A iniciação profissional docente e sua relação com a dimensão emocional
Authors: Nogaro Arnaldo , Fussinger Luana , Wisniewski Miriam Salete Wilk
Published: November 2021

A inserção na escola enquanto docente requer, entre tantas coisas, que o professor iniciante relacione os saberes oriundos da formação inicial com as demandas da prática e do contexto escolar. No entanto, a forma como tem ocorrido a inserção não oportuniza esse movimento, fazendo com que os obstáculos e as dificuldades encontradas sejam maiores do que o apoio e amparo que ele encontra. Diante disso, a temática do presente artigo trata do professor iniciante e na relação dos primeiros anos da profissão docente com foco na dimensão emocional para mostrar uma interface que pode ser determinante para que o professor ingresse com segurança, na profissão, tenha confiança e sinta-se motivado a permanecer nela. O caminho metodológico, de caráter qualitativo, contempla a realização de um estudo bibliográfico. Ao propor a discussão sobre a dimensão emocional nos primeiros anos da docência, observou-se, sobretudo, que as emoções, bem como os sentimentos oriundos, constituem a identidade pessoal e profissional do sujeito, a pessoa-professor e suas experiências iniciais. Por isso, acredita-se que o equilíbrio e a maturidade no campo emocional são uma disposição necessária ao professor iniciante, uma vez que com a segurança obtida dessa perspectiva, o mesmo conseguirá lidar com os próprios sentimentos, agir com maior empatia, e por fim, realizar-se no âmbito pessoal e profissional.

The study sought to investigate the epidemiological profile of congenital syphilis in a health region in the State of Ceará, in the period from 2015 to 2019. This is a descriptive epidemiological study, with a quantitative approach, with secondary data collected through the Health System. Information on Notifiable Diseases and Live Birth Information System. There were a total of 248 cases: 65 cases in 2015, 50 in 2016, 45 in 2017, 51 in 2018 and 37 in 2019. The incidence of congenital syphilis was: 8.1 (2015), 6.1 (2016), 5.1 (2017), 5.3 (2018) and 3.9 (2019). In 62.9% of cases from all the years, women were between 20 and 34 years old and in 45.5% of cases they had less than eight years of educational instruction. 57.2% never had a miscarriage, 63.3% had vaginal deliveries and 59.2% had full-term deliveries. Most women received prenatal care (95.9%). In 49.5% of cases, the diagnosis of maternal syphilis occurred during prenatal care. Only 67 (27%) of the pregnant women were treated properly and only 52 (29%) had their partners treated. The study shows a flaw in prenatal care with low effectiveness of the prevention actions, determining factors in the control of congenital syphilis.

Published: November 2021

Basil (Ocimum basilicum L.) is one of the most popular plants cultivated worldwide. It is a good source of natural antioxidants and contains significant amounts of important phytochemicals. Thus, this study aimed to evaluate the macronutrients, minerals, vitamins and bioactive compounds of fresh and dehydrated basil and its hot and cold infusions. The basil presented high moisture (94.12%) and low lipid (0.20%), carbohydrates (5.25%) and dietary fibers (2.33%) content. There was no difference in vitamin C concentrations, total phenolics and antioxidant capacity between fresh and dehydrated basil and between the hot and cold infusions (p > 0.05). Potassium and calcium were the most prevalent minerals in dehydrated basil. The consumption of basil, especially in dehydrated form, can contribute significantly to the daily intake of minerals, vitamins C and E, and infusions are not a relevant choice of consumption to achieve nutritional recommendations.

Authors: Bertan Alessandra Suzin , Silva Séforah Carolina Marques , Cremasco Marco Aurélio
Published: November 2021

Tacrolimus is an immunosuppressant used in the treatment of people who have undergone organ and tissue transplants, as well as in the treatment of dermatoses and eye diseases. Strategies have been carried out to increase the productivity of tacrolimus, since many compounds have in their composition tacrolimus precursors, and bacteria Streptomyces depend on a carbon source for their growth. One strategy is to change the carbon source of the fermentation medium. The present study aims to evaluate the use of coconut oil for the production of tacrolimus via Streptomyces tsukubaensis, as an alternative in the face of glucose, a traditional source of carbon. The batch fermentation process was done in an orbital shaker at 28°C and 130 rpm. Quantification of tacrolimus was performed by High Performance Liquid Chromatography (HPLC). The sugars and proteins, present in the medium, were measured from Somogyi-Nelson and Bradford methods, respectively. According to the results, coconut oil achieved the production of tacrolimus higher than glucose. This is due to the presence of a portion of monounsaturated and polyunsaturated fatty acids that act as precursors to tacrolimus. On the other hand, glucose is a quick carbon source for the bacteria and helps in its growth, but in high amounts it inhibits the production of the drug.

Published: November 2021

Water is an essential natural resource that is being impacted by climate change. Thus, knowledge of future water availability conditions around the globe becomes necessary. Based on that, this study aimed to simulate future climate scenarios and evaluate the impact on water balance in southern Brazil. Daily data of rainfall and air temperature (maximum and minimum) were used. The meteorological data were collected in 28 locations over 30 years (1980-2009). For the data simulation, we used the climate data stochastic generator PGECLIMA_R. It was considered two scenarios of the fifth report of the Intergovernmental Panel on Climate Change (IPCC) and a scenario with the historical data trend. The water balance estimates were performed for the current data and the simulated data, through the methodology of Thornthwaite and Mather (1955). The moisture indexes were spatialized by the kriging method. These indexes were chosen as the parameters to represent the water conditions in different situations. The region assessed presented a high variability in water availability among locations; however, it did not present high water deficiency values, even with climate change. Overall, it was observed a reduction of moisture index in most sites and in all scenarios assessed, especially in the northern region when compared to the other regions. The second scenario of the IPCC (the worst situation) promoting higher reductions and dry conditions for the 2099 year. The impacts of climate change on water availability, identified in this study, can affect the general society, therefore, they must be considered in the planning and management of water resources, especially in the regional context

Authors: Usgodaarachchi L. , Thambiliyagodage C.
Published: November 2021

Graphene oxide (GO) was synthesized using Sri Lankan naturally available graphite and Fe3O4 nanoparticles were successfully incorporated fabricating magnetically separable GO/Fe3O4 nanocomposite. The synthesized nanocomposites were characterized by X-ray diffractometry (XRD), Scanning electron microscopy (SEM), and FT-IR spectroscopy. Crystalline phases of GO and Fe3O4 nanoparticles were identified by XRD patterns, while the presence of functional groups such as –COOH, OH, CH2 was confirmed by FT-IR spectroscopy. SEM images show that Fe3O4 nanoparticles with an average particle size of 107 nm ranging between 56-150 nm are dispersed on GO while restacking and folding of the nanosheets have been observed with incorporation of Fe3O4 nanoparticles. The photocatalytic performance of the photocatalysts was evaluated on photodegradation of methylene blue under visible light irradiation. The GO/Fe3O4 shows better adsorption behavior and excellent photocatalytic activity where it could be successfully used for three cycles without significant activity loss. This is due to the enhanced charge separation resulted due to the presence of GO sheets and better interactions between GO and Fe3O4.

Published: November 2021

Knowledge has become a fundamental asset whose successful application helps organizations to remain competitive while delivering creative products and services. Knowledge intensive firms are organizations that employ highly qualified professionals as the majority and the employees in these organizations are mainly engaged in knowledge intensive activities. IT and Banking industries have been identified as knowledge intensive industries following these conditions and they have been implementing different practices to manage knowledge. However, IT and banking industries are experiencing a high turnover rate. This study aims to identify how the use of knowledge management practices contributes towards employee retention in IT and banking industries. Quantitative approach was used for the research. The sample size was 179, comprising of 97 from IT industry and 82 from banking industry. The data was gathered using a structured questionnaire. There is a strong positive relationship between knowledge management practices and employee satisfaction and employee intention of retention. The study showed that the adoption of knowledge management practices in IT industry is higher than the banking industry. It found that the impact of knowledge management practices on employee retention is slightly higher in IT industry than banking industry. This concludes that, the impact of knowledge management practices on employee retention depends on the industry and retention is high when the adoption of knowledge management practices is high. The results give insights to policy makers and managers of IT and banking industries in developing knowledge management practices.

Determinants of Purchase Intention of Men's Fairness Cream: The Role of Electronic Word of Mouth (e-WoM) Communication in Formation of Product Specific Attitudes of Sri Lankan Millennials
Authors: Samarasinghe G.D. , Jayawardhana W.S.
Published: November 2021

At present male-niche cosmetic market is making radical growth signifying opportunities for all marketers in the industry worldwide. Major cosmetic companies have created dedicated products going beyond “only sanitation”. However, there is a lack of research on this type of product category in a male market, especially in the South-Asian context. Thus, the objective of the present study was to investigate the phenomenon with special emphasis on male Millennials in Sri Lanka as they are very much exposed to and engaged in social media platforms and this significantly influences the formation of their attitudes and perceptions towards products. The key purpose of the study was to explain how purchasing determinants together with electronic Word-of-Mouth (e-WoM) communication affect the male Millennials' attitudes towards the purchase intention of fairness cream. Based on prior literature, a conceptual model was hypothesized. To achieve the objective of the study, data was collected from a sample of 105 males consisting of current users and potential users or non-users of men’s fairness cream. They are executives or above in their professional status aged between 18 to 35. Non-probability convenience sampling methods were adopted in this. The study was quantitative in nature where data collection was carried out based on structured self-administrated questionnaires. The conceptual model and hypotheses were tested using simple Linear Regression models along with descriptive statistics. Findings revealed that both personal factors and product attributes have a significant impact on purchase intention whilst attitude towards consumption of the product category partially mediates the relationship between personal factors and purchase intention. Further, it is found that the presence of e- Word-of-Mouth (e-WoM) communication negatively moderates the relationship between Attitudes towards purchase intention of men’s fairness cream. This study has implications for both theory and practice.

Hypoxia-inducible factor-1α (HIF-1α) is an important regulator of glucose metabolism and inflammatory cytokine production in innate immune responses. Viruses modulate HIF-1α to support viral replication and the survival of infected cells, but it is unclear if this transcription factor also plays an important role in regulating antiviral immune responses. In this study, we found that short and long dsRNA differentially engage TLR3, inducing distinct levels of proinflammatory cytokine production (TNF-α and IL-6) in bone marrow–derived macrophages from C57BL/6 mice. These responses are associated with differential accumulation of HIF-1α, which augments NF-κB activation. Unlike TLR4 responses, increased HIF-1α following TLR3 engagement is not associated with significant alterations in glycolytic activity and was more pronounced in low glucose conditions. We also show that the mechanisms supporting HIF-1α stabilization may differ following stimulation with short versus long dsRNA and that pyruvate kinase M2 and mitochondrial reactive oxygen species play a central role in these processes. Collectively, this work suggests that HIF-1α may fine-tune proinflammatory cytokine production during early antiviral immune responses, particularly when there is limited glucose availability or under other conditions of stress. Our findings also suggest we may be able to regulate the magnitude of proinflammatory cytokine production during antiviral responses by targeting proteins or molecules that contribute to HIF-1α stabilization.

Bacterial infections are a common and deadly threat to vulnerable patients. Alternative strategies to fight infection are needed. β-Glucan, an immunomodulator derived from the fungal cell wall, provokes resistance to infection by inducing trained immunity, a phenomenon that persists for weeks to months. Given the durability of trained immunity, it is unclear which leukocyte populations sustain this effect. Macrophages have a life span that surpasses the duration of trained immunity. Thus, we sought to define the contribution of differentiated macrophages to trained immunity. Our results show that β-glucan protects mice from Pseudomonas aeruginosa infection by augmenting recruitment of innate leukocytes to the site of infection and facilitating local clearance of bacteria, an effect that persists for more than 7 d. Adoptive transfer of macrophages, trained using β-glucan, into naive mice conferred a comparable level of protection. Trained mouse bone marrow–derived macrophages assumed an antimicrobial phenotype characterized by enhanced phagocytosis and reactive oxygen species production in parallel with sustained enhancements in glycolytic and oxidative metabolism, increased mitochondrial mass, and membrane potential. β-Glucan induced broad transcriptomic changes in macrophages consistent with early activation of the inflammatory response, followed by sustained alterations in transcripts associated with metabolism, cellular differentiation, and antimicrobial function. Trained macrophages constitutively secreted CCL chemokines and robustly produced proinflammatory cytokines and chemokines in response to LPS challenge. Induction of the trained phenotype was independent of the classic β-glucan receptors Dectin-1 and TLR-2. These findings provide evidence that β-glucan induces enhanced protection from infection by driving trained immunity in macrophages.
Management of Cough: a practical approach
Authors: Vally M. , Irhuma M. O.E.
Published: November 2021

On a regular day, healthcare providers will be contacted by one or more health seekers presenting with cough as a symptom. Cough has been considered an important physiological reflex that protects the airways from aspiration of foreign materials. Cough is one of the most common symptoms for which people seek medical attention from their healthcare practitioners. The common classifications for cough include acute, subacute and chronic cough. Such classification is time dependant. Acute cough is generally self-limiting, while subacute and chronic coughs have various different causes. There are many different causes of cough, and the common causes of persistent coughs include: upper airway cough syndrome, asthma, gastroesophageal reflux disease (GORD) and even pharmacological therapy. There are other important causes of chronic cough especially in the Southern African region that include: pulmonary tuberculosis (TB), environmental diseases, and others, which will not be covered by this article. Management of subacute and chronic coughs should be individualised according to their cause. Currently, there is no evidence to suggest acute coughs need to be treated. Moreover, there is poor evidence to recommend the use of over the counter (OTC) cough syrups in the management of acute coughs.
The pharmacological management of erectile dysfunction – Update 2016
Authors: Marais André
Published: November 2021

Erectile dysfunction (ED) is a trivial condition with a prevailing incidence worldwide. Phosphodiesterase-5 inhibitors (PDE-5) have revolutionised the treatment of ED and are regarded as one of the most successful drug groups in modern medicine. Generally PDE-5 inhibitors are well tolerated and the incidence of side-effects is low, however a small percentage of individuals experience headache, flushing and abdominal discomfort, resulting in discontinuation of therapy. This has led to the development of second generation PDE-5 inhibitors, displaying more selectivity for the PDE-5 enzyme thereby reducing treatment interruption and improving compliance. Several other treatment modalities, including testosterone replacement therapy and prostaglandin administration are available for resistant or failed first-line treatment. This review provides an update on the current, and future, available drugs used in the management of ED.

Published: November 2021

Background: Emergency contraception (EC) is widely accepted as a safe method of preventing conception following unprotected coitus. Use of EC has been promoted in South Africa, yet uptake among women appears to remain low.Aim: The aim of this study was to access knowledge and use of EC among women presenting for termination of pregnancy at a district hospital in KwaZulu-Natal.Methods: This was a hospital-based cross-sectional study. Data were collected from women attending a termination of pregnancy (ToP) service at a district hospital using a questionnaire and analysed descriptively.Results: A total of 218 women participated, of whom 25% were under 20 years of age and 87% were single. Reported knowledge of EC was good with 70% of participants indicating that they knew about EC. However, knowledge around EC was not complete, with less than 50% knowing the time interval between intercourse and EC action and some believing that EC acted by inducing an abortion. Reported usage of EC was only 40%.Conclusion: This study revealed that there is much more to be done to enhance knowledge and use of EC in this context. Reasons for the discrepancy between knowledge and usage need further exploration.
A free boundary problem for binary fluids
Authors: Benzi Roberto , Bertsch Michiel , Deangelis Francesco
Published: November 2021

A free boundary problem for the dynamics of a glasslike binary fluid naturally leads to a singular perturbation problem for a strongly degenerate parabolic partial differential equation in 1D. We present a conjecture for an asymptotic formula for the velocity of the free boundary and prove a weak version of the conjecture. The results are based on the analysis of a family of local travelling wave solutions.

from the source-to-solution map of the cubic wave equation

\Box_{A}\phi+\kappa |\phi|^{2}\phi=f

, where

\kappa\neq 0

and

\Box_{A}

is the connection wave operator in the Minkowski space

\mathbb{R}^{1+3}

. The equation arises naturally when considering the Yang–Mills–Higgs equations with Mexican hat type potentials. Our proof exploits the microlocal analysis of non-linear wave interactions, but instead of employing information contained in the geometry of the wave front sets as in previous literature, we study the principal symbols of waves generated by suitable interactions. Moreover, our approach relies on inversion of a novel non-abelian broken light ray transform, a result interesting in its own right.

An ecological study of algae at River Ginzo in Katsina town was carried out for six weeks at three different sites. In this study, various strains of native microalgae were identified and isolated. The water's physicochemical properties were analyzed at Kofar Marusa, Kofar Sauri, and Kofar Durbi of River Ginzo in Katsina State. The physicochemical parameters studied showed temperature and pH range of 28oC to 31oC and 6.42 to 7.36. A total of eighteen (18) algal species were identified, out of which Ten (10) species belong to the Class Chlorophyceae with Spirogyra species having the highest cell counts, five (5) species belong to the Class Cyanophyceae with Oscillatoria species having the highest cell count and three (3) species belong to the Class Bacillariophyceae with Nitzchia spp having the highest cell counts. Among the isolates, Chlorella species showed an increased growth rate with higher biomass productivity of (88.67±2.57) X 104 (cell/ml) after six days of incubation. The results showed that Chlorella, Spirogyra, and Oocystis species could be a possible candidate species for producing oils for sustainable biodiesel production, based on their high growth rate and presence in all the locations.

Published: November 2021

Albizia zygia produces valuable timber which has received some level of prominence in the international market. However, the seeds are dormant, and the tree species remain undomesticated. This study was conducted to evaluate the effect of seed size and presowing on the germination of Albizia zygia in a nursery. Seeds were grouped into four categories in regard to their length, small (≤0.5 cm), medium (> 0.5 < 0.8 cm), large (≥0.8 cm), and mixture of small, medium, and large seeds. The seeds were subjected to five main seed pretreatment methods, namely, soaking in sulphuric acid (H2SO4) for 2 minutes, mechanical scarification, soaking in hot water for 5 minutes, soaking in cold water for 24 hours, and control where seeds were sown without any treatment. The results indicate that combination of mechanical scarification and large seeds produced the highest (100%) germination. Hot water treatment was effective in large seeds producing 69.0% germination. The increased germination for mechanically scarified seeds suggests that seed dormancy in Albizia zygia is mainly due to its hard seed coat. Therefore, it is recommended to farmers to adopt use of mechanical scarification and large seeds, since it is safe and effective.

Published: November 2021

Electrical Resistivity Imaging (ERI) is a useful near-surface imaging technique, which mainly include data acquisition, numerical modelling and tomographic inversion. Within the study area, only one – dimensional (1-D) Electrical Resistivity survey has been carried out for Geophysical investigations. Therefore, 2-D ERI survey was carried out at the Igwete Primary School, Amai to provide electrical picture of the subsurface from which discrete bodies and lithology are better revealed vertically and in lateral extent. The 2-D ERT survey data were acquired using the Petrozenith Earth Resistivity meter while employing the Wenner electrode array. The 2-D apparent resistivity data were inverted to obtain true resistivities of the subsurface using res2dinv software running on personal computer. The subsurface resistivity models were displayed as pseudo sections and inverted resistivity section in the form of colour shaded contour maps. The inverse resistivity model images indicate that at a lateral extent in the range (15.00-21.00) m and (33.00-39.00) m, anomalies suspected to be gravel mixed with sand is in place with resistivities of about (254.00-948.00) Ωm. From the geologic section we can infer that a geological formation is observed at a lateral position of (27.00-32.00) m of resistivity in the range (90.00-93.00) Ωm. This structure is inferred to be a clay pocket. The sandy nature of the formation requires that underground water development be sought for at (9.00-15.00) m over a depth (2.30-8.00) m in the sandy environment. Results of 2D resistivity imaging has helped to delineate the lithology which comprise mainly of; sand, sandy clay, clayey sand depositional environment. The resistivity of these lithology falls in the range (90.00-93.00) Ωm with depth to formation of about (2.30-6.00) m.

The ratios of unripe plantain into African yam bean are 100:0, 90:10, 80:20, 70:30, 60:40 and 50:50. Chemical and functional properties of composite flour as well as overall acceptability of the product were evaluated. The result of moisture content is within safe limit to ensure shelf stability. Crude protein (6.87-12.98) and ash (2.43-6.57%) increases with increasing proportion of African yam bean into unripe plantain flours, while carbohydrate (66.27-56.77) and crude fibre (1.46-1.11%) decreases. The bulk density ranged from (0.92-3.34 g/ mL), water absorption capacity (1.07-1.60%), least gelation capacity (4.10-14.23%), and swelling power 1.49-1.77 g/g at 50 oC, 1.54-1.88 at 60 oC, 2.63-2.89 at 70 oC and 4.42-6.60 g/g at 80 oC, respectively. The solubility index ranged from 1.49-1.77 at 50 oC, 1.54-1.88 at 60 oC, 2.63-2.89 at 70oC and 4.42-6.60 g/g at 80 oC. The sensory evaluation showed no significant difference in taste, colour, texture/mouth feel and aroma while sample with 30% African yam bean flour has the highest value in overall acceptability. Enrichment of unripe plantain with African yam bean flours significantly increases its nutritional value which has the potential to combat protein-energy malnutrition and micronutrient deficiencies in Nigeria and Africa as a whole.

Effects of acute and sub-lethal concentration of Datura stramonium on growth and some haematological indices on fingerlings of Clarias gariepinus were investigated. Acute lethal toxicity (LC50) of D. stramonium leaves extracts for 48 hours exposures of C. gariepinus were determined at 0.2 ml/L. Clarias gariepinus fingerlings (4.22±0.01g) were exposed to D. stramonium at 0.00, 0.002, 0.02 and 0.2 ml/L for 28 daysand 10 days withdrawal. Each treatment was stocked 20 fish per replicate and replicated twice. Growth indices, haematological parameters, and histology were determined. The result shows a general increase within the weightgain among the treatments but the value decreases as the concentration of D. stramonium increases. The haematological response to D. stramonium exposures was very variable relative to the exposed concentration. Theresult obtained after 10 days withdrawal of haematology was relatively almost like the values obtained within the control and before the experiment. Histology revealed the gills, liver and intestines of C. gariepinus for the control shows no lesions, while the exposed groups recorded like moderate lamellar atrophy, and moderate diffuse hepatocellular degeneration. The results indicate that the exposure to sub-lethal levels of D. stramonium impacted on the growth, blood profiles, and histology of the exposed fish.
Localisation of SDGs in Higher Education: Unisa’s whole institution, all goals and entire sector approach
Authors: Nhamo Godwell
Published: November 2021

This paper documents the processes leading to the hosting of the University of South Africa (Unisa) Sustainable Development Goals (SDGs) Localisation Indaba1 in November 2019. Of interest is how the programming, which started as a purely inreach community engagement project, ultimately embraced the whole institution, all SDGs and the South African higher education sector. Data was generated via two platforms, namely participatory action research and a survey evaluating the Indaba. The following cycles emerged: the development of a Unisa Management Policy Brief calling for the SDGs Localisation Indaba in 2017 (Cycle 1); the development of an SDGs for Society Research Stream as part of the Unisa Annual Interdisciplinary Academy and Summer School in 2018 (Cycle 2); and the SDGs Localisation Indaba in 2019 (Cycle 3). The Indaba led to the SDGs Localisation Declaration which resulted in the formation of the SDGs Liaison Committee. Several agreements were made to expand SDGs localisation at Unisa. Finally, the Indaba attracted many participants from outside Unisa, especially from other institutions of higher education. However, it took almost three years to realise the SDGs localisation dream at Unisa. The key recommendation is thus that those championing SDGs localisation should be prepared to continue moving forward despite delays due to management changes and processes.Keywords: Higher education, sustainable development goals, domestication, localisation of the SDGs Introduction
Internal Parametricity for Cubical Type Theory
Authors: Cavallo Evan , Harper Robert
Published: November 2021

We define a computational type theory combining the contentful equality
structure of cartesian cubical type theory with internal parametricity
primitives. The combined theory supports both univalence and its relational
equivalent, which we call relativity. We demonstrate the use of the theory by
analyzing polymorphic functions between higher inductive types, observe how
cubical equality regularizes parametric type theory, and examine the
similarities and discrepancies between cubical and parametric type theory,
which are closely related. We also abstract a formal interface to the
computational interpretation and show that this also has a presheaf model.

Somatizar el castigo: un análisis de las experiencias de enfermedad y encierro penal de una mujer afroecuatoriana
Authors: Beltrán Vanessa
Published: November 2021

Este artículo indaga en las experiencias de enfermedad e internamiento penal de Analía Silva, una mujer afroecuatoriana y cofundadora de la organización Mujeres de Frente (MDF), quien fue condenada en múltiples ocasiones por el microtráfico de drogas y diagnosticada en el 2017, con una insuficiencia renal crónica. A través de la reconstrucción etnográfica del proceso de deterioro de su salud (2017-2020), se propone un análisis en torno a la pregunta; ¿Cómo se encarnan los procesos de desposesión y encierro penitenciario en la experiencia de enfermedad de una mujer empobrecida y racializada por el estado penal ecuatoriano? Se propone el argumento de que, en la intersección de sus experiencias de enfermedad y castigo penal, se encarnan los vínculos que unen la cárcel, la clínica y la calle como contextos expresivos del régimen securitario que ha guiado la gestión pública de la salud y el castigo penal en Ecuador, en las últimas décadas. El ingreso metodológico por la noción de cuerpo-territorio permitió develar la experiencia de padecimiento y encierro como síntomas de un sistema de organización social regido por la exclusión y el abandono selectivo del estado, que en los procesos de tratamiento de enfermedades como la insuficiencia renal crónica, se reproducen violencias normalizadas bajo la jerarquización del conocimiento y la instauración de ordenamiento moral castiga como indisciplina, la denuncia y la contestación y que en medio de contextos de sujeción, también es posible encontrar tejidos de politización con potencial transformador.
Assessment of Groundwater Recharge Potential Depending on Morphologic Analysis in East of Wasit, Southeastern Iraq
Authors: Shamkhi Mohammed S.
Published: November 2021

Modern technologies are used for watershed management to cope with drought risks in arid and semi-arid regions. The study aimed to conduct a morphometric analysis and know potential groundwater recharge areas in the eastern region of Wasit Province. Remote sensing and GIS data were used for morphometric analysis. The morphometric analysis results adopted the Digital Elevation Model. The results of the analysis were verified by matching the results with what exists in reality. The area of the first basin was 1482.017, as it is the largest basin from the area, with a percent of 51.228% of the total area of all basins. The percentage of first-degree flows reached 83.37% in the first basin, 74.14% percent in the second basin, 75.51% in the third basin, and 75.75% in the fourth basin from all streams in each basin. The bifurcation rate (3.135-4.233), Stream frequency range values (0.543-0.332), drainage texture coarse, low drainage density that ranged between 0.986-1.14 km/km2 elongation ratio ranging from 0.348-0.624 form factor (0.095-0.316). The basins' circularity (0.105-0.238) relief value (951-112) m infiltration number value (0.369-0.535). All basins have a longitudinal shape and lead to the formation of floods and rapid currents, which exposes the region to rapid seasonal floods and the creation of flash floods that cause soil erosion and analyses the drainage intensity results. It was low, and this is an indication that the ground has high permeability. The flow frequency results indicate that the area is semi-arid and exposed to small amounts of rain and coarse drainage texture by comparing the result parameters from morphometric analysis results for each basin. The potential recharge areas of groundwater in the study area can be known, n as the analysis results showed that recharge potential occurs in all basins. The highest groundwater recharge is possible in the third basin and the lowest in the first basin. Morphometric analysis was performed by ARC-GIS(Arc-map10.4).
Informal operators in waste management in Accra, Ghana: From neglect to recognition?
Authors: Boampong Owusu , O. Britwum Akua , D. Akorsu Angela
Published: November 2021

Informal waste collectors play an essentialrole in urban solid waste management; however,in many developing countries, they are neglectedin the waste management policy framework. Thispaper explored the policy regime of informal waste operators in waste management in Accra, Ghana.Drawing on qualitative data from in-depth interviews and focus group discussions with informal waste collectors, private waste companies and officials of Accra Metropolitan Assembly, the paper shows that formal waste contractors with concession rights underserve low-class areas due to operational difficulties. The informal waste collectors fill this gap by providing services to these underserved communities though they have no legal entitlement to the concessions. The formal waste contractors and the municipal authorities recognize this gap filling role of informal waste collectors in waste management in Accra yet fail to provide the official recognition to legitimise their participation in solid waste management. The lack of official recognition, even in formal policy documents, undermines the development of informal waste management services as a viable employment option. It also denies a substantial section of the residents in poorer neighbourhoods in the national capital access to affordable and efficient waste management services.
Gradation of stakeholder participation in water resources management in the Densu Basin in Ghana
Authors: Anokye Nana Amma
Published: November 2021

The literature shows that degrading water resources is partly due to the lack of stakeholder participation in its management. It also underscores that intensive stakeholder participation is vital for democracy, good governance, and sustainable development in water resources management. However, the gradation of stakeholder participation in water resources management has not been widely studied. I applied the extended ladder of participation in water resource management in the Densu Basin in Ghana. I collected data through 123 interviews and 26 focus group discussions in addition to an examination of policy and legal documents on water resource management. My findings show that the activities that affect the lives of the communities influence the intensity of their participation in the Densu Basin. I therefore recommend that for local people to manage their water resources sustainably and intensively, government and non-governmental agencies must link management activities with local livelihoods and create awareness of the importance of the ecosystem to community sustenance. My findings again show that inducing communities through economic incentives is only appropriate for short term water resource management needs as such incentives cannot be sustained. However, an approach that stimulates communities to participate through their own initiatives after being helped to identify their needs is likely to lead to intensive and sustainable participation in water resource management.
