The Impact

The focus on quantifiable data in sport performance has led to incremental advantages in baseball and has played an important role in the development of new hitting, pitching, fielding, and coaching strategies. Recently, researchers and team representatives have considered the impact of additional factors in baseball, including cognitive functioning. In this study, predictive validity for the Athletic Intelligence Quotient (AIQ) was examined vis-à-vis performance outcomes in professional baseball. Specifically, AIQ scores were obtained from 149 Minor League Baseball (MiLB) players prior to the 2014 baseball season and their subsequent performance was assessed through traditional and newly emphasized baseball statistics. Using hierarchical multiple regression, it was demonstrated that the AIQ predicted statistically significant relationships with hitting and pitching statistics, after controlling for other variables. Given the recent impact of analytics in professional sports, the potential importance of the AIQ in the selection and coaching process was discussed.

The Impact

This paper examines whether and for how long managers’ initial assessments of employee ability influence promotion decisions. Using archival data from minor league professional baseball, we find that, controlling for performance, initial assessments are associated with promotion decisions for at least six years after the initial assessments were made. We also find that initial assessments are positively associated with future performance at the outset of a player’s career, but the association becomes insignificant after a player accumulates on-the-job experience. We show that the weight on initial assessments for promotion decisions declines as additional on-the-job performance signals are observed, reflecting the declining relative informativeness of initial assessments about future ability. We construct a proxy for relative informativeness based on coefficients from regressions of future performance on initial assessments and observed performance. When we compare the implied relative weight on initial assessments for promotion decisions to our proxy for relative informativeness, we find initial assessments receive greater relative weight than implied by informativeness overall and across experience and job-level partitions. Our results suggest managers update initial beliefs about worker ability slowly given available performance measures. This paper was accepted by Shiva Rajgopal, accounting.

Background: There has been minimal research investigating injury and pitching performance differences between Major League Baseball (MLB) and other professional leagues. Purpose/Hypothesis: This 2-team comparison between MLB and Japan’s Nippon Professional Baseball (NPB) involved affiliated players over 5 years. We hypothesized that teams would differ in the injury incidence, mechanism of injury, pitch velocity, and pitch type usage. Study Design: Descriptive epidemiology study. Methods: Between 2015 and 2019, pitching data as well as injury statistics for the highest level and minor league affiliates of the Los Angeles Angels (MLB) and the Hiroshima Toyo Carp (NPB) were reviewed for significant differences in the injury prevalence, injury type, mechanism of injury, and days missed. In total, 3781 MLB and 371 NPB injuries were studied. Results: MLB-affiliated players were significantly younger, taller, and heavier ( P < .001) than were NPB-affiliated players. MLB-affiliated pitchers threw faster than did their NPB counterparts ( P = .026). MLB minor league pitchers threw more curveballs than did NPB minor league pitchers ( P = .004), and MLB minor league relief pitchers threw more sliders than did NPB minor league relief pitchers ( P = .02). The MLB team had a 3.7-fold higher incidence of injuries versus the NPB team (0.030 vs 0.008 injuries per player-game, respectively) as well as more repeat injuries, with fewer days missed per injury (15.8 ± 54.7 vs 36.2 ± 55.1 days, respectively; P < .001). The MLB team also had a higher percentage of injuries that were throwing related ( P < .001), were contact related ( P < .001), and occurred outside of competition ( P < .001) compared with the NPB team. Conclusion: This is the first empirical study examining injury trends and pitching characteristics between MLB and NPB athletes. MLB-affiliated pitchers threw faster and relied more on breaking pitches in comparison with NPB-affiliated pitchers. From injury data, MLB players were younger, taller, and heavier with a higher percentage of throwing-related injuries, contact injuries, and injuries sustained outside of competition. Overall, the MLB team indicated a 3.7-fold higher rate of reported injuries with fewer days missed per injury than did the NPB team. Competitive conditions are distinctly different between MLB and NPB, and thus, more extensive research collaborations in the future can identify best practices to advance health and performance for both leagues.

Objectives: In the setting of ulnar collateral ligament (UCL) injury, surgical reconstruction of the UCL is not always selected, as it leads to a prolonged recovery time and return to play rates between 67-95%. To date, there is limited data on outcomes following nonoperative treatment in this population. Orthobiologics, such as platelet-rich plasma (PRP), have recently been used as an adjunct therapy for standard nonoperative treatment including rest and physical therapy for UCL injuries. The objective of this study was to determine if the addition of PRP injections in professional baseball players with UCL injuries reduces recovery time, lowers the likelihood of surgery, and increases the return to play rate compared to traditional nonoperative treatment. Methods: The Health and Injury Tracking System (HITS) database was searched from 2011-2015 for Major and Minor league baseball players with Grade I, II or III UCL injuries. Standard demographic, injury, and return to play data was obtained for all players. MRI’s for 353 athletes were reviewed by a musculoskeletal radiologist and graded accordingly. Outcomes were compared between players who received PRP injections in addition to traditional nonoperative treatment (PRP group) and players who received traditional nonoperative treatment alone (No PRP group). Statistical analysis was performed using Student’s T-test and Chi-square for parametric data. Kaplan Meier’s analysis was used for estimating longevity of the treatment. Results: A total of 544 Major and Minor League Baseball players with UCL tears underwent an initial course of nonoperative treatment (active rest & rehabilitation) for their injury between 2011-2015. Of these, 133 underwent PRP injections plus rehab and 411 underwent rehab alone. There was a significantly higher proportion of Major League Baseball players in the PRP group compared to the No PRP group (25.6% vs 9.0%, P<0.001). There was no difference between the two cohorts in regard to the grade of UCL tear (Figure 1). The players in the PRP group had a significantly longer time before returning to a throwing program compared to the No PRP group (64 days vs 51 days, P<0.001). The mean time from injury date to PRP injection was 14.5 days, which may explain the difference in time to return to throwing. The return to play rate in a live game without surgery was significantly lower in the PRP group compared to the No PRP group (46% vs 57%, P=0.03). There was no difference in the proportion of athletes requiring UCL reconstruction (58% vs 51%) or the time to surgery (154 days vs 178 days) between the two groups. Kaplan Meier survivor analysis showed no difference between the PRP and No PRP groups with regard to longevity of the native UCL (Figure 2). Conclusion: Among Major and Minor League Baseball players who were treated nonoperatively for a UCL injury between 2011-2015, 24% underwent PRP injections prior to rehab. Compared to traditional nonoperative rehab alone program, players who received PRP injections experienced a significantly longer time before returning to throwing, which may be in part due to the delay between the injury date and PRP injection. PRP injections did not appear to have a significant effect on the likelihood of surgical intervention.

Literature is increasingly recognizing that organizations must combine themes of care and concern with more established economic objectives. This conceptual study will expand on this literature by considering how expressions of organizational care toward employees, by improving their well-being, may influence their motivation, work involvement and, in turn, improve performance. In more detail, by extending the conceptual framework developed by Bonner & Sprinkle (2001), it is argued that managers should take into account the impact, not only of monetary and non-monetary incentives, but even of other caring policies, on employee motivation and performance outcomes. On this ground, this study develops a theoretical model on how organizational care may help employees in expressing their work potential and enhancing their performance. The model is developed within the health care context since its particular setting that strongly affects employees’ well-being.

Background: Numerous studies have investigated injuries and treatments in the baseball athlete. The majority of these studies have focused on the throwing shoulder and elbow. However, more recent literature is reporting injuries to other regions in this cohort, including the knee, head, hip, and hamstring. Purpose/Hypothesis: The purpose of the current study was to determine the number and type of injuries in Major League Baseball (MLB) and Minor League Baseball (MiLB) players that do not occur during the actual game but are related to baseball participation. Our hypothesis was that there would be a substantial number of injuries that occurred in professional baseball players during non-game situations. Study Design: Descriptive epidemiological study. Methods: Deidentified, anonymous data were collected from the 2011 through 2016 seasons from the MLB Health and Injury Tracking System (HITS) medical record database. All injuries that were identified as a primary diagnosis and resulted in at least 1 day out of play from both MLB and MiLB were examined. Injuries were categorized as occurring during the game (“game” injuries) or not during the game. A “non-game” injury was defined as occurring at any time other than during the scheduled game from the first to last pitch. Results: There were 51,548 total injuries in MLB and MiLB players from 2011 to 2016, almost 40% of which were attributed to non–game-related injuries (n = 19,201; 37.2%). The remainder occurred during a game (n = 32,347; 62.8%). A significantly greater percentage of non-game injuries were season ending (10.8%) compared with the percentage of game-related season-ending injuries (8.4%) ( P < .0001). Pitchers had significantly more non–game-related injuries than game-related injuries ( P < .0001). Conclusion: A large number of injuries occur in professional baseball outside of actual games. MiLB players, specifically pitchers, are particularly at risk for these types of injuries. It is feasible that the overall injury rate in professional baseball players could be reduced by analyzing these injuries in more detail to develop prevention strategies.

The Relationship

PurposeThe purpose of this study was to extend our knowledge of the relationship between quantitative and qualitative job insecurity and performance. On the basis of stress theories, we hypothesised that qualitative job insecurity (QLJI) would mediate the negative effect of quantitative job insecurity (QTJI) on two different indicators of performance: task performance (TP) and counterproductive work behaviours (CPWBs). In addition, the authors hypothesised that the effect of QTJI on QLJI would be moderated by the economic sector (public vs private) in which employees worked. Therefore, the authors empirically tested a moderated mediation model via PROCESS.Design/methodology/approachParticipants were 431 employees from various Italian organisations. Data were collected using a self-report questionnaire measuring QTJI, QLJI, TP and CPWBs.FindingsThe results indicated that economic sector moderated the relationship between quantitative and QLJI. Both quantitative and QLJI were related to performance outcomes. Furthermore, QLJI mediated the effect of QTJI on TP and CPWB. However, this mediation was particularly apparent among employees in the private sector, supporting our hypothesised moderated mediation model.Practical implicationsThe results suggest that managers of private and public organisations need to apply different policies to reduce the impact of job insecurity on CPWBs and increase the TP of their employees.Originality/valueThis study attempted to examine the job insecurity–performance relationship in more depth. For the first time, the effects of both job insecurity dimensions on performance were simultaneously investigated, with economic sector as a moderator and QLJI as a mediator.

In this paper several theories, which make different predictions about the effect of board leadership structure on firm performance, are tested. The results indicate that, for Australian listed companies, there is no strong relationship between leadership structure and subsequent performance. It is reported that companies with higher blockholder ownership or lower managerial shareholdings tend to have an affiliated chairman; firm with higher managerial shareholdings tend to have an executive chairman. The evidence suggests that there is no one optimal leadership structure; each structure, which could be an outcome of a rational choice process influenced by other governance characteristics of individual firms, may have associated costs and benefits.

Objective: Research was conducted to evaluate the correlation between design hypotheses and performance outcomes in single-occupancy patient rooms. Background: Health environments host complex interactions between patients and clinicians, and patient rooms offer a unique lens to understanding the impact of design on interactions and outcomes. This places importance on articulating, measuring, and assessing design hypotheses. This study of documented strategies and measured outcomes in patient room design investigates the relationship between design variables and clinical interactions. Methods: Design hypotheses were identified for the strategic approach to four key elements of patient room design: the room configuration, charting location, personal protective equipment (PPE) supply, and mobile supply cart. Researchers collected observational data from existing and newly constructed patient rooms in order to evaluate performance outcomes related to design hypotheses. Results: Observation data supported hypotheses behind three of the four design components and revealed greater insight into how design variables impacted interactions in patient rooms. Conclusions: The study identified a distinction between “fixed” design elements, such as the configuration of the patient room, and “dynamic” elements such as the design of the mobile cart. This was more prevalent in evaluating the use of supply carts and PPE cabinets, which may be more influenced by training, while the room configuration and charting location require little training to benefit both clinicians and patients. This study points to the value of research that evaluates correlations between design hypotheses and outcomes in healthcare design.

Background: Ankle and lower leg injuries are very common in sports, and numerous studies have discussed their diagnosis and management. Our study differs in that we report lower leg injuries in professional baseball players spanning the 2011-2016 seasons by utilizing a comprehensive injury surveillance system developed by Major League Baseball (MLB). Purpose: To determine the injury characteristics of ankle and lower leg injuries in professional baseball players during the 2011-2016 seasons by utilizing the MLB injury surveillance system. Study Design: Descriptive epidemiology study. Methods: Our study is a descriptive epidemiological evaluation through a retrospective review of injury data from the MLB Health and Injury Tracking System (HITS) since its implementation in 2010. We included any professional baseball player (MLB and Minor League Baseball [MiLB]) who was identified as having an ankle or lower leg injury between January 1, 2011, and February 28, 2017. Results: Over the study period, there were a total of 4756 injuries, of which 763 (16%) occurred in MLB players and 3993 (84%) occurred in MiLB players. The mean number of days missed for all players was 27.8 ± 141.4 days, with a median of 3 days. From 2011 through 2016, it was estimated that there were 414,912 athlete exposures (AEs) in MLB and 1,796,607 AEs in MiLB. Of the 4756 injuries recorded, 550 (12%) took place during the MLB regular season, and 3320 (70%) took place during the MiLB regular season. Injuries in MLB players, however, were 1.7 times more likely to require surgery ( P < .001). Additionally, rates of injury to the lower leg were stratified by position, with infield players experiencing injuries at a 1.6 times greater rate than any other position ( P < .001). Conclusion: In conclusion, this is the only epidemiological study to focus primarily on ankle and lower leg injuries in professional baseball players, utilizing an injury surveillance system developed by MLB.
