A special issue (SI) titled “Microbial Diversity in Extreme Environments: Implications for Ecological and Applicative Perspectives” has been launched with the aim of showcasing the diversity and biotechnological potential of extremophilic microorganisms. The issue includes 10 research papers and four reviews that mainly address prokaryotes inhabiting hyperarid, hypercold, hyperalkaline and hypersaline (or polyextreme) environments, spanning from deserts to meromictic and glacier lakes around the globe. Thermophilic prokaryotes from shallow hydrothermal vents and Antarctic geothermal soils are also treated. The ecology and biotechnological perspectives of eukaryotes are discussed in two review papers and one research paper. This special issue serves as a memorial to Dr. Luigi Michaud (1974–2014), who dramatically passed away in Antarctica during underwater sampling activities.

The application of modern advanced techniques in molecular biology is revealing unexpectedly high levels of microbial diversity and complexity. However, the invisible loss of microbial diversity in the environment deriving, for example, from global changes and anthropogenic activities, is not really perceived. In this context, culture collections worldwide have become a valuable resource for the sustainable use of microbial diversity and its conservation. They provide pure cultures and genetic materials that are required for a number of research and teaching purposes, as well as for bioprospecting aims and their subsequent exploitation in biotechnological fields. This Special Issue has been launched with the aim of showcasing the diversity and biotechnological potential of microorganisms (e.g., Bacteria, Archaea, cyanobacteria, microalgae, fungi, yeasts, and protozoa) belonging to culture collections kept worldwide.

Extreme environments are hostile for most organisms, but such habitats represent suitable settings to be inhabited by specialized microorganisms. A marine shallow-water hydrothermal vent field is located offshore in northeast Taiwan, near the shallow shore of the southeast of Kueishantao Island (121°55′ E, 24°50′ N). Research on extremophilic microorganisms makes use of the biotechnological potential associated with such microorganisms and their cellular products. With the notion that extremophiles are capable of surviving in extreme environments, it is assumed that their metabolites are adapted to function optimally under such conditions. As extremophiles, they need specific culture conditions, and only a fraction of species from the original samples are recovered in culture. We used different non-selective and selective media to isolate bacterial species associated with the hydrothermal vent crab Xenograpsus testudinatus and the sediments of its habitat. The highest number of colonies was obtained from Zobell marine agar plates with an overall number of 29 genetically distinct isolates. 16sRNA gene sequencing using the Sanger sequencing method revealed that most of the bacterial species belonged to the phylum Firmicutes and the class Bacilli. The present study indicates that hydrothermal vent bacteria and their secondary metabolites may play an important role for the reconstruction of the evolutionary history of the phylum Procaryota.

For years, achievements and discoveries made by researcher are made aware through research papers published in appropriate journals or conferences. Many a time, established s researcher and mainly new user are caught up in the predicament of choosing an appropriate conference to get their work all the time. Every scienti?c conference and journal is inclined towards a particular ?eld of research and there is a extensive group of them for any particular ?eld. Choosing an appropriate venue is needed as it helps in reaching out to the right listener and also to further one’s chance of getting their paper published. In this work, we address the problem of recommending appropriate conferences to the authors to increase their chances of receipt. We present three di?erent approaches for the same involving the use of social network of the authors and the content of the paper in the settings of dimensionality reduction and topic modelling. In all these approaches, we apply Correspondence Analysis (CA) to obtain appropriate relationships between the entities in question, such as conferences and papers. Our models show hopeful results when compared with existing methods such as content-based ?ltering, collaborative ?ltering and hybrid ?ltering.

In recent years I've supervised countless undergraduate research papers and numerous senior theses. Not surprisingly, I repeat myself about basic research and writing hints, suggestions, and outright warnings. This handout, “Write Tigers Write!” prepared for the “tigers” at Princeton and The Colorado College (the mascot is the same), attempts to help the novice researcher and is, as well, an act of self-protection.What follows are suggestions and cautions for students writing a research paper. My suggestions are merely that. They are personal, general and speak more about writing than about research.Make no mistake about it. Research and writing are demanding work even for the professional. You won't hear professional scholars or writers boast about the easiness of their craft. No matter how much they love it, and they often love it more than anything else, they find it demanding, exacting, lonely and often painful—if they really work at it.

A Review of: Schwegler, R. A., and Shamoon, L. K. (1982). The aims and process of the research paper. College English, 44(8), 817-824. Objectives – This classic article discusses research-based writing assignments. Schwegler and Shamoon sought to identify differences between college students’ and college instructors’ conceptions of research and research paper assignments, particularly in terms of their purpose and process. The authors also sought to identify common features of academic research writing that could inform writing instruction about research writing. Design – Qualitative interviews with college instructors and students about their views of the research process and about forms of research writing. Instructors were also interviewed about evaluation standards for academic research papers. Setting – Unspecified, though the description suggests a college or university in the United States. Subjects – College instructors and college students. (Number of subjects unspecified.) Methods – The authors, a university writing program director and a writing program instructor, conducted one-on-one interviews with college instructors and students about their views of research and the research paper. Questions focused on conceptions of the research process, the purposes of research, and the forms that research writing takes. Instructors were also asked about standards for effective evaluation of research papers. The limited description of the research methods and interview questions employed in this study hinder the ability to critically assess its validity and reliability. Potential limitations of the study, such as selection bias or unclear wording of interview questions, cannot be adequately assessed based on the provided information. The authors also do not identify limitations of their study. As is discussed in more detail in this review’s commentary, the study does not conform to the conventions of most research studies from the behavioral, health, physical, and social sciences. The authors’ methods, however, may be better understood in light of particular disciplinary approaches and debates in Composition Studies. Main Results – Interviewees’ responses illustrated notable differences between college instructors’ and college students’ conceptions of the process, purpose, forms, and audiences of research paper assignments. While instructors understood the research paper to be argumentative, analytical, and interpretive, students generally described it as informative and factual. Students, when asked why research papers are assigned, identified purposes such as learning more about a topic, demonstrating one’s knowledge, or learning to use the library. Instructors indicated that the purpose of the research paper includes testing a theory, building on previous research, and exploring a problem that has been presented by other research or events (p. 819). At the same time, most instructors described research as an ongoing pursuit of “an elusive truth” (p. 819), rather than as primarily factual in nature. According to Schwegler and Shamoon, instructors also indicated during interviews that research and writing involve a clear though complex pattern that is evident in the structure and conventions of research papers. For example, the research process usually begins with activities like reading, note-taking, identifying problems with and gaps in current research, and conversing with colleagues. These instructors also reported that writing conventions which are implicitly understood in their fields are used by other scholars to evaluate their peers’ work. Reflecting on these interview responses, Schwegler and Shamoon suggest that pedagogical approaches to writing instruction can be informed both by acknowledging disparities in students’ and instructors’ conceptions of research and by identifying shared characteristics of academic writing. The authors therefore make several general observations about the nature of professional research papers and describe the structure and conventions of academic research papers. They conclude that the structure of scholarly research papers across the disciplines reflects the research process. Such a paper opens with identification of a research problem and a review of current knowledge and is followed by a variation of four possible patterns: 1) Review of research, 2) Application or implementation of a theory, 3) Refute, refine, or replicate prior research, and 4) Testing a hypothesis ( pp. 822-823). Schwegler and Shamoon indicate that the key features of scholars’ writings are also apparent in student research papers which instructors evaluate as highly-ranked and absent in lower-ranked papers. Furthermore, they provide an appendix that outlines the essential textual features of a research paper (Appendix A) (p. 822). It is unclear, however, if these descriptions of scholarly research writing are based on the instructor interviews or on other sources, such as previous analytical studies or an analysis of academic research papers from various disciplines. The researchers do not articulate the specific methods used to arrive at their generalizations. Conclusion – The authors conclude that students’ and instructors’ differing conceptions of the research process and the research paper have important implications for writing instruction. Many of the interviewed instructors described research as involving methods that are quite different from those needed for most research paper assignments. The discrepancies between class assignments and academics’ approaches to research suggests that differences in instructors’ and students’ views of research often are not addressed in the design of research paper assignments. Instructors who teach the research paper should ensure that the purpose, structure, and style of assignments reflect what content-area instructors will expect from students. Schwegler and Shamoon argue that because the basic conventions of the research paper generally apply across disciplines, instruction about those conventions can be integrated into composition courses and lower-level undergraduate courses. Such an approach can assist students in better understanding and approaching research writing as would a scholar in the given discipline.
