Social bots – partially or fully automated accounts on social media platforms – have not only been widely discussed, but have also entered political, media and research agendas. However, bot detection is not an exact science. Quantitative estimates of bot prevalence vary considerably and comparative research is rare. We show that findings on the prevalence and activity of bots on Twitter depend strongly on the methods used to identify automated accounts. We search for bots in political discourses on Twitter, using (...) three different bot detection methods: Botometer, Tweetbotornot and “heavy automation”. We drew a sample of 122,884 unique user Twitter accounts that had produced 263,821 tweets contributing to five political discourses in five Western democracies. While all three bot detection methods classified accounts as bots in all our cases, the comparison shows that the three approaches produce very different results. We discuss why neither manual validation nor triangulation resolves the basic problems, and conclude that social scientists studying the influence of social bots on communication and discourse dynamics should be careful with easy-to-use methods, and consider interdisciplinary research.

Gender dysphoria (GD) is marked by an incongruence between a person’s biological sex at birth, and their felt gender (or gender identity). There is continuing debate regarding the benefits and drawbacks of physiological treatment of GD in children, a pathway, beginning with endocrine treatment to suppress puberty. Currently, the main alternative to physiological treatment consists of the so-called “wait-and-see” approach, which often includes counseling or other psychotherapeutic treatment. In this paper, we argue in favor of a “third pathway” for the (...) diagnosis and treatment of GD in youths. To make our case, we draw on a recent development in bioethics: the phenomenological approach. Scholars such as Slatman and Svenaeus have argued that the extent to which the body can (or should be) manipulated or reconstructed through medical intervention is not only determined by consideration of ethical frameworks and social and legal norms. Rather, we must also take account of patients’ personal experience of their body, the personal and social values associated with it, and their understanding of its situation in their life: their narrative identities. We apply this phenomenological approach to medicine and nursing to the diagnosis and treatment of GD in youth. In particular, we discuss Zahavi and Martiny’s conception of the phenomenological interview, in order to show that narrative techniques can assist in the process of gender identification and in the treatment of youth presenting with GD. We focus on two case studies that highlight the relevance of a narrative-based interview in relations between patients, HCPs, and family, to expose the influence of social ideologies on how young people presenting with GD experience their bodies and gender.

The Vestal Virgins are one of the most famous elements of Roman religion, yet despite their perennial appeal and the importance of some smaller scale studies of the priesthood, the priestesses have not received a monograph-length study since F. Giuzzi, Aspetti giuridici del sacerdozio romano. II sacerdozio di Vesta (Naples, 1968). Now we have books by R.L. Wildfang and M.C. Martini that could not be more different. The former offers a thorough survey of what the sources can tell us (...) about the priesthood in the period from the end of the Second Carthaginian War to the first century C.E. The latter is an analysis of early Roman historiography and the role the Vestals, in particular their periodic unchastity, played in the creation of the traditional account of the development of Rome. W's book puts forward two main arguments: (1) the Vestals were charged with the ritual purification of the city and with the storage and preparation of ritual materials, and (2) many aspects of the priesthood that have long puzzled scholars are tied to the Vestals' status as Roman citizens, but citizens who existed outside the traditional family structure. The book will be accessible to those new to the topic, but the notes will repay specialists. Ancient sources are quoted in translation, with original texts provided in an appendix. A second appendix provides a list of known Vestals. This slender volume could have been even thinner if the frequent repetitions were cut down. W's work might have been better as a hefty article, so little is there to know about the Vestals. The Classical Review vol. 58 no. 1 C The Classical Association 2008; all rights reserved This content downloaded from 204.235.148.90 on Sat, 26 Jul 2014 11:47:09 AM All use subject to JSTOR Terms and Conditions THE CLASSICAL REVIEW 213 In the Introduction, W makes a welcome distinction among types of rituals often lumped together in discussions of 'fertility' rituals, with which the Vestals are often associated (p. 4). W reserves 'fertility' to describe only those rites that deal with the reproduction of people, livestock and the growth of crops. Harvest rituals are linked to the harvesting of crops, while another set of rites, 'storage rites', are tied to the preservation of the harvest. The final group, purification rituals, aim at the cleansing of an individual, place or object of 'all forms of pollution that would render it or them unfit to come into contact with the religious sphere'. The book is arranged thematically. The first two chapters lay out all we can know about the priestesses' ritual obligations performed in the seclusion of the temple and out amongst the people. While a reader may not find W's interpretation of each of the Vestals' actions equally persuasive, the overall argument that the priestesses' activities were, by and large, purificatory is convincing. Two of the more interesting aspects of W.'s discussion are her considerations of Vesta's fire and of the water required for some of her rituals (pp. 8-11). Fire was seen by the Romans as both a fertile and a sterile force, and scholars have emphasised one or the other, or the contrast between them, in their interpretation of the Vestals. W points out that fertile fire is always described in masculine terms and is associated with Vulcan. Vesta's fire, however, is always associated with sterility and purity, and so should be understood as having a purificatory significance. W points out that Vesta's fire was used only in the manufacture of ritually necessary items: roasting spelt for mola salsa, baking brine for muries and burning ashes from the fetal cow from the Fordicidia and the tail of the October horse, both of which were used at the Parilia. For other rituals, the Vestals were required to use water, the purificatory substance par excellence, drawn only from the spring of Juturna and carried only in vessels that could not be set down. These restrictions ensured that the water was always fresh, running water that never touched profane earth. Chapters 3-5 trace out the unique position the Vestals occupied in Roman society, arguing that they existed outside the standard Roman familial and other social structures, yet remained fully part of the Roman state. W suggests that the initiation rite of captio removed the new priestess not only from her family but, more importantly, from her family cult, thus avoiding any potential contamination of familial and public cult. Virginity was required for multiple reasons, the most significant being that such a status allowed the priestess to remain a full member of the Roman state, but prevented her from being a member of a traditional family structure. Throughout the book, W makes much of the idea of Vestals as represen tatives of Roman citizen women without ever really dealing with the question to what extent any Roman woman, priestess or not, was a ciuis. Though W is probably correct, it is not entirely certain to what extent women were citizens in the Republic, and at least a reference to some key ancient sources and to recent scholarship on this question should be made (e.g. L. Peppe, Posizione giuridica e ruolo sociale della donna romana in eta repubblicana [Milan, 1984]). The sixth chapter, 'The Vestals in the Romans' History', looks at the appearance of Vestals in the early history of Rome, refining the common assumption that accusations of, and convictions for, incestum arose only in periods of great stress and danger. W adds that a priestess's involvement, or her family's involvement, in one of the groups taking part in the conflict or struggle of the moment also played a role. This chapter traces changes over the course of 300 years in the attitudes of the priestesses and the Romans more generally toward the priesthood, its role in society This content downloaded from 204.235.148.90 on Sat, 26 Jul 2014 11:47:09 AM All use subject to JSTOR Terms and Conditions 214 THE CLASSICAL REVIEW and its requirement of 30 years of chastity. The argument hangs on even less evidence than other sections of the work. In contrast to their central place in W's book, the Vestals play only a small (though crucial, in her interpretation) role in M.'s work. The basic argument of the book is that episodes of Vestal incestum are linked in the historiographic tradition to key moments in the development of the Roman state: the separation of augurium from regnum, the development of a mixed patrician-plebeian aristocracy, the creation of a monetary system and the expansion of the colonial system outside Italy. The history of Rome can be seen as alternating phases of stasis and transformation; instances of Vestal incestum mark the transitions (p. 95). The work falls into two parts that are not well integrated. The first is a useful discussion of the historiography of the Roman Republic, taking in turn each element of the story of the founding of Rome from the arrival of Aeneas to the death of Remus. M. traces how early Roman writers, especially Fabius Pictor, reshaped the tradition already present in some Greek authors, distancing Rome from the Greek world and adding an Italic element to the tale. This detailed analysis is well worth consulting and will be of interest to those working on many aspects of cultural life in the Republic. The second, larger, section of the book comprises a series of studies of the Vestals known to have been convicted of incestum during the Republic. After dealing with issues of dating and sources, M. links each case of incestum to a major event in Roman history. Not all the events are equally important for the creation of the Rome of the middle and late Republic. One wonders why M. chose to tie the conviction of Minucia, somewhere between 339 and 332, to the admission of plebeians to the praetorship in 337 rather than to the conclusion of the Latin War in 338. Some explanation is warranted. The connection M. draws is often very vague, as in the case of Sextilia (pp. 144-54), convicted and interred alive in either 275 or 274. M. sees this as marking the end of any meaningful distinction between patricians and plebeians, following as it does the first time a plebeian censor completed a lustrum. The gap of five or six years between Sextilia's conviction and Cn. Domitius Calvinus Maximus' censorship in 280 passes unremarked. Similarly, in discussing the three Vestals accused of incestum in 114-113 (pp. 188-210), M. steps away from the commonly accepted interpretation of the event as part of the continuing struggle between Gracchan and senatorial forces, arguing instead that it is tied to the establishment in 118 of the colony of Narbo Martius, Rome's first colony in Gaul. Here, as elsewhere, there is no evidence that any ancient author linked the founding of the colony and Vestal unchastity; the temporal gap makes an association even more unlikely. Ultimately, it is not possible to accept M.'s argument that Vestal incestum punctuated key stages in the development of the 'cosmo Romano' in the way she imagines. Even so, M.'s effort to reintegrate the Vestals into the larger narrative of Rome's history is thought-provoking, and it is to be hoped that it will spark further work in the same vein. The field is perhaps in a better position to undertake work on this scale now that we have W's careful and comprehensive collection and interpre tation of what there is to know about the Vestals.

Reason and Value collects 15 new papers by leading contemporary philosophers on themes from the work of Joseph Raz. Raz has made major contributions in a wide range of areas, including jurisprudence, political philosophy, and the theory of practical reason; but all of his work displays a deep engagement with central themes in moral philosophy. The subtlety and power of Raz's reflections on ethical topics make his writings a fertile source for anyone working in this area. Especially significant are his (...) explorations of the connections between practical reason and the theory of value, which constitute a sustained and penetrating treatment of a set of issues at the very center of moral philosophy as it is practiced today. The contributors to the volume acknowledge the importance of Raz's contributions by engaging critically with his positions and offering independent perspectives on the topics that he has addressed. The volume aims both to honour Raz's accomplishments in the area of ethical theorizing, and to contribute to an enhanced appreciation of the significance of his work for the subject. (shrink)

How do we access the authentic self in order to live fulfilling, meaningful lives? In straightforward terms, The Heart of the Matter: Gifts in Strange Wrapping Paper explains a simple but extraordinarily powerful technique called the See, Feel, Hear Challenge that enables people to easily gain entry into the storehouse of their subconscious core beliefs. In the process, it cracks the coded messages that those beliefs release in the form of disease, suffering, addictions, unhappy relationships, and victimized circumstances. Based in (...) the latest findings in neuroscience and neurocardiology, this book guides readers to an uncomplicated understanding of the astounding power of our emotions and how life automatically delivers experiences that trigger negative reactions that subconsciously impact us. These emotions form the foundation of core beliefs that create unhealthy attitudes and dis-ease patterns that keep us from experiencing the authentic, satisfying lives we desire. Using clear examples and true stories from clients, Dr. Weissman’s latest work demonstrates how we can release these stored emotions and their wisdom via the See, Feel, Hear Challenge. It then explains how to use this simple method to evoke feelings that positively impact the quantum field, remolding our bodies, minds, and everyday lives into purposeful expressions of inner joy and radiant well-being. Whether you’re dealing with addictions, dysfunctional relationships, or illness, or are focused on becoming an Olympic champion, The Heart of the Matter gives you a potent tool for positive change and transformation that you can use for the rest of your life.

Despite the growing interest and supporting evidence for person-centered care, there is still a fundamental disagreement about what makes healthcare person-centered. In this article, we define PCC as operating with three fundamental conditions: personal, participatory and holistic. To further understand these concepts, we develop a framework based on the theory of affordances, which we apply to the healthcare case of rehabilitation and a concrete experiment on social interactions between persons with cerebral palsy and physio- and occupational therapists. Based on the (...) application of the theory, we argue that in order for healthcare to be considered as PCC, professionals need to adopt a personalistic attitude in their care, defined in terms of mutual affordances: how the professional and the person of care acknowledges each other as a person in an interaction. In opposition, we define the functionalistic attitude in terms of object affordances, those related to a concrete goal. We show that PCC requires a balance of personalistic and functionalistic attitudes, since this contributes to a participatory and holistic conception of, and interaction with, the person of care.

Research in phenomenology has benefitted from using exceptional cases from pathology and expertise. But exactly how are we to generate and apply knowledge from such cases to the phenomenological domain? As researchers of cerebral palsy and musical absorption, we together answer the how question by pointing to the resource of the qualitative interview. Using the qualitative interview is a direct response to Varela’s call for better pragmatics in the methodology of phenomenology and cognitive science and Gallagher’s suggestion for phenomenology to (...) develop its methodology and outsource its tasks. We agree with their proposals, but want to develop them further by discussing and proposing a general framework that can integrate research paradigms of the well-established disciplines of phenomenological philosophy and qualitative science. We give this the working title, a “phenomenological interview”. First we describe the what of the interview, that is the nature of the interview in which one encounters another subject and generates knowledge of a given experience together with this other subject. In the second part, we qualify why it is worthwhile making the time-consuming effort to engage in a phenomenological interview. In the third and fourth parts, we in general terms discuss how to conduct the interview and the subsequent phenomenological analysis, by discussing the pragmatics of Vermersch’s and Petitmengin’s “Explicitation Interview”.

Elliot R. Wolfson intervenes in the debate over Martin Heidegger and Nazism from a unique perspective, as a scholar of Jewish mysticism and philosophy who has been profoundly influenced by Heidegger's work. He reveals crucial aspects of Heidegger's thinking that betray an affinity with dimensions of Jewish thought.

The paper defends the position that phenomenological interviews can provide a rich source of knowledge and that they are in no principled way less reliable or less valid than quantitative or experimental methods in general. It responds to several skeptic objections such as those raised against introspection, those targeting the unreliability of episodic memory, and those claiming that interviews cannot address the psychological, cognitive and biological correlates of experience. It argues that the skeptic must either heed the methodological and epistemological (...) justification of the phenomenological interview provided, or embrace a more fundamental skepticism, a “deep mistrust”, in which scientific discourse can have no recourse to conscious processes as explananda, with ensuing dire consequences for our conception of science.

Two quantum Macro-states and their Macroscopic Quantum Superpositions (MQS) localized in two far apart, space-like separated sites can be non-locally correlated by any entangled couple of single-particles having interacted in the past. This novel “Macro-Macro” paradigm is investigated on the basis of a recent study on an entangled Micro-Macro system involving N≈105 particles. Crucial experimental issues as the violation of Bell’s inequalities by the Macro-Macro system are considered.

In this paper we analyze the resilience to decoherence of the Macroscopic Quantum Superpositions (MQS) generated by optimal phase-covariant quantum cloning according to two coherence criteria, both based on the concept of Bures distance in Hilbert spaces. We show that all MQS generated by this system are characterized by a high resilience to decoherence processes. This analysis is supported by the results of recent MQS experiments of N=3.5×104 particles.

One is the beloved author of The Name of the Rose, a celebrated scholar, philosopher, and self-declared secularist; the other is a preeminent clergyman and a respected expert on the New Testament. In this intellectually stimulating dialogue, often adversarial but always amicable, these two great men, who stand on opposite sides of the church door, discuss some of the most controversial issues of our day, including the apocalypse, abortion, women in the clergy, and ethics. As we voyage onward into the (...) new millennium, they frame a debate about matters that have already begun to rage, always aware of the gulf between belief and nonbelief that separates them, constantly probing and challenging, but also respectful of the other’s viewpoint. For believers and nonbelievers alike, the result is both edifying and illuminating. “Their correspondence,” writes Professor Harvey Cox in his introduction, “lifts the possibility of intelligent conversation on religion to a new level.”.

This paper focuses on the question of how to resolve disagreement and uses the Lehrer-Wagner model as a formal tool for investigating consensual decision-making. The main result consists in a general definition of when agents treat each other as epistemic peers (Kelly 2005; Elga 2007), and a theorem vindicating the “equal weight view” to resolve disagreement among epistemic peers. We apply our findings to an analysis of the impact of social network structures on group deliberation processes, and we demonstrate their (...) stability with the help of numerical simulations.

Research integrity (RI) is defined as adherence to ethical principles, deontological duties, and professional standards necessary for responsible conduct of scientific research. Early training on RI, especially for early-career researchers, could be useful to help develop good standards of conduct and prevent research misconduct (RM).The aim of this study is to assess the effectiveness of a training course on RI, by mapping the attitudes of early-career researchers on this topic through a questionnaire built upon the revised version of the Scientific (...) Misconduct Questionnaire and administered to all participants at the beginning and at the end of the course.Results show that after the course, participants reporting a high understanding of the rules and procedures related to RM significantly increased (pre-course: 38.5%, post-course: 61.5%), together with the percentage of those reporting a lack of awareness on the extent of misconduct (pre-course: 46.2%, post-course: 69.2%), and of those who believe that the lack of research ethics consultation services strongly affects RM (pre-course: 15.4%, post-course: 61.5%). Early-career researchers agree on the importance to share with peers and superiors any ethical concern that may arise in research, and to create a work environment that fosters RI awareness.As a whole, results suggest the effectiveness of the course. Institutions should introduce RI training for early-career researchers, together with research methodology, integrity and ethics consultation services to support them. Senior scientists should promote RI into their research practices, and should stimulate engagement in peer-to-peer dialogue to develop good practices based on RI principles. (shrink)

This book focuses upon the perennial question of the existence and nature of an obligation to obey the law. Leading writers have, at one time or another, emphasized considerations such as gratitude, 'divine ordering, ' prudence, contract, autonomy, and utility in seeking to justify, or to deny any justification for, some sort of obligation to obey the positive law. The book provides relevant selections from a sampling of the historical approaches to legal obligation taken by writers such as Plato, Augustine, (...) Aquinas, Hobbes, Locke, Hume, Rousseau, Thoreau, Bentham, Marx and Engels, and Martin Luther King, Jr. These classical discussions are augmented by critical questions and commentary, by independent discussions of the question of legal obligation by a wide range of contemporary writers, and by relevant judicial cases discussing matters such as conscientious objection and civil disobedience.

In this paper we argue that there is a kind of moral disagreement that survives the Rawlsian veil of ignorance. While a veil of ignorance eliminates sources of disagreement stemming from self-interest, it does not do anything to eliminate deeper sources of disagreement. These disagreements not only persist, but transform their structure once behind the veil of ignorance. We consider formal frameworks for exploring these differences in structure between interested and disinterested disagreement, and argue that consensus models offer us a (...) solution concept for disagreements behind the veil of ignorance.

A rigorous ab initio derivation of the (square of) Dirac’s equation for a particle with spin is presented. The Lagrangian of the classical relativistic spherical top is modified so to render it invariant with respect conformal changes of the metric of the top configuration space. The conformal invariance is achieved by replacing the particle mass in the Lagrangian with the conformal Weyl scalar curvature. The Hamilton-Jacobi equation for the particle is found to be linearized, exactly and in closed form, by (...) an ansatz solution that can be straightforwardly interpreted as the “quantum wave function” of the 4-spinor solution of Dirac’s equation. All quantum features arise from the subtle interplay between the conformal curvature acting on the particle as a potential and the particle motion which affects the geometric “pre-potential” associated to the conformal curvature itself. The theory, carried out here by assuming a Minkowski metric, can be easily extended to arbitrary space-time Riemann metric, e.g. the one adopted in the context of General Relativity. This novel theoretical scenario appears to be of general application and is expected to open a promising perspective in the modern endeavor aimed at the unification of the natural forces with gravitation.

The concept of yinyang lies at the heart of Chinese thought and culture. The relationship between these two opposing, yet mutually dependent, forces is symbolized in the familiar black and white symbol that has become an icon in popular culture across the world. The real significance of yinyang is, however, more complex and subtle. This brilliant and comprehensive analysis by one of the leading authorities in the field captures the richness and multiplicity of the meanings and applications of yinyang, including (...) its visual presentations. Through a vast range of historical and textual sources, the book examines the scope and role of yinyang, the philosophical significance of its various layers of meanings and its relation to numerous schools and traditions within Chinese philosophy. By putting yinyang on a secure and clear philosophical footing, the book roots the concept in the original Chinese idiom, distancing it from Western assumptions, frameworks and terms, yet also seeking to connect its analysis to shared cross-cultural philosophical concerns.

Information can be public among a group. Whether or not information is public matters, for example, for accounts of interdependent rational choice, of communication, and of joint intention. A standard analysis of public information identifies it with (some variant of) common belief. The latter notion is stipulatively defined as an infinite conjunction: for p to be commonly believed is for it to believed by all members of a group, for all members to believe that all members believe it, and so (...) forth. This analysis is often presupposed without much argument in philosophy. Theoretical entrenchment or intuitions about cases might give some traction on the question, but give little insight about why the identification holds, if it does. The strategy of this paper is to characterize a practical-normative role for information being public, and show that the only things that play that role are (variants of) common belief as stipulatively characterized. In more detail: a functional role for “taking a proposition for granted” in non-isolated decision making is characterized. I then present some minimal conditions under which such an attitude is correctly held. The key assumption links this attitude to beliefs about what is public. From minimal a priori principles, we can argue that a proposition being public among a group entails common commitment to believe among that group. Later sections explore partial converses to this result, the factivity of publicity and publicity from the perspective of outsiders to the group, and objections to the aprioricity of the result deriving from a posteriori existential presuppositions.

Despite a long history of researchers who combine phenomenology with qualitative or quantitative methods, there are only few examples of working with a phenomenological mixed method—a method where phenomenology informs both qualitative and quantitative data generation, analysis, and interpretation. Researchers have argued that in working with a phenomenological mixed method, there should be mutual constraint and enlightenment between the qualitative and quantitative methods for studying consciousness. In this article, we discuss what a framework for phenomenological mixed methods could look like (...) and we aim to provide guidance of how to work within such framework. We are inspired by resources coming from research in mixed methods and existing examples of phenomenological mixed-method research. We also present three cases of phenomenological mixed methods where we study complex social phenomena and discuss the process of how we conducted the studies. From both the research inspiration and our own studies, we depict the landscape of possibilities available for those interested in mixing phenomenology with qualitative and quantitative methods, as well as the challenges and common pitfalls that researchers face. To navigate in this landscape, we develop a three-fold structure, focusing on the phenomenological frame, the phenomenologically informed generation of qualitative and quantitative data, and the phenomenologically informed analysis and interpretation of data.
