Why do black families own less than white families? Why does school segregation persist decades after Brown v. Board of Education? Why is it harder for black adults to vote than for white adults? Will addressing economic inequality solve racial and gender inequality as well? This book answers all of these questions and more by revealing the hidden rules of race that create barriers to inclusion today. While many Americans are familiar with the histories of slavery and Jim Crow, we (...) often don't understand how the rules of those eras undergird today's economy, reproducing the same racial inequities 150 years after the end of slavery and 50 years after the banning of Jim Crow segregation laws. This book shows how the fight for racial equity has been one of progress and retrenchment, a constant push and pull for inclusion over exclusion. By understanding how our economic and racial rules work together, we can write better rules to finally address inequality in America. (shrink)

A response to comments by William Casebeer, Peter Railton, and Michael Ruse on "Naturalizing Ethics" (2007).

There are two broad approaches to environmental ethics. The “conservationist” approach on which we should conserve the environment when it is in our interest to do so and the “preservationist” approach on which we should preserve the environment even when it is not in our interest to do so. We propose a new “relational” approach that tells us to preserve nature as part of what makes us who we are or could be. Drawing from Confucian and Daoist texts, we argue (...) that human identities are, or should be, so intimately tied to nature that human interests evolve in relationship to nature. (shrink)

A central characteristic of people with Prader-Willi Syndrome (PWS) is an apparent insatiable appetite leading to severe overeating and the potential for marked obesity and associated serious health problems and premature death. This behaviour may be due to the effects of the genetic defect resulting from the chromosome 15 abnormalities associated with the syndrome. We examine the ethical and legal dilemmas that can arise in the care of people with PWS. A tension exists between a genetic deterministic perspective and that (...) of individual choice. We conclude that the determination of the capacity of a person with PWS to make decisions about his/her eating behaviour and to control that behaviour is of particular importance in resolving this dilemma. If the person is found to lack capacity, the common law principles of acting in a person's "best interests" using the "least restrictive alternative" may be helpful. Allowing serious weight gain in the absence of careful consideration of these issues is an abdication of responsibility. (shrink)

The COVID-19 pandemic has presented a global threat to physical and mental health worldwide. Research has highlighted adverse impacts of COVID-19 on wellbeing but has yet to offer insights as to how wellbeing may be protected. Inspired by developments in wellbeing science and guided by our own theoretical framework, we examined the role of various potentially protective factors in a sample of 138 participants from the United Kingdom. Protective factors included physical activity, tragic optimism, gratitude, social support, and nature connectedness. (...) Initial analysis involved the application of one-sample t-tests, which confirmed that wellbeing in the current sample was significantly lower compared to previous samples. Protective factors were observed to account for up to 50% of variance in wellbeing in a hierarchical linear regression that controlled for a range of sociostructural factors including age, gender, and subjective social status, which impact on wellbeing but lie beyond individual control. Gratitude and tragic optimism emerged as significant contributors to the model. Our results identify key psychological attributes that may be harnessed through various positive psychology strategies to mitigate the adverse impacts of hardship and suffering, consistent with an existential positive psychology of suffering.

Lexical alignment, a communication phenomenon where conversational partners adapt their word choices to become more similar, plays an important role in the development of language and social communication skills. While this has been studied extensively in the conversations of preschool‐aged children and their parents in Western, Educated, Industrialized, Rich, and Democratic (WEIRD) communities, research in other pediatric populations is sparse. This study makes significant expansions on the existing literature by focusing on alignment in naturalistic conversations of school‐aged children from a (...) non‐WEIRD population across multiple conversational tasks and with different types of adult partners. Typically developing children aged 5 to 8 years (n = 45) engaged in four semi‐structured conversations that differed by task (problem‐solving vs. play‐based) and by partner (parent vs. university student), resulting in a corpus of 180 conversations. Lexical alignment scores were calculated and compared to sham conversations, representing alignment occurring at the level of chance. Both children and adults coordinated their conversational utterances by re‐using or aligning each other's word choices. This alignment behavior persisted across conversational tasks and partners, although the degree of alignment was moderated by the conversational context. These findings suggest that lexical alignment is a robust phenomenon in conversations between school‐age children and adults. Furthermore, this study extends lexical alignment findings to a non‐WEIRD culture, suggesting that alignment may be a coordination strategy employed by adults and children across diverse linguistic and cultural backgrounds.

The practice of covertly administering medication is controversial. Although condemned by some as overly paternalistic, others have suggested that it may be acceptable if patients have permanent mental incapacity and refuse needed treatment. Ethical, legal, and clinical considerations become more complex when the mental incapacity is temporary and when the medication actually serves to restore autonomy. We discuss these issues in the context of a young man with schizophrenia. His mother had been giving him antipsychotic medication covertly in his soup. (...) Should the doctor continue to provide a prescription, thus allowing this to continue? We discuss this case based on the “four principles” ethical framework, addressing the conflict between autonomy and beneficence/non-maleficence, the role of antipsychotics as an autonomy restoring agent, truth telling and the balance between individual versus family autonomy.

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.

With advances in genetic technology, there are increasing concerns about the way in which genetic information may be abused, particularly in people at increased genetic risk of developing certain disorders. In a recent case in Hong Kong, the court ruled that it was unlawful for the civil service to discriminate in employment, for the sake of public safety, against people with a family history of mental illness. The plaintiffs showed no signs of any mental health problems and no genetic testing (...) was performed. This was the first case concerning genetic discrimination in common law jurisdictions, therefore the court's judgment has implications for how genetic discrimination cases may be considered in the future. The court considered it inappropriate to apply population statistics or lifetime risks to individuals while examining fitness for work. It recommended an individualised assessment of specific risks within the job, relative to other risks posed by that workplace. (shrink)

Cultural safety is a relatively new concept that has emerged in the New Zealand nursing context and is being taken up in various ways in Canadian health care discourses. Our research team has been exploring the relevance of cultural safety in the Canadian context, most recently in relation to a knowledge-translation study conducted with nurses practising in a large tertiary hospital. We were drawn to using cultural safety because we conceptualized it as being compatible with critical theoretical perspectives that foster (...) a focus on power imbalances and inequitable social relationships in health care; the interrelated problems of culturalism and racialization; and a commitment to social justice as central to the social mandate of nursing. Engaging in this knowledge-translation study has provided new perspectives on the complexities, ambiguities and tensions that need to be considered when using the concept of cultural safety to draw attention to racialization, culturalism, and health and health care inequities. The philosophic analysis discussed in this paper represents an epistemological grounding for the concept of cultural safety that links directly to particular moral ends with social justice implications. Although cultural safety is a concept that we have firmly positioned within the paradigm of critical inquiry, ambiguities associated with the notions of 'culture', 'safety', and 'cultural safety' need to be anticipated and addressed if they are to be effectively used to draw attention to critical social justice issues in practice settings. Using cultural safety in practice settings to draw attention to and prompt critical reflection on politicized knowledge, therefore, brings an added layer of complexity. To address these complexities, we propose that what may be required to effectively use cultural safety in the knowledge-translation process is a 'social justice curriculum for practice' that would foster a philosophical stance of critical inquiry at both the individual and institutional levels.

Clinical ethics consultation is largely outside the scope of regulation and oversight, despite its importance. For decades, the bioethics community has been unable to reach a consensus on whether there should be accountability in this work, as there is for other clinical activities that influence the care of patients. The American Society for Bioethics and Humanities, the primary society of bioethicists and scholars in the medical humanities and the organizational home for individuals who perform CEC in the United States, has (...) initiated a two‐step quality attestation process as a means to assess clinical ethics consultants and help identify individuals who are qualified to perform this role. This article describes the process. (shrink)

Amphibian metamorphosis is a post‐embryonic process that systematically transforms different tissues in a tadpole. Thyroid hormone plays a causative role in this complex process by inducing a cascade of gene regulation. While natural metamorphosis does not occur until endogenous thyroid hormone has been synthesized, tadpoles are competent to respond to exogenous thyroid hormone shortly after hatching. In addition, even though the metamorphic transitions of individual organs are all controlled by thyroid hormone, each occurs at distinct developmental stages. Recent molecular studies (...) suggest that this competence of premetamorphic tadpoles to respond to the hormone and the developmental stage‐dependent regulation of tissue‐specific transformations are determined in part by the levels of thyroid hormone receptors and the concentrations of cellular free thyroid hormone. In addition, at least two genes, encoding a cytosolic thyroid hormone binding protein and a 5‐deiodinase, respectively, are likely to be critical players in regulating cellular free thyroid hormone concentrations. This review discusses how all of these molecuar components coordinate to induce amphibian metamorphosis in a correct spatial and temporal manner. These studies provde us with general clues as to how and why tissues become competent to respond to hormonal signals. (shrink)

BackgroundLimited research has been conducted on explanations and understandings of biobanking for future genomic research in African contexts with low literacy and limited healthcare access. We report on the findings of a sub-study on participant understanding embedded in a multi-disease community health screening and biobank platform study known as ‘Vukuzazi’ in rural KwaZulu-Natal, South Africa.MethodsSemi-structured interviews were conducted with research participants who had been invited to take part in the Vukuzazi study, including both participants and non-participants, and research staff that (...) worked on the study. The interviews were transcribed, and themes were identified from the interview transcripts, manually coded, and thematically analysed.ResultsThirty-nine individuals were interviewed. We found that the research team explained biobanking and future genomic research by describing how hereditary characteristics create similarities among individuals. However, recollection and understanding of this explanation seven months after participation was variable. The large volume of information about the Vukuzazi study objectives and procedures presented a challenge to participant recall. By the time of interviews, some participants recalled rudimentary facts about the genetic aspects of the study, but many expressed little to no interest in genetics and biobanking.ConclusionParticipant’s understanding of information related to genetics and biobanking provided during the consent process is affected by the volume of information as well as participant’s interest in the subject matter being discussed. We recommend that future studies undertaking biobanking and genomic research treat explanations of this kind of research to participants as an on-going process of communication between researchers, participants and the community and that explanatory imagery and video graphic storytelling should be incorporated into theses explanations as these have previously been found to facilitate understanding among those with low literacy levels. Studies should also avoid having broader research objectives as this can divert participant’s interest and therefore understanding of why their samples are being collected. (shrink)

Over the last decade, our appreciation of the importance of the nucleolus for cellular function has progressed from the ordinary to the extraordinary. We no longer think of the nucleolus as simply the site of ribosome production, or a dynamic subnuclear body noted by pathologists for its changes in size and shape with malignancy. Instead, the nucleolus has emerged as a key controller of many cellular processes that are fundamental to normal cell homeostasis and the target for dysregulation in many (...) human diseases; in some cases, independent of its functions in ribosome biogenesis. These extra‐nucleolar or new functions, which we term “non‐canonical” to distinguish them from the more traditional role of the nucleolus in ribosome synthesis, are the focus of this review. In particular, we explore how these non‐canonical functions may provide novel insights into human disease and in some cases new targets for therapeutic development. (shrink)

I argue that the contextualist anti-skeptical strategy fails because it misconstrues skepticism by overlooking two important aspects of skepticism: first, all of our knowledge of the external world is brought into question at one fell swoop; second, skepticism depends on certain ideas about sense-perception and its role in our knowledge of the world. Contextualists may have solved ‘the skeptical paradox’ in their own terms, but such a solution cannot in any way make skepticism less threatening to human knowledge or to (...) the philosophical understanding of human knowledge. I also discuss some important aspects of the practice of knowledge attribution in order to show that the more we can make sense of particular knowledge attributions, the less we can take skepticism seriously, and that the practice of knowledge attribution as we understand and engage in it presupposes that we have knowledge of the world.

© 2015 Wong,Tassone,Rivera and Simon.Carriers of the fragile X premutation allele have an expanded CGG trinucleotide repeat size within the FMR1 gene and are at increased risk of developing fragile x-associated tremor/ataxia syndrome. Previous research has shown that male fXPCs with FXTAS exhibit cognitive decline, predominantly in executive functions such as inhibitory control and working memory. Recent evidence suggests fXPCs may also exhibit impairments in processing temporal information. The attentional blink task is often used to examine the dynamics of (...) attentional selection, but disagreements exist as to whether the AB is due to excessive or insufficient attentional control. In this study, we used a variant of the AB task and neuropsychological testing to explore the dynamics of attentional selection, relate AB performance to attentional control, and determine whether fXPCs exhibited temporal and/or attentional control impairments. Participants were adult male fXPCs, aged 18–48 years and asymptomatic for FXTAS and age-matched male controls. We found that fXPCs did not differ from controls in the AB task, indicating that the temporal dynamics of attentional selection were intact. However, they were impaired in the letter-number sequencing task, a test of executive working memory. In the combined fXPC and control group, letter-number sequencing performance correlated positively with AB magnitude. This finding supports models that posit the AB is due to excess attentional control. In our two-pronged analysis approach, in control participants we replicated a previously observed effect and demonstrated that it persists under more stringent theoretical constraints, and we enhance our understanding of fXPCs by demonstrating that at least some aspects of temporal processing may be spared.

DBS Think Tank IX was held on August 25–27, 2021 in Orlando FL with US based participants largely in person and overseas participants joining by video conferencing technology. The DBS Think Tank was founded in 2012 and provides an open platform where clinicians, engineers and researchers can freely discuss current and emerging deep brain stimulation technologies as well as the logistical and ethical issues facing the field. The consensus among the DBS Think Tank IX speakers was that DBS expanded in (...) its scope and has been applied to multiple brain disorders in an effort to modulate neural circuitry. After collectively sharing our experiences, it was estimated that globally more than 230,000 DBS devices have been implanted for neurological and neuropsychiatric disorders. As such, this year’s meeting was focused on advances in the following areas: neuromodulation in Europe, Asia and Australia; cutting-edge technologies, neuroethics, interventional psychiatry, adaptive DBS, neuromodulation for pain, network neuromodulation for epilepsy and neuromodulation for traumatic brain injury.

The etiology of visual hallucinations is largely undetermined in schizophrenia. Collerton et al.'s PAD model partly concurs with what we know about neurocognition in schizophrenia, but we need to specify the types of perceptual and attentional abnormalities that are implicated in recurrent complex visual hallucinations (RCVH). Available data suggest that abnormal attentional control and top-down processing play a larger role than the ventral stream deficits.

A one-day educational intervention with multiple activities was developed and operationalized with a sample of Chinese business students in Hong Kong, China. Its effectiveness in influencing students’ corporate social responsibility orientation was measured with a Chinese version of a forced choice scale using Economic, Legal, Ethical, and Discretionary dimensions by Carroll. A repeated measures multivariate analysis of variance showed significant differences in the Legal and Discretionary dimensions between the post-test Experimental group and Control group ; in the Legal, Ethical, and (...) Discretionary dimensions within the pre-post X group. Such significant differences may be explained by the content of the activities, especially the service learning component. Overall, the intervention appeared effective in influencing students’ CSRO within a Chinese context. Since it was designed upon Western CSR literature, its applicability goes beyond the Chinese community. (shrink)

We present a molecular model of eukaryotic gene transcription. For the β‐globin locus, we hypothesise that a transcription machine composed of multiple RNA polymerase II (PolII) assembles using the locus control region as a foundation. Transcription and locus remodelling can be achieved by pulling DNA through this multi‐PolII ‘reading head’. Once a transcription complex is formed, it may engage an active gene in several rounds of transcription. Observed intergenic sense and antisense transcripts may be the result of PolII pulling the (...) DNA through the reading head whilst searching for the promoter of a gene. Support for this hypothesis is provided using various data from the literature. In the model, DNA is packed in a 30‐nm chromatin fibre, thus gene regulatory regions separated by kilobases are close in space. This, and the need to store transcription‐induced supercoiling, may explain why functionally interacting regions are often separated by many kilobases. (shrink)
