The overall aim of this thesis was to investigate postural balance, physical activity, physical capacity and their associations in young people (16-20 years) with intellectual disability (ID), mild to moderate. The aim was also to study the reliability and concurrent validity of postural balance tests. To evaluate postural balance, one assessor used five common postural balance tests and one new test. The tests were performed twice for 89 young people with ID (one to twelve days apart). Intraclass correlation coefficients greater than 0.80 were achieved for four of the common balance tests: Extended Timed Up and Go Test (ETUGT), Modified Forward Reach Test (MFRT), One-Leg Stance Test (OLS), and a Force Platform Test (FPT). The smallest real difference ranged from 12% to 40%; less than 20% is considered to be low. For the six balance tests, the concurrent validity varied between none to low. Falls are more common for young people with ID compared to young people without ID. One reason could be impaired postural balance. The postural balance for young people with ID has not been thoroughly investigated. Therefore, five balance tests and three muscle strength tests were used to compare young people with ID with an age-matched control group without ID (n=255). The young people with ID had significantly lower scores on most of the postural balance tests and muscle strength tests of the trunk and lower limbs. Muscle strength, height, and body mass index had no strong association with postural balance. The results also illustrated that young people with ID did not rely more on vision for their balance ability compared to peers without ID. It seems that postural balance is impaired for young people with ID when evaluated with common tests. An everyday situation is to react to unexpected balance disturbances to avoid falls by using different postural responses. Since young people with ID seem to fall more often than peers without ID, it is valuable to investigate if those postural responses are different between the groups. Therefore, young people with and without ID (n=99) were exposed to six backward surface translations and several postural muscle responses were evaluated: muscle synergies and strategies, muscle onset latency, time-to-peak amplitude, and adaptation. The responses of the investigated muscles – the gastrocnemius, the biceps femoris, and the erector spinae L4 level – were measured using electromyography. The results showed that there were no differences between the two groups with respect to synergies or strategies, muscle onset latency, and time-to-peak amplitude. An overall pattern was seen, that young people with ID adapted their muscle response slower in all three muscles than peers without ID, but this pattern was not statistically significant. Studies have shown that people with ID have impaired postural balance, a lower level of physical activity, and lower aerobic capacity compared to people without ID. The association is however not investigated. Therefore, postural balance (postural sway indirectly measured with the subjects standing on a force platform), physical activity (measured with a pedometer), and aerobic capacity (measured with a sub-maximal ergometer cycle test) were used to assess young people with and without ID (n=106). To investigate the subjects’ view of their own health, the subjects completed an adapted questionnaire that addressed their perceived health. The analysis showed no significant associations between postural balance, level of physical activity, and aerobic capacity. The subjects in the ID group, both men and women, had significantly lower aerobic capacity compared to subjects without ID. The answers from the health questionnaire did not correspond to the measured outcomes from the physical tests for young people with ID. In conclusion, ETUGT and MFRT can be used to evaluate change in postural balance over time in young people with mild to moderate ID. The low concurrent validity suggests that the postural balance tests probably challenge various subsystems. Young people with ID have impaired postural balance and perform lower on muscle strength tests than age-matched controls. Postural muscle responses after external perturbations seem to be similar for young people with and without ID, but the ability to adapt muscle responses after repeated perturbations appears to be slower for young people with ID. The studies in the thesis also indicate that young people with ID have reduced level of physical activity and lower aerobic capacity. The lack of association between the different physical functions indicates that they should be evaluated and exercised separately. Young persons with ID might have more difficulty realising the health advantage of being physically active, as they do not seem to make this connection. Because of this, it is important that parents/guardians, school staff, physiotherapists, and others encourage them to participate in physical activity.

This theises aims to extend the understanding of how representation of gender is produced and reproduced in the young women’s magazine Frida. We examine this through analyzing pictures of male and female celebrities in a selected number of magazines from the year of 2013. We use a quantitative analysis of the pictures, as well as a supplementary quantitative analysis of ajectives used to describe male and female celebrities in captions. We research what types of patterns we can find in these analyses that construct representations of gender, also surveying how the celebrities in the magazine look. Our analysis shows us that the context of Frida contains several recurring visual patterns that preserves a representation of men being superior to women. We also find that for both men and women in the magazine- their attractive exterior is their most prominent attribute. That is not only perceived visually, but also reinforced by the editorial text. The result also shows us that the celebrities shown in the Frida is a very homogeneous group, with very similar attributes.

The decline thesis proposes that political participation among young people has declined steadily and alarmingly since the 1960s. New research proposes that young people have not been simply abstaining from political participation but that they have been engaging in new or alternative forms of participation like demonstrating, signing petitions and expressing themselves politically in the market. This paper asks two questions---who are these alternative participators and what explains why they have turned to these new forms? The results indicate that young people engage with alternative forms of political participation more than they engage with more traditional forms like joining political parties and lobbying Congress. Furthermore, the results show that the theory of postmaterialism does explain in part what leads some young people to participate in these alternative forms more than others.

While overall road deaths in Australia have fallen since the late 1980's and the impact of road-safety advertising appears to be positive, alcohol-related road fatalities remain the leading cause of death among young Australian adults. Fatality and injury rates continue within this cohort despite increases in alcohol-related knowledge, continuing education efforts in the Australian school system, increased funding for police enforcement and high media presence of road safety advertising (Peder et al 2004). Notwithstanding advances in communication technologies, highly graphic, emotional, shock style television advertising remains the primary medium for road safety message dissemination. Rather than targeting those highest at-risk for drink driving, road safety advertisements typically target an undifferentiated general audience. To date understanding the process by which road safety advertising influences attitudes and behaviour has been the centre of fear arousal research. Nonetheless, there has been little examination of how young adults who differ in drink-driving risk-propensity (high versus low) respond to and process anti-drink driving advertisements designed to modify an avoidable behaviour. Taking a receiver oriented approach, the focus of this study examines how young adult, novice drivers who differ in 'need-for-sensation' (NFS) risk propensity respond to, and process, anti-drink driving advertisements that differ in arousal capacity (i.e. high, low sensation-value). The investigation was conducted in two stages: Study 1 (qualitative) and Study II (quantitative). Study I, the qualitative phase, explored by focus group interviews attitudes, perceptions, beliefs and experiences of sixty young adults aged 18 to 25 years towards alcohol consumption, drink-driving, and anti-drink driving advertising. The major qualitative finding is that young adults characterise drink-driving as a rational, deliberate, planned and accepted behaviour. Young adults were aware of the choices available for not drinking and driving and were aware of the health, social and physical (self and property) risks associated with alcohol consumption and associated behaviours. Nonetheless, the short-term personal experiences of revelry and group cohesion were more pertinent to them on an everyday basis. Alcohol consumption and drink-driving behaviour did not appear to differ between university and nonuniversity students or gender, yet there were differences in attitudes and behaviour across the degree studied within the university cohort. Study II, the quantitative phase, was segmented into three sections. First, the study provides empirical support for NFS as a relevant a priori individual differences segmentation variable for differentiating between those more likely, versus less likely, to engage in responsible drink-driving behaviour. As expected low NFS individuals were more likely to not drink and drive. Second, findings support an interaction effect between an advertisement's sensation value and individual differences variable, NFS, on response outcomes. High NFS individuals engaged in higher levels of adaptive appraisal on the high sensation-value advertisement condition as compared to the low sensationvalue advertisement condition. Low NFS individuals did not discriminate across either advertisement condition. Adaptive appraisal was not counteracted by a corresponding increase in maladaptive appraisal. Both high and low NFS individuals viewed the high sensation-value advertisement condition with high levels of perceived threat and viewed the low sensation-value advertisement with higher levels of perceived efficacy. Yet, although high NFS individuals viewed the high sensation-value advertisement with high levels of threat they simultaneously viewed this advertisement with low levels of perceived efficacy. Third, NFS was not found to be a strong predictor moderating the relationship between message processing (cognitive, sensory, narrative) and response outcomes. The findings indicate strong support for a direct relationship between two modes of message processing: cognitive and narrative processing and response outcomes. Message recipients processed anti-drink driving advertisements via two routes to persuasion. There was stronger cognitive processing evident on advertisements possessing high arousal capacity, whereas stronger narrative processing was evident on low arousal capacity advertisements. This study suggests that those advertisements that possess high arousal capacity have the capability of facilitating attention to the central argument, the consequences of drinking and driving, as well as how drinking and driving may affect the message recipients' life. Alternatively, those messages that impart high levels of rational information have the capability of increasing attention to the peripheral cues in the message. It is also suggested that different styles of message processing, central versus peripheral, act in a synergistic way to influence response outcomes which indicates that there is no single route to persuasion. Individuals process messages in a complex manner attending to various signals in order to evaluate various components of the message. For road safety practitioners and social marketers the results of this study illustrates practical benefits for the design of anti-drink driving advertisements based on the segmentation variable NFS. The finding that high NFS individuals require advertisements that possess high levels of arousal capacity (i.e.: high in sensation-value) is an important development. Importantly, low NFS individuals do not discriminate in accepting the recommendations of advertisements that differ in arousal capacity clearly suggests that they accept messages regardless of their arousal capacity. This finding indicates that the goal of road traffic authorities, advertising agencies and social marketers should be directed towards targeting high NFS individuals who are more atrisk for a drink-drive fatality. That message recipients process anti-drink driving messages via two routes to persuasion indicates that message designers need to consider the mix between the sensation-value of the message and consideration of the way message recipients' process the message, i.e. via central/systematic versus peripheral/heuristic components of the advertisement. Further investigation into the dual processing of anti-drink driving advertisements once individuals are exposed to the message is warranted to further understand the psychological processes influencing message processing. The findings of this research have important implications for both practitioners and academics. This research has provided an insight into the complexity of young adult's response outcomes and message processing of fear-based anti-drink driving messages.

INTRODUCTION AND BACKGROUND: Cerebral palsy (CP) is the most common physical disability in childhood with a prevalence of approximately 2-2.5 per 100 live births. Improvements in paediatric care have increased the survival of individuals with CP. Overall 90% are expected to grow into adulthood yet little is known about the outcomes of young adults with this condition. In order to provide holistic services for this population, an understanding of various aspects of their lives is required. / AIMS: To examine the outcome of young adults with CP from the perspective of perceived health status, functional ability, pain, quality of life (QOL), social participation, and healthcare service utilizations, compared with their able-bodied peers. To explore the determinants that contribute to the variation of these outcomes in the context of impairments, activity, participation, and personal and environmental factors. / METHODS: This is a population based cross sectional study of young adults with CP based on the WHO International Classification of Functioning, Disability and Health (ICF) model. A cohort of 335 young adults with cerebral palsy born in Victoria, aged 20 to 30 years, was recruited from the Victorian Cerebral Palsy Register. Data of typically developed peers selected from the Household, Income and Labour Dynamics in Australia Survey 2004 were used for comparison for the outcomes of perceived health, pain, and social participation. Data from a population-based sample of 751 young adults in U.S. were used for comparative analyses of QOL. Participants were asked to complete a multidimensional questionnaire by self report, or proxy report by parents or carers for those with intellectual or severe physical impairments. The questionnaire was comprised of the Quality of Life Instrument for Young Adults, the Short Form-36 Health Survey Questionnaire version 2, the Gross Motor Function Classification System, the Barthel Index, and a demographic section. / RESULTS: A total of 335 young adults with CP participated; 207 (62%) were able to self report and 128 (38%) were proxy reported. Compared with their able-bodied peers, self reported physical health in this population was lower but mental health was similar. Gross motor function, independence in self care, and limb distribution together explained 60% of the variance in the physical health data. They experienced more pain, impaired function, and reduced social participation, but despite this, their contact with medical and allied health professionals was low. Pain was linked with limb distribution and had a negative impact on functional ability, employment participation and QOL. Impaired functional ability, intellectual disability, and communication impairments had major effects in reducing social participation. Self reported QOL was similar to their peers in social relationship and environmental context domains, but was lower in the domains of physical health, psychological well-being, and role function. The impact of CP on the individuals’ QOL was on physical and functional aspects, and sometimes on social relationships, but not on psychological well-being. / CONCLUSION: This study has demonstrated that greater efforts are needed to improve the health, function, QOL, and social participation in individuals with CP, accompanied by more research to monitor the effectiveness of interventions for them.
