This book tackles the most difficult and profound open questions about life and its origins from an information-based perspective.

Over the past decade, the number of clinical trials registered with the Food and Drug Administration has increased dramatically. The business of clinical research has become more diverse, involving academic institutions, clinician-researchers in community settings, pharmaceutical companies, and contract research organizations. This growth has been accompanied by increasing concerns about the ethical conduct of research. Much of this concern has been directed to procedural issues including institutional review board review, data monitoring, and informed consent forms. However, the protection of human (...) subjects cannot be achieved by relying solely on procedural safeguards. There are more nuanced issues related to recruitment and retention of subjects, and to the process of informed consent, that are generated during the interaction between study staff and subjects. It is only through an examination of these relationships that one can more fully define and understand the challenges of protecting subjects in research. (shrink)

Patient-derived xenografts are currently promoted as new translational models in precision oncology. PDXs are immunodeficient mice with human tumors that are used as surrogate models to represent specific types of cancer. By accounting for the genetic heterogeneity of cancer tumors, PDXs are hoped to provide more clinically relevant results in preclinical research. Further, in the function of so-called “mouse avatars”, PDXs are hoped to allow for patient-specific drug testing in real-time. This paper examines the circulation of knowledge and bodily material (...) across the species boundary of human and personalized mouse model, historically as well as in contemporary practices. PDXs raise interesting questions about the relation between animal model and human patient, and about the capacity of hybrid or interspecies models to close existing translational gaps. We highlight that the translational potential of PDXs not only depends on representational matching of model and target, but also on temporal alignment between model development and practical uses. Aside from the importance of ensuring temporal stability of human tumors in a murine body, the mouse avatar concept rests on the possibility of aligning the temporal horizons of the clinic and the lab. We examine strategies to address temporal challenges, including cryopreservation and biobanking, as well as attempts to speed up translation through modification and use of faster developing organisms. We discuss how featured model virtues change with precision oncology, and contend that temporality is a model feature that deserves more philosophical attention. (shrink)

Workplace ostracism is a prevalent and painful experience. The majority of studies focus on negative outcomes of ostracism, with less work examining employees’ potential adaptive responses to it. Further, scholars have suggested that such responses depend on employee attributions, yet little research has taken an attributional perspective on workplace ostracism. Drawing on sociometer theory and attribution theory we develop and test a model that investigates why and under what circumstances ostracized employees engage in adaptive responses to ostracism. Specifically, we argue (...) that ostracized employees feel greater levels of shame and, in turn, are motivated to engage in greater ingratiation behavior toward their ostracizers. However, we predict that perceptions of ostracizers’ competence and warmth shape different attributional processes, which influence the degree to which the ostracized employee experience shame and, in turn, is motivated to engage in ingratiation behavior. Results of a three-wave, time-lagged survey support our prediction that shame mediates the relationship between coworker ostracism and ingratiation behavior. Moreover, results support our three-way interaction, such that coworkers who report higher levels of ostracism and who perceive their coworkers as more (vs. less) competent and more (vs. less) warm report higher shame, and, in turn, ingratiation behavior. Theoretical and practical implications, as well as avenues for future research, are discussed. (shrink)

The essays collected in this issue offer complementary critical perspectives on the mature lyric work of Derek Walcott, the acclaimed Nobel laureate from the Caribbean island of St. Lucia. The centerpiece of the ensemble is a previously unpublished essay in which Walcott’s reflections on poetics illuminate his project in the masterpiece, _Omeros._ Other contributions by literary scholars in North America and the Caribbean focus on fundamental dimensions of Walcott’s craft and on such thematic preoccupations as the intersection of pictorial and (...) verbal modes of representation, the deployment of nuanced intertextual strategies (especially in relation to the Greco-Roman canon), the invention of a viable artistic identity in a postcolonial intercultural milieu, and the psychosocial modeling of the process of literary apprenticeship. _Contributors. _Edward Baugh, Peter Burian, Gregson Davis, Carol Dougherty, Joseph Farrell, Judith Harris, Timothy Hofmeister, Derek Walcott.

In order to reduce the dimensionality of parameter space and enhance out-of-sample forecasting performance, this research compares regularization techniques with Autometrics in time-series modeling. We mainly focus on comparing weighted lag adaptive LASSO with Autometrics, but as a benchmark, we estimate other popular regularization methods LASSO, AdaLASSO, SCAD, and MCP. For analytical comparison, we implement Monte Carlo simulation and assess the performance of these techniques in terms of out-of-sample Root Mean Square Error, Gauge, and Potency. The comparison is assessed with (...) varying autocorrelation coefficients and sample sizes. The simulation experiment indicates that, compared to Autometrics and other regularization approaches, the WLAdaLASSO outperforms the others in covariate selection and forecasting, especially when there is a greater linear dependency between predictors. In contrast, the computational efficiency of Autometrics decreases with a strong linear dependency between predictors. However, under the large sample and weak linear dependency between predictors, the Autometrics potency ⟶ 1 and gauge ⟶ α. In contrast, LASSO, AdaLASSO, SCAD, and MCP select more covariates and possess higher RMSE than Autometrics and WLAdaLASSO. To compare the considered techniques, we made the Generalized Unidentified Model for covariate selection and out-of-sample forecasting for the trade balance of Pakistan. We train the model on 1985–2015 observations and 2016–2020 observations as test data for the out-of-sample forecast. (shrink)

In this special issue of Human Nature we explore the possible adaptive links between teaching and learning during childhood, and we aim to expand the dialogue on the ways in which the social sciences, and in particular current anthropological research, may better inform our shifting understanding of how these processes vary in different social and ecological environments. Despite the cross-disciplinary trend toward incorporating more behavioral and cognitive data outside of postindustrial state societies, much of the published cross-cultural data is presented (...) as stand-alone population-level studies, making it challenging to extrapolate trends or incorporate both ecological and developmental perspectives. Here, contributors explore how human life history, ecological experience, cumulative culture, and ethnolinguistics impact social learning and child development in foraging and transitioning societies around the world. Using historical ethnographic data and qualitative and quantitative data from studies with contemporary populations, authors interrogate the array of factors that likely interact with cognitive development and learning. They provide contributions that explore the unique environmental, social, and cultural conditions that characterize such populations, offering key insights into processes of social learning, adaptive learning responses, and culture change. This series of articles demonstrates that children are taught culturally and environmentally salient skills in myriad ways, ranging from institutionalized instruction to brief, nuanced, and indirect instruction. Our hope is that this collection stimulates more research on the evolutionary and developmental implications associated with teaching and learning among humans. (shrink)

In this introduction to part 2 of the Common Knowledge symposium “Peace by Other Means,” the journal's editor reflects on the difference between the contributions to parts 1 and 2. Whereas the first installment concentrated on ethnography, the second focuses on the peacemaking repertoire of the Greco-Latin tradition, whose basis is psychological. That tradition is characterized by its refusal of wishful thinking about human nature and, in particular, by its doubt about claims that human drives other than thumos — the (...) rage for self-aggrandizement — motivate the initiators of wars. Given this assumption about motive, the Greco-Latin tradition tends also to regard negotiations based on the rational discussion of material interests as unlikely to succeed. Success requires symbolic and ritual gestures — acts of self-humiliation on the part of those apparently with the greatest power — by which thumos is propitiated and pacified. Most of the introduction considers cases of such settlements, including two contemporary efforts at ritual peacemaking, a successful one by Queen Elizabeth II in Ireland and an unsuccessful one by Pope Francis in the Middle East.

What differentiates expressions of pain from other facial expressions? Which facial features convey the most information in an expression of pain? To answer such questions we can explore the expertise of human observers using psychophysical experiments. Techniques such as change detection and visual search can advance our understanding of facial expressions of pain and of evolved mechanisms for detecting these expressions.

Pediatric residents experience ethical dilemmas and moral distress during training. Few studies have identified meaningful methods in reducing moral distress in pediatric trainees. The authors aimed to determine how residents perceive ethics case discussions, whether such a program affects trainee ethics knowledge and perceived moral distress, and if residents’ perceived moral distress changes before, during, and after a discussion series. Participants included pediatric residents in a single residency program. Five separate 1-hour sessions were presented over a 5-month period. Each session (...) consisted of a case presentation by a resident developed under the guidance of an ethicist. Multidisciplinary services and content experts were present during sessions. Baseline, postsession, and final surveys were distributed to resident attendees. Open-ended responses were recorded. When comparing baseline and final responses, the only significance was increased preparedness to navigate ethical decisions (p = 0.004). A 10.2% decline was observed in perceived moral distress. An increase in ethics knowledge was observed. Residents favored case-based, multidisciplinary discussions. Residents desire more sessions, time for small-group discussions, and legal insight. Satisfaction was high with 90.7% of respondents feeling better prepared to address ethical concerns. Pediatric trainees desire case-based ethics training that incorporates small-group discussions and insight from multidisciplinary topic experts. (shrink)
