Rediscovering Fritz Redl
No full textIf there was a Hall of Fame for Child and Youth Care practitioners, the first person I would nominate is Fritz Redl. I had been in the field for two years when I first read Children Who Hate, and I was amazed at the description of youth that so accurately mirrored my own experience. Fritz and fellow author David Wineman explained CYC ideas better than anyone I had ever met. The complexity of our work and the use of life spaces to create healing came alive in the descriptions of his work at Pioneer House, a group home for boys

Apolipoprotein D Concentration in Human Plasma during Aging and in Parkinson’s Disease: A Cross-Sectional Study
No full textApolipoprotein D (ApoD), a lipocalin transporter of small hydrophobic molecules, plays an important role in several neurodegenerative diseases. ApoD is expressed in and secreted from a variety of peripheral and brain tissues. Increments of ApoD have been reported in relation with oxidative stress conditions, aging, and degeneration in the nervous system. Preliminary findings support the role of ApoD in neuroprotection. However, its role in PD remains unclear. To date, no studies have been performed on the relationship between ApoD in the blood and PD, as neurodegenerative pathology related to oxidative damage. We investigated the concentration of ApoD in the blood of healthy control subjects and PD patients with mild-to-moderate neurological impairment. ApoD plasma levels were measured using sandwich enzyme-linked immunosorbent assays (ELISA) in 90 healthy subjects (aging-analysis cohort) and in 66 PD patients at different stages compared with 19 age-matched healthy subjects. Significant age-related increase of ApoD was detected in subjects older than 65 years of age (p<0.002). In PD patients, a significant increase in ApoD plasma concentration was found compared with healthy subjects of the same age (p<0.05). ApoD and PD stage are significantly correlated (p<0.05). ApoD might be a valid marker for the progression of PD
Pułkownik Redl. Polityczne wątki afery w prasie polskiej
No full textThe most famous spy scandal before the outbreak of the First World War, took place during the time of intensified diplomatic actions taken to stop the Balkan War. At night on May 24th 1913, Colonel Alfred Redl, the chief of staff for the VIII. Corps stationed in Prague – having been exposed by counterintelligence – committed suicide in Klomser Hotel in Vienna. His death was directly connected to the fact that the special commission that consisted of high ranking officers was established in the extraordinary mode. The case of Russian spy was known only to an exclusive group of ‘initiates’. Nevertheless, it was almost immediately leaked to the press and evoked scandal that stirred up public opinion in Austria-Hungary. The motifs of the scandal – described in Polish press releases of that time: in Cracow, Lvov and Warsaw – have been analyzed in the article. They were significant in the context of political struggle, led mainly between two antagonistic forces: the Austrophiles and the Russophiles. Seemingly distant from Polish matters, the spy affair turned out to be an important factor that ‘catalyzed’ political attitudes of the Poles. The aspect of Redl’s nationality became a significant element of the polemics. And the scandal undermined Austro-Hungarian morale, especially the morale of Slavic nations subject to the Empire; the more so as, at exactly the same time, a political corruption affair which Hungarian Prime Minister was involved in, happened in Budapest. The events that happened in Galicia in May and June 1913 – as connected with political and economical turning point that autonomous country reached, which was caused by Austro-Hungarian preparations for Balkan War – have been examined here as the background context. In this article, basing on a wide range of press sources, the author classifies and describes some key political motifs of the Redl affair: especially the change of ideas about the Balkan War – in accordance to common opinions expressed in Polish press – now bringing the fatal threat to Austro-Hungary. (Russia came into possession of mobilization plans). The other topics are: the decline of Austro-Hungarian prestige on the international arena, the criticism of the code applying to officer corps, assigning Redl the Jewish origin by the anti-Semitic press, attacks on the ones that supported Austro-Hungarian orientations, including those who organized a kind of ‘substitute” for Polish military forces under the auspices of the monarchy, and finally – the spy psychosis.The most famous spy scandal before the outbreak of the First World War, took place during the time of intensified diplomatic actions taken to stop the Balkan War.

Physiotherapeutic Approaches for the Treatment of Osteoporotic Changes in Spinal Cord Injuries
No full textKontext und Fragestellung: Osteoporose stellt eine häufige Sekundärkomplikation nach Rückenmarksverletzungen dar und ist mit einem erhöhten Frakturrisiko verbunden. Physi-otherapeutische Maßnahmen könnten zur Reduktion osteoporotischer Veränderungen beitragen. Derzeit fehlt jedoch eine evidenzbasierte Empfehlung hinsichtlich spezifischer Therapieansätze. Ziel dieser Arbeit ist es, den aktuellen Forschungsstand zu analysieren und den Einfluss physiotherapeutischer Interventionen auf die Knochendichte (BMD) zu untersuchen.
Methode: Zur Beantwortung der Forschungsfrage wurde ein narrativer Review gewählt. Dafür erfolgte eine umfassende Literatursuche in den Datenbanken PubMed und PEDro. Die Literaturrecherche erfolgte anhand eines Screening-Verfahrens und definierter Ein- und Ausschlusskriterien.
Hauptergebnisse: Es wurden 9 Studien in den Ergebnissen eingeschlossen. Diese zeigen, dass physiotherapeutische Maßnahmen, wie belastungsorientierte Interventionen sowie funktionelle Elektrostimulation auf einem Fahrradergometer (FESCE) effektiv zur Erhal-tung der BMD nach einer Rückenmarksverletzung sind. Passive Methoden wie Elektros-timulation, Ultraschall und Vibration zeigen hingegen wenig Wirkung.
Schlussfolgerung: Frühzeitige, aktive Interventionen wie FESCE und Belastungstraining sind entscheidend für den Knochenerhalt nach einer Rückenmarksverletzung, während passive Methoden nur unterstützend eingesetzt werden sollten.Context and research question: Osteoporosis is a common secondary complication follow-ing spinal cord injuries and is associated with an increased risk of fractures. Physiothera-peutic interventions may contribute to the reduction of osteoporotic changes. However, there is currently no evidence-based recommendation regarding specific therapeutic ap-proaches. The aim of this study is to analyze the current state of research and investigate the impact of physiotherapeutic interventions on bone mineral density (BMD).
Method: A narrative review was chosen to address the research question. A comprehen-sive literature search was conducted in the PubMed and PEDro databases. The literature review was performed using a screening process and defined inclusion and exclusion cri-teria.
Results: Nine studies were included in the results. These show that physiotherapeutic inter-ventions, such as load-oriented exercises and functional electrical stimulation on a cycle ergometer (FESCE), are effective in maintaining BMD after a spinal cord injury. In con-trast, passive methods such as electrical stimulation, ultrasound, and vibration show little effect.
Conclusion: Early, active interventions such as FESCE and load-bearing training are cru-cial for bone preservation following a spinal cord injury, while passive methods should only be used as supplementary treatments
Service-Learning and Character Education as Antidotes for children with egos that cannot perform
No full textThe author describes an after-school service-learning and character education program for students with emotional, behavioral, and learning problems and there nondisabled peers. SO Prepared for Citizenship honors the memory and tradition of Dr. Fritz Redl and David Wineman 50 years after the publication of their book, Children Who Hate. Written in the style of that classic book, this article describes the characteristics of students who have “egos that cannot perform” and program strategies designed to help children and adolescents develop controls from within
A Study of University Timetabling that Blends Graph Coloring with the Satisfaction of Various Essential and Preferential Conditions
No full textThis work was also published as a Rice University thesis/dissertation: http://hdl.handle.net/1911/18687Constructing a satisfactory conflict-free semester-long timetable of courses and creating a similarly satisfactory conflict-free timetable for end-of-semester final examinations are two closely related and often difficult problems that colleges and universities face each semester. We discuss the relevance of such timetabling problems as a natural and practical application of graph coloring, and develop a mathematical and computational model for solving university timetabling problems using techniques of graph coloring that incorporates the satisfaction of both "essential" timetabling conditions (i.e., conditions or constraints that must be satisfied in order to produce a legal or feasible timetable) as well as suggested "preferential" timetabling conditions (i.e., additional conditions or constraints that need not necessarily be satisfied to produce a legal or legitimate timetable, but if satisfied may very well produce a more ''acceptable'' timetable for students and/or faculty members). We discuss in detail the step-by-step process that is taken to implement our timetabling-by-graph-coloring procedure, from the assembling of university course data, to creating a course conflict graph based on the assembled data, to coloring the conflict graph, to transforming this coloring to a conflict-free timetable, to finally assigning courses to classrooms. Once a conflict-free timetable of courses has been constructed, we present ways in which such a course timetable for a particular semester can be used to construct a conflict-free timetable of final examinations. Our model also considers a number of sociological scheduling concerns and preferences addressed by university registrars, faculty, staff, and students. Computational results, obtained by the author using actual data provided by Rice University and the University of St. Thomas, are documented

Thermodynamics and economic feasibility of acetone production from syngas using the thermophilic production host Moorella thermoacetica
No full textBackground: Syngas fermentation is a promising option for the production of biocommodities due to its abundance and compatibility with anaerobic fermentation. Using thermophilic production strains in a syngas fermentation process allows recovery of products with low boiling point from the off-gas via condensation. Results: In this study we analyzed the production of acetone from syngas with the hypothetical production host derived from Moorella thermoacetica in a bubble column reactor at 60 degrees C with respect to thermodynamic and economic feasibility. We determined the cost of syngas production from basic oxygen furnace (BOF) process gas, from natural gas, and from corn stover and identified BOF gas as an economically interesting source for syngas. Taking gasliquid mass transfer limitations into account, we applied a thermodynamics approach to derive the CO to acetone conversion rate under the process conditions. We estimated variable costs of production of 389 /t acetone, respectively). Conclusion: We applied an approach of combining thermodynamic and economic assessment to analyze a hypothetical bioprocess in which the volatile product acetone is produced from syngas with a thermophilic microorganism. Our model allowed us to identify process metrics and quantify the variable production costs for different scenarios. Economical production of bulk chemicals is challenging, making rigorous thermodynamic/economic modeling critical before undertaking an experimental program and as an ongoing guide during the program. We intend this study to give an incentive to apply the demonstrated approach to other bioproduction processes

Blaufuss, F. Halzen, C. Kopper (Changed to add one missing author, no other changes from initial version.)The recent observation by the IceCube neutrino observatory of an astrophysical flux of neutrinos represents the "first light" in the nascent field of neutrino astronomy. The observed diffuse neutrino flux seems to suggest a much larger level of hadronic activity in the non-thermal universe than previously thought and suggests a rich discovery potential for a larger neutrino observatory. This document presents a vision for an substantial expansion of the current IceCube detector, IceCube-Gen2, including the aim of instrumenting a volume of clear glacial ice at the South Pole to deliver substantial increases in the astrophysical neutrino sample for all flavors. A detector of this size would have a rich physics program with the goal to resolve the sources of these astrophysical neutrinos, discover GZK neutrinos, and be a leading observatory in future multi-messenger astronomy programs
