The current paper describes research that is aimed at elucidating our understanding of media technology factors that may help users of exercise equipment to stay motivated for doing regular workouts. In particular, we investigated the effects of immersion and coaching by a virtual agent on intrinsic motivation and the sense of presence of participants cycling on a stationary home exercise bike. A basic two-by-two within-subjects experimental design was employed whereby participants were presented with a virtual racetrack with two levels of immersion (high vs. low) and two levels of a virtual coach (with vs. without). Results indicate a clear positive effect of immersion on both motivation and presence. The virtual coach significantly lowered the perceived control and pressure/tension dimensions of intrinsic motivation, but did not affect the enjoyment dimension. The presence of the virtual coach also reduced negative effects associated with VEs, such as feeling dizzy or nauseated.

Corruption is a key factor that affects countries’ development, with emerging countries being a geographical area in which it tends to generate greater negative effects. However, few empirical studies analyze corruption from the point of view of disclosure by companies in this relevant geographical area. Based on a regression analysis using data from the 96 large companies from 15 emerging countries included in the 2016 International Transparency Report, this paper seeks to understand what determinants affect such disclosure. In that context, this paper provides empirical evidence to understand the factors that influence reporting on anti-corruption mechanisms in an area of high economic importance that has been little studied to date, pointing to the positive effect of press freedom in a country where the company is located and with the industry being the unique control variable that strengthens this relationship.

In a natural environment, plants usually interact with their neighbors predominantly through resource competition, allelopathy, and facilitation. The occurrence of the positive effect of allelopathy between peat mosses (Sphagnum L.) is rare, but it has been observed in a field experiment. It is unclear whether the stability of the water table level in peat induces positive vs. negative effects of allelopathy and how that is related to phenolic allelochemical production in Sphagnum. Based on field experiment data, we established a laboratory experiment with three neighborhood treatments to measure inter-specific interactions between Sphagnum angustifolium (Russ.) C. Jens and Sphagnum magellanicum Brid. We found that the two species were strongly suppressed by the allelopathic effects of each other. S. magellanicum allelopathically facilitated S. angustifolium in the field but inhibited it in the laboratory, and relative allelopathy intensity appeared to be positively related to the content of released phenolics. We conclude that the interaction type and intensity between plants are dependent on environmental conditions. The concentration of phenolics alone may not explain the type and relative intensity of allelopathy. Carefully designed combined field and laboratory experiments are necessary to reveal the mechanism of species interactions in natural communities.

Commitments to organizations and professions have important implications for behavior in the workplace, but little is known about how these dual commitments combine to affect organizational outcomes. We present a model proposing that commitment to professions influences productivity through a positive effect on intrinsic motivation and a negative effect on extrinsic motivation. Commitment to organizations, conversely, is hypothesized to have a negative effect on intrinsic motivation and a positive effect on extrinsic motivation. We tested the model with a sample of 237 tenured management professors and, overall, the model fit the data well and better than less parsimonious models or ones positing reverse causality. Commitment to the profession was positively related to intrinsic motivation to engage in research and, through this effect, resulted in more challenging research goals, increased commitment to those goals, more hours spent on research, and greater research productivity. Commitment to the organization (university) was positively related to extrinsic motivation and negatively related to intrinsic motivation and was unrelated to goal level, goal commitment, hours spent on research, and research productivity. Our model makes a unique theoretical contribution by revealing the differing paths by which commitments to organizations and professions affect work outcomes, and our results support and extend commitment theory and offer unique insights into posttenure productivity.

Purpose – In the last two decades, researchers have paid much attention to the role of cultural values on economic and social development. In particular, the crucial role of different aspects of culture on the development of innovation has been stressed in the literature. Consequently, it is vital to understand how social capital, as a core cultural value, affects the innovation process and the innovative performance at the national level. However, to date, the impact of different dimensions of social capital and innovation has not been properly portrayed or explained. Thus, the purpose of this paper is to investigate the influence of four different dimensions of social capital (institutional and interpersonal, associational life and norms) on two of the main functions of national innovation system (NIS) (entrepreneurship and knowledge creation) based on over 50,000 observations in 34 countries. Design/methodology/approach – In this regard, national-level data from the World Values Survey database was employed to quantify social capital. Entrepreneurship is, in turn, assumed to consist of three sub-indexes and 14 indicators based on the Global Entrepreneurship Index. Knowledge creation is also measured through US Patent Office applications. Also, exploratory factor analysis and structural equation modeling approach were used to build the measurement model and investigate the impact that each factor of social capital had on entrepreneurship and knowledge application, respectively. Measurement and structural models were built and their reliability and validity were tested using various fit indices. Research findings suggest the strong positive effect of institutional trust and networking on entrepreneurship. Also, interpersonal trust and networks were shown to have high influence on knowledge development at the national level. Norms appear to have naïve to medium negative effects on both functions. Findings – Research findings suggest the strong positive effect of institutional trust and networking on entrepreneurship.

In this research, self-healing due to further hydration of unhydrated cement particles is taken as an example for investigating the effects of capsules on the self-healing efficiency and mechanical properties of cementitious materials. The efficiency of supply of water by using capsules as a function of capsule dosages and sizes was determined numerically. By knowing the amount of water supplied via capsules, the efficiency of self-healing due to further hydration of unhydrated cement was quantified. In addition, the impact of capsules on mechanical properties was investigated numerically. The amount of released water increases with the dosage of capsules at different slops as the size of capsules varies. Concerning the best efficiency of self-healing, the optimizing size of capsules is 6.5 mm for capsule dosages of 3%, 5%, and 7%, respectively. Both elastic modulus and tensile strength of cementitious materials decrease with the increase of capsule. The decreasing tendency of tensile strength is larger than that of elastic modulus. However, it was found that the increase of positive effect (the capacity of inducing self-healing) of capsules is larger than that of negative effects (decreasing mechanical properties) when the dosage of capsules increases.

Competition is an apt place to experience intrinsic motivation, as competitive settings are often rich with optimal challenges and immediate, effectance-relevant feedback. Yet competition can also undermine intrinsic motivation and sustained engagement by introducing controlling pressures and negative feedback. To explain the contrasting effects of competitive settings on intrinsic motivation, this chapter presents a self-determination theory analysis. According to the theory, when elements of competitive settings are experienced as controlling or pressuring, they undermine competitors’ autonomy, decreasing intrinsic motivation. However, when these elements are perceived as both non-controlling and competence-informing, they can satisfy both autonomy and competence needs, enhancing intrinsic motivation. Unpacking these motivational crosscurrents, the authors identify the motivational implications of different elements of competition, including competitive set, pressure to win, feedback and competitive outcomes, challenge, leaders’ motivating styles, team interpersonal climate, and intrapersonal events such as ego-involvement. The authors also examine both positive and negative effects of competition on the need for relatedness. The chapter concludes by discussing how conditions that foster the need-satisfying aspects of competition not only enhance intrinsic motivation but also help prevent the emergence of competition’s darker sides, such as cheating, doping, objectifying opponents, aggression, and poor sportspersonship.

PurposeMedia literacy education is knowingly contributed to give insights in facilitating the interaction and communication, and thus enabling to understand the way we look at the world around us. However, the challenging issues emerged around need to take serious consent towards engaging the professional and ethical balance in the context of application strategy on media literacy education. This paper attempts to examine in addressing the ability with substantial foundation to recognize and understand between its benefit and its impacts assigned with analysing and evaluating the media engagement.Design/methodology/approachThis paper proposes the theoretical framework guideline with particular emphasis on empowering both professional and ethical dimensions relating to the media literacy and education to be keenly adhered to as a golden rule in media literacy, education and practice.FindingsThe findings reveal that such a marriage between the ethical dimensions and professional skills would promote the good of individuals, groups and broader society by addressing the inherent negative effects of media technology and practice. Consequently, the model would contribute to broader societal goodness and peaceful coexistence.Originality/valueThe professional and ethical balance being proposed here is necessary to reconsider the way and manner along with media technology tools utilized across different cultures with expressing the purpose of promoting appropriate and wise usage for the sustainable positive benefit of mankind at all times.

Industrial human-robot collaboration (HRC) is not yet widely spread but on the rise. This development raises the question about properties collaborative robots (cobots) need, to enable a pleasant and smooth interaction. Therefore, this study investigated the influence of transparency and reliability on perception of and trust towards cobots. A video-enhanced online study with 124 participants was conducted. Transparency was provided through the presentation of differing information, and reliability was manipulated through differing error rates. The results showed a positive effect of transparency on perceived safety and intelligence. Reliability had a positive effect on perceived intelligence, likeability and trust. The effect of reliability on trust was more pronounced for low transparent robots. The results indicate the relevance of carefully selected information to counteract negative effects of failures. Future research should transfer the study design into a real-life experiment with more fine-grained levels of transparency and reliability.
