Sexuality education including lesbian, gay, bisexual, and transgender (LGBT) issues in schools

Publication date: Available online 12 October 2017 Source:Educational Research Review Author(s): Andreas Gegenfurtner, Markus Gebhardt Should children and adolescents be educated in school about gender diversity, including lesbian, gay, bisexual and transgender (LGBT) issues? This is a question many governments and educational policymakers discuss in their process of reforming relationships and sex education. However, these reform plans face resistance from parents, religious groups, and political parties. Specifically, opponents argue that (a) children who learn about LGBT issues in school will engage in same-sex practices or even become homosexual, bisexual, or trans* themselves; (b) schools force a particular view on children that stands in contrast to the heteronormative, religious, and/or political views of parents; and (c) teachers act as role models and change the sexual orientation and gender identity of their students. This systematic literature review aims to offer evidenced-based answers to these arguments on the grounds of biological, sociological, psychological, and educational research. First, twin studies and genome scans in behavioral genetics research unveil strong biological roots of sexual orientation and identity that will not change through inclusive sexuality education. Second, psychological and sociological research signals that heteronormativity, homosexuality non-acceptance, and negative attitudes toward LGBT people in general are associated with low...

The most intriguing abandoned settlements, from ancient ruins to modern ghost townsLast week laser scanning revealedthe true scale of the ancient city of Angamuco in western Mexico. The city, built around AD900, is thought to have had 100,000 residents and included pyramids, road systems, vegetable gardens and ball courts. It was a major centre for the Pur épecha people, rivals to the Aztecs. Both cultures collapsed in the 16th century when Europeans introduced typhoid-like diseases to which they had no immunity.Continue reading...

Publication date: Available online 24 February 2018 Source:Thermochimica Acta Author(s): Fiona C. Binks, Gabriel Cavalli, Michael Henningsen, Brendan J. Howlin, Ian Hamerton An epoxy resin based on the difunctional diglycidyl ether of bisphenol A (DGEBA) is reacted thermally in the presence of a series of 1,3-dialkylimidazolium based ionic liquids comprising the common cation (1-ethyl-3-methylimidazolium) and an anion (acetate, dicyanamide, or thiocyanate). Dynamic differential scanning calorimetry was used to analyse the formulations comprising DGEBA and the ionic liquid where it was revealed that the lowest and highest ...

Muiruri, Warintorn Thitsartarn, Xing Zhang, Beng Hoon Tan, Chaobin He In the effort to overcome the shortcomings such as brittleness and poor mechanical stability, and increase the competitive edge of renewable poly(lactic acid) PLA over conventional petroleum-based thermoplastics, silica rubber core-shell nanoparticles for effective PLA toughening were successfully synthesized by sequential ring opening polymerization (ROP). The core-shell structure was designed with silica as inner core, P(CL-mLA) as ‘...

Abdelhameed Bio-active synthetic fabrics based on polyester (PET) and Nylon were manufactured by in-situ formation of Cu-BTC metal organic framework (MOF). In-growth of Cu-BTC within fabrics was accomplished in one pot simple process. The scanning microscope, X-ray diffraction and infrared spectra were all confirmed the formation of Cu-BTC within fabrics structure and reflected the role of fabrics' building unit in the Cu-BTC preparation. The estimated contents of materials onto fabri...

Conclusion(s) This TMS/fMRI study evaluated a control condition that preserved many of the sensory features of TMS while reducing magnetic field entry. These findings support a relationship between single pulses of TMS and activity in anatomically connected regions, but also underscore the importance of using a sham condition in future TMS/fMRI studies.

Kurada, Tanmay, Sirshendu De Industrial oily water containing oil, grease and dust has been treated using stage-wise filtration, first by sand bed followed by cross-flow ultrafiltration hollow fiber membrane. The sand bed removes majority of suspended particles and reduces the turbidity from 13.6 NTU to 2.6 NTU. Effects of transmembrane pressure drop and cross flow rate on ultrafiltration performance were investigated. A transport phenomena based model under the framework of boundary layer theory was developed to quantif...

Abstract IntroductionTwin vaginal delivery presents a unique clinical challenge for obstetricians. The twin birth study demonstrated the safety of planned vaginal delivery regarding neonatal outcomes. However, that study lacked description of the risk factors associated with and the outcome of unplanned cesarean section. The aim of this study is to identify potential risk factors for cesarean section and delivery related neonatal morbidity and mortality in women with twin pregnancy attempting vaginal delivery. Material and methodsA retrospective cohort study including 1070 women with twin pregnancy that underwent a trial o...

(NEW YORK) — Thirteen years after building a state-of-the-art lab for the world’s most dangerous germs, the nation’s top public health agency is asking for more than $400 million to build a new one. Officials at the Centers for Disease Control and Prevention say the current lab building in Atlanta is quickly wearing down, and cannot be upgraded without shutting down the facility for years. The lab investigates deadly and exotic germs like Ebola, smallpox and dangerous new forms of flu.The agency disclosed its plans for a new lab on Friday. The CDC lab is one of only eight U.S. labs with the security and s...
