The “Natural” History of Medically Treated Temporal Lobe Epilepsy: What Can an Evidence-Based Approach Tell Us?
Colin Bruce Josephson,Bernhard Pohlmann-Eden
Epilepsy Research and Treatment , 2012, DOI: 10.1155/2012/216510
Abstract: We systematically reviewed the literature to describe the “natural” history of medically treated temporal lobe epilepsy (TLE). No population-based studies recruiting incident cases of TLE irrespective of age exist. Prospective, population-based studies were limited to those recruiting only childhood-onset TLE or those reporting TLE as a subgroup of cohorts of focal epilepsies. Few studies have been performed in the “MRI era” limiting information on natural history secondary to specific pathologies. Available data suggests that TLE is highly variable, with unpredictable transient remissions and low rates of seizure freedom (30 to 50%). Etiology and failure of first and second drug seem to be the most important predictors for treatment prognosis. The role of initial precipitating injuries remains speculative, as imaging information of related events is either missing or conflicting. Prospective cohorts of new-onset TLE with long-term followup using advanced MRI techniques, timely EEG recordings, and assessments of psychiatric comorbidities are needed. 1. Introduction Temporal lobe epilepsy (TLE) is the most frequent medically refractory epilepsy syndrome seen in epilepsy outpatient clinics. It has received considerable attention in recent years owing to the remarkable rates of remission that can be achieved through surgical intervention [1]. Mesial temporal lobe epilepsy (mTLE) associated with hippocampal sclerosis (mTLE-HS), a condition that can be detected by modern magnetic resonance imaging (MRI) techniques with a high sensitivity and specificity, is now the most common indication for epilepsy surgery. To date, therapeutic advances in TLE have far outpaced our understanding of the natural history of the disorder. According to a recent International League Against Epilepsy (ILAE) commission report [2], the natural history of mTLE-HS is characterized by key features such as a history of an initial precipitating injury and a presence of a latent and/or silent period. Prior publications have attempted to assess the course and prognosis of TLE, mTLE, and mTLE-HS using sophisticated electroencephalography (EEG), MRI, and histological techniques trying to identify the “natural” history of all types of TLE. Almost all these studies are limited by the fact that their perspective comes from tertiary care centers and surgical series [3]. The ideal natural history study requires a large prospective cohort of patients with new-onset TLE undergoing extensive structural and functional testing with a followup of >10 years. We conducted a systematic review of the
Vermittlung von Informationskompetenz an Master-Studierende und Doktoranden: Themen und Konzepte
Tobias Pohlmann
Perspektive Bibliothek , 2012, DOI: 10.11588/pb.2012.1.9395
Abstract: Ein Gro teil der existierenden Angebote zur Vermittlung von Informationskompetenz durch Hochschulbibliotheken richtet sich prim r an Studierende in den unteren Semestern. Der vorliegende Artikel betrachtet die Gruppe der fortgeschrittenen Nutzer: Masterstudierende und Promovierende. Aktuelle Angebote für diese Zielgruppen werden beispielhaft dargestellt, gefolgt von m glichen Themen und Konzepten zu ihrer weiteren Unterstützung. Hierbei flie en in der Literatur verfügbare Umfrageergebnisse ein. Für die Gruppe der Doktorandinnen und Doktoranden wurde zudem eine eigene Online-Umfrage durchgeführt. Sie gibt Aufschluss über die Selbsteinsch tzung der Teilnehmer bezüglich ihrer pers nlichen Informationskompetenz, deren Erwerb, relevante Inhalte und geeignete Formen entsprechender Angebote. Die Ergebnisse werden zusammenfassend wiedergegeben und in einem Anhang in Diagrammen ausführlich dargestellt. Erwartungsgem befinden sich konkrete Angebote zur Vermittlung von Informationskompetenz an fortgeschrittene Nutzer noch im Aufbau. Die relevanten Themen hneln grunds tzlich jenen für Studienanf nger, jedoch sind ein ausgepr gter fachlicher Bezug und die Vertiefung von Inhalten bedeutsam. Beide Gruppen ben tigen Angebote zu allgemeinen Recherchestrategien, zur Identifizierung fachspezifischer Angebote sowie zur Nutzung von Datenbanken und Literaturverwaltungssoftware. Für Masterstudierende hat zudem die Internetrecherche sowie die Schaffung eines Bewusstseins für Plagiarismus und richtiges Zitieren Relevanz. Doktorandinnen und Doktoranden zeigen ein gesteigertes Interesse am elektronischen Publizieren, der Ver ffentlichung von Fachartikeln und der Nutzung von E-Publikationen. Für Masterstudierende eigenen sich intracurriculare Schulungsangebote, Angebote im Rahmen von Seminaren und verpflichtende fachspezifische Workshop in Zusammenarbeit mit den Fachbereichen, m glicherweise erg nzt (jedoch nicht ersetzt) durch E-Learning-Angebote. Optionale Workshops sollten m glichst im Wahlpflichtbereich belegt werden k nnen. Für Doktorandinnen und Doktoranden ist eine Integration von Angeboten in die formale Doktorandenausbildung, soweit an der jeweiligen Hochschule praktiziert, sinnvoll. Darüber hinaus ist ihnen selbstbestimmtes Lernen zu erm glichen. Kurse und Workshops sollten m glichst als kompakte eint gige Veranstaltungen konzipiert werden. Auch sonstige Angebote wie Online-Tutorials u. . sollten kompakt und pr zise auf die relevanten Themen eingehen. Nicht zuletzt ist auch die M glichkeit zur Einzelberatung für beide Gruppen wichtig.
Erfüllungsgehilfen? Die Rolle der Bibliotheken im Rahmen der Bücherverbrennungen 1933
Tobias Pohlmann
Perspektive Bibliothek , 2012, DOI: 10.11588/pb.2012.2.9462
Abstract: Dieser Beitrag befasst sich mit den Bücherverbrennungen von 1933 und der Rolle, die Volks- und wissenschaftliche Bibliothekare dabei spielten. Zun chst wird der Verlauf der Bücherverbrennungen dargestellt und hierbei insbesondere auf die Aktion wider den undeutschen Geist“ eingegangen, die ma geblich in der Urheberschaft der Deutschen Studentenschaft“ (DSt) organisiert und durchgeführt wurde. Im Anschluss wird die Bandbreite an bibliothekarischen Verhaltensweisen im Zusammenhang mit den Bücherverbrennungen anhand ausgew hlter Beispiele beleuchtet. Die Betrachtung erfolgt getrennt nach ffentlichen und wissenschaftlichen Bibliotheken, wobei auch die offizielle Haltung der jeweiligen Berufsverb nde VDV und VDB thematisiert wird. Zudem wird auf die so genannten Schwarzen Listen“ eingegangen, die von Volksbibliothekaren erstellt wurden und zahlreiche Titel nunmehr unerwünschter Literatur enthielten. Schlie lich wird neben der Mitwirkung bei der Verbrennung von Büchern auch die Rolle der Bibliothekare im Hinblick auf Bestandsaussonderungen im Falle der Volks- und auf Bestandssekretierungen im Falle der wissenschaftlichen Bibliotheken eingegangen. Der Beitrag zeigt auf, dass das Verhalten der Bibliothekare zwischen Zustimmung und Ablehnung ein breites Spektrum an Ansichten und Verhaltensweisen umfasste. Verallgemeinerte Aussagen sind somit nicht m glich.
Optimal Design of a Multibody Self-Referencing Attenuator  [PDF]
Dongmei Zhou, Jennifer A. Eden
Journal of Power and Energy Engineering (JPEE) , 2015, DOI: 10.4236/jpee.2015.39005
Abstract: The purpose of this paper is to determine the optimal size and number of tubes for a generic attenuator that is similar to Pelamis P2, the wave energy converter. Simulations using ANSYS Workbench, Design Modeler, and AQWA are performed to study the energy absorption at the nodes between the tubes. The analysis is limited to linearized hydrodynamic fluid waves loading on floating bodies by employing three-dimensional radiation/diffraction theory in regular waves in the frequency domain. Three sets of tests are conducted by varying total tube number, each tube length and the order of tubes with different lengths. After a systematic study in the frequency domain, the optimal size and number of the genetic attenuator is recommended.
Intui es sobre o tempo na cria o em artes visuais

Educa??o : Revista do Centro de Educa??o UFSM , 2006,
Abstract: Este artigo aborda quest es ligadas ao processo criador em artes visuais e ao modo como o tempo vivido pode ser percebido durante estes processos. As interroga es que motivaram a pesquisa partiram da constata o do intervalo existente entre o projeto inicial que lan a o movimento de cria o e o trajeto percorrido durante o percurso de realiza o da obra. O texto procura retomar os três deuses da temporalidade: Chronos, Ai n e Kairós, como pontos de cruzamento possíveis de se estabelecer com a experiência do tempo durante o processo de cria o. Chronos, o deus do tempo cronológico n o nos deixa esquecer dos prazos de entrega; Ai n, a eterna presen a (o jogo, a brincadeira) nos faz ter a sensa o de que por alguns momentos, no acontecimento da cria o em artes visuais, é possível paralisar o tempo e viver o “tempo em suspenso”, e Kairós, o deus das encruzilhadas (das bifurca es que se abrem para diferentes futuros) pode fazer surgir uma idéia nova, que, como um raio, nos prenuncia algo inesperado que pode se apresentar através de uma intui o e de nossas próprias escolhas e decis es. Palavras-chave: Tempo. Artes Visuais. Processos de Cria o.
Structural properties of acyclic heaps of pieces with Kazhdan--Lusztig theory
Brent G. Pohlmann
Mathematics , 2008,
Abstract: We introduce the notions of boundary vertex, linear equivalence and effective boundary vertex in the context of Viennot's heaps of pieces. We prove that in the heap of a fully commutative element in a star reducible Coxeter group, every boundary vertex is linearly equivalent to an effective boundary vertex. Using this result, we establish Property W (in the sense of math.QA/0509363) for star reducible Coxeter groups; this corrects a mistake in the latter paper.
Selecting information technology for physicians' practices: a cross-sectional study

BMC Medical Informatics and Decision Making , 2002, DOI: 10.1186/1472-6947-2-4
Abstract: A telephone survey was conducted with office representatives of 407 physician practices in Oregon who had purchased information technology. The respondents, usually office managers, answered scripted questions about their selection process and their perceptions of the software after implementation.Multiple logistic regression revealed that software type, selection steps, and certain factors influencing the purchase were related to whether the respondents felt the software improved the scheduling and financial analysis practice activities. Specifically, practices that selected electronic medical record or practice management software, that made software comparisons, or that considered prior user testimony as important were more likely to have perceived improvements in the scheduling process than were other practices. Practices that considered value important, that did not consider compatibility important, that selected managed care software, that spent less than $10,000, or that provided learning time (most dramatic increase in odds ratio, 8.2) during implementation were more likely to perceive that the software had improved the financial analysis process than were other practices.Perhaps one of the most important predictors of improvement was providing learning time during implementation, particularly when the software involves several practice activities. Despite this importance, less than half of the practices reported performing this step.Health care providers compete for managed care contracts based on cost-effectiveness and quality of care [1-4]. Information technology (IT) provides a cost-effective way to document productivity, performance measures, cost, and quality of care. Since IT has dropped in cost over time, physician practices are now turning to it to meet these needs. Information technology for this study is defined as computer software used to store, transport, or communicate information [2,5-7].The health care organizations that succeed in the 21st

A Program for Baryon Generation and Its Applications to Baryon Fragmentation in DIS
Patrik Eden
Physics , 1996,
Abstract: In an earlier paper, we discuss the ``popcorn'' model for baryon production in quark and gluon jets, and present an improved model (which we call Modified Popcorn Scenarium, MOPS). In this paper we give a manual to the MC program based on MOPS, and also discuss the application of the model to baryon fragmentation, i.e. fragmentation of strings originally contaning a diquark. Model predictions for baryon production in DIS are compared with data.
On Energy Conservation in Lund String Fragmentation
Patrik Eden
Physics , 2000, DOI: 10.1088/1126-6708/2000/05/029
Abstract: I discuss a Monte Carlo algorithm for hadronization in the Lund string fragmentation picture, which conserves energy and momentum exactly as is proposed by the model. An embryo to this Monte Carlo is used to calculate the total decay density of a string. This is found to reach its predicted asymptotic behaviour already at a string energy of about six hadron masses.
