Published: October 2024

Optical logic gates based on nonlinear optical property of material with ultrafast response speed and excellent computational processing power can break the performance bottleneck of electronic transistors. As one of the layered 2D materials, Ta2NiS5 exhibits high anisotropic mobility, exotic electrical response, and intriguing optical properties. Due to the low-symmetrical crystal structures, it possesses in-plane anisotropic physical properties. The optical absorption information of Ta2NiS5 is investigated by anisotropic linear absorption spectra, femtosecond laser intensity scanning (I-scan), and non-degenerate pump-probe technology. The I-scan results show a distinct maximum of ∼4.9 % saturable absorption (SA) and ∼4 % reverse saturable absorption (RSA) at different polarization directions of the incident laser. And, these unique nonlinear optical (NLO) properties originate from the anisotropic optical transition probability. Furthermore, the novel Ta2NiS5-based all-optical logic gates are proposed by manipulating the NLO absorption processes. And, the all-optical OR and NOR logic gates possess an ultrafast response speed approaching 1.7 THz. Meanwhile, an all-optical information transmission method with higher security and accuracy is achieved, which has promising potential to avoid the disclosure of information. This work provides a new path for designing versatile and novel optical applications based on Ta2NiS5 materials.

Functionalized nanostructures and targeted delivery systems with a focus on plant-derived natural agents for COVID-19 therapy: A review and outlook
Authors: AbouAitah Khaled , Kim Beom Soo , Lojkowski Witold
Published: October 2024

The COVID-19 pandemic strongly stimulated research on anti-SARS-CoV-2 virus treatments. The present study reviews a nanotechnology approach to this task, i.e., in other terms, a nanomedicine approach. Nanotechnology aims to create nanostructures or nanoparticles, also called nanoformulations, for targeted delivery of drugs, as well as improved drug release control. This approach is particularly promising to enhance the antiviral effect of natural pro-drugs. Here, we review several nanoformulations developed for the targeted delivery of medications against SARS-CoV-2. We draw special attention to repurposing strategies for known antiviral and natural therapies. Also, functionalized nanoparticles with specific targeting moieties and functional groups were discussed. The summary could motivate researchers to pursue more studies in this exciting area by seeking nanotechnology-based, cutting-edge, tailored delivery strategies for the SARS-CoV-2 virus.

Wound healing is a critical process essential for the body’s recovery from injuries, often complicated by bacterial infections. Silver nanoparticles (AgNPs) have gained attention due to their antibacterial and tissue-regenerative properties. However, conventional chemical synthesis methods for AgNPs pose environmental risks. This study utilizes Ziziphus spina-christi (ZSC) extract for the eco-friendly synthesis of AgNPs, evaluating their antibacterial and wound-healing capabilities. The AgNPs-ZSC showed an absorption maximum at λ
max of 460 nm, a particle size of 111.2 ± 1.09 nm, a polydispersity index of 0.38 ± 0.006, and a zeta potential of −27.0 ± 0.231 mV. The synthesized AgNPs-ZSC were spherical, non-aggregated, and exhibited potent antibacterial activity superior to chloramphenicol. Furthermore, the AgNPs-ZSC cream significantly promoted wound closure, epithelial tissue proliferation, and granulation tissue formation in rats, showing no signs of toxicity or adverse reactions. In conclusion, AgNPs-ZSC cream demonstrates excellent antibacterial and wound-healing properties, presenting a sustainable alternative to conventional chemical methods for AgNP synthesis.

Published: October 2024

Presence of sacroiliitis (SI) is one of the hallmarks for diagnosing seronegative spondyloarthropathy, especially ankylosing spondylitis. In certain cases, the occurrence of erosions around sacroiliac joint due to other causes can mislead the diagnosis. We are discussing here a rare case of Ewing’s sarcoma, which clinically presented as SI.
Lupus erythematosus panniculitis presenting with initial periorbital swelling and positive antiphospholipid antibodies: A rare association
Authors: Oak Jyotsna , Rais Sama , Sawant Shankar
Published: October 2024

Lupus erythematosus panniculitis (LEP), an unusual form of chronic cutaneous lupus erythematosus, is characterized by chronic inflammation and fibrosis of subcutaneous tissue. Clinically, it presents as subcutaneous nodules on common locations such as forehead, cheeks, proximal limbs and buttocks. Ulceration of the nodules may occur in certain cases. Very few case studies have reported the occurrence of early solitary periorbital involvement, highlighting the need for a high index of suspicion in such cases. We report here a case having generalized extensive LEP with initial manifestation of a solitary periorbital swelling, autoimmune hemolytic anemia, and associated antiphospholipid antibodies positivity.
Human resource management in the armed forces: An investigation into the monetary incentive systems for military personnel
Authors: Lindgren Petter Y. , Presterud Ane Ofstad , Einarsdottir Iris Eva
Published: October 2024

How do the armed forces pay and compensate military personnel? In this article, this question is addressed by investigating the monetary incentive systems in place in the armed forces in twelve NATO and NATO-partner countries. The primary objective is to understand how the armed forces, in a variety of advanced countries, structure their compensation and personnel policies. The countries’ monetary incentive systems are analyzed and compared using a Request for Information distributed by the Norwegian Ministry of Defence to NATO and NATO-partner countries. The secondary objective is to motivate the research community in the nexus between personnel economics and defense economics to study monetary incentives in the armed forces in a cross-national perspective. There is great potential to learn from the experiences of compensation policies in other armed forces.
The effects of armed conflicts on local economic dynamics in the Mopti and Ségou regions of Mali
Authors: Tangara Mahamadou Bassirou
Published: October 2024

Armed conflicts significantly affect the social and economic conditions of societies in turmoil, disrupting the normal functioning of local economies. The study described in this article seeks to delve into the repercussions of armed conflicts on the dynamics of local economies in Ségou and Mopti, Mali, since the conflict outbreak in 2012. Employing a case study method, the research uses field observations and in-depth interviews with various stakeholders, including residents, displaced individuals, local authorities, former hostages, herders, farmers, traders, officials, and members of non-governmental organizations. The examination of the Ségou and Mopti cases underscores how armed conflicts have disrupted local production processes and curtailed population consumption patterns. Notably, weekly fairs that are pivotal for economic exchanges have been either prevented or abandoned by the populations. Additionally, farms face restrictions by enforced cultivation prohibition or the intentional burning of crops upon maturity. These findings contribute valuable insights into the nuanced effects of armed conflicts, cautioning against oversimplified generalizations derived from more aggregate analyses. The study sheds light on the intricacies of the local responses to conflict-induced economic challenges, offering a deeper understanding of the complexities involved.

Authors: Smith Ron
Published: October 2024

The recent growth in international tension has been associated with countries either increasing their military spending or discussing such increases—consequently, defense budgeting has attracted increased attention. This article reviews the U.K. defense budget in an historical context. It sets out the position in mid-2024 when the newly elected Labour Government commissioned a Strategic Defence Review. It summarizes the planning process and the government’s budget constraints; considers the issues involved in measuring the defense budget and making international comparisons; reviews trends in the defense budget; and the choices that need to be made between spending on personnel, conventional equipment, and nuclear weapons.
Convenio de Kioto Revisado: retos y oportunidades para Costa Rica
Authors: Rojas Noskova Kira
Published: October 2024

La facilitación del comercio es crucial para promover el intercambio de bienes y servicios en el mundo. Para lograrlo, los países participan de acuerdos y convenios multilaterales que permitan reducir los obstáculos en las transacciones comerciales sin detrimento de su capacidad para controlar y recaudar al tiempo que impulsa el crecimiento económico. Esto puede incluir mejoras esperadas en la facilitación del comercio, menores costos de transacción, mayor eficiencia en los procedimientos aduaneros y mayor competitividad en el comercio internacional. Sin embargo, la implementación de normativas que regulan el tema no está exenta de desafíos. En presente artículo investiga las reservas hechas por partes contratantes del Convenio de Kioto Revisado, así como las interpuestas por Costa Rica en el proyecto de ley enviado a votación en el plenario legislativo, para conocer el verdadero alcance de la implementación de este Convenio, los beneficios y los retos previstos al adoptarlo. El enfoque metodológico consiste en el análisis de la coyuntura de Costa Rica respecto a la facilitación del comercio en el marco legal multilateral. Mediante la revisión detallada de documentos e instrumentos legales, se identificaron los temas que más resistencia causan entre los países como la declaración de mercancías. También, se determinó la naturaleza de las reservas planteadas por Costa Rica y se comprendió como se engrana este Convenio en la estrategia nacional de facilitación del comercio. Asimismo, se identificaron los beneficios de implementar el Convenio de Kioto Revisado para sectores como transportistas internacionales, importadores, exportadores y gobierno. Finalmente se comenta que el país enfrenta retos relacionados con la coordinación transfronteriza, desarrollo de capacidades técnicas, capacitación de funcionarios aduaneros, seguridad aduanera, entre otros.
Range extension and new records of two Oxyuroidea Cobbold, 1864 parasitizing Cliff Chipmunk, Neotamias dorsalis (Baird, 1855), in the Área de Protección de Flora y Fauna Cerro del Mohinora, Chihuahua, México

As part of an inventory of the parasitic helminths of rodents, two species of the class Oxyuroidea (Heteroxynema cucullatum Hall, 1916 and Rauschtineria eutamii (Tiner, 1948) Hugot, 1980) were collected from three Cliff Chipmunk specimens (Neotamias dorsalis (Baird, 1955)) in the Área de Protección de Flora y Fauna Cerro del Mohinora, Mexico. These nematodes have been recorded in different species of the genus Neotamias (Illiger, 1811), which can be found in sympatry mainly along the entire west coast of the USA. This is the ﬁrst record of both species in Mexico.

Concurrent infections with two or more pathogens with analogous tropism, such as RSV and SARS-CoV-2, may antagonize or facilitate each other, modulating disease outcome. Clinically, discrepancies in the severity of symptoms have been reported in children with RSV/SARS-CoV-2 co-infection. Herein, we propose an in vitro co-infection model to assess how RSV/SARS-CoV-2 co-infection alters cellular homeostasis. To this end, A549-hACE2 expressing cells were either infected with RSV or SARS-CoV-2 alone or co-infected with both viruses. Viral replication was assessed at 72 hours post infection by droplet digital PCR, immunofluorescence, and transmission electron microscopy. Anti-viral/receptor/autophagy gene expression was evaluated by RT-qPCR and confirmed by secretome analyses and intracellular protein production. RSV/SARS-CoV-2 co-infection in A549-hACE2 cells was characterized by: 1) an increase in the replication rate of RSV compared to single infection; 2) an increase in one of the RSV host receptors, ICAM1; 3) an upregulation in the expression/secretion of pro-inflammatory genes; 4) a rise in the number and length of cellular conduits; and 5) augmented autophagosomes formation and/or alteration of the autophagy pathway. These findings suggest that RSV/SARS-CoV-2 co-infection model displays a unique and specific viral and molecular fingerprint and shed light on the viral dynamics during viral infection pathogenesis. This in vitro co-infection model may represent a potential attractive cost-effective approach to mimic both viral dynamics and host cellular responses, providing in future readily measurable targets predictive of co-infection progression.
Differences in codeswitching patterns between immigrant and heritage speakers of US American Danish
Authors: Kühl Karoline , Heegård Petersen Jan
Published: October 2024

This paper addresses intrasentential code-switching in US American Danish spoken by 1st generation immigrants from Denmark, who migrated to the US around 1900 as part as the transatlantic European mass emigration and their descendants (2nd and 3rd generation). The analysis is based on the Corpus of American Danish, specifically a dataset of 173 speakers producing 46 hours of speech. In this dataset, we observe significantly different patterns of intrasentential code-switching in the speech of the immigrant speakers (1st generation) and US-born heritage speakers (2nd and 3rd generation): The code-switching patterns of the heritage speakers show a preference for English lexemes that are integrated morphologically into Danish or which are part of Danish-English bilingual compounds. In contrast, the immigrant speakers prefer non-integrated English words for code-switching. This result taken per se shows that code-switching patterns show variation across generations just as other linguistic variables. Taking the result further, we have connected it to a previous study of representations of linguistic proficiency in immigrant Danish in the Americas. By this, we are able to show that the morphologically or lexically integrated code-switching of the heritage speakers correlate with features representing fluent speech, while the non-integrated code-switching of the immigrant speakers rather seems to correlate with features showing a low activation of Danish in a situation of language shift. Thus, the heritage speakers seem to have developed a way of speaking US American Danish where English word stems are an integrated part of speaking fluently and lexically varied.
Toronto Heritage Italian (r): Maintaining homeland patterns
Authors: Cristiano Angela , Nagy Naomi
Published: October 2024

Contrary to experimental research, comparative variationist approaches find for heritage speakers many cases of maintenance of the homeland grammar. We analyze patterns of rhotic production in spontaneous speech of the heritage Calabrese Italian community of Toronto, Canada, and its homeland counterpart in Calabria, Italy. 1,555 tokens of word-internal, singleton /r/ were collected from the HLVC corpus and analyzed using mixed-effects models. Results show an ongoing pattern of lenition for both homeland and heritage speakers. Heritage speakers further develop this language internal trend, indicating grammar boosting. Homeland social constraints are maintained by heritage speakers. We find no evidence of transfer from English or simplification in the heritage language. Similar patterns of rhotic lenition are found in heritage Tagalog (Umbal & Nagy 2021) and Russian (Nagy 2024), though with different social constraints. Cross-linguistic comparison proves that variation in heritage languages is not necessarily caused by contact, and that change needn’t be related to indexicality.
Intellectual and Political Sociability Between the Late ECLAC and CIEPLAN: From Criticism of the Chilean Economic Model (1973-1990) to the Birth of Neo-Structuralism
Authors: Resende Marcos Taroco
Published: October 2024

The paradigmatic rise of the Chicago Boys during the Pinochet regime (1973-1990) was a radical response against the state-led import substitution industrialization and its intellectual influence from CEPAL. Although CEPAL's ideas and history have attracted great interest, reflections on CEPAL’s role during the Chilean authoritarian regime are often limited. In this paper, I intend to offer systematic new evidence and perspectives on the behavior of CEPAL during Pinochet’s government. I argue that, in a context where CEPAL had been losing its influence and experimenting with several problems, some of its economists developed political and intellectual sociability with members of the think tank called Corporation of Studies for Latin America (CIEPLAN) to criticize Chilean economic policies. Moreover, this complex historical process was one of the sources of the birth of neo-structuralism in the late 1980s.
Articulación de las Tecnologías de la información y comunicación en la Formación profesional colombiana: Un análisis de los Programas de Pregrado en Psicología
Authors: Torres Reyes Aura María , Castellanos Vega Reina Lucila , Villa Valencia Alberto
Published: October 2024

La psicología, como disciplina, hasta hace unos años no requería el desarrollo de competencias digitales. Sin embargo, a medida que las Tecnologías de la Información y Comunicación (TIC) aumentan su incursión en los medios productivos se incrementa la necesidad de desarrollar habilidades tecnológicas para mejorar la articulación con el escenario laboral y las demandas del mercado. Por tanto, este estudio se propuso describir la articulación de las TIC dentro de la formación profesional de psicología en Colombia. Para lograrlo se diseñó un estudio descriptivo de enfoque mixto con cuatro momentos de observación que incluyeron la totalidad de programas académicos activos que conducen a la obtención del título profesional en psicología (n=134). Como resultado general se observa una integración alta de las TIC en procesos administrativos, específicamente en la digitalización del proceso de admisión, y moderada en lo que respecta a la articulación dentro de los programas de psicología lo cual se corresponde con el contexto laboral inmediato, esta articulación tiende hacia el desarrollo de competencias de uso, siendo poco representativas las competencias tecnológicas disciplinares o de creación. Está orientación en los procesos de desarrollo de competencias digitales podría limitar el impacto transformacional de las TIC y el acceso a las ganancias derivadas del sector tecnológico para los profesionales de psicología con todas sus implicaciones. Recomendamos estudios posteriores que aborden la temática de la formación y el ejercicio profesional de la psicología con relación a la articulación de tecnologías de la información y comunicación.
Economic policy and public health: Insights from the history of the Canadian Journal of Public Health
Authors: McLaren Lindsay , Mykhalovskiy Eric
Published: October 2024

The nearly 115-year history of the Canadian Journal of Public Health (CJPH) provides an important opportunity to reflect on and learn from our past. In response to an invitation to members of the CJPH Editorial Board to curate historical articles around a theme, we undertook a historical examination of our field’s engagement, as gleaned through the pages of CJPH, with economic policy. This was inspired by the now well-established connections among political economic policy, population well-being, and health equity. Our analysis of six historical volumes (1917, 1933, 1941, 1961, 1995, and 2013) led to three key findings. First, we found only a slim historical foundation for public health engagement with the economy overall. Second, we observed a strong and seemingly subconscious allegiance to dominant economic paradigms, despite their incompatibility with root causes of health inequities. Third, even though socio-economic inequalities in health are a long-standing preoccupation of CJPH authors, those inequalities are consistently and curiously divorced from their roots in political economic systems. Our findings provide a historical foundation for thinking about how our public health community could be encouraged to engage constructively towards an economic system that supports, rather than obstructs, population well-being and health equity.
Understanding right-wing populists’ anti-abortion politics in Turkey: The symbolic violence of the state
Authors: Kutun Melehat
Published: October 2024

This study investigates how symbolic violence is shaping anti-abortion stances associated with legitimising right-wing populist policies. The prominent questions are as follows: What are the institutional and politico-administrative mechanisms that are impacting anti-abortion politics in terms of material and symbolic violence? How and to what extent does anti-abortion politics influence the interplay between symbolic and material state violence? The study argues that reproduction-centred policies and material and symbolic violence have intensified through anti-abortion politics in the discursive context of the social reproduction crisis in Turkey. It explores the institutional actions and the legitimation mechanisms of anti-abortion policies in relation to the penetration of right-wing populist politics after the authoritarian turn of 2010. This qualitative case study uses critical discourse analysis. It interprets the public speeches of representatives of the government and documentary data concerning the ruling party’s programmes, development plans and relevant legislation. The research provides a gendered perspective on the anti-abortion policies that anchor right-wing populism in terms of the crisis of social reproduction. It also contributes to critical state theory and pre-existing feminist scholarship on right-wing populism.
‘Sympathy for the devil’: The strategic use of the populist repertoire in Viktor Orbán’s politics
Authors: Metz Rudolf
Published: October 2024

Populist politicians such as Viktor Orbán are masters at harnessing intense and polarizing moral emotions: they stigmatize the enemies of the people, offer their community protection as self-proclaimed heroes, and at the same time, othering and moral transgressing trigger emotional overreactions from opponents. This article draws on a new analytical framework that incorporates theories of social labeling (moral panic and euphoria, moral entrepreneurship) and heroic/charismatic leadership to explore this multifaceted and antagonistic emotional relationship associated with populists. The theoretical reasoning suggests that these emotional dynamics define the moral cornerstones and boundaries of populist identity politics. Based on an analysis of four illustrative Hungarian cases – the migration crisis, anti-gender politics, the Authorisation Act during the coronavirus pandemic, and Fidesz’s expulsion from the European People’s Party – the article shows that populists can follow different paths to become charismatic heroes in the eyes of his supporters, while others still see them as folk devils due to their controversial moral entrepreneurship.
From neighbour to member: Assessing Moldova’s EU membership perspectives
Authors: Longhurst Kerry
Published: October 2024

This article examines Moldova’s prospective membership in the European Union (EU) in the wake of the EU’s renewed enlargement drive which was prompted by Russia’s 2022 invasion of Ukraine. It explores the dynamics shaping Moldova’s accession path, spotlighting obstacles to integration that official reports appear to overlook or underplay. The article compares EU and Moldovan documents, civil society reports, and insights from interviews with Moldovan officials and civil society representatives to gain a nuanced picture of the evolving situation. Attention is also given to the distinct characteristics of the currently unfolding enlargement process, including its sense of urgency and geopolitical significance which have led to calls for an expedited or ‘fast-track’ accession. Findings note that despite Moldova’s impressive progress in aligning with EU standards in many areas, substantial hurdles in justice reform, combating corruption and de-oligarchisation persist. Incomplete public administration reforms, uneven civil society involvement in decision-making, and issues associated with the Transnistria conflict also have consequences for Moldova’s EU prospects, especially if an expedited version of enlargement occurs.

PUBLIC DIPLOMACY OF UKRAINE UNDER MARTIAL LAW
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Pipchenko N. , Darnytskyi A. ,   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine
Published: October 2024

The article describes the political-diplomatic, economic-investment, cultural-artistic and educational, as well as public and media instruments used by the state and civic institutions of Ukraine in public diplomacy during 2022-2023. It was established that the instruments made it possible to ensure the refutation of false information about Ukraine and relevant events, as well as encourage the unification of international efforts to provide comprehensive assistance to the state and its citizens. The strengthening of the economic, cultural, and educational component of foreign policy activity, which will be implemented both under the ongoing state of war and post-war peacebuilding, can become promising directions of Ukraine’s public diplomacy. At the same time, Ukraine’s trauma-informed public diplomacy will focus on disseminating information about the nation’s achievements and spiritual values, restoring cultural stability, overcoming existential anxieties, and providing assistance to other countries.
ESTABLISHING AND CONTROLLING A STABLE MORAL AND PSYCHOLOGICALCLIMATE IN FOREIGN DIPLOMATIC INSTITUTIONS AS A KEY SECURITYCOMPONENT
Authors:   Yevhenii Berezniak Military Academy, Kyiv, Ukraine, Balitskyi Viacheslav , Loban Olena ,   Yevhenii Berezniak Military Academy, Kyiv, Ukraine
Published: October 2024

This article addresses the issues of forming and controlling a stable moral and psychological atmosphere in the foreign diplomatic institutions (FDI) of Ukraine, as well as preventing and localizing potential negative markers in FDI and their impact on security. The role of management and security officers (FDI SO) is emphasized. Modern negative global trends such as increased competition for natural resources, sustained tension in certain states and regions, acceleration of the arms race, manifestations of terrorism, organized crime, smuggling, drug and arms trafficking, illegal migration, human trafficking, the threat of escalation of frozen conflicts, and the emergence of new sources of international tension, including the undeclared aggressive hybrid war by the russian Federation against Ukraine and the activation of its intelligence services, impose on Ukraine's special bodies the task of most effectively ensuring the national security of the state, including the security of Ukrainian foreign diplomatic institutions, their staff, and family members, as well as Ukrainian state secret holders sent abroad. The comprehensive nature of addressing security issues in FDI, especially the potential impact of negative signs within diplomatic teams on their security, necessitates thorough scientific analysis. The results of such work will serve as a foundation for further improvement of state political and legal acts, departmental orders, instructions, and relevant practical recommendations for leadership and FDI SO for the proper fulfilment of their duties.
Historical Traditions and Values as Foundation of the Russian Legal System
Authors: Grishina T. M.
Published: October 2024

The amendments in 2020 to the Constitution of the Russian Federation of 1993 were a decisive step towards strengthening sovereignty in the international arena and the reception in the Russian Federation of historical traditions and value attitudes characteristic of Russia in any historical form of its statehood. The unity of state ideology, which is directly prohibited in the chapter «Fundamentals of the Constitutional System» of the Basic Law of Russia, has become the subject of special attention of the developers of the text of constitutional novels due to the impossibility of amending chapters 1, 2 and 9. Additions and changes made to chapters 3‑8 positively influenced and significantly softened Art. 13 (part 3), but did not completely eliminate the problems and contradictions between constitutional norms and the objective need to restore the ideological sphere in the Russian state, before the growing aggressive expansion of alien values imposed by a number of unfriendly countries. The discourse taking place in the scientific community and at all levels of public power in the state on the issue of the invariability of chapters 1, 2 and 9 of the Constitution of the Russian Federation leads to the idea of the advisability of revising the current constitutional act in the future. At the present stage, positive prospects are noted in solving ideological, socio-economic, geopolitical and other problems, as well as developing an effective strategy in the field of national security of the Russian Federation, which is greatly facilitated by the updated and improved Constitution of the Russian Federation in 2020.
Organizational and Legal Grounds for the Activities of the Prikaz System of Central Government in Russia (Late 15th — First Half of the 16th Century)
Authors: Shauro I. G. , Plekhanova M. A.
Published: October 2024

The paper presents an author’s analysis of the organizational and legal basis of the prikaz system that was formed in the Russian state at the end of the 15th — first half of the 16th centuries. In the period under review, the previously existing palace and patrimonial system of organs, aimed at solving the applied tasks of ensuring the management of the princely court, but assuming the presence of boyar estates, could no longer effectively respond to the challenges the state faced. There was a need for centralized state control and management bodies. Prikazes were such bodies. At the same time, the level of development of law made it possible to give both the prikaz system itself and its functioning normative features. The sources of that time not only mention certain bodies and positions, but also establish the foundations of their legal status: a place in the system of government and administration, rights, obligations, responsibility. Of course, such a consolidation, that was fundamentally different from the previous approach to this issue, at the end of the 15th — the first half of the 16th century was not systemic and comprehensive. At the same time, it is obvious that it had already taken shape. The authors considered the signs of the origin of legal regulation of both the organizational structure of prikazes and the procedure for their functioning. According to the results of the study, it is concluded that at the end of the 15th — the first half of the 16th century organizational and legal foundations of the prikaz system of the Russian state had already begun to form on the basis of key regulations of that time — the Judicial Code of 1497 and the Judicial Code of 1550. Acting under the control of the sovereign, the prikaz system acted as the core in the management of the united state. The fundamentals of the functioning of orders laid down by the legislator provided effective leadership and a systematic approach to solving domestic problems.

Em parte do território brasileiro os fatores climáticos podem limitar o plantio de milho tardio, porém, no Pará, esta estratégia apresenta condições de contribuir para a redução da pressão sobre a floresta, principalmente quando a adubação nitrogenada é empregada, possibilitando rendimentos acima da média nacional. Neste sentido, com o objetivo de avaliar a influência de doses de nitrogênio aplicadas em híbridos de milho semeados de forma tardia, este ensaio foi conduzido em um esquema fatorial 2 x 4 com dois milhos (K9606 e 30F35) e quatro doses de nitrogênio (0, 50, 100 e 200 kg ha-1). O número de folhas verdes e total, apresentou diferença para os milhos, sendo maiores no híbrido 30F35. A altura de plantas, diâmetro do colmo e comprimento de folhas responderam com um ajuste quadrático ao nitrogênio com doses próximas de 150 kg ha-1. A produção de grãos, o comprimento e o diâmetro da espiga ajustaram-se de forma linear crescente à fertilização com ureia, sem diferença entre os híbridos, demonstrando potencial de resposta para doses superiores a 200 kg ha-1 de nitrogênio. A adubação nitrogenada diminuiu a eficiência agronômica e a produtividade parcial do fator N.

Abstract
In part of the Brazilian territory, climatic factors can limit the planting of late corn, however, in Pará, this strategy is able to contribute to reducing pressure on the forest, especially when nitrogen fertilization is used, enabling yields above the national average. In this sense, with the objective of evaluating the influence of nitrogen doses applied to corn hybrids sown late, this trial was conducted in a 2 x 4 factorial scheme with two corns (K9606 and 30F35) and four nitrogen doses (0, 50, 100 and 200 kg ha-1). The number of green and total leaves showed a difference for corn, being higher in the 30F35 hybrid. Plant height, stem diameter and leaf length responded with a quadratic adjustment to nitrogen with doses close to 150 kg ha-1. Grain production, ear length and diameter adjusted in a linearly increasing manner to urea fertilization, with no difference between hybrids, demonstrating potential response to doses greater than 200 kg ha-1 of nitrogen. Nitrogen fertilization decreased agronomic efficiency and partial productivity of the N factor.

The Publicizing of the Femicides of Searching Mothers in Mexico
Authors: Zavaleta Betancourt José Alfredo
Published: October 2024

This article analyzes the publicizing of the femicides of searching mothers from the perspective of sociology of critique. To this end, it tests an actantial model of complaints through a digital ethnography based on public texts, with the purpose of understanding the slow process of configuration of this social problem as a public problem. The work analyzes this type of feminicide, whose execution pattern is related to the field of organized violence, through a strategy focused on the justifications of the actors involved. In this logic, it reconstructs the stories and narratives of the political and social actors involved in the process, describes relationships between experts and victims in the complaint and access to justice, and provides elements for understanding the meaning that social and political actors give to their experiences of this borderline social problem. The article closes with some considerations about the challenges in researching the structural effects of this type of violence in the field of social sciences and multi-localized public action at a national and subnational scale.
The Pacific Alliance. More Cooperation Than Integration
Authors: Ardila Martha
Published: October 2024

The Pacific Alliance was established as a strategy of open regionalism in the region that seeks closer ties with Asia-Pacific and greater interdependence among its members. However, 13 years after the signing of the agreement, the results are more cooperation than integration. The changing Latin American political landscape shows a weakening of this multilateral organization, giving way to regionalism and a soft and pendular leadership. This article mentions its stages, achievements and future possibilities. Its evolution and trajectory have not been homogeneous, but rather present ups and downs and the possibility of new issues. The methodology is qualitative, combining primary and secondary sources, and counterbalances media with academic analysis.

Fear of Missing Out (FOMO): Exploring Its Relationship with Self-Control and Self-Regulation in College Students
Authors: Amelisastri Windy , Yandri Hengki , Kholidin Farid Imam
Published: October 2024

This study investigates the potential influence of self-control and self-regulation on Fear of Missing Out (FoMO) among students.  FoMO is characterized by an apprehension of being excluded from significant experiences or opportunities.  Individuals with low self-control may struggle to prioritize positive behaviors, potentially leading to heightened FoMO.  Similarly, a lack of self-regulation, the ability to manage thoughts and guide actions towards goals, might exacerbate FoMO. The current research employs a quantitative, descriptive correlational design.  The study population comprised 2,245 students from the Faculty of Tarbiyah and Teacher Training at Institut Agama Islam Negeri Kerinci.  A sample of 304 participants, representing 10 departments, was selected.  Data collection utilized three validated scales: the Self-Control Scale, the Self-Regulation Questionnaire, and the Fear of Missing Out Scale. The hypothesis proposing a significant negative association between self-control/self-regulation and FoMO was supported (p < 0.05).  This suggests that both self-control and self-regulation have a combined effect on FoMO.  In simpler terms, individuals with greater self-control and self-regulation may experience lower levels of FoMO. Future research could explore specific factors contributing to FoMO development. Additionally, expanding the sample size might enhance the generalizability of findings.

Authors: Muhtadi Hasna Fathinah , Ahman Ahman
Published: October 2024

Grief due to the loss of a loved one is a normal reaction that can be experienced by teenagers, but if it interferes with daily life and lasts for a long time, this condition can develop into a prolonged grief disorder. The PG-13-R instrument was introduced by Holly Prigerson, designed to measure prolonged grief disorder. Research is needed to confirm the psychometric performance of the PG-13-R in samples with broader ethnicities. This research involved 242 students at SMKN 1 Tasikmalaya, Indonesia using a descriptive quantitative approach. This research aims to measure and describe the characteristics of the validity and reliability of the Indonesian version of the PG-13-R instrument for adolescents who have experienced loss. The results of the validity and reliability test show that the Indonesian version of the PG-13-R instrument has a good level of validity and reliability, with all items declared valid and a high reliability value (Cronbach's alpha = 0.888). Thus, the adapted PG-13-R instrument can be indicated as a valid and reliable measuring tool for identifying prolonged grief disorders in adolescents in Indonesia.

Una aproximación al despido colectivo como medida de reestructuración empresarial tras las últimas reformas laborales
Authors:   Universidad Autónoma de Barcelona, Gala Durán Carolina
Published: October 2024

Uno de los objetivos esenciales de las reformas laborales que se han aprobado en los últimos años ha sido ampliar el alcance de las medidas de reestructuración empresarial, destinadas a facilitar que una empresa, ante una situación de crisis, pueda adaptar las condiciones de trabajo de sus trabajadores. Medidas que, por otra parte, presentan un alcance diverso y que permiten tanto la modificación de las condiciones laborales (funciones, salario, jornada…), como la suspensión temporal de los contratos o el despido de los trabajadores. El objetivo de este trabajo es analizar, con cierto detalle, una de las vías de reestructuración empresarial más conocidas en la práctica empresarial, que se ha visto facilitada en los últimos años y que comporta graves consecuencias para los trabajadores afectados: el despido colectivo o expediente de regulación de empleo. De este modo, se analizan los importantes cambios introducidos en este ámbito, especialmente por la reforma laboral de 2012, tanto desde la perspectiva sustantiva como procedimental, así como los criterios judiciales que están interpretando (y reinterpretando) el vigente marco legal.
