Bootstrap and Other Resampling Methodologies in Statistics of Extremes

In Statistics of Extremes, the estimation of parameters of extreme or even rare events is usually done under a semi-parametric framework. The estimators are based on the largest k-ordered statistics in the sample or on the excesses over a high level u. Although showing good asymptotic properties, most of those estimators present a strong dependence on k or u with high bias when the k increases or the level u decreases. The use of resampling methodologies has revealed to be promising in the reduction of the bias and in the choice of k or u. Different approaches for resampling need to be considered depending on whether we are in an independent or in a dependent setup. A great amount of investigation has been performed for the independent situation. The main objective of this article is to use bootstrap and jackknife methods in the context of dependence to obtain more stable estimators of a parameter that appears characterizing the degree of local dependence on extremes, the so-called extremal index. A simulation study illustrates the application of those methods.     

The Pacific Identity and Wellbeing Scale (PIWBS): A Culturally-Appropriate Self-Report Measure for Pacific Peoples in New Zealand

We describe and validate the Pacific Identity and Wellbeing Scale (PIWBS). The PIWBS is a culturally appropriate self-report measure assessing a five-factor model of Pacific identity and wellbeing. Items and construct definitions were developed through qualitative interviews, review of psychological theories, and previous research on Pacific concepts of ethnic identity and wellbeing. Exploratory and confirmatory factor analyses supported the model (Study 1 N = 143; Study 2 N = 443). The proposed five-factor model of Pacific identity and wellbeing includes scales assessing (1) Perceived Familial Wellbeing, (2) Perceived Societal Wellbeing, (3) Pacific Connectedness and Belonging, (4) Religious Centrality and Embeddedness, and (5) Group Membership Evaluation. The PIWBS provides a culturally appropriate valid and reliable assessment tool that can be used for within-cultural research for Pacific peoples from a Pacific perspective. A copy of the PIWBS and scoring instructions for its use are included.     

Social and Family Policies in Italy: Not Totally Frozen but Far from Structural Reforms

This article analyses the main shifts in the political and public discourse about families, children, elderly people, care needs and women‐friendly policies in Italy over the last two decades. It shows that while family and gender relationships have become an ideologically highly charged public issue, policies at the practical level have remained largely stagnant, marginal and fragmentary. At the same time, important institutional changes (such as the constitutional reform of 2001, which introduced a form of federalism) have created new problems of governance. The authors argue that in the face of inadequate policies, the recourse of individuals and families to old (family solidarity) and new (migrant labour) solutions may cause new tensions and inequalities.     

The Italian Case: From Employment Regulation to Welfare Reforms?

This article on the Italian case is based on recent trends in labour market reform. We critically review the reform approach adopted in recent years, mainly centred on marginal legislative reforms in employment contracts. The diffusion of flexible labour contracts, especially among the younger generations and women, together with a welfare system still based on employment seniority and job characteristics, have reinforced the segmentation of the Italian labour market and social inequalities. The absence of a negotiating strategy in introducing reforms has also increased social conflict. These trends ask for a comprehensive reform of the welfare system and for active policies to support labour market transitions, a reform which is increasingly considered in the current political debate.     

Ephemeral and Ludic Strategies of Remembering in the Streets: A Springboard for Public Memory in Chile

This article examines a profound turn in the commemoration and representations of the dictatorial past in Chile (1973–1990), where young people who did not experience firsthand the authoritarian order are publicly creating fleeting images, practices, and objects to remember the military dictatorship. These are urban ephemeral and ludic mnemonic assemblages (Freeman, Nienass, and Daniell 2015) that connect past and present events and demand new ways of talking, acting, and thinking about the past, thereby appropriating the public space. The participants in these actions stress the original, carnivalesque, and public dimensions of their practices, challenging the official politics of memory that has focused on the recognition of victims within the walls of museums or memorials. The following question guides this article: How do new public, ludic, and ephemeral strategies interact with and potentially change official ways of narrating the past? How do they create the space for political participation in postconflict societies? Drawing upon a qualitative and multimethod study that combines 60 in‐depth interviews, participant observations, and archival work, I maintain that, although this blossoming of the Chilean public memory has opened up new territories for activating memory, it has a transient temporality and, consequently, may have transitory political potential.     

Work ability among nursing personnel in public hospitals and health centers in Campinas--Brazil

Nursing personnel is essential in hospital, health centers and enterprises and is the large work force in health system. A cross-sectional study was conducted in a large city in two public hospitals and five health centre with the objective of to evaluate the work ability and health aspects of nursing staff. The sample was composed by 570 workers. The Work Ability Index - WAI and a questionnaire with socio-demographic, health and life style data was applied. The majority of workers was women (83%), married (50.4%), and was working in night shift work (65.6%); 61.4% was auxiliary nursing, 22.3% was registered nurses (RN). The average age was 38.9 years (SD 7.8) and the Body Mass Index mean was 25.8 (SD 5.3). Only 17.2% referred to practice at least 150 minutes of physical exercise five times per week or more. 26.8% had a second job. The work ability mean was 39.3 (SD 5.3) points. Age had a negative correlation with WAI (p=0.0052). Public hospital and health centre workers had poor work ability score when compared with workers from another branches. Public policies related to workplace health promotion need to be implemented in public hospital and health centre to improve the work ability.     

The Internetization of International Migration

The Internet has revolutionized our economies, societies, and everyday lives. Many social phenomena are no longer the same as they were in the pre‐Internet era: they have been “Internetized.” We define the Internetization of international migration, and we investigate it by exploring the links between the Internet and migration outcomes all along the migration path, from migration intentions to actual migration. Our analyses leverage a number of sources, both at the micro‐ and the macro‐level, including the Gallup World Poll, the Arab Barometer, data from the International Telecommunication Union, the Italian population register, and unique register data from a migrant reception center in Southern Italy. We also distinguish between economic migrants—those who leave their country of origin with the aim of seeking better economic opportunities elsewhere—and political migrants—those who are forced to leave their countries of origin for political or conflict‐related reasons. Our findings point to a consistently positive relationship between the diffusion of the Internet, migration intentions, and migration behaviors, supporting the idea that the Internet is not necessarily a driving force of migration per se, but rather an enabling “supportive agent.” These associations are particularly relevant for economic migrants, at least for migration intentions. Further analyses underscore the importance of the Internet in providing a key informational channel which helps to define clearer migration trajectories.
