Prior literature suggests that social media users are increasingly experiencing social media fatigue. Only recently have scholars undertaken empirical studies to investigate its antecedents and outcomes to better understand the impact of fatigue on social media users. To further this understanding, the present study has conducted a cross-sectional survey with 1552 users. The Stress-Strain-Outcome (SSO) theoretical framework is applied to examine if privacy concerns, self-disclosure, parental mediation strategies, and decrement in academic performance due to social media use correlate with social media fatigue. Two forms of fatigue are considered, namely, fatigue due to social networking site (SNS) and mobile instant messaging (MIM) use. The study results suggest that privacy concerns, self-disclosure, parental encouragement and worry significantly and positively correlate with SNS and MIM fatigue. Parental permission and parental monitoring are either not or lowly associated with fatigue. In addition to this, SNS and MIM fatigue positively correlated with the tendency to experience academic decrement due to social media use. The antecedents and consequences of social media fatigue were similar for SNS and MIM users. Moreover, students perceived their parents to be more open to their MIM use, and they had higher self-disclosure in MIM than in SNS. The study concludes with significant implications for practitioners, policy makers as well as service designers. 相似文献

在C语言的众多运算符中,最难理解、使用时最易得到模棱两可结果的是自增、自减运算符。就这两个运算符在程序中的具体使用进行了详细的分析,不管是自增还是自减,前置运算符是"先变后用",后置运算符是"先用后变"。但是C语言的灵活性也容易使程序费解,不同的编译环境可能导致处理结果不同。 相似文献

在高级语言程序设计中,自增和自减运算一直是较为复杂的运算。尤其当自增和自减出现次数较多时,对于不同的高级程序IDE（IntegratedDevelopment,集成开发环境）,同样的程序,结果却不尽相同。本文给出了对比运算结果,并详细分析了原因。 相似文献

Java语言作为一种用于网络编程的纯面向对象的程序设计语言，随着互联网络的延伸而风靡世界。在Java语言的学习中，抓住难点运用比较的方法无疑会事半功倍。Java语言是由C语言演变发展而来的，C语言中提供的运算符几乎完全适合于Java语言，但具体用法上又有本质的区别。通过典型例子程序的设计、运行，来比较学习，是掌握一门新的计算机语言的最佳途径。 相似文献

近年来我国经济领域中服务和"知识"部门的迅速增长,大大改变了合并和收购交易中所产生商誉数额的性质和范围,再加上合并和收购交易规模的扩大,导致了公司财务报表中商誉价值的急剧增加.然而外购商誉作为一种无形资产究竟是进行减值还是摊销一直是会计理论界的研究热点.在对中外会计准则比较分析后发现商誉减值是大势所趋,并在此基础上提出我国商誉减值规定与其它相关会计准则的协调问题,同时指出商誉减值方面仍待研究的问题. 相似文献

Abstract The purpose of this investigation was to test the basic tenets of consolidation theory by studying the relationship between arousal and the performance and learning of a pursuit rotor task. Ninety-six subjects (48 men and 48 women) were randomly assigned to one of three induced arousal conditions (control, failure-feedback, and electrical shock). Subjects were given twenty-one 20-second acquisition trials under induced arousal conditions, followed 24 or 48 hours later by nine trials in the absence of induced arousal (trials 22–30). The Spielberger A-trait test was administered before the 21 acquisition trials and the A-state test was given afterward. The results of the A-trait test revealed that arousal conditions were equal in terms of normal anxiety levels, while results of the A-state test demonstrated that subjects under induced arousal conditions were indeed stressed (had higher levels of state anxiety). The 21 acquisition trials (seven three-trial blocks) were analyzed using time on target (TOT) scores to determine the effects of arousal on performance. The results of this analysis revealed reliable differences for sex and trial blocks, but not for arousal. A significant triple interaction among the three main effects was primarily caused by a decrement in performance by the female subjects who received failure-feedback. TOT recall scores failed to reveal a facilitative effect due to arousal as predicted by perseverative consolidation theory. In summary, the results of the investigation provided partial support for the action decrement notion but none for the action increment notion of consolidation theory. 相似文献

Warm‐up decrement (WUD), a phenomenon associated with motor behaviour, is the temporary decrement that occurs when performance resumes after a period of inactivity. The purpose of this study was to examine the extent to which observing a model while concerned about one's own subsequent performance (e.g. a substitute about to enter the sport contest) influences WUD. The subjects were randomly assigned to one of four conditions: (1) observing an ego‐involved model demonstrate the criterion skill, (2) observing a model while not ego‐involved, (3) ego involvement without modelling and (4) resting (control). Performance outcome (accuracy) and arousal (cognitive and somatic) were assessed. The results of the study indicated that only the combined ego involvement plus modelling condition eliminated WUD. Positive rather than negative emotions and heart rate increased significantly for these subjects after rest. In contrast, the other conditions each exhibited WUD. Heart rate was significantly higher in the ‘model and ego’ and ‘ego only’ groups as opposed to ‘modelling only’ and rest. Implications for using cognitive strategies while observing competitors just prior to entering the contest on reducing WUD are discussed. 相似文献
