Collaborative evolution: the context surrounding the formation and the effectiveness of a school partnership in a divided community in Northern Ireland

This paper examines an initiative promoting collaboration between schools located in a city setting in Northern Ireland, which is broadly divided along ethnic and political lines. The schools involved, like the vast majority of schools in Northern Ireland, educate Protestant and Catholic children separately. This presents particular challenges for school collaboration as it implies the establishment of new, connected relationships in an education system, which is historically and contemporaneously more characterised by division. Since 2007, the schools in this study have been involved in an education initiative which promotes cross-sectoral shared learning in core areas of the curriculum with a view to promoting school improvement; the additional, indirect goal is also about improving community relations. However, over this period, the relationship between the institutions has deepened, leading schools to examine how they can sustain partnership and evolve collaborative practice. This paper explores how the partnership has evolved and assesses its effectiveness as a collaborative enterprise. The paper concludes by demonstrating how effective collaboration between schools in Northern Ireland mitigates the potentially negative impacts of educating children separately, but also how effective models of school collaboration are capable of providing enhanced learning opportunities for pupils and are also capable of developing the communities in which they are located.

Trying similarity, doing difference:The role of interviewer self-disclosure in interview talk with young people

Advocates of semi-structured interview techniques have often argued that rapport may be built, and power inequalities between interviewer and respondent counteracted, by strategic self-disclosure on the part of the interviewer. Strategies that use self-disclosure to construct similarity between interviewer and respondent rely on the presumption that the respondent will in fact interpret the interviewer's behaviour in this way. In this article we examine the role of interviewer self-disclosure using data drawn from three projects involving interviews with young people. We consider how an interviewer's attempts to ‘do similarity’ may be interpreted variously as displays of similarity or, ironically, as indicators of difference by the participant, and map the implications that this may have for subsequent interview dialogue. A particular object of concern relates to the ways in which self-disclosing acts may function in the negotiation of category entitlement within interview interactions.

Incorporating Severity and Risk as Factors to the Fardal Cost-Effectiveness Model to Create a Cost-Benefit Model for Periodontal Treatment

Background: A previously described economic model was based on average values for patients diagnosed with chronic periodontitis (CP). However, tooth loss varies among treated patients and factors for tooth loss include CP severity and risk. The model was refined to incorporate CP severity and risk to determine the cost of treating a specific level of CP severity and risk that is associated with the benefit of tooth preservation.

Methods: A population that received and another that did not receive periodontal treatment were used to determine treatment costs and tooth loss. The number of teeth preserved was the difference of the number of teeth lost between the two populations. The cost of periodontal treatment was divided by the number of teeth preserved for combinations of CP severity and risk.

Results: The cost of periodontal treatment divided by the number of teeth preserved ranged from (US) $ 1,405 to $ 4,895 for high or moderate risk combined with any severity of CP and was more than $ 8,639 for low risk combined with mild CP. The cost of a three-unit bridge was $ 3,416, and the cost of a single-tooth replacement was $ 4,787.

Conclusion: Periodontal treatment could be justified on the sole basis of tooth preservation when CP risk is moderate or high regardless of disease severity.

A Spherical Array Approach for Simulation of Binaural Impulse Responses using the Finite Difference Time Domain Method

The finite difference time domain (FDTD) method has direct applications in musical instrument modeling, simulation of environmental acoustics, room acoustics and sound reproduction paradigms, all of which benefit from auralization. However, rendering binaural impulse responses from simulated
data is not straightforward to accomplish as the calculated pressure at FDTD grid nodes does not contain any directional information. This paper addresses this issue by introducing a spherical array to capture sound pressure on a finite difference grid, and decomposing it into a plane-wave density
function. Binaural impulse responses are then constructed in the spherical harmonics domain by combining the decomposed grid data with free field head-related transfer functions. The effects of designing a spherical array in a Cartesian grid are studied, and emphasis is given to the relationships
between array sampling and the spatial and spectral design parameters of several finite-difference
schemes.

Gender and Public Space in Divided Cities

The paper addresses two connected questions: firstly, in what ways might ‘public’ and ‘private’ spaces in cities be gendered; and secondly, what might this mean for the possibilities for complex forms of civility in a divided city such as Belfast? The specific focus on gendered dynamics of entitlement to inhabit urban space in this paper begins with some consideration of debates about the quality and experience of everyday life in cities, and the emergence of commonsense notions of ‘public’ and ‘private’ behaviour. Following this, key research concerned with the gendered dynamics of claimed collective, and particularly national, identities are outlined, in order to consider the significance of this literature for any study of the gender dynamics of life in a contested political context such as Belfast.

Difference equation approach to two-thermocouple sensor characterization in constant velocity flow environments

Thermocouples are one of the most popular devices for temperature measurement due to their robustness, ease of manufacture and installation, and low cost. However, when used in certain harsh environments, for example, in combustion systems and engine exhausts, large wire diameters are required, and consequently the measurement bandwidth is reduced. This article discusses a software compensation technique to address the loss of high frequency fluctuations based on measurements from two thermocouples. In particular, a difference equation (DE) approach is proposed and compared with existing methods both in simulation and on experimental test rig data with constant flow velocity. It is found that the DE algorithm, combined with the use of generalized total least squares for parameter identification, provides better performance in terms of time constant estimation without any a priori assumption on the time constant ratios of the thermocouples.

Intermarriage in a Divided Society: Ireland a Century Ago

This paper explores the characteristics associated with marriages between Roman Catholics and members of other religious denominations in Ireland before the Great War. Using the entire digitized returns of the 1911 population census, we find that such marriages were relatively rare, occurring in less than one percent of total marriages. Some of this infrequency can be attributed to ethno-religious hostility-especially in the north of the country. However, we also show that the rarity of intermarriage reflects local marriage markets, as non-Roman Catholics living in communities with fewer coreligionists were more likely to intermarry. We examine the individual characteristics of partners in these marriages, looking at the religious denomination of their children, their decision to marry out, and their fertility behavior. Our findings illustrate how the frequency of intermarriage reflects historical levels of intolerance, but only after local marriage market conditions have been accounted for.

Potentially Voting across the Divide in Deeply Divided Places: Ethnic Catch-All Voting in Consociational Northern Ireland

I elaborate a model of cross-bloc party support in deeply divided places. The model expects that the variation in the level of electoral support that citizens in Community A have for parties in Community B is a function of citizens' evaluations of the relative ability of parties in Community B to represent the interests of all communities. This 'ethnic catch-all' model of cross-bloc party support is tested in the context of consociational Northern Ireland, using data from a representative survey conducted directly after the 2010 Westminster general election. The findings are asymmetric: the model explains Protestant support for nationalist parties but not Catholic support for unionist parties. The findings, and their implications, are discussed.
