On Families of Distributions with Shape Parameters

Univariate continuous distributions are one of the fundamental components on which statistical modelling, ancient and modern, frequentist and Bayesian, multi‐dimensional and complex, is based. In this article, I review and compare some of the main general techniques for providing families of typically unimodal distributions on with one or two, or possibly even three, shape parameters, controlling skewness and/or tailweight, in addition to their all‐important location and scale parameters. One important and useful family is comprised of the ‘skew‐symmetric’ distributions brought to prominence by Azzalini. As these are covered in considerable detail elsewhere in the literature, I focus more on their complements and competitors. Principal among these are distributions formed by transforming random variables, by what I call ‘transformation of scale’—including two‐piece distributions—and by probability integral transformation of non‐uniform random variables. I also treat briefly the issues of multi‐variate extension, of distributions on subsets of and of distributions on the circle. The review and comparison is not comprehensive, necessarily being selective and therefore somewhat personal. © 2014 The Authors.

Asymptotic distributions of φ-divergences of hypothetical and observed frequencies on refined partitions

For a wide class of goodness-of-fit statistics based on φ-divergences between hypothetical cell probabilities and observed relative frequencies, the asymptotic normality is established under the assumption n / m _n →γ∈(0,∞), where n denotes sample size and m _n the number of cells. Related problems of asymptotic distributions of φ-divergence errors, and of φ-divergence deviations of histogram estimators from their expected values, are considered too.     

Governing ‘Sustainable Urban Development’ Through Self‐Build Groups and Co‐Housing: The Cases of Hamburg and Gothenburg

This article critically examines the governing of ‘sustainable urban development’ through self‐build cohousing groups in Gothenburg and Hamburg. The two case cities have been selected because both are currently involved in major urban restructuring, and have launched programmes to support self‐build groups and cohousing as part of their emphasis on promoting urban sustainable development through this process. Departing from a theoretical discussion on advanced liberal urban governance, focusing in particular on the contemporary discourse on sustainable urban development, we examine the interaction between political institutions, civil society and private actors in the construction of cohousing as a perceived novel and alternative form of housing that may contribute to fulfilling certain sustainability goals. Questions centre on the socio‐political contextualization of cohousing; concepts of sustainability; strategies of, and relations between, different actors in promoting cohousing; gentrification and segregation; and inclusion and exclusion. In conclusion we argue that, while self‐build groups can provide pockets of cohousing as an alternative to dominant forms of housing, the economic and political logics of advanced liberal urban development make even such a modest target difficult, particularly when it comes to making such housing affordable.     

‘The City of Our Dream’: Owambe Urbanism and Low‐income Women's Resistance in Ibadan,Nigeria

Ibadan, Nigeria, has been an outlier in the ranking of world‐class cities. But in the past seven years, amidst the circulating Africa Rising narrative, Ibadan has embarked on what I call an Afropolitan Imagineering project of owambe urbanism. Afropolitan Imagineering refers to the production of new images/narratives of Africa and Africans as world‐class and cosmopolitan. Owambe urbanism is a spatio‐temporal neoliberal project concerning destination, arrival and place‐making, which promises a shared and happy future for all urban dwellers. I argue that this promise of happiness is challenged by low‐income women who are cognizant that a shared and happy future is impossible when little effort is made to address social inequality in the present. They thus refuse to be ‘good’ citizens and invoke an alternative urban futurity through their embodied and imagined resistance.     

Corporate Responsibility Reporting and its Determinants in Comparative Perspective – a Review of the Empirical Literature and a Meta‐analysis

For four decades, reporting on corporate responsibility by businesses has been the subject of empirical research. In the 1970s and 1980s, studies mostly originated from Anglo‐Saxon and Western European countries. During the last two decades research on responsibility reporting was increasingly undertaken in emerging and developing countries as well – always following the reporting practices of the respective businesses. Consequentially, a very large number of studies exist today. Many of these have empirically investigated the determinants of responsibility reporting and examined whether internal factors like size and industry or external factors like stakeholder pressures have an impact on disclosure. Thus, the purpose of the following paper is twofold. First, it seeks to provide an overview of the existing literature in order to facilitate further research. Overall, 186 studies have been examined for the determinants which they considered and have been grouped according to their geographical origin. This provides for an analysis of whether academics from different regions have taken different approaches to the empirical examination of responsibility reporting and if their results differed. The findings show that scholars across regions have taken different paths in empirical research, but indications for a variation in the impact of specific determinants on reporting are weak.

Managing the Intangible Aspects of a Project: The Affect of Vision,Artifacts, and Leader Values on Project Spirit and Success in Technology‐Driven Projects

Successful projects are often characterized by a unique spirit. Phase one results, based on 193 employees partaking in 60 projects across organizations, support a model positing that leader building activities affect employees' emotions, attitudes, and behavioral norms that are focused on expected project outcomes, termed project spirit. Spirit affects employees' contextual performance behavior, which in turn affects success as proposed. Phase two cases, designed to ground these results in technology‐driven project contexts, highlight the value of managing the project's intangible aspects captured by spirit. Quantitative and qualitative findings imply that leaders can be coached to execute behaviors that generate a project's spirit, which boosts contextual performance behavior and increases project success.     

Being Good Parents or Being Good Citizens: Dilemmas and Contradictions of Urban Families in Middle‐Class Enclaves and Mixed Neighbourhoods in Germany

In recent years, cities have become ever more attractive to middle‐class families. On the one hand, middle‐class families tend to withdraw into (often newly built) socially homogeneous middle‐class neighbourhoods. On the other hand, they are also known to move into inner‐city and socially mixed areas, thus triggering processes of gentrification. Academic literature has often denounced these housing choices as being either ‘separatist’ or ‘revanchist’, more broadly categorized as strategies of ‘middle‐class disaffiliation’. Although there is a grain of truth in these interpretations, the reality is certainly more complicated. In our research on middle‐class parents’ housing and neighbourhood choices as well as their patterns of neighbourhood use, carried out in each of the two types of residential area mentioned above, we have only very rarely found an explicit desire to draw boundaries that exclude those ‘beneath’ them. We rather argue that the housing choices and neighbourhood‐related activities of middle‐class family households are heavily influenced by the specific dilemmas the interviewees face as (working) urban parents. While a significant number of respondents worry about the social sustainability, justice and cohesion of urban society, they are also concerned about the future prospects of their children. Many find it difficult to reconcile these conflicting normative demands under the prevailing circumstances.
