Oxotechnetium(V) Complexes with a Novel Class of Tridentate Thiosemicarbazide Ligands

A novel tridentate thiosemicarbazide-type ligand class with an SNS donor set, H(2)L(1), was prepared by reactions of N-[N`,N`-dialkylamino(thiocarbonyl)]benzimidoyl chlorides with thiosemicarbazides. H(2)L(1) ligands readily react with (NBu(4))[TcOCl(4)] in MeOH under the formation of red oxotechnetium(V) complexes of composition [TcOCl(L(1))]. The monomeric, five-coordinate compounds are air-stable and bind (L(1))(2-) tridentate in the equatorial coordination sphere. The compounds represent the first examples of oxotechnetium(V) complexes with NS chelate-bonded thiosemicarbazones.

Using Clickers to Teach Biology-Based Material in a Developmental Psychology Class

This talk will describe a study designed to assess if clicker technology during a lesson can improve learning relative to traditional lecture alone. A control group was exposed to the stages of prenatal development via traditional lecture, and an experimental group was exposed to the material via an exercise that used clickers. A pretest showed no difference before the intervention. A posttest showed that the clicker group had significant gains indicating clickers may facilitate learning of science-based material.

Class Struggle, Elitism and Social Collectivism in Ngugi wa Thiong’o’s Devil on the Cross : A Marxist Approach

Ngugi wa Thiong’o’s Devil on the Cross represents both an insightful interpretation and a scathing critique of Kenyan politics and society during the period of neo-colonialism. The present thesis aims to explore, with the help of Marxist ideology and criticism, the relevance of the issues of class struggle, elitism and social collectivism in the novel. At the same time, this study will attempt to define Devil on the Cross as a "national allegory" depicting situations that are common to almost all post-colonial societies, and in particular, how the novel's ideological and political commitment is an important feature as it reflects Ngugi’s effort to draw attention to how Kenya and Africa as a whole suffered from imperialism, neo-colonialism, and a corrupt and greedy capitalist society.

I andras hem : Om minnesarbete som förnyelse av familjesociologi

In the home of others: exploring new sites and methods when investigating the doings of gender, class and ethnicity What role does the experience of being in and observing other people’s home play informing one’s gender and class identities and family aspirations? And how can it be explored? Through the traditions of socialization theory the everyday/-night experiences of family life are objectified into an institution (the family) with abstracted relations (mother-father-child) and functions (”primary socialization”). This is a view directly related to ruling relations through which the family is institutionalized, by rules and regulations, and made accountable as such. Hereby the question of experiences of other sites (and localities!) and other relations when forming one’s gender and family aspirations are not raised. In this article it is argued that when using an alternative approach (the method of inquiry proposed by Dorothy E. Smith) and alternative methods (memory work) the door to other homes is opened. Using experience stories a picture is drawn where new sites and relations are made visible as crucial contexts where gender and family life is explored and learned. By illuminating the ”work knowledge” of family life another way of mapping is presented, a way that extends and transforms the traditions within family research.
