Quantum Mechanics and Inclusive Materialism
Authors: Pérez-Jara Javier
Published: September 2024

Since its inception, the intricate mathematical formalism of quantum mechanics has empowered physicists to describe and predict specific physical events known as quantum processes. However, this success in probabilistic predictions has been accompanied by a profound challenge in the ontological interpretation of the theory. This interpretative complexity stems from two key aspects. Firstly, quantum mechanics is a fundamental theory that, so far, is not derivable from any more basic scientific theory. Secondly, it delves into a realm of invisible phenomena that often contradicts our intuitive and commonsensical notions of matter and causality. Despite its notorious difficulties of interpretation, the most widely accepted set of views of quantum phenomena has been known as the Copenhagen interpretation since the beginning of quantum mechanics. According to these views, the correct ontological interpretation of quantum mechanics is incompatible with ontological realism in general and with philosophical materialism in particular. Anti-realist and anti-materialist interpretations of quantum matter have survived until today. This paper discusses these perspectives, arguing that materialistic interpretations of quantum mechanics are compatible with its mathematical formalism, while anti-realist and anti-materialist views are based on wrong philosophical assumptions. However, although physicalism provides a better explanation for quantum phenomena than idealism, its downward reductionism prevents it from accounting for more complex forms of matter, such as biological or sociocultural systems. Thus, the paper argues that neither physicalism nor idealism can explain the universe. I propose then a non-reductionistic form of materialism called inclusive materialism. The conclusion is that the acknowledgment of the qualitative irreducibility of ontological emergent levels above the purely physical one does not deny philosophical materialism but enriches it.

Published: September 2024

We demonstrate a low latency delay of a radio frequency (RF)–linear frequency-modulated (LFM) pulse by modulating it onto optical carriers from a Kerr comb and sending the signal through a concatenation of off-the-shelf linearly chirped fiber Bragg gratings (LC-FBGs) and chirped-and-sampled FBG (CS-FBG). We characterize the frequency response and latency of the LC-FBG and CS-FBG. Then, experimentally, the LFM pulse performance is characterized by measuring the peak sidelobe level (PSL) at the output of the tunable delay system. The experiment, performed with an LFM pulse of 1 GHz bandwidth at a 10 GHz center frequency, shows a PSL better than 34.4 dB, attesting to the high quality of the buffer RF transfer function. Thus, the proposed optical memory buffer architecture, utilizing compact devices based on a Kerr comb and FBGs, offers several benefits for delaying LFM pulses, including (i) a larger tunable delay range, (ii) low latency, (iii) wide bandwidth, and (iv) high PSL.

Published: September 2024

Augmented reality overlays computer-generated virtual information onto real-world scenes, enhancing user interaction and perception. However, traditional augmented reality optical systems are usually large, bulky, and have limited optical performance. In this paper, we propose a novel compact monochrome reflective dielectric metalens visor with see-through properties, engineered using a periodic structure of spin-dependent supercells. The supercell, which is composed of staggered twin nanofins, provides spin-dependent destructive or constructive interference with different circularly polarized incidences. The design combines the principles of interference with the Pancharatnam–Berry phase to enhance reflection at a working wavelength of 650 nm while maintaining good transmission. Right circularly polarized light incident from the substrate side causes destructive interference, enabling the supercell to work in reflection mode, while left circularly polarized light causes constructive interference, enabling the supercell to work in transmission mode. Furthermore, the supercell-constructed metalens can achieve near-diffraction-limited reflective focusing and a broad diagonal field of view of approximately 96°. In addition, compared to transmissive metalens visors, the reflective design eliminates the need for a beam splitter, significantly reducing the size and weight of the system. Our work could facilitate the development of compact and lightweight imaging systems and provide valuable insights for augmented reality near-eye display applications.

Authors: Huang Yijie , Zhong Renbin , Zhang Zhenhui , Huang Lin
Published: September 2024

This study proposes a differential wavelength measurement method based on the electromagnetic-induced photoacoustic effect. The differential method involves irradiating the sample with multiple wavelengths and utilizing differences in absorption characteristics across different materials to calculate and measure the excitation light wavelengths. Compared to traditional detection methods, this approach combines the unique properties of electromagnetic-induced photoacoustic effect, offering high sensitivity and a wider detection range from microwave to light. Furthermore, the system is structurally simple and stable, suitable for non-destructive testing of various materials, including wavelength-sensitive biological tissues. The experimental results demonstrate that combined with Polymers Benzodithiophene Triazole–Quinoxaline (PBTQ) and Single-Walled Carbon Nanotubes (SWCNTs) as absorbing media, this technique provides a rapid and cost-effective means of wavelength measurement, achieving an uncertainty of approximately 2.33 nm within the range of 680–800 nm, and it can be used for wavelength/frequency measurement of various electromagnetic waves.

Published: September 2024

With the development of unconventional natural gas resources, plunger gas lift technology has gained widespread application. Accurately predicting gas production from unconventional gas reservoirs is a crucial step in evaluating the effectiveness of plunger gas lift technology and optimizing its design. However, most existing prediction methods are mechanism-driven, incorporating numerous assumptions and simplifications that make it challenging to fully capture the complex physical processes involved in plunger gas lift technology, ultimately leading to significant errors in capacity prediction. Furthermore, engineering design factors and production system factors associated with plunger gas lift technology can contribute to substantial deviations in gas production forecasts. This study employs three powerful regression algorithms, XGBoost, Random Forest, and SVR, to predict gas production in plunger gas lift wells. This method comprehensively leverages various types of data, including collected engineering design, production system, and production data, directly extracting the underlying patterns within the data through machine learning algorithms to establish a prediction model for gas production in plunger gas lift wells. Among these, the XGBoost algorithm stands out due to its robustness and numerous advantages, such as high accuracy, ability to effectively handle outliers, and reduced risk of overfitting. The results indicate that the XGBoost algorithm exhibits impressive performance, achieving an R2 (coefficient of determination) value of 0.87 for six-fold cross-validation and 0.85 for the test set. Furthermore, to address the “black box” problem (the inability to know the internal working structure and workings of the model and to directly understand the decision-making process), which is commonly associated with conventional machine learning models, the SHAP (Shapley additive explanations) method was utilized to globally and locally interpret the established machine learning model, analyze the main factors (such as starting time of wells, gas–liquid ratio, catcher well inclination angle, etc.) influencing gas production, and enhance the credibility and transparency of the model. Taking plunger gas lift wells in southwest China as an example, the effectiveness and practicality of this method are demonstrated, providing reliable data support for shale gas production prediction, and offering valuable guidance for actual on-site production.

Published: September 2024

Single-well productivity is a crucial metric for assessing the effectiveness of petroleum reservoir development. The accurate prediction of productivity is essential for achieving the efficient and economical development of oil–gas reservoirs. Traditional productivity prediction methods (empirical formulae and numerical simulation) are limited to specific reservoir types. There are few influencing factors, and a large number of ideal assumptions are made for the assumed conditions when predicting productivity. The application scenario is ideal. However, in tight oil reservoirs, numerous factors affect productivity, and their interactions exhibit significant complexity. Continuing to use traditional reservoir productivity prediction methods may result in significant calculation errors and lead to economic losses in oilfield development. To enhance the accuracy of tight reservoir productivity predictions and achieve economical and efficient development, this paper investigates the tight reservoir in the WZ block of the Beibuwan area, considering the impact of geological and engineering factors on productivity; the random forest tree and Spearman correlation coefficient are used to analyze the main influencing factors of productivity. The back propagation neural network optimized by particle swarm optimization was employed to develop a productivity prediction model (PSO-BP model) for offshore deep and ultra-deep tight reservoirs. The actual test well data of the oilfield are substituted into this model. The analysis results of the example application yielded an RMSE of 0.032, an MAE of 1.209, and an R2 value of 0.919. Compared with traditional productivity prediction methods, this study concludes that the model is both reasonable and practical. The calculation speed is faster and the calculation result is more accurate, which can greatly reduce productivity errors. The model constructed in this paper is well suited for predicting the productivity of tight reservoirs within the WZ block. It offers substantial guidance for predicting the productivity of similar reservoirs and supports the economical and efficient development of petroleum reservoirs.

Published: September 2024

The investment estimation of the helium extraction project from natural gas is a crucial step in economically obtaining helium from both domestic and international projects. This article employs Aspen HYSYS to simulate the process and estimate the investment levels of Linde and Exxon Mobil integrated helium extraction processes. We investigate the influence of feed composition and processing capacity on investment costs and product returns. The results indicate that higher helium content of feed correlates with increased equipment investment costs and total capital cost (CAPEX), and that the Linde integrated process is significantly more sensitive to changes in helium content of feed than the Exxon Mobil integrated process. As the helium content of feed rises, the product returns of the two processes are evidently improved, leading to reduced investment payback periods. Both techniques exhibit favorable payback periods when the feed helium content exceeds 0.5 vol%. Nevertheless, elevated nitrogen content in the feed notably escalates the equipment investment costs and total capital costs. Furthermore, an increase in the processing capacity of feed gas leads to a nonlinear increase in total capital costs and annual operating costs. However, the cost per unit of helium extraction diminishes with increasing capacity. In general, the Linde integrated process requires higher separation energy consumption in comparison with the Exxon Mobil integrated process at similar processing capacities. Moreover, the sensitivity analysis shows that helium breakeven price is strongly affected by the price of both LNG and feed gas.

Published: September 2024

Faced with measurement conditions such as high-temperature forging, strict prohibition of surface contamination, and toxic environments, using the projection point of an optical target projector (referred to as an “optical projector”) as a photogrammetric target has become a necessary method of high-precision industrial photogrammetry. In connection with the current industrial demand, we have analyzed the principles of optical projectors and introduced their optical characteristics and advantages in the field of industrial photogrammetry. On this basis, a series of tests such as brightness, roundness, and so on were conducted to determine the basic properties of the optical projector. A set of performance test methods including inner coincidence accuracy and outer coincidence accuracy were proposed; the tests included industrial photogrammetry system measurement repeatability, surface measurement precision, and a comparison test with laser tracker. The test conditions used optical projection points as the photogrammetry targets. The test results showed that the coordinate measurement repeatability of the industrial photogrammetry system is 0.010 mm, and the surface measurement precision is 0.007 mm under the condition of a single optical projector station, with little difference between the results under the condition of pasting retro-reflective targets. In the process of the comparison test with laser tracker, the image quality of the black measurement object obtained is obviously inferior to other surfaces, so the analysis of the point projector is greatly affected by the color of the measured object and other conditions, which provides a reference for the measurement object and application range of the industrial photogrammetric system based on optical targets. The results demonstrate the applicability and reliability of using the optical projection point of an optical projector as target points for photogrammetry.
Operational Decisions of Construction and Demolition Waste Recycling Supply Chain Members under Altruistic Preferences
Authors: Zhu Junlin , Zhang Hao , Chen Weihong , Li Xingwei
Published: September 2024

How to efficiently and greenly dismantle abandoned buildings and reuse them is a dilemma facing the building material industry’s low-carbon objective. However, relevant studies ignore the influence mechanism of altruistic preferences of enterprises on green dismantling technology in supply chains. Driven by filling this theoretical gap, this paper firstly integrates reciprocal altruism theory and the Stackalberg game method and constructs a construction and demolition waste (CDW) recycling supply chain system consisting of a recycler and a remanufacturer, in which enterprises’ altruistic preferences are considered. The main theoretical outcomes of this paper are as follows. (1) In the case of unilateral altruism, enterprises’ altruistic preference behaviors help in increasing the green dismantling technological level and the amount of CDW recycling. Under the mutual altruism model, the influence of the recycler’s altruistic preference degree on the amount of CDW recycled hinges on the remanufacturer’s altruistic preference degree. (2) The utility of the enterprises and the green dismantling technological level are optimized under the mutual altruism model. (3) In a system of unequal power, unilateral “goodwill” by the follower will have a negative effect on their own interests; the leader plays a crucial role in facilitating equal cooperation and realizing win–win situations. This paper enriches the reciprocal altruism theory in waste management. It also helps in providing guidance for the recycler and remanufacturer in making operational decisions.
Performance Evaluation of CF-MMIMO Wireless Systems Using Dynamic Mode Decomposition
Authors: Pesantez Diaz Freddy , Estevez Claudio
Published: September 2024

Cell-Free Massive Multiple-Input–Multiple-Output (CF-MIMO) systems have transformed the landscape of wireless communication, offering unparalleled enhancements in Spectral Efficiency and interference mitigation. Nevertheless, the large-scale deployment of CF-MIMO presents significant challenges in processing signals in a scalable manner. This study introduces an innovative methodology that leverages the capabilities of Dynamic Mode Decomposition (DMD) to tackle the complexities of Channel Estimation in CF-MIMO wireless systems. By extracting dynamic modes from a vast array of received signal snapshots, DMD reveals the evolving characteristics of the wireless channel across both time and space, thereby promising substantial improvements in the accuracy and adaptability of channel state information (CSI). The efficacy of the proposed methodology is demonstrated through comprehensive simulations, which emphasize its superior performance in highly mobile environments. For performance evaluation, the most common techniques have been employed, comparing the proposed algorithms with traditional methods such as MMSE (Minimum Mean Squared Error), MRC (Maximum Ration Combining), and ZF (Zero Forcing). The evaluation metrics used are standard in the field, namely the Cumulative Distribution Function (CDF) and the average UL/DL Spectral Efficiency. Furthermore, the study investigates the impact of DMD-enabled Channel Estimation on system performance, including beamforming strategies, spatial multiplexing within realistic time- and delay-correlated channels, and overall system capacity. This work underscores the transformative potential of incorporating DMD into massive MIMO wireless systems, advancing communication reliability and capacity in increasingly dynamic and dense wireless environments.

Published: September 2024

During dental scaling in dogs under general anaesthesia, contamination of the peripheral intravenous catheter (PIVC) is unavoidable due to splatter and the generated aerosol. Bacterial contamination was compared between two commonly used PIVC placement sites. Thirty-nine client-owned dogs with a minimum length from their nose to their tail base of 50 cm were randomly assigned to receive a PIVC in either their cephalic or saphenous vein. Irrespective of the PIVC placement site, brain heart infusion agar dishes were placed in the cephalic and saphenous vein areas. Their lids were closed 0, 5, and 10 min into the procedure. Contamination was measured by counting the colony-forming units after incubation on different substrates. The data were analysed with descriptive statistics, ANOVA, and ANCOVA (p < 0.05). The cephalic vein area showed a significantly higher bacterial load than the saphenous vein area (p ≈ 0.0) regardless of the length of the dog. Furthermore, the dorsal PIVC injection ports were sampled before and after scaling, and the colonies isolated were counted and subjected to MALDI-TOF-MS for identification. The bacteria mainly belonged to the genera Staphylococcus, Neisseria, and Bacillus. Our results suggest that for dental scaling in dogs, the PIVC should be placed in the pelvic limb whenever possible to reduce the potential risk of contamination.

Published: September 2024

The article substantiates promising directions of innovative provision of agricultural production. It has been established that agricultural production remains a priority and important area of economic activity that determines the socio-economic state of the state and the level of its food security. At the same time, the growth of the country’s agricultural sector allows us to establish a stable promising trend, although achieved mainly at the expense of the crop industry. It is proved that the innovative development of agricultural production takes place under extremely unfavorable conditions, since the scientific, technical and innovative potentials of the industry are characterized by prolonged stagnation. It was found out that an important organizational and economic problem, which is caused by insufficient financing of high-quality scientific developments, is the preference of domestic agricultural producers for foreign technologies, machinery, seed material, plant protection products, fertilizers, etc. First of all, this is due to the significantly higher technical and technological characteristics of machines and mechanisms of foreign manufacturers. At the same time, innovative support for the development of agricultural production should be carried out in the context of the implementation of the state innovation policy, which should be aimed at strengthening human resources, scientific and educational, financial and investment, technical and technological potentials, the development of institutional infrastructure, financial, economic and legal regulation of innovative development of the agricultural sector.

Wages are the main source of income for agricultural workers. Since labor is a socially significant category, its legal regulation is carried out at all levels of the legislative power of the Russian Federation, which not only fix regulatory requirements, but also contain basic social guarantees and legal norms that protect the remuneration of residents and non-residents. However, each company has a certain freedom in choosing the method of payroll and employee incentives. The global social and economic importance of work and its remuneration consists in the following main functions: reproductive, stimulating and regulating. The employee performs an industrial function, the employer performs a stimulating one, and the state performs a regulatory one. The article discusses the methodological aspects of the procedure for calculating wages and insurance premiums, as well as other settlements with the staff of an agricultural organization. The subject of the study is the methodological aspects of payroll and insurance premiums, as well as the implementation of other settlements with the staff of agricultural organizations. The information base was the forms of accounting and tax reporting of agro-industrial complex organizations of the Stavropol Territory. The scientific novelty of the research consists in the development and implementation of various accounting and analytical aspects of the procedure for calculating wages and insurance premiums, as well as other settlements with the staff of an agricultural organization.

Published: September 2024

"The current study investigates the deterioration of a 100 year old bridge located in a harsh marine environment. Constructed in 1908 - 1909 the Mizen Head Footbridge was one of the oldest reinforced concrete bridges in Ireland. The demolition of the bridge in 2009 provided a unique opportunity to examine its service life and to extract samples for analysis and investigation. A review of the construction of the bridge, and its maintenance history are presented, with a view to analysing their influence on the behaviour of the concrete. Reinforcement corrosion due to chloride attack was identified. A focused study indicates that chloride contaminated constituents may have been used in the concrete mix. The study also includes details of anaerobic corrosion of reinforcement observed in the Mizen Head Footbridge. A review of anaerobic corrosion of reinforcement in concrete is presented, outlining black rust formation, characteristics and detection methods. This research may provide valuable advice and guidance for the asset management of similar structures."

"The concept of Intelligent Transportation Systems (ITS) presents new R&D challenges for the transportation and ICT sectors and is currently receiving considerable interest from the research community. The primary objective of ITS is the creation of advanced road traffic systems for improved traffic safety, efficiency, and travelling comfort. Basic vehicle and roadside infrastructure collaboration allows for an increase in efficiency and safety and acts as the foundation for an extensive service set to achieve these ITS goals. Applications such as journey planning, automatic tolling and emergency warnings, among others, are envisaged in a system which can potentially reform modern transportation. Enabling cooperation among ITS entities to the degree envisioned requires a persistent, stable and reliable underlying communications service. Communications is therefore the nervous system of the cooperative vehicular environment, and it is widely accepted that the ITS communication solution is a heterogeneous mix of complementary communication technologies for ubiquitous connectivity. Taking into account the wide array of communication technologies and plethora of proposed applications, this thesis addresses one of the major and largely unexplored challenges facing the ITS research community in relation to service and (communication management (SCM), whereby the underlying communications capability is exploited to assure satisfactory operation of deployed ITS applications. A generic SCM framework, which is directly applicable to the ISO Conditions, Air Interface for Long and Medium range (CALM) stack is presented."

Taxonomic studies in the Acanthaceae of Ethiopia and neighbouring countries reveal the presence of several previously overlooked endemic and near-endemic taxa. The Isoglossa somalensis Lindau complex is revised, resulting in the description of a new species, Isoglossa recurva Hanny & I.Darbysh. from the forests of southwest Ethiopia, and a new variety of I. somalensis, var. glandulosa Hanny, G.Hoban & I.Darbysh. from montane southeast Ethiopia. Barleria induta C.B.Clarke from Ethiopia and Eritrea, treated as B. prionitis L. subsp. induta (C.B.Clarke) Brummitt & J.R.I.Wood in the Flora of Ethiopia and Eritrea (FEE), is reevaluated and found to represent two species, with B. praetermissa I.Darbysh. described from the Tigray region of northwest Ethiopia. Finally, Hypoestes microphylla Nees is resurrected as a good species, separate from the widespread H. triflora (Forssk.) Roem. & Schult. under which it was treated as a synonym in FEE. Descriptions, tables of comparison and notes on the habitat, ecology and extinction risk for these taxa are provided. The first record of I. gregorii (S.Moore) Lindau for Ethiopia is also noted and a revised key to Isoglossa in Ethiopia is presented. The endemic Acanthaceae of Ethiopia now stands at 21 species (23 taxa), whilst an additional 23 species (24 taxa) are considered to be range-restricted near-endemics.

Published: September 2024

Una de las etapas más críticas en el desarrollo de la valía propia es la adolescencia. Aquí la autoestima es un factor determinante para el desarrollo de la personalidad, salud mental y adaptación al medio; invadir este espacio vital ocasiona repercusiones en las relaciones interpersonales, ansiedad, escasa adaptación y déficit en el rendimiento escolar, entre otros, (Ojeda & Cárdenas, 2017). El objetivo de la investigación fue la implementación de un programa de cambio de conducta para el fortalecimiento de la autoestima en adolescentes al cual se le título “Queriendo – Me” el cual, fue basado en el Modelo Trasteo rico (MT) también conocido como el Modelo de Etapas de Cambio, ha sido identificado como el más frecuentemente usado para estudiar cambio de conductas de salud. El MT describe el cambio en términos de cinco etapas y explica el cambio del comportamiento según cinco variables: etapas y procesos del cambio, balance decisorio, autoeficacia y tentación (Cabrera A, 2000). Metodología: fue de tipo cuantitativo, longitudinal y pre experimental. Muestreo probabilístico aleatorio simple con aleatoriedad estratificada donde participaron 49 estudiantes de nivel medio superior, se realizaron 14 sesiones de trabajo en base a las etapas del modelo de cambio durante un periodo comprendido de 6 meses. Los resultados se obtuvieron a partir de la colecta de datos pre y pos intervención a partir de la Escala de autoestima para adolescentes de Orlando Cerna Dorregaray 2020, 40 preguntas 0.864, y valor de Omega de Mc Donalds fue de 0.867. Los resultados muestran a partir de lo reportado por la prueba Chi=7.16; p=.007 que existe efectividad del programa para mejorar la autoestima en los adolescentes.

En esta investigación nos propusimos analizar la representación de los roles de género a partir de las ilustraciones de los libros oficiales de Lenguaje en Colombia para los grados Sexto, Séptimo, Octavo y Noveno. Se eligió el Análisis Crítico del Discurso desde un enfoque feminista (ACDF). El corpus fueron las imágenes presentes en los libros de texto Vamos a aprender lenguaje de sexto a noveno. Se identificaron las estrategias discursivas y se explicó qué develan estas estrategias. Se analizaron 762 imágenes. Encontrando un desequilibrio en la representación de género, con un 71% de figuras masculinas y un 29% de figuras femeninas. Se observó una distribución espacial y profesional marcada por estereotipos de género y raciales, con una doble marginalización de las figuras femeninas, especialmente las indígenas y afrodescendientes. Se concluye que los libros de texto reflejan desigualdades de género, perpetúan estereotipos y sesgos de género que limitan las percepciones y oportunidades de las mujeres, manteniendo y reproduciendo jerarquías sociales que afectan a las mujeres. Es esencial considerar la diversidad étnica de Colombia para avanzar hacia una representación más equitativa y justa en la sociedad, reconociendo la importancia de abordar críticamente el contenido de los libros de texto.

Introdução: O parto prematuro, definido como nascimento antes das 37 semanas de gestação, é um problema significativo de saúde pública com impactos profundos na saúde neonatal. As causas e fatores de risco para partos prematuros são variados e podem afetar gravemente o desenvolvimento do recém-nascido. Objetivos: Revisar as causas e fatores de risco associados aos partos prematuros, identificando elementos críticos e lacunas no conhecimento atual para melhorar as estratégias de prevenção e manejo. Métodos: Trata-se de uma revisão na literatura científica, usando a base de dados SciELo. Resultados e discussão: A revisão da literatura revela que os principais fatores de risco para partos prematuros incluem condições médicas como hipertensão e diabetes gestacional, complicações durante a gravidez, e características sociodemográficas, como gravidez na adolescência e baixo status socioeconômico. A falta de acesso e a baixa qualidade dos cuidados pré-natais são determinantes significativos, exacerbando os riscos. Conclusão: Para reduzir a incidência de partos prematuros, é crucial melhorar o acesso e a qualidade dos cuidados pré-natais, além de realizar triagem e intervenções personalizadas baseadas nos fatores de risco identificados.
The Impact of Household Debt on Domestic Violence (DV) Against Children in Indonesia
Authors: Maulitfiani Anjar , Handayani Dwini
Published: September 2024

Financial difficulties within a household could contribute to cases of domestic violence (DV). This study investigates the correlation between household debt and occurrences of domestic violence towards children in Indonesia. The study employs a quantitative methodology, notably utilising multinomial logistic regression analysis. Evidence suggests that households with several forms of debt are more prone to exhibiting both psychological and physical domestic violence against children, in contrast to households without domestic violence. This association maintains its significance even after taking into account control variables, such as the age of the spouse, the level of education of the head of home, the spouse's level of education, the size of the household, the perception of domestic violence, the schooling status of the children, and the age of the children are statistically associated with psychological, physical, and both types of domestic violence against children. Policymakers should assess household loan repayment capacity to limit lending to those at risk of financial struggle, while the government should implement parental education programs to raise awareness of child abuse and encourage non-violent parenting techniques.

Indonesia and Timor Leste have the same land area; these countries are located on Timor Island. It encourages interaction between regions, which can have positive or negative impacts. The adverse effects of the two countries' interaction must be minimized by formulating a strategy for developing border areas, especially village areas that directly border neighboring countries. This research aims to identify rural border communities' social and economic interactions and formulate development strategies for rural border areas in the Malaka and Belu Regencies. This research uses a qualitative research approach. The data collected includes a description of the social and cultural interactions carried out by rural communities and factual conditions that constitute strengths, weaknesses, threats, and opportunities in developing rural border areas. The analysis results explain that the interactions between rural borders include socio-cultural and economic interactions in trade activities. The strategy for developing rural border areas is to increase defense and security and maintain social cohesion in border areas; strengthen local potential in each village; encourage rural economic activities (BUMDes or Cooperatives) to grow and develop, and export rustic products; form clusters in rural border areas with the same potential; strengthening cooperation networks with higher education, the private sector and non-governmental institutions in improving and developing rural border areas; strengthening rural economic activities with rural border markets; increasing rural community participation in border area maintenance efforts; as well as improving access to basic infrastructure, in particular electricity, roads, water and telecommunications.
Teaching and learning for sustainable futures: Reclaiming, collaboration and empathy
Authors: Berman Kim Shelley
Published: September 2024

Introducing community engagement to my annual class of Visual Art honours students has become increasingly challenging. There is a healthy resistance to the perception of ‘cultural tourism’, and students are sensitive to the idea of entering a community as voyeurs with the perception of privileged “saviours”. I offer a particular example of an emerging annual exchange with the African Reclaimers Organisation (ARO), who have partnered with the University of Johannesburg (UJ) in a range of projects that can add value to upcycling of collected and sorted waste products. The pervasive news of corruption, violence, and rolling blackouts undermines well-being and increasingly perpetuates despair, apathy, or distraction. In this climate, a question of response in an educational environment is pertinent. How does one teach and learn about sustainable futures? How can educators foster empathy, agency, and activism among students? This article draws on ecology activist and scholar Dylan McGarry’s expanded concept of transgressive social learning using skills transfer through an apprenticeship, which is helpful in framing a model of teaching and learning based on social exchange.  Including selected student reflections, the paper considers methods and practices that model ways to develop various forms of personal and social agency through exploring empathetic encounters.
