A Mechanized Theory Of Communication Analysis In Cml, Thomas Logan

Theses

For this master's thesis, I have developed a formal semantics of a language with concurrent processes (or threads), an initial formal analysis, along with related theorems and formal proofs. The language under analysis is a very simplified version of Concurrent ML. The formal analysis recasts an analysis with informal proofs developed by Reppy and Xiao. It categorizes communication described by programs into simple topologies. One description of topologies is static; that is, it describes all static topologies of a program in a finite number of steps. Another description is dynamic; that is, it describes topologies in terms of running a …

Effects Of Eat Better, Move More (Ebmm) Educational Program On Obesity Rates In Latino Children Residing In Northwest Arkansas, Allison Jones

The Eleanor Mann School of Nursing Undergraduate Honors Theses

Background: Childhood obesity, especially in ethnic minority populations, is a growing problem with no signs of improvement over the past decade. The Latino population is one of the fastest growing minority groups in the United States. Unfortunately, they have experienced substantial health disparities and socioeconomic disadvantages that contribute to the high rates of obesity in their youth. Decreasing obesity rates would not only have many health advantages, but also financial benefits as well. It would reduce the risk of co-morbidities such as cardiovascular disease and depression. Healthy children are more likely to grow into healthy adults, ultimately lowering the cost …

The Federal Government Has An Implied Moral Constitutional Duty To Protect Individuals From Harm Due To Climate Change: Throwing Spaghetti Against The Wall To See What Sticks, Hope M. Babcock

Georgetown Law Faculty Publications and Other Works

The continuing failure of the federal government to respond to the growing threat of climate change, despite affirmative duties to do so, creates a governance vacuum that the Constitution might help fill, if such a responsibility could be found within the document. This Article explores textual and non-textual constitutional support for that responsibility, finding that no single provision of the Constitution is a perfect fit for that responsibility. However, the document as a whole might support constitutionalizing an environmental protection norm as an individual right or affirmative government obligation given the norm's importance to the enjoyment of other constitutional rights …

Government Funding Of Town Councils: The Role Of Private Law, Benjamin Joshua Ong

Research Collection Yong Pung How School Of Law

Section 42 of theTown Councils Act (Cap 329A, 2000 Rev Ed) provides for the Government toprovide grants to Town Councils “subject to such conditions as theMinister may determine”. The imposition of such conditions can beuseful in theory. However, there is no clear mechanism by which suchconditions may be enforced. This article proposes that this lacuna befilled as follows: such conditions are to take the form of private-lawrelationships between the Government and Town Councils. After outliningthe benefits of this proposal, the article critiques the Court of Appeal’sdecision in a 2016 case which held that such private-lawrelationships cannot exist as a matter …
