Social Networking Sites (SNSs) play an important role in our daily lives and the number of their users increases regularly. To understand how users can be satisfied in the complex digital environment of SNSs, this study examines how motivations and emotions combine with each other to explain high satisfaction. Users’ motivations comprise four attributes, entertainment, information, social-psychological, and convenience. Emotions are divided into their two main categories, that is positive and negative emotions. We draw on complexity and configuration theories, present a conceptual model along with propositions and perform a fuzzy-set qualitative comparative analysis (fsQCA). Through an empirically study with 582 SNSs users, we present eight combinations (configurations) of motivations and emotions that lead to high satisfaction, which highlight the role of high convenience, followed by entertainment and information motivations in being satisfied with SNSs. High satisfaction can be achieved both when positive and negative emotions are high and low, depending on how they combine users’ motivations. None of the factors are indispensable to explain high satisfaction on their own, instead they are insufficient but necessary parts of the causal combinations that explain high satisfaction. This study contributes in SNSs literature by extending current knowledge on how motivations and emotions combine to increase satisfaction, and by identifying specific patterns of users for whom these factors are important and influence greatly their satisfaction. 相似文献

第43届世界乒乓球锦标赛,中国选手邓亚萍、乔红等在面临欧亚外国选手及“海外兵团”有力挑战后,连闯数关,包揽世乒赛女子单打前三名,说明中国女队的技战术水平在世界乒坛仍占有较大优势,心理素质也日趋成熟,但中国女队也存在后备力量不理想,年轻选手心理素质不够稳定,技术风格不够凶狠等问题,需引起我们思想上足够的重视。 相似文献

This study explored how confidence in prior knowledge, self-efficacy, interest, and prior knowledge interact in conceptual change learning. One hundred and sixteen college students completed an assessment of confidence in prior knowledge, self-efficacy, interest, prior scientific understanding, and prior misconceptions before reading a refutation text on seasonal change. Students’ misconceptions and scientific understanding of seasonal change was then assessed before and after reading a refutation text, and again at a two week delayed posttest. Three profiles of students emerged based on their confidence in prior knowledge, self-efficacy, interest, prior scientific understanding, and prior misconceptions. The profiles included: (1) Low (low confidence, self-efficacy, interest, and prior scientific understanding and high prior misconceptions), (2) mixed (high confidence, self-efficacy, and interest, but low prior scientific understanding and high prior misconceptions), and (3) high (high confidence, self-efficacy, interest, and prior scientific understanding and low prior misconceptions). Results indicated that the mixed profile appeared to be most productive for conceptual change and that learner characteristics most productive for conceptual change learning may differ from those most productive in other learning situations. 相似文献

Purposes: This study applies the self-determination theory (SDT) to test the hypothesized relationships among perceived autonomy support from parents, physical education (PE) teachers, and peers, the fulfilment of psychological needs (i.e., autonomy, competence, and relatedness), autonomous motivation, and leisure-time physical activity of Chinese adolescents. Method: There are 255 grade six to eight student participants from four middle schools around Shanghai, China included in this study. An accelerometer was used to measure the moderate-to-vigorous physical activity (MVPA). The participants completed the questionnaires regarding SDT variables. The structural equation modelling was applied to examine the hypothesized relationships among the study variables. Results: The model of hypothesized relationships demonstrated a good fit with the data [X2?=?20.84, df?=?9, P?=?.01; CFI?=?0.98; IFI?=?0.98; SRMR?=?0.04; RMSEA?=?0.05]. The findings revealed that autonomy support from parents, PE teachers, and peers foster social conditions in which the three basic psychological needs can be met. In turn, autonomy, competence, and relatedness are positively associated with autonomous motivation for MVPA. The autonomous motivation positively relates to the MVPA time of adolescents. The three psychological needs partially mediate the influence of autonomy support from parents (β?=?0.18, P?<?.01; Bootstrap 95% CI?=?0.06–0.33) and teachers (β?=?0.17, P?<?.01; Bootstrap 95% CI?=?0.03–0.26) in the autonomous motivation. Conclusion: In conclusion, these findings support the applicability of SDT in understanding and promoting physical activity of Chinese adolescents. 相似文献

This study examined adolescents’ perceptions of peer and teacher supports in relation to internalized values, academic self-efficacy, efforts to learn, and goal orientations at the individual and classroom level in a sample of middle school (n = 169) and high school (n = 71) students from 6 schools (15 classrooms). Novel approaches to assessing classroom-level effects included use of coefficient of variation scores to capture consensus among student reports and use of cluster-robust standard errors to account for clustering. At the individual level, significance tests for indirect pathways and formal mediation indicated that relations between perceived peer expectations for prosocial behavior and effort and mastery orientation were mediated by internalized value; and, the relation between perceived emotional support from peers and effort was mediated by self-efficacy. At the classroom level, teachers who were perceived similarly by students with respect to provisions of emotional support also tended to have students who reported high levels of internalized value, and a high degree of student consensus concerning their teacher’s value for subject matter was related positively to their internalized value and effort. Consensus of student reports concerning internalized value was a negative predictor of performance orientation. 相似文献
