Multidecadal variability of summer temperature over Romania and its relation with Atlantic Multidecadal Oscillation

We investigate the multidecadal variability of summer temperature over Romania as measured at 14 meteorological stations with long term observational records. The dominant pattern of summer temperature variability has a monopolar structure and shows pronounced multidecadal variations. A correlation analysis reveals that these multidecadal variations are related with multidecadal variations in the frequency of four daily atmospheric circulation patterns from the North Atlantic region. It is found that, on multidecadal time scales, negative summer mean temperature (TT) anomalies are associated with positive sea level pressure (SLP) anomalies centered over the northern part of the Atlantic Ocean and Scandinavia and negative SLP anomalies centered over the northern part of Africa. It is speculated that a possible cause of multidecadal fluctuations in the frequency of these four patterns are the sea surface temperature anomalies associated to the Atlantic Multidecadal Oscillation. These results have implications for predicting the evolution of summer temperature over Romania on multidecadal time scales

Comparative Genomics Analysis of Streptococcus Isolates from the Human Small Intestine Reveals their Adaptation to a Highly Dynamic Ecosystem

Contains fulltext : 125564.pdf (publisher's version ) (Open Access)The human small-intestinal microbiota is characterised by relatively large and dynamic Streptococcus populations. In this study, genome sequences of small-intestinal streptococci from S. mitis, S. bovis, and S. salivarius species-groups were determined and compared with those from 58 Streptococcus strains in public databases. The Streptococcus pangenome consists of 12,403 orthologous groups of which 574 are shared among all sequenced streptococci and are defined as the Streptococcus core genome. Genome mining of the small-intestinal streptococci focused on functions playing an important role in the interaction of these streptococci in the small-intestinal ecosystem, including natural competence and nutrient-transport and metabolism. Analysis of the small-intestinal Streptococcus genomes predicts a high capacity to synthesize amino acids and various vitamins as well as substantial divergence in their carbohydrate transport and metabolic capacities, which is in agreement with observed physiological differences between these Streptococcus strains. Gene-specific PCR-strategies enabled evaluation of conservation of Streptococcus populations in intestinal samples from different human individuals, revealing that the S. salivarius strains were frequently detected in the small-intestine microbiota, supporting the representative value of the genomes provided in this study. Finally, the Streptococcus genomes allow prediction of the effect of dietary substances on Streptococcus population dynamics in the human small-intestine

Interagency Relations and the {EU} Migration Crisis: Strengthening of Law Enforcement Through Agencification?

While scholarly literature on Frontex has mushroomed over the last decade, agency’s interaction with other EU Justice and Home Affairs (JHA) agencies has received less attention. It is the objective of this paper to analyse how the crisis has shaped the horizontal interactions between EU JHA agencies and ask whether these relations have either enhanced the law enforcement focus of EU JHA or, conversely, strengthened a human rights-promoting EU as a ‘Union of Values’. Empirically, the chapter assesses the relations of Frontex with other JHA-related agencies such as the European Asylum Support Office or the Fundamental Rights Agency before and after the 2015 migration crisis. We argue that despite an increased human rights sensitivity, the migration crisis has not substantially changed the border management approach of Frontex but rather consolidated law enforcement profile of interagency cooperation and led only to minor improvements of fundamental rights

Blame, Reputation, and Organizational Responses to a Politicized Climate

Hinterleitner and Sager conceptualize how public sector organizations (PSOs) react to elite polarization, which is as an increasingly common phenomenon in Western democracies. For politicians operating under polarized conditions, PSOs are a primary blame-deflection target. Since blame from politicians presents a threat to the reputation of PSOs, they react to these threats. While research has made progress in examining specific responses to reputational threats, the authors argue that an overarching categorization of responses is missing. The chapter adapts the concept of anticipatory blame avoidance to the decision-making of PSOs, using it as an umbrella concept to categorize and systematize the reactions of PSOs. PSOs that prioritize crafting responses to reputational threats may neglect tasks and duties potentially decisive for effective and problem-oriented public service delivery
