Land,territory and commons: voices and visions from the struggles

ABSTRACT

All over the world, financial capitalism and extractivism are appropriating land as if it was nothing more than a commodity, a mere ‘factor’ of production that can be exploited to generate financial returns. Movements and activists are organizing, resisting, protecting and promoting life-giving visions against this continuous enclosure of living beings and paces: they use their bodies, laws, educational projects, histories and visions to regain control over territory as a political space, self-determine and create solidarities. In the act resistance, they are the target of moral, physical and legal violence. They and their ideas are criminalized, disciplined, punished and in some cases exterminated. In this contribution, activists from the Basque Country, Guatemala, Kenya and the Six Nations and a group of academics get together to learn from each other, support the ongoing search for common vocabularies and identify possible milestones of a coordinated and international strategy for a life-enhancing future.     

Designed for Patience: The Significance of Internal Factors in the Ukrainian and Belarusian Transitions

This paper focuses on Belarus in order to find explanation as to why Alexander Lukashenko was able remain the authoritarian leader of Belarus, while in Ukraine the position of the political elite had proved less stable and collapsed in 2004. We seek to determine whether the internal factors (macroeconomic conditions, standard of living, the oppressive nature of the political system) play a significant role in the operation of the domino effect. This article emphasises the determining role of immanent internal factors, thus the political stability in Belarus can be explained by the role of the suppressing political regime, the hindrance of democratic rights and the relatively good living conditions that followed the transformational recession. Whilst in Ukraine, the markedly different circumstances brought forth the success of the Orange Revolution.      

On the manipulation of social choice correspondences

Duggan and Schwartz (Soc Choice and Welfare 17: 85–93, 2000) have proposed a generalization of the Gibbard–Satterthwaite Theorem to multivalued social choice rules. They show that only dictatorial rules are strategy-proof and satisfy citizens sovereignty and residual resoluteness. Citizens sovereignty requires that each alternative is chosen at some preference profile. Residual resoluteness compels the election to be single-valued when the preferences of the voters are “similar”. We propose an alternative proof to the Duggan and Schwartz’s Theorem. Our proof highlights the crucial role of residual resoluteness. In addition, we prove that every strategy-proof and onto social choice correspondence concentrates the social decision power in the hands of an arbitrary group of voters. Finally, we show that this result still holds in a more general framework in which voters report their preferences over sets of alternatives.     

Urban poverty and labor market dynamics in five Latin American countries: 2003–2008

Latin America experienced a long period of sustained growth since 2003 that positively impacted social and labor market indicators, including poverty. This paper contributes to the understanding of this process as it carries out a comparative study of poverty dynamics in five Latin American countries during 2003–2008. It analyzes the extent to which countries with different levels of poverty incidence diverge in terms of poverty exit and entry rates, identifies the relative importance of the frequency and impact of events associated to poverty transitions and examines how these events affect households with different characteristics. For this, a dynamic analysis of panel data is carried out using regular household surveys. Sizeable rates of poverty movements were observed in all five countries and it was found that a large proportion of household experienced positive events, mainly related to the labor market; however, only a small fraction of them actually exited poverty. Demographic events and public cash transfers proved to be of little relevance; in particular, the latter did not contribute much either to intensify poverty exits or to prevent poverty entries. Households with children experienced more (less) negative (positive) events than those without children. It appeared therefore that even when the economy behaved reasonably well at the aggregate level, high levels of labor turnover and income mobility (even of a negative nature) still prevail, mainly associated to the high level of precariousness and the undeveloped system of social protection that characterize the studied countries.     

The relational costs of crossing class lines

How do low socioeconomic status students navigate cross-class interactions in extremely unequal contexts? Previous research has described the high costs of college integration for underprivileged students, which in turn, negatively impact academic performance and general wellbeing. These studies tend to concentrate on cultural capital costs, such as catching up with assumed middle-class or elite capital and dealing with two worlds. Less has been said about social capital costs, the costs of making friends, especially more privileged friends. Through 61 in-depth interviews with various types of students as part of a broader ethnographic fieldwork, this article analyses the experiences of low-income scholarship holders in an elite institution in a very unequal society, Colombia. Rather than isolating themselves or resorting to safe homophilic relations, they faced their new elite environment engaging with the hidden relational cost of making friends with more affluent students. In so doing, they had to overcome fears and experiences of discrimination and micro-aggressions, as well as cultural and economic capital barriers, and employed either camouflaging or disclosure strategies, sometimes becoming culturally and socially omnivorous. Symbolic belonging to the institution and the acquisition of middle-class cultural capital were among the benefits that made overcoming the costs worthy. Our results shed light on what institutions can do to reduce the costs for underprivileged students and, theoretically, unveil an important mechanism and barrier for social mobility: building cross-class ties.

Interrupted aspirations: research and policy on Gitano education in a time of recession,in Spain

During the past decade, Gitano students’ school success and its cultural, social and emotional consequences have been largely unexplored, particularly in a new context: the deep economic crisis in Spain. This study reviews and analyses the evolution of the research production and the changing contexts of policy trends affecting the ‘Roma education issue’ as they have developed in Spain during the past decade (2004–2014). The authors take as a starting point the groundbreaking study published in 2004 that focused on trajectories of educational achievement and continuity among Gitano youth, and go on to reconstruct the approaches undertaken by qualitative, quantitative and evaluation research since then, in relation to their contributions to improve policy recommendations. The role played by Spanish and European social and educational strategies addressed to the Gitano/Roma population is critically explored to challenge the controversial notion of a ‘Spanish model of Roma integration’. Finally, the authors argue that the deterioration of public education and the virtual disappearance of social benefits in recent years, in addition to the worrying actions taken against Roma citizens in the EU, are to account for the interrupted aspirations of a whole generation of Gitano/Roma youth.     

Optimum design-based ratio estimators of the distribution function

The ratio method is commonly used to the estimation of means and totals. This method was extended to the problem of estimating the distribution function. An alternative ratio estimator of the distribution function is defined. A result that compares the variances of the aforementioned ratio estimators is used to define optimum design-based ratio estimators of the distribution function. Different empirical results indicate that the optimum ratio estimators can be more efficient than alternative ratio estimators. In addition, we show by simulations that alternative ratio estimators can have large biases, whereas biases of the optimum ratio estimators are negligible in this situation.     

Optimal Method for Realizing Two-Sided Inferences About a Linear Combination of Two Proportions

In order to reach the inference about a linear combination of two independent binomial proportions, various procedures exist (Wald's classic method, the exact, approximate, or maximized score methods, and the Newcombe-Zou method). This article defines and evaluates 25 different methods of inference, and selects the ones with the best behavior. In general terms, the optimal method is the classic Wald method applied to the data to which z ² _α/2/4 successes and z ² _α/2/4 failures are added (≈1 if α = 5%) if no sample proportion has a value of 0 or 1 (otherwise the added increase may be different).

Why is not design of experiments widely used by engineers in Europe?

An extensive literature review was carried out to detect why design of experiments (DoE) is not widely used among engineers in Europe. Once 16 main barriers were identified, a survey was carried out to obtain first-hand information about the significance of each. We obtained 101 responses from academics, consultants and practitioners interested in DoE. A statistical analysis of the survey is introduced, including: (a) a ranking of the barriers, (b) grouping of barriers using factorial analysis, (c) differences between characteristics of respondents. This exploratory analysis showed that the main barriers that hinder the widespread use of DoE are low managerial commitment and engineers’ general weakness in statistics. Once the barriers were classified, the most important resultant group was that related to business barriers.
