How do employees prioritise when they schedule their own shifts?

We investigated how employees prioritised when they scheduled their own shifts and whether priorities depended on age, gender, educational level, cohabitation and health status. We used cross-sectional questionnaire data from the follow-up survey of an intervention study investigating the effect of self-scheduling (n = 317). Intervention group participants were asked about their priorities when scheduling their own shifts succeeded by 17 items covering family/private life, economy, job content, health and sleep. At least half of the participants reported that they were giving high priority to their family life, having consecutive time off, leisure-time activities, rest between shifts, sleep, regularity of their everyday life, health and that the work schedule balanced. Thus, employees consider both their own and the workplace's needs when they have the opportunity to schedule their own shifts. Age, gender, cohabitation and health status were all significantly associated with at least one of these priorities.

Practitioner Summary: Intervention studies report limited health effects of self-scheduling. Therefore, we investigated to what extent employees prioritise their health and recuperation when scheduling their own shifts. We found that employees not only consider both their health and family but also the workplace's needs when they schedule their own shifts.     

Impact of online resources on informal learners: Parents’ perception of their parenting skills

The Internet and Web technology development have opened up new ways for people to communicate, gain new information and increase their knowledge. One particular area of interest is that of using online resources to empower informal learners to increase their knowledge at their own time and space. One could look at an online resource as a public library being brought to the homes of such informal learners. The goal of the study described in this paper was to present evidence of the impact of online resources on such informal learners. In this study, the informal learners were a group of parents with young children aged between 0 and 6, and the knowledge being learned informally was that of their knowledge of and attitudes to their parenting skills. This study used an online parenting portal, KidzGrow Online, to identify if and how an online resource could impact on the group of parents with regard to the time they spent with their children, their own perceived level of knowledge of their children’s development, and the level of their self-confidence in their parenting role. The study showed that after a period of three months, significant differences could be observed between the responses from parents who had access to the online resource and those from parents who did not.

Student engagement in course-based social networks: The impact of instructor credibility and use of communication

Social network sites provide the opportunity for building and maintaining online social network groups around a specific interest. Despite the increasing use of social networks in higher education, little previous research has studied their impacts on student's engagement and on their perceived educational outcomes. This research investigates the impact of instructors' self-disclosure and use of humor via course-based social networks as well as their credibility, and the moderating impact of time spent in these course-based social networks, on the students' engagement in course-based social networks. The research provides a theoretical viewpoint, supported by empirical evidence, on the impact of students' engagement in course-based social networks on their perceived educational outcomes. The findings suggest that instructors who create course-based online social networks to communicate with their students can increase their engagement, motivation, and satisfaction. We conclude the paper by suggesting the theoretical implications for the study and by providing strategies for instructors to adjust their activities in order to succeed in improving their students' engagement and educational outcomes.

When changing the look of privacy policies affects user trust: An experimental study

The majority of Internet users do not read privacy policies because of their lengthy verbose format, although they are still the main source of information for users about how their data are collected and used. Consequently, as shown by many studies, users do not trust online services with respect to the use of their private data. Furthermore, they find it unfair that their data are used to generate revenue by online services without their knowledge or without their benefit from this.In this paper, we take as main assumption that the control of their private data and also caring about their interests would restore the trust of users. Based on an empirical model, we conducted an experimental comparative study of user trust by offering to two groups of participants the possibility to adhere to a service with a privacy policy presented in one of two different formats: the first, a conventional privacy policy and the second, designed according to the privacy policy model studied in this paper.We collected, through a survey, 717 responses from participants. The results show that allowing personalization and management in privacy policies affects user trust and makes online services appear more trustworthy to their users.     

Cooperation in the evolutionary iterated prisoner’s dilemma game with risk attitude adaptation

The Iterated Prisoner’s Dilemma (IPD) game has been commonly used to investigate the cooperation among competitors. However, most previous studies on the IPD focused solely on maximizing players’ average payoffs without considering their risk preferences. By introducing the concept of income stream risk into the IPD game, this paper presents a novel evolutionary IPD model with agents seeking to balance between average payoffs and risks with respect to their own risk attitudes. We build a new IPD model of multiple agents, in which agents interact with one another in the pair-wise IPD game while adapting their risk attitudes according to their received payoffs. Agents become more risk averse after their payoffs exceed their aspirations, or become more risk seeking after their payoffs fall short of their aspirations. The aspiration levels of agents are determined based on their historical self-payoff information or the payoff information of the agent population. Simulations are conducted to investigate the emergence of cooperation under these two comparison methods. Results indicate that agents can sustain a highly cooperative equilibrium when they consider only their own historical payoffs as aspirations (called historical comparison) in adjusting their risk attitudes. This holds true even for the IPD with a short game encounter, for which cooperation was previously demonstrated difficult. However, when agents evaluate their payoffs in comparison with the population average payoff (called social comparison), those agents with payoffs below the population average tend to be dissatisfied with the game outcomes. This dissatisfaction will induce more risk-seeking behavior of agents in the IPD game, which will constitute a strong deterrent to the emergence of mutual cooperation in the population.
