Esta investigación analiza los factores que motivan y condicionan la continuidad laboral de los adultos mayores en La Serena, en un contexto de envejecimiento poblacional acelerado en Chile y la Región de Coquimbo. Basándose en datos estadísticos, se observa un aumento significativo en la proporción de adultos mayores, planteando desafíos en su inclusión laboral y bienestar económico.

La investigación busca comprender cómo las características demográficas, motivaciones individuales y políticas públicas influyen en sus decisiones laborales tras la jubilación.

El objetivo general es analizar los factores que inciden en la continuidad laboral de los adultos mayores. Se identifican características demográficas y laborales, se exploran motivaciones y barreras, y se evalúan políticas públicas para proponer estrategias que mejoren su inclusión laboral y calidad de vida.

La metodología empleada es de enfoque mixto con un diseño exploratorio secuencial (DEXPLOS), aplicando entrevistas semiestructuradas y focus groups en la parte
cualitativa, complementados con encuestas para los datos cuantitativos.

Los hallazgos preliminares señalan que las principales motivaciones incluyen la necesidad económica, la autorrealización y el deseo de mantenerse activos. Sin
embargo, enfrentan barreras como discriminación por edad, condiciones laborales desfavorables y falta de oportunidades. Las políticas locales son percibidas como insuficientes para atender integralmente sus necesidades.

Esta investigación propone estrategias inclusivas que valoren la experiencia de los adultos mayores, fomentando su participación en el mercado laboral y promoviendo su bienestar integral.

When graphs are used to solve the problem of determining the shortest route, it has become a common topic of discussion. Typically, these solutions are used to optimize aspects such as travel time. Using the Floyd-Warshall and A* algorithms, this research assists the community, particularly visitors, in determining the most sensible route from the Rimbo Panjang front gate to each building at UIN Suska Riau. The calculation technique is performed manually. The algorithm developed by Floyd Warshall yields more efficient calculation results. The results of calculations conducted by both algorithms are the same and have the correct minimum weight value. In a comparative analysis test, Warshall's algorithm is more efficient than the A* algorithm because it has a higher minimum weight that has been effectively tested for distance, trajectory, and distance. A comparison of the Floyd-Warshall algorithm and the A* algorithm reveals that the Floyd-Warshall algorithm determines the shortest route more effectively.

Authors: Agustina Anjel , Affandi Pardi
Published: January 2025

Dengue Hemorrhagic Fever (DHF) is a disease caused by dengue virus infection through the bite of the Aedes Aegypti mosquito. The high number of cases of DBD from year to year has become a major health problem in Indonesia. DBD can be modeled using mathematical modeling to understand the dynamics of disease spread through the stability of the equilibrium point and optimal control of the problem of DBD transmission. The DBD model is classified into 2 types of classes: the human population class and the mosquito class. There are three subclasses for the human population class: the susceptible population, the infected population, and the recovered population. Meanwhile, the mosquito population class is divided into three subclasses, namely the aquatic population, the susceptible population, and the infected population. The aims of this study were to determine a mathematical model for the spread of Dengue Hemorrhagic Fever, to reconstruct the model, to determine the optimal control form for DBD, and to perform numerical simulations. The result of this study is the formation of the SIR-ASI model for DBD. Based on this model, two equilibrium points are obtained, namely a disease-free equilibrium point and an endemic equilibrium point. Then the basic reproduction number (R_0 ) is obtained through the Next Generation Matrix method.

Fuel Oil is a commodity that plays a vital role in all economic activities. Fuel oil (BBM) is energy that needs to be subsidized because the price of fuel is heavily influenced by external factors, namely the price of crude oil on the world market. Fuel subsidies from the government distributed by Pertamina are still limited to the types of kerosene, diesel and premium as the energy consumed by the public. The impact of the increase in world oil prices which resulted in the government reducing subsidies for domestic fuel affected the fares of public transportation, including public transportation in cities. In-town public transportation is a mode of transportation that connects one area to another in the city. Research on the amount of fares for inner-city transportation, especially with fluctuations in fuel price increases, needs to be examined to see the relationship between the percentage increase in fuel prices and the increase in public transport fares in the city. In this research, the route under review is the city center route – Padang.

The inverse of matrix is one of the important properties of matrix. This properies, especially singular matrix, has been developed by Moore and continued by Penrose. Then, this inverse called Moore-Penrose inverse. The Moore-Penrose invers criteria can represent a projection on a vector space V along W with V and W are orthogonal to each other or can written with W=V^⊥ which is called orthogonal projection matrix on V. This research will present lemmas and theorems related to the Moore-Penrose invers construction of the multiplication matrix. Then, a square matrix is an orthogonal projection matrix on a vector space V if and only if it satisfies two conditions, that are idempotent and symmetric. These two properties are satisfied by matrices I-A^+ A and I-AA^+ which respectively are orthogonal projection matrices on Ker(A) and Ker(A^' ). As a result, the Moore-Penrose inverse A^+ can be constructed from a square matrix A which is an multiplication of several matrices and fulfills certain properties.

The included articles explore theological, historical, and social dimensions of this relationship, addressing topics such as the catholicity of the Church, ecumenical challenges, and anti-ecumenical trends in Orthodoxy. Contributions from theologians of various Christian traditions, including analyses of "sister Churches" and reflections on the mystery of Ecclesia, emphasize the effort to understand diversity within unity. This publication provides a valuable contribution to the debate on the contemporary understanding of the Church and its mission in the world.
Synergistic effects of SCMs and fibers on plastic shrinkage control of sustainable concrete
Authors: James Jerison Scariah , John Elson
Published: January 2025

The construction industry’s reliance on reinforced cement concrete presents environmental concerns, including resource depletion and pollution. This study investigates sustainable alternatives by using industrial by-products, such as fly ash, blast furnace slag, and silica fume as partial replacements for ordinary Portland cement in concrete. In addition, it examines the integration of both synthetic and natural fibers to control plastic shrinkage, a critical issue for concrete durability. Through an experimental approach aligned with ASTM 157, a total of 25 concrete mixtures were tested, incorporating 30% fly ash, 40% ground granulated blast furnace slag, and 10% silica fume by mass, along with various fibers, including steel, polypropylene, glass, coir, sisal, and jute. The results indicate significant enhancements in concrete’s mechanical properties and a reduction in plastic shrinkage. Adding fibers notably increased shear resistance and reduced shrinkage by up to 40%, with steel and polypropylene fibers specifically decreasing crack dimensions by 25% and 35%, respectively. Furthermore, the use of supplementary cementitious materials (SCMs) decreased shrinkage by an additional 25%, significantly improving durability and performance. The combination of SCMs and fibers presents a promising strategy for creating environmentally friendly and resilient concrete.

The Fed's Discount Window in "Normal" Times
Authors: Ennis Huberto M. , Klee Elizabeth
Published: January 2025

We study transaction-level data of bank borrowings at the Federal Reserve's discount window from 2010 to 2019. We merge these data with quarterly information on bank balance sheets and income statements. To aid in the interpretation of our empirical analysis, we also develop a detailed model of the decision of banks to borrow from various sources, including the discount window. The objective is to contribute to a better understanding of the reasons why banks use the discount window during ``normal'' times---periods of relative calm in financial markets. Consistent with our model, we find that borrowing from the discount window is tightly linked to the composition of banks' balance sheets. Most importantly, banks holding less reserves tend to borrow more often (and more) from the Fed's discount window. Similarly, banks with more expensive and fragile liabilities, and less marketable collateral, are also more likely to borrow from the Fed.
Measured Inflation and the New-Keynesian Model
Authors: Christiano Lawrence J. , Eichenbaum Martin , Johannsen Benjamin K.
Published: January 2025

Researchers typically compare inflation in the new Keynesian (NK) model to published inflation measures constructed from indices like the CPI. Inflation in the standard NK model without price indexation is bounded above. The model analogue of fixed-weight inflation measures, like the CPI, is not. When inflation is in the range of values observed after 2021, there is a substantial difference between model-based and fixed-weight measures of inflation. This finding poses a challenge to using linear approximations to the NK model in environments with moderately high inflation and implies that analysts should construct data-consistent model analogues when assessing the NK model.
A Market Interpretation of Treatment Effects
Authors: Minton Robert , Mulligan Casey B.
Published: January 2025

Markets, likened to an invisible hand, often appear to contradict econometric assumptions that rule out spillovers of one person’s treatment on another’s outcomes. This paper provides a simple statistical framework highlighting that controls are indirectly affected by the treatment through the market. Further, the effect of the treatment on the treated reveals only part of the consequence for the treated of treating the entire market. When combined with economic theory, our framework leads to a new application of Marshall’s Laws of Derived Demand that relates econometric estimates of treatment effects in the marketplace to the substitution and scale effects of demand theory. We show how treatment-effect estimators can diverge – both in magnitude and direction – from the causal effects of treatment on the treated or counterfactual policies treating all market participants. The framework shows how the consequences of targeted treatments reveal the effects of marketwide treatments, and the role of market frictions in that inference. Examples from labor, public finance, economic geography, development, and the macro literature on the “missing intercept” are provided.
Measuring the Euro Area Output Gap
Authors: Barigozzi Matteo , Lissona Claudio , Luciani Matteo
Published: January 2025

We measure the Euro Area (EA) output gap and potential output using a non-stationary dynamic factor model estimated on a large dataset of macroeconomic and financial variables. From 2012 to 2023, we estimate that the EA economy was tighter than the European Commission and the International Monetary Fund estimate, suggesting that the slow EA growth is the result of a potential output issue, not a business cycle issue. Moreover, we find that credit indicators are crucial for pinning down the output gap, as excluding them leads to estimating a lower output gap in periods of debt build-up and a higher gap in periods of deleveraging.

El presente artículo relata la implementación de la accesibilidad digital para personas mayores y con discapacidad física, posibilitando el ejercicio efectivo de la ciudadanía de estos grupos en la revisión del Plan Director Estratégico de São Paulo, iniciada en 2021. La metodología utilizada es cualitativa, incluyendo levantamiento bibliográfico para el fundamento teórico, análisis documental y enfoque ex-post-facto, destacando la Acción Civil Pública nº 1022650-93.2022.8.26.0053, que se tramitó en la 16ª Vara de la Hacienda Pública de la Capital. Esta acción, promovida por la Defensoría Pública del Estado de São Paulo, buscó asegurar, a través de la tutela jurisdiccional, el ejercicio de la ciudadanía de los grupos excluidos.El estudio también establece una analogía con Medellín, en Colombia, en cuanto a la política de inclusión y la actuación del Poder Judicial. La relevancia académica reside en demostrar que, aunque estos grupos están legalmente protegidos, inicialmente fueron excluidos del ejercicio de la ciudadanía debido a barreras de información, comunicación y tecnología. Sin embargo, tras la acción judicial, la tecnología se convirtió en un medio de accesibilidad.Se constató que la actuación del Poder Judicial fue eficaz, recomendando instrumentos tecnológicos adicionales a los requeridos por la Defensoría y el Ministerio Público, lo que permitió la participación de estos grupos en las audiencias digitales de la Revisión del Plan Director Estratégico. Finalmente, el Poder Judicial homologó un acuerdo entre las partes, comprometiendo al Municipio a mantener la accesibilidad digital para personas mayores y con discapacidad en el proceso de revisión del Plan Director Estratégico.

Per poder avanÃ§ar en noves dianes terapÃ¨utiques que millorin aquestes malalties, Ã©s necessari conÃ¨ixer millor la biologia del teixit adipÃ³s i els seus components. El teixit adipÃ³s blanc, a mÃ©s a mÃ©s d'emmagatzemar la major part de les reserves energÃ¨tiques, Ã©s capaÃ§ de tenir activitat metabÃ²lica i endocrina. Cal tenir en compte que un metabolisme lipÃ­dic adequat en l'adipÃ²cit tambÃ© Ã©s clau per aconseguir un equilibri en l'homeÃ¨stasi del metabolisme glucÃ­dic en l'Ã©sser humÃ . En aquest treball hem analitzat el paper de dues proteÃ¯nes implicades en la lipÃ²lisi del teixit adipÃ³s: d'una banda, el canal de glicerol aquaporina 7 (AQP7), i per altra, l'adipoquina glicoproteÃ¯na Zinc-? 2 (ZAG), en el context de l'obesitat, la sÃ­ndrome metabÃ²a i la DM2.

Authors: Nemani Sravan
Published: January 2025

This study examines the role of transformational leadership in developing essential 21st-century skills like innovation, adaptability, problem-solving, and digital literacy within educational institutions. Using a cross-sectional survey design, data was collected from educators in public and private schools. The survey assessed leadership practices, including innovation inspiration, professional development opportunities, and guidance on adapting teaching strategies. T-tests and correlation analyses were used to explore the relationships between leadership and educational outcomes. Results indicate that transformational leadership significantly enhances STEM education, with 62.67% of respondents inspired to innovate and 56.67% reporting improved confidence in STEM teaching. No statistically significant differences were found between public and private schools, suggesting these practices are universally applicable. The correlation analysis revealed a moderate positive correlation (r = 0.495, p < 0.001) between fostering adaptability and preparedness for the workforce, underscoring the critical role of leadership in equipping students with the skills needed for success in the 21st-century job market. The findings underscore the critical role of leadership in equipping students with the skills needed for the 21st-century workforce and highlight the importance of fostering lifelong learning and adaptability. Future research should explore long-term impacts and applicability across diverse educational contexts.

Human Security and Governance: Indonesian Illegal Migrant Workers in Malaysia
Authors: Ahmad Rahimi , Khairi Aizat
Published: January 2025

This study investigates the migration of Indonesian workers to Malaysia, with a specific focus on irregular migrants. Despite Indonesia’s economic growth, factors such as unemployment, low wages, and limited opportunities in rural areas continue to drive migration. Utilising an integrated framework that combines economic incentives and human security dimensions, this research analyses seven components of human security: economic, food, health, social, personal, community, and political security. Primary data, including face-to-face interviews with key stakeholders, underscores this phenomenon's personal and systemic dimensions. Findings reveal that socio-economic challenges in Indonesia act as push factors, while wage disparities and economic prospects in Malaysia serve as pull factors. However, these benefits come with challenges, such as xenophobia, integration difficulties, and societal instability in the host country. This study highlights the limited efficacy of enforcement measures like deportations and suggests policy reforms addressing root causes. This research contributes to understanding irregular migration governance within a human security framework, offering insights into Malaysia’s policy responses.

Published: January 2025

Currently, biomaterials are increasingly in demand in medicine and are fundamental components of tissue engineering. The necessary factors of these materials to ensure their ability to effectively function in the human body are biocompatibility, bioactivity, bioresorption and non-toxicity. An ideal implant should have a number of physical, chemical and biological characteristics to stimulate cell proliferation and promote tissue formation. Bioresorbable polymers have advantages for tissue engineering applications due to a wide range of mechanical properties combined with sufficient chemical inertness and degradation rate. Given the increasing number of studies in the field of biomaterials for medical applications, the purpose of this review is to examine recently developed implantable materials. In this work, emphasis is placed on the development of the composition of polymers that determine the characteristics of future bioresorbable materials, as well as on the choice of optimal parameters and a method for their preparation.
Synthesis of Si/G Composite Anodes for Lithium-Ion Batteries: A Review
Authors:   ITMO University, Russia, Azaizia A. , Dorogov M.V. ,   ITMO University, Russia
Published: January 2025

By overcoming significant performance constraints, recent developments in silicon/graphene (Si/G) composite anodes have shown promise for revolutionizing lithium-ion batteries. Although silicon has a remarkable theoretical capacity, structural instability results from its large volume growth during cycling. Though it lacks the potential for high-energy applications, graphene, which is well-known for its exceptional mechanical flexibility and electrical conductivity, enhances the qualities of silicon. By combining these materials, Si/G composites have demonstrated impressive gains in rate performance, structural stability, and capacity retention, providing a promising avenue for next-generation energy storage technologies. High-performance Si/G composites have been made easier to create by advancements in scalable synthesis processes like sol-gel processing, chemical vapor deposition, sophisticated self-assembly techniques and Hummer’s method. With an emphasis on cutting-edge silicon-based anodes, carbon composites, and workable techniques for acquiring and altering silicon anodes, this review seeks to examine the most recent developments and unsolved issues in the advancement of lithium-ion batteries. In order to address the needs of contemporary high-capacity applications and expedite the integration of Si/G composites into next-generation energy storage systems, these insights are crucial.
Studying microtoponymy in Belarus: achievements over nearly 60 years
Authors: Shkliaryk Vadzim
Published: January 2025

The article presents an assessment of the work done by Belarusian researchers for almost 60 years in the field of microtoponymy studies. This analysis was made possible by the creation of an electronic bibliography on Belarusian microtoponymy at Jakub Kolas Institute of Linguistics of the National Academy of Sciences of Belarus. Due to the lack of such publication database previously, researching the names of small geographical objects in the country was complicated. Until recently this process had been disorganized, but today there are grounds and opportunities to rectify such situation.
An important feature of the electronic bibliography on Belarusian microtoponymy is the availability to select fields as “Region” and “District”, which can be used to sort the publications. This option makes it possible to assess what has been done in certain regions of Belarus in particular. In other words, this publication database can be used to identify the locations where names of small geographical objects have not been collected and/or have not been researched.
Moreover, the electronic bibliography on Belarusian microtoponymy revealed that for almost 60 years only four candidate dissertations and only two monographs have been devoted to local microtoponyms in the country. However, the low attractiveness of microtoponyms as an object of research in Belarus is partially rectified by a number of comprehensive dissertations and monographs where the names of small geographical objects are analyzed along with oikonyms and/or hydronyms.
