The Effectiveness of Cognitive and Behavioural Treatment of Chronic Pain in the Elderly: A Quantitative Review

This study provides a meta-analytic review of cognitive and behavioural interventions for chronic pain in the elderly, focusing on treatment effectiveness. Included in the analysis are studies in which a comparison was made either to a control condition or to pre-treatment. A total of 12 outcome studies published or reported between January 1975 and March 2008, were identified involving participants 60 years and above and providing 16 separate treatment interventions. The analysis indicated that cognitive and behavioural interventions were effective on self-reported pain experience, yielding an overall effect size of 0.47. However, there were no significant effects of cognitive and behavioural treatment on symptoms of depression, physical functioning and medication use. Methodological issues concerning design, outcome measures and treatment are discussed and recommendations for future studies are outlined.     

The Factor Structure of Cognitive Functioning in Cognitively Healthy Participants: a Meta-Analysis and Meta-Analysis of Individual Participant Data

Neuropsychology Review - Many neuropsychologists are of the opinion that the multitude of cognitive tests may be grouped into a much smaller number of cognitive domains. However, there is little...     

Feminist Bioethics: Where We've Been, Where We's Going

The primary contribution of feminism to bioethics is to note how imbalances of power in the sex-gender system play themselves out in medical practice and in the theory surrounding that practice. I trace the ten-year history of feminist approaches to bioethics, arguing that while feminists have usefully critiqued medicine's biases in favor of men, they have unmasked sexism primarily in the arena of women's reproductive health, leaving other areas of health care sorely in need of feminist scrutiny. I note as well that feminist bioethicists have contributed very little to bioethical theory. In the second part of the paper I suggest two future directions for feminist bioethics. The first is to expand its critique of gender bias beyond reproductive medicine, devoting attention to the same issues raised by advances in biomedical technology as are taken up by mainstream bioethicists. The second is to develop bioethical theory that is more responsive than are mainstream moral theories to the social practices that subordinate women and minority groups.     

Age-related changes in decision making: comparing informed and noninformed situations

Advantageous decision making progressively develops into early adulthood, most specifically in complex and motivationally salient decision situations in which direct feedback on gains and losses is provided (Figner & Weber, 2011). However, the factors that underlie this developmental improvement in decision making are still not well understood. The current study therefore investigates 2 potential factors, long-term memory and working memory, by assigning a large developmental sample (7-29 years of age) to a condition with either high or low demands on long-term and working memory. The first condition featured an age-adapted version of the Iowa Gambling Task (IGT; Bechara, Damasio, Damasio, & Anderson, 1994; i.e., a noninformed situation), whereas the second condition provided an external store where explicit information on gains, losses, and probabilities per choice option was presented (i.e., an informed situation). Consistent with previous developmental IGT studies, children up to age 12 did not learn to prefer advantageous options in the noninformed condition. In contrast, all age groups learned to prefer the advantageous options in the informed conditions, although a slight developmental increase in advantageous decision making remained. These results indicate that lowering dependence on long-term and working memory improves children's advantageous decision making. The results additionally suggest that other factors, like inhibitory control processes, may play an additional role in the development of advantageous decision making.     

Implicit visual learning and the expression of learning

Although the existence of implicit motor learning is now widely accepted, the findings concerning perceptual implicit learning are ambiguous. Some researchers have observed perceptual learning whereas other authors have not. The review of the literature provides different reasons to explain this ambiguous picture, such as differences in the underlying learning processes, selective attention, or differences in the difficulty to express this knowledge. In three experiments, we investigated implicit visual learning within the original serial reaction time task. We used different response devices (keyboard vs. mouse) in order to manipulate selective attention towards response dimensions. Results showed that visual and motor sequence learning differed in terms of RT-benefits, but not in terms of the amount of knowledge assessed after training. Furthermore, visual sequence learning was modulated by selective attention. However, the findings of all three experiments suggest that selective attention did not alter implicit but rather explicit learning processes.     

A bath-mitzvah feast

We are in a red room in a restaurant which has as its decor the Middle Ages. We are seated at a U-shaped table, and we are here to help a young girl celebrate her passage into womanhood. This is no religious ceremony, but a simple spiritual event. No priest, no rabbi is present, only women. All of us are anxious, anticipating what is to come. The girl's mother says a few words about a vision she had had of an inhibition. In it, she said, she saw a group of women seated in a circle around a fire. The drums urged the participants to dance. Amid the stamping of feet around the fire, a young girl comes into the circle and is welcomed by the older women of the tribe. Thus the girl becomes a woman in the community.

Then the young daughter stands up and begins to speak shyly of her nature spirit. She tells us of how she has sought for evidence of God in churches and thus far has only found some contact with Him in nature, alone in a field or on a hilltop.

After that the mother invited the guests to share in helping her daughter “become a woman in the tribe.” Here is how two of the women shared the event.—G.F.     

Impact of Immigration on Economic Growth in Canada and in its Smaller Provinces

This paper evaluates the potential impact of education levels of immigrants and Canadian-born on economic growth in Canada and its smaller provinces by using data for the period 2006–2013. We specify a production function in which levels of educational attainments of immigrants and Canadian-born workers are entered separately. Feasible generalized least square (FGLS) method is applied to estimate the production function separately for all immigrants, and also for established immigrants (those who have been in Canada for 10 years or longer). The results show that all educational levels of immigrants have positive and statistically significant effects on economic growth. A similar conclusion applies to Canadian-born workers, although the impacts of their university degree holders is lower than that of immigrant university degree holders. Both immigrant and Canadian-born workers have smaller effects on economic growth in smaller provinces, which have attracted larger numbers of immigrants in recent years. The results also show that the economic growth effects are similar for all and established immigrants. Although these results are consistent with previous findings on discounting of immigrants’ educational credentials, more data are needed to strengthen their validity. We also suggest that the higher economic growth impact of immigrant university degree holders than that of Canadian-born is indicative of greater social returns to higher education resulting from increased diversity of population which in turn, as some previous studies suggest, can result in increased technological innovation, new ideas, and production of a wide variety of goods and services.
