How are the classification of students’ mathematical connections in solving non-routine problems?
Authors: Kholid Muhammad Noor , Dewi Rosita
Published: June 2024

Background: Mathematics is not just a science for its own sake; it is a science that proves to be useful for most other sciences. Mathematical connections play a crucial role in helping students develop a deeper understanding and enhance their thinking about mathematics. These connections represent relationships between different mathematical ideas, between mathematics and other subjects, and between mathematics and everyday life.Aim: This study aims to classify students' mathematical connection abilities when solving non-routine mathematical problems.Method: This research employs a qualitative approach using descriptive and exploratory methods. The study involved 23 students who exhibited mathematical connection skills in problem-solving. Data collection methods included tests, observations, and interviews. The data analysis process consisted of two main stages: data reduction and data presentation. To ensure data validation, the triangulation method was used by comparing the results from the subject tests (answer sheets), observations, and interviews.Results: The findings of this study revealed three distinct classifications of students’ mathematical connections when solving non-routine problems: 1) Patterns; 2) Variables; and 3) ArgumentsConclusion: The implications of these findings suggest that teachers need to be aware of the different classifications of students' mathematical connections. This awareness will enable them to implement mathematics learning strategies that cater to the diverse mathematical connection classifications found in their classrooms. For instance, teachers can utilize different mathematics learning media tailored to students’ learning styles, such as mind, incubation, and visual learning. By doing so, students can better optimize their mathematical connections and achieve improved outcomes in their mathematics learning.
Developing CEFR-Based Digital Literacy Resources for Multisensory English Learning
Authors: Alfiani Dewina , Khomarudin Khomarudin
Published: June 2024

Indonesia has the latest curriculum, namely the independent curriculum, whose learning is holistic and based on the CEFR level.  However, in practice, the learning and teaching still uses traditional pedagogy that relies on the left brain and focuses only on grammar (linguistics).  This fact is supported by evidence of a decline in the English proficiency index (EPI) in 2022 which shows that Indonesia is at a low level (ranked 81 out of 111 countries). In his latest research, Sudimantara (2021) develops a new pedagogy (Multisensorial Load Reduction Strategies) that activates the nonverbal components of language (rhythm, intonation, movement, emotion, and aesthetics). Another research by A,-P Lian & Cai (2021) also introduces a Verbotonal Approach which emphasizes prosodic information (intonation and rhythm) to rearrange the learner’s perception of the language being learned thereby facilitating language learning. In line with previous research, this research provides an innovative development of digital literacy resources for multisensory English learning based on CEFR. This research uses qualitative development with R&D (Research and Development) design with the research step to be carried out (Analyzing, design, developing, and Evaluation). The results show that these digital literacy resources can be applied by teachers for student learning. This research is expected that digital literacy can be further developed for multisensory learning which is beneficial for language learning.Keywords: CEFR-Based Learning, Digital Resources, Multisensory
Modern problems of the Russian Federation fishing industry enterprises development
Authors: Demchuk Oleg Vladimirovich
Published: June 2024

The fishing industry at the present stage of the development of economic relations in Russia belongs to strategically important areas of ensuring the food security of the state. The sanctions policy pursued by a number of countries against Russia has affected, among other things, the fishing industry. Meeting the needs of the country's population in high-quality fish and seafood products is one of the main goals of the production and economic activities of fisheries enterprises. The Russian Federation has huge water resources, which objectively determines the presence of a large number of enterprises related to the fishing industry. The Russian Federation has huge water resources, which objectively determines the presence of a large number of enterprises related to the fishing industry. Despite this, on the one hand, there is no wide range of products on the fish and seafood market, and on the other hand, prices for available fish and seafood are growing much faster than prices for meat, vegetables and fruits. In recent years, there has been a constant situation in which the volume of fish and seafood production by domestic mining enterprises tends to increase, and the average per capita consumption of fish by the population of the country is constantly falling. At the same time, the fisheries complex has a huge potential for its successful development both in the present and in the future. There is an objective need to identify, classify and evaluate the influence of factors that ensure these trends, as well as further research aimed at reversing the identified trends towards expanding and more fully saturating the domestic market with fish products. Conclusions are drawn about the need to develop a set of measures to improve the efficiency of the final results of production and economic activities of enterprises of the fishing industry.

Authors: Cherniaev Evgeniy Vasilevich
Published: June 2024

The analysis of the causes of problems in the development of the electronic and radioelectronic industry in Russia caused by deficiencies in regulatory documents for planning business activities of enterprises and their consequences is carried out. The possible causes of problems of inefficient use of resources allocated by the state and business for the restoration of the electronic and radioelectronic industry in Russia are considered. It is indicated that the problems of low return on investment, disruptions in the timing of investment development and product deliveries to customers, exceeding current cost estimates over planned ones may be caused by deficiencies in regulatory documents for planning business activities of enterprises. The consequences of these problems in planning the activities of enterprises in the industry under study are revealed, which affect the pace and quality of the following tasks: import substitution, increasing technological and innovative potential, increasing the role of the Central Bank of the Russian Federation in lending to the real sector of the economy, including subsidizing government orders. A list is provided and a summary of the main strategic planning documents for the electronic and radioelectronic industry is considered. An overview of the main shortcomings and shortcomings of the designated documents has been compiled. The example of specialized enterprises of the Samara region is considered, which indicates that currently the results of achieving technological self-sufficiency in the production of complex products have not been achieved, and in some cases an acute dependence on foreign supplies has been revealed. Recommendations are given to reduce the impact of the identified problems arising during the restoration of the electronic and radioelectronic industry, in terms of improving the legislative framework.

In this paper, we deal with the resolution of the simplicial cone constrained convex quadratic optimization (abbreviated SCQO). It is known that the optimality conditions of SCQO is only a standard linear complementarity problem (LCP). Under a suitable condition, the solution of LCP is equivalent to find the solution of an absolute value equations AVE. For its numerical solution, we propose an efficient two-steps fixed point iterative method for solving the AVE. Moreover, we show that this method converges globally linear to the unique solution of the AVE and which is in turn an optimal solution of SCQO. Some numerical results are reported to demonstrate the efficiency of the proposed algorithm.
Keywords: Quadratic programming, simplicial cones, absolute value equations, linear complementarity problem, Picard’s fixed point iterative method.
Palatability and Suitability of the Ulmaceae for Spongy Moth Larval Development (Lepidoptera: Lymantriidae)
Authors: Miller Fredric , Ware George
Published: June 2024

Fifty-nine Ulmus taxa, varieties, and cultivars and six Zelkova taxa and cultivars were evaluated in no-choice (NC) and multiple-choice (MC) laboratory feeding bioassays for suitability and preference for spongy moth larvae (Lymantria dispar L.). Ulmus ‘Morton Stalwart’-CommendationTM, U. ‘Morton Red Tip’-Danada CharmTM, ‘Frontier’, ‘Homestead’, ‘Regal’, and U. elliptica were found to be the most suitable (suitability ratios of > 0.90). Ulmus gausennii, and U. carpinifolia were the least suitable (suitability ratio < 0.5). The remaining Ulmus and Zelkova taxa were either unsuitable (i.e. larvae failed to pupate) or were moderately suitable (suitability ratios 0.54 to 0.86). Dry frass weight was a moderate predictor of larval longevity. Feeding preference was moderately correlated with larval longevity and percent larval survival. Leaf thickness and toughness does not appear to affect larval survival, pupal fresh weight, or frass production. Asian elm leaves possess both glandular and straight trichomes but they did not affect larval suitability. Hybridization significantly affected host susceptibility and appears to contribute to an “U. pumila and U. carpinifolia factor” for host preference, susceptibility, and suitability. There appears to be a rich pool of Ulmus and Zelkova taxa for potential use in future tree breeding programs.

Beneficial element (vanadium) improves Zinnia elegans flowers
Authors: Hernández-Quezada Evelyn , García-Gaytán Víctor
Published: June 2024

Our study evaluated the effect of vanadium (V) on the behavior of Zinnia elegans “double variegated”. In this experiment, Zinnia plants grown in a greenhouse were fed with a nutrient solution and two concentrations of vanadium (0, 6, and 10 μm) applied four times during the experiment. The V at its levels of 6 µm and 10 µm increased plant length, number of inflorescences and fresh weight. We observed that during the development and appearance of flower buds, and flowering were earlier with the addition of 6 µm and 10 µm. During harvest the changes in size and shape were homogeneous with the control treatment. With the addition of 6 µm, flowers of different sizes were induced, with non-uniform petals, but with different shades of color. With 10 µm the shape of the petals, the distance between them and changes in the shades of the flowers were modified. The postharvest life for the flowers of the control treatment was shorter (15 days), the petals, anthers and floral disc at this time were observed in a poor condition. While 6 µm and 10 µm had a longer postharvest life (20 days), the flowers had a good presentation, their colors were more intense compared to the harvest stage. The application of this beneficial element contributed to the development and flowering of Zinnia in the greenhouse. It is suggested that future research be carried out on the accumulation and/or concentration of vanadium in the different stages of growth or its effect on the concentration of other nutrients.

Família multiespécie
Authors: Santos Rayanne Quinterno dos , Ningeliski Adriane de Oliveira
Published: June 2024

O presente artigo, visa abordar as modificações sobre o conceito de família presentes na história, bem como os tipos familiares decorrentes destes, tendo como fulcro a afetividade em sua formação. Também contempla em si, as mudanças em torno do Direito Animal, suas concepções doutrinárias e legislativas, principalmente, a visão do animal não humano como ser senciente, e não como mero objeto semovente. A partir do estudo desses dois ramos do Direito, tem por objeto central, entender a Família Multiespécie como tipo familiar a ser reconhecido e legislado pelo ordenamento, tratando e prevendo soluções a situações que possam ocorrer, vislumbrando suas características únicas, da relação afetiva entre diferentes espécies como família. O método de abordagem utilizado é o dedutivo, pois a partir de estudos e pesquisas realizadas na área do Direito, com doutrinas e jurisprudência conclui-se que o reconhecimento da Família Multiespécie, é fato existente, mas não efetivamente legislado, promovendo dificuldades sociais a quem se enquadra no tipo familiar e não pode recorrer efetivamente a justiça por falta de previsão legal.
Initial screening for dental abnormalities identified by labial and buccal photographs in dogs and cats
Authors: Ryu Yeonje , Kim Se Eun , Huh Eun A. , Park Sungjun , Kim Sunghoon , Kim Hyunjung , Seo Kangmoon
Published: June 2024

OBJECTIVE

To evaluate the dental abnormalities by visually assessing the labial and buccal photographs in dogs and cats and analyze their prevalence based on age and breed.

ANIMALS

1,096 client-owned dogs and 775 client-owned cats.

METHODS

Data were collected from patients who visited 26 private veterinary clinics from January to December 2022. Each animal was evaluated through dental photographs taken from the labial and buccal sides. Correlations between the prevalence of the identified dental abnormalities and age, craniofacial type, and breed, were analyzed.

RESULTS

Calculus, discoloration, epulis, fractured teeth, gingival recession, gingivitis, malocclusion, missing teeth, and persistent deciduous teeth could be identified by analyzing the dental photographs in both dogs and cats. Enamel defects in dogs and tooth resorption in cats could be identified. Brachycephalic dogs had a significantly higher prevalence of malocclusion (OR, 1.93; 95% CI, 1.36 to 2.75) and missing teeth (OR, 3.63; 95% CI, 2.71 to 4.91) compared to nonbrachycephalic dogs. Brachycephalic cats had a significantly higher prevalence of fractured teeth (OR, 1.95; 95% CI, 1.24 to 3.04) and a lower prevalence of gingival recession (OR, 0.30; 95% CI, 0.15 to 0.55) compared to nonbrachycephalic cats. Calculus, persistent deciduous teeth, and possibly gingivitis could be identified in dogs and cats by analyzing labial and buccal photographs. The assessment of some dental abnormalities such as fractured teeth, missing teeth, and tooth resorption can be limited without a complete dental examination under anesthesia.

CLINICAL RELEVANCE

Although the assessment of dental conditions may be underestimated, the data on the prevalence of the dental abnormalities evaluated through the photographs could be utilized for screening dental diseases.
Nasally delivered chitosan-coated poly(lactide-co-glycolide) encapsulating honeybee venom enhances T helper 1–related immunity against Salmonella Typhimurium infection in pigs
Authors: Lee Jina , Jung Bock-Gie , Lee Bong-Joo
Published: June 2024

OBJECTIVE

Salmonella Typhimurium is a significant zoonotic concern for human food poisoning and a substantial economic burden in the swine industry. We previously reported that nasally delivered chitosan-coated poly(lactide-co-glycolide) (PLGA) encapsulating honeybee venom (CP-HBV) could enhance CD4+ T helper 1 (Th1)-related immune responses in healthy pigs. Building upon these findings, the current study aimed to investigate the protective immune enhancement by nasally delivered CP-HBV in pigs challenged with S Typhimurium.

ANIMALS

36 healthy, 4-week-old, female, Landrace X Yorkshire X Duroc pigs.

METHODS

36 pigs were allocated into 3 groups: CP-HBV (n = 16), control (n = 16), and healthy baseline control (n = 4). CP-HBV and control groups were challenged with S Typhimurium 7 days post-treatment. Pigs from the healthy control group were sacrificed at 0 days postinfection (DPI), and 4 pigs from each of the control and CP-HBV groups were sacrificed at 1, 2, 4, and 7 DPI. Salmonella shedding, immune cell frequencies, cytokines, and transcriptional factor expression levels were measured.

RESULTS

The CP-HBV group exhibited lower bacterial shedding and an enhanced Th1-related immune response characterized by an upregulation of CD4+ T cells and CD4+ Interferon-γ+ T cells, accompanied by increased expression of Th1-related cytokines and reduced expression of regulatory T cells and immunosuppressive cytokines compared to the control group.

CLINICAL RELEVANCE

CP-HBV is a promising strategy for controlling Salmonella infections in pigs and improving public health.
Subcutaneous amikacin administration in red-eared sliders (Trachemys scripta elegans) produces prolonged detectable plasma concentrations without biochemistry evidence of impaired renal function
Authors: Hiebert Kara , Knych Heather , Hawkins Shawna
Published: June 2024

OBJECTIVE

To establish pilot data on the plasma concentrations of SC amikacin at 2 doses in red-eared sliders and evaluate concurrent plasma biochemistry parameters.

ANIMALS

8 adult red-eared sliders (Trachemys scripta elegans).

METHODS

Amikacin was administered SC at target doses of 5 and 10 mg/kg with a 3-week washout period. Blood samples were collected at 0, 24, 48, 72, and 96 hours postadministration. Plasma amikacin concentrations were quantified using liquid chromatography tandem mass spectrometry. Plasma biochemistry analyses were performed before amikacin administration, 1 week post 5-mg/kg administration, and 1 week post 10-mg/kg administration.

RESULTS

Mean maximum amikacin plasma concentrations were recorded 24 hours after 5-mg/kg and 10-mg/kg dosing and were 17.5 ± 2.32 µg/mL and 23.6 ± 2.92 µg/mL, respectively. Mean plasma concentrations after 5-mg/kg dosing steadily decreased to 9.1 ± 0.92 µg/mL by 96 hours postadministration. Amikacin remained detectable in all plasma samples 3 weeks post 5-mg/kg dosing with a mean plasma concentration of 1.04 ± 0.22 µg/mL. Mean plasma concentrations after 10-mg/kg dosing did not decrease over the 96-hour study period. There were no clinically relevant changes in biochemistry parameters.

CLINICAL RELEVANCE

Amikacin persists at detectable plasma levels for at least 3 weeks after SC administration of a 5-mg/kg dose in red-eared sliders, which has not previously been reported in any species. No biochemistry changes consistent with renal toxicity occurred after either dose. Use caution with repeated amikacin dosing in this species until further studies can better characterize cumulative amikacin pharmacokinetics and toxic threshold.
Controls on the Termination of Cretaceous Oceanic Anoxic Event 2 in the Tarfaya Basin, Morocco
Authors: Krewer Chiara , Poulton Simon W. , Newton Robert J. , März Christian , Mills Benjamin J. W. , Wagner Thomas
Published: June 2024

Oceanic Anoxic Event 2 (OAE2) has been the focus of considerable research, but biogeochemical dynamics during the recovery from the carbon cycle disturbance largely remain unknown. Here, we present a high-resolution reconstruction of water column redox and nutrient cycling across the final stages of OAE2, in order to assess controls on the termination of widespread ocean anoxia. We focus on calcareous black shales deposited on a subtropical shelf at Tarfaya, Morocco, representing a location prone to water column anoxia beyond the temporal extent of the OAE itself. Our multi-proxy approach combining iron-sulfur systematics with redox-sensitive trace metal (U and Mo) concentrations documents persistent anoxia, with cyclic fluctuations between weakly euxinic (or possibly ferruginous) conditions and more intense euxinia. During the end of the carbon isotope plateau phase, elemental weathering ratios indicate muted variability in chemical weathering intensity, although fluctuating redox conditions may have been driven by changes in continental weathering inputs of sulfate and reactive iron. By contrast, during the recovery phase, changes in chemical weathering intensity appear to have exerted a strong control on redox fluctuations. Overall, the recovery phase documents progressively less reducing conditions and less intense chemical weathering, which resulted in decreased P recycling and intervals of P drawdown, as indicated by P phase partitioning results. These trends were interrupted by the Holywell Event, during which more intense euxinia and enhanced P recycling transiently returned during an interval of particularly low chemical weathering. Nevertheless, the general trend towards lower P bioavailability in the water column, due to both sequestration of P in the sediments and a likely progressive decrease in P supply via continental weathering, appears to have exerted a major control on the recovery from oceanic anoxia in this shelf setting, and potentially on a global scale.
A Detailed Examination of 8th Grade Students’ Mathematical Reasoning Process
Authors: Zengin Şeyda , Erdem Emrullah
Published: June 2024

Introduction:

This study aims to reveal the mathematical reasoning process of 8th-grade students and the reasoning indicators they use in this process.

Methods:

The study was carried out in line with the data obtained from the Mathematical Reasoning Test (MRT) administered to 292 8th-grade students.

Results:

The mathematical reasoning performances of the participants were generally at low and medium levels. Evidence was found that students used reasoning indicators such as “… for/because of…, /therefore/so/thus…”, “if … then…”, “because…”, “should be/should be...” and “equal...” when reasoning.

Discussion:

It is important that when evaluating the solutions to questions that require mathematical reasoning, students must be interviewed and confirmed how they reached those solutions.

Limitations:

The limitations of the research are, firstly, that it is limited to 8th graders, and secondly, that students will get bored if the number of questions in the MRT is high.

Conclusions:

Students must be asked to justify their reasoning while solving problems that require mathematical reasoning.
The Need for Academic Writing in Albania
Authors: Skendaj Klodjana
Published: June 2024

Introduction:

This research analyzes the importance of academic writing in Albania and suggests introducing it as a mandatory course in all fields of study. The study aims to identify students' perceptions of academic writing and the importance of clear structure and guidelines in academic writing templates. The research collected data through 253 online questionnaires from students of private and public HEIs (Higher Education Institutions) in Albania, revealing that students lacked adequate skills in primary writing forms and were unaware of the steps required to use resources.

Methods:

253 Albanian university students participated in a study on academic writing abilities and methods. The study used a structured questionnaire with 23 closed-ended questions related to statements relevant to the concepts provided by the Literature Review on the issues of writing skills, methodology, and the required steps of academic writing.

Results:

The study found that over half of the students surveyed did not study academic writing, which was mainly offered as an elective course for the undergraduate level. Less than half of the students confirmed that their universities offered a template for them to guide themselves through the studying process. The research also found a connection between the lack of academic writing in the curricula and academic integrity.

Discussion:

The Ministry of Education and HEIs should provide theoretical and methodological guidelines for designing academic writing courses in Albanian. Academic writing programs in Albanian and English should be offered to faculty members and researchers. Academic Writing should be mandatory for every study program, collaborating with disciplinary professors and linguistics to improve the existing curricula and creating opportunities for students to express their critical thinking through writing skills.

Limitations:

Due to the COVID-19 pandemic, this research faced limitations in accessing the syllabi of some faculties and restricted student gatherings. Therefore, the questionnaire was delivered online, and the results presented in the paper refer to the respondents' self-regulation while answering online.

Conclusions:

The survey revealed that students from public and non-public higher education institutions lack basic writing skills, prefer internet guidance over professor's assistance, struggle with paraphrasing, summarizing, and referencing, and lack academic integrity. However, students showed a high interest in academic writing as a mandatory course in higher education institutions.
Exploring Entrepreneurial Intention for Sustainable Development: a Study of University Students in Kolea, Algeria
Authors: Meslem Amina , Bouchetara Mehdi , Gahlam Nadia , Djennadi Lydia , Belali Mounir
Published: June 2024

Research purpose

Entrepreneurship's evolving role now extends beyond economic realms to encompass broader societal and environmental imperatives. Sustainable entrepreneurship emerges as a linchpin in addressing contemporary challenges, offering innovative solutions that harmonize economic resilience with environmental and social objectives. Yet, the determinants underpinning individuals' intentions towards sustainable entrepreneurship, particularly within the Algerian context, remain underexplored. Keeping this into consideration, our research endeavours to identify the motivational factors influencing the decision to engage in sustainable entrepreneurial activities among students at the Kolea University Pole.

Design / Methodology / Approach

Drawing on a quantitative approach, data from 370 student responses were analysed using linear regression analysis.

Findings

The findings reveal the significant influence of both internal and external determinants on entrepreneurial intention for sustainable development among students. Internally, factors such as perceived entrepreneurial feasibility, perceived behavioural control, and attitudes towards sustainability emerged as key drivers of entrepreneurial intention towards sustainability. Students with a strong inclination towards sustainability exhibited a heightened intention to engage in entrepreneurial activities aligned with sustainable development goals. Externally, sociological factors and social networks were found to exert a significant positive influence on sustainable entrepreneurship intention. This underscores the importance of familial, educational, and societal support structures in fostering an entrepreneurial mindset among students, shedding light on the role of information and communication technologies in shaping this intention. Yet, the study also highlights a concerning lack of awareness among students regarding the role of entrepreneurship in addressing environmental challenges underscoring the need for educational interventions aimed at cultivating an environmental ethos among students.

Originality/Value/Practical Implications

This study contributes to the discourse on sustainable entrepreneurship in developing countries, particularly in Algeria, by elucidating the factors influencing entrepreneurial intention among students. The findings underscore the importance of both internal and external determinants in shaping students' entrepreneurial aspirations, with implications for educational policy and practice.
Does Economic Complexity Influence Carbon Emissions? Evidence from Next Eleven Countries
Authors: Osinubi Tolulope Temilola
Published: June 2024

Research Purpose

The study examines the effect of economic complexity on carbon dioxide emissions in the Next 11 countries with the view to validate or refute the economic complexity-Kuznets curve (EcKC) between 1995 and 2019. The Next 11 countries include Bangladesh, Egypt, Indonesia, Iran, Mexico, Nigeria, Pakistan, Philippines, South Korea, Turkey, and Vietnam.

Design/Methodology/Approach

Two econometric methods, correlated Panel standard error (PCSE) and feasible generalized least squares (FGLS) estimating techniques, are used to achieve the objectives of the study.

Findings

The estimates from the FGLS approach are consistent with that of the PCSE approach. The results from both techniques show that economic complexity increases carbon emissions in the Next 11 countries. Also, from the EcKC, the study invalidates the hypothesis and supports a positive monotonic linear relationship between economic complexity and carbon emissions, which also means the “pollution haven hypothesis”.

Originality/Value/Practical Implications

The study examines whether the environmental Kuznets curve (EKC) in the Next 11 countries is valid or not. To do this, the current study is different from earlier studies in that it uses economic complexity—that is, the economic complexity-Kuznets Curve (ECKC)—instead of GDP. This is explained by the fact that environmental issues should involve the development of more advanced commodities rather than just raising an economy's GDP productivity. And most of the countries in the Next 11 countries are currently shifting their economies to produce more complex goods.

Findings.

Advertising employees have high emotional exhaustion, moderate levels of depersonalization or cynicism, and high levels of personal achievement reduction. The highest indicators of general personality traits are as follows: openness to experience, conscientiousness, and honesty - humility, while lower indicators are for extroversion, neuroticism, and agreeableness. Emotional exhaustion has a strong positive correlation with neuroticism and a negative correlation with extroversion; depersonalization has a positive correlation with neuroticism, a positive correlation with agreeableness and a negative correlation with extroversion. Decreased achievement or work efficiency has a strong negative correlation with neuroticism, a strong positive correlation with extroversion, and a positive correlation with openness to experience. Burnout dimensions also have very close positive and negative correlations with the sub-traits. There are statistically significant regression models between professional burnout scales and sub-traits: depressiveness and sociability have the greatest impact on emotional exhaustion; the greatest impact on depersonalisation is for depressiveness; joyfulness; friendliness; the greatest impact on changes in performance is for stress intolerance; joyfulness; creativity.

Practical implications.

With at least 50% of advertising employees experiencing high levels of burnout, it is recommended to organise individual and Team Supervision sessions to prevent burnout and identify the triggering factors in a specific organization. This format ensures that both employees and managers are equally accountable for the outcome and through a focused process promotes overall employee engagement, problem-solving, conflict resolution, understanding of diversity, empathy, and role clarity. No less important, the knowledge of the most common personal traits of Advertising Industries employees will help company managers to make more informed hiring decisions.

The strike embarked upon by the Academic Staff Union of Universities (ASUU) in Nigeria has significant impact on different stakeholders. Hence, this study investigated the implication of ASUU strike on students in Olabisi Onabanjo University, Ago-Iwoye, Ogun State, by examining the lifestyle of students during ASUU strike; its effects; and the coping strategies employed by the students during the strike. This study was conducted among undergraduates of Olabisi Onabanjo University, Ago-Iwoye. Cross-sectional survey design was used and 132 undergraduates were sampled using convenience sampling. Primary data were collected through the questionnaire, and the data were analysed using descriptive statistics such as simple percentage and frequency count.

Results showed that more students engaged in actively participating in social media and praying for the strike to be over, relaxation, and learning of skills while gardening, getting a certification course or interim job were the least engaged by students during the ASUU strike. The results above indicated that boredom was the highest effect of ASUU on students’ lifestyle, followed by worry and by anxiety while mental issues was the least felt consequence of ASUU strike by students. The study also revealed that the students employed some coping mechanism such as praying for an end to the strike, social media usage, learning a skill and even sleeping to mitigate the implications of ASUU strike. The study then concluded that the disruption of academic activities during the ASUU strike made students engage in different lifestyles while overcoming its effects by using coping strategies.

Introduction

Rabies is endemic in Europe and red foxes are the vector and reservoir of the rabies virus (RABV). Based on classification established in the early 1990s, four variants of the rabies virus have been distinguished in Europe. Rabies broke out in January 2021 in the Mazowieckie voivodeship in central north-eastern Poland. The virus spread rapidly, reaching the Świętokrzyskie voivodeship in the central southern part and the Lubelskie voivodeship in the eastern part in the next months. Nine rabies cases were reported in the Podkarpackie voivodeship in south-eastern Poland between 2021 and 2023, mainly in red foxes but also in dogs and wildcat. The aim of the study was the identification of RABV variants in wildlife and domestic animals in Poland between 2021 and 2023.

Material and Methods

The study involved 157 animal brains tested positive for rabies using a fluorescent antibody test. From 10% w/v brain homogenates, RNA was isolated and full-length RABV genomes were high-throughput sequenced with an RABV-enriched approach. Complete genomes of RABV isolates were phylogenetically analysed and the variants were estimated.

Results

Molecular and phylogenetic studies revealed 147 (93.6%) of the RABV strains out of 157 which had rapidly spread in the wildlife of the Mazowieckie, Świętokrzyskie and Lubelskie voivodeships to be Central European strains. Nine RABVs (5.7%) detected in foxes, a wildcat and a dog in the Podkarpackie voivodeship were identified as North-Eastern European. A vaccine-induced rabies case was detected in a red fox in the Lubelskie voivodeship in May 2023.

Conclusion

Central European and North-Eastern European RABVs were circulating in Poland between 2021 and 2023.
Exploring Community Trust and Attitudes Towards COVID-19 Vaccination in Banda Aceh, Indonesia
Authors: Husna Cut , Charyasti Desvi , Darliana Devi
Published: June 2024

To mitigate COVID-19 infections and safeguard the community against infection risks, the Indonesian government initiated a national COVID-19 vaccination program. It was observed that the community exhibited a mix of acceptance and reluctance toward the vaccination program due to varying information disseminated through multiple media sources, particularly concerning the issue of halal vaccines and their potential adverse effects. The decision to undergo COVID-19 vaccination is closely tied to the community's confidence in the vaccine's efficacy. Vaccine hesitancy poses a significant obstacle in the battle against the COVID-19 pandemic. Several factors contributing to the community's trust in the vaccine encompass shared norms and values, willingness to endorse, and perceived efficacy. The objective of this study was to identify the relationship between the community's trust in the effectiveness of the COVID-19 vaccine and their attitudes toward receiving vaccinations in the region of Banda Aceh. To achieve this, a correlational study with a cross-sectional design was conducted. The study's sample consisted of the community residing in the Kuta Alam sub-district of Banda Aceh, totalling 266 participants. Data collection was facilitated through the administration of the "Community Trust in the COVID-19 Vaccine Questionnaire" and the "Community Attitudes Toward Receiving Vaccinations Questionnaire." The collected data underwent analysis utilizing Spearman's rank test. The study's findings demonstrated a significant relationship between the community's trust in the effectiveness of the COVID-19 vaccine (p = 0.000) and various dimensions, including shared norms and values (p = 0.000), willingness to endorse (p = 0.000), and perceived efficacy (p = 0.000), all of which exhibited a strong correlation with attitudes toward receiving vaccination. Considering these results, it is crucial to involve healthcare professionals and governmental entities in initiatives aimed at promoting the health benefits and efficacy of the COVID-19 vaccine. These efforts should prioritize the enhancement of community trust and the broader acceptance of vaccination.

Physical modelling for tsunami engineering is rather difficult to conduct due to lack of comprehensive and advanced facilities to do so. Large number of simulations of the tsunami impacts were performed numerically. In early 2023, a new advanced tsunami flume facility has been completed at Tsunami and Disaster Mitigation Research Center (TDMRC) of Universitas Syiah Kuala. This flume has 60 m in length, 2.5 m in width, and 1.7 m in height. The flume is also equipped with a number of wave, pressure, and current sensors, Particle Image Velocimetery (PIV) Camera, and a laser bed profiler. Beside of the tsunami generator, this flume is also capable to generate wind-driven waves (with two large wind turbines), regular and irregular waves, and currents. The flume provides new opportunities as well as challenges for tsunami scientists and engineers in Indonesia to collaborate and to perform novel researches in tsunami mitigation. This article is aimed at elucidating technical challenges and opportunities in performing tsunami physical models with the large tsunami flume. we performed a series numerical models using DualSPHysic. The results show that composite beach slopes inside the flume has succesfully mimic shallow coast effects that later deformed the incoming tsunami waves into breaking, bores, and runup. Challenges were identified in absorbing tsunami waves with more than one incoming wave to the observation area. In the future, this facility will be accessible for scientists and engineers to collaborate in tsunami science and engineering researches.
