The transition from deployment to reintegration can be stressful for returning military personnel and at-home partners, and support plays a key role in their ability to transition effectively. We draw on relational turbulence theory to advance predictions about how parameters of the relationship between returning service members and at-home partners predict their perceptions of their partner’s support during the post-deployment transition. We surveyed 235 individuals (117 returning service members, 118 at-home partners) who had experienced the transition within the past 6 months. Findings consistent with the theory indicated that relational turbulence partially mediated the negative associations that relational uncertainty and interference from a partner shared with partner support. Partner uncertainty was a direct negative predictor of partner support as well. We consider how these results extend theory, research, and practice.  相似文献

Given that physical activity (PA) tends to decrease with age during adolescence, addressing factors that affect change is important. This study examined the similarity and interdependence of PA as influenced by psychosocial factors among adolescent best friend dyads. A total of 660 adolescents, representing 330 best friend dyads, completed questionnaires with regard to PA, sitting time, perceived exercise benefits and barriers, physical self-perception and social support for PA. Dyads were also identified as reciprocal and non-reciprocal best friends; reciprocal means that both considered each other best friends and non-reciprocal were those in which only one considered the other a best friend. Data were analysed using a hierarchical linear model framework. Results indicated significant similarities between reciprocal best friend dyads for PA and sitting time, and for sitting time in non-reciprocal best friends (P values <.01). Psychosocial variables were associated with PA in reciprocal best friend dyads and with sitting time in reciprocal and non-reciprocal best friend dyads. Best friend gender, regular sports practice of the person, perceived exercise barriers of the best friend and best friend social support were the best predictors for PA.  相似文献

在企业技术战略转型的过程中,研发资源的投入不断增加,因此如何有效地配置研发资源也成为重要的议题。从"战略-结构-绩效"范式的角度出发,以三一重工为例进行个案研究,对企业技术战略与研发资源配置结构、创新绩效的关系进行研究,结果表明研发资源配置结构会随着技术战略的变化而调整,并影响创新绩效。研究结果发展了"战略-结构-绩效"范式在技术管理领域的理论研究,为技术战略升级的资源优化配置提供理论依据。  相似文献

我国制造业产业间技术外溢的实证研究   总被引:1,自引:1,他引:1  
蔡虹  陆震宇 《科学学研究》2006,24(Z2):408-413
在分析技术外溢双方互动机制的基础上,测算出我国制造业10个产业的技术知识存量在1990~2002年的发展水平和趋势,并对各产业的技术同化能力系数和吸收的外溢技术知识存量进行实证研究,结果表明,同化外溢技术已经成为产业技术知识存量增加的重要来源。  相似文献

从企业生命周期角度出发,实证研究我国政府补助对生命周期不同阶段的企业研发投入的影响。研究结果表明,我国对初创期的企业政府补助力度不足,对成熟期和衰退期企业补助过多。政府补助与初创期企业研发投入强度呈线性正相关关系,与成长期企业RD投入强度存在"倒U型"曲线关系,对于成熟期的企业来说,没有证据表明政府补助强度的升高会对成熟期企业研发投入有促进或者抑制作用。政府补助对衰退期企业的研发活动有一定的激励效果。因此,建议政府应当继续增加RD投入,加大基础研究和应用研究力度,引入市场竞争和淘汰机制,倒逼国有企业加大研发力度,根据不同生命周期的企业的不同经营特点,有针对性和导向性地对企业进行补助。  相似文献

BackgroundChildren who experience Child Abuse and Neglect (CAN) are at an increased risk of becoming a victim of Intimate Partner Violence (IPV) or a perpetrator of IPV or CAN. Moreover, maltreated children are at risk for developing long-lasting trauma symptoms, which can subsequently affect their own children’s lives. Understanding the mechanisms of the intergenerational transmission of violence and trauma is a prerequisite for the development of interventions.ObjectiveWe examine whether the relation between historical CAN and current trauma symptoms of mothers is mediated by current IPV. Furthermore, we investigate whether current CAN mediates the relation between current maternal trauma symptoms and child Post-Traumatic Stress Disorder (PTSD) symptoms. These mechanisms are compared for mothers and fathers.ParticipantsWe have recruited 101 fathers and 360 mothers (426 children, 50% boys, mean age 7 years) through child protection services.MethodsRespondents completed questionnaires about IPV, (historical) CAN and trauma symptoms.ResultsStructural equation models revealed that historical CAN of father and mothers was related to trauma symptoms. Only for mothers, this association was mediated by IPV. Trauma symptoms of both fathers and mothers were related to child PTSD symptoms. This effect was not mediated by current CAN.ConclusionIn violent families, maternal and paternal trauma can be transmitted over generations. However, intergenerational transmission of violence is found for mothers only. When family violence is reported, professionals should take the violence into account, as well as the history of parents and trauma symptoms of all family members.  相似文献

以2007至2017年沪深A股上市公司为研究对象,本文考察了开发支出资本化对企业创新的影响。,实证结果研究发现,开发支出资本化比例与企业创新呈倒U型关系。且结论在稳健性检验之后依然成立。表明:当开发支出资本化比例低于临界值时,由于抑制了管理层通过削减研发投资以实现盈余目标的动机得到抑制,从而促进企业创新;当开发支出资本化比例高于临界值时,促使管理层基于声誉风险管理层为避免将已资本化金额转为费用对当期盈余造成的负面冲击,进行过度研发投资,从而阻碍企业创新。说明不同开发支出资本化比例下,管理层研发投资不同动机对企业创新产生非线性影响。结论在稳健性检验之后依然成立。进一步分析还发现:,开发支出资本化通过研发投资效率作用于企业创新,而且管理层面临的盈余公告压力越大,开发支出资本化对企业创新的非线性影响更为显著。资本化通过非效率研发投资,作用于企业创新;盈余公告压力越大,资本化与企业创新之间的倒U型关系越明显。  相似文献
