Normalización y accesibilidad

El objetivo de este documento es analizar la normativa relacionada con la accesibilidad; tanto la normativa legal, de obligado cumplimiento, como las normas técnicas o estándares desarrollados por las organizaciones nacionales o internacionales de normalización, cuyo cumplimiento no es obligatorio. En las últimas décadas ha habido un amplio desarrollo en estos dos tipos de normativas, sin embargo, persiste el reto de conseguir que los presupuestos estipulados en ellas tengan un beneficio real en las personas con discapacidad, porque se cumplan las leyes de forma efectiva y porque los productos contemplen los requisitos de un diseño para todos. En «Normalización y accesibilidad» se ofrece una información detallada sobre estos temas, para contribuir a un mayor conocimiento y fomentar la utilización de la normativa como una herramienta de mejora en la accesibilidad de los servicios y productos

Severe plastic deformation of Al–Zn alloys

In this work, the R&D work mainly focused on the mechanical and microstructural analysis of severe plastic deformation (SPD) of Al–Zn alloys and the development of microstructure–based models to explain the observed behaviors is presented. Evolution of the microstructure and mechanical properties of Al–30wt% Zn alloy after the SPD by the high–pressure torsion (HPT) has been investigated in detail regarding the increasing amount of deformation. SPD leads to the gradual grain refinement and decomposition of the Al–based supersaturated solid solution. The initial microstructure of the Al–30wt% Zn alloy contains Al and Zn phases with grains sizes respectively of 15 and 1 micron. The SPD in compression leads to a gradual decrease of the Al and Zn phase grain sizes down to 4 microns and 252 nm, respectively, until a plastic strain of 0.25 is reached. At the same time, the average size of the Zn particles in the bulk of the Al grains increases from 20 to 60 nm and that of the Zn precipitates near or at the grain boundaries increases as well. This microstructure transformation is accompanied at the macroscopic scale by a marked softening of the alloy. The SPD produced by HPT is conducted up to a shear strain of 314. The final Al and Zn grains refine down to the nanoscale with sizes of 370 nm and 170 nm, respectively. As a result of HPT, the Zn–rich (Al) supersaturated solid solution decomposes completely and reaches the equilibrium state corresponding to room temperature and its leads to the material softening. A new microstructure–based model is proposed to describe the softening process occurring during the compression of the supersaturated Al–30wt% Zn alloy. The model successfully describes the above–mentioned phenomena based on a new evolution law expressing the dislocation mean free path as a function of the plastic strain. The softening of the material behavior during HPT process is captured very well by the proposed model that takes into consideration the effects of solid solution hardening and its decomposition, Orowan looping and dislocation density evolution. In particular, it is demonstrated that the softening process that occurs during HPT can be attributed mainly to the decomposition of the supersaturated solid solution and, in a lesser extent, to the evolution of the dislocation mean free path with plastic strain.

As literaturas contemporâneas espanhola e portuguesa como espaços culturais de memória histórico-política

Nesta dissertação analisamos a forma como quatro obras literárias contemporâneas se podem constituir como espaço cultural de memória histórico-política das décadas que em Portugal e Espanha se seguiram à implantação dos regimes democráticos. O trabalho incide na análise de Os Memoráveis, de Lídia Jorge, Novembro, de Jaime Nogueira Pinto, Las leyes de la frontera, de Javier Cercas, e Romanticismo, de Manuel Longares. Procede-se à análise comparativa dos quatro romances e à forma como cada um problematiza dois períodos fundamentais da história recente dos dois países. São também tratadas as questões relacionadas com o diálogo entre o conhecimento histórico e literário, o lado fictício e imaginário da história e a contribuição da memória para a reconstrução dos processos históricos. Procura-se também entender de que forma a literatura se constitui como uma forma de reflexão catártica e crítica, como suscita a problematização do momento presente, e que marcas pessoais e/ou autobiográficas os autores deixam transparecer nas suas obras.

The influence of physical attractiveness and gender on perceived competence of sportscasters

The media tends to represent female athletes as women first and athletes second (Koivula, 1 999). The present study investigated whether this same trend was present for female sportscasters, using a self-presentational framework. Self-presentation is the process by which people try to control how others see them (Leary, 1995). One factor that may influence the type of image they try to project is their roles held in society, including gender roles. The gender roles for a man include dominance, assertiveness, and masculinity, while the gender roles for a woman include nurturer, femininity, and attractiveness (Deaux & Major, 1 987). By contrast, sports broadcasters are expected to be knowledgeable, assertive, and competent. Research suggests that female sports broadcasters are seen as less competent and less persuasive than male sports broadcasters (Mitrook & Dorr, 2001; Ordman & Zillmann, 1994, Toro, 2005). One reason for this difference may be that the gender roles for a man are much more similar to those of a sportscaster, compared to those of a woman. Thus, there may be a conflict between the two roles for women. The present study investigated whether the gender and perceived attractiveness of sportscasters influenced the audience's perceptions of the level of competence that a sportscaster demonstrates. Two hundred and four male (n =75) and female (n =129) undergraduate students were recruited from a southern Ontario university to participate in the study. The average age of the male participants was 21 .23 years {SD =1 .60), and the average age for female participants was 20.67 years {SD = 1 .31). The age range for all participants was from 19 to 30 years {M = 20.87 years, SD = 1 .45). Af^er providing informed consent, participants randomly received one of four possible questionnaire packages. The participants answered the demographic questionnaire, and then proceeded to view the picture and read the script of a sports newscast. Next, based on the picture and script, the participants answered the competence questionnaire, assessing the general, sport specific, and overall competence of the sportscaster. Once participants had finished, they returned the package to the researcher and were thanked for their time. Data was analyzed using an ANOVA to determine if general sport competence differs with respect to gender and attractiveness of the sportscaster. Overall, the ANOVA was non-significant (p > .05), indicating no differences on the dependent variable based on gender (F (3, 194) = .631, p = .426), attractiveness (F (3, 194) = .070, p = .791), or the interaction of the two {F (3, 194) = .043,/? = .836). Although none of the study hypotheses were supported, the study provided some insight to the perceived competence of female sportscasters. It is possible that female sportscasters are now seen as competent in the area of sports. Sample characteristics could also have influenced these results; the participants in the current study were primarily physical education and kinesiology students, who had experience participating in physical activity with both men and women. Future research should investigate this issue further by using a video sportscast. It is possible that delivery characteristics such as voice quality or eye contact may also impact perceptions of sportscasters.

James J. Campbell [right], director of the Chapman College Residence Education Center at the El Toro Marine Corps Air Station, discusses the college's new science scholarship program with Dr. Arthur Flint, chairman of the Chapman Division of Natural Sciences, in front of the new science center, Hashinger Hall, Chapman College, 346 N. Center Street, Orange, California. The late Dr. Edward H. Hashinger, former trustee and past chairman of the board is the man whose name has graced the walls of this building since 1969. The Hashinger Science Center (3 floors, 65,364 sq.ft.) houses all science departments including biology, natural and applied sciences, environmental and chemical sciences, food science and nutrition, kinesiology and physical therapy.
