Measuring Human Development: A Multi-criteria Approach

In 2010 the Human Development Index (HDI) was revised with several major changes. Many of its problems were tackled, although some drawbacks still persist. This paper proposes a multi-criteria approach to measure human development, propounding two innovations for the computation of the HDI: (1) the introduction of a double reference point scheme in the normalization; (2) an aggregation function which deals with the problem of substitutability between components. In particular, for each component of the HDI the value of each country is normalized by means of two reference values (aspiration and reservation values) by using an achievement scalarizing function that is piecewise linear. Aggregating the new normalized values, we calculate a range of indices with different degrees of substitutability: (1) a weak index that allows total substitutability; (2) a strong index that measures the state of the worst component and allows no substitutability; and (3) a mixed index that is a combination of the first two.     

Sustainability Ranking for Cuban Tourist Destinations Based on Composite Indexes

This investigation approaches the levels and the predictors of loneliness among migrant youths from returned migrant families from France to Portugal. Three research questions guided the study: (1) Does loneliness of migrant youths differ from those who have never migrated? (2) Are migrant youths’ re-acculturation factors related to their loneliness? (3) Is the adaptation of migrant youths linked to their loneliness? The answer to these questions is important to improve migrant youths’ re-acculturation experiences and their adaptation. The sample included 222 youths from returned migrant families from France. Participants completed the brief Portuguese version of the Revised UCLA Loneliness Scale (ULS-6), in addition to measures of re-acculturation and adaptation. A control group comprised of 211 Portuguese adolescents who have never migrated was also involved in the investigation. Youths from returned migrant families showed lower levels of loneliness than their native Portuguese counterparts who have never migrated. Demographic, re-acculturation, and adaptation factors were significantly related to adolescents’ loneliness. Major predictors of loneliness were age at return, contacts with peers without migratory experience, perceived discrimination, stressful adaptation experience, and satisfaction with life.     

Linking Social Support to Psychological Distress in the Unemployed: The Moderating Role of Core Self-Evaluations

In this study, an integrative analysis involving social support and core self-evaluations (CSE) as concurrent predictors of psychological distress among unemployed adults was conducted. The main aim of this study was to evaluate the relationship between perceptions of social support and CSE with psychological distress among unemployed adults, as well as whether levels of CSE moderated the relations between social support and psychological distress. Results indicated that, along with the expected direct and additional influence, a significant social support × CSE interaction was found in explaining several dimensions of psychological distress beyond the independent effect of socio-demographic variables, social support and CSE independently. Specifically, we found significant interaction for social support × CSE in explaining stress and anxiety symptoms. Our data provide empirical support for theoretical and conceptual work connecting social support, CSE and psychological distress associated with unemployment suggesting that alone, but also in combination, these contextual and personal resources may be particularly relevant for leading to reduced psychological distress during unemployment. Finally, theoretical implications of the joint study of these constructs and their relation with psychological distress in unemployed people are discussed.     

A new class of survival regression models with heavy-tailed errors: robustness and diagnostics

Birnbaum-Saunders models have largely been applied in material fatigue studies and reliability analyses to relate the total time until failure with some type of cumulative damage. In many problems related to the medical field, such as chronic cardiac diseases and different types of cancer, a cumulative damage caused by several risk factors might cause some degradation that leads to a fatigue process. In these cases, BS models can be suitable for describing the propagation lifetime. However, since the cumulative damage is assumed to be normally distributed in the BS distribution, the parameter estimates from this model can be sensitive to outlying observations. In order to attenuate this influence, we present in this paper BS models, in which a Student-t distribution is assumed to explain the cumulative damage. In particular, we show that the maximum likelihood estimates of the Student-t log-BS models attribute smaller weights to outlying observations, which produce robust parameter estimates. Also, some inferential results are presented. In addition, based on local influence and deviance component and martingale-type residuals, a diagnostics analysis is derived. Finally, a motivating example from the medical field is analyzed using log-BS regression models. Since the parameter estimates appear to be very sensitive to outlying and influential observations, the Student-t log-BS regression model should attenuate such influences. The model checking methodologies developed in this paper are used to compare the fitted models.     

Rural and Urban Differences in Economic Experiences,Anxiety and Support for the Post-communist Reforms in the Czech and Slovak Republics1

Abstract The economic experiences and economic anxiety of rural and urban residents of the Czech and Slovak Republics during the postcommunist reforms are compared and related to their support for the reforms. The analysis is based on five national surveys, 1992–1996, collected by the Sociology Institute of the now Czech Academy of Sciences. Net of controls, both Czech and Slovak rural respondents report more economic strain and unemployment, a difference that persists over the surveys. These experiences account for rural residents' greater economic anxiety, their fear of economic development and unemployment, which also persists over the surveys. These experiences and anxiety explain, in turn, their lower level of support for the reforms, and endorsement of a return to socialism and strong-hand government. Rural and urban respondents of the two countries have experienced the world differently since 1990, and this is expressed in their economic anxiety and political preferences.     

Inclusive design in the implementation of projects for schools modernization in Portugal - case studies

The Project for Schools Modernization taking place in Portugal, with an estimated total investment of 2450 million for the intervention in the first 205 schools, provide the reclassification of 332 secondary schools by 2015. One of the questions we can pose is if the authorities and the teams of architects selected to design these schools considered fundamental for the correctness of architectural barriers within the school and its accessibility the implementation of standards and principles of inclusion of children/teenagers with special needs within their school environment. As most of the projects are already being implemented, the main aim of this paper is to present the outcomes of a comparative analysis and synthesis of six schools located in the northern part of the country. This analysis occurs from the of Participatory Design perspective which appeals to the experience of the disable children to look (or evaluate) the negative and positive factors in terms of physical space, interpreted by inclusive design rules and orientations. Therefore, the evaluation of schools modernization project, and its discussion, is central for the understanding how these children are addressed in projects which are directed at them.     

Methodological proposal for occupational health and safety actions in research laboratories with nanotechnologies activities

Nanotechnologies is a multidisciplinary set of techniques to manipulate matter on nanoscale level, more precisely particles below 100 nm whose characteristic due to small size is essentially different from those found in macro form materials. Regarding to these new properties of the materials there are knowledge gaps about the effects of these particles on human organism and the environment. Although it still being considered emerging technology it is growing increasingly fast as well as the number of products using nanotechnologies in some production level and so the number of researchers involved with the subject. Given this scenario and based on literature related, a comprehensive methodology for health and safety at work for researching laboratories with activities in nanotechnologies was developed, based on ILO structure guidelines for safety and health at work system on which a number of nanospecific recommendations were added to. The work intends to offer food for thought on controlling risks associated to nanotechnologies.     

Structuring software anthropometric variables on CD Rom as a facilitator of the process of design of work situations

The environment where everyday activities are developed, these should be appropriate and the individual who will execute them, for greater efficiency of their work and even if you feel safe, comfortable and satisfied when interacting with that space, expending less energy to this interaction. Given this context, this study aims to structure a software with the results obtained in the field, from anthropometric measure to subsidize the furniture industry in manufacturing of furniture, definition work situations, considering the different anthropometric measurements made between 2001 and 2010, using data from this sample of adults aged 18 to 65 years old and children between 6 and 11 years old. It was convenient to make the software with a site, only instead of staying on the Web has been recorded on CD Rom. Tests with the prototype allow navigation through the structure of the software. The data needed to implement the remaining modules were also raised. Issues related to system layout and usability of the interface also were not considered, because it is an initial prototype.     

Ergonomic and usability analysis on a sample of automobile dashboards

This is a research study based on an analysis which sets out to identify and pinpoint ergonomic and usability problems found in a sample of automobile dashboards. The sample consisted of three dashboards, of three different makes and characterized as being a popular model, an average model and a luxury model. The examination was conducted by observation, with the aid of photography, notes and open interview, questionnaires and performing tasks with users, the bases of which are on the principles laid down by methodologies. From this it was possible to point to the existence of problems such as: complaints about the layout, lighting, colors, available area, difficult access to points of interaction, such as buttons, and the difficult nomenclature of dials. Later, the findings and recommendations presented show the need for a further, deeper study, using more accurate tools, a larger sample of users, and an anthropometric study focused on the dashboard, since reading and understanding it have to be done quickly and accurately, and that more attention be given to the study of automobile dashboards, particularly in the most popular vehicles in order to maintain the standards of usability, and drivers' comfort and safety.
