This paper investigates the impact of having open 400 meter (400 m) runners on NCAA relay teams. Using data from 2012–2016 containing the top 100 4 × 400 m in each NCAA Division relay times for each year, it is found that more 400 m specialists lead to an increase in the overall performance of the team, measured by a decrease in relay times. The effect is examined across Division I–III NCAA track teams. The results are consistent across each division. We view this as a test of the role of specialization on performance. Using runners who specialize in 400 m races should increase overall team performance as long as specialization does not lead to an inefficient allocation of team human capital. An additional performance measure is used examining the difference between projected and actual relay times. Divisions I and II are found to perform better than projected with an increase in 400 m runners, but there is no effect found in Division III.

A great deal of research has been devoted to understanding the organizational returns of employee referral programs, particularly with respect to outcomes involving those hired through the referral process. Yet, no work has addressed whether the presence of a referral hire (i.e., the referred candidate who is hired and working in the firm) is related to behavioral outcomes for the referrer. Drawing on the social enrichment perspective, we theorize how referral hire presence (RHP), which is the time during which the referrer’s and the referral hire’s employment spells overlap, impacts referrer behavior. Using data from 265 referrers in a U.S. call center, we found that RHP was negatively related to referrer voluntary turnover and positively related to referrer job performance. Further, results from a supplemental experimental study supported our social enrichment rationale for the field study relationships, as the construct was associated with both RHP and additional attitudes known to be proximal predictors of turnover and performance. We also explore boundary conditions for the RHP effect in the call center data, revealing a nuanced mix of moderators of RHP effects. Overall, our findings provide the first evidence for the role of social enrichment, possible modifications to the well-established social enrichment perspective in the workplace, and evidence that understanding the impact of referral hiring necessitates careful consideration of the behavioral consequences for the referrer.

Abstract Agri-food systems include branching ramifications, which connect in the upstream the input suppliers with farmers, and downstream farmers, processors, retailers and consumers. In the last decades, at the level of the regions, food systems have undergone rapid transformation as a result of technological progress. The paper analyzes the changes made to the structure, behavior and performance of the agri-food system and the impact on farmers and consumers. Also, the role of agricultural research as a determinant factor of transformation of agri-food system is analyzed. The research objective is to develop technologies that cover the entire food chain (from farm to fork) and meet the specific requirements of consumers (from fork to farm) through scientific solutions in line with the principles of sustainable agriculture and ensuring the safety and food safety of the population.

Pupil with Obsessive-Compulsive Disorder. Over the past twenty years childhood OCD has received more attention than any other anxiety disorder that occurs in the childhood. The increasing interest and research in this area have led to increasing number of diagnoses of OCD in children and adolescents, which affects both specialists and teachers. Depending on the severity of symptoms OCD has a detrimental effect upon child's school performance, which can lead almost to the impossibility to concentrate on school and associated duties. This article is devoted to the obsessive-compulsive disorder and its specifics in children, focusing on the impact of this disorder on behaviour, experience and performance of the child in the school environment. It mentions how important is the role of the teacher in whose class the pupil with this diagnosis is and it points out that it is necessary to increase teachers' competence to identify children with OCD symptoms, to take the disease into the account, to adapt the course of teaching and to introduce such measures that could help children reduce the anxiety and maintain (or increase) the school performance within and in accordance with the school regulations and curriculum.

Internal control plays a role in risk prevention for firms when dealing with serious emergencies, which ensures the sustainable development of firms during a crisis. Based on the rapid outbreak of COVID-19 in China, this paper empirically tests whether internal control alleviates the negative impact of the pandemic on firm performance. Using a sample of Chinese listed firms from the first quarter of 2019 to the third quarter of 2020 and employing the difference-in-difference (DID) method, we find that the firms with a higher quality of internal control achieve better financial performance during the pandemic period; the more serious the pandemic is, the more obvious effect internal control plays. Furthermore, we consider the industry heterogeneity and firm heterogeneity of the risk resistance effect of internal control. In the manufacturing industry, which is a “disaster zone” of the pandemic, and the non-high-tech industry with a low degree of digitization, internal control can play a more important role in firms’ performance. Moreover, for state-owned enterprises, and firms with strong financing constraints, the role of internal control is more prominent. The above results provide empirical evidence for the risk prevention function of internal control and shed new light on the measures for firms to resist emergencies in the future.

The urban fabric of the desert cities is based on the principle of reducing the impact of urban canyons on direct solar radiation. Here comes this research, which is based on a comparative study of the periods of direct solarisation and values of the solar energy of urban canyons via two urban fabrics that have different building densities, where the ratio between L/W is different. In order to obtain the real values of the solar energy (thermal, lighting), the test field was examined every two hours, each three consecutive days. The measurement stations are positioned by the three types of the relationship between L/W, (L≥2w, L=w, L≤0.5w). According to the results, we noticed and recorded the difference in the periods of direct solarization between the types of urban engineering canyons, reaching 6 hours a day, the difference in thermal values of air, reaching 4 °C, and the difference in periods of direct natural lighting, reaching 6 hours. It should be noted that the role of the relationship between L/W is to protect the urban canyons by reducing the impact of direct solar radiation on urban canyons, providing longer hours of shading, and reducing solar energy levels (thermal, lighting) at the urban canyons. This research is classified under the research axis (the studies of external spaces in the urban environment according to the bioclimatic approach and geographic approach). But this research aims to focus on the tracking and studying the distribution of the solar radiation - thermal radiation and lighting radiation - in different types of street canyons by comparing the study of the direct solarization periods of each type and the quantity of solar energy collected during the solarization periods.

New York City launched a restaurant sanitation letter grade system in 2010. We evaluate the impact of customer loyalty on restaurant revisit intentions after exposure to a sanitation grade alone, and after exposure to a sanitation grade plus narrative information about sanitation violations (e.g., presence of rats). We use a 2 (loyalty: high or low) × 4 (sanitation grade: A, B, C, or pending) between-subjects full factorial design to test the hypotheses using data from 547 participants recruited from Amazon MTurk who reside in the New York City area. Our study yields three findings. First, loyal customers exhibit higher intentions to revisit restaurants than non-loyal customers, regardless of sanitation letter grades. Second, the difference in revisit intentions between loyal and non-loyal customers is higher when sanitation grades are poorer. Finally, loyal customers are less sensitive to narrative information about sanitation violations.

Self-affirmation produces large effects: Even a simple reminder of one’s core values reduces defensiveness against threatening information. But how, exactly, does self-affirmation work? We explored this question by examining the impact of self-affirmation on neurophysiological responses to threatening events. We hypothesized that because self-affirmation increases openness to threat and enhances approachability of unfavorable feedback, it should augment attention and emotional receptivity to performance errors. We further hypothesized that this augmentation could be assessed directly, at the level of the brain. We measured self-affirmed and nonaffirmed participants’ electrophysiological responses to making errors on a task. As we anticipated, self-affirmation elicited greater error responsiveness than did nonaffirmation, as indexed by the error-related negativity, a neural signal of error monitoring. Self-affirmed participants also performed better on the task than did nonaffirmed participants. We offer novel brain evidence that self-affirmation increases openness to threat and discuss the role of error detection in the link between self-affirmation and performance.

Purpose Library impact and how to evaluate it has been debated for a number of years. While the activity – the busy-ness – of the library is now routinely measured and described, the difference the library makes is less tangible and harder to measure. Libraries in all sectors and worldwide are grappling with this issue, and the purpose of this paper is to summarise international standards available to support them. Design/methodology/approach The first international standard concerning library impact, ISO 16439 Information and documentation – methods and procedures for assessing the impact of libraries, was published in 2014 after several years in development. Findings The standard describes a range of methods for assessing library impact which have been used across the world in a variety of libraries in all sectors. Originality/value This paper summarises the key methods described in the standard, and gives references for further reading.

Purpose This study aims at providing empirical evidence pertaining to the interaction among authentic leadership, workplace harmony, worker's creativity and performance in the context of telecommunication sector. These research streams remain important issues and of interest as the world continues to migrate toward a knowledge-based economy. Design/methodology/approach Applying structural equation modeling, this study diagnosed the impact of Authentic leadership (AL) on employees (n = 345) in two Jordanian telecommunication firms, specifically, how it shapes workplace climate, creativity and job performance. The study also tests the moderating role of knowledge sharing in the model, as well as the mediating role of workplace climate on the relationship between AL and positive organizational outcomes. Findings The empirical result suggests that AL positively influences workplace climate, creativity and job performance; workplace climate positively influences creativity and job performance; workplace climate mediates the relationship between AL and creativity, and job performance; and knowledge sharing behavior moderates the relationship between AL and workplace climate. Originality/value This study highlights the magnificent power of AL and knowledge sharing, not only in shaping the workplace atmosphere but also in delineating how these variables stimulate creativity and performance among employees. The implications for research and practice are discussed.

<p>This review comments upon the article entitled above. The article is well written and describes an interesting and original study. This review critiques the Method and Discussion sections of the article and offers suggestions for future research. Three specific points from the method are considered relating to: dual roles as researcher-musicians, the use of reflective diaries in research, and the impact on the research of the prior relationship between the authors. The unique role of &ldquo;written empathy&rdquo; is discussed within the context of empathic relationships. Also, this review considers how shifts from verbal to non-verbal communication may indicate movement from a &ldquo;top-down&rdquo; to &ldquo;bottom up&rdquo; response, and how this shift is related to &ldquo;empathetic attunement.&rdquo;</p>
