Assessing the sensitivity of seabed species and biotopes - the Marine Life Information Network (MarLIN).

Science-based approaches to support the conservation of marine biodiversity have been developed in recent years. They include measures of ‘rarity’, ‘diversity’, ‘importance’, biological indicators of water ‘quality’ and measures of ‘sensitivity’. Identifying the sensitivity of species and biotopes, the main topic of this contribution, relies on accessing and interpreting available scientific data in a structured way and then making use of information technology to disseminate suitably presented information to decision makers. The Marine Life Information Network (MarLIN) has achieved that research for a range of environmentally critical species and biotopes over the past four years and has published the reviews on the MarLIN Web site (www.marlin.ac.uk). Now, by linking the sensitivity database and databases of survey information, sensitivity mapping approaches using GIS are being developed. The methods used to assess sensitivity are described and the approach is advocated for wider application in Europe.

Making the law accessible to non-lawyers: effects of different kinds of expertise on perceived usability of online legal information services

To help design an environment in which professionals without legal training can make effective use of public sector legal information on planning and the environment - for Add-Wijzer, a European e-government project - we evaluated their perceptions of usefulness and usability. In concurrent think-aloud usability tests, lawyers and non-lawyers carried out information retrieval tasks on a range of online legal databases. We found that non-lawyers reported twice as many difficulties as those with legal training (p = 0.001), that the number of difficulties and the choice of database affected successful completion, and that the non-lawyers had surprisingly few problems understanding legal terminology. Instead, they had more problems understanding the syntactical structure of legal documents and collections. The results support the constraint attunement hypothesis (CAH) of the effects of expertise on information retrieval, with implications for the design of systems to support the effective understanding and use of information.

Effect of cultivar and storage time on the volatile flavor components of baked potato

Tubers of five cultivars of potato were stored at 4 degreesC for 2 3 and 8 months and baked in a conventional oven The flavor compounds from the baked potato flesh were isolated by headspace adsorption onto Tenax and analyzed by gas chromatography-mass spectrometry On a quantitative basis compounds derived from lipid and Maillard reaction/sugar degradation dominated the flavor isolates with sulfur compounds, methoxypyrazines, and terpenes making smaller contributions Levels of 37 of the > 150 detected compounds were monitored in each cultivar with time of storage Many significant differences were found in levels of individual compounds compound classes and total monitored compounds for the individual effects of cultivar and storage time and for their two way interaction Differences may be explained by variations in levels of flavor precursors and activities of enzymes mediating flavor compound formation among cultivars and storage times In addition differences in agronomic conditions may partly account for variations among cultivars Overall of the compounds monitored those most likely having the greatest flavor impact were 2-isopropyl 3 methyoxypyrazine 2 isobutyl 3-methoxypyrazine dimethyl trisulfide, decanal and 3 methylbutanal, with methylpropanal, 2 methylbutanal methional, and nonanal also being probable important contributors to flavor.

Explicit argumentation as a supervisory tool for decision making in child protection cases involving human rights issues

This paper addresses the problems often faced by social workers and their supervisors in decision making where human rights considerations and child protection concerns collide. High profile court cases in the United Kingdom and Europe have consistently called for social workers to convey more clarity when justifying their reasons for interfering with human rights in child protection cases. The themes emerging from these case law decisions imply that social workers need to be better at giving reasons and evidence in more explicit ways to support any actions they propose which cause interference with Convention Rights. Toulmin (1958, 1985) offers a structured approach to argumentation which may have relevance to the supervision of child protection cases when social workers and managers are required to balance these human rights considerations. One of the key challenges in this balancing act is the need for decision makers to feel confident that any interventions resulting in the interference of human rights are both justified and proportionate. Toulmin’s work has already been shown to have relevance for assisting social workers navigate pathways through cases involving competing ethical and moral demands (Osmo and Landau, 2001) and more recently to human rights and decision making in child protection (Duffy et al, 2006). Toulmin’s model takes the practitioner through a series of stages where any argument or proposed recommendation (claim) is subjected to intense critical analysis involving exposition of its strengths and weaknesses. The author therefore proposes that explicit argumentation (Osmo and Landau, 2001) may help supervisors and practitioners towards safer and more confident decision making in child protection cases involving the interference of the human rights of children and parents. In addition to highlighting the broader context of human rights currently permeating child protection decision making, the paper will include case material to practically demonstrate the application of Toulmin’s model of argumentation to the supervision context. In this way the paper adopts a strong practice approach in helping to assist practitioners with the problems and dilemmas they may come up against in decision making in complex cases.

The perspectives of young children in care about their circumstances and implications for social work practice

Recent reviews of research regarding children in care have concluded that there remains little research which specifically focuses on young children. This paper presents the findings of research carried out with a sample of young children in care (aged 4-7 years) regarding their perspectives of their circumstances. The findings reveal that they have deeply held views regarding living with risk; removal from their families; unresolved feelings of guilt and loss; and not being listened to. This paper considers the implications of these findings for social work practice. It concludes by stressing the capacity of young children in care to express their perspectives, and the importance of practitioners seeking these views and incorporating them into assessment and decision-making processes.

ASSESSMENTS AND DECISIONS IN METELLINA-SEGMENTATA (ARANEAE, METIDAE) - EVIDENCE OF A PHEROMONE INVOLVED IN MATE GUARDING

Assessments and decision-making underlying the initiation of mate guarding in a common web-building spider, Metellina segmentata, are examined in a series of field and laboratory studies. Adult males do not build webs but wander in search of females and mating opportunities. Adult males then wait at the edge of the webs of females and guard them prior to courtship and mating. Guarded females were heavier, larger and carried more mature eggs than solitary females. An active process of information gathering is apparent from introductions of males to the webs of females. Males make accurate assessments about female quality, even in the absence of the resident female. Cues involving web architecture are not used. Males may assess pheromonal cues on the web of the female in deciding whether to guard or abandon a female.

A Review of the Research on Offender Supervision in the Republic of Ireland and Northern Ireland

This paper reviews existing research on offender supervision in the Republic of Ireland and Northern Ireland. Three distinct areas are considered: practising offender supervision, experiencing supervision and decision-making in this sphere. The material presented draws on findings from a European-wide research action under the Cooperation in Science and Technology (COST) initiative. The review highlights some of the gaps in knowledge and the need to focus research attention in this area. This need is underlined by the expansion in probation’s role, both North and South. In common with other countries there has been a growth in referrals to probation and in the numbers of people subject to supervision, whether on a community sentence or under post-custodial licence conditions. This review highlights some of the relevant factors including the increased emphasis placed on public protection and attempts to reduce the prison population. The circulation of people through systems and the experiences, processes and decision-making involved are all areas that we argue are worthy of further research attention.

Assessing suspended sediment dynamics in relation to ecological thresholds and sampling strategies in two Irish headwater catchments

Prediction of the impact of suspended sediment on aquatic ecosystems requires adequate knowledge of sediment dynamics in surface waters. Often, studies reporting the response of aquatic biota to suspended sediment are concerned with concentrations, while catchment erosion studies often report sediment delivery as annual loads and yields, making the comparison to documented ecological impacts difficult. Similarly, the European Union Freshwater Fish Directive (FFD) (78/659/EC) stipulates a guideline value of 25mgl which should not be exceeded, with the exception of floods and droughts. In this respect, the significance of suspended sediment in two Irish rivers was assessed using turbidity sensors calibrated for suspended sediment. Sediment yields of 0.07 tonnes (t) hayear and 0.44thayear and annual FFD exceedance frequency of 8.3% and 17.8% were estimated for the two catchments. Contrasts in the frequency of exceedance events between both catchments was observed, yet duration was typically short (

The Art of Refusal: The Experiences of Grant Makers and Grant Seekers

This research project explores the communications’ experiences and practices of
selected grant making and grant seeking organisations, at the point of grant refusal. It was funded by the Charities Aid Foundation, and undertaken through collaboration with the Association of Charitable Foundations (ACF).
The research context is the enhanced competition for funding in which many grant seeking organisations experience the disappointment of refusal; whilst grant makers also face multiple pressures, in responding to grant seekers’ needs. This is an operating environment in which subsequent organisational learning appears demanding.
The aims of the research were to:
- Increase understanding of the communications demands, challenges and
opportunities in giving, receiving and sharing news of grant refusal
- Identify opportunities for organisational learning in these situations, for grant
makers and grant seekers
- Contribute to future practice improvement and development, by drawing on
the reported experiences and practices of participating respondents.

The research focuses on private, formal grant makers (foundations and trusts); and their grant seeking organisational constituencies. It excludes study of public grant makers’ grant refusal processes and those of individuals making personal gifts, direct businesses’ grant making, and grant making by community foundations and by other operating and fundraising charities. A staged research process began in 2008, and field research completed in 2009/2011.

Community Arts and Appropriate Internet Technology: Participation, Materiality, and the Ethics of Sustainability in the Digitally Networked Era

This thesis establishes appropriate internet technology as a matter of sustainability for the community arts field. It begins with a contextual review that historicises community art in relation to technological, cultural, and political change. It goes on to identify key challenges for the field resulting from the emerging socio-cultural significance of the internet and digital media technologies. A conceptual review of the literature positions these issues in relation to Internet Studies, integrating key concepts from Software Studies and the computational turn with approaches from the fields of ICT for Development (ICT4D), Critical Design, and Critical Making. Grounded in these intersecting literatures the thesis offers a new pragmatic ethics of appropriate internet technology: one involving an alternative philosophical platform from which suitable internet-based technologies can be designed and assembled by practitioners. I interrogate these ideas through an in-depth investigation of CuriousWorks, an Australian community arts organisation, focusing on their current internet practices. The thesis then reflects on some experimental interventions I designed as part of the study for the purpose of provoking shifts in the field of community arts. The research findings form the foundation of a series of recommendations offered to practitioners and policy makers that may guide their critical and creative uses of internet technologies in the future.

Women’s Perceptions and Experiences of Fetal Macrosomia

Objective
to explore women's perceptions and experiences of pregnancy and childbirth following birth of a macrosomic infant (birth weight ≥4000 g).

Methods
a qualitative design utilising interviews conducted 13–19 weeks post partum in women's homes. The study was conducted in one Health and Social Care Trust in Northern Ireland between January and September 2010. Participants were identified from a larger cohort of women recruited to a prospective study exploring the impact of physical activity and nutrition on macrosomia. Eleven women who delivered macrosomic infants participated in this phase of the study.

Findings
four overarching themes emerged: preparation for delivery; physical and emotional impact of macrosomia; professional relations and perceptions of macrosomia. Findings highlighted the importance of communication with health professionals in relation to both prediction of macrosomia and decision making about childbirth, and offers further understanding into the physical and emotional impact of having a macrosomic infant on women. Furthermore, there was evidence that beliefs and perceptions relating to macrosomia may influence birth experiences and uptake of health promotion messages.

Key conclusions and implications for practice
this study provides important insight into women's experiences of macrosomia throughout the perinatal period and how they were influenced by previous birth experiences, professional relations and personal perceptions and beliefs about macrosomia. Pregnant women at risk of having a macrosomic infant may require extra support throughout the antenatal period continuing into the postnatal period. Support needs to be tailored to the woman's information needs, with time allocated to explore previous birth experiences, beliefs about macrosomia and options for childbirth.

Framed Memories of Berlin:Film, Remembrance and Architecture

In The City of Collective Memory, urban historian Christina Boyer (1994) defines the image of a city as an abstracted concept, an imaginary (re)constructed form. This urban image is created from many aspects, one of which is the framed and edited views and experiences found in films situated in or about a particular city. In this study, to explore the collective memory of the city of Berlin from an architectural point of view, one film from each of the major historical periods of Berlin since the invention of cinema is examined: pre-WWI, interwar period, the Nazi period, post-WWII, Berlin Wall/Cold War, and the reunification period. Memory-making in the city is studied following the footsteps of the protagonists in the films, concluding that film-making and memory-making make use of similar processes, the editing of fragmented pieces of so-called reality, to create its own reality.

Child Maltreatment and High Risk Families: Protecting children and young people

Most child maltreatment occurs within the context of high risk families. There are ethical, economic and ecological reasons why physical abuse in such families should be a major concern. Physical abuse is a significant issue throughout the UK. Yet, while neglect and other forms of abuse are receiving focused attention, physical abuse may languish under the misconceptions that it is no longer a problem, is addressed elsewhere, or is just too overwhelming an issue.
The physical abuse of children can involve regular, violent treatment at the hands of parents or carers over a number of years. Its physical effects may last for days and may result in actual physical injury. It is not accidental. Although physical abuse can occur in any family, it is prevalent in particular sectors of society, where families may be vulnerable to a combination of complex risk factors such as domestic abuse, alcohol and drug (mis)use, and mental health issues. These factors are present in 34% of Serious Case Reviews (SCRs).
The authors provide an increased understanding of risk, analysis, impact, learning and the current landscape of service delivery in relation to the physical abuse of children living in high risk families for professional, postgraduate and policy-making audiences.
