Nice, but not smart? Attributional backlash from displaying prosocial behavior in the classroom
According to attributional theory, when the application of effort leads to success we praise the achievement. Effort and ability, however, are seen as compensatory and thus, paradoxically, being praised can lead to attributions of low ability. Our study investigates whether praise, not for academic performance, but for social classroom behavior, would also incur attributional backlash. We examined whether prosociality relates to attributions of high effort and low ability, mediated by expected teacher praise and happiness. In adolescence, prosocial behavior is displayed more by females and aligns with femininity. We conducted an experimental vignette study with 324 German ninth graders to examine whether prosocial students experience a denigration of achievement via expected teacher reaction. Multilevel modelling showed that compared to nondescript students, prosocial students were judged to receive good grades as a result of effort and less due to ability, but this was not related to expected teacher reactions. Prosocial students were also judged to be more likeable and popular. Examination of gender-related outcomes showed that prosocial students were believed to be more feminine, but also more masculine than the nondescript student. Female prosocial targets were thought to be more typical, but not as occurring more frequently than their male counterparts. The results are discussed in reference to the paradox of praise. The limitations and implications of the research are discussed, particularly regarding female studentsâ achievements
Instrumentality Gives Girls the Edge: Gender-Differential Relations Between Instrumentality, Achievement Motivation, and Self-Esteem
Gender differences in school are often discussed in reference to a particular type of masculinity, negative masculinity, which is often conceptualized as detrimental to success. Another type of masculinity, instrumentality, has rarely been studied in schools even though instrumental characteristics are often exalted outside the academic context. The current study focuses on potential benefits that students may reap from instrumentality. The extent to which an instrumental self-concept is directly and indirectly associated with achievement motivation and self-esteem was examined for adolescent boys and girls in a structural equation model (SEM). A sample of German ninth graders (Nâ=â355) completed self-report measures pertaining to their gender role self-concept, hope for success, fear of failure, and global and academic contingent self-esteem. The SEM revealed that instrumentality was associated with lower fear of failure and higher hope for success for both male and female adolescents. High scores in instrumentality were associated with greater self-esteem and lower academic contingent self-esteem. The association between instrumentality and global self-esteem was stronger for adolescent girls, and the indirect association between instrumentality and fear of failure through global self-esteem was significant only for girls. Results indicate that instrumentality can be an asset for students and that female students especially reap the benefits of an instrumental self-concept. The results are discussed in reference to the dangers of emphasizing solely the association between negative masculinity and academic failure, and the importance of studying relations with gender role self-concept separately for male and female adolescents
Anpassung der Barometrischen Prozess-Separation (BaPS) fĂŒr die Anwendung in kalkhaltigen Böden
Es wird ein neues Konzept zur Anpassung der Barometrischen Prozess-Separation (BaPS) an alkalische Bodenbedingungen vorgestellt und es werden erste vorlĂ€ufige Ergebnisse prĂ€sentiert. Das methodische Problem der BaPS in kalkhaltigen Böden besteht im zunehmenden Einfluss der CO2-Lösung in der Bodenlösung (Kalk-KohlensĂ€ure-Gleichgewicht) auf die Gasbilanzrechnungen. Dies wirkt sich auf die Bestimmung der C- und N- Umsatzraten aus. Anstelle den ?CO2aq-Term mit dem Massenwirkungsgesetz fĂŒr CO2 anzu-nĂ€hern, soll er nun mit der Fumigations-CO2-Injektions Methode experimentell bestimmt und charakterisiert werden
The 322 ka TiribĂ Tuff: stratigraphy, geochronology and mechanisms of deposition of the largest and most recent ignimbrite in the Valle Central, Costa Rica
The TiribĂ Tuff covered much of the Valle Central of Costa Rica, currently the most densely populated area in the country (âŒ2.4 million inhabitants). Underlying the tuff, there is a related well-sorted pumice deposit, the TibĂĄs Pumice Layer. Based on macroscopic characteristics of the rocks, we distinguish two main facies in the TiribĂ Tuff in correlation to the differences in welding, devitrification, grain size, and abundance of pumice and lithic fragments. The Valle Central facies consists of an ignimbritic plateau of non-welded to welded deposits within the Valle Central basin and the Orotina facies is a gray to light-bluish gray, densely to partially welded rock, with yellowish and black pumice fragments cropping out mainly at the Grande de TĂĄrcoles River Gorge and Orotina plain. This high-aspect ratio ignimbrite (1:920 or 1.1Ă10â3) covered an area of at least 820 km2 with a long runout of 80 km and a minimum volume outflow of 25 km3 (15 km3 DRE). Geochemically, the tuff shows a wide range of compositions from basaltic-andesites to rhyolites, but trachyandesites are predominant. Replicate new 40Ar/39Ar age determinations indicate that widespread exposures of this tuff represent a single ignimbrite that was erupted 322±2 ka. The inferred source is the Barva Caldera, as interpreted from isopach and isopleth maps, contours of the ignimbrite top and geochemical correlation (âŒ10 km in diameter). The TiribĂ Tuff caldera-forming eruption is interpreted as having evolved from a plinian eruption, during which the widespread basal pumice fall was deposited, followed by fountaining pyroclastic flows. In the SW part of the Valle Central, the ignimbrite flowed into a narrow canyon, which might have acted as a pseudo-barrier, reflecting the flow back towards the source and thus thickening the deposits that were filling the Valle Central depression. The variable welding patterns are interpreted to be a result of the lithostatic load and the influence of the content and size of lithic fragments

Plant health and global change - some implications for landscape management
Global change (climate change together with other worldwide anthropogenic processes such as increasing trade, air pollution and urbanization) will affect plant health at the genetic, individual, population and landscape level. Direct effects include ecosystem stress due to natural resources shortage or imbalance. Indirect effects include (i) an increased frequency of natural detrimental phenomena, (ii) an increased pressure due to already present pests and diseases, (iii) the introduction of new invasive species either as a result of an improved suitability of the climatic conditions or as a result of increased trade, and (iv) the human response to global change. In this review, we provide an overview of recent studies on terrestrial plant health in the presence of global change factors. We summarize the links between climate change and some key issues in plant health, including tree mortality, changes in wildfire regimes, biological invasions and the role of genetic diversity for ecosystem resilience. Prediction and management of global change effects are complicated by interactions between globalization, climate and invasive plants and/or pathogens. We summarize practical guidelines for landscape management and draw general conclusions from an expanding body of literature
