T1  - Qualifizierende und varianzreduzierende Wirkungen von Schulklassenunterricht
N2  - Schulklassenunterricht soll möglichst vielen Schülern ein möglichst hohes kognitives Leistungsniveau erreichen helfen. Nur wenige Unterrichtsstudien haben bisher jedoch zur Aufklärung jener Lehr-Lern-Bedingungen beigerragen, unter denen sich hohe qualifikatorische und varianzreduktive Wirkungen gleichzeitig erreichen lassen. Die vorliegende Studie greift dafür auf Merkmale einer adaptiv-remedialen Lehr-Lern-Organisation zurück und überprüft ihren Erklärungsgehalt im Mathematikunterricht von 58 fünften Hauptschulklassen. Zur systematischen Entwicklung komplexer Erklärungen und ihrer einzelfallartigen Beurteilung wird ein neu entwickeltes Programmsystem (HYPAG) angewandt. Es fühn zur Auswahl einer Annahmenstruktur, in der Instrumental- und Rahmenbedingungen von Schulklassenunterricht in Wechselwirkung stehen, für sich genommen aber nur mehr hinreichende und darin substiruierbare Bedingungen qualifizierender und varianzreduktiver Unterrichtseffekte sind.

T1  - Kausalmodelle in der Pädagogischen Psychologie - Ergänzende Analysen zu zwei einschlägigen Untersuchungen
N2  - In the present secondary analysis the results of studies by Simons et al. (1975) and Schwarzer (1979) were critically reanalyzed. The central point of the reanalysis concerned the test of the causal models used, especially the question, if the technique of path analysis was correctly applied. Whereas some modifications seemed necessary in both srudies, there was no reason to question their main results.

T1  - Effect of selected induction of microsomal and nuclear aryl hydrocarbon monooxygenase and epoxide hydrolase as well as cytoplasmic glutathione S-epoxide transferase on the covalent binding of the carcinogen benzo(a)pyrene to rat liver DNA in vivo
N2  - Groups of four adult male rats [ZUR:SIV -Z] were pretreated with corn oil (control; 2 ml/kg/day i. p. for 3 days), trans-stilbene-oxide (SO; 200 mg/kg/day i. p. for 2 days), 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD; 10 \(\mu\)g/kg i. p. once, 4 days before killing), phenobarbital (PB; 1 gjliter in the drinking water for 8 days), and dieldrin (20 mg/kg/day i. p. for 3 or 9 days). They received an injection of [G-\(^3\)H]benzo(a)pyrene (BaP, 31 \(\mu\)g/kg, 7.4. 10\(^9\) dpm/kg; i. v.) 16 h before killing. In the liver of each rat, five enzymatic activities and the covalent binding of BaP to DNA have been determined. The rnicrosomal aryl hydrocarbon monooxygenase activity (AHM) ranged frorn 75% of control (SO) to 356% (TCDD), the nuclear AHM from 63% (SO) to 333% (TCDD). Microsomal epoxide hydrolase activity (EH) was induced up to 238% (PB), nuclear EH ranged from 86% (TCDD) to 218% (PB). A different extent of induction was observed in the two compartments. Highest induction of glutathione S-epoxide transferase activity (GST) was found with PB (202%). The DNA binding of BaP was modulated within 79% (dieldrin, 9 days) and 238% of control (TCDD). An enzyme digest of control DNA was analysed by Sephadex LH-20 chromatography. Multiple linear regression analysis with all data expressedas o/o of control yielded the following equation: DNA Binding = 1.49 · Microsomal AHM- 1.07 · Nuclear AHM+ 0.33 · Microsomal EH- 0.52 · N uclear EH+ 0.11 · Cytoplasmic GST + 58.2. From this analysis it is concluded that (1) AHM located in the endoplasmic reticulum is most important in the formation of DNA-binding metabolites, (2) EH in the same compar.tment is not determinative in thls respect nor has it a protective effect, (3) both membrane-bound enzyme activities located in the nucleus may inactivate potential ultimate carcinogens, and ( 4) cytoplasmic GST probably cannot reduce DNA binding due to its subcellular localization.

T1  - In vivo covalent binding of aflatoxin metabolites isolated from animal tissue to rat-liver DNA
N2  - Ring-labelled [\(^{14}\)C)aflatoxin B\(_1\) (AFB\(_1\)), prepared by biosynthesis. or generally labelled [\(^3\)H]AFB\(_1\) was administered by oral gavage to young adult male rats. After 6 hr. the liver was removed and two fractions were isolated, namely macromolecules, which contamed about 3 % of the initial dose of AFB\(_1\) radioactivity. and water-soluble, low-molecular aftatoxin conjugates containing about0·2% of the administered radioactivity. These two fractions were administered orally to other rats in order to determine the potential of radioactive aftatoxin residues for covalent binding to DNA. Such binding can be used as an indicator for carcinogenic potency. Liver DNA was isolated 9-12 hr after admmistration of the aflatoxin derivatives and in no case was any radioactivity detected on the DNA. It can be deduced on the basis of the limit of detection of radioactivity on the DNA, that macromolecule bound AFB\(_1\) derivatives are at least 4000 times less active than AFB\(_1\) with respect to covalent binding to rat-liver DNA. and that the water-soluble conjugates are at least 100 times less potent than AFB, itself. It is concluded that the carcinogenic risk for humans who consume liver or meat. containing such aflatoxin residues is negligible when compared with the risk from intake of aftatoxins in other food items.

T1  - In vivo covalent binding of aflatoxin B\(_1\) and aflatoxin M\(_1\) to liver DNA of rat, mouse and pig
N2  - [\(^{14}\)C] Aflatoxin B\(_1\) (AFB\(_1\)) was isolated from cultures of Aspergillus parasiticus grown on [1-\(^{114}\)C] sodium acetate. Covalent binding of AFB1 to liver DNA of rat and mouse was determined 6-8 h afteroral administration. The effectiveness of covalent binding, expressedas DNA binding per dose in the units of a 'Covalent Binding Index' (CBI), (\(\mu\)mol aflatoxin/mol DNA nucleotides)/(mmol aflatoxin/kg animal), was found to be 10 400 for rats and 240 for mice. These CBI partly explain the different susceptibility of the two species for the incidence of hepatic tumors. The corresponding values for pig liver DN A, 24 and 48 h after oral administration, were found to be as high as 19 100 and 13 300. DNA-binding has not so far been reported for this species although it could represent an appropriate animal model for studies where a human-like gastrointestinal tract physiology is desirable. Aflatoxin M \(_1\) ( AFM\(_1\)) is a metabolite found in the milk of cows that have been fed AFB\(_1\)-contaminated diet. [\(^{14}\)C] AFM\(_1\) was also found to be produced by cultures of A. parasiticus giving a yield of about 0.3% of the total aflatoxins. A test for covalent binding to rat liver DN A revealed a CBI of 2100 shoWing that AFM\(_1\) must also be regarded as a strong hepatocarcinogen. It is concluded that AFB\(_1\) contaminations should be avoided in dairy feed.

T1  - N,N'-dicyclohexylcarbodiimide binds specifically to a single glutamyl residue of the proteolipid subunit of the mitochondrial adenosinetriphosphatases from Neurospora crassa and Saccharomyces cerevisiae
N2  - T~e N,N'-dicrclohexylcarbodiimide-binding proteolipid subumt of the mitochondrial adenosinetriphosphatases (ATP phosphohydrolase, EC 3.6.1.3) of Neurosporacrassa and Saccharomyces cerevisiae were purified from mitochondria incubated with the radioactively labeled inhibitor. The specifically labeled subunit was cleaved with cyanogen bromide and N-bromosuccinimide, and the resultant fragments were separated by gel chromatography in the presence of 80% (vol/vol) formic acid. The N,N'-dicyclohexylcarbodiimide label was recovered in each organism exclusively in a 17-residue fragment. Further analysis by automated solid-phase Edman degrada.ti.on revealed tha~ the bound label was present at only one positIOn, correspondmg to a glutamyl residue.

T1  - Identification of amino-acid substitutions in the proteolipid subunit of the ATP synthase from dicyclohexylcarbodiimide-resistant mutants of Escherichia coli
N2  - The amino acid sequence of the proteolipid subunit of the A TP synthase was analyzed in six mutant strains from Escherichia coli K 12, selected for their increased resistance towards the inhibitor N,N'-dicyclohexylcarbodiimide. All six inhibitor-resistant mutants were found to be altered at the same position of the proteolipid, namely at the isoleucine at residue 28. Two substitutions could be identified. In type I this residue was substituted by a valine resulting in a moderate decrease in sensitivity to dicyclohexylcarbodiimide. Type II contained a threonine residue at this position. Here a strong resistance was observed. These two amino acid substitutions did not influence functional properties of the ATPase complex. ATPase as well as A TP-dependent proton-translocating activities of mutant membranes were indistinguishable from the wild type. At elevated concentrations, dicyclohexylcarbodiimide still bound specifically to the aspartic acid at residue 61 of the mutant proteolipid as in the wild type, and thereby inhibited the activity of the ATPase complex. It is suggested that the residue 28 substituted in the resistant mutants interacts with dicyclohexylcarbodiimide during the reactions leading to the covalent attachment of the inhibitor to the aspartic acid at residue 61. This could indicate that these two residues are in close vicinity and would thus provide a first hint on the functional conformation of the proteolipid. Its polypeptide chain would have to fold back to bring together these two residues separated by a segment of 32 residues.

Accordingly, the following questions may be examined: are intra-individual changes in speech and gaze behaviour related to changes in the internal psychopathological state? Further, do these changes occur synchronously to changes in the state of subjective well-being? A longitudinal study was made on depressed patients. Their behaviour was observed during standardised interviews and diagnostic-therapeutic discussions held at regu~ lar intervals. Various speech and gaze parameters were examined with respect to their coordination and their relationship to the subjective state of well-being. Considerable variation was found in the temporal relationship amongst these variables. The results are discussed with respect to the relevance of speech parameters and the coordination of verbal and nonverbal behaviour as indicators of the psychopathological condition.

T1  - Situational effects on the syntax of speech and gaze behaviour in dyads
N2  - A substantial literature exists on the coordination of speaking and looking behaviour and their significance as indicators for the production and reception of social information. Within this framework, the temporal organisation of such behaviour has been 'shown to reflect both the coordination within the individual and between participants in a situation. In this paper, it is proposed that observed behavioural sequences may be formally described by rules of syntax, thus implying the likelihood of structural organisation as opposed to, for example, linear time dependence between behavioural states. This being the case, differing sets of rules and grammars respectively can be expected for various social situations. Clinical interviews and discu~sions between couples on a topic of marital conflict were analysed, the on-off patterns of speech and gaze being taken as data. The resulting behavioural repertoire was regarded, in the sense of a formal grammar, as the terminal vocabulary. A set of rewriting rules was determined and their associated probabilities inferred. The situational conditions were found to be reflectedin the syntactic features of the grammatical model - the terminal vocabulary, the production rules and the production probabilities.

T1  - Information processing in children's choices among bets
N2  - Children's information processing of risky choice alternatives was investigated in two studies without using verbal reports. In Study 1, the ability to integrate the probabilities and the payoffs of simple bets was examined using the rating scale methodology. Children's choices among three of those simple bets were recorded also. By cross-classifying the children's choice and rating behavior it was shown that a three-stage developmental hypothesis of decision making is not sufficient. A four-stage hypothesis is proposed. In Study 2, the influence of enlarging the presented number of alternatives from two to three and the influence of the similarity of the alternatives on children's choice probabilities was examined with those bets. Children's choice behavior was probabilistic and was influenced only by enlarging the presented number of alternatives. These results suggest that a Bayesian approach, based on two probabilistic choice models, should not be applied in order to analyze children's choice behavior. The functional measurement approach is, as was demonstrated in Study 1, a powerful implement to further the understanding of the development of decision making.

T1  - Eine neue Methode zur Prüfung der Wirkung von Psychopharmaka - Die "Weltbeschreibung"
N2  - Kompensation und das Problem der Zuggebbarkeit werden als die beiden wichtigsten Störquellen bei der Erfassung pharmakonbedingter Befindlichkeitsänderungen dargestellt. Gefördert werden diese Prozesse durch eine Zentrierung der Methode auf die Selbstbeobachtung. Es wird die Hypothese aufgestellt, daß die Selbstbeobachtung ersetzbar ist durch eine Beschreibung der "Welt draußen". Die Person kann sich nur in der Welt erleben - folglich werden Veränderungen dieses Erlebnis auch Veränderungen in der Beschreibung der Welt nach sich ziehen. Ausgehend von dieser Hypothese wird ein Experiment konzipiert, in dem die Vpn lediglich die experimentelle Situation und die am Experiment beteiligten anderen Vpn beschreiben, nicht aber sich selbst. Es kann gezeigt werden, daß mit den so gewonnenen Maßen eindeutige Wirkungen des eingesetzten Tranquilizers nachgewiesen werden können, ebenso eindeutige Dosis-Wirkungs-Beziehungen. Die Konsequenzen für eine pharmakopsychologische Methodik werden diskutiert. Zudem wird herausgehoben, daß Tranquilantien dann als positiv bewertet werden können, wenn sie die Reagibilität der Vpn auf die Situation erhöhen und durch eine Verringerung des allgemeinen Aktivierungsniveaus eine adäquate Verarbeitung angstinduzierender Situatonen ermöglichen.
N2  - Compensation and readiness to admit drug effects are described as the most important modifying factors in assessing changes of mood that is due to psychotropic drugs. Both processes are advanced by a methodology which focuses on the selfobservation of the experimental subjects. The authors propose the hypothesis that seifreports may be replaced by a description of the "outside world". The human being is only able to experience itself within its concrete world; consequently, changes of its experience entail changes of the description of the world. On the basis of this hypothesis an experiment is conceived in which the subjects describe only the experimental situation and the other participating subjects, not themselves, however. The authors hold that the parameters emerging from this approach give evidence both of clear-cut tranquilizer-effects and stable drug-dosage-relationships. Consequences for pharmaco-psychological methodology are discussed. The authors accentuate that tranquilizers can be seen as having positive effects if they help to enhance the subject's reagibility to the situation and, by reducing the general activation level, enable the subject to cope with anxiety inducing situations.

T1  - Wirkungen von Psychopharmaka auf das Lärmerleben
N2  - In allgemeinpsychologischen Lärmexperimenten ist eine monotone Beziehung zwischen physikalischer Lautstärke und erlebter Lautheit bestens abgesichert. In der vorliegenden Arbeit wird gezeigt, daß diese Beziehung unter Medikationsbedingungen nicht gilt. In einem 3 X 3 X 2-faktoriellen Versuchsplan mit den Faktoren physikalische Lautstärke (weißes Rauschen in 76, 79 und 82 dB), Medikation (Tranquilizer, Plazebo, Stimulizer) und (niedere bzw. hohe) Ansprechbarkeit auf Medikamente beurteilten insgesamt 54 junge weibliche Versuchspersonen in sechs Durchgängen eine Serie von 12 gleichabständigen Lärmstufen von 58 bis 92 dB in bezug auf die erlebte Lautheit. Es war weder eine Hauptwirkung Physikalische Lautstärke noch Medikation aufgetreten, dafür differenzierte die Schichtungsvariable Ansprechbarkeit auf beiden Faktoren. Eine Interpretation der Ergebnisse sensu Eysencks Drogenpostulat und im Sinne einer Aktivierungstheorie wird vorgenommen. Als Konsequenz für pharmakopsychologisches Experimentieren wird die Forderung erhoben, die in das Experiment eingebrachten Unabhängigen Variablen in ihrer Wirkung auf das Erleben der Vpn zu kontrollieren (subjektive Repräsentation des experimentellen Angebotes).
N2  - 54 young female subjects were required to report the experienced loudness of aseries of 12 white noises of 58 to 92 db, after having taken a tranquillizer, a placebo, or a stimulant, in a room with a white noise of 76, 79, or 82 db, respectively. The subjects were divided into two groups according to their sensitivity to drugs. The subjects being sensitive to drugs, expeiienced the loudness of the whole series of white noises, after having taken the tranquillizer, or in the room with a white noise of 76 or 79 db, respectively, as "high", and after having taken the stimulant, or in the room with a white noise of 82 db, as "low". On the contrary, the subjects being not sensitive to drugs, experienced the loudness of the whole series of white noises, after having taken the stimulant, or in the room with a white noise of 82 db, as "high", and after having taken the tranquillizer, or in the room with a white noise of 76 or 79 db, respectively, as "low". The results were discussed in the light of Eysenck's theory of drugeffects and of an activation theory. The results show the necessity of controlling the experienced intensity of loudness in pharmaco-psychological experiments.

T1  - Eine exakte nonparametrische Prüfung auf Kovariation zweier autokorrelierter Zeitreihen
N2  - Häufig tritt in der psychologischen und psychiatrischen Forschung die Frage nach dem Zusammenhang zwischen zwei oder mehreren Zeitreihen auf. übliche Kovariationsmaße versagen dabei vor allem deshalb, weil sie nicht inferentiell ausgewertet werden können. An einem Beispiel aus der Pharmakopsychologie wird ein auf Pfanzagl (1963) zurückgehendes Verfahren vorgeschlagen, das es erlaubt, voraussetzungsfrei den Zusammenhang zwischen autokorrelierten Meßwertreihen zu prüfen. Als Unabhängigkeit zweier Zeitreihen wird definiert, daß zwischen ihnen bei Erhaltung der Autokorrelation kein höherer Zusammenhang besteht als nach dem Zufall zu erwarten.
N2  - The problem of examining the relation between two or more series of successive observations occurs often in the psychologieal and psychiatrie research. The usual methods of measuring covariation cannot be employed here, particularly because they cannot be used to draw inferences. The present paper describes a new method to examine the relation between autocorrelated series of successive observations, without using any presuppositions. Two successive series are considered to be independent, when the relation between them is not higher than that expected by chance. The method described here is based upon a paper by Pfanzagl (1963), and is illustrated with the help of an example from the field of Pharmacopsychology.

T1  - Juristic thought and psychology: A relation of interdependence
N2  - Traditionally psychological research had assisted (de lege lata and de lege ferenda) jurisdiction, legislation, and law enforcement. However, the fol1owing three examp1es support the thesis that certain areas of psycho1ogica1 research gain new concepts and hypotheses by considering re1ated juristic thought. First, a developmenta1 study on the judgment about neg1igent damages suggested a three-step deve10pment of the evaluation of neg1igence. That threestep development wou1d contradict Heider's sequence of responsibi1ity levels. Second, a cognitive algebra approach to asses the chi1d's understanding of the duty to compensate the victim for his 1055 caused by a culpab1e actor suggested a two-step deve10pment of understanding that duty. The chi1d of the first deve10pment a1 step wou1d regard giving on1y half compensation of the 10ss as doing his duty to repair damages. Third, the concept of cul pa and the "Strafzumes sungs 1 ehre" in the German juri 5 ti c thought are d i scussed as key concepts for innovating psycho1ogica1 research on a moral algebra. Insofar juristic thought proved to assist psycho1ogica1 theory bui1ding what would make the relation of juristic thought and psycho1ogy a relation of interdependence.

T1  - Binäre Kodierung von Sprechen und Blicken: Validität, Reliabilität und ihre Abhängigkeit von der zeitlichen Auflösung
N2  - Validität und Reliabilität der Sprechkodierung einer Beobachtergruppe wurden in Abhängigkeit von der zeitlichen Auflösung untersucht. Die Validität wurde anhand der Übereinstimmung der Beobachter mit einem automatischen Sprachdetektor berechnet. Die Reliabilitätswerte für die Kodierung von Sprechen und Blikken ergaben sich aus der Übereinstimmung der Beobachter untereinander. Im wesentlichen zeigten sich folgende Ergebnisse: 1. Die Validität/Reliabilität der Sprechkodierung ist eine monotone, nichtlineare Funktion der gewählten Auflösung. Die systematischen Fehler, die auf Latenz und Trägheit der menschlichen Beobachter zurückgehen, werden bei einer Auflösung von 400 msec nahezu vollständig unterdrückt. 2. Weder bei der Erfassung des Sprech- noch des Blickverhaltens lassen sich Anzeichen für Observer-Drift feststellen. Trainierte und untrainierte Beobachter unterscheiden sich nicht signifikant. 3. Die Kodierung des Sprechverhaltens ist geringfügig reliabler als die des Blickverhaltens. Dieser Unterschied kann in der Praxis vernachlässigt werden.
N2  - The reliability of the binary coding of speech and gaze was examined as a function of the temporal resolution of measurement. The reliability was calculated as the agreement between human observers. In addition, the validity of the speech coding could be determined from the agreement between the human observers and an electronic speech detector.

T1  - Structural organization of spacer chromatin between transcribed ribosomal RNA genes in amphibian oocytes
N2  - Transcribed nucleolar chomatin, including the spacer regions interspersed between the rRNA genes, is different from the bulk of nontranscribed chromatin in that the DNA of these regions appears to be in an extended (B) conformation when examined by electron microscopy. The possibility that this may reflect artificial unfolding of nucleosomes during incubation in very low salt buffers as routinely used in such spread preparations has been examined by studying the influence of various ion concentrations on nucleolar chromatin structure. Amplified nucleolar chromatin of amphibian oocytes (Xenopus laevis, Pleurodeles waltlii, Triturus cristatus) was spread in various concentrations of NaCl (range 0 to 20 mM). Below 1 mM salt spacer chromatin frequently revealed a variable number of irregularly shaped beads, whereas above this concentration the chromatin axis appeared uniformly smooth. At all salt concentrations studied, however, the length distribution of spacer and gene regions was identical. Preparations fixed with glutaraldehyde instead of formaldehyde, or unftxed preparations, were indistinguishable in this respect. The observations indicate that (i) rDNA spacer regions are not compacted into nucleosomal particles and into supranucleosomal structures when visualized at chromatin stabilizing salt concentrations (e.g., 20 mM NaCl), and (ii) spacer DNA is covered by a uniform layer of proteins of unknown nature which, at very low salt concentrations (below 1 mM NaCl), can artificially give rise to the appearance of small granular particles of approximately nucleosome-like sizes. These particles, however, are different from nucleosomes in that they do not foreshorten the associated spacer DNA. The data support the concept of an altered nucleohistone conformation not only in transcribed chromatin but also in the vicinity of transcriptional events.

T1  - DNA is assembled into globular supranucleosomal chromatin structures by nuclear contents of amphibian oocytes
N2  - The assembly of DNA into nucleosomal and supranucleosomal chromatin structures has been studied (i) by injection of circular DNA molecules (plasmids) into nuclei of Pleurodeles waltlii oocytes; and (ii) by in vitro incubation of plasmid molecules with the supernatant fraction from oocyte nuclei of Pleurodeles and Xenopus laevis, followed by purification of nucleoprotein structures formed with sucrose gradient centrifugation. [n both types of experiments , spread preparations of the newly assembled and transcriptionally inactive chromatin , examined by electron microscopy , show dense globular higher order (supranucleosomal) packing forms. Under partially relaxing (low salt) preparation conditions granular chromatin subunits of about 30 nm diameter can be seen either as widely spaced particles or in closely packed aggregates. The transcriptionally inactive endogenous chromatin of chromomeres of lampbrush chromosomes is arranged in similar higher order chromatin units. A correlation is found between the sizes of the DN A molecule probes used and the numbers of nucleosomes and higher order globules in the assembled chromatin structures. After prolonged dispersion in low salt buffers , these globular chromatin units unfold into chains of7-12 nucleosomes. The results support the concept that chromatin is arranged , under physiological ion concentrations as they are present in the nucleus , in supranucleosomal units of globular morphology.
