Anterior cingulate cortex {ACC} is a part of the brain's limbic system. Classically, this region has been related to affect, on the basis of lession studies in human and in animals. In the late 1980s, neuroimaging research indicated that ACC was active in many studies of cognition. The finding from EEG studies of a focal area of negativity in scalp electrodes following an error response led to the idea that ACC might be the brain's error detection and correction device.

Accessing BRCA1/2 data facilitates the detection of disease-associated variants, which is critical to informing clinical management of risks. BRCA1/2 data sharing is complex and many practices exist. We describe current BRCA1/2 data-sharing practices, in the United States and globally, and discuss obstacles and incentives to sharing, based on 28 interviews with personnel at U.S. and non-U.S. clinical laboratories and databases. Our examination of the BRCA1/2 data-sharing landscape demonstrates strong support for and robust sharing of BRCA1/2 data around the world, increasing (...) global accesses to diverse data sets.

A 2011 National Academies of Sciences report called for an “Information Commons” and a “Knowledge Network” to revolutionize biomedical research and clinical care. We interviewed 41 expert stakeholders to examine governance, access, data collection, and privacy in the context of a medical information commons. Stakeholders' attitudes about MICs align with the NAS vision of an Information Commons; however, differences of opinion regarding clinical use and access warrant further research to explore policy and technological solutions.

The Chacoan road system is an understudied aspect of a very unique culture in New Mexico. The extensive roads present important evidence to the social structure of the Chaco people. A few theories have been presented about the reason for the roads, such as economic, administrative and religion. This paper argues that the roads were used for military purposes, because the roads provided quick access to all satellite townships in the region.

As a direct consequence of the sophisticated arrangement of its intrinsic neurons, the gastrointestinal tract is unique among peripheral organs, in its ability to mediate its own reflexes. Neurons of the enteric nervous system are intimately associated with enteric glial cells. These supporting cells do not resemble Schwann cells, the glial cell found in all other parts of the peripheral nervous system, but share many similarities with astrocytes of the central nervous system. Ablation of enteric glial cells in adult transgenic (...) mice has demonstrated that these cells are essential to maintain the integrity of the small intestine. Acute loss of enteric glial cells induces massive pathological changes with similarities to necrotizing enterocolitis (NEC) and early Crohn's disease. These human conditions share some mechanistic similarities. Identification of enteric glial cell dysfunction/loss as sufficient to induce necrotic/inflammatory bowel disease may be important to understand the pathogenesis of both NEC and Crohn's disease.

Meaningful participant engagement has been identified as a key contributor to the success of efforts to share data via a “Medical Information Commons”. We present findings from expert stakeholder interviews aimed at understanding barriers to engagement and the appropriate role of MIC participants. Although most interviewees supported engagement, they distinguished between individual versus collective forms. They also noted challenges including representation and perceived inefficiency, prompting reflection on political aspects of engagement and efficiency concerns.

Conflicts of interest affect recommendations in clinical guidelines and disclosure of such conflicts is important. However, not all conflicts of interest are disclosed. Using a public available disclosure list we determined the prevalence and underreporting of conflicts of interest among authors of clinical guidelines on drug treatments.

Medical aid in dying (MAiD), despite being legal in many jurisdictions, remains controversial ethically. Existing surveys of physicians’ perceptions of MAiD tend to focus on the legal or moral permissibility of MAiD in general. Using a novel sampling strategy, we surveyed physicians likely to have engaged in MAiD-related activities in Colorado to assess their attitudes toward contemporary ethical issues in MAiD.

A recent study using a crossmodal matching task showed that the identity of a talker could be recognized even when the auditory and visual stimuli that were being matched were different sentences spoken by the talker. This finding implies that general temporal features of a person's speech are shared across the auditory and visual modalities.

Following Karni's seminal work, Walker and other researchers have recently provided gradually convincing evidence that sleep is critical for the consolidation-based enhancement (CBE) of motor sequence learning. Studies in our laboratory using a motor adaptation paradigm, however, show that CBE can also occur after the simple passage of time, suggesting that sleep effects on memory consolidation are task-related, and possibly dependent on anatomically dissociable circuits.

Drawing on a landscape analysis of existing data-sharing initiatives, in-depth interviews with expert stakeholders, and public deliberations with community advisory panels across the U.S., we describe features of the evolving medical information commons. We identify participant-centricity and trustworthiness as the most important features of an MIC and discuss the implications for those seeking to create a sustainable, useful, and widely available collection of linked resources for research and other purposes.

This book's importance is derived from three sources: careful conceptualization of teacher induction from historical, methodological, and international perspectives; systematic reviews of research literature relevant to various aspects of teacher induction including its social, cultural, and political contexts, program components and forms, and the range of its effects; substantial empirical studies on the important issues of teacher induction with different kinds of methodologies that exemplify future directions and approaches to the research in teacher induction.

Background This paper describes the design, implementation, and process outcomes from three public deliberations held in three tribal communities. Although increasingly used around the globe to address collective challenges, our study is among the first to adapt public deliberation for use with exclusively Indigenous populations. In question was how to design deliberations for tribal communities and whether this adapted model would achieve key deliberative goals and be well received.Methods We adapted democratic deliberation, an approach to stakeholder engagement, for use with (...) three tribal communities to respect tribal values and customs. Public deliberation convenes people from diverse backgrounds in reasoned reflection and dialogue in search of collective solutions. The deliberation planning process and design were informed by frameworks of enclave deliberation and community-based participatory research, which share key egalitarian values. The deliberations were collaboratively designed with tribal leadership and extensive partner input and involvement in the deliberations. Each deliberation posed different, locally relevant questions about genomic research, but used the same deliberation structure and measures to gauge the quality and experience of deliberation.Results A total of 52 individuals participated in the deliberations across all three sites. Deliberants were balanced in gender, spanned decades in age, and were diverse in educational attainment and exposure to health research. Overall, the deliberations were positively evaluated. Participant perceptions and external observer datasets depict three deliberations that offered intensive conversation experiences in which participants learned from one another, reported feeling respected and connected to one another, and endorsed this intensive form of engagement.Conclusion The adapted deliberations achieved key deliberative goals and were generally well received. Limitations of the study are described. (shrink)

Researchers from diverse disciplines, including organismal and cellular physiology, sports science, human nutrition, evolution and ecology, have sought to understand the causes and consequences of the surprising variation in metabolic rate found among and within individual animals of the same species. Research in this area has been hampered by differences in approach, terminology and methodology, and the context in which measurements are made. Recent advances provide important opportunities to identify and address the key questions in the field. By bringing together (...) researchers from different areas of biology and biomedicine, we describe and evaluate these developments and the insights they could yield, highlighting the need for more standardisation across disciplines. We conclude with a list of important questions that can now be addressed by developing a common conceptual and methodological toolkit for studies on metabolic variation in animals. (shrink)

More than 200 million children under the age of 5 years are affected by malnutrition worldwide according to the World Health Organization. The Barbados Nutrition Study (BNS) is a 55-year longitudinal study on a Barbadian cohort with histories of moderate to severe protein-energy malnutrition (PEM) limited to the first year of life and a healthy comparison group. Using quantitative electroencephalography (EEG), differences in brain function duringchildhood(lower alpha1 activity and higher theta, alpha2 and beta activity) have previously been highlighted between participants (...) who suffered from early PEM and controls. In order to determine whether similar differences persisted intoadulthood, our current study used recordings obtained during a Go-No-Go task in a subsample of the original BNS cohort [population size (N) = 53] at ages 45–51 years. We found that previously malnourished adults [sample size (n) = 24] had a higher rate of omission errors on the task relative to controls (n= 29). Evoked-Related Potentials (ERP) were significantly different in participants with histories of early PEM, who presented with lower N2 amplitudes. These findings are typically associated with impaired conflict monitoring and/or attention deficits and may therefore be linked to the attentional and executive function deficits that have been previously reported in this cohort in childhood and again in middle adulthood.

The article makes four interrelated claims: (1) The mechanism approach to social explanation does not presuppose a commitment to the individual-level microfoundationalism. (2) The microfoundationalist requirement that explanatory social mechanisms should always consists of interacting individuals has given rise to problematic methodological biases in social research. (3) It is possible to specify a number of plausible candidates for social macro-mechanisms where interacting collective agents (e.g. formal organizations) form the core actors. (4) The distributed cognition perspective combined with organization studies could (...) provide us with explanatory understanding of the emergent cognitive capacities of collective agents. (shrink)

Ethics instructors often use cases to help students understand ethics within a corporate context, but we need to know more about the impact a case-based pedagogy has on students’ ability to make ethical decisions. We used a pre- and post-test methodology to assess the effect of using cases to teach ethics in a finance course. We also wanted to determine whether recent corporate ethics scandals might have impacted students’ perceptions of the importance and prevalence of ethics in business, so we (...) used in-depth case studies of several of the major scandals (e.g., Enron, Tyco, Adelphia). Our results are somewhat surprising since studying ethics scandals positively impacts students’ ethical decision making and their perceptions of the ethics of businesspeople. (shrink)

In Re G, the Court of Appeal awarded a joint residence order to the appellant, who was the lesbian ex-partner of the child’s full biological mother. The award also indirectly vested the appellant, a social parent, with parental responsibility and extended a body of case law to same-sex couples, which had until now only been applied to heterosexual couples. The initial purpose of this note is to outline the legal issues of the case in the context of the framework of (...) parental responsibility set out in the Children Act 1989, putting forward a test of ‘parental fitness’ (which focuses on active ‘care’ as its central consideration) for social parents who must appeal to the court’s discretion to obtain parental responsibility. Secondly, the note offers at once a positive reading of Re G while highlighting a number of reservations centring upon continued legal preference for the ‘sexual family’. It is argued that while the legal recognition of ‘family diversity’ and parenthood remains modelled on this ‘sexual family’, the relaxation of family ‘boundaries’ (despite legal victories such as Re G) will remain limited.

In Against Absolute Goodness Richard Kraut aims to show that absolute goodness (or badness) is not reason-giving; it plays no role is justifying or requiring certain attitudes and no role in reasoning about what to do. It passes the buck (it never adds to the weightiness of more specific reasons) and so for practical purposes can be ignored. However, he claims that the notions of ‘a good R’ (e.g. a good play) and ‘good for S’ do justify certain attitudes and (...) play important roles in practical reasoning and do not pass the buck. In this review I critique Kraut’s argument that the notions of ‘a good R’ (e.g. a good play) and ‘good for S’ differ from absolute goodness in these ways. Moreover, I discuss and defend Aristotle’s notion of ‘the fine’ or ‘noble’ (καλόν) and Kant’s notion of unconditional goodness. (shrink)

We present four new change detection methods that create an automated change map from a probability map. In this case, the probability map was derived from a 3D model. The primary application of interest is aerial photographic applications, where the appearance, disappearance or change in position of small objects of a selectable class (e.g., cars) must be detected at a high success rate in spite of variations in magnification, lighting and background across the image. The methods rely on an earlier (...) derivation of a probability map. We describe the theory of the four methods, namely Bernoulli variables, Markov Random Fields, connected change, and relaxation-based segmentation, evaluate and compare their performance experimentally on a set probability maps derived from aerial photographs.

The aim of this chapter is to identify the most representative measures of subjective and objective mental workload in driving, and to understand how the subjective and objective levels of mental workload influence the performance as a function of situation complexity and driving experience, i.e. to verify whether the increase of situation complexity and the lack of experience increase the subjective and physiological levels of mental workload and lead to driving performance impairments. This chapter will be useful to carry out (...) an experimental study and to improve the driver training. In the first part, we will broach the theoretical approach with two factors of mental workload and performance, i.e. situation complexity and driving experience. Indeed, a low complex situation (e.g., highways), or conversely a high complex situation (e.g., town) can provoke an overload. Additionally, performing the driving tasks implies producing a high effort for novice drivers who have not totally automated the driving activity. In the second part, we will focus on subjective measures of mental workload. A comparison of questionnaires usually used in driving will allow identifying the most appropriate ones as a function of different criteria. Moreover, we will review the empirical studies to verify if the subjective level of mental workload is high in simple and very complex situations, especially for novice drivers compared to the experienced ones. In the third part, we will focus on physiological measures. A comparison of physiological indicators will be realized in order to identify the most correlated to mental workload. An empirical review will also take the effect of situation complexity and experience on these physiological indicators into consideration. Finally, a more nuanced comparison between subjective and physiological measures will be established from the impact on situation complexity and experience. (shrink)

The neuro-enhancement Modafinil promises to dramatically increase users' waking hours without much sacrifice to clarity of thought and without serious side effects (inducing addiction). For Modafinil to be advantageous, its usage must enable access to goods that themselves improve the quality of one's life. I draw attention to a variety of conditions that must be met for an experience, activity or object to improve the quality of one's life, such as positional, relational, and saturation conditions, as well as it's being (...) good for its own sake. I discuss and describe the contexts in which widespread usage (legal or not) of Modafinil would undermine these conditions being met, and thus users would fail to significantly improve the quality of their lives and would in fact potentially make both themselves and nonusers worse off in important respects thus far overlooked by critics. In the right contexts, where free time is protected and prolonged, Modafinil does have a variety of potential benefits including, most interestingly, a distinctive form of agency possible only in free time. The potential disadvantages and advantages highlighted in this article are relevant not only to public institutions deciding whether to legalize Modafinil's use as an enhancement but also to individuals deciding whether to use it illegally, as well as to the questions of how and whether to alter key features of one's context (e.g. regulating work hours or extending social services) rather than, or in addition, to regulating the use of enhancement drugs such as Modafinil.

Seemingly distant practices of molecular biology and indigenous Xhosa healing have commonalities that I would like to bring into conversation in this article. The preclinical trial of an indigenous medicine brings them together in a research consortium. In this instance, both sets of experts are meant to collaborate in preparing a wild bush for it to pass the tests of the randomized clinical trial (RCT) and to potentially become a biopharmaceutical to counter the tuberculosis pandemic. I aim to tease (...) out how the two sets of actors and their respective practices converge and diverge in their healing hopes and ways of managing uncertainty. Ultimately, I am interested in understanding how the preferred process of making medicine “work” by each set of actors relies upon particular ways of knowing and not knowing life, bringing some ontologies into being, letting others wither away. The shared ways of knowing life as a movement of opening at the edges of the RCT are proposed as paths of recognition between one and the other practice. (shrink)

Although bedbug infestation is not a new public health problem, it is one that is becoming more alarming among healthcare professionals, public health officials, and ethicists given the magnitude of patients who may be denied treatment, or who are unable to access treatment, especially those underserved populations living in low income housing. Efforts to quarantine and eradicate Cimicidae have been and should be made, but such efforts require costly interventions. The alternative, however, can further exacerbate the already growing problems of (...) injustice, i.e., unfair treatment of patients, inaccessibility of needed resources. In the following paper, I examine the ramifications of denying access to medical care, among other healthcare justice dilemmas surrounding bedbug infestations. I also explore the value of health, and how healthcare professionals and public officials often feel as though bedbugs are not a priority because they, themselves, are not diseases, regardless of the fact they cause physical and mental problems that affect a person’s health. I propose recommendations for improving the health and well-being of those vulnerable populations who are facing a difficult and growing public health problem that is currently being ignored in medical and public health ethics literature, regardless of increased media attention and unusual habitats of localized infestations, e.g., Statue of Liberty, New York City.
