英语课堂教学中对功能语法语篇分析模式的运用

本文主要依据韩礼德的功能语法语篇分析理论,结合笔者自身的教学经验,对英语课堂教学进行了反思,进而从语篇的宏观结构、语域分析、主位结构及衔接与连贯分析角度探讨了在英语课堂教学中对功能语法语篇分析模式的运用.     

母公司在集团网络中的功能定位与职能设置

首先对母子公司进行了描述与界定,对系统内部资源进行了分类对比分析,然后讨论了母公司在网络系统中的整体功能定位,得出母公司是母子公司网络系统中系统公共资源的创造与管理中心,从而重点引出母公司对网络系统公共资源的管理策略分析与网络系统资源差异对总部职能设置的影响分析,由此得出母子公司网络系统的总部职能结构设置思路与原则。     

INTENSITY-BASED VALUATION OF RESIDENTIAL MORTGAGES: AN ANALYTICALLY TRACTABLE MODEL

This paper presents an analytically tractable valuation model for residential mortgages. The random mortgage prepayment time is assumed to have an intensity process of the form h _t = h ₀( t ) +γ ( k − r _t )⁺ , where h ₀( t ) is a deterministic function of time, r _t is the short rate, and γ and k are scalar parameters. The first term models exogenous prepayment independent of interest rates (e.g., a multiple of the PSA prepayment function). The second term models refinancing due to declining interest rates and is proportional to the positive part of the distance between a constant threshold level and the current short rate. When the short rate follows a CIR diffusion, we are able to solve the model analytically and find explicit expressions for the present value of the mortgage contract, its principal-only and interest-only parts, as well as their deltas. Mortgage rates at origination are found by solving a non-linear equation. Our solution method is based on explicitly constructing an eigenfunction expansion of the pricing semigroup, a Feynman-Kac semigroup of the CIR diffusion killed at an additive functional that is a linear combination of the integral of the CIR process and an area below a constant threshold and above the process sample path (the so-called area functional). A sensitivity analysis of the term structure of mortgage rates and calibration of the model to market data are presented.

Understanding the exploration–exploitation dilemma: An fMRI study of attention control and decision‐making performance

This paper studies the cognitive processes that enable decision makers to switch between exploitation and exploration. We use functional magnetic resonance imaging (fMRI) in a sample of expert decision makers to make two main contributions. First, we identify and contrast the specific brain regions and cognitive processes associated with exploitation and exploration decisions. Exploitation activates regions associated with reward seeking, which track and evaluate the value of current choices, while exploration relies on regions associated with attentional control, tracking the value of alternative choices. Second, we propose and test the idea that stronger activation of the brain circuits related to attentional control allows individuals to achieve better decision‐making performance as a result. We discuss the implications of these results for strategic management research and practice. Copyright © 2013 John Wiley & Sons, Ltd     

高速公路服务区物流结点的功能定位

我国高速公路事业的快速发展,促进了高速公路服务区功能的转变,这种功能的转变与我国经济社会的发展是分不开的。对服务区的停车、休息、如厕等基本服务功能的开发已不能满足高速公路经营企业追求经济效益的要求,因此,对高速公路服务区做出科学合理的功能定位十分必要。     

上海城乡经济多样化测度方法及其演变特征

以上海市为例,从作物多样化、产业发展多样化、土地利用结构多样化、城市经济功能多样化等视角,提出了相应的定量测度方法并展开实证分析。研究结果表明:11950年以来,尽管大多数区县的作物多样化程度趋于下降态势,但上海郊区的作物多样化程度依然较高;近郊区的作物多样化程度的下降幅度大于远郊区,且两者的作物多样化程度在1990年前后发生了明显改变。2改革开放以来,上海农业发展日益趋于多样化;上海工业则经历了"两升两降"的结构调整和优化过程,优势工业行业的集中化和专业化与其它工业行业的分散化和多样化交替演进;上海服务业的多样化程度总体上呈现在波动中上升的态势。31996年以来,上海土地利用结构多样化指数基本呈现上升趋势,且土地利用结构的多样化程度总体较高。41980年以来,上海城市经济功能多样化态势日益明显,产业结构升级与就业结构多样化互动发展。     

Understanding customers’ healthy food choices at casual dining restaurants: Using the Value–Attitude–Behavior model

This study examined how individual health values influence interest in healthy foods, positive outcome expectations, hedonic expectations, and behavior intentions. A total of 1188 valid questionnaires were collected from customers who had consumed healthy menu items at casual dining restaurants. The results indicated that health value was the key element that inspired customer interest in healthy eating and aroused hedonic and positive outcome expectations, which in turn enhanced intentions to purchase healthy food items. Restaurant managers are advised to establish creative marketing strategies to motivate customer interest in healthy menu items and emphasize benefits of their healthy food items. Future studies can extend the scope of research by examining differences in geographical areas or demographic profiles.
