Gender Differences In Family Values: The Case Of Taiwan, Chia-Chi Cheng
Gender Differences In Family Values: The Case Of Taiwan, Chia-Chi Cheng
Sociology & Anthropology Theses - Archive
Marx claimed that the change of an economic base brings shifts to cultural organizations. Such shifts affect the social relations among different groups such as men and women. In order to ascertain whether gender differences in traditional family values exist in Taiwan, this study used the Taiwan Social Change Survey to identify the relationships associated with gender and traditional family values during periods of economic transition. The logistic regression and OLS regression findings of this study reveal that women are less likely than men to support traditional norms (i.e. coresidence, producing a male heir and gender roles). One very intriguing …

Interactions Between Antiwear Agent And Novel Additive In Engine Oils, Kajal Parekh
Interactions Between Antiwear Agent And Novel Additive In Engine Oils, Kajal Parekh
Material Science and Engineering Theses - Archive
Research has shown that side/end products of phosphorus and sulfur compounds in engine oils reduce effective life of exhaust catalysts of automobiles resulting in harmful emissions. Thus environmental regulations have been imposed on phosphorus levels in engine oils. The main source of phosphorus in today's oils is the indispensable antiwear agent Zinc Dialkyl Dithiophosphate (ZDDP). To find cost-effective non-phosphorus substitute has not proven fruitful. A unique way of reducing phosphorus or ZDDP level while maintaining good antiwear performance has been achieved by introduction of a novel additive FeF3 along with ZDDP. It appears that the interactions between FeF3 and ZDDP …

The envisioned tool can be divided into three main sections - the surgeon interface, the transmission mechanism, and the end effector. The surgeon interface mainly consists of a handle and two …
Parametric Cycle Analysis For Pulse Detonation Engines, Haider Hekiri
Parametric Cycle Analysis For Pulse Detonation Engines, Haider Hekiri
Mechanical and Aerospace Engineering Theses - Archive
The performance of an ejector-driven pulse detonation engine (PDE) with an afterburner is analytically estimated. In the analysis, the PDE was modeled as a straight tube, closed at the front end and open at the other. A detonation wave starts to travel after it is ignited at the closed end, causing a Chapman-Jouguet detonation wave followed by a Taylor rarefaction to travel to the open end. At that point, rarefaction waves are reflected back to the closed end. The result is a high thrust due to both the primary and secondary flows of the ejector-driven PDE. A theoretical analysis is …

Arc-Heated Gas Flow Experiments For Hypersonic Propulsion Applications, Christopher Matthew Roseberry
Arc-Heated Gas Flow Experiments For Hypersonic Propulsion Applications, Christopher Matthew Roseberry
Mechanical and Aerospace Engineering Dissertations - Archive
Although hydrogen is an attractive fuel for a hypersonic air-breathing vehicle in terms of reaction rate, flame temperature, and energy content per unit mass, the substantial tank volume required to store hydrogen imposes a drag penalty to performance that tends to offset these advantages. An alternative approach is to carry a hydrocarbon fuel and convert it on-board into a hydrogen-rich gas mixture to be injected into the engine combustors. To investigate this approach, the UTA Arc-Heated Wind Tunnel facility was modified to run on methane rather than the normally used nitrogen. Previously, this facility was extensively developed for the purpose …

Discharge Headway At Signalized Intersections In Monterrey, Nuevo Leon, Mexico, Luis F. Chapa
Civil Engineering Dissertations - Archive
Driver behavior has been the subject of study for almost 100 years. As a result, driver characteristics have been determined and used in the design of highway elements, both for interrupted and for free flow facilities. Signalized intersections represent the most typical interrupted flow facility, with driver reaction time and aggressiveness playing a key role in signal timing design and also in the assessing of intersection performance. These driver characteristics were first determined in the United States in the late 1940's, identifying an average headway (in seconds) between consecutive vehicles as they react to light change from red to green …

Management Dissertations - Archive
As the American workforce is buffeted by industries that are downsizing, requesting pay concessions and relocating production to foreign countries with lower factor costs, politicians and union representatives wave the flag of protectionism and explain the state of affairs in terms of a lack of national competitiveness. Porter (1990) links national competitiveness to the competitiveness of the nation's companies, asserting that this competitiveness is achieved through acts of innovation. According to the Small Business Administration (SBA), small business has become the dominant economic force in the United States again (U.S. SBA, 2000), producing 47 percent of all American sales, 51 …
Investigation Of Breast Tumor Hemodynamics By Near Infrared Spectroscopy: Applications To Cancer Therapy Monitoring, Jae Gwan Kim
Investigation Of Breast Tumor Hemodynamics By Near Infrared Spectroscopy: Applications To Cancer Therapy Monitoring, Jae Gwan Kim
Bioengineering Dissertations - Archive
Hyperoxic gas interventions using carbogen (95% O2 and 5% CO2) or oxygen has been tried to increase the tumor oxygenation since it will enhance the therapeutic effects on the tumors. Others in the laboratory had previously applied near infrared spectroscopy (NIRS) to monitor the changes in tumor blood oxygenation during hyperoxic gas intervention and found that oxyhemoglobin concentration changes (D[HbO2]) during gas intervention can be fitted by a two-exponential equation containing two time constants. Based on the model, they formed a hypothesis that changes in oxygenated hemoglobin concentration result from well perfused and poorly perfused regions of an animal tumor …

Duration And Depth: The Effects Of Leader-Follower Relationship Quality On Observer Ratings Of Leadership Performance, William David Rigdon
Duration And Depth: The Effects Of Leader-Follower Relationship Quality On Observer Ratings Of Leadership Performance, William David Rigdon
Psychology Theses - Archive
Previous research has shown that the duration and depth of the leader-follower relationship influences how followers rate their leaders. However, no studies were found that asked whether this relationship influenced how leader-supervisors rated leaders. This study investigated how the closeness (duration and depth) of the leader-follower relationship affected supervisor ratings. Based on previous research, this study expected to find a negative relationship between leader-follower closeness and supervisor ratings of overall performance, advancement potential and risk of career difficulty. Although the duration of the leader-follower relationship marginally supported this hypothesis, duration and depth together (closeness) did not.
