Prisma: relationships, metamorphosis and queerness from Ovid and Vivinetto to Urciuolo-Bessegato's screenplay
Authors: Bertolio Johnny L.
Published: July 2024

La serie Prisma, produzione italiana che ha esordito nel 2022 su Amazon Prime Video, è ispirata alla raccolta poetica Dolore minimo (2018) di Giovanna Cristina Vivinetto. Scritta a quattro mani da Alice Urciuolo e Ludovico Bessegato, che ne è anche regista, la serie mostra uno sguardo libero da pregiudizi e stereotipi sull’adolescenza italiana di questi nostri anni Venti. La queerness non è tematizzata, piuttosto attraversa le relazioni tra protagonisti e protagoniste come un dato di realtà: orientamento sessuale, identità di genere, transizione arricchiscono il racconto riallacciandosi, oltre i versi di Vivinetto, a una fiorente e spesso dimenticata tradizione letteraria, che risale alle Metamorfosi di Ovidio e al mito greco. L’articolo esamina lo spessore poetico della sceneggiatura e della colonna sonora, la prospettiva queer di alcuni episodi e gli effetti complessivi, nel solco della produzione di Bessegato dedicata all’adolescenza e iniziata con Skam Italia (dal 2018).
Del neorrealismo al neorruralismo. La migración rural a través del análisis comparado de La piel quemada (Josep Maria Forn, 1967) y Suro (Mikel Gurrea, 2022)
Authors: Martínez Puche Salvador , Martínez-Puche Antonio
Published: July 2024

La ficción cinematográfica funciona como un eficaz dispositivo epistemológico para interpretar y comprender un tiempo y un espacio determinado que adquieren una dimensión más simbólica y narrativa que estrictamente histórica y geográfica. El análisis comparado de las películas La piel quemada (Josep Maria Forn, 1967) y Suro (Mikel Gurrea, 2022) ofrece una perspectiva diacrónica y sincrónica sobre la representación del flujo migratorio tardofranquista de «charnegos» y más recientemente de urbanitas y magrebíes. Ambos largometrajes, catalogados como cine rural por su contexto espacial y temático, se localizan en la provincia de Girona y muestran, por una parte, el despoblamiento de aldeas granadinas en busca de oportunidades laborales en el litoral turístico de la Costa Brava durante el desarrollismo; y, por otra, la repoblación llevada a cabo por neorrurales barceloneses y jornaleros extranjeros en la comarca interior del Alt Empordà. La metodología cualitativa cronotópica atiende a la dimensión argumental y axiológica para organizar los resultados en cuatro factores decisivos que influyen en las causas y motivaciones, así como en las consecuencias identitarias, individuales o colectivas, y los conflictos xenófobos originados por estos desplazamientos.
El paisaje realista en el anime: de la estética en la obra de Makoto al mensaje de Estudio Ghibli
Authors: Cabezas Morales Marina Eva , García Ramos María Dolores
Published: July 2024

La importancia del paisaje natural en el arte es innegable, especialmente para la pintura y el cine. La animación japonesa, como unión de ambos géneros artísticos, es uno de los mejores ejemplos a la hora de ver cómo el paisaje realista se desarrolla como una de las características fundamentales para la confección de sus obras. Por medio de las producciones de Makoto Shinkai, Isao Takahata y Hayao Miyazaki comprobaremos cómo la representación de los escenarios se convierte en una de las peculiaridades del Anime, convirtiéndose en un elemento de significación dentro de la obra.
Música y tierra. Agricultores vs ganaderos en El Forastero (William Wyler, 1941)
Authors: Pérez García Lucía
Published: July 2024

El conflicto entre agricultores y ganaderos fue uno de los principales problemas con los que tuvieron que lidiar las autoridades norteamericanas durante los años de expansión de la frontera. La tierra como forma de vida, entendida desde un doble punto de vista: como terreno de cultivo y como zona de paso y pasto, llevó a los primeros pobladores del Oeste americano a librar verdaderas batallas legales. En El forastero, William Wyler presentó este conflicto como parte y fondo de una historia de amor y justicia, donde la tierra, como elemento de unión y futuro, termina saliendo vencedora. Entre todos los apartados que dan forma a este concepto, la música de Dimitri Tiomkin adquiere un papel fundamental. Su análisis dentro del contexto de la historia y del género cinematográfico ayuda a construir significados y a transmitir de forma más efectiva la lucha por un medio de vida, y por el futuro.
Entre la desidia y la avidez: Guinea en el documental español
Authors: Torreiro Casimiro
Published: July 2024

Capítulo clave en el desarrollo del cine colonial español, los 32 cortometrajes rodados entre 1944 y 1946 en la entonces llamada Guinea Española por un equipo de Hermic Films, capitaneado por el productor, operador, fotógrafo y director Manuel Hernández Sanjuán, constituyen el corpus más completo jamás rodado en el África tropical por cineastas españoles. Relevamiento completo de la vida en la colonia desde la óptica de los colonialistas, en esos cortometrajes se puede rastrear el interés de los cineastas por mostrar los procesos extractivos de la madera en las selvas ecuatoriales, así como un buen número de otros temas, desde el cultivo del café y el cacao, hasta la educación y el encumbramiento de las ceremonias y servidores del Poder: gobernadores, sacerdotes, capitanes de empresa. Pero también el racismo implícito de los comentarios, el subrayado de la superioridad de los blancos sobre los «indígenas» atrasados y hasta algunos esbozos de etnografía que hacen del conjunto de films un momento perfecto para el análisis de la construcción de imaginarios vinculados a las posesiones de ultramar.
Research on the algorithm for optimal selection of detection modes for rail crack detection
Authors: Liu Jianjun , Fan Lanlan , Luo Huan , Yang Senquan
Published: July 2024

In the application of ultrasonic guided wave testing for rail crack detection, it is necessary to select a guided wave mode that is more sensitive to cracks as the detection mode. However, ultrasonic guided waves have multi-mode and dispersive characteristics. In order to extract mode information from complex signals, this paper proposes an optimal detection mode selection method based on the sensitivity of guided wave modes to cracks. This method is different from the traditional method of determining mode types by calculating the mode velocity through the arrival time of wave packets in the time domain signal. Based on the dispersion characteristics and mode features of guided wave modes, this paper establishes a crack sensitivity evaluation index. In a wide frequency band and among numerous modes, the guided wave modes suitable for detecting cracks in different regions of the full cross-section of rails are accurately selected. Experimental results show that the guided wave modes selected by the mode selection method proposed in this paper, based on the crack area energy and crack reflection intensity evaluation indexes, can accurately identify rail cracks, laying a foundation for the research on rail crack detection and localization methods.
Self-tuning control of steam sterilizer temperature based on fuzzy PID and IPSO algorithm
Authors: Zhai Wenzheng , Dong Liangwei , Hu Yueli
Published: July 2024

A time-varying process with nonlinearity and time lag is the temperature control of pulsing vacuum steam sterilization. In order to achieve efficient and accurate control requirements, conventional PID temperature control algorithms sometimes display slow response speed, severe overshooting, unstable performance, and other challenges that ultimately affect the sterilizing effect. In order to find the ideal steam sterilization temperature control settings iteratively, this research used the PSO algorithm. Simulating and analyzing the system model is done simultaneously using fuzzy control of the PID parameter adaptive modification. According to the results, there is no overshooting and the response speed approach is faster. This paper presents an approach to fuzzy PID control based on the PSO optimization algorithm. As a result of fuzzy adaptive PID's high control accuracy and quick response time, the PID parameters are also continuously optimized utilizing the PSO approach for steam sterilization temperature control. For the purpose of doing simulation analysis, create and modify a system model. As evidenced by the results, this strategy has a reduced overshoot, a faster response time, and better stability. It may also successfully boost the control effect. Eventually, this method was applied to a self-tuning PID control experiment for sterilizer temperature control, and a relatively optimal control effect was obtained.

Published: July 2024

To address the problems of low detection accuracy of rolling bearings under different loads and the difficulty of effectively identifying the lack of labelled data, a rolling bearing fault diagnosis method combining GADF-DFT image coding and Multi-kernel domain coordinated adaptation network is proposed. Firstly, the vibration signal is converted into a two-dimensional image using GADF coding technology, and then the GADF image is converted into the frequency domain using discrete Fourier transform to extract deeper feature information. Combined with the multi-source domain adaptive method, the public feature extraction module is used to initially achieve feature mining of the image; the MK-MMD algorithm of the domain-specific adaptive module reduces the difference in feature distribution between the source and target domains; and the final classification difference minimization module reduces the problems caused by the classification errors that may be generated by the different domain classifiers due to the fact that the data samples are located near the category boundaries. The test uses the Case Western Reserve University dataset and divides the dataset with different operating conditions as the source and target domains, and the test results show that the proposed model demonstrates its effectiveness in responding to the complex operating condition changes in rolling bearing fault detection in multiple operating condition migration tasks, good adaptability and robustness, and is able to achieve accurate fault diagnosis under different operating conditions.

Published: July 2024

To further investigate the synergistic effects of Fe (Ⅲ) and graphene derivatives with varying degrees of oxidation for photocatalysis, commercial titanium dioxide nanoparticles and graphene oxide were employed as precursors to synthesize the catalyst in this study. Graphene oxygenated derivatives and Fe (Ⅲ)-modified titanium dioxide photocatalysts with different oxidation degrees were prepared using a simple one-step solvothermal method. The results demonstrated that the photocatalytic performance in degrading rhodamine B and sulfamethoxazole was enhanced with an increase in the oxidation degrees of graphene materials. Through the combined action of delocalized conjugated π electrons as electron transfer mediators, Fe (Ⅲ) as an electron trap, and photosensitization reactions, titanium dioxide exhibited exceptional photocatalytic properties with the assistance of graphene derivatives and Fe (Ⅲ) co-catalysts in the degradation of organic compounds.
Formation of meandering streams in a young floodplain within the Yarlung Tsangpo Grand Canyon area in the Tibetan Plateau
Authors: Cheng Yunshuo , Li Zhiwei , Yu Guo-An , Yao Weiwei , Chen Bang
Published: July 2024

A recent discovery of two unique meandering streams near the Yarlung Tsangpo Grand Canyon facilitates the present study. Given the contrasting channel patterns compared with the surrounding bedrock and braided reaches, as well as their recent formation due to dam-induced topographic changes within the valley, this study offers critical insights into the formation and evolution processes of meandering channels. It is found that, first, the prolonged sedimentation process due to the backwater of the mainstream of the floodplain proves a material base for the formation of the meandering river. Proper bank strength provided by the floodplain (stratified layer of root-soil composite and silty clay) contrasts the stream from a braided pattern into a single-threaded pattern, then the alternate bar in the upstream preludes the meandering channel formation. The annual migration rate of the stream is consistent with other large-scale natural meandering rivers. Congruences and disparities with the analytical meandering migration model of the present stream (that the meandering path follows the Kinoshita curve with noticeable flatness but no skewness) highlight the complex interplay of local factors in shaping meandering processes, offering valuable insights into both the unique characteristics of the Cuoka streams and the broader principles governing meander formation.

Published: July 2024

Sustainable Development Goal (SDG) 6 aims to achieve ‘access to adequate and equitable sanitation and hygiene for all and end open defaecation’ by 2030. We present an in-depth investigation of sanitation and hygiene practices of 939 Malawian households in two districts, previously declared open defaecation-free (ODF). We evaluated whether ODF status was maintained by evaluating access to sanitation and hygiene. We found that 17% returned to open defaecation, and faeces were observed around 10% of the households. We suggest that ODF status is not enough; work is required to maintain progress and consideration of construction quality is critical. Another barrier to SDG 6.2 was that only 7.9% of households had handwashing facilities with soap and water, with soap as a major limitation. However, most households (82%) had soap available for washing suggesting that soap is not being prioritised in handwashing.

Published: July 2024

In this study, an extensive and methodical investigation was carried out to comprehend the different geochemical processes, factors governing the hydrochemical composition and water suitability for drinking, irrigation and industrial usage in the Periyar River Basin (PRB). A total of 300 samples were collected from the mainstream, tributaries and dams of the river during PREM (Pre-Monsoon), POM (Post Monsoon), NEM (North-East Monsoon) and SWM (South-West Monsoon). The results suggested that the cationic composition is chiefly characterized by the predominant presence of Ca2+ and Mg2+ while Cl− dominates the anionic composition followed by HCO3-. The results identified transitional waters. Gibb's diagram revealed that the ionic composition dominance in the study area is influenced by the chemistry of the host rock rather than precipitation and evaporation. A comparatively greater pCO2 (>10−3.5 atm) shows an atmospheric disequilibrium in natural waterbodies due to both anthropogenic activities and input of baseflow to stream discharge. The Water Quality Index showed excellent (0–25) to unsuitable (>300) category during NEM, POM and PREM with significant spatial variation along the river. Integrated irrigational suitability indices illustrated the suitability of the samples for agricultural use, except for a few samples in the lowland region.

Tropical cyclones (TCs) contribute significantly to rainfall along Vietnam's coast, yet their complex precipitation structures remain poorly resolved, hindering forecast skill. This study analyzes TC rainfall distributions over the Vietnam East Sea from 2000 to 2020. The Global Satellite Mapping of Precipitation (GSMaP) product provides precipitation estimates with 0.1° resolution at hourly intervals, enabling detailed structural characterization. Rainfall features are analyzed across TC intensities, motion vectors, landfall locations, and interactions with cold surge (CS) air masses. Results show that total coverage differences are less significant than the intensity variations in narrow inner core rainbands. Asymmetric rainfall distributions concentrate in the front-right quadrant but shift after landfall. Northern Vietnam observes higher TC frequencies, but southern regions experience heavier extreme rains. Additionally, CS intrusions substantially intensify eyewall convection and redirect TC precipitation. These structural sensitivities visible in GSMaP observations elucidate the dynamics modulating TC rainfall. Characterizing multi-scale interactions and precipitation processes aids in forecasting and impact assessment for these high-risk storms with complex regional behavior.

Mangrove-inhabited coastal areas are seriously threatened by climate change that disturbs the sustenance of dependent native communities. This study assesses the status of climate variables to identify and evaluate climate change–induced vulnerabilities to fishers and recommend mitigation measures at a regional scale in the Pichavaram Mangroves, a Ramsar wetland of international importance in India. The time series climate data (1951–2021) revealed an insignificant increase in annual rainfall (p> 0.05) and a significant increasing trend (p< 0.05) for mean annual temperature. The results of the stakeholder-based approach (n = 240) indicate that mangrove dwellers experience ecological and health-based vulnerabilities and estuarine fishers face community and nutritional issues. Fishers of this wetland are prone to resources (60.5) and user-based vulnerabilities (59.03). The overall vulnerability index places fishers of the mangrove/estuary (T.S.Pettai: 54.13; Killai: 53.04; Pichavaram: 52.91) more vulnerable than the marine region (Mudasalodai: 49.84). This study suggests social networking, skill development, awareness of welfare schemes, ecotourism, sustainable fishing, climate research for developing mitigation strategies, and fisheries enhancement to combat climate change impacts. Furthermore, building resilience among the stakeholders and resource management through a citizen science approach is crucial to lessen climate change vulnerability in coastal wetlands in India, and elsewhere.
Rising groundwater levels in Dare County, North Carolina: implications for onsite wastewater management for coastal communities
Authors: O'Driscoll Michael , Humphrey Charles , Iverson Guy , Bowden Jared , Harrison Jane
Published: July 2024

Onsite wastewater treatment systems (OWTS) are a common wastewater treatment approach in coastal communities. Vertical separation distance (VSD) requirements between the drainfield and groundwater aim to ensure aerated soils for wastewater treatment. When the VSD declines, OWTS can fail. This study evaluated groundwater response to sea level rise (SLR) and the implications for OWTS. A groundwater monitoring network (13 wells) was used to evaluate groundwater depth in Dare County, North Carolina. Groundwater levels were measured with water level meters and pressure transducers. Trends in groundwater depth and SLR were analyzed to evaluate the influence of SLR on groundwater depth. From 1984–2022, mean groundwater levels have risen (∼7.6 mm/year) in response to SLR. Currently, sites at <2.7 m land elevation are most likely to have groundwater depths <1 m and inadequate VSD. Based on current precipitation and NOAA intermediate SLR projections, groundwater depth projections suggest that OWTS at lower elevations are more likely to experience groundwater inundation by 2040–2060. SLR has resulted in reduced VSD causing diminished wastewater treatment capacity in low-lying areas. OWTS VSD requirements are typically static due to regulatory constraints. Future management approaches should consider adapting to rising coastal groundwater levels because of increasing wastewater contamination risks.
‘You scratch my back, I'll scratch yours’: An examination of actor engagement in water public private partnerships
Authors: Elder Alison D. , Gerlak Andrea K.
Published: July 2024

Public–private partnerships, or PPPs, first gained prominence in the water sector with the promise of providing more efficient and lower-cost water services and infrastructure. Despite criticism, water PPPs continue to grow globally and receive support from a diverse set of actors around the globe. This empirical research uses a combination of inductive and deductive approaches to study the engagement of key actors in water PPPs, including the private sector, non-governmental organizations, and intergovernmental organizations. We map out the differing relationships across key actors engaged in water PPPs to examine the interdependencies between actors. We uncover how actors help to serve or promote water PPPs and how, in turn, water PPPs help with the achievement of different actor goals. Our findings reveal how through PPPs, private sector actors utilize the sustainable development goals as a form of moral authority to exhibit corporate social responsibility. We also find that the unique capabilities of pro-PPP NGOs enable them to serve as connectors between actors in facilitating water PPPs. As climate change increasingly strains water resources globally, understanding the goals, motivations, and capabilities of the diverse actors engaged in the water sector is crucial for addressing water challenges going forward.

Authors: Prakash Anjal , Kumar Noor , Chhatre Ashwini , Thakkar Shriya , Dar Aaditya
Published: July 2024

The rate of groundwater extraction has seen an exponential rise in India over the past few decades. Several districts in the country face groundwater depletion and contamination issues, threatening agricultural and domestic usage. The overexploitation of the resource can be attributed to the sowing of water-intensive crops, distortionary subsidies, the absence of incentives, asymmetrical information, and regulatory bottlenecks. This paper presents a comparative analysis of the experiences of various states of India in regulating groundwater extraction. It discusses both the legal and institutional components of the current framework and explores groundwater conservation policies from both the demand and supply sides. The paper highlights the issues of zoning and registration of wells, the promotion of water-saving practices, the implementation of recharge projects for aquifers and wells, and the improvement of groundwater governance as potential solutions to alleviate the ongoing crisis. Furthermore, the paper emphasises the importance of sustainable management, community engagement, and regulatory frameworks to tackle issues like groundwater depletion. Lastly, it suggests actionable steps for policymakers to promote sustainable practices and ensure a secure future for India's groundwater resources.
An experimental investigation for the determination of the optimum ratio of nano clay for reducing local scour around a cylindrical bridge pier
Authors: Dheyab Abubaker Sami , Günal Mustafa
Published: July 2024

Local scour is one of the main causes of the bridge collapse. It occurs when the flow erodes the sediments surrounding the bridge's piers. This experimental study aims to find an innovative approach for armoring the bed using nano clay to mitigate the erodibility of non-uniform sand beds. Additionally, the study investigates the nano clay-sand bed under various hydraulic conditions, with different pier diameters to determine the optimal nano clay ratio for minimizing local scour around a cylindrical bridge pier. This study indicates that the nano clay could be used effectively to reduce the local scour depth, with an optimum ratio of 0.25% when the flow shallowness is less than 1.4 and an optimum ratio of 0.5% for the flow shallowness between 1.4 and 2. Notably, a significant reduction of up to 68% in local scour depth is observed out of all experiments. Furthermore, the study demonstrates the influence of nano clay on other factors related to local scour depth. It presents a predictive equation that can be used to estimate the depth of local scour in a bed composed of nano clay and non-uniform sand. This equation is derived from the obtained data from this experimental investigation.

Authors: Babich S. G. , Darda E. S.
Published: July 2024

Purpose of the study. One of the most important functions of the Russian banking sector is the accumulation of temporarily free funds of the population for further active operations, including lending to legal entities and individuals. The volume of deposits of individuals is influenced by various factors, the main ones being indexes of the standard of living of the population, which vary significantly in the regions of the country. In the context of significant differences in the spatial development of regions, it is advisable to carry out a statistical analysis of the influence of the main indexes of the standard of living of the population on the volume of funds attracted by credit institutions from the population in the regions of the Russian Federation. The purpose of this study is a statistical analysis of the dynamics and structure of household deposits, as well as an assessment of the impact of the main indexes of the population’s standard of living on the volume of household funds attracted by credit institutions.Research methods and sources of information. The following statistical tools were used: structural and dynamic analysis, cluster analysis, correlation and regression analysis, as well as tabular and graphical methods for presenting research results. The information base is the official statistical data of the Federal State Statistics Service (Rosstat) and the Central Bank of RussiaResearch results. The analysis of the dynamics of the volume of deposits of individuals showed an increase in the volume of private deposits in rubles with a significant reduction in deposits in foreign currency in all federal districts of the country. As a result of studying the regional structure of deposits of individuals in credit institutions, three federal districts can be identified, the share of which is 73,5% in the total volume of private deposits in the country. The use of the cluster analysis method made it possible to identify three groups of regions. The first cluster included three subjects that are characterized by the highest values of the volume of deposits per capita. The second cluster consisted of 66 regions of the country in which the level of development of savings remains low. In 13 subjects included in the third cluster, there is an average level of depositing funds in credit institutions of the country. The use of the method of correlation and regression analysis made it possible to identify the most significant impact on the volume of private deposits per capita of the average per capita monetary income of the population, i.e. a high level of cash income will contribute to an increase in the volume of citizen deposits attracted by credit institutions, as well as a moderate direct impact of the level of employment of the population. In addition, in certain groups of regions, the degree of influence of factor characteristics on the volume of private deposits per capita varies.

Purpose of the study. The article presents the results of a statistical analysis of the nutritional characteristics of the population of the Republic of Mordovia to assess their eating behavior in accordance with the principles of healthy nutrition.The results of the study showed inconsistency with rational standards of consumption of basic food products by the population of the republic. The most pronounced deficit in the diet of the population of the republic is observed in the consumption of vegetables and melons, milk and dairy products and vegetable oil. Significant excess of the recommended norm is typical for the consumption of sugar, bread products, potatoes, meat, meat products and eggs. A reduction in the food energy value of the daily diet was revealed to 2600 kcal versus 3126 kcal according to rational consumption standards.Materials and methods. As a methodological basis for the study, an aggregation method was used, which makes it possible to calculate indexes of the benefits of consumption of basic food products by the population of the Volga Federal District regions: advance, parity and lag from recommended rational consumption standards. The calculation of the integral assessment of the nutrition quality of the population was carried out without taking into account the weighting coefficients of the main food groups.The information base of the study is data from the Federal State Statistics Service. The results of the study confirm the existence of differentiation in food consumption and its quality in the regions of the Volga Federal District. Not a single region has been identified with parity in terms of recommended rational nutritional standards. In two regions (Udmurt and Chuvash Republics), there is an approximation to rational consumption standards. In four regions of the Volga Federal District (Perm Krai, Penza, Saratov and Ulyanovsk regions) consumption lags behind the recommended rational norms. In other regions, there is an excess of rational consumption standards for most food products. This group of regions includes the republics of Bashkortostan, Mari El, Mordovia, Tatarstan, Kirov, Nizhny Novgorod, Orenburg and Samara regions. For the Republic of Mordovia, the value of the integral assessment was 1,052.Conclusions. The need to continue activities to develop healthy lifestyle priorities among the population through a culture of nutrition, as laid down in the Federal Project “Strengthening Public Health” was noted.
Bilateral Relationships Between Catastrophe and Sovereign Bonds on the Example of a Number of Countries of the Belt and Road Initiative
Authors: Savrasov K. K. , Rudy K. V. , Gorbachev N. N.
Published: July 2024

The article proposes a method for assessing the bilateral relationships between catastrophe and sovereign bonds to analyze financial risks within the framework of China’s global infrastructure initiative “Belt and Road”. Countries included in the China - EU land transport corridor have a high risk of natural disasters, which could negatively affect the infrastructure being created and local communities. Investments in infrastructure projects by China are often made subject to sovereign guarantees from partner countries. In case of natural disasters, the traditional use of state reserve funds is not always effective, since the insurance markets of the countries of the China - EU land transport corridor are dominated by protectionism, the indicator of which is the low level of import of insurance services. As a more effective tool for covering losses in the event of catastrophic threats to the infrastructure of the China - EU transport corridor, one can consider insurance derivatives (Insurance Linked Securities - ILS) and sovereign parametric catastrophe bonds, in particular. The article analyzes the relationship between catastrophe and sovereign bonds of a number of countries (China, Kazakhstan, Russia, Turkey). Based on the results of testing the hypothesis (H1), the dependence of the interest rate on sovereign bonds of Kazakhstan, China, Russia and Turkey on the interest rates on catastrophic bonds of the Swiss Re Cat Bonds Index was established. A complete inverse relationship between catastrophe bond rates and sovereign bond rates, in accordance with hypothesis (H2), was not revealed.

One of the efforts to mitigate climate change is the preservation of mangrove ecosystems because of their function as carbon storage and absorbers. The coast of Karawang Regency is a potential area for mangrove ecosystems, but information on existing carbon stocks and sequestration is not yet known, let alone the contribution of mangrove rejuvenation, including from rehabilitation seedlings. The study results show that the total carbon stock on the coast of Karawang Regency ranges from 13.75 – 56.89 MgC ha–1  or 5,799.88 – 24,003.58 MgC. This value is obtained from the contribution of three main species, namely A. marina of 4.38 – 15.38 MgC ha–1, R. apiculata of 5.80 – 24.63 MgC ha–1, and R. mucronata of 3.57 – 16.88 MgC ha–1. The carbon sequestration value (CO2-equivalent) on the coast of Karawang Regency ranges from 50.40 – 208.58 MgCO2-eq ha–1 or an overall of 21,266.23 – 88,013.14 MgCO2-eq. This value was obtained from the contribution of three main species, namely A. marina of 16.07 – 56.41 MgCO2-eq ha–1, R. apiculata of 21.25 – 90.29 MgCO2-eq ha–1, and R. mucronata of 13.08 – 61.88 MgCO2-eq ha–1. The total contribution value of stock and carbon sequestration from mangrove rejuvenation in the simulation up to 10 years of diameter growth reached 24.58 MgC year–1  and 90.14 MgCO2-eq year–1. These values are an accumulation of three categories of youth, namely the existing sapling category (7.86 MgC year–1 and 28.82 MgCO2-eq year–1), the existing seedling category (4.72 MgC year–1 and 17.32 MgCO2-eq year–1), and the seedling category (3.64 MgC year–1  and 13.33 MgCO2-eq year–1).

The impact of technological advancements on the labor market and innovation processes is a critically important research area. The aim of this study is to examine the emergence and frequency of technological innovations in scientific publications, with a particular focus on the Journal of Labour Economics from 2000 to 2020. The research employs content analysis methods, searching for eight different terms and expressions related to technological development (e.g., technology, artificial intelligence, machine learning) across 1405 articles. The study also analyzes the number of occurrences and annual publication trends of these terms. A total of 9469 instances were identified, indicating that in 64,7% of the cases, at least one technological term appeared. An analysis of annual trends reveals an increase in the usage of certain keywords (technology, artificial intelligence, and machine learning). In a smaller subset of articles, only 1%, technological terms were mentioned at least 50 times. The results suggest that although the topic of technological development plays a significant role in labor market research, the frequency of its appearance and the depth of analysis vary considerably. The increase in the appearance of technological terms is predominantly observed in the fields of artificial intelligence and machine learning. These findings are specific to a single journal, indicating the need for further research involving other labor market journals to ensure representativeness.

So far there has been no study that has carried out mapping of study programs, facilities and infrastructure including laboratories and health services offered to the community. Judging from the literature review at all Sports Faculties in Indonesia, the aim of this research is to map the potential of sports faculties throughout Indonesia through study programs, laboratories and service facilities so that the potential of sports faculties is known. This research method involves collecting data from libraries and exploring research objects using various sources of library information, such as books, encyclopaedias, scientific journals, newspapers, magazines, and digital documents. The sample for this literature study consisted of 15 campuses that have sports faculties. Universitas Negeri Yogyakarta has the greatest number of sports study programmes among all campuses. UNM offers a sports faculty provided with appropriate and diverse related laboratories. There are five campuses, namely UPI, UNJA, UNIMA, UNDIKSHA, and UNCEN, which provide limited information about their laboratories. Currently, only UNESA, UM, and UNY have virtually identical quantitative measures. Surabaya and Yogyakarta State Universities own the majority of service facilities, while other sports campuses require new facilities to produce financial resources for universities and provide services to the public and academic community. Collaboration among sports institutions in Indonesia is necessary to cultivate proficient sports graduates across different locations. In addition to fostering healthy rivalry among sports faculties to promote their development, each campus should also seek suitable benchmarks based on their unique qualities, ensuring that each sports faculty have distinct advantages. There is a hope to establish sports universities in Indonesia as part of long-term planning.
Just-in-Time Adaptive Interventions for Behavior Change in Physiological Health Outcomes and the Use Case for Knee Osteoarthritis: Systematic Review
Authors: Fiedler Janis , Bergmann Matteo Reiner , Sell Stefan , Woll Alexander , Stetter Bernd J
Published: July 2024

Background

The prevalence of knee osteoarthritis (KOA) in the adult population is high and patients profit from individualized therapy approaches. Just-in-time adaptive interventions (JITAIs) are upcoming digital interventions for behavior change.

Objective

This systematic review summarizes the features and effectiveness of existing JITAIs regarding important physiological health outcomes and derives the most promising features for the use case of KOA.

Methods

The electronic databases PubMed, Web of Science, Scopus, and EBSCO were searched using keywords related to JITAIs, physical activity (PA), sedentary behavior (SB), physical function, quality of life, pain, and stiffness. JITAIs for adults that focused on the effectiveness of at least 1 of the selected outcomes were included and synthesized qualitatively. Study quality was assessed with the Quality Assessment Tool Effective Public Health Practice Project.

Results

A total of 45 studies with mainly weak overall quality were included in this review. The studies were mostly focused on PA and SB and no study examined stiffness. The design of JITAIs varied, with a frequency of decision points from a minute to a day, device-based measured and self-reported tailoring variables, intervention options including audible or vibration prompts and tailored feedback, and decision rules from simple if-then conditions based on 1 variable to more complex algorithms including contextual variables.

Conclusions

The use of frequent decision points, device-based measured tailoring variables accompanied by user input, intervention options tailored to user preferences, and simple decision rules showed the most promising results in previous studies. This can be transferred to a JITAI for the use case of KOA by using target variables that include breaks in SB and an optimum of PA considering individual knee load for the health benefits of patients.
Effect of Elastic Resistance on Exercise Intensity and User Satisfaction While Playing the Active Video Game BoxVR in Immersive Virtual Reality: Empirical Study

Published: July 2024

Background

One of the main contemporary forms of physical activity (PA) involves exercises and games in an immersive virtual reality (VR) environment, which allows the user to practice various forms of PA in a small space. Unfortunately, most of the currently available VR games and workout applications are mostly based on upper body movements, especially the arms, which do not guarantee sufficiently high exercise intensity and health benefits. Therefore, it is worth seeking solutions to help increase the exercise load during PA in VR.

Objective

The main aim of this study was to evaluate the effect of elastic arm resistance in the form of latex resistance bands of different elasticity levels on the intensity of students’ PA while playing the BoxVR game. We further assessed the satisfaction of this form of exercise and its associations with PA intensity.

Methods

A total of 21 healthy and physically fit men (mean age 22.5, SD 2.0 years) were included in the study. The tests consisted of 3 10-minute games. One game was run with no load and the other two were run with 1.5-meter latex resistance bands (low and high resistance). The order of the tests was randomized and the participants rested for 20 minutes after each exercise. Exercise intensity was estimated using objective (heart rate monitoring) and subjective (Borg scale) methods. The Physical Activity Enjoyment Scale was used to assess satisfaction with the PA. The effect of elastic resistance on exercise intensity and user enjoyment was estimated using ANOVA for repeated measures.

Results

The ANOVA results indicated that incorporation of elastic resistance caused a significant change (F2,40=20.235, P<.001; η²p=0.503) in the intensity of PA in VR, which was low while playing without resistance and then increased to a moderate level with additional resistance. The use of elastic bands also changed participants’ perceptions of the enjoyment of exercise in VR (F2,40=9.259, P<.001; η²p=0.316). The students rated their satisfaction with PA in VR on a 7-point scale highly and similarly when exercising without an upper limb load (mean 6.19, SD 0.61) and with slight elastic resistance (mean 6.17, SD 0.66), whereas their satisfaction declined significantly (mean 5.66, SD 0.94) when incorporating a higher load.

Conclusions

The intensity of PA among students playing the BoxVR game is at a relatively low level. With the added resistance of elastic bands attached to the upper limbs, the intensity of the exercise increased to a moderate level, as recommended for obtaining health benefits. Participants rated the enjoyment of PA in VR highly. The use of slight elastic resistance did not negatively affect satisfaction with the BoxVR game, although user satisfaction declined with a higher load. Further research should be undertaken to increase the effectiveness of exercise in VR so that regular users can enjoy the health benefits.
