引进技术的法制研究——解读《国家中长期科学和技术发展规划纲要(2006-2020年)》

在竞争日益激烈的今天,引进技术很重要,引进技术的消化、吸收和再创新更是重中之重。引进技术消化、吸收和再创新需要国家政策的宏观引导,而政策的实施主要依靠法律的保障,如果没有法律具体规定,权责不明确,责任不落实,引进技术消化、吸收和再创新也只能是空谈。通过分析我国技术引进的发展和现状,对《规划纲要》中引进技术的法制问题做一简要研究。     

Modelling bank customer behaviour using feature engineering and classification techniques

This study investigates customer behaviour and activity in the banking sector and uses various feature transformation techniques to convert the behavioural data into different data structures. Feature selection is then performed to generate feature subsets from the transformed datasets. Several classification methods used in the literature are applied to the original and transformed feature subsets. The proposed combined knowledge mining model enable us to conduct a benchmark study on the prediction of bank customer behaviour. A real bank customer dataset, drawn from 24,000 active and inactive customers, is used for an experimental analysis, which sheds new light on the role of feature engineering in bank customer classification. This paper’s detailed systematic analysis of the modelling of bank customer behaviour can help banking institutions take the right steps to increase their customers’ activity.     

New plant engineering techniques,R&D investment and international trade

New plant engineering techniques (NPETs) may significantly improve both production and quality of foods. Some consumers and regulators around the world might be reluctant to accept such products and the global market penetration of these products may remain low. We develop a parsimonious economic model for R&D investment in food innovations to identify conditions under which NPET technology emerges in the context of international trade. The framework integrates consumers' willingness to pay (WTP) for the new food, the uncertainty of R&D processes, the associated regulatory cost of approval, and the competition between domestic and foreign products. With generic applicability, the model enables the quantitative analysis of new foods that could be introduced in markets and then traded across borders. We apply the framework to a hypothetical case of apples improved with NPETs. Simulation results suggest that import bans and high values of sunk cost can reduce R&D investment in NPETs to suboptimal levels.     

Enhancing Students' Enabling Competencies: Student Perspectives and Recommendations for Educators*

Employers continue to express concern that accounting graduates lack the necessary competencies when they enter the workplace. These concerns have been addressed in part by periodic revisions to Chartered Professional Accountants of Canada's (CPA Canada) CPA Competency Map, which is used to define competencies for entry into the profession. The CPA Competency Map has recently been revised to include a new set of enabling competencies (often called generic or soft skills). However, the accounting literature highlights a concern that time and resources spent on the expanding set of enabling competencies could take valuable resources away from teaching technical accounting skills. In addition, the education literature indicates that student motivation plays a key role in learning. If students are motivated to learn enabling competencies, then educational efforts could be more efficient and effective. Conversely, a lack of student motivation could reduce student engagement and learning. To address these concerns, we investigated the student's perspective on the importance of enabling competencies as well as on how and where enabling competencies should be learned. We surveyed 380 students enrolled in the CPA Canada Professional Education Program (PEP). We investigated the three new enabling competencies that are most distinct from the previous set of competencies and that may be the most difficult for accounting educators to teach: adaptability and resilience; creativity and innovation; and active listening. We asked students about the importance of these new enabling competencies for their future careers and whether the competencies should be taught in PEP or in the workplace. Our results indicate that students believe that the new enabling competencies are important and should be learned in both the classroom and the workplace. Moreover, student responses to open-ended questions provide educators with suggestions on how to incorporate enabling competencies into the classroom by blending activities that could simultaneously enhance enabling competencies with technical competencies.     

企业领导者道本心智模式构念开发——基于扎根理论编码技术的研究

运用扎根理论编码技术，以《道德经》为研究文本，开发了企业领导者道本心智模式的构念体系，并分析了各维度之间的逻辑关系。研究发现：道本心智模式主要由哲学思维、道本行为、至善信念和合一目标四个维度组成。通过与现有心智模式理论进行比较分析，发现道本心智模式在研究视角、关注重点和追求目标等方面有所创新，并为企业管理实践中领导者心智的修炼提供了方向。     

Cross-temporal forecast reconciliation: Optimal combination method and heuristic alternatives

Forecast reconciliation is a post-forecasting process aimed to improve the quality of the base forecasts for a system of hierarchical/grouped time series. Cross-sectional and temporal hierarchies have been considered in the literature, but generally, these two features have not been fully considered together. The paper presents two new results by adopting a notation that simultaneously deals with both forecast reconciliation dimensions. (i) The closed-form expression of the optimal (in the least squares sense) point forecasts fulfilling both contemporaneous and temporal constraints. (ii) An iterative procedure that produces cross-temporally reconciled forecasts by alternating forecast reconciliation along one single dimension (either cross-sectional or temporal) at each iteration step. The feasibility of the proposed procedures, along with first evaluations of their performance as compared to the most performing ‘single dimension’ (either cross-sectional or temporal) forecast reconciliation procedures, is studied through a forecasting experiment on the 95 quarterly time series of the Australian Gross Domestic Product from Income and Expenditure sides. For this dataset, the new procedures, in addition to providing fully coherent forecasts in both cross-sectional and temporal dimensions, improve the forecast accuracy of the state-of-the-art point forecast reconciliation techniques.     

Practice Makes Better: Using Immersive Cases to Improve Student Performance on Day 1 of the Common Final Examination*

In the context of an accredited CPA program, we investigate whether an immersive case delivered over several weeks in a team-based environment in the Performance Management elective module improves student performance on Day 1 examinations and whether all students benefit equally from the immersive case. Results show that using an immersive case prior to Capstone 1 significantly improves student performance on practice Day 1 examinations and Day 1 of the Common Final Examination (CFE). Although high-ability students and non-English-as-a-second-language (ESL) students with co-op experience perform better regardless of whether an immersive case is used, ESL students benefit from using an immersive case when evaluating performance on Day 1 of the CFE. In addition, spending six to eight weeks preparing extensively for the CFE after graduate classes end in July seems to contribute to closing performance gaps between students. This study benefits the education process by identifying a tool that educators can use to improve performance on the CFE. It provides insights that may prove useful to CPA Canada and accredited post-secondary institutions as they revamp their programs to align with Competency Map 2.0.
