Psychometric Aspects of the Depressive Experiences Questionnaire: Implications for Clinical Assessment and Research
2018
The Depressive Experiences Questionnaire (DEQ) is a self-report measure that assesses self-criticism and dependency, 2 personality traits that confer vulnerability to depression (Blatt, 2004). Over several decades, different, shortened versions of the DEQ have been constructed to offer an alternative to the complex scoring procedure of the original DEQ. This study explores the factor structure as well as the construct and convergent validity of the DEQ by comparing a clinical and nonclinical sample. We also compared the original DEQ with 5 shortened versions. There were 621 participants (358 university students and 263 outpatients). Fit indexes for models of the original DEQ did not meet mi…
TQM Application through Self-Assessment and Learning: Some Experiences from Two EQA Applicants
2006
[This abstract is based on the author's abstract.]The introduction of international quality awards has increased the importance of self-assessment in the implementation of total quality management initiatives. Models underlying these awards stress the p..
Willingness to Communicate in L2 and Self-Perceived Levels of FL Skills in Polish Adolescents
2011
The willingness to communicate (WTC) construct, originally referring to individuals’ tendencies to engage in communication in the L1 when given the free choice (McCroskey and Richmond, Personality and interpersonal communication, Newbury Park, CA, pp. 129–156, 1987), can also be applied to a second language context (MacIntyre, Dornyei, Clement and Noels, Mod Lang J 82:545–562, 1998). It can then be defined as “a readiness to enter into discourse at a particular time with a specific person or persons, using a L2” (MacIntyre, Dornyei, Clement and Noels, Mod Lang J 82:545–562, 1998, p. 547). MacIntyre, Dornyei, Clement and Noels, (Mod Lang J 82:545–562, 1998) proposed a pyramid-shaped L2 WTC m…
Rasch Analysis of the Japanese Version of Teacher Efficacy for Inclusive Practices Scale: Scale Unidimensionality
2020
This study aimed to examine the construct validity of the Japanese version of the Teacher Efficacy for Inclusive Practices (TEIP) scale. The sample consisted of 250 teachers in Japan. Rasch analysis was used to examine the psychometric properties of the scale. Results did not support the 18-item Japanese version of the TEIP scale as a unidimensional scale for measuring TEIP. However, they do support the final 14-item Japanese version of the TEIP scale as a unidimensional scale for measuring TEIP. Four items were removed from the original 18-item scale (items 12, 8, 5, and 3) for violation of the local independency assumption. No item with differential item functioning (DIF) was detected. On…
Order Parameters for Self-Organizing Maps
1998
We introduce and discuss different approaches to construct order parameters for Kohonen’s Self-Organizing Maps. As one approach the notion of an order parameter in the sense of Haken’s synergetics is studied and contrasted with organization measures using SOM structure information.
Tree Structured Self-Organizing Maps
1999
Publisher Summary This chapter provides an overview of the tree structured self-organizing maps (TS-SOM). It was originally intended as a fast implementation of the self-organizing map (SOM). The chapter explains that TS-SOM is a constructive smoother for a class of dimension reduction problems. There is a well known relation between self-organizing maps and principal curves. Unfortunately in most presentations it is derived by simple reasoning, avoiding the mathematical statement of the problem, which is essential to understand how efficient SOM implementations can be constructed. In this chapter, SOM is derived as a numerical solution of a generic model in a continuous domain, which diffe…
Measurement of the forward-backward asymmetry of e(+)e(-)-]z-]b(b)over-bar using prompt leptons and a lifetime tag
1995
The forward-backward asymmetry of the process e+e-→Z→b {Mathematical expression} has been measured using events collected by the DELPHI experiment during the 1991 and 1992 LEP runs. This data sample corresponded to 884 000 hadronic Z decays at a centre-of-mass energy {Mathematical expression}. The tagging of b-quark events was performed using two approaches; the first was based on the semileptonic decay channels b→X+μ and b→X+e, the second used a lifetime tag with jet-charge reconstruction. The results of these two methods were combined to give {Mathematical expression} With the semileptonic sample, the forward-backward asymmetry of the process e+e-→Z→ {Mathematical expression} was also mea…
Drawings, Gestures and Discourses: A Case Study with Kindergarten Students Discovering Lego Bricks
2020
This paper presents a study aimed at investigating the didactic potentiality of the use of an artefact, useful to construct mathematical meanings concerning the coordination of different points of view, in the observation of a real object/toy. In our view, the process of meaning construction can be fostered by the use of adequate artefacts, but it requires a teaching/learning model, which explicitly takes care of the evolution of meanings, from those personal, emerging through the activities, to the mathematical ones, aims of the teaching intervention. The main hypothesis of this study is that the alternation between different semiotic systems, graphical system, verbal system and system of …
Approximation Properties of the Modified Stancu Operators
2017
ABSTRACTIn this article we construct a sequence of Stancu-type operators that are based on a function τ. This function is any function on [0,1] continuously differentiable ∞ times, such that τ(0) =...
The Structure and Formation of Customer value in B-to-B Services
2017
This study investigates the hierarchical construct and the formation of customer value of b-to-b services. In-depth understanding of the construction of customer value and the effects of service quality on customer value are the key to effective development of b-to-b services. This quantitative study was conducted through the structured interview method among Finnish business organizations in early 2009. The data consisted of 90 qualified questionnaires. The customer value of b-to-b services was found to be composed of attribute and consequence levels. The dimensions of service quality influenced to differing degrees the formation of the attribute and consequence levels of the customer valu…
