Do Executive Functions Mediate the Link between Socioeconomic Status and Numeracy Skills? A Cross-Site Comparison of Hong Kong and the United Kingdom
Authors: Ellefson Michelle Renee , Zachariou Antonia , Ng Florrie , Wang Qian , Hughes Claire
Published: December 2019

In the fields of education, sociology and economics, there is a long-standing connection between socioeconomic status (SES) and school outcomes in a wide variety of cultural settings, but these studies have yet to examine the possible mediating effects of domain-general cognitive factors such as executive functions (EF). Addressing this gap and building on evidence for links between EF and numeracy, the current cross-cultural study used a large sample (N = 835) of 9- to 16-year-old children from Hong Kong and the United Kingdom to the examine the independence and interplay of SES and EF as predictors of numeracy skills. Our analyses yielded three key findings: (1) EF consistently predicts numeracy skills across sites and genders; (2) Associations between SES and EF differ by site and gender; and (3) Associations between numeracy skills and SES/EF differ by site and gender. Together with previous findings, our results suggest culture-specific associations between SES, EF and numeracy, indicating that cultural insights may enable impactful shifts in public policy to narrow the achievement gap between children from affluent and disadvantaged families.
Learning functions actively
Authors: Schulz Eric
Published: December 2019

How do people actively learn functional rules, i.e. a mapping of continuous inputs onto a continuous output? We investigate information search behavior in a multiple-featurefunction learning task in which participants either actively select or passively receive observations. We find that participants benefit from actively selecting information, inparticular in their function extrapolation performance. By introducing and comparing different models of active function learning, we find that participants are best described by a non-parametric function learning model that learns about both the underlying function and inputs that are likely to produce high outputs. These results enrich our understandingof active function learning in complex domains.

Published: December 2019

A child’s socio-economic environment can profoundly affect their development. While existing literature focusses on simplified metrics and pair-wise relations between few variables, we aimed to capture complex interrelationships between several relevant domains using a broad assessment of 519 children aged 7–9 years. Our analyses comprised three multivariate techniques that complimented each other, and worked at different levels of granularity. First, an exploratory factor analysis (principal component analysis followed by varimax rotation) revealed that our sample varied along continuous dimensions of cognition, attitude and mental health (from parallel analysis); with potentially emerging dimensions speed and socio-economic status (passed Kaiser’s criterion). Second, k-means cluster analysis showed that children did not group into discrete phenotypes. Third, a network analysis on the basis of bootstrapped partial correlations (confirmed by both cross-validated LASSO and multiple comparisons correction of binarised connection probabilities) uncovered how our developmental measures interconnected: educational outcomes (reading and maths fluency) were directly related to cognition (short-term memory, number sense, processing speed, inhibition). By contrast, mental health (anxiety and depression symptoms) and attitudes (conscientiousness, grit, growth mindset) showed indirect relationships with educational outcomes via cognition. Finally, socio-economic factors (neighbourhood deprivation, family affluence) related directly to educational outcomes, cognition, mental health, and even grit. In sum, cognition is a central cog through which mental health and attitude relate to educational outcomes. However, through direct relations with all components of developmental outcomes, socio-economic status acts as a great ‘unequaliser’.
Dale and the Bomb: Exploring the Nuclear Future and Cold War Anxiety in 1950s Canadian Children’s Literature
Authors: Reilly Frances V.
Published: December 2019

Between 1950 and 1962, Joe Holliday wrote an adventure series called Dale of the Mounted, which consisted of 12 novels featuring Dale Thompson, a young constable of the Royal Canadian Mounted Police. Written for children and adolescents at a time when few books were directed toward young Canadians, these books stood out. What is more remarkable about this series is the author’s use of contemporary Cold War headlines in Dale’s adventures, such as nuclear meltdowns and atomic research, espionage plots, refugee crises, and the construction of northern radar systems. Holliday presented Cold War dramas to children as a means of educating them about their country and current events in an entertaining manner. This article focuses on two of Holliday’s Cold War adventures in particular, Dale of the Mounted: DEW Line Duty (1957) and Dale of the Mounted: Atomic Plot (1959). Both books express excitement for the future of Canadian science, technology, and industry, while the storylines are weighted in Cold War anxieties about espionage and nuclear disaster. This article explores the balance between fear and hope in the nuclear era. Holliday’s books stress the importance of control and order in a period of uncertainty and potential chaos. As rare examples of Canadian atomic culture in a decade dominated by American film and literature, DEW Line Duty and Atomic Plot are unique displays of Canadian Cold War society during the 1950s.
Narratives and the New Farmer in Cape Breton:“It’s Who We Are”
Authors: Beaton Elizabeth
Published: December 2019

Can small, diversified farms thrive, or even survive, in Canada’s current agricultural milieu? Can they stand against the highly industrialized operations encouraged by Canadian policy, international trade, and capital interests? This study suggests that there is reason for optimism. Well-known visionaries, Canadian and worldwide, note a “new trajectory” in the context of the looming failure of current systems in agriculture, based on concerns for the environment and on the relationship between producers and consumers. Approaches to small, diversified farming operations come under several headings: economical, post-productive, civic. But it is the concrete experiences of individuals, families, and communities that truly give weight to the potential for sustainable food production. This research on Cape Breton Island farming—where self-sufficiency in food production is a strong tradition—presents a range of farming “styles” (as defined by Jan Douwe van der Ploeg) that are related to land acquisition, innovative marketing, support services, decisions about farm size and products, and the benefits of non-farm work as a farm subsidy. Interview narratives give voice to the actions of Cape Breton Island farmers who work within an “isolation paradox” as a way forward for their small farms.

In this article I discuss the tradition of African American parental involvement in the pre-Brown era, challenges to parental involvement in a post-Brown era, and a parental involvement initiative in an urban elementary school. I conclude with a discussion of the continued imperative for African American parental involvement and some implications for leadership.
Thinking Outside the (Bricks-and-Mortar) Box(es): Using Cyberspace Technology to Reconceptualize Schooling and Community in the Face of Resegregation
Authors: Becker Jonathan D.
Published: December 2019

As the 50th anniversary of the landmark Brown v. Board of Education decision arrives, a notably gesellschaftliche (individualist, freedom- oriented, rationalist) paradigm in the education policy agenda prevails. That is to say, in the wake of a series of Supreme Court decisions and the proliferation of publicly funded, ethnocentric charter schools in the past few decades, this country has moved away from Brown’s celebrated ideals and closer to the old idea of “separate but equal.” Furthermore, the disconnect is occurring along racial and cultural lines. Thus, if we are to achieve the benefits of diversity in schooling and create a more gemeinschaftliche (communitarian, help-oriented, democratic) orientation in education, we must think outside of the box; we must think digitally. The Internet as an embodiment of multiple forms of computer-mediated communications is a notably communal space imbued with gemeinschaftliche properties. Thus, to the traditional forms of schooling, we should look to add the community-building nature of computer-mediated communications to create virtual learning communities that bring together young people of different racial, cultural, economic and/or geographic identifications.

This article provides a community relations professional the rationale and background regarding the use of Universal Instructional Design in classrooms. It also provides community relations specialists with a communication plan for educating the public on Universal Instructional Design via a teaching and modeling approach. Results of a recent study of Missouri public school teachers indicate that Universal Instructional Design is a fairly new concept to K–12 educators and should thus be explored as well as communicated to parents and community so that it can become an accepted method of instruction to aid in student success.
Community-Building and One-Way Tweets: How American “Effective Schools” Use Twitter for Stakeholder Communication
Authors: Maben Sarah , Hodges Brianna Henneke , Goen Karley
Published: December 2019

Researchers analyzed 1,948 tweets from 13 independent school districts in the U.S.-based Effective Schools Project for evidence of one-way and two-way communication with stakeholders over a 45-day period. In this mixed method study, tweets were overwhelmingly one-way in nature, consistent with existing literature; only 1.9% of tweets were categorized as two-way communication, or seeking response and soliciting feedback from stakeholders. The majority of tweets served a community- building purpose. Themes of the highlight reel, reliance on links to other sites or social networks, text-heavy messages, and centralized versus decentralized posting emerged from the school district tweets.

Specifically, the goal of this article is to examine the school superintendent as the chief public relations practitioner of the school system and how he/she would operate as such in the realms of seven public relations theories, as the superintendent works toward meeting the goals and objectives of his/her school district: strategic management function, communitas versus corporatas, persuasion, storytelling and branding, postmodernism, understanding, and sociology.
How to Reduce Motorcycle Theft in Parking at a Manaus Shopping?
Authors: Gomes da Silva Jonas , Sousa de Oliveira Caroline , Barbosa de Alencar David
Published: December 2019

According to a survey conducted by the Brazilian Association of Shopping Centers in 2016, every nine days, a mall is robbed in Brazil. Faced with this scenario, shopping malls are increasingly concerned with customer safety, as they sell to consumers the idea of safety, convenience and comfort. In mall X, located in one of the busiest Manaus (Amazon capital in Brazil) city avenues, it was found that expenses with robberies and theft reimbursement in parking areas increased considerably in 2015. Thus, this article aims to propose low cost actions to reduce robberies and theft in the parking areas of this mall with the highest incidence of claims. Data were collected through spreadsheets and reports from the Customer Service System (CSS) and the outsourced contractor to operate the parking service. After data collection and analysis, it was concluded that motorcycle parking is the part of parking most affected by the problem, and possible solutions such as control by labels and helmet locks are suggested, and it is up to the mall managers to choose which of the improvement proposals are more feasible.

Authors: Zheng Jia-Ping , Li Chu-Zhong , Chen Guo-Qiang
Published: December 2019

OBJECTIVE

The aim of the present study was to investigate the practical value of a multimaterial and multicolor 3D-printed model in anatomical teaching, surgical training, and preoperative planning of transnasal endoscopic surgery for pituitary adenoma.

METHODS

Multimodality neuroimaging data were obtained in a 42-year-old healthy male volunteer and a 40-year-old female patient with an invasive nonfunctional pituitary adenoma. Three 3D-printed models were produced: a monomaterial and monocolor model, a monomaterial and multicolor model, and a multimaterial and multicolor model. The effects on anatomical teaching and surgical training for exposing the vidian nerve were assessed by 12 residents, and the training effect was validated on cadavers. The practical values for preoperative planning were evaluated by 6 experienced neurosurgeons. All evaluations were based on 5-point Likert questionnaires.

RESULTS

The multimaterial and multicolor model was superior to the monomaterial models in surgical training for exposing the vidian nerve (Fisher test; p < 0.05). In addition, the multimaterial and multicolor model was superior to the monomaterial models in anatomical teaching and preoperative planning (Friedman test; p < 0.05).

CONCLUSIONS

Multimaterial and multicolor 3D printing technology makes it convenient and efficient to produce a practical model for simulating individualized and complex anatomical structures in the sellar region. Furthermore, the multimaterial model can provide a more realistic manipulative experience for surgical training and facilitate the preoperative planning.
Magnetic resonance vessel wall imaging in cerebrovascular diseases
Authors: Young Christopher C. , Bonow Robert H. , Barros Guilherme , Mossa-Basha Mahmud , Kim Louis J. , Levitt Michael R.
Published: December 2019

Cerebrovascular diseases manifest as abnormalities of and disruption to the intracranial vasculature and its capacity to carry blood to the brain. However, the pathogenesis of many cerebrovascular diseases begins in the vessel wall. Traditional luminal and perfusion imaging techniques do not provide adequate information regarding the differentiation, onset, or progression of disease. Intracranial high-resolution MR vessel wall imaging (VWI) has emerged as an invaluable technique for understanding and evaluating cerebrovascular diseases. The location and pattern of contrast enhancement in intracranial VWI provides new insight into the inflammatory etiology of cerebrovascular diseases and has potential to permit earlier diagnosis and treatment. In this report, technical considerations of VWI are discussed and current applications of VWI in vascular malformations, blunt cerebrovascular injury/dissection, and steno-occlusive cerebrovascular vasculopathies are reviewed.

Published: December 2019

Numerous recent technological advances offer the potential to substantially enhance the MRI evaluation of moyamoya disease (MMD). These include high-resolution volumetric imaging, high-resolution vessel wall characterization, improved cerebral angiographic and perfusion techniques, high-field imaging, fast scanning methods, and artificial intelligence. This review discusses the current state-of-the-art MRI applications in these realms, emphasizing key imaging findings, clinical utility, and areas that will benefit from further investigation. Although these techniques may apply to imaging of a wide array of neurovascular or other neurological conditions, consideration of their application to MMD is useful given the comprehensive multidimensional MRI assessment used to evaluate MMD. These MRI techniques span from basic cross-sectional to advanced functional sequences, both qualitative and quantitative.

The aim of this review was to provide a comprehensive summary and analysis of current key relevant literature of advanced MRI techniques for the evaluation of MMD with image-rich case examples. These imaging methods can aid clinical characterization, help direct treatment, assist in the evaluation of treatment response, and potentially improve the understanding of the pathophysiology of MMD.

Authors: Lili Purwati  , Ismeddiyanto  , Yuniarto Enno
Published: December 2019

Kuat tekan dan kuat tarik belah adalah parameter penting kekuatan beton. Penelitian ini dilakukan untuk mengkaji pengaruh penggunaan Natrium Tripolyphosphate (Na5P3O10) terhadap sifat mekanik beton cor di dalam air Under-Water Concrete (UWC). Variasi Na5P3O10 yang digunakan adalah 5%, 10% dan 15% terhadap berat semen, serta penambahan filler berupa abu batu dengan presentase 10% terhadap berat agregat halus. Nilai kuat tekan dan kuat tarik belah diperoleh dengan pengujian laboratorium dengan benda uji beton silinder ukuran 10 x 20 cm. Hasil penelitian menunjukkan kuat tekan dan kuat tarik belah beton paling rendah terjadi pada variasi Na5P3O10 5% yaitu 5.96 MPa. Kuat tekan dan kuat tarik belah beton tertinggi yakni pada variasi Na5P3O10 10% sebesar 12.13 MPa, namun terjadi penurunan pada beton variasi Na5P3O10 15% yakni 9.27 Mpa. Hasil penelitian tersebut menunjukkan bahwa presentase Na5P3O10 5% menurunkan kuat tekan dan kuat tarik belah karena besarnya segregasi pada beton, sedangkan presentase Na5P3O10 15% justru mengurangi nilai workability beton segar sehingga tidak dapat memadat sendiri dengan baik. Penggunaan Na5P3O10 pada penelitian ini menunjukkan bahwa selanjutnya Na5P3O10 dapat digunakan sebagai Anti Washout Admixture pada Under-Water Concrete (UWC), namun memerlukan mix desain khusus Self Compacting Concrete dan pemilihan material penyusun, sehingga beton yang dihasilkan mencapai kekuatan rencana.
Sulfide mineralization of phoscorites and carbonatites of the guli massif (Polar Siberia) and potential of these rocks on noble metals

Published: December 2019

A first complex investigation of mineral forms of Au and Ag and distribution of noble metals in sulfide-containing phoscorites and carbonatites, their magnetite and sulfide concentrates of alkaline ultrabasic massif Guli (Polar Siberia) was made by neutron activation method, XRF and microprobe analyses. Sulfide concentrates of carbonatites are enriched with Pt up to 2.93, Au up to 61.6 and Ag up to 3.61 (ppm).

The main sulfides are pyrrhotite, djerfisherite, chalcopyrite and pyrite. Silver is accumulated in the late chalcopyrite, Ag- djerfisherite, later ― lenaite, sternbergite or argentopyrite and native silver. Wide dissemination of djerfisherite in phoscorites and carbonatites and defined inclusions of rasvumite, K-Na-Ca carbonates, carbocernaite and strontianite in pyrrhotite, is the evidence of of high activity of K, Na, Sr, LREE, F, Cl and S during the sulfides crystallization. Chlorine has a high capacity for the formation of chlorine-silver complexes and is probably an agent for the transfer of noble metals in carbonatites.

The comparison of surveyed associations with published experimental data shows that formation of sulfides starts at the temperature no lower than 500С (early pyrrhotite) and lasts till 150C (argentopyrite). The late carbonatite assemblages may can be enriched with Au and Ag and be a potential source of formation of alluvial gold.
Sedimentation rates (data on 210pb and 137cs radionuclides) in different facial-genetic types of the Kara sea bottom sediments
Authors: Rusakov V. Yu. , Borisov A. P. , Solovieva G. Yu.
Published: December 2019

In the article original data on isotope composition of natural excess Pb-210 and artificial Cs-137 radionuclides in upper 2550-cm layer of sea-bottom sediments at the Kara Sea (from Ob and Yenisei estuaries, Eastern-Novaya-Zemlya trough, Voronin trough, as well as Sedov bay (Novaya Zemlya)) are presented. The research results showed close tie between sedimentation rates and facial-genetic types of the sea-bottom sediments. Highest sedimentation rates are typical for the terrigenic-estuarine type. The type is divided on tractional load with sedimentation rate 0.40.7 cm per year and mud bank sediments with sedimentation rate 0.71.0 cm per year. The terrigenic-shallow-marine type is characterized by lowest sedimentation rate 0.10.3 cm per year. The background terrigenic-marine type has a broadest spectrum of the sedimentation rates: on trough slope the rates are minimal (likely to terrigenic-shallow-marine type), within central parts of the trough (as a result of gravity creep) the rates may increase up to 0.9 cm per year. Single facial-genetic type is glacial sediments of Navaya Zemlya bays. Measured recent sedimentation rate within inner depression of the Sedov bay is 0.10.2 cm per year.

Published: December 2019

Flywheel is a rotating mechanical device, which is generally used on four-wheeled vehicles. Flywheel has a moment of inertia that is able to withstand changes in rotational speed. The energy in flywheel is mechanical energy. This mechanical energy will be converted by generators into electrical energy. At the flywheel-based power plant, tests are carried out in the form of rotation, the generator power of the generator under no load or load conditions, and the time needed for this generator to survive. The results showed that the ability of the flywheel-based power plant in the condition without a backup supply to the motor in the condition of a generator without a load is able to generate power of 860.1 W for 22 seconds, while in a load-bearing generator capable of generating electricity by 708.75 W for 18 secondsÂ
Stressful Life Events and Racial Disparities in Cognition Among Middle-Aged and Older Adults
Authors: Zuelsdorff Megan , Okonkwo Ozioma C. , Norton Derek , Barnes Lisa L. , Graham Karen L. , Clark Lindsay R. , Wyman Mary F. , Benton Susan F. , Gee Alexander , Lambrou Nickolas , Johnson Sterling C. , Gleason Carey E.
Published: December 2019

Background:

It is well-documented that African Americans have elevated risk for cognitive impairment and dementia in late life, but reasons for the racial disparities remain unknown. Stress processes have been linked to premature age-related morbidity, including Alzheimer’s and related dementias (ADRD), and plausibly contribute to social disparities in cognitive aging.

Objective:

We examined the relationship between stressful life events and cognitive decline among African American and White participants enrolled in the Wisconsin Registry for Alzheimer’s Prevention (WRAP).

Methods:

Linear mixed models including demographic, literacy, and health-related covariates were used to estimate (1) relationships between a life event index score and decline in cognitive test performance in two domains of executive function (Speed & Flexibility, Working Memory) and one domain of episodic memory (Verbal Learning & Memory) among 1,241 WRAP enrollees, stratified by race, and (2) contributions of stressful life events to racial differences in cognition within the full sample.

Results:

African Americans (N = 50) reported more stressful life events than Whites (N = 1,191). Higher stress scores associated with poorer Speed & Flexibility performance in both groups, though not with declines across time, and partially explained racial differentials in this domain. Among African Americans only, stressor exposure also associated with age-related decline in Verbal Learning & Memory. Stressor-cognition relationships were independent of literacy and health-related variables.

Conclusions:

Greater lifetime stress predicted poorer later-life cognition, and, in a small sample of African Americans, faster declines in a key domain of episodic memory. These preliminary findings suggest that future work in large minority aging cohorts should explore stress as an important source of modifiable, socially-rooted risk for impairment and ADRD in African Americans, who are disproportionately exposed to adverse experiences across the life course.
Is Aquatic Therapy Optimally Prescribed for Parkinson’s Disease? A Systematic Review and Meta-Analysis
Authors: Carroll Louise M. , Morris Meg E. , O’Connor William T. , Clifford Amanda M.
Published: December 2019

Background:

Aquatic therapy offers an alternative physiotherapy approach to managing the motor and non-motor symptoms associated with Parkinson’s disease (PD).

Objective:

This review examined exercise prescription for aquatic therapy in PD and evaluated if aquatic therapy is as effective as land-based physiotherapy for improving movement, disability and wellbeing in people living with PD.

Methods:

A systematic search of eight databases was conducted to identify suitable randomized controlled trials from inception until August 2019. Aquatic therapy prescription data and outcomes of interest included gait, balance, motor disability, mobility, falls, mood, cognitive function and health related quality of life data was extracted and synthesised. A meta-analysis was performed where appropriate.

Results:

Fourteen studies involving 472 participants (Hoehn & Yahr scale I–IV) met the inclusion criteria. Eight were of modest quality, scoring 70–80% on the PEDro scale. Seven studies were included in the meta-analysis. Exercise prescription was highly variable and often insufficiently dosed. Similar gains were shown for aquatic therapy and land exercises for balance, motor disability or quality of life. A statistically significant difference was found for mobility as measured using the TUG (–1.5 s, 95 % CI –2.68 to –0.32; p = 0.01, I2 = 13%), in favor of aquatic therapy.

Conclusion:

Aquatic therapy had positive outcomes for gait, balance and mobility that were comparable to land-based physiotherapy in the early stages of PD. The optimal dosage, content and duration of aquatic interventions for PD could not be confirmed in this meta-analysis. Many trials appeared to be under-dosed and therapy duration was low, ranging from 3–11 weeks.
Ten Years of the International Parkinson Disease Genomics Consortium: Progress and Next Steps
Authors:   The International Parkinson Disease Genomics Consortium (IPDGC)
Published: December 2019

In June 2009 a small group of investigators met at the annual Movement Disorders Society meeting in Paris. The explicit goal of this meeting was to discuss a potential research alliance focused on the genetics of Parkinson disease (PD). The outcome of this informal meeting was the creation of the International Parkinson Disease Genomics Consortium (IPDGC), a group focused on collaborative genetics research, enabled by trust, sharing, and as little paperwork as possible. The IPDGC has grown considerably since its inception, including over 100 scientists from around the World. The focus has also grown, to include clinical and functional investigation of PD at scale. Most recently, the IPDGC has expanded to initiate major research efforts in East Asia and Africa, and has prioritized collaborations with ongoing major efforts in India and South America. Here we summarize the efforts of the IPDGC thus far and place these in the context of a decade of progress in PD genomics. We also discuss the future direction of IPDGC and our stated research priorities for the next decade.
Adaptive VIRE indoor positioning algorithm based on Kriging interpolation
Authors: Wang Haitao , Chen Yanli
Published: December 2019

In traditional VIRE method, the linear interpolation is used to estimate the relationship between RSSI and distance, this increases the positioning error. Moreover, the label elimination threshold is a fixed value that is obtained by repeated adjustment experiments, this increases the time complexity of positioning. For these two problems, an adaptive VIRE indoor positioning algorithm is proposed based on Kriging interpolation. The Kriging interpolation is used to estimate the RSSI value of the virtual tag, and the threshold is automatically adjusted according to the real-time characteristics of the pending tag, so that the number of adjacent tags is nearly optimal, and the interference is more accurately eliminated, thereby the positioning coordinates are obtained. The experimental comparison results show that the algorithm not only saves the positioning cost, but also improves the positioning accuracy.

Published: December 2019

Regenerative medicine with the use of stem cells has appeared as a potential therapeutic alternative for many disease states. Despite initial enthusiasm, there has been relatively slow transition to clinical trials. In large part, numerous questions remain regarding the viability, biology and efficacy of transplanted stem cells in the living subject. The critical issues highlighted the importance of developing tools to assess these questions. Advances in molecular biology and imaging have allowed the successful non-invasive monitoring of transplanted stem cells in the living subject. Over the years these methodologies have been updated to assess not only the viability but also the biology of transplanted stem cells. In this review, different imaging strategies to study the viability and biology of transplanted stem cells are presented. Use of these strategies will be critical as the different regenerative therapies are being tested for clinical use.

ГЛОБАЛЬНЕ ГРОМАДЯНСЬКЕ СУСПІЛЬСТВО, ДЕМОКРАТІЯ ТА ПРИНЦИПИ СУДОЧИНСТВА
Authors: Музичук К. С.
Published: December 2019

Статтю присвячено висвітленню принципів судочинства, завдяки яким ЄСПЛ відстоює ідеї демократії.

Обґрунтовано, що глобальне громадянське суспільство сприяє поширенню демократич­них цінностей. До цінностей глобального громадянського суспільства належать демокра­тичні принципи судочинства, адже саме вони забезпечують захист демократії. Запропоно­вано визначення демократії. Здійснено структурно-логічний аналіз вітчизняних принципів судочинства з тими, які лежать в основі роботи Європейського суду з прав людини. Запро­поновано кілька дефініцій демократичних принципів судочинства. Демократичні принципи судочинства - це основні засади діяльності ЄСПЛ, якими він керується під час захисту конвенційних прав і свобод людини і які допускають їх обмеження тільки в межах демокра­тії. Демократичні принципи судочинства - це сукупність правових ідей захисту конвенцій­них прав і свобод людини, порядок реалізації яких у суді регулюється рамками демократії.

ПРАВО І СВОБОДА ЯК ЦІННІСНІ КАТЕГОРІЇ РОЗВИТКУ ГРОМАДЯНСЬКОГО СУСПІЛЬСТВА В УКРАЇНІ
Authors: Магновський І. Й.
Published: December 2019

Стаття присвячена висвітленню у загальнотеоретичному контексті таких ціннісних ка­тегорій, як право і свобода, що утворюють фундаменталізуюче і сутнісне підґрунтя для розвитку громадянського суспільства в Україні в умовах викликів сьогодення. Зосереджено увагу на різноманітних аспектах осмислення феномена права та свободи, котрі закладе­ні в основу формування громадянського суспільства, що розглядалися у працях вчених правознавців. Визначено ряд значущих властивостей права, зокрема: загальнообов'язко­ву нормативність, формальну визначеність, високу державну забезпеченість та інші, які розкривають його місію істотної соціальної сили суспільства. Розкрито основні формальні цінності права, які виявляються у трьох площинах: право має здатність забезпечити загаль­ний стійкий порядок у суспільних відносинах; можливість досягти визначеності, точності в самому змісті суспільних відносин; здатність домогтися гарантованого результату. Наголо­шено, що право у життєдіяльності суспільства та людини виступає як основа його самотво-рення в історії, як форма реалізації творчості людини, як гарантія свободи й відмежування від варварства та несправедливості. Вказано на ефективну самоорганізацію суспільства завдяки упорядкуванню свободи, де потужним її засобом є право, яке й визначає розумну міру свободи. Означено сутність природного призначення свободи, яка є моментом права, формою вираження соціальної реальності засобами і логікою правосвідомості, втіленням самодостатності та індивідуальності кожного. Акцентовано увагу на сутності громадянсько­го суспільства, яка полягає у забезпеченні законних прав людини, де у його реальності є умовою практичної реалізації ідеї права як свободи.
СТРУКТУРА АДМІНІСТРАТИВНИХ ТА АДМІНІСТРАТИВНО-ПРОЦЕСУАЛЬНИХ ПРАВОВІДНОСИН
Authors: Золотухіна Л. О.
Published: December 2019

У статті досліджено структуру адміністративних та адміністративно-процесуальних правовідносин. Автором зроблено висновок про те, що сутність розуміння публічного ін­тересу повинна охоплюватися встановленням кола існуючих об'єктивних потреб, задово­лення яких має забезпечуватися засобами публічної влади. Обґрунтовано, що реалізація адміністративно-правових відносин є неможливою поза існуванням тісного взаємозв'язку суб'єктів із приводу задоволення ними своїх або інших інтересів і потреб, які опосеред­ковують об'єкти адміністративно-правових відносин. Автором зроблено висновок про те, що без належного виконання визначених чинним законодавством юридичних обов'язків в адміністративному праві є неможливим забезпечення публічних інтересів. Підкреслюєть­ся, що належне забезпечення реалізації публічного інтересу визначає рівень ефективності функціонування органів державної влади й місцевого самоврядування, характеризує рівень розвитку суспільства. Автором акцентовано увагу на тому, що задоволення публічного інтересу визначає пріоритет діяльності органів державної влади та місцевого самовряду­вання. Зазначено, що ефективність реалізації адміністративних правовідносин залежить від ефективності механізму публічного управління, активізації впровадження адміністратив­но-правових методів заохочувального характеру, удосконалення системи засобів державно­го соціального примусу.

Published: December 2019

Background. The results of the treatment of young children who are on artificial lung ventilation in the departments of anesthesiology and intensive care (DAIC) depend directly on the antibiotic therapy policy used in the department.

Aim. Analysis of the etiological structure and the level of antibiotic resistance of pathogens of nosocomial pneumonia (NP) in young children in the conditions of the DAIC of the Regional Children’s Clinical Hospital № 1 in Kharkov for the period 2000-2018.

Materials and methods. 89 children with nosocomial pneumonia who were undergoinig artificial lung ventilation in the anesthesiology and intensive care unit up to 3 year-olds.

Results. Gram-negative microorganisms (MOs) were isolated in 84.3% (n=75), gram-positive MOs – in 12.35% (n=11), micosis of different species in 3.37% (n=3). The study of antibiotic resistance of strains of microorganisms isolated from endotracheal aspirate in infants with nosocomial pneumonia, significantly indicates the predominance in the structure of pathogens of gram-negative microorganisms having multiple or panresistant microorganisms

Conclusions. Carrying out regular monitoring of antibiotic sensitivity will allow more flexible implementation of antibiotic therapy policy in the DAIC, which, in turn, will increase the effectiveness of treatment, will reduce the economic costs and mortality of this contingent of patients.

LEARNERS’ VIEWS ON ASYMPTOTES OF A HYPERBOLA AND EXPONENTIAL FUNCTION: A COMMOGNITIVE APPROACH
Authors: Mudaly Vimolan , Mpofu Sihlobosenkosi
Published: December 2019

Learners in South African schools often respond poorly in questions related to the asymptote. Despite the fact that there are only a few functions in the South African curriculum that actually explore the asymptote, learners still show some deficiency in their understanding of the concept. This research examined Grade 11 learners’ mathematical discourses about the asymptotes of the hyperbola and exponential functions. Data were analysed using the Realisation Tree of a Function, an adaptation of the Realisation Tree Assessment tool from Weingarden, Heyd-Metzuyanim and Nachlieli. While the Realisation Tree Assessment tool focused on teacher talk, the Realisation Tree of a Function focused on learner expression and responses. A qualitative research design was essentially adopted, with exploratory, descriptive and interpretive elements complementing both its data collection and analysis. A purposive sampling strategy was implemented. Data were collected by means of a test administered to a total of 112 Grade 11 participants from four selected secondary schools. Focus group interviews were conducted with 24 of the best-performing participants by using their responses from the written mathematical tests. The results revealed that the learners’ mathematical discourse is not coherent. While learners’ work on each representation was often mathematical there seemed to be a struggle when the task had an unusual orientation. Different expressions of the same mathematical object elicited different responses. The challenge is that learners exhibited a fragmented relationship between the mathematical objects of the function. Keywords: commognition, realization tree, ritualised learning, visual mediators.
INDUCTION OF WOMEN BEGINNER TEACHERS AT TWO SOUTH AFRICAN COMMUNITY SECONDARY SCHOOLS
Authors: Ngwira Happy , Potokri Onoriode Collins
Published: December 2019

The quest of beginner teachers becoming experienced teachers remains a major issue within the educational terrain. Induction experience(s) of beginner teachers particularly women in selected community secondary schools in South Africa was the focus of this research. In this research, the problems that women beginner teachers face at some selected schools, as well as the types of induction programmes used to support them, as they grappled with the problems, were explored. A qualitative research approach involving semi-structured interviews and non-participant observation was used in the collection of the requisite data. A sample comprising two community secondary schools and four women beginner teachers were selected to take part in the research. To make meaning of the data which were collected, inductive analysis of the data was conducted. Communities of Practice was used as the theory that underpinned the research findings reported in this paper. Based on the data analysis and the communities of practice theory that served as the framework, the paper among other findings reports that induction programmes used in sampled/selected schools were highly ineffective in supporting the women beginner teachers to overcome the problems revealed. The research contributes to the body of knowledge on the lived experiences of beginner teachers at the beginning of their teaching career and provides recommendations on classroom management and dealing with ill-disciplined learners.
Keywords: beginner teacher; community practice; education leadership; teachers’ induction; women teacher.
Pertumbuhan Kesadaran dalam Agama
Authors: Sihombing Edy Syahputra
Published: December 2019

Salah satu ancaman serius dalam peradaban millennium ketiga ini adalah kecenderungan agama-agama yang hanya berorientasi pada paradigma rumusan-rumusan doktrinal konseptual yang sempit. Ironisnya, agama-agama yang harusnya menyebarkan perdamaian justru menjadi potensi sumber konflik. Situasi tersebut memunculkan keterpisahan antara manusia dengan manusia lainnya bahkan dengan yang ilahi. Akan tetapi evolusi peradaban masih menyadari ada banyak hal yang penting dalam tradisi spiritual agama-agama untuk membangun peradaban. Di sini agama-agama perlu meredefinisikan kembali eksistensinya dalam peradaban, memperluas horizon paradigma model religius-spiritualitas dalam konteks yang beragam dan berorientasi pada pertumbuhan kesadaran akan kesatuan realitas yang universal saling terkait satu sama lain.
