Limitations Of Classification Systems Research Articles

Fractures in the framework: limitations of classification systems in psychiatry .

This article examines the limitations of existing classification systems from the historical, cultural, political, and legal perspectives. It covers the evolution of classification systems with particular emphasis on the DSM and ICD systems. While pointing out the inherent Western bias in these systems, it highlights the potential of misuse of these systems to subserve other agendas. It raises concerns about the reliability, validity, comorbidity, and heterogeneity within diagnostic categories of contemporary classification systems. Finally, it postulates future directions in alternative methods of diagnosis and classification factoring in advances in artificial intelligence, machine learning, genetic testing, and brain imaging. In conclusion, it emphasizes the need to go beyond the limitations inherent in classifications systems to provide more relevant diagnoses and effective treatments.

Uma abordagem metodológica sobre as possibilidades e limites da comunicação em multiescrita

Este artigo aborda questões que giram em torno da estrutura teórica e metodológica necessária ao suporte de profissionais de comunicação, no âmbito da tipografia digital. O trabalho apoia-se em três temas interligados: as limitações dos sistemas de classificação de faces de tipo quanto ao suporte que oferecem à compreensão dos seus estilos, os critérios adotados por designers e empresas produtoras na escolha das escritas que compõem novas fontes tipográficas e os métodos adequados para o design tipográfico em mais de uma escrita. O propósito e a contribuição específica do artigo são, a partir da reunião e análise crítica de ideias de especialistas como, Charles Bigelow, Cris Holmes, Maxim Zhukov e Robert Bringhurst,sistematizar e estabelecer critérios que subsidiem o trabalho de designers tipográficos e demais profissionais da comunicação escrita como editores, tipógrafos, designers gráficos e de livros.

World Health Organization and International Prognostic Scoring System: The Limitations of Current Classification Systems in Assessing Prognosis and Determining Appropriate Therapy in Myelodysplastic Syndromes

The myelodysplastic syndromes (MDS) are a heterogeneous group of disorders with a wide range of clinical and pathologic manifestations. A number of prognostic and morphologic classifications have been developed that can be helpful in terms of defining the characteristics of populations of patients in clinical trials and longitudinal observational studies, and sometimes in allowing comparisons of the outcomes of different treatment approaches. They are less helpful in guiding treatment decisions in individual patients and, unfortunately, provide little insight into the poorly understood biology of MDS. The merits and limitations of these classification systems are discussed.

Classification of pressure sores: 1.

It is anticipated that the forthcoming national clinical guidelines for the prevention and management of pressure sores will attempt to clarify pressure sore classification. There are many classification systems available, but to date not one has emerged as all-encompassing. A classification system has to be sufficiently detailed to allow accurate assessment of pressure sores. So far this has been difficult to achieve, particularly for pressure sores that do not involve a break in the skin. The assessment forms the basis upon which the patient's care will be planned. There are ethical, legal and financial implications if the assessment is unable to reflect accurately the true nature of the patient's pressure sore. Nurses have attempted to integrate pressure sore classification into the holistic patient assessment process. Their attempts are often thwarted by the limitations of the classification systems currently available. As a result a patient's pressure sore is allocated a classification in which the criteria chosen are nearest to the visual description of the sore, but do not accurately represent the true extent of tissue damage. This article, the first of two parts, highlights the problems of patient assessment and the limitations of current classification systems.
