O trabalho pretende discutir o duplo caráter das obras de arte a partir da obra de Theodor W. Adorno. Pretende-se examinar os argumentos sustentados pelo autor sobre o caráter social das obras, principalmente, no caso da música, em que se pode percebercomo o desenvolvimento do próprio material musical expressa as aporias encontradas na sociedade. Por meio de uma crítica dialética, modo pelo qual as obras de arte respondem às contradições da sociedade, colocando-se, assim, como força de resistência à reificação, quanto a influência negativa que sofrem, porexemplo, no contexto da indústria cultural. Além disso, o artigo pretende se dedicar à reflexão sobre a autonomia das obras de arte, qualidade que as mantém fechadas, desenvolvendo-se apenas segundo leis formais internas, sem que atendam a uma função social. É nesse sentido quese coloca a exigência de uma determinada forma de recepção dasobras, orientada não pela fruição, mas pela possibilidade de interpretar seu teor de verdade. Assim, a dialética presente no modo como as obras se relacionam com a sociedade torna possível concebê-las como possibilidade de crítica à realidade e de resistência à reificação.
Fluctuations of the water level at the edges of temporary water bodies provide favourable living conditions for annual plant communities of the phytosociological class Isoëto-Nanojuncetea. Such communities of periodically flooded ponds within the agricultural landscape of NE Germany are particularly rich in rare plant species of that class. During the past decades drainage, fertilisation and herbicides in the surrounding arable fields have led to a severe decline in diversity of these species. To develop efficient conservation strategies it is essential to understand the factors driving the species composition. Therefore, we studied how varying water regimes, soil properties and agricultural practices affect the diversity and species composition of these temporary ponds. The study was carried out in seven ponds on a conventionally managed farm in NE Brandenburg. At each of these wetlands mixed soil samples were taken to determine the pH, total nitrogen and phosphorus concentration. The plant species were recorded in 177 plots, each covering 1 x 1 m2. For each plot, the water level was recorded in April, July and August 2013, respectively, resulting in five "water level regimes". Total species number and percentages of Isoëto-Nanojuncetea species were determined per plot, to evaluate water level effects on the vegetation. In addition, mean Ellenberg indicator values for light, moisture and nutrients were calculated to assess the environmental conditions.

Global Governance ist in: Klingt neuartig, global ist eigentlich auch alles und wer will sich schon vorwerfen lassen, noch im „methodologischen Nationalismus“ verhaftet zu sein? Dies ist überspitzt formuliert, doch wie sich zeigte nicht ganz unberechtigt. Nichtsdestotrotz waren die OrganisatorInnen des ersten Weltkongresses der International Association of Political Science Students (IAPSS) wohl selbst überrascht als zur Tagung mit dem Titel „The Limits of Global Governance“ rund 200 Anmeldungen von Studierenden kamen. In Thessaloniki, der europäischen Jugendhauptstadt 2014, wurde vier Tage über Global Governance debattiert und in den insgesamt sieben studentischen Panels, zahlreichen Vorträgen von etablierten WissenschaftlerInnen und weiteren Veranstaltungen zeigte sich vor allem die Vielfalt und Breite des Themas. Wir werden daher im Folgenden Schlaglichter auf interessante Veranstaltungen und Inhalte werfen und abschließend ein kritisch-konstruktives Fazit der Tagung ziehen.
Autor, motiviran ponajprije poznatom pretpostavkom o tome da je Marko Marulić možda studirao pravne znanosti, prvo daje pregled dosadašnjih ograničenih pokušaja da se govori o pravnoj terminologiji u Marulićevu opusu na hrvatskom jeziku. Poslije se, s obzirom na to da se u prikazanoj literaturi katkada implicira (ali i eksplicira) da se Marulić koristi tim terminima zato što je bio pravnik, pretragom spomenutog opusa u potrazi za potencijalnim pravnim terminima pokušava utvrditi može li se takvo razmišljanje bolje potkrijepiti ili pak opovrgnuti. Na kraju se raspravlja o metodološkim problemima, ograničenjima, ali i mogućnostima poboljšanja takvih filoloških istraživanja.
Im Aufsatz versucht der Autor, nach einer textgestützten Interpretation von Martial II 51, zu zeigen, wie der Epigrammatiker die Fabel des augusteischen Historikers Livius vom Magen und den Gliedern (II 32,9ff.) in eine frivole Parodie überführt und sie zu einer witzigen und grotesken Karikatur verformt – ein spöttisches Spiel mit gattungs- und literaturgeschichtlichen Elementen.
Does the rotten child spoil his companion? : spatial peer effects among children in rural India
(2014)
This paper identifies the effect of neighborhood peer groups on childhood skill acquisition using observational data. We incorporate spatial peer interaction, defined as a child's nearest geographical neighbors, into a production function of child cognitive development in Andhra Pradesh, India. Our peer group definition takes the form of networks, whose structure allows us to identify endogenous peer effects and contextual effects separately. We exploit variation over time to avoid confounding correlated with social effects. Our results suggest that spatial peer and neighborhood effects are strongly positively associated with a child's cognitive skill formation. Further, we explore the effect of peer groups in helping to provide insurance against the negative impact of idiosyncratic shocks to child learning. We find that the data reject full risk-sharing, but cannot rule out the existence of partial risk-sharing on behalf of peers. We show that peer effects are robust to different specifications of peer interactions and investigate the sensitivity of our estimates to potential misspecification of the network structure using Monte Carlo experiments.
Objectives: Low energy shock waves have been shown to induce angiogenesis, improve left ventricular ejection fraction and decrease angina symptoms in patients suffering from chronic ischemic heart disease. Whether there is as well an effect in acute ischemia was not yet investigated.
Methods: Hind-limb ischemia was induced in 10–12 weeks old male C57/Bl6 wild-type mice by excision of the left femoral artery. Animals were randomly divided in a treatment group (SWT, 300 shock waves at 0.1 mJ/mm2, 5 Hz) and untreated controls (CTR), n = 10 per group. The treatment group received shock wave therapy immediately after surgery.
Results: Higher gene expression and protein levels of angiogenic factors VEGF-A and PlGF, as well as their receptors Flt-1 and KDR have been found. This resulted in significantly more vessels per high-power field in SWT compared to controls. Improvement of blood perfusion in treatment animals was confirmed by laser Doppler perfusion imaging. Receptor tyrosine kinase profiler revealed significant phosphorylation of VEGF receptor 2 as an underlying mechanism of action. The effect of VEGF signaling was abolished upon incubation with a VEGFR2 inhibitor indicating that the effect is indeed VEGFR 2 dependent.
Conclusions: Low energy shock wave treatment induces angiogenesis in acute ischemia via VEGF receptor 2 stimulation and shows the same promising effects as known from chronic myocardial ischemia. It may therefore develop as an adjunct to the treatment armentarium of acute muscle ischemia in limbs and myocardium.
You reap what you sow! differences in knowledge exchange effectiveness between communication types
(2014)
FOR KNOWLEDGE-INTENSIVE ORGANIZATIONS IN THE FINANCE INDUSTRY, AN EFFECTIVE KNOWLEDGE EXCHANGE AMONG EMPLOYEES IS CRUCIAL FOR THE COMPETITIVE PERFORMANCE. THEREFORE, COMPANIES INCREASINGLY RELY ON SOCIAL MEDIA PLATFORMS TO FACILITATE COMMUNICATION AND COLLABORATION. TO ENHANCE OUR UNDERSTANDING OF SUCCESSFUL COMMUNICATION IN ENTERPRISE SOCIAL MEDIA, WE APPLY HUMAN CODING AND QUANTITATIVE ANALYSIS TO THE CONTENT AND TONE OF 15,505 ENTERPRISE MICROBLOGGING MESSAGES CREATED BY 1,166 EMPLOYEES OF AN INTERNATIONAL FINANCIAL SERVICE PROVIDER. OUR RESULTS SUGGEST THAT A MORE FACTUAL-ORIENTED COMMUNICATION TYPE BENEFITS FROM A HIGHER KNOWLEDGE EXCHANGE EFFECTIVENESS COMPARED TO A PRIMARILY SELF-DISCLOSING COMMUNICATION TYPE.
