Higher education institutions have been forced to close campuses and shift towards online learning to prevent the spread of the coronavirus disease (COVID-19). Although the curriculum requires laboratory sessions, fisheries and aquaculture students from a public university in Malaysia shifted their training online, a completely different and unexpected scenario. Due to the virus's rapid spread, the online sessions were not properly prepared by the university but still needs to be performed for the students. As the pandemic forces higher institutions to continue with online learning, understanding the factors influencing students' willingness to continue online learning is crucial for both parties. The study adopted the Technology Continuance Theory and used a purposive sampling method, gathering 294 respondents from the online survey. The study also examined the online learning service quality, conformation, perceived usefulness, perceived ease of use, satisfaction, attitude, performance and fisheries and aquaculture students’ willingness to continue using online learning during the pandemic. Moreover, the study extended the predictive power by introducing the serial mediation of perceived usefulness, perceived ease of use, attitude, performance and satisfaction. Using SmartPLS, the results revealed that all of the hypotheses were supported. Ultimately, the findings provided essential information to understand further the student’s willingness to continue online learning during the pandemic. Furthermore, the results help the top management craft a better strategy and policy on online learning and develop a proper plan to allow students to return to campus life.

In Malaysia, entrepreneurship has been viewed as one of the active economic activities, which could boost the growth of nation and develop the individuals. However, the interest in entrepreneurship among Malaysian students is still low, where most of them prefer to be “job seeker” or “employee” instead of “job creator”. The role of education, generally, has been recognized as a crucial process in developing individuals by providing knowledge and skills. In order to support the creation of new venture among nascent entrepreneur, entrepreneurship education is viewed as crucial element that can encourage this happening which could help to reduce unemployment rate. The impact of social intelligence could be one of the crucial variables to be studied in order to predict the entrepreneurial intention among the students. Hence, this study examined the mediating effect of entrepreneurship motivation on the relationship between the variables. The study found there is a significant mediating effect of motivation on the relationship between education and entrepreneurial intention, but there is no significant mediating effect on the relationship between social intelligence and entrepreneurial intention. This paper discussed the implications and recommendations as well.

This qualitative research study explored the effectiveness of the English Language Textbook, Pulse 2 on the students’ motivation and accommodation to the learning needs based on Gardner’s Motivation Theory. 6 selected participants from rural and urban schools were involved and interviewed purposely. Research findings indicated that English school teachers and students were having difficulties to use the textbook due to requirement of higher-order thinking skills (HOTS) for teachers and students, having loaded Western content and context in the syllabus, and insufficient technology provided in urban and rural schools impending smooth teaching and learning. This research is significant to the Malaysian Ministry of Education to find an alternative textbook to fulfil the gaps in developing motivation to learn English language among Malaysian students. The research findings also recommend that Pulse 2 textbook should be modified according to students’ need and interest to suit Malaysian's contexts.

Published: August 2023

The factors influencing the purchase intention (PI) towards Chinese museum cultural and creative products (MCCP) were investigated. A structural equation model that considered the specific MCCP characteristics was used. The transmission mechanism of consumers’ formation of MCCP PI was explored using antecedent variables (stimuli: perceived enjoyment [PE], perceived quality [PQ], perceived value [PV], and perceived culture [PC] and consumer-perceived normative factors: subjective norms [SN] and perceived behavioural control [PBC]); mediating variables (consumers’ cognitive and emotional states: attitude); outcome variable (response: PI). Confirmatory factor analysis and reliability, validity, and structural equation analyses of the model data were performed with SPSS 25.0 and AMOS 26.0. The results demonstrated that PC and PV positively significantly influenced PI. The PE, PV, and PC positively significantly influenced purchase attitudes (AT) among MCCP consumers. The most influential factor was PE, while PQ did not significantly influence PI and AT. The PBC, SN, and AT positively significantly affected PI. Meanwhile, PBC did not affect AT significantly. Consumers’ attitudes toward MCCP were mediated by PE, PV, PC, and PI. The findings contributed to the theoretical study of MCCP design from the consumption value perspective and provided a theoretical basis for MCCP design development.

Authors: Rahmayani Melia Wida , Hernita Nita , Riyadi Wulan
Published: August 2023

Purpose: The purpose of this research is to analyze the relationship between company size and profitability and tax avoidance by coal mining firms.
  
Theoretical framework: Tax avoidance is a type of tax planning that has two sides: on the one hand, it is legal, but on the other, it is undesirable because it reduces government revenue.
 
Design/methodology/approach: The population of this quantitative study, which makes use of secondary data, consists of businesses from the coal mining sector that are listed on the Indonesia Stock Exchange between 2018 and 2021. Purposive sampling according to these criteria yielded a sample of 12 businesses for this analysis.
 
Findings: With the use of the SPPS Version 26 software, data is analyzed using descriptive analysis and verification analysis, such as the classical assumption test, multiple linear regression analysis, coefficient of determination analysis, and hypothesis testing. This research shows that company size and profitability significantly affect tax avoidance, either independently or together.
 
Research, Practical & Social implications: We propose a future study agenda centered on the ability to propose a research time frame and sample size in the hopes of maximizing the expected findings. To achieve more accurate data processing, you can also use different processes and data learning methods.
 
Originality/value: Previously, researchers found factors that determine tax avoidance. However, comprehensive information regarding the impact on tax evasion in Indonesia is lacking. This reinforces the robustness of our research.
Innovative Firm Performance Management Using a Recommendation System Based on Fuzzy Association Rules: The Case of Vietnam’s Apparel Small and Medium Enterprises
Authors: Giap Cu Nguyen , Ha Dinh Thi , Son Dao The , Hoai Ngo Thi
Published: August 2023

Purpose: This study aims to apply a classification algorithm based-on fuzzy association rules (FARs) to improve the effectiveness of firms' performance prediction problem. Particularly, this study investigates potential FARs exists between inputs and outputs of firms' performance management process. These extracted FARs could be used to help firm’s managers make better dicision to improve firm’s performance.

 

Theoretical framework: Private enterprise development has been identified as key to Vietnam's economy that was commonly depended on state enterprise. For that, understanding and improving firms' performance and productivity is one of the most important tasks, from both macro and micro perspectives. There have been many studies on Vietnam's firm performance, but mostly relying on econometric methods that limit the understanding with structural equations. This study, instead, attempts to utilize new achievements of Artificial Intelligence (AI) for this task. Among AI techniques, fuzzy association rule is able to address the relationship between input factors and firm performance indicators. For each company, the finding FARs can be used to predict its performance and then change the business plan or react to improve weekness of organization.

 

Design/Methodology/Approach: The proposal model is applied on data of small and medium-sized enterprises (SMEs) of the apparel industry in Vietnam in the period 2010-2015. The sample consist of a total of 23637 observation of  Vietnam firms in apparel and textile industry and contains 16 main criterias for those firms.

 

Finding: A recommendation system (RS) is constructed from disclosed FARs and is a key factor in a novel innovative firms' performance management process. The percentage of classified instances using the mining FARs is not quite high (about 82%), but it is not always the case. Vietnam’s apparel dataset includes rare classes of ROA, therefore applying only frequent FARs is not enough. This issue can be fixed by using both frequent and infrequent FARs.    

 

Research, practical & social implications: The proposed model has a great opportunity to use not only in the small and medium-sized enterprises (SMEs) of the apparel industry but other industrial sectors. FARs support the well-understand of firm performance to firm’s manager and help them better to react. Besides, FARs could be used to create RSs that makes alerts about risk automatically.

 

Originality/Value: The fact, our current study is the first to inspect the ability of FARs on SMEs of the apparel industry in Vietnam. This study provides theoritical potential knowledge and empirical evidence in the application of FARs technology in innovative firm’s management.

Published: August 2023

Los mecanismos de Fusarium oxysporum relacionados con la degradación de componentes estructurales de la raíz, como el xilano, son muy importantes, dado que la colonización de este órgano es pieza clave en el establecimiento de la enfermedad. El presente estudio se enfocó en detectar el gen codificante para la enzima xilanasa xyl3 en cepas de F. oxysporum f. sp. vanillae y buscar homólogos a este gen en secuencias de otras formae speciales y especies del género Fusarium, con el fin de determinar las relaciones filogenéticas entre las xilanasas dentro del complejo de especies F. oxysporum, así como, buscar evidencia de selección natural en el año 2020. Los resultados indicaron que, de las nueve cepas evaluadas, solo tres tuvieron una copia del gen xyl3. La filogenia mostró ocho clados, donde el clado 3 fue consistente con la clasificación de xyl3, mientras que los otros tipos de xilanasas quedaron agrupados en el clado 2. La prueba de selección natural no mostró evidencia de selección positiva dentro de la filogenia, lo que sugiere que la mutación neutral es la responsable de la diversidad en el gen xilanasa entre el complejo de especies F. oxysporum, lo que lleva a proponer que el gen no parece haber cambiado con la colonización de nuevos hospedantes.

Published: August 2023

In developing countries, malnutrition represents a public health problem, which affects many children under five, during their complementary feeding period. One way to overcome this problem is through the supplementation of complementary flours with locally available food resources, such as Moringa oleifera leaf (MOL). An experimental study was conducted from June through November 2019 in the southern-Benin, with moderately acutely malnourished (MAM) children, using a porridge made of a mixture of corn, malted sorghum, soybean, peanut, milk, and moringa leaf powder. A total of 150 MAM children aged 12-59 months were recruited and divided into two groups, an intervention group (48) and a control group (75). The intervention group received the test food, a porridge made of maize flour supplemented with Moringa oleifera leaf flour (MOL-flour), at least 5 times/week for 6 months. The control group, whose mothers received nutritional education sessions on food diversification as well as the different ways of preparing MOL meals. Sensory evaluation, anthropometric and dietary diversity data were collected. Z-scores Weight/Height, Weight/Age et Height/Age were determined before and right after the intervention. Results showed that 70% of the children and more than 75% of the mothers assessed the porridge as palatable. A significant average weight gain of 1.720 g (p < 0.005) was observed in the intervention group at the end of the experimentation, with a reduction of the prevalence of underweight by 1,33% (p > 0.05), and the number of acute Malnutrition children by 10,42% (p < 0.005).

El Aumento de D-Glucosa Extracelular Modifica el Estado de Metilación Global del ADN y la Función de Adhesión de las Células Progenitoras de Endotelio Humano Tempranas.
Authors:   , Gutiérrez Gallegos Soraya
Published: August 2023

Diabetes mellitus tipo 2 (DM2), constituye una enfermedad metabólica atribuida a factores genéticos y ambientales, que afecta las funciones angiogénicas de las Células Progenitoras Endoteliales Humanas (hEPC) las cuales no logran ser restauradas en respuesta a un buen control glicémico, manteniendo así, alterada su función en el tiempo. Por lo tanto, es probable que la exposición permanente a un ambiente con niveles de glucosa superiores a los valores plasmáticos normales (5mM o 90mg dl), produzca alteraciones a nivel epigenético que puedan explicar la mantención de las alteraciones angiogénicas en las EPC. En la presente investigación, hEPC fueron cultivadas durante 4 días (hEPC4d) en 5mM (90mg dl) de D-Glucosa, concentración equivalente a valores plasmáticos normales, 10mM (180mg dl) para simular una concentración de DGlucosa considerada como "clínicamente aceptable" en pacientes diabéticos, y 20mM (360mg dl) de D-glucosa para simular un ambiente hiperglicémico en pacientes diabéticos. Posteriormente, se evaluó la capacidad de adhesión de las células a una matriz de fibronectina. Para evaluar si las concentraciones de Dglucosa tenían impacto en los niveles de metilación global del ADN de hEPC-4d, se midieron los niveles de 5-metilcitosina (5mC), 5 hidroximetilcitosina (5hmC) y los niveles de expresión de los genes TET1 y TET2. Los resultados obtenidos indican que la suplementación del medio de cultivo con 20mM de D-Glucosa resulta en una disminución de la adhesión celular y adicionalmente, al cultivar las células hEPC-4d en 10mM y 20mM se puede observar una hipometilación global del ADN, y un aumento de 5hmC. Estos cambios en el patrón de metilación no fueron acompañados por cambios en los niveles de ARNm de los genes TET1 y TET2. Por lo tanto, se concluye que 20mM de D-glucosa genera una hipometilación del genoma en las hEPC-4d y una disminución de su capacidad de adhesión, fenómeno independiente de los niveles de expresión de los genes TET1 y TET2. Aunque la concentración de D-Glucosa considerada como glicemia "clínicamente aceptable" en un paciente diabético (10mM o 180mg dl), no produce cambios significativos en la adhesión de hEPC-4d, sí se observa una hipometilación global del genoma, que podría ser la responsable de la alteración de las funciones angiogénicas de estas células en pacientes que, desde el punto de vista clínico, tienen un buen control en los niveles plasmáticos de glucosa.

Published: August 2023

Parietaria judaica y Soleirolia soleirolii (Parietariae, Urticaceae) son hierbas perennes originarias del hemisferio norte que habitan ambientes urbanos y periurbanos en diversos países. En este trabajo, se actualiza el registro para P. judaica con nuevas localidades y hábitats en la provincia de Buenos Aires, se hace referencia a los focos de naturalización de S. soleirolii en Argentina, y se establece el estado de invasión para cada especie. Se estudiaron ejemplares de herbario de ambas especies coleccionados entre 1989 y 2022 en varias ciudades de la provincia de Buenos Aires y se documentaron los hábitats que ocupan mediante observaciones en las poblaciones naturalizadas. S. soleirolii se halló solamente en ambientes urbanos. Asimismo, se amplió el área de distribución de P. judaica con registros en numerosas ciudades de la provincia de Buenos Aires, en diversos hábitats de sectores urbanos y periurbanos. Presenta un amplio período de floración y fructificación. Se mencionaron sus probables agentes y vías de dispersión. Se aportaron imágenes ilustrativas de las especies y sus hábitats, mapas de la posición geográfica de las poblaciones halladas en Buenos Aires y, adicionalmente, una clave para diferenciar los géneros de la tribu Parietarieae en Argentina. El estado de invasión de las dos especies en Argentina es diferente. S. soleirolii no es actualmente una especie con alto potencial invasor. Por el contrario, P. judaica presenta una alta presión de propágulos, avanza probablemente por las vías del ferrocarril, por lo tanto, su potencial invasor es alto. Además, su polen es alergógeno.

Pillar is a part of the deposition of excavated material that is left behind to sustain the rock weight above it. The aim of this study was to determine the effect of height and diameter ratio on the strength of the pillar obtained from uniaxial compressive strength testing and numerical modeling. Laboratory test results showed that pillars with a ratio of 1.5 H/D did not show an increase in strength of 1.83%, while pillars with a ratio of 1 H/D gave a more significant increase in strength, which was 32.99%. The numerical modeling simulation with RS2 9.0 software showed that the strength factor values for pillars with an H/D ratio of 1.5, 2 and 1 having values below 1 at the same pressure as laboratory test results. Therefore, the most appropriate pillar design used in underground mining using the room and pillars method was a pillar with a ratio of H/D = 1.

Indonesia is a country that has quite large resources and reserves (3.25%) of the world's coal reserves. Indonesia's coal production in 2022 will reach 687 million tonnes to meet domestic and foreign (export) demand. Indonesia's coal production from year to year has an increasing trend. The existence of this upward trend can result in a decrease in the number of existing coal reserves. This study aims to predict the peak of coal production by estimating the age of the existing reserves. The data used is annual data from 1996 to 2021. The coal reserves used as a basis for consideration are 36,278.85 million tons. The methods used to forecast coal peak production and reserve age are the Hubbert, logistics, and Gomperzt models. The results obtained explain that the peak of coal production occurred in 2018 amounting to 0.539 billion tons with a coal reserve until 2081. For the logistic and Gomperzt models, the peak of coal production occurred in 2033 amounting to 1.345 billion tons and 0.7604 billion tons. Meanwhile, the reserve ages of the two models until 2080 and 2120.

The empirical model is applied to the trade data from 2005 to 2019 for 153 countries. We added the Korean Wave as a proxy variable by collecting Korean content service exports, which include music, dramas, and movies available on streaming sites and online video services, reflecting the recent shift in media platforms. We split the data into country groups and use the Poisson Pseudo Maximum Likelihood (PPML) to solve zero-trade data. Our findings show that the Korean Wave has a impact on both agricultural products and processed foods. Specifically, agricultural products are strongly influenced by the Korean Wave in Asia, while processed foods are influenced by more diverse continents. This suggests that the Korean Wave has a significant effect on agricultural food exports. We believe our study will be used as a fundamental study to prepare measures to increase agricultural exports through analysis by country.
Sinnlichkeit, Utopie und die »Arbeit gegen die Lebensangst«
Authors: Görlich Bernard
Published: August 2023

Alfred Lorenzer kritisiert Blochs Freud-Rezeption in den Fragen der Psychosexualität und des Triebbegriffs, sucht dann aber Elemente der Bloch’schen Utopie, vor allem die Idee des Noch-Nicht-Bewussten, zu verbinden mit seiner Auffassung einer nichtsprachlichen, leibzentrierten Sinnschicht, die sich als widerständig gegen das schlecht Bestehende erweist. Am Ende aber steht die Frage, was der Realisierung des utopischen Entwurfs entgegensteht, bzw. warum, mit Bloch gesprochen, das Hoffen stets von Scheitern bedroht ist.
Mit der Psychoanalyse und dem Surrealismus von der Paranoia zur Utopie?
Authors: Meisterhans Nadja , Graul Stefanie
Published: August 2023

Dieser Beitrag geht von einer gesellschaftlichen Krise des utopischen Denkens aus, welche auf die Identifikation mit neoliberalen Anrufungen zurückgeführt wird. Es soll deshalb im ersten Teil gezeigt werden, inwiefern neoliberale Ideologie dazu beiträgt, das Bestehende zu fetischisieren und zugleich eine normative Leerstelle hinterlässt, welche die Identifikation mit rechtsautoritären Verschwörungserzählungen begünstigt. Denn bei der neoliberalen Ideologie handelt es sich um eine zynische Anrufung, die dem autoritären Begehren wie auch apokalyptischem Denken in der Gesellschaft Vorschub leistet. Zugleich soll in dialektischer Perspektive im Anschluss an Jacques Lacan und Salvador Dalís kritisch-paranoide Methode verdeutlicht werden, dass sich im Wahnhaften durchaus Momente der Transgression und der Selbstbestimmung finden, die das Fundament utopischen Denkens bilden.
Microbiological examination of aerosols and sprays
Authors: Gunar O. V. , Sakhno N. G.
Published: August 2023

Medicinal products formulated as aerosols and sprays are increasingly used in clinical practice, which makes the control of their quality, including microbiological testing, a highly topical issue. The current regulatory standards for microbiological testing of medicines provide little information on the quality control of metereddose aerosols. Proper microbiological sampling of these medicinal products can be difficult because of their primary packaging. The specialised analytical procedures set forth in international standards require verification and standardisation before use. Medicinal products in the form of sprays, despite being free from the disadvantages of aerosols, are more susceptible to the risk of microbial contamination.

The aim of the study was to describe specific aspects of sampling, to analyse the results of microbiological testing of aerosols and sprays, and to study the spectrum of microbial contaminants in these dosage forms.

Materials and methods. The authors retrospectively analysed the microbiological quality and sterility data for 181 batches of sprays, aerosols, and other inhalation dosage forms. The data were obtained at the Scientific Centre for Expert Evaluation of Medicinal Products of the Ministry of Health of Russia in 2020–2022. The Microbiology Laboratory tested the dosage forms according to the specifications provided by the manufacturers. The analysts used well-established testing procedures outlined in the current pharmacopoeias of the Russian Federation and the Eurasian Economic Union.

Results. The microbial counts exceeded the acceptable limits in 2.8% of the batches tested. The authors identified the microbial species that contaminated the medicinal products found to be non-compliant with regulatory requirements. Most of the non-compliant sprays that contained benzalkonium chloride as an antibacterial preservative were contaminated with Burkholderia cepacia complex species.

Conclusions. The authors consider it relevant to conduct research aiming at using the findings on potential contaminants to improve microbiological testing procedures for aerosols and sprays.

Background: Resistant bacteria develop a high level of resistance to multiple drugs, limiting treatment options and increasing morbidity and mortality. This work was planned to evaluate the antibacterial potential of the methanol extract from the whole plant of Kalanchoe crenata (KCW) against multidrug-resistant (MDR) Gram-negative bacteria. Methods: The minimal inhibitory concentrations (MIC) and the minimal bactericidal concentrations (MBC) of KCW alone, in the presence of an efflux pump inhibitor (EPI) phenylalanine-arginine β-naphthylamide (PAβN), or in the presence of antibiotics were assessed using the broth microdilution method combined with the rapid para-iodonitrotetrazolium chloride (INT) colorimetric technique. Results: KCW displayed weak antibacterial activities with MIC values ranging from 128 to 1024 μg/mL against 10 of the 15 tested bacterial strains. Moderate antibacterial activities with MIC values ranging from 128-625 μg/mL were recorded against some strains belonging to Klebsiella pneumoniae, Escherichia coli, and Providencia stuartii. PAβN does not significantly enhance the activity KCW. At MIC/2, KCW potentiated the activity of doxycycline (DOX), levofloxacin (LEV), imipenem (IMI), ciprofloxacin (CIP), ceftriaxone (CRO), and tetracycline (TET) against at least 80% of the MDR bacterial strains tested. Conclusion: The present study demonstrated that KCW is a moderately active antibacterial agent, but a good efflux pump inhibitor that could potentiate the activity of antibiotics against MDR bacteria over-expressing active efflux pumps. Keywords: Antibacterial; antibiotic-potentiation; Crassulaceae; efflux pumps; Kalanchoe crenata; multidrug resistance.

Aim of this study was to identify the Candida isolates from Cancer Hospital Maharagama, Sri Lanka by using Multiplex PCR (polymerase chain reaction) method. In this study, Multiplex PCR was used to identify Candida isolates from cancer patients at Apeksha Hospital, Sri Lanka. In multiplex PCR, 18 specific primers (nine primer pairs) were separated into three groups for multiplex PCR (PS I, PS II and PS III). Different sized PCR products corresponding to each Candida species were produced by PCR using the primer mixes. Among 52 Candida isolates, 49 were identified using the multiplex PCR procedure. Candida tropicalis was found to be the most prevalent species (38%), followed by Candida parapsilosis (31%), Candida albicans (13%), Candida glabrata (8%) and Candida krusei (4%). The study concludes that multiplex PCR is a better approach for the identification of Candida species and recommends the use of it for clinical and diagnostic purposes and for research purposes.
Exploring The Prospects And Challenges Of Large Language Models For Language Learning And Production

Published: August 2023

The success of Large Language Models (LLMs) in many application domains suggests that they may also change how we conceive cognition. LLMs possess capabilities traditionally considered exclusively human. Can the experience with language alone facilitate the acquisition of other complex cognitive abilities? Do linguistic, sensorimotor, and interoceptive experiences need to be integrated? Are there domains, like that of abstract concepts (e.g., freedom), where linguistic experience suffices to capture meaning? After introducing what LLMs are, we address their potential impact, discussing five differences from human cognition: they are not grounded, lack action, hardly capture pragmatics, are culturally biased, and do not reflect individual characteristics.

This study explores the impact of multimedia teaching on senior high school students' Chemistry Practical performance. With technology increasingly becoming part of the learning environment, multimedia presentations are now utilised in schools to enhance students' learning experiences. Interactive Multimedia Learning, which incorporates visual and audio aids, is a teaching strategy that facilitates faster and easier comprehension of lessons. To compare the efficacy of Multimedia Teaching Method (MTM) and Traditional Teaching Method (TTM), this study was conducted in two senior high schools in Ghana: West Africa Senior High School and Frafraha Community Senior High School. The research design was quantitative, specifically quasi-experimental design and data were collected from 110 SHS 2 students using MTM and TTM. Descriptive and inferential statistics were used to analyse the collected data. The study findings revealed that most of the students taught using multimedia instruction performed significantly better in Chemistry Practical than those taught using the traditional method. These findings indicate that multimedia instruction can improve learning outcomes in chemistry. The study recommends using computers to supplement teacher instruction and not replace it. Teachers should continue to play a crucial role in the teaching process while integrating multimedia technology to enhance the learning experience.
