互文性理论视角下大学英语写作教学方法探析

互文性理论认为每个语篇都是对其他语篇的吸收和转化，语篇不是孤立的，总是存在于语篇网络中。互文性是西方结构主义和后现代主义文化思潮中产生的文本理论，但是目前对于互文性理论的研究多以文学批评理论的研究和文学作品研究为主，作为教学策略应用于英语教学的研究则为数不多。本文通过探讨互文性理论指导下大学英语写作教学的实践意义及目前大学英语写作教学存在的问题，提出了笔者在教学实践中所积累的几点写作教学法，以期为大学英语写作教学模式提供新的思路。     

How to move away from the silos of business management education?

Business management education is criticized for being too theoretical and fractional. Despite the numerous efforts to build integrated and experiential business curricula, learning is still organized in disciplinary silos. The curriculum integration efforts are carried out in separate sections of the curriculum rather than the core. There are theoretical, holistic models, but a lack of concrete examples of holistic business curriculum implementations. The authors bring the separate sections together by developing a holistic core curriculum model with three perspectives: a structure to bring intellectual coherence, people organized in learning communities, and an enterprise resource planning–supported learning environment to bring the practical training ground. The authors present a concrete implementation in a case study with first-year undergraduate business students and present their lessons learned.

Identifying cycling-inducing neighborhoods: A latent class approach

Understanding how spatial attributes of cities and neighborhoods induce cycling is relevant for urban planning and policy making. In this work, ordered logit and latent class models are specified and estimated to analyze how the built environment affects bicycle-commuting frequency. Data come from a survey to 1,487 people in the city of Santiago, Chile, including sociodemographic information, travel behavior patterns and place of residence and work. Using geographic information systems tools, the built environment was characterized with variables calculated for a 500-m-radius buffer around the residential and work locations of each individual. Two models are estimated, first an ordered logit model confirms that built environment variables effect on cycling is similar to what has been reported in the literature, with some new findings such as an increase in cycling when public transport accessibility is low and the role of built environment attributes at the destination. Second, a latent class ordered logit is used to identify two classes of neighborhood in term of their cycling patterns, as a function of their density, presence of cycling infrastructure and distance to the main activity center of the city. This result allows to map the class membership probabilities, potentially helping to identify neighborhoods that encourage cycling and providing relevant information for policy making and infrastructure decisions.     

中国沿海地区经济结构变动对海洋环境的影响

中国沿海经济结构的研究对海洋环境的发展意义重大,然而二者之间的定量关系及内在机理尚不完全清楚。以2007-2016年为研究时段,我国沿海11省(区、市)为研究区域,借助固定效应以及门槛模型,测度经济结构变动与海洋环境之间的关系。结果表明:①在经济结构中产业结构(-0.099)对海洋的弹性系数最大,其次是经济增速(-0.058),投资对象为正向影响,但不显著;非经济结构中,技术进步(0.052)的弹性系数最大,其中环境规制(-0.045)、人口规模(-0.045)抑制海洋环境的改善。②区域对比北部、东部海洋经济圈产业结构对海洋环境起抑制作用,另外,东部海洋经济圈环境规制、人口规模与海洋环境水平呈明显的负相关性;南部海洋经济圈相对于其他两个区域,结果不显著。③将产业结构、技术进步作为门槛变量,在各自的作用下分别存在双重门槛和单一门槛。产业结构门槛值为0.533、0.462,仅河北,福建未跨越第二门槛;科研能力门槛值为40,仅河北、福建、海南未跨过门槛值。因此,应适度调整产业结构,注重经济增长的质量,合理控制城镇人口的流动,积极鼓励科研创新,实现经济与海洋环境协调发展。     

Economic policy uncertainty and analysts’ forecast characteristics

We examine the influence of economic policy uncertainty (EPU) on the characteristics of analysts’ earnings forecasts over a thirty-year period, spanning a wide variety of political and economic conditions. Motivated by both theory and empirical evidence that suggest a decline in the quality of the information environment for firms as EPU increases, we establish that analysts’ forecast errors increase with EPU, as does the degree of forecast dispersion. Increased error and dispersion persist after controlling for several competing sources of economy-wide uncertainty. Cross sectional analysis exploring heterogeneity in forecast quality across both analyst and firm characteristics establishes that forecast error and dispersion increase with EPU across a broad spectrum of firms and levels of analyst expertise. We control for analysts’ experience overall and the years spent covering a particular industry and firm. Five alternative methods for classifying firms as policy sensitive versus policy neutral provide consistent evidence that analyst forecast errors and dispersion increase with EPU, even for firms not deemed to be particularly sensitive to policy.     

The intellectual structure of the journal Business Strategy and the Environment: A 25‐year author cocitation analysis

This article presents the intellectual structure and 25‐year author cocitation analysis of the journal Business Strategy and the Environment. The findings show that Business Strategy and the Environment is an emerging, well‐established journal in its field. The journal needs a core set of authors who are actively engaged in the production and certification of knowledge; further, it consists of a number of loosely linked research team contributors, each with its own areas of interest. The existence of these research teams is a sign of strength that characterizes the journal as it strives to foster a community of unified scholars whose published works advance our understanding of business strategic decisions and behavior with regard to the natural environment. This study is useful for contributors, readers, and editorial board members who form the journal's community of knowledge creation and certification.     

Effects of employees’ opportunities to influence in-store music on sales: Evidence from a field experiment

The effects of in-store music on consumer behavior have attracted much attention in the marketing literature, but surprisingly few studies have investigated in-store music in relation to employees. By conducting a field experiment in eight Filippa K fashion stores in Stockholm, Sweden, we investigate whether it is beneficial for store owners to give employees more opportunities to influence the in-store music. We randomly assigned the stores into a treatment group and a control group, with the employees in the treatment stores having the opportunity to influence the in-store music through an app developed by Soundtrack Your Brand (SYB). The experiment lasted 56 weeks and sales data were also gathered 22 weeks before the experiment, resulting in a total of 4626 observations. Our results show that sales decreased by 6% when the employees had the opportunity to influence the music played in the store, and the effect is driven by a reduction in sales of women's clothing. Interviews with the employees revealed that they had diverse music preferences, frequently changed songs, and preferred to play high-intensity songs. Employees thus seem to make choices regarding the in-store music that reduce sales, implying that store owners might want to limit their opportunities to influence the background music.     

Voluntary pricing mechanisms for green product purchase: altruistic versus self-enhancing consideration

Voluntary pricing mechanisms, such as Pay-What-You-Want (PWYW), could be a better pricing strategy to substitute for cash discount promotions. They can effectively promote the sales of conventional goods and services, while being influenced by socio-psychological variables. However, there is no clarity on the relative assessment of the impact of pricing frames, such as PWYW and Mark-Off-Your-Own-Price (MOYOP), on the consumers’ purchase of green products, where the purchase consideration might vary as the environment protection (altruistic) consideration versus the self-interest (self-enhancing) consideration. Further, there remains ambiguity on when and why such pricing mechanisms will work. This study, through an experiment, examines the buyers’ varied responses for the PWYW price frame versus the MOYOP price frame versus the fixed price frame under the environment protection (altruistic) consideration versus the self-interest (self-enhancing) consideration. It shows that although buyers do not show any difference in the mean voluntary payment between PWYW versus MOYOP frames as such; they prefer PWYW price frame under the environment protection (altruistic) consideration and MOYOP price frame under the self-interest (self-enhancing) consideration. The results show that the perception of price fairness mediates the relationship between pricing mechanism and willingness to buy (WTB). Furthermore, this study finds that price consciousness impacts the indirect effect of pricing mechanisms on WTB via perceived price fairness. The present study is the first to examine and analyze different considerations when the buyers’ preference varied for the PWYW versus MOYOP pricing frames. This study has suggested the underlying role of the perception of price fairness and price consciousness in the participative pricing mechanism on purchase.
