Purpose The purpose of this paper is to aid the convergence of design and management as a strategic lever and innovative tool to improve corporate reputation in higher education institutions (HEIs), particularly in the Polytechnic Institute of Bragança, Portugal (IPB). Design/methodology/approach SWOT analysis is used to identify strengths and weaknesses in the context of an organization’s internal competencies (identity) and opportunities and threats in an analysis of the organization’s external competitive context (image). Quantitative analysis was used based on questionnaires conducted with IPB community to analyse if differences exist between identity (staff) and image (students) and where there are design structures (website, visual identity, advertising and environment. Corporate character scale developed by Davies et al. (2003, 2004) was used. Findings With the SWOT analysis, it is possible to outline IPB performance strategies that meet a positive reputation. A positive corporate reputation was found in IPB with the study of corporate character scale. It has been realized where there are differences from the point of view of identity and image, and thus, it is possible to indicate ideas of improvement to increase the competitiveness of HEIs. Research limitations/implications The study is restricted to five schools of IPB. It would also be pertinent to broaden the scope of the stakeholders, encompassing the external community of the IPB that is extending the study to the external public, such as parents, companies, suppliers and secondary students. Practical implications HEI competitiveness implies student recruitment and public policies. A positive reputation implies a positive brand image. Design competencies of the public higher education sector can go much further acting at the strategic level, establishing its directives of action in the markets where it operates to reflect its corporate reputation in a positive way in the mind of the consumer. Intangible assets such as identity, image and corporate reputation, appear as very valuable elements, presenting an increasing importance in the management of universities that entered a market context where sustainability requires the adoption of more entrepreneurial management guidelines. Originality value The paper is useful for the professionals and academics in perceiving the importance of use management and strategical tools to identify HEI communication and reputation difficulties for a thorough design thinking that delineates solutions that leverage the competitiveness of service organizations such as HEIs.
This paper evaluates scalable distributed crawling by means of the geographical partition of the Web. The approach is based on the existence of multiple distributed crawlers each one responsible for the pages belonging to one or more previously identified geographical zones. The work considers a distributed crawler where the assignment of pages to visit is based on page content geographical scope. For the initial assignment of a page to a partition we use a simple heuristic that marks a page within the same scope of the hosting web server geographical location. During download, if the analyze of a page contents recommends a different geographical scope, the page is forwarded to the well-located web server.A sample of the Portuguese Web pages, extracted during the year 2005, was used to evaluate: a) page download communication times and the b) overhead of pages exchange among servers. Evaluation results permit to compare our approach to conventional hash partitioning strategies.
Abstract. Clusters that combine heterogeneous compute device architectures, coupled with novel programming models, have created a true alternative to traditional (homogeneous) cluster computing, allowing to leverage the performance of parallel applications. In this paper we introduce clOpenCL, a platform that supports the simple deployment and efficient running of OpenCL-based parallel applications that may span several cluster nodes, expanding the original single-node OpenCL model. clOpenCL is deployed through user level services, thus allowing OpenCL applications from different users to share the same cluster nodes and their compute devices. Data exchanges between distributed clOpenCL components rely on Open-MX, a high-performance communication library. We also present extensive experimental data and key conditions that must be addressed when exploiting clOpenCL with real applications.
This paper presents a multi-objective approach to Web space partitioning, aimed to improve distributed crawling efficiency. The investigation is supported by the construction of two different weighted graphs. The first is used to model the topological communication infrastructure between crawlers and Web servers and the second is used to represent the amount of link connections between servers' pages. The values of the graph edges represent, respectively, computed RTTs and pages links between nodes. The two graphs are further combined, using a multi-objective partitioning algorithm, to support Web space partitioning and load allocation for an adaptable number of geographical distributed crawlers. Partitioning strategies were evaluated by varying the number of partitions (crawlers) to obtain merit figures for: i) download time, ii) exchange time and iii) relocation time. Evaluation has showed that our partitioning schemes outperform traditional hostname hash based counterparts in all evaluated metric, achieving on average 18% reduction for download time, 78% reduction for exchange time and 46% reduction for relocation time.
