Social Networks and Homelessness Among Women Heads of Household

To examine possible bidirectional relationships between homelessness and deficient social networks, we compared the networks of 251 mothers before, and approximately 5 years after, their families entered shelters with networks of 291 consistently housed poor mothers. At Time 1, more women on the verge of homelessness than housed women reported that they had mothers, grandmothers, friends, and relatives but fewer believed these network members were housing resources. At Time 2, after homeless women were rehoused, these network differences between consistently housed and formerly homeless women had largely disappeared. Contrary to prior research findings, formerly homeless mothers did not report smaller networks, more children or fewer partners. However, formerly homeless women did report fewer positive functions. Because of city policies, homeless mothers were frequently rehoused far from network members.     

Contextual Factors Affecting the Organizational Commitment of Diverse Police Officers: A Levels of Analysis Perspective

This study examined the relationship of contextual factors to organizational commitment among 372 police officers in 13 police commands in New York City's public housing projects. Setting-level variables were formed by aggregating officers' perceptions of management support and fairness and management sensitivity to diversity within commands and within three subgroups formed by gender and ethnicity. Individual-level measures were deviations from these subgroup means within commands as well as perceptions of support from family and social support and negative interactions within commands. Overall, path analyses, confirmed by hierarchical linear modeling, showed direct setting-level effects for management support and fairness, but not for sensitivity to diversity, on organizational commitment. Both women and minority men experienced more negative social interactions than white men; support from management, co-workers, and family were important predictors of commitment. Family support was particularly important for women.     

Curriculum-based measurement: Conceptual underpinnings and integration into problem-solving assessment

This article presents a case study exemplifying the use of curriculum-based measurement (CBM) in educational decision making. CBM is portrayed as more than just a set of brief fluency tests with strong conceptual ties to three related assessment models, viz., behavioral, ecological, and problem-solving assessment. The key elements of each of these models are delineated. A case study is presented to show how CBM is integrated into problem-solving educational assessment and decision-making practices.     

Phonetic disintegration in aphasia: Acoustic analysis of spectral characteristics for place of articulation

In this study, we attempted to determine whether phonetic disintegration of speech in Broca's aphasia affects the spectral characteristics of speech sounds as has been shown for the temporal characteristics of speech. To this end, we investigated the production of place of articulation in Broca's aphasics. Acoustic analysis of the spectral characteristics for stop consonants were conducted. Results indicated that the static aspects of speech production were preserved, as Broca's aphasics seemed to be able to reach the articulatory configuration for the appropriate place of articulation. However, the dynamic aspects of speech production seemed to be impaired, as their productions reflected problems with the source characteristics of speech sounds and with the integration of articulatory movements in the vocal tract. Listener perceptions of the aphasics' productions were compared with acoustic analyses for these same productions. The two measures were related; that is, the spectral characteristics of the utterances provided salient cues for place of articulation perception. An analysis of the occurrences of errors along the dimensions of voicing and place showed that aphasics rarely produce utterances containing both voice and place substitutions.     

Phonological priming reflects lexical competition

A phonological relationship between a prime and a target produces facilitation when one or two initial phonemes are shared (low-similarity facilitation) but produces interference when more phonemes are shared (high-similarity interference; Slowiaczek & Hamburger, 1992). Although low-similarity facilitation appears to be a strategic effect (Goldinger, Luce, Pisoni, & Marcario, 1992), this result cannot generalize to high-similarity interference because the two effects are dissociated (Slowiaczek & Hamburger, 1992). In the present study, strategic processing in high-similarity interference was investigated. The phonological relatedness proportion (PRP) and the prime-target interstimulus interval (ISI) were varied in a shadowing experiment. Low-similarity facilitation was found only with a high PRP and long ISI, but high-similarity interference was found regardless of PRP and ISI. These results suggest that strategies influence low-similarity facilitation, but high-similarity interference reflects automatic processing.     

Homelessness, Mental Illness, and Criminal Activity: Examining Patterns Over Time

This study examined whether street homelessness, sheltered homelessness, and the severity of psychological symptoms predicted non-violent and violent crime among 207 mentally ill participants who were homeless at baseline. Participants were interviewed at 9 time points over 4 years. Hierarchical linear modeling (HLM) was used to examine whether changes in homelessness status and symptom severity predicted changes in criminal activity over time. Results indicated that homelessness both on the streets and in shelters and psychological symptom severity predicted increases in non-violent crime. Sheltered homelessness and symptom severity predicted increases in violent crime, although street homelessness did not. A separate mediational analysis with 181 participants showed that the relationship between diagnosis of a psychotic disorder and both non-violent and violent criminal activity was partially mediated through the severity of psychotic symptoms. Implications for research and intervention are discussed.
