The ensemble Kalman filter is an ABC algorithm   总被引:1,自引:0,他引:1  
The ensemble Kalman filter is the method of choice for many difficult high-dimensional filtering problems in meteorology, oceanography, hydrology and other fields. In this note we show that a common variant of the ensemble Kalman filter is an approximate Bayesian computation (ABC) algorithm. This is of interest for a number of reasons. First, the ensemble Kalman filter is an example of an ABC algorithm that predates the development of ABC algorithms. Second, the ensemble Kalman filter is used for very high-dimensional problems, whereas ABC methods are normally applied only in very low-dimensional problems. Third, recent state of the art extensions of the ensemble Kalman filter can also be understood within the ABC framework.  相似文献

Despite the significance of relationship management in any information provision or exchange, public relations scholarship has typically focused on examining the underlying internal communication processes from a transactional perspective. These processes are frequently associated with organizational information dissemination, overlooking other critical contents to make strategic decisions. This study draws market information processing into the debate about internal communication, providing a greater understanding of how a relational approach can improve market intelligence dissemination. Results show that an effective management of market knowledge requires the use of such an approach, which in turn, cultivates the shared interpretation of market information and innovation performance. The findings stimulate fresh discussion about the nature and development of internal communication knowledge and practice.  相似文献

The internal conversation has a venerable place in the symbolic interactionist tradition but has been the focus of little empirical research by interactionists. After reviewing selected research on the internal conversation (most by noninteractionist sociologists or nonsociologists), we argue that interactionists ought to conduct research of our own to examine claims we have been making and to better understand social life. We propose some worthy areas and avenues of investigation.  相似文献

Globally, an estimated 734 million jobs will be required between 2010 and 2030 to accommodate recent and ongoing demographic shifts, account for plausible changes in labour force participation rates, and achieve target unemployment rates of at or below 4 per cent for adults and at or below 8 per cent for youth. The facts that most new jobs will be required in countries where “decent” jobs are less prevalent and workers in many occupations are increasingly subject to risks of automation further compound the challenge of job creation, which is already quite sizable in historical perspective. Failure to create the jobs that are needed through 2030 would put currently operative social security systems under pressure and undermine efforts to guarantee the national social protection floors enshrined in the Sustainable Development Goals (SDGs).  相似文献

The theme of this special section arose from the idea that interdisciplinary interactions, or the cross-fertilization of methods, philosophies, theories, and modes of practice across disciplines, can open out productive ways of addressing complex issues and wicked problems. Our call for papers reached out to public relations scholars and to researchers in other fields to submit articles at these generative intersections at different time. They were invited to reflect on traditional concerns, or current issues, or projected trends in public relations and elsewhere. As editors making a call to open boundaries, we invited participation along a spectrum of possible intersections whether of content, methods, pedagogy or technology. Taking different positions on that spectrum, the articles in the section examine the nature, engagement and evaluation of intersections. In writing this introduction, the editors took an overview of the articles in the light of three fundamental questions: “How and where does interdisciplinarity occur in public relations?”; “Are there indications of how public relations intersects with other fields to engage existing and potential future challenges?”; and “What principles might serve to evaluate answers to questions one and two?” In addition, we explore how each of the selected intersections in the articles might add value to public relations as a discipline and a practice.  相似文献

Most treatment for gambling disorder is provided on an outpatient basis. Only a small number of jurisdictions in North America provide higher levels of gambling treatment, such as residential or intensive outpatient (IOP) care, despite the potential need for these services. Further, there appear to be few guidelines for determining appropriate level of gambling treatment. The aim of the present study was to assess the appropriateness of higher levels of problem gambling care among clients receiving outpatient treatment. Problem gamblers and their therapists independently completed questionnaires that assessed the need and desire for residential and IOP treatment. About 42% of problem gambling outpatients noted that they would be “probably” or “definitely” willing to attend residential treatment, and about half indicated they would be equally likely to attend IOP. Therapists recommended about a third of their clients as appropriate for higher levels of care. For both client and therapist assessments, there was a significant association between desire or recommendation for level of treatment and severity of gambling and co-occurring problems. Further, therapist recommendations for level of care were significantly associated with client willingness to attend higher levels of treatment. Our data reveal the potential need for higher levels of care for problem gambling, as evaluated by clients and their therapists. Policy implications for the funding of residential and IOP treatment are discussed.  相似文献
