Financial information management for university departments,using open-source software     

《International Journal of Information Management》2014,34(2):191-199

This paper presents a model to analyse the different outcomes generated by the application of Task-Technology Fit (TTF) theory to economic and financial information management in university departments. This model extends that proposed by Goodhue (1995), in two ways: (i) a key role is played by the manager in designing the technology and in performing the task in question. Both of these aspects can be modified, depending on the evaluation made of a series of characteristics (or dimensions) inherent to the model. (ii) The free dissemination of the source code of the application not only allows the transfer of knowledge, but also creates virtual communities which, through collaborative work and the exchange of experiences, can achieve a better fit of the technology to the task at hand. This model has been introduced in several departments at the University of Granada (Spain), and evaluated in terms of the results obtained at both individual and group levels. This evaluation was conducted by means of in-depth interviews with departmental managers.  相似文献   

第二版《汉语大字典》引《古俗字略》疑误举例     

熊加全 《保定学院学报》2014,(6)

《古俗字略》的主要工作是认同异体字,指明其间的“古”、“俗”、“通”关系。其中尽管有可取之处,但也存在不少疏漏。第二版《汉语大字典》对这些疏漏往往未加辨析就加以援引,由此造成了部分失误。举例分析并补正这些疑误,使其有益于《汉语大字典》的再次修订。  相似文献

二语习得的关键期假说及对外语教学的启示     

曹燕黎 《大学.研究与评价》2009,(9):30-33

本文回顾了20世纪60年代以来对二语习得关键期的研究,从赞成派和反对派两方面为此理论提供依据,并指出第三种可能:二语习得可能存在多重关键期,即存在多个关键期在不同时期影响语言习得的不同方面。指出成人外语教学应实施不同的教学策略,利用成人外语学习的优势采用相应的教学方法,以达到最佳的学习效果。  相似文献

Dynamic Stackelberg games under open-loop complete information     

Pu-yan Nie 《Journal of The Franklin Institute》2005,342(7):737-748

Stackelberg games, which play extremely important roles in such fields as economics, management, politics and behavioral sciences, can be modelled as a bilevel optimization problem. There exist extensive literatures about static bilevel optimization problems. However, the studies on dynamic bilevel optimization problems are rather scarce in spite of the importance in explaining and predicting some phenomena rationally. In this paper, discrete time dynamic Stackelberg games with open loop complete state are revisited. An example, which comes from law field, is presented as an open-loop Stackelberg game to illuminate the rangy application of game theory. A property based on Bellman's equation is proposed without any restriction about inner point solution for open-loop Stackelberg games in this work. Moreover, we point out that open-loop Stackelberg games perform no better than both feedback and closed-loop dynamic Stackelberg games with complete information, which seems quite valuable to explain some social and economic phenomena.  相似文献   

含DMPP硫硝铵不同基追肥比例对小青菜硝酸盐累积及品质的影响   总被引：7，自引：0，他引：7  

许超  吴良欢  巨晓棠  张福锁 《科技通报》2004,20(5):464-467

采用土培试验对含硝化抑制剂DMPP(3，4-二甲基吡唑磷酸盐)硫硝铵(ASN)氮肥(简称ASN DMPP)不同基追肥比例对小青菜硝酸盐累积及营养品质的影响进行了探讨．结果表明，等氮量(每千克土用0．5g氮)施用条件下基肥75％、追肥25％的基追肥比例不仅可提高蔬菜产量、降低硝酸盐含量，还可提高Vc、氨基酸、Zn、N、K含量，改善了蔬菜品质。  相似文献

A tale of two literatures: Transaction costs and property rights in innovation outsourcing     

Nishaal Gooroochurn 《Research Policy》2007,36(10):1483-1495

This paper investigates the relative importance of property rights and transactions cost factors in driving the decision of firms to outsource innovation. Using data for over 8000 firms from the UK Community Innovation Survey, we find that property right factors dominate over transaction cost factors. Transaction cost variables are more important for process innovation, while property rights variables are more significant for firms involved in product innovation. In addition, we find that firms involved in process innovation have a higher probability of outsourcing innovation than firms involved in product innovation.  相似文献
