A prenatal intervention designed to prevent the onset of major depressive episodes (MDEs) during pregnancy and postpartum was pilot tested at a public sector women’s clinic. The Mamás y Bebés/Mothers and Babies Course is an intervention developed in Spanish and English that uses a cognitive-behavioral mood management framework, and incorporates social learning concepts, attachment theory, and socio-cultural issues. The four goals of this project were to develop the intervention, assess its acceptability, test the feasibility of conducting a randomized trial with public sector patients, and obtain estimates of its effect size. Forty-one pregnant women at high risk for developing MDEs were randomized to the Mothers and Babies Course (n = 21) or a comparison condition (n = 20). Assessments occurred during pregnancy and at 1, 3, 6, and 12 months postpartum. Differences in terms of depression symptom levels or incidence of MDEs between the two groups did not reach statistical significance in this pilot trial. However, the MDE incidence rates of 14% for the intervention condition versus 25% for the comparison condition represent a small effect size (h = 0.28) that will be further examined in a larger scale study. The intervention was well received by the participants and implementation of a randomized trial appeared quite feasible as indicated by our follow-up rate of 91% at 12 months. Implications for the continuing development of preventive interventions for perinatal depression are discussed.  相似文献

This exploratory mixed-method study focussed on the experiences of internationally trained engineers in looking for and finding suitable employment in Canada. An online survey was conducted with 309 internationally trained engineers. The internationally trained engineers used a range of job search strategies to look for suitable employment in the engineering field, often with little success. Those respondents who had secured jobs in the engineering profession were significantly more likely to have been referred by another employer (p?=?0.05) and less likely to have placed or responded to an advertisement in the newspaper (p?<?0.05) than those who did not hold jobs in the engineering profession. No significant differences were seen between these two groups regarding other job search strategies used. In-depth qualitative interviews were conducted with 20 of the survey respondents, and this paper details the diverse strategies used by these participants to find suitable employment. The findings of the study emphasise the role of systemic-level barriers in the job search experience of internationally trained engineers.  相似文献

Two eye tracking experiments show that, for near launch sites, the eyes land nearer to the beginning of words with orthographically irregular than with regular initial letter sequences. In addition, the characteristics of words, at least at the level of orthography, influence the direction and length of within-word saccades. Importantly, these effects hold both for lower case and for visually less distinctive upper case text. Furthermore, contrary to previous evidence (Tinker & Paterson, 1939), there is little effect of type case on reading times. Additional analyses of oculomotor behaviour suggest that there is an inverted optimal viewing position for single fixation durations on words. Both the supplementary analyses and the effects of orthography on fixation positions are relevant to current models of eye movements in reading.  相似文献

In three experiments rats were given short or long preexposure (4 or 10 sessions) to two compound flavours, AX and BX, according to an intermixed or a blocked schedule. Following preexposure, aversion conditioning trials were given with AX as the conditioned stimulus (CS). In Experiments 1 and 2, retardation and summation tests were then carried out to assess the inhibitory properties of B (an Espinet procedure). In Experiment 3, test trials evaluated generalization from AX to BX (the standard perceptual learning procedure). The results showed that B performed as an inhibitor of the unconditioned stimulus (US; an Espinet effect) only after long intermixed preexposure, whereas a reliable perceptual learning effect was observed both after short and after long preeexposure. The observation that B had no detectable inhibitory properties after short preexposure casts doubt on the suggestion that inhibitory learning is responsible for perceptual learning after brief exposure to AX and BX.  相似文献

A comparison of the effects of wavy rolling and cold rolling on microstructure variation, phase evolution, tensile and magnetic properties of a thin coil of Fe-18.47Cr-8.10Ni-0.94Mn austenitic stainless steel was made at room temperature. Wavy rolling led to strengthening with no change in magnetic property and thickness, unlike the conventional cold rolling that changed all these properties by deformation induced martensitic transformation, in addition to substructure evolution. The yield strength of 413 MPa and magnetic saturation 3.7 emu/g under mill-annealed condition increased, respectively, to 1208 MPa and 11.8 emu/g, upon four cycles of wavy rolling. While the maximum yield strength of 1790 MPa could be achieved by combining this stage of four cycles of wavy rolling with subsequent 50% conventional cold rolling, the magnetic saturation increased to 73.3 emu/g by deformation induced martensitic transformation caused by the latter.  相似文献
