The present study offers new input to the discussion of how entrepreneurship education and training programmes can be tailored to suit design professionals. To a large extent, existing entrepreneurship teaching for creative people is based on a traditional administrative management logic that often results in a clash between entrepreneurial demands and creative identities. The paper is based on the following rationale: the better we understand designers' reasoning and their struggles concerning becoming entrepreneurs, the better we are able to design entrepreneurship learning experiences that meet their needs. Since designers' career‐making tends to be highly driven by their strong sense of identity, the paper takes an identity perspective. The empirical foundation of the research is based on observation studies and phenomenological interviews conducted during an eight‐week entrepreneurship training program. Twenty‐five nascent design entrepreneurs with a professional background as designers participated in the voluntary programme. The paper offers novel and critical insights into designers' experiences of the entrepreneurial identity and reasoning as they participate in entrepreneurship training.  相似文献

Perrow’s normal accident theory suggests that some major accidents are inevitable for technological reasons. An alternative approach explains major accidents as resulting from management failures, particularly in relation to the communication of information. This latter theory has been shown to be applicable to a wide variety of disasters. By contrast, Perrow’s theory seems to be applicable to relatively few accidents, the exemplar case being the Three Mile Island nuclear power station accident in the U.S. in 1979. This article re‐examines Three Mile Island. It shows that this was not a normal accident in Perrow’s sense and is readily explicable in terms of management failures. The article also notes that Perrow’s theory is motivated by a desire to shift blame away from front line operators and that the alternative approach does this equally well.  相似文献

Workflow systems permit organization of many individual subtasks into a cohesive whole, in order to accomplish a specific mission. For many government and business missions, these systems are used to manage repetitive processes, such as large data-processing and exploitation pipelines. Government missions with strong interactions with the real world are extremely dynamic, as are all missions dealing with error-prone or changing data streams. We contribute a vision for discovery of new steps in adaptive workflow systems, suitability functions that can discover candidate alternatives, and a way forward for sourcing options for decision-makers, without the strong assumptions required by previous work. As data-processing workflows are shared, the sharing entities may find that certain parts of the workflow must be adapted to the new environment of mission. Extremely dynamic environments call for capabilities that support agile operations and pipeline sharing by making it possible to choose relevant actions when a situation invalidates the assumptions of current execution. We adapt some work in schema matching towards this problem, citing key differences between the two sets of challenges.  相似文献

According to Simon’s (1977) decision making theory, intelligence is the first and most important phase in the decision making process. With the escalation of information resources available to business executives, it is becoming imperative to explore the potential and challenges of using agent-based systems to support the intelligence phase of decision-making. This research examines UK executives’ perceptions of using agent-based support systems and the criteria for design and development of their “ideal” intelligent software agents. The study adopted an inductive approach using focus groups to generate a preliminary set of design criteria of “ideal” agents. It then followed a deductive approach using semi-structured interviews to validate and enhance the criteria. This qualitative research has generated unique insights into executives’ perceptions of the design and use of agent-based support systems. The systematic content analysis of qualitative data led to the proposal and validation of design criteria at three levels. The findings revealed the most desirable criteria for agent based support systems from the end users’ point view. The design criteria can be used not only to guide intelligent agent system design but also system evaluation.  相似文献

This is really a rather interesting question and, I believe, not one that we bother to ask ourselves nearly often enough. This may be because, suspiciously enough, for many of us it often just means “job security”. More importantly, we really need to consider what is understood by “information security” by the various stakeholders1 we engage with.  相似文献

This paper starts from the assumption that the accident risk run by traffic participants is under their own voluntary control. It then considers the effects to be expected from incentives given to drivers for having fewer accidents or no accidents at all. On the basis of a simple utility model of drivers' preferred risk levels, expected safety effects are derived for incentive schemes which vary in: (1) the nature of the accident criterion to be met; (2) the extent of the criterion (i.e., the length of the period required); (3) the magnitude of the incentive; and (4) whether the criterion is an individual or a group performance. Implications of the results of cost effectiveness to the incentive provider are discussed. It appears that there is no lack of incentive schemes that are theoretically expected to yield more returns, in terms of accident costs, than needs to be invested in the incentive funds.  相似文献

The number of single-bicycle crash victims is substantial in countries with high levels of cycling. To study the role of visual characteristics of the infrastructure, such as pavement markings, in single-bicycle crashes, a study in two steps was conducted. In Study 1, a questionnaire study was conducted among bicycle crash victims (n = 734). Logistic regression was used to study the relationship between the crashes and age, light condition, alcohol use, gaze direction and familiarity with the crash scene. In Study 2, the image degrading and edge detection method (IDED-method) was used to investigate the visual characteristics of 21 of the crash scenes. The results of the studies indicate that crashes, in which the cyclist collided with a bollard or road narrowing or rode off the road, were related to the visual characteristics of bicycle facilities. Edge markings, especially in curves of bicycle tracks, and improved conspicuity of bollards are recommended. STATEMENT OF RELEVANCE: Elevated single-bicycle crash numbers are common in countries with high levels of cycling. No research has been conducted on what cyclists need to see to avoid this type of crash. The IDED-method to investigate crash scenes is new and proves to be a powerful tool to quantify 'visual accessibility'.  相似文献

Abstract

No clear definition of ‘posture’ can be found in ergonomics literature. It may be regarded as the configuration of the body's head, trunk and limbs in space or as a ‘quasistatic biomechanical alignment’ (Rohmert and Mainzer 1986), depending on whether the particular context in which it is used is anatomical or biomechanical. The functional aspects of posture are highlighted by the definition of a ‘position adopted because it is appropriate for the task being performed’ (Corlett 1981). Yet, in any work situation, functional, geometric, and biomechanical aspects are as integral to the concept of posture as they are to the consequences for performance and comfort. A simple task posture model, describing the relationships between the various factors which influence working postures, is presented as an aid to workplace design, and two examples are given to show how the model can be applied to die demands of particular types of task. An analysis is also made of the factors involved in the exertion of force, including physiological, environmental, personal, and task factors, in order to give a better understanding of the influences of task and workplace on strength capability.  相似文献

The π-calculus with synchronous output and mixed-guarded choices is strictly more expressive than the π-calculus with asynchronous output and no choice. This result was recently proved by C. Palamidessi and, as a corollary, she showed that there is no fully compositional encoding from the former into the latter that preserves divergence-freedom and symmetries. This paper argues that there are nevertheless “good” encodings between these calculi. In detail, we present a series of encodings for languages with (1) input-guarded choice, (2) both input- and output-guarded choice, and (3) mixed-guarded choice, and investigate them with respect to compositionality and divergence-freedom. The first and second encoding satisfy all of the above criteria, but various “good” candidates for the third encoding—inspired by an existing distributed implementation—invalidate one or the other criterion. While essentially confirming Palamidessi's result, our study suggests that the combination of strong compositionality and divergence-freedom is too strong for more practical purposes.  相似文献

Innovation is a social and interactive process in which collaboration and exchange of knowledge and information play crucial roles. Two conflicting hypotheses have been raised in previous research: Burt's structural hole hypothesis and the density hypothesis. In brief, the former of these hypotheses builds upon arguments for open network structures in the acquisition of innovation; the latter one builds upon arguments for closed network structures for innovation. To shed some light on this state of confusion, this paper tests these two conflicting hypotheses on two separate measures of innovation in a service industry setting. One innovation measure is more incremental in nature and regards the implementation of employees' ideas. The other innovation measure is more radical in nature and regards new services. Findings suggest that social network measures are, indeed, powerful predictors of innovation and, further, that the impact of these are likely to be radically different depending upon the type and measure of innovation. Consequently, this paper recommends caution when studying the impact of social network measures upon innovation, and that more fine‐grained measurements in particular are needed rather than focusing upon inter‐relationships of an overly general and superficial nature.  相似文献

User participation in the design process may be an axiom of quality design but in the design of interactive, innovative computer systems, user participation may be neither feasible nor desirable. Here, user centred methodologies miss the point. If computers are a medium rather than a tool, then we need a new design paradigm that recognizes the difference between using a product and experiencing a show. In this paper the role of users in interactive systems design within the context of Multimedia product development is discussed. The main features of Multimedia product development are outlined through reference to an empirical study of two organizations and the role of users in the design process is discussed. Finally a different design paradigm is suggested.  相似文献

Seamless learning refers to the seamless integration of the learning experiences across various dimensions including formal and informal learning contexts, individual and social learning, and physical world and cyberspace. Inspired by the exposition by Chan et al. (2006) on the seamless learning model supported by the setting of one or more mobile device per learner, this paper aims to further investigate the meaning of seamless learning and the potential ways to put it in practice. Through a thorough review of recent academic papers on mobile-assisted seamless learning (MSL), we identify ten dimensions that characterize MSL. We believe that such a framework allows us to identify research gaps in the stated area. A practitioner interested in adopting an MSL design or doing a new design can use our analysis to situate the dimensional space where the constraints or parameters of his or her design problem lie, and look at relevant design and research-based evidence of other related MSL systems to refine her own design.  相似文献

Ethical communication during crisis response is often assessed by external perceptions of the organization's intentions, rather than an assessment of the organization's communicative behaviors. This can easily lead researchers to draw editorial conclusions about an organization's ethics in crisis response rather than accurately describing its communicative behaviors. The case of BP's 2010 oil spill in the Gulf of Mexico provides a prime example for the importance of accurately assessing the ethical content of an organization's crisis response because the ethics of BP's response have been discussed in news and academic sources; yet little direct examination of the ethical content in BP's response has occurred. The findings have implications for communication ethics, social media engagement, and crisis communication more generally.  相似文献

Recent diversity, equity, and inclusion (DEI) efforts have made some limited progress in addressing underrepresentation and unequal opportunities for minority members in the Information Systems (IS) academic community. The Association for Information Systems (AIS), as the preeminent global professional society for the IS discipline, is tasked with acting on behalf of its members and their colleagues to achieve equity and inclusion for its diverse membership. This editorial has two aims: (1) to share the extent to which positive changes have been made and also the extent to which underrepresentation still pervades the IS academic community, especially at the senior ranks and in positions of power, and (2) to propose a coordinated, strategic focus that our field, our journals and conferences, and our association (AIS) can take to further improve diversity and inclusion for both junior and senior minority colleagues.  相似文献
