Οι διαταραχές αυτιστικού φάσματος είναι νευροαναπτυξιακές διαταραχές, που επηρεάζουν τις κοινωνικές και επικοινωνιακές αλληλεπιδράσεις των ατόμων, προκαλώντας ταυτόχρονα και άκαμπτες συμπεριφορές τους προς το κοινωνικό τους περιβάλλον. Τα παιδιά με αυτισμό διακατέχονται από γνωστικές και συναισθηματικές δυσλειτουργίες, οι οποίες επηρεάζουν αρνητικά τις κοινωνικές τους σχέσεις. Δεν μπορούν να κατανοήσουν τις απόψεις των άλλων, να κατανοήσουν κοινωνικές και συναισθηματικές αναφορές, κι ως εκ τούτου δεν μπορούν να ελίσσονται στις κοινωνικές τους συναλλαγές. Οι αλληλεπιδράσεις, όμως, μεταξύ των ομηλίκων αποτελούν μια σημαντική κοινωνική εμπειρία για τα παιδιά και τους εφήβους, και συχνά οδηγούν σε σταθερές, αμοιβαίες και συναισθηματικές σχέσεις φιλίας. Έρευνες έχουν δείξει, ότι, παρόλο που τα παιδιά που ανήκουν στο φάσμα του αυτισμού παρουσιάζουν σοβαρές ελλείψεις στις κοινωνικές τους δεξιότητες, επιθυμούν τις κοινωνικές σχέσεις και αναγνωρίζουν περισσότερο συχνά το αίσθημα της μοναξιάς από ότι τα παιδιά τυπικής ανάπτυξης. Μέσω προσωπικών τους αναφορών, έχει επισημανθεί η σπουδαιότητα που έχουν οι κοινωνικές σχέσεις για τα ίδια. Ένα ποσοστό παιδιών με αυτισμό επιθυμούν ένα φίλο, αλλά αποφεύγουν τις σχέσεις με ομηλίκους τους, διότι μια τέτοιου είδους σχέση απαιτεί κοινά ενδιαφέροντα και κοινωνικές δεξιότητες που δεν κατέχουν. Λαμβάνοντας υπ΄όψιν τις έρευνες που επισημαίνουν την επιθυμία των παιδιών με αυτισμό να έχουν έναν φίλο, αλλά την αδυναμία τους να τον αποκτήσουν, λόγω των δυσλειτουργιών τους, αποτέλεσμα των διάχυτων αναπτυξιακών τους διαταραχών, η παρούσα μελέτη περίπτωσης αποσκοπεί στην βελτίωση των κοινωνικών σχέσεων ενός μαθητή με αυτισμό, της Β’ τάξης, ενός Δημοτικού σχολείου, τυπικής εκπαίδευσης. Η μέθοδος που πραγματοποιήθηκε είναι παρέμβαση με χρήση κοινωνικών ιστοριών. Έγινε κοινωνιομέτρηση με κοινωνιογράμματα, πριν και μετά την παρέμβαση, ώστε να υπολογισθεί η βελτίωση που θα σημειωθεί στον μαθητή. Συλλήβδην, η παρούσα μελέτη αποσκοπεί στην βελτίωση των κοινωνικών σχέσεων αυτού του αγοριού με τους ομηλίκους του, και εν συνεχεία, στην περαιτέρω βελτίωση της ποιότητας της ζωής του και της ψυχικής του υγείας, στο μέτρο όπου είναι αυτό εφικτό. Εν κατακλείδι, η χορήγηση της κοινωνικής ιστορίας και οι κλείδες παρατήρησης, που συμπληρώθηκαν κατά τη διάρκεια του διαλείμματος, κατέστησαν σαφές ότι υπήρξε βελτίωση των κοινωνικών σχέσεων του μαθητή. Συνιστάται εκ νέου έκθεση του μαθητή στην κοινωνική ιστορία, έως το τέλος της σχολικής χρονιάς, για να διαπιστωθεί εάν τα αποτελέσματα της παρέμβασης έχουν διάρκεια και αν όχι, ποιες τροποποιήσεις θα πρέπει να γίνουν στην παρέμβαση ώστε τα αποτελέσματα της να γίνουν διαρκή.

Το φαινόμενο του εκφοβισμού παιδιών από τους συμμαθητές τους στα σχολεία είναι τόσο παλιό όσο και η διαδικασία της σχολικής μάθησης. Είναι δε τόσο συνηθισμένο, ώστε πολλοί γονείς αλλά και δάσκαλοι θεωρούν αυτού του είδους την συμπεριφορά και εμπειρία ως εκ των ουκ άνευ της ενσωμάτωσης του παιδιού στην κοινότητα των συνομηλίκων τους.O σχολικός εκφοβισμός αποτελεί μια βίαιη και επιθετική συμπεριφορά, η οποία εντοπίζεται στα πλαίσια του σχολείου και έχει σοβαρές επιπτώσεις στην ψυχολογική και συναισθηματική κατάσταση του μαθητή καθώς επίσης και στην διαδικασία της μάθησης. Πρόκειται για τη σκόπιμη και επαναλαμβανόμενη βίαιη συμπεριφορά ενός μαθητή απέναντι σε έναν άλλον, η οποία έχει στόχο την επιβολή αλλά και την πρόκληση σωματικού ή ψυχικού πόνου. Συχνά τα παράπονα των παιδιών αντιμετωπίζονται από τους γονείς και τους άλλους ενήλικες (πχ. εκπαιδευτικοί) με αδιαφορία και με ειρωνικά σχόλια που στόχο έχουν να ελαχιστοποιήσουν την σημασία του συμβάντος. Αυτό το γεγονός είχε ως αποτέλεσμα να είναι πολλά τα παιδιά που καλούνται να υπομείνουν σιωπηλά αυτόν τον εφιάλτη. Για τον λόγο αυτό στην παρούσα εργασία ασχολούμαστε με τον εκφοβισμό ώστε να γίνει καλύτερη κατανόηση του φαινομένου, των αιτιών του αλλά και του τρόπου αντιμετώπισής του.

Objective: Diabetic foot ulcers (DFU) are often hard-to-heal, despite standard care. With such a complicated healing process, any advanced wound care to aid healing is recommended. Chitosan/collagen composite hydrogel materials have the potential to promote the regenerative process. In this study, the efficacy of a new collagen matrix dressing including chitosan/collagen hydrogel was compared with a standard dressing of saline-moistened gauze for wound healing in patients with a hard-to-heal neuropathic DFU. Method: This is an open labelled, randomised clinical trial. After conventional therapy consisting of debridement, infection control and offloading, patients were randomly allocated to receive either a collagen matrix dressing (the study group, receiving Tebaderm manufacturer) or a saline-moistened gauze dressing (control group) for wound care. The reduction in DFU size and the number of patients with complete healing were measured throughout the treatment and in follow-up. Results: A total of 61 patients with a neuropathic DFU were recruited. Average percentage reduction in DFU size at four weeks was greater in the study group compared with the control group (54.5% versus 38.8%, respectively). Rate of complete healing rate at 20-weeks' follow-up was significantly better in the study group than the control group (60% versus 35.5%, respectively). Conclusion: The collagen matrix dressing used in this study accelerated the healing process of patients with a hard-to-heal DFU. Further research may suggest the used of this dressing to shorten the length of time to achieve complete healing.

Objective: The aim of this systematic review was to examine the associations and relationship between commonly cited risk factors and the pathology of pressure ulcer (PU) development. Method: Using systematic review methodology, original research studies, prospective design and human studies written in English were included. The search was conducted in March 2018, using Ovid, Ovid EMBASE and CINAHL databases. Data were extracted using a pre-designed extraction tool and all included studies were quality appraised using the evidence-based librarianship critical appraisal. Results: A total of 382 records were identified, of which five met the inclusion criteria. The studies were conducted between 1994 and 2017. Most studies were conducted in hospital and geriatric wards. The mean sample size was 96±145.7 participants. Ischaemia, recovery of blood flow and pathological impact of pressure and shear was mainly found as the cited risk factor and PU aetiology. Conclusion: This review systematically analysed five papers exploring the relationship between risk factors for PU development and aetiology. It identified many risk factors and underlying pathological mechanisms that interact in the development of PU including ischaemia, stress, recovery of blood flow, tissue hypoxia and the pathological impact of pressure and shear. There are several pathways in which these pathological mechanisms contribute to PU development and identifying these could establish potential ways of preventing or treating the development of PU for patients.
Severe acute pancreatitis: eight fundamental steps revised according to the ‘PANCREAS’ acronym

Published: March 2020

Severe acute pancreatitis remains a life-threatening condition, responsible for many disorders of homeostasis and organ dysfunction. By means of a mnemonic ‘PANCREAS’, eight important steps in the management of severe acute pancreatitis are highlighted. These steps follow the principle of goal-directed therapy and should be borne in mind after diagnosis and during clinical treatment. The first step is perfusion: the goal is to reach a central venous pressure of 12–15mmHg, urinary output 0.5–1ml/kg/hour and inferior vena cava collapse index greater than 48%. Next is analgesia: multimodal, systemic and combined pharmacological agent and epidural block are possibilities. Third is nutrition: precocity, enteral feeding in gastric or post-pyloric position. Parenteral nutrition works best in difficult cases to achieve the individual total caloric value. Fourth is clinical: mild, moderate or severe pancreatitis according to the Atlanta criteria. Radiology is fifth: abdominal computed tomography on the fourth day for prognosis or to modify management. Endoscopy is sixth: endoscopic retrograde cholangiopancreatography (cholangitis, unpredicted clinical course and ascending jaundice); management of pancreatic fluid collection and ‘walled-off necrosis’. Antibiotics come next: infectious complications are common causes of morbidity. The only rational indication for antibiotics is documented pancreatic infection. The last step is surgery: the dogma is represented by the ‘three Ds’ (delay, drain, debride). The preferred method is a minimally invasive step-up approach, which allows for gradually more invasive procedures when the previous treatment fails.
Youth Documentary Academy: The social practices of filmmaking and media advocacy
Authors: Canella Gino 
Published: March 2020

Youth Documentary Academy (YDA) is a seven-week documentary workshop in Colorado Springs, Colorado. Through ethnographic research and collaborative filmmaking, I examine documentary production and exhibition as social practices that foster meaningful relationships between media makers and community organisations working for social justice. Between November 2016 and July 2018, I conducted 20 interviews with current and former YDA filmmakers, faculty and community organisers. Many YDA filmmakers produced films through first-person point-of-view testimonials, which explored intimate details of their lives and the issues facing their families and communities. Although this narrative style may individualise systemic injustices, I argue that the affective nature of filmmaking and film exhibition, and the partnerships that YDA developed with community organisations, helped youth realise an advocacy role. For filmmakers, the empathic dialogues that emerged at public screenings of YDA films illuminated the way media have the potential to foster solidarity.
High-quality net shape geometries from additively manufactured parts using closed-loop controlled ablation with ultrashort laser pulses
Authors: Holder Daniel , Leis Artur , Buser Matthias , Weber Rudolf , Graf Thomas 
Published: March 2020

Abstract
Additively manufactured parts typically deviate to some extent from the targeted net shape and exhibit high surface roughness due to the size of the powder grains that determines the minimum thickness of the individual slices and due to partially molten powder grains adhering on the surface. Optical coherence tomography (OCT)-based measurements and closed-loop controlled ablation with ultrashort laser pulses were utilized for the precise positioning of the LPBF-generated aluminum parts and for post-processing by selective laser ablation of the excessive material. As a result, high-quality net shape geometries were achieved with surface roughness, and deviation from the targeted net shape geometry reduced by 67% and 63%, respectively.
A Model of Inequality Aversion and Private Provision of Public Goods
Authors: Yokoo Hide-Fumi 
Published: March 2020

AbstractI develop a model of inequality aversion and public goods that allows the marginal rate of substitution to be variable. As a theoretical foundation, utility function of the standard public goods model is nested in the Fehr-Schmidt model. An individual’s contribution function for a public good is derived by solving the problem of kinky preference and examining both interior and corner solutions. Results show that the derived contribution function is not monotonic with respect to the other individual’s provision. Thus, the model can be used to explain empirical evidence for the effect of social comparison on public-good provision.

Abstract

Background
This is a second part of report on the IFCC global multicenter study conducted in Saudi Arabia to derive reference intervals (RIs) for 20 immunoassay analytes including five tumor makers, five reproductive, seven other hormones and three vitamins.

Methods
A total of 826 apparently healthy individuals aged ≥18 years were recruited in three clinical laboratories located in western, central and eastern Saudi Arabia using the protocol specified for the global study. All serum specimens were measured using Abbott, Architect analyzers. Multiple regression analysis (MRA) was performed to explore sources of variation of each analyte: age, body mass index (BMI), physical exercise and smoking. The magnitude of variation of reference values (RVs) attributable to sex, age and region was calculated by ANOVA as a standard deviation ratio (SDR). RIs were derived by the parametric (P) method.

Results
MRA revealed that region, smoking and exercise were not relevant sources of variation for any analyte. Based on SDR and actual between-sex differences in upper limits (ULs), we chose to partition RIs by sex for all analytes except for α-fetoprotein and parathyroid hormone (PTH). Age-specific RIs were required in females for ferritin, estradiol, progesterone, testosterone, follitropin, luteotropin and prolactin (PRL). With prominent BMI-related increase, RIs for insulin and C-peptide were derived after excluding individuals with BMI > 32 kg/m2. Individuals taking vitamin D supplements were excluded in deriving RIs for vitamin D and PTH.

Conclusions
RIs of major immunoassay analytes specific for Saudi Arabians were established in careful consideration of various biological sources of variation.
Syntactico-semantic realizations of pronouns in the English transitive construction: A corpus-based analysis
Authors: Hwang Haerim 
Published: March 2020

AbstractPronouns serve as early linguistic cues for the acquisition of the English transitive construction (TC), but previous research has been limited to first language (L1) settings. This study focuses on TC input in the English as a foreign language (EFL) context, investigating syntactico-semantic differences in realizations of TC arguments, particularly pronouns, between L1 parental input and Korean EFL input. To this end, four corpora were created by collecting spoken data from L1-English parents talking to their children, L1-Korean EFL teachers, L1-English EFL teachers, and auditory EFL textbooks. From these corpora, transitive clauses were extracted so that their arguments could be categorized. Mixed-effects negative binomial regression analyses and hierarchical cluster analyses (preceded by principal component analyses) showed that in the realization of TC arguments, Korean EFL input differs syntactically and semantically from L1-English parental input, both for the subjects and objects of TCs. The syntactic difference was particularly pronounced for objects, where fewer pronouns were observed in the EFL input than in the L1-English parental input. Semantically, co-occurrence regularities between transitive verbs and arguments were identified only in the L1-English input and not in the EFL input. Pedagogical implications of the findings are also discussed.
Individuality in syntactic variation: An investigation of the seventeenth-century gerund alternation
Authors: Fonteyn Lauren , Nini Andrea 
Published: March 2020

AbstractThis study investigates the extent to which there is individuality in how structural variation is conditioned over time. Earlier research already classified the diachronically unstable gerund variation as involving a high fraction of mixed-usage speakers throughout the change, whereby the proportion of the conservative variant versus the progressive variant as observable in the linguistic output of individual language users superficially resembles the mean proportion as observable at the population level. However, this study sets out to show that there can still be heterogeneity within such a centralized population in terms of how each individual conditions the observed variation. A random forest and conditional inference tree analysis of over 14,000 gerunds uttered by nineteen seventeenth-century authors is presented to show that, while the most important language-internal factors conditioning the gerund variation are adopted by (and shared between) all authors, we can still attest inter-individual variation (i) at lower levels of variable importance, and (ii) in the breadth of the range of contexts individual authors employ to condition the attested variation.
Venture Support Organizations – Lighting a Path for Entrepreneurship in South Africa?
Authors: Swartz Ethné , Marks Jonathan T. , Scheepers Caren 
Published: March 2020

AbstractThe papers in this special issue explore the rapid growth of venture development organizations globally. A consistent theme that runs throughout the contributions is that, while ecosystem development is necessary everywhere to enhance the economic impact of entrepreneurship, in emerging economies, contextualization is critical. Countries have idiosyncratic histories and development trajectories. Myriad stakeholders participate and shape local ecosystems. To illustrate, this introduction provides an overview of some key venture development initiatives in South Africa, and we consider how venture development organizations, particularly those based at academic institutions, could contribute to the development of the country’s entrepreneurial ecosystem. We provide suggestions for policy initiatives and academic research.
Optimized Dynamic Operation of Fixed-Speed Wind Farms Using Classical and Advanced Controllers

Published: March 2020

Abstract
Electric power systems are allowing higher penetration levels of renewable energy resources, mainly due to their environmental benefits. The majority of electrical energy generated by renewable energy resources is contributed by wind farms. However, the stochastic nature of these resources does not allow the installed generation capacities to be entirely utilized. In this context, this paper attempts to improve the performance of fixed-speed wind turbines. Turbines of this type have been already installed in some classical wind farms and it is not feasible to replace them with variable-speed ones before their lifetime ends. A fixed-speed turbine is typically connected to the electric grid with a Static VAR Compensator (SVC) across its terminal. For a better dynamic voltage response, the controller gains of a Proportional-Integral (PI) voltage regulator within the SVC will be tuned using a variety of optimization techniques to minimize the integrated square of error for the wind farm terminal voltage. Similarly, the controller gains of the turbine’s pitch angle may be tuned to enhance its dynamic output power performance. Simulation results, in this paper, show that the pitch angle controller causes a significant minimization in the integrated square of error for the wind farm output power. Finally, an advanced Proportional-Integral-Acceleration (PIA) voltage regulator controller has been proposed for the SVC. When the PIA control gains are optimized, they result in a better performance than the classical PI controller.
Scaling up network centrality computations – A brief overview
Authors: van der Grinten Alexander , Angriman Eugenio , Meyerhenke Henning 
Published: March 2020

Abstract
Network science methodology is increasingly applied to a large variety of real-world phenomena, often leading to big network data sets. Thus, networks (or graphs) with millions or billions of edges are more and more common. To process and analyze these data, we need appropriate graph processing systems and fast algorithms. Yet, many analysis algorithms were pioneered on small networks when speed was not the highest concern. Developing an analysis toolkit for large-scale networks thus often requires faster variants, both from an algorithmic and an implementation perspective. In this paper we focus on computational aspects of vertex centrality measures. Such measures indicate the (relative) importance of a vertex based on the position of the vertex in the network. We describe several common (and some recent and thus less established) measures, optimization problems in their context as well as algorithms for an efficient solution of the raised problems. Our focus is on (not necessarily exact) performance-oriented algorithmic techniques that enable significantly faster processing than the previous state of the art – often allowing to process massive data sets quickly and without resorting to distributed graph processing systems.

Abstract

Background
The ovotoxicity of 4-vinylcyclohexene diepoxide (VCD) has been established in several experimental models. Hesperidin (HSD) is a bi-flavonoid found in citrus fruits and has been reported to be a potent antioxidant and anti-inflammatory agent. Here, we have evaluated the rescue role of hesperidin on VCD-induced toxicity in the brain, ovary, and uterus of rats.

Methods
Six groups of rats containing ten rats in each group were orally given corn oil (control), hesperidin (100 mg/kg), hesperidin (200 mg/kg), VCD (250 mg/kg), VCD [(250 mg/kg)+hesperidin (100 mg/kg)] and VCD [(250 mg/kg)+hesperidin (200 mg/kg)] once a day for 30 days, respectively. Thereafter, we determined the selected biomarkers of oxidative damage, inflammation, endocrine balance, and histology of the reproductive organs.

Results
The data showed that hesperidin rescued VCD-induced increase in oxidative stress (hydrogen peroxide and malondialdehyde) and inflammatory (nitric oxide) biomarkers. In addition, hesperidin restored the reduction in antioxidant enzymes (catalase, glutathione S-transferase, glutathione peroxidase) activities and glutathione level in the brain, ovary, and uterus of rats (p<0.05). Lastly, hesperidin preserved the histological structure of the ovary and uterus of rats exposed to VCD.

Conclusions
Overall, the rescue role of hesperidin on VCD-induced toxicity in the brain and reproductive organs of female rats may be due to its antioxidative and anti-inflammatory properties.
