Melanin type and concentration determination using inverse model
2011
Abnormality of melanin production causes skin pigmentation disorders. Currently, assessment of treatment efficacy (under Physician's Global Assessment framework) only refers to visual conditions of skin surface and not the condition of the underlying skin layers and pigments. Albeit researches on models and simulations of light interaction with human skin have been reported, none has been specifically developed for pigmentation analysis of melanin types - eumelanin and pheomelanin. Therefore, our research objectives are to develop image analysis of skin pigmentation for classification and quantification of eumelanin and pheomelanin pigment types in human skin. In this research, the model is…
Towards Sustaining Levels of Reflective Learning: How Do Transformational Leadership, Task Interdependence, and Self-Efficacy Shape Teacher Learning …
2015
Whereas cross-sectional research has shown that transformational leadership, task interdependence, and self-efficacy are positively related to teachers’ engagement in reflective learning activities, the causal direction of these relations needs further inquiry. At the same time, individual teacher learning might play a mutual role in strengthening school-level capacity for sustained improvement. Building on previous research, this longitudinal study therefore examines how transformational leadership, task interdependence, self-efficacy, and teachers’ engagement in self-reflection mutually affect each other over time. Questionnaire data gathered on three measurement occasions from 655 Dutch …
Distributed leadership and teacher’ self-efficacy : the case studies of three Chinese schools in Shanghai
2011
This study looks into the distributed leadership and its influence on teachers’ self-efficacy in three Chinese schools in Shanghai. Against the background of the eighth national curriculum reform launched in 2002, the Chinese schools are seeking for the new way to enhance the school-based curriculum. On top of that, the trend of decentralization also encourages the school principals to involve the teachers in the school leadership practice. The relationship between distributed leadership and teachers’ self-efficacy in this study is examined from the angle of principals’ empowerment strategies. A mixed methods approach is applied to collect both qualitative and quantitative data from the thr…
Subject expertise among teacher students of English and Swedish : the ideal language teacher and self-efficacy beliefs
2015
Käsitykset kielen oppimisesta ja opettamisesta ovat muuttuneet kielen rakenteita korostavista näkemyksistä yhä enemmän kommunikatiivisiksi (Abrahamsson 2009). Tämän tutkielman lähtökohtana onkin havainnoida näiden muuttuvien kielikäsitysten heijastumista kielenopettajaopiskelijoiden näkemyksissä selvittämällä, mitä kielitaidon osa-alueita he pitävät kaikista tärkeimpinä. Tutkielma keskittyy toisaalta oppiainekohtaiseen aineenhallintaan, minkä tarkoitus on kartoittaa opiskelijoiden valmiuksia kohdata tulevan työelämän haasteet. Jotta opiskelijoiden sopeutuminen työelämään tapahtuisi mahdollisimman sujuvasti, tulee heidän luonnollisesti hallita opettamansa kieli mahdollisimman hyvin. Kiviniem…
Cognitive skills, self-beliefs and task interest in children with low reading and/or arithmetic fluency
2022
This study examined the identifiability and early cognitive and motivational markers of low reading and arithmetic fluency. Comparisons of these characteristics between Finnish third graders (n = 197) with low fluency in reading, arithmetic, or both revealed, first, that the majority of third graders with low arithmetic fluency showed low arithmetic skills already at first-grade spring, whereas children with low reading fluency were identified from the second-grade fall onward. Second, all groups with low fluency showed low rapid automatized naming and counting skills across the primary school years, while in other cognitive skills these groups showed different patterns. Third, all groups w…
School-based group intervention in attention and executive functions: Intervention response and moderators
2022
ObjectiveThis study investigated the effects of a school-based skill-training intervention in attention control and executive functions for pupils with hyperactivity-impulsivity (H-I) and cognitive control (CC) deficits. The main aim was to examine whether the intervention differently influenced H-I and CC, and whether cognitive abilities or conduct problems moderated response to the intervention.MethodElementary school pupils from 41 schools participated the study and were divided into an intervention group (n = 71) and a waitlist control group (n = 77). Intervention outcomes were assessed with an inventory assessing executive function difficulties (including H-I and CC) completed by class…

Kognitīvie faktori bezdarbnie…
Predicting physical activity change in cancer survivors: an application of the Health Action Process Approach.
2022
Purpose Previous research has not examined the utility of the Health Action Process Approach (HAPA) to predict physical activity (PA) change in cancer survivors. The aim of the study was to investigate the efficacy of a HAPA-based model in predicting temporal change in moderate-to-vigorous physical activity (MVPA) in cancer survivors. Methods Participants enrolled in the Wearable Activity Technology and Action Planning (WATAAP) trial completed validated questionnaires (n = 64) to assess HAPA constructs (action and maintenance self-efficacy, outcome expectancies, action planning, risk perceptions, and intention) and wore an ActiGraph to measure PA at baseline, 12 weeks, and 24 weeks later. D…

Part 2 is more specifically related to examining the predictive ability of fear of failure and self-efficacy on self-handicapping. …
I’m Not Good for Anything and That’s Why I’m Stressed: Analysis of the Effect of Self-Efficacy and Emotional Intelligence on Student Stress Using SEM…
2020
Stress negatively affects the well-being and the quality of life of the society. Specifically in the academic context, it is relevant to analyze its levels due to its impact on performance and learning. There are factors that affect the said stress including, among others, self-efficacy, and emotional intelligence. The purpose of this study is to analyze how emotional intelligence and perceived self-efficacy affect student stress. In order to show this influence, two complementary methodologies are implemented: the structural equation models (SEMs) and the comparative qualitative analysis (QCA). A total of 477 students (85% of women) from a private University of Valencia participated in the…
