How do humans, their needs, and technology interact in society? Marcel Siegler explores the dialectical relationship between human needs and desires, the demands and requirements of the built world, and the forms of organization that hold both humans and the built world together. He argues that complex societal constellations emerge from the actions individuals perform with the technological means at hand to satisfy their needs and desires in the short and long run. Based on a novel, complementary reading of French philosopher Jean-Paul Sartre, the study develops a conceptual framework for analyzing the intricate machinations of sociotechnical systems from a perspective on situated human-technology interaction.

It has long been recognized that metal spin states play a central role in the reactivity of important biomolecules, in industrial catalysis and in spin crossover compounds. As the fields of inorganic chemistry and catalysis move towards the use of cheap, non-toxic first row transition metals, it is essential to understand the important role of spin states in influencing molecular structure, bonding and reactivity. Spin States in Biochemistry and Inorganic Chemistry provides a complete picture on the importance of spin states for reactivity in biochemistry and inorganic chemistry, presenting both theoretical and experimental perspectives. The successes and pitfalls of theoretical methods such as DFT, ligand-field theory and coupled cluster theory are discussed, and these methods are applied in studies throughout the book. Important spectroscopic techniques to determine spin states in transition metal complexes and proteins are explained, and the use of NMR for the analysis of spin densities is described. Topics covered include: DFT and ab initio wavefunction approaches to spin states Experimental techniques for determining spin states Molecular discovery in spin crossover Multiple spin state scenarios in organometallic reactivity and gas phase reactions Transition-metal complexes involving redox non-innocent ligands Polynuclear iron sulfur clusters Molecular magnetism NMR analysis of spin densities This book is a valuable reference for researchers working in bioinorganic and inorganic chemistry, computational chemistry, organometallic chemistry, catalysis, spin-crossover materials, materials science, biophysics and pharmaceutical chemistry.
Most military historians are in agreement that Feldmarschall Erich von Manstein was the most outstanding German high commander of the Second World War. Many view him as the foremost exponent of large-scale mobile operations in any of the Second World War armies. Surprisingly, no biography of him has yet been written. To this day, his family refuses to release the papers of his estate to the German military archives at Freiburg. Furthermore the contradictions in the personality of von Manstein make it difficult to generate a synthesis. On one side there is an extraordinary military talent, on the other many political and moral aspects. His military achievements stand in sharp contrast to his inhumane policy of occupation in Russia, his active participation in the slaughter of Jews in Southern Ukraine and the Crimea and his ambivalent attitude to the military resistance movement. These contradictions have led the author to describe Manstein as the Janushead - the term chosen for the title of the book. He has not written a traditional biography but a portrait. A complete account of all phases of Mansteins career is given in one chapter, seven more chapters deal extensively with milestones in Mansteins career: his successful plan for the battle of France which led to the defeat of the French Army in less than one month, his dereliction of duty during the battle for Stalingrad, his hubris which led to the disaster of the battle for Kursk, his refusal to take part in the military resistance movement, his compliance with the Commissar order and his involvement in the Holocaust. he author has widened the subject well beyond the personality of its central figure. It shows how the Nazi system, step by step, succeeded in perverting the centuries-old traditions of the Prussian and German officer corps.

Version control is a widely used practice among software developers. It reduces the risk of changing their software and allows them to manage different configurations and to collaborate with others more efficiently. This is amplified by code sharing platforms such as GitHub or Bitbucket. Most version control systems track files (e.g., Git, Mercurial, and Subversion do), but some programming environments do not operate on files, but on objects instead (many Smalltalk implementations do). Users of such environments want to use version control for their objects anyway. Specialized version control systems, such as the ones available for Smalltalk systems (e.g., ENVY/Developer and Monticello), focus on a small subset of objects that can be versioned. Most of these systems concentrate on the tracking of methods, classes, and configurations of these. Other user-defined and user-built objects are either not eligible for version control at all, tracking them involves complicated workarounds, or a fixed, domain-unspecific serialization format is used that does not equally suit all kinds of objects. Moreover, these version control systems that are specific to a programming environment require their own code sharing platforms;popular, well-established platforms for file-based version control systems cannot be used or adapter solutions need to be implemented and maintained. To improve the situation for version control of arbitrary objects, a framework for tracking, converting, and storing of objects is presented in this report. It allows editions of objects to be stored in an exchangeable, existing backend version control system. The platforms of the backend version control system can thus be reused. Users and objects have control over how objects are captured for the purpose of version control. Domain-specific requirements can be implemented. The storage format (i.e. the file format, when file-based backend version control systems are used) can also vary from one object to another. Different editions of objects can be compared and sets of changes can be applied to graphs of objects. A generic way for capturing and restoring that supports most kinds of objects is described. It models each object as a collection of slots. Thus, users can begin to track their objects without first having to implement version control supplements for their own kinds of objects. The proposed architecture is evaluated using a prototype implementation that can be used to track objects in Squeak/Smalltalk with Git. The prototype improves the suboptimal standing of user objects with respect to version control described above and also simplifies some version control tasks for classes and methods as well. It also raises new problems, which are discussed in this report as well.
This book presents the latest developments in the field of forensic pathology/forensic medicine, including important advances in forensic histopathology, forensic radiology, medical malpractice, understanding of child abuse, and forensic toxicology. Various forms of trauma are addressed in individual chapters, and among the other topics covered are traffic medicine, forensic alcohol toxicology, forensic DNA analysis, forensic osteology, and international regulations. The book includes a wealth of color illustrations and numerous tables presenting key facts. The authors are leading experts in general pathology, forensic radiology, and forensic toxicology. Forensic Pathology/Forensic Medicine: Fundamentals and Perspectives will be of interest not only to specialist pathologists and those working in forensic medicine, but also to coroners, forensic physicians, students, lawyers, attorneys, and policemen.
