Is the Left-Right Scale a Valid Measure of Ideology?

In order to measure ideology, political scientists heavily rely on the so-called left-right scale. Left and right are, however, abstract political concepts and may trigger different associations among respondents. If these associations vary systematically with other variables this may induce bias in the empirical study of ideology. We illustrate this problem using a unique survey that asked respondents open-ended questions regarding the meanings they attribute to the concepts “left” and “right”. We assess and categorize this textual data using topic modeling techniques. Our analysis shows that variation in respondents’ associations is systematically related to their self-placement on the left-right scale and also to variables such as education and respondents’ cultural background (East vs. West Germany). Our findings indicate that the interpersonal comparability of the left-right scale across individuals is impaired. More generally, our study suggests that we need more research on how respondents interpret various abstract concepts that we regularly use in survey questions.     

Changes in the dimensions of political competition in Europe and their impact on citizens’ engagement via Facebook

ABSTRACT

This article focuses on a little-explored area of research, seeking to explain how political changes influence the participation of citizens in the social networks of local governments. In the context of the recent upsurge of anti-system movements and political parties in the European Union, we analyse a new set of data on participation via local governments’ Facebook pages during a turbulent period in European politics. The results obtained show that when a local government is affected by changes in political competition there is a greater degree of citizens’ engagement through social networks. Our analytical framework shows that this increased engagement is directly associated with the vulnerability of political parties, especially when the governing party loses its absolute majority and is constrained or prevented from carrying out political initiatives.

Detection of Pb,Ba, and Sb in Cadaveric Maggots and Pupae by ICP-MS*

The concentrations of lead (Pb), barium (Ba), and antimony (Sb), characteristic of GSR, were determined in soil sediments and immature (larvae) of cadaveric flies of the family Calliphoridae, by inductively coupled plasma mass spectrometry (ICP-MS). This research refers to a case study from two real crime scenes in which the corpses were in an advanced state of decomposition. In case 1, the victim had holes similar to gunshot wounds, and in case 2, there was no evidence of perforations in the corpse. Soil sediment collection was performed at three different points of the terrain, at a minimum distance of 10 m from the corpse, for cases 1 and 2. In relation to the collection of immatures, larvae were collected in regions of the mouth, nose, and orifices similar to the entry of firearms projectile into the body, for case 1, and collection of larvae and pupae, located on the body and underneath it, for case 2. It was possible to detect and quantify the three elements of interest (Pb, Ba, and Sb) by ICP-MS in both sediment and cadaveric larvae. Concentrations of 4.44, 8.74, and 0.08 μg/g were obtained for Pb, Ba, and Sb, respectively, in the soil for case 1. For the case 2, the concentrations in Pb, Ba, and Sb were from 16.34 to 26.02 μg/g; from 32.64 to 57.97 μg/g and from 0.042 to 0.30 μg/g, respectively. In the larvae, Pb, Ba, and Sb were quantified in cases 1 and 2 with a concentration of 6.28 and 1.78 μg/g for Pb, 1.49 and 2.94 μg/g for Ba, 0.50 μg/g and <LD for Sb, respectively. These new results present the detection of characteristic elements of GSR in cadaveric larvae in humans in a real crime scene, besides highlighting the importance of the study of immature flies, using the ICP-MS technique in forensic analysis.     

Perceptions of Intragroup Rejection and Coping Strategies: Malleable Factors Affecting Hispanic Adolescents’ Emotional and Academic Outcomes

Understanding psychosocial factors that affect the academic achievement of Hispanic adolescents remains a nationwide priority in the United States. Extending previous studies of the stressful effects of perceived discrimination, this year-long longitudinal study examined the correlates of perceived ethnic in-group rejection, coping strategies and fatalistic beliefs, on depressive symptoms, grades, and college aspirations of 2,214 Hispanic adolescents (54 % female) in Southern California. Based on the transactional model of stress and coping and on self-perception theory, structural equation models revealed that high perceived intragroup rejection (10th grade) and low levels of active coping (11th grade) were associated with depressive symptoms in 11th grade. Also, depressive symptoms partially mediated the link between intragroup rejection and both academic outcomes. Avoidant coping strategies (e.g., watching TV) also predicted depressive symptoms and were positively related to fatalism. In addition, fatalism was negatively related to grades and aspiration to attend college. The findings suggest the need to help adolescents find adequate outlets for communication and to create awareness about the potential effects of intragroup rejection.     

The relationship between human trafficking and child recruitment in the Colombian armed conflict

The article rethinks the relationship between human trafficking as organised crime and child recruitment as a war crime. After analysing the records of 132 cases of child and adolescent recruitment brought before Colombia’s ordinary justice system between 2008 and 2016, it became clear that the youngsters involved had performed activities both directly and indirectly related to the conflict, but also that they had been exploited and maltreated, with no control over their situation. Reassessment of the relationship between human trafficking and child recruitment could result in more effective justice for this population by shedding light on alternate ways to construct reparation and reintegration.     

The use of local direct democracy in the Czech Republic: how NIMBY disputes drive protest behaviour

Over the past 15 years there has been an increase in the use of local direct democracy in the Czech Republic. The analysis shows that the primary cause has been the regulation of development projects. Using transaction costs economics (TCE) approach it is shown how the regulation related to the siting of development projects leads to a not-in-my-backyard (NIMBY) response resulting in political activism that uses institutions of local direct democracy. Drawing from the TCE perspective, in this article it is argued that the key sources of this political mobilisation have been the existence of contractual hazards related to development projects and an inability to form credible commitments between developers and communities. The article highlights a previously neglected explanation for the increased use of direct democracy because sources outside the political system often go unnoticed and contributes to the research on NIMBY disputes and on the expansion of direct democracy.     

Terrorist Attacks on the Energy Sector: The Case of Al Qaeda and the Islamic State

The article focuses on the attitudes of two militant Islamist groups, Al Qaeda and the Islamic State, toward the issue of terrorist attacks in the energy sector. The main aim of the article is both to analyze the importance of attacks on energy infrastructure for the strategies of these two organizations, and to describe specific examples and manifestations of terrorist activities from the side of Al Qaeda and the Islamic State with regard to the energy sector in the Middle East and North Africa. The article is based on the concept of terrorist attacks on the energy sector.
