Die Öffentliche Zuschreibung von Verantwotung

Whether actors failed or succeeded in their political efforts, even who is in charge of finding solutions in the first place, depends on the public attribution of responsibility. The attribution of responsibility is one of the key elements of public discourse. However, social sciences by now failed to provide an instrument for systematic content analysis concerning attribution statements. The article presents an instrument which was developed for the systematic coding of claims on responsibility. Firstly, we give an overview on content analysis methods both, quantitative and qualitative. Secondly, we unfold our concept. We define a statement of responsibility attribution as consisting of three parts: the attribution sender (a), who directs a claim of responsibility at the attribution addressee (b) concerning a specified issue (c). This basic concept is further differentiated. In the final section we report our experiences during the coding phase.     

Initiating Sexual Experiences: How Do Young Adolescents Make Decisions Regarding Early Sexual Activity?

Understanding how young adolescents make decisions to engage in early sexual activities is vital for intervention efforts aimed at fostering positive youth development and reducing the negative outcomes of adolescent sexual behavior. In‐depth interviews with 42 suburban, mostly White, ninth‐grade adolescents (52% females, mean age=14.1, SD=.45) elicited accounts of their early sexual decisions. We adapted grounded theory methodology to build a model of sexual decision making from the adolescents' narratives. Six dominant categories emerged: contextual factors (relationship and personal characteristics), consideration of risks and benefits, boundary setting, boundary communication, the sexual experience, and evaluation. Our model of early sexual decision‐making processes, developed from the perspectives of young adolescents, highlights active consideration of health and social risks and benefits, as well as the generation of options regarding sexual activity. The model also shows that young adolescents set clear boundaries of sexual limits and evaluate sexual experiences, suggesting a dynamic process of decision making.     

Online bin packing of fragile objects with application in cellular networks

We study a specific bin packing problem which arises from the channel assignment problems in cellular networks. In cellular communications, frequency channels are some limited resource which may need to share by various users. However, in order to avoid signal interference among users, a user needs to specify to share the channel with at most how many other users, depending on the user’s application. Under this setting, the problem of minimizing the total channels used to support all users can be modeled as a specific bin packing problem as follows: Given a set of items, each with two attributes, weight and fragility. We need to pack the items into bins such that, for each bin, the sum of weight in the bin must be at most the smallest fragility of all the items packed into the bin. The goal is to minimize the total number of bins (i.e., the channels in the cellular network) used. We consider the on-line version of this problem, where items arrive one by one. The next item arrives only after the current item has been packed, and the decision cannot be changed. We show that the asymptotic competitive ratio is at least 2. We also consider the case where the ratio of maximum fragility and minimum fragility is bounded by a constant. In this case, we present a class of online algorithms with asymptotic competitive ratio at most of 1/4+3r/2, for any r>1.

Rationales Effektivitätstraining als Coaching-Methode für Führungskräfte

The Rational Effectiveness Training (RET) had been developed on the basis of the therapy approach of REBT according to Albert Ellis. In the following article the author shows, that the RET corresponds to the criteria of a coaching method. In addition she recommends to attach importance to the interpersonal and systemic perspective. Considering as case study of a newly nominated supervisor the RET has been applied.     

Assessing goodness-of-fit for evaluation of dose-proportionality

For the clinical development of a new drug, the determination of dose-proportionality is an essential part of the pharmacokinetic evaluations, which may provide early indications of non-linear pharmacokinetics and may help to identify sub-populations with divergent clearances. Prior to making any conclusions regarding dose-proportionality, the goodness-of-fit of the model must be assessed to evaluate the model performance. We propose the use of simulation-based visual predictive checks to improve the validity of dose-proportionality conclusions for complex designs. We provide an illustrative example and include a table to facilitate review by regulatory authorities.     

Ethnic Diversity and Inequality in Sub-Saharan Africa: Do Institutions Reduce the Noise?

Studies on the causes of income differences between the rich and the poor have received an extensive attention in the inequality empirics. While ethnic diversity has also been identified as one of the fundamental causes of income inequality, the role of institutions as a mediating factor in the ethnicity-inequality nexus has not received the scholarly attention it deserves. To this end, this study complements the existing literature by investigating the extent to which institutional framework corrects the noisy influence originating from the nexus between “ethnic diversity” and inequality in 26 sub-Saharan African countries for the period 1996–2015. The empirical evidence is based on pooled OLS, fixed effects and system GMM estimators. The main findings reveal that the mediating influences of institutional settings are defective, thus making it extremely difficult to modulate the noisy impacts of ethno-linguistic and religious heterogeneity on inequality. In addition, the negative influences orchestrated by ethno-linguistic and religious diversities on inequality fail to attenuate the impact of income disparity even when interacted with institutions. On the policy front, institutional reforms tailored toward economic, political and institutional governances should be targeted.

     

Challenging implicit bias: preparing students to practice with African American families

ABSTRACT

The disparity of African American families in the foster care system is a concern in the field of child welfare services and the social work profession. African American families experience unique challenges related to discriminatory practices and implicit biases in the child welfare system and by mandated reporters. To address these inequalities, state and local agencies have implemented prevention and intervention services to support minority families. Additionally, child welfare agencies have invested in professional development training for their workers to alleviate possible intolerant practices. This article describes implicit biases and considers how they could contribute to the disparity of African American families involved in the child welfare system. Furthermore, the article presents approaches to help social work students to identify and challenge their implicit biases to support culturally sensitive practices while working with African American families. It concludes with implications for social work education.
