This study employed the autoregressive distributed lag (ARDL) model to investigate the short-run and long-run effects of each exogenous variable on rice production. In this research work, auto regressive integrated moving average (ARIMA) and hybrid ARIMA-(general autoregressive conditional heteroskedastic) GRACH were used to forecast rice production in Bangladesh from 1983 to 2030. The parameters of price of rice, area irrigated by different improved methods, area, and fertilizer were found to have a significant and positive impact on rice production in this study, both in the short run and the long run, according to the ARDL model. According to the lowest Root Mean Squared Error, Mean Absolute Error and Theil Inequality Coefficient criteria, the linear hybrid ARIMA (11, 1, 11)–EGARCH (1, 1)–M model performed better in predicting the rice production in Bangladesh.</p> <p>IUBAT Review—A Multidisciplinary Academic Journal, 5 (1): 1-14</p> 2022-12-29T00:00:00+00:00 Copyright (c) 2022 Rehana Parvin Adaptation of Health-Specific Self-Efficacy Scales for use in Bangladesh 2023-02-28T07:01:09+00:00 Mallika De Saiyeda Asea Asha <p>The aim of the present study was to adapt a ‘Health-Specific Self-Efficacy Scales (HSSES)’ for use in Bangladesh. For this purpose, 155 respondents (age range 18 to 42 years) were selected using convenient sampling technique from different departments (students, facultiesand stuff) of IUBAT University. The scales were adapted following five steps such as ensuring construct equivalence, forward translation, focus group discussion, back translation as well as a pilot study. The findings demonstrated that the Bangla Version of 'Health-Specific Self-Efficacy Scales' has sound reliability [Cronbach Alpha 0.79 (‘Nutrition Self-Efficacy (NSE)’ 0.84, ‘Physical Exercise Self-efficacy (PESE)’ 0.76,‘Alcohol Resistance Self-efficacy (ARSE)’ 0.82), Split-half reliability 0.73 (Spearman-Brown) and 0.76 (Guttman method), test-retest reliability 0.67] and satisfactory validity. These results exhibit that Health-Specific Self-Efficacy Scales (‘NSE’, ‘PESE’ and ‘ARSE’) are reliable and valid instruments for assessing nutrition, physical exercise and alcohol resistance-related self believes as well as health consciousness. Furthermore, this study uncovers the opportunity for further health-related research projects in Bangladesh.</p> <p>IUBAT Review—A Multidisciplinary Academic Journal, 5 (1): 15-25</p> 2022-12-29T00:00:00+00:00 Copyright (c) 2022 Mallika De, Saiyeda Asea Asha Examining the Nexus between External Debt and Economic Growth in Bangladesh: An ARDL-ECM Approach 2023-02-28T07:01:10+00:00 Imtiaz Ahmed Mobasshir Anjum Md Mahmudul Hasan Sahabuddin Ahmed Seikdear <p>This paper aims to examine the nexus between external debt and economic growth in Bangladesh for periods ranging from 1973 to 2019. Time-series econometric techniques of Autoregressive Distributed Lag Model (ARDL) and Error Correction Method (ECM) are utilized in empirical analysis to investigate whether short-run and long-run dynamics exist between external debt and the growth of Bangladesh. Findings derived from the analysis reveal a long-run association between external debt and Bangladesh's economic growth. The error correction method also points out long-run adjustment if any disequilibrium arises in a period in the short run. The study recommends maintaining a stable position of overseas debt and ensuring compatible investment conditions for domestic and foreign investors.</p> <p>IUBAT Review—A Multidisciplinary Academic Journal, 5 (1): 26-34</p> 2022-12-29T00:00:00+00:00 Copyright (c) 2022 Imtiaz Ahmed, Mobasshir Anjum, Md Mahmudul Hasan, Sahabuddin Ahmed Seikdear Sin and Punishment in The Scarlet Letter: A Feminist Perspective 2023-02-28T07:01:12+00:00 Sheikh Saifullah Ahmed Kazi Imran Hossain <p>In this article, Nathaniel Hawthorne’s The Scarlet Letter, which is set in the Puritan society of Boston in the middle of the seventeenth century, is subjected to a close and in-depth analysis. Within the realm of feminist studies, one of the most important topics to discuss is the way in which female characters are portrayed in works of fiction. The female protagonist of the novel is Hester Prynne whose sin and receiving punishment and, therefore, her self-development without being reliant on her male counterparts for livelihood, with ups and downs in the patriarchal society and being ostracized are taken into account for this study. The objective of this study is to demonstrate that the narrative does not adhere to the antiquated norms of patriarchal heritage in its depiction of women; rather, it is a protest against the constraints that society places on women at the time it was written. A qualitative content analysis method is adopted to investigate the representation of female characters in this narrative. The portrayal of Hester Prynne and Pearl is explored through the lens of feminist stance for the possibility that it challenges conventional practices. It clarifies the author’s stance in the patriarchal setting. Thus, this study conducts a rigorous analysis of the traditional patriarchal and stereotypical portrayals of the woman in literature and suggests reconsideration of the long-held patriarchal practices of representing women in fiction.</p> <p>IUBAT Review—A Multidisciplinary Academic Journal, 5 (1): 35-43</p> 2022-12-29T00:00:00+00:00 Copyright (c) 2022 Sheikh Saifullah Ahmed, Kazi Imran Hossain COVID-19's Impact on Human Resource Management strategy: A Review Study 2023-02-28T07:01:13+00:00 Reefat Arefin Khan <p>The COVID-19 outbreak poses challenges for organizations as many external environmental objects are changing. It raises the importance of Human resource management (HRM) strategy as the HRM strategy works to motivate the employees and develops the workforce. The methodology used in this research is general literature review which shows the analysis of most recent articles, research papers and scientific study. The aim of this research is to identify HRM activities during COVID-19 pandemic and the way HRM develops their strategy to match their strategy with the organizational strategy to shove the business towards their goals. In the light of COVID-19, employee anxiety is increasing due to the deterioration of economic conditions, as well as an increase in the unemployment rate, and the number of businesses is congested. COVID-19 pandemic situation modify the Organizational strategy and HR strategy, and organizational critical goals are transform by COVID-19 pandemic situation.</p> <p>IUBAT Review—A Multidisciplinary Academic Journal, 5 (1): 44-53</p> 2022-12-29T00:00:00+00:00 Copyright (c) 2022 Reefat Arefin Khan A Review on Partial Replacement of Cement in Concrete by Three Supplementary Materials 2023-02-28T07:01:14+00:00 Md Abdul Basit Md Monirul Islam Md Syekat Ahmed Suvash Chandra Paul Noor Md Sadiqul Hasan <p>This paper explores the consequence of replacing cement by fly ash, rice husk ash and lime in concrete. For widespread use of these supplementary materials, it is important to ensure the quality of resultant concrete. In this paper literature related with workability, density, compressive strength, flexural strength and splitting tensile strength are analyzed. Main advantages and drawbacks of using these materials in terms of engineering properties are mentioned. Another aim of this review is to identify major research needed in this field to use these materials worldwide given that concrete is the most extensively used man-made material.</p> <p>IUBAT Review—A Multidisciplinary Academic Journal, 5 (1): 54-67</p> 2022-12-29T00:00:00+00:00 Copyright (c) 2022 Md Abdul Basit, Md Monirul Islam, Md Syekat Ahmed, Suvash Chandra Paul, Noor Md Sadiqul Hasan Effective Teaching in Constructivism: A Case of Teaching Discrete Mathematics for Undergraduate Students 2023-02-28T07:01:16+00:00 Rajib Lochan Das Khandoker Saif Uddin <p>Looking for an effective teaching method to ensure better learning of students is a common and longstanding phenomenon. Several learning theories evolved over the course of time. The constructivist approach to teaching learning is often found as an effective one that runs in a student-centred environment where participatory and active learning is nurtured. In this case study, the constructivist approach was employed in teaching discrete mathematics to Bachelor of Computer Science and engineering students at a non-government university in Bangladesh. The study was quasi-experimental involving a non-probability convenient sampling technique. A total of 372 students were invited to attend pre- and post-tests in online mode on each of the 6 chapters throughout the four consecutive semesters. Attending each of the tests was not a mandatory requirement of the students for the course. Collected scores from the 12 tests were statistically analysed to draw a meaningful conclusion based on the discussions over the analyses of findings. Limitations, implications, and direction to future research are also brought up. The results of this study will help the institutional authority, teachers, and students to make an effective plan by adopting constructivist teaching learning not only for mathematics education but also for other similar subjects.</p> <p>IUBAT Review—A Multidisciplinary Academic Journal, 5 (1): 68-76</p> 2022-12-29T00:00:00+00:00 Copyright (c) 2022 Rajib Lochan Das, Khandoker Saif Uddin Factors that Influence Followers to Be a Future Ethical Leader 2023-02-28T07:01:18+00:00 Hasanuzzaman Tushar Selina Nargis Shaikh Sabbir Ahmed Waliullah <p>This literature review study connects such elements to relevant ethical theories (such as utilitarianism, libertarianism, Kant's ethical theory, and fairness and justice), focusing on the characteristics that empower people to become future ethical leaders. This research attempts to investigate the idea of ethical leadership, the significance of ethical leadership in an organization, determining components to be an ethical leader, and strategies to turn followers into ethical leaders from the intersection of the literature reviews on ethics and leadership. A major research question directed the study: what are the factors that inspire followers to become future ethical leaders? Based on data found from the various books and articles, different databases and a list of keywords used during the search. According to the research outcomes, two key influences—(a) an individual's moral worldview and (b) organizational culture and ethics—can motivate followers to become moral leaders. Family influences, religious conviction, educational institutions, peer influences, and culture have an impact on an individual's moral philosophy. Besides organizational culture and ethics consists of code of conduct, work-life balance, recruitment procedure, compensation plan, role model, training, and further development. The influencing factors were discussed and recommended further research area. The relevant elements were explored, and further research area was suggested.</p> <p>IUBAT Review—A Multidisciplinary Academic Journal, 5 (1): 77-88</p> 2022-12-29T00:00:00+00:00 Copyright (c) 2022 Hasanuzzaman Tushar, Selina Nargis, Shaikh Sabbir Ahmed Waliullah The Role of Oral Presentations in Developing Undergraduate Learners' Speaking Skills in Bangladesh 2023-02-28T07:01:19+00:00 Firoz Akanda Lulu Al Marzan Md Sadekul Islam <p>Developing speaking skills is considered an important goal for tertiary-level students in Bangladesh. Learning oral presentation techniques can lead learners to communicative competency, especially speaking competence. This paper explores the role of oral presentations in developing undergraduate EFL (English as a foreign language) learners' speaking skills in selected private universities in Bangladesh. The study followed a quantitative method and collected data from one hundred thirty-five EFL tertiary-level students. The findings show that oral presentations have positive impacts on learners' motivation and enhance their speaking skills. At the same time, the findings also indicate that there are a number of potential factors that hinder the learners' oral delivery which include their lack of motivation, limited vocabulary, anxiety, and fear. The study results have implications for instructional design and delivery at the tertiary level in Bangladesh as well as in other similar contexts.</p> <p>IUBAT Review—A Multidisciplinary Academic Journal, 5 (1): 89-99</p> 2022-12-29T00:00:00+00:00 Copyright (c) 2022 Firoz Akanda, Lulu Al Marzan, Md Sadekul Islam
