Bio-Socially Inspired Strategies In Support Of Dynamic Spectrum Access: An Evolutionary Game Theory Perspective, Mohammad Ali Marzoug Abu Shattal

Dissertations

Dynamic Spectrum Access (DSA) has been introduced to fulfill the expanded need for spectrum by different wireless networks and applications. Within the realm of spectrum access, the problem of "spectrum crunch" is present since some of the spectrum bands are overcrowded and others are underutilized. DSA aims to alleviate the problem of spectrum crunch. In DSA, Primary Users (PUs) allow Secondary Users (SUs) to access the spectrum as long as they do not interfere with PU transmissions beyond a pre-agreed acceptable level. In this work, a bio-socially inspired approach is proposed for SU interactions in support of better throughput for …

Modelling The Impact Of National Development Strategies For The East African Rice Sector, Florence Muthee

Graduate Theses and Dissertations

The 2008 food crisis prompted many food importing nations to reconsider the need to be self-sufficient especially in their staple food needs. This awakening led to the launch of the Coalition for Africa Rice Development (CARD) initiative with a goal to double rice production in Africa. Under the CARD umbrella member countries drafted individual National Rice Development Strategies (NRDS). This study is a quantitative assessment of four East African countries’ NRDS: Kenya, Rwanda, Tanzania and Uganda within dynamic global rice economy models. The NRDS targets and strategies are not realistic and included under estimation of rice consumption for Kenya, an …

Effects Of Pre-Chiller Temperature On The Microbial Ecology Of Whole Bird Carcass Rinses, Rachael Elizabeth Blevins

Graduate Theses and Dissertations

Upon entering a poultry processing facility, birds are already contaminated with a variety of microorganisms. It is the responsibility of the processor to reduce these numbers to deliver a wholesome product to customers. This is not an easy task as there are ample opportunities for further microbial contamination. Some of these opportunities are obvious. For example, any areas where contaminants could be washed off one bird and onto another are always an area for concern, i.e. the scalder or the chiller. There are numerous opportunities for contamination that are not so obvious. These incidents of contamination are not necessarily due …

The Cold War In The Eastern Mediterranean: An Interpretive Global History, James M. Brown

Graduate Theses and Dissertations

This thesis offers the first global history of the Cold War in the eastern Mediterranean. It examines the international linkages that bound Greece, Turkey, and Cyprus with superpowers, non-aligned states, and transnational movements during the second half of the twentieth century, and it considers the effects of such linkages upon the eastern Mediterranean’s domestic arenas. Throughout, it demonstrates that two forces – synthesis of outside influence alongside consolidation of internal identities – dictated the region’s experiences during the Cold War. And though the international environment furnished the conditions within which the region’s societies pursued the project of nation-building, indigenous forces …

Population Dynamics Of Ouachita Dusky Salamanders (Desmognathus Brimleyorum) In A Managed Forest Landscape, Kelly Marie Halloran

Graduate Theses and Dissertations

With anthropogenic alteration of landscapes increasing world-wide, managed forests are increasingly important as providers of ecosystem services including habitat for numerous wildlife species. It is crucial to maintain a balance between timber production and conservation of biodiversity on managed landscapes. Salamander populations can play key roles in the function and diversity of temperate forest ecosystems. Several studies have reported negative effects of forestry on terrestrial plethodontid salamanders, but less research has focused on stream-dwelling species, evaluated mechanisms driving observed shifts in abundance, or described the dynamics of populations residing in managed forests. Using a Before-After-Control-Impact design, we examined the effects …

Experimental Approaches To Understand And Control Salmonella Infection In Poultry, Yichao Yang

Graduate Theses and Dissertations

Salmonella is a major foodborne pathogen around the world and chickens are the major reservoir to transmit Salmonella into the human food chain. For decreasing the infection of Salmonella, we developed six attenuated live vaccines based on Salmonella Enteritidis (SE) and Typhimurium (ST) for testing the cross-serovar and cross-serogroup protection from the challenge of Salmonella Heidelberg and Campylobacter jejuni. One of the constructed vaccine strain showed ability to protect against challenge from Salmonella Heidelberg. Even though some preventive approaches are able to decrease Salmonella colonization in the gastrointestinal tract of chickens or other farm animals, Salmonella transmission mechanisms remain unclear. …

Motives Of Corporate Political Donations: Industry Regulation, Subjective Judgement And The Origins Of Pragmatic And Ideological Corporations, Nicholas M. Harrigan

Research Collection School of Social Sciences

What motivates corporate political action? Are corporations motivated by their own narrow economic self-interest; are they committed to pursuing larger class interests; or are corporations instruments for status groups to pursue their own agendas? Sociologists have been divided over this question for much of the last century. This paper introduces a novel case - that of Australia - and an extensive dataset of over 1,500 corporations and 7,500 directors. The paper attempts to understand the motives of corporate political action by examining patterns of corporate political donations. Using statistical modelling, supported by qualitative evidence, the paper argues that, in the …

Vicarious Liability, Non-Delegable Duty And The Ng Huat Seng Decision, Kee Yang Low

Research Collection Yong Pung How School Of Law

In recent times, courts in Singapore and elsewhere have been grappling with the issue of delegability of duty of care. In the process, they have vigorously defended the conventional position that a duty of care is, in general, delegable. Accordingly, attempts at broadening the ambit of vicarious liability and non-delegable duty, respectively, have been carefully scrutinized. The recent Singapore Court of Appeal decision of Ng Huat Seng v Munib Mohammad Madni adds to the judicial thinking on this complicated and controversial subject.

Federalism And Constitutional Criminal Law, Brenner M. Fissell

Faculty Publications

A vast body of constitutional law regulates the way that police investigate crimes and the way that criminal cases are handled at trial. The Supreme Court has imposed far fewer rules regarding what can be a crime in the first place, how it must be defined, and how much it can be punished. What explains this one-sided favoring of “procedure” over “substance?” This Article aims to unearth and assess the justification that the Court itself most often uses when it refuses to place constitutional limits on substantive criminal law: federalism. While the Court often invokes the concept to rationalize its …

Lactational Performance And Energy Partitioning Of Dairy Cows Supplemented With N-Acetyl-L-Methionine During Mid To Late Lactation, Tyson George Grisenti

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The N-acetyl-L-methionine (NALM) molecule is a methionine (Met) derivative produced via acetylation of the L-Met α-amino group with an N-acetyl group. This molecule has been shown to be bioavailable and capable of fulfilling the dietary requirement for Met in animals and humans. The current experiment was conducted to test a hypothesis that lactating dairy cows fed with NALM would increase milk production by increasing N and energy utilization efficiencies in a dose dependent manner. Eight multiparous Holstein cows that were mid lactation (124 ± 13 days-in-milk) with similar milk production were used in a 4 x …

Measurement Of Agriculture-Related Air Pollutant Emissions Using Point And Remote Sensors, Kori D. Moore

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Measuring air pollution emissions from agricultural activities is usually difficult because of their large area and variability. Traditional air quality sensors, called point samplers, measure conditions in one location, which may not adequately measure a plume. Remote sensors, instruments that measure pollution along a line rather than at a single point, are better able to measure conditions around large areas. This dissertation reports on four agricultural air emissions studies that used both point and remote sensors for comparison. The methods used to calculate the emissions are based on previous work and are further developed in these studies. In particular, an …
