The role of distinctive features in the dichotic perception of vowels

A dichotic listening experiment was conducted to determine if vowel perception is based on phonetic feature extraction as is consonant perception. Twenty normal right-handed subjects were given dichotic CV syllables contrasting in final vowels. It was found that, unlike consonants, the perception of dichotic vowels was not significantly lateralized, that the dichotic perception of vowels was not significantly enhanced by the number of phonetic features shared, and that the occurrence of double-blend errors was not greater than chance. However, there was strong evidence for the use of phonetic features at the level of response organization. It is suggested that the differences between vowel and consonant perception reflect the differential availability of the underlying acoustic information from auditory store, rather than differences in processing mechanisms.     

Nonchildhood Sexual Abuse in Mexican American and Mexican College Students

This study aimed to assess and compare sexual abuse (SA) rates in female and male Mexican American college students (N = 514) and 2 samples of Mexican college students (N = 161 and N = 227). Participants responded to the Sexual Experiences Survey Victim Form (SES-SFV). SA prevalence and frequency rates were compared between sample groups for 3 categories of SA: nonchildhood SA (SA-NC, experienced since age 14), SA experienced in the previous 12 months (SA-12M), and lifetime self-labeled SA (SA-LL, any experience identified as abuse or rape by participants). Higher rates of self-reported SA were consistently found for Mexican versus U.S. samples. However, SA incidence was also consistently higher in older individuals and females; more recently experienced SA was reported at lower rates and with greater gender congruence than more distal SA; and variation between Mexican samples was roughly equal to variation between Mexican and U.S. samples. Findings show cross-national variation in SA rates.     

Personal Control as a Mediator and Moderator Between Life Strains and Psychological Well-Being in the Unemployed

This study surveyed 214 unemployed adults on well-being, the latent (status, social support, activity, time structure, collective purpose) and manifest benefits (financial strain) of employment, and personal control. We tested whether personal control would predict well-being over and above the effects of the latent and manifest benefits, and tested whether it moderated or mediated the relationship between the latent and manifest benefits and well-being. Personal control explained additional variance over and above the latent and manifest benefits; it moderated the effect of both activity and financial strain on well-being; and it mediated the relationship between financial strain, time structure, collective purpose, status, and well-being. Implications for theory and practice are discussed.     

Exploring Counselor Experiences of Training in Relational Depth: An Interpretative Phenomenological Inquiry

Relational depth is an emergent counseling construct that captures the profound connection felt by client and counselor in moments of therapeutic encounter. We used interpretative phenomenological analysis to understand how 10 doctoral counseling students perceived curricular experiences designed to facilitate their ability to engage in relational depth. We identified the following themes: mutuality, counselor growth, externalized to internalized expectations, authenticity, impact of relational depth educational experiences, and relational depth reflection and articulation.     

Improving Middle School Professional Development by Examining Middle School Teachers' Application of Literacy Strategies and Instructional Design

The goal of this article is to explore the effects of professional development on middle school teachers' understanding and application of literacy strategies supporting and enhancing instruction across the curriculum. This study investigated the extent to which reading and writing strategies, along with sound instructional design, were implemented by middle school teachers in their content areas based on data collected from self-reports (i.e., strategy and design checklists) and authors' classroom observations. Results from the analysis of the data collected suggest that the sampled middle school teachers used a wide variety of instructional strategies and instructional designs throughout their teaching. While certain instructional designs (whole-class discussion) and strategies (note-taking and graphic organizers) were used universally throughout the school, perhaps more important was the fact that others were selected dependent upon the unique content area they taught.     

Efficient spatio-temporal data mining with GenSpace graphs

We describe a method for spatio-temporal data mining based on GenSpace graphs. Using familiar calendar and geographical concepts, such as workdays, weeks, climatic regions, and countries, spatio-temporal data can be aggregated into summaries in many ways. We automatically search for a summary with a distribution that is anomalous, i.e., far from user expectations. We repeatedly ranking possible summaries according to current expectations, and then allow the user to adjust these expectations. We also choose a propagation path in the GenSpace subgraph that reduces the storage and time costs of the mining process.
