Event-driven reactive functionalities are urgently needed in present-day distributed systems and dynamic Web-based environments. Reaction rules constitute a promising approach to specify and program such reactive systems in a declarative manner. In particular, they provide the ability to reason over events, actions and their effects, and allow detecting events and responding to them automatically. Various reaction rule approaches have been developed, which for the most part have been advanced separately, hence led to different views and terminologies. This chapter surveys and classifies the wide variety of rule-based calculi approaches, engines and languages for event, action and state processing, and describes their main features. Founded on the original formalisms, major lines of development are traced to the present and extrapolated to the future.

Plant functional traits are fundamental to the understanding of plant adaptations and distributions. Recently, scientists proposed a trait-based species selection theory to support the selection of suitable plant species to restore the degraded ecosystems, to prevent the invasive exotic species and to manage the sustainable ecosystems. Based on this theory, in a previous study, we developed a species screening model and successfully applied it to a project where plant species were selected for restoring a tropical coral island. However, during this process we learned that a software platform is necessary to automate the selection process because it can flexible to assist users. Here, we developed a generalized software platform called the “Restoration Plant Species Selection (RPSS) Platform.” This flexible software is designed to assist users in selecting plant species for particular purposes (e.g., restore the degraded ecosystems and others). It is written in R language and integrated with external R packages, including the packages that computing similarity indexes, providing graphic outputs, and offering web functions. The software has a web-based graphical user interface that allows users to execute required functions via checkboxes and buttons. The platform has cross-platform functionality, which means that it can run on all common operating systems (e.g., Windows, Linux, macOS, and others). We also illustrate a successful case study in which the software platform was used to select suitable plant species for restoration purpose. The objective of this paper is to introduce the newly developed software platform RPSS and to provide useful guidances on using it for various applications. At this step, we also realized that the software platform should be constantly updated (e.g., add new features) in the future. Based on the existing successful application and the possible updates, we believe that our RPSS software platform will have broader applications in the future.

The language history questionnaire (LHQ) is an important tool for assessing the linguistic background of bilinguals or second language learners and for generating self-reported proficiency in multiple languages. Previously we developed a generic LHQ based on the most commonly asked questions in published studies (Li, Sepanski & Zhao, 2006). Here we report a new web-based interface (LHQ 2.0) that has more flexibility in functionality, more accuracy in data recording, and more privacy for users and data. LHQ 2.0 achieves flexibility, accuracy, and privacy by using dynamic web-design features for enhanced data collection. It allows investigators to dynamically construct individualized LHQs on the fly and allows participants to complete the LHQ online in multiple languages. Investigators can download and delete the LHQ results and update their user and experiment information on the web. Privacy issues are handled through the online assignment of a unique ID number for each study and password-protected access to data.
