This study was designed to determine the predictive validity of selected admissions variables used by the University of Kentucky College of Medicine. Data for the study were collected from 586 students admitted to the M.D. program from 1961 to 1968. These students were categorized into one of three groups (Successful [SUCC], Successful with Extended Study [SWES], and Lost to Medicine [LTM]) based upon their performance in medical school. A two-way analysis of variance and the use of a post hoc Scheffé method of multiple comparisons indicated significant differences between the SUCC group and the combined SWES and LTM groups. Therefore, the data revealed the predictive ability of two admissions variables and suggested the need for additional research into the subjective variables used in the admissions process. 相似文献

Throughout his distinguished career of over 40 years, Robin Hochstrasser has made significant contributions to several areas of science in the fields of chemical and biochemical physics. He has been at the forefront and made fundamental contributions to the fields of photochemistry, solid-state chemistry, ultra-fast laser spectroscopies, and protein dynamics. He has been a prolific researcher, producing over 560 publications. His work has been characterized by experts in the fields as “a constant stream of experiments of lasting significance” (J. Phys. Chem. 100 (1996) 11791).Robin began his career in the 1960s using a variety of magnetic and electric field measurements to study crystals at low temperatures to understand spin quantization in solids and electron exchanged-mediated energy transfer. This work, described as a “classic contribution” (J. Phys. Chem. 100 (1996) 11791) was the basis for much of the subsequent experimental and theoretical work on the effect of magnetic fields on molecular spectra and on the measurements of dipole moments.In the late 1970s, Robin recognized the power of laser technology for the study of molecules and soon became a leader in the field investigating solid, gas phase, and condensed phase systems. He developed and applied various ultra-fast laser techniques to study the structure and dynamics of complex molecules in liquid phase, chemical, and biochemical reactions. He made seminal contributions to the development of two-dimensional infrared spectroscopy (2D IR) on a time scale of a picosecond or less. This 2D IR spectroscopy measures coupling between two functional groups in a large molecule and can thus be used to measure distances, as for example, two amide carbonyl groups in a peptide molecule. On the ultra-fast timescale, one application of 2D IR is to gain information on the rate of protein folding and unfolding in solution. Some of Robin's greatest contributions to understanding biomolecules are said to be in the experimental studies on the picosecond and femtosecond dynamics of heme proteins. Using techniques he developed he was able to observe the interactions of oxygen, carbon monoxide, and nitric oxide with hemoglobin inside the protein. 相似文献

College counselors can enhance the development of Native American Indian college students. College counselors need to be aware of traditional Native American Indian values, interpretation of mental health, content and process concerns in counseling, and indigenous healing practices. These areas are discussed, as well as implications for counseling practice. 相似文献

In its various guises the political and economic implications of the spectrum of ideas labelled ‘sustainable development’ have been widely discussed in the media. This research engaged secondary school teachers in the debate concerning the implications for education of the concept of sustainable development. Underpinning this pilot research project is the assumption that teachers, as generally informed citizens, have been sensitised to some of the issues raised in the public domain. Teachers in both the USA and Scotland were interviewed to ascertain the extent to which they had begun to make connections between what they have heard and read informally about sustainable development and their responsibilities as teachers. The objective of this research was to determine the impact of this informal ‘environmental’ education on teaching practice. 相似文献
