The overall purpose of this thesis is to describe and analyse interpersonal behaviour in career counselling sessions. The importance of the relationship in counselling for the outcome of sessions has been acknowledged in earlier research. How the actual interaction process between client and career counsellor looks like has been sparsely investigated. The present research explores expected, experienced behaviours and self-image of 15 adolescent clients’ and counsellors’ dyads in career counselling. The research was guided by interpersonal theory and the model of structural analysis of social behaviour (SASB) developed by Lorna Smith Benjamin. The research focuses on four different aspect of interpersonal behaviour. First, the significance of different behaviours by the clients and the career counsellors related to session evaluation. Second, the significance of expected and experienced similarity in perceptions of self and other behaviours related to session evaluation. Third, differences of perceived behaviours and possible influence by self-image over the course of sessions and fourth, comparing the influence of positive and negative self-image to expected and experienced behaviours, perceived important events during session and session evaluation session by clients’. Results indicate the importance for clients to become close to the career counsellor in session, while the career counsellors’ encouragement of clients’ independency during sessions showed to be of less importance for the clients’. This pattern imply a difficult balance act for career counsellors between providing a safe and close relationship and promoting independence and exploration for the clients. Further, it was found that career counsellors had difficulties in identifying their own contributions to a positive session evaluation, indicating a problem for the career counsellors’ to make conscious adjustments of behaviours. The degree to which client and career counsellor agreed of their behaviours only mattered for experiences of the career counsellors’ behaviour when related to their evaluation of session. Only minor tendencies of influence by the career counsellors’ self-image of clients’ perceived differences in behaviours were found. Self-image played a significant role in how the clients’ expected and experienced behaviours, perceived important events in session and in their session evaluation. Clients’ with positive self-image showed consistently more positive perceptions on each of the involved variables.

Background: Due to the fashion industry being one of the most polluting industries in the world with more clothing than ever being thrown away, attention has been brought to the need for more sustainable clothing behaviours. Therefore, the in-store recycling boxes have been introduced as an alternative for recycling. Previous literature has focused mainly on companies’ perspectives or consumers purchasing behaviours, hence there is a gap for literature on consumers’ disposal and recycling behaviours. Purpose: The purpose of this study is to examine what factors influence consumers’ intentions to use in-store recycling boxes. This will be done by applying the Theory of Planned Behaviour by Ajzen (1991). Method: A qualitative approach in terms of two focus groups and two individual interviews was applied. The study was made on the consumers’ perspectives, and therefore the participants were 11 Swedish female students. Conclusion: The empirical findings and analysis toward previous literature and theoretical framework revealed that the main factors influencing consumers’ intentions to use in-store recycling boxes are lack of information about the recycling process, the possibility to drop off damaged clothing, and the developing possibility to make new clothing out of recycled materials. The lack of information had the greatest impact, which was unfavourable toward the intention to perform the behaviour and hence obstructed the participants from using in-store recycling boxes.

Much work has been done in communicating environmental messages about climate change to promote pro-environmental beliefs and behaviours, yet individual-level behavioural changes are not occurring rapidly enough to make meaningful reductions in environmental harm. Studies have shown that although information-based and scientific means of communicating about climate change are the most common strategies, they are largely ineffective in encouraging pro-environmental behaviour. As an alternative to these fact-based narratives, stories are proposed as effective tools for environmental communication and promoting behavioural change. To determine the impact of the narrative structure of climate change communication on behaviour, this study examined how exposure to fact-based and story-based narrative structures of environmental messages differentially influence the extent of engagement in pro-environmental consumption behaviour. The Theory of Planned Behaviour (TPB) was used as a framework to examine the attitudinal and behavioural responses to the story-based and fact-based communication conditions. Specifically, we examined the relationship between non-consumption attitudes, subjective norms, perceived behavioural control, behavioural intentions, and non-consumption behaviour, and explored how narrative structure influences the TPB processes for non-consumption. Participants (n=291) were randomly assigned to read a story or factsheet about the environmental consequences of overconsumption of material goods, or a non-relevant text. Pre- and post-test measures of pro-environmental consumption behaviour were conducted 14 days apart. Post-test attitudes, subjective norms, perceived behavioural control, and behavioural intentions towards practicing non-consumption were also measured. Results demonstrated that both story-based and fact-based narratives were effective tools for promoting pro-environmental consumption behaviour, providing some support for the information deficit theory. Four domains of pro-environmental consumption behaviour were determined as non-consumption, reuse, activism, and green shopping behaviour. The story-based narrative was more effective than the fact-based narrative and the control narrative in increasing non-consumption and green shopping practices, while activism and reuse behaviour were not influenced differently by narrative structure. The TPB was found to be a useful model for assessing non-consumption, such that non-consumption behaviour was predicted by attitudes, perceived behavioural control and subjective norms through the mediating role of behavioural intentions. Non-consumption attitude was the strongest predictor of intentions, and subjective norm was the weakest predictor of intentions. Narrative structures did not have significant effects on the participants’ reported non-consumption attitudes, subjective norms, perceived behavioural control or intentions, nor on the relationships between the TPB constructs. The findings suggest that story-based narrative structures are effective tools for delivering climate change information to broad audiences and encouraging pro-environmental behaviour. However, the role of information-based communication should not be discounted. The findings also contribute to the body of research on pro-environmental consumption behaviour by providing a deeper understanding of the psychological mechanisms of non-consumption, an essential yet understudied domain of sustainable behaviour. / Graduate / 2023-01-12

A review of anatomical and behavioural studies of the limbic system suggests that some structures which Papaz proposed as the central mechanism of emotion might be involved in food hoarding behaviour. Various structures in Papez· circuit were destroyed surgically and observations were taken on subsequent changes in food hoarding behaviour. In addition, observations were made on nest building behavior and on avoidance performance. It was found that rats with bilateral damage to the mammillothalamic tract and mammillary body were severely depressed in hoarding and avoidance behaviour. Septal damage caused a less severe deficit in both behaviours while hippocampal, domical or thalamic damage did not have a significant effect. A pilot study of hoarding behaviour in the hamster was carried out. / Thesis / Master of Arts (MA)

O comportamento do usuário afeta o impacto ambiental gerado durante a fase de uso das edificações e de produtos em geral. O Design para o Comportamento Sustentável (DCS) é uma abordagem que visa tornar o comportamento do usuário mais sustentável através do design do produto. Apesar de estar sendo estudada principalmente nas duas últimas décadas, poucos estudos examinam a eficácia dessa abordagem e a aplicam em edificações escolares. A aplicação de estratégias de DCS em edificações escolares pode trazer benefícios, uma vez que as crianças têm influência no ambiente em que estão inseridas e no comportamento dos adultos ao seu redor. O objetivo deste estudo é propor e avaliar uma solução desenvolvida a partir de estratégias de DCS para criar um ambiente escolar que torne o comportamento do usuário mais sustentável. Primeiramente, os comportamentos que afetam o impacto ambiental nas edificações escolares foram identificados. Após, um kit de adesivos para sanitários (EcoSticker) foi proposto e implementado em duas escolas. O consumo de recursos (energia, papel higiênico, papel toalha e sabão) antes e após a intervenção foi medido. Posteriormente, entrevistas, questionários e um workshop foram realizados para entender melhor os dados de consumo coletados e a percepção dos usuários sobre o kit. O consumo de energia diminuiu nas duas escolas, demonstrando que o EcoSticker pode alterar positivamente o comportamento do usuário. A partir deste trabalho foram obtidos os potenciais benefícios e limitações da aplicação de estratégias de DCS em edificações escolares. / The user behaviour affects the environmental impact generated during the usage phase of buildings and products in general. Design for Sustainable Behaviour (DfSB) is an approach that focus on influence users to behave more sustainably through the product design. Although it has received attention particularly in the last two decades, few studies examined the effectiveness of such approach and apply it on school buildings. The application of DfSB strategies in school buildings can bring some benefits, once children have influence on their environment and on how adults behave. The goal of this study is to propose and test an artefact developed according to the DfSB strategies to create a school environment that leads to a more sustainable behaviour. First, behaviours on school buildings that affect the environmental impact were identified. Then, a toolkit for washrooms (EcoSticker) was proposed and implemented in two schools. The resources consumption (energy, toilet paper, paper towel and soap) prior and after the intervention was measured. Afterwards, interviews, questionnaires and a workshop were carried out to further understand the consumption data collected and users’ perception of the toolkit. The consumption of energy have decreased in both schools, demonstrating that the EcoSticker toolkit can change user behaviour positively. At the end, the potential benefits and constrains in applying DfSB strategies on school buildings were discussed.

The diagnosis of children with Attention Deficit Hyperactivity Disorder (ADHD) has increased over the last few years in Australia. ADHD is currently understood largely through a medical perspective, and in that context, the treatment recommended is stimulant medication. ADHD is a mental health label given to children who exhibit challenging behaviour. These children are diagnosed according to the categories stated in the Diagnostic Statistical Manual (DSM) – IV. To date, there is no medical test children can undertake to show that they ‘have’ ADHD. This research focuses on an alternative view of ADHD. Focussing upon families’ experience of ADHD, and the medicalisation of children’s behaviour, it argues that behaviour is socially influenced and constructed. It is because insufficient attention has been given to the family experience and the social implications of ADHD, that the child is often seen as ‘the problem’. The gap in our understanding of ADHD is situated in our understanding of the broader social context. To challenge this I will explore perceptions of the ‘good child’, ‘good mothers’ and the social consequences of inappropriate behaviour. Each family was interviewed five times every three months over a two-year period. Their stories and experiences are presented in this thesis.

The increasing use of polyethylene in diverse applications motivates the need for understanding how its molecular properties relate to the overall behaviour of the material. Although microstructure and mechanical properties of polymers have been the subject of several studies, the irreversible microstructural rearrangements occurring at large deformations are not completely understood. The purpose of this thesis is to describe how the concepts of Continuum Damage Mechanics can be applied to modelling of polyethylene materials under different loading conditions. The first part of the thesis consists of the theoretical formulation and numerical implementation of a three-dimensional micromechanical model for crystalline polyethylene. Based on the theory of shear slip on crystallographic planes, the proposed model is expressed in the framework of viscoplasticity coupled with degradation at large deformations. Earlier models aid in the interpretation of the mechanical behaviour of crystalline polyethylene under different loading conditions; however, they cannot predict the microstructural damage caused by deformation. The model, originally due to Parks and Ahzi (1990), was further developed in the light of the concept of Continuum Damage Mechanics to consider the original microstructure, the particular irreversible rearrangements, and the deformation mechanisms. Damage mechanics has been a matter of intensive research by many authors, yet it has not been introduced to the micromodelling of semicrystalline polymeric materials such as polyethylene. Regarding the material representation, the microstructure is simplified as an aggregate of randomly oriented and perfectly bonded crystals. To simulate large deformations, the new constitutive model attempts to take into account existence of intracrystalline microcracks. The second part of the work presents the theoretical formulation and numerical implementation of a three-dimensional constitutive model for the mechanical behaviour of semicrystalline polyethylene. The model proposed herein attempts to describe the deformation and degradation process in semicrystalline polyethylene following the approach of damage mechanics. Structural degradation, an important phenomenon at large deformations, has not received sufficient attention in the literature. The modifications to the constitutive equations consist essentially of introducing the concept of Continuum Damage Mechanics to describe the rupture of the intermolecular (van der Waals) bonds that hold crystals as coherent structures. In order to model the mechanical behaviour, the material morphology is simplified as a collection of inclusions comprising the crystalline and amorphous phases with their characteristic average volume fractions. In the spatial arrangement, each inclusion consists of crystalline material lying in a thin lamella attached to an amorphous layer. To consider microstructural damage, two different approaches are analyzed. The first approach assumes damage occurs only in the crystalline phase, i.e., degradation of the amorphous phase is ignored. The second approach considers the effect of damage on the mechanical behaviour of both the amorphous and crystalline phases. To illustrate the proposed constitutive formulations, the models were used to predict the responses of crystalline and semicrystalline polyethylene under uniaxial tension and simple shear. The numerical simulations were compared with experimental data previously obtained by Bartczak et al. (1994), G‘Sell and Jonas (1981), G‘Sell et al. (1983), Hillmansen et al. (2000), and Li et al. (2001). Our model’s predictions show a consistently good agreement with the experimental results and a significant improvement with respect to the ones obtained by Parks and Ahzi (1990), Schoenfeld et al. (1995), Yang and Chen (2001), Lee et al. (1993b), Lee et al. (1993a), and Nikolov et al. (2006). The newly proposed formulations demonstrate that these types of constitutive models based on Continuum Damage Mechanics are appropriate for predicting large deformations and failure in polyethylene materials.
