Authors: Fathimah Fathimah
Published: September 2021

The implementation of online learning is a learning model carried out during the pandemic. The application of online learning certainly requires the readiness of various parties, both from the school, office holders, and the students. There are things that must be considered in online learning, including the quality of teacher resources, both in terms of content and methodology as well as in terms of the use of information technology. In addition, students are also less active in participating in this online learning, either due to an unstable internet network or in terms of providing limited internet quota. The purpose of writing this article is to learn and understand the problems in learning activities during the pandemic, namely distance learning through online media so that students can follow it actively and interestingly. Distance learning (PJJ) through online media during the COVID-19 pandemic has led to various responses and changes to the learning system that can affect the learning process and the level of development of students in responding to material.

Published: September 2021

Introduction: Multiple and diverse contributors of homicidal ideation and homicidal/assault victimization exist. Although multiple studies have been conducted to examine the homicidal victimization, there is dearth in the literature regarding homicidal ideation. Therefore, we undertook this study to investigate and compare perpetrators of homicide to victims of homicide or assault, based on race and ethnicity. Methods: We conducted a retrospective cross-sectional analysis of inpatient hospitalizations in the US from January 1, 2010 and December 31, 2017 using Nationwide Inpatient Sample data. We estimated the risk of homicidal ideation and homicidal/assault victims among various racial/ethnic groups using survey logistic regression models, while adjusting for patient demographic and hospitalization characteristics. R and RStudio were utilized to conduct all statistical analyses and Joinpoint Regression Program for conducting temporal trends analyses. Results: During the study duration 2010-2017, there were 358,687 (0.12%) hospitalizations related to homicidal ideation. In 2017, the rate of homicidal/assault victimization related hospitalizations were 0.20%. After adjusting for covariates, Non-Hispanic (NH)-Blacks had an increased likelihood (Odds Ratio (OR): 1.41, 95% Confidence Interval (CI): 1.17-1.69) to have homicidal ideations and to be victims of assault and homicide (OR: 2.38, 95% CI: 2.06-2.75) compared to NH-Whites. Conclusions and Implication for Translation: Our study shows that significant racial/ethnic disparities exist for homicidal ideation and being victims of homicide and assault in the US during the study period. Targeted mental and behavioral health intervention towards NH-Black community could help prevent them from becoming perpetrators and victims of homicide.

Published: September 2021

The Xiagou Formation is the main tight oil reservoir in Qingxi Sag of Jiuquan Basin. Given the poor physical properties and other factors restricting tight oil exploitation and production in this area, studies should focus on microscopic pore structure characteristics. In this study, a nano-CT scanner, a SEM, and an NMR were used to study the pore structure characteristics of a tight carbonate reservoir in Qingxi Sag, Jiuquan Basin. The Xiagou Formation reservoir mainly consists of gray argillaceous dolomite and dolomitic mudstone. The pore categories are mainly elliptic, irregular, intergranular, and intragranular and mostly filled with clay and carbonate cement. Pore space is small, the intergranular or organic pores are mostly separated, and pore-throat is weakly connected. The throats mostly develop with lamellar and tube bundle-like characteristics and with poor seepage ability. The pore-throats mostly span from nanometer to micrometer sizes, and pore diameters are mainly concentrated in the range of 0.01–0.1 and 1–10 μm. It is a unimodal pattern mainly composed of micropores, or a bimodal regular allocation dominated by micropores supplemented by macropores. The relationship between micropore (<0.1 μm) and macropore (>1 μm) content allocation and mean pore diameter strongly controls the permeability of reservoir rocks. When macropore content reaches more than 85%, or when pore content totals less than 3%, the permeability of a reservoir remarkably increases. At a higher ratio of the average finest throat sectional area and throat-pore of reservoir rock, the throat radius lies closer to the connecting pore radius, pore and throat connectivity improves, and reservoir seepage ability becomes stronger. Based on reservoir capacity and seepage ability, pore structures of the tight carbonate reservoirs in study area are classified into type I (small-pore–thin-throat), type II (thin-pore–thin-throat), and type III (microporous-microthroat) with rock permeability>0.1 mD, 0.05–0.1 mD, and <0.05 mD, respectively. The type I pore structure reservoir should be regarded as an indicator of tight oil “sweet spots” reservoir in the study area.

Published: September 2021

Objetivo. Analizar la gobernanza en el sistema de salud en México, en las políticas frente a la pandemia por Covid-19. Material y métodos. Estudio cualitativo, analítico, realizado entre junio y noviembre de 2020. Se analizaron 41 entrevistas semiestructuradas que se aplicaron a acto­res clave del sistema de salud y que se organizaron en el software ATLAS.ti 9. El análisis se adhirió a los principios teórico-metodológicos del Marco Analítico de Gobernanza. Resultados. El problema: la formulación de políticas fue centralizada; los actores: sólo los altos mandos participan en las decisiones; las normas: los valores sociales y el liderazgo determinan su nivel de responsabilidad; toma de decisio­nes: los altos mandos reconocieron poder para proponer modificaciones al Marco Normativo; los nodos: las políticas federales fueron adaptadas a nivel estatal de manera diferen­ciada. Conclusiones. La gobernanza centralizada, los niveles diferenciados de convocatoria de los actores, su poder de decisión, acuerdos, responsabilidad y liderazgo, definieron el alcance de la gobernanza y, a su vez, el nivel de respuesta ante la pandemia por Covid-19.

Published: September 2021

Um dos espaços mais prósperos para estudos etno-pedológico e ecológico é a utilização dos solos para atividades artesanais. Vários estados brasileiros registram uma grande produção de objetos em barro, porém essa cultura não tem recebido atenção apropriada. O objetivo da pesquisa é registrar e analisar o conhecimento das mulheres louceiras da comunidade Ligeiro de Baixo, Serra Branca, Paraíba, Brasil, sobre o uso do solo para fins artesanais, identificando as políticas públicas de apoio e incentivo, seu impacto para as louceiras e as dificuldades no processo da coleta, produção e comercialização. Os dados foram coletados por observação direta, entrevista semiestruturada e diálogo informal. Foram entrevistadas seis louceiras diretamente. Ainda que detenham o conhecimento dos mais experientes, a nova geração não demonstra interesse na continuidade da atividade sobretudo pela desvalorização cultural, político-social e econômica. Tornam-se urgentes gestões mais participativas e ações em educação e cultura para o despertamento da sociedade e a preservação desse conhecimento tradicional que traduz toda história de um povo.
Produção e caracterização de biofilmes de fécula de mandioca com extratos aquoso e alcoólico de própolis
Authors: Silva Cristieli Nunes da , Fukuoka Talita Moura , Manhani Maria Raquel
Published: September 2021

Os polímeros sintéticos são amplamente utilizados nas indústrias devido à variedade de aplicações que possuem e por apresentarem longa durabilidade. Contudo, a grande resistência desses materiais contribui diretamente para que demorem centenas de anos para serem degradados, o que tem causado inúmeros problemas ambientais. A partir desse cenário, muitas empresas que consumiam polímeros em grande quantidade, iniciaram uma busca por alternativas para tratamento desses resíduos ou por substitutos para os materiais que utilizavam, e nessa nova tendência, alguns produtos se destacaram, como por exemplo, os biopolímeros, produzidos a partir de matérias-primas de fontes renováveis, dentre as quais, destacam-se o amido de milho, de mandioca e de batata, polilactato e poliidroxialcanoato. Neste trabalho, biofilmes de fécula de mandioca foram preparados pela técnica de casting, utilizando-se glicerol como plastificante, e incorporados de extratos etanólico e aquoso de própolis (EGP e EAP, respectivamente) em três diferentes concentrações (1,2%, 1,5% e 1,8%), a fim de se determinar as propriedades físicas e mecânicas, investigar o tempo de sua biodegradabilidade, além de avaliar possível atividade antibacteriana destes filmes. A avaliação das características físicas e mecânicas demonstrou que os filmes produzidos apresentaram resultados satisfatórios em comparação aos parâmetros encontrados na literatura e em relação à amostra controle (sem extrato). Para algumas das análises, como por exemplo, a umidade e a resistência ao rasgo, pode-se notar que a variação no tipo dos extratos influenciou diretamente os valores obtidos nos ensaios e, consequentemente, o desempenho do material. Quanto à biodegradabilidade, foram alcançados resultados muito favoráveis, visto que após 45 dias, houve a degradação completa dos filmes enterrados em solo arenoso. A respeito da atividade antibacteriana, notou-se a capacidade que ambos os extratos tiveram em inibir as suspensões bacterianas de Escherichia coli e Staphylococcus aureus. Diante do exposto, percebe-se o potencial de utilização dos biofilmes desenvolvidos como alternativa ao uso dos polímeros sintéticos, contribuindo assim para diminuir os impactos negativos causados ao meio ambiente, como alternativa ao uso dos polímeros sintéticos, contribuindo assim para diminuir os impactos causados no meio ambiente.

Muonium-Antimuonium Conversion
Authors: Willmann Lorenz , Jungmann Klaus
Published: September 2021

The MACS experiment performed at PSI in the 1990s provided an yet
unchallenged upper bound on the probability for a spontaneous conversion
of the muonium atom, { M=}({\mu^+e^-})M=(μ+e−),
into its antiatom, antimuonium {\overline{{M}} = }({\mu^-e^+})M¯=(μ−e+).
It comprises the culmination of a series of measurements at various
accelerator laboratories worldwide. The experimental limits on the
process have provided input and steering for the further development of
a variety of theoretical models beyond the standard theory, in
particular for models which address lepton number violating processes
and matter-antimatter oscillations. Several models beyond the standard
theory could be strongly disfavored. There is interest in a new
measurement and improved sensitivity could be reached by exploiting the
time evolution of the conversion process, e.g., at intense pulsed
muonium sources.
The $\pi^0$ mass and the first experimental verification of Coulomb de-excitation in pionic hydrogen
Authors: Daum Manfred , Kettle Peter-R.
Published: September 2021

The most precise value for the \pi^0π0
mass was obtained from the measurement of the mass difference
m_{\pi^-}-m_{\pi^0} = 4.593\,64(48)mπ−−mπ0=4.59364(48),MeV/c^22
in the charge exchange reaction \pi^-π−p
\rightarrow \pi^0→π0n
at PSI. With the most precise charged pion mass value,
m_{\pi^+} = 139.570\,21(14)mπ+=139.57021(14),MeV/c^22
and the validity of the CPT theorem (m_{\pi^-} = m_{\pi^+}mπ−=mπ+),
a value m_{\pi^0} = 134.976\,57(50)mπ0=134.97657(50),MeV/c^22
is obtained. The measurements also revealed, for the first time,
evidence of an unexpectedly large contribution from Coulomb
de-excitation states during the pionic atom cascade.
Pionic hydrogen and deuterium
Authors: Gotta Detlev , Simons L. M.
Published: September 2021

The measurement of strong-interaction shift and
broadening in pionic hydrogen and deuterium yields pion-nucleon
scattering lengths as well as the threshold pion-production strength
on isoscalar NN pairs. Results from recent high-resolution
experiments at PSI using crystal spectrometers allow important
comparisons with the outcome of the modern low-energy description of
QCD within the framework of effective field theories.
Measurement of the transverse polarization of electrons emitted in neutron decay – nTRV experiment
Authors: Bodek Kazimierz , Kozela Adam
Published: September 2021

This paper recalls the main achievements of the nTRV experiment which
measured two components of the transverse polarization
(\sigma_{T_{1}}σT1,
\sigma_{T_{2}}σT2)
of electrons emitted in the \betaβ-decay
of polarized, free neutrons and deduced two correlation coefficients,
RR
and NN,
that are sensitive to physics beyond the Standard Model. The value of
time-reversal odd coefficient RR,
0.004\pm±0.012\pm±0.005,
significantly improved limits on the relative strength of imaginary
scalar coupling constant in the weak interaction. The value obtained for
the time-reversal even correlation coefficient
NN,
0.067\pm±0.011\pm±0.004,
agrees with the Standard Model expectation, providing an important
sensitivity test of the electron polarimeter. One of the conclusions of
this pioneering experiment was that the transverse electron polarization
in the neutron \betaβ-decay
is worth more systematic exploring by measurements of yet experimentally
not attempted correlation coefficients such as
HH,
LL,
SS,
UU
and VV.
This article presents a brief outlook on that questions.
The search for the neutron electric dipole moment at PSI
Authors: Pignol Guillaume , Schmidt-Wellenburg Philipp
Published: September 2021

The existence of a nonzero permanent electric dipole moment (EDM) of
the neutron would reveal a new source of CP violation and shed light on
the origin of the matter–antimatter asymmetry of the Universe. The
sensitivity of current experiments using stored ultracold neutrons (UCN)
probe new physics beyond the TeV scale. Using the UCN source at the Paul
Scherrer Institut, the nEDM collaboration has performed the most
sensitive measurement of the neutron EDM to date, still compatible with
zero (|d_n|<1.8\times 10^{-26} \, e {cm}|dn|<1.8×10−26ecm,
C.L.,90%). A new experiment designed to improve the sensitivity by an
order of magnitude, n2EDM, is currently under construction.
Indirect searches for dark matter with the nEDM spectrometer
Authors: Roccia Stephanie , Zsigmond Geza
Published: September 2021

The nEDM apparatus at PSI has been used to search for different dark
matter signatures utilizing its high sensitivity to shifts in the
neutron precession frequency and its well-controlled low magnetic field
at the \muμT
level. Such a shift could be interpreted as a consequence of a
short-range spin-dependent interaction that could possibly be mediated
by axions or axion-like particles, or as an axion-induced oscillating
electric dipole moment of the neutron. Another search, based on
so-called UCN disappearance measurements, targeted previously reported
signals of neutron to mirror-neutron oscillations. These dark matter
searches confirmed and improved previous results, as detailed in this
review.

The SARS-CoV-2 pandemic known as COVID 19 has placed an overwhelming burden on health systems and authorities to respond with effective and appropriate interventions, policies and message. , it is important for doctors working with the population to have adequate knowledge related to SARS-CoV-2 pandemic which should be of great help in dealing with the emerging situation. This survey was aimed to find out the level of knowledge related to SARS-Cov-2 among doctors, interns and medical undergraduate students with particular emphasis on Bihar. Objectives : to assess the basic knowledge among doctors, interns and undergraduate students that is needed for the prevention and treatment of the COVID19 disease and to find out any differences in their knowledge with associated factors. Methodology: A cross-sectional survey among doctors and undergraduate medical students was conducted during the first COVID-19 wave using a validated self-administered questionnaire of 14 items, sent to doctors via online platforms. The data was analyzed using SPSS v.20. Results : Good score was secured more by males and elder doctors as compared to females and younger ones. Doctors who thought they have good knowledge ,actually scored good. Conclusion: The knowledge related to COVID-19 in doctors of Bihar was found to be at par with other states of India. In general they appear to be motivated to upgrade their knowledge. However, the average knowledge among undergraduate medical students cautions for careful induction of them in COVID 19 workforce if needed.
La figura de Beatriz como idealización poética en la Comedia de Dante Alighieri
Authors: Vásquez Gómez Víctor Hugo , Benavides Guevara Cristian Alejandro
Published: September 2021

Este artículo tiene como objetivo examinar si la representación poética de la figura de Beatriz en la Comedia se corresponde con el sí mismo dantesco a la manera de una proyección, de una ensoñación idealizada. A partir de los estudios sobre el fenómeno de la ensoñación poética de Gastón Bachelard y los de C. G. Jung sobre los sueños y la naturaleza andrógina del alma humana (anima anima-animus), se hace una lectura en perspectiva crítico hermenéutica de la Comedia, considerando dos interrogantes principales: ¿cuál es el estatuto psíquico de la ensoñación dantesca? Y ¿cuál es la simbología que entraña el ideal femenino de Beatriz y que el mismo Dante –por no poseer– desea y proyecta poéticamente? Se argumenta que la Comedia puede entenderse como un elogio del sumo amor idealizado, interpretando que los valores expresados en las palabras y en el êthos de Beatriz no son más que la proyección del anima dantesca, es decir, que desde la teoría de la ensoñación poética de Bachelard, Beatriz se erige como una idealización del deseo de virtud del propio Dante.
Un concilio, dos papas, tres patriarcas: el último tardío intento ecuménico entre Oriente y Occidente
Authors: Echeverri Guzmán Alberto
Published: September 2021

El empeño ecuménico que acomuna hoy a las iglesias cristianas, impone una revisión de los propósitos que en esa línea se han impulsado a lo largo de los siglos que siguieron a la separación de las iglesias de Occidente y Oriente. El concilio de Basilea-Ferrara-Florencia-Roma, a mediados del siglo XV, constituye una piedra miliar de ese itinerario eclesial. Alentado por Roma y por Constantinopla, las capitales religiosas y políticas de los imperios de Occidente y Oriente que sobrevivían entonces, considerado hoy ecuménico por la primera mas no por la segunda, forma parte de esas tentativas. Incluido como un logro, si bien de corto alcance, su efectivo influjo respecto de la unión de las dos comunidades eclesiales se pierde en los vericuetos de la historia. Objetivo del artículo será desentrañar su significación actual para la causa ecuménica cristiana mediante un método histórico hermenéutico que somete a examen los intereses políticos y religiosos en él entrecruzados.

Ukraine leads Europe in the number of rabies cases reported in both wild and domestic animals. Endemic rabies in Ukraine poses a threat of rabies spreading into non-endemic neighbouring countries, including Poland, Slovak Republic, Hungary and Romania. This study is the first to collate and analyze rabies cases at the national level in Ukraine. Spatial and temporal analysis was performed to identify space-time clusters of rabies cases using nationally collated rabies surveillance data from 2012-2018. In the study period, 10,717 rabies cases were confirmed, with the majority in domestic carnivores (49.5%; cats: 28.5%; dogs: 21.1%) and the other primarily in foxes (34.0%). Rabies epidemic curves identified peak rabies incidence from October to December for foxes and from October to March for domestic carnivores. The kernel density of rabies for all species indicates a permanently high density in southwest Ukraine (Zakarpattia and Vinnytsia oblasts) and lower in northeast Ukraine (Poltava oblast). The highest density of rabies cases in foxes occurred in oblasts bordering European countries, while rabid domestic carnivores were concentrated near the border with the Russian Federation. The analysis identified 10 statistically significant clusters in foxes and 3 in domestic carnivores, mostly in the same high kernel density locations. Early clusters of foxes were recorded on January 3, 2012 in western Ukraine (ratio, 2.21), and early clusters of domestic carnivores on January 30, 2012 in western Ukraine as well (ratio, 6.39). These findings provide insight into the temporal patterns and distribution of rabies case clusters in wildlife and domestic carnivores in Ukraine. Our study provides policymakers with the first statistically valuable data on the hotspot regions and timing of rabies outbreaks. The analysis may contribute to improved rabies prevention and surveillance strategies by identifying regions for targeted prevention measures so that national programmes for the prevention, surveillance and control of rabies in Ukraine are executed more effectively.
The Theoretical Proposition to Promote and Motivate Prison Labour in Ghana
Authors: Brobbey Priscilla
Published: September 2021

The ultimate purpose of the prison industry over the years was for the incarceration of criminals to serve their custodial sentence, which was later fused with rehabilitation programs to reform criminals to become better citizens after being released from custodial sentences. However, the outcome of the reformation of convicts after released from the prison has been a sad story than expected success cases. Hence, the theoretical proposition of the paper with respect to the prison industry of Ghana is to resolve recidivism, promote inmates’ skill upgrade and labour reformation programs to become socio-economic beneficial during and after a custodial sentence.

Authors: Wambaka Kosea
Published: September 2021

The banking landscape in Uganda is such that there is a section of commercial banks that has consistently posted impressive performance figures, particularly over the last five years, while the performance of the others leaves a lot to be desired. This study’s purpose was to examine the effect of differentiation strategy on the financial performance of commercial banks in Uganda. The study employed a cross-sectional design characterized by a quantitative approach. The target population in this study constituted 210 Senior Managers and Chief Executives of 10 selected commercial banks in Uganda that have been rated as the best performing commercial banks in the five years (2015-2019). A sample of 144 individuals was calculated for this study using Yamane’s (1967) formula, and the probability sampling technique of stratified proportionate random sampling was used in selecting Senior Managers of the selected commercial banks, and these were surveyed using a structured self-completion questionnaire. Quantitative data were analyzed descriptively using statistics such as frequencies, percentages, means, and standard deviations; and inferentially using partial least squares structural equation modelling (PLS-SEM). The findings showed a positive and statistically significant relationship between product differentiation strategy and financial performance in terms of ROI (β = 0.5841, ρ<0.05). The study concluded that product differentiation strategy is an important factor in the financial performance of commercial banks in Uganda particularly in terms of ROI.
Single Women Involved in Entrepreneurship Negatively Affected by Gender and Marital Status as Entrepreneurs
Authors: Chomba Brown
Published: September 2021

Issues to do with gender imbalances and inequality of women in general and single women in particular in the political arena and entrepreneurship are nowadays a burning issue in all the countries worldwide. This is a major aspect of modern democratic governance such that low levels of female participation in politics are a major concern worldwide. The steps were taken by the United Nations Convention on stopping all forms of Discrimination against Women (CEDAW) and other international organizations have laid the concrete basis for the emergence of women’s participation in politics and entrepreneurship. In Lusaka, Zambia, women’s political participation is not proportional to the 50% of the country’s population which women represent, thereby not translating into equal representation in political leadership positions. The study employed questionnaires to collect data. The findings demonstrate that there exists a significant gender gap in the political participation of women in all the wards in the Lusaka district and that factors affecting their effective participation were social, economic, political, cultural, and religious-based. The study, therefore, recommended the change of perception of the people, equal representation in governance, support from everyone, and also stopping of discriminatory practices to ensure the equal and full participation of women.

O presente trabalho versa sobre tema atual, qual seja, a (im)possibilidade da aplicação da reserva do possívelante a judicialização da saúde. Por meio de exploração bibliográfica e jurisprudencial, conseguiu-se identificar osparâmetros que o Poder Judiciário tem adotado para conceder tutelas liminares de urgência no âmbito do direitoà saúde. Tais balizas podem ser resumidas como: possibilidade de grave lesão à ordem, à saúde e à economia públicas;e possibilidade do fornecimento de medicamento de alto custo inviabilizar o adequado funcionamento doSistema Público de Saúde, bem como prejudicar o andamento dos serviços de saúde básica em relação ao restanteda população, além da concessão dessas tutelas liminares de urgência configurar indevida interferência do PoderJudiciário na esfera de atribuições do Poder Executivo. Concluiu-se, então, que é necessário que haja a observânciado princípio da proporcionalidade com a finalidade de respeitar o sistema de checks and balances necessário entreos três Poderes.
