Harsh Reality is a print resource aimed toward the population of street-involved youth. Created by a working group of street-involved youth in partnership with a research nurse, Harsh Reality is a unique hybrid of factual information, and art and written experienced submitted by street-involved youth themselves. Harsh Reality contains information about a variety of topics, notably sexually transmitted infections and HIV/AIDS. A case study method was used to evaluate aspects of both project process and outcomes. The case study was guided by three areas of study: street-involved youth's perceptions of the resource, retention of specific knowledge outcomes from the resource, and method of resource distribution. The primary sources of data were street-involved youth themselves. Findings of this study include a description of the target audience's perception of the resource, an analysis of specific knowledge uptake, an assessment of various methods of resource distribution, and possible suggestions for future resources.

The spring bloom of microalgae within the bottom of sea ice provides a significant contribution to primary production in the Arctic Ocean. The aim of this research was to improve observations of the ice algae bloom using a transmitted irradiance technique to remotely estimate biomass, and to examine the influence of physical processes on biomass throughout the sea ice melt season. Results indicate that bottom ice temperature is highly influential in controlling biomass variability and bloom termination. Snow depth is also significant as it buffers ice temperature from the atmosphere and largely controls transmission of photosynthetically active radiation (PAR). The relationship between snow depth and biomass can change over the spring however, limiting biomass accumulation early on while promoting it later. Brine drainage, under-ice current velocity, and surface PAR in the absence of snow cover are also important factors. Overall this research helps to characterize the spring ice algae bloom in the Arctic by improving in situ biomass estimates and identifying primary factors controlling it.

Background: Contracting asexually transmitted disease is strongly associated with stigmaand shame. Stigma associated with these diseases has a significant impact on self-image andpropensityto seek care. Despitehigh incidencethere is a generallack of awareness about therisks and theeffectsthatthese diseases have on both mental and physical health. Health carepersonnel are experiencing difficulties to meet and care for these patients. Aim: The aim ofthis studyisto describe patients'experiences of health care after they were diagnosed with asexually transmitted disease. Method: The study was conducted as a systematic literaturereviewbased on tenoriginal articles. Ameta-synthesiswas used for the analysisandthe resultwasdiscussedwithHalldórsdóttir's (1996) theory;"Caring and Uncaring Encounters inNursing and Health Care–From the Patients Perspective". Result: Five themes emerged;The importance of emotional support;Beingjudged by the health personnel; The importanceof information;To (not) talk about sexandThe environmentalimpact on the confidentiality.Conclusion:Patients with sexually transmitted diseasesare experiencingencounters withhealth care bothnegativelyand positively, although there were mostlynegative experiencesofthe encounters. Several factors affect patients' experiences.Encounter with health care affectspatients' well-being and health. Clinical significance: The knowledge fromthis studymightenable a patientcentredapproach. Based on this knowledge,healthcouldbe developed so thatthe encounter itselfpromotesempowerment and an increased sense of well-being and health. / Bakgrund: Att få en sexuellt överförbar sjukdom är tydligt förknippatmed stigma och skam. Stigma har en betydande påverkan på individens självbild och benägenhet att testa sig. Trots hög incidensidentifieras en generellt bristande medvetenhet om de risker och effekter dessa sjukdomar har påbåde psykisk och fysisk hälsa. Vårdpersonal upplever svårigheter att bemötapatienter med sexuellt överförbara sjukdomar. Syfte: Studiens syfte är att beskriva patientersupplevelser av mötet med vården efter att de diagnostiserats meden sexuellt överförbarsjukdom. Metod: Studien genomfördes som en systematisk litteraturöversikt där tio originalartiklar sammanställdes med en metasyntes och diskuterades utifrån Halldórsdóttirs (1996) teori;"Vårdande och icke-vårdande möteni omvårdnad och hälso-och sjukvård–utifrån ett patientperspektiv". Resultat: Fem teman framkom som återkommande upplevelser; Betydelsen av emotionellt stöd; Att bli dömd av vårdpersonalen, Betydelsen avinformation; Att (inte) tala om sex och Den fysiska miljöns påverkan på konfidentialiteten. Slutsats: Patientermed sexuellt överförbara sjukdomar upplever mötet med vården ivarierande grad negativt och positivt. Dock framkom det övervägande negativa upplevelser av mötet. Flertalet faktorer påverkar patienternas upplevelse. Mötet med vården påverkar patienternas välbefinnande och hälsa. Kliniskbetydelse: Kunskapen från resultatet i denna studie kan möjliggöra en patientcentrerad vård. Utifrån resultatet kan vården utvecklas så att mötet upplevs som vårdande, och där mötet i sig samt kontakten med vården skapar egenmakt och en ökad känsla av välbefinnande och hälsa.

Persistent infection with certain subtypes of Human papillomavirus (HPV) is a necessary cause of cervical cancer, the second most common cancer among women worldwide. Uptake of HPV vaccines in the targeted Canadian female population has been lower than anticipated. This study’s primary objective was to determine undergraduate women’s perceptions about HPV vaccination. A total of 401 female University of Ottawa undergraduate students completed a newly developed cross-sectional web survey. The prevalence of HPV vaccination was 49%. While the overall attitude towards receiving the vaccine was positive, vaccinated respondents had more favorable attitudes toward the vaccine. Lack of vaccine knowledge and cost were the primary barriers that have prevented HPV vaccination among non-vaccinated respondents. Offering HPV vaccination for women aged 18 to 25 presents a strategy for addressing suboptimal vaccination coverage in the targeted female population and may reduce health inequities demonstrated by variations in cervical cancer incidence within jurisdictions.

For low data rate ultra-wideband (UWB) communication systems employing non-coherent detection and autocorrelation detection schemes, timing of integration region significantly affects their error rate performance. Time-of-arrival (TOA) estimation of the first channel tap is also the foundation of the UWB based ranging applications. In this thesis, a data-aided, autocorrelation based timing and synchronization method is developed. First, estimation of the optimal integration region, i.e., the initial point and the length of the integration, using the new timing method is presented. It is shown that the proposed method enhances the error rate performance compared to non-optimal integration region-determining methods. After that, TOA estimation using the proposed timing method is studied for the dual pulse (DP) signal structure. The performance improvement of this approach over the conventional energy detection based method is demonstrated via simulation.

The purpose of this study was to describe the sexual health knowledge and attitudes of a sample of Saskatchewan post secondary freshmen aged 17-19. Three primary questions guided this research: What do Saskatchewan freshmen know about the general sexual health topics of physiology, contraception, and sexually transmitted infections? What are common attitudes about sexual activity, risk behaviors, and relationships? What were the main sources of sexual health information for these freshmen, and do they express a need for more education and resources? The study design was a qualitative web-based survey. Participants were volunteer freshmen aged 17-19 from the University of Saskatchewan and Saskatoon Institute of Applied Science and Technology, and 515 responded. Sixty-two percent were sexually active. Condoms were seen as helpful (98%) but only 57% saw them as effective for preventing pregnancy. Only 47% saw condoms as effective for preventing HIV/AIDS. Knowledge of reproductive physiology and STI symptoms and consequences were low with an average knowledge score of 26%, while HIV and AIDS knowledge scores averaged 80%. Knowledge of long acting contraceptives was much lower than birth control pills. Human papilloma virus was poorly understood, and many wanted more information about HPV vaccination. Attitudes were mixed about safe sexual activities, with respondents identifying condoms (94%), withdrawal (18%) and anal sex (15%) as safer sex. Condoms were used at last intercourse by 57%. A variety of attitudes were expressed about condom use, sex in relationship, and social pressures. Topics concerning to respondents were sexual violence, HIV/AIDs, STIs, unintended pregnancy, and the influence of alcohol/ drugs on sexual activity. Very few respondents had heard of or accessed sexual health websites designed and promoted to teens. An interest was expressed for more information from doctors and public health nurses, more guest speakers for SBSHE, and easier access to sexual health clinics. The information gathered in this study highlighted many areas for further detailed inquiry, and topics that can be better addressed in physician’s offices and sexual health curriculum. Additionally, the results could guide sexual health educators, policy makers and direct physicians towards collaboration and advocacy projects, and ultimately contribute to long term improvement in sexual health of Saskatchewan teens.

<p>Curricula should be strengthened by teaching the curability of STIs and the importance of STI treatment to prevent HIV transmission. This study focused on the control of sexually transmitted infections as a key HIV prevention strategy. Sexually transmitted infections act as a strong cofactor in the sexual transmission of HIV. Effective STI management can limit the spread of HIV.</p>

Introduction: Oil/gas communities across Northeastern British Columbia are experiencing rapid in-migration of young, primarily male workers in response to an economic ‘boom’ in the oil/gas sectors. Accompanying the ‘boom’ has been a rise in rates of sexually transmitted infections (STIs) among young people, with Chlamydia rates among youth in the Northeast exceeding the provincial average by 22%. Previous research indicates that socio-cultural and structural determinants of youth sexual behaviour and access to STI testing are important for understanding youth sexual health disparities – and represent key targets for STI prevention efforts. No other research has explored STIs in this rapidly developing, under-resourced context. Therefore, objectives of this thesis were to: (1) Examine how socio-cultural and structural features related to the oil/gas ‘boom’ affect the sexual behaviour of young people in Fort St. John (FSJ), BC; (2) Gather the perspectives of youth and their service providers on the socio-cultural and structural barriers to STI testing in FSJ; (3) Develop recommendations to improve the accessibility of STI testing. Results: Participants identified 4 main ways in which the socio-cultural and structural conditions created by the ‘boom’ affect sexual behaviours, fuelling the spread of STIs in FSJ: mobility of oil/gas workers; binge partying; high levels of disposable income; and gendered power dynamics. As well, 5 key barriers to STI testing among youth were identified: limited opportunities for access; geographic inaccessibility; local social norms; limited information; and negative interactions with providers. Discussion: These data indicate that the conditions fostered by the ‘boom’ in FSJ exacerbate sexual health inequalities among young people. They can be more widely contextualized as an example of the unintended – but not unexpected – health and social implications of a resource-extraction ‘boom’, illustrating the fallacy of ‘development’ as representing uniformly positive ‘progress’. Recommended actions include STI prevention and testing service delivery models that incorporate a locally tailored public awareness campaign, outreach to oil/gas workers, condom distribution, expanded clinic hours and drop-in appointments, specialized training for health care providers, and intersectoral partnerships between public health, non-profit organizations, and industry. An ongoing knowledge translation internship has been undertaken to implement some of these recommendations.
