Restricted Opportunities, Personal Choices, Ineffective Policies: What Explains Food Insecurity in Oregon?

This study examines the extent to which household demographics, local economic and social conditions, and federal food security programs explain the likelihood of household food insecurity in Oregon. Between 1999 and 2001, Oregon had the highest average rate of hunger in the nation and ranked in the top five states with respect to food insecurity. Statistical analyses using a multivariate logit model reveal that food insecurity is influenced by much more than demographics and individual choices. County-level factors such as residential location (urban versus rural) and housing costs significantly affect the likelihood that families will be food insecure.food insecurity, food stamps, hunger, rural residence, Food Security and Poverty,

All Tied Up: The Effect of Wearing a Necktie on Acoustic and Perceptual Measures of Male Choral and Solo Singing

The purpose of this study was to assess acoustically (long-term average spectra and multi-dimensional voice profile) and perceptually (participant perceived phonatory ease and expert listening panel) the effect of wearing a necktie on male singing in choral (Experiment 1) and solo (Experiment 2) settings. No study to date has assessed the potential effects of wearing neckties in both choral and solo vocal settings. Among primary results: (a) statistically significant differences in spectral energy between performances with and without a necktie in both the choral (2-4 kHz) and solo (0-10 kHz) settings, (b) increases in mean jitter and shimmer percentage measurements of solo singers with necktie, (c) significant reduction in perceived phonatory ease when singing while wearing a necktie in choral and solo settings, and (d) listener preferences for singing without a necktie in solo and homophonic choral settings. Results were discussed in terms of limitations of the study, suggestions for future research, and implications for voice pedagogy.

Heroic Helping: The Effects of Priming Superhero Images on Prosociality

Two experiments examined how exposure to superhero images influences both prosociality and meaning in life. In Experiment 1 (N = 246) exposed individuals to scenes with superhero images or neutral images. Individuals primed with superhero images reported greater helping intentions relative to the control group, which, in turn, were associated with increased meaning in life (indirect effect only; no direct effect). In Experiment 2 (N = 123), individuals exposed to a superhero poster helped an experimenter in a tedious task more than those exposed to a bicycle poster, though no differences were found for meaning in life. These results suggest that subtle activation of superhero stimuli increases prosocial intentions and behavior

Continuous-Wave Cavity Ring-Down for High-Sensitivity Polarimetry and Magnetometry Measurements

We report the development of a novel variant of cavity ring-down polarimetry using a continuous-wave laser operating at 532 nm for highly precise chiroptical activity and magnetometry measurements. The key methodology of the apparatus relies upon the external modulation of the laser frequency at the frequency splitting between non-degenerate left- and right-circularly polarised cavity modes. The method is demonstrated by evaluation of the Verdet constants of crystalline CeF3 and fused silica, in addition to the observation of gas- and solution-phase optical rotations of selected chiral molecules. Specifically, optical rotations of (i) vapours of alpha-pinene and R-(+)-limonene, (ii) mutarotating D-glucose in water, and (iii) acidified L-histidine solutions, are determined. The detection sensitivities for the gas- and solution phase chiral activity measurements are ~30 microdeg and ~120 microdeg over a 30 s detection period per cavity roundtrip pass, respectively. Furthermore, the measured optical rotations for R-(+)-limonene are compared with computations performed using the Turbomole quantum chemistry package. The experimentally observed optically rotatory dispersion of this cyclic monoterpene was thus rationalised via consideration of its room temperature conformer distribution as determined by the aforementioned single-point energy calculations.Comment: 12 pages, 8 figure

Demographic Determinants of Perceived Barriers to Community Involvement: Examining Rural/Urban Differences

Communities all rely to some degree upon residents to serve in and lead the local organizations that make those communities vital. Recognizing barriers experienced by specific groups helps community leaders identify why various groups do not participate. Using data from the 2000 Social Capital Benchmark Survey, this analysis examines perceived barriers to community involvement among individuals in rural and urban areas. Findings are generally consistent with earlier research into volunteer behavior, but, among several unexpected findings, we note that parents and employed people are more likely to lack the information they think they need, and minority group members, net of other characteristics, feel unwelcomed and ineffective. Patterns sometimes differ for rural and urban places, particularly when comparing men and women. The results highlight barriers that community leaders can seek to reduce and suggest areas where further place-based research could be beneficial.This is an author's peer-reviewed final manuscript, as accepted by the publisher.

Conservation genetics of cyprinid fishes in the upper Nueces River basin in central Texas

Sequences of the mitochondrial (mt) NADH dehydrogenase subunit 5 gene (ND5) were acquired to assess genetic diversity and female effective population size (Nef) of two forms of Cyprinella (C. lepida and C. sp. cf lepida) and two species of Dionda (D. serena and D. texensis) in headwaters of three rivers in the upper Nueces River basin in central Texas. As documented in prior studies, two divergent clades of haplotypes of mtDNA were found in both genera: one in the Frio and Sabinal rivers, representing C. lepida and D. serena; one in the Nueces River, representing C. sp. cf lepida and D. texensis. Levels of variation in mtDNA from C. lepida in the Sabinal River and D. serena in the Frio and Sabinal rivers were comparable to or considerably lower than values documented for populations of several threatened or endangered cyprinids. Estimates of Nef for C. lepida in the Frio River and C. sp. cf lepida in the Nueces River were low, suggesting that adaptive genetic variation through time may be compromised. Of all populations sampled, only D. texensis in the Nueces River appears at present to be genetically stable demographically. An unexpected finding was two individuals resembling C. lepida in the Frio River with a haplotype referable to C. sp. cf lepida; the origin of these individuals is unknown. Two other individuals resembling C. lepida but with haplotypes of mtDNA referable to C. venusta were found in the Frio River and presumably represent relatively recent hybrids. Results of our study indicate that C. lepida, C. sp. cf lepida, and D. serena in the upper Nueces River basin, especially in the Sabinal River drainage, are at appreciable genetic risk
