知识更新对员工创造力的影响     

李海  马丽  于然 《科研管理》2021,42(10):182-190

知识员工是企业赖以生存和发展的宝贵财富。随着知识老化速度日益加快,知识更新成为知识员工普遍面临的压力。基于挑战—阻断性压力分类理论和压力交互理论,探讨知识更新要求对女性知识员工创造力的影响,分析了挑战性压力评估和个体技能发展的链式中介作用和工作家庭冲突的调节作用。运用结构方程模型和Bootstrapping方法对假设进行检验,结果表明：知识更新要求对员工创造力有显著正向影响,包括直接影响和间接影响;在间接影响方面,挑战性压力评估和个体技能发展在知识更新要求与员工创造力关系中起部分链式中介作用;在直接影响方面,工作家庭冲突在知识更新要求与员工创造力关系中起调节作用。  相似文献   

有氧健身操和力量训练对年轻超重和肥胖男性体能与血液改变的对比研究*     

谢佳辉  方〓奇   《广州体育学院学报》2019,(5):103-106

国内肥胖和超重现象日趋严重,运动减肥中常用的两种方法：有氧健身操和力量练习方法,这两种训练方式如何改变年轻超重和肥胖男性的身体形态和机能？文章试图来给予正在利用这两类运动方式健身和减肥的年轻超重或者肥胖者一些科学建议,从而能够根据自身身体状态和需求来科学健身。研究方法：9周训练时间,分3组平行进行,分别为有氧健身操组、力量训练组和对照组,训练一般选在下午5点进行,每次训练90min,5次/周。实验前后分别测试受试者的BMI,体脂率,最大摄氧量,耐力,握力和弹跳力,以及血清中的白细胞介素1β(IL-1β)和6(IL-6),以及肿瘤坏死因子α(TNF-α),并统计分析实验数据,t检验实验前后和组间的差异。实验结果：有氧健身操和力量训练都能减少年轻超重和肥胖男性的BMI和体脂率,并增加肌肉量、握力和弹跳力,但有氧健身操改善受训者的心肺功能（最大摄氧量和耐力）的能力要强于力量训练。对于血清中的致炎因子影响来说,两种不同的训练方式起着完全相反的作用：有氧健身操能够降低致炎因子水平（IL-1β,IL-6,TNF-α）,但是力量训练却使致炎因子的水平增加。结论：建议想增加肌肉量的年轻超重和肥胖男性在使用力量训练的同时,结合有氧健身操的锻炼方法,使身体逐渐恢复健康状态。  相似文献

Effects of strength and endurance exercise order on endocrine responses to concurrent training     

Thomas W. Jones  Glyn Howatson  Mark Russell 《European Journal of Sport Science》2017,17(3):326-334

The present study examined the effect of strength and endurance training order on the endocrine milieu associated with strength development and performance during concurrent training. A randomised, between-groups design was employed with 30 recreationally resistance-trained males completing one of four acute experimental training protocols; strength training (ST), strength followed by endurance training (ST-END), endurance followed by strength training (END-ST) or no training (CON). Blood samples were taken before each respective exercise protocol, immediately upon cessation of exercise, and 1?h post cessation of exercise. Blood samples were subsequently analysed for total testosterone, cortisol and lactate concentrations. Ability to maintain 80% 1RM during strength training was better in ST and ST-END than END-ST (both p?<?.05). Immediately following the respective exercise protocols all training interventions elicited significant increases in testosterone (p?<?.05). ST and END-ST resulted in greater increases in cortisol than ST-END (both p?<?.05). The testosterone:cortisol ratio was similar following the respective exercise protocols. Blood lactate concentrations post-training were greater following END-ST and ST than ST-END (both p?<?.05). Conducting endurance exercise prior to strength training resulted in impaired strength training performance. Blood cortisol and lactate concentrations were greater when endurance training was conducted prior to strength training than vice versa. As such, it may be suggested that conducting endurance prior to strength training may result in acute unfavourable responses to strength training when strength training is conducted with high loads.  相似文献   

Conflict among athletes and their coaches: what is the theory and research so far?     

Svenja Wachsmuth  Sophia Jowett  Chris G. Harwood 《International review of sport and exercise psychology》2017,10(1):84-107

Although social and personal relationships are vital for productivity, health and wellbeing, conflict is inevitable and is likely to cause upset and hurt feelings as well as anxiety and distrust. Despite the potentially central role of interpersonal conflict in sport, researchers have yet to pay concerted attention to exploring the nature of conflict, its antecedents and consequences. Following a thorough literature search 80 research papers were identified, of which only a small number (6) studied interpersonal conflict directly, most captured dysfunctional interpersonal processes such as breakdown of communication. The current review aims to provide a critical summary of the existing literature around the psychological construct of interpersonal conflict, including its antecedents, management strategies and outcomes within the context of coach–athlete relationships as well as other relational contexts in sport. Based on the relevant literature, a framework of interpersonal conflict is proposed, which includes a specific focus on a key dyad within sport coaching – namely the coach–athlete dyad. Future research directions and potential practical implications for sport psychology consultants, coach educators, coaches and athletes as well as other stakeholders are discussed.  相似文献   

A Test of the Relationships between Host and Home National Involvements and the Preferences for Intercultural Conflict Management Styles     

Deepa Oommen 《Journal of Intercultural Communication Research》2017,46(4):314-329

This study focused on the relationships between host national (host interpersonal communication) and home national (ethnic interpersonal communication) involvements and preferences for conflict management styles in the context of a conflict with a member of the host culture. Two hypotheses that examined the relationships between these variables and the preferences for the integrating, the compromising, the avoiding, the obliging and the dominating styles were proposed. Survey data from two hundred and sixty-nine, international and exchange, students were analyzed. The results revealed that the level of host national involvement positively predicted the preferences for the integrating and the obliging styles, and the level of home national involvement positively predicted the preference for the avoiding style. These findings suggest the need to consider contextual influences in understanding the complexities that underlie intercultural communication and adaptation.  相似文献   

冲突与治理：广场舞现象的社会学审视     

舒刚民 《北京体育大学学报》2017,40(8):27-33

摘要：在社会老龄化和城镇居民迁居的时代语境下,广场舞不仅仅是一个关注全民体质健康的话题,更是一个聚焦民生,传递社会正能量,推动社会和谐发展的问题。为了更好地开展全民健身活动,主要采用文献资料法,以科赛的功能主义冲突理论为基础,对广场舞现象进行研究。认为：广场舞现象反映的是人民群众对传统文化的记忆和觉醒,以及对当代生活的文化诉求。广场舞兴盛的根源是人口老龄化视角下,中老年群体对体质健康的担忧,对养老支持和公共医疗保障的呐喊。同时,也是城镇化建设和城市迁居背景下,中老年群体对构建新邻里关系的渴望。广场舞引发的社会冲突,是为了让我们更加关注城市公共空间的供给与规划,更加关注民生健康需求、人权利益诉求以及公共道德的培育。并进一步从政府公共治理、公民自治以及社会协同治理3个方面提出相应的对策,为广场舞现象的社会治理提供参考。  相似文献   

社会生态理论视角下女性体育锻炼行为的影响因素研究     

唐芝 《福建体育科技》2017,36(1)

运用文献资料法对1996-2015年有关女性体育锻炼行为的文献进行了回顾,梳理了当前研究成果中所涉及的相关影响因素,以行为的社会生态模型为指导,从个体内在因素、社会环境、物理环境三个维度对相关因素进行了归纳与分析,并从时间冲突、精力冲突、角色形象冲突三方面探讨了影响女性体育锻炼行为的深层原因。研究认为:女性的体育锻炼行为是受到个体内在因素和外部环境因素的共同影响,要提高女性的体育参与,应该同时从这两方面进行干预和改进。  相似文献   

Malay(sian)’s image in Indonesian media prior to Konfrontasi era December 1962     

Yerry Wirawan 《Inter-Asia Cultural Studies》2017,18(3):454-462

This article presents the Malay(sian)’s image in Indonesian media in the early days of the Indonesia–Malaysia conflict at the beginning of 1960s. The dispute started when Tunku Abdul Rahman announced his plan to include Singapore, Brunei, Sarawak and North Borneo into the Federation of Malaya. Yet Indonesia regarded it as the British’s neocolonialist project. Left-wing nationalists expressed their opposition to this plan in their daily, Bintang Timur, with illustrations made by Delsy Syamsumar (1935-2001). His artworks may represent how Malaysia was seen by Indonesian artists during the dispute. On the other hand, most of Syamsumar’s artworks demonstrate his sympathy with Azahari, Borneo’s local political leader, who staged the insurgence against the plan on 8 December 1962. This article intends to highlight Syamsumar’s pioneering artworks, picturing the Indonesia–Malaysia dispute published in Bintang Timur in December 1962.  相似文献
