Both unipolar and bipolar depression have been linked with impairments in executive functioning. In particular, mood symptom severity is associated with differences in common EF, a latent measure of general EF abilities. The relationship between mood disorders and EF is particularly salient in adolescence and young adulthood when the ongoing development of EF intersects with a higher risk of mood disorder onset. However, it remains unclear if common EF impairments have associations with specific symptom dimensions of mood pathology such as (...) blunted positive affect, mood instability, or physiological arousal, or if differences in common EF more broadly relate to what is shared across various symptom domains, such as general negative affect or distress. To address this question, bifactor models can be applied to simultaneously examine the shared and unique contributions of particular mood symptom dimensions. However, no studies to our knowledge have examined bifactor models of mood symptoms in relation to measures of common EF. This study examined associations between common EF and general vs. specific symptom dimensions using structural equation modeling in adolescents and young adults with varying severity of mood symptoms. A General Depression factor capturing shared variance across symptoms statistically predicted lower Common EF. Additionally, a factor specific to physiological arousal was associated with lower Common EF. Anhedonia-specific and Mania-specific factors were not significantly related to Common EF. Altogether, these results indicate that deficits in common EF are driven by, or reflect, general features of mood pathology that are shared across symptom dimensions but are also specifically associated with physiological arousal.

Research involving transgender and gender diverse people (TGD) increased in the last years, mostly concerning healthcare associated to this population. Few studies dedicated their analysis to the impact of parental support on transgender people, even though this is an important aspect in creating a safe environment on which these individuals can build their identity. In addition, the link between family support, TGD identity and homelessness is not completely established. Thus, due to the specificities of the family context of TGD individuals, (...) the aim of this study is to investigate the association between family support and TGD in different moments of the process of gender affirmation. In addition, this study also aims to explore the relationship between a lack of social support and low self-esteem, home abandonment, and dwelling in the street. The survey was designed based on the TransPULSE project and was made available in electronic format. The sample was constituted of 423 TGD residents in two Brazilian states. A Structural Equation Model analysis suggested that the impact of gender affirmation status on homelessness was mediated by parental support, through self-esteem, and the need to move from home. The association between the status of the gender affirmation procedures, family support and self-esteem was significant and indicated that the further TGD individuals advanced in gender affirmation, the more self-esteem and family support they would have. The association between family support and self-esteem indicated that family support was associated with higher self-esteem. Low family support was associated with the willingness to move from home due to one’s TGD status and there was also a significant correlation between low self-esteem and the willingness to move from home due to one’s TGD status. Finally, homelessness was associated with the willingness to move with a large effect size. Limitations include the sample that was constituted by individuals with Internet access and who had more contact with TGD communities. The findings indicate directions for interventions involving TGD people and their families, considering the parental relationship as a critical variable to improve TGD quality of life in the process of gender affirmation.

In this article, I argue that revenge fantasies such as those found in the Oracles Against the Nations in Jeremiah 45-51 underscore the necessity for responsible Bible reading practices. I argue that to protect us from our own worst selves, the very human tendency to resort to revenge that inevitably leads to violence, one needs to read these biblical texts in terms of contemporary hermeneutical approaches that may play some role to bring an end to violence. A first such approach (...) that serves as an important tool to help us understand these revenge fantasies as found in the OAN is the relatively new field of inquiry of trauma hermeneutics that is particularly helpful in order to mitigate the violent aspects of these revenge fantasies. Moreover, I propose that recent approaches such as feminist and postcolonial biblical interpretation are also vital for nurturing ethical, just communities that actively pursue justice. (shrink)

This paper challenges T. S. Gendler's notion of aliefs, a novel kind of mental state which she introduces to explain a wide variety of belief-discordant behaviors. In particular, I argue that many of the cases which she uses to motivate such a mental state can be fully explained by accounts that make use only of commonplace attitudes such as beliefs and desires.

It has recently been argued that hope is polysemous in that it sometimes refers to hoping and other times to being hopeful. That it has these two distinct senses is reflected in the observation that a person can hope for an outcome without being hopeful that it will occur. Below, I offer a new argument for this distinction. My strategy is to show that accepting this distinction yields a rich account of two distinct ways in which hope can be lost, (...) ways that map onto the two senses of hope: A person can lose hope either by ceasing to hope for an outcome (hopelessness) or by ceasing to be hopeful that it will obtain (despair). Thinking about these negative attitudes in these two ways, I contend, is explanatorily rich and fruitfully reveals how they differ in phenomenology, behavioral differences, and the ways in which a person can escape them.

Physicians have an ethical responsibility to their patients to offer the best available medical care. This responsibility conflicts with their role as gatekeepers of the limited health care resources available for all patients collectively. It is ethically untenable to expect doctors to face this trade-off during each patient encounter; the physician cannot be expected to compromise the wellbeing of the patient in the office in favour of anonymous patients elsewhere. Hence, as in other domains of public policy where individual and (...) collective interests conflict, some form of collective solution is required. Collective solutions may take the form of placing explicit resource constraints on resources available to physicians, or clinical practice guidelines that recognise cost-effective care as acceptable. Such solutions will be politically and ethically sustainable only if patients as citizens of the larger population accept the need for rationing of limited resources in health care. (shrink)

The answer to philosophical questions will often depend on the position one takes regarding the fact-value problem. It is, therefore, not surprising that, in the tradition of western philosophy, the past 200 years or so record an animated discussion of it. In the present collection the debate is continued by representatives of various "schools" in contemporary western thought. A number of philosophers from non-western cultures, too, enter into it. The contributions do not all reflect on the same theme, nor do (...) they use the same approach. Essays written by philosophers sympathetic to the analytical tradition are followed by reflections on the part of those inspired by phe nomenology. A third group of contributions is by non-western thinkers, who are more likely to approach the problem in terms of culture. Their engage ment with the issue clearly shows, among other things, that it is almost exclusively in the western tradition that the fact-value distinction is often understood as an outright dichotomy. The occasion for the publication of this collection is Dr. Cornelis Anthonie van Peursen's retirement as Professor of Philosophy. This year he leaves the Free University, Amsterdam; until 1982 he was professor at the University of Leyden as well. In the Netherlands and beyond he has become known for his concern with constructive comparison of diverging philosophical trends and the cross-cultural fertilization of thought. Characteristic of his career are his efforts to render the results of academic philosophizing understand able to a broader audience. (shrink)

Today's modern car is an assemblage of mechanical and digital components, of metal panels that comprise its structure and silicon chips that run its functions. Communication and information studies scholars have interrogated the problematic aspects of the programs that run those functions, revealing serious issues surrounding privacy and security, worker surveillance, and racial, gendered, and class-based bias. This article contributes to that work by taking a step back and asking about the issues inherent not in the software running on these (...) chips, but on the microchips themselves. Using the lens of “chipification”—the process by which a device is rendered capable of reading and processing data through the embedding of microchips—this article explores how the integration of microchips also involves processes that are often borne from, replicate, or create troubling power dynamics of their own. It takes light-duty passenger vehicles as a case study into how chipification is radically reshaping such processes as resource allocation, labor flows, and cultural practices around car manufacture, use, repair, and modification. By naming the process of chipification, this article allows researchers to identify and analyze the ways that integrating data processing capabilities into everyday devices is not a frictionless practice, but rather one that implicates a variety of power dynamics within these massive industries.

The requirement of gauge invariance for the Schwinger-DeWitt equations, interpreted as a manifestly covariant quantum theory for the evolution of a system in spacetime, implies the existence of a five-dimensional pre-Maxwell field on the manifold of spacetime and “proper time” τ. The Maxwell theory is contained in this theory; integration of the field equations over τ restores the Maxwell equations with the usual interpretation of the sources. Following Schwinger's techniques, we study the Green's functions for the five-dimensional hyperbolic field equations (...) for both signatures ± [corresponding to O(4, 1) or O(3, 2) symmetry of the field equations] of the proper time derivative. The classification of the Green's functions follows that of the four-dimensional theory for “massive” fields, for which the “mass” squared may be positive or negative, respectively. The Green's functions for the five-dimensional field are then given by the Fourier transform over the “mass” parameter. We derive the Green's functions corresponding to the principal part ΔP and the homogeneous function Δ 1 ; all of the Green's functions can be expressed in terms of these, as for the usual field equations with definite mass. In the O(3, 2) case, the principal part function has support for x2⩾τ2, corresponding to spacelike propagation, as well as along the light cone x2=0 (for τ=0). There can be no transmission ofinformation in spacelike directions, with this propagator, since the Maxwell field, obtained by integration over τ, does not contain this component of the support. Measurements are characterized by such an integration. The spacelike field therefore can dynamically establish spacelike correlations. (shrink)

This volume sheds light on still unexplored issues and raises new questions in the main areas addressed by the philosophy of science. Bringing together selected papers from three main events, the book presents the most advanced scientific results in the field and suggests innovative lines for further investigation. It explores how discussions on several notions of the philosophy of science can help different scientific disciplines in learning from each other. Finally, it focuses on the relationship between Cambridge and Vienna in (...) twentieth century philosophy of science. The areas examined in the book are: formal methods, the philosophy of the natural and life sciences, the cultural and social sciences, the physical sciences, and the history of the philosophy of science.

A new human life comes into being not when there is mere cellular life in a human embryo, but when the newly developing body organs and systems begin to function as a whole, the author argues. This is symmetrical with the dealth of an existing human life, which occurs when its organs and systems have permanently ceased to function as a whole. Thus a new human life cannot begin until the development of a functioning brain which has begun to co-ordinate (...) and organise the activities of the body as a whole. (shrink)

Despite the many successes of the relativistic quantum theory developed by Horwitz et al., certain difficulties persist in the associated covariant classical mechanics. In this paper, we explore these difficulties through an examination of the classical. Coulomb problem in the framework of off-shell electrodynamics. As the local gauge theory of a covariant quantum mechanics with evolution paratmeter τ, off-shell electrodynamics constitutes a dynamical theory of ppacetime events, interacting through five τ-dependent pre-Maxwell potentials. We present a straightforward solution of the classical (...) equations of motion, for a test event traversing the field induced by a “fixed” event (an event moving uniformly along the time axis at a fixed point in space). This solution is seen to be unsatisfactory, and reveals the essential difficulties in the formalism at the classical levels. We then offer a new model of the particle current—as a certain distribution of the event currents on the worldline—which eliminates these difficulties and permits comparison of classisical off-shell electrodynamics with the standard Maxwell theory. In this model, the “fixed” event induces a Yukawa-type potential, permitting a semiclassical identification of the pre-Maxwell time scale λ with the inverse mass of the intervening photon. Numerical solutions to the equations of motion are compared with the standard Maxwell solutions, and are seen to coincide when λ≳10−6 seconds, providing an initial estimate of this parameter. It is also demonstrated that the proposed model provides a natural interpretation for the photon mass cut-off required for the renormalizability of the off-shell quantum electrodynamics. (shrink)

The first part of this paper examines the practice of informed treatment decisions in the protective medical system in China today. The second part examines how health care professionals in China perceive and carry out their responsibilities when relaying information to vulnerable patients, based on the findings of an empirical study that I had undertaken to examine the moral experience of nurses in practice situations. In the Chinese medical ethics tradition, refinement [jing] in skills and sincerity [cheng] in relating to (...) patients are two cardinal virtues that health care professionals are required to possess. This notion of absolute sincerity carries a strong sense of parental protectiveness. The empirical findings reveal that most nurses are ambivalent about telling the truth to patients. Truth-telling would become an insincere act if a patient were to lose hope and confidence in life after learning of his or her disease. In this system of protective medical care, it is arguable as to whose interests are being protected: the patient, the family or the hospital. I would suggest that the interests of the hospital and the family members who legitimately represent the patient's interests are being honoured, but at the expense of the patient's right to know.

In the context of a covariant mechanics with Poincaré-invariant evolution parameter τ, Sa'ad, Horwitz, and Arshansky have argued that for the electromagnetic interaction to be well posed, the local gauge function of the field should include dependence on τ, as well as on the spacetime coordinates. This requirement of full gauge covariance leads to a theory of five τ-dependent gauge compensation fields, which differs in significant aspects from conventional electrodynamics, but whose zero modes coincide with the Maxwell theory. The pre-Maxwell (...) fields may exchange mass with charged particles, permitting pair annihilation even at the classical level. The total mass-energy-momentum tensor of the fields and particles is conserved. The Green's functions for the fields provide spacelike and timelike support for correlations, as well as lightlike propagation. A τ-integration of the fields—singling out the massless photons—recovers the standard Maxwell theory, which then has the character of an equilibrium limit of the underlying microscopic dynamics. The pre-Maxwell theory also turns out to be the solution of the inverse problem in variational mechanics: it is shown to be the most general local gauge theory consistent with unconstrained commutation relations in four dimensions. Posed in this framework, the extension to n-dimensions, curved background space, and non-abelian gauge symmetry becomes straightforward. (shrink)

Purpose: Yerkish is an artificial language created in 1971 for the specific purpose of exploring the linguistic potential of nonhuman primates. The aim of this paper is to remind the research community of some important issues and concepts related to Yerkish that seem to have been forgotten or appear to be distorted. These are, particularly, its success, its promising aspects for future research and last but not least that it was Ernst von Glasersfeld who invented Yerkish: he coined the term (...) “lexigrams,” created the first 120 of them and designed the grammar that regulated their combination. Design: The first part of this paper begins with a short outline of the context in which the Yerkish language originated: the original LANA project. It continues by presenting the language itself in more detail: first, its design, focusing on its “lexigrams” and its “correlational” grammar, and then its use by the chimpanzee Lana in formulating sentences. The second part gives a brief introduction to the foundation of Yerkish in Silvio Ceccato’s Operational Methodology, particularly his idea of the correlational structure of thought and concludes with the main insights that can be derived from the Yerkish experiment seen in the light of Operational Methodology. Findings: Lana’s success in language learning and the success of Yerkish during the past decades are probably due to the characteristics of Yerkish, particularly its foundation in operational methodology. The operation of correlation could be what constitutes thinking in a chimpanzee and an attentional system could be what delivers the mental content that correlation assembles into triads and networks. Research implications: Since no other assessment or explanation of Lana’s performances has considered these foundational issues, a new research project or program should validate the above-mentioned hypotheses, particularly the correlational structure of chimpanzee thinking.

The article tries to show that both resolution of the mind-body problem and adequate description of the phenomenal body depend upon the ontology presupposed in offering such a resolution or description. a detailed analysis of sartre's treatment of the body demonstrates that his failures are a result of his neo-cartesian ontology. both the critique and the resolution proposed toward the end take their departure from merleau- ponty's thesis of the ontological primacy of phenomena.
