Saudi service users' perceptions and experiences of the quality of their mental health care provision in the Kingdom of Saudi Arabia (KSA): A qualitative inquiry.

This paper presents, as part of a larger mixed-methods design, a study generating a theoretical understanding of issues pertinent to the quality of mental health care in the KSA from the perspective of those using services. Semi-structured interviews were undertaken with thirty service users admitted to inpatient psychiatric wards, using an interview guide developed by the researchers, based on relevant literature. Findings from the thematic analysis showed five themes: (1) The hospital as a prison: a custody versus care dilemma, (2) quality of interactions between staff and service users, (3) quality of services, (4) staff qualities and (5) suggestions for achieving quality of care. A theoretical model drawing upon Donabedian Health Care Model for Evaluating quality of care and the Andersen Behavioural Model of Health Service Use is evident from the data. Structural aspects of care include staff experience and qualifications and key enablers around social and financial support, service users' health needs and status and the physical infrastructure and ward rules. These drive processes of care based upon robust rates of interaction between staff and service users and appear central to quality of mental health care in KSA. Quality of mental health care in KSA is manifested by a therapeutic ethos with a high degree of interaction between professional carers and service users, with the former being highly educated, competent, compassionate, with a high degree of self-awareness, and specialized in mental health. We have uncovered elements of Fanon and Azoulay's 'Cultural Originality' as well as contemporary examples of Goffman's mortification of the self. [Abstract copyright: © 2020 The Authors.

Exploring the structural relationship between interviewer and self-rated affective symptoms in Huntington’s disease

This study explores the structural relationship between self-report and interview measures of affect in Huntington’s disease. The findings suggest continued use of both to recognize the multidimensionality within a single common consideration of distress

Field dependence of the vortex core size in a multi-band superconductor

The magnetic field dependence of the vortex core size in the multi-band superconductor NbSe2 has been determined from muon spin rotation measurements. The spatially extended nature of the quasiparticle core states associated with the smaller gap leads to a rapid field-induced shrinkage of the core size at low fields, while the more tightly bound nature of the states associated with the larger gap leads to a field-independent core size for fields greater than 4 kOe. A simple model is proposed for the density of delocalized core states that establishes a direct relationship between the field-induced reduction of the vortex core size and the corresponding enhancement of the electronic thermal conductivity. We show that this model accurately describes both NbSe2 and the single-band superconductor V3Si.Comment: 4 pages, 4 figures. Version accepted for publication in Physical Review Letter

Looming struggles over technology for border control

New technologies under development, capable of inflicting pain on masses of people, could be used for border control against asylum seekers. Implementation might be rationalized by the threat of mass migration due to climate change, nuclear disaster or exaggerated fears of refugees created by governments. We focus on taser anti-personnel mines, suggesting both technological countermeasures and ways of making the use of such technology politically counterproductive. We also outline several other types of ‘non-lethal’ technology that could be used for border control and raise human rights concerns: high-powered microwaves, armed robots, wireless tasers, acoustic devices/vortex rings, ionizing and pulsed energy lasers, chemical calmatives, convulsants, bioregulators and malodurants. Whether all these possible border technologies will be implemented is a matter for speculation, but their serious human rights implications warrant advance scrutiny

Mitigating the impact of flip angle and orientation dependence in single compartment R2* estimates via 2-pool modeling

Purpose: The effective transverse relaxation rate ( R∗2 ) is influenced by biological features that make it a useful means of probing brain microstructure. However, confounding factors such as dependence on flip angle (α) and fiber orientation with respect to the main field ( θ ) complicate interpretation. The α- and θ -dependence stem from the existence of multiple sub-voxel micro-environments (e.g., myelin and non-myelin water compartments). Ordinarily, it is challenging to quantify these sub-compartments; therefore, neuroscientific studies commonly make the simplifying assumption of a mono-exponential decay obtaining a single R∗2 estimate per voxel. In this work, we investigated how the multi-compartment nature of tissue microstructure affects single compartment R∗2 estimates. Methods: We used 2-pool (myelin and non-myelin water) simulations to characterize the bias in single compartment R∗2 estimates. Based on our numeric observations, we introduced a linear model that partitions R∗2 into α-dependent and α-independent components and validated this in vivo at 7T. We investigated the dependence of both components on the sub-compartment properties and assessed their robustness, orientation dependence, and reproducibility empirically. Results: R∗2 increased with myelin water fraction and residency time leading to a linear dependence on α. We observed excellent agreement between our numeric and empirical results. Furthermore, the α-independent component of the proposed linear model was robust to the choice of α and reduced dependence on fiber orientation, although it suffered from marginally higher noise sensitivity. Conclusion: We have demonstrated and validated a simple approach that mitigates flip angle and orientation biases in single-compartment R∗2 estimates

Methane Production Pathway Regulated Proximally by Substrate Availability and Distally by Temperature in a High-Latitude Mire Complex

Projected 21st century changes in high-latitude climate are expected to have significant impacts on permafrost thaw, which could cause substantial increases in emissions to the atmosphere of carbon dioxide (CO2) and methane (CH4, which has a global warming potential 28 times larger than CO2 over a 100-year horizon). However, predicted CH4 emission rates are very uncertain due to difficulties in modeling complex interactions among hydrological, thermal, biogeochemical, and plant processes. Methanogenic production pathways (i.e., acetoclastic [AM] and hydrogenotrophic [HM]) and the magnitude of CH4 emissions may both change as permafrost thaws, but a mechanistic analysis of controls on such shifts in CH4 dynamics is lacking. In this study, we reproduced observed shifts in CH4 emissions and production pathways with a comprehensive biogeochemical model (ecosys) at the Stordalen Mire in subarctic Sweden. Our results demonstrate that soil temperature changes differently affect AM and HM substrate availability, which regulates magnitudes of AM, HM, and thereby net CH4 emissions. We predict very large landscape-scale, vertical, and temporal variations in the modeled HM fraction, highlighting that measurement strategies for metrics that compare CH4 production pathways could benefit from model informed scale of temporal and spatial variance. Finally, our findings suggest that the warming and wetting trends projected in northern peatlands could enhance peatland AM fraction and CH4 emissions even without further permafrost degradation

Codes of ethics content: UK and Australian corporations

Purpose This study aims to compare the content of the codes of ethics of the top 50 corporations in the UK and Australia. Design/methodology/approach The code of each of the 50 top companies listed on the London Stock Exchange and the 50 top companies listed on the Australian Stock Exchange based on market capitalization was read against an updated version of a previous code content classification system. Findings This research provides valuable insights into the similarities and differences that exist between the expected ethical standards in corporations based in two historically linked and culturally related countries: corporate approaches that are worthy of comment. Research limitations/implications This paper does provide a sound basis for further investigation and cross-country comparisons of corporate codes of ethics. Practical implications The instrument used for classifying code content gives an insight into the top companies operating in the UK and Australia and what they consider important to cover within a code of ethics. Social implications In light of increasing societal expectations of corporate ethical standards, this research study offers improved understanding of/insight into the development of codes of ethics as a means to guide organizational behaviours/conduct. Originality/value This study proposes a contemporary instrument for the analysis of codes of ethics that has built upon the work of others over the past 30 years
