Foodborne Outbreak Investigation in Al-Ahsa, Saudi Arabia, 2021: A Retrospective Cohort Study (Preprint)
Authors: Alahmad Abdulmohsen , Kamel Shady Abdulrahman
Published: January 2022

BACKGROUND

On September 10, 2021, Al-Ahsa General Health Directorate reported an unexpected number of patients had presented with gastrointestinal symptoms. All the patients gave a history of sharing a common meal as they ate dinner that was served at the mother’s house in a family gathering on September 9, 2021, at 9 PM in Al-Ahsa.

OBJECTIVE

This study aims to confirm the existence of the outbreak, confirm the diagnosis, define and identify the cases, identify the source of the outbreak, determine the causative agent or organism if possible and its mode of transmission, and recommend preventive measures to be applied to prevent similar outbreaks in the future.

METHODS

A retrospective cohort design was used in this outbreak investigation to identify its source. Cases were defined as any person who ate dinner at the family gathering on September 9, 2021, and developed any or a combination of the following symptoms: diarrhea, vomiting, fever, or abdominal pain within 26 hours of food consumption. We collected information on demographics, symptoms, and food history using a semistructured questionnaire. We reviewed hospital records for symptoms and vital signs. We reviewed available laboratory results for cases, and we conducted an active case search to identify more cases. The data obtained was analyzed using SPSS version 21.0 (IBM Corp).

RESULTS

A total of 20 (74%) were defined as cases and 7 (26%) as noncases. Of 20 cases, 16 (80%) were females and 4 (20%) were males. The ages ranged between 2-70 years. Among cases, 59.3% had vomiting, 59.3% had a fever, 48.1% developed diarrhea, and 25% had abdominal pain. The incubation period ranged from 10 to 26 hours, with a mean of 17.8 hours. The risk ratios (relative risks) and P values were calculated for each food item to assess the association between consumption of individual food items and subsequent illness. Among 8 food items consumed, red pasta with chicken (relative risk 37.3, 95% CI 3.2-424.6) and beef pizza (relative risk 6.5, 95% CI 1.74-42.2) were significantly associated with illness.

CONCLUSIONS

According to the epidemiological investigation, symptoms, incubation period, and laboratory results, there might be some differential diagnosis, but we were unable to more definitively identify the source of the outbreak. We recommend more education to the households about food safety.

Cuauhnáhuac y Huaxtepec: tlalhuicas y xochimilcas en el Morelos prehispánico
Authors:   Escuela Nacional de Antropología e Historia, Maldonado Jiménez Druzo
Published: January 2022

Este libro combina la investigación histórica y antropológica en un enfoque que algunos estudiosos prefieren llamar etnohistoria. De acuerdo con este enfoque, Druzo Maldonado reconstruye la historia y la organización socioeconómica y política de una región específica del actual estado de Morelos: Cuauhnáhuac y Huaxtepec, que en el momento de la Conquista española formaban dos provincias tributarias del Imperio mexica. La región da en este caso el marco de análisis tanto en términos político-territoriales, económicos como históricos. Las fuentes usadas son las crónicas tradicionales disponibles del siglo XVI (cronistas españoles, indígenas y autores anónimos), códices, documentación de archivo proveniente de la administración colonial, así como la bibliografía moderna sobre la región.
Role of Forest Management in Environmental Studies with Reference to the Maintaining of Conservation Values
Authors: Shekhar Amritanshu
Published: January 2022

Abstract: A forest is a type of ecosystem in which there is high density of trees occupying a relatively large area of land. An ecosystem is an ecological unit consisting of a biotic community together with it’s a biotic environment. In the case of forest, tress dominant the biotic landscape, although there are also other plants and animals. There are many types of forest, such as tropical, evergreen, deciduous and dry forest based on the climatic condition and types of trees present. Forests provide innumerable values to people, provide aspects that address both physical needs as well as the internal nature of people. Forest help cleanse the air by intercepting airborne particles, reducing heat, and absorbing such pollutants as carbon monoxide, sulfur dioxide and nitrogen dioxide. Trees remove this air pollution by lowering air temperature, through respiration, and by retaining particulates. Erosion control has always started with tree and grass planting projects. Tree roots bind the soil and their leaves break the force of wind and rain on soil. Trees fight soil erosion, conserve rainwater and reduce water runoff and sediment deposit after storms. Herbs, shrubs and trees in the forests hold the topmost layer firmly by their roots. This does not allow natural forces like wind and water to carry away the topmost fertile layer of the soil easily. Hence, Forests prevent soil erosion. With forest conservation, animal species, insects and all the biodiversity of natural areas is protected. It is noteworthy that these beings and the local vegetation exert influence on conservation beyond deforestation and the regional climate, even interfering with the health of the local community.

“Como sin querer la cosa”. Insinuaciones e indeterminación en los encuentros entre esmeralderos y esmeraldas en Colombia
Authors: Caraballo Acuña Vladimir
Published: January 2022

En el contexto de la formalización de la minería en Colombia, mineros artesanales, comerciantes y talladores de esmeraldas suelen enfatizar la indeterminación en sus encuentros con ellas y con sus cualidades. En lugar de acechar para extraer, de planear para tallar o de estandarizar para vender, en general privilegian la impredecibilidad de los encuentros y la espectralidad de las piedras. Por ello, lo que hacen es diseñar insinuaciones específicas de las cuales los encuentros interruptivos pueden surgir de manera indeterminada. En sus palabras, hay que buscar, tallar y vender esmeraldas “como sin querer la cosa”. En este artículo propongo entender estas insinuaciones como prácticas lingüísticas y no lingüísticas que los esmeralderos usan para encontrarse con las esmeraldas y para crear la indeterminación como una teoría de su mundo que interrumpe el pensamiento económicopolítico de la formalización. Propondré que “como sin querer la cosa” nos da, como lo hace una guaca, la posibilidad de un pensamiento indeterminado erigido desde interrupciones y sorpresas. A este pensamiento, cuya naturaleza intento emular en la estructura misma del artículo, lo llamaré pensamiento esmeralda.
¿Qué es un campesino? ¿Qué son los campesinados? Un breve documento sobre cuestiones de definición
Authors: Edelman Marc
Published: January 2022

En muchos (aunque no todos) los instrumentos internacionales de derechos humanos, el artículo 1.º se utiliza para definir a los titulares de derechos. Las precisiones normativas de este tipo pueden ser controversiales —por ejemplo, en debates sobre quién es un “niño” en el periodo previo a la Convención sobre los Derechos del Niño—, pero también puede serlo su ausencia (como ocurrió con laDeclaración sobre los Derechos de los Pueblos Indígenas). La pregunta de cómo definir campesino y campesinado tiene una historia larga, complicada y polémica. Las definiciones de los grupos humanos surgen o son creadas con diferentes propósitos, incluyendo el control social, la protección legal, el análisis social, la acción colectiva y la descripción coloquial. Estas delimitaciones pueden o no superponerse y coincidir. A veces, grupos objeto de discriminación se apropian, invierten y celebran etiquetas previamente peyorativas. Además, términos afines en diferentes idiomas no siempre son del todo equivalentes (por ejemplo, peasant, campesino, paysan, крестьянин [krest’ianin], etc.). Aunque las definiciones normativas parecen fijar un objeto de manera atemporal, en la práctica siemprecambian con el tiempo y suelen tener distintos grados de rigurosidad y laxitud.

Published: January 2022

Purpose: In the coronavirus disease 2019 pandemic, it is essential to supplement the changes in visiting patterns of individual emergency departments (EDs) to determine how to allocate emergency medicine resources. We compared the clinical features of children visiting the ED before and during the pandemic.Methods: Children younger than 18 years who visited the ED from February 2019 through December 2020, except January 2020, were enrolled, and divided into those who visited before and after January 2020 (the pre-pandemic and pandemic groups, respectively). We compared the 2 groups in terms of the baseline characteristics (age, sex, mode and route of arrival, cause of visit, and time of visit), chief complaint, ED diagnosis, initial acuity and its accuracy, and ED outcomes (length of stay and disposition).Results: The 31,036 children were categorized into the pre-pandemic (21,027 [67.8%]) and pandemic (10,009 [32.2%]) groups with a 52.4% decrease in the number of visits to the ED in the latter group. This decrease was more prominent in age 2-5 years (from 37.3% to 33.2%; P < 0.001), fever as a chief complaint (from 27.8% to 16.5%), diagnoses related to infection or the respiratory system (from 36.8% to 14.3%) or transfer to the ED (from 8.1% to 6.4%; P < 0.001). In contrast, increases were noted in age 12-17 years (from 14.9% to 17.4%; P < 0.001), injury (from 36.5% to 52.5%; P < 0.001), visits in the evening (from 54.9% to 57.4%; P < 0.001), length of stay longer than 6 hours (from 3.5% to 6.3%; P = 0.033), and low acuity (from 97.8% to 98.2%; P = 0.031).Conclusion: The pandemic has brought about changes in visiting patterns of the ED. This study may help prepare strategies for the appropriate allocation and deployment of emergency medicine resources in the pandemic era.

Published: January 2022

No Brasil, mais da metade dos municípios não possuem plano de saneamento básico. Essa situação atinge, de fato, a população socioeconomicamente mais carente, ocasionando o aparecimento de doenças por ingestão de alimentos crus ou mal lavados. O presente estudo teve por objetivo analisar a presença de parasitos, coliformes totais e termotolerantes em alfaces (Lactuca sativa) comercializadas em feiras livres em Jequié, Bahia. Entre os meses de agosto a outubro de 2019, as amostras foram obtidas aleatoriamente em três feiras livre, as análises foram realizadas pelo método de centrifugação simples e a pesquisa de coliformes utilizou o Método do Número Mais Provável. As amostras de alface analisadas nas feiras livres, 62,5% apresentaram contaminação por Ancilostomídeo, sendo a morfologia predominante larva e, em apenas uma amostra foi encontrado um ovo; além disso, foi possível constatar que 90,9% das amostras analisadas foram positivas para coliformes termotolerantes. A presença de Ancilostomídeo assim como a elevada contagem de coliformes termotolerantes em amostras de alfaces obtidas em feiras livres no município de Jequié, sinaliza a necessidade da implementação e adoção de medidas profiláticas durante o processo de comercialização das hortaliças.

Published: January 2022

In this study, the plant communities at five succession stages (herbage,
herbage-shrub, shrub, tree-shrub, and tree) in the Zhenning Karst
Plateau area of Guizhou were examined. The changes of plant functional
characteristics in different succession stages were analyzed, as was the
relationship between functional traits and environmental factors. The
main results include the following. (1) During the succes-sion process,
plant height, leaf dry matter mass, leaf area, leaf nitrogen content,
and leaf phosphorus content gradually increased, whereas leaf thickness
and specific leaf area decreased, and leaf C:P ratio and leaf N:P ratios
did not change significantly. (2) Soil organic matter, soil total
nitrogen, soil total phosphorus, soil C:N, soil C:P, and soil C:K
increased at first and then decreased, reaching a peak at the tree-shrub
stage. Soil total potassium fluctuated and soil bulk density gradually
decreased and reached the lowest value at the tree-shrub stage. (3)
Redundancy analysis (RDA) showed that the plant community shifted from a
nutri-ent-poor soil environment to a nutrient-rich environment. Soil
total phosphorus, soil C:K, soil organic mat-ter, soil C:N, and soil
bulk density were the key environmental factors affecting the change of
functional traits. (4) Structural equation modeling suggests that that
specific leaf area and leaf nitrogen content had more sensitive
responses to soil nutrient resources and environmental factors,
respectively.

Published: January 2022

Erythema nodosum (EN), the most form of panniculitis, is mainly caused
by numerous infective (especially Beta-hemolytic streptococcal
infections) and non-infective (especially sarcoidosis) diseases and
drugs. EN associated with vaccines has been rarely reported. We describe
herein, an original clinical observation of EN induced by BNT162b2, an
mRNA vaccine. A 75-year-old woman presented with diffuse erythematous
painful rounded nodular lesions, located symmetrically over her legs.
Six days before, she had received the second dose of Covid-19 vaccine
(BNT162b2 (Pfizer–BioNTech)), followed by a sudden asthenia,
polyarthralgia, throbbing and edema over her lower limbs. She had been
given the first dose of the same Covid-19 vaccine 29 days prior to the
second without incident. General physical examination was normal. Skin
examination showed multiple, erythematous tender, nodules, 10–30 mm in
diameter, over the tibial area. Complete blood count, renal and hepatic
tests, antistreptolysin O titer, antinuclear antibody, thyroid test and
chest radiograph and PCR, were carried out, and found to be normal.
Histopathology revealed infiltration of deep dermal vessels and
subcutaneous fat with lymphomononuclear cells and neutrophils,
consistent with erythema nodosum. Treatment with analgesics led to
complete resolution of the lesion after three months. The patient has
shown no relapse after follow-up for three months. In conclusion, to our
knowledge, this is the first case of EN induced by the second dose of
BNT162b2 (Pfizer–BioNTech) Covid-19 vaccine. It is important for
clinicians to be aware of this rare, yet potential, adverse effect to
this vaccine.
Dynamics and optimal control of a spatial diffusion HIV/AIDS model with ART and PrEP treatments
Authors: Wang Liping , Din Anwarud , Wu Peng
Published: January 2022

In this paper, to investigate the synthetic effect of PrEP (pre-exposure
prophylaxis) and ART (antiretrovial therapy) on HIV transmission among
MSM (men who have sex with men) in heterogenous environment, an
realistic HIV epidemic model with spatial diffusion is established.
Here, HIV infectious people are divided into three immunity based
compartments, i.e., CD4+ T cell count less than 350, between 350 and
500, and more than 500, respectively. The basic reproduction number
$R_0$ is established and proved as a threshold parameter: The global
asymptotic stability of the disease-free steady state holds for
$R_0<1$, and the disease will be present if
$R_0>1$. Considering the substantial advantages of PrEP
and ART in controlling HIV transmissions among MSM, the optimal control
problem is presented for the case of positive constant diffusion
coefficients, which minimize the total population of susceptible
individual and HIV infected individual, the cost of PrEP and ART
thearpy. As an illustration of our theoretical results, we conduct
numerical simulations. We also conduct an optimal control case study
where model parameters are estimated from the demographic and
epidemiological data from China. This work suggests: (1) Spatial factors
cannot be ignored during the HIV intervention; (2)Taking the PrEP
intervention measure for HIV transmissions among MSM as early as
possible will help to improve the control efficiency and reduces its
cost; (3) Reducing the PrEP drug costs will promote the efficiency of
PrEP treatment in preventing the spread of HIV among MSM.
Squalene epoxidase promotes hepatocellular carcinoma development by activating STRAP transcription and TGF-β/SMAD signaling
Authors: Yin Wu , zhang zhirui , Wu Wei , Jiao Hao , Chen Yuzhong , Ji Xiaojun , Cao Jing , Yin Fangzhou
Published: January 2022

Background and Purpose Squalene epoxidase (SQLE) is a key enzyme
involved in cholesterol biosynthesis, but increasing evidence reveals
that SQLE is abnormally expressed in some types of malignant tumors, and
the underlying mechanism remains poorly understood. Experimental
Approach Bioinformatics analysis and RNA sequencing were applied to
detect to differentially expressed genes in clinical HCC tumors.
AnnexinV-FITC/PI, EdU assay, transwell, IHC staining, cytoskeleton
F-actin filaments assay, RNA sequencing, dual-luciferase reporters and
HE staining were evaluated to investigate the pharmacological effects
and possible mechanisms of SQLE. Key Results We found that SQLE
expression is specifically elevated in HCC tumors, correlating with poor
clinical outcomes. SQLE promoted HCC growth, EMT, and metastasis both in
vitro and in vivo. In contrast, silencing of SQLE expression prevented
HCC development. Both RNA-seq and functional experiments revealed that
the protumorigenic effect of SQLE on HCC is closely related to the
activation of cellular TGF-β/SMAD signaling, but interestingly, the
stimulatory effect of SQLE on TGF-β/SMAD signaling and HCC development
is also critically dependent on STRAP, a serine and threonine kinase.
SQLE expression is well correlated with STRAP in HCC, and further, to
amplify TGF-β/SMAD signaling, SQLE even transcriptionally increased
STRAP gene expression mediated by the trans-acting factor AP-2α.
Finally, as a chemical inhibitor of SQLE, NB-598 markedly inhibited HCC
cell growth and tumor development in mouse models. Conclusions and
Implications Taken together, SQLE serves as an oncogene in HCC
development by activating TGF-β/SMAD signaling, and targeting SQLE could
be useful in drug development and therapy for HCC.

Published: January 2022

The organic food market is rapidly expanding all over the world with the recent rise of concern in food safety and environmental protection. Thus, examining information about consumers’ awareness on organic food is one of the inspiring areas for producers and marketers to capture a greater market share successfully. Therefore, this study aimed at analyzing the consumer awareness towards organic food products while addressing socio-demographic factors affecting consumer awareness on organic food, knowledge of consumers about organic food, and their purchasing pattern. A sample of 600 consumers was selected from the main cities of six urban districts in Sri Lanka for the study. Data were collected via a consumer survey using a pre-tested questionnaire, from November 2018 to May 2019. The data analysis was carried out using frequencies, percentages, and multiple linear regression analysis. According to the results, the majority of the respondents were married females. The results revealed that Sri Lankan consumers have a better awareness on organic food. The results of the regression analysis highlighted that the consumers’ awareness is significantly affected by factors such as gender, marital status, education, and monthly income. Although most respondents have a good level of awareness on organic food, their buying trend is at a lower level. The findings of the study play an important role in promoting the organic food market and are essential for food marketing planners, researchers, and policymakers to enhance the organic food industry in the country in the future.
Analytical study of the section of the rc beams strengthened for flexure with FRP materials

Published: January 2022

Strengthening of concrete structures is applied as a solution for various
deterioration problems in civil engineering practice. This paper presents an
analytical study of the behaviour of cross-section of reinforced concrete
(RC) beam, strengthened for flexure with fiber reinforced polymer (FRP)
materials. Using the balance of internal forces in the cross section through
all phases of stress through which the section passes, a program was written
in the MATLsoftware, the execution of which produced a curve of
dependence between bending moment and curvature, which is one of the most
important indicators of cross section behaviour. The parameters varied in
this study are the amount and type of FRP reinforcement and the obtained
results indicate a significant influence of additional FRP reinforcement
both on the yielding and ultimate bending moment, and on the bending
stiffness of the strengthened cross section.

Published: January 2022

Gender identities are expressions of masculine or feminine natures and
interpreted within socio-cultural contexts. In this study, gender
identities, domestic space utilisation and gender roles among staff of Osun
State University, Osogbo, Nigeria were identified and analysed. With the aid
of pre-tested questionnaires, primary data were collected using multi-stage
sampling technique from 222 out of 675 staff members of Osun State
University Osogbo. Secondary data were obtained from the Academic Planning
Unit of the University and Osun State Ministry of Lands and Physical
Planning. Descriptive statistics such as frequency and percentage tables,
cross tabulation, and Bem Androgyny Model were utilized for the analysis of
data obtained. Findings on individual gender identities showed that 1.3% of
the respondents were masculine, 36% were feminine while 62.7% of the
respondents were androgynous. Majority of the males and females were
androgynous however some males were feminine although no female was
masculine. Remarkably, only 2.2% of the males were masculine. These findings
further confirm that most individuals possess a combination of feminine and
masculine traits known as androgyny, and that individuals? gender identities
do not necessarily correspond with their biological sex. Results also showed
that domestic space utilisation and domestic gender roles varied with
individual gender identities rather than just gender (being male or female).
The study concluded that gender identities are important to the concept of
gender-integrated housing design. Therefore gender-responsive housing
designed to equitably meet the needs of men and women should be encouraged.

Published: January 2022

Introduction/Objective. Comparing two materials under the same conditions is the best way to define differences between them. Ceramic-reinforced polyether-etherketone (PEEK) is a polymer that has many possible uses in dentistry as already well-known lithium disilicate ceramics. The aim of this study was to compare peri-implant soft tissue healing and evaluate patient satisfaction with esthetics in different observation periods, as well as the success and survival rate of both types of crowns. Methods. The study was conducted as a clinical, prospective, randomized split-mouth study on 17 patients with bilaterally missing upper teeth of the same type, replaced with dental implants. Study outcomes have been analyzed with subjective (visual analogue scale ? VAS scale) and objective parameters (modified bleeding index ? MBI, modified plaque index ? MPI and peri-implant probing depth ? PPD) baseline, six and twelve months after fixing crowns onto the implants. Results. Comparison of the results between PEEK and lithium disilicate crowns showed no statistical differences in terms of MPI, MBI, and PPD in the observed periods. Analyzing MPI during observation periods in the PEEK group of crowns, statistical significance was registered between baseline values and after six months. Also, statistical significance was noticed in terms of PPD during the observation time both in the study and control group of crowns. Results for VAS for the esthetics showed no statistically significant difference between the groups, while VAS for restoration satisfaction showed a statistically significant difference. Conclusion. This study showed that scores of the applied subjective and objective parameters can be a reliable tool to rate the clinical outcome of implant-retained single crowns over time.

Published: January 2022

This study aims to propose a sustainable electricity mix option for Turkey by 2030. First, the electricity demand of Turkey by 2030 is estimated by employing a method that comprises MLP ANN and GPRM. Population, GDP, imports, exports, and IPI are considered independent variables used in the ANN model. The future values of each of the independent variables are predicted by a GPRM model based on a univariate time series approach. ANN model is then employed to predict electricity demand based on the future values of independent variables. Secondly, four diverse electricity mix scenarios are developed considering the forecasted electricity demand. The sustainability evaluation of the scenarios is performed using TOPSIS method considering ten different criteria classified into environmental, economic, technical, and social categories. Furthermore, four diverse weight sets are determined for the given categories, and also a sensitivity analysis is carried out. Turkey’s electricity demand is found out as ≈ 384,569 GWh according to the prediction for the year 2030. The Scenario-(C), which has a comparatively higher percent of nuclear energy generation, is determined as the most sustainable electricity mix scenario according to evaluation with the TOPSIS method.

Objective: Frame Running (RaceRunning) allows people with moderate-to-severe mobility impairments to participate in physical activity using a 3-wheeled frame with a saddle and handlebars. The aim of this study was to investigate athlete-perceived impact of Frame Running on aspects of physical fitness, functional mobility and psychosocial outcomes.Design: Survey.Participants: Frame Running athletes aged 5 years and over.Methods: A survey was distributed to athletes through their club or sports organization.Results: The survey was completed by 115 athletes (53 females). Median age was 17 years (range 5–62 years) and 64 (57%) used a wheelchair or walker for distances over 50 m. Many felt that Frame Running stretched their muscles (n = 93, 87%) and increased their self-confidence (n = 63, 93%). Four (4%) reported extreme fatigue or sore muscles after training (n = 17, 15%). Of the 110 athletes who had been participating in Frame Running for over 3 months, 46 (47%) reported being less out of breath during mobility tasks and 66 (66%) felt they had improved their functional mobility. However, 7 (7%) reported increased muscle tightness and 4 (4%) reported a Frame Running-related injury lasting more than 4 weeks.Conclusion: Frame Running is a safe physical activity with athlete-perceived benefits on physical fitness, functional mobility and psychosocial outcomes.
Lay abstractFrame Running (RaceRunning) allows people with moderate-to-severe walking difficulties to walk or run independently using a 3-wheeled frame with a saddle and handlebars. In this study 115 Frame Running athletes living in the UK, Sweden or the Netherlands and aged 5 years or over (or their parents) completed a survey about taking part in Frame Running. More than half used a wheelchair or walker for distances over 50 m. Most felt that Frame Running stretched their muscles and increased their self-confidence. Four athletes perceived extreme fatigue and 17 reported sore muscles after training. Approximately half of the athletes reported that they were less out of breath during mobility tasks (walking, standing) and two thirds reported better functional mobility since they had started Frame Running. Injuries lasting more than 4 weeks were reported by 4 athletes. We conclude that Frame Running is a safe activity with the potential to improve physical fitness, functional mobility, and self-confidence.

Published: January 2022

It is well-known that the exposure of bacteria and germs to electromagnetic radiation can lead to their annihilation. In this work, we have attempted to characterize the effect of laser radiation on test samples comprising bacteria and bacteriophages. A pulsed transverse excitation atmosphere CO2 laser that operates in the mid-infrared region of the electromagnetic spectrum has been employed for the studies. Aeromonas bacterium and its specific virus, P2 bacteriophage, cultured on a typical matrix of tryptic soya agar, served as the test samples. Agar overlay technique was used to examine the test results. A detailed analysis of the laser-exposed samples showed a complete neutralization of Aeromonas bacteria and its bacteriophage for appropriate laser parameters. Since bacteriophages are extensively used as a surrogate organism to study virucidal effects, it is anticipated that exposure to CO2 laser radiation will have a similar effect on SARS CoV2 and viruses of similar nature.

Published: January 2022

Since the increase of Indonesian people exposed to Covid-19 was massively reported, our government has tried to find best solution to overcome this situation, one of them is conducting online learning for the students. At STIA Nusa, English learning which was originally done offline, was changed to online with the obligation to use several online media applications such as Zoom, Edmodo and Whatssap. The purpose of this study was to look at the students’ perception and ask the results of their English skills as well as offline learning. This research used qualitative, with data collection techniques are interviews with 128 students. The research results showed that 1). Zoom presents a new learning model even though most of them still say the lack of interaction, 2). The use of Edmodo for  them is more interactive because they are able to repeat lessons and discuss with friends if there is a lack of understanding about learning and its user friendly features such as Facebook 3) the use of WhatsApp groups makes it easier for them to ask questions with the lecturer and through the voice note feature the lecturer can provide feedback what they need and through this application students can be rewarded so that it gives them the motivation to learn more during the pandemic.

Whose Bay Street? Competing Narratives of Nassau’s City Centre
Authors: Patara Martin Nona
Published: January 2022

Bay Street has always been at the centre of commercial, cultural and political life in the Bahama Islands. It also acts as a gateway for millions of tourists who come to Nassau, the Bahamian capital, via cruise ships every year. Not surprisingly, Bahamians and non-Bahamians have widely divergent impressions of Bay Street. The need to accommodate the tourists who are critical to the Bahamian economy has meant that Bay Street, despite its deep social significance for Bahamians, has increasingly become a tourist space. With reference to the ‘sense of place’ and place attachment literature, this paper traces the transformation of Bay Street and attempts to tease out the most obvious tensions between the Bay Street that Bahamians experience and Bay Street as a port of call.

The requirements of the debris flows’ parameters assessments vary from country to country. They are based on different theoretical and empirical constructions and are validated by data from different regions. This makes difficult comparison of the reported results on estimated debris flows activity and extent. The Russian normative documents for the debris flows’ parameters calculations are based on empirically-measured parameters in wide range of geological and climatic conditions at the territory of former USSR, but still not cover all the possible conditions of debris flow formation. An attempt was made to check applicability of the Russian empirical constructions for the conditions of the debris flows formation in Yunnan, China, where unique long-term dataset of debris flows characteristics is collected by the Dongchuan Debris Flow Observation and Research Station. The results show, that in general the accepted in Russia methodology of calculation of the parameters of debris flows of certain probability corresponded well to the observed in Dongchuan debris flows characteristics. Some discrepancies (in the average debris flow depth) can be explained by unknown exact return period of the actually observed debris flows. This allowed to conclude that the presently adopted empirical dependencies based on country-wide (USSR) empirical data can be extrapolated up to the monsoon climate and geological conditions of Yunnan province.
GIS-Analysis Of The Ural Power Grid Vulnerability To The Impact Of Sleet And Wind

Published: January 2022

In this paper, we describe an experiment of complex power grid structure and wind and sleet mapping of territory using two different network indices: standard edge betweenness centrality and new author’s index – electrical grid centrality. Such analysis of the network allows to identify power lines with high load which could be vulnerable elements of the power grid. It is very important for strategic planning of power grids to reduce the risk of accidents by distributing loads across several lines so that they will be able to reserve each other. As a case territory for this research, we took the Ural united power system in Russia which is greatly exposed to different sleet and wind according to the statistics of the power grid operator. The degree of natural hazard consequences could be compensated by the network structure through alternative paths of energy supply or vice versa – increased if they are absent. At the same time, in this paper we consider that power grids have their own features from the graph theory point of view, for example multiple (parallel) edges, branches, different types of vertices. The existing index of edge betweenness centrality does not perfectly cope with them. We compare two indices characterizing power line importance within the system – betweenness centrality and electrical grid centrality and analyze the network structure features together with the spatial distribution of sleet and wind. As a result, we could identify bottlenecks in the study network. According to this study the most vulnerable power lines were detected, for example 500 kV Iriklinskaya CHP – Gazovaya and 500 kV Yuzhnouralskaya CHP-2 – Shagol power lines, that supply big cities such as Chelyabinsk and Orenburg and a bunch of industries around them.

DEMOCRACIA RADICAL E SUBSTANTIVA EM PAULO FREIRE: da escola para o mundo e do mundo para a escola
Authors: Di Giorgi Cristiano Amaral Garboggini , Militão Andréia Nunes , Perboni Fabio
Published: January 2022

Este texto analisa a acepção freiriana de democracia radical e substantiva como premissa fulcral para uma formação humana emancipatória. Tem-se como pressuposto que a construção da democracia na escola está amalgamada à democratização da sociedade da qual faz parte. Elege-se Paulo Freire como autor de referência e localiza-se outros autores da atualidade que têm tratado deste tema. Constata-se que existem muitas semelhanças entre a concepção de uma sociedade democrática em Freire e em outros autores, notadamente como Chantal Mouffe, aspecto fundamental para a compreensão do cenário contemporâneo e igualmente da democracia escolar e seus desafios.
