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)

Cyclin-dependent kinase 5 has been implicated in Alzheimer's disease pathogenesis. Here, we demonstrate that overexpression of p25, an activator of cdk5, led to increased levels of BACE1 mRNA and protein in vitro and in vivo. A p25/cdk5 responsive region containing multiple sites for signal transducer and activator of transcription was identified in the BACE1 promoter. STAT3 interacts with the BACE1 promoter, and p25-overexpressing mice had elevated levels of pSTAT3 and BACE1, whereas cdk5-deficient mice had reduced levels. Furthermore, mice with a (...) targeted mutation in the STAT3 cdk5 responsive site had lower levels of BACE1. Increased BACE levels in p25 overexpressing mice correlated with enhanced amyloidogenic processing that could be reversed by a cdk5 inhibitor. These data demonstrate a pathway by which p25/cdk5 increases the amyloidogenic processing of APP through STAT3-mediated transcriptional control of BACE1 that could have implications for AD pathogenesis.

Survival after solid-organ transplantation has improved significantly, and many contemporary transplant recipients are of childbearing potential. There are limited data to guide decision-making surrounding pregnancy after transplantation, variations in clinical practice, and significant knowledge gaps, all of which raise significant ethical issues. Post-transplant pregnancy is associated with an increased risk of maternal and fetal complications. Shared decision-making is a central aspect of patient counselling but is complicated by significant knowledge gaps. Stakeholder interests can be in conflict; exploring these tensions can (...) help patients to evaluate their options and inform their deliberations. We argue that uniform, evidence-based recommendations for pregnancy after solid organ transplantation are needed. Conducting research, including patient-engaged studies, in this area should be priority for the transplant community. (shrink)

Objective: The objectives of this study are to understand the current functions, structure and operation of hospital ethics committees (HECs) in Shanghai and to facilitate their improvement. Methods: (1) A questionnaire survey, (2) interviews with secretaries and (3) on-site document reviews of HECs in Shanghai were used in the study, which surveyed 33 hospitals. Results: In Shanghai, 57.56% of the surveyed hospitals established HECs from 1998 to 2005. Most HECs used bioethical review of research involving human subjects as well as (...) bioethical review or consultation regarding medical care services and administrative decision- making. Of the surveyed HECs, 14.3% did not provide any formal bioethical training to the HECs’ members and many HECs had no standard operating procedures. Some HECs had no clear definition of what was “conflict of interest” that should be considered by the HECs, while 44.4% of the HECs did not perform continuing review. Discussion: After the issues of related national regulations, more and more hospitals established HECs in Shanghai, but the functions of HECs need to be further developed and formal training on bioethics should be provided to HEC members. To assure the independence and good performance of HECs, the conflict of interest procedure, the standard operating procedures and bioethical review should be improved. Conclusion: HECs in Shanghai had developed in the preceding 10 years and they played great roles in protecting the rights and welfare of human subjects and patients; some areas need improvement.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Great Synthesis of Wang Yang Ming Neo-Confucianism in Korea: The Chonŏn (Testament) by Chŏng Chedu (Hagok) by Edward Y.J. ChungMaria Hasfeldt Long (bio)The Great Synthesis of Wang Yang Ming Neo-Confucianism in Korea: The Chonŏn (Testament) by Chŏng Chedu (Hagok). By Edward Y.J. Chung. Landham: Lexington Books, 2020. Pp. vii+ 351. Hardcover $137.00, isbn 978-1-7936-1469-8. The Korean Neo-Confucian tradition during the Chosŏn dynasty (1392–1910) was dominated (...) by the orthodox Sŏngnihak (School of Human Nature and Principle), which is also known as the Chŏngjuhak (Cheng–Zhu School). This school of Neo-Confucianism followed the doctrines and teachings of the Great Synthesizer Zhu Xi (1130–1200) to such a point that other Neo-Confucian schools were labeled as wrong and even persecuted until the late nineteenth century. One of these schools was Simhak (School of the Mind/Heart) established by the Chinese scholar Wang Yangming (1472–1529), which during the Ming dynasty (1382–1644) had grown to rival the Cheng–Zhu school. However, the academic-political power of the Cheng–Zhu school in Korea managed to suppress Yangming scholarship and maintain dominance throughout the dynasty. Despite that, a few scholars did take up the scholarship of Simhak in Korea, with the most influential being Chŏng Chedu, also known as Hagok (1649–1736) (p. 4). In his book, The Great Synthesis of Wang Yang Ming Neo-Confucianism in Korea: The Chonŏn (Testament) by Chŏng Chedu (Hagok), Edward Y.J. Chung presents not only an annotated translation of Hagok's main writings but also a look into intellectual scholarship that opposed the orthodoxy of the Cheng–Zhu school of Korea. This in-depth study and translation of Hagok into English was motivated by the lack of attention in Western scholarship on Korean Neo-Confucianism. It presents a study that goes beyond the three most famous scholars, Yi Hwang T'oegye (1501–1570), Yi I Yulgok (1536–1584), and Chŏng Yagyong Tasan (1762–1836), who founded the three mainstream schools of the Chosŏn dynasty. According to Chung, Hagok's writing not only represents important aspects of intellectual history but also serves as a fourth and lesser-known school of Korean Neo-Confucian thinking that should be placed on the same level as the other three. Unlike other Korean scholars who tried to take up the Yangming doctrine, Hagok did not care that the doctrine was prohibited. This set him apart from other scholars. Despite the Cheng–Zhu school being the "right learning," Hagok did not agree with the majority of it and based his theories on the Yangming doctrine. Although Hagok openly followed the Yangming doctrine, he did not do so blindly. [End Page 1] Hagok was aware that Yangming's theories had their flaws and he agreed with some theories of the Cheng–Zhu school (p. 7–8). This resulted in him trying to synthesize the two schools into one harmonious doctrine, which is why Chung believes Hagok to be important and has undertaken the task of bringing attention to this Korean scholar. Consisting of two distinct parts, Chung gives the reader a solid introduction to Hagok and his main theories via the selected translations from his most influential text, Chonŏn, which can be translated into "testament" or "living words." The first part of the book is divided into notes on the translation itself, such as transliteration, citation style, abbreviations, and, more importantly, how and why Chung selected the sections of the Chonŏn that have been translated. Through the selection, translation, annotation, and discussion of forty-one important essays from Chonŏn's three parts, Chung wishes to show the heart of Hagok's Neo-Confucian thought (p. x). The Chonŏn is not organized according to any thematic system and consists of different paragraphs, notes, and comments. Chung has, therefore, chosen which parts to translate in order to best portray Hagok's interpretation of the key concepts, the theories found in the Yangming Neo-Confucianism, and Hagok's criticism of Zhu Xi and T'oegye. All of this is properly introduced and explained in... (shrink)

Durante los días 16 al 23 de agosto se ha celebrado en la ciudad austriaca de Kirchberg am Wechsel un Congreso Internacional sobre Filosofía de la Matemática. La organización corría a cargo de la renovada Österreichische Ludwig Wittgenstein Geellschaft, que preside Rudolf Haller y cuenta con Jaakko Hintikka como principal scholar. El Congreso ha servido para reunir un buen número de especialistas en esta materia, entre los que figuran M. Dummett, H. Field, I. Grattan-Guinness, P. Maddy, Ch. Parsons, St. Shapiro (...) y H. Wang. Respecto del proyecto inicial sólo hubo una ausencia relevante: el profesor Crispin Wright, conocido especialmente en esta disciplina por su libro sobre la concepción fregeana del número como objeto y su estudio acerca del pensamiento wittgensteiniano sobre los fundamentos de la Matemática.

In his doctor's thesis [1], Henkin has shown that if a formal logic is consistent, and sufficiently complex, then it must admit a non-standard model. In particular, he showed that there must be a model in which that portion of the model which is supposed to represent the positive integers of the formal logic is not in fact isomorphic to the positive integers; indeed it is not even well ordered by what is supposed to be the relation of ≦.For the (...) purposes of the present paper, we do not need a precise definition of what is meant by a standard model of a formal logic. The non-standard models which we shall discuss will be flagrantly non-standard, as for instance a model of the sort whose existence is proved by Henkin. It will suffice if we and our readers are in agreement that a model of a formal logic is not a standard model if either: The relation in the model which represents the equality relation in the formal logic is not the equality relation for objects of the model. That portion of the model which is supposed to represent the positive integers of the formal logic is not well ordered by the relation ≦. That portion of the model which is supposed to represent the ordinal numbers of the formal logic is not well ordered by the relation ≦. (shrink)

The common liberal understanding of reproductive autonomy – characterized by free choice and a principle of non-interference – serves as a useful way to analyse the normative appeal of having certain choices open to people in the reproductive realm, especially for issues like abortion rights. However, this liberal reading of reproductive autonomy only offers us a limited ethical understanding of what is at stake in many kinds of reproductive choices, particularly when it comes to different uses of reproductive technologies and (...) third-party reproduction. This is because the liberal framework does not fully capture who benefits from which reproductive options, the extent of the risks and harms involved in various reproductive interventions, and the reasons for why people are driven to make certain reproductive choices.

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.

Abortion is the deliberate termination of a pregnancy. In current practice, this involves the death of the foetus. Consequently, the debate on whether those experiencing an unwanted pregnancy have the right to abortion is usually dichotomized as a matter of pro-choice versus pro-life. Pro-choice advocates maintain that abortion is acceptable under various circumstances. The idea that we ought to respect pregnant people’s rights to choose what to do with their bodies – respect for bodily autonomy – is cited as a (...) major reason for granting them abortion rights. Pro-life advocates, on the other hand, claim that abortion is not acceptable under most circumstances. They argue, typically, that the foetus has a right to life. Recent events, such as Poland’s High Court decision in October 2020 to ban most abortions, and the huge protests and outcries this generated around the world, indicate that the abortion debate is far from resolved.

We present the logic K/2 which is a logic with classical implication and only the left part of classical negation.We show that it is possible to define a classical negation into K/2 and that the classical proposition logic K can be translated into this apparently weaker logic.We use concepts from model-theory in order to characterized rigorously this translation and to understand this paradox. Finally we point out that K/2 appears, following Haack's distinction, both as a deviation and an extension of (...) K. (shrink)

Literature on testimonial injustice and ways that perpetrators might combat it have flourished since Miranda Fricker’s ground-breaking work on testimonial injustice. Less attention has been given, however, to the role of bystanders. In this paper, I examine the accountability that bystanders may have for their omissions to redress testimonial injustice. I argue that bystander accountability applies in cases where it is opportune for bystanders to intervene, and if they are also sufficiently equipped and able to redress the testimonial injustice. Moreover, (...) I recommend that we move beyond virtue responsibilism for ameliorative thinking about testimonial injustice. (shrink)
