Implizite und explizite Botschaften in Karriereratgebern f��r Frauen

Many women, especially those with a higher level of education, are eager to prove themselves at work. Nowadays, more and more people turn to anonymous authorities, like therapists and professional coaches, to seek advice and help. Regarding this situation the article examines present career-advice books for women. A reconstructive approach allows to show implicit assumptions and hidden constructions of labour and gender. It unveils the inconsistencies behind the suggested advice given. Furthermore it can be shown how the presented instructions can lead to constant self-improvement and increased self-exploitation.     

Estimating sexual behavior parameters from routine sexual behavior data

In mathematical models for predicting the spread of sexually transmitted diseases (STDs), the rate of acquisition of new sex partners and concurrency, the number of simultaneous sexual partnerships, are important parameters. Yet, information on these parameters is rarely obtained in routine sexual behavior surveys; instead, questions about the total number of sex partners during specific periods are often asked. We present two methods that estimate the rate of partnership acquisition and concurrency from reported numbers of sex partners in two overlapping periods. The first method assumes homogeneous behavior, while the second method also takes account of heterogeneity in sexual behavior. Both methods assume random (Poisson) partnership acquisition and the possibility of overlap in relationships. For both methods it might be relevant to distinguish individuals who are in a stable relationship from those who are not.     

Auf den Rangplatz kommt es an – Wirkung der Rangfolge von Produkten auf das Entscheidungsverhalten

Customers often search for and choose from ordered sets. E. g., online shops present their product assortments as lists; very often the products are listed according to criteria as defined by the customers. Based on theoretical explanations it can be assumed that the rank of a product in a list effects its demand. An empirical study run in the market for used cars shows the importance of that effect. The study also reveals the most preferred rank and provides further insights for an optimal ordering of products. Furthermore, the understanding of individual decision about rank ordered products can be deepened.     

Attenuation of treatment effect due to measurement variability in assessment of progression-free survival

For normally distributed data analyzed with linear models, it is well known that measurement error on an independent variable leads to attenuation of the effect of the independent variable on the dependent variable. However, for time‐to‐event variables such as progression‐free survival (PFS), the effect of the measurement variability in the underlying measurements defining the event is less well understood. We conducted a simulation study to evaluate the impact of measurement variability in tumor assessment on the treatment effect hazard ratio for PFS and on the median PFS time, for different tumor assessment frequencies. Our results show that scan measurement variability can cause attenuation of the treatment effect (i.e. the hazard ratio is closer to one) and that the extent of attenuation may be increased with more frequent scan assessments. This attenuation leads to inflation of the type II error. Therefore, scan measurement variability should be minimized as far as possible in order to reveal a treatment effect that is closest to the truth. In disease settings where the measurement variability is shown to be large, consideration may be given to inflating the sample size of the study to maintain statistical power.

The magic in the (extra)ordinary: Intensive validation to recalibrate the life-worlds of adolescents exposed to abuse

This qualitative case study aimed to explore environmental circumstances and interactional processes that appeared to be relevant for the dynamics of resilience in adolescents exposed to child abuse. Fieldwork at a learning and coping centre for children and their families was combined with semi-structured interviews with adolescent participants aged 12 to 18 years. A critical realist approach was used to unpack what has been called the ‘ordinary magic’ of resilience. We found that intensively validating qualities of both the environment and relationships seemed to be driving components for resilience. Borrowing ideas from the sociometer theory, we propose that particularly the consistent intensiveness may offer a recalibration of the adolescents' immediate life-worlds, in terms of how they perceive the people they meet and the environments they step into. In keeping with the transactional-ecological model of resilience, we suggest that such a recalibration leads to altered social agency that becomes visible through their immediate social participation.
