Controversy, as a vital principle of democracy, plays a central role in education for critical democratic global citizenship. Controversial issues, however, raise pedagogical challenges for teachers in that they are not only explicitly political, but also potentially threatening to the reproduction of status quo ideals and embedded national narratives – themselves keystones of citizenship education. The findings from this dissertation study report survey data on teachers’ attitudes toward teaching controversial issues from 202 Canadian teachers, as well as findings from interviews conducted with 16 Alberta teachers about how their multiple identities, and those of their students, intersect with their attitudes toward teaching controversial issues. The findings are discussed against indicators of critical democratic global citizenship education (CDGCE) which I advance in the thesis following from my investigation into the relationship between critical theory of a) democracy, b) globalization, and c) education. I engage the findings through the lens of critique and possibility and the reproduction and interruption of hegemonic discourse. Read through this lens, I found that hegemonic discourses of neutrality and universalism are being both reproduced and interrupted in complex ways that do affirm, but mostly refute, the promise of education for deepening democracy under conditions of globalization. Discourses of neutrality and universalism are being reproduced through insidious practices that affirm difference-blind and blank slate ideals and these need responding to. These have implications for how students in Canadian classrooms may be being prepared for critical democratic global citizenship education. Despite the misguided emphasis on the danger of teachers’ expressing extreme views in dominant discourses of education that question the place of controversial issues in school, I argue that the greater threat to deepening democracy is not teachers who express extreme views; it is curriculum and teachers who do not question familiar ones. In turn, I call for critical discursive and reflexive practices for teaching and learning with controversial issues that foreground identity, difference, and feelings as explicit material for learning. Finally, I delineate specific recommendations that are crucial responses for realizing the promise of education for deepening democracy under conditions of globalization.

Objectives: 1. To determine the proportion of people reporting time loss from work, school, or normal activities due to oral health issues. 2. To determine how much time is being lost. 3. To establish predictors of this time loss. 4. To determine the productivity losses. Methods: Data from the Canadian Health Measures Survey (2007-2009) were used. Linear and logistic regressions were employed to determine which variables were predictive of hours lost and reporting time loss. Productivity losses were determined using the lost wages approach. Results: Time loss is more likely among privately insured, high income earners. Experiencing oral pain is the best predictor of reporting time loss. Productivity losses are comparable to those of some musculoskeletal conditions. Conclusions: Participants with higher incomes report time loss more frequently while the total amount of time lost is greatest for those with the lowest incomes. Productivity losses are substantial at the societal level.

We study the eff ects of stochastic volatility of defaultable bonds using the first -passage structural approach. In this approach Black and Cox (1976) argued that default can happen at any time. This then led to the development of afirst-passage model, in which a rm (company) default occurs when its value falls to a barrier. In the first-passage model the rm debt is considered to be a single pure discount bond and default occurs only if the rm value falls below the face value of the bond at maturity. Here the firm's debt can be viewed as a portfolio composed of a risk-free bond and a short-put option on the value of a rm. The classic Black-Scholes-Merton model only considers a single liability and the solvency is tested at the maturity date, while the extended Black-Scholes-Merton model allows for default at any time before maturity to cater for more complex capital structures and was delivered by Geske, Black-Cox, Leland, Leland and Toft and others. In this work a review of the eff ect of stochastic volatility on defaultable bonds is given. In addition a study from the first-passage structural approach and reduced-form approach is made. We also introduce symmetry analysis to study some of the equations that appear in option-pricing models. This approach is quite recent and has produced successful results. In this work we lay the foundation of this method. Keywords: Stochastic Volatility, Defaultable bonds, Lie Symmetries. / Thesis (M.Sc.)-University of KwaZulu-Natal, Westville, 2009.

Naturvetenskap är en viktig kunskap att besitta för alla i ett samhälle. Inte minst för att förstå och förhålla sig kritisk mot mycket av den information som vi möts av dagligen genom media. De val vi gör påverkar oss som individer både lokalt och globalt, inte bara idag utan även framåt. Trots ämnets betydelse för samhället är många elever allt mindre intresserade av naturkunskap i skolan. Deras brist på intresse för naturvetenskap har visat sig genom flera internationella studier där studieresultaten så väl som attityden gentemot ämnet försämrats. Den här systematiska litteraturstudien syftar därför till att belysa det faktum att naturkunskapsundervisningen är i behov av en förändring för att vända den här negativa trenden. Studien syftar även att undersöka hur naturkunskapsundervisningen kan utvecklas genom en relativt ny undervisningsmetod. Denna undervisningsmetod lyfter sociovetenskapliga frågor där eleverna får utreda aktuella händelser eller problem genom att angripa det inte bara naturvetenskapligt utan även bland annat etiskt och socialt. Flera forskningsresultat visar att detta är ett arbetssätt som ger positiva effekter på elevers förståelse och engagemang i ämnet. Ytterligare forskning behövs inom ämnet, särskilt med fokus på grundskolan, för att anpassa arbetsmetoden för alla åldrar.

This thesis focuses on upper secondary students’ use of resources in their supporting reasons when arguing socioscientific issues (SSIs). The skills of argumentation have been emphasized in science education during the past decades and SSIs are proven a good context for learners to enhance skills of argumentation and achieve the goal of scientific literacy. Research has shown that supporting reasons from various resources are embedded in students’ argumentation on SSIs, and also that multi-perspective involvement in reasoning is important for the quality of argumentation. To explore the reasons used by students in arguing about SSIs in this thesis, the SEE-SEP model was adopted as an analytical framework. The SEE-SEP model covers the six subject areas of sociology/culture, economy, environment/ecology, science, ethics/morality and policy, which are connected to the three aspects of knowledge, value and personal experience. Two studies covering four SSIs (global warming, GMO, nuclear power and consumption) explore how students construct arguments on one SSI topic chosen by them. In paper I, I investigated students’ use of resources in their informal argumentation and to what extent students made use of knowledge. The results showed that students used value to a larger extent (67%) than knowledge (27%). I also found that the distribution of supporting reasons generated by students varied from the different SSIs. In paper II, I explored students’ use of resources in relation to students’ study background (science majors and social-science majors) and gender. The results showed that social-science majors and females generated more numbers of reasons and also showed a larger amount of multi-disciplinary resources in their supporting reasons. From the findings of this thesis, the SEE-SEP model was established as a suitable model used to analyze students’ resources of supporting reasons while arguing about SSIs. Furthermore, the potential for applying the SEE-SEP model in teachers’ SSI-teaching and students’ SSI-learning is suggested. The implications to research and teaching are also discussed.

Parenthood is generally marked as a joyous event, though some research indicates that the birth of a child can possibly involve a difficult and complicated adjustment period for new parents (Ceballo, Lansford, Abbey, & Stewart, 2004). Questions regarding heritage and biological ties typically occur after developmental milestones, for example, births, marriages, and deaths, for adult adoptees. Horowitz (2011) offered that in order to understand the uniqueness of adoptees’ experiences and the specific needs they may have during childhood, it is vital to study the entire adoptee trajectory into adulthood, in order for adoptive parents and society to prepare successfully and launch adoptees into adulthood. This study explored how adult adoptees view parenthood through the lens of their own upbringing in Canada. There are gaps of information in the literature on how adoptees undertake parenting and how they approach becoming parents. In addition, how adoptees recognize themselves in their own children whether their children are adopted or not and how adoptees bond with their children. This study is an effort to address this gap offering recommendations for future research. Using an attachment theory framework while employing a mixed methods approach through an exploratory-sequential design, highlighted results include: adult adoptees struggle with identity issues and their adoption experiences do impacted the way they become parents and how they view themselves as parents.

One in nine North American women will be diagnosed with breast cancer in their lifetime and most will receive chemotherapy as part of their treatment. Although advances in treatment have increased survivorship, some research suggests chemotherapy results in cognitive deficits in a subset of recipients, a condition known as chemo-fog, thereby compromising quality of life. However, inconsistencies in methodology and neuropsychological assessment have complicated comparison of findings. The first objective of this thesis was to review the methodological issues with an emphasis on the quantitative techniques typically employed. A comparison of group and individual based analyses found negligible effects for both univariate and multivariate approaches while individual based analyses identified severe declines in function in a subset of participants. A standardized-regression based (SRB) approach was recommended as the method of choice. Furthermore, it was recommended that the number of tests be limited since comprehensive batteries can complicate identification due to increased risk of misclassification. Therefore, the second goal of the thesis was to evaluate the sensitivity of a reduced battery to the declines associated with chemo-fog. A comprehensive neuropsychological battery comprising 23 tests was compared to a subset of nine tests. SRB analyses demonstrated that a more selective battery was equally useful and may be appropriate for identification of chemo-fog. Given the variability in the composition of neuropsychological test batteries, the final aim of this thesis was to compare the structure of the theoretical cognitive domains with ones identified through exploratory factor analyses (principle axis factoring) to evaluate the convergence between the two. The results demonstrated there is statistical support for the conceptual framework that underlies the composition of the domains. The contributions of this thesis include providing methodological guidelines for those conducting future research in this area to ensure that results are comparable across studies and are meaningful, and evaluating the utility of a screening battery to facilitate identification of chemo-fog. In addition, it was demonstrated that despite the lack of professional guidelines informing the selection and construction of neuropsychological test batteries, there is statistical evidence to support the practice of grouping tests into domains based on theoretical grounds.

Despite its name, Corporate Social Responsibility is not exclusively a concept for large corporations; however, previous studies have primarily focused on CSR within larger firms. As Small and Medium sized Enterprises both possess unique characteristics, and are important actors in the global economy, this is an area that deserves deeper research. As pressure from internal and external stakeholders are mounting, firms needs to ensure that they are following the current rules of the game. As such, firms put pressure on their suppliers, in order to protect their business. Consequently, a failure to cope with this pressure from the supplier’s part is a potential source for a conflict. Thus, the actual CSR standards used by a focal firm, has a direct link to a potential conflict within an offshoring relationship. Hence, this thesis aims to investigate how Swedish SMEs apply CSR policies and activities regarding social issues in their organisations, and how these policies and activities affect conflicts between Swedish SMEs, and their foreign suppliers. Three Swedish SMEs where interviewed, and their CSR activities, and conflict management were analysed. While all the three firms used CSR to a various degree, this research suggests that the nature and direction of the CSR activities are largely determined by the industry in which the firm operates. Furthermore, SMEs typically lack the power to enforce their CSR standards on their suppliers. However, SMEs can act in the roles of supervisors, in order to communicate that CSR is an important aspect within a relationship. The case companies also illustrated that clear goals of CSR activities within SMEs, connected to the actual business goals, aids in the establishment of CSR in small firms. Finally, none of the three case firms experienced any conflicts with their suppliers, based on social issues within CSR. Instead, this research suggests that SMEs avoid conflicts, by emphasising a careful selection of suppliers.

Background: When a patient suffer from a disease and is in need of palliative care, it is normal to have existential questions and thoughts. For some patients these questions can be painful and the nurse need to have knowledge about dealing with these kind of questions and thoughts to be able to relieve and/or prevent this kind of suffering. Aim: The aim was to describe how the nurse can prevent the existential suffering among patients with palliative care. Method: A literature-based study was based on eight qualitative studies. Results: The results showed that nurses meet patients in the palliative care environment which may suffer from existential problems when their questions and thoughts don´t get answered. It showed that the most important a nurse can do is to give time to these calls and build up a safe relation to the patient. This allows the nurse to read the patients existential questions and observing possibly suffering. The result is organized in two categories "To see and confirm" and " To listen and give support" and see subcategories " Use body language", " Create reliable relationship", respond to the existential questions", "Give the patient time", " take help from others in hard situations" and "to focus on other things" Conclusion: It is easy to only focus on the physical illness while caring for a patient and believe that it is creating suffering. Extensive human suffering is not shown at first sight although it is just as important to relieve.
