Why are There so Few Female Computer Scientists?

This report examines why women pursue careers in computer science and related fields far less frequently than men do. In 1990, only 13% of PhDs in computer science went to women, and only 7.8% of computer science professors were female. Causes include the different ways in which boys and girls are raised, the stereotypes of female engineers, subtle biases that females face, problems resulting from working in predominantly male environments, and sexual biases in language. A theme of the report is that women's underrepresentation is not primarily due to direct discrimination but to subconscious behavior that perpetuates the status quo.

Compositions in life science data

The aim of this talk is to convince the reader that there are a lot of interesting statistical problems in presentday life science data analysis which seem ultimately connected with compositional statistics. Key words: SAGE, cDNA microarrays, (1D-)NMR, virus quasispecies

Microcalcification evaluation in computer assisted diagnosis for digital mammography

In order to develop applications for z;isual interpretation of medical images, the early detection and evaluation of microcalcifications in digital mammograms is verg important since their presence is often associated with a high incidence of breast cancers. Accurate classification into benign and malignant groups would help improve diagnostic sensitivity as well as reduce the number of unnecessa y biopsies. The challenge here is the selection of the useful features to distinguish benign from malignant micro calcifications. Our purpose in this work is to analyse a microcalcification evaluation method based on a set of shapebased features extracted from the digitised mammography. The segmentation of the microcalcifications is performed using a fixed-tolerance region growing method to extract boundaries of calcifications with manually selected seed pixels. Taking into account that shapes and sizes of clustered microcalcifications have been associated with a high risk of carcinoma based on digerent subjective measures, such as whether or not the calcifications are irregular, linear, vermiform, branched, rounded or ring like, our efforts were addressed to obtain a feature set related to the shape. The identification of the pammeters concerning the malignant character of the microcalcifications was performed on a set of 146 mammograms with their real diagnosis known in advance from biopsies. This allowed identifying the following shape-based parameters as the relevant ones: Number of clusters, Number of holes, Area, Feret elongation, Roughness, and Elongation. Further experiments on a set of 70 new mammogmms showed that the performance of the classification scheme is close to the mean performance of three expert radiologists, which allows to consider the proposed method for assisting the diagnosis and encourages to continue the investigation in the sense of adding new features not only related to the shape

Prevalence and factors associated with dysmenorrheal in health science students

Introduction: Dysmenorrhea has a prevalence between 60 and 93%. Different factors have been associated with it, such as age at menarche, body mass index, exercise, smoking and maternal history of dysmenorrhea, among others. Materials and methods: A cross-sectional study was conducted, based on an anonymous survey applied to a random sample of 127 women from the school of medicine and psychology at the Universidad Del Rosario. Results: The prevalence of  dysmenorrhea was 73%. 67% of participants presenting with menstrual pain, reported having taken pain relief medication (66.7% self medicated). 32.5% of respondents with dysmenorrhea were absent from their academic or social work, with a percentage of school absenteeism due to pain of 74.5% in at least one day. The risk of dysmenorrhoea was 2.36 times higher in women who had mothers with this history (OR = 2.36, 95% CI 1.03 to 5.40). No associations with other factors were found. Conclusions: Dysmenorrhea is a disease with a high prevalence and significant impact on school absenteeism. Maternal history of dysmenorrhea was the only factor positively associated in this study.

Meeting the standards in secondary science : a guide to the ITT NC.

Todos los estudiantes en período de formación docente deben demostrar ciertas aptitudes y conocimientos antes de alcanzar la categoría de profesor cualificado. Aquí se abordan las normas específicas que rigen estas competencias relacionadas con la enseñanza de las ciencias en la etapa de secundaria. A lo largo de sus capítulos se recogen temas como el aprendizaje y la progresión de los alumnos en la educación científica, el desarrollo de habilidades científicas fundamentales, la ciencia y las tecnologías de la información y la comunicación (TIC) y, por último, el desarrollo profesional de los docentes.
