Extensions of the Newsvendor Model – Incorporating Real Life Scenarios Using Decision Analytics
Get PDFDecision Analysis is an important topic in the field of Operations Research. This article is a result of discussing the well-known newsvendor model in the classroom over many semesters. We present the newsvendor model in our MBA class but go beyond what textbooks provide. We extend this model by incorporating two specific real-life scenarios. We create the modified payoff table using spreadsheets. We then consider what-if scenarios and perform sensitivity analysis using the Data Table command in Excel. Important concepts like backordering/late shipment, cost of lost customer goodwill, and clearance pricing are discussed. The discussion of these concepts is extremely valuable even without spreadsheets
Greenhouse Gas Emission – A Perspective
Get PDFClimate change is an ongoing discussion especially concerning greenhouse gases and their emission. Greenhouse gases and emission are terms used in newspapers, television and much of today’s common press often without an explanation of the terms’ definition or meaning. Discussing these terms classifies their genesis together with greenhouse emission sources and creation. Concerns and consequences of greenhouse gas emissions, together with current reporting guidelines, are summarized to provide an understanding of the enormity of the issues. A sample of corporations’ existing goals, aims, and projects illustrate how the entities plan to meet their net-zero greenhouse gas emission promises illustrate efforts underway to harness environmental contamination
Challenges for Successful Transfer From Community to Bachelor’s Colleges: Views of Staff and Faculty With Transfer Responsibilities
Get PDFStaff and faculty have influential roles in the success of students transferring from associate’s- to bachelor’s-degree programs (vertical transfer students). Our survey compared the reported views on transfer of 607 staff and faculty with transfer responsibilities in associate’s or bachelor’s programs at 19 City University of New York colleges. The findings included: (1) Staff reported feeling more confident in their responsibilities than did faculty. (2) Participants working with associate’s-degree students were more likely to report their colleges had sufficient transfer-service resources. (3) Associate’s-degree faculty were the least likely participant group to respond that the biggest barrier to the transfer process was GPA decline (transfer shock), and the most likely that it was credit transfer, whereas for bachelor’s-degree faculty, it was the reverse. These findings can inform policy and practice. For example, to work together towards a common goal of transfer student success and higher education equity, faculty may need more support in performing transfer-related duties and bridging their differing views across college sectors
Using the Moodle Platform in the English Reading Comprehension of Students at a Higher Education Military School
Get PDFThe use of virtual educational platforms has experienced a remarkable increase in the academic field, offering innovative tools that enhance the quality of teaching and the learning process. The objective of the research was to determine the influence of the use of the Moodle platform on the English reading comprehension of students in a higher education military school. The study was a basic, causal correlational, non-experimental, cross-sectional design. The population included 1.341 students from a military school in Lima, Peru, and the sample consisted of 300 students selected by random probability sampling. The results showed that the use of the Moodle platform has a regular performance (45.7%), while English reading comprehension is in process (39.7%). It was concluded that the use of the Moodle platform has a significant influence on English reading comprehension, being this influence high (Nagelkerke’s R2 = 0.808)

Notably, author Bell R emerged as a prominent figure in this field. By scrutinizing the articles, it was also evident that keywords such as entrepreneurship education, business education, entrepreneurship, entrepreneurial intention, and entrepreneurial education hold significance within the domain. The insights gleaned from this analysis suggest valuable strategic information to researchers and aid them in formulating and mapping out future studies in entrepreneurship education
Implementation of Service-Learning in Madrid Primary Schools
Get PDFService-Learning (SL) is an experiential educational approach that engages students in solving real-world problems within their local environments, thereby enhancing both learning and community well-being. This study conducts a quantitative analysis of SL implementation in primary education across the Community of Madrid, using data from questionnaires distributed among local schools. From 262 responses, descriptive statistics and non-parametric tests were applied. The findings highlight that, despite the recognized benefits of SL and the interest from many teachers in adopting this approach, there is a significant lack of adequate training during both initial teacher training and ongoing professional development. SL projects, though infrequent, have been implemented across various grades, with a higher occurrence in the later stages, and have covered all subjects, most notably Social and Civic Values. However, the overall implementation of the SL methodology remains sparse in the Community of Madrid

Health Care REIT Returns & Covid-19: A Note
Get PDFThis study tests for pricing efficiency in Healthcare Real Estate Investment Trusts (REITs) surrounding the Covid-19 pandemic. Fractal analysis is used to ascertain whether any persistence or anti-persistence in returns can be observed over the “pre-Covid” and “Covid/post-Covid” periods for the 15 healthcare equity REITs included in the FTSE NAREIT US Real Estate Index. The results point to weak form efficiency during the complete sample period with some exceptions. A relative stability in Hurst exponents exists across the sub-periods for several of the REITs. However, there is evidence that many other REITs series switch from being anti-persistent to persistent, a result consistent with possible herding behavior. Some very limited evidence is found of series switching from being persistent to anti-persistent, consistent with investor overreaction for these REITs. Overall, inefficient pricing is seen in a limited number of cases, but there is a strong suggestion of a possible change like the return dynamic in the latter part of the study period associated with the pandemic
Exploring Financial Performance Disparities: An In-Depth Analysis of Companies Led by Foreign-Born CEOs Versus Non-Foreign-Born CEOs Within the S&P 500
Get PDFThere is an increasing trend for companies to have foreign-born Chief Executive Officers. It was found that 101 companies in the S&P 500 had foreign-born CEOs. The purpose of this paper was to investigate whether companies with foreign-born CEOs exhibited better financial performance.
The study adopted a quantitative approach. We gathered two datasets: one detailing the performance of companies with CEOs born in the United States, and the other delineating the performance of companies with CEOs born outside the United States. We utilized the T-test for the difference of means on these two sets of data. This statistical method allowed us to assess the variations in financial performance metrics between the two groups over a six-year period.
The findings indicate that foreign CEOs consistently outperformed their domestic counterparts across all three studied KPI performance measures from 2018 to 2023. T-tests for the difference of means indicated that these results were statistically significant
Integrating Polyvagal Theory With Agile Project Management
Get PDFThe modern project management environment has become more complex due to various influences. For instance, stress and trauma are recognized as powerful influences on employee behaviors and decision-making. Although past studies have attempted to understand the psychology behind this phenomenon, scarce research has been performed on the influence of the autonomic nervous system on project management outcomes. Accordingly, this paper investigates the underlying nervous system responses that shape project management activities in different organizations. It relies on the Polyvagal Theory to elucidate the neurobiological responses that emerge when project managers are faced with stressful, dangerous or life-threatening situations. Thus, the paper can offer feasible recommendations for optimizing project management outcomes by strengthening the link between the heart, mind, and body
