Revisionary taxonomy is frequently dismissed as merely descriptive, which belies its strong intellectual content and hypothesis-driven nature. Funding for taxonomy is inadequate and largely diverted to studies of phylogeny that neither improve classifications nor nomenclature. Phylogenetic classifications are optimal for storing and predicting information, but phylogeny divorced from taxonomy i...

Introduction: Resident promotion exams are considered one of the most important summative exams in residency period that allow residents to proceed to a higher grade. Multiple choice questions are the most common and objective test in medical science education. Therefore, finding methods to improve quality of exams, particularly in specialty programs, is important. The aim of this study is to d...

OBJECTIVE To describe the development of the Oxford Food and Activity Behaviors (OxFAB) taxonomy and questionnaire to explore the cognitive and behavioral strategies used by individuals during weight management attempts. METHODS The taxonomy was constructed through a qualitative analysis of existing resources and a review of existing behavior change taxonomies and theories. The taxonomy was t...

Many classifications of attacks have been tendered, often in taxonomic form. A common basis of these taxonomies is that they have been framed from the perspective of an attacker – they organize attacks with respect to the attacker’s goals, such as privilege elevation from user to root (from the well known Lincoln taxonomy). Taxonomies based on attacker goals are attack-centric; those based on d...

The notion of the information technology (IT) artifact has received a great deal of attention, particularly since Benbasat and Zmud’s (2003) call for it to be the core of the information systems discipline. Yet, little work has focused on defining and discussing the IT artifact in a way that can facilitate consistent treatment across studies. In this paper, we develop a taxonomy of the IT artif...

Taxonomy, the science of naming and classifying organisms, is the original bioinformatics and a fundamental basis for all biology. Yet over the past few decades, teaching and funding of taxonomy has declined. Last year, taxonomy suddenly became fashionable again, and revolutionary approaches to taxonomy using DNA and Internet technology are now being contemplated. For examples, see the article ...

The linguistic categorisation of compounds dates back to some of the earliest work in linguistics. The cross-linguistic compound taxonomy of Bisetto and Scalise (2005), later refined in Scalise and Bisetto (2009), is well-known in linguistics for understanding the grammatical relations in compounds. Although this taxonomy has not been used extensively in the field of computational linguistics, ...

The principal aim of this paper is to apply the Taxonomy of Software Evolution, developed by Mens et. al [1], to position various software tools that support the activity of software refactoring as part of the evolutionary process. This taxonomy is based on the mechanisms of change and the factors that impact upon these mechanisms. The goal of this taxonomy is to position concrete tools and tec...

We want to help developers and security practitioners understand common types of coding errors that lead to vulnerabilities. By organizing these errors into a simple taxonomy, we can teach developers to recognize categories of problems that lead to vulnerabilities and identify existing errors as they build software. The information contained in our taxonomy is most effectively enforced via a to...

ویژگیهای دانه گرده 43 گونه متعلق به 32 جنس از تیره گاوزبان با استفاده از میکروسکوپ الکترونی اسکن و بعضی مواقع با میکروسکوپ نوری مورد بررسی قرار گرفته است. نتایج حاصله نشان می دهد که تعداد زیادی از گونه ها با صفات گرده شناسی از یکدیگر تشخیص داده می شوند (eurypalinous). نتایج دیرینه شناسی مشخص می کند که دانه گرده از شکل 3 شیار- روزنی شروع و سایر اشکال از آن مشتق می شوند و در مراحل اولیه به دو گرو...
