Integrated software for analysis and synthesis of voice quality

Voice quality is an important perceptual cue in many disciplines, but knowledge of its nature is limited by a poor understanding of the relevant psychoacoustics. This article (aimed at researchers studying voice, speech, and vocal behavior) describes the UCLA voice synthesizer, software for voice analysis and synthesis designed to test hypotheses about the relationship between acoustic parameters and voice quality perception. The synthesizer provides experimenters with a useful tool for creating and modeling voice signals. In particular, it offers an integrated approach to voice analysis and synthesis and allows easy, precise, spectral-domain manipulations of the harmonic voice source. The synthesizer operates in near real time, using a parsimonious set of acoustic parameters for the voice source and vocal tract that a user can modify to accurately copy the quality of most normal and pathological voices.

Coparenting Profiles in the Context of Mexican‐Origin Teen Pregnancy: Links to Mother–Daughter Relationship Quality and Adjustment

The current study explored the multifaceted nature of the mother–adolescent coparental relationship with data from 167 Mexican‐origin adolescent mothers and their own mothers at 10 months post childbirth. Profiles of mother–adolescent coparenting were created with latent profile analysis using adolescents’ reports of three dimensions of coparenting (communication, involvement, and conflict). Four profiles were identified: (a) Harmonious Coparents (equal involvement, high communication, low conflict); (b) Harmonious‐Adolescent Primary (adolescent is more involved than mother, high communication, low conflict); (c) Conflictual Coparents (equal involvement, high communication, high conflict); and (d) Conflictual‐Adolescent Primary (adolescent is more involved than mother, moderate communication, high conflict). Families characterized by high mother–daughter conflict and psychological control prior to childbirth were more likely to belong in the Conflictual Coparents profile. In addition, adolescents’ and mothers’ depressive symptoms and parenting efficacy after childbirth were linked to profile membership, such that the Harmonious‐Adolescent Primary profile reported the most positive adjustment patterns, whereas profiles with high coparental conflict (i.e., Conflictual Coparenting and Conflictual‐Adolescent Primary profiles) showed the least positive adjustment patterns. Discussion considers the applied implications of identifying precursors to healthy and problematic mother–daughter coparenting for families of adolescent mothers in the early years of parenting.     

The Disproportionality Dilemma: Patterns of Teacher Referrals to School Counselors for Disruptive Behavior

Disproportionality plagues schools nationwide in special education placement, dropout, discipline referral, suspension, and expulsion rates. This study examined predictors of teacher referrals to school counselors for disruptive behavior in a sample of students selected from the Educational Longitudinal Study 2002 (National Center for Education Statistics, n.d.). Findings demonstrated that students’ race predicted English teacher referrals; students’ gender, previous disciplinary infractions, and teachers’ postsecondary expectations for students predicted English and math teacher referrals. Implications for practice, policy, and research are discussed.     

Development of the Multidimensional Acculturative Stress Inventory for adults of Mexican origin

The Multidimensional Acculturative Stress Inventory (MASI), a 36-item stress measure that was developed to assess acculturative stress among persons of Mexican origin living in the United States, was tested on a community sample of 174 adults (117 women, 57 men). Principal-components analyses yielded 4 stable and internally consistent factors: Spanish Competency Pressures (7 items), English Competency Pressures (7 items), Pressure to Acculturate (7 items), and Pressure Against Acculturation (4 items). These 4 factors accounted for 64.4% of the variance and correlated in the expected directions with criterion measures of acculturation and/or psychological adjustment. Further reliability and validity testing of the MASI is discussed as well as the utility of this measure in assessing acculturative stress among adults of Mexican origin.     

Religion and the Recovery of Addicted Women

Personal interviews were conducted with 102 African-American and Anglo-American women in Texas coastal communities to determine the involvement of religious organizations in women's initiation and maintenance of recovery from drug addiction, the extent of women's help-seeking for recovery, and women's spiritual needs. Means, frequencies, chi squares, Pearson's correlations, and one-way ANOVAs were used to describe the data. Religious organizations helped about one-third of the women to begin or stay in recovery, primarily through counseling or ministering to spiritual needs. Only one-fourth of the women had sought help from churches. The predominant spiritual needs were forgiveness, love, and understanding. Implications for research and outreach are given.     

Harmonic structure as a determinant of melodic organization

Musicians and nonmusicians indicated whether a two-note probe following a tonally structured melody occurred in the melody. The critical probes were taken from one of three locations in the melody: the two notes (1) ending the first phrase, (2) straddling the phrase boundary, and (3) beginning the second phrase. As predicted, the probe that straddled the phrase boundary was more difficult to recognize than either of the within-phrase probes. These findings suggest that knowledge of harmonic structure influences perceptual organization of melodies in ways analogous to the influence of clause relations on the perceptual organization of sentences. They also provide evidence that training plays an important role in refining listeners’ sensitivity to harmonic variables.     

The influence of gender labels on the sex typing of imaginary occupations

Social scientists have been concerned not only with gender stratification within the occupational labor force but with young peoples' recognition and aspiration toward same-gender careers. In this paper we investigate how gender labels influence individuals' evaluational sex typing of occupations. Four gender-marked booklets were constructed such that six imaginary occupations within the story were performed by persons labeled as women, men, both men and women, or individuals. College, high-school, and fifth-and third-grade students were asked to evaluate whether a gender-marked occupation was a position for women, men, or both sexes and possible for girls and boys. Students were also asked to indicate which occupations they preferred. Not only were the occupations classified in relation to the gender labels, but occupational gender barriers were perceived. In essence, males were restricted from engaging in female-labeled jobs and females were restricted from engaging in male-labeled jobs. However, career aspirations     

The Multidimensional Model of Broaching Behavior

The multidimensional model of broaching behavior (MMBB) is introduced as a heuristic that addresses multicultural counseling and social justice competence. The MMBB includes humanistic skills that allow counselors to broach clients’ racial, ethnic, and cultural (REC) concerns in an effort to develop strong therapeutic alliances and alleviate distress. This article provides illustrative examples of the 4 MMBB dimensions: intracounseling, intraindividual, intra-REC, and inter-REC. Implications for the counseling profession and practice are described, and directions for future research are presented.
