Cross-cultural sex differences in mobility and harm avoidance have been widely reported, often emphasizing fitness benefits of long-distance travel for males and high costs for females. Data emerging from adults in small-scale societies, however, are challenging the assumption that female mobility is restricted during reproduction. Such findings warrant further exploration of the ontogeny of mobility. Here, using a combination of machine-learning, mixed-effects linear regression, and GIS mapping, we analyze range size, daily distance traveled, and harm avoidance among Hadza foragers during (...) middle childhood and adolescence. Distance traveled increased with age and, while male adolescents had the longest daily ranges, average daily distance traveled by each sex was similar. We found few age- or sex-related patterns in harm-avoidant responses and a high degree of individual variation. When queried on the same issues, children and their parents were often in alignment as to expectations pertaining to harm avoidance, and siblings tended to behave in similar ways. To the extent that sex differences in mobility did emerge, they were associated with ecological differences in physical threats associated with sex-specific foraging behaviors. Further, we found no strong association between harm avoidance and mobility. Young Hadza foragers of both sexes are highly mobile, regardless of how harm avoidant they are. Taken together, our findings indicate that the causal arrows between harm avoidance and mobility must be evaluated in ecologically specific frameworks where cultural expectations of juvenile mobility can be contextualized.

In this essay collection, leading physicists, philosophers, and historians attempt to fill the empty theoretical ground in the foundations of information and address the related question of the limits to our knowledge of the world. Over recent decades, our practical approach to information and its exploitation has radically outpaced our theoretical understanding - to such a degree that reflection on the foundations may seem futile. But it is exactly fields such as quantum information, which are shifting the boundaries of the (...) physically possible, that make a foundational understanding of information increasingly important. One of the recurring themes of the book is the claim by Eddington and Wheeler that information involves interaction and putting agents or observers centre stage. Thus, physical reality, in their view, is shaped by the questions we choose to put to it and is built up from the information residing at its core. This is the root of Wheeler's famous phrase "it from bit." After reading the stimulating essays collected in this volume, readers will be in a good position to decide whether they agree with this view. (shrink)

In a time when more and more people are discovering they can have a rational morality without an orthodox God, these twenty-four essays reappraise the whole character of Christian ethics and criticize the traditional underpinning of morality by religion. Edited by Ian T. Ramsey, professor of philosophy at Oxford University, the volume is a valuable sequel to the well-known New Essays in Philosophical Theology. The contributors include atheists, agnostics, and Christians. Among them are Ninian Smart, R. B. Braithwaite, Ronald Hepburn, (...) and Iris Murdoch. The essays do not attempt to examine specific Christian questions in any sort of theological detail; rather, their primary concern is with problems that arise principally in a philosophical context. But they are concerned with issues that lie behind the present bewilderment in Christian morality. Stressing the diversity of moral situations, the papers show that these are far from being homogeneous and rule-determined. Moral decision demands personal involvement, activating the possibility of good and bad reasons for making such a decision. The essays point out the character of moral disagreements and also remind us that morality is not only of individual but also of social significance. The last section of the book examines the present concept of natural law; its possible erosion by developments in anthropology, psychology, and philosophy; and whether the possibility exists for a theory of morality that unites both natural-law theory and Christian ethics. Ian T. Ramsey (1915 - 1972) was former Bishop of Durham, County Durham, England, and also served as Nolloth Professor of the Philosophy of the Christian Religion at Oxford University, He was also the author of Religious Language, Models for Divine Activity, and Words About God.

In this paper, I argue that John Milton, in his tragedy Smason Agonistes, raises and offers a solution to a version of the problem of evil raised by Marilyn McCord Adams. Sections I and II are devoted to the presentation of Adams’s version of the problem and its place in the current discussion of the problem of evil. In section III, I present Milton’s version of the problem as it is raised in Samson Agonistes. The solution Milton offers to this (...) problem is taken up in section IV and examined in section V. Last, in section VI, I explore briefly the existential aspect of Milton’s solution. (shrink)

A map of the world that does not include Utopia is not worth even glancing at, for it leaves out the one country at which Humanity is always landing. And when Humanity lands there, it looks out, and, seeing a better country, sets sail. Progress is the realization of Utopias. “The most utopian thing in Utopia is that there are no schools,” writes John Dewey. With these words, Dewey opened his talk to kindergarten teachers on April 21, 1933 at Teachers (...) College, Columbia University. Published a couple days later in the New York Times under the title, “Dewey Outlines Utopian Schools,” we find Dewey in this little-discussed talk fancifully imagining himself among the Utopians—somehow..

The English writers of Dr Coulson’s ‘Common Tradition’ all subscribe to a ‘fiduciary’ as opposed to ‘analytic’ use of language. For Coleridge, unlike Bentham, ‘a language is for action as well as reflection: it must be responded to in all its richness and diversity before we can know what some of its words mean’. A fiduciary language ‘reveals not only the traditions and living principles of a people, but the world of ideas by which all men live’. Coulson argues that (...) the key Coleridgean word ‘idea’ is ‘most clearly understood when it is seen as originating in an understanding of the Church as sacramentally…the presence of Christ in the world’. ‘Such a sacramental conception of the Church is at the heart not only of the Oxford Movement and of Newman’s idea of the Church, but also of that other movement which derives even more directly from Coleridge and is associated with F D Maurice’. But unlike Coleridge and Maurice, for Newman the idea of the Church Catholic must correspond to ‘a tangible, visible, and identifiable empirical entity’, which is not its particular manifestation in the National Church. On the other hand, Coleridge’s ideal of a ‘clerisy’ corresponds to Newman’s insistence on the importance of an educated laity to represent the Church in society; and if Newman could not accept that the idea of the Church is ‘regulated’ by the Nation, nevertheless it is the laity which is the ‘measure’ of his ‘regulating principles’—theology. Where Newman differed so sharply from both Coleridge and Maurice was in his insistence on first asking the Benthamite question, ‘how do we know that Christianity is true?’ before exploring the meaning or relevance of Christian doctrines and institutions. Coulson concludes by claiming that Newman’s final vision of a Church which ‘cannot be conceived sacramentally, and in its idea, in isolation from society’ both supplements Vatican I and anticipates Vatican II, as well as summing up the essential insight of Coleridge and Maurice.

Pax6 is a transcription factor essential for the development of tissues including the eyes, central nervous system and endocrine glands of vertebrates and invertebrates. It regulates the expression of a broad range of molecules, including transcription factors, cell adhesion and short‐range cell–cell signalling molecules, hormones and structural proteins. It has been implicated in a number of key biological processes including cell proliferation, migration, adhesion and signalling both in normal development and in oncogenesis. The mechanisms by which Pax6 regulates its downstream (...) targets likely involve the use of different splice variants and interactions with multiple proteins, allowing it to generate different effects in different cells. Extrapolation to developmental transcription factors in general suggests that variation in the nature of individual factors is likely to contribute to the emergence of differences between tissues.

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)

Last year, we reported a new mechanism of DNA replication in mammals. It occurs inside mitochondria and entails the use of processed transcripts, termed bootlaces, which hybridize with the displaced parental strand as the replication fork advances. Here we discuss possible reasons why such an unusual mechanism of DNA replication might have evolved. The bootlace mechanism can minimize the occurrence and impact of single‐strand breaks that would otherwise threaten genome stability. Furthermore, by providing an implicit mismatch recognition system, it should (...) limit the occurrence of replication‐dependent deletions and insertions, and defend against invading elements. Such a mechanism may also limit attempts to manipulate the mammalian mitochondrial genome. (shrink)

Shapes that are rendered invisible through backward masking are still able to influence motor responses: this is called masked priming. Yet it is unknown whether this influence is on the control of ongoing action, or whether it merely influences the initiation of an already-programmed action. We modified a masked priming procedure such that the critical prime-mask sequence was displayed during the execution of an already-initiated goal-directed pointing movement. Psychophysical tests of prime visibility indicated that the identity of the prime shapes (...) were not accessible to participants for conscious report. Yet detailed kinematic analysis of the finger in motion revealed that masked primes had an influence on the pointing trajectories within 277 ms of their appearance, 56 ms earlier than the trajectory deviations observed in response to the visible masks. These results indicate that subliminal shapes can indeed influence the control of ongoing motor activity. (shrink)

Perceptual learning involves an improvement in perceptual judgment with practice, which is often specific to stimulus or task factors. Perceptual learning has been shown on a range of visual tasks but very little research has explored chromatic perceptual learning. Here, we use two low level perceptual threshold tasks and a supra-threshold target detection task to assess chromatic perceptual learning and category effects. Experiment 1 investigates whether chromatic thresholds reduce as a result of training and at what level of analysis learning (...) effects occur. Experiment 2 explores the effect of category training on chromatic thresholds, whether training of this nature is category specific and whether it can induce categorical responding. Experiment 3 investigates the effect of category training on a higher level, lateralized target detection task, previously found to be sensitive to category effects. The findings indicate that performance on a perceptual threshold task improves following training but improvements do not transfer across retinal location or hue. Therefore, chromatic perceptual learning is category specific and can occur at relatively early stages of visual analysis. Additionally, category training does not induce category effects on a low level perceptual threshold task, as indicated by comparable discrimination thresholds at the newly learned hue boundary and adjacent test points. However, category training does induce category effects on a supra-threshold target detection task. Whilst chromatic perceptual learning is possible, learnt category effects appear to be a product of left hemisphere processing, and may require the input of higher level linguistic coding processes in order to manifest.

Although the recent push toward sustainability is certainly generally a positive development in business and society, we can see many problems in the execution of the theory of sustainability. Where the triple bottom line calls on companies to weigh effects on stakeholders and the environment alongside profit, in practice in many cases, sustainability has been perverted to represent sustainable profits. In these cases, environmental impact and effects on people are only important insofar as they positively contribute to a firm‘s future (...) profits. It is not only practitioners who have often espoused this misappropriated view of sustainability but also academics have lent credibility to this view. In this work, we start by criticizing the often espoused current view of sustainability and remind academics of their responsibility to adapt a more critical view of this narrow focus. We provide examples that show how the current system of capitalism has resulted in outcomes for people and the environment that are patently unacceptable. Reasons are given as to why there is much hesitation to change the status quo. We then call on academics to reexamine what the role of businesses should be within society, what obligations business and corporations should have in society, and how we can encourage meaningful change that results in a better world for future generations.

Over two decades ago, Davids et al. (1994) and Handford et al. (1997) raised theoretical concerns associated with traditional, reductionist, mechanistic perspectives of movement coordination and skill acquisition for sport scientists interested in practical applications for training designs. These seminal papers advocated an emerging consciousness grounded in an ecological approach, signalling the need for sports practitioners to appreciate the constraints-led, deeply entangled and non-linear reciprocity between the organism (performer), task and environment subsystems. Over two decades later, the areas of skill (...) acquisition, practice and training design, performance analysis and preparation, and talent development in sport science have never been so vibrant in terms of theoretical modelling, knowledge generation and innovation, and technological deployment. Viewed at an ecological level of analysis, the work of sports practitioners has progressively transitioned toward the facilitation of an evolving relationship between an organism (athlete, team) and its environment (sports competition). This commentary sets out to explore how these original ideas from Davids et al. (1994) and Handford et al. (1997) have been advanced through the theoretical lens of Ecological Dynamics. Concurrently, we provide case study exemplars, from applied practice in high-performance sports organisations, to illustrate how these contemporary perspectives are shaping the work of sports practitioners (sport ecology designers) in practice and performance preparation.

A study is reported which focused on the problem-solving strategies employed by expert electronics engineers pursuing a real-world task: integrated-circuit design. Verbal protocol data were analysed so as to reveal aspects of the organisation and sequencing of ongoing design activity. These analyses indicated that the designers were implementing a highly systematic solution-development strategy which deviated only a small degree from a normatively optimal top-down and breadth-first method. Although some of the observed deviation could be described as opportunistic in nature, much (...) of it reflected the rapid depth-first exploration of tentative solution ideas. We argue that switches from a predominantly breadth-first mode of problem solving to depth-first or opportunistic modes may be an important aspect of the expert's strategic knowledge about how to conduct the design process effectively when faced with difficulties, uncertainties, and design impasses.

Background. In some organisations, traumatic events via direct or indirect exposure are routine experiences. A NICE review (2005; updated in December 2018) of Post-Traumatic Stress Disorder (PTSD) management in primary and secondary care did not address early interventions for trauma in emergency response organisations. Aims. This scoping review was designed to identify previous research which evaluated the use of early interventions following exposure to primary or secondary trauma, to report on the effectiveness of early interventions models. Method. A scoping review (...) was conducted to examine early interventions for trauma with staff in roles potentially exposed to trauma including: emergency response, military and humanitarian aid. Relevant data was extracted from included studies and outcomes were assessed using meta-ethnography. Results. Fifty studies of mixed quality met the inclusion criteria for this review. Synthesis of study outcomes found that early interventions help emergency responders to manage post-incident trauma when they: are delivered in a manner that respects distinct organisational culture; are supported by organisations and senior management, and; harness existing social cohesion and peer support systems within teams. Conclusions. This review demonstrates that early interventions support emergency responders following exposure to trauma when: tailored to the needs of the population, are supported by the host organisation, and harness existing social cohesion and peer support processes within a team or unit. We identify a number of recommendations for the delivery and evaluation of early interventions for psychological trauma in emergency response organisations. (shrink)
