Tourism stakeholder exclusion and conflict in a small island

Research in the Isle of Man, British Isles, reveals limited and dysfunctional collaboration between stakeholders, and in particular between public and private sector actors. Power and influence over tourism decision making is generally felt to be restricted to a small and opaque network. Moreover, different levels of interest in and support for tourism further divide stakeholders. Various negative consequences are shown to arise from this absence of collaboration, including a lack of shared vision or future strategy for local tourism, and high levels of mutual mistrust between stakeholders. Resulting conflict, wasted resources, lost enthusiasm and lack of strategic direction appear to undermine the current and future management of island tourism. Emphasised by research is the importance of stakeholder collaboration to sustainable tourism management and underlying factors which may enhance or undermine. Focus on dysfunctional collaboration and the small island setting makes a unique contribution to the existing literature

Gait deficiencies associated with peripheral artery disease are different than chronic obstructive pulmonary disease

Objective: Previous studies have indicated that patients with peripheral artery disease (PAD), display significant differences in their kinetic and kinematic gait characteristics when compared to healthy, aged-matched controls. The ability of patients with chronic obstructive pulmonary disease (COPD) to ambulate is also limited. These limitations are likely due to pathology-driven muscle morphology and physiology alterations establish in PAD and COP, respectively. Gait changes in PAD were compared to gait changes due to COPD to further understand how altered limb muscle due to disease can alter walking patterns. Both groups were independently compared to healthy controls. It was hypothesized that both patients with PAD and COPD would demonstrate similar differences in gait when compared to healthy controls. Methods: Patients with PAD (n=25), patients with COPD (n=16), and healthy older control subjects (n=25) performed five walking trials at self-selected speeds. Sagittal plane joint kinematic and kinetic group means were compared. Results: Peak values for hip flexion angle, braking impulse, and propulsive impulse were significantly reduced in patients with symptomatic PAD compared to patients with COPD. After adjusting for walking velocity, significant reductions (p Conclusions: The results of this study demonstrate that while gait patterns are impaired for patients with PAD, this is not apparent for patients with COPD (without PAD). PAD (without COPD) causes changes to the muscle function of the lower limbs that affects gait even when subjects walk from a fully rested state. Altered muscle function in patients with COPD does not have a similar effect

ElectrochemicalN-demethylation of tropane alkaloids

A practical, efficient, and selective electrochemicalN-demethylation method of tropane alkaloids to their nortropane derivatives is described. Nortropanes, such as noratropine and norscopolamine, are important intermediates for the semi-synthesis of the medicines ipratropium or oxitropium bromide, respectively. Synthesis was performed in a simple home-made electrochemical batch cell using a porous glassy carbon electrode. The reaction proceeds at room temperature in one step in a mixture of ethanol or methanol and water. The method avoids hazardous oxidizing agents such as H(2)O(2)orm-chloroperbenzoic acid (m-CPBA), toxic solvents such as chloroform, as well as metal-based catalysts. Various key parameters were investigated in electrochemical batch or flow cells, and the optimized conditions were used in batch and flow-cells at gram scale to synthesize noratropine in high yield and purity using a convenient liquid-liquid extraction method without any need for chromatographic purification. Mechanistic studies showed that the electrochemicalN-demethylation proceeds by the formation of an iminium intermediate which is converted by water as the nucleophile. The optimized method was further applied to scopolamine, cocaine, benzatropine, homatropine and tropacocaine, showing that this is a generic way ofN-demethylating tropane alkaloids to synthesize valuable precursors for pharmaceutical products

New urbanism, crime and the suburbs: a review of the evidence

Sustainability now influences government policy in the UK, Australia and USA and planning policy currently advocates high density, mixed-use residential developments in 'walkable', permeable neighbourhoods, close to public transport, employment and amenities. This clearly demonstrates the growing popularity, influence and application of New Urbanist ideas.This paper reviews the criminological research relating to New Urbanism associated with the three key issues of permeability, rear laneway car parking and mixed-use development. These key issues are discussed from an environmental criminology perspective and challenge New Urbanist assumptions concerning crime. The paper proposes that crime prevention through environmental design (CPTED) and its crime risk assessment model represents a valuable tool for New Urbanists to utilise to reduce opportunities for crime and tackle fear of crime in the community. Recommendations for future research and collaboration are discussed

Use of weighted Fourier linear combiner filters to estimate lower trunk 3D orientation from gyroscope sensors data.

BACKGROUND: The present study aimed at devising a data processing procedure that provides an optimal estimation of the 3-D instantaneous orientation of an inertial measurement unit (IMU). This result is usually obtained by fusing the data measured with accelerometers, gyroscopes, and magnetometers. Nevertheless, issues related to compensation of integration errors and high sensitivity of these devices to magnetic disturbances call for different solutions. In this study, a method based on the use of gyroscope data only is presented, which uses a Weighted Fourier Linear Combiner adaptive filter to perform a drift-free estimate of the 3D orientation of an IMU located on the lower trunk during walking. METHODS: A tuning of the algorithm parameters and a sensitivity analysis to its initial conditions was performed using treadmill walking data from 3 healthy subjects. The accuracy of the method was then assessed using data collected from 15 young healthy subjects during treadmill walking at variable speeds and comparing the pitch, roll, and yaw angles estimated from the gyroscopes data to those obtained with a stereophotogrammetric system. Root mean square (RMS) difference and correlation coefficients (r) were used for this purpose. RESULTS: An optimal set of values of the algorithm parameters was established. At all the observed speeds, and also in all the various sub-phases, the investigated angles were all estimated to within an average RMS difference of less than 1.2 deg and an average r greater than 0.90. CONCLUSIONS: This study proved the effectiveness of the Weighted Fourier Linear Combiner method in accurately reconstructing the 3D orientation of an IMU located on the lower trunk of a subject during treadmill walking. This method is expected to also perform satisfactorily for overground walking data and to be applicable also to other "quasi-periodic" tasks, such as squatting, rowing, running, or swimming

Digital disruption of dietetics: are we ready?

Digital health is transforming the delivery of health care around the world to meet the growing challenges presented by ageing populations with multiple chronic conditions. Digital health technologies can support the delivery of personalised nutrition care through the standardised Nutrition Care Process (NCP) by using personal data and technology-supported delivery modalities. The digital disruption of traditional dietetic services is occurring worldwide, supporting responsive and high-quality nutrition care. These disruptive technologies include integrated electronic and personal health records, mobile apps, wearables, artificial intelligence and machine learning, conversation agents, chatbots, and social robots. Here, we outline how digital health is disrupting the traditional model of nutrition care delivery and outline the potential for dietitians to not only embrace digital disruption, but also take ownership in shaping it, aiming to enhance patient care. An overview is provided of digital health concepts and disruptive technologies according to the four steps in the NCP: nutrition assessment, diagnosis, intervention, and monitoring and evaluation. It is imperative that dietitians stay abreast of these technological developments and be the leaders of the disruption, not simply subject to it. By doing so, dietitians now, as well as in the future, will maximise their impact and continue to champion evidence-based nutrition practice
