    Information Technology in The Learning Economy -Challenges for Developing Countries

    Get PDF
    This paper inquires how the concept of the "learning economy" can be applied to the requirements of developing countries. The main purpose is to develop an analytical framework to better understand how learning and capability formation can foster industrial upgrading. Special emphasis is given to te spread of information technology (IT). We inquire under what conditions developing countries can use this set of generic technologies to improve their learning capabilities. We argue that information technology should not be regarded as a potential substitute for human skills and tacit knowledge. Instead, its main role should be to support the formation and use of tacit knowledge. In the paper we compare two stylised models of the learning economy, the Japanese versus the American model. The Japanese model is explicit in its promotion and exploitation of tacit knowledge, while the American model is driven by a permanent urge to reduce the importance of tacit knowledge and to transform it into information - that is into explicit, 4 well structured and codified knowledge. We show that each of these models has peculiar strengths and weaknesses. Developing countries need to develop their own hybrid forms of institutions that combine the advantages of both models in a way that is appropriate to their idiosyncratic needs and capabilities.information technology; learning; learning economy; knowledge; capabilities; networks; developing countries; economic development; industrial upgrading

    Evaluation in artificial intelligence: From task-oriented to ability-oriented measurement

    Full text link
    The final publication is available at Springer via http://dx.doi.org/ 10.1007/s10462-016-9505-7.The evaluation of artificial intelligence systems and components is crucial for the progress of the discipline. In this paper we describe and critically assess the different ways AI systems are evaluated, and the role of components and techniques in these systems. We first focus on the traditional task-oriented evaluation approach. We identify three kinds of evaluation: human discrimination, problem benchmarks and peer confrontation. We describe some of the limitations of the many evaluation schemes and competitions in these three categories, and follow the progression of some of these tests. We then focus on a less customary (and challenging) ability-oriented evaluation approach, where a system is characterised by its (cognitive) abilities, rather than by the tasks it is designed to solve. We discuss several possibilities: the adaptation of cognitive tests used for humans and animals, the development of tests derived from algorithmic information theory or more integrated approaches under the perspective of universal psychometrics. We analyse some evaluation tests from AI that are better positioned for an ability-oriented evaluation and discuss how their problems and limitations can possibly be addressed with some of the tools and ideas that appear within the paper. Finally, we enumerate a series of lessons learnt and generic guidelines to be used when an AI evaluation scheme is under consideration.I thank the organisers of the AEPIA Summer School On Artificial Intelligence, held in September 2014, for giving me the opportunity to give a lecture on 'AI Evaluation'. This paper was born out of and evolved through that lecture.

    The Dialogical Language of Law

    Get PDF
    We live in a dialogical world. The normative environment around us is many-voiced. Legal activities like drafting, negotiating, interpreting, judging, invoking, and protesting the law take place in dialogical encounters, all of which presuppose entrenched forms of social dialogue. And yet, the dominant modes of thinking about the law remain monological. How can we bring our legal conceptions into alignment with the dialogical world in which we live? The present article follows in the footsteps of a Bakhtinian dialogical theory of language that challenges the roots of contemporary positivist conceptions of law and language underpinning large swathes of legal academia and the legal profession—including recent approaches to legal interpretation called corpus linguistics. Against this backdrop, the article aims to develop a richer and more textured dialogical jurisprudence to encompass the various aspects, activities, and genres where legal language is employed

    Camera Creatures: Rhetorics of Light and Emerging Media

    Get PDF
    Camera Creatures addresses the new media landscape in which cameras, in most situations, outnumber pens. The dissertation argues that despite the accessibility and power of imagemaking devices, there persists in the humanities and social sciences a hesitation to engage the possibilities for composing with optical media. A number of factors contributing to this trend are addressed, including the preference for image analysis over imagemaking practices, persistent assumptions of the camera\u27s mechanical objectivity, and a tendency to teach visual invention as collage. As a counter-measure, a proposal is made for investment in the mediation of light, or \u27photonic rhetorics.\u27 To explore these effects in visual communication and the possibility of bringing them into practice, three emerging camera technologies are examined. The first, the photo app, focuses on the controversy surrounding embedded journalists who use social networks and the Hipstamatic camera phone application to relay stories of U.S. Marines deployed in Afghanistan. The chapter argues that the filters and shooting styles of these mobile apps encourage fluencies in the persuasive effects of light. The second camera technology, the video clip, addresses the long take as the predominant technique of everyday video-making. Film theory, video sharing trends, and circadian science contribute to a discussion of the rhythms of long-take shooting and its capability to expose both visual habits and the contingencies capable of disrupting them. The third site turns to video game \u27shooters\u27 and the virtual camera\u27s construction of \u27surrogate vision,\u27 which the author argues is a critical tool for understanding the future of mediated interactivity in both physical and digital landscapes. The dissertation concludes with a pedagogical section devoted to conscientious cheating. Alongside theories of deliberate practice, \u27cheating\u27 is repurposed for education, offering new ways of testing the \u27rules\u27 of optical composition while discovering opportunities to intervene in light\u27s constant mediation of perception

    Testosterone and vasopressin in men’s reproductive behavior

    Full text link
    One common practice used by researchers is to divide human reproduction into two major domains: mating and parenting. Adaptive problems men faced over the millennia may have produced evolutionary pressure for hormone responses and behavior that facilitate both mating and parenting, either separately or simultaneously. The sometimes competing domains of mating and parenting in men are often mediated by a number of the same hormones, such as testosterone (T) and arginine vasopressin (AVP). One aim of the current study was to examine differences in baseline levels of T and AVP between childless men who were not in an exclusive, romantic relationship and married fathers. Another aim was to examine differences in responses in these hormones as a function of relationship/parental status and mating versus parenting audiovisual stimuli. Sixty men, ages 21-44 years, completed the study. Thirty were single, childless men and 30 were fathers, 29 of whom were married. Participants provided saliva samples for T assay and urine samples for AVP assay before and after viewing one of two randomly assigned 15-minute videos. One video was aimed at mating efforts and included couples engaging in sexual activity. The other video was aimed at parenting efforts and included clips of babies/toddlers crying from receiving a vaccination needle. There was no significant difference in baseline T or AVP between the single, childless men and the married fathers. Also, there was no significant difference in T or AVP responses as a function of relationship/parental status or video condition. Interpretation of the results and conclusions are discussed

It provides a detailed yet intelligible discussion of what AI is and how it works, a history of its development, and a description of the wide variety of functions that it is designed to accomplish, stressing that AI applications are ubiquitous, both in the private and public sectors. Applications today include: health care, education, employment-related decision-making, finance, law enforcement, and the legal profession. The article underscores the importance of determining the validity of an AI application (i.e., how accurately the AI measures, classifies, or predicts what it is designed to), as well as its reliability (i.e., the consistency with which the AI produces accurate results when applied to the same or substantially similar circumstances), in deciding whether it should be admitted into evidence in civil and criminal cases. The article further discusses factors that can affect the validity and reliability of AI evidence, including bias of various types, “function creep,” lack of transparency and explainability, and the sufficiency of the objective testing of AI applications before they are released for public use. The article next provides an in-depth discussion of the evidentiary principles that govern whether AI evidence should be admitted in court cases, a topic which, at present, is not the subject of comprehensive analysis in decisional law. The focus of this discussion is on providing a step-by-step analysis of the most important issues, and the factors that affect decisions on whether to admit AI evidence. Finally, the article concludes with a discussion of practical suggestions intended to assist lawyers and judges as they are called upon to introduce, object to, or decide on whether to admit AI evidence

To achieve this, it was necessary to deconstruct the generic term leadership and examine the DNA of each of the various forms of exercising authority (including governance, leadership, management, and command). This revealed concepts that have become lost to contemporary leadership thought and a western theoretical spectrum that sometimes struggles to cope with the dynamism present in extreme contexts. Findings indicate that there is more to leadership than the characteristics and actions of a single individual and that it is not until the system, in its entirety is considered, that many of the opportunities for and challenges to successful mission completion are identified. Additionally, understanding the needs and aspirations of a broad spectrum of society is a necessary antecedent when compiling a list of those individual and collective capabilities required to generate successful outcomes. The study also highlights the importance of evolving perceptions of national security, arising from recent changes to sector definitions, and questions the current roles and utility, along with the fragmented nature, of standing national security assets. The conclusions are intended to complement the current body of scholarly leadership material by introducing the interactive Leadership Capstan to explain and shape the dynamic and complex forces at play during extreme contexts, breaking the leadership challenge into more manageable building blocks. The findings also identify those factors that are more likely to lead to thriving outcomes when the tendency is to address the presenting threats in a more transactional manner. This enhanced scholarly platform is then available to inform those development programmes charged with grooming future leaders and overcoming those deficiencies highlighted in the current policy instruments and structures that the nation employs during response operations
