For a world mired in catastrophe, nothing could be more urgent than the question of survival. In this theoretically and methodologically groundbreaking book, Adam Y. Stern calls for a critical reevaluation of survival as a contemporary regime of representation. In Survival, Stern asks what texts, what institutions, and what traditions have made survival a recognizable element of our current political vocabulary. The book begins by suggesting that the interpretive key lies in the discursive prominence of "Jewish survival." Yet (...) the Jewish example, he argues, is less a marker of Jewish history than an index of Christianity's impact on the modern, secular, political imagination. With this inversion, the book repositions Jewish survival as the supplemental effect and mask of a more capacious political theology of Christian survival. The argument proceeds by taking major moments in twentieth-century philosophy, theology, and political theory as occasions for collecting the scattered elements of survival's theological-political archive. Through readings of canonical texts by secular and Jewish thinkers—Hannah Arendt, Walter Benjamin, Franz Rosenzweig, and Sigmund Freud—Stern shows that survival belongs to a history of debates about the sovereignty and subjection of Christ's body. Interrogating survival as a rhetorical formation, the book intervenes in discussions about biopolitics, secularism, political theology, and the philosophy of religion. (shrink)

Plato's "Ion," despite its frail frame and traditionally modest status in the corpus, has given rise to large exegetical claims. Thus some historians of aesthetics, reading it alongside page 205 of the Symposium, have sought to identify in it the seeds of the post-Kantian notion of 'art' as non-technical making, and to trace to it the Romantic conception of the poet as a creative genius. Others have argued that, in the "Ion," Plato has Socrates assume the existence of a technē (...) of poetry. In this article, these claims are challenged on exegetical and philosophical grounds. To this effect, Plato's use of poiētēs and poiēsis in the Symposium is analysed, the defining criteria of technē in the "Ion" and other dialogues are identified and discussed, and the 'Romantic' interpretation of the dialogue is traced to Shelley's tendentious translation of it. These critical developments lead to what is presented as a more faithful reading of the dialogue. In the "Ion," it is claimed, Plato seeks to subvert the traditional status of poetry by having Socrates argue that poetry is both non-rational and non-cognitive in nature. In the third part of the article, suggestions are offered as to the contribution made by the "Ion" to the evolution of Plato's reflections on poetic composition, and particularly as to the reasons which later induced Plato to substitute the concept of mimesis for that of inspiration in his account of poetry.

For the last 40 years or so the is/ought gap, the fact/value distinction and the naturalistic fallacy have figured prominently in ethical debates. This longevity, however, has had an adverse side effect. So familiar have they become that they—and their respective rationales—have tended to become blurred. It is the purpose of this paper to explain why they should be kept distinct.

The status of beauty in Plotinus' metaphysics is unclear: is it a Form in Intellect, the Intelligible Principle itself, or the One? Basing themselves on a number of well-known passages in the "Enneads," and assuming that Plotinus' Forms are similar in function and status to Plato's, many scholars hold that Plotinus theorized beauty as a determinate entity in Intellect. Such assumptions, it is here argued, lead to difficulties over self-predication, the interpretation of Plotinus's rich and varied aesthetic terminology and, most (...) of all, the puzzling dearth of references, in the whole of the "Enneads," to a Form of Beauty. A detailed reading of VI.7.32 and 33 reveals that, in these two crucial passages at least, Plotinus adopts an aesthetic approach to the One and that, far from confining Beauty to Intellect, he equates the One, the Good and the Beautiful. This reading is here supported not only by an analysis of the text but also by a consideration of the semantic differences between μορφή and ε[unrepresentable symbol]δος, the inter-relatedness, in Plotinus' philosophy, of the concepts of love and value, and the exclusion of beauty from the πρ[unrepresentable symbol]τα γένη. In turn, the exegesis of VI.7.32 and 33 raises the issue of the significance for aesthetics understood in the narrow sense of the word, of Plotinus's ontology of beauty. It is here claimed that in so far as sensible beauty, both artistic and natural, can be nothing else than an effect of the shaping action of the Forms and a reflection of their radiance, singular or global, it should not be held that Plotinus had an aesthetics in the modern sense of this term.

In the absence of effective judicial remediation mechanisms after business-related human rights violations, companies themselves are expected to establish remediation procedures for affected victims and communities. This is a challenge for both companies and victims since comprehensive company-based grievance mechanisms are currently missing. In this paper, we explore how companies can provide effective remediation after human rights violations. Accordingly, we critically assess two different approaches to conflict resolution, alternative dispute resolution and restorative justice, for their potential to provide dialogue-based, non-judicial (...) remediation. We argue that remedy through agreement-driven ADR mechanisms risks marginalizing the interests and concerns of victims and affected community members, particularly in weak institutional contexts. Hence, we develop a dialogue-driven framework for corporate remediation of human rights violations grounded on RJ principles. This restorative framework provides a comprehensive CGM that focuses on the harms and needs of victims and aims at restoring justice through restorative dialogue. Based on a prompt discovery and a thorough investigation of the grievance, companies should design and prepare the remediation process together with victims, offenders and affected community members. Through restorative dialogue with the affected parties about the circumstances and impacts of the wrongdoing, companies can repair the harm, regain legitimacy amongst stakeholders as well as transform their business practices to avoid future human rights violations.

In lieu of an abstract, here is a brief excerpt of the content:Kennedy Institute of Ethics Journal 12.3 (2002) 299-303 [Access article in PDF] Bioethics Inside the Beltway What Should IRBs Consider When Applying the Privacy Rule to Research? Julie Waltz Gerlach In 1996, Congress mandated the establishment of standards for the privacy of individually identifiable health information through the Health Insurance and Portability and Accountability Act of 1996 (HIPAA). Until the establishment of HIPAA, personal health information could be (...) distributed without notice or consent for reasons that had nothing to do with a patient's medical treatment or health care reimbursement. Patient information held by a health plan could be passed on to a lender who then might deny the patient's application for a home mortgage or a credit card or to an employer who might use it for personnel decisions. Congress failed to meet its 21 August 1996 deadline established by HIPAA to pass privacy legislation; the Act passed the responsibility to Department of Health and Human Services (DHHS). On 28 December 2000, the Secretary of Health and Human Services released final privacy regulations relating to the protection of patients' individually identifiable health information. The "Standards for Privacy of Individually Identifiable Health Information" (Privacy Rule/current) took effect 14 April 2001. As required by HIPAA, the Privacy Rule established conditions for the collection, use, and disclosure of protected health information by covered entities for research purposes. Covered entities, defined as health plans, health care clearinghouses, and health care providers that engage electronically in a wide range of financial and administrative transactions related to payment and reimbursement, must comply by 14 April 2003 (DHHS 2000, p. 82462). To ensure that the provisions of the final rule provide strong privacy protection without hindering access to health care, the Department of Health and Human Services (DHHS 2002, p. 14776) has proposed modifications to the Privacy Rule.The final Privacy Rule (DHHS 2001) grants substantial rights to individuals/research participants to be informed of how their protected health information is maintained and how that information may be used or disclosed. It also defines individual's/research participants' rights with regard to gaining access to information about themselves, when such information is held by covered entities. [End Page 299]The Privacy Rule requires researchers either to receive authorization from individuals/research participants to collect, use, and disclose protected health information, or to obtain a waiver of authorization that is approved by an institutional review board (IRB) or Privacy Board, or to use de-identified data. Section 164.508 of the Privacy Rule, entitled "Use and Disclosures for Which an Authorization Is Required," describes how IRBs will be directly affected. The rule focuses not just on research but on the overall privacy of all identifiable health information. Institutions have the option of adding these required duties to IRBs or establishing "privacy boards." Privacy boards, as defined by the Privacy Rule, are to be composed of members with varying backgrounds and professional competency to review the effect of the research protocol on the individual/research participant's privacy rights. The board must include at least one member who is not affiliated with the covered entity, or any entity conducting or sponsoring the research, and not related to any person who is affiliated with such entities. Board members cannot participate in the review of any research project in which the member has a conflict of interest.The basic concepts and tenets of privacy and confidentiality are well known to IRBs in the United States, which operate under the Common Rule (45 CFR 46) and/or the Food and Drug Administration's (FDA) human subject protection regulations. Both sets of regulations require IRBs to ensure that risks (including privacy risks) are minimized. Under these regulations, IRBs must consider the confidentiality of research data and whether researchers should have access to confidential medical information. IRBs also must review the consent form as a process of communication that will inform research subjects about the research study.One noteworthy aspect of the Privacy Rule is its application to all research regardless of funding source. Currently, research funded by... (shrink)

Psychological safety is a shared belief among team members that it is safe to take interpersonal risks. It can enhance team learning, experimentation with new ideas, and team performance. Considerable research has examined the positive effects of PS in diverse organizational contexts and is now shifting its focus toward exploring the nature of PS itself. This study aims to enhance our understanding of PS antecedents and development over time. Based on the model of team faultlines and research on team diversity, (...) we examined the effects of demographic faultlines, team member personality, and member competencies on the development of PS. Over 5 months, 61 self-managed teams assessed their PS at the beginning, midpoint, and end of a research project. Results of a multilevel growth curve model show that PS decreased from project beginning to end. Initial levels of PS were especially low when teams had strong demographic faultlines and when team members differed in neuroticism. PS decreased more strongly over time when team members were diverse in agreeableness and assessed their task-related competencies to be relatively high. Our study identifies time and team composition attributes as meaningful predictors for the development of PS. We present ideas for future research and offer suggestions for how and when to intervene to help teams strengthen PS throughout their collaboration. (shrink)

Women’s capacity to reproduce varies over the life span, and developmental goals such as family formation are age-graded and shaped by social norms about the appropriate age for completing specific developmental tasks. Thus, a woman’s age may be linked to her ideas about what an ideal partner should be like. With the goals of replicating and extending prior research, in this study we examined the role of age in women’s partner preferences across the globe. We investigated associations of age with (...) ideal long-term partner preferences in a cross-cultural sample of 17,254 single (i.e., unpartnered) heterosexual women, ages 18 to 67, from 147 countries. Data were collected via an online questionnaire, the Ideal Partner Survey. Confirming our preregistered hypotheses, we found no or only negligible age effects on preferences for kindness-supportiveness, attractiveness, financial security-successfulness, or education-intelligence. Age was, however, positively associated with preferences for confidence-assertiveness. Consistent with family formation goals, age was associated with an ideal partner’s parenting intentions (high until approximately age 30, then decreasing afterward). Age range deemed acceptable (and in particular, the discrepancy between one’s own age and the minimum ideal age of a partner) increased with age. This latter pattern also replicated in exploratory analyses based on subsamples of lesbian and bisexual women. In summary, age has a limited impact on partner preferences. Of the attributes investigated, only preference for confidence-assertiveness was linked with age. However, age range deemed acceptable and an ideal partner’s parenting intention, a dimension mostly neglected in earlier research, substantially vary with age. (shrink)

Online social networks (OSN) have become a part of our daily lives whether they are used for socialization and communication or to promote business interests. OSN have become an important tool for businesses to advertise, create brand awareness, and promote their products and services. Business use of OSN for advertising purposes is highly reliant on targeted ads which display advertisements to OSN users based on their demographics and use of OSN, apps, and websites. Thus, one of the most valuable commodities (...) of OSN is the population of users and the information they share. To investigate the relationship between OSN site use, use of privacy settings, and how they relate to profile disclosure, a model is built based on the theory of reasoned action and the privacy calculus model. To validate the model, a survey is conducted and the results are analyzed with partial least squares. Risk and benefit were both shown to be significant antecedents of attitude. Both attitude and subjective norm, from the theory of reasoned action model, significantly affected OSN site use, while omitting intentions. OSN site use was significantly related to both profile disclosure and use of privacy settings. Last, use of privacy settings significantly affected profile disclosure. These results imply that use of privacy settings does not decrease the rate of disclosure. Giving users tools to protect their private information is important in protecting the privacy of OSN users, and it will lead to increases in safe disclosure of information helping OSN target ads effectively.

Why is social bias and its depressing effects on low-status or low-performing groups exaggerated? We show that the higher intelligence of academics has at best a very weak effect on reducing their bias, facilitates superficially justifying their biases, and may make them better at understanding the benefits of social conformity in general and competitive altruism specifically. We foresee a surge in research examining these mechanisms and recommend, meanwhile, reviving and better observing scientific ideals.

This edited volume seeks to provide guidance on how we can approach questions of governing and agency--particularly those who endeavour to embark on grounded empirical research--by rendering explicit some key challenges, tensions, dilemmas, and confluences that such endeavours elicit. Indeed, the contributions in this volume reflect the growing tendency in governmentality studies to shift focus to empirically grounded studies. The volume thus explicitly aims to move from theory to practice, and to step back from the more top-down governmentality studies approach (...) to one that examines how one can/does study how relations of power affect lives, experience and agency. This book offers insight into the intricate relations between the workings of governing and (the possibility for) people's agency on the one hand, and about the possible effects of our attempts to engage in such studies on the other. In numerous ways, and from different starting points, the contributions to this volume provide thoughtful insights into, and creative suggestions for, how to work with the methodological challenges of studying the agency of being governed.This work will be of great interest to students and scholars of international relations, global governance and research methods.

We also examine good reasons for having an ambivalent attitude concerning the later permanence in life of these archaic forms of association, and the coexistence of such intuitive but informal thinking with logical and rigorous reasoning. At the one hand, magical thinking seems to serve the creative mind, working as a natural vehicle for new ideas and innovative insights, (...) and giving form to heuristic arguments. At the other hand, it is inherently difficult to control, lacking effective mechanisms needed for rigorous manipulation. Our discussion is illustrated with many examples from the Hebrew Bible, and some final examples from modern science. (shrink)

Designing policy for climate change requires analyses which integrate the interrelationship between the economy and the environment. We argue that, despite their dominance in the economics literature and influence in public discussion and policymaking, the methodology employed by Integrated Assessment Models (IAMs) rests on flawed foundations, which become particularly relevant in relation to the realities of the immense risks and challenges of climate change, and the radical changes in our economies that a sound and effective response require. We identify a (...) set of critical methodological problems with the IAMs which limit their usefulness and discuss the analytic foundations of an alternative approach that is more capable of providing insights into how best to manage the transition to net-zero emissions.

This piece continues the tradition of arguments by John Lucas, Roger Penrose and others to the effect that the human mind is not a machine. Kurt Gödel thought that the intensional paradoxes stand in the way of proving that the mind is not a machine. According to Gödel, a successful proof that the mind is not a machine would require a solution to the intensional paradoxes. We provide what might seem to be a partial vindication of Gödel and show (...) that if a particular solution to the intensional paradoxes is adopted, one can indeed give an argument to the effect that the mind is not a machine.

Plotinus’s theory of dual selfhood has ethical norms built into it, all of which derive from the ontological superiority of the higher (or undescended) soul in us overthe body-soul compound. The moral life, as it is presented in the Enneads, is a life of self-perfection, devoted to the care of the higher self. Such a conception of morality is prone to strike modern readers as either ‘egoistic’ or unduly austere. If there is no doubt that Plotinus’s ethics is exceptionally austere, (...) it will be argued below that it is not ‘egoistic.’ To that effect, the following questions will be addressed: Are the virtues, civic as well as purificatory, mere means to Plotinus’s metaphysically conceived ethical goal? To what extent must the lower self abnegate itself so as to enable the higher self to ascend to Intellect and beyond? And if self-perfection lies at the centre of the Plotinian moral life, is there any conceptual room left in it for other-regarding norms of conduct? A close reading of selected passages from Plotinus’s tractate I.2[19] On Virtues and tractate VI.8[39] On Free Will and the Will of the One will, it is claimed, bring elements of answer to these questions.

Though common sense says that causes must temporally precede their effects, the hugely influential interventionist account of causation makes no reference to temporal precedence. Does common sense lead us astray? In this paper, I evaluate the power of the commonsense assumption from within the interventionist approach to causal modeling. I first argue that if causes temporally precede their effects, then one need not consider the outcomes of interventions in order to infer causal relevance, and that one can instead use temporal (...) and probabilistic information to infer exactly when X is causally relevant to Y in each of the senses captured by Woodward’s interventionist treatment. Then, I consider the upshot of these findings for causal decision theory, and argue that the commonsense assumption is especially powerful when an agent seeks to determine whether so-called “dominance reasoning” is applicable.

This paper examines college athletes’ perceived support for concussion reporting from coaches and teammates and its variation by year-in-school, finding significant differences in perceived coach support. It also examines the effects of perceived coach support on concussion reporting behaviors, finding that greater perceived coach support is associated with fewer undiagnosed concussions and returning to play while symptomatic less frequently in the two weeks preceding the survey. Coaches play a critical role in athlete concussion reporting.

In this revolutionary work, the author sets the stage for the science of the 21st Century, pursuing an unprecedented synthesis of fields previously considered unrelated. Beginning with simple classical concepts, he ends with a complex multidisciplinary theory requiring a high level of abstraction. The work progresses across the sciences in several multidisciplinary directions: Mathematical logic, fundamental physics, computer science and the theory of intelligence. Extraordinarily enough, the author breaks new ground in all these fields. In the field of fundamental physics (...) the author reaches the revolutionary conclusion that physics can be viewed and studied as logic in a fundamental sense, as compared with Einstein's view of physics as space-time geometry. This opens new, exciting prospects for the study of fundamental interactions. A formulation of logic in terms of matrix operators and logic vector spaces allows the author to tackle for the first time the intractable problem of cognition in a scientific manner. In the same way as the findings of Heisenberg and Dirac in the 1930s provided a conceptual and mathematical foundation for quantum physics, matrix operator logic supports an important breakthrough in the study of the physics of the mind, which is interpreted as a fractal of quantum mechanics. Introducing a concept of logic quantum numbers, the author concludes that the problem of logic and the intelligence code in general can be effectively formulated as eigenvalue problems similar to those of theoretical physics. With this important leap forward in the study of the mechanism of mind, the author concludes that the latter cannot be fully understood either within classical or quantum notions. A higher-order covariant theory is required to accommodate the fundamental effect of high-level intelligence. The landmark results obtained by the author will have implications and repercussions for the very foundations of science as a whole. Moreover, Stern's Matrix Logic is suitable for a broad spectrum of practical applications in contemporary technologies. (shrink)

This article considers Christine Korsgaard's argument for the value of humanity, and the role that her transcendental argument plays in this, to the effect that an agent must value her own humanity.

Ramsey famously condemned discounting “future enjoyments” as “ethically indefensible”. Suppes enunciated an equity criterion which, when social choice is utilitarian, implies giving equal weight to all individuals’ utilities. By contrast, Arrow (Contemporary economic issues. International Economic Association Series. Palgrave Macmillan, London, 1999a; Discounting and Intergenerational Effects, Resources for the Future Press, Washington DC, 1999b) accepted, perhaps reluctantly, what he called Koopmans’ (Econometrica 28(2):287–309, 1960) “strong argument” implying that no equitable preference ordering exists for a sufficiently unrestricted domain of infinite utility (...) streams. Here we derive an equitable utilitarian objective for a finite population based on a version of the Vickrey–Harsanyi original position, where there is an equal probability of becoming each person. For a potentially infinite population facing an exogenous stochastic process of extinction, an equitable extinction biased original position requires equal conditional probabilities, given that the individual’s generation survives the extinction process. Such a position is well-defined if and only if survival probabilities decline fast enough for the expected total number of individuals who can ever live to be finite. Then, provided that each individual’s utility is bounded both above and below, maximizing expected “extinction discounted” total utility—as advocated, inter alia, by the Stern Review on climate change—provides a coherent and dynamically consistent equitable objective, even when the population size of each generation can be chosen.

Rent-control laws limiting the rents private landlords can charge tenants are controversial in the United States. Critics have condemned rent control’s mandated wealth transfer from landlords to tenants, and economists have decried its negative effects on rental supply and quality. With the advent of the sharing economy, rent-controlled tenants can rent out their below-market units for short durations at market-level or premium prices, a practice I term “rent control sharing.” The reaction to rent-controlled tenants pocketing money from Airbnb and other (...) homesharing sites at the expense of their hapless landlords has been negative. Yet, the sharing economy has not changed an essential feature of rent control: the redistribution of wealth from landlord to tenant. Instead, Airbnb and similar platforms have altered the form of the redistribution and the legal relations between landlord and tenant, and increased the salience of the wealth transfer from landlord to tenant. As a result, rent control sharing collides with public preferences for in-kind redistribution and stronger legal protections for property used personally or intimately. This Article explores how rent control sharing accentuates some of the flaws of rent control and fuels the debate over rent control’s future. (shrink)

I contend that though Pippin argues persuasively that the most trenchant critics of modernity ? Nietzsche and Heidegger ? failed to break free of modernity, it remains unclear whether the unending character of modernity is thereby defended as an unfinished project, or rather is a fate to which we are condemned. The thesis of my paper is that the ambiguity is traceable to Pippin's Hegelian narrative of legitimation. On his view, the demands of modern self?consciousness inaugurated by Kant and radicalized (...) by Hegel prohibit every appeal to a given, even where the given is construed as contingent historical shifts, or perspectives, or Ereignisse. But this rejection of appeals to something outside the narrative of legitimation implies that even the significance of the narrative can only be an effect of the narrative itself. But if this is true, there is on Pippin's own terms no way of establishing the significance of a narrative about modernity and hence no reason for finding it compelling. Thus the very radicalization of the Kantian critique of dogmatism that Pippin claims is the hallmark of modernity renders unavailable the legitimation of modernity. (shrink)

Background Despite the bourgeoning of digital tools for bioethics research, education, and engagement, little research has empirically investigated the impact of interactive visualizations as a way to translate ethical frameworks and guidelines. To date, most frameworks take the format of text-only documents that outline and offer ethical guidance on specific contexts. This study’s goal was to determine whether an interactive-visual format supports frameworks in transferring ethical knowledge by improving learning, deliberation, and user experience.Methods An experimental comparative study was conducted with (...) a pre-, mid-, and post-test design using the online survey platform Qualtrics. Participants were university based early-stage health researchers who were randomly assigned to either the control condition (text-only document) or the experimental condition (interactive-visual). The primary outcome variables were learning, (measured using a questionnaire), deliberation (using cases studies) and user experience (measured using the SED/UD Scale). Analysis was conducted using descriptive statistics and mixed-effects linear regression.Results Of the 80 participants, 44 (55%) used the text-only document and 36 (45%) used the interactive-visual. Results of the knowledge-test scores showed a statistically significant difference between participants’ post-test scores, indicating that the interactive-visual format better supported understanding, acquisition, and application of the framework’s knowledge. Findings from the case studies showed both formats supported ethical deliberation. Results further indicated the interactive-visual provided an overall better episodic and remembered user experience compared with the text-only document.Conclusions Our findings show that ethical frameworks formatted with interactive and visual qualities provide a more pleasing user experience and are effective formats for ethics learning and deliberation. These findings have implications for practitioners developing and deploying ethical frameworks and guidelines (e.g., in educational or employee-onboarding settings), in that the knowledge generated can lead to more effective dissemination practices of normative guidelines and health data ethics concepts.

Growth factor receptor tyrosine kinases (RTKs), such as the fibroblast growth factor receptor (FGFR), play a major role in how cells communicate with their environment. FGFR signaling is crucial for normal development, and its misregulation in humans has been linked to developmental abnormalities and cancer. The precise molecular mechanisms by which FGFRs transduce extracellular signals to effect specific biologic responses is an area of intense research. Genetic analyses in model organisms have played a central role in our evolving understanding (...) of these signal transduction cascades. Genetic studies in the nematode C. elegans have contributed to our knowledge of FGFR signaling by identifying genes involved in FGFR signal transduction and linking their gene products together into signaling modules. This review will describe FGFR-mediated signal transduction in C. elegans and focus on how these studies have contributed to our understanding of how FGFRs orchestrate the assembly of intracellular signaling pathways.

In 1975, two experimental groups have independently observed the \-symmetry of neutrons’ spin, when passing through a static magnetic field, using a three-blade interferometer made from a single perfect Si-crystal. In this article, we provide a complete analysis of the experiment, both from a theoretical and conceptual point of view. Firstly, we solve the Schrödinger equation in the weak potential approximation, to obtain the amplitude of the refracted and forward refracted beams, produced by the passage of neutrons through one of (...) the three plates of the LLL interferometer. Secondly, we analyze their passage through a static magnetic field region. This allows us to find explicit expressions for the intensities of the four beams exiting the interferometer, two of which will be interfering and show a typical \-symmetry, when the strength of the magnetic field is varied. In the last part of the article, we provide a conceptual analysis of the experiment, showing that a neutron’s phase change, when passing through the magnetic field, is due to a longitudinal Stern–Gerlach effect, and not to a Larmor precession. We also emphasize that these experiments do not prove the observability of the sign change of the wave function, when a neutron is \ rotated, but strongly indicate that the latter, like any other elementary “particle,” would be a genuinely non-spatial entity.

The discussion of the recently derived quantum Hamilton equations for a spinning particle is extended to spin measurement in a Stern–Gerlach experiment. We show that this theory predicts a continuously changing orientation of the particles magnetic moment over the course of its motion across the Stern–Gerlach apparatus.

Furthermore, the Einstein–Podolsky–Rosen–Bohm thought experiment is investigated, and the violation of Bells’s inequalities is reproduced within (...) this stochastic mechanics approach. The origin of the violation of Bell’s inequalities is traced to the the non-local nature of the velocity fields for an entangled state in the stochastic formalism, which is a result of a non-separable probability distribution of the considered particles.

We present a description of the Stern–Gerlach type experiments using only the concepts of classical electrodynamics and the Newton’s equations of motion. The quantization of the projections of the spin (or the projections of the magnetic dipole) is not introduced in our calculations. The main characteristic of our approach is a quantitative analysis of the motion of the magnetic atoms at the entrance of the magnetic field region. This study reveals a mechanism which modifies continuously the orientation of (...) the magnetic dipole of the atom in a very short time interval, at the entrance of the magnetic field region. The mechanism is based on the conservation of the total energy associated with a magnetic dipole which moves in a non uniform magnetic field generated by an electromagnet. A detailed quantitative comparison with the (1922) Stern–Gerlach experiment and the didactical (1967) experiment by J.R. Zacharias is presented. We conclude, contrary to the original Stern–Gerlach statement, that the classical explanations are not ruled out by the experimental data. (shrink)

A criticism of a recent article published in this journal, claiming to have reached a classical description of the Stern-Gerlach phenomenon, is presented here. The author of the article, among other mistakes, wrongly writes the total energy of each silver atom and, moreover, presents a nonsensical equation, from which his results and the conclusion of his article are derived.

Different or conflicting accounts of the same episode in the history of science may arise from viewing that episode from different perspectives. The metaphor suggests that conflicting accounts can be seen as complementary, constructing a multi-dimensional understanding, if the different perspectives can be coordinated. As an example, I discuss different perspectives on the Stern-Gerlach experiment. In a static interpretation, the SGE has been viewed as an experiment that allows the determination of the magnetic moment of silver atoms. Based (...) on the concept of magnetic momentum arising from orbital angular momentum, the original experiment was designed in 1922 as an experimentum crucis to decide between Bohr’s quantum theory and classical electromagnetic theory, and its outcome was interpreted as a confirmation of the Bohr-Sommerfeld quantum postulates. After the advent of quantum mechanics, the SGE was reinterpreted in terms of magnetic moment arising from the electron’s spin angular momentum. In a dynamical interpretation, physicists have asked for the physical mechanism responsible for the quantization of the angular momentum with respect to the direction of the magnetic field. Although different suggestions were explored, none was ever accepted as fully satisfactory. Today this difficulty is seen as a paradigmatic instance of the unsolved quantum measurement problem.

It is pointed out that ordinary quantum mechanics as a classical field theory cannot account for the wave function collapse if it is not seen within the framework of field quantization. That is needed to understand the particle structure of matter during wave function evolution and to explain the collapse as symmetry breakdown by detection. The decay of a two-particle bound s state and the Stern-Gerlach experiment serve as examples. The absence of the nonlocality problem in Bohm’s version (...) of the EPR arrangement favours the approach described. (shrink)

Exact wavelet solutions of the wave equation for accelerating potentials are found and applied to single individual events in Stern-Gerlach experiment.

The well-known Stern-Gerlach device is proposed here for determination of a particle spin state instead of using it for measurement of spin observables. It is shown that measurement of particle momentum distributions (before and after the action of the device magnetic field) allows one to determine the particle initial spin state in the case of an arbitrary spin value. It is demonstrated that one cannot use for this purpose the usual treatment of the Stern-Gerlach experiment based (...) on the entanglement of spin and spatial states. (shrink)

We present, in various limits, analytical expressions for the center-of-mass wave function of a spin-1/2 atom as it is deflected by a Stern-Gerlach apparatus.
