Although the composition of the board of directors has important implications for different aspects of firm performance, prior studies tend to focus on financial performance. The effects of board composition on corporate social responsibility (CSR) performance remain an under-researched area, particularly in the period following the enactment of the Sarbanes-Oxley Act of 2002 (SOX). This article specifically examines two important aspects of board composition (i.e., the presence of outside directors and the presence of women directors) and their relationship with CSR (...) performance in the Post-SOX era. With data covering over 500 of the largest companies listed on the U.S. stock exchanges and spanning 64 different industries, we find empirical evidence showing that greater presence of outside and women directors is linked to better CSR performance within a firm’s industry. Treating CSR performance as the reflection of a firm’s moral legitimacy, our study suggests that deliberate structuring of corporate boards may be an effective approach to enhance a firm’s moral legitimacy.

Value co-creation goes through the stage of co-production, customer experience, service-dominant logic, and service ecosystem. The integration of science and technology has become a key factor to the process of VCC. The rise and application of artificial intelligence technology has added a new driving force to VCC and began to affect its original practical logic. Based on the consumer perspective, this study uses Q-methodology to measure consumer cognitive attitude toward the use of AI technology in VCC, aiming to explore the (...) key factors that affect VCC. The study found that content quality, information security, efficiency concern, and degree of manipulation have become the important concerns of consumers for VCC under AI integration. Moreover, their different statements have their specific focus and direction. The study demonstrates and analyzes the importance of the four factors and proposes the combination of human and non-human actors to shape the new model of VCC in the future, which is worth further deepening and exploring for academia and enterprises.

Multilevel item response theory models are used widely in educational and psychological research. This type of modeling has two or more levels, including an item response theory model as the measurement part and a linear-regression model as the structural part, the aim being to investigate the relation between explanatory variables and latent variables. However, the linear-regression structural model focuses on the relation between explanatory variables and latent variables, which is only from the perspective of the average tendency. When we need (...) to explore the relationship between variables at various locations along the response distribution, quantile regression is more appropriate. To this end, a quantile-regression-type structural model named as the quantile MLIRT model is introduced under the MLIRT framework. The parameters of the proposed model are estimated using the Gibbs sampling algorithm, and comparison with the original MLIRT model is conducted via a simulation study. The results show that the parameters of the Q-MLIRT model could be recovered well under different quantiles. Finally, a subset of data from PISA 2018 is analyzed to illustrate the application of the proposed model. (shrink)

We discuss the finite-to-one Rudin-Keisler ordering of ultrafilters on the natural numbers, which we baptize the Rudin-Blass ordering in honour of Professor Andreas Blass who worked extensively in the area. We develop and summarize many of its properties in relation to its bounding and dominating numbers, directedness, and provide applications to continuum theory. In particular, we prove in ZFC alone that there exists an ultrafilter with no Q-point below in the Rudin-Blass ordering.

We investigate whether female board representation and firms’ financial performance are related and whether the relationship differs for firms located in more prejudicial environments. As a proxy for prejudicial environment, we use two geographical indicators: whether a firm is headquartered in a conservative “red” state or in a liberal “blue” state and whether the firm is located in regions where residents possess more stereotypical attitudes about gender equality. We find that both financial performance and female board representation are lower for (...) firms headquartered in red states when compared to those in blue states, and we find similar results for firms located in regions where residents hold more gender-stereotypical views. However, financial performance improves when female directors are present regardless of the firm’s location. Evidence also shows that the incremental improvement in performance measured by Tobin’s q is greater in red-state than in blue-state companies and in regions where residents hold more gender-stereotypical views. The overall results imply that gender stereotyping holds back financial performance and that female directors help improve financial performance. (shrink)

Noise in behavior is often viewed as a nuisance: while the mind aims to take the best possible action, it is let down by unreliability in the sensory and response systems. How researchers study cognition reflects this viewpoint – averaging over trials and participants to discover the deterministic relationships between experimental manipulations and their behavioral consequences, with noise represented as additive, often Gaussian, and independent. Yet a careful look at behavioral noise reveals rich structure that defies easy explanation. First, both (...) perceptual and preferential judgments show that sensory and response noise may potentially only play minor roles, with most noise arising in the cognitive computations. Second, the functional form of the noise is both non-Gaussian and non-independent, with the distribution of noise being better characterized as heavy-tailed and as having substantial long-range autocorrelations. It is possible that this structure results from brains that are, for some reason, bedeviled by a fundamental design flaw, albeit one with intriguingly distinctive characteristics. Alternatively, noise might not be a bug but a feature: indeed, we suggest that noise is fundamental to how cognition works. Specifically, we propose that the brain approximates probabilistic inference with a local sampling algorithm, one that uses randomness to drive its exploration of alternative hypotheses. Reframing cognition in this way explains the rich structure of noise and leads to a surprising conclusion: that noise is not a symptom of cognitive malfunction but plays a central role in underpinning human intelligence.

In order to correct the deficiencies of intrusion detection technology, the entire computer and network security system are needed to be more perfect. This work proposes an improved k-means algorithm and an improved Apriori algorithm applied in data mining technology to detect network intrusion and security maintenance. The classical KDDCUP99 dataset has been utilized in this work for performing the experimentation with the improved algorithms. The algorithm’s detection rate and false alarm rate are compared with the experimental data before the (...) improvement. The outcomes of proposed algorithms are analyzed in terms of various simulation parameters like average time, false alarm rate, absolute error as well as accuracy value. The results show that the improved algorithm advances the detection efficiency and accuracy using the designed detection model. The improved and tested detection model is then applied to a new intrusion detection system. After intrusion detection experiments, the experimental results show that the proposed system improves detection accuracy and reduces the false alarm rate. A significant improvement of 90.57% can be seen in detecting new attack type intrusion detection using the proposed algorithm. (shrink)

Research in engineering ethics has assessed the ethical reasoning of students in mostly the US. However, it is not clear that ethical judgments are primarily the result of ethical reasoning, or that conclusions based on US samples would be true of global populations. China now graduates and employs more STEM (science technology engineering and mathematics) majors than any other country in the world, but the moral cognition and ethics education of Chinese engineers remains understudied. To address this gap, a study (...) was conducted examining the relations between ethical reasoning, moral intuitions, and ethics education among engineering students in China. Engineering students at a university in Shanghai, China completed measures of ethical reasoning and moral intuitions before and after a course on global engineering ethics. Among engineering students in China, (1) ethical reasoning is positively related to an emphasis on care and fairness and (2) global ethics education results in significantly higher levels of ethical reasoning, as well as a greater concern with fairness and loyalty. Whereas the relation between ethical reasoning and moral intuitions among engineering students in China is similar to that of students in the US, ethics education affects engineering students in China differently from their US counterparts.

The article argues that mainstream value-sensitive approaches to design have been based on narrow understandings of personhood and social dynamics, which are biased toward Western Educated Industrialized Rich and Democratic cultures and contradicted by empirical evidence. To respond to this weakness, the article suggests that design may benefit from focusing on user behaviours from the joint perspective of values and norms, especially across cultural contexts. As such, it proposes Norm Sensitive Design as a complement to value-sensitive approaches when designing and (...) implementing new technologies. Versus values, norms serve as more accurate predictors or descriptors of behaviours and can thus support value-sensitive approaches to realize the aspiration of informing user behaviour via design. The article makes two key contributions. On the theoretical side, it promotes the consideration of norms in design. On the practical side, it offers designers and instructors prompts for reflecting on design ethics from the perspective of norms. (shrink)

Since 2019, the COVID-19 pandemic, as a global public health emergency, has led to stringency measures of various degrees worldwide. As these measures such as social distancing measures and mandatory lockdown are intended to minimize social mobility, they have exerted remarkable impact on individuals’ mental health, particularly, adolescents and children. The mental health problems caused include fear, anxiety, sense of isolation and development of more maladaptive behaviors due to prolonged lockdown and restricted interpersonal contact. However, well adaption status and stable (...) interpersonal relationships play an important role in maintaining and promoting the mental health of adolescents and children. This study aims to gain a new sight of understanding of the mental health quality of Chinese adolescents during the COVID-19 Pandemic in terms of adaptation and interpersonal quality. The study is based on a survey on a total of 7,318 junior and senior high school students aged 12–18 years in various regions of China, and intended to examine the differences in adolescent mental health quality by sociodemographic variables such as gender, grade, urban and rural areas, only child, and parental education level. Our study finds that Chinese adolescents show an overall good adaptation and interpersonal quality during the lockdown. However there exists disparity across different categories in developmental patterns of adaptation and interpersonal quality. In addition, good family environment, moderate financial and emotional support, higher parental education level, etc. contribute to the cultivation and improvement of adolescents’ mental health quality. Finally, we suggest that the government and researchers should pay more attention to adolescents’ mental health issues in terms of adaption status and interpersonal relationships during the COVID-19 pandemic, especially for disadvantaged social groups such as girls, younger students, and low-income family students.

RésuméCet article se penche sur la réception des théories avicenniennes du mouvement au VIe/XIIe siècle. Avicenne a conçu des façons innovantes de comprendre le mouvement, répondant à la fois aux défis et conditions établis par la tradition philosophique antérieure et à ceux qui naissent de sa critique interne. Le mouvement est pour lui soit le mode d’être entre deux termes, soit le passage ou l'intervalle, le premier étant le type de mouvement extra-mentalement réel, tandis que le second est un produit (...) de l'imagination. Au VIe/XIIe siècle, la critique implicite conduite par certains savants prééminents aboutit, dans certains cercles, à l'adoption de la thèse selon laquelle le mouvement-passage est extra-mentalement réel. Cette position était jugée viable aussi bien par les tenants de l'atomisme que par ceux de la théorie de la continuité des corps. (shrink)

Law abidance is very important for effective leaders. Without law abidance, abuse of power and corruption would easily happen, which would eventually erode organizational health. To promote law abidance leadership in university students in Hong Kong, we developed a law abidance leadership program with 3 h of face-to-face lecture and 7 h of self-study of materials disturbed to students. To understand students’ perception of the 3-h lecture, we conducted a post-lecture evaluation study using a 26-item measure. Results showed that the (...) scale possessed good reliability and validity. Confirmatory factor analyses showed that the assessment tool has three internally consistent and factorial invariant dimensions: program attributes, appreciation of law abidance, and teacher attributes. Regarding students’ perception of the program, students were generally satisfied with the lecture attributes, including design, content, lecture atmosphere, teaching quality, and benefits to students. In particular, students agreed that the lecture helped them understand the importance and value of law abidance and national security; over 95% of the students indicated that they would try their best to serve as law-abiding citizens and socially responsible leaders. Multiple regression analyses showed that program attributes, appreciation of law abidance, and teacher attributes predicted overall satisfaction with the lecture. Qualitative comments of the student echoed the quantitative findings, with most of the comments being positive in nature. The present study replicated the findings reported previously. Local and international contextual factors relevant to the interpretations of the findings are highlighted. (shrink)

Psychological well-being indicates individuals’ positive psychological functioning and well-being. A growing body of literature, largely based on adults and old people, suggests that volunteering and charitable donations are related to individuals’ psychological well-being. As emerging adulthood is a vital time for lifespan development, the aim of this study is to examine the effects of volunteering and charitable donation on individuals’ psychological well-being on college students. Relying on theories of altruism and the warm-glow theory, this study estimates the relationships among hours (...) of volunteering, amount of charitable donations, and psychological well-being from 1,871 Chinese college students. The linear regression results indicate that students’ hours of volunteering and the amount of charitable donations in the past year were positively associated with their psychological well-being. Volunteering, compared to charitable donations, had a slightly stronger association with psychological well-being. This study provides a rationale for academic institutions to integrate social service activities into the curriculum as a potential tool to promote students’ psychological well-being. (shrink)
