Gay–straight alliance (GSA) members’ engagement with sex education in Canadian high schools

This paper offers an examination of gay–straight alliance (GSA) members’ engagement with sex education, sexual health, and prejudice and discrimination in Canadian public high schools. It explores how five students’ (four straight and one gay-identifying) participation in GSAs served as a springboard for learning about and challenging stereotypes; prejudice; and discrimination directed at lesbian, gay, bisexual, trans, and queer/questioning (LGBTQ) people. Queer theory provided the theoretical underpinnings of the study, offering a lens through which to examine the heteronormative underpinnings of education, and a means to interpret how homophobic discourses circulate in school and society. Empirical data were obtained via observational notes from visits to nine GSAs and semi-structured interviews with the five GSA members. Findings suggest that straight allies can use their heterosexual privilege to address LGBTQ issues with their peers. Through GSA involvement, participants learned to interrogate and combat stereotypes about LGBTQ people and HIV-related myths, as well as to engage in queer discussion and political action.     

内江市公园绿地土壤重金属Cu分布研究

对内江市大干园、塔山公园、大洲广场、人民公园0-20cm土层中的Cu、有机质和pH值进行研究,以农耕地为对照,结果表明：（1）土壤中Cu含量塔山公园显著低于人民公园,各公园绿地与农耕地差异不显著,各公园绿地土壤Cu为国家一级标准;（2）不同坡位Cu含量总体表现为：下坡＞中坡＞上坡;（3）各绿地土壤pH值为7.4～8.33,有机质含量差异不显著;（4）公园绿地土壤中Cu含量与有机质、pH值之间相关性不显著.     

商洛野生地木耳营养成分及其重金属检测

为了探讨商洛市不同区域(北部区域、中部区域、南部区域)野生地木耳中多糖含量、蛋白质含量的差异,采用水提醇沉法、凯氏定氮法分别对商洛市不同区域野生地木耳中多糖含量和蛋白质含量进行了测定,并选用石墨炉原子吸收光谱法和原子荧光光度法分别测定了样品中铜、铅以及砷的含量。结果表明:三个区域中,北部区域样品所含的多糖含量和蛋白质含量最高,分别占干重的5.89%和18.97%;原子吸收法测得南部区域样品和中部样品中铅、砷含量最低,分别为0.2678、0.6953 mg·kg-1。

金属叶绿素衍生物的制备及光谱研究进展

过渡金属Cu、Fe、Co、Ni、Zn、Mn的可溶性盐类以及稀土金属La、Ce、Pr、Nd、Sm氧化物在HClO4中溶解后在一定条件下与脱镁叶绿素合成过渡/稀土金属叶绿素;过渡金属叶绿素皂化可形成可溶性过渡金属叶绿酸盐;可溶性过渡金属叶绿酸盐又可与某些金属离子反应形成难溶性的过渡金属叶绿酸盐。通过研究这些金属叶绿素配合物的Fourier变换红外光谱、紫外可见光谱（UV-Vis）并与脱镁叶绿素或脱镁叶绿酸对比,对其谱图的数据进行了分析。     

提高高职金属工艺学教学趣味性的几点做法

高职金属工艺学（简称＂金工＂）课程因其基本概念多,内容零散,逻辑性不强,有些内容比较抽象,使学生学习起来感到枯燥无味,难于理解,因而学习兴趣不浓。针对这一问题,通过运用直观形象的教学手段、利用生动的生产和生活事例、穿插有趣的故事情节、引用带有激励性的信息资料、使用生动的语言和形象的动作、运用贴切恰当的比喻、运用简洁的歌谣、设计行云流水的导入（过渡）等手段,提高教学的趣味性,收到较好效果。     

Managing Patient-centered Communication across the Type 2 Diabetes Illness Trajectory: A Grounded Practical Theory of Interactional Sensitivity

This article uses the theoretical and methodological framework of Grounded Practical Theory (GPT) to provide a lens for analyzing and interpreting discourse as a situated form of social action in routine Type 2 diabetes visits. Drawing on a total data-set of 400 audio-recorded routine visits, we randomly selected 55 visits for qualitative analysis. In this article, we use Conversation Analysis to document communication techniques, which we in turn use as evidence to ground our claims within the GPT framework. We use two single cases of interaction to analyze communication techniques physicians use when recommending a change from oral medication to insulin. We argue treatment intensification is a key moment in health communication to reflect about patient centeredness because physicians can find themselves in an interactional dilemma: while insulin may effectively help control unstable disease, an insulin recommendation may simultaneously counter patient values and treatment preferences. Our analysis suggests that physicians use what we call interactional sensitivity to balance medical need and patient preferences when making medical decisions by tailoring their communication according to the local situation and the patient's larger illness trajectory. We propose that interactional sensitivity is a type of communication work and a quality of patient-centered communication characterized by the theoretical relationship between tailoring communication to the contingencies of the local interaction and the global illness trajectory. Overall, this article contributes to health communication scholarship by proposing a normative model for reflecting on how physicians negotiate challenging interactions with patients during routine chronic illness visits.     

The Donkey of the Prophet in Shī‘ite Tradition

The present study examines the treatment of the Prophet's mount in Shī‘ite tradition. We discuss the different opinions concerning the ass's name, ‘Ufayr or Ya‘fūr and present various traditions concerning utterances spoken by it, including utterances addressed to the Prophet, and other cases of human-like behaviour on its part, such as an ability to distinguish Muslims from Jews. We then go on to compare the Prophet's ass to those of other prophets, and find a number of similarities between them, in particular their ability to speak a human language. We also discuss the ass's death, which according to Shī‘ite tradition was by suicide, occasioned by the ass's fear following his master's death that someone else, not a prophet, would use it as a mount. We compare the Prophet's ass to those of Noah, and Solomon's Hoopoe, and show how Shī‘ite tradition has focused on similarities among them and utilized those to support the idea of the Imāmate as the Prophet's legacy in Shī‘ite doctrine. We further discuss the preference which Shī‘ite Imāms had for asses as against other mounts, a preference based on their wish to follow in the Prophet's footsteps.     

Portugal and the Mediterranean trade: A Prelude to the discovery of the “new world”

Before the century of great discoveries, and during most of the fifteenth century, the Portuguese developed important commercial activity in the Mediterranean. This is the central issue of this article as seen through two themes: the first is an assessment of the Portuguese organization of Mediterranean trade, with special attention given to the foodstuffs which were, and continued to be, a feature of such trade; and second, is to observe how Portuguese faced competition from others nations’ merchants in the region. The study of these two aspects will provide a better understanding of the re-orientation of Portuguese trade towards the Atlantic.
