Mine Injury Casualties Report from the Iraq-Kuwait DMZ

After the implementation of the UN Iraq-Kuwait Observation Mission (UNIKOM) at the end of the first Gulf War in 1990, a medical team was set up in 1991 to support the UN troops in their difficult tasks in the demilitarised zone (DMZ), a remote desert area between Kuwait and Iraq. The medical team was designed to take care of the medical treatment for the UNIKOM members and the nomadic people living in the DMZ as pointed out in UN Secretary-General reports S/2001/287 and S/2001/913 on the official UN website

Considerations of Efficiency and Distributive Justice in Multidimensional Poverty Measurement

Ab den 1980er Jahren entwickelte Amartya Sen eine neue Wohlfahrtstheorie: den Capability Approach (Sen, 1979; 1985; 1992; 1999; 2009). Dabei ersetzen Capabilities und Functionings, d.h. das, was Personen tatsächlich in der Lage sind zu tun und zu sein, den traditionellen Einkommensansatz. Armut ist im Capability Approach das Unvermögen, ein bestimmtes Minimum an zentralen Capabilities zu erreichen, die benötigt werden, um das Leben nach den eigenen Vorstellungen zu gestalten. Der Capability Approach hat so viele interessante Eigenschaften, besonders in Bezug auf die Armutsmessung, dass er zunehmend Einfluss in der Wohlfahrtsökonomie gewinnt. Diese Entwicklung wird durch empirische Untersuchungen gefördert, die zeigen, dass dieser multidimensionale Ansatz zur Armutsmessung deutlich andere Ergebnisse generiert als der traditionelle Einkommensansatz (vgl. Klasen, 2000, Alkire und Santos, 2010, Figari, 2012). Der derzeitige multidimensionale Ansatz hat jedoch eine methodische Schwäche: Ungleichheit zwischen Armutsdimensionen wird entweder als Korrelationssensitivität definiert – womit Effizienz aber nicht Verteilungsgerechtigkeit berücksichtigt wird – oder als die Verteilung multipler Mangelerscheinungen in einer Gesellschaft – womit Verteilungsgerechtigkeit aber nicht Effizienz berücksichtigt wird. Die ersten beiden Kapitel dieser Dissertation widmen sich der Behebung dieser methodischen Schwäche. Dazu wird Ungleichheit zwischen Dimensionen zunächst als „korrelationssensitive Verteilung multipler Mangelerscheinungen in einer Gesellschaft“ definiert. Die ersten beiden Kapitel operationalisieren diese erweiterte Definition für den Fall ordinaler und kardinaler Armutsindices. Im Einzelnen wird ein neues Axiom für den ordinalen sowie den kardinalen Fall eingeführt, das das Ausmaß, mit dem ein Ungleichheitsfördernder Tausch Armut sinken (oder steigen) lässt, von der Beziehung zwischen den Armutsdimensionen abhängig macht. Diese Neuerung wird benutzt um eine neue Klasse ordinaler bzw. kardinaler Armutsindices herzuleiten. Diese zwei Klassen sind die ersten additiven Armutsindices die in der Lage sind, sowohl Ungleichheit als auch Korrelationssensitivität zu erfassen. Das dritte Kapitel nutzt das deutsche sozio-ökonomische Panel um zwei ordinale Armutsindices für Deutschland vorzuschlagen, die auf der zuvor entwickelten Methode basieren: den „Deutschen Korrelationssensitiven Armutsindex“ und den „Subjektiven Korrelationssensitiven Armutsindex“. Die beiden Indices werden mit dem offiziellen deutschen Armutsmaß, der Armutsgefährdungsquote, über Dimensionen, Regionen und über die Zeit hinweg verglichen. Die Resultate zeigen vor allem eines: die signifikanten Unterschiede in der Beurteilung von Armut und Armutstrends die durch die verschiedenen Indices versursacht werden und den hohen Mehrwert den die Operationalisierung des Capability Approachs darstellt

Connections to the Electrodes Control the Transport Mechanism in Single-Molecule Transistors.

When designing a molecular electronic device for a specific function, it is necessary to control whether the charge-transport mechanism is phase-coherent transmission or particle-like hopping. Here we report a systematic study of charge transport through single zinc-porphyrin molecules embedded in graphene nanogaps to form transistors, and show that the transport mechanism depends on the chemistry of the molecule-electrode interfaces. We show that van der Waals interactions between molecular anchoring groups and graphene yield transport characteristic of Coulomb blockade with incoherent sequential hopping, whereas covalent molecule-electrode amide bonds give intermediately or strongly coupled single-molecule devices that display coherent transmission. These findings demonstrate the importance of interfacial engineering in molecular electronic circuits

Efficacy and safety of rozanolixizumab in moderate to severe generalized myasthenia gravis : a phase 2 randomized control trial

OBJECTIVE: To explore the clinical efficacy and safety of subcutaneous (SC) rozanolixizumab, an anti-neonatal Fc receptor humanized monoclonal antibody, in patients with generalized myasthenia gravis (gMG). METHODS: In this phase 2a, randomized, double-blind, placebo-controlled, 2-period, multicenter trial (NCT03052751), patients were randomized (1:1) in period 1 (days 1-29) to 3 once-weekly (Q1W) SC infusions of rozanolixizumab 7 mg/kg or placebo. In period 2 (days 29-43), patients were re-randomized to either rozanolixizumab 7 mg/kg or 4 mg/kg (3 Q1W SC infusions), followed by an observation period (days 44-99). Primary endpoint was change from baseline to day 29 in Quantitative Myasthenia Gravis (QMG) score. Secondary endpoints were change from baseline to day 29 in MG-Activities of Daily Living (MG-ADL) and MG-Composite (MGC) scores and safety. RESULTS: Forty-three patients were randomized (rozanolixizumab 21, placebo 22 [period 1]). Least squares (LS) mean change from baseline to day 29 for rozanolixizumab vs placebo was as follows: QMG (LS mean -1.8 vs -1.2, difference -0.7, 95% upper confidence limit [UCL] 0.8; p = 0.221; not statistically significant), MG-ADL (LS mean -1.8 vs -0.4, difference -1.4, 95% UCL -0.4), and MGC (LS mean -3.1 vs -1.2, difference -1.8, 95% UCL 0.4) scores. Efficacy measures continued to improve with rozanolixizumab 7 mg/kg in period 2. The most common adverse event in period 1 was headache (rozanolixizumab 57%, placebo 14%). CONCLUSION: Whereas change from baseline in QMG was not statistically significant, the data overall suggest rozanolixizumab may provide clinical benefit in patients with gMG and was generally well tolerated. Phase 3 evaluation is ongoing (NCT03971422). CLASSIFICATION OF EVIDENCE: This study provides Class I evidence that for patients with gMG, rozanolixizumab is well-tolerated, but did not significantly improve QMG score

Detection of child abuse in emergency departments: a multi-centre study

Objective: This study examines the detection rates of suspected child abuse in the emergency departments of seven Dutch hospitals complying and not complying with screening guidelines for child abuse. Design: Data on demographics, diagnosis and suspected child abuse were collected for all children aged ≤18 years who visited the emergency departments over a 6-month period. The completion of a checklist of warning signs of child abuse in at least 10% of the emergency department visits was considered to be compliance with screening guidelines. Results: A total of 24 472 visits were analysed, 54% of which took place in an emergency department complying with screening guidelines. Child abuse was suspected in 52 children (0.2%). In 40 (77%) of these 52 cases, a checklist of warning signs had been completed compared with a completion rate of 19% in the total sample. In hospitals complying with screening guidelines for child abuse, the detection rate was higher (0.3%) than in those not complying (0.1%, p<0.001). Conclusion: During a 6-month period, emergency department staff suspected child abuse in 0.2% of all children visiting the emergency department of seven Dutch hospitals. The numbers of suspected abuse cases detected were low, but an increase is likely if uniform screening guidelines are widely implemented

Molecular evolution of HoxA13 and the multiple origins of limbless morphologies in amphibians and reptiles

Developmental processes and their results, morphological characters, are inherited through transmission of genes regulating development. While there is ample evidence that cis-regulatory elements tend to be modular, with sequence segments dedicated to different roles, the situation for proteins is less clear, being particularly complex for transcription factors with multiple functions. Some motifs mediating protein-protein interactions may be exclusive to particular developmental roles, but it is also possible that motifs are mostly shared among different processes. Here we focus on HoxA13, a protein essential for limb development. We asked whether the HoxA13 amino acid sequence evolved similarly in three limbless clades: Gymnophiona, Amphisbaenia and Serpentes. We explored variation in ω (dN/dS) using a maximum-likelihood framework and HoxA13sequences from 47 species. Comparisons of evolutionary models provided low ω global values and no evidence that HoxA13 experienced relaxed selection in limbless clades. Branch-site models failed to detect evidence for positive selection acting on any site along branches of Amphisbaena and Gymnophiona, while three sites were identified in Serpentes. Examination of alignments did not reveal consistent sequence differences between limbed and limbless species. We conclude that HoxA13 has no modules exclusive to limb development, which may be explained by its involvement in multiple developmental processes
