Understanding Hope: A Review of Measurement and Construct Validity Research

Hope has been discussed by philosophers, theologians, educators, and scientists, to name but a few groups of people, over the preceding two millennia. During the last 15 years, C. R. Snyder and his colleagues at the University of Kansas have developed a theory and associated measures of the hope construct that have received extensive, detailed attention both within and outside the field of psychology. In this chapter, we describe Snyder\u27s hope model and some of the research findings that have supported the validity of this construct. Beginning with a conceptual definition of hope, we move to relevant findings about the usefulness of hope in the lives of individuals in various life arenas. We describe measures developed for assessing hope in children and adults, as well as current issues associated with the validity of hope measurement. Finally, we discuss future directions for further investigation of hope

Shock tube measurements of growth constants in the branched-chain ethane-carbon monoxide-oxygen system

Exponential free radical growth constants have been measured for ethane carbon monoxide oxygen mixtures by monitoring the growth of oxygen atom concentration as manifested by CO flame band emission. Data were obtained over the temperature range of 1200 to 1700 K. The data were analyzed using an ethane oxidation mechanism involving seven elementary reaction steps. Calculated growth constants were close to experimental values at lower temperatures, up to about 1400 K, but at higher temperatures computed growth constants were considerably smaller than experiment. In attempts to explain these results additional branching reactions were added to the mechanism. However, these additional reactions did not appreciably change calculated growth constants

Handbook of Social and Clinical Psychology: The Health Perspective

From 1988 to 1991 Donelson R. Forsyth worked with C.R. Snyder and many other experts in the field of social and clinical psychology, editing a handbook that--at that time--summarized ongoing efforts in what was known as the social-clinical interface. This interface recognized the growing interdependency of these two fields. Up to that time social psychologists were mostly preoccupied with the study of the interpersonal determinants of thought, feeling, and action. Their work was primarily theoretically driven, the behaviors they sought to explain were the sort that occurred in everyday settings, and they preferred to test their hypotheses through laboratory experimentation. Clinical psychologists, in contrast, sought to understand the causes of and cures for dysfunctional behavior. They were concerned with developing effective treatments and diagnostic techniques, the behaviors they puzzled over were abnormal ones, and they preferred to test their hypotheses in field settings. The Handbook that C.R. Snyder and Donelson R. Forsyth developed, however, explored the boundary line separating social and clinical psychology. It included chapters by social psychologists who, recognizing the potential applicability of their theories to clinical practice, had began exploring sources of dysfunction and suggesting socially based treatment strategies. It also included chapters by clinical psychologists not only recognized the role of interpersonal dynamics in adjustment and therapy, but who had begun to integrate social psychological principles and clinical practice. The Handbook of Social and Clinical Psychology (HSCP) served as a comprehensive resource book for theorists, researchers, and scholars working at the interface of social and clinical psychology.https://scholarship.richmond.edu/bookshelf/1167/thumbnail.jp

Orbital-free Bond Breaking via Machine Learning

Machine learning is used to approximate the kinetic energy of one dimensional diatomics as a functional of the electron density. The functional can accurately dissociate a diatomic, and can be systematically improved with training. Highly accurate self-consistent densities and molecular forces are found, indicating the possibility for ab-initio molecular dynamics simulations

Remodelling of the natural product fumagillol employing a reaction discovery approach

In the search for new biologically active molecules, diversity-oriented synthetic strategies break through the limitation of traditional library synthesis by sampling new chemical space. Many natural products can be regarded as intriguing starting points for diversity-oriented synthesis, wherein stereochemically rich core structures may be reorganized into chemotypes that are distinctly different from the parent structure. Ideally, to be suited to library applications, such transformations should be general and involve few steps. With this objective in mind, the highly oxygenated natural product fumagillol has been successfully remodelled in several ways using a reaction-discovery-based approach. In reactions with amines, excellent regiocontrol in a bis-epoxide opening/cyclization sequence can be obtained by size-dependent interaction of an appropriate catalyst with the parent molecule, forming either perhydroisoindole or perhydroisoquinoline products. Perhydroisoindoles can be further remodelled by cascade processes to afford either morpholinone or bridged 4,1-benzoxazepine-containing structures.P50 GM067041 - NIGMS NIH HHS; P50 GM067041-07 - NIGMS NIH HHS; P50 GM067041-08 - NIGMS NIH HHS; P50 GM067041-09 - NIGMS NIH HH
