In this case study, a collaborative risk method for information security management has been analyzed considering the common problems encountered during the implementation of ISO standards in eight Turkish public organizations. This proposed risk method has been applied within different public organizations and it has been demonstrated to be effective and problem-free. The fundamental issue is that there is no legislation that regulates the information security liabilities of the public organizations in Turkey. The findings and lessons learned presented in this case provide useful insights for practitioners when implementing information security management projects in other international public sector organizations. 相似文献

In the age of digital networks and databases, gathering data is no longer a differentiating attribute. Instead, the onus is upon creating knowledge and codifying it into the organizational routine. The central theme of this paper is to offer a systematic knowledge codification routine that embodies specific agent attributes and best re-engineering practices. The knowledge process re-engineering schema is proposed as a routine comprising extraction, transformation, and loading to encompass seeking knowledge inputs, converting them based on context, and codifying knowledge for organizational reuse. Using the organization as the primary unit of analysis, the scope of our discussion explicates an agent-mediated process re-engineering model of knowledge creation and codification. The proposed re-engineering captures the synthetic transformation of data into information, information into explicit knowledge, the use of explicit knowledge as an input to tacit knowledge, and the codification of tacit knowledge into explicit knowledge in an attempt to shift the ownership and control of knowledge from the individual to the organization. 相似文献

ABSTRACTIndividual innovativeness has become one of the most important employability skills for university graduates. In this paper, we focus on how students could be better prepared to be innovative in the workplace, and we argue that inquiry-based learning (IBL) – a pedagogical approach in which students follow the inquiry-based processes used by scientists to construct knowledge – can be effective for this purpose. Drawing on research which examines the social and cognitive micro-foundations of innovative behavior, we develop a conceptual model that links IBL and student innovativeness, and introduce three teacher-controlled design elements that can influence the strength of this relationship, namely whether an inquiry is open or closed, discovery-focused or information focused and individual or team-based. We argue that an open, discovery-focused and team-based inquiry offers the greatest potential for enhancing students’ skills in innovation. This paper has several implications for higher education research and practice. 相似文献

First‐year architecture students are expected to utilise visuospatial abilities to generate/construct, retain, rotate and manipulate space mentally and physically through physical and digital representations. This study of 57 female and 23 male participants was conducted to investigate first‐year architecture students’ visuospatial abilities by means of the Beck Depression Inventory, Logical Reasoning Test and Judgment of Line Orientation (JLO) test. Participants’ sexes, cognitive development level, depression scale scores, university entrance exam results, vision disorders, physical competences, art training prior to university and error types were the study’s main parameters. The results showed that academic scores of the participants both to enrol in the program and complete the first‐year studio did not correlate with their JLO scores. Nondepressed participants performed better in JLO. Error analyses demonstrated that there is a concentration on certain items according to the test stimulus line positions, especially in females. Those who reported limited physical and visual competency made more mistakes in the same items. The study concludes that sex, depression, and individual differences in physical and visual competency, and art training, are significant variables for visuospatial performance. Judging visuospatial parameters through spatial design exercises is different from having proper methods and instruments to assess the achievements of the students regarding those abilities in architectural design education. It is important to map students’ visuospatial abilities individually from a developmental perspective. There is a strong need to develop 4D psychometric instrument to assess visuospatial abilities. 相似文献

Privacy-preserving collaborative filtering schemes focus on eliminating the privacy threats inherent in single preference values, and the privacy risks in the multi-criteria preference domain are disregarded. In this work, we introduce randomized perturbation-based privacy-preserving approaches for multi-criteria collaborative filtering systems. Initially, the privacy protection methods efficiently used in traditional single-criterion systems are adapted onto multi-criteria ratings. However, these systems require intelligent protection mechanisms that are flexible and adapting to the structure of each sub-criterion. To achieve such a goal, we introduce a novel privacy-preserving protocol by adapting an entropy-based randomness determination procedure that can recover accuracy losses. The proposed protocol adjusts privacy-controlling parameters concerning the information inherent in each criterion. We experimentally evaluate the proposed schemes on three subsets of Yahoo!Movies multi-criteria preference dataset to demonstrate the effects of the proposed privacy-preserving schemes on both user privacy levels and prediction accuracy for differing sparsity rates. According to the obtained experimental outcomes, the proposed entropy-based privacy-preserving scheme can produce significantly more accurate predictions while maintaining an identical level of privacy provided by the traditional privacy protection scenario. The experimental results also confirm that the novel entropy-based privacy-preserving scheme maintains the confidentiality of personal preferences without severely compromising prediction accuracy. 相似文献

Ethnicity and, by extension, ethnic identity, are problematic concepts to define. This article explores self-defined boundaries of ethnic identity by framing ethnicity as a communicative process through a narrative study focusing on a particular refugee group called Meskhetian Turks. Twelve in-depth interviews were analyzed for emerging themes. The results revealed three inter-connected themes demonstrating the significance of (1) the past, (2) cultural preservation, and (3) a sense of community. Thus, the study demonstrated self-defined borders of ethnic identity and revealed ethnicity as a communicative process, whose emergence, preservation, and continuity depends solely upon communication. 相似文献

Popularity bias is an undesirable phenomenon associated with recommendation algorithms where popular items tend to be suggested over long-tail ones, even if the latter would be of reasonable interest for individuals. Such intrinsic tendencies of the recommenders may lead to producing ranked lists, in which items are not equally covered along the popularity tail. Although some recent studies aim to detect such biases of traditional algorithms and treat their effects on recommendations, the concept of popularity bias remains elusive for group recommender systems. Therefore, in this study, we focus on investigating popularity bias from the view of group recommender systems, which aggregate individual preferences to achieve recommendations for groups of users. We analyze various state-of-the-art aggregation techniques utilized in group recommender systems regarding their bias towards popular items. To counteract possible popularity issues in group recommendations, we adapt a traditional re-ranking approach that weighs items inversely proportional to their popularity within a group. Also, we propose a novel popularity bias mitigation procedure that re-ranks items by incorporating their popularity level and estimated group ratings in two distinct strategies. The first one aims to penalize popular items during the aggregation process highly and avoids bias better, while the second one puts more emphasis on group ratings than popularity and achieves a more balanced performance regarding conflicting goals of mitigating bias and boosting accuracy. Experiments performed on four real-world benchmark datasets demonstrate that both strategies are more efficient than the adapted approach, and empowering aggregation techniques with one of these strategies significantly decreases their bias towards popular items while maintaining reasonable ranking accuracy. 相似文献

An examination of the statistics indicates that Turkish women have made great strides with respect to their recruitment to positions at all levels in the higher education institutions of their country, particularly in such fields as medicine, the hard sciences, and engineering in which women in very many countries are usually thought to be underrepresented. The author attributes this achievement to the Republican ideology of post‐1923 Turkey, the opportunities which were opened to élite women by the correspondence of the latter with the developmental needs of the country, the availability of domestic service provided by non‐elite women, and the existence of family solidarity networks. Women, however, have not been so well represented in such fields as law and political science which, were traditionally close to the loci of political power. In recent years, however, with the expansion of the higher education system, competition between men and women for posts has greatly increased, and economic change and urbanization have dried up the supply of inexpensive domestic help and have stymied family solidarity networks. Thus academic women are increasingly beset by conflicts between their professional and their family roles. This new situation has caused Turkish women to lose ground with regard to recruitment to prestigious positions in higher education and to seek conservative Islamic solutions to the conflicts in question. Reforms based on a renewed Republican ideal are needed to improve the situation and to enable Turkish women academics to build on their past achievements. 相似文献

The present study was conducted to investigate the degree of effectiveness of cooperative learning instruction over a traditional
approach on 11th grade students' understanding of electrochemistry. The study involved forty-one 11th grade students from
two science classes with the same teacher. To determine students' misconceptions concerning electrochemistry, the Electrochemistry
Concept Test consisting of 8 open-ended and 12 multiple-choice questions was used as a pre-test and some students were interviewed.
According to the results, twenty-four misconceptions (six of them initially identified) about electrochemistry were identified.
The classrooms were randomly assigned to a control group (traditional instruction, 21 students) and an experimental group
(cooperative learning based on a constructivist approach, 20 students). After instruction, the same test was administered
to both groups as a post-test. The results from the t-test indicated that the students who were trained using cooperative
learning instruction had significantly higher scores in terms of achievement than those taught by the traditional approach.
According to the post-test and interviews, it was also found that instruction for the cooperative group was more successful
in remediation of the predetermined misconceptions. 相似文献

There is debate about whether the leadership style of the teacher or the learning style of the student affects academic achievement more. A large sample (n = 746) of eighth‐grade students in Istanbul, Turkey, participated in a study where the leadership style of the teacher was assessed in terms of people orientation and task orientation. The learning styles examined were: group, individual, visual, auditory, tactile, and kinesthetic. Multiple discriminant analysis indicated that teacher leadership style was the main factor affecting academic performance. No significant relationship was found between learning style and academic achievement. 相似文献
