Work–family conflict,relational turbulence mechanisms,conflict tactics and marital satisfaction*     

Timothy R. Worley  Marina R. Shelton 《Journal of Applied Communication Research》2020,48(2):248-269

ABSTRACT

This study examined how work–family conflict (WFC) is associated with mechanisms of relational turbulence, conflict tactics, and marital satisfaction. Six hundred and thirty-three married workers completed an online survey. Family interference with work and spouses’ work interfering with one’s family predicted greater relational uncertainty and interference from partners, whereas one’s own work interfering with family did not predict these mechanisms of turbulence. All three sources of relational uncertainty, and interference from partners, predicted increased avoidance and distributive tactic use. Facilitation from partners predicted increased use of integrative tactics. Finally, relational uncertainty, interference from partners, and distributive conflict tactics partially mediated the associations of WFC with marital satisfaction.  相似文献   

Relational maintenance and caregiving in the grandparent-grandchild relationship     

Daniel H. Mansson 《Communication Research Reports》2020,37(1-2):1-10

ABSTRACT

The purpose of this study was to examine the relationships between grandparents’ use of relational maintenance behaviors (RMB) and their young adult grandchildren’s willingness to serve as future caregivers for their grandparents. Undergraduate students (N = 209) completed a questionnaire in which they reported on a specific grandparent’s use of RMB and how willing they were to serve as future caregivers for that specific grandparent. Results of a multiple regression analysis provided partial support for the hypothesized positive relationships between grandparents’ use of RMB and grandchildren’s willingness to serve as future caregivers for their grandparents.  相似文献   

Online interaction across three contexts: an analysis of culture and technological affordances     

Todd L. Sandel  Richard Buttny  Mary Varghese 《Journal of Intercultural Communication Research》2019,48(1):52-71

Students were linked virtually across three contexts: U.S., Malaysia, and China. Differences emerged in how student-created messages were constructed and interpreted; these impacted perceived relational affiliation. Messages constructed by students in Malaysia and China exhibited casual talk, greater self-disclosure, requests for personal information, and greater use of emoticons/emoji. Interactions were perceived as informal, friendly, and positive. U.S. students’ messages often showed institutional talk, less self-disclosure, and more attention to the instructor-assigned task. Asian-U.S. student pairs perceived their interactions as formal, less friendly, and less positive. This study shows how online technologies may be afforded and shaped by culture and interaction.  相似文献

基于AHP的灰色关联分析法在企业竞争力评价中的应用   总被引：2，自引：1，他引：1  

陈涛 《内江师范学院学报》2008,23(8):58-61

将AHP法和灰色关联分析法相融合建立企业竞争力综合评价模型．以AHP法计算出准则层中各竞争力指标权重作为灰色关联分析法的待检模式向量,以方案层中各竞争力指标相对权重组成企业竞争力特征矩阵,再计算出灰色关联度,由此得到企业竞争力大小排序．通过实例分析说明这种融合方法具有可行性和科学性．  相似文献

农作物品种区域试验的结果能否从总体水平上客观真实地反映参试品种,与科学合理的评价方法密切相关。应用灰色关联度分析法和同异联系势分析法两种方法综合对河南省小麦区域试验2005-2006年度冬水组14个品系(种)的11个主要农艺性状进行了综合描述和量化评估,较为全面、客观地评价了参试品系(种)的优劣,结果表明同异联系势分析与灰色关联度分析结果基本一致,它们都反映出品系6、品系5、品系11综合农艺性状突出,综合性状较好。  相似文献   

Anatomy as a Model Environment for Acquiring Professional Competencies in Medicine: Experiences at Harvard Medical School     

Katherine G. McDaniel  Taylor Brown  Caitlin C. Radford  Cynthia H. McDermott  Trudy van Houten  Martha E. Katz  Dana A. Stearns  Sabine Hildebrandt 《Anatomical sciences education》2021,14(2):241-251

Anatomy education provides students with opportunities to learn structure and function of the human body, to acquire professional competencies such as teamwork, interpersonal skills, self-awareness, and to reflect on and practice medical ethics. The fulfillment of this wide potential can present challenges in courses that are part of an integrated curriculum and shorter than traditional courses. This new reality, together with students' increasing concern about the stresses within medical education, led to efforts at Harvard Medical School to implement practical steps toward an optimal learning environment in anatomy. These were based on core elements of ethical anatomy education and principles of trauma-informed care. Anatomy is conceptualized here as the “first clinical discipline,” with relational interactions between anatomical educators, medical students, and body donors/patients. Essential prerequisites for the implementation of this work were support by the medical school leadership, open partnership between engaged students and faculty, faculty coordination, and peer-teaching. Specific interventions included pre-course faculty development on course philosophy and invitations to students to share their thoughts on anatomy. Student responses were integrated in course introductions, combined with a pre-dissection laboratory visit, an introductory guide, and a module on the history and ethics of anatomy. During the course, team-building activities were scheduled, and self-reflection encouraged, for example, through written exercises, and elective life-body drawing. Students' responses to the interventions were overall positive, but need further evaluation. This first attempt of a systematic implementation of an optimal learning environment in anatomy led to the identification of areas in need of adjustment.  相似文献
