Audience management,online turbulence and lurking in social networking services: A transactional process of stress perspective

In social networking services (SNSs), users’ unclear understanding of the large and invisible audience increases the chances of online turbulence, which is a key source of SNS-induced stress. This growing phenomenon has gained increasing attention in academia and industry due to the undesirable consequences for users and SNS platforms. In this study, we draw from the transactional model of stress to examine how audience management strategies impact online turbulence and lead to neglected unintended audience concern and lurking. We also investigate the role of self-monitoring as a stress inhibitor. We test our model with data collected from 301 SNS users. The results show that the four types of audience management strategies have different effects on online turbulence, which significantly impacts neglected unintended audience concern especially when users have high self-monitoring skills. We believe that this work contributes, both from scientific and practical standpoints, to the understanding of the interventions and stressful responses of online turbulence in SNSs.     

基于专利引用跨越度计量的两国间间接创新合作机会发现

[目的/意义] 两个国家间的创新合作机会有些是显性直接的，有些是潜在间接的。在此试图构建一种计量和分析专利引用关系的方法，用于发现两国间潜在的间接创新合作机会。[方法/过程] 全球价值链上不同环节专利之间的引用关系中，蕴含着相互衔接、配套的间接合作关系，而不同环节的专利通常具有不同的功能，即IPC存在一定跨越度。因此，设计"专利引用跨越度"指标及算法，用于计量和筛选专利引用网络中"引用跨越度"达到预设阈值的专利引用关系，作为发现间接创新合作机会的基础数据。以新加坡在中国获得授权的发明专利为样本，基于专利引用跨越度计量并配合人工解读和识别，发现中新两国间一系列的间接创新合作机会。[结果/结论] 基于专利引用跨越度计量的两国间间接创新合作机会发现的方法，被实验检验为有效。     

The influence of maltreatment history and out-of-home-care on children’s language and social skills

This study examined the extent to which maltreatment history and the characteristics of out-of-home care correlated with the language and social skills of maltreated children. Participants in this study were 82 maltreated children aged between 5 and 12 years of age. All children were residing with state-designated carers in out-of-home-care. The children were presented with standardised tests assessing language and social skills. Results showed that the sample performed significantly below the normative mean on both tests. Correlation analyses showed social skills, but not language skills were correlated with aspects of maltreatment history. The education level of the state-designated carer/s was correlated with the children's language skills; higher education level was associated with higher language skills. The study provides evidence that at the group level, language and social skills are poor in maltreated children. However, gains in language skills might be made via the out-of-home-care environment. Improvements in the social skills of maltreated children may require additional support.     

Identifying the combinations of motivations and emotions for creating satisfied users in SNSs: An fsQCA approach

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.

Best of both worlds or refusal to comply? The rich kids of Tehran on Instagram

ABSTRACT

This article offers a textual analysis and semiotic reading of the Rich Kids of Tehran's (RKOT’s) Instagram page. Contributing to scholarship on Iranian youth media practices, this article interrogates how the RKOT navigate urban and rural space to engage in everyday processes of resistance against global and local systemic oppression. Grounding their visual representations on Instagram in historical and cultural context, the author questions how and when quotidian actions are transformed into political transgressions when posted on social media. This article emphasizes the RKOT's agency in shaping their brand by analyzing representations of gender performance, intertextuality, and national identity on Instagram.     

记忆场、传统村落与我们的责任——档案部门参与村落记忆场保护的价值与策略

传统村落拥有丰富的自然和文化资源,凝结着历史的记忆,是社会文明的直接见证者。随着城镇化进程的推进,传统村落逐步消融在时代的印迹里。为促进传统村落在新时代的焕发新生,文章借助法国历史学家皮埃尔·诺拉的记忆之场理论,指出传统村落在历史、时间、变迁中凝聚成具有象征意义的记忆场。在此基础上文章剖析了档案部门参与村落记忆场保护的意义,阐释了村落记忆场赓续乡村记忆、留住乡情乡愁、传承文化遗产的功能,并提出了档案部门就如何推动村落记忆场实现功能最大化的策略,以期使档案部门更好地承担起传承、保护、赓续传统村落的主体责任。

The balancing act of social enterprise: An IT emergence perspective

The significance of IT in the context of non-digital social enterprises (SEs) and its influence on the viability of such SEs have been less studied themes in information systems research. In the era of ubiquitous IT, SEs have increasing pressures to cope with the ever-dynamic technological domain while balancing their dual objectives. Data from a single revelatory case of Jaipur Rugs (JR), an SE situated in a developing country context (India), is used to fathom the peculiarities of the SE context with a focus on the sociomaterial phenomena of IT emergence. Using the three fundamental notions of sociomateriality theory (relationality, performativity, and practice) this interpretive study understands the mechanisms underlying the SE’s attempt to balance its financial and social sustainability objectives. Through the innovative use of IT, the SE establishes and maintains shared value, yielding stability and efficiency to the business (financial viability) while simultaneously ensuring scalability and effectiveness of their social impact. This study strengthens the perspective of IT as an emergent phenomenon situated in sociomaterial practices and fills a gap in organizational literature by examining such phenomenon in the rich context of SEs where achieving the balance between dual goals is increasingly dependent on non-human (IT) agents.
