The comorbidity of chronic pain and opioid addiction is a serious problem that has been growing with the practice of prescribing opioids for chronic pain. Neuroimaging research has shown that chronic pain and opioid dependence both affect brain structure and function, but this is the first study to evaluate the neurophysiological alterations in patients with comorbid chronic pain and addiction. Eighteen participants with chronic low back pain and opioid addiction were compared with eighteen age- and sex-matched healthy individuals in a (...) pain-induction fMRI task. Unified structural equation modeling (SEM) with Lagrange multiplier (LM) testing yielded a network model of pain processing for patient and control groups based on 19 a priori defined regions. Tests of differences between groups on specific regression parameters were determined on a path-by-path basis using z-tests corrected for the number of comparisons. Patients with the chronic pain and addiction comorbidity had increased connection strengths; many of these connections were interhemispheric and spanned regions involved in sensory, affective, and cognitive processes. The affected regions included those that are commonly altered in chronic pain or addiction alone, indicating that this comorbidity manifests with neurological symptoms of both disorders. Understanding the neural mechanisms involved in the comorbidity is crucial to finding a comprehensive treatment, rather than treating the symptoms individually. (shrink)

We implemented a user-centered approach to the design of an artificial intelligence (AI) system that provides users with access to information about the workings of the United States federal court system regardless of their technical background. Presently, most of the records associated with the federal judiciary are provided through a federal system that does not support exploration aimed at discovering systematic patterns about court activities. In addition, many users lack the data analytical skills necessary to conduct their own analyses and (...) convert data into information. We conducted interviews, observations, and surveys to uncover the needs of our users and discuss the development of an intuitive platform informed from these needs that makes it possible for legal scholars, lawyers, and journalists to discover answers to more advanced questions about the federal court system. We report on results from usability testing and discuss design implications for AI and law practitioners and researchers. (shrink)

Multifunctional agricultural systems seek to expand upon production-based benefits to enhance family wellbeing and animal health, reduce inputs, and improve environmental services such as biodiversity and water quality. However, in many countries a landscape-level conversion is uneven at best and stalled at worst. This is particularly true across the eastern rural landscape in the United States. We explore the role of social networks as drivers of system transformation within dairy production in the eastern United States, specifically rotational grazing as an (...) alternative management option. We hypothesize the importance of weak ties within farmer social networks as drivers of change. In Wisconsin, Pennsylvania, and New York, we conducted 53 interviews with confinement, low-intensity, and rotational grazing dairy producers as well as 35 interviews with associated network actors. Though confinement and grazier networks had similar proportions of strong and weak ties, confinement producers had more market-based weak ties, while graziers had more weak-ties to government agencies and other graziers in the region. These agency weak ties supported rotational graziers through information exchange and cost sharing, both crucial to farmers’ transitions from confinement-based production to grazing systems. While weak ties were integral to initial innovation, farmers did not maintain these relationships beyond their transition to grazing. Of equal importance, grazier weak-tie networks did not include environmental organizations, suggesting unrealized potential for more diverse networks based on environmental services. By understanding the drivers, we can identify barriers to expanding weak tie networks and emergent properties in order to create institutions and policies necessary for change. (shrink)

The professional mining engineer has a number of different duties. He must: produce engineering designs, meet the production requirements set by the mining operation he works for, ensure efficient cooperation between the different departments in a mine, and he is responsible for mine planning. Also, and very importantly, he is responsible for meeting high safety standards and ensuring that his mine is as injury and fatality free as possible. However, it is unfortunately the case that accidents do occur in mines, (...) and that miners are sometimes injured or even killed. Such tragedies raise questions about whether the mining engineer bears some responsibility for the injuries or deaths. In this paper, we argue that the engineer does bear responsibility, but that depending on the circumstances surrounding any particular accident, ascriptions of moral responsibility do not always mean that the engineer is morally blameworthy. We conclude that professional accountability and moral responsibility require that the mining engineer take practical steps to ensure that high safety standards are upheld, and that, when accidents occur, steps are taken to identify the causes so that similar tragedies can be avoided in the future.

On several key issues we agree with the commentators. Perhaps most importantly, everyone seems to agree that psychology has an important role to play in building better models of human vision, and (most) everyone agrees (including us) that deep neural networks (DNNs) will play an important role in modelling human vision going forward. But there are also disagreements about what models are for, how DNN–human correspondences should be evaluated, the value of alternative modelling approaches, and impact of marketing hype in (...) the literature. In our view, these latter issues are contributing to many unjustified claims regarding DNN–human correspondences in vision and other domains of cognition. We explore all these issues in this response. (shrink)

Deep neural networks (DNNs) have had extraordinary successes in classifying photographic images of objects and are often described as the best models of biological vision. This conclusion is largely based on three sets of findings: (1) DNNs are more accurate than any other model in classifying images taken from various datasets, (2) DNNs do the best job in predicting the pattern of human errors in classifying objects taken from various behavioral datasets, and (3) DNNs do the best job in predicting (...) brain signals in response to images taken from various brain datasets (e.g., single cell responses or fMRI data). However, these behavioral and brain datasets do not test hypotheses regarding what features are contributing to good predictions and we show that the predictions may be mediated by DNNs that share little overlap with biological vision. More problematically, we show that DNNs account for almost no results from psychological research. This contradicts the common claim that DNNs are good, let alone the best, models of human object recognition. We argue that theorists interested in developing biologically plausible models of human vision need to direct their attention to explaining psychological findings. More generally, theorists need to build models that explain the results of experiments that manipulate independent variables designed to test hypotheses rather than compete on making the best predictions. We conclude by briefly summarizing various promising modeling approaches that focus on psychological data. (shrink)

If humanism is not equal to scientific naturalism, atheism, skepticism, or secularism, what then is humanism?

To better understand the influence of religiosity and spirituality on moral reasoning, 1,037 college students completed a survey including demographic questions, a religiosity measure, a spirituality measure, and Forsyth's Ethical Position Questionnaire. Religiosity and spirituality positively correlated with moral idealism, whereas spirituality negatively correlated with moral relativism. However, religiosity and spirituality accounted for a very little variability in moral reasoning, suggesting that they do not directly influence moral reasoning. In addition, female participants reported higher spirituality, but there were no gender (...) differences on a spirituality measure. Future research is needed to examine other factors that may influence moral reasoning. (shrink)

The South China Sea territorial dispute has been a contentious issue in the international community. In the course of 3 years, China and the Philippines had undergone arbitral proceedings over the maritime rights and entitlements in the South China Sea. As the Permanent Court of Arbitration reached its decision, this paper aims to examine the interpretation process of the Arbitral Tribunal in the judgment of the South China Sea conflict between China and the Philippines. The primary objective of the study (...) is to reconstruct or explain how the Tribunal came up with its interpretation of the written arguments presented by the parties involved and to distinguish whether such reconstruction the Tribunal has successfully interpreted or made sense of the said arguments and submissions. Doing so would necessitate a pragmatic analysis– the relevance-theoretic account of human communication and cognition. Data analyzed include written submissions and arguments as well as the legal documents used during the arbitral process. Using content analysis, the data were evaluated through applying the tool of interpretation based on the criteria set by the three conditions of the relevance theory: logical condition, pragmatic condition, and condition of optimal relevance. This paper argues that in order for the addressee of an utterance, in this case the Arbitral Tribunal, to attain a successful interpretation, it should meet these three conditions. This study found that the reconstruction of the interpretation based on the three conditions showed that the Tribunal had attained a valid and correct interpretation of the Philippines’ and China’s arguments. Furthermore, the paper asserts that implied conclusion and the contextual assumptions can be a guiding principle for the cognitive comprehension or interpretation of legal texts. (shrink)

In the United States, approximately 2.53 million people sustain a concussion each year. Relative to adults, youth show greater cognitive deficits following concussion and a longer recovery. An accurate and reliable imaging method is needed to determine injury severity and symptom resolution. The primary objective of this study was to characterize concussions with diffusion tensor imaging. This was performed through a normative Z-scoring analysis of DTI metrics, fractional anisotropy, axial diffusivity, and radial diffusivity, to quantify patient-specific injuries and identify commonly (...) damaged brain regions in paediatric concussion patients relative to healthy controls. It was hypothesized that personalizing the detection analysis through normative Z-scoring would provide an understanding of trauma-induced microstructural damage. Concussion patients were volunteers recruited from the Emergency Department of the McMaster Children’s Hospital with a recent concussion, 9 males and 17 females, mean age 14.22 ± 2.64, while healthy paediatric brain DTI datasets were obtained from an MRI data repository. Significant abnormalities were commonly found in the longitudinal fasciculus, fronto-occipital fasciculus, and corticospinal tract, while unique abnormalities were localized in a number of other areas reflecting the individuality of each child’s injury. Total injury burden, determined by the number of regions containing outliers per DTI metric per patient, was used as the metric to quantify the overall injury severity of each patient. The primary outcome of this analysis found that younger patients experienced a significantly greater injury burden when measured using fractional anisotropy. These results show that DTI was able to detect microstructural changes caused by concussion, on a per-person basis, and has the potential to be a useful tool for improving diagnostic accuracy and prognosis of a concussion.

The success of assisted reproductive technologies (ARTs) worldwide has led to an accumulation of frozen embryos that are surplus to the reproductive needs of those for whom they were created. In these situations, couples must decide whether to discard them or donate them for scientific research or for use by other infertile couples. While legislation and regulation may limit the decisions that couples make, their decisions are often shaped by their religious beliefs. Unfortunately, health professionals, scientists and policy-makers are often (...) unaware of the way in which faith traditions view ART and decisions concerning the ‘fate’ of surplus embryos. In this paper scholars representing six major religious traditions provide a commentary on a hypothetical case concerning the donation or destruction of excess ART embryos. These commentaries provide a rich account of religious perspectives on the status of the human embryo and an insight into the relevance of faith to health and policy decisions, particularly in reproductive medicine, ART and embryo research.

Plato's Republic has proven to be of astounding influence and importance. Justly celebrated as Plato's central text, it brings together all of his prior works, unifying them into a comprehensive vision that is at once theological, philosophical, political, and moral. These essays provide a state-of-the-art research picture of the most interesting aspects of the Republic, and address questions that continue to puzzle and provoke, such as: Does Plato succeed in his argument that the life of justice is the most attractive (...) one? Is his tripartite analysis of the soul coherent and plausible? Why does Plato seem to have to force his philosopher-guardians to rule when they know this is something that they ought to do? What is the point of the strange and complicated closing Myth of Er? This volume will be essential to those looking for thoughtful and detailed excursions into the problems posed by Plato's text and ideas. (shrink)

From Bishop Wilberforce in the 1860s to the advocates of "creation science" today, defenders of traditional mores have condemned Darwin's theory of evolution as a threat to society's values. Darwin's defenders, like Stephen Jay Gould, have usually replied that there is no conflict between science and religion--that values and biological facts occupy separate realms. But as James Rachels points out in this thought-provoking study, Darwin himself would disagree with Gould. Darwin, who had once planned on being a clergyman, was convinced (...) that natural selection overthrew our age-old religious beliefs. Created from Animals offers a provocative look at how Darwinian evolution undermines many tenets of traditional philosophy and religion. James Rachels begins by examining Darwin's own life and work, presenting an astonishingly vivid and compressed biography. We see Darwin's studies of the psychological links in evolution (such as emotions in dogs, and the "mental powers" of worms), and how he addressed the moral implications of his work, especially in his concern for the welfare of animals. Rachels goes on to present a lively and accessible survey of the controversies that followed in Darwin's wake, ranging from Herbert Spencer's Social Darwinism to Edward O. Wilson's sociobiology, and discusses how the work of such influential intellects as Descartes, Hume, Kant, T.H. Huxley, Henri Bergson, B.F. Skinner, and Stephen Jay Gould has contributed to--or been overthrown by--evolutionary science. Western philosophy and religion, Rachels argues, have been shaken by the implications of Darwin's work, most notably the controversial idea that humans are simply a more complex kind of animal. Rachels assesses a number of studies that suggest how closely humans are linked to other primates in behavior, and then goes on to show how this idea undercuts the work of many prominent philosophers. Kant's famous argument that suicide reduces one to the level of an animal, for instance, is meaningless if humans are, in fact, animals. Indeed, humanity's membership in the animal kingdom calls into question the classic notions of human dignity and the sacredness of human life. What we need now, Rachels contends, is a philosophy that does not discriminate between different species, one that addresses each being on an individual basis. With this sweeping survey of the arguments, the philosophers, and the deep implications surrounding Darwinism, Rachels lays the foundations for a new view of morality. Vibrantly written and provocatively argued, Created from Animals offers a new perspective on issues ranging from suicide to euthanasia to animal rights. (shrink)

Broadband internet access is a super-determinant of health that plays an important role in healthcare and public health outcomes. Laws and policies shape implementation and use of broadband for healthcare and public health. Connecting broadband and telehealth laws with their health impacts, through legal epidemiological research, enables states to make evidence-based decisions to improve health outcomes for underserved populations.

California is a landmark setting for studying produce recovery efforts and policy implications because of its global relevance in agricultural production, its complex network of food recovery organizations, and its environmental and public health regulations. Through a series of focus groups with organizations involved in produce recovery (gleaning organizations) and emergency food operations (food banks, food pantries), this study aimed to deepen our understanding of the current produce recovery system and determine the major challenges and opportunities related to the produce (...) recovery system. Operational and systematic barriers to produce recovery were highlighted by both gleaning and emergency food operations. Operational barriers, such as the lack of appropriate infrastructure and limited logistical support were found to be a challenge across groups and were directly tied to inadequate funding for these organizations. Systematic barriers, such as regulations related to food safety or reducing food loss and waste, were also found to impact both gleaning and emergency food organizations, but differences were observed in how each type of regulation impacted each stakeholder group. To support the expansion of food recovery efforts, participants expressed need for better coordination within and across food recovery networks and more positive and transparent engagement from regulators to increase understanding of the specifics of their unique operational constraints. The focus group participants also provided critiques on how emergency food assistance and food recovery are inscribed within the current food system and for longer term goals of reducing food insecurity and food loss and waste a systematic change will be required.

Memorialization in the form of the architectural statue can suggest that our stance towards the past is concrete while memorials in the form of repeated social activity represent reconciliation with the past as a continual process. Enacted memorials suggest that reconciliation with the past is not itself a thing of the past. Each generation must grapple with its inherited memories, guilt, and grief and self-consciously take its own stance towards that which came before it. This article considers Dominik Smole’s post (...) World War II rewrite of Antigona as an enacted memorial within the context of socialist Yugoslavia. The practice of restaging Antigona in Slovenia may be seen as the practice of meta-memorialization, which routinely returns to the past while openly weighing the dangers of awakening the unburied dead against the dangers of letting the unaddressed conflicts of the past sleep.

When ethics committees are consulted about patients who have or need court-appointed guardians, they lack empirical evidence about several common issues, including the relationship between guardianship and prolonged, potentially medically unnecessary hospitalizations for patients. To provide information about this issue, we conducted quantitative and qualitative analyses using a retrospective cohort from Veterans Healthcare Administration. To examine the relationship between guardianship appointment and hospital length of stay, we first compared 116 persons hospitalized prior to guardianship appointment to a comparison group (n (...) = 348) 3:1 matched for age, diagnosis, date of admission, and comorbidity. We then compared 91 persons hospitalized in the year following guardianship appointment to a second matched comparison group (n = 273). Mean length of stay was 30.75 days (SD = 46.70) amongst those admitted prior to guardianship, which was higher than the comparison group (M = 7.74, SD = 9.71, F = 20.75, p. (shrink)

A new reading of Plato's account of conventionalism about names in the Cratylus. It argues that Hermogenes' position, according to which a name is whatever anybody 'sets down' as one, does not have the counterintuitive consequences usually claimed. At the same time, Plato's treatment of conventionalism needs to be related to his treatment of formally similar positions in ethics and politics. Plato is committed to standards of objective natural correctness in all such areas, despite the problematic consequences which, as he (...) himself shows, arise in the case of language. (shrink)

Hume's position in ethics, which is based on his empiricist theory of the mind, is best known for asserting four theses: (1) Reason alone cannot be a motive to the will, but rather is the slave of the passions (see Section 3) (2) Moral distinctions are not derived from reason (see Section 4). (3) Moral distinctions are derived from the moral sentiments: feelings of approval (esteem, praise) and disapproval (blame) felt by spectators who contemplate a character trait or action (see (...) Section 7). (4) While some virtues and vices are natural (see Section 13), others, including justice, are artificial (see Section 9). There is heated debate about what Hume intends by each of these theses and how he argues for them. He articulates and defends them within the broader context of his metaethics and his ethic of virtue and vice. Hume's main ethical writings are Book 3 of his Treatise of Human Nature, Of Morals (which builds on Book 2, Of the Passions), his Enquiry concerning the Principles of Morals, and some of his Essays. In part the moral Enquiry simply recasts central ideas from the moral part of the Treatise in a more accessible style; but there are important differences. The ethical positions and arguments of the Treatise are set out below, noting where the moral Enquiry agrees; differences between the Enquiry and the Treatise are discussed afterwards. (shrink)

Semifactual thinking about what might have been the same, e.g., ''even if Philip had not chosen the chocolate ice-cream sundae, he would have developed an allergic reaction'' has been neglected compared to counterfactual thinking about what might have been different, e.g., ''if only Philip had not chosen the chocolate ice-cream sundae, he would not have developed an allergic reaction''. We report the first systematic comparison of the two sorts of thinking in two experiments. The first experiment showed that counterfactual ''if (...) only'' thoughts about an antecedent event lead people to judge the event to be more causally related to the outcome, whereas semifactual ''even if'' thoughts lead people to judge the antecedent event to be less causally related to the outcome. In addition, the experiment showed that generating counterfactual ''if only'' thoughts increases emotional reactions such as regret, whereas generating semifactual ''even if'' thoughts decreases such reactions. The second experiment, along with a replication experiment, showed that when people complete ''if only'' and ''even if'' sentence stems, they focus on different alternative antecedents to the outcome: ''if only'' thoughts focus on alternatives that would undo the outcome whereas ''even if'' thoughts focus on alternatives that would not undo it, from among a set of available alternative antecedents in which either all, some, or none would undo the outcome. The implications of the results for theories of thinking about what might have been are discussed. (shrink)
