The year 2018 was the 40th anniversary of the birth of Louise Joy Brown, marking four decades of clinical in vitro fertilization and embryo transfer. Though this milestone, reached first by Steptoe and Edwards in the United Kingdom, is well acknowledged through Nobel accolade, the achievement was not entirely celebrated at the time. Global contention was not just moral, but political and legislative. In the United States, the achievement led in 1978 to the freezing of federal funds by the National (...)

The development of the Functional Genomics Investigation Ontology (FuGO) is a collaborative, international effort that will provide a resource for annotating functional genomics investigations, including the study design, protocols and instrumentation used, the data generated and the types of analysis performed on the data. FuGO will contain both terms that are universal to all functional genomics investigations and those that are domain specific. In this way, the ontology will serve as the “semantic glue” to provide a common understanding of data (...) from across these disparate data sources. In addition, FuGO will reference out to existing mature ontologies to avoid the need to duplicate these resources, and will do so in such a way as to enable their ease of use in annotation. This project is in the early stages of development; the paper will describe efforts to initiate the project, the scope and organization of the project, the work accomplished to date, and the challenges encountered, as well as future plans.

Bone marrow is the main site for hematopoiesis in adults. It acts as a niche for hematopoietic stem cells (HSCs) and contains non‐hematopoietic cells that contribute to stem cell dormancy, quiescence, self‐renewal, and differentiation. HSC also exist in resting spleen of several species, although their contribution to hematopoiesis under steady‐state conditions is unknown. The spleen can however undergo extramedullary hematopoiesis (EMH) triggered by physiological stress or disease. With the loss of bone marrow niches in aging and disease, the spleen as (...) an alternative tissue site for hematopoiesis is an important consideration for future therapy, particularly during HSC transplantation. In terms of harnessing the spleen as a site for hematopoiesis, here the remarkable regenerative capacity of the spleen is considered with a view to forming additional or ectopic spleen tissue through cell engraftment. Studies in mice indicate the potential for such grafts to support the influx of hematopoietic cells leading to the development of normal spleen architecture. An important goal will be the formation of functional ectopic spleen tissue as an aid to hematopoietic recovery following clinical treatments that impact bone marrow. For example, expansion or replacement of niches could be considered where myeloablation ahead of HSC transplantation compromises treatment outcomes. (shrink)

Trait emotional intelligence concerns people’s perceptions of their emotional functioning. Two studies investigated this construct in surgeons and comparison occupations. We hypothesized that trait EI profiles would differ both within surgical specialties as well as between them and other professions. Study 1 compared the trait EI profiles of four different surgical specialties. There were no significant differences amongst these specialties or between consultant surgeons and trainees in these specialties. Accordingly, the surgical data were combined into a single target sample that (...) was compared against samples of engineers, executives and senior managers, lawyers, junior military managers, nurses, and salespeople. Surgeons scored significantly higher on global trait EI than junior military managers, but lower than executives and senior managers, salespeople, and nurses. There were no significant differences vis-à-vis engineers or lawyers. A MANOVA confirmed a similar pattern of differences in the four trait EI factors. Global trait EI scores correlated strongly with single-question measures of job satisfaction and job performance in the surgical sample. These findings suggest that interventions to optimize the trait EI profiles of surgeons can be helpful in relation to job satisfaction, job performance, and overall psychological wellbeing. (shrink)

The ectoplasmic specialization (ES) is a testis‐specific, actin‐based hybrid anchoring and tight junction. It is confined to the interface between Sertoli cells at the blood–testis barrier, known as the basal ES, as well as between Sertoli cells and developing spermatids designated the apical ES. The ES shares features of adherens junctions, tight junctions and focal contacts. By adopting the best features of each junction type, this hybrid nature of ES facilitates the extensive junction‐restructuring events in the seminiferous epithelium during spermatogenesis. (...) For instance, the α6β1‐integrin–laminin 333 complex, which is usually limited to the cell–matrix interface in other epithelia to facilitate cell movement, is a putative apical ES constituent. Furthermore, JAM‐C and CAR, two tight junction integral membrane proteins, are also components of apical ES involving in spermatid orientation. We discuss herein the mechanisms that maintain the cross‐talk between ES and blood–testis barrier to facilitate cell movement and orientation in the seminiferous epithelium.

We reflect, using a vignette, on conceptual tensions and the value judgements that lie behind difficult decisions about whether or not the older person with dementia should return home or move into long-term care following hospital admission. The paper seeks, first, to expose some of the difficulties arising from the assessment of residence capacity, particularly around the nature of evaluative judgements and conceptual tensions inherent in the legal approach to capacity. Secondly, we consider the assessment of best interests around place (...) of residence, which demonstrates significant conceptual tensions. In addition, ‘best interests’ raise issues around the perception of risk and the perceptions of the family and crucially involve the notions of autonomy and trust. Finally, we not only gesture at some practical considerations based on insights from values-based medicine, but also make the suggestion that we require tighter functional assessments of residence capacity coupled with broader judgements about best interests.

Spatial Practices makes a timely and significant contribution to the growing literature on social/spatial theory. In it the notion of spacial practice takes on a rich and layered meaning for some of America's leading scholars as they critically link the theoretical practices of the space of their disciplines to the practical social space of everyday political and economic urban life. Original essays provide compelling insights into the space of racial politics, the unavoidability of recognizing a radical planning practice, and the (...) imagistic face of the contemporary "figured" city. The reader will find rich conceptual tools presented in discussions that grapple with issues raised by the production of reduced public space in common interest developments and the ubiquitous mall, the ideologies of economic restructuring, the rhetorical politics of urban revitalization, and the analytic potential of the photo/text. Students and scholars interested in how spatial theory has enriched and renewed urban theory will find Spatial Practices invaluable. It will be useful in a wide range of classes across disciplines including urban studies, urban planning, architecture, political science, sociology, geography, economics, and policy studies. "This collection explores the exciting analytical edge where investigations of urban political economy converge with cultural studies. In their exploration of theory and practice as they relate to the production of space, the authors cover a dazzling range of topics. Yet despite their varying preoccupations, the essays merge into a unified inquiry that reveals the functions and meanings of contemporary spatial forms. All those who are interested in the forces shaping urban and regional development, as well as in the impact of space on social relations, must read this book. (shrink)

In 1989 Smart problematised law as a masculinist knowledge which disqualified other forms of knowledge, particularly feminism. Twenty-one years later Smart characterises the relationship between law and feminism quite differently. In this account law responds to feminism and outcomes are progressive. Smart suggests that rather than continuing to focus on law’s disciplinary and normalising role, it is more productive to conceptualise contemporary family law as a creative kinning practice. We argue, however, that we must also bring into this account the (...) changes to the state brought about by neo-liberalism. The paper tests these observations about the trajectories of feminism, law and neo-liberalism by reflecting upon our study of the Albert Kennedy Trust (AKT). AKT was established in 1989, in the wake of gay and lesbian resistance to Clause 28, to provide homes with gay and lesbian adults for homeless gay and lesbian teenagers. We are interested in AKT’s shift in its description of the adults’ relationship with the teenagers in their care from ‘brothers and sisters’ to ‘carers’ as it moved from a marginal force to mainstream partner/provider. In this context we explore the complexity of law’s responsiveness to feminism’s dynamism, its contingent recognition of kinning practices and, in the light of neo-liberalism, its continuing disciplinary role.

Scientific pluralism is an issue at the forefront of philosophy of science. This landmark work addresses the question, Can pluralism be advanced as a general, philosophical interpretation of science?

Scientific pluralism is an issue at the forefront of philosophy of science. This landmark work addresses the question, Can pluralism be advanced as a general, philosophical interpretation of science? Scientific Pluralism demonstrates the viability of the view that some phenomena require multiple accounts. Pluralists observe that scientists present various—sometimes even incompatible—models of the world and argue that this is due to the complexity of the world and representational limitations. Including investigations in biology, physics, economics, psychology, and mathematics, this work provides (...) an empirical basis for a consistent stance on pluralism and makes the case that it should change the ways that philosophers, historians, and social scientists analyze scientific knowledge.

ABSTRACTDifficulties with inhibiting fear have been associated with the emergence of anxiety problems and poor response to cognitive–behavioural treatment. Fear inhibition problems measured using experimental paradigms involving aversive stimuli may be inappropriate for vulnerable samples and may not capture fear inhibition problems evident in everyday life. We present the Fear Inhibition Questionnaire, a self-report measure of fear inhibition abilities. We assess the FIQ’s factor structure across two cultures and how well it correlates with fear inhibition indices derived experimentally. Adolescent participants (...) from Hong Kong and England completed the FIQ, with the English participants also completing a conditioning and extinction task to assess fear inhibition problems. Across both cultures, the FIQ showed a single factor structure and low FIQ scores, or worse fear inhibition problems, were associated with self-reports of heightened anxiety. Correlation of FIQ scores with experimental indices, whi... (shrink)

This essay introduces the volume Scientific Pluralism (Volume 19 of Minnesota Studies in Philosophy of Science). Varieties of recent pluralisms are surveyed, the difference between monism and pluralism vis a vis the sciences is clarified, and the authors’ notion of scientific pluralism is advanced.

ABSTRACT This cross-sectional study compared the moral reasoning of first-year and third-year doctoral students in clinical psychology. Nineteen first-year and 20 third-year students were recruited from 17 doctoral training programs in the UK. Most adopted a sophisticated approach to moral judgments, as assessed by the Defining Issues Test, although, surprisingly, more experienced students had significantly less sophisticated schemata. In their moral judgments, less experienced students relied more heavily on their personal, and more experienced students on their professional, constructs, as assessed (...) by repertory grid technique. Integration between personal and professional constructs was higher in more experienced students. (shrink)
