This study investigates the impact of labor unionization on stock price crash risk. We find that labor unionization is negatively associated with stock price crash risk. Such negative relation is more pronounced when firms can intimate more credible evidence on unfavorable prospects and when firms face more powerful labor unions. Our findings are consistent with the notion that firms take strategic actions to reduce the bargaining advantages enjoyed by labor unions and that labor unions force firms to take less risky (...) investments and discontinue underperformed projects more timely, which leads to lower stock price crash risk.

Ming Hanedanlığı'nın sonlarında ve 17. yüzyılın ortalarındaki Qig Hanedanlığı'nın başlarında yaşamış olan Şeyh Wang Daiyu, Çinli Muhammed b. Abdullah b. Elias'tan sonra Çin'deki en meşhur Müslüman alimlerden biridir. Şeyh'in yaşadığı dönem, İslam'ın Çin'de yükselişe geçtiği bir döneme karşılık gelmektedir. Bu dönemde Şeyh Wang Daiyu; bilimsel makaleler ve kitaplar yazmaya başlamış, Kur'ân-ı Kerim ve Hz. Peygamber’in sünnetindeki İslami fikirleri açıklamak için bazı Konfüçyüsçü terimler almış ve Konfüçyüsçü fikirleri İslami fikirlerle uzlaştırmaya çalışmıştır. Aynı zamanda İslam'a davet, İslam kültürünü yayma ve (...) İslami yükseliş hakkında sistematik fikirler ortaya koyma vazifesini üstlenmiştir. Bu makale temel olarak Şeyh'in biyografisine, tarihsel arka planına ve Çin medeniyeti ile İslam medeniyetinin nasıl uzlaştırılacağına dair analitik bir araştırmaya odaklanmaktadır. Nitekim onun döneminde İslam büyük bir gelişme ve canlılık kazanmıştır. Buradan hareketle Şeyh Wang Daiyu'nun İslam kültürü ile Çin kültürünün etkileşimine büyük katkı sağladığını söyleyebiliriz. Bu makale, -dünyanın Çin’i (ve Çin’li Müslüman âlimleri) daha iyi tanıması maksadıyla- “Çin hikayelerini iyi anlatın” milli sloganını gerçekleştirmeyi amaçlamaktadır. Ayrıca araştırmacı, bin yılı aşkın bir süredir Çin'de İslam'a davet etmek ve İslam medeniyetini yaymak için koşturan, vatana ve millete büyük katkılar sunan Müslüman alimleri dünyaya tanıtmayı hedeflemektedir. Araştırmanın mümkün olduğunca eksiksiz olabilmesi için tarihsel ve analitik yöntem bir arada kullanılmıştır. Araştırmada; Şeyh Wang Daiyu’nun hayatı, eserleri, İslâm’ın onun dönemindeki özellikleri ve Şeyh’in, Çin medeniyeti ile İslam medeniyetini nasıl uzlaştırdığı gibi hususlar ele alınacaktır. (shrink)

Recent research in numerical cognition has begun to systematically detail the ability of humans and nonhuman animals to perceive the magnitudes of nonsymbolic ratios. These relationally defined analogs to rational numbers offer new potential insights into the nature of human numerical processing. However, research into their similarities with and connections to symbolic numbers remains in its infancy. The current research aims to further explore these similarities by investigating whether the magnitudes of nonsymbolic ratios are associated with space just as symbolic (...) numbers are. In two experiments, we found that responses were faster on the left for smaller nonsymbolic ratio magnitudes and faster on the right for larger nonsymbolic ratio magnitudes. These results further elucidate the nature of nonsymbolic ratio processing, extending the literature of spatial–numerical associations to nonsymbolic relative magnitudes. We discuss potential implications of these findings for theories of human magnitude processing in general and how this general processing relates to numerical processing. (shrink)

Objectives The objectives of the study are to understand the current practice of informed consent in medical research in public hospitals in Shanghai, and to share our views with other countries, especially developing countries. Methods In the study, 145 consent forms (CFs) of the selected research projects in eight public hospitals with ethics committees in Shanghai were audited, and the principle investigators (PIs) of these research projects and 40 student subjects who had participated in clinical drug tests were surveyed by (...) questionnaires. Results The CFs of medical researches in public hospitals with ethics committees in Shanghai were generally acceptable. However, there were some defects in the CFs. Although most of the surveyed PIs had correct recognition of informed consent, some processes of informed consent were not in accordance with generally accepted requirements. A large number of the PIs considered the greatest difficulty with informal consent was lack of correct recognition of subjects or legally authorised representatives on medical research. Discussion Informed consent in medical research should consider the research ethics, the background of potential subjects, the local resources and culture of medical research. In addition, special protection is needed for student subjects in informed consent as well as efforts for building and restoring the public's trust in biomedical research. Conclusion The informed consent in Shanghai's public hospitals with ethics committees was generally acceptable and the achievement of adequate informed consent is influenced by many factors.

Using the corpus of JSTOR articles, we investigate the role of gender in collaboration patterns across the scholarly landscape by analyzing gender-based homophily--the tendency for researchers to co-author with individuals of the same gender. For a nuanced analysis of gender homophily, we develop methodology necessitated by the fact that the data comprises heterogeneous sub-disciplines and that not all authorships are exchangeable. In particular, we distinguish three components of gender homophily in collaborations: a structural component that is due to demographics and (...) non-gendered authorship norms of a scholarly community, a compositional component which is driven by varying gender representation across sub-disciplines, and a behavioral component which we define as the remainder of observed homophily after its structural and compositional components have been taken into account. Using minimal modeling assumptions, we measure and test for behavioral homophily. We find that significant behavioral homophily can be detected across the JSTOR corpus and show that this finding is robust to missing gender indicators in our data. In a secondary analysis, we show that the proportion of female representation in a field is positively associated with significant behavioral homophily. (shrink)

In an era where decolonizing architectural pedagogy is imperative, cities stand as the forefront of radical thought, acting as crucibles for ideological, activist, and spatial dynamics. These urban landscapes are not just breeding grounds for new paradigms, but also reflect significant shifts in political and social frameworks. This study adopts the concept of the “radical city” as a prism to understand how local events echo global political and sociocultural disturbances. This research takes an innovative approach by integrating mixed-method pedagogies, student-driven (...) inquiries, and diverse case studies, spanning continents from Asia to Latin America, Europe to Africa, and the US to the UK. The aim is to explore the deep-rooted changes in these cities and to promote a decolonized approach to architectural education, moving beyond traditional, Eurocentric narratives. The backbone of this research is the course “Visualizing Radical Urbanism,” offered at the Huckabee College of Architecture, Texas Tech University, in Fall 2022 and Fall 2023. Through this course, students engage in a pedagogical journey involving exploration, research, analysis, and introspection on their selected radical city. Their diverse methodologies and expressive mediums converge in a comprehensive portfolio, showcasing their intellectual growth and culminating in a reflective essay on their urban subject. By focusing on educational research and time investment in this course, the study highlights the importance of sustained, critical engagement with urban environments. This approach not only enriches architectural education but also contributes to the broader discourse on urban activism and decolonization, reinforcing the need for diverse, inclusive, and globally aware architectural pedagogies.

Ethics is central to science and engineering. Young engineers need to be grounded in how corporate social responsibility principles can be applied to engineering organizations to better serve the broader community. This is crucial in times of climate change and ecological challenges where the vulnerable can be impacted by engineering activities. Taking a global perspective in ethics education will help ensure that scientists and engineers can make a more substantial contribution to development throughout the world. This paper presents the importance (...) of incorporating the global and cross culture components in the ethic education. The authors bring up a question to educators on ethics education in science and engineering in the globalized world, and its importance, necessity, and impendency. The paper presents several methods for discussion that can be used to identify the differences in ethics standards and practices in different countries; enhance the student’s knowledge of ethics in a global arena.

We extend research on the effects of local audit office characteristics on audit quality by investigating whether audit offices in highly religious U.S. Metropolitan Statistical Areas exhibit going concern decisions that reflect heightened professional skepticism relative to audit offices in less religious MSAs. Prior research links religiosity to risk aversion and ethical development and suggests audit practice offices in more religious MSAs are more likely to issue going concern opinions because they will assess the effects of mitigating factors in a (...) more skeptical manner. Our results indicate that audit practice offices located in highly religious MSAs are more likely to issue going concern audit opinions, consistent with a more skeptical assessment of mitigating factors. Additional tests provide direct evidence consistent with the argument that these audit offices are more risk averse in issuing going concern opinions. Our findings are relevant to auditors, audit clients, researchers, and regulators. (shrink)

While robots were traditionally built to achieve economic efficiency and financial profits, their roles are likely to change in the future with the aim to provide social support and companionship. In this research, we examined whether the robot’s proposed function (social vs. economic) impacts judgments of mind and moral treatment. Studies 1a and 1b demonstrated that robots with social function were perceived to possess greater ability for emotional experience, but not cognition, compared to those with economic function and whose function (...) was not mentioned explicitly. Study 2 replicated this finding and further showed that low economic value reduced ascriptions of cognitive capacity, whereas high social value resulted in increased emotion perception. In Study 3, robots with high social value were more likely to be afforded protection from harm, and such effect was related to levels of ascribed emotional experience. Together, the findings demonstrate a dissociation between function type (social vs. economic) and ascribed mind (emotion vs. cognition). In addition, the two types of functions exert asymmetric influences on the moral treatment of robots. Theoretical and practical implications for the field of social psychology and human-computer interaction are discussed. (shrink)

© Springer-Verlag Berlin Heidelberg 2015. When reasoning about knowledge of procedures under imperfect information, the explicit representation of epistemic possibilities blows up the S5like models of standard epistemic logic. To overcome this drawback, in this paper, we propose a new logical framework based on compact models without epistemic accessibility relations for reasoning about knowledge of procedures. Inspired by the 3-valued abstraction method in model checking, we introduce hyper models which encode the imperfect procedural information. We give a highly non-trivial 2-valued (...) semantics of epistemic dynamic logic on such models while validating all the usual S5 axioms. Our approach is suitable for applications where procedural information is ‘learned’ incrementally, as demonstrated by various examples. (shrink)

Our previous study has shown impaired blood oxygen level-dependent /functional magnetic resonance imaging activation of the visual attention network in strabismic amblyopia. However, there has been no comparison of resting state fMRI activation and functional connectivity in brain regions of interest along the visual attention network including visual cortex, intraparietal sulcus, and frontal eye fields during closed eye resting across the SA, or anisometropic amblyopes groups. Hence, we compared, gray matter volume, amplitude of low frequency fluctuations, regional homogeneity, and FC (...) in the left and right hemisphere ROIs of the visual attention network in SA, AA, and healthy controls. Correlation analyses of corrected visual acuity of amblyopic eye and MRI results were also performed and showed that the LogMAR cVA of the amblyopic eye positively correlated with right zALFF and zReHo FEF of SA and right IPS of AA only. GMV of both left and right hemisphere V1 areas was significantly greater but ALFF was significantly lower for SA compared to AA and HC groups. zALFF and zReHo analyses in the AA and SA groups indicated significantly higher activation than that in the HC group in the right FEF and IPS but lower than that in the HC group in the left FEF, and only the SA group showed lower activation in both V1 areas than the HC group. FC values of the right FEF–left V1, right FEF–right V1, and right FEF–right IPS pathways in the SA and AA groups were also significantly higher than those in the HC group whereas all other FC values were non-significant. Thus, this study indicates that even during resting-state the visual attention network function is impaired in SA and AA participants with only right hemisphere FEF showing significant activation in SA and IPS in AA suggesting that the slower saccade activation times characteristic of amblyopic eyes lead to the dominant eye controlling activation of the visual attention network.
