Effective automated tracking and locating of the thousands of materials on construction sites improves material distribution and project performance and thus has a significant positive impact on construction productivity. Many locating technologies and data sources have therefore been developed, and the deployment of a cost-effective, scalable, and easy-to-implement materials location sensing system at actual construction sites has very recently become both technically and economically feasible. However, considerable opportunity still exists to improve the accuracy, precision, and robustness of such systems. The quest for fundamental methods that can take advantage of the relative strengths of each individual technology and data source motivated this research, which has led to the development of new data fusion methods for improving materials location estimation. In this study a data fusion model is used to generate an integrated solution for the automated identification, location estimation, and relocation detection of construction materials. The developed model is a modified functional data fusion model. Particular attention is paid to noisy environments where low-cost RFID tags are attached to all materials, which are sometimes moved repeatedly around the site. A portion of the work focuses partly on relocation detection because it is closely coupled with location estimation and because it can be used to detect the multi-handling of materials, which is a key indicator of inefficiency. This research has successfully addressed the challenges of fusing data from multiple sources of information in a very noisy and dynamic environment. The results indicate potential for the proposed model to improve location estimation and movement detection as well as to automate the calculation of the incidence of multi-handling.

The main purpose of this essay is to through theories about internal communication, channels to communicate through and change management study how these can be related to the processes at the Swedish Consumer Agency due to its future relocation. The main question within this essay is therefore: - How has the internal communication and the change management at the Swedish Consumer Agency developed in comparison with the prescribed theories? This essay is divided into three different parts (ideal, reality, ideal/reality) which can be derived to the essays theory, result and analysis chapters. The theories are the ideal while the result describes the internal communication and the change management during the process (the reality). In the analysis chapter, the ideal and the reality are compared to distinguish how the reality has been working in comparison to the ideal. The internal communication has mainly been distinguished through the authority’s intranet and the information communicated has comparatively been fast, open, objective and reliable. One of the prerequisites for this is that the authority has been permeated by clear goals and visions. All in all the result shows that the internal communication and the change management have been successful but some flaws have been detected. One of the reasons for this might be that the authority and its co-workers have been exposed in the process due to the fact that it has been enforced and because of its extent. / Det övergripande syftet med föreliggande undersökning är att utifrån teorier om internkommunikation, kommunikationskanaler och förändringsarbete undersöka hur dessa kan sättas i relation till den förändringsprocess som genomförts på Konsumentverket inför dess framtida omlokalisering. För att undersöka detta kommer följande frågeställning behandlas: - Hur har Konsumentverkets internkommunikation och förändringsarbete fungerat i jämförelse med de teorier som ligger till grund för uppsatsen? Undersökningen består av tre delar (ideal, verklighet, ideal/verklighet) vilka kan härledas till uppsatsens teori-, resultat- och analyskapitel. De teorier uppsatsen bygger på behandlas som idealet medan undersökningens resultat beskriver hur internkommunikationen och förändringsarbetet fungerat i verkligheten. I uppsatsens analys ställs dessa mot varandra för att urskilja verkligheten i relation till idealet. Den huvudsakliga internkommunikationen har skett via myndighetens intranät och den information som förmedlats under processen har varit förhållandevis snabb, öppen, saklig och trovärdig. En av förutsättningarna för detta kan ha varit att myndigheten genomsyras av tydliga mål och visioner. Sammantaget har processen varit framgångsrik men vissa brister i kommunikationen har påträffats. Detta kan delvis bero på att myndigheten och dess medarbetare haft en utsatt roll i processen då förändringen varit påtvingad av yttre faktorer samt att den varit mycket omfattande.

The study was conducted in the community of Wellbedacht East in eThekwini Municipality. Welbedacht East (WE) is located north-east of Umlazi Township and west of Chatsworth and also expands into the eNgonyameni Traditional Authority. WE is about 23 kilometres from Pinetown, 43 kilometres from Durban, and 15 kilometres from Chatsworth Centre. It is one of the development projects undertaken to spearhead the very ambitious programme of slums clearance, in order to confront the challenge of informal settlements in the eThekwini Municipal area. The study area has been chosen because it is one of the largest slum clearance projects in eThekwini Municipality (Durban) and it is peripherally located. Due to its peripheral location, transport services, and facilities such as schools, a clinic, a police station, churches and shops are either scarce, or non-existent. A systematic sample of 60 households was drawn from a population of residents whose characteristics had been considered to reflect those of the larger population. The project has 5000 sites and 3000 beneficiary households were relocated to this project from the inner city areas. The study is aimed at examining the impact and effects of relocation on beneficiary households in peripherally located low-income housing projects, to determine whether or not transport costs are higher in peripherally situated settlements than in more central locations, and whether residents in peripheral settlements are less able to access the benefits of urban living, including economic opportunities and social networks necessary for survival. It argues that the relocation of informal settlements to peripheral sites promotes an urban sprawl, and thus deviates from the eThekwini Municipality's goal of promoting development as a 'compact city'. The findings in this study are that, firstly, there is clear evidence to suggest that relocations to peripheral areas can cause significant harm to relocated beneficiary households' livelihood strategies, and secondly, that the municipality's failure to coordinate its relocations plan with other spheres of government involved with social service delivery, especially the departments of health and education, resulted in medium-term deprivation of access to social services. The conclusions drawn from the findings are that a holistic and integrated approach to housing development needs to be enforced, whereby the minimum facilities, such as schools, clinics and other social amenities are prioritised if the project is poorly located. The study therefore recommends that low-income housing projects be located closer to the economic nodes, in order to eliminate transport costs and other social difficulties associated with peripheral location. The compact city settlement design epitomised by higher residential densities and the development of multifunctional habitats would, to a greater extent, reduce the need to travel, and improve quality of life and access to urban goods and services. / Thesis (M.T.R.P.)-University of KwaZulu-Natal, 2006.

This study explores the government's current land refonn programme in the light of nation building. It is hypothesised that though the government means well by its introduction of the programme, the current land refonn policy will negatively affect race relations. This is due to the fact that the introduction of this policy has exacerbated white fears of dispossession and raised black expectations of redress. Therefore, the success of this policy will exacerbate white dissatisfaction, and the failure of the policy will frustrate black expectations. Nevertheless, it is argued that this is only prevalent in the short run where as in the long run nation building could be achieved through this programme. / Thesis (M.Soc.Sci.)-University of Natal, Pietermaritzburg, 2002.

Weißbüschelaffen (WBA) sind wissenschaftlich häufig genutzte Modelltiere für diverse Humanerkrankungen. Zur Gesunderhaltung dieser Primaten sind grundlegende diagnostische Blutparameter unverzichtbar. Bisher erhobene Daten zeichneten sich jedoch durch große Divergenz aus. Ob Veränderungen in Haltungsbedingungen einen Einfluss auf diese Blutparameter nehmen, ist bis heute unklar. Somit war ein Ziel dieser Arbeit die Erhebung aktueller hämatologischer und klinisch-chemischer Blutparameter von WBA. Zudem wurde der Einfluss der routinemäßigen Umsetzung in eine neue Behausung auf die erhobenen Parameter sowie den Kortisolspiegel im Kot untersucht. Des Weiteren leiden WBA in menschlicher Obhut rezidivierend an gastrointestinalen Erkrankungen, die mittels klinischer Standardparameter allein nicht diagnostizierbar sind. Dabei spielt vor allem die Sensitivität gegenüber Futtermittelinhaltsstoffen (z. B. Gluten) eine Rolle, welche ursächlich im Zusammenhang mit dem Wasting Marmoset Syndrome (WMS) diskutiert wird. Im zweiten Teil der vorliegenden Arbeit sollten deshalb die gastrointestinalen Erkrankungen von in menschlicher Obhut lebenden WBA ätiologisch beleuchtet werden, vor allem hinsichtlich einer möglichen Sensitivität gegenüber Gluten. Im ersten Teil dieser Studie wurden von 54 WBA hämatologische und klinischchemische Richtwerte erhoben. Die ermittelten hämatologischen Blutrichtwerte ähneln denen aus den achtziger Jahren, die Daten der klinischen Chemie nur bedingt: Die Richtwertbereiche von Laktatdehydrogenase, Alaninaminotransferase, Lipase sowie Alkalische Phosphatase und Gesamtbilirubin weichen von den ehemals erhobenen Daten ab. Zudem wurden in der vorliegenden Arbeit geschlechtsabhängige Unterschiede ermittelt: Weibliche Tiere wiesen signifikant höheres mittleres Erythrozytenvolumen und mittleren Hämoglobingehalt des Einzelerythrozyten auf als männliche Tiere, wohingegen bei diesen ein signifikant höheres Gesamt- und Low density lipoprotein- Cholesterol im Vergleich zu weiblichen Affen messbar war. Des Weiteren wurden 16 Tiere über einen vierwöchigen Zeitraum in eine neue Umgebung verbracht, bevor sie in ihre Heimatbehausung zurückkehrten. Durch diese Umsetzung war bei den untersuchten Tieren die Leuko- und Lymphozytenzahl auch vier Wochen nach der Umsetzung erniedrigt. Zeitgleich lag ein erhöhter Kortisolspiegel vor, der im Kot bestimmt wurde. Im zweiten Teil der Studie wurden anhand humandiagnostischer Standards IgAAntikörper (AK) gegen Gliadin (AGA), Gewebstransglutaminase (tTG), deamidiertes Gliadin (ADGA) sowie Glykoprotein 2 (AGP2A) im Plasma von 24 WBA mittels eines ELISAs während glutenhaltiger (Diät 1) und glutenfreier Ernährung (Diät 2) bestimmt. Dabei wurden die klinische Symptomatik von WMS und das Körpergewicht der Tiere ebenfalls untersucht. Zudem erfolgte die Analyse von Kotproben antikörperpositiver Tiere hinsichtlich Qualität und Trockenmassegehalt während Diät 2 und einer darauf folgenden glutenhaltigen Provokationsdiät. Die serologische Diagnostik ergab einen signifikanten Rückgang von AGA, AK gegen tTG und AGP2A während Diät 2 bei Tieren, die nach Diät 1 erhöhte Werte aufwiesen. Diät 2 führte zu einem Rückgang der klinischen Symptome und einer signifikanten Gewichtszunahme bei antikörperpositiven WBA. Die glutenhaltige Provokationsdiät ergab eine verminderte Kotqualität mit einem niedrigeren Trockenmassegehalt. Es wurden im Rahmen dieser Arbeit aktuelle, hämatologische und klinisch-chemische Blutrichtwerte des WBA erhoben. Der durch Umsetzung in eine neue Behausung bedingte Stress ist bei WBA bis vier Wochen lang nachweisbar. Es ist sinnvoll, dies in der zeitlichen Planung wissenschaftlicher Studien zu berücksichtigen, um das Wohlbefinden der Tiere vor Versuchsbeginn sicherzustellen und den Einfluss von Stress auf experimentelle Ergebnisse zu minimieren. Der Nachweis grundlegender, an der Pathogenese der Zöliakie beteiligter Antikörper, in Kombination mit den klinischen Symptomen, deutet auf Glutensensitivität mit ätiologischer Beteiligung an WMS bei WBA hin. Die glutenfreie Ernährung von WBA in menschlicher Obhut ist daher sinnvoll und empfehlenswert. / Common marmosets are often used as animal models for human diseases. For their health maintenance, diagnostic blood values are absolutely essential. Previously obtained reference values are characterized by great value-specific differences. Moreover, the influence of routine measures on these blood parameters, e. g. changes in housing conditions, has not been examined yet. Therefore, the first aim of the present study was to update haematological and clinical chemical blood parameters of common marmosets. Further, the influence of stress, caused by relocation to a new housing, on these parameters and the cortisol level in feces was examined. In addition to that, common marmosets under human management are often affected by gastrointestinal diseases, which are difficult to diagnose with basic standard blood values. In this context, sensitivity to nutritional elements, e. g. gluten, plays an important role and is discussed as a potential cause of wasting marmoset syndrome (WMS). In the second part of this study, the recurrent gastrointestinal diseases of common marmosets under human management were aetiologically investigated, with special regard to possible gluten sensitivity. In the first part of this study, blood samples were obtained from 54 female and male common marmosets to evaluate standard values of haematology and clinical chemistry. The determined haematological parameters are similar to the already obtained data, the clinical chemistry values differ somewhat: The enzyme activities of lactate dehydrogenase, alanine aminotransferase and lipase in addition to the ranges of alkaline phosphatase and total bilirubin diverge from the data ascertained in this study. Moreover, female animals presented significantly higher mean corpuscular volume and mean corpuscular haemoglobin than males, whereas male common marmosets showed significantly higher total- and low density lipoprotein-cholesterol, compared to females. Further, 16 animals were relocated to a new environment for a time period of four weeks, before they returned to their home cages. The change of housing caused a decreased leuko- and lymphocyte count in all examined animals that was still measurable four weeks after the relocation. At the same time, an increased fecal cortisol level was determined. The aim of the second study was to investigate the modification of plasma antibodies to gliadin (AGA), tissue transglutaminase (tTG), deamidated gliadin (ADGA) and glycoprotein 2 (AGP2A) during two successive diets in 24 animals: A gluten-containing diet (diet 1) and a gluten-free diet (diet 2). Further, clinical symptoms of WMS and the animals’ body weight were also examined. An analysis of the feces of antibody-positive animals regarding changes in quality and dry matter content was carried out with samples collected during diet 2 and a successive gluten challenge diet of two months duration. The serological diagnostics resulted in a significant decline of AGA, antibodies to tTG and AGP2A during diet 2 in animals that had shown increased antibody concentrations during diet 1. Diet 2 also caused an amelioration of clinical symptoms and an increased body weight in antibody-positive animals. The gluten challenge resulted in a decreased feces quality and a lower fecal dry matter, compared to fecal samples of diet 2. In the context of this dissertation, parameters of haematology and clinical chemistry of the common marmoset were updated. Stress caused by relocation to a new housing was still measurable for a period of four weeks. It is therefore essential to consider this time span in the design of scientific studies to secure animal welfare prior to the study and to reduce the influence of stress on experimental results. In combination with the clinical symptoms, the detection of antibodies that are part of the pathogenesis of coeliac disease in humans strongly suggests gluten sensitivity with an aetiological connection to WMS in common marmosets. Therefore, gluten-free nutrition of common marmosets under human management is highly recommendable.

During 2010 and 2011, a series of major earthquakes caused widespread damage in the city of Christchurch, New Zealand. The magnitude 6.3 quake in February 2011 caused 185 fatalities. In the ensuing months, the government progressively zoned residential land in Christchurch on the basis of its suitability for future occupation (considering damage from these quakes and future earthquake risk). Over 6,000 homes were placed in the ‘red-zone’, meaning that property owners were forced to sell their land to the Crown. This study analysed patterns of residential mobility amongst thirty-one red-zone households from the suburb of Southshore, Christchurch. Drawing on interviews and surveys, the research traced their experience from the zoning announcement until they had moved to a new residence. The research distinguished between short (before the zoning announcement) and long term (post the red zone ‘deadline’) forms of household relocation. The majority of households in the study were highly resistant to short term movement. Amongst those which did relocate before the zoning decision, the desire to maintain a valued social connection with a person outside of the earthquake environment was often an important factor. Some households also moved out of perceived necessity (e.g. due to lack of power or water). In terms of long-term relocation, concepts of affordability and safety were much more highly valued by the sample when purchasing post-quake property. This resulted in a distinct patterning of post-quake housing location choices. Perceived control over the moving process, relationship with government organisations and insurance companies, and time spent in the red-zone before moving all heavily influenced participants’ disaster experience. Contrary to previous studies, households in this study recorded higher levels of subjective well-being after relocating. The study proposed a typology of movers in the Christchurch post-disaster environment. Four mobility behaviours, or types, are identified: the Committed Stayers (CSs), the Environment Re-Creators (ERCs), the Resigned Acceptors (RAs), and the Opportunistic Movers (OMs). The CSs were defined by their immobility rather than their relocation aspirations, whilst the ERCs attempted to recreate or retain aspects of Southshore through their mobility. The RAs expressed a form of apathy towards the post-quake environment, whereas, on the other hand, the OMs moved relative to pre-earthquake plans, or opportunities that arose from the earthquake itself. Possibilities for further research include examining household adaptability to new residential environments and tracking further mobility patterns in the years following relocation from the red- zone.

The social displacement enforced by the South African Group Areas Act between 1954 and 1955 was understandably experienced as a destructive process with physical and emotional consequences arising from various types of losses, separation and feelings of helplessness. Although the forced removals affected all the people in the community - also in later years and generations, it seems as if older people are affected the more as they still remember the losses they experienced when they were removed from their homes and their communities, when their heritage and their culture were displaced. The sense of belonging being experienced by older people, who were subjected to these forceful removals, is therefore unclear. In this study the sense of belonging is defined as the effective participation, involvement, contribution and emersion of people when relating to their social, physical, spiritual, emotional and cultural places. In this study older (aged 60 and above) Setswana speaking residents of Ikageng, a community just outside Potchefstroom in the North West Province, South Africa, who were also forcibly relocated from Kloppersville to Ikageng, 10 kilometers away from Kloppersville, were asked to identify places that are important to them in Ikageng and to describe the meanings they attach to these places. In the research, no one identified any places of importance in Ikageng, instead throughout the research they kept on referring to their lives in Kloppersville, their former place of residence, the place where they were forcibly removed from – giving purpose and direction to this study and leading to the question: What are the experiences related to the sense of belonging of Setswana speaking older women who were forcibly relocated during Apartheid in South Africa? The older persons’ experiences of their sense of belonging in the place where they were forcibly relocated to must be understood in relation to the past. A qualitative research approach was used and a narrative research design followed. Two sets of data were gathered and are reported on in this article that focuses on the narrations of 11 older Tswana people from the Day Care Centre for the Aged in Ikageng. Narrative data collection and analysis, as well as a variety of qualitative research methods and media, were used to collect data. These include: focus group discussions, the Mmogo– MethodTM, videos, audio, photographs and observational notes. The thematic analysis of textual data, narrative–oriented inquiry as well as visual data, established trustworthiness of this research through crystallization. By drawing on the deeper symbolic meaning derived through the use of the MmogomethodTM, the study has revealed that the sense of belonging is a relational phenomenon that cannot be understood in absence of the different relational environments. In an African culture the relationship with the current environment resonates with the effects that historical processes, structural abuses, discrimination, racism and devaluation had on individuals whose lives have been uprooted. This study has shown that the older women have a micro–organic relational sense of belonging to the place of relocation and not to the whole context and other relational environments and that they revealed more sense of belonging towards the place where they were relocated from. / Thesis (M.A. (Research Psychology))--North-West University, Potchefstroom Campus, 2012.
