Euler's totient function applied to complete hypergroups
Authors: Sonea Andromeda , Cristea Irina
Published: January 2023

We study the Euler's totient function (called also the Euler's phi function) in the framework of finite complete hypergroups. These are algebraic hypercompositional structures constructed with the help of groups, and endowed with a multivalued operation, called hyperoperation. On them the Euler's phi function is multiplicative and not injective. In the second part of the article we find a relationship between the subhypergroups of a complete hypergroup and the subgroups of the group involved in the construction of the considered complete hypergroup. As sample application of this connection, we state a formula that relates the Euler's totient function defined on a complete hypergroup to the same function applied to its subhypergroups.
The critical delay of the consensus for a class of multi-agent system involving task strategies
Authors: Chen Yipeng , Liu Yicheng , Wang Xiao
Published: January 2023

The time delay may induce oscillatory behaviour in multi-agent systems, which may destroy the consensus of the system. Therefore, the critical delay that is the maximum value of the delay to guarantee the consensus of the system, is an important performance index of multi-agent systems. This paper studies the influence of the processing delay on the consensus for a class of multi-agent system involving task strategies. The first-order system with a single delay and the second-order system with two different delays are investigated respectively. A critical delay independent of strategies and a critical region of the 2-D plane that depends on strategies is obtained for the first-order and the second-order system respectively. Specifically, a geometric method was used for the case of two different delays. Several numerical simulations are presented to explain the results.
L’intégration sociale des élèves de classe d’accueil : Une approche écologique
Authors: Richard Dominik
Published: January 2023

J’ai construit cet article en m’appuyant sur mon expérience de recherche doctorale qui a mis en évidence l’importance d’adopter une approche écologique pour la compréhension par les enseignants titulaires de classe d’accueil du processus d’intégration sociale des élèves immigrants. Le but de cette recherche était de comprendre le phénomène d’appropriation du nouveau « milieu de vie » par une démarche permettant d’en montrer la face cachée et toute la complexité. La dimension compréhensive et collaborative de celle-ci s’est avérée fondamentale dans la démarche socio-constructiviste adoptée, « pour, par et avec » les participantes et l’enseignante du milieu d’accueil où s’est déroulée cette recherche. Les résultats indiquent, entre autres, que les élèves privilégient l’usage de stratégies d’appropriation à caractère transgressif par rapport à l’institution d’accueil. Le cadre scolaire, disposant de peu de moyens, a recours en effet à une démarche administrative d’intégration qui semble aller à l’encontre des principes appropriatifs. Dans ce contexte, la pratique théâtrale a pu contribuer à réduire l’écart ainsi créé en établissant une dynamique de socialisation horizontale entre les élèves et l’enseignante. À l’issue de cette recherche, je suis en mesure de suggérer aux établissements scolaires qui accueillent des élèves immigrants de diversifier les modalités de socialisation et d’institutionnaliser leur accueil dans une perspective trans-systémique en établissant, entre autres, un trialogue entre enseignants, élèves et familles. En guise de conclusion, j’apporterai quelques éléments de réponse à la question suivante : ce projet de recherche s’inscrit-il dans une optique d’éducation relative à l’environnement ?
Nicolas Laurence, La contestation portée par les innovations monétaires comme moteur de changement institutionnel. Le cas des monnaies locales et des cryptomonnaies
Authors: Laurence Nicolas
Published: January 2023

Certaines innovations monétaires portent en elles une contestation du système monétaire existant. Les monnaies locales et les cryptomonnaies participent à cette dynamique. Les monnaies locales véhiculent une contestation monétaire axée sur les aspects sociaux et l’écologie à l’échelon territorial et local, alors que les cryptomonnaies, dont le Bitcoin est l’initiative la plus emblématique, remettent en cause le système monétaire en proposant des alternatives transnationales grâce à une technologie – la blockchain. La thèse vise à démontrer que ces deux innovations monétaires radicalement différentes véhiculent des projets politiques alternatifs qui participent à un même processus d’émergence de nouveaux espaces monétaires potentiellement porteurs de changement institutionnel.La contestation portée par ces innovations monétaires est d’abord saisie dans sa dimension discursive, avant d’être analysée à travers des entretiens semi-directifs et des actes juridiques, lorsqu’elle prend la forme d’actions collectives. Le recours à une économie politique de la monnaie nous permet de questionner la place des rapports de force et des conflits dans le processus de changement de l’institution monétaire.
Le rôle des acteurs de la société civile dans le déploiement des projets économiques et politiques alternatifs : l’expérience mexicaine de la 4T
Authors: Bertoli Max-Amaury , Morvant-Roux Solène , Bizberg Ilán
Published: January 2023

Alors qu’en 2018, la vague d’indignation causée par les décennies de politiques néolibérales et corporatistes se fédère autour du projet de réforme d’Andrés Manuel López Obrador, les mesures mises en place par le nouveau président mexicain rompent rapidement sa promesse post-néolibérale. En effet, l’imposition de l’austérité républicaine, la centralisation opérationnelle de l’appareil public et la négation des organisations de la société civile sur lesquelles se base le nouveau gouvernement, toutes justifiées par la lutte contre la corruption, réduisent fortement sa portée transformatrice. À partir d’une approche socio-économique articulant différentes échelles d’analyse, cet article propose un regard critique sur les traits principaux de ce projet politique à travers l’étude d’un de ses programmes publics phares : Sembrando Vida. Malgré une approche agroécologique innovante, nous montrons que ce programme tombe dans une vision réductrice et homogénéisante des territoires et des communautés en refusant de prendre en compte le rôle primordial de la réciprocité, de la solidarité horizontale et des dynamiques collectives préexistantes, au même titre que la politique générale de López Obrador, tous deux ne parvenant pas à sortir d’une opposition stérile entre l’État et le Marché.
Crises, informalité et reconfigurations du marché du travail : quatre décennies de bouleversements économiques au Brésil
Authors: Razafindrakoto Mireille , Roubaud François , Saludjian Alexis
Published: January 2023

Cet article analyse les ajustements du marché du travail brésilien sur longue période, notamment lors des épisodes de crise macroéconomique, qui s’étendent sur plus du tiers des quarante dernières années. L’un des objectifs est de soumettre les différentes théories de l’informel à l’épreuve des faits, et tout particulièrement l’hypothèse du rôle anticyclique que lui attribue la thèse dualiste. Sur le plan empirique, notre approche est basée sur un important travail d’« archéologie statistique » de reconstitution de séries historiques et de traitement de première main de millions d’observations de microdonnées d’enquêtes ou de registres administratifs. Les trois angles d’analyse adoptés convergent. Nous montrons entre autres la formidable résilience du marché du travail brésilien qui s’inscrit dans l’histoire et les disparitions progressives depuis les années 1990 des mécanismes de la crise « canonique », supplantée par un processus d’exclusion multiforme, et des frontières entre formel et informel, en défaveur des droits des travailleurs. Cependant, les crises ne sont pas toujours le meilleur point d’observation : la phase de croissance des années 2000, par exemple, apparaît comme la seule période « transformative » qui a laissé une empreinte positive et durable sur le monde du travail.
Performance et rareté des coopératives de travailleurs : contributions empiriques à partir du cas français (Scop)
Authors: Mirabel Thibault
Published: January 2023

La thèse compare la performance des coopératives de travailleurs (Scop) et des entreprises conventionnelles. Ces deux types d’entreprise diffèrent par leur distribution des droits de propriété et leur mode de gouvernance. Au sein des Scop, les travailleurs ont le contrôle ultime de leur entreprise, tandis qu’au sein des entreprises conventionnelles, les investisseurs ont ce contrôle. Les Scop instituent la démocratie dans le monde économique. Malgré leur attractivité, elles représentent une fraction minuscule des entreprises dans le monde (2 400 en France). Cette thèse entend apporter des éléments nouveaux pour comprendre la rareté des Scop. Le chapitre 1 montre que la probabilité de créer une Scop est maximale lorsque le coût irrécupérable en travail est dominant et que le coût irrécupérable en capital est négligeable. Le chapitre 2 montre que les Scop survivent plus longtemps que les entreprises conventionnelles, indépendamment du fait que leurs ressources à l’entrée diffèrent ou non. Le chapitre 3 montre que les reprises en Scop, même d’entreprises en difficulté, survivent plus longtemps que les Scop nouvellement créées. Dans l’ensemble, cette thèse suggère que la rareté des Scop est due à des barrières à l’entrée spécifiques aux Scop, plutôt qu’à leur prétendue moindre performance vis-à-vis des entreprises conventionnelles.
Crisis and reconfiguration: economic and political changes in the Brazilian accumulation regime in the XXI century
Authors: Bandeira de Mello Filho Marcelo Soares , Santos Diogo Oliveira
Published: January 2023

The main objective of this work is to demonstrate that Brazil has experienced, since the end of 2016, a reconfiguration of the financial and extractive accumulation regime and a change in the ruling power bloc. Based on the Regulation Theory, an analysis of the Brazilian economy is carried out to understand the current transformations. The recent liberal reforms are assessed to demonstrate how they imply an accumulation regime reconfiguration, affecting institutional forms and consolidating the power bloc hegemonized by the agrarian and financial bourgeoisie. Among other effects, these reforms deepen State subordination to the monetary and financial regime, expand the control of the bourgeoisie over the wage relation and reinforce the commodity-exporting sector. It is concluded that the ongoing reconfiguration increases the country’s dependence on international economic and financial cycles because it takes necessary instruments of economic intervention away from the State. Moreover, it reduces internal control over the competition with foreign companies in the national territory, reinforces the commodity-exporting sector and makes mass consumption more pro-cyclical. This reconfiguration implies a partial reversal in the internalization of the dynamic centre of Brazilian capitalism that occurred during the import substitution industrialization process.
Financialized growth regime and capital accumulation in Brazil: geopolitical and institutional factors of the recent collapse and beyond
Authors: Bruno Miguel , Gentil Denise
Published: January 2023

This paper discusses the factors that contributed to the collapse of the hegemonic bloc that enabled the governability of the Workers’ Party in the period 2003-2016. It is based on the view that in order to understand the economic and political-institutional crisis, it is necessary to analyze the deepening financialization of Brazil, a periphery country, and the way in which rentier accumulation operates in the consolidation of US power in Latin America. The empirical evidence revealed the existence of endogenous factors for the crisis, factors that were already present in the Brazilian economy before the cyclical deterioration that started in 2014. With the end of the commodity price boom, profit and accumulation rates began declining. The recession that started in 2015, coupled with the social discontent stimulated by mainstream media, was conveniently used by national economic groups aligned with the geopolitical interests of the hegemonic nation, the US and its allies. This is representative of a hybrid war aimed at the Workers’ Party government. The econometric results, in addition to corroborating this interpretation, detected the existence of an export-led growth regime between 2001 and 2019 that articulates with financial interests. This is the result of the strong external demand for Brazilian commodities, which refutes the interpretations that considered it a typical finance-led growth or, in a surprisingly optimistic perspective for a country marked by a high concentration of income and stock of wealth, a wage-led growth regime.
Developing World-Class Internationalized Universities
Authors: El-Amin Abeni , Yuzhou Cai
Published: January 2023

Effective higher education leadership is a movement in internationalized higher education. Moreover, incorporating principles of internationalized higher education is a contrast from traditional graduate educational practices, because new assessment methodologies are utilized to demonstrate institutional aptitude. Additionally, there has been a critical move in cutting-edge economies on how to attract students, grants, and funders. Globally, access to internationalized higher education has grown exponentially. Innovation is changing the idea of how people define internationalized higher education. Centralized leadership, information sharing, cooperation, and advancement are more prevalent than prior. Internationalized higher education has superseded traditional educational notions. Achievement lies in the capacity to impart, offer, and utilize data analytics to mitigate complex issues; to adapt to evolving conditions; to marshal the wave of innovation, and to promote new educational management techniques.
Concomitant Hodgkin’s Lymphoma in a Patient with Tuberculous Spondylitis
Authors: Reddy Ravikanth
Published: January 2023

Concomitant Hodgkin’s lymphoma with tuberculosis is an exceedingly rare clinical scenario and a condition that is difficult to manage due to similar clinical presentation. This case report describes the same in a 44-year-old male patient diagnosed with Koch’s and initiated on antituberculosis therapy, based on confirmation of findings from the spine biopsy and culture. The patient’s clinical condition worsened despite being on treatment for tuberculosis. Hence, further work up of the patient was done which included mediastinoscopy and endobronchial ultrasound. Biopsy samples from a conglomerate mass in the lower cervical region and mediastinum revealed Hodgkin’s lymphoma of the nodular sclerosis type. This time, the patient showed significant improvement following treatment with chemotherapy and radiotherapy along with antituberculosis therapy.
Utility of Hematological and Biochemical Parameters as a Screening Tool for Assessing Coronavirus Disease 2019 Infection and its Severity
Authors: Alam Sana , Khan Sabina , Jain Vineet , Kashyap Varun , Kapur Prem
Published: January 2023

Background:

The rapidly evolving pandemic of Coronavirus disease 2019 (COVID-19) has presented with clinical severity, which varies from asymptomatic cases to being fatal in others. The need of the hour is to find meaningful and cost-effective COVID-19 biomarkers out of conventional hematological and biochemical parameters, which will help in the early identification of patients with a poor prognosis, leading to timely intervention.

Aim:

The aim was to analyze different biochemical and hematological parameters in COVID-19 patients and also to study the association of these parameters with disease severity.

Materials and Methods:

Cross-sectional observational study was carried out on 100 COVID-19 patients from a hospital from July to October 2020. Based on saturation of oxygen (SpO2), admitted patients were grouped into mild–moderate (SpO2 ≥90%) and severe groups (SpO2 <90%). Hematological and biochemical parameters were studied in both groups, and association with disease severity was analyzed.

Results:

Out of 100 patients, 57 patients were seen in the mild–moderate group (SpO2 ≥90%), while 43 patients (SpO2 <90%) belonged to the severe category. Males were predominant in both mild–moderate and severe groups. Among the hematological parameters, statistically significant higher values of absolute neutrophil count (P = 0.046) and significantly lower absolute lymphocyte count (P = 0.003) values were observed. With regard to biochemical parameters, increased urea and decreased total protein were found in the severe category and this association was statistically significant.

Conclusion:

To conclude, early identification and monitoring of hematological and biochemical parameters, especially those associated with higher disease severity, may contribute toward improving disease outcomes.
Cell of Origin Classification of Diffuse Large B-Cell Lymphoma
Authors: Dhar Lity , Singh Sarika , Jain Shyam Lata , Vindal Anubhav , Sinha Pallavi , Gautam Rashmi
Published: January 2023

Context:

Diffuse large B-cell lymphoma (DLBCL) is a neoplasm of medium-to-large B lymphoid cells with diffuse growth patterns. Although it is a potentially curable disease, around 40% of the cases are either refractory to primary treatment or relapse. Based on gene expression profiling (GEP), DLBCL can be classified as germinal center B-cell subtype (GCB) and activated B-cell subtype (ABC). About 10%–15% of cases do not convincingly fall into either of the two subtypes and hence remain unclassified. Most widely used and suggested by WHO is Hans algorithm comprising immunohistochemical markers CD10, B-cell lymphoma6 (BCL6), and IRF4/MUM1, which classifies CD10+ and CD10-/BCL6+/MUM1-DLBCL as GCB, while CD10-/BCL6+/MUM1 + and BCL6-DLBCL as non-GCB.

Aims:

The aim of this study was to classify DLBCL into GCB and non-GCB subtypes using Hans Algorithm.

Settings and Design:

This was a retrospective study.

Materials and Methods:

Twenty-eight histologically diagnosed cases of nodal (71.4%), as well as extranodal (28.6%) DLBCL, were taken over the period of 2 years with age ranging between 10 and 65 years with 19 males and 9 females. M: F = 2.1:1. Depending upon the site involved, a primary panel of immunohistochemistry (IHC) markers, namely CD20, CD3, LCA, EMA, and CK, followed by a secondary panel comprising CD10, CD19, CD30, LMP1, BCL2, BCL6, MUM1, MYC, and FOXP1 was used.

Results:

In this study, it was found that the non-GCB subtype was more common than the GCB subtype in Indian population.

Conclusions:

Although the gold standard of GEP to assign cells of origin is using RNA microarray analysis, however, due to resource constraints and other limitations such as long turnaround times, IHC is the next acceptable alternative.
Giant Placental Chorioangioma in a Young Patient Causing Adverse Fetal Outcome
Authors: Wadhwa Shagun , Dixit Sonali , Sharma Sonal
Published: January 2023

Chorioangiomas are benign vascular tumors of the placenta originating from chorionic tissue. They are also known as hemangiomas of the placenta. They occur in approximately 0.5%–1% of all pregnancies. Large chorioangiomas are rare and may lead to serious fetal and maternal complications. Here, we are describing a case of giant placental chorioangioma in a 19-year-old young female (G2A1) who presented to us at 39 weeks of gestation with decreased fetal movements. Ultrasound examination revealed an enlarged placenta with a well-defined 9.4 cm × 9.3 cm heteroechoic area with increased vascularity. Cesarean section was performed in view of fetal distress and a female baby weighing 1.6 kg was delivered. The newborn died within 2 weeks due to pulmonary hypoplasia and hemodynamic failure. The diagnosis of chorioangioma was confirmed with histopathology. This case depicts the necessity of early diagnosis, close fetal monitoring, and timely intervention in achieving a favorable pregnancy outcome.
Dendritic Cell-Based Immunity: Screening of Dendritic Cell Subsets in Breast Cancer-Bearing Mice
Authors: Aldahlawi Alia M , Zaher Kawther Sayed Ali
Published: January 2023

Background:

Breast cancer (BC) is the most devastating disease, particularly the lethal invasive form. It is the most underlying cause of death among women worldwide. The expansion of BC is controlled by a variety of alterations in the tumor cells themselves, in addition to the state of the immune system, which has a direct influence on the tumor microenvironment. Numerous receptors expressed by T-cells interact with ligands on antigen-presenting cells to provide activation signals results in mounting effector anti-tumor T-cell responses. On the other hand, there is a dearth of information about the actual interactions and reactions of T-cells and dendritic cells (DCs) all through the progression of tumor development.

Aim:

Immune system response against BC was investigated through tumor induction in mice. The size and volume of the tumor were calculated. Moreover, the phenotypical profile of T-cells and DCs from lymph nodes (LN) and spleens of BC-bearing mice was investigated. In addition, the levels of Transforming growth factor-β, Interferon-gamma (IFN-γ), Interleukin IL-2, IL-10, IL-4, IL-12, and tumor necrosis factor (TNF)-α were determined.

Materials and Methods:

MDA231 cells were utilized to induce BC in 30 white BALB/C mice, whereas the other 30 mice acted as healthy controls and were not treated with any cancer-causing agents. The impact of malignancy was evaluated using flow cytometry based on the marking surface molecules, as well as the titer of specific cytokines of the mice’s LN culture using the ELISA method. These cytokines included transforming growth factor-β (TGF-β), IFN-γ, IL-2, IL -10, IL -4, IL -12, and TNF-α.

Results:

The findings showed that the maturation of DCs was inhibited, followed by an accumulation of immature DCs. These immature DCs increase the release of TGF-β and cytokines like IL-10 and inhibit the release of IFN-γ and IL-12 in the culture supernatant of nodal lymph and spleen suspension of BC-bearing mice compared to control. In addition, there was a low expression of CD80 and CD86 on DCs, which indicates a low maturation process.

Conclusion:

According to the findings, the tumor microenvironment may have been responsible for preventing the maturation of DCs. This, in turn, weakened the immune response and facilitated the ability of the tumor to proliferate. Furthermore, the tumor microenvironment increased the number of immature DCs by inhibiting their stimulation by overexpression of TGF-β-produced by regulatory T lymphocytes and stimulation of tumor cells. In addition, the tumor microenvironment stimulated the secretion of cytokines such as IL-10, and CD4 and decreased the secretion of IFN-γ-and IL-12 in tumor-induced mice cultured LN and spleen.
Dietary Effect of Borage (Borago officinalis) Powder on Growth Performance, Immune Response, and Blood Biochemical Parameters in Common Carp (Cyprinus carpio) Juvenile
Authors: Cheraghi Parisa , Mohammadiazarm Hamid , Maniat Milad
Published: January 2023

In this study, the effect of borage (Borago officinalis) powder on juveniles of common carp (Cyprinus carpio) were investigated. The diets contained control (0), 0.5%, 1.5%, and 2.5% of borage powder. The fish with the initial average weight of 8.40 ± 1.37 were allotted to 12 circular tanks of 300 L capacity at a density of ten fish per each tank and fed to apparent satiety three times a day. The growth performance of the fish showed no significant difference compared to the control group (P > 0.05). By adding 1.5% borage powder to the control diet the mucosal immunity of fish in terms of lysozyme activity (14.26%), total protein (69.64%), immunoglobulin (30.78%), and humoral immunity in term of lysozyme activity (9.7%), complement components C3 (8.27%), C4 (21.64%), and total protein (9.33%) were increased significantly (P < 0.05). A total number of red blood cell (12.39%), mean corpuscular volume (MCV, 8.99%), mean corpuscular hemoglobin (MCH, 10.22%), and hemoglobin (2.69%) showed a significant increase in the fish fed supplemented diet with 1.5% borage powder compared to the control (P < 0.05). The results showed supplemented diet with 1.5% dietary borage powder induced high immunity and survival rate of juvenile common carp.

Published: January 2023

Cost of fish production can be reduced by replacement of high-priced fishmeal (FM) with insects sourced ingredients. Four months feed experiment was conducted at a fish farm in Baringo County, Kenya to investigate effects of substituting fishmeal (FM) with black soldier fly larvae meal (BSFLM) on survival and growth performance of C. gariepinus under aquaponic system. Three test diets 35% crude protein content (CP) in which FM was substituted by BSFLM at 25%, 50% and 75% were formulated and experimented with commercial diet of 35% CP. Four weeks old C. gariepinus were stocked in 12 tanks at a density of 50 fish/tank and subjected to the diets. Fish were sampled every three weeks; water parameters were sampled weekly and mortality recorded on occurrence. Diet with 50% BSFLM obtained better FCR for formulated diets with no significance (P<0.05) for FCR and survival. Weight gain of control diet (97.07 g) was significant (P<0.05) compared to formulated diets 64.09g, 69.78g and 67.77g for 75%, 50% and 25% of BSFL replacement respectively. Growth performance and survival demonstrated that BSFLM has potential to substitute FM up to 75%. The fish productivity can be improved and feed cost reduced by incorporating fully defatted BSFLM with CP higher than 25.3% used for the diets.

Published: January 2023

The present study was conducted to evaluate the effect of different dietary protein levels on digestive enzyme activities, nutrient assimilation as well as growth performance in striped catfish (Pangasianodon hypophthalmus). Fish were fed with four semi-purified formulated diets with increasing levels of protein: 30% (CP30), 35% (CP35), 40% (CP40) and 45% (CP45) for 12 weeks. At the end of the feed trial, the highest weight gain (29.88 g fish-1), specific growth rate (3.58%) and lower feed conversion ratio (1.91) were observed in fish that were fed with a 40% protein diet while CP30 treatment group had the poorest growth performance indicators (P<0.05). Proximate analysis revealed that fish fed with either CP40 (18.50%) or CP45 (19.33%) diets had the highest protein content in comparison to that fed CP30 (17.13%) and CP35 (17.00%) diets. Similarly, the highest body lipid content was CP35 (4.20%) treatment group and the lowest in CP40 (3.83%). The amino acid in the harvested fillets was also significantly higher (P<0.05) in both CP40 and CP45 dietary treatments. The increasing dietary protein level also elevated both protease and amylase activity, while lipase activity significantly decreased (P<0.05). The study revealed that a 40 % protein level diet produced from regional ingredients in the Middle East had yielded optimal growth performance and higher muscle quality in striped catfish.

Published: January 2023

This study investigated the potentialities of rural sports (with emphasis on the popular yuletide sporting events) with regard to sports tourism development in rural communities of Southeast Nigeria. Four paradigms (perceptions, arrivals, impacts and safety issues) were used for this investigation. However, ten rural communities with a history of such events were conveniently sampled from the five states of the region in Nigeria. Yaro Yemene’s formula aided the sampling of 400 respondents for the distribution of semi-structured questionnaires. In addition, cluster and purposive sampling techniques were further used to select forty key informants for the study. Chi Square and descriptive statistics were used in the analysis of data. The result of the study shows that this yuletide sporting event has potentialities to enhance sports tourism development in the rural areas judging from the information from the four paradigms. The implication of the study is that it has opened another self-development option for rural communities in Nigeria. This study has contributed to responsive rural development in traditional African communities through the opportunities of local sports.
Assessment of Co-Joint Factors Influence on Guests' Choice of Fine Dining
Restaurants in Kenya

Published: January 2023

There is limited data and studies that have assessed the co-joint influence of social media applications, social demographic, and individual factors on guests' choice of fine dining restaurants. Previous studies have shown increased use of social media applications by consumers and subsequently influenced decision-making. Thus, need for innovation to meet consumer expectations. A mixed-method approach was used to assess co-joint factors of influence on guests' choice of fine dining restaurants in Kenya. Questionnaires were used to collect quantitative data from purposively selected guests. Data were subsequently analyzed and presented in the form of descriptive and inferential statistics. Testing of the null hypothesis was also conducted. The calculated value of R-squared implies that the remaining variations or determinants in the choice of fine dining restaurants are attributed to factors other than the composite variable. Besides the significant influence of social media applications, there are other factors attributable to guests' selection process. This study contributes to the theory of consumer behaviour in the larger hospitality and tourism industry. The study further reveals new dimensions on the selection of restaurants' products and services. In this direction, managers and owners of restaurants need to embrace more technology in their businesses.

Authors: Dirdal Hildegunn , Hasund Ingrid Kristine , Danbolt Drange Eli-Marie , Thue Vold Eva , Berg Elin Maria
Published: January 2023

This article describes the design and construction of the Tracking Written Learner Language (TRAWL) Corpus. The corpus combines several features that are all rare for learner corpora: it is longitudinal, following individual pupils over several years; it has data from young learners from school years 5 to 13 (ages 10–18); it is multilingual, containing learners’ texts in several L3s (French, German and Spanish), L2 English and L1 Norwegian; and it includes teacher comments on a number of the texts. In addition, some of the texts exist in both a first and a second revised version, all tied to a rich set of meta-data. Not only does such a corpus offer new possibilities for research on language acquisition in general; it can also be used to provide valuable insights for teachers, teacher training and policymaking within the national context of Norway. In this article, we describe the design of the TRAWL Corpus and outline its uses and benefits for the research community. We also describe the compilation process in the hope that it may inspire and enable others to build similar corpora for their own national contexts.

Published: January 2023

The purpose of the research is financial and legal protection of land from being contaminated with hazardous substances (wastes) as a component of regional environmental policy. Main content. It is known that land contamination by industrial enterprises, through irrational use of agrochemicals and chemical plant protection agents lead to the accumulation of toxins, including heavy metals, pesticides, oil products, radionuclides. Therefore, one of the important factors of improving the legal protection of land, including protection from being contaminated with hazardous substances in Ukraine, consists in taking into account positive experience of those post-Soviet states that have a practical orientation in terms of legislation and achievements in law enforcement activities related to land protection. Methodology: The methodological basis of the research is presented as comparative-legal and systematic analysis, formal-legal method, interpretation method, hermeneutic method as well as methods of analysis and synthesis. Conclusions. The institution of legal land ownership in the post-Soviet Baltic states (Estonia, Lithuania, Latvia) and Georgia has been disclosed in detail. Justifiably, contamination is dangerous not only for life and health, but also for land resources in general.

In this regard, the object of the study were security threats that determine stability in Ukraine and Pakistan. The authors used the method of comparative analysis to draw parallels between the security of Ukraine and Pakistan and identify possible ways to improve it. It is concluded that, both Ukraine and Pakistan are quite geopolitically distant, have different histories and state-building processes, but are affected by traditional and "non-traditional" security threats. Definitely, the main unifying factor for the states is the antagonistic or "enemy" state - India for Pakistan and Russia for Ukraine, which becomes a catalyst for the formation of national identity and unity of society. The conflicts in Pakistan (Kashmir, Baluchistan and Pashtunistan) and Ukraine (war in Donbass, illegal annexation of Crimea by the Russian Federation) have had common consequences and mechanisms for overcoming them, which are implemented in the context of the internal and state policy of both Kiev and Islamabad.
