Communicating and Visualising Urban Planning in Cold War Berlin
This article analyses the dynamics of communication, specifically with regard to the significance of visualisations in urban planning between the two competing political regimes of East and West Germany in divided Berlin (1945–1989). The article will demonstrate the ways in which planners on either side of the Iron Curtain were confronted with matters unique to their own political contexts and conditions for public communication, as well as how they faced similar challenges in fields of urban renewal and negotiating public participation. The post-war decades in Berlin were marked by strong planning dynamics: large-scale reconstruction after WWII and the ‘showcase character’ of political confrontation and competition. In this context, new strategies of communicating urban planning to the public were developed, such as large-scale development plans, public exhibitions and cross-border media campaigns. Paradigmatic shifts during the mid-1970s generated new discourses about urban renewal and historic preservation. The new focus on small-scale planning in vivid and inhabited inner-city neighbourhoods made new forms of communication and public depiction necessary. In the context of social and political change as well as growing mediatisation, planning authorities utilised aspects of urban identity and civic participation to legitimise planning activities. The article traces two small-scale planning projects for neighbourhoods in East and West Berlin and investigates the interrelation of visual communication instruments in public discourses and planning procedures during the 1980s, a period that prominently featured the new strategy of comprehensive planning. Furthermore, the article highlights the key role of micro-scale changes in the management of urban renewal along both sides of the wall and the emergence of neighbourhood civil engagement and participation
Strengthening participation through decentralisation: findings on local economic development in Kyrgyzstan
"Decentralisation and local government reform are important elements of many developing countries' efforts to improve state governance. Nonetheless, local governments often appear to be very limited in their ability to meet the high expectations associated with decentralisation and the introduction of local self-government. Kyrgyzstan in Central Asia is a typical example of a country where decentralisation efforts have been on the political agenda for more than a decade but actual results are less than satisfactory. While there is widespread agreement among experts about the diagnosis as such, so far little research has been done on the exact reasons for this situation and their effects on the Kyrgyz Republic's development potential. To address this question, this study analyses one particular aspect of decentralisation in the Kyrgyz Republic, namely its impact on popular participation in the design and implementation of local economic development policies. Proceeding from this analysis, the study derives conclusions and recommendations for the Kyrgyz government and other official bodies, local NGOs and international donors." (author's abstract
Predicting Major Adverse Events in Patients With Acute Myocardial Infarction
Early and accurate detection of short-term major adverse cardiac events (MACE) in patients with suspected acute myocardial infarction (AMI) is an unmet clinical need.; The goal of this study was to test the hypothesis that adding clinical judgment and electrocardiogram findings to the European Society of Cardiology (ESC) high-sensitivity cardiac troponin (hs-cTn) measurement at presentation and after 1 h (ESC hs-cTn 0/1 h algorithm) would further improve its performance to predict MACE.; Patients presenting to an emergency department with suspected AMI were enrolled in a prospective, multicenter diagnostic study. The primary endpoint was MACE, including all-cause death, cardiac arrest, AMI, cardiogenic shock, sustained ventricular arrhythmia, and high-grade atrioventricular block within 30 days including index events. The secondary endpoint was MACE + unstable angina (UA) receiving early (≤24 h) revascularization.; Among 3,123 patients, the ESC hs-cTnT 0/1 h algorithm triaged significantly more patients toward rule-out compared with the extended algorithm (60%; 95% CI: 59% to 62% vs. 45%; 95% CI: 43% to 46%; p < 0.001), while maintaining similar 30-day MACE rates (0.6%; 95% CI: 0.3% to 1.1% vs. 0.4%; 95% CI: 0.1% to 0.9%; p = 0.429), resulting in a similar negative predictive value (99.4%; 95% CI: 98.9% to 99.6% vs. 99.6%; 95% CI: 99.2% to 99.8%; p = 0.097). The ESC hs-cTnT 0/1 h algorithm ruled-in fewer patients (16%; 95% CI: 14.9% to 17.5% vs. 26%; 95% CI: 24.2% to 27.2%; p < 0.001) compared with the extended algorithm, albeit with a higher positive predictive value (76.6%; 95% CI: 72.8% to 80.1% vs. 59%; 95% CI: 55.5% to 62.3%; p < 0.001). For 30-day MACE + UA, the ESC hs-cTnT 0/1 h algorithm had a higher positive predictive value for rule-in, whereas the extended algorithm had a higher negative predictive value for the rule-out. Similar findings emerged when using hs-cTnI.; The ESC hs-cTn 0/1 h algorithm better balanced efficacy and safety in the prediction of MACE, whereas the extended algorithm is the preferred option for the rule-out of 30-day MACE + UA.

Direct Comparison of the 0/1h and 0/3h Algorithms for Early Rule-Out of Acute Myocardial Infarction
Innate activation of human primary epithelial cells broadens the host response to Mycobacterium tuberculosis in the airways
Early events in the human airways determining whether exposure to Mycobacterium tuberculosis (Mtb) results in acquisition of infection are poorly understood. Epithelial cells are the dominant cell type in the lungs, but little is known about their role in tuberculosis. We hypothesised that human primary airway epithelial cells are part of the first line of defense against Mtb-infection and contribute to the protective host response in the human respiratory tract. We modelled these early airway-interactions with human primary bronchial epithelial cells (PBECs) and alveolar macrophages. By combining in vitro infection and transwell co-culture models with a global transcriptomic approach, we identified PBECs to be inert to direct Mtb-infection, yet to be potent responders within an Mtb-activated immune network, mediated by IL1β and type I interferon (IFN). Activation of PBECs by Mtb-infected alveolar macrophages and monocytes increased expression of known and novel antimycobacterial peptides, defensins and S100-family members and epithelial-myeloid interactions further shaped the immunological environment during Mtb-infection by promoting neutrophil influx. This is the first in depth analysis of the primary epithelial response to infection and offers new insights into their emerging role in tuberculosis through complementing and amplifying responses to Mtb
Efficiency developments at European North Range container terminals
Container ports are critical nodes in global production networks and their ability to enhance efficiencies within supply chains and to extract value from them has become a competitive factor. Several performance measurement tools have been developed and frequently applied to measure the efficiency of container ports or container terminals and identify further improvement initiatives. Based on a number of advantages favouring its application to a complex seaport system, the non-parametric Data Envelopment Analysis (DEA) method has evolved into a preferred tool in academia. DEA enables efficiency measurement of container terminals in different geographical regions although its capabilities have not been applied solely to one special region with anticipated significant growth potential in a competitive environment: the European North Range. In addition, analysis of the efficiency development of North Range container terminals over time is seen as offering valuable insights for further improvement decisions. Thus, the main aim of this contribution is to analyse efficiency developments at 24 European North Range container terminals over a 5-year period from 2006 to 2010 with DEA. Furthermore, terminals are compared by their throughput ranking and operating system. Finally, the relevance of measures to improve efficiency at the terminal level is discussed and possibilities for future research are highlighted
A central CRMP complex essential for invasion in Toxoplasma gondii.
Apicomplexa are obligate intracellular parasites. While most species are restricted to specific hosts and cell types, Toxoplasma gondii can invade every nucleated cell derived from warm-blooded animals. This broad host range suggests that this parasite can recognize multiple host cell ligands or structures, leading to the activation of a central protein complex, which should be conserved in all apicomplexans. During invasion, the unique secretory organelles (micronemes and rhoptries) are sequentially released and several micronemal proteins have been suggested to be required for host cell recognition and invasion. However, to date, only few micronemal proteins have been demonstrated to be essential for invasion, suggesting functional redundancy that might allow such a broad host range. Cysteine Repeat Modular Proteins (CRMPs) are a family of apicomplexan-specific proteins. In T. gondii, two CRMPs are present in the genome, CRMPA (TGGT1_261080) and CRMPB (TGGT1_292020). Here, we demonstrate that both proteins form a complex that contains the additional proteins MIC15 and the thrombospondin type 1 domain-containing protein (TSP1). Disruption of this complex results in a block of rhoptry secretion and parasites being unable to invade the host cell. In conclusion, this complex is a central invasion complex conserved in all apicomplexans
