description: The dependence of flattening of galaxies on the density of galaxies in subclusters selected around galaxies NGC4889, NGC4874 and NGC4839 in the Coma cluster has been studied. The mean values of observed ratios of galaxy diameters and histograms of their distributions indicate that in the central, dense regions of subclusters E and S0 type galaxies are close to spheroidals. Spiral galaxies in subcllusters are found with a hydrogen deficit that about 5 times exceeds the hydrogen deficit in spirals within the halo of the Coma cluster. Most of spirals with a hydrogen deficit in the subcluster around NGC 4874 according to their 3-D coordinates are located closer to the south-east edge of this subcluster near an extended gas filament in the x-ray region. This may indicate over the move of this subcluster toward the central condensation of faint galaxies in the Coma cluster for a possible merge with it.

Extremely Anisotropic Scintillations

description: A small number of quasars exhibit interstellar scintillation on time-scales less than an hour; their scintillation patterns are all known to be anisotropic. Here we consider a totally anisotropic model in which the scintillation pattern is effectively one-dimensional. For the persistent rapid scintillators J1819+3845 and PKS1257-326 we show that this model offers a good description of the two-station time-delay measurements and the annual cycle in the scintillation time-scale. Generalising the model to finite anisotropy yields a better match to the data but the improvement is not significant and the two additional parameters which are required to describe this model are not justified by the existing data. The extreme anisotropy we infer for the scintillation patterns must be attributed to the scattering medium rather than a highly elongated source. For J1819+3845 the totally anisotropic model predicts that the particular radio flux variations seen between mid July and late August should repeat between late August and mid November, and then again between mid November and late December as the Earth twice changes its direction of motion across the scintillation pattern. If this effect can be observed then the minor-axis velocity component of the screen and the orientation of that axis can both be precisely determined. In reality the axis ratio is finite, albeit large, and spatial decorrelation of the flux pattern along the major axis may be observable via differences in the pairwise fluxes within this overlap region; in this case we can also constrain both the major-axis velocity component of the screen and the magnitude of the anisotropy.

description: The aim of this project is to present a history of School nursing. School nursing is an outgrowth of the Visiting Nursing Movement. Modern public health nursing had its inception in Liverpool in 1859. It was under the able leadership of William Rathbone, but it was a direct outcome of the work and teachings of Florence Nightingale. School nursing was the first type of specialization of public health service.

description: People who have serious mental illness experience greater levels of early mortality compared to their mentally healthy counterparts (Chesney, Goodwin & Fazel, 2014). This early death is largely attributed to physical illnesses that are associated with obesity. Individuals who have serious mental illness and who are treated in secure psychiatric hospitals experience significant increases in their weight upon admission. Several factors predispose people with serious mental illness to weight gain and obesity. This thesis explored the factors that mediate weight gain and obesity maintenance in secure psychiatric inpatients. Study 1 used routine patient data to explore changes in body weight following admission into secure services. This established that patient’s body weight on admission was a significant predictor of weight gain over the first twelve weeks of secure inpatient treatment. Study 2 explored the influence of cognitive factors known to influence eating behaviour, the data demonstrated that although the patient group displayed attentional bias to food cues this was not predictive of weight gain. Levels of emotional and disinhibited eating were associated with weight gain over 3 months. Study 3 explored psychological predictors of weight gain; it was found that anxious-preoccupied attachment style was associated with weight gain over 6 months. Study 4 explored staff member’s views on how the secure psychiatric environment impacts on patient weight gain and obesity. A thematic analysis highlighted 5 themes: secure service culture, food culture, poor diet versus lack of physical activity, poor mental health, and weight management initiatives. The results of this thesis are discussed in terms of theoretical perspectives of psychological factors and the wider implications for understanding secure psychiatric inpatient obesity

description: In this work, we discuss the configuration of a gravastar (gravitational vacuum stars) in the context of $f(R, \,T )$ gravity by employing the Mazur-Mottola conjecture [P. Mazur and E. Mottola, Report No. LA-UR-01-5067; P. Mazur and E. Mottola, Proc. Natl. Acad. Sci. USA $101$, $9545$ ($2004$)]. Gravastar is conceptually a substitute for a black hole theory as available in literature and it has three regions with different equation of states. By assuming that the gravastar geometry admits conformal killing vector, the Einstein-Maxwell field equations have been solved in different regions of gravastar by taking a specific equation of state as proposed by Mazur and Mottola. We match our interior spacetime to the exterior spherical region which is completely vacuum and described by Reissner-Nordström geometry. For a particular choice of $f(R,\,T)$ as $f(R, \,T )=R+2γT$, here we analyze various physical properties of the thin shell and also presented our results graphically for these properties. The stability analysis of our present model is also studied by introducing a new parameter $η$ and we explored the stability regions. Our proposed gravastar model in presence of charge might be treated as a successful stable alternative of the charged black hole in the context of this gravity.

How to Develop Trust in the Distrusted Banking System of the Kurdistan Region in Iraq

Publisher: name: Cardiff Metropolitan University
Year: 2022
Subjects: Banking, finance and investment not elsewhere classified

description: This study merged qualitative and quantitative approaches in sequential and equal weight. The primary data collection for this study started with the collection of qualitative data through conducting semi-structured interviews with bank managers and government officials at the ministry of finance in order to identify the main obstacles that they believed faced the current banking system in the KR. Analysis of these results led to the design of a questionnaire survey involving 520 current and potential bank customers to identify the main barriers which cause a continuing lack of trust amongst KR people in the banking system. The study confirmed that the banking system in the KR has either never gained or completely lost the trust of the KR. It has identified several reasons for this including inertia amongst national banks, limited literacy in certain sections of the population and a risk-adverse culture. One of the other major factors preventing the use of banks within the KR is the lack of trust in banks. However, the study has also identified sections of the population who do have a positive interaction with banks, these are mainly younger adults who have been exposed to western banking systems including e-banking.

description: XPOL, the first correlation polarimeter at a large millimeter telescope, uses a flexible digital correlator to measure all four Stokes parameters simultaneously, i.e. the total power I, the linear polarization components Q and U, and the circular polarization V. The versatility of the backend provides adequate bandwidth for efficient continuum observations as well as sufficient spectral resolution (40 kHz) for observations of narrow lines. We demonstrate that the polarimetry specific calibrations are handled with sufficient precision, in particular the relative phase between the Observatory's two orthogonally linearly polarized receivers. The many facets of instrumental polarization are studied at 3mm wavelength in all Stokes parameters: on-axis with point sources and off-axis with beam maps. Stokes Q which is measured as the power difference between the receivers is affected by instrumental polarization at the 1.5% level. Stokes U and V which are measured as cross correlations are very little affected (maximum sidelobes 0.6% (U) and 0.3% (V)). These levels critically depend on the precision of the receiver alignment. They reach these minimum levels set by small ellipticities of the feed horns when alignment is optimum (

Wildfire
California

description: As of 2018, more than 11 million Californians (about 25%) lived in Wildland Urban Interface areas (WUI). The WUI is an area where homes intermix with flammable landscape (California Department of Housing and Community Development 2020). These areas are fire-prone and have experienced larger and faster-growing fires in recent years. One of the most catastrophic of these fires is the Camp Fire, which struck Butte County in Northern California in late 2018. Fire professionals have pushed to increase mitigation actions such as thinning forests and using pre-planned small-scale burns. However, it is difficult to know where the next fire disaster will occur. It is therefore important to identify the areas in which people may have the hardest time recovering and plan better for when the fire arrives. In this Professional Report, I use existing literature to investigate the comprehensive damage borne out of the Camp Fire. Understanding these numerous and often linked impacts in housing, water contamination, health care impacts and others can inform future iterations of mitigation plans. I utilize a social vulnerability index, which identifies various Census data variables that can hinder disaster response and recovery, to assess the intersections of areas of high fire risk and high social vulnerability in Butte County. This research is important because although many communities are exposed to wildfire risk, people considered more socially vulnerable suffer disparate impacts, which include a hindered ability to respond to and recover from these conflagrations (Cutter & Finch 2008). Some of the impacts that came up in the recovery process include meeting gaps in supply for medical care, schools and housing. I hope some of these less publicized impacts can be addressed in the mitigation plans of Butte County and other jurisdictions moving forward. I found that the General Plan was not nuanced enough and did not address many of the complex risks that came about during the tragic Camp Fire. Plans need to become more specific so that implementation measures can be effectively evaluated and modified to improve their effectiveness. Most Butte County census tracts are more socially vulnerable than the majority of census tracts in California. Mitigation actions should look at specific demographics for which Butte County residents are especially vulnerable. Specific SVI variables to be concerned about include high concentrations of elderly residents, people with disabilities and lack of access to quality housing and transportation options. Many of these demographic characteristics can be disrupted greatly by events such as wildfires or even the power shut-offs that come with high fire danger days.

description: The rate and nature of speech development in children is influenced by a range of biological and linguistic factors. Construction and mastery of the phonological system, or systems, is underpinned by implicit and explicit learning mechanisms with the structure and content of the language input received providing a basis for this process (Vihman and Croft, 2007). For children living in Wales, there is a lack of information available on the trajectory of early Welsh and English speech development. A small number of studies have reported on the speech development of Welsh-English bilingual children (Mayr, Howells and Lewis, 2015; Mayr, Jones and Mennen, 2014; Munro et al., 2005). However, none of these have included data on children younger than 2;6 nor those who are not following the expected developmental trajectory.
 The aim of this study was to investigate the trajectory of early speech development among children from a Welsh-English bilingual community in North Wales. Longitudinal data collected from six children were analysed in relation to the production of consonants and word shapes. Data collection took place at eight-week intervals, starting at 13 months and continuing until the end of the single-word stage, a duration of up to 18 months. Children from single- and dual-language homes were video recorded whilst interacting with a parent during play. Their vocalisations were identified, transcribed and evaluated in relation to the range and prevalence of the consonants and word-shapes they contained. Whole-word templates were identified which allowed for conclusions to be drawn in relation to the emergence of (a) phonological system(s) (Vihman, 2017).
 The results revealed between- and within-child cross-linguistic similarity in the production of consonants across Welsh and English language environments. Ambient language influence was found, however, in the structural properties of the words targeted and the children’s production attempts. Both lexicon and consonant inventory growth was seen over time, but close inspection of the data revealed that the speech development of one child was different to the others, and therefore labelled atypical. Research to date on atypical bilingual speech has been limited to those over 3;0. This study therefore provides the first systematic account of early atypical speech development in a bilingual child. For children experiencing societal bilingualism, establishing the developmental trajectory, as well as identifying the role of the ambient language, has far-reaching clinical and theoretical implications.

description: Dans sa forme conventionnelle, l’imagerie ultrasonore focalisée, la cadence d’image est limitée à quelques dizaines d’images par seconde. Durant les deux dernières décennies, l’imagerie ultrasonore a connu une véritable révolution avec l’apparition de l’imagerie dite ultrarapide, permettant d’imager avec une cadence d’image de plusieurs milliers d’images par seconde. Cette augmentation de la cadence d’image a permis l’émergence de nouveaux modes d’imagerie tels que l’imagerie fonctionnelle ou paramétrique, proposant de nouveaux outils de diagnostic pour les cliniciens. Cependant, toutes les méthodes d’imagerie ultrasonore ultrarapide souffrent d’un compromis entre cadence et qualité d’image.

Dans ce contexte, l’objectif principal de cette thèse est de développer des méthodes d’acquisition et de reconstruction d’images ultrasonore permettant d’optimiser la cadence d’image sans dégradation de la qualité. Pour cela, les émissions codées, dérivées des télécommunications et de l’imagerie RADAR, sont utilisées. L’axe principal de cette thèse concerne l’augmentation de la cadence d’image en imagerie ultrasonore par synthèse d’ouverture (STA). Classiquement, cette méthode d’imagerie permet d’atteindre une grande qualité d’image mais souffre d’une cadence d’image réduite. Le principe développé dans cette thèse consiste à activer simultanément plusieurs émetteurs en appliquant un encodage spatio-temporel à ces derniers. En utilisant cette méthode, nous montrons qu’un gain en cadence d’image d’un facteur 5 peut être atteint lors d’acquisitions expérimentales, sans dégradation de la qualité d’image. Un second axe investigué dans cette thèse consiste à augmenter la cadence d’image en imagerie par ondes planes (PWI) par l’émission simultanée de plusieurs ondes planes codées. Le modèle direct est décrit et utilisé pour résoudre le problème inverse associé afin de reconstruire le milieu imagé. Nous montrons que cette méthode permet d’améliorer simultanément la cadence et la qualité d’image lors d’acquisitions expérimentales.

description: We present a generalized approach for computing electron conductance and I-V characteristics in multiterminal junctions from first-principles. Within the framework of Keldysh theory, electron transmission is evaluated employing an O(N) method for electronic-structure calculations. The nonequilibrium Green function for the nonequilibrium electron density of the multiterminal junction is computed self-consistently by solving Poisson equation after applying a realistic bias. We illustrate the suitability of the method on two examples of four-terminal systems, a radialene molecule connected to carbon chains and two crossed carbon chains brought together closer and closer. We describe charge density, potential profile, and transmission of electrons between any two terminals. Finally, we discuss the applicability of this technique to study complex electronic devices.

Predicting the effect of vertical pipe orientation by the method of characteristics during sudden discharge of a two-phase fluid
Creators: name: Mazaffari-Nejad, Hooshang
Publisher: name: University of British Columbia
Year: 2010

description: Present research was undertaken to study the effect of pipe orientation during discharge of saturated water through a sudden opening. Analytical investigations have been made for various ranges of initial pressure, including high pressures previously studied by others. A 4 m long 32 mm in diameter pipe has been used entirely for this investigation to facilitate comparison with available experiments. When the initial pressure in the pipe was just slightly above atmospheric, body forces were obviously expected to play an important role. The effect became especially pronounced when directly comparing upflow versus downflow. Even at higher pressures, it has been seen in flow visualization experiments that the flow becomes stratified in a horizontal pipe. When the pipe is oriented vertically (up or down), this will no longer be true since turbulent mixing occurs. The research was undertaken because of its direct relevance to the loss-of-coolant accident (LOCA). In order to obtain licenses for operating reactors, certain safety standards oust be met. The reactor must be shown to be safe in normal operation as well as in the case of a hypothetical accident. Different models have been used to analyze the LOCA, simplest of which is the equal velocity-equal temperature (EVET) model, which considers both phases in equilibrium at all times. the EVET model (used entirely in this work) was thought to be a good model for vertical flow. Several, computations were made using the method of characteristics to study the effect of gravity on pressure and void fraction histories at the closed end. Void fraction, the ratio of vapor area to pipe area at any cross section, was investigated because of its direct relevance to mixture density and speed of sound. Also, total discharge or mass flow rate, a combined measure of density and velocity, was calculated at the open end. Runs were made for water at initial pressures of 1.2, 1.8, and 35 atm (at the top of the pipe). All cases started just at saturation with a small void fraction of .001 in a 4 m long .032 m diameter pipe (Figure 1). The hydrostatic head of water column exerting an approximate pressure of 40000 Pa was comparable to the former pressures, but quite different from the latter of 35 atm. For 1.2 atm., or .12 MPa, the ratio of gravity force to pressure force (reciprocal of Froude number times Euler number) defined as "3P" was about 33%; it was 25% for the .18 MPa case, and only 1.1 % for the case when initial pressure was 3.5 MPa. The "3P" ratio was shown to be an important measure of the gravity effect. When GP=1.1%, there was negligible difference between the pressures along the pipe for the upflow and downflow case- In both lower initial pressure cases, however, there seemed to be a clear difference between the pressures for upflow and downflow at the closed end.

description: Hall effect and magnetoresistance have been measured on single crystals of $NdFeAsO_{1-x}F_{x}$ with x = 0 ($T_c$ = 0 $ $K) and x = 0.18 ($T_c$ = 50 $ $K). For the undoped samples, strong Hall effect and magnetoresistance with strong temperature dependence were found below about 150 K. The magnetoresistance was found to be as large as 30% at 15 K at a magnetic field of 9 T. From the transport data we found that the transition near 155 K was accomplished in two steps: first one occurs at 155 K which may be associated with the structural transition, the second one takes place at about 140 K which may correspond to the spin-density wave like transition. In the superconducting sample with $T_c$ = 50 $ $K, it is found that the Hall coefficient also reveals a strong temperature dependence with a negative sign. But the magnetoresistance becomes very weak and does not satisfy the Kohler's scaling law. These dilemmatic results (strong Hall effect and very weak magnetoresistance) prevent to understand the normal state electric conduction by a simple multi-band model by taking account the electron and hole pockets. Detailed analysis further indicates that the strong temperature dependence of $R_H$ cannot be easily understood with the simple multi-band model either. A picture concerning a suppression to the density of states at the Fermi energy in lowering temperature is more reasonable. A comparison between the Hall coefficient of the undoped sample and the superconducting sample suggests that the doping may remove the nesting condition for the formation of the SDW order, since both samples have very similar temperature dependence above 175 K.

description: Routinely, Platelet Concentrates (PC) are stored at 22±2oC, constantly agitated, for up to 7 days with constant bacterial monitoring. Storage conditions stemmed from historical studies and have not differed substantially, despite advances in knowledge and technology. Extracellular vesicles (EVs) are small membrane bound vesicles released from all cells and their roles include cell-to-cell communication. EVs are present within PC, however their actions and roles upon reinfusion is unknown. The aim of this thesis was to assess EVs within PC storage and to optimise the external storage environment to improve platelet function and quality overtime, with the potential to increase storage duration. For this purpose, use of cold storage (4±2oC) and differential oxygen environments were investigated. EVs extracted from PC were characterised using Nanosight tracking analysis and flow cytometry. Direct measurements of oxygen concentration within the storage container and oxygen consumption of platelets was assessed by electron paramagnetic resonance oximetry. Impedance platelet aggregometry was used to assess platelet function. Results from cold storage indicated that platelet aggregometry was not significantly improved compared to conventional storage, however a significant increase in pro-coagulant EV numbers was observed during cold storage which could result in a shortened bleeding time if transfused. A significant finding was oxygen availability in the bag was limited even when incubated at 21% oxygen under standard conditions. Applying the direct measurements made to a mathematical model demonstrated large areas of hypoxia at a relatively short distance from the surface of the container. To address this, predicted by the model, two approaches were taken: reducing platelet concentration or increasing external oxygen concentration. Platelet quality was increased, although elevated oxygen levels gave rise to oxidative stress. This work has provided a new understanding of factors which limit PC storage and point the way forward to improving platelet quality.

description: As the empirical literature on Instagram is still in its early stages, current insights into the application and its potential effects on users are still far from comprehensive. Given the growing popularity of Instagram during the ongoing pandemic, the present study aims to contribute to a more nuanced understanding of Instagram use and its associations with user characteristics and well-being by examining an as of yet unstudied aspect of Instagram use. Specifically, we aim to explore what motivations underly the use of public and private Instagram accounts respectively, as well as potential associations with specific usage patterns, personality and psychological traits, demographic variables, and previous experiences of cyberbullying and online discrimination. Furthermore, as only a small number of studies has investigated Instagram use and associations to well-being over time, the present study intends to explore the longitudinal associations between the regular use of private versus public Instagram accounts with subjective well-being.

description: We consider one-dimensional discrete-time random walks (RWs) in the presence of finite size traps of length $\ell$ over which the RWs can jump. We study the survival probability of such RWs when the traps are periodically distributed and separated by a distance $L$. We obtain exact results for the mean first-passage time and the survival probability in the special case of a double-sided exponential jump distribution. While such RWs typically survive longer than if they could not leap over traps, their survival probability still decreases exponentially with the number of steps. The decay rate of the survival probability depends in a non-trivial way on the trap length $\ell$ and exhibits an interesting regime when $\ell\rightarrow 0$ as it tends to the ratio $\ell/L$, which is reminiscent of strongly chaotic deterministic systems. We generalize our model to continuous-time RWs, where we introduce a power-law distributed waiting time before each jump. In this case, we find that the survival probability decays algebraically with an exponent that is independent of the trap length. Finally, we derive the diffusive limit of our model and show that, depending on the chosen scaling, we obtain either diffusion with uniform absorption, or diffusion with periodically distributed point absorbers.

description: Oscillations represent a ubiquitous phenomenon in biological systems. The conventional models of biological periodic oscillations are usually proposed as interconnecting transcriptional feedback loops. Some specific proteins function as transcription factors, which in turn negatively regulate the expression of the genes that encode those "clock protein". These loops may lead to rhythmic changes in gene expression of a cell. In the case of multi-cellular tissue, the collective oscillation is often obtained from synchronization of these cells, which manifest themselves as autonomous oscillators. In contrast, here, we propose a different scenario for the occurrence of collective oscillation in a multi-cellular system independent of oscillation, neither intrinsically oscillatory cells nor periodic external stimulation. It is a coupling induced oscillation, with the consideration of wave propagation due to the intracellular communication.

Trampoline-gymnasts' embodied lives: An ethnographic study

description: Gymnastic bodies have been a relatively 'absent presence' in the literature. Despite patterns of problematic body issues (e.g., weight-control behaviours, body dissatisfaction and low self-esteem) highlighted in elite artistic and rhythmic gymnasts, and national governing body recognition of these issues, we know very little about their embodied lives and even less about the experiences of trampoline-gymnasts. Thus, this work aimed to explore the embodied lives of trampoline-gymnasts as they progressed through their trampoline career.
 An ethnographic study was conducted within one trampoline club over a period of 17 months. Thirty-six trampoline-gymnasts aged 6-21 years old took part, providing rich, stories of individuals' lives in and through various points of their trampoline career. An embodied narrative approach permeated the research design, framing the research aim and objectives, data collection, analysis and representation. An analytical focus on narrative structures within trampoline-gymnasts' stories produced ideas about how these young people narratively constructed and understood their embodied lives. Ultimately, over the course of their career, trampoline-gymnasts had little autonomy in making decisions about their sporting lives, particularly when choosing to enter and remain in the trampoline club. Coaches were key gatekeepers in selection and recruitment processes and parents decided if their children would join and remain in the club. Moreover, trampoline and gymnastic discourses restricted the types of bodies constructed in this group and impacted upon the ways in which their bodies were experienced. Options for retirement were also constrained by a limited number of narratives for preferred future selves and identities. Yet, being in this group gymnasts formed a sense of belonging and accomplishment which was long-lasting and engrained in the body-selves and identities they constructed.
 Collectively, the research findings have provided an understanding of trampoline-gymnasts' embodied lives over the course of their career. A model of embodied careers in sport has been created, illustrating how trampoline-gymnasts' embodied experiences are narratively constructed and understood over time. Importantly, this work has given them a voice. Their storied experiences provide a potential platform for change, ensuring healthy and prolonged participation in this and other gymnastic disciplines.

description: Spontaneous CP-violation in the strong interaction is analyzed at theta = pi within the framework of the two-flavor NJL model. It is found that the occurrence of spontaneous CP-violation at theta = pi depends on the strength of the 't Hooft determinant interaction, which describes the effect of instanton interactions. The dependence of the phase structure, and in particular of the CP-violating phase, on the quark masses, temperature, baryon and isospin chemical potential is examined in detail. When available a comparison to earlier results from chiral perturbation theory is made. From our results we conclude that spontaneous CP-violation in the strong interaction is an inherently low-energy phenomenon. In all cases we find agreement with the Vafa-Witten theorem, also at nonzero density and temperature. Meson masses and mixing in the CP-violating phase display some unusual features as a function of instanton interaction strength. A modification of the condition for charged pion condensation at nonzero isospin chemical potential and a novel phase of charged a_0 mesons are discussed.

Finding Our Way: A Socio-Cultural Exploration of Wayfinding as an Embodied Experience
Creators: name: Symonds, Paul A.
Publisher: name: Cardiff Metropolitan University
Year: 2022
Subjects: Sociology not elsewhere classified

description: The focus of this study is 'Wayfinding', a practice that is concerned with how we find our way between places. To date, the majority of research on wayfinding has used a psychological lens, placing a significant focus on wayfinding as a cognitive practice and using quantitative data and a realist approach. At the time of writing, no study has focused on researching wayfinding from a sociological perspective1 that places the body at the centre of wayfinding practice. This study moves beyond the psychological approaches to provide a more holistic understanding of wayfinding.
 Twenty-three in-depth qualitative interviews took place in order to investigate and to try and better understand wayfinding from a socio-cultural perspective with consideration for wayfinding as an embodied experience. Volunteers were purposefully chosen in order to represent a diverse range of wayfinding situations including commuting, holiday purposes, as part of a job or for everyday needs such as to go shopping. The data are represented thematically, using Weberâ€™s (1964) concept of ideal types and the discussion of the data is shaped using a range of concepts from the work of Tim Ingold, Erving Goffman and Pierre Bourdieu.
 A number of unique themes emerge from the data, showing wayfinding to be an embodied socio-cultural experience that is heterogeneous and heuristic in nature and that is rarely a linear activity, as suggested by authors such as Haque, Kulik and Klippel (2007), HÃ¶lscher, Tenbrink and Wiener (2011) and Tam (2011), who all describe wayfinding as being about getting from A to B via the quickest or shortest possible route.
 From the data, it becomes clear that wayfinding is rarely, if ever, an individual practice or one that is simply based on cognitive processes. The larger implications of this study are that, by better understanding wayfinding as a fully embodied and socio-cultural practice, new ways of planning and conceptualising the design of wayfinding systems and practices should be considered.
