Quantitative studies of science and technology represent the research field of utilization of mathematical, statistical, and data-analytical methods and techniques for gathering, handling, interpreting, and predicting a variety of features of the science and technology enterprise, such as performance, development, and dynamics. The field has both strongly developed applied research as well as basic research characteristics. The principal purpose of this handbook is to present this wide range of topics in sufficient depth to give readers a reasonably systematic understanding of (...) the domain of contemporary quantitative studies of science and technology, a domain which incorporates theory, methods and techniques, and applications. In addressing this domain, the handbook aims at different groups of readers: those conducting research in the field of science and technology, including (graduate) students, and those who are to use results of the work presented in this book.

This book analyzes the sociopolitical sensibilities of Black aesthetics in society by examining the historical and political context in which Black aesthetics emerged; analyzing various Black aesthetic perspectives that speak to social justice; exploring the interpretive conditions necessary to perceive Black aesthetics as a language of social justice.

Prior knowledge structures (or schemas) confer multiple behavioral benefits. First, when we encounter information that fits with prior knowledge structures, this information is generally better learned and remembered. Second, prior knowledge can support prospective planning. In humans, memory enhancements related to prior knowledge have been suggested to be supported, in part, by computations in prefrontal and medial temporal lobe cortex. Moreover, animal studies further implicate a role for the hippocampus in schema-based facilitation and in the emergence of prospective planning signals (...) following new learning. To date, convergence across the schema-enhanced learning and memory literature may be constrained by the predominant use of hippocampally dependent spatial navigation paradigms in rodents, and non-spatial list-based learning paradigms in humans. Here, we targeted this missing link by examining the effects of prior knowledge on human navigational learning in a hippocampally dependent virtual navigation paradigm that closely relates to foundational studies in rodents. Outside the scanner, participants overlearned Old Paired Associates (OPA – item-location associations) in multiple spatial environments, and they subsequently learned New Paired Associates (NPA – new item-location associations) in the environments while undergoing fMRI. We hypothesized that greater OPA knowledge precision would positively affect NPA learning, and that the hippocampus would be instrumental in translating this new learning into prospective planning of navigational paths to NPA locations. Behavioral results revealed that OPA knowledge predicted one-shot learning of NPA locations, and neural results indicated that one-shot learning was predicted by the rapid emergence of performance-predictive prospective planning signals in hippocampus. Prospective memory relationships were not significant in parahippocampal cortex and were marginally dissociable from the primary hippocampal effect. Collectively, these results extend understanding of how schemas impact learning and performance, showing that the precision of prior spatial knowledge is important for future learning in humans, and that the hippocampus is involved in translating this knowledge into new goal-directed behaviors.

In addition to its well‐known role as a coenzyme in oxidation–reduction reactions, the distinct role of NAD as a precursor for molecules involved in cell regulation has been clearly established. The involvement of NAD in these regulatory processes is based on its ability to function as a donor of ADP‐ribose; NAD synthesis is therefore required to avoid depletion of the intracellular pool. The rising interest in the biosynthetic routes leading to NAD formation and the highly conserved nature of the enzymes (...) involved prompted us to reconstruct the NAD biosynthetic routes operating in distinct eukaryotic organisms. The evidence obtained from biochemical and computational analysis provides a good example of how complex metabolic pathways may evolve. In particular, it is proposed that the development of several NAD biosynthetic routes during evolution has led to partial functional redundancy, allowing a given pathway to freely acquire novel functions unrelated to NAD biosynthesis.

This volume contains a selection of papers from the International Conference on Argumentation by prominent international scholars of argumentation theory. It provides an insightful cross-section of the current state of affairs in argumentation research. It will be of interest to all those working in the field of argumentation theory and to all scholars who are interested in recent developments in this field.

The South African government’s COVID-19 pandemic risk mitigation strategies significantly limited social contact, which necessitated a novel approach to existing face-to-face career guidance practices. The Grade 9 Career Guidance Project, originally developed as a group-based career development intervention, required radical adaptation into a self-directed, manualized format to offer career guidance to Grade 9 learners from low-income communities amid a global pandemic. The adaptation and continuation of the project was deemed essential as secondary school learners in low-income communities have limited career (...) guidance support. Furthermore, a close collaboration with the teachers at eight resource-constrained South African secondary schools was vital for successful implementation. To assess the success of the adaptation to a self-directed format, a mixed-methods design was employed, and Life Orientation teachers’ evaluative feedback was solicited. Favorable quantitative results were obtained; majority of teachers agreed that learners enjoyed the booklet and that it was deemed an adequate substitute to the previous contact-based format of the Career Guidance Project. This was also confirmed by the qualitative findings revealing teachers’ satisfaction with the booklet’s content, specifically that the booklet is complementary to the Life Orientation curriculum. Qualitative findings identified specific contextual barriers that contributed to some learners struggling to use the booklet optimally. The results suggest that it is feasible and acceptable to implement a self-directed career guidance intervention among secondary school learners amid a global pandemic. Teachers recommended ways to integrate the booklet, resources, and contact sessions as a preferred way forward. These findings have important implications for similar resource-constrained settings that may not have readily access to in-person career guidance and counseling human development. (shrink)

As part of the conference commemorating Theoria's 75th anniversary, a round table discussion on philosophy publishing was held in Bergendal, Sollentuna, Sweden, on 1 October 2010. Bengt Hansson was the chair, and the other participants were eight editors-in-chief of philosophy journals: Hans van Ditmarsch (Journal of Philosophical Logic), Pascal Engel (Dialectica), Sven Ove Hansson (Theoria), Vincent Hendricks (Synthese), Søren Holm (Journal of Medical Ethics), Pauline Jacobson (Linguistics and Philosophy), Anthonie Meijers (Philosophical Explorations), Henry S. Richardson (Ethics) and Hans Rott (Erkenntnis).

Responding to recent concerns about the reliability of the published literature in psychology and other disciplines, we formed the X-Phi Replicability Project to estimate the reproducibility of experimental philosophy. Drawing on a representative sample of 40 x-phi studies published between 2003 and 2015, we enlisted 20 research teams across 8 countries to conduct a high-quality replication of each study in order to compare the results to the original published findings. We found that x-phi studies – as represented in our sample (...) – successfully replicated about 70% of the time. We discuss possible reasons for this relatively high replication rate in the field of experimental philosophy and offer suggestions for best research practices going forward. (shrink)
