Modelling Viking Migration to the Inner Hebrides

Until recently, the idea of large-scale Viking settlement in Scotland’s Inner Hebrides was considered unlikely. Despite a conspicuous absence of documentary evidence, the area’s long-standing Gaelic heritage was seen as proof of linguistic and cultural continuity from its Dalriadan heyday. By developing the narrative to consider other types of evidence, however, it is clear that the Norse impact on these islands was far from insignificant. This paper will review the historical record in the light of material evidence and linguistic artefacts such as place-names. After questioning aspects of currently popular approaches to ‘predatory’ migration, it will then examine how reappraisal of the practicalities of Viking Age immigration might help to inform a revised model for Norse settlement in the region

An interpretative phenomenological analysis of the patient experience of awake craniotomy: brain tumour diagnosis to discharge

Objectives. Previous research exploring the patient experience of awake craniotomy (AC) has yielded contrasting accounts. The current study aimed to explore the lived experience of having undergone an AC in the United Kingdom. Design. This was a qualitative, semi-structured interview study. Interviews were audio-recorded and transcribed verbatim. Data were analysed using interpretative phenomenological analysis (IPA). Methods. Seven participants (three males, four females) who had undergone an AC in the United Kingdom took part in the study. Ages ranged between 26 and 41 years old at the time of interview. Time since AC ranged from 5 months to 4 years. Results. Participants appeared to be satisfied with, and tolerant of, the AC experience. Three superordinate themes: use of self-preservation strategies prior to and during AC, a bizarre yet pleasant operation experience, and the need for more concrete information prior to surgery were identified. These themes appeared to be embedded in a core theme: relationship with the neurosurgeon. Conclusions. The relationship with the neurosurgeon appears crucial to the patient experience of AC. This knowledge underscores the need for effective doctor–patient communication skills which could lead to improved delivery of care and more positive outcomes

Are Sitting Occupations Associated with Increased All-Cause, Cancer, and Cardiovascular Disease Mortality Risk? A Pooled Analysis of Seven British Population Cohorts

There is mounting evidence for associations between sedentary behaviours and adverse health outcomes, although the data on occupational sitting and mortality risk remain equivocal. The aim of this study was to determine the association between occupational sitting and cardiovascular, cancer and all-cause mortality in a pooled sample of seven British general population cohorts.The sample comprised 5380 women and 5788 men in employment who were drawn from five Health Survey for England and two Scottish Health Survey cohorts. Participants were classified as reporting standing, walking or sitting in their work time and followed up over 12.9 years for mortality. Data were modelled using Cox proportional hazard regression adjusted for age, waist circumference, self-reported general health, frequency of alcohol intake, cigarette smoking, non-occupational physical activity, prevalent cardiovascular disease and cancer at baseline, psychological health, social class, and education.In total there were 754 all-cause deaths. In women, a standing/walking occupation was associated with lower risk of all-cause (fully adjusted hazard ratio [HR] = 0.68, 95% CI 0.52-0.89) and cancer (HR = 0.60, 95% CI 0.43-0.85) mortality, compared to sitting occupations. There were no associations in men. In analyses with combined occupational type and leisure-time physical activity, the risk of all-cause mortality was lowest in participants with non-sitting occupations and high leisure-time activity.Sitting occupations are linked to increased risk for all-cause and cancer mortality in women only, but no such associations exist for cardiovascular mortality in men or women

The language of marketing hyperbole and consumer perception: the case of Glasgow

The aim of the study was to explore the potential of a timed word association task to generate detailed insights into the perception of Glasgow city and its people which could inform destination and brand marketing. Destination marketers have a challenge to convey the tourist destination image to attract and satisfy the expectations of its visitors. Yet destination perceptions are often the result of multiple tourist visitor experiences at a location, neglecting the voice of the resident. The extent to which word associations varied by participants’ relationship to Glasgow was identified in terms of Aaker’s brand personality scale, an extension of personality research on brands and destinations. Surveying of 1,219 UK participants generated a total of 5,993 terms (city; 1,144 unique) and 5,034 terms (people; 944 unique). The value of capturing the perceptions of a destination by its residents is identified. The results showed that the city of Glasgow was often described as cold and busy, while the people were primarily described as friendly and funny. Evidence was found in support of dual-processing theory suggesting word associations based on lived experiences of a city may be generated later (in terms of the order in which the terms were generated) in a word association task, while common linguistic associations (e.g. synonyms, antonyms, hierarchies etc.) tend to be generated earlier in the task. As hypothesised, analyses revealed a significant relationship between several of the Aaker-dimensions of brand personality, and the consumers’ relationship to Glasgow, extending marketing research with an empirical approach to identifying differences in the perceived personality of a destination. The study offers a practical, fast, and replicable method for destination marketers to study consumer perception at scale, which is currently not widely utilised in this field. In particular, the use of semantic distance and word embeddings provides a readily available approach to automatically categorise content derived from word associations studies, or indeed, any text-based content. In contrast, financial investment in non-validated branding and destination marketing campaigns appear to be increasingly problematic. Advances were made in testing an approach to interpreting word associations through the lens of linguistic and situated simulation (LASS) theory to provide deeper analysis to both categorise and interpret consumers’ perception. Traditional approaches to tourism marketing and destination branding rarely provide such a level of analytical appraisal. The analysis presented in this paper challenges the orthodoxy and validity of investment in brand and destination marketing at a city level and the potential for word association tasks to be used as a valuable alternative method to create more effective destination marketing and branding.<br/

The effect of cryotherapy and inflammation and myofiber regeneration following skeletal muscle injury

Cryotherapy is a widely used modality to treat acute skeletal muscle injury. Traditionally, cryotherapy is used immediately following an injury to accelerate the healing process by decreasing pain, inflammation and secondary hypoxic injury. Recent studies conflict with this long-standing practice and have suggested that cryotherapy may actually impair the myofiber regeneration process after muscle injury due to suppression of the inflammatory process. Therefore, delaying the healing process. A critical appraisal was conducted on three studies that have examined the inflammatory markers and markers of muscle regeneration. These studies were conducted over the past five years and have examined the effects of cryotherapy on inflammatory markers (mRNA levels of TNF-α, NF-κB, TGF-β and MMP-9), and myofiber regeneration (MyoD, IGF-1, platelet-derived growth factor (PDGF), vascular endothelial growth factor (VEGF), hepatocyte growth factor (HGF), brain-derived neurotrophic factor (BDNF), Desmin) after acute skeletal muscle injury. These studies found that cryotherapy suppressed inflammatory markers when compared to a control group. In addition, cryotherapy was found to either have no effect on myofiber regeneration or in the case of one study, it may delay skeletal muscle regeneration. In conclusion, these studies provide evidence that cryotherapy decreases the inflammation process which may lead to a delay in myofiber regeneration following skeletal muscle injury

Physical activity and Aboriginal and Torres Strait Islander People in Australia

Background Globally, non-communicable diseases (NCDs) such as cardiovascular disease and diabetes represent an issue of epidemic proportion, responsible for tens of millions of premature deaths annually. NCDs are also responsible for reducing quality of life and causing detrimental social and economic effects. Disparities across population groups are evident. In Australia, NCDs were a leading cause of the total burden of disease in 2011. Aboriginal and Torres Strait Islanders have a shorter life expectancy and poorer health risk factors and outcomes than non-Indigenous Australians. Much of this gap in life expectancy has been attributed to preventable NCDs. Physical activity is a key modifiable cause of the excess burden of disease and mortality. Among Aboriginal and Torres Strait Islanders, there is a lack of evidence around the associations between physical activity and health and demographic factors and the impact of strategies to increase physical activity, compared to mainstream evidence. Aims This thesis aims to contribute towards building an evidence base around the association of physical activity on the health of Aboriginal and Torres Strait Islanders. The first aim is to examine cross-sectional associations between physical activity and a range of lifestyle, environmental and social factors among adults. Subsequently, the thesis identifies and describes physical activity patterns and influencing factors among adolescents. The third aim is to describe characteristics of physical activity programs targeting Aboriginal and Torres Strait Islanders. Lastly, the thesis aims to measure the effects of a community-based physical activity program. Methods The series of studies used a range of methods. The first study examined whether achievement of national physical activity recommendations was associated with healthy lifestyle behaviours, neighbourhood environmental characteristics and social support among Aboriginal and non- Aboriginal adults in New South Wales (NSW) (Chapter 2). The second study examined cross-sectional demographic, social, psychosocial and health correlates of physical activity among Aboriginal and non- Aboriginal adolescents in NSW (Chapter 3). The third study examined age related declines in physical activity among Aboriginal and non-Aboriginal young people and their variation by season, setting and type among Aboriginal and non-Aboriginal children from between 2007/8 and 2011/12 (Chapter 4). The fourth study reviewed the scientific and grey literature for physical activity programs targeting Aboriginal and Torres Strait Islanders operating between 2012 and 2015, described their characteristics and engaged with program coordinators to verify sourced information (Chapter 5). The final study examined the health and community impacts of the Indigenous Marathon Program (IMP) in a remote Torres Strait island community, using questionnaire and semi-structured interview mixed methods (Chapter 6). Results In Chapter 2, a similar proportion of Aboriginal and non-Aboriginal adults achieved national physical activity recommendations and factors relating to achieving recommendations were similar in both groups. However, neighbourhood features and social support were less favourable among Aboriginal adults. Among Aboriginal and non-Aboriginal adolescents, physical activity levels were similarly low but some correlates differed by Aboriginality (Chapter 3). Aboriginal girls were less active than boys, as were those whose mothers were unemployed. In Chapter 4, serial physical activity declines were found in a population of Aboriginal and non-Aboriginal young people over five years, but not across all seasons, settings and types. Chapter 5, identifies 110 programs that aimed to increase physical activity for health or broader social outcomes. Around half were found to collect process or impact evaluation data but this is underrepresented in the scientific literature. In Chapter 6, impacts of Indigenous Marathon Program were the adoption of running and broader healthy lifestyle factors in a remote community with a high initial level of community readiness. Barriers to running were both personal, cultural and environmental. Conclusion The findings from this thesis make a novel contribution to building an evidence base of associations between physical activity and the health of Aboriginal and Torres Strait Islanders. A number of factors associated with physical activity in adults and children are unique to Aboriginal and Torres Strait Islanders populations; other factors are similar to those experienced by mainstream populations. It is vitally important that physical activity programs that aim to improve health or social outcomes can determine their value through evaluation

Facilitators and barriers to physical activity participation experienced by Aboriginal and Torres Strait Islander adults: A mixed methods systematic review protocol

Objective:To synthesize the existing research about physical activity and sport facilitators and barriers experienced by Aboriginal and Torres Strait Islander adults in Australia.Introduction:Physical activity and sport have cultural importance for First Nations peoples. Achieving health and broader benefits from physical activity and sport is impacted by experiences of both facilitators and barriers to participation. Identifying how to facilitate participation and overcome barriers to physical activity and sport is important to develop strategies to increase physical activity levels and sport participation among Aboriginal and Torres Strait Islander adults. Several studies have examined physical activity and sport facilitators and barriers experienced by Aboriginal and Torres Strait Islander adults, and collective synthesis of these studies can provide a more comprehensive understanding of their findings.Inclusion criteria:This mixed methods systematic review will consider studies that include Aboriginal and Torres Strait Islander peoples aged 18 years and over from any setting or region of Australia. Studies will be considered if they report on facilitators and barriers to physical activity and/or sport participation.Methods:Eleven databases will be searched, as well as gray literature sources, and a selection of websites containing resources relevant to physical activity participation for Aboriginal and Torres Strait Islander adults. Studies published in English will be included. No date limits will be set. After screening the titles and abstracts of identified citations, potentially relevant studies will be retrieved in full. Study selection, critical appraisal, data extraction, and data synthesis will be undertaken according to the convergent integrated approach to mixed methods reviews.Systematic review registration number:PROSPERO CRD42020162134

Comparison of free-living physical activity data obtained from a Fitbit Zip, the Apple iPhone Health app and a modified Bouchard Activity Record

Issue addressed: Physical activity tracking devices have potential to improve public health, but their data needs to be reliable. No study has compared movement data between the Fitbit Zip, Apple iPhone Health app and physical activity records in a community setting over 10 days. Methods: University students aged 18+ years wore both a Fitbit Zip and an iPhone at/near their right waist and completed a modified Bouchard Activity Record (BAR) for 10 days in a free-living setting. Comparisons were made between the Fitbit Zip and iPhone for the number of steps and the distance travelled and between the Fitbit Zip and BAR for the minutes of activity in three different intensities. Results: Eighteen students provided sufficient data for inclusion. There were strong correlations between steps per day (r =.87) and distance travelled (r =.88) between the Fitbit Zips and iPhones. However, the Fitbit Zip measured significantly more steps per day (mean 8437 vs 7303; P ≤.001) and greater distances (mean 5.9 vs 4.9; P ≤.001) than the iPhone. Correlations between the Fitbit Zips and the BARs were moderate for minutes of total (r =.51) and light (r =.40) activity and weak for moderate/fairly active (r =.20) and vigorous/very active (r =.25). Conclusions: There were strong correlations between the physical activity data measured by Fitbit Zips and iPhones, but the iPhone Health app significantly underestimated the number of steps per day taken and the distance travelled when compared to the Fitbit Zip. So what?: Understanding the comparability of accelerometer devices provides useful information for future pragmatic physical activity measurement
