Key block theory application for rock slope stability analysis in the foundations of medieval castles in Slovakia     

Vladimír Greif  Ján Vlčko 《Journal of Cultural Heritage》2013,14(4):359-364

This research investigates the stability of rock slopes in the foundations of selected medieval castles in Slovakia. In the first phase, static analysis of the 45 selected medieval castle rock slopes was performed, where more than 12,000 potentially unstable blocks were analyzed and the factor of safety in static condition was calculated using the key block theory implemented in the Kbslope module of PTworkshop software. Based on results of the static stability analysis, a pseudo-static analysis was performed adopting the seismic acceleration in accordance with Slovak Technical Standards – Seismic actions on structures. This was implemented by calculating the vectors of horizontal force acting upon shear failure in the direction of the slope face with a zero vertical component. When non-finite and tapered blocks were ignored, the results proved that 14% of the 12,217 blocks investigated under static conditions could be considered unstable. This number increased to 23% under pseudo-static conditions, when seismic acceleration was implemented in the stability calculations. A detailed stability assessment of the Gymes Castle located in western Slovakia was carried out with delineation of blocks prone to rock sliding and proper stabilization methods, based on joint sets orientation measurements performed on the 3D point cloud generated by laser scanner.  相似文献

A mentor’s aid in developing the competences of teacher trainees   总被引：1，自引：0，他引：1  

Milena Valenčič  Janez Vogrinc 《Educational studies》2007,33(4):373-384

The induction period is a very important time in the career of a teacher and has a long‐term influence on the teacher’s professional development, efficacy, job satisfaction and the length of his/her career. One of the key roles in this period is played by the trainee’s mentor. This paper presents the results of the extensive project ‘Partnership of Faculties and Schools’, carried out at the Pedagogical Faculty, University of Ljubljana, with the financial support of the European Social Fund and the Slovenian Ministry of Education, Science and Sport. We studied an induction project involving 361 teacher trainees and 331 mentors. The study reveals the trainees’ expectations towards their mentors and the mentors’ and trainees’ evaluations of how the mentor aids a teacher trainee in developing their competences.  相似文献

Block-pulse functions method of the inverse laplace transform for irrational and transcendental transfer functions     

W. Marszałek 《Journal of The Franklin Institute》1984,318(3):193-200

A new direct method of the block-pulse functions technique of the inverse Laplace transform for irrational and transcendental transfer functions is presented. It is shown that the existing indirect method can be used equivalently with the new one. Two illustrative examples are given.  相似文献   

Validity of Holland’s theory in adolescence: evidence from a Slovak sample     

Martončik  Marcel  Kačmárová  Monika  Hruščová  Eva  Magáčová Žilková  Ivana  Kravcová  Michaela 《International Journal for Educational and Vocational Guidance》2020,20(3):543-565

The underlying calculus assumption of Holland’s theory was tested in two samples of primary school students (N₁ = 400 and N₂ = 250) with an average age of 13.86 and 14.14 years, respectively. Both exploratory and confirmatory multidimensional scaling and Hubert and Arabie’s randomization test of hypothesized order relations were calculated. The circular spatial arrangement of RIASEC types was not confirmed in either of the two samples. The study discusses possible causes of the inappropriateness of using Holland’s model in an adolescent sample.

Social inequity and educational expansion in Slovenia     

Sergej Flere  Miran Lavrič 《Educational studies》2005,31(4):449-464

The study examines the relationship between social inequalities (stratificational, gender and other disparities) and schooling, including academic attainment, longitudinally, in Slovenia. The issue is indicated most clearly at the tertiary education level. The basic finding is the parallel between educational expansion and the diminution of social inequalities as measured by standard parameters. This was particularly evident in the 1990s. Inequalities are measured in terms of gender, parental education and occupation. The impact of parental education proves to be an indicative, observable and longitudinally comparative measure. Parental occupational status is also clearly linked to their children’s scholastic attainment, although there are difficulties in the formation of occupational strata. Further considered is the impact of school reforms over a lengthier period of time; there was not, however, any detectable impact. School and welfare policies, even financing, have little significance. There are clear indications that social disparities at school are continually regenerated, despite the decline established by standard measures. New forms of social disparities appear, through which the privileged ensure the continuation of privilege.  相似文献   

Trying to Include but Supporting Exclusion Instead? Constructing the Roma in Slovak Educational Policies     

Jozef Miškolci  Lucia Kováčová  Martina Kubánová 《欧洲教育》2017,49(1):71-88

Based on a social constructivist theoretical framework, this research study examines how the design of proinclusive educational policies and the general public construct the Roma students and parents in Slovakia. For this purpose, data from two selected educational policies and five focus groups conducted in five regions in Slovakia were analyzed. The findings demonstrate that the Roma are constructed negatively as irresponsible dependents and deviants not valuing education and incapable of making wise decisions about their lives. These findings can be considered relevant for policy formulation processes because proinclusive policies may sabotage their own goals if negative social constructions of a certain societal group are embedded in them.  相似文献   

Environmental literacy of youth movement members – is environmentalism a component of their social activism?     

Daphne Goldman  Sara Pe’er  Bela Yavetz 《Environmental Education Research》2017,23(4):486-514

Youth-movements in Israel are non-formal organizations that educate for social and political involvement and provide a broad platform for youth involvement in the community. This study explored the question: does the social activism of adolescents who both elect for membership in youth movements and a leadership role of instructing younger members also reflect itself in environmentalism? In a survey of 1496 young instructors drawn from 15 official youth movements, findings on environmental literacy variables show youth are only generally knowledgeable about environmental problems; express ‘technical-optimism’ which leads them to limited concern for the environment; show limited recognition of the importance of environmental education, and show limited acknowledgment of the necessity for changes in personal consumerism. Findings also show that environmental issues are not on their mind since they are not a conversation topic with peers or family. Nonetheless, these youth also demonstrate strong self-efficacy to effect change; view themselves as role models for younger members; and express willingness to include environmentally-supportive activities within regular youth movement activities. Their valuing of nature also provides a foundation for building other environmental values. Further analysis shows how these findings can contribute theoretical and practical tools for incorporating sustainability within the youth movement framework, and help realize their potential for promoting sustainability in society.  相似文献
