Authors: Ruiz Mazariegos Rubén Francisco , Loarca Pineda Alfonso
Published: November 2022

Los resultados de la investigación reflejan el estatus de la ganadería ovina en el área de estudio, actividad productiva que se enfoca como una cadena en formación, iniciando con el entorno agroecológico y los sistemas de crianza actuales, condicionados a las variables de uso de la tierra, cambio climático y vocación a la producción. Por tal razón se tomaron en cuenta 16 municipios considerados con la mayor cantidad de ovejas en el departamento. Para la captura de información de campo se utilizó un sistema automatizado de aplicaciones de respuesta rápida (ARR) e informática en la nube, que permite interactuar instantáneamente, llenando una base de datos en tiempo real y análisis de la información de forma gráfica para su interpretación, esta facilidad de proceso de datos permitió muestrear 599 sitios, los cuales están referenciados geográficamente, proporcionando además información fotográfica de los tipos de ovinos encontrados. La boleta electrónica en principio fue consensuada con un equipo especializado de personas, quienes la validaron a nivel de campo y posterior a realizar los ajustes correspondientes se inició la captura de datos en cada uno de los municipios seleccionados para el estudio. Cabe mencionar que durante la obtención de datos se contó con el apoyo de alcaldes, autoridades auxiliares y otros agentes de cambio de las comunidades intervenidas, permitiendo con ello que la información fuere confiable.
El impacto psicológico de la transición del ciclo diversificado del nivel medio a la Universidad en el estudiante
Authors: González Sosa de Rivero Dinora Nineth
Published: November 2022

La transición del ciclo diversificado del nivel medio a la enseñanza superior es un tema muy importante, porque puede ser un factor determinante en la estabilidad emocional del estudiante e influir directamente en la continuidad de sus estudios y en la calidad académica. Esta transición se establece desde el punto de vista psicológico a través de las reacciones emocionales que se producen en los y las estudiantes al pasar a través de este proceso. La concepción actual de la orientación educativa y universitaria determina que su función principal es la prevención y, por lo tanto, no tiene únicamente un carácter asistencial o terapéutico. La institución del ciclo diversificado del nivel medio juega un papel importante y determinante en la preparación psicopedagógica para esa transición que está a punto de concretarse en una realidad que debe superar en el primer ciclo universitario. La inmersión en la educación superior del estudiante es un periodo de transición primordial en su vida educativa y para su buena adaptación y éxito académico, por lo que, debe crear dinámicas interpersonales y emocionales que le permitan una buena integración, sin dejar a un lado el papel que la propia institución de enseñanza superior debe tener en la acogida de los nuevos estudiantes.

Desplazados ambientales: nuevos procesos de exclusión y desigualdad en Costa Rica
Authors: Centeno Morales Jacqueline
Published: November 2022

En esta investigación se buscó clarificar el impacto de los procesos socioambientales producidos por el cambio climático (entendido como el resultado de la interacción del ser humano con el medioambiente y su modificación producto de formas, modelos y modos de desarrollo productivo y económico de carácter invasivo, extractivo y explotador en los recursos) en las poblaciones costarricenses, de manera que comprometen su estabilidad en los territorios, forzándolas a desplazarse de manera temporal o permanente. Dicha relación se pretende visualizar a partir del estudio de eventos naturales desarrollados en Costa Rica en un periodo de 35 años (1980-2015) y su relación con factores económicos, sociales, naturales y culturales. El estudio de estos eventos conlleva a una temática poco estudiada en Costa Rica como lo es el desplazamiento ambiental entendido como “persona o grupos de personas que han sido forzadas u obligadas a huir de sus hogares o lugares a causa de un conflicto armado, de situaciones de violencia generalizada, de violaciones de los derechos humanos o desastres naturales o causados por el hombre, y que aún no han cruzado una frontera reconocida internacionalmente entre Estados o que lo hacen a fin de evitar los efectos de todo ello.” (ONU, 1998). Tomando en cuenta la conceptualización y el aumento de eventos naturales en el país, es pertinente el acercamiento a las percepciones, y experiencias de personas que hayan vivido los impactos de eventos naturales, por lo que este artículo presenta algunos casos del territorio costarricense como primeros acercamientos a la temática.

Mediante el proyecto de investigación “Puesta en Valor del Archivo Histórico de la Municipalidad de San Marcos, fase final”2 se ha desarrollado un proceso de identificación y descripción archivística con el propósito de construir un inventario documental, como un esfuerzo inicial para la sistematización del archivo local. El trabajo ha permitido localizar conjuntos documentales de gran valor para la historia en diferentes perspectivas. En lo que corresponde a Instrucción Pública del periodo 1855-1905 se han identificado 46 expedientes. La variedad de tipos documentales, desde libros de actas, cartas, bandos, oficios y decretos dan cuenta de los primeros esfuerzos por organizar e impulsar la Instrucción Pública a nivel nacional. El contenido de las fuentes resulta de gran interés para desarrollar nuevas líneas de investigación en la historia de la educación. El artículo que se presenta tiene como objetivo trazar una cronología de la Instrucción Pública en San Marcos entre 1855 y 1905 a través de la correspondencia localizada en el Archivo Histórico para comprender el desarrollo y cotidianidad de la educación en el municipio. Se concluye en el gran interés de los primeros liberales por difundir la instrucción primaria, sin embargo, el proyecto educativo se vio afectado por la escasez de fondos, la pobreza de las familias para enviar a los niños y niñas a las escuelas y la miserable condición de los preceptores en el ejercicio de sus funciones.
Sentimientos de autoeficacia docente a un año de la pandemia COVID-19
Authors: Azurdia Turcios Juan José
Published: November 2022

Los sentimientos de autoeficacia son las creencias y percepciones del docente respecto a sus propias habilidades de planificación, organización y ejecución de actividades diarias en la consecución de los objetivos educativos. Este estudio se propuso describir dichos sentimientos y asociarlos con otras variables. Con un enfoque cuantitativo, diseño de una sola medición y alcance asociativo, se aplicó la Escala de Sentimientos de Autoeficacia a 191 profesores del Departamento de San Marcos, Guatemala. Los resultados demuestran que no existe correlación entre el sexo, la edad y los sentimientos de autoeficacia. Por el contrario, si hay correlación positiva entre los años de docencia que han servido los profesores y los factores de la autoeficacia: eficacia percibida en el ajuste del estudiante (Rho= 0.01, p<0.05), eficacia en las estrategias de enseñanza y aprendizaje (Rho= 0.01, p<0.05), eficacia en el manejo de la clase (Rho= 0.001, p<0.05), eficacia en la atención a la singularidad de los estudiantes (Rho= 0.01, p<0.35), y el total de la escala (Rho= 0.00, p<0.05). Estos resultados pueden interpretarse al afirmar que a más de un año de educación en el contexto de la pandemia, los profesores de San Marcos han desarrollado una adaptación apropiada que les permite sentirse eficaces en sus capacidades para relacionarse con el estudiante, mantener la disciplina, implementar los métodos de enseñanza y aprendizaje y especialmente atender las necesidades individuales de los estudiantes.

Authors: Saputra Rudi , Ikhsan Jazaul , Prayuda Hakas
Published: November 2022

Sungai Progo merupakan sungai alami yang memiliki salah satu hulu yang bersumber di Gunung Merapi. Kondisi tersebut mengakibatkan Sungai Progo menerima dampak dari material yang terbawa oleh lahar dingin. Sedimentasi lahar dingin Gunung Merapi menghasilkan salah satu bahan bangunan yang memiliki nilai ekonomis tinggi yakni pasir. Hal tersebut menyebabkan terjadinya penambangan pasir di beberapa titik Sungai Progo. Penelitian ini bertujuan untuk menganalisis volume penambangan pasir, nilai ekonomis penambangan pasir, menghitung besaran angkutan sedimen, dan mengkaji dampak penambangan pasir terhadap stabilitas sungai progo (agradasi/ degradasi). Penelitian ini dilakukan untuk mengetahui data penambang pasir dan dampak ekonomi dari penambangan pasir, jumlah angkutan sedimen, dan nilai agradasi/degradasi Sungai Progo. Metode penelitian dilakukan dengan survei wawancara untuk mendapatkan data volume penambang pasir yang diambil setiap hari, kemudian angkutan sedimen dihitung dengan formula Englund dan Hansen (1950). Hasil penelitian menunjukan bahwa jumlah penambangan pasir sebesar 76680 m3/tahun, dampak ekonomi akibat penambangan pasir salah satunya adalah terbukanya lapangan kerja bagi masyarakat sekitar lokasi penambangan, nilai ekonomis yang dihasilkan oleh penambangan pasir per tahun senilai Rp. 6.129.000.000,- dengan jumlah penambang sekitar 198 orang, angkutan sedimen titik Jembatan Kebon Agung II sebesar 548.700,24 m3/tahun, titik Jembatan Kebon Agung I sebesar 485.977,69 m3/tahun, titik Jembatan Bantar sebesar 763.913,10 m3/tahun.

Published: November 2022

Aquaculture of the tropical sea cucumber Holothuria scabra or sandfish is still at a developing stage, especially in the Philippines. In Mindanao, early juveniles of sandfish were successfully produced at the Mindanao State University at Naawan (MSUN) sandfish hatchery for 5 yr now. However, on-site growing of these early juveniles in ocean nurseries often suffered very low survival rates. Two separate laboratory experiments were conducted for 60 d to test for the effects of feed types (Navicula sp., powdered Sargassum, and Sargassum extract) and salinity levels [ambient seawater at 32–35 (as control), 20, 25, and 40 ppt] on the growth, survival, and behavior of 7-wk-old early juvenile sandfish (2–15 mm in length). Juveniles fed with Sargassum extract significantly produced the highest increase in width and length, followed by powdered Sargassum and Navicula sp. with a survival rate of at least 71%. The highest growth rate (GR) and survival were observed with ambient salinity, followed by 40, 25, and 20 ppt. Unusual pale coloration, sluggish movement, and destroyed integument in some parts of the body were observed in some juveniles exposed to lower salinity indication of an unhealthy individual. Overall, Sargassum extract is an ideal feed for sea cucumber juveniles. Low salinity is stressful to early juvenile sandfish and that growth and behavior were adversely affected.

Published: November 2022

Herbal plants are often used as alternative medicine because they contain active compounds for the treatment of diseases and disorders with minimal side effects, and are easily obtained from the surrounding environment. Some of them have antiviral activity. This study aimed to analyze the potential of phytochemical compounds in the leaf of “pangi” (Pangium edule Reinw) as antiSARS-CoV-2 using molecular docking study. The drug- and lead-likeness properties of the selected compounds were obtained from the Swiss ADME and admetSAR online server tools. Molecular dynamics (MD) simulation of the selected ligand was carried out to validate the stability of the interaction. The results suggested that pangi leaves contain three compounds with remarkable binding affinities with Mpro (main protease) and RBD (receptor binding domain) were (5.beta.) pregnane-3,20.beta.-diol, 14.alpha.,18.alpha.-[4-methyl-3-oxo-(1-oxa-4-azabutane-1,4-diyl)]-, diacetate (PD), ethyl cholate (EC), and bis(3,5,5-trimethylhexyl) phthalate. Because EC will be metabolized in the body into cholic acid (Cho), this compound was then docked and validated using MD simulation. The compound has the best free binding energy (ΔG) with SARS-CoV-2 (–7.1 kcal/ mol with Mpro and –6.0 kcal/mol with RBD). Moreover, the compound is bound strongly to the active cavity of Mpro on Thr24, Thr26, His41, and Cys145 residues. The MM-GBSA calculation showed that the interaction of Cho with Mpro was higher than with RBD. According to the RMSD (root mean square deviation), RMSF (root mean square fluctuation), the radius of gyration (Rg), and intermolecular hydrogen bond (H-bond) analysis obtained from 50 ns MD simulations, Cho formed stable interactions with Mpro and RBD. The finding of this study indicated that Cho showed good anti-SARS-CoV-2 activity. The potential of the compound to inhibit the virus can serve as a starting point in the process of developing COVID-19 therapeutic natural medicine.

Coronavirus disease 2019 (COVID-19) continues to devastate the world’s health and economy, affecting all aspects of life leading to widespread social disruption. Even as several vaccines have been developed, their availability in developing countries is limited and their efficacy against the variants of SARS-CoV-2 (severe acute respiratory syndrome–coronavirus 2) needs to be continuously assessed. The World Health Organization (WHO) has acknowledged that vaccines alone will not overcome the global challenges of COVID-19. Medicinal plants may provide the needed support. Herein, we identify Philippine medicinal plants that possess phytochemicals with potential anti-SARS-CoV-2 activity and/or immunomodulatory properties that may strengthen one’s immune system against COVID-19. These plants were selected from 100 of the best-studied Philippine medicinal plants with antiviral and immunomodulatory properties. The general antiviral and specific anti-SARS-CoV-2 activities and immunomodulatory properties of the phytochemicals that these plants contained were searched. While many compounds assessed individually using in vitro and in silico techniques suggest potential anti-SARS-CoV-2 or immunomodulatory effects, this review sought to identify the medicinal plants which contain these compounds and which, based on literature, have the best potential application against COVID-19. These plants are Allium spp. bulbs (bawang), Andrographis paniculata (Burm.f.) Nees leaves (sinta), Cocos nucifera L. oil (niyog), Euphorbia hirta L. leaves (tawa-tawa), Euphorbia neriifolia L. leaves (sorosoro), Moringa oleifera Lam. leaves (malunggay), Ocimum basilicum L. leaves (balanoy), Piper nigrum L. seeds (paminta), Vitex negundo L. leaves (lagundi), and Zingiber officinale Roscoe rhizome (luya). This review provides a shortlist that can guide research on possible solutions to COVID-19 using Philippine medicinal plants.

Published: November 2022

Selecting a career track is crucial and must be thought of carefully because of its long-term impact on an individual’s future career. With the implementation of the K to 12 program in the Philippines, students need to choose from four career tracks before entering senior high school (SHS). Knowing the factors that may influence students’ career track choices can be helpful in the development of strategies that may help them make intelligent decisions. In this study, data from 3,813 Grade 11 students were analyzed to determine the variables associated with career track choice and the extent of influence of factors using descriptive, correlation, and correspondence analyses. Results showed that the intended course in college is strongly associated with SHS track/strand choice. Personal preference and parent’s influence are shown to be important factors. Socio-demographic variables such as sex, age, birth order, number of siblings, and monthly family income have a moderate association with the SHS track/strand choice. Likewise, parents’ highest educational attainment, the course taken in college, current occupation, and the student’s academic performance in several subjects (e.g. Filipino, English, Math, and Science) have a moderate linear relationship with SHS track/strand choice.
Development, Validation, and Application of a Three-way Cleanup Method for GC/MS Measurement of PCBs in Stranded Cetaceans in Philippine Waters
Authors: Bondoc Jonah , Aragones Lemnuel , Kwan Charita
Published: November 2022

Polychlorinated biphenyls (PCBs) are a group of synthetic organic chemicals that enrich the food chain via biomagnification where the highest levels have been detected in cetaceans. While several studies have reported cetaceans as sentinels of environmental pollution, information on the contamination status of PCBs in cetaceans found stranded along Philippine coasts has been very limited over the past decades. An important contributory factor to this paucity is the challenging analytical method for the analysis of PCBs in lipid-rich biological tissues due to lipid interferences that can affect gas chromatographic systems especially column efficiency and lifetime. Thus, a modified method consisting of a series of three cleanup steps – involving isolation column chromatography, gel permeation chromatography (GPC), and solid-phase extraction (SPE) using silica gel following Soxhlet extraction, plus macro- and micro-concentration prior to gas chromatographic/mass spectrometric analyses – was used. Recovery of added analytes corresponding to appropriate concentration ranges and repeatability of data values were excellent as values obtained were within the established performance criteria of 40–120% recovery, including a 106% mean recovery for the QC material (FAPAS T05100QC – Oily Fish) and < 30% RSD for an analyte concentration of 1 µg kg–1. Thus, the modified cleanup technique in conjunction with GC/MS detection is proven suitable for its intended use. Thirtyeight (38) congeners (PCBs-8, -12, -19, -18, -33, -38, -35, -37, -52, -44, -57, -74, -79, -78, -81, -77, -104, -99, -123, -118, -114, -126, -155, -153, -162, -167, -156, -157, -169, -188, -189, -202, -195, -194, -205, -208, -206, and -209) were detected in cetacean blubber (n = 15) ranging from 21.7 ng g–1 lipid weight (in an adult female dwarf sperm whale (Kogia sima) found in Camarines Sur) to 1460 ng g–1 lipid weight (in an adult male rough-toothed dolphin (Steno bredanensis) found in Zambales.
Kandelia candel (L.) Druce, a True Native Species in the Philippines
Authors: Malabrigo Pastor , Eduarte Gerald , Malabrigo Laarni , Coracero Ericson
Published: November 2022

Kandelia candel (L.) Druce is a true mangrove species under the family Rhizophoraceae. It is distributed throughout southeast Asia to south China, the Ryukyu Island and southern Japan, Taiwan, and Hong Kong. In the Philippines, its only known area of occurrence is the province of Aurora, the central easternmost coast of Luzon island. However, there has been a long-standing debate on the presence of natural populations of Kandelia candel in the Philippines. Adding to the confusion, a number of molecular studies reported that the Kandelia populations from north of the South China Sea (SCS) are a genetically different species – Kandelia obovata – making the genus non-monotypic. Some mangrove biologists hypothesized that Kandelia populations in Aurora might have been introduced to the province by some fishermen from Taiwan. On the other hand, some papers suggest that Kandelia populations in the Philippines were shaped by the founders from the populations in Southern SCS. A recent population inventory conducted by the authors, complemented by taxonomic characterization, strongly suggests that Kandelia candel is native in the province of Aurora, Philippines.

Published: November 2022

A SARS-CoV-2 lineage designated as Theta (P.3) with 16 signature mutations in the Spike protein region has been reported with cases centered in Region 7 of the Philippines. Whole-genome sequencing revealed that the 33 samples under this lineage all contain the E484K, N501Y, and P681H Spike mutations previously found in the SARS-CoV-2 variants of concern (VOCs): Alpha (B.1.1.7), Beta (B.1.351), and Gamma (P.1). This report focuses on possible implications of the mutations found in the Spike protein based on the analysis of the Theta variant’s structure, stability, and molecular surface character. The analyses included investigations using static models and molecular dynamic simulations between the Spike protein receptor-binding domain (RBD) and its interactions with the angiotensin-converting enzyme II (ACE2) receptor. Our results suggest that these mutations could significantly impact the possible interactions of the Spike protein with the ACE2 receptor and neutralizing antibodies, and warrants further clinical investigation. Some of the mutations affecting the N and C terminal domains suggest effects on Spike monomer and trimer stability. This report provides insights on relevant targets for the design of future diagnostics, therapeutics, and vaccines against the evolving SARS-CoV-2 variants within the Philippines.
Adsorption and Dissociation of H₂O₂ on Cu₂O(111) and F, N-doped Cu₂O(111) Surfaces for Potential Anti-microbial and Anti-pollutant Properties
Authors: Beronio Ellaine Rose , Santos-Putungan Alexandra , Putungan Darwin , Padama Allan Abraham
Published: November 2022

In this work, we probed the adsorption and dissociation of H2O2 on pristine plus nitrogen- and fluorine-doped Cu2O(111) surfaces via density functional theory to assess their efficacy as antimicrobial and anti-pollutant materials. It is found that H2O2 is chemisorbed on all surfaces with spontaneous dissociation into two OH species. Such dissociative adsorption is a result of charge transfer from the copper atom to H2O2, which activates the cleaving of the O-O bond. Further charge analysis revealed that charge transfer is most active in fluorine-doped Cu2O(111), which makes F- Cu2O(111) the most active surface in H2O2 adsorption and dissociation. Furthermore, this surface is found to promote the formation of H2O which could be of importance in other related reactions. Due to the weak interaction between fluorine and copper, it was observed that an extensive rearrangement of atoms occurred on the fluorine-doped Cu2O(111) upon H2O2 adsorption on the surface. This is in contrast to the nitrogen-doped surface, where the surface structure was maintained even after dissociative H2O2 adsorption. Our results point to the effective dissociation of H2O2 on doped Cu2O(111) and the efficient generation of reactive oxygen species (ROS), which are of significance in the degradation of bacteria, viruses, and organic pollutants.
Unsaturated Soil Hydraulic Conductivity (Kₕ) and Soil Resistance under Different Land Uses of a Small Upstream Watershed in Mt. Banahaw de Lucban, Philippines
Authors: Garcia Ronald , Galang Marco
Published: November 2022

Soil hydraulic conductivity influences hydrologic processes and the ability of watersheds to provide ecosystem services. Like most soil properties, however, it is highly spatially variable at different scales due to biophysical and anthropogenic factors. To quantify spatial variability, the study assessed the influence of land use/land cover (LULC) on soil hydraulic conductivity and compaction, as reflected by soil resistance in a small upstream watershed. Compaction was measured using a soil compaction tester and the unsaturated soil hydraulic conductivity (Kh) was estimated in the field using the inverse auger hole method. Measurements were made across six LULC: agriculture (Agri), coconut with agricultural crops (Coco + Agri), coconut with pasture (Coco + Grass), coconut with forest (Coco + Forest), reforestation area (Refo), and forest (Forest). Measurements were taken at 0–30 cm and 0–50 cm soil depths. Results showed that soil hydraulic conductivity and resistance significantly differed across LULC and soil depths. Soil resistance averages 0.83 MPa for all LULC at 0–30 cm depth, which was significantly lower (p = 1.184e–04) than 0–50 cm depth. Coco + forest recorded the highest soil resistance (1.01 MPa at 0–30 cm and 1.82 MPa at 0–50 cm), while Coco + Agri has the lowest resistance. Pairwise comparison of means also revealed that Forest at 0–30 cm depth had significantly higher (p < 0.01) Kh at 1.18 cm min–1 compared with other LULC across depths. Kh at 0–30 cm depth averages 0.57 cm min–1 for all LULC, which is significantly higher (p = 3.229e–02) than 0–50 cm depth. This indicated a decreasing hydraulic conductivity with increasing soil depth. This implies that strategies for promoting groundwater recharge and sustaining freshwater supply for lowland communities, in general, should be founded on LULC decisions, especially in upstream watersheds.

Published: November 2022

Epiphyas postvittana (Walker, 1863) is an invasive polyphagous pest for the Azores and its bioecology and the potential natural enemies were unknown. We evaluated the temporal profile of this species larval abundance and the number of males captured in sex pheromone traps, hypothesizing that both profiles were similar. The study was carried out on seven endemic host plants and one native species grown in two forest nurseries (Furnas and Nordeste) in São Miguel Island over two years from 2018 to 2019. A total of 827 plants attacked by E. postvittana were observed in Furnas nursery (2018: 503, 2019: 324) and 1227 in the Nordeste (2018: 649, 2019: 578), including the presence of 525 larvae distributed by the Furnas (2018: 178, 2019: 79) and from the Nordeste (2018: 131, 2019: 137). In 2019, the average weekly number of males captured in the sex pheromone traps (total 31 weeks) were higher in Furnas (mean ± SE: 9.68 ± 1.982) than in Nordeste (3.33 ± 0.651). In synthesis, (i) the population density varied throughout the year and as a function of the host plant species in production; (ii) the abundance profile of larval and adults suggests has at least three to four generations per year and that adults are active year-round, experiencing some delayed development during the winter; (iii) a low larval density does not represent very serious damage to Azorean endemic plants, but is reflected in the population density of its natural enemies; (iv) some biological control agents are present in the field, parasitizing the larvae (i.e., Braconidae species of Meteorus ictericus (Nees, 1811) and Microgaster opheltes Nixon, 1968); (v) finally, the knowledge of the population dynamics and its natural enemies needs further and long-term study.

As an important branch of applied anthropology, business anthropology has developed well in China in the recent past. This has attracted the attention of not only the academic society but also of industrial and commercial circles. This article illustrates the emergence and the development of business anthropology in China, and affirms the work of Chinese pioneers in this branch of cultural anthropology. It elaborates on what contemporary management and anthropological scholars have contributed to promote business anthropology in that country. Moreover, it expounds, from various perspectives, on the role that business anthropology can play for/in China. China is a large country developing at an astonishing speed. Chinese society is transforming from a traditional agricultural and pre-industrial phase into a post-industrial and commercial phase. Therefore, the development of business anthropology in China is promising.

Today's dynamic and highly volatile environment underlines the relevance of corporate entrepreneurship in all types of organizations to respond to current and forthcoming forces in a sustainable way. While extant research has identified several factors that impact corporate entrepreneurship, our understanding of how corporate entrepreneurship is impacted by strategic human resource management (SHRM) is underdeveloped. Drawing upon a dataset from 185 HR managers in Eastern Switzerland, Liechtenstein, and Western Austria, this study replicates the study of Wei et al. (2008) and examines the role of organizational culture in the SHRM adoption and implementation process and transfers their research design into the context of corporate entrepreneurship. The results indicate that SHRM impacts the implementation of organizational culture and that different HRM systems affect the implementation of different types of organizational culture.

Published: November 2022

In this study, we propose a way to link the scholarly contents of scientific papers by constructing a knowledge graph based on the semantic organization of argumentation units and relations in scientific papers. We carried out an argumentation graph data model aimed at linking multiple discourses, and also developed a semantic annotation platform for scientific papers and an argumentation graph visualization system. A construction experiment was performed using 12 articles. The final argumentation graph has 1,262 nodes and 1,628 edges, including 1,628 intra-article relations and 190 inter-article relations. Knowledge evolution representation, strategic reading, and automatic abstracting use cases are presented to demonstrate the application of the argumentation graph. In contrast to existing knowledge graphs used in academic fields, the argumentation graph better supports the organization and representation of scientific paper content and can be used as data infrastructure in scientific knowledge retrieval, reorganization, reasoning, and evolution. Moreover, it supports automatic abstract and strategic reading.
International perspectives on information avoidance during the coronavirus pandemic: Comparing media evaluations and media use in Pakistan, Germany, and Indonesia

This study investigates the comparative prevalence of information avoidance concerning the coronavirus and its relationship with media evaluation and use. We argue that information avoidance is a behavior that broadly signifies the intermittent and conscious practice of shunning specific content. It is problematic because having an informed citizenry is essential, especially during a global pandemic. Given the global affectedness of the world by the coronavirus, we believe in the necessity for international comparative research and conduct our study in Pakistan, Germany, and Indonesia. Based on the existing literature, which stems predominantly from the Global North, we assume that media use and its evaluations are associated with information avoidance and test our assumptions against cross-cultural differences. Hence, we collected data in Germany (n = 822), Indonesia (n = 1164), and Pakistan (n = 467). The results indicate important differences with regard to the prevalence of information avoidance as well as media use and its evaluations across the three countries. The analysis further confirms a rather stable relationship between media evaluations with information avoidance but revealed interesting differences in the associations between media use and avoidance.

Nowadays, we can observe the growing role of leadership not only in organizations, but also in hierarchical units. This importance is related to shaping the organizational culture of individuals and teams working in them. The aim of the article is to present the importance of leadership in shaping the security and organizational culture of hierarchical units on the example of the War Studies University. The analysis was made using Geert Hofstede's organizational culture model using participant observation. On the basis of the conducted analysis, it can be indicated that the discussed hierarchical unit is characterized by a high power distance, collectivism, masculinity, a high degree of avoidance of uncertainty and a short-term orientation in time. Such dimensions of organizational culture as: avoidance of uncertainty, collectivism and power distance have the greatest impact on the occurrence of a specific leadership style, and their verification should be an integral element of the exercised power in order to increase the level of structural security of the institution and personal security of members of this organization.

Trahison, hypocrisie et violence – la représentation de la masculinité musulmane dans Kiffe kiffe demain de Faïza Guène
Authors: Aronsson Mattias
Published: November 2022

Cet article porte sur la représentation de la masculinité dans Kiffe kiffe demain, le premier roman de Faïza Guène. La base théorique de l’étude est la branche des Gender Studies où l’on se concentre spécifiquement sur la construction de la masculinité (un domaine généralement appelé Men’s Studies ou Masculinity Studies en anglais).

La narratrice Doria et les autres personnages principaux de Kiffe kiffe demain habitent la banlieue parisienne et ils sont tous issus de l’immigration maghrébine. Par conséquent, nous nous intéressons plus particulièrement à la masculinité au sein de la communauté musulmane – telle qu’elle est décrite dans le roman.

 

Nous nous demandons si les personnages du sexe masculin sont porteurs d’une « masculinité islamiste » (au singulier) ou si on peut, au contraire, distinguer des identités masculines (au pluriel) plus complexes et hétérogènes. Notre étude indique que la masculinité islamiste est, en effet, très présente dans l’univers diégétique du roman, car la représentation de la communauté maghrébine y est assez problématique. Plusieurs personnages masculins de cette sous-culture sont même des caricatures d’hommes autoritaires et cruels.

Nous avons identifié trois aspects majeurs de la masculinité dans Kiffe kiffe demain : la trahison, l’hypocrisie et la violence – thèmes que nous jugeons intimement liés aux personnages masculins étudiés.
200 años de herencia lingüística afrolatina: descendientes de Ansina y otros soldados de Artigas en el Paraguay
Authors: Álvarez López Laura
Published: November 2022

Los datos lingüísticos analizados provienen en parte de comunidades afroparaguayas fundadas por los descendientes de esclavos libertos que fueron soldados de José Artigas, el "libertador y héroe nacional" del Uruguay. El objetivo del artículo es comparar los datos afroparaguayos analizados por Lipski (2009) con datos de variedades del español y portugués en contacto con lenguas africanas en Uruguay y Brasil para ver si coinciden o no. Con base en datos lingüísticos y socio-históricos, se argumenta que tal vez existan tantas o más similitudes con variedades de portugués afrobrasileño que con los datos sobre el habla de los afrouruguayos en los siglos XVIII y XIX. Esto puede explicarse a través de hechos históricos y sociales.
Los derroteros teóricos de una categoría heterogénea: los relatos de viajes al Nuevo Mundo (Siglo XVI)
Authors: Benites María Jesús
Published: November 2022

Este artículo se propone como un viaje que permite, a partir de un recorrido teórico, compartir mis avances e inquietudes sobre los alcances y limitaciones de la categoría “relato de viajes” sobre el Nuevo Mundo (Siglo XVI). Este recorrido concibe al relato de viaje como un género en cuya realización confluyen diversos criterios que hacen a su heterogeneidad. El relato de viajes, si bien pertenece a la familia de textos historiográficos, es el tipo discursivo en que se advierten mayores modulaciones.
