In a recent paper, a “distance” function, $\cal D$ , was defined which measures the distance between pure classical and quantum systems. In this work, we present a new definition of a “distance”, D, which measures the distance between either pure or impure classical and quantum states. We also compare the new distance formula with the previous formula, when the latter is applicable. To illustrate these distances, we have used 2 × 2 matrix examples and two-dimensional vectors for simplicity and (...) clarity. Several specific examples are calculated. (shrink)

This research engages with the problem of company–community conflict in mining. The inequitable distributions of risks, impacts, and benefits are key drivers of resource conflicts and are likely to remain at the forefront of mining-related research and advocacy. Procedural and interactional forms of justice therefore lie at the very heart of some of the real and ongoing challenges in mining, including: intractable local-level conflict; emerging global norms and performance standards; and ever-increasing expectations for the industry to translate high-level corporate social (...) responsibility policy into on-the-ground practice. This research focuses on the “process” aspects of resource conflicts through an examination of existing grievance-handling procedures at six mining operations where company–community conflict was present. In their current form, and on their own, the six mechanisms were found to be insufficient in their capacity to advance justice. The authors argue that if the overall objective of global norms is that companies construct and perform grievance handling in ways that strongly preference just practices, then “mechanisms-in-practice” must be better understood and constructively critiqued along all justice dimensions.

Simple explanations are very often inadequate and can encourage faulty inferences. We examined college students’ explanations regarding illegal immigration to determine the prevalence of single-factor explanations. The form of students’ explanations was predicted by their responses on a simple three-item forced-choice multivariable causal reasoning task in which they selected the strongest evidence against a causal claim. In a further qualitative investigation of explanations by a sample of community adults, we identified positive features among those who scored high on this multivariable (...) causal reasoning task. We consider limitations of single-factor reasoning and means of encouraging more comprehensive explanations to support claims. (shrink)

From Detroit Red to El-Hajj Malik El-Shabazz, the man best known as Malcolm X restlessly redefined himself throughout a controversial life. His transformations have appeared repeatedly in books, photographs, paintings, and films, while his murder set in motion a series of tugs-of-war among journalists, biographers, artists, and his ideological champions over the interpretation of his cultural meaning. This book marks the first systematic examination of the images generated by this iconic cultural figure--images readily found on everything from T-shirts and hip-hop (...) album covers to coffee mugs. Graeme Abernethy captures both the multiplicity and global import of a person who has been framed as both villain and hero, cast by mainstream media during his lifetime as "the most feared man in American history," and elevated at his death as a heroic emblem of African American identity. As Abernethy shows, the resulting iconography of Malcolm X has shifted as profoundly as the American racial landscape itself. Abernethy explores Malcolm's visual prominence in the eras of civil rights, Black Power, and hip-hop. He analyzes this enigmatic figure's representation across a variety of media from 1960s magazines to urban murals, tracking the evolution of Malcolm's iconography from his autobiography and its radical milieu through the appearance of Spike Lee's 1992 biopic and beyond. Its remarkable gallery of illustrations includes reproductions of iconic photographs by Richard Avedon, Eve Arnold, Gordon Parks, Henri Cartier-Bresson, and John Launois. Abernethy reveals that Malcolm X himself was keenly aware of the power of imagery to redefine identity and worked tirelessly to shape how he was represented to the public. His theoretical grasp of what he termed "the science of imagery" enabled him both to analyze the role of representation in ideological control as well as to exploit his own image in the interests of black empowerment. This provocative work marks a startling shift from the biographical focus that has dominated Malcolm X studies, providing an up-to-date--and comprehensively illustrated--account of Malcolm's cultural afterlife, and addressing his iconography in relation to images of other major African American figures, including Martin Luther King, Jr., Angela Davis, Kanye West, and Barack Obama. Analyzing the competing interpretations behind so many images, Abernethy reveals what our lasting obsession with Malcolm X says about American culture over the last five decades. (shrink)

This article draws on Foucault's concept of the exercise of power and Gramsci's concept of hegemony to examine how women used cosmetic surgery to exercise power over their bodies and lives. The analysis is rooted in two feminist perspectives on cosmetic surgery. The first argues that women who elect to have their bodies surgically altered are victims of false consciousness whose bodies are disciplined by the hegemonic male gaze. The second asserts that women who undergo elective cosmetic surgery exercise free (...) choice in controlling their bodies and lives. By examining sites wherein power is exercised by and over women, the authors argue for a synthesis of these two perspectives. They find that the women achieved greater power and control over their bodies and lives when they embodied hegemonic ideals of feminine beauty. Cosmetic surgery can be empowering for individual women while reinforcing the hegemonic ideals that oppress women as a group. (shrink)

Great effort is invested in identifying ways to change people's minds on an issue. A first priority should perhaps be enriching their thinking about the issue. With a goal of enriching their thinking, we studied the views of community adults on the DACA issue—young adults who entered the United States illegally as children. A dialogic method was employed, offering dual benefits in providing participants the opportunity to further develop their own ideas and to consider differing ideas. Yet, participants engaged in (...) dialog only vicariously by observing the talk of a pair of actors who held opposing positions on DACA. The effect on participants’ thinking was greatest in the condition in which they viewed a dialog between the two actors, rather than a comparison condition in which the actors individually expressed their positions. In control conditions, no presentation was observed. Probing questions included in all conditions encouraged a participant to examine and clarify for themselves their own position, potentially enriching it. This condition proved unsuccessful in enriching thinking; participants’ justifications for their own positions in fact became simpler and less qualified. In contrast, observing a video of a like-minded and opposing other did enrich observers’ thinking, yet to a greater degree in the dialogic than nondialogic condition. The findings thus suggest observed dialog as a promising practical approach in promoting deeper thinking. (shrink)

We argue in favour of the general proposition that the nature of reasoning is best understood within a context of its origins and development. A major dimension of what develops in the years from childhood to adulthood, we propose, is increasing meta-level monitoring and management of cognition. Two domains are examined in presenting support for these claims—multivariable causal reasoning and argumentive reasoning.

What does it take to argue well? The goal of this series of studies was to better understand the cognitive skills entailed in argument, and their course of development, isolated from the verbal and social demands that argumentive discourse also entails. Findings indicated that young adolescents are less able than adults to coordinate attention to both positions in an argument, an age-related pattern that parallels one found in discourse. Contributing to this weakness was inattention to the opposing position (in both (...) constrained and unconstrained formats), but not ability to address the opposing position when explicitly asked to do so. In addition to implementing the necessary dual focus, results point to the importance of developing epistemological understanding of the relevance of the opposing position to argument, as well as of the goals of argument more generally. The results also reflect the close parallels between dialogic and non-dialogic argument. (shrink)

Phillips & Silverstein argue that a range of cognitive disturbances in schizophrenia result from a deficit in cognitive coordination attributable to NMDA receptor dysfunction. We suggest that the viability of this hypothesis would be further supported by explicit implementation in a computational framework that can produce quantitative estimates of the behavior of both healthy individuals and individuals with schizophrenia.

We note the development of the widely employed but loosely defined construct of critical thinking from its earliest instantiations as a measure of individual ability to its current status, marked by efforts to better connect the construct to the socially-situated thinking demands of real life. Inquiry and argument are identified as key dimensions in a process-based account of critical thinking. Argument is identified as a social practice, rather than a strictly individual competency. Yet, new empirical evidence is presented documenting a (...) role for individual reasoning competencies in supporting the effectiveness of argumentive discourse. A successful curriculum is described for employing extended engagement in dialogic argumentation as a pathway to development of individual argumentive skill. (shrink)

This article investigates online representations and evaluations of EU migrants, focusing on the notion of ‘benefit tourism’ and discursive strategies used in the (de)legitimization of new welfare restrictions in the UK. Through the examination of online newspapers and corresponding public comment threads, this article adopts theoretical and methodological premises from Critical Discourse Studies (CDS), drawing upon the Discourse-Historical Approach (DHA) to provide both a politically motivated as well as reflexive account. Although new participatory structures allow for resistance to emerge, the (...) openness, scalability and anonymity of the internet also allows for the spread of discrimination through the construction of EU migrants (in particular Bulgarians and Romanians) as the ‘Other’.

Is there reason to be concerned about what has been seen as an increasing trend for discourse on complex issues to be confined to an “echo chamber” of like-minded individuals? To investigat...

Why does discourse so often seem shallow, with people arguing past one another more than with one another? Might contributing causes be individual and logical rather than only dialogical? We consider here whether there exist errors in reasoning that could be particularly damaging in their effects on argumentive discourse. In particular, we examine implications for discourse of two such errors – explanation as a replacement for evidence and neglecting the likelihood of multiple causes contributing to an outcome. In Studies 1 (...) and 2, we show these errors to be prevalent in a cross section of adults, as well as samples of community college students and young adolescents, with minimal age-related improvement. They also occur, although less frequently, among a sample of highly educated adults, and in Study 3, we examine their role in the discourse of college-educated adults. We point finally to evidence that these individual reasoning errors are potentially addressable through education. (shrink)

This article considers the question “Is There, Can There Be, such an Activity as World Humanities?” My response takes issue with the phrase “world humanity” that serves to legitimize a homogenizing process of globalization while simultaneously hiding from view the injustices and power imbalances that globalization creates. From my perspective as a Cree-Métis scholar, the world humanities are only valuable if they participate in the recuperation and protection of Indigenous stories—and by extension Indigenous languages and epistemes—that would require a reconsideration (...) of the definition and obligations of what it means to be human.

Debate rages over whether Canadian provincial and territorial governments should allow healthcare institutions to conscientiously object to providing medical assistance in dying (MAiD). This issue is likely to end up in court soon through challenges from patients, clinicians, or advocacy groups such as Dying With Dignity Canada. When it does, one key question for the courts will be whether allowing institutional conscientious objection (ICO) to MAiD respects (i.e., shows due regard for) the consciences of the objecting healthcare institutions, understood as (...) unitary entities. This question has been thoroughly explored elsewhere in the academic literature. However, another key question has been underexplored. Specifically, precedent set by the Supreme Court of Canada’s decision in Loyola High School v. Quebec (Attorney General) suggests that the courts will consider whether allowing ICO to MAiD respects the consciences of the personnel within objecting healthcare institutions. My answer to this question is no, by which I mean that allowing ICO to MAiD shows undue disregard for some consciences and undue regard for others. To justify this answer, I analyze the arguments that hold that allowing ICO in healthcare respects the consciences of the personnel within objecting healthcare institutions. My conclusion is that none of these personnel-based arguments succeed in the case of ICO to MAiD. Some fail because they are wrong about the nature of conscience and complicity. Others fail because they contradict the arguments’ proponents’ positions on conscientious objection by individual healthcare providers. Still others fail because they are internally inconsistent.

Drawing on data from interviews with 65 masculine-to-feminine transgenderists, the authors examine the coming-out experiences of transgendered individuals. Drawing on the literature that shows gender to be an inherent component of the social infrastructure that at an individual level is accomplished in interaction with others, they demonstrate that interactional challenges to gender are insufficient to challenge the system of gender. Whereas many transgenderists believe that their actions and identities are radical challenges to the binary system of gender, in fact, the (...) majority of such individuals reinforce and reify the system they hope to change.

In this paper we compare the strategies applied by two successful biological components of the ecosystem, the viruses and the human beings, to interact with the environment. Viruses have had and still exert deep and vast actions on the ecosystem especially at the genome level of most of its biotic components. We discuss on the importance of the human being as contraptions maker in particular of robots, hence of machines capable of automatically carrying out complex series of actions. Beside the (...) relevance of designing and assembling these contraptions, it is of basic importance the goal for which they are assembled and future scenarios of their possible impact on the ecosystem. We can’t procrastinate the development and implementation of a highly inspired and stringent “ethical code” for human beings and humanoid robots because it will be a crucial aspect for the wellbeing of the mankind and of the entire ecosystem.

It warrants examining how well people can come to argue under supportive conditions, not only what they do under ordinary conditions. Sustained engagement of young people in dialogic argumentation yields more than the temporary that Mercier & Sperber (M&S) identify in the target article. If such engagement were to become the norm, who can say what the argumentive potential of future generations is?
