Because the localized plasmon resonance modes, energies and strengths are strongly dependent on the dielectric function of the surrounding environment, the substrate is expected to largely affect the plasmonic properties of supported metal nanocrystals. Therefore, understanding the effects of the substrate on the…

Author: Zhong, Baichang; Wang, Qiyun; Chen, Jie Description: Pair programming (PP) is a usefulness approach to fostering computational thinking (CT) for young students. However, there are many factors to impact the effectiveness of PP. Among all factors, the social factors are often ignored by researchers. Therefore, this study aimed to explore the impact of two social factors (gender and partnership) on PP in a primary school setting. To that end, we conducted PP experiments in four classes from the sixth grade in a Chinese primary school. The research results indicated:…

Author: Dyba, Tore; Arisholm, Erik; Sjoberg, Dag I. K.; Hannay, Jo E.; Shull, Forrest Description: Pair programming has many claimed benefits over individual programming. Researchers examined all 15 existing studies of pair programming to determine whether working in pairs is more effective than working individually. Subject headings: Programming profession; Resource management; Educational institutions; Application software; Europe; North America; Time measurement; Code standards; Measurement standards; Pair programming; Duration; Effort; Quality; Code Publication year: 2007 Journal or book title: IEEE Software Volume: 24 Issue: 6 Pages: 12-15 Find the full text: https://ieeexplore.ieee.org/abstract/document/4375233…

Description: BACKGROUND: Operating rooms are major contributors to a hospital’s carbon footprint due to the large volumes of resources consumed and waste produced. The objective of this study was to identify quality improvement initiatives that aimed to reduce the environmental impact of the operating room while decreasing costs. STUDY DESIGN: A literature search was performed using PubMed, Scopus, CINAHL, and Google…

Author: Taylor, Richard J. K. Description: Conjugate additions reactions between organocopper reagents and ?,?-unsaturated carbonyl compounds are now well established synthetic procedures. This article reviews reactions in which the intermediate enolates are trapped with electrophilic reagents to give ?-substituted enol derivatives or ?,?-disubstituted ketones. The synthetic potential of these products is highlighted. 1. Introduction: Scope and Limitations 2. Silylation and Related O-Enolate Trapping Reactions 3. Enolate Acylation 4. Enolate Alkylation 5. Reactions of Enolates with Michael Acceptors 6. Reactions of Enolates with Aldehydes and Ketones 7. Reactions of Enolates with Miscellaneous…

Author: Brysk, Alison; Mehta, Aashish Description: Despite two decades of rapid global economic growth and social modernization, including increases in gender equity, levels of violence against women remain stubbornly high. Moving beyond conventional liberal views, a growing literature has identified how structural change and conflict associated with economic development can exacerbate women’s physical insecurity. We examine the relationship between development patterns and variation in the Physical Security of Women index—the best available cross-national indicator—to fill the gap in emerging ethnographic, case and survey-based accounts with systematic cross-country assessment. We find…
