The Impact

The impact of chronic, intense exercise, such as in elite athletes, on phospholipids fatty acids (FA) composition has not been studied in women so far. This study aimed to investigate FA profiles in plasma and erythrocytes phospholipids in elite female water polo (N = 15) and football (N = 19) players in comparison with sedentary women. In spite of similar dietary patterns, as assessed by a food frequency questionnaire, plasma FA profile in the football players showed significantly higher proportions of stearic acid, oleic acid, and monounsaturated FA (MUFA), and significantly lower proportions of total and n-6 polyunsaturated FA (PUFA) than in the water polo and control group. The water polo players had higher percentages of palmitoleic acid and arachidonic acid than the control subjects. Erythrocyte FA profile differed among groups. We found significantly higher proportion of oleic acid and MUFA in the football group than in the controls, and decreased stearic acid and elevated palmitic and palmitoleic acid in the water polo players than in the other 2 groups. Both groups of athletes had significantly lower percentages of n-6 dihomo-γ-linolenic acid, n-6 PUFA, and total PUFA compared with the controls. The estimated activities of elongase and desaturases in erythrocytes were also altered in the athletes. Our results indicate that long-term, intense physical training significantly affects FA status of plasma and erythrocyte phospholipids in women. The observed differences between the water polo and the football players suggest that the type of regular training may contribute to the altered metabolism of FA, although possible genetic differences among the 3 study groups cannot be ruled out.

Abstract Background: There are drastic differences in smoking prevalence and control policies among different countries. However, the impact of international travels on passive smoking exposures and subsequent health effects remained unknown. Methods: We recruited 27 non-smokers who travelled from Los Angeles to Beijing for 10 weeks in 2014 and 2015. Urine samples (n=197) were collected before (LA-before), during (Beijing), and after (LA-after) the trip, for the assessment of biomarkers of passive smoking (cotinine), PAHs exposure (hydroxylated-PAHs), and lipid peroxidation (malondialdehyde and 8-isoprostane). Results: The geometric mean concentrations of urinary cotinine were 0.13, 1.50, and 0.22 µg/g creatinine in LA-before, Beijing, and LA-after, respectively. Likewise, hydroxylated-PAH levels were significantly higher in Beijing as compared to LA-before or LA-after (p<0.001), in association with the urinary cotinine concentrations (p<0.05). Traveling from Los Angeles to Beijing increased urinary concentrations of malondialdehyde by 51.8% (95%CI, 29.1% to 78.5%), which did not return to baseline levels, up to 4 - 10 weeks after traveling back to Los Angeles. Remarkably, while urinary 8-isoprostane concentrations were similar between Beijing and LA-before, those levels increased by 75.5% (95%CI, 48.5% to 108%) after returning to Los Angeles (LA-after), and were significantly higher than baseline (LA-before, 63.6%; 95%CI, 31.1% to 104%). Urinary concentrations of malondialdehyde and 8-isoprostane were positively associated with urinary cotinine concentrations, independently of hydroxylated-PAHs. Conclusion: Traveling from Los Angeles to Beijing increased exposures to passive smoking, which contributed to increased PAHs exposures and increased lipid peroxidation in the urine.Trial Registration: Not applicable.

This paper investigates how counterterrorism targeting terrorist leaders affects terrorist attacks. This effect is theoretically ambiguous and depends on whether terrorist groups are modeled as unitary actors or not. The paper exploits a natural experiment provided by strikes by Unmanned Aerial Vehicles (drones) “hitting” and “missing” terrorist leaders in Pakistan. Results suggest that terrorist groups increase the number of attacks they commit after a drone “hit” on their leader compared with after a “miss.” This increase is statistically significant for 3 out of 6 months after a hit, when it ranges between 47.7% and 70.3%. Additional analysis of heterogenous effects across groups and leaders, and the impact of drone hits on the type of attack, terrorist group infighting, and splintering, suggest that principal-agent problems—(new) terrorist leaders struggling to control and discipline their operatives—account for these results better than alternative theoretical explanations.

The Impact

Despite attempts to limit noise exposure, noise-induced hearing loss remains prevalent in the military. Both hearing loss and the noise itself can lead to communication issues which could negatively impact operational performance. This study builds upon a series of experiments examining the relationship between reduced speech intelligibility and performance in a naval command and control environment by equipping Navy watch standers with hearing loss simulators that control speech intelligibility in real time as they were engaged in a simulated operational scenario. This effort focused on the effects that a Sailor with impaired hearing might have on unimpaired shipmates and how the mission might specifically be impacted. Results showed that as speech intelligibility decreased for the impaired watch stander perceived workload increased in an unimpaired shipmate and the latency of the crew to respond to incoming missile threats and a direct order to kill an enemy ship increased significantly.

Maintenance Performance

Maintenance performance measurement aims to assess and improve the value created after maintenance efforts, as it determines the impact of maintenance on the performance of a system or facility and its business process. As objects of maintenance, prison facilities ought to provide a safe and decent environment for prison staff and prisoners to work and live in, as well as for all others who interact with the facilities. This study evaluates the satisfaction ratings of maintenance performance on prison facilities in Southwestern, Nigeria. A survey approach was adopted to collect data from the relevant Nigerian prison staff population of 2,187 prison workers, excluding staff in the maintenance unit within a specific period. Stratified sampling technique was used to generate a sample of 1,094, which is representative of the entire population across the prisons. Three hundred and eighty (35%) out of the one thousand and ninety-four copies of the questionnaire were completed and returned. Data collected were analysed using the SPSS package. The study found that prison staff showed satisfaction with the level of cleanliness in the prison environment, quality of water and control of ventilation employing a window, as well as partial satisfaction with the twenty-nine other criterion assessed. Overall, the study indicated partial satisfaction for performance on prison facilities and established a significant agreement among prison staff regarding the perception of the performance of prison facilities. The research, therefore, suggests continuous evaluation of maintained prison facilities to ascertain their condition and performance levels.

The purpose of this study was to discuss the impact of the extent of internationalization on firm performance measured for firms with a high Tobin’s Q (firms with good operating performance), a median Tobin’s Q (firms with average operating performance), and a low Tobin’s Q (firms with poor operating performance). In addition to discussion on the impact of internationalization on firm performance, this study also discussed the impact of corporate proprietary assets (using assets, R&D, marketing, and management-related variables as moderating variables) and control variables (scale of company, debt-asset ratio, firm age, board structure, and proportion of pledged shares by directors) on firm performance. The research results showed that there is an S-shaped relationship between extent of internationalization and firm performance. However, further discussion found that there is an S-shaped relationship between extent of internationalization and performance for firms with a high Tobin’s Q but a slight decline in the middle of the S-shaped curve, as well as a general linear negative correlation between extent of internationalization and performance for firms with a median Tobin’s Q and an inverted U-shaped correlation between extent of internationalization and performance for firms with a low Tobin’s Q.

The Impact

The intent of this research was to evaluate the effects of computerized mock examinations on student performances during the preparatory stage for a national board examination. Three measures were used: web-based surveys, student data from the ExamSim software (treatment group), and American Registry for Diagnostic Medical Sonography (ARDMS) examination scores. Three research questions were posed: (1) What are the differences in ARDMS scores between the treatment and control groups? Mean scores showed that the treatment group scored significantly higher than the control group on the ARDMS examination. (2) To what degree did the scores and time invested on the ExamSim software predict performance on the ARDMS examination? A multiple linear regression was conducted, and the result was significant, with time and software scores accounting for 37.6% of the variance in ARDMS scores. (3) How did utilizing a formative computer-based assessment change perceived testing anxiety levels during the test preparatory phase? The result of the dependent sample t test was significant. Self-perceived scores at posttreatment were lower than self-perceived scores at pretreatment.
