非对称情况下的多物品拍卖

本文讨论当投标人之间存在不同的预算约束时两物品的序贯增价拍卖,对于物品之间不同的关系(互补、替代或者不相干的关系),物品价值大小的不同及与预算大小之间的关系,在一个简单的完全信息模型下,我们分不同情况讨论投标人的均衡出价策略,并发现对卖方来说,先拍卖价值高的物品是弱占优的策略。

基于iCARE理论的《大学英语》课程定位研究与教改实践

《大学英语》是高校一门重要的公共基础课,厘清课程性质是推进教学改革的基础。在梳理不同时期《大学英语》教学大纲有关规定,借鉴国外高校现代语言课程定位基础上,提出《大学英语》课程定位是EGP,提高"交互密度"是保证学习效率和效果的关键。河北科技大学在多年教改实践基础上,创建了iCARE教学理论,并从六个方面推进《大学英语》课程改革,形成具有校本特色的《大学英语》教学模式,取得良好教改成效。     

西部普通高校公共英语教师激励现状调查分析

为探究西部普通高校对大学公共英语教师管理中的激励问题,以四川D大学、贵州S大学、重庆L大学和云南W大学为例,采用问卷调查法和访谈法对西部四所普通高校公共英语教师的激励现状进行了量化和质化研究.根据调查结果,总结出制约西部普通高校公共英语教师激励作用的因素包括几个方面:第一,高校管理行政化严重影响科学激励建立;第二,职称评定体系无法发挥激励作用;第三,激励制度缺乏公平性;第四,教师培训没有得到合理关注;第五,缺乏有效的考核方式.基于此,西部普通高校管理者应该充分考虑高校公共英语教师的激励特征,构建有效的公共英语教师激励,实现管理的优化.     

习近平建设海洋强国重要论述研究

习近平建设海洋强国重要论述经历了率先发出“向海进军”号召、明确提出海洋经济强省建设、庄严宣告海洋强国建设三个阶段。习近平建设海洋强国重要论述主要包括发展海洋经济、保护海洋环境、创新海洋科技、维护海洋权益等。习近平建设海洋强国重要论述具有三个鲜明的特点：在海洋强国建设“目的性”上做到了为国富强与为民谋利的统筹;在海洋强国建设“方法论”上做到了矛盾论和系统论等方法的统筹运用;在海洋强国建设“治理观”上实现了国际治理与国家治理的统筹。习近平建设海洋强国重要论述具有重要的区域意义——指导有关沿海省份创建海洋强省示范区、国家意义——强力推进海洋强国建设并取得了重大突破、世界意义——为全球海洋治理提供“中国方案”和“中国经验”。     

Socio‐economic stratification of English in globalized landscapes: A market‐oriented perspective

Globalization has dramatically altered the urban societies of Amsterdam and Brussels over recent decades, with intensified socio‐economic inequality, unprecedented levels of multilingualism and the increasing importance of English. In this paper, I examine the use of English in the linguistic landscape of socio‐economically stratified commercial shopping streets in these two second‐tier global cities. I adopt a market‐oriented, contextualized approach to quantitative and qualitative variability in how English emerges in these particular commercial ‘linguistic markets’. McDonaldization in midscale shopping streets occurs alongside downscale and upscale uses of English which are more susceptible to local commercial dynamics, in particular in Brussels. As such, global English in these single city contexts emerges as a heterogeneous and scaled phenomenon shaped by specific local commercial and linguistic market conditions.     

A Security Model and Legal Guarantee for Chinese Maritime Shipping: As Exemplified in the Response to Piracy along the 21st Century Maritime Silk Road

The Belt and Road Initiative is an important decision for the great rejuvenation of the Chinese nation. Maritime security has a significant place in this process. In recent years, there have been frequent violent terrorist incidents at sea, including piracy, armed hijackings and terrorist attacks, posing a dire threat to both international and Chinese maritime transport interests and seriously challenging the fulfillment of the maritime part of the “Belt and Road Initiative.” Five direct measures can be taken to protect ocean shipping from violence at sea. One example is the defensive measures taken against the Somali pirates. The employment of armed guards from professional security companies on board ship is an effective model for guaranteeing maritime security; it not only meets the standards of international law, but is also legally permitted in many developed countries and regions, and is thus strategically significant for overall Chinese maritime security. In the Chinese context, this model carries its own legal risks. We should embrace a new approach to national security law, strengthen legal guarantees and make concerted efforts to provide warship (military aircraft) escorts to jointly build an optimum model of Chinese maritime security in order to ensure the realization of core Chinese maritime interests.     

Infusing Career Development to Strengthen Middle School English Language Arts Curricula

An approach is presented for strengthening middle school standards‐based English language arts (ELA) classroom instruction by infusing theory‐ and research‐supported career development constructs and practices. Over an 8‐week period, 90 urban 7th graders participated in an integrated ELA–career development curriculum. Career agency emerged as an important construct for students. It was related to key markers of ELA achievement (i.e., standardized test scores, grades, and positive change in 6th‐ to 7th‐grade test scores) and elaborated on in nuanced ways by students in their written narratives. Four themes related to career agency were identified in student writings: time perspective, challenges of self‐direction, career development, and social and emotional development. Advantages for students and schools related to synergy, scale, and sustainability are discussed.     

成人英语职业化与模块化教学模式构想

成人英语教学是成人高校课程中的一大难点。由于学生个体差异较大，并长期处于传统教学模式下，学生的英语应用能力与职业的要求还有一定的距离。为此，笔者基于自身的教学实践，提出了职业化与模块化英语教学模式的构想，并在论文中阐述了这一构想的出发点，实施要素以及实施效果。
