Development of a checklist for use with "clinical observations of gross motor items" tool to refine observations of dysfunctionJordaan, Louisa Maria January 2017 (has links)
A research report submitted to the Faculty of Health Sciences, University of the Witwatersrand, Johannesburg, in partial fulfilment of the requirements for the degree of Master of Science in Occupational Therapy.
Johannesburg, 2017. / Introduction
Appropriate motor coordination is a prerequisite for most occupational tasks (Summers, et al., 2008) (Case-Smith & O'Brian, 2010). Young children develop motor coordination over a period of years (Case-Smith & O'Brian, 2010) (Gallahue, et al., 2012). This can be observed in the development of gross motor skills such as jumping, hopping, skipping etc. (Case-Smith & O'Brian, 2010). Delays in the development of motor coordination can thus have an effect on a child’s development in all other aspects of their life (Gallahue, et al., 2012).
Problem
There is a need in South Africa for a cost-effective standardised tool to evaluate motor coordination in children in a valid and reliable way. Currently standardised tools must be imported from the United States of America (USA) or the United Kingdom (UK) and may not be suitable for South African children. An evaluation tool for motor coordination does exist in South Africa, but its current scoring depends in part on the experience and skill set of the professional to judge the quality of movement during a movement task and its psychometric properties have not been explored.
Aim
This study aimed to identify salient behavioural characteristics that separate children with typical motor coordination development and mild to severe motor coordination dysfunction from each other on the items of the Clinical Observations of Gross Motor Items (COGMI) (SAISI, 2004), in order to provide recommendations to improve the reliability and standardization of the scoring of this tool in the 5 year 0 months – 5 years 11 months age group.
Method
A quantitative, comparative, descriptive, cross-sectional study design was used, with a total of 23 children in this age group. The participants were divided into a typical motor coordination (green) group and a mild to severe motor coordination dysfunction (red) group. They were videoed while performing 15 of the 18 items of the COGMI. These video recordings were analysed using movement analysis to determine specific behaviours which identify function and dysfunction in this age group.
Results
From the observations which could be seen when using the COGMI, clusters could be identified. As the COGMI focuses on coordination of movement rather than postures, the starting and finishing position were discarded and further analysis was only done on the movement component of items. The observations made during the movement portion of items on the COGMI were divided into observations made of the upper limbs, the lower limbs, head, neck and core. Comparisons were made between the two groups and looked at the salient behavioural characteristics that determine function and dysfunction in the age group of five year old children.
Conclusion
Throughout this study it was very clear that this specific age group presents with a lot of variability due to the fact that they are still developing in their gross motor skills and are not yet proficient in fundamental skills. Using these characteristics a checklist of behaviours was developed, which can be used in combination with the COGMI scoring sheet. / MT2017

An Investigation into the Coordination Chemistry of Boratriazine-Based Terpy-Type LigandsSavard, Jamie 04 March 2019 (has links)
The rational design of ligand architectures that enables the development of well-defined metallic constructs has long been recognized as an avenue toward controlling and/or tuning the properties of the corresponding material. To date, one of the most widely studied ligand systems is 2,2’;6’,2”-terpyridine, whose tridentate chelating environment allows for coordination to a variety of metal ions with a wide range of geometries. The development of a terpy-like framework which incorporates a boratriazine moiety into the central ring has been recently reported by the Brusso group, namely 2,2-difluoro-4,6-bis(2-pyridyl)-1,3-dihydro-1,3,5,2-triazaborinine (Py2F2BTA) and 2,2-difluoro-4,6-bis(2-4,6-pyrimidinyl)-1,3-dihydro-1,3,5,2-triazaborinine (Pm2F2BTA). These compounds constitute unfused analogues to the extensively studied boron dipyrromethene (bodipy) family of luminophores, which are known for their high thermal resistance, chemical robustness, low photodegradation, and interesting photophysical signatures. While numerous bodipy derivatives have been studied, metal coordination with these compounds remains an intricate property to explore. Thus, the work presented herein represents the first investigations into the coordination chemistry of these novel ligand frameworks.
Chapter one serves as an introduction to coordination chemistry, exploring important concepts as they relate to the field; the origin of our boratriazine based ligands is also explored within this chapter. Chapter two aims to describe trends in coordination and reactivity of these ligands with iron and cobalt metal sources of different oxidation states. The third and fourth chapter focuses on the targeted use of azide and thiocyanate ligands, respectively, to promote interesting magnetic interactions in related complexes. In the fifth chapter, luminescent metal complexes synthesized through the use of d10 metals are described. Conclusions and future outlooks are then presented in the final section, chapter six.

Indirect Adjustment-Costs Under Alternative Coordination RegimesWernerfelt, Birger 25 September 2003 (has links)
The paper is a study of barriers to communication in terms of agents' incentives to search for and communicate complementary information. In particular, I look at the value of commitment by comparing game forms in which a contract is negotiated prior to, versus after, search and communication. I will use the names "firms" and "markets", respectively, for these two game forms. The comparison depends on three effects. (1) The bargaining power effect: Since the decision to communicate reveals information about preferences, it implies a loss of bargaining power when the players negotiate ex post. This hurts the incentives to communicate and therefore the incentives to search. (2) The incentive transfer effect: If the gains from adjustment accrue unevenly, ex ante negotiation may leave one of the players without incentives to communicate and search. With ex post negotiation, that player can bargain for a share of the gains. (3) The bargaining efficiency effect: The negotiation process itself may be more efficient ex post because more information has been revealed. The net effect depends on the magnitude of the gains and their accrual. If negotiation normally leads to agreement, it is better done ex ante in cases where adjustments yield smaller, more evenly accruing gains. When gains are larger and accrue less evenly, ex post negotiation implements more communication and search

Movement coordination and control in children with and without Developmental Coordination Disorder in ball catchingPrzysucha, Eryk 06 1900 (has links)
A rigorous investigation of functional collectives of musculo-skeletal articulators is lacking in DCD literature, in spite of powerful empirical arguments suggesting that they represent a critical unit of control (e.g., coordinative structure theory). Thus, the purpose of this dissertation was to examine how children with and without DCD coordinate and control their actions in a multi-degrees of freedom task, such as ball catching. The first study focused on the development of a protocol and qualitative measures capable of examining ball catching performance in children of varying skill levels. The second study involved a replication of the previously devised protocol with a larger group of individuals with and without DCD. The third phase involved a more in-depth analysis of spatial and temporal aspects of movement coordination and control using kinematics.
Typically developing boys effectively coordinated and controlled their actions regardless of the task constraints. This confirms that by 10-11 years of age ball catching, and the underlying perceptual-motor mechanisms, are well developed. The analysis of the emerging tendencies showed that they coupled and decoupled the existing spatio-temporal coordinative relations depending on the task constraints, and biomechanical properties of the relevant elements involved. This supports the notion that optimal movement coordination reflects the ability to re-organize the relevant coordinative structures, given the existing constraints.

A computational approach to study the effect of multiple lymphangion coordination on lymph flowMadabushi Venugopal, Arun 01 November 2005 (has links)
The lymphatic system acts to return fluid from the interstitial space back into the blood circulation. In normal conditions, lymphangions, the segment of lymphatic vessel in between valves, cyclically contract and can pump lymph from low pressure tissues to the higher-pressure veins of the neck. With edema, however, this pressure gradient can reverse, and the role of contraction is less clear. Like ventricles, lymphangions are sensitive to both preload and afterload. Unlike ventricles, lymphangions are arranged in series, so that the outlet pressure of one lymphangion becomes the inlet pressure of another. Anything that alters the relative timing and frequency of adjacent lymphangions alters both preload and afterload of each lymphangion and thus mean lymph flow. To explore the effect of timing and frequency of contraction on lymph flow, we developed a computational model of a lymphatic vessel with lymphangions described by the classic description of time-varying elastance. When pumping up a pressure gradient, as in normal conditions, or when pumping down a pressure gradient, as in some cases of edema, we found that flow was optimized when the lymphangions in the vessel were pumping with a very short time delay between their cycles, and the flow was reduced when the time delay between the contractions was reduced to zero. However, a difference in frequency between adjacent lymphangions alters instantaneous flow but does not affect mean flow. These results suggest an important role for the timing of the contraction in optimizing lymph flow. However, a difference in frequencies between adjacent lymphangions has little effect on altering lymph flow, suggesting that tight control of lymphangion coordination may not be critical for lymphatic function.

Hudiksvalls samordningsmodell- en modell för att underlätta samverkan?Gradin, Åsa, Andersson, Camilla January 2011 (has links)
Abstract Hudiksvalls coordinating model - a model to make cooperation easier Camilla Andersson and Åsa Gradin The purpose of this study was to examine the experience each one of the administrators have of their own new model in Hudiksvall to make cooperation easier for the three different administrations in Hudiksvalls municipality. The study will focus on the administrators experiences of Hudiksvalls coordinating design. Questions of the study were: How is the influence of the model on the rules? How is the influence of the model on expectations and parts? What kind of influence did the model have on the responsibility distribution? What kind of influence has the model on the responsibilities at the transfer of costs? To answer the questions of the study we applied a qualitative method, it was made through a standardization interview guide and open questions, with six of the dealing officers who works with the model. Some of the results wich can be discern are by an economic character, andfor the clients that they won`t be passed around the administrations in the community, they get the right help, quick and safe. Key words: cooperation, coordination. / Abstrakt Hudiksvalls samordningsmodell- en modell för att underlätta samverkan. Camilla Andersson och Åsa Gradin Studiens syfte var att undersöka hur berörda handläggare upplever den nya egna Hudikmodellen för att underlätta samverkan bland tre olika förvaltningar i Hudiksvalls kommun. Det vill säga denna studie intresserar sig för handläggarnas upplevelse av Hudiksvalls samordningsmodell. Studiens frågeställning var: Hur har modellen påverkat reglerna? Hur har modellen påverkat förväntningar och roller? Vilken påverkan har modellen haft på ansvarsfördelningen? Vilken påverkan har modellen för kostnadsansvaret? För att besvara frågeställningen tillämpades en kvalitativ metod och utgjordes av en standardiserad intervjuguide med öppna frågor med sex handläggare som arbetar med modellen. Några resultat som kan skönjas är dels av ekonomisk karaktär, samt att klienterna inte längre slussas mellan förvaltningarna utan får rätt hjälp snabbt och tryggt. Nyckelord: samverkan, samordning.
