The ocean sunfish Mola mola: insights into distribution, abundance and behaviour in the Irish and Celtic Seas

Here we provide baseline data on the distribution and abundance of Mola mola within the Irish and Celtic Seas, made during aerial surveys from June to October during 2003-2005. These data were considered in conjunction with concurrent observations of three potential jellyfish prey species found throughout the region: Rhizostoma octopus, Chrysaora hysoscella and Cyanea capillata. A total area of 7850 km(2) was surveyed over the three years with an observed abundance of 68 sunfish giving a density of 0.98 ind/100 km(2). Although modest, these findings highlight that the species is more common than once thought around Britain and Ireland and an order of magnitude greater than the other apex jellyfish predator found in the region, the leatherback turtle (Dermochelys coriacea). furthermore, the distribution of sunfish sightings was inconsistent with the extensive aggregations of Rhizostoma octopus found throughout the study area. The modelled distributions of predator-prey co-occurrence (using data for all three jellyfish species) was less than the observed co-occurrence with the implication that neither jellyfish nor sunfish were randomly distributed but co-occurred more in the same areas than expected by chance. Finally, observed sunfish were typically small (similar to 1 in or less) and seen to either bask or actively swim at the surface.

Pitfalls in Strategic Planning: Lessons for Legitimacy

The paper considers how planning as a political activity is underpinned by concepts of justice and how professional practitioners are consistently faced with making ethical choices in the public interest. The key objective is therefore to identify the centrality of ethics in praxis. In this context, political liberal theory is empirically useful in exploring both the role of participants and the processes employed in strategic planning. A case study analysis generates key issues which are relevant to planning in the wider arena and an extensive series of interviews provides interesting insights into the dynamic between those involved and the effectiveness of procedures followed.

Engaging in the Crooked Timbre of Humanity: Value Pluralism and Social work

The field of social work ethics is changing. While more established positions, such as utilitarianism and deontology, continue to influence social work thinking and practice, emergent approaches are taking hold, leading to a radical examination of social work as an ethical discipline. To contribute to this unfolding debate, this article examines Isaiah Berlin's notion of value pluralism and its contribution to social work. The argument proceeds by summarising and categorising some of the traditional and emergent theories shaping social work according to metaphors of the ‘head’ (the justice-oriented, rational approaches) and the ‘heart’ (the grounded, particularistic and care-focused approaches). Berlin's value pluralism is then adopted to contend that social work needs to hold both ‘head’ and ‘heart’ ethics in a vital equilibrium to generate the ethics of the ‘hand’ (i.e. the practical response to contested areas of need) and the ‘feet’ (the commitment to change and well-being). These metaphors are then mapped on to a decision-making process and applied to the fraught area of adoption without parental consent

Tigecycline challenge triggers sRNA production in Salmonella enterica serovar Typhimurium

Background: Bacteria employ complex transcriptional networks involving multiple genes in response to stress, which is not limited to gene and protein networks but now includes small RNAs (sRNAs). These regulatory RNA molecules are increasingly shown to be able to initiate regulatory cascades and modulate the expression of multiple genes that are involved in or required for survival under environmental challenge. Despite mounting evidence for the importance of sRNAs in stress response, their role upon antibiotic exposure remains unknown. In this study, we sought to determine firstly, whether differential expression of sRNAs occurs upon antibiotic exposure and secondly, whether these sRNAs could be attributed to microbial tolerance to antibiotics.

Results: A small scale sRNA cloning strategy of Salmonella enterica serovar Typhimurium SL1344 challenged with half the minimal inhibitory concentration of tigecycline identified four sRNAs (sYJ5, sYJ20, sYJ75 and sYJ118) which were reproducibly upregulated in the presence of either tigecycline or tetracycline. The coding sequences of the four sRNAs were found to be conserved across a number of species. Genome analysis found that sYJ5 and sYJ118 mapped between the 16S and 23S rRNA encoding genes. sYJ20 (also known as SroA) is encoded upstream of the tbpAyabKyabJ operon and is classed as a riboswitch, whilst its role in antibiotic stress-response appears independent of its riboswitch function. sYJ75 is encoded between genes that are involved in enterobactin transport and metabolism. Additionally we find that the genetic deletion of sYJ20 rendered a reduced viability phenotype in the presence of tigecycline, which was recovered when complemented. The upregulation of some of these sRNAs were also observed when S. Typhimurium was challenged by ampicillin (sYJ5, 75 and 118); or when Klebsiella pneumoniae was challenged by tigecycline (sYJ20 and 118).

Conclusions: Small RNAs are overexpressed as a result of antibiotic exposure in S. Typhimurium where the same molecules are upregulated in a related species or after exposure to different antibiotics. sYJ20, a riboswitch, appears to possess a trans-regulatory sRNA role in antibiotic tolerance. These findings imply that the sRNA mediated response is a component of the bacterial response to antibiotic challenge.

"Out of sync": The breakdown of economic sentiment cycles in the E.U.

We present empirical evidence about the properties of economic sentiment cycle synchronization for Germany, France and the UK and compare them with the `crisis' countries Italy, Spain, Portugal and Greece. Instead of using output data we prefer to focus on the economic sentiment indicator (ESI), a forward-looking, survey-based variable consistently available from 1985. The cyclical nature of the ESI allows us to analyze the presence or not of synchronicity among country pairs before and after the onset of the financial crisis. Our results show that ESI movements were mostly synchronous before 2008 but they exhibit a breakdown after 2008, with this feature being more prominent in Greece. We also find that, after the political manoeuvring of the past two years, a cycle re-integration or re-synchronization is on the way. An analysis of the evolution of the synchronicity measures indicates that they can potentially be used to identify sudden phase breaks in ESI co-movement and they can offer a signal as to when the EU economies are getting “in” or “out of sync”.

Complementary Therapy: perceptions of older people with lung or colorectal cancer

Aim: To explore how older people with lung and colorectal cancer
view registered complementary therapy (CT) services in Northern
Ireland. Background: A literature review highlighted gaps around
information, access, and communication between patients and health
professionals regarding CT services. Methods: Using structured
interviews, a survey of 68 patients in one hospital and one hospice was
conducted in Belfast, Northern Ireland. Results: All respondents felt
that CT services should be better promoted and more easily
accessible to older people with cancer. Some patients were concerned
about the lack of written information provided regarding CT services,
which they believed led to poorer uptake and uncertainty regarding
the potential benefits. Others were concerned that engaging in or
disclosing CT usage might negatively affect existing relationships with
medical professionals. Conclusion: Patients should be offered high
quality written information on CT services to enable choice, improve
knowledge, and promote wider access. Increased physician education
may facilitate provision of such information.

Queer Spaces, Sexual Violence and the Desire for Safety

Queer politics and spaces have historically been associated with ideals of sexual liberation. They are conceptualised as spaces where sex, and its intersections with intimacy, friendship and love can be explored outside of normative frameworks which value monogamous reproductive heterosexuality at the expense of other non-normative sexual expressions. In recent years, however, autonomous queer spaces such as the global Queeruption gatherings and other queer community spaces in Australia have become increasingly concerned with the presence and danger of sexual violence in queer communities. Almost without exception, this danger has been responded to through the creation of ‘safe(r) spaces’ policies, generally consisting of a set of guidelines and proscribed behaviours which individuals must agree to in order to participate in or attend the event or space. The guidelines themselves tend to privilege of sexual politics of affirmative verbal consent, insisting that such consent should be sought prior to any physical or sexual contact, inferring that a failure to do so is ethically unacceptable within. This chapter reflects on the attempts to construct queer communities as ‘safer spaces,’ arguing that the concepts of consent and safety are inadequate to develop a queer response to sexual violence. Such a response, it argues, must be based on the openness to possibilities and refusal of sexual restrictions and regulations that have always been central elements of queer theory and politics.

Evidence-based policymaking and the public interest: lessons in legitimacy

This paper draws upon an analysis of regional spatial planning to highlight the centrality of ethics in praxis. In this context political liberalism is particularly helpful in developing a deeper understanding of the activities of those engaged in planning decision making. At the most basic level it demonstrates the importance of not only using shared liberal values as the foundation for public discourses but also achieving consensus through the development of an inclusive evidence base, derived from both lay and professional knowledge. Specifically, political liberalism provides a practical critique, enabling judgments to be made on problems which pervade operational planning practice and an evaluation to be conducted of the dynamic between and actions of participants.
