Ethnicities and social adjustment in Canadian adolescents

Canada is a complex plural society made of groups with multiple ethnic and linguistic origins. It is uncertain whether government support for multiculturalism is reflected in retention of ethnic identities in the majority of the population in the face of both acculturative social forces and publicly expressed political arguments against multiculturalism. The degree to which ethnic identity or identities are retained in young people is explored through secondary analysis of data gathered on some 2,100 Alberta adolescents, with analysis of various kinds of social adjustment that may be linked to expressed ethnic origins or ancestries. Nearly half of the adolescents retained a single ethnic allegiance, with the remainder expressing multiple ethnic identities. Many non-random patterns were found in terms of association of declared ethnic allegiance and variables such as home language; religious affiliation and observance; scholastic achievement; sexual behaviour; alcohol and drug use; family structure; and parental education family discord, and selfesteem. Three groups (South Asian, Chinese, and Spanish and Portuguese) emerged as having strong family systems, conservative social habits and high achievement aspirations. Correlation of variables across ethnic groupings indicated a coherent pattern, with students of German, Polish, and Italian ancestry forming a group; Dutch and Ukrainian-ancestry students another; French, Scots, and Irish-ancestry a further group; and Scandinavian and English-ancestry students another group. The results are promising enough for us to propose that further research on comlex ethnic identities and social behaviours in youth should be undertaken.

Changes in contraceptive method mix in developing countries

CONTEXT: Understanding shifts in contraceptive method mix is key to helping policymakers, program managers and donor agencies meet current contraceptive demand and estimate future needs in developing countries. METHODS: Data from Demographic and Health Surveys, Reproductive Health Surveys and other nationally representative surveys were analyzed to describe trends and shifts in method mix among married women of reproductive age from 1980 to 2005. The analysis included 310 surveys from 104 developing countries. RESULTS: Contraceptive use among married women of reproductive age increased in all regions of the developing world, reaching 66% in Asia and 73% in Latin America and the Caribbean in 2000-2005, though only 22% in Sub- Saharan Africa. The proportion of married contraceptive users relying on the IUD declined from 24% to 20%, and the proportion using the pill fell from 16% to 12%. The share of method mix for injectables rose from 2% to 8%, and climbed from 8% to 26% in Sub-Saharan Africa, while the share for condoms was 5-7%. The overall proportion of users relying on female sterilization ranged from 29% to 39%, reaching 42-43% in Asia and in Latin America and the Caribbean in 2000-2005; on average, the share of all method use accounted for by male sterilization remained below 3% for all periods. Use of traditional methods declined in all regions; the sharpest drop-from 56% to 31% of users-occurred in Sub-Saharan Africa. CONCLUSIONS: To meet the rising demand for modern methods, it is critical that future programmatic efforts provide methods that are both accessible and acceptable to users.     

Jung's “Multicolored Arabesques”: Their Renderings and Intentions in the Pictorial Vocabulary of The Red Book

Paintings say more than what they seemingly show. Jung's pictorial vocabulary as a painter and illustrator is not gratuitous and deserves close study. At first Jung tried various styles, naïve or academic. Then he developed “multicolored arabesques” quite extensively, obviously enjoying drawing and painting virtuoso variations on the theme. These beautiful artistic forms can possibly be analyzed as pictorial representations of the unconscious, of the archetypes and their ever-flowing energies. For such vivid subjects that are impossible to describe or portray in either words or images, Jung, in his precious Red Book, has achieved a creation, by pencil and brush, of a superb array of “good-enough” renderings in images of their psychological reality.     

Do sheep (<Emphasis Type="Italic">Ovis aries</Emphasis>) categorize plant species according to botanical family?

The ability of grazing herbivores to assign food types to categories by relying on certain relevant criteria could considerably reduce cognitive demand and increase their foraging efficiency when selecting among many different plant items. Grasses and legumes differ functionally in vegetation communities as well as in nutritive value. We aimed to determine whether sheep can generalize an aversion they learnt for a grass or a legume species to another species of the same functional type and consequently whether botanical family is a potential level of categorization. Over four successive weeks, 12 lambs were conditioned against either a freshly cut grass (tall fescue—Festuca arundinacea, N = 6) or legume species (sainfoin—Onobrychis viciifolia, N = 6) using a negative post-ingestive stimulus (lithium chloride) on day 1. Preference of all lambs between another grass (cocksfoot—Dactylis glomerata) and another legume (alfalfa—Medicago sativa) was assessed on day 3 by measuring their relative consumptions. Preference for alfalfa progressively became lower for lambs that were conditioned against sainfoin than against tall fescue, indicating that lambs generalized the aversion between species along some perceptual gradient and classed the considered grasses and legumes in distinct categories. Beyond this original result, the question now is to identify which specific plant characteristics or functional traits the animals rely on in order to form categories.     

On coding the position of letters in words: a test of two models

Open-bigram and spatial-coding schemes provide different accounts of how letter position is encoded by the brain during visual word recognition. Open-bigram coding involves an explicit representation of order based on letter pairs, while spatial coding involves a comparison function operating over representations of individual letters. We identify a set of priming conditions (subset primes and reversed interior primes) for which the two types of coding schemes give opposing predictions, hence providing the opportunity for strong scientific inference. Experimental results are consistent with the open-bigram account, and inconsistent with the spatial-coding scheme.     

Confidence and accuracy of lineup selections and rejections: Postdicting rejection accuracy with confidence

Correlation and calibration approaches show meaningful, positive confidence-accuracy relations for witnesses making selections from lineups, but rarely for rejections (Brewer and Wells, 2006, Sauerland and Sporer, 2009). This disparity may reflect the difference between selecting a single photo versus rejecting a set of photos. Participants (N = 101) in two experiments made selections from and rejections of lineups in situations requiring either a single confidence rating about a single face (typical of “choosers”) or a single confidence rating about multiple faces (typical of “nonchoosers”). Mean confidence ratings were significantly higher for accurate versus inaccurate decisions for both selections and rejections when decisions were based on single faces. Single decisions about multiple faces produced no significant difference in confidence between correct and incorrect rejections but a significant difference for selections.
