Sampling seeds

Problems of sampling carbonized plant material are discussed. Firstly, the problem of actually selecting a sample in the laboratory is considered, and some experiments which investigate various procedures are described. Secondly, the statistical aspects of determining optimal sample sizes are considered. Formulae are given for calculating optimal sample sizes and confidence intervals. Upper bounds, which are independent of the total population size, are provided for the sample size required to achieve any desired accuracy.     

Where in the world are youth geographies going? Reflections on the journey and directions for the future

ABSTRACT

This viewpoints paper reflects upon the journey youth geographies have travelled over the last 20 years and highlights some thoughts on where directions for new research might be best placed in the coming decades. In particular, the paper draws attention to the growing numbers of youth in the Global South and especially in the African continent where youth populations are set to continue to rise. The paper identifies some of the potential challenges faced by the majority of youth in coming years in particular the need to decolonise thinking around youth geographies while also considering the importance of economic, social and political contexts in shaping debates. The paper charts some potential new directions while also suggesting that youth’s own perspectives need to receive greater prominence in theory and outcomes.
