Estimating Box-Cox power transformation parameter via goodness-of-fit tests

Box–Cox power transformation is a commonly used methodology to transform the distribution of the data into a normal distribution. The methodology relies on a single transformation parameter. In this study, we focus on the estimation of this parameter. For this purpose, we employ seven popular goodness-of-fit tests for normality, namely Shapiro–Wilk, Anderson–Darling, Cramer-von Mises, Pearson Chi-square, Shapiro-Francia, Lilliefors and Jarque–Bera tests, together with a searching algorithm. The searching algorithm is based on finding the argument of the minimum or maximum depending on the test, i.e., maximum for the Shapiro–Wilk and Shapiro–Francia, minimum for the rest. The artificial covariate method of Dag et al. (2014) is also included for comparison purposes. Simulation studies are implemented to compare the performances of the methods. Results show that Shapiro–Wilk and the artificial covariate method are more effective than the others and Pearson Chi-square is the worst performing method. The methods are also applied to two real-life datasets. The R package AID is proposed for implementation of the aforementioned methods.     

Local Moral Economies: The Space,Place, and Locality of Social Media Mobilisation

This study is a case study of a locally rooted environmental campaign on the Swedish island of Gotland. We aim to enhance the understanding of how locality is manifested in social movements that emerge in today’s networked world. We analyse how the double goals of speaking to, as well as beyond, the local context came into expression in the movement’s social media activities. We draw on data from tweets and Facebook posts and include interactions between activists and critics as well as the resources linked to in the posts. Analysis indicates that the conflict must be seen as spanning across local, national and global levels. In line with earlier research, activists used social media to link their struggle with other struggles. Also, it was used to charge the local struggle with symbolic content by framing it as one of many struggles between local communities, authorities and multinational corporations. Beyond this, posts from the island signalled dedication to the history and long-term interests of the community. We argue that future studies should recognise the crucial role that reciprocity norms in the local community can play for outcomes of conflicts and that the notion of a ‘local moral economy’ can be used to reach a deeper understanding of this.     

Feminist Politics in Contemporary Turkey: Neoliberal Attacks,Feminist Claims to the Public

This article aims to offer a critical reading of the feminist claims to the public sphere in Turkey in the 2000s when there was transformation in the way public and private spheres are defined. We try to link the feminist claims to the public with the shifts in the patriarchal regime of the country in the decade. The main argument of the article is that feminist politics of the 2000s had the potential for an alternative imagination of the public and that they also faced the risk of assimilation into the de-/re-publicization process of the same period. The article starts with a brief outline of the post-1980 period, which hosted both the emergence of independent feminist organizing and the neoliberal restructuration of Turkey’s politics. It continues with the analysis of the Justice and Development Party’s terms in government, as the consolidation of neoliberal restructuration process. We conclude with the (possible) feminist interventions to the new mode of patriarchy that emerges out of this process.     

On the BLUEs in Two Linear Models via C. R. Rao's Pandora's Box

We consider the estimation of the parameters in two partitioned linear models, denoted by 𝒜 = {y, X ₁ β ₁ + X ₂ β ₂, V _𝒜} and ? = {y, X ₁ β ₁ + X ₂ β ₂, V _?}, which we call full models. Correspondingly, we define submodels 𝒜₁ = {y, X ₁ β ₁, V _𝒜} and ?₁ = {y, X ₁ β ₁, V _?}. Using the so-called Pandora's Box approach introduced by Rao (1971 Rao , C. R. ( 1971 ). Unified theory of linear estimation . Sankhy?, Ser. A 33 : 371 – 394 . [Corrigendum (1972), 34, p. 194, 477.]  [Google Scholar], we give new necessary and sufficient conditions for the equality between the best linear unbiased estimators (BLUEs) of X ₁ β ₁ under 𝒜₁ and ?₁ as well as under 𝒜 and ?. In our considerations we will utilise the Frisch–Waugh–Lovell theorem which provides a connection between the full model 𝒜 and the reduced model 𝒜 _r  = {M ₂ y, M ₂ X ₁ β ₁, M ₂ V _𝒜 M ₂} with M ₂ being an appropriate orthogonal projector. Moreover, we consider the equality of the BLUEs under the full models assuming that they are equal under the submodels.     

Narrative and identity in Alzheimer's disease: A case study

In this case study, focus is on how persons with AD use their remaining linguistic and cognitive resources, together with non-verbal aspects of the storytelling event, as resources in communicating and negotiating their identities in everyday encounters. The results of the analysis, focusing on the telling of the stories, indicate that other aspects than the temporal and referential organization of the narratives has become important resources for the teller in establishing and negotiating identity. The telling of temporally discontinuous narratives does not appear to affect or disrupt the teller's experience of some sort of a continuous sense of self and identity but are probably more a problem to persons without this kind of diagnosis. Being afflicted by AD most likely leads persons to try to invent and use alternative communicative recourses in order to sustain factors like their senses of self and identities. For researchers this makes it important to try to base their analysis on the actual organization of the talk and to focus on the functions of various responses and utterances in the interaction.     

The changing relationship between unemployment and total fertility

The aim of this paper is to investigate whether there has been a fundamental change in the relationship between economic conditions and fertility. We use panel data methods to study the short-term changes in total fertility and the unemployment rate in a range of Organisation for Economic Co-operation and Development (OECD) countries from 1957 to 2014. We find that although fertility was counter-cyclical before 1970, with good economic times being associated with lower fertility, since then it has become pro-cyclical, with good economic times being associated with higher fertility.     

Gender Inequalities in Academic Innovation and Enterprise: A Bourdieuian Analysis

This paper demonstrates that engagement in innovation and enterprise activity in SET departments within three UK universities is, in part, gendered. A Bourdieuian approach is adopted to identify underlying structures and practices that have causal powers to generate gender‐based inequalities. Drawing on empirical research with 52 participants, this study reveals gendered science enterprise experiences, characterized by a field that is considered strong in shaping the habitus and presenting stark options to women in pursuit of their careers. It demonstrates the multilayered nature of the fields that shape gendered experiences and resultant inequalities by taking into account individual dispositions of academics and their habitus, including their science enterprise experience and the wider commercial field beyond the university, and generates a number of implications for practice and policy.
