War on Palestine: How the fates of Gaza and Julian Assange are sealed together
Authors: Cook Jonathan
Published: July 2024

Commentary: Were they being properly reported, two critically important court hearings in February 2024, in London and The Hague, would expose the US ‘rules-based order’ as a hollow sham. Both posed globe-spanning threats to our most basic freedoms. Neither received more than perfunctory coverage in Western establishment media such as the BBC. One was a week-long hearing by the International Court of Justice (ICJ) over a United Nations General Assembly request for an advisory opinion over Israel’s illegal occupation of the Palestinian territories and the other was a last-ditch appeal of WikiLeaks founder Julian Assange against efforts by the United States to extradite him so that he can be locked away for the rest of his life.
EDITORIAL NOTE: After the editorial of Pacific Journalism Review and the lead article in this edition (Vol 30, No 1&2) about the fate of WikiLeaks founder Julian Assange were printed, the Australian journalist was set free and he arrived back in Australia after a plea bargain. The winner of his country’s Walkley Award for journalism excellence, Assange was freed by a US federal court in Saipan, Northern Mariana Islands, on 26 June 2024 after a plea bargain to plead guilty to one charge of violating the US Espionage Act and the judge sentenced him to 62 months, jail time already served in the UK on remand. His 14-year struggle for freedom was over, but his lawyers say they will press for a full US presidential pardon.
Time to rethink 'watchdog' journalism in the Pacific
Authors: Seneviratne Kalinga
Published: July 2024

For more than five decades, ‘Watchdog Journalism’ has been taught as the yardstick for a free media. With the so-called ‘mainstream’ media becoming increasingly commercialised—both in a global scale and domestically—and with the media being primarily owned by business conglomerates, the ‘watchdog’ model has created a journalism culture that is too adversarial and creates conflicts rather than helping to solve today’s problems/conflicts. A new paradigm of watchdog journalism is needed where the media is able to hold powerful players to account for facilitating the development/livelihood needs of communities, especially those in the margins of society. This new paradigm of journalism needs to focus on ‘development rights’ rather than ‘human rights’ taking into account many aspects of the United Nations’ Sustainable Development Goals (SDGs). The SDGs should be looked at in terms of a new definition of human rights where the journalist could play a similar role to that prescribed in ‘watchdog’ journalism theory, but looking for solutions rather conflicts, and include a larger field of stakeholders which need to be made accountable such as governments, big business and particularly conglomerates—even NGOs and faith-based organisations. This watchdog role needs to be applied to trade agreements and other treaties, including those addressing climate change.  To develop a new journalism culture to address these issues, media training programmes in the Pacific need to rethink their strategies and examine how to promote independent social media models that are economically and sustainably viable.

Spray drying merupakan teknologi pengolahan produk yang digunakan untuk mengubah bentuk cairan menjadi bentuk partikel kering dengan media semprot pengeringan panas. Proses pengeringan yang singkat dengan kondisi operasional yang terkontrol dapat mempertahankan temperatur droplet agar tetap rendah sehingga dapat menerapkan temperatur udara pengeringan yang tinggi tanpa mempengaruhi produk. Temperatur produk yang rendah dan waktu pengeringan yang singkat memungkinkan metode spray drying dapat digunakan untuk pengeringan produk yang sangat sensitif terhadap panas dan mempertahankan berkualitas produk seperti warna, rasa, dan nutrisi. Banyak kajian eksperimental maupun numerikal telah dilakukan untuk mengetahui karakteristik proses spray drying termasuk membandingkan hasil eksperimental dan simulasi, dan menghasilkan prediksi profil kecepatan dan temperatur selama proses spray drying menggunakan simulasi komputasi dinamika fluida. Penelitian mengenai pengaruh temperatur pada proses spray drying telah dilakukan, dalam penelitian tersebut menyatakan bahwa semakin tinggi temperatur pengeringan, maka semakin rendah nilai moisture content dan water activity pada produk yang dihasilkan. Dalam penelitian ini, parameter pengeringan yang digunakan adalah temperatur udara masuk pada spray dryer dimana udara tersebut akan dipanaskan menggunakan pemanas udara terlebih dahulu. Simulasi dilakukan secara numerik dengan pemodelan 3 dimensi menggunakan Computational Fluid Dynamics (CFD). Hasil yang diperoleh mempunyai nilai error sebesar 3% dibandingkan dengan data eksperimen. Semakin tinggi temperatur heater maka akan menghasilkan temperatur outlet yang tinggi pula. Temperatur tertinggi berada pada area heater dan temperatur dinding pemanas udara sangat mempengaruhi proses pemanasan udara. Udara setelah melewati heater 3 mempunyai nilai temperatur yang paling tinggi dibandingkan heater-heater sebelumnya dan bahkan heater-heater setelahnya. Dari kesimpulan tersebut, alat pemanas udara harus dievaluasi ulang terutama dari segi desain dan sistem kerjanya untuk meningkatkan efisiensi pemanasan udara.

VOICES OF RUDARI WOMEN FROM FILIAŞI (ROMANIA) IN THE CONTEXT OF CONVERSION TO PENTECOSTALISM
Authors: GIRIGAN Gabriel
Published: July 2024

Voices of Rudari women from Filiaşi (Romania) in the Context of Conversion to Pentecostalism. The present article examines conversion to Pentecostalism among Rudari women in post-socialist Eastern Europe. The case study focuses on a Rudari ethnic community located in a small town in southern Romania and shows that Rudari women assume a dual role: one involves preserving the interplay between Pentecostalism and local culture, while the other entails initiating conversion among men. Women facilitate conversion through visions, dreams, or manifestations of illness, which position them as gatekeepers who translate Pentecostalism into the local cultural context. Furthermore, women serve as guides for men undergoing conversion, playing a vital role in bridging the gap between Rudari traditions and the Pentecostal culture. They demonstrate proficiency in interpreting Pentecostal ecstatic phenomena within their predominantly male community, with their voices serving as mediators throughout the conversion process (Brusco, 2010). Similarly, women act as “therapists,” facilitating men’s conversion and addressing issues related to the transformation of traditional notions of masculinity.
Voci ale femeilor rudărese din Filiași (România) în contextul convertirii la penticostalism. Articolul de față prezintă convertirea la penticostalism în rândul femeilor dintr-o comunitate de rudari în contextul postsocialismului est-european. Studiul de caz prezintă o comunitate etnică de rudari dintr-un oraș mic din sudul României. Argumentez că femeile rudărese au un dublu rol în comunitate, primul de conservare a dualismului dintre penticostalism și cultura locală și al doilea de inițiere a convertirii în rândul bărbaților. Femeile alimentează convertirea religioasă prin viziuni, vise sau semne de boală. Toate aceste condiții prealabile au facilitat devenirea lor ca interprete ale traducerii penticostalismului în cultura locală. Mai mult decât atât, femeile devin astfel călăuze ale convertirii bărbaților. Ele joacă, de asemenea, un rol important în medierea celor două lumi, tradițiile Rudari și noua cultură penticostală. Ele sunt capabile să descifreze semnele extatice penticostale într-un context comunitar dominat de bărbați, vocile femeilor devenind astfel un mediator în procesul de convertire (Brusco, 2010). În mod similar, femeile acționează ca „terapeute” în contextul procesului de convertire și transformare a machismului bărbaților.

Actividad política y diplomática de las Cortes de Navarra y los Estados de Bearne: los años iniciales del reinado de Catalina I y el inicio de la “guerra jurídica” con el rey de Francia
Authors: Adot Lerga Álvaro
Published: July 2024

Las asambleas representativas de Navarra y Bearne desarrollaron un activo papel político y diplomático entre el último tercio del siglo XV y comienzos del XVI. Su importante tarea de asesoramiento a los reyes de Navarra en importantes temas de índole internacional fue acompañada de una actividad política y diplomática realizada ante embajadores de otros reinos, especialmente en tiempos de inestabilidad y confrontación política, llegando a emitir cartas de creencia e instrucciones a embajadores navarros y bearneses, como sucedió en el año 1507, momento de grave conflicto político entre las monarquías navarra y francesa.
El testamento de García Fernández (1241): un ejemplo de la concepción de la muerte de la nobleza castellana en el siglo XIII
Authors: Domingo Pérez Javier
Published: July 2024

El presente estudio analiza la mentalidad respecto a la muerte de los estamentos privilegiados, especialmente de la nobleza, y la gestión y reparto de sus posesiones, a través del estudio del testamento de García Fernández, mayordomo mayor de Fernando III y tutor de Alfonso X el Sabio. Para ello, se hará un análisis diplomático de esta tipología documental, comparando las últimas voluntades de distintos miembros de la aristocracia castellana bajomedieval, así como del estado de la cuestión respecto a esta problemática; para terminar analizando las disposiciones recogidas en el testamento del citado García Fernández, del que también analizaremos su figura. Se llega a la conclusión de que los individuos que formaban la cúspide del régimen señorial castellano del siglo XIII hacían grandes esfuerzos económicos y espirituales por la salvación de su alma. Además, puesto que el testamento que se estudia no es un original, sino una copia del siglo XVI, se estudia detenidamente la tradición documental del mismo.
Administrar la indulgencia y servir a la Corona: Andalucía, la bula de Cruzada y la guerra de Granada (1482-1492)
Authors: Perea Moreno María Inocencia
Published: July 2024

La última guerra contra Granada (1482-1492) supuso un punto de inflexión en los ingresos obtenidos por la renta extraordinaria de la cruzada. El análisis de las cuentas que rindieron los distintos tesoreros y comisarios encargados de su gestión en Andalucía permite realizar una aproximación no solo a la estructura que presentó este recurso, sino también acercarnos al perfil de los recaudadores. Por tanto, los objetivos de este artículo pasan por estudiar la extracción profesional de los agentes implicados, así como las distintas vías de acceso a este oficio, de forma que nos ayude a entender los intereses que estaban detrás de la gestión de un recurso que en estos momentos iniciaba el camino a convertirse en uno de los principales instrumentos financieros de la Monarquía Hispánica.
Timens diem mortis meae: el testamento de Urraca de Castilla, reina de Portugal (1214)
Authors: Perrino Victoria
Published: July 2024

Los testamentos son una fuente básica de conocimiento por ser documentos individuales, cuyos formulismos son reflejo del sistema de creencias y la mentalidad colectiva de una época incardinada en unas coordenadas espaciales y temporales específicas. Por tal motivo, se analizará el testamento de la reina Urraca de Castilla, cuya trayectoria vital ha sido tan tímidamente abordada por la historiografía, a fin de profundizar en el conocimiento de su coyuntura circunstancial y, con ello, incrementar tanto la información sobre la creencia en la salvación del alma a través de las obras pías como las dinámicas de relación entre el poder regio y el eclesiástico en la Plena Edad Media.
Autocracy Rising. How Venezuela Transitioned to Authoritarianism
Authors: Martí I Puig Salvador
Published: July 2024

La obra de Javier Corrales, Autocracy Rising. How Venezuela transitioned to Authoritarianism, no es una más entre la ya extensa (a pesar de reciente) literatura sobre el tema de la desdemocratización. Si bien esta temática nos retrotrae al libro de Juan José Linz –de lectura inexcusable– titulado The Breakdown of Democratic Regimes (cuya primera edición es de 1978), es preciso indicar que después de la “tercera ola de democratización” muchos académicos dejaron a un lado los estudios sobre la posible involución de las nuevas –y viejas– democracias hacia regímenes autoritarios. Sin embargo, este tipo de análisis empezaron a desarrollarse cuando algunos avispados politólogos vieron que las elecciones de las democracias neófitas (o autoritarismos que sólo querían democratizarse epidérmicamente) no siempre eran limpias ni competitivas. Así aparecieron los excelentes trabajos de Andreas Schedler, en los que se nos señalaba que no era “oro electoral” todo lo que relucía y, ya en 2006, escribió la obra Electoral Authoritarianism: The Dinamics of Unfree Competition. Luego, poco a poco, llegó una avalancha de ensayos sobre este tipo de episodios y el tema se volvió moda hasta el extremo de que la obra de How Democracies Die, de Steven Levitsky y Daniel Ziblat, se ha convertido en uno de los best sellers de la politología de la última década.

Autobiografías que son de varios: un poema autobiográfico de Octavio Paz con William Wordsworth de Figurante
Authors: Navarro Ramírez Sergio
Published: July 2024

Este artículo examina la importancia de El preludio de William Wordsworth para la composición de Pasado en claro, de Octavio Paz. A partir de esta influencia, la investigación estudia ambos poemas autobiográficos en relación con las teorías lingüísticas de los autores. En concreto, se ponderan los diversos efectos que para la escritura autobiográfica tienen la doctrina de la asociación y de las correspondencias —en el caso de Wordsworth—, y el influjo del estructuralismo y sus derivas —en el caso de Paz. La constantereferencia y contraste con William Wordsworth servirán para analizar la autobiografía poética de Paz como punto de encuentro y desencuentro entre lo individual y lo político, lo íntimo y lo histórico.

Mechanism of strategic remoulding of high-dimensional industrial eco-economy and the reconstruction of carbon neutral industrial chain
Authors: Shen Zizhen , Tang Gennian , Lin Zhenpao , Wang Jinggang , Gao Yueting
Published: July 2024

Considerable changes in the international society, fierce international competition and unpredictable economic changes are currently observed. Since then, the epidemic has had a far-reaching impact, and many industrial and supply chains have suffered from ‘broken chains’, ‘blocked chains’ and ‘poor chains’. The European Union (EU) has also sounded the alarm on China’s ‘card neck’ restrictions and ‘entity list’. Therefore, pursuing the integration of dual carbon landscape planning and industrial chain and addressing the key high-dimensional ecological economy ‘neck-choking’ problem path have become important tasks. National ministries and commissions have issued a number of documents to promote the integration and innovation of the industrial chain, high-, medium- and low-dimensional enterprises, and guide such industries to take the road of ‘high dimensional’ development. This paper takes eco-economic strategy as the starting point to reshape the systematic theoretical analysis framework of economic strategy mechanism. In response to the high-dimensional industrial transformation adaptation path and carbon neutral industry chain development model of the academic inquiry, the ‘profit model’ is set as the core and configuration complementary, alternative management thinking analysis path and model. Simultaneously, the high-dimensional industrial eco-economic industrial chain adaptation path is identified. The effects of high-dimensional industry ‘five forces’, ‘colouring map’ and ‘new tools’ are explored and then integrated and refined to improve the implementation efficiency of the carbon neutral industrial chain. Finally, focusing on the high-dimensional ecological economic strategy reshaping mechanism, the formation of sustainable development of the ‘carbon neutral’ industrial chain, unified standards and the realisation of the chain length system is investigated.

Published: July 2024

The characteristics and hydrogen reduction behavior of W-0.8 wt% Ni-0.4 wt% Cu powder synthesized from WO3-NiOCuO composite powder have been investigated. The metal oxide powder mixtures were prepared using a ball milling process. XRD analysis and HR-TEM revealed that the oxide powders are changed to W and CuNi alloy powders with an average particle size of about 100 nm by hydrogen reduction. To understand the reduction behavior of oxide powders, TG analysis was performed, and the reduction kinetics was evaluated by the amount of peak shift with heating rates. The activation energies for the reduction of WO3-NiO-CuO, estimated by the slope of the Kissinger plot, were measured as 60.6-114.4 kJ/mol depending on reduction steps.

Published: July 2024

Rapid Tooling able to produce complex prototypes directly from three-dimensional CAD software using materials such as polymer, wax, and paper, but it is typically used for low-volume production. The current technology uses epoxy filled with metal fillers such as aluminum or copper to enhance the mechanical properties of rapid tooling molds. This study aims to investigate the effect of using recycled brass filler mixed with epoxy resin as mold inserts for Rapid Tooling in injection molding applications. An optimal ratio of brass filler particles will be evaluated to determine the best physical and thermal properties for the mold inserts. Significantly, this study will encourage the use of recycled materials such as metal waste from machining to offer great help in environmental sustainability.
Effect of Annealing Temperature on Thermal Behaviour and Crystallinity of Zinc Oxide Supported Magnesium Aluminate (ZnO/MgAl2O4) Via Green Synthesis One Pot Fusion
Authors: Sukiman N.S. , Zavawi M.F. , Rahmat N. , Abdullah M.M. Al-Bakri
Published: July 2024

Zinc oxide-supported magnesium aluminate (ZnO/MgAl2O4) was synthesized by the one-pot fusion method, consuming magnesium nitrate, aluminum nitrate, and citric acid as starting precursors. The samples prepared were annealed at temperatures ranging from 700 to 900°C to study the influence of annealing temperature on thermal behaviour and crystalline properties. The thermal behaviour of ZnO/MgAl2O4 was characterized by thermogravimetric analysis (TGA), while the structural properties and crystalline phase of ZnO/MgAl2O4 were analysed by X-ray diffraction (XRD). The TGA results show that there were three stages of decomposition in the sample. The first stage indicates the removal of water content from the sample; the second stage indicates the decomposition of citric acid; and the third stage represents the crystallization phase formation at a temperature range of 800- 950°C. The percentage of citric acid decomposition increases with increasing annealing temperatures up to 800°C. However, the decomposition rate gradually reduces at annealing temperatures between 850 and 900°C. XRD analysis results suggest that microstructured ZnO/MgAl2O4 with high crystallinity can be obtained at the highest annealing temperature. It can be concluded that the result of thermal behaviour represented by the decomposition stage is corroborated with structural and crystalline properties at increasing annealing temperatures.
Effect of Post-Heat Treatment on the Mechanical Properties and Corrosion Behavior of Duplex Stainless Steel Fabricated by Wire Arc Additive Manufacturing
Authors: Zhang Long , Liu Liang , Liu Feihong , Sun Jian , Wang Dongsheng
Published: July 2024

In this study, the effect of heat treatment on the microstructure and mechanical properties of 2209 duplex stainless steel fabricated by wire arc additive was analyzed. It was found that solution treatment at 1100°C for 2 hours and tempering at 300°C for 2 hours can effectively improve the grain inhomogeneity of 2209 duplex stainless steel, eliminate γ2 and harmful brittle phases, and take into account the mechanical properties and corrosion resistance. Compared with the original deposition state, the hardness and yield strength increased by 10% and 31.8% to 245.6 HV and 499.7 MPa, which meet the requirements of engineering propellers. Electron back-scattered diffraction studies showed that the grains became refined and austenite maintained <101>//Z orientation after solution heat treatment. Many small-angle grain boundaries were present in both the original sample and the solid solution, but further tempering transformed the small-angle grain boundaries into large-angle grain boundaries.
The Effects of Heat Inputs on LDSS 2101 GTAW and SMAW Weld Microstructure and Mechanical Behavior
Authors: Sharma A. , Gudikandula S.
Published: July 2024

The welding has been utilized to stabilize the phase fractions in the microstructure of lean duplex stainless steel (LDSS) to build massive mechanical structures. The influence of heat input on the microstructure, mechanical properties, and corrosion behavior of LDSS 2101 during the gas tungsten arc welding (GTAW) and shielded metal arc welding (SMAW) processes is investigated in the present work. Specifically, we compared the outcomes between low heat input (LHI) at 0.85 kJ/mm and high heat input (HHI) at 1.3 kJ/mm for both welding techniques. Throughout the welding process, ER2209 filler wire was utilized. To assess the microstructural changes in the weldments, we employed an optical microscope, a scanning electron microscope, and X-ray diffraction. The results revealed that the volume phase fraction of ferrite was significantly higher in the LHI sample of GTAW compared to HHI GTAW and all SMAW welds. LHI GTAW welds have 18.2% greater Charpy impact toughness than LHI SMAW, whereas HHI GTAW has 35.7% higher than HHI SMAW specimens. The microhardness of the LHI GTAW weldments increased (from 230 ± 3.2 to 252 ± 4.8 HV10), whereas the microhardness of the LHI SMAW weldments increased (from 227 ± 2.8 to 246 ± 5.2 HV10). GTAW exhibited a fine grain structure, showcasing favorable tensile properties and higher hardness compared to SMAW. Conversely, the SMAW welds and their heat-affected regions exhibited coarse grain structures. These findings highlight the superior performance of GTAW in terms of microstructural characteristics, and mechanical properties when working with LD SS 2101 in comparison to SMAW.

Authors: Nabiałek J.
Published: July 2024

The paper shows the results of computer modeling of the polymer injection molding process. The influence of the gating system design on the warpage and volumetric shrinkage of the molded part was investigated. Particular attention was paid to the location of the gate. It has been proven that the selection of the place where the material is brought to the molding cavity has a significant impact on the final shape and quality of the molded part. The degree of compliance of its shape with the assumptions and dimensional accuracy was adopted as the criteria for assessing the quality of the molded part. The specialized software package Autodesk Moldflow Insight was used for numerical calculations. The obtained modeling results were related to the design recommendations of gating systems known from the literature.

Published: July 2024

Construction and demolition waste (CDW) management should focus on reducing CDW or properly recycling the materials since this waste is now a global problem. Sand brick waste, a component of a building’s structure, is one type of CDW. To be used as recycled aggregate, these wastes are invariably categorised as low grade. Due of the improved qualities provided, geopolymer research has recently become more popular. The objective of this study is to investigate the physical and mechanical properties of recycled sand brick aggregate (RSB) treated with silica fume based geopolymer coating. Additionally, the effectiveness of the treated RSB will be applied in concrete as coarse aggregate. The sample was made using a solid-to-liquid ratio of 1.0, 1.2, 1.4, 1.6, and 1.8. At 2.5 and 10 M, alkaline activator is a constant variable. Testing of specific gravity, water absorption, and aggregate impact value were analysed. The treated RSB concrete will then be evaluated against normal concrete. In terms of density, water absorption, and compressive strength, natural concrete performs better than treated RSB concrete. In comparison to natural concrete, treated RSB concrete absorbs 5.8% more water. Treated RSB concrete has a density of 1815 kg/m3, compared to natural concrete’s 2080 kg/m3. The compressive strength of concrete made using treated RSB aggregate is 18.1 MPa after 7 days, and 27.1 MPa at 28 days. The testing revealed that the treated RSB aggregate concrete met the specifications. As a result, treated RSB aggregate concrete offers an advantage over natural OPC concrete while saving the environment.
Socjologia i alienacja wiedzy
Authors: Giza Anna
Published: July 2024

W artykule podejmuję problem podwójnego zerwania więzi między uczestnikami życia społecznego a „społeczeństwem” jako przedmiotem badań socjologii. Uruchomiony w ten sposób proces narastania przepaści między potoczną samowiedzą społeczną a wiedzą naukową spełnia definicyjne cechy „alienacji”, rozumianej zgodnie z tradycją marksowską jako proces, w którym podmiot traci kontrolę nad wytworami swojej działalności i/lub elementami własnej podmiotowości, które jawią mu się jako zewnętrzne i obce. W artykule chcę argumentować na rzecz tezy, że alienacja wiedzy jest główną przyczyną coraz bardziej widocznego kryzysu społecznego, wyrażającego się spadkiem poparcia dla demokracji, wzrostem popularności partii prawicowych, ruchami antynaukowymi czy nasilaniem się populizmu.
Imaginaries of Care and Science in Anthropocene Utopian Futurology: The Sociology of Science in Kim S. Robinson’s The Ministry for the Future
Authors: Zaród Marcin
Published: July 2024

The article analyzes climate fiction utopia ‘Ministry for the Future’ by Kim S. Robinson. The analytical method relies on the framework of sociotechnical imaginaries proposed by Sheila Jasanoff and Sang-Hyun Kim and combines it with the critical history of science and feminist studies of care. Since in the process of writing the novel its author went through numerous consultations with scientists, in the article this oeuvre is analyzed both as a piece of science fiction and as a futurology essay. It is examined how the institutions of science are portrayed, how society of citizens is imagined and how this vision of the future remains trapped in the misconceptions regarding science that result from the Cold War modernistic propaganda of science. On the basis of this analysis, the article offers a discussion of how the imaginaries of Anthropocene are likely to repeat such tropes, unless history of science and sociology of science during the Cold War becomes a necessary part of the Anthropocene studies.
Redefining the Skills Required on the Labour Market in the Context of the Development of Artificial Intelligence Systems. Case Study on Finnish Universities
Authors: Călinescu Gabriela , Tanaşciuc Marcela
Published: July 2024

The rise of AI technology across different sectors has drastically influenced jobs and employment overall. This paper's goal is to identify and redefine the fundamental skills that are needed in the job market in relation to the massive application of artificial intelligence. The methodology used includes a case study and document analysis. The case study is centred on the Finnish universities that have implemented a project to connect academic training and professional requirements in the era of artificial intelligence. The results of this paper suggest a radical shift from the usual and well-known labour-oriented competencies to a far more complex cognitive and interdisciplinary array of skills like complex problem-solving, emotional intelligence, and flexibility. Most importantly, the case study that this paper brings forward underscores that the educational process and innovation must be sustained in the job market because technology can never be stagnant and is continuously redrawing the boundaries of the job's responsibilities. In a nutshell, the competencies required in the labour market will have to be recast with the integration and development of artificial intelligence systems. Such developments need proactive actions from stakeholders, especially educational institutions, through which a proper channel is established for the smooth coexistence of the workforce in the future headed by artificial intelligence.
Lean Supply Chain Management
Authors: Ionel Simona
Published: July 2024

In current competitive market, efficient supply chain management is essential to achieving sustainable business success. This paper explores the integration of lean principles into supply chain operations and its impact on enhancing the value creation stream. Lean principles, originally developed in the manufacturing sector, focus on waste reduction, continuous improvement, and value maximization from the customer perspective. By applying these principles to supply chain management, organizations can streamline processes, reduce costs, and improve overall efficiency. The study investigates key lean methodologies, such as Just-In-Time inventory, Total Quality Management and the 5S system, and examines their application in various stages of the supply chain, including procurement, production, and distribution. Through a combination of case studies and empirical data, the research highlights how lean initiatives lead to significant improvements in supply chain performance metrics, such as lead time, inventory levels, and defect rates. Findings demonstrate that lean supply chain practices foster a culture of continuous improvement and collaboration among supply chain partners, ultimately enhancing the responsiveness and agility of the supply chain. Furthermore, the paper discusses the challenges and best practices for implementing lean principles in supply chain management, providing a roadmap for organizations seeking to optimize their supply chain value creation.

Objetivo: exponer las características asociadas a los componentes del bienestar social de las familias de un ejido en la zona ixtlera en el semiárido noreste mexicano, identificadas a través del proyecto multidisciplinario que se lleva a cabo en este lugar, realizado con metodología de investigación acción participativa. Metodología: en esta fase inicial del proyecto, se comparten datos provistos por técnicas cuantitativas y cualitativas de alcance exploratorio y descriptivo, agrupados en los componentes del bienestar social doméstico: ingreso y educación, salud y alimentación, así como habitabilidad de la vivienda. Resultados: están limitados por la atención en los procesos de reproducción social doméstica en los hogares, dejando fuera el tema de las relaciones entre estos procesos y otras formas de reproducción política, económica y cultural de los sujetos. Limitaciones: hace falta una muestra más amplia para profundizar en la situación de los componentes del bienestar, y también analizar más el papel de los actores representantes de las instituciones de bienestar; trascender las limitaciones implica superar la fase exploratoria – descriptiva. Conclusiones: se resumen los hallazgos acerca de los componentes del bienestar social doméstico de las familias en este asentamiento y se resaltan los elementos que conforman la situación de pobreza hídrica en esta localidad, problemática articuladora de otras, la cual atraviesa las escalas ambiental, comunitaria y doméstica del proyecto.

Dignidade da pessoa humana e os alicerces morais fundamentais do intérprete
Authors: Canellas Guilherme da Silva Alfredo
Published: July 2024

A Dignidade Humana encontra proteção em normas jurídicas racionais e, simultaneamente, em valores morais que, em conjunto, atuam sobre a conduta das pessoas de forma cogente e intencional, respectivamente. Desta compreensão, pode-se afirmar não subsistir, teoricamente, espaço para a sua inobservância. Porém, não é o que se verifica na prática. Em toda parte a dignidade é lesionada por pessoas, grupos, empresas, instituições ou Estados Nacionais, estes últimos democráticos ou não e, independentemente da ideologia, liberais, progressistas, conservadores, libertários, totalitários e autocráticos de direita ou de esquerda. Este artigo tem como objetivo aprofundar a análise da dignidade humana a partir dos fundamentos morais do intérprete e oferecer uma nova compreensão do tema a fim de favorecer a proteção do ser humano.
Uma análise crítica dos direitos humanos: um produto cultural, a invenção de tradições e sua extensão aos animais
Authors: Coser Bitti Lohanna
Published: July 2024

O presente artigo visa explorar o tema direitos humanos sob uma perspectiva crítica, como sendo um fenômeno cultural, produto de invenção de tradições estabelecidas por povos dominantes. Essa visão não tradicional tem por finalidade compreender a realidade não romântica do nascimento de tais direitos, considerando suas raízes na exploração de uma classe dominante em determinado momento da história para então se perceber que não basta a previsão legal, é necessário também o reconhecimento de um novo paradigma, construído sobre um alicerce mais ético. A partir de então, examina-se a possibilidade de extensão dos direitos humanos a fim de incluir outros animais não humanos, tais como grandes símios e outros seres de capacidade cognitiva complexa. Essa ampliação dos direitos para além da esfera humana reflete uma evolução na compreensão ética e na busca por uma sociedade mais inclusiva e solidária, reconhecendo a interconexão entre os interesses humanos e a consideração ética pelos animais.

Virological and Serological Investigation of Feline Coronavirus Infection in Cats
Authors: Topçu Ahmet , Yıldırım Yakup
Published: July 2024

Feline coronavirus infection is an important viral disease affecting feline health. In this study, feline coronavirus infection (FCoV) in cats was investigated using virological and serological methods. For this purpose, both blood and stool samples were taken from 60 cats aged six months or older with or without clinical signs in different races, sexes, ages and social environments, which were not vaccinated against the aforementioned infection, which were kept as pets at home. Collected blood samples were checked for FCoV antibodies by applying FCoV rapid test-antibody (Ab) and indirect Enzyme Linked Immunosorbent Assay (ELISA) methods. Similarly, stool samples taken from the same cats were checked for the presence of FCoV antigen using the FCoV rapid test-antigen (Ag) method. Of the 60 cat blood serum samples analyzed, 21 (35%) were determined to be seropositive by rapid test-Ab method and 41 (68.33%) by indirect ELISA method. The difference between the antibody positivity rates determined as a result of the indirect ELISA method and the rapid test-Ab method was found to be statistically significant (P˂0.001). The presence of FCoV in 60 stool samples collected was investigated by rapid test-Ag method and 1 sample (1.67%) was found to be antigen positive. As a result of this research, the presence/prevalence of FCoV infection in owned cats was revealed both virologically and serologically. In addition, the indirect ELISA method was found to be more sensitive and reliable than the rapid test-Ab method in the serological diagnosis of FCoV infection.

Authors: Radifan Muhamad Almas , Hasanbasri Mubasysyir
Published: July 2024

Terdapat sejumlah remaja putri yang telah mengalami anemia di desa-desa sekitar wilayah kerja Puskesmas Mlati II, khususnya pada jenjang SMP yakni sebesar 21,03% dari total 233 siswi pada Januari 2020, yakni sebelum adanya pandemi COVID-19. Adapun prevalensi anemia remaja putri diperkirakan akan mengalami peningkatan pasca pandemi. Faktor utamanya adalah karena kebiasaan tidak sarapan, pola makan yang buruk, dan minimnya pelayanan kesehatan remaja. Faktor kemiskinan pada keluarga dan distribusi tablet tambah darah yang tidak teratur menjadi pendorong terjadinya masalah anemia remaja putri. Adapun dalam pencegahan masalah anemia remaja putri di desa-desa sekitar wilayah Puskesmas Mlati II, pihak PKPR dan nutrisionis Puskesmas Mlati II berencana untuk mendirikan posyandu remaja di tiap-tiap dusun. Harapannya, dalam inisiasi posyandu remaja nanti tidak hanya melaksanakan posyandu dengan lima meja saja, akan tetapi juga bisa mencakup program tambahan lainnya seperti webinar edukasi, online peer education, praktek sarapan bersama, dan praktek kebun gizi permaculture. Tujuan kegiatan ini adalah menciptakan posyandu remaja sebagai salah satu upaya pelayanan kesehatan remaja putri dalam mencegah anemia. Hasil dari kegiatan ini adalah berupa penjabaran urgensitas posyandu remaja bagi kesehatan remaja putri dan inisiasi posyandu remaja itu sendiri, seperti analisis situasi masalah anemia remaja, perencanaan rincian pelaksanaan program, termasuk pembentukkan kader remaja di dalamnya, serta penyusunan draft dokumen evaluasi.
