The regulation of work activity and the new labor and production contexts

In recent decades, there has been a rise in the use o lean production model techniques. Through this approach, companies become more flexible, a fact that increases the interest in studies regarding the introduction of this model in businesses and its impacts on working conditions. Important observations concerning ergonomics, such as the theme of work activity regulation, have been highlighted in such studies. This article aims to discuss strategies and regulations adopted by the workers on assembly lines that are considered flexible. The article presents the results of a study in a company that adopts some lean production techniques. The study was analyzed using the activity analysis as one of the premises of the Ergonomic Work Analysis (EWA). Many aspects of the traditional assembly line remain present in the scenario that was studied, however a new language was employed and aspects in the nature of regulations demonstrate that the relation with lean production techniques influence the operators' operational modes.     

Accessibility of sports facilities for persons with reduced mobility and assessment of their motivation for practice

This study aims to create awareness, both within the scientific community and among providers of sports facilities, for individuals with impaired or reduced mobility, promoting the development of technical solutions that allow greater autonomy and social integration of people with disabilities. The purpose of this work is, on the one hand, to evaluate the accessibility of sports facilities for people with reduced mobility and, on the other hand, to investigate why this user group has such low rates of participation in sporting activities. Firstly, using the Portuguese norms and legislation transcribed from European Community directives, a check list was created comprising all the items that sports facilities should abide by in order to provide accessibility and safety to people with reduced mobility. Another questionnaire was designed aimed at this user group, with questions pertaining to their desire and ability to use sports facilities. This questionnaire was distributed in Portugal, in the greater metropolitan area of Porto, to users of Rehabilitation Centres and Physiotherapy Clinics. The results obtained from the check-list showed the compliances and non-compliances of the respective sports facilities, proving that many barriers preventing the participation of people with reduced mobility still exist. Twenty-four people with permanent impairment of the lower extremities (paraplegia) answered the questionnaire pertaining to the desire and ability to perform physical activity. Two individuals (8%) had sporting activities available to them in their area of residence and only five (21%) performed any physical activity. The main reason given for not taking part in any activity was the lack of adapted sports facilities. All the participants felt that taking part in sports is beneficial. The benefits stated were: general well-being and development of the psychomotor component (e.g. coordination, balance, body posture), of physical condition (e.g. strength, resistance, flexibility) and social integration and quality of life. Besides wellbeing, they also mentioned social interaction, a way of occupying their time and an escape from the routine as the main motives for which they would like to take up physical exercise.     

Delegating home care for the elderly to external caregivers? An empirical study on Italian data

We study care arrangement decisions in Italy, where families are increasingly delegating the role of primary caregiver to external (paid) people also for the provision of home care. We consider a sample of households with a dependent elderly person cared for either at home or in a residential home, extracted from a survey representative of the population of Italy’s Emilia-Romagna region. We investigate the determinants of a household’s decision to opt for one of the following three alternatives: the institutionalisation of elderly family members, informal home care, or paid home care. We estimate two model specifications, based on a simultaneous and a sequential decision process respectively, the results of which are fairly consistent. Disability related variables, rather than family characteristics, emerge as the main determinants of institutionalisation. On the other hand, household characteristics and socio-economic variables are more influential when it comes to choosing between informal and formal home care provisions.     

Social epigenetics: a science of social science?

Epigenetics has considerable potential to transform social science by embedding mutually regulative reciprocal connections between biological and social processes within the human activities it studies. This paper highlights common epigenetic methods and outlines practical considerations in the design of ‘social epigenetics’ research addressing the identification of biomolecular pathways, statistical inference of causality, conceptualization of the environment as a biochemical event, heritability of epigenetic alterations and intergenerational accountability, and concept of time implied by attempts to capture complex, non-linear gene-environment interactions. Finally, we reflect on the social epigenome as a conceptual space and try to identify barriers to translation, and practical and ethical issues raised by epigenetics research. In order for social epigenetics and social science to contribute to the emergence of this putative ‘science of social science’ and to capture meaningful human experience they will both need to change significantly.     

The impact of delayed maternity on foetal growth in Spain: An assessment by population attributable fraction

Background

Delayed childbearing is considered a risk factor for maternal–foetal health. As in other higher-income countries, in Spain age at maternity has steadily increased during the last two decades.

Modelling of socio-ecological connectivity. The rural-urban network in the surroundings of Madrid (Central Spain)

As most of Europe’s metropolitan landscapes grow, a change is occurring in their surrounding rural environment. The consequences thereof mainly involve losses of traditional land uses and changes in the socioecomic structures of the local population. The lack of coupling ‘urban society-countryside’ can be considered to constitute a driving force of this process. The present paper focuses upon the rural-urban network around the metropolis of Madrid (Central Spain). We developed a quantitative model to explain the socio-ecological rural-urban linkages, taking into account the influence of the metropolis in the network of neighbouring municipalities. The results show a rural landscape gradient ranging from silvo-pastoral to agricultural land uses and maintaining different interactions with the local socioeconomy. Urban-rural polarisation of the territory and accessibility to the metropolis are the main factors influencing the landscape dynamics. Territorial cohesion among municipalities and connectivity with the metropolis are factors determining the socio-ecological structure. The agricultural area presents good social cohesion, but a weak connection with the City. The silvo-pastoral landscape, on the contrary, maintains prominent links with the metropolis, but a non-significant interconnection between the small towns. The model tested constitutes a useful tool for analysing socio-ecological connectivity and for quantifying, designing and promoting territorial cohesion policies.     

Antiblackness as a Logic for Anti-Immigrant Resentment: Evidence From California

Drawing on data from a novel survey of Californians, this article examines the relationship between anti-immigrant resentment and antiblackness. Over the last decade, there has been a significant increase in research on anti-immigrant resentment, as well as a steady growth in public opinion literature on antiblack bias. Nonetheless, there are almost no studies that examine the relationship between these types of attitudes. Using two different measures of anti-immigrant resentment and three different measures of antiblack bias, we find that antiblackness among those Californians surveyed was significantly and robustly correlated with anti-immigrant resentment. Our findings suggest that even in a state where there is a relatively small black population and where there is little overlap between the categories of “black” and “immigrant,” attitudes toward blacks may be shaping attitudes toward immigrants. The findings suggest a need to move beyond dyadic theories of othering and in doing so, to think more critically about how the racialization of one group can shape the racialization of other groups.     

Fractured lives: understanding urban youth vulnerability in Perú

ABSTRACT

The paper reports on a mixed methods study that sought to analyse determinants of youth labour market and educational disengagement in Peru. It begins by questioning the widespread focus on NEET – youth not in employment, education or training – as a measure of youth vulnerability in countries with extensive informal labour markets where labour precarity can be as problematic as unemployment for young people’s futures. A broader category of ‘urban vulnerable’ youth, including both NEET and precarious workers, is proposed and used as the basis for analysing the factors that influence young people’s trajectories. Key factors and shocks in youth trajectories are identified through qualitative life histories, and are tested using cross-section and panel survey data. Findings from the study have implications for the analysis of youth labour market vulnerability in the Global South, as well as for the policies that seek to address this problem.     

The Loss of Efficiency Estimating Linear Functions under Restrictions

This article is motivated by the problem of estimating contrast in a one-way ANOVA model with restrictions in the parameter vector. We prove that when the restrictions are given by a tree order or a simple order the MLE of some contrast has greater MSE than the unrestricted estimator. A similar behaviour of the MLE is exhibited in a general restricted setting given by a multivariate normal distribution with mean vector constrained to belong to a circular cone. The approach we use focuses on the central direction of the cones. These directions appear to have the greater MSE when the dimension of the restricted cone is big enough.     

Tools for evaluating EU agricultural policies: An integrated approach

The aim of this paper is to propose a theoretical “multi-phase” strategy for analysing in dynamic terms the territorial impact of agricultural and environmental EU policy measures. This approach should also allow to evaluate the adjustment capability of farms as a function of the characteristics of different territories. The proposed methodology is illustrated by an example using data relative to the 41 provinces of Northern Italy. In the first step, a multivariate statistical analysis (MSA) consisting in Principal Component Analysis and Cluster Analysis leads to the identification of homogeneous clusters of territorial units. The territorial mapping is conditional to a predetermined set of indicators that takes into account different aspects of agricultural development. In a second step, Positive Mathematical Programming (PMP) allows to introduce the impact of agricultural policies (compensatory payments, price changes, etc.) returning different scenarios of land use and agricultural profitability. According to the outputs of the PMP, the third step consists in a new MSA for detecting any changes in the territorial mapping. Convergence analysis can then synthesise the impact of the different policy options.
