It is fairly usual to argue or to assume that there is a single pattern of proper scientific endeavor for the behavioral sciences. This is based, one is inclined to say, on the superb model afforded by the natural science successes of the past few hundred years and on the common method which underlies and determines that model. Consequently, a protagonist can argue that within his own science, all opposed modes of thinking are archaic, peripheral, or unscientific, while his own (...) at least prefigures fulfillment of true science. And it may even be claimed that other behavioral fields are special offshoots, subordinate provinces, or particularizations which are reducible to his favored scheme of analysis. Such diversity and disagreement as there is, it can be said, stems from either of two causes. The first is the stubbornness of men, whereby they refuse to face the facts, to employ reasoning processes properly, or to foresake sinister interests. The other is the relative immaturity of behavioral science, an immaturity which will be eliminated by patient progress. (shrink)

Reflecting current debates on ‘organizational virtues’ as going beyond the capitalocentrist bias of contemporary economies and to see diversity as ‘ethical responsibility,’ this article explores ‘ethical organizing’ at the intersection of alternative organizations and diversity. Our interest in a diversity-oriented analysis of alternative organizations stems from the assumption that those which question taken-for-granted notions of existing economies and follow alternative values of autonomy, solidarity, and responsibility might also be likely to challenge existing diversity relations and, thus, (...) potentially open up new avenues for ethical organizing. Discussing our findings in terms of Lewis and Simpson’s (in)visibility vortex, our study shows that even though organizations position themselves discursively as ‘alternative,’ this positioning is not related to diversity issues. We conclude that a shift is needed to fully constitute ethical organizing, namely the establishment of a strong connection between alternative organizations’ virtues with, e.g., the feminist, anti-racist, queer, and disability rights movements.

Omnipresent calls for more women in university administration assume these women will prioritize using resources and power to increase female representation, especially in STEM fields where women are most underrepresented. However, empirical evidence is lacking for systematic differences in female versus male administrators’ attitudes. Do female administrators agree on which strategies are best, and do men see things differently? To answer this question, we explored United States college and university administrators’ opinions regarding policies, strategies, and structural changes in their (...) organizations designed to increase women professors’ representation and retention in STEM fields. A comprehensive review of past research yielded a database of potentially-effective, recommended policies (e.g., increasing emphasis on teaching, service, and administration during promotion reviews; stopping the tenure clock for childbearing; providing on-campus childcare; couples-hiring; sharing tenure lines; having more women chair search committees; setting gender quotas for promotion). A survey based on these recommended policies was sent to provosts, deans, associate deans, and department chairs of STEM fields at 96 public and private research universities (formerly called R1s) across the U.S. These administrators were asked to rate the quality and feasibility of each recommended policy; 474 provided data, of which 334 contained complete numerical data used in the analyses, so our results are based on a large, geographically diverse group of administrators at research universities. Our data revealed that female administrators perceived the 44 strategies to be higher in quality overall than did male administrators--but not higher in feasibility--with 9 policies perceived differently when rated by women versus men administrators, after imposing conservative statistical controls. There was broad general agreement on the relative rankings of the 44 policies in terms of their perceived quality. Overall, our national survey of U.S. administrators supported the assertion that placing women in administrative roles creates greater emphasis on the importance of enacting policies to attract and retain women in STEM. Topics of disagreement between women and men regarding strategy quality are important focuses of future policy and planning, because female administrators may have insights into how to retain women professors that male administrators do not share.

I investigate the reciprocal relationship between social accounts of knowledge production and efforts to increase the representation of women and some minorities in the academy. In particular, I consider the extent to which feminist social epistemologies such as Helen Longino’s critical contextual empiricism can be employed to argue that it is in researchers’ epistemic interests to take active steps to increase gender diversity. As it stands, critical contextual empiricism does not provide enough resources to succeed at this task. However, (...) considering this view through an employment equity lens highlights areas where such theories need to be further developed. I argue that views such as Longino’s ought to attend to nuances of community structure and cultural features that inhibit critical social interactions, if we are to maximize the epistemic as well as the ethical improvements associated with a social approach to knowing. These developments advance these epistemic theories for their own sake. They also help develop these theories into a tool that can be used by those calling for increased diversity in the academy.

Since its inception in the Middle Ages, the university classroom can be characterized by students gathered around a sage who imparts his or her knowledge. However, the effective classroom of today looks vastly different: First-year engineering students not only learn basic engineering principles, but are also guided to consider their own inner values and motivations as they design and build adaptive devices for people with disabilities; students in a large chemistry lecture work animatedly together in small groups on inquiry-based activities (...) while an instructor and teaching assistants circulate and guide their learning; students learning differential equations practice explicit metacognitive skills while problem-solving in class. Even though educational research, especially research that is targeted at STEM disciplines, demonstrates what most effectively engages students and supports their learning, many of today's classrooms look much like they did a century ago, with a professor delivering a primarily one-way lecture and students passively sitting in seats bolted to the floor. At this juncture in history, colleges and universities face a public call to engage a more diverse representation of students in effective learning, persistence, and degree attainment, and to do so economically and efficiently. It is essential that institutions draw upon methods demonstrated to effectively increase student learning and success. Educational researchers have thoroughly explored the "basic" science in this area, and a body of literature documents effective evidence-based instructional practices, hereafter referred to as EBIPs.

A large body of scientific careers literature explores the experiences of underrepresented minorities in STEM fields and why they exit the academic pipeline at various stages. These studies commonly address how to improve racial diversity in science but provide little discussion of why that diversity is important for science research. Feminist science studies scholars, on the other hand, have theorized about the importance of diversity in knowledge production for decades but provide little empirical work on how (...) to address current disparities. My research bridges these literatures by examining how diversity programs in the sciences justify their continued funding, and how these justifications map onto contemporary theories of knowledge production. Do diversity program directors seek to increase diversity in science because of political motives, like equality and justice for racial minorities, or because they believe that racially diverse workforces will produce better science? Based on interviews with federally-funded diversity program directors at universities and archival data from these programs, I find that program directors’ responses can be classified into three categories: diversity is important politically, diversity is important pragmatically, and diversity is important epistemically. About half of the respondents found diversity to be important for the content of scientific knowledge. I argue that studying diversity in scientific knowledge production is different than studying the impacts of diversity in other fields due to current conceptions of scientific objectivity. Scholarship on scientific knowledge production can help diversity program directors and science careers scholars better articulate the need for diversity programming in STEM fields. (shrink)

In recent years and months, human stem cell research has dominated many scientists' interests, the media, public debate, and social policy. This paper aims to consider, first, the major scientific data on stem cell research that are available. Second, I reflect on them by examining how they shaped policies in Europe and the United States. I also point to current changes in policy-making concerning the creation of ad hoc committees to address this novel issue and how, in a (...) few instances, different ethical positions are part of the documents produced. In other words, diverse approaches are not solved but kept in tension. Finally, I suggest that the current state of research on human stem cell will benefit from an ethics of risk. (shrink)

The COVID-19 outbreak spurred unplanned closures and transitions to online classes. Physical environments that once fostered social interaction and community were rendered inactive. We conducted interviews and administered surveys to examine undergraduate STEM students’ feelings of belonging and engagement while in physical isolation, and identified online teaching modes associated with these feelings. Surveys from a racially diverse group of 43 undergraduate students at a Hispanic Serving Institution (HSI) revealed that interactive synchronous instruction was positively associated with feelings of interest (...) and belonging, particularly for students of color, while noninteractive instruction reduced social belonging, but was related to more cognitive engagement. Small group and one-on-one interviews with 23 of these students suggest that students derived feelings of connectedness from their instructors, peers, and prior experiences and relied on their sense of competency to motivate themselves in the course and feel a sense of belonging. Two embedded cases of students in physics classrooms are compared to highlight the range of student feelings of connectedness and competency during the lockdown. Findings reaffirm that social interaction tends to support belonging and engagement, particularly for under-represented (Black or African American and Hispanic) racial groups in STEM. STEM instructors who aim to support feelings of belonging and engagement in virtual learning environments should consider increasing opportunities for student–student and student–teacher interactions, as well as taking a flexible approach that validates and integrates student voice into instruction. Future research is needed to further explore the themes of relatedness and competency that emerged as aspects of course belonging. (shrink)

The sources of embryos for Embryonic Stem Cell Research include surplus embryos from infertility treatments, and research embryos which are created solely for an ESCR purpose. The latter raises more ethical concerns. In a multi-religious country like Malaysia, ethical discussions on the permissibility of ESCR with regard to the use surplus and research embryos are diversified. Malaysia has formulated guidelines influenced by the national fatwa ruling which allows the use of surplus embryos in ESCR. Input from other main religions (...) is yet to be documented. In light of this, this study addresses the ethical viewpoints of Buddhist, Hindu and Catholic leaders on the permissibility of using surplus and research embryos; and the moral standpoints of religious leaders towards attaining a consensus on the practice of ESCR in Malaysia. Responses from the religious leaders were obtained via semi-structured, face-to-face interviews. The findings show that generally the Buddhist and Hindu leaders approve the use of surplus embryos. Their responses on the creation of research embryos for ESCR are varied. Meanwhile, the Catholic leaders distinctively objected to ESCR regardless of the embryo sources, referring to it as the destruction of life. Taking into account the diverse views, this study explores the response of the religious leaders for a general consensus wherever possible. The ethical discourse surrounding ESCR in a multi-religious setting offers new perspective, which needs to be explored in a broader global community. (shrink)

Acetylation of histones is an essential element regulating chromatin structure and transcription. MYST (Moz, Ybf2/Sas3, Sas2, Tip60) proteins form the largest family of histone acetyltransferases and are present in all eukaryotes. Surprisingly, until recently this protein family was poorly studied. However, in the last few years there has been a substantial increase in interest in the MYST proteins and a number of key studies have shown that these chromatin modifiers are required for a diverse range of cellular processes, both in (...) health and disease. Translocations affecting MYST histone acetyltransferases can lead to leukemia and solid tumors. Some members of the MYST family are required for the development and self‐renewal of stem cell populations; other members are essential for the prevention of inappropriate heterochromatin spreading and for the maintenance of adequate levels of gene expression. In this review we discuss the function of MYST proteins in vivo. (shrink)

This article centres on two distinct but intersecting questions: does it matter if we cannot definitively answer the question ‘what is philosophy?’ and do philosophers exhibit bias? The article will answer ‘yes’ to both questions for the following reasons. First because the uncertainty has allowed some answers to dominate. Second, because the answers necessarily demonstrate biases, and these have led to a lack of diversity in the discipline. Following this, the article will consider why philosophers have been slow or (...) reluctant to accept that bias plays a role in what we do. This lack of recognition has, I suggest, limited opportunity for diverse approaches, methods, and standpoints to flourish. The discipline has suffered as a result, and so too have diverse philosophers. Many fields in science, technology, engineering and mathematics meanwhile have sought to tackle the lack of diversity head on, and philosophers would do well to heed their examples. (shrink)

Despite the National Science Foundation's recent clarification of the Broader Impacts Criterion used in grant evaluation, it is not clear that this criterion is being understood or applied consistently by grant writers or reviewers. In particular, there is still confusion about how to interpret the requirement for broadening the participation of under-represented groups in science and scepticism about the value of doing so. Much of this stems from uncertainty about why the participation of under-represented groups is desirable or beneficial in (...) the first place. This paper distinguishes three different rationales for the importance of diversity in science and draws out the implications for the kind of diversity that is desirable, as well as how the diversity requirement of the Broader Impacts Criterion should be applied and weighed against other criteria in reviewing particular grants. I argue that there are epistemic, as well as social, benefits to diversity that can help promote scientific progress. (shrink)

In recent years, live imaging has been adopted to study stem cells in their native environment at cellular resolution. In the skeletal muscle field, this has led to visualising the initial events of muscle repair in mouse, and the entire regenerative response in zebrafish. Here, we review recent discoveries in this field obtained from live imaging studies. Tracking of tissue resident stem cells, the satellite cells, following injury has captured the morphogenetic dynamics of stem/progenitor cells as they (...) facilitate repair. Asymmetric satellite cell division generated a clonogenic progenitor pool, providing in vivo validation for this mechanism. Furthermore, there is an emerging role of stem/progenitor cell guidance at the injury site by cellular protrusions. This review concludes that live imaging is a critical tool for discovering the distinct processes that occur during regeneration, emphasising the importance of imaging in diverse animal models to capture the entire scope of stem cell functions.

In this paper we set out to explore the enactments of risk by clinicians involved in the development of stem cell therapy for liver disease. In the process, we contribute to a performative re-thinking of how ‘risk’ can be analytically treated in relation to health. The bulk of the paper, drawing on interview data, is concerned with how clinicians’ accounts about the risks entailed in their research-oriented work performatively ‘make’ clinicians themselves, but also various other ‘constituencies’ – notably, publics (...) and regulatory actors, and also such diverse ‘entities’ as scientific rigour and ethics. We trace the ways in which they enact the complexities of taking risks in the context of public demands, regulatory constraints, and resource limitation and explore how clinicians tend to represent themselves as caught between the ‘rock of courage’ and the ‘hard place of caution’.

Ethics is a philosophical branch of inquiry that reasons between what is right and wrong. The moral philosophy of Socrates, Aristotle, and Plato from ancient Greek became the basis of most of the western ethics. These days, ethics can be divided based on its inquiries for example, normative, descriptive, metaethics, and applied ethics or based on its theories like utilitarianism, emotivism, and universal ethics. In context with applied ethics that examines issues involving emerging technologies, this study will look into the (...) ethics of Malaysian stem cell technology based on written literature. It was mainly to identify Malaysian literature on stem cell ethics through conventional search since the mainstream international database indicated an obvious shortage. The critical review of this literature will facilitate in the understanding of unique position of Malaysia towards stem cell and its ethics in reference to the limited number. Despite the limitation, this can be a preliminary study urging for more inquiries and exploration to fulfil the multiple perspectives in ethics such as the diversity of Malaysian ethics, the impact of ethics in stem cell regulation in Malaysia, and if western contemporary ethics influences Malaysian ethics particularly involving stem cell technology.

Gaining ethical clearance to conduct a study is an important aspect of all research involving humans but can be time-consuming and daunting for novice researchers. This article stems from a larger ethnographic study that examined research capacity building in Irish nursing and midwifery. Data were collected over a 28-month time frame from a purposive sample of 16 nurse or midwife research fellows who were funded to undertake full-time PhDs. Gaining ethical clearance for their studies was reported as an early ‘rite (...) of passage’ in the category of ‘labouring the doctorate’. This article penetrates the complexities in Irish clinical research ethics by describing the practices these nurse and midwife researchers encountered and the experiences they had. The key issue of representation that occurred in the context of ‘medicalized’ research ethics is further explored including its meaning for nursing or midwifery research. (shrink)

Recent studies of prostate cancer and other tumor types have revealed significant support, as well as unexpected complexities, for the application of concepts from normal stem cell biology to cancer. In particular, the cell of origin and cancer stem cell models have been proposed to explain the heterogeneity of tumors during the initiation, propagation, and evolution of cancer. Thus, a basis of intertumor heterogeneity has emerged from studies investigating whether stem cells and/or non‐stem cells can serve (...) as cells of origin for cancer and give rise to tumor subtypes that vary in disease outcome. Furthermore, analyses of putative cancer stem cells have revealed the genetically diverse nature of cancers and expanded our understanding of intratumor heterogeneity and clonal evolution. Overall, the principles that have emerged from these stem cell studies highlight the challenges to be surmounted to develop effective treatment strategies for cancer. (shrink)

This critical examination of STEM discourses highlights the imperative to think about educational reforms within the diverse cultural contexts of ongoing environmental and technologically driven changes. Chet Bowers illuminates how the dominant myths of Western science promote false promises of what science can achieve. Examples demonstrate how the various science disciplines and their shared ideology largely fail to address the ways metaphorically layered language influences taken-for-granted patterns of thinking and the role this plays in colonizing other cultures, thus maintaining (...) the myth that scientific inquiry is objective and free of cultural influences. Guidelines and questions are included to engage STEM students in becoming explicitly aware of these issues and the challenges they pose. (shrink)

In recent years an uneasy peace has descended in U.S. academe between those who feel research universities have done too little to advance the representation of minority groups and women and those who feel that the administrative policies developed to improve representation can and sometimes do come into conflict with core intellectual commitments of universities.

The paper draws on the theory of strategic action fields to illuminate the structure and dynamics of the conflict and suggests modifications to the theory that would improve its explanatory power for this case.

Stem cell tourism is a small but growing part of the thriving global medical tourism marketplace. Much stem cell research remains at the experimental stage, with clinical trials still uncommon. However, there are over 700 clinics estimated to be operating in mostly developing countries – from Costa Rica and Argentina to China, India and Russia – that have lured many patients, mostly from industrialized countries, driven by desperation and hope, which in turn continue to fuel the growth of (...) such tourism.While much research has focused on such dimensions as the promotions that allow such businesses to make their services known, media coverage, some patient research, and regulatory conditions for developing country clinics, little attention has been paid to the non-affected members of the general population, the future potential users of such services. This empirical study based on five focus group discussions with a diverse group of healthy adults in a Canadian city, explored participant views of patients who use stem cell tourism services, the likelihood they would avail themselves of such services if they were to suffer similar illnesses, and the conditions under which they might do so, and the impact that admonitions and advice from international expert bodies might have on their decisions. Our findings suggest that these healthy adults are sympathetic to the drivers of hope and desperation, and, despite cautions about research limitations, may seek such treatments themselves under similar conditions. These findings are discussed in the context of the policy and ethical issues raised by this form of medical tourism. (shrink)

Recent developments in 3D cultures exploiting the self‐organization ability of pluripotent stem cells have enabled the generation of powerful in vitro systems termed brain organoids. These 3D tissues recapitulate many aspects of human brain development and disorders occurring in vivo. When combined with improved differentiation methods, these in vitro systems allow the generation of more complex “assembloids,” which are able to reveal cell diversities, microcircuits, and cell–cell interactions within their 3D organization. Here, the ways in which human brain organoids (...) have contributed to demystifying the complexities of brain development and modeling of developmental disorders is reviewed and discussed. Furthermore, challenging questions that are yet to be addressed by emerging brain organoid research are discussed. (shrink)

Understanding aging and how it affects an organism's lifespan is a fundamental problem in biology. A hallmark of aging is stem cell senescence, the decline of functionality, and number of somatic stem cells, resulting in an impaired regenerative capacity and reduced tissue function. In addition, aging is characterized by profound remodeling of the immune system and a quantitative decline of adequate immune responses, a phenomenon referred to as immune‐senescence. Yet, what is causing stem cell and immune‐senescence? This (...) review discusses experimental studies of potentially immortal Hydra which have made contributions to answering this question. Hydra transcription factor FoxO has been shown to modulate both stem cell proliferation and innate immunity, lending strong support to a role of FoxO as critical rate‐of‐aging regulator from Hydra to human. Constructing a model of how FoxO responds to diverse environmental factors provides a framework for how stem cell factors might contribute to aging. (shrink)

This article asserts that European and North American feminisms are colonial discursive elaborations that defined what it was to be a woman and a feminist. The categories of gender and patriarchy established both what the subordination of women was as well as the possibilities for their emancipation. They're colonial discourses in the sense that they have construed women of the third world, or of the global South, as “other.” The specific case examined in this article questions the Euro-US-centric feminist construction (...) of women and Afro-descendant feminists. In resignifying the categories of analysis proposed by feminism, such as gender and patriarchy, Afro-descendant feminists assert themselves as diverse Black women who build proposals subverting the social order that oppresses them, without needing to resort to feminism's central categories. Women belonging to ethnic communities elaborate a new type of feminism constructed in relation to the community's collective actions in vindicating their rights. Finally, Black or Afro-Colombian women, based on the legacy of their maroon or runaway slave ancestors, construct feminism otherwise, challenging universalist claims by Eurocentric and Andean-centric feminism, transforming and enriching it.

Epistemology of science is currently polarized. Descriptive accounts of the social aspects of science coexist uneasily with normative accounts of scientific knowledge. This tension leads students of science to privilege one of these important aspects over the other. I use an episode of recent immunology research to develop an integrative account of scientific inquiry that resolves the tension between sociality and epistemic success. The search for the hematopoietic stem cell by members of Irving Weissman’s laboratory at Stanford University Medical (...) Center exhibits both the goal-oriented character of contemporary immunology and the importance of social interactions in successful achievement of those goals. This episode includes three kinds of epistemic success: characterization of HSC, formation of new interdisciplinary interfaces, and reconciliation of apparently incompatible models. All three depend on coordinating the work of diverse participants via social interactions. Together, they reveal the crucial role of social interactions within and between research groups in producing epistemic success. These features of the search for the HSC generalize to immunology as a whole, and plausibly to other disciplines. This account thus resolves the polarizing tension in epistemology of science, and complements individualistic accounts of scientific knowledge and rationality. (shrink)

Introduction. The Chinese language, unlike Russian, has several terms, denoting different statuses of Chinese migrants, but there is no term such as “diaspora”. These features are interpreted by the authors along the lines of social ontology as independent sociological concepts, constructing particular migrant groups. The article’s oobjective is to show their internal coherence and correlation with the notion of “diaspora” as well as to outline the difficulties and problems occurring as the result of the interaction between researchers dealing with the (...) topic. The relevance of the study stems from the fact that researchers have paid little attention to differences in national academic discourses that are meanwhile very important because intercultural differences can only be negotiated if there is an understanding of what they are. With regard to diaspora discussions, this understanding has yet to be developed. The article shows that in diaspora studies there is a language barrier, which at the moment is currently an impassable obstacle for authors who write about the diaspora in different languages.Methodology and sources. To work on the article, the authors used a discursive analysis of academic texts on Chinese migration and Chinese migrants, as well as dictionaries and official documents such as the Large Chinese-Russian Dictionary, the Tsihai Dictionary (辞海 ci hai – Sea of words), the Large Russian Encyclopedia, State Council resolutions, and Chinese legislation.Results and discussion. The treatment of 10 terms replacing the notion of “diaspora” in Chinese language is disclosed. The authors describe characteristic features of each group. It is illustrated that there is a linguistic asymmetry, as a result of which the European notion of “diaspora” receives specific connotations when translated into Chinese that cannot account all the features of this community, thus in the Chinese academic discourse the substitution with the most important from the translator and editor's point of view equivalent (the situation “instead of diaspora”) is made.Conclusion. It is concluded that in Chinese, through translation, the author expresses important features of the migrant community, emphasising either its closeness, or its distance to the “diaspora” status.

Given its subject matter, biological psychiatry is uniquely poised to lead STEM DEI initiatives related to disability. Drawing on literatures in science, philosophy, psychiatry, and disability studies, we outline how that leadership might be undertaken. We first review existing opportunities for the advancement of DEI in biological psychiatry around axes of gender and race. We then explore the expansion of biological psychiatry’s DEI efforts to disability, especially along the lines of representation and access, community accountability, first person testimony, and (...) revised theoretical frameworks for pathology. We close with concrete recommendations for scholarship and practice going forward. By tackling head-on the challenge of disability inclusion, biological psychiatry has the opportunity to be a force of transformation in the biological sciences and beyond. (shrink)

Humans are complex systems, ‘macro-entities’, whose existence, behaviour and consciousness stem out of the configurations of physical entities on the micro-level of the physical world. But an explanation of what humans do and think cannot be found through ‘tracking us back’, so to speak, to micro-particles. So, in explaining human behaviour, including linguistic behaviour on which this paper focuses, emergentism opens up a powerful opportunity to explain what it is exactly that emerged on that level, bearing in mind the (...) end product in the form of the intra- and inter-cultural diversity. Currently there is a gap in emergentism research. On one hand, there are discussions in philosophy of the emergent human reality; on the other, there are discussions of social, cultural, or individual variation of these emergent aspects of humanity in the fields of anthropology, sociology, linguistics or psychology. What I do in this paper is look for a way to ‘trace’ some such diversified emergents from what is universal about their ‘coming to being’, all the way through to their diversification. My chosen emergent is human time, my domain of inquiry is natural-language discourse, and the drive behind this project is to understand the link between ‘real’ time of spacetime on the micro-level from which we emerged and the human time devised by us, paying close attention to the overwhelming diversity in which temporal reference is expressed in human languages. The main question is, where does this diversity fit in? Does understanding of this diversity, as well as of what lurks under the surface of this diversity, aid the emergentism story? My contribution to this volume on ‘the nature of structure and the structure of nature’ thus takes the following take on the title. The structure of human communication is at the same time uniform, universal, and relative to culture, in that it is emergent as a human characteristic, and as such compatible with the micro-level correlates in some essential ways, but also free to fly in different directions that are specific to societies and cultures. I explore here the grey area between the micro-level and the linguistic reflections of time—the middle ground that is emergent itself but that tends to be by-passed by those who approach the question of human flowing time from either end: metaphysics and the philosophy of time on the one hand, and contrastive linguistics, anthropological linguistics and language documentation on the other. I illustrate the debate with examples from tensed and tenseless languages from different language families, entertaining the possibility of a conceptual universal pertaining to time as degrees of epistemic modality. Needless to say, putting the question in this way also sets out my (not unassailable) methodology. (shrink)

This paper presents the design and validation process of a set of instruments to evaluate the impact of an informal learning initiative to promote Science, Technology, Engineering, and Mathematics vocations in students, their families, and teachers. The proposed set of instruments, beyond assessing the satisfaction of the public involved, allow collecting data to evaluate the impact in terms of changes in the consideration of the role of women in STEM areas and STEM vocations. The procedure followed to develop (...) the set of instruments consisted of two phases. In the first phase, a preliminary version of the questionnaires was designed based on the objectives of the Girls4STEM initiative, an inclusive project promoting STEM vocations between 6 and 18 years old boys and girls. Five specific questionnaires were designed, one for the families, two for the students and two for the teachers. A refined version of each questionnaire was obtained with evidence of content validity after undergoing an expert judgment process. The second phase was the refinement of the instruments, to ascertain the evidence of reliability and validity so that a final version was derived. In the paper, a high-quality set of good practices focused on promoting diversity and gender equality in the STEM sector are presented from a Higher Education Institution perspective, the University of Valencia. The main contribution of this work is the achievement of a set of instruments, rigorously designed for the evaluation of the implementation and effectiveness of a STEM promoting program, with sufficient validity evidence. Moreover, the proposed instruments can be a reference for the evaluation of other projects aimed at diversifying the STEM sector. (shrink)

Learning disabilities are highly prevalent on college campuses, yet students with learning disabilities graduate at lower rates than those without disabilities. Academic and psychosocial supports are essential for overcoming challenges and for improving postsecondary educational opportunities for students with learning disabilities. A holistic, multi-level model of campus-based supports was established to facilitate culture and practice changes at the institutional level, while concurrently bolstering mentors’ abilities to provide learning disability-knowledgeable support, and simultaneously creating opportunities for students’ personal and interpersonal development. Mixed (...) methods were used to investigate implementation of coordinated personal, interpersonal, and institutional level supports for undergraduate science, technology, engineering, and math (STEM) students with learning disabilities. A one-group pre-test post-test strategy was used to examine undergraduate outcomes. Participants included 52 STEM undergraduates with learning disabilities, 57 STEM graduate student mentors, 34 STEM faculty mentors, and 34 university administrators and personnel as members of a university-wide council. Enrolled for two years, undergraduates were engaged in group meetings involving psychoeducation and reflective discussions, development of self-advocacy projects, and individual mentorship. Undergraduates reported improved self efficacy (p =.001), campus connection (p <.001), professional development (p ≤.002), and self advocacy (p <.001) after two academic years. Graduate student mentors increased their understanding about learning disabilities and used their understanding to support both their mentees and other students they worked with. Council members identified and created opportunities for delivering learning disability-related trainings to faculty, mentors and advisors on campus, and for enhancing coordination of student services related to learning and related disorders. Disability-focused activities became integrated in broader campus activities regarding diversity. This research explicates a role that college campuses can play in fostering the wellbeing and the academic and career development of its students with developmental learning and related disorders. It offers an empirically tested campus-based model that is multilevel, holistic, and strengths-based for supporting positive outcomes of young people with learning disabilities in STEM. Moreover, findings advance the knowledge of supports and skills that are important for self-regulating and navigating complex and multi-faceted disability-related challenges within both the post-secondary educational environment and the young adults’ sociocultural context.

Recent developments in Western bioethics and biomedicine have called for the need to be culture-sensitive in handling certain bioethical issues. As a result of this anthropological turn in bioethics and biomedicine, there are cultural differences in moral attitudes such as disclosure of terminal illnesses, reproductive technologies, stem cell research, prenatal screening, genetic screening, therapeutic cloning, organ transplant, brain death, physician assisted suicide and so on.This paper offers an examination of the socio-culturally framed ways of dealing with Western and African (...) bioethics particularly as it relates to assisted reproductive technology. It focuses on the ethical issues surrounding assisted reproductive technology from an African perspective making special reference to their religious beliefs by drawing on the Christian and Islamic culture. Effort is made to distinguish between Western and African approaches to assisted reproduction stressing the fact of cultural diversity in issues relating to these reproductive techniques. It argues for the need to take social and cultural meanings embedded in various bioethical issues into consideration in arriving at different conclusions about issues in assisted reproduction in order to give room for adequate understanding.The paper concludes by emphasizing the need to acknowledge cultural diversity in bioethics giving reasons why this diversity is crucial and suggesting ways of handling this diversity.

ABSTRACTGiven its intimate relationship with the human body and its environment, biotechnology innovation, and more particularly stem cell research innovations as a part thereof, implicate diverse social and moral/ethical issues. This paper explores some of the most important and controversial moral concerns raised by human embryonic stem cell research , focusing on concerns relating to the wellbeing of the embryo and the wellbeing of society . It then considers how and whether these concerns are dealt with in regulatory (...) instruments in Argentina, a southern developing country, examining in particular whether the values underlying these concerns have been translated into practical and effective rules reflective of the primary moral positions advanced. It concludes that Argentina's current state of stem cell research governance fails to consistently reflect the moral positions that have formed and is inadequate given Argentina's activity in this field.

Human culture is uniquely complex compared to other species. This complexity stems from the accumulation of culture over time through high- and low-fidelity transmission and innovation. One possible reason for why humans retain and create culture, is our ability to modulate teaching strategies in order to foster learning and innovation. We argue that teaching is more diverse, flexible, and complex in humans than in other species. This particular characteristic of human teaching rather than teaching itself is one of the reasons (...) for human’s incredible capacity for cumulative culture. That is, humans unlike other species can signal to learners whether the information they are teaching can or cannot be modified. As a result teaching in humans can be used to support high or low fidelity transmission, innovation, and ultimately, cumulative culture. (shrink)

This book takes as its point of departure a humble cell lying on the intersection of ideas as diverse and yet interlaced as life, knowledge, commerce, governance, and ethics. It seeks to deepen the understanding of stem cell entities and the concerns, hopes, and aspirations that shape and make them viable therapeutic entities in the context of rapid globalization. Several key intersections between individual, group, and institutional relationships have become central to locating and debating the production of stem (...) cells today. This edited collection addresses three overarching concerns: regenerating the notion of ethics, the emerging therapeutic horizons, and the position of the patient. As a whole this book seeks to explain how stem cells are accommodated, contested, and used in contemporary India and around the globe through an informed unpacking of issues underpinning contestation and promotion bestriding these technological developments. The authors offer a truly multi-disciplinary perspective, stimulating conversation between the social sciences, biological sciences and the patient. The concerns expressed and highlighted by these conversations are embedded in a vast geo-political expanse stretching from India to Euro-America and will be of great interest to academics and practitioners across fields including science technology studies, medicine and international development.

Despite efforts to foster gender equality in academia, women are vastly under-represented in tenured professorships, specifically in STEM disciplines. While previous research investigated structural and organizational barriers for women in academia, we explored professors’ subjective view on attributes required before and after reaching tenure. The perspective of professors is needed as they are gatekeepers when it comes to the career advancement of junior researchers. Hence, we interviewed 25 tenured STEM professors in Germany about which attributes they personally consider (...) to be required pre- versus post-tenure and analyzed whether these attributes are associated with gender stereotypes. We found that different attributes are mentioned in the pre- versus the post-tenure career stage and that the required attributes can be associated with gender stereotypes: While agentic–stereotypically male–attributes were mentioned more frequently than communal attributes in the pre-tenure career stage, communal–stereotypically female–attributes were reported slightly more often than agentic attributes after reaching tenure. Based on these novel findings, we discuss important implications for gender research and practice to contribute to more diversity and transparency in academic career advancement. (shrink)

In recent years, there has been a proliferation of studies of international justice. This book is a valuable contribution to that trend. Tan presents his theory as a rival to Rawls’s “law of peoples”. He argues that his critique of Rawls’s work on international justice points to deep flaws in Rawls’s general account of justice and not merely to a mistaken application in a particular area. Specifically, Tan claims that the core fault of the law of peoples is its neglect (...) of individual liberty and that this neglect “stems ultimately from political liberalism’s mistaken stress on toleration as the fundamental liberal principle”. Tan argues that comprehensive liberalism is superior to political liberalism because it takes “individual autonomy to be fundamental”. (shrink)

Development and maintenance of diverse organ systems require context‐specific regulation of stem cell behaviour. We hypothesize that this is achieved via reciprocal regulation between the cell cycle machinery and differentiation factors. This idea is supported by the parallel evolutionary emergence of differentiation pathways, cell cycle components and complex multicellularity. In addition, the activities of different cell cycle phases have been found to bias cells towards stem cell maintenance or differentiation. Finally, several direct mechanistic links between these two processes (...) have been established. Here, we focus on interactions between cyclin‐CDK complexes and differentiation regulators of the Notch pathway and Sox family of transcription factors within the context of pluripotent and neural stem cells. Thus, this hypothesis formalizes the links between these two processes as an integrated network. Since such factors are common to all stem cells, better understanding their interconnections will help to explain their behaviour in health and disease. (shrink)

As a sort of intellectual provocation and as a lateral thinking strategy for creativity, this chapter seeks to determine what the study of the dynamics of biodiversity can offer linguists. In recent years, the analogical equation "language = biological species" has become more widespread as a metaphorical source for conceptual renovation, and, at the same time, as a justification for the defense of language diversity. Language diversity would be protected in a way similar to the mobilization that has (...) taken place to protect endangered species. Nevertheless, one must be careful when uncritically transferring conceptualizations and theoretical frameworks from one field to another, since obviously, these two phenomena are quite different in the real world. The dialogue with bioecologists starts by asking about the formation of diversity, i.e., about specialization. Here, one can observe the similarity between the processes of linguistic and genetic fragmentation, in the sense that both phenomena have a (socio)geographical basis for dispersion and consequently, for the loss of their original compact nature and their intercommunication. The self-organizing and creative properties of human beings favor the development of specific varieties for each subset, varieties that continue to evolve constantly, through the unceasing "languaging" of humanity. Regarding the continuity of species or languages, one can also observe the decisive role of intragroup relations. The staying power of linguistic varieties will increase in direct proportion to the intensity of the relationship among the components of the subset. On the other hand, if exotic elements are introduced, especially if these elements are aggressive in nature, the alteration of the ecological niche may turn out to be fatal for the continuity of the previously existing forms. This suggests to us the need to make an in-depth study of what the minimal contextual conditions would be so that a set linguistic group could be assured a sustainable continuity within a framework of linguistic contact. What type of minimum (socio-)ecological niche would a language have to have if we wished to ensure its habitual reproduction? A proposal is made here to explore the ideas of "exclusive functions" and "non-hierarchical functional distribution" for codes in situations where there is high contact and a danger of disuse. As regards change, this phenomenon is seen as an inherent element in the tendency of life to create new developments, which may or not be accompanied by an adaptation to changing environmental conditions. It is pointed out that, similar to what happens in biology, much of linguistic innovation stems from a systemically reorganized mixture of solutions from different codes. An important research question would be, however, to determine why some of these innovations disappear and others survive and extend throughout the community. The big question mark, as Mufwene points out, is, then how to manage to understand how "the evolution of language proceeds by naturally selecting from among the competing alternatives available through the idiolects of individual speakers". Extinction, whether it be of languages or of species, is caused in most cases "by a combination of demographic processes and environmental changes", as Brown points out. Thus, the environment plays a fundamental role in the direction of evolution, since the "the survival of the fittest is, in actuality, the survival of those who fit into the context (Allen and Hoekstra)". This allows us to see the great degree of importance of political-economic contexts in the case of languages. In the same way, migratory movements are also one of the major variables determining the extinction of biodiversity and language diversity. Species and habitat form the basic unit of existence, and this is the major point of departure for understanding the problem of the preservation and recovery of species or languages. Given the increase in the degree of linguistic contact, the continuity of language diversity depends on determining, as exactly as possible, as Prigogine, the physicist, would say, what precise conditions of imbalance may prove to be stable. The great challenge is not so much avoiding contact but managing it. And "restorative ecology" can also be of help to us here. Being able to reach sustainable solutions for language diversity implies a profound knowledge of the dynamics for determining the ways in which language is used in contact situations. The general conclusion is that linguistics is still terminologically and conceptually ill prepared to deal with the dynamic character of human languages. The world and our objects must be conceived of as elements in a state of flux, as changing systems in an unstable equilibrium. With respect to language policy, it would be necessary to make an effort to manage to establish some general principles regarding the linguistic organization of the human species that would make it possible for local linguistic diversity and communication on a planetary scale, which must necessarily take place, to be compatible with each other. To succeed, it will be necessary to continue promoting an autonomous socio-ecological perspective devoted to the comprehension of language phenomena. Such a perspective would be based on a paradigm of complexity, and would, at the same time, place human beings at the center of its theoretical underpinnings. (shrink)

The history and context of the public policy regarding stem cell research in the European Union are complex. The regulations respond to and aim to realize political and economic goals across a large region that is culturally diverse, as well as addressing moral judgments on a contested emerging area of research. This history and context are relevant for the arguments developed here in relation to autologous stem cell research and how it is affected by those regulations.The EU is (...) currently an open market across 28 countries with different languages as well as varied cultural, religious, and political histories. Bridging the diverse traditions and their corresponding local policies and regulations is often a... (shrink)

Cognitive diversity is an important concept stemming from western management research in the 1990s. With the rapid development of science and technology, there is a growing interest in the composition of an academic research team, such as team diversity. However, there is no tool available for measuring team cognitive diversity for academic research teams. Based on Van der Vegt’s theoretical model of TCD, an Academic Research Team Cognitive Diversity Scale is developed and validated for an academic (...) research team in our research with two studies. In Study One, in-depth interviews and panel discussions were conducted to generate a preliminary questionnaire. In Study Two, the questionnaire was administered among academic research teams. Exploratory factor analysis revealed four factors regarding cognitive diversity: the way of thinking, knowledge and skills, the view of the world, and beliefs about what is right and wrong. The factor structure was further validated by confirmatory factor analysis. Moreover, correlation and regression analyses showed that academic research TCD was positively related to team creativity and performance. To sum up, our newly developed 15-item ATCDS is sufficiently reliable and valid to be used for understanding cognitive diversity among academic research teams. (shrink)

Emerging evidence suggests that microRNA (miRNA)‐mediated post‐transcriptional gene regulation plays an essential role in modulating embryonic stem (ES) cell pluripotency maintenance, differentiation, and reprogramming of somatic cells to an ES cell‐like state. Investigations from ES cell‐enriched miRNAs, such as mouse miR‐290 cluster and human miR‐302 cluster, and ES cell‐depleted miRNAs such as let‐7 family miRNAs, revealed a common theme that miRNAs target diverse cellular processes including cell cycle regulators, signaling pathway effectors, transcription factors, and epigenetic modifiers and shape their (...) protein output. The combinatorial effects downstream of miRNA action allow miRNAs to modulate cell‐fate decisions effectively. Furthermore, the transcription and biogenesis of miRNAs are also tightly regulated. Thus, elucidating the interplay between miRNAs and other modes of gene regulation will shed new light on the biology of pluripotent stem cells and somatic cell reprogramming. (shrink)

Bioethical debates on the use of human embryos and oocytes for stem cell research have often been criticized for the lack of empirical insights into the perceptions and experiences of the women and couples who are asked to donate these tissues in the IVF clinic. Empirical studies that have investigated the attitudes of IVF patients and citizens on the donation of their embryos and oocytes have been scarce and have focused predominantly on the situation in Europe and Australia. This (...) article examines the viewpoints on the donation of embryos for stem cell research among IVF patients and students in China. Research into the perceptions of patients is based on in-depth interviews with IVF patients and IVF clinicians. Research into the attitudes of students is based on a quantitative survey study. The empirical findings in this paper indicate that perceptions of the donation of human embryos for stem cell research in China are far more diverse and complex than has commonly been suggested. Claims that ethical concerns regarding the donation and use of embryos and oocytes for stem cell research are typical for Western societies but absent in China cannot be upheld. The article shows that research into the situated perceptions and cultural specificities of human tissue donation can play a crucial role in the deconstruction of politicized bioethical argumentation and the assumptions about “others” that underlie socio-ethical debates on the moral dilemmas of technology developments in the life sciences.

Understanding the intersections of science and publics has led to research on how diverse publics interpret scientific information and form positions on science-related issues. Research demonstrates that attitudes toward science, political and religious orientation, and other social factors affect adult interactions with science, which has implications for how adults influence K-12 STEM (science, technology, engineering, and mathematics) education. Based on a statewide survey of adults in Idaho (n = 407), a politically and religiously conservative western state, we demonstrate how (...) attitudes toward science, measured through a composite measure “orientation toward science,” and other social factors are correlated with support for STEM education. Results show that “orientation toward science,” along with political orientation and respondents’ perceptions of feeling informed about science, predicts behavior intentions to support STEM education. Our findings suggest that a nuanced and localized approach to fostering support for K-12 STEM education would resonate with populations regardless of political orientation, and they illuminate new ways of thinking about how political orientation more generally impacts thinking about science in the context of complicated “socio-scientific relations.” In exploring how people think about science in a politically and religiously conservative state, we provide insights on potential outcomes in other states, should conservative ideology spread. We argue that the publics’ relationship with science and, by extension, support for science education, is more fluid, as many of us suspect, than ideological polemics suggest. (shrink)

Over the past 50 years the diversity of higher education faculty in the mathematical, physical, computer, and engineering sciences has advanced very little at 4-year universities in the United States. This is despite laws and policies such as affirmative action, interventions by universities, and enormous financial investment by federal agencies to diversify science, technology, mathematics, and engineering career pathways into academia. Data comparing the fraction of underrepresented minority postdoctoral scholars to the fraction of faculty at these institutions offer a (...) straightforward empirical explanation for this state of affairs. URM postdoc appointments lag significantly behind progress in terms of both undergraduate and Ph.D.-level STEM student populations. Indeed, URM postdoc appointments lag well-behind faculty diversity itself in the MPCES fields, most of which draw their faculty heavily from the postdoctoral ranks, particularly at research-intensive universities. Thus, a sea-change in how postdocs are recruited, how their careers are developed, and how they are identified as potential faculty is required in order to diversify the nation’s faculty, and particularly the R1 MPCES professoriate. Our research shows that both Ph.D. students and postdocs benefit from intentional structure at various levels of their respective “apprentice” experiences, a factor that we believe has been neglected. Several key structural approaches are highly effective in these regards: A collaborative approach in which leading research universities collectively identify outstanding URM candidates; Faculty engagement in recruiting and supporting these postdocs; Inter-institutional exchange programs to heighten the visibility and broaden the professional experiences of these postdocs; Community-building activities that create a sense of belonging and encourage continuing in academia for each cohort; and Continuing research based on outcomes and new experimental approaches. The California Alliance, consisting of UC Berkeley, UCLA, Caltech, and Stanford, has been engaged in such a program for almost a decade now, with most of the California Alliance URM postdocs now in tenure track positions or on the path toward careers as faculty at research intensive institutions. If this approach was brought to scale by involving the top 25 or so URM Ph.D.-producing R1 institutions in the MPCES fields, about 40% of the national URM postdoctoral population in these fields could be affected. Although this impact would fall short of bringing URM MPCES faculty ranks up to full representation of the United States population as a whole, it would vastly improve the outlook for URM students and their aspirations to take on leadership roles as scientists and engineers.

In history, many conflicts have occurred in understanding and interpretation of the verses of the Qur'an. When details come up and when the opinions about the content of the subject are put forward, more conflicts occur in the interpretation of a verse even when it seems to be clear a first glance. Facts such as to whom the verse addresses, who is meant by the verse, in which time the verse has been descended and the situations revealed by the verse, (...) whether it has the same validity for everyone causes the deepening of the difference. While these conflicts sometimes bring diversity in interpretation, sometimes there may be opinions that cannot be reconciled with each other, which are quite disconnected from each other and reject each other radically. In the interpretation of the verse “There is None of You Who Will Not Pass Over It”, many different views have been put forward about who is meant in the verse, what the nature of the entry into hell is and who is within the scope of this verse. In the integrity of the Qur'an, the commentators have resorted to some evidence to solve the issue of how to locate the interpretation of this verse. Some said that this verse was only directed towards the disbelievers. Some have said that this verse is covering everyone, but the entry of believers to hell is a temporary entry and does not have the purpose of punishment. This study aims to reveal the conflicts that have arisen about the interpretation of the verse “There is None of You Who Will Not Pass Over It” (Wa In Minkum İllā Wāriduhā) and to evaluate these conflicts in the context of the semantic analysis of the verb w-r-d. Therefore, first of all, the etymological structure of the verb w-r-d was examined and the dictionary meaning of the word was revealed. Then, in order to determine the meaning of this word before the revelation, the meanings of this verb root in the poems of Jahiliyyah were tried to be determined. Then, the places where this verb stem is used in the Qurʾān are examined and the meanings in the contexts are pointed out. As the next step, the disagreements that have come up to date regarding the interpretation of the verse “There is None of You Who Will Not Pass Over” have been put forward. These conflicts have been addressed by frequently applying to the classical and modern tafsīr studies written until today, starting from the tafsir narrations from the first interlocutors of the Qurʾān. Further, these conflicts have been tried to be presented by classifying them within themselves. Subsequently, it has been tried to contribute to the interpretation of the verse by considering the data obtained from the semantic analysis of the verb w-r-d. Finally, the issue of why this verb root was preferred in this verse, which mentions that all people will go to hell without exception, has been discussed. (shrink)

: National bioethics commissions have struggled to develop ethically warranted methods for conducting their deliberations. The National Bioethics Advisory Commission in its report on stem cell research adopted an approach to public deliberation indebted to Rawls in that it sought common ground consistent with shared values and beliefs at the foundation of a well-ordered democracy. In contrast, although the research cloning and stem cell research reports of the President's Council on Bioethics reveal that it broached two different methods (...) of public deliberation—balancing goods and following an overarching moral principle—it adopted neither. Thereupon its prime mover, Leon Kass, influenced particularly by the approach of Leo Strauss, sought to develop a method of public deliberation guided by tradition and practical wisdom. When this failed, the Council fell back on a method that took account of shared fundamental values of a free democracy—a method remarkably akin to that employed by the National Bioethics Advisory Commission. Respect for diverse reasonable conceptions of the good in a democratic polity requires national bioethics commissions to seek and incorporate that which is valuable in opposing positions. (shrink)

In their landmark 2010 paper, “The weirdest people in the world?”, Henrich, Heine, and Norenzayan outlined a serious methodological problem for the psychological and behavioural sciences. Most of the studies produced in the field use people from Western, Educated, Industrialised, Rich and Democratic (WEIRD) societies, yet inferences are often drawn to the species as a whole. In drawing such inferences, researchers implicitly assume that either there is little variation across human populations, or that WEIRD populations are generally representative of the (...) species. Yet neither of these assumptions is justified. In many psychological and behavioural domains, cultural variation begets cognitive variation, and WEIRD samples are recurrently shown to be outliers. In the years since the article was published, attention has focused on the implications this has for research on extant human populations. Here we extend those implications to the study of ancient _H. sapiens_, their hominin forebears, and cousin lineages. We assess a range of characteristic arguments and key studies in the cognitive archaeology literature, identifying issues stemming from the problem of sample diversity. We then look at how worrying the problem is, and consider some conditions under which inferences to ancient populations via cognitive models might be provisionally justified. (shrink)

The mouthparts of anuran tadpoles are highly derived compared to those of caecilians or salamanders. The suprarostral cartilages support the tadpole's upper beak; the infrarostral cartilages support the lower beak. Both supra‐ and infrarostral cartilages are absent in other vertebrates. These differences reflect the evolutionary origin of a derived feeding mode in anuran tadpoles. We suggest that these unique cartilages stem from the evolution of new articulations within preexisting cartilages, rather than novel cartilage condensations. We propose testing this hypothesis (...) through a search for similarities in the development of the suprarostral and infrarostral cartilage articulations and of the primary jaw joint. In Xenopus, the gene zax is expressed in a region corresponding to the infrarostral cartilage. This gene is related to the bapx1‐gene, which regulates jaw joint development. Further investigation of these genes, as well as other genes with joint‐related functions, in anuran craniofacial development may provide a connection between the morphological diversity seen in the vertebrate head and the corresponding diversity in genetic regulatory processes. We believe that the evolution of larval jaws in anurans may shed light on the general evolutionary mechanisms of how new articulations, not only in the jaw region, could have arisen in the vertebrate skull.

Studies of education and careers in science, technology, engineering, and math commonly use a pipeline metaphor to conceptualize forward movement and persistence. However, the “STEM pipeline” carries implicit assumptions regarding length, contents, and perceived purpose. Using the National Survey of College Graduates, we empirically measure each of these dimensions. First, we show that a majority of STEM workers report skills training throughout their careers, suggesting no clear demarcation between education and work. Second, we show that using on-the-job expertise (...) requirements paints a very different portrait of the STEM workforce—and persistence in it. Third, we show that STEM-educated workers are well-prepared for but dissatisfied with non-STEM jobs, complicating our understanding of leaving. Collectively, these results recommend expanded conceptions of STEM education and careers and contribute to studies of science and engineering workforce transitions and diversity. (shrink)
