Experimental Investigation on Stiffness and Strength of Single-Lap Z-Pinned Joints in a Laminated CFRP Stress-Ribbon Strip

2016

Carbon fiber-reinforced polymer (carbon-polymer) is an advanced lightweight composite material with high strength and excellent resistance to corrosion and fatigue. Over the past decades, application of fiber-reinforced polymers has been spread from the aerospace to other branches of industry such as automobile and civil engineering. Unidirectional carbon-polymers have a high potential for replacing steel in tensile members. Recently, the first carbonpolymer stress-ribbon bridge has been constructed in Germany. The non-laminated strip-loop carbon-polymer thin strips were used as the load bearing components in this bridge. In comparison with the laminated components, the applied cables are c…

Advances in the endoscopic management of malignant biliary obstruction

2020

Biliary obstruction is common in pancreatobiliary malignancies and has a negative impact on the patient’s quality of life, postoperative complications, and survival rates. Particularly in the last decade, there has been enormous progress regarding the diagnostic and therapeutic options in patients with malignant biliary obstruction. Endoscopy has given a new insight in this direction and novel techniques have been developed for the better characterization and treatment of malignant strictures. We herein summarize the available data on the different endoscopic techniques, and clarify their role in the diagnosis and treatment of malignant biliary obstructive disease. Finally, we propose an al…

Past, present, and future of green product innovation

2021

Firms are under constant pressure from various governmental and nongovernmental agencies to switch from conventional environmentally polluting products to green product innovations (GPIs). However, the relevant research pertaining to GPI has been published in a diverse set of journals that vary in their scope and readership and, therefore, the scholarly contribution to the topic remains largely fragmented. This study has utilised a systematic literature review approach to examine the literary corpus on GPI to paint a holistic picture of its different aspects. The content and thematic analysis of 85 studies resulted in the extraction of seven key research themes: organisational capabilities,…

STUDENT GRAPHICAL INFORMATION LITERACY IN MATHEMATICS AND SCIENCE

2017

Among the most important 21st century skills that every student needs are the ability to work with information. The key for implementing competency based approach to learning will be related to how students' ability to apply skills acquired in, for example, mathematics can be transferred to other subject contexts. Newest OECD PISA results presented in 2016 show a recurring tendency that in Latvia there is a small number of students whose performance is in accordance to the 5th and 6th level of the framework. These two levels represent students' ability to apply deep thinking skills in new learning contexts. It is necessary to analyze the causes of this situation in order to identify opportu…

Aim. The aim of the study is to find out students’ perspectives on the necessity, readiness and disturbing factors of implementing musical activities in preschool. The theoretical part of the paper describes the particularity of preschool teachers’ work, the children’s interest in musical activities, and the benefits of implementing musical activities in preschool. 
 Method. The empirical study involved 168 students (N=168), of which 132 students (N=132) are already working as preschool teachers in parallel with their study at the university. The study identified three questions: why do preschool teachers use musical activities? What factors prevent a preschool teacher from using music…

Gender and entrepreneurial intentions

2014

Author's version of a chapter in the book: L. Kelley (Ed.), Entrepreneurial women : new management and leadership models. The paper identifies commonalities and differences between women and men in terms of eleven key factors’ impact on the formation of entrepreneurial intentions (EIs) among Norwegian students. The analysis is based on a sample of 1,782 Norwegian students from a variety of faculties and degree programs. A path analysis methodological approach is used, while being based on multiple regressions so as to gradually refine model complexities. Findings show that common to both sexes are the effects of entrepreneurial experience, social norms, self-efficacy, and age. The direct ef…

Effects of contextual variables on strategic investment decision-making styles: An empirical study from Pakistan.

2022

There is a gap in the literature of strategic investment decision making (SIDM) concerning the links between context variables, infrastructure and SIDM practices (or SIDM styles) in developing countries. This research aims to fill that gap. Survey data (N = 128) from the manufacturing companies listed on the Pakistan Stock Exchange was collected via an e-mailed questionnaire and visits to the companies. Data are analyzed with factor analysis and multiple regression analysis. The results reveal what we call four different SIDM styles (or emphases): managerial power-, financial analysis-, top management-, and strategy-based investing. These styles are considered to be novel perspectives on SI…

Child Well-Being in Times of Confinement: The Impact of Dialogic Literary Gatherings Transferred to Homes

2020

The COVID-19 pandemic has created an unexpected situation that has forced people to find educational alternatives to support learning and ensure child well-being. The need for practices that 'open doors' at home as a way to promote a quality education and to foster an environment of supportive relationships and a sense of community, has led to the in-depth analysis of successful educational actions, particularly the Dialogic Literary Gatherings (DLGs). The aim of this article is to show how the transference of DLGs to the home environment has had an impact on child subjective well-being in times of confinement, promoting a safe and supportive environment for learning, interacting, coexistin…
