Review: Hybrid Warriors: Proxies, Freelancers and Moscow’s Struggle for Ukraine
No full textAuthor: Anna Arutunyan
Reviewed by Dr. Sarah Lohmann, teaching faculty, University of Washington
Dr. Sarah Lohmann, editor of What Ukraine Taught NATO about Hybrid Warfare (US Army War College Press, 2022), calls Anna Arutunyan\u27s latest book, Hybrid Warriors, a must-read for senior members of the US defense community that encourages strategists to think beyond segmented operations to ensure Russia\u27s broad defeat. Lohmann highlights the book\u27s value in that it provides perspectives that have not yet been heard in the West, as Arutunyan relies on Russian sources from media and academia, as well as hundreds of interviews. Lohmann also notes how Arutunyan challenges what she believes to be the Western narrative around the 2022 Russia-Ukraine War.https://press.armywarcollege.edu/parameters_bookshelf/1042/thumbnail.jp
Dynamics in electron-impact ionization of H(2)O
No full textWe present multiply differential cross sections for electron-impact ionization of the water molecule. The experimental results are compared with theoretical cross sections calculated using a recently developed distorted-wave Born approach for molecules. The experimental cross sections exhibit a very large recoil scattering, which is not predicted by the theory. This has implications for applications of this theoretical approach in areas such as modeling of ionization in biological systems.D. S. Milne-Brownlie, S. J. Cavanagh, Birgit Lohmann, C. Champion, P.

Recent theoretical progress in treating electron impact ionization of molecules
No full text(e,2e) ionization differential cross sections are presented for several molecules. We will compare experimental results with theoretical calculations using the molecular three body distorted wave (M3DW) approximations for H2, N2, H2O and Formic Acid (FA) using better wave-function for the molecules than we had in previous works. Generally, good agreement is found between the M3DW approach and experiments.Ola Al-Hagan, Chuangang Ning, Kate Nixon, Andrew Murray, Christopher Colyer, Mark Stevenson, Birgit Lohmann and Don Madiso
Coplanar symmetric (e,2e) cross sections for krypton 4s ionization
No full textCopyright © Institute of Physics and IOP Publishing Limited 2003The triple-differential cross section for electron impact ionization of the 4s orbital of krypton (binding energy 27.5 eV) has been measured in coplanar symmetric kinematics. The experimental results are presented for outgoing electron energies of 85, 50, 20, 10 and 4 eV. The results are compared with two distorted wave Born approximation calculations; the influence of post-collision interaction (PCI) on the cross sections is investigated by incorporating correct final state boundary conditions in one of the calculations. The influence of PCI is found to be very important at the lower energies. Inclusion of the three-body final state boundary conditions improves the agreement between theory and experiment, but there are still significant discrepancies, indicating that additional physical effects (such as higher-order interactions) are important at lower energies.Matthew A Haynes, Birgit Lohmann, A Prideaux and D H Madiso
Coplanar symmetric (e, 2e) cross sections for argon 3s ionization
No full textCopyright © Institute of Physics and IOP Publishing Limited 2001The triple differential cross section for electron impact ionization of the 3s orbital in argon (binding energy 29.3 eV) has been measured in the coplanar symmetric geometry. The measurements have been performed at incident energies of 129.3, 69.3, 49.3 and 37.3 eV. This corresponds to detecting two equal outgoing electrons with energies of 50, 20, 10 and 4 eV. Comparisons with previous measurements for ionization of the 3p orbital of argon under the same kinematic conditions show significant orbital-dependent effects.Matthew A Haynes and Birgit Lohman
Physics-compatible finite element methods for scalar and tensorial advection problems
No full textChristoph Lohmann introduces a very general framework for the analysis and design of bound-preserving finite element methods. The results of his in-depth theoretical investigations lead to promising new extensions and modifications of existing algebraic flux correction schemes. The main focus is on new limiting techniques designed to control the range of solution values for advected scalar quantities or the eigenvalue range of symmetric tensors. The author performs a detailed case study for the Folgar-Tucker model of fiber orientation dynamics. Using eigenvalue range preserving limiters and admissible closure approximations, he develops a physics-compatible numerical algorithm for this model.

Review: David Lohmann (2003). Das Bielefelder Diakonie-Management-Modell
No full textÜber sechs Kapitel entwickelt David LOHMANN Anregungen und Handreichungen für ein theologisch-ethisches Unternehmensmanagement diakonischer Einrichtungen, ohne dabei ökonomische Sachzwänge außer Acht zu lassen. Durch das qualitative Verfahren des Vergleichs erschließt der Verfasser dokumentarische Quellentexte und generiert daraus eine Theorie für ein theologisch-ethisches Unternehmensmanagement. Zunächst wird eine Theologie der Diakonie nach den Interpretationen von TILLICHs Modell des "gläubigen Realismus", und WICHERNs theologischer Konzeption zur "Inneren Mission" erschlossen. Als das Essenzielle wird eine kybernetische Theorie auf der Basis einer Diakonie-Theologie formuliert. Aus dem Vergleich verschiedener Führungsmodelle favorisiert LOHMANN das St. Galler Management Modell als Ausgangsmodell für das Management diakonischer Unternehmen. Sukzessive werden die theologischen Grundlegungen für die normative, strategische und operative Ebene den betriebswirtschaftlichen Relevanzen angenähert. Durch den Versuch, aus den Werken zweier Theologen des letzten Jahrhunderts und der eigenen Berufspraxis ein zukünftiges Managementmodell zu formulieren, werden aktuelle Bedürfnisse und Erkenntnisse aus der Praxis der Unternehmensleitung diakonischer Einrichtungen nicht berücksichtigt. Eine systematische Methodologie aus der qualitativen Sozialforschung hätte sich angeboten und die Empirie der Arbeit wertvoll unterstrichen. Am Ende der Analyse steht dann ein Managementmodell für diakonische Unternehmen, das die Interdisziplinarität zwischen Theologie und Betriebswirtschaft betont. Der Band bestätigt damit, dass durch ein dem diakonischen Geist angepasstes Management sowohl Theologie als auch Ökonomie zu einer wettbewerbsfähigen Symbiose geführt werden können.In six chapters, David LOHMANN makes suggestions for theological-ethical deaconry management, including a consideration of economic necessities. Through a qualitative comparison of documented sources, the author generates a theory of theological-ethical enterprise management. Following that, the author considers the theology of the deaconry in the context of TILLICH's model of believed realism and WICHERN’s theological concept of the inner mission. At the center of the examination lies a formulation of a cybernetic theory of deaconry theology. Of the available management models, the author favours the St. Galler model as the basic model of deaconry enterprise management. In doing so, the author lays out theological ground rules for the normative, strategic and operational levels of deaconry. In attempting to formulate this prospective deaconry management model through the consideration of the work of the two 20th century theologians and his own personal experience, the current needs and knowledge-base of specific deaconries are not considered. A systematic consideration of quantitative social research would have been a worthwhile supplement. In conclusion, the analysis develops a management model for deaconry enterprises that emphasizes the interdisciplinary aspects of theology and business economics. The book confirms the competitive value of a management model attuned to the theological and economic aspects of a deaconry.En seis capítulos, David LOHMANN hace sugerencias para el manejo teológico-ético, incluyendo una consideración de necesidades económicas. A través de una comparación cualitativa de fuentes documentadas, el autor genera una teoría del manejo teológico-ético de la empresa. Enseguida el autor considera la teología del diaconato en el contexto del modelo del realismo creído de TILLICH y el concepto de misión interna de WICHERN. En el centro del examen permanece la formulación de la teoría cibernética de la teología del diaconato. De los modelos disponibles, el autor favorece el de St. Galler como el modelo básico de manejo de la empresa de diaconato. Al hacerlo así, el autor funda reglas teológicas para los niveles operacionales, estratégicos y normativos del diaconato. Al intentar formular este modelo de manejo prospectivo para el diaconato a través de la consideración del trabajo de dos teólogos del siglo XX y su propia experiencia personal, las necesidades actuales y el conocimiento base de diaconatos específicos no son considerados. Una consideración sistemática de la investigación social cuantitativa habría sido un valioso complemento. En conclusión, el análisis desarrolla un modelo de manejo para la empresa de diaconato que enfatiza los aspectos interdisciplinarios de la teología y la economía de negocio. El libro confirma el valor competitivo de un modelo de administración que armoniza los aspectos teológicos y económicos de un diaconato

We propose that in situations where behavior is somewhat habitual but still flexible, repeated action can be modified by self-talk questions: Instead of a direct cue-behavior association, the situation may lead people to ask themselves a question, which then prompts action. Across three studies, participants showed below-baseline rates of behavior repetition when they were presented with the negative question ""Which one should I not choose?"". In contrast, people tended to repeat their behavior above baseline levels when they were presented with the affirmative question ""Which one should I choose?"". In Experiment 3, this effect vanished when repetition was explicitly requested, providing evidence for our hypothesis that self-talk most effectively guides behavior when behavior is still flexible."Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2018-05-01The student, Sophie Lohmann, accepted the attached license on 2016-04-27 at 18:41.The student, Sophie Lohmann, submitted this Thesis for approval on 2016-04-27 at 19:03.This Thesis was approved for publication on 2016-04-28 at 09:42.DSpace SAF Submission Ingestion Package generated from Vireo submission #9562 on 2016-07-07 at 13:51:0
Gender and European Integration
No full textThe paper assesses the contribution of gender approaches to understanding Europeanintegration. It offers a conceptualization of such approaches as including a distinctontology, epistemology and methodology. While feminist literature on the EuropeanUnion is diverse, all such literature sheds light on the gendered process of Europeanintegration. The authors identify two distinct contributions of this literature: (a) itillustrates the relevance of movement actors and other advocates in shaping EU policies;(b) it shows that economic integration entails the creation of new gender regimes. Thepaper illustrates these contentions presenting case studies of the EU’s response to sextrafficking, the reform of the common agricultural policy, and of enlargement.
