Is Groenvlei really fed by groundwater discharged from the Table Mountain Group (TMG) Aquifer?
R Parsons
Water SA , 2009,
Abstract: Vankervelsvlei is a unique wetland located in the stabilised dunes east of Sedgefield. Groenvlei is one of a series of 5 brackish coastal lakes along the Southern Cape coast of South Africa, but is the only one disconnected from the sea. It has been hypothesised that discharge from the underlying Table Mountain Group Aquifer sustains Vankervelsvlei, which in turn discharges into Groenvlei. This paper critically reviews the conceptual model and information on which the hypothesis was based. It is argued that the conceptual model is flawed as it does not take account of topographical and geohydrological conditions prevalent in the area. Analysis of limited hydrochemical data did not explore other possible water sources, and the electrical conductivity characteristics used to confirm the link between the wetlands and the deeper secondary aquifer also apply to 56.3% of boreholes located in a variety of aquifer types across the Western Cape Province. No information is available that supports a link to the Table Mountain Group. Rather, it appears that Vankervelsvlei is sustained by direct rainfall and there is no hydraulic link between Vankervelsvlei and Groenvlei.

The Space of Remembering: Collective Memory and the Reconfiguration of Contested Space in Argentina’s ESMA
Parsons, Emily
452o F : Revista de Teoría de la Literatura y Literatura Comparada , 2011,
Abstract: This paper explores the ongoing history of the ESMA museum’s developmentand argues that the intrinsic and conflictual collective memory work involved is characterized by competing desires to remember and to forget, rooted in the physical,visible, and public space of ESMA.
Interpreta o da arte através de metáforas =Interpreting art through metaphors
Parsons, Michael
Educa??o , 2011,
Abstract: O artigo aborda o pensamento nas artes através da metáfora. Reconhece a relevancia da posi o de Lakoff e Johnson, que veem a metáfora como a maneira fundamental pela qual elaboramos os significados das nossas experiências corporais. Contudo, a maior parte das pesquisas refere-se às metáforas verbais. O presente trabalho enfoca as metáforas visuais, especificamente, se e como as metáforas na mídia visual s o diferentes de metáforas na mídia verbal, tendo como referência a obra de Max Black, que defende o ponto de vista de que a metáfora é basicamente uma quest o de pensamento e n o simplesmente uma figura de linguagem. The article discusses thinking in the arts through metaphors. It acknowledges the relevance of Lakoff and Johnson’s position. They see metaphors as the essential way in which we work through the meanings of our bodily experiences. However, most of the research refers to verbal metaphors. This study focuses on visual metaphors, specifically, whether and how metaphors in visual media are different from metaphors in verbal media, based on a reference to the work of Max Black who advocates the point of view that a metaphor is basically a matter of thinking and not simply a figure of language.
A Study of Critical Experiences within Small Business Development
Anderson Parsons
International Journal of Business and Management , 2009,
Abstract: This paper builds a deeper understanding of critical experiences during the growth of a small business. Based on qualitative, case study research, it suggests that greater clarity is needed in defining what makes an event ‘critical’. The concept of ‘critical episodes’ is introduced, as the term ‘critical incident’ can sometimes trivialise how fundamental and prolonged certain critical experiences can be for both the owner-manager and the business. The paper goes on to examine the relationship between critical incidents and wider critical episodes, introducing several key developmental roles that critical incidents can play within broader periods of organisational transition and change. The research demonstrates that critical experiences can act as ‘triggers’ for both organisational growth and entrepreneurial development. The significant emotional dimension of critical experiences is then discussed, demonstrating that the concept of crises, as described by life cycle theorists, does not adequately capture this important aspect of criticality. The paper concludes by developing conceptual links between crises and critical experiences during the growth process.
Reform of the House of Lords: a “parliamentary version of Waiting for Godot”?
Michael PARSONS
E-rea : Revue électronique d’études sur le Monde Anglophone , 2009, DOI: 10.4000/erea.943
Abstract: Après la mise en uvre rapide de la première phase de réforme de la Chambre des Lords, les projets devant conduire à la deuxième phase ont peu avancé. S’il y a un certain consensus pour dire que la réforme est nécessaire, il y a des divergences importantes entre les deux chambres sur la fa on de la réaliser, notamment à propos du mode de désignation des membres de la chambre réformée (nomination ou élection). La conjoncture économique et politique fait qu’une telle réforme constitutionnelle n’est guère prioritaire. Pourtant le mode de fonctionnement de la chambre a évolué au cours de la dernière décennie. Elle s’affirme davantage et s’est donnée un r le important dans la préservation des libertés individuelles et dans l’examen des implications constitutionnelles de toute nouvelle législation. Ceci soulève un paradoxe, la chambre non-élue se montrant peut-être davantage attachée à la préservation des droits démocratiques que les députés élus de la Chambre des Communes. Une Chambre des Lords élue jouirait d’une plus grande légitimité pour remplir cette fonction particulière et, plus généralement, pour obliger le gouvernement à rendre des comptes sur son action. After the rapid implementation of phase one of House of Lords reform, plans for further change, or phase two of the reform, have made little progress. While there is agreement that reform is necessary, there are fundamental differences between the upper and the lower chamber as to how this should be achieved, especially concerning the mode of designation of members of the reformed House (appointment or election). The unsettled economic and political environment means that constitutional reform is not top on the agenda. However there have been important changes in the way the semi-reformed House of Lords has operated over the last few years. It has become much more assertive and has assumed a valuable role in preserving individual freedoms and scrutinising the constitutional implications of any proposed legislation. This poses something of a paradox in that it might be argued that the unelected upper chamber has been more concerned to preserve democratic rights than the elected House of Commons. An elected House of Lords would enjoy greater legitimacy in fulfilling this role in particular and in more generally holding the government to account.
Collaborative oral health education for caregivers in an assisted-living facility
Susan Parsons
Journal of Nursing Education and Practice , 2012, DOI: 10.5430/jnep.v3n3p44
Abstract: Background: The purpose of this study was to implement a collaborative oral health project and evaluate its effectiveness for caregivers in an assisted-living facility. An interdisciplinary study was conducted by nursing and dental hygiene faculty. Methods: A quasi-experimental design was utilized with a pre-post treatment format. Pre-and post-treatment scores were analyzed from a convenience sample of 13 caregivers in an assisted-living facility. The information addressed oral care assessments, interventions, evaluation and referral guidelines. Results: Post-treatment scores were significantly higher than pre-treatment scores (p=.002). The results indicate the collaborative teaching project was effective increasing knowledge of assisted-living caregivers regarding oral hygiene practices for older adults. Conclusions: Based on these findings the results indicate collaborative oral health care teaching project was effective in increasing caregiver oral hygiene knowledge. It was concluded that the collaborative instruction was effective. Other considerations included positive outcomes on a follow-up survey assessment of caregivers and assisted-living management regarding utilization of new information that had been presented.
T-Duality and Conformal Invariance at Two Loops
S. Parsons
Physics , 1999, DOI: 10.1103/PhysRevD.61.086002
Abstract: We show that the conformal invariance conditions for a general sigma-model with torsion are invariant under T-duality through two loops.
Loop-Erased Random Surfaces
Kyle Parsons
Mathematics , 2015,
Abstract: We present a model of loop erased random surface that generalizes the connection between loop erased random walks and uniform spanning trees. We performed numerical experiments on the loop erased random surface on an $n\times n\times n$ grid as $n$ grows. We hypothesize that the growth exponent of the loop erased random surface as $n\to\infty$ is $18/ 7$. We also performed numerical experiments on the loop erased random surface on an $n\times n\times n$ torus graph and conclude that the growth exponent is most likely not $18/ 7$.
Refining Reasoning in Qualitative Probabilistic Networks
Simon Parsons
Computer Science , 2013,
Abstract: In recent years there has been a spate of papers describing systems for probabilisitic reasoning which do not use numerical probabilities. In some cases the simple set of values used by these systems make it impossible to predict how a probability will change or which hypothesis is most likely given certain evidence. This paper concentrates on such situations, and suggests a number of ways in which they may be resolved by refining the representation.
