A study on two-layered model (Casson-Newtonian) for blood flow through an arterial stenosis: Axially variable slip velocity at the wall

The present paper sheds some light on a mathematical model for blood flow through stenosed arteries with axially variable peripheral layer thickness and variable slip at the wall. The model consists of a core region of suspension of all the erythrocytes assumed to be a Casson fluid and a peripheral layer of plasma as a Newtonian fluid. For such models, in literature, the peripheral layer thickness and slip velocity are assumed a priori based on experimental observations. In the present analysis, new analytic expressions for the thickness of the peripheral layer, slip velocity and core viscosity have been obtained in terms of measurable quantities (flow rate (Q), centerline velocity (U), pressure gradient (−dp/dz), plasma viscosity (μ_p) and yield stress (θ)). Using the experimental values of Q, U, (−dp/dz), μ_p and θ, the values of the peripheral layer thickness, core viscosity, and slip velocity at the wall have been computed. The theoretically obtained peripheral layer thickness has been compared with its experimental value. It is found that the agreement between the two is very good (error<1.4%). Further, a comparison between theoretical and experimental values of core viscosity is made and it is observed that the error between the two becomes 3.7465% in the case of two-layered model (Casson-Newtonian) for tube diameter 40 μm. The analysis developed here could be used to determine the more accurate values of the apparent viscosity of blood, agreeability, rigidity and deformability of red cells. This information of blood could be useful in the development of new diagnosis tools for many diseases.     

Making memories available: a framework for preserving rural heritage through community knowledge management (cKM)

While most of the research in Knowledge Management (KM) has focused on business communities, there is a breadth of potential applications of KM theory and practice to wider society. This paper explores the potential of KM for rural communities, specifically for those that want to preserve their social history and collective memories (what we call heritage) to enrich the lives of others. In KM terms, this is a task of accumulating and recording knowledge (using KM techniques such as story-telling and communities of practice) to enable its retention for future use (by interested people perhaps through KM systems). We report a case study of Cardrona, a valley of approximately 120 people in New Zealand's South Island. Realising that time would erode knowledge of their community a small, motivated group of residents initiated a KM programme to create a legacy for a wider community including younger generations, tourists and scholars. This paper applies KM principles to rural communities that want to harness their collective knowledge for wider societal gain, and develops a community-based framework to inform such initiatives. As a result, we call for a wider conceptualisation of KM to include motives for managing knowledge beyond business performance to accommodate community (cKM).     

Applying a multi-dimensional hedonic concept of intrinsic motivation on social tagging tools: A theoretical model and empirical validation

Participation in and adding content to social tagging tools is important for these tools to achieve their purpose of classifying and organizing information. Users of social tagging tools are driven to participate and add tags by extrinsic and intrinsic motivation. Extrinsic motivation is dominating research as a main predictor of why users use information systems. Social tagging tools, as a subset of social media tools, are distinguished by their unique social aspect that makes intrinsic motivation a potential driver for users to add tags to content. Intrinsic motivation, when applied to social tagging tools, could entail many shades that represent different users’ motives for using such tools. In this paper, we add a rich concept of intrinsic motivation to include hedonism as a main predictor of users’ behavior on social tagging tools. We empirically validate a previously proposed theoretical model of three dimensional concepts of hedonism with three components describing individuals’ hedonic state when interacting with social tagging tools: explorability, curiosity, and enjoyment. After a robust and thorough data analysis using structured equation modeling, the results confirm our theoretical model and suggest using a richer concept of enjoyment to reflect a hedonic dimension when investigating intrinsic motivation with interactive social media tools. Our validated model could be the spark of new factors that have the potential to influence user acceptance of information systems in general and in social media tools. This research contributes to the development of attitude-behavior theories that could explain users’ acceptance of dynamic web

基于PPP(公私合作)视角的科技资源共享服务机制研究——以重庆为例的分析

研究发现,现有科技资源共享服务管理出现问题的根源在于未正确处理好科技资源"公共品"和"私人品"的双重价值属性矛盾。基于此,以重庆为例,充分考虑科技基础资源双重价值属性,结合国家鼓励社会资本参与科研基础设施社会化服务的政策要求,从PPP(公私合作)的视角,构建科技资源共享服务管理模式,建立保证该模式成功运行的成本收益分配机制、协调管理机制、资源整合机制、回报机制、激励与约束机制和相应制度。     

基于业务流程再造理论的高校行政服务中心建设研究——以右江民族医学院为例

随着飞速发展的信息时代的到来,传统的服务管理已经不能满足高校的业务运作,现今高校行政服务建设势必会随着知识、科技的不断更新而改变。业务流程再造理论(Business Processing Reengineering,BPR)在国外各领域的运用已经很成熟,促使国内的学者及研究型管理者进行探究,但目前国内高校在行政服务中心建设方面还有很大的改进空间。因此,本文以BPR理论为基础,分析右江民族医学院校务服务中心大学生服务中心行政服务建设现状,找出存在的问题,对低效率的流程提出优化和改进的对策,从而使高校行政服务实现业务办理科学、服务高效、师生满意的目标。     

'Frankie the Frog': the total transformation of a river basin as 'totalitarian' technology (Spain, 1946-1961)

After the Spanish Civil War (1936-1939), Francisco Franco's emphasis on dam building became so intense that it is still today associated with his dictatorial rule. Rather than being purely a personal obsession, however, this intensive period of reservoir construction was the result of the influential political role played by engineers from the early years of the regime. During the years 1946-1961 some of these engineers undertook the 'total transformation' of the Noguera Ribagorzana river basin in the Catalonian Pyrenees. But this explicitly 'totalitarian' project encountered important limitations posed both by competing state agencies and by the basin's geology. Analysing the efforts of these engineers allows for new understandings of the Francoist regime and of the place of science, technology, and the landscape within it.

互补性专利联盟是否必要——一个基于讨价还价许可模式的新见解

由互补性专利形成的专利联盟能够克服“专利丛林”问题,提高纵向产业链的经济效率是对专利联盟的一般共识。这一论断是建立在古诺标价模型基础之上的。本文建立了更加符合现实的关于专利许可的两阶段讨价还价博弈模型,得出的结论是无论下游市场是完全竞争市场还是寡头垄断市场,都存在一个弱占优战略均衡。均衡时,产业链联合利润达到最大,且产出等于专利联盟进行联合许可的产出,而总许可价格比专利联盟时的许可价格更低。 这意味着由传统的古诺互补品问题而引发的“古诺效应”并不成立,互补性专利的交易并不需要通过专利联盟许可来克服专利许可交易中出现的所谓诸如“专利丛林”、“费用叠加”、“专利挟持”、“反公地悲剧”等问题。

Facilitating communities of practice as social learning systems: a case study of trialling sustainable sanitation at the University of Technology Sydney (UTS)

While social learning is advocated as critical for inducing large-scale shifts toward sustainability, methodological issues associated with designing the opportunities for social learning or guidelines for practitioners seeking to facilitate such learning in cross-disciplinary teams working on sustainability-oriented projects are lacking. This paper draws on a two-year pilot project in Sydney, in which government, industry and academic partners collaborated to learn about the development potential of urine diversion (UD) systems in practice. The concept of ‘Communities of Practice’ was used to identify inherent challenges and opportunities for social learning. An outcome of the project has been the identification of overarching principles for designing opportunities for social learning in such projects, particularly the need (1) to facilitate community-oriented leadership, (2) to develop strategic exercises for collaborative engagement and (3) involvement of actors beyond the boundaries of the experiment to introduce novelty, diversity and cumulative learning opportunities.
