The article also lists some general resources for disaster planning and preparedness.

This is a viewpoint article discussing the MayDay initiative, and ways to enhance disaster planning and preparedness in cultural institutions.

The article finds that MayDay 2006 launched a new initiative for disaster preparedness and planning. The idea is that this will become an annual time when cultural institutions dedicate the day to emergency preparedness and planning. Selected results of the first MayDay are described and the ideas for MayDay 2007 events are listed.

This article provides information and examples of appropriate MayDay activities by describing MayDay 2006 events and providing pointers to online resources to assist archives and museums identify activities for MayDay 2007.

Since Hurricane Katrina, substantial focus has been placed on disaster planning and preparedness in cultural organizations. This article promotes concrete actions that can be taken to enhance disaster planning and preparedness in cultural institutions and identifies resources on the Internet to help archives and museums in this endeavor.

As social networks have developed to be a ubiquitous platform of public opinion spreading, it becomes more and more crucial for maintaining social security and stability by accurately predicting various trends of public opinion dissemination in social networks. Considering the fact that the dissemination of online public opinion is a dynamic process full of uncertainty and complexity, this study establishes a novel conformable fractional discrete grey model with linear time-varying parameters, namely the CFTDGM(1,1) model, for more accurate prediction of online public opinion trends.

First, the conformable fractional accumulation and difference operators are employed to build the CFTDGM(1,1) model for enhancing the traditional integer-order discrete grey model with linear time-varying parameters. Then, to improve forecasting accuracy, a base value correction term is introduced to optimize the iterative base value of the CFTDGM(1,1) model. Next, the differential evolution algorithm is selected to determine the optimal order of the proposed model through a comparison with the whale optimization algorithm and the particle swarm optimization algorithm. The least squares method is utilized to estimate the parameter values of the CFTDGM(1,1) model. In addition, the effectiveness of the CFTDGM(1,1) model is tested through a public opinion event about “IG team winning the championship”. Finally, we conduct empirical analysis on two hot online public opinion events regarding “Chengdu toddler mauled by Rottweiler” and “Mayday band suspected of lip-syncing,” to further assess the prediction ability and applicability of the CFTDGM(1,1) model by comparison with seven other existing grey models.

The test case and empirical analysis on two recent hot events reveal that the CFTDGM(1,1) model outperforms most of the existing grey models in terms of prediction performance. Therefore, the CFTDGM(1,1) model is chosen to forecast the development trends of these two hot events. The prediction results indicate that public attention to both events will decline slowly over the next three days.

A conformable fractional discrete grey model is proposed with the help of conformable fractional operators and a base value correction term to improve the traditional discrete grey model. The test case and empirical analysis on two recent hot events indicate that this novel model has higher accuracy and feasibility in online public opinion trend prediction.

The purpose of this paper was to prospectively audit an eye department's quality of note keeping in a casualty setting.

The paper found that locally agreed standards for quality of documentation were based on criteria integral to the patient pathway. Assessment of local practice, was carried out, by reviewing patient records. The results were compared against locally agreed standards and indicators were divided into those, which the unit performed well, and those, which could be improved, necessitating action. Changes in practice, including education and document redesign, were carried out. The results were re‐audited and compared with previous cycles.

The paper found that 145 records were audited in four cycles over a nine‐month period. The department performed consistently well in the majority of indicators. All but one of the poorly performing indicators improved with the changes in practice. These improvements were sustained with repeated re‐audit.

The paper shows that good note keeping in the unpredictable setting of the casualty clinic is difficult, which impacts on patient care. This simple audit has had a beneficial effect on the unit's standard of note keeping in the casualty environment and can easily be adapted to improve documentation in other clinical specialties and scenarios.

This paper investigates the short-term market impact of the beginning of the military conflict between Russia and Ukraine (February 24, 2022) on a set of airline stocks listed.

This study uses an event study methodology, cross-section analyses and interaction effects to study the effect of the war on airline stock prices and firm-specific characteristics that explain the cumulative abnormal return.

The authors observe a negative and statistically significant stock price reaction at and around the beginning of the military conflict between Russia and Ukraine, for 74 listed airlines. These results are consistent with investment portfolio rebalancing and asset pricing perspective. Moreover, this study's results show a higher negative stock market reaction for airlines based in Europe. Empirical evidence suggests the existence of a “proximity penalty” for European companies. Finally, this study's results provide insights into which airline-specific characteristics emerge as value drivers. Larger, well-capitalized (high liquidity and low debt) and profitable airlines firms with less institutional ownership have superior stock market returns and show more able to handle with the losses resulting from the war.

This paper fills a gap in the literature about the impact of the Russia–Ukraine war on the airline industry.

The classic audit cycle has been applied to the prescribing practice to improve aspects of the quality of prescribing in the setting of a department of health care for older people in a district general hospital. Details the methods used both to increase the appropriate prescribing of drugs of proven benefit, and also to restrict the use of drugs which may prove hazardous. The latter provides an example of risk management. Also discusses the dilemmas posed in treating older people with multiple pathologies, on the one hand, trying to avoid an ageist approach, on the other, attempting to minimise the pitfalls of polypharmacy.

Disappearance of a Reims Cessna F172N light aircraft after loss of radar contact when not a great distance from one of the Channel Islands, and subsequent recovery of the engine from the sea bed 13 months later, is a rare occurrence. No trace was ever found of the pilot (the sole occupant) or of the rest of the aircraft. It was on a flight from Shoreham to Jersey in January, 1985 and the pilot had obtained the latest Jersey weather after landing from a previous short flight. Guernsey weather was similar to the forecast obtained and the aftercast indicated that the cloud cover would increase and lower in the area of the Channel Islands and that the risk of severe icing and low level turbulence would also have increased in the vicinity.

A new Company, Rentatank Ltd., 20 Mayday Road, Thornton Heath, Surrey CR4 7HL, has been launched to provide a rental service for intermediate bulk containers (IBC's). For the first time in the U.K. a range of containers from 450 litres (100 gallons) to 3,000 litres (665 gallons) can be rented. Previously IBC's have tended to be regarded as items of capital expenditure, but with typical rental rates of 60p to £1 per day users can now consider them as revenue items.

AFTER three major failure of rudders, these components are to be replaced on all seven of British Airways' Concordes. It is intended that manufacture and fitting of the rudders will be completed by April, 1993. The incidents occured in 1989, 1991 and in March this year.

Following engine start on a Bell Jetranger helicopter, the pilot commented on a high frequency vibration which was apparent through the pedals. Once the aircraft had lifted into the hover, the vibration could no longer be detected and the helicopter departed Newmarket to return to Blackbushe. During the flight a short duration noise was made by the helicopter which was variously described by witnesses on the ground, as a ‘sharp crack’, ‘similar to a car gearbox breaking up’ and ‘stuttering like a car misfire’. After this, the helicopter began a gentle right turn to the north, towards the town of Crowthorne. The ground speed appeared to reduce to between 80 and 85 kt in this turn.
