Abstract
Purpose
Existing researches find that a gender difference exists in terms of Internet usage. In China, the singleton daughters resulting from China's one-child policy enjoy unprecedented parental support. The purpose of this paper is to investigate whether singleton daughters can, to some extent, break through the predicament of the digital divide.
Design/methodology/approach
The study collected data from a sample of 865 college students and obtained 811 valid questionnaires. Exploratory factor analysis (EFA) is used to identify clusters of Internet usage from the perspective of statistical associations in various daily online activities. Two-way ANOVA and mean-comparison tests are used to analyze how singleton and non-singleton students use the Internet differently.
Findings
This study finds that singleton female students showed no significant differences from male students in aspirational activities of informational, educational use and social media use, which means that singleton female students have caught up with male students in these activities. However, female college students from multi-child families were still found to be disadvantaged in those activities.
Originality/value
There is a lack of consensus on the classification of Internet activities. We used EFA to cluster the varieties of Internet activities into three types: utilitarian use, exploratory use and aspirational use. The three identified types of Internet usage require different degrees of user initiative. We argue that initiative provides a useful lens through which to classify Internet usage. In addition, this study is among the few studies to investigate the impact of the one-child policy on the gender digital divide.

Abstract
Purpose
A major paradigm shift focusing on the dark side of leadership has generated lots of concern for organizations as leadership has cascading effects on employees’ behaviour. This study aims to understand negative behaviours in the organization as a system of interrelated interaction initiated from the top which trickles down to employees.
Design/methodology/approach
Drawing on the theories of social exchange and norms of reciprocity, social learning and displaced aggression, this study models how and when abusive supervision relates to employees’ task performance. The model is empirically tested and extended to cover mediation and moderation processes. Drawing data from 218 bank supervisors and employees, this study uses the structural equation modelling to analyse a trickle-down model of abusive supervision.
Findings
Results from multi-waved, multi-sourced data indicated a mediating effect on the abusive supervision–performance relationships and provided support for employees’ guilt proneness and emotional dissonance as moderators. Overall, the results provided support for a moderated mediation relationship in the trickle-down model.
Originality/value
This study provides new knowledge into the potential boundary conditions of employees’ guilt proneness and emotional dissonance in affecting the relationship between abusive supervision, counterproductive work behaviour and task performance.

Abstract
Purpose
Path planning is an important part of three-dimensional (3D) printing data processing technology. This study aims to propose a new path planning method based on a discontinuous grid partition algorithm of point cloud for in situ printing.
Design/methodology/approach
Three types of parameters (i.e. structural, process and path interruption parameters) were designed to establish the algorithm model with the path error and the computation amount as the dependent variables. The path error (i.e. boundary error and internal error) was further studied and the influence of each parameter on the path point density was analyzed quantitatively. The feasibility of this method was verified by skin in situ printing experiments.
Findings
Path point density was positively correlated with Grid_size and negatively related to other parameters. Point_space, Sparsity and Line_space had greater influence on path point density than Indentation and Grid_size. In skin in situ printing experiment, two layers of orthogonal printing path were generated, and the material was printed accurately in the defect, which proved the feasibility of this method.
Originality/value
This study proposed a new path planning method that converted 3D point cloud data to a printing path directly, providing a new path planning solution for in situ printing. The discontinuous grid partition algorithm achieved controllability of the path planning accuracy and computation amount that could be applied to different processes.

Abstract
Purpose
This paper aims to assess the impact of research in the field of scientometrics by using the altmetrics (social media metrics) approach.
Design/methodology/approach
This is an applied study which uses scientometric and altmetrics methods. The research population consists of the studies and their citations published in the two core journals (Scientometrics and Journal of Informetrics) in a period of five years (included 1,738 papers and 11,504 citations). Collecting and extracting the studies directly was carried from Springer and ScienceDirect databases. The Altmetric Explorer, a service provided by Altmetric.com, was used to collect data on studies from various sources (www.altmetric.com/). The research studies with the altmetric scores were identified (included 830 papers). The altmetric scores represent the quantity and quality of attention that the study has received on social media. The association between altmetric scores and citation indicators was investigated by using correlation tests.
Findings
The findings indicated a significant, positive and weak statistical relationship between the number of citations of the studies published in the field of scientometrics and the altmetric scores of these studies, as well as the number of readers of these studies in the two social networks (Mendeley and Citeulike) with the number of their citations. In this study, there was no statistically significant relationship between the number of citations of the studies and the number of readers on Twitter. In sum, the above findings suggest that some social networks and their indices can be representations of the impact of scientific papers, similar citations. However, owing to the weakness of the correlation coefficients, the replacement of these two categories of indicators is not recommended, but it is possible to use the altmetrics indicators as complementary scientometrics indicators in evaluating the impact of research.
Originality/value
Investigating the impact of research on social media can reflect the social impact of research and can also be useful for libraries, universities, and research organizations in planning, budgeting, and resource allocation processes.

Abstract
This chapter depicts the burden of suicidal behavior among African American males. It describes the public health approach to preventing suicidal behavior among African American males. This approach includes assessing and describing the problem; identifying causes or risk and protective factors; developing and evaluating programs and policies; and implementing and disseminating findings and activities. The chapter provides a review of the epidemiology of fatal and non-fatal suicidal behavior; a summary of what is known about the risk and protective factors of the problem; and a descriptive analysis of the circumstances associated with suicides among young African American males is presented. Lastly, the authors give a summary of evidenced-based prevention programs which could be applied in preventing male suicidal behavior.

Abstract
Purpose
Prior research has documented that managers take opportunistic timing activities to influence the exercise prices of executive stock options (ESOs). This paper aims to add to the literature by investigating whether such behavior is mitigated by the exercise price regulation of China.
Design/methodology/approach
Using a sample of 132 ESO reports between 2006 and 2010 in China, the authors explore whether the regulation takes effect by examining stock price movements and companies' information disclosures around the report dates.
Findings
Consistent with the conjecture that the regulation could not effectively limit managers' opportunistic behavior, the authors find that the abnormal returns decrease slowly until ten trading days before the report dates, increase gradually subsequently, and rise dramatically just after the report dates. Particularly, the return pattern is more pronounced when corporate governance is weaker. The authors also find that managers opportunistically time ESO reports based on their private information. In particular, more (less) favorable (negative) news announcements occur after the report dates than beforehand. Additionally, compared to earnings announcements, managers prefer to time ESO reports with information about forward‐looking earnings and security issuances.
Originality/value
These results suggest that the regulation could not effectively constrain managers from influencing the exercise prices. The paper also provides evidence that imperfect regulations under asymmetric information may lead to additional agency costs, especially when corporate governance is weak. The authors' findings can contribute to the improvement of regulations on ESOs.

Abstract
Purpose
Knowledge adoption is the key to effective knowledge exchange in virtual question-and-answer (Q&A) communities. Although previous studies have examined the effects of knowledge content, knowledge source credibility and the personal characteristics of knowledge seekers on knowledge adoption in virtual Q&A communities from a static perspective, the impact of answer deviation on knowledge adoption has rarely been explored from a context-based perspective. The purpose of this study is to explore the impact of two-way deviation on knowledge adoption in virtual Q&A communities, with the aim of expanding the understanding of knowledge exchange and community management.
Design/methodology/approach
The same question and the same answerer often yield multiple answers. Knowledge seekers usually read multiple answers to make adoption decisions. The impact of deviations among answers on knowledge seekers' knowledge adoption is critical. From a context-based perspective, a research model of the impact of the deviation of horizontal and vertical answers on knowledge adoption is established based on the heuristic-systematic model (HSM) and empirically examined with 88,287 Q&A data points and answerer data collected from Zhihu. Additionally, the moderation effects of static factors such as answerer reputation and answer length are examined.
Findings
The negative binomial regression results show that the content and emotion deviation of horizontal answers negatively affect knowledge seekers' knowledge adoption. The content deviation of vertical answers is negatively associated with knowledge adoption, while the emotion deviation of vertical answers is positively related to knowledge adoption. Moreover, answerer reputation positively moderates the negative effect of the emotion deviation of horizontal answers on knowledge adoption. Answer length weakens the negative correlation between the content deviation of horizontal and vertical answers and knowledge adoption.
Originality/value
This study extends previous research on knowledge adoption from a static perspective to a context-based perspective. Moreover, information deviation is expanded from a one-way variable to a two-way variable. The combined effects of static and contextual factors on knowledge adoption are further uncovered. This study can not only help knowledge seekers identify the best answers but also help virtual Q&A community managers optimize community design and operation to reduce the cost of knowledge search and improve the efficiency of knowledge exchange.
