Published: December 2022

The objective was to identify yeast NG17, a newly isolated oleaginous yeast obtained from soil in Thailand and to characterize its oil yield and composition in sugarcane leaves hydrolysate (SLH), a sustainable resource. Biochemical and phylogenetic approaches were used to characterize yeast NG17, and its lipid content was determined by gas chromatography. Yeast NG17 was placed in the genus Candida, but not identified to species. It had an oil content of 27.9% (w/w, dry weight) with a major fatty acid composition of oleic (57.6%) and palmitic (25.4%) acids when grown in a high carbon/nitrogen (C/N) ratio medium for 6 d. The oil yield of Candida sp. NG17 was 2.3 g/L when grown in SLH, which contained 18.7 and 19.1 g/L glucose and xylose, respectively, without any supplementation. Meanwhile, the oleic and palmitic acid composition of the oil was reduced to 48.5% and 22.1%, respectively. The oil yield obtained in SLH was higher than that in the detoxified SLH (2.1 g/L). Increasing the SLH pH to 6.5 resulted in an increased oil yield to 5.07 g/L. Supplementation of SLH (pH 6.5) with 0.1% (w/v) KH2PO4 further increased the oil yield of Candida sp. NG17 to 6.67 g/L. Overall, Candida sp. NG17 is a good source of oil for renewable oleochemicals and biodiesel production.

Authors: Wang Yuan , She Shuai , Zhou Nan , Zhang Junguo , Yan Hao , Li Wenbin
Published: December 2022

A new method for wood identification using terahertz (THz) time-domain spectroscopy (TDS) is presented. THz-TDS technology is an emerging method of spectral analysis method that shows great advantages in wood non-destructive testing. Wood is opaque in the optical and near infrared spectrum, and relatively transparent in the THz band. In this experiment, four wood species (Pinus densiflora, Pinus sylvestris, Pseudotsuga menziesii, and Cunninghamia lanceolata) were selected as samples. Optical parameters such as absorption coefficient and refractive index of the measured samples can be extracted from THz time-domain spectra. Principal component analysis was introduced to reduce the dimensionality of the THz spectral data of the wood. The principal component score matrix of the wood was obtained and used as a characteristic matrix. A wood classification model was established using a support vector machine. The experimental results showed that THz-TDS had excellent performance in wood recognition. This research lays a theoretical and application foundation for the application of THz technology in the field of wood detection and recognition. It also provides a new direction and technical scheme in the wood identification field.

Published: December 2022

The effect of ethylenediamine (EDA) treatment on cellulose nanofibers (CNFs) remains unclear. To study the effect of EDA treatment on the gelation of the fibrillated CNFs, hydrogels that received 1, 2, and 3 EDA-treatment/washing cycles were prepared and analyzed. Different concentrations of the EDA treatment were also used to prepare hydrogels. Both X-ray diffraction and Fourier transform infrared studies showed that cellulose I/II hybrid hydrogels were fabricated from CNFs via 2 or 3 cycles of 99 wt% EDA treatment and then were washed with water. Field emission scanning electron microscopy observations indicated that the obtained CNF-based hydrogels presented some aggregations via the coalescence of adjacent individual CNFs. Moreover, the hydrogel film with a cellulose I/II crystal structure showed a higher tensile strength of 2.4 MPa and a fracture strain of 23.5%. This was because it had an entangled continuous nanonetwork structure formed after repeated EDA treatment. The authors hope that this work can further stimulate interest in the development of CNF-based hydrogels with multiple structures, properties, and functions for a variety of applications.

Published: December 2022

The presence of lignin sheaths and the crystalline structure of cellulose are two key barriers in the development of corn stover (CS). To remove these two barriers and improve the digestibility of carbohydrates in CS, CS (pretreated by H2O2, H2SO4, NaOH, an enzyme, steam explosion [SE], and SE combined with NaOH [SE-NaOH]) was hydrolyzed. The total reducing sugar yield (Ytrs), accessibility of the enzyme to the substrate (Kobs,0), and gradual loss of the enzyme activity (Ki) were compared by regression analysis of the kinetic model, scanning electron microscopy, Fourier transform infrared spectroscopy, and X-ray diffraction analysis. The pretreatment dramatically increased the Ytrs and Kobs,0, and remarkably decreased the Ki. The maximum increase in the Ytrs (106.57%) was obtained after the saccharification reaction of the CS pretreated by SE-NaOH. Physicochemical characterizations of the CS pretreated by SE-NaOH showed that the SE-NaOH pretreatment effectively reduced the lignin sheath, decreased cellulose crystallization, and created favorable conditions for enzymatic diffusion and penetration.
Determination of alkali and sulfite ratios in paper pulp produced from sorghum stalks via the kraft method
Authors: Gençer Ayhan , Hatıl Ceyda
Published: December 2022

Paper pulp was produced by the kraft method using sorghum (Sorghum bicolor × S. bicolor sudanense) as the fibrous raw material. Two groups were cooked using active alkali at 10% and 14%. For each group, five sulfite ratios (0, 4, 8, 12, and 16%) were used, making a total of 10 different groups that were cooked. A literature study was conducted to determine the cooking temperature, the time needed to reach the maximum temperature, and the duration of cooking time at the maximum temperature. A total of 30 batches of paper were obtained from pulps without beating and from pulps beaten at values of 35 ± 2 °SR and 50 ± 2 °SR (Schopper Riegler) freeness. The aim was to determine the most suitable alkali and sulfite ratios by conducting standard tests for the yield, kappa number, and viscosity of the screened pulps and for the papers obtained from these pulps. The highest screened yield of cooked pulp was obtained under conditions of 14% active alkali and 12% sulfite. Since the mechanical properties of the paper obtained from this pulp were satisfactory when compared with those in the literature, it was concluded that these ratios could be recommended as a condition for cooking.

Authors: Kaçamer Serdar , Budakçı Mehmet
Published: December 2022

Optimum application values of the Water Transfer Printing (WTP) technique were determined on various wood-based panel surfaces. For this purpose, 8-mm-thick, glossy white, acrylic-coated medium-density fiberboard (MDF) panels (high gloss panels), polyvinyl chloride (PVC)-coated MDF panels, MDF Lam ready-to-use panels, and cellulosic, polyurethane, acrylic, and water-based paint applied MDF panels were used. An automatic immersion system with pool was designed and produced. A 30-μm-thick carbon patterned WTP film was applied on sample panel surfaces prepared with the help of this device at four immersion angles (0º, 15º, 30º, and 45º), four immersion speeds (50 cm/min, 100 cm/min, 150 cm/min, and 200 cm/min), and four immersion times (5 to 10 s, 20 to 30 s, 50 to 60 s, and 80 to 90 s). The optimum parameters of the WTP technique regarding the temperature and relative humidity of the application environment, water temperature, laying method, dissolution time, amount of activator, spray gun angle and tip clearance, air pressure, as well as immersion angle, speed, and time were determined using the measurement and observation method. According to the optimum parameters obtained in the study, the WTP technique was successfully applied to all wood-based panel surfaces.

Visualization of a streak line pattern in a mixing vessel is quite useful for understanding the mixing mechanism and designing an optimal mixing vessel. However, conventional experimental methods for visualizing streak lines require a lot of time to construct impellers and prepare solutions. Although various commercial fluid analysis software has been developed, there are still no examples of its use for calculating streak lines in mixing vessels. A simulation method was developed to quickly evaluate the streak line pattern in a laminar mixing vessel by numerical analysis with commercial code. A commercial CFD code can calculate streak line patterns in a laminar mixing vessel. It was found that a lattice method was more suitable than a particle method for the simulation of the streak line.

The space propulsion systems ensure se veral start-ups and shutdowns of main liquid-propellant rocket engines under microgravity conditions for the spacecraft program movements and reorientation control. During the passive flight of the space stage (after its main engine shutdown), the liquid propellant in the tanks continues to move by inertia in microgravity away from the propellant management device as much as possible. In this case, the pressurization gas is displaced to the propellant management device, which creates the potential danger of gas entering the engine inlet in quantities unacceptable for the reliable engine restart. In this regard, determining the parameters of fluid movement in propellant tanks in microgravity conditions is an urgent problem that needs to be solved in the design period of liquid propulsion systems. We have developed an approach to the theoretical computation of the parameters of the motion of the ‘gas — fluid’ system in the propellant tanks of modern space stages in microgravity conditions. The approach is based on the use of the finite element method, the Volume of Fluid method and modern computer tools for finite-element analysis (Computer Aided Engineering — CAE systems). For the passive leg of the launch vehicle space flight, we performed mathematical modeling of the spatial movement of liquid propellant and forming free gas inclusions and determined the parameters of movement and shape of the free surface of the liquid in the tank as well as the location of gas inclusions. The numerical simulation of the fluid movement in an experimental sample of a spherical shape tank was performed with regard to the movement conditions in the SE Yuzhnoye Design Bureau ‘Drop tower’ for studying space object s in microgravity. The motion parameters of the ‘gas — fluid’ interface obtained as a result of mathematical modeling are in satisfactory agreement with the experimental data obtained. The use of the developed approach will significantly reduce the amount of experimental testing of the designed space stages.

Tratamiento informativo del síndrome de la resignación. Un discurso sobre las familias refugiadas
Authors: Mhanna-Mhanna Eman
Published: December 2022

Este trabajo forma parte del proyecto DIPURE, en el que investigadores de las universidades de Almería, Murcia y Cardenal Herrera de Valencia han examinado desde distintas perspectivas el discurso público sobre los refugiados en España. En esta ocasión, nuestro objeto de estudio conjuga lo migratorio con lo sanitario, pues nos hemos ocupado del discurso periodístico sobre el síndrome de la resignación, que, según la escasa investigación que se ha realizado sobre él, afecta únicamente a niños que solicitaron asilo en Suecia. Para examinar el tratamiento del síndrome de la resignación en los medios españoles, hemos observado una muestra de la prensa escrita publicada desde 2015, año en el que empezó a aumentar de forma considerable el número de personas refugiadas en el mundo, hasta junio de 2021. El estudio se enmarca en el hipergénero conocido como debate social y los principales resultados del estudio están estructurados en tres dimensiones: la primera afecta al espacio y al tiempo; la segunda, a los actores y la tercera, a las valoraciones y argumentaciones.
Voz y discurso en salud mental: esquemas diagnósticos en conflicto en un análisis de caso
Authors: Bonnin Juan-Eduardo
Published: December 2022

En este trabajo presentamos un caso de error de diagnóstico en salud mental que, iniciado en la entrevista de admisión, se prolongó durante un año de tratamiento. Para interpretar las causas de dicho error, y basados en un proceso colaborativo con el equipo de salud mental, utilizamos dos categorías teóricas: “discurso” (entendido como el conjunto de regularidades semióticas y semánticas que se corresponden con un campo social, como en “discurso médico”, etc.) y “voz” (entendida como el producto singular de la articulación entre múltiples discursos a lo largo de la trayectoria biográfica de una persona). Metodológicamente, empleamos las herramientas descriptivas del análisis de la conversación en un corpus heterogéneo que atraviesa las diferentes etapas del diagnóstico y el tratamiento. El análisis muestra el efecto del discurso psicoanalítico, que selecciona algunos aspectos de la voz de la paciente ignorando otros, arribando a un diagnóstico de trastorno de conversión (“histeria”) e impidiendo otro, de afasia progresiva. En el final, se discute el potencial de los estudios de la interacción para el proceso diagnóstico y algunas implicancias del caso para el campo del análisis del discurso.
Narrativas del dolor: técnicas conversacionales y recursos de mitigación e intensificación
Authors: Ciapuscio Guiomar-Elena
Published: December 2022

El artículo se enmarca en estudios precedentes sobre narraciones orales, específicamente, en enfoques que conciben las actividades conversacionales como un proceso de (co)construcción de los interlocutores (Gülich/Schöndienst/Surmann; Gülich 2007). Me propongo profundizar en el conocimiento las formas de reconstrucción narrativa que se emplean para relatar crisis cardíacas, y en los procedimientos de formulación para representarlas (Gülich/Kotschi; Brünner/Gülich; Ciapuscio 2003). Por otra parte, estudio los recursos lingüísticos para verbalizar la intensidad –mitigación o intensificación– del dolor y de los síntomas asociados (Mihatsch/ Albelda; Albelda/Mihatsch). El análisis ejemplar está basado en un corpus de seis entrevistas de ingreso entre cardiólogos y pacientes, que tuvieron lugar en un hospital público del Gran Buenos Aires.

En este trabajo presentamos los resultados de la documentación, mediante prospección arqueológica super_cial intensiva, de una posible choza ganadera localizada en la Dehesa de Villargordo (Villafranca de los Barros, Badajoz). Este hábitat debió depender del cercano asentamiento de Villargordo que, situado en un cerro al otro lado del arroyo de Bonhabal y junto a la Vía de la Plata, estaría controlando y explotando a nivel pecuario esta zona de dehesa entre el Alto Imperio Romano y la Alta Edad Media. Gracias a los datos recabados se ha podido efectuar un análisis espacial de densidad de núcleo para concretar la localización de la choza dentro del espacio de la extinta dehesa, permitiendo además este análisis valorar la tasa de desplazamiento lateral de materiales arqueológicos derivada de la acción del arado agrícola, así como discriminar los artefactos por grupos funcionales y por cronología. Todo ello, junto al estudio de los materiales diagnósticos y a una aproximación histórica a las transformaciones del paisaje, nos ha ayudado a interpretar el sitio documentado a nivel cronológico, funcional y económico.

Published: December 2022

Introduction and aim. The aim of this study was to examine the usability of blood urea nitrogen to serum albumin ratio (BAR) as a prognostic predictor of in-hospital mortality in patients with gastrointestinal (GI) bleeding. Material and methods. The electronic medical records of the patients who applied to the emergency department due to upper GI bleeding during the study period were reviewed. The receiver operating characteristic (ROC) curve and the area under the curve (AUC) were used to evaluate each discriminant cut-off value to estimate mortality. Results. The study included 225 patients. The median (IQR) age of the patients was 75.0 (68.0–84.0) and 94 (41.8%) were female. AUC was determined as 0.784±0.055 (95% CI, 0.677–0.892) for BAR (p<0.001) in terms of in-hospital mortality. The cut-off value of BAR for this outcome was calculated as 16.26. In this cut-off value, sensitivity was 71.43%, specificity 82.84%, positive predictive value (PPV) 30.00% and negative predictive value (NPV) 96.57%. Conclusion. BAR is a useful tool that can be used to predict the in-hospital mortality of patients with GI bleeding. Patients with GI bleeding with a BAR above 16.26 will require more aggressive and timely intervention.
Mātauranga Māori, inquiry and creative music-making in the primary music classroom: A Pākehā teacher’s journey
Authors: Dunn Sarah , Locke Milly
Published: December 2022

This article draws on a master’s study into programme decisions and processes of a Pākehā primary music teacher who sought to include mātauranga Māori (Māori knowledge), tikanga Māori (Māori practices) and te ao Māori (a Māori way of seeing the world) in their teaching practice. The study investigated how children are enabled to experience mātauranga Māori within an inquiry approach to teaching and learning, through engagement with taonga pūoro (singing treasures) and the whakataukī (proverb) of the whakapapa (genealogy) of Māori music as stimuli for creative music-making. Drawing on action research and self-study, I conducted an intervention of eight music lessons with 28 children from Years 3 and 4. Findings emerged from an analysis of student questionnaires, my teacher journal, student reflections, and scores and audio recordings of students’ creative music-making.In this article I focus specifically on two aspects of my findings:1. The way that the teacher-as-learner position within inquiry pedagogy complements the ethos of ako (reciprocal learning), and the way a holistic, integrated learning approach is supported by the centrality of interconnection within te ao Māori.2. The process by which a teacher might use the whakapapa of Māori music as a conceptual framework for inspiring a sound palette of the natural world in children and for scaffolding creative music-making.As a teacher I found that I could establish whanaungatanga (a family-like connection) in the primary music classroom through a relational pedagogy and valuing the children’s individuality through collaborative processes. This small study reinforced my belief that teachers need to take responsibility for their bicultural practices in the classroom, that a complementary ethos of inquiry and Māori approaches to teaching and learning can be fostered, that inquiry pedagogy can be effective in music education, and that practical approaches for experiencing Māori knowledge, inspired by Māori music, can flourish in the primary music classroom.
Developing mathematics-enhanced chemistry research lessons through productive lesson study: Insights from in-service teachers
Authors: Samaniego Katherine Kate B. , Espinosa Allen A.
Published: December 2022

This study explores the perceptions of five in-service chemistry and mathematics teachers in using productive lesson study as a framework for teaching and learning. Introductory professional development workshops on horizontal articulation, productive pedagogy and lesson study were given to teachers at the onset of the project. Teachers were then tasked to produce two research lessons for grade 10 chemistry using the productive lesson study framework. We utilised inductive thematic analysis to identify the themes underpinning the perceptions of the teachers. Findings show that the teachers improved and deepened their knowledge by learning from each other’s perspectives. They had also adopted effective strategies for teaching by reflecting on their students’ learning, which helped them address the challenges of integrating and relating different topics into one. Furthermore, they became more aware of their students’ prior knowledge which enabled them to address misconceptions. Thus, learning was reinforced, broadened and extended. Participating in the study made a transformative intervention in the teachers as they became more focused on the enhancement of their professional practice as teachers.
International Higher Education as Foreign Policy: Comparing the Strategies of the EU, China, and Russia Towards Central Asia

Published: December 2022

The article sheds light on the nexus between higher education and foreign policy. International higher education has become an increasingly prominent element of some states’ policies towards other countries as a flank to traditional foreign policy. It has occurred in Central Asia, where the European Union, China and Russia are all supporting teaching, research and capacity-building activities in the tertiary sectors of Kazakhstan, Uzbekistan and Kyrgyzstan. Although they employ similar tools and instruments, the assumptions and visions underpinning their respective strategies diverge. Russia’s strategy is shaped by historically informed identity factors and the impulse to entrench predominance in the post-Soviet space, whilst China uses its support for higher education as a soft infrastructure for its Belt and Road Initiative (BRI). Meanwhile, the EU has integrated higher education into its strategy for the region, which aims at drawing Central Asia closer to its orbit through democratisation and the rule of law.
Engagement of the Judiciary in the Political Activity of the Ruling Camp. A Case Study of the Venezuelan Supreme Tribunal of Justice
Authors:   Wojskowa Akademia Techniczna (Poland), Kowalski Wawrzyniec
Published: December 2022

This article aims to define the role played by the Supreme Tribunal of Justice in the political system of contemporary Venezuela and determine the extent of the executive branch’s influence on the judiciary. The research problem formulated by the author concerns the determination of the fundamental importance of the Tribunal in keeping the Chavistas in power. The paper compares the substantive legal competencies of the Supreme Tribunal of Justice with the political realities of recent years and shows why the Tribunal’s activities undertaken in recent years have raised so much controversy. It has been pointed out that the Chavistas’ control of the Supreme Tribunal of Justice is a significant factor enabling the supporters of Nicolas Maduro to exercise both judicial and extrajudicial control over the institutions of the judiciary and to influence the legislature, vide the deprivation of legislative powers already accomplished.

The difference in the methodology of conducting military operations by Russian and Ukrainian troops during the war ongoing since February 2022 is striking. It does not result only from the adopted convention of conducting these activities but is conditioned on a much deeper mental level resulting from cultural conditions. They determine the perception and understanding of the phenomenon of war. In other words, the operational and tactical methodology can be adapted to changing realities, provided that the essence of such a change is understood in terms of achieving the assumed military and non-military goals. Furthermore, these goals could be achieved by conducting military operations according to a completely different methodology, probably with much greater effectiveness. Why, in such a perspective, did the Russian side choose such a barbaric way of conducting war, characterising the methodology of military actions of the past decades or even centuries? This paper aims to answer the research question: What premises condition the Russian methodology of military action in the Russian-Ukrainian war of 2022? Empirical methods were employed to obtain an answer to this question.

In modern turbulent conditions, the ecosystem approach, the study of anthropo-ecosystems (industrial, innovative, entrepreneurial), is of particular relevance. This is a new concept designed to explain the contradictory nature of interorganizational and interpersonal interactions. The purpose of the study is to develop an analytical model of the company's ecosystem and assess the ecosystems of a number of large industrial enterprises of the Russian Federation in order to identify common characteristics and differences in ecosystems responsible for sustainable regional and interregional development. When the goal was achieved, conceptual, theoretical, methodological and practical tasks were solved. The set of the applied methods included content analysis, comparative analysis, modeling and systematization. The research procedure consists in considering the ecosystem from an institutional position as a new form of coordination of economic relations between stakeholders and the core of the ecosystem based on the principle of unity of the internal and external environment (the principle of seamlessness). The hypothesis is being tested that enterprise ecosystems can be compared with each other regardless of the scale of production and the region of presence. The comparative analytical model of the ecosystem was developed on the basis of the systematization of stakeholders and their indicators, the calculation and comparison of the values of which serve to assess the stakeholder configuration, the profile of a particular ecosystem. The potential of the analytical model of the ecosystem was tested on the information dataset of PJSC KAMAZ, JSC PO Yalamov Ural Optical and Mechanical Plant, PJSC Chelyabinsk Iron and Steel Works. The main result of the study was the understanding of the applicability, universality, instrumentality, illustrativeness of the analytical model of the company's ecosystem. In the course of the study, conclusions were drawn about the close, but not complete, binding of territories and ecosystems of firms. The theoretical and practical significance of the results lies in the refinement and successful testing of a universal tool for assessing ecosystems, which can be used both by business entities themselves and by public structures, public organizations, and rating agencies. A further direction in the development of the ecosystem approach may be a study of the agglomeration mission of firms' ecosystems.
After the West: Conrad and Nabokov in Long-Wave Literary History
Authors: Esty Jed
Published: December 2022

The Secret Agent and Lolita are among the most influential novels of the last century. Both describe European lodgers who insinuate themselves into nuclear families that serve as symbolic cocoons inside the most powerful nation-states on earth in 1907 and 1955, respectively. These two upmarket infiltration novels track an uneasy movement into the heart of Anglo-American darkness. Taken together, they also describe the arc of cultural capital traveling across the Atlantic. They orbit a myth of the stable West that can be neither disavowed nor dismantled. What can we learn now from the historical relation between these novels, set within the dilapidated metanarratives of Pax Britannica and the American Century? Is there a post-Western future for anglophone literary studies? To address those questions, this essay combines close formal analysis of Joseph Conrad and Vladimir Nabokov with a test run of current world systems and longue durée reading methods.

In response to the shortcomings of traditional concrete crack repair materials, a new generation of repair materials was developed – a microbial repair material (MRM) based on sodium alginate modification. A brushing technique is used to fix microorganisms on the cracks to be repaired so that they can deposit calcium carbonate (CaCO3) in situ to repair the cracks. The fundamental properties of the MRM were studied, along with the macroscopic morphology and surface water absorption of specimens before and after the repair of mortar cracks. The material changes and microstructure of the repair products were also analysed. The results showed that the calcium carbonate content, water absorption ratio and heating shrinkage rate of the MRM with modified sodium alginate were better than those of the repair material without microorganisms. It was also found that the microorganisms were fixed in cracks on the surface of the mortar using the brushing technique with sodium alginate as the carrier. They adhered tightly to the cracks after only two repairs and produced repair products (mainly calcium alginate and calcium carbonate) and the surface water absorption ratio was reduced by about 65% compared with that before repair.
Neuropsychological Assessment in The Forensic Context: A Scoping Review
Authors: Venturi da Silva Letícia , Cavalheiro Hamdan Amer
Published: December 2022

The introduction of neuropsychologists in legal practice allowed for the field of forensic neuropsychology to arise. However, it is still a recent field of knowledge that is in continuous development. The existing literature highlights the incipience of studies in this area and the need for adaptation of instruments and methods. Thus, this scoping review aims to analyze how neuropsychological assessment has been employed so far in the forensic context. In order to do this, a search and a follow-up were conducted in the databases PsycInfo, Scopus and Web of Science. The query used for both searches was "(neuropsychological assessment OR neuropsychological test)" AND "forensic" OR "forensic neuropsychology". Initially, 1001 papers were identified, and after a two-stage screening process, 83 articles were included for analysis. Regarding neuropsychological assessment, the most investigated constructs were cognitive levels, memory and symptom validity. The heterogeneity of employed instruments we found in the studies evidenced the great existing variability in forensic neuropsychological practice. Among the most assessed populations were individuals with psychiatric, psychological or neurological diagnoses and male adult detainees in general. With this review, we expect to provide an overview on the current state of forensic neuropsychology, as well as information that may serve as a starting point for new research and further developments in the field.

Some Legal Options to Ensure the Protection of South Africa's Utilisable Groundwater Resources
Authors: Viljoen Germarie , Bosman Carin
Published: December 2022

Groundwater, which is water that is found underground, is less susceptible than surface water resources to evaporation, and thus offers resilience against the impacts of climate change. Many South African cities, communities and farmers depend on groundwater for domestic or other socio-economic purposes. This implies that groundwater resources which are currently or potentially utilisable should be identified, and suitable legal measures should be implemented to protect these resources from potential risks of harm or damage posed by anthropogenic activity. This article firstly evaluates the effectiveness of the country's existing regulatory framework to effectively protect South Africa's groundwater resources and finds that the framework can be improved upon significantly. Secondly, it explores regulatory opportunities within the existing legal framework to strengthen South Africa's groundwater governance regime, including making use of land-use planning instruments to facilitate the implementation of groundwater protection zones.

Authors: Velásquez Vergara Sandra Milena , Moreno Fergusson María Elisa , Arroyave Álvarez Edgar Orlando , Cacante Caballero Jasmín Viviana
Published: December 2022

Objective. This work sought to describe the adaptation process by men to the nurse role.

Methods. Secondary analysis of data from a collective case study that had as participants 12 male nurses working in the city of Medellín, with ages between 28 and 47 years and average time of professional experience of 11 years. Information collection was carried out through in-depth interviews. The analysis was conducted through Roy’s Adaptation Model (RAM), reading of the interviews, identification of RAM’s components, grouping of fragments, assignment of tags, construction of a matrix and classification.

Results. The analysis performed accounts for the coping processes and adaptation by male nurses and the ineffective responses (control of emotions and emotional silencing) when practicing a role considered feminine.

Conclusion. In this study, it was possible to establish that, to achieve adaptation within nursing, men use strategies related with changes in bodily appearance, management of physical strength, and management of emotions.

Authors: Ocampo-Arenas María Camila , Parra-Zapata Mónica Marcela
Published: December 2022

En este artículo reportamos una experiencia de aula en modelación matemática para la educación primaria. La experiencia se orientó por la perspectiva socio-crítica de la modelación matemática y tuvo como propósito identificar cómo los y las estudiantes del grado primero (6-7 años) resolvían problemas ambientales por medio de la modelación matemática. Participaron 24 estudiantes de grado primero de una institución educativa de la ciudad de Medellín, quienes reflexionaron en relación con la contaminación generada por la práctica del consumo de pitillos y de las bolsas plásticas y plantearon soluciones para contribuir a la disminución de residuos a partir de la reutilización de dichos desechos. También identificamos que se usaron conceptos propios del grado de escolaridad, principalmente aquellos asociados al pensamiento numérico. Además de estos conocimientos, los resultados del análisis de esta experiencia informan sobre las posibilidades y maneras de desarrollar procesos de modelación matemática y de integrar contextos y problemas de la Educación Ambiental.

Objetivo: mapear as estratégias de desenvolvimento da competência de liderança de enfermeiros nos serviços de saúde. Método: revisão de escopo desenvolvida conforme proposto pelo Instituto Joanna Briggs. Estabeleceram-se como critérios de inclusão: artigos científicos originados de pesquisas de fontes primárias e secundárias, relatos de experiência, estudos de casos e artigos de reflexão com conteúdo completo disponível, sem restrição de idioma ou ano de publicação, que descrevessem estratégias para o desenvolvimento da competência de liderança direcionada aos profissionais enfermeiros nos serviços de saúde. Resultados: doze artigos compuseram a amostra, os quais apresentaram como estratégias os programas de desenvolvimento de líderes, os programas com foco no planejamento de sucessão, os processos de tutorias como o coaching e mentoring e a inovação. Conclusão: observou-se que, embora os estudos reconheçam a liderança de enfermagem como competência essencial para a prática profissional dos enfermeiros, poucos trazem estratégias de desenvolvimento, especialmente em serviços de saúde.
