“Boomerang” employees are workers who leave an organization and are later rehired by that same organization. Although many organizations rehire former employees, only a handful of studies have examined this phenomenon. The present study uses a large, longitudinal data set to examine the performance and turnover of boomerang employees rehired into management positions (n = 1,318). Further, we provide some of the first comparisons between boomerang employees and two traditional sources of employees: external hires (n = 20,850) and internal promotions (n = 8,546). Evaluations of job performance before and after being rehired revealed that boomerang managers’ performance tended to remain the same—rather than increase or decrease—after being rehired. Furthermore, boomerang managers performed similarly to internally and externally hired managers in the first year on the job, but both internal and external hires improved more than rehires over time. Internal and external hires were also less likely to turn over from the organization than rehires. Finally, supplemental analyses indicated that boomerang managers who turned over a second time tended to do so for reasons similar to their initial turnover reasons. The overall results call into question some of the assumed benefits of rehiring and suggest that organizations consider factors such as the reason for initial departure, the time horizon of performance, and the availability of other types of hires before considering boomerang employees.

Objective The purpose of this study was to investigate the effect of vocal training on acoustic and aerodynamic characteristics of student actors’ voices. Study Design Prospective cohort study. Setting Tertiary medical facility speech and swallow center. Subjects and Methods Acoustic, aerodynamic, and Voice Handicap Index–10 measures were collected from 14 first-year graduate-level drama students before and after a standard vocal training program and analyzed for changes over time. Results Among the aerodynamic measures that were collected, mean expiratory airflow was significantly reduced after vocal training. Among the acoustic measures that were collected, mean fundamental frequency was significantly increased after vocal training. On average, Voice Handicap Index–10 scores were unchanged after vocal training. Conclusion The cohort of drama students undergoing vocal training demonstrated improvements in voice aerodynamics, which indicate enhanced glottal efficiency after training. The present study also found an increased average fundamental frequency among the actors during sustained voicing and no changes in jitter and shimmer despite frequent performance.

Although Korea has achieved striking economic success during last four decades, following the 1997-98 foreign exchange crisis, Korea's economy was in urgent need of restructuring amid a series of corporate bankruptcies and a paralyzing credit crunch. In this paper using an unpublished plant-level panel data set, I explore changes in total factor productivity and its growth before and after the crisis. In order to do so, I sort out eight industries that were most likely affected by the "Big Deal Program". The results suggest the Big Deal had a positive and significant effect on TFP levels. Bigger plants in Big Deal industries had differentially higher TFP levels However, these results are not robust to the bigger plants classified as being in the top 5% in terms of K/L ratio. Unlike the results for TFP levels, coefficient for the three variable interaction term ( DiTt[arrow][tau] Spt ) are all positive and significant with the plant-size specification. It means the bigger plants in eight Big Deal industries have more productivity growth even though they have lower TFP levels than the smaller plants after the reform. Depending on the plant-size specifications, the Big Deal program had a positive effect on the bigger plants in the Big Deal industries of 0.1 to 1.39 percents.

AbstractWe present a novel longitudinal multimodal corpus of physiological and behavioral data collected from direct clinical providers in a hospital workplace. We designed the study to investigate the use of off-the-shelf wearable and environmental sensors to understand individual-specific constructs such as job performance, interpersonal interaction, and well-being of hospital workers over time in their natural day-to-day job settings. We collected behavioral and physiological data from n = 212 participants through Internet-of-Things Bluetooth data hubs, wearable sensors (including a wristband, a biometrics-tracking garment, a smartphone, and an audio-feature recorder), together with a battery of surveys to assess personality traits, behavioral states, job performance, and well-being over time. Besides the default use of the data set, we envision several novel research opportunities and potential applications, including multi-modal and multi-task behavioral modeling, authentication through biometrics, and privacy-aware and privacy-preserving machine learning.

Abstract Genomic predictivity is expected to decay over time as predictions are evaluated to more distant generations. More data increases predictive ability; however, data from distant ancestors may not add a significant amount of value compared to the data from closely related individuals. The objective of this study was to evaluate the decay in genomic predictivity over time and to compare the magnitude of decay when including ancestral data versus data from 2 and 3 most recent generations for body weight at off-test (BW). The data set included 211,812 phenotypic records. The pedigree included 406,983 animals from 2001 to 2020, of which 55,118 were genotyped. A single-trait model was used with all ancestral data and sliding subsets of two- and three-generation intervals. Single-step GBLUP was used to calculate GEBVs. Predictive abilities were calculated by the correlation between GEBVs and adjusted phenotypes. Validation populations consisted of single generations succeeding the training population and continued for all generations available. Predictive ability was slightly higher, with all ancestral data in the training population compared to three- and two-generation intervals. The decay of predictivity was similar when comparing the three training population subsets. The average predictivity for the validation population immediately following the training population was 0.40 for 2016, 0.39 for 2017, 0.35 for 2018, and 0.29 for 2019. Predictive ability reached a maximum in the year 2017 (0.45) for the ancestral training population, 2017 (0.43) for the 3-year training population, and 2016 (0.38) for the 2-year training population. The average decay of predictive ability from the first year after the training population to the second year was -0.08. Realized predictivity is affected by selection pressure. The drop in predictive ability suggests declining heritability. With more data and with consistent selection pressure, predictive abilities should increase.

Mood improvement immediately after a single bout of exercise is well documented, but less is known about successive and longer term effects. In a “real-life” field investigation, four kinds of exercise class (Beginners, Advanced, Body Funk and Callanetics) met once a week for up to 7 weeks. Before and after each class the members assessed how they felt by completing a questionnaire listing equal numbers of “positive” and “negative” mood words. Subjects who had attended at least five times were included in the analysis, which led to groups consisting of 18, 20, 16, and 16 subjects, respectively. All four kinds of exercise significantly increased positive and decreased negative feelings, and this result was surprisingly consistent in successive weeks. However, exercise seemed to have a much greater effect on positive than on negative moods. The favorable moods induced by each class seemed to have worn off by the following week, to be reinstated by the class itself. In the Callanetics class, positive mood also improved significantly over time. The Callanetics class involved “slower,” more demanding exercises, not always done to music. The Callanetics and Advanced classes also showed significantly greater preexercise negative moods in the first three sessions. However, these differences disappeared following exercise. Possibly, these two groups had become more “tolerant” to the mood-enhancing effects of physical exercise; this may be in part have been due to “exercise addiction.”

Wing lengths of Clamorous Reed Warblers Acrocephalus stentoreus in Israel Wing length measurements taken from first-year, pre- and post-moulting (annual, complete) Clamorous Reed Warblers were recorded at a site in northern Israel. The resulting data set was examined using a time-series of residuals (CUSUM). Results from this analysis can explain the reported heterogeneity found in a comparable data set by Merom et al. (1999). Further observations made in their paper are rebutted: (1) an implied assumption that Reed Warbler (Acrocephalus scirpaceus) spring migration in Israel ends by 1 May is contrary to other publications; (2) the late autumn occurence in N Israel of longer-winged 1st cal. yr. Reed Warblers, unconvincingly explained as either delayed migration by larger individuals or post fledging feather growth, is most likely due to birds from different provenances origins moving at different seasons; (3) growth during adulthood in Reed Warbler is not a new discovery, though presented as such.

This paper empirically discovered the inter-linkages between stock and crude oil prices before and after the subprime financial crisis 2008 by using Johansan co-integration and Granger causality techniques to explore both long and short- run relationships.  The whole data set of Nifty index, Nifty energy index, BSE Sensex, BSE energy index and oil prices are divided into two periods; before crisis (from February 15, 2005 to December31, 2007) and after crisis (from January 1, 2008 to December 31, 2018) are collected and analyzed. The results discovered that there is one-way causal relationship from crude oil prices to Nifty index, Nifty energy index, BSE Sensex and BSE energy index but not other way around in both periods. However, a bidirectional causality relationship between BSE Energy index and crude oil prices during post subprime financial crisis 2008. The co-integration results suggested that the absence of long run relationship between crude oil prices and market indices of BSE Sensex, BSE energy index, Nifty index and Nifty energy index before and after subprime financial crisis 2008.

Do So

From 1996 to 1998, listed companies in China were required to achieve a minimum return on equity (ROE) of 10 percent in each of the previous three years before they could apply for permission to issue additional shares. As a result of this rule, there was a heavy concentration of ROEs in the area just above 10 percent. We show that the Chinese regulators appear to have scrutinized firms using excess amounts of nonoperating income to reach the 10 percent hurdle. In addition, their ability to do so seems to have improved over time, which allows them to be better able to identify firms that subsequently performed better. However, many firms were still able to gain rights issue approval through excess nonoperating income. We show that these firms subsequently underperformed other approved firms that did not use the same practice, indicating that the Chinese regulators' objective of guiding capital resources toward the well-performing sectors is partially compromised by earnings management.
