The cholinergic system is a good candidate for the role of determining the relative weight given in cortical information processing to new sensory information versus prior knowledge. We discuss the physiological data supporting this, and suggest that this Bayesian perspective can easily be reconciled with the dynamical framework proposed by Behrendt & Young.
BackgroundPrenatal and early postnatal choline supplementation reduces cognitive and behavioral deficits in animal models of Fetal Alcohol Spectrum Disorder. In a previously published 9-month clinical trial of choline supplementation in children with FASD, we reported that postnatal choline was associated with improved performance on a hippocampal-dependent recognition memory task. The current paper describes the neurophysiological correlates of that memory performance for trial completers.MethodsChildren with FASD who were enrolled in a clinical trial of choline supplementation were followed for 9 months. Delayed (...) recall on a 9-step elicited imitation task served as the behavioral measure of recognition memory. Neurophysiological correlates of memory were assessed via event-related potentials.ResultsDelayed recall on EI was correlated with two ERP components commonly associated with recognition memory in young children: middle latency negative component and positive slow wave. No significant ERP differences were observed between the choline and placebo groups at the conclusion of the trial.ConclusionAlthough the small sample size limits the ability to draw clear conclusions about the treatment effect of choline on ERP, the results suggest a relationship between memory performance and underlying neurophysiological status in FASD. This trial was registered.1. (shrink)
A woman’s lack of or limited reproductive autonomy could lead to adverse health effects, feeling of being inferior, and above all being unable to adequately care for her children. Little is known about the reproductive autonomy of married Ikwerre women of Rivers State, Nigeria. This study demonstrates how Ikwerre women understand the terms autonomy and reproductive rights and what affects the exercise of these rights. An exploratory research design was employed for this study. A semi-structured interview schedule was used to (...) conduct thirty-four in-depth interviews and six focus group discussions with purposively sampled educated, semi-educated, and uneducated Ikwerre women in monogamous or polygynous marriages. The collected data was analysed qualitatively with MAXQDA 11 using open and axial coding. The interviews and focus group responses reveal a low level of awareness of autonomy and reproductive rights amongst the Ikwerre women in Nigeria. While some educated women were aware of their reproductive rights, cultural practices were reported to limit the exercise of these rights. Participants reported that Ikwerre culture is a patriarchal one where married women are expected to submit and obey their husbands in all matters; and a good married woman according to Ikwerre standard is one who complies with this culture. Women’s refusal of sexual advances from their husbands is described as not being acceptable in this culture; and hence rape in marriage is not recognized in Ikwerre culture. Education and awareness creation on the importance of women’s reproductive autonomy could improve their reproductive rights and autonomy in marital settings. Overcoming the patriarchal aspects of Ikwerre culture—for example, the greater value placed on male children than female children and treating women as incompetent individuals—is necessary to promote gender equality as well as help improve women’s reproductive autonomy.

This volume addresses a wide variety of moral concerns regarding slavery as an institutionalized social practice. By considering the slave's critical appropriation of the natural rights doctrine, the ambiguous implications of various notions of consent and liberty are examined. The authors assume that, although slavery is undoubtedly an evil social practice, its moral assessment stands in need of a more nuanced treatment. They address the question of what is wrong with slavery by critically examining, and in some cases endorsing, certain (...) principles derived from communitarianism, paternalism, utilitarianism, and jurisprudence.

Three studies were conducted to explore the psychological determinants of COVID-deterrent behaviors. In Study 1, using data collected and analyzed both before and after the release of COVID-19 vaccines, mask-wearing, other preventative behaviors like social distancing, and vaccination intentions were positively related to assessments of the Coronavirus Behavioral Health Mindset ; belief in the credibility of science; progressive political orientation; less use of repressive and more use of sensitization coping; and the attribution of COVID-19 safety to effort rather than ability, (...) powerful forces, fate, or luck. In Study 2, favorable COVID-19 vaccination intentions were related to greater willingness to work, lower emotional distress, and greater customer experience mindset. Study 3 examined the personality and motives of individuals who volunteered to help deliver COVID-19 inoculations to the local community. The vaccine-giving volunteers, especially those with prosocial motives, had high CVBHM scores, belief in the credibility of science, low use of repressive coping, greater attribution of COVID-19 protection to effort, low likelihood of voting conservative, were older, and had more education than others. The majority of public health volunteers expressed prosocial motives to help people or join a cause, but many expressed the personal motives of getting the COVID-19 vaccination for themselves, conveying a public image of compassion, or structuring time. Based on the three research studies, a COVID-19 Mindset Hierarchy model is proposed to integrate the results. (shrink)
Informed by understandings of affect theory, the pedagogic potential of object itineraries, or simply, the journey of things, is proposed in this case as a form of sensual a-r-tography. A pair of sporty shoes as mundane objects are at the heart of this deliberation, and the mechanism through which to consider the scope of conversations underway about more-than-human perspectives and how objects can be activated as sites of educational inquiry. The embodiment of each step in this walk is an opening (...) to interrogate how the potential materiality of artefacts ‘enflesh’ object-body-space as artist-researcher-teacher. Mapping geographies of self-in-relation, and guided by the betweenness in landscape encounters as relational and contingent, this speculative account with theoretical perspectives is rendered through the entanglements offered by story shoes.

Although clinical ethics consultation is a high-stakes endeavor with an increasing prominence in health care systems, progress in developing standards for quality is challenging. In this article, we describe the results of a pilot project utilizing portfolios as an evaluation tool. We found that this approach is feasible and resulted in a reasonably wide distribution of scores among the 23 submitted portfolios that we evaluated. We discuss limitations and implications of these results, and suggest that this is a significant step (...) on the pathway to an eventual certification process for clinical ethics consultants.

We explore the nature of forgetting in a corpus of 125,000 students learning Spanish using the Rosetta Stone® foreign-language instruction software across 48 lessons. Students are tested on a lesson after its initial study and are then retested after a variable time lag. We observe forgetting consistent with power function decay at a rate that varies across lessons but not across students. We find that lessons which are better learned initially are forgotten more slowly, a correlation which likely reflects a (...) latent cause such as the quality or difficulty of the lesson. We obtain improved predictive accuracy of the forgetting model by augmenting it with features that encode characteristics of a student's initial study of the lesson and the activities the student engaged in between the initial and delayed tests. The augmented model can predict 23.9% of the variance in an individual's score on the delayed test. We analyze which features best explain individual performance. (shrink)
The essays in this volume present versions of feminism that are explicitly liberal, or versions of liberalism that are explicitly feminist. By bringing together some of the most respected and well-known scholars in mainstream political philosophy today, Amy R. Baehr challenges the reader to reconsider the dominant view that liberalism and feminism are 'incompatible.'.
The shapes of neurons and glial cells dictate many important aspects of their functions. In olfactory systems, certain architectural features are characteristics of these two cell types across a wide variety of species. The accumulated evidence suggests that these common features may play fundamental roles in olfactoryinformation processing. For instance, the primary olfactory neuropil in most vertebrate and invertebrate olfactory systems is organized into discrete modules called glomeruli. Inside each glomerulus, sensory axons and CNS neurons branch and synapse in patterns (...) that are repeated across species. In many species, moreover, the glomeruli are enveloped by a thin and ordered layer of glial processes. Theglomerular arrangement reflects the processing of odor information in modules that encode the discrete molecular attributes of odorant stimuli being processed. Recent studies of the mechanisms that guide the development of olfactory neurons and glial cells have revealed complex reciprocal interactions between these two cell types, which may be necessary for the establishment of modular compartments. Collectively, the findings reviewed here suggest that specialized cellular architecture plays key functional roles in the detection, analysis, and discrimination of odors at early steps in olfactory processing.

Multiple groups, including the National Bioethics Advisory Commission, the American Society of Clinical Oncology, the National Coalition of Comprehensive Cancer Centers, Workgroup 6 of the Summit Series on Cancer, PRIM&R, the Bell Report, and prominent ethicists have called for replacing the current system of local institutional review with central review for multisite national trials. We argue that this need is particularly acute in pediatric oncology, as shown by the experience of the Children's Oncology Group.
Rossbank functioned from 1840 to 1854 as one of a chain of British Colonial Observatories which combined with European and Asian observatories in the study of terrestrial magnetism. It was established in Hobart, Tasmania, by the Governor of Van Diemen's Land, Sir John Franklin, and Captain James Clark Ross, R.N., commanding H.M. ships Erebus and Terror. The history and operation of the Rossbank Observatory is related, its instruments described, and the results discussed.Biographical notes on the Observatory staff, with lists of (...) its archives and instruments are provided. A number of previously unpublished pictures show the Observatory in use and the surviving buildings and instruments today. (shrink)
