Towards Answering, What Do We Know about Elementary Pre-Service Teachers’ Noticing Skills in Science? A Pre-Requisite to Prepare Them to Teach Responsively in Science Classrooms  [PDF]
Tejaswini Dalvi, Anna Hofmann
Creative Education (CE) , 2019, DOI: 10.4236/ce.2019.102027
Abstract: A teachers’ ability to notice and analyse the substance of student thinking, is an important feature of effective science teaching. To prepare new science teachers to attend to students’ thinking, it is important for teacher educators to first understand what novice teachers notice in science classrooms, what they associate with the idea of noticing and in what ways their noticing skills can progress. To study novice teachers’ noticing abilities, our study employs two different assessment tools, an open noticing assignment and a focused noticing task as pre and post assessments during a semester long science methods course. We report on a variety of noticing themes that highlight a wide variation in what the novice teachers perceive as important to notice in science classrooms. Pre-post analysis of these noticing themes suggests a shift in noticing from general classroom aspects towards noticing science specific aspects as science topics or concepts being discussed and students’ ideas about those. Using a mixed methods analysis lens for both tools, we present various sophistication levels of teacher noticing. These levels not just serve as an indicator of the PSTs’ noticing skills but also as a framework for educators to help PSTs develop responsive teaching strategies in elementary science classrooms.
Neurocode-Tracking Based on Quantitative Fast Dynamic EEG Recording in Combination with Eye-Tracking  [PDF]
Wilfried Dimpfel, Hans Carlos Hofmann
World Journal of Neuroscience (WJNS) , 2014, DOI: 10.4236/wjns.2014.42013
Abstract:

Information processing within the brain relies on electro-chemical features. Electric events are accessible by recording of the EEG. These electric oscillations might be regarded as a neuronal code carrying information on important motor, cognitive and emotional events. A new approach of quantitative assessment of very short time epochs of 364 ms has been developed on the base of particularly defined frequency ranges and called “Neurocode-Tracking”. The new method was technically validated by the use of a signal generator and was found to correspond to classical quantitative EEG analysis except for some smudging during the transition from one frequency range to the next. Real data from a subject were obtained during relaxation and performance of three mental tasks. Data were time averaged for 180 s using the classical method and compared to data averaging during 16.4 s. Results were nearly identical with respect to spectral signatures showing the expected midline frontal theta increases during performance of three cognitive tests but not during relaxation. Collection of very short time epochs of 728 ms duration confirmed task dependent frontal theta increases, most prominent during calculation performance test (CPT), less during d2-concentration and memory test, none during relaxation. Finally, the new technique was combined with eye-tracking. Capture of the EEG mapping video of Neurocode-Tracking and synchronization with the gaze overlay video by starting recording with an audio signal (gong) allowed a match of gazes precisely with the corresponding electric events. Use of this technical combination in research will hopefully lead to a new understanding of spectral signatures of electric activity called enkephaloglyphs.

Supply Chain Differentiation: Background, Concept and Examples  [PDF]
Erik Hofmann, Stephan Knébel
Journal of Service Science and Management (JSSM) , 2016, DOI: 10.4236/jssm.2016.92020
Abstract: The purpose of this paper is to provide new evidence in the field of supply chain differentiation. It aims to combine insights of supply chain management with the service dominant logic to connect fundamental customer requirements with supply chain decision-making. The paper claims to provide a framework that brings together the most relevant factors in the context of supply chain differentiation. The contents of the framework were applied as source to develop a generic decision support flowchart for supply chain executives. From the perspective of “test consumers”—supplemented with secondary data—two cases were examined. The cases provide insights for supply chain differentiation approaches of Adidas and Lego®. The crucial factor to link customer requirements with supply chain settings turned out to be the magnitude of customer co-creation along the value chain under consideration of synergies across the channels. The framework provides the opportunity to structure the complex multi-criteria decision problem constituted by supply chain differentiation. The paper provides helpful insights that could be used as starting point for the development of several industry specific decision-finding models or applications in supply chain differentiation.
Study of superheavy elements
Hofmann,Sigurd;
Nucleus , 2007,
Abstract: abstract the nuclear shell model predicts that the next doubly magic shell-closure beyond 208pb is at a proton number z = 114, 120, or 126 and at a neutron number n = 172 or 184. the outstanding aim of experimental investigations is the exploration of this region of spherical ‘superheavy elements’ (shes). experimental methods are described, which allowed for the identification of elements produced on a cross-section level of about 1 pb. the decay data reveal that for the heaviest elements, the dominant decay mode is alpha emission, not fission. decay properties as well as reaction cross-sections are compared with results of theoretical investigations.
Developments in Blended Learning
Andreas Hofmann
Economics and Organization of Future Enterprise , 2008, DOI: 10.2478/v10061-008-0007-9
Abstract: The purpose of this paper is to provide a concise introduction to blended learning. In this paper, the author gives a brief summary of the historical movements in the field of academic and organizational learning that finally led to the development of blended learning, and provides several definitions of term blended learning, which is not yet clearly defined by academic writing. Finally, the paper introduces a blended learning model outlined by Baldwin-Evans (2006) which is augmented with collaborative components as found in communities of practice to enhance informal learning and learning sustainability.

Abstract: Based on quantitative predictions enabled by a nonperturbative approach to Yang-Mills thermodynamics it is explained why the physics of photon {\sl propagation} is not unlikely rooted in pure SU(2) gauge dynamics.
Sheila Jeffreys: The Industrial Vagina. The Political Economy of the Global Sex Trade. London: Routledge 2008.
Susanne Hofmann
querelles-net , 2010,
Abstract: Sheila Jeffreys analysiert die Prozesse, die zu einer Industrialisierung und Globalisierung von Prostitution im sp ten 20. und 21. Jahrhundert geführt haben. Hauptverantwortlich für die gegenw rtige Diskursverschiebung um Prostitution ist für Jeffreys zum einen die sexuelle Revolution der 1970er Jahre und zum anderen die massive Finanzierung von Unterstützer/-innen der Sexarbeiterinnen zur HIV-Pr vention in den 1980ern. Jeffreys legt wie in früheren Arbeiten ihre radikal-feministische Position dar und fordert eine Abschaffung der Prostitution. In ihrer Abrechnung mit dem liberalen feministischen Diskurs, für den eine Unterstützung von Sexarbeiterinnen priorit r ist, ignoriert sie die Widersprüchlichkeiten und Komplexit ten der gelebten Realit ten. An vielen Stellen ihres Buches bekr ftigt Jeffreys stereotypische M nnlichkeitsvorstellungen, was durch einen Blick über den Tellerrand des ihr vertrauten wissenschaftlichen Bezugsrahmens h tte vermieden werden k nnen. Sheila Jeffreys analyzes the processes that led to the industrialization and globalization of prostitution in the late 20th and 21th centuries. Jeffreys considers those primary factors responsible for the current shift in discourse on prostitution, which can be attributed to the sexual revolution of the 1970s on the one hand, and to massive financing of HIV prevention in the 1980s by sex worker supporters on the other. As in earlier studies, Jeffreys presents readers with her radical-feminist position and demands prostitution be abolished. In her confrontation with liberal-feminist discourse, in which the support of sex workers takes priority, she ignores the inconsistencies and complexities of real lived experience. At many points throughout her book, Jeffreys affirms stereotypical male conceptions, which could have been avoided had she looked beyond the theoretical frame of reference that makes up her comfort zone.
Treatment of patients with comorbid depression and diabetes with metformin and milnacipran

Abstract: Peter HofmannUniversity Clinic of Psychiatry, Graz Medical University, Graz, AustriaAbstract: Depression is twice as frequent in patients with diabetes as in the general -population, and has a negative impact on self-care, adherence to treatment, and the general prognosis of diabetes. This underscores the importance of screening all diabetic patients for depression and, if necessary, treating it with an effective antidepressant drug in parallel with standard diabetes -treatment. In a recent study, a simple two-question screening tool was used to screen diabetic patients for comorbid depression. The effects of the serotonin and norepinephrine reuptake inhibitor antidepressant, milnacipran, on metabolic parameters and depressive -symptoms in 64 diabetic patients with comorbid depression detected by this screen were -studied. Patients received -milnacipran for 6 months, in addition to standard diabetes treatment with metformin. At the end of the study, 72% of patients had responded to antidepressant treatment (≥50% reduction of baseline Beck Depression Score). The proportion of patients with <8% glycosylated hemoglobin HbA1c (a common indication in diabetes of the need for intensive therapeutic intervention) had decreased significantly from 46.6% at baseline to 6.9%. HbA1c, fasting blood glucose, body mass index, total and low-density lipoprotein cholesterol, and serum triglyceride levels were all significantly decreased in patients with an antidepressant response, but not in patients whose depressive symptoms had not responded to milnacipran.Keywords: depression, diabetes, milnacipran, serotonin, norepinephrine, reuptake inhibitors
