This paper analyses public e-procurement implementation and emphasizes its main difficulties and impacts in relation to the type of public organizations. The primary impacts and changes in the Portuguese public sector are analyzed within the new legal framework, which adopts mandatory e-procurement for any open, restricted or negotiated procedure. In this sense, two surveys carried out in consecutive years were conducted to assess the implementation difficulties and impact of e-procurement in the Portuguese public sector.The major value of this research is that it presents and discusses, for the first time, evidences about difficulties and impacts on the mandatory adoption of public e-procurement, based on the case of Portugal. The results show that the entities’ administrative level influences the e-procurement implementation, which is influenced by the innovation adoption process. 相似文献

上海立志建设成为国际金融中心,打造这一城市品牌形象是一个系统工程,营销传播工作是重要的组成。本研究从广告效果空间论角度,对上海现有的四部城市形象广告进行了受众认知和态度效果的比较,并引入中外受众所代表的不同涉入度作为调节变量。我们根据结果绘制了四支广告在认知-态度二维图上的位置,并发现不同涉入度对认知效果没有调节作用,而对态度效果上则有调节作用。基于这些发现,我们提出了如何创作有效的国际金融中心城市形象广告的建议。 相似文献

Recent literature has emphasized the emerging role of social media in generating a destination image. Even so, there is still no clear definition of the main actors, typologies and components prevailing in these environments or the possible differences between diverse social platforms. Specific analysis and comparison of the Barcelona TripAdvisor Forum and a traditional Destination Management Organization (DMO) website showed that actors, typologies and components are platform specific and have both similarities and differences with other sources, including DMO websites and other social media platforms. 相似文献

This article provides empirical evidence and contributes to theory building concerning business model fit and dynamics in the area of solutions business. Business models are seen in this context as going beyond considerations such as offerings and internal processes or even relationships, and as including network and market considerations. Indeed the paper highlights the fact that a business model is not firm-focused, nor dyad-focused, but rather network-, and even market-focused, demonstrating that a business model is not static, but dynamic. Manufacturer and customer continuously shift form and content of their respective business models to adapt both to the needs of the counterpart and to market context. A qualitative case study approach is adopted, with subsequent content analysis. The case study relates to the aerospace industry with focus on a complex engineering firm, one of the largest aircraft manufacturers in the world, its customer — a national airline — and their network partners of various kinds. The data were collected through multiple face-to-face interviews with managers in both companies, as a part and parcel of a network of actors that influences and is influenced by the supplier–buyer relationship. Relationships over time between these firms and network partners are described, highlighting the interplay of products and services related to the provision of solutions. Findings highlight the dynamic nature of business models over the relationship lifecycle between supplier and customer in a complex engineering environment, and the need for reciprocal adjustment of models. 相似文献

This study investigated the interaction between proficiency in both mathematics and English on students' performance in the first-year level financial accounting course, The data were gathered on the results of first-year accounting major students at the recently established Hong Kong University of Science and Technology and analysed using regression analysis. The findings showed that a higher degree of proficiency in mathematics was associated with a higher level of performance in the financial accounting course for students who were more competent in English. 相似文献

We consider a consumption and investment problem where the market presents different regimes. An investor taking decisions continuously in time selects a consumption–investment policy to maximize his expected total discounted utility of consumption. The market coefficients and the investor's utility of consumption are dependent on the regime of the financial market, which is modeled by an observable finite-state continuous-time Markov chain. We obtain explicit optimal consumption and investment policies for specific HARA utility functions. We show that the optimal policy depends on the regime. We also make an economic analysis of the solutions, and show that for every investor the optimal proportion to allocate in the risky asset is greater in a "bull market" than in a "bear market." This behavior is not affected by the investor's risk preferences. On the other hand, the optimal consumption to wealth ratio depends not only on the regime, but also on the investor's risk tolerance: high risk-averse investors will consume relatively more in a "bull market" than in a "bear market," and the opposite is true for low risk-averse investors. 相似文献

This study analyses profitability in terms of relationships between various aspects, indicators and cash-crop cultivation preferences. Both financial and pragmatic aspects of profitability were found to be related to cash-crop preferences. Apart from the need to promote a crop with a good farm gate price and to reduce production and marketing costs, promoters need to strengthen the wider system by supporting profitability as well as household consumption requirements. The correlation between indicators of expected profitability improved as more financial and pragmatic aspects were incorporated. Smallholder farmers' rankings of profitability correlated better with cash-crop preferences when the analysis incorporated more aspects of profitability. In addition, the results indicated the institutional support needed to improve the profitability of cash crops. This simple method of identifying smallholder preferences for one cash crop among many is of paramount importance in the design of strategies for improving agricultural market participation. 相似文献

In this article we analyse the determinants of temporary employment through a balanced panel of workers from 1995 to 2000. First, we estimate a panel with 1267 individuals with ages ranging from 16 to 65 years. We obtain that the probability of having a temporary contract increases for people younger than 46 years old. Secondly, we estimate separately the sample of people younger than 46 years old and we obtain that the probability of temporality increases for young people with university level of education. More interestedly, the probability of being in a temporary contract is smaller for young women that for young men in Spain. 相似文献

Business networks (co-operative arrangements between independent business organizations) may be the signature organizational form of the contemporary global economy. Many policy-makers and local leaders advocate business network membership as an alternative development strategy for regional economic vitality. The extant literature on business networks has focused on their association with business success. However, little is known about their impact on other aspects of community life. The purpose of this paper is to elaborate the role of network membership on one non-economic dimension of the business community interface. We examined the relationship between business network membership and business social responsibility to communities, defined as the provision of leadership and support for community betterment projects. Data were gathered from telephone interviews with a random sample of 460 non-metro small business operators in the USA. Independent t-tests and ordinary least squares regression analyses controlling for theoretically important variables were conducted. Findings show that networked businesses provide more leadership and support for their communities than non-networked businesses. However, networked businesses were no more likely than non-networked businesses to use local suppliers of goods and services. 相似文献

Previous studies have highlighted the question of government loan interest as one of great current importance. Government borrowing levels are high, and reducing interest payments would generate savings to meet other spending needs and/or to lower taxation, thus supporting the sustainability of public finances. However, no previous study has presented a method for a local government to calculate its own credit risk and thus be in a position to negotiate lower interest rates on its borrowing. This article defines a financial model that enables local governments to estimate the interest rate payable on a bank loan, based on their credit risk premium, in accordance with the Basel II rules and the findings of our empirical study of large local governments. 相似文献
