Strong consistency of conditional least squares estimators in multiple regime threshold autoregressive models

In this paper we analyse the conditional least squares estimators of the parameters of a multiple regime threshold AR(1) model and prove that under certain conditions these are strongly consistent. We assume that the error process in each regime is amartingale difference sequence. Then we deal with strong consistency of the natural estimator of the error variance in each regime.     

Sartre’s humanism and the Cuban revolution

Drawing its inspiration from the writings that Sartre dedicated to the Cuban revolution after his 1960 visit to the island, this article discusses his understanding of the relationship between socialism and freedom. The importance of these texts, which were never published in book form in France, goes beyond their specific analysis of the Cuban revolutionary process. They offer a good opportunity to deepen the study of themes central to Sartre’s thought and help us understand the complex connection that Sartre made between his criticism of colonialism and imperialism, and his vision of a socialist society that, by being centered on man and freedom, would not make the critical errors of so-called “real socialism.”     

The dynamics of child poverty in Sweden

This paper studies the dynamics of child poverty in Sweden. We find that one out of every five children is disposable income poor at least once during childhood, while only 2% are chronically poor. Children in Sweden are protected economically from many serious events such as parental sickness and death. Family dissolution and parental unemployment do push some children into poverty. However, these poverty spells are mostly temporary. Single mothers, for example, are overrepresented among the poor but not among the chronically poor. Children with immigrant parents are strongly overrepresented among the chronically poor.     

Work and Social Reproduction: Two Concepts for Interpreting the Post-Fordist Transition

This article discusses the definitions of the term “work” which could be applied to advanced industrial societies, and which cover an increasingly complex range of activities. The authors' definition can be viewed as an attempt to forge a significant link between economic and sociological analysis, in order to understand the complex connections, typical only of industrial societies, between different forms of work and employment, and the variety of patterns of social reproduction of diverse groups in different periods and contexts.     

From usability requirement to technical specifications for hand-held tools and materials: an applied research in the construction field

Literature shows incidence of musculoskeletal disorders in bricklaying workers as well as the relevance of good designed hand-held tools in musculoskeletal disorders prevention. In this framework, it can be supposed that providing usable hand-held tools and material in construction worksites will help to improve bricklayers' working conditions. Here a study is presented aimed at framing a methodology for usability assessment of bricklayers handled objects, in order to provide employers with practical indicators for choosing tools and materials best fitting workers needs, under the effectiveness, efficiency and satisfaction perspective. On the basis of a task analysis, usability requirements for bricklaying hand-held tools and materials have been detailed and related, quantitative and qualitative, technical specifications have been elicited. Theoretical framework and usability assessment methodology are presented and, finally, findings from a field application are discussed.

External audit and bankruptcy prediction

In this paper, we investigate the relationship between external auditor characteristics and the likelihood of bankruptcy. We use a sample of US public companies to analyse whether auditor attributes are associated with default. We also test whether the inclusion of such attributes in bankruptcy prediction models improves their predictive ability. We find that firms audited by industry-expert auditors, large audit firms and long-tenured auditors are less likely to default. Firms with higher audit fees are more likely to default. Our results also show that the inclusion of auditor attributes significantly increases the predictive ability of bankruptcy prediction models. This paper contributes to the literature about auditing and bankruptcy prediction. Our results suggest that the auditor attributes can provide predictive signals concerning a default risk and that an external audit can play a relevant role in early warnings of financial distress. Our study also suggests that bankruptcy prediction models can become more effective if they are complemented with audit data. Our results are of interest to market participants, auditors, regulating authorities, banks and other financial institutions that are interested in credit risk assessment.     

Remainers are nostalgic too: An exploration of attitudes towards the past and Brexit preferences

Nostalgia had a prominent place in the Brexit Referendum campaign, epitomized by Nigel Farage carrying around with him an old-fashioned blue British passport on the campaign trail. In this paper, we seek to examine British attitudes towards the past through a new survey instrument administered online in July and August 2018 (N = 3,000). We empirically establish two dimensions of nostalgia that are differentially associated with political preferences. We conclude that it is the substance of the nostalgia that matters, not the looking towards the past per se.     

Securitization of migration and the far right: the case of Greek security professionals

Since the events of 9/11, security concerns have gained unprecedented dominance on western governments' national and international political agendas; Greece has been no exception. The success or failure of a far right party, like Golden Dawn, depends on the effectiveness of the government to regulate immigration and to develop policies aimed at combating the racism which pervades the political culture of society at this particular juncture, when the country is experiencing severe crisis. The aim is to provide an account of the rationale of the securitization of migration from the perspective of Greek security professionals. We argue that the extreme securitizing perceptions of security professionals have been exploited and assisted by far‐right extremist groups, which instilled racial violence, hate speech/crime into society, resulting in patterned, unreflective, and routinized security practices and discourses which are more in line with the beliefs and values advocated by the extreme right.
