The term informatics is used as an umbrella term to stand for the overlapping disciplinary areas of information systems, information management and information technology. The current paper is part of a series which documents an overarching attempt to develop a clearer and more sophisticated systematics for the area. It examines one of the foundation concepts of informatics – that of information – and aims to provide a definition for this concept based upon ideas from semiotics and communication theory. For this purpose we introduce the concept of a sign-system and consider the role such a system plays in human communication. We also highlight the fundamental difference between a communication system and an information system. To help ground our discussion and provide a necessary distance from the present-day concern with digital computing and communication networks we engage with the historiography of information. We consider the use of information in Neolithic times and describe the case of clay tokens in Ancient Sumeria as one of the earliest examples of information representation and manipulation. Examination of this case allows us to propose a number of universal features of information and ‘information technology’.  相似文献

This paper is part of a series examining the fundamental nature of informatics: a term used as a convenient umbrella term to stand for the overlapping disciplinary areas of information systems, information management and information technology. The aim of the current paper is to consider some of the universal features of information technology. This is accomplished in terms of a conceptual framework established in previous work. We ground the discussion in a significant historical case: that of Hollerith's electric tabulating system which constituted one of the earliest examples of automatic data processing. Through examination of this case and the technologies used we establish an interpretation of the essence of information technology in terms of formative acts of data representation and processing.  相似文献

关于公安情报学与情报学的关系学术界存在两种截然相反的观点:一是公安情报学是情报学的分支学科;二是公安情报学与情报学无从属关系,公安情报学应完全脱离情报学进行专业建设。文章从学科名称、产生背景、历史渊源、研究对象、研究内容、学科定位、学科重点、实践工作、方法技术、基础学科与学科建制等多方面对两者异同与关系作了分析,据此指出:两种观点各有其合理性,但也有失偏颇,公安情报学与情报学关系密切亦有较大区别,公安情报学不宜作为情报学的分支学科而应作为公安学的分支学科进行建设,但也不能完全脱离情报学,情报学是公安情报学重要的基础学科。  相似文献

【Purpose/significance】The study aims to strengthen the synergy between libraries & information agencies and think tanks, and guide the collaborative innovation operation between them. [Methods/procedures] This paper uses litera⁃ ture review, case study and AHP to expound the principle of the evaluation of collaborative innovation effect for libraries & information agencies and think tanks. Based on this, a system of collaborative innovation effect evaluation is established in six aspects of thinking, organization structure, information resources, human resources, technical resources and service for libraries & information agencies and think tanks. Then the case study was conducted with the collaborative innovation alli⁃ ance of Meteorological Disaster Forecasting and Warning. [Results/conclusions] This paper proposes a system of collabora⁃ tive innovation effect evaluation for libraries & information agencies and think tanks from the perspective of cooperative alli⁃ ances, which can provide a theoretical basis for the evaluation of collaborative innovation effects of other libraries & infor⁃ mation agencies and think tanks.  相似文献

Management effectiveness is strongly influenced by the quality and availability of the information resource available to managers. This is partially dependent upon the information and communication technologies which transport events, data and knowledge from isolated consciousness to individual and collective awareness. However, the use of these technologies rarely occurs in isolation. Rather, it is embedded in a far wider organisational context which recognises the politics of decision making and technical change, and the broader culture and experiences of organisations. Central to this is understanding how information technology (IT) investments cause organisations to reflect on the importance of their processes of communication and the value they place on information. A key part of this organisational flux acknowledges that IT applications are built on the existing systems, structure and past experiences of the organisation. Accordingly, investments in IT form part of an ongoing organisational development. Such intangible aspects create a dilemma for management in that they prove problematic to evaluate using conventional approaches to cost justification. By drawing on a series of case studies, questionnaires and interviews, this paper suggests a fresh approach to this dilemma by developing the concepts of dependency, legacy and heritage. The paper concludes by recognising that current approaches to investment appraisal emphasise a narrow, short-term perspective which focuses on a single investment, rather than on a continuous investment stream.  相似文献

An optimal procedure is established for the reconstruction of the angular object distribution in a given field of view (FOV). The object is coherently illuminated and located in the far zone of the receiving aperture. The procedure is “uniformly” optimal in the sense of minimizing the statistical r.m.s. difference between the object distribution, modeled as a random function of the angular coordinates and its reconstructed image, for each direction belonging to the FOV. The observable complex amplitude distribution of the field on the aperture is due in the general case not only to the incidentfield scattered by the object but also to background disturbance, or “angular noise”, randomly distributed inside and outside the FOV, and is affected by “measurement noise”, that is random errors introduced in measuring the aperture field. The reconstruction algorithm consists of summing a truncated series of special functions—prolate spheroidal for the linear case and their generalizations for two dimensional apertures—weighted by appropriate coefficients. These coefficients depend upon the observed aperture field and upon the relative power densities associated with the object field and the various types of noise. The series is truncated to a number of terms (“effective degrees of freedom” of the image) determined through an information theoretical method: each term of the series, suitably ordered, provides an information gain less than the preceding one, and the information gain goes rapidly to zero. A relationship between information transfer and mean squared error for each term in the image series is established. Numerical examples are discussed.  相似文献

The ethics in an information society is discussed from the combined viewpoint of Eastern and Western thoughts. The breakdown of a coherent self threatens the Western ethics and causes nihilism. Francisco Varela, one of the founders of Autopoiesis Theory, tackled this problem and proposed Enactive Cognitive Science by introducing Buddhist middle-way philosophy. Fundamental Informatics gives further insights into the problem, by proposing the concept of a hierarchical autopoietic system. Here the ethics can be described in relation to a community rather than a coherent self. The philosophical bridge between East and West is expected to solve the ethical aporia in the 21st century.  相似文献

This paper presents the results of an on-going research project aiming at developing GraviCS, an information system supporting local government and citizens in managing argumentations during the setting up of a Regional Natural Park in Southern Italy. We consider that organizational memory, structured within information systems supporting decision-making and action in organizational environments, can be a useful means for developing multilevel (individual, group, organizational) collaborative learning; in this sense the system architecture was designed referring to the organizational domain emerging in the decision making context of a Natural Park and was finalized to the dynamic representation of the organizational memory. Starting from the case study – the process for the Gravina Natural Park setting-up – , the paper describes the system's architecture and discusses some issues related to: possible dynamic representations of organizational memory; creation, use and storage of decision/learning histories.  相似文献

Beginning with the initial premise that as the Internet has a global character, the paper will argue that the normative evaluation of digital information on the Internet necessitates an evaluative model that is itself universal and global in character (I agree, therefore, with Gorniak- Kocikowska’s claim that because of its global nature “computer ethics has to be regarded as global ethics”. (Gorniak-Kocikowska, Science and Engineering Ethics, 1996). The paper will show that information has a dual normative structure that commits all disseminators of information to both epistemological and ethical norms that are in principle universal and thus global in application. Based on this dual normative characterization of information the paper will seek to demonstrate: (1) that information and internet information (interformation) specifically, as a process and product of communication, has an inherent normative structure that commits its producers, disseminators, communicators and users, everyone in fact that deals with information, to certain mandatory epistemological and ethical commitments; and (2) that the negligent or purposeful abuse of information in violation of the epistemological and ethical commitments to which its inherent normative structure gives rise is also a violation of universal rights to freedom and wellbeing to which all agents are entitled by virtue of being agents, and in particular informational agents.  相似文献

Research into free and open source software development projects has so far largely focused on how the major tasks of software development are organized and motivated. But a complete project requires the execution of “mundane but necessary” tasks as well. In this paper, we explore how the mundane but necessary task of field support is organized in the case of Apache web server software, and why some project participants are motivated to provide this service gratis to others. We find that the Apache field support system functions effectively. We also find that, when we partition the help system into its component tasks, 98% of the effort expended by information providers in fact returns direct learning benefits to those providers. This finding considerably reduces the puzzle of why information providers are willing to perform this task “for free.” Implications are discussed.  相似文献

话语是思想的表现形式,话语的贫困意味着思想的贫困。情报学的话语是人们在思考、表达情报学问题时的习惯性用语,它既标示出了情报学研究的内容,同时也标示出一个时期或一段时间内情报学研究的兴奋点。目前,情报学范式主要存在实用主义价值观与科学理性主义两种话语体系。依据解构主义理论,提出了拟像时代通过撒播、补充、实用创新情报学话语的逻辑,并据此提出了情报学话语创新的路径。  相似文献

The inclusion of informatics supporting trans‐border data flows (TDFs) in research and action related to the New World Information Order is essential. Documents prove the fact that information has been treated by developing countries as a critical element in the establishment of a New International Economic Order.

The author calls for the recognition of TDFs as an integral element of the debate over information. Such issues as free flow of information, national sovereignty, and dependent development are addressed. In the conclusion, it is argued that the International Telecommunication Union is well equipped to expand its domain of jurisdiction to TDFs in coordination with a maturing Intergovernmental Bureau for Informatics.  相似文献
