Psychological and Psychophysiological Effects of a High-Mountain Expedition to Tibet
No full textIn March 1999 a team of 8 mountaineers (6 men and 2 women) climbed up the 6th highest mountain of the world: The Cho Oyo (8201 m), located in the high mountains of Tibet. During the expedition, we investigated the effects of high mountaineering on various psychological variables (e.g., anxiety) and psychophysiological variables (e.g. blood pressure, pulse, skin-resistance) as well as the ability to relax at different points of time (2 premeasures before, three measures during, and one post-measure immediate after the Expedition). Due to a long-term monitoring of the skin resistance, we can summarize that three different adaptation levels can be defined, that appear under increasing pressure: Inhibition of overload, unspecific hypersensibility and exhaustion. The results can show that a telemedical assessment is possible and necessary even under the circumstances of a highmountaineering expedition in order to determine and predict deficits in behaviour and health risks for individuals at high altitudes
Safety of contrast-enhanced MR angiography employing gadobutrol 1.0 M as contrast material
No full textOur objectives were to evaluate the safety of intravenous 1.0-M gadobutrol injections in patients with an indication for contrast-enhanced magnetic resonance angiography (CE MRA) of supra-aortal, pelvic, or peripheral arteries by examining and assessing adverse events, laboratory values, vital signs and ECG findings for clinical significance. In 435 patients, recruited in three multicenter trials for safety evaluations of the new contrast agent 1.0-M gadobutrol, CE MRA was performed with 1.0- to 1.5-T scanners using three-dimensional gradient-echo sequences and phased-array coils. The study population comprised 312 men and 123 women with a mean age of 60.9 years. Two hundred seven patients had an indication for imaging of body arteries and 228 had an indication for imaging of peripheral arteries. Blood laboratory values and urinalysis results of 124 patients as well as heart rate, blood pressure, and 12-lead-electrocardiogram readings of 93 patients obtained during a follow-up period of up to 72 h after the injection of contrast media were available for safety analysis. Contrast media application was performed as intravenous bolus injection of 1.0-M gadobutrol in fixed doses according to the patients' body weight (b.w.) and indication for CE MRA and was followed by a 20- to 40-ml saline flush. Mean dose actually applied was 0.10.27 mmol/kg b.w. Flow rate ranged between 0.2 and 2.0 ml/s. Safety evaluations found a good tolerability with only 4.6% of at least "possibly related" adverse reactions and no clinically relevant changes in blood and urine samples including no transmetallation effect on serum zinc values. Analysis of renal tolerance showed no influence on renal function irrespective of preexisting renal impairment. The ECG analysis (rhythm analysis, pace-setting disturbances, conduction disturbances, and time interval measurements, including uncorrected and corrected QT) showed no clinically relevant effect of the injection of 1.0-M gadobutrol on the cardiac conduction system. Intravenous injection of 1.0-M gadobutrol at a dose of up to 0.1 0.27 mmol/kg b.w. in the indication CE MRA is safe and causes no clinically relevant changes in safety parameters such as heart rate, blood pressure, blood and urine laboratory values, and cardiac conduction system
Vessel charter rate estimation for offshore wind O&M activities
No full textEstimating the cost of vessels is an important factor for the operation & maintenance (O&M) costs of offshore wind farms. Accurate cost estimation is required during operation of the wind farm. This paper presents the development of the O&M charter rate modelling for offshore wind turbine jack-up vessels under different op-erational strategies. The main objectives of this modelling are to explore the differentiation of charter rates as-sociated with the charter periods and with the capabilities of different vessels; as well as to allow offshore wind farm operators to plan their maintenance strategies through considering the share of vessels’ costs in the overall maintenance costs. In this respect, various jack-up vessels in the offshore wind industry are investigat-ed and the most effective charter periods are identified. The seasonal effects on the charter rates are also con-sidered to provide critical insight into the selection of the optimum charter rate scenario
O miejsce historii prawa w programie studiów uniwersyteckich. Polemika między Oswaldem Balzerem a Juliuszem Makarewiczem (1919-1923)
No full textOswald Balzer i Juliusz Makarewicz to wybitni polscy prawnicy. Pierwszy z nich był historykiem prawa i ustroju, drugi - mimo, iż także nieobce były mu zagadnienia prawno-historyczne - zapisał się w dziejach polskiej nauki jako specjalista prawa karnego, jeden z głównych twórców Kodeksu karnego z 1932 r., zwanego od jego nazwiska „kodeksem Makarewicza”. Jakkolwiek obu uczonych łączył pogląd o konieczności zapewnienia polskiej nauce prawa należnego jej miejsca w systemie oświaty Odrodzonej Rzeczypospolitej, to jednakowoż dzieliło spojrzenie na kolejność uniwersyteckiego kształcenia prawników. W sporze tym chodziło zwłaszcza o miejsce studium prawno-historycznego w toku wykładów uniwersyteckich. Jeśli O. Balzer głosił konieczność rozpoczynania nauki od wykładu historii prawa, to J. Makarewicz zajmował stanowisko wprost przeciwne - według niego wykład ten miał być „koroną” wykształcenia prawniczego. Uczeni na poparcie swych tez przedkładali wiele interesujących argumentów. Uwagę zwraca, iż dysputa profesorów, pracujących przecież na jednym wydziale, toczyła się na forum ogólnokrajowym. Miała ona miejsce w latach 1919-1923; artykuły ukazywały się przede wszystkim na łamach „Przeglądu Prawa i Administracji”, były publikowane także w formie nadbitek i osobnych broszur
Carmen Balzer : su quehacer filosófico
No full textResumen: Buscadora incansable, que ha desenvuelto sus búsquedas principalmente en
el ámbito del arte y en el de lo religioso, se ha adentrado en dichos ámbitos
sabedora de su propio límite como existente y en y desde su aspiración filosófica a ahondar en el Ser, el Fundamento. Acaso sea su aspiración al Fundamento, su aspiración a ahondar en él, en y
desde su quehacer filosófico, y el saboreo del límite de dicho quehacer, el límite
de la filosofía misma, lo que haya suscitado una actitud abierta en su búsqueda
filosófica. Búsqueda filosófica desde la cual se ha abierto al arte, a la expresión
poética, a la mística y a la religión.
En su obra Arte, Fantasía y Mundo
, obra densa, queremos resaltar la recurrencia de nuestra autora a la obra de J. Huizinga
, Homo Ludens.
En efecto, el hombre es desde su ser mismo jugador; o mejor el existente juega
la libertad, juega la libertad que él como existente es
Verbal memory declines more in female patients with Parkinson's disease: The importance of gender-corrected normative data
No full textData on gender-specific profiles of cognitive functions in patients with Parkinson's disease (PD) are rare and inconsistent, and possible disease-confounding factors have been insufficiently considered.The LANDSCAPE study on cognition in PD enrolled 656 PD patients (267 without cognitive impairment, 66% male; 292 with mild cognitive impairment, 69% male; 97 with PD dementia, 69% male). Raw values and age-, education-, and gender-corrected Z scores of a neuropsychological test battery (CERAD-Plus) were compared between genders. Motor symptoms, disease duration, l-dopa equivalent daily dose, depression - and additionally age and education for the raw value analysis - were taken as covariates.Raw-score analysis replicated results of previous studies in that female PD patients were superior in verbal memory (word list learning, p = 0.02; recall, p = 0.03), while men outperformed women in visuoconstruction (p = 0.002) and figural memory (p = 0.005). In contrast, gender-corrected Z scores showed that men were superior in verbal memory (word list learning, p = 0.02; recall, p = 0.02; recognition, p = 0.04), while no difference was found for visuospatial tests. This picture could be observed both in the overall analysis of PD patients as well as in a differentiated group analysis.Normative data corrected for gender and other sociodemographic variables are relevant, since they may elucidate a markedly different cognitive profile compared to raw scores. Our study also suggests that verbal memory decline is stronger in women than in men with PD. Future studies are needed to replicate these findings, examine the progression of gender-specific cognitive decline in PD and define different underlying mechanisms of this dysfunction
Planetary stewardship in an urbanizing world: beyond city limits
No full textCities are rapidly increasing in importance as a major factor shaping the Earth system, and as such must take corresponding responsibility. With currently over half of the world population, cities are supported by resources originating from primarily rural regions that are often located around the world far distant from the urban loci of use. The multiple and complex environmental and social challenges the world faces require interconnected solutions and a coordinated governance approach to planetary stewardship. There is a new opportunity to conceptualize a key component of planetary stewardship as a global system of cities that develop sustainable processes and policies in concert with its non-urban areas. The potential for cities to cooperate as a system and with rural connectivity could not only increase their capacity to effect change and foster stewardship at the planetary scale but also increase their resource security
O PROFESSOR-GESTOR EM UNIVERSIDADES FEDERAIS: ALGUNS APONTAMENTOS E REFLEXÕES
No full textBuscou-se discutir que o professor de ensino superior nas universidades federais agora não é apenas docente e pesquisador, mas tem de ser, por vezes, professor-gestor (academic manager). Nessas situações ele enfrenta desafios, alguns decorrentes de lacunas no desenvolvimento de suas competências gerenciais, os quais mereceram algumas reflexões. Como possível caminho são apontados modelos de competências gerenciais para o professor de ensino superior, com ênfase no framework analítico de Mendonça et al. (2012). Considera-se que preparar professores de ensino superior para atuarem como dirigentes das universidades federais implica em formá-los considerando as competências gerenciais que se esperam deles como professor-gestor. Esse movimento não é importante somente para o alcance de níveis de excelência no ensino, pesquisa e extensão no sistema de ensino superior no Brasil, mas também para que as universidades federais possam cumprir sua missão junto à sociedade
A INTERAÇÃO ENTRE O PAPEL DE PROFESSOR-GESTOR E COMPETÊNCIAS GERENCIAIS: PERCEPÇÕES DOS PROFESSORES DE UMA UNIVERSIDADE FEDERAL
No full textO trabalho busca analisar como se dá a interação entre papel de professor-gestor e as competências gerenciais. Argumenta-se que o papel social de professor-gestor é composto pelas competências gerenciais, as quais, em algum aspecto, são diferentes das competências exigidas em outras facetas do papel de professor do ensino superior. O estudo foi de abordagem qualitativa e os dados foram coletados por meio de entrevistas semiestruturadas com professores-gestores da Universidade Federal do Vale do São Francisco (Univasf). A análise de conteúdo, com o suporte do software Atlas.ti, foi adotada para análise dos dados. Os professores-gestores da Univasf associam competência a uma família de tarefas ou de situações, como também, consideram necessárias as competências profissionais específicas para os que desempenham ou irão desempenhar o papel de gestor. A opção por pesquisar sobre o papel de gestor emergiu da necessidade de se estudar os professores de ensino superior para além das abordagens que tradicionalmente lhes atribuem os papéis de docente e de pesquisador. Buscou-se potencializar a interdisciplinaridade entre campos de conhecimentos, nomeadamente a Administração, a Educação, a Sociologia, a Psicologia e a Gestão Pública
