The influence of collaboration on program outcomes: the Colorado Nurse-Family Partnership

Though collaboration is often required in community initiatives, little evidence documents relationships between collaboration and program success. The authors contend that clarification of the construct collaboration is necessary for investigating its contribution to the success of community initiatives. After respecifying collaboration, they present a study of a multisite program that involved varying degrees of collaboration in the 16 communities adopting a nurse home visitation program. The authors employ hierarchical linear modeling (HLM) to test the predictive power of individual participant characteristics and examine the increased accuracy of predictions from a second level model of site qualities-specifically, features of the collaborative process associated with different sites. The first-level model predicted approximately 10% of the variance in attrition, or dropout, of program clients. The second-level model accounted for an additional 28% of the variance in attrition. A theory of commitment transfer is offered as a first explanation of this result.     

Meditation lowers stress and supports forgiveness among college students: a randomized controlled trial

OBJECTIVE AND PARTICIPANTS: The authors evaluated the effects on stress, rumination, forgiveness, and hope of two 8-week, 90-min/wk training programs for college undergraduates in meditation-based stress-management tools. METHODS: After a pretest, the authors randomly allocated college undergraduates to training in mindfulness-based stress reduction (MBSR; n = 15), Easwaran's Eight-Point Program (EPP; n = 14), or wait-list control (n = 15). The authors gathered pretest, posttest, and 8-week follow-up data on self-report outcome measures. RESULTS: The authors observed no post-treatment differences between MBSR and EPP or between posttest and 8-week follow-up (p > .10). Compared with controls, treated participants (n = 29) demonstrated significant benefits for stress (p < .05, Cohen's d = -.45) and forgiveness (p < .05, d = .34) and marginal benefits for rumination (p < .10, d = -.34). CONCLUSIONS: Evidence suggests that meditation-based stress-management practices reduce stress and enhance forgiveness among college undergraduates. Such programs merit further study as potential health-promotion tools for college populations.     

请再说一遍“我爱你”

【正】请说了一遍,再向我说一遍,说"我爱你"即使那样一遍遍重复,你会把它看成一支"布谷鸟的歌曲";可是记着,在那青山和绿林间,那山谷和田野中,纵使清新的春天披着全身绿装降临、也不算完美无缺,要是她缺少了那串布谷鸟的音节。爱,四周那么黑暗,耳边只听见惊悸的心声,处于那痛苦的不安中,我嚷道:"再说一遍:我爱你!"谁嫌太多的...     

Toward a ‘paideia of the soul’: education to enrich America’s multicultural democracy

What role might education play in the reinvigoration of a robust American democracy? We argue that common understandings of democracy, citizenship, and democratic education are too anemic to right the political inequalities and stagnancies that have deadened American democracy. Instead, we look to notions of paideia and an educated, enlightened citizenry to shape a multicultural democratic education. Multicultural democratic education cultivates the full and flourishing lives and minds of all citizens in American democracy rather than focusing on narrow preparation for voting. It does this through the practice of critical and authentic caring, the cultivation of community across difference, the connection to a global context, and the opportunity for social action. Most importantly, multicultural democratic education takes as its starting point equity and justice in a pluralistic society by committing to the cultivation of the minds and intellects of all students – in stark contrast to the unequal and mind-numbing education that most marginalized and minority students receive.     

Mapping the Timing,Pace, and Scale of the Fertility Transition in Brazil

Between 1960 and 2000, fertility fell sharply in Brazil, but this transition was unevenly distributed in space and time. Using Bayesian spatial statistical methods and microdata from five censuses, we develop and apply a procedure for fitting logistic curves to the fertility transitions in more than 500 small regions of Brazil over this 40‐year period. Doing so enables us to map the main features of the Brazilian fertility transition in considerable detail. We detect early declines in some regions of the country and document large differences between early and late transitions in regard to both the initial level of fertility and the speed of the transition. We also use our results to test hypotheses regarding changes in the level of development at the onset of the fertility transition and identify a temporary stall in the Brazilian transition that occurred in the late 1990s.

Comparison of some common ratio estimators using pitman measure of nearness

In this article we compare some common ratio estimators for estimating the population total of a given characteristic. The sampling schemes considered are simple random sampling (S.R.S.) and S.R.S.under stratification. The comparisons are made using the Pitman Nearness criterion under the model-based approach. The error term is assumed normal with mean zero and variance σg(x). The function g(x) is a known function of the auxiliary variable x. Special interest is on the cases of g(x) =l and x. The result is found the same as that using MSE criterion, although the PN is very different from the MSE intrinsically.     

Migration bias in indirect estimates of regional childhood mortality levels

Demographers often use Brass‐style indirect methods to obtain childhood mortality estimates for regions within developing countries. Regional populations are not closed to migration, however, and mortality reports of women resident in a certain region on the survey date may contain information on events and exposure that occurred elsewhere as the mother migrated. Including this “imported”; mortality information may cause significant bias in regional estimates. In this paper the authors: (1) investigate the possible magnitude of migration bias using a multiregional simulation model, (2) propose a modification to standard methods which should reduce bias in many circumstances, and (3) apply the modified technique to data from Brazil's 1980 Census. We find that migration bias can indeed be significant, and that in the specific case of São Paulo state, imported mortality information may result in overestimates of local mortality levels of 10–15% when using Brass‐style methods.     

Role clarity,work overload and organizational support: Multilevel evidence of the importance of support

The present study extended the demands-control-support model used in occupational stress research in two ways. First, it hypothesized that role clarity (i.e. role ambiguity), like control, would moderate the relationship between demands and psychological strain. Second, the study assessed support (from leaders) as a macro characteristic of the work-group environment. Data were drawn from a large study of US army soldiers, the study sample consisting of 1786 lower enlisted male soldiers. The inclusion of support as a work-group characteristic lead to a multilevel test of the model. A three-way multilevel interaction among work demands, role clarity and support was observed. As predicted, the relationship between demands and psychological strain was moderated by role clarity; however, this moderating relationship was found only when work-group support was high.
