Diasporic youth identities of uncertainty and hope: second-generation Albanian experiences of transnational mobility in an era of economic crisis in Greece

This paper explores various dimensions of ‘gender’ and ‘mobility’ among immigrant youth from a transnational perspective in an era of economic crisis. The extent and parameters of continuity, contestation and change in migrant youth identities are analysed and we suggest that neither gender nor identity are stable categories but are embedded in sociocultural particularities both in the country of residence (Greece) but also in the country of origin (Albania). Through in-depth interviews with 52 participants, all second-generation Albanian immigrants in Greece born to two Albanian parents, the paper addresses youth identification in relation to gendered representations of belonging. The narrative accounts that we have selected and analysed reflect the emotional challenges, constraints and creativity of Albanian youth.     

The role of weighting in corporate governance ratings

This methodological paper highlights the differences and the resulting implications from the application of the three most commonly applied weighting index methods to measuring corporate governance quality at an aggregate level: the Dichotomous; the partial compliance (PC) unweighted; and the Experts’ methods. In particular, first, we demonstrate how each method is applied and provide the details needed for readers to replicate each method. Second, we employ these methods on a sample of companies and compare the corresponding scores by testing their differences statistically. Third, as an indicative example of the potential implications arising from the use of these measures, we test whether the relation between market value and corporate governance levels differs, depending on the method applied. We find that the three methods produce significantly different overall and relative (i.e., ranking order) scores and, consequently, the relation between market value and corporate governance levels differs, depending on the method applied. Thus, we contribute to the corporate governance literature by showing that weighting in corporate governance indices matters and we recommend simultaneous application of at least two methods (i.e., the PC unweighted and the Experts’ methods) for deriving robust findings.

A folded model for compositional data analysis

A folded type model is developed for analysing compositional data. The proposed model involves an extension of the α‐transformation for compositional data and provides a new and flexible class of distributions for modelling data defined on the simplex sample space. Despite its rather seemingly complex structure, employment of the EM algorithm guarantees efficient parameter estimation. The model is validated through simulation studies and examples which illustrate that the proposed model performs better in terms of capturing the data structure, when compared to the popular logistic normal distribution, and can be advantageous over a similar model without folding.     

Nonparametric hypothesis testing for equality of means on the simplex

We investigate use of empirical and exponential empirical likelihood, and Hotelling and James statistics, to test the null hypothesis of equal population means based on two independent samples of data on the simplex. We perform an extensive numerical study using data simulated from various distributions on the simplex. The results, taken together with practical considerations regarding implementation, support the use of bootstrap-calibrated James statistic.     

A comparative study of urban fragmentation patterns in small and mid-sized cities of Idaho

Urbanization has a massive impact on ecological function and impedes the provisioning of environmental services. The interaction between urbanization and the environment has been researched extensively. However, the existing research focused on the urbanization characteristics of large metropolitan areas. In this paper, we investigate the urban fragmentation patterns of small and mid-sized cities in Idaho, USA. To capture the urban morphology for each site within the study we use both concentric ring and transect analysis as well as several spatial/landscape metrics. Our results show that the characteristics of urbanization in small and mid-sized cities (and those in second-tier regions that attract relatively little scholarly attention) are consistent with growth phase theory of urbanization, urbanization along a gradient, and urbanization patterns of metropolises.     

Exploring the distribution for the estimator of Rosenthal's ‘fail-safe’ number of unpublished studies in meta-analysis

The present article discusses the statistical distribution for the estimator of Rosenthal's ‘file-drawer’ number N_R, which is an estimator of unpublished studies in meta-analysis. We calculate the probability distribution function of N_R. This is achieved based on the central limit theorem and the proposition that certain components of the estimator N_R follow a half-normal distribution, derived from the standard normal distribution. Our proposed distributions are supported by simulations and investigation of convergence.     

Child‐led research in the context of Australian social welfare practice

This paper details the first child‐led research programme to be implemented in Australia in which children design and lead their own research about issues they identify. The programme was specifically adapted for children who were service users of a nongovernment organization that provides social welfare and support services to vulnerable children and their families, living in communities of the disadvantaged. The practitioner – researchers faced the expected challenges of power in child–adult relations pertinent to the status of children in a genuinely child‐led research endeavour. However, the paper details the additional challenges and responses required when conducting research in a practice environment and the successful adaptations that were used to meet these challenges. The positive findings of an independently commissioned programme evaluation raise important questions about the place and purpose of child‐led research within the field of children's social welfare practice.
