\section*{Abstract}We study Maker-Breaker games played on the edges of the complete graph on $n$ vertices, $K_n$, whose family of winning sets $\cF$ consists of all edge sets of subgraphs $G\subseteq K_n$ which possess a predetermined monotone increasing property. Two players, Maker and Breaker, take turns in claiming $a$, respectively $b$, unclaimed edges per move. We are interested in finding the threshold bias $b_{\cF}(a)$ for all values of $a$, so that for every $b$, $b\leq b_{\cF}(a)$, Maker wins the game and for all values of $b$, such that $b>b_{\cF}(a)$, Breaker wins the game. We are particularly interested in cases where both $a$ and $b$ can be greater than $1$. We focus on the \textit{Connectivity game}, where the winning sets are the edge sets of all spanning trees of $K_n$ and on the \textit{Hamiltonicity game}, where the winning sets are the edge sets of all Hamilton cycles on $K_n$.Next, we consider biased $(1:b)$ Avoider-Enforcer games, also played on the edges of $K_n$. For every constant $k\geq 3$ we analyse the $k$-star game, where Avoider triesto avoid claiming $k$ edges incident to the same vertex. We analyse both versions of Avoider-Enforcer games, the strict and the monotone, and for each provide explicit winning strategies for both players. Consequentially, we establish bounds on the threshold biases $f^{mon}_\cF$, $f^-_\cF$ and $f^+_\cF$, where $\cF$ is the hypergraph of the game (the family of target sets).We also study the monotone version of $K_{2,2}$-game, where Avoider wants to avoid claiming all the edges of some graph isomorphic to $K_{2,2}$ in $K_n$. Finally, we search for the fast winning strategies for Maker in Perfect matching game and Hamiltonicity game, again played on the edge set of $K_n$. Here, we look at the biased $(1:b)$ games, where Maker's bias is 1, and Breaker's bias is $b, b\ge 1$.

ITC/USA 2012 Conference Proceedings / The Forty-Eighth Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2012 / Town and Country Resort & Convention Center, San Diego, California
The Western Aeronautical Test Range of the National Aeronautics and Space Administration's Dryden Flight Research Center needed to address the aging software and hardware of its current situational awareness display application, the Global Real-Time Interactive Map (GRIM). GRIM was initially developed in the late 1980s and executes on older PC architectures using a Linux operating system that is no longer supported. Additionally, the software is difficult to maintain due to its complexity and loss of developer knowledge. It was decided that a replacement application must be developed or acquired in the near future. The replacement must provide the functionality of the original system, the ability to monitor test flight vehicles in real-time, and add improvements such as high resolution imagery and true 3-dimensional capability. This paper will discuss the process of determining the best approach to replace GRIM, and the functionality and capabilities of the first release of the Positional Awareness Map 3D.

Abstract:

Positional proteomics is emerging as an attractive technique to characterize protein termini, which play important biological roles in cells. Even with the advances in past decades, there still are areas for improvement. This thesis focuses on improving data quality and assignment confidence in positional proteomics. A novel workflow was designed for the large-scale identification of protein N-terminal sequences. 4-sulfophenyl isothiocyanate (SPITC) is used for N-termini sulfonation; Upon higher energy collisional dissociation (HCD), SPITC peptides in electrospray ionization ESI generate predominately y-type ion series; such simplification of spectra enables the identification of N-termini with high fidelity. The presence of b1 + SPITC product ions upon HCD furthers the confidence for N-terminal identifications. Secondly, sulfonated N-terminal peptides possess one negative charge site at low pH, which was exploited to enrich the SPITC modified N-terminal peptides by electrostatic repulsion hydrophilic interaction (ERLIC) chromatography. Such enrichment process allows both N-termini enriched and N-termini deficient fractions to be collected and analyzed by LC-MS/MS. This method was applied to an E. coli cell lysate, identifying approximately 350 N-terminal peptides (85% represented neo-N-termini from protein degradation and 15% from leading methionine excision). These N-terminal peptides represented 274 distinct E.coli proteins, 224 of which were also identified in the analysis of flow-through fractions from internal peptides. Another approach we took to boost the identification confidence is by exploiting iTRAQ (isobaric tag for relative and absolute quantitation) in the positional proteomics workflow. This approach allows for multiplexed comparison between different samples, and thus is well-suited for degradadomics analyses where degraded samples are compared to control samples. Both control and protease treated sample are labeled by different tags which allows direct comparison of protein N-termini with neo-N-termini. In addition, samples are analyzed duplicate by labeling with two tags, aiming for quick validation of peptides by internal replicates. In this study, Asp-N digested E.coli cell lysate is taken as a model system. A total of 500 N-terminal peptides, corresponding to 370 proteins, were identified with high confidence in one experiment, with 87% of those proteolytic products matching the expected protease digestion specificity, validating the assignment accuracy of this approach.

Abstract:

Data from a Coarse Acquisition (C/A) Global Positing System (GPS) map-grade receiver were evaluated to assess the accuracy of differentially corrected points. Many studies have focused on the accuracy of GPS units under ideal data collection conditions. Ideal conditions allow the collection of data with four satellites (3D mode), yet field data conditions are often less than ideal. Four satellites may not always be in view because of mountainous topography, heavy forest cover, or other obstructions which block satellite signals from the receiver. This study examines GPS accuracy when four satellites are not available, instead collecting data with only three satellites (2D mode).

3D GPS points compute four unknowns: x, y , z, and clock error. In comparison, 2D GPS points are less accurate as only three unknowns are calculated: x, y, and clock error. Elevation (or z) is not computed for 2D points, causing increased error in the horizontal (x, y) measurement. The effect of elevation was evaluated on 234 2D GPS data points. These points were collected and corrected at elevation intervals of true elevation, +-25 meters, +- 50 meters, and +-75 meters. These 2D points were then compared to surveyed points to measure the effect vertical error has on horizontal accuracy. In general, the more error in the vertical estimate during correction, the greater the horizontal error.

Abstract:

Mestrado em Economia
Positional consumption led by wants linked to status concerns arguably does not produce welfare gains to society and is a source of economic inefficiency. While some authors propose policy remedies to bring a better collective outcome, others argue that they would cause more damage than benefits. One of the most important arguments against intervention is that positional consumption generates innovation, thereby producing wider economic benefits. This work aims to contribute to the discussion by studying the relation between positional consumption and technological innovation. It departs from commonly accepted theoretical assumptions on elements structuring the relation, and infers on its causes and possible outcomes. Besides achieving a better comprehension of the process, results indicate that positional consumption is likely to generate lower benefits from technological innovation than alternative resource allocations of material nature. This conclusion is founded on three arguments, related to the relative role of technological innovation as a marketing strategy in positional markets, the exigency of positional consumers towards the material achievements of innovations, and the ability of those innovations to deliver welfare gains.
O consumo positional orientado por anseios de estatuto nao produz, de forma plausível, ganhos de bem-estar para a sociedade, e e nesse caso uma fonte de ineficiencia económica. Enquanto que alguns autores propõem políticas para corresponder a este problema, outros argumentam que estas causariam mais danos do que benefícios. Um dos argumentos mais relevantes contra a intervencao política e o de que o consumo posicional gera inovacao, dessa forma produzindo benefícios economicos mais vastos. O presente trabalho pretende contribuir para esta discussão atraves do estudo da relacao entre o consumo posicional e a inovação tecnologica. Para tal, parte-se de pressupostos teoricos comummente aceites sobre elementos que estruturam a relacao em questao, e infere-se sobre as suas causas e consequencias. Para alem de permitir uma melhor compreensãao do processo, os resultados do estudo indicam que o consumo posicional gera, provavelmente, menos benefícios sobre a inovaçcãao tecnoloígica do que alternativas de afectaçcaão de recursos de natureza material. Esta conclusaão funda-se em três argumentos, relacionados com o papel relativo da inovacão tecnolígica como estratégia de marketing em mercados posicionais, com a exigencia dos consumidores posicionais sobre o desempenho material das inovaçcãoes, e com a capacidade das in-ovacçãoes geradas pelo consumo posicional para oferecerem benefícios de bem-estar.

Abstract:

Purpose: The purpose of this study was to evaluate the effectiveness of triaging patients with motion-provoked dizziness into a benign paroxysmal positional vertigo (BPPV) clinic. Method: A retrospective chart review was performed of veterans who were tested and treated for BPPV in a triaged BPPV clinic and veterans who were tested and treated for BPPV in a traditional vestibular clinic. Results: The BPPV triage clinic had a hit rate of 39%. On average, the triaged BPPV clinic reduced patient wait times by 23 days relative to the wait times for the traditional vestibular clinic while also reducing patient costs. Conclusion: Triaging patients with BPPV is one method to improve access to evaluation and treatment and a mechanism for the effective use of clinic time and resources.

Full text

Abstract:

This thesis aims to investigate and develop two positional calibration methods that can be applied to a linear pipetting robot. The goal of the calibration is to detect displacements that have been made to objects that are located in the the robot’s reference system and try to estimate their new position. One of the methods utilizes the pressure system that is mounted on the robot’s arm. The pressure system was able to detect surfaces by blowing air through a pipette against desired surfaces. Positional information of targeted objects are acquired by using the surface detection feature against an extruded square landmark that acts as a reference for estimating displacements. The other method uses a barcode scanning camera by using its images to detect and retrieve positional information on Aruco markers. Estimation of the targeted object is done by tracking the movement of the Arucos position and orientation. Tests were made in order to analyse the performance of both methods and to verify that the requirement of 0.1 mm accuracy and precision could be obtained. The tests were limited to analysing the methods performance on stationary targets to guarantee that the methods did not detect incorrect displacements. It was found that the camera method could fulfill the requirement when it came to estimating XY-coordinates by using multiple images and placing the Aruco marker within a reasonable distance to the targeted object. However, the camera method was not accurate when it came to estimating the Z-coordinates of objects. As for the pressure method, it was able to fulfill the requirement when it came to estimating Z-coordinates, but its ability to estimate the XY-coordinates of an object was not sufficient. A recommendation would be combine both methods so that they can compensate each other by using the camera method for estimating the XY-coordinates and the pressure method for estimating the Z-coordinates.

Abstract:

Inledning: Många studier har fokuserat på ADHD-barn, föräldrars, lärares och syskons olika perspektiv på ADHD och hur det är att leva med diagnosen. Studier har också visat att barn med ADHD ofta överskattar sin prestation i förhållande till hur andra uppfattar den. Detta fenomen kallas ”positive illusory bias” (Hoza, Pelham, Dobbs, Owen & Pillow, 2002). Syftet med denna studie är att undersöka hur barn med ADHD beskriver sig själva och hur de uppfattar att de betraktas av sin familj, lärare och kompisar. Detta perspektiv har inte studerats tidigare. Frågeställningar: Vilka föreställningar har barn med ADHD om sig själva? Vilka föreställningar har barn med ADHD om hur de betraktas av sina familjer, lärare och kompisar? Metod: Åtta barn med diagnosticerad ADHD i åldrarna 9-12 år har i en kvalitativ studie intervjuats med semistrukturerade frågor och svaren har analyserats utifrån tematisk analysmetod. Resultat: Till skillnad från tidigare forskningsresultat uttryckte de flesta barnen ingen tydlig ADHD-identitet i synen på sig själv. Däremot uppfattade flertalet att föräldrar och lärare såg ADHD-symtom hos barnet. Detta i kontrast till kompisarnas syn som oftast inte uttryckte sig i ADHD-symtom. Diskussion: Utifrån begreppet ”positionell objektivitet” (Sen, 1993) diskuteras resultaten där flera tänkbara positionella parametrar presenteras.
Introduction: A number of studies have examined children with ADHD, how it is to live with this diagnosis, and the different perspectives of parents, teachers and siblings. In several studies, it has been shown that children with ADHD often overestimate their capability compared to other persons’ assessment of their capability. This phenomenon is called “positive illusory bias” (PIB) (Hoza, Pelham, Dobbs, Owen &Pillow, 2002). The aim of this study is to examine how ADHD-children describe themselves and how they think that they would be described by their family, teachers, and mates. It seems that this has not previously been studied. Questions: How do children with ADHD describe themselves? How do these children think that they would be described by their family, teachers and mates? Method: Eight children, diagnosed with ADHD and between 9 and 12 years of age, are interviewed with semi-structured questions and the answers have been analysed by thematic methodology. Result: In contrast to previous studies, most children did not express any clear ADHD-identity in their description of themselves. However, ADHD-symptoms were quite common in their accounts of how they thought that their parents and teachers would describe them. This was in contrast to their accounts of how they thought that their mates would describe them, where the children seldom mentioned aspects related to ADHD-symptoms. Discussion: The discussion of the results is based on the concept of “positional objectivity” (Sen, 1993), in which several plausible positional parameters are presented.

Full text

Abstract:

Proteome complexity presents a major challenge in the field of proteomics. The majority of bottom-up methods begin with proteolysis, which increases the number of analytes in the mixture by about 30-50 fold. This level of complexity demands simplification, and there is an increasing requirement for strategies and reagents that reduce the complexity of a total proteome mixture. It may be argued that when analysing a complete protein digest, for instance by standard shotgun methods, more peptides are analysed than strictly necessary. An efficient proteomic strategy simplifies the proteome while preserving most of the information necessary for comprehensive analysis. A practical approach to proteome simplification is to target a specific structural region of the protein molecule. The ultimate simplification strategy would be to select a single signature peptide from each protein in the proteome.

Full text

Abstract:

The speech of a person speaking in a noisy environment can be enhanced through electronic beamforming using spatially distributed microphones. As this approach demands precise information about the microphone locations, its application is limited in places where microphones must be placed quickly or changed on a regular basis. Highly precise calibration or measurement process can be tedious and time consuming. In order to understand tolerable limits on the calibration process, the impact of microphone position error on the intelligibility is examined. Analytical expressions are derived by modeling the microphone position errors as a zero mean uniform distribution. Experiments and simulations were performed to show relationships between precision of the microphone location measurement and loss in intelligibility. A variety of microphone array configurations and distracting sources (other interfering speech and white noise) are considered. For speech near the threshold of intelligibility, the results show that microphone position errors with standard deviations less than 1.5cm can limit losses in intelligibility to within 10% of the maximum (perfect microphone placement) for all the microphone distributions examined. Of different array distributions experimented, the linear array tends to be more vulnerable whereas the non-uniform 3D array showed a robust performance to positional errors.

Full text

Abstract:

Geospatial data almost always contains some amount of uncertainty due to inaccuracies in its acquisition and transformation. While the data is commonly visualized (e.g. on digital maps), there are unanswered needs for visualizing uncertainty along with it. Most research on effectively doing this addresses uncertainty in data values at geospatial positions, e.g. water depth, human population, or land-cover classification. Uncertainty in the data’s geospatial positions themselves (positional uncertainty) has not been previously focused on in this regard. In this thesis, techniques were created for visualizing positional uncertainty using World Vector Shoreline as an example dataset. The techniques consist of a shoreline buffer zone to which visual effects such as gradients, transparency, and randomized dots were applied. They are viewed interactively via Web Map Service (WMS). In clutter testing with human subjects, a transparency-gradient technique performed the best, followed by a solid-fill technique, with a dots-density-gradient technique performing worst.

Abstract:

Positioning in environments where GPS is absent is a field currently under intensive research.Systems are currently being researched or designed for indoor use, often relying on ultra-wideband radio, ultrasound, fingerprinting or Wi-Fi.For underground mining, the problem is magnified, as installation of new equipment is expensive.Mobilaris Mining and Civil Engineering AB supplies a service, Mobilaris Mining Intelligence, using existing Wi-Fi infrastructure present in many mines for communication, and has developed two Wi-Fi-based positioning methods and one hybrid system, using dead reckoning and gyroscope.The first positioning method, Positioning Method 1, positions resources at the location of the strongest access point.The other positioning method, Positioning Method 4, uses signal strength values to construct an area where the tag is likely to be, similar to a Venn diagram. This thesis proposes a Quality of Positioning system to dynamically and select the best of all available positioning systems for every object to be positioned.This should be trained automatically by ``light vehicles'', such as service pickup trucks, equipped with the hybrid positioning system acting as reference values.Testing was done at the Kristineberg Mine in Västerbotten, Sweden, using a pickup truck equipped with the hybrid positioning system and Wi-Fi personnel positioning tags.It was found that the difference between the two positioning methods was not statistically significant, and that the hybrid positioning system was insufficiently accurate to act as a reference value. This thesis further revealed that the architecture of Mobilaris Mining Intelligence makes implementing a dynamic system impractical.Although planned for, the dynamic Quality of Positioning system was not implemented due to being deemed too impractical, complex and time-consuming compared to the benefit it would have provided.A high-level description of such an implementation is however presented, should it be motivated by future studies.

Full text

Abstract:

Legionella pneumophila is an intracellular bacterium that causes an acute form of pneumonia called Legionnaires' disease. Segregation analyses using macrophages from susceptible and resistant inbred mice previously indicated that a single genetic locus, named Lgn1 , could determine permissiveness to intracellular replication of L. pneumophila. A positional cloning strategy was undertaken, which makes use of genetic and molecular biology techniques to identify the gene responsible for a particular phenotype, based mostly on its location within a chromosome. The work described in this thesis covers three aspects of Lgn1: (1) Building upon the work of others, the Lgn1 genetic interval was narrowed to 0.32 cM within distal mouse chromosome 13. The corresponding 140 Kb Lgn1 physical interval contains only two known transcripts: the Neuronal Apoptosis Inhibitor Protein ( Naip) genes Naip2 and Naip5. (2) The expression profile of the Lgn1 candidates was investigated both at the mRNA and protein levels. Expression of both Naip2 and Naip5 in mouse macrophages strengthened their candidacy for the Lgn1 locus. (3) Transfer of BAC clones from the critical interval into transgenic mice was successfully used to functionally complement the Lgn1 susceptibility phenotype of A/J mice with cloned DNA from non-permissive 129X1 or C57BL/6J origins. Two independent rescuing BAC clones were identified, with a 56-Kb overlap where the entire Lgn1 transcript must lie. The only known full-length transcript coded in this reduced genomic region is Naip5.
Thus, in our last publication we have proposed that Naip5 (recently named Birc1e) is the gene within the Lgn1 locus responsible for differential permissiveness to intracellular L. pneumophila replication in mice.

Abstract:

The hypervariable locus DXS255 in human Xp11.22 has a heterozygosity exceeding 90% and has therefore facilitated the localization of several disease genes which map to the proximal short arm of the X chromosome, including the immune deficiency Wiskott-Aldrich syndrome and the eye disorders retinitis pigmentosa, congenital stationary night blindness and Aland Island eye disease. In addition, a microdeletion involving DXS255 has been identified in patients suffering from Dent's disease, a familial X-linked renal tubular disorder which is characterized by low molecular weight proteinuria, hypercalciuria, nephrocalcinosis, nephrolithiasis (kidney stones) and eventual renal failure. Two YAC contigs were constructed in Xp11.23-p11.22 in order to aid transcript mapping; the first centred on the DXS255 locus, the second mapping distal to the first and linking the genes GATA, TFE3 and SYP to the OATL1 cluster. Eleven novel markers were generated, one of which contains an exon from a novel calcium channel gene. Four putative CpG islands were detected in the region. Analysis of the microdeletion associated with Dent's disease using markers from the DXS255 contig demonstrated that it is confined to a 370kb interval. A YAC overlapping this deletion was hybridized to a kidney-specific cDNA library to isolate coding sequences that might be implicated in the disease aetiology. The clones thus identified detect a 9.5kb transcript which is expressed predominantly in kidney, and originate from a novel gene (CLCN5) falling within the deleted region. Sequence analysis indicates that the 746 residue protein encoded by this gene is a new member of the C1C family of voltage-gated chloride channels. The coding region of CLCN5 is organized into twelve exons, spanning 25-30kb of genomic DNA. Using the information presented in this thesis, other studies have identified deletions and point mutations which disrupt CLCN5 activity in further patients affected with X-linked hypercalciuric nephrolithiasis, confirming the role of this locus in renal tubular dysfunction.

Child phonological processes that lack counterparts in adult phonological typology have long posed a problem for formal modeling of phonological acquisition. This dissertation investigates child-specific processes with a focus on the phenomenon of neutralization in strong position, whereby children preferentially neutralize phonemic contrast in precisely those contexts seen to support maximal contrast in adult systems. These processes are difficult to model without making incorrect predictions for adult typology. Here, it is argued that all genuinely child-specific processes are driven by constraints rooted in child-specific phonetic factors. In a phonetically-based approach to phonology, if there are areas of divergence in phonetic pressures across immature and mature systems, differences across child and adult phonologies are predicted rather than problematic. The phonetically-based approach also explains the developmental elimination of child-specific processes, since in the course of typical maturation, the phonetic pressures driving these effects will cease to apply. Because children's speech-motor control capabilities are known to diverge from those of the skilled adult speaker, it is posited that articulatory factors play the dominant role in shaping child-specific phonological processes. Here it is argued that children have difficulty executing discrete movements of individual articulators, notably the tongue. By moving the tongue-jaw complex as a single unit, the child speaker can reduce the number of degrees of movement freedom and also rely on the action of the motorically simpler mandible to achieve articulatory targets.
(cont.) The effects of mandibular dominance have previously been argued to play a role in shaping sound patterns in babbling and early words (MacNeilage & Davis, 1990). The preference for jaw-dominated movement can be seen to recede over time as the child establishes more reliable articulatory control. However, here evidence from the productions of older children is presented indicating that these effects continue to have an influence in later stages of development than has been previously documented. The pressure to use simultaneous movements of the tongue-jaw complex, formalized in a constraint MOVE-AS-UNIT, is argued to play a role in shaping child-specific processes including positional velar fronting, prevocalic fricative gliding, and consonant harmony. In the present approach, children's tendency to neutralize contrast in strong positions arises as MOVE-AS-UNIT interacts with asymmetries in the force and duration of articulatory gestures across different prosodic contexts. The incorporation of child-specific phonetic factors makes it possible to account for complex patterns of conditioning in child speech processes that would under other assumptions be extremely challenging to model.

Abstract:

The purpose of this study was to examine the prevalence of nystagmus found in healthy individuals during the positional testing subtest of the standard vestibular test battery. Positional testing involves moving the patient's head, and sometimes the entire body, into a variety of positions while observing eye movement. The hypothesis of the current study was that a relatively low percentage of participants would display nystagmus during positional testing used routinely in clinical diagnostic procedures. The findings were then compared to those of an earlier study in which 82% of normal, healthy individuals were reported to exhibit nystagmus during this testing. Twenty-five participants were selected that had no known otologic disease and who reported normal hearing sensitivity. In addition, the participants affirmed they had not consumed any alcohol or taken any medications that are known to affect nystagmus. They were then observed in nine different positions. Forty-eight percent of the participants experienced nystagmus in at least one position. Although this percentage was considerably lower than that reported in the earlier study, methodological differences appear to account for the discrepancy. Specifically, the criterion for determining the presence/absence of nystagmus potentially explains the difference in full.

Abstract:

The facts that relative consumption concerns may give rise both to positional and environmental externalities, and that these two externalities are increasingly transboundary require us to derive an optimal commodity tax in an international framework. The corrective tax policy decided at a national level is found to fail to internalize all positional and environmental externalities. The optimal tax policy under an international cooperative framework reflects correction for both global positional and environmental externalities. In this broader framework, we also characterize the provision of pollution abatement as an additional policy instrument. The results show that relative concerns for one of the private goods do not lead to any modification of the policy rule for public abatement.

Abstract:

Cells and their component structures are highly organised. The correct function of many biological systems relies upon not only temporal control of protein levels but also spatial control of protein localisation within cells. Mathematical modelling allows us to quantitatively test potential mechanisms for protein localisation and spatial organisation. Here we present models of three examples of spatial organisation within individual cells. In the bacterium E. coli, the site of cell division is partly determined by the Min proteins. The Min proteins oscillate between the cell poles and suppress formation of the division ring here, thereby restricting division to midcell. We present a stochastic model of the Min protein dynamics, and use this model to investigate partitioning of the Min proteins between the daughter cells during cell division. The Min proteins determine the correct position for cell division by forming a timeaveraged concentration gradient which is minimal at midcell. Concentration gradients are involved in a range of subcellular processes, and are particularly important for obtaining positional information. By analysing the low copy number spatiotemporal uctuations in protein concentrations for a single polar gradient and two oppositelydirected gradients, we estimate the positional precision that can be achieved in vivo. We nd that time-averaging is vital for high precision. The embryo of the nematode C. elegans has become a model system for the study of cell polarity. At the one-cell stage, the PAR proteins form anterior and posterior domains in a dynamic process driven by contraction of cortical actomyosin. We present a continuum model for this system, including a highly simpli ed model of the actomyosin dynamics. Our model suggests that the known PAR protein interactions 5 are insu cient to explain the experimentally observed cytoplasmic polarity. We discuss a number of modi cations to the model which reproduce the correct cytoplasmic distributions.

Abstract:

This Thesis explores the topic of large amplitude motion within molecular machines and the different mechanisms and molecular architectures that are exploited in order to achieve control over the relative positions of submolecular components with respect to one another. Chapter One provides a thorough survey of a vast range of molecular switches and machines that have been developed during the last two decades. The focus is on interlocked and non-interlocked systems that display highly controlled large amplitude motion and the principles that govern their operation. Initially, simple molecular switches and shuttles are described with the chapter finally arriving at complex molecular machines such as motors, ratchets and walking molecules. The importance of understanding the different mechanisms that dictate the operation of switchable molecular machines and their fundamental differences are highlighted throughout the chapter. Chapters Two to Four are devoted to reporting the author’s contributions to novel switchable molecular systems. Chapter Two describes the serendipitous discovery of an ion-pair template which has been exploited in rotaxane formation and the operation of an orthogonal interaction anion-switchable molecular shuttle. The macrocycle moves back and forth along the thread between a cationic pyridinium station and a metal coordinating triazole motif when chloride anions are bound and removed respectively from a palladium centre which is located inside the cavity of the macrocycle. Excellent positional integrity (>98%) of the ring at both stations is achieved due to the orthogonal binding modes in the two states of the shuttle. Chapter Three presents a non-interlocked molecular switch that operates through the manipulation of dynamic covalent chemistry. The switch is comprised of a “two legged”, small organic molecule (a “walking unit”), anchored to a three foothold track via one disulfide and one hydrazone bond. The acid promoted hydrazone exchange allows a specific ratio of the two positional isomers to be achieved at equilibrium. However, the system is also arranged in such a manner that the ratio can be biased towards one positional isomer when the hydrazone exchange is carried out alongside the photoisomerisation (Z  E) of a stilbene motif which is incorporated in the track. The isomerisation alters the relative free energies of the products by increasing the ring strain of one positional isomer with respect to the other, hence introducing bias into the system. The final chapter reports the logical progression of the work presented in Chapter Three and describes the pursuit of a four-station dynamic covalent energy ratchet, of which the net position of the walker unit can be driven away from a steady state, minimum energy distribution by orthogonal disulfide and hydrazone exchange and concomitant stilbene isomerisation. The endeavour towards the successful synthesis of this rather complex molecule is described alongside the principles for its proposed operation. Chapter Two is presented in the form of an article that has already been published in a peer-reviewed journal. No attempt has been made to rewrite this work other than a slight alteration in the order of figures in the text to allow for easier reading and re-formatting to ensure consistency of presentation throughout this thesis. The original paper is reproduced, in its published format in the Appendix. Chapters Two, Three and Four begin with a synopsis to provide a general overview of the work that is presented in addition to a grateful acknowledgement of the contribution of my fellow researchers.

Abstract:

This thesis researches how the consultant can participate in the creation of successful processes in organizations using multiple theoretical and practical traditions and a pragmatic reflexivity. The research shows how the consultant can do this using a heuristic model developed in the thesis called the consultancy room consisting of three dimensions: distinctions of position, distinctions of system, and distinctions of time. The thesis shows 6 different and distinct positions that the consultant can use in practice: the OD, systemic, solution-focused, appreciative, narrative and strategic position. To show their practical usefulness multiple examples of developing teams are described. The research shows that positions are firstly to be understood as theories that the consultant knows from experience and literature and brings to the organization and secondly the research also shows how such positions are created and coordinated with the customer before and during the consultancy process. The thesis further shows how the consultant can work with multiple distinctions of system. Three prototypical distinctions of system are introduced: the individual, the group, and the organization as part of the consultancy room to help the consultant increase his orientational abilities in practice. And a further distinction between the conversational and the linguistic system is made to help the consultant reflect in and on practice. The conversational system addresses the design of the process by reflecting with the customer about who should talk to whom in order to develop the situation. The linguistic system addresses how the system in focus is being talked about. The thesis shows how the different positions look at and give different possibilities for action in relation to the different distinctions of system. Finally the thesis shows how the consultant can work with multiple distinctions of time. Three prototypical distinctions of time are introduced: the moment, the meeting, and the process as part of the consultancy room to help the consultant navigate in practice. Again the different positions give different ideas of how to act in the moment and how to design meetings and longer processes. The research is done using the researchers own practice as data. A pragmatic research method is created and based in particular on the work of John Dewey (Dewey 1916 1938, Brinkmann 2006) and Gregory Bateson (Bateson 1972 1984)looking at similarities and differences between multiple examples from the researchers practice.
