Sharing individualized results with health study participants, a practice we and others refer to as “report-back,” ensures participant access to exposure and health information and may promote health equity. However, the practice of report-back and the content shared is often limited by the time-intensive process of personalizing reports. Software tools that automate creation of individualized reports have been built for specific studies, but are largely not open-source or broadly modifiable. We created an open-source and generalizable tool, called the Macro for the Compilation of Report-backs (MCR), to automate compilation of health study reports. We piloted MCR in two environmental exposure studies in Massachusetts, USA, and interviewed research team members (n = 7) about the impact of MCR on the report-back process. Researchers using MCR created more detailed reports than during manual report-back, including more individualized numerical, text, and graphical results. Using MCR, researchers saved time producing draft and final reports. Researchers also reported feeling more creative in the design process and more confident in report-back quality control. While MCR does not expedite the entire report-back process, we hope that this open-source tool reduces the barriers to personalizing health study reports, promotes more equitable access to individualized data, and advances self-determination among participants.

The open-source software (OSS) movement is often analogized as a commons, where products are developed by and consumed in an open community. However, does a larger commons automatically beget success or does the phenomenon fall prey to the tragedy of the commons? This research forwards and empirically investigates the curvilinear relationship between developers and OSS project quality and a project's download volume. Using segmented regression on over 12,000 SourceForge OSS projects, findings suggest an inflection point in the number of contributing developers on download volume – suggesting increasing and diminishing returns to scale from adding developers to OSS projects. Findings support the economic principle of the tragedy of the commons, a concept where an over-allocated (large number) of developers, even in an open-source environment, can lead to resource mismanagement and reduce the benefit of a public good, i.e. the OSS project.

Abstract Over the globe efforts are being made to collect data and develop an adequate water resource information system for optimising its use. India is the largest consumer of water with an estimated usage of around 300 cubic kilometers per year. Punjab, a north-western state of India, is an example of severe crises aquifer depletion due to unconstrained consumption of groundwater leads to degrade the quantity as well as quality of it. Thus it is of great importance to compile up to date information about the water requirement for its appropriate and sustainable use. Remote sensing and Geographic Information system (GIS) are the technologies that can provide efficient & effective information system to tackle the water quality & water supply planning parameters. Thus, under the present study, a web enabled water resource information system has been developed in GIS environment for the SAS (Sahibzada Ajit Singh) Nagar and Patiala districts of Punjab by using the open source software – MS4W and pmapper. This system provides digital information of natural i.e. drainage & man made features like roads, canals, tube well with its location etc., and also provide the information related to water level, water quality of wells, and well depth for the study area. Such an information system can be very helpful for the administrators and can serve as a decision support system for the planners and policy makers so that the areas where the problem related to water quality can be identified and focused upon. The system can provide an effective and meaningful direction for the planning and development of both districts.

In the field of multimedia, very little attention is given to the activities involved in the preservation of audio documents. At the same time, more and more archives storing audio and video documents face the problem of obsolescing and degrading media, which could largely benefit from the instruments and the methodologies of research in multimedia. This paper presents the methodology and the results of the Italian project REVIVAL, aimed at the development of a hardware/software platform to support the active preservation of the audio collection of the Fondazione Arena di Verona, one of the finest in Europe for the operatic genre, with a special attention on protocols and tools for quality control. On the scientific side, the most significant objectives achieved by the project are (i) the setup of a working environment inside the archive, (ii) the knowledge transfer to the archival personnel, (iii) the realization of chemical analyses on magnetic tapes in collaboration with experts in the fields of materials science and chemistry, and (iv) the development of original open-source software tools. On the cultural side, the recovery, the safeguard, and the access to unique copies of unpublished live recordings of artists the calibre of Domingo and Pavarotti are of great musicological and economical value.

Online and realtime monitoring system for water quality that uses a computer mainboard as data logger requires software applications that serve to control the sensor work in order to measure the water quality data and sends it to the data center. Some of the requirements such as data measurement, storage and delivery of data and early warning system are required by the data logger in order to have the features as desired by the majority of users of this system. To facilitate the making of the program code, sensor with serial communication ports (RS232C) will be used. Program control data logger that meets these requirements is developed using Water Flow Software Development Life Cycle method and using GNU C++ the free open source software (FOSS) as the development tools. Program control data logger that has been developed will be installed to the data logger hardware and operated using FreeBSD as the Operating system. The program will run on the class 10 of flash drive with 16 giga byte capacity. Keywords: water quality monitoring, online/realtime monitoring, early warning system (EWS), open source software, data logger, onlimo OSS, control data logger, GNU C++

Real-time water quality monitoring requires data logger for automatic data retrieval  by sensors. The hardware data logger for realtime monitoring can be developed by utilizing scars computer mainboard that are still functioning and widely avaliable in the market at low prices. Through online monitoring applications that developed by using free open source software, water quality data can be measured in accordance with the specified time interval and stored in the database system. This paper discusses the hardware selection and recomendation studies that include the motherboard and CPU, storage, transmission and communication medium required for the manufacturing of computer's mainboard based data logger. The results of this study are to be used as an alternative data logger selection for realtime water quality monitoring with low investment costs. So, the water companies can monitor raw water quality from their water treatment plant as well as the industrial can monitor wastewater quality from wastewater treatment plant. Keyword : online monitoring, real time monitoring, early warning system (EWS), open source software, data logger, onlimo OSS.

Over the last two decades, advancements in analytical cartography have reduced the need for professional geomatics experts when creating maps. GIS software have greatly simplified the map creation process, allowing non-experts to make maps using many built-in tools. However, this has resulted in a lack of quality control and assessment when data is manipulated and processed towards developing maps. This also raises questions with regards to reliability, validity and objectivity of data, results and maps. In contrast, this paper presents a methodology for automating both the GIS analysis and Map Making processes using analytical cartography in a non-standard GIS environment. The work was done primarily in the R environment, open source software and programming, to replicate processes that were normally done using expensive proprietary software and many person hours. Applied in a case study to improve the workflow efficiency in precipitation index modelling, the developed system was found to improve on overall time by tenfold, the formats and number of products generated were more than doubled, the replicability of map layouts was greatly improved, and the published formats increased.
