Women face barriers to advancement in male-dominated fields (Glass Ceiling) and in female-dominated fields (Glass Escalator). More research is needed to elucidate the causes of these barriers in order to reduce the negative effects on women’s advancement. This study attempted to broaden the literature through the experimental examination of the glass escalator to further understand the gender inequalities that are seen in female-dominated fields. It employed a factorial design to examine the impact of gender, gender make up of an occupation, and level of authority within that occupation on a supervisor’s evaluation of an employee and decision to offer promotion, mentoring, and increase income and vacation time. Participants were recruited from Amazon Mechanical Turk and were just over half women, predominantly White and heterosexual, had a bachelor’s degree or higher, currently engaged in full-time employment, and half indicated their household income to be between $25,000 and $74,999. Each participant was presented with a single vignette of an employee file who was eligible for a promotion from a female-dominated (nurse), male-dominated (engineer), or gender neutral (accountant) occupation. They evaluated the employee’s performance and made recommendations for promotion, increasing raise and vacation days, and offered mentoring. Participants also completed the Gender Attitude Inventory (GAI; Ashmore, Del Boca, & Bilder, 1995) to better understand the role that gender attitudes play in gender bias in promotion decision-making. Multiple analysis of covariance was utilized to examine main effects and interaction effects of target employee gender, gender-type of occupation, and level of authority of the occupation. Hypotheses that men will be more likely to be promoted into positions with more authority, and women will be viewed as most competent in positions that are female-typed with the least amount of authority were not supported. Results showed that gender attitudes were weakly related to an employee’s performance evaluation, raise, and mentoring. Significant differences were found on the GAI where participants identifying as women, gay, and with a graduate degree had more liberal gender attitudes. Possible explanations for the predominantly insignificant results and future directions are discussed. Suggestions are provided for increasing the strength of the manipulation and factors that possibly decreased the salience of gender. Future experimental and continued qualitative studies in applied settings are recommended to identify causal influences of the glass escalator that examine factors of race, SES, and sexual orientation.

QC 351 A7 no. 03 / The problems connected with the utilization of large high -resolution telescopes are concentrated into two principal areas. The first concerns the physical properties of the mirror disc; the second involves the pro- cessing of the mirror in the optical shop. This technical report concerns, 1) the design of a new type of opti- cal polisher, one with a stationary mirror platform, and, 2) the casting of large discs made up of a new type of glass. This new glass, designated type RZ by Owens -Illinois, has a zero coefficient of thermal expansion at 25° Centigrade. A proposal for research in these two areas has already been made. This research has been supported, in part, under Contract ONR -2173- (12) by the Advanced Research Projects Agency and administered by the Office of Naval Research.

It is known that a newly formed glass container will only possess a very small fraction of its theoretical strength. This suggests that damage occurs on the surface of the glass melt during the forming process due to glass to mould contact and hot glass handling. It might be expected that any damage inflicted on the surface of a glass article during manufacture would heal at the elevated manufacturing temperatures used, however this does not appear to be true. Therefore, the actual mechanism by which glass strength is reduced during forming needs to be fully understood and the work presented in this thesis addresses this problem. Experiments, therefore, have been carried out here which simulate the formation of glass articles using an experimental pressing rig by systematically altering processing parameters such as the mould material, surface fmish of the mould, pressing temperature and atmosphere. Processing parameters that are used industrially for the formation of glass containers were generally reproduced wherever possible in order to investigate the glass-to-mould interaction. The interaction of both a cast iron mould material and carbon-carbon composite materials with a soda-lime-silica glass were examined using the techniques of scanning electron microscopy, x-ray photoelectron spectroscopy and atomic force microscopy in order to determine the type and extent of surface damage formed. The surfaces of the pressed glass samples made were found to contain defects of embedded particles and indented dimples. The embedded particles found were usually due to bulk material transfer from the plunger material used. The texture found on the surface of the pressed glass samples was found to be directly affected by the surface fmish of the plunger. Pressing glass samples using a cast iron plunger at an initial plunger temperature below 450°C resulted in a randomly rippled 'chilled' surface. As the initial temperature of the plunger was increased, the surface texture of the pressed glass became a closer replica of the plunger surface. The use of vacuum assistance to form the glass samples also resulted in the surface of the pressed glass becoming a closer replica of the original plunger surface, even at lower pressing temperatures. The surfaces of the cast iron and carbon-carbon composite plungers appeared to have been affected by the initial plunger temperatures used. As the initial pressing temperature was increased, the amount of oxidation for both material types increased. In the case of the carbon-carbon composite materials investigated, both the matrix and fibres were found to have broken down at the pressing temperatures used. X-ray photoelectron spectroscopy, of the pressed glass surfaces and the plunger materials indicated that sodium ions had migrated from the glass melt to the plunger surface during forming.

Although many texts discuss studio glass blowing in Australia, few focus on the South Australian situation and even fewer are written by studio glass blowers themselves. As a studio glass blower, I bring to this research experiential knowledge of practice to offer new insights into studio glass blowing. The study accesses knowledge that is implicit, embodied and tacit; knowledge derived from living and working within a particular community. In using this knowledge, I highlight the importance of both financial survival and the development of practice in creating a practitioner's perspective of studio glass blowing in South Australia. The study is designed as an ethnography. This incorporated a review of the literature and images found in published texts; interview and questionnaire data; anecdotal narratives and familiarity with the South Australian glass blowing community; and tacit knowledge of glass blowing practice, glass blowing skills and techniques. This tacit knowledge was accessed through an auto-ethnographic investigation of re-making the selected artefacts. The selection of these artefacts was based on my personal knowledge of glass blowing processes, first hand relationships with individual glassblowers, observation of artefacts and prior experience of working as a studio glass blower.
