    Citizen science for observing and understanding the Earth

    Citizen Science, or the participation of non-professional scientists in a scientific project, has a long history—in many ways, the modern scientific revolution is thanks to the effort of citizen scientists. Like science itself, citizen science is influenced by technological and societal advances, such as the rapid increase in levels of education during the latter part of the twentieth century, or the very recent growth of the bidirectional social web (Web 2.0), cloud services and smartphones. These transitions have ushered in, over the past decade, a rapid growth in the involvement of many millions of people in data collection and analysis of information as part of scientific projects. This chapter provides an overview of the field of citizen science and its contribution to the observation of the Earth, often not through remote sensing but a much closer relationship with the local environment. The chapter suggests that, together with remote Earth Observations, citizen science can play a critical role in understanding and addressing local and global challenges

    Realising the full potential of citizen science monitoring programs

    Citizen science is on the rise. Aided by the internet, the popularity and scope of citizen science appears almost limitless. For citizens the motivation is to contribute to "real" science, public information and conservation. For scientists, citizen science offers a way to collect information that would otherwise not be affordable. The longest running and largest of these citizen science programs are broad-scale bird monitoring projects. There are two basic types of protocols possible: (a) cross-sectional schemes such as Atlases - collections of surveys of many species contributed by volunteers over a set period of time, and (b) longitudinal schemes such as Breeding Bird Surveys (BBS) - on-going stratified monitoring of sites that require more coordination. We review recent applications of these citizen science programs to determine their influence in the scientific literature. We use return-on-investment thinking to identify the minimum investment needed for different citizen science programs, and the point at which investing more in citizen science programs has diminishing benefits. Atlas and BBS datasets are used to achieve different objectives, with more knowledge-focused applications for Atlases compared with more management applications for BBS. Estimates of volunteer investment in these datasets show that compared to cross-sectional schemes, longitudinal schemes are more cost-effective, with increased BBS investment correlated with more applications, which have higher impact in the scientific literature, as measured by citation rates. This is most likely because BBS focus on measuring change, allowing the impact of management and policy to be quantified. To ensure both types of data are used to their full potential we recommend the following: elements of BBS protocols (fixed sites, long-term monitoring) are incorporated into Atlases; regional coordinators are in place to maintain data quality; communication between researchers and the organisations coordinating volunteer monitoring is enhanced, with monitoring targeted to meet specific needs and objectives; application of data to under-explored objectives is encouraged, and data are made freely and easily accessible.

    Object-Oriented Database Technology Applied to Distributed Simulation

    No full text
    There are several ways in which object-oriented database technology can be harnessed to assist in the implementation of simulation packages. We have already integrated our own simulation environment, HASE, with a commercially-available object-oriented database management system. In particular, we use the database system's transaction processing and object persistence facilities. We are currently extending the HASE simulation environment so that it can exploit distributed computing facilities by using the distributed client /server architecture of the object-oriented database system. We are taking this approach in order to parallelize an experiment rather than an individual simulation run. 1 Introduction For some time now, the developers of process-based, discrete-event simulation packages have been aware that there may be advantages to be obtained by using database technology in their products. As simulation experimenters become increasingly ambitious in what they attempt to simulate,..

    Leadership development for orthopaedic trauma surgeons in Latin America: opportunities for and barriers to skill acquisition.

    IntroductionThere is growing interest in leadership courses for physicians. Few opportunities are available in global regions with limited resources. This study describes orthopaedic trauma surgeons' desired leadership skill acquisition, opportunities, and barriers to course participation in Latin America.MethodsLatin American orthopaedic trauma surgeons from the Asociación de Cirujanos Traumatólogos de las Americas (ACTUAR) network were surveyed. This survey solicited and gauged the surgeons' level of interest in leadership topics and their relative importance utilizing a 5-point Likert-scale. Additionally, comparisons were calculated between middle-income countries (MICs) and high-income countries (HICs) to ascertain if needs were different between groups. The survey included demographic information, nationality, level of training, years in practice, leadership position, needs assessment, and perceived barriers for leadership educational opportunities.ResultsOne hundred forty-four orthopaedic surgeons completed the survey, representing 18 countries across Latin America; 15 MICs and 3 HICs. Participants had more than 20 years in practice (49%) and held leadership positions (81%) in hospital settings (62%), national orthopaedic societies (45%), and/or clinical settings (40%). Sixty-three percent had never attended a leadership course due to lack of opportunities/invitations (69%), difficulty missing work (24%), and costs (21%). Ninety-seven percent expressed interest in attending a leadership course. No difference in needs was determined between respondents from MICs and HICs. Professional Ethics, Crisis Management/Organizational Change Management, and High Performing Team-Building were identified as the most important leadership topics.ConclusionOrthopaedic surgeons in Latin America demonstrate an interest in acquiring additional leadership skills but have few opportunities. Identifying interests, knowledge gaps, and core competencies can guide the development of such opportunities
