In Germany, all-day care and all-day schooling are currently increasing on a large-scale. The extended time children spend in educational institutions could potentially result in limited access to nature experience for children. On the other hand, it could equally create opportunities for informal nature experience if school playgrounds have a specific nature-oriented design. This article is written from the perspective of a primary school teacher and presents the findings of a meta-analysis which looks at the impact nature experience has on (...) the development of children. Furthermore, the first results of a research study on green playgrounds in primary schools is discussed. The results so far seem to indicate that green school playgrounds have the potential of providing nature experience particularly for primary students. (shrink)

Natural experiments wherein preferred marriage partners are co-reared play a central role in testing the Westermarck hypothesis. This paper reviews two such hitherto largely neglected experiments. The case of the Karo Batak is outlined in hopes that other scholars will procure additional information; the case of the Oneida community is examined in detail. Genealogical records reveal that, despite practicing communal child-rearing, marriages did take place within Oneida. However, when records are compared with first-person accounts, it becomes clear (...) that, owing to age- and gender-segregating practices, most endogamously marrying individuals probably did not share a history of extensive propinquity.

Natural experiments are an increasingly popular research design in political science. This popularity raises a number of questions. First, what are natural experiments and why are they appealing? Second, what makes a good natural experiment? And finally, are natural experiments able to provide resources for knowledge production that other methodologies cannot or do not provide? Using Mary Morgan’s and Thad Dunning’s recent work on natural experiments, I offer answers to the first (...) two questions and use the analysis to argue that natural experiments highlight features of knowledge production that support methodological pluralism and the multiple aims of research.

In this systematic review, we summarized and evaluated the evidence for effects of, and associations between, immersive nature-experience on mental, physical and social health promotion outcomes. Immersive nature-experience was operationalized as non-competitive activities, both sedentary and active, occurring in natural environments removed from everyday environments. We defined health according to the World Health Organization’s holistic and positive definition of health and included steady-state, intermediate, and health promotion outcomes. An electronic search was performed for Danish, English, German, Norwegian, and Swedish (...) articles published between January 2004 and May 2017. Manual approaches, e.g., bibliographies from experts, supplemented the literature search. Data were extracted from 461 publications that met the inclusion criteria. To assess the status and quality of the evidence for health promotion effects of immersive nature-experience, we focused on the subset of studies based on controlled designs (n = 133). Outcome level quality of the evidence was assessed narratively. Interventions most often involved adventure-based activities, short-termed walking, and seated relaxation in natural environments. We found positive effects on a range of health promotion outcomes grouped under psychological wellbeing (n = 97; ≈55% positive; ≈13% mixed; ≈29% non-significant; 2% negative); psychosocial function (n = 67; ≈61% positive; ≈9% mixed; ≈30% non-significant); psychophysiological stress response (n = 50; ≈58% positive; ≈18% mixed; ≈24% non-significant), and cognitive performance (n = 36; ≈58% positive; ≈6% mixed; ≈33% non-significant; 3% negative); and social skills and relationships (n = 34; ≈70% positive; ≈7% mixed; ≈22% non-significant). Findings related to outcomes categorized under physical health, e.g., risk of cardiovascular disease, were less consistent (n = 51; ≈37% positive; ≈28% mixed; ≈35% non-significant). Across the types of interventions and outcomes, the quality of the evidence was deemed low and occasionally moderate. In the review, we identify, discuss, and present possible solutions to four core methodological challenges associated with investigating immersive nature-experience and health outcomes: 1) intervention and program complexity; 2) feasibility and desirability of randomization; 3) blinding of participants and researchers; and 4) transferability and generalizability. The results of the review have been published as a popular-scientific report and a scientific research overview, both in Danish language. (shrink)

Initiatives advocating for nature-based solutions, such as increased urban biodiversity, aim to promote public health as a part of creating sustainable cities. These initiatives are supported by a plenitude of scientific literature demonstrating the link between human health and nature contact. Despite these findings, positive human-nature interactions are declining worldwide, negatively effecting human development and health. We support an embodied approach to mental health. Taking this approach seriously illuminates how cities can be enhanced by modifying environmental and social affordances and (...) the ways in which urban dwellers interact with urban natural greenspaces. We argue that urban nature experiences can be used to promote mental health, but that indicators of environmental injustice need to addressed. (shrink)

Stephen Jay Gould argued that replaying the ‘tape of life’ would result in radically different evolutionary outcomes. Recently, biologists and philosophers of science have paid increasing attention to the theoretical importance of convergent evolution—the independent origination of similar biological forms and functions—which many interpret as evidence against Gould’s thesis. In this paper, we examine the evidentiary relevance of convergent evolution for the radical contingency debate. We show that under the right conditions, episodes of convergent evolution can constitute valid natural (...) experiments that support inferences regarding the deep counterfactual stability of macroevolutionary outcomes. However, we argue that proponents of convergence have problematically lumped causally heterogeneous phenomena into a single evidentiary basket, in effect treating all convergent events as if they are of equivalent theoretical import. As a result, the ‘critique from convergent evolution’ fails to engage with key claims of the radical contingency thesis. To remedy this, we develop ways to break down the heterogeneous set of convergent events based on the nature of the generalizations they support. Adopting this more nuanced approach to convergent evolution allows us to differentiate iterated evolutionary outcomes that are probably common among alternative evolutionary histories and subject to law-like generalizations, from those that do little to undermine and may even support, the Gouldian view of life.

A natural experiment was conducted studying the relations among student cheating, motivation, religiosity, and attitudes toward cheating. Students enrolled in a dual religious/college curriculum were surveyed regarding their cheating behavior, attitudes toward cheating, religiosity, and learning/grade motivations toward classes. Business and liberal arts college students were represented. Results strongly support the following conclusions. First, grade orientation is associated with increases in self-reported cheating. Second, among these religious students, more religiosity correlates with reduced reports of cheating in all courses. This (...) result appears to be due to the unique effect of religion on self-reported cheating rates and, depending on course content, on a reduction of grade orientation in religious students. Third, business students report more cheating than their liberal arts counterparts, even when taking the same courses. They have less critical attitudes toward cheating and greater grade orientation, both of which statistically contribute to this difference, but other factors are involved as well. Keywords: academic integrity, motivation, religiosity, cheating. (shrink)

Natural selection is commonly interpreted as the fundamental mechanism of evolution. Questions about how selection theory can claim to be the all-sufficient explanation of evolution often go unanswered by today's neo-Darwinists, perhaps for fear that any criticism of the evolutionary paradigm will encourage creationists and proponents of intelligent design.In Biological Emergences, Robert Reid argues that natural selection is not the cause of evolution. He writes that the causes of variations, which he refers to as natural experiments, (...) are independent of natural selection; indeed, he suggests, natural selection may get in the way of evolution. Reid proposes an alternative theory to explain how emergent novelties are generated and under what conditions they can overcome the resistance of natural selection. He suggests that what causes innovative variation causes evolution, and that these phenomena are environmental as well as organismal.After an extended critique of selectionism, Reid constructs an emergence theory of evolution, first examining the evidence in three causal arenas of emergent evolution: symbiosis/association, evolutionary physiology/behavior, and developmental evolution. Based on this evidence of causation, he proposes some working hypotheses, examining mechanisms and processes common to all three arenas, and arrives at a theoretical framework that accounts for generative mechanisms and emergent qualities. Without selectionism, Reid argues, evolutionary innovation can more easily be integrated into a general thesis. Finally, Reid proposes a biological synthesis of rapid emergent evolutionary phases and the prolonged, dynamically stable, non-evolutionary phases imposed by natural selection. (shrink)

This article explores the characteristics of research sites that scientists have called “natural experiments” to understand and develop usable distinctions for the social sciences between “Nature’s or Society’s experiments” and “natural experiments.” In this analysis, natural experiments emerge as the retro-fitting by social scientists of events that have happened in the social world into the traditional forms of field or randomized trial experiments. By contrast, “Society’s experiments” figure as events in the (...) world that happen in circumstances that are already sufficiently “controlled” to be open for direct analysis without reconstruction work.

The problem of academic dishonesty is as old as it is widespread – dating back millennia and perpetrated by the majority of students. Attempts to promote academic integrity, by comparison, are relatively new and rare – stretching back only a few hundred years and implemented by a small fraction of schools and universities. However, the past decade has seen an increase in efforts among universities to promote academic integrity among students, particularly through the use of online courses or tutorials. Previous (...) research has found this type of instruction to be effective in increasing students’ knowledge of academic integrity and reducing their engagement in academic dishonesty. The present study contributes to this literature with a natural experiment on the effects of the Academic Integrity Course (AIC) at The University of Auckland, which became mandatory for all students in 2015. In 2012, a convenience sample of students (n= 780) had been asked to complete a survey on their perceptions of the University’s academic integrity polices and their engagement in several forms of academic dishonesty over the past year. In 2017, the same procedures and survey were used to collect data from second sample of students (n= 608). After establishing measurement invariance across the two samples on all latent factors, analysis of variance revealed mixed support for the studies hypotheses. Unexpectedly, students who completed the AIC (i.e., the 2017 sample) reported: (1) significantly lower (not higher) levels of understanding, support, and effectiveness with respect to the University’s academic integrity policies; (2) statistically equivalent (not higher) levels of peer disapproval of academic misconduct, and; (3) significantly higher (not lower) levels of peer engagement in academic misconduct. However, results related to participants’ personal engagement in academic misconduct offered partial support for hypotheses – those who completed the AIC reported significantly lower rates of engagement on three of the eight behaviors included in the study. The implications and limitations of these findings are discussed as well as possible future directions for research. (shrink)

Many theorists in epistemology and mind accept externalism with respect to content—namely, the claim that the conditions that individuate mental content are external to the occurrence of that content as a mental fact. Whatever it is that distinguishes a pain in the knee from a pain in the toe—or, alternatively, whatever it is that makes it possible for the subject to discriminate this pain as a pain in the knee from that pain as a pain in the toe—are factors and (...) conditions located in the physical and external world. This much externalism seems to be required even if one is a thoroughly entrenched mentalist. This “content externalism” is captured, fairly effectively, by the more traditional distinction between concepts and percepts. What is then asserted by the mentalist is that concepts have their source or origin in the external world, but the perceptual content does not. Perceptual content can be identified in different ways which are: the view that identifies the distinguishing feature of the perceptual with qualia, a position not far removed from the Lockean distinction between Primary and Secondary qualities; or, the perceptual might also be characterized in terms of representationalism, where qualia are an essential part of the representational medium, but where the representational medium contains conceptual content as well. In either case, the perceptual is Type and/or Token distinct from whatever is the external physical conditions or states of affairs causally responsible for the occurrence of either the conceptual content or the perceptual content. An argument for the claim that percepts are essential and necessary is that, without such percepts, there can be no experience. It is doubtful. (shrink)

Corporate misconduct receives significant attention in the business ethics literature. This paper studies how corporate misconduct is impacted by import penetration from China, which is largely exogenous to the U.S. product market. Using this natural experiment, we find that heightened Chinese import penetration curbs corporate misconduct of U.S. firms. The effect is more pronounced for firms with weaker corporate governance and firms more vulnerable to product market competition. The findings provide implications for firms facing increased import penetration. Firms may (...) consider improving corporate governance and exploring avenues for differentiation as potential strategies to cope with the competition. In addition, we address the exogeneity concern derived from the influence of Chinese value penetration. Furthermore, we find that competition-related policies such as tariff reduction and U.S. granting China Permanent Normal Trade Relations (PNTR) status also lower corporate misconduct. Our work adds to the debates on competition and corporate misconduct in a cross-country competitive landscape. (shrink)

This study examines the impact of mandatory Corporate Social Responsibility reporting on firms’ financial reporting quality using a quasi-natural experiment in China that mandates a subset of firms to report their CSR activities starting in 2008. We find that mandatory CSR disclosure firms constrain earnings management after the policy. The result is robust to a battery of sensitivity tests and more prominent for firms with lower analyst coverage. Further analyses reveal that upward earnings management by mandatory disclosure firms is (...) more likely to be caught after the policy. The findings suggest that mandatory CSR disclosure mitigates information asymmetry by improving financial reporting quality. (shrink)

The purpose of this paper is to present the results of a natural experiment involving academic cheating by university students. We explore the relationship of moral judgment to actual behavior, as well as the relationship between the honesty of students self-reports and the extent of cheating. We were able to determine the extent to which students actually cheated on the take-home portion of an accounting exam. The take-home problem was not assigned with the intent of inducing cheating among students. (...) However, the high rate of observed cheating prompted the instructor to return to class and ask the students to provide information on their motivation. The students' responses are the data analyzed in this natural experiment. We found that in a simple regression the relationship between moral judgment scores and cheating behavior was insignificant. However, when we tested whether including Utilizer scores affected the relationship of cheating and moral judgment we found that Utilizer affected the relationship significantly. Finally, we found that moral judgment and honesty were not related, but higher levels of cheating behavior related to less honesty. (shrink)

The Organization Department of the Communist Party of China announced the Opinions on Further Regulation on Party and Political Leaders and Cadres Working Part-Time in Enterprises to force the resignation of government officials holding the position of independent director in listed companies. This paper empirically examines the impact of the GID resignation on firm performance using a difference-in-differences model, which is an exogenous event with a “natural experiment.” The study finds that after the promulgation of the Opinions, firms that (...) lose some of their political resources and their corporate performance decreases significantly compared to firms that do not experience GID resignations. A good external governance environment, while somewhat weakening, is not sufficient to offset the negative impact of the loss of political resources on firm performance. This paper further explores the mechanism by which the GID resignation affects firm performance: one important way in which the resignation of GIDs cause the loss of political resources on which the firm's development depends is that the loss of the firm's tax benefits after GID resignation directly leads to a decline in performance; it also leads to a reduction in the firm's financial subsidy income and a reduction in the amount of bank loans, but both of these do not have a significant effect on the decline in firm performance. The study suggests that GIDs play more of a resource-providing “official” role than an “independent director's” supervisory and advisory role in Chinese listed companies. The findings of this paper reveal the phenomenon of “Political-Business Spin” in China, which has some implications for developing countries, represented by China, to improve the independence of the board of directors and the corporate governance.

Debt-ridden corporate growth and increased vulnerability was one of the causes of the 1997 financial crisis in Korea. Introduction of the outside director system has been the core part of the board reforms following the crisis. Our estimation using instruments obtained from a natural experiment illustrates that outside monitoring has improved capital structure of firms even when we control for the leverage regulation effect, enhanced compliance with leverage regulation and thus reduced business risks, and reduced excessive growth and excessive (...) investment more consistently for the top 10 largest chaebols than non-chaebol firms and smaller sized chaebol affiliates. Our results shed some light on why existing studies report the positive effect of outsiders on firm value and add value to existing agency theory by illustrating that the effect of improved governance on capital structure could be non-linear.

Hempel’s account of thought experiments has been discussed only by a very few authors and, for the most part, with rather cursory remarks. Its importance, however, is not only historical, but also systematic theoretical, because it involves the distinction between discovery and justification, a main pillar of neopositivistic philosophy of science. Hempel raised the question whether thought experiments constitute a methodological component of scientific research or, on the contrary, are merely a heuristic-psychological device for obtaining and/or transmitting new (...) ideas. While conceding a few exceptions in the natural sciences, he argued that thought experiments always have a heuristic character in the social sciences. There is however a fundamental tension in Hempel’s conception of thought experiments, between the thesis of methodological monism and the neopositivistic dichotomy discovery/justification. On the one hand, on the basis of the unity of scientific method, Hempel admits a difference only in degree between the natural and the human sciences, but on the other hand, he draws a principled distinction between thought experiments of the human sciences (which have only a greater or lesser heuristic value) and those of the natural sciences (which may have also a cognitive-justificatory value). If one assumes the unity of method in the minimal sense in which no scientific knowledge can renounce intersubjective controllability, this tension can be removed either by rejecting the discovery/justification dichotomy or by interpreting it differently. Here, following the second path, two senses of the dichotomy are distinguished, one of which must be accepted, while the other rejected. This removes the internal tension in Hempel’s conception of thought experiments and suggests the thesis that any plausible thought experiment, both in the natural and the human sciences, must already contain some justification, implicit or explicit, of the theoretical hypotheses that they formulate.

This article studies how financial investors respond to firms' corporate social responsibility (CSR) performance in terms of their investing behaviors, and how such behaviors change contingent on an event that provokes their attention and concerns to CSR. Using the melamine contamination incident in China as a natural experiment, it is found that neither the individual investors' nor the institutional investors' behaviors are influenced by firms' CSR performance before the incident. Nevertheless, in the post-event period, institutional investors' behaviors are significantly (...) influenced by firms' CSR performance that exceeds a certain threshold. Furthermore, such an effect diminishes for a better CSR performance. In comparison, the authors do not find any effects of CSR performance on individual investors, either before the event or after the event. Finally, firms' performance and investors' behaviors jointly affect firms' stock returns after the event but not before the event. This article reconciles the mixed findings in the literature on the effect of firms' CSR performance on their financial performance by showing that such an effect exists in a contingent manner. Furthermore, the authors show that a too low or a too high CSR performance could lead to undesirable responses from investors. Therefore, managers should pay attention to optimizing firms' CSR activities. (shrink)

Emotive-factive predicates, such as surprise or be happy, are a source of empirical and theoretical puzzles in the literature on embedded questions. Although they embed wh-questions, they seem not to embed whether-questions. They have complex interactions with negative polarity items such as any or even, and they have been argued to preferentially give rise to weakly exhaustive readings with embedded questions. We offer an empirical overview of the situation in three experiments collecting acceptability judgments, monotonicity judgments, and truth-value judgments. (...) The results straightforwardly confirm the special selectional properties of emotive-factive predicates. More interestingly, they reveal the existence of strongly exhaustive readings for surprise. The results also suggest that the special properties of emotive-factives cannot be solely explained by their monotonicity profiles, because they were not found to differ from the profiles of other responsive predicates.

Interactions with social robots are symbolic experiences guided by the pretense that robots depict real people. But they can also be natural experiences that are direct, automatic, and independent of any thoughtful mapping between what is real and depicted. Both experiences are important, both may apply within the same interaction, and they may vary within a person over time.

ObjectivesTo compare changes in the number and amount of payments received by orthopedic and non-orthopedic surgeons from industry between 2014 and 2017.MethodsUsing the Centers for Medicare and Medicaid Services (CMS) Open Payment database from 2014 to 2017, we conducted a retrospective cohort study of industry payments to surgeons, including general payments and research payments.ResultsAmong orthopedic surgeons, the total number of general payments decreased from 248,698 in 2014 to 241,966 in 2017, but their total value increased from $97.1 million in 2014 (...) to $110.2 million in 2017. Among non-orthopedic surgeons, the total number decreased from 604,884 in 2014 to 582,490 in 2017, while the total value remained stable at approximately $159 million. Between 2014 and 2017, there was a differential increase in the median number of general payments received by non-orthopedic when compared to orthopedic surgeons (incidence rate ratio, 1.09; 95% CI, 1.08–1.09; p < 0.001), but a differential decline in the median value of general payments (− 8.9%; 95% CI, − 9.5%, − 8.4%; p < 0.001). Findings were consistent when stratified by nature of payment. In contrast, between 2014 and 2017, there was neither a differential change in the median number nor median value of research payments received by non-orthopedics.ConclusionExamination of a natural experiment of prior public disclosure of payments to orthopedic surgeons suggests that the Physician Payment Sunshine Act was associated with an increase in the number, but a decline in the value, of general payments received by non-orthopedic surgeons, but not on research payments received.

The goal of this paper is to answer the following question: Does it make sense to speak of thought experiments not only in physics, but also in mathematics, to refer to an authentic type of activity? One may hesitate because mathematics as such is the exercise of reasoning par excellence, an activity where experience does not seem to play an important role. After reviewing some results of the research on thought experiments in the natural sciences, we turn (...) our attention to experiments and thought experiments in mathematics, especially in fundamental mathematics, and investigate what thought experiments can teach us there. If we accept the principle that mathematical practice can sometimes be best described by a pragmatist approach where the concept of experience in mathematics is considered from a new perspective, thought experiments can in some cases be a useful instrument different from both ‘mathematical experiments’ and ‘formal’ proofs: they are mathematical experiments using deviant methods.

Thought experiments are widely used in the informal explanation of Relativity Theories; however, they are not present explicitly in formalized versions of Relativity Theory. In this paper, we present an axiom system of Special Relativity which is able to grasp thought experiments formally and explicitly.

To a large extent, the evidential base of claims in the philosophy of science has switched from thought experiments to case studies. We argue that abandoning thought experiments was a wrong turn, since they can effectively complement case studies. We make our argument via an analogy with the relationship between experiments and observations within science. Just as experiments and ‘natural’ observations can together evidence claims in science, each mitigating the downsides of the other, so too (...) can thought experiments and case studies be mutually supporting. After presenting the main argument, we look at potential concerns about thought experiments, suggesting that a judiciously applied mixed-methods approach can overcome them. (shrink)

We investigate the impact of informal arguments on judgments about thought experiment cases in light of Deutsch and Cappelen’s mischaracterization view, which claims that philosophers’ case judgments are primarily based on arguments and not intuitions. If arguments had no influence on case judgments, this would seriously challenge whether they are, or should be, based on arguments at all—and not on other cognitive sources instead, such as intuition. In Experiment 1, we replicated Wysocki’s (Rev Philos Psychol 8(2):477–499, 2017) pioneering study on (...) a Gettier-style case, and we confirmed that the informal arguments used by him had no significant effect. However, we also included an improved argument for ascribing knowledge, which did have a significant effect even in Wysocki’s original design. We therefore followed up with Experiment 2 on three Gettier-style cases, where we used a more natural dialogical format for presenting both case descriptions and informal arguments. Overall, we found a clear impact of prima facie good pro and con arguments on case judgments. The issue of argument impact is thus no obstacle to arguing about thought experiments. (shrink)

Biomedical deployments of data science capitalise on vast, heterogeneous data sources. This promotes a diversified understanding of what counts as evidence for health-related interventions, beyond the strictures associated with evidence-based medicine. Focusing on COVID-19 transmission and prevention research, I consider the epistemic implications of this diversification of evidence in relation to: (1) experimental design, especially the revival of natural experiments as sources of reliable epidemiological knowledge; and (2) modelling practices, particularly the recognition of transdisciplinary expertise as crucial to (...) developing and interpreting data models. Acknowledging such shifts in evidential, experimental and modelling practices helps avoid harmful applications of data-intensive methods. (shrink)

Evolutionary models can explain the dynamics of populations, how genetic, genotypic, or phenotypic frequencies change with time. Models incorporating chance, or drift, predict specific patterns of change. These are illustrated using classic work on blood types by Cavalli-Sforza and his collaborators in the Parma Valley of Italy, in which the theoretically predicted patterns are exhibited in human populations. These data and the models display properties of ensembles of populations. The explanatory problem needs to be understood in terms of how likely (...) an observed change, in either a population or an ensemble, would be under drift alone; this is fundamentally a matter of chance. Understood in this way, issues of drift and chance undercut most recent philosophical, but not biological, discussions of the role of "genetic drift.". (shrink)

While psychologists and political scientists have long investigated issues of interest to philosophers, the development of political experimental philosophy has remained limited. This slow progress is surprising, given that political philosophers commonly acknowledge the relevance of empirical data for normative theorizing. In this chapter, we illustrate the importance of empirical data by outlining recent developments in three domains related to theories of justice, where empirical results reinforce or endanger popular philosophical theories. Our first showcase concerns the boundaries of the concept (...) of fairness. While both libertarian thinkers and social egalitarians have united in rejecting the concept of natural injustice, we show that people do consider that unpreventable natural inequalities can be described as unfair. Second, we take the example of impartiality devices, such as the veil of ignorance or the idea of an impartial spectator, to show that such devices are efficient at shifting people’s intuitions in a more impartial manner. Third, we review empirical data on fairness intuitions to show that people conform to a pluralist theory of justice, valuing desert, needs-satisfaction, and equality at the same time. However, distribution according to desert enjoys a privileged position: people mostly care for the satisfaction of basic needs of deserving recipients, and people are willing to tolerate large inequalities in meritocratic contexts. The centrality of desert leads to dilemmas for mainstream egalitarian theorists, as theories that do not recognize the value of desert could fail to find support or legitimacy within the population.

In recent years, the Audit Pilot of Natural Resources Assets (APNRA) pilot program has been implemented by the Chinese government to strengthen the protection of natural resources and the ecological environment. Based on the APNRA pilot program, we use the multi-period differences–in–differences model to investigate the response of corporate environmental responsibility to external governance pressure. We find that firms significantly improve their environmental investment and performance after the implementation of the APNRA pilot program. Sewage charges (including green fees) (...) and ecological protection incentives constitute the two main channels that explain the positive relationship. We further find that the impact of the program on corporate environmental investment and performance is more pronounced for firms in regions with poor environmental quality, and for firms in heavy-polluting industries. This paper introduces the role of government governance in generating positive externality for firms and provides a valuable understanding of environmental governance in an emerging market. (shrink)

I provide some considerations on scientific thought experiments, focusing on their epistemic value. First, I outline the distinctive features of scientific thought experiments, provide some historical background and, as an illustration, describe two thought experiments: Galileo's on falling bodies and Stevin's on inclined plane. I take thought experiments in physics as an example from which more general conclusions can be drawn - about thought experiments in other natural sciences, but also in philosophy, mathematics, and (...) other sciences. Further, I present Kuhn's epistemic puzzle as well as some proposed solutions. This closely relates to the question what kind of processes are involved in scientific thought experimenting. The satisfactory answer must consider scientific discoveries. I outline the mental model account as the most promising account since it best incorporates the findings of cognitive science. I conclude with two issues that the account needs to resolve and the role cognitive science can play in this. (shrink)

Bioethics: 50 Puzzles, Problems, and Thought Experiments collects 50 cases—both real and imaginary—that have been, or should be, of special interest and importance to philosophical bioethics. Cases are collected together under topical headings in a natural order for an introductory course in bioethics. Each case is described in a few pages, which includes bioethical context, a concise narrative of the case itself, and a discussion of its importance, both for broader philosophical issues and for practical problems in clinical (...) ethics and health policy. Each entry also contains a brief, annotated, list of suggested readings. In addition to the classic cases in bioethics, the book contains discussion of cases that involve several emerging bioethical issues: especially, issues around disability, social justice, and the practice of medicine in a diverse and globalized world.

Against Norton's claim that all thought experiments can be reduced to explicit arguments, I defend Brown's position that certain thought experiments yield a priori knowledge. They do this, I argue, not by allowing us to perceive “Platonic universals” (Brown), even though they may contain non-propositional components that are epistemically indispensable, but by helping to identify certain tacit presuppositions or “natural interpretations” (Feyerabend's term) that lead to a contradiction when the phenomenon is described in terms of them, and (...) by suggesting a new natural interpretation in terms of which the phenomenon can be redescribed free of contradiction.

My dissertation philosophically analyzes experiments in evolutionary biology, an area of science where experimental approaches have tended to supplement, rather than supercede more traditional approaches, such as field observations. I conduct the analysis on the basis of three case studies of famous episodes in the history of selection experiments: H. B. D. Kettlewell's investigations of industrial melanism in the Peppered Moth, Biston betularia; two of Th. Dobzhansky's studies of adaptive radiation in the fruit fly, Drosophila pseudoobscura; and M. (...) Wade's studies of group selection in the flour beetle, Tribolium castaneum. The case studies analyze the arguments and evidence these investigators used to identify the respective roles of experiments and other forms of inquiry in their investigations. I discuss three philosophical issues. ;First, the analysis considers whether these selection experiments fit models of experimentation developed in the context of micro-and high energy physics by Allan Franklin and Peter Galison . My analysis documents that the methods used in the case studies can be accommodated on both Franklin and Galison's views. I conclude the case studies do not support claims regarding the relative autonomy of biology. ;Second, the analysis documents a number of important roles for life history data acquired by strictly observational means in the process of experimentation, from identification of research problems and development of experimental designs to interpretation of results. Divorced from this context experiments in biology make no sense. Thus, in principle, experimental approaches cannot replace more traditional methods. ;Third, the analysis examines a superficial tension between the use of experiments, which I characterize by the presence of artificial intervention, and the stated goal of most investigations in evolutionary biology, that of understanding how systems behave in the absence of intervention. Experiments involve trade-offs between the control one has over the circumstances of the study and how informative the study is with regard to questions of interest to biologists regarding specific, actual systems in nature. Experimental simulations of natural phenomena in other historical sciences involve similar trade-offs, but there are reasons for believing this tension is more prominent in biology. (shrink)

THIS VOLUME owcs its existence to the suggestion and the persuasive insistence of my friend and colleague Justus Buchler... the unpublished papers dealing with "the theory of history" and “the theory of nature” bulked large enough to form a volume in themselves. Hence the volume appears ...with [these] essays in philosophic analysis of two themes that have for some years been central in my own interests. -/- Each of the two Parts deals with a unified theme, and the two together (...) not only exhibit, it is hoped, a consistent philosophic attitude and approach, but also treat two different aspects of what is a common metaphysical inquiry. Aside from the prologue and the epilogue, none of these papers has appeared in this form before... History and nature together offer the great challenge to the philosophic mind.

In the television show Deal or No Deal a contestant is endowed with a sealed box, which potentially contains a large monetary prize. In the course of the show the contestant learns more information about the distribution of possible monetary prizes inside her box. Consider two groups of contestants, who learned that the chances of their boxes containing a large prize are 20% and 80% correspondingly. Contestants in both groups receive qualitatively similar price offers for selling the content of their (...) boxes. If contestants are less risk averse when facing unlikely gains, the price offer is likely to be more frequently rejected in the first group than in the second group. However, the fraction of rejections is virtually identical across two groups. Thus, contestants appear to have identical risk attitudes over (large) gains of low and high probability. (shrink)

The relation between logic and thought has long been controversial, but has recently influenced theorizing about the nature of mental processes in cognitive science. One prominent tradition argues that to explain the systematicity of thought we must posit syntactically structured representations inside the cognitive system which can be operated upon by structure sensitive rules similar to those employed in systems of natural deduction. I have argued elsewhere that the systematicity of human thought might better be explained as resulting from (...) the fact that we have learned natural languages which are themselves syntactically structured. According to this view, symbols of natural language are external to the cognitive processing system and what the cognitive system must learn to do is produce and comprehend such symbols. In this paper I pursue that idea by arguing that ability in natural deduction itself may rely on pattern recognition abilities that enable us to operate on external symbols rather than encodings of rules that might be applied to internal representations. To support this suggestion, I present a series of experiments with connectionist networks that have been trained to construct simple natural deductions in sentential logic. These networks not only succeed in reconstructing the derivations on which they have been trained, but in constructing new derivations that are only similar to the ones on which they have been trained.

Enterprises are the market players for carbon reductions and carbon trading, and they are also the significant driving force in a low-carbon economy and society. Using the data of A-share listed companies from 2010 to 2016, this study uses a difference-in-differences model to examine the effects of the low-carbon city construction on corporate carbon reduction performance. Consistent with our hypotheses, we find that the low-carbon city construction promotes corporate carbon reduction performance. Further analysis indicates that the policy effect is stronger (...) for state-owned enterprises than non-state-owned enterprises. Moreover, environmental quality can affect the promotion of local government officials, which is more prominent in pilot low-carbon cities, and political promotion incentives significantly improve corporate carbon reduction performance. Furthermore, the highest emission reduction effects come in the fourth year after adopting a carbon reduction policy and are concentrated among the firms in the eastern region. Overall, our findings offer a new point view for a deeper understanding of the improvement of corporate carbon reduction performance, and provide microscopic evidence for the objective evaluation of the environmental effects of China's low-carbon city pilot policies.

Focusing solely on the near-death cognizance of the dying, rather than the material perspective of the living, reveals a new understanding of death. Its significance to psychology, philosophy, and religion is huge for what emerges is a long overlooked phenomenon: a nonsupernatural, relativistic, and timelessly eternal consciousness, which can be a natural afterlife. Ironically, the validity of the theory of a natural eternal consciousness (NEC) assumes the loss of all materially based consciousness with death—more specifically, the permanent loss (...) of time perception. The theory claims, and the article deduces from empirical knowledge, that by imperceptibly entering the timelessness before death, one’s last conscious moment, whatever the type, becomes by default—psychologically, from one’s perspective—a forever present moment. To help explain and validate the theory, the article presents thought experiments and a formal model of all of life’s moments and all transitions between periods of time perception and those of timelessness. An open-minded reading should reveal that the NEC does not threaten faith in a god or a heaven. (shrink)

By investigating conceptions of experience from Descartes to Kant, this book shows that one of the central questions of the early-modern period was how humans can instantiate in their actions the principles of rational moral agency, while at the same time responding with their bodies to the causal play of nature. Through the analysis of this question, the book draws attention to the bodily underpinnings of the ability to experience thoughts and feelings. It thus challenges overly subjectivist interpretations that concentrate (...) on the inner realm of the experiencing mind and because of this fail to account for the worldly dimension of being experientially responsive to the affections of the body.
