As a consequence, ecocriticism concentrates on ecopoetical, animal studies on zoopoetical elements and modes of representation in literature (and the arts more generally).

This report groups those structural elements which are often found to form the basis for a metabolism to such chemically reactive metabolites. ~mpounds which are chemically reactive per se and which do not require metabolic activation form group 1. Group 2 compri~es of olefins and aromatic hydrocarbons where the oxidation via an epoxide can be responsible for the generation of reactive species. Aromatic amines, hydrazines, and nitrosamirres form group 3 requiring an oxidation of a nitrogen atom or of a carbon atom in alpha position to a nitrosated amine. Group 4 compounds are halogenated hydrocarbons which can either give rise to radicals or can form an ·olefin (group 2) upon dehydrohalogenation. Group 5 compounds depend upon some preceding enzymatic activity either not available in the target cell or acting on positions in the molecule which are not directly involved in the subsequent formation of electrophilic atoms. Examples for each group are taken from the "List of Chemieals and Irrdustrial Processes Associated with Cancer in Humans" as compiled by the International Agency for the Research on Cancer, and it is shown that 91\% of the organic carcinogens would have been detected on the basis of structural elements characteristic for group 1-5. As opposed to this very high sensitivity, the specificity ( the true negative fraction) of using this approach as a short-term test for carcinogenicity is shown to be bad because detoxification pathways have so far not been taken into account. These competing processes are so complex, however, that either only very extensive knowledge about pharmacokinetics, stability, and reactivity will be required or that in vivo systems have to be used to predict, on a quantitative basis, the darnage expected on the DNA. DNA-binding experiments in vivo are presented with benzene and toluene to demonstrate one possible way for an experimental assessment and it is shown that the detoxification reaction at the methyl group available only in toluene gives rise to a reduction by at least a factor of forty for the binding to rat liver DNA. This quantitative approach available with DNA-binding tests in vivo, also allows evaluation as to whether reactive metabolites and their DNA binding are always the most important single activities contributing to the overall carcinogenicity of a chemical. With the example of the livertumor inducing hexachlorocyclohexane isomers it is shown that situations will be found where reactive metabolites are formed and DNA binding in vivo is measurable but where this activity cannot be the decisive mode of carcinogenic action. It is concluded that the lack of structural elements known to become potentially reactive does not guarantee the lack of a carcinogenic potential.}, subject = {Toxikologie}, language = {en} } @inproceedings{HommersEndres1988, author = {Hommers, Wilfried and Endres, Johann}, title = {Strafe und Schadensersatz als multivariater Response Komplex}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-43895}, year = {1988}, abstract = {No abstract available}, language = {de} } @inproceedings{Ellgring1983, author = {Ellgring, Johann Heinrich}, title = {Spezifische Signalsysteme in der menschlichen Interaktion}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-50212}, year = {1983}, abstract = {Nonverbal communicative behaviours are associated with affective states in a way specific to the individual. This result emerged from longitudinal studies on depressed patients. From the analysis of various nonverbal behaviours it can be concluded that the depressed state is indicated by nonverbal elements in a logical "or-" rather than "and-connection" or in a hierarchical way. It is maintained that the relationship of psychological relevant states (mood) and nonverbal behaviour needs to be studied by intra-individual comparisons to reveal the specifically close relationships effective in everyday communication. With regard to the pragmatic aspect of communication, elements in the nonverbal signalling system seem to possess different levels of generality. However, from decoding studies it can be shown that even very subtle behavioural differences can be detected by an observer. Thus specific signals can become effective in interaction given a familiarity with the idiosyncratic usage.}, subject = {Psychologie}, language = {de} } @inproceedings{KohnenKrueger1981, author = {Kohnen, Ralph and Kr{\"u}ger, Hans-Peter}, title = {Soziale Situationen als experimentelle Bedingungen der Pharmakopsychologie}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-86041}, year = {1981}, abstract = {Summary (Social Situations as Experimental Conditions in Psychopharmacology): To reduce a great variability of drug effects in healthy subjects, stress conditions are used often in pharmacopsychology. However, empirical results show that the desired stress effects are failing. This paper suggests to realize social stress Situations as interactions between subjects, expecting higher challenging effects than experimentator-subject-interactions, usually used in experimental designs. Two experimental studies are reported: the call-upsituation and the group-therapy situation. The experimental effects were measured by changes of pulse-frequencies. The results indicate that in the two situations high and low dosages of tranquilizing drugs lead to comparable (and so predictable) effects only, if a Situation is high challenging for the experimental subjects. The call-up situation, which proves performance, challenges male subjects highly. The emotional or social competence demanding group-therapy situation is a high challenging situation for warnen. It is concluded that no situation is stressing a person generally. Depending from personality characteristics, differential stressor effects appear.
