Authors: Candela Dayana Trujillo- , Álvarez iceth N. Cuéllar , Garzón Francis S. Sánchez- , Nerio* Luz Stella
Published: April 2024

Arazá is an Amazonian fruit rich in carotenoids such as lutein, which has several biological properties. This paper evaluates the storage stability of lutein in microencapsulated arazá pulp by spray drying with maltodextrin as wall material. The physicochemical properties of the pulp and microencapsulation, encapsulation efficiency, percentage yield, thermal stability (DTG and TGA), morphology, particle size, storage stability and lutein degradation kinetic were evaluated. The results were low Aw (0.33), good yield (64.22%), spherical and smooth particles, the lutein degradation kinetic with a degradation constant of 1.49 × 10-4 days-1, which is thirty-five times lower than that obtained for the freeze-dried arazá pulp used as control. In conclusion, it was possible to obtain stable microencapsulates, being a promising alternative for the preservation of this perishable fruit.

Published: April 2024

El cuidado de personas autistas y con necesidades especiales relacionadas al neurodesarrollo, es un camino de altas exigencias y desafíos permanentes. Quienes se dedican a cuidar de estas personas necesitan soportes que les permitan ejercer autocuidado, así como oportunidades para seguir aprendiendo sobre un tema que conocen desde su experiencia. Reconociendo esta realidad, Fundación CAI creó desde Chile para Latinoamérica la Red on line de Cuidadoras y Cuidadores, con la finalidad de ofrecer espacios para el intercambio de saberes, información de interés y diálogo con especialistas, además de herramientas de autocuidado. Así la Red ha demostrado la importancia de la colaboración entre cuidadoras y cuidadores, profesionales especialistas y la ciudadanía en general. A través de Encuentros Temáticos, Programa de Autocuidado y el Consejo de Cuidadoras, se propone mejorar la calidad de vida de quien cuida y quien es cuidado. Así, este artículo propone discutir cómo el acceso y la participación en una red contribuyen a la inclusión y empoderamiento social, con base en la experiencia de la referida Fundación, donde participan miembros de la red de cooperación internacional para la educación e inclusión- GIEI. En base a esto será discutido el cuidado promovido en red más allá de las fronteras, donde la tecnología aproxima culturas, afectos y experiencias, ayudando a quienes muchas veces ejercen un cuidado solitario, doloroso y sin apoyo.

Published: April 2024

Introduction

Poor comprehension and medication adherence are common in older people, especially after hospitalizations, in case of changes or prescriptions of new therapeutic regimes. This randomized controlled trial aims to evaluate the effectiveness of an integrated approach in improving older individuals’ adherence to medical recommendations after hospital discharge.

Methods

Data from an expected sample of 360 older inpatients (and their caregivers) will be collected. Medical recommendations’ understanding will be tested before and after the routine explanation received by in-charge physicians. Participants will be randomized in the control (usual care) and intervention group. The intervention consists of educational training by a multidisciplinary team (occupational therapist, dietician, and physician, in consultation with a pharmacologist) at hospital discharge and, after hospital discharge, receiving a phone recall checking for therapy adherence and having the possibility to contact the study team for potential related concerns. After 7 days, medication adherence will be assessed through structured phone interviews comparing ongoing and prescribed medications and by administering the 4-item validated Morisky, Green, Levine scale and the Medication adherence report scale (MARS-5). At 30 and 90 days from discharge, data on medication adherence, falls, rehospitalizations, and vital status will be collected through phone interviews and hospital records.

Six-month pain and function outcome expectations were established for total knee arthroplasty using the smallest worthwhile effect
Authors: Riddle Daniel L. , Henderson Nancy
Published: April 2024

Introduction

Interpretations of patient-reported outcome measures following knee arthroplasty lack context and typically do not account for costs, risks and benefits compared to an alternative treatment. The primary purpose of our paper is to estimate expectations patients have for pain and function destination outcome, six-months following surgery relative to the outcome expected if knee arthroplasty was not done. Secondary purposes were to determine if statistically significant changes in the smallest worthwhile six-month outcome occurred following an interactive discussion and to assess the construct validity of the expected six-month outcome obtained at baseline.

Methods

This was a secondary analysis of a prospective longitudinal cohort study of 121 patients undergoing knee arthroplasty. Smallest worthwhile effect estimates were determined and expected six-month KOOS Pain and Function, daily activity measures were established during a pre-operative visit.

Results

The average six-month expected (the destination of interest) KOOS Pain score was 75 (IQR = 64 to 86) and the average KOOS Function, daily activity score was 74 (IQR = 59 to 86). The smallest worthwhile effect discussion led to significant changes in expected destination scores. For example, KOOS Pain expected outcome changed from 87.7 (9.8) to 75.0 (13.6), a statistically significant reduction in expected outcome (t(119) = 16.942, p < 0.001.

Conclusion

Six-month expected KOOS outcomes following knee arthroplasty were established and approximate the average six-month outcomes reported in the literature. Validity of these estimates was established. These data can be used to aid shared decision-making discussions regarding patient expectations of knee arthroplasty outcomes during a patient encounter.

Authors: Salum Shani S. , Kalabamu Florence S. , Fataki Maulidi R. , Omary Salha A. , Mohammed Ummulkheir H. , Kizwi Hillary A. , Leshabari Kelvin M.
Published: April 2024

Background

Hypoglycemia is the commonest metabolic abnormality encountered in newborns. Besides, there is a growing body of evidence that links the causes of early neonatal mortality to neonatal hypoglycemia in Tanzania. However exact factors associated with asymptomatic hypoglycemia in preterm newborns are not known.

Objective

To assess factors associated with asymptomatic hypoglycemia among preterm newborns.

Materials and methods

A cross sectional, analytical hospital- based study was carried out at Dar es salaam public regional referral hospitals. Preterm newborns with asymptomatic hypoglycemia were the target population. Data on demographic and clinical characteristics of preterm newborns and their mothers were collected and analyzed using Epi-Info™ software version 7.4. Main data analysis was done by applying a multivariable binary logistic regression model with neonatal random glycaemia coded in a binary fashion at a cut-off point of 2.6 mmol/L. An α-level of 5% was used as a limit of type I error.

Results

We recruited and analysed 217 preterm newborns within 6–24 hours post-delivery. Male: Female = 1.1:1 (females n = 105, 48.4%). Median glycemic level was 2.6 (IQR; 2.1–3.9) mmol/L. Median gestational age at delivery was 33 (IQR: 30–35) weeks. Breastfeeding within 1st hour post-delivery was a statistically significant factor against glycemic levels associated with hypoglycemia (OR; 0.123, 95%-CI; 0.052–0.287) in a fitted multivariable logistic regression model.

Conclusion

About half of all preterm newborns studied had glycemic values in a statistical range associated with hypoglycemia. Exclusive breast feeding within 1st hour post-delivery was associated with glycemic levels protective from risk of asymptomatic neonatal hypoglycemia.

Recommendations

Exclusive breastfeeding practices within 1st hour post-delivery may need to be emphasized to all expectant mothers in order to avoid potential risk of asymptomatic hypoglycemia in preterm newborns.
»Hands Across the Sea« - John Philip Sousa und der musikalische Amerikanismus in Kontinentaleuropa
Authors: Faßhauer Tobias
Published: April 2024

Der Dirigent und Komponist John Philip Sousa (1854-1932) war eine Ikone der amerikanischen Massenkultur um 1900. Seine Märsche und die internationalen Tourneen seines zivilen Blasorchesters machten ihn zu einem der bekanntesten Musiker seiner Zeit. Tobias Faßhauer zeichnet erstmals Sousas kontinentaleuropäische Konzertreisen nach, um seine Rolle im frühen Transfer amerikanischer populärer Musik nach Europa aufzudecken. Eingebettet in den Kontext der Debatte über Amerikanismus zu Beginn des 20. Jahrhunderts entsteht so ein luzides Bild von der Rezeption und dem Einfluss Sousas auf die europäische Musik.
Letting Go

My mom didn’t allow me to hold anything close. Not her or my dad. She bathed me in discomfort. Dried me in shame. Let me feel the uttermost of temperatures. I had to find footholds.

In the piece ‘Creative Non-Fiction: A Conversation’, we argued that ‘creative non-fiction has become in a sense “the genre” of South African writing, [...] writing which makes its meanings at the unstable fault line of the literary and journalistic, the maginative and the reportorial’ (2011: 57): recently, the work of Sihle Khumalo, Jacob Dlamini, Max du Preez, Rian Malan, Kevin Bloom, Denis Beckett, Shaun Johnson, Antjie Krog, Jonny Steinberg, Stephen Otter, John Carlin, Njabulo S. Ndebele, Jeff Opland, Julia Martin, Sarah Nuttall, Liz McGregor, Hedley Twidle, Duncan Brown; historically, Sol T. Plaatje, Can Themba, Nat Nakasa, Todd Matshikiza, Alan Paton, H. I. E Dhlomo, and many more. Perhaps more broadly, and recognising the important work of ‘Northern’ writers in this genre, we would argue that creative non-fiction has become a particularly significant genre of the global ‘South’, in which its imaginative engagement with ‘truth telling’ has been profoundly enabling in narrating pasts and presents characterised by injustice, inequality, division, and the need to ‘uncover’. It has also enabled writers to bring their own singular life and surroundings into an imagined narrative.
Patrick

Published: April 2024

Patrick had to go. I decreed it. I had allowed him to move into my garage one winter but then I evicted him. Not immediately, but after his tobacco and other noxious habits had begun to unsettle my equilibrium. Also, it was becoming unsanitary for reasons I’m sure I need not explain. I granted him refuge and then I ejected him. I sent him back to the streets, towards a world of bandits with no suburban carport for safe harbour. However, when I stood outside my house, arms akimbo for courage, I said nothing of my personal discomfort. In truth I said that I was worried about the way he struck matches and smoked while lying beneath my car. I recall no resistance, only mute acceptance. He left a bag of things – aging plastic packets, a woman’s wide-brimmed straw hat now lopsided and limp, food I’d given him days before. He’d return periodically to tell me he would be back the next day to remove it. Every ‘next day’ I circled his midden, noting how its contents had expanded: a shoe, a few more plastic bundles, food I’d given him the day before, an empty matchbox. Then quickly I walked away from its smell of Patrick. I was walking away from my own shame but, being the one more mute, knew not how to say it.
Multidimensional Poverty: Identification of Deprivation Characteristics of Papua's Population Poverty in 2020
Authors: Susanto Dedy , Wulandari Titis Setya
Published: April 2024

Papua is a growing province with rich potential yet has the highest rate of poverty and lowest rank of HDI in Indonesia. As poverty has been measured limited on monetary alone, anti-poverty programs and policies have become limited. Although the first goal of the SDGs clearly states that poverty is a multidimensional problem. Thus, measuring multidimensional poverty in Papua is needed. This study uses a multidimensional poverty formulation (MPI) with the 2019 Seychelles framework compiled by OPHI and the Seychelles National Bureau of Statistics in four dimensions: Decent Living Standards, Health, Education, and Employment. Considering data availability, not all indicators are available in the March 2020 SUSENAS data, so a four-dimensional approach in 13 indicators is carried out to calculate multidimensional poverty in Papua.As a result, the percentage of Papuans who experienced multidimensional poverty (H) was 71.2 percent, with the intensity (A) as 47.3 percent. The results show 0.337 points in MPI (M0), meaning that the average deprivation experienced by all residents in Papua Province is 33.7 percent of the 13 indicators from MPI. The dimensions with the most significant contribution are health (0.301), then employment (0.266), education (0.258), and a decent standard of living (0.175). Based on area classification, there is an imbalance between the contribution of multidimensional poverty at urban and rural levels with 0.220 and 0.780.This study found that Papuans experienced multidimensional poverty, the most deprived in the health dimension and indicators of school completion at least SMA or equivalent.
Ultrafine industrial aerosol as a risk factor for the health of smelting shop workers at a machine-building enterprise
Authors: Sharavara L. P. , Dmytrukha N. M. , Andrusyshyna I. M.
Published: April 2024

Aim. To evaluate the amount and physicochemical properties of ultrafine industrial aerosol (UIA) in the work zone air (WZA) of smelting shop workers at a machine-building enterprise during various technological processes (melting, welding, and metal machining).
Materials and methods. The physical properties of UIA particles were evaluated with NanoScan 3910 scanning spectrometer: the number of particles (number/cm3), particle surface volume (nm3/cm3), particle surface area (nm2/cm2), and nanoparticle mass concentration (μg/cm3) in the WZA of a furnace operator (n = 416), a welder (n = 315), a cutter (n = 286), a grinder (n = 78), and workers of the control group (n = 315). The chemical composition of the air samples was determined by inductively coupled plasma optical emission spectrometry (ICP-OES) using an Optima 2100 DV device.
Results. It has been found that the highest concentration of UIA nanoparticles was recorded during metal melting at the workplaces (WP) of furnace operators (4.28 × 104 to 2.41 × 105 particles/cm3) and welders (3.01 × 104 to 3.34 × 105 particles/cm3). During mechanical metal processing, a much smaller number of nanoparticles was produced (for grinders, the number varied from 9.81 × 104 to 1.44 × 105 particles/cm3; for cutters, it varied from 2.71 × 104 to 1.94 × 105 particles/cm3). Indicators of surface area, surface volume and mass concentration at the WPs of furnace operators, welders, grinders and cutters exceeded the corresponding indicators of the control group for almost all sizes of suspended particles with statistically significant differences (p ≤ 0.05). It has been estimated that such metals as Al, Cu, Mg, Mo, Fe, and Ni were present in the workers’ WZA but their content did not exceed the current maximum permissible concentrations.
Conclusions. The presence of suspended particles of UIA with a maximum concentration in the range from 20 nm to 70 nm has been confirmed in the WZA during melting, welding of metals and machining. Indicators of concentration, surface area, surface volume, and mass concentration at the workplaces of melting shop workers at the machine-building enterprise significantly exceeded the corresponding indicators in the control group without dust formation processes, showing statistically significant differences (p ≤ 0.05). The evidence of metals in the WZA has suggested their presence in the form of nanoparticles, which are more active and dangerous, thus increasing the risk of their adverse effects on the workers.

Published: April 2024

Objectives

Accurate measurements of renin and aldosterone levels play an important role in primary aldosteronism screening, which is of great importance in the management and categorization of hypertension. The objective of this study is to investigate the current status of plasma renin and aldosterone measurements in China, which is achieved by analyzing the results of 526 clinical laboratories nationwide for three pooled fresh plasma samples derived from more than 2,000 patients.

Methods

Renin and aldosterone in three pooled plasma samples were measured four times in 526 laboratories employing various measurement systems. The inter- and intra-laboratory %CV were calculated and compared. To determine the source of the substantial inter-laboratory %CV, laboratories were categorized according to the measurement systems they are using, and both the inter- and intra-measurement-system %CV were calculated and compared.

Results

Regarding renin, the majority of laboratories use four primary commercial immunoassays. However, for aldosterone, in addition to commercial immunoassays, laboratory-developed liquid chromatography-tandem mass spectrometry (LC-MS) methods are also used by laboratories. The median values of intra-laboratory %CVs, intra-measurement-system %CVs, inter-laboratory %CVs, and inter-measurement systems %CVs varied between 1.6 and 2.6 %, 4.6 and 14.9 %, 8.3 and 25.7 %, and 10.0 and 34.4 % for renin, respectively. For aldosterone, these values ranged from 1.4 to 2.2 %, 2.5–14.7 %, 9.9–31.0 %, and 10.0–35.5 %, respectively.

Conclusions

The precision within laboratories and measurement systems for plasma renin and aldosterone measurements is satisfactory. However, the comparability between laboratories using different measurement systems remains lacking, indicating the long way to achieve standardization and harmonization for these two analytes.
Inconsistency between the micropolar theory and non-equilibrium thermodynamics in the case of polar fluids
Authors: Stephanou Pavlos S.
Published: April 2024

The balance equation of angular momentum in anisotropic fluids includes a couple stress contribution, also responsible for an antisymmetric contribution to the force stress tensor. We herein derive all balance equations for the simplest anisotropic fluid, i.e., a polar fluid, using the GENERIC formalism of non-equilibrium thermodynamics. In doing so, we find that there is an inconsistency between the internal energy density evolution equation derived using non-equilibrium thermodynamics and the one usually considered in micropolar theory.
Enhancing the structural performance of engineering components using the geometric mean optimizer
Authors: Mehta Pranav , Yildiz Ali Riza , Sait Sadiq M. , Yildiz Betül Sultan
Published: April 2024

In this article, a newly developed optimization approach based on a mathematics technique named the geometric mean optimization algorithm is employed to address the optimization challenge of the robot gripper, airplane bracket, and suspension arm of automobiles, followed by an additional three engineering problems. Accordingly, other challenges are the ten-bar truss, three-bar truss, tubular column, and spring systems. As a result, the algorithm demonstrates promising statistical outcomes when compared to other well-established algorithms. Additionally, it requires less iteration to achieve the global optimum solution. Furthermore, the algorithm exhibits minimal deviations in results, even when other techniques produce better or similar outcomes. This suggests that the proposed approach in this paper can be effectively utilized for a wide range of critical industrial and real-world engineering challenges.

Challenges in the solution phase synthesis of PSMA-11 and PSMA-617: organic ligands for radiopharmaceutical preparations in prostate cancer medication
Authors: Kumar K. S. Ajish , Mathur Anupam
Published: April 2024

Patient specific treatments for different cancers are currently being actively addressed through nuclear medicine. More recently, the identification of biomarker namely; prostate-specific membrane antigen (PSMA) expressed on the prostate cancer cell surface has been considered as a turning point in prostate cancer management using radiopharmaceuticals. In this treatment method, apart from radionuclide, organic ligands that target PSMA constitute an essential component. PSMA-11 and PSMA-617 are two important ligands that form the radiopharmaceuticals, [68Ga]Ga-PSMA-11, [177Lu]Lu-PSMA-617, which are currently powering the prostate cancer management, especially metastatic castration resistant prostate cancer (mCRPC) in most part of the world. Identification of efficient synthetic routes towards these highly expensive ligands is an important prerequisite to make this treatment modality more popular. In this account, the synthetic challenges that we circumvent during the solution phase synthesis of PSMA-11 and PSMA-617, through different chemical synthetic routes are demonstrated. Post-synthesis, both the ligands, PSMA-11 and PSMA-617 were successfully radiolabelled using 68Ga, and 177Lu, respectively, to generate corresponding labelled products [68Ga]Ga-PSMA-11, and [177Lu]Lu-PSMA-617, in good radiochemical purity.

This study aimed to examine the mechanical and physical characteristics of hybrid composite prepared using bio-epoxy reinforced with natural fibers extracted from pineapple leaf (PLF) and sisal (SF). The hand lay-up technique was utilized to fabricate the hybridized composite from bi-directional pineapple leaf fiber and sisal fibers using various stacking sequences. In order to understand the impact of hybridization on these composites, physical properties including density, percentage volume of fiber (PVF), and water absorption capacity were ascertained for hybrid composite. In addition, the mechanical characteristics like the tensile, fracture toughness, flexural, and interlaminar shear (ILSS) tests were investigated. Poly(furfuryl alcohol) was prepared and used as bioresin and it was apparent that the addition of more PLF in terms of PVF into hybridized composites, the properties flexural, tensile, and ILSS of the bio-epoxy composites were notably improved. The mechanical properties of hybridized composites were markedly impacted by the stacking order. Inference revealed that the composite attained the maximal tensile strength of 70.8 MPa for alternative sequence of SF and PLF. The composite which contained SF on the outside, had outperformed compared to other hybrid composites in terms of fracture toughness (3302.3 J/m2) and interlaminar shear strength (16.1 MPa).

The perception on physical activity among students
Authors: Leuciuc Florin Valentin , Pricop Gheorghe
Published: April 2024

Background and Study Aim. Questionnaires are useful tools for assessing the level of physical activity in the general population due to their brevity, ease of understanding, and ease of application. The aim of our study is to subjectively assess the physical activity of participants using the self-report scale of the Godin–Shepard Leisure-Time Physical Activity Questionnaire.
Material and Methods. The study involved 299 undergraduate and graduate students from Stefan cel Mare University of Suceava (Romania). In their academic activities, they typically engage in between 4 and 6 hours of practice. Additionally, many respondents participate in various physical activities, totalling another 4 to 8 hours of physical activity per week. The questionnaire consists of three questions regarding the level of physical activity (intense, moderate, low). It aims to collect data for the past 7 days for each physical activity lasting at least 15 minutes.
Results. The intergroup analysis of the data showed statistical significance in the Wilcoxon rank-sum test for three out of six analyzed situations: graduate males versus graduate females, undergraduate males versus undergraduate females, and graduate males versus undergraduate males (p < 0.001). In the study, data concerning the level of physical activity among students were collected. Data analysis showed that over 80% (240 out of 299) of the respondents are moderately active or active. Statistically significant differences were observed only by study level and gender. While there was a notable difference of 10 points between males and females, it did not reach statistical significance.
Conclusions. We can conclude that physical activity is an important aspect of students' daily routines. However, awareness programs are necessary to encourage them to remain physically active. These programs also promote the benefits of physical activity for physical, mental, and social well-being, as well as overall quality of life.

Published: April 2024

Background and Study Aim. The aim of this study was to examine the effect of a 6-week plyometric training program on agility, vertical jump, squat jump, and speed performance in soccer players.
Material and Methods. A total of 26 male soccer players actively playing for Ankara Batıkent Kartal Sports Club participated in the study as volunteers. The players had an average age of 15.04 ± 0.16 years, an average height of 172.48 ± 5.14 cm, and an average body weight of 62.65 ± 0.38 kg. Data on the players' gender, age, body weight (kg), height (cm), body mass index (BMI), agility, vertical jump (cm), squat jump, and 30 m speed were obtained. Statistical analysis was performed using SPSS 25 software. The normality of the data was examined using the Shapiro-Wilk test. Paired samples t-test was used to determine within-group differences, and independent samples t-test was used to determine differences between groups. A statistical significance level of p < 0.05 was considered for all evaluations.
Results. The plyometric training program was effective in improving agility, vertical jump, squat jump, and speed performance in the experimental group. There was a significant difference in agility and 30 m speed values in the pre-test and post-test evaluations of the Control group, but no difference was observed in vertical jump and squat jump values. Additionally, in the pre-test and post-test comparison between the experimental and control groups, a significant difference was observed in agility, vertical jump, and squat jump values. However, no significant difference was found in 30 m speed values.
Conclusions. That plyometric training program  is effective in improving agility, vertical jump, squat jump, and 30 m speed values.

Published: April 2024

The mixed convective flow of Ree-Eyring ternary-hybrid nanofluids over a static wedge, incorporating the Cattaneo-Christov (C‐C) model was investigated to examine the fluid's heat and mass transfer characteristics. The novelty lies in using ternary-hybrid nanofluids comprising TiO2, Al2O3, and Ag nanoparticles in water. The significance lies in potentially enhancing heat transfer efficiency and fluid dynamics control in various engineering applications. The research methodology involves mathematical modeling of the flow and heat transfer equations, transformation of partial differential equations into ordinary differential equations, and numerical solution using the bvp4c method in MATLAB. The skin friction, Nusselt and Sherwood numbers, entropy generation rate, and Bejan number are investigated for the different values of the governing parameters through graphs. The study concludes that ternary-hybrid nanofluids exhibit superior heat transfer properties compared to traditional fluids, with significant potential for heat exchangers, cooling systems, and energy generation applications. Additionally, there is an observed increase in skin friction, heat transfer rate, and mass transfer rate when transitioning from a flat plate to stagnation point flow and from Newtonian to non-Newtonian nanofluids.
Spectres of Black Flags in the Miombo: The Islamic State's coverage of their Mozambique province, 2022-2023
Authors: Hansen Stig Jarle , Bary Ida
Published: April 2024

This article studies the Islamic State's only remaining periodical, Al-Naba, identifying the most common tropes and patterns in the periodical's Sub-Saharan Africa coverage, and on Mozambique in particular. The Islamic State's increasingly important coverage of Africa focuses on terror attacks, military campaigns and on the fight against Christianity. However, it also employs more traditional anti-colonial arguments that have been used by other, more accepted, political actors during the struggle for decolonisation. Al-Naba also functions as a 'shamer' of non-African Muslims, to get them to join jihad by pointing to the African successes of the organisation and set these successes up as examples to be followed. In this sense, the article illustrates how African jihadist branches can have global agency.

Julka Chlapec Ðorđević’s New Woman
Authors: Milinković Jelena , Svirčev Žarka
Published: April 2024

The paper presents the concept of the new woman by Julka Chlapec Đorđević (1882–1969) as an intersectional figure between the different lines of the writer’s feminist thought and social engagement. We dedicate the first part of the paper to the theoretical basis of this concept. In the second part, we analyze the modes of its formation in Chlapec Đorđević’s writing. Our research focused on her discursive formulation of the new ethics and politics of sexuality and the related private/public micro-institutions of patriarchy as basic frameworks within which she articulated the concept of the new woman. Chlapec Đorđević comprehensively realized the concept of the new woman in the novel Jedno dopisivanje [A Correspondence] (1932). We depict its heroine as a paradigm of the writer’s theoretical thought on the emancipated woman in correlation with many modern phenomena.

Authors: Campos Edison , Jimenez Luis , Once Santiago
Published: April 2024

The moorland or paramo is a threatened ecosystem. The indiscriminate advance of the agricultural frontier is producing the loss of ecosystem services, especially water service. This research estimated the willingness to pay (WTP) of the water users corresponding to the Municipality of Riobamba for the conservation of 3 ecosystem services: water service, soil conservation and scenic beauty of the Chimborazo Fauna Production Reserve (RPFCH). Four hundred and six surveys were applied by means of the double limit dichotomous contingent valuation method, using a maximum likelihood model in the Stata software. Four models were developed: simple limit, simple limit with other explanatory variables, double limit, and double limit with other explanatory variables, the latter being statistically more significant. As a result, it was determined that the WTP for the ecosystem service of water production is USD 0.84, for soil conservation USD 0.88 and for scenic beauty USD 0.81 per month that they would be willing to pay for the care of these services.

Objectives. The study aimed to assess the impact of football training, particularly for goalkeepers, on children’s motor skills and aerobic capacity over a 10-month period.
Materials and methods. This experimental study focused on evaluating the specific skills of goalkeepers and the aerobic capacities of children who took on the role of goalkeeper after undergoing training. The study involved totally 20 individuals aged 10-14 who played as goalkeepers and who were part of the entire population trained at the Real Madrid Foundation UNY Football School. The changes in the goalkeeperʼs aerobic capacity, reaction speed, and diving, as well as anthropometric measurements were found in the study. The instruments used for this research included a multi-stage fitness test, a test of the goalkeeperʼs reaction and diving skills, as well as height and weight measurements. The data analysis technique used was the t-test to determine differences in variables between the pretest and post-test, with a significance level of less than 0.05 (P < 0.05).
Results. The results revealed significant improvements in aerobic endurance (P = 0.004), reaction ability (P = 0.007), and goalkeeper diving (P = 0.002) after 10 months of football training. However, there were no significant changes in height, weight, and BMI, as the P value was greater than 0.05.
Conclusions. These findings have important implications for evaluating goalkeeper training programs and provide a basis for recommending more effective ones.

Objectives. The purpose of the study was to substantiate the influence of physical activity on stress-associated conditions in higher education students.
Materials and methods. The dataset for building the models consisted of 1115 observations, 16 independent and 3 dependent variables. As the main method we used the random forest method, the idea of which is to obtain a forecast by aggregating the predictions of a set of individual decision trees, each of which is trained on a data subset isolated from the studied sample.
Results. Physical activity (PA) was found to be the most important factor in predicting stress-related conditions in university students. In addition, PA levels involving moderate and high levels of energy expenditure, as well as the number of stressful events experienced, played a significant role in predicting stress among students. In order to predict stress-related conditions in higher education students, the models “Stress”, “Increased anxiety”, and “Risk of PTSD” were built using the random forest method. The model “Stress” had the highest quality: its Accuracy was 0.77, Recall – 0.86, Precision – 0.79, and F1 Score – 0.82. The “PTSD Risk” model correctly predicted 78% of cases that indicates its good overall performance, however it correctly identified only 23% of the students who actually had the signs of this disorder. Regarding the state of anxiety, given that it is less stable than stress and PTSD, which can make model training difficult, the model built had an average accuracy of 56%, as well as reduced completeness and balance.
Conclusions. Models for predicting increased anxiety and identifying students with signs of PTSD require further improvement. The implementation of developed models allows to quickly identify the manifestations of stress-related conditions in higher education students and to take the necessary measures based on the engagement in PA to prevent the development of stress-related disorders.
