Interactive video usage on autism spectrum disorder training in medical education

This study aimed to compare the effects of interactive and non-interactive videos concerning the autism spectrum disorder on medical students’ achievement. It also evaluated the relation between the interactive videos’ interactivity and the students’ decision-making process. It used multiple methods, including quantitative and qualitative methods. The participants were 60 medical students, divided into two groups. One group watched an interactive video while the other watched a non-interactive video. Pre- and post-tests were used to evaluate the students’ relevant achievements in each group. Moreover, a think-aloud protocol was used to evaluate the decision-making process of the group who watched the interactive video. The pre- and post-test results indicated an increase in the achievements of students in the tested groups. Students who watched the interactive video were found to be more successful. Finally, watching interactive videos was shown to positively affect medical students’ decision-making process.     

Open service innovation and the firm's search for external knowledge

The concept of open innovation captures the increasing propensity of firms to work across their traditional boundaries of operation. This phenomenon has largely been studied from the viewpoint of manufacturing businesses while services have received much less attention despite the predominant role they play in advanced economies. This paper focuses on open innovation in services, both as a subsector of the economy and as a component of the activities of manufacturing firms. We study the open innovation practices of business services firms and then consider the implications for open innovation of the adoption of a service inclusive business model by manufacturing firms. Our analyses are based on a unique dataset with information on open innovation activities amongst UK firms. Overall, engagement in open innovation increases with firm size and R&D expenditure. Business services are more active open innovators than manufacturers; they are more engaged in informal relative to formal open innovation practices than manufacturers; and they attach more importance to scientific and technical knowledge than to market knowledge compared to manufacturing firms. Open innovation practices are also associated with the adoption of a service inclusive business model in manufacturing firms and service-integrated manufacturers engage in more informal knowledge-exchange activities. The paper contributes towards a reconceptualisation of open innovation in service businesses and a deeper evidence-based understanding of the service economy.     

Factors Affecting Psychosocial Adjustment of Deaf Students

Deafness is more than a medical condition. Recent theories have emphasized the importance of environmental factors on the psychosocial development of deaf children. As part of a larger scale study, this article aims to investigate the impact of the following variables on deaf students' psychosocial adjustment in Turkey: student-related background and experiential characteristics, parent-related variables, school-related factors, and teacher-related variables. The sample of 1,097 deaf students enrolled in the elementary, secondary, and high schools was drawn from 34 schools in 24 cities on a national geographical spread. The multiple regression analysis revealed that degree of hearing loss, additional handicap, and age at onset of deafness were negatively related to psychosocial adjustment of deaf students. However, there was a positive relationship between psychosocial variables and some of the independent variables, such as use of hearing aids, speech intelligibility, academic achievement, parental hearing status, and communication methods used at school. The findings of the study do not support a "pathological" view of deafness, suggesting that it was not deafness per se but that some environmental factors were also influential on the psychosocial adjustment of deaf students.     

Harem education and heterotopic imagination

Education can cease to be a showcase for political projects and start serving women’s lives only when the agency of women in their own education is acknowledged. In this paper I have addressed issues concerning harem education to emphasise that possible solutions to issues of girls’ education require an awareness concerning the history of girls’ education in different geographies. In this article, this agency is pursued in the homosocial production of knowledge in the harem, which is an exoticised space. Questioning the limitations and benefits of the concept of the harem is especially important in understanding processes such as the accommodation of public practices of education in women’s homes. Using Foucault’s concept of heterotopia, the harem is contextualised to shed light upon its liberating and dominating aspects, as a sphere where public and private practices of education converge.     

Diagnostic accuracy of UriSed automated urine microscopic sediment analyzer and dipstick parameters in predicting urine culture test results

Introduction

Urinary tract infection (UTI) is one of the most common types of infection. Currently, diagnosis is primarily based on microbiologic culture, which is time- and labor-consuming. The aim of this study was to assess the diagnostic accuracy of urinalysis results from UriSed (77 Electronica, Budapest, Hungary), an automated microscopic image-based sediment analyzer, in predicting positive urine cultures.

Materials and methods:

We examined a total of 384 urine specimens from hospitalized patients and outpatients attending our hospital on the same day for urinalysis, dipstick tests and semi-quantitative urine culture. The urinalysis results were compared with those of conventional semi-quantitative urine culture.

Results:

Of 384 urinary specimens, 68 were positive for bacteriuria by culture, and were thus considered true positives. Comparison of these results with those obtained from the UriSed analyzer indicated that the analyzer had a specificity of 91.1%, a sensitivity of 47.0%, a positive predictive value (PPV) of 53.3% (95% confidence interval (CI) = 40.8–65.3), and a negative predictive value (NPV) of 88.8% (95% Cl = 85.0–91.8%). The accuracy was 83.3% when the urine leukocyte parameter was used, 76.8% when bacteriuria analysis of urinary sediment was used, and 85.1% when the bacteriuria and leukocyturia parameters were combined. The presence of nitrite was the best indicator of culture positivity (99.3% specificity) but had a negative likelihood ratio of 0.7, indicating that it was not a reliable clinical test.

Conclusions:

Although the specificity of the UriSed analyzer was within acceptable limits, the sensitivity value was low. Thus, UriSed urinalysis results do not accurately predict the outcome of culture.     

The Effects of Simultaneous Prompting on Teaching Expressive Identification of Objects: An instructive feedback study

The present study examined whether the use of a simultaneous prompting procedure would result in an increase in the percentage of correct responses when expressively identifying first aid materials. A multiple probe design across behaviours and replicated across students was used. Three training sets with a total of nine first aid materials were presented to three students. Also, instructive feedback stimuli were presented during consequent events to increase the efficiency of instruction. The instructive feedback con tained the functions of the instructional materials. Maintenance effects were assessed 1, 2, and 4 weeks after training. The results showed that all students learned expressive identification of first aid materials and maintained them after training. Furthermore, all students acquired and maintained some of the instructive feedback stimuli presented to them during instruction.     

A scalable privacy-preserving recommendation scheme via bisecting k-means clustering

Privacy-preserving collaborative filtering is an emerging web-adaptation tool to cope with information overload problem without jeopardizing individuals’ privacy. However, collaborative filtering with privacy schemes commonly suffer from scalability and sparseness as the content in the domain proliferates. Moreover, applying privacy measures causes a distortion in collected data, which in turn defects accuracy of such systems. In this work, we propose a novel privacy-preserving collaborative filtering scheme based on bisecting k-means clustering in which we apply two preprocessing methods. The first preprocessing scheme deals with scalability problem by constructing a binary decision tree through a bisecting k-means clustering approach while the second produces clones of users by inserting pseudo-self-predictions into original user profiles to boost accuracy of scalability-enhanced structure. Sparse nature of collections are handled by transforming ratings into item features-based profiles. After analyzing our scheme with respect to privacy and supplementary costs, we perform experiments on benchmark data sets to evaluate it in terms of accuracy and online performance. Our empirical outcomes verify that combined effects of the proposed preprocessing schemes relieve scalability and augment accuracy significantly.
