As the HIV epidemic continues to grow worldwide, women are increasingly and disproportionally affected. With the introduction of anti-retroviral medications that have been found to effectively prevent perinatal transmission of HIV, the approach to HIV testing in pregnant women has grown increasingly more controversial. In recent years, the model of voluntary counseling and testing (VCT) has come into question with opt-out testing now advocated for by the Centers for Disease Control and occurring widely in pregnancy. The benefits of opt-out testing (...) are numerous and may justify its use in replacing the VCT that many have come to see as insufficient. An ethical analysis of opt-out testing suggests it may be at odds with true informed consent and involve a degree of coercion that would not be allowed outside the prenatal setting. If opt-out testing is going to remain the standard of care then the ethical issues it raises must be made transparent. Strategies need to be designed for ensuring that HIV counseling and testing in pregnancy is done in accordance with ethical and reproductive rights principles. (shrink)

Population-based research is enhanced by biological measures, but biological sampling raises complex ethical issues. The third British National Survey of Sexual Attitudes and Lifestyles (Natsal-3) will estimate the population prevalence of five sexually transmitted infections (STIs) (Chlamydia trachomatis, Neisseria gonorrhoeae, human papillomavirus (HPV), HIV and Mycoplasma genitalium) in a probability sample aged 16–44 years. The present work describes the development of an ethical approach to urine testing for STIs, including the process of reaching consensus on whether to return results. The (...) following issues were considered: (1) testing for some STIs that are treatable and for which appropriate settings to obtain free testing and advice are widely available (Natsal-3 provides all respondents with STI and healthcare access information), (2) limits on test accuracy and timeliness imposed by survey conditions and sample type, (3) testing for some STIs with unknown clinical and public health implications, (4) how a uniform approach is easier to explain and understand, (5) practical difficulties in returning results and cost efficiency, such as enabling wider STI testing by not returning results. The agreed approach, to perform voluntary anonymous testing with specific consent for five STIs without returning results, was approved by stakeholders and a research ethics committee. Overall, this was acceptable to respondents in developmental piloting; 61% (68 of 111) of respondents agreed to provide a sample. The experiences reported here may inform the ethical decision making of researchers, research ethics committees and funders considering population-based biological sampling. (shrink)

How long does a quantum particle take to traverse a classically forbidden energy barrier? In other words, what is the correct expression for quantum tunnelling time? This seemingly simple question has inspired widespread debate in the physics literature. I argue that we should not expect the orthodox interpretation of quantum mechanics to provide a unique correct expression for quantum tunnelling time, because to do so it would have to provide a unique correct answer to a question whose assumptions are in (...) tension with its core interpretational commitments. I explain how this conclusion connects to time’s special status in quantum mechanics, the meaningfulness of classically inspired concepts in different interpretations of quantum mechanics, the prospect of constructing experimental tests to distinguish between different interpretations, and the status of weak measurement in resolving questions about the histories of subensembles.

Scholarship in education beyond school has developed largely outside university departments of education, and has rarely engaged systematically with the study of education in schools. The paper concentrates on three areas: adult education, higher education, and further education. The development of the extra-mural tradition meant that adult education was less an object of scholarly study than a means of spreading scholarship to the wider population, with important exceptions such as historical studies. Since the 1970s, the volume of research and postgraduate (...) education in adult education in British universities has grown considerably. The study of higher education was marginal until the 1960s; its subsequent development was relatively slow until the 1990s, when the quality of university teaching came under wider external scrutiny. The study of further education and vocational training is characterised by disciplinary fragmentation, with much activity taking place in departments of psychology, economics, sociology and management, as well as in those former polytechnics that specialised in training further education teachers. The rise of integrative concepts such as lifelong learning suggest greater potential for cross-disciplinary scholarship that can engage the diverse body of those interested in teaching and research about this field.

Questions surrounding the evolution of cooperation, especially human cooperation, have driven research in many disciplines. Two key methodologies used to research and explain the evolution of cooperation are modeling and narrative construction. A number of scientists and philosophers have suggested that advancing research on the evolution of cooperation will require integrating models and narratives. But, relatively little has been said about what challenges exist to integrating models and narratives, how to go about integrating models and narratives, and what particular benefits (...) might be gained by accomplishing such integration. In this dissertation project, I address these questions in order to show how models and narratives can be integrated to produce better research on and explanations of the evolution of cooperation. The major challenge to integrating models and narratives concerning the evolution of cooperation that I address in this dissertation stems from the criticisms that such models and narratives lack empirical support. I answer this challenge by defending models and narratives from these criticisms. In the case of models, I argue both that at least some models of the evolution of cooperation have stronger empirical support than supposed by critics and that evolutionary robotics modeling approaches can be used to create even better models. In the case of narratives, I argue that several means of defending narratives from evidential challenges already developed by philosophers can be used to defend narratives about the evolution of cooperation as well. To show how narratives and models can be integrated to better research and explain the evolution of cooperation, I first establish an account of integration by drawing on the work of other philosophers. I then argue that models and narratives can provide certain benefits to each other via integration. Models can benefit from integration with narratives by using the narratives as sources of information as well as hypotheses to test. Indeed, as models are used to test such hypotheses, they also gain explanatory power. Narratives can benefit from integration with models by using the models as sources of support and constraint. Moreover, models can help deepen the understanding of historical contingency provided by narratives. (shrink)

This exploratory paper considers the concept of generation in the context of learning across the life course. Although researchers have often found considerable inequalities in participation by age, as well as strongly articulated attitudinal differences, there have so far been only a handful of studies that have explored these patterns through the perspective of generational formations. The paper is primarily conceptual, exploratory and reflective, setting out a number of approaches to the concept of generations, most of which derive largely from (...) debates with the ghost of Karl Mannheim; it then considers how these concepts of generation have been applied to understandings of educational inequalities in recent research in Germany and the Nordic nations. It then examines the dynamics of inter-generational relations in learning, drawing on research undertaken as part of the Teaching and Learning Research Programme. The paper argues that although inter-generational dynamics are a relatively neglected dimension of Anglophone research on life chances and learning, there is a strong case for understanding their dual roles in both inequality and cohesion. It concludes by outlining some themes and areas for further investigation in the future. (shrink)

This paper attempts a comprehensive account of the comparative merits of paracomplete and dialetheic approaches to the semantic paradoxes. It argues that aside from issues about conditionals, there can be no strong case for paracomplete approaches over dialetheic, or dialetheic over paracomplete, and indeed that in absence of conditionals, the two approaches are plausibly seen as notational variants. Graham Priest disagrees: many of his arguments favoring dialetheic solutions over paracomplete do not turn on issues about conditionals. The paper discusses his (...) arguments on these points in some detail. On the matter of conditionals, it argues that extant paracomplete approaches are far better than extant dialetheic approaches, a fact that traces in part to dialetheists having focused too heavily on “relevant logics”. It holds out hope for better dialetheic treatments of conditionals, but it also suggests that this is the one area where paracomplete approaches are inevitably better. (shrink)

Throughout the biological and biomedical sciences there is a growing need for, prescriptive ‘minimum information’ (MI) checklists specifying the key information to include when reporting experimental results are beginning to find favor with experimentalists, analysts, publishers and funders alike. Such checklists aim to ensure that methods, data, analyses and results are described to a level sufficient to support the unambiguous interpretation, sophisticated search, reanalysis and experimental corroboration and reuse of data sets, facilitating the extraction of maximum value from data sets (...) them. However, such ‘minimum information’ MI checklists are usually developed independently by groups working within representatives of particular biologically- or technologically-delineated domains. Consequently, an overview of the full range of checklists can be difficult to establish without intensive searching, and even tracking thetheir individual evolution of single checklists may be a non-trivial exercise. Checklists are also inevitably partially redundant when measured one against another, and where they overlap is far from straightforward. Furthermore, conflicts in scope and arbitrary decisions on wording and sub-structuring make integration difficult. This presents inhibit their use in combination. Overall, these issues present significant difficulties for the users of checklists, especially those in areas such as systems biology, who routinely combine information from multiple biological domains and technology platforms. To address all of the above, we present MIBBI (Minimum Information for Biological and Biomedical Investigations); a web-based communal resource for such checklists, designed to act as a ‘one-stop shop’ for those exploring the range of extant checklist projects, and to foster collaborative, integrative development and ultimately promote gradual integration of checklists.

Motor training to improve walking and balance function is a common aspect of rehabilitation following motor-incomplete spinal cord injury. Evidence suggests that moderate- to high-intensity exercise facilitates neuroplastic mechanisms that support motor skill acquisition and learning. Furthermore, enhancing corticospinal drive via transcranial direct current stimulation may augment the effects of motor training. In this pilot study, we investigated whether a brief moderate-intensity locomotor-related motor skill training circuit, with and without tDCS, improved walking and balance outcomes in persons with MISCI. In (...) addition, we examined potential differences between within-day and between-day effects of MST. Twenty-six adults with chronic MISCI, who had some walking ability, were enrolled in a 5-day double-blind, randomized study with a 3-day intervention period. Participants were assigned to an intensive locomotor MST circuit and concurrent application of either sham tDCS or active tDCS. The primary outcome was overground walking speed measured during the 10-meter walk test. Secondary outcomes included spatiotemporal gait characteristics, peak trailing limb angle, intralimb coordination, the Berg Balance Scale, and the Falls Efficacy Scale-International questionnaire. Analyses revealed a significant effect of the MST circuit, with improvements in walking speed, cadence, bilateral stride length, stronger limb TLA, weaker limb ACC, BBS, and FES-I observed in both the MST+tDCSsham and MST+tDCS groups. No differences in outcomes were observed between groups. Between-day change accounted for a greater percentage of the overall change in walking outcomes. In persons with MISCI, brief intensive MST involving a circuit of ballistic, cyclic locomotor-related skill activities improved walking outcomes, and selected strength and balance outcomes; however, concurrent application of tDCS did not further enhance the effects of MST.Clinical Trial Registration[ClinicalTrials.gov], identifier [NCT03237234].

_Experience and Value: Essays on John Dewey and Pragmatic Naturalism _brings together twelve philosophical essays spanning the career of noted Dewey scholar, S. Morris Eames. The volume includes both critiques and interpretations of important issues in John Dewey’s value theory as well as the application of Eames’s pragmatic naturalism in addressing contemporary problems in social theory, education, and religion. The collection begins with a discussion of the underlying principles of Dewey’s pragmatic naturalism, including the concepts of nature, experience, and philosophic (...) method. Essays “Experience and Philosophical Method in John Dewey” and “Primary Experience in the Philosophy of John Dewey” develop what Eames believed to be a central theme in Dewey’s thought and provide a theoretical framework for subsequent discussion. The volume continues with specific applications of this framework in the areas of value theory, moral theory, social philosophy, and the philosophy of religion. Eames’s analysis of value exposes the connection between the immediately felt values of experience and the more sophisticated judgments of value that are the product of reflection. From this basis in moral theory, Eames considers the derivation of judgments of obligation from judgments of fact. This discussion provides a grounding for a consideration of contemporary social issues directed by naturalistic and scientific principles. In the third section, with regard to educational theory, Eames considers possible resolutions of the current dichotomy between the factual worldview of science and the humanistic worldview of the liberal arts. The comprehensive article, “Dewey’s Views of Truth, Beauty, and Goodness,” connects the essays of the first and second sections and explores the placement of Dewey’s value theory with respect to morals and aesthetics. With “Creativity and Democracy,” in the fourth section, Eames also considers the concept of democracy from the standpoint of current and historical issues faced by society. This article hints at a major project of Eames’s intellectual life—the theory of democracy. The volume concludes with a discussion of the difficulty of maintaining the values of religious experience in a scientifically and technologically sophisticated world, the very topic that first brought Eames to philosophy—the meaning of religion and the religious life. Suggested solutions are offered in “The Lost Individual and Religious Unity.” _Experience and Value: Essays on John Dewey and Pragmatic Naturalism _illuminates Eames’ life of inquiry, a life that included moral, social, aesthetic, and religious dimensions of value—all suffused with the influence of John Dewey. _ _ __.

To better understand ethical issues involved in the field of human genetics and promote debate within the scientific community, the author surveyed scientists who engage in human genetics research about the pros, cons, and ethical implications of genetic testing. This study contributes systematic data on attitudes of scientific experts. The survey finds respondents are highly supportive of voluntary testing and the right to know one's genetic heritage. The majority consider in utero testing and consequent pregnancy termination acceptable for cases (...) involving likelihood of serious disease but disapprove for genetic reasons they consider arbitrary, leaving a gray area of distinguishing between treatment of disorders and enhancement still to be resolved. While safeguarding patient confidentiality versus protecting at-risk third parties presents a dilemma, preserving privacy from misuse by institutional third parties garners strong consensus for legislation against discrimination. Finally, a call is made for greater genetic literacy. (shrink)

Through qualitative surveys, a team of law students, law professors, physicians, and residents explored the perceptions of neurology residents towards referral to appropriate legal resources in an academic training program. Respondents reported feeling uncomfortable screening their patients for health-harming legal needs, which many attributed to a lack of training in this area. These findings indicate that neurology residents would benefit from training on screening for social factors that may be impacting their patients’ health.

Field dependence-independence (FDI) is a widely studied dimension of cognitive styles designed to measure an individual’s ability to identify embedded parts of an organized visual field as entities separate from that given field. The research aims to determine whether the brain activity features that are considered to be perceptual switching indicators could serve as robust features, differentiating Field-Dependent (FD) from Field-Independent (FI) participants. Previous research suggests that various features derived from event related potentials (ERP) and (...) frequency features are associated with the perceptual reversal occurring during the observation of a bistable image. In this study, we combined these features in the context of a different experimental scheme using ambiguous and unambiguous stimuli during participants’ perceptual observations. We assessed the participants’ FD-I classification with the use of the Hidden Figures Test (HFT). Results show that the peak amplitude of the frontoparietal positivity, the late positive deflection in frontal and parietal areas, is higher for the FD group at specific locations of the left lobe, whereas it occurs later for the FD group at the central and occipital electrodes. Additionally, the FD group exhibits higher levels of gamma power before stimulus onset at channel TP10 and higher gamma power during reversal at the right centroparietal electrodes (T8, CP6 and TP10). The peak amplitude of the reversal positivity, the positive deflection during the reversal, is higher for the FD group at the rear right lobe (P4). (shrink)

Lower extremity non-contact soft tissue injuries are prevalent in elite futsal. The purpose of this study was to develop robust screening models based on pre-season measures obtained from questionnaires and field-based tests to prospectively predict LE-ST injuries after having applied a range of supervised Machine Learning techniques. One hundred and thirty-nine elite futsal players underwent a pre-season screening evaluation that included individual characteristics; measures related to sleep quality, athlete burnout, psychological characteristics related to sport performance and self-reported perception of (...) chronic ankle instability. A number of neuromuscular performance measures obtained through three field-based tests [isometric hip strength, dynamic postural control and lower extremity joints range of motion ] were also recorded. Injury incidence was monitored over one competitive season. There were 25 LE-ST injuries. Only those groups of measures from two of the field-based tests, as independent data sets, were able to build robust models [area under the receiver operating characteristic curve score ≥0.7] to identify elite futsal players at risk of sustaining a LE-ST injury. Unlike the measures obtained from the five questionnaires selected, the neuromuscular performance measures did build robust prediction models. The inclusion in the same data set of the measures recorded from all the questionnaires and field-based tests did not result in models with significantly higher performance scores. The model generated by the UnderBagging technique with a cost-sensitive SMO as the base classifier and using only four ROM measures reported the best prediction performance scores. The models developed might help coaches, physical trainers and medical practitioners in the decision-making process for injury prevention in futsal. (shrink)

Anecdotal evidence has long lamented the status of social studies in elementary classrooms as observed by preservice teachers. As standardized testing has risen for mathematics and language arts, social studies has been pushed aside. In the aftermath of accountability legislation such as No Child Left Behind, research indicates that social studies is less visible in elementary classrooms due to an instructional focus on tested content areas (e.g. math, language arts, reading). In this study, approximately 90 elementary preservice teachers enrolled in (...) a social studies methods course responded to a survey and indicated the frequency and quality of lessons they observed over the course of a single semester. Findings report that preservice elementary teachers witnessed few, if any, lessons in social studies in the elementary classroom. Implications for teacher education are discussed. (shrink)

Experiments are described, using electroencephalography (EEG) and simple tests of performance, which support the hypothesis that collapse of a quantum field is of importance to the functioning of the brain. The theoretical basis of our experiments is derived from Penrose (1989) who suggested that conscious decision-making is a manifestation of the outcome of quantum computation in the brain involving collapse of some relevant wave function. He also proposed that collapse of any wave function depends on a gravitational criterion. As (...) different brain areas are known to subserve different functions, we argue that `Penrose collapse' must occur in a particular brain area when performing a task that uses it. Further, taking an EEG from the area should amplify the gravitational prerequisite for collapse, so affecting task performance. There are no non-quantum theories which could lead one to expect that taking an EEG could directly affect task performance by subjects. The results of both pilot and main experiments indicated that task performance was indeed influenced by taking an EEG from relevant brain areas. Control experiments suggested that the influence was quantum mechanical in origin, and was not due to any experimental artefact. The results are statistically significant and merit attempts at replication in an independent laboratory, preferably with more sophisticated equipment than was available to us. (shrink)

Testing of candidate biological control agents to estimate their likely field host ranges in the area of release has been part of weed biological control for several decades, with evolving techniques and goals. Similar efforts have been made less often for parasitoids and predators being introduced for arthropod biological control. Here, we review both techniques of host range testing and social objectives of such screening. We ask whether agents introduced for arthropod biological control should be subjected to host (...) range testing before release, and if so, are methods used for estimating host ranges of herbivorous arthropods appropriate, or are different approaches needed. Current examples in which host range testing has been employed for arthropod biological control are reviewed. We conclude with recommendations concerning guiding principles about use of host range testing. We recommend modest expansion of host range testing for arthropod biological control for projects on continents. We recommend more extensive testing for projects of introduction onto islands. We note that introductions to islands could provide opportunities to gain experience in use of host range estimation for this class of organisms and to conduct post release evaluations of host ranges. We urge caution in efforts to mandate host range testing but simultaneously recommend consultation between biological control workers and insect conservationists. (shrink)

The increasing digitalization in the field of psychological and educational testing opens up new opportunities to innovate assessments in many respects (e.g., new item formats, flexible test assembly, efficient data handling). In particular, computerized adaptive testing provides the opportunity to make tests more individualized and more efficient. The newly developed continuous calibration strategy (CCS) from Fink, Born, Spoden, and Frey (2018) makes it possible to construct computerized adaptive tests in application areas where separate calibration studies are not feasible. (...) Due to the goal of reporting on a common metric across test cycles, the equating is crucial for the CCS. The quality of the equating depends on the common items selected and the scale transformation method applied. Given the novelty of the CCS, the aim of the study was to evaluate different equating setups in the CCS and to derive practical recommendations. The impact of different equating setups on the precision of item parameter estimates and on the quality of the equating was examined in a Monte Carlo simulation, based on a fully crossed design with the factors common item difficulty distribution (bimodal, normal, uniform), scale transformation method (mean/mean, mean/sigma, Haebara, Stocking-Lord), and sample size per test cycle (50, 100, 300). The quality of the equating was operationalized by three criteria (proportion of feasible equatings, proportion of drifted items, and error of transformation constants). The precision of the item parameter estimates increased with increasing sample size per test cycle, but no substantial difference was found with respect to the common item difficulty distribution and the scale transformation method. With regard to the feasibility of the equatings, no differences were found for the different scale transformation methods. However, when using the moment methods (mean/mean, mean/sigma), quite extrem levels of error for the transformation constants A and B occurred. Among the characteristic curve method the performance of the Stocking-Lord method was slightly better than for the Haebara method. Thus, while no clear recommendation can be made with regard to the common item difficulty distribution, the characteristic curve methods turned out to be the most favorable scale transformation methods within the CCS.

Large amount of data are exchanged and the internet is turning into twenty-first century Silk Road for data. Machine learning (ML) is the new area for the applications. The artificial intelligence (AI) is the field providing machines with intelligence. In the last decades, more developments have been made in the field of ML and deep learning. The technology and other advanced algorithms are implemented into more computational constrained devices. The online English test system based on ML (...) breaks the shackles of the traditional paper English test and improves the efficiency of the English test. At the same time, it also maintains the fairness of English test and improves the marking speed. In order to realize an online English test system based on ML and facilitate the assessment of students’ college English courses, this paper mainly adopts relevant research and design on the main functional modules, key technologies, and functional realization of the online English test. The brand-new powerful teaching software and the online examination system can help schools to conduct more systematic and scientific management. The conclusion shows that as brand-new and powerful teaching software, the online examination system can help schools to conduct more systematic and scientific management. (shrink)

Bank Street College of Education professor Salvatore Vascellaro is a leading advocate of taking children and teachers into a wider world as the key to improving our struggling schools. Combining practical and theoretical guidance, Out of the Classroom and into the World visits a rich variety of classrooms transformed by innovative field trip curricula--showing how students’ hearts and minds are opened as they discover how a suspension bridge works, what connects them to the people and places of their neighborhood, (...) and as they come to understand the ecosystem of a river by following it to its source. Vascellaro shows, equally, that what teachers can offer children is fueled by their own engagement with the world, and he offers stunning examples of teachers awakened by their direct experiences with the social issues plaguing American society--from the flood-torn areas of New Orleans to the mining areas of West Virginia. Based on the core principles of progressive pedagogy, and the wisdom gained from Vascellaro’s experience as a teacher, school administrator, and teacher educator, Out of the Classroom and into the World is a direct retort to test scores and standards as adequate measures of teaching and learning--an inspiring call and major new resource for anyone interested in reinvigorating America’s classrooms.

The study of imitation and other mechanisms of social learning is an exciting area of research for all those interested in understanding the origin and the nature of animal learning in asocial context. Moreover, imitation is an increasingly important research topic in Artificial Intelligence and social robotics which opens up the possibility ofindividualized social intelligencein robots that are part of a community, and allows us to harness not only individual learning by the single robot, but also the acquisition of (...) new skills by observing other members of the community. After an introduction to the main research issues in research on imitation in various fields, we motivate the particular focus of this work, namely thecorrespondence problem. We describeAction Learning for Imitation via Correspondences between Embodiments, an implemented generic framework for solving the correspondence problem between differently embodied robots. Alice enables a robotic agent to learn a behavioral repertoire suitable to performing a task by observing a model agent. Importantly, the model agent could possibly possess a different type of body, e.g. a different number of limbs or joints, a different height, different sensors, a different basic action repertoire, etc. Previously, in a test-bed where the agents differed according to their possible movement patterns, we demonstrated that the character of imitation achieved will depend on the granularity of subgoal matching, and on the metrics used to evaluate success.In our current work, we implemented Alice in a new test-bed calledRabitwhere simple simulated robotic arm agents use various metrics for evaluating success according to actions, states, effects, or weighted combinations.We examine the roles ofsynchronization,looseness of perceptual matching, and ofproprioceptive matchingby a series of experiments. Also, we study how Alice copes withchanges in the embodimentof the imitator during learning. Our simulation results suggest thatsynchronizationandloose perceptual matchingallow for faster acquisition of behavioral compentencies at low error rates.Social learning plays a role as areplicationmechanism for behaviors and results invariabilitywhen the transmitted behavior differs from the model’s behavior, thus providing theevolutionary substrate for cultureand its pre-cursors. Social learning in robotics could therefore serve as the basis for culture in societies whose members include artificial agents. We address the use of imitative social learning mechanisms like Alice for transmission of skills between robots, and give first examples of transmission of a skill despite differences in embodiment of agents involved. In the particular setup, transmission occurs through a chain, as well as emerging in cyclic arrangements of robots. These simple examples demonstrate that by using social learning and imitation,cultural transmissionis possible among robots, even in heterogeneous groups of robots. (shrink)

Restoration involves individuals’ physical, psychological and social resources, diminished by meeting demands of everyday life. Psychological restoration can be provided by specific environments, in particular by natural environments. Research reports a restorative effect of nature on human beings, specifically in terms of the psychological recovery from attention fatigue and restored mental resources previously spent in activities that require attention. Two field studies in two Italian primary schools tested the hypothesized positive effect of recess-time spent in a natural (vs. built) (...) environment on pupils’ cognitive performance and their perceived restorativeness, using standardized tests. In Study 1, children’s psychological restoration was assessed measuring sustained and selective attention, working memory, and impulse’ control, before and after morning recess-time. Team standardized play-time was conducted in a natural (vs. built) environment, measuring perceived restorativeness after each recess-time. Results showed a greater increase in sustained and selective attention, concentration, and perceived restorativeness from pre-test to post-test after the Natural Environment condition. In Study 2 the positive effect of free-play recess-time in a natural (vs. built) environment was assessed during the afternoon school-time on sustained and selective attention and perceived restorativeness. Results showed an increase of sustained and selective attention after the Natural Environment condition (vs. Built) and a decrease after the built environment break. Higher scores in perceived restorativeness were registered after the Natural (vs. Built) Environment condition. Team standardized and individual free-play recess in a natural environment (vs. built) support pupils’ attention restoration during both morning and afternoon school-time, as well as their perceived restorativeness of recess environment. Theoretical and practical implications are discussed in terms of nature’s role both for school ground design or re-design, and for school’s activities organization. (shrink)

The aim of this study was to assess the predictive capacity of some of the most relevant cognitive skills pertaining to the academic field as measured by the Spanish Primary School Aptitude Test Battery. This psychometric tool was applied to all students who were enrolled in the final year of Early Childhood Education in the public schools of the province of Alicante and a follow-up of their academic progress was carried out when they completed Primary Education. The results (...) obtained show that medium-high and high scores in Verbal Aptitude and Numerical Aptitude tests in Early Childhood Education, can predict academic success at the end of Primary Education in instrumental subjects such as: Language and Mathematics. We have determined the importance of developing pedagogical programs that stimulate the development of these skills during Early Childhood Education, while implementing support strategies during Primary Education, for those students who present underdeveloped aptitudes in these areas. In this way, school difficulties would be prevented in the instrumental subjects that provide access to other academic areas. (shrink)

During the last several years social scientists have increasingly recognized the impact of globalization on research and practice. It is imperative that psychology as a field be cognizant of this ongoing shift and that psychologists begin to integrate their various models, theories, and perspectives into a global curriculum.Sponsored by the International Testing Commission, The ITC International Handbook of Testing and Assessment is dedicated to the advancement of theory, research, and practice in the area of international testing and assessment (...) in psychology, education, counseling, organizational behavior, human resource management, and related disciplines. Bringing together international contributors from a range of disciplines, each chapter provides a review of testing and assessment research and practices around the world as well as a discussion of conceptual and methodological challenges to help advance the field. As The ITC International Handbook of Testing and Assessment, it also provides a historical perspective of international testing, the development of the ITC, and its guidelines. Recognizing that cultural and international contexts are essential to a true and accurate psychology, the authors describe how cultural, economic, political, and social factors in different countries frame the science and practice of testing and assessment. The ITC International Handbook of Testing and Assessment is a must-have resource for testing professionals and graduate students from psychology and related disciplines. (shrink)

Categorical predictions have been proposed as the key mechanism supporting the fast pace of syntactic composition in language. Accordingly, grammar-based expectations are formed—e.g., the determiner “a” triggers the prediction for a noun—and facilitate the analysis of incoming syntactic information, which is then checked against a single or few other word categories. Previous functional neuroimaging studies point towards Broca’s area in the left inferior frontal gyrus as one fundamental cortical region involved in categorical prediction during incremental language processing. Causal evidence (...) for this hypothesis is however still missing. In this study, we combined Electroencephalography and Transcranial Magnetic Stimulation to test whether Broca’s area is functionally relevant in predictive mechanisms for language. We transiently perturbed Broca’s area during the first word in a two-word construction, while simultaneously measuring the Event-Related Potential correlates of syntactic composition. We reasoned that if Broca’s area is involved in predictive mechanisms for syntax, disruptive TMS during the first word would mitigate the difference in the ERP responses for predicted and unpredicted categories in basic two-word constructions. Contrary to this hypothesis, perturbation of Broca’s area at the predictive stage did not affect the ERP correlates of basic composition. The correlation strength between the electrical field induced by TMS and the ERP responses further confirmed this pattern. We discuss the present results considering an alternative account of the role of Broca’s area in syntactic composition, namely the bottom-up integration of words into constituents, and of compensatory mechanisms within the language predictive network.

High throughput time-resolved observations of accreting collapsed objects at X-ray energies provide key information on the motions of matter orbiting a few gravitational radii away from black holes. Predictions of general relativity in the strong field regime, such as relativistic epicyclic motions, precession, light bending and the presence and radius of an innermost stable circular orbit in the close vicinity of a black hole can be verified by making use of two powerful diagnostics, namely relativistically broadened \ lines and (...) variability on dynamical timescales, quasi periodic oscillations in particular. Moreover tomography and reverberation techniques relying upon combined spectral timing and polarimetric timing provide an entirely new perspective in the field. Both the low and high spacetime curvature regimes of gravity can be probed by studying black holes of vastly different masses in X-ray binaries and Active Galactic Nuclei, opening up the possibility of testing also some alternative theories of gravity. To achieve these goals, very large area X-ray instrumentation with good spectral resolution and polarimetric capability is required. Prospects and projects in this area of research are briefly surveyed. (shrink)

Following Kenya’s independence in 1963, scientists converged on an ecologically sensitive area in southern Kenya on the northern slope of Mt. Kilimanjaro called Amboseli. This region is the homeland of the Ilkisongo Maasai who grazed this ecosystem along with the wildlife of interest to the scientists. Biologists saw opportunities to study this complex community, an environment rich in biological diversity. The Amboseli landscape proved to be fertile ground for testing new methods and lines of inquiry in the biological sciences (...) that were generalizable and important for shaping natural resource management policies in Kenya. However, the local community was in the midst of its own transformation from a primarily transhumant lifestyle to a largely sedentary one, a complex political situation between local and national authorities, and the introduction of a newly educated generation. This article examines the intersection of African history and field science through the post-colonial Africanization of Kenyan politics, the broadening of scientific practices in Amboseli in previously Western-occupied spaces to include Kenyan participants, and an increasing awareness of the role of local African contexts in the results, methods, and implications of biological research. “Africanization” as an idea in the history of science is multifaceted encompassing not just Africans in the scientific process, but it needs an examination of the larger political and social context on both a local and national level.

Honor systems are a cheap and simple way for marketing low-price goods. These sale systems are dependent on the honesty of customers and can only tolerate a certain share of free-riders. In an experimental field study, we investigate a case where honesty has almost disappeared, namely an honor system for the sale of newspapers on weekends. In the chosen urban study area, only a minority of customers comply with payment norms. In this difficult setting, we tested the use (...) of eye images and descriptive social norms as cues to improving payment morale over a period of 24 weeks. We find that interventions based on eye cues as well as normative appeals do not evoke a transition from low to high levels of honesty. However, our results suggest that such interventions might still have the potential to marginally increase mean payments and therefore be economically profitable for operators of large-scale honor systems.

The study of the post-Communist towns of East Europe and Russia does not only present the social sciences with the opening of a new field and the attraction of exoticism close at hand. They are a remarkable observatory of the complex relations which unite the material facets of urban life (extension of the built-up area, architectural forms, types of distribution of infrastructures and services) and the social structures (mode of government, nature of the economic initiative, expressions of sociability). (...) In three-quarters of a century for Russia, in fifty years for the countries of East Europe, cities many ages old were to have two changes of system: from liberal industrial capitalism to the controlled Communist economy, from interventionist autarchy to the globalized market. To give the lie to the poet (Baudelaire), towns change no faster than the hearts of mortals but beat to the rhythm of their continuities, their aspirations and their dreams. (shrink)

Organic farming is expected to contribute to conserving national biodiversity on farms, especially remnant, old, and undisturbed small biotopes, forests, and permanent grassland. This objective cannot rely on the legislation of organic farming solely, and to succeed, farmers need to understand the goals behind it. A set of indicators with the purpose of facilitating dialogues between expert and farmer on wildlife quality has been developed and tested on eight organic farms. “Weed cover in cereal fields,” was used as an indicator (...) of floral and faunal biodiversity in the cultivated land, and “uncultivated biotope area” on the farm was used as a general measure of wildlife habitats. Functional grouping of herbaceous plants (discriminating between “high conservation value” plant species and “competitive”/“ruderal” species) and low mobility butterflies were used as indicators of conservation value, especially focusing on the few sites left with considerable remnant conservation value. The dialog processes revealed that the organic farmers’ ideas and goals of conservation of wildlife quality were not necessarily the same as for biologists; the farmers expressed very different opinions on the biological rooted idea, that wildlife quality is related to the absence of agricultural impact. However, farmers also stated that the information given by the indicators and especially the dialogue with the biologist had influenced their perception and awareness of wildlife. We conclude that, combined with a dialogue process, using these indicators when mapping wildlife quality could be an important key component of a farm wildlife management advisory tool at farm level.

In a development of the ecosemiotic vivo-scape concept, a ‘safety eco-field’ is proposed as a model of a species response to the safety of its environment. The safety eco-field is based on the ecosemiotic approach which considers environmental safety as a resource sought and chosen by individuals to counter predatory pressure. To test the relative safety of different locations within a landscape, 66 bird feeders (BF) were deployed in a regular 15 × 15 m grid in a (...) rural area, surrounded by shrubs, small trees, hedgerows, and buildings. On each of 48 days in November 2021 and February and March 2022, dried mealworms were placed on each BF and counts of larvae at each BF were made at noon and dusk. The European robin (Erithacus rubecula) and the great tit (Parus major) were the most regular visitors to the BFs. Land cover at each BF was recorded. Bird behaviour at the BFs was noted from direct video recordings of the birds at nine selected BFs, totalling 32 daily sessions in March. The different behaviours of the European robin and the great tit were observable. The safety eco-field changed according to the month and the time of day. The distance of the BF from the woodland edges seemed to be important only in the morning. In the afternoon, BFs that were more distant from the woodland edges received the highest number of visits. Weather conditions were found to influence the number of mealworms removed, but this requires further investigation. A significant relationship between land cover and the number of mealworm larvae removed from the BFs was observed. Within the grid of BF, three regions were distinguishable which were related to land cover in the safety eco-field process. The experimental framework confirms the adequacy, at least for birds that have cryptic predators, to map the landscape as a proxy of safety resource. From the video recordings it was noted that the European robin visits were distributed throughout the day without apparent temporal preferences, while the great tit visits were concentrated in the central part of the day. This result has the limitation of the short period of observation (March) and should be extended to the entire period of the experiment to eventually capture seasonal variation. The experimental evidence obtained confirms that the ecosemiotic-based models of safety eco-field are an efficient approach to explain bird feeding preferences and behaviours. (shrink)

Toward A Sociological Imagination builds on the ideas C. Wright Mills expressed in The Sociological Imagination for an approach to the scientific method broad enough to open up to the full range of knowledge within the sociology discipline. In this book, nine sociologists and one philosopher provide detailed tests of the utility of the approach within diverse substantive sociological areas.

Whistleblowers have significantly shaped the state of contemporary society; in this context, this research sheds light on a persistently neglected research area: what are the key determinants of whistleblowing within government agencies? Taking a unique methodological approach, we combine evidence from two pieces of fieldwork, conducted using both primary and secondary data from the US and Indonesia. In Study 1, we use a large-scale survey conducted by the US Merit Systems Protection Board (MSPB). Additional tests are conducted in Study (...) 1, making comparisons between those who have and those who do not have whistleblowing experience. In Study 2, we replicate the survey conducted by the MSPB, using empirical data collected in Indonesia. We find a mixture of corroboration of previous results and unexpected findings between the two samples (US and Indonesia). The most relevant result is that perceived organizational protection has a significant positive effect on whistleblowing intention in the US sample, but a similar result was not found in the Indonesian sample. We argue that this difference is potentially due to the weakness of whistleblowing protection in Indonesia, which opens avenues for further understanding the role of societal cultures in protecting whistleblowers around the globe.
