Introducing Immersion Techniques to Shift Augmentative and Alternative Communication Uses: A Brief Report
Get PDFCaregivers and interventionists all need the same information about how to support language development when language is being developed through augmentative communication systems. Through learning about the importance of immersion practices, caregivers and interventionalists were empowered to support and advocate for various types of verbal expressions and speech that occurred through speech generating devices
The Efficacy of an In-Vivo Chaining Procedure Compared to POV-VM Chaining Procedure to Teach a Task to Children with Autism
Get PDFAutism Spectrum Disorder (ASD) is a neurodevelopmental disorder which includes symptoms such as repetitive or restricted patterns of behavior, and deficits in social communication (American Psychiatric Association, 2013) and affects approximately 1 in 36 children aged 8 and older (Centers for Disease Control and Prevention, 2020). Children with this disorder face unique challenges when it come to learning academic and social skills (Gardner & Wolfe, 2013). Chaining is an effective intervention for teaching individuals with disabilities a variety of skills (Cuvo et al., 1978; Horner & Keilitz, 1975; Shrestha et al., 2013; Tarbox, et al., 2009). Video modeling, where a subject performs a behavior they have previously seen modeled on a videotape (Nikopoulos & Keenan, 2004 and more recently point-of-view video modeling (POV-VM) which provides the instruction from the subject\u27s vantage point may also be effective for teaching children with autism and other disabilities needed skills (Shukla-Mehta et al., 2010). There is some empirical evidence that chaining used in conjunction with POV-VM may provide effective intervention (Jewett, et al., 2012; Moore, et al., 2013; Shrestha, et al., 2013) yet no studies have directly compared a chaining procedure taught by traditional methods to a chaining procedure which is exclusively taught through the use of POV-VM
Organizational Readiness as a Predictor of Successful Trauma-Informed Change within Child Welfare Agencies
Get PDFThe literature is replete with calls to reform the child welfare system (Dettlaff et al., 2020; Lindell et al., 2020; McTavish et al., 2018). Five child welfare organizations in one northeastern state in the U.S. participated in a pilot program to implement trauma-informed organizational change (TOC). This study explored the extent to which child welfare agencies demonstrated readiness to adopt change. The researcher used a directed content analysis approach to analyze previously collected staff meeting minutes, consultant notes, and other TOC-related documents collected during implementation. Findings support Armenakis et al.\u27s (2000) organizational readiness for change theory, which suggests that increased readiness for organizational change leads to increased implementation success
Speech and Language Assessment Practices for Bilingual Children in the School Setting: Where do we go from here?
Get PDFAbstract
The field of speech-language pathology has demonstrated growth in bilingual assessment and evaluations. However, many questions remain regarding formal and informal assessment practices, intervention recommendations, and cultural competency or responsiveness. Sixty-one SLPs in Virginia completed a survey on demographics, bilingual assessment practices, cultural competence, and language development of ELL students. Seven SLPs who work with bilingual and/or ELL students were also interviewed to ascertain bilingual assessment practices, cultural competence, and language development knowledge. Areas of concern included assessment of bilingual students, lack of developmental norms and standardized assessment tools in languages other than English, and lack of knowledge of the nature of second language acquisition, and difficulty distinguishing a language difference from a language disorder. Assessment practices with interpreters in person post pandemic, defining roles and responsibilities of interpreters prior to the assessment and limited collaboration or use of the briefing, interaction, and debriefing (BID) were discussed. Additionally, three themes regarding the assessment practices emerged related to language difference versus disorder and changes to assessment in relation to the COVID pandemic. Informal assessment procedures measures were commonly reported as evaluations utilized for students who are bilingual and ELL along with teacher/parent input, interpreters, parent liaisons, and bilingual SLPs. Strengths and areas of improvement in cultural competency are discussed.

Simultaneous Quantification of Carbaryl, Chlorpyrifos, and Paraquat in a Municipal Wastewater Treatment Plant by SPE-RP-HPLC-PDA-FD Method
No full textThree commonly used pesticides; carbaryl, chlorpyrifos, and paraquat were quantified by using solid-phase extraction (SPE) technique and high-performance liquid chromatography with photodiode-array and fluorescence detectors (HPLC-PDA-FD) in wastewater treatment plant. After solid-phase extraction, separation and quantification were done using a C18 analytical column, an isocratic mobile phase consisting of acetonitrile/water (70%:30% v/v) at a flow rate of 1 mL/min, and column oven maintained at 35 °C. Analyte concentrations were detected simultaneously at 230 nm, 254 nm, and 270 nm. PDA detection at 230 nm gave LOD and LOQ values of 0.65 mg/L and 1.98 mg/L, 0.39 mg/L and 1.17 mg/L, for carbaryl and chlorpyrifos, respectively. Fluorescence emission peaks, λexc (270 nm) and λem (320 nm) were chosen for detection. FD gave LOD and LOQ values of 0.98 mg/L and 2.96 mg/L, 1.57 mg/L and 4.76 mg/L, for carbaryl and chlorpyrifos, respectively. Calibration curves based on integrated peak area counts gave satisfactory linearity (R2 ≥ 0.9995). Although exhibiting low detector sensitivity for paraquat at 230 nm, this method is deemed best suited for routine analysis in Wastewater Treatment Plants (WWTPs). The developed and validated method using lower-cost dual detectors, PDA-FD, as a substitute for the higher-cost mass spectrometry is suitable for routine quantitative and qualitative analysis of carbaryl, paraquat, and chlorpyrifos in wastewater and environmental samples
Older Adults’ Health, Ethnicity, and Daily Life
Get PDFAbstract
This study examines the relationship between ethnicity and daily functional disabilities among older adults, focusing on Activities of Daily Living (ADLs) and Instrumental Activities of Daily Living (IADLs). The analysis uses data from the 2020 National Social Life, Health, and Aging Project (NSHAP) survey, which included a sample of individuals aged 57-85 (n=3,005). Respondents provided information on their demographic background (e.g., income, gender, race, age, health, retirement, and marital status) and socioeconomic characteristics through telephone interviews.
The study hypothesized that ethnic differences would be evident in perceived difficulties with ADLs and IADLs in later life. To assess these relationships, both MANOVA and regression analyses were conducted. The results showed that African American and Hispanic older adults reported greater difficulty with ADLs and IADLs compared to their Anglo counterparts, highlighting significant ethnic disparities in daily functional challenges. These findings are consistent with the convoy model, suggesting that ethnicity significantly influences health outcomes and functional abilities in later life. Future research should include a broader range of variables to deepen our understanding of the complex interplay between demographic factors and health outcomes, including daily functional disabilities, among older adults.

Depositional Facies and Petrophysical Characterization of the Leonardian Carbonate (Lower Clear Fork), Tex-Mex, S.E. Field, Central Basin Platform, West Texas
Get PDFThe Lower Clear Fork from Tex-Mex, S.E. Field on the Central Basin Platform is a typical complex reservoir that displays high heterogeneity in lithological and petrophysical properties. The unit represents a producing reservoir succession of Leonardian platform carbonates deposited in shallow marine water during the Early Permian. The sediment of the Lower Clear Fork is composed of a mixed succession of dolomite interbedded with anhydrite, minor clay minerals, and siliciclastics. The high heterolithic nature of the reservoir makes efficient recovery of hydrocarbons difficult. This situation requires an understanding of the variability in depositional facies in terms of mineralogy, depositional textures and structures, and an assessment of its petrophysical properties. As of December 2023, cumulative production of hydrocarbon from the Tex-Mex, S.E. Field reached about 88,308 barrels of oil equivalent.
The study at Tex-Mex, S.E. Field utilized 338.9 ft (103.3 m) of Lower Clear Fork cored sample, core data, and wireline data from a key well. Key data utilized included core descriptions, wireline logs, routine core analysis data, petrographic thin sections, and whole rock mineralogical data from X-ray Diffraction. These data helped to (1) determine the paleoenvironments under which the Lower Clear Fork sediments were deposited, (2) build a core-calibrated petrophysical mineral model of the Lower Clear Fork from wireline logs and XRD mineralogy, and (3) assess the petrophysical properties of the Lower Clear Fork reservoir.
The integration of core/log analysis, XRD data, routine core data, and petrographic observations revealed seven (7) facies regrouped into four (4) major facies associations each representing the mineralogy, sedimentary textures, pore characteristics, and paleodepositional environment. The Lower Clear Fork, a second-order Leonardian sequence represents facies transitioning from dolomitized inner to ramp crest facies (skeletal/peloidal wackestone to grain-dominated packstone) in the lower part, to dolomitized restricted lagoon and tidal flats/sabkha facies (dolomudstone/anhydrite) in the upper part. The petrophysical characteristics of the Lower Clear Fork reservoir were dominantly controlled by post-depositional processes that altered the primary carbonate mineralogy and pore development. The principal diagenetic processes included reflux dolomitization, gypsum precipitation (later transformed into anhydrite), and dissolution of anhydrite and dolomite cement.
Mineralogical results revealed the dominance of dolomite, anhydrite with minor amounts of clay, and siliciclastics. Calibrated porosity values within the interval vary from 0.5% to 10%, while Klinkenberg permeability was in the range of 10-4 mD to 17.6 mD. The Lower Clear Fork facies showed dominance of high water saturation values, reaching up to 95.4%, and comparatively low oil saturation levels, peaking at a value of 14.4% in the dolopackstone facies. Overall, the Lower Clear Fork reservoir is of low quality, however, the grain-rich dolopackstone facies offered the most favorable reservoir properties when compared with other facies in the interval
21st Century Community Learning Centers: Program Evaluation Evidence from Texas
Get PDFTexas afterschool programs strive to enhance academic performance and meet students\u27 needs, yet gaps in program quality persist. This study evaluated 21st Century Community Learning Centers’ performance in reading, math, GPA, attendance, in-school suspension, and engagement, both within these categories and against program goals and demographics. Theoretical frameworks used in this study include the logic model, social justice theory, and cultural relevance theory. This quantitative study utilized a nonexperimental and secondary data research design which utilized five statistical tests: the Pearson Product-Moment Correlation, One-Way repeated ANOVA, Spearman Correlation, the Independent Samples t-Test, and the Mann-Whitney U Test. Results showed that students who attended afterschool programs most of the school year had better overall attendance and improved math performance. Black students, male students, and SPED students had lower performance improvement than other demographics, which suggests issues with program quality related to demographics. Implications indicate that programs should promote year-round participation, innovative class offerings, community involvement, and culturally inclusive programming guided by a logic model to drive continuous improvement
Closet Space
Get PDFCloset Space is an exhibition investigating what makes a home. Through the creation of six drawings and seven prints, I investigate the relationship between isolation and companionship. This body of work explores the concept that a home is not simply a physical structure made up of walls and doors. Instead, it is about the emotional connections we create with places and people. Through fragmented memories, imagined environments, and a desire to connect with others, I address that the true meaning of home lies in our emotional attachments to inhabited spaces and the people we share them with. Being queer in the South heavily relies on the ability to perform. Balancing familial and societal expectations while staying true to myself was difficult. I use exaggerated perspectives and limited color palettes to examine my association with domestic interior settings, my sense of self, and my connections with others
