Authors: Omar Timor , Hamideyin Şerif , Karakayali Muammer , Artaç İnanç , Karabağ Yavuz , Dündar Cihan , Rencüzoğullari İbrahim 
Published: August 2023

Objectives:
This study aimed to investigate the relationship between subclinical left ventricular (LV) systolic dysfunction and ECG parameters in newly diagnosed hypertension patients.

Methods:
In this cross-sectional study, adults diagnosed with hypertension based on 24-h ambulatory blood pressure monitor recordings were included. The patients were classified into two groups based on the presence of subclinical LV systolic dysfunction according to LV global longitudinal strain (LVGLS). Findings were compared between the two groups.

Results:
A total of 244 patients (female, 55.7%) were included. Based on LVGLS, 82 (33.6%) patients had subclinical LV systolic dysfunction. The proportion of early repolarization pattern (ERP) on ECG was significantly higher in patients with subclinical LV systolic dysfunction than in patients with normal LV systolic function [24 (28.6%) vs. 8 (5%), P < 0.001]. PR and corrected QT intervals were also significantly longer in patients with subclinical LV systolic dysfunction than in patients with normal LV systolic function [median (interquartile range), 148 (132–158) vs. 141 (127–152), P = 0.036 and 443 (427–459) vs. 431 (411–455), P = 0.007, respectively]. According to multivariate regression analysis ERP, early (E) wave velocity/late (A) wave velocity (E/A), and LV mass index were independently associated with subclinical LV systolic dysfunction.

Conclusion:
In newly diagnosed hypertension patients, the ERP on admission ECG could be a sign of subclinical systolic dysfunction.

Published: August 2023

Introduction and importance:
Acute pancreatitis is an inflammatory disease that can affect both the peripancreatic tissues and distant organs. There are few reports of acute pancreatitis caused by endourological procedures. However, an obstructing ureteral calculus causing acute pancreatitis is very rare.

Case presentation:
A 36-year-old male patient presented with epigastric, and right loin pain with decreased urine output for 3 days. On physical examination, he had central abdominal and right flank tenderness. An abdominal ultrasound showed mild to moderate ascites, a hyperechoic pancreas, a small (26×77 mm) left kidney with increased echogenicity, right renal hypertrophy with moderate hydronephrosis, and a dilated upper ureter due to a 10 mm obstructing stone with a perirenal fluid collection. The diagnosis of acute pancreatitis with an obstructing right upper ureteric stone was established. Under spinal anesthesia, an emergency ureteroscopy with laser fragmentation of the stone was performed, and a JJ stent was inserted. He developed postobstructive diuresis and his renal function was improved with a rapid decline of pancreatic enzymes as well.

Clinical discussion:
Two theories explain the presentation of acute pancreatitis by ureteral obstruction. First, the obstructed severe hydronephrotic kidney compresses the duodenum and head of the pancreas, obstructing the distal part of the common bile duct and triggering the elevation of pancreatic duct pressure, bile reflux, trypsin activation, and pancreatic autodigestion. The second theory states that acute pancreatitis develops when urine is extravasated from an obstructed kidney into the adjacent tissues, irritating the uncinate process of the pancreas.

Conclusion:
Although mentioning ureteral obstruction as a cause of pancreatitis is scarce, the clinician should be aware that in each case of ureteral obstruction, the emergence of acute pancreatitis is a possible complication.
Pasture shooting and mobile slaughterhouses from a consumer's point of view: alternative slaughter methods and the meat paradox
Authors: Bayer Elisa , Busch Gesa , Spiller Achim , Kühl Sarah 
Published: August 2023

PurposeThe purpose of this study is to investigate consumers' attitudes towards alternative slaughter methods (ASMs). ASMs present more animal-friendly and stress-free slaughter practices. However, these practices are not yet widespread due to strict regulations, high labor efforts and costs. Therefore, the market for meat products from ASMs is still small, and less is known about consumers' awareness, assessment and willingness to pay (WTP) for these products.Design/methodology/approachThis study aims to close the research gap using a standardized and representative online survey among 1,604 German participants. To identify target groups for these kinds of meat products, a factor and cluster analysis was conducted.FindingsThe results show that ASMs are not widely known among consumers. Overall, participants evaluated ASMs positively, but about 1/3 of the participants stated to also have concerns related more to hygiene than to animal welfare issues. The cluster analysis reveals two out of four clusters found that are interested in ASMs. These clusters are characterized by high trust in small butcheries and organic meat consumption.Originality/valueThe slaughtering sector has hardly been examined from an economic point of view in the animal welfare debate so far. This study identifies potential target groups for products originating from ASMs based on possible consumption drivers and barriers. Therewith, products from particular animal welfare friendly slaughter methods can be promoted purposefully to suitable target groups.
A paradoxical perspective on subsidiary autonomy and MNE entrepreneurial initiative support: uncovering the role of organizational complexity and external embeddedness
Authors: Raziq Muhammad Mustafa 
Published: August 2023

PurposeThis study examines the relationship between subsidiary autonomy and the MNE subsidiary initiative collaboration (i.e. entrepreneurial initiative resource support, the subsidiary seeks and receives from the MNE). It proposes some underlying mechanisms as external embeddedness, and MNE organizational structures to explain the relationship between subsidiary autonomy and the MNE subsidiary initiative collaboration. The study draws on paradox theory arguing how at both the subsidiary and the parent MNE levels certain paradoxes are handled.Design/methodology/approachSurvey data are collected in a time-lagged fashion from 429 foreign subsidiaries in New Zealand. Data are analyzed using structural equation modeling.FindingsResults show that the relationship between subsidiary autonomy and the receipt of MNE resource support for initiatives is positive, and this is more likely the case where the subsidiary is managed under simple structures (i.e. subsidiary reports to corporate headquarters, regional headquarters or mandated units) rather than complex structures (i.e. a matrix or a network). Furthermore, an increase in subsidiary autonomy positively influences MNE initiative resource-seeking, and this is more likely the case where the subsidiary is less embedded externally.Originality/valueThe study is one of the first of studies that has applied paradox theory to MNE–subsidiary relationships regarding autonomy and MNE collaboration on initiatives. The study extends research on MNE–subsidiary collaboration on subsidiary initiatives as existing research is limited on this domain. The study contributes by showing how external embeddedness, and the complexity of organizational structures determine the relationship between subsidiary autonomy and MNE subsidiary initiative collaboration.
Thermodynamical interactions in a micropolar magneto-thermoelastic medium with photothermal effect
Authors: Jatain Sohit , Deswal Sunita , Kalkal Kapil Kumar 
Published: August 2023

Purpose
The purpose of this paper is to establish a two-dimensional model of Green–Lindsay theory for micropolar magneto-thermoelastic medium to study the photothermal effect. The model is used to study the coupling between elastic waves and plasma waves generated due to thermal changes in a micropolar elastic medium.

Design/methodology/approach
Normal mode analysis is used to obtain the analytical solutions of the governing equations.

Findings
Effects of magnetic field, micropolarity, photothermal and time are highlighted on various physical fields such as stresses, temperature, displacement and carrier density. The above physical fields also conform to the boundary conditions. It is further observed that all the physical quantities become zero outside some bounded region of space, thus confirming the notion of generalized theory of thermoelasticity.

Originality/value
The values of physical fields are computed numerically using MATLAB software considering material constants for silicon. Furthermore, the effects are depicted graphically and analyzed accordingly. The study is valuable for the analysis of thermoelastic problems involving magnetic field, micropolarity and elastic deformations.
Integration of the technology acceptance model and the information systems success model in the analysis of Moodle's satisfaction and continuity of use
Authors: Legramante Douglas , Azevedo Ana , Azevedo Jose Manuel 
Published: August 2023

PurposeThis paper aims to analyse the factors that influence the satisfaction and intention of continuity of use, of teachers and students, regarding using Moodle in undergraduate courses in one Campus at the Federal Institute of Rondônia in Brazil. The starting point was an integration of DeLone and McLean's Information Systems Success Model (ISSM) with Davis' Technology Acceptance Model (TAM).Design/methodology/approachA quantitative research approach was adopted. After the definition of the hypotheses, data were collected through self-administered questionnaires. The questionnaires were designed to measure the five constructs: Quality of Information (QI), Perceived Ease of Use (PEOU), Perceived Usefulness (PU), User Satisfaction (US) and Behavioural Intention to use (BI) that make up the conceptual model of the study. The data were analysed based on 144 valid questionnaires. The technique of maximum likelihood estimation was adopted in the data analysis through structural equation modelling (SEM).FindingsThe results confirmed six of the nine hypothesised relationships. QI positively impacts PEOU and US. PEOU positively impacts PU, which in turn positively impacts US and BI. Similarly, US positively impacts Moodle's BI. It was also evidenced that PU is the strongest predictor of US.Practical implicationsThese results can help educational institutions, managers, administrators and designers of e-learning systems to develop strategies to increase Moodle's user satisfaction.Originality/valueThis study provides insights into the perception of students and teachers regarding the use of Moodle. A model that integrates constructs from two models widely used in research related to e-learning (TAM and ISSM) was used in a developing country context. This is important, given cultural differences and social idiosyncrasies in different contexts, particularly in an educational institution in the Amazonia region in northern Brazil.
How do factors of brand-related behavior (brand loyalty, brand relevance in category, brand schematicity) impact consumers’ alcoholic drink purchases?
Authors: Temesi Ágoston , Lakner Zoltán , Unger-Plasek Brigitta 
Published: August 2023

Purpose
This study investigated the factors of brand-related behavior, such as brand schematicity (BS), brand relevance in category (BRiC) and brand loyalty (BL), to clarify how they influence customer purchasing behavior regarding alcohol and other beverages. This study aims to provide insights that may benefit corporate and regulatory sectors regarding brand-related customer behavior and increases/decreases in alcoholic beverage purchases.

Design/methodology/approach
This study included a sample of 501 Hungarian participants, representative of the population in many respects. The author constructed a model using partial least squares structural equation modeling with data collected from internationally validated scales.

Findings
The findings of this study reveal that BL or BRiC do not positively and directly influence purchase frequency in the beer, wine and pálinka categories; however, their purchase frequency is significantly and positively influenced by BS. Additionally, the degree of BS was somewhat above average for alcoholic beverages compared to nonalcoholic beverages; it was also slightly higher for beer than for wine and pálinka.

Originality/value
To the best of the authors’ knowledge, this is the first study to examine the three brand-related factors of customer behavior, analyze their connections and clarify their effects on alcoholic beverage purchases. BS is a relatively new factor; to the best of the authors’ knowledge, no other study to date has measured the extent of BS and its association with beverage-related customer behaviors. Future studies can compare this study’s findings on the level of BS for eight alcoholic and nonalcoholic beverages. To the best of the authors’ knowledge, this study is also the first to investigate brand-related customer behavior regarding pálinka.
Personal initiative, risk-taking, creativity and opportunity discovery among students
Authors: Junça-Silva Ana , Duarte Henrique , Santos Susana C. 
Published: August 2023

Purpose
Discovering opportunities is a key entrepreneurship competence for those who want to start their own business and who choose to enter the workforce. In this study, the authors focus on the antecedents of the ability to discover entrepreneurial opportunities by uncovering how and when students' personal initiative (Frese and Fay, 2001) leads to an increase in this key competency. The purpose of this study was to examine the role of risk-taking and creativity in the interplay between personal initiative and opportunity discovery competencies among university students.

Design/methodology/approach
Data were collected with a self-assessment tool in two moments in time, using a sample of 103 university students from Portugal enrolled in an entrepreneurship course. The authors measured personal initiative and entrepreneurial risk-taking at the beginning of the entrepreneurship course (Time 1). Two months later (Time 2), by the end of an entrepreneurship course, the authors measured creativity and opportunity discovery abilities.

Findings
The results of this study showed that risk-taking mediates the effect of personal initiative on opportunity discovery and that creativity interacts with risk-taking and opportunity discovery. Specifically, the authors found that the relationship between entrepreneurial risk-taking and opportunity discovery is positive and statistically significant when students display average or above-average creativity. The indirect effect of the personal initiative on opportunity discovery through entrepreneurial risk-taking seems to increase when the student's creativity increases, as the index of moderated mediation is positive.

Research limitations/implications
As with all studies, there are limitations to work of this study. First, data of this study is restricted to a sample of students from Portugal. As such, the authors should be careful about generalizations concerning students from other cultural settings; entrepreneurship competencies can differ across countries. Second, the findings of the present study are based on students’ self-reports regarding their own entrepreneurship competencies.

Originality/value
This work can inspire entrepreneurship educators to look at the entrepreneurship competencies models holistically and inspire future work to explore the relationship patterns between entrepreneurial competencies.
Lost archives and found voices: reconstructing the marketing history of medical marijuana in Austria-Hungary
Authors: Stojan Jure 
Published: August 2023

Purpose
The purpose of this paper is to reconstruct the marketing history of medical marijuana cigarettes in the past three decades of Austria-Hungary.

Design/methodology/approach
This paper constructs an analytical narrative based on information scattered in historical periodicals.

Findings
Towards the end of Habsburg rule, two Ljubljana-based pharmacists, the Trnkóczy brothers, managed to establish themselves as monopolistic suppliers of pre-rolled medical marijuana cigarettes for the entire Austrian part of the dual monarchy. Garnering the support of the regional Carniolan Government, Julius von Trnkóczy successfully argued his wares were not affected by the prohibition passed against imported French medicinal cigarettes. This happened despite medical opposition, suggesting that Trnkóczys could only operate this business because of their elevated social status. In the past decade of the 19th century, Ubald von Trnkóczy took advantage of newly loosened regulation to obtain an official permit by the royal-imperial government in Vienna. This was followed, in late 1909, by an advertising campaign covering mass media throughout the empire. This was enabled, amongst others, by a cutting down on medicinal claims. Their declining price is further indication that the cigarettes were mass marketed, especially as their core ingredient, cannabis, underwent price inflation.

Research limitations/implications
Because of its later illegality, the research subject was for a long time considered embarrassing, leading to an absence of retrievable documents. Missing archival sources are thus a major limitation, but one which can be overcome by the concurrent reading of historical periodicals – ranging from mass-market newspapers to specialist journals and legal texts. This paper has implications for 21st-century challenges in the marketing of newly legalized medical marijuana.

Originality/value
This paper discusses the marketing history of cannabis, a drug rarely discussed in historical literature outside its medical and regulatory context, and reconstructs previously forgotten case histories.
SMEs’ intangible resources and their effects on export performance: a study on Malaysian halal F&B sector
Authors: Ahmad-Fauzi Nur Rosdiatul Husna , Md Saad Norsafinas 
Published: August 2023

Purpose
The growing demand for halal products has attracted small and large companies looking to secure their market share in the lucrative global halal market. However, it is difficult for resource-constrained firms, such as small and medium enterprises (SMEs), to compete internationally. Therefore, drawing from a resource-based view, this paper aims to examine how intangible resources affect the export performance of Malaysian SMEs exporting halal food and beverages (F&B) products.

Design/methodology/approach
This study used a purposive sampling technique, and respondents were reached out by mail. Out of 517 local SMEs exporting halal-certified F&Bs contacted, 193 firms responded, and only 188 responses were eligible to be used for data analysis. The partial least squares structural equation modelling technique was used to conduct the analysis. The data underwent measurement and structural model evaluation to confirm the hypotheses postulated.

Findings
Based on the data analysis conducted, it was discovered that intangible resources, namely, international orientation and marketing capability, significantly influence the export performance of Malaysian SMEs exporting halal F&B. However, the influence of cultural intelligence on export performance could not be demonstrated.

Originality/value
This paper fills the gap of the need for more attention to SMEs in developing countries, especially in the halal industry. This research paper also contributes to international business and halal studies by promoting an understanding of intangible resources as strategic resources for SMEs to create competitive advantages and elevate their export performance in the emerging global halal market.
Measuring the value of online databases: a case study to validate an ROI model
Authors: Kaba Abdoulaye , El Refae Ghaleb Awad , Eletter Shorouq , Yasmin Tahira 
Published: August 2023

PurposeThe return on investment (ROI) model is a tool used to measure the financial benefits and costs of an investment, in this case, the investment in digital library resources. By applying this model to the AAU digital library resources, the study seeks to determine whether these resources are providing sufficient value for the investment made in them.Design/methodology/approachThe proposed ROI model has two distinct phases and utilizes two different sets of data to calculate the return on investment for a database subscription. In Phase I, the ROI is calculated based on the total number of downloads of full-text articles from the database during the academic year 2019–2020. This information is used to determine the financial returns of the database subscription costs. In Phase II, the ROI is calculated by examining the citations drawn from the Scopus database on a sample of 30 funded research projects for the College of Engineering during the year 2019. These data are used to determine the impact of the database subscription on research output and its contribution to the success of the College of Engineering's research projects. The two phases of the proposed ROI model aim to provide a comprehensive understanding of the value of the database subscription and its impact on both financial returns and research output.FindingsThe findings of the study indicated different results between Phase 1 and Phase 2 of the study. The positive ROI in Phase 1 suggests that the investment in online databases has a good return for the AAU, as they are gaining almost a dollar for every dollar spent. However, the negative ROI in Phase 2 is concerning. It suggests that the investment in the IEEE database is not generating a positive return for the AAU and may even be costing the institution money. Overall, these findings highlight the importance of measuring ROI in academic libraries, particularly in Arab countries where resources may be limited. By understanding the impact of library investments on institutional outcomes, libraries can make informed decisions about where to allocate their resources and how to optimize their services to best serve their communities.Research limitations/implicationsThe findings of the current study were based on data collected from a specific sample, therefore, the findings may not be generalized to other academic libraries. A similar study with larger and more diverse samples can help to validate and extend the results of this study.Originality/valueThe findings of the study provide evidence that the proposed ROI model can be effectively applied in Arab countries and academic libraries in the Arab world, this could encourage more institutions in the region to adopt this model for evaluating their investments and projects. The study may also guide how to adapt the model to the specific cultural and organizational contexts of Arab countries.
