Background: Physical exercises can affect executive function both acutely and chronically, with different mechanisms for each moment. Currently, only a few reviews have elaborated on the premise that different types of exercises have different mechanisms for improving executive function. Therefore, the primary purpose of our systematic review was to analyze the effects of acute and chronic exercises on executive function in children and adolescents.Objective: We identified acute and chronic exercise studies and randomized controlled trials of executive function in children and (...) adolescents that reported overall effect, heterogeneity, and publication bias of acute and chronic exercises on executive function.Methods: We searched for RCTs of exercise interventions in children and adolescents from databases including PubMed, Web of Science, Scopus, The Cochrane Library, CNKI, and Wanfang, from January 1 2009 to December 31 2019. We performed methodological quality evaluations on the included literature using the Physiotherapy Evidence Database Scale and graded evidence with a meta-analysis using Stata 12.0 software.Results: In total, 36 RCTs were included ; the overall results of the meta-analysis indicated that acute exercises significantly improved working memory = −0.72; 95% confidence interval −0.89 to −0.56; p < 0.001), inhibitory control, and cognitive flexibility, whereas chronic exercises significantly improved working memory, inhibitory control, and cognitive flexibility.Conclusion: Acute and chronic exercises can effectively improve the executive function of children and adolescents. The effects on inhibitory control and cognitive flexibility are considered as small effect sizes, while the effects on working memory are considered as moderate effect size. Limited by the quantity and quality of the included studies, the above conclusions need to be verified with more high-quality studies. (shrink)

Considering that motor and cognitive processes are intertwined and inhibit or help each other throughout life and that primary school age is one of the most critical stages of children's cognitive and motor development, this study aimed to investigate the relationship between executive functions and gross motor skills in Chinese children aged 9–10 years, as well as gender differences. The flanker task, the 1-back task, the more-odd shifting task, and the test of gross motor coordination were used to collect data (...) on executive functions and gross motor coordination. The results were as follows. First, there was a weak association between gross motor coordination and the inhibition reaction time in the congruent test and the reaction time of working memory, but no association was found between gross motor coordination and cognitive flexibility. Second, a weak-to-moderate correlation was presented between the move sideways test and the inhibition reaction time in the congruent test and the reaction time in the refreshing test of the working memory. Finally, gender influenced on the relationship between gross motor coordination and the reaction time of both inhibition and working memory. To conclude, our results suggest that children with better motor coordination skills require less reaction time, especially girls, and this association was more substantial than in boys. The finding supports the current assertion that there are commonalities between gross motor coordination and cognitive control by showing the relationship between gross motor coordination and complex cognitive processes in preadolescent children.

The stock market is a chaotic, complex, and dynamic financial market. The prediction of future stock prices is a concern and controversial research issue for researchers. More and more analysis and prediction methods are proposed by researchers. We proposed a hybrid method for the prediction of future stock prices using LSTM and ensemble EMD in this paper. We use comprehensive EMD to decompose the complex original stock price time series into several subsequences which are smoother, more regular and stable than (...) the original time series. Then, we use the LSTM method to train and predict each subsequence. Finally, we obtained the prediction values of the original stock price time series by fused the prediction values of several subsequences. In the experiment, we selected five data to fully test the performance of the method. The comparison results with the other four prediction methods show that the predicted values show higher accuracy. The hybrid prediction method we proposed is effective and accurate in future stock price prediction. Hence, the hybrid prediction method has practical application and reference value. (shrink)

The field of eSports is undergoing a process of developing and evolving with irresistible forces. The process witnesses the ever-refreshing and hybrid meanings and definitions of Sports and eSports in the digital era of technology empowerment and advancing artificial intelligence. This paper calls us to re-construct the meanings and sporting values of eSports, re-evaluate the eSports landscape, going beyond the debate ‘Are eSports Sports?’ and move to re-examine the contextual nature and values of Sports and eSports, as well as their (...) interweaving relationships in contemporary society. It is of significance to explore the way in which the intelligent embodiment of eSports and the virtualisation of traditional sports integrate with each other, offering the potential for fitness and physical exercises and practices in real and virtual spaces. Meanwhile, crucial digital ethics issues are emerging in the field of eSports, potentially challenging and alerting the eSports industry to take timely measurements to maintain the Sport’s integrity.

This paper provides a systematic and critical review of the existing literature on the phenomenon of ‘commercial contract cheating’ (CCC). Unlike some existing systematic reviews _generally_ on CCC, this paper focuses on the potential causes and suggested preventative measures specifically, intending to develop effective interventions on the basis of empirical insights. We reviewed primary studies with empirical data and systematic reviews focusing on higher education published between 2012 and 2020. A logic model is developed to graphically indicate the complex and (...) dynamic interplay between a variety of factors identified. Our inquiry reveals a highly specified, uncoordinated and fragmented research landscape that urgently needs integrated, holistic and critical reflection. It shows that the current research is still far from establishing causal relationships as the scholarship opts to reveal an abundance of contextual factors identified only, without probing the relational dynamics or striving for causality. A range of broad and tentative recommendations are proposed on that basis but are barely empirically examined. We also attend to lack of conceptual clarity and work towards a more inclusive and future-proof definition of CCC beyond assignment-based conceptualisation. It is argued that CCC should never be reduced to plagiarism (a natural inclination inspired by the plagiarism research tradition) nor neutralised as a legitimate business (a potential risk revealed mostly by the supply side research). As an interdisciplinary field, CCC should move beyond student perceptions of education cheating and affordability, while including more inquiries into the exploitative, predatory nature of the industry.

This paper aims at analyzing the distinctive features of the western and Chinese philosophies, which underlie the western and Chinese cultures. Westerners focus on the form, and they are deeply influenced by geometry and materialized philosophies. Meanwhile, Chinese people focus on connotation, and they are greatly influenced by the yin-and-yang principle.

In this article, we examine the empirical association between firm value and CSR engagement for firms in sinful industries, such as tobacco, gambling, and alcohol, as well as industries involved with emerging environmental, social, or ethical issues, i.e., weapon, oil, cement, and biotech. We develop and test three hypotheses, the window-dressing hypothesis, the value-enhancement hypothesis, and the value-irrelevance hypothesis. Using an extesive US sample from 1995 to 2009, we find that CSR engagement of firms in controversial industries positively affects firm (...) value after controlling for various firm characteristics. To address the potential endogeneity problem, we further estimate a system of equations and change regression and continue to find a positive relation between CSR engagement and firm value. Our findings support the value-enhancement hypothesis and are consistent with the premise that the top management of US firms in controversial industries, in general, considers social responsibility important even though their products are harmful to human being, society, or environment.

Seminal work by Knobe, Prasada, and Newman (2013) distinguished a set of concepts, which they named “dual‐character concepts.” Unlike traditional concepts, they require two distinct criteria for determining category membership. For example, the prototypical dual‐character concept “artist” has both a concrete dimension of artistic skills, and an abstract dimension of aesthetic sensibility and values. Therefore, someone can be a good artist on the concrete dimension but not truly an artist on the abstract dimension. Does this analysis capture people's understanding of (...) cornerstone social categories, such as gender, around which society and everyday life have traditionally been organized? Gender, too, may be conceived as having not only a concrete dimension but also a distinct dimension of abstract norms and values. As with dual‐character concepts, violations of abstract norms and values may result in someone being judged as not truly a man/woman. Here, we provide the first empirical assessment of applying the dual‐character framework to people's conception of gender. We found that, on some measures that primarily relied on metalinguistic cues, gender concepts did indeed resemble dual‐character concepts. However, on other measures that depicted transgressions of traditional gender norms, neither “man” nor “woman” appeared dual‐character‐like, in that participants did not disqualify people from being truly a man or truly a woman. In a series of follow‐up studies, we examined whether moral norms have come to replace gender role norms for the abstract dimension. Implications for the evolution of concepts and categories are explored. (shrink)

In this study, we examine the relation between corporate environmental responsibility and risk in U.S. public firms. We develop and test the risk-reduction, resource-constraint, and cross-industry variation hypotheses. Using an extensive U.S. sample during the 1991–2012 period, we find that for U.S. industries as a whole, CER engagement inversely affects firm risk after controlling for various firm characteristics. The result remains robust when we use firm fixed effect or an alternative measure of CER using principal component analysis or downside risk (...) measures. To address the concern of endogeneity bias, we use a system equations approach and dynamic system generalized methods of moment regressions, and continue to find that environmentally responsible firms experience lower risk. These findings support the risk-reduction hypothesis, but not the resource-constraint hypothesis, along with the notion that the top management in U.S. firms is generally risk averse and that their CER engagement facilitates their risk management efforts. Our cross-industry analysis further reveals that the inverse CER-risk association mainly comes from the manufacturing sector, whereas in the service sector, CER tends to increase firm risk. (shrink)

BackgroundAging and type 2 diabetes mellitus are important risk factors for the development of cognitive deterioration and dementia. The objective of this research was to investigate the effects of an exercise intervention on cognitive function in older T2DM patients.MethodsEight literature databases were searched from inception to 20 January 2022. The researchers examined randomized controlled trials that evaluated the impact of exercise on the cognitive performance of older T2DM patients. The Cochrane risk-of-bias tool for RCTs was used to assess each study. (...) The quality of evidence was assessed using the GRADE approach. The mini-mental state examination, Modified MMSE, and Montreal cognitive assessment were used to evaluate the cognitive outcomes. We performed a subgroup analysis with stratification according to exercise intervention modality, duration, and cognitive impairment.ResultsFive trials were eligible, with a total of 738 T2DM patients. The combined findings revealed that exercise improved global cognitive function significantly. In the studies that were included, no relevant adverse events were reported.ConclusionExercise is beneficial in improving global cognitive function in older adults with T2DM. Studies with bigger sample sizes and higher quality are additionally expected to draw more definite conclusions.Systematic Review Registration[https://www.crd.york.ac.uk/PROSPERO/#recordDetails], identifier [CRD42022296049].

This paper uses an innovative way to screen stocks and analyzes the relationship between corporate environmental responsibility and long-run stock returns. By our definition, an environmentally responsible (green) company gives no environmental concern and shows environmental strength(s). Using 20 years’ data of 1992–2011, we find evidence that environmentally responsible company outperforms, in the 4th to 7th year after the screening year. An equal-weighted environmentally responsible portfolio earned an annual four-factor alpha of 4.06 % in the 4th year, 3.00 % above (...) industry benchmarks, and 3.87 % above characteristic benchmarks. The results are robust to alternative portfolio weighting methodologies, controlling for firm characteristics, and the removal of outliers. Testing using industry-adjusted Tobin’s Q, we find consistent evidence that environmental strength creates firm value. We argue that environmental responsibility is an intangible asset, likely to be undervalued by the market, especially in the long horizon, thereby causing environmentally responsible companies to exhibit long-horizon excess returns.

This study aims to identify the influence of knowledge management practices on the entrepreneurial and organizational performance with the mediating effect of dynamic capabilities and moderating role of opportunity recognition. Data were gathered from 486 entrepreneurs and applied a structural equation model to test the hypotheses. We found that knowledge management practices have a positive and significant influence on dynamic capabilities, as well as have a significant impact on entrepreneurial and organizational performance. Moreover, results indicated that dynamic capabilities partially mediate (...) in the relationship between knowledge management practices on entrepreneurial and organizational performance. Furthermore, the relationship between knowledge management practices with entrepreneurial and organizational performance strengthening by opportunity recognition. Further, implications and limitations were discussed in the paper. (shrink)

The article explores a gradual refinement of the notion of reflection in Husserlian phenomenology. In his early period, Husserl takes phenomenological reflection to attain adequate evidence, since its object is self-given in an absolute and complete manner. However, this conception of reflection does not remain unchanged. Husserl later realizes that immanent perception or phenomenological reflection also involves a certain horizonality and naivety that has to do with its temporal nature and must be queried in a further critical, apodictic reflection. Focusing (...) more on the notion of apodicticity than adequacy, Husserl subsequently ascribes a new methodological role to reflection: instead of a mere epistemic warrant that guarantees for us the ultimate truth of our experiential life once and for all, phenomenological reflection ensures the strictness of phenomenology insofar as it entails an ethical-existential dimension as the norm of a life-form where the subject pursues full self-understanding and self-justification.

Reproductive diseases are a long‐standing problem and have become more common in the world. Currently, 15% of the world's population suffers from infertility, and half of them are women. Maturation of oocytes, successful fertilization, and high‐quality embryos are prerequisites for pregnancy. With the development of assisted reproductive technology and advanced genetic assays, we have found that infertility in many young female patients is caused by mutations in various developmental regulators. These pathogenic factors may result in impediment of oocyte maturation, failure (...) of fertilization or early embryonic development arrest. In this review, we categorize these clinically‐identified, mutated genetic factors by their molecular characteristics: nuclear factors (PALT2, TRIP13, WEE2, TBPL2, REC114, MEI1 and CDC20), cytoplasmic factors (TLE6, PADI6, NLRP2/5, FBXO43, MOS and BTG4), a factor unique to primates (TUBB8), cell membrane factor (PANX1), and zona pellucida factors (ZP1‐3). We compared discrepancies observed in phenotypes between human and mouse models to provide clues for clinical diagnosis and treatment of related reproductive diseases. (shrink)

The human conceptual system comprises simulated information of sensorimotor experience and linguistic distributional information of how words are used in language. Moreover, the linguistic shortcut hypothesis predicts that people will use computationally cheaper linguistic distributional information where it is sufficient to inform a task response. In a pre‐registered category production study, we asked participants to verbally name members of concrete and abstract categories and tested whether performance could be predicted by a novel measure of sensorimotor similarity (based on an 11‐dimensional (...) representation of sensorimotor strength) and linguistic proximity (based on word co‐occurrence derived from a large corpus). As predicted, both measures predicted the order and frequency of category production but, critically, linguistic proximity had an effect above and beyond sensorimotor similarity. A follow‐up study using typicality ratings as an additional predictor found that typicality was often the strongest predictor of category production variables, but it did not subsume sensorimotor and linguistic effects. Finally, we created a novel, fully grounded computational model of conceptual activation during category production, which best approximated typical human performance when conceptual activation was allowed to spread indirectly between concepts, and when candidate category members came from both sensorimotor and linguistic distributional representations. Critically, model performance was indistinguishable from typical human performance. Results support the linguistic shortcut hypothesis in semantic processing and provide strong evidence that both linguistic and grounded representations are inherent to the functioning of the conceptual system.

In Spain, the introduction of the new Diploma in Nursing in 1977 saw the role of nurses shifting from that of medical assistants with technical skills to being independent members of the healthcare team with specific responsibility for providing professional nursing care. Here, we analyse the evolution of the nursing profession in Spain following the transfer of nurse education to universities, doing so through interviews with the first generation of academic tutors. This was a qualitative study using the method of (...) analytic induction and based on the principles of grounded theory. Participants were selected by means of theoretical sampling and then underwent in‐depth interviews. Steps were taken to ensure the credibility, transferability, dependability and confirmability of data. The main conclusion of the analysis is that there is a gap between a theoretical framework borrowed from the Anglo‐American context and a nursing practice that, in Spain, has traditionally prioritised the application of technical procedures, a role akin to that of a medical assistant. It is argued that a key factor underlying the way in which nursing in Spain has evolved in recent decades is the lack of conceptual clarity regarding what the role of the professional nurse might actually entail in practice.

Interpersonal Needs Questionnaire is a self-report measure of perceived burdensomeness and thwarted belongingness with five versions in recent studies. There are five versions of INQ. But results from studies using different versions are quite different. Current suicide behavior among teenagers has attracted much attention. But which version is more suitable for teenage samples is still uncertain. It is important to compare the potential differences in different versions of INQ to identify the most psychometrically available version to predict teenagers' acquired capability (...) for suicide and provide them with timely help to reduce teenagers' suicide rates. This study compared the construct validity, internal consistency, validity, and average test information of each version in the sample of teenagers. Results showed the 10-item version provided the most average test information in both thwarted belongingness subscale and perceived burdensomeness subscale, and the INQ-10 is more suitable for teenage samples.

Recently, decomposition-based multiobjective evolutionary algorithms have good performances in the field of multiobjective optimization problems and have been paid attention by many scholars. Generally, a MOP is decomposed into a number of subproblems through a set of weight vectors with good uniformly and aggregate functions. The main role of weight vectors is to ensure the diversity and convergence of obtained solutions. However, these algorithms with uniformity of weight vectors cannot obtain a set of solutions with good diversity on some MOPs (...) with complex Pareto optimal fronts. To deal with this problem, an improved decomposition-based multiobjective evolutionary algorithm with adaptive weight adjustment is proposed. Firstly, a new method based on uniform design and crowding distance is used to generate a set of weight vectors with good uniformly. Secondly, according to the distances of obtained nondominated solutions, an adaptive weight vector adjustment strategy is proposed to redistribute the weight vectors of subobjective spaces. Thirdly, a selection strategy is used to help each subobjective space to obtain a nondominated solution. Comparing with six efficient state-of-the-art algorithms, for example, NSGAII, MOEA/D, MOEA/D-AWA, EMOSA, RVEA, and KnEA on some benchmark functions, the proposed algorithm is able to find a set of solutions with better diversity and convergence.
