Electrical/electronics technology education teachers attitude, engagement, and disposition towards actual usage of Mobile learning in higher institutions
Education and Information Technologies, 2020Co-Authors: Taiwo Olabanji Shodipe, Ifeanyi Benedict OhanuAbstract:The conventional teaching methods like the use of demonstration, lecture and project methods in teaching Skilled/Trade subjects is still persistent among higher institutions in Nigeria, therefore, this study examined Electrical/Electronics technology education teachers attitude, engagement and disposition towards actual usage of mobile learning in higher institutions. The sample for the study comprised 418 electrical/electronics technology education teachers using cluster sampling technique to select samples from higher institutions in three states in the geo-political zone. Data analysis was done with exploratory factor analysis and confirmatory factor analysis. The study found out that teacher’s perceived ease of use significantly have positive direct link on actual usage of ML, teacher’s disposition positively linked with perceived ease of use, teacher’s psychological well-being and perceived usefulness positive linked while technical/technology teacher’s training linked negatively with perceived ease of use of ML. Extending TAM robustness, the study affirmed that technical teacher education training and psychological well-being are factors that could influence perceived ease of use and perceived usefulness towards actual usage of mobile learning.

Mild steel and stainless steel welding fumes elicit pro‐inflammatory and pro‐oxidant effects in first trimester trophoblast cells
American journal of reproductive immunology (New York N.Y. : 1989), 2020Co-Authors: Nicole S. Olgun, Anna M. Morris, Lauren N. Bowers, Aleksandr B. Stefaniak, Sherri Friend, Sandra E. Reznik, Stephen S. LeonardAbstract:PROBLEM As more women join the Skilled-Trade workforce, the effects of workplace exposures on pregnancy need to be explored. This study aims to identify the effects of mild steel and stainless steel welding fume exposures on cultured placental trophoblast cells. METHOD OF STUDY Welding fumes (mild steel and stainless steel) were generously donated by Lincoln Electric. Electron microscopy was used to characterize welding fume particle size and the ability of particles to enter extravillous trophoblast cells (HTR-8/SVneo). Cellular viability, free radical production, cytokine production, and ability of cells to maintain invasive properties were analyzed, respectively, by WST-1, electron paramagnetic resonance, DCFH-DA, V-plex MULTI-SPOT assay system, and a matrix gel invasion assay. RESULTS For all three welding fume types, average particle size was

Generating Skilled Self-Employment in Developing Countries: Experimental Evidence from Uganda*
The Quarterly Journal of Economics, 2013Co-Authors: Christopher Blattman, Nathan Fiala, Sebastian MartinezAbstract:We study a government program in Uganda designed to help the poor and unemployed become self-employed artisans, increase incomes, and thus promote social stability. Young adults in Uganda’s conflict-affected north were invited to form groups and submit grant proposals for vocational training and business start-up. Funding was randomly assigned among screened and eligible groups. Treatment groups received unsupervised grants of $382 per member. Grant recipients invest some in skills training but most in tools and materials. After four years, half practice a Skilled Trade. Relative to the control group, the program increases business assets by 57%, work hours by 17%, and earnings by 38%. Many also formalize their enterprises and hire labor. We see no effect, however, on social cohesion, antisocial behavior, or protest. Effects are similar by gender but are qualitatively different for women because they begin poorer (meaning the impact is larger relative to their starting point) and because women’s work and earnings stagnate without the program but take off with it. The patterns we observe are consistent with credit constraints.

Credit constraints, occupational choice and the process of development : long run evidence from cash transfers in Uganda
2013Co-Authors: Christopher Blattman, Nathan Fiala, Sebastian MartinezAbstract:This brief summarizes the results of a gender impact evaluation study, entitled Credit constraints, occupational choice and the process of development : long run evidence from cash transfers in Uganda, conducted in the year 2008 in Uganda. The study observed that poor, unemployed men are commonly associated with social dislocation and unrest, and governments routinely justify employment programs on reducing such risks. Despite huge economic effects, we see little impact on cohesion, aggression, and collective action. The treated youth invest most of the grant in skills and business assets. After four years, they are 65 percent more likely to practice a Skilled Trade, mainly small scale industry. The gains are the largest amongst those with the fewest assets. Women earn higher returns than men compared to control (84 percent for women, 31 percent for men). Funding for the study derived from Uganda Social Action Fund, Spanish Impact Evaluation Fund.
