Authors: Arora, P  , Idnani, D  
Published: October 2021

The present study aims at studying the impact of social media on socio-emotional well-being of children. The methodology used here was random sampling through snowballing technique. A sample of around 50 children aged 11-18 years was collected to understand their responses about their own socio-emotional well-being. The results of the study showed that people use social media for different reasons, but they also face a variety of challenges, from physical health to mental health issues, the most prominent of what is needed is gratitude, resilience, calmness, compassion, and the pursuit of hobbies, fitness, and one's own peace of mind and happiness.
Hacia la interacción de la empresa y la universidad
Authors: Sánchez-Piedrahita Liliana 
Published: October 2021

El desarrollo de un país, y del mundo en general, depende de la interaccíón de la empresa, la universidad y el gobierno: las tres principales fuentes de poder y guías de la comunidad. Estas deben unirse en sus propósitos y actividades, pero desafortunadamente, a veces la empresa se encuentra encasillada con numerosas regulaciones e imposiciones fiscales establecidas por el gobierno. De igual forma se descuida la educación general, en especial la universitaria, ignorando que el recurso humano es la clave del desarrollo y por tanto debe ser la inversión más importante y valiosa de cualquier país.
La terciarización alternativa de la economía colombiana ¿Un ideal o una realidad?
Authors: Cuadro-Gúzman Efrain 
Published: October 2021

El presente escrito aborda el tema de la Terciarización Alternativa de la Economía Colombiana, entendido este proceso, como el crecimiento del PIB Social de No Mercado. Es decir, responde a la tercera alternativa ante la disyuntiva: Actividades Económicas del Estado versus Actividades económicas del sector Privado de Mercado. Se presenta una aproximación conceptual dada la complejidad y heterogeneidad de las organizaciones sin fines de lucro que lo conforman. Se concluye a manera de hipótesis que abre una interesante línea de investigación, que dicho sector alternativo ha venido creciendo en términos absolutos, que ha venido creciendo también su participación porcentual en el PIB total, pero que se observa una preocupante tendencia marginal decreciente (ha venido creciendo pero cada vez crece menos) a lo largo de los años en estudio. A esta preocupación se le agrega que las cantidades absolutas y la tasa de participación, no obstante tener una tendencia creciente, aún sus registros son muy pequeños frente a la necesidad que tiene Colombia de contar con este tipo de entidades que, al cumplir con su Rol de Interfase, permitirían que los recursos y el producto de toda la economía, permee a toda la sociedad en búsqueda de una mayor justicia y equidad social. De otra parte se halló que la distribución geográfica en términos absolutos del PIB social de No Mercado en la geografía colombiana, es inequitativo, ya 'que los departamentos más "ricos" cuentan con el mayor PIB Social de No Mercado, mientras que en los más pobres este indicador es bastante exiguo. La hipótesis general se sintetiza entonces en afirmar que: "En Colombia el proceso de Terciarizacion Alternativa de la economía colombiana, no está en los niveles ideales, para poder esperar de él que cumpla el rol de interfase entre la disponibilidad de recursos y la población en condiciones de vulnerabilidad social económica y política, que requiere la situación crítica que vive la Nación. " Palabras Claves: Terciarización Ortodoxa, Terciarización Alternativa. PIB Social de No Mercado. Organizaciones sin fines de lucro. Rol de Interfase. Justicia y equidad social. Distribución geográfica del PIB social de No Mercado.

El turismo se ha definido de muchas formas. Sin embargo, puede afirmarse que es el conjunto de relaciones y fenómenos surgidos de los viajes y de las permanencias temporales de las personas que se desplazan principalmente por placer o recreación. Casi todos los países del mundo consideran al turismo como una actividad importante en la prosperidad nacional, por sus contribuciones sociales y económicas, como por ejemplo, la creación de empleos directos e ihdirectos y la generación de ingresos o divisas.
Comparison of Hurst exponent estimation methods
Authors: Hamza Amjad H. , Hmood Munaf Y. 
Published: October 2021

Through recent years many researchers have developed methods to estimate the self-similarity and long memory parameter that is best known as the Hurst parameter. In this paper, we set a comparison between nine different methods. Most of them use the deviations slope to find an estimate for the Hurst parameter like Rescaled range (R/S), Aggregate Variance (AV), and Absolute moments (AM), and some depend on filtration technique like Discrete Variations (DV), Variance versus level using wavelets (VVL) and Second-order discrete derivative using wavelets (SODDW) were the comparison set by a simulation study to find the most efficient method through MASE. The results of simulation experiments were shown that the performance of the methods is relatively close, except for the SODDW method was the most efficient in MASE.

EVALUATION OF DISABILITY MAINSTREAMING STATUS IN SELECTED PUBLIC HIGH SCHOOLS AND EMPLOYMENT INSTITUTIONS IN LIBERIA
Authors: Collins Edwina , Masiga Casper , Ngugi Daniel 
Published: October 2021

Purpose: The purpose of the study sought to evaluate the status of disability mainstreaming policy in education in selected public high schools and public employment institutions in Liberia.
Materials and Methods: The research design incorporates both quantitative and qualitative methods. Purposive sampling was used to select 125 respondents from students with disabilities, principals, human resource directors, employees with disabilities from public employment institutions and representatives from Persons with disabilities organizations. Quantitative data was collected through electronic data collection tools (Kobo/ Survey CTO) and transferred in Excel spreadsheets for descriptive analysis and comparison. Qualitative data was collected through key informant interviews and analyzed according to themes.
Results: The study established that although there are disability mainstreaming policies at public high schools and employment institutions there is limited awareness and understanding of these policies among students and employees with disabilities. Moreover, there was no defined disability mainstreaming strategies to serve as a benchmark to determine the success or failure of implementation. Findings also showed that persons with disabilities were still finding it difficult to secure employment since the 4% disability quota mandated by the government to enhance the employability of persons with disabilities is not adhered to by government institutions. Further analysis indicated that the perception of principals and human resource officers can reinforce barriers to mainstreaming disability in public high schools and employment institutions. The study also found that limited budgetary allocation for disability mainstreaming activities, limited awareness of disability mainstreaming, lack of coordination among various implementing agencies, lack of teacher training in disability mainstreaming pedagogy and unavailability of training materials for teachers and students for inclusive education were among factors contributing to gaps in disability mainstreaming in public high schools and employment institutions.
Unique contribution to theory, practice and policy: The study recommends that the Ministry of Gender, Children and Social Protection (MGCSP) which coordinates all disability mainstreaming activities along with the National Commission on Disability create more public awareness on disability in all public entities. Government should provide funding’s to public high schools and employment institutions to enable them to implement the disability mainstreaming policies. Disability focal persons should also be assigned to these institutions to coordinate and monitor implementation.
Description of Colombian Electricity Pricing Derivatives
Authors: Prabakaran Sellamuthu 
Published: October 2021

Electricity markets are becoming a popular field of research amongst academics because of the lack of appropriate models for describing electricity price behavior and pricing derivatives instruments. Models for price dynamics must consider seasonality and spiky behavior of jumps which seem hard to model by standard jump process. Without good models for electricity price dynamics, it is difficult to think about good models for futures, forward, swaps and option pricing. In this paper we attempt to introduce an algorithm for pricing derivatives to intuition from Colombian electricity market. The main ambition of this study is fourfold: 1) First we begin our approach through to simple stochastic models for electricity pricing. 2) Next, we derive analytical formulas for prices of electricity derivatives with different derivatives tools. 3) Then we extent short of the model for price risk in the electricity spot market 4) Finally we construct the model estimation under the physical measures for Colombian electricity market. And this paper end with conclusion.

Published: October 2021

В статье рассматриваются проблемы исследования и консервации объектов из обугленного дерева на примере фрагмента деревянного блюда, обнаруженного при исследовании помещения на северо-восточном склоне поселения Токсанбай (Бейнеуский р-н, Мангистауская обл.) в 2005 г. Раскопки проводились экспедицией Института археологии им. А.Х. Маргулана под руководством З. Самашева, при участии А.С. Ермолаевой в рамках государственного стратегического проекта «Культурное наследие». В статье на конкретном примере дана оценка действий специалистов-археологов; показаны этапы работы специалистов-реставраторов. Даются рекомендации по работе с предметами из деградированных материалов. При исследовании памятника археологами, как правило, проводится полный комплекс мероприятий по фиксации вещных объектов. Предметы из деградирующих материалов требуют особого подхода в извлечении и хранении. В полевых условиях исследователи, при проведении полевой консервации ослабленных предметов, используют подручные материалы, часто это химические составы и не всегда в наличии имеются нужные, применение которых целесообразно в конкретном случае. Деревянное блюдо из жилища поселения Токсанбай относится к категории «обугленное дерево». Предмет из древесины горел без доступа воздуха, его первоначальная структура разрушилась, однако воздействие огня, в данном случае, стало тем консервирующим фактором, который позволил частично сохранить форму предмета. После проведения комплекса консервационно-реставрационных работ блюдо помещено на хранение в фонды Национального музея Республики Казахстан (г. Нур-Султан).

Randomized solid state bulk functionalization of aramid fiber pulp and its application in elastomer compositions
Authors: Hanifa Sheik Mohammed , Venkatakrishnan Subrahmanian 
Published: October 2021

AbstractN‐oxydiethylene‐2‐benzothiazole sulphenamide (NOBS) dispersed in an inert (saturated main chain) rubber matrix (ethylene‐co‐propylene‐diene monomer [EPDM], as carrier to be dispersed later in a predetermined lower quantities) containing definite amount of pre‐dried aramid fiber pulp (AP) was subjected to internal thermal influence as heated through dielectric‐dielectric interaction in a laboratory microwave oven. The reactions of NOBS with aramid fiber pulp (on the surface and in the bulk) were characterized using XPS, TGA, FTIR, SEM, and mechanical properties. The objective was to confirm the efficacy of dielectric heating in situ and to promote functionality for bonding with rubber. The functionalization was considered to be provided by NOBS. One such chemical modification was found to be the generation of free ends in the AP and it was characterized by XPS. At the same time, there was no thermal degradation as confirmed from TGA studies. The rubber‐AP masterbatch (as previously prepared was dispersed) in different proportions in Butadiene‐co‐acrylonitrile rubber (NBR) and various characterizations related to plain rubber compound and in the cross linked states including fluid barrier properties and spring characteristics were found to record a significant improvement. The SEM micrographs showed that the fiber‐rubber cohesion and the rubber‐AP interaction are enhanced due to the proposed dielectric heating induced functionalization of AP.

Published: October 2021

AbstractBackground and objectivesAlthough bran‐enriched foods are rich in bioactive compounds, the bioaccessibility of these bioactive compounds and their antioxidant activity after digestion in Chinese steamed bread (CSB) are poorly understood. The effects of wheat debranning on the sensory quality of CSB and antioxidant activity after digestion were studied, in order to provide special foods with different bran content for the consumers with diverse healthy status.FindingsFor CSB, wheat debranning improved the color, textural properties, and sensory score but reduced the antioxidant activity and total phenolic content (TPC). After in vitro digestion, the TPC and antioxidant activity of the chyme‐soluble fraction (CSF) reached the highest value at degrees of debranning between 3% and 7%. Compared with debranning process, the effects of in vitro digestion on antioxidant activity were more significant.ConclusionsDegrees of debranning between 3% and 7% can offer the highest nutritional value of CSB. Although debranning process had some effects on the TPC and antioxidant activity of CSB, they were very limited when compared with those of digestion. The bran recombination process was better for the preparation of CSB than direct ground process.Significance and noveltyIn addition to sensory qualities, this study also investigated the effects of digestion on the release of antioxidant activity of CSB with different degrees of debranning. Since the total antioxidant activity only slightly decreased after debranning of 0‐16% degrees, intaking CSB with lower bran content may also have considerable healthy benefit.

AbstractBackgroundThough the incidence, characteristics, and pathogenesis of chemotherapy induced peripheral neuropathy (CIPN) by taxane based chemotherapy were extensively studied, diagnostic guidelines extent only recently.AimTo observationally investigate whether specific tests can be used to predict and monitor CIPN severity.MethodsFourteen female breast cancer patients receiving paclitaxel or docetaxel were evaluated using the McGill Pain Questionnaire (MPQ), National Cancer Institute Common Toxicity Criteria (NCI‐CTC) grading, clinical total neuropathy score (TNSc), quantitative sensory testing (QST) of pressure pain threshold (PPT), and numeric rating scale (NRS) scores and stocking and glove distribution testing (SGDT), at the start (T0), midst (T1), and end (T2) of their treatment and after 3 months (T3).ResultsAt T3, patients scored NCI‐CTC neuropathy grade 1 (14.3%), 2 (64.3%), and 3 (14.3%) respectively. Fifty percentage scored at least grade 1 at T0, with complaints not caused by CIPN. Pain, if present, was denominated “tingling” and “cold” in the MPQ. Median TNSc score increased from T0 (2.43) to T1 (4.71) to T2 (5.50) to T3 (5.57), as did pinprick and cold sensation disturbances in SGDT. PPT and associated NRS remained unchanged. TNSc and SGDT at T1 could not predict the NCI‐CTC grade at T3.ConclusionNCI‐CTC, TNSc, and stocking and glove distribution testing can be used in the early diagnosis and monitoring of CIPN, with false‐positive findings at baseline. Final NCI‐CTC grades could not be predicted.
Screening for diabetic retinopathy with fluorescein angiography in patients with type 1 diabetes from adolescence to adult life. A retrospective study of the past 30 years of clinical practice in a tertiary Belgian centre

Published: October 2021

AbstractBackgroundThe aim of the present study was to describe the prevalence and progression of DR diagnosed by fluorescein angiography (FA) in patients with type 1 diabetes (T1D) during a 30‐year follow‐up, and the relationship with glycated haemoglobin (HbA1c).Materials and methodsWe included 4325 FA reports representing 851 patients with T1D with a mean age at diagnosis of 10.4 years (range: 0.0–49.9) and followed between 1986 and 2015. Clinical characteristics of the population were collected from patients’ files. The HbA1c level was measured within a maximum period of ±1 year from the date of FA. Descriptive statistics were realized to study prevalence and progression of DR.ResultsAt diagnosis of incipient abnormalities, mean age was 22.8 years (range 13.7–46.9) and mean diabetes duration was 13 years (range: 4.3–29.6). Lesions requiring treatment were observed in 5.9% of the patients at a mean age of 32.4 years (range: 30.4–34.3) and a mean diabetes duration of 23.8 years (range: 19.4–28.1). On average, it took 12.9 years (range: 12.2–13.5) to progress from an incipient abnormality to a lesion requiring treatment. Mean HbA1c ± SD was 7.8 ± 1.5% over a period of 30 years.ConclusionsWhile it could have been expected to observe a higher prevalence of DR, our study described by far the lowest results of prevalence comparing to similar studies, probably due to a good average HbA1c over 30 years.
N‐myc downstream regulated family member 1 (NDRG1) is enriched in myelinating oligodendrocytes and impacts myelin degradation in response to demyelination

AbstractThe N‐myc downstream regulated gene family member 1 (NDRG1) is a gene whose mutation results in peripheral neuropathy with central manifestations. While most of previous studies characterized NDRG1 role in Schwann cells, the detection of central nervous system symptoms and the identification of NDRG1 as a gene silenced in the white matter of multiple sclerosis brains raise the question regarding its role in oligodendrocytes. Here, we show that NDRG1 is enriched in oligodendrocytes and myelin preparations, and we characterize its expression using a novel reporter mouse (TgNdrg1‐EGFP). We report NDRG1 expression during developmental myelination and during remyelination after cuprizone‐induced demyelination of the adult corpus callosum. The transcriptome of Ndrg1‐EGFP+ cells further supports the identification of late myelinating oligodendrocytes, characterized by expression of genes regulating lipid metabolism and bioenergetics. We also generate a lineage specific conditional knockout (Olig1cre/+;Ndrg1fl/fl) line to study its function. Null mice develop normally, and despite similar numbers of progenitor cells as wild type, they have fewer mature oligodendrocytes and lower levels of myelin proteins than controls, thereby suggesting NDRG1 as important for the maintenance of late myelinating oligodendrocytes. In addition, when control and Ndrg1 null mice are subject to cuprizone‐induced demyelination, we observe a higher degree of demyelination in the mutants. Together these data identify NDRG1 as an important molecule for adult myelinating oligodendrocytes, whose decreased levels in the normal appearing white matter of human MS brains may result in greater susceptibility of myelin to damage.
