The purpose of this study was to investigate trends in undergraduate enrollment, graduation, and employment in Ethiopia. It looked at data from the past 20 years of enrollment and graduation, as well as the 15 years of unemployment trends. For enrollment, we used the ARIMA(0,1,0) model, for graduation, the Holt-Winter model, and unemployment, the Simple model. Results showed that enrollment rates increased dramatically, but graduation rates remained constant. Besides, enrollment is expected to continue rising, while graduation rates are expected to fall. On the other hand, between 1999 and 2018, the overall unemployment trend declined. Yet, between 2009 and 2018 the unemployment trends stayed stable. According to the findings, for the next ten years, higher education enrollment and graduation will continue. Nevertheless, it is shown the diminishing demand for jobs in the labor market. As part of improving the existing realities of higher education, the study suggests reconsidering job-driven policy formulation, strengthening higher education-labor market alignment, controlling higher education expansion, and sustaining the development qualification systems.

Native Americans are the single most underrepresented racial group in American higher education today; those enrolled in college are also disproportionately first-generation students. In order to help universities attract and retain Native American students, this study utilizes the four R’s of indigenous research to document the motivations of first-generation Native American students to attend and remain at a mid-sized public university in the northwest. Student participants report that social and cultural support were key factors in their decisions to attend and remain at their institution. Implications of these findings are discussed, and recommendations are made to higher education institutions seeking to attract and retain Native American students.

Student mobility is one of the most important indicators to reflect institutional internationalization in a sustainable higher education system. While student mobility issues have been addressed persistently, the phenomenon is rarely discussed in association with higher education expansion. Since higher education sustainable development has received much scholarly attention, monitoring student mobility flows to adjust international strategies is necessary. This study explored practical approaches to detect student mobility flows in the process of higher education expansion. Targeting Taiwan’s higher education system as an example, we addressed the topic of system expansion and the core issues of student mobility. Target series data were collected from 1950 to 2021, including higher education enrollment, gross enrollment ratio (GER), and number of inbound and outbound students. The data were transformed with index formats, for example enrollment increasing ratio (IR) and net flow ratio. The cross-correlation function (CCF) and autoregressive integrated moving average (ARIMA) were used to determine the correlations of the series data and their future trends. The findings suggested that the effect of system expansion, with GER and IR, might influence the mobility ratios significantly in the process of higher education expansion. This study confirmed that the time series approaches work well in detecting the phenomena of higher education expansion and their effects on student mobility flows in the future.

Ensuring equal access to affordable higher education for women and men has become a crucial target of UNESCO’s SDG4-Education 2030. Currently, about one-third of the world's college-age population participates in higher education, while the gender disparity persists in various systems. This study employed GDP per capita, gross enrollment ratio (GER), and the gender parity index (GPI) to demonstrate how the education systems have expanded resulting in the transformation of gender parity. We selected Japan, Korea, Taiwan, and the UK as research targets using a cross-correlation function and trend analysis to detect concurrent relationships and future trends with GDP per capita, GER, and GPI. The findings suggest Japan, Korea, and the UK continue to show gender disparity and need to respond to this issue in their policy intervention for SDG4-Education 2030. The results reveal a potential problem in the UK when GPI growth might become unlimited with females dominated. This study suggests the higher education expansion phenomenon and gender diversity in mass and universal systems can be detected by the trend analysis with GDP per capita, GER, and GPI in different settings. The design of the study provides an example to explore the gender diversity patterns in higher education systems for sustainable development.

Clinical trials often involve new substances characterized or developed for a specific pathology or class of pathologies. At other times, a clinical trial is observational; in other words, a known substance has a range of effects on a given cohort of subjects. The types of trials are different and complex, and often, the young clinical novice and the inexperienced researcher cannot correctly evaluate how to follow. In this paper, we want to create a mini guide for beginners in clinical trials and provide elements to design a clinical trial. We intend to point out where to find the materials and how to adjust even in the absence of sponsors so that even the most inexperienced and without means researcher can get an idea of the complexity of the process and deal with it in the right way. We do not presume to be exhaustive, nor claim to value all the elements, but instead realize a checklist. With this spirit, starting to talk about the experimental phases of the drug and ending with the clinical trial, we want to help those who face this problematic "world."
