Brian Leiter (2016) throws down two gauntlets to philosophers engaged in dialogue with the broader public. If, with the first, public philosophers recognize that they cannot offer substantive answers but only sophisticated method, they nevertheless fail to realize that said method does not resonate with the very public whom they purport to help. For, with the second, that method does not engage the emotivist and tribalist cast of contemporary public discourse: emotivist because a person’s moral and political beliefs are a function of emotional attitudes or affective responses for which she adduces reasons post hoc; tribalist because the person tracks not the inferential relation between beliefs but her similarity with interlocutors. In order to understand the full extent of this critique, it is necessary, first, to parse strands of public philosophy, distinct discursive sites, and pictures of philosophical practice and, then, to probe the critique’s empirical groundedness and intended scope. These elements in place, it is then possible to sketch public philosophy reconceived along Leiter’s lines as equal part rigor and rhetoric. That sketch may be somewhat filled out through two tactics employed in Jeffrey Stout’s (2004, 2010) work. These form part of a toolkit for philosophical dialogue whereby philosophers get a discursive grip on non-discursive factors underlying public discourse and push back on Leiter's dilemma. [less ▲]

We investigate the impact of corruption on tax compliance using a sample of 700 small business in Bamako, Mali. The main contribution of this paper is to focus on micro-enterprises (including semi-formal and informal ones), while existing works concentrate on large and formal firms. Our results show that (i) even very small firms pay taxes (two-thirds of firms pay taxes in our sample); and, (ii) paying bribes reduces significantly tax compliance. This latter finding is robust (i) to the addition of a set of control variables accounting for other determinants, (ii) to treatment for endogeneity, and (iii) the use of a different proxy for tax compliance.

Early life adversity (ELA) has been associated with inflammation and immunosenescence, as well as hyporeactivity of the HPA-axis. As the immune system and HPA-axis are tightly intertwined around the glucocorticoid receptor (GR) we examined peripheral GR functionality in the EpiPath cohort, where participants had either been exposed to ELA (separation from parents and/or institutionalization followed by adoption) (n=40) or had been reared by their biological parents (n=72). Expression of the strict GR target genes FKBP5 and GILZ as well as total and 1F and 1H GR transcripts were similar between groups. Furthermore, there were no differences in GR sensitivity, examined by the effects of dexamethasone on IL6 production in LPS-stimulated whole blood. Although we did not find differences in methylation at the GR 1F exon or promoter region, we identified a region of the GR 1H promoter (CpG 1-9) that showed lower methylation levels in ELA. Peripheral GR signaling was unperturbed in our cohort and the observed immune phenotype does not appear to be secondary to an altered glucocorticoid receptor response to glucocorticoids. To identify signaling pathways that may underlie the ELA immune phenotype, future research should focus on unbiased approaches, such as investigating whole genome methylation profiles. [less ▲]

Background: Parental divorce has been associated with reduced well-being in young adults. It is, however, unclear whether this finding is clinically relevant as studies using structural clinical interviews are missing. This study, therefore, investigated if young adults with divorced parents are at risk to develop mental disorders. Furthermore, differences in parental care, social connectedness, chronic stress and traumatic experiences between children of divorced and non-divorced parents were investigated. Methods: 121 women (mean age: 23 years) were interviewed using the Structured Clinical Interview for DSMIV Axis I (i.e., major mental disorders) and II (i.e., personality disorders) Disorders and asked to complete questionnaires assessing parental care, social connectedness (loneliness, attachment anxiety and avoidance), chronic stress, childhood trauma and depression. Results: Young adults of divorced parents had a higher risk for Axis I but not Axis II disorders as compared to young adults of non-divorced parents. Participants from divorced families as compared to non-divorced families reported more depression, loneliness, childhood trauma, attachment avoidance, attachment anxiety, chronic stress and less parental care. Limitations: Due to the cross-sectional design of this study, conclusions about causality remain speculative. Conclusion: The increased vulnerability of children of divorced parents to develop mental disorders, and to experience more chronic stress, loneliness, attachment avoidance, attachment anxiety, and traumatic experiences during childhood is alarming and highlights the importance of prevention programs and psycho-education during the process of parental divorce. Parental support with regard to adequate caregiving is needed to help parents to better support their children during and after their divorce. [less ▲]

Introduction Diabetes mellitus prevalence is estimated between 3.1% and 4.3% in Rwanda. To address non-communicable diseases and the shortage of health workforce, the Rwandan Ministry of Health has introduced Home-Based Care Practitioners (HBCPs): laypeople provide longitudinal care to chronic patients after receiving a six-month training. Leveraging technological mobile solutions may also help improve health and health care. The D²Rwanda study aims at: a) determining the efficacy of an integrated programme for the management of diabetes in Rwanda, which will provide monthly patient assessments by HBCPs, and an educational and self-management mHealth patient tool, and; b) exploring qualitatively the ways the interventions will have been enacted, their challenges and effects, and changes in the patients’ health behaviours and HBCPs’ work satisfaction. Methods and analysis This is a mixed methods sequential explanatory study. Firstly, there will be a one-year cluster randomised controlled trial including two interventions [(1) HBCPs programme; (2) HBCPs programme + mobile health application] and usual care (control). Currently, nine hospitals run the HBCPs programme. Under each hospital, administrative areas implementing the HBCPs programme will be randomised to receive intervention 1 or 2. Eligible patients from each area will receive the same intervention. Areas without the HBCPs programme will be assigned to the control group. The primary outcome will be changes in HbA1c. Secondary outcomes include medication adherence, mortality, complications, health-related quality of life, diabetes-related distress and health literacy. Secondly, at the end of the trial, focus group discussions will be conducted with patients and HBCPs. Financial support was received from the Karen Elise Jensens Fond, and the Universities of Aarhus and Luxembourg. Ethics and dissemination Ethics approval was obtained from the Rwanda National Ethics Committee and the Ethics Review Panel of the University of Luxembourg. Findings will be disseminated via peer-reviewed publications and conference presentations. Clinical trial registration NCT03376607 [less ▲]

Purpose of Review The 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) categorizes gambling disorder in the section on substance-related and addictive disorders, and the 11th revision of the International Classification of Diseases (ICD-11) includes both gambling and gaming disorder as disorders due to addictive behaviors. However, there is less evidence for other putative behavioral addictions. This review focuses on requirements for epidemiological studies of disorders that may be considered as behavioral addictions and compares the current state of research with principles of sound epidemiological research. Recent Findings In studies of behavioral addictions, samples are often quite small, which may lead to increased random error. The lack of sound assessment tools—particularly the lack of agreed-upon diagnostic criteria and standardized diagnostic interviews—may also increase systematic error. Other concerns related to systematic bias include the use of convenience samples, lack of pro-active recruitment, inadequate assessment of confounding variables, and a dearth of representative and longitudinal studies. Summary This review recommends that future studies of putative behavioral addictions should more closely adhere to methodological standards of epidemiological research to reduce random and systematic error. Specific recommendations are detailed to advance epidemiological research in this area with the aim of improving the evidence base and generating more refined public health recommendations and policies.

Long-term behaviour of concrete structural elements is very important for evaluation of its health and serviceability range. The phenomena that must be considered are complex and lead to coupled multiphysics formulations. Such formulations are difficult not only from physical perspective, but also from computational perspective. In this contribution attention to computational efficiency and effective implementation is payed. Presented model for concrete ageing is based on microprestress-solidification (MPS) theory of Bazant [1], Kunzel’s model for heat and moisture transport [2] and Mazars model for damage [3]. Ageing linear viscoelastic response, which is immanent to MPS theory and concrete creep, leads to ordinary differetial equation for internal variables solved for every quadrature/nodal point. Numerical structure of the finite element discretisation is examined. Few simplifications on physical model lead to a very efficient linear algebra problem for which standard preconditioned Krylov solvers are reviewed. In parallel, weak and strong scaling tests are performed. All results are produced within open-source finite element framework FEniCS [4]. These models are usually a basis for more involved thermo-hygro-chemo-mechanical (THCM) models with migrating chemical species. It is anticipated, that presented results will help practitioners or other structural engineerers with the choice of suitable and efficient methods for long-term concrete modeling. [less ▲]

Nevertheless, the workshop focused on the newly incorporated Fortunoff Video Archive (FVA) that belongs to the category of long-awaited ingestion, and the path to get a licence was more than difficult. The archive represents a new source for all scholars including me, but in this short comment, I would like to critically point out to several minor drawbacks. [less ▲]

Calls for multilingual pedagogies have reached early childhood education and some programmes have been implemented in Europe. However, their focus frequently remains on the majority language and home languages are given little space. For multilingual programmes to be inclusive and empowering, professionals need to break with monolingual practices based on monolingual ideologies. The resource-oriented pedagogy of translanguaging which challenges hegemonic practices, is one way in which professionals can give space to all languages, leverage children’s resources and contribute to their development. The present chapter presents the findings of a professional development on multilingual pedagogies in Luxembourg. Data stem from observations, video-recorded activities and interviews with four practitioners, two working in a formal education setting and two in a non-formal one. The findings show that the practitioners developed a positive stance towards translanguaging and multilingual education, learned to design a child-centred and holistic multilingual learning environment and used languages flexibly, deploying translation, code-switching and translanguaging. This dynamic language use facilitated communication, participation, language learning and well-being. There were differences between the practitioners’ flexible language use. The professionals in the school did not use pair talk, made less use of code-switching and used languages more strategically and responsibly than the caregivers in the crèche. [less ▲]
