In March 2013, after reading articles about the questionable marketing styles of Victoria's Secret, targeted especially to younger demographics, Dolive penned an open letter calling for companies to not view girls as objects but as human beings. The letter came out of his desire to instill in his own daughter that love, care, and acceptance should not be based on articles of clothing. The letter was viewed nearly four million times (on his site alone) in about a week-and-a-half, and (...) dozens of other news organizations and publications picked up the story. Dolive was interviewed by national news publications and appeared on CNN and Headline News. The letter was a catalyst for conversations about body image, marketing, and how the church could affect change and confidence in people of all ages. Seeking Imperfection explores these false messages and takes a look at people from the Bible who, despite their flaws, were still able to serve God faithfully. (shrink)

Recent sociological/philosophical treatments of expertise, best represented by the work of Steve Fuller, attempt to (1) reduce displays of expertise to sophistic exercises of discretionary power, and (2) refute the claim that because laypeople are epistemically inferior to experts, it is rational to defer to an expert's opinion rather than making up one's own mind. But upon inspection, Fuller fails to provide reasonable grounds for liberating laypeople from the tyranny of cognitive authoritarianism. Rather, he presents a patronizing description of the (...) expert‐lay relation, one that actually makes the public seem more ignorant than is warranted. (shrink)

Paul Feyerabend is famous for presenting a scathing indictment of modern experts as a threat to democracy. While commentators have questioned the accuracy of his portrayal of experts, they have not assessed the accuracy of his depiction of laypeople. Although Feyerabend has political reasons for wanting to demythologize grandiose notions of expertise, his political project hinders clear thinking about the question by idealizing the alternative lay perspective.

“Run-in” and “washout” periods involving the withholding of medication are widely used in drug research trials in pursuit of both patient safety and scientific reliability. Such no-medication periods can be justified ethically provided that they are apparent to patients, who can thereby properly consent to undergoing them. Less widespread, but still common, is the practice of “single blinding” no-medication periods, concealing them from patients by means of placebo. Whilst all placebos involve a measure of concealment, their use is typically justified (...) in drug research trials by their preserving the uncertainty generated by the random allocation of different treatments within a drug trial; and by the researchers openly declaring both the randomisation process and the chances of receiving placebo. In the single blind placebo “run-in” or “washout”, neither of these conditions is met.This paper considers three possible defences of the practice of using single blind placebo “run-ins” or “washouts” and finds them all to fail; the practice appears ethically unjustified.

Patient-based outcome measures are increasingly important in health care evaluations, often through the use of paper-based questionnaires. The likely impact of questionnaires upon patients is not often considered and therefore, the balance of benefit and harm not fully explored. Harms that might accrue for research staff are even less frequently considered. This paper describes the use of postal questionnaires within a study of breast disease management in primary care. Questionnaire responses are used to describe the nature of discomfort or harms (...) that may occur in such studies. Ethical issues raised by the harms are discussed in relation to the benefits of the study. Practical suggestions for reducing harm to patients are proposed. A secondary consideration, discomfort to the researcher, is also identified and suggestions made to reduce its effect. Finally, the role of research questionnaires as a study intervention is discussed. (shrink)

"Effective Weight Loss presents 25 detailed sessions of an empirically supported, cognitive-behavioral treatment package called Acceptance-Based Behavioral Treatment. The Clinician Guide is geared towards helping administer treatment, and the companion Workbook provides summaries of session content, exercises, worksheets, handouts, and assignments for patients and clients receiving the treatment"--.

The obesity epidemic is one of the most serious public health threats confronting the nation and the world. The majority of overweight individuals want to lose weight, but the overall success of self-administered diets and commercial weight loss programs is very poor. Scientific findings suggest that the problem boils down to adherence. The dietary and physical activity recommendations that weight loss programs promote are effective; however, people have difficulty initiating and maintaining changes. Effective Weight Loss presents 25 detailed sessions of (...) an empirically supported, cognitive-behavioral treatment package called Acceptance-Based Behavioral Treatment. The foundation of this approach is comprised of the nutritional, physical activity, and behavioral components of the most successful, gold-standard behavioral weight loss programs. These components are synthesized with acceptance, willingness, behavioral commitment, motivation, and relapse prevention strategies drawn from a range of therapies. ABT is based on the idea that specialized self-control skills are necessary for weight control, given our innate desire to consume delicious foods and to conserve energy by avoiding physical activity. These self-control skills revolve around a willingness to choose behaviors that may be perceived as uncomfortable, for the sake of a more valuable objective. The Clinician Guide is geared towards helping administer treatment, and the companion Workbook provides summaries of session content, exercises, worksheets, handouts, and assignments for patients and clients receiving the treatment. The books will appeal to psychologists, primary care physicians, nutritionists, dieticians, and other clinicians who counsel the overweight. (shrink)

Dreyfus's model of expert skill acquisition is philosophically important because it shifts the focus on expertise away from its social and technical externalization in STS, and its relegation to the historical and psychological context of discovery in the classical philosophy of science, to universal structures of embodied cognition and affect. In doing so he explains why experts are not best described as ideologues and why their authority is not exclusively based on social networking. Moreover, by phenomenologically analyzing expertise from a (...) first person perspective, he reveals the limitations of, and sometimes superficial treatment that comes from, investigating expertise from a third person perspective. Thus, he shows that expertise is a prime example of a subject that is essential to science but can only be fully elaborated with the aid of phenomenological tools. However, both Dreyfus's descriptive model and his normative claims are flawed due to the lack of hermeneutical sensitivity. He assumes an expert's knowledge has crystallized out of contextual sensitivity plus experience, and that an expert has shed, during the training process, whatever prejudices, ideologies, hidden agendas, or other forms of cultural embeddedness, that person might have begun with. One would never imagine, from Dreyfus's account, that society could possibly be endangered by experts, only how society's expectations and actions could endanger experts. The stories of actual controversies not only shows things do not work the way Dreyfus claims, but also that it would be less salutary if they did. Such stories amount to counterexamples to Dreyfus's normative claims, and point to serious shortcomings in his arguments. (shrink)

Recent advances in wireless data transmission technology have the potential to revolutionize clinical neuroscience. Today sensing-capable electrical stimulators, known as “bidirectional devices”, are used to acquire chronic brain activity from humans in natural environments. However, with wireless transmission come potential failures in data transmission, and not all available devices correctly account for missing data or provide precise timing for when data losses occur. Our inability to precisely reconstruct time-domain neural signals makes it difficult to apply subsequent neural signal processing techniques (...) and analyses. Here, our goal was to accurately reconstruct time-domain neural signals impacted by data loss during wireless transmission. Towards this end, we developed a method termed Periodic Estimation of Lost Packets. PELP leverages the highly periodic nature of stimulation artifacts to precisely determine when data losses occur. Using simulated stimulation waveforms added to human EEG data, we show that PELP is robust to a range of stimulation waveforms and noise characteristics. Then, we applied PELP to local field potential recordings collected using an implantable, bidirectional DBS platform operating at various telemetry bandwidths. By effectively accounting for the timing of missing data, PELP enables the analysis of neural time series data collected via wireless transmission—a prerequisite for better understanding the brain-behavior relationships underlying neurological and psychiatric disorders.

Does it matter that the hearts of 'brainstem dead' patients may persist in beating spontaneously? Hostile reactions, to the Danish inclusion of cardiac criteria in the determination of death, betray reductionist views of human life at the core of 'brainstem' conceptions of death. Such views (whether centred on neurological function or on abstractions concerning 'personhood') supplant the richness of human life and death with the poverty of essentialism: and mask the lethal nature of beating-heart organ retrieval. The affirmation of cardiac (...) criteria for death is not an alternative form of essentialism as some critics suppose, but part of an understanding of human life and death which rejects essentialism altogether. The spontaneously persistent heartbeat does not constitute human life, but most certainly counts for it. (shrink)

Should we remove whole organs from living donors only in the case where they are genetically related to the intended recipients of such organs? The practice in a majority of European nations is to apply such a restriction. Yet this restriction obviously limits the availability of already scarce donor organs, and curtails the opportunities for altruistic action on the part of those who, in any given case, are not genetically related to the recipient. The author argues that we have a (...) duty to maximise procurement of organs, and that we should respect the 'genetic relative' restriction only in response to compelling moral reasons. The author considers the principal objections to non-related donation and shows them to be misdirected. He concludes that non-related donation should be welcomed where clinically appropriate and truly voluntary. (shrink)

The experimentally supported existence of the Evans Vigier field.B (3),in vacuo implies that the gravitational and electromagnetic fields can be unified within the same Ricci tensor, being respectively its symmetric and antisymmetric components in vacuo. The fundamental equations of motion of vacuum electromagnetism are developed in this framework.

The classical relativistic theory is developed of electric and magnetic fields in terms of boost and rotation generators, respectively, of the Lorentz group of space-time. This development shows that Minkowski geometry requires that there be threestates of polarization of radiation in free space. The magnetic components in a circular basis are right and left circular and longitudinal. The longitudinal component is real and physical, and proportional to one of the three, nonzero, rotation generators of the Lorentz group. The longitudinal electric (...) component is pure imaginary, and proportional to one of the three boost generators. These theoretical arguments conform with experimental data from the Planck radiation law and from magnetic effects of light such as the inverse Faraday effect. (shrink)

Towards a Poetics of Light; The Conceits of Light is a critical quest to map associations between rhetorical figures, psychological defences and spatial tropes in an attempt to conceive a poetic design that enacts conceit. Light is an emblem which echoes with an abundance of representations in literature, history, art and architecture and parallels may be drawn between their resemblances however apparently remote. Love, knowledge, hope and creative passion mark turns in the threads that knot ideas and their representations together. (...) Return of the Immortals, the final project in a series of works exploring these parallels and representations, gathers together a cascade of tropes to structure a spatial experience which culminates in The Conceits of Light.

The existence of the longitudinal field B (3) in the vacuum implies that the gauge group of electrodynamics is O(3),and not U(1) [or O(2)].This results directly in the charge quantization condition e=h(ϰ/A (0)).This condition is derived independently in this paper from the relativistic motion of one electron in the field and is shown to he that in which the electron travels infinitesimally close to the speed of light.

The relation is developed between rotation generators of the Lorentz group and the magnetic fields of free-space electromagnetism. Using these classical relations, it is shown that in the quantum field theory there exists a longitudinal photomagneton, a quantized magnetic flux density operator which is directly proportional to the photon spin angular momentum. Commutation relations are given in the quantum field between the longitudinal photomagneton and the usual transverse magnetic components of quantized electromagnetism. The longitudinal component is phase free, but the (...) transverse components are phase dependent. All three components can magnetize material in general, but only the transverse components contribute to Planck's law. The photon therefore has three, not two, relativistically invariant degrees of polarization, an axial, longitudinal, polarization, and the usual right and left circular transverse polarizations. Since the longitudinal polarization is axial, it is a phase- free magnetic field. (shrink)

Using covariant derivatives and the operator definitions of quantum mechanics, gauge invariant Proca and Lehnert equations are derived and the Lorenz condition is eliminated in U(1) invariant electrodynamics. It is shown that the structure of the gauge invariant Lehnert equation is the same in an O(3) invariant theory of electrodynamics.

The role of the novel longitudinal vacuum fieldB (3)is discussed in relation to fundamental radiation laws: the Rayleigh-Jeans law, the Planck law, and the Einstein coefficients. The circular index (3) ofB (3)causes electromagnetic energy density to be redistributed from the other indices (1) and (2) of the circular basis, but the presence ofB (3)in the vacuum does not change the value of the Planck constant h. TheB (3)field does not affect, furthermore, the understanding of quantized radiation absorption first proposed by (...) Einstein. Therefore, the experimental observableB (3) does not imply modification of these fundamental, radiation laws, and experimental isolation ofB (3) must take place through its characteristic square root power density dependence when used to magnetize an électron plasma.
