The current structure of 583 Magnoliopsida (Dicotyledons) and 584 Liliopsida (Monocotyledons) in the Dewey Decimal Classification (DDC) system reflects changes made when the life sciences were thoroughly revised in 1996. Since that time, considerable progress has been made in the phylogenetic classification of angiosperms (flowering plants). In particular, APG III, the 2009 version of the classification developed by the Angiosperm Phylogeny Group, is finding use as a tool to organize both botanical information and botanical collections. The Dewey Editorial Office has received a request to revise 583–584 in light of this taxonomy ―as appropriate‖; relevant revisions would be likely to include both structural and terminological changes. In deciding how to provide accommodation for APG III, the Dewey editorial team must address many issues: Is APG III now stable enough and accepted broadly enough to be adopted as the basis for a major revision of the DDC? Should revisions in 583–584 be coordinated with parallel revisions in other parts of the life sciences? What revision strategies can be considered in revising 583-584 to accommodate APG III? What are their various strengths and weaknesses? How have other major classification schemes (e.g., the UDC) accommodated APG III? Discussion of these issues is guided by the principles (―editorial rules‖) that govern development of the DDC.

Purpose The study aims to explore the classification of electronic games in Dewey decimal classification (DDC) and The Library of Congress classification (LCC) schemes. Design/methodology/approach The study adopted a comparative analytical method to explore the topic in both the DDC and the LCC schemes by comparing its processing method in both schemes. The study measures the extent to which both schemes succeed in allocating notations covering the topic’s literature. Findings The study reached several results, the most important of which are: the difference between the two main cognitive sections, to which they belong to the topic, namely, arts and recreation (700) in the DDC scheme and the geography section (G) in the LCC scheme, while they were found to share the same sub-section scheme. The two schemes do not allocate notations to address the subject of electronic games as literature and other notations that have not been embodied for electronic games themselves or in the form of a compact disc or other media. Originality/value As far as we know, this is the first paper that compares the treatment of video games in DDC and Library of Congress classification schemes. The study allows for understanding the difference in the treatment of topics in both schemes, which would help in the decision of the adoption of a particular classification scheme.

ABSTRACT OBJECTIVE To review current classification systems for adolescent and adult scoliosis. METHODS The literature was reviewed in reference to scoliosis classification systems for adolescent and adult scoliosis. RESULTS There are multiple classification systems for scoliosis. Classification of scoliosis is dependent on patient age, spinal abnormality, scoliotic curve, and global spinal alignment. To date, classification systems have focused predominantly on adolescent idiopathic scoliosis or adult/degenerative scoliosis; a single classification system evaluating scoliotic deformities of different ages and spinal abnormalities has not been identified. CONCLUSION The importance of scoliosis classification schemes lies in their ability to standardize communication among health care providers. With regard to the classification of adolescent scoliosis, the Lenke system has addressed many of the significant limitations of the King system and is now the standard classification scheme. Classification schemes for adult scoliosis have been reported only recently, and each offers specific advantages (the simple pathogenesis-based system of Aebi, the strong clinical relevance of the Schwab system, and the richly descriptive Scoliosis Research Society system). This article highlights the salient features of currently used scoliosis classification systems.

Semantic Typology

In this article I explore how typological approaches can be used to construct novel classification schemes for Arabic dialects, taking the example of definiteness as a case study. Definiteness in Arabic has traditionally been envisioned as an essentially binary system, wherein definite substantives are marked with a reflex of the article al- and indefinite ones are not. Recent work has complicated this model, framing definiteness instead as a continuum along which speakers can locate referents using a broader range of morphological and syntactic strategies, including not only the article al-, but also reflexes of the demonstrative series and a diverse set of ‘indefinite-specific’ articles found throughout the spoken dialects. I argue that it is possible to describe these strategies with even more precision by modeling them within cross-linguistic frameworks for semantic typology, among them a model known as the ‘Reference Hierarchy,’ which I adopt here. This modeling process allows for classification of dialects not by the presence of shared forms, but rather by parallel typological configurations, even if the forms within them are disparate.

Giant cell tumor of bone is considered by his behavior a benign but aggressive neoplasm. The objective of our study was to determine if there is a correlation between the Campanacci’s radiological classification of giant cell tumors of bone and the expression by immunohistochemistry of Cyclin D1 and proliferation cell nuclear antibody (PCNA). A retrospective and descriptive study was made. In total, there were 27 cases. All cases showed Cyclin D1 and PCNA positivity. Rho Spearman for Campanacci and Cyclin D1 expression was 0.06 and for Campanacci and PCNA was 0.418. We conclude that there is a positive correlation between PCNA expression in giant cell tumors of Bone and the Campanacci’s radiological classification II and III, butCyclin D1 expression was no related with radiologic features.

Objective: Over the past two decades, a number of systems have been developed for the classification of cognitive and behavioural abnormalities in older people, in order that individuals at high risk of developing neurodegenerative disease, particularly Alzheimer's disease, may be identified well before the disease manifests clinically. This article critically examines the inclusion and exclusion criteria of a number of such classification systems, to determine the effect that variations in criterion may have on clinical, behavioural and neuroimaging outcomes reported from older people with mild cognitive impairment. Method: Qualitative review of the literature describing systems of classifying mild cognitive impairment, and outcomes from clinical, behavioural, neuroimaging and genetic studies of older people with mild cognitive impairment. Results: The exclusion and inclusion criteria for these classification systems vary markedly, as do the design of studies upon which the validity of these systems has been assessed. Minor changes to individual exclusion/inclusion criterion may result in substantial changes to estimates of the prevalence and clinical outcome of mild cognitive impairment, while inadequate experimental design may act to confound the interpretation of results. Conclusions: As a result of these factors, accurate and consistent estimates of the outcome of mild cognitive impairments in otherwise healthy older people are yet to be obtained. On the basis of this analysis of the literature, optimal criteria via which accurate classifications of mild cognitive impairment can be made in future are proposed.

A ring R is said to be an AE-ring if every additive endomorphism is a ring endomorphism. In this paper further steps are made toward solving Sullivan's Problem of characterising these rings. The classification of AE-rings with. R3 ≠ 0 is completed. Complete characterisations are given for AE-rings which are either: (i) subdirectly irreducible, (ii) algebras over fields, or (iii) additively indecomposable. Substantial progress is made in classifying AE-rings which are mixed – the last open case – by imposing various finiteness conditions (chain conditions on special ideals, height restricting conditions). Several open questions are posed.

Abstract The writing of this paper aims to (1) find out the classification of Minangkabau traditional musical instruments; (2) knowing the process of classifying Minangkabau traditional musical instruments; (3) knowing the obstacles and efforts to overcome obstacles in the process of classifying Minangkabau traditional musical instruments. Writing this paper using descriptive research methods. Data was collected based on observations and interviews from various sources. Based on the results of the study it can be concluded as follows, first classifying the traditional Minangkabau musical instrument the first step taken is data collection and data compilation. Then classify musical instruments based on the types of musical instruments which are divided into five, namely striking, blowing, striking, picking and pressing musical instruments, but there are only four types of musical instruments in Minangkabau, namely striking, blowing, striking and picking instruments. The types of musical instruments are classified according to the guidelines on DDC (dewey decimal classification). The two processes of classifying traditional musical instruments have several parts, as follows: (1) Dewey's classification; (2) Determine the Main Class; (3) Determine Divisions; (4) Determine the Section. The three obstacles in the process of classifying traditional Minangkabau musical instruments are as follows: (1) lack of information regarding musical instruments in the Minangkabau Region including the area of origin of the musical instruments; (2) the difficulty of grouping musical instruments based on the type of musical instrument, because many names of musical instruments are almost the same. Efforts to overcome obstacles in the process of classifying Minangkabau traditional musical instruments are as follows: (1) conducting the process of collecting all data derived from several literatures and institutions that store traditional Minangkabau musical instruments; (2) pay close attention to musical instruments to be grouped according to the type of music.Keywords: classification; traditional musical instruments; minangkabau
