This article argues that, although effective strategic choices for achieving global development goals need to be based on assessments of the costs and benefits of alternative approaches, existing methods of arriving at such assessments are highly unreliable, in particular deriving from implausible and restrictive assumptions and often depending on data of poor quality, and on the pretence that the future can be adequately known. Such weaknesses can be mitigated, but not easily overcome, without abandoning deeply held technocratic presumptions.  相似文献

The transition from milk to complementary food is a crucial but difficult process, requiring considerable adult sensitivity. We know little about the relationship between maternal feeding behaviors and infant willingness to eat at the onset of complementary feeding (CF), and we know even less about how these patterns might vary across cultures. Thirty‐seven dyads (15 from the UK and 22 from Italy) took part in a longitudinal study, during which mealtimes were video‐recorded 1 week after the onset of CF (Time 1) and at 7 months of infant age (Time 2). The first five minutes of mealtimes were coded for maternal feeding behaviors, for infant willingness to eat, and for synchrony in feeding. Maternal vocal communications (MVCs) and attention‐directing acts (ADAs) during the whole mealtime were also coded. Infant willingness to eat was significantly related to synchrony and co‐eating, suggesting the importance of sensitivity and empathy during feeding as in other parent–infant interactions. The frequency of maternal ADAs varied between nationalities and, contrary to current advice, did not relate negatively to infant willingness to eat. These patterns and variations suggest the need to consider CF as a contextually variable and sensitive foundation for feeding relationships.  相似文献

Small island nations in the South Pacific are facing a serious problem of loss of human capital. The loss of skilled and qualified personnel from the small pool is causing a major setback in terms of providing the technical expertise to forge ahead with reform programs that these economies are undertaking. Fiji's policymakers are increasingly confronting this issue, because the nation has experienced a massive outflow of skilled labor following the political instability in 1987. While there is an outflow of skilled labor, the country is also losing a large amount of financial capital. The extent of the outflow has yet to be measured due to lack of a methodology. This study advances a methodology to measure the loss to the economy arising out of human capital loss in a small island economy.  相似文献

Several survey studies have found that internal migrants report lower levels of happiness than locals, even after accounting for socio-economic factors. Traditional global self-ratings reveal that the migrantlocal happiness-gap is also present in the data we present. The reasons for the migrantlocal happiness-gap are as yet unclear. This paper aims to open this ‘black box’ by exploring the role of daily activities among a population that has generally been overlooked despite their high migration frequency: young adults. An innovative smartphone application is used that combines two techniques for multiple moment assessment: the experience sampling method and the day reconstruction method. Based on the application data, we examine whether internal migrants spend their time differently than locals and in which situations they feel noticeably less happy than locals. The data reveal that internal migrants distribute less time to happiness-producing activities such as active leisure, social drinking/parties, and activities outside home/work/transit. Internal migrants feel less happy than locals when spending time with friends and while eating. Possible explanations focusing on the role of social capital are discussed. Further analyses reveal that daily life experiences greatly enhance the explanation of the migrant–local happiness-gap. This paper demonstrates the potential value of real-time data and phone applications in solving happiness puzzles.  相似文献

In longitudinal studies of biomarkers, an outcome of interest is the time at which a biomarker reaches a particular threshold. The CD4 count is a widely used marker of human immunodeficiency virus progression. Because of the inherent variability of this marker, a single CD4 count below a relevant threshold should be interpreted with caution. Several studies have applied persistence criteria, designating the outcome as the time to the occurrence of two consecutive measurements less than the threshold. In this paper, we propose a method to estimate the time to attainment of two consecutive CD4 counts less than a meaningful threshold, which takes into account the patient‐specific trajectory and measurement error. An expression for the expected time to threshold is presented, which is a function of the fixed effects, random effects and residual variance. We present an application to human immunodeficiency virus‐positive individuals from a seroprevalent cohort in Durban, South Africa. Two thresholds are examined, and 95% bootstrap confidence intervals are presented for the estimated time to threshold. Sensitivity analysis revealed that results are robust to truncation of the series and variation in the number of visits considered for most patients. Caution should be exercised when interpreting the estimated times for patients who exhibit very slow rates of decline and patients who have less than three measurements. We also discuss the relevance of the methodology to the study of other diseases and present such applications. We demonstrate that the method proposed is computationally efficient and offers more flexibility than existing frameworks. Copyright © 2016 John Wiley & Sons, Ltd.  相似文献

Many studies have documented associations between sexual functioning, depression, experiences of childhood sexual abuse, relationship support, and chronic pelvic pain, but none have addressed the interrelationships among all of these variables in a unified model. The aim of this preliminary study was to construct an integrative model predicting sexual functioning for women with chronic pelvic pain. Sixty-three women with chronic pelvic pain completed measures of sexual functioning for use as the criterion variable, and measures of the impact of chronic pain, depression, experiences of sexual abuse, and relationship support as predictors. The primary finding was that depression mediated the effects of child sexual abuse and partially mediated the effects of relationship support on sexual behavior and satisfaction with the sexual relationship. In addition to its indirect relationship through depression, relationship support also independently predicted sexual function. Thus, in this nonclinical sample, the effects of child sexual abuse on sexual function depended on the extent of depressive symptoms, while the influence of relationship support depended in part on depression.  相似文献
