Testimonial accounts of mathematical problem choice typically rely on intrinsic constraints. They focus on the worth of the problem and feelings of beauty.

This paper describes the way in which a certain representation of basic scientific knowledge can be coupled with traditional microeconomic analysis to provide an analysis of rational research planning or agenda setting in basic science. Research planning is conceived as a resource allocation decision in which resources are being allocated to activities directed towards the solution of basic scientific problems. A structuralist representation of scientific knowledge is employed to provide a relatively precise characterization of a basic scientific problem.

Based on data from a survey of biological scientists at 125 American universities, this article explores how the commercialization of the university affects the problems academic scientists pursue and argues that this reorientation of scientific agendas results in a shift from science in the public interest to science for private goods. Drawing on perspectives from Bourdieu on how actors employ strategic practices toward the accumulation of social capital and acquire dispositional and perceptional tendencies that in turn recondition social structures, the (...) commercialization of the university is construed not as something that ‘‘happens to,’’ but rather something that ‘‘happens through’’ academic scientists. The specific shape and direction of the commercialization of the university is therefore influenced by how scientists incorporate the new resources and social relations of commercialization into their scientific practice and how their creative engagement with shifting structural conditions remakes the culture of academic science.

This paper explores some issues about the choice of variables for causal representation and explanation. Depending on which variables a researcher employs, many causal inference procedures and many treatments of causation will reach different conclusions about which causal relationships are present in some system of interest. The assumption of this paper is that some choices of variables are superior to other choices for the purpose of causal analysis. A number of possible criteria for variable choice are described and (...) defended within a broadly interventionist approach to causation. (shrink)

The problem of rational theory-choice is the problem of whether choice of theory by a scientist may be objectively rational in the absence of an invariant scientific method. In this paper I offer a solution to the problem, but the solution I propose may come as something of a surprise. For I wish to argue that the work of the very authors who have put the rationality of such choice in question, Thomas Kuhn and (...) Paul Feyerabend, contains all that is needed to solve the problem.

Most political liberals argue that only rules, policies and institutions that are part of society’s basic structure need to be justified with so-called public reasons. Laws enacted outside this set are legitimate if and when public reasons can justify the procedure that selects them. I argue that this view is susceptible to known problems from social choice theory. However, there are resources within political liberalism that could address them. If the scope of public reason is extended beyond the basic (...) structure it could order people’s preferences in a way that circumvents the identified issues. (shrink)

Choice experiment (CE) is a questionnaire based method that the accuracy of research questionnaire determines the validity of the research outcomes. Attribute selection has a prime importance in every CE studies. If respondents do not understand or do not have preference for a certain attribute, the attribute non-attendance problem might happen that biases overall results of the research. Qualitative approaches such as literature review, focus group discussion, and in depth discussion commonly applied in CE researches. However, especially in (...) the developing countries context where ethnical and cultural diversity is a challenge in conducting survey based questionnaires, qualitative methods are not sufficient in selecting attributes. Present study investigates the application of relative importance index (RII) in respondents¡¯ preference for attributes in a modal shift study in Klang Valley, Malaysia. The 5 point Likert scale questions were employed to enhance respondents¡¯ preferences for initial 24 selected attributes. The results of this study showed that from 24 pre-selected attributes, only 18 of them had RII>0.5 and could be included in the final CE design. The results of this study could help researchers to control for unobserved problems in selecting the attributes which could not be discovered through qualitative approaches. -/- . (shrink)

This paper tries to explain how individuals manage adaptive individual choice (i.e., the decision to acquire a fitter than average behavior or idea rapidly and tractably) in cultural evolution, despite the fact that acquiring fitness information is very difficult. I argue that the means of solving this problem suggested in the cultural evolution literature largely are various types of decision rules employing representations of fitness correlated properties or states of affairs. I argue that the problem of adaptive (...) individual choice is best solved where some of these learning rule representations are socially transmitted and some are biologically transmitted. (shrink)

_ Source: _Page Count 19 In this paper, we tackle the contribution that history of science can make to the _problem of rule-choice_, i.e., the choice from among competing methodological rules. Taking our cue from Larry Laudan’s writings, we extensively discuss what we call _historicist naturalism_, i.e., the view that history of science plays a pivotal role in the justification of rules, since it is one source of the evidence required to settle methodological controversies. As we illustrate, there are (...) cases of rule-choice that depend on conceptual considerations alone, and in which history of science does not factor. Moreover, there are cases in which methodological change is prompted – and explained – by empirical information that is not historical in nature: as suggested by what we call _scientific naturalism_, the justification of methodological choices comes from our knowledge of the structure of the world, as expressed by our currently accepted scientific theories. As we argue, due to its backward-looking character, historicist naturalism does not satisfactorily deal with the case of newly introduced rules, for which no evidence concerning their past performance is available. In sum, we conclude, the contribution that history of science can make to rule-choice is more modest than Laudan suggests. (shrink)

Numerous authors indicate that the influence of academic education extends beyond the growth of specialized knowledge gained by the graduates. Scholars are trying to identify and examine the potential impact of higher learning on students’ attitudes and choices. One of the dimensions considered by the researchers is the effect of university training on students’ moral choices. Our paper attempts to identify differences between the students’ declared moral choices and their majors (fields of studies). Working with a sample of university students (...) of Economics and Sociology (N = 181), and using three variants of the Trolley Problem, the subjects’ responses are used to identify the similarities and differences between their choices. The participants were asked to respond to three hypothetical situations regarding a runaway trolley. Their decision in the first scenario could save a person’s life or let her be run over by the trolley. In the second scenario, their decision could either let one person die and save five lives or save one life and let five people be killed. These two scenarios required pulling a lever to switch the trolley from one track to another. The third scenario requires pushing an obese person in front of the runaway trolley to stop it from killing five persons. As expected, we found a significant difference between the two groups (the economists and the sociologists) in the case of our third scenario, however, we found no evidence supporting the indoctrination hypothesis. We conclude that the existing differences between the choices made by the future economists and sociologists may support the preselection hypothesis. (shrink)

If indeterminism is to be necessary for moral responsibility, we must show that it doesn’t preclude responsibility (the Luck Problem) and that it might enhance it (the Enhancement Problem). A ‘strong luck claim’ motivates the Luck Problem: if an agent’s choice is undetermined, then her mental life will be causally irrelevant to her choice, whichever way she decides. A ‘weak luck claim’ motivates the Enhancement Problem: if an agent’s choice is undetermined, then even (...) if her mental life is causally relevant to her choice, whichever way she decides, we cannot explain how she _settles_ her choice. Only the weak luck claim is plausible. However, its plausibility depends on our accepting that we could only settle our choices if they are settled by additional exercises of agency. If we instead understand the process of settling decisions in procedural terms, we can begin to sketch a solution to the Enhancement Problem. (shrink)

The close association of particular races with particular classes invites a means to exhibit disdain for a race via class. Class and race do not simply occupy a list of social problems, because generally, specific races correlate with particular classes. Racism is presently unacceptable, but not classism. We may feel sympathy for the poor, but we do not refrain from disdain. The disdain of the poor centers on Neoclassical economics’ insistence on choice in regards to class. The language of (...) choice does not circumscribe race. Michel Foucault’s work illustrates that the persistent correlation of race and class is not merely sociological but conceptual. Such close associations of particular races with particular classes serve as a means to generate essentialisms that express racism through classism. (shrink)

Throughout the world, female students are less likely than males to take advanced physics courses. This mixed-methods study uses a concurrent, nested design to study an online homework intervention designed to address choice and achievement. A choice of three different contexts (biological, sports, and traditional) were offered to students for each physics problem, intending to stimulate females’ interest and enhance achievement. Informed by aspects of Artino’s social-cognitive model of academic motivation and emotion, we investigated: Which context of (...) physics problems do males and females select?; What explanations do students give for their choices?; Are there differences in the achievement of males and females?; and Is there a relationship between student achievement and the context selected? Fifty-two high school physics students from five U.S. states participated. Data included pre and post Force Concept Inventory scores, homework context choices and achievement, and rationales for choices. Findings indicate that females were most likely to select biology contexts; males, traditional. All students made more attempts on video questions over word questions, although females did not score as well. For all questions, students generally persisted until they answered them correctly, with females taking fewer attempts on problems. Context choice was mostly driven by interest, for males, and perceptions of difficulty level for females; however, rationales were indistinguishable by gender. On their first homework question attempt, females scored significantly better than the males. Initially, males had significantly higher FCI scores; post homework intervention, females increased their mean scores significantly on the FCI, erasing the initial gender gap, with no growth nor decline in males’ scores. Females with FCI growth were equally as likely to choose biology contexts as traditional contexts; males were more likely to choose biology contexts. Findings from this study suggest that modest changes to homework problems that provide choice and make the physics problems more contextually interesting - even without changes in classroom instruction - could increase interest and motivation students and increase achievement for both male and female students. Recommendations will be discussed. (shrink)

This inquiry focuses on the problem of human freedom in the thought of Augustine and two of his early critics, John Cassian and Faustus of Riez. Two issues are of primary importance: the issue concerning the nature of free choice of will, and the issue concerning how free choice of will is to be reconciled with divine election. These issues arise as a result of a change that occurred in Augustine's thinking on human freedom in 396, the (...) year that he grasped the true significance of Paul's doctrine of divine election. To Augustine that doctrine entailed that the will's movement towards the Good was only possible if divine Good Itself worked within the fallen will to make it good. Cassian and Faustus, however, questioned how Augustine could affirm the reality of free choice of will when he insisted that the fallen moral agent lacked the natural ability to do good. ;In order to come to terms with this dilemma, this inquiry views Augustine's later doctrine of human freedom as a form of classical Christian compatibilism. Beginning with H. A. Wolfson's observation that in the Pelagian Controversy Augustine Christianized the pagan Stoic doctrine of fate, the study seeks to develop the implications of this observation in the context of the semi-Augustinian Controversy . Thus it attempts to carry out a task that Wolfson himself had intended to undertake but had never in fact been able to accomplish. ;In keeping with this objective, the inquiry develops Wolfson's claim by situating Augustine's response to the semi-Augustinians against the background of two key texts: Cicero's De fato and Augustine's De civitate dei . A careful study of these texts indicates not only a remarkable similarity between Chrysippus' and Augustine's solution to the problem of human freedom but also Augustine's own awareness of his indebtedness to the Stoics. With this background in mind, the inquiry proceeds, initially, to unravel Augustine's doctrine of human freedom and, subsequently, to view it in relation to Cassian's and Faustus' doctrine of human freedom. After drawing out the implications of these three doctrines of human freedom, a concluding chapter calls attention to the fact that Stoicism exerted a much more pervasive influence on the development of Augustine's doctrine of human freedom than has hitherto been suspected.

Most agree that, if all else is equal, patients should be provided with enough information about proposed medical therapies to allow them to make an informed decision about what, if anything, they wish to receive. This is the principle of informed choice; it is closely related to the notion of informed consent. Contemporary clinical trials are analysed according to classical statistics. This paper puts forward the argument that classical statistics does not provide the right sort of information for informing (...) choice. The notion of probability used by classical statistics is complex and difficult to communicate. Therapeutic decisions are best informed by statistical approaches that assign probabilities to hypotheses about the benefits and harms of therapies. Bayesian approaches to statistical inference provide such probabilities. (shrink)

An agent often does not have precise probabilities or utilities to guide resolution of a decision problem. I advance a principle of rationality for making decisions in such cases. To begin, I represent the doxastic and conative state of an agent with a set of pairs of a probability assignment and a utility assignment. Then I support a decision principle that allows any act that maximizes expected utility according to some pair of assignments in the set. Assuming that computation (...) of an option's expected utility uses comprehensive possible outcomes that include the option's risk, no consideration supports a stricter requirement. (shrink)

There is a strong moral presumption against the use of coercion, and those who are coerced seem to be less responsible for the actions they were coerced to perform. Both these considerations seem to reflect the effect of coercion on the victim’s choice. This paper examines three ways of understanding this effect. First, I argue against understanding victims as unable to engage in genuine action. Next, I consider the suggestion that victims are unable to consent to participate in the (...) coercer’s plan. Although this suggestion is promising, I argue that the inability to consent reflects a more basic problem. Victims are unable to exercise what I call ‘normative authority’: they are unable to make discretionary changes in the permissions and obligations that they and others have. This final account yields a compelling understanding of why coercion is impermissible when it is and reveals a unique way in which impermissible coercion affects the responsibility of victims.

We examined how children’s strategy choices in solving complex subtraction problems are related to grade and to variations in problem complexity. In two studies, third- and fifth-grade children (N≈160 each study) solved multi-digit subtraction problems (e.g., 34 - 18) and described their solution strategies. In the first experiment, strategy selection was investigated by means of a free-choice paradigm, whereas in the second study a discrete-choice approach was implemented. In both experiments, analyses of strategy repertoire indicated that third-grade (...) children were more likely to report less-efficient strategies (i.e., counting) and relied more on the right-to-left solution algorithm compared to fifth-grade children who more often used efficient memory-based retrieval and conceptually-based left-to-right (i.e., decomposition) strategies. Nevertheless, all strategies were reported or selected by both older and younger children and strategy use varied with problem complexity and presentation format for both age groups. These results supported the overlapping waves model of strategy development and provide detailed information about patterns of strategy choice on complex subtraction problems. (shrink)

In many decision scenarios, one has to choose an element from a set S given some reference point e. For the case where S is a subset of a Euclidean space, we axiomatize the choice method that selects the point in S that is closest to e. © 1999 Elsevier Science B.V. All rights reserved.

In Bermúdez 2013 I argued against David Lewis’s well-known and widely accepted claim that Newcomb’s problem and the prisoner’s dilemma are really notational variants of a single problem. Mark Walker’s paper in this journal takes issue with my argument. In this note I show how Walker’s criticisms are misplaced. The problems with Walker’s argument point to more general and independently interesting conclusions about, first, the relation between deliberation and decision and, second, the differences between the prisoner’s dilemma, which (...) is a strategic choice problem, and Newcomb’s problem, which is a parametric choice problem.

The problem of theory choice and model selection is hard but still important when useful truths are underdetermined, perhaps not by all kinds of data but by the kinds of data we can have access to ethically or practicably—even if we have an infinity of such data. This article addresses a crucial instance of that problem: the problem of inferring causal structures from nonexperimental, nontemporal data without assuming the so-called causal Faithfulness condition or the like. A (...) new account of epistemic evaluation is developed to solve that problem and justify a standard practice of causal inference in data science. (shrink)

There are arguments for determinism. Admittedly, this is opposed by the fact of everyday experience of autonomy. In the following, it is argued for the compatibility of determinism and autonomy. Taking up considerations of Donald MacKay, a fatalistic attitude can be refuted as false. Repeatedly, attempts have been made to defend the possibility of autonomy with reference to quantum physical indeterminacy. But its statistical randomness clearly misses the meaning of autonomy. What is decisive, on the other hand, is the possibility (...) of knowledge, which opens up opportunities for planning, freedom of choice and ultimately 'self-choice'. Results of neurobiological research, especially Benjamin Libet's and more recently John-Dylan Haynes', seem to refute this: Actions are unconsciously initiated before conscious decision. But, as Libet has also shown, consciousness always has the possibility of a veto – and thus also of knowledge-driven action control. Ultimately, the idea of possible self-choice can thus become the determining condition. Only such a form of rational self-determination establishes a spiritual identity and at the same time represents the maximum of autonomy possible for human beings. (shrink)

St. Augustine’s De Libero Arbitrio is by far the most important of the saint’s philosophical works. Although he wrote it fairly soon after his conversion and before the Pelagian controversy broke out, he had no need to change his views in later life, but continued to recommend that it should be read. In spite of its title, it is not a discussion on the nature of free will, nor an analysis of the psychological circumstances in which choice is exercised. (...) The author himself tells us, in his Retractations, that it was written to answer the Manichaean objection to Christianity that, since the presence of evil is undeniable, it is inconceivable that God can be both almighty and infinitely good. The saint in his reply traced evil to sin, and sin to free will. Hence the title of this book. Since it was written before Pelagianism arose, there was no need to go into the difficulties of grace and free will, so the treatise is philosophical rather than theological. It contains the fullest exposition in any of his writings of his proof from reason for the existence of God, and in setting out the argument he deals with some of the deepest problems in philosophy.

A question that has been largely overlooked by philosophers of religion is how God would be able to effect a rational choice between two worlds of unsurpassable goodness. To answer this question, I draw a parallel with the paradigm cases of indifferent choice, including Buridan's ass, and argue that such cases can be satisfactorily resolved provided that the protagonists employ what Otto Neurath calls an ‘auxiliary motive’. I supply rational grounds for the employment of such a motive, and (...) then argue against the views of Leibniz and Nicholas Rescher to show that this solution would also work for God. (shrink)

Making adaptive choices between solution strategies is a central element of contemporary mathematics education. However, previous studies signal that students make suboptimal choices between mental and written strategies to solve division problems. In particular, some students of a lower math ability level appear inclined to use mental strategies that lead to lower performance. The current study uses a pretest-training-posttest design to investigate the extent to which these students’ choices for written strategies and performance may be increased. Sixth graders of below-average (...) mathematics level (N = 147) participated in one of two training conditions: an explicit-scaffolding training designed to promote writing down calculations or a practice-only training where strategy use was not explicitly targeted. Written strategy choices and performance increased considerably from pretest to posttest for students in both training conditions, but not in different amounts. Exploratory results suggest that students’ strategy choices may also be affected by their attitudes and beliefs and the sociocultural context regarding strategy use. (shrink)
