A survey of Euclid's Elements, this text provides an understanding of the classical Greek conception of mathematics and its similarities to modern views as well as its differences. It focuses on philosophical, foundational, and logical questions — rather than strictly historical and mathematical issues — and features several helpful appendixes.

The purpose of the present study was to investigate the effect and use of distributed practice in the context of self-regulated mathematical learning in high school. With distributed practice, a fixed learning duration is spread over several sessions, whereas with massed practice, the same time is spent learning in one session. Distributed practice has been proven to be an effective tool for improving long-term retention of verbal material and simple procedural knowledge in mathematics, at least when the practice schedule is (...) externally guided. In the present study, distributed practice was investigated in a context that required a higher degree of self-regulation. In total, 158 secondary school students were invited to participate. After motivational and cognitive characteristics of the students were assessed, the students were introduced to basic statistics, a topic of their regular curriculum. At the end of the introduction, the students could sign up for the study to further practice this content. Eighty-seven students did so and were randomly assigned either to the distributed or to the massed practice condition. In the distributed practice condition, they received three practice sets on three different days. In the massed practice condition, they received the same three sets, but all on one day. All exercises were worked in the context of self-regulated learning at home. Performance was tested two weeks after the last practice set. Only 44 students finished the study, which hampered the analysis of the effect of distributed practice. The characteristics of the students who completed the exercises were analyzed exploratory: The proportion of students who finished all exercises was significantly higher in the massed than in the distributed practice condition. Within the distributed practice condition, a significantly larger proportion of female students completed the exercises compared to male students. Additionally, among these female students, a larger proportion showed lower concentration difficulty. No such differential effects were revealed in the massed practice condition. Our results suggest that the use of distributed practice in the context of self-regulated learning might depend on learner characteristics. Accordingly, distributed practice might obtain more reliable effects in more externally guided learning contexts. (shrink)

This book represents a considerable revision and expansion of Public Choice II. Six new chapters have been added, and several chapters from the previous edition have been extensively revised. The discussion of empirical work in public choice has been greatly expanded. As in the previous editions, all of the major topics of public choice are covered. These include: why the state exists, voting rules, federalism, the theory of clubs, two-party and multiparty electoral systems, rent seeking, bureaucracy, interest groups, dictatorship, the (...) size of government, voter participation, and political business cycles. Normative issues in public choice are also examined including a normative analysis of the simple majority rule, Bergson–Samuelson social welfare functions, the Arrow and Sen impossibility theorems, Rawls's social contract theory and the constitutional political economy of Buchanan and Tullock.

Wilson et al. focus on one class of AGL tasks: the cognitively demanding task of detecting non‐adjacent dependencies (NADs) among items. They provide a typology of the different types of NADs in natural languages and in AGL tasks. A range of cues affect NAD learning, ranging from the variability and number of intervening elements to the presence of shared prosodic cues between the dependent items. These cues, important for humans to discover non‐adjacent dependencies, are also found to facilitate NAD learning (...) in several nonhuman animal species. (shrink)

Bayes’ formula is a fundamental statistical method for inference judgments in uncertain situations used by both laymen and professionals. However, since people often fail in situations where Bayes’ formula can be applied, how to improve their performance in Bayesian situations is a crucial question. We based our research on a widely accepted beneficial strategy in Bayesian situations, representing the statistical information in the form of natural frequencies. In addition to this numerical format, we used five visualizations: a 2×2-table, a unit (...) square, an icon array, a tree diagram, and a double-tree diagram. In an experiment with 688 undergraduate students, we empirically investigated the effectiveness of three graphical properties of visualizations: area-proportionality, use of discrete and countable statistical entities, and graphical transparency of the nested-sets structure. We found no additional beneficial effect of area-proportionality. In contrast, the representation of discrete objects seems to be beneficial. Furthermore, our results show a strong facilitating effect of making the nested-sets structure of a Bayesian situation graphically transparent. Our results contribute to answering the questions of how and why a visualization could facilitate judgment and decision making in situations of uncertainty. (shrink)

In a longitudinal naturalistic study, we observed German mothers interacting with their infants when they were 3 and 6 months old. Pursuing the idea that infants’ attention is socialized in everyday interactions, we explored whether eye contact is reinforced selectively by behavioral modification in the input provided to infants. Applying a microanalytical approach focusing on the sequential organization of interaction, we explored how the mother draws the infant’s attention to herself and how she tries to maintain attention when the infant (...) is looking at her. Results showed that eye contact is reinforced by specific infant-directed practices: interrogatives and conversational openings, multimodal stimulation, repetition, and imitation. In addition, these practices are contingent on the infant’s own behavior. By comparing the two data points (3 and 6 months), we showed how the education of attention evolves hand-in-hand with the developing capacities of the infant. Keywords: multimodal input; eye contact; interactional adaptation; ecology of attention; social learning. (shrink)

We investigated the causes and impact of procrastination on “slippery deadlines,” where the due date is ill-defined and can be autonomously extended, using the unique applied setting of grievance arbitration across two studies. In Study One, using 3 years of observed performance data derived from Canadian arbitration cases and a survey of leading arbitrators, we examined the effect of individual differences, self-regulatory skills, workloads and task characteristics on time delay. Observed delay here is a critical criterion, where justice is emphasized (...) to be swift and sure. Multilevel Modeling established trait procrastination as a substantive predictor of observed delay, equivalent to the environmental contributors of expediting the arbitration procedure or grievance complexity. Also, despite substantive negative consequence of delay for both arbitrators and their clients, arbitrators who scored one standard deviation above the mean in procrastination took approximately 83 days to write their decisions compared to the 26 days for arbitrators one standard deviation below the mean. In Study Two, we conducted a replication and extension survey with a much larger group of American arbitrators. Consistent with Temporal Motivation Theory, trait procrastination was largely explained by expectancy, value, and sensitivity to time related traits and skills, which together accounted for majority of the variance in trait procrastination, leaving little left for other explanations. For example, perfectionism connection to procrastination appears to be distal, being largely mediated by each of TMT’s core variables. Finally, procrastination was largely synonymous with a deadline pacing style, indicating that observed delay can be used as a proxy for procrastination as long as little or no prior work was done. In all, our results indicate that procrastination is rampant in the workplace and has seriously detrimental effects. (shrink)

The pathogenic microbe came to be a widely acknowledged “scientific fact” by the end of the 19th century. Taking the transfer of bacteriological knowledge to Warsaw as an example, this article contributes to understanding the question of how knowledge of bacteria was stabilized outside of its original place of production. Conceiving bacteriological knowledge as a laboratory practice it describes the techniques of mobilizing the “laboratory network” this practice depended on. The case of the Polish medical student Odo Bujwid transporting Robert (...) Koch’s and Louis Pasteur’s laboratory networks to Warsaw will be analyzed. Bujwid used literary and visual inscriptions to make these laboratory networks immutably mobile in Bruno Latour’s sense. But he also had to transport three-dimensional objects central to the networks’ functioning back to Warsaw. Personal exchange was, furthermore, essential to their successful transportation to the Polish kingdom. Next to Bujwid’s efforts to transform the laboratory networks into immutable mobiles, the analysis will extend the focus to mutable mobiles as well and will thus show that the successful stabilization of bacteriological knowledge in Warsaw was due not only to the immutability of its laboratory network but to its flexibility and elasticity as well.

Background Minimal research has been done to determine how well European nursing students understand the core principles of academic integrity and how often they deviate from good academic practice. Aim The aim of this study was to find out what educational needs nursing students have in terms of academic integrity. Research design A quantitative cross-sectional study in the form of a survey of nursing students was conducted via questionnaire in the fall of 2020. Participants The sample was composed of 79 (...) students in the BScN and MScN programs at Zürich University of Applied Sciences. Ethical considerations An application for a non-competence clearance was approved by the Ethics Committee in Zurich (BASEC No. Req-2020-00868). The survey was anonymous, and informed consent was obtained prior to participation. Results The participants had a high level of confidence in their own knowledge but were in many cases unable to correctly identify clear-cut examples of misconduct and to differentiate them from questionable practices. About 13% of the participants admitted that during their university education they had copied shorter passages from other sources into their own text without marking them as quotes. Conclusions The study documents extensive knowledge gaps among nursing students regarding both academic misconduct and questionable practices and indicates a need for improved academic integrity training.

I argue against Schroeder's explanation of pragmatic encroachment on knowledge. In section 1, I introduce pragmatic encroachment and point out that an explanation of it should avoid Pascalian considerations. In section 2, summarize the key aspects of Schroeder's explanation of pragmatic encroachment. In section 3, I argue that Schroeder's explanation faces a dilemma: it either allows for an objectionable form of Pascalian encroachment or it fails to be a fully general explanation of pragmatic encroachment.

I discuss the knowledge account of legal proof in Moss (2023) and develop an alternative. The unifying thread throughout this article are reflections on the beyond reasonable doubt (BRD) standard of proof. In Section 1, I will introduce the details of Moss’s account and how she motivates it via the BRD standard. In Section 2, I will argue that there are important disanalogies between BRD and knowledge that undermine Moss’s argument. There is however another motivation for the knowledge account: combined (...) with auxiliary claims, that is probabilistic knowledge and moral encroachment, it can provide a general solution to the puzzle of statistical evidence. Section 3 spells out the details. In Section 4, I suggest to combine the knowledge account with pragmatic encroachment, instead of moral encroachment, in order to stay clear of the thorny issues whether corporations have moral rights. In Section 5, I argue that the verdicts of Moss’s account in cases of false justified beliefs and non-luminous knowledge conflict with the BRD standard and thus call for abandoning the account. Based on the social function of the BRD standard, I suggest a replacement for the knowledge account that is also just as potent as a general solution for the puzzle of statistical evidence. While I will grant that knowledge is neither always necessary nor always sufficient for convictions, I will argue that the concept of knowledge nonetheless plays a significant and ineliminable role in legal decision-making.

Nietzsches Ausnahmestatus als Philosoph gründet nicht zuletzt in seinem künstlerischen Verhältnis zur Sprache. Der Grenzen sprengende Denker erweist sich zugleich als ein Grenzen sprengender Sprachartist, der den traditionellen Unterschied zwischen Philosophie und Dichtung zum Verschwimmen bringt. Während die Forschung meist den Hauptakzent auf den Denker Nietzsche legt, widmet sich der vorliegende Band dem Dichter Nietzsche. Untersucht wird ein großes, von der Forschung bislang erst ansatzweise erschlossenes Korpus von Gedichten und Gedichtfragmenten. Betrachtet werden darüber hinaus auch weitere literarische Ausdrucksformen Nietzsches sowie (...) ausgewählte Stationen seiner Rezeption als Dichter. (shrink)

Are we in a post-feminist era? Has the term, feminist, grown out of its resisted stance? What from today's standpoint is an appropriate concept of feminist philosophy?

The Protestant Church in East Germany played a decisive role in the peaceful overthrow of communism in the German Democratic Republic. As a shelter for action groups, as a champion of reformers, and as a voice for nonviolence, the church gave the people some where to meet, pray, talk, and eventually to unite in such numbers as to be a force of faith and justice which could no be resised.

Behavioural experiments are one of the central and most powerful methods of intervention in cognitive therapy. Yet until now, there has been no volume specifically dedicated to guiding physicians who wish to design and implement behavioural experiments across a wide range of clinical problems.The Oxford Guide to Behavioural Experiments in Cognitive Therapy fills this gap. It is written by clinicians for clinicians. It is a practical, easy to read handbook, which is relevant for practising clinicians at every level, from trainees (...) to cognitive therapy supervisors.Following a foreword by David Clark, the first two chapters provide a theoretical and practical background for the understanding and development of behavioural experiments. Thereafter, the remaining chapters of the book focus on particular problem areas. These include problems which have been the traditional focus of cognitive therapy, as well as those which have only more recently become a subject of study, and some which are still in their relative infancy. The book also includes several chapters on transdiagnostic problems, such as avoidance of affect, low self-esteem, interpersonal issues, and self-injurious behaviour. A final chapter by Christine Padesky provides some signposts for future development.Containing examples of over 200 behavioural experiments, this book will be of enormous practical value for all those involved in cognitive behavioural therapy, as well as stimulating exploration and creativity in both its readers and their patients.

This article analyzes whether Brandom’s ISA (inferential-substitutional-anaphoric) semantics as presented in Making It Explicit (MIE) and Articulating Reasons (AR) can cope with problems resulting from inferentialism’s near-implied meaning holism. Inferentialism and meaning holism entail a radically perspectival conception of content as significance for an individual speaker. Since thereby its basis is fixed as idiolects, holistic inferentialism engenders a communication-problem. Brandom considers the systematic difference in information among individuals as the „point“ of communication and thus doesn’t want to diminish these effects (...) of inferentialism. Instead, explains communication with a model of “navigating among perspectives without sharing contents”. The crucial element in this navigation-model is the functioning of anaphoric connections between tokens uttered in discourse that can be used by every individual speaker in their own perspectival semantic substitution-economies. The heart of Brandom’s semantics is the thesis of the purely inferential, hence non-referential nature of anaphora, coupled with the claim that anaphoric-inferential semantic mechanisms yield sufficient conditions for mutually successful “information-extraction” or interpretation. This article disputes the thesis and denies the claim. Regarding the former it is observed that all of Brandom’s plausible reconstructions of anaphoric discourse-structures rely on covert “reference-infiltrations” that can’t be eliminated. Regarding the latter, a new argument based on context-sensitive semantic phenomena in anaphoric settings shows that the crucial distinction between initiator or anaphoric antecedent and anaphoric dependent cannot be drawn according to Brandom’s own premises without overt and irreducible referential premises. The article concludes that either Brandom’s semantics can offer determinate contents, but then must accept genuinely referential semantic primitives, or else it leaves utterance-contents undeterminable and hence cannot explain communication.

In this commentary we challenge Fitouchi et al.'s puritanical morality account by presenting evidence showing (1) that pursuing harmless pleasures can actually support self-regulation, and (2) that sharing pleasurable experiences can foster cooperation. We conclude that puritanical morality is not as adaptive as presented, and may even suppress the potential benefits pleasure can have for the individual and society.

People with aphasia use gestures not only to communicate relevant content but also to compensate for their verbal limitations. The Sketch Model (De Ruiter, 2000) assumes a flexible relationship between gesture and speech with the possibility of a compensatory use of the two modalities. In the successor of the Sketch Model, the AR‐Sketch Model (De Ruiter, 2017), the relationship between iconic gestures and speech is no longer assumed to be flexible and compensatory, but instead iconic gestures are assumed to express (...) information that is redundant to speech. In this study, we evaluated the contradictory predictions of the Sketch Model and the AR‐Sketch Model using data collected from people with aphasia as well as a group of people without language impairment. We only found compensatory use of gesture in the people with aphasia, whereas the people without language impairments made very little compensatory use of gestures. Hence, the people with aphasia gestured according to the prediction of the Sketch Model, whereas the people without language impairment did not. We conclude that aphasia fundamentally changes the relationship of gesture and speech. (shrink)

ArgumentThe paper argues that epidemic surveillance and state-building were closely interconnected in interwar Poland. Starting from the paper technology of weekly epidemiological reporting it discusses how the reporting scheme of Polish epidemics came into being in the context of a typhus epidemic in 1919–20. It then shows how the statistics regarding nation-wide epidemics was put into practice. It is only when we take into account these practices that we can understand the epidemiological order the statistics produced. The preprinted weekly report (...) form registered Jews and Christians separately. Yet, the imagined national epidemiological space that emerged from it hardly took notice of this separation. Rather, the category that differentiated Polish epidemiological space in medical discourse was the capacity of contributing to the state-making practices of epidemic surveillance. This category divided Poland into two regions: a civilized and modern western region and a backward and peripheral eastern region. (shrink)

BackgroundAn analysis of the position statements of secular US medical and surgical professional societies on physician-assisted suicide (PAS) and euthanasia have not been published recently. Available statements were evaluated for position, content, and sentiment.MethodsIn order to create a comprehensive list of secular medical and surgical societies, the results of a systematic search using Google were cross-referenced with a list of societies that have a seat on the American Medical Association House of Delegates. Societies with position statements were identified. These statements (...) were divided into 5 categories: opposed to PAS and/or euthanasia, studied neutrality, supportive, acknowledgement without statement, and no statement. Linguistic analysis was performed using RapidMinder in order to determine word frequency and sentiment respective to individual statements. To ensure accuracy, only statements with word counts > 100 were analyzed. A 2-tailed independentttest was used to test for variance among sentiment scores of opposing and studied neutrality statements.ResultsOf 150 societies, only 12 (8%) have position statements on PAS and euthanasia: 11 for PAS (5 opposing and 4 studied neutrality) and 9 for euthanasia (6 opposing and 2 studied neutrality). Although the most popular words used in opposing and studied neutrality statements are similar, notable exceptions exist (suicide,medicine, andtreatmentappear frequently in opposing statements, but not in studied neutrality statements, whereaspsychologists,law, andindividualsappear frequently in studied neutrality statements, but not in opposing statements). Sentiment scores for opposing and studied neutrality statements do not differ (mean, 0.094 vs. 0.104;P = 0.90).ConclusionsFew US medical and surgical societies have position statements on PAS and euthanasia. Among them, opposing and studied neutrality statements share similar linguistic sentiment. Opposing and studied neutrality statements have clear differences, but share recommendations. Both opposing and studied neutrality statements cite potential risks of PAS legalization and suggest that good palliative care might diminish a patient’s desire for PAS. (shrink)

Public choice or rational politics differs from other approaches to the study of political behavior in that it builds on models in which rational individuals seek to advance their own interests. This five-part volume surveys the main ideas and contributions of the field. It contains twenty-five essays written by thirty scholars, both economists and political scientists, from North America and Europe. Part I discusses the nature and justification for the existence of government and various forms it can take, including mixed, (...) private, and public institutions, international organizations, federalisms, and constitutional governments. Part II examines the properties of different voting rules and preference aggregation procedures. Part III explores multiparty systems, interest groups, logrolling and political business cycles. The individual decisionmaker is the focus of Part IV, with surveys of the experimental literature on individual behavior, and why people vote as they do. The final section applies public-choice reasoning to bureaucracy, taxation, and the size of government. (shrink)
