Profiles for the radial focusing energy-critical wave equation in odd dimensions
Casey Rodriguez
Mathematics , 2014,
Abstract: In this paper we consider global and non-global radial solutions of the focusing energy--critical wave equation on $\mathbb{R} \times \mathbb{R}^N$ where $N \geq 5$ is odd. We prove that if the solution remains bounded in the energy space as you approach the maximal forward time of existence, then along a sequence of times converging to the maximal forward time of existence, the solution decouples into a sum of dynamically rescaled solitons, a free radiation term, and an error tending to zero in the energy space. If, in addition, we assume a bound on the evolution that rules out formation of multiple solitons, then this decoupling holds for all times approaching the maximal forward time of existence.
A partial data result for less regular conductivities in admissible geometries
Casey Rodriguez
Mathematics , 2014,
Abstract: We consider the Calder\'on problem with partial data in certain admissible geometries, that is, on compact Riemannian manifolds with boundary which are conformally embedded in a product of the Euclidean line and a simple manifold. We show that measuring the Dirichlet-to-Neumann map on roughly half of the boundary determines a conductivity that has essentially 3/2 derivatives. As a corollary, we strengthen a partial data result due to Kenig, Sj\"ostrand, and Uhlmann.
Expectations, Means-Tested Subsidies, and Economic Performance during the Recession  [PDF]
Casey B. Mulligan
Journal of Mathematical Finance (JMF) , 2017, DOI: 10.4236/jmf.2017.73029
Abstract: The aggregate neoclassical growth model with only one impulse—means-tested subsidies whose replacement rates began rising at the end of 2007—produces time series for aggregate labor usage, consumption, investment, and real GDP that closely resemble actual US time series. Despite having no explicit financial market, the model has investment fall steeply during the recession not because of any distortions with the supply of capital, but merely because labor is falling and labor is complementary with capital in the production function. Through the lens of the model, the fact that real consumption fell significantly below trend during 2008 suggests that market participants were expecting labor usage to remain depressed for several years to come.
Developing Trust In Virtual Software Development Teams
Casey,Valentine;
Journal of theoretical and applied electronic commerce research , 2010, DOI: 10.4067/S0718-18762010000200004
Abstract: today globally distributed software development has become the norm for many organizations and the popularity of implementing such an approach continues to increase. in these circumstances a strategy often employed is the use of virtual software development teams. due to the collaborative nature of software development this has proved a difficult and complex endeavor. research has identified distance in its various forms as an important factor which negatively impacts on global software development and on virtual software team operation in particular. in this context, the aspects of distance have been defined as temporal, geographical, cultural and linguistic. a key element for the success of any team based project is the development of trust and cooperation. each aspect of distance can negatively impact on the development of trust and hamper cooperation particularly in the virtual team environment. an additional factor which this research identified is the importance and negative impact fear plays. the serious implications of these factors are due to the need for dependence on asynchronous and online communication which is inherent to global software development and the operation of virtual software teams in particular. the findings presented here are the results from four independent studies undertaken over a twelve year period which consider each of these issues. having identified the problems associated with trust and communication, how these issues were successfully addressed and managed on a multimillion dollar project which was heading for failure is outlined.
Feser on Rothbard as a Philosopher
Gerard Casey
Libertarian Papers , 2009,
Abstract: In “Rothbard as a philosopher” (Feser 2006) Edward Feser harshly criticises the philosophical abilities of Murray Rothbard. According to Feser, Rothbard seems unable to produce arguments that don’t commit obvious fallacies or produces arguments that fail to address certain obvious objections. His criticism centres on what he regards as Rothbard’s principal argument for the thesis of self-ownership. In this paper, I attempt to show that Feser’s criticism fails of its purpose and that Rothbard is very far from being the epitome of philosophical ineptitude that Feser takes him to be.
Roger Williams’s Unintentional Contribution to the Creation of American Capitalism
Casey Pratt
Libertarian Papers , 2011,
Abstract: This paper argues that in attempting to protect the religious life from the sullying influence of worldly affairs, Roger Williams participated, albeit unintentionally, in creating the economic conditions that led to the birth of American capitalism. Although Williams argued for a separation of church and state, he did so not in the interest of defending economic liberty, but instead to preserve the sanctity of the church against the frequent immorality that seemed to him required in worldly governance. Questions of pricing and wages, lending and interest—issues that would until Williams’s intervention have been handled by the church in terms of Aquinas’ just price theory—fell outside of the church’s purview according to the new model described by Williams. The result was the creation of an “amoral” public space where the effective separation between spiritual and material concerns led to a kind of free-by-default economic marketplace. This paper traces the development and inadvertent consequences of this essentially theological idea as it took shape in the colonial era.
To prevent or pursue displacement?
Casey Barrs
Forced Migration Review , 2012,
Abstract: The repertoire of survival actions of at-risk civilians includes bothavoiding and attempting displacement. But there are also overlaps,combinations and tacking back and forth between the two, whiletrying to mitigate the risks that any choice entails.
Designing for Learning: Online Social Networks as a Classroom Environment
Gail Casey
International Review of Research in Open and Distance Learning , 2011,
Abstract: This paper deploys notions of emergence, connections, and designs for learning to conceptualize high school students’ interactions when using online social media as a learning environment. It makes links to chaos and complexity theories and to fractal patterns as it reports on a part of the first author’s action research study, conducted while she was a teacher working in an Australian public high school and completing her PhD. The study investigates the use of a Ning online social network as a learning environment shared by seven classes, and it examines students’ reactions and online activity while using a range of social media and Web 2.0 tools.The authors use Graham Nuthall’s (2007) “lens on learning” to explore the social processes and culture of this shared online classroom. The paper uses his extensive body of research and analyses of classroom learning processes to conceptualize and analyze data throughout the action research cycle. It discusses the pedagogical implications that arise from the use of social media and, in so doing, challenges traditional models of teaching and learning.
Haitians’ Labor and Leisure on Cuban Sugar Plantations: The Limits of Company Control
Matthew Casey
New West Indian Guide , 2011,
Abstract: This article challenges the common notion that Cuban sugar companies controlled the labor and social relations of Haitian immigrant laborers fully and without challenge during the first half of the 20th century. It begins by showing the way that Cuban newspapers and sugar company administrators projected an image of Haitians as a homogenous group of powerless, culturally isolated cane cutters who were separated from other groups through an idealized labor hierarchy. Then it details Haitians’ laboring lives on Cuban sugar plantations to demonstrate three things. First, that Haitians participated in other aspects of sugar production, including skilled positions within centrales. Second, that cane cutters themselves were divided by their skill levels and (in)formal hierarchies. Third, that Haitians worked alongside individuals of other nationalities in both sugar fields and the mills where cane was processed. The essay ends by analyzing Haitians’ attempts to carve out autonomy in their work and leisure hours by exerting control over their labor and creating various types of commercial and social networks with individuals of other nationalities on plantations.
