Social media data for conservation science : A methodological overview
Improved understanding of human-nature interactions is crucial to conservation science and practice, but collecting relevant data remains challenging. Recently, social media have become an increasingly important source of information on human-nature interactions. However, the use of advanced methods for analysing social media is still limited, and social media data are not used to their full potential. In this article, we present available sources of social media data and approaches to mining and analysing these data for conservation science. Specifically, we (i) describe what kind of relevant information can be retrieved from social media platforms, (ii) provide a detailed overview of advanced methods for spatio-temporal, content and network analyses, (iii) exemplify the potential of these approaches for real-world conservation challenges, and (iv) discuss the limitations of social media data analysis in conservation science. Combined with other data sources and carefully considering the biases and ethical issues, social media data can provide a complementary and cost-efficient information source for addressing the grand challenges of biodiversity conservation in the Anthropocene epoch.Peer reviewe
Public engagement of scientists (Science Communication)
Public engagement of scientists is defined as âall kinds of publicly accessible communication carried out by people presenting themselves as scientists. This includes scholarly communication directed at peers as well as science communication directed at lay publicsâ (JĂŒnger & FĂ€hnrich, 2019, p. 7).
Field of application/theoretical foundation:
The variable âpublic engagement of scientistsâ can be differentiated according to the following three main dimensions (JĂŒnger & FĂ€hnrich, 2019):
Directions of engagement: Describes the extent to which communication scientists on Twitter connect with people from different sectors of society (e.g. science, politics, media, economy). This allows conclusions to the potential influence of scientists reaching specific audiences beyond the scientific community (JĂŒnger & FĂ€hnrich, 2019).
Topics of engagement: Previous research reveals that social scientists not only act as experts in their research field, but often present themselves as public intellectuals by also referring to political and social issues (AlbĂŠk, Christiansen, & Togeby, 2003; FĂ€hnrich & LĂŒthje, 2017). For this reason, communication scientists are expected to communicate not only on scientific but also on political or economic issues.
Modes of engagement: In addition to disseminating information, social networking sites also allow for more interactive ways of maintaining relationships. Thus, following Ellison and Boyd (2013), it can be assumed that communication on social networking sites can be both content-centered and user-centered. This dimension can be linked to the speech act theory (Klemm, 2000; Searle, 1990), according to which every use of language has a performative function.
References/combination with other methods of data collection:
In some cases, a mixed method approach, employing two data collection methods, is applied: a content analysis is complemented by a survey to gain information about the science communicators such as demographic information (Hara, Abbazio, & Perkins, 2019). Furthermore, their social networks are investigated by means of network analysis (Walter, Lörcher, & BrĂŒggemann, 2019).

An evaluative baseline for geo-semantic relatedness and similarity
In geographic information science and semantics, the computation of semantic similarity is widely recognised as key to supporting a vast number of tasks in information integration and retrieval. By contrast, the role of geo-semantic relatedness has been largely ignored. In natural language processing, semantic relatedness is often confused with the more specific semantic similarity. In this article, we discuss a notion of geo-semantic relatedness based on Lehrerâs semantic fields, and we compare it with geo-semantic similarity. We then describe and validate the Geo Relatedness and Similarity Dataset (GeReSiD), a new open dataset designed to evaluate computational measures of geo-semantic relatedness and similarity. This dataset is larger than existing datasets of this kind, and includes 97 geographic terms combined into 50 term pairs rated by 203 human subjects. GeReSiD is available online and can be used as an evaluation baseline to determine empirically to what degree a given computational model approximates geo-semantic relatedness and similarity
CiĂȘncia da Informação: ciĂȘncia da forma

Information science: form science
Abstract
What is the scientific field of information science? In this paper is developed the idea that information science is concerned by adaptation of the form of the message to a given channel and a fixed goal of communication. Such an aspect, which seems very technical, actually concerns fundamental research. For instance, in the field of written documents, it refers to the problem of reference function to the extra-linguistic reality. Consideration of the same kind can be made about other type of message (fixed image, moving image, radio production, etc.) Conseguently, information science appears as a very vast and partly inexplored scientific field
The Broader Impact of Student-Scientist Partnership: Scientistsâ Contribution to Studentsâ Understanding and Proficiencies of Science
This study aims to investigate the broader impacts of student-scientist partnership with an emphasis on scientistsâ possible contributions to studentsâ understanding and proficiencies of science. Appeals from the National Science Foundation have specifically called for broader participation and direct involvement in science and the enhancement of research and education through the linking of scientists with other programs. The Botanical Society of America's PlantingScience project is a partnership of students, science teachers, and scientist-mentors working together in authentic science learning. This dissertation includes three papers. The first paper is an extensive literature review focusing on how scientists can contribute to studentsâ science learning via online mentoring. The second paper applies a grounded theory approach to build a theory that explains how scientists talk about science when they engage in inquiry activities with students and how this interaction occurs. The third study, which is a mixed methods study, investigates how scientists contribute to studentsâ science proficiencies and what kind of patterns exist between scientist-mentors and student-teams during inquiry engagement.
The literature review reveals an information gap exploring how scientists reflect their understanding of science to K-12 students when they work together in a partnership model. This review pointed out three main questions regarding student-scientist partnerships via online mentoring: (1) What do scientists say about science when they engage in online dialogue about studentsâ inquiry projects? (2) What are the connections between scientistsâ demographics, the subject of the inquiry, and the way they explain the nature of science? and (3) What is the relationship between the quality of studentsâ inquiries and what their mentors reveal about the nature of science in their dialogues? The results of the grounded theory study revealed the educational, social, and cultural means of the interaction between two parties-- students and scientists. Also, investigation of various cases allowed a better understanding of the essence of nature and culture of science from practitionersâ perspectives. Finally, the mixed methods study revealed that scientists contributed to the authenticity of studentsâ inquiry experiences by encouraging them to understand scientific explanations, generate scientific evidence with them, reflect on scientific knowledge, and participate productively in scientific discussions
Meeting user needs for sea level rise information: a decision analysis perspective
Despite widespread efforts to implement climate services, there is almost no literature that systematically analyses users' needs. This paper addresses this gap by applying a decision analysis perspective to identify what kind of mean seaâlevel rise (SLR) information is needed for local coastal adaptation decisions. We first characterize these decisions, then identify suitable decision analysis approaches and the seaâlevel information required, and finally discuss if and how these information needs can be met given the stateâofâtheâart of seaâlevel science. We find that four types of information are needed: i) probabilistic predictions for short term decisions when users are uncertainty tolerant; ii) highâend and lowâend SLR scenarios chosen for different levels of uncertainty tolerance; iii) upper bounds of SLR for users with a low uncertainty tolerance; and iv) learning scenarios derived from estimating what knowledge will plausibly emerge about SLR over time. Probabilistic predictions can only be attained for the near term (i.e., 2030â2050) before SLR significantly diverges between low and high emission scenarios, for locations for which modes of climate variability are well understood and the vertical land movement contribution to local seaâlevels is small. Meaningful SLR upper bounds cannot be defined unambiguously from a physical perspective. Low to highâend scenarios for different levels of uncertainty tolerance, and learning scenarios can be produced, but this involves both expert and user judgments. The decision analysis procedure elaborated here can be applied to other types of climate information that are required for mitigation and adaptation purposes
Official statistics 4.0 - Facts for people in the 21. century
The term âstatisticsâ is used differently; it can refer to a science, a certain kind of information or institutions. Essentially, statistics is the science of learning from data. Certainly, it is a modern technology that is part of the standards of todayâs information age and society and is used in a wide array of fields. The history of statistics goes back a long way, accompanying historical eras, technical developments and political turning points just as the census in year zero. Statistics is a method that can reduce complexity, separate signals from noise and distinguish significant from random. The statistical results of this method are used for all conceivable information and decision-making processes. Whether statistics help us better understand the world around us and whether they actually improve decisions (and therefore our lives) is not only a question of scientific methodology. The decisive factor here is whether statistics, like a language, are understood by those for whom the information is relevant. Statistical institutions are the producers of statistics. Using scientific statistical methods, data is collected and existing data is processed in order to calculate condensed information, which is made available to the general public in different forms, such as statistical aggregates, graphics, maps, accounts or indicators. Statistical offices usually belong to the public administration, at state, international, regional or local level.
This work is concerned neither with statistics in general nor with the history of theoretical statistics. Rather, the goal is to describe the status quo for a particular area of application, namely âofficial statisticsâ, based on an analysis of its historical genesis in order then to deploy strategic lines of development for the near future of this particular domain. Central to this work is the quality of statistical information. Statistics can only develop a positive enlightenment effect on the condition that their quality is trusted. To ensure long-term trust in statistics, it is necessary to deal with questions of knowledge, quantification and the function of facts in the social debate. How can we know that we know what we know (or do not know)? The more concrete an answer that can be given to such questions, the more possible it will be to protect statistics against inappropriate expectations and to address false criticism
Examining the use of drama to develop epistemological understanding about the nature of science: A collective case from experience in New Zealand and England, UK
Understanding the nature of science (NoS) is perplexing for young children because it is concerned with not only understanding how evidence is generated but also what kind of meanings can be made from information collected. However, acting as a scientist-in-role, making independent decisions about what information to collect and deciding how to go about it, can enable students to experience scientific practices that empower them to better appreciate and understand the NOS. This paper illustrates how drama processes, in two international settings in Wellington, New Zealand and Oxford, United Kingdom encouraged nine to ten year old children to engage in the scientific âas-ifâ world. The data collected from these two locations was analysed deductively to illustrate how working-in-role can influence the nature of learning and shape the scientific practices experienced that consequently inform how the NoS is understood. The children in Wellington (New Zealand) worked in-role as atmospheric scientists to design a reduced-emissions race track. The class in Oxford (UK) adopted the role of technological scientists theorising about properties of materials to create and test original carriers designed to transport a range of everyday objects. How drama promoted working-in-role to experience scientific practices supporting the understanding of the NoS, are discussed. The findings suggest that being in-role as a scientist offered learners various opportunities to be agentive, to think and act scientifically, better appreciate the nature of work that scientists do and consequently appreciate the NoS
Educative curricula and improving the science PCK of teachers in middle school settings in rural and remote Australia
Science is one of seven-mandated Key Learning Areas (KLAs) Foundation to Year 10 of the new Australian National Curriculum (ACARA, 2012). Not only, therefore, is science to be offered in every school as part of the curriculum, there is also the expectation that science is to be taught well to all students regardless of location, gender, cultural background or socio-economic status (ACARA, 2012). Studying science provides benefits to individuals by developing their scientific literacy skills (Goodrum, Hackling & Rennie, 2001; Hackling & Prain, 2008). Its study also benefits the national economy by equipping students with the innovative, inventive, and creative skills to generate and apply new ideas as knowledge workers in an interconnected and interdependent global economy (Marginson, Tytler, Freeman & Roberts, 2013; Productivity Commission, 2007).
A study of recent literature, including the national and international data on the middle years of school (ACARA, 2012; ACER, 2011, 2013; Goodrum et al., 2001; Goodrum, Druhan, & Abbs, 2012; Hackling & Prain, 2007; Marginson et al., 2013; Office of the Chief Scientist, 2012; Productivity Commission, 2007), could reasonably be expected to show rural and remote students doing well in science if not at least as well as their metropolitan counterparts. Sadly, this is not the case. Science performance in national and international assessments overall is flat-lining (ACARA, 2011; ACER, 2011, 2013) and the gap between metropolitan, rural and remote students in some assessment data indicates as much as 18 months of difference in schooling in favour of metropolitan students and with the gap increasing with increasing remoteness.
What are the causes of this inequity and how can it be addressed? Science teachers hold the key (Australian Council of Deans of Science, 2005; Dow, 2003a; Goodrum et al., 2001). Improving the effectiveness of science teachers helps improve science learning outcomes for students. One way to improve the effectiveness of science teachers is to improve their Pedagogical Content Knowledge (Kind, 2009b; Magnusson, Krajcik & Borko, 1999; Loughran, 2010; Loughran, Berry & Mulhall, 2006; Shulman, 1986) through professional learning experiences. However, improving teachersâ science PCK in the middle-school years in rural and remote settings through traditional face-to-face professional learning activities poses a number of challenges. These include lack of casual relief teachers, difficulties in attracting and retaining science teachers, the provision of experienced mentors and coaches and, the provision of fewer professional learning opportunities compared with metropolitan areas (Australian Council of Deans of Science, 2005; Australian Secondary Principalâs Association, 2006; National Centre of Science, Information and Communication Technology, and Mathematics Education for Rural and Regional Australia, 2006). Educative curricula designed to improve teachersâ science PCK as well as learning outcomes for students provide an alternative to traditional face-to-face professional learning for teachers in rural and remote locations (Davis & Krajcik, 2005). Can educative curricula help address the inequity in student science outcomes in rural and remote areas?
The Middle Years Astronomy Project (the Project) is an example of one educative curriculum currently in use in the middle years of some rural and remote schools (McKinnon, 2005). This educative curriculum is aligned with the Australian Science Curriculum. It comprises access to telescopes and digital cameras located in NSW (Australia) and Wyoming (USA) that students can control remotely to take photographs of many astronomical phenomena, which can form the basis of further investigations. It also comprises a teachersâ guide designed to improve teachersâ science PCK by providing guidance on designing instructional strategies for science projects with knowledge of five factors in mind. These factors are knowledge of the science content, knowledge of studentsâ alternative conceptions, knowledge of instructional strategies and the most appropriate assessment strategies to employ, knowledge of the science curriculum, and knowledge of personal beliefs and orientations toward science teaching and learning.
This thesis explores the potential for this educative curriculum to improve the PCK of teachers of science in the middle school years in rural and remote settings. It does this by employing a Type IV multiple-case, embedded mixed-methods design (Yin, 2014) over two phases in two states of Australia collecting a range of data from four remote sites in Western Australia and four rural sites in Victoria. Participants comprised 12 teachers, four principals, four teaching principals, one Science KLA Consultant, one Cluster Coordinator and over 200 students. Data were gathered from interviews; archival records; researcher direct observations; an astronomy diagnostic test; student artifacts; and school based documents. A framework, developed from the works of Davis & Krajcik (2005), Kind (2009b) and Magnusson et al. (1999), is used to analyse the data for evidence of changes in teachersâ science PCK.
The results of this research indicate that the Project improved teachersâ science PCK for most teachers. Reasons for this are presented. An emerging phenomenon from the research was the ability of experienced science teachers to move holistically and fluidly between components of PCK to make in the moment pedagogical decisions to improve student learning. This has been referred to as âpinball pedagogical reasoningâ (Mitchell, Pannizon, Keast & Loughran, 2015). The findings of this research have implications for both current practice and future research, providing guidance to teachers and designers of professional learning experiences, including educative curriculum designers, on the areas to target when seeking to develop components of PCK for experienced teachers and on assisting less experienced teachers to acquire the âpinball pedagogical reasoningâ skills of experienced teachers. The findings also suggest that PCK development takes time and requires a planned and systematic approach to teacher career development with support from the employer.
This thesis suggests further areas for research and concludes by arguing that a poor science education, which results in poorer scientific literacy skills and a reduced ability to contribute to, and thrive in, the national and international knowledge economies, adds to the education disadvantage students in rural and remote locations experience relative to their metropolitan peers. It advocates a moral imperative to ensure this does not happen. It also suggests that using educative curricula to improve the PCK of rural and remote science teacher, as well as science student learning outcomes, is a strategy worthy of pursuit
