This paper reviews two recent research studies on Portuguese New Technology Based Firms (NTBFs). Attention is given to the role and contribution of NTBFs to innovation. The main argument is that, by and large, NTBFs are less concerned with the introduction of major innovations and more with creative adaptive improvements to products and services based upon new technologies first introduced elsewhere. The empirical research found that Portuguese NTBFs are a recent phenomenon associated with diffusion of Electronics and Information Technologies (EIT) during the late 1980s. They perform a wide variety of knowledge-intensive activities, which enhance local users' adoption processes and they are associated with different forms of technology transfer through external linkages. Overall, NTBFs undertake a frequently unobserved role as technology searchers and acquirers that, pushed by idiosyncratic local niche market opportunities, selectively choose among and enhance technologies developed elsewhere, introducing them into the local market. 相似文献

This paper studies how productivity-enhancing agricultural technology affects urbanization by provoking structural change. We investigate these issues using a natural experiment in the United States. The results show that technologies which improve crop productivity lead to a less urbanized economy as economic activity relocates from manufacturing and services towards agriculture. The effects are highly persistent and are driven by the technology increasing agricultural labor demand. Our findings highlight the potentially unintended, disruptive force of innovative technologies. 相似文献

The rate of digital disruption is escalating and placing increasing pressure on organisations to adopt emerging technologies in order to improve their productivity and bottom-lines. Unfortunately, however, many organisations are often being seduced by the purported benefits of disruptive technologies often based on embellished or even falsified claims. This is particularly true in construction, where organisations are being required to embrace disruptive technologies (e.g. Building Information Modelling and Industry 4.0) to address performance and productivity issues. Unsubstantiated claims about expected benefits subvert the justification and benefits realisation process as the change management that is required is downplayed or ignored. It is, therefore, imperative that the business case as part of the process of evaluation, is based on evidence to enable the development of a change management and implementation strategy. In this paper, we present an overview of a longitudinal line of inquiry that sought to examine the benefits of disruptive technology, namely Systems Information Modelling (SIM). Our research revealed that more than a 90 % cost reduction to document electrical systems and a corresponding improvement in productivity was achieved. We suggest that engaging in the process of critical thinking, possessing a conscious awareness and healthy scepticism of technology places organisations in a position of control. As a consequence, organisations are better-positioned to understand the nature of technology and ‘how’ value can be generated from potential new ways of working. 相似文献

In this article visual technologies and their use in three reconstructions after an incident are linked with accountability issues. Conclusions are drawn on the relation between administration, the choice of technology to create and distribute visual occurrences, and society and how visualizations are used to frame accountability issues. 相似文献

The need for those working in a variety of settings to interact effectively with technical experts has grown dramatically in recent years as computers have become essential to the performance of an increasing broad range of professional work. This article presents a case of this sort of interprofessional interaction, exploring the process and outcomes of collaboration between technical professionals and educators working to bring Internet access to an urban public school district. Drawing on field note and interview data, the case reported here illustrates how differences in institutional routines and professional values can generate differing agendas, contrasting assumptions, and contrasting expectations concerning project products and outcomes among collaborators from different professional worlds. In the case we describe, these differences affected such central matters as the types and usefulness of technical resources to which users had access as well as users' confidence in the technology. The case also illustrates how aspects of this interprofessional conflict were addressed through an organizational change. The kinds of issues that arose in this project are likely to occur in a variety of professional settings; therefore, examination of this case provides insight into a variety of issues and dynamics that should be considered when embarking upon or analyzing any interprofessional collaborative effort, and particularly one that involves technical professionals. 相似文献

The emergence of novel and powerful digital technologies, digital platforms and digital infrastructures has transformed innovation and entrepreneurship in significant ways. Beyond simply opening new opportunities for innovators and entrepreneurs, digital technologies have broader implications for value creation and value capture. Research aimed at understanding the digital transformation of the economy needs to incorporate multiple and cross-levels of analysis, embrace ideas and concepts from multiple fields/disciplines, and explicitly acknowledge the role of digital technologies in transforming organizations and social relationships. To help realize this research agenda, we identify three key themes related to digitization—openness, affordances, and generativity—and, outline broad research issues relating to each. We suggest that such themes that are innate to digital technologies could serve as a common conceptual platform that allows for connections between issues at different levels as well as the integration of ideas from different disciplines/areas. We then summarize the contributions of the 11 papers presented in this Special Issue relating them to one or more of these themes and outlining their implications for future research. 相似文献

The licensing of university technologies to private firms has become an important part of the technology transfer mission of many universities. An inherent challenge for the technology licensing of universities is that potential licensees find it difficult to judge the early stage technologies and their ultimate commercial value. We reason that patent litigation against universities can have unintended signaling effects about the commercial value of its technologies and results in increased licensing income for the university. We ground this hypothesis in theory integrating signaling mechanisms from patent enforcement research into theoretical models explaining university technology licensing. Within our logic, the public and costly nature of patent litigation against universities creates strong, credible signals to potential licensees about the technologies of a university even if the signal was not created for that specific purpose. We isolate the signaling mechanism that is central to our theorizing by exploring two moderation factors that reveal additional information to potential licensees, i.e. the licensing track-record of the university and whether the lawsuit involves private firms as co-defendants. We test our theory with a unique dataset of 157 US universities and the 1408 patent infringement cases in which they were involved as defendants over the period 2005–2016. Results show that defending against claims of patent infringement enhances technology licensing revenues, particularly when universities are already adept at licensing technology and when they are co-defendants with private firms. 相似文献

There is surprisingly little attention in Information Technology ethics to respect for persons, either as an ethical issue
or as a core value of IT ethics or as a conceptual tool for discussing ethical issues of IT. In this, IT ethics is very different
from another field of applied ethics, bioethics, where respect is a core value and conceptual tool. This paper argues that
there is value in thinking about ethical issues related to information technologies, especially, though not exclusively, issues
concerning identity and identity management, explicitly in terms of respect for persons understood as a core value of IT ethics.
After explicating respect for persons, the paper identifies a number of ways in which putting the concept of respect for persons
explicitly at the center of both IT practice and IT ethics could be valuable, then examines some of the implicit and problematic
assumptions about persons, their identities, and respect that are built into the design, implementation, and use of information
technologies and are taken for granted in discussions in IT ethics. The discussion concludes by asking how better conceptions
of respect for persons might be better employed in IT contexts or brought better to bear on specific issues concerning identity
in IT contexts. 相似文献

In this essay, a new approach to the ethics of emerging information technology will be presented, called anticipatory technology ethics (ATE). The ethics of emerging technology is the study of ethical issues at the R&D and introduction stage of technology development through anticipation of possible future devices, applications, and social consequences. In the essay, I will first locate emerging technology in the technology development cycle, after which I will consider ethical approaches to emerging technologies, as well as obstacles in developing such approaches. I will argue that any sound approach must centrally include futures studies of technology. I then present ATE and some applications of it to emerging information technologies. In ATE, ethical analysis is performed at three levels, the technology, artifact and application levels, and at each levels distinct types of ethical questions are asked. ATE analyses result in the identification and evaluation of a broad range of ethical issues that can be anticipated in relation to an emerging information technology. This ethical analysis can then be used for ethical recommendations for design or governance. 相似文献

Industrial districts as local networks of small and medium enterprises (SMEs) rooted their competitiveness in a mix of economic relationships and social ties. Recently, network technologies have promised gains of efficiency through a reduction in transaction costs and showed new commercial opportunities for small firms. Despite the morphological similarities between industrial districts and network technologies, a longitudinal analysis of ICT diffusion within Italian districts shows that the foreseen convergence between the district economic model and new technologies should not be taken for granted. The observed specific evolutionary paths concerning technology innovation in local systems also opens-up issues of economic policy. 相似文献

Technological revolutions are dissected into three stages: the introduction stage, the permeation stage, and the power stage.
The information revolution is a primary example of this tripartite model. A hypothesis about ethics is proposed, namely, ethical
problems increase as technological revolutions progress toward and into the power stage. Genetic technology, nanotechnology,
and neurotechnology are good candidates for impending technological revolutions. Two reasons favoring their candidacy as revolutionary
are their high degree of malleability and their convergence. Assuming the emerging technologies develop into mutually enabling
revolutionary technologies, we will need better ethical responses to cope with them. Some suggestions are offered about how
our approach to ethics might be improved. 相似文献

In this paper we discuss the social and ethical issues that arise as a result of digitization based on six dominant technologies: Internet of Things, robotics, biometrics, persuasive technology, virtual & augmented reality, and digital platforms. We highlight the many developments in the digitizing society that appear to be at odds with six recurring themes revealing from our analysis of the scientific literature on the dominant technologies: privacy, autonomy, security, human dignity, justice, and balance of power. This study shows that the new wave of digitization is putting pressure on these public values. In order to effectively shape the digital society in a socially and ethically responsible way, stakeholders need to have a clear understanding of what such issues might be. Supervision has been developed the most in the areas of privacy and data protection. For other ethical issues concerning digitization such as discrimination, autonomy, human dignity and unequal balance of power, the supervision is not as well organized. 相似文献

This paper is as much about surveillance as about persuasive technologies (PTs). With regard to PTs it raises the question about the ethical limits of persuasion. It will be argued that even some forms of self-imposed persuasive soft surveillance technologies may be considered unethical. Therefore, the ethical evaluation of surveillance technologies should not be limited to privacy issues. While it will also be argued that PTs may become instrumental in pre-commitment strategies, it will also be demonstrated that the use of persuasive surveillance technologies in order to influence the users to become more compliant, to get their consent more easily or making it harder to opt out of the system does give rise to ethical issues. 相似文献
