Religious segregation and teacher education in Northern Ireland

This paper surveys the extent of religious segregation in teacher education in Northern Ireland and notes that there are elements of separation within a general context of (increasing) common teacher education. With reference to liberal and communitarian theories the case for separate teacher education is considered. It is acknowledged that a case can be made for forms of separate teacher education in a liberal society but that certain limits or expectations should apply. A common teacher education is found to be desirable but it is suggested that in order to justify its dominant status in a plural environment it must be accommodating of religion, encourage dialogical engagement around concepts of shared fate and cultivate a sense of community. © 2010 Taylor & Francis.

Uniformity and diversity in religious education in Northern Ireland

This paper considers the tension that can exist in the aims of religious education between the desire to encourage open-minded, critical thinking through exposure to diverse traditions, ideas and cultures and the encouragement, overt or otherwise, into uniformity whereby learners take on the values of a particular tradition, culture or ideology (say of a religion, family or school). The particular situation of teaching religious education to post-primary school pupils in Northern Ireland is considered, and evidence cited to suggest that the Northern Ireland Core Syllabus in Religious Education has tried to impose a particular non-denominational Christian uniformity on pupils and teachers through its use of religious language. This has contributed to a culture of 'avoidance' in relation to the teaching of broad Christian diversity. The article concludes that there is a need for an ongoing and meaningful dialogue to discover what kind of balance between uniformity and diversity is best in teaching religious education in Northern Ireland, and notes that this also requires the reassessment of fundamental issues such as the aims of education and the relationship between secular and religious values in publicly funded schools. © 2004 Christian Education.

Electrowetting movement of an aqueous droplet between two three-dimensional electrode surfaces

In an effort to develop a novel electronic paper image display technology based on the electrowetting principle, a 3-D electrowetting cell is designed and fabricated, which consists of two 3-D bent electrodes, each having a horizontal surface made of gold and a vertical surface made of indium tin oxide (ITO) glass as a color display window, a layer of dielectric material on the 3-D electrodes, and a highly fluorinated hydrophobic layer on the surface of the dielectric layer. Results of this work show that an electrowetting-induced motion of an aqueous droplet in immiscible oils can be achieved reversibly across the boundary of the horizontal and vertical surfaces of the 3-D electrode surface. It is also shown that the droplet can maintain its wetting state on a vertical sidewall electrode free of a power supplier when the voltage is removed. This phenomenon may form the basis for color contrast modulation applications, where a power-free image display is required, such as electronic paper display technology in the future.

The continued salience of religious voting in the United States, Germany, and Great Britain

Conventional wisdom on party systems in advanced industrial democracies holds that modern electorates are dealigned and that social cleavages no longer structure party politics. Recent work on class cleavages has challenged this stylized fact. The analysis performed here extends this criticism to the religious-secular cleavage. Using path analysis and comparing the current electorates of the United States, Germany, and Great Britain with the early 1960s, this paper demonstrates that the religious-secular cleavage remains or has become a significant predictor of conservative vote choice. While the effects of the religious-secular cleavage on vote choice have become largely indirect, the total of the direct and indirect effects is substantial and equivalent to the effects of class and status.

Parties, cleavages, and issue evolution: The case of the religious-secular cleavage in Chile

Several recent articles have reached different conclusions regarding the impact of the religious–secular cleavage in Chile. The resolution of this debate has important consequences for the understanding of cleavages. Studies subscribing to the view that parties have considerable agency in the maintenance of cleavages have found that religiosity no longer affects vote choice, while studies rooted in a sociological perspective argue that religiosity still matters. We show that the reason for the discrepant results is because a partisan realignment is underway, whereby religious voters are gradually shifting their loyalties from the parties of the left to the parties of the right, matching a division that has taken place at the elite level. These results are consistent with an issue evolution perspective, which provides a clearer articulation of how cleavages form than either the agency or the sociological approaches.

Party agency and the religious-secular cleavage in post-Communist countries: The case of Romania

Research focusing on several post-communist countries has found evidence of social cleavage effects on political behaviour similar to those found in Western Europe. In some post-communist countries, however, social cleavage effects appear far weaker (if at all). To understand why this is the case, I perform a case study of Romania, focusing on the religious–secular cleavage. Drawing upon research that emphasises the role of parties in forming cleavages, I argue that the reason for the absence of social cleavage effects is due to party competition for the same group of voters by parties from opposing ends of the ideological spectrum. By shifting their positions, some parties have prevented the appearance of cleavages by shaping individuals' perceptions of the parties and, in doing so, have even altered individuals' own left–right self-placements.

Movement and Orientation

The ways in which fish use space in nature are described, distinguishing between movements within a home range, dispersal and directed migration, as are the mechanisms that determine how fish use space. The external stimuli to which fish respond, how they use these cues to find their way around and the role of hormones in migration are also covered. An account is then given of how movement and orientation change with age, the evidence for inherited differences in these aspects of behaviour and environmental effects on development of space use patterns. The benefits that accrue to fish from moving in particular ways are described, as are adverse consequences of such movements, in the form of energetic costs and exposure to predators and pathogens. The ways in which benefits and costs are balanced against each other are discussed, with special reference to diurnal vertical migration. Although cultured fish usually inhabit confined spaces, their natural patterns of orientation and movement can cause a number of problems in aquaculture and some of these are described. Such problems are amenable to biological solutions and these are considered in the final section of this chapter, which also looks at the potential for using what is known about how fish move about to improve the effectiveness of general husbandry practices.

Classifying pedestrian movement behaviour from GPS trajectories using visualization and clustering

The quantity and quality of spatial data are increasing rapidly. This is particularly evident in the case of movement data. Devices capable of accurately recording the position of moving entities have become ubiquitous and created an abundance of movement data. Valuable knowledge concerning processes occurring in the physical world can be extracted from these large movement data sets. Geovisual analytics offers powerful techniques to achieve this. This article describes a new geovisual analytics tool specifically designed for movement data. The tool features the classic space-time cube augmented with a novel clustering approach to identify common behaviour. These techniques were used to analyse pedestrian movement in a city environment which revealed the effectiveness of the tool for identifying spatiotemporal patterns. © 2014 Taylor & Francis.

Interpreting pedestrian behaviour by visualising and clustering movement data

Recent technological advances have increased the quantity of movement data being recorded. While valuable knowledge can be gained by analysing such data, its sheer volume creates challenges. Geovisual analytics, which helps the human cognition process by using tools to reason about data, offers powerful techniques to resolve these challenges. This paper introduces such a geovisual analytics environment for exploring movement trajectories, which provides visualisation interfaces, based on the classic space-time cube. Additionally, a new approach, using the mathematical description of motion within a space-time cube, is used to determine the similarity of trajectories and forms the basis for clustering them. These techniques were used to analyse pedestrian movement. The results reveal interesting and useful spatiotemporal patterns and clusters of pedestrians exhibiting similar behaviour.
