A comparative, whole-of-society approach to the Boko Haram insurgency that offers a more nuanced understanding of the risks, resilience and resolution of violent radicalization in Nigeria and beyond. It is now more than a decade since the violent Islamic group Boko Haram launched its reign of terror across northern Nigeria, claiming more than 27,000 lives and displacing over 2 million people. While its territorial gains have largely been recaptured, the insurgency rages on, devastating communities across vast stretches of the north-east and disrupting governance, livelihoods and food security, as well as posing a security risk to Niger, Chad and Cameroon. Less attention is paid to the pervasive popular rejection of violent extremism on the ground. How did a diverse and economically dynamic West African society unravel so violently, and for so long? Why does radicalizationhave so little influence on large Muslim populations in surrounding areas, such as the Yoruba in south-western Nigeria, or the poor ethnically similar Muslim majority in central Niger just north of the border? This book looks beyond the details of the insurgency to examine the wider social and political processes that explain why Boko Haram emerged when and where it did, and what forces exist within society to contain it. Drawing on the detailed fieldworkof specialist Nigerian and Nigerianist scholars from Nigeria, connecting the worst of Boko Haram violence to the wider realities of the present, the book offers new insights into the drivers of Islamic extremism in Nigeria - poverty, regional inequality, environmental stress, migration, youth unemployment, and state corruption and human rights abuses - with a view to charting more sustainable paths out of the conflict.

Companies do not live on what they manufacture, but on what they sell. Thus, sales is the central department in any company. Are there any basic methods that salespeople should consider and can these be learnt? How do manipulation and rhetoric play a role? Can our knowledge from modern psychology be integrated in the sales process and do they have a positive effect on the salesperson's behaviour? Here, Wolf Ehrhardt and Hubert Buschmann combine the success factors in selling with knowledge gained from psychoanalysis and apply these step-by-step to the phases of the sales talk. The book is aimed at the successful top salesperson, who enhances the company's value over the long term.

Analyses the complexities of Christian-Muslim conflict that threatens the fragile democracy of Nigeria, and the implications for global peace and security. In northern Nigeria, high levels of ethnic diversity have coincided with acute polarization between Muslims and Christians, increasingly fuelling violent conflict. The climate of insecurity threatens northern Nigeria's development, accentuates the inequalities between it and the rest of the country, and undermines the attempt to stabilize democracy in the country. Externally, fears have also been expressed that Islamist movements in northern Nigeria form part of a wider network constituting a threat to global peace and security. Refuting a "clash of civilizations" between Muslims and Christians, the authors of this new study highlight the multiplicity of Muslim and Christian groups contending for influence and relevance, and the doctrinal, political and historical drivers of conflict and violence between and within them. They analyse three of the most contentious issues: the conflicts in Jos; the Boko Haram insurgency; and the challenges of legal pluralism posed by the declaration of full Sharia law in 12 Muslim majority states. Finally, they suggest appropriate and effective policy responses at local, national and international levels, discussing the importance of informal institutions as avenues for peace-building and the complementarities between local and national dynamics in the search for peace. Abdul Raufu Mustapha is Associate Professor in African Politics, University of Oxford. David Ehrhardt is Assistant Professor of International Development at Leiden University College.

This book discusses the state-of-the-art and open problems in computational finance. It presents a collection of research outcomes and reviews of the work from the STRIKE project, an FP7 Marie Curie Initial Training Network (ITN) project in which academic partners trained early-stage researchers in close cooperation with a broader range of associated partners, including from the private sector. The aim of the project was to arrive at a deeper understanding of complex (mostly nonlinear) financial models and to develop effective and robust numerical schemes for solving linear and nonlinear problems arising from the mathematical theory of pricing financial derivatives and related financial products. This was accomplished by means of financial modelling, mathematical analysis and numerical simulations, optimal control techniques and validation of models. In recent years the computational complexity of mathematical models employed in financial mathematics has witnessed tremendous growth. Advanced numerical techniques are now essential to the majority of present-day applications in the financial industry. Special attention is devoted to a uniform methodology for both testing the latest achievements and simultaneously educating young PhD students. Most of the mathematical codes are linked into a novel computational finance toolbox, which is provided in MATLAB and PYTHON with an open access license. The book offers a valuable guide for researchers in computational finance and related areas, e.g. energy markets, with an interest in industrial mathematics.

R2,566 Discovery Miles 25 660 Ships in 10 - 15 working days

This book addresses several mathematical models from the most relevant class of kp-Schrödinger systems. Both mathematical models and state-of-the-art numerical methods for adequately solving the arising systems of differential equations are presented. The operational principle of modern semiconductor nano structures, such as quantum wells, quantum wires or quantum dots, relies on quantum mechanical effects. The goal of numerical simulations using quantum mechanical models in the development of semiconductor nano structures is threefold: First they are needed for a deeper understanding of experimental data and of the operational principle. Secondly, they allow us to predict and optimize in advance the qualitative and quantitative properties of new devices in order to minimize the number of prototypes needed. Semiconductor nano structures are embedded as an active region in semiconductor devices. Thirdly and finally, the results of quantum mechanical simulations of semiconductor nano structures can be used with upscaling methods to deliver parameters needed in semi-classical models for semiconductor devices, such as quantum well lasers. This book covers in detail all these three aspects using a variety of illustrative examples. Readers will gain detailed insights into the status of the multiband effective mass method for semiconductor nano structures. Both users of the kp method as well as advanced researchers who want to advance the kp method further will find helpful information on how to best work with this method and use it as a tool for characterizing the physical properties of semiconductor nano structures. The book is primarily intended for graduate and Ph.D. students in applied mathematics, mathematical physics and theoretical physics, as well as all those working in quantum mechanical research or the semiconductor / opto-electronic industry who are interested in new mathematical aspects.

R4,485 Discovery Miles 44 850 Ships in 10 - 15 working days

Combining the disciplines of biological, physical and chemical science, microbial forensics has a rapidly rising profile in a world increasingly troubled by the threat of 'biocrime' and 'bioterrorism'. This valuable resource is a major addition to a body of literature reckoned to lack sufficient breadth. It presents a variety of phenotypic and trace signature methodologies associated with cultured microorganisms that, despite being genetically identical, may be characterized by differing cultural environments. One of the central challenges faced by those working in this field is the sheer diversity of potentially harmful agents, which in themselves total more than 1000 viruses, bacteria, fungi and protozoan parasites. Their numerous additional variants render the process of 'fingerprinting' biological agents notoriously difficult, especially when the limitations of genetic analysis are factored in. Attribution of crime is relatively easy through human DNA, but lacking the genetic individuation of humans and animals, microbial forensics has to complement phylogenetic techniques with chemical and physical ones. In the best case, genetic analysis in the 'biocrime' sector can exclude sources, narrow the population of possible sources and support associations with potential sources. To complement these genetic techniques, chemical and physical methods can be used to compare 'signatures' imparted to microbial samples by environments in which they are grown and processed. Collating a range of microbiological fingerprinting techniques in one volume, and covering everything from statistical analysis to laboratory protocols, this publication furthers the aim of forensic investigators who need robust and legally admissible forensic evidence to present in a courtroom.

This is a well thought-out, highly practical text covering contemporary 'in vitro' techniques for drug absorption studies. Starting at the molecular level of investigation, it continues with cell monolayer models (both primary and cell lines) and culminates with in situ techniques as a final testing format. In addition, chapters on high-throughput assays, in vitro-in vivo correlation, bioinformatics and regulatory issues are covered, giving a comprehensive overview of available models and techniques. Moreover, an appendix consisting of a number of practical protocols is available online, updated as needed, and should prove very helpful to apply the techniques directly to the benchside.

Jan Ehrhardt, Cristian Lorenz
R5,556 Discovery Miles 55 560 Ships in 10 - 15 working days

Respiratory motion causes an important uncertainty in radiotherapy planning of the thorax and upper abdomen. The main objective of radiation therapy is to eradicate or shrink tumor cells without damaging the surrounding tissue by delivering a high radiation dose to the tumor region and a dose as low as possible to healthy organ tissues. Meeting this demand remains a challenge especially in case of lung tumors due to breathing-induced tumor and organ motion where motion amplitudes can measure up to several centimeters. Therefore, modeling of respiratory motion has become increasingly important in radiation therapy. With 4D imaging techniques spatiotemporal image sequences can be acquired to investigate dynamic processes in the patient's body. Furthermore, image registration enables the estimation of the breathing-induced motion and the description of the temporal change in position and shape of the structures of interest by establishing the correspondence between images acquired at different phases of the breathing cycle. In radiation therapy these motion estimations are used to define accurate treatment margins, e.g. to calculate dose distributions and to develop prediction models for gated or robotic radiotherapy. In this book, the increasing role of image registration and motion estimation algorithms for the interpretation of complex 4D medical image sequences is illustrated. Different 4D CT image acquisition techniques and conceptually different motion estimation algorithms are presented. The clinical relevance is demonstrated by means of example applications which are related to the radiation therapy of thoracic and abdominal tumors. The state of the art and perspectives are shown by an insight into the current field of research. The book is addressed to biomedical engineers, medical physicists, researchers and physicians working in the fields of medical image analysis, radiology and radiation therapy.

R2,951 Discovery Miles 29 510 Ships in 10 - 15 working days

This volume contains the invited papers and selected contributed papers presented at the biennial International Symposium on ELECTRON COLLISIONS WITH MOLECULES, CLUSTERS AND SURF ACES held at Royal Holloway, University of London from 29th to 30th July, 1993. This Symposium was a Satellite Meeting of the XVIII International Conference on the Physics of Electronic and Atomic Collisions (ICPEAC) and follows a 16 year tradition of Satellite Conferences in related areas of collisions held in association with previous ICPEAC's. In the past each of these electron -molecule symposia covered the broad field of electron-molecule scattering at rather low energies, but also included hot topics. This time as well as covering the whole field, well defined electron collisions with clusters and with particles in the complex potential of a surface were emphasized. Not many details are known about such collisions, although they become more and more important in surface characterisation, plasma-wall interactions, electron induced desorption and reorganisation of adsorbed particles. Recently, much work, theoretical and experimental, has been devoted to electron collisions with rather large carbon, silicon and halogen containing molecules. These problems are of relevance in plasma assisted thin film formation and etching of surfaces and can now be approached with advanced theoretical methods and experimental equipment.

An (e,2e) experiment is the measurement of an electron impact ionization process where both the exiting electrons are detected in coincidence. Such measurements are almost at the limit of what can be known, in quantum mechanical terms, and its description presents a substantial theoretical challenge. There are at least two very good reasons for studying (e,2e) and related processes. In the first place we are now only beginning to understand the dynamics of the collision process. The range and sophistication of present experiments allow us to identify kinematic regimes where delicate and subtle effects can be observed, stretching current theories to their limit. Secondly, the multiple coincident technique offers us the possibility of an analytical tool that could be used to probe the structure of the target, be it atom, molecule, thin film or surface. Measurements are now being performed at threshold on H, on the inner shell levels of Au and Ag using projectiles at relativistic energies, with spin-polarized electrons on Li, on a myriad of molecules in symmetric, noncoplanar kinematics, and on He in a multitude of different geometries. The technique has recently been extended to excitation ionization (e,3e) and (gamma,2e) experiments. Major theoretical advances have also been made, but much still remains to be done. This volume contains the invited papers that were presented at the Workshop on (e,2e) and related processes which took place in September/October 1992 in Cambridge, UK. The three major review papers which it contains together form an excellent introduction to this new and rapidly expanding area of physics and set the scene for the wide range of research contributions, both experimental and theoretical, from the leading scientists in the field.
