Construct Validity of a General Training Climate Scale

There is growing evidence that an organization\u27s training climate can influence the effectiveness of formal and informal training activities. Unfortunately, there is limited data regarding the psychometric properties of climate measures that have been used in training research. The purpose of this article is to examine the construct validity of a training climate measure. Results from content adequacy, reliability, aggregation, and convergent, discriminant, and criterion-related validity assessments provide support for the measure\u27s use in diagnostic and theory testing efforts

Helping Managers Help Themselves: The Use and Utility of On-the-Job Interventions to Improve the Impact of Interpersonal Skills Training

The purpose of this study was to examine the utility of using two posttraining interventions—self-coaching and upward feedback—to enhance the effectiveness of formal training on interpersonal skills for managers. Data from eighty-seven restaurant manager trainees demonstrated that both interventions were useful extensions to formal classroom training and appear to have substantial utility for helping managers develop and improve their interpersonal skills

In Favor of Hospitality-Management Education

Despite the almost one-hundred-year history of hospitality-management education; the hundreds of well-established two-year, four-year, and graduate programs worldwide; and the hundreds of thousands of graduates those programs have prepared for careers in the industry, hospitality-management education’s merit and place in higher education are still questioned at times, to the dismay of hospitality educators the world over. This article delineates several features of hospitality management that make these programs valuable and unique and provides compelling arguments in its favor. The arguments include: 1) courses tailored to the hospitality industry, the world’s largest industry; 2) focus on small-business management as well as corporate enterprises; 3) emphasis on services and service management, not manufacturing; 4) programs and coursework focused on people management, which it at the core of the hospitality businesses; 5) unique focus on the specific issues of food and beverage management, the largest component of the hospitality industry; and 6) transferability of graduates’ knowledge and skill sets, which are in high demand among other service industries. While business programs focus on the fundamentals of management and production, hospitality- management programs prepare graduates who are aware of general management principles and are particularly well-versed in managing the guest experience and employees in a service environment

What Matters Most? The Perceived Importance of Ability and Personality for Hiring Decisions

This study examined the emphasis hiring managers placed on general mental ability (GMA) and personality—agreeableness, conscientiousness, emotional stability, and extraversion—when evaluating applicant profiles for servers for a national restaurant chain. GMA was framed as either “intelligence” or the “ability to learn and solve problems.” Under both conditions, GMA was valued, but less than agreeableness, conscientiousness, and emotional stability, even though GMA has been demonstrated to be the strongest predictor of employee performance. Framed as the “ability to learn and solve problems,” GMA was more highly valued, but still less than personality

The Role of Personality and General Mental Ability in Predicting Performance for New and Experienced Employees

[Excerpt] Recently, the lead author took his family to a small, family-oriented water park in upstate New York. During the visit, a boy about 15 years old cut his foot while exiting one of the more popular attractions. His injury was fairly severe and required medical attention. The park staff responded promptly and professionally. First aid was rendered, and the injured guest and his family appeared to be quite satisfied with the care they were given. After the injured guest and his family had left, several employees stayed at the scene and cleaned up the area where the incident took place. As the employees were cleaning the area, they were approached by several park guests who asked what had happened. The employees continued to perform their cleaning duties but took the time to answer the questions that were asked. Their responses were accurate, reassuring, and seemed to satisfy everyone\u27s curiosity. As we left the park, we found the general manager, who was thanking all of the departing guests for coming to the park. We complimented him on his staff and their management of the situation. We explained that his employees appeared to have a firm grasp on the technical skills necessary to perform one of the primary functions of their jobs— adhering to safety and sanitation standards—as well as the ability to manage sensitive interactions with guests. The general manager thanked us, and then, without prompting, told us that he looks for employees who can do the basics first and then keep a smile on their face when things go wrong

Fun in the workplace : a review and expanded theoretical perspective

Since the turn of the century, a growing body of research has systemically examined the role of fun in the workplace. In general, the extant body of research has demonstrated that fun in the workplace has a beneficial impact for individuals and organizations, but some evidence has been mixed. To help advance research in this area, the aims of this paper are two-fold. The first aim is to review previous research on fun in the workplace and identify gaps in the literature to provide direction for future work. The second aim is to offer a theoretical framework that helps explain how individuals may interpret fun in the workplace and how it may be most beneficial. Drawing on the notion that fun in the workplace is in the eye of the beholder, our proposed framework provides a more nuanced understanding of the temporal processes and contextual factors that explain how individuals appraise and ultimately benefit from fun

Modeling Solids in Nuclear Astrophysics with Smoothed Particle Hydrodynamics

Smoothed Particle Hydrodynamics (SPH) is a frequently applied tool in computational astrophysics to solve the fluid dynamics equations governing the systems under study. For some problems, for example when involving asteroids and asteroid impacts, the additional inclusion of material strength is necessary in order to accurately describe the dynamics. In compact stars, that is white dwarfs and neutron stars, solid components are also present. Neutron stars have a solid crust which is the strongest material known in nature. However, their dynamical evolution, when modeled via SPH or other computational fluid dynamics codes, is usually described as a purely fluid dynamics problem. Here, we present the first 3D simulations of neutron-star crustal toroidal oscillations including material strength with the Los Alamos National Laboratory SPH code FleCSPH. In the first half of the paper, we present the numerical implementation of solid material modeling together with standard tests. The second half is on the simulation of crustal oscillations in the fundamental toroidal mode. Here, we dedicate a large fraction of the paper to approaches which can suppress numerical noise in the solid. If not minimized, the latter can dominate the crustal motion in the simulations.Comment: 24 pages, 29 figure

Kti12, a PSTK-like tRNA dependent ATPase essential for tRNA modification by Elongator

Posttranscriptional RNA modifications occur in all domains of life. Modifications of anticodon bases are of particular importance for ribosomal decoding and proteome homeostasis. The Elongator complex modifies uridines in the wobble position and is highly conserved in eukaryotes. Despite recent insights into Elongator's architecture, the structure and function of its regulatory factor Kti12 have remained elusive. Here, we present the crystal structure of Kti12's nucleotide hydrolase domain trapped in a transition state of ATP hydrolysis. The structure reveals striking similarities to an O-phosphoseryl-tRNA kinase involved in the selenocysteine pathway. Both proteins employ similar mechanisms of tRNA binding and show tRNASec-dependent ATPase activity. In addition, we demonstrate that Kti12 binds directly to Elongator and that ATP hydrolysis is crucial for Elongator to maintain proper tRNA anticodon modification levels in vivo. In summary, our data reveal a hitherto uncharacterized link between two translational control pathways that regulate selenocysteine incorporation and affect ribosomal tRNA selection via specific tRNA modifications.</p

Mechanism of age-dependent susceptibility and novel treatment strategy in glutaric acidemia type I

Glutaric acidemia type I (GA-I) is an inherited disorder of lysine and tryptophan metabolism presenting with striatal lesions anatomically and symptomatically similar to Huntington disease. Affected children commonly suffer acute brain injury in the context of a catabolic state associated with nonspecific illness. The mechanisms underlying injury and age-dependent susceptibility have been unknown, and lack of a diagnostic marker heralding brain injury has impeded intervention efforts. Using a mouse model of GA-I, we show that pathologic events began in the neuronal compartment while enhanced lysine accumulation in the immature brain allowed increased glutaric acid production resulting in age-dependent injury. Glutamate and GABA depletion correlated with brain glutaric acid accumulation and could be monitored in vivo by proton nuclear magnetic resonance (1H NMR) spectroscopy as a diagnostic marker. Blocking brain lysine uptake reduced glutaric acid levels and brain injury. These findings provide what we believe are new monitoring and treatment strategies that may translate for use in human GA-I

CD90 is dispensable for white and beige/brown adipocyte differentiation

Brown adipose tissue (BAT) is a thermogenic organ in rodents and humans. In mice, the transplantation of BAT has been successfully used to combat obesity and its comorbidities. While such beneficial properties of BAT are now evident, the developmental and cellular origins of brown, beige, and white adipocytes have remained only poorly understood, especially in humans. We recently discovered that CD90 is highly expressed in stromal cells isolated from human white adipose tissue (WAT) compared to BAT. Here, we studied whether CD90 interferes with brown or white adipogenesis or white adipocyte beiging. We applied flow cytometric sorting of human adipose tissue stromal cells (ASCs), a CRISPR/Cas9 knockout strategy in the human Simpson-Golabi-Behmel syndrome (SGBS) adipocyte model system, as well as a siRNA approach in human approaches supports the hypothesis that CD90 affects brown or white adipogenesis or white adipocyte beiging in humans. Taken together, our findings call the conclusions drawn from previous studies, which claimed a central role of CD90 in adipocyte differentiation, into question
