red-emissive CdSe/ZnS quantum-dot light-emitting diode (QLED) in visible light communication (VLC). The light emitted from the 60°-designed QLED transmits in free space with a data rate of 4 Mb/s at a 3 m transmission distance by using a simple modulation scheme of non-return-to-zero on-off keying. The maximum data rate of 2.5 Mb/s with a bit error rate below the forward-error-correction (FEC) limit is achieved with the optical angles of

. The influences caused by the voltage, distance, and optical angle of emitting light are taken into consideration during communication. The performance of the QLED-based light source compares favorably with other solution-processed devices in efficiency, luminance, bandwidth, transmission speed, and distance. Additionally, to the best of our knowledge, this is the first report of an investigation on the application of QLED in VLC. Our results should be instructive for further investigation on QLED communication.
Diabetic retinopathy: a tool for cardiovascular risk stratification
Authors: Avogaro Angelo , Fadini Gian Paolo
Published: January 2020

Randomized, cross-sectional, and prospective studies have demonstrated that microvascular complications in patients with diabetes are not only the cause of blindness, renal failure and non-traumatic amputations, but also powerful predictors of cardiovascular complications. The pathophysiology of diabetic microvascular complications is determined by several factors including epigenetic modifications, and reduced release of circulating progenitor cells by the bone marrow. Identifying microvascular complications, in particular retinopathy, increases the ability to stratify patients in terms of cardiovascular risk. There may no longer be a rational to consider microangiopathy and macroangiopathy as entirely separate entities, but they should most likely be viewed as a continuum of the widespread vascular damage determined by diabetes mellitus.

Reason and Narration with Ibn Rushd (Averroes)
Authors: Khattab Mohammad Ali
Published: January 2020

Ibn Rushd was distinguished by his bewildering personality, stemming from being a jurist and theologist, a philosopher and physician, and an astronomer. When researching his writings, we found that he encourages a lot of reason, and puts aside everything related to revelation, at other times, you find him defending Revelation and does not care about the mind, and you see him attacking the Asha’ries. In some cases, he defends them in other places, and in some cases, he adopts the views of the predecessor, making him a collector of all contradictions. However, the beholder in his biography and history knows that he went through several stages, stamped with jurisprudential stability, moderation in judging the opponents, and a victory for the doctrine of Tafweedh.

Authors: Nasreen Shahida , Shah Madiha
Published: January 2020

Research in the area of school leadership proves that effective leaders accomplish the role of instructional leaders (Zheng, 1996). The main objective of an effective principal is the supervision of classroom instructions (Hoy, & Hoy, 2006). This paper examines the effect of instructional supervisory practices of the school leaders on teacher motivation in private secondary schools of Lahore, Pakistan. Twenty four schools from three different school types (low-income schools, middle-class schools, and elite schools) were selected using stratified random sampling. A questionnaire comprising of two scales, Instructional Supervisory Practices Scale (ISPS) and Work Extrinsic and Intrinsic Motivation Scale (WEIMS), was used to collect data from 530 teachers. Descriptive as well as inferential statistics were used to obtain results. The teachers’ perceptions regarding their leaders’ instructional supervisory practices and the level of teacher motivation were determined by computing mean and standard deviation. The Pearson Correlation (r) was computed to explore the relationship between six sub-scales of instructional supervisory practices and teacher motivation. The results of the study indicated a significant positive relationship between instructional supervision and teacher motivation. It is concluded that instructional supervision significantly contributes to teacher motivation.

Published: January 2020

The paper determines whether the students’ career aspirations have changed from the time they enrolled for a particular programme during the first year until they have encountered socialisation throughout the four-year learning period, which includes the internship programme. Descriptive research design was used in the study. The research population for the study were all final year University Botswana undergraduate business students on a four year study programme. Purposive sampling was used to select a total of 100 students from the final year Accounting and Finance students and, the two groups being equally represented in the sample. Primary data was used for the study and collected using a 5-point Likert scale questionnaire from the two groups during class time. Descriptive statistics and Independent sample t-tests were used to analyse the data. The internship programme is an eye opener to the students and help them to prepare for their careers. The students who enrolled for the accounting and finance programmes stuck to the careers choices they had made at the commencement of their four year study programmes. The university must continue with internship programmes, if possible assist finance students to secure internship places in finance related institutions both locally and regionally.

The current study presents an account of mathematics and science knowledgebase of private Gaborone preschool teachers and assesses its influence on their classroom teaching. It assesses their Subject Matter Knowledge (SMK) and Pedagogical Content Knowledge (PCK) and scales their views on the Best Practices for mathematics and science teaching in preschools. A pragmatic paradigm with a concurrent mixed-method mode was used to conduct this study. Using a random-purposive sampling procedure, 64 preschool teachers were selected. Questionnaire and focus group discussions were used for data collection. The quantitative data was analysed using descriptive analysis and presented with the help of frequency Tables and Graphs. The qualitative data was coded and synthesised to receive meaningful information. The findings show that 80% of teachers were trained as primary school teachers; only 14% had professional training in Early Childhood Education (ECE). It further revealed that the teachers had SMK; however, were less proficient in PCK which affected their classroom practices, despite having ample material resources. The preschool teachers viewed the establishment of the Science Center/s for young children and strong administrative support as best practices for teaching mathematics and science in preschools.
Effectiveness Of Forest Management As Affected By The Land Use Act In Onigambari Forest Reserve, Oluyole Local Government Area Ibadan, Nigeria.
Authors: Yusuff Z .O. , Alamu L. O.
Published: January 2020

The growing demands for forest goods and services are putting serious pressure on the resource base, leading to over-exploitation and subsequent forest degradation. In Nigeria both natural and plantation forests could not meet 100 million m3 of the 180 million m3 wood demand in 2000. At present, one of the most challenging problems facing the country is the production of sufficient food and fiber to meet the needs of the ever-increasing population (Peters, 2005). This study examined the effectiveness of forest management in Onigambari forest reserve, Oluyole Local Government Area Ibadan, Nigeria. The study employed a simple random sampling technique to select 43 forest farmers randomly. Descriptive tools such as frequency distribution, percentage, mean, ranking and Pearson product moment correlation (PPMC) was used as inferential statistical tool to determine the forest management performance in the study area while Student T-test was used to test for the significance difference of the relationship between the forest managers and locals. Result showed that mean age of respondents is 39.65 years. A tittle above Forty Eight percent of the respondents were females while 51.16% of the respondents were males, A tittle above Eighteen percent of the respondents were single while 81.40% of the respondents were married. The result of Student t- test revealed that the mean of age is higher than the mean total effects indicating improved performance of age on the total effects in the study area. The p value (0.0000) is smaller than the chosen alpha value (0.05) which has the t-value of 6.840. The result further revealed that deforestation is now becoming history as a result of land use policy on forest management and it has the highest weighted mean score of  2.86 and ranked as the first, followed by the demand of local industries can partially be met second (WMS= 2.74). The result on Pearson product moment correlation revealed that some of the selected factors such as poor participation of people involved in forestry (r= 1.000**; p <= 0.01), use of inexperience foresters (r= 0.262*; p <0.05) and poor conflicts management between local farmers and foresters (r= 0.387*; p < 0.05) respectively exhibited a significant relationship between forest managers and locals/indigenous people. The study recommended that there should be increase in communication among all stakeholders to ensure the harmonization of all interests towards a better use of forest resources, also effective continuous public enlightenment is essential to secure the interest and participation of farmers with an effective mechanism for good governance, equitable benefit sharing, and lastly, conflict resolution mechanism should be established.
Tackling Gender poverty relations within Households through micro-credit Programs in Uganda
Authors: Busingye John
Published: January 2020

The study mainly set out to investigate the factors that influence gender relations in Uganda.  This paper contributes to the body of knowledge by determining the local gender context influencing  gender  poverty relations in the face of micro-credit programs and practices in Uganda. The study was grounded on the feminist conflict theory. Women accessing and utilizing microcredit programs from Savings and Credit Cooperative Organizations (SACCOs) in Mbarara (MM) and Bushenyi-Ishaka Municipalities (BIM) of South West Uganda provided the contextual setting of the study.

Data was collected from a total of 198 respondents by use of interviews and focused group discussions. The study findings show that age, women’s marital status, the level of formal education, number of children depending on women, assets for collateral and signature requirements were the main factors influencing gender poverty relations within households in Uganda. The study contends that poverty and gender relations influence access to microcredit programs.  The study then recommends that SACCOS should formulate gender inclusive strategies like alternative means of collateral and introduce women friendly modes of access to microcredit services as a strategy for tackling poverty among women in Uganda. The government is also advised to sensitize the public about gender poverty  relations, human rights and increasing household income using the available media.

Nikolai Leskov in the aspect of translation: language game and phraseology
Authors: Seliverstova Elena
Published: January 2020

The continuing interest in the artistic word reveals all the new aspects of the study of the writers’ language, the methods of usage of the linguistic units in their works. This article brings together in one focus several problems: the study of the language creativity of N.S. Leskov, manifested in the creation of unforgettable speech portraits of characters, who, in search of expressiveness, realize their creative abilities, using already known words and expressions or creating the new ones. Occasional expressions, used to achieve maximum expressiveness and intensity of the transmitted value, can be read in the same text in different ways. The multiple transformation of stable expressions is especially typical for the writer, therefore it is difficult not only to interpret the author’s phraseology in Leskov’s works, but also to translate. The Czech translators using the principle of functional similarity try to keep ways of usage of the units created by the author and to inform the reader of expressivity, emotional sounding and esthetic functions of the original.
Eufemizacja w przekładzie (na materiale języka czeskiego)

Published: January 2020

Niniejszy artykuł dotyczy zagadnienia eufemizacji w przekładzie z języka czeskiego na polski. Materiał badawczy został wyekscerpowany z czeskojęzycznej literatury pięknej za pośrednictwem korpusu językowego InterCorp, stanowiącego integralną część Czeskiego Korpusu Narodowego i dającego możliwość analizy tekstów pod względem ekwiwalencji przekładowej.

   Autor skoncentrował swoją uwagę na sposobach przekładu dwóch wybranych leksemów (srát, děvka) oraz wyrażenia przyimkowego (do prdele), które są rejestrowane w słownikach języka czeskiego z kwalifikatorem wulgarności lub grubiańskości. Analiza wykazała, że większość tłumaczy dokonuje tzw. „higienizacji przekładu”, unikając bezpośredniej ekwiwalencji kłopotliwych leksemów przy zastosowaniu procesu eufemizacji, czego rezultatem nie zawsze jest jednak eufemizm sensu stricto (jednostka leksykalna).

W prezentowanym artykule została podjęta próba ustalenia przyczyn powodujących omawiany proces.

Published: January 2020

In this article I analyze the interface of The Witcher 3: Wild Hunt with regard to its transparency as well as its influence on the player’s  immersion. Furthermore, I scrutinize all measures used by the interface to decrease the effect of emersion, which might appear as game information is being read by the player. I also consider the literary context in my research – I reflect on how the interface refers to Andrzej Sapkowski’s Witcher cycle and how these references have been implemented in the interface structure.
Glitch as the Representation of the Uncanny in Oxenfree (2016)
Authors: Waszkiewicz Agata
Published: January 2020

The Gothic engages its audiences in the constant play by evoking the same anxieties in its audience and its protagonists. Furthermore, it could be argued that transgressions are its immanent feature. The supernatural elements, with the strong emphasis on the ghosts, often create the feeling of the uncanny, which, defined by the mixing of the familiar with unfamiliar, is not unknown to the video game genre. In the paper I offer a close reading of Oxenfree (2016), demonstrating the Gothic elements featured in the game, concentrating on how the uncanny manifests through the use of the audiovisual glitch.
Perma-dying Worlds and the Limit of Eternal Return in Digital Games

What Characterizes Chinese Students’ Exposition Besides Deduction and Induction?: A Comparative Rhetoric Perspective
Authors: Liu Donghong , Gan Qiong
Published: January 2020

Rhetorical features of Chinese writers’ essays have been studied for decades but inconsistent interpretations of deduction and induction lead to controversial results. Taking a comparative rhetoric perspective, this paper clarifies the notions of deduction and induction and investigates what rhetorical features characterize Chinese expository paragraphs besides deduction and induction and whether Chinese EFL learners’ English paragraphs have similar features. Two kinds of data sources were used—29 full-score Chinese expositions in College Entrance Examinations and 29 English expositions written by Chinese EFL learners. The results show that deduction is preferred in both Chinese and EFL writing, and that rhetorical paragraphs and coordinate paragraphs are particular to Chinese writing while the EFL learners’ paragraphs display hybrid rhetoric such as semi-coordination. It is concluded that neither Chinese paragraphs nor EFL ones are similar to the modern English rhetorical paradigm, and English rhetoric instruction will facilitate the introspection of the two kinds of rhetoric.
Scaffolding Students’ Self-Assessment of Their English Essays with Annotated Samples: A Mixed-Methods Study
Authors: Xu Ying
Published: January 2020

This paper aims to investigate the effectiveness of rubric-referenced student self-assessment (SSA) on students’ English essay writing by employing a two-group pre-post-quasi-experimental research design. The method was tested on 54 students at a Chinese university. During a 17-week experiment, the experimental group (EG) received the rubric and annotated samples, while the comparison group (CG) received only the rubric in self-assessment. Data sources included students’ scores in the pre-test and post-test and interviews. Quantitative findings indicated that the EG made significantly stronger progress than the CG in the post-test. Interview results suggested that annotation-based rubric-referenced SSA can help students understand the task requirements, initiate their self-regulatory behaviors, and improve their self-assessment confidence, although students still wanted to receive assistance from teachers partly due to the Confucian-heritage culture settings in China. The findings are discussed in terms of the design features of sample annotations within the framework of self-regulated learning (SRL), as well as the implications of using this method in the classroom.

The effect of a scheduled regimen of acetaminophen and ibuprofen on opioid use following cesarean delivery
Authors: Poljak Dijana , Chappelle Joseph
Published: January 2020

Objective

The primary objective was to evaluate if the administration of ibuprofen and acetaminophen at regularly scheduled intervals impacts pain scores and total opioid consumption, when compared to administration based on patient demand.

Methods

A retrospective chart review was performed comparing scheduled vs. as-needed acetaminophen and ibuprofen regimens, with 100 women included in each arm. Demographics and delivery characteristics were collected in addition to pain scores and total ibuprofen, acetaminophen and oxycodone use at 24, 48 and 72 h postoperatively.

Results

The scheduled dosing group was found to have a statistically significant decrease in pain scores at all time intervals. Acetaminophen and ibuprofen usage were also noted to be higher in this group while narcotic use was reduced by 64%.

Gaseous volume oxidation (voloxidation) of uranium mononitride (UN) and uranium monocarbide (UC) was investigated in the “NOx-air” atmosphere in the temperature range 298–673 K. It was shown that UN can be converted into uranium water-soluble compounds using an alternative oxidation atmosphere based on NOX-gases. UO3 and uranyl nitrates are the main products of the reaction. Maximum degree of the UN conversion to water-soluble compounds equal to 80 % was observed at the temperature 565 K. Products of the UC conversion are uranium oxides and oxihydroxides. The observed degree of the UC conversion into water-soluble compounds was less then 20 %.

Open spina bifida (OSB) is one of the most prevalent congenital malformations of the CNS that often leads to severe disabilities. Previous studies reported the volume and thickness of the neocortex to be altered in children and adolescents diagnosed with OSB. Until now, the onset and the underlying cause of the atypical neocortex organization in OSB patients remain largely unknown. To examine the effects of OSB on fetal neocortex development, we analyzed human fetuses of both sexes diagnosed with OSB between 11 and 15 weeks of gestation by immunofluorescence for established neuronal and neural progenitor marker proteins and compared the results with healthy controls of the same, or very similar, gestational age. Our data indicate that neocortex development in OSB fetuses is altered as early as 11 weeks of gestation. We observed a marked reduction in the radial thickness of the OSB neocortex, which appears to be attributable to a massive decrease in the number of deep- and upper-layer neurons per field, and found a marked reduction in the number of basal progenitors (BPs) per field in the OSB neocortex, consistent with an impairment of cortical neurogenesis underlying the neuronal decrease in OSB fetuses. Moreover, our data suggest that the decrease in BP number in the OSB neocortex may be associated with BPs spending a lesser proportion of their cell cycle in M-phase. Together, our findings expand our understanding of the pathophysiology of OSB and support the need for an early fetal therapy (i.e., in the first trimester of pregnancy).

Increase in blood–brain barrier (BBB) permeability is a crucial step in neuroinflammatory processes. We previously showed that N Methyl D Aspartate Receptor (NMDARs), expressed on cerebral endothelial cells forming the BBB, regulate immune cell infiltration across this barrier in the mouse. Here, we describe the mechanism responsible for the action of NMDARs on BBB permeabilization. We report that mouse CNS endothelial NMDARs display the regulatory GluN3A subunit. This composition confers to NMDARs' unconventional properties: these receptors do not induce Ca2+influx but rather show nonionotropic properties. In inflammatory conditions, costimulation of human brain endothelial cells by NMDA agonists (NMDA or glycine) and the serine protease tissue plasminogen activator, previously shown to potentiate NMDAR activity, induces metabotropic signaling via the Rho/ROCK pathway. This pathway leads to an increase in permeability via phosphorylation of myosin light chain and subsequent shrinkage of human brain endothelial cells. Together, these data draw a link between NMDARs and the cytoskeleton in brain endothelial cells that regulates BBB permeability in inflammatory conditions.

SIGNIFICANCE STATEMENTThe authors describe how NMDARs expressed on endothelial cells regulate blood–brain barrier function via myosin light chain phosphorylation and increase in permeability. They report that these non-neuronal NMDARs display distinct structural, functional, and pharmacological features than their neuronal counterparts.
From Tone to Tune—Carl Stumpf and the Violin
Authors: Kursell Julia
Published: January 2020

This article investigates the work of philosopher and experimental psychologist Carl Stumpf with a focus on embedding his scientific perspective in a practice of musicianship. Stumpf wrote in an autobiographical essay from 1924 that he had considered becoming a professional violin player before taking up the study of philosophy. I claim that the practice of learning and playing this instrument sheds light on his concept of music, and at the same time signals its relevance for nineteenth-century musical aesthetics. To carve out the role of Stumpf's musicianship, I propose a “psychoanalytic” approach of tone psychology in the sense of Gaston Bachelard. For this I read through Stumpf's writings to trace the function and role of practices like analyzing tones and tunes, memorizing and notating pitch and melody, and using related tools and techniques like phonography. This is held against a reconstruction of his mentioning of the violin and of the context of violin pedagogy in the mid-nineteenth century. In so doing, I hope eventually to sharpen the notion of tone in Stumpf and thereby to contribute to a better understanding of his concept of complex qualities as opposed to the notion of Gestalt in the generation of his students.

La fragmentación parlamentaria nacional y la reforma del sistema electoral de la Región de Murcia: ¿nuevas oportunidades para un partido regionalista?
Authors: Parra Gómez David
Published: January 2020

La fragmentación parlamentaria tras las elecciones generales de 2016, marcada por el descenso de los dos grandes partidos mayoritarios y la irrupción de nuevas formaciones políticas, ha hecho aún más patente la necesidad de contar con el apoyo de partidos políticos de ámbito autonómico a la hora de sacar adelante iniciativas políticas de carácter nacional, así como el enorme rédito que tal apoyo supone para los territorios donde de tales partidos cuentan con soporte electoral. Asimismo, la composición fragmentada de la Asamblea Regional de Murcia fruto de las elecciones autonómicas de 2015, en las que el PP perdió la mayoría absoluta que ostentaba, trajo consigo una trascendental reforma de la ley electoral murciana. Ambos factores han favorecido la creación y expectativas de éxito de nuevos partidos regionalistas en la Región de Murcia, cuyos intentos por tener un espacio en el sistema de partidos murciano, sin embargo, han resultado infructuosos por el momento.
Nivel de interacción de la comunicación de los partidos políticos españoles en redes sociales
Authors: Cea Esteruelas María Nereida
Published: January 2020

Las redes sociales juegan un importante papel en la difusión de mensajes, no solo durante periodos electorales, sino también en toda estrategia de comunicación política. El objetivo de este trabajo es analizar la comunicación de los principales partidos políticos españoles en las redes sociales desde el punto de vista de los estudios de recepción. Para ello se analiza la respuesta de la audiencia a los mensajes lanzados por partidos políticos durante un mes, en las cuatro principales redes sociales (Twitter, Facebook, Youtube e Instagram). Para tal fin, se utilizan dos métricas de análisis: interacción y porcentaje de engagement (entendiendo por tal el nivel de implicación, compromiso, o fidelidad de la audiencia) que logran los mensajes difundidos en las redes sociales analizadas.Las conclusiones del estudio sugieren que la marca política Vox es la que logra mayor visibilidad e impacto en redes sociales en España. Con respecto al uso de redes sociales, en el ámbito de la comunicación política, Instagram se consolida como la de mayor crecimiento y la que mayor viralidad logra dar a los mensajes analizados. Sin embargo, todavía no es la preferida por los partidos más tradicionales, tal y como lo muestra el perfil bajo de actividad que mantienen en esta red.

Sebagai disiplin ilmu yang memelihara kemajuan manusia, coaching secara alami sesuai untuk mendukung individu dalam memenuhi kebutuhannya dalam hal pemenuhan dan keberhasilan hubungan. Coaching digambarkan sebagai proses pengembangan manusia yang terstruktur, adanya interaksi yang fokus dan penggunaan strategi yang tepat, serta alat dan teknik untuk mempromosikan perubahan yang diinginkan dan berkelanjutan untuk kepentingan klien (Bachkirova et al., 2014). Proses coaching dapat mengeksplorasi kebutuhan dasar manusia untuk berhubungan, dengan cara mencari, mengembangkan dan menjaga hubungan dengan orang lain.International Coach Federation (ICF) mendefinisikan coaching sebagai “hubungan kemitraan dengan individu melalui proses kreatif yang ditujukan untuk memaksimalkan potensi personal dan atau profesional individu.” Coaching melibatkan proses kreatif dimana individu diajak untuk berpikir, menemukan ide-ide, dan membuat strategi. Coaching membuat individu sadar terhadap potensi dan kekuatan yang dimilikinya dan memiliki kemauan untuk memaksimalkan potensi tersebut. Melalui teknik mendengarkan, bertanya dan menggali, seorang coach membantu individu untuk menemukan potensi dan kekuatan dari dalam dirinya, yang diarahkan untuk mencapai suatu tujuan.
