Bayesian analysis of fingerprint, face and signature evidences with automatic biometric systems

The Bayesian approach provides a unified and logical framework for the analysis of evidence and to provide results in the form of likelihood ratios (LR) from the forensic laboratory to court. In this contribution we want to clarify how the biometric scientist or laboratory can adapt their conventional biometric systems or technologies to work according to this Bayesian approach. Forensic systems providing their results in the form of LR will be assessed through Tippett plots, which give a clear representation of the LR-based performance both for targets (the suspect is the author/source of the test pattern) and non-targets. However, the computation procedures of the LR values, especially with biometric evidences, are still an open issue. Reliable estimation techniques showing good generalization properties for the estimation of the between- and within-source variabilities of the test pattern are required, as variance restriction techniques in the within-source density estimation to stand for the variability of the source with the course of time. Fingerprint, face and on-line signature recognition systems will be adapted to work according to this Bayesian approach showing both the likelihood ratios range in each application and the adequacy of these biometric techniques to the daily forensic work.     

Losers' Second Chances and Control of the Party Machine: Aspirant Premiers in Regional Spain

In parliamentary democracies, controlling party machines has traditionally been a key asset for nascent political leaders, allowing them to continue in their position even after suffering a bad electoral start. Recent research suggests that in ‘old democracies’ this is no longer the case. Seeking to find whether this finding also applies to ‘young democracies’, the article analyses a dataset (built by the author) of candidates from the main national parties for the premiership of the Spanish Comunidades Autónomas, to ask whether being party chair increases the chances of ‘reselection’ after losing a first election. I conclude that in Spain, an example of a ‘young’ democracy, party machines still play a fundamental role at the start of politicians' leadership careers.     

Materials and devices of the public: an introduction

Abstract

This introduction provides an overview of material- or device-centred approaches to the study of public participation, and articulates the theoretical contributions of the four papers that make up this special section. Set against the background of post-Foucauldian perspectives on the material dimensions of citizenship and engagement – perspectives that treat matter as a tacit, constituting force in the organization of collectives and are predominantly concerned with the fabrication of political subjects – we outline an approach that considers material engagement as a distinct mode of performing the public. The question, then, is how objects, devices, settings and materials acquire explicit political capacities, and how they serve to enact material participation as a specific public form. We discuss the connections between social studies of material participation and political theory, and define the contours of an empiricist approach to material publics, one that takes as its central cue that the values and criteria particular to these publics emerge as part of the process of their organization. Finally, we discuss four themes that connect the papers in this special section, namely their focus on (1) mundane technologies, (2) experimental devices and settings for material participation, (3) the dynamic of effort and comfort, and (4) the modes of containment and proliferation that characterize material publics.     

Back to the Suitcase? Emigration during the Great Recession in Spain

The complex and multidimensional economic crisis experienced by Spain since 2008 significantly altered migration patterns in this country. Large scale unemployment contributed to slow down migrant inflows and accelerated out-migration flows in Spain. The media coverage of these processes created a distorted image of the patterns of migration affecting Spain during the crisis. Although the incipient economic recovery has not had a major impact in terms of modifying the migration dynamics triggered by the crisis, the media attention to this issue has substantially decreased without questioning its previous approach to the phenomenon. This article presents extensive data from a wide range of sources covering the period 2008–2016 to extract detailed information about the reality of crisis-era migration flows in Spain, and discusses the extent to which the media treatment of the issue has contributed to a partial and misleading view of the causes and consequences of the new Spanish emigration.     

The strange case of a national anthem without lyrics: music and political identities in Spain (1785–1913)*

Over the course of the long nineteenth century, between 1785 and 1913, Spain underwent processes of national construction similar to those experienced in other European countries. This phenomenon can be analysed through the crucial aspect of national symbols. Music played a leading role in these processes and engendered two opposing models, the product of internal political divisions. One, influenced by the style of the French Revolution, gave rise to a great many popular songs and was represented most of all by the Himno de Riego or “Riego Hymn,” the preferred anthem of the liberal and democratic left. The other, following a monarchist template inspired by the United Kingdom, was embodied in the Marcha Real or Royal March, a piece of ceremonial music without words that was promoted by conservative sectors opposed to popular political mobilization. The struggle between the two resulted in the adoption of the latter march as Spain’s official national anthem, although its association with the monarchy and the Catholic religion impeded the formation of a broad consensus around it. Contrary to the arguments maintained by many historians until a few years ago, the case of Spain cannot be considered as exceptional, although it did have certain peculiarities deriving from conflicts between different versions of Spanish nationalism and between the nationalism of the state and the sub-state nationalist movements that emerged towards the end of this period.     

Fat embolism syndrome associated with atraumatic compartment syndrome of the bilateral upper extremities: An unreported etiology

Fat embolism syndrome (FES) is a potentially life-threatening condition that develops when fat embolism leads to clinical symptoms and multisystem dysfunction. The classic triad of respiratory distress, neurologic symptoms, and petechial rash are non-specific, and the lack of specific laboratory tests makes the diagnosis of FES difficult. Although FES is most common after long bone fractures, multiple conditions some of which are atraumatic have been associated with the development of FES. We report a case of FES that occurred in the setting of a non-traumatic compartment syndrome of the upper extremities. The pathologic and clinical findings, pathophysiology, diagnostic challenges, and pathologic methods to properly diagnose FES are discussed with a review of the relevant literature. This case highlights the importance of the autopsy in making a diagnosis of FES in cases where death could otherwise be incorrectly attributed to multi-organ system failure, shock, or sepsis.     

Patients of the state: an ethnographic account of poor people's waiting

Drawing on six months of ethnographic fieldwork in the main welfare office of the city of Buenos Aires, this article dissects poor people's lived experiences of waiting. The article examines the welfare office as a site of intense sociability amidst pervasive uncertainty. Poor people's waiting experiences persuade the destitute of the need to be patient, thus conveying the implicit state request to be compliant clients. An analysis of the sociocultural dynamics of waiting helps us understand how (and why) welfare clients become not citizens but patients of the state.
