Hidden Markov Random Fields and Direct Search Methods for Medical Image Segmentation

2016

The goal of image segmentation is to simplify the representation of an image to items meaningful and easier to analyze. Medical image segmentation is one of the fundamental problems in image processing field. It aims to provide a crucial decision support to physicians. There is no one way to perform the segmentation. There are several methods based on HMRF. Hidden Markov Random Fields (HMRF) constitute an elegant way to model the problem of segmentation. This modelling leads to the minimization of an energy function. In this paper we investigate direct search methods that are Nelder-Mead and Torczon methods to solve this optimization problem. The quality of segmentation is evaluated on grou…

Relationships between core self-evaluation, leader empowering behavior, and job security among Jordan University Hospital nurses

2021

Nurses are facing real stressors due to patients’ needs and leaders’ demands. The aim of this study is to explore the perceived level of core self-evaluation (CSE), leader empowering behavior (LEB), and job security among Jordan University Hospital nurses in Amman, the capital of Jordan. Furthermore, it investigates the relationship between the selected variables. Differences of gender, educational level, experience, and site of work are also examined with job security. Moreover, it evaluates the contribution of CSE, LEB, gender, educational level, experience, and site of work in predicting job security among Jordan University Hospital nurses. A descriptive cross-sectional design was adopte…

Protocol: Literature review on the psychometric properties of the short versions of the scales of social desirability in the answers to competency se…

2018

[EN] Research in business organization in general and talent management (in university or professional students) uses in many cases self-administered questionnaires as a source of data to assess people's competencies. In clinical psychology, it has been shown that self-evaluations of behaviors may present a bias of social desirability. However, even in this field of research it is not usual to measure its effect when taking data. Our work proposes a protocol to find a set of scales of social desirability (SD) with less than 20 items that are valid and reliable. We also intend to identify if SD scales are associated with the self-assessments of some transversal competences.

Development of the insight scale for affective disorders (ISAD): modification from the scale to assess unawareness of mental disorder.

2011

Abstract Background Research on insight in patients with mood disorders has grown in recent years. Several instruments to assess insight have been used, but most of them have been specifically designed for psychosis and may not appear relevant to mood disorders. The aim of the present study is to develop a short, multidimensional, reliable and valid scale to measure insight in patients with mood disorders, based on the Amador's Scale to Assess Unawareness of Mental Disorders (SUMD). Method A Delphi method was used to facilitate expert participation and ensure face and content validity. The SUMD structure and items were used as a reference in the scale development. A new scale with 17 items …

An analysis of English teachers’ self-efficacy in relation to SEN and disability and its implications in a changing SEN policy context

2016

AbstractPolicy and practice in relation to meeting the diverse needs of all children, including those with special educational needs (SEN) and disabilities, is in a state of change in the UK. As a result, there is growing interest in and understanding of the need to focus on factors which impact on teachers’ levels of self-efficacy in meeting the needs of learners with SEN, and the implications of this for further development and training. The research reported in this paper gathered data from teachers at a unique time in the transition of policy and practice in England. Through a quantitative analysis of a questionnaire completed by 213 teachers from a variety of teaching settings, data re…

CLIL modules and their affective impact on students with high English anxiety and low self-efficacy

2019

Many studies in recent years focused on the efficiency of bilingual education in different school settings. If a school pursues a regular implementation of CLIL modules instead of the establishment of proper CLIL streams, the student group that is affected by this teaching approach is much more diverse when compared to the preselected CLIL stream groups. In this regard, also students with high English anxiety and low self-efficacy will have to participate in the modules and it is particularly interesting to see how these student types deal with teaching units held in a foreign language. The study at hand presents results from an intervention at German schools with two biology units taught i…

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…

Selected psychometric aspects of the Polish version of the Liverpool Self-efficacy Scale

2020

BackgroundSelf-efficacy expresses the individual’s belief in their ability to take up and continue actions in order to achieve a particular result and cope with various life events. For people with multiple sclerosis (MS), self-efficacy is an im-portant resource because it affects how they adapt to the disease, and influences their motivation, health-related behavior and physical activity. It also has a great impact on their quality of life. Because of the lack of tools for meas-uring self-efficacy in Polish patients with multiple sclerosis, the goal of the current study was to develop a Polish language version of the Liverpool Self-efficacy Scale (LSES) and assess its validity and reliabil…
