A novel approach to estimating the debt capacity of European SMEs
Authors: Karas Michal , Režňáková Mária
Published: July 2023

Research background: The concept of debt capacity assumes that a maximum value of debt ratio exists that when exceeded triggers unfavourable consequences, such as drop in market value, default or a change in the business' creditworthiness. With the current state of the art there is a priori no theoretical assurance that such a specific value exists, or rather it is represented by an interval of values. Beyond that, our understanding of debt capacity is often limited to a theoretical approximation by firm-specific factors, while the context of macroeconomic factors, especially those critical for SMEs, is neglected.
Purpose of the article: The aim of this paper is to present a novel approach to estimating SMEs' debt capacity. Further, the aim is to answer the question of what firm-level and macroeconomy conditions lead to exhausting the SMEs' debt capacity and under what conditions a specific value of maximum debt capacity could be estimated.
Methods: To estimate the debt capacity, we suggest a use of an information entropy minimising heuristic and the Minimal Description Length Principle. In this approach, the observed feature space is categorised into several regions. In this case, such a region represents a set of firm- and macroeconomy-specific conditions forming the debt capacity of the SMEs. To the best of our knowledge, such an approach has not yet been used in debt capacity applications.
Findings & value added: We found out that the debt ratio itself provides little explanation of exhausted debt capacity, suggesting that high debt levels are compensated for by other factors. By using the suggested approach, a set of more than 100 different regions was analysed. It was found that in case of five regions (sets of conditions) the debt capacity is exhausted, as the high level of debt has significant distress consequences.

Published: July 2023

Objectives: This study aimed to examine the scale, characteristics, risk factors, and modes of transmission in a coronavirus disease 2019 (COVID-19) outbreak at a high school in Seoul, Republic of Korea.Methods: An epidemiological survey was conducted of 1,118 confirmed cases and close contacts from a COVID-19 outbreak at an educational facility starting on May 31, 2021. In-depth interviews, online questionnaires, flow evaluations, and CCTV analyses were used to devise infection prevention measures. Behavioral and spatial risk factors were identified, and statistical significance was tested.Results: Among 3rd-year students, there were 33 confirmed COVID-19 cases (9.6%). Students who used a study room in the annex building showed a statistically significant 4.3-fold elevation in their relative risk for infection compared to those who did not use the study room. Moreover, CCTV facial recognition analysis confirmed that 17.8% of 3rd-year students did not wear masks and had the lowest percentage of mask-wearers by grade. The air epidemiological survey conducted in the study room in the annex, which met the 3 criteria for a closed space, confirmed that there was only 10% natural ventilation due to the poor ventilation system.Conclusion: To prevent and manage the spread of COVID-19 in educational facilities, advance measures that consider the size, operation, and resources of each school are crucial. In addition, various survey methodologies should be used in future studies to quickly analyze a wider range of data that can inform an evidence-based quarantine response.

IDIORRHYTHMIC INQUEST: SYLVESTER, PATRIARCH OF ALEXANDRIA, JEREMIAH II, PATRIARCH OF CONSTANTINOPLE, AND THE MISSION TO RESTORE COMMUNAL MONASTICISM ON MOUNT ATHOS IN THE 1570s
Authors: CHITWOOD Zachary
Published: July 2023

Over the second half of the sixteenth century, a new form of monasticism, idiorrhythmia (“living according to one’s own devices”), seemed to be spreading across the Orthodox monasteries of the Eastern Mediterranean. The communal regime practiced for centuries in the venerable monasteries of the East was gradually collapsing: first at St. Catherine’s on Sinai around 1557, then at the monasteries of Palestine, including the Monastery of the Cross in Jerusalem. When the patriarchs of Alexandria (Sylvester [1569-1590]) and Constantinople (Jeremiah II [1572-1579; 1580-1584; 1587-1595]) came together to celebrate Christmas at Thessaloniki in 1573, Sylvester was tasked with travelling to Mount Athos to investigate the state of the monastic life there. His inquest revealed a shocking state of affairs: monks moving without hindrance to and from Athos and engaging in the sale of goods to the outside world, including spirits which they drank themselves. Beardless youths and laypersons lived in monasteries; livestock were allowed to pasture on the Holy Mountain. This contribution will examine Patriarch Sylvester’s inquest and the subsequent effort to restore communal life at the major monasteries on Athos.

Authors: Mercader Ruiz Jessica , Siegenthaler Hierro Rebeca , Abellán Roselló Laura , Bellmunt Barreda María Jesús
Published: July 2023

Diferentes factores interdependientes entre sí se han relacionado con el rendimiento matemático. Entre ellos, destacan factores cognitivos generales y específicos, factores afectivo-motivacionales y factores contextuales. Este estudio analiza el impacto de las actitudes competencia percibida y valor de utilidad sobre el rendimiento matemático y sus diferentes bloques. También explora las diferencias en dichas actitudes entre niños con rendimiento bajo (RB), rendimiento medio (RM) y rendimiento alto (RA). La muestra consistió en 91 estudiantes (11-12 años). Las variables de rendimiento matemático y motivacionales se evaluaron mediante la Batería para la Evaluación de la Competencia Matemática Básica y el Inventario de Actitudes hacia las Matemáticas. Los resultados obtenidos indican que la variable motivacional con mayor relación y poder predictivo es la competencia percibida. La variable valor de utilidad aporta una contribución significativa adicional a la explicación del rendimiento matemático. Aparecen también diferencias entre los grupos de RB, RM y RA en competencia percibida. Además, desde un enfoque preventivo, la competencia percibida es un aspecto que tener en especial consideración, sobre todo en alumnado con RB. El estudio sugiere que la motivación, tiene un papel importante sobre el rendimiento matemático al final de la etapa primaria. En este sentido, es esencial proponer retos relevantes y alcanzables, ofreciendo feedback para que los estudiantes generen creencias ajustadas a sus capacidades reales. Por último, familias y docentes deben brindar ambientes positivos de aprendizaje, con múltiples oportunidades de participación y acompañamiento para afrontar con éxito los aprendizajes matemáticos en la Educación Primaria, sobre todo, en los últimos cursos.

Published: July 2023

Background and Purpose: The initiatives to improve the students’ competency level is closely related to the quality of the lecturers. Lecturers play a very crucial role because they are responsible for teaching students of higher education institutions. A high-quality lecturer is believed to greatly influence their students’ ability and competency. This study is to identify the level of lecturers’ quality based on role-performance in teaching Mandarin in MARA Education Institutions (IPMA), specifically in Kolej Profesional MARA (KPM), Kolej Universiti Poly-Tech MARA (KUPTM) and Universiti Kuala Lumpur (UNIKL).
 
Methodology: This descriptive study used a survey method to collect data. The respondents comprise a population of students who study Mandarin as a third language course in IPMA, which is represented by Universiti Kuala Lumpur (UNIKL), Kolej Universiti Poly-Tech MARA (KUPTM), and Kolej Profesional MARA (KPM). 150 students were selected as respondents in the present study using a purposive sampling rather than random sampling. A Likert scale questionnaire is used to gather the data and SPSS software is used to statistically analyze the data.
 
Results: Based on the mean value interpretation, the findings revealed that the lecturers’ quality on role-performance falls under a Very High level (M=4.63, SD=0.49) which simultaneously indicated that these Mandarin lecturers had the desired professional qualities and were committed to high quality teaching practice.
 
Contributions: These findings provide a better insight into the teaching of Mandarin in tertiary level education in Malaysia and in return can help to tailor professional learning activities to the professional development needs of lecturers.     
 
Keywords: Lecturer quality, role-performance, Mandarin language, IPMA.

THE INTEGRATION OF CULTURAL ELEMENTS IN THE ENGLISH LANGUAGE CLASSROOMS: A CASE STUDY OF SELECTED ORANG ASLI SCHOOLS IN PAHANG, MALAYSIA
Authors: Idrus Faizah , Hussin Muhammad Ekram , Gulca Mahinur
Published: July 2023

Background and Purpose: This study examined the challenges faced by the Orang Asli students from the Jah Hut tribe and their reactions towards the integration of their cultural elements in learning the English language at two Orang Asli schools in Temerloh, Pahang, Malaysia. It also sought to investigate students’ and teachers’ motivation in learning and teaching the subject.
 
Methodology: This critical qualitative inquiry employed a case study approach employing semi-structured interviews and non-participant classroom observations. A total of 14 participants were selected through purposive sampling technique, which consisted of ten Orang Asli students, three Orang Asli teachers, and one Malay teacher from two Orang Asli’s schools in Temerloh district.
 
Findings: The findings indicated that integrating the Orang Asli’s own culture into the English lessons had captivated their interest immensely. The most motivating and stimulating lessons were centred around cultural celebrations, the use of the native language, cooking the Orang Asli delicacies, and parading and explaining their outfits and costumes.  Teachers responded to the importance of Culturally Responsive Teaching strategies’ acceptance and use in the classrooms regardless of the composition of the students. Similarly, they felt that the knowledge of understanding the cultures of others is critical as it allows one to understand the struggles, and slowly develop a sense of appreciation towards differences.
 
Contribution:  The study highlights pertinent information regarding the issue of a ‘one size fits all curriculum’, especially in the teaching of the English language with the diversity of people in Malaysia. It also provides suggestions on classroom teaching strategies for multicultural classrooms. It also adds input to the existing literature on the integration of cultural elements in the teaching of the English language to the Orang Asli students.

Authors: Abdullah Muhammad Fuad , Mohd Noor Mohd Iqbal , Tedong Peter Aning , Ahmad Zaini Azniza , Abd Kadir Nor Aziah , Abdullah Mohd Tajuddin
Published: July 2023

Background and Purpose: Parents play a crucial role in children's educational attainment. Their perception influences their action in giving better formal education to their children. However, the scenario is different for the Indigenous community in Malaysia where formal education is deemed least important and there is a huge gap for Indigenous education attainment compared to the stream population. This paper aims to elucidate the parent perception of formal education effectiveness among the Indigenous community or Orang Asli (in the Malay language) in Terengganu, Malaysia.
 
Methodology: The research using qualitative methods involved three Indigenous villages in the state of Terengganu. Data were collected through interviews, focus group discussions and observation. The informants consisted of Indigenous parents, teachers and the officers of the Department of Orang Asli Development (JAKOA).
 
Findings: Results showed that parents' perceptions are generally stereotyped and unable to stimulate students’ interest. The common problem in teaching and learning is related to parents’ educational background, socioeconomic background, expectations, marital age, surrounding condition and awareness.
 
Contributions: This study has given the real picture of Indigenous parents' perceptions toward formal education. The implications of Indigenous parents’ education problems are significantly associated with degrading interest among students in education, issues of attendance and students' academic performance.

ACHIEVEMENT MOTIVATION AMONG ISLAMIC STUDIES STUDENTS AND ITS CORRELATION WITH PROBLEM BASED LEARNING AND SELF-EFFICACY
Authors: Islam Tazul , M. Zayed Tareq
Published: July 2023

Background and Purpose: Achievement Motivation defines motivation as a concept that forecasts the behavioural inclination to strive for success and performance based on a person's urge for achievement. The purpose of this study was to examine the link between academic self-efficacy and problem-based learning (PBL) and achievement motivation among students of Islamic studies.
 
Methodology: A quantitative research design was used for this explanatory investigation. 578 undergraduate students from three institutions in Malaysia—UM, IIUM, and USIM—totaled took part in the study. The participants were chosen at random. Both descriptive statistics and regression analysis were used to analyse the data set. Additionally, an intergroup comparison analysis and the independent sample t-test were performed.
 
Results: The results of an independent sample t-test showed a significant difference in the mean achievement motivation scores between students of applied Islamic studies (M = 3.31, SD =.41) and those of non-applied Islamic studies (M = 3.04, SD =.38). This difference is statistically significant at t (575) = -7.94, p =.00. When ASE was controlled, PBL's influence on AchM diminished (Sobel z= 3.83, p=0.00), indicating that ASE was the mediator of the relationship between PBL and AchM. F (7, 570) = 22.42, p .0005, adj. R2 =.206, multiple regression substantially predicted ASE. The outcome demonstrates that the method used to solve problems and the kind of programs used may both be effective predictors of students' academic self-efficacy in Islamic studies.
 
Contribution: The study concludes that achievement has a big impact on students’ motivation. The findings of the study may contribute to the departments of Islamic studies and the Ministry of Higher Education in Malaysia (MoHE) in understanding the present issue of achievement motivation, as the ministry's goal is to increase students' self-efficacy. The study has implications on Islamic Studies students at higher learning institutions to boost their motivation.

Authors: Ling Pick-Soon , Mohd Ossman Nurul Sarah , Mohamad Abdul Hayy Haziq
Published: July 2023

Background and Purpose: With the acceleration of mobile payment usage in the daily routine, this study intends to examine the determinant factors on the users’ behavioural intention on the Sarawak Pay using the theory of reasoned action (TRA), technology acceptance model (TAM), unified theory of acceptance and use of technology (UTAUT), and a modified model.
 
Methodology: A total of 195 Sarawak Pay users was selected using the purposive sampling technique to collect their responses through the questionnaire-based online survey. The PLS-SEM was utilised to examine the proposed hypotheses.
 
Findings: The study found that the modified model had the greatest explanatory and predictive power than the other conventional models. Moreover, the performance expectancy, facilitating conditions and attitude positively influenced the behavioural intention and use behaviour on the Sarawak Pay, while effort expectancy had a contrary effect. Furthermore, the social influence failed to impact the Sarawak Pay users’ behavioural intention and their use behaviour.  
 
Contributions: The findings offered a clear understanding of the drivers and inhibitors that inspired the users’ behavioural intention and their use behaviour on the Sarawak Pay, as it had a critical implication for the Sarawak government. This evidence was derived from three conventional models and a modified model.

Effects of pelvic suspension of beef carcasses and wet aging time of cuts on eating quality and sensory scores of 14 muscles
Authors: Pogorzelski Grzegorz , Pogorzelska Ewelina , Wierzbicka Agnieszka
Published: July 2023

To evaluate the effect of carcass hanging method and aging period on beef eating quality young cross-breed bulls were slaughtered in a slaughterhouse in south-eastern Poland. After the slaughter operations were completed, one carcass side was hung by the Achilles tendon and the other by the hip bone. Suspension methods depending on the carcass sides were used in rotation. Consumer samples were prepared from 14 muscles collected from each of the 50 sides. The use of different hanging methods showed their varied impact on tenderness, juiciness, flavour overall liking and eating quality of beef cuts. A positive effect of tenderstretch on eating quality was observed for six of the muscles (longissimus thoracis, spinalis dorsi, longissimus lumborum, vastus lateralis, gluteus profundus and semimembranosus), no effect was observed for seven, and a negative effect of suspending carcass by hip bone was noted for just one muscle.
Biodiversity in cities: the impact of biodiversity data across spatial scales on diversity estimates
Authors: Garzon Lopez C.X. , Savickytė Gabija
Published: July 2023

The assessment and monitoring of biodiversity in urban areas has been shown to have enormous potential to inform integrative urban planning in cities. In this context, digital biodiversity repositories such as the Global Biodiversity Information Facility (GBIF) has been promoted for its central role in gathering and harmonizing biodiversity data worldwide, thereby facilitating these assessments and monitoring efforts. While GBIF data has been investigated for its potential at a large scale and in natural ecosystems, the question remains as to what extent, and in which context, is GBIF data applicable to urban biodiversity assessment and monitoring? In this study, we assessed the spatial patterns of biodiversity, by exploring species richness patterns in relation to land use types for three taxonomic groups (birds, mammals and arthropods) in three cities in The Netherlands (Rotterdam, Amsterdam and Groningen) at multiple spatial scales. We found significant variation in the effect of land uses on the species richness patterns, in terms of taxonomic group, spatial configuration and land cover type, and across spatial scales. Our study demonstrates the potential of GBIF data while highlighting the importance of the careful selection of one or multiple spatial scales, especially in relation to the taxonomic group characteristics and ecology and the spatial configuration of the cities studied.
A test battery approach for ecotoxicological evaluation of disinfectants prepared on the basis of sodium hypochlorite
Authors: Fargašová Agáta , Nawaz Ammara , Molnárová Marianna
Published: July 2023

The research is related to the assessment of the overall sensitivity and applicability of many bioassays representing different trophic levels for the preliminary ecotoxicological testing of commercial disinfectants marked as SA (SAVO, Bochemie a.s., Czech Republic) and DoAm (Dom Amor, BOOS – Biologické substancie, Slovak Republic). Disinfectants were prepared based on sodium hypochlorite (NaOCl). SA contains only NaOCl while earthworm enzymes enrich DoAm. In both commercial products, the NaOCl content did not exceed 5%; pure NaOCl was used as a 10% solution as well. For bioassay, water organisms (Vibrio fischeri, Desmodesmus subspicatus, Daphnia magna and Tubifex tubifex) situated in various trophic levels were used. All the tests were confirmed as suitable for the determination of chlorine’s adverse effects. Because the organisms’ reactions to the tested disinfectants varied, they can be arranged in the following rank order of sensitivity: V. fischeri ≥ D. subspicatus >> D. magna >> T. tubifex. The toxicity of the tested substances (NaOCl, SA, DoAm) depends on the length of exposure, the species of the organism and FAC (free available chlorine) content. The effective concentrations of the tested products ranged from 0.13 to 8.18 μL L–1, i.e., 0.014 to 0.26 mg L–1 of FAC. However, in the tests with T. tubifex and V. fischeri the toxic effect of NaOCl was the weakest; the tests with other two organisms confirmed this compound as the most toxic. Only for T. tubifex (96 hrs) did SA have a more adverse effect than DoAm.
Seed germination behavior of Teucrium santae Quézel & Simonneau: a vulnerable and endemic Lamiaceae (Northwest Algeria)
Authors: Bentekhici Meriem , Mehdadi Zoheir , Latreche Ali
Published: July 2023

As part of the ex-situ conservation of the rare plant species Teucrium santae (Lamiaceae), which is native to Algeria flora, we conducted this study under controlled conditions to determine the optimal circumstances for the germination of its seeds in terms of light, temperature, and water stress. The seeds showed a double dormancy that could be overcome using scarification with sulfuric acid combined with soaking in Gibberellic acid at 1,500 ppm. The seed’s photosensitivity was tested afterward and found to be indifferent. The highest final germination percentage (75%) was obtained at a temperature of 20 °C. The temperature has no significant effect on the velocity coefficient, unlike the initial germination day and the mean germination time which decrease with increasing temperature. On the opposite of the velocity coefficient, water stress results in a tremendous depressive effect on the final germination percentage, initial germination time and mean germination time. The value of –1.2 MPa constitutes the water potential beyond which germination becomes impossible.
Modern approach to the management of genitourinary syndrome in women with gynecological malignancies
Authors: Kovacevic Nina , Cilensek Ines , Merlo Sebastjan , Segedin Barbara
Published: July 2023

Background

The term genitourinary syndrome of menopause was first used in 2014 by the North American Menopause Society and the International Society for the Study of Women's Sexual Health to describe conditions previously known as atrophic vaginitis, urogenital atrophy, or vulvovaginal atrophy. It is a complex, chronic, progressive condition characterized by a wide range of signs and symptoms affecting sexual function and the tissues of the urinary and genital tracts. The main cause of genitourinary syndrome of menopause is estrogen deficiency caused by ovarian removal or dysfunction. The most bothersome symptoms are vaginal dryness, decreased vaginal lubrication, and pain during penetration and intercourse. They all have a negative impact on the quality of life.

Conclusions

The main goal of treatment is to relieve the symptoms. Treatment modalities are pharmacological or non-pharmacological. The first-line treatment for mild to moderate symptoms is the use of personal lubricants and moisturizers, but the gold standard is estrogen replacement therapy. Hormone therapy may not be an option for women with hormone-dependent cancer.
The portrait of a stranger: the hypereosinophilic syndrome with cardiac involvement
Authors: Ivănescu Andreea-Cristina , Petre Alexandru , Marincaș Andrei Sabin , Bădilă Elisabeta , Dan Gheorghe-Andrei
Published: July 2023

Introduction

Hypereosinophilic syndrome is a rare clinical condition, and cardiac involvement confers a poor prognosis. Hypereosinophilic myocarditis is a medical emergency and targeted treatment should be started promptly even before a definitive diagnosis could be made.

Case presentation

A 27-year-old female patient is hospitalized for exertional dyspnea, chest pain, and fatigue for the past 2 weeks. She also describes left leg paresthesias. Clinical examination was in normal limits. ECG showed sinus tachycardia, QS pattern in V1–V4, and diffuse flattened T waves. Laboratory tests revealed increased inflammatory markers, hypereosinophilia, elevated cardiac enzymes, high NT-proBNP. Echocardiography revealed LV dysfunction (EF 31%), while cardiac MRI showed diffuse delayed enhancement with predominant subendocardial disposition. The electromyogram was suggestive of left tibial nerve neuropathy.

We interpreted the case as eosinophilic myocarditis with an urgent requirement of therapy and initiated high-dose glucocorticoid therapy and the GDMT 4-pillar heart failure treatment. We excluded common infectious, myeloproliferative syndromes, and frequent associated autoimmune diseases. With prednisone, the eosinophil count rapidly normalized and we gradually tapered the dose by 5 mg per week, however continuing with heart failure therapy. At monthly follow-up visits, there was a significant clinical improvement, with normalization of the eosinophilic count, and a near-normalization of myocardial function. The only symptom that persisted was paresthesias linked to left tibial neuropathy.

Conclusion

The surprisingly rapid and favorable course of the disease offers a high index of suspicion for a toxic or a reactive transitory etiology, however still unidentified. In our case, the cause of eosinophilia remained unknown, although we managed to narrow down the possible etiologies. A surprisingly good clinical response was obtained with non-specific treatment targeting mainly hyperosinophilic myocarditis.

Published: July 2023

Introduction

The cortical bone is the most severely affected site in patients with primary hyperparathyroidism (PHPT) and thus, a low bone mineral density (BMD) is predominantly observed in distal forearm. Several studies have investigated potential associations between the weight of the gland and bone mineral loss. In this study, we wanted to investigate the relationship between parathyroid adenoma (PTA) volume and bone mineral loss.

Methods

All patients with a diagnosis of PHPT who were operated at our hospital, and with a histologically proven single PTA were retrospectively analyzed. Z-scores were used as the main variable in our analysis to eliminate the effects of age, sex and gonadal status on BMD.

Results

Total of 153 patients who met the inclusion criteria were eligible for the study. A significant negative correlation between the PTA volume and z-score for distal third of the radius (DR) (p = 0.006, r = -0.297) was shown. The cut-off value of gland volume for predicting cortical bone mineral loss was 9043.2 mm3. There was also a significant negative correlation between the 24-hour urine calcium and z-scores for lumbar vertebrae and total hip. A significant negative correlation was found between preoperative 25-hydroxy vitamin D levels and the PTA weight.

Conclusions

As the first study that evaluated any possible association between the volume of a parathyroid adenoma and bone mineral loss in patients with PHPT, we found a significant negative correlation between DR z-scores and resected gland volume. Since the volume of a PTA can also be determined by a preoperative US, our findings may be helpful during the preoperative evaluation of a patient with a preliminary diagnosis of PHPT.
NUT carcinoma in head and neck region: Case report with literature review
Authors: Patil Dipti , Patil Pradipta , Pol Jaydeep , Kadkol Girish , Phadke Madhura
Published: July 2023

Squamous cell carcinoma (SCC) has several variants based on its histopathological features. Nuclear protein in testis (NUT) carcinoma (NC) is a rare and aggressive variant of SCC, previously described exclusively in midline sites. The histopathological features of NC are similar to poorly differentiated carcinoma or undifferentiated carcinoma. Abrupt keratinization in an otherwise undifferentiated carcinoma is an important diagnostic clue. The confirmatory diagnosis is dependent on molecular techniques such as Immunohistochemistry, Fluorescent in situ hybridization technique or RT-PCR to detect mutations in NUT gene. It is most commonly found in middle aged, in lungs and head and neck regions. Since NC features overlap with poorly differentiated and undifferentiated carcinomas, these cases need to be suspected and evaluated for NUT gene mutations thoroughly. Due to their rarity and less known facts, NC cases are required to be reported on large scale.

Here, we report a middle-aged woman with a mass on the forehead diagnosed as NC based on molecular evaluation, with a review of the literature emphasizing the rarity of NUT carcinoma and the importance of careful histopathology as well as immunohistochemistry evaluation.

One of the vital roles played by both magnetic and radiometric surveys is identification and delineation of mineral deposits. The study area, Imeri, which lies between latitude 6 °45′N to 6 °48′N and longitude 3 °58′E to 3 °59′E, has been established for bitumen deposition. The responses of mineral deposition to different geophysical methods differ from place to place due to variation in climate and bedrock composition. In this study, two geophysical techniques—magnetic and radiometric methods—were adopted to investigate the magnetic anomalous and radiometric flux responses around the bitumen deposit area. The study also intends to establish a model-like relation between the radiometric parameters and the magnetic anomaly observed. Statistical inferences for the established relations were deduced using the t-test at 0.05 significance levels. The result obtained showed that uranium and thorium concentration responses along the two traverses were in good agreement with that of magnetic intensity. The claim was accounted for based on the correlation result, which ranged between 74%–79% and 84%–89% for uranium and thorium, respectively, with magnetic intensity along the two traverses. In order to validate the claim, the t-test was used. The result obtained showed that there exists no significant difference between the two geophysical methods; the result for the t-test has critical value > calculated value (p-values > 0.05). Based on this, the empirical relations were deduced for magnetic anomalous response and radiometric parameters. This work has therefore proven the two techniques to be versatile for bitumen prospecting in the study area.

The current study tries to assess the implications of GST adoption on the revenue efficiency of the Indian states. The results indicate that the GST implementation has increased the C-efficiency ratio of the country. Similarly, at the sub-national level, the GST implementation has increased the revenue efficiency for the consumptive and minor Indian states i.e. Manipur, Mizoram, Meghalaya, Assam, Sikkim and Nagaland. Although, the developed states still have a higher share of total GST revenue in the country, but the adoption of GST will mitigate the inter-state disparity by shifting the revenue streams from the productive states to consumptive and minor states. On the contrary, the stability analysis indicates that the GST adoption has increased the volatility in the revenue of the state governments. The finding of the study has major implications for the state and central governments, policymakers, researchers and the sitting of the fifteen finance commission in India.

This paper is dealing with the adoption of digital financial services on the performance of commercial banks in India. The study used camel rating system to measure pre and post adoption performance of commercial banks. The reports says that Indian banks are widely adopted digital financial services during the year 2012-13. Hence, 2004-05 to 2011-12 considered as pre adoption period and 2012-13 to 2019-20 considered as post adoption period for the data analysis. 44 banks were selected for the study based on the data availability. 15 camel ratios were identified and paired t-test used for analysis. The study found that most of the CAMEL (capital adequacy, assets, management capability, earnings, liquidity) variables are found significant to improve the financial performance of banks. The coefficient of digital financial services variables is found to be significant. This indicates that facilities of digital banking could enhance the financial performance of banks.

Kelelawar menempati berbagai habitat sebagai lokasi bertenggernya, salah satu lokasi potensial adalah gua lava (lava tube). Gua merupakan ekosistem yang memiliki faktor lingkungan spesifik namun rentan terhadap kerusakan akibat aktivitas manusia. Perubahan lingkungan yang terjadi di dalam gua berpotensi mengganggu aktivitas bertengger kelelawar di dalam gua, sehingga dapat menyebabkan penurunan populasi kelelawar. Ekosistem gua lava digunakan sebagai lokasi bertengger oleh kelelawar namun masih sedikit informasi mengenai keragaman kelelawar dan faktor lingkungan gua yang berpengaruh terhadap keragamannya. Penelitian ini bertujuan untuk mengetahui keragaman dan kelimpahan kelelawar dan hubungannya dengan faktor lingkungan. Pencuplikan kelelawar dilakukan melalui pemasangan jaring kabut di depan pintu masuk gua untuk mendapatkan data kelimpahan dan kekayaan spesies kelelawar. Kekayaan spesies dan indeks diversitas dianalisis menggunakan program SpadeR (Species-Richness Prediction and Diversity Estimation with R), sedangkan analisis hubungan antara faktor lingkungan terhadap keragaman kelelawar dianalisis menggunakan korelasi Spearman menggunakan Rstudio 4.1.1. Kelelawar yang didapatkan merupakan kelelawar pemakan serangga yang terdiri dari tiga famili (Vespertilinoidae, Rhinolophidae, dan Hipposideridae). Jumlah spesies yang didapatkan sebanyak tujuh spesies dengan total 121 individu tertangkap, yaitu Miniopterus austalis, Rhinolophus affinis, R. pusillus, R. canuti, Hipposideros ater, H. diadema, dan H. larvatus. Kelembapan adalah faktor lingkungan yang berkorelasi positif signifikan (p<0.01) terhadap kekayaan spesies dan kelimpahan kelelawar di ekosistem gua lava. Keragaman kelelawar di ekosistem gua lava yang relatif tinggi (H’=1.4±0.1, H’=1.2±0.1), menandakan bahwa lingkungan gua masih menjadi pilihan kelelawar sebagai lokasi bertengger, meskipun kedua gua di dalam ekosistem ini mengalami gangguan berupa kunjungan manusia akibat kegiatan wisata.

The manufacturing industry in the current era of globalization is very strict. Speed to produce products is important now, not only in terms of process. Developing a new product at PT. Surya Toto Indonesia has been running well, only in the process there are still found the exceeded of time or schedule of work plans that have been made. The preparation process for carrying out this test will take more time. Because the test aids have not been prepared or have not been grouped according to the type of finished goods or according to the series. It is necessary to analyze using the seven tool method and assisted by factor analysis to find the dominant cause and corrective action. It was found the old problem in the inspection process was the dress-up process or preparation for the test. Because the test kits are incomplete and not permanent, also the test kits do not have a storage area and lack of employee’s ability to process them. Employee education, complete equipment components, and also need to make permanent test kits and according to the specifications of finished goods. Storage area for the test kits so that it is not scattered and messy.

The wheels are a vital component for safety in driving as well as supporting the vertical load of the vehicle when the vehicle is rotating or at rest and serves as a continuation of the rotary motion of the engine to move from one place to another. These wheels are used in a motorcycle made from ironand aluminum alloys material.We perform the tensile and hardness test to obtain their strength and hardness value. We found from our measurement that the maximum tensile stress for the aluminium and iron velg are 155.08 MPa and 277.62 MPa, respectively. The values are directly proportional with the hardness of those material, in which the hardness of iron velg is much higher than that one of aluminium velg by 521.8 VHN.
Investigación académica y prácticas artísticas ambientales latinoamericanas
Authors: Blackmore Lisa , Heffes Gisela
Published: July 2023

El presente dossier reúne cuatro artículos que demuestran cómo un número de estudios recientes, junto a prácticas de arte y de diseño se encuentran reconfigurando el campo emergente de las humanidades ambientales latinoamericanas —una disciplina en rápida consolidación que nutre métodos y perspectivas derivados de las ciencias sociales, las artes y las humanidades; las ciencias naturales y el pensamiento indígena— con el fin de interrogar críticamente las historias ambientales y enfrentar los desafíos contemporáneos. Juntos, los artículos reunidos en estas páginas mapean una renovación crítica de los estudios culturales que está ocurriendo a través de publicaciones teórico-analíticas recientes, trabajos etnográficos, prácticas artísticas y colaboraciones de arte y diseño en territorios específicos. Más aún, trazamos rutas a través de un corpus diverso de estudios ambientales emergentes, investigación de prácticas artísticas situadas, y actividades de participación pública, para destacar cómo responden al desafío urgente de «pensar en presencia de hechos de destrucción vigentes» (Stengers 2013, p.186). Las investigaciones académicas, las obras de arte y los proyectos de trabajo de campo colaborativo reseñados aquí problematizan la dicotomía cultura/naturaleza como constitutiva de las actuales crisis ecológica y climática, reconsideran las premisas de la metafísica occidental ontológica y semiótica, y siembran experimentos simpoéticos y formas alternativas de conocimiento que trascienden las divisiones disciplinarias.
