To this end the difference and the odds ratio curves of the entire survivor functions over a certain time period are considered. Two asymptotic approaches for solving these testing problems are investigated, which are based on bootstrap approximations. The performance of the test procedures is investigated in a simulation study, and some guidance on which test to use in specific situations is derived. The proposed methods are applied to a trial in which two thrombolytic agents for the treatment on acute myocardial infarction were compared, and to a study on irradiation therapies for advanced non-small-cell lung cancer. Non-inferiority over a large time period of the study can be shown in both cases.

Recent accelerations in the rate of reduction in under-five mortality have been cited as a cause for optimism. In this paper, we show that changes in mortality rates are subject to mean reversion. Hence, high rates observed recently for Sub-Saharan Africa make for an overly optimistic estimate of future reductions. Taking this into account in projecting mortality rates until 2030, we find that only very few countries in Sub-Saharan Africa are likely to attain the new targets while a majority of countries elsewhere are likely to attain the target or have done so already. We also show that while MDG4 has been rightly criticized as 'unfair' to Sub-Saharan Africa in the past, a relative target may have been more appropriate today and would be relevant for all countries. We also offer a discussion of likely challenges the region faces in making further inroads against preventable deaths. (C) 2016 Elsevier Ltd.

Sources of data: Relevant studies investigating the effect of economic growth on health outcomes were identified from Google Scholar and PubMed searches in economics and medical journals. Areas of agreement: Additional resources generated through economic growth are potentially useful for improving population health. Areas of controversy: The empirical evidence on the aggregate effect of economic growth on population health is rather mixed and inconclusive. Growing points: The causal pathways from economic growth to population health are crucial and failure or success in completing the pathways explains differences in empirical findings. Areas timely for developing research: Future research should investigate how additional resources can more effectively reach those in need and how additional resources can be used more efficiently. It is particularly relevant to understand why preventive health care in developing countries is very price elastic whereas curative health care is very health inelastic and how this understanding can inform public health policy."],["dc.identifier.doi","10.1093/bmb/ldw052"],["dc.identifier.isi","000397228800005"],["dc.identifier.pmid","28069615"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/43489"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","PUB_WoS_Import"],["dc.publisher","Oxford Univ Press"],["dc.relation.issn","1471-8391"],["dc.relation.issn","0007-1420"],["dc.title","The effect of economic development on population health: a review of the empirical evidence"],["dc.type","review"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

This is a fundamental question of social behaviour, encompassing phenomena such as bird flocking, fish schooling, and the innumerable activities in human groups that require people to synchronise their actions. We have developed an experimental paradigm, the HoneyComb computer-based multi-client game, to empirically investigate human movement coordination and leadership. Using economic games as a model, we set monetary incentives to motivate players on a virtual playfield to reach goals via players' movements. We asked whether (I) humans coordinate their movements when information is limited to an individual group member's observation of adjacent group member motion, (II) whether an informed group minority can lead an uninformed group majority to the minority's goal, and if so, (III) how this minority exerts its influence. We showed that in a human group--on the basis of movement alone--a minority can successfully lead a majority. Minorities lead successfully when (a) their members choose similar initial steps towards their goal field and (b) they are among the first in the whole group to make a move. Using our approach, we empirically demonstrate that the rules of swarming behaviour apply to humans. Even complex human behaviour, such as leadership and directed group movement, follow simple rules that are based on visual perception of local movement."],["dc.description.sponsorship","Open-Access-Publikationsfonds 2014"],["dc.identifier.doi","10.1371/journal.pcbi.1003541"],["dc.identifier.pmid","24699264"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/10063"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/15398"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","final"],["dc.relation.eissn","1553-7358"],["dc.relation.orgunit","Wirtschaftswissenschaftliche Fakultät"],["dc.rights","CC BY 4.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/4.0/"],["dc.title","Leadership in Moving Human Groups"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
