‘This could be our reality in the next five to ten years’: a blogpost platform as an expectation generation device on the future of insurance markets     

Gert Meyers  Ine Van Hoyweghen 《Journal of Cultural Economy》2018,11(2):125-140

William James (1919) characterises hypotheses as either live or dead. A hypothesis is live when it is taken into account as a ‘real possibility’. We follow James’ suggestion to not attribute intrinsic properties to hypotheses, but rather investigate how they came into being and look at the effects they generate. Expectations of digital technologies are a topic of vivid debate in the insurance industry. Before these expectations can become ‘live’, they have, in the first place, to be generated by market devices. We investigate how the reinsurance blogpost platform Open Minds functions as an ‘expectation generation device’ on the future of insurance markets. Combining Beckert’s work on the role of fictional expectations with the pragmatist turn in sociology of markets, we propose to study ‘expectation generation devices’, provoking expectations on economic markets. In our empirical analysis, we demonstrate the explicit fictional character of the Open Minds contributions, and analyse how a contained space of openness is generated to provoke expectations. We demonstrate how Open Minds can become live through circulation to other expectation generation sites in the insurance industry and beyond. We conclude by reflecting on the importance of expectation generation devices as a particular type of market devices.  相似文献   

Clustering small-sized collections of short texts     

Lili Kotlerman  Ido Dagan  Oren Kurland 《Information Retrieval》2018,21(4):273-306

The need to cluster small text corpora composed of a few hundreds of short texts rises in various applications; e.g., clustering top-retrieved documents based on their snippets. This clustering task is challenging due to the vocabulary mismatch between short texts and the insufficient corpus-based statistics (e.g., term co-occurrence statistics) due to the corpus size. We address this clustering challenge using a framework that utilizes a set of external knowledge resources that provide information about term relations. Specifically, we use information induced from the resources to estimate similarity between terms and produce term clusters. We also utilize the resources to expand the vocabulary used in the given corpus and thus enhance term clustering. We then project the texts in the corpus onto the term clusters to cluster the texts. We evaluate various instantiations of the proposed framework by varying the term clustering method used, the approach of projecting the texts onto the term clusters, and the way of applying external knowledge resources. Extensive empirical evaluation demonstrates the merits of our approach with respect to applying clustering algorithms directly on the text corpus, and using state-of-the-art co-clustering and topic modeling methods.  相似文献

Can textured insoles improve ankle proprioception and performance in dancers?     

Nili Steinberg  Gordon Waddington  Roger Adams  Janet Karin  Rezaul Begg  Oren Tirosh 《Journal of sports sciences》2016,34(15):1430-1437

With the aim of determining both the acute and the chronic effects of textured insoles on the ankle discrimination and performance ability of dancers, 60 ballet dancers from the Australian Ballet School, aged 14–19 years, were divided into three groups (two intervention groups and a control group), age- and level-matched. In the first 5 weeks (weeks 1 to 5), the first intervention group (GRP1) was asked to wear textured insoles in their ballet shoes and the second intervention group (GRP2) was not given textured insoles to wear. In the next 5 weeks (weeks 6 to 10), GRP2 was asked to wear the same type of textured insoles and GRP1 did not wear the textured insoles. The control group (CTRL) did not wear textured insoles during the whole 10 weeks. All participants were tested preintervention, after 5 weeks and after 10 weeks for ankle discrimination score (AUC scores). Dance performance was assessed by 5–7 dance teachers. Pre-to-post change in AUC scores was significantly greater for the groups wearing insoles than for the controls (P = .046) and the size of pre-to-post changes did not differ between the two intervention groups (P = .834). Significant correlation was found between ankle discrimination score and performance scores, using the textured insoles (r = .412; P = .024). In conclusion, the stimulation to the proprioceptive system arising from textured insoles worn for five weeks was sufficient to improve the proprioceptive ability and performance ability of ballet dancers.  相似文献   

Authoritarianism, perceived threat and exclusionism on the eve of the Disengagement: Evidence from Gaza   总被引：1，自引：0，他引：1  

Canetti D  Halperin E  Hobfoll SE  Shapira O  Hirsch-Hoefler S 《Int J Intercult Relat》2009,33(6):463-474

Major political events such as terrorist attacks and forced relocation of citizens may have an immediate effect on attitudes towards ethnic minorities associated with these events. The psychological process that leads to political exclusionism of minority groups was examined using a field study among Israeli settlers in Gaza days prior to the Disengagement Plan adopted by the Israeli government on June 6, 2004 and enacted in August 2005. Lending credence to integrated threat theory and to theory on authoritarianism, our analyses show that the positive effect of religiosity on political exclusionism results from the two-staged mediation of authoritarianism and perceived threat. We conclude that religiosity fosters authoritarianism, which in turn tends to move people towards exclusionism both directly and through the mediation of perceived threat.  相似文献

Design and implementation of multi-campus,modular master classes in biochemical engineering     

Niek Wuyts  Dorine Bruneel  Myriam Meyers  Etienne Van Hoof  Leander De Vos  Greet Langie 《European Journal of Engineering Education》2015,40(4):400-409

The Master of Science in engineering technology: biochemical engineering is organised in KU Leuven at four geographically dispersed campuses. To sustain the Master's programmes at all campuses, it is clear that a unique education profile at each campus is crucial. In addition, a rationalisation is required by increased cooperation, increased exchange of lecturers, and increased student mobility. To achieve this, a multicampus education system for the M.Sc. in engineering technology: biochemical engineering was developed by offering modules that are also available for students of other campuses. Such a module is primarily based on the research expertise present at the campus. In the development, special attention has been given to the optimal organisation of the modules, evaluation, required modifications of the current curricula, and the practical consequences for students following the module at another campus. Even in the first year of implementation, around 30% of the students followed a multicampus module, which indicates the potential success of the multicampus concept described here.  相似文献   

The challenges of undergraduate online learning experienced by older workers in career transition     

Christopher A. Meyers  Richard G. Bagnall 《International Journal of Lifelong Education》2017,36(4):442-457

This paper presents the findings of a research project on older workers transitioning into work as vocational educators through online undergraduate university study. The study involved interpretive phenomenological analysis of the experiences of 10 older learners. Their experience of online learning was found to be shaped by diverse influences and to comprise three distinct but interrelated elements: their use of technology, their use of hypermedia and their independent learning. Challenges raised by each of these elements called for a distinctive response from the university, respectively: short-term, readily available technical advice and support; tutoring to develop Web navigation and exploration skills, or the provision of selected readings; and opportunities for online or face-to-face dialogical engagement with others. Recommendations for the online provision of higher education for such learners, then, pointed to the need for an appropriately distinctive response to challenges in each of the three elements: the use of technology calling for individualised and immediate responsiveness to learner issues; the use of hypermedia calling for aggregated advice and resources prepared in advance; and independent learning calling for the prior structuring of opportunities for interactive engagement. Further research is suggested focusing on the relative cost and effectiveness of different approaches to addressing those needs.  相似文献   

AI assisted ethics     

Amitai Etzioni  Oren Etzioni 《Ethics and Information Technology》2016,18(2):149-156

The growing number of ‘smart’ instruments, those equipped with AI, has raised concerns because these instruments make autonomous decisions; that is, they act beyond the guidelines provided them by programmers. Hence, the question the makers and users of smart instrument (e.g., driver-less cars) face is how to ensure that these instruments will not engage in unethical conduct (not to be conflated with illegal conduct). The article suggests that to proceed we need a new kind of AI program—oversight programs—that will monitor, audit, and hold operational AI programs accountable.  相似文献
