Child Poverty in Northern Ireland: Results from the Poverty and Social Exclusion Study

- There is general agreement that the measurement of child poverty is based on both low income and deprivation.

- Adjusting incomes for different household types, measuring before or after housing costs, and the selection of deprivation items all have an impact on poverty rates.

- The consensual poverty method, which takes account of what the population considers to be basic necessities, is described. The study found a high level of agreement on the basic necessities for children.

- The study found that only a few children lacked very basic necessities such as three meals a day and adequate clothing, but a third of all children (150,000) were deprived of an annual holiday and 75,000 children are growing up in cold and damp homes.

- Overall, the study found that 24% or 106,000 children are living in low income households and are deprived of four or more items.

- The study found those who had a ‘high experience’ of the conflict were significantly more deprived than those with no conflict experience and that a fifth of all children are living with an adult/s who have ‘high experience’.

Teenagers' Perceptions and Experiences of Belfast as a Divided City

In this ‘research project’ case study, we provide an empirical example of how quantitative and qualitative methods were combined within a single study and discuss some of the strengths and weaknesses of our combined methodology which included questionnaires, photo-prompts and focus-group interviews. Our intention in using mixed methods was to enhance understandings of the meanings of space, place and territory on the everyday lives of young people growing up in Belfast. How do young people negotiate space in politically divided cities such as Belfast? Is territory important, and if so, why is it important? How do we construct an appropriate and relevant study design that can not only describe, but explain what place, space and territory mean to young people, and more importantly, how it impacts on their everyday lives? How useful is it to apply a mixed-methods approach to finding answers to these questions? We explain why and how we used a mixed-methods approach and illuminate some of the issues we encountered. We demonstrate how mixed methods can provide not just complementary but also new insights into the topic under investigation. We hope that the case study encourages you to experiment, or at least consider, the potential of using mixed methods.

Determinants of uptake and maintenance of active commuting to school

The objective was to identify determinants of uptake and maintenance of active school travel (AST) over 4 years in children aged 9 at baseline. Data from wave 1 (n=8502) and 2 (n=7479) of the Growing Up in Ireland study were analysed. At 9- and 13-years 25% and 20% engaged in AST. Children were more likely to maintain or take-up AST if they lived in an urban area. Change in distance to school influenced both maintenance and adoption of AST, with a negative impact seen for increased distance between 9 and 13 years and a positive impact seen for decreased distance. Some factors which predict uptake and maintenance of AST are modifiable and can inform intervention development.

The career indecision profile : measurement equivalence in two international samples

This study tested for the measurement equivalence of a four-factor measure of career indecision (Career Indecision Profile-65 [CIP-65]) between a U.S. sample and two international samples; one composed of French-speaking young adults from France and Switzerland and the other of Italian ado- lescents. Previous research had supported the four-factor structure of the CIP-65 in both the United States and Iceland but also showed that items on two of the four scales may be interpreted differently by young adults growing up in these two countries. This study extends previous research by testing whether the four CIP-65 factors are measured equivalently in two additional international samples. Results largely supported the configural and metric invariance of the CIP-65 in the United States and international samples, but several scales showed a lack of scalar invariance. Some explanations are offered for these findings along with suggestions for future research and implications for practice.

South Asian Women's Identities: A Media and Personal Narrative Analysis

This study examines issues of racism and sexism through the lens of Critical Race Theory and the interaction of personal and composite narratives. Specifically, the study explores how mainstream media’s hegemonic portrayal of South Asian culture and the 2007 socalled honour killing of Aqsa Parvez contribute to post-9/11 Islamophobia. The researcher presents a personal narrative that draws upon her experiences growing up in Dubai, U.A.E., and in Ontario, Canada and critically analyzes majoritarian stories related to Parvez as well as “counter-perspectives” that challenge such views. Study findings highlight the impact of 9/11 and Parvez’s murder on the researcher’s identity formation, and how media portray Muslim women as oppressed beings who live under the yoke of patriarchy. Results also indicate that although certain articles offer a counter-perspective that challenge dominant narratives, most recent media representations of the Parvez story equate Islam with honour killings and thus foster continued Islamophobia.

Narratives of Experience in Education: Living and Working Through Poverty in a Rural Community

In this study, I use my own experiences in education as a former elementary student, research assistant, and as a current secondary school teacher, to examine how living in a marginalised rural community challenged by poverty affected my formal education. The purpose of this study was to use stories to: (a) explore my formative elementary education growing up in a community that was experiencing poverty, and; (b) to examine the impact and implications of these experiences for me as a teacher and researcher considering the topic of poverty and education. This study used narrative inquiry to explore stories of education, focusing on experiences living and working in a rural community. My role in the study was both as participant and researcher as I investigate, through story, how I was raised in a marginalised, rural community faced with challenges of poverty and how I relate to my current role as a teacher working in a similar, rural high school. My own experiences and reflections form the basis of the study, but I used the contributions of secondary participants to offer alternative perspective of my interpretation of events. Participants in this study were asked to write about and/or retell their lived stories of working in areas affected by challenging circumstances. From my stories and those of secondary participants, three themes were explored: student authorship, teaching practice, and community involvement. An examination of these themes through commonplaces of place, sociality and time (Connelly and Clandinin, 2006) provide a context for other educators and researchers to consider or reconsider teaching practices in school communities affected by poverty.

Participation as capacity-building for active citizenship

Within the framework of the “capability approach” to human rights, this paper argues that adults who facilitate participatory planning and design with children and youth have an ethical obligation to foster young people’s capacities for active democratic citizenship. Practitioners often worry, justifiably, that if young people fail to see their ideas realized, they may become disillusioned and alienated from political life. Based on the experience of the Growing Up in Cities program of UNESCO, four rules of good practice are distilled which can help promote young people’s belief in the value of collective action, regardless of the challenges that the full implementation of their ideas may face.

Agir de manière appropriée: la participation des jeunes à l'aménagement

La réflexion sur l’éthique et la participation des jeunes et des enfants à l’aménagement comporte au moins deux dimensions : d’une part, les justifications d’une telle participation ; d’autre part, les problèmes que la pratique participative fait émerger et face auxquels les cadres de référence conventionnels (non participatifs) ne sont pas toujours utiles. Le présent article aborde ces deux dimensions et explore leurs liens à la lumière de trois méthodes distinctes en matière de théorie morale, soit l’éthique déontologique, l’éthique conséquentialiste et l’éthique de la vertu. Sur la base d’une expérience participative d’aménagement inscrite dans le programme Grandir en Ville de l’UNESCO, certaines contradictions entre les principes d’une pratique participative avec des enfants et la manière dont les problèmes éthiques sont parfois gérés sont mises en évidence.

Retour à Montréal-Nord: un examen critique de mon expérience comme étudiant dans un projet participatif d'aménagement avec des jeunes

Cet article explore sous l’angle éthique les attentes, surprises et déceptions vécues par les étudiants inscrits à un atelier de design participatif avec des jeunes de 10-14 ans. Cette expérience, inscrite dans le programme Growing up in Cities, devait aboutir à des résultats de recherche et des projets d’aménagement réalistes en impliquant les jeunes comme collaborateurs dans la conception. Face à ces objectifs ambitieux, le bilan pour les jeunes est mitigé sur le plan des retombées et du caractère égalitaire des rapports. En revanche, on se rend compte que les étudiants ont cherché diverses manières de traiter les jeunes comme des personnes intelligentes, sensibles et autonomes. Cet article propose quelques pistes pour éclairer les choix en termes de démarche de participation.

Conséquences d’une restriction de croissance intra-utérine sur la réactivité aortique chez le rat en fonction de l’âge et du sexe biologique

Antécédents. Le tonus vasculaire est régulé par plusieurs mécanismes et réagit à plusieurs composés endogènes et exogènes, dont les hormones circulantes et les substances vasoactives libérées par l’endothélium. Plusieurs études ont démontré que les femmes pré-ménopausées seraient moins à risque d’avoir des maladies cardiovasculaires que les hommes et que cette protection serait due aux hormones stéroïdiennes oestrogéniques. De plus, des études démontrent que les artères gagnent en rigidité avec l’âge différemment selon le sexe et que la restriction de croissance intra-utérine (RCIU) prédispose au développement de maladies cardiovasculaires à l’âge adulte différemment chez les hommes et chez les femmes. On a cherché à savoir si la réactivité vasculaire aortique dépend du sexe biologique, de l’âge et de l’environnement intra-utérin et si la rigidité aortique est différente entre les mâles et les femelles. Méthode. Des anneaux d’aorte thoracique de rats mâles ou femelles, témoins ou RCIU, de 5, 12 et 20 semaines avec endothélium ont été montés dans des bains à organe isolé. La contraction à des doses croissantes de phényléphrine (Phe) avec ou sans L-Name ainsi que la relaxation à des doses croissantes de carbachol (Cbc) ou de nitroprussiate de sodium (SNP) ont été enregistrées afin d’évaluer la réactivité vasculaire de l’aorte et de comparer les différents groupes. Des anneaux d’aorte thoracique de rats mâles et femelles âgés entre 13 et 17 semaines ont été utilisées pour évaluer la rigidité artérielle. Résultats. Chez les rats mâles seulement, la contraction maximale à la Phe en absence et en présence du L-Name est augmentée à 20 semaines chez les témoins et à 12 et 20 semaines chez les RCIU. Chez les femelles, la contraction maximale n’est pas affectée par l’âge et la RCIU. Par contre, un effet du L-Name est observé à l’âge adulte, autant chez les femelles témoins que RCIU. L’effet du L-Name est plus prononcé chez les femelles que chez les mâles. Dans tous les groupes RCIU, la relaxation maximale au Cbc est réduite. Par contre, aucune différence entre les différents groupes n’est observée avec le SNP et aucune différence de rigidité n’est observée entre les mâles et les femelles. Conclusion. Les résultats au L-Name suggèrent un rôle plus important du NO chez les femelles et les résultats à la Phe suggèrent que les mâles sont plus réactifs aux stimulis vasoconstricteurs avec l’âge et que ceci est encore plus prononcé lorsque l’environnement intra-utérin a été défavorable. La différence de contraction maximale entre les mâles et les femelles n’est pas due à la rigidité artérielle.

Development of a Biometric Personal Authentication System Based on Fingerprint and Speech

Biometrics deals with the physiological and behavioral characteristics of an individual to establish identity. Fingerprint based authentication is the most advanced biometric authentication technology. The minutiae based fingerprint identification method offer reasonable identification rate. The feature minutiae map consists of about 70-100 minutia points and matching accuracy is dropping down while the size of database is growing up. Hence it is inevitable to make the size of the fingerprint feature code to be as smaller as possible so that identification may be much easier. In this research, a novel global singularity based fingerprint representation is proposed. Fingerprint baseline, which is the line between distal and intermediate phalangeal joint line in the fingerprint, is taken as the reference line. A polygon is formed with the singularities and the fingerprint baseline. The feature vectors are the polygonal angle, sides, area, type and the ridge counts in between the singularities. 100% recognition rate is achieved in this method. The method is compared with the conventional minutiae based recognition method in terms of computation time, receiver operator characteristics (ROC) and the feature vector length. Speech is a behavioural biometric modality and can be used for identification of a speaker. In this work, MFCC of text dependant speeches are computed and clustered using k-means algorithm. A backpropagation based Artificial Neural Network is trained to identify the clustered speech code. The performance of the neural network classifier is compared with the VQ based Euclidean minimum classifier. Biometric systems that use a single modality are usually affected by problems like noisy sensor data, non-universality and/or lack of distinctiveness of the biometric trait, unacceptable error rates, and spoof attacks. Multifinger feature level fusion based fingerprint recognition is developed and the performances are measured in terms of the ROC curve. Score level fusion of fingerprint and speech based recognition system is done and 100% accuracy is achieved for a considerable range of matching threshold

Aspekte des Prozesses der N-Freisetzung aus Humus-Vorratsabbau

In der vorliegenden Arbeit werden die Auswirkungen von Umweltveränderungen in einem N-gesättigten Buchenwaldökosystem über Basalt (Braunerde) untersucht. Unter veränderten Umweltbedingungen sind hier vor allem Bestandesdachauflösung, immissions- oder waldbaulich bedingt, und Klimaveränderung zu verstehen, die eine Erwärmung des Oberbodens zur Folge haben. Die Änderungen der Umweltbedingungen werden in diesem Versuchsansatz durch einen waldbaulichen Eingriff simuliert, durch den eine Bestandeslücke entsteht, die in einer Erwärmung des Bodens resultieren und damit den Wasser- und Elementhaushalt insgesamt beeinflussen. Es wird deutlich, dass die in der vorliegenden Arbeit untersuchten Flächen als N-gesättigt bezeichnet werden können, da die N-Verluste aus dem System die Größe der Einträge überschreiten. In der Folge ist es zu einer Entkopplung des Stoffhaushalts und damit zu erhöhter N-Mobilisierung gekommen. Diese konnte vor allem im hydrologischen Jahr 1996 dokumentiert werden; der Überschuss-N-Output liegt auf der Auflichtungsfläche bei bis zu 50 kg N/(ha*a)! Die beobachteten hohen N-Austräge erfolgten trotz eines ebenfalls beobachteten Anwachsens des mikrobiellen Stickstoff-Pools und des Aufwachsens einer krautigen und strauchigen Vegetation auf der Auflichtungsfläche. Im Jahresgang konnten auf der Auflichtungsfläche in 0 - 30 cm Bodentiefe maximale Änderungen im Nmic-Vorrat von 130 kg N/(ha*a) beobachtet werden. Das im Frühjahr beginnende quantitative Anwachsen des mikrobiellen Stickstoff-Pools mit dem Jahresgang zeigt vor allem dessen Temperaturabhängigkeit auf. Die am Ende der Vegetationsperiode deutlich ansteigenden Austragsraten zeigen jedoch an, dass der freigesetzte Stickstoff auch von den Mikroorganismen nicht dauerhaft im System gehalten werden kann, da mit fallender Temperatur auch die Mikroorganismen absterben und der in ihrer Biomasse gespeicherte Stickstoff freigesetzt wird. Aufwachsende Vegetation auf der Auflichtungsfläche konnte einen Großteil des Netto-Stickstoff-Jahreseintrages aufnehmen. Da die "Netto-Jahres-Mineralisation" 1996 leicht über der Wurzelaufnahme liegt, verbleibt ein Rest, der nicht von der aufwachsenden krautigen Vegetation der Auflichtungsfläche aufgenommen werden kann. Ergebnis ist damit, dass die auf Lochhieben aufwachsende krautige und strauchige Vegetation eine temperaturbedingte Stickstoffmobilisierung nur teilweise kompensieren kann. Allein aufwachsende verholzende Vegetation kann Stickstoff langfristig im System binden.
