Decentralisation and government provision of public goods: The public health sector in Uganda

While many developing countries have devolved health care responsibilities to local governments in recent years, no study has examined whether decentralisation actually leads to greater health sector allocative efficiency. This paper approaches this question by modeling local government budgeting decisions under decentralisation. The model leads to conclusions not all favourable to decentralisation and produces several testable hypotheses concerning local government spending choices. For a brief empirical test of the model we look at data from Uganda. The data are of a type seldom available to researchers–actual local government budgets for the health sector in a developing country. The health budgets are disaggregated into specific types of activities based on a subjective characterisation of each activity's ‘publicness’. The empirical results provide preliminary evidence that local government health planners are allocating declining proportions of their budgets to public goods activities.     

An assessment of early mandibular growth

Quantification of skeletal data has been shown to be an effective and reliable method of demonstrating variation in human growth as well as for monitoring and interpreting growth. In South Africa as well as internationally, few researchers have assessed mandibular growth in late fetal period and early childhood and therefore standards for growth and age determination in these groups are limited. The purpose of this study was to evaluate growth in the mandible from the period of 31 gestational weeks to 36 months postnatal. A total of 74 mandibles were used. Dried mandibles were sourced from the Raymond A. Dart Collection (University of Witwatersrand), and cadaveric remains were obtained from the Universities of Pretoria and the Witwatersrand. The sample was divided into four groups; 31-40 gestational weeks (group 1), 0-11 months (group 2), 12-24 months (group 3), and 25-36 months (group 4). Twenty-one osteological landmarks were digitized using a MicroScribe G2. Ten standard measurements were created and included: the maximum length of mandible, mandibular body length and width, mandibular notch width and depth, mental foramen to inferior border of mandible, mandibular basilar widths bigonial and biantegonial, bigonial width of mental foramen and mental angle. Data were analyzed using PAST statistical software and Morphologika2 v2.5. Statistically significant differences were noted in the linear measurements for all group comparisons except between groups 3 and 4. The mandible morphologically changed from a round, smooth contour anteriorly to adopt a more sharp and narrow adult shape. A progressive increase in the depth and definition of the mandibular arch was also noted. In conclusion, the mandible initially grows to accommodate the developing tongue (up to 11 months), progressive dental eruption and mastication from 12 to 36 months. Mastication is associated with muscle mass development; this would necessitate an increase in the dimensions of the mandibular notch and associated muscle attachment sites. These findings might be valuable in the estimation of age in unidentified individuals and to monitor prenatal growth of the mandible for the early diagnosis of conditions associated with stunted mandibular growth.     

Are Outcome Fairness and Outcome Favorability Distinguishable Psychological Constructs? A Meta-Analytic Review

Manipulations of outcome favorability and outcome fairness are frequently treated as interchangeable, and assumed to have redundant effects. Perceptions of outcome fairness and outcome favorability are similarly presumed to have common antecedents and consequences. This research tested the empirical foundation of these assumptions by conducting a meta-analytic review of the justice literature (N = 89 studies). This review revealed that outcome fairness is empirically distinguishable from outcome favorability. Specifically: (a) there is weaker evidence of the fair process effect when the criterion is outcome fairness than when it is outcome favorability, (b) outcome fairness has stronger effects than outcome favorability, and equally strong or stronger effects as procedural fairness on a host of variables, such as job turnover and organizational commitment, and (c) manipulations of outcome fairness and favorability have stronger effects on perceptions of procedural fairness than the converse.     

Stature- and age-related bias in self-reported stature.

The use of reported stature, especially self-reported stature such as on a driver's license, as a proxy for measured stature is necessary when measured stature is unavailable, for example, in matching data calculated from skeletal remains with data for missing persons. The accuracy of self-reported stature for older persons and especially for tall and short people is not well ascertained. Examination of published reports provides evidence that beginning at age 45, people compound their stature overestimation by an additional amount related to age (women by twice the amount of men). Analysis of anthropometric data from 8000 U.S. Army personnel indicates that the amount of general overestimation of stature by men is 2 1/2 times greater than that by women. Neither tall men nor tall women underestimate their stature, but men in the upper third of the stature range, and women in the upper 10%, self-report their stature with greater accuracy. No trends in accuracy are apparent in the remainder of the stature spectrum for men or women.
