Impact of Curling and Warping on Concrete Pavement, TR-668, 2016

Portland cement concrete (PCC) pavement undergoes repeated environmental load-related deflection resulting from temperature and moisture variations across the pavement depth. This phenomenon, referred to as PCC pavement curling and warping, has been known and studied since the mid-1920s. Slab curvature can be further magnified under repeated traffic loads and may ultimately lead to fatigue failures, including top-down and bottom-up transverse, longitudinal, and corner cracking. It is therefore important to measure the “true” degree of curling and warping in PCC pavements, not only for quality control (QC) and quality assurance (QA) purposes, but also to achieve a better understanding of its relationship to long-term pavement performance. In order to better understand the curling and warping behavior of PCC pavements in Iowa and provide recommendations to mitigate curling and warping deflections, field investigations were performed at six existing sites during the late fall of 2015. These sites included PCC pavements with various ages, slab shapes, mix design aspects, and environmental conditions during construction. A stationary light detection and ranging (LiDAR) device was used to scan the slab surfaces. The degree of curling and warping along the longitudinal, transverse, and diagonal directions was calculated for the selected slabs based on the point clouds acquired using LiDAR. The results and findings are correlated to variations in pavement performance, mix design, pavement design, and construction details at each site. Recommendations regarding how to minimize curling and warping are provided based on a literature review and this field study. Some examples of using point cloud data to build three-dimensional (3D) models of the overall curvature of the slab shape are presented to show the feasibility of using this 3D analysis method for curling and warping analysis.

Science-based entrepreneur project development process for pre-service science teachers: difficulties faced*

This study used a phenomenological research design to determine the difficulties faced in the science-based entrepreneur project development process for pre-service science teachers.. Qualitative data were obtained through interviews conducted with ten pre-service science teachers. The data were analysed using an inductive thematic analysis. The results indicated that pre-service science teachers have most difficulty ‘making decisions on one of the innovative ideas’ and ‘making predictions about unexpected situations’. They also have difficulties ‘calculating the cost as a result of design or work analysis’, ‘identifying if the idea already existed (similarity analysis)’ and ‘making decisions on the required materials, tools, services’. These results show the need for pre-service science teachers to communicate with other institutions and organisations.

A guideline to improve qualitative social science publishing in ecology and conservation journals

A rise in qualitative social science manuscripts published in ecology and conservation journals speaks to the growing awareness of the importance of the human dimension in maintaining and improving Earth’s ecosystems. Given the rise in the quantity of qualitative social science research published in ecology and conservation journals, it is worthwhile quantifying the extent to which this research is meeting established criteria for research design, conduct, and interpretation. Through a comprehensive review of this literature, we aimed to gather and assess data on the nature and extent of information presented on research design published qualitative research articles, which could be used to judge research quality. Our review was based on 146 studies from across nine ecology and conservation journals. We reviewed and summarized elements of quality that could be used by reviewers and readers to evaluate qualitative research (dependability, credibility, confirmability, and transferability); assessed the prevalence of these elements in research published in ecology and conservation journals; and explored the implications of sound qualitative research reporting for applying research findings. We found that dependability and credibility were reasonably well reported, albeit poorly evolved in relation to critical aspects of qualitative social science such as methodology and triangulation, including reflexivity. Confirmability was, on average, inadequately accounted for, particularly with respect to researchers’ ontology, epistemology, or philosophical perspective and their choice of methodology. Transferability was often poorly developed in terms of triangulation methods and the suitability of the sample for answering the research question/s. Based on these findings, we provide a guideline that may be used to evaluate qualitative research presented in ecology and conservation journals to help secure the role of qualitative research and its application to decision making.

My Ideal School: A Personal Construct Psychology Approach to Understanding the School Constructs of Children Described as Anxious

This research explores the school constructs of children described as anxious. Little research exists that looks at understanding children’s school-related anxiety through the lens of Personal Construct Psychology (PCP). This qualitative research design includes semi-structured interviews that followed a PCP theoretical framework. The interviews were carried out with five children aged between 7 and 11, who attended state schools in Malta, and who were experiencing school-related anxiety. Participants were asked to comment and produce drawings about the kind of school they would like to attend (their ideal school), and the kind of school they would not like to attend. The children’s constructs were organised according to whether they related to adults in school, their peers, the school and classroom environment, and the participants themselves in each of these two imaginary schools. Participants were also asked to think of how the school they currently attend can become more like their ideal school. Findings indicate the importance of relationships between teachers and pupils, relationships amongst pupils themselves, a positive learning environment within the classroom and the belongingness to a common value system and school ethos to which anxious children can relate. This research aims to shed light on the responsibility of professionals working with children with school-related anxiety to look beyond within-child factors and understand possible stressors in the child’s environment as potentially contributing to heightening their anxiety.

Chefsintroduktion : En kvalitativ studie om nytillträdda chefers upplevelse av introduktionen till arbetet

Syftet med studien är att skapa en djupare förståelse för hur introduktionen upplevs av nytillträdda chefer samt vilka aspekter som är av betydande relevans för denna upplevelse. Studien har genomförts på en svensk myndighet med omkring 1200 anställda. Studien är av kvalitativ art och empiri har inhämtats genom semistrukturerade intervjuer med åtta verksamma chefer som har personalansvar. Vid tolkning av studiens resultat har vi inspirerats av en fenomenologisk ansats, varpå vi har fokuserat på likheter i respondenternas uppfattning av fenomenet. Av studiens resultat framgår att majoriteten av cheferna upplevt introduktionen som gedigen och informativ. Chefernas framträdande upplevelse har visat sig vara organisationens välkomnande klimat. Majoriteten av cheferna är av åsikten att organisationen möjliggjort för socialisationstillfällen i samband med introduktionen. Flertalet av cheferna föredrar att först installera sig i sin arbetsgrupp innan hela verksamhetsförståelsen kan erhållas. Avslutningsvis har den information som delgivits under introduktionen upplevts som tydlig. Ett flertal av cheferna har samtidigt upplevt den som överväldigande och svåråtkomlig.

Intellectual Capital Disclosures: The effect of mandatory Integrated Reporting

Purpose – The purpose of this thesis is to investigate how mandatory obligation to follow the International <IR> Framework while producing the corporate reports influence the intellectual capital disclosures in the reports. Research design – The study uses a disclosure scoreboard to score a selected sample of annual reports depending on whether it disclose intellectual capital information or not. The sample consists of companies listed in South Africa were it is mandatory to follow the integrated reporting framework and companies listen in Sweden where it is not mandatory to produce an integrated report. Empirical results and conclusion – The results of this thesis indicates that the mandatory use of the International <IR> Framework have an impact on the amount of intellectual capital disclosures. Further it concludes that higher level of compliance with the framework further increases the intellectual capital disclosure. Contribution – This study has been an early step towards concluding whether the use of integrated reporting has any effect on the amount of intellectual capital information disclosed in companies’ annual report.

Comply-or-explain in Sweden : A study on the quality of non-compliance explanations

Purpose: The purpose of this study is to examine the effectiveness of the comply-or-explain principle in Sweden to determine if the flexible approach is functioning as in-tended. Research design: This paper scrutinizes the quality of the explanations with respect to the Swedish Corporate Governance Code. A quantitative research with a cross-sectional design has been performed and the data collection covers 241 companies listed on Nasdaq OMX Stockholm for the fiscal year of 2014. The secondary data has been gathered from corporate governance reports of the researched companies and analysed by using a tax-onomy of explanations. Findings: The report demonstrates that the comply-or-explain principle in Sweden is effective. A clear majority of the explanations, 71,8%, were deemed as informative, mean-ing that a large proportion of the Swedish firms are utilizing the flexible approach in an effective manner. However, one out of four explanations were classified as insufficient and we have thus provided recommendations in order for the code to become even more effective. Contribution: Our findings provide insights on how the comply-or-explain principle works in a country that is supposed to be a leading example of how the comply-or-explain approach should be implemented. This study should be of significance for policy makers considering that we have outlined how the principle works and provided recommenda-tions on how the Swedish Corporate Governance Code can be improved. Value: Our findings demonstrate that companies listed on Nasdaq OMX Stockholm pro-vide high quality explanations that can serve as an inspiration for companies listed in other countries. Furthermore, the results indicate that managers are likely to act within ethically desired norm. Considering the social implications, as Swedish firms are informative in terms of explanations, it minimizes the risk of firms acting dishonestly.

European student mobility and intercultural learning at a portuguese university

The purpose of this study is to understand, impact and evaluate the development of intercultural communicative competencies among European credit-seeking exchange students and other sojourners through purposeful intercultural pedagogy. This pedagogy encompasses intentional intercultural- educational approaches which aim to support and enhance sojourners’ intercultural learning throughout the study abroad cycle (pre-departure, in-country and reentry phases). To test and validate these pedagogies a 20-hour intervention was designed and implemented among two cohorts of 31 sojourners during the in-country phase of their sojourn in Portugal. The process to develop and validate the intercultural intervention was driven by a mixed-methods methodology which combined quantitative and qualitative data to triangulate, complement and expand research results from a pragmatic stance. The mixed methods research design adopted is multi-phased and encompasses a multi-case study and an evaluative component. The multi-case component is embodied by sojourner cohorts: (1) the primary case study involves 19 incoming students at the University of Aveiro (Portugal) as participants in the European exchange program Campus Europae; (2) the second case study comprises three incoming Erasmus students and nine highly skilled immigrants at the same university. All 31 sojourners attended two intermediate Portuguese as Foreign Language classrooms where the intervention was employed. Data collection was extensive and involved collecting, analyzing and mixing quantitative and qualitative strands across four research phases. These phases refer to the: (1) development, (2) implementation and (3) evaluation of the intervention, as well as to (4) a stakeholder analysis of the external value of the intervention and of the Campus Europae program. Data collection instruments included pre and posttest questionnaires and semi-structured interviews. Results confirm the intercultural effectiveness of the intervention and the positive impact upon research participants’ intercultural gains. This impact was, however, greater in case study 2. Among explanatory variables, three stand out: (1) participant meaning-making abilities, (2) host language proficiency and related variables, and (3) type of sojourn or exchange programs. Implications for further research highlight the need to systematize purposeful intercultural pedagogy in sojourner populations in general, and in European credit student mobility in particular. In the latter case, these pedagogies should be part of the design and delivery of credit-bearing exchange programs in pre- departure, in-country and re-entry phases. Implications for practice point to the urge to improve intercultural practices in: macro (higher education institutions), mezzo (exchange programs) and micro (sojourner language classrooms) contexts where this research took place, and wider social scenarios they represent.

Credible or not : A study on the factors influencing consumers' credibility assessment of product placements on Instagram

Background: To align with the new trend of using social media in the marketing mix, product placement has been adapted to social media platforms as one strategy to create attention. Especially on Instagram, product placements have gained popularity among companies. While scholars have focused on measuring the effectiveness of the strategy, suggesting that credibility is one component necessary for success, a gap in the research is illuminated when focusing on what makes a product placement on Instagram credible. Previous studies regarding credibility and its relation to traditional media have concluded that there are some factors essential in consumers’ credibility evaluation process. Since social media differs from traditional media, there was a need to investigate the applicability of credibility to the social media platform Instagram. Purpose: The purpose of this thesis was to examine key factors of product placement on Instagram that influence credibility. Method: To meet the purpose of this thesis a study with a mixed method research design was conducted. The qualitative data was collected through semi-structured interviews with the intention to discover how consumers evaluate credibility. The scales and items developed from the findings of the qualitative study were tested using a questionnaire to identify which factors that have the most influence on consumers’ credibility assessment. Conclusions: The overall findings indicate that consumers evaluate credibility based upon source, message and receiver characteristics. The empirical evidence suggests that the Expertise of influencer, Professionalism of picture, Trustworthiness of influencer, Connection to influencer and Causes of irritation are the factors that have the most influence on consumers’ credibility assessment of product placement on Instagram. The findings further implies that it is not only the factor itself that influence, credibility can additionally be transferred from one factor to another.

Management of Customer Co-development in Business-to-Business Markets

Management of customer co-development means involving customers in the development of new products and services, and coordinating the process. In business-tobusiness markets, customer co-development enables the development of innovations that better match customer needs and strengthens customer relationships. However, close collaboration with customers can hamper the innovativeness of new products and lead to overly customized solutions. Therefore, the management of co-development is crucial to its success. Yet the existing research on management of co-development has mainly focused on selecting the right collaboration partners, and the field lacks understanding on how to manage the tensions inherent in customer co-development. The purpose of this thesis is to increase understanding on the management of the codevelopment. The thesis is divided into two parts. The first comprises the literature review and conclusions for the whole study, and the second presents four publications. From the methodological perspective, the research papers follow exploratory qualitative research design. The empirical data comprise interviews with 60 persons, representing 25 different organizations, and a group of 11 end users. The study conceptualizes management of customer co-development in three dimensions 1) relational co-development processes, 2) co-development challenges and paradoxes, and 3) internal customer involvement processes. The findings contribute to the customersupplier relationship, innovation, and marketing management literatures by providing a framework on supplier-customer co-development, addressing co-development paradoxes and their management processes, and suggesting practices for customer involvement. For practitioners, the findings provide tools to manage the challenges related to codevelopment with customers.
