Not-For-Profit Organizations And For-Profit Businesses: Perceptions And Reality

Not-for-profit organizations represent an important portion of the gross domestic product of the United States; yet there are many misconceptions in the business world regarding not-for-profits.  This paper analyzes two surveys -- one of business persons and the other of seniors in an undergraduate business program – to determine the extent of the suspected misconceptions. Then the paper presents factual support to correct typical misconceptions regarding how not-for-profit organizations operate.&nbsp

Vibrational analyses of 2,4-dichloropentane and 2,4,6-trichloroheptane

This study of the vibrational spectra of 2,4-dichloropentane and 2,4,6-trichloroheptane uses normal coordinate calculations as a probe for the presence of different molecular conformers. The calculations use a complete valence force field for secondary chlorides which was developed by fitting the observed vibrational frequencies of model compounds. Observed and calculated frequencies agree well. The results of these calculations on dl and meso 2,4-dichloropentane and on isotactic 2,4,6-trichloroheptane indicate the presence of conformers other than those which are accepted as sterically preferred.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/22431/1/0000881.pd

A complete general valence force field for secondary chlorides

A general valence force field for secondary chlorides has been refined which includes torsional force constants based on assignments of low frequency modes in model compounds. This force field also incorporates force constants related to observed intermolecular interactions. The good agreement between observed and calculated frequencies indicates that this force field will be useful in studying the conformation of secondary chlorides.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/33779/1/0000032.pd

Champ or chump? Challenge and threat states during pressurized competition

Copyright © 2013 Human Kinetics, IncThe present research examined the immediate impact of challenge and threat states on golf performance in both real competition and a laboratory-based task. In Study 1, 199 experienced golfers reported their evaluations of competition demands and personal coping resources before a golf competition. Evaluating the competition as a challenge (i.e., sufficient resources to cope with demands) was associated with superior performance. In Study 2, 60 experienced golfers randomly received challenge or threat manipulation instructions and then performed a competitive golf-putting task. Challenge and threat states were successfully manipulated and the challenge group outperformed the threat group. Furthermore, the challenge group reported less anxiety, more facilitative interpretations of anxiety, less conscious processing, and displayed longer quiet eye durations. However, these variables failed to mediate the group-performance relationship. These studies demonstrate the importance of considering preperformance psychophysiological states when examining the influence of competitive pressure on motor performance

Assignment of torsion and low frequency bending vibrations of secondary chlorides

Far infrared and Raman spectra of 2-chloropropane, 2-chlorobutane and dl- and meso-2,4-dichloropentane have been analyzed in order to assign the torsional force constants in the valence force field for secondary chlorides. Band assignments have been based on experimental data as well as preliminary normal vibration calculations. With incorporation of torsional force constants, and a global refinement of the force field, the observed low frequency bands of the above molecules, as well as those of 3-chloropentane, are very well accounted for.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/33808/1/0000064.pd

Spatially modelling the association between access to recreational facilities and exercise: the ‘Multi-ethnic study of atherosclerosis’

Numerous studies have investigated the relationship between the built environment and physical activity. However these studies assume that these relationships are invariant over space. In this study, we introduce a novel method to analyze the association between access to recreational facilities and exercise allowing for spatial heterogeneity. In addition, this association is studied before and after controlling for crime, a variable that could explain spatial heterogeneity of associations. We use data from the Chicago site of the Multi-Ethnic Study of Atherosclerosis of 781 adults aged 46 years and over. A spatially varying coefficient Tobit regression model is implemented in the Bayesian setting to allow for the association of interest to vary over space. The relationship is shown to vary over Chicago, being positive in the south but negative or null in the north. Controlling for crime weakens the association in the south with little change observed in northern Chicago. The results of this study indicate that spatial heterogeneity in associations of environmental factors with health may vary over space and deserve further exploration

Persistent elastic behavior above a megathrust rupture patch: Nias island, West Sumatra

We quantify fore-arc deformation using fossil reefs to test the assumption commonly made in seismic cycle models that anelastic deformation of the fore arc is negligible. Elevated coral microatolls, paleoreef flats, and chenier plains show that the Sumatran outer arc island of Nias has experienced a complex pattern of relatively slow long-term uplift and subsidence during the Holocene epoch. This same island rose up to 2.9 m during the Mw 8.7 Sunda megathrust rupture in 2005. The mismatch between the 2005 and Holocene uplift patterns, along with the overall low rates of Holocene deformation, reflects the dominance of elastic strain accumulation and release along this section of the Sunda outer arc high and the relatively subordinate role of upper plate deformation in accommodating long-term plate convergence. The fraction of 2005 uplift that will be retained permanently is generally <4% for sites that experienced more than 0.25 m of coseismic uplift. Average uplift rates since the mid-Holocene range from 1.5 to −0.2 mm/a and are highest on the eastern coast of Nias, where coseismic uplift was nearly zero in 2005. The pattern of long-term uplift and subsidence is consistent with slow deformation of Nias along closely spaced folds in the north and trenchward dipping back thrusts in the southeast. Low Holocene tectonic uplift rates provide for excellent geomorphic and stratigraphic preservation of the mid-Holocene relative sea level high, which was under way by ∼7.3 ka and persisted until ∼2 ka
