Data Gaps in Evidence-Based Research on Small Water Enterprises in Developing Countries

This paper assess the literature on small water enterprises -- water delivery operations that predominantly provide water at the community level. A research agenda is recommended to advance knowledge on effective SWE service

Local Public Services in Wisconsin: Alternatives for Municipalities with a Focus on Privatization

Both rural and urban municipal officials, faced with increased local resistance to higher taxes, increasing expenditure needs, weakening financial support from higher levels of government, and the growing pressure to "do more with less" have accelerated their search for alternative ways of delivering local public services. The downsizing of government has been brought to the forefront of public discussion in part due to the general conservative shift at the federal and state level and the need to maintain a balanced budget at the local level. Related private sector trends downsizing middle management as a means to become "leaner and meaner," reducing duplication and waste, and increasing earnings, profit levels, and returns to investors. At the same time many local public officials are faced with rising costs to maintain an aging infrastructure, accommodating the needs of special populations, satisfying rules and regulations imposed by higher levels of government, funding new investments to meet the demands of a growing economy in some instances, or maintaining critical services in the face declining economies. In short, the rules of the game for effective management of local governments have changed.

Rail transit fare collection: Policy and technology assessment

The impact of fare policies and fare structure on the selection of equipment was investigated, fare collection systems are described, hardware and technology related problems are documented, and the requirements of a fare collection simulation model are outlined. Major findings include: (1) a wide variation in the fare collection systems and equipment, caused primarily by historical precedence; (2) the reliability of AFC equipment used at BART and WMATA discouraged other properties from considering use of similar equipment; (3) existing equipment may not meet the fare collection needs of properties in the near future; (4) the cost of fare collection operation and maintenance is high; and (5) the relatively small market in fare collection equipment discourages new product development by suppliers. Recommendations for fare collection R&D programs include development of new hardware to meet rail transit needs, study of impacts of alternate fare policies increased communication among policymakers, and consensus on fare policy issues

Fiber optic control system integration

A total fiber optic, integrated propulsion/flight control system concept for advanced fighter aircraft is presented. Fiber optic technology pertaining to this system is identified and evaluated for application readiness. A fiber optic sensor vendor survey was completed, and the results are reported. The advantages of centralized/direct architecture are reviewed, and the concept of the protocol branch is explained. Preliminary protocol branch selections are made based on the F-18/F404 application. Concepts for new optical tools are described. Development plans for the optical technology and the described system are included

In situ sensors for measurements in the global trosposphere

Current techniques available for the in situ measurement of ambient trace gas species, particulate composition, and particulate size distribution are reviewed. The operational specifications of the various techniques are described. Most of the techniques described are those that have been used in airborne applications or show promise of being adaptable to airborne applications. Some of the instruments described are specialty items that are not commercially-available. In situ measurement techniques for several meteorological parameters important in the study of the distribution and transport of ambient air pollutants are discussed. Some remote measurement techniques for meteorological parameters are also discussed. State-of-the-art measurement capabilities are compared with a list of capabilities and specifications desired by NASA for ambient measurements in the global troposphere

MSUO Information Technology and Geographical Information Systems: Common Protocols & Procedures. Report to the Marine Safety Umbrella Operation

The Marine Safety Umbrella Operation (MSUO) facilitates the cooperation between Interreg funded Marine Safety Projects and maritime stakeholders. The main aim of MSUO is to permit efficient operation of new projects through Project Cooperation Initiatives, these include the review of the common protocols and procedures for Information Technology (IT) and Geographical Information Systems (GIS). This study carried out by CSA Group and the National Centre for Geocomputation (NCG) reviews current spatial information standards in Europe and the data management methodologies associated with different marine safety projects. International best practice was reviewed based on the combined experience of spatial data research at NCG and initiatives in the US, Canada and the UK relating to marine security service information and acquisition and integration of large marine datasets for ocean management purposes. This report identifies the most appropriate international data management practices that could be adopted for future MSUO projects

Methodology for urban rail and construction technology research and development planning

A series of transit system visits, organized by the American Public Transit Association (APTA), was conducted in which the system operators identified the most pressing development needs. These varied by property and were reformulated into a series of potential projects. To assist in the evaluation, a data base useful for estimating the present capital and operating costs of various transit system elements was generated from published data. An evaluation model was developed which considered the rate of deployment of the research and development project, potential benefits, development time and cost. An outline of an evaluation methodology that considered benefits other than capital and operating cost savings was also presented. During the course of the study, five candidate projects were selected for detailed investigation; (1) air comfort systems; (2) solid state auxiliary power conditioners; (3) door systems; (4) escalators; and (5) fare collection systems. Application of the evaluation model to these five examples showed the usefulness of modeling deployment rates and indicated a need to increase the scope of the model to quantitatively consider reliability impacts

Understanding Resilience and Evolution of IOIS in the Australian Pharmaceutical Distribution Industry

We analyse an empirical case study of an inter-organizational information system (IOIS) in the Australian pharmaceutical distribution industry, using a theoretical data coding approach, to provide a concise grounded account of changes in the material, normative and ideational structures within the participating practices over a 25 year period as the IOIS evolved from a proprietary closed system to a quasi-open shared ordering platform. We find evidence that the resilience of the IOIS over this long time period is explained by a layered accumulation of new structures at the level of individual practices, while the punctuated evolutionary change accompanied the appearance of a new practice, historically connected to the incumbent practices. These findings are in substantial agreement with systems evolution mechanisms proposed by Porra (1999). Understanding IOIS evolution will be important for the provision of key enabling information infrastructures envisioned in existing and planned ICT-mediated healthcare initiatives

Practices for strategic capacity management in Malaysian manufacturing firms

While the notion of manufacturing capabilities is a long-standing notion in research on operations management, its actual implementation and management has been hardly researched. Five case studies in Malaysia offered the opportunity to examine the practice of manufacturing managers with regard to strategic capability management. The data collection and analysis was structured by using the notion of Strategic Capacity Management. Whereas traditionally literature has demonstrated the beneficial impact of an appropriate manufacturing strategy on the business strategy and performance, the study highlights the difficulty of managers to set the strategy, let alone implementing it. This is partly caused by the immense pressure of customers in these dominantly Make-To-Order environments for SMEs. Current concepts for manufacturing capabilities have insufficiently accounted this phenomenon and an outline of a research agenda is presented
