Mother-Daughter Relationships in Young Adult Literature: A Content Analysis of Adolescent Individuation

This study describes a content analysis of young adult literature. Eight novels were selected and examined in regards to mother-daughter relationships and the presentation of daughters' individuation. The focus of this paper is the presence of emotional separation due to daughters' wishes to be independent from mothers. Based on the findings, novels in young adult literature do not present the process of individuation for adolescent daughters; rather, characters are either fully individuated at the start of the narrative or they struggle to begin their self-actualization throughout the novel. While daughters begin their individuation, their emotional evolutions are marked by strained relationships with their mothers

Einfluss langjähriger differenzierter K-Gehalte auf Parameter des Bodenwasserhaushaltes

Auf Basis langjähriger K-Steigerungsversuche aus Deutschland, Tschechien und Ungarn wurde der Einfluss unter-schiedlicher Bodenkaliumgehalte auf die Wasserbindung untersucht. Mit Steigerung der Kaliumgehalte nahmen dabei die Feldkapazität und die nutzbare Feldkapazität zu. Durch die K-Aufdüngung von K-Nullstufen vergleichbarer Böden wurde nachgewiesen, dass diese Effekte auf die langjährige Akkumulation der organi-schen Bodensubstanz infolge der er-tragssteigernden K-Wirkung zurückzuführen sind und weniger auf der kurzzeitigen Erhöhung der K-Gehalten basieren

Towards a “Sample-In, Answer-Out” Point-of-Care Platform for Nucleic Acid Extraction and Amplification: Using an HPV E6/E7 mRNA Model System

The paper presents the development of a “proof-of-principle” hands-free and self-contained diagnostic platform for detection of human papillomavirus (HPV) E6/E7 mRNA in clinical specimens. The automated platform performs chip-based sample preconcentration, nucleic acid extraction, amplification, and real-time fluorescent detection with minimal user interfacing. It consists of two modular prototypes, one for sample preparation and one for amplification and detection; however, a common interface is available to facilitate later integration into one single module. Nucleic acid extracts (n = 28) from cervical cytology specimens extracted on the sample preparation chip were tested using the PreTect HPV-Proofer and achieved an overall detection rate for HPV across all dilutions of 50%–85.7%. A subset of 6 clinical samples extracted on the sample preparation chip module was chosen for complete validation on the NASBA chip module. For 4 of the samples, a 100% amplification for HPV 16 or 33 was obtained at the 1 : 10 dilution for microfluidic channels that filled correctly. The modules of a “sample-in, answer-out” diagnostic platform have been demonstrated from clinical sample input through sample preparation, amplification and final detection

Are we failing to protect threatened mangroves in the Sundarbans world heritage ecosystem?

The Sundarbans, the largest mangrove ecosystem in the world, is under threat from historical and future human exploitation and sea level rise. Limited scientific knowledge on the spatial ecology of the mangroves in this world heritage ecosystem has been a major impediment to conservation efforts. Here, for the first time, we report on habitat suitability analyses and spatial density maps for the four most prominent mangrove species - Heritiera fomes, Excoecaria agallocha, Ceriops decandra and Xylocarpus mekongensis. Globally endangered H. fomes abundances declined as salinity increased. Responses to nutrients, elevation, and stem density varied between species. H. fomes and X. mekongensis preferred upstream habitats. E. agallocha and C. decandra preferred down-stream and mid-stream habitats. Historical harvesting had negative influences on H. fomes, C. decandra and X. mekongensis abundances. The established protected area network does not support the most suitable habitats of these threatened species. We therefore recommend a reconfiguration of the network to include these suitable habitats and ensure their immediate protection. These novel habitat insights and spatial predictions can form the basis for future forest studies and spatial conservation planning, and have implications for more effective conservation of the Sundarbans mangroves and the many other species that rely on them
