This conceptual article discusses strategies of corporations in the information and communication technologies (ICT) sector and their role in the conflict over access to knowledge in the digital environment. Its main hypothesis is that ICT corporations are very capable actors when it comes to bridging digital divides in both developed and developing countries??maybe even the most capable actors. Therefore, it is argued that ICT corporations could use their capabilities to help citizens gain sustainable access to knowledge in order to enable them to lead self-sufficient lives. In a nutshell, capabilities are presented as both the input (capabilities of ICT corporations) as well as the output (capability building for empowering citizens) of corporate strategy-making focusing on fair ICT. Corporate citizenship is put forth as the theoretical concept bridging corporate strategies and access to knowledge: If ICT corporations act in accordance with their self-understanding of being ??good corporate citizens??, they could be crucial partners in lessening digital divides and helping citizens gain access to knowledge. From the perspective of ??integrative economic ethics?? (Ulrich 2008), it is argued that ICT corporations have good reason to actively empower citizens in both developed and developing countries by pursuing ??inclusive?? strategies in many fields, such as open-source software development. That way, ICT corporations could enable, support and provide citizens with capabilities enabling them to help themselves. In order to make inclusive business models work, the rules and regulations companies find themselves in today must enable them to act responsibly without getting penalized by more ruthless competitors. This article explores several cases from the ICT field to illustrate the interplay between a responsible business model and the rules and regulations of the industry. From a capabilities perspective, the most desirable mix of corporate strategies and industry regulation is one that results in the highest level of generativity (Zittrain 2008). Thus, ICT should not be closed systems only driven by the company behind them. Instead, they need to be open for the highest possible level of third-party innovation.  相似文献

Separation and sorting of biological entities (viruses, bacteria, and cells) is a critical step in any microfluidic lab-on-a-chip device. Acoustofluidics platforms have demonstrated their ability to use physical characteristics of cells to perform label-free separation. Bandpass-type sorting methods of medium-sized entities from a mixture have been presented using acoustic techniques; however, they require multiple transducers, lack support for various target populations, can be sensitive to flow variations, or have not been verified for continuous flow sorting of biological cells. To our knowledge, this paper presents the first acoustic bandpass method that overcomes all these limitations and presents an inherently reconfigurable technique with a single transducer pair for stable continuous flow sorting of blood cells. The sorting method is first demonstrated for polystyrene particles of sizes 6, 10, and 14.5 μm in diameter with measured purity and efficiency coefficients above 75 ± 6% and 85 ± 9%, respectively. The sorting strategy was further validated in the separation of red blood cells from white blood cells and 1 μm polystyrene particles with 78 ± 8% efficiency and 74 ± 6% purity, respectively, at a flow rate of at least 1 μl/min, enabling to process finger prick blood samples within minutes.  相似文献

The unification of the two German states in October 1990 had a significant impact on educational politics. The combination of two educational and university systems that were based on clearly divergent political and social foundations lay ahead. The thesis is discussed here that the unification of FRG and GDR could not lead to the renewal of universities in Germany but only to an adaptation of eastern society to western society. But with the foundation of a Faculty of Educational Sciences at the Technical University of Dresden (Land Saxony) successful attempts to renewals at an intermediate level are also presented. The author describes the production and realization of a project he helped to develop and at the same time addresses the emerging problems the new faculty triggered.  相似文献

The Czech Republic, England, France, Germany and Sweden differ culturally and economically, but they commonly exhibit general trends of decentralisation in the control of educational processes and outcomes. The present contribution looks at these five European countries as the venue for case studies in educational restructuring as well as evaluation, assessment and reporting. It shows that such trends have been most radical in the Czech Republic and Sweden, while England has centralised curriculum policy and France has devolved some decision-making to bodies at lower levels, but as representatives of the central state.  相似文献

The way students and teachers evaluate mathematics achievement differs in certain respects. To which causal performance is ascribed determines the teacher's strategy to interact with the student on the one hand and influences the student's willingness to invest additional effort on the other. Certain possible causal factors for success and failure in mathematics and their relation to teacher-student-interaction are discussed in the present article. A rather general cognitive scheme, the teachers reference norm, explains differences between the teacher's perception and assessment of student characteristics and subsequent teaching interventions.  相似文献

Knowledge management (KM) has matured to the point that many organisations either believe they have such practices in place or at least understand they are relevant to the knowledge work commonly undertaken in many industries. What is lacking from the literature, however, is a solid foundation for the philosophies underpinning KM and particularly for how tacit knowledge informs the KM space. Research over decades shows tacit knowledge underpins all other forms of knowledge, enabling the interpretation and judicious application of knowledge, leading (at its highest levels) to the concept of wisdom. As an academic discipline, artificial intelligence (AI) was established before KM, has been grounded in the computing discipline for many decades, and is applied broadly in many domains. This paper explores how AI can inform the KM debate. Rather than simply provide examples of AI success stories as applied to KM in practice, it explores the theoretical and practical limitations of AI and KM in unison, providing at the same time a strong epistemological understanding of both disciplines as a means of furthering the knowledge debate, with particular emphasis on the role of tacit knowledge within this jurisdiction.  相似文献

The purpose of this study was to examine perceptions of local residents prior to the public referendum for the 2024 Hamburg Olympic bid and to assess their level of support for the bid. The representative survey conducted amongst Hamburg residents reveals a high level of support but also a strong perception of negative legacies. A comparison between the perceived positive and negative legacies shows that the negative legacies outweigh the positive legacies. When examining factors that influence support, statistical analysis reveals the perception of positive legacies as the strongest predictor of support. The survey also indicates that residents attach great importance to the costs of the Games and feel no personal benefit from hosting them. The findings suggest that Games organizers and authorities should mostly rely on positive legacies while negative legacies ought to be mitigated.  相似文献
