Using Twitter for Dialogic Communication: Local Government Strategies in the European Union

Abstract

Social networks have changed the way in which governments communicate with citizens, encouraging them to participate in decision-making processes. Nevertheless, few studies have specifically addressed the use of social networks in public sector from the standpoint of dialogic communication theory. The aim of this study is, first, to analyse the extent to which European local governments are developing dialogic strategies in their Twitter profiles in order to establish and enhance relations with their citizens and then to examine the impact of certain factors on the implementation of these dialogic strategies. The findings show that the situation is open to improvement, because local governments are mostly unaware of the benefits offered by the use of dialogic principles when establishing online relationships with stakeholders. Therefore, this paper sheds light on the dialogic potential that social networks provide in public sector, and particularly, it offers a guide regarding how local government should implement Twitter to foster the dialogic communication with citizens.     

Social Capital and Institutional Trust: Evidence from Bolivia's Popular Participation Decentralisation Reforms

This article uses Bolivia's emblematic process of decentralisation (Popular Participation) to explore the elusive relationship between interpersonal and institutional trust, as central components of social capital. The evidence corroborates the notion that basic social interaction and more complex institutional settings are strongly co-related, such as the trust that individuals place in their governments and institutions. The data also shows that social capital has a direct effect on civic activism and political behaviour at the individual level. The notion of social capital is present throughout the analysis as this type of capital allows observing and measuring changes in social structures that affect more complex institutional arrangements.     

Single‐Image Rectification Technique in Forensic Science

Many researchers have been working in Spain to document the communal graves of those assassinated during the Spanish Civil War. This article shows the results obtained with two low‐cost photogrammetric techniques for the basic documentation of forensic studies. These low‐cost techniques are based on single‐image rectification and the correction of the original photo displacement due to the projection and perspective distortions introduced by the lens of the camera. The capability of image rectification is tested in an excavation in the village of Loma de Montija (Burgos, Spain). The results of both techniques are compared with the more accurate data obtained from a laser scanner system RIEGL LMS‐Z390i to evaluate the error in the lengths. The first technique uses a camera situated on a triangle‐shaped pole at a height of 5 m and the second positions the camera over the grave using a linearly actuated device. The first technique shows measurement errors less than 6%, whereas the second shows greater errors (between 8% and 14%) owing to the positioning of the carbon‐fiber cross on an uneven surface.     

Relationship Between Intimate Partner Violence, Depressive Symptomatology, and Personality Traits

The aim of this study was to examine the relationship between intimate partner violence (IPV) and personality disorder symptoms controlling for depressive state. Victims of IPV (n?=?176) and non-abused women (n?=?193) completed the Dimensional Assessment of Personality Pathology-Basic Questionnaire (DAPP-BQ), Index of Spouse Abuse (ISA), and Beck Depression Inventory-II (BDI-II). IPV victims scored higher than non-abused women on Intimacy Problems, and scored lower on Rejection traits, after adjustment for depressive symptoms. Severity of the IPV was related to Cognitive Distortion, Suspiciousness, Restricted Expression, and Intimacy Problems, and the length of the IPV was negatively associated with Rejection. The current study suggests only modest differences in personality traits between IPV and non-abused women. The DAPP-BQ traits associated with severity of IPV, in a dose-response manner, would partially reflect the symptoms of complex post-traumatic stress disorder (CPTSD), although this possibility deserves further study.     

The electoral consequences of corruption scandals in Spain

Previous studies of the electoral consequences of corruption in Spanish local elections (Jiménez Revista de Investigaciones Políticas y Sociológicas, 6(2):43–76, 2007; Fernández-Vázquez and Rivero 2011, Consecuencias electorales de la corrupción, 2003–2007. Estudios de Progreso, Fundación Alternativas; Costas et al. European Journal of Political Economy: 28(4):469-484, 2012) have found that voters do not necessarily punish corrupt mayors. As has been pointed out in the comparative literature, the average loss of electoral support by corrupt incumbents is small and does not prevent their reelection most of the times (Jiménez and Caínzos 2006, How far and why do corruption scandals cost votes? In Garrard, J. and Newell, J. (eds.) Scandals in past and contemporary politics. Manchester: Manchester University Press). What remains unsolved, however, is the remarkable variability in this pattern. This article explores some of the micro-level variables that may mediate the effect of corruption scandal on the votes. We focus on three factors: ideological closeness to the incumbent party, political sophistication, and employment status. Our results provide only partial support for our hypotheses, suggesting that the effects of corruption are much more complex than what may seem at first sight.     

Biological variability of the minutiae in the fingerprints of a sample of the Spanish population

The minutiae, a term coined by Galton to refer to the small peculiarities present along the length of every isolated ridge, or characteristic points, a term used primarily by the Spanish Police Scientists, have an inter- and intrapopulation variability which has not been extensively studied. However, these peculiarities constitute the bases for the fingerprint identification of individuals in the field of criminology. Using the adhesive paper and graphite method, the fingerprints of 200 students, 100 males and 100 females, with ages ranging between 20 and 35, have been taken at the University of Alcala (Madrid). From this sample, the distal phalanx of the index finger of the right hand has been studied. The total count of the minutiae, as well as that of each different type, was made of the entire print area, and inside and outside of a circle with a radius of 18 ridges. The highest frequencies were of ridge endings, followed by bifurcations and convergences, all others appearing with frequencies of lower than 5%. The distribution of the minutiae was not homogeneous for the area of the fingerprint (inside and outside the circle). In the study of minutiae statistically significant differences were found between the sexes, and between the different types of general pattern (arches, loops, and whorls).     

Allele frequencies of six miniSTR loci (D10S1248, D14S1434, D22S1045, D4S2364, D2S441 and D1S1677) in a Spanish population

Allele frequencies and forensic parameters for six miniSTR autosomal loci (D10S1248, D14S1434, D22S1045, D4S2364, D2S441 and D1S1677) were obtained from a sample of 264 unrelated individuals from Spain. No significant deviations from Hardy-Weinberg expectations were found. Due to the small PCR products (<125 bp), the use of these non-CODIS (NC) miniSTRs can increase the probability that a degraded sample can be typed. Additionally, these systems can be used in routine paternity analyses where more markers are needed to increase the power of exclusion or in complex paternity cases (e.g. involving closely related individuals).     

“The big sleep: Elucidating the sequence of events in the first hours of death to determine the postmortem interval”

Recent developments on postmortem interval estimation (PMI) take an advantage of the autolysis process, pointing out to the analysis of the expression of apoptosis and autophagy genes towards this purpose. Oxidative stress plays a role in this signaling as a regulatory mechanism and/or as a consequence of cell death. Additionally, melatonin has been implicated on apoptosis and autophagy signaling, making melatonin a suitable target for PMI determination. The aim of this study was to investigate the early PMI through the analysis of the expression of autophagy genes as well as oxidative stress and melatonin receptor. Our results demonstrated a rapidly increased on the expression of autophagy genes according to the expected sequence of events, then a marked decrease in this expression, matched with the switch to the apoptosis signaling. These results revealed potential candidates to analyze the PMI in the first hours of death, helping to estimate the time-since-death.     

Attitudes,Perceptions, and Preferences of Individuals from Temuco (Chile) About Denture Marking

Denture marking (DM) helps identify edentulous people with different methods. Analyzing perceptions and attitudes of denture wearers would enable understanding of the practical aspects, an analysis still absent in South America. Fifty‐three individual candidates for removable dentures were instructed on disaster victim identification (DVI) and the usefulness of DM for this purpose. They were physically shown eight DM systems and a questionnaire to which they responded by highlighting preferences in those systems. Although 98.11% did not know that dentures could be marked, only 9.43% denied interest in some type of DM. The 90.57% would mark their dentures with some system, preferring the inclusion of QR codes or a micro SIM card. The proven weaknesses of DVI and propensity for disaster mean this community in Chile is an opportunity to implement DM systems. Obstacles may come not from patients but from their dentists, educational institutions, or a lack of public policies.     

Disentangling the Role of Ideology and Partisanship in Legislative Voting: Evidence from Argentina

We present a novel approach to disentangle the effects of ideology, partisanship, and constituency pressures on roll‐call voting. First, we place voters and legislators on a common ideological space. Next, we use roll‐call data to identify the partisan influence on legislators' behavior. Finally, we use a structural equation model to account for these separate effects on legislative voting. We rely on public opinion data and a survey of Argentine legislators conducted in 2007–08. Our findings indicate that partisanship is the most important determinant of legislative voting, leaving little room for personal ideological position to affect legislators' behavior.
