THE USD 1875.95 SEED CENTER

Built on the world's largest floodplain, Bangladesh is a country under immediate threat of climate change. This project works with two impoverished and rural communities in western Bangladesh by equipping them with a cost-efficient means for disaster resilience and agricultural biodiversity. By constructing local community seed centers, each community can implement a new system of seed banking, agricultural education, and women's rights as a means to defend against increased flood rates, droughts, and crop failure. Local and wild seed varieties are championed over government seeds as a means for agricultural bio-security and to ensure the stability of community needs in the face of unstable government assistance programs. The USD 1,875.95 Seed Center continues to push the ability of landscape architecture to perform with communities as a tool of social and economic improvement and development in the face of climate change at the micro-scale.

Community-based programs to promote car seat restraints in children 0-16 years -- a systematic review

STUDY OBJECTIVE: Community-based models for injury prevention have become an accepted part of the overall injury control strategy. This systematic review of the scientific literature examines the evidence for their effectiveness in reducing injury due to inadequate car seat restraint use in children 0-16 years of age. METHODS: A comprehensive search of the literature was performed using the following study selection criteria: community-based intervention study; target population was children aged 0-16 years of age; outcome measure was either injury rates due to motor vehicle crashes or observed changes in child restraint use; and use of community control or historical control in the study design. Quality assessment and data abstraction was guided by a standardized procedure and performed independently by two authors. Data synthesis was in tabular and text form with meta-analysis not being possible due to the discrepancy in methods and measures between the studies. RESULTS: This review found eight studies, that met all the inclusion criteria. In the studies that measured injury outcomes, significant reductions in risk of motor vehicle occupant injury (33-55%) were reported in the study communities. For those studies reporting observed car seat restraint use the community-based programs were successful in increasing toddler restraint use in 1-5 year aged children by up to 11%; child booster seat use in 4-8 year aged children by up to 13%; rear restraint use in children aged 0-15 years by 8%; a 50% increase in restraint use in pre-school aged children in a high-risk community; and a 44% increase in children aged 5-11 years. CONCLUSION: While this review highlights that there is some evidence to support the effectiveness of community-based programs to promote car restraint use and/or motor vehicle occupant injury, limitations in the evaluation methodologies of the studies requires the results to be interpreted with caution. There is clearly a need for further high quality program evaluation research to develop an evidence base.

Analysis of quality costs for identifying areas of quality improvement—a case study

This paper reports the results of a study carried out in one of the plants of a multi-plant manufacturer with the objective of evaluating and analysing the quality costs to identify areas of quality improvement and quality cost reduction. The study was carried out in two phases, namely the estimation of quality costs as a ‘one-shot’ study followed by the identification of the ‘vital few’ defects using Pareto analysis, and this was followed by a further analysis using cause-and-effect diagrams to find out the underlying causes of these vital defects. This case study shows that even in situations where inspection and relevant records/data are not available, the necessary data can be obtained through a step-by-step analysis of current procedure and methods, and collection of data with regard to defects; and the data, thus obtained, can be used for the evaluation of quality costs. Moreover, an objective analysis of category-wise and shop-wise quality costs, with the help of Pareto and cause-and-effect analyses can bring out the critical quality problems and subsequently the causes for these critical defects.
