BackgroundThere are limited sensitive evaluation methods to distinguish people’s symptoms of peripheral fatigue and central fatigue simultaneously. The purpose of this study is to identify and evaluate them after acute exercise with a simple and practical scale.MethodsThe initial scale was built through a literature review, experts and athlete population survey, and a small sample pre-survey. Randomly selected 1,506 students were evaluated with the initial scale after exercise. Subjective fatigue self-assessments were completed at the same time.ResultsThe Acute Exercise-Induced Fatigue Scale was (...) determined after performing a factor analysis. In the exploratory factor analysis, the cumulative variance contribution rate was 65.464%. The factor loadings of the total 8 questions were 0.661–0.816. In the confirmatory factor analysis, χ2/df = 2.529, GFI = 0.985, AGFI = 0.967, NFI = 0.982, IFI = 0.989, CFI = 0.989, and RMSEA = 0.048. The Cronbach’s alpha coefficient for the scale was 0.872, and it was 0.833 for peripheral fatigue and 0.818 for central fatigue. The intra-class correlation coefficient for the scale was 0.536, and the intra-class correlation coefficients for peripheral fatigue and central fatigue were 0.421 and 0.548, respectively. The correlation coefficient between the total score of the AEIFS and the SFSA score was 0.592.ConclusionOur results demonstrate that the AEIFS can distinguish peripheral fatigue and central fatigue and can also reflect their correlation. This scale can be a useful evaluation tool not only for measuring fatigue after acute exercise but also for guiding reasonable exercise, choosing objective testing indicators, and preventing sports injuries resulting from acute exercise-induced fatigue.

We investigate the effectiveness of corporate social responsibility disclosure in protecting corporate reputation following financial restatements. As expected under legitimacy theory, firms can signal their legitimacy via nonfinancial disclosure after the negative effects of financial restatements. Our results show that restating firms make substantial improvements to overall CSR disclosure quality by changing their standalone reports to a more conservative tone, increasing readability and report length, even though they strategically disclose less forward-looking and sustainability-related content. Such improvements are more pronounced in (...) restating firms with prior low-quality CSR disclosure. Moreover, restating firms with CSR disclosure have smaller forecast errors than non-CSR disclosers, yet the change in CSR disclosure after restatements does not further improve analyst forecast accuracy. Finally, we find that compared with nondisclosers, restating firms with CSR disclosure suffer smaller firm value losses. Overall, the evidence supports the view that consistent CSR reporting alleviates reputational damage and plays an insurance-like or value protection role during crisis periods. (shrink)

Corporate citizenship represents various organizational activities and status related to the organization's societal and stakeholder obligations. This study develops five different dimensions of corporate citizenship and examines the relationship between the five dimensions and purchase intention by including two key mediators. In the proposed model of this study, purchase intention is indirectly affected by economic, legal, ethical, general philanthropic, and strategic philanthropic citizenship via the mediation of corporate identification and brand trust. Empirical testing using a survey of 353 consumers from (...) various industries confirms most of our hypothesized effects. Last, managerial implications for corporate leaders and limitations of our findings are discussed in depth. (shrink)

This study examines the impact of chief executive officer ability on firms’ corporate social responsibility performance. We find that firms’ CSR performance increases with CEO ability. Specifically, firms with more able CEOs are associated with more socially responsible activities and fewer socially irresponsible activities, and are associated with more stakeholder CSR rather than third-party CSR. We further find that the positive relation between CEO ability and CSR is weakened for CEO who is also the chair of the board and for (...) CEO who is close to retirement; and is weakened when the CSR emphasis exerted by a firm’s external environment is high. Our results are robust after controlling for firm fixed effects and to the use of multiple measures of CSR performance and CEO ability. Overall, our evidence is consistent with our conjecture that more able CEOs have less career concerns so that these CEOs are more willing to undertake long-term investments in socially beneficial activities, leading to better CSR performance.

Global climate change arouses people’s attention to environmental protection and, therefore, changes consumption habits. Food overconsumption not only produces extra waste but also pollutes the environment. Therefore, it is important to understand the factors that motivate people to eat green, an eco-friendly way to consume food. To keep the body in good shape, the fitnessers concern more about diet than the general people. This study explored intrinsic motivations, such as social recognition, environmental ethics, curiosity, joy of purchase, perceived usefulness, subjective (...) norm, and perceived behavior control as constructs that affect fitnesser’s green eating intention. All constructs except curiosity have significant impacts on behavior intention. The results demonstrate that social recognition and environmental ethics have significant effects on curiosity, joy of purchase, perceived usefulness, subjective norm, and perceived behavior control. The mediation effects between social recognition and behavior intention are not supported. The mediators between environmental ethics and behavior intention are joy of purchase, perceived usefulness, subjective norm, and perceived behavior control. (shrink)

This study examines the relation between a firm’s business strategy and its corporate social responsibility performance. Using a comprehensive measure of business strategy based on the Miles and Snow theoretical framework, we find that firms following an innovation-oriented strategy are associated with better CSR performance than those following an efficiency-oriented strategy. Specifically, compared with defenders, prospectors engage in more socially responsible activities, fewer socially irresponsible activities, and perform better in both stakeholder- and third-party-related CSR areas. Taken together, our results suggest (...) that business strategy is an important determinant of CSR performance. Prospectors take advantage of CSR, as their innovation-oriented strategy allows them not only to benefit more from CSR, but also to have more tolerance for the uncertainty, risk, and long time-horizon associated with CSR engagement.

Hydromechanical continuously variable transmission is capable of bearing large torque and has wide transmission range, which is suitable for high-power tractors. Dynamic characteristics could influence the tractor life, especially in a high-power tractor. Wet clutch is the crucial component in the HMCVT, which could smooth and soft power transmission. Therefore, it is important to study the dynamic characteristics and implement the wet clutch test of HMCVT. In this paper, AMESim is used to establish virtual models of gearbox, pump-controlled hydraulic motor (...) system, and shifting hydraulic system. Then, a simulation study of tractor operation under working condition is carried out. The internal and external meshing forces of the planetary row are analyzed. Finally, the wet clutch engagement process of HMCVT in the high-power tractor is tested to verify the oil pressure. The simulation results show that the values of internal and external meshing force become larger as the throttle opening increases. At the moment of shifting change, the meshing forces of the planetary gear have great impact. The clutch test shows that the trend of the oil filling curve obtained from the bench test is similar to that obtained from the theoretical curve, which verifies the simulation results. (shrink)

Although considerable research indicates that mental energy is an important factor in many domains, including athletic performance (Cook & Davis, 2006), athletic mental energy (AME) has never been conceptualized and measured. Therefore, the aim of this study was to conceptualize and develop a reliable and valid instrument to assess athletic mental energy. In Study 1, a focus group interview established the initial framework of athletic mental energy. Study 2 used a survey to collect athletes’ experiences of athletic mental energy and (...) develop a scale draft titled “Athletic Mental Energy Scale (AMES).” In Study 3, we examined the psychometric properties and the underlying structure of AMES via item analysis, internal consistency, and exploratory factor analysis (EFA). In Study 4, we used confirmatory factor analysis (CFA) to examine AMES’s factorial validity; and examined concurrent and discriminant validity by examining correlations with athletes’ life stress, positive state of mind, and burnout. In study 5, we examined the measurement invariance of the 6-factor, 18-item AMES with Taiwanese and Malaysian samples. Study 6 examined the predictive validity by comparing AMES scores of successful and unsuccessful martial artists. Across these phases, results showed a 6-factor, 18-item AMES had adequate content validity, factorial structure, nomological validity, discriminant validity, predictive validity, measurement invariance, and reliability. We suggest future studies may use AMES to examine its relationships with athletes’ cognition, affect, and performance. The application of AMES in sport psychology was also discussed. (shrink)

Drawing on propositions from the signaling theory and expectancy theory, this study hypothesizes that the perceived corporate citizenship of job seekers positively affects a firm’s attractiveness and career success expectation. This study’s proposed research hypotheses are empirically tested using a survey of graduating MBA students seeking a job. The empirical findings show that a firm’s corporate citizenship provides a competitive advantage in attracting job seekers and fostering optimistic career success expectation. Such findings substantially complement the growing literature arguing that corporate (...) citizenship brings firms competitive advantages without solid evidence from the perspective of recruitment and human resources.

Creative association is inherent and essential to creativity and insight. Here we utilised a Chinese compound Remote Associates Task (cRAT) to identify the potential impact of word order (i.e., solution position hereinafter) and word frequency on creative association across two behavioural experiments. Experiment 1 identified the effects of (a) word order and word frequency on cRAT-induced association without considering the specific strategies used during solving such problems and (b) their interaction not only on performance in solving the cRAT, including solution (...) time and accuracy, but also on difficulty rating. Following a coarse-to-fine approach, Experiment 2 examined the effect of both factors on creative association determined according to each participant’s trial-by-trial reports regarding insight solution strategies. Main effects of word order and word frequency, and a two-way interaction, were found on the accuracy and self-rated difficulty. These findings shed light on creative association, multiply-constrained problem solving and constructing compounds. (shrink)

ObjectiveTo explore the relationships between dispositional mindfulness and their post-traumatic stress symptoms of emergency nurses, and the mediating effects of coping styles and emotional exhaustion.MethodsA cross-sectional survey study was conducted to collect data on DM, coping styles, EE, and PTSS among 571 emergency nurses from 20 hospitals in Chongqing, China. Correlation and structural equation models were used to evaluate the relationship among variables.ResultsEmergency nurses with lower dispositional mindfulness, higher emotional exhaustion and preference for negative coping revealed more PTSS. The effect (...) of NC on PTSS was partially mediated by emotional exhaustion. Negative coping and emotional exhaustion played concurrent and sequential mediating roles between dispositional mindfulness and PTSS.ConclusionThis study has made a significant contribution to existing literature. It was suggested to develop interventions aimed at enhancing mindfulness, reducing negative coping strategies, and alleviating emotional exhaustion, which may be effective at reducing or alleviating post-traumatic stress symptoms of emergency nurses.

The COVID-19 pandemic has caused a dramatic reshaping of passenger risk perception for airline industry. The sharp increase in risk aversion by air passenger has caused a disastrous impact on the tourism service industry, particularly airline industry. Although the existing literature has provided a lot of studies on the impact of the pandemic on travel industry, there are very few studies discussing the impact of change in passenger risk perception on the stock market performance of airline industry. This study considers (...) two types of airline companies, full-service and low-cost. In order to overcome the traditional problem of the Chow test, Quandt–Andrews test is used to identify structural change points during the pandemic in the stock prices of United States airline companies. The result shows that an industry-wide structural change in the stock market performance indeed is found to take place during the pandemic for United States airline companies. Meanwhile, no significant difference is found in the structural change date between the two types of airline companies. The selected airline companies are found to be clustered toward the end of 2020 in their structural change dates. Although the strike of the COVID-19 pandemic on airline industry has proven to be widespread and profound, our investigation implies that air passengers have gradually adapted to the new normal of travel activities at some level and partly rebuild their sense of safety under the strict epidemic-control measures.

Background Individual physicians and physician-associated factors may influence patients’/surrogates’ autonomous decision-making, thus influencing the practice of do-not-resuscitate orders. The objective of this study was to examine the influence of individual attending physicians on signing a DNR order. Methods This study was conducted in closed model, surgical intensive care units in a university-affiliated teaching hospital located in Northern Taiwan. The medical records of patients, admitted to the surgical intensive care units for the first time between June 1, 2011 and December 31, (...) 2013 were reviewed and data collected. We used Kaplan–Meier survival curves with log-rank test and multivariate Cox proportional hazards models to compare the time from surgical intensive care unit admission to do-not-resuscitate orders written for patients for each individual physician. The outcome variable was the time from surgical ICU admission to signing a DNR order. Results We found that each individual attending physician’s likelihood of signing do-not-resuscitate orders for their patients was significantly different from each other. Some attending physicians were more likely to write do-not-resuscitate orders for their patients, and other attending physicians were less likely to do so. Conclusion Our study reported that individual attending physicians had influence on patients’/surrogates’ do-not-resuscitate decision-making. Future studies may be focused on examining the reasons associated with the difference of each individual physician in the likelihood of signing a do-not-resuscitate order. (shrink)

Previous studies have demonstrated that orientation-specific deprivation in early life can lead to neural deficits of spatial vision in certain space, and can even result in meridional amblyopia. Individuals with astigmatism are the optimal and natural models for exploring this asymmetric development of spatial vision in the human visual system. This study aims to assess the contrast sensitivity function and EEG signals along two principal meridians in participants with regular astigmatism when being optimal optical corrected. Twelve participants with astigmatism and (...) thirteen participants with were recruited in the current study. CSFs and spatial sweep visual evoked potentials were measured with vertical and horizontal sinewave gratings along two principal meridians monocularly. Area under log CSF, spatial frequency threshold corresponding to 80% contrast gratings, and CSF acuity were calculated from CSF test. In addition, sVEP amplitudes and thresholds were calculated with the recursive least square method. Participants with astigmatism exhibited marked vertical-horizontal resolution disparities even after they were corrected with optimal optical corrections. CSF tests showed that AULCSF along weak meridian was lower than that along strong meridian in both groups. Significant meridional disparity of CSF acuity was also found in both groups. In addition, the MA group showed larger meridional disparity compared to the AST group. Spatial sVEP thresholds also supported the existence of marked meridional disparity. Our results suggest that meridian-specific partial deprivation in early life might lead to monocularly asymmetric development of spatial vision in the human visual system. In terms of application, we tested the feasibility and reliability of adopting psychophysical and EEG scalings to investigate the asymmetric development of spatial vision related to astigmatism. These paradigms are potentially applicable to reduce and even eliminate the meridional disparity in the primary visual cortex by adopting perceptual learning or other vision-related interventions.

BackgroundThe neural activity of irritable bowel syndrome patients in the resting state without any intervention has not been systematically studied. The purpose of this study was to compare the resting-state brain functions of IBS patients with healthy controls.MethodsThe published neuroimage studies were obtained from electronic databases including PubMed, EMBASE, PsycINFO, Web of Science Core, CNKI Database, Wanfang Database, VIP Database, and CBMdisc. Search dates were from inception to March 14th, 2022. The studies were identified by the preidentified inclusion and exclusion (...) criteria. Two independent reviewers compiled the studies and evaluated them for quality and bias.ResultsAltogether 22 fMRI studies were included in this review. The risk of bias of the included studies was generally low. The findings indicated that in IBS patients, increased or decreased brain areas were mostly associated with visceral sensations, emotional processing, and pain processing. According to brain network research, IBS may exhibit anomalies in the DMN, CEN, and emotional arousal networks. The fluctuations in emotion and symptoms in IBS patients were associated with alterations in the relevant brain regions.ConclusionThis study draws a preliminary conclusion that there are insufficient data to accurately distinguish the different neurological features of IBS in the resting state. Additional high-quality research undertaken by diverse geographic regions and teams is required to reach reliable results regarding resting-state changed brain regions in IBS. (shrink)

Image restoration is a research hotspot in computer vision and computer graphics. It uses the effective information in the image to fill in the information of the designated damaged area. This has high application value in environmental design, film and television special effects production, old photo restoration, and removal of text or obstacles in images. In traditional sparse representation image restoration algorithms, the size of dictionary atoms is often fixed. When repairing the texture area, the dictionary atom will be too (...) large to cause blurring. When repairing a smooth area, the dictionary atom is too small to cause the extension of the area, which affects the image repair effect. In this paper, the structural sparsity of the block to be repaired is used to adjust the repair priority. By analyzing the structure information of the repair block located in different regions such as texture, edge, and smoothing, the size of the dictionary atom is adaptively determined. This paper proposes a color image restoration method that adaptively determines the size of dictionary atoms and discusses a model based on the partial differential equation restoration method. Through simulation experiments combined with subjective and objective standards, the repair results are evaluated and analyzed. The simulation results show that the algorithm can effectively overcome the shortcomings of blurred details and region extension in fixed dictionary restoration, and the restoration effect has been significantly improved. Compared with the results of several other classic algorithms, it shows the effectiveness of the algorithm in this paper. (shrink)
