No full texteconomic&political bookfair2015Includes bibliographical references and index.xii, 300 pages :"With a new author team contributing decades of practical experience, this fully updated and thoroughly classroom-tested second edition textbook prepares students and practitioners to create effective forecasting models and master the techniques of time series analysis. Taking a practical and example-driven approach, this textbook summarises the most critical decisions, techniques and steps involved in creating forecasting models for business and economics. Students are led through the process with an entirely new set of carefully developed theoretical and practical exercises. Chapters examine the key features of economic time series, univariate time series analysis, trends, seasonality, aberrant observations, conditional heteroskedasticity and ARCH models, non-linearity and multivariate time series, making this a complete practical guide. A companion website with downloadable datasets, exercises and lecture slides rounds out the full learning package"-- Provided by publisher."The econometric analysis of economic and business time series is a major field of research and application. The last few decades have witnessed an increasing interest in both theoretical and empirical developments in constructing time series models and in their important application in forecasting. This book aims at reviewing several important developments within the context of forecasting business and economic time series"-- Provided by publisher
Mobile Africa: an introduction
No full text
The case studies in this book on mobility in sub-Saharan Africa critically discuss dichotomous interpretations of mobility and reject the idea that migration indicates a breakdown in society. They adopt the approach that sedentary and mobile worlds converge and that mobility is part of the livelihood system of African people.

Projections of Pain: Neonatal pain, what remains in the brain after the wheels of time
No full text__Abstract__
The International Association for the Study of Pain (IASP) has defined ’pain’ as ‘An unpleasant
sensory and emotional experience associated with actual or potential tissue damage,
or described in terms of such damage’ with the note that ‘Pain is always subjective. Each
individual learns the application of the word through experiences related to injury in early
life’. Unfortunately some individuals experience pain from injuries in very early life, such
as preterm born children, who will need to undergo painful procedures, and children who
require major surgery shortly after birth. These children will therefore receive painkillers
or anaesthetics in a life stage in which the brain is rapidly developing. There is ongoing
concern about the potential negative effects of both early exposure to pain, analgesia
with opioids and exposure to anaesthetics in infancy

Markets of well-being: navigating health and healing in Africa
No full text
Health and healing in Africa have increasingly become subject to monetization and commodification, in short, the market. Based on fieldwork in nine countries, this volume offers different perspectives on these emerging markets and the way medical staff, patients, households and institutions navigate them in their quest for well-being. Contributions: Introduction: Economic ethnographies of the marketization of health and healing in Africa (Rijk van Dijk and Marleen Dekker); Milking the sick: medical pluralism and the commoditization of healthcare in contemporary Nigeria (Akinyinka Akinyoade and Bukola Adeyemi Oyeniyi); Organizing monies: the reality and creativity of nursing on a hospital ward in Ghana (Christine Böhmig); Market forces threatening school feeding: the case for school farming in Nakuru town, Kenya (Dick Foeken et al.); Dashed hopes and missed opportunities: malaria control policies in Kenya (1896-2009) (Kenneth Ombongi and Marcel Rutten); The market for healing and the elasticity of belief: medical pluralism in Mpumalanga, South Africa (Robert Thornton); Medical knowledge and healing practices among the Kapsiki/Higi of northern Cameroon and northeastern Nigeria (Walter E.A. van Beek); The commodification of misery: markets for healing, markets for sickness (Zanzibar) (Nadine Beckmann); Individual or shared responsibility: the financing of medical treatment in rural Ethiopian households (Marleen Dekker); Can't buy me health: financial constraints and health-seeking behaviour in rural households in central Togo (Andr‚ Leliveld et al.); Marriage, commodification and the romantic ethic in Botswana (Rijk van Dijk).

Control algorithm for dynamic solar shadings: A simulation study for office buildings based on ISO 52016-3
No full textIn 2019, the building sector was accountable for emitting 12GtCO2, equivalent to 21 % of global GHG emissions. To achieve carbon neutrality by 2050, the building sector must change its pace. One of the ways to achieve this goal is through the installation of dynamic solar shadings in buildings. This study focuses on a single office in two locations characterised by a temperate climate: Liège (Belgium) and Milan (Italy). Two control strategies are designed for Venetian and Roller blinds, one with and one without glare evaluation. They both integrate horizontal illuminance, room occupancy, indoor operative temperature and vertical irradiance according to a multi-criteria approach based on ISO 52016-3. The control strategy aims to balance visual comfort, heating, artificial lighting and cooling energy needs and considers user satisfaction by evaluating the shading activation time. The control algorithms are applied and validated on a DesignBuilder shoebox model. Regardless of location, the control strategy that includes glare control improves the user's visual comfort in terms of light quantity and discomfort glare. However, a total annual energy needs increase is registered independently of the shading. Conversely, if glare is not included in the control strategy, control of thermal loads is observed. This work contributed to developing ISO 52016-3 shading control scenarios for offices and is intended for shading producers, solar shading associations, façade engineers, facility managers and the scientific community working on solar shading simulation and analysis
Ergonomic Exoskeleton Synthesis: Application to a Wearable Passive Exoskeleton for the Shoulder
No full textThe human machine-interface is more important than ever in the field of exoskeletons. Current design approaches lack a way of systematically designing the ergonomics of exoskeletons. Methods with a more pro active approach to ergonomics have to be developed. This thesis extends existing methods by which self aligning mechanisms are created with a systematic approach. A synthesis method is proposed by which all possibilities are synthesized. These possibilities are then excluded based on kinematic requirements on the system. The remaining possibilities are optimized based on ergonomic guidelines to obtain a set of solutions from which the designer can make well founded design choices. A force-deflection analysis was performed on the resulting solutions. This proposed method is applied to a planar passive exoskeleton for the shoulder. The method was successfully applied by using the total link length, reachable workspace, distance to the body and singularity avoidance as objectives for the optimization. Stiffness was added to the joints to obtain the required force-deflection behavior. The resulting objective values were verified by means of a prototype. The test results showed to be within reasonable bounds to verify the method for the planar case. The force-deflection analysis showed results that can be achieved by linear springs. This has to be verified by additional tests. The proposed method can be used as a tool in future exoskeleton design and can be extended with additional objective functions and constraints and can be extended to the three dimensional case
