Beyond evidence versus truthiness: toward a symmetrical approach to knowledge and ignorance in policy studies

Representation of cerebral bridging veins in infants by postmortem computed tomography

The postmortem diagnosis of shaken baby syndrome, a severe form of child abuse, may be difficult, especially when no other visible signs of significant trauma are obvious. An important finding in shaken baby syndrome is subdural haemorrhage, typically originating from ruptured cerebral bridging veins. Since these are difficult to detect at autopsy, we have developed a special postmortem computed tomographic (PMCT) method to demonstrate the intracranial vein system in infants. This method is minimally invasive and can be carried out conveniently and quickly on clinical computed tomography (CT) systems. Firstly, a precontrast CT is made of the infant's head, to document the original state. Secondly, contrast fluid is injected manually via fontanel puncture into the superior sagittal sinus, followed by a repeat CT scan. This allows the depiction of even very small vessels of the deep and superficial cerebral veins, especially the bridging veins, without damaging them. Ruptures appear as extravasation of contrast medium, which helps to locate them at autopsy and examine them histologically, whenever necessary.     

Can process conditionality enhance aid effectiveness?

Can process conditionality enhance poverty reduction in developing countries? We address this question in a political-economic framework with political distortions on the recipient and the donor side. Process conditionality is a useful tool only if the international financial institutions hold all necessary information to assess the political situation in recipient countries and to select the true representatives of the poor into a participatory process. If they do not hold this information or if bureaucratic interests reduce their incentive to acquire this information, process conditionality loses its effectiveness.     

The Political Economy of the Enhanced HIPC-Initiative

Only three years after its endorsement bythe World Bank and the IMF, the HeavilyIndebted Poor Country (HIPC) – Initiativewas considerably altered and enhanced. Thispolicy shift can be explained as a resultof utility maximization behavior bynational and international politicians,international bureaucrats and NGO. Apolitico-economic model suggests that theoverall rise of HIPC default risk and thesymbolic value of the year 2000 have beenthe two major determinants of changes involume, eligibility, and conditionalityrequirements.     

The Association Between Parental Rearing Dimensions and Adolescent Psychopathology: A Cross-Cultural Study

Research on parental rearing dimensions faced ethnocentric criticism for mainly focusing on adolescents in Western industrialized countries. Over the past decade, the phenomenon of anxious parenting, so called “helicopter parenting”, gained attention in popular media as well as scholarly publications in addition to support and psychological control. Whether these parenting dimensions, which were associated with different health outcomes in adolescents, were only occurring in the Western world or are visible cross-culturally, has not been sufficiently studied. Therefore, it is unclear whether these links exist also for adolescents from other parts of the world. Additionally, the involvement of fathers in child rearing continues to be neglected in adolescent psychopathology research. The current cross-cultural study tested the association of maternal and paternal rearing dimensions with youth internalizing and externalizing psychopathology in a sample of 2415 adolescents (56% female, 15.33 years, SD?=?0.61) from eight countries (Argentina, France, Germany, Greece, Pakistan, Peru, Poland, and Turkey). Hierarchical regression models showed that internalizing symptomatology was associated with mothers’ support, psychological control, and anxious rearing as well as fathers’ psychological control up and above predictors like country and mother’s level of education. For predicting externalizing symptomatology, mother’s anxious rearing, mother’s psychological control, and father’s support as well as father’s psychological control were significant up and above adolescents’ gender, standard of living, and country. To conclude, across countries, anxious rearing and psychological control experienced from both parents were substantially linked with adolescent mental health.
