Birkenhead Sixth Form College: Opening up remote access to the college network brings wider benefits to all

Birkenhead Sixth Form College implemented a virtual network to open up remote access to the college network for its students, staff and governors. In particular, for childcare students on work placements, this has meant 24/7 secure access to their work and resources, and the ability to make timely updates to their work evidence logs. The impact is better continuity of learning and a dramatic increase in the hand-in rate for work. For the staff, governors and college as a whole, the benefits of anytime-access to the network are more than were envisaged at the outset; not only is it saving them valuable time and eliminating the need for large print runs, it is expected to bring cost-savings to the College in the long term.

Valuing equity-linked death benefits in jump diffusion models

The paper is motivated by the valuation problem of guaranteed minimum death benefits in various equity-linked products. At the time of death, a benefit payment is due. It may depend not only on the price of a stock or stock fund at that time, but also on prior prices. The problem is to calculate the expected discounted value of the benefit payment. Because the distribution of the time of death can be approximated by a combination of exponential distributions, it suffices to solve the problem for an exponentially distributed time of death. The stock price process is assumed to be the exponential of a Brownian motion plus an independent compound Poisson process whose upward and downward jumps are modeled by combinations (or mixtures) of exponential distributions. Results for exponential stopping of a Lévy process are used to derive a series of closed-form formulas for call, put, lookback, and barrier options, dynamic fund protection, and dynamic withdrawal benefit with guarantee. We also discuss how barrier options can be used to model lapses and surrenders.

Characteristics, socioeconomic benefits and household livelihoods of beef buffalo and beef cattle farming in Northeast Thailand

Since the Thai economy experiences rapid growth, agricultural systems, i.e. crop-livestock systems, are changing rapidly. On account of these changes, buffalo and cattle production has to be re-examined in terms of performance characteristics and roles of livestock for farm households in order to initiate suitable development programmes. Therefore, this study aimed to investigate the present characteristics of beef buffalo and beef cattle farms in Northeast Thailand. Using a semi-structured questionnaire, 121 randomly selected beef buffalo and beef cattle farms were interviewed in Nakhon Ratchasima province between October 2007 and May 2008. Both buffaloes and cattle were mostly integrated in mixed crop-livestock systems with medium to large farm sizes (7.9 ha), whereof less than half of the area was used for livestock. Family members were mainly responsible for the different activities of livestock farming and salaried labourers were only found on large-scale farms. The dominant roles of livestock were income generation to build up wealth or savings, the coverage of expected and unexpected expenses and earning of regular and additional income. Another important issue was the improvement of the social status, which increased with herd size. In order to improve farmers’ livelihoods and develop sustainable farming systems in Northeast Thailand the changing economic circumstances of cattle and especially buffalo production should receive more attention of researchers, governmental institutions and stakeholders.

Europe’s biocidal products directive: benefits and costs in urban pest management

The European Commission’s Biocidal Products Directive (Council Directive 98/8 EC), known as the BPD, is the largest regulatory exercise ever to affect the urban pest control industry. Although focussed in the European Union its impact is global because any company selling pest control products in the EU must follow its principles. All active substances, belonging to 23 different biocidal product types, come within the Directive’s scope of regulatory control. This will eventually involve re-registration of all existing products, as well as affecting any new product that comes to the market. Some active substances, such as the rodenticides and insecticides, are already highly regulated in Europe but others, such as embalming fluids, masonry preservatives, disinfectants and repellents/attractants will come under intensive regulatory scrutiny for the first time. One of the purposes of the Directive is to offer enhanced protection for human health and the environment. The potential benefit for suppliers of pest control products is mutual recognition of regulatory product dossiers across 25 Member States of the European Union. This process, requiring harmonisation of all regulatory decision-making processes, should reduce duplicated effort and, potentially, allow manufacturers speedier access to European markets. However, the cost to industry is enormous, both in terms of the regulatory resources required to assemble BPD dossiers and the development budgets required to conduct studies to meet its new standards. The cost to regulatory authorities is also tremendous, in terms of the need to upgrade staff capabilities to meet new challenges and the volume of the work expected by the Commission when they are appointed the Rapporteur Member State (RMS) for an active substance. Users of pest control products will pay a price too. The increased regulatory costs of maintaining products in the European market are likely to be passed on, at least in part, to users. Furthermore, where the costs of meeting new regulatory requirements cannot be recouped from product sales, many well-known products may leave the market. For example, it seems that in future few rodenticides that are not anticoagulants will be available within the EU. An understanding of the BPD is essential to those who intend to place urban pest control products on the European market and may be useful to those considering the harmonisation of regulatory processes elsewhere. This paper reviews the operation of the first stages of the BPD for rodenticides, examines the potential benefits and costs of the legislation to the urban pest control industry and looks forward to the next stages of implementation involving all insecticides used in urban pest management.

Functional dependence and caregiver burden in Alzheimer's disease: a controlled trial on the benefits of motor intervention

Background: Cognitive decline has a negative impact on functional activities in Alzheimer's disease. Investigating the effects of motor intervention with the intent to reduce the decline in functionality is an expected target for patients and caregivers. The aim of this study was to verify if a 6-month motor intervention programme promoted functionality in Alzheimer's patients and attenuated caregivers' burden. Methods: The sample comprised 32 community patients with Alzheimer's disease and their 32 respective caregivers. Patients were divided into two groups: 16 participated in the motor intervention programme and 16 controls. Subjects performed 60 minutes of exercises, three times per week during the 6-month period, to improve flexibility, strength, agility and balance. Caregivers followed the procedures with their patients during this period. Functionality was evaluated by the Berg Functional Balance Scale and the Functional Independence Measure. Caregivers completed the Neuropsychiatric Inventory Caregiver Distress Scale and the Zarit Carer Burden Scale. Two-way ANOVA was used to verify the interaction between time (pre- and post-intervention) and the motor intervention program. Results: While patients in the motor programme preserved their functionality, as assessed by the Functional Independence Measure, the controls suffered a relative decline (motor intervention group: from 109.6 to 108.4 vs controls: from 99.5 to 71.6; P= 0.01). Patients from motor intervention also had better scores than the controls on functional balance assessed by Berg scale (F: 22.2; P= 0.001). As assessed by the Neuropsychiatric Inventory and Zarit scale, burden was reduced among caregivers whose patients participated in the motor intervention programme compared with caregivers whose patients did not participate in this programme (Neuropsychiatric Inventory, caregiver's part: F: 9.37; P= 0.01; Zarit: F: 11.28; P= 0.01). Conclusion: Patients from the motor intervention group showed reduced functional decline compared to the controls, and there was an associated decrease in caregivers' burden.

Importance and Benefits of OPEN SCIENCE for Ubiquitous Sharing, Dissemination and Impact

While openness is well applied to software development and exploitation (open sources), and successfully applied to new business models (open innovation), fundamental and applied research seems to lag behind. Even after decades of advocacy, in 2011 only 50% of the public-funded research was freely available and accessible (Archambault et al., 2013). The current research workflows, stemming from a pre-internet age, result in loss of opportunity not only for the researchers themselves (cf. extensive literature on topic at Open Access citation project, http://opcit.eprints.org/), but also slows down innovation and application of research results (Houghton & Swan, 2011). Recent studies continue to suggest that lack of awareness among researchers, rather than lack of e-infrastructure and methodology, is a key reason for this loss of opportunity (Graziotin 2014). The session will focus on why Open Science is ideally suited to achieving tenure-relevant researcher impact in a “Publish or Perish” reality. Open Science encapsulates tools and approaches for each step along the research cycle: from Open Notebook Science to Open Data, Open Access, all setting up researchers for capitalising on social media in order to promote and discuss, and establish unexpected collaborations. Incorporating these new approaches into a updated personal research workflow is of strategic beneficial for young researchers, and will prepare them for expected long term funder trends towards greater openness and demand for greater return on investment (ROI) for public funds.

Correcting for bias when estimating the cost of hospital-acquired infection : an analysis of lower respiratory tract infections in non-surgical patients

Hospital acquired infections (HAI) are costly but many are avoidable. Evaluating prevention programmes requires data on their costs and benefits. Estimating the actual costs of HAI (a measure of the cost savings due to prevention) is difficult as HAI changes cost by extending patient length of stay, yet, length of stay is a major risk factor for HAI. This endogeneity bias can confound attempts to measure accurately the cost of HAI. We propose a two-stage instrumental variables estimation strategy that explicitly controls for the endogeneity between risk of HAI and length of stay. We find that a 10% reduction in ex ante risk of HAI results in an expected savings of £693 ($US 984).
