在低频区具有大带隙的长方晶格二维光子晶体

利用降低光子晶体的对称性来提高绝对禁带宽度，在长方网格边上加正方介质柱而构成像素型长方晶格二维光子晶体，用快速平面波展开法计算其能带结构，通过参数优化，在低频区找到最大绝对禁带宽度△ωe=0．119ωe（ ωe=2πc／a，a为晶格常数，c为光速），绝对禁带中心频率ωmid=0．829ωe，△ω/ωmid=14，4％。

(Trans)lating Identity: Exploring Discursive Strategies for Navigating the Tensions of Identity Gaps

This study explored the formation and expression of gender identity among 19 self-identified transgender individuals through the use of qualitative, in-depth interviews. Through the lens of the Communication Theory of Identity (CTI), we examined how trans* individuals form and perform gender identity, the tensions produced between identity frames, and the discursive strategies used to navigate those tensions. We identified the manifestation of three specific identity gaps: personal-enacted, personal-relational, and enacted-relational. Furthermore, we discovered four discursive strategies previously recognized for navigating tensions that emerge from identity gaps: closeted enactment, passing, disengagement, and label changing, and we identified a fifth discursive strategy—hyper-engagement—used to navigate these tensions. Results revealed that these identity layers and discursive strategies collaboratively manifest and coalesce in response to specific communicative contexts. Our results are discussed within the resounding call for greater understanding of trans* identity formation and expression.

An Education Worth Having: The Aspirations and the Development of the Whole Education Network in England

The Whole Education National Network is a dynamic national not-for-profit partnership of schools and organisations that believe that all children and young people are entitled to an education that supports the development of wider skills, qualities and characteristics to enable them to thrive in life, learning and work, as well as conventional academic achievement. The article outlines the background to the development of the growing network of some 150 schools plus partner organisations and its core aims. It then considers what the Network is achieving and what it is learning about its approach as it grows. It offers and is seeking to embed and sustain an approach to school development that is ‘values-led, evidence-informed and impact-focused’. It is also predicated on a commitment to and belief in peer-to-peer collaboration, inspired and encouraged by the work of leading academics, thinkers and practitioners. Whole Education is also a response to what many observers and commentators identify as a weakness of the English and many other systems: the gap between the outcomes achieved by the more disadvantaged and other students. Part of its moral purpose is to help to narrow that gap, underpinned by a belief that focusing on immediate outcomes and test scores is not enough on its own. The Network operates in the belief that it will only be through the commitment to an entitlement to a ‘whole education for all’ that any school or system will truly narrow the gap and make a real difference to the life-chances of all young people. School leaders and schools that have gravitated towards Whole Education seek like minds to share and, more importantly, develop both their thinking and strategies employed to help achieve their goals. At the heart of the change model underpinning Whole Education is the development of effective communities of practice that develop professional capital and unleash the creativity of teachers. Creating, embedding and sustaining a national self-funded school-led network committed to achieving longer-term aspirations rather than immediate needs is both inspiring and challenging. The pressure to respond to short-term targets in terms of student outcomes and accountability pressures has meant that the energy and resource tend to be focused on the immediate rather than the medium- or longer-term needs. Whole Education provides a powerful example of how schools that share common aspirations can seize the agenda, have real impact on students and demonstrate the potential of a self-improving school system.     

基于区域差异视角的江苏省城乡收入差距研究

本文以存在梯度区域发展差异的江苏省2000-2012年的相关数据为基础,研究了经济增长、人力资本、财政支出及农业税改革等因素对城乡收入差距的影响。研究发现：各因素对江苏省区域城乡收入的影响存在差异性,除经济增长与城乡收入分配呈现倒“U”型特征的共性外,不同区域人力资本、财政支出及农业税改革与城乡收入差距呈现较为复杂的关系。文章最后对差异性结果产生的原因进行了探索性解释。     

伦敦奥运会男篮比赛评析* ——兼论中国男篮差距

通过对伦敦奥运会男篮比赛分析发现,来源于欧美职业篮球联赛队员数量决定各队竞技实力,体现各国运动员国际流动与交融发展新趋势;欧、美球队呈现"高、快、灵、准、全、悍、变、星"的进攻特征及防守"以球权争夺为核心,球、人、区、时空兼顾"的先进理念;当前世界篮球区域发展不均衡,美洲占据竞技优势,欧洲整体水平高,亚、非洲实力弱,呈欧美全面抗衡格局;中国男篮竞技水平和成绩下滑明显,运动员身体机能指标和得分、失分、投篮次数、命中率、篮板球、助攻、失误、抢断指标与世界强队存在显著性差异(P﹤0.05),盖帽、犯规无显著性差异(P0.05),表现出个人能力、技战术风格、整体攻防与世界强队全方位差距,并呈逐步拉大趋势。

Diagnostic Dilemma of HbA1c Detection in Presence of a Hemoglobinopathy: A Case Report

We report a case of a diabetic, heterozygote with near normal hematology, marginally low level of hemoglobin A₂(HbA₂) having an increased level of hemoglobin F(HbF) that was pancellularly distributed among the red cells. BioRad DiaSTAT measurements gave a high glycated hemoglobin A1c(HbA1c) of 31.5% and the BioRad Variant analyzer recorded an HbA1c value which was very low, in discordance with the detected blood glucose levels. Flow cytometry and polymerization chain reaction (PCR) based studies were carried out which revealed the case to be that of the common hereditary persistence of fetal hemoglobin (HPFH)-3, an Asian Indian mutation. Fructosamine estimation and HbA1c by Boronate affinity chromatography were able to resolve the discordant value detected and was able to confirm the diabetes status. The case would have been a diagnostic dilemma, if reported without correlation.
