Stakeholder perspectives of pediatric powered wheelchair standing devices: a qualitative study.

Aim: To explore and describe the experiences and perspectives of various stakeholders regarding the use of powered wheelchair standing devices (PWSDs).

Method: The purposive sample included: children aged 6 to 18 years who used a PWSD (n=8; diagnoses: cerebral palsy, spinal muscular atrophy, spina bifida, spinal cord injury), parents of children 18 years of age or younger who used a PWSD (n=12), rehabilitation professionals working with children who used a PWSD (n=12), and professionals working at companies manufacturing PWSDs (n=3). Data were gathered via face-to-face interviews conducted either in person or via Zoom and analyzed using the constant comparative method.

Regaining momentum for international climate policy beyond Copenhagen.

The 'Copenhagen Accord' fails to deliver the political framework for a fair, ambitious and legally-binding international climate agreement beyond 2012. The current climate policy regime dynamics are insufficient to reflect the realities of topical complexity, actor coalitions, as well as financial, legal and institutional challenges in the light of extreme time constraints to avoid 'dangerous' climate change of more than 2 degrees C. In this paper we analyze these stumbling blocks for international climate policy and discuss alternatives in order to regain momentum for future negotiations.

On fair, effective and efficient REDD mechanism design.

The issues surrounding 'Reduced Emissions from Deforestation and Forest Degradation' (REDD) have become a major component of continuing negotiations under the United Nations Framework Convention on Climate Change (UNFCCC). This paper aims to address two key requirements of any potential REDD mechanism: first, the generation of measurable, reportable and verifiable (MRV) REDD credits; and secondly, the sustainable and efficient provision of emission reductions under a robust financing regime.To ensure the supply of MRV credits, we advocate the establishment of an 'International Emission Reference Scenario Coordination Centre' (IERSCC).

Development of automated high-throughput ecotoxicity and genotoxicity test systems and fields of application.

Bioassays like growth inhibition and genotoxicity assays are frequently used for the characterization of chemicals and contaminated environmental samples. In this work two standardized bioassays are automated completely using newly developed liquid handling stations and robotics. A high-throughput algal growth inhibition assay prototype is set up and optimized in cooperation with Hoelle & Huettner AG (Tuebingen, Germany) and Polygen GmbH (Langen, Germany).

Attention deficit disorder without hyperactivity: a distinct behavioral and neurocognitive syndrome.

This study examined the issue as to whether or not children carefully diagnosed as having either attention deficit disorder with hyperactivity (ADDH) or without hyperactivity (ADDnoH) could be distinguished on selected cognitive, academic, rapid naming, and behavioral measures. Employing a previously validated multimodal, multi-informant diagnostic process that results in reliable clinical diagnoses, 10 ADDH and 10 ADDnoH children were examined. While no significant differences in cognitive ability were noted between groups, significant underachievement was found in the children diagnosed as ADDnoH, particularly in mathematics achievement.

Regional cerebral blood flow (rCBF) in normal readers: bilateral activation with narrative text.

Based on recent evidence that suggests a more active participation of the right cerebral hemisphere in reading, this exploratory study examined changes in regional cerebral blood flow (rCBF) in three normal subjects during the reading of controlled narrative text. Narrative text presumably activates all neurocognitive processes important in reading including the semantic, pragmatic, emotional, and imagery components. Because of the small number of subjects, percentage change over a baseline at rest condition in rCBF during reading was compared to test/retest variability in control subjects.
