Geospatial Modeling of Containment Probability for Escaped Wildfires in a Mediterranean Region

Despite escalating expenditures in firefighting, extreme fire events continue to pose a major threat to ecosystem services and human communities in Mediterranean areas. Developing a safe and effective fire response is paramount to efficiently restrict fire spread, reduce negative effects to natural values, prevent residential housing losses, and avoid causalties. Though current fire policies in most countries demand full suppression, few studies have attempted to identify the strategic locations where firefighting efforts would likely contain catastrophic fire events. The success in containing those fires that escape initial attack is determined by diverse structural factors such as ground accessibility, airborne support, barriers to surface fire spread, and vegetation impedance. In this study, we predicted the success in fire containment across Catalonia (northeastern Spain) using a model generated with random forest from detailed geospatial data and a set of 73 fire perimeters for the period 2008–2016. The model attained a high predictive performance (AUC = 0.88), and the results were provided at fine resolution (25 m) for the entire study area (32,108 km²). The highest success rates were found in agricultural plains along the nonburnable barriers such as major road corridors and largest rivers. Low levels of containment likelihood were predicted for dense forest lands and steep-relief mountainous areas. The results can assist in suppression resource pre-positioning and extended attack decision making, but also in strategic fuels management oriented at creating defensive locations and fragmenting the landscape in operational firefighting areas. Our modeling workflow and methods may serve as a baseline to generate locally adapted models in fire-prone areas elsewhere.     

Graphical comparison of normality tests for unimodal distribution data

A methodology is proposed to compare the power of normality tests with a wide variety of alternative unimodal distributions. It is based on the representation of a distribution mosaic in which kurtosis varies vertically and skewness horizontally. The mosaic includes distributions such as exponential, Laplace or uniform, with normal occupying the centre. Simulation is used to determine the probability of a sample from each distribution in the mosaic being accepted as normal. We demonstrate our proposal by applying it to the analysis and comparison of some of the most well-known tests.     

From Sacred Place to Monumental Space: Mobility Along the Way to St. James

Human intervention and social practices have been pivotal for the creation of sacred spaces; indeed, the mobility of human beings has endowed spaces with meaning through religious cultural products. Progressive human intervention in holy places has turned them into monumental spaces, where cultural heritage has become a symbol of identity and the space has assumed the values of the culture that produced it. In this paper, we investigate the value of heritage along pilgrimage routes, as in the case of the Way of St. James. The sacred-monumental space works according to the system of artistic and cultural elements that define it as an integrated system. We will focus on the twentieth-century rediscovery of the Way in Spain, on the processes of monumental reinterpretation that culminated in its declaration, in 1987, as ‘First European Cultural Route’ by the Council of Europe, and as ‘UNESCO World Heritage Site’, in 1993.

Social and academic profile of the university student of social work a comparative study in Spain,Argentina, and Venezuela

ABSTRACT

The article presents the results of an empirical investigation that aimed to analyze comparative socio-demographic characteristics, motivational aspects and professional role of students who attend universities. The contexts of research were University of Mar de Plata (Argentina), University of Murcia (Spain) and University of Zulia (Venezuela). The universe of research was 304 students, with the participation of a total of 253 (TR 83,2%), 109 from University of Murcia—Spain—100 from University of Mar del Plata—Argentina and 44 from University of Zulia—Venezuela. Two hundred and forty-four measuring instruments were checked favorably. The results of the research allowed to highlight significant coincidences in most of the variables studied. In the analysis of self-perceived personality styles, there is high coincidence both in style (attributed qualification) and score (assigned quantification). At the three universities, the docent–student relationship is a positive variable that affects the favorable self-perception beyond academic success. Design and implementation of programs based on the described characteristics are recommended.     

The Prison and the Border: An Ethnography of Shifting Border Security Logics

This study examines the ways in which border controls have taken on aspects of crime control. To understand this transformation, I draw on the methods of historical anthropologists who blend ethnographic and historical tools of analysis. The historical research shows that the shift occurred in 1990s, when New Democrats adopted crime politics of the New Right and supported bipartisan policies that restructured detention, deportation, and criminal prosecution. The ethnography documents the ways in which border controls have taken on aspects of internal security and domestic policing, shifts seldom captured in contemporary border security debates.     

Professional competencies in social work education for the third sector in southern Spain

The education of social workers in the Spanish university is structured around the professional competencies that will subsequently be applied in the labour market. As social work is a profession focused on the provision of social welfare and the prevention of social exclusion, it is expected of social workers that they become analytical, thoughtful professionals within their environment and that they play an active role in preventing social exclusion and inequality. However, there are important splits and contradictions between the official recognition of such competencies by universities and their effective implementation in the labour market. In this paper we analyse the main constraints and contradictions involved in the acquisition of the professional skills of social workers in their transition to the labour market. To do this, we focus on the specific case competencies in professional field of the third sector in Andalusia

Maternal and Paternal Mental‐state Talk and Executive Function in Preschool Children

The present study examined the relationship between parents’ mental‐state talk and preschoolers’ executive function. Seventy‐two children participated in the present study, as well as their mothers and fathers. When children were enrolled in the second preschool year, mothers’ and fathers’ use of mental‐state references were assessed during a shared picture‐book reading task with the child. Later, four months before admission to the first grade, preschoolers’ executive function was measured. Hierarchical regression analysis revealed that maternal, but not paternal, mental‐state talk was a significant predictor of children's executive function composite, even after accounting for child gender, age, verbal ability, and parental education. When looking at each of the EF components, maternal mental‐state talk proved to be a predictor of set‐shifting whereas no significant relations emerged with inhibitory control or working memory. These findings add to prior research on parenting quality and executive function in preschoolers.     

The Lamé class of Lorenz curves

In this paper, the class of Lamé Lorenz curves is studied. This family has the advantage of modeling inequality with a single parameter. The family has a double motivation: it can be obtained from an economic model and from simple transformations of classical Lorenz curves. The underlying cumulative distribution functions have a simple closed form, and correspond to the Singh–Maddala and Dagum distributions, which are well known in the economic literature. The Lorenz order is studied and several inequality and polarization measures are obtained, including Gini, Donaldson–Weymark–Kakwani, Pietra, and Wolfson indices. Some extensions of the Lamé family are obtained. Fitting and estimation methods under two different data configurations are proposed. Empirical applications with real data are given. Finally, some relationships with other curves are included.
