中國上市公司強制實施XBRL財務報導格式對於經營績效之影響 –中國國有企業觀點 / The Mandatory Adoption of XBRL and The Firm Performance – Evidence from the State-owned Enterprises in China文經堯 Unknown Date (has links)
為改善資訊揭露環境,並增進上市公司的資訊透明度,上海證券交易所在2004年起對所有上市公司強制實施XBRL財務報導格式,本研究檢驗強制實施XBRL財務報導格式對於公司經營績效之影響,以上海證券交易所上市公司為研究對象,研究期間為2003年至2010年,並考慮中國國有企業的特色,將樣本公司分為國有企業與民營企業,分別檢視強制實施XBRL財務報導格式對其經營績效之影響。基於中國國有企業之組織特性,本研究假設僅有民營企業可獲益於強制實施XBRL財務報導格式,並因此提升經營績效。實證結果顯示,確實僅有民營企業獲得XBRL財務報導的效益,在強制實施XBRL財務報導格式後經營績效提升,但由於組織特性的關係,強制實施XBRL財務報導格式的預期效益並未顯現在國有企業,對中國國有企業來說,資訊透明度與外部監督的提升不足以解決其經營上之代理問題。

Investigating the universality of a semantic web-upper ontology in the context of the African languagesAnderson, Winston Noël 08 1900 (has links)
Ontologies are foundational to, and upper ontologies provide semantic integration across, the Semantic Web. Multilingualism has been shown to be a key challenge to the development of the Semantic Web, and is a particular challenge to the universality requirement of upper ontologies. Universality implies a qualitative mapping from lexical ontologies, like WordNet, to an upper ontology, such as SUMO. Are a given natural language family's core concepts currently included
in an existing, accepted upper ontology? Does SUMO preserve an ontological non-bias with respect to the multilingual challenge, particularly in the context of the African languages? The approach to developing WordNets mapped to shared core concepts in the non-Indo-European language families has highlighted these challenges and this is examined in a unique new context: the Southern African
languages. This is achieved through a new mapping from African language core concepts to SUMO. It is shown that SUMO has no signi ficant natural language ontology bias. / Computing / M. Sc. (Computer Science)

Previous issue date: 2005 / Resumo: Este trabalho apresenta uma infra-estrutura para auxílio ao desenvolvimento de software baseado em componentes para dispositivos móveis com baixo poder de processamento e armazenamento. Esta infra-estrutura baseia-se em um modelo de componentes neutro em termos de tecnologia e especificado inteiramente em UML (Unified Modeling Language). A plataforma utiliza Web Services para comunicação síncrona entre os componentes. Um Serviço de Notificação baseado em documentos XML (Extensible Markup Language) foi desenvolvido para suporte a notificação assíncrona entre componentes. Um exemplo de aplicação na área de gerência de redes ilustra as funcionalidades da infra-estrutura / Abstract: This work presents an infrastructure for supporting component-based software development for mobile devices with limited resources regarding processing power and storage. This infrastructure is based on a neutral component model in terms of technology and specified entirely in UML (Unified Modeling Language). The platform employs Web Services for synchronous communication between components. A Notification Service based on XML (Extensible Markup Language) documents was developed in order to support asynchronous communication among the components. An example of application in the field of network management illustrates the functionalities of the infrastructure / Mestrado / Engenharia de Computação / Mestre em Engenharia Elétrica

Publikace dat ze sítě meteostanic ve formátu DATEX II / Implementation of Datex II standard for road transport weather stationsPartika, Marek January 2016 (has links)
Master’s thesis deals with implementation of a European standard DATEX II. This standard specifies the data format for information transmission in road transport. The road traffic is flowing streams of current information. For the work was selected network of meteorological stations, which will publish the measured data, ie weather conditions of road transport. Measured data will be available to consumers in the format DATEX II. Implementation will be operational in its entirety meteorological station from design to the actual web service that will produce data information for consumers.
