Web-based data collection is increasingly popular in both experimental and survey-based research, because it is flexible, efficient and location-independent. While dedicated software for laboratory-based experimentation and online surveys is commonplace, researchers looking to implement experiments in the browser have, heretofore, often had to manually construct their studies’ content and logic using code. We introduce lab.js, a free, open-source experiment builder that makes it easy to build experiments for both online and in-laboratory data collection. Through its visual interface, stimuli can be designed and combined into a study without programming, though studies’ appearance and behavior can be fully customized using HTML, CSS and JavaScript code if required. Presentation and response times are kept and measured with high accuracy and precision heretofore unmatched in browser-based studies. Experiments constructed with lab.js can be run directly on a local computer, and published online with ease, with direct deployment to cloud hosting, export to any web server, and integration with popular data collection tools. Studies can also be shared in an editable format, archived, re-used and adapted, enabling effortless, transparent replications, and thus facilitating open, cumulative science. The software is provided free of charge under an open-source license; further information, code and extensive documentation are available from https://lab.js.org/.

ObjectiveAn intranet portal that combines cost-free, open-source software technology with easy set-up features can be beneficial for daily hospital processes. We describe the short-term adoption rates of a costless content management system (CMS) in the intranet of a tertiary Greek hospital.DesignDashboard statistics of our CMS platform were the implementation assessment of our system.ResultsIn a period of 10 months of running the software, the results indicate the employees overcame ‘Resistance to Change’ status. The average growth rate of end users who exploit the portal services is calculated as 2.73 every 3.3 months.ConclusionWe found our intranet web-based portal to be acceptable and helpful so far. Exploitation of an open-source CMS within the hospital intranet can influence healthcare management and the employees’ way of working as well.

The availability of water-related data and information across different geographical and jurisdictional scales is of critical importance for the conservation and management of water resources in the 21<sup>st</sup> century. Today information assets are often found fragmented across multiple agencies that use incompatible data formats and procedures for data collection, storage, maintenance, analysis, and distribution. The growing adoption of Web mapping systems in the water domain is reducing the gap between data availability and its practical use and accessibility. Nevertheless, more attention must be given to the design and development of these systems to achieve high levels of interoperability and usability while fulfilling different end user informational needs. This paper first presents a brief overview of technologies used in the water domain, and then presents three examples of Web mapping architectures based on free and open source software (FOSS) and the use of open specifications (OS) that address different users’ needs for data sharing, visualization, manipulation, scenario simulations, and map production. The purpose of the paper is to illustrate how the latest developments in OS for geospatial and water-related data collection, storage, and sharing, combined with the use of mature FOSS projects facilitate the creation of sophisticated interoperable Web-based information systems in the water domain.

lab.js Builder is free and open-source software that makes it easy to build experiments and surveys for both online and in-laboratory data collection. By using its visual interface, stimuli can be designed and integrated into experiments and surveys without programming, though it can be also customized using HTML, CSS, and JavaScript code. This software would be beneficial for many students and scientists to build and run their experiments and surveys under the situations of homeschooling and remote working. In this tutorial article, we introduce the functions of lab.js Builder and easy-to-use method for it, and also demonstrate the method of building and conducting the practical experiment at the class of the university.

Urban surroundings and spaces are losing their identity due to the flooded visual pollution in the urban panorama of already densely populated cities in developing countries. Quantitative assessment of visual pollution and its spatial mapping; both are very recent and relatively un-explored branches of urban studies. The diversity of visual pollution objects (VPOs) and their traits, the subjectivity of observers, the scale of urban space and dependency on subjective variables has been key challenges for quantification during visual pollution assessment. The researcher has previously developed a paper-based score-card type visual pollution assessment (VPA) tool using Analytical Hierarchy Process (under publication) to address these issues. However, considering the challenges associated with the deployment of paper-based tool for VPA (inability to handle variety of data types i.e. text, numeric, geolocation, images etc.), the natural progression has been the development of a mobile-based solution which matches the fast-growing mobile penetration rate of urban centers and provides a turn-key solution to achieve efficiency and effectiveness in primary data collection. On the other hand, academic research on the spatial mapping of visual pollution has slightly progressed to explore its cartographic dimension. This research presents a spatial decision support system comprising of a combination of open source tools to collect, store and present visual pollution assessment data for any urban space of any scale. The system employs Open Data Kit (ODK) to build its mobilebased VPA tool which can be used to collect VPO attributes using any android device. The collected data is streamed to a web-based data management module of the system in real time which is built upon ODK Aggregate and PostgreSQL. Furthermore, the web-based visualization module of the system is built upon some other major open source tools including OpenGeo Suite and PHP. The visualization module presents the results of visual pollution index (VPI) in the form of a web-based dashboard containing real-time choropleth maps which can be filtered for any specific VPO.This research demonstrates the strengths of open geospatial tools to solve challenges of primary data collection on a diverse range of VPOs along with the systematic capturing of their spatial location and visual images. Furthermore, it proves the ability of open source web mapping tools to display visual pollution assessments in most appropriate cartographic representation.

At Seton Hall University we developed Asset, a web-based Academic Survey System and Evaluation Tool to design, administer, and analyze surveys. This free, Open-Source project is widely used at our institution and has even been approved for electronic voting. Other universities have also successfully deployed the project. In this article we will introduce the Asset system, describe its design principles and capabilities, and compare it to similar tools. We will include a discussion of sample surveys using Asset and briefly describe the requirements for installing the system.

AbstractBackgroundWe present VREX, a free open-source Unity toolbox for virtual reality research in the fields of experimental psychology and neuroscience.ResultsDifferent study protocols about perception, attention, cognition and memory can be constructed using the toolbox. VREX provides a procedural generation of (interconnected) rooms that can be automatically furnished with a click of a button. VREX includes a menu system for creating and storing experiments with different stages. Researchers can combine different rooms and environments to perform end-to-end experiments including different testing situations and data collection. For fine-tuned control VREX also comes with an editor where all the objects in the virtual room can be manually placed and adjusted in the 3D world.ConclusionsVREX simplifies the generation and setup of complicated VR scenes and experiments for researchers. VREX can be downloaded and easily installed from vrex.mozello.com
