This article considers how the children's books written by two nineteenth-century female writers, Eliza Tabor and Mary Martha Sherwood, when they accompanied their husbands to India, enabled them to navigate this new environment and their position as respectable middle-class women while revealing how India was deemed a place where British childhood was impossible. Just as many women took up botanical study to legitimise their ‘otherwise transgressive presence in imperial spaces’ (McEwan 219), writing for children enabled others to engage with the masculine world of travelling and earning money without compromising their femininity. Addressing their work to children also seems to have helped both writers to deal with the absence of their own children: the Indian climate made it impossibly challenging for most British infants and children. In this way their writing gives expression to what might be termed a crisis of imperial motherhood. Underlying the texts is an anxiety relating to British settlement and an attempt to comprehend and control a place that threatened their maternal roles.

Information of legitimacy of oil palm progenies is important to guaranty the quality and to control commercial seeds procedures. A true and legitimate cross will produce progeny which has a combination of their parent's allele. The information could be obtained early in the nursery stage through DNA fingerprinting analysis. Simple Sequence Repeats (SSR) is one of DNA markers used for DNA fingerprinting, since the marker system has advantages to acquire information of allele per individual in population and efficiency diverse allele of progeny and their parents. The aim of the research is to obtain legitimacy of 12 progenies analyzing in the oil palm nursery stage. Thirteen SSR markers were used to analyze 12 crossings number of oil palm. The genotypes data by alleles of SSR inferred and quantified using Gene Marker® Software version 2.4.0 Soft Genetics® LLC and analyzed based on Mendel's Law of Segregation. The result showed based on heredity pattern of progeny and their parent's allele that progenies H were indicated genetically derived from their known parents while progenies from A and G indicated as illegitimate crossing. Probability value for legitimacy of progenies of 9 other crosses has 0.031 and 0.5. Legitimacy analysis of progeny using SSR markers could be used to control the quality of crossing material and earlier selection in the oil palm nursery.

African pollination weevil (Elaeidobius kamerunicus Faust) has an important role in the productivity of Indonesian oil palm plantation. Up to now, there has not been a comprehensive biological study of the species at molecular level. The basic knowledge is very useful for exploitation of the weevil for effective oil palm fruit set development. This research aimed to obtain DNA extraction protocol of E. kamerunicus for DNA fingerprinting of the species. Results showed that using a DNA extraction kit,material disruption by using micro pestle resulted the highest quantity of DNA, while there were no significant differences of resulted DNA quantity among treatments using tissue lyser for material disruption. DNA extracted by using micro pestle or tissue lyser for material disruption is adequate for DNA fingerprinting using AFLP (Amplified Fragment Length Polymorphism) and sequencing techniques.
