Architektura a ideologie. Výchovné instituce Adolfa Hitlera v protektorátu Čechy a Morava a v Říšské župě Sudety

This article examines the architecture of the Nazi regime in two occupied cities of Czechoslovakia, Praha/Prag and Jihlava/Iglau (the latter being one of the traditionally German-speaking island in the bohemia country), and focuses specifically on the process by which Hitler youth organisations (Hitlerjugend) in case of ‘education’ and indoctrination of youth were or were not successfully established in these cities. As comparison, he takes the political-administrative centres of the Sudeten Reichsgau, Ústí/Aussig, Opava/Troppau, Karlovy Vary/Karlsbad and Liberec/Reichenberg. Drawing on Czech and German archive materials, the extensive body of modern analytical literature, and propagandist literature from the period studied, the author examines the extent to which architecture served as a projection screen for Fascist propaganda in the Occupied Eastern territories. He describes the role played by the Reichsstelle für Raumordnung and shows how the Reich’s propagandist objectives came to be reflected in a high specific typology and stylistic lexicon/configuration for the architecture of Hitler youth hostels and homes He examines the process by which these organisations were powerful implanted into the space of occupied Czechoslovakia (and Sudeten) too, a topic that has not yet been addressed in (art) history too. The building projects developed for the Protectorate (published here for the first time) and managed by the Reich’s Hitler Youth Leadership in Berlin (Kulturamt, Reichsjugendführung, RJF, Abteilung HJ) reveal the ties that existed between the construction authorities in the Reich and the Protectorate, including the Planning Committee for the City of Prague. The author asks how many German and Czech architects participated for their own profit in the Nazi system, and for future research raises the hitherto taboo question of guilt and collaboration with the Nazis and the perception of this phenomenon in art history, i.e. the measure of active cooperation of not just German but also Czech architects who contributed to the planning and implementation of projects and thereby unequivocally had a hand in consolidating the totalitarian regime and de facto in the forced „Germanification” of their own people under occupation.

A prehistoric thoroughfare between the Ganges and the Himalayas

The greater Himalayan region, including the Tibetan plateau in the north and the Gangetic plain in the south, served as the principal prehistoric thoroughfare for the peopling of East and Southeast Asia. The descendants of ancient migrants through this region ultimately settled lands as far away as New Zealand, Madagascar and the Americas. Several of the keys to understanding the ethnogenesis of human diversity in Asia include the Father Tongue correlation, possible refugia during the Last Glacial Maximum and the hypothesis that language families may have arisen as the result of demographic bottlenecks in prehistory. Ethnolinguistically informed inferences based on Asian Y chromosomal phylogeography permit a reconstruction of episodes of ethnolinguistic prehistory which lie beyond the linguistic event horizon, i.e. beyond the time depth empirically accessible to historical linguistics. The origins of the language families which make up the hypothetical Uralo-Siberian and East Asian linguistic phyla are argued to have lain in the northeastern corner of the Indian subcontinent. Several other Asian language families are shown to be tied to the subcontinent. The Centripetal Migration model, which assumes that migrations in quest of a better life unfolded in both centrifugal and centripetal directions with respect to technologically more advanced centres of civilisation, is opposed to the Farming Language Dispersal theory, which assumes that all linguistic dispersals were driven by agricultural centrifugal migration.

The implicit achievement motive and general life stress affect time spent on competitive matches in racquet sports

The match time spent on court in racquet sports can be perceived as dependent on the effort an athlete is willing to exert in a competition. Achievement motivation is defined as the effort a person spends on a difficult task with the completion of which she wants to meet a personal standard of excellence, wants to improve herself, or outperform others (McClelland, Atkinson, Clark, & Lowell, 1953). Fifty-two professionals of three racquet sports (tennis, table tennis, and badminton) filled in a questionnaire on their explicit achievement motive, a scale on general life stress, and a measure of the implicit achievement motive. Results indicate that the implicit but not the explicit achievement motive was able to predict the athletes' time spent on court (effort). Additionally the general life stress scale was negatively related to time spent on court. Findings are in line with theoretical assumptions that actual behavior is linked to the implicit achievement motive and that higher levels of general life stress lead to impaired performance in sports.

Defining and measuring urban regions: A sensitivity analysis

This paper evaluates the impact of alternative city boundary definitions on economic performance. First we discuss the theoretical background and motivate the empirical work. Then we present the methodological concept of the sensitivity analysis, which will be applied to a variety of data of Zurich and Bern (the financial and the administrative centres of Switzerland) in order to see how the values of different indicators vary depending on the definition adopted. Finally we will show whether the empirical patterns found are statistically significant. The analysis shows, that the delimitation of a city or city region indeed matters.

Connecticut Poison Control Center . 2004 and 2005 Bi-Annual Report on Poisoning in Connecticut

For the past 49 years, the Connecticut Poison Control Center (CTPCC) based at the University of Connecticut Health Center (UCHC), has managed human exposures and poisonings throughout the state and continues to serve as a toxicologic center of excellence. A human exposure may be defined as contact by skin, eye, mouth or inhalation to any substance: animal, mineral or vegetable, including: bites, commercial products, chemicals, drugs, natural remedies and plants among others. A poisoning is any injury to the body resulting from an exposure. Toxicology is the scientific study of the adverse effects of any substance on the body.

Factors that affect non-adherence to first line antiretroviral medications among HIV infected children and adolescents in Botswana

The aims of the study were to determine the prevalence of and factors that affect non-adherence to first line antiretroviral (ARV) medications among HIV infected children and adolescents in Botswana. The study used secondary data from Botswana-Baylor Children's Clinical Center of Excellence for the period of June 2008 to February 10th, 2010. The study design was cross-sectional and case-comparison between non-adherent and adherent participants was used to examine the effects of socio-demographic and medication factors on non-adherence to ARV medications. A case was defined as non-adherent child with adherence level < 95% based on pill count and measurement of liquid formulations. The comparison group consisted of children with adherence levels ≥95%.^ A total of 842 participants met the eligibility criteria for determination of the prevalence of non-adherence and 338 participants (169 cases and 169 individuals) were used in the analysis to estimate the effects of factors on non-adherence. ^ Univariate and multivariable logistic regression were used to estimate the association between non-adherence (outcome) and socio-demographic and medication factors (exposures). The prevalence of non-adherence for participants on first line ARV medications was 20.0% (169/842).^ Increase in age (OR (95% CI): 1.10 (1.04–1.17) p = 0.001) was associated with nonadherence, while increase in number of caregivers (OR (95% CI): 0.72 (0.56–0.93) p = 0.01) and increase in number of monthly visits (OR (95% CI): 0.92 (0.86–0.99) p = 0.02), were associated with good adherence in both the unadjusted and the adjusted models. For the categorical variables, having more than two caregivers (OR (95% CI): 0.66 (0.28–0.84), p = 0.002) was associated with good adherence even in the adjusted model. ^ Conclusion. The prevalence of non-adherence to antiretroviral medicines among the study population was estimated to be 20.0%. In previous studies, adherence levels of ≥ 95% have been associated with better clinical outcomes and suppression of virus to prevent development of resistance. Older age, fewer numbers of caregivers and fewer monthly visits were associated with non-adherence. Strategies to improve and sustain adherence especially among older children are needed. The role of caregivers and social support should be investigated further.^

Todo cambia. Potrerillos también y tiene su historia

Potrerillos, es uno de los centros turísticos de mayor importancia de área de alta montaña mendocina, y ha comenzado un nuevo período de su historia a partir del momento en que se toma la decisión de comenzar a construir la Presa. No obstante, las ventajas que se esperan, es innegable los enormes cambios para los habitantes permanentes del valle de Potrerillos, especialmente los de la villa cabecera, quienes deben abandonar sus viviendas y en algunos casos su actividad, su medio de vida, para ser reubicados en otro emplazamiento cercano, pero de características muy diferentes a las que eran habituales para estos montañeses, quienes en muchos casos han vivido por generaciones en la zona. Para dar afirmación social y cultural a los lugareños es indispensable poner en juego valores de complementariedad y solidaridad, de respeto por los saberes del pasado y por el sentir estético de dichas personas. Debería pensarse en nuevas técnicas para ayudarles a emprender nuevas actividades económicas acordes con sus gustos y no necesariamente orientadas a la elaboración de pan o empanadas para los turistas que se acercan al nuevo barrio. Debemos integrarlos a todo el proceso de cambio, no sólo apartarlos para obtener el espacio.

El alumnado con TDAH (hiperactividad) como colectivo en riesgo de exclusión social: propuestas de acción y de mejora

La hiperactividad es algo más que un trastorno simple, negativo y defectuoso. Las personas con TDAH tienen un potencial latente del que nadie habla (como la creatividad, el ingenio, la hiperconcentración, la sensibilidad, entre otros). Ser hiperactivo es positivo si tenemos la habilidad de comprender y tratar el trastorno desde una perspectiva educativa diferente ya que el alumnado con TDAH es uno de los colectivos que suman más amonestaciones, sanciones y expulsiones en los centros educativos de nuestro país. Sin embargo, estos niños pueden tener éxito académico y, posteriormente, en su vida laboral y afectiva, si previamente hemos sabido comprenderlos y actuar con un proceso educativo adecuado a su idiosincrasia y si hemos sabido otorgar cierto grado de organización y reencauzamiento en sus mentes a veces infravaloradas. Para ello, las administraciones públicas educativas deben desarrollar estrategias de formación eficientes para formar a un profesorado que, muchas veces, asiste desorientado e impotente a un comportamiento caótico, desordenado e impulsivo que puede provocar serios conflictos no sólo en la enseñanza sino en el mismo clima de convivencia escolar.

Seawater carbonate chemistry, calcification and respiration duirng experiments with a pteropod Creseis acicula, 2010

Among marine calcifiers, shelled pteropods are expected to be particularly sensitive to ocean acidification, generated by the uptake of anthropogenic CO2 by the ocean, and the associated decrease of the seawater saturation state with respect to aragonite (omega aragonite). The few available studies have mostly focused on polar species although pteropods are also important components of temperate and tropical ecosystems. It is also unknown which parameter of the carbonate system controls calcification. Specimens of the temperate Mediterranean species Creseis acicula were maintained under seven different conditions of the carbonate chemistry, obtained by manipulating pH and total alkalinity, with the goal to disentangle the effects of pH and omega aragonite. Respiration, excretion as well as rates of net and gross calcification were not directly affected by a decrease in pH but decreased significantly with a decrease of omega aragonite. The decrease of gross calcification rates is consistent with that reported for polar species. Although the organisms were apparently able to maintain gross calcification rates under slightly undersaturated aragonite conditions, the clear net dissolution signal observed below saturation suggests that they are not able to build a shell in seawater corrosive to aragonite. The decrease in respiration and excretion, and the low O:N molar ratio, could be due to the short time that the organisms were allowed to acclimatize to their new environment.

Seawater carbonate chemistry, Acropora digitifera growth and skeletal U/Ca ratios during experiments, 2011

The impact of ocean acidification caused by the increasing atmospheric CO2 has been studied in marine calcifiers, including hermatypic corals. However, the effect of elevated pCO2 on the early developmental life-cycle stage of corals has been little studied. In this study, we reared polyps of Acropora digitifera in seawater at pHT 6.55, 7.31, 7.64, 7.77, and 8.03, controlled by CO2 bubbling. We measured the dry weights of polyp skeletons after the 40-d experiment to investigate the relationship between the seawater aragonite saturation state and polyp growth. In addition, we measured skeletal U/Ca ratio to estimate their pH dependence. Skeletal weights of coral polyps increased with the aragonite saturation state and reached an apparent saturation plateau above pH 7.77. U/Ca ratios had a strong inverse relationship with pH and a negligible relationship with skeletal growth rate (polyp weight), suggesting that skeletal U/Ca could be useful for reconstructing paleo-pH.

Seawater carbonate chemistry, pigments and proteins during experiments with phytoplankton, 2010

In the high-nutrient, low-chlorophyll waters of the Gulf of Alaska, microcosm manipulation experiments were used to assess the effect of CO2 on growth and primary production under iron-limited and iron-replete conditions. As expected, iron had a strong effect on growth and photosynthesis. A modest and variable stimulation of growth and biomass production by CO2 (high CO2: 77-122 Pa; low CO2: 11-17 Pa) was observed under both iron-replete and iron-limited conditions, though near the limit of precision of our measurements in slow-growing low-iron experiments. Physiological acclimations responsible for the changes in growth were assessed. Under iron-limited conditions, growth stimulation at high CO2 appeared to result from an increase in photosynthetic efficiency, which we attribute to energy savings from down-regulation of the carbon concentrating mechanisms. In some cases, iron-rich photosynthetic proteins (PsbA, PsaC, and cytochrome b6) were down-regulated at elevated CO2in iron-limited controls. Under iron-replete conditions, there was an increase in growth rate and biomass at high CO2 in some experiments. This increase was unexpectedly supported by reductions in cellular carbon loss, most likely decreased respiration. We speculate that this effect may be due to acclimation to decreased pH rather than high CO2. The variability in responses to CO2 among experiments did not appear to be caused by differences in phytoplankton community structure and may reflect the sensitivity of the net response of phytoplankton to antagonistic effects of the several parameters that co-vary with CO2.

Seawater carbonate chemistry and Globigerinoides sacculifer biological processes during experiments, 2010

The effect of carbonate ion concentration ([CO3]) on calcification rates estimated from shell size and weight was investigated in the planktonic foraminifera Orbulina universa and Globigerinoides sacculifer. Experiments on G. sacculifer were conducted under two irradiance levels (35 and 335 µmol photons m-2 s-1). Calcification was ca. 30% lower under low light than under high light, irrespective of the [CO3]. Both O. universa and G. sacculifer exhibited reduced final shell weight and calcification rate under low [CO3]. For the [CO3] expected at the end of the century, the calcification rates of these two species are projected to be 6 to 13% lower than the present conditions, while the final shell weights are reduced by 20 to 27% for O. universa and by 4 to 6% for G. sacculifer. These results indicate that ocean acidification would impact on calcite production by foraminifera and may decrease the calcite flux contribution from these organisms.

Seawater carbonate chemistry and dissolution rates by boring microflora during ex situ experiments with dead corals (Porites lobata), 2009

Eight-month-old blocks of the coral Porites lobata colonized by natural Hawaiian euendolithic and epilithic communities were experimentally exposed to two different aqueous pCO2 treatments, 400 ppmv and 750 ppmv, for 3 months. The chlorophyte Ostreobium quekettii dominated communities at the start and at the end of the experiment (65-90%). There were no significant differences in the relative abundance of euendolithic species, nor were there any differences in bioeroded area at the surface of blocks (27%) between pCO2 treatments. The depth of penetration of filaments of O. quekettii was, however, significantly higher under 750 ppmv (1.4 mm) than under 400 ppmv (1 mm). Consequently, rates of carbonate dissolution measured under elevated pCO2 were 48% higher than under ambient pCO2 (0.46 kg CaCO3 dissolved m2/a versus 0.31 kg /m2/a). Thus, biogenic dissolution of carbonates by euendoliths in coral reefs may be a dominant mechanism of carbonate dissolution in a more acidic ocean.

Seawater carbonate chemistry and processes during experiments with crabs Chionoecetes tanneri and Cancer magister, 2007

Rising levels of atmospheric carbon dioxide could be curbed by large-scale sequestration of CO2 in the deep sea. Such a solution requires prior assessment of the impact of hypercapnic, acidic seawater on deep-sea fauna. Laboratory studies were conducted to assess the short-term hypercapnic tolerance of the deep-sea Tanner crab Chionoecetes tanneri, collected from 1000 m depth in Monterey Canyon off the coast of central California, USA. Hemolymph acid- base parameters were monitored over 24 h of exposure to seawater equilibrated with ~1% CO2 (seawater PCO2 ~6 torr or 0.8 kPa, pH 7.1), and compared with those of the shallow-living Dungeness crab Cancer magister. Short-term hypercapnia-induced acidosis in the hemolymph of Chionoecetes tanneri was almost uncompensated, with a net 24 h pH reduction of 0.32 units and a net bicarbonate accumulation of only 3 mM. Under simultaneous hypercapnia and hypoxia, short-term extracellular acidosis in Chionoecetes tanneri was completely uncompensated. In contrast, Cancer magister fully recovered its hemolymph pH over 24 h of hypercapnic exposure by net accumulation of 12 mM bicarbonate from the surrounding medium. The data support the hypothesis that deep-sea animals, which are adapted to a stable environment and exhibit reduced metabolic rates, lack the short-term acid-base regulatory capacity to cope with the acute hypercapnic stress that would accompany large-scale CO2 sequestration. Additionally, the data indicate that sequestration in oxygen-poor areas of the ocean would be even more detrimental to deep-sea fauna.
