Utility in Time Description in Priority Best–Worst Discrete Choice Models: An Empirical Evaluation Using Flynn’s Data
Authors: Adikari Sasanka , Diawara Norou
Published: February 2024

Discrete choice models (DCMs) are applied in many fields and in the statistical modelling of consumer behavior. This paper focuses on a form of choice experiment, best–worst scaling in discrete choice experiments (DCEs), and the transition probability of a choice of a consumer over time. The analysis was conducted by using simulated data (choice pairs) based on data from Flynn’s (2007) ‘Quality of Life Experiment’. Most of the traditional approaches assume the choice alternatives are mutually exclusive over time, which is a questionable assumption. We introduced a new copula-based model (CO-CUB) for the transition probability, which can handle the dependent structure of best–worst choices while applying a very practical constraint. We used a conditional logit model to calculate the utility at consecutive time points and spread it to future time points under dynamic programming. We suggest that the CO-CUB transition probability algorithm is a novel way to analyze and predict choices in future time points by expressing human choice behavior. The numerical results inform decision making, help formulate strategy and learning algorithms under dynamic utility in time for best–worst DCEs.

Published: February 2024

Silvicultural treatment and the forest harvesting operations using different methods can lead to an increase in the production of runoff and sediment by changing the canopy and soil surface where they are conducted. In order to investigate this issue, sampling plots were established in the Namkhaneh district of the Kheyrud forest with three replications for every treatment: control stand and tree harvesting systems using single-selection cuttings and group-selection cuttings. The amount of runoff and sediment was collected and estimated from precipitation over a period of one year. Also, some soil physical properties such as bulk density, penetration resistance, sand, silt, and clay content, soil moisture, and soil organic matter were measured. The results showed that tree harvesting systems has a significant effect on runoff, the runoff coefficient, and sediment but the season (growing season and fall) and the combined effect of tree harvesting systems and the season have no significant effect on the runoff coefficient and sediment. The mean runoffs of each rainfall event for the control, single-tree, and group-selection treatments were 5.67, 8.42, and 10.28 mm, respectively, and the sediment amounts were 3.42, 6.70, and 11.82 gr/m2, respectively. Furthermore, the total annual erosion amounts of the control, selection, and grouping treatments were 0.427, 0.838, and 2.178 t/ha, respectively. The bulk density, penetration resistance, and percentage of sand and silt were positively related and the percentages of clay and organic matter were negatively related with the amount of runoff and sediment. In the method of individual selection cuttings, the damage to the forest in terms of the amount of runoff and soil erosion was less than for the group-selection cuttings. Forest harvesting by the selection method (single-selection and group-selection) has caused different changes in the vegetation canopy. The final summary of our results could be the advice to predominantly use the single-selection method in high-slope stands.

Published: February 2024

The purpose of this study is to analyze the characteristics of tourism economic links and networks within the tourism sector of China’s land border cities. It seeks to reveal the spatial and temporal evolution of tourism economic links in order to facilitate regional coordination among border cities. The article adopts the modified gravity model to measure the degree of tourism economic linkage of China’s land border cities, and utilizes UCINET 6.0 software, based on social network theory, to analyze the characteristics of the tourism economic linkage network of China’s land border. The findings show that the overall network density of China’s land border tourism economic linkages is relatively low, with uneven development in the “three borders” tourism economic linkages. There is a significant core–periphery structure, with the core area gradually expanding to the northwest and southwest, and geographically neighboring border cities are more likely to form a subgroup. The analysis of the socio-spatial network relationship of China’s land border cities yields suggestions for coordinated regional development, providing a foundation for the sustainable development of land border tourism.
Silaum silaus (L.) Schinz and Thell.—Habitat Conditions and Variation in Selected Characteristics of Populations at Different Densities
Authors: Stadnicka-Futoma Agata , Wójcik Tomasz , Jaźwa Małgorzata
Published: February 2024

Grasslands are one of the most diverse and species-rich ecosystems in the agricultural landscape of Central Europe. However, they are gradually being overgrown or transformed into arable fields due to their abandonment and the intensification of economic activities. This leads to a drastic decline in biodiversity and the disappearance of many rare species, e.g., Silaum silaus. Research on Silaum silaus populations was conducted in the years 2020 and 2022. Data were obtained from two Natura 2000 sites. The Jaćmierz site is located in a dispersed range of Silaum silaus in south-eastern Poland. The site at Zagórzyce is located in a dense range of the species in the south-western part of the country. Research on the habitat conditions was conducted on two permanent study surfaces with the dimensions of 10 × 10 m. This research included a soil study and measurements of herbaceous vegetation. To determine the habitat conditions, use was also made of Ellenberg ecological indicator values. At each site, 10 phytosociological relevés were conducted with the Braun-Blanquet method. In each study year, the manner of land use was determined. For detailed population study, one permanent surface of the dimensions 10 × 10 m was marked out, on which each year the generative and vegetative specimens were counted and biometric studies were conducted on 30 randomly chosen generative specimens. The species occurred in two different meadow communities (Arrhenatheretum elatioris, Molinietum caeruleae), which were characterised by different habitat conditions, and the greatest differences were evident in the chemical properties of the soil and in the method of management. The meadows at Jaćmierz were mowed twice a year, while at Zagórzyce mowing was performed once every two years. The communities were also varied in terms of flora, characterised by a high species richness and a high Shannon–Wiener index. Silaum silaus had significantly greater numbers and an over four times higher cover coefficient at Jaćmierz. The largest differences in the analysed traits of the species occurred in the case of generative traits. It was observed that management practices at Jaćmierz had a strong influence on the condition of specimens and the population size of Silaum silaus, which was much better preserved at this site.

Published: February 2024

Today, the increase in competition with globalization has caused logistics to gain importance, with international trade as one of its basic elements. Developments in the transportation and logistics sector affect economic growth through their effects on production, consumption, and trade. Similarly, international trade and economic growth also support the development of the transportation and logistics sector. From this perspective, logistics is an indicator of development. Nowadays, logistics is a constantly developing and growing sector. The aim of this study is to conduct performance rankings and cluster analyses of G20 countries in 2023 and to compare the results with the logistics performance index (LPI) scores published by the World Bank. Our assumption is that the results of the analysis and the LPI index would be the same or similar. The findings obtained as a result of both analyses are largely similar to the LPI ranking presented by the World Bank.
Designing a Sustainability Assessment Framework for Peruvian Manufacturing Small and Medium Enterprises Applying the Stakeholder Theory Approach
Authors: Córdova-Aguirre Luis Jesús , Ramón-Jerónimo Juan Manuel
Published: February 2024

Among the main obstacles affecting the competitiveness of Peruvian Small and Medium Enterprises (SMEs) are poor strategic planning and incipient use of management control systems that support the integration of sustainable practices for the growth of the organization. Not considering sustainability in the strategy and management control systems of Peruvian SMEs can jeopardize their stability and growth, as they are part of the supply chain of large companies that look for suppliers that comply with sustainability standards. Since manufacturing SMEs play a vital role in the economies and social welfare of countries, providing them with appropriate management tools to evaluate the sustainable performance of their activities is urgent to assure their survival. Thus, the aim of this study is to design a holistic sustainability assessment framework that enables Peruvian manufacturing SMEs to evaluate the full integration of sustainability into their business strategy and the creation of value for each stakeholder. Based on the gaps found in the literature review, a conceptual assessment framework was designed, then a multiple-case study was conducted in three Peruvian manufacturing SMEs in the plastic sector, and the data obtained were used to deploy the proposed conceptual assessment framework.
The Consolidation Stage of the Tourism Area Life Cycle (TALC) Model: The Case of Ibiza from 1977 to 2000
Authors: Ramón-Cardona José , Sánchez-Fernández María Dolores
Published: February 2024

Ibiza is an island in the Western Mediterranean internationally known as a sun and beach tourist destination, and it is notable for its nightclubs. This fact is the result of a century of tourist history that began in the first third of the 20th century and reached its maximum data at the end of that century and the beginning of the 21st century. Using the tourism area life cycle (TALC) model as a reference, it is possible to affirm that Ibiza has already gone through most of the stages proposed by the TALC. The objective of this work is to undertake a historical approach to the events and context that this island experienced during the period that could be considered to be a consolidation stage (1977 to 2000), which is still little analyzed. During this period, demand growth continued, although at a slower pace than in the previous stages, and suffered the first major crisis. The regional administration had to face the errors of the previous decades with various legal actions as follows: the limitation of the accommodation supply, which was already oversized by that stage; the environmental protection of spaces that had not yet been affected by urban development; the modernization of the offerings, much of them being obsolete and degraded; and the diversification of the issuing markets, which had until then been focused on Germany and the United Kingdom. The economic crisis of the early 1990s was a turning point for the tourism sector, both in terms of administrations and companies, and quantitative growth was replaced by qualitative growth in the following years. Starting in 2000, tourism in Ibiza entered a new phase characterized by the modernization of the offerings and the stagnation of data.
Ecological Status of Algeciras Bay, in a Highly Anthropised Area in South-West Europe, through Metal Assessment—Part II: Biotic Samples
Authors: Casanueva-Marenco María José , Galindo-Riaño María Dolores , Granado-Castro María Dolores , Díaz-de-Alba Margarita
Published: February 2024

Biotic samples from Algeciras Bay (South-west Europe) were studied to assess its ecological status, complementing the previous abiotic monitoring of trace metals in water and sediments. This bay is a densely populated area with intense port traffic and is highly industrialised with metal inputs. To study the impact of this, Zn, Cd, Pb, and Cu contents were determined in tissues of benthic (Solea senegalensis) and benthopelagic species (Scorpaena porcus, Trigloporus lastoviza, and Diplodus sargus sargus). Notable levels of Zn and Cu were found in the liver and gills of all fish species. Compared to international muscle guidelines, Pb sometimes exceeded the most restrictive values, outstanding S. porcus with 27% of samples above the permissible value. Metal pollution indexes revealed that the liver and gills of benthic species were more affected by metal pollution than benthopelagic species, especially in most industrialised sites. Particularly, S. senegalensis presented a higher accumulation factor from sediment of Cd and Cu in the liver (30.1 and 345.1), probably due to the close interaction as benthic species. Among the species studied, S. senegalensis and D. sargus sargus proved to be the best representative and useful bioindicators of metal-polluted environments as this bay. The results were consistent with the findings from the abiotic samples.
PFAS Modulate Osmotic Signaling Independent of Gravimetric Changes in the Rat Uterus
Authors: Dixon Aaron , Rowan Evelyn G. , Yackley Allison N. , Hines Erin P.
Published: February 2024

Various PFAS have been identified as potential endocrine-disrupting chemicals due to estrogen receptor activation, impacts on puberty timing, or impacts on hormonally sensitive endpoints in fish. This study screened multiple PFAS in the rat uterotrophic assay to determine potential estrogenic effects on the uterus with PFAS exposure. This study also explored PFAS-dependent uterine signaling with an osmotic stress mRNA gene expression array. Briefly, Sprague–Dawley rats (26–39 days old) were ovariectomized, and uterine tissue was allowed to regress for a 3-week period of recovery. Animals were then exposed daily via oral gavage to PFAS for 4 days, and then uterine weight was determined. In contrast to the positive control estrogens, the PFAS tested (4:2, 6:2, and 8:2FTOH; perfluorooctanesulfonamide (PFOSA), perfluorononanoic acid (PFNA), perfluorohexane sulfonate (PFHxS), perfluorooctane sulfonate (PFOS), nafion byproduct 2 (NBP2), 1H,1H,8H,8H-perfluorooctane-1,8-diol (FC8-diol) and 1H,1H,10H,10H-perfluorodecane-1,10-diol (FC10-diol)) caused no significant changes in the uterine weight. Hormonally active compounds can act as carcinogens, and because earlier rodent work has demonstrated that chronic PFOA exposure is associated with increased risk of uterine cancer, uterine mRNA gene expression was explored with an osmotic stress RT-qPCR array. PFAS exposure significantly upregulated multiple genes across the array, with PFOSA being the compound most similar to the reference estrogens (estradiol benzoate and ethinyl estradiol) in its expression pattern. Also, across all PFAS, pathway analysis revealed that the paxillin pathway, a pathway important in tumor suppressor gene SHP-2 signaling, was significantly upregulated with PFAS exposure. These results demonstrate that in vitro estrogen screens or impacts in fish may show different responses from direct impacts on mammalian uterine weight as assessed with the uterotrophic assay. This study also builds out new mechanisms that may contribute to understanding of carcinogenic changes seen in the uterus after PFAS exposure.

Authors: Komínková Marcela , Ben Mansour Karima , Komínek Petr , Brožová Jana , Střalková Radomíra
Published: February 2024

This study focused on the viruses of the Tymoviridae family that infect grapevines in the Czech Republic. Complete sequences of GFkV (grapevine fleck virus) and GRGV (grapevine red globe virus) from the genus Maculavirus and GRVFV (grapevine rupestris vein feathering virus) and GSyV-1 (grapevine Syrah virus 1) from the genus Marafivirus were obtained using high-throughput sequencing of small RNAs and total RNAs. Mixed infections with these viruses were observed, as well as several variants of these viruses in the same plant. Phylogenetic analysis showed the position of the newly obtained virus isolates within the Tymoviridae family. Recombinant analysis provided evidence of single and multiple intraspecific recombinations in GRGV, GSyV-1, and GRVFV. Additionally, GAMaV, a grapevine virus from the genus Marafivirus, was reported for the first time in the Czech Republic.

Published: February 2024

Background and Aims: Treatment with siRNAs that target HBV has demonstrated robust declines in HBV antigens. This effect is also observed in the AAV-HBV mouse model, which was used to investigate if two cycles of GalNAc-HBV-siRNA treatment could induce deeper declines in HBsAg levels or prevent rebound, and to provide insights into the liver immune microenvironment. Methods: C57Bl/6 mice were transduced with one of two different titers of AAV-HBV for 28 days, resulting in stable levels of HBsAg of about 103 or 105 IU/mL. Mice were treated for 12 weeks (four doses q3wk) per cycle with 3 mg/kg of siRNA-targeting HBV or an irrelevant sequence either once (single treatment) or twice (retreatment) with an 8-week treatment pause in between. Blood was collected to evaluate viral parameters. Nine weeks after the last treatment, liver samples were collected to perform phenotyping, bulk RNA-sequencing, and immunohistochemistry. Results: Independent of HBsAg baseline levels, treatment with HBV-siRNA induced a rapid decline in HBsAg levels, which then plateaued before gradually rebounding 12 weeks after treatment stopped. A second cycle of HBV-siRNA treatment induced a further decline in HBsAg levels in serum and the liver, reaching undetectable levels and preventing rebound when baseline levels were 103 IU/mL. This was accompanied with a significant increase in inflammatory macrophages in the liver and significant upregulation of regulatory T-cells and T-cells expressing immune checkpoint receptors. Conclusions: Retreatment induced an additional decline in HBsAg levels, reaching undetectable levels when baseline HBsAg levels were 3log10 or less. This correlated with T-cell activation and upregulation of Trem2.
Default Reference Frames for Angular Expansion in the Perception of Visual Direction
Authors: Tardeh Prince U. D. , Xu Crystal , Durgin Frank H.
Published: February 2024

Prior work has shown that perceived angular elevation relative to a visible horizon/ground plane is exaggerated with a gain of about 1.5. Here, we investigated whether estimates of angular elevation remain exaggerated when no such visual gravitational reference is provided. This was investigated using a series of five experiments, with most using a novel apparatus to view a large field-of-view stereoscopic virtual environment while lying supine, looking straight up. Magnitude estimation methods were used as well as psychometric matches to internal standards with a total of 133 human participants. Generally, it was found that the exaggerated scaling of elevation seemed to be a default for 3D space, even if testing was performed in virtual environments that were nearly empty. Indeed, for supine observers, a strong exaggeration was found even for azimuthal judgments, which is consistent with the idea that, when looking upward, all deviations are in elevation. This suggests that the overarching gravitational frame often serves as a default reference frame.
Effects of Freeze–Thaw Cycles on Soil Nitrogen Transformation in Improved Saline Soils from an Irrigated Area in Northeast China
Authors: Nie Siyu , Jia Xian , Zou Yuanchun , Bian Jianmin
Published: February 2024

Freeze–thaw cycles (FTCs) occur during the nongrowing season, and residual nitrogen (N) increases the risk of N loss with melting water. To study the effect of FTCs on soil N, rice fields in improved irrigated saline soil in northeast China were selected as the research subjects. Water content (10%, 20%, and 30%), different N fertilizer levels (180 and 220 kg/ha), and multiple FTCs of soil samples were used to clarify the effects of N fertilizer application and water content on N efficiency. The results indicate that, after the third FTC, the soil ammonium nitrogen (NH4+-N) level increased significantly. NH4+-N increased with an increase in the initial soil moisture content and decreased with fertilizer levels. Nitrate nitrogen (NO3−-N) decreases with increasing initial soil moisture. The inorganic N increased significantly compared with that in the unfrozen stage, indicating that FTCs promote soil N mineralization. However, high fertilization rates inhibit mineralization. Analysis of variance showed that NO3−-N is sensitive to the N application rate, water content, and salinity (p < 0.05). FTCs and artificial fertilization are the factors that affect N mineralization (p < 0.05). The research results are significant for preventing nitrate leaching and soil acidification during spring plowing and providing a scientific basis for fertilization systems and water environment pollution in improved saline soils.

Authors: Liu Jingjing , Zha Xiaoting , Yang Yajie
Published: February 2024

Diabetes mellitus is one of the common chronic diseases, seriously threating to human health. The continuous monitoring of blood glucose concentration can effectively prevent diabetic diseases. The sensing performance of glucose non-enzymatic sensors is mainly determined by working electrode materials. Metal–organic frameworks (MOFs) are recognized as promising candidate for glucose sensor application, due to its large surface areas, ordered porous structure and nearly infinite designability. In this review, the sensing performance, research progress and future challenge of non-enzymatic glucose sensors based on MOF-based materials in recent years are presented. We hope that this review would provide valuable technology guidance for high performance non-enzymatic glucose sensors based on MOFs.

Un casque inédit de la basse époque hellénistique conservé au Musée de Prilep
Authors: Juhel Pierre
Published: February 2024

Ce casque, conservé au Musée de Prilep (République de Macédoine), fut trouvé dans une tombe de la basse époque hellénistique, lors de fouilles yougo-polonaises menées au nord de la Pélagonie en 1972. C’est une arme de fer dont, semble-t-il, aucun exemplaire de ce type n’a été exhumé à ce jour. Suivant un parallèle iconographique patent et du fait du matériel funéraire associé (qui paraît perdu), il s’agissait vraisemblablement du casque d’un officier de cavalerie. Cet officier devait relever de ces troupes que les Macédoniens, après la fin du royaume antigonide encore, entretenaient pour défendre leurs confins des incursions barbares.
Lactance et les Academica de Cicéron : citations et polémiques
Authors: Van der Meeren Sophie
Published: February 2024

L’article passe en revue les emprunts aux Academica chez Lactance : celui-ci détourne constamment le texte de Cicéron de son contexte pour l’adapter à son œuvre propre, et le réinterprète dans une optique souvent étrangère aux Academica. Emprunts et réélaborations visent des fins multiples : critique d’un dogmatisme ou d’un scepticisme outranciers, attaque de la philosophie païenne dans son ensemble. Mais Lactance reprend aussi à Cicéron des méthodes jugées salutaires : la confrontation des diverses opinions philosophiques, l’argumentation in utramque partem ; le doute lui-même est valorisé comme démarche heuristique et symbole de l’humilité humaine devant une vérité révélée que nous ne pouvons connaître par nous-mêmes.
Augustin lecteur de Cicéron dans le Contra Académicos
Authors: Bouton-Touboulic Anne-Isabelle
Published: February 2024

This paper will examine Augustine’s reading of Cicero’s Academica in his Contra Academicos. He argues that certain rhetorical and linguistic signs in the Ciceronian text show that the New Academicians, who claimed to be Sceptics, were secretly dogmatic Platonists. His historical and allegorical interpretation of the Old Testament and his general conception of reading throw further light on this idea.
Le praefectus praesidii sous la République. Quelques cas d’étude

Published: February 2024

Des termes comme praefectus praesidii ou φρούραρχος ont, parmi d’autres, été employés pendant la République pour se référer aux responsabilités confiées à un représentant officiel romain chargé d’une garnison dans une ville, indépendamment de son rang. Les garnisons ont entretenu un lien de plus en plus étroit avec la logistique de l’armée romaine, et aussi avec la conduite de la politique extérieure. Ces chefs de garnisons ont pu parfois agir en instruments politiques de l’impérialisme romain vis-à-vis des villes pérégrines dont ils avaient la charge.
Integrated Actuation and Sensing: Toward Intelligent Soft Robots
Authors: Zhou Shuai , Li Yuanhang , Wang Qianqian , Lyu Zhiyang
Published: February 2024

Soft robotics has received substantial attention due to its remarkable deformability, making it well-suited for a wide range of applications in complex environments, such as medicine, rescue operations, and exploration. Within this domain, the interaction of actuation and sensing is of utmost importance for controlling the movements and functions of soft robots. Nonetheless, current research predominantly focuses on isolated actuation and sensing capabilities, often neglecting the critical integration of these 2 domains to achieve intelligent functionality. In this review, we present a comprehensive survey of fundamental actuation strategies and multimodal actuation while also delving into advancements in proprioceptive and haptic sensing and their fusion. We emphasize the importance of integrating actuation and sensing in soft robotics, presenting 3 integration methodologies, namely, sensor surface integration, sensor internal integration, and closed-loop system integration based on sensor feedback. Furthermore, we highlight the challenges in the field and suggest compelling directions for future research. Through this comprehensive synthesis, we aim to stimulate further curiosity among researchers and contribute to the development of genuinely intelligent soft robots.

Teh merupakan salah satu komoditas andalan subsektor perkebunan yang memegang peranan penting dalam perekonomian Indonesia. Teh berperan sebagai penghasil devisa ekspor sebesar 108,5 juta USD di tahun 2018 atau setara 1,5% dari PDB sektor pertanian. Kabupaten Garut salah satu sentra produksi teh Indonesia memanfaatkan teh untuk industri pabrik Teh Kejek. Upaya dalam mengelola agroekosistem teh supaya produktif adalah dengan mempelajari struktur agroekosistem misalnya keberadaan serangga dan arthropoda lainnya. Penelitian ini bertujuan untuk mengetahui indeks keanekaragaman dan dominansi serangga dan arthropoda lainnya serta peranannya di perkebunan teh. Penelitian dilaksanakan di Desa Sukahurip, Cigedug, Garut pada bulan Desember 2021 – Januari 2022. Penelitian menggunakan metode kuantitatif deskriptif dengan mengaplikasikan perangkap; 24 yellow bottle sticky trap dan 18 pitfall trap. Hasil penelitian menunjukkan bahwa keanekaragaman serangga dan arthropoda lainnya (yellow bottle sticky trap) adalah 0,348 kategori rendah dengan 9 ordo, sedangkan serangga tanah (pitfall trap) adalah 1,320 kategori sedang dengan 10 ordo. Dominansi serangga dan arthropoda lainnya (yellow bottle sticky trap) adalah 0,865 kategori tinggi dengan yang mendominansi serangga ordo Diptera, sedangkan (pitfall trap) adalah 0,371 kategori rendah dengan yang mendominansi arthropoda ordo Collembola. Pada yellow bottle sticky trap lebih banyak memerangkap B. dorsalis yang bukan merupakan hama utama pada tanaman teh. Hal tersebut dikarenakan sistem tanam polikultur dengan tanaman inang B. dorsalis dan yellow bottle sticky trap kurang efektif memerangkap serangga dan arthropoda lainnya pada tanaman teh. Peranan serangga dan arthropoda lainnya dalam agroekosistem teh yakni sebagai herbivora (hama), karnivora (predator dan parasitoid), detritivor (pengurai), dan polinator (penyerbuk). Agroekosistem teh Desa Sukahurip, Cigedug, Garut dengan teknik yellow bottle sticky trap didominansi oleh spesies serangga lalat buah (Bactrocera dorsalis) berperan sebagai herbivora (hama), sedangkan dengan teknik pitfall trap adalah ekor pegas (Isotomurus balteatus) berperan sebagai detritivor (pengurai).

Authors: Ajizah Nur
Published: February 2024

Penelitian ini merupakan penelitian yang memiliki tujuan untuk menilai atau menguji pengaruh variabel bebas (Firm Size, Pertumbuhan Penjualan, Rasio Hutang) terhadap variabel dependen  (Stuktur Modal). Struktur Modal dilihat dari Debt to Equity Ratio (DER).  Hasil pengujian hipotesis didapatkan kesimpulan bahwa  Firm Size dan Pertumbuhan Penjualan tidak memiliki pengaruh yang signifikan terhadap Struktur Modal, sedangkan Rasio Hutang  berpengaruh secara signifikan pada Struktur Modal, artinya rasio hutang yang merupakan perbandingan antara total hutang dengan total aktiva sangat berdampak pada perubahan naik turunnya struktur modal. Semakin tinggi rasio hutang maka semakin tinggi struktur modal, begitu juga sebaliknya.
Cereales ultraprocesados: Un estudio de métodos visuales sobre su comunicación en redes, comparativo entre Francia y México: Uso de cámara colaborativa y eye tracking
Authors: Prado-Hurtado Ricardo Ignacio
Published: February 2024

Los cereales ultraprocesados (CP) son productos que, en la percepción de la sociedad, se sitúan en una zona ambigua entre lo beneficioso y lo perjudicial para la salud. En este estudio se emplean las técnicas de cámara colaborativa y seguimiento ocular con jóvenes de la ciudad de México y Chambéry, con el propósito de entender sus reacciones principales ante la publicidad de cereales altamente procesados en la plataforma sociodigital YouTube. En esta investigación se observan comportamientos similares en los jóvenes. La cámara colaborativa ayudará a identificar patrones de comportamiento involuntario, respuestas físicas y los códigos de comunicación no expresados por otros métodos utilizados por los jóvenes para categorizarlos. Esto permite establecer posibles conexiones entre diversas situaciones y contextos, que podrían utilizarse en la creación de mensajes de salud más efectivos y beneficiosos para la comunicación.
Sorting Fact from Fiction: A Critical Review and Revision of Hausa Minimal Pairs in Phonological Literature
Authors: M.A. Umar, , I. Muhammad,
Published: February 2024

This research addresses the issues surrounding Hausa minimal pairs, aiming to separate fact from fiction in existing literature and provide a solid foundation for phonological analysis. By consulting trustworthy dictionaries and engaging with native speakers, we validate and refine our analysis of minimal pairs. Our study identifies and analyzes valid minimal pairs, highlighting the fundamental phonemes and their impact on meaning. We also eliminate inaccurate pairs and explore expanded minimal sets and suprasegmental pairs to further enrich our understanding of sound and tone in Hausa. Our findings contribute to a better understanding of the interplay between phonemes and meaning in the Hausa language. In light of our research, we propose a corrected table of Hausa minimal pairs, addressing inaccuracies and inconsistencies found in previous studies. We also emphasize the need for meticulous analysis and careful interpretation when identifying and interpreting minimal pairs, as ambiguities may arise. This calls for collaboration with experts and transparent documentation of revisions to ensure uncompromising accuracy. The dissemination of reliable examples of minimal pairs is crucial for their proper use in research, education, and technological applications. We advocate for the promotion of these examples and the awareness of their importance in understanding the sound patterns and internal structure of the Hausa language.

Authors: A Busa, M. , A. Umar,
Published: February 2024

The study is titled “The Effects of Interactive Instructional Television on Upper Basic Students’ Academic Achievement in Hausa Language. The study was quasi-experimental and specifically, the non-equivalent comparison group design was adopted. The study used 120 Upper-Basic II from Minna Educational Zone, Niger State. The study answered two (2) questions and tested two (2) null hypotheses. Hausa Language Achievement Test (HALAT) was the data collection instrument. Expert duly validated the instrument and has a reliability coefficient index power of 0.780. The mean and standard deviation were equally used to answer the questions raised by the study. The independent sample t-test was used to test the study’s null hypotheses at 0.05 alpha. The study discovered significant differences between the academic achievement scores of the experimental and the comparison groups. By implication the upper basic students taught Hausa language with interactive instructional television outperformed their counterparts taught with lecture technique. The study found that gender does not affect the performances of the experimental group signifying that the students who were taught the Hausa language with interactive instructional television performed credibly well irrespective of their gender. In light of the above, the study recommends Hausa language teachers should be encouraged to use interactive instructional television in their classrooms for their students’ optimum academic excellence in Niger State; Niger State government, through the Ministry of Education, donor Agencies and influential individuals should support and provide all the funds needed for the procurement and maintenance of instructional television for maximum efficiency and service delivery.
