    THE IMPACT OF BRITISH COUNTERTERRORIST STRATEGIES ON POLITICAL VIOLENCE IN NORTHERN IRELAND: COMPARING DETERRENCE AND BACKLASH MODELS,

    CRIMINOLOGY, Issue 1 2009
    GARY LAFREE
    Since philosophers Beccaria and Bentham, criminologists have been concerned with predicting how governmental attempts to maintain lawful behavior affect subsequent rates of criminal violence. In this article, we build on prior research to argue that governmental responses to a specific form of criminal violence,terrorism,may produce both a positive deterrence effect (i.e., reducing future incidence of prohibited behavior) and a negative backlash effect (i.e., increasing future incidence of prohibited behavior). Deterrence-based models have long dominated both criminal justice and counterterrorist policies on responding to violence. The models maintain that an individual's prohibited behavior can be altered by the threat and imposition of punishment. Backlash models are more theoretically scattered but receive mixed support from several sources, which include research on counterterrorism; the criminology literature on labeling, legitimacy, and defiance; and the psychological literature on social power and decision making. In this article, we identify six major British strategies aimed at reducing political violence in Northern Ireland from 1969 to 1992 and then use a Cox proportional hazard model to estimate the impact of these interventions on the risk of new attacks. In general, we find the strongest support for backlash models. The only support for deterrence models was a military surge called Operation Motorman, which was followed by significant declines in the risk of new attacks. The results underscore the importance of considering the possibility that antiterrorist interventions might both increase and decrease subsequent violence. [source]


    STRATEGIC PLANNING AND PERFORMANCE: AN EXPLORATORY STUDY OF HOUSING ASSOCIATIONS IN NORTHERN IRELAND

    FINANCIAL ACCOUNTABILITY & MANAGEMENT, Issue 1 2009
    Roger Courtney
    Based on qualitative data this paper explores the resons for the non-profit housing sectors enthusiastic embrace of strategic planning practices. Evidence is presented on the use of specified techiniques by housing associations in Northeren Ireland and their impact on the performance of the assocaitions. Without dismissing rational goel seeking explanations for adoption, the study concludes the strategic planning is also a legimation seeking practice. Evidence suggest that the contested nature of performance in the non-profit sector makes it hard for chief executives to sustain a rational goal based argument for adopting strategic planing.

    The roles of external ethnoguarantors and primary mediators in Cyprus and Northern Ireland

    CONFLICT RESOLUTION QUARTERLY, Issue 2 2006
    Sean J. Byrne
    This article discusses two different types of third-party interveners in the Cyprus and Northern Ireland conflicts. The comparative case study examines the roles of primary mediators who have the power and clout to enforce agreements and regional external ethnoguarantors who have cultural, historical, and political ties to internal allies.

    A survey of female patients in high security psychiatric care in Scotland

    CRIMINAL BEHAVIOUR AND MENTAL HEALTH, Issue 2 2001
    Dr Lindsay D.G. Thomson MD MPhil MRCPsych Senior Lecturer in Forensic Psychiatry Honorary Consultant Forensic Psychiatrist
    Background The State Hospital, Carstairs, is the sole high security psychiatric facility for Scotland and Northern Ireland. Method This study compares the female (n = 28) and male (n = 213) patients resident there between 1992 and 1993 using data derived from case-note reviews and interviews with patients and staff. Results Nearly three-quarters of both the male and female populations had a primary diagnosis of schizophrenia, and secondary diagnoses of substance abuse and antisocial personality disorder were common. Female patients were more frequently admitted from other psychiatric hospitals, had less serious index offences and more minor previous convictions, and were less likely to be subject to a restriction order. They had more often experienced depressive symptoms and had significantly greater histories of self-harm, physical and sexual abuse. At interview, nearly three-quarters had active delusions and over half had recently behaved in an aggressive manner. Almost 90% were said not to require the security of the State Hospital. Conclusions It was concluded that mental illness and adverse social circumstances had combined to create a very disadvantaged group of women in high security psychiatric care in Scotland. As a group these women were inappropriately placed and their requirement was for intensive, rather than high security psychiatric care. Copyright © 2001 Whurr Publishers Ltd. [source]

    Association of British Clinical Diabetologists (ABCD) and Diabetes-UK survey of specialist diabetes services in the UK, 2006.

    DIABETIC MEDICINE, Issue 6 2008

    Abstract Aims To identify the views and working practices of consultant diabetologists in the UK in 2006,2007, the current provision of specialist services, and to examine changes since 2000. Methods All 592 UK consultant diabetologists were invited to participate in an on-line survey. Quantitative and qualitative analyses of responses were undertaken. A composite ,well-resourced service score' was calculated. In addition to an analysis of all respondents, a sub-analysis was undertaken, comparing localities represented both in 2006/2007 and in 2000. Results In 2006/2007, a 49% response rate was achieved, representing 50% of acute National Health Service Trusts. Staffing levels had improved, but remained below recommendations made in 2000. Ten percent of specialist services were still provided by single-handed consultants, especially in Northern Ireland (in 50% of responses, P = 0.001 vs. other nations). Antenatal, joint adult,paediatric and ophthalmology sub-specialist diabetes services and availability of biochemical tests had improved since 2000, but access to psychology services had declined. Almost 90% of consultants had no clinical engagement in providing community diabetes services. The ,well-resourced service score' had not improved since 2000. There was continued evidence of disparity in resources between the nations (lowest in Wales and Northern Ireland, P = 0.007), between regions in England (lowest in the East Midlands and the Eastern regions, P = 0.028), and in centres with a single-handed consultant service (P = 0.001). Job satisfaction correlated with well-resourced service score (P = 0.001). The main concerns and threats to specialist services were deficiencies in psychology access, inadequate staffing, lack of progress in commissioning, and the detrimental impact of central policy on specialist services. Conclusions There are continued disparities in specialist service provision. Without effective commissioning and adequate specialist team staffing, integrated diabetes care will remain unattainable in many regions, regardless of reconfigurations and alternative service models.

    Secular trends, disease maps and ecological analyses of the incidence of childhood onset Type 1 diabetes in Northern Ireland, 1989,2003

    DIABETIC MEDICINE, Issue 3 2007
    C. R. Cardwell
    Abstract Aims To investigate secular trends in the incidence of Type 1 diabetes in Northern Ireland over the period 1989,2003. To highlight geographical variations in the incidence of Type 1 diabetes by producing disease maps and to compare incidence rates by relevant area characteristics. Methods New cases of Type 1 diabetes in children aged 0,14 years in Northern Ireland were prospectively registered from 1989 to 2003. Standardized incidence rates were calculated and secular trends investigated. Bayesian methodology was used to produce maps of disease incidence using small geographical areas (582 electoral wards). Ecological analyses were conducted using Poisson regression to investigate incidence rates by area characteristics at a finer geographical subdivision (5022 census output areas). Results In Northern Ireland during 1989,2003, there were 1433 new cases, giving a directly standardized incidence rate of 24.7 per 100 000 person-years. This incidence rate increased by a mean of 4.2% per annum. Disease maps highlighted higher incidence rates in the predominately rural north-east of the province and lower incidence rates in the urban areas around Belfast in the east and Derry in the north-west of the province. Ecological analysis identified higher incidence in rural areas (P < 0.001), areas with low migration rates (P = 0.002), affluent areas (P < 0.0001), sparsely populated areas (P = 0.0001) and remote areas (P = 0.005). Conclusions In Northern Ireland the incidence of Type 1 diabetes is increasing. The observed higher incidence in rural, affluent, sparsely populated and remote areas may reflect a reduced or delayed exposure to infections in these areas. [source]


    An economic evaluation of atenolol vs. captopril in patients with Type 2 diabetes (UKPDS 54)

    DIABETIC MEDICINE, Issue 6 2001
    A. Gray
    Abstract Aims To compare the net cost of a tight blood pressure control policy with an angiotensin converting enzyme inhibitor (captopril) or , blocker (atenolol) in patients with Type 2 diabetes. Design A cost-effectiveness analysis based on outcomes and resources used in a randomized controlled trial and assumptions regarding the use of these therapies in a general practice setting. Setting Twenty United Kingdom Prospective Diabetes Study Hospital-based clinics in England, Scotland and Northern Ireland. Subjects Hypertensive patients (n= 758) with Type 2 diabetes (mean age 56 years, mean blood pressure 159/94 mmHg), 400 of whom were allocated to the angiotensin converting enzyme inhibitor captopril and 358 to the , blocker atenolol. Main outcome measures Life expectancy and mean cost per patient. Results There was no statistically significant difference in life expectancy between groups. The cost per patient over the trial period was £6485 in the captopril group, compared with £5550 in the atenolol group, an average cost difference of £935 (95% confidence interval £188, £1682). This 14% reduction arose partly because of lower drug prices, and also because of significantly fewer and shorter hospitalizations in the atenolol group, and despite higher antidiabetic drug costs in the atenolol group. Conclusions Treatment of hypertensive patients with Type 2 diabetes using atenolol or captopril was equally effective. However, total costs were significantly lower in the atenolol group. Diabet.

    Aeolian fetch distance and secondary airflow effects: the influence of micro-scale variables on meso-scale foredune development

    EARTH SURFACE PROCESSES AND LANDFORMS, Issue 7 2008
    Kevin Lynch
    Abstract Unsuccessful attempts to use process-scale models to predict long-term aeolian sediment transport patterns have long been a feature of aeolian research. It has been proposed that one approach to overcome these problems is to identify micro-scale variables that are important at longer timescales. This paper assesses the contribution of two system variables (secondary airflow patterns and fetch distance) to medium-term (months to years) dune development. The micro-scale importance of these variables had been established during previous work at the site (Magilligan Strand, Northern Ireland). Three methods were employed. First, sand drift potentials were calculated using 2 years of regional wind data and a sediment transport model. Second, wind data and large trench traps (2 m length × 1 m width × 1·5 m depth) were used to assess the actual sediment transport patterns over a 2-month period. Third, a remote-sensing technique for the identification of fetch distance, a saltation impact sensor (Safire) and wind data were utilized to gauge, qualitatively, sediment transport patterns over a 1-month period. Secondary airflow effects were found to play a major role in the sediment flux patterns at these timescales, with measured and predicted rates matching closely during the trench trap study. The results suggest that fetch distance is an unimportant variable at this site. Copyright © 2007 John Wiley & Sons, Ltd. [source]


    An examination of employment change in Northern Ireland's environmental industry, 1993,2003

    ENVIRONMENTAL POLICY AND GOVERNANCE, Issue 4 2001
    David Eastwood
    An examination of employment change based upon an exploratory classification of Northern Ireland's environmental industry is undertaken. Results show that, in 1993, some 12,900 persons or around 2.1% of the total civilian employment in the region were working in a ,green production sector'. By using a range of data sources it is suggested that significant opportunities for employment expansion currently exist. Indeed, a total of between 4000 and 6000 new environmental jobs could be created in Northern Ireland by the year 2003. Most of the growth is anticipated in the traditional areas of recycling and re-use, pollution treatment and control and energy conservation. In a small and peripheral European economy these figures have important implications for the development of the local labour market. To this end, a series of recommendations is put forward that could help Northern Ireland maximize the employment potentials offered by these types of environmental activity.

    How Effective is Farmer Early Retirement Policy?

    EUROCHOICES, Issue 3 2008
    Quelle est l'efficacité de la politique de préretraite pour les agriculteurs?
    Summary How Effective is Farmer Early Retirement Policy? Financial support for EU farmers seeking early retirement is a discretionary element of CAP rural development policy and some EU member states, most notably France, Ireland and Greece have chosen to implement the measure. We explore whether the introduction of such schemes is likely to represent good value for money. We use data from Northern Ireland, a region with a relatively small-scale family-farm structure, where there have been periodic calls from farmer groups to introduce support for early retirement. We estimate the benefits that might arise from the introduction of such a scheme using FADN data and a separate survey of 350 farmers aged 50 to 65. We find that farm scale is a significant determinant of profit per hectare but that operator age is not. Benefits from releasing land through an early retirement scheme are conditional on such transfers bringing about significant farm expansion and changes in land use. Even when these conditions are satisfied, however, pensions payments of only about one-third the statutory maximum could be justified in a best-case scenario. Almost a quarter of all payments would incur deadweight losses, i.e., go to farmers who would be retiring anyway. Overall, the economic case for such a scheme is considered to be weak. Le soutien financier aux agriculteurs de l'Union européenne qui veulent prendre une retraite anticipée est un élément discrétionnaire de la politique de développement rural de la PAC et certains pays membres, en tout premier lieu la France, l'Irlande et la Grèce, ont choisi de mettre en place cette mesure. Nous recherchons si l'introduction de telles mesures serait intéressante par rapport au coût financier. L'analyse porte sur des données nord-irlandaises, région d'exploitations familiales de taille relativement petite dans laquelle les représentants agricoles ont régulièrement appeléà la mise en place de soutien pour la retraite anticipée. Nous estimons les avantages que pourrait procurer l'introduction de cette mesure à l'aide de données du RICA et d'une enquête indépendante portant sur 350 agriculteurs âgés de 50 à 65 ans. Nous trouvons que la taille de l'exploitation est un déterminant significatif du profit par hectare mais que l'âge de l'exploitant n'en est pas un. Les avantages de la mise à disposition de terres grâce à un programme de préretraite dépendent de la capacité de ces transferts à entraîner un accroissement notable de la taille des exploitations et des modifications de l'utilisation des terres. Cependant, même lorsque ces conditions sont remplies, seuls des paiements représentant un tiers du niveau maximum prévu dans le programme de préretraite pourraient se justifier dans un scénario optimal. Pratiquement un quart du total des paiements serait liéà des pertes de bien-être, c'est-à-dire que les bénéficiaires seraient des agriculteurs qui aurait pris leur retraite de toute façon. Globalement, l'intérêt économique d'un tel programme est considéré comme faible. Die finanzielle Unterstützung von Landwirten in der EU, die in den Vorruhestand gehen möchten, stellt in der Politik der GAP zur Entwicklung des ländlichen Raums ein diskretionäres Element dar; in einigen Mitgliedsstaaten wie z.B. Frankreich, Irland und Griechenland wird diese Maßnahme angeboten. Wir untersuchen, ob es möglicherweise finanziell sinnvoll wäre, solche Programme einzuführen. Dazu ziehen wir Daten aus Nordirland heran, einer Region mit relativ kleinen landwirtschaftlichen Familienbetrieben, in der sich Landwirte regelmäßig dafür aussprechen, Vorruhestandprogramme einzuführen. Wir schätzen den Nutzen, der sich aus der Einführung eines solchen Programms ergeben könnte, anhand von INLB-Daten und einer gesonderten Befragung von 350 Landwirten im Alter von 50 bis 65 Jahren. Wir stellen fest, dass es sich bei der Betriebsgröße , im Gegensatz zum Alter des Betreibers , um einen entscheidenden Faktor für die Höhe des Gewinns pro Hektar handelt. Ein Nutzen aus der Landübertragung aufgrund eines Vorruhestandprogramms beruht auf solchen Transfers, die eine bedeutsame Betriebserweiterung und veränderte Flächennutzung zur Folge haben. Selbst wenn diese Bedingungen erfüllt werden, könnten günstigstenfalls nur Rentenzahlungen in Höhe von etwa einem Drittel der gesetzlich verankerten Höchstsumme gerechtfertigt werden. Beinahe ein Viertel aller Zahlungen wäre mit Mitnahmeeffekten verbunden, d.h. Landwirten zukommen, die ohnehin den Ruhestand antreten würden. Aus ökonomischer Sicht muss ein solches Programm als schwach eingestuft werden. [source]


    Cancer patients' satisfaction with communication, information and quality of care in a UK region

    EUROPEAN JOURNAL OF CANCER CARE, Issue 1 2005
    R. DAVIDSON bsc, abps. consultant clinical psychologist , dphil., msc (clin. psych.)
    Effective patient,professional communication can be of crucial importance to long-term psycho-social outcomes in patients with cancer. This study identifies patient satisfaction with regard to various aspects of communication and perceived quality of care. A well-validated questionnaire was administered to 435 cancer patients throughout Northern Ireland during a 3-month period. Northern Ireland can be regarded as a typical UK region in terms of cancer service configuration. The cohort consisted of patients with breast, colorectal, lung, prostate, gynaecological and gastric cancers. There was a 78% response rate. Satisfaction scores were individually calculated for various aspects of care, particularly diagnosis, treatment, follow-up and overall care. Non-parametric analysis examined the interaction between satisfaction scores and primary tumour site, age and gender. While overall satisfaction scores were relatively high, there was considerable variation. Of particular note was the interaction between perceived satisfaction and quality of care, communication, tumour site and age. Key findings are that there are a number of issues with regard to information and communication which can be clearly improved within Northern Ireland cancer services. The paper concludes that patient,professional communication should be tailored to meet individual need. [source]


    Estimation of the phosphorus sorption capacity of acidic soils in Ireland

    EUROPEAN JOURNAL OF SOIL SCIENCE, Issue 3 2001
    R. O. Maguire
    Summary The test for the degree of phosphorus (P) saturation (DPS) of soils is used in northwest Europe to estimate the potential of P loss from soil to water. It expresses the historic sorption of P by soil as a percentage of the soil's P sorption capacity (PSC), which is taken to be , (Alox + Feox), where Alox and Feox are the amounts of aluminium and iron extracted by a single extraction of oxalate. All quantities are measured as mmol kg soil,1, and a value of 0.5 is commonly used for the scaling factor , in this equation. Historic or previously sorbed P is taken to be the quantity of P extracted by oxalate (Pox) so that DPS = Pox/PSC. The relation between PSC and Alox, Feox and Pox was determined for 37 soil samples from Northern Ireland with relatively large clay and organic matter contents. Sorption of P, measured over 252 days, was strongly correlated with the amounts of Alox and Feox extracted, but there was also a negative correlation with Pox. When PSC was calculated as the sum of the measured sorption after 252 days and Pox, the multiple regression of PSC on Alox and Feox gave the equation PSC = 36.6 + 0.61 Alox+,0.31 Feox with a coefficient of determination (R2) of 0.92. The regression intercept of 36.6 was significantly greater than zero. The 95% confidence limits for the regression coefficients of Alox and Feox did not overlap, indicating a significantly larger regression coefficient of P sorption on Alox than on Feox. When loss on ignition was employed as an additional variable in the multiple regression of PSC on Alox and Feox, it was positively correlated with PSC. Although the regression coefficient for loss on ignition was statistically significant (P <,0.001), the impact of this variable was small as its inclusion in the multiple regression increased R2 by only 0.028. Values of P sorption measured over 252 days were on average 2.75 (range 2.0,3.8) times greater than an overnight index of P sorption. Measures of DPS were less well correlated with water-soluble P than either the Olsen or Morgan tests for P in soil. [source]


    Conflict and Rationality: Accounting in Northern Ireland's Devolved Assembly

    FINANCIAL ACCOUNTABILITY & MANAGEMENT, Issue 1 2005
    Mahmoud Ezzamel
    The purpose of this study is to explore the implications of the rationality of accounting thought and practice as a mediating mechanism in the highly-charged, conflict-ridden situation in Northern Ireland (NI). The paper draws on a variety of data sources, including a series of interviews with key actors. There are some indications of accounting information being used to inform discussion and debate at the new Assembly. However, a number of politicians, from a spectrum of political traditions, do not relate to this new language, and the instability of the process (evidenced by frequent suspensions) discourages learning and engagement. Overall, this suggests that, without greater continuity, there is a limitation on the ability of accounting practices to mediate tensions. [source]


    A comparison of catchment based salmonid habitat survey techniques in three river systems in Northern Ireland

    FISHERIES MANAGEMENT & ECOLOGY, Issue 3 2002
    W. C. K. O'CONNOR
    Three survey techniques, a fully quantitative, multivariate study; a shorter or truncated fully quantitative method and a Geographical Information System (GIS) based, semi-quantitative, survey technique, were developed to assess in-river salmonid habitats on a catchment wide basis. These methods were tested and compared on three river systems in Northern Ireland: the Blackwater, the Bush and the Main. The research indicated that the fully quantitative method generated an accurate habitat database but required a high investment in time and resources to complete. The truncated survey approach often produced an inaccurate habitat database. The semi-quantitative technique generated a more accurate habitat dataset with greater productivity and efficiency for the resources invested in the survey. [source]


    Problem Representation and Conflict Dynamics in the Middle East and Northern Ireland

    FOREIGN POLICY ANALYSIS, Issue 3 2005
    Donald A. Sylvan
    In an effort to explain conflictual and cooperative actions in the Middle East and Northern Ireland at a time (1995,1999) when international structural factors were relatively constant, this article focuses on cognitive factors. Specifically, statements of leaders representing multiple actors in the Israeli,Palestinian and Northern Ireland relationship are examined. Texts from these leaders serve as data for the independent variable, problem representation. Hypotheses argue that the existence and centrality of actor problem representations can help explain behavior, in a manner that adds to more widely used scholarly explanations. More specifically, the article explores the relationship among leaders' "problem representations" and conflict between the entities they lead. Problem representation is measured in three dimensions using Foreign Broadcast Information Service (World News Connection) texts: (1) centrality of enemy image, (2) how inclusive/exclusive the leader is in describing the in-group and principal outgroup, and (3) the key definition of the problem (coded in terms of three strategies: justice, governance, or threat). Conflict, the dependent variable, is measured in terms of KEDS-TABARI event data on deeds (not words) in the Israeli,Palestinian and Northern Ireland conflicts. Strikingly, the analysis finds that Israeli actions are strongly related to prior and current Palestinian leaders' problem representations, much more than they are to Israeli leaders' problem representations. Similarly, Palestinian actions are found to have a clear relationship with prior and current Israeli leaders' problem representations, much more than they are with Palestinian leaders' problem representations. These results are particularly strong when the problem representation is one of the overall political leadership on the "other" side. Additionally, in-group and out-group inclusivity are the most significant predictors of actions. For Northern Ireland, the same two themes prevail, although not as strongly: there is a clear statistical relationship between each side's problem representations and the other side's actions, stronger in fact than the relationship between their own side's representations and actions. Also, in-group and out-group inclusivity produce a strong statistical relationship with conflict and cooperation. Finally, results are compared with a "tit-for-tat" hypothesis, and found to embellish that hypothesis. [source]


    An application of canonical correspondence analysis for developing ecological quality assessment metrics for river macrophytes

    FRESHWATER BIOLOGY, Issue 5 2005
    IAN DODKINS
    Summary 1. Aquatic macrophyte composition and abundance is required by the European Union's Water Framework Directive for determining ecological status. Five metrics were produced that can be combined to determine the deviation of aquatic macrophytes from reference conditions in Northern Ireland's rivers. 2. Species optima and niche breadths along silt, nitrate, pH, conductivity and dissolved oxygen gradients were generated from aquatic macrophyte and water quality surveys conducted at 273 sites throughout Northern Ireland using Canonical Correspondence Analysis (CCA). Five metric scores based on these environmental gradients were determined at new monitoring sites using the mean optima of the species occurring at the site, weighted by percentage cover and niche breadth of each species. 3. A preliminary reference network of 32 sites of high physico-chemical and hydromorphological quality, and representative of the range of river types in Northern Ireland, enabled reference metric scores to be produced for each river type. Five unimpacted and twenty impacted sites were used for testing the performance of the metrics. By subtracting reference metric scores from metric scores at a monitoring site measures of ecological impact could be determined along five different impact gradients. Metrics were also combined to give a measure of total ecological change. 4. The metrics system distinguished unimpacted from impacted sites and correctly identified 77% of the known impacts. The metrics distinguished different types of impact, e.g. silt and nitrate. 5. Aquatic macrophyte occurrence and abundance has high natural variability at a site, both temporally and spatially. This method was designed to be sensitive to ecological change whilst reducing noise caused by natural variation. [source]


    Post-excavation deterioration of the Copney Bronze Age Stone Circle Complex: A geomorphological perspective

    GEOARCHAEOLOGY: AN INTERNATIONAL JOURNAL, Issue 5 2010
    Patricia A. Warke
    Post-excavation deterioration of stones from under blanket peat at the Copney Bronze Age Stone Circle Complex in County Tyrone, Northern Ireland, proceeded through widespread scaling, flaking, and splitting of stones. Investigation showed that prior to burial the porphyritic stones already possessed a complex legacy of geological weaknesses derived from hydrothermal alteration and tectonic deformation. Analysis indicated that significant alteration occurred during approximately 2000 years of burial under acidic peat cover, with development of a secondary porosity, alteration of primary minerals, and the opening of preexisting lines of weakness within the stones. Burial under peat also resulted in "bleaching" the stones so that they appeared white in color following excavation. These alterations during burial left the stones in a significantly weakened state and particularly susceptible to the effects of subaerial weathering processes. Data underline the potential fragility of excavated stonework and highlight the need to plan for its aftercare before complete excavation is undertaken. © 2010 Wiley Periodicals, Inc. [source]


    Mineral chemical provenance of Neolithic pitchstone artefacts from Ballygalley, County Antrim, Northern Ireland

    GEOARCHAEOLOGY: AN INTERNATIONAL JOURNAL, Issue 3 2002
    Jeremy Preston
    A large number of pitchstone fragments and artefacts have recently been discovered at a Neolithic settlement site in Ballygalley, Co. Antrim, Northern Ireland. They consist predominantly of flakes and un-reworked lumps and cores, with only one complete tool being found. Since no sources of workable pitchstone exist in Ireland, the source must have been the abundant pitchstone volcanic rocks found on the Hebridean Islands of northwest Scotland. The composition of the glass from a number of artefacts is highly siliceous, indicating that they were derived from pitchstones on the Island of Arran; pitchstones from all other Scottish locations are less silica-rich. In addition, analysis of pyroxene and amphibole microcrystallites within the pitchstone suggests that the Corriegills area of Arran is the most likely source of the Ballygalley artefacts, although the precise outcrop has proved elusive. These finds, and others across Ireland, show that raw materials were being transported and probably traded over considerable distances despite there being suitable alternative sources of material for making tools (flint, etc.) available in the local area. This suggests that the pitchstone had a very specialist use. © 2002 Wiley Periodicals, Inc. [source]


    The End of Violence and Introduction of ,Real' Politics: Tensions in Peaceful Northern Ireland

    GEOGRAFISKA ANNALER SERIES B: HUMAN GEOGRAPHY, Issue 3 2001
    Arponen, Kaisa Kuusisto
    This article discusses contemporary developments in the Northern Ireland peace process, and pays particular attention to some of the main paths away from political violence towards ,real' politics. Even the peace process has left many tensions in Northern Ireland. The article focuses on the gap between formal governing or decision,making and everyday life in localities, and the role of geographical scales in the peace initiatives is touched upon. In particular, the Belfast Agreement and its effects on localities are assessed to illustrate some of the advances and drawbacks of the multi,level peace developments. By looking at the local context of Derry/Londonderry, this study shows how ambiguous the very existence of peace is in Northern Ireland: for international media there is peace in Northern Ireland, for local politicians ,yes, maybe', but for many locals ,no'. In the localities territoriality, secured boundaries and collective identities remain crucial elements of everyday life. [source]


    Fluid evolution in base-metal sulphide mineral deposits in the metamorphic basement rocks of southwest Scotland and Northern Ireland

    GEOLOGICAL JOURNAL, Issue 1 2005
    Martin Baron
    Abstract The Dalradian and Ordovician,Silurian metamorphic basement rocks of southwest Scotland and Northern Ireland host a number of base-metal sulphide-bearing vein deposits associated with kilometre-scale fracture systems. Fluid inclusion microthermometric analysis reveals two distinct fluid types are present at more than half of these deposits. The first is an H2O,CO2,salt fluid, which was probably derived from devolatilization reactions during Caledonian metamorphism. This stage of mineralization in Dalradian rocks was associated with base-metal deposition and occurred at temperatures between 220 and 360°C and pressures of between 1.6 and 1.9,kbar. Caledonian mineralization in Ordovician,Silurian metamorphic rocks occurred at temperatures between 300 and 360°C and pressures between 0.6 and 1.9,kbar. A later, probably Carboniferous, stage of mineralization was associated with base-metal sulphide deposition and involved a low to moderate temperature (Th 70 to 240°C), low to moderate salinity (0 to 20,wt% NaCl eq.), H2O,salt fluid. The presence of both fluids at many of the deposits shows that the fractures hosting the deposits acted as long-term controls for fluid migration and the location of Caledonian metalliferous fluids as well as Carboniferous metalliferous fluids.

    ABSTRACT Aim, The study examined qualitative predictions of ecological theories in relation to the spatial distribution of species turnover of aquatic macrophytes, through the following parameters: (1) distance between lakes (2) chemical conditions of the lakes (3) chemical differences between the lakes, and (4) the lake size. Location, 562 lakes dispersed throughout Northern Ireland were analysed. Methods, To obtain species turnover estimates independent of richness, the average distance between focal lakes and their five nearest neighbours in ordination space (DCA) was standardized by the species richness in a Generalized Additive Model (GAM). The relationships between species turnover and ecological (chemical condition, chemical difference, distance between lakes, and lake-size) and geographical parameters (latitude, longitude, and altitude) were analysed using GAM. Results, The results indicate that the pattern in species turnover is a combination of the chemical conditions and the distance between the lakes, including the interaction term. The effects of chemical heterogeneity and lake size parameters were both positive but weak. In general, increased distance and decreased ionic concentration contribute to increased turnover. The influence of distance on species turnover is strongest at low and high altitude, and at mid-elevation the species turnover is mainly driven by the chemical conditions. Towards the north there is an increasing influence of distance, whereas in the south the chemical conditions have their strongest influence. Conclusions, There is a need for components from several established ecological theories to explain the spatial trends in species turnover within Northern Ireland. Central theories in this particular study are the population/metapopulation dynamics, the continuum concept, and the species-pool concept. [source]


    Effects of drought on contrasting insect and plant species in the UK in the mid-1990s

    Abstract Aim We examined the effects of drought in the summer of 1995 and the subsequent year on contrasting species of plants, moths, butterflies and ground beetles. We tested whether population increases were associated with: (a) species of warm environments (b) species of dry environments (c) species with rapid reproduction (d) species with high rates of dispersal. Location The study was conducted at Environmental Change Network (ECN) sites throughout Great Britain and Northern Ireland. Methods Climate monitoring, recording of plant species in permanent plots, transect walking for butterflies, light trapping for moths and pitfall trapping for carabid beetles were used. Results There was an overall increase in the number of species recorded in permanent vegetation plots between 1994 and 1996, principally among the annual and biennial vascular plants, probably as a result of gap colonization in grasslands. Most butterfly and moth species increased between 1994 and 1995. Among the butterflies, a southern distribution and high mobility were associated with species tending to increase throughout the period 1994,96, whereas declining species tended to have a northern distribution. A similar number of carabid beetle species increased as decreased in the period 1994,96; decreasing species tended to be associated with lower temperatures and wetter soils. Conclusions Current climate change scenarios indicate that the incidence of droughts in the United Kingdom will increase. A series of dry, hot summers could lead to a rapid change in the population of some species although others, including many plants, may be more resilient. This may lead to complex changes in ecosystems and needs to be considered in planning conservation strategies. [source]


    Governance and Democracy in Northern Ireland: The Role of the Voluntary and Community Sector after the Agreement

    GOVERNANCE, Issue 3 2001
    Cathal McCall
    Since 1998, Northern Ireland has been the subject of a unique experiment in governance and democracy. The experiment includes the establishment of a participatory Civic Forum in which the voluntary and community sector has an important stake. Beginning with a discussion of the merits of a participatory aspect to democracy in the contemporary age, this paper identifies factors that might help establish the Civic Forum as a successful participatory institution in Northern Ireland. Key factors include the attitude towards the Forum of political representatives and their willingness to foster a participatory dimension to the new democracy. Other important factors are inclusiveness and the balance of sectoral representation in the Forum. [source]


    Consociational Theory, Northern Ireland's Conflict, and its Agreement.

    GOVERNMENT AND OPPOSITION, Issue 1 2006
    Part 1:, What Consociationalists Can Learn from Northern Ireland
    In the first of two articles the authors show what consociational theory may learn from the case of Northern Ireland, namely, the importance of external agencies in making and implementing consociational settlements, the relations between consociational and self-determination settlements, the ,complexity' of internal settlements, the merits of STV (PR) in electoral arrangements, innovations in using proportional representation decision rules to allocate ministerial portfolios, and conceptual modifications. A second article addresses what anti-consociationalists may learn from the same case. [source]


    Older people , recipients but also providers of informal care: an analysis among community samples in the Republic of Ireland and Northern Ireland

    Abstract Data on both the provision and receipt of informal care among populations of older adults are limited. Patterns of both informal care provided and received by older adults in the Republic of Ireland (RoI) and Northern Ireland (NI) were evaluated. A cross-sectional community-based population survey was conducted. Randomly selected older people (aged 65+, n = 2033, mean age (standard deviation): 74.1 years (6.8), 43% men, 68% response rate) provided information on the provision and receipt of care, its location, and the person(s) who provided the care. Twelve per cent of the sample (251/2033) identified themselves as informal caregivers (8% RoI and 17% NI). Caregivers were more likely to be women, married, have less education and have less functional impairment. Forty-nine per cent (1033/2033, 49% RoI and 48% NI) reported receiving some form of care in the past year. Care recipients were more likely to be older, married, have more functional impairment, and poorer self-rated health. Receiving regular informal care (help at least once a week) from a non-resident relative was the most common form of help received [28% overall (578/2033); 27% RoI and 30% NI]. Five per cent (n = 102/2033) of the sample reported both providing and receiving informal care. Levels of informal care provided by community-dwelling older adults were notably higher than reported in single-item national census questions. The balance of formal and informal health and social care will become increasingly important as populations age. It is essential, therefore, to evaluate factors facilitating or impeding informal care delivery. [source]


    Primary care in the UK: understanding the dynamics of devolution

    HEALTH & SOCIAL CARE IN THE COMMUNITY, Issue 5 2001
    Mark Exworthy
    Abstract The United Kingdom is ostensibly one country and yet public policy often varies between its constituent territories , England, Scotland, Wales and Northern Ireland. Health policy illustrates the dilemmas inherent in an apparently unitary system that permits scope for territorial variation. Administrative devolution has now been accompanied by political devolution but their interaction has yet to produce policy outcomes. This paper describes recent health policy reform with regard to primary care in terms of the tension inherent in current policy between notions of a ,one nation NHS' and the territorial diversity wrought by devolution. The paper provides a framework for understanding the emergent outcomes by exploring various concepts. In particular, the existing character of territorial policy networks, the properties of policies in devolved territories and intergovernmental relations are considered from various disciplines to examine whether greater diversity or uniformity will result from the dual reform process. Whilst this evaluation can, at this stage, only be preliminary, the paper provides a framework to appraise the emerging impact of devolution upon primary care in the UK. [source]

    Equality in Higher Education in Northern Ireland

    HIGHER EDUCATION QUARTERLY, Issue 2 2005
    R.D. Osborne
    The higher education sector in Northern Ireland has been fully involved in the public policies designed to enhance equality. Starting with measures designed to secure greater employment between Catholics and Protestants, known as fair employment, the policies are now designed to promote equality of opportunity across nine designated groups together with the promotion of ,good relations' on the grounds of religion and race. The paper examines the implementation of this new policy framework in the universities and suggests that progress to date has been fairly limited. [source]
