Impact of Flexible Seating on First Grade Reading Progression

Proponents of flexible seating options within the classroom claim this simple change will transform education, improve children\u27s engagement and learning, and renew classroom teaching. Opponents argue that such benefits are overstated because, currently, little evidence exists that eliminating desks and chairs improves learning and student engagement. In this study, the impact of flexible seating on first grade reading scores was examined and how it is implemented when teaching reading at the primary level. This quantitative research plan used the Fountas and Pinnell Benchmarking Kit to determine if students who chose the option of flexible seating during the reading block had differing scores than their peers using a tradition desk-chair or table-chair seating arrangement. The research was completed by collecting data from six first grade classrooms and a total of 103 students across the Rapid City Area School District. The research showed no difference in scores among the two groups as well as subgroups studied when an ANOVA was used to analyze the results. Further research of greater length of time, behavior analysis, and emotional impact based upon class size, teacher training, and years of experience would be beneficial to future study

Outcomes of a specialist weight management programme in the UK national health service: prospective study of 1838 patients

Objectives There is limited evidence on the effectiveness of weight management programmes provided within routine healthcare and inconsistent use of outcome measures. Our aim was to evaluate a large National Health Service (NHS) weight management service and report absolute and proportional weight losses over 12 months.<p></p> Design Prospective observational study.<p></p> Setting Glasgow and Clyde Weight Management Service (GCWMS), which provides care for residents of NHS Greater Glasgow and Clyde area (population 1.2 million).<p></p> Participants All patients who began GCWMS between 1 October 2008 and 30 September 2009.<p></p> Interventions Structured educational lifestyle programme employing cognitive behavioural therapy, 600 kcal deficit diet, physical activity advice, lower calorie diet and pharmacotherapy.<p></p> Primary and secondary outcomes measures Baseline observation carried forward (BOCF), last observation carried forward (LOCF) and changes in programme completers reported using outcomes of absolute 5 kg and 5% weight losses and mean weight changes at a variety of time points.<p></p> Results 6505 referrals were made to GCWMS, 5637 were eligible, 3460 opted in and 1916 (34%) attended a first session. 78 patients were excluded from our analysis on 1838 patients. 72.9% of patients were women, mean age of all patients at baseline was 49.1 years, 43.3% lived in highly socioeconomically deprived areas and mean weights and body mass indices at baseline were 118.1 kg and 43.3 kg/m2, respectively. 26% lost ≥5 kg by the end of phase 1, 30% by the end of phase 2 and 28% by the end of phase 3 (all LOCF). Weight loss was more successful among men, particularly those ≤29 years old.<p></p> Conclusions Routine NHS weight management services may achieve moderate weight losses through a comprehensive evidence-based dietary, activity and behavioural approach including psychological care. Weight losses should be reported using a range of outcome measures so that the effectiveness of different services can be compared

The Analysis of Cyanide and its Metabolites in Biological Samples

Cyanide is a toxic chemical that may be introduced to living organisms as a result of both legal and illicit uses of cyanide. Exposure to cyanide can be verifi ed by analyzing cyanide or one of its break-down products from biological samples. This verifi cation is important for medical, law-enforcement, forensic, research, and veterinary purposes. This review will identify common problems associated with the analysis of cyanide and its metabolites, discuss current bioanalytical techniques used for verifi cation of cyanide exposure, and briefl y address the metabolism and toxicokinetics of cyanide and its break-down products in biological systems

Fighting Anti-Gay Abuse in Schools: The Opening Appellate Brief of Plaintiff Jamie Nabozny in \u3cem\u3eNabozny V. Podlesny\u3c/em\u3e

In Nabozny v. Podlesny, 92 F.3d 446 (7th Cir. 1996), a case of first impression, the Seventh Circuit Court of Appeals recognized the constitutional right of a gay male public school student to equal protection from anti-gay harassment and assaults. The court held that Jamie Nabozny had stated equal protection claims against his school district and three school principals for gender and sexual orientation discrimination based on allegations that, because he is gay and a boy, defendants had failed to afford him the same kinds of protection given to other harassed students. At trial on remand a jury found the three school principals liable for intentional discrimination

tert-Butyl 2-methyl-2-(4-nitro­benzo­yl)propanoate

The title compound, C15H19NO5, is bent with a dihedral angle of 61.8 (2)° between the mean planes of the benzene ring and a group encompassing the ester functionality (O=C—O—C). The dihedral angle of 0.8 (2)° between the mean planes of the nitro group and the benzene ring indicates near coplanarity. In the crystal, each mol­ecule is linked to four adjacent mol­ecules by weak C—H⋯O hydrogen-bonding inter­actions. Both benzene H atoms ortho to the ketone O atom form C—H⋯O hydrogen bonds with the keto O atoms of two neighboring mol­ecules (of the keto and ester groups, respectively), and the two other inter­actions involve the H atoms from a methyl group of the dimethyl residue, displaying C—H⋯O inter­actions with the O atoms of the nitro groups. These four inter­actions for each mol­ecule lead to the formation of two-dimensional sheets with a hydro­philic inter­ior, held together by weak hydrogen-bonded inter­actions, and a hydro­phobic exterior composed of protruding methyl groups which interst­ack with the methyl groups in adjacent sheets

The Influence of Signaling Conspecific and Heterospecific Neighbors on Eavesdropper Pressure

The study of tradeoffs between the attraction of mates and the attraction of eavesdropping predators and parasites has generally focused on a single species of prey, signaling in isolation. In nature, however, animals often signal from mixed-species aggregations, where interactions with heterospecific group members may be an important mechanism modulating tradeoffs between sexual and natural selection, and thus driving signal evolution. Although studies have shown that conspecific signalers can influence eavesdropper pressure on mating signals, the effects of signaling heterospecifics on eavesdropper pressure, and on the balance between natural and sexual selection, are likely to be different. Here, we review the role of neighboring signalers in mediating changes in eavesdropper pressure, and present a simple model that explores how selection imposed by eavesdropping enemies varies as a function of a signaling aggregation\u27s species composition, the attractiveness of aggregation members to eavesdroppers, and the eavesdroppers\u27 preferences for different member types. This approach can be used to model mixed-species signaling aggregations, as well as same-species aggregations, including those with non-signaling individuals, such as satellites or females. We discuss the implications of our model for the evolution of signal structure, signaling behavior, mixed-species aggregations, and community dynamics

tert-Butyl 2-methyl-2-(4-methyl­benzo­yl)propanoate

The title compound, C16H22O3, is bent with a dihedral angle of 75.3 (1)° between the mean planes of the benzene ring and a group encompassing the ester functionality (O=C—O—C). In the crystal, the mol­ecules are linked into infinite chains held together by weak C—H⋯O hydrogen-bonded inter­actions between an H atom on the benzene ring of one mol­ecule and an O atom on the ketone functionality of an adjacent mol­ecule. The chains are arranged with neighbouring tert-butyl and dimethyl groups on adjacent chains exhibiting hydro­phobic stacking, with short C—H⋯H—C contacts (2.37 Å) between adjacent chain
