description: The work presented in this thesis is an investigation of the dynamics of unconfined hydrogen-air flames in the presence of buoyant effects and the determination of an ignition criterion for flame propagation between adjacent pockets of reactive gas separated by air. The experimental work was conducted using the soap bubble technique and visualized with high speed schlieren or large scale shadowgraph systems. A study was first conducted to determine the most suitable soap solution additive among glycerol, guar and polyethylene oxide for conducting the experiments, isolating guar as the best candidate. The soap solution was then used to study the dynamics of flames in single or multiple soap bubbles filled with reactive mixtures of different compositions. The soap bubble method was also further improved by designing a soap dispenser that can maintain a bubble indefinitely and a method to burst the soap solution prior to an experiment using timed heated wires. In the experiments with single bubbles, it was found that for sufficiently lean hydrogen-air mixtures, buoyancy effects become important at small scales. The critical radius of hemispherical flames that will rise due to buoyancy was measured and estimated using a model comparing the characteristic burning speed and the rise speed of the flame kernel. Excellent agreement was found between the model predictions and the measured critical flame radii. The experiments with multiple bubbles provided the scaling rules for flame transition between neighboring pockets of hemispherical or spherical shape separated by an inert gas. The test results demonstrated that the separation distance between the bubbles is mainly determined by the expansion ratio when the buoyancy effects are negligible, corresponding to near stoichiometric mixtures. For leaner mixtures with stronger buoyant effects, the critical separation distance was no longer governed by the expansion ratio alone, as buoyancy forces render the flame propagation across the inert gas more difficult. Visualization of the ignition dynamics confirmed that buoyancy forces tend to accelerate the first kernel up before ignition of the second kernel can be achieved.
The relationship between body weight, body image, self esteem and relationship quality

description: The aim of the current study was to examine the relationships between body weight, body image, self-esteem and relationship quality in a community sample of obese, overweight and healthy weight individuals. It was hypothesised that as body mass index increased individuals would report greater body image dissatisfaction, experience lower self-esteem and perceive poorer relationship quality. A further prediction was self-esteem would mediate the relationship between body image and relationship quality. The sample consisted of 214 subjects, 162 were female and 52 were male, ages ranged from 18 to 72 years (M = 36.22 years, SD = 10.89 years). The participants anonymously completed a self-report questionnaire. The results supported the hypotheses, demonstrating a significant difference in the trends. This was significantly different for obese and healthy weight individuals, but not for overweight individuals. Future research using a larger sample size may assist in determining a difference. In addition, self-esteem mediated the relationship between body image and relationship quality. These findings support the idea obesity is indeed a complex condition that includes important psychological and psychosocial elements, which should not be overlooked when dealing with an obese individual.

description: Panic disorder (PD) is common in the community and contributes to significant distress and decreased quality of life for people who suffer from it. Most people with PD will present in the first instance to their general practitioner or hospital emergency department for assistance, often with a focus on somatic symptoms and concerns. This article aims to assist the GP to manage this group of patients by providing an outline of aetiology, approaches to assessment, and common management strategies. Although GPs have an important role to play in ruling out any causal organic basis for panic symptoms, the diagnosis of PD can usually be made as a positive diagnosis on the basis of careful history taking. Thorough and empathic education is a vital step in management. The prognosis for PD can be improved by lifestyle changes, specific psychological techniques, and the judicious use of pharmacotherapy.

description: Statement of the problem: Many methods for surrogate outcome validation require individual patient data which is often inaccessible by clinical trialists. Methods: A review was performed to identify statistical methods for surrogate outcome validation that may be implemented using summary data from published clinical trials. The methods were used to evaluate carotid intima-media thickness (CIMT) as a surrogate outcome for cardiovascular events in a systematic review of randomized trials of interventions for atherosclerosis. Results: the review of methods identified five procedures. At two or more years of follow-up, there was a marginally significant association of CIMT with myocardial infarction and a statistically significant association with cardiovascular mortality. At ≥ four years of follow-up, a statistically significant, negative relationship was observed between CIMT and stroke. Conclusions: CIMT may be a valid surrogate outcome for myocardial infarction and cardiovascular mortality. Additional data is needed to evaluate CIMT in specific drug classes.

description: Extracting the Electric Network Frequency (ENF) fluctuations from an audio recording and comparing it to a reference database is a new technology intended to perform forensic digital audio authentication. The objective of this thesis is to implement and design a range of programs and algorithms for capturing and extracting ENF signals. The developed C-program combined with a probe can be used to build the reference database. Our implementation of the Short-Time Fourier Transform method is intended for the ENF extraction of longer signals while our novel proposed use of the Autoregressive parametric method and our implementation of the zero-crossing approach tackle the case of shorter recordings. A Graphical User Interface (GUI) was developed to facilitate the process of extracting the ENF fluctuations. The whole process is tested and evaluated for various scenarios ranging from long to short recordings.

description: Infant word recognition is sometimes hindered by variability in the speech input. Previous research has shown that, at 9 months, monolinguals do not generalize wordforms across native- and accented-speakers (Schmale & Seidl, 2009). In the current study however, it was predicted that bilingual infants would be advantaged in accommodating for accented speech due to experience with phonetic variability across their two phonological systems. It was also predicted that this hypothesized ability would be restricted to accommodating for an accent derived from a familiar language (e.g., French-English bilinguals would accommodate for French-accented English but not Mandarin-accented English), since this type of variability would be consistent with the language sounds to which infants were regularly exposed. Study 1 set the experimental stage by identifying native and non-native speakers with similar voices, as perceived by a group of adults. This was done in order to restrict variability across speakers to differences in accent, rather than biological differences in voice (e.g., a higher or lower pitched voice). Following speaker selection, acoustic measurements of vowels and word stress placement were taken to compare native and non-native speakers and confirmed several expected deviations between native and accented speech. Study 2 tested the hypothesis that bilingual infants would be advantaged in accommodating for these deviations when the accent is derived from a familiar phonology. Using a headturn preference procedure (HPP), 9- and 13-month-old English-learning monolinguals and French-English learning bilingual infants were tested on their ability to recognize familiarized English wordforms across a native- and French-accented speaker. Bilinguals in both age groups succeeded in generalizing wordforms across speakers, however monolingual infants failed regardless of age. Study 3 tested whether bilinguals’ success would persist when the accented speaker’s first language was unfamiliar. Infants in this study failed as a group to generalize across native- and Mandarin-accented productions of English wordforms. However, bilinguals who received balanced exposure to their two languages performed better in accommodating for Mandarin accented speech than unbalanced bilinguals. This hints at a general ability to ignore irrelevant phonetic information, perhaps due to an advantage in cognitive control.

description: Current and future challenges such as the climate crisis, demographic change and achieving the objectives of the Water Framework Directive require holistic and precautionary approaches within the framework of national and supranational strategies. Specific measures and projects resulting from these strategic activities are required to successfully meet the challenges. In 2016, the German Environment Agency (UBA) and the Federal Ministry for the Environment (BMUV) commissioned the process for the development of the Federal Government's micropollutants strategy, which was later named the Trace Substance Strategy. The essential core instrument herein was a multi-stakeholder dialogue aimed at giving sufficient consideration to the different interests of the various stakeholders. The goal was to develop a balanced mix of measures and to initiate implementations in order to reduce emissions of micropollutants as effectively and efficiently as possible, at the source, in their application and in the downstream areas. The various measures were tested in a pilot phase, and the activities were evaluated before being transferred into the subsequent consolidation phase. This article describes the outcomes of the stakeholder dialogue as an instrument. This is complemented by the results of a stakeholder evaluation of the process itself and the results achieved. Important outcomes of the stakeholder dialogue are a Committee for the Identification of Relevant Micropollutants and the use of roundtables as an important instrument in which the manufacturers and the users of the substances can make an important contribution to reducing emissions. To address the opportunities and necessities of additional wastewater treatment, an "orientation framework" for municipal wastewater treatment plants was also established. Additionally, the German Centre for Micropollutants (SZB) was founded to continuously organize, support and accompany the various outcomes that became relevant pillars of the German government's Trace Substance Strategy. The evaluation has shown that new approaches and new instruments have been created within the framework of the stakeholder dialogue, which enable flexible and short-term options for action and allow for the involvement of stakeholders in a manner appropriate to the polluter-pays principle. Specific emission reductions could not be expected within the time frame of the dialogue. However, stakeholders agreed that the strategic process chosen is preferable to purely regulatory steps due to the holistic approach involving all stakeholders concerned in this complex matter. It is expected that in the future, if implemented consistently, the approach could achieve a lasting and sustainable impact on a broad scale. © 2023 by the authors

description: Background - Current guidelines suggest that all cancer patients with venous thrombosis be treated with long-term low molecular weight heparin. Whether treatment strategies should vary according to clinical characteristics remains unknown. // Systematic review - A systematic review was performed to determine current understanding of the association between malignancy characteristics in patients with cancer-associated VTE and the risk of VTE recurrence. Four retrospective and 6 prospective studies were included. They suggest that lung cancer, metastases, and adenocarcinomas confer an increased the risk of recurrence and breast cancer a low risk. // Survey - I performed survey to evaluate thrombosis experts’ opinion about the low risk of VTE recurrence they would consider acceptable for patients with cancer- associated thrombosis 103 specialists participated. 80% of respondents agreed that a risk of recurrent VTE during anticoagulation below 7% is low enough. 92% agreed that a CPR that categorizes risk of recurrence is relevant. // Retrospective Study - I performed a single retrospective cohort study to assess the feasibility of derivation of a CPR that stratifies VTE recurrence risk in patients with cancer–associated thrombosis. The study included 543 patients. A multivariate analysis selected female, lung cancer and prior history of VTE as high risk predictors and breast cancer and stage I disease as low risk. // Conclusion - Patients with cancer-associated thrombosis do have varying risks of recurrent VTE depending on clinical characteristics.

description: Networks are solid parts of the economic environment. The network success hypothesis predicts a positive relation between the networking activities of entrepreneurs and their economic success (Witt 2004, see Burt 2000). Surprisingly, at first glance, empirical research on networks and clusters offers quiet varying answers to the question if and why networks or clusters influence the development of start-ups positively. The motivation behind this paper is the question if and how cognitive phenomena should be taken under consideration analysing entrepreneurial networks and clusters. Therefore a general model of the interplay between single entrepreneurs and their networks will be developed.

description: Background The British Columbia Coroners Service implemented a policy in 2010 advising the reclassification of underlying causes of deaths due to falls from ’natural’ to ’accidental’. This study investigates whether observed data trends reflect this change in practice, are artefacts of inconsistent reporting, or indicate a true increase in fall-related deaths. Methods Mortality data were analysed from 2004 to 2017 for cases with International Statistical Classification of Diseases and Related Health Problems, 10th Revision fall codes W00–W19, occurring among adults aged 60 years and older. Results From 2010 to 2012, accidental fall-related deaths increased among those aged 80 years and older, followed by an increase in natural deaths with fall as the contributing cause. Conclusions Changes in reporting resulting from the 2010 policy change were observed; however, post-2012 data indicate a reversion to previous reporting practices.

Ces phénomènes sont étudiés dans le contexte des communautés dans lesquelles habitent ces individus franco-mobiles en s’attardant à l’effet du milieu défini en fonction de la proportion de francophones vivant dans la municipalité. Ces données sont analysées à travers une série de tableaux croisés. Les analyses révèlent que l’incidence de la mobilité sur l’appartenance et l’engagement est moins grande que postulée. Toutefois, elle a des conséquences plus importantes au niveau de l’engagement que de l’appartenance. Le milieu tempère puisque les effets de la mobilité diffèrent de façon notable, selon le type de communauté. C’est dans les milieux où les francophones représentent moins de 10% de la population que s’observe l’influence la plus marquée de la mobilité.

description: In agricultural watersheds, streams are intimately connected with croplands and may be inadvertently exposed to agrochemicals such as fertilizers and herbicides. Riparian plants and aquatic primary producers (aquatic plants, phytoplankton and periphyton) may be particularly affected by agrochemicals due to their taxonomic similarity to the intended targets (crop and weed species). The overall objective of this thesis was to assess the effects of fertilizers and the herbicide atrazine on riparian plants and aquatic primary producers. Effects were assessed across varying scales of observation ranging from empirical field studies at the watershed scale to in-situ experimental manipulations in two temperate streams to a laboratory concentration-response experiment. Twenty-four stream/river sites located across the South Nation River watershed, Canada ranged in surrounding agricultural land use (6.7-97.4 % annual crops) and in-stream concentrations of reactive phosphate (4-102 μg/L) and nitrate (3-5404 μg/L). A gradient of atrazine contamination spanning two orders of magnitude (56 d time-weighted-average concentrations of 4-412 ng/L) was observed using polar organic chemical integrative samplers (POCIS). A total of 285 riparian and aquatic plant species were identified with species richness ranging from 43-107 species per site. Atrazine and the percentage of surrounding annual crops had no statistically significant effects on community structure. In contrast, an increase in the percentage of non-native species, a decrease in submerged macrophytes and a decrease in overall floristic quality was observed along a gradient of increasing nitrate. Similarly, periphyton biomass increased with increasing nitrate across the watershed and was associated with the Chlorophyta. In contrast, no clear response was observed in periphyton exposed to nutrient enrichment and atrazine contamination in in-situ periphytometer experiments in two streams. Greenhouse concentration-response experiments provided evidence that the sensitivity of duckweed (Lemna minor) to atrazine was lower in populations previously exposed to the herbicide. However, the overall range in biomass 25% inhibition concentrations was small (19-40 μg/L atrazine). A clear gradient in agrochemical contamination was observed at the watershed scale and this research provided evidence of negative effects on riparian and aquatic primary producers. Effects of nutrients, specifically nitrate, superseded observable effects of the herbicide atrazine.

description: This dissertation explores and analyzes anti-imperial sentiments in Britain throughout the long eighteenth century. During this period of major British state formation and imperial expansion, there were a surprisingly large number of observers who voiced notable and varied concerns and opposition towards numerous overseas ventures, yet who have not since received significant attention within the historical record. Indeed, many critics of British imperialism and empire-building, from within Britain itself, formed extensive and thoughtful assessments of their own nation’s conduct in the world. Criticism ranged widely, from those who opposed the high economic costs of imperial expansion to those worried that a divine retribution would rain down upon Britain for injustices committed by Britons abroad. Such diversity of anti-imperial perspectives came from a clearly enlightened minority, whose limited influences upon broader public opinions had little effect on policies at the time. Successive British administrations and self-interested Britons who sought their fortunes and adventures abroad, often with little regard for the damage inflicted on those whom they encountered, won the political debate over empire-building. However, in the aftermath of the Napoleonic Wars, the perspectives of many of these individuals would increasingly become highly regarded. Later generations of reformers, particularly “Little Englanders”, or classical liberals and radicals, would look back reverently to these critics to draw inspiration for refashioning the empire and Britain’s position in the world. These eighteenth century ideas continued to present powerful counter-arguments to the trends then in place and served to inspire those, in the centuries that followed, who sought to break the heavy chains of often despotic colonial rule and mitigate the ravages of war and conquest.

description: The goal of this thesis is to improve our understanding of the Greenland ice sheet (GrIS) and how it responds to climate change. This was achieved using ice core records to infer elevation changes of the GrIS during the Holocene (11.7 ka BP to Present). The inferred elevation changes show the response of the ice sheet interior to the Holocene Thermal Maximum (HTM; 9-5 ka BP) when temperatures across Greenland were warmer than present. These ice-core derived thinning curves act as a new set of key constraints on the deglacial history of the GrIS. Furthermore, a calibration was conducted on a three-dimensional thermomechanical ice sheet, glacial isostatic adjustment, and relative sea-level model of GrIS evolution during the most recent deglaciation (21 ka BP to present). The model was data-constrained to a variety of proxy records from paleoclimate archives and present-day observations of ice thickness and extent.

S'appuyant sur l'étude de cas, la thèse a recueilli des données au moyen d'entrevues semi-structurées menées auprès de 14 participants recrutés dans quatre écoles de différents conseils scolaires francophones de l'Ontario. Les résultats ont révélé que la collaboration entre les enseignants avait joué un rôle de premier plan dans le cadre de leur démarche de pratique réflexive et que ce travail de collaboration avait mis en évidence certaines pratiques privilégiées par les enseignants pour contribuer à l'apprentissage de la littératie chez les garçons. On constate que les enseignants ont mis l'accent sur la diversification des ressources pédagogiques, l'utilisation de la technologie, le développement de la communication orale et la différenciation pédagogique. Les enseignants étaient unanimes pour dire que les pratiques pédagogiques mises en place à travers la pratique réflexive avaient amélioré l'attitude des garçons envers la littératie, surtout envers les activités de lecture, mais que ces pratiques n'avaient pas contribué à améliorer le rendement des garçons de manière systématique. En conclusion, cette recherche apporte une contribution importante du fait qu'il s'agit de la première étude effectuée sur la pratique réflexive en lien avec la littératie chez les garçons en contexte francophone minoritaire. L'étude permettra aux responsables des programmes et politiques scolaires de s'appuyer sur les résultats de la recherche afin d'élaborer de nouveaux programmes de développement professionnel et aux enseignants d'explorer certains aspects mis en évidence dans l'étude afin de mieux cibler leurs interventions en salle de classe.
Classifying excessive internet resource consumption: proposed taxonomies

description: The Internet’s current architecture de-couples the cost of sending traffic from the consequences of sending traffic. Its open nature allows anyone to initiate a connection with minimal authentication. These factors account for the excessive consumption caused by spam in the email system and other service areas. At the network layer, resource consumption caused by spam is analogous to Distributed Denial-of-Service (DDoS) attacks. We believe the two taxonomies proposed in this paper (of spam definition and of spam sending mechanisms) are the first comprehensive study of spam over different service areas. Our taxonomies will help in comprehending the similarities and differences between traditional Email spam and related newer problems such as SPIT (spam over internet telephony), SPIM (spam over instant messenger) and Web spam (spam over search engines, which misleads search engines into ranking some pages higher than they deserve).

description: Geothermal energy is an important source of clean and renewable energy. This project deals with the study of deep geothermal power plants for the generation of electricity. The design involves the extraction of heat from the Earth and its conversion into electricity. This is performed by allowing fluid deep into the Earth where it gets heated due to the surrounding rock. The fluid gets vaporized and returns to the surface in a heat pipe. Finally, the energy of the fluid is converted into electricity using turbine or organic rankine cycle (ORC). The main feature of the system is the employment of side channels to increase the amount of thermal energy extracted. A finite difference computer model is developed to solve the heat transport equation. The numerical model was employed to evaluate the performance of the design. The major goal was to optimize the output power as a function of parameters such as thermal diffusivity of the rock, depth of the main well, number and length of lateral channels. The sustainable lifetime of the system for a target output power of 2 MW has been calculated for deep geothermal systems with drilling depths of 8000 and 10000 meters, and a financial analysis has been performed to evaluate the economic feasibility of the system for a practical range of geothermal parameters. Results show promising an outlook for deep geothermal systems for practical applications.

description: Sexual violence is a prominent issue worldwide, especially during times of war and conflict. For refugee women, experiences with sexual violence are often incorporated in women’s reasons for forced migration. During the immigration process to Canada, refugee women are asked to share their narratives, at which point they may or may not disclose their histories of sexual violence. In June 2012, the Canadian government made substantial cuts to the Interim Federal Health Program. For refugee women who are survivors of sexual violence, this means that they are further limited in accessing services they might require in order to deal with the sexual violence they have experienced. Drawing from interviews we conducted with key informants (n=15) and refugee women (n=12) in both Toronto and Ottawa, this thesis explores both the lived experiences of refugee women and the changes, if any, that should be made to current service delivery. Our results show that there is a pronounced need for both small- and large-scale improvements at the systems and service delivery levels.

The limitations of the current approaches to housing provision in Kenya are discussed, along with their gendered implications. A review of the potential benefits which housing co-operatives provide for women is conducted. As part of this examination, a multi-scalar analysis of the housing co-operative sector in Kenya illuminates the role of gender mainstreaming policies and their role in addressing discrimination and inequality in the housing sector in Kenya. A case study of Rooftops Canada’s gender mainstreaming work in Kenya is used to provide examples of gender mainstreaming work being undertaken in the housing co-operative sector. This case study also provides insight into the role of international donors in gender equality work in Kenya’s housing co-operative sector.

description: Background: Travel time and healthcare financing are critical determinants of the provision of quality maternal health care in low resource settings. Despite the availability of pregnancy-related mHealth and smart travel applications, there is a lack of evidence on their usage to travel to health facilities for routine antenatal care and emergencies. There is a shortage of information about the feasibility of using a custom-made mobile technology that integrates smart travel and mHealth. This paper explores the feasibility of implementing a custom-made geographically enabled mobile technology-based tool (RoadMApp) to counter the adverse effects of long travel times for maternal care in Kwekwe District, Zimbabwe. Methods: We frame the paper using the first two steps (listen & plan) of the Spiral Technology Action Research (STAR model). The paper uses an exploratory case study design and Participatory Learning Approaches (PLA) with stakeholders (community members) and in-depth interviews with key informants (health care service providers, pregnant women, transport operators). One hundred ninety-three participants took part in the study. We conducted focus group discussions with pregnant women, women of childbearing age, men (household heads), and elderly women. The discussion questions centered on travel time, availability of transport, cellular network coverage, and perceptions of the RoadMApp application. Data were analysed thematically using Nvivo Pro 12. Results: Most parts of rural Kwekwe are far from health facilities and have an inefficient road and telecommunications network. Hence, it is hard to predict if RoadMApp will integrate into the lives of the community - especially those in rural areas. Since these issues are pillars of the design of the RoadMApp mHealth, the implementation will probably be a challenge. Conclusion: Communities are keen to embrace the RoadMApp application. However, the feasibility of implementing RoadMApp in Kwekwe District will be a challenge because of maternal health care barriers such as poor road network, poor phone network, and the high cost of transport. There is a need to investigate the social determinants of access to maternity services to inform RoadMApp implementation.

description: With over 65.3 million people of concern under the United Nations High Commissioner for Refugees mandate, the world is facing its biggest humanitarian crisis since the Second World War. The World Health Organization states that war and disasters have a large impact on a person’s mental health and psychosocial wellbeing, estimating that 5-10% of people who have experienced emergency situations suffer from mental health related problems. For refugee women in particular, research suggests that they have higher instances of mental health problems than other refugees which include depression, posttraumatic stress disorder, and anxiety. Using a scoping review methodology, this thesis examines the prevalence of refugee women’s mental health problems in the African context. It examines the experiences of these women living in African camps and the availability and accessibility of mental health services during their residency. Upon completion of the scoping review, the literature reveals that there is a high occurrence of mental health problems among refugee women residing in African camps. Furthermore, with relation to services it was found that varied mental health services are present but lack qualified personnel. Lastly, four themes emerged regarding refugee women’s experiences: violence, family life and losses, poor quality of life, and coping mechanisms.

description: Zinc oxide nanoparticles (ZnO NP) are often used in the food sector, among others, because of their advantageous properties. As part of the human food chain, they are inevitably taken up orally. The debate on the toxicity of orally ingested ZnO NP continues due to incomplete data. Therefore, the aim of our study was to examine the effects of two differently sized ZnO NP (<50 nm and <100 nm primary particle size; 123â€Ì614 mikromol/L) on two model systems of the intestinal barrier. Differentiated Caco-2 enterocytes were grown on Transwell inserts in monoculture and also in coculture with the mucus-producing goblet cell line HT29-MTX. Although no comprehensive mucus layer was detectable in the coculture, cellular zinc uptake was clearly lower after a 24-h treatment with ZnO NP than in monocultured cells. ZnO NP showed no influence on the permeability, metabolic activity, cytoskeleton and cell nuclei. The transepithelial electrical resistance was significantly increased in the coculture model after treatment with _307 _mol/L ZnO NP. Only small zinc amounts (0.07â€Ì0.65 mikrog/mL) reached the basolateral area. Our results reveal that the cells of an intact intestinal barrier interact with ZnO NP but do not suffer serious damage.

description: Parenting is a primary role for many young breast cancer survivors and the combined effect of parenting while coping with this disease can be problematic for many of them. Despite this, little is known about the impact of parenting on the well-being of young breast cancer survivors. This thesis, comprising two studies in article format, explores this question. In the first study, we identified elements of well-being that are salient for all young women with breast cancer, and which also captured some of the unique challenges associated with parenting as a survivor. Using factor analysis techniques, we determined how these elements interrelated in separate groups of young survivors with children and without, and identified differences between the two groups based on the patterns observed. We found that the interrelationship among elements of well-being varied between these two groups: psychological distress (representing mental health and perceived stress), illness intrusiveness, and fear of cancer recurrence were found to co-occur more frequently in mothers than in young survivors without children, thus compromising their well-being. Our second study had two objectives. The first part examined differences in perceived stress, illness intrusiveness, and fear of cancer recurrence between young breast cancer survivors with and without children in two separate timeframes (0-5 and 5-15 years since diagnosis). The second part identified predictors for these elements of well-being in young mothers exclusively. Compared to survivors without children, young mothers reported higher levels of fear of cancer recurrence and illness intrusiveness in intimate life domains during both timeframes, suggesting that disruptions in these areas persist over time. Part two revealed that mothers with adolescent children and high levels of parenting stress were most likely to report perceived stress and illness intrusiveness. A mother’s age and the time since her diagnosis predicted fear of cancer recurrence and illness intrusiveness, respectively. Results from this thesis indicate that young mothers with breast cancer need screening and interventions to manage psychological distress, fear of cancer recurrence, and illness intrusiveness, particularly in intimate life domains. This thesis also identifies the most vulnerable groups of mothers and has important implications for future research.
Out of mind out of sight, but we're not treating asylum seekers right

description: For a brief moment in 2008 asylum seeker advocates were optimistic. This moment of optimism has now gone. As the government announces plans to send newly arriving asylum seekers to Malaysia and also enters negotiations with PNG, it seems the only way is down. But things could be better, if we would just face facts.
