Over the last 20 years, sex offender policies, specifically in terms of community corrections, have increased in scope. One of the most controversial and pervasive sex offender policies is that of registration. In response to the consumption of already limited resources, jurisdictions have imposed increasingly higher community supervision fees onto the offenders, requiring them to pay for their own re-entry. However, to date no research study has examined the statutory language associated with registration fees collected post release from formal community (...) sanctions. Using a statutory analysis within the United States, this research finds and quantifies the imposition of a registration fee on offenders who are legally compelled to pay these registration costs, regardless of whether they are still currently under community supervision. Results show that more than half of U.S. states (n = 28) incorporate statutory language authorizing registration fees, ranging anywhere from $5 per registration to up to $250 per year. These findings, as well as suggestions for future research and policy recommendations, are discussed. (shrink)

Mentoring relationships occur across a range of nursing contexts and are shown to have multiple, favourable personal and professional outcomes. Specifically, mentoring has been associated with the development of nurse leaders. This study describes features that are integral to initiating mentoring relationships that focus on nursing leader development. These significant features are addressed in relation to the nursing literature. Thirteen nurse leaders from eastern states of Australia were interviewed during 2005 and 2006 about their understanding and experiences of mentoring for (...) leadership. Their narratives were analysed using a hermeneutic phenomenological methodology. Mentoring relationships for nurse leadership were revealed as developing from esteemed connections between two people. Mentors were shown to unconditionally champion their mentee’s careers, and mentees were shown to possess a leadership vision for nursing. The findings of this study have implications for establishing mentoring relationships for nurse leader development. Consideration should be given to the specific focus and context of these relationships to ensure that the full potential of the mentoring process is realised. It is also important to better understand the key aspects that contribute to the phases of mentoring relationships for nurse leader development because they are shown to influence the dynamic and function of these relationships over time.

Mentorship, often viewed as a central capacity of leadership, is acknowledged as influential in growing nurse leaders. Mentoring relationships are perceived as empowering connections offering a dynamic guided experience to promote growth and development in personal and professional life. A hermeneutic phenomenological approach informed by Heidegger and Gadamer was used to explore understandings and experiences of mentorship for nurse leadership by 13 Australian nurse leaders. We found that learning and transformation associated with becoming a nurse leader mentor was experienced as (...) an enduring evolutionary process. Participants' life journeys provided experiences that developed their understandings and established their personal identity as a leader and mentor. We considered the journey motif in terms of its inextricable connection with lived time and used Heidegger's ecstasies of temporality as a lens to understand how the temporal dimensions of past, present and future influenced and shaped the development of nurse leader mentors. We found that our temporal existence influences interpretation of ourselves and the world. Individuals can benefit from multiple separate mentoring interludes, with different mentors, over a lifetime. For some nurses, becoming a leader and mentor is a lifelong transformative process that grows from diverse experience and influential role modelling rather than formal instruction. (shrink)

The way in which educators choose to engage with learners and to offer opportunities to share knowledge of both the physical world and the world of ideas is an ongoing area of international research interest but remains diffuse and difficult to systematise. This idiosyncratic quality underscores the privileged position of teachers as creative professionals. By exploring Claude Lévi-Strauss’s conception of how and for what purpose we share knowledge within society, this paper explores the relationship between perceptions of teachers’ professional role (...) and the challenges they face working within formal education systems. The artisan quality of teachers’ practice, gained through experience, association and personal commitment, makes possible a visualisation of teacher professionalism as bricolage that, when read alongside theories of teacher agency, generates an affirmative picture of how teacher professionalism may be reframed as creative and responsive rather than homogenous and mechanistic.

Although clinical ethics support services are becoming increasingly prevalent in Europe and North America, they remain an uncommon feature of the Irish healthcare system and Irish health professionals lack formal support when faced with ethically challenging cases. We have developed a variant on existing clinical ethics decision-making tools which is designed to build capacity and confidence amongst Irish practitioners and enable them to confront challenging situations in the absence of any dedicated support structure. The tool provided below follows a transparent (...) stepwise procedure which avoids an overcomplicated analysis while remaining sensitive to the complexity of the issues addressed. The novelty of the tool lies in the explicit association it makes between each step in the process and one or more responsibilities based on established norms of ethical decision-making in the public domain.

This paper argues in favour of the beneficial currency of Thomas Carlyle's ‘On Heroes, Hero-worship and the Heroic in History’ in three ways, each of which finds the basis of its critique in aspects of Foucault's theories of discursive practice, as explored in Foucault's theories of historical discourse; 1) that Carlyle's terminology connects with his discursive practice in an ambiguous manner, as his concept of worship is more akin to study than devotion, if we take the text of his lectures (...) as evidence of his perception; 2) the sources of enlightenment Carlyle offers us, based on these studies of heroic individuals, may provide an exemplar for interdisciplinary scholarship centred around biographies of notable individuals, and finally; 3) we challenge the notion that heroes such as those Carlyle offers us can be manifest in the present and argue that the depth of insight Carlyle demonstrates into his subjects is only possible by means of a lengthy temporal transition: the historicity of these narratives, and the narratives of social codification, cultural development and long-term impact witnessed and described over generations, is what makes them feasible at all.

ABSTRACT In discussions of the regulation of teaching, there are a number of issues which arise concerning how teachers understand the professional expectations upon them and the role that such standards play in supporting and maintaining the ethical dimensions of teachers’ practice. Arguably, teachers’ professional standards evolve to meet the needs of the societies in which they exist. Consequently, they provide a locus for analysis of the desires, aspirations and philosophical perspectives of the social and educational systems to which they (...) belong. Durkheim’s ideas about professional ethics provide a means of making sense of the complex and varied landscape of teacher regulation. They provide a way of seeing teacher professional standards as not constrained by neoliberal conceptions of regulation in which the fear of sanction may limit imaginative engagement with the profession. Instead, even within highly managerial systems, we begin to see professional standards as a prompt to engaged and ethical action for the greater good. In this sense, Durkheim’s work facilitates a way of seeing professional standards as having the capacity to magnify teachers’ innate potential for positive social impact regardless of the context in which they work.

In his essay on paternalism and personal identity, Wilkinson draws on Derek Parfit’s Reasons and Persons (1984) to call for a reappraisal of the role of paternalism in healthcare decision-making in situations in which patients with capacity make decisions which are likely to have harmful consequences for themselves.1 The imperative to respect autonomy, coupled with JS Mill’s insistence that the state is justified in interfering with an individual’s liberty only in situations in which she harms or threatens to harm another (...) person, leaves clinicians with little room to constrain decisions in which a patient’s choice may seriously harm her. Parfit reduces personal identity to the continuity of psychological and physical traits across the lifecourse, and suggests that, since these sets of characteristics change significantly over time, it may make more sense to view a person at different time points as different ‘selves’, rather than as the same person. Parfit’s defence of paternalism involves arguing that, given this inevitable lack of continuity, causing harm to one’s future self is analogous to harming another person and that intervening to prevent this may be justifiable in accordance with the Harm Principle.2 The issue of personal identity has received considerable attention in the philosophical literature and it remains a vexed question. Parfit’s argument, along with the thought experiments on …. (shrink)

[Multiple authors] In this paper, we propose a general architecture that is based on fast/slow solvers and a metacognitive component. We then present experimental results on the behavior of an instance of this architecture, for AI systems that make decisions about navigating in a constrained environment. We show how combining the fast and slow decision modalities allows the system to evolve over time and gradually pass from slow to fast thinking with enough experience, and that this greatly helps in decision (...) quality, resource consumption, and efficiency.

BackgroundThe use of genetic test results in risk-rated insurance is a significant concern internationally, with many countries banning or restricting the use of genetic test results in underwriting. In Australia, life insurers’ use of genetic test results is legal and self-regulated by the insurance industry (Financial Services Council (FSC)). In 2018, an Australian Parliamentary Inquiry recommended that insurers’ use of genetic test results in underwriting should be prohibited. In 2019, the FSC introduced an industry self-regulated moratorium on the use of (...) genetic test results. In the absence of government oversight, it is critical that the impact, effectiveness and appropriateness of the moratorium is monitored. Here we describe the protocol of our government-funded research project, which will serve that critical function between 2020 and 2023.MethodsA realist evaluation framework was developed for the project, using a context-mechanism-outcome (CMO) approach, to systematically assess the impact of the moratorium for a range of stakeholders. Outcomes which need to be achieved for the moratorium to accomplish its intended aims were identified, and specific data collection measures methods were developed to gather the evidence from relevant stakeholder groups (consumers, health professionals, financial industry and genetic research community) to determine if aims are achieved. Results from each arm of the study will be analysed and published in peer-reviewed journals as they become available.DiscussionThe A-GLIMMER project will provide essential monitoring of the impact and effectiveness of the self-regulated insurance moratorium. On completion of the study (3 years) a Stakeholder Report will be compiled. The Stakeholder Report will synthesise the evidence gathered in each arm of the study and use the CMO framework to evaluate the extent to which each of the outcomes have been achieved, and make evidence-based recommendations to the Australian federal government, life insurance industry and other stakeholders.

This article explores how the intersections of gendered, racialized and neoliberal dynamics reproduce social inequality and shape the violence that nurses face. Grounded in the interviews and focus groups conducted with a purposeful sample of 17 registered nurses (RNs) and registered practical nurses (RPNs) currently working in Ontario's mental health sector, our analysis underscores the need to move beyond reductionist notions of violence as simply individual physical or psychological events. While acknowledging that violence is a very real and disturbing experience (...) for individual nurses, our article casts light on the importance of a broader, power structure analysis of violence experienced by nurses in this sector, arguing that effective redress lies beyond blame shifting between clients/patients and nurses. Our analysis illustrates how assumptions about gender, race and care operate in the context of global, neoliberal forces to reinforce, intensify and create, as well as obscure, structural violence through mechanisms of individualization and normalization.

Recommendations from representatives from over twenty countries include: improving relationships across the research ecosystem; demonstrating willingness to reform and adapt systems and processes; and making the case robustly for better resourcing.

The Republic of Ireland has some of the most restrictive abortion legislation in the world which grants to the ‘unborn’ an equal right to life to that of the pregnant woman. This article outlines recent developments in the public discourse on abortion in Ireland and explains the particular cultural and religious context that informs the ethical case for access to abortion services. Our perspective rests on respect for two very familiar moral principles – autonomy and justice – which are at (...) the centre of social and democratic societies around the world. This article explains the context for the deployment of these concepts in order to support the claim that the current legislation and its operationalisation in clinical practice poses serious risks to the health, lives and well-being of pregnant women, tramples on their autonomy rights and requires of them a self-sacrifice that is unreasonable and unjust.

The aim of the present study was to provide support for the validation of the Teammate Burnout Questionnaire. Athletes from a variety of team sports completed the TBQ and the Athlete Burnout Questionnaire. Confirmatory factor analysis revealed acceptable fit indexes for the three-dimensional models of the TBQ and the ABQ. Multi-trait multi-method analysis revealed that the TBQ and ABQ showed acceptable convergent and discriminant validity. The preliminary validation of the TBQ indicates the utility of the scale to reflect athletes’ perceptions (...) of their teammates’ burnout and offers researchers the opportunity to quantitatively assess an important aspect of the social environment in the development of athlete burnout.

The aim of this paper is to provide a comprehensive exposition of the early contributions to the so-called Campbell, Baker, Hausdorff, Dynkin Theorem during the years 1890–1950. Related works by Schur, Poincaré, Pascal, Campbell, Baker, Hausdorff, and Dynkin will be investigated and compared. For a full recovery of the original sources, many mathematical details will also be furnished. In particular, we rediscover and comment on a series of five notable papers by Pascal (Lomb Ist Rend, 1901–1902), which nowadays (...) are almost forgotten. (shrink)

Much has been said about the accuracy of the famous predictions of the Russian chemist Dmitrii Ivanovich Mendeleev, but far less has been written on how he made his predictions. Here we offer an explanation on how Mendeleev used his periodic system to predict both physical and chemical properties of little-known and entirely unknown chemical elements. We argue that there seems to be compelling evidence in favour of Mendeleev genuinely relying on his periodic system in the course of issuing his (...) predictions—a point recently contested by Woody Science after the practice turn in the philosophy, history, and social studies of science, Routledge, Abington, 2014). In particular, by using the known properties of a number of near neighbours of the three entirely unknown elements, we seek to show how the very format of his table enabled it to function as a powerful tool for Mendeleev in arriving at his predicted values. We suggest that Mendeleev’s use of the periodic system in making his prediction gives an illuminative example of what Woody calls “theoretical practices” in science. (shrink)

Neodarwinian ethology, today above all represented by sociobiology, is conceived of by responsible exponents as a descriptive and explanatory theory that cannot include any normative declarations. Still other, indeed notable, authors belonging to the discipline in question, either underhand or frankly employ prescriptive or evaluative judgments, — or they claim (what is not an insight of natural science) that it is impossible to provide a rational foundation for prescriptive or evaluative judgments. (Michael Ruse and Edward O. Wilson even assert the (...) latter without relinquishing the former.) — Several functional explanations of normative validity claims advanced by Michael Ruse, Edward O. Wilson, Donald T. Campbell, Florian von Schilcher and Neil Tennant are designed to show that prescriptive or evaluative judgments cannot be justified. The reasonableness of this move is, however, dubious, because it implies strategies of raising oneself into a privileged status or of rendering the position of oneself immune from criticism by shifting it among the objects of the theory. Then Wilson's concept of 'evolutionary ethics' is thoroughly — and critically — analyzed. The suspicion that Wilson's fallacies in the transition from biological facts to moral norms are of exemplary nature is finally examined on the basis of tenets advanced by Herbert Spencer, Wolfgang Wickler, and Hans Mohr.

This paper delves into the use of machine learning-based systems in decision-making processes and its implications for moral responsibility as traditionally defined. It focuses on the emergence of responsibility gaps and examines proposed strategies to address them. The paper aims to provide an introductory and comprehensive overview of the ongoing debate surrounding moral responsibility in automated decision-making. By thoroughly examining these issues, we seek to contribute to a deeper understanding of the implications of AI integration in society.

Modern zoos strive to educate visitors about zoo animals and their wild counterparts’ conservation needs while fostering appreciation for wildlife in general. This research review examines how zoos influence those who visit them. Much of the research to-date examines zoo visitors’ behaviors and perceptions in relation to specific exhibits, animals and/or programs. In general, visitors have more positive perceptions and behaviors about zoos, their animals and conservation initiatives the more they interact with animals, naturalistic exhibits, and zoo programming/staff. Furthermore, zoo (...) visitors are receptive to conservation messaging and initiatives at zoos, and are more likely to participate in on-site conservation opportunities as opposed to after their visits. The research also suggests that repeat visitors are even more inclined to seek out conservation efforts compared to those visiting zoos for the first time. While current research suggests that repeat-visitors are more likely to engage in conservation efforts, little is known about causal factors related to such findings, and almost no research exists to-date comparing the conservation efforts of visitors vs. non-visitors. This latter comparison will likely play a greater role in future zoo visitor research, since it poses one of the most important metrics for evaluating the specific effects visiting a zoo can have on people engaging in conservation efforts in general.

Since the collapse of the Soviet Union, the United States has faced the challenge of reorienting its foreign policy to address post-Cold War conditions. In this new edition of a groundbreaking work -- one of the first to bring critical theory into dialogue with more traditional approaches to international relations -- David Campbell provides a fundamental reappraisal of American foreign policy, with a new epilogue to address current world affairs and the burgeoning focus on culture and identity in the (...) study of international relations. Extending recent debates in international relations, Campbell shows how perceptions of danger and difference work to establish the identity of the United States. He demonstrates how foreign policy, far from being an expression of a given society, constitutes state identity through the interpretation of danger posed by others. Copyright © Libri GmbH.

"How can human beings, who are liable to error, possess knowledge, since the grounds on which we believe do not rule out that we are wrong? Andrea Kern argues that we can disarm this skeptical doubt by conceiving knowledge as an act of a rational capacity. In this book, she develops a metaphysics of the mind as existing through knowledge of itself."--Provided by publisher.

In this article, I make the case for the continued relevance of Plato’s Timaeus. I begin by sketching Allan Bloom’s picture of the natural sciences today in The Closing of the American Mind, according to which the natural sciences are, objectionably, increasingly specialized and have ejected humans qua humans from their purview. I argue that Plato’s Timaeus, despite the falsity of virtually all of its scientific claims, provides a model for how we can pursue scientific questions in a comprehensive way (...) that stresses their connections to other disciplines, including the humanities, and that puts humanity qua humanity back in the picture. I then argue that being led by Plato’s philosophy to return humanity conceptually to the natural world can improve our thinking regarding climate change and other important environmental crises.

As one of the preeminent philosophers of the twentieth century, W. V. Quine made groundbreaking contributions to the philosophy of science, mathematical logic, and the philosophy of language. This collection of essays examines Quine's views, particularly his holism and naturalism, for their value to feminist theorizing today. Some contributors to this volume see Quine as severely challenging basic tenets of the logico-empiricist tradition in the philosophy of science—the analytic/synthetic distinction, verificationism, foundationalism—and accept various of his positions as potential resources for (...) feminist critique. Other contributors regard Quine as an unrepentant empiricist and, unlike feminists who seek to use or extend his arguments, they interpret his positions as far less radical and more problematic. In particular, critics and advocates of Quine's arguments that the philosophy of science should be "naturalized"—understood and pursued as an enterprise continuous with the sciences proper—disagree deeply about whether such a naturalized philosophy is "philosophy enough." Central issues at stake in these disagreements reflect current questions of special interest to feminists and also bridge the analytic and postmodern traditions. They include questions about whether and how the philosophy of science, as a form of practice, is or can be normative as well as questions concerning the implications of Quine's philosophy of language for the transparency and stability of meaning. In representing feminist philosophy centrally engaged with the analytic tradition, this volume is important not only for what it contributes to the understanding of Quine and naturalized epistemology but also for what it accomplishes in working against restrictive conceptions of the place of feminism within the discipline. Aside from the editors, the contributors are Kathryn Pyne Addelson, Louise M. Antony, Richmond Campbell, Lorraine Code, Jane Duran, Maureen Linker, Phyllis Rooney, and Paul A. Roth. (shrink)

is accounted for, among other things, in terms of particular relations between events (or states1) and places or times. Roughly speaking, an event α is said to occur in a place p (or interval t) if the spatial (temporal) extension of α is located in p (or t). Let the predicate ‘Occ’ denote such a relation. From this point of view, part of the content of the above sentences can be associated, respectively, with formulas such as.

Edmund Husserl is regarded as the founder of transcendental phenomenology, one of the major traditions to emerge in twentieth-century philosophy. In this book Andrea Staiti unearths and examines the deep theoretical links between Husserl's phenomenology and the philosophical debates of his time, showing how his thought developed in response to the conflicting demands of Neo-Kantianism and life-philosophy. Drawing on the work of thinkers including Heinrich Rickert, Wilhelm Dilthey and Georg Simmel, as well as Husserl's writings on the natural and (...) human sciences that are not available in English translation, Staiti illuminates a crucial chapter in the history of twentieth-century philosophy and enriches our understanding of Husserl's thought. His book will interest scholars and students of Husserl, phenomenology, and twentieth-century philosophy more generally. (shrink)

Andrea Falcon's work is guided by the exegetical ideal of recreating the mind of Aristotle and his distinctive conception of the theoretical enterprise. In this concise exploration of the significance of the celestial world for Aristotle's science of nature, Falcon investigates the source of discontinuity between celestial and sublunary natures and argues that the conviction that the natural world exhibits unity without uniformity is the ultimate reason for Aristotle's claim that the heavens are made of a special body, unique (...) to them. This book presents Aristotle as a totally engaged, systematic investigator whose ultimate concern was to integrate his distinct investigations into a coherent interpretation of the world we live in, all the while mindful of human limitations to what can be known. Falcon reads in Aristotle the ambition of an extraordinarily curious mind and the confidence that that ambition has been largely fulfilled. (shrink)

The conversation with Jill H. Casid and Anna Campbell is a reconceptualization of several themes to develop an aesthetic that incorporates notions of the necropolitical and redefines the concept of the Anthropocene as the Necrocene. The Necrocene implies an era marked by death, decay, and the consequences of human impact on the environment, as well as a critical reflection on the choices individuals and societies make that contribute to the transition from the Anthropocene to the Necrocene. These reflections serve (...) as cautionary tales or reflections on the unsustainable path of the Anthropocene. An important reflection in the interview is how queer and transgender people are using art and assemblages to refuse the terms of the current tensions of the culture wars. (shrink)

Though widely derided by popular psychologists and self-help writers as an emotionally toxic and destructive response, blame has many defenders among contemporary moral philosophers. Blaming wrongdoers has been thought to express deep commitment to moral values and norms, to be intimately bound up with practices of holding others responsible, and to be an important exercise of moral agency. In this paper I push against the grain of such defenses of blame just enough to articulate what seems right in the more (...) popular lines of critique. I distinguish between blame as a reactive attitude and blaming as a speech act, and argue that some disagreement over the value of blame can be explained by the fact that blaming, as a speech act, takes several distinct forms. Critiques of blame, I suggest, properly target what we might call judgmental or strongly verdictive blaming, the sort of blaming that passes judgment on the wrongdoer him- or herself, and treats him or her as deserving of the blamer’s hostile or “punishing” reactions. This kind of blaming, I argue, tends to foreclose engagement in further moral dialogue with wrongdoers, an effect that is particularly destructive in therapeutic contexts. In such contexts, it is often more appropriate—and more constructive—to hold others answerable without blaming them in the strongly verdictive sense. I argue, moreover, that strongly verdictive blame may be similarly destructive outside of straightforwardly therapeutic contexts, and I challenge the idea that there is in any case a sharp or clear dividing line between therapeutic and non-therapeutic responses to wrongdoers. Holding answerable in a non-judgmental mode is a response that may have a therapeutic dimension, but it nonetheless engages a wrongdoer as a moral peer and partner in moral dialogue. This account of non-judgmental answerability, I suggest, captures much of what moral philosophers have taken to be valuable about blame, while accommodating the insights of those who criticize its more toxic forms.

According to a view called 'nihilism', sentences containing vague expressions cannot strictly speaking be true or false, because they lack definite truth conditions. While most theorists of vagueness tend to regard nihilism as a hopeless view, a few isolated attempts have been made to defend it. This paper aims to develop such attempts in a new direction by showing how nihilism, once properly spelled out, can meet three crucial explanatory challenges that respectively concern truth, assertibility, and communication.
