Mobile--> commerce (m-commerce) has become increasingly important for organizations attempting to grow revenue by expanding into international markets. However, for multinational mobile retailers (m-retailers), one of the greatest challenges lies in carefully managing their websites across multiple national markets. This work advances cross-national research on m-retailing by (1) examining how value dimensions shape m-shoppers’ motivations, (2) analyzing differential effects of hedonic and utilitarian motivations on intention and habit, and (3) examining the competing roles of conscious (intentional) and unconscious (habitual) m-commerce use drivers across developed and developing countries. This research also examines the moderating role of m-commerce readiness at the country level on the effect of motivation on intention and habit, along with their impact on m-commerce use. Based on data from 1,975 m-shoppers in nine countries (Australia, Bangladesh, Brazil, India, Pakistan, Singapore, the United Kingdom, the United States, and Vietnam) across four continents, the results demonstrate differential relationships: consumers at an advanced (early) readiness stage are more likely to be hedonism-motivated (utility-motivated) when using m-commerce and tend to use it intentionally/consciously (habitually/unconsciously). In addition to advancing knowledge about m-commerce from a scientific perspective, the findings can help multinational firms decide whether to standardize or adapt m-shopping experiences when internationalizing.  相似文献

Extensive research has demonstrated the benefits of need-supportive teaching, but minimal research has examined social factors that may constrain these benefits. One factor that students experience contemporaneously to need-supportive teaching is classroom disruption. Perceived classroom disruption is a barrier to quality teaching and learning, especially in science, and may be a negative moderator of perceived need-supportive teaching. Using structural equation modelling (N = 14,530 students), this investigation examines the extent to which perceived need-supportive teaching and perceived classroom disruption uniquely predicted students' science self-efficacy, participation, and achievement; as well as the extent to which perceived classroom disruption moderates the associations between perceived need-supportive teaching and these outcomes. Findings revealed that perceived need-supportive teaching was positively associated with all outcomes. Perceived classroom disruption was negatively associated with self-efficacy and achievement and attenuated the positive association between perceived need-support and achievement. These results provide insight about the boundary conditions of need-supportive teaching.  相似文献

The influence of achievement goals and social goals on help-seeking from peers in an academic context was examined in two studies. A total of 551 high school students participated in the two studies. The results across the studies demonstrated strong convergence, revealing that mastery-approach, mastery-avoidance, and friendship-approach goals were positive predictors of instrumental help-seeking, whereas performance-avoidance and friendship-avoidance goals were negative predictors. Study 2 additionally demonstrated that attitudes toward help-seeking mediate the influence of achievement and social goals on instrumental help-seeking. These results add to the body of work investigating achievement and social motivation together to more fully understand motivational influences on academic outcomes.  相似文献

冷战结束后,波美密切关系是“威胁平衡”和“利益平衡”的产物。对波兰而言,一方面是为了制衡外部威胁,即主要通过美国的力量平衡来自周边大国的安全威胁,实现安全保障;另一方面是为了通过追随美国谋求多层面的国家利益。对于美国来说,则能够从中获得较大的国际战略空间和行动的自由,在某种程度上实现钳制欧、俄的战略需要。同时,波美关系也诠释了在大国主宰的国际权力政治中,中小国家有的不只是悲剧,还有机遇和喜剧。  相似文献

本研究基于领导-成员交换理论和社会支配理论,在等级制度和高权力距离的中国文化背景下,从地位竞争视角出发研究员工主动性行为、领导-成员交换关系、领导地位威胁感知与个体创新绩效之间的关系。基于13个组织的630套上下级配对问卷数据,采用层级线性回归模型对假设进行检验,本研究发现员工主动性行为正向影响其创新绩效,领导-成员交换关系中介了二者之间的正向关系,领导地位威胁感知削弱了员工主动性行为与创新绩效、员工主动性行为与领导-成员交换关系之间的正向关系。研究结果为员工主动性行为的研究提供了新的视角和框架,同时对企业管理实践有一定的现实意义。  相似文献

应用主观疲劳量表(RPE)评价训练负荷的过程是一个心理生理过程,量化结果具有较大的主观性和不确定性,需将RPE训练负荷量化结果与生理指标测试结果进行结合分析。对16名大学生足球运动员的多次训练进行跟踪,采集每名运动员每次训练的训练前RPE值、训练后RPE值和整个训练过程的实时心率;采取训练后RPE值(Foster1算法)和训练累积RPE值(Foster2算法),4种心率算法(Banister1、Banister2、Edwards和Stagno)对每名运动员每次训练的内部负荷进行测算;采用相关分析,对两种RPE算法所得每名运动员每次训练的内部训练负荷值与4种心率算法所得的内部训练负荷值的相关性进行检验。显示:两种RPE算法估算的运动负荷:与Banister1算法测算出的相关性平均分别为0.91和0.79;与Banister2算法测算出的相关性平均分别为0.62和0.57;与Edwards算法测算出的相关性平均分别为0.75和0.69;与Stagno算法测算出的相关性平均分别为0.55和0.54。显示:RPE能够有效地量化评估足球运动员的训练负荷,且“训练后RPE值”比“训练累积RPE值”能更加准确地反映足球运动员的训练负荷。  相似文献

Previous research demonstrates that sports coaching is a stressful activity. This article investigates coaches’ challenge and threat cognitive appraisals of stressful situations and their impact on coaching behaviour, using Blascovich and Mendes’ (2000) biopsychosocial model as a theoretical framework. A cross-sectional correlational design was utilised to examine the relationships between irrational beliefs (Shortened general attitude and belief scale), challenge and threat appraisals (Appraisal of life events scale), and coaching behaviours (Leadership scale for sports) of 105 professional football academy coaches. Findings reveal significant positive associations between challenge appraisals and social support, and between threat appraisals and autocratic behaviour, and a significant negative association between threat appraisals and positive feedback. Results also show that higher irrational beliefs are associated with greater threat, and lesser challenge cognitive appraisals. However, no associations were revealed between irrational beliefs and challenge cognitive appraisals. Additionally, findings demonstrate a positive relationship between age and training and instruction. Results suggest that practitioners should help coaches to appraise stressful situations as a challenge to promote positive coaching behaviours.  相似文献

The present study formulated a new theoretical model predicting emigration intentions in diaspora populations and tested it among Jews living in Russia. The study sample consisted of Jews and their relatives living in the vicinity of five large cities in Russia (n = 824). The results obtained demonstrated that a more negative attitude toward the country of residence and a more positive attitude toward the historical homeland were associated with stronger emigration intentions. A higher preference for the self-enhancement values and a lower preference for the conservation values were associated with stronger emigration intentions. The effect of the self-enhancement values on emigration intentions was complex: while their direct effect was positive, their indirect effect (through attitude toward Russia) was negative. The effect of the conservation values on emigration intentions was indirect (through attitudes toward Russia and Israel). Perceived socioeconomic conditions in the country of residence affected emigration intentions indirectly, through attitude toward Russia, whereby a higher level of perceived discrimination and a lower level of perceived economic conditions were associated with a less positive attitude toward Russia and stronger emigration intentions. Jewish identification also affected emigration intentions indirectly, through its positive connection with attitude toward Israel. Age negatively affected emigration intentions, both directly and indirectly (through its effect on values and perceived economic conditions). Religiosity and family ethnic composition affected emigration intentions indirectly, whereby a lower level of religiosity and a higher proportion of Jewish relatives in the family were associated with stronger emigration intentions.  相似文献
