We introduce a new solution for tournaments called the unsurpassed set. This solution lies between the uncovered set and the Copeland winner set. We show that this solution is more decisive than the uncovered set in discriminating among alternatives, and avoids a deficiency of the Copeland winner set. Moreover, the unsurpassed set is more sensitive than the uncovered set but less sensitive than the Copeland winner set to the reinforcement of the chosen alternatives. Besides, it turns out that this solution (...) violates the other standard properties including independence of unchosen alternatives, stability, composition consistency and indempotency. (shrink)

Surprisingly little has been written about hedged assertion. Linguists often focus on semantic or syntactic theorizing about, for example, grammatical evidentials or epistemic modals, but pay far less attention to what hedging does at the level of action. By contrast, philosophers have focused extensively on normative issues regarding what epistemic position is required for proper assertion, yet they have almost exclusively considered unqualified declaratives. This essay considers the linguistic and normative issues side-by-side. We aim to bring some order and clarity (...) to thinking about hedging, so as to illuminate aspects of interest to both linguists and philosophers. In particular, we consider three broad questions. 1) The structural question: when one hedges, what is the speaker’s commitment weakened from? 2) The functional question: what is the best way to understand how a hedge weakens? And 3) the taxonomic question: are hedged assertions genuine assertions, another speech act, or what? (shrink)

As humans, we frequently engage in mental time travel, reliving past experiences and imagining possible future events. This study examined whether similar factors affect the subjective experience associated with remembering the past and imagining the future. Participants mentally “re-experienced” or “pre-experienced” positive and negative events that differed in their temporal distance from the present , and then rated the phenomenal characteristics associated with their representations. For both past and future, representations of positive events were associated with a greater feeling of (...) re-experiencing than representations of negative events. In addition, representations of temporally close events contained more sensorial and contextual details, and generated a stronger feeling of re-experiencing than representations of temporally distant events. It is suggested that the way we both remember our past and imagine our future is constrained by our current goals. (shrink)

Current theory-of-mind research faces the challenge of reconciling two sets of seemingly incompatible findings: Whereas children come to solve explicit verbal false belief tasks from around 4years of age, recent studies with various less explicit measures such as looking time, anticipatory looking, and spontaneous behavior suggest that even infants can succeed on some FB tasks. In response to this tension, two-systems theories propose to distinguish between an early-developing system, tracking simple forms of mental states, and a later-developing system, based on (...) fully developed concepts of belief and other propositional attitudes. One prediction of such theories is that the early-developing system has signature limits concerning aspectuality. We tested this prediction in two experiments. The first experiment showed that 2- and 3-year-olds take into account a protagonist's true or false belief about the location of an object in their active helping behavior. In contrast, toddlers' helping behavior did not differentiate between true and false belief conditions when the protagonist's belief essentially involved aspectuality. Experiment 2 replicated these findings with a more stringent method designed to rule out more parsimonious explanations. Taken together, the current findings are compatible with the possibility that early theory-of-mind reasoning is subject to signature limits as predicted by the two-systems account. (shrink)

The growth of global value chains (GVCs) and the emergence of novel forms of value chain governance pose two questions for normative business ethics. First, how should we conceptualize the relationships between members of a GVC? Second, what ethical implications follow from these relationships, both with respect to interactions between GVC members and with respect to achieving broader transnational governance goals? We address these questions by examining the emergence of transnational eco-labeling as an increasingly prominent form of GVC governance that (...) is redefining the relationship between nominally independent firms. On the first question, we argue that GVCs occupy a middle ground between intrafirm and interfirm transactions, thereby posing a challenge to theoretical frameworks that attempt to apply ethical standards based on transaction types. On the second question, we argue that this unique institutional status leads to a range of novel ethical considerations and dilemmas for GVC members. Lead firms, their suppliers, and third-party standard-setters all confront new ethical quandaries when third-party eco-labeling is introduced to a GVC. The nature of these quandaries means that, while GVCs may be well-positioned to serve as instruments of transnational governance, they are frequently not well-oriented to do so. Our analysis marks an initial attempt to map the ethical considerations that apply to members of a GVC, and in doing so, places the literature on normative business ethics and transnational governance in a closer conversation.

Recent policy developments in the area of livestock husbandry have suggested that, from the perspective of optimizing animal welfare, new animal husbandry systems should be developed that provide opportunities for livestock animals to be raised in environments where they are permitted to engage in “natural behavior.” It is not known whether consumers regard animal husbandry issues as important, and whether they differentiate between animal husbandry and other animal welfare issues. The responsibility for the development of such systems is allocated jointly (...) between farmers, regulators, different actors in the food chain, and consumers. This research focuses on understanding consumer attitudes and preferences regarding the development and introduction of such systems, to ensure that they are acceptable to consumers as well as producers, regulators, and scientists. Consumer perceptions of animal welfare and animal husbandry practices were evaluated using quantitative consumer survey, which focused on two animal husbandry issues – farmed pigs and farmed fish. Following pilot work, 1000 representative Dutch consumers were sampled about their attitudes to either pig or fish husbandry. The results indicated that consumers think about animal welfare in terms of two broad categories related to their health and living environment, but do not think about welfare issues at a more detailed level. Greater concern was expressed about the welfare of pigs compared to fish. Consumer trust in labeling also emerged as an important issue, since consumers need to trust different food chain actors with responsibility for promoting animal welfare, and are reluctant to consider the details of animal husbandry systems. As a consequence, a transparent, enforceable, and traceable monitoring system for animal welfare friendly products is likely to be important for consumers. (shrink)

Behavior oftentimes allows for many possible interpretations in terms of mental states, such as goals, beliefs, desires, and intentions. Reasoning about the relation between behavior and mental states is therefore considered to be an effortful process. We argue that people use simple strategies to deal with high cognitive demands of mental state inference. To test this hypothesis, we developed a computational cognitive model, which was able to simulate previous empirical findings: In two-player games, people apply simple strategies at first. They (...) only start revising their strategies when these do not pay off. The model could simulate these findings by recursively attributing its own problem solving skills to the other player, thus increasing the complexity of its own inferences. The model was validated by means of a comparison with findings from a developmental study in which the children demonstrated similar strategic developments. (shrink)

United Nations (UN) leaders suggest that the world is not on track to meet the Sustainable Development Goals (SDGs) by 2030. The purpose of this paper is to explore whether the SDGs provide a valuable platform to call for a basic income (BI) globally. Adopting a critical historical studies approach, the article traces the evolution of ‘development’, including the UN decades of development, the Millennium Development Goals, and the SDGs. It subsequently describes the structural adjustment and poverty reduction efforts by (...) the World Bank and International Monetary Fund, and then outlines why the SDG framework may be helpful in advancing a BI. We argue that as climate-related disasters increase, a BI will be vital in providing a modicum of security in an increasingly unstable world. Calls for BI must be anchored to a broader change agenda that recognizes the causes of poverty and income inequality, and seeks their dismantling and redress. (shrink)

Disruptions in theory of mind faculties and the ability to relate to an intersubjective reality are widely thought to be crucial to schizophrenic symptomology. This paper applies a cognitive linguistic framework to analyze spontaneous perspective-taking in two corpora of stories told by people with a schizophrenia diagnosis. We elicited natural narrative language use through life story interviews and a guided storytelling task and analyzed the linguistic construal of viewpoint in these stories. For this analysis, we developed a reliable and widely (...) applicable viewpoint model that allows for the categorization and quantification of speakers’ linguistic presentation and navigation of spatiotemporal domains. We found that our participants skillfully presented, navigated and embedded different narrative viewpoints through a variety of linguistic viewpoint devices. They presented complex viewpoints of other people in both the here-and-now of the interaction and the there-and-then of a narrative, and made use of transition markers to demarcate spatiotemporal discourse domains. We found no differences in viewpoint variables when comparing their guided stories to a control group. If problems with intersubjectivity are indeed an essential part of schizophrenia, an explanation of how this group can take on and navigate complex linguistic viewpoints in natural narrative interaction is called for.

Vaccination policy is an ethically challenging domain of public policy. It is a matter of collective importance that reaches into the most private sphere of citizens and unavoidably conflicts with individual-based ethics. Policy makers need to walk a tight rope in order to complement utilitarian public health values with individual autonomy rights, protection of privacy, non-discrimination and protection of the worst-off. Whether vaccination is voluntary or compulsory, universal or targeted, every option faces complex ethical hurdles because of the interdependence of (...) humans in infectious disease matters. In this article, we explore the following three policy questions. (i) Ethically, which policy measures should be addressed when vaccination coverage is insufficient in a population? Information campaigns, legal compulsion, or the use of financial incentives can all be effective, but also controversial policy options. (ii) Is it ethical to target vaccination programs at certain risk-groups? If such measures are necessary, we argue that policymakers will often have to decide which is more important to uphold: non-discrimination or the protection of privacy. And (iii), what is the ethical significance of adverse herd immunity effects? Some vaccination programs will improve average population health, but will at the same time increase the risk of severe morbidity and mortality for individuals in the worst-off groups of society.

The current medical approach to erectile dysfunction (ED) consists of physiological, psychological and social components. This paper proposes an additional framework for thinking about ED based on phenomenology, by focusing on the theory of sexual projection. This framework will be complementary to the current medical approach to ED. Our phenomenological analysis of ED provides philosophical depth and illuminates overlooked aspects in the study of ED. Mainly by appealing to Merleau-Ponty’s Phenomenology of Perception, we suggest considering an additional etiology of ED (...) in terms of a weakening of a function of sexual projection. We argue that sexual projection can be problematized through cognitive interferences, changes in the ‘intentional arc’, and modifications in the subject’s ‘body schema’. Our approach further highlights the importance of considering the ‘existential situation’ of patients with ED. We close by reflecting briefly on some of the implications of this phenomenological framework for diagnosis and treatment of ED. (shrink)

The King Report on Corporate Governance (1994) evoked unprecedented interest in corporate governance in South Africa. This does not mean that corporate governance was not an issue of concern before the release of this historical report. To the contrary, corporate governance in its broader sense has been at stake since the inception of the first publicly owned companies in South Africa. This article intends to give an overview of corporate governance in South Africa. It starts by making a distinction between (...) broad and narrow conceptions of corporate governance. Before applying this distinction to the practice of corporate governance in South Africa, a brief overview of the corporate landscape in South Africa is provided. Then the South African situation with regard to broad and narrow corporate governance respectively is analysed. The article ends with a discussion of the review of corporate governance that currently is in the making in South Africa. Throughout the article both the financial and ethical dimensions of corporate governance is attended to. (shrink)

In the corporate social responsibility (CSR) literature, the principle of voluntarism is predominant and implies that responsible business activities are discretionary and reach beyond the rule of law. This principle fails to explain that governments have a great interest in CSR and exercise influence on firms’ CSR activities. Therefore, we argue in favour of a contingency approach on voluntarism in CSR. To this end, we analyse the academic literature to demonstrate how governments are part of the CSR debate. We selected (...) 703 papers where the impact of governments is mentioned from five journals in our field (BEER, BEQ, BSE, BAS, JBE) in the period 1982–2011. We studied the titles and abstracts of these papers and provide an overview of: (i) the geographical orientation of the reviewed studies; (ii) the variety of government levels involved; and (iii) the various subjects where governments appear to be involved. In addition, an in‐depth reading of a subsample of 39 articles offers more details on the role of governments in the CSR literature. Hence, we offer a structured overview on the discussion of CSR and governments while stimulating a contingent understanding of the voluntarism concept in CSR. (shrink)

In this paper we examine to what extent the lengths of the links in an animated articulated figure can be changed without the viewer being aware of the change. This is investigated in terms of a framework that emphasizes the role of attention in visual perception. We conducted a set of five experiments to establish bounds for the sen-sitivity to changes in length as a function of several parameters and the amount of attention available. We found that while length changes (...) of 3% can be perceived when the relevant links are given full attention, changes of over 20% can go unnoticed when attention is not focused in this way. These results provide general guidelines for algorithms that produce or process character motion data and also bring to light some of the potential gains that stand to be achieved with attention-based algorithms.

In this article, after arguing that present approaches to improving problem-solving discussions for various reasons are not satisfactory, I turn to the pragma-dialectic approach to argumentative discourse to derive a normative framework that can serve as a point of departure to enhance the quality of problem-solving discussions. I then show how this approach can be used as analytical and evaluative instrument that can help the analyst to establish whether participants in actual practice act in a fashion that is in accord (...) with the norms posited. Two real-life problem-solving discussions provide the material for this demonstration. (shrink)
