Every organism on Earth is exposed to ionizing radiation. Food, water, air, rocks, soil, medical procedures, building materials and, of course, ubiquitous background cosmic radiation contribute in varying levels and types of radiation to our total radiation exposure. In 1987 and 2006, the National Council on Radiation Protection, (NCRP) undertook the task of attempting to estimate the total annual background radiation to which humans in the United States are exposed. My research sought to verify the NCRP estimates using a series of coordinated measurements of gamma radiation from sea level to over 14,000 feet altitude taken at multiple locations in the Continental United States. With one exception on Pikes Peak, the actual data recorded were found to be lower than the data points predicted by the NCRP. This was the case even though the gamma spectrometer employed was demonstrated to be 124X more sensitive than existing devices. The observed variances from predicted levels ranged from a maximum of 2.1 millisievert to a minimum of 0.4 millisievert.

There is a growing political, academic and practical interest in refugee integration in Canada. The challenge, however, is that not much of the existing research focuses specifically on refugee women and their unique experiences beyond mental and physical health. My dissertation contributes to addressing this gap by examining their successes and challenges in the Canadian labour market. Using the 2016 version of the Longitudinal Immigration Database (IMDB), this dissertation addresses the question: What are the characteristics that predict economic success among refugee women in Canada? A secondary question asks, to what extent does arriving during an economic recession influence the income of refugee women? This dissertation uses Critical Race theory, Intersectional theory and Segmented Labour Market theory informed by a quantitative research design to address these questions. These theoretical perspectives help to understand the findings suggesting that the barriers in the Canadian labour market help to sustain existing racism, discrimination and inequality refugee women experience. The findings indicate that the level of education at arrival for refugee women in Canada varies. Based on the sample population in my dataset and existing research, there are large numbers of refugee women with low levels of education compared to those with graduate-level education and of those with university degrees. A significant number (62%), however, have skilled and technical education and work experiences prior to their arrival to Canada. In addition, the most dominant skill level among refugee women in Canada is elemental labour followed by intermediate labour and clerical skills. Very few refugee women (mainly those aged between 35 to 49 years) arrive in Canada with managerial and professional skills. Education is an important predictor of the employment income of refugee women in Canada according to the results of the multivariate analysis. The findings in this study, not sur

Using the 2016 Canadian census data, which is for the first time linked with administrative data on tax and immigration, this study examines the labour market outcomes of two groups of resettled refugees, Government-Assisted Refugees (GARs) and Privately Sponsored Refugees (PSRs), within a social justice framework. While previous research has focused on employment status and earnings, this study included occupational status as well to broadly assess the economic integration of refugees resettled in Canada. This study focused on four factors, gender, admission category, location of study, and age of arrival in Canada, which have received limited attention in previous refugee research. While existing research demonstrates the poorer economic outcomes of refugees compared to economic immigrants, the findings of subcategories of resettled refugees are descriptive, dated, and scant. My dissertation research reveals that nearly half of resettled refugees completed a postsecondary certificate, diploma, or degree, and over 65 percent of postsecondary graduates received their highest education in Canada. Yet, one third of resettled refugees were inactive in the labour market. While refugees are not admitted to Canada based on their financial or human capital, a considerable number of resettled refugees tended to seek self-employment instead of paid work. Refugee women were more disadvantaged in the Canadian labour market than refugee men. While PSRs fared better in finding a job and earned more than GARs, the picture is reverse regarding occupational status. A significant number of resettled refugees with foreign postsecondary credentials were working in low paying jobs, and the return on foreign university degrees was significantly lower than that on Canadian degrees. Age of arrival in Canada has an unanticipated association with employment status and employment income. My dissertation research offers new insights about the challenges and barriers that refugees face to acce

PurposeResearch indicates that lesbian, gay, and bisexual (LGB) adolescents are three times more likely to consider suicide than their heterosexual peers. Although research has identified risk factors for suicide among this population, little is known about school-level protective factors among this population, which may buffer the impact of risk.This study aims to understand whether school-based protective factors (e.g., school safety, relationships with caring adults at school, school connectedness) are associated with decreased suicidal ideation for LGB adolescents.MethodsLogistic regression analyses were conducted on the data generated by the San Francisco Unified School District's 2011 California Healthy Kids Survey to examine the influence of protective factors related to suicidal ideation for LGB adolescents (n = 356).ResultsResults indicated that higher levels of school connectedness predicted less suicidal ideation (odds ratio = .59, p =. 005).ConclusionsThis study provided evidence that school protective factors were related to reduced suicidal ideation for LGB adolescents, controlling for risk factors and demographic variables.

In_ the past, ~anaging employee performance and reward was a relatively uncomplicate~ affa1r. On the performance management side, it was a matter of requiring ~uperv1sors to assess each of their subordinates once a year using a simple rating scale mstrument, perhaps with a few management-imposed objectives included for good m~asure. On the remuneration side, the focus was on developing and maintaining a ~ob-based base pay and benefits structure d1at tempered external competitiveness wnh a degree of attention to internal equity. In the more complex traditional pay systems, there may also have been an element of individual performance-related reward perhaps in the form of assessment-based merit increments or one or other of the tradi: tiona! forms of payment by results, possibly co-upled with a modest level of coUective short-term incentives in the form of profit-sharing. Underlying all was an accent on the maintenance of a traditional top-down management culture, a mechanistic organisational structure and a stable relational psychological contract.

Six of seven US Navy Wasp Class (LHD) ships have 2500 KW Ship Service Turbo Generator (SSTG) steam turbine casings that were mistakenly manufactured with in-place first stage balancing holes in both the inboard and outboard sides of the upper casing half. These holes were intended for in-place balancing of the turbine rotor; however, the US Navy did not request the access holes since in-place balancing is typically not accomplished on in-service surface ship SSTGs. To correct the mistake, the OEM, developed a procedure to weld plugs into the holes. Unfortunately, cracks developed in the plug weld heat affected zones (HAZs) on many of the in-service units. Some cracks propagated entirely through the plug and leaked steam in service. A failure analysis determined that the original plug (Inconel X750) should have received post weld heat treatment (PWHT) to avoid embrittlement and the subsequent cracking of the HAZ. If PWHT was not to be accomplished, an alloy such as Inconel 600 should have been selected. It is noted that PWHT risks warping the casing and cannot be performed in-place. Inconel 600 repair plug installations we reperformed in-place, permitting a fast repair turnaround time, which allowed the affected ships to meet operational schedules. To evaluate the repair integrity, the US Navy reviewed the failure analysis data and repair procedure and performed a Finite Element Analysis (FEA) and Fracture Analysis. Various improved plug designs were also studied in parallel to determine if a different geometry plug would better resist future cracking. During repairs, minor radial cracks were discovered in the welding inlay originally installed between the casing and plug weld. Because the inlay had to be fully preserved to avoid complex and time consuming additional repairs to the casing including PWHT, minor cracks were left in place and consumed by the new weld. An important objective of this effort was to prove that if any cracking ever, The original document contains color images. Published in Proceedings of ASME Turbo Expo, 2012.

Whether voluntary or mandatory in nature, most recent corporate governance codes of best practice assume that board structural independence, and the application by boards of outcome-based incentive plans, are important boundary conditions for the enforcement of Chief Executive Officer (CEO) pay-for-firm-performance; that is, for optimal contracting between owners and executive agents. We test this logic on a large Australian sample using a system Generalized Method of Moments (GMM) approach to dynamic panel data estimation. We find that Australian boards exhibiting best practice structural arrangements - those chaired by non-executives and dominated by non-executive directors at the full board and compensation committee levels - are no more adept at enforcing CEO pay-for-firm-performance than are executive-dominated boards. These findings suggest that policy makers' faith in incentive plans and the moderating influence of structural independence per se may be misplaced. Our findings also hold significant implications for corporate governance theory. Specifically, the findings lend further support to a contingency-based understanding of board composition, reward choice and monitoring; an approach integrating the insights afforded by behavioural approaches to Agency Theory and by social-cognitive and institutional understandings of director outlook, decision-making and behaviour.

We present a deep ASCA observation of a broad absorption line quasar (BALQSO) PG 0946+301. The source was clearly detected in one of the gas imaging spectrometers, but not in any other detector. If BALQSOs have intrinsic X-ray spectra similar to normal radio-quiet quasars, our observations imply that there is Thomson thick X-ray absorption (NH ≳ 1024 cm-2) toward PG 0946+301. This is the largest column density estimated so far toward a BALQSO. The absorber must be at least partially ionized and may be responsible for attenuation in the optical and UV. If the Thomson optical depth toward BALQSOs is close to 1, as inferred here, then spectroscopy in hard X-rays with large telescopes like XMM would be feasible.

This paper examines the rise, hegemony and fall of the Barrier Industrial Council (BIC) in the mining town ofBroken Hill. Arguably, Broken Hill has been one of the few locations in Australia where the working class has established something like a hegemony. The BIC was the institutional force behind, and expression of, this control. The outlines of the BIC's role in Broken Hill are well known to many. This peak union body not only presided over a local system of collective bargaining largely outside the processes of compulsory conciliation and arbitration but, for many years, exercised a formidable control of local exchange and consumption as well as social relations more broadly.
