On locally compact shift-continuous topologies on the α-bicyclic monoid
Authors: Bardyla Serhii 
Published: April 2018

AbstractA topology τ on a monoid S is called shift-continuous if for every a, b ∈ S the two-sided shift S → S, x ↦ axb, is continuous. For every ordinal α ≤ ω, we describe all shift-continuous locally compact Hausdorff topologies on the α-bicyclic monoid Bα. More precisely, we prove that the lattice of shift-continuous locally compact Hausdorff topologies on Bαis anti-isomorphic to the segment of [1, α] of ordinals, endowed with the natural well-order. Also we prove that for each ordinal α the α + 1-bicyclic monoid Bα+1is isomorphic to the Bruck extension of the α-bicyclic monoid Bα.
Chemical Routes to Surface Enhanced Infrared Absorption (SEIRA) Substrates
Authors: Stanglmair Christoph , Neubrech Frank , Pacholski Claudia 
Published: April 2018

Abstract
Bottom-up strategies for fabricating SEIRA substrates are presented. For this purpose, wet-chemically prepared gold nanoparticles are coated with a polystyrene shell and subsequently self-assembled into different nanostructures such as quasi-hexagonally ordered gold nanoparticle monolayers, double layers, and honeycomb structures. Furthermore elongated gold nanostructures are obtained by sintering of gold nanoparticle double layers. The optical properties of these different gold nanostructures are directly connected to their morphology and geometrical arrangement – leading to surface plasmon resonances from the visible to the infrared wavelength range. Finally, SEIRA enhancement factors are determined. Gold nanoparticle double layers show the best performance as SEIRA substrates.

Published: April 2018

Objective
The primary objective of this study was to compare the levels of oxidative stress biomarkers between pregnancies with gestational diabetes mellitus (GDM) and normoglycemic pregnancies.

Materials and methods
A prospective study was conducted on pregnant women at average risk for GDM. The participants were screened for GDM with glucose challenge test and confirmed by 100 g, 3-h oral glucose tolerance test and categorized into the control (non-GDM) and GDM groups. Maternal blood was collected from all participants at gestational age (GA) 24–28 weeks and early labor and fetal cord blood was collected for measurements of 8 Isoprostane (8Isop) (oxidative stress marker), TNF-α (inflammatory marker) and IL-10 (anti-inflammatory marker) and were followed up for maternal and neonatal outcomes.

Result
A total of 62 women, 30 in GDM and 32 in control group, met the inclusion criteria. At 24–28 weeks of gestation, maternal serum 8Isop and TNF-α levels were significantly higher in GDM group (P = 0.032 and P = 0.047), in spite of good glycemic control. At early labor, maternal 8Isop levels were significantly higher in GDM (P = 0.001). The biomarkers in the cord blood as well as maternal and neonatal outcomes in both groups were not significantly different.

Conclusion
GDM is significantly associated with inflammatory process when compared to normal pregnancy, as indicated by higher oxidative stress and apoptosis markers. However, such levels were not correlated with the pregnancy outcomes. An increase in oxidative stress could not be prevented by good glycemic control. Cord blood biomarker levels in pregnancy with GDM were not changed, suggesting that the placenta could be the barrier for the oxidative stress and cytokines.

Authors: Yang Yang , Shi Xi Xi Xi , Huang Xing Fang Fang 
Published: April 2018

Let {Xi , i ⩾ 1} be a sequence of identically distributed real-valued random variables with common distribution FX; let {θi , i ⩾ 1} be a sequence of identically distributed, nonnegative and nondegenerate at zero random variables; and let τ be a positive integer-valued counting random variable. Assume that {Xi , i ⩾ 1}, {θi , i ⩾ 1} and τ are mutually independent. In the presence of heavy-tailed Xi's, this paper investigates the asymptotic tail behavior for the maximum of randomly weighted sums Mτ = max1 ⩽ k ⩽ τ ∑ki = 1θi Xi under the condition that {θi , i ⩾ 1} satisfy a general dependence structure.

Published: April 2018

Abstract
This Document, “Guidelines for personal exposure monitoring of chemicals” (“this Guideline”), has been prepared by “The Committee for Personal Exposure Monitoring” (“the Committee”) of the Expert Division of Occupational Hygiene & Ergonomics, Japan Society for Occupational Health. Considering the background of the growing importance of personal exposure monitoring in risk assessment and the need to prepare for the introduction of monitoring using personal samplers from an administrative perspective in recent years, the Committee was organized in November 2012. The Committee has prepared this Guideline as a “practical guideline” for personal exposure monitoring, so as to offer proposals and recommendations to the members of the Japan Society for Occupational Health and to society in general. The scope of this Guideline covers all chemical substances and all related workplaces regarded as targets for general assessment and the management of risk. It thus is not to be considered to comment on legal regulations and methodology. The main text provides the basic methods and concepts of personal exposure monitoring, while 31 “Appendices ” are provided in this Guideline throughout the series; technical descriptions, statistical bases, and actual workplace examples are provided in these appendices, to assist better understanding. The personal exposure monitoring described as per this Guideline is equivalent to an “ expert-centered basic method to reasonably proceed with the assessment and management of risk at workplaces.” It is considered that practicing and expanding on this method will significantly contribute in reforming the overall framework of occupational hygiene management in Japan.

Published: April 2018

While social competence is widely studied, relatively few studies are aimed at investigating social competence at elementary school years. Furthermore, social competence tends to be dependent on social and cultural context; hence instrument developed in one country may require significant adaptations in other countries. Thus, the purpose of the present study was to develop a Lithuanian questionnaire for assessment of social competence at elementary school.
Individual items for the Elementary School Social Competence Questionnaire were drawn from the Early Developement Instrument (Janus et al., 2007), the Social Emotional School Readiness Scale (Bustin, 2007), and the Social Competence Inventory (Rydell et al., 1997). The study was conducted in two waves. In the first wave subjects were 437 first graders (198 boys and 239 girls) from Lithuania. In the second wave, which took place a year after, 192 boys and 228 girls participated.
The Elementary School Social Competence Questionnaire was developed from the initial pool of items using structural equation modeling. The Questionnaire contained the Communicative Social Competence Subscale and the Ability to Take Directions Subscale. The initial measurement model was confirmed using confirmatory factor analysis on the dataset obtained during the second wave of measurement. Both subscales demonstrated good internal and test-retest reliability. Construct validity of the instrument was assessed by correlating its subscales with student-teacher relationship, in-class popularity, and school anxiety measures.
Evaluation of School Heads’ General Competencies within Prescriptive and Descriptive Insight
Authors: Cibulskaitė Nijolė , Petrauskas Evaldas 
Published: April 2018

The modern management of general education schools sets high requirements for school heads’ managerial competencies. This research aim is to determine how school heads evaluate the importance of managerial competencies and their mastery level, as well as to highlight the relevant areas for improvement. Solving the study objectives, the article discusses theoretical provisions of school heads’ managerial competencies evaluation, and gives the overview of some institutional evaluation results. The empirical research data reveals prescriptive and descriptive insights to the importance of managerial school heads’ competencies and their components in a school leader work.
Performed meta-analysis of the results helped to confirm that selected research strategies and methods are suitable to examine school heads’ general competencies evaluation problem. Research data led to assume that during institutional evaluation more attention is paid to the competencies which are important in the prescriptive terms, meanwhile school heads emphasize competencies in the descriptive terms, as they are more useful in their practical work.
Trends in the Modelled Direction of Education and Context Tensions
Authors: Bruzgelevičienė Ramutė 
Published: April 2018

The article analyses the problem of Lithuanian modelled education direction and context tensions in the current stage of the development of Lithuanian education, raising a problematic research question: why do tensions form between the envisaged education direction and the assessment of its current development? The methodological approach is based on qualitative documentary research. The theoretical basis of the research is the conception of threefold education reforms: equal opportunities, financial considerations, competition-driven, the conception of two approaches to education: humanistic-cultural and pragmatic-technological. Conclusions are presented based on the data analysis carried out by applying the deductive version of a qualitative content analysis method.
From the very start of the reform, the analysed government-level education documents reveal a comparatively consistent adherence to a reconstructionist mission of education, value principles such as humanity, democratic character, national dimension, renewal, however, the philosophical basis of education and upbringing that would provide the system a paradigmatic direction has not been named directly.
Some of the education experts participating in the investigated discourse on education describe the state of education using such concepts as eclecticism, marsh, abyss, etc. This assessment is constantly reproduced by the mass media and may result in the stagnation of education practice and the formation of the negative attitude of society toward education.
The experts who assess the state and problems of education moderately affirm the establishment of market relations in education, prevalence of economic-financial expedience in decision making, i.e. they acknowledge that alongside with the reform of equal opportunities, modelled during the start-up period of the education reform, reforms driven by financial considerations and competition begin to prevail. For this reason, post strategic educational decisions which represent the directions of threefold reforms and contradict each other on a philosophical and value basis make assumptions for the formation of tensions in assessing the current direction of the development of education.
Teacher’s Provided Feedback and Students’ Dropout Intentions: the Role of Basic Psychological Needs
Authors: Raižienė Saulė , Gabrialavičiūtė Ingrida , Garckija Renata , Kalesinskas Laurynas 
Published: April 2018

Teacher’s feedback is one of the most important factors in educational domain and is crucial in students’ academic motivation, performance and well-being at school. Students’ dropout from school is a common problem in many educational settings. Students who form dropout intentions can in the future act on these intentions. Self-determination theory is useful in explaining the ways how teacher’s feedback can influence the dropout intentions through satisfaction and thwarting of basic psychological needs for autonomy, competence, and relatedness.
The goal of this study is to analyze the mediating role of basic psychological needs satisfaction and frustration in the relationships between positive and negative teacher’s feedback and student’s dropout intentions. The participants were 682 (aged 14–18; 49.1% females) students of I–III gymnasium grades from 7 schools.
The results showed that only negative teacher’s feedback and the frustration of need for relatedness predicted dropout intentions. When teachers provide negative feedback, the students’ need for relatedness is frustrated and they are more likely to form dropout intentions. Even though the positive teacher’s feedback increases the satisfaction of students’ needs for autonomy, competence and relatedness, it does not predict dropout intentions. Finally, the results provided support for the assumed meditational role of one of the basic psychological need thwarting in teachers’ behavior as social factor to negative educational outcomes.

Published: April 2018

Physical activity is a fundamental means of improving physical and mental health. Although academic youth can be described as a relatively healthy population group of society, both in Lithuania and other countries research data suggests that many students do not meet the physical activity recommendations of the World Health Organization. Knowing how important an adequate physical activity is in the life of students it is necessary to identify maintaining factors and barriers which condition this activity.
The object of research is physical activity and factors influencing it.
The aim is to establish physical activity and its determinants among students of Lithuanian University of Educational Sciences.
The survey was conducted in 2013–2014. The study population consisted of first-year full-time students from the Lithuanian University of Educational Sciences from 20 teachers’ training study programs. The sample size was 432 persons (32.6% males and 67.4% females) aged 18–23 (mean age 19.35 ± 1.02). An anonymous paper-and-pencil questionnaire was used to collect data on university students’ socio-demographic characteristics, self-reported health status, and maintaining factors or perceived barriers to physical activity participation. The physical activity levels were measured using the International Physical Activity Questionnaire – IPAQ. Statistical analysis of the data was performed using SPSS software package, version 16.0. To assess contingency tables, Chi-square test was used. Differences were considered to be statistically significant at p < 0.05.
According to the results of the presented study 16.2% of the students had low, 29.9% – moderate, and 53.9% – high level of physical activity. Significantly higher physical activity was observed among males (69.5%) than females (46.4%). The results showed that most commonly reported factors positively impacting on participation in physical activity are perceived health benefits (70.5%) and the aspiration to maintain good physical shape (58,3%). The results of the research also confirmed that barriers to physical activity are a lack of time (44.7%), lack of will, stubbornness, and laziness (29.6%).

Abstract

Lessons Learned
Due to evolving imaging criteria in brain tumors and variation in magnetic resonance imaging evaluation, it is not ideal to use response rate as a primary objective. Future studies involving antiangiogenic agents should use overall survival. Disease-expected toxicities should be considered when defining the clinical significance of an adverse event. For example, vascular thromboembolic events are common in brain tumor patients and should not be attributed to the study drug in the safety analysis.

Background
Recurrent malignant glioma (rMG) prognosis is poor, with a median patient survival of 3–11 months with bevacizumab (BEV)-containing regimens. BEV in rMG has 6-month progression free survival (PFS-6) of ∼40% and an objective response rate of 21.2%. BEV-containing regimens improve PFS-6 to 42.6%–50.3%, indicating that BEV combination therapies may be superior to single agent. Rilotumumab, a hepatocyte growth factor (HGF) antibody, inhibits angiogenesis and expression of angiogenic autocrine factors (e.g., vascular endothelial growth factor [VEGF]) by c-Met inhibition. Combination of rilotumumab with BEV to block vascular invasion and tumor proliferation may synergistically inhibit tumor growth.

Methods
Thirty-six BEV-naïve rMG subjects received rilotumumab (20 mg/kg and BEV (10 mg/kg) every 2 weeks. Endpoints included objective response rate (using Response Assessment in Neuro-Oncology [RANO] criteria), PFS-6, overall survival (OS), and toxicity.

Results
Median patient follow-up was 65.0 months. Objective response rate was 27.8% (95% confidence interval [CI]: 15.7%–44.1%). Median OS was 11.2 months (95% CI: 7–17.5). PFS-6 was 41.7% (95% CI: 25.6%–57.0%). Most frequent treatment-related grade ≤2 events included weight gain, fatigue, allergic rhinitis, and voice alteration; grade ≥3 events included venous thromboembolism (four patients), including one death from pulmonary embolism.

Conclusion
Rilotumumab with BEV did not significantly improve objective response compared with BEV alone, and toxicity may preclude the use of rilotumumab in combination BEV regimens.
Using Rhetorical Flexibility to Bridge Advanced Reading/Writing/Grammar with English 101
Authors: Selvidge Jenny 
Published: April 2018

By successfully completing Level 5 of the five-level intensive English program at the Applied English Center (AEC), students can fulfill the university’s ESL requirement and exit the IEP. As a new coordinator to AECR 151, Level 5 Reading/Writing/Grammar, I felt unsure of where students were going after they left the IEP. I knew very little about the English Department and even less about English 101. What were students being asked to do? Were they struggling? Were they thriving? Did we prepare them well? To get a better sense of this, I met with Sonya Lancaster, Associate Director of Freshmen-Sophomore English. Through our discussion, I quickly realized that our students were only being equipped with a specific range of English skills: skills that prepared them to write structurally and grammatically sound essays based on prompts that were given to them. What English 101 requires students to do is to use language to think outside of the box and to use rhetorical flexibility. I was new to this term, but I have now embraced this as one of the central pieces of our L5 writing curriculum.
