Guest Editor's Introduction

Classical social theory in the Western tradition concerned itself with the history of the human condition and sought answers to big questions such as the meaning of change and progress. They were interested in the nature, origins and consequences for human life of modern society, with its new means of organizing production as well as legal and political arrangements. Contrary to the optimism of the Enlightenment with its unbounded faith in the ability of reason and scientific inquiry to liberate humans from domination by both religion and nature, classical social theorists saw the negative side of modern civilization. This can be summarized in terms of the loss of freedom or the enslavement of humans, which each theorist understood as taking different forms. For Marx it was alienation, for Weber confinement in the iron-cage of rationality, and for Durkheim anomie. Although Ibn Khaldun lived centuries before the rise of classical social theory and was by no means a product of the modern world, it is possible to read his work as thematising the absence of freedom or enslavement as well. Bringing out this aspect of Ibn Khaldun shows, to some extent, the modern relevance of his thought. This article elaborates on Ibn Khaldun's theme of enslavement via his discussion on luxury and senility. It is the enslavement of sedentary people to luxury that explains the loss of group feeling or ‘asabiyyah, setting in motion a chain of developments that results in the senility of the dynasty and its eventual demise. In the first section I discuss the Enlightenment promise of freedom. The section that follows discusses classical social theory's critique of modernity or what amounts to a loss of faith in the Enlightenment project. Here the thought of Marx, Weber and Durkheim are presented as examples of Western assessments of the problem of the human condition in modernity. I then turn in the next two sections to Ibn Khaldun, discussing his theory of the rise and decline of states in terms of the role played by luxury.     

Monitoring multivariate simple linear profiles using robust estimators

Brief Abstract

This article focuses on estimation of multivariate simple linear profiles. While outliers may hamper the expected performance of the ordinary regression estimators, this study resorts to robust estimators as the remedy of the estimation problem in presence of contaminated observations. More specifically, three robust estimators M, S and MM are employed. Extensive simulation runs show that in the absence of outliers or for small amount of contamination, the robust methods perform as well as the classical least square method, while for medium and large amounts of contamination the proposed estimators perform considerably better than classical method.     

‘It's just a natural human thing to do,to go and visit your family… but it's not easy for us’: Gender and generation in Bangladeshis’ transnational visits between London and Sylhet

In the title to this paper, Maya, a British-Bangladeshi woman, expresses her frustration at the refusal of the Home Office to grant her father in Sylhet a visa to come and fulfil his role as family head at the wedding of his son, Maya's brother, in London. The case illustrates well the intersection of gender and generation that fundamentally shapes the pattern of visits, in both directions, across this long-distance transnational social and family space. Bangladesh is a patriarchal society, with marked gender divisions layered across generations, which are largely reproduced among the migrant community in London and are manifested, in various ways, in the phenomenon of transnational visiting. Based on 61 in-depth interviews in London and Sylhet, supplemented by participant observation, we delineate the gendered and generational structures framing the visits, both of migrants to the homeland and of non-migrants to their relatives in London.     

A guide to the design and analysis of small clinical studies

Clinical studies, which have a small number of patients, are conducted by pharmaceutical companies and research institutions. Examples of constraints that lead to a small clinical study include a single investigative site with a highly specialized expertise or equipment, rare diseases, and limited time and budget. We consider the following topics, which we believe will be helpful for the investigator and statistician working together on the design and analysis of small clinical studies: definitions of various types of small studies (exploratory, pilot, proof of concept); bias and ways to mitigate the bias; commonly used study designs for randomized and nonrandomized studies, and some less commonly used designs; potential ethical issues associated with small underpowered clinical studies; sample size for small studies; statistical analysis methods for different types of variables and multiplicity issues. We conclude the paper with recommendations made by an Institute of Medicine committee, which was asked to assess the current methodologies and appropriate situations for conducting small clinical studies.     

Visiting migrants: An introduction

This paper offers an overview of the origins and dynamics of the concept of migrant visits and introduces the key contributions of the special issue. We highlight the significance of visits that criss-cross many forms of migration and centre on these visits’ bilateral and multilateral nature. Furthermore, we emphasize emotional, sensory and bodily implications, which almost always shape encounters between migrants and others in such visits. The papers of this special issue contribute to a broad interdisciplinary agenda highlighting familial ties, networks and transnational spaces at the core of migration and mobility scholarship. Together, we offer new perspectives on the multidirectionality of visits and the role of relationships which drive, connect and diversify forms of migration and are facilitated by broader developments in technology, tourism and diasporic practices.     

The limits of parametric reforms in sustaining the Algerian retirement system in a context of population ageing

Accelerated population ageing in Algeria threatens the financial sustainability of its pay-as-you-go retirement system. Reform is a necessity, with options ranging from simple parametric reforms to important systemic changes. Prior to undertaking systemic reforms, it is worthwhile to investigate whether parametric reforms can place the system on a financially sustainable footing. In this article, we used a multi-scenario analysis that crosses the possible reform actions with possible socioeconomic scenarios. The results show that when using the most favourable scenarios, the financial balance of the Algerian system will remain negative in the short and long term. Implementing major parametric reforms can only help reduce the deficit and make it stable over time. Thereafter, systemic reforms will have to be implemented.
