Pthreads Profiler, Ryan Van Quinlan

Computer Science and Software Engineering

The goal of this senior project was to design and implement a program which would allow users to profile programs that utilize the Pthreads library. This profiler allows users to measure load balance and lock contention between threads as well as discover deadlocks. These tools can be essential to developers of multi-threaded applications, which are notoriously difficult to debug. Additionally, this tool can help find vital performance benefits by providing relative execution measurements. The profiler is written in C++ and utilizes the standard template library as well as glibc extensions.

Nonproliferation: Rapid Retreat From The Gold Standard Negatively Impacts Future Nuclear Negotiations, Evan Tyler Beese

Graduate Theses/Dissertations

In 2009, the United States and the United Arab Emirates (U.A.E.) concluded a nuclear cooperation agreement which contained a commitment on the part of the U.A.E. not to enrich uranium through its own domestic programs. Dubbed the "Gold Standard” of nuclear nonproliferation by the Obama administration, such an accomplishment has not been repeated in nuclear agreements between 2009 and 2015. This paper examines American nuclear cooperation negotiations following the establishment of the "Gold Standard,” and argues that the rapid reversal of American negotiating policy toward enrichment and reprocessing technologies will hinder U.S. nonproliferation goals going forward.

Systemic Insulin Sensitivity And Skeletal Muscle Akt Signaling In Rats Artificially Selected For Low And High Aerobic Capacity, Kyle Levi Fulghum

Graduate Theses/Dissertations

The mechanism(s) linking physical inactivity, obesity, and type-II diabetes are unclear. I hypothesized low intrinsic aerobic capacity is associated with reduced systemic insulin sensitivity via skeletal muscle insulin signaling. After 34 generations of selective breeding, high aerobic capacity (HCR) rats exhibited an 8-fold increase in running distance vs low aerobic capacity (LCR) rats (n=14 per group). LCR rats had higher rates of weight gain vs HCR (p<0.05) though food consumption was constant (p=0.86) over a 12-week study. Rats were divided into 4 groups: 1) LCR-Sham Surgery, 2) LCR-Catheterization, 3) HCR-Sham Surgery or 4) HCR-Catheterization (n=7 per group). Euglycemic-hyperinsulinemic clamps on catheterized rats tested insulin sensitivity while sham LCR and HCR were used for basal tissue analysis. Plasma insulin levels did not differ during the clamps, but LCR required lower glucose infusion rates than HCR (p<0.05). Upon insulin stimulation, both absolute and normalized phospho-Akt(Ser473) of soleus muscle were significantly increased in HCR above basal group (p<0.05), but not in LCR. No difference was observed between insulin-stimulated phospho-Akt(Ser473) of HCR and LCR groups . These data support that LCR is linked to a reduction in insulin sensitivity in vivo without impairments of insulin-stimulated skeletal muscle phospho-Akt(Ser473) vs HCR rats.

Development Of A Set Of Force Response Equations To Represent The Musculature In Infants To Study Development Dysplasia Of The Hip, Brendan Jones

Probation Officer Roles: A Statutory Analysis, Ming-Li Hsieh, Moana Hafoka, Youngki Woo, Jacqueline Van Wormer, Mary K. Stohr

Criminal Justice Faculty Publications

There are a limited number of studies that explore the legally prescribed roles of probation officers. To address this, the current study employed a statutory analysis to examine how probation officer roles have changed over the past 30 years, identifying which tasks and roles are statutorily mandated for probation officers. Findings indicate that there is an emergence of a "case manager" approach in the legally prescribed roles for probation officers in many states, even though law enforcement-oriented tasks are slightly more prescribed by law than rehabilitation-oriented tasks.

Happiness In Modern Society: Why Intelligence And Ethnic Composition Matter, Satoshi Kanazawa, Norman P. Li

Research Collection School of Social Sciences

Recent developments in evolutionary psychology suggest that living among others of the same ethnicity might make individuals happier and further that such an effect of the ethnic composition on life satisfaction may be stronger among less intelligent individuals. Data from the National Longitudinal Study of Adolescent Health showed that White Americans had significantly greater life satisfaction than all other ethnic groups in the US and this was largely due to the fact that they were the majority ethnic group; minority Americans who lived in counties where they were the numerical majority had just as much life satisfaction as White Americans …

The Rates Of Mothers Who Continually Breastfeed After Implemented Breastfeeding Teaching, Katherine L. Moore

The Eleanor Mann School of Nursing Undergraduate Honors Theses

Many mothers are unaware of the benefits of breastfeeding. This lack of knowledge leads to an inability to weigh the advantages and disadvantages of the potential source of nutrition their infant will receive during his or her first months of life. Many mothers never even attempt to breastfeed their infant. Even among the mothers who do initially choose to breastfeed, the majority deviate to other forms of feeding early in the postpartum period. Despite the fact that most major medical organizations encourage exclusive breastfeeding through the first six months of an infant’s life, the CDC report for 2013 claims the …
