Cross-Location Analysis of the Impact of Household Socioeconomic Status on Participation in Urban and Peri-Urban Agriculture in West Africa

This study explores the relation between household socioeconomic status (SES) and participation in urban and periurban agriculture (UPA) in three West African cities. We used a structured questionnaire to survey 700 randomly selected households: 250 in Kano, Nigeria, 250 in Bobo Dioulasso, Burkina Faso, and 200 in Sikasso, Mali. Multiple correspondence analysis was applied on household asset variables to create an index of assets which was used as a proxy for household SES. The results showed no significant differences in households’ rate of participation in UPA across socioeconomic groups. Participation in UPA was rather significantly (P < 0.001) and positively related to household size. Interestingly, the analysis revealed that field crop cultivation and gardening were more common among households in the low and medium SES groups while those in the high SES group were more likely to keep livestock

European consensus statement on diagnosis and treatment of adult ADHD: The European Network Adult ADHD.

BACKGROUND: Attention deficit hyperactivity disorder (ADHD) is among the most common psychiatric disorders of childhood that persists into adulthood in the majority of cases. The evidence on persistence poses several difficulties for adult psychiatry considering the lack of expertise for diagnostic assessment, limited treatment options and patient facilities across Europe. METHODS: The European Network Adult ADHD, founded in 2003, aims to increase awareness of this disorder and improve knowledge and patient care for adults with ADHD across Europe. This Consensus Statement is one of the actions taken by the European Network Adult ADHD in order to support the clinician with research evidence and clinical experience from 18 European countries in which ADHD in adults is recognised and treated. RESULTS: Besides information on the genetics and neurobiology of ADHD, three major questions are addressed in this statement: (1) What is the clinical picture of ADHD in adults? (2) How can ADHD in adults be properly diagnosed? (3) How should ADHD in adults be effectively treated? CONCLUSIONS: ADHD often presents as an impairing lifelong condition in adults, yet it is currently underdiagnosed and treated in many European countries, leading to ineffective treatment and higher costs of illness. Expertise in diagnostic assessment and treatment of ADHD in adults must increase in psychiatry. Instruments for screening and diagnosis of ADHD in adults are available and appropriate treatments exist, although more research is needed in this age group

Evaluatie sleutelprojecten: Onderzoek in opdracht van het Ministerie van VROM

In de Structuurvisie Randstad 2040 kondigt het kabinet aan om een verkenning te overwegen naar Randstad-sleutelprojecten voor de periode na 2020. Voorafgaand aan het besluit om een dergelijke verkenning daadwerkelijk te starten, wordt een evaluatieonderzoek uitgevoerd naar de eerste generatie- en tweede generatie sleutelprojecten. Een aantal daarvan is afgerond, maar de meeste zijn nog in de realisatiefase. Evaluatie van de mate van doelbereiking, de effectiviteit, de doelmatigheid en de bestuurlijke effecten van deze sleutelprojecten moet bijdragen aan de besluitvorming door het kabinet. Dit rapport doet verslag van de evaluatie van sleutelprojecten.Urban studiesOTB Research Institut

Towards automation of control software:a review of challenges in mechatronic design

Development of mechatronic systems requires collaboration among experts from different design domains. In this paper the authors identify a set of challenges related to the design of mechatronic systems. The challenges are mostly related to integration of design and analysis tools, and automation of current design practices. Addressing these challenges enables the adoption of a concurrent development approach in which the synergetic effects that characterize mechatronic systems are taken into account during design. The main argument is that in order to deal with software development problems for complex mechatronic systems, there is a need to look at system design practices beyond concurrency, i.e., there is a need to consider the complex interdependencies among subsystems and the designers that develop them. A review on current methods and tools is carried out to identify possible solutions proposed in previous works. The purpose is not to make an extensive review, but to show that integration, from different points of view, is a major issue and that increasing the level of abstraction in the description of systems can help to overcome the integration challenges. An increased level of abstraction also forms a basis for addressing other issues in mechatronic product development, which are presented in this work. With that in mind, concepts for an integration framework are proposed. The goal of the framework is to support a multi-disciplinary design team to (almost) automatically generate and verify control software. Based on high-level architectural descriptions, the software generation and verification process can be supported by knowledge-based methods and tools. Other goals are to support communication among engineers, improve reliability of designs, increase reuse of design knowledge, and reduce development time and development costs
