Cognitive control of involuntary distraction by deviant sounds.

It is well established that a task-irrelevant sound (deviant sound) departing from an otherwise repetitive sequence of sounds (standard sounds) elicits an involuntary capture of attention and orienting response toward the deviant stimulus, resulting in the lengthening of response times in an ongoing task. Some have argued that this type of distraction can be reduced by cognitive control when visual stimuli cue the presentation of the deviant and standard sounds. We compared this account with an alternative explanation, namely, that cues may reduce distraction because cue processing depletes attentional resources from the orienting response to the deviant sound.

This paper discusses the transformations undergone by Mexican families in the 20th century and how some internal dynamics unfolded with the increase in the individual life expectancy and the presence of functional incapacities in the older family members. It reflects on social and demographic changes in the families and on support and care strategies directed at elderly people who are ill and have functional limitations, based on calculations obtained from the Encuesta Nacional sobre Salud y Envejecimiento (2001). Although there are efforts on the part of health institutions and family arrangements to deal with this situation, this paper shows the strength and the weakness of the social protection systems regarding care and support for aged people with functional incapacity.

Turning points and advanced family cycles: aging effect in Mexican homes.

Aging in Mexico is a process with several effects in the families and homes. However, the presence of older members in Mexican families has been scarcely analyzed. In this paper we reflect on the experiences of homes with advanced life cycles when turning points happen, such as widowhood, retirement, empty nest stage and when chronic diseases appear, as well as caring processes and family and social networks weakening, and social and institutional support diminution.

Primary bone lymphoma.

Primary bone lymphoma is a rare condition which represents a low percentage of both the malignant primary bone tumours and the non-Hodgkin extranodal lymphoma. This explains the lack of publications, lines of investigations, and specific diagnostic and treatment protocols. In the following article we will carry out a revision of the existing literature on this rare subject, using as argument a clinical case of left femoral location stage IE treated with CHOP chemotherapy and radiotherapy.

[Mexico and the State of Guanajuato: Intergenerational transfers to the elderly].

In Mexico, there is a range of formal and informal transfers to help older adults. This paper analyses national trends and the results of a study focused on the federal entity of Guanajuato. The distribution of the support provided confirms that the transfers made by the social security system have an urban bias and that formal transfers from the federal government are oriented to the least urban areas, and especially rural areas.
