In abstract argumentation, each argument is regarded as atomic. There is no internal structure to an argument. Also, there is no specification of what is an argument or an attack. They are assumed to be given. This abstract perspective provides many advantages for studying the nature of argumentation, but it does not cover all our needs for understanding argumentation or for building tools for supporting or undertaking argumentation. If we want a more detailed formalization of arguments than is available with (...) abstract argumentation, we can turn to structured argumentation, which is the topic of this special issue of Argument and Computation. In structured argumentation, we assume a formal language for representing knowledge and specifying how arguments and counterarguments can be constructed from that knowledge. An argument is then said to be structured in the sense that normally, the premises and claim of the argument are made explicit, and the relationship between the premises and claim is formally defined (for instance, using logical entailment). In this introduction, we provide a brief overview of the approaches covered in this special issue on structured argumentation. (shrink)

The proliferation of digital data and internet-based research technologies is transforming the research landscape, and researchers and research ethics communities are struggling to respond to the ethical issues being raised. This paper discusses the findings from a collaborative project that explored emerging ethical issues associated with the expanding use of digital data for research. The project involved consulting with researchers from a broad range of disciplinary fields. These discussions identified five key sets of issues and informed the development of guidelines (...) orientated to meet the needs of researchers and ethics committee members. We argue that establishing common approaches to assessing ethical risks of research involving digital data will promote consistency in the ethical standards for research, enable the smooth functioning of ethics committees, and sustain public confidence in research. We conclude with recommendations for the development of educational resources for ethics committees, data management guidelines and further public education. (shrink)

Research on the intersection of race and gender suggests that, for African Americans, racial inequality is more salient than gender inequality. However, theoretical perspectives on the multiplicative effects of status positions and “outsider within” models suggest that minority group membership can be a catalyst for the development of feminist attitudes. This article examines three issues central to feminism: recognition and critique of gender inequality, egalitarian gender roles, and political activism for the rights of women. The authors found that support for (...) feminist ideology was common for both African American women and men, although the level of support varied depending on the issue and by gender. Factors predicting the endorsement of feminist ideology also varied depending on the issue and by gender. The authors found partial support for the race saliency hypothesis, but there was also evidence of the multiplicative effects of status positions on African Americans' feminist attitudes. (shrink)

This article explores the meanings of manhood as articulated by Afro-American men. Conceptualization and Q-sort methods are used to examine men's construction of manhood and men's ratings of the importance of selected attributes to being a man. Manhood emerged as a multidimensional construct with four major domains and 15 distinct clusters of ideas. The cluster of attributes rated as most important to being a man paralleled the conceptualization of manhood derived from the open-ended interviews for both professional and nonprofessional men. (...) Men's ratings of attributes in the areas of ownership, manliness, spiritual and religious, and power varied by occupational status. (shrink)

The National Summit on Legal Preparedness for Obesity Prevention and Control was conceived by the Centers for Disease Control and Prevention as a strategic conference to review the current status of legal preparedness for obesity prevention and control, identify potential gaps, and develop specific action options for improving the contribution law can make to reduce the health threat posed by obesity. Working with the collaborating partners and planning committe, the host committe planned and modeled after the Summit CDC’s 2007 conference (...) on public health emergency legal preparedness that resulted in the National Action Agenda for Public Health Emergency Legal Preparedness. The summit was a working meeting that offered invited participants a structured opportunity to deliberate about the laws and legal issues that impact obesity prevention and control from a public health perspective.

The Centers for Disease Control and Prevention has focused its obesity prevention and control efforts on improving population-level health. A recent Institute of Medicine report identified systems that affect population health, to include health care delivery systems, schools, businesses and employers, communities, and governmental public health infrastructure. CDC uses the public health model to engage these systems, and this process coordinates multiple settings, sectors, and jurisdictions to develop an integrated approach to identify, prevent, and control obesity. The public health approach (...) goes beyond medical care to prioritize policy and environmental strategies that can be implemented across jurisdictional levels, in collaboration with traditional and nontraditional partners. The process ultimately produces tools, guidelines, and interventions that can be used to prevent and control obesity. In this manuscript, we provide an overview of the public health perspective on obesity, outline the public health framework for addressing obesity, and discuss the rationale for leveraging law-based efforts as a tool to accomplish the public health mission.

This paper aims at laying some foundations of a logic of argumentation in which arguments, as well as attacks and supports among arguments are all defined in a unifying formalism. In the latter, an argument is denoted as a pair displaying a reason and a conclusion but no condition is required to hold relating the reason to the conclusion. We introduce a series of inference rules relating arguments and show how the resulting system captures important features of argumentation that hitherto (...) have not been captured by existing formalisms.

Persuasion is an important and yet complex aspect of human intelligence. When undertaken through dialogue, the deployment of good arguments, and therefore counterarguments, clearly has a significant effect on the ability to be successful in persuasion. Two key dimensions for determining whether an argument is “good” in a particular dialogue are the degree to which the intended audience believes the argument and counterarguments, and the impact that the argument has on the concerns of the intended audience. In this paper, we (...) present a framework for modelling persuadees in terms of their beliefs and concerns, and for harnessing these models in optimizing the choice of move in persuasion dialogues. Our approach is based on the Monte Carlo Tree Search which allows optimization in real-time. We provide empirical results of a study with human participants that compares an automated persuasion system based on this technology with a baseline system that does not take the beliefs and concerns into account in its strategy.

Proceeding from a phenomenological perspective, the present study investigated the experiences of seven homeless women who had lived through childhood trauma and subsequent substance abuse, with specific focus on the recovery process experienced by each. Applying the analytical protocol of Giorgi to the written accounts obtained from the participants, 15 constituent themes of the recovery process were identified. In order to illuminate the participants’ experiences with minimal influence of any possible researcher bias, the researcher refrained from labelling, judging or diagnosing (...) the women’s life circumstances. Consequently, no treatment paradigm was applied to help explain, predict or judge the behaviour of the participants during the course of this research. (shrink)

A NewsFusion System is a logic-based system for merging heterogeneous structured news reports. Structured news reports are XML documents, where the textentries are restricted to individual words or simple phrases, such as names and domain-specific terminology, and numbers and units. We assume structured news reports do not require natural language processing. In previous papers, we have presented aspects of a logic-based framework for merging structured news reports based on fusion rules. Fusion rules are a form of scripting language that define (...) how structured news reports should be merged. The antecedent of a fusion rule is a call to investigate the information in the structured news reports and the background knowledge, and the consequent of a fusion rule is a formula specifying an action to be undertaken to form a merged report. It is expected that a set of fusion rules is defined for any given application. In this paper, we present a framework for aggregation predicates that can be used in fusion rules for context-dependent aggregation of structured news reports. We also present a case study that uses aggregation predicates to merge weather reports that have been obtained from a selection of websites. (shrink)

The present paper examines conventional wisdom on the subject of the justification of indigenous peoples' intellectual property rights, and offers an alternative approach. The examination is achieved by a critique of two such conventional approaches in terms of the strength of each argument employed, and in terms of the efficacy of each in the roles allotted to them. The first such argument is Stenson and Gray's application of Kymlicka's individualist theory advocating national minority autonomy. The second argument is the labour (...) entitlement theory of property acquisition, as advanced by Locke and Nozick. These theories only explain how a liberal social contract theorist would construct justifications from the outside. That this is inadequate is shown by reference to a case study involving indigenous claims against Australian law based on indigenous customary law. There, appeals are not made to abstract theory, but to tribal imperative. This observation finds sympathetic support in a reading of Hegel's philosophy of history. Hegel finds spirit in all peoples at all times. To Hegel, non-state peoples are developmentally prior to states; this means that states have developed dialectically from such peoples and cannot therefore deny them without self-contradiction. This places an onus upon a state that has subsumed an indigenous people to accommodate its laws and ways. (shrink)

The philosophers who first confronted Darwin’s revolutionary ideas actively explored their philosophical implications. Darwin himself led off, in particular, by claiming that humans’ mental abilities evolved and that they have adaptive survival value for us. From Marx to Spencer, Bergson, William James, and on to John Dewey, diverse thinkers responded, pro and con. One might expect that this ferment would lead, among other things, to new insights in the fields of perception and of mind. Surely Darwin’s ideas would become as (...) important to twentieth-century philosophy as they are to modern biology. Yet Suzanne Cunningham’s point in this book is that, historically, the influence of Darwin is lacking, particularly in analytical and phenomenological thinkers. (shrink)
