Published: August 2021

When developing a novel conservation assessment, tradeoffs between generality and precision, and between realism and simplicity, will inevitably need to be made. Engaging potential end-users during development can help developers navigate these tradeoffs to maximise uptake. End-user engagement can also produce feedback about external perceptions, allowing changes to be made prior to the final design. Here, we report on end-user consultations about the species recovery assessment method introduced by the International Union for Conservation of Nature (IUCN), which is a new component of the IUCN Red List of Threatened Species. This species recovery assessment was originally called the ‘Green List of Species.’ We conducted two types of end-user consultation over a two-year period—1) key informant interviews, and 2) technical consultations about the details of the assessment method, including identification of factors that increased the amount of time required to conduct an assessment. A main finding from the key informant interviews was that the name ‘Green List of Species’ was inappropriate for the assessment, given the potential for misunderstanding the scope of the assessment and potential confusion with the IUCN Green List of Protected and Conserved Areas. We therefore proposed the name ‘Green Status of Species', a suggestion accepted by IUCN. A repeated concern in key informant interviews was the perception that the species recovery assessments were complex, indicating a potential tradeoff between scientific rigour and simplicity. To address this concern, we used feedback from the technical consultations to identify assessment steps which were most in need of refinement, and implemented solutions and made recommendations to streamline those steps (e.g., we found that the number of spatial units used in an assessment was positively correlated with assessment time, and increased greatly when more than 15 spatial units were used). This process of end-user engagement makes it much more likely that the Green Status of Species will be used in conservation communication, monitoring, and decision-making—helping achieve the ultimate goal of biodiversity recovery.
Statin-Induced Toxic Rhabdomyolysis with Hepatocellular Jaundice in the Elderly

Published: August 2021

Adverse drug reactions (ADRs) are a common cause of hospitalization, increased morbidity and mortality in the elderly. ADRs are difficult to diagnose in the elderly as they often present with nonspecific symptoms such as fatigue, falls, cognitive decline, and constipation. Statins are generally well-tolerated drugs used in the secondary prevention of coronary artery disease. We report a 75-year-old lady who developed jaundice and became bedbound due to statin-induced hepatitis and acute rhabdomyolysis causing proximal myopathy following initiation of atorvastatin 40 mg for the management of coronary artery disease. She had rapid clinical improvement with discontinuation of statin therapy and supportive management. ADR must be considered a part of differential diagnosis in elderly patients during the evaluation of illnesses. In the elderly initiated on statins, it is essential to differentiate benign muscle pain from severe muscle injury with biochemical abnormalities. Prompt discontinuation of statins will lead to rapid improvement and prevent further worsening.
Ventilator-Associated Pneumonia
Authors: Dhingra Arti , Bhatt Sonia , Kashyap Rajesh
Published: August 2021

Background:

The profile and pattern of ventilator-associated pneumonia (VAP) varies among different settings, depending on the definition, the type of hospital or intensive care unit (ICU), the population studied, and the level of antibiotic exposure.

Aim:

We aimed to study the profile and pattern of VAP among mechanically ventilated children admitted to a pediatric ICU.

Methods:

Critically ill children aged 1 month to 12 years of age, who received mechanical ventilation and developed VAP, were included in the study. The VAP was diagnosed using the Clinical Pulmonary Infection Score. The Pediatric Index of Mortality 3 (PIM-3) was also calculated. Categorization of diagnosis was done based on PIM-3 guidelines. The mean length of stay duration of mechanical ventilation was also noted down.

Results:

The incidence of VAP in the present study was 37.78%. PIM-3 was 2.24. The mean length of stay in cases of early VAP was 8.14 days, whereas it was 20.3 days in late VAP. Two important conditions that led to the development of VAP were respiratory conditions (33.33%) and neurological conditions (27.45%). Liver injury and renal injury were noted in 14 (27.5%) and 10 (19.6%) patients. Significant differences were observed in the mean length of stay and in cases of reintubation. The three most common organisms seen were methicillin-resistant Staphylococcus aureus (MRSA), Acinetobacter, and Klebsiella along with Pseudomonas, whereas among nonsurvivors, they were Candida, Citrobacter, Enterococcus spp., methicillin-resistant coagulase-negative staphylococci, and Streptococcus.

Conclusion:

VAP is a common entity among ventilated children. Cases of late VAP face a longer length of stay on mechanical ventilation. Parenteral nutrition and the presence of nasogastric tubing were significantly associated with late-onset VAP as compared to early VAP. Three most common organisms seen were MRSA, Acinetobacter, and Klebsiella along with Pseudomonas.

Diarrheal disease accounts for more than one million deaths annually in patients over 5 years of age. Although most patients can be managed with oral rehydration solution, patients with severe dehydration require resuscitation with intravenous fluids. Scoring systems to assess dehydration have been empirically derived and validated in children under 5 years, but none have been validated for patients over 5 years. In this study, a prospective cohort of 2,172 patients over 5 years presenting with acute diarrhea to International Centre for Diarrhoeal Disease Research, Dhaka Hospital, Bangladesh, were assessed for clinical signs of dehydration. The percent difference between presentation and posthydration stable weight determined severe (≥ 9%), some (3–9%), or no (< 3%) dehydration. An ordinal regression model was derived using clinical signs and demographics and was then converted to a 13-point score to predict none (score of 0–3), some (4–6), or severe (7–13) dehydration. The Novel, Innovative Research for Understanding Dehydration in Adults and Kids (NIRUDAK) Score developed by our team included age, sex, sunken eyes, radial pulse, respiration depth, skin turgor, and vomiting episodes in 24 hours. Accuracy of the NIRUDAK Score for predicting severe dehydration, as measured by the area under the receiver operating characteristic curve, was 0.76 (95% confidence interval = 0.73–0.78), with a sensitivity of 0.78 and a specificity of 0.61. Reliability was also robust, with an Inter-Class Correlation Coefficient of 0.88 (95% confidence interval = 0.84–0.91). This study represents the first empirically derived and internally validated scoring system for assessing dehydration in children ≥ 5 years and adults with acute diarrhea in a resource-limited setting.

Published: August 2021

Due to the ever-increasing demand for water in Aynalem catchment and its surrounding, there has been an increased pressure on the Aynalem well field putting the sustainability of water supply from the aquifer under continuous threat. Thus, it is vital to understand the water balance of the catchment to ensure sustainable utilization of the groundwater resource. This in turn requires proper quantification of the components of water balance among which recharge estimation is the most important. This paper estimates the groundwater recharge of the Aynalem catchment using high-resolution hydro-meteorological data. Daily precipitation and temperature measurement data for years 2001-2018; groundwater level fluctuation records collected at every 30 minutes; and soil and land use maps were used to make recharge estimations. In the groundwater level fluctuation, three boreholes were monitored, but only two were utilized for the analysis because the third was under operation and does not represent the natural hydrologic condition. Thornthwaite soil moisture balance and groundwater level fluctuation methods were applied to determine the groundwater recharge of the Aynalem catchment. Accordingly, the annual rate of groundwater recharge estimated based on the soil-water balance ranges between 7mm/year and 138.5 mm/year with the weighted average value of 89.04 mm/year. The weighted average value is considered to represent the catchment value because the diverse soil and land use/cover types respond differently to allow the precipitation to recharge the groundwater. On the other hand, the groundwater recharge estimated using the groundwater level fluctuation method showed yearly groundwater recharge of 91 to 93 mm/year. The similarity in the groundwater recharge result obtained from both methods strengthens the acceptability of the estimate. It also points out that the previously reported estimate is much lower (36 to 66 mm/year).

O artigo tem como proposta discutir a partir de alguns conceitos de Frederick Barth (2005), Pierre Bourdieu (1989), Nancy Fraser (2001) e Michel Foucault (1990) determinadas situações sociais planejadas pelo Estado no país. Aplico as formulações dos autores para levantar questões e reflexões acerca das políticas públicas em contextos sócio - culturais de desigualdade e injustiça. Partindo de um caso particular, através de algumas consequências da construção do canal da transposição das águas de Rio São Francisco no contexto da cidade de Monteiro - PB, evoco certos efeitos colaterais desta agência pública que reverberaram em "políticas racionais de Estado" que interferiram nas práticas cotidianas e culturais de algumas famílias e moradores desta cidade. Neste sentido, o presente trabalho tem o objetivo de fazer reflexões sobre o projeto de transposição, o qual são e foram operacionalizadas pelo Estado. Assim, portanto, tendo por base os relatos e a experiência de vida de dois moradores da cidade de Monteiro - PB, explicitarei as mudanças ocorridas no cotidiano dos moradores e seus modos de vida, após a inauguração da transposição.
The Importance of Explicit and Timely Knowledge Exchange Practices Stemming from Research with Indigenous Families
Authors: Cooper Elizabeth , Driedger S Michelle
Published: August 2021

Ethical research practice within community-based research involves many dimensions, including a commitment to return results to participants in a timely and accessible fashion. Often, current Indigenous community-based research is driven by a partnership model; however, dissemination of findings may not always follow this approach. As a result, products may not be as useful to participants who were motivated to be involved in the research process. We conducted a seven-week workshop on three occasions with different First Nations and Metis women and girls (age 8-12) in Winnipeg, Manitoba. The workshop explored participants’ perspectives around health, safety, and family wellbeing using a strength-based, participatory approach. Participants noted that a key challenge they face when interacting with researchers, policy makers, and program staff is the lack of tailored dissemination materials. Returning results in a format that meets the expressed desire of participants is an ethical necessity to ensure that research is not perpetuating past colonial practices. Doing so quickly and with meaningful content requires careful execution and consideration, especially when working within intergenerational contexts. We describe in this paper how results were returned to families in an accessible way outlining the role that integrated knowledge exchange can play in the process of healing.

Hemangiosarcoma is a neoplasm which originates from the vascular endothelium, presenting itself in two distinct forms, visceral and non-visceral. The visceral form occurs mainly in the spleen, with main foci of metastasis in the lungs, liver, omentum and mesentery, affecting the central nervous system in rare cases. The present study reports on a case of hemangiosarcoma in a bitch, with cutaneous and central nervous system involvement. The animal presented important neurological signs with an acute clinical evolution, and was submitted to euthanasia. Necroscopic examination revealed multiple cutaneous nodules and masses in the brain and spinal cord, which were submitted to histopathological examination. The final diagnosis was hemangiosarcoma.

Published: August 2021

Soil erosion in southeastern Nigeria has a high devastating tendency which created a natural geologic hazard is causing loss of arable farm lands, destroying properties and other social infrastructures like pipelines, roads, bridges, over head and underground cables that are being exposed and or washed away by deep gully erosions. Investigations into the underlying factors of soil susceptibility to soil erosion in southeastern Nigeria led to this work. The study areas are the twenty six Local Government Areas within the centre of the zone which are Anaocha, Orumba North, Aguata, Nnewi South and Orumba South in Anambra State; Umunneochi, Bende, Ohafia, Arochukwu and Isuikwuato in Abia State; Afikpo North, Afikpo South, Ivo, Ohaozara and Onicha in Ebonyi State; Aninri, Oji River, Ezeagu, Udi and Awgu in Enugu State, and Idea to North, Idea to South, Okigwe, Orlu, and Orsu in Imo State. The dataset for this research work are from secondary and primary sources. Secondary Data were extracted from other journal publications among others, while primary data were in the form of measurement during field visit, photographs and geophysical soil survey and verification. Descriptive Statistics, Student t-test and Chi-square test analysis were used. The result shows that the soils across the study area generally are predominantly sandy with a mean of fine sand at 28.22% and coarse sand at 43.40%, while the mean of clay and silt are very low, 17.82% and 10.56% respectively. The study concludes that high sand content in the composition of soil in the study area is responsible for high rate of soil erosion in the area and therefore recommends a policy framework from the government of Nigeria that will encourage a paradigm shift from roots and tubers crop production that exposes the soil, to orchard plantation.

Published: August 2021

The objective of the study is to know whether creditors terms and Micro, Small and Medium Enterprises (MSMEs) accounting process affect MSMEs debtor’s management and to know the need for novel Information Technology (IT) tools. This study proposes a definite set of survey questionnaires to measure variables such as the influence of suppliers’ credit policies and the accounting process of selected MSMEs. The sample size of this study focuses on various MSMEs owners or accountants in Oman. The questionnaire survey findings are based on 44 MSMEs that responded. The study used Partial Least Squares Structural Equation Modeling (PLS-SEM) to analyze creditors terms, accounting process of MSMEs with its impact on MSMEs debtors’ management. MSMEs' accounting process and suppliers' credit policies do influence MSMEs debtors’ management. Increased working capital risks due to inefficient debtors’ management may lead MSMEs to be resource-efficient in managing their accounting process by using IT tools. The practice of using IT tools by MSMEs can scientifically manage their outstanding debtors which leads to a higher level of hostile working capital management and MSMEs sustainable development. MSMEs play a key role in the development of the national economy, there is a dearth of similar published MSMEs broad studies in Oman that validates the importance of the current research.

Published: August 2021

The art of learning, unlearning and relearning is the need of the hour, and these are indispensable in any field for professional growth. Especially in the educational sector, change leads to development initiatives and raising standards in teaching and learning. Interestingly, the existing opportunities provide more options for Continuing Professional Development (CPD) activities and programmes for teachers and professors. The present study analyses teachers and professors’ responses to CPD activities and offers a wide range of information and opinions on CPD programmes and activities. A phenomenological approach was employed to study 257 participants’ perspectives from 48 countries through a questionnaire. This research will also be a resource for teachers and professors seeking professional development in the field. The responses revealed that teachers and professors were eager to take responsibility for participating in CPD activities with mutual support and guidance from the management. The institutions are responsible for ensuring faculty opportunities, particularly for young teachers in their early stages of teaching, and they must be assisted in acquiring the necessary knowledge and exposure. This research paper presents the state of CPD activities, programmes, challenges and awareness across the world.

Published: August 2021

Purpose: Using a Systems’ Approach, this study explores what aspects are essential for stone quarries to adopt a functional environmental management plan and whether compliance with environmental laws enhances business performance. The specific objectives of the study were: To evaluate the bio-physical effects of quarrying activities in selected quarries in Tezo ward and to evaluate the socio-economic effects of quarrying activities in selected quarries in Tezo ward.

Methodology: The study adopted descriptive survey design; the research data collection instrument was questionnaires. The study adopted purposive sampling; a survey of 134 respondents representing 80 quarry workers, 40 quarry owners, 10 EIA Experts, 3 NEMA staff and 1 County geologist were sampled purposively. Weighted and the Consolidated Scores were entered on Microsoft Excel for cleaning and later transferred to Statistical Package for Social Sciences (SPSS version 23.0) for statistical analyses. Data was presented inform of graphs, pie-charts, tables and narration in the thematic areas.

Findings: The study found out that there were health and ecological problems associated with quarrying. The application of heavy quarrying machines resulted to soil erosion, destruction of flora and threatens biodiversity aesthetic. The study revealed that quarrying was a source for livelihood among the community and more men (90%) were involved in quarrying due to masculinity nature of the task. EMPs were found to be significant in management of quarries. The development of EMPs and EIA was influenced by different actors and informal sector was a significant influencer of EMPs implementation. The study concluded that EMPs were effective in management of quarries despite varied challenges facing the NEMA official and the EIA experts.

Unique contribution to theory, practice and policy: The study recommends the need for transparency in the EIA as well as in the development of EMPs, to avoid discrimination and non-adherence. Further research is needed to understand the perception of community members on the effectiveness of EMPs in sustainable management of quarries and environment in general.

Published: August 2021

Today, organizations not only need to manage larger volumes of data, but also generate insights from existing data. These insights help them understand better about their customers and predict market trends. With this initiative, they can take advantage of the cloud platform to achieve this goal because it manages higher data volume, speed and variation. This cloud platform enables them to provide elasticity and efficient computing and storage resources. They also provide many ready-to-use tools for building data analytics in various stages. Additionally, an on-demand pricing model allows organizations to pay for what they consume. It changes the organizational consumption model from capital expenditure to operational expenditure. It greatly minimizes initial capital investment to build data analytics solutions and implement other innovative ideas. This paper highlights the main reasons for encouraging organizations to build data analytics in the cloud. It also shows how to articulate data analytics frameworks for ecommerce platforms in the cloud and how to integrate machine learning models into data analytics processes, to create more sophisticated analyzes. AWS Amazon Web Services' premier public cloud platform is adopted to demonstrate these concepts and practices with real-life business cases.
The Internet, The Cloud, and Information Technology Governance
Authors: Asgarkhani Mehdi
Published: August 2021

Information Technology Governance (ITG) has become a catalyst for strategic evaluation and deployment of IT solutions. Much of the concepts, the mechanisms, the processes, the frameworks, and the standards of ITG date back to the 1990s. A review of recent studies indicates an increased uptake of ITG practices within organizations – mostly via the adoption of ITG standards and frameworks. Within the last decade, we have witnessed rapid technological advancements which have in turn motivated radical changes in the management of IT infrastructure, deployment of IT applications, and delivery of IT services. For instance, Data Centers and Cloud Services have transformed the paradigm of infrastructure and application management in the IT sector. Moreover, sophisticated smart mobile solutions have made it possible to develop IoT solutions enabling smart cities and smart building initiatives. A review of timelines when ITG concepts and standards established suggest that they originated years before recent transformations in technology adoption took place. Some ITG standards show that the adoption of some cloud services motivated revision in some ITG frameworks. This study demonstrates that there is a possibility that some of the current ITG standards are not fine-tuned to reflect recent developments in the adoption of IT solutions and services.

The Elegest-Mezhegei, Aptara, and Shivilig forecasted gold ore clusters and the Kharalyg and Irbitei forecasted gold-silver-polymetallic ore clusters were distinguished within the East Tannu-Ola iron-copper-polymetallic-gold ore region, based on examination of historical and new geological, geochemical, and metallogenical data. Subsequently, the Urgailyg, Proezdnoe, and Chumurtuk forecasted gold ore fields were delineated within the Elegest-Mezhegei cluster; the Despen ore field was delineated within the Aptara ore cluster; and the Ovur-Ongesh ore field was outlined within the Shivilig cluster. In addition, the Ulug-Sailyg and Ak-Charinsk gold-molybdenum-copper ore fields were distinguished outside the ore clusters. The article summarizes the investigation history, geological-structural position, geological features, and geochemical specialization of the rocks of the East Tannu-Ola region. Descriptions of the ore clusters embrace peculiarities of their geological structure, ore mineralogy, and native gold, as well as parameters of the gold-sulfide-quartz, goldskarn, gold-containing polymetallic VMS, and porphyry molybdenum-copper mineralized zones. The conclusions highlight the metallogenic epochs and distribution regularities of the gold and gold-containing mineralization within the region studied.

Mother Earth is terribly sick today, and what has muddied the waters is the unwelcomed visit of the one-eyed novel Coronavirus (Covid-19). It is another symptom of the serious diseases the planet is suffering from. It is like a heavy disaster that has ravaged everything in its path, killing thousands and thousands of people and causing countless of harmful effects; some of them are terribly damaging and detrimental while others are more or less considered as blessings in disguise. It is spreading day after day like a wildfire in every nook and corner of the world with no possible curative vaccine so far. Nonetheless, and regardless the pains, I feel that there is always something good in every bad situation even if may not seem like for a lot of people as the quote goes” Every day may not be good, but there is something good in everyday”. It is so obvious that with the current pandemic many positive and unexpected things are floating over the surface. Examples of these blessings include “reduction in air pollution 20-30% in many cases in major cities around the world” (Airborne Nitrogen Dioxide Plummets Over China, 2020). Currently, the skies are bluer, the environment is cleaner and even people seem to be more responsible than any time before. In addition, we notice the perceptible decline in the number of traffic crashes as “Fraser Shilling, director of the Road Ecology Center at the University of California at Davis, found that highway accidents—including those involving an injury or fatality—fell by half after the state’s shelter-in-place order on 19 March”. (Shilling F, 2020). Moreover, People have understood that health is better than any other wealth because it is the most precious gift one can own. Furthermore, we have learnt to keep going in sadness and sorrow as Roy T. Bennett explains, “Your hardest times often lead to the greatest moments of your life. Keep going. Tough situations build strong people in the end”. (Bennett, 2020). Besides, for us as learners and educators, the priceless gift of this pandemic is distance learning, which is another suitable alternative to bridge the distance with the learners and assure the continuity of their education as an urgent response to the actual health emergency. If the virus has succeeded to shut schools and quarantine people all over the globe, it surely won’t prevent learners to seek knowledge.
DISTANCE LEARNING, TEACHING AND EVALUATION STRATEGIES IN THE SUBJECT OF “CREATIVE WORKSHOP” FOR EARLY CHILDHOOD
Authors: KHALED Maha Mohammad
Published: August 2021

The Corona pandemic (covid19) imposed itself on the world in 2020, which called for rapid action to find distance educational solutions, with an experimental approach aimed at the quality and development of learning. It has obligated lecturers in universities of all subjects to learn to use distance learning techniques and to adapt to them, by identifying strategies of distance education, learning and evaluation and linking them to learning outcomes. These strategies are influencing factors in the success of the e-learning programs (from Zoom Microsoft and others), as alternative programs through which we seek to achieve quality in the distance learning process with the creative workshop subject. The requirements of these modern applications in higher education necessitate focusing on choosing distance learning strategies that lead to active learning and highlight the role and effectiveness of the learner. Teaching, learning and evaluation strategies vary differ from one program or course to another as a result of their different nature, so this modern method must be implemented on the teacher and the learner professionally in order to compensate for the lack of direct communication. The research tries to present the most prominent and appropriate strategies of teaching, learning and evaluation in the subject of the creative workshop for early childhood online, up to the mutual evaluation, in addition to detailing the difficulties and obstacles and how to overcome them.

Género e cidadania na educação pré-escolar: Vivências em tempo de pandemia no contexto português
Authors: Cardona Maria João
Published: August 2021

Em Portugal a educação pré-escolar destina-se às crianças dos 3 aos 6 anos, idade de entrada na escola obrigatória e as Orientações Curriculares em vigor foram definidas em 2016. No trabalho de pesquisa que tenho vindo a desenvolver a preocupação com a forma como na educação pré-escolar é dado realce ao trabalho sobre as questões de género, numa perspetiva de educação para a cidadania, tem sido uma prioridade. Em 2020 perante as necessidades decorrentes da pandemia (COVID19) a Associação dos Profissionais de Educação de Infância (APEI), recolhendo vários contributos, organizou um texto de apoio que se enquadra no que está definido nas orientações curriculares. Partindo da análise destes documentos, fazendo o seu devido enquadramento na realidade portuguesa, será analisado como é que as questões de género são trabalhadas na educação pré-escolar; como é que este período tão dificil está a ser vivenciado por meninos e meninas, ouvindo os seus testemunhos e os testemunhos de educadoras/es e investigadoras/es ligados à formação que têm acompanhado o processo de construção e divulgação das atuais orientações curriculares.
