuroimaging experiments over the past two decades have suggested that both common and unique processes contribute to executive functions during higher cognition. It has been suggested that a superordinate fronto–cingulo–parietal network supporting cognitive control may also underlie a range of distinct executive functions. To test this hypothesis in the largest sample to date, we used quantitative meta-analytic methods to analyze 193 functional neuroimaging studies of 2,832 healthy individuals, ages 18–60, in which performance on executive function measures was contrasted with an active control condition. A common pattern of activation was observed in the prefrontal, dorsal anterior cingulate, and parietal cortices across executive function domains, supporting the idea that executive functions are supported by a superordinate cognitive control network. However, domain-specific analyses showed some variation in the recruitment of anterior prefrontal cortex, anterior and midcingulate regions, and unique subcortical regions such as the basal ganglia and cerebellum. These results are consistent with the existence of a superordinate cognitive control network in the brain, involving dorsolateral prefrontal, anterior cingulate, and parietal cortices, that supports a broad range of executive functions.  相似文献
