Investigation of newly developed added damping and stiffness device with low yield strength steel

Energy dissipators, isolated-resistant and specific structural forms for earthquake resistance are popular topics in the research to improve shock-resistance. In this work, experimental methods were used to investigate the property of low yield strength steel. Carbon content in LYS material is lower than that in other steels; the ultimate stress is three times the yield stress. The ultimate elongation rate is about 62% and the ductility is 2–3 times that of A36 steel. In order to overcome some defects of ordinary use metallic dampers, the mechanical characteristic of low yield strength steel is used to develop added damping and stiffness for rhombic steel plate absorber. Test of the energy dissipation behavior for this newly developed device indicated that LYS could stably dissipate or absorb the input energy of earthquake. Then, the analytical model for the hysteretic behavior of this new device is proposed. Comparison of experimental data and numerical simulation results showed that this analytical model is suitable for simulating the hysteretic energy behavior of this new device.     

Re-situation challenges for international students ‘becoming’ researchers

This paper presents data generated during a semester-long programme to support international students from countries in Melanesia and Asia embarking on masters research in education in a New Zealand university. All were scholarship recipients. The researcher-and facilitator-of the programme, was interested in documenting and understanding the nature of the students’ experience as they planned and wrote research proposals. The process of developing a research proposal, as one of the early stages of ‘becoming’ a researcher, highlighted a number of challenges for the six case study students. The challenges are viewed from a transition or ‘resituation’ perspective (Eraut in Stud Contin Educ 26(2): 247–74, 2004, 2008) rather than an adjustment one. A resituation perspective assumes that students brought with them “personal expertise, practical wisdom and tacit knowledge” (Eraut 2008, p. 42) which needed to be reconciled with what was demanded of them by different aspects of the research planning process. The resituation challenges experienced by the students included situating a perceived problem or issue in the research literature; reconciling personal research goals with the limitations of one’s own agency as a researcher; integrating new learning with research goals; and reconciling the new role or identity as a researcher with the previous role as colleague or community member. The paper presents a case for providing a context for postgraduate students in which explicit recognition of what they bring to the research task, and acknowledgement of the resituation challenges can take place.     

Relations between teacher students’ approaches to learning,cognitive and attributional strategies,well-being,and study success

Current theories of learning emphasize the role of motivational and affective aspects in university student learning. The aim of the present study was to examine the interrelations among approaches to learning, self-regulated learning, and cognitive strategies in the context of teacher education. Cognitive-motivational profiles were identified among novice teacher students. It was also looked at, whether well-being, epistemological beliefs, and study success in an activating lecture course were related to these profiles. The participants were 213 first year teacher students, who participated in an activating lecture course at a major Finnish university. The students filled in a questionnaire including items based on the MED NORD instrument (Lonka et al. in Med Teach 30:72–79, 2008). The structural validity of the scales was tested by means of a series of factor analyses. Latent class clustering was used for clustering students into homogeneous groups. Finally, a series of ANOVAs was conducted to examine between-group differences across the criterion variables. Three groups of students were identified (1) non-regulating students (50%), (2) self-directed students (28%), and (3) non-reflective students (22%). Non-regulating students expressed the highest levels of stress, exhaustion, and Lack of Interest. Self-directed students received the highest grades. The profiles were not only related to study success, but also to the general well-being of the students. It was concluded that motivational profiles may have not been optimal, even in this highly-selected population. It is of interest to see, how these students shall develop during their studies.     

Signifying the accumulation graph in a dynamic and multi-representation environment

The present study focuses on the accumulation process involved in the integration of a single-variable function. Observing the work of two high-school calculus students who had not yet learned any other integral-related ideas, we analyze the emergence of the semiotic relationship between personal and mathematical meanings, as expressed through the understanding of mathematical signs in integration tasks. Adopting Radford's educational perspective whereby learning is defined as a process of objectification, we identify a three-stage evolution of the double semiotic meaning of the lower boundary and of its role in the definition of the accumulation graph: (1) objectifying a zero accumulation in relation to the lower limit, (2) objectifying zero as marking the zero sum of accumulated areas, and (3) objectifying the accumulation graph as dependent on the lower-limit value. This evolution is marked by semiotic changes related to the pivotal role of the “zeros” in the accumulation graph.     

Reading the water table: The interaction between literacy practices and groundwater management training in preparing farmers for climate change in South India

This article focuses on farmers’ use of literacy for individual decision-making on crop-water management and crop choices and investigates how farmer participants perceive the usefulness of Farmer Water School (FWS) training. It draws upon a study conducted with farmers of Kurnool district of Andhra Pradesh, India. This study has demonstrated that literacy skills, while valued, are not a prerequisite for all farmers to improve their groundwater and crop management, as long as training includes (1) the presence of at least some literate farmers, (2) activities that involve learning by doing, and (3) learning in small mixed groups of literate and non-literate participants. The study outcomes are of increasing relevance in the context of climate change and variability, as small and marginal farmers constitute over 87 per cent of Indian farmers. Their inability to cope with consequences of climate change could adversely affect the food security in the country.     

Benchmarking citation measures among the Australian education professoriate

Individual researchers and the organisations for which they work are interested in comparative measures of research performance for a variety of purposes. Such comparisons are facilitated by quantifiable measures that are easily obtained and offer convenience and a sense of objectivity. One popular measure is the journal impact factor, based on citation rates, but it is a measure intended for journals rather than individuals. Moreover, educational research publications are not well represented in the databases most widely used for calculation of citation measures, leading to doubts about the usefulness of such measures in education. Newer measures and data sources offer alternatives that provide wider representation of education research. However, research has shown that citation rates vary according to discipline and that valid comparisons depend upon the availability of discipline-specific benchmarks. This study sought to provide such benchmarks for Australian educational researchers based on analysis of citation measures obtained for the Australian education professoriate.     

Teaching and Learning Science in Hungary, 1867–1945: Schools,Personalities, Influences

The article provides an overview of the development of teaching science in Hungary during both the time of the dual monarchy and the newly established independent Hungary after 1920. The integration of Hungary into the Austro-Hungarian Monarchy (1867–1918) strengthened the effect of German speaking European science, the results of which were quickly channelled into the Hungarian school system at all levels. The Hungarian Academy as well as the University of Budapest (today Eötvös Loránd University) played a leading role in the ?nationalization” of European science in the educational system. Scientific developments in Hungary strengthened the position of rational and secular thinking in a highly religious society and contributed to the erosion of the mental power of the church tradition, particularly that of the Roman Catholic Church. Toward World War I, influenced by the Protestant Churches, the Jewish tradition, and agnosticism, the public picture of science became more international, occasionally ready to consider challenges of the accepted world view, and sometimes less dogmatic. Leading Hungarian figures with an international reputation who played a decisive role in making science part of Hungarian thinking included the physicists Baron Loránd Eötvös and Sándor Mikola, the mathematicians László Rácz and George Pólya as well as a host of others in related fields. Emigration, mostly Jewish, after World War I, contributed to the curtailment of efforts to teach science effectively as some of the best people left Hungary for, mostly, Germany, Britain, and the United States. However, the interwar school system, the Hungarian version of the German Gymnasium, continued to disseminate scientific thought in Hungarian education. Much of the information was foreign and appeared simply in translation—but an impressive array of indigeneous scientific results paved the way to a larger educated middle class then in the making.
