Program Evaluation of Student-Athlete Academic Support Services Unit Using the Logic Model Evaluation

AbstractThe study utilized the logic model evaluation to ascertain the effectiveness of the Student-Athlete Academic Support Services (SAASS) unit at a NCAA Division I research university located in the Western United States. The logic model evaluation provided a process to determine the extent to which the unit achieved its purpose and outcomes. The logic model evaluation can be tailored to the exact unit based on the short-term and long-term goals of the program. Based on the tenets of flexibility and adaptability, the logic model evaluation was selected as an appropriate tool for the study. Overall, the SAASS unit was perceived to be effective by its key constituent groups. The evaluation highlighted the importance of the athletic academic advisor in keeping students on track to graduation and communicating issues to administrators, coaches, and professors. Recommendations are provided to potentially improve the SAASS unit under study

Determination of structural engineering properties of incoloy 903 and CTX-1 alloys

Tension, notched tension, compression, density, thermal conductivity, and thermal expansion tests were conducted on Incoloy 903 over the temperature range 20 K (-423 F) through 1033 K (1400 F). Fracture toughness tests were performed at room temperature (RT). Creep and rupture tests were conducted at 811 K (1000 F), 922 K (1200 F), and 1033 K (1400 F) for this alloy. Transverse unnotched and notched fatigue tests at R = 0.1 were performed at RT and 922 K (1200 F). For CTX-1 alloy, tension, Charpy V-notch impact, density, thermal conductivity, and thermal expansion tests were conducted over the temperature range 20 K (-423 F) through 1033 K (1400 F). Poisson's ratio was determined at RT, 811 K (1000 F), 922 K (1200 F), and 1033 K (1400 F). Notched tension and compression tests were performed at 20 K (-423 F), RT, and 922 K (1200 F); plane strain fracture toughness tests were conducted at RT, 77 K (-320 F), and 20 K (-423 F). Creep and rupture tests were performed at 811 K (1000 F), 922 K (1200 F), and 1033 K (1400 F); longitudinal unnotched and notched fatigue tests at R = 0.1 were conducted at RT and 922 K (1200 F). Results are presented and discussed

Wild cards, weak signals and prganizational improvisation

This paper addresses the need for reliable action guidelines that can be used by organisations in turbulent environments. Building on current conceptual and empirical research, we suggest an analytical approach for the management of surprising and potentially damaging events. In order to do so we use the wild card management system. Wild cards refer to sudden and unique incidents that can constitute turning points in the evolution of a certain trend or system. As the first of the two components of such a wild card system we advocate a weak signal methodology to take into account those wild cards that can be anticipated by scanning the decision environment. The second component, the nurture of improvisation capabilities, is designed to deal with ongoing crisis. This paper can be seen as part of a broader agenda on how to manage in conditions of continuous but unpredictable change.wild cards, weak signals, improvisation, minimal structures

Hygroscopicity as a Factor in the Thermal Conductivity of Loose-Fill Insulators

There has been constructed a thermal conductivity apparatus of the guarded hot plate type employing a compensatory heating unit and designed to test samples having low values of thermal conductivity. Tests on various types of loose-fill thermal insula· tors reveal that there is a linear increase of thermal conductivity with increased moisture content. Depending upon the particular type of sample under consideration, a hygroscopicity of 20 to 30 per cent by weight completely vitiates the efficacy of loose-fill jnsulation

Polar Dynamics at the Jahn-Teller Transition in Ferroelectric GaV4S8

We present a dielectric spectroscopy study of the polar dynamics linked to the orbitally driven ferroelectric transition in the skyrmion host GaV4S8. By combining THz and MHz-GHz spectroscopy techniques, we succeed in detecting the relaxational dynamics arising from coupled orbital and polar fluctuations in this material and traced its temperature dependence in the paraelectric as well as in the ferroelectric phase. The relaxation time significantly increases when approaching the critical temperature from both sides of the transition. It is natural to assume that these polar fluctuations map the orbital dynamics at the Jahn-Teller transition. Due to the first-order character of the orbital-ordering transition, the relaxation time shows an enormous jump of about five orders of magnitude at the polar and structural phase transition.Comment: 5 pages, 4 figure

Polar and magnetic order in GaV4Se8

In the present work, we provide results from specific heat, magnetic susceptibility, dielectric constant, ac conductivity, and electrical polarization measurements performed on the lacunar spinel GaV4Se8. With decreasing temperature, we observe a transition from the paraelectric and paramagnetic cubic state into a polar, probably ferroelectric state at 42 K followed by magnetic ordering at 18 K. The polar transition is likely driven by the Jahn-Teller effect due to the degeneracy of the V4 cluster orbitals. The excess polarization arising in the magnetic phase indicates considerable magnetoelectric coupling. Overall, the behavior of GaV4Se8 in many respects is similar to that of the skyrmion host GaV4S8, exhibiting a complex interplay of orbital, spin, lattice, and polar degrees of freedom. However, its dielectric behavior at the polar transition markedly differs from that of the Jahn-Teller driven ferroelectric GeV4S8, which can be ascribed to the dissimilar electronic structure of the Ge compound.Comment: 7 pages, 6 figures.
