The role of extraversion and neuroticism for experiencing stress during the third wave of the COVID-19 pandemic
Authors: Bellingtier Jennifer A. , Mund Marcus , Wrzus Cornelia 
Published: December 2021

AbstractAlthough long postulated, it has been scarcely researched how personality traits play out differently in distinct situations. We examined if Neuroticism and Extraversion, personality traits known to moderate stress processes, function differently in highly stressful situations requiring reduced social contact, that is, the COVID-19 pandemic. Based on past findings, we expected neuroticism to be associated with exacerbated perceptions of stress. In contrast to past findings, we expected extraversion, which usually ameliorates stress, to be associated with intensified perceptions of stress, especially in regard to the sociability facet. During the third wave of the COVID-19 pandemic in Germany, one-hundred-thirty adults (age M = 21.7 years) reported on their personality traits including their facets with the BFI-2, COVID-19-related stressors, and their perceived stress during the last month (using the PSS). Findings indicated that neuroticism was associated with higher perceived stress regardless of the COVID-19-related stressors experienced. Facet level analysis revealed differences for anxiety, depression, and volatility. Importantly, trait extraversion was unassociated with stress experiences, whereas specifically the facet of sociability was associated with higher perceived stress. Also, the facets of assertiveness and energy both moderated the relationship between COVID-19-related stressors and perceived stress. In line with the transactional theory of stress, our findings indicate that perceptions of stress were best understood by looking at the interaction of environmental stressors and personality differences. Furthermore, the study substantiates that facets of personality traits offer unique information beyond broad traits in specific contexts.
Noise-immune image blur detection via sequency spectrum truncation

Published: December 2021

AbstractBlur detection is aimed to differentiate the blurry and sharp regions from a given image. This task has attracted much attention in recent years due to its importance in computer vision with the integration of image processing and artificial intelligence. However, blur detection still suffers from problems such as the oversensitivity to image noise and the difficulty in cost–benefit balance. To deal with these issues, we propose an accurate and efficient blur detection method, which is concise in architecture and robust against noise. First, we develop a sequency spectrum-based blur metric to estimate the blurriness of each pixel by integrating a re-blur scheme and the Walsh transform. Meanwhile, to eliminate the noise interference, we propose an adaptive sequency spectrum truncation strategy by which we can obtain an accurate blur map even in noise-polluted cases. Finally, a multi-scale fusion segmentation framework is designed to extract the blur region based on the clustering-guided region growth. Experimental results on benchmark datasets demonstrate that the proposed method achieves state-of-the-art performance and the best balance between cost and benefit. It offers an average F1 score of 0.887, MAE of 0.101, detecting time of 0.7 s, and training time of 0.5 s. Especially for noise-polluted blurry images, the proposed method achieves the F1 score of 0.887 and MAE of 0.101, which significantly surpasses other competitive approaches. Our method yields a cost–benefit advantage and noise immunity that has great application prospect in complex sensing environment.
Blind spots in AI ethics
Authors: Hagendorff Thilo 
Published: December 2021

AbstractThis paper critically discusses blind spots in AI ethics. AI ethics discourses typically stick to a certain set of topics concerning principles evolving mainly around explainability, fairness, and privacy. All these principles can be framed in a way that enables their operationalization by technical means. However, this requires stripping down the multidimensionality of very complex social constructs to something that is idealized, measurable, and calculable. Consequently, rather conservative, mainstream notions of the mentioned principles are conveyed, whereas critical research, alternative perspectives, and non-ideal approaches are largely neglected. Hence, one part of the paper considers specific blind spots regarding the very topics AI ethics focusses on. The other part, then, critically discusses blind spots regarding to topics that hold significant ethical importance but are hardly or not discussed at all in AI ethics. Here, the paper focuses on negative externalities of AI systems, exemplarily discussing the casualization of clickwork, AI ethics’ strict anthropocentrism, and AI’s environmental impact. Ultimately, the paper is intended to be a critical commentary on the ongoing development of the field of AI ethics. It makes the case for a rediscovery of the strength of ethics in the AI field, namely its sensitivity to suffering and harms that are caused by and connected to AI technologies.

Authors: Thambiliyagodage Charitha , Wijesekera Ramanee , Bakker Martin G. 
Published: December 2021

AbstractNaturally available ilmenite mineral is being used as a starting material to produce titanium based products that have wide applications. Transformation of ilmenite to different titanium based materials by strong and weak acid, and base digestion, is discussed. Effects of temperature, concentration of acid/base, reaction time on dissolution of ilmenite are extensively reviewed. Characterization of the starting materials, intermediates and the products by x-ray diffraction, thermogravimetry, brunauer–emmett–teller surface area analysis, and scanning electron microscopy are presented. Further, advantages and disadvantages associated with the digestion methods are discussed.

Published: December 2021

ABSTRACT

Background
Previous studies have suggested that sexual function may be compromised in women born with differences of sex development (DSD) or early loss of gonadal function.

Aim
To describe sexual function and sexual wellbeing in women with complete androgen insensitivity syndrome (CAIS), complete gonadal dysgenesis (GD) and premature ovarian insufficiency (POI) in relation to gynecological measures and in comparison with unaffected women.

Methods
A cross sectional study including 20 women with CAIS, 8 women with 46,XY GD, 8 women with 46,XX GD, 21 women with POI, and 62 population-derived controls. Study participants underwent gynecological examination for anatomical measurements and evaluation of tactile sensitivity. They responded to the validated Sexual Activity Log (SAL), Profile of Female Sexual Function (PFSF), and the Personal Distress Scale (PDS).

Results
The women with CAIS, XY GD, XX GD and POI showed overall satisfying sexual function in comparison to unaffected age-matched population female controls with a median of 1 to 2 satisfying sexual episodes per week among both the patients and the controls depending on available partner. Women with CAIS had shorter vagina and smaller clitoris and women with XY GD had a significantly shallower vagina in comparison to controls. Clitoral width was also significantly smaller among women with XX GD compared to controls. However, results showed overall good genital touch sensitivity with no significant differences between groups.

Clinical Implications
Women with DSD or POI can be informed on overall satisfactory sexual function and normal genital touch sensitivity.

Strengths & Limitations
The strength is the use of age-matched population-based controls to these rare conditions of DSD and POI. Limitations are the nonresponder rate of recruited controls, as well as the small groups of women with DSD.

Conclusion
Women with differences of sex development or early loss of gonadal function show overall good sexual well-being, however clinicians have to make efforts to optimize caretaking and treatment to ensure good sexual quality of life for all patients.

Abstract

Background:
Baseline assessment of standard precaution relating to infection prevention and control (IPC) preparedness to fight health crisis within healthcare facilities at different levels and its associated factors in Bangladesh remains unknown.

Methods:
We analyzed the nationally representative Bangladesh health facility survey (BHFS) data conducted by the Ministry of Health and Family Welfare (MoHFW) during July–October 2017. We used the World Health Organization (WHO) Service Availability and Readiness Assessment (SARA) manual to determine the standard precautions related to the IPC readiness index. Using a conceptual framework and multivariable linear regression, we identified the factors associated with the readiness index.

Results:
We analyzed data for 1,524 surveyed healthcare facilities. On average, only 44% of the standard precaution elements were available in all facilities. Essential elements, such as guidelines for standard precautions (30%), hand-washing soap (29%), and pedal bins (38%), were not readily available in all facilities. The tuberculosis service area was least prepared, with 85% of elements required for standard precaution deficient in all facilities. Significantly lower readiness indexes were observed in the rural healthcare facilities (mean difference, −13.2), healthcare facilities administered by the MoHFW (mean difference, −7.8), and private facilities (mean difference, −10.1) compared to corresponding reference categories.

Conclusions:
Our study revealed a severe lack of standard precaution elements in most healthcare facilities, particularly in rural health centers. These data can provide a baseline from which to measure improvement in infection prevention and control (IPC) in these facilities and to identify areas of gaps for targeted interventions to improve IPC strategies that can improve the Bangladesh health system.
The commutative nonassociative algebra of metric curvature tensors
Authors: Fox Daniel J. F. 
Published: December 2021

AbstractThe space of tensors of metric curvature type on a Euclidean vector space carries a two-parameter family of orthogonally invariant commutative nonassociative multiplications invariant with respect to the symmetric bilinear form determined by the metric. For a particular choice of parameters these algebras recover the polarization of the quadratic map on metric curvature tensors that arises in the work of Hamilton on the Ricci flow. Here these algebras are studied as interesting examples of metrized commutative algebras and in low dimensions they are described concretely in terms of nonstandard commutative multiplications on self-adjoint endomorphisms. The algebra of curvature tensors on a 3-dimensional Euclidean vector space is shown isomorphic to an orthogonally invariant deformation of the standard Jordan product on$3 \times 3$symmetric matrices. This algebra is characterized up to isomorphism in terms of purely algebraic properties of its idempotents and the spectra of their multiplication operators. On a vector space of dimension at least 4, the subspace of Weyl (Ricci-flat) curvature tensors is a subalgebra for which the multiplication endomorphisms are trace-free and the Killing type trace-form is a multiple of the nondegenerate invariant metric. This subalgebra is simple when the Euclidean vector space has dimension greater than 4. In the presence of a compatible complex structure, the analogous result is obtained for the subalgebra of Kähler Weyl curvature tensors. It is shown that the anti-self-dual Weyl tensors on a 4-dimensional vector space form a simple 5-dimensional ideal isometrically isomorphic to the trace-free part of the Jordan product on trace-free$3 \times 3$symmetric matrices.
Drainage system and thermal structure of a High Arctic polythermal glacier: Waldemarbreen, western Svalbard

Published: December 2021

AbstractUnderstanding glacier drainage system behaviour and its response to increased meltwater production faces several challenges in the High Arctic because many glaciers are transitioning from polythermal to almost entirely cold thermal structures. We, therefore, used ground-penetrating radar data to investigate the thermal structure and drainage system of Waldemarbreen in Svalbard: a small High Arctic glacier believed to be undergoing thermal change. We found that Waldemarbreen retains up to 80 m of temperate ice in its upper reaches, but this thickness most likely is a relict from the Little Ice Age when greater ice volumes were insulated from winter cooling and caused greater driving stresses. Since then, negative mass balance and firn loss have prevented latent heat release and allowed near-surface ice temperatures to cool in winter, thus reducing the thickness of the temperate ice. Numerous reflectors that can be traced up-glacier are interpreted as englacial channels formed by hydrofracturing in the crevassed upper region of the glacier. The alternative cut and closure mechanism of conduit initiation only forms conduits in parts of the lower ablation area. Consequently, Waldemarbreen provides evidence that hydrofracturing at higher elevations can play a major role in englacial water drainage through cold ice.

Schmitt, Dicey, and the power and limits of referendums in the United Kingdom
Authors: Qvortrup Matt , Trueblood Leah 
Published: December 2021

AbstractCarl Schmitt and AV Dicey are two of history's most influential constitutional theorists, and they offer two of history's most influential accounts of referendums. In most respects, their approaches to referendums are in direct opposition to each other. On Schmitt's view, the purpose of referendums is to acclaim executive actors. On Dicey's view, the role of referendums is to constrain them. Despite disagreeing about whether referendums should acclaim or constrain the executive, Schmitt and Dicey agree that an agenda-setting role for representatives in referendums is inevitable. This paper argues that, in the UK context, if Schmitt and Dicey are right about the necessary agenda-setting power of representatives in referendums, then the accounts of referendums they each offer must be two sides of the same coin. Given the dominance of the executive over the legislature in the UK and the uncodified nature of the constitution, referendums are processes that necessarily both acclaim and limit the executive.
Ancient Bioi and Luke's Modifications of Matthew's Longer Discourses
Authors: Archer Joel 
Published: December 2021

AbstractMatthew's Gospel is known for its long, flowing discourses. The speeches in Luke, by contrast, are shorter and scattered throughout his narrative. Some believe this difference is evidence against the so-called ‘Farrer hypothesis’ – the view that Luke used both Mark and Matthew as sources. One response, however, is that Luke wanted to bring his speech lengths into closer conformity with the literary standards of Greco-Roman bioi. An analysis of seventeen representative bioi suggests that Matthew's speeches were exceptionally long for medium-sized biographies such as his own. This fact provides a plausible literary motivation for Luke to abbreviate Matthew's discourses.
Is Joshua a Type of Christ in Hebrews 4.8? An Assessment of the Referent of Ἰησοῦς
Authors: McKay J. Michael 
Published: December 2021

AbstractThe referent of Ἰησοῦς in Heb 4.8 is traditionally understood to refer to Joshua son of Nun and frequently as a type referring to Jesus the Christ. I will argue against this reading and, instead, maintain that the referent of Ἰησοῦς is Jesus. Two lines of evidence are provided. First, analysis of the context demonstrates that the ‘Joshua’ option disrupts the author's argument, and that understanding the referent to be Jesus clarifies the argument. Second, the use of thenomina sacraabbreviations to refer to Jesus in the earliest manuscripts demonstrates that they interpreted Ἰησοῦς as referring to Jesus.
Luke's Doublets and the Synoptic Problem
Authors: Grünstäudl Wolfgang 
Published: December 2021

AbstractThe Synoptic Gospels contain a significant number of so-called doublets, i.e. sayings or narratives which appear twice in one and the same Gospel. Since the nineteenth century these doublets have functioned as a classical argument in favour of the existence of Q. Focusing on treatments of Luke's doublets within the contemporary rivalry between the Farrer hypothesis and the two-document hypothesis, the present article contributes to a not-Q-biased discussion of the evidence. While adherents of the two-document hypothesis should not overestimate the force of doublet-based arguments, defenders of the Farrer hypothesis should pay greater attention to the creation and elimination of doublets as part of Luke's alleged redactional activity.
Predicting short-term suicidal thoughts in adolescents using machine learning: developing decision tools to identify daily level risk after hospitalization

Published: December 2021

AbstractBackgroundMobile technology offers unique opportunities for monitoring short-term suicide risk in daily life. In this study of suicidal adolescent inpatients, theoretically informed risk factors were assessed daily following discharge to predict near-term suicidal ideation and inform decision algorithms for identifying elevations in daily level risk, with implications for real-time suicide-focused interventions.MethodsAdolescents (N = 78; 67.9% female) completed brief surveys texted daily for 4 weeks after discharge (n = 1621 observations). Using multi-level classification and regression trees (CARTSs) with repeated 5-fold cross-validation, we tested (a) a simple prediction model incorporating previous-day scores for each of 10 risk factors, and (b) a more complex model incorporating, for each of these factors, a time-varying person-specific mean over prior days together with deviation from that mean. Models also incorporated missingness and contextual (study week, day of the week) indicators. The outcome was the presence/absence of next-day suicidal ideation.ResultsThe best-performing model (cross-validated AUC = 0.86) was a complex model that included ideation duration, hopelessness, burdensomeness, and self-efficacy to refrain from suicidal action. An equivalent model that excluded ideation duration had acceptable overall performance (cross-validated AUC = 0.78). Models incorporating only previous-day scores, with and without ideation duration (cross-validated AUC of 0.82 and 0.75, respectively), showed relatively weaker performance.ConclusionsResults suggest that specific combinations of dynamic risk factors assessed in adolescents' daily life have promising utility in predicting next-day suicidal thoughts. Findings represent an important step in the development of decision tools identifying short-term risk as well as guiding timely interventions sensitive to proximal elevations in suicide risk in daily life.
Risk factors for loneliness among older people in a Nordic regional context – a longitudinal study

Published: December 2021

AbstractThe aim of this study was to examine the prevalence of loneliness among older people and to identify risk factors for loneliness in a Nordic regional context over a six-year period. Longitudinal data from the Gerontological Regional Database (GERDA) study of 4,269 older adults living in northern Sweden and western Finland, aged 65, 70, 75 and 80 at baseline in 2010, were analysed. Logistic regressions were used to analyse socio-demographic, social and health-related risk factors at baseline and changes in these for experiences of loneliness at follow-up. The results showed that most older adults (85%) did not experience loneliness at baseline or at follow-up in our study region. However, 3 per cent of the sample reported loneliness in both study years, indicating enduring and chronic loneliness. Analyses revealed that being widowed and becoming a widow/er as well as poor self-rated health at baseline and the onset of depression were risk factors for loneliness. Finally, the risk of loneliness was higher in older people living in Sweden. Further work is needed to explore changes and stability in loneliness as well as to increase our understanding of between-country differences in loneliness.
Towards a minimal conception of Transitional Justice
Authors: Gentile Valentina , Foster Megan 
Published: December 2021

AbstractTransitional Justice (TJ) focuses on the processes of dealing with the legacy of large-scale past abuses (in the aftermath of traumatic experiences such as war or authoritarianism) with the aim of fostering domestic justice and creating the basis for a sustainable peace. TJ however also entails the problem of how a torn society may be able to become a self-determining member of a just international order. This paper presents a minimal conception of TJ, which departs from Rawls' conception of normative stability of the international order, which suggests disentangling the two goals of fostering democracy within torn societies and TJ itself. The scope of TJ is therefore limited to enabling these societies to create minimal internal conditions for joining a just international order on equal footing. This paper makes an original contribution to two different debates, namely normative research on TJ, and post-Rawlsian literature in general. First, it provides a new direction for normative theorizing about TJ which takes both its domestic and international dimensions seriously into consideration. Second, it extends Rawls' political liberal outlook to an area where it is not usually understood to apply.
