Preadolescent EFL learners’ self-efficacy expectancies before and after completion of a grammar task: Multivariate analyses of grade level, gender, a…
2020
Learners’ task-specific self-efficacy expectancies have gained increased attention in the EFL context. Across various competence areas they have been demonstrated to substantially affect learners’ motivation, learning approach, and performance. However, certain research gaps still exist – particularly concerning younger learners’ grammar self-efficacy. Furthermore, though conceptually assumed to play an essential role in learners’ self-efficacy formation and calibration accuracy, little is empirically known about task completion effects. The same applies to the role of grade level and gender differences in lower secondary EFL classrooms. Against this background, the present study addressed …
Inter-generational learning of teachers: what and how do teachers learn from older and younger colleagues?
2018
Abstract: This paper examines how and what teachers learn from their older and younger colleagues. Data were gathered from interviews and written reports from 27 Belgian and Finnish teachers. Thematic qualitative analysis was used. The results revealed differences in what teachers learn from older and younger colleagues. Teachers reported learning innovative teaching methods and ICT skills from younger colleagues, whereas practical information, classroom management skills, self-regulation and community building were learned mainly from older colleagues. Attitudes regarding teaching and different ways of being a teacher were learned from both younger and older colleagues alike. Similarities …
Vascular aging in rodent models: contrasting mechanisms driving the female and male vascular senescence
2021
Increasing scientific interest has been directed to sex as a biological and decisive factor on several diseases. Several different mechanisms orchestrate vascular function, as well as vascular dysfunction in cardiovascular and metabolic diseases in males and females. Certain vascular sex differences are present throughout life, while others are more evident before the menopause, suggesting two important and correlated drivers: genetic and hormonal factors. With the increasing life expectancy and aging population, studies on aging-related diseases and aging-related physiological changes have steeply grown and, with them, the use of aging animal models. Mouse and rat models of aging, the most…
Changes in land surface temperatures and NDVI values over Europe between 1982 and 1999
2006
Abstract We used land surface temperature (LST) algorithms and NDVI values to estimate changes in vegetation in the European continent between 1982 and 1999 from the Pathfinder AVHRR Land (PAL) dataset. These two parameters are monitored through HANTS (Harmonic ANalysis of Time Series) software, which allows the simultaneous observation of mean value, first harmonic amplitude and phase behaviors in the same image. These results for each complete year of data show the effect of volcanic aerosols and orbital drift on PAL data. Comparison of time series of HANTS cloud-free time series with the original time series for various land cover proves that this software is useful for LST analysis, alt…
A Comparison of Finnish and United States Franchisee Satisfaction
2004
This paper investigates, using a multi-dimensional model, differences between franchisee satisfaction in Finland and the United States. Comparison of Finnish and American franchisee satisfaction levels is made across eight dimensions of franchisee satisfaction. Data was collected using a postal survey of Quick Service Restaurant (Hamburger) franchisees in Finland and the United States. Results show franchisees in Finland and the United States are overall equally satisfied. Data analysis revealed that for four of the eight dimensions, franchisees in both countries have statistically equal levels of satisfaction. However, for the other four dimensions, a statistical difference exists between …
Binary Patterns in Infinite Binary Words
2002
In this paper we study the set P(w) of binary patterns that can occur in one infinite binary word w, comparing it with the set F(w) of factors of the word. Since the set P(w) can be considered as an extension of the set F(w), we first investigate how large is such extension, by introducing the parameter ?(w) that corresponds to the cardinality of the difference set P(w) \ F(w). Some non trivial results about such parameter are obtained in the case of the Thue-Morse and the Fibonacci words. Since, in most cases, the parameter ?(w) is infinite, we introduce the pattern complexity of w, which corresponds to the complexity of the language P(w). As a main result, we prove that there exist infini…
Testing Independence: A New Approach
2000
In time series analysis and modelling, testing for independence allows us to determine if the estimated model is correctly specified. In this work, we present a very simple method to test for serial independence, based on the two-dimensional embedding vectors (the so-called “2-histories”), and we analyse the power and size of such a procedure against a wide set of linear and nonlinear alternatives.
An order-adaptive compact approximation Taylor method for systems of conservation laws
2021
Abstract We present a new family of high-order shock-capturing finite difference numerical methods for systems of conservation laws. These methods, called Adaptive Compact Approximation Taylor (ACAT) schemes, use centered ( 2 p + 1 ) -point stencils, where p may take values in { 1 , 2 , … , P } according to a new family of smoothness indicators in the stencils. The methods are based on a combination of a robust first order scheme and the Compact Approximate Taylor (CAT) methods of order 2p-order, p = 1 , 2 , … , P so that they are first order accurate near discontinuities and have order 2p in smooth regions, where ( 2 p + 1 ) is the size of the biggest stencil in which large gradients are n…
Simplified thermal analysis of naturally ventilated dwellings
1991
Abstract A simplified comprehensive methodology for thermal comfort prediction in a naturally crossventilated room is described. The methodology mainly consists of the following three steps: • - analysis of the dynamic thermal behaviour of the given room, by means of the admittance procedure; • - evaluation of the air flows rates and their velocities in the room, by means of a new simplified method; • - thermal comfort prediction by means of the Fanger's theory. The results obtained appear satisfactory and the simplified methodology makes itself a useful tool for the identification of appropriate choices at the early stages of the design process, regarding naturally ventilated buildings. Th…
TORSIONAL STRESS CONCENTRATIONS IN SHAFTS: FROM ELECTRICAL ANALOGIES TO NUMERICAL METHODS
2013
This paper presents the historical development of methods used for the study of torsional stresses in shafts. In particular the paper covers both analog methods, in particular those based on electrical analogies proposed since about 1925, and numerical methods, in particular finite difference methods (FDM), finite element methods (FEM) and boundary elements (BEM).
