The Copney Stone Circle Complex, Co. Tyrone, N. Ireland, is an important Bronze Age site forming part of the Mid-Ulster Stone Circle Complex. The Environment Service: Historic Monuments and Buildings (ESHMB) initiated a program of bog-clearance in August 1994 to excavate the stone circles. This work was completed by October 1994 and the excavated site was surveyed in August 1995. Almost immediately, the rate at which the stones forming the circles were breaking down was noted and a program of study initiated to make recommendations upon the conservation of this important site. Digital photogrammetric techniques were applied to aerial images of the stone circles and digital terrain models created from the images at a range of scales. These provide base data sets for comparison with identical surveys to be completed in successive years and will allow the rate of deterioration, and the areas most affected, of the circles to be determined. In addition, a 2D analysis of the stones provides an accurate analysis of the absolute 2D dimensions of the stones for rapid desktop computer analysis by researchers remote from the digital photogrammetric workstation used in the survey.
The products of this work are readily incorporated into web sites, educational packages and databases. The technique provides a rapid and user friendly method of presentation of a large body of information and measurements, and a reliable method of storage of the information from Copney should it become necessary to re-cover the site.

The purpose of this study was to explore nurses' perceptions of their current practices related to administering pain medications to long-term care (LTC) residents. A cross-sectional survey design was used, including both quantitative and open-ended questions. Data were collected from 165 nurses (59% response rate) at nine LTC homes in southern Ontario, Canada. The majority (85%) felt that the medication administration system was adequate to help them manage residents' pain and 98% felt comfortable administering narcotics. In deciding to administer a narcotic, nurses were influenced by pain assessments, physician orders, diagnosis, past history, effectiveness of non-narcotics and fear of making dosage miscalculations or developing addictions. Finally, most nurses stated that they trusted the physicians and pharmacists to ensure orders were safe. These findings highlight nurses' perceptions of managing pain medications in LTC and related areas where continuing education initiatives for nurses are needed.

Background Advance care planning (ACP) facilitates communication
and understanding of preferences, nevertheless the use of
ACPs in primary care for patients with dementia is low. The disease’s
uncertain course and the inability to communicate with
the patient living with dementia are significant challenges for
GPs.
Aim The purpose of this study was to describe the attitudes and
practice preferences of GPs working within the UK’s National
Health System (NHS) regarding communication, and decisionmaking
for patients with dementia and their families
Methods A cross-sectional survey, using a purposive, cluster sample
of GPs across Northern Ireland with registered dementia
patients was used.
Results One hundred and thirty-three GPs (40.6%) participated
in the survey, representing 60.9% of surveyed practices. While
most respondents regarded dementia as a terminal disease
(96.2%) only 37.6% felt that palliative care applied equally from
the time of diagnosis to severe dementia. While most respondents
thought that early discussions would facilitate decision-making
during advanced dementia (61%), respondents were divided
on whether ACP should be initiated at the time of diagnoses
(39.8% in favour vs 45.8% disagreed). Interestingly, GPs who
were longer in practice placed greater importance on the presence
of an advance directive (F (2, 124) = 3.38, p = 0.037).
Discussion The timing of initiating ACP varies across individuals
requiring GPs to carefully consider strategies and receptiveness
of the patient and family carer.
Conclusion The findings promote both ongoing training in communication
and dementia management for GPs to meet the
needs of their patients living with dementia.

During benthic cultivation Mytilus edulis (blue mussels) are subject to predation pressure from a number of predators including Carcinus maenas (shore crabs). This predator can be responsible for substantial losses of mussels from the fishery and a full understanding of the predator–prey relationship between M. edulis and C. maenas is required to ensure attempts that reduce predatory pressure and subsequent commercial loss are successful. Whilst much work has examined the prey–predator size relationships between C. maenas and M. edulis, far less research has investigated how stress, such as periods of extended aerial exposure, may affect these relationships. We tested whether profit in terms of calories gained by crabs consuming mussels stressed by aerial exposure for 48 h differed from that of mussels at ambient conditions and whether being stressed affected the mussel's likelihood of predation. We also tested whether the size relationship between predators and their prey differed when mussels were stressed. We found that the profitability of prey (calories gained per second of handling time) did not vary between stressed and unstressed mussels. Handling times for stressed and unstressed mussels were similar, even when crabs were presented with mussels of the maximum size that they are able to consume. Small crabs were more likely to reject a mussel of preferred size if it was unstressed, suggesting that crabs may be able to assess that these mussels would require extra effort to break into and consume. Our findings suggest that the predator–prey relationship between mussels and crabs is not altered when mussels are stressed. C. maenas remains a voracious predator and regardless of the condition of mussels laid on commercial beds there is a need to control this predator in attempt to reduce losses in the benthic fishery.

Introduction
The role of the pharmacist centers on ensuring the safe and effective use of medicines, including over-the-counter (OTC) medicines. It is important to ascertain pharmacy students’ use and opinions on OTC medicines, given that they are the pharmacists of the future and that this market continues to expand. This study aimed to investigate Queen’s University Belfast (QUB) final year pharmacy students’ use and views on OTC medicines. Scarce work has been conducted in this area to date.
Methods
Following ethical approval and a pilot study, all students (n=155) were invited to participate in a self-completed questionnaire (n=20 questions), distributed at a mandatory class. Descriptive statistics and non-parametric tests (Chi-squared and Mann Whitney U-test) were used for data analyses.
Results
The response rate was 99.4% (154/155). The majority (153/155) reported using OTC medicines; the key consideration during personal product selection was effectiveness. Most [96.1% (147/153)] were in agreement that safety was the over-riding concern during OTC consultations. While 96.1% (149/155) considered that using an evidence-based approach improved the quality of patient care, 68.0% (104/153) would be prepared to sell a product that lacks evidence of effectiveness, provided it would not cause harm.
Conclusions
The importance of evidence of effectiveness was acknowledged, yet many students in this study were prepared to recommend unproven products. Further strategies are required at QUB to ensure this routine consideration alongside safety in practice.
