Multiculturalism to Diversity: Implications from an SLP’s Journey

The current essay will review significant events in the history of the multicultural movement in the United States over the past 37 years. It is intended to encourage young scholars to study this movement, both the strengths and weaknesses of it, and examine their perceptions of current circumstances and proposed solutions for the discipline of speech-language pathology

Positive Messages And Traditional Therapy For Three Children With Persistent Stuttering

As children age, they are less likely to experience spontaneous recovery from stuttering and are likely to develop negative attitudes about talking, necessitating counselling to address these feelings. The current exploratory case study examines children’s response to traditional speech therapy to address fluency combined with a programmed message to modify negative attitudes about talking. A standard narration, saved to a compact disk (CD), was used as a counselling experience for children, ages 6, 7, and 10;11 years, recruited from a university clinic predominantly serving African American children. A one-tailed Mann-Whitney U-test was performed to examine differences in stuttering across three pretreatment sessions to treatment results from two experimental sessions. The analysis indicated that participants who completed the two treatment sessions stuttered significantly less during the sessions that included the CD, with a moderate clinical effect size as indicated by r, (Mdn = 9), U = 12, p ≤ .05, r = .53. For 2 of 3 participants who completed post-testing with the Stuttering Severity Instrument-3 (SSI-3), testing indicated a reduction in overall scores and stuttering severity (Riley, 1994). There is a need for future studies to examine the content of motivational messages as components of therapy to address stuttering

Molecular gas in extreme star-forming environments: the starbursts Arp220 and NGC6240 as case studies

We report single-dish multi-transition measurements of the 12^CO, HCN, and HCO^+ molecular line emission as well as HNC J=1-0 and HNCO in the two ultraluminous infra-red galaxies Arp220 and NGC6240. Using this new molecular line inventory, in conjunction with existing data in the literature, we compiled the most extensive molecular line data sets to date for such galaxies. The many rotational transitions, with their different excitation requirements, allow the study of the molecular gas over a wide range of different densities and temperatures with significant redundancy, and thus allow good constraints on the properties of the dense gas in these two systems. The mass (~(1-2) x 10^10 Msun) of dense gas (>10^5-6 cm^-3) found accounts for the bulk of their molecular gas mass, and is consistent with most of their IR luminosities powered by intense star bursts while self-regulated by O,B star cluster radiative pressure onto the star-forming dense molecular gas. The highly excited HCN transitions trace a gas phase ~(10-100)x denser than that of the sub-thermally excited HCO^+ lines (for both galaxies). These two phases are consistent with an underlying density-size power law found for Galactic GMCs (but with a steeper exponent), with HCN lines tracing denser and more compact regions than HCO^+. Whether this is true in IR-luminous, star forming galaxies in general remains to be seen, and underlines the need for observations of molecular transitions with high critical densities for a sample of bright (U)LIRGs in the local Universe -- a task for which the HI-FI instrument on board Herschel is ideally suited to do.Comment: 38 pages (preprint ApJ style), 3 figures, accepted for Ap

Speech Delay in Seven Siblings with Unusual Sound Preferences

By the age of 8 years, children who are developing normally show almost adult speech skills. Children with serious phonological disorders, however, may exhibit significant differences in development well beyond the age of 8 years with little or no improvement in speech if therapy is not provided. This is a descriptive study of seven siblings, ranging in age from 6 to 14 years of age who had never attended school or received speech therapy until these ages. All of the children exhibited moderate to severe speech disorder with no evidence of predisposing genetic factors, hearing loss, physical abuse, or prenatal drug exposure. These cases, which would obviously be impossible to duplicate in a controlled study, provide strong support for the efficacy of speech therapy. Children with serious speech delays will not improve appreciably without direct intervention
