Undutiful daughter(s): troubling geographies of the gendered nation and belonging in Adichie’s Americanah and Atta’s Everything Good Will Come

ABSTRACT

This paper proffers a reading of Chimamanda Ngozi Adichie’s Americanah as a Bildungsroman that represents a moment of a daughter’s “undutifulness” to domesticating national patriarchies and cultures, textual and epistemic genealogies. In this regard, I posit Adichie’s twining of national romances and a heterosexual romantic love that travels and returns as a framework for examining gendered experiencing and relations to the “home.” The article considers the text’s representation of migration and return not simply as moments of re-domestication and formulaic reunification but as incidents that enunciate expanded relationalities to the nation and reconfigure domestic intimacies in a manner that radically unsettles “home.” Americanah is read alongside Sefi Atta’s Everything Good Will Come in an attempt to show how the development of the protagonists’ interpersonal romances goes together with a studied engagement with the national space and communities in ways that inscribe women’s labours of love, care and intellect into the public domain and charts transformative possibilities of being in the world and inhabiting home. Ultimately, Adichie and Atta’s texts demonstrate alertness to celebrations of transnational black femininities, its vulnerabilities and bonds that transcend the limited “ethical” commitments delineated by the horizons of gendered roles and the national home.     

Model-based potential analysis of the distribution logistics: a case study

Abstract

The design of its distribution logistics has a decisive influence on a company’s logistical costs and performance. They therefore make an essential contribution to corporate success. This article describes a method for analysing the potential of distribution logistics in terms of logistical costs and performance. In contrast to previous procedures of business process re-engineering, this method maps distribution logistics holistically under variable distribution structures. The article is focused on the approach and results of a case study in a multinational manufacturer of propulsion and automation technologies for machine construction and systems engineering. The developed method is distinguished by a high degree of practicality and applicability. It will contribute to a more efficient design of distribution logistics.     

A Review of Recent Advances in Benchmark Dose Methodology

In this review, recent methodological developments for the benchmark dose (BMD) methodology are summarized. Specifically, we introduce the advances for the main steps in BMD derivation: selecting the procedure for defining a BMD from a predefined benchmark response (BMR), setting a BMR, selecting a dose–response model, and estimating the corresponding BMD lower limit (BMDL). Although the last decade has shown major progress in the development of BMD methodology, there is still room for improvement. Remaining challenges are the implementation of new statistical methods in user‐friendly software and the lack of consensus about how to derive the BMDL.     

Maximum likelihood estimation for the generalized poisson distribution when sample mean is larger than sample variance

The generalized Poisson distribution (GPD), studied by many researchers and containing two parameters θ and λ, has been found to fit very well data sets arising in biological, ecological, social and marketing fields. Consul and Shoukri (1985) have shown that for negative values of λ the GPD gets truncated and the model becomes deficient; however, the truncation error becomes less than 0.0005 if the minimum number of non-zero probability classes ≥ 4 for all values of θ and λ and the GPD model can be safely used in all such cases. The problem of admissible maximum likelihood (ML) estimation when the sample mean is larger than the sample variance is considered in this paper which complements the earlier work of Consul and Shoukri (1984) on the existence of unique ML estimators of θ and λ when the sample mean is smaller than or equal to the sample variance.     

Parental Presence and Encouragement Do Not Influence Helping in Young Children

Young children begin helping others with simple instrumental problems from soon after their first birthdays. In previous observations of this phenomenon, both naturalistic and experimental, children’s parents were in the room and could potentially have influenced their behavior. In the two current studies, we gave 24‐month‐old children the opportunity to help an unfamiliar adult obtain an out‐of‐reach object when the parent (or a friendly female adult) (i) was present but passive, (ii) was present and highlighted the problem for the child, (iii) was present and actively encouraged the child to help, (iv) was present and ordered the child to help, or (v) was absent from the room. The children helped at relatively high levels and equally under all these treatment conditions. There was also no differential effect of treatment condition on children’s helping in a subsequent test phase in which no parent was present, and children had to disengage from a fun activity to help. Young children’s helping behavior is not potentiated or facilitated by parental behavior in the immediate situation, suggesting that it is spontaneous and intrinsically motivated.     

Die Bewertung von Verlustvorträgen und Tax Shields auf arbitragefreien Märkten

In this paper, the value of tax loss carryforwards is calculated using a modified arithmetic brownian motion for the taxable base. A formula for valuing tax loss carryforwards within a one period context is derived. A Monte-Carlos Simulation based on our findings leads to a valuation of tax loss carryforwards in a multiperiod setting and yields reasonable results. The methodology can also be used to value tax shields in a situation with an interest barrier as it is the case in the German tax system.
