Published: September 2020

AbstractWe perform an analysis of public transport data from The Hague, the Netherlands, combined from three sources: static network information, automatic vehicles location and automated fare collection data. We highlight the effect of bunching swings, and show that this phenomenon can be extracted using unsupervised machine learning techniques, namely clustering. We also show the correlation between bunching rate and passenger load, and bunching probability patterns for working days and weekends. We present the approach for extracting isolated bunching swings formations (BSF) and show different cases of BSFs, some of which can persist for a considerable time. We applied our approach to the tram line 1 of The Hague, and computed and presented four different patterns of BSFs, which we name “high passenger load”, “whole route”, “evening, end of route”, “long duration”. We analyse each bunching swings formation type in detail.

AbstractCommon rye (Secale cereale L.) is one of the most important cereals in Europe. Nevertheless, its germplasm collections are among the least numerous compared with cereals. There are only about 27,000 Secale accessions in 70 gene banks around the world. Despite extensive research on the molecular characterization of genetic resources, only a fraction of this collection has been described. The main objective of the presented study was to perform genotypic and phenotypic characterization of an obsolete gene pool represented by 100 accessions originated from 28 countries around the world and preserved in the gene bank of the Polish Academy of Sciences Botanical Garden – Center for Biological Diversity Conservation in Powsin. Genetic analysis using simple sequence repeat markers showed that the obsolete gene pool is relatively large. This indicates that different sources of variability were used in breeding programs. However, the genetic variation is in no way related to the place of origin. Despite the great differences in the genetic make-up, the collection showed a broadly common phenotype. This could result in a low level of interest among breeders in the stored germplasm, undervalued as a source of important but not easily observable traits, e.g., high disease resistance, which was found in some accessions.
Addressing graduate capability through action research: a cross-disciplinary perspective in a New Zealand context
Authors: Zhang Qilong 
Published: September 2020

AbstractThe concept “graduate capability” has been created to respond to the trend that tertiary education graduates routinely encounter uncertainty and complexity. Adopting a multiple-site action research design, this study explored ways to address graduate capability across five disciplines in a New Zealand vocational education institution. Participants were 215 students and 21 teaching staff. Data collection included interviews, team meetings, and a variety of pedagogical documentation. Ethnographic content analysis was used for data analysis which generated five discipline-specific approaches to graduate capability intervention. Each approach included five dimensions: selection of focus capability items (FCIs) for intervention, composition of FCIs, strategies to address FCIs, impact of the intervention, and relationship between the intervention and the academic programme. This study not only helps the sampled programmes address graduate capability in an intentional and systematic way, but also offers an operational framework for designing capability intervention programmes in similar settings.
A Systematic Review of Bullying and Victimization Among Adolescents in India
Authors: Thakkar Niharika , van Geel Mitch , Vedder Paul 
Published: September 2020

AbstractThis study provides a systematic review of literature from India on traditional bullying and victimization among school-going adolescents. A search of bibliographic electronic databases PsycINFO, MEDLINE, ERIC, Web of Science, and PubMed was performed in May 2020. Thirty-seven studies were included in the review. For each study included, the following specifics were examined: (a) methodological characteristics, (b) prevalence estimates of bullying behavior, (c) forms of bullying, (d) risk factors, and (e) consequences of bullying. It was found that bullying happens in India, and some risk factors for bullying and victimization in India are typical to the Indian context. In addition, bullying in India is associated with adverse consequences for both the aggressor and the victim. Many studies on bullying from India should be interpreted cautiously because of problems with data collection processes, instrumentation, and presentation of the findings. Cross-cultural comparisons for prevalence estimates, and longitudinal studies to examine the direction of possible influence between bullying and its correlates need to be conducted, to cater to the large adolescent population of India.
Changes in positive and negative peer influences and depressive symptoms from adolescence to young adulthood
Authors: Homel Jacqueline , Thompson Kara , Leadbeater Bonnie 
Published: September 2020

ABSTRACTIntroductionPeers are believed to continue as prominent sources of influence for young adults. However, having peers who use alcohol and drugs is associated with depressive symptoms in young adults and research on the effects of having peers who model positive activities beyond adolescence is scarce.MethodIn this 10‐year study of 644 Canadian youth (52% female), we used multilevel modeling to examine the effects of within‐person and between‐person differences in the interplay of peer behaviours and changes in depressive symptoms between ages 14 and 25. Data were collected via face‐to‐face interviews and surveys for private topics.ResultsYouth with close friends who used drugs and alcohol consistently reported more depressive symptoms at each age, whereas having friends who engaged in positive activities was associated with fewer depressive symptoms, especially during adolescence. Moreover, at times when youth had more substance‐using peers than usual (within person variation), they also reported more symptoms.ConclusionsSubstance‐using peer contexts convey both short‐ and long‐term risks for depressive symptoms. However, the protective effects of having peers who are engaged in positive activities, while generally protective, may be reduced in young adulthood. It is possible that older youth withdraw from peers and activities as their depression worsens, and prosocial activities become less supervised by parents, more optional, and more expensive.
How others drive our sense of understanding of policies
Authors: RABB NATHANIEL , HAN JOHN J. , SLOMAN STEVEN A. 
Published: September 2020

AbstractFive experiments are reported to compare models of attitude formation about hot-button policy issues like climate change. In broad strokes, the deficit model states that incorrect opinions are a result of a lack of information, while the cultural cognition model states that opinions are formed to maximize congruence with the group that one affiliates with. The community of knowledge hypothesis takes an integrative position. It states that opinions are based on perceived knowledge, but that perceptions are partly determined by the knowledge that sits in the heads of others in the community. We use the fact that people's sense of understanding is affected by knowledge of others’ understanding to arbitrate among these views in the domain of public policy. In all experiments (N = 1767), we find that the contagious sense of understanding is nonpartisan and robust to experimental manipulations intended to eliminate it. While ideology clearly affects people's attitudes, sense of understanding does as well, but level of actual knowledge does not. And the extent to which people overestimate their own knowledge partly determines the extremity of their position. The pattern of results is most consistent with the community of knowledge hypothesis. Implications for climate policy are considered.

AbstractThe present study aimed to investigate nutritional programming of carbohydrate metabolism in Nile tilapia. Early nutritional intervention stimulus was achieved by feeding fry with high-protein/low-carbohydrate (HP/LC) or low-protein/high-carbohydrate (LP/HC) diet since first feeding for 4 weeks, and the effect of nutritional stimulus on carbohydrate and its related metabolism was evaluated through the adult stage. Our findings indicated that at week 1, LP/HC diet-fed fry had lower levels of mRNA for genes coding gluconeogenesis and amino acid catabolism and higher levels ofhk2 (P< 0⋅05). As expected, in adult tilapia, although LP/HC diet-fed fish had poorer growth (end of stimulus), the fish showed compensatory growth. There were permanent effects of early high-carbohydrate (HC) intake on several parameters, including (1) modulating hepatic composition, (2) increased muscle glycogen, (3) lower levels of enzymes involved in amino acid catabolism and (4) higher levels of glycolytic enzymes in glycolysis. Finally, HP/LC diet- and LP/HC diet-fed fish were challenged with different dietary carbohydrate levels. Irrespective of challenging diets, the early HC stimulus had significant effects on adult tilapia by (1) promoting utilisation of glucose, which had protein-sparing effects for better growth, (2) inducting lipogenesis and (3) decreasing amino acid catabolism. Taken together, for the first time, we demonstrated that early HC feeding was effective for positive nutritional programming of metabolism in Nile tilapia (an omnivorous fish). It led to the improvement of growth performance in adult fish associated with early feeding, which is linked to a better ability to use glucose, to induce lipogenesis, and to suppress amino acid catabolism.
MULTIDIMENSIONAL EXACT CLASSES, SMOOTH APPROXIMATION AND BOUNDED 4-TYPES
Authors: WOLF DANIEL 
Published: September 2020

AbstractIn connection with the work of Anscombe, Macpherson, Steinhorn and the present author in [1] we investigate the notion of a multidimensional exact class (R-mec), a special kind of multidimensional asymptotic class (R-mac) with measuring functions that yield the exact sizes of definable sets, not just approximations. We use results about smooth approximation [24] and Lie coordinatization [13] to prove the following result (Theorem 4.6.4), as conjectured by Macpherson: For any countable language$\mathcal {L}$and any positive integerdthe class$\mathcal {C}(\mathcal {L},d)$of all finite$\mathcal {L}$-structures with at mostd4-types is a polynomial exact class in$\mathcal {L}$, where a polynomial exact class is a multidimensional exact class with polynomial measuring functions.
Evidence that more than a third of Paleozoic articulate brachiopod genera (Strophomenata) lived infaunally
Authors: Stanley Steven M. 
Published: September 2020

AbstractThe Strophomenata, which includes two large orders, the Strophomenida and Productida, is the largest group of Paleozoic brachiopods. Nearly all uncemented strophomenatans possessed an unusual concave brachial valve. Most of these have been considered to have lived epifaunally, but had they rested on the seafloor, not only would they have faced intense predation, but their physical instability would have been fatal. I conclude that nearly all strophomenatans, like similar concavo-convex pectinid bivalves, lived infaunally by ejecting water to create a pit into which they descended, to be protected by sediment covering the concave valve. Strophomenatans have been discovered with this sediment preserved in place. If exhumed and turned upside down, a strophomenatan could have righted itself by squirting water. Many productides had anchoring spines, and some had hinge areas with stabilizing flanges. Small spines on the brachial valves of some productides served to trap disguising sediment. Evolutionary loss of hinge teeth within both the Strophomenida and Productida reduced the friction of valve clapping. Partly because of their slender shape, strophomenides were typically more vulnerable to exhumation than productides. Strophomenides also ejected water less effectively than productides and would have been less adept at righting themselves. The virtual disappearance of the strophomenides during the Devonian can be attributed to their vulnerability to intensifying benthic bulldozing and predation. The success of the productides during the late Paleozoic can be attributed to their relatively deep sequestration in the sediment and ability to right themselves and reburrow effectively when exhumed and overturned.
Stress-related cognitive style is related to volumetric change of the hippocampus and FK506 binding protein 5 polymorphism in post-traumatic stress disorder

Published: September 2020

AbstractBackgroundPatients with post-traumatic stress disorder (PTSD) show a different stress-related cognitive style compared with healthy controls (HC). The FK506 binding protein 5 gene (FKBP5), one of the PTSD known risk factors, is involved in the stress response through the hypothalamic-pituitary-adrenal axis and brain volumetric alterations. The present study aimed to uncover the neural correlates of stress-related cognitive styles through the analysis of the regional brain volumes and FKBP5 genotype in patients with PTSD compared with HC.MethodsIn this study, 51 patients with PTSD and 94 HC were assessed for stress-related cognitive styles, PTSD symptoms severity, and genotype of FKBP5 single nucleotide polymorphisms, and underwent T1-weighted structural magnetic resonance imaging. Diagnosis-by-genotype interaction for regional brain volumes was examined in 16 brain regions of interest.ResultsPatients with PTSD showed significantly higher levels of catastrophizing, ruminative response, and repression, and reduced distress aversion and positive reappraisal compared with HC (p < 0.001). Significant diagnosis-by-genotype interactions for regional brain volumes were observed for bilateral hippocampi and left frontal operculum. A significant positive correlation between the severity of the repression and left hippocampal volume was found in a subgroup of patients with PTSD with FKBP5 rs3800373 (AA genotype) or rs1360780 (CC genotype).ConclusionsThe present study showed the influences of FKBP5 genotype on the distorted cognitive styles in PTSD by measuring the volumetric alteration of hippocampal regions, providing a possible role of the hippocampus and left frontal operculum as significant neurobiological correlates of PTSD.

Published: September 2020

AbstractBackgroundWe investigated work-related exposure to stressful and traumatic events in police officers, including repeated exposure to traumatic materials, and predicted that ICD-11 complex PTSD (CPTSD) would be more prevalent than posttraumatic stress disorder (PTSD). The effects of demographic variables on exposure and PTSD were examined, along with whether specific types of exposure were uniquely associated with PTSD or CPTSD.MethodsAn online survey covering issues about trauma management, wellbeing and working conditions was disseminated via social media and official policing channels throughout the UK. In total, 10 401 serving police officers self-identified as having been exposed to traumatic events. Measurement of PTSD and CPTSD utilised the International Trauma Questionnaire.ResultsThe prevalence of PTSD was 8.0% and of CPTSD was 12.6%. All exposures were associated with PTSD and CPTSD in bivariate analyses. Logistic regression indicated that both disorders were more common in male officers, and were associated independently with frequent exposure to traumatic incidents and traumatic visual material, and with exposure to humiliating behaviours and sexual harassment, but not to verbal abuse, threats or physical violence. Compared to PTSD, CPTSD was associated with exposure to humiliating behaviours and sexual harassment, and also with lower rank and more years of service.ConclusionsCPTSD was more common than PTSD in police officers, and the data supported a cumulative burden model of CPTSD. The inclusion in DSM-5 Criterion A of work-related exposure to traumatic materials was validated for the first time. Levels of PTSD and CPTSD mandate enhanced occupational mental health services.

AbstractBackgroundBipolar disorder (BD) is a familial psychiatric disorder associated with frontotemporal and subcortical brain abnormalities. It is unclear whether such abnormalities are present in relatives without BD, and little is known about structural brain trajectories in those at risk.MethodNeuroimaging was conducted at baseline and at 2-year follow-up interval in 90 high-risk individuals with a first-degree BD relative (HR), and 56 participants with no family history of mental illness who could have non-BD diagnoses. All 146 subjects were aged 12–30 years at baseline. We examined longitudinal change in gray and white matter volume, cortical thickness, and surface area in the frontotemporal cortex and subcortical regions.ResultsCompared to controls, HR participants showed accelerated cortical thinning and volume reduction in right lateralised frontal regions, including the inferior frontal gyrus, lateral orbitofrontal cortex, frontal pole and rostral middle frontal gyrus. Independent of time, the HR group had greater cortical thickness in the left caudal anterior cingulate cortex, larger volume in the right medial orbitofrontal cortex and greater area of right accumbens, compared to controls. This pattern was evident even in those without the new onset of psychopathology during the inter-scan interval.ConclusionsThis study suggests that differences previously observed in BD are developing prior to the onset of the disorder. The pattern of pathological acceleration of cortical thinning is likely consistent with a disturbance of molecular mechanisms responsible for normal cortical thinning. We also demonstrate that neuroanatomical differences in HR individuals may be progressive in some regions and stable in others.
A Systematic Review of the Psychometric Properties of the Geriatric Anxiety Inventory
Authors: Champagne Alexandra , Landreville Philippe , Gosselin Patrick 
Published: September 2020

ABSTRACTThe Geriatric Anxiety Inventory (GAI) and its short form (GAI-SF) are self-reported scales used internationally to assess anxiety symptoms in older adults. In this study, we conducted the first critical comprehensive review of these scales’ psychometric properties. We rated the quality of 31 relevant studies with the COSMIN checklist. Both the GAI and GAI-SF showed adequate internal consistency and test-retest reliability. Convergent validity indices were highest with generalized anxiety measures; lowest with instruments relating to somatic symptoms. We detected substantial overlap with depression measures. While there was no consensus on the GAI’s factorial structure, we found the short version to be unidimensional. Although we found good sensitivity and specificity for detecting anxiety, cut-off scores varied. The GAI and GAI-SF are relevant instruments showing satisfactory psychometric properties; to broaden their use, however, some psychometric properties warrant closer examination. This review calls attention to weaknesses in the methodological quality of the studies.

Published: September 2020

AbstractDystonia is a movement disorder that can have a debilitating impact on motor functions and quality of life. There are 250,000 cases in the United States, most with childhood onset. Due to the limited effectiveness and side effects of available treatments, pediatric deep brain stimulation (pDBS) has emerged as an intervention for refractory dystonia. However, there is limited clinical and neuroethics research in this area of clinical practice. This paper examines whether it is ethically justified to offer pDBS to children with refractory dystonia. Given the favorable risk-benefit profile, it is concluded that offering pDBS is ethically justified for certain etiologies of dystonia, but it is less clear for others. In addition, various ethical and policy concerns are discussed, which need to be addressed to optimize the practice of offering pDBS for dystonia. Strategies are proposed to help address these concerns as pDBS continues to expand.
Psychiatric Interventions in Virtual Reality: Why We Need an Ethical Framework
Authors: MARLOTH MARIA , CHANDLER JENNIFER , VOGELEY KAI 
Published: September 2020

AbstractRecent improvements in virtual reality (VR) allow for the representation of authentic environments and multiple users in a shared complex virtual world in real time. These advances have fostered clinical applications including in psychiatry. However, although VR is already used in clinical settings to help people with mental disorders (e.g., exposure therapy), the related ethical issues require greater attention. Based on a thematic literature search the authors identified five themes that raise ethical concerns related to the clinical use of VR: (1) reality and its representation, (2) autonomy, (3) privacy, (4) self-diagnosis and self-treatment, and (5) expectation bias. Reality and its representation is a theme that lies at the heart of VR, but is also of specific significance in a clinical context when perceptions of reality are concerned, for example, during psychosis. Closely associated is the autonomy of VR users. Although autonomy is a much-considered topic in biomedical ethics, it has not been sufficiently discussed when it comes to applications of VR in psychiatry. In this review, the authors address the different themes and recommend the development of an ethical framework for the clinical use of VR.

Published: September 2020

AbstractThis paper analyzes in the use of virtual reality when used to induce full-body ownership in violent offenders in order to elicit empathetic feelings by allowing them to embody the virtual body of a victim of domestic abuse. The authors explore potentially harmful effects to individuals participating in this kind of therapy and question whether consent is fully informed. The paper concludes with guidelines for ethical research and rehabilitation using this innovative technology.
