Background The use of cardiac magnetic resonance imaging is increasing, but its role in the diagnostic work-up following ischemic stroke has received limited study. We aimed to explore the added yield of cardiac magnetic resonance imaging to identify cardio-aortic sources not detected by transesophageal echocardiography among patients with cryptogenic stroke. Methods A retrospective single-center cohort study was performed from 01 January 2009 to 01 March 2013. Consecutive patients who had both a stroke protocol cardiac magnetic resonance imaging and a transesophageal echocardiography preformed during a single hospitalization were included. All cardiac magnetic resonance imaging studies underwent independent, blinded review by two investigators. We applied the causative classification system for ischemic stroke to all patients, first blinded to cardiac magnetic resonance imaging results; we then reapplied the causative classification system using cardiac magnetic resonance imaging. Standard statistical tests to evaluate stroke subtype reclassification rates were used. Results Ninety-three patients were included in the final analysis; 68.8% were classified as cryptogenic stroke after initial diagnostic evaluation. Among patients with cryptogenic stroke, five (7.8%) were reclassified due to cardiac magnetic resonance imaging findings: one was reclassified as “cardio-aortic embolism evident” due to the presence of a patent foramen ovale and focal cardiac infarct and four were reclassified as “cardio-aortic embolism possible” due to mitral valve thickening (n = 1) or hypertensive cardiomyopathy (n = 3). Overall, findings on cardiac magnetic resonance imaging reduced the percentage of patients with cryptogenic stroke by slightly more than 1%. Conclusion Our stroke subtype reclassification rate after the addition of cardiac magnetic resonance imaging results to a diagnostic work-up which includes transesophageal echocardiography was very low. Prospective studies evaluating the role of cardiac magnetic resonance imaging and transesophageal echocardiography among patients with cryptogenic stroke should be considered.

Background Health-related quality of life measured with the EuroQol Group 5-Dimension Self-Report Questionnaire was one of the secondary outcomes in the Multicenter Randomized Clinical trial of Endovascular treatment for Acute ischemic stroke in the Netherlands (MR CLEAN). We reported no statistically significant difference in EuroQol Group 5-Dimension Self-Report Questionnaire score between the intervention and control groups, but deaths were not included. Aims Reanalyze the effect of intra-arterial treatment for large vessel occlusion in acute ischemic stroke patients on health-related quality of life in more detail. We now include patients who died during follow-up. Methods The EuroQol Group 5-Dimension Self-Report Questionnaire questionnaires were obtained 90 days after treatment. We used the Dutch tariff to derive a utility index from the EuroQol Group 5-Dimension Self-Report Questionnaire score. Treatment effect was estimated with the Mann–Whitney U test and linear regression. The effect of treatment on the distribution of EuroQol Group 5-Dimension Self-Report Questionnaire dimension scores was assessed with ordinal logistic regression. Results We obtained EuroQol Group 5-Dimension Self-Report Questionnaire scores from 457 (91.7%) of the 500 patients, including 108 who died before follow-up. Median EuroQol Group 5-Dimension Self-Report Questionnaire score in the intervention group was 0.57, and 0.39 in the control group (p = 0.03). Treatment effect estimated with linear regression was 0.07 (95%CI: −0.001 to 0.143). Treatment specifically affected EuroQol Group 5-Dimension Self-Report Questionnaire dimensions “mobility” (OR: 0.43, 95%CI: 0.29–0.66), “self-care” (OR: 0.60, 95%CI: 0.41–0.89), and “usual activities” (OR: 0.53, 95%CI: 0.36–0.79). Conclusion Treatment had a limited effect on quality of life, as measured with the EuroQol Group 5-Dimension Self-Report Questionnaire. Nevertheless, patients with acute ischemic stroke caused by an intracranial occlusion in the anterior circulation, who had intra-arterial treatment, experience better health-related quality of life than patients without intra-arterial treatment.

Published: April 2017

Background: The effects of head impact in sports are of growing interest for clinicians, scientists, and athletes. Soccer is the most popular sport worldwide, but the burden of head impact in collegiate soccer is still unknown. Purpose: To quantify head impact associated with practicing and playing collegiate soccer using wearable accelerometers. Study Design: Descriptive epidemiological study. Methods: Mastoid patch accelerometers were used to quantify head impact in soccer, examining differences in head impact as a function of sex and event type (practice vs game). Seven female and 14 male collegiate soccer players wore mastoid patch accelerometers that measured head impacts during team events. Data were summarized for each athletic exposure, and statistical analyses evaluated the mean number of impacts, mean peak linear acceleration, mean peak rotational acceleration, and cumulative linear and rotational acceleration, each grouped by sex and event type. Results: There were no differences in the frequency or severity of head impacts between men’s and women’s soccer practices. For men’s soccer, games resulted in 285% more head impacts than practices, but there were no event-type differences in mean impact severity. Men’s soccer games resulted in more head impacts than practices across nearly all measured impact severities, which also resulted in men’s soccer games producing a greater cumulative impact burden. Conclusion: Similar to other sports, men’s soccer games have a greater impact burden when compared with practices, and this effect is driven by the quantity rather than severity of head impacts. In contrast, there were no differences in the quantity or severity of head impacts in men’s and women’s soccer practices. These data could prompt discussions of practical concern to collegiate soccer, such as understanding sex differences in head impact and whether games disproportionately contribute to an athlete’s head impact burden.
Semaphorin-Plexin signaling influences early ventral telencephalic development and thalamocortical axon guidance
Authors: Mitsogiannis Manuela D. , Little Graham E. , Mitchell Kevin J. 
Published: April 2017

Abstract

Background
Sensory processing relies on projections from the thalamus to the neocortex being established during development. Information from different sensory modalities reaching the thalamus is segregated into specialized nuclei, whose neurons then send inputs to cognate cortical areas through topographically defined axonal connections.
Developing thalamocortical axons (TCAs) normally approach the cortex by extending through the subpallium; here, axonal navigation is aided by distributed guidance cues and discrete cell populations, such as the corridor neurons and the internal capsule (IC) guidepost cells. In mice lacking Semaphorin-6A, axons from the dorsal lateral geniculate nucleus (dLGN) bypass the IC and extend aberrantly in the ventral subpallium. The functions normally mediated by Semaphorin-6A in this system remain unknown, but might depend on interactions with Plexin-A2 and Plexin-A4, which have been implicated in other neurodevelopmental processes.

Methods
We performed immunohistochemical and neuroanatomical analyses of thalamocortical wiring and subpallial development in Sema6a and Plxna2; Plxna4 null mutant mice and analyzed the expression of these genes in relevant structures.

Results
In Plxna2; Plxna4 double mutants we discovered TCA pathfinding defects that mirrored those observed in Sema6a mutants, suggesting that Semaphorin-6A − Plexin-A2/Plexin-A4 signaling might mediate dLGN axon guidance at subpallial level.
In order to understand where and when Semaphorin-6A, Plexin-A2 and Plexin-A4 may be required for proper subpallial TCA guidance, we then characterized their spatiotemporal expression dynamics during early TCA development. We observed that the thalamic neurons whose axons are misrouted in these mutants normally express Semaphorin-6A but not Plexin-A2 or Plexin-A4. By contrast, all three proteins are expressed in corridor cells and other structures in the developing basal ganglia.
This finding could be consistent with an hypothetical action of Plexins as guidance signals through Sema6A as a receptor on dLGN axons, and/or with their indirect effect on TCA guidance due to functions in the morphogenesis of subpallial intermediate targets. In support of the latter possibility, we observed that in both Plxna2; Plxna4 and Sema6a mutants some IC guidepost cells abnormally localize in correspondence of the ventral path misrouted TCAs elongate into.

Conclusions
These findings implicate Semaphorin-6A − Plexin-A2/Plexin-A4 interactions in dLGN axon guidance and in the spatiotemporal organization of guidepost cell populations in the mammalian subpallium.
The social grounds of anticommunism in South Korea-crisis of the ruling class and anticommunist reaction
Authors: Kim Dong-Choon 
Published: April 2017

AbstractI focused on how the domestic social grounds of anticommunism were interlinked with the external atmosphere like U.S. occupation, divided state-building and the Korean War. I especially emphasized the role of the Japanese collaborators in the post-colonial politics. Anticommunism as a political ideology surrendered to anticommunism as a rationale for the survival of class interests when historical task of overcoming colonialism was dominated by the Cold War atmosphere and full scale war. When North Korea’s threats came to reality by the outbreak of the Korean War, hysteric style of anticommunism came to dominate the other forms of anticommunism. The chronic occurrence of anticommunist hysteria may be explained by the political landscape. It was not just the result of U.S. occupation force’s policy, the international Cold War, but of the failure of de-colonization, by which former Japanese collaborators became the hegemonic groups among Korea’s anticommunists, left dark shadow on South Korea’s politics.
The changing landscape of school choice in Canada: From pluralism to parental preference?
Authors: Bosetti Lynn , Van Pelt Deani , Allison Derek 
Published: April 2017

This paper provides a descriptive account of the growing landscape of school choice in Canada through a comparative analysis of funding and student enrolment in the public, independent and home-based education sectors in each province. Given that the provinces have responsibility for K-12 education, the mixture of public, independent and home school education varies rather widely by province, as does the level of funding and regulation. Delivery and funding of public education in Canada has long prioritized limited linguistic and religious pluralism, providing various options for English or French, and Catholic or Protestant alternatives to qualified parents. More recently growing numbers of parents have been seeking more options for their children’s education. This has fueled slow but steady growth in independent schools and home schooling.

Doktoranci – grupa wybrana czy przegrana? Prezentacja wniosków studium teoretyczno-empirycznego na temat studiów doktoranckich w Polsce
Authors: Kola Anna Maria 
Published: April 2017

Artykuł prezentuje wnioski z badań dotyczących studiów doktoranckich w Polsce, będących częścią szerzej zakrojonego projektu badawczego na temat kreowania elit społecznych. Celem poznawczym przytaczanych badań był próba opisania i wyjaśnienia faktu społecznego, jakim jest kształcenie elitarne na poziomie wyższym. Z tego powodu należy naszkicować obraz ważneg i dotąd nieopisanego zjawiska na gruncie polskiej edukacji, czyli studiów doktoranckich w ich nowym kształcie. Nieobowiązująca już ustawa o szkolnictwie wyższym z dnia 27 lipca 2005 r. w Dziale IV, w Rozdziale 4 precyzyjnie przedstawiała sposób funkcjonowania studiów doktoranckich, ze szczególnym uwzględnieniem praw i obowiązków doktoranta. Dzięki tym regulacjom przypominały one formalnie studia pierwszego i drugiego stopnia. Różnicowało je zaś coś, co można byłoby nazwać ich „misją”. Doktorant bowiem był potencjalnym kandydatem na pracownika naukowego, mającego być w przyszłości członkiem elity intelektualnej. Posiadał on predyspozycje (intelektualne, interpersonalne, społeczne, emocjonalne, a nawet fizyczne) umożliwiające pracę naukową, będące częścią jego kapitałów – społecznego, kulturowego czy finansowego. Od nich, według badaczy problemu stratyfikacji społecznej, zależał sukces życiowy i uniwersytecki, silnie związany z determinacją, motywacjami, ale też wsparciem osób trzecich (głównie promotora). Od 2011 r., a zatem wraz ze zmianą ustawodawstwa, forma kształcenia na poziomie studiów doktoranckich uległa zmianie. By jak najlepiej scharakteryzować fenomen studiów trzeciego stopnia, biorąc pod uwagę ich wartość i zadania, ale też praktykę uniwersytecką, i – być może – wskazać sposoby udoskonalenia tego modelu studiów, należy zasięgnąć opinii tych, którym analizowana forma kształcenia jest oferowana. Z tego powodu przedmiotem badań zostały identyfikacje i orientacje życiowe grupy 31 doktorantów z różnych polskich uniwersytetów, przedstawiane w wywiadach narracyjnych. Całość wniosków z badań zawiera oddana do druku monografia pt. Kształcenie elit społecznych? Studia doktoranckie w Polsce jako forma i potrzeba konstruowania zapoznanego mitu.

Abstract
Nassib, SH, Mkaouer, B, Riahi, SH, Wali, SM, and Nassib, S. Prediction of gymnastics physical profile through an international program evaluation in women artistic gymnastics. J Strength Cond Res 34(2): 577–586, 2020—The purpose of this study was to investigate the most appropriate aptitudes for top-level sporting results to identify physical profile of talent identified women's artistic gymnastics (WAG). Forty-eight women's artistic gymnasts in the provincial team (age 11.12 ± 1.22 years; height 1.35 ± 0.04 m; body mass 28.5 ± 4.04 kg) voluntarily participated in this study. Anthropometrics measures and the WAG battery physical tests were used to ensure a systematic approach for the WAG development worldwide. The present findings revealed that the strength (static strength, speed strength, and endurance strength), power and flexibility seem to be important and essential for good performance. Another characteristic that emerged from the results of the physical domain is coordination. This motor skill may seem relevant to gymnastics, they are applicable to the gymnasts' ability to perform all apparatus and more generally they relate to the ability to accurately perform whole-body skills supported by the leg on the floor, balance beam, and vault. Therefore, athletic performance can be boosted using combination of several characteristics that seems to be important for an elite gymnast. This reinforcing the view that systematic approach for the development and mufti-dimensional profile seems promising.

Professional Development, Motivation, and Community in a Moscow In-service Recertification Course
Authors: Hull Tony 
Published: April 2017

Between September 2010 and May 2013, the author conducted six cycles of an 8-week recertification course for in-service English teachers in Moscow, Russia. The course syllabus was built on developing a community of practice, as a motivating factor in teacher development. The community was fostered both during in-person meeting time and online participant interaction. While the participants’ objectives were varied, the overarching goal of the course – beyond knowledge and skill building – was to engender a sense of ownership among the participants, both of the course itself and of their own continuing professional development. This was realized in both small incremental ways, such as launching a new discussion online, and in bolder, farther-reaching ways, such as organizing a mini-conference for a local school district.
Self-Regulation Skills: Several Ways of Helping Students Develop Self-Regulated Learning
Authors: Baranovskaya Tatiana 
Published: April 2017

Empirical research supports the long held assumption that self-control, self-esteem, and motivational orientations of adult language learners are important factors in their language learning behavior. However, precisely these variables influence the language learning process has yet to be investigated. The goal of this paper is to examine the role of how self-control, self-esteem and motivational orientations influence the English language learning process. Recent methodological advances and various theoretical frameworks that have guided the present research are considered in this paper. A special “bidirectional course” turning on teacher-learner interaction was designed - a communicative course which promoted learner autonomy. The results indicate that active involvement in learning, monitoring motivation, self-control and self–esteem are positively related to learning outcomes, demonstrating that the acquisition of self-regulation skills have a positive impact on the learning of English.
Imagens do futebol na literatura alemã contemporânea
Authors: Cornelsen Elcio Loureiro 
Published: April 2017

Nossa contribuição visa a uma análise das imagens do futebol na Literatura Alemã Contemporânea. Nesse intuito, elegemos as seguintes obras para comporem o corpus de análise: o conto Der Sonntag, an dem ich Weltmeister wurde (1994; O domingo em que me tornei campeão do mundo), de Friedrich Christian Delius, e o monólogo teatral Leben bis Männer (2001; Vivendo até se tornarem homens), de Thomas Brussig. Enquanto o conto de Delius retrata, ficcionalmente, a partir do olhar memorialista, a primeira conquista da seleção alemã em 1954, na Copa da Suíça, o longo monólogo teatral de Thomas Brussig apresenta uma única personagem, um treinador de futebol em fim de carreira, que treinava equipes infantis e infanto-juvenis no passado, ainda na Alemanha Oriental.
Herramienta multimedial para el estudio de la anatomía del oído a través de modelos virtuales
Authors: Pérez Gutiérrez Byron Alfonso , Uribe Quevedo Alvaro Joffre 
Published: April 2017

Este trabajo presenta la metodología planteada y aplicada para desarrollar una herramienta de tipo multimedia, basada en estándares de internet e imágenes tridimensionales con el objetivo de complementar el proceso de aprendizaje relacionado al estudio de la anatomía del oído humano a través del uso de objetos 3D que incrementen el grado de inmersión e interacción respecto a los modelos reales. Las ayudas visuales tradicionales están basadas en fotografías, ilustraciones, bosquejos y observación directa de los tejidos a través de microscopio, y todas ellas, aun cuando complementarias, presentan algunas limitantes debido a la naturaleza microscópica de algunas partes del oído. Para solucionar las deficiencias presentadas en las técnicas actuales, se propone el desarrollo de una herramienta computacional complementaria que incluya modelos 3D animados e información sobre cada órgano siguiendo los requerimientos de especialistas en el área. Los modelos 3D fueron desarrollados a partir tomografías computarizadas, fotografías y modelos reales, con el fin de obtener un gran realismo y similitud con su contraparte real. La edición de los modelos anatómicos tuvo en cuenta aspectos técnicos de los equipos de cómputo estándar con el fin de garantizar que los usuarios tengan no solo acceso a la herramienta, sino que puedan utilizarla sin una reducción poligonal que afecte el realismo de los modelos y la navegación fluida en el ambiente virtual. La validación de este trabajo fue realizada por especialistas en el área, con el objetivo de garantizar que se cumpla con los requerimientos de información y navegación, para poder ser probada en grupos de estudiantes como herramienta complementaria de estudio.

Este artículo revisa la comprobada fundamentación pedagógica de LOGO (Papert,2003) que a su vez ofrece interesantes estrategias de motivación para los niños, en aspectos tales como el desarrollo de habilidades espaciales a través de su propia exploración de mundos virtuales. La metodología original fue propuesta por Seymour Papert para escenarios en dos dimensiones (2D). Por lo tanto, se analiza la posibilidad de integrar las ventajas pedagógicas de LOGO con una interfaz gráfica en tres dimensiones (3D), al aprovechar la tecnología contemplada en los estándares del consorcio Web3D. Además menciona los componentes X3D que permiten el uso de avatares (humanoides) para facilitar la interacción de los usuarios en mundos virtuales dinámicos, al disponer de personajes adicionales al de la tortuga de LOGO.
