Published: July 2023

Abstract

Background

Acute appendicitis is one of the most common causes of acute abdomen. In case of delay in the diagnosis process, perforation develops, and the patient's morbidity and mortality increase. In our study, we evaluated the effectiveness of laboratory, radiological, and physical examination findings in diagnosing acute appendicitis.

Methods

A total of 488 patients hospitalized with a prediagnosis of acute appendicitis were included in the study. 162 patients constituted the unoperated and 326 patients constituted the operated group (Groups 1 and 2). The two groups were compared in terms of age, gender, and ultrasonographic findings, as well as Alvarado score parameters.

Results

In logistic regression analysis, which included only Alvarado parameters, anorexia was the most valuable parameter in predicting surgery (p=0.000). The Alvarado score was found to be the most useful parameter in making the surgery decision (p

Published: July 2023

Amaç: Organ naklinde; beyin ölümü tanısı aşamasından nakil ameliyatı ve sonrası tüm süreçlerde olaya primer müdahil olan ve organ bağışı konusunda topluma ön ayak olması gereken hekimlerin otopsi eğitimi sonrası bu konuya bakış açılarındaki değişimin araştırılması amaçlanmıştır.

Gereç ve Yöntem: Manisa Celal Bayar Üniversitesi Tıp Fakültesi’nde eğitim gören dönem 5 öğrencilerine adli tıp stajı içerisinde otopsi eğitimi öncesinde ve sonrasında organ bağışına karşı tutumlar ölçeği anketi uygulanmış ve görüşlerinde meydana gelen değişiklikler araştırılmıştır.

Bulgular: Çalışmamıza 250 öğrenci katılmış olup, yaş ortalamalarının 23.15 bulunduğu, organ naklinin genel itibariyle desteklendiği, önemli olduğunun düşünüldüğü, kadın öğrencilerin erkek öğrencilere göre organ bağışına daha pozitif bir yaklaşım gösterdikleri, öğrencilerde beklenildiği gibi adli otopsi eğitiminden sonra organ bağışına karşı olumlu tutumlarda anlamlı artış olduğu görülmüştür.

Sonuç: Kadavradan nakil konusunda yaşanan çekimserlik hali ülkemizde organ bağışının istenilen düzeyin altında kalmasına neden olmaktadır. Otopsi eğitimi süresince postmortem organlarda meydana gelen değişiklikleri ilk elden gözlemleme şanslarının bulunması öğrencilerin organ bağışında olumlu değişikliğe neden olmuştur. Organ bağışı sayısını arttırmak için sosyal kampanyalar ve bilgilendirmeler yapılarak bu önemli konu gündemde tutulmalıdır.
Pureza da raça, sanidade do corpo e educação escolar
Authors: Gonçalves Rozemy Magda Vieira , Saraiva Karla , Gonzalez Deborah Barbosa
Published: July 2023

Este artigo objetiva analisar a articulação da eugenia e da higiene com a educação escolar. O material empírico foi a Revista Brasileira de Estudos Pedagógicos (RBEP), publicada desde 1944, complementado com publicações em periódicos da área da saúde. As análises foram desenvolvidas a partir de uma metodologia desenvolvida por Saraiva (2013) para pesquisas documentais. Observou-se que a eugenia esteve presente em artigos publicados entre 1944 e 1947, predominando a vertente relacionada com o higienismo racial, enquanto artigos tratando do ensino de higiene aparecem na RBEP até os anos 1960. Entretanto, o tema não é excluído das escolas, permanecendo, inclusive, em documentos legais. Desde o final do século XX, a educação higiênica aparece em periódicos da área da saúde, sinalizando que deixa de ser um tema a cargo da educação. Ele é mobilizado em projetos realizados em escolas públicas, sugerindo que permanece a associação entre pobreza e falta de higiene, que embasava o higienismo racial dos primeiros artigos da RBEP.

O artigo é um recorte da tese de doutorado em educação e traz como temática central a mediação no ensino da escrita, revisão e reescrita, com professores em formação inicial participantes do Programa Residência Pedagógica (PRP), no curso de Letras de uma Instituição de Ensino Superior do estado de Rondônia (RO). A partir dessa temática, estabelecemos as teses de pesquisa: i) a mediação, tanto interna quanto externa (VYGOTSKY, 1991; 2020), contribui para a apropriação de conhecimento pelo educando e ii) o PRP auxilia no desenvolvimento da prática docente por meio da relação teórico-prática de forma crítica e reflexiva por parte dos envolvidos. Com base nisso, objetivamos apresentar as contribuições da mediação docente no desenvolvimento teórico-prático do processo de escrita, revisão e reescrita com acadêmicos do curso de Letras residentes do PRP. Utilizamos a Teoria Histórico-Cultural, a Análise de Conteúdo e as orientações da escrita como processo, discutidas pelo Interacionismo linguístico. Optamos por utilizar a pesquisa-ação (TRIPP, 2005; THIOLLENT, 2011) com vistas a intervir na realidade pesquisada.  Para coleta de dados utilizamos questionário e observações das práticas docentes dos participantes. Os resultados demonstram que os residentes receberam conhecimentos teóricos sobre o processo de escrita através da mediação (interna e externa) e conseguiram se apropriar dos conhecimentos obtidos no curso de formação para desenvolver práticas satisfatórias de escrita, revisão e reescrita de textos junto ao seus alunos no PRP. Concluímos que a mediação é um processo educacional importante para ser desenvolvido nos cursos de formação inicial docente.

Purification of biodiesel with dry adsorbents is an alternative method, as it uses compounds that eliminate the need for water in the process without generating liquid effluent. Currently, there is little discussion about the reuse of different types of adsorbents and in this context, the present work presents an efficient method of purification and investigates the performance of the reuse of Magnesol® in the purification of biodiesel in order to generate less waste to the environment. Therefore, the Magnesol® used was washed with several solvents with different polarity characteristics. Among the solvents tested, THF is the best solvent for the purification of Magnesol® and, after optimizing the Magnesol® purification process, it was concluded the best conditions are three washes in solvent / adsorbent ratio 30:1 at room temperature, resulting in only 3.89% of the residual value of contaminants and being an alternative for biodiesel companies.
Biodegradation and biotransformation of petroleum hydrocarbons: progress, prospects, and challenges
Authors: Felisardo Raul José Alves , Gonçalves Amanda de Azevedo
Published: July 2023

Oil is considered the main source of energy, being essential for the realization of various industrial activities. However, it is detrimental to the environment, since in addition to the release of polluting gases during combustion, its exploitation involves risks of water contamination, through leaks. Petroleum hydrocarbon pollutants are part of the recalcitrant compounds and their elimination from the environment causes enormous ecological impacts. The restoration of these environments is not a trivial challenge, as natural degradation, without anthropogenic involvement, depends on the nature, composition, physical and chemical properties of these compounds. Thus, bioremediation appears as alternative in the biodegradation process through the addition of microorganisms, nutrients or other substances that cause and accelerate decontamination. The advantages of these methods involve efficiency and low cost, when compared to other technologies. This work gathers knowledge about the perspectives of application of bioremediation systems in the recovery of environments polluted by petroleum hydrocarbons, discussing progress, perspectives and challenges.

Published: July 2023

Analyze the implications of the configuration of the Sectors that make up the Water Supply Systems (WSSs) in the municipality of Belém, capital of the state of Pará, on their economic sustainability. The research was developed in three stages. The first stage consisted of identifying and collecting information regarding the WSSs operated by Companhia de Saneamento do Pará – COSANPA. In the second stage, operational and commercial indicators were determined for both Sectors selected as the most suitable for comparison, in this case the 12th Sector and the 23rd Sector. In the last stage, an analysis of the economic sustainability of selected Sectors was performed. It was verified that 04 of the 39 WSSs collect raw water from a surface water source, while the other 35 WSSs use deep wells (about 270 meters deep) to collect water from Pirabas artesian aquifer. In addition, operational efficiency indicators were calculated, such as the “Distribution Losses Index” – 69,08% (12th Sector) and 72,67% (23rd Sector), and economic sustainability indicators, such as the “Total Expense with the Services per Billed Cubic Meter” – R$1,92/m³ (12th Sector) and R$1,29/m³ (23rd Sector). In conclusion, due to the classification of both studied Sectors, regarding operational efficiency and economic sustainability, as inefficient and partially sustainable respectively, it is recommended to improve the operational and comercial management of the regional concessionaire, in compliance with the premises of Law No. 14.026/2020 and to ensure the economic and financial balance of the service provider.

Amores possíveis?
Authors: Dadico Luciana
Published: July 2023

Este ensaio traz uma discussão sobre as relações amorosas sob a perspectiva da Teoria Crítica da Sociedade. Partindo da crítica freudiana à promessa de felicidade embutida em uma certa ideia de amor, e da associação romântica entre o sentimento amoroso e as paixões políticas, discuto as implicações mútuas do tema em âmbito público e privado. Busco refletir sobre a potência do amor para impulsionar transformações sociais, ao mesmo tempo em que considero as assimetrias que estruturam as relações privadas em sentido político. Para T.W. Adorno, o amor não é um sentimento espontâneo, mas mediado cultural e socialmente, e atravessado por contradições. No contexto de uma vida lesada, contraposta aos ideais de uma vida boa, discuto o amor como exercício de resistência, bem como as lacunas presentes em análises que desconsideram as assimetrias de poder que persistem como empecilho à condição de não violência das relações sociais.
Pruebas rutinarias para el virus de inmunodeficiencia humana, y su relación con el diagnóstico clínico oportuno
Authors: Aguirre Realpe Karla , Sánchez Mabel
Published: July 2023

Desde hace más de treinta años, cuando se desarrollaron las primeras pruebas de laboratorio capaces de detectar la infección por el Virus de la Inmunodeficiencia Humana (VIH). Los avances tecnológicos han permitido la creación de diversas pruebas cada vez más precisas y sensibles. Es crucial que los profesionales médicos interpreten correctamente los resultados de estas pruebas en su práctica diaria para garantizar un manejo terapéutico adecuado de los pacientes. El objetivo de esta investigación fue describir según la evidencia científica la sensibilidad, especificidad e indicaciones de pruebas para la detección del virus de la inmunodeficiencia humana y su relación con el diagnóstico oportuno. Se realizó una revisión bibliográfica cualitativa, retrospectiva y documental, enfocada en el análisis de la literatura científica relevante a la temática abordada. Se aplicó el método PRISMA para recopilar, analizar y sintetizar la información más pertinente que contribuyó al desarrollo de la investigación, y se empleó el juicio crítico para verificar la información utilizada. La implementación de las directrices para el cribado de VIH en la normativa local ha llevado a una mayor preferencia por las pruebas rápidas de antígeno o anticuerpo, lo que ha mejorado la eficiencia y efectividad del proceso de detección del VIH. Las pruebas rápidas son la más utilizada en el cribado debido a su alta confianza y sensibilidad, arrojando un resultado de sensibilidad del 100% y una especificidad del 99.69%. Abordar las desigualdades socioeconómicas y educativas es crucial para mejorar la detección temprana del VIH en la población.

Las leishmaniasis son enfermedades zoonóticas y de transmisión vectorial, su complejo biológico comprende diferentes especies de parásitos, tanto reservorios como vectores, que causan en el humano un conjunto de síndromes clínicos que comprometen la piel, como leishmaniasis cutánea o leishmaniasis mucocutánea, además hay otra forma de presentación sistémica conocida como leishmaniasis visceral. La transmisión ocurre cuando un flebótomo hembra infectado con el parásito (Leishmania spp.), pica a un huésped potencial. Su presencia está vinculada a la pobreza, factores sociales, ambientales y climáticos, esto influye en su epidemiología. El presente estudio tuvo como objetivo determinar la sensibilidad y especificidad de las técnicas de laboratorio para el diagnóstico de leishmaniasis. Para ello, se realizó una investigación de diseño documental con búsqueda exhaustiva en diferentes bases de datos, empleando artículos científicos en español e inglés, aplicando criterios de inclusión y exclusión, seleccionando un total de 39 artículos sistemáticamente revisados. En relación a los resultados se demuestra que, para cada presentación clínica de leishmaniasis, existen varios métodos como los parasitológicos, serológicos y moleculares que son muy sensibles y específicos, pero se debe seleccionar una muestra adecuada, que proporcionaran resultados rápidos y eficientes, para que el paciente reciba un tratamiento oportuno. La microscopía tiene una sensibilidad variable, pero es considerada el “Estándar de oro” y depende de la experticia del analista, las pruebas serológicas son más utilizadas para leishmaniasis visceral, en cuanto a la sensibilidad y especificada de los métodos moleculares son excelentes, pero requieren de personal capacitado, reactivos, equipos costosos y un área especial.

Education programs for young people in the fields of architectural formatting, heritage, urban and spatial planning
Authors: Danilović-Hristić Nataša , Nenković-Riznić Marina , Simonović-Alfirević Sanja
Published: July 2023

In professional circles, it often seems that the state of our urban environment and attitude towards the natural environment reflect a lack of attention devoted to educating all generations, and a lack of awareness raised on this topic. The picture of our settlements is actually a picture of ourselves. For this reason, and the desire to draw young people in and explain professional topics to them in an adequate and acceptable way, and to develop a love of the environment and awareness of the quality of life, several institutions and organizations have launched independent education programs. These programs and workshops are implemented partly voluntarily, or within activities related to specific events and projects and the regular activities of individual institutions, and they are designed as a supplement to educational programs in preschools, schools and universities. The paper analyzes known approaches, methods and techniques related to youth participation, shown through a selected review of the literature. Also cited are examples of several different educational workshops in some of Belgrade's professional institutions and organizations, based on architectural formatting, urban planning, the protection of built heritage and the preservation of ecological corridors. Based on the experiences acquired and the observed results, a series of recommendations are formed for the organization and implementation of this form of education. The aim of the research is to highlight the importance, possibilities and benefits of educating young people in terms of understanding and caring for the space that surrounds us, as well as others with whom we share that space. Participation in the creative process contributes to gathering observations, ideas, visions and expressing needs, with the possibility of their application.
Architect Janko Šafarik and his Belgrade opus (1911-1932)
Authors: Banković Angelina
Published: July 2023

The subject of the research presented in this paper is the Belgrade opus of architect Janko Šafarik (1882-1949). The research is mainly based on primary sources preserved in the Historical Archives of Belgrade, the Belgrade City Museum, the Military Archives and the archives of the Technical University in Dresden. Although Šafarik and his architectural opus have not been completely presented in any previously published papers, a number of them contain important data related to his work, which is why they were considered in this research. The architect's biographical information is presented, followed by his Belgrade opus, which is chronologically divided into before and after World War One. Most attention is devoted to the most fruitful period of his activity, the 1930s. That is when Šafarik worked in the Technical Bureau - the Fenix Company, within which most of his projects were created. All projects attributed to Šafarik, confirmed by considering available archival material, are presented in this paper, regardless of whether they were carried out or not. Through their analysis, the conclusion was reached that Šafarik did not belong to a group of architects who were looking for their own unique architectural expression, or to those who were dominantly committed to one style, but rather that in his oeuvre, his approache varied, mostly in accordance with the dominant approach at the time each individual project was created.

Authors: Basarić Jelena
Published: July 2023

The Lower Danube Basin boasts rich and quite diverse cultural heritage, which can be pivotal for the development of tourism and an important factor with regard to social and economic changes in Eastern Serbia. As a result of cultural heritage, numerous European and world capitals have invested effort in developing destinations and sites that promote cultural content and attractions. Cultural values and traits from different historical periods attract more and more tourists, thus increasing interest in cultural tourism. Cultural heritage adds value to the basic tourist content, greatly contributing to increased tourist traffic and the promotion of local communities, but also to the further development and improvement of tourist offers. When it comes to cultural tourism in the Lower Danube Basin, it must be stressed that there is no individual or common tourism development strategy in this area. This paper is aimed at presenting historical heritage as cultural potential for tourist valorisation, impacting the local, regional and national environment. Cultural heritage can play a decisive role in creating a cultural and tourist development policy in the area of the Lower Danube Basin, having in mind the method of managing cultural values and possibilities in order to harmonise them with other kinds of tourism. The purpose of this paper is to highlight the potential of cultural heritage, which would contribute to shaping the cultural and tourist identity of this area in both local and international tourist markets.

Published: July 2023

The aim of the research in this paper is to consider the state and basic trends of vegetable production in the Republic of Serbia for the period from 2012. to 2020. Therefore, the paper indicates which necessary measures should be taken to increase the volume of vegetable crop production in our country and improve the production. In spite of all problems, and owing to significant but insufficiently used local resources (people) and favourable natural conditions (climate features, soil and water resources), vegetable production in the Republic of Serbia has a good opportunity for intensive development. This development has to be accompanied by the appropriate credit and monetary support, investment and incentives.

Published: July 2023

The purpose of this article is to analyse the trend of global gold price yields and volatility with the aim of making effective financial decisions about investments in this precious metal, by applying and comparing the results of ARCH and GARCH competing models, using the lowest values of the chosen information criteria. ARCH and GARCH models are intended for the time series' analysis, with the observed instability of the conditional variance. Gold usually has the function of a safe haven, also serving as a warrantor of monetary stability, especially in times of crisis. On the example of 1,151 daily observations on the gold global price and yield rates, the E-GARCH model was applied, the results of which suggest investors to be cautious in their decision-making since the impact of negative shocks (losses) on yield volatility has a strong long-memory effect, making this investments highly risky, especially in bad economic circumstances.
A comparative analysis of tax reliefs for investing in culture in Serbia and Europe
Authors: Marković Sanja , Petrović Jelena , Orlandić Milja
Published: July 2023

This paper analyses the structure of state support for culture through tax relief meant for business entities for their investment in cultural institutions. Tax relief is an incentive from the state which creates a certain behavior among the taxpayers. Therefore, it is a very important segment of the association between economy and culture. Culture is the backbone of the identity of a state, which is an important reason why it should be nurtured and promoted. In this paper, the concept of culture has been narrowed down to include art and cultural institutions of national importance, since they are the most vulnerable virtually the world over, due to the considerable expense required both for the maintenance of the building itself, the funds needed to pay the numerous employees, as well as funding for production itself. In times of crisis, culture is usually the first to be affected by budget cuts. That is why encouragement of direct investments can maintain the level of quality of cultural institutions irrespective of the circumstances.
ICT application and national competitiveness of the Republic of Serbia
Authors: Živković Jelena
Published: July 2023

Information and communication technologies (ICT) are an indispensable part of the modern economic world, and their application can improve the economic development of countries. However, ICT application requires high investment and a highly skilled workforce, which makes it difficult for developing countries to keep up with developed countries. The countries' technological equipment is a crucial factor of national competitiveness, and within the calculation of the Global Competitiveness Index (GCI), particular emphasis is placed on the evaluation of the application of ICT. The paper deals with the Technological Readiness and the ICT adoption analysis of Serbia from 2010 to 2019 and their individual categories. The results showed that Serbia has achieved worse results over the years, being significantly behind the EU in terms of the application of ICT. The worsening results in recent years show that ICT is developing much faster in the world than in Serbia.

The lockdown in Serbia imposed major challenges for parents to take on a 24/7 shift in caretaking, educating, and entertaining their children, while managing to complete the demands of their professional roles and everyday household functioning, along with the constant fear of the virus spreading and potential job loss. This study examines parenting practices (enriching activities, harsh parenting, daily structure, screen time and perception of the increase in screen time) during the COVID-19 lockdown in relation to the perceived parenting stress, parents' socioeconomic status and their working conditions (i.e., without work obligation, working online, working from the workplace). The sample consisted of 1510 mothers of preschool children. Four socioeconomic clusters were identified using the relevant variables (education level, economic status and impact of the pandemic on the financial situation). The results showed that highly educated mothers who worked remotely during the lockdown experienced significantly higher stress of balancing working and parenting than other parents. Mothers who did not work during the pandemic spent more time in enriching activities (p<0.01) and maintained the daily structure better (p<0.01), while mothers who worked remotely perceived a larger effect of the pandemic impact on screen time. The results indicate that, in times of crisis, it is necessary to design the support for the parents of early-aged children corresponding to their specific financial and educational background.

Background/Aim: Erectile dysfunction (ED) drugs are increasingly being used for recreational purposes and improving sexual performance. Oral phosphodiesterase 5 inhibitors are the most popular type of ED drugs among men who have sex with men (MSM). The aim of this study was to assess the prevalence of ED drugs use among MSM in Belgrade and its association with their behaviour and sexually transmitted infections. Methods: A cross-sectional study was conducted at two public health care services in Belgrade and it covered 469 MSM. Data on demographic characteristics, sexual history, sexual behaviour, ED drugs and other recreational drugs use in the previous six months were collected from all participants by the use of a questionnaire. Results: Of all 469 respondents, 16.2% have been using ED drugs. According to the results of multivariate logistic regression analysis, ED drugs users, compared to non-users were older (Odds Ratio - OR=2.60, Confidence interval - 95%CI 2.77-3.84, (p<0,001), had greater number of sexual partners in the last six months (OR= 1.83, 95%CI 1.53-2.18, p<0.001), and more frequently used cannabis (OR=2.55, 95%CI 1.31-4.93, p=0.006) and chemsex in the past six months (OR=3.33, 95%CI 1.69-6.67, p<0.001). Conclusion: ED drugs use among MSM is associated with higher levels of recreational drugs use and high-risk sexual behaviour. Educational messages about the risks and consequences of using ED drugs are needed.

Introduction/Aim: Patients, who stay long in hospitals, nursing homes, and especially in intensive care units, are exposed to the risk of developing chronic wounds. The term "chronic wound" refers to wounds that do not heal despite all treatment measures taken in the period of six to eight weeks. The aim of this retrospective cohort study was to analyze data on chronic pressure ulcers that were collected in intensive care units (ICU) of the Urgent Care Center of the Clinical Center of Serbia during the five-year period, with the aim of determining the factors that influence their occurrence and healing. Methods: The retrospective cohort study was conducted from January 1st, 2018 to April 1st, 2023 at the Urgent Care Center of the University Clinical Center of Serbia in the intensive care units in polytrauma, neurosurgical and surgical patients. The study included 74 patients diagnosed with chronic pressure ulcers. Data for all participants were obtained from medical history and list of discharge. Results: During in-hospital treatment in ICU, pressure ulcers were found in all 74 patients (56.8% of women and 43.2% of men), while combined chronic wounds were found in 57 (77.0%) patients. The largest number of these patients were elderly (70 and older) (31.1%) and with non-traumatic injuries (62%). All patients were tracheotomized with a gastrostomy tube placed. The localization of pressure ulcers was most often in the lumbosacral region (44.6%), followed by the trochanteric region (23.0%). The majority of patients had hypertension (90.5%), diabetes (79.7%) and chronic obstructive pulmonary disease (82.4%), while 28 patients (37.8%) died. 38 patients were underweighted (51.4%), while 11 (14.9%) patients were overweight and obese. Conclusion: Risk factors for the occurrence of pressure ulcers should be evaluated at the moment of the first contact of the doctor with the immobile patient because this is the only prerequisite for timely prevention. Special emphasis should be placed on the elderly, underweight and people with comorbidities.

La obtención de compost a partir de desechos orgánicos resulta una alternativa viable para el medio ambiente, sin embargo son elevados los volúmenes de residuos que se generan sin aprovechar los múltiples beneficios que brinda. El objetivo de esta investigación fue la determinación físico-químico y el contenido de coliformes de un compost obtenido a partir de residuos orgánicos del camal municipal de la ciudad de Riobamba. Se empleó un diseño completamente al azar, con dos tratamientos, T1 que consistió en una mezcla de estiércol seco, contenido ruminal y sangre en la proporción 50:25:25 y adición de caldo bacteriano y T2 con la misma proporción pero sin caldo bacteriano. Se determinó el pH y la temperatura en función del tiempo durante el proceso de digestión aeróbico-bacteriológico. Se obtuvo un compost sólido Bio-sol y se determinaron parámetros físico-químicos y microbiológicos. Los resultados indicaron que ambos tratamientos alcanzaron una temperatura máxima de 70°C. En el tratamiento con bacterias el máximo se alcanzó a los siete días mientras sin bacterias a los 15 días. La sucesión típica de las diferentes fases estuvo mejor definida para el tratamiento sin bacterias. Entre los tratamientos hubo una diferencia de 15 días hasta alcanzar la estabilización de pH. La composición química resultó similar para ambos tratamientos y adecuado para abonos orgánicos.

This paper assesses the risk management practices and organizational performance of public institutions. Specifically, the paper assessed, the types of risks faced by public institutions, the strategies used in managing them and the role of risk management practices in improving organizational performance.  Probability and non-probability sampling techniques were employed to select employees from TANESCO and DUWASA. Both descriptive (multiple responses) and inferential statistics (ordinal regression) were used for data analysis. The findings revealed that public institutions face procurement risks, financial risks, and unethical risks. Risk reduction, risk transfer, and risk acceptance were the preferred strategies to manage risks within organizations. The “Spearman's Rank Correlation” results show that there is a significant and positive correlation between risk treatment (r= 0.735, p= 0.05), risk identification (r=0.528, p=0.01), and organizational performance in TANESCO while there is a significant and positive correlation between risk treatment (r=0.683, p=0.01), risk identification (r=0.461, p=0.05), risk analysis (r=0.450, p= 0.05) and organization performance in DUWASA. Ordinal regression results show that risk management processes (establishing scope, context and criteria = 2.678, risk identification =2.766, and risk treatment= 3.930) were a significant and positive predictor of organizational performance in TANESCO at the one percent level, while risk identification (1.619) and risk treatment (2.158) were significant and positive predictors of organizational performance in DUWASA at the one and five percent levels respectively. Therefore, public institutions should integrate risk management processes with other core functions of the organization if organizational objectives are to be achieved

This study assessed the factors affecting the night market traders’ sales performance. The factors examined were the age, sex, marital status, trade experience, startup capital, number of employees, business type, and years of schooling of a night market trader. The study employed a cross-sectional research design whereby structured and semi-structured interviews were used for data collection. Probability and non-probability sampling techniques were employed to select a sample of 98 night market traders. Data were analysed by using a multiple linear regression model. The findings revealed that traders’ experience, start-up capital, number of employees, business type, years of schooling and sex of a night market trader significantly influenced sales performance. Therefore, entrepreneurial educators should craft strategies and learning environments that validate and stimulate women’s identity in a way that does not compete with the behaviour of the idealised male entrepreneur also government should establish a special campaign to motivate financial institutions to open up a special window for night market traders in accessing loans and accommodate entrepreneurs’ skills in teaching curriculum starting from primary to university education levels
