A MUDANÇA DO HABITUS DAS INSTITUIÇÕES FEDERAIS DE ENSINO SUPERIOR ATRAVÉS DE POLÍTICAS PÚBLICAS INCLUSIVAS: A NECESSIDADE DE IR MAIS ALÉM
Authors: Tavares Neto José Querino , Cruvinel Pedro Henrique Moreira
Published: April 2021

O artigo analisa como a formação da sociedade brasileira influenciou a constituição de uma das sociedades mais desiguais do mundo. As instituições de ensino superior, sobretudo as públicas, foram instituídas sob o signo dessa desigualdade, funcionando como instituições legitimadoras. A adoção de políticas públicas inclusivas, por sua vez, conseguiu inserir o jovem das classes menos favorecidas no ambiente universitário. Entretanto, esse é apenas o primeiro passo. É necessário ir além, ou seja, criar políticas públicas para que o egresso das universidades por meio de políticas públicas tenha a mesma oportunidade que os demais. O objetivo do presente artigo, portanto, é analisar como o estamento moldou a sociedade e universidade brasileira, para depois revelar a mudança do habitus no ensino superior e, por fim, apontar alternativas para o fenômeno inflacionário do diploma universitário.
LUCES Y SOMBRAS EN LA COMPRAVENTA DE VIVIENDA EN CONSTRUCCIÓN EN ESPAÑA. PARTICULARIDADES Y EFECTIVIDAD DE LOS PACTOS PREVIOS
Authors: Alonso Silvia Durán
Published: April 2021

La compraventa de vivienda “sobre plano” es un contrato de muy frecuente aplicación práctica en España, que lleva consigo una problemática derivada de sus especiales caracteres, como son el hecho de ser un contrato sobre un bien que aún no existe como tal, y que además está reconocido como bien de primera necesidad. A ello hay que añadir el carácter de profesional del ramo que, normalmente, tiene una de las partes del contrato (el vendedor-promotor), y la falta de regulación unitaria del mismo. Todo ello ha dado lugar a una extensa jurisprudencia sobre los distintos problemas que plantea este negocio jurídico. En el presente artículo, se hace un acercamiento inicial a esta figura, y se analiza la efectividad de los pactos previos que, muy habitualmente, acompañan a este tipo de contratos.
TeleGate: Multi-user Semi-teleportation for Remote Collaboration in Mixed Reality 360-Videos
Authors:   , Kim Hye Jin
Published: April 2021

Telepresence systems enable people to feel present in a remote space while their bodies remain in their local space. To enhance telepresence, the remote environment needs to be captured and visualised in an immersive way. For instance, 360-degree videos (360-videos) shown on head-mounted displays (HMDs) provide high fidelity telepresence in a remote place. Mixed reality (MR) in 360-videos enables interactions with virtual objects blended in the captured remote environment while it allows telepresence only for a single user wearing HMD. For this reason, it has limitations when multiple users want to experience telepresence together and naturally collaborate within a teleported space.

This thesis presents TeleGate, a novel multi-user teleportation platform for remote collaboration in a MR space. TeleGate provides "semi-teleportation" into the MR space using large-scale displays, acting as a bridge between the local physical communication space and the remote collaboration space created by MR with captured 360-videos. Our proposed platform enables multi-user semi-teleportation to perform collaborative tasks in the remote MR collaboration (MRC) space while allowing for natural communication between collaborators in the same local physical space.

We implemented a working prototype of TeleGate and then conducted a user study to evaluate our concept of semi-teleportation. We measured the spatial presence, social presence while participants performed remote collaborative tasks in the MRC space. Additionally, we also explored the different control mechanisms within the platform in the remote MR collaboration scenario.

In conclusion, TeleGate enabled multiple co-located users to semi-teleport together using large-scale displays for remote collaboration in MR 360-videos.

Nigerian Rural Communities and Media Marginalization on COVID-19: Perspectives on Participatory Video
Authors: Omoera, Ph.D. Osakue Stevenson , Onyemuchara Casmir E , Okwuowulu Charles
Published: April 2021

This article examined the impact of participatory video (PV) technique in (re)educating rural dwellers on Corona virus (COVID-19) at Iva-Valley Forestry Hill Camp 1, Southeast Nigeria, with a view to generating data that could be tested or extrapolated elsewhere. It used historical-analytic, key informant interview (KII) and direct observation methods to argue that the COVID-19 pandemic/period has exposed weaknesses immanent in human institutions globally. One of such exposed interstitial gaps is the seeming weak media-link in the rural areas. This situation results from lack of electricity, non-access to reliable locally-generated news by resident community members and the lack of know-how to use mobile phones to generate media contents. Rural dwellers constitute 49.66 percent of the total Nigerian population (National Population Commission [NPC], 2018), yet media focus in Nigeria is mostly urban-driven. Having interacted and co-created a video script in Igbo with the community members through PV to determine the level of (mis)information that has permeated the community and (re)educated the rural dwellers on Corona virus and strategies to prevent its spread, the study canvassed the use of indigenous languages, diversification of media and PV techniques in the dissemination of credible information on COVID-19 in Nigeria, particularly at the grassroots

Published: April 2021

As relações entre o ENOS e a precipitação na Amazônia são analisadas num contexto espacial e temporal. Para isso, foram utilizados os dados mensais de precipitação de 238 estações distribuídas nos estados do Amazonas, Amapá, Pará e Maranhão, no período de 1920 a 2011. A identificação dos eventos de El Niño e La Niña foi feita através da análise dos campos de anomalias de precipita-ção, e foi aplicada a transformada em Ondeleta Morlet para a caracterização de todas as oscilações presentes no sinal da precipitação para o período estudado. Os resultados mostram que a distribuição espacial das anomalias positivas e negativas é bastante heterogênea, devido às interações das diferentes dimensões de tempo e escala do fenômeno ENOS e das condições de superfície da Ama-zônia. A diferença entre os eventos de El-Niño de 1982/83 e 1997/98 está relacionado à maior atua-ção em área com anomalias negativas, causando uma redução na precipitação no leste da Amazônia. Observou-se que os eventos de ENOS foram modulados por oscilações de precipitações de múlti-plas escala de tempo, tais como: decadal, interdecadal, anual e intrasazonal. Já as oscilações intrasa-zonais estiveram relacionas apenas ao evento de La-Niña 1984/85.  A B S T R A C T This study examined the relationship between ENSO and precipitation in the Amazon in a spatial and temporal. For this, we used the monthly data of precipitation of 238 stations distributed in the states of Amazonas, Amapá, Pará and Maranhão (period 1970 – 2011). For the analysis of data were made calculations of anomalies of precipitation, to identify the events of El Niño and La Niña, and application of the Wavelet Transform into Morlet to the characterization of oscillations in the sign of precipitation. The results show that the spatial distribution of positive and negative anomalies is quite heterogeneous, because the interactions of the different dimensions of time and scale of the ENSO phenomena and the surface condition of the Amazon. The difference between the events of El Niño of 1982/83 and 1997/98, be related to increased activity in an area with negative anomalies, causing a decrease in precipitation in eastern Amazonia. It was observed that the events of ENSO have been modulated by oscillations of precipitation of multiple time scale, such as decadal, interdecadal, annual and intraseasonal. It was noted also that the intraseasonal oscillations were related only to the La-Niña event in 1984/85. Keywords: Wavelets Morlet, Water Resources, extreme events.

Published: April 2021

Climate changes may generate significant impacts in the hydrological cycle. It is important to recognize modifications in green water (water stored in soil followed by the consumption of the vegetation) and blue water (water that flows into rivers, lakes, wetlands and shallow aquifers) availability in consequence of climate change modifications. The mathematical modelling is used to simulate the effect of climate change scenarios in hydrological processes in watersheds. This study aimed to evaluate the impacts of climate change in blue and green water in Apucaraninha River Watershed, Southern Brazil, considering the climate scenarios A2 and B2, pessimistic and optimistic, respectively, about greenhouse gases emissions developed by IPCC. SWAT was calibrated and validated using daily streamflow from 1987 to 2012. Climate scenarios A2 and B2 were used to simulate the hydrological conditions for the period 2071-2100. The model presented satisfactory fit compared to the observed data allowing the simulation of the current hydrological conditions, therefore permitting the simulation of future climate change impacts on green and blue water. We found that despite the increase in potential evapotranspiration of 19% and 12% for A2 and B2 scenario respectively, caused by the increase in temperature, the reduction in rainfall amount induced to a reduction in actual evapotranspiration, which correspond to green water, and a reduction of 1% for A2 scenario and 14% for B2 scenario in blue water availability.

Published: April 2021

The advent of antibiotic resistance and the growth of new strains of bacteria are of great concern to the world health sectors. Effective treatment of the infections caused by these human pathogens call for designing and development of new drugs with better efficiency. This study aimed at investigating the antibacterial activity of Moringa oleifera seed extract against some bacteria strains. The phytochemical and antibacterial activities of Moringa oleifera seed extract against both Gram-positive and Gram-negative bacteria were conducted using standard methods. The phytochemical analysis of the studied seed extract revealed the presence of alkaloids, tannins, saponins, phenols and flavonoids as secondary metabolites. The obtained result from the antibacterial study indicated that the extract exhibited high inhibition zones against all bacteria strain studied. Also, four molecular compounds from Moringa oleifera seed were selected based on their percentage yield and were optimized using density functional theory and they were used against five bacterial cell lines. It was observed that kaempferol and quercetin inhibited Escherichia coli. Kaempferol inhibited Klebsiella pneumonia, Pseudomonas aeruginosa, and Streptococcus pneumonia while Quercetin showed highest inhibition against Staphylococcus aureus when compared with other compounds. This showed the effectiveness of Moringa oleifera seed in eradicating some infections caused by bacteria.

Published: April 2021

Secondary Hyperparathyroidism (sHPT) is a secondary effect of diseases outside theparathyroid glands which causes a decrease in calcium levels and an increase in the work of theparathyroid glands in increasing the body's calcium levels. This literature review aimed todetermine the effect of CaCO 3 contained in eggshells on the PTH profile in secondaryhyperparathyroidism and its side effects. The journals used in the writing of this article weresourced from PubMed, Embase, Medline, and Google Scholar using keywords and the PRISMA method. Based on the results of the study, it was known that the shell of a domestic chicken egg(Gallus domesticus) contains approximately 97% CaCO 3 . The potential of eggshell powdercontaining CaCO 3 was to reduce parathyroid hormone (PTH) in sHPT and increased calciumlevels by binding mechanisms and forming insoluble complexes with phosphate in the intestine,but the effect of other eggshell substances was still limited. Based on this, it can be concludedthat eggshell powder could play a role in lowering the PTH hormone in secondaryhyperparathyroidism and increasing calcium levels in the blood with minimal side effects.However, further clinical trials are still needed to evaluate the clinical effects.

Keywords: Secondary hyperparathyroidism; Eggshell; Calcium carbonate (CaCO?), Parathyroidhormone

Kawasaki Disease is a spectrum of idiopathic, self-limited fever disease affecting childrenunder 5 years old. This disorder can be challenging to be diagnosed by a pediatrician since thereis no specific diagnostic laboratory test. One atypical Kawasaki Disease case presented withgastrointestinal symptoms, a two-year-old girl was hospitalized with fever, accompanied by non-hemorrhagic diarrhea three days before admission. Physical examination revealed unilateralcervical lymph enlargement and mild-moderate dehydration. Initial laboratory examinationresult showed thrombocytosis, leukocytosis (shift to the left), and normal routine fecal analysis.The patient was initially diagnosed with acute diarrhea with mild-moderate dehydration. She wastreated with a rehydration regimen and antibiotic, but her fever persisted. On the third day ofhospitalization, she fulfilled 3 of the classic Kawasaki Disease criteria (conjunctivitis, crackedlips with strawberry tongue, and lymphadenopathy). Further blood work resulted in increased C-reactive protein 43.35 mg/L and ESR 72 mm/hour, while chest X-ray and electrocardiographwere within normal limit. This patient was proceed to Hasan Sadikin General Hospital for furtherexamination and therapy. Atypical Kawasaki Disease can be a puzzling diagnosis due to itsuncommon presentations. Clinicians should importantly keep it in mind as a differential diagnosisin patients with prolonged fever.

Despite sufficient research studies in the field of drug abuse, drug relapse remains one of the salient aspects that has received less attention among research experts. This study thus investigated the prevalence of drug relapse among clients in NDLEA (National Drug Law Enforcement Agency) rehabilitation centres in North Central, Nigeria. A descriptive survey design was adopted for this study. Censors sampling method, that is, only the available clients or respondents (during the conduct of the study) at the rehabilitation centres in the North Central region participated in the study. A researcher-designed questionnaire on "Prevalence of Drug Relapse" was used to collect the relevant data. The instrument had a reliability co-efficient of 0.69 using the test re-test method. All hypotheses were tested using t-test and Analysis of Variance (ANOVA) statistics at a 0.05 level of significance. The main findings of the study revealed that drug relapse is moderately prevalent among clients in NDLEA rehabilitation centres in North Central, Nigeria. In view of this, it was recommended that NDLEA and other stakeholders should intensify efforts in identifying more addicted individuals so that they can go through the rehabilitation process and adjust effectively to their environment and avoid returning to drug/substance use after treatment.
C. G. Jung’s Thoughts on the Concepts of Leader and Leadership
Authors: Corlett John G. , Chisholm Laura F.
Published: April 2021

A review of the written record suggests that C. G. Jung had relatively little to say about leadership. It also appears that the scattered comments he did make on the topic have garnered him little credit. Sensing, however, under-acknowledged value in Jung’s offerings, the authors of the present study curate the various pieces of this material and comment on the relevance of Jung’s thoughts to the field of leadership studies. The authors suggest caution in interpreting his ideas, given the differences between social norms prevailing in Jung’s time and those current today, and recommend avenues for further application of Jung’s ideas on leadership.

The use of Information Technology (IT) has made our live comfortable at present however, it has also generated certain health concerns. The disproportionate exercise of IT, with indication to accessible literature, has been consistently interrelated with psychopathological indications counting the problems of aggression as well. Although this issue was not much focused in Pakistan, this study was planned to determine the connection among the expenditure of IT and aggression in Pakistani youth. The query incorporated 200 conveniently chosen Pakistani youth between 16 to 24 years of age from 4 cities. The Aggression Scale of Buss & Perry was used along with a demographic information questionnaire. The study was hypothesized that among Pakistani youth elevated utilization of IT would be positively correlated with higher levels of aggression. It was significantly proved by the results that elevated utilization of IT is positively and significantly correlated with aggression.

Проведен сравнительный анализ эффективности влияния комбинированной терапии с метилэтилперидинолом гидрохлоридом и мелатонином на уровень гликемии и суточной протеинурии, активность аконитатгидратазы, содержание диеновых конъюгатов, уровень белков теплового шока 70 и состояние липидного обмена у больных диабетической нефропатией. Комбинированная терапия с мелатонином, по сравнению со стандартным лечением, приводила к более значимому снижению уровня гликемии (на 36 %, p = 0,019) и протеинурии (на 63 %, p = 0,01), способствовала повышению уровня липопротеидов высокой плотности на 20 % (p = 0,003), а также, наряду с лечением с метилэтилперидинолом гидрохлоридом, снижала концентрацию триглицеридов на 50 % (p < 0,001) в сыворотке крови больных сахарным диабетом 2 типа, осложнённого диабетической нефропатией. Добавление к стандартной терапии метилэтилперидинола гидрохлорида оказывало более значимый эффект в отношении активности аконитатгидратазы, увеличивающейся на 53 % (p < 0,001), а комбинированное лечение с мелатонином более существенно снижало концентрацию диеновых конъюгатов (на 51 %, p = 0,001) в сыворотке крови больных. На большинство клинико-биохимических показателей развития диабетической нефропатии, а также параметры липидного и окислительного статуса, наиболее значимое воздействие оказывало комбинированное лечение с мелатонином, что может быть связано с реализацией им антиоксидантной и регуляторной биологической активности.

Исследовано влияние 3-[(е)-3-(3,5-дитрет-бутил-4-гидроксифенил)-3-оксопроп-1-енил]-6-метокси-хромен-4-она в дозах 25, 50, 100, 200 и 400 мг/кг на активность антиоксидантных ферментов (супероксиддисмутазы, каталазы и глутатионпероксидазы), концентрацию продуктов перекисного окисления липидов (ТБК-активные продукты и диеновые конъюгаты) и содержание митохондриального пероксида водорода в головном мозге крыс линии Вистар с фокальной ишемией. Соединение в дозе 50 мг/кг (внутрь, 1 раз в сутки на протяжении 3 дней после моделирования ишемии) повышало активность ферментов эндогенной антиоксидантной защиты в среднем в 2,3 раза (p ≤ 0,05), снижало концентрацию продуктов перекисного окисления липидов в сопоставимой с препаратом сравнения (этилметилгидроксипиридина сукцинат) степени (в среднем в 2 раза, p ≤ 0,05), превосходя при этом последний по степени влияния на уровень митохондриальной перекиси водорода на 28,9 % (p ≤ 0,05). В дозах 25 и 100 мг/кг исследуемое соединение также способствовало восстановлению антиокислительного статуса клеток, тогда как в дозах 200 и 400 мг/кг значимых изменений про/антиоксидантного состояния в головном мозге крыс отмечено не было.
Effects of Intake Valve Lift Form Modulation on Exhaust Temperature and Fuel Economy of a Low-loaded Automotive Diesel Engine
Authors: BAŞARAN Hasan Üstün
Published: April 2021

Exhaust after-treatment (EAT) systems on automotive vehicles cannot perform effectively at low loads due to low exhaust temperatures (Texhaust < 250oC). Con-ventional late intake valve closure (LIVC) technique - a proven method to im-prove diesel exhaust temperatures - generally requires the modulation of the whole valve lift profile. However, an alternative method - boot-shaped LIVC - only needs partial lift form modulation and can rise exhaust temperatures signif-icantly. Therefore, this study attempts to demonstrate that boot-shaped LIVC can be an alternative solution to improve exhaust temperatures above 250oC at low-loaded operations of automotive vehicles.A 1-D engine simulation program is used to model the diesel engine system operating at 1200 RPM engine speed and at 2.5 bar brake mean effective pres-sure (BMEP) engine load. Boot-shaped LIVC is achieved via keeping the valve lift constant (at 4.0 mm) for a while during closure and then closing it at different closure angles. The method results in up to 55oC exhaust temperature rise through reduced in-cylinder airflow and thus, is adequate to keep EAT system above 250oC at low loads. The longer the boot is kept during closure, the lower the air-to-fuel ratio is reduced and the higher the exhaust temperature flows at turbine exit. Similar to conventional LIVC, boot-shaped LIVC improves fuel con-sumption as pumping losses are decreased in the system. Despite aforementioned improvements, EAT warm-up is affected negatively due to the significant drop-off on exhaust mass flow rates. The need to modify only some parts of the lift profile is a technical advantage and can reduce production costs.

Bringing ICT into the Classroom: Perceptions from Tourism Students on Technology-Enhanced Learning
Authors:   Prince of Songkla University, Thailand, Fuchs Kevin
Published: April 2021

The advancement of Information and Communication Technology (ICT) can be seen as a blessing in disguise. On one hand, digital information is readily available nowadays, which in turn makes the hardwiring of knowledge less significant and shifts the focus towards competency development. In a digitalized world where information is easily accessible, it is argued that students in higher education need to develop more sensible soft skills that allow them to systematically and critically analyze information. Whilst knowledge can be acquired in a relatively short period, competency development requires more active repetition and patience. Thus, applying relevant and supportive teaching methods is seen as essential. Quantitative data was collected from the participants (n=107) and examined through descriptive analysis. The results of the research revealed that students in higher education generally had a positive perception of technology-enhanced learning (TEL) and considered themselves proficient with the usage of ICT in the classroom. Based on the empirical findings from this paper, a qualitative study was recommended to identify how ICT can be more effectively integrated into the traditional classroom.
Untested Admissions: Examining Changes in Application Behaviors and Student Demographics Under Test-Optional Policies
Authors: Bennett Christopher T.
Published: April 2021

This study examines a diverse set of nearly 100 private institutions that adopted test-optional undergraduate admissions policies between 2005–2006 and 2015–2016. Using comparative interrupted time series analysis and difference-in-differences with matching, I find that test-optional policies were associated with a 3% to 4% increase in Pell Grant recipients, a 10% to 12% increase in first-time students from underrepresented racial/ethnic backgrounds, and a 6% to 8% increase in first-time enrollment of women. Overall, I do not detect clear evidence of changes in application volume or yield rate. Subgroup analyses suggest that these patterns were generally similar for both the more selective and the less selective institutions examined. These findings provide evidence regarding the potential—and the limitations—of using test-optional policies to improve equity in admissions.

Published: April 2021

The purpose of this paper is to examine how corporate governance instruments impact firm value in the context of Cambodian banks. This paper considers foreign and domestic-owned banks in Cambodia. This study opts for a balanced sample of foreign and domestic owned banks for the period 2014-2018. Panel data regression is adopted for estimation of main results. The suitable model, i.e. fixed and random effect model is selected using the Hausman specification test where the result shows that the random effect model using generalized least square (GLS) regression is more suitable for the analysis. The findings show that Cambodian banks are having a substantially higher percentage of NEDs on their board, high implementation of governance procedures on board committees where on average the banks are having more than the required two board committees (audit and risk committees) as required by the Prakas on the governance of banks by National Bank of Cambodia. The average board size is around 8 members of which at least 3 members are having a postgraduate degree or a professional qualification. Policymakers need to improve on their supervisory function as the majority of the domestic and some foreign banks do not disclose their annual reports on their company website as required by the Prakas on Corporate Governance of Banks operating in Cambodia. Moreover, amendments should be made to the current corporate governance code for financial institutions as there are no explanatory notes that guide companies and therefore, the current guideline is open to individual and subjective interpretation.
