The purpose of this study was to explore the phenomenon of community colleges creating pathways to degree completion in professional-technical programs by breaking degree programs into smaller portions, referred to as "chunks." The purpose or possible advantage of chunking was that it would improve the rate of degree completion among...
Community colleges are experiencing a decline in state allocated funding. Traditionally, college administrators look for ways to cut expenditures and raise tuition and fees to make up for the shortfall. Using available land resources to generate a revenue stream may provide revenue for community colleges.
The purpose of this study...
Traditionally linear actuator applications are addressed by the use of hydraulic systems. The high maintenance cost and poor reliability will always be the most critical problem in the real applications. Benefited from both the high mechanical advantage of the roll screw and the simple structure of the switched reluctance motor,...
The purpose of this study was to examine the problem solving processes of
Thai gifted students when they solved non-routine mathematical problems. The
research questions guiding the study were: (1) What is the nature of the problem
solving processes that Thai gifted students use as they engage in solving non-routine...
Twenty-six Holstein and 18 Jersey multiparous cows in a randomized block design were assigned by calving date and breed to a non-anionic prepartum diet (CTRL) or a treatment diet containing a commercial anionic salt supplement (Animate®). Control and treatment diets were formulated to a dietary anion-cation difference (DCAD) of 21.3...
The purpose of this study was to describe the development of mathematics
preservice teachers’ technology pedagogical content knowledge (TPCK) in a
subject specific, technology integrated teacher preparation program. The study also
investigated the roles of several influential components of the program and the
technology thread throughout the program in supporting...
This study examined the validity of the WA PPA process which was developed to assess teacher candidates for licensing purposes. Three validities were investigated using Messick’s view. Content validity was addressed using the raters’ judgment to
establish alignment between the WAC standards and the INTASC. Evidential validity refers to the...
Ultra-wideband (UWB) communication has emerged as a very promising
technology for short-range wireless applications, including
high-speed multimedia transmissions and sensor networks. UWB
system designs involve many different aspects covering analog and
digital processing, channel estimation and modeling, and
modulation and demodulation. Although UWB still faces many
challenges, significant progress has...
Four studies were conducted on late-summer diet quality and quantity of cattle (Bos taurus), mule deer (Odocoileus hemionus hemionus), and elk (Cervus elaphus) in response to prior grazing by cattle and elk on mixed-conifer rangelands and on related research techniques. In our first study we assessed a photographic technique to...
This dissertation addresses issues of oligopoly markets where advertising plays a prominent role. The first study empirically investigates the effect of advertising regulations on equilibrium consumption of an addictive commodity using U.S. cigarette industry data. The results of the first study show that the advertising regulations reduced cigarette consumption by...
