The Impact

E-sports are popular around the world and has become a full-time profession for an increasing number of players. Specialized keyboards, mice, headphones and gaming workstations have been developed to improve performance and reduce physical discomfort associated with prolonged gaming. Games have special requirements of operation requiring faster and larger movement, greater mouse sensitivity and higher input efficiency of pointing devices like the computer mouse. The rapid and precise movements of the mouse may impact performance and pose challenges to musculoskeletal health. Therefore, the purpose of this study was to compare muscle activity and performance while gaming with mice that vary in connection type (wired versus wireless) and weight (light versus heavy).

The Impact

Innovation is often the key to sustained progress, yet innovation itself is difficult and highly risky. Success is not guaranteed as breakthroughs are mixed with setbacks and the path of learning is typically far from smooth. How decision makers learn by trial and error and the efficacy of the process are inextricably linked to the incentives of the decision makers themselves and, in particular, to their tolerance for risk. In this paper, we develop a model of trial and error learning with risk averse agents who learn by observing the choices of earlier agents and the outcomes that are realized. We identify sufficient conditions for the existence of optimal actions. We show that behavior within each period varies in risk and performance and that a performance trap develops, such that low performing agents opt to not experiment and thus fail to gain the knowledge necessary to improve performance. We also show that the impact of risk reverberates across periods, leading, on average, to divergence in long-run performance across agents. (JEL D81, D83, O31, O38)

Anabolic Window

Nutrient timing involves manipulation of nutrient consumption at specific times in and around exercise bouts in an effort to improve performance, recovery, and adaptation. Its historical perspective centered on ingestion during exercise and grew to include pre- and post-training periods. As research continued, translational focus remained primarily on the impact and outcomes related to nutrient consumption during one specific time period to the exclusion of all others. Additionally, there seemed to be increasing emphasis on outcomes related to hypertrophy and strength at the expense of other potentially more impactful performance measures. As consumption of nutrients does not occur at only one time point in the day, the effect and impact of energy and macronutrient availability becomes an important consideration in determining timing of additional nutrients in and around training and competition. This further complicates the confining of the definition of “nutrient timing” to one very specific moment in time at the exclusion of all other time points. As such, this review suggests a new perspective built on evidence of the interconnectedness of nutrient impact and provides a pragmatic approach to help frame nutrient timing more inclusively. Using this approach, it is argued that the concept of nutrient timing is constrained by reliance on interpretation of an “anabolic window” and may be better viewed as a “garage door of opportunity” to positively impact performance, recovery, and athlete availability.

The Impact

Musicians spend long hours of practice and performance to master their instrument. Clarinet players support their roughly 2-lb instrument on the right-hand thumb, which results in cumulative static loading of the arm. This posture in turn can cause discomfort and, in some cases, evolve into debilitating overuse injuries and pain throughout the right upper limb. Altering the thumb-rest position has been proposed as a way to alleviate this discomfort, although no quantitative research has been conducted on this issue. The purpose of this study was to address the impact of thumb-rest position on the neuromuscular control of holding the clarinet. Surface electromyographic recordings of superficial muscles that control the right thumb, wrist, and arm were taken during realistic playing tasks. Twenty clarinetists performed 10 held notes and 10 exercises on the three different thumb-rest positions. The notes and exercises were chosen to isolate specific elements of playing. We hypothesized that a high thumb-rest position would result in a significantly different balance of muscle activity than traditional and low thumb-rest positions. The patterns of muscle activity recorded among clarinetists were idiosyncratic, but for all players these patterns were influenced by the note(s) played and thumb-rest position, and thus the hypothesis was partially supported. Muscles that acted on the thumb and wrist were most influenced by thumb-rest position. These results support the notion that adjustment of thumb-rest position may be a useful way to alleviate discomfort in the supporting limb but must be evaluated for each individual.

Subjective Trust

This study is part of an ongoing investigation into the ways in which individual differences may interact with game characteristics to impact performance and subjective trust outcomes within virtual environments. In this study, researchers investigated the impact of team leader agency on trust and performance. Forty college students were told they were working alongside a computer-programmed team leader or a human team leader who provided instructions for twelve tasks in a first-person shooter game, Arma 3™. Results indicate that team leader agency may not impact subjective trust using this type of experimental manipulation, but that intrinsic motivation is related to trust outcomes. Results also indicate differences in the number of times participants reviewed the team leader’s task instructions as a function of agency. Implications for future research include measuring trust behaviorally and investigating whether game-based intrinsic motivation may mediate the relation between trust and performance.

The Relationship

Intellectual capital (IC) has been proposed as an essential factor for organizational survival and maintenance of competitive strength. However, there has been very limited consensus on what encompasses IC and how it can best be conceptualized and measured. Further, very little empirical work has specifically examined the relationship between IC and financial performance. Given these shortcomings, this paper focuses first on the impact IC has on performance and secondly on the role strategic alliances may have on this relationship. While we argue that IC will impact performance, we anticipate this relationship will be moderated by strategic alliances and other inter-firm collaborations. Findings reveal interesting relationships that suggest further effort should be placed on the conceptualization and measurement of IC, specifically regarding its relationship to firm performance.

The Impact

The study was conducted to understand the effects of having access to different training materials in the interim between training and first use of an injection device for 27 injection-naïve participants. Participants were told they would be giving themselves a real injection of saline in the return session, and were not told that they would use injection pads until after subjective data was gathered during session 2. This deception paradigm was used to increase the external validity of the study. Participants self-trained in one of three conditions based on what they were given to take home: instructions for use, mechanical trainer, and/or a training video. Participants self-trained in session 1, performed a simulated injection in the session 2 two weeks later, and completed three online surveys in the interim. In session 2, a majority of participants were able to achieve minimally acceptable performance to deliver the medication during the simulated use of the autoinjector. Participants who took home a mechanical trainer had fewer use deviations than those who did not have the trainer at home. This difference was only seen in injection specific subtasks; performance on pre- and post-injection subtasks was low across all groups. Intermittent practice with a mechanical trainer was seen to improve performance on subtasks involved in the motor performance of the injection itself but did not impact performance or compliance with other tasks important to the injection. More holistic training solutions may be required to impact other aspects of the injection beyond the injection itself. While performance differed, subjective ratings did not differ, showing an overconfidence bias that may affect a user’s ability to self-report competence in device use.

Outstanding performance is a performance that follows systems according to planned criteria. However, in performance, it must have to have several standards so that efficiency increases so that the company usually runs according to what it wants. To improve employee performance, many factors have an immediate impact on it besides mastering technology and adapting to the global system. The goal of this research is to analyze the impact of competency variables and employee commitment to their performance at work. This study uses a cluster random sampling method with a total sample of 110 respondents. Retrieval of primary data through surveys with questionnaire instruments. In this study compensation indicators are direct and indirect, competency indicators namely: intellectual, emotional and social, indicators of organizational commitment namely affective commitment, commitment continuity, and normative commitment, and performance indicators namely: quality, quantity, timeliness, effectiveness, and independence. The results of this study are the positive and significant influence of competency variables and commitment to employee performance at work. There is a tendency that the two factors are the main factors in improving individual performance better. Significantly there will be an increase in performance if the competencies of employees further enhanced according to today's world technology. Another factor that should be considered is the knowledge factor that will make competence and commitment higher for the organization

Excessive working hours have negative consequences for employees’ health. Looking deeper into this problem, this article examines how employers’ needs for more intense working or more flexible working hours affect their employees’ psychosomatic health. A German representative survey of 13,452 full-time employees found that long working hours, work intensity (deadline and performance pressure) and flexibility requirements (permanent availability, changes in working hours) were significantly related to psychosomatic health complaints. When considering future work design and practices, these findings show which unfavourable working conditions are to be avoided to maintain the psychosomatic health of employees.

The Impact

Two studies were run to explore the relations between a conflict of competences (i.e., a situation in which two competent individuals present divergent solutions to the same task), counterfactual thinking, and performance. The first study shows that individuals who imagine themselves in a situation involving a conflict of competences generate more intensive subtractive than additive counterfactual thoughts. The second study tested the impact of a conflict of competences on performance in an anagram task. A condition involving a mere conflict of competences was compared to one involving a conflict of competences with additive counterfactuals (known to improve performance) and one involving a conflict of competences with subtractive counterfactuals (known to have no such effect on performance). As predicted, the performance of participants in the condition involving a mere conflict of competences and in that involving subtractive counterfactuals was inferior to that of participants in the condition involving additive counterfactuals.

Background The number of non-tenure-track faculty (NTTF), including both full-time (FT) and part-time (PT) positions, has risen to two-thirds of faculty positions across the academy. To date, most of the studies of NTTF have relied on secondary data or large-scale surveys. Few qualitative studies exist that examine the experience, working conditions, and worklife of NTTF. The study is framed by the theory advanced by Berger and Luckmann that reality is socially constructed and the broader sociological tradition of symbolic interactionism described by Blumer, Denzin, and Stryker. Purpose This study fills this gap in our current understanding by using qualitative methods to understand a fundamental issue that has not been examined and is critical to NTTF success and performance—how they perceive and experience support or lack of support within their work environments, particularly their departments. Participants I identified three four-year public institutions that are Master 1 according to the Carnegie Classification scheme. In total, I interviewed 107 NTTF, comprised of 58 PT and 49 FT, across the three institutions in 25 departments (14 unsupportive and 11 supportive). Research Design The study employed a multicase study approach using typical case sampling. The overall study examined departments that had made changes in policies and practices to support NTTF, compared to those that had not made changes, in order to investigate the impact on faculty performance and perspective. I conducted one-to-one interviews with NTTF as the main source of data collection. Findings The main findings of the study are that individual life conditions, such as career stage, and organizational features, such as the history of the department, shape the way NTTF construct support at any given time, and that this process of constructing support is dynamic and changing over a career. Conclusions The study suggests the importance of Shaker's hypothesized set of conditions that shape the perspective of NTTF. The study findings suggest that to understand the complex, multifaceted beliefs around support that are shaped by varying individual and institutional conditions, chairs might meet with the entire NTT faculty once a year in an open forum to discuss support or to anonymously survey all the faculty. NTTF leaders also need to be more aware of these differences in perceptions of support so they might better respond to needs.
