Determinants of unplanned Pregnancy among Women: A case of Awach Health Centre IV in Gulu district.
Authors:   , Okae Norman , Kasozi Namagga Jane , Nambooze Grace
Published: June 2021

Background: Planning of pregnancy is a pertinent public health practice that every woman should embrace at her reproductive age. It is considered a major necessity in adopting a healthier lifestyle before pregnancy that leads to positive maternal-child health outcomes. On the contrary, unplanned pregnancy is ranked among the major public health problems that predispose women to huge mortality and morbidity mainly through criminal/unsafe abortion coupled with poor post-abortion care. Methodology: We used descriptive designs, employing qualitative approaches. We purposely selected 10 participants who lived within Aswa County, to participate in the study. Data were collected using an in-depth interview. Interpretive content analysis was used to generate categories and themes. Results:  The study generated four themes namely: individual determinants, family determinants, community determinants, and health facility determinants of an unplanned pregnancy. Conclusion and Recommendations :   This study has contributed substantially in revealing determinants of an unplanned pregnancy. In Awach Health Centre IV, the determinants of unplanned pregnancy are sexual desires, prostitution, school-going status, income level, number of sexual partners, amenorrhoea, marital status, contraceptives usage, religion, domestic violence, family planning discussion with husband. Others are; breastfeeding status during conception, the gender of existing children, recurrent obstetrical complications, distance from husband, rape, peer pressure, denial of pregnancy by men, type of settlement, contraceptive failure, and lack of sensitization. There is a need for a multi-level approach to address determinants of unplanned pregnancy ranging from individuals, families, communities, and health facilities approach. Improvement in the economic status of women, and implementing programs that encourage education of women/girl child could reduce unplanned pregnancy.

O artigo é fruto de uma investigação desenvolvida com o propósito de examinar os efeitos do discurso da tecnociência presentes na educação matemática praticada na disciplina de Matemática e nas disciplinas técnicas do curso Técnico em Agropecuária do IFRS-Sertão. Os aportes teóricos que dão sustentação a analítica empreendida no trabalho advêm, principalmente das noções de Michel Foucault e seus comentadores. O material de pesquisa foi produzido a partir de entrevistas com egressos do curso - da década de 1980 e da atualidade - documentos institucionais e materiais escolares (cadernos e avaliações da disciplina de Matemática dos dois momentos estudados. A análise desse material mostrou que: nas últimas três décadas, a lista de conteúdos da disciplina de Matemática não se alterou, a educação matemática da disciplina Matemática manteve sua abordagem abstrata e formal, e a educação matemática presente nas disciplinas técnicas alinhou-se com o discurso da tecnociência, incluindo recursos tecnológicos.
Divergent masculinities : a visual rhetoric study of masculinity on Tumblr
Authors:   , Nair Yoshen
Published: June 2021

This study is motivated by the need for visual communication designers or graphic designers to research changes in social identity that emerge on social media. Visual communication designers must deal with transforming and proliferating social identities in order to communicate effectively with their audiences. Social media are regarded in the study as highly influential on social identity changes. This study deals with divergent masculinities as an exemplar of these social identity changes, on the social media site Tumblr. To examine divergent masculinities, the study adopts a visual rhetoric perspective on Tumblr as one social media site of masculinity diversification. The literature review draws together social media perspectives with theoretical themes of reflexive social identity, gender, and fashion as the visual representation of masculinity. The resulting theoretical integration yields two guiding visual rhetoric concepts that inform inquiry into masculinity diversification on Tumblr: performativity and reflexivity. A Tumblr research setting is then demarcated by observing how the Social Network Site facilitates rhetor performativity of 'fashioned' masculine image posts, and audience reflexivity to these image posts. The roles of rhetor and audience are found to switch in the transaction of visual rhetoric, where image posts are audienced and further shared from one Tumblr user wall display to another. Meta-data on Tumblr makes extensive user activity around particular images evident, so that significant indications of diverging masculinities can be discerned. An analytical sampling strategy is then created by combining quantitative Tumblr meta-data with the theoretical themes of fashioned masculine performativity and reflexivity. This leveraged functional/theoretical analytical sampling strategy allows diversifying masculinities to be systematically identified. Five diverging masculinities are illustrated. These are regarded as exemplars of an ongoing process of masculinity diversification. It is suggested that the research design and methodology of the study can be used to investigate other forms of changing social identity besides masculinity. This is important for visual communication designers, who need to monitor changing social identity mores and their visual expression on social media.
Anaerobic co-digestion with industrial wastewater for biomethane production
Authors:   , Adedeji Jeremiah
Published: June 2021

The increasing demand for energy has led to the utilization of fossil fuels more abundantly as a quick alternative for generation of energy. The use of these sources of energy however as led to the generation of greenhouse gases which tend to cause climate change, thus affecting the ecosystem at large. Thus, there have been the search for alternative sources which cannot be depleted but do generate minimal greenhouse gases. One of such alternate sources is industrial wastewater which have shown to have high concentration of nutrients in the form of organic contents which can be converted by micro-organisms into energy, usually known as biogas, comprising majorly of CH4, CO2 and H2. Another important factor is that industrial wastewaters are a renewable energy source which are continuously generated due to increasing urbanisation and population growth. In this study, the characteristics of three agro-industrial based wastewaters used shows their potential for application in anaerobic co-digestion”. Anaerobic co-digestion method was utilized to harness the synergetic effect of both sewage sludge and agro-industrial wastewater as co-substrate for the generation of biomethane. The result of the effect of varying mix-ratio of the substrates on biomethane production of sugar wastewater and dairy wastewater indicated that mix-ratio of 1:1 for sewage sludge to sugar wastewater operated at 35oC was suitable for optimum generation of biomethane of 1400.99 mL CH4/g COD added and COD reduction of 54%. The model generated using design expert was found to navigate the design space and could perfectly predict the yield of biomethane effectively for the sugar wastewater mix. The biomethane potential tests (BMP) experiment using varying inoculum-substrate ratio (ISR) showed that operating at mesophilic temperature of 25oC with ISR of 1:2 and 2:1 for sugar wastewater and dairy wastewater respectively does increase the methane production within the first three (3) weeks. The kinetic models that best fit the anaerobic co-digestion for sugar wastewater was the first order model while the simplified Gompertz model favoured the dairy wastewater perfectly. The biomethane potential tests indicate significant increase the biomethane production and as well reduction in the volatile solid and chemical oxygen demand (COD) content. In conclusion, both sugar and dairy wastewater can be recommended as co-substrates for anaerobic digestion of sewage sludge for increased and improved biomethane production while simultaneously reducing their COD content at the same time.

The land is a limited resource. Due to the increase in population; it is necessary to increase crop yield from the viewpoint of food security. The sole use of inorganic fertilizers may create an imbalance in soil health by the reduction in crop yield. For sustainable crop production, it is necessary to balance the soil health using organics and bio-fertilizers along with the optimum use of chemical fertilizers. Bio-fertilizers are important in the nutrient management of crops because of their role in nutrient supply leading to reduce the use of chemical fertilizers. The use of Bio-fertilizers is a cost-effective and eco-friendly technology in crop production which is gaining importance in crop production the commonly used biofertilizers are azotobactor, azosprillium, PSB, VAM fungi.
CROP DIVERSIFICATION AND ITS RELEVANCE IN RISK MANAGEMENT IN THIRUVARUR DISTRICT OF TAMILNADU, INDIA
Authors: Shelton Peter Y. , Prabakar C.
Published: June 2021

Crop diversification at farm level is accepted to be an effective tool in risk mitigation in agriculture. But this concept of crop diversification is not been adopted much by farmers of Thiruvarur for reason unknown. Hence a study was undertaken to analyse the factors influencing the farmers awareness on the relevance of crop diversification in risk management and to rank the reason for non – adoption of crop diversification in Thiruvarur district of Tamilnadu. With regard to selection of study area, Thiruvarur district was considered as the universe of the study. The Mannargudi block of this district was purposively selected since it possesses cultivation area falling under both upstream irrigation as well as tail end irrigation. The Logit analysis revealed that the awareness on crop diversification had been positively and significantly influenced by education level of farmers, size of farm, no of agri – related meetings attended by respondents and labour scarcity. Further, Garrett ranking analysis revealed that the farmer’s attitude of “more reliance on traditional methodologies” was the prime reason for non - adoption of crop diversification in Thiruvarur district. Efforts may be enhanced by the institutional authorities to popularise the concept of crop diversification and its relevance in risk mitigation in agriculture. Village specific crop diversification models have to be identified considering the local features and advocated.

The current study involved collecting 225 samples of different age groups and from different clinical sources (burns and wounds). Selective and differential media, Microscopic Examination, Biochemical test, IMVIC tests, and Vitek 2 system were used to identify the bacterial species. The results showed that the bacterial isolates were distributed on Staphylococcus aureus, Pseudomonas aeruginosa, Staphylococcus epidermidis, Klebsiella pneumoniae, Escherichia coli and Proteus mirabilis. All isolates were multidrug-resistant to 12 antibiotics from different classes and according to the susceptibility test, isolate distinction in 2 groups (75 %) of MDR isolates were resistant to (5-9) antibiotics, while (25 %) were susceptible. Zinc Oxide nanoparticles synthesized was done by a green method with Zinc acetate dehydrate as a precursor and aqueous extract of Camellia sinensisas a reducing agent, color-changing to pale-white was an indication of the formation of ZnONPs. The average size and shape of the nanoparticles were detected by using Atomic Force Microscopy (AFM) which was 40 nm with a spherical shape. Scanning Electron Microscopy (SEM) showed the ZnO NPs have spherical, radial, and cylindrical structures. The wavelength range was measured by Ultraviolet-visible spectroscopy (UV-Vis) for monitoring the formation of the nanoparticles, which showed a sharp peak at 325 nm. The average crystallite size of ZnONPs was estimated using Debye Scherrer’s formula were 20-40nm by using X-ray Diffraction (XRD). Fourier-transform infrared spectroscopy (FT-IR) spectra have been used for ZnONPs to detect the functional groups found in the synthesis process via green tea extract. Keyword: ZnO NPs.

Cooking times of fourteen Egyptian and introduced cowpea genotypes were evaluated under different cooking conditions. Soaking treatments manifested shorter time than unsoaked treatments. Adding sodium bicarbonate or baking powder to soaking and cooking solutions gave more shorter cooking time. Microwaves treatment gave the shortest cooking time than all other treatments and conserved as a new approach. All studied cowpea genotypes and all cooking treatments exhibited significant variations. The blacked colored seeds needed shorter cooking time than the red seeds, while round or small seeds needed longer time to complete cooking. The observed significant differences among the genotypes were reflected to genotypic and phenotypic variations and consequently to high broad sense heritability estimates and to high values of genetic advances. Such estimates suggested the ability to achieve possible improvement in cooking time of cowpea seeds which might eventually reflect on their cooking quality.

Published: June 2021

Heavy metal pollution is a global issue of concern which results from both biogenic and anthropogenic activities. Hence, an investigation of soil pollution is pertinent because of its potential threat to human health. The present study examined the concentrations, contamination and pollution load index cum ecological risk factor for some heavy metals in soil samples collected from Borno Express (BOEXP), Tashan Kano (TASKP) and Tashan Bama (TASBP) motor parks within Maiduguri, Borno state of Nigeria. The data obtained showed mean concentration range of 0.34 - 1.18 mg/kg, 0.04 - 0.15 mg/kg, 0.07 - 0.41 and 0.18 - 0.29 mg/kg for Zn, Cr, Cd and Cu respectively. Nonetheless, lead was not detected in any and all samples analyzed. The increasing order of concentrations in the soils followed: Zn > Cu > Cr > Cd, Cu > Cd > Zn > Cr and Cd > Zn > Cu > Cr for BOEXP, TASKP and TASBP motor parks respectively. Notwithstanding, the results showed lower concentrations to the allowable limits of World Health Organization (WHO). Furthermore, the contamination factor of cadmium in the TASKP fell within the (0.10 – 0.25) category, indicative of slight contamination whereas in TASBP, the calculated value 0.5125 was within (0.51 -0.75) category implying severe contamination. The other heavy metals analyzed showed contamination factor as well as pollution index values < 0.1 indicative of very slight contamination.Keywords: Borno Express, Tashan Kano, Tashan Bama, Motor Parks, Contamination Index.
Abordagem de via aérea difícil em paciente com Síndrome Orofaciodigital tipo II ou Síndrome de Mohr: um relato de caso

Published: June 2021

A síndrome orofaciodigital é um transtorno raro do desenvolvimento embrionário. Os pacientes podem apresentar alterações de boca, face, mãos e pés. Há descrito pelo menos 11 formas clínicas diferentes da síndrome, entre elas a síndrome orofaciodigital tipo II ou síndrome de Mohr. A abordagem de via aérea na síndrome orofaciodigital pode ser um desafio, já que as alterações craniofaciais como lábio leporino/fenda palatina, presentes na síndrome, são preditores de via aérea difícil em pediatria. O relato de caso descreve uma lactente de 4 meses, portadora de Síndrome de Mohr que foi admitida com sintomas respiratórios e, durante internação, apresentou parada cardiorrespiratória, sendo realizada laringoscopia direta por diversas vezes, sem sucesso na intubação orotraqueal. As diferenças anatômicas explicam o potencial maior de dificuldades técnicas das vias aéreas em lactentes do que em adolescentes ou adultos. Em geral, as vias aéreas dos lactentes diferem das de adultos por cinco pontos: 1) tamanho relativamente grande da língua da criança em relação à orofaringe; 2) a laringe tem localização mais cefálica no pescoço; 3) a epiglote é curta, em forma de ômega e angulada sobre a entrada da laringe; 4) as cordas vocais são anguladas, consequentemente, um tubo traqueal que passou cegamente pode facilmente se alojar na comissura anterior em vez de deslizar para dentro da traqueia; 5) a laringe é em forma de funil, sendo a porção mais estreita localizada na cartilagem cricoide. Os guidelines de via aérea difícil em pediatria são ferramentas essenciais, nesse contexto, para prevenção de complicações associadas sendo assim imprescindível o domínio destes por profissionais intensivistas e anestesiologistas. O compartilhamento dessas informações se torna importante já que há poucos dados na literatura sobre abordagem de via aérea em paciente com Síndrome de Mohr.

Published: June 2021

Abstract. Peatlands are one of the largest terrestrial carbon sinks on the planet, yet little is known about carbon accumulation rates (CARs) of mountainous examples. The long-term variability in the size of the associated carbon sink and its drivers remain largely unconstrained, especially when long-term anthropogenic impact is also considered. Here we present a composite CAR record of nine peatlands from central-eastern Europe (Romania and Serbia) detailing variability in rates of carbon accumulation across the Holocene. We show examples of extremely high long-term rates of carbon accumulation (LORCA > 120 g C m−2 yr−1), indicating that at times, mountain peatlands constitute an efficient regional carbon sink. By comparing our data to modelled palaeoclimatic indices and to measures of anthropogenic impact we disentangle the drivers of peat carbon accumulation in the area. Variability in early and mid-Holocene CARs is linked to hydroclimatic controls, with high CARs occurring during the early Holocene and lower CARs associated with the transition to cooler and moister mid-Holocene conditions. By contrast, after 4000 years (calibrated) before present (yr BP) the trends in CARs indicate a divergence from hydroclimate proxies, indicating that other processes became the dominant drivers of peat CARs. We suggest that enhanced erosion following tree cover reduction as well as enhanced rates of long-distance atmospheric dust fallout might have played a role as both processes would result in enhanced mineral and nutrient supply to bog surfaces, stimulating peat land productivity. Surprisingly though, for the last 1000 years, reconstructed temperature is significantly correlated with CARs, with rising temperatures linked to higher CARs. We suggest under future climate conditions, predicted to be warmer in the region, peat growth may expand, but that this is entirely dependent upon the scale of human impact directly affecting the sensitive hydrological budget of these peatlands.
Multiscale assessment of TRMM (3B42 V7) and GPM (IMERG V5) satellite precipitation products over a Mediterranean mountainous watershed with sparse rain gauges in the Moroccan High Atlas (case study of Zat basin)

Published: June 2021

Abstract. The performance of Tropical Precipitation Measurement Mission (TRMM) and its successor, Global Precipitation Measurement (GPM), has provided hydrologists with a source of critical precipitation data for hydrological applications in basins where ground-based observations of precipitation are sparse, or spatially undistributed. The very high temporal and spatial resolution satellite precipitation products have therefore become a reliable alternative that researchers are increasingly using in various hydro-meteorological and hydro-climatological applications. This study aims to evaluate statistically and hydrologically the TRMM (3B42 V7) and GPM (IMERG V5) satellite precipitations products (SPPs), at multiple temporal scales from 2010 to 2017, in a mountainous watershed characterized by the Mediterranean climate. The results show that TRMM (3B42 V7) and GPM (IMERG V5) satellite precipitation products have a significant capacity for detecting precipitation at different time steps. However, the statistical analysis of SPPs against ground observation shows good results for both statistical metrics and contingency statistics with notable values (CC > 0.8), and representative values relatively close to 0 for the probability of detection (POD), critical success index (CSI), and false alarm ratio (FAR). Moreover, the sorting of the events implemented on the hydrological model was performed seasonally, at daily time steps. The calibrated episodes showed very good results with Nash values ranging from 53.2 % to 95.5 %. Nevertheless, the (IMERG V5) product detects more efficiently precipitation events at short time steps (daily), while (3B42 V7) has a strong ability to detect precipitation events at large time steps (monthly and yearly). Furthermore, the modeling results illustrate that both satellite precipitation products tend to underestimate precipitation during wet seasons and overestimate them during dry seasons, while they have a better spatial distribution of precipitation measurements performance, which shows the importance of their use for basin modeling and potentially for flood forecasting in Mediterranean catchment areas.
Global component analysis of errors in three satellite-only global precipitation estimates

Published: June 2021

Abstract. Revealing the error components of satellite-only precipitation products (SPPs) can help algorithm developers and end-users understand their error features and improve retrieval algorithms. Here, two error decomposition schemes are employed to explore the error components of the IMERG-Late, GSMaP-MVK, and PERSIANN-CCS SPPs over different seasons, rainfall intensities, and topography classes. Global maps of the total bias (total mean squared error) and its three (two) independent components are depicted for the first time. The evaluation results for similar regions are discussed, and it is found that the evaluation results for one region cannot be extended to another similar region. Hit and/or false biases are the major components of the total bias in most overland regions globally. The systematic error contributes less than 20 % of the total error in most areas. Large systematic errors are primarily due to missed precipitation. It is found that the SPPs show different topographic patterns in terms of systematic and random errors. Notably, among the SPPs, GSMaP-MVK shows the strongest topographic dependency of the four bias scores. A novel metric, namely the normalized error component (NEC), is proposed as a means to isolate the impact of topography on the systematic and random errors. Potential methods of improving satellite precipitation retrievals and error adjustment models are discussed.
Distribution of suspended particulate matter at the equatorial transect in the Atlantic Ocean
Authors: Sivkov Vadim , Bubnova Ekaterina
Published: June 2021

Abstract. Studied oceanographic transect across the Equatorial Atlantic is considered as a “screenshot” of suspended particulate matter distribution against a hydrographical background. The area of abnormal high suspended matter volume concentrations was found above the Sierra Leone Rise from top to bottom (eastern part of the transect). The suggested explanation for the anomaly is based on the ballast hypothesis whereby solid particles are incorporated as ballast into suspended biogenic aggregates, leading to increased velocities of sinking. This process is located within the Northwest African upwelling area since the plankton exposed to the Saharan dust abundance form a significant number of aggregates lately transported equatorward via Canary Current. The intermediate nepheloid layer associated with the Deep Western Boundary Current was recorded from the American Slope at the 3200–3700 m to the depth of 4300 m above the Para Abyssal Plain. Antarctic Bottom Water enriched in the suspended matter was found mostly in the troughs at 40–41° W. It was detached from the bottom, coinciding with the core of the flow due to the bottom rise (“dam”) located up-stream. The grain size of particles was in accordance with polymodal distribution – the 2–4 μm and the 8–13 μm modes. The registered rise in the percentage of the 7–21 μm-sized particles suggests the presence of the well-known coarse mode (20–60 μm) formed by aggregation of transparent exopolymer particles (mucus).

Esta metapesquisa objetivou identificar a perspectiva epistemológica explicitada em 56 dissertações da Linha 1 – “Políticas Educacionais, História e Organização da Educação”, do Programa de Pós-Graduação em Educação da Universidade Estadual do Centro-Oeste (PPGE/Unicentro), formuladas no período de 2014 a 2018, a partir dos conceitos de teorização combinada e teorização adicionada (MCLENNAN, 1996) e da proposta de metapesquisa em política educacional, por meio da leitura sistemática da amostra selecionada (MAINARDES, 2017, 2018a, 2021). Sobre os resultados deste estudo, destaca-se que 51 mestrandos (91,04%) indicaram autores ou tradições/matrizes teóricas, não fazendo referência às perspectivas epistemológicas utilizadas nas dissertações. As demais cinco dissertações (8,96%) não realizaram tais apontamentos; desse modo, englobaram diferentes autores que fundamentaram as análises realizadas. Diante do exposto, quatro desses trabalhos (7,18%) foram classificados em teorização combinada, pois realizaram junção de autores que fundamentaram um referencial consistente para a análise. Uma dissertação (1,78%) realizou pouca análise teórica, o que culminou em uma pesquisa classificada como teorização adicionada. A explicitação do materialismo histórico-dialético destacou-se como perspectiva teórica mais utilizada nas pesquisas analisadas, um total de 35 dissertações (62,5%). Assim, verificou-se que as pesquisas formuladas no âmbito do PPGE/Unicentro, embora mencionem as perspectivas teóricas utilizadas, poderiam ser classificadas como estudos de teorização combinada ou teorização adicionada, pois fizeram uso de diversos autores e diversas teorias para formulação do referencial teórico.

INTRODUCTION: In addition to traditional risk factors for falls (e.g., reduced muscle strength, polypharmacy, and poor vision), researchers have been investigating whether other factors, such as near-falls, can be identified to allow early intervention and prevention. A near-fall can be defined as a slip, trip, or loss of balance that would result in a fall if adequate recovery mechanisms were not activated. Despite the increasing interest in near-falls, there is no consensus about the definition, reporting methods, and contributing factors. OBJECTIVE: To identify how near-falls among older adults have been defined, reported, and monitored in the scientific literature. METHODS: Indexed literature published in English, Spanish, and Portuguese will be considered and retrieved from 10 databases, until August 31st, 2020. Two authors will independently screen titles, abstracts, and full texts against the eligibility criteria, and disagreements will be resolved by a third reviewer. This review will consider studies with different designs that have included older adults (aged 60 years and over), recruited participants from different settings, and had an explicit definition and/or reporting of near-falls. A customized form will be used to extract data from the included studies. The results will be presented in tabular form, accompanied by a narrative summary. This protocol is registered at https://osf.io/txnv4. EXPECTED RESULTS AND RELEVANCE: Depending on the results, a conceptual framework for near-fall reporting, contributing factors, and a possible prodrome of falls will also be presented. It is expected that the present study will help professionals identify and manage near-falls in different settings.

الملخص

يُشكّل التلوّث البيئي الناتج من الأنشطة الصناعية والمنزلية والزراعية ضغطًا كبيرًا على الموارد المائية على مستوى العالم؛ ذلك أنّ للمياه المستعملة تأثيرًا مباشرًا في البيئة، إذ يتم تصريفها مباشرة في الطبيعة بعد إخضاعها للمعالجة وفق معايير محدّدة، فتحتوي بذلك على مجموعة كبيرة ومتنوعة من الكائنات الحية الدقيقة والمركبات العضوية وغير العضوية التي تسبب العديد من الأمراض والمخاطر. وفي هذا الإطار، جمع الباحثون عينات من مياه البحر ومن مياه الصرف الصحي المعالجة وغير المعالجة من أربعة بلدان في جنوب البحر الأبيض المتوسط، هي: مصر والمغرب والجزائر وتونس. خضعت هذه العيّنات لمجموعة من التحاليل الفيزيائية-الكيميائية والميكروبية، ثمّ تمّت مقارنة النتائج المتحصّل عليها بدراسة أُجريت في الفترة نفسها بدولة في شمال البحر الأبيض المتوسط، وهي إيطاليا. أظهرت الدراسات الفيزيائية-الكيميائية تلوثًا بارزًا لمياه الصرف ومياه البحر التي تم جمعها وتحليلها من البلدان العربية الأربعة وإيطاليا، حيث أثبتت وجود الملوثات: الأكسجين الكيميائي (COD) والطلب على الأكسجين البيولوجي (BOD5) و(TOC)، والنترات (NO3) وغيرها، وأيضًا بعض المعادن الثقيلة. من ناحية أخرى، سمحت تقنية (DGGE) بتقييم مباشر للتنوع البكتيري الموجود بهذه المياه المستعملة وكذلك مياه البحر، وقد أثبتت هذه التحاليل شدة التنوع البكتيري في هذه المياه.
Does the Quality of Institutions Matter for Financial Inclusion? Cross Country Evidence
Authors: Muriu Peter W.
Published: June 2021

Despite evidence on the importance of financial inclusion, little is known about the role of institutions in fostering inclusion partly because of data availability. Using annual data corresponding to 120 countries for the period 2004-2019, this study investigates country institutional characteristics associated with the ownership of deposit accounts. A standard regression model is estimated using fixed effects panel data techniques along with financial inclusion proxy and three measures of institutional quality. This paper provides the first empirical justification that financial inclusion is non-negligibly driven by the institutional context. Specifically, rule of law and quality of regulations are crucial in enhancing financial inclusiveness, more so in Africa where they have a stronger effect relative to other regions. Banks and depositors in Africa may be operating in an environment characterized by weak legal systems and excessive or challenging regulations. The evidence presented in this paper may therefore help with the sequencing of institutional reforms that could promote financial inclusion.

Published: June 2021

Se identifican las concepciones sobre la enseñanza y el aprendizaje de 80 maestros de primaria, mexicanos, y se estudian las relaciones que se establecen entre estas concepciones y sus prácticas educativas en clases de ciencias. Para estudiar las concepciones de los maestros se aplicó una entrevista de administración individual. Para estudiar las prácticas educativas se realizaron registros observacionales de las lecciones de los maestros. Un análisis cualitativo de las respuestas de los maestros a la entrevista reveló tres concepciones de la enseñanza y el aprendizaje: tradicional, de transición entre una perspectiva tradicional y una constructivista y constructivista. El análisis de las relaciones entre las concepciones de la enseñanza y el aprendizaje y las prácticas educativas mostró incongruencias. La mayoría de los maestros sostuvieron concepciones sobre la enseñanza y el aprendizaje más innovadoras que lo que realmente hicieron en el aula.

Una visión alternativa de la evaluación por pares : perspectivas dialógicas
Authors: Tobin Kenneth
Published: June 2021

Presento un enfoque alternativo a la evaluación por pares y la participación para publicar en una revista internacional. Los coeditores deciden si los artículos son adecuados para ser publicados, los evaluadores son seleccionados por su área de especialización y su posición en dicha área, además se busca que estos evaluadores aporten diferentes perspectivas, mientras que los foros públicos permiten que la evaluación por pares sea visible para los lectores de la revista. El proceso de evaluación toma el papel central en un proceso dialógico donde los puntos de acuerdo y desacuerdo son identificados y entendidos como progreso en el campo de la educación científica y matemática.
Relaciones CTS en la educación científica básica. II. Investigando los problemas del mundo
Authors: García-Carmona Antonio
Published: June 2021

Se presenta una propuesta educativa orientada a desarrollar parte del currículo de ciencias, de 4o de ESO (15-16 años), a través del análisis de algunos problemas del mundo actual. Su diseño parte de las siguientes hipótesis: 1) resultan familiares y accesibles para los alumnos, lo que estimula su interés hacia ellos; 2) tienen un carácter multidisciplinar, que permite integrar diferentes contenidos en un mismo contexto; 3) permiten valorar las interacciones Ciencia-Tecnología-Sociedad (CTS), a fin de favorecer una percepción realista y adecuada de los mismos; 4) favorecen el pensamiento crítico y responsable de los alumnos; y 5) son ideales para plantear una enseñanza de la ciencia problematizada. Se describen las fases en las que se desarrolló en el aula, los instrumentos empleados para su evaluación, y los resultados más relevantes del estudio. La evaluación (cualitativa) de la propuesta indica que planteando la educación cientí!ca desde tal perspectiva, se contribuye al desarrollo de las competencias básicas demandadas por el nuevo marco educativo europeo.
Propuesta de enseñanza en cursos introductorios de física en la universidad, basada en la investigación didáctica : siete años de experiencia y resultados
Authors: Guisasola Aranzabal Jenaro , Zubimendi José Luis , Almudí García José Manuel , Ceberio Mikel
Published: June 2021

El objetivo de este trabajo es presentar los resultados de una innovación educativa en primer curso de física basada en un modelo de enseñanza como investigación orientada. Este modelo ha sido presentado en diferentes trabajos anteriores y se articula en la idea de que el aprendizaje y la enseñanza de las ciencias pueden desarrollarse como un proceso de (re)construcción de conocimientos en un contexto inspirado en el propio de la investigación científica y guiado por el profesorado. La propuesta se ha llevado a cabo en dos escuelas de ingeniería de la Universidad del País Vasco. Se presentan los resultados conseguidos durante varios años y se comparan con los obtenidos en la enseñanza habitual de las mismas escuelas. La innovación realizada aporta evidencias de que una enseñanza que engloba los aspectos conceptuales, procedimentales y actitudinales hace posible obtener resultados mejores en el aprendizaje de la física en primer curso de universidad.
La calidad científica del contenido sobre el tema de la estructura de la materia en textos universitarios de química general
Authors: Malaver Manuel , Pujol Rafael , D'Alessandro Martínez Antonio
Published: June 2021

En este trabajo se estudian algunos conceptos e ideas científicas sobre el tema de la estructura de la materia en los textos de química más usados en los cursos básicos universitarios en Venezuela, usando técnicas de análisis de contenido. Se encuentra que los textos analizados presentan algunos casos de explicaciones y conceptos con un alto grado de inexactitud e imprecisión y un uso inapropiado de los niveles macroscópico y microscópico, lo que podría generar concepciones erróneas en el estudiante.
