Die Vermittlung des heimlichen Lehrplans im Klassenraum : - Beobachtungen zu genderspezifischen Interaktionen mittels experimentellem Design

Der heimliche Lehrplan beschreibt soziale Werte, Normen und Regeln, welcher als Sozialisationsprozess den Schulalltag beeinflusst. Die eigens für die Thesis erstellten Hypothesen fragen nach der Validität der Methode sowie genderspezifischen Interaktionen. Schwerpunkt dieser Bachelor-Thesis sind Beobachtungen in zwei Sekundarschulen. Das Untersuchungsdesign ist experimentell an den Erhebungsbogen von zwei amerikanischen Wissenschaftlerinnen aus dem Jahr 1993 angelehnt. Nach einer Pretestphase sowie Modifizierungsprozess wurde das gewonnene Material quantitativ mithilfe des SPSS-Programms und qualitativ durch die Inhaltsanalyse aufbereitet und ausgewertet. Die Hypothesen werden durch die Auswertung und mithilfe von Gütekriterien beantwortet, sodass die Methodenvalidität größtenteils belegt werden kann. Tendenzen für geschlechterspezifische Interaktionen sind erkennbar, allerdings schwer zu generalisieren. Im Fazit wird die Bedeutung des heimlichen Lehrplans sowie die Geschlechtergerechtigkeit in Schulen diskutiert.

Morphological characterization and sex-related differences of the mandible of the armadillos Chaetophractus vellerosus and Zaedyus pichiy (Xenarthra, Dasypodidae), with consideration of dietary aspects

The morphological characteristics of the mandible of adult Chaetophractus vellerosus (Gray, 1865) and Zaedyus pichiy (Desmarest, 1804) were studied to establish its generalized design and to identify inter- and intra- (sexual) specific differences. Morphological descriptions were complemented with the application of univariate and multivariate (analysis of correlation matrices, PCA, discriminant analysis) techniques. The mandible of both species is very similar, and is characterized by elevated condyle, well developed angular process, distinct coronoid process, tooth row which extends to the rear end of the angle between body and ramus, and unfused but firm symphysis. Although both armadillos are omnivorous, a more slender configuration of the jaw in Z. pichiy could be indicative of a better adaptation of its masticatory apparatus to insectivory. The PCA showed an almost total segregation of both species on PC1 (47.7% of the total variance), with C. vellerosus being associated to mandibles taller and with wider body and ramus. Zaedyus pichiy was characterized by heavy loadings of length parameters on PC2 (22.6% of the variance). A small degree of sexual dimorphism was found, with size-based differences in C. vellerosus (larger mandibles in females) and shape-based differences in Z. pichiy (taller mandibles in males, longer ones in females). Correlations between variables were higher in males of both species, indicating a more stable shape of the mandible than in females. The selected parameters to discriminate sexes were the body length of the mandible in C. vellerosus (correct classification: ca. 86% in males, 81% in females), and the height of the mandible at the level of the last tooth in Z. pichiy (near 85% of right assignment in both sexes). The inclusion of a new variable (body length) in the latter species improved the classification of the females to 100%. Teeth are typically 10 in C. vellerosus and 9 in Z. pichiy, but aberrancies in this basic number, such as unilateral or bilateral extra or fewer teeth, are common.

On the design of peer punishment experiments

We discuss how technologies of peer punishment might bias the results that are observed in experiments. A crucial parameter is the “fine-to-fee” ratio, which describes by how much the punished subjects income is reduced relatively to the fee the punishing subject has to pay to inflict punishment. We show that a punishment technology commonly used in experiments embeds a variable fine-to-fee ratio and show that it confounds the empirical findings about why, whom, and how much subjects punish.
