This bioacoustics activity combines concepts in invertebrate taxonomy, animal communication, and acoustical physics while providing a unique opportunity for physics and biology teachers to collaborate and introduce their students to an exciting, interdisciplinary research field. Here, we propose a lab- and field-based activity that uses hydrophones to explore how shrimp snapping behavior changes in response to different stimuli and introduces students to the process of scientific inquiry. Using free software, students use spectrograms to visualize and analyze their experimental data. Furthermore, we propose potential modifications to the lab for classrooms without easy access to marine environments or snapping shrimp.

A micropipette aspiration technique was adopted to investigate the viscoelastic properties of phagocytes of arteriosclerotic origin. A standard linear solid model was employed to fit the experimental data and three viscoelastic coefficients were used to compare the mechanical properties of the phagocytes in different phases during arteriosclerostic development. The experimental results indicated that prior to the formation of arteriosclerosis, the mobility and deformability of the marcopahges matured from monocytes decreased, and their rigidity increased. At the initial stage of arteriosclerosis formation, the mobility and deformability of the foam-cells further decreased. This finding may have important implication in the research field of arteriosclerosis.

Decision under uncertainty is an active interdisciplinary research field. A decision process is generally identified as the action of choosing an alternative that best suites our needs. This process generally includes several areas of research including but not limited to Economics, Psychology, Philosophy, Mathematics, Statistics, etc. In this chapter the authors attempt to create a framework for uncertainties which surrounds the environment where human decision making takes place. For this purpose, the authors discuss how one ought to handle uncertainties within Fuzzy Logic. Furthermore, they present recent advances in Type 2 fuzzy system studies.

Abstract The Forester's Yield Curve Designer(FYCD) software is aimed at helping forest management planners and field foresters in the development and validation of timber volume yield curves. It uses a mouse-driven graphical user interface that facilitates the import and display of results from stand growth models, the comparison of potential curves with permanent sample plot data, and the creation of new curves by drawing, adjusting, and combining curves. FYCD addresses the problem of getting management plan volume yield curve information out to field foresters for validation against available data and experience, and facilitating feedback from the forester to the planner. FYCD also increases the usability of valuable data from permanent and temporary sample plots by allowing easy access and display. This paper describes the primary functionality of FYCD, the data formats used, and how to obtain this free software from the Canadian Forest Service. North. J. Appl. For. 15(1):23-27.

Purpose This paper aims to the identification of journal articles that probably report on interdisciplinary research at Wageningen University & Research (WUR). Design/methodology/approach For identification of interdisciplinary research, an analysis is performed on journals from which articles have been cited in articles (co-)authored by WUR staff. The journals with cited articles are inventoried from the reference lists of the WUR articles. For each WUR article, a mean dissimilarity is calculated between the journal in which it has been published and the journals inventoried from the reference lists. Dissimilarities are derived from a large matrix with similarity values between journals, calculated from co-occurrence of these journals in the WUR articles’ reference lists. Findings For 21,191 WUR articles published between 2006 and 2015 in 2,535 journals mean dissimilarities have been calculated. The analysis shows that WUR articles with high mean dissimilarities often are published in multidisciplinary journals. Also, WUR articles with high mean dissimilarities are found in non-multidisciplinary (research field-specific) journals. For these articles (with high mean dissimilarities), this paper shows that citations are often made to more various research fields than for articles with lower mean dissimilarities. Originality/value Identification of articles reporting on interdisciplinary research may be important to WUR policy for strategic purposes or for the evaluation of researchers or groups. Also, this analysis enables to identify journals with high mean dissimilarities (due to WUR articles citing more various research fields). Identification of these journals with a more interdisciplinary scope can be important for collection management by the library.

This article suggests a cohesive articulation of the shared basis upon which the interdisciplinary research field of law and linguistics is developing, organising the research around the familiar three branches of the state: legislature, executive and judiciary, thus providing a map oriented towards non-linguists and legal practitioners. It also invites interdisciplinary scholars to critically reflect on future directions for this research area. This effort to redress the lack of recognition within the law of relevant linguistic research is part of our pursuit of an alternative and more collaborative approach to legal scholarship and law reform addressing issues of communicative barriers and linguistic injustice.

Confidence regression is a significant research field of confidence machine learning. This paper adopts KNN algorithm as a tool, and performs error evaluation on results of regressive learning to classify the accept field and the refuse field so as to achieve the confidence regression. By setting specific error value, this approach achieves controllable confidence regression, which has been tested on experimental data of bodyfat and other data sets. The experimental results presented show the feasibility of our approach.

Purpose: The present study was aimed at investigating the characteristics of tourist media content in cyberspace. The characteristics regarding the reflection and survey of tourist attractions in the Russian regions were also analyzed. Methodology: Data on the empirical research field was collected through tourist feedback on the Internet, as well as other social studies studied the wide-ranging relationship of users with media space. Visual media and contemporary time were identified among the most well-known sources of information about services and tourist facilities. Available sentiments with a variety of information available in cyberspace included: inclusive communication, comprehensiveness, pragmatism and using literal communication and providing easy access. In this paper, the outcomes of the outlook for tourism advancement by the help of the media were also discussed. Result: Tourism media, as well as the expansion flow and evolution regarding receiving and construction and increasing the information to respond to the key questions of the development of the tourism industry, were studied such as infrastructure equipment and services and the potential of the tourist industry. The content of cyber media was found to be helpful in consolidating the issues and modes and practical cases of various tourist groups, as well as representing the expectations and interests of tourism industry consumers. The popularity of media content has created vast opportunities for creators and users of information including personalization of demands, flexible communication, and the feasibility of introducing characters by presenting in virtual online space about the time spent on holidays. Applications: This research can be used for the universities, teachers and education students. Novelty/Originality: In this research, the model of the tourist attraction in Russian regions in cyberspace: new tendencies of tourism media marketing is presented in a comprehensive and complete manner.

Purpose – The study aims to explore the interaction between the students, the material objects surrounding them, and their social site. The purpose of this paper is to identify and elucidate information literacy as it is being enacted within a complex and heterogeneous community of PhD students. Design/methodology/approach – The study is conducted from a practice-based perspective, according to which information literacy is conceived as learnt through interaction within the socio-material practice where the learner is active. In order to produce empirical material, semi-structured interviews were conducted with ten doctoral students in an interdisciplinary research network, and their workplaces were visited. Findings – The PhD students in this interdisciplinary network are more or less constantly engaged in the enactment of information literacy. It takes place in dialogue with others who can be both co-located and distantly located, and occurs through discussions about work in progress, through processes of evaluation and assessment of texts and authors, and through mundane everyday activities such as participating in meetings, which offer insights into how to navigate, in the broadest sense, the world of academia. A crucial part of the enactment of information literacy, which in practice is inseparable from interaction with others, is to pay attention to physical surroundings and material objects. Practical implications – The findings have implications for prospective PhD students in interdisciplinary fields, for their supervisors, and potentially also for librarians who are supposed to serve these groups. Originality/value – Research on the information literacies of PhD students in interdisciplinary fields is scarce. The practice-based approach applied in this study offers an extended and deepened understanding of the enactment of information literacy among PhD students in one interdisciplinary research practice.
