Objectives

To investigate changes in risk of infection and mental distress in healthcare workers (HCWs) relative to the community as the COVID-19 pandemic progressed.

Methods

HCWs in Alberta, Canada, recruited to an interprovincial cohort, were asked consent to link to Alberta’s administrative health database (AHDB) and to information on COVID-19 immunization and polymerase chain reaction (PCR) testing. Those consenting were matched to records of up to five community referents (CRs). Physician diagnoses of COVID-19 were identified in the AHDB from the start of the pandemic to 31 March 2022. Physician consultations for mental health (MH) conditions (anxiety, stress/adjustment reaction, depressive) were identified from 1 April 2017 to 31 March 2022. Risks for HCW relative to CR were estimated by fitting wave-specific hazard ratios.

Results

Eighty percent (3050/3812) of HCWs consented to be linked to the AHDB; 97% (2959/3050) were matched to 14,546 CRs. HCWs were at greater risk of COVID-19 overall, with first infection defined from either PCR tests (OR=1.96, 95%CI 1.76–2.17) or physician records (OR=1.33, 95%CI 1.21–1.45). They were also at increased risk for each of the three MH diagnoses. In analyses adjusted for confounding, risk of COVID-19 infection was higher than for CRs early in the pandemic and during the fifth (Omicron) wave. The excess risk of stress/adjustment reactions (OR=1.52, 95%CI 1.35–1.71) and depressive conditions (OR=1.39, 95%CI 1.24–1.55) increased with successive waves during the epidemic, peaking in the fourth wave.

Conclusion

HCWs were at increased risk of both COVID-19 and mental ill-health with the excess risk continuing late in the pandemic.

La energía es un recurso clave para el desarrollo de la sociedad moderna, por lo que la necesidad de fuentes de energía renovables es urgente. Aunque Brasil se encuentra entre los países con la matriz energética más limpia, las regulaciones relativas a la generación y distribución (GD) de energía aún son insuficientes. Así, el objetivo de esta investigación fue analizar los principales cambios instituidos por la Ley 14.300/2022 y sus impactos en el consumidor en comparación con la resolución normativa nº 482/2012 de ANEEL. La investigación se desarrolló a través de un estudio cualitativo con enfoque exploratorio descriptivo a través de una revisión de literatura y análisis comparativo entre la nueva ley 14.300/2022 y la REN 482/2012. Es una investigación importante, pues al tratarse de un cambio normativo reciente, existen pocos estudios publicados sobre el tema. La nueva Ley trae cambios significativos para el sector eléctrico brasileño, entre ellos: la eliminación del cobro de tarifa mínima y la creación del modelo de compensación por energía inyectada en la red. Sin embargo, aún quedan desafíos por enfrentar para que la GD se consolide en Brasil. Este estudio contribuye a la comprensión del marco regulatorio de la GD de energía y ayuda a llenar el vacío de estudios comparativos entre diferentes regulaciones relacionadas con el tema. Además, contribuye a la comprensión de los impactos sociales y ambientales de la adopción de sistemas de GD en Brasil, al resaltar los beneficios y desafíos de la transición a un modelo de generación de energía más limpio y sostenible, proporcionando subsidios para la formulación de más políticas públicas efectivas en la materia.

In this study, the relationship between classroom teachers' professional commitment and career satisfaction was analysed. The research was conducted using relational survey model. The data were obtained with career satisfaction scale, professional commitment scale and information form for classroom teachers. The research was limited to the 2022-2023 academic year. The sample of the study is 290 classroom teachers working in public schools in different cities of Turkey. The data were analysed using ANOVA, t-test, correlation and regression tests. According to the results of the analyses, it was seen that there was a significant difference in the professional commitment of classroom teachers in terms of gender, years of service, place of work and educational status variables. It was concluded that career satisfaction of classroom teachers did not show a significant difference in terms of gender, years of service and place of work variables, but showed a significant difference in terms of educational status variable. It was found that there was a moderate, positive and significant relationship between professional commitment and career satisfaction of classroom teachers. According to the results of the regression analysis, it was determined that approximately 22% of the change in career satisfaction was explained by professional commitment. The findings obtained in the study were discussed and some suggestions were made on the subject.

Published: January 2024

Game-based learning has gained increasing attention globally. It is an effective pedagogical approach to promote students’ engagement and improve learning outcomes. However, the literature reveals there is a need to strengthen game-based learning, as many students retain only fun of academic games. This study aimed to explore students’ experiences on the integration of debriefing in game-based learning at an identified higher education institution in South Africa. The social constructivism theory was utilised as a theoretical lens in this study. The authors employed a qualitative single case study design within an interpretivist paradigm. A purposive sampling strategy was adopted. Six participants were recruited for this study. Data were analysed inductively using thematic analysis. The findings of this study revealed that participants shared positive views and attitudes towards debriefing in game-based learning. They believed game-based learning significantly promoted their studies. The implementation of debriefing in game-based learning assisted them to identify their strengths and weaknesses. Furthermore, the utilisation of debriefing in game-based learning enhanced collaborations and teamwork. This study also highlighted that there was a need to ensure that debriefing was well planned in advance, and that instructors should be competent to conduct debriefing sessions. This study concluded that debriefing is an effective method to advance game-based learning. Further research should be conducted at national and international levels with different research approaches.

Results of Sn/Pb solder affected aluminum under wear study
Authors:   Innovation Centre, International University of Business Agriculture and Technology, Kaiser Mohammad Salim
Published: January 2024

Nanostructured Al-Sn and Al-Pb alloys are effectively used to improve their wear characteristics. Taking this into consideration, the wear properties of aluminum have been studied while affected by both elements Sn-Pb solder at a lower level to explore its reusing potentials. In this purpose a common pin-on-disk device is used in which different dry, wet and corrosive sliding environments are applied. Additionally, pure Al, Al-Sn and Al-Pb alloys are also considered for recovering the clarification and to separate elemental effects on wear properties. The worn surfaces of the samples are examined using optical and scanning electron microscopy, both before and after wear. Surface roughness also is a measure to assess the wear properties under different environments. The findings revealed that minor solder has a great impact on the wear properties of Al with Sn playing a better role than Pb. Solid solution strengthening is the main reason for improved wear behavior in terms of the low wear rate and coefficient of friction. Both Sn and Pb do not form any intermetallic with Al but with impurities it can easily occur particularly with Sn resulting in better wear properties. This phenomenon is more prominent in corrosive environment than wet due to the protective oxide layer on the surfaces. In dry sliding conditions, numerous large wear particles, oxide debris and grooves can be seen on the worn surface, but smoother wear tracks are seen in wet and corrosive environments as form oxide film and thumbs down somewhat direct contact on the moveable surfaces. SEM analysis also reveals higher abrasive wear and plastic deformation on the worn surface produced under dry sliding conditions where minor added alloys indicating that reinforcing particles effectively influence the properties.

Compound Conway-Maxwell Poisson Gamma Distribution: Properties and Estimation
Authors: Merupula Jahnavi , V S Vaidyanathan
Published: January 2024

The distribution of a random sum of random events is called a compound distribution. It involves a counting (discrete) distribution to model the number of occurrences of the random event in a fixed time period and a continuous distribution to model the outcome of the random event. It has applications in the fields of actuarial sciences, meteorology etc. For example, in modelling insurance loss amounts through compound distributions, the number of claims and the claim amounts are used to calculate the total claim amount of a portfolio. The number of claims is modelled through a discrete distribution and the claim amounts are modelled through continuous distributions. Generally, Poisson distribution is used in compound models as the discrete distribution and such models are known as compound Poisson models. However, the equi-dispersion property of the Poisson distribution hinders its application in scenarios where the underlying count data is either over- or under-dispersed. In this paper, a two-parameter Poisson distribution, namely, Conway-Maxwell Poisson (CMP) distribution, which handles both over- and under-dispersed data, is considered as the counting distribution, and the corresponding compound CMP distribution is developed. Some mathematical properties of the distribution are derived and a methodology to estimate the parameters using the likelihood approach is proposed. A numerical illustration of the proposed methodology is given through a simulation study. An application of the compound CMP model is illustrated through transportation security administration (TSA) insurance claim data. Also, the estimation of the risk measures associated with the TSA claim data is discussed.

B a c k g r o u n d . In recent years, Ukraine has experienced an unfavorable epidemiological situation concerning sexually transmitted diseases. One rapidly spreading infection is genital human papillomavirus (HPV). Convincing research has identified human papillomavirus (HPV) as a significant factor in the development of malignant transformations in the cervix. The study of the molecular pathogenesis associated with HPV-related neoplasms has led to the discovery of biomarkers aiding in the diagnosis of High-grade Squamous Intraepithelial Lesion (HSIL) of the cervix. Including the biomarkers p16/Ki-67 in the investigation enhances sensitivity in detecting HSIL in women. Additionally, it is pertinent to further analyze the effectiveness of using an additional semi-quantitative scale to assess the results of immunocytochemical detection of p16/Ki-67. M e t h o d s . The research was conducted on biological material from cervical smears using liquid-based cytology. Techniques included Papanicolaou staining, HPV detection, and immunocytochemical staining against p16/Ki-67. The sample comprised 90 women divided into three age groups, each categorized based on criteria such as HPV presence/absence, Bethesda classification of dysplasia, and negative/positive p16/Ki-67 results. Intensity of staining was further scored on a scale in the corresponding location of positive reactions in the nucleus or cytoplasm. R e s u l t s . The study revealed that immunocytochemical markers p16 and Ki-67 identified women with intraepithelial lesions, especially in cases with positive HPV results and no dysplastic changes in the Pap test. The intensity of immunocytochemical staining for p16 and Ki-67 varied directly with the detected degree of dysplasia. C o n c l u s i o n s . A direct correlation was observed between the severity of dysplasia established by Bethesda classification and the intensity of immunocytochemical staining for p16 and Ki-67. These findings provide an opportunity for further exploration of staining intensity in the presence of immunocytochemical markers p16 and Ki-67 for their potential use in the comprehensive interpretation of Pap test results and the precise identification of dysplasia in ambiguous diagnostic samples.

B a c k g r o u n d . Monitoring of ecosystems affected by military actions is an element of a comprehensive assessment of the state of the ecosystem in the post-war period. The results of this study are key for the post-war recovery of the war-affected region and assessment of the state and quality of water resources in the area for their further use, as well as for the assessment of the consequences of Russian armed aggression for local water ecosystems and the hydrological network of the region in general. In February-March 2022, the Kozarovytska dam was blown up, which caused flooding of the floodplain more than 20 km downstream. M e t h o d s . As a result of the flooding of agricultural lands, the waters of the Irpin River were polluted with products of human life (burial sites, cattle cemeteries, village toilets, places where livestock and birds are kept, fertilizers, decay products of plant remains) and flooded military equipment and ammunition. The purpose of this work is to study the zooplankton and ichthyofauna in the Irpin River and its tributaries the Moschunka and the Gorenka rivers. The study was conducted in the summer of 2023. A conical plankton net was used for zooplankton sampling. Quantitative parameters of zooplankton were determined according to Hensen's computational method in Bogorov's chamber using binoculars. R e s u l t s . Determination of the saprobiological state of the investigated water bodies was carried out according to the Pantle-Bucca method. Ichthyological samples were taken using a dip bag. During the experimental period, 10 species of zooplankton were found, which included rotifers, cladocera and copepods, and 3 species of fish. C o n c l u s I o n s . The obtained results indicate a significant decrease in the species richness of zooplankton in the studied reservoirs in comparison with last year's indicators, which can be explained by the consequences of anthropogenic load on the studied water ecosystems during the phase of active military operations within the Buchansky district.

AIM: of the study was to evaluate the clinical and genetic characteristics, including the development of adverse events and outcomes in patients with catecholaminergic polymorphic ventricular tachycardia (CPVT).
MATERIALS AND METHODS: The clinical phenotype of eight patients with CPVT, two of whom were relatives of probands, was observed over 4 years. The clinical and instrumental study included ECG-12, 24-hour Holter ECG monitoring, genealogical history collection and family history of sudden cardiac death (SCD), transthoracic echocardiography and cardiac magnetic resonance imaging to detect structural myocardial changes, electrophysiologic study according to indications, and ICD monitoring. High-throughput sequencing (NGS) was utilized to search for mutations in genes linked to the onset of channelopathies and other inherited rhythm disorders.
RESULTS: In 8 patients, nucleotide variants of pathogenicity classes III-V were identified according to the ACMG (2015) criteria in the RYR2 gene associated with CPVT. Pathogenic (IV-V class) and likely pathogenic (IV class) mutations in the RYR2 gene were found in 6 (75%) probands, variants with uncertain clinical significance (VUS, class III) were found in 2 patients. At the time of diagnosis, transient QTc interval prolongation of more than 480 ms was detected in 4 (50%) patients; bradycardia less than 54 beats/min — in 2 (25%) patients, sequences of supraventricular tachycardia and ventricular tachyarrhythmia — in 2 (25%) patients. The most severe form of the disease with marked clinical manifestations and an episode of clinical death with subsequent resuscitation, as well as a transient QTc interval prolongation exceeding 500 ms was observed in patients with mutations c.11814C A (p.Ser3938Arg, rs794728704); c.463G A (p.Gly155Arg) and c.14876G A (p.Arg4959Gln, rs794728811) in the RYR2 gene. Three (37.5%) patients underwent ICD implantation; one for primary SCD prevention and two for secondary prevention.
CONCLUSION: In this study, the spectrum of clinical manifestations in patients with genetically confirmed CPVT was examined. The findings highlight transient QTc interval extensions, significant sinus bradycardia, and sequences of supraventricular tachyarrhythmias, which can escalate into life-threatening ventricular tachyarrhythmias in CPVT patients.
Origins of the development of systems for the provision of medical care to maxillofacial wounds and the training and advanced training of military dentists
Authors: Iordanishvili Andrey K.
Published: January 2024

The purpose of the article is to highlight the origins of the development of systems for providing medical care to the maxillofacial wounded, training and advanced training of military dentists, which have not been discussed in modern specialized literature. The basis for the preparation of the article is the analysis of the Russian specialized literature on maxillofacial surgery and dentistry, as well as historical publications on these disciplines.
The development of systems for the provision of medical care to the maxillofacial wounded, training and advanced training of military dentists, carried out under the auspices of the Department of Dentistry of the Military Medical Academy, allowed in 1940 to adopt a unified military doctrine on the provision of medical care to the maxillofacial wounded. The leading role in this belonged to the Leningrad team of dentists and maxillofacial surgeons, headed by Professor D.A. Entin, whose employees have done a lot of work to help the maxillofacial wounded, both in combat conditions and in the rear. Thanks to scientific and applied activities of the staff of the Department of Dentistry of the Military Medical Academy, the work of maxillofacial surgeons and dentists during the Great Patriotic War of 1941–1945 was effective and fruitful.

Published: January 2024

BACKGROUND: The three-dimensional (3D) space of a virtual articulator requires precise adjustment considering individual parameters for the precision work of orthopedic dentists, orthodontists, and dental technicians. A modern solution that includes a virtual articulator is the domestic Avantis 3D software, which simplifies and speeds up functional diagnostics by creating a 3D scene of the patient.
AIM: To compare a repeatability of articulation parameters obtained when adjusting the domestic virtual articulator Avantis 3D using laboratory and intraoral scans of terminal positions of the lower jaw.
MATERIALS AND METHODS: A group of 30 volunteers aged 18–35 years participated in this study. The group consisted of 18 women and 12 men. Each participant underwent a computed tomography of the maxillofacial region, including the temporomandibular joint region in a state of habitual occlusion; one-stage A-silicone impressions were obtained, plaster models were cast, and silicone bite registers of three terminal positions were made. An intraoral scan of the upper and lower jaws was performed, and optical bite scans were obtained in the position of maximum fissure-tubercle contact and in the terminal positions of the lower jaw, fixed by previously obtained silicone registers. The same protocol was conducted for plaster models of the patient’s dentition and silicone registers of terminal positions. Using intraoral scans, optical recorders of terminal positions and computer tomograms in the Avantis 3D program and 3D scenes were created, and a virtual articulator was configured.
For each patient, the virtual articulator was adjusted in the Avantis 3D software, seven times using data from the intraoral scanner level and seven times from the laboratory level.
The reproducibility of articulatory parameters was assessed for all types of scans obtained, examining the standard and individual intercondylar distances for each patient.
RESULTS: The average values of the standard square deviation of articulatory parameters obtained when creating 3D scenes using laboratory scans at individual and standard intercondylar distances were higher than the similar values obtained using intraoral scans.
CONCLUSION: The accuracy of creating a virtual copy of a patient can be influenced by several factors: the error in combining scans, repeated scanning, the error in combining scans and computer tomograms, the error in combining jaw and bite scans, and the presence of penetrating occlusal contacts between scans of the dentition.

Published: January 2024

Economic growth has several determinants, however, there is little research on the effect of income inequality on economic growth. In the case of the European Union, there are countries with different varieties of capitalism, which leads a significant variation in the levels of inequality between countries. The paper aims to estimate the effect of income inequality on the economic growth of the Member States of the European Union, considering different types of income inequality: Gini index, top 1% share and top 10% share. We used a dynamic and static panel that models which measure the effect of inequality on the economic growth of the Member States of the European Union. The results show that the type of inequality variable affects the relationship between the income inequality and economic growth, in addition to the fact that the indicators that measure income inequality have a negative and positive impact on the economic growth on the Member States of the European Union.

Every organization faces organizational changes during its existence. Changes in customer needs, emergence of new competitors, new technologies, availability of limited resources, economic and social trends are just some of the reasons why organizations have to adapt their strategies, structure, culture, technology and people (their skills, knowledge, habits…). Human resources are most valuable asset and therefore require to be carefully managed through the process of change implementation. This is a prerequisite for an organization to be successful in the contemporary environment. Changes generate stress for all members of the organization which in return affects the quality of work, behaviour and engagement. The purpose of this paper is to examine characteristics of managing changes and stress in Croatian enterprises from the perspective of the employees and managers. The results of the study conducted on a sample of 102 respondents show that organizations mostly operate in dynamic environment which reflects the necessity for continuous implementations of changes whether they are adaptive or innovative. More than 60% of the respondents perceive change as a positive process even though almost half of them regard resistance to change in their organizations to be moderate. Results from the simple linear regression also confirmed that change and stress management strategies have an effect on the level of resistance to change.

Authors: Sharan Sneha , Aeran Himanshu , Tuli Amrinder Singh
Published: January 2024

: Aim of the study was to determine the adjunctive role of subgingival irrigating solutions i.e., ozonated water, 0.2% chlorhexidine and 5% Povidine Iodine in Phase-I periodontal treatment and to compare the efficacy of subgingival irrigating medicament being used in study

Randomized controlled clinical trial was performed on 45 patients that were divided into three groups, the ozone group (Group A), chlorhexidine group (Group B) and povidone iodine group (Group C). Patients underwent scaling and root planing (SRP) in a single visit followed by irrigation with ozone water, chlorhexidine and povidone iodine in. The clinical parameters of Gingival Index (GI), Plaque Index (PI), probing pocket depth (PPD), Clinical Attachment Level (CAL) and modified sulcular bleeding index were measured at baseline, at 1 month and at the end of 3 months.

All clinical parameters like plaque index, gingival index, probing pocket depth, clinical attachment level and modified sulcus bleeding index at baseline, 1 month and after 3 months. Ozone group was found to be superior than chlorhexidine followed by Povidone Iodine in terms of reduction of Plaque Index. However, intergroup comparison for other parameters did showed difference but it was not statistically significant.

: It can be concluded that use of ozone can serve as beneficial irrigating solution to treat chronic periodontitis for home care and professional practice. More studies with a larger sample size may be used to evaluate the potential of these irrigating agents.

Традиционные модели патогенеза сепсиса предполагают, что микроорганизмы или их продукты обязательно вредны для хозяина. В отличие от этого, эволюционная перспектива предполагает, что взаимодействия хозяин-микроб представляют собой симбиотическую модель и что заболевание является результатом нарушения взаимовыгодного гомеостатического состояния. Липополисахарид (ЛПС) грамотрицательных бактерий является прототипом триггера сепсиса и мишенью для разработки новых терапевтических средств. Биологические механизмы, лежащие в основе распознавания ЛПС и реакции на него, в большей степени характерны для гормона, чем для токсина. Все млекопитающие несут эндогенные запасы ЛПС и экспрессируют выделенные белки-переносчики, комплекс клеточных рецепторов и механизмы, которые специфически противодействуют реакции на ЛПС. Нарушение любого компонента этой сложной системы распознавания ставит под угрозу защитные силы организма против заражения экзогенными микроорганизмами. Таким образом, ЛПС является эндотоксином вне меньшей степени, чем экзогормоном, и его нейтрализация потенциально может привести либо к пользе, либо к вреду.

It is now 10 years since the first issue of the International Journal of Practice-Based Learning in Health and Social Care was published. Since then, there has been significant change; not just in practice learning itself but across health and social care, the ways people work and study, and in political and regulatory domains. As a way to celebrate the resilience of the journal and its contributions to the evidence base, we are delighted to have put together this special anniversary issue. The issue brings together 10 articles that highlight the range and excellence of the 157 publications from the past ten years. We also present an interview with two of the founding members of the journal, reflecting on the last ten years, including the developments and challenges that have characterised this time. To identify our ten articles, we started by looking at those articles which attracted most readers across the years. We then reviewed those popular articles, selecting a diverse mix of topics, professional backgrounds, geographies and research/evaluation approaches. Having selected articles for the special issue we asked the original authors to reflect on the impact of their work, highlighting its currency and sharing what happened next. These reflective commentaries capture the significance of the studies and their contributions to advancing practice-based learning.
Review of Translingual Dispositions: Globalized Approaches to the Teaching of Writing
Authors:   George Mason University,USA, Namubiru Esther
Published: January 2024

In this review of Frost, Kiernan, and Malley's collection Translingual Dispositions: Globalized Approaches to the Teaching of Writing, I propose that the collection fills a necessary gap of augmenting translingualism discourse globally and beyond the classroom. The contributors to Frost, Kiernan, and Malley's collection develop the theory of translingualism as an attitude, lived experience, an advocacy issue, and a classroom practice by showing a myriad of application sites for this concept. In so doing, the collection also demonstrates the messy operationalization and embodiment of translingualism in U.S. academic and non-U.S. academic settings.
The Biosorption of Mn(II) ions From Wastewater Using Water Hyacinth (Eichhornia crassipes) Roots: Adsorption-Desorption Studies and Kinetics

This study examined the sorption of Mn(II) ions from waste using dried and blended water hyacinth root (WHR). It focused on how the major process parameters influenced the sorption process. Mathematical models were proposed to explain both the equilibrium and kinetics of biosorption. A desorption study was conducted using different HNO3 and NaOH concentrations. An application study using actual industrial effluent was evaluated to analyze the fitness of the biosorbent at optimal batch conditions. The results demonstrated that the increasing initial Mn(II) ion concentration decreased Mn(II) ion removal, while an increase in the sorbent dosage increased its removal. For the rate of biosorption, the contact time was rapid between 15 and 45 min, and the maximum Mn(II) ion was removed within the initial 60 min. Equilibrium sorption was attained at pH 7, where maximum Mn(II) ion uptake was 94 %. The results also showed that Mn(II) ion biosorption at 30 °C and pH 7 for water hyacinth roots could be modeled by Langmuir and Freundlich isotherms and the pseudo-2nd order model. Furthermore, an effective desorption of Mn(II) was obtained with solutions of both NaOH and HNO3. The results also showed that the percentage biosorption and desorption of Mn(II) from the industrial wastewater were 64.68 and 27.95 %, respectively.

Lipases are widely used in a variety of industries, both to develop products and to improve process efficiency. The need for lipase increased along with the wider application of this enzyme. Therefore, studies related to the search for potential lipase-producing microbes that answer the needs of the industry are required to be carried out continuously. Enzymes produced by microbes are preferred because they can be produced quickly compared to other sources. Bacillus flexus InaCC-B486 was used to produce lipase in this study with olive oil as substrate. This research aimed to observe the production of lipase from B. flexus InaCC-B486 and characterize its activity. The result shows that the production of B. flexus InaCC-B486 lipase was optimal at day-4 which was 11.983 ± 0.101 U/mL. The activity of B. flexus InaCC-B486 lipase was optimal at an incubation time of 15 minutes (2.810 U/mL), pH of 8.0 (3.173 U/mL), and a temperature of 35 oC (3.173 U/mL). These findings can be used for further applications, both in research and industry, that use B. flexus InaCC-B486 as a resource for lipase production or any related applications.
Sport for Development and Peace in the United Nations: An Empirical Study on the Development of the Role of SDP in the UN in the Context of the Closure of the UNOSDP
Authors: Schreiner Laura , Kastrup Valerie , Mayer Jochen
Published: January 2024

In 2017, it was decided that the United Nations Office on Sport for Development and Peace (UNOSDP) is to be closed. This qualitative study aims to analyse the reasons for the closure as well as its effects on Sport for Development and Peace (SDP) in the United Nations. Against the background of the systems theory, we conducted interviews with participants from relevant organisations. It is shown that the way the UNOSDP worked underwent a change and that the new tasks as well as their fulfilment were viewed controversially. Additionally, broader changes in development policy set a new frame for SDP.
Pola Alokasi Buruh Tani dan Pengaruhnya Terhadap Produktivitas Usahatani Melon: Pendekatan Generalized Additive Model

Even though it is known that melon farming is labor-demanding, the allocation of hired labor is often overlooked as the subject of melon farming studies. To fill this void, this study aims to analyze the pattern of farm labor allocation and its effect on the productivity of melon farming. The data used in this research is primary data collected through a survey of 60 melon farmers selected using the convenience sampling method by considering the area of farming land. Data analysis included descriptive statistical analysis and non-parametric regression, namely the generalized additive model. The research results show that: (1) labor costs account for nearly 50% of variable production costs; (2) melon farms with a land area of more than 0.5 ha tend to employ more farm laborers than farms with less than 0.5 ha. Farm workers are even employed for farming activities that fall into the category of delicate works and have a significant impact on production, such as pest and disease control, pruning shoots, and fruit selection; and (3) the use of farm laborers in delicate works farming activities reduces melon productivity.
Alluvial Zones of Decolonizing Internationalization of Higher Education
Authors: Lin Gloria Y.
Published: January 2024

Universities play a critical role in the “alluvial mixing” of Indigenous and Western knowledges, but at the same time they are reluctant to dismantle structures that support their ongoing epistemic ignorance, epistemic biases, and epistemic dominance and are resistant to dismantle hierarchies that maintain the status quo (Marker, 2019). Decolonization and internationalization of higher education does not exist in separate realities, but exists in alluvial third spaces that are often turbulent, contested, and contradictory. This article encourages researchers, faculty, and staff to rethink assumptions about long-standing, deeply-rooted policies, practices, and structures of international student recruitment and enrolment that are characterized by dominating neocolonial values and priorities and to reimagine the practice of recruiting international students and competing in the global international student market by centering primacy of place where “land is not a soulless commodity” to be exploited and profited (Marker, 2019).
