Scholars of Cuba have long linked Afro-Cubans' fate to the revolutionary government. As the government's influence on people's daily lives has declined over the past decade, the question arises of whether Afro-Cubans have sustained the gains they achieved in the revolution's first 30 years. This article uses survey data, collected in December 2000 from 334 Cuban families in Havana, to assess the impact of the post-1993 economic reforms on rising racial inequality in Cuba. It asks whether racial inequities occur in accessing dollars through state employment, self-employment, or remittances, and whether educational gains are tied to higher income. Results indicate that the structural means through which racial discrimination was once virtually eliminated through equal access to education and employment, and through which income levels became equalized according to educational level regardless of racial group, has lost its equalizing force in contemporary Cuba. 相似文献

Women Representatives Acting for Women: Sex and the Signing of Early Day Motions in the 1997 British Parliament 总被引:1,自引:0,他引:1
The return of 101 Labour women MPs in 1997 generated an expectation that their presence would enhance women's substantive representation. And many of Labour's new women MPs claim to have acted for women since their election. Yet demonstrating the difference that MPs make is not easy. Much of what goes on in the chamber of the Commons reflects party identity, and much of what goes on elsewhere in parliament is hidden. Studying sex differences in the signing of early day motions (EDMs) provides one way of testing whether Labour's women MPs are acting for women. Analysis of all the EDMs in the 1997 parliament, some 5,000 motions, establishes that they are more likely than Labour's men to sign 'women's' and especially feminist 'women's' EDMs. There is clear evidence of behavioural differences between Labour's women and men MPs, strengthening arguments that women's political presence is important because of the substantive difference they can make. 相似文献

The Adolescent Attachment Questionnaire (AAQ), a brief questionnaire to assess attachment characteristics in adolescents, was developed and validated in a large normative sample (n = 691) and a sample of 133 adolescents in psychiatric treatment. The AAQ is a self-report questionnaire consisting of 3 scales of 3 statements each, with Likert-type responses from strongly disagree to strongly agree. The Availability scale assesses the adolescent's confidence in the availability and responsiveness of the attachment figure. TheGoal-Corrected Partnershipscale assesses the extent to which the adolescent considers and is empathetic to the needs and feelings of the attachment figure. The Angry Distress scale taps the amount of anger in the adolescent–parent relationship. All scales demonstrate satisfactory internal reliability and agreement between scores for adolescents (n = 91) from the normative sample who completed the AAQ twice. Adolescents in the clinical sample also completed the Adult Attachment Interview (AAI); the AAQ demonstrated high convergent validity with the AAI. 相似文献

1,2-Indandione has been used to develop fluorescent fingerprints on porous materials such as paper. The compound reacts with amino acid residues to produce highly fluorescent fingerprint ridges. An optimized formulation and treatment protocol for using the reagent is presented here. The reagent is applied as a solution in HFE7100 containing acetic acid and ethyl acetate. Treated articles are heated at 100 degrees C for 10 min at ambient humidity and stored in the dark before recording the fingerprints using fluorescence photography or digital imaging. Photodecomposition of the fluorescent fingerprints has been observed. Storage in the dark reduces degradation, extending the lifetime of the fingerprints. Other chemical methods to stabilize the fingerprints proved unsuccessful. Comparisons of the performance of 1,2-indandione with DFO in CFC113 performed on a limited range of substrates indicated that the reagent might be an effective method for the development of latent fingerprints despite the new reagent producing less intense fluorescence. 相似文献

Several variant alleles of the HumD21S11 locus have only been reported in Australasian population samples. Fifteen such alleles were observed in Caucasian and Australian Aborigine sub-population databases compiled from residents of the state of Western Australia. Each variant was sequenced to authenticate the allelic designation and determine the structural conformation. Nine novel structural variants are described. The structure of the repeat region of these rare alleles combined with the STR designation brings aspects of the HumD21S11 nomenclature guidelines into question, in particular the designation of common incomplete repeats (or "0.2's"). The conformation of the sequences provides evidence in support of a genetic relationship between the Australian Aborigine and the Papuan people. 相似文献

This study investigated whether parent–teen disagreement in reports of sexual discussions is due to methodological factors. Forty-four mothers and their 12- to 15-year-old daughters (n = 18) and sons (n = 26) completed parallel questionnaires including measures of communication about 18 different sexual topics during the teen's entire life and during the past year. Analyses examined whether congruence rates were influenced by the use of global as compared to specific items, assessment of conversations during the teen's entire life as compared to the past year, and use of forced-choice as opposed to continuous-response categories. Taken as a whole, results support the notion that methodological limitations are partly responsible for lack of congruence in parent–teen reports. Suggestions for methodological improvements in future research are discussed. 相似文献
