A Wikipedia powered state-based approach to automatic search query enhancement     

Kyle Goslin  Markus Hofmann 《Information processing & management》2018,54(4):726-739

This paper describes the development and testing of a novel Automatic Search Query Enhancement (ASQE) algorithm, the Wikipedia N Sub-state Algorithm (WNSSA), which utilises Wikipedia as the sole data source for prior knowledge. This algorithm is built upon the concept of iterative states and sub-states, harnessing the power of Wikipedia’s data set and link information to identify and utilise reoccurring terms to aid term selection and weighting during enhancement. This algorithm is designed to prevent query drift by making callbacks to the user’s original search intent by persisting the original query between internal states with additional selected enhancement terms. The developed algorithm has shown to improve both short and long queries by providing a better understanding of the query and available data. The proposed algorithm was compared against five existing ASQE algorithms that utilise Wikipedia as the sole data source, showing an average Mean Average Precision (MAP) improvement of 0.273 over the tested existing ASQE algorithms.  相似文献   

Attitudes and experiences of parents regarding inclusive and special school education for children with learning and intellectual disabilities     

Barbara Gasteiger-Klicpera  Christian Klicpera  Markus Gebhardt  Susanne Schwab 《International Journal of Inclusive Education》2013,17(7):663-681

In a survey, 840 parents of children with cognitive deficits who were educated either in special schools or in inclusive classes were asked to assess their children's school experiences. The results showed an overall high degree of satisfaction with the schooling, but there were marked differences among the parents' assessments depending on the degree of learning disabilities and on the type of school. Satisfaction with their children's social experiences and satisfaction with the special education curriculum depend on these two factors. All in all, many parents of children in inclusive classes were satisfied with their children's schooling than those of children in special schools. The analysis of the causes for discontent showed that dissatisfied parents had chosen the type of school under less favourable conditions and a larger part of them are still not convinced of this necessity of additional help. This applied to parents of pupils in inclusive classes as well as to those of pupils in special schools. Furthermore, parents of children with German as a second language showed a higher degree of discontent than others.  相似文献   

Parent stress and satisfaction with early intervention services for children with disabilities – a longitudinal study from Germany     

Klaus Sarimski  Manfred Hintermair  Markus Lang 《欧洲特需教育杂志》2013,28(3):362-373

This study assessed parent–child and family-related stress at two points of time and analysed relationships between stress, child and family characteristics and parent satisfaction with early intervention services. In Germany, 125 parents of young children with intellectual disabilities, hearing impairment or visual impairment responded to a questionnaire. Eighty-seven parents agreed to participate in the second survey. Results indicated that (a) perceived parenting competence is associated with general self-efficacy and satisfaction with professional support, (b) parent–child interactional stress increased with time, specifically in families with children with intellectual disability or visual impairment, (c) the level of satisfaction with amount and quality of family support was low in a considerable subgroup of parents, (d) regression analyses support predictive relationships among parent–child stress, family-related stress, perceived parenting competence and satisfaction with early intervention services.  相似文献   

The pedagogic signature of special needs education     

Sabine Weiß  Markus Kollmannsberger  Thomas Lerche  Viktor Oubaid  Ewald Kiel 《欧洲特需教育杂志》2013,28(2):200-219

The goal of the following study is to identify a pedagogic signature, according to LS Shulman, for working with students who have special educational needs. Special educational needs are defined as significant limitations in personal development and learning which require particular educational measures beyond regular education. The development of a pedagogic signature should create an identity and provide guidance, particularly for teachers who are working in the context of inclusive schools with no prior knowledge or training in this regard. The study is carried out against the background of the structural uncertainty of the teaching profession and takes into consideration existing normative, theoretical and empirical approaches in education. Existing research regarding demands is largely theoretical, while empirical research is rudimentary. The present study used a multi-method approach to identify demands for working with students with special educational needs. Experts in the areas of learning disabilities and emotional/behavioural disorders completed an instrument from the field of industrial and organisational psychology, quantifying and weighting professional demands on teachers according to their importance. The results were added and validated through group discussions, creating a demand profile. By combining the results with the dimensions of a signature pedagogy, according to Shulman, it is apparent that surface structure and deep structure play a minor role in the perceptions of special needs teachers. The central importance of the implicit structure is characteristic of the pedagogic signature. This importance is represented by the target group’s emphasis on demands such as having an appreciative leadership or authenticity. An even greater emphasis is placed on the aspect of attitude – this is having a humanistic ethos. The demand profile and the resulting consequences for the practice of teaching will be considered with a view towards current problems and questions in research and practice, and particularly with regard to inclusion.  相似文献

Automated camera network design for 3D modeling of cultural heritage objects     

Bashar Alsadik  Markus Gerke  George Vosselman 《Journal of Cultural Heritage》2013,14(6):515-526

Image-based modeling is an appropriate technique to create 3D models of cultural heritage objects, which starts with the basic task of designing the camera network. This task is, however, quite crucial in practical applications because it needs a thorough planning and a certain level of experience. The optimal camera network is designed when certain accuracy demands are fulfilled with a reasonable effort, namely keeping the number of camera shots at a minimum. In this study, we report on the development of an automated method for designing the optimal camera network for a given cultural heritage building or statue. Starting from a rough point cloud derived from a video image stream, the initial configuration of the camera network is designed, assuming a high-resolution HR state-of-the-art non-metric camera. To improve the image coverage and accuracy, we use a mathematical non-linear optimization with constraints. Furthermore, synthetic images are created to guide the camera operator to the designed images. From the first experimental test, we found that a target accuracy of 10 mm could be maintained although the initial number of more than 300 high-resolution images got reduced to less than 90 for the final, optimized network.  相似文献   

Fragments of your communication: Email,vmail, and fax     

M. Lynne Markus  Tora K. Bikson  Maha El‐Shinnawy  Louise L. Soe 《The Information Society》2013,29(4):207-226

Abstract

How are new media, such as electronic mail, voice mail, and fax, used when people have access to several of them simultaneously? This paper reports findings from a field study of media use in four sizable subunits within two large organizations where most employees had access to email, vmail, and fax. Respondents tended to use multiple electronic media rather than relying on one. However, they also showed a tendency to prefer one medium for asynchronous communication and to use the others for occasional, specialized purposes. Further, there were considerable differences across subunits in typical media use patterns. Although respondents expressed strong desires for multimedia integration, this study suggests that technological integration may not necessarily result in seamless, collaborative work.  相似文献   

Letter from Rob Kling-Editor-in-Chief

Abstract

Individuals who have ready access to three new communication media— email, vmail, and fax—may elect to use only one medium, or two or more in combination. Users make choices based on evaluations of the utility of each medium for their communication tasks (a function of the types of work they perform). Individuals may assess technological characteristics to evaluate the technological utility of each medium. However, since communication media require multiple users, individuals also may be expected to assess characteristics of the user community to evaluate the social utility of each medium. Social utility may be influenced by people's perceptions of the existence of a critical mass of media users, and by the social influence of their peers and superiors. This study finds that perceptions of the technological and social utility of email, vmail, and fax are relatively independent of the types of work people perform. Social utility explains media usage somewhat better than technological utility, except in the case of email. Thus, the concept of social utility should be given more attention in future investigations of media choice.  相似文献   

What makes companies pursue an Open Science strategy?     

Markus Simeth  Julio D. Raffo 《Research Policy》2013

Whereas recent scholarly research has provided many insights about universities engaging in commercial activities, there is still little empirical evidence regarding the opposite phenomenon of companies disseminating scientific knowledge. Our paper aims to fill this gap and explores the motivations of firms that disclose research outcomes in a scientific format. Besides considering a dimension internal to the firm, we focus particularly on knowledge sourcing from academic institutions and the appropriability regime. We conduct an econometric analysis with firm-level data from the fourth edition of the French innovation survey (CIS) and matched scientific publications for a sample of 2512 R&D performing firms from all manufacturing sectors. This analysis provides evidence that firms are more likely to adopt academic principles if they need to access scientific knowledge that is considered important for their innovation development, whereas the mere existence of collaborative links with academic institutions is not a strong determinant. Furthermore, the results suggest that the inclination of firms to publish is sensitive to the level of knowledge spillovers in a sector and the effectiveness of legal appropriation instruments.  相似文献   

“Fun slipping into the doctor's role”—The relationship between sonoanatomy teaching and professional identity formation before and during the Covid-19 pandemic     

Dogus Darici  Markus Missler  Anna Schober  Max Masthoff  Hans Schnittler  Martina Schmitz 《Anatomical sciences education》2022,15(3):447-463

The various psychological dimensions of professional identity formation (PIF) are an important aspect of the study course for undergraduate medical students. Anatomical learning environments have been repeatedly shown to play a critical role in forming such an identity; however, relevance of PIF during sonoanatomical training remains underexplored. At the end of their basic anatomy studies, third-semester medical students took part in a four-day block course on anatomy and imaging. Anatomical content was revised in small groups using peer teaching and imaging methods, including one hour of hands-on sonoanatomy sessions each day. On-site sonoanatomy was identified as an excellent format to support students' transition from the pre-clinical to clinical phase as medical experts-to-be. Students enjoyed practical exercises and the clinical input, which increased their interest in the medical profession and their academic studies. This study further examined the effects of the transition into an online-only format, necessitated by the current Covid-19 pandemic. A comparison was made between the quantitative and qualitative evaluation data, and the written results of examinations of several on-site (n = 1096, mean age = 22.4 years ± 2.18), and online-only cohorts (n = 230, mean age = 22.6 years ± 2.21). The online-only transition led to a reduction of all PIF-related variables measured, losing identity-related variables, increasing students' stress levels, and reducing their long-term academic performance. Together, this study demonstrates presence of PIF in undergraduate sonoanatomy teaching, and cautions against the uncritical online-only substitution of hands-on learning environments.  相似文献
