The purpose of this paper is to investigate the interrelationships between internet connectedness, online gaming, internet addiction symptoms, and academic performance decrement among the internet-dependent young people in China.

A paper-based survey was conducted among the young clients in one of the earliest and largest internet addiction clinics in China. A total of 594 in-patients (mean age=17.76 y) voluntarily participated in this study.

By adopting the concept of internet connectedness, this study explored the internet use patterns among the young internet addicts, for example, internet café patrons and those who use internet with more goals or higher degree of internet adhesiveness had more internet addiction symptoms. Online gaming was found to play a significant role in the development of internet addiction. As expected, the level of internet addiction is significantly linked to academic performance decrement. Consistent with previous studies, males showed higher degree of internet connectedness and online game usage than females. Noticeably, the moderation effect of online game playing and the mediating effect of internet addiction were also tested.

This research is focussed on the internet-dependent group, thus the generalizability of the results need to be interpreted with caution.

This study provides insight for parents, educators, health professionals, and policy makers regarding treatment and intervention for internet addiction among young people in China.

Since very little research has been done focussing on diagnosed internet-dependent group, this paper scores as a pioneering study of its kind in China.

As the excessive lifting force can lead to catwalk rollover and well site accidents, the lifting process boundary conditions and structural parameters have a significant effect lifting force, it is important to analysis the structural parameters on the maximum lifting force in the lifting process of power catwalk.

A new model is proposed to analyze the influence of structure parameters on its lifting force for lifting power catwalk in this paper, and the geometric and dynamic equations are established according to the different boundary conditions in different stages. In addition, the establishment of dynamics equations is based on D'Alembert's principle. To solve the model, dynamic analysis software is developed, which uses c # call MATLAB to solve the geometric and dynamic equations. The maximum lifting force is analyzed and optimized according to the software, the influence of structural parameters on the maximum lifting force is obtained and the correctness of the optimization is proved by experiments.

The best value of offset e is 0. The length of L22 should as small as possible while the installation size of the end of the conveying arm are guaranteed. The length of L1 should as small as possible while ensuring the not exceed the maximum value. The maximum lifting force remain the same in the second phase, the maximum lifting force decreases with the increase of Lcp, Lcpshould as small as possible. The maximum pressure of the hydraulic oil dropped by an average of 13.62% under optimized parameters.

This paper provides a theoretical basis for the selection of hydraulic winch, which also provides the theoretical basis and data support for the design and optimization of the structural parameters of the power catwalk.

A new model is proposed to analyze the lifting force of lifting power catwalk. The model takes into account the inertia force of the structure, development of dynamics software and analysis and optimization of structural parameters. The maximum lifting force is analyzed and optimized according to the software, the influence of structural parameters on the maximum lifting force is obtained and the correctness of the optimization is proved by experiments.

The purpose of this paper is to investigate the mediating role of psychological needs in the association between individualism and internet addiction.

A mixed-method design was used by comprising of 602 college students’ (70.3 percent women) responses obtained through the Individualism-Collectivism Survey, New Needs Assessment Questionnaire, and Internet Addiction Scale. Structural equation modeling techniques were used to investigate the theoretical relationships among the constructs. Constant comparative method was employed to analyze qualitative data that resulted from the transcription of semi-structured interviews with 12 field experts.

Quantitative results showed that individualism has a significant effect on internet addiction through affiliation, dominance, achievement, and autonomy (i.e. psychological needs). As students’ needs for dominance, achievement, and autonomy increased their internet addiction levels decreased. However, increase in the need of affiliation led to increase in the likelihood of internet addiction. Qualitative findings suggested alternative ways to satisfy psychological needs in socially more proper ways.

Psychological needs and internet addiction have long been investigated both independently and in relation to each other. However, the investigation of espoused culture (i.e. individualism) in relation to psychological needs and internet addiction is relatively recent. A review of the recent literature showed that an investigation of the mediating role of psychological needs in the effect of individualism on internet addiction is highly original. Moreover, initial quantitative results and follow-up qualitative findings help the authors understand psychological needs underlying internet addiction and suggest socially more appropriate means to satisfy these needs. Findings have theoretical values for researchers as well as practical values for those who work with students.

This purpose of this paper is to examine the relationship between workplace ostracism and cyberloafing, based on the premise of conservation of resources theory. Emotional exhaustion is tested as a mediator between workplace ostracism and cyberloafing, whereas facilitating conditions are predicted as a moderator that influences employees’ reaction to ostracism.

Survey data were collected via the online platform Amazon Mechanical Turk. Partial least squares analysis, a variance-based structural equation modelling, was utilised to verify the research model.

The results show that both workplace ostracism and emotional exhaustion have a significant positive relationship with cyberloafing. Likewise, emotional exhaustion partially mediates the relationship between workplace ostracism and cyberloafing. Interestingly, facilitating conditions do not moderate the emotional exhaustion–cyberloafing relationship but do moderate the ostracism–cyberloafing relationship. Counterintuitively, the relationship between workplace ostracism and cyberloafing becomes stronger when facilitating conditions are high. A post hoc analysis has been conducted using PROCESS Macro to test the conditional indirect effect but was found not significant.

Previous studies have revealed the association between workplace ostracism with various negative work behaviours, such as knowledge hiding, knowledge hoarding and counterproductive work behaviours. This study has successfully identified that workplace ostracism can also result in cyberloafing, which has not been delved into previous works. This has subsequently provided managers with new perspectives regarding why employees engage in non-work-related online activities at work.

Cyberloafing is the personal use of internet while at work. The purpose of this paper is to identify the factors affecting cyberloafing between public and private sector organizations.

This study uses the multiple motivational factors with the help of a theoretical paradigm, renowned as theory of interpersonal behavior (TIB). Data were collected through questionnaire to investigate the different behavioral factors between the public and private sector organizations. PLS path modeling and PLS-MGA are used to access the results on SMARTPLS 2.0 software.

Results show that the three factors of habit, intention, and social influences taken from the TIB model are important and have a higher path coefficient in a public sector organization setting. The factors of affect, facilitating condition and perceived consequences from TIB are greater in a private sector organization and have a higher path coefficient. By contrast, in multiple group analysis, results show that some factors are more predictive of cyberloafing behavior in a public sector organization, whereas other factors are more predictive for a private sector organization.

The findings of the current research are beneficial for both organizations and contribute toward policy-making decisions. These results help the managers of public and private sector organizations to decide how to control cyberloafing behavior by focusing on the important factors that lead to it.

This study shows strong and significant differences between the two types of organizations in terms of path coefficient. This implies that cyberloafing factors have different impacts on different organizations. The study fills an important gap in comparing public and private sector organizations with respect to cyberloafing behavior and clarifying which factors are more effective in predicting cyberloafing behavior according to type of organization. The paper is of great value for both kinds of organizations that face cyberloafing behavior issues.
