Multivariate pattern analysis can reveal new information from neuroimaging data to illuminate human cognition and its disturbances. Here, we develop a methodological approach, based on multivariate statistical/machine learning and time series analysis, to discern cognitive processing stages from functional magnetic resonance imaging (fMRI) blood oxygenation level dependent (BOLD) time series. We apply this method to data recorded from a group of healthy adults whilst performing a virtual reality version of the delayed win-shift radial arm maze (RAM) task. This task has (...) been frequently used to study working memory and decision making in rodents. Using linear classifiers and multivariate test statistics in conjunction with time series bootstraps, we show that different cognitive stages of the task, as defined by the experimenter, namely, the encoding/retrieval, choice, reward and delay stages, can be statistically discriminated from the BOLD time series in brain areas relevant for decision making and working memory. Discrimination of these task stages was significantly reduced during poor behavioral performance in dorsolateral prefrontal cortex (DLPFC), but not in the primary visual cortex (V1). Experimenter-defined dissection of time series into class labels based on task structure was confirmed by an unsupervised, bottom-up approach based on Hidden Markov Models. Furthermore, we show that different groupings of recorded time points into cognitive event classes can be used to test hypotheses about the specific cognitive role of a given brain region during task execution. We found that whilst the DLPFC strongly differentiated between task stages associated with different memory loads, but not between different visual-spatial aspects, the reverse was true for V1. Our methodology illustrates how different aspects of cognitive information processing during one and the same task can be separated and attributed to specific brain regions based on information contained in multivariate patterns of voxel activity.

As more professors implement critical thinking training in their classrooms, these professors not only must teach the process of critical thinking, but they must also instruct students about how to effectivelyuse their newly acquired skills. Because critical thinking tends to promote reconsideration of strong personal beliefs, students may be resistant to change, resulting in various kinds of emotions. In addition, students who have been trained to in critical thinking may experience resistance from friends and family, leading to greater interpersonal conflict. (...) Therefore, professors should strive for greater sensitivity and understanding, responding to students’ personal needs by teaching them how to effectively and appropriately use their critical thinking skills in various environments.

In this article, we focus on the concept of leadership ethics and make observations about transformational, transactional and servant leadership. We consider differences in how each definition of leadership outlines what the leader is supposed to achieve, and how the leader treats people in the organization while striving to achieve the organization's goals. We also consider which leadership styles are likely to be more popular in organizations that strive to maximize short run profits. Our paper does not tout or degrade (...) any of these leadership theories. Instead, it points out which theories allow reason to play more than a minimal role in ethical decision-making, as well as those that are most consistent with a firm's desire to achieve efficiency in the short run. We explain our view that the way leadership is practiced in large, bureaucratic organizations suggests that ethics is often absent from the leader's decision-making process. Consequently, we suggest that before we engage in a meaningful dialogue about what kind of leaders we might really want in business, we must consider how much short-run profit we are willing to forego in exchange for more ethical corporate cultures.

Epistemic entrenchment, as presented by Gärdenfors and Makinson (1988) and Gärdenfors (1988), is a formalisation of the intuition that, when forced to choose between two beliefs, an agent will giveup the less entrenched one. While their formalisation satisfactorilycaptures the intuitive notion of the entrenchment of beliefs in a number ofaspects, the requirement that all wffs be comparable has drawn criticismfrom various quarters. We define a set of refined versions of theirentrenchment orderings that are not subject to the same criticism, andinvestigate (...) the relationship between the refined entrenched orderings,the entrenchment orderings of Gärdenfors and Makinson, and AGM theorycontraction (Alchourrón et al., 1985). To conclude, we compare refinedentrenchment with two related approaches to epistemic entrenchment. (shrink)

In aging humans, aerobic exercise interventions have been found to be associated with more positive or less negative changes in frontal and temporal brain areas, such as the anterior cingulate cortex (ACC) and hippocampus, relative to no-exercise control conditions. However, individual measures such as gray-matter (GM) probability may afford less reliable and valid conclusions about maintenance or losses in structural brain integrity than a latent construct based on multiple indicators. Here, we established a latent factor of GM structural integrity based (...) on GM probability assessed by voxel-based morphometry, magnetization transfer saturation, and mean diffusivity. Based on this latent factor, we investigated changes in structural brain integrity during a six-month exercise intervention in brain regions previously reported in studies using volumetric approaches. Seventy-five healthy, previously sedentary older adults aged 63–76 years completed an at-home intervention study in either an exercise group (EG;n= 40) or in an active control group (ACG;n= 35). Measures of peak oxygen uptake (VO2peak) taken before and after the intervention revealed a time-by-group interaction, with positive average change in the EG and no reliable mean change in the ACG. Significant group differences in structural brain integrity changes were observed in the right and left ACC, right posterior cingulate cortex (PCC), and left juxtapositional lobule cortex (JLC). In all instances, average changes in the EG did not differ reliably from zero, whereas average changes in the ACG were negative, pointing to maintenance of structural brain integrity in the EG, and to losses in the ACG. Significant individual differences in change were observed for right ACC and left JLC. Following up on these differences, we found that exercising participants with greater fitness gains also showed more positive changes in structural integrity. We discuss the benefits and limitations of a latent-factor approach to changes in structural brain integrity, and conclude that aerobic fitness interventions are likely to contribute to brain maintenance in old age.

Generalisations of theory change involving operations on arbitrary sets ofwffs instead of on belief sets (i.e., sets closed under a consequencerelation), have become known as base change. In one view, a base should bethought of as providing more structure to its generated belief set, whichmeans that it can be employed to determine the theory contraction operationassociated with a base contraction operation. In this paper we follow suchan approach as the first step in defining infobase change. We think of an infobase (...) as a finite set of wffs consisting of independently obtainedbits of information. Taking AGM theory change (Alchourrón et al. 1985) as the general framework, we present a method that uses the structure of aninfobase B to obtain an AGM theory contraction operation for contractingthe belief set Cn(B). Both the infobase and the obtained theory contraction operation then play a role in constructing a unique infobasecontraction operation. Infobase revision is defined in terms of an analogueof the Levi Identity, and it is shown that the associated theory revisionoperation satisfies the AGM postulates for revision. Because every infobaseis associated with a unique infobase contraction and revision operation, the method also allows for iterated base change. (shrink)

Meaningful relationships are centrally important for human functioning. It remains unclear, however, which aspects of meaningful relationships impact wellbeing the most and whether these differ between psychiatric patients and members of the community. Information about relationship attributes and functions were collected in community members and psychiatric patients. Relationship attributes and functions were examined for differences between groups, their impact on wellbeing and symptoms, and the size of network. Community members reported fewer relationships, higher frequency of contact and less desire for (...) change when compared to the psychiatric patients. Nevertheless, both groups reported relatively high levels of fulfilled functions. Quality of the relationship and investment into the relationship was associated with both wellbeing and symptoms for both the community and the patient group. Almost all functions were associated with wellbeing and symptoms for the community group. However, for the patient group, only few functions were associated with wellbeing and no functions were associated with symptoms. Contrary to our hypotheses, the results show that psychiatric patients do not have a deficit in fulfilling relationships. Most people report a well-functioning network of meaningful, high-quality relationships. Patients benefit from meaningful, function-fulfilling relationships just as much as community members. Results are discussed with respect to how targeting relationships can be used clinically. (shrink)

In her book Victims' Stories and the Advancement of Human Rights, Diana Meyers offers a careful analysis of victims' stories as a narrative genre, and she argues that stories in this genre function as a call to care: they both depict a moral void and issue a moral demand, thereby fostering the development of a culture of human rights. This article, while finding Meyers's articulation of this idea compelling, questions Meyers's account of how victims' stories do their moral work. Whereas (...) Meyers argues that victims' stories are complete narratives, characterized by a distinctive form of closure, it suggests that the moral power of victims' stories may lie in part in their open-endedness or lack of closure. In telling their stories, victims engage their audiences in a new moral relationship and implicitly give them a role to play in bringing about the moral closure they seek. (shrink)

This paper addresses three commentaries on Victims' Stories and the Advancement of Human Rights. In response to Vittorio Bufacchi, it argues that asking victims to tell their stories needn't be coercive or unjust and that victims are entitled to decide whether and under what conditions to tell their stories. In response to Serene Khader, it argues that empathy with victims' stories can contribute to building a culture of human rights provided that measures are taken to overcome the implicit biases and (...) colonialist interpellations she identifies. In response to Andrea Westlund, it proposes a taxonomy of types of narrative closure and offers some arguments to strengthen her view that empathy with victims' stories endows audience members with a new reason and new motivation to support human rights.

The philosopher of chemistry Andrea Woody has recently published a wide-ranging article concerning the turn to practice in the philosophy of science. Her primary example consists of the use of different forms of representations by Lothar Meyer and Mendeleev when they presented their views on chemical periodicity. Woody believes that this distinction can cast light on various issues including why Mendeleev was able to make predictions while Meyer was not. Secondly, she claims that it can clarify the much-debated (...) question concerning the relative values of prediction and accommodation of data in the way that the periodic system was accepted. Thirdly, Woody believes that such differences in the representation of periodicity can be used to argue for the explanatory nature of the periodic table in contrast with the more traditional view that the periodic table is not explanatory.

Andreas Stokke presents a comprehensive study of lying and insincere language use. He investigates how lying relates to other forms of insincerity and explores the kinds of attitudes that go with insincere uses of language. -/- Part I develops an account of insincerity as a linguistic phenomenon. Stokke provides a detailed theory of the distinction between lying and speaking insincerely, and accounts for the relationship between lying and deceiving. A novel framework of assertion underpins the analysis of various kinds (...) of insincere speech, including false implicature and forms of misleading with presuppositions, prosodic focus, and semantic incompleteness. -/- Part II sets out the relationship between what is communicated and the speaker's attitudes. Stokke develops the view of insincerity as a shallow phenomenon that is dependent on conscious attitudes rather than deeper motivations. The various of ways of speaking while being indifferent toward what one communicates are covered, and the phenomenon of 'bullshitting' is distinguished from lying and other forms of insincerity. Finally, an account of insincere uses of interrogative, imperative, and exclamative utterances is also given. (shrink)

Climate change can be interpreted as a unique case of historical injustice involving issues of both intergenerational and global justice. We split the issue into two separate questions. First, how should emission rights be distributed? Second, who should come up for the costs of coping with climate change? We regard the first question as being an issue of pure distributive justice and argue on prioritarian grounds that the developing world should receive higher per capita emission rights than the developed world. (...) This is justified by the fact that the latter already owns a larger share of benefits associated with emission generating activities because of its past record of industrialisation. The second question appears to be an issue of compensatory justice. After defining what we mean by compensation, we show that different kinds of compensatory principles run into problems when used to justify payments by historical emitters of the North to people suffering from climate change in the South. As an alternative, we propose to view payments from wealthy countries for adaptation to climate change in vulnerable countries rather as a measure based on concerns of global distributive justice.

Whether meaning is compositional has been a major issue in linguistics and formal philosophy of language for the last 2 decades. Semantic holism is widely and plausibly considered as an objection to the principle of semantic compositionality therein. It comes as a surprise that the holistic peculiarities of scientific language have been rarely addressed in formal accounts so far, given that semantic holism has its roots in the philosophy of science. For this reason, a model-theoretic approach to semantic holism in (...) the language of science is presented here. This approach preserves compositionality to a large extent. *Received September 2009; revised February 2010. †To contact the author, please write to: Seminar for Philosophy, Logic, and Theory of Science, Hauspostfach 49, Ludwig-Maximilians-Universität, Munich 80539, Germany; e-mail: holger.andreas@lrz.uni-muenchen.de.

A simple explanation of theoreticity says that a term is theoretical if and only if it refers to nonobservational entities. Paradigmatic examples of such entities are electrons, neutrinos, gravitational forces, genes etc. There is yet another explanation of theoreticity: a theoretical term is one whose meaning becomes determined through the axioms of a scientific theory. The meaning of the term ‘force’, for example, is seen to be determined by Newton’s laws of motion and further laws about special forces, such as (...) the law of gravitation. Theoreticity is a property that is commonly applied to both expressions in the language of science, and referents and concepts of such expressions. Objects, relations and functions as well as concepts thereof may thus qualify as theoretical in a derived sense. (shrink)

This article explores how neutralisation can explain people's lack of commitment to buying Fair Trade products, even when they identify FT as an ethical concern. It examines the theoretical tenets of neutralisation theory and critically assesses its applicability to the purchase of FT products. Exploratory research provides illustrative examples of neutralisation techniques being used in the FT consumer context. A conceptual framework and research propositions delineate the role of neutralisation in explaining the attitude-behaviour discrepancies evident in relation to consumers' FT (...) purchase behaviour, providing direction for further research that will generate new knowledge of consumers' FT purchase behaviour and other aspects of ethical consumer behaviour.

Background It is a common ethical challenge for ambulance clinicians to care for patients with impaired decision-making capacities while assessing and determining the degree of decision-making ability and considering ethical values. Ambulance clinicians’ ethical competence seems to be increasingly important in coping with such varied ethical dilemmas. Ethics rounds is a model designed to promote the development of ethical competence among clinicians. While standard in other contexts, to the best of our knowledge, it has not been applied within the ambulance (...) service context. Thus, the aim of this study was to describe ambulance clinicians’ experiences of participating in ethics rounds. Methods This was a qualitative descriptive study, evaluating an intervention. Data were collected through sixteen interviews with ambulance clinicians who had participated in an intervention involving ethics rounds. The analysis was performed by use of content analysis. Results Two themes describe the participants’ experiences: (1) Reflecting freely within a given framework, and (2) Being surprised by new insights. The following categories form the basis of the themes; 1a) Gentle guidance by the facilitator, 1b) A comprehensible structure, 2a) New awareness in the face of ethical problems, and 2b) Shared learning through dialogue. Conclusion Incorporating structured ethics rounds seems to create a continuous development in ethical competence that may improve the quality of care in the ambulance service. Structured guidance and facilitated group reflections offer ambulance clinicians opportunities for both personal and professional development. An important prerequisite for the development of ethical competence is a well-educated facilitator. Consequently, this type of ethics rounds may be considered a useful pedagogical model for the development of ethical competence in the ambulance service. (shrink)

Relational egalitarianism is a theory of justice according to which people must relate as equals. However, not just any inegalitarian relation is unjust, i.e., the fact that parents do not relate as equals to their children is not unjust. Whereas an adult treating another adult paternalistically is objectionable from the point of view of relational egalitarianism, parent-child paternalism is not. What may explain this difference in judgment? I refer to this as the Puzzle. I discuss four justifications of the Puzzle (...) and argue that none of them is satisfactory. In the final part of the paper, I discuss where this leaves relational egalitarianism as a theory of justice. (shrink)

Many philosophers believe that there exist distinctive obstacles to relying on moral testimony. In this paper, I criticize previous attempts to identify these obstacles and offer a new theory. I argue that the problems associated with moral deference can't be explained in terms of the value of moral understanding, nor in terms of aretaic considerations related to subjective integration. Instead, our uneasiness with moral testimony is best explained by our attachment to an ideal of authenticity that places special demands on (...) our moral beliefs. (shrink)

This paper defends a version of the realist view that fictional characters exist. It argues for an instance of abstract realist views, according to which fictional characters are roles, constituted by sets of properties. It is argued that fictional names denote individual concepts, functions from worlds to individuals. It is shown that a dynamic framework for understanding the evolution of discourse information can be used to understand how roles are created and develop along with story content. Taking fictional names to (...) denote individual concepts provides accounts of a number of uses of fictional names. These include non-fictional uses, fictional uses, metafictional uses, interfictional uses, counterfictional uses, and negative existentials. It is argued that this account is not open to objections that have been raised in the literature. (shrink)

Responsibility as accountability is normally taken to have stricter control conditions than responsibility as attributability. A common way to argue for this claim is to point to differences in the harmfulness of blame involved in these different kinds of responsibility. This paper argues that this explanation does not work once we shift our focus from other-directed blame to self-blame. To blame oneself in the accountability sense is to feel guilt and feeling guilty is to suffer. To blame oneself in the (...) attributability sense, it will be argued, is to feel shame and feeling shame is also to suffer. The different control conditions cannot be explained by a difference in the harm of blame. Instead, this paper argues that accountability and attributability are governed by different kinds of appropriateness: an agent S is accountability blameworthy for X only if S deserves to feel guilty; an agent S is attributability blameworthy for X only if it is fitting that S feels shame for X.

Upon discovering that certain beliefs we hold are contingent on arbitrary features of our background, we often feel uneasy. I defend the proposal that if such cases of contingency anxiety involve defeaters, this is because of the epistemic significance of disagreement. I note two hurdles to our accepting this Disagreement Hypothesis. Firstly, some cases of contingency anxiety apparently involve no disagreement. Secondly, the proposal may seem to make our awareness of the influence of arbitrary background factors irrelevant in determining whether (...) to revise our beliefs. I show that each of these problems can be successfully accommodated by the Disagreement Hypothesis. (shrink)

This paper tries to explain why racial profiling involves a serious injustice and to do so in a way that avoids the problems of existing philosophical accounts. An initially plausible view maintains that racial profiling is pro tanto wrong in and of itself by violating a constraint on fair treatment that is generally violated by acts of statistical discrimination based on ascribed characteristics. However, consideration of other cases involving statistical discrimination suggests that violating a constraint of this kind may not (...) be an especially serious wrong in and of itself. To fully capture the significant wrong that occurs when racial profiling is targeted at black Americans or other similarly situated groups, it is argued that we should appeal to the idea that this basic injustice is exacerbated when it forms part of a larger pattern of similar actions that collectively realize a state of cumulative injustice.
