Separation of stomach contents using the sieve-tower technique]

The authors present a method to separate and preserve stomach contents for forensic purpose. Analysis by "sieve tower" technique is simple and quickly done during autopsy. Solid phases of stomach content are arranged size up and can be stored for subsequent examinations. With the fluid phase drug analysis or microscopic analysis to confirm identy of the foodstuffs may be done. By adding alcohol (70%) enzymatic digestion and bacterial degradation of the stomach content are stopped.     

Contextual orientation in policy analysis: The contribution of Harold D. Lasswell

Criticized for its generally positivist and technocratic orientation, the literature of public policy analysis has begun to generate proposals that would create a convergence between the field and the wider movement for a post-positivist restructuring of social inquiry. Ironically, critics have often focused on policy science as the epitomy of positivism and technocracy, giving little attention to the actual position of the figure responsible for the term - Harold D. Lasswell. Centering on Lasswell's key concept of contextual orientation, this article argues that, despite positivist influences, he developed an approach to inquiry and a proposal for a policy science profession which together clearly transcend positivism and technocracy- which, indeed, anticipate recent post-positivist proposals. Implications for policy analysis of a project of contextual orientation are also considered, along with problems in Lasswell's focus on professionalization.
