OBJECTIVE: The Resources for Health trial evaluates a social-ecologically based lifestyle (physical activity and diet) intervention targeting low-income, largely Spanish-speaking patients with multiple chronic conditions. DESIGN: A randomized controlled trial was conducted with 200 patients recruited from an urban community health center and assigned to intervention and usual care conditions. Intervention involved 2 face-to-face, self-management support and community linkage sessions with a health educator, 3 follow-up phone calls, and 3 tailored newsletters. MAIN OUTCOME MEASURES: Primary outcomes measured at 6-months were changes in dietary behavior and physical activity. Changes in multilevel support for healthy living were evaluated as a secondary outcome. RESULTS: After adjustment for age, sex, language, and number of chronic conditions, significant intervention effects were observed for dietary behavior and multilevel support for healthy lifestyles but not for physical activity. CONCLUSION: The Resources for Health intervention provides an effective and practical model for improving health behavior among low-income, Spanish-speaking patients with multiple chronic conditions. 相似文献
The effects of pregnancy on hiring decisions during employment interviews are examined in a United States sample of 210 undergraduate
business school students at a Midwestern university. A pregnant applicant was compared to a non-pregnant applicant with identical
credentials and interview performance to explore any differences in interviewer ratings of qualifications and hiring by having
participants view videotaped interviews. Results show that in spite of being viewed as equally qualified and well-suited for
the job, the pregnant applicant received significantly lower hiring recommendation ratings. The pregnant applicant was also
rated as more likely to need time off, miss work and quit compared to the non-pregnant applicant, indicating a concern about
absenteeism regarding the pregnant applicant. 相似文献
Perceived heaviness has been shown to be specific to an object’s rotational inertia (I ), its resistance to rotational acceleration.
According to the kinematic specification of dynamics (KSD) principle, we hypothesized that I is optically specified by rotational
kinematics. Using virtual depictions of wielded objects, we investigated whether the visually detected rotational kinematics
of wielded objects would influence perceived heaviness in a manner consistent with the inertial model of heaviness perception.
We scaled the virtual object’s movement so that it rotated more or less than its wielded counterpart, specifying lower and
higher I, respectively. Perceived heaviness was inversely related to the rotational scaling factor, consistent with a KSD
interpretation of the inertial model. 相似文献
A large body of literature describes subtle oral motor differences among people who stutter, which are not typical of other speakers. The purpose of this report was to propose that oral motor discoordination (OMD) can be assessed and treated, and that such treatment may be useful prior to targeting perceived stuttering behaviors.
Oral motor coordination (correct voicing, smooth coarticulation, proper sequencing, and age appropriate rate of production of syllables) was assessed using an Oral Motor Assessment Scale. An oral motor training program was described that improved OMD 78% after 14 hours of training in nine children. Stuttering was improved 62% by the training, although it was not specifically targeted. This report proposes that improvement in OMD and reduction of stuttering may be reciprocal (i.e., treatment of one may produce improvement in the other as a byproduct). It may be that OMD is among the physiologic features that can cause post-treatment fluency to be “tenuous.” Its inclusion in treatment programs may improve maintenance and naturalness of fluency. 相似文献
It was proposed that prediction hypotheses do not emerge full blown in the repertoire of the young child. Instead, the component units out of which predictions are consolidated (win-stay, lose-shift) are acquired independently and at different rates. The young child's behavior is at first dominated by response sets in which the win and lose components involve the same action (win-stay, lose-stay or win-shift, lose-shift). The components of response sets must be separated and coordinated with task-relevant information before appropriate components are consolidated to yield prediction hypotheses. A combination of learning-set and blank-trial procedures was used to evaluate this conception with preschoolers (mean CA = 4:1) and second graders (mean CA = 7:6). Results revealed that children of both age levels exhibited response patterns that corresponded to hypotheses in most of their probes (.89 to. 98). The striking finding was the relative weakness of win-stay on object cues at the outset of acquisition, particularly among the younger children. In contrast. lose-shift object was strong from the outset among children of both age levels. Once the two components (win-stay object, lose-shift object) were consolidated, the resulting scheme was durable, in that transfer to more complex problems was nearly perfect. Children who did not achieve criterion (in 70 problems) failed because they exhibited mostly position hypotheses and/or because the strength of win-stay object remained weak throughout all sessions. 相似文献
