Prior to the 1930's, little thought was
given to planning for retirement.
Today, retirement planning is built
into employment through social security
and retirement plans so that even
the young employee becomes aware of
retirement and begins making financial
contributions as soon as he starts his
working career. However, it...

The basic objective of this thesis was to estimate the
economic effects of yield grade standards for carcass beef
on the various market sectors of the Canadian beef industry.
The adoption of the standards was expected to enhance
consumer demand, improve efficiency within the processing

There is considerable evidence to support the
hypothesis that seafood, poultry and meat are close
substitutes in consumer demand. Thus the relationships
among prices are important in determining consumption
patterns among these protein sources. In addition, there
are at least two kinds of outlets in which seafood, poultry
and meat...
Mounting inflationary economic pressures and the obvious spiralling costs of education, at all levels, has drastically augmented public, administrative, and government concern regarding the effectiveness of many educational training programs. Secretarial Science, which is designed to provide occupational-level training represents such a program. Therefore, this study was conducted in order...
Individuals with mild developmental disabilities have
traditionally been excluded from full participation in
their career decision making due to the stereotyping of

Deforestation and loss of soil fertility are two forms of environmental degradation with global importance. Theories of environmental degradation commonly cited in public and academic discourse have historically emphasized the role of human populations and national economic development as being the primary drivers of environmental damage. This thesis utilizes quantitative...
In resource constrained settings, missing markets and unregulated externalities can have a significant impact on human capital outcomes. High out of pocket expenditure due to the inaccessibility of insurance markets limits the use of healthcare, just as the inability to borrow in the face of a cash constraint may lead...
Union density in the United States has declined to historic lows over the past four decades. In 1954, nearly 35 percent of workers were union members while only 11 percent of workers were members of unions in 2015. Simultaneously, economic inequality widened, with one-third to one-fifth of this increase attributed...
Improving access to and uptake of antenatal care remains a persistent challenge for India. It is a far greater challenge for an underdeveloped, poorer and mostly rural state like Bihar. The 2015-16 National Family Health Survey (NFHS-IV) of India reported that only 3% pregnant women in rural Bihar utilized full...
The 2010 U.S. health reforms expanded health insurance access to millions of Americans, mainly through an unprecedented expansion of Medicaid eligibility to those with low incomes. Not all states chose to expand their programs, resulting in disparate health-benefit access nationally. This study uses quantitative and qualitative analyses to explore the...
Bird and bat collisions with wind turbines are a problem that needs to be better quantified for its impact to be fully understood. This thesis documents portions of the design of a sensor patch module for use on wind turbines blades to detect impacts caused by birds and bats. This...
Microfluidics is an evolving field that focuses on the manipulation of small fluid volumes. Because of its micron-sized features, it is the basis for many lab-on-chip and point-of-care diagnostic devices. The devices are predominantly molded from polydimethylsiloxane (PDMS); however, production is a multi-hour or multi-day process that typically requires clean...
Pulse Oximetry is a technology used ubiquitously across the medical field for measuring oxygen saturation and heart rate monitoring.

My work on computing complex catalyzed organic transformations reveals that only a few subtle chemical factors, e.g. non-classical hydrogen bonding, (hyper)conjugation and steric effects, common across different catalyst manifolds are critical for catalysis and selectivity. Rational manipulation and exploitation of these factors has led to improved catalyst designs, which has...
Designation of areas as marine wilderness has been proposed as a strategy for managing the increasing threats facing the world’s oceans. Although social factors influence marine protected area success, the human dimensions of marine wilderness remain minimally explored. This thesis examines views of marine wilderness expressed by a representative sample...
The climatic and tectonic framework of the St. Elias orogen makes it an excellent place to study the interactions between tectonic processes such as deformation and erosive processes, in particular glacial erosion. One type of link between these processes, proposed by numerical models of orogenic development, is an effect of...
The application of modern land management practices beginning at the turn of the 20th century is widely believed to have dramatically transformed forest landscapes of the inland Pacific Northwest.

I studied small-mammal communities and their response to grazing in mixed-conifer forests and oak woodlands in the Cascade-Siskiyou National Monument in southern Oregon. My objectives were to (1) compare small-mammal communities among forest types and grazing intensities, (2) identify riparian affiliated species, and (3) describe microhabitat associations. Over two years,...
Chemically defined liquid media were devised which supported
excellent growth of Taphrina cerasi and T. deformans. When grown
in fermentation culture vessels, T. cerasi and T. deformans released
cytokinins into the liquid media. The presence of these cell division
factors was demonstrated with the soybean tissue assay which is
specific...
Public sector unions push for unmerited wage increases, exacerbating inflation and deficits. Despite this conventional wisdom, governments in several European countries successfully limited public sector wage growth during the 1980s and 1990s. It is argued in this paper that the recent rise in public sector wage inflation in the Euro-zone...

Dense electrical recording of biosignals has been developed to provide spatial resolution and precise temporal information for health monitoring, diagnostics, and clinical research. However, more electrodes require more wires, and wiring density quickly becomes a limiting factor. To break this bottleneck, we proposed a frequency-division multiplexing (FDM) based architecture for...
Low-power receivers (RX) with 100$\mu W$-scale power consumption can enable several power/energy-constrained IoT applications. However, achieving sensitivity, interferer tolerance and wide operating range with low power presents a challenge for existing architectures, particularly those constrained to highly integrated solutions without high-Q off-chip components. Existing solutions rely heavily on high quality...
Flow rate sensors for in situ gas or liquid monitoring typically comprise multiple transducer elements, including a heater and one or more temperature sensors to measure the rate of heat energy removal by the flowing fluid. The need for multiple transducer elements limits feasibility of shrinking these sensors to microfluidic...
