Because of the nature of preventive vaccination programs, the viability of these public health interventions is particularly susceptible to public perceptions. This is because vaccination relies on a concept of ‘herd immunity’, achievement of which requires rational public behavior that can only be obtained through full and accurate communication about risks and benefits. This paper describes how irrational behavior that threatens the effectiveness of vaccination programs – both in crisis and non-crisis situations – can be tied to public perceptions created (...) by media portrayals of health risks. I concentrate on childhood vaccination as an exemplar of ‘non-crisis’ preventive vaccination, and on the recent flu vaccine shortage as a ‘crisis’ situation. The paper concludes with an examination of the steps necessary to resolve these threats through better public communication. (shrink)

The spinal cord provides an alternative model for nerve tissue grafting experiments. Anatomo-functional correlations are easier to make here than in any other region of the CNS because of a direct implication of spinal cord neurons in sensorimotor activities. Lesions can be easily performed to isolate spinal cord neurons from descending inputs. The anatomy of descending monoaminergic systems is well defined and these systems offer a favourable paradigm for lesion-graft experiments.

This paper discusses the possibility of creating a digital platform based on Mojo v3 for monitoring the operation of a dual-circuit solar collector. In the proposed system, measurements are made from 6 digital sensors, 16 wires are used. Using Dallas sensors and the appropriate software, you can monitor the temperature level and the amount of heat. The use of 6 digital sensors significantly increases the efficiency of control over the system and increases the speed of data processing. The possibilities of (...) configuring sensors for the platform Mojo v3, as well as the control circuit of the solar collector are considered. (shrink)

Taking up Kimberlé Crenshaw's conclusion that black feminist theorists seem to continue to find themselves in many ways “speaking into the void” (Crenshaw 2011, 228), even as their works are widely celebrated, I examine intersectionality critiques as one site where power asymmetries and dominant imaginaries converge in the act of interpretation (or cooptation) of intersectionality. That is, despite its current “status,” intersectionality also faces epistemic intransigence in the ways in which it is read and applied. My aim is not to (...) suggest that intersectionality cannot (or should not) be critiqued, nor do I maintain that celebratory applications/interpretations are immune from epistemic distortion when it comes to interpreting intersectionality. Rather, my goal is to demonstrate that critiques of intersectionality are one important site to examine hermeneutic marginalization and interpretive violence; the politics of citation; and the impact of dominant expectations or established social imaginaries on meaning-making. In so doing, I aim to consider more fully how entrenched ways of thinking are frequently relied upon to interpret and critique intersectionality, even as these are often the very frameworks that intersectionality theorists have identified as highly problematic tools of misrepresentation, erasure, and violation. This slippage away from intersectionality's outlooks, whether in critical or laudatory contexts, is a pivotal site of epistemic negotiation we must examine more closely. (shrink)

The considerable attention to financial interests in clinical research has focused mostly on academic medical centers, even though the majority of clinical research is conducted in community practice settings. To fill this gap, this article maps the practices and policies in 73 community hospitals and several hundred specialized facilities around the country for reviewing clinical investigators’ financial relationships with research sponsors. Community hospitals face a substantially different mix of issues than academic medical centers do because their physician researchers are usually (...) not employees, and more of their studies are later-phase, multicenter trials. Accordingly, community physicians stand to benefit personally from per capita payments, but they tend to have less direct influence over research findings when compared with their academic peers. These and other contrasts require separate guidance for community-based organizations that takes into account their particular needs, circumstances, and institutional capacities. (shrink)

Anna Julia Cooper's 1892 A Voice from the South is a hybrid text that speaks provocatively to contemporary feminist philosophy. Negotiating exclusionary categories of being and knowing and writing herself into intellectual traditions meant to exclude her, Cooper's narrative methods are politically tactical and epistemologically significant. Cooper inserts subjectivity into objective analysis and underscores knowledge as located and embodied. By speaking from spaces of exclusion, Cooper fully articulates the promise of intersectional approaches to liberation.

Objectives: To assess French district nurses’ opinions towards euthanasia and to study factors associated with these opinions, with emphasis on attitudes towards terminal patients.Design and setting: An anonymous telephone survey carried out in 2005 among a national random sample of French district nurses.Participants: District nurses currently delivering home care who have at least 1 year of professional experience. Of 803 district nurses contacted, 602 agreed to participate .Main outcome measures: Opinion towards the legalisation of euthanasia , attitudes towards terminal patients (...) .Results: Overall, 65% of the 602 nurses favoured legalising euthanasia. Regarding associated factors, this proportion was higher among those who discuss end-of-life issues with terminal patients , who consider competent patients should always be told their prognosis and who value the role of advance directives and surrogates in end-of-life decision-making for incompetent patients . Women and older nurses were less likely to favour legalising euthanasia, as were those who believed in a god who masters their destiny.Conclusions: French nurses are more in favour of legalising euthanasia than French physicians; these two populations contrast greatly in the factors associated with this support. Further research is needed to investigate how and to what extent such attitudes may affect nursing practice and emotional well-being in the specific context of end-of-life home care. (shrink)

To flesh out love's potential for transformative imaginaries and politics, it is important to explore earlier examples of Black feminist theorizing on love. In this spirit, I examine Anna Julia Cooper, an early Black feminist educator, intellectual, and activist whose work is generally overlooked in feminist and anti-racist thinking on love, affect, and social change. Contesting narrow readings of Cooper, I first explore how critics might engage in more “loving” approaches to reading her work. I then delineate some of her (...) contributions to a Black feminist love-politics. In unmasking dominance enacted in love's name, Cooper analyzes romantic love, marriage, and gendered care-work in the domestic sphere. Using an intersectional lens, she contests gendered-raced hierarchies and links normative masculinity and femininity with white supremacy, xenophobia, and imperial rule. Cooper also extolls the possibilities of love rooted in nonhierarchical, intersubjective cooperation: such loving has the potential to transform interpersonal relations and foster broad collaborative action to eradicate inequality, locally and globally. Structural subjection, internalized oppression, and colonized imaginations have no part in Cooper's reciprocal, political love-force. Unfortunately, her ideas about transforming gender relations, contesting racism, challenging imperialism, seeking decolonized selves, and pursuing solidarity as a loving political orientation remain relatively unknown.

If a hereditary predisposition to colorectal cancer or breast cancer is diagnosed, most guidelines state that clinical geneticists should request index patients to inform their at-risk relatives about the existence of this condition in their family, thus enabling them to consider presymptomatic genetic testing. Those identified as mutation carriers can undertake strategies to reduce their risk of developing the disease or to facilitate early diagnosis. This procedure of informing relatives through the index patient has been criticised, as it results in (...) relatively few requests for genetic testing, conceivably because a certain number of relatives remain uninformed. This pilot study explored attitudes toward informing family members and relevant practices among clinical geneticists. In general, clinical geneticists consider it to be in the interests of family members to be informed and acknowledge that this goal is not accomplished by current procedures. The reasons given for maintaining present practices despite this include clinical ‘mores’, uncertainty about the legal right of doctors to inform family members themselves, and, importantly, a lack of resources. We discuss these reasons from an ethical point of view and conclude that they are partly uninformed and inconsistent. If informing relatives is considered to be in their best interests, clinical geneticists should consider informing relatives themselves. In the common situation in which index patients do not object to informing relatives, no legal obstacles prevent geneticists from doing so. An evaluation of these findings among professionals may lead to a more active approach in clinical practice. (shrink)

Shani Mootoo's Cereus Blooms at Night demonstrates how willful and strategic epistemologies of ignorance intertwine. By rejecting a compartmentalized approach to domination, Mootoo highlights the disjuncture between idealized images of family, home, love, and the Caribbean and traumatic events of personal and cultural history. Mootoo not only asks readers to take up resistant questioning, argues May, but also to recognize that epistemology must acknowledge unspeakable and silenced stories to adequately account for multiple ways of knowing.

This study used the latent profile transition analysis to analyze whether emotional labor profiles change across time and how these profiles relate to occupational well-being (i.e., job satisfaction, quality of work life, psychological distress, and work–family conflict). A total of 155 full-time Chinese employees completed the questionnaire survey at two time points. Three latent profiles were identified at Time 1 and the same profiles were replicated at Time 2. We determined that the majority of the participants retained the original profiles. (...) Lastly, occupational well-being differed significantly across the identified profiles. The limitations and implications of this study were also provided. (shrink)

Background Paediatric clinical research faces unique challenges that compromise optimal recruitment of children into clinical trials. A main barrier to enrolment of children is parental misconceptions about the research process. In developing countries, there is a knowledge gap regarding parental perceptions of and attitudes towards their children's participation in clinical trials. Objective To explore such perceptions and attitudes in Lebanese parents. Study design 33 in-depth interviews were conducted with parents with and without previous research experience. Interviews were tape-recorded, transcribed in (...) colloquial Arabic, and later subjected to thematic analysis. Results Benefit/risk ratio assessment was a major determinant of parental consent. Fear of adverse events or painful procedures in research was a recurring theme in most interviews. Whereas perception of direct benefit to the child, trust in the physician or institution, financial gains or having a positive previous experience in research facilitated consent, a complex informed consent form and misunderstanding of the term ‘randomisation’ hindered parental approval of participation. Conclusion Lebanese parents have perceptions of and attitudes towards children's participation in clinical trials that are similar to those reported from the industrialised world. Improving communication with parents and building trust between researchers and parents is important for successful recruitment. Investigators planning to conduct paediatric trials in developing countries need to simplify consent forms and devise new ways to explain randomisation. (shrink)

The present study investigates procedural learning of motor sequences in children with developmental coordination disorder and/or developmental dyslexia, typically-developing children and healthy adults with a special emphasis on the role of the nature of stimuli and the neuropsychological functions associated to final performance of the sequence. Seventy children and ten adults participated in this study and were separated in five experimental groups: TD, DCD, DD, and DCD + DD children and adults. Procedural learning was assessed with a serial reaction time (...) task that required to tap on a specific key as accurately and quickly as possible when stimuli appeared on the screen. Three types of stimuli were proposed as cues: the classical version of the SRTT with 4 squares aligned horizontally on the screen, giving visuospatial cues, and two modified versions, with 4 letters aligned horizontally on the screen and letters at the center of the screen. Reaction times during the repeated and random blocks allowed assessing three phases of learning: global learning, specific learning and retention of the sequence. Learning was considered as completed when RT evolved significantly in the three phases. Neuropsychological assessment involved, among other functions, memory and attentional functions. Our main result was that learning and retention were not influenced by the available cues in adults whereas learning improved with specific cues in children with or without neurodevelopmental disorders. More precisely, learning was not completed with L cues in children with neurodevelopmental disorders. For children with DD, learning was completed with the VS and VS + L cues whereas for children with DCD, learning was completed with combined VS + L cues. Comorbidity between DD and DCD had no more impact on procedural learning than DCD alone. These results suggest that learning depends on the nature of cues available during practice and that cues allowing learning and retention depend on the type of disorder. Moreover, selective attention was correlated with RT during retention, suggesting that this neuropsychological function is important for procedural learning whatever the available cues. (shrink)

A summary of the career of a Russian engineer who practiced a century ago in western Europe, as well as in Russia, provides an example of how ethical standards can influence practice across national boundaries. An examination of his career and his conception of engineering, of the evolution of engineering standards and codes, and of the process of formulating codes in particular instances explains how international standards can shape practice in an international context.

A method is presented to compute the electron-optical phase shift for a magnetized polyhedral nanoparticle, with either a uniform magnetization or a closure domain . The method relies on an analytical expression for the shape amplitude, combined with a reciprocal-space description of the magnetic vector potential. The model is used to construct two building blocks from which more complex structures can be generated. Phase computations are also presented for the five Platonic and 13 Archimedean solids. Fresnel and Foucault imaging mode (...) simulations are presented for a range of particle shapes and microscope imaging conditions. (shrink)
