Using Photography To Explore Hidden Realities and Raise Cross-Cultural Sensitivity in Future Teachers

This study explored the influence of residency status (outsider) and prior cross-cultural experiences on how the neighborhoods of students are perceived by future teachers. The study participants consisted of 18 graduate teacher education mentors and their 18 high school mentees. The data sources included 820 black and white photographs and 82 photo captions generated by the study participants, mentee/mentor group discussions, and the graduate students’ weekly reflective journals, bi-weekly facilitated discussions and peer debriefings. The study found that subconscious realities based on prior cross-cultural experiences (or the lack thereof) are more significant factors than residency status when making value judgment about the neighborhoods of “others.” Elinor L.

Freedom and Privacy in Ambient Intelligence

This paper analyzes ethical aspects of the new paradigm of Ambient Intelligence, which is a combination of Ubiquitous Computing and Intelligent User Interfaces (IUI’s). After an introduction to the approach, two key ethical dimensions will be analyzed: freedom and privacy. It is argued that Ambient Intelligence, though often designed to enhance freedom and control, has the potential to limit freedom and autonomy as well. Ambient Intelligence also harbors great privacy risks, and these are explored as well.     

Relational marketing in knowledge-intensive business services: an analysis of the computer services sector

This paper addresses the marketing approaches adopted by Knowledge-Intensive Business Services (KIBS) companies, whose main production factor and outcome is knowledge. Given the key role that client-provider cognitive interactions play in the provision of such services, the study adopts the conceptual framework of Service-Dominant (S-D) logic, that the recent literature considers being fully in line with the core characteristics of KIBS companies. Starting from the assumption that service is the fundamental basis of any economic exchange, this logic suggests a shift from the traditional ‘market to’ approach, which has been developed for tangible goods, to a ‘market with’ approach, where customers and providers collaborate along the whole marketing process. The research was carried out by means of a multiple case study of 20 small computer services companies in Italy, and aimed to understand if (and to what extent) the marketing initiatives of such companies are consistent with the S-D logic, and to discuss the major challenges that they have to face in order to follow the new logic.     

Development of terminological resources for expert knowledge: a case study in mining

In this paper we outline an approach to application of ontology in knowledge management. The University of Belgrade Faculty of Mining and Geology research team has developed a terminological resource to support knowledge management in mining engineering. Mining engineering, like all other engineering disciplines, needs comprehensive, consistent and standardized definitions of terms for efficient knowledge management and interoperability among various related IT applications. This goal can best be reached by terminological resources in electronic form organized as thesauruses or ontologies. The resource used to illustrate this approach, RudOnto, is a system of ontologies developed for mining engineering and their application in mining equipment and mine safety domains. Key benefits of applying ontologies in knowledge management, aside from securing interoperability, are enhancement of browsing/searching functions, and reuse and structuring capabilities. Through export to several specific formats, RudOnto ontologies offer the possibility of generating stand-alone terminological resources or ontologies in specific sub-fields, such as mining equipment, mine safety and geostatistics.

Customer’s role in knowledge management and in the innovation process: effects on innovation capacity and marketing results

Scholars have acknowledged customer knowledge management (CKM) as a key strategic resource for improving innovation and supporting long-term customer relationship management. This study provides a deeper understanding of the internal antecedents of business innovation capacity overcoming previous approaches. A model that had not previously been tested was used to analyse the role of customer collaboration and CKM – measured as a second-order construct – in innovation processes and marketing results. To test the model, structural equation modelling (partial least squares) was applied to a random sample of 210 Spanish companies. Results confirm that CKM and customer collaboration are antecedents of innovation capacity and marketing results. Furthermore, the effect of CKM is greater than the effect of customer collaboration. This paper provides a basis for managers to encourage innovation in their companies and explains how managers can improve marketing results.     

Corneal relaxing incision combined with phacoemulsification and IOL implantation

Objective: To analyze the effectiveness and safety of corneal relaxing incisions (CRI) in correcting keratometric astigmatism during cataract surgery. Methods: A prospective study of two groups: control group and treatment group. A treatment group included 25 eyes of 25 patients who had combined clear corneal phacoemulsification, IOL implantation and CRI. A control group included 25 eyes of 25 patients who had clear corneal phacoemulsification and IOL implantation.Postoperative keratometric astigmatism was measured at 1 week, 1 month, 3 months and 6 months. Results: CRI significantly decreased keratometric astigmatism in patients with preexisting astigmatism compared with astigmatic changes in the control group. In eyes with CRI, the mean keratometric astigmatism was 0.29±0.17 D (range 0 to 0.5 D) at 1 week, 0.41±0.21 D (range 0 to 0.82 D) at 1 month, respectively reduced by 2.42 D and 2.30 D at 1 week and 1 month postoperatively (P=0.000, P=0.000), and postoperative astigmatism was stable until 6 months follow-up. The keratometric astigmatism of all patients decreased to less than 1.00 D postoperatively. Conclusions: CRI is a practical, simple, safe and effective method to reduce preexisting astigmatism during cataract surgery. A modified nomogram is proposed. The long-term effect of CRI should be investigated.     

Experienced teachers’ expectations about the potential effectiveness of spelling exercises

In order to investigate what issues might be important for experimental training research, a group of experienced remedial teachers was asked to evaluate the potential effectiveness of various spelling exercises. After addressing some general questions about spelling exercises for Dutch poor spellers, they made rankings of several sets of exercises on the basis of the expected effectiveness. The teachers had to give their responses based on their own experiences and with a specific child with poor spelling in mind. The results show that the teachers emphasize the importance of providing rules in spelling exercises, but also agree that poor spellers often have serious difficulties in applying these rules in spelling. Furthermore, the rankings show that exercises with a combination of rule-based strategies and showing the whole orthographic pattern of the word are considered to be most effective. Learning to memorize the word without showing the spelling of the word was considered to be the least effective. Surprisingly, individual characteristics of the children did not seem to have any influence on the ranking of the exercises. It is concluded that exploiting the experience and knowledge of teachers may be good, but is only the first step for further research on the effectiveness of exercises for poor spellers.     

No evidence for overshadowing or facilitation of spatial pattern learning by visual cues

Two experiments were conducted to examine the effects of redundant and relevant visual cues on spatial pattern learning. Rats searched for hidden food items on the tops of poles that formed a square (Experiment 1) or a checkerboard (Experiment 2) pattern. The experimental groups were trained with visual cues that specified the locations of the baited poles. All groups were tested without visual cues so that any overshadowing or facilitation of spatial pattern learning by visual cues could be detected. Spatial choices were controlled by the spatial pattern and by the visual cues in both experiments. However, there was no evidence of overshadowing or facilitation of spatial pattern learning by visual cues in either experiment. The results are consistent with the idea that the representation of the spatial pattern that guides choices is not controlled by the same learning processes as those that produce associations between visual cues and food locations.
