As they navigate the social and academic expectations of a new college, transfer students commonly suffer “transfer shock,” or a sudden drop in GPA. However, little is known about why some students suffer transfer shock, why some bounce back, and the consequences in terms of student retention. This analysis of over 25,000 transfer students (N = 25,000) at a large flagship university finds an average first-term drop of −0.30 GPA points, but the impact of this shock on student departure is dependent on initial GPA, the steepness of the drop, and the student's ability to rebound in their second term. To support transfer student retention and graduation, sending institutions can help students to pre-appraise the potential setback as normal and temporary, while receiving institutions can provide proactive outreach to transfers who arrive with a GPA below 2.0 or who suffer a GPA drop steeper than −0.50 in their first term.
Universities increasingly require students to enroll in diversity coursework, which is positively associated with a range of academic and social outcomes and psychological wellbeing. However, these courses can be challenging for both students and faculty to navigate. For institutions to effectively engage diversity on campus, attention must be paid to pedagogical and curricular transformation-not only in stand-alone diversity classes, but in major-specific coursework as well. This conceptual paper explores the benefits of using open educational resources (OER) and open educational practices (OEP), in combination with the Hewlett Foundation's Deeper Learning framework and empathic scaffolding, in promot-
In rural areas and isolated regions of the world, it is often difficult to obtain reliable access to electricity. A solution often exploited is the use of diesel generators to power homes but that has its negative effects on climate change. In this study, an alternative solution is being investigated, which involves the use of water turbines. For low head applications such as rivers, hydrokinetic turbines are used to harness the kinetic energy in rivers. There are two types of hydrokinetic turbines: horizontal and vertical axis water turbines. The turbine studied in this paper is the Darrieus type vertical axis water turbine (VAWT) which has three straight blades. Darrieus type VAWT primarily use lift forces to operate. Advantages of vertical axis water turbines are simple construction, low cost, and being able to self-orient. However, the Darrieus VAWT has several disadvantages like self-starting problem, low coefficient of performance, shaking, debris accumulation, and cavitation.
In this study, the effect of using thermoplastic polyurethane blades with varying levels of flexibility have been investigated to remedy the self-starting problem. For blade profile, S1046 airfoil is selected. 3-D numerical models were created by using time-accurate Reynolds-averaged Navier Stokes (RANS) commercial solver (ANSYS Fluent 2019 R3). Experimental results show that turbine with lower blade hardness starts to rotate at 0.34m/s while the turbine with higher blade hardness experiences rotation at 0.51m/s.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
