Universal Screening as the Great Equalizer: Eliminating Disproportionality in Special Education Referrals

The overrepresentation of minority students identified for special education services continues to plague schools and serves as a challenge for researchers and practitioners (Ferri&Conner,2005). Teacher nomination, office discipline referrals (ODR), and functional behavior assessments (FBA) continue to guide referral processes (Bradshaw, Mitchell, O’Brennen, & Leaf, 2010; Eklund, et al., 2009; Mustian, 2010). These methods have been found to be riddled with inconsistencies. Practices used to identify students for behavioral and emotional interventions over-identify students from culturally and linguistically diverse backgrounds. The use of a behavioral and emotional screener to make data-based decisions regarding placement and services could provide an objective assessment of student risk. The first chapter of this dissertation reviews methods used in the identification of students for behavioral and emotional support services. Additionally, the use of universal screening in conjunction with student self-report are proposed as tools for alleviating the overrepresentation of minority students in special education programs for behavioral and emotional disorders. The second chapter of this dissertation explores the measurement equivalence of Behavior Assessment System for Children, Second Edition (BASC-2) Behavioral and Emotional Screening System Student form (BESS Student) across the Black, Hispanic, and White participants in the norming sample. The BESS Student as a universal screening tool is poised to alleviate the disproportionate number of children of color identified by schools as having behavior and emotional disorders. This instrument also provides an avenue to identify students with internalizing disorders who are often overlooked in present referral practices (Bradshaw, Buckley, & Ialongo, 2008; Kataoka, Zhang, & Wells, 2002). The findings of the measurement equivalence study suggests that the BESS Student is, as designed, identifying behavioral and emotional risk across each of the three groups explored. These findings support the use of a universal screening measure as the first step in a multi-step identification and intervention process. Following up with additional assessment to evaluate the specific areas of risk warranting intervention is pivotal to providing appropriate support services and promoting the behavioral and emotional health of students. Implications for research and practice are discussed

Optimizing ground beef lean sources to maximize display color life

It is widely accepted that meat color is the most important influencer of consumers’ meat purchasing decisions. Understanding how ground cow meat discolors is, and will continue to be, very important as a large influx of cull dairy cows in the U.S. meat supply is predicted. Optimal management and more timely marketing of cows should result in increased revenue for the beef industry. However, many valuable by-products from cows have been labeled as specified risk materials accompanied by a lost value. Thus, there is an unprecedented need to add value to cow meat. Research characterizing cow muscles and how to optimally use them for ground beef production could increase the value of cull cows and result in improved management and use of meat from cull cows. Our objectives were to evaluate the display color life of ground beef from different muscle combinations that vary in pre-established color stability values and determine if using beef or dairy cow meat affects color dynamics and stability of ground beef

Sexual Orientation, Sexual Arousal, and Finger Length Ratios in Women

In general, women show physiological sexual arousal to both sexes. However, compared with heterosexual women, homosexual women are more aroused to their preferred sex, a pattern typically found in men. We hypothesized that homosexual women’s male-typical arousal is due to their sex-atypical masculinization during prenatal development. We measured the sexual responses of 199 women (including 67 homosexual women) via their genital arousal and pupil dilation to female and male sexual stimuli. Our main marker of masculinization was the ratio of the index to ring finger, which we expected to be lower (a masculine pattern) in homosexual women due to increased levels of prenatal androgens. We further measured observer- and self-ratings of psychological masculinity–femininity as possible proxies of prenatal androgenization. Homosexual women responded more strongly to female stimuli than male stimuli and therefore had more male-typical sexual responses than heterosexual women. However, they did not have more male-typical digit ratios, even though this difference became stronger if analyses were restricted to white participants. Still, variation in women's digit ratios did not account for the link between their sexual orientation and their male-typical sexual responses. Furthermore, homosexual women reported and displayed more masculinity than heterosexual women, but their masculinity was not associated with their male-typical sexual arousal. Thus, women’s sexual and behavioral traits, and potential anatomical traits, are possibly masculinized at different stages of gestation

Antisense Suppression of the Small Chloroplast Protein CP12 in Tobacco Alters Carbon Partitioning and Severely Restricts Growth

Abstract The thioredoxin-regulated chloroplast protein CP12 forms a multienzyme complex with the Calvin-Benson cycle enzymes phosphoribulokinase (PRK) and glyceraldehyde-3-phosphate dehydrogenase (GAPDH). PRK and GAPDH are inactivated when present in this complex, a process shown in vitro to be dependent upon oxidized CP12. The importance of CP12 in vivo in higher plants, however, has not been investigated. Here, antisense suppression of CP12 in tobacco (Nicotiana tabacum) was observed to impact on NAD-induced PRK and GAPDH complex formation but had little effect on enzyme activity. Additionally, only minor changes in photosynthetic carbon fixation were observed. Despite this, antisense plants displayed changes in growth rates and morphology, including dwarfism and reduced apical dominance. The hypothesis that CP12 is essential to separate oxidative pentose phosphate pathway activity from Calvin-Benson cycle activity, as proposed in cyanobacteria, was tested. No evidence was found to support this role in tobacco. Evidence was seen, however, for a restriction to malate valve capacity, with decreases in NADP-malate dehydrogenase activity (but not protein levels) and pyridine nucleotide content. Antisense repression of CP12 also led to significant changes in carbon partitioning, with increased carbon allocation to the cell wall and the organic acids malate and fumarate and decreased allocation to starch and soluble carbohydrates. Severe decreases were also seen in 2-oxoglutarate content, a key indicator of cellular carbon sufficiency. The data presented here indicate that in tobacco, CP12 has a role in redox-mediated regulation of carbon partitioning from the chloroplast and provides strong in vivo evidence that CP12 is required for normal growth and development in plants.</jats:p
