Mental states as macrostates emerging from brain electrical dynamics

Psychophysiological correlations form the basis for different medical and scientific disciplines, but the nature of this relation has not yet been fully understood. One conceptual option is to understand the mental as “emerging” from neural processes in the specific sense that psychology and physiology provide two different descriptions of the same system. Stating these descriptions in terms of coarser- and finer-grained system states (macro- and microstates), the two descriptions may be equally adequate if the coarse-graining preserves the possibility to obtain a dynamical rule for the system. To test the empirical viability of our approach, we describe an algorithm to obtain a specific form of such a coarse-graining from data, and illustrate its operation using a simulated dynamical system. We then apply the method to an electroencephalographic recording, where we are able to identify macrostates from the physiological data that correspond to mental states of the subject

Spreading order: religion, cooperative niche construction, and risky coordination problems

Adaptationists explain the evolution of religion from the cooperative effects of religious commitments, but which cooperation problem does religion evolve to solve? I focus on a class of symmetrical coordination problems for which there are two pure Nash equilibriums: (1) ALL COOPERATE, which is efficient but relies on full cooperation; (2) ALL DEFECT, which is inefficient but pays regardless of what others choose. Formal and experimental studies reveal that for such risky coordination problems, only the defection equilibrium is evolutionarily stable. The following makes sense of otherwise puzzling properties of religious cognition and cultures as features of cooperative designs that evolve to stabilise such risky exchange. The model is interesting because it explains lingering puzzles in the data on religion, and better integrates evolutionary theories of religion with recent, well-motivated models of cooperative niche construction

High fat diet induces dysregulation of hepatic oxygen gradients and mitochondrial function in vivo

NAFLD (non-alcoholic fatty liver disease), associated with obesity and the cardiometabolic syndrome, is an important medical problem affecting up to 20% of western populations. Evidence indicates that mitochondrial dysfunction plays a critical role in NAFLD initiation and progression to the more serious condition of NASH (non-alcoholic steatohepatitis). Herein we hypothesize that mitochondrial defects induced by exposure to a HFD (high fat diet) contribute to a hypoxic state in liver and this is associated with increased protein modification by RNS (reactive nitrogen species). To test this concept, C57BL/6 mice were pair-fed a control diet and HFD containing 35% and 71% total calories (1 cal≈4.184 J) from fat respectively, for 8 or 16 weeks and liver hypoxia, mitochondrial bioenergetics, NO (nitric oxide)-dependent control of respiration, and 3-NT (3-nitrotyrosine), a marker of protein modification by RNS, were examined. Feeding a HFD for 16 weeks induced NASH-like pathology accompanied by elevated triacylglycerols, increased CYP2E1 (cytochrome P450 2E1) and iNOS (inducible nitric oxide synthase) protein, and significantly enhanced hypoxia in the pericentral region of the liver. Mitochondria from the HFD group showed increased sensitivity to NO-dependent inhibition of respiration compared with controls. In addition, accumulation of 3-NT paralleled the hypoxia gradient in vivo and 3-NT levels were increased in mitochondrial proteins. Liver mitochondria from mice fed the HFD for 16 weeks exhibited depressed state 3 respiration, uncoupled respiration, cytochrome c oxidase activity, and mitochondrial membrane potential. These findings indicate that chronic exposure to a HFD negatively affects the bioenergetics of liver mitochondria and this probably contributes to hypoxic stress and deleterious NO-dependent modification of mitochondrial proteins

Mind Perception Is the Essence of Morality

Mind perception entails ascribing mental capacities to other entities, whereas moral judgment entails labeling entities as good or bad or actions as right or wrong. We suggest that mind perception is the essence of moral judgment. In particular, we suggest that moral judgment is rooted in a cognitive template of two perceived minds—a moral dyad of an intentional agent and a suffering moral patient. Diverse lines of research support dyadic morality. First, perceptions of mind are linked to moral judgments: dimensions of mind perception (agency and experience) map onto moral types (agents and patients), and deficits of mind perception correspond to difficulties with moral judgment. Second, not only are moral judgments sensitive to perceived agency and experience, but all moral transgressions are fundamentally understood as agency plus experienced suffering—that is, interpersonal harm—even ostensibly harmless acts such as purity violations. Third, dyadic morality uniquely accounts for the phenomena of dyadic completion (seeing agents in response to patients, and vice versa), and moral typecasting (characterizing others as either moral agents or moral patients). Discussion also explores how mind perception can unify morality across explanatory levels, how a dyadic template of morality may be developmentally acquired, and future directions

The function of fear in institutional maintenance: Feeling frightened as an essential ingredient in haute cuisine

Fear is a common and powerful emotion that can regulate behaviour. Yet institutional scholars have paid limited attention to the function of fear in processes of institutional reproduction and stability. Drawing on an empirical study of elite chefs within the institution of haute cuisine, this article finds that the multifaceted emotion of fear characterised their experiences and served to sustain their institution. Chefs’ individual feelings of fear prompted conformity and a cognitive constriction, which narrowed their focus on to the precise reproduction of traditional practices whilst also limiting challenges to the norms underpinning the institution. Through fear work, chefs used threats and violence to connect individual experiences of fear to the violation of institutionalized rules, sustaining the conditions in which fear-driven maintenance work thrived. The study also suggests that fear is a normative element of haute cuisine in its own right, where the very experience and eliciting of fear preserved an essential institutional ingredient. In this way, emotions such as fear do not just accompany processes of institutionalization but can be intimately involved in the maintenance of institutions

Cultural theory and the dynamics of organizational change: the response of housing associations in London to the Housing Act 1988

The aim of this article is to consider the most effective way of conceptualizing a sector that has undergone radical change: the UK voluntary housing sector. The article considers existing accounts of housing associations and classifies these into five analytically distinct groups: practitioners, historical accounts, managerialist approaches, network theorists and institutionalist accounts. The main contention is that each of these is limited in explanatory potential, primarily due to their neglect of culture. This article proposes a more detailed framework for developing an understanding of the substantial changes affecting housing associations since the 1980s; that offered by "grid-group cultural theory". The article provides longitudinal qualitative data obtained from London housing associations to support the contention that organizational change can most usefully be understood by reference to the cultural themes of hierarchy and individualism. The article contends that cultural theory offers the opportunity to develop a systematic analysis that accounts for institutional history and organizational differentiation
