接触式低温固定中样品内部传热过程的分析

建立了用于电子显微镜生物样品制备的接触式低温固定法中的传热过程模型,并求得了一维常物性条件下的精确解。讨论了样品内部冷却速率的一些变化规律及其与样品初始温度和固化温度的关系,为实际的低温固定操作提供了理论指导。     

张闻天与西安事变中的“二·二事件”

西安事变和平解决后,蒋介石背信弃义,扣押了送他回宁的张学良。正当西安的“三位一体”积极寻求解救张学良的方案时,东北军内出现了武力解救与和平解救的岐见。１９３７年２月２日,主战派头头枪杀了主和派将领王以哲等４人,史称西安事变中的“二·二事件”。本文通过对张闻天在“二·二事件”发生前后的言行考察和研究,揭示了这一事件的性质、真相及经验教训     

西安事变和平解决的主要因素

西安事变的和平解决成为国共两党由内战到合作杭日时局转换的枢纽,促成西安事变和平解决的主要因素有：一、中国共产党以民族大计为重,从中协调。二、蒋介石被迫反省,改弦更张。三、张学良、杨虎城两位将军无私无畏,肝胆相照。四、宋氏兄妹从中斡旋,入情入理。西安事变得以和平解决是诸多因素促成的结果,缺少任何一个方面,西安事变的和平解决都是不可能的。     

The Resilient Survivor—A Student Social Worker's Journey on Placement

This paper represents the continuation of my ‘personal and professional journey’ from social work student to social work practitioner focusing on my first Practice Learning Opportunity (PLO). Recognising the potential impact of childhood sexual abuse (CSA) in a classroom environment is as important as the potential impact on actual practice learning and practice. This is salient in the real world of social work practice as the potential misuse of a painful childhood experience has greater ramifications. Utilising the ideas and assumptions of social constructionism (including context and multivocality) the significance of silence from social work educators shall be examined in relation to self-disclosure as a means of aiding PLO learning and practice. This paper will also focus on the concept of critical reflection and its significance in exploring the transferability of a childhood experience such as CSA and personal and professional dilemmas regarding self-disclosure. This paper concludes by highlighting areas for consideration for both students and social work educators and conveys an important message regarding the importance of communication between students and social work educators.     

Effects of critical incident tasks on the intercultural competence of English non-majors

ABSTRACT

In this internationalised world, graduate employability in terms of intercultural communication skills needs to be taken into account in higher education. The present study aims to explore the effects of critical incident task instruction on English non-majored undergraduates’ intercultural competence. One group of students received ten weeks of instruction with one critical incident task per week and another group received standard English classes. Data were collected from the students’ pre- and post-test. The results showed a significant and strong effect of the intervention with critical incident tasks. Implications for educational practice are presented for further teaching with critical incident tasks.     

Assumptions,conjectures, and other miracles: The application of evaluative thinking to theory of change models in community development

Unexamined and unjustified assumptions are the Achilles’ heel of development programs. In this paper, we describe an evaluation capacity building (ECB) approach designed to help community development practitioners work more effectively with assumptions through the intentional infusion of evaluative thinking (ET) into the program planning, monitoring, and evaluation process. We focus specifically on one component of our ET promotion approach involving the creation and analysis of theory of change (ToC) models. We describe our recent efforts to pilot this ET ECB approach with Catholic Relief Services (CRS) in Ethiopia and Zambia. The use of ToC models, plus the addition of ET, is a way to encourage individual and organizational learning and adaptive management that supports more reflective and responsive programming.     

Task-based learning approaches for supporting the development of social science researchers’ critical data skills

Conducting social science research is a complex process, and social science students face a number of learning challenges in order to develop their skills. Moreover, new sources and types of data including so-called big data are providing new opportunities for research, but also pose methodological challenges. In this article, we explore a task-based learning approach for teaching social science research methods. We draw on evidence from two case study learning tasks: (i) the collection and analysis of Twitter data; and (ii) designing and conducting a face-to-face and online survey. The students were guided to co-lead the tasks, apply their knowledge and then to critically reflect. The pedagogical framework of task-based learning provides opportunities to embed learning in new ways by integrating knowledge, practice and critical reflection. Task-based learning can create a dynamic learning environment and can empower students to develop their identities as researchers.     

战后国民政府涉港事务处置个案研究——以张添祥事件为例

太平洋战争期间,国民政府争取香港主权的努力遭遇挫折,战后英国重返香港,中国在涉港事务中试图积极应对,争取国家利权。1946年12月3日,中国内地与香港边境的文锦渡发生一起英军越界开枪事件,造成宝安县居民张添祥死亡,即＂张添祥事件＂。事件发生后,广东地方当局和民意机构主张强硬外交,积极组织援助;国民政府外交当局亦介入善后,在民意舆论的压力下展开外交维权。最终,张添祥事件不了了之。
