Members of Braconidae (Hymenoptera: Ichneumonoidea) are mostly parasitoids of other holometabolous insects. It is a large family with a little over 18,000 described species and many more to be described. Subfamily classification in this group has been unstable and resolution of phylogenetic history at the subfamily level has been problematic. Since 1993, no new keys to the subfamilies of Braconidae have been produced. Many taxonomic and phylogenetic changes have taken place since then, including a recent phylogeny proposing 47 subfamilies and representing the most robust and resolved analysis to date. A pressing need for new keys to the world subfamilies of Braconidae is evident. Using the free programs, DELTA and INTKEY, easy to use keys to the subfamilies of Braconidae, both dichotomous and interactive were produced that will be published and freely available on the Internet. These are constructed for use by professionals and amateurs alike.

I tidigare forskning visas ett samband mellan framställningen av kvinnor i media och kvinnors självbildsuppfattning. Studier har även gjorts med fokus på män där ett samband mellan media och mäns självbild visas. Studien avser undersöka om det finns ett samband mellan medias framställning av ideala modeller och unga vuxnas syn på kroppslig självbild, samt hur mediaanvändning skiljer sig mellan könen och om användningen har en effekt på kroppslig självbild. En enkätundersökning med 90 deltagare (43 kvinnor och 47 män) i ålder 18-30 utfördes. Deltagarna fick fylla i en internetenkät med antingen ideala bilder, alldagliga bilder eller en enkät utan bilder. Mätinstrumentet som används är The Body Self Esteem Scale. Inget signifikant resultat gavs kring effekten av bildexponering, däremot hittades signifikanta skillnader mellan könen på olika BES-Items, däribland lår, vikt och midja. Det förväntade mönstret återspeglade sig i resultatet, om än inte signifikant. I resultatdiskussionen diskuteras studiens svagheter såsom den korta exponeringen av bilderna.

none / This thesis explores whether hosting the Beijing Olympic Games has helped promote China’s images as measured by quantitative and qualitative analysis of news coverage on China in Time and The Economist. Content analysis showed that coverage on China in both magazines increased as the Beijing Olympic Games neared. Both Time and The Economist paid the most attention to China’s “politics,” “economics,” and “society,” while “education” and “health” received the least coverage. The newsmagazines covered China more negatively than positively; however, Time demonstrated a friendlier stance towards China than The Economist. In terms of length of article, both magazines spent the most number of pages covering “general,” or articles that cover more than one subject, followed by “health” and “economics” in Time and “environment” and “economics” in The Economist. Discourse analysis showed the frames used to cover China in the newsmagazines were, China as a country that suppresses its people’s rights, China as a country full of chances yet beware of risks and uncertainties, China as a country working on environmental protection, China as a country short of resources, the Internet as a medium changing Chinese youth’s way of living, China as an unstable and unequal developing country, China as a country with flowering creativity amid low acceptance, China’s problematic education system yet willing to make changes, China lags in healthcare, disease surveillance and control. Manheim and Albritton (1994) argue that a nation’s image is boosted when positive coverage increases, while negative coverage decreases. This study found that hosting the Olympic Games helped promote China’s images in Time more significantly than in The Economist, particularly in “economics,” “environment,” “technology,” and “culture and leisure”.

This thesis explores the problem of how to present digital images of ancient artifacts in a manner that supports the task of visual analysis. The real object presents the "truth": exact scale, colour, and fine details. An original work of art provides the viewer with the opportunity to react directly with the object, is closest to the impact intended by the artist, and provides a tangible physical link with the past. Digital images limit and alter the experience of a work of art (1) with regard to the amount of data available (resolution), and (2) through the interpretation of the object by the producers of the digital copy (mediation). A new framework is developed to improve the understanding and presentation of virtual artifacts. This Fidelity-Mediation framework provides a continuum for considering the effects of design strategies on media used in teaching Classical arch�ology. Two small-scale experiments and follow-up interviews were undertaken to assess the usefulness of the Fidelity-Mediation framework as a descriptive model. During the experiments, quantitative analysis could detect no statistical difference in the effectiveness of different types of presentation (real object, VR object, and still digital images). This is a surprising result as it might be expected that there is nothing like seeing the real thing. Digital images provide less visual integrity. However, the digitised artifacts make up for the loss of excitement and authenticity by providing the advantage of mediated focus. Digitised artifacts thus turn out to be useful, effective study tools in the analysis of Classical art. Findings from this research are expected to generalise only to learning situations which support task orientation--situations conducive to developing personal skills and mastery--in contrast to performance orientation where the goal is to display performance relative to others. The distinction between task orientation and performance orientation is discussed in Chapter Eight of this thesis.
