In Consideration of Latino Children: a sociocultural perspective of literacy skills development using Literature Circles
Bryant,Stephanie A;
Colombian Applied Linguistics Journal , 2005,
Abstract: this article, reflecting a sociocultural perspective and connections to current research, presents a discussion about the importance of engaging latino children in literature circle discussions using culturally appropriate, meaningful, and relevant children's literature in classrooms in the united states. in addition, teachers are encouraged to be reflective practitioners and to consider a "funds of knowledge" perspective by taking time to understand the literacy practices of the families at home and how they may contribute to success in school for latino children.
Slice Implies Mutant Ribbon for Odd, 5-Stranded Pretzel Knots
Kathryn A. Bryant
Mathematics , 2015,
Abstract: A pretzel knot $K$ is called {\it odd} if all its twist parameters are odd, and {\it mutant ribbon} if it is mutant to a ribbon knot. We prove that the family of odd, 5-stranded pretzel knots satisfies a weaker version of the Slice-Ribbon Conjecture: All slice, odd, 5-stranded pretzels knot are {\it mutant ribbon}. We do this in stages by first showing that 5-stranded pretzel knots having twist parameters with all the same sign or with exactly one parameter of a different sign have infinite order in the topological knot concordance group, and thus in the smooth knot concordance group as well. After fixing the genericity condition that all twist parameters be greater than or equal to three in absolute value, we show that any odd, 5-stranded pretzel knot with zero pairs or exactly one pair of canceling twist parameters is not slice.
Cognitive Functioning and Insulin Regulation in Obese Youth  [PDF]
Christine A. Limbers, Jason Steadman, William Bryant, Matthew Stephen
Open Journal of Medical Psychology (OJMP) , 2014, DOI: 10.4236/ojmp.2014.31005
Abstract: Background: There are data that suggest adiposity is associated with diminished cognitive functioning in adults and youth, independent of related co-morbidities. Little is known about the pathophysiological mechanisms associated with cognitive function in obese youth. The objective of the present study was to assess the associations among cognitive functioning and insulin regulation in a sample of obese youth. Methods: The sample consisted of 30 obese, non-diabetic youth (BMI > 95th percentile) ages 6-16 years (mean age = 12.60 years) referred to an outpatient pediatric endocrinology clinic. Youth were administered the Wechsler Abbreviated Scale of Intelligence (WASI) and Wide Range Assessment of Memory and Learning (WRAML-2). Results: Verbal memory, attention/concentration, and intelligence scores were similar across obese youth with elevated insulin levels and normal insulin levels. Obese youth with elevated insulin levels had lower scores in visual memory, with a medium effect (effect size = 0.51). Fasting insulin levels were not associated with any of the four cognitive domains in the multiple linear regression analysis (P > 0.05). Conclusions: These data provide preliminary evidence that visual memory may be impacted in obese youth with insulin resistance. Longitudinal studies examining insulin regulation, cognitive functioning, and weight status over time are needed.
Oxytocin Enhances Social Persuasion during Hypnosis
Richard A. Bryant, Lynette Hung
PLOS ONE , 2013, DOI: 10.1371/journal.pone.0060711
Abstract: It has long been argued that hypnosis cannot promote behaviors that people will not otherwise engage in. Oxytocin can enhance trust in others, and may promote the extent to which a hypnotized person complies with the suggestion of a hypnotist. This double-blind placebo study administered oxytocin or placebo to high hypnotizable participants (N = 28), who were then administered hypnotic suggestions for socially unorthodox behaviors, including swearing during the experiment, singing out loud, and dancing in response to a posthypnotic cue. Participants who received oxytocin were significantly more likely to swear and dance than those who received the placebo. This finding may be interpreted in terms of oxytocin increasing social compliance in response as a function of (a) increased trust in the hypnotist, (b) reduced social anxiety, or (c) enhanced sensitivity to cues to respond to experimental expectations. These results point to the potential role of oxytocin in social persuasion.
Counselling a Woman Traumatized by Severe Abuse  [PDF]
Jodi Bryant
Psychology (PSYCH) , 2014, DOI: 10.4236/psych.2014.57083
Abstract:

The manuscript is a case report on a newly married Christian wife and mother of 3 children who sought help at a college counselling service for substance dependence and marital problems. Her past sexual trauma had manifested as severe traumatic reactions, which had contributed to a chronic emotionally distressed life, sexual promiscuity, and substance dependence, and she was unable to function appropriately in most spectrums of vitality. After the case issues and counselling approaches were researched, family members attended 11 Christ-centered or Spirituotherapy counselling sessions during which theistic and CBT interventions were used. The client gained insight into her past and current issues; grew spiritually; decreased her substance use; gained better communication skills, parenting, and coping methods; maintained a part-time job; and learned relapse prevention and management strategies. It was recommended that she continue theistic counselling.

Boston Naming Test: Gender Differences in Older Adults with and without Alzheimer’s Dementia  [PDF]
James R. Hall, Hoa T. Vo, Leigh A. Johnson, April Wiechmann, Sid E. O’Bryant
Psychology (PSYCH) , 2012, DOI: 10.4236/psych.2012.36068
Abstract: The study clarifies the relationship between gender and performance on the BNT by controlling for the effects of demographic and health risk factors. Participants were 468 outpatient individuals (153 diagnosed with probable Alzheimer’s Disease (AD) and 318 cognitively intact) enrolled in the Texas Alzheimer’s Research and Care Consortium cohort. Participants under went evaluations including medical examination, interview, neuropsychological testing, and blood draw. The neuropsychological assessment consisted of the Wechsler Digit Span, Logical Memory, and Visual Reproduction, along with the Trail Making Test, Boston Naming Test (60-item version), verbal fluency (FAS), and the Geriatric Depression Scale (GDS-30).To control for severity of cognitive impairment only mild AD as shown by a CDR global score of 0.5 or 1.0 were used. Control males outperformed females (F = 10.81, p < .000, ES = .20). AD males also performed significantly better than AD females (F = 17.13, p < .000, ES = .25). Gender differences remain after covarying for estimated IQ, age, education, and presence of hyperlipidemia and hypertension. Overall, within-group and between-group comparisons support prior findings that males perform significantly better compared to females on the BNT even after controlling for health and level of decline. Findings have implications for clinical practice and prospective test norm considerations.
Relaxometric Investigation of Functional Group Placement on MnTPP Derivatives Supports the Role of the Molecular Electrostatic Potential Maps as a Tool to Design New Metalloporphyrins with Larger Relaxivities
L. Henry Bryant,Gustavo A. Mercier
International Journal of Molecular Sciences , 2001, DOI: 10.3390/i2030140
Abstract: We report the T1 and T2 NMR (nuclear magnetic resonance) dispersion profiles for a new manganese porphyrin [MnT(2-C)PP] which has an anionic carboxylate group in the ortho position of the phenyl rings on the metalloporphyrin. Previous MEP (molecular electrostatic potential) maps indicated that this judicious derivatization could result in increases in the observed relaxation efficiency. Relaxometric investigations experimentally confirm about a 20 % increase in the relaxation efficiency at clinically relevant field strengths for MnT(2-C)PP compared to the most efficient metalloporphyrin previously reported MnT(4-S)PP. This result supports the hypothesis that electrostatic forces are relevant to the relaxivity of this family of compounds and that the MEP may be used as a tool to design new agents with even larger relaxivities.
Geomagnetic activity forcing of the Northern Annular Mode via the stratosphere
D. R. Palamara ,E. A. Bryant
Annales Geophysicae (ANGEO) , 2004,
Abstract: We consider various aspects of the link between solar-modulated geomagnetic activity and the Northern Annular Mode (NAM). Our results indicate that the geomagnetic forcing of atmospheric circulation in the Northern Hemisphere is temporally and seasonally restricted, modulated by the Quasi-Biennial Oscillation (QBO), and reliant on stratosphere-troposphere coupling. When the data are restricted to January values after 1965, for years in which the January QBO is eastwards, the correlation coefficient between the geomagnetic AA index and the NAM is 0.85. These results can account for many of the enigmatic features of Northern Hemisphere circulation. Key words. Meterology and atmospheric dynamics (general circulation, climatology)
Historic tsunami in Britain since AD 1000: a review
S. K. Haslett,E. A. Bryant
Natural Hazards and Earth System Sciences (NHESS) & Discussions (NHESSD) , 2008,
Abstract: The British coast is not considered at particular risk from tsunami, a view that is supported by a number of recent government reports. However, these reports largely ignore some written historic records that suggest southern Britain has experienced a number of events over the past 1000 yrs. This study briefly assesses these records and recognises four groups of events: 1) sea disturbance and coastal floods in southeast England linked to earthquakes in the Dover Straits (e.g. 1382 and 1580), 2) far-field tsunami reaching the coast of the British Isles, for example, from earthquakes along the Azores-Gibraltar Fault Zone offshore Portugal (e.g. 1755), 3) tsunami associated with near-coastal low magnitude earthquakes (e.g. 1884 and 1892), and 4) a flood event in AD 1014 that has been linked to comet debris impact. The seismogenic events range from minor water disturbance, through seismic seiching, to small and "giant" waves, suggesting near-coastal, low-magnitude, shallow earthquakes may be capable of triggering disturbance in relatively shallow water, as supported by similar occurrences elsewhere, and that the British tsunami risk requires a more careful evaluation.
Effect of Feed and Air Temperature on Optimum Egg Size and Profits During Phase 1 of Bovans White Hens
D.A. Roland,Sr.,M. Bryant
International Journal of Poultry Science , 2008,
Abstract: Two experiments were conducted to determine the most economical protein and lysine levels to feed laying hens during Phase I (weeks 21-36) of the laying cycle in order to optimize egg weight and profits when hens were exposed to warm (25.6 °C Average in Exp. 1) and cool temperatures (20.0 °C average in Exp. 2). In both experiments, nine hundred sixty 21-weeks old hens were randomly divided into six groups of 160 hens per group and fed one of six diets. Diets were formulated based on protein and lysine. Three diets formulated on protein contained 17.00, 18.70 and 20.80% protein and 0.90, 1.02 and 1.17% lysine, respectively. Three diets formulated based on lysine contained 0.75, 0.83 and 0.92% lysine and 14.98, 16.19 and 17.34% protein, respectively. Response criteria were egg production, feed consumption and egg weight. Neither diet nor method of formulation had an effect (p>0.05) on any response criteria other than egg weight in Exp. 1 and Exp. 2. In both experiments, egg weight increased (p<0.05) as the Lysine (or protein) content increased. Using an economic analysis with egg and feed prices at the time of the study, Bovans White hens required 1,076 mg lysine, 750 mg total sulphur amino acids (TSAA), 19.1 g protein and 264 kcal ME/hen/d for optimum profits during Phase I under warm conditions and 1,100 mg Lysine, 789 mg TSAA, 20.22 g protein and 310 kcal ME/hen/d during Phase I for maximum profits when kept under cool temperatures. Because feed and egg prices vary, there can be no fixed lysine (protein) requirement for optimal profit.
