Much of the mathematics with which Felix Klein and Sophus Lie are now associated (Klein’s Erlangen Program and Lie’s theory of transformation groups) is rooted in ideas they developed in their early work: the consideration of geometric objects or properties preserved by systems of transformations. As early as 1870, Lie studied particular examples of what he later called contact transformations, which preserve tangency and which came to play a crucial role in his systematic study of transformation groups and differential equations. (...) This note examines Klein’s efforts in the 1870s to interpret contact transformations in terms of connexes and traces that interpretation (which included a false assumption) over the decades that follow. The analysis passes from Klein’s letters to Lie through Lindemann’s edition of Clebsch’s lectures on geometry in 1876, Lie’s criticism of it in his treatise on transformation groups in 1893, and the careful development of that interpretation by Dohmen, a student of Engel, in his 1905 dissertation. The now-obscure notion of connexes and its relation to Lie’s line elements and surface elements are discussed here in some detail. (shrink)

RÉSUMÉDans ses écrits de Jena, Fichte tente de résoudre l’apparent conflit entre la nécessité de faire reposer la philosophie sur des principes scientifiques et celle de respecter sa nature de vocation autonome. Ce faisant, il a prétendu accomplir d’autres tâches, sur les plans métaphilosophique, pédagogique et polémique : justifier les questions qui l’occupaient, communiquer sa pensée correctement et répondre aux incompréhensions de ses adversaires. Cet article montre qu’à travers ces considérations, Fichte s’essaie aussi au problème plus vaste qui consiste à (...) préciser la relation entre la «lettre» de la philosophie comme doctrine et son «esprit» intersubjectif.

In lieu of an abstract, here is a brief excerpt of the content:230 Feminist Studies 47, no. 1. © 2021 by Feminist Studies, Inc. Nneka D. Dennie The State and Future of Black Women’s Studies: The Black Women’s Studies Association and the National Women’s Studies Association in Conversation On February 25, 2021, the Black Women’s Studies Association (BWSA) and National Women’s Studies Association (NWSA) partnered for one of NWSA’s Kitchen Table Talks—a new initiative spearheaded by NWSA President Kaye Wise Whitehead (...) to foster dialogue between NWSA and other organizations. The event, titled “Space Making: State/Future of Black Women’s Studies,” featured three panelists and was moderated by Whitehead. The featured speakers were Stephanie Andrea Allen (BWSA conference chair), Jacinta R. Saffold (BWSA co-founder and treasurer), and Erica L. Williams (member of the NWSA Governing Council). Allen is a Black lesbian writer and publisher whose scholarship examines how lesbian literature and film responds to and resists the heteropatriarchal systems that invisibilize Black lesbians; she is a postdoctoral fellow and visiting assistant professor of gender studies at Indiana University. Saffold is an assistant professor of English at the University of New Orleans who researches twentieth- and twenty-first-century African American literature, hip hop studies, and digital humanities. Williams is an associate professor of anthropology at Spelman College, whose work has examined sex tourism and Black feminist activism in Brazil. Together, Whitehead, Allen, Saffold, and Williams explored their hopes for Black Women’s Studies and illuminated the challenges and joys of advancing the field. News and Views 231 The collaboration between BWSA and NWSA is a testament to how far Black Women’s Studies has come over the past fifty years and a promise of where it may continue to go in the future. NWSA was founded in 1977 and has since served as a hub for researchers, educators, and practitioners who interrogate questions of women and gender in their work. For decades, NWSA has been central to the nationwide US institutionalization of women’s, gender, and sexuality studies. By contrast, BWSA is a young organization that is continuing to grow. In 2018, Saffold and I co-founded BWSA in order to provide a community for scholars working in the field of Black Women’s Studies. BWSA is the only professional association specifically designed to bring scholars from a variety of disciplines into conversation about research that centers Black women. We launched BWSA with the goal of ensuring that future generations of scholars can readily access networks and mentorship from researchers who encounter a common question: when your work is simultaneously “too Black” and “too woman” for your field, department, or institution, what do you do? Drawing inspiration from well-established organizations in which we frequently participated, such as NWSA, the Association for the Study of African American Life and History (ASALH), the Association of Black Women Historians (ABWH), and the African American Intellectual History Society (AAIHS), Saffold and I sought to build a space that cultivated a Black feminist ethic of care for both the research and the researchers. In that spirit, BWSA provides resources to help scholars do their best work, including a mentorship program, a virtual writing community, a calls-for-papers list for publications, and article as well as graduate student paper prizes. It was an honor to join an organization as trusted and respected as NWSA for a dialogue about our shared visions for Black Women’s Studies. Three key themes emerged from the panelists’ conversation with each other. They repeatedly returned to the importance of making financial commitments to Black Women’s Studies, creating conditions to support Black women’s intellectual labor, and practicing self-care. Speakers explored the interplay between the responsibilities that institutions, communities, and individuals have to Black Women’s Studies and Black feminist scholars. They observed that in order for departments and universities to foster interdisciplinary work on Black women, they need to move beyond paying lip service to the idea that diversity, equity, and inclusion matter; there needs to be permanent funding for work on race, 232 News and Views gender, class, and sexuality. Panelists also emphasized that Black women being in community with each other and supporting one another have always been central to... (shrink)

Scepticism about ought simpliciter is the view that there is no such thing as what one ought simpliciter to do. Instead, practical deliberation is governed by a plurality of normative standpoints, each authoritative from their own perspective but none authoritative simpliciter. This paper aims to resist such scepticism. After setting out the challenge in general terms, I argue that scepticism can be resisted by rejecting a key assumption in the sceptic’s argument. This is the assumption that standpoint-relative ought judgments bring (...) with them a commitment to act in accordance with those judgments. Instead, I propose an alternative account of our normative concepts according to which only ought simpliciter judgments commit one to acting in accordance with those judgments. In addition to answering the sceptical challenge, the proposal offers an independently motivated account of what makes a concept normatively authoritative. (shrink)

This paper examines the general prospects for conceptual role expressivism, expressivist theories that embrace conceptual role semantics. It has two main aims. The first aim is to provide a general characterisation of the view. The second aim is to raise a challenge for the general view. The challenge is to explain why normative concepts are not a species of defective concepts, where defective concepts are those that cannot meaningfully embed and participate in genuine inference. After rejecting existing attempts to answer (...) the challenge, I propose an alternative solution. However, the solution leaves conceptual role expressivism a far less distinctive and interesting position than its proponents claim. I conclude that we should be sceptical about how much expressivists gain by appealing to conceptual role semantics. (shrink)

Beylikler devri Türk-İslam ciltleri hem tezyînatları hem de üzerlerindeki dini içerikli ibareler, dua ve mücellid mühürleri vasıtasıyla cilt sanatı araştırmacılarının yayınlarına konu olmuştur. Ancak ciltlerdeki dua ifadelerini müstakil olarak konu edinen yayın sayısı oldukça azdır. Türk-İslam ciltlerinin gerek kapak yüzeyinde gerekse kapak içlerinde dua içerikli ibarelere rastlamak mümkündür. Makalenin konusu, Beylikler devrinde üretilen Türk-İslam ciltlerinin deri kaplı kapak içlerinde yer alan el-İzzü’d-Dâim ve’l-İkbâl (العزّ الدّائم والإقبال) yazısı, bu yazının yer aldığı desen kompozisyonu ve yazının analizidir. Makaledeki amaç, şimdiye kadar cilt (...) literatüründe müstakil olarak ele alınmamış el-İzzü’d-Dâim ve’l-İkbâl yazılı cilt kapak içi tezyînatı hakkında tespit edilebilen örneklerin detaylı desen ve yazı analizleriyle bilimsel birikim oluşturabilmek ve aynı ya da benzer ibarenin yer aldığı diğer İslam sanat eserlerini tespit ederek bu dua ibaresinin ciltlerdeki kullanım amacını ve kullanıldığı dönemleri belirlemeye çalışmaktır. Cilt sanatı literatürü ve yazma eser kütüphanelerinde yaptığımız araştırmalar neticesinde, Beylikler dönemine ait ciltlerin altı tanesinin kapak içinde el-İzzü’d-Dâim ve’l-İkbâl ibaresi tespit edilmiştir. Bu tespitlerin sayısı, yapılacak yeni araştırmalarla artabilecektir. Tespit edilen yazma eserler; Amasya YEK: 217, İnebey YEK Hüseyin Çelebi: 481 ve Ulu Cami: 318, Kastamonu YEK: 2856 ve 3435 ve Süleymaniye YEK Fatih: 5004’tür. Ciltlerin kapak, sertâb ve mikleb yüzeylerindeki tezyînatları, Beylikler dönemi cilt sanatı üslûbunu yansıtan süslemelerdir. Ciltlerin teknik ve tezyînatları, -mevcut olanların- istinsâh kayıtları incelendiğinde üç örneğin (Amasya YEK: 217, Kastamonu YEK: 2856 ve 3435) 14. yüzyıl tarihli olduğu ya da tarihlendirildiği, üç örneğin (İnebey YEK Hüseyin Çelebi: 481 ve Ulu Cami: 318, Süleymaniye YEK Fatih: 5004) ise 15. yüzyıl tarihli olduğu ya da tarihlendirildiği görülmektedir. Ciltlerin kapak içi deseni, bitkisel ve rûmî motiflerle bezeli tam zemin geometrik bir tasarıma sahiptir. Geometrik desenin içerisindeki altıgen paftalarda el-İzzü’d-Dâim ve’l-İkbâl (العزّ الدّائم والإقبال) yazısı yer almaktadır. İbarenin, cilt kapak içlerine tek satırda (İnebey YEK Ulu Cami: 318, Kastamonu YEK: 3435) ve çift satırda -½ oranında ters simetrik- (Amasya YEK: 217, İnebey YEK Hüseyin Çelebi: 481, Kastamonu YEK: 2856, Süleymaniye YEK Fatih: 5004) olmak üzere iki türde yazıldığı tespit edilmiştir. Her iki tasarımda da sülüs yazı çeşidi tercih edilmiştir. İnebey YEK Hüseyin Çelebi: 481 envanter numaralı 15. yüzyıla ait cildin kapak içinde ise diğer örneklerden farklı olarak yazı paftalarının bazılarında mücellit kitabesi bulunmaktadır. Kitabede, “Amel-i Mücellid Haydar b. Turbegî” yazılıdır. Kapak içi tezyînatının aynı olması nedeniyle, Kastamonu YEK: 2856 ve Süleymaniye YEK Fatih: 5004 envanter numaralı ciltlerin de Haydar b. Turbegî adlı mücellidin eseri olma ihtimali vardır. Ciltlerin kapak içlerinin tümü, çeşitli tonlarda kahverengi sahtiyanla kaplıdır. Derilerin gözenek türü bunu ispat eder niteliktedir. Süsleme tekniği, tüm kapak içlerinde soğuk baskı tekniğidir. Bu teknik adını, uygulanması esnasında altının kullanılmamasından almaktadır. Soğuk baskı tekniğinde, desenin deriye genellikle sıcak pres uygulaması yapılarak aktarıldığı bilinmektedir. Uygulamada yüzeyinde motif veya desenin yer aldığı kalıp, çivi ve diğer ciltçilik aletleri kullanılmaktadır. Çalışma kapsamındaki ciltlerde kapak içi deseninin kalıpla uygulandığı, deri üzerindeki desenin kesintili çizgilerden anlaşılmaktadır. Kapak içi tezyînâtını oluşturan desenin simetrik bir parçası, kalıba işlenmiş ve kalıp deri üzerine simetrik bir şekilde, boşluk bırakılmadan basılmıştır. Yapılan incelemelerden anlaşıldığı kadarıyla kalıbın basıldığı deri, kapak içine yapıştırıldıktan sonra kapak kenarlarından cilt ebadına uygun şekilde kesilmiş olmalıdır. Kalıbın bazı örneklerde hatalı basıldığı da görülmektedir. Bu da desenin devamlılığını kısmen bozmuştur. Soğuk baskı tekniğinde, desenin deriye genellikle sıcak pres uygulaması yapılarak aktarıldığı bilinmektedir. Desenin deri renginden daha açık olması, uygulamanın ısıyla yapılmış olduğunu doğrulamaktadır. Ciltlerin kapak yüzeylerinin kullanıma bağlı olarak yıprandığı ve bu nedenle desenlerin deforme olduğu tespit edilmiştir. Ancak kapak içleri böyle bir yıpranmaya maruz kalmadıkları için korunarak günümüze ulaşmıştır. el-İzzü’d-Dâim ve’l-İkbâl (العزّ الدّائم والإقبال) ibaresi Arapça bir terkip olup “sonsuz güç ve yüksek mevki” anlamına gelmektedir. Terkip; güç, kudret ve ihtişam anlamına gelen العزّ ve ferah, parlak ve yüksek mevki anlamındaki الإقبال kelimelerinden oluşmaktadır. İbare dua, temenni vb. maksatlarla kullanılmış olmalıdır. Çalışma kapsamındaki ciltler ve diğer İslam sanatı örneklerinden anlaşıldığı kadarıyla İslam sanat eserleri üzerinde el-İzzü’d-Dâim ve’l-İkbâl ibaresine 12. yüzyıldan 15. yüzyıla kadar geniş bir dönemde yer verilmiştir.

This paper examines the integration and unification of the philosophy and psychology of well-being. For the most part, these disciplines investigate well-being without reference to each other. In recent years, however, with the maturing of each discipline, there have been a growing number of calls to integrate the two. While such calls are welcome, what it means to integrate well-being philosophy and psychology can vary greatly depending on one’s theoretical and practical ends. The aim of this paper is to provide (...) a novel conceptual framework for thinking about integrating well-being philosophy and psychology that systematically categorizes different kinds of integration projects. We divide existing attempts in the literature into three broad categories according to the perspective from which the integration takes place: (1) top-down meta-theoretical unification; (2) psychological integration within philosophy; and (3) philosophical integration within psychology. These categories are then broken down into various further subcategories. Our aim in providing this framework is both to facilitate the assessment and comparison of existing integration attempts and to provide a roadmap for future integration attempts. For each category, we discuss one or two representative examples of the approaches. By doing so, we hope to generate interest in the wide variety of existing integration projects, as well as to generate discussion concerning the benefits and pitfalls of different approaches.

It has become increasingly difficult for individuals to exercise meaningful control over the personal data they disclose to companies or to understand and track the ways in which that data is exchanged and used. These developments have led to an emerging consensus that existing privacy and data protection laws offer individuals insufficient protections against harms stemming from current data practices. However, an effective and ethically justified way forward remains elusive. To inform policy in this area, we propose the Ethical Data (...) Practices framework. The framework outlines six principles relevant to the collection and use of personal data—minimizing harm, fairly distributing benefits and burdens, respecting autonomy, transparency, accountability, and inclusion—and translates these principles into action-guiding practical imperatives for companies that process personal data. In addition to informing policy, the practical imperatives can be voluntarily adopted by companies to promote ethical data practices. (shrink)

The coronavirus disease-2019 (COVID-19) has caused shortages of life-sustaining medical resources, and future waves of the virus may cause further scarcity. The Yale New Haven Health System developed a triage protocol to allocate scarce medical resources during the COVID-19 pandemic, with the primary goal of saving the most lives possible, and a secondary goal of making triage assessments and decisions consistent, transparent, and fair. We outline the process of developing the protocol, summarize the protocol, and discuss the major ethical challenges (...) encountered, along with our answers to the challenges. These challenges include (1) the role of age and chronic comorbidities; (2) evaluating children and pregnant patients; (3) racial, ethnic, and socioeconomic disparities in health; (4) prioritization of healthcare workers; and (5) balancing clinical judgment versus protocolized assessments.We conclude with a review of the limitations of our protocol and the lessons learned. We hope that a robust public discussion of such protocols and the ethical challenges they raise will result in the fairest possible processes, less need for triage, and more lives saved during future waves of the pandemic and similar public health emergencies.

A general equation is derived describing the concentration of all possible complexes of a central molecule with a set of ligands bound to the central molecule. This deduction allows the reaction rate constants for the binding of a given molecule to the central molecule to depend on the species of molecules already bound and the location of the molecules already bound. The model thus allows for structural alteration of the central molecule by binding. Functions describing the concentration dependence of any (...) effect whatever depending on the distribution of complexes are deduced. Possible applications and methods of application are indicated.II est dérivé une équation qui décrit la concentration des toutes les complexes d'une molécule centrale avec une collection de ligands connectés à la molécule centrale.

As innovations in the field of vascular composite allotransplantation (VCA) progress, whole-eye transplantation (WET) is poised to transition from non-human mammalian models to living human recipients. Present treatment options for vision loss are generally considered suboptimal, and attendant concerns ranging from aesthetics and prosthesis maintenance to social stigma may be mitigated by WET. Potential benefits to WET recipients may also include partial vision restoration, psychosocial benefits related to identity and social integration, improvements in physical comfort and function, and reduced surgical (...) risk associated with a biologic eye compared to a prosthesis. Perioperative and postoperative risks of WET are expected to be comparable to those of facial transplantation (FT), and may be similarly mitigated by immunosuppressive protocols, adequate psychosocial support, and a thorough selection process for both the recipient and donor. To minimize the risks associated with immunosuppressive medications, the first attempts in human recipients will likely be performed in conjunction with a FT. If first-in-human attempts at combined FT-WET prove successful and the biologic eye survives, this opens the door for further advancement in the field of vision restoration by means of a viable surgical option. This analysis integrates recent innovations in WET research with the existing discourse on the ethics of surgical innovation and offers preliminary guidance to VCA programs considering undertaking WET in human recipients.

The manuscript tradition of Seneca'sDialoguesconsists of one eleventhcentury manuscript, Ambrosianus C 90 inf., which is the main source for the text, and a ruck of later manuscripts of lesser and disputed worth. There are over a hundred of these, far more than has been supposed.

Upshot: Conversational conferences are difficult to design in a way that avoids the consequences that arise when participants are not experienced with or fully value the conversational mode of interaction. So, the designers of such conferences must experiment with ways to build a culture, use a structure, and facilitate participation that might mitigate some of these consequences. The potential of the experimental conference designed in the light of second-order cybernetics lies, in part, in the prospect of identifying and acquiring the (...) conversational abilities and appreciations necessary to support a participative-dialogic society.

Open peer commentary on the article “The Banathy Conversation Methodology” by Gordon Dyer, Jed Jones, Gordon Rowland & Silvia Zweifel. Upshot: The Banathy Conversation Methodology offers an approach to organizing and facilitating conversation groups among individuals self-identified as interested in a particular topic. As someone who would like to see more conversation integrated into academic conferences, I propose two extensions of BCM for consideration by the authors: one is an extension to the theoretical underpinnings, namely the conversation theory of Gordon (...) Pask, and the other is an extension to the tools and techniques, namely the group syntegration process developed by Stafford Beer. If the authors do not like the direction these extensions might take BCM, I would be interested in their assessment of the circumstances under which alternative approaches to conversation groups might be more or less useful.

Context: A tension exists between the needs and desires of the institutions providing the funding for academics to attend conferences and the potential for transforming the knowledge and understanding of conference participants - than in advancing their own careers and celebrity. Approaches to the problem can recognize the importance of funding and career-building in the current society, while still experimenting in ways that could generate new ideas. Method: Ideas from second-order cybernetics are used to derive design principles that might alleviate (...) the tension and encourage deep conversations, idea generation and experimentation. The author draws on experiences with designing, organizing and participating in cybernetics conferences over a period of 34 years. Results: An academic conference designed to a set of broad, second-order cybernetic principles, where participants are informed of the design intent before they decide to attend, can open an opportunity for learning, understanding and the creation of new ideas in ways that would not otherwise be available. Although there are no guarantees, such designs can attenuate the tension, often experienced at traditionally designed conferences, between advancing individual careers/celebrity and building new knowledge together. Implications: The design principles derived, already exhibited in some conferences, could be useful to organizers wishing to foster incompatible and opposing ideas and facilitate dialogue among conference participants. These same principles have implications for the design of other social systems and point to the possibility of a new and more humane society. Constructivist content: A feature of second-order cybernetics is that knowledge is continually changing as our desires change, and we must take responsibility for the consequences of the ideas we construct and use to satisfy our desires. Key Words: Design by constraint, dynamics of interaction, asynchronicity, tyranny of the clock, times of truth, moments of art. (shrink)

Open peer commentary on the article “A Cybernetic Approach to Contextual Teaching and Learning” by Philip Baron. Upshot: The idea of personal, customized education has been around for a while, and few disagree that it would be superior to what we have now in most public education systems worldwide. So, the questions are: Why has it not been more broadly implemented? And what would it take to make it the dominant approach to education?

Open peer commentary on the article ““Black Box” Theatre: Second-Order Cybernetics and Naturalism in Rehearsal and Performance” by Tom Scholte. Upshot: Scholte proposes using the theatre as a laboratory for experimenting with ideas in second-order cybernetics, adding to the repertoire of approaches for advancing this way of thinking. Second-order cybernetics, as art, science and craft, raises questions about the forms of experimentation most useful in such a laboratory. Theatre provides an opportunity to “play” with the dynamics of human interactions and (...) relations and possibly demonstrate value in second-order cybernetic thinking. (shrink)

Research in face recognition has tended to focus on discriminating between individuals, or “telling people apart.” It has recently become clear that it is also necessary to understand how images of the same person can vary, or “telling people together.” Learning a new face, and tracking its representation as it changes from unfamiliar to familiar, involves an abstraction of the variability in different images of that person's face. Here, we present an application of principal components analysis computed across different photos (...) of the same person. We demonstrate that people vary in systematic ways, and that this variability is idiosyncratic—the dimensions of variability in one face do not generalize well to another. Learning a new face therefore entails learning how that face varies. We present evidence for this proposal and suggest that it provides an explanation for various effects in face recognition. We conclude by making a number of testable predictions derived from this framework. (shrink)

This work examines the claim to scienific status made by supporters and practitioners of neoclassical economics. The approach taken is that of the history and philosophy of science. Analysis points to the conclusion that theories of economic choice are necessarily normative, essentially because of the nature of human behavior.

The COVID-19 pandemic laid bare systemic inequities shaped by social determinants of health (SDoH). Public health agencies, legislators, health systems, and community organizations took notice, and there is currently unprecedented interest in identifying and implementing programs to address SDoH. This special issue focuses on the role of medical-legal partnerships (MLPs) in addressing SDoH and racial and social inequities, as well as the need to support these efforts with evidence-based research, data, and meaningful partnerships and funding.
