Practical stability in terms of two measures for fractional order dynamic systems in Caputo's sense with initial time difference     

Muhammed Çi̇çek  Coşkun Yakar  Mustafa Bayram Gücen 《Journal of The Franklin Institute》2014

The initial time difference practical stability in terms of two measures has been investigated for nonlinear fractional differential equations in Caputo's sense and these properties have been unified with Lyapunov-like functions to establish a comparison result.  相似文献

Effects of ‘Environmental Chemistry’ Elective Course Via Technology-Embedded Scientific Inquiry Model on Some Variables     

Muammer Çalik  Tuncay Özsevgeç  Jazlin Ebenezer  Hüseyin Artun  Zeynel Küçük 《Journal of Science Education and Technology》2014,23(3):412-430

The purpose of this study is to examine the effects of ‘environmental chemistry’ elective course via Technology-Embedded Scientific Inquiry (TESI) model on senior science student teachers’ (SSSTs) conceptions of environmental chemistry concepts/issues, attitudes toward chemistry, and technological pedagogical content knowledge (TPACK) levels. Within one group pre-test–post-test design, the study was conducted with 117 SSSTs (68 females and 49 males—aged 21–23 years) enrolled in an ‘environmental chemistry’ elective course in the spring semester of 2011–2012 academic-years. Instruments for data collection comprised of Environmental Chemistry Conceptual Understanding Questionnaire, TPACK survey, and Chemistry Attitudes and Experiences Questionnaire. Significant increases in the SSSTs’ conceptions of environmental chemistry concepts/issues, attitudes toward chemistry, and TPACK levels are attributed to the SSSTs learning how to use the innovative technologies in the contexts of the ‘environmental chemistry’ elective course and teaching practicum. The study implies that the TESI model may serve a useful purpose in experimental science courses that use the innovative technologies. However, to generalize feasibility of the TESI model, it should be evaluated with SSSTs in diverse learning contexts.  相似文献   

On the need to repoliticise environmental and sustainability education: rethinking the postpolitical consensus     

Louise Sund  Johan Öhman 《Environmental Education Research》2014,20(5):639-659

This article draws attention to the possibilities of the ongoing philosophical discussion about cosmopolitan universal values in relation to the normative challenges in environmental and sustainability education (ESE). The purpose of this paper is to clarify the philosophical problems of addressing universally sustainable responsibilities and values in ESE. Our arguments draw inspiration from the work of three poststructuralist scholars: we explore how Butler develops her claim that universal assertion requires a cultural translation, how Mouffe exposes the political in universal claim and how Todd argues that education needs to introduce students to a political language that enables them to critically reflect on their own and other groups’ values and actions. In the concluding part, we suggest the following guidelines for rethinking ESE: unmasking the political dimension, re-politicising education, seeing beyond the relativist and objectivist divide and using passion as a moving force.  相似文献   

Assessment by project work in snow engineering     

ANGELA LUNDBERG  LARS VIKSTRÖM  MARIA VIKLANDER 《European Journal of Engineering Education》2003,28(1):7-16

Assessment in the form of a large project and field- and laboratory work was shown to be successful when applied to a course in snow engineering for university students with various backgrounds. The course was interdisciplinary, with teachers representing three different engineering disciplines. The project work was assessed by a report, a short oral presentation and an optional presentation such as a home page, a poster or a physical model. The students experienced that they had learned more with this assessment strategy than from courses with a final written exam. Peer evaluation of the relative contributions to the project work was applied and was appreciated by the students. The experiences of practical engineering tasks during the project work were also appreciated.  相似文献

Ground level ozone exposure and distribution over the historical Peninsula of Istanbul     

Ferhat Karaca  Zeynep Öztürk 《Journal of Cultural Heritage》2012,13(1):69-76

In this study, passive samplers were used to measure ozone exposure distribution maps over the historical peninsula of Istanbul, Turkey. The study area is partially important due to the presence of cultural and historical buildings and structures distributed all over the peninsula. Unesco's World Heritage list covers four zones located in this historical peninsula in Istanbul. It is necessary to evaluate the pollution distribution in high resolution to construct effective risk management strategies. For this purpose, 50 sampling stations were installed within the study area. Three sampling campaigns within different seasons (summer, winter and fall) showing different ozone distribution characteristics were carried out. Seasonal measurements of ozone exposure values were used to obtain a yearly exposure level, which is an important part of risk characterization. Seasonal ozone exposure maps over the historical peninsula were obtained using Geographical Information Systems (GIS) based interpolation models with high resolution. Risk maps including five regions, based on ozone exposure levels were created. Structures and historical regions located within these risk zones were identified. Based on the defined exposure regions, we found that the Archaeological Park, one of the items on UNESCO's list, is located within the most risky region.  相似文献   

Visual autocorrelation of prices     

Ünsal Özdilek 《Journal of Cultural Economics》2013,37(2):203-223

Paintings are in essence about visual features of varying significance from which differences in their market prices originate. Studies normally investigate derivative sources of painting price determinants, which is reasonably understandable because the appreciation of an image is quite subjective. This paper provides an operational solution to the quantification of paintings based on a new concept termed as “visual autocorrelation” of prices (VAP). Considering the current empirical framework of spatial and temporal autocorrelation of prices, and using data on the paintings of two abstract expressionist artists, empirical results support the coherence of the VAP concept.  相似文献
