The purpose of this thesis was to investigate environmental permits of landfills with respect to the appropriateness of risk assessments focusing on contaminant migration, structures capable to protect the environment, waste and leachate management and existing environmental impacts of landfills. According to the requirements, a risk assessment is always required to demonstrate compliance with environmental protection requirements if the environmental permit decision deviates from the set requirements. However, there is a reason to doubt that all relevant risk factors are identified in current risk assessment practices in order to protect people end environment. In this dissertation, risk factors were recognized in 12 randomly selected landfills. Based on this analysis, a structural risk assessment method was created. The method was verified with two case examples. Several development needs were found in the risk assessments of the environmental permit decisions. The risk analysis equations used in the decisions did not adequately take into account all the determining factors like waste prospects, total risk quantification or human delineated factors. Instead of focusing on crucial factors, the landfill environmental protection capability is simply expressed via technical factors like hydraulic conductivity. In this thesis, it could be shown, that using adequate risk assessment approaches the most essential environmental impacts can be taken into account by consideration of contaminant transport mechanisms, leachate effects, and artificial landfill structures. The developed structural risk analysing (SRA) method shows, that landfills structures could be designed in a more cost-efficient way taking advantage of recycled or by-products. Additionally, the research results demonstrate that the environmental protection requirements of landfills should be updated to correspond to the capability to protect the environment instead of the current simplified requirements related to advective transport only.

Online retail has experienced substantial growth due to the increased utilization of digital technologies. The growth in the industry has created numerous multinational corporations, which serve customers all around the world. As a result, the online retailers’ efforts in sustainability have been more often in publicity. Corporate Social Responsibility (CSR), the efforts going beyond the company’s interest in order to bring social good, have been discussed in the academic community for decades. While the various effects of CSR in retail and business generally have been realized, the research aims to make a contribution by examining the concept from the viewpoint of online retail by focusing on interaction at online discussion forums. The main research question asks: What is the role of online retailer CSR in the online discussion forum context? In order to answer this question, additional three sub-research questions are suggested: 1) What elements of CSR are relevant in the online retailer context? 2) How are discussion forums used in communication regarding CSR and online retail by different discusser types? 3) What kind of company perceptions and consumer behavior appear in online discussions of Amazon’s CSR? The study is qualitative of nature, using the content analysis research method to examine posts found from four different public online discussion forums. A qualitative, interpretative analysis was used, although quantitative measures regarding discussion posts were also presented. The analysis contains a coding process, where attributes are attached to discussion posts. As a result of the process, specific patterns can be indicated in order to categorize the posts. As the research uses Amazon as the case company, the case study method is also adopted. In the online retail context, ethics regarding the online retailer’s tax and labor policies are found as most relevant elements. Customers, using discussion forums to share their experiences and opinions regarding online retailer CSR efforts, are realized as the most prominent stakeholder. The research also highlights the role of online retailer employees providing details on internal business practices. However, the not realize the possibility to participate in discussions. Most discussion posts refer either to a positive, negative or mixed reaction towards CSR efforts, it is suggested that the concept is relevant also in online retail. Although online retailer CSR efforts are somewhat linked to company perceptions, the concept has a minimal role in consumer behavior. In online retail, CSR efforts can reduce the risk of being involved in discussions related to controversies. In addition, online retailer CSR efforts should communicate how the retailer contributes locally.

Legitimation of public policies that support the widespread plantings of transgenic crops presuppose, among other conditions, that (1) evidence supports that there are no unmanageable environmental risks and (2) there are no better ways to produce enough nourishing food that can dispense with the transgenics-oriented ways. This paper discusses: (a) the kinds of scientific inquiry that are needed to address (1) adequately, (b) the connections between investigations of (1) and (2), and (c) how these investigations are related with controversial social values.

The textile industry is one of the most polluting industries in the world. The amount of air and water pollution it causes puts a burden on the environment. There are companies who have taken the environmental and social aspects into account in the their production and chosen to operate in a green manner. This thesis studies how the phenomenon of green branding is seen from the perspectives of small Finnish textile companies. The theory used in this thesis has to do with green branding and identity building. The theory is used to analyze the results of the empirical findings. The main research question that the thesis aims to answer is how green branding is perceived within the Finnish textile industry. In order to answer the main research question, empirical data was collected from five relevant companies within the Finnish textile industry. The companies interviewed for the study were WST, Saana ja Olli, RCM, R-collection and Tiensivu. The study was conducted as a multiple case based study where multiple experts from green companies were interviewed. The experts were all owners or employees of companies that have a so-called green brand identity. The data was collected through semi-structured interviews, where the relevant experts from each company were interviewed either by themselves, in pairs or in groups. The data that was collected for this study was primary data, and the results of the study are mainly based on the experiences and opinions of the experts interviewed. The data collected does not cover the entire green textile industry within Finland, but study does however give a fairly comprehensive view of the phenomenon, as the textile industry in Finland is quite concise. The general findings of the study show that all experts from the companies interviewed agreed that a green brand identity does benefit their company in one way or the other. The findings also show contradictions with the older theory (eg. Charter et al. 1999, Pickett et al. 1995), and perhaps give a more modern view of the thoughts within the industry.

Autism is a developmental disorder that is characterized by abnonnal social interactions and communications as well as repetitive and restricted activities and interests. There is evidence of a genetic component, as 5% of younger siblings are diagnosed if their older sibling has been diagnosed. Autism is generally not diagnosed until age 3 at the earliest, yet it has been shown that early intervention for children with autism can greatly increase their functioning. Because of this, it is important that symptoms of autism are identified as early as possible so that diagnosis can occur as soon as possible to allow these children the earliest intervention. This thesis was divided into two parts. The first looked at the psychometrics of two proposed measures, the Parent Observation Checklist (POC), administered monthly, and the Infant Behavior Summary Evaluation (mSE), administered bimonthly, to see if they can be used with the infant population to identify autistic symptoms in infants who are at high risk for autism or related problems because they have an older sibling with autism. Study 1 reported acceptable psychometric properties of both the POC and IBSE in terms of test-retest reliability, internal consistency, construct validity and predictive validity. These results provide preliminary evidence that parent report measures can help to detect early symptoms of ASD in infants. The POC was shown to differentiate infants who were diagnosed from a matched group that was not diagnosed by 3 years of age. The second part of this thesis involved a telephone interview of parents who reported developmental and/or behavior problems in their high-risk infants that may be early signs of Autism Spectrum Disorder (ASD). During the interview, a service questionnaire was administered to see what interventions (including strategies recommended by the researchers) their at risk infants and affected older siblings were receiving, how satisfied the parents were with them and how effective they felt the interventions were. 3 Study 2 also yielded promising results. Parents utilized a variety of services for at risk infants and children with ASD. The interventions included empirically validated early intervention (e.g., ABA) to non-empirically validated treatments (e.g., diet therapy). The large number of nonempirically validated treatments parents used was surprising, yet parents reported being involved and satisfied, and thought that the services were effective. Parents' perceptions of their stress levels went down slightly and feelings of competence rose when they accessed services for their infants. Overall, the results of this thesis provide new evidence that parent-report methods hold promise as early detection instruments for ASD in at-risk infants. More research is needed to further validate these instruments as well as to understand the variables related to the parents' choice of early intervention for their at risk and affected children.

Existing research identifies preschoolers with communication delays as a population at risk for the development of behavioural concerns. This risk increases when additional environmental factors such as parental stress and family conflict are also present. Research has also shown that behavioural concerns can be stable over time when they develop early. However, early intervention has been shown to be effective in addressing these concerns. The effectiveness of early intervention in addressing both child and family outcomes increases when interventions are delivered in a family-centred approach. This research project made use of data related to child behaviour and parenting, gathered through the Family Resource Project which explored the parenting experiences and resource access and allocation decisions of families who have preschool children with and without communication delays. Cluster analysis was used to explore whether there were identifiable clusters of children and families within each sample. Interview data fi"om each identified family cluster was then explored further, to identify how parents described their child's behaviour and their experience of parenting. Results show that, within this sample, parents of preschoolers with communication delays described their child's behaviour and their experience of parenting differently than did parents of children without communication delays. Results also showed that within this sample parents experiencing parental stress and/or family conflict described their child's behaviour and their experience of parenting differently than did parents from other clusters. Results suggest support for early intervention and the use of family-centred intervention, particularly for families of children with communication delays.

This study examined adolescents' reported sexual and dietary health-risk behaviours and perceptions. Specifically, this study analyzed the data of 600 students (300 male~ 300 female) in grades 9, I 1, and OAC (mean, standard deviation). The mean age of the students in the sample is 16 with a standard deviation of 1.6. The study was a secondary analysis ofthe first-year data of a 3-year longitudinal study conducted by Youth Lifestyle Choices-Community University Research Alliance (YLC-CURA) on adolescents. To explore sexuality and dietary health, this study purposefully selected sections of the survey that represented sex and dieting behaviours of adolescents. Separate gender and age data analyses revealed different patterns among the variables. Specifically., findings revealed that adolescents who engaged in recent sexual activities were more likely to have a relatively more positive body image perception and were relatively more likely to engage in disordered eating. Across both genders and 3 age levels, adolescents reported that despite their unhealthy dietary habits they felt that dieting was not a high-risk behaviour. Results were discussed in terms of educational implication for sexual health programs.

The purpose of this research is to investigate through adult perceptions what factors have enabled and limited student participation in schoolyard gardening, and how to support student involvement in schoolyard gardening. It is a collective case study of three schools in the Toronto District School Board (TDSB, Ontario, Canada) that are currently running a schoolyard gardening project. Sixteen interviews were conducted during May and June, 2005, and photos of the three schoolyard gardens were taken. The results show that the common factors that have enabled student participation in schoolyard gardening at the three schools are teacher's initiative and commitment, principal's leadership and support, parental involvement and donations, and the TDSB's EcoSchools program and workshops. The common limiting factors are time, money, and the unions' "work-to-rule" issue. The ways to support student involvement include teachers integrating the gardening into the curriculum; parents making donations to the school and creating a family gardening culture; principals supporting in money or budget and taking the lead; the TDSB providing funding, awards, incentives, and more maintenance; and the Ontario Ministry of Education supplying funding, curriculum link, and teacher training.

This paper examines the factors associated with Canadian firms voluntarily disclosing climate change information through the Carbon Disclosure Project. Five hypotheses are presented to explain the factors influencing management's decision to disclose this information. These hypotheses include a response to shareholder activism, domestic institutional investor shareholder activism, signalling, litigation risk, and low cost publicity. Both binary logistic regressions as well as a cross-sectional analysis of the equity market's response to the environmental disclosures being made were used to test these hypotheses. Support was found for shareholder activism, low cost publicity, and litigation risk. However, the equity market's response was not found to be statistically significant.

Currently, there are a variety of concerns about the future of bouldering, a form of rock climbing, a t the Niagara Glen Nature Reserve near Niagara Falls, Ontario due to environmental impacts at the site. The purpose of this study was to describe the perceptions ofbouldering participants toward sustainable bouldering practices at the Niagara Glen. The methodological framework for this study was based on action research, which attempts to solve specific problems through having people in a community study, discuss, and act on those problems. Five separate focus group interviews elicited data from nineteen men and seven women, while there were twenty one men and ten women observed through participant observations at the Niagara Glen. Analysis was conducted through coding processes where data were compared repeatedly and then organized into themes. From the open coding process, two main themes were identified and interpreted as 1) Barriers to Sustainable Bouldering at the Niagara Glen Nature Reserve, and 2) Environmental and Social Role and Responsibility ofBoulde r ing Participants at the Niagara Glen. The implications of the findings include a variety of recommendations for the bouldering community and the Niagara Parks Commission to consider for future collaborative planning. Some of these recommendations include more open communication between all stakeholders at the Glen, additional leadership from local climbing access coalitions and the Niagara Parks Commission, and greater implementation of minimum impact practices from the bouldering community. Additionally, these implications are discussed through a three-part framework based on a conceptual intersection of sense of place, community empowerment, and sustainable recreational use as a way to potentially unify the bouldering community's voice and vision toward sustainable practice.

The primary objective of this non-experimental study was to examine the differences based on obesity-related health risk in terms of physical activity, sedentary behaviour and well-being in adults. Participants (N = 50; Mage = 38.50, SDage = 14.21) were asked to wear a SenseWear Armband (SWA) across a seven day monitoring period followed by a questionnaire package. Using the National Institute of Health’s (1998) criteria, participants were classified as either least, increased, or high risk based on waist circumference and Body Mass Index scores. Differences between these classifications were found in the amount of time spent in active energy expenditure for bouts of ten minutes or more (p = .002); specifically between least and high risk (p < .05). No other differences (p > .05) emerged. Participants’ also perceived the SWA as a practical and worthwhile device. Overall, these findings provide practical applications and future directions for health promotional research.

Résumé La prédominance de l'obésité qui touche les enfants et les adultes a augmenté dans le monde entier ces dernières décennies. Les différentes études épidémiologiques ont prouvé que l'obésité est devenue une préoccupation profonde de santé aux États-Unis et au Canada. Il a été montré que l'obésité a beaucoup d’effets sur la santé ainsi il serait important de trouver différentes causes pour le gain de poids. Il est clair que l'obésité soit la condition de multiples facteurs et implique des éléments génétiques et environnementaux. Nous nous concentrons sur les facteurs diététiques et particulièrement le fructose où sa consommation a parallèlement augmenté avec l'augmentation du taux d'obésité. La forme principale du fructose est le sirop de maïs à haute teneur en fructose (HFCS) qui est employé en tant qu'édulcorant primordial dans la plupart des boissons et nourritures en Amérique du Nord. Il a été suggéré que la prise du fructose serait probablement un facteur qui contribue à l’augmentation de la prédominance de l'obésité. L'objectif de cette étude était d'évaluer s'il y a un rapport entre la consommation du fructose et le risque d'obésité. Nous avons travaillé sur deux bases de données des nations Cree et Inuit. Nous avons eu un groupe de 522 adultes Cree, (263 femmes et 259 hommes) dans deux groupes d'âge : les personnes entre 20 et 40 ans, et les personnes de 40 à 60 ans. Nous les avons classés par catégorie en quatre groupes d'indice de masse corporelle (IMC). L'outil de collecte de données était un rappel de 24 heures. En revanche, pour la base de données d'Inuit nous avons eu 550 adultes (301 femmes et 249 hommes) dans deux groupes d'âge semblables à ceux du Cree et avec 3 catégories d’indice de masse corporelle. Les données dans la base d'Inuit ont été recueillies au moyen de deux rappels de 24 heures. Nous avons extrait la quantité de fructose par 100 grammes de nourriture consommés par ces deux populations et nous avons créé des données de composition en nourriture pour les deux. Nous avons pu également déterminer les sources principales du fructose pour ces populations. Aucun rapport entre la consommation du fructose et l’augmentation de l’indice de masse corporelle parmi les adultes de Cree et d'Inuit n’a été détecté. Nous avons considéré l’apport énergétique comme facteur confondant potentiel et après ajustement, nous avons constaté que l'indice de masse corporelle a été associé à l’apport énergétique total et non pas à la consommation du fructose. Puisque dans les études qui ont trouvé une association entre la consommation de fructose et l’obésité, le niveau de la consommation de fructose était supérieure à 50 grammes par jour et comme dans cette étude ce niveau était inférieur à cette limite (entre 20.6 et 45.4 g/jour), nous proposons que des effets negatifs du fructose sur la masse corporelle pourraient être testés dans des populations à plus haute consommation. Les essais cliniques randomisés et éventuelles études cohortes avec différents niveaux de consommation de fructose suivis à long terme pourraient aussi être utiles. Mots clés : fructose, sirop de maïs à haute teneur en fructose (HFCS), obésité et poids excessif

Résumé Le but de cette thèse est de comprendre les représentations du risque chez les jeunes de la rue. Plus précisément, elle s’intéresse à appréhender les constructions du risque que font les jeunes de la rue eux-mêmes, d’autant plus que ces jeunes sont définis comme un groupe à risque. Si le risque est plus souvent défini de manière stricte comme le mal éventuel, dans cette étude, il est défini plus largement intégrant l’idée des opportunités et prises de risque. Ancrée dans une perspective double du constructionnisme social et de l’interactionnisme symbolique, cette recherche a exploré les savoirs des jeunes sur les risques qu’ils vivaient dans les contextes observés et la manière dont ils les appréhendaient. Pour y parvenir, cette recherche s’inscrit dans une approche ethnographique pour mieux comprendre le monde des jeunes de la rue, utilisant des méthodes d'observation participante et dévoilée et des entrevues informelles variées. Cette approche globale permet de saisir comment les jeunes définissent leur capacité à estimer, gérer, éviter ou prendre des risques. L’utilisation d’une perspective longitudinale (de un à deux ans) et les relations de confiance bâties avec ces jeunes, ont permis de suivre comment la construction identitaire des jeunes observés a influencé leurs perception du risque et leurs pratiques de débrouillardise. En outre, les liens établis ont permis de révéler les points de vue singuliers des jeunes mais aussi leurs savoirs expérientiels relatifs aux risques. Il s’agit dans cette étude de montrer à partir des théories générales qui définissent nos sociétés comme des sociétés du risque, comment des individus, identifiés comme appartenant à un groupe à risque, définissent et gèrent leurs risques à partir de leur propre expérience et point de vue afin de révéler la diversité et la complexité des expériences et savoirs des jeunes de la rue à l’endroit du risque. En effet, cette thèse montre qu’un ancrage dans une sociologie du risque permet de sortir de l’image de victime ou de déviance associée généralement aux jeunes de la rue mais qu’elle demeure marquée par la promotion de la sécurité légitimant intervention et régulation de la situation des jeunes de la rue tout en ignorant l’expérience même des jeunes. Les discours sur les risques associés à la rue sont alors inscrits dans une logique d’expertise. Cette étude vise à sortir de ces préconceptions des risques pris par les jeunes de la rue pour au contraire s’attarder à comprendre comment se définit le risque à partir du sens que les jeunes accordent et les expériences qu’ils en ont. Mots clés: jeunes itinérants, jeunes de la rue, le risque, à risque, victimisation, déviance, identité.
