The choreographies of the elimination of faeces:An ethnographic study of the institutionalized body care practices of older people in different health care settings

AimTo explore the choreographies of the elimination of faeces of older people to gain insight into the institutionalized practices of body care of older people in hospitals and long-term care settings.DesignA qualitative ethnographic study, drawing on a perspective of socio-material theory. Reported in accordance with the Standards for Reporting Qualitative Research.MethodsA total of, 30 women and 11 men aged 80 years and above needing assistance with body care in a hospital ward, 2 nursing homes and home care and 32 care workers participated. Four individual interviews with older people and three focus group interviews with care workers were conducted, in addition to 135 h of participant observations, from December 2020 to September 2021. Data were analysed using a situational analysis approach.ResultsThe assistance with the elimination of faeces is a multiplicity of ongoing dynamic practices where different actors interrelate. Dominating actors are time, space, materialities, different ideals and professional knowledge. The choreographies aim at order the elimination of faeces to happen at the right time at the right place, to provide dignified care.ConclusionTo assist older people with the elimination of faeces is complex institutionalized practices. The study argues for a greater focus on the ongoing relations between human and non-human actors to provide new understandings of an underexplored phenomenon in nursing

Comprehensive review:Computational modelling of Schizophrenia

Computational modelling has been used to address: (1) the variety of symptoms observed in schizophrenia using abstract models of behavior (e.g. Bayesian models - top-down descriptive models of psychopathology); (2) the causes of these symptoms using biologically realistic models involving abnormal neuromodulation and/or receptor imbalance (e.g. connectionist and neural networks - bottom-up realistic models of neural processes). These different levels of analysis have been used to answer different questions (i.e. understanding behavioral vs. neurobiological anomalies) about the nature of the disorder. As such, these computational studies have mostly supported diverging hypotheses of schizophrenia's pathophysiology, resulting in a literature that is not always expanding coherently. Some of these hypotheses are however ripe for revision using novel empirical evidence.Here we present a review that first synthesizes the literature of computational modelling for schizophrenia and psychotic symptoms into categories supporting the dopamine, glutamate, GABA, dysconnection and Bayesian inference hypotheses respectively. Secondly, we compare model predictions against the accumulated empirical evidence and finally we identify specific hypotheses that have been left relatively under-investigated

Charles Bonnet Syndrome:Evidence for a Generative Model in the Cortex?

Several theories propose that the cortex implements an internal model to explain, predict, and learn about sensory data, but the nature of this model is unclear. One condition that could be highly informative here is Charles Bonnet syndrome (CBS), where loss of vision leads to complex, vivid visual hallucinations of objects, people, and whole scenes. CBS could be taken as indication that there is a generative model in the brain, specifically one that can synthesise rich, consistent visual representations even in the absence of actual visual input. The processes that lead to CBS are poorly understood. Here, we argue that a model recently introduced in machine learning, the deep Boltzmann machine (DBM), could capture the relevant aspects of (hypothetical) generative processing in the cortex. The DBM carries both the semantics of a probabilistic generative model and of a neural network. The latter allows us to model a concrete neural mechanism that could underlie CBS, namely, homeostatic regulation of neuronal activity. We show that homeostatic plasticity could serve to make the learnt internal model robust against e.g. degradation of sensory input, but overcompensate in the case of CBS, leading to hallucinations. We demonstrate how a wide range of features of CBS can be explained in the model and suggest a potential role for the neuromodulator acetylcholine. This work constitutes the first concrete computational model of CBS and the first application of the DBM as a model in computational neuroscience. Our results lend further credence to the hypothesis of a generative model in the brain

GRI - a tool for companies to fabricate a sustainable reality?

In society today, there is a great focus on sustainability and that companies should contribute to sustainable development. One way to do this is through transparency between the company and its stakeholders regarding how they work on these important issues. This is done through sustainability reports that can be designed in different ways, but this study focuses on those that follow the Global Reporting Initiative, which is the dominant framework globally.   Prior research has shown mixed conclusions regarding GRI and its usefulness. In these, both positive and negative aspects of the framework have been highlighted. This study examines what and how high and low ranked businesses based on SBI report to study the usefulness of GRI. In addition, various theories will be used to examine what may be the reasons for the similarities and differences between the groups. This result is also related to prior research that studied sustainability reporting in connection with the selected theories.   The study was conducted as a method where qualitative data was quantified through a quantitative content analysis. The sustainability reports of 32 companies were reviewed based on their GRI-index and data was then statistically tested using Chi-square-tests and a Fisher's exact test. The study shows that there is no significant difference in what the high and low ranked businesses report. This difference applies to the total number of indicators as well as within the different series, economic, environmental and social. Regarding how the companies report, the study shows that the low ranked businesses are more likely to report indicators for which they do not meet the requirements, this result is also statistically significant. The reasons for the similarities and differences that were identified can be discussed in relations to institutional theory, legitimacy theory and stakeholder theory
