Analysis of Student's Academic Achievement in Music of Visayas State University System

Parental factors impact students’ self-concept and academic performance during the pandemic. Thus, this study determined the students’ self-concept and academic performance and the parental factors related to it. The research design was descriptive-correlational, and 500 nonrandom college students in West Philippines participated in the study. Researcher-made instruments were used, which were subjected to reliability and validity evaluation. Data were collected online from June 2021 to July 2022 and were analyzed using descriptive (frequency counts and percentage) and inferential statistics (Spearman correlation). Results revealed a positive self-concept and satisfactory academic performance among the students. Besides, parental factors such as educational attainment and school/classroom involvement are significantly related to self-concept and academic performance. Further, self-concept is significantly associated with academic performance. This shows that some parental factors are vital in developing the student’s self-beliefs and supporting their studies and academic endeavors amid the COVID-19 pandemic. Future studies may consider more factors related to academic achievement and self-concept. Other researchers may find the mediation or moderation effect of self-concept between parental factors and students’ scholastic achievement. KEYWORDS: academic performance, COVID-19 pandemic, distance learning, higher education, parental factors, self-concept

Analytical Solutions for Boundary Layer Flows of Differential Type Fluids

The study of unsteady flow and heat transfer of non-Newtonian fluids over stretching surface is very important and serves a widespread variety of practical applications in industry. In this thesis, a theoretical study is undertaken into fluid flow and heat transfer due to stretching surface for the non-Newtonian second grade fluid. The second grade fluid considered in the current analysis is a subclass of differential type nonlinear fluid. Additionally, second grade liquid is capable to explore the features of normal stress impacts. More specifically, this thesis is concerned with study of the unsteady boundary layer flow and heat transfer characteristics for a second grade liquid over stretching surface and considered different problems of practical interest. The problems include, the forced convective heat transfer over stretching surface assuming different situations including nanolfuid, chemical processes and Cattaneo-Christov heat and mass flux relations. The transformed boundary layer equations are solved analytically by the homotopy analysis method. The analytical solutions have been computed for the velocity, temperature and concentration distributions. The effects of important physical parameters are presented graphically in order to visualize the impact of these parameters. The effects of non-dimensional parameters on the temperature, concentration and local Nusselt are elaborated through graphs and tables. The effect of non-dimensional parameters on the local Nusselt is discussed by using graphs. The obtained results reveal that the temperature profile diminishes for augmented values of the thermal relaxation parameter. In addition to this, it has come to the observation that the liquid temperature is higher for classical Fourier''s law when compared to non- Fourier''s law. It is estimated from the plots that the concentration of the second grade nanoliquid drops as the Brownian motion parameter increases while the reverse trend is detected for the thermophoresis parameter. Moreover, it is perceived from the results that the temperature of the second grade nanoliquid declines as unsteadiness parameter enhances.
