Navigations of a globalizing Chad: Nomadic Walad Djifir grounded in connectivity
A focus on the everyday has produced this ethnography, which hopes to give a nuanced voice to an extended family of semi-sedentary nomads, living at the centre of a country and region known for its political turmoil, ecological insecurities, and socio-economic hardship. Based in central Chad, the Walad Djifir are part of extensive socio-economic networks, ranging from very local cattle markets, to Western Unions in Libya, and selling merchandise in the Central African Republic. The ferīkh (nomadic camp) is where all of the Walad Djifir’s networks meet, and often also begin— providing the departure point of this research. This analytical and methodological approach embraces the intricate relationships between sedentary and mobility, the mundane and the extreme, flexibility and expectations to explore how regional trends can be understood in light of the Walad Djifir’s daily lives. Over time, the Walad Djifir have developed ways of coping and dealing with insecurities, interacting with infrastructural, technological, and socio-political developments in specific ways. In exploring how such insecurities and crises become anchored into the everyday, the ferīkh provides answers. It is precisely the mundane elements of daily life which anchor disruption.History and International Relation
Polymorphic transitions in cocoa butter studied by time resolved small-angle and wide-angle x-ray scattering using synchrotron radiation
X-ray diffraction is a non-destructive technique which may be used to reveal information about the structure of materials, and is already a widely used tool in the study and determination of the polymorphic nature of cocoa butter and associated triacylglycerols which comprise cocoa butter. Simultaneous wide-angle x-ray scattering (WAXS) and small-angle scattering (SAXS) using synchrotron sources has been carried out on cocoa butter and cocoa butter containing selected additives. Conventional WAXS in a SAXS/\VAXS set up gives information on the cocoa butter atomic distances in the range of 3 - 8 angstroms (A), i.c. packing of cocoa butter chains, and is a familial' and powerful technique in enabling the identification of the polymorphic form of cocoa butter. Whereas SAXS provides information on length scales of 50 - 500 A, i.e. the layout of whole molecules in the form of layers. By using synchrotron sources and the associated high brilliance x-rays, it is possible to study the crystallisation in real-time. Whereas WAXS patterns can take a long time to develop, the associated SAXS patterns evolve before any peaks are observed in the WAXS and are concerned with the onset of crystallisation as well as changes in the pre-crystalline structure and pre-cursors prior to the onset of crystallisation which can determine the final characteristics and properties of the product. Similarly, during melting, the SAXS is the last to survive, in some cases long after the WAXS patterns have disappeared. By recording the SAXS patterns in real-time and using a suitably fast time resolution it is possible to observe the formation of the different polymorphic forms of cocoa butter. As well as transitions between polymorphs via intermediate phases which were observed, including the transition from form I to form III via an intermediate phase, and the formation of form V from the melt phase via an intermediate phase. SAXS studies also provided the ability to study cocoa butter systems containing additives such as sucrose, which itself produces a very strong pattern, making it impossible to identify cocoa butter using the conventional WAXS. It was observed that the addition of sucrose to cocoa butter at the onset resulted in a faster crystallisation rate and a shorter induction time. Other additives were used including silica particles of size 7 and 14 nm which provided a large surface area and also resulted in an increased crystallisation rate and a shorter induction time, seen to depend on surface area. The effect of stearic acid, which is one of the fatty acids present in the many triacylglyccrols of cocoa butter, was also observed in the following two situations: i) stearic acid present and already largely crystallised ii) stearic acid itself crystallising rapidly. It was found that cocoa butter crystallised at higher temperatures with stearic acid present, which promoted nucleation in particular

Uncovering the secrets of a productive environment, A journey through the impact of plants and colour
This PhD concerns the relationship between the physical environment and knowledge productivity. To create an optimal environment it is important to study the needs of knowledge workers in connection to the characteristics of the physical environment. Two components of the physical environment have been analysed: plants and colour. The effects of plants on productivity are studied by a critical assessment of the literature. The impact of colour has been studied by an extensive review of the literature and a comparison of human responses to a red and blue painted meeting room, in a real life setting. In addition, questionnaires have been disseminated to measure peoples’ colour preferences on different topics. The choice for plants and colour is based on personal interest and because it is relatively easy to add and change plants and colours in real life settings. In the reviews of the literature particular attention has been paid to the research methods applied by other researchers, in particular in the field of environmental psychology, in order to understand the mechanisms behind the interaction between people and their environment and how this interaction affects their productivity. Based on these insights, a new framework has been developed to measure the perception of the built environment. Chapter 2 discusses the relationship between productivity of the knowledge worker, his networks, and knowledge, in connection to the physical environment. To ensure that the knowledge worker will be both productive and happy, it is hypothesized that it is important that he can fulfil all his needs. The psychologists Ryan and Deci (2000, 2001) mention three psychological needs: competences, relatedness and autonomy. Pink (2010) added two other needs: purpose and mastery. In knowledge work a distinction can be made between four types of work moods that not only matches with insights of modern Western psychologists, but also with ancient Eastern wisdom: social observation, collectiveness, contemplation and awareness. It is concluded that four characteristics of the physical environment can contribute to knowledge productivity: structure, variety, psychological safety and identity. These four factors have been elaborated into practical guidelines how to support the energy and different moods of the knowledge worker. Chapter 3 presents a critical assessment on the effects of plants on productivity, based on an review of the literature. Next to effects on indoor air quality and relative air humidity, plants have in general a positive effect on productivity. The reactions of people can be physical/physiological, affective, or cognitive. Due to the huge variety in research methods and research settings, the research findings are not well comparable. For this reason, an overview of test aspects and a list of plant characteristics is presented that should be taken into account in conducting new research. In this thesis will be focused on the totality of the environment. After a review on a component that easily can be isolated, the next component is integrated in context and can only be approached in totality. Chapter 4 presents the real life test whether different coloured meeting rooms (red, blue and a reference room) had any effect on self-reported productivity. No significant effects were found in the responses to the questionnaires. It is assumed that the participants were fully occupied by the meetings so that they didn’t experience consciously the surrounding colours. A relatively large number of subjects responded that colour did not matter related to productivity (65%), collaboration (58 %) and wellbeing (33 %). Chapter 5 provides an overview of colour preferences of 1077 Dutch people who were asked to fill out a questionnaire. Gender, age and education and some personality characteristics were significantly related to colour preferences. The overall favourite colour was blue although differences exist between males and females: especially males prefer blue. The overall colour preference for clothing is black: females preferred this colour a bit more than males. The most preferred colour for the interior of buildings is white. Regarding states of mind most people prefer white to be quiet or being able to concentrate, and red to be energetic. Regarding being creative, they stated to have no colour preference. Remarkably most people choose for the physical environment the colour white (30 till 40%) and a substantial percentage (16 till 22%) stated to have no colour preference. Based on this analysis of colour preferences, people seem to be less interested in the application of particular colours in their environment. Chapter 6 presents an in-depth analysis of the experience of colour in order to shed more light on how colour affects people physiologically, affectively and cognitively. This analysis is based on theoretical knowledge found in the literature. This literature shows that scientists, philosophers, artists and architects are rather sceptical about the often rational and scientific approach to understand colour. Theoretically, twelve colour characteristics can be discerned how colour appears in nature which can be linked to the twelve senses that were mentioned by Rudolf Steiner and to twelve colour contrasts. Both in practice and science, the HSI values (hue, saturation and intensity) are used to define colour, which is limited to only three colour contrasts. It is concluded that in order to understand the experience of colour in its totality, all twelve colour contrasts should be taken into account that can be related to the twelve senses. Chapter 7 discusses possible pitfalls in conducting colour research by using questionnaires. By means of accurate observations during the colour test of Chapter 4 it turned out that the responses to the questionnaires could not always clearly be related to the research topics and did not always reflect the actual views of the subjects. For this reason additional personal interviews have been conducted with a number of subjects after the test. Contextual, personal and psychological factors showed to influence the responses of the subjects, including well-known phenomena such as the impact of personal interest, social desirability and cognitive dissonance reduction. Chapter 8 reflects on the often applied three dimensions arousal, pleasure and dominance, that were developed by Mehrabian and Russell (1974) to measure people’s environmental experiences and are still widely used in environmental psychology research. The many studies on people-environment interactions are hard to compare due to the different interpretations of these dimensions and the use of a huge variety of related adjectives. In this PhD research an attempt has been made to explore the connections between pleasure, arousal and dominance, the ABC model of attitude with the factors Affect, Behaviour and Cognition, and the three functions of the soul, feeling, acting and thinking, that were mentioned by Plato. It can be concluded that the dimensions of arousal, pleasure and dominance as Mehrabian and Russell originally have meant to be, are still appropriate to be used to describe peoples’ experience of the physical environment, provided that the dimensions are well defined and operationalised in valid adjectives. In particular the often neglected third dimension ‘dominance’ deserves a rehabilitation. Based on the discrepancies and the flaws that were found in research using pleasure, arousal and dominance to measure the experience and perceptual qualities of the built environment, chapter 9 presents a new framework with bipolar adjectives to describe the experience of the physical environment. This framework refers to the twelve senses that were mentioned by Rudolf Steiner. By linking sensory information of the twelve senses to specific parts of the environment, it is possible to define people’s experience of the physical environment in a more clear and objective way. The framework has been tested with practitioners from the field of housing and care and with designers. It showed to be applicable to get a sound understanding of the qualities of the physical environment, why people respond differently to the same environment, and how to improve this environment. Further testing of the framework with different samples and in different settings is needed to validate the framework. The thesis ends with chapter 10 that presents the overall conclusions and recommendations and reflects on the limitations of the research and next steps. This study tried to disentangle the complex concept productivity into four different work moods (contemplation, social observation, collectiveness, and awareness) and mentions four important elements of the physical environment: structure, variety, psychological safety and identity. The review on the effects of plants on productivity showed that plants in general have positive effects. Based on the research on colour, this relationship could not clearly be defined due to the complexity of both the concepts colour and productivity. However, the effects of colour on mood are definable. Because productivity can be conceived as a phenomenon existing of four types of work moods, future researchers can approach productivity more concrete. The developed framework to value and assess the totality of the environment can be helpful.Industrial DesignIndustrial Design Engineerin
