‘Everyday Bordering’ in England, Sweden and Bulgaria: Social Work Decision-Making Processes When Working with Migrant Family Members
Authors: Walsh Julie , Khoo Evelyn , Nygren Karina 
Published: May 2021

AbstractThe global movement of people is a growing feature of contemporary life, and it is essential that professionals providing support services know how to best engage with migrant families. However, despite globalisation and the related processes of de-bordering, borders continue to remain significant and, in contemporary life, the ways in which immigration is controlled and surveilled—bureaucratically and symbolically—are multiple. The paper draws on data gathered in the immediate period following the so called 2015 European ‘migration crisis’ and examines whether and in what ways social workers in three European countries—Bulgaria, Sweden and England—enact bordering in their work with migrant family members. We apply the concept of ‘everyday bordering’ to the data set: whilst borders are traditionally physical and at the boundary between nation states, bordering practices increasingly permeate everyday life in bureaucratic and symbolic forms. Overall, the data show that everyday bordering affects social work practice in three ways: by social workers being required to engage in bordering as an everyday practice; by producing conditions that require social workers to negotiate borders; and in revealing aspects of symbolic everyday bordering. Our analyses shows that ‘everyday bordering’ practices are present in social work decision-making processes in each country, but the forms they take vary across contexts. Analysis also indicates that, in each country, social workers recognise the ways in which immigration control can impact on the families with whom they work but that they can also inadvertently contribute to the ‘othering’ of migrant populations.
Neuroendocrine neoplasms of the lung: a pathology update
Authors: Metovic Jasna , Barella Marco , Pelosi Giuseppe 
Published: May 2021

Summary
Purpose
Neuroendocrine tumors and neuroendocrine carcinomas in the lung are distinct and separate entities featuring neuroendocrine differentiation, for which an accurate classification is clinically warranted.

Materials and methods
Three perspectives were addressed: (i) diagnostic tools, with the terminology to be used in either resection specimen or small-sized material; (ii) the so-called carcinoid tumors with elevated proliferation rates (mitotic and/or Ki-67 activity); (iii) predictive biomarkers based on immunohistochemical characterization.

Results
We herein provide a pathology update on lung neuroendocrine neoplasm classification that will appear in the forthcoming 5th edition of the WHO Blue Book, including a short discussion about biomarkers, which are presently given full consideration in clinical practice.

Conclusion
The WHO classification on lung neuroendocrine neoplasms is the cornerstone to provide the best clinical management of patients and is the starting point for any investigative insight.
Implementing the National Quality Standard in schools: leadership that motivates improvement initiatives through psychological ownership
Authors: Kirk Gillian , Barblett Lennie 
Published: May 2021

AbstractFrom 2016, all Western Australian schools were mandated to implement the National Quality Standard (NQS) in Kindergarten through to Year 2. Over the first year of implementation, this mandate had varying degrees of success in adoption. This study examined four schools which were identified as having implemented the NQS. A qualitative methodology was employed to examine those factors that supported implementation. A key finding was the integral role played by distributed leadership in adopting new initiatives. Using Activity Theory to conceptualise the data, it was found that psychological ownership was a key factor in enabling distributed leadership. Ownership was enabled when community differences were acknowledged, and time was given for the NQS tool to be reassessed and reconfigured as one’s own. Once staff had psychological ownership, they were more likely to support implementation of the NQS. This study has implications for leaders and those implementing the NQS or other initiatives in schools.
„Wenn ich lerne, dann werde ich auch Erfolg haben später“ – Kinder als Akteure in Prozessen struktureller (Re‑)Produktion
Authors: Türkyilmaz Aytüre 
Published: May 2021

ZusammenfassungDie Frage nach den Ursachen und Akteuren ungleicher Bildungsverläufe ist seit Jahrzehnten ein zentrales Thema des wissenschaftlichen Bildungsdiskurses. Dabei wird vor allem auf das Handeln der Lehrkräfte und der Eltern, also der erwachsenen Akteure, fokussiert, während weitgehend unberücksichtigt bleibt, wie die Kinder über ihr Handeln an diesem Geschehen beteiligt sind. Auf Basis qualitativer Längsschnittdaten zu Schüler/innenkarrieren untersucht der vorliegende Beitrag, inwiefern Kinder in Interaktionen mit Lehrkräften und Eltern eigene Handlungslinien realisieren können und wie damit ungleiche Herkunftsbedingungen in Bildungsvor- oder -nachteile übersetzt oder modifiziert werden. Die Ergebnisse zeigen, dass die Kinder aktiv am Zustandekommen ungleicher Bildungswege beteiligt sind – je nachdem, wie sie mit den Erwartungen der Erwachsenen in Familie und Schule umgehen und wie sie sich zur Zukunft positionieren. Die Studie liefert auch Einsichten dazu, wo diese Einflussnahme durch die Kinder auf strukturelle Grenzen stößt; dabei wird deutlich, wie die soziale Herkunft der Kinder in diesem Interaktionsgeflecht bedeutsam wird.

Abstract
Background
Physiological focal radiopharmaceutical uptake in the head and uncinate process of the pancreas may be seen on somatostatin receptor-based PET/CT and might lead to false-positive results for neuroendocrine tumours (NETs). We aimed to perform a systematic review and a meta-analysis about the prevalence of this finding.

Methods
We performed a comprehensive computer literature search across several databases until July 2020. Pooled prevalence of physiological focal uptake on somatostatin receptor-based PET/CT in the pancreas was calculated on a per-examination-based analysis and 95% confidence interval values (95% CI) were reported.

Results
Six studies (684 patients and 829 PET/CT scans) were included. The pooled prevalence of physiological uptake in the head and uncinate process of the pancreas on somatostatin receptor-based PET/CT imaging was 34% (95% CI 19.5–48.7%) with average SUVmax values ranging from 5 to 12.6. Heterogeneity was seen across the selected studies.

Conclusions
High radiopharmaceutical uptake in the head and uncinate process of the pancreas is frequent at somatostatin receptor-based PET/CT and it should be recognized by nuclear medicine physicians to prevent unnecessary additional investigations. In addition, next generation PET/CT tomographs might increase the prevalence of this finding.
Learning Analytics to Reveal Links Between Learning Design and Self-Regulated Learning

Published: May 2021

AbstractThe importance of learning design in education is widely acknowledged in the literature. Should learners make effective use of opportunities provided in a learning design, especially in online environments, previous studies have shown that they need to have strong skills for self-regulated learning (SRL). The literature, which reports the use of learning analytics (LA), shows that SRL skills are best exhibited in choices of learning tactics that are reflective of metacognitive control and monitoring. However, in spite of high significance for evaluation of learning experience, the link between learning design and learning tactics has been under-explored. In order to fill this gap, this paper proposes a novel learning analytic method that combines three data analytic techniques, including a cluster analysis, a process mining technique, and an epistemic network analysis. The proposed method was applied to a dataset collected in a massive open online course (MOOC) on teaching in flipped classrooms which was offered on a Chinese MOOC platform to pre- and in-service teachers. The results showed that the application of the approach detected four learning tactics (Search oriented, Content and assessment oriented, Content oriented and Assessment oriented) which were used by MOOC learners. The analysis of tactics’ usage across learning sessions revealed that learners from different performance groups had different priorities. The study also showed that learning tactics shaped by instructional cues were embedded in different units of study in MOOC. The learners from a high-performance group showed a high level of regulation through strong alignment of the choices of learning tactics with tasks provided in the learning design. The paper also provides a discussion about implications of research and practice.

Published: May 2021

AbstractThe increasing data scales in today’s business sectors coupled with the necessity of risk management raise the importance of business intelligence tools as an integrated solution for the insurance industry. These tools have mostly been used to achieve effective risk management. Although methods of risk management in the insurance industry have been proposed many years ago, the research effort has primarily been focused on predictive analyses. This study aimed to investigate the role of business intelligence as a solution to illustrate its potential in risk management particularly for decision-makers in agricultural insurance. We hypothesized that this would make a preferable decision in uncertain conditions. Sample data from the online transaction process system of Iran agricultural insurance fund were preprocessed in SQL server. Multidimensional online analytical processing architecture was analyzed using Targit business intelligence tool. Our results identified financial risks that lead to a framework of controlling risk based on business intelligence in the agricultural insurance fund.
Races, disease symptoms and genetic variability in Pyrenophora tritici-repentis isolates from Oklahoma that cause tan spot of winter wheat

AbstractIn recent years, tan spot of wheat caused by the fungus Pyrenophora tritici-repentis has become more prevalent in Oklahoma. Experiments were conducted to investigate the race structure, disease symptoms and genetic variability in P. tritici-repentis isolates collected from winter wheat over three decades. Race determination was conducted for 16 isolates based on expression of necrosis and/or chlorosis produced on wheat differentials. Variability in disease symptoms expressed by 12 isolates was determined on 13 hard red winter wheat cultivars grown in Oklahoma. In addition, genetic variability among 17 isolates was determined using amplified fragment length polymorphism-polymerase chain reaction (AFLP-PCR). All isolates except one (El Reno) were classified as race 1. Isolates varied widely in producing necrosis and/or chlorosis symptoms on wheat cultivars, but necrosis with a chlorotic halo was predominant (56.4%). AFLP-PCR analysis using 13 primer pairs produced a total of 494 alleles of which 285 were polymorphic. The overall genetic diversity among the isolates was 25.2%. Genetic relationships based on cluster analysis and principal component analysis showed only minor differences between isolates, and isolates did not form tight clusters or groups. The isolates of P. tritici-repentis were predominantly race 1; however, they produced a range of tan spot symptoms on wheat cultivars. The lack of distinct genetic grouping by the AFLP marker study indicates that the isolates used in this study likely originated from a single lineage.
Optogenetic tools controlled by ultraviolet-B light
Authors: Ouyang Xinhao , Ren Hui , Huang Xi 
Published: May 2021

AbstractDecades of genetic, molecular and biochemical studies in plants have provided foundational knowledge about light sensory proteins and led to their application in synthetic biology. Optogenetic tools take advantage of the light switchable activity of plant photoreceptors to control intracellular signaling pathways. The recent discovery of the UV-B photoreceptor UV RESISTANCE LOCUS 8 in the model plant Arabidopsis thaliana opens up new avenues for light-controllable methodologies. In this review, we discuss current developments in optogenetic control by UV-B light and its signaling components, as well as rational considerations in the design and applications of UV-B-based optogenetic tools.

Abstract
This article describes the manufacturing of silicon carbide composites with the addition of quasi-two-dimensional titanium carbide Ti3C2, known as MXene. The composites were obtained by the powder metallurgy technique, consolidated with the use of the Spark Plasma Sintering method at 1900 °C and dwelled for 30 min. The influence of the Ti3C2 MXene addition on the microstructure and mechanical properties of the composites was investigated. The structure of the MXene phase after the sintering process was also analyzed. The results showed a significant increase (almost 50%) of fracture toughness for composites with the addition of 0.2 wt% Ti3C2 MXene. In turn, the highest hardness, 23.2 GPa, was noted for the composite with the addition of the 1.5 wt% Ti3C2 MXene phase. This was an increase of over 10% in comparison to the reference sample. The analysis of chemical composition and observations using a transmission electron microscope showed that the Ti3C2 MXene phase oxidizes during sintering, resulting in the formation of crystalline, highly defected, disordered graphite structures. The presence of these structures in the microstructure, similarly to graphene, significantly affects the hardness and fracture toughness of silicon carbide.

ABSTRACTIntroductionAlthough early sexual intercourse may be associated with increased depressive symptoms, little research has examined whether first intercourse in late adolescence is associated with changes in mental health.MethodsThis paper uses 3 years of longitudinal data from previously sexually abstinent late adolescent students at a large state university in the northeastern United States (N = 144, 53.5% male, M age = 18.5 years old, 47.2% White, 26.4% Asian/Hawaiian/Pacific Islander, 20.1% Hispanic/Latino, 18.1% Black/African American) to examine whether levels of psychological distress changed after first intercourse.ResultsStudents’ distress decreased after first intercourse, although this effect was only significant two or more semesters after first intercourse. There were no gender differences in these associations.ConclusionsFindings suggest first intercourse was, on average, associated with decreased psychological distress for both male and female late adolescents.
E. coli versus Non-E. coli Urinary Tract Infections in Children
Authors: Al Nafeesah Abdullah , Al Fakeeh Khaled , Chishti Syed , Hameed Tahir 
Published: May 2021

Background:
While Escherichia coli (E. coli) is the most common uropathogen implicated in urinary tract infections (UTIs) in children, some studies have found that there are different characteristics between different uropathogens in children. The aim of this study was to compare E. coli and non-E. coli UTIs in children with respect to their demographic data, predisposing factors, and imaging results.

Methodology:
A retrospective chart review was done in children during their first admission with urine culture confirmed UTI in a tertiary care center. We divided patients into E. coli and non-E. coli groups according to urine culture results.

Results:
Out of 202 children with their first admission for a culture-proven UTI, pathogens other than E. coli accounted for 24.3% of UTIs. Klebsiella pneumoniae was the most common non-E. coli pathogen, followed by Pseudomonas aeruginosa and Enterococcus species. Non-E. coli UTIs were significantly more common in male subjects, younger children, and children with a past history of UTI or who had received antibiotics prior to admission. In addition, higher rates of abnormalities on renal ultrasound and VCUG were found with non-E. coli organisms.

Conclusion:
There is a significant difference in demographic and imaging findings in children with non-E. coli UTIs. These findings may impact the work-up and treatment of UTIs in the pediatric population.
La justice et la non-représentation au carrefour de la localisation sociale
Authors: Bernheim Emmanuelle , Noreau Pierre , Bahary-Dionne Alexandra 
Published: May 2021

RésuméLa présence accrue de justiciables non représenté·e·s devant les tribunaux est régulièrement attribuée à un manque de confiance envers le système judiciaire, notamment à l’égard des avocat·e·s. Agir seul·e devant les tribunaux serait donc un choix délibéré. Un sondage réalisé dans la population générale au Québec permet de démontrer au contraire que la grande majorité des citoyen·ne·s redoutent de faire face seul·e·s à la justice et souhaitent avoir accès aux services d’un·e professionnel·le du droit pour les représenter. Il permet aussi d’établir des liens entre certaines composantes de la localisation sociale des répondant·e·s – âge, condition socioéconomique, scolarité et genre – et leur opinion sur le système de justice et la non-représentation. Il faut en conclure que le rapport au droit et à la justice est la conséquence directe de structures sociales dont il faut tenir compte dans la compréhension de la réalité de la non-représentation.

AbstractWe prove a necessary and sufficient condition for isogenous elliptic curves based on the algebraic dependence ofp-adic elliptic functions. As a consequence, we give a short proof of thep-adic analogue of Schneider’s theorem on the linear independence ofp-adic elliptic logarithms of algebraic points on two nonisogenous elliptic curves defined over the field of algebraic numbers.
Maternal perception, concern and dissatisfaction with child weight and their association with feeding practices in the Generation XXI birth cohort
Authors: Costa Alexandra , Hetherington Marion M. , Oliveira Andreia 
Published: May 2021

AbstractWhat a mother thinks about her child’s weight status might influence what and how she feeds her child. We examined the association between maternal perception, concern and dissatisfaction with child weight alongside feeding practices. Participants were from the Generation XXI birth cohort (n= 3233). A validated version of the Child Feeding Questionnaire and the Overt/Covert Control scale were used. Associations were evaluated by linear regression models (βcoefficients and 95 % confidence intervals (95 % CI) with Bonferroni correction). Perceived underweight was associated with practices promoting food intake, such as higher pressure to eat at ages 4 and 7 years (β= 0·229; 95 % CI: 0·059, 0·398 andβ= 0·190; 95 % CI:0·005, 0·376, respectively) and lower restriction at age 4 (β= –0·175; 95 % CI: –0·0310, –0·039). At age 7, perceived overweight was associated with higher covert control (β= 0·203; 95 % CI: 0·029, 0·376). Mothers who were concerned about child weight reported higher restriction (β= 0·226; 95 % CI: 0·142, 0·310 at 4 years andβ= 0·261; 95 % CI: 0·169, 0·353 at 7 years) and covert control (β= 0·183; 95 % CI: 0·083, 0·282 at 4 years andβ= 0·171; 95 % CI: 0·073, 0·269 at 7 years). Maternal desire for a heavier child was associated with higher pressure to eat at both ages (β= 0·285; 95 % CI: 0·163, 0·406 andβ= 0·393; 95 % CI: 0·266, 0·520), while the desire for a thinner child was related to higher covert control at 7 years of age (β= 0·158; 95 % CI: 0·001, 0·316). Maternal perceptions and concern for child weight status are associated with feeding practices independently of actual weight status.

AbstractNegative interactions between people and crocodilians have increased worldwide, but in Mexico there have been few systematic reports and no rigorous evaluation of this problem. We compiled information on negative interactions between people and the spectacled caimanCaiman crocodilusand American crocodileCrocodylus acutusfrom the Worldwide Crocodilian Attack Database for 1993–2018, and we investigated interactions in greater depth, through interviews with people in La Encrucijada Biosphere Reserve. We examined the relationship between the occurrence of negative interactions between people andC. acutusand the species' nesting season and abundance, and presence records. In Mexico, the frequency of negative interactions increases when anthropogenic activities occur close to nesting sites (< 30 km) and during the nesting season (February–September). In La Encrucijada, following negative interactions with crocodiles, the local inhabitants killed 30 crocodiles measuring > 2.5 m long in 2011–2012. The frequency of negative human–crocodilian interactions was not correlated with the abundance of crocodilians but was correlated with the number of presence records of crocodiles. Strategies to minimize these interactions include warnings at nesting sites, increased monitoring of anthropogenic activities during the nesting season, and management of nests to prevent them being destroyed by people.
First step and last resort: One-Euro-Jobs after the reform
Authors: HARRER TAMARA , STOCKINGER BASTIAN 
Published: May 2021

AbstractJob creation programmes aim at increasing the employability of hard-to-place unemployed, and eventually integrating them into employment. Yet, previous evaluation studies have been pessimistic about their efficacy. For One-Euro-Jobs, a job creation programme for welfare benefit recipients in Germany, previous evaluations found unfavourable effects particularly for easier-to-place participants. Thus, in 2012 the legislator reformed the programme in order to target the hard-to-place more accurately. This study is the first post-reform evaluation of One-Euro-Jobs. We find that, although the programme is indeed better targeted than before, One-Euro-Jobs decrease participants’ employment chances within three years after programme entry. These outcomes are worse than those found for pre-reform participants. We cannot conclude with certainty whether the reform decreased the programme’s efficacy, but we identify channels through which the reform and other contemporaneous changes may have done so. These channels include changes in programme design features, changes in business-cycle conditions, and prolonged lock-in effects due to “programme careers”. To substantiate the latter explanation, we also provide novel evidence that One-Euro-Jobs seem to initiate programme careers.
