Marketing a tourism industry in late stage decline: The case of the Isle of Man
Qualitative interviews in the Isle of Man uncovered local perceptions of a tourism industry in late stage decline. Social impacts of decline are pronounced including facilities loss, cultural changes and a heightening of perceived peripherality: which taken together undermine local identity. Tourists are welcomed as they help to affirm the pride residents have in their island in creating a more active atmosphere, provide social interaction opportunities and to combat negative stereotyping. Thus findings emphasise the diverse, unique and persistent benefits of tourism in the Isle of Man, despite its decline. Destination marketing recommendations are therefore made to better address the experiences and desires of communities experiencing decline
Polydopamine-lysophosphatidate-functionalised titanium: A novel hybrid surface finish for bone regenerative applications

This article is an open access article distributed under the terms and conditions of the Creative Commons Attribution (CC BY) license (http://creativecommons.org/licenses/by/4.0/). Aseptic loosening of total joint replacements (TJRs) continues to be the main cause of implant failures. The socioeconomic impact of surgical revisions is hugely significant; in the United Kingdom alone, it is estimated that Ā£135m is spent annually on revision arthroplasties. Enhancing the longevity of titanium implants will help reduce the incidence and overall cost of failed devices. In realising the development of a superior titanium (Ti) technology, we took inspiration from the growing interest in reactive polydopamine thin films for biomaterial surface functionalisations. Adopting a āone-potā approach, we exposed medical-grade titanium to a mildly alkaline solution of dopamine hydrochloride (DHC) supplemented with (3S)1-fluoro-3-hydroxy-4-(oleoyloxy)butyl-1-phosphonate (FHBP), a phosphatase-resistant analogue of lysophosphatidic acid (LPA). Importantly, LPA and selected LPA analogues like FHBP synergistically cooperate with calcitriol to promote human osteoblast formation and maturation. Herein, we provide evidence that simply immersing Ti in aqueous solutions of DHC-FHBP afforded a surface that was superior to FHBP-Ti at enhancing osteoblast maturation. The facile step we have taken to modify Ti and the biological performance of the final surface finish are appealing properties that may attract the attention of implant manufacturers in the future
Introduction : screen Londons
Our aim, in editing the āLondon Issueā of this journal, is to contribute to a conversation between scholars of British cinema and television, London historians and scholars of the cinematic city. In 2007, introducing the themed issue on āSpace and Place in British Cinema and Televisionā, Steve Chibnall and Julian Petley observed that it would have been possible to fill the whole journal with essays about the representation of London. This issue does just that, responding to the increased interest in cinematic and, to a lesser extent, televisual, Londons, while also demonstrating the continuing fertility of the paradigms of āspace and placeā for scholars of the moving image1. It includes a wide range of approaches to the topic of London on screen, with varying attention to British institutions of the moving image ā such as Channel Four or the British Board of Film Classification ā as well as to concepts such as genre, narration and memory. As a whole, the issue, through its juxtapositions of method and approach, shows something of the complexity of encounters between the terms āLondonā, ācinemaā and ātelevisionā within British film and television studies
Managing tourism decline: insights from the Isle of Man
Qualitative interviews conducted in the Isle of Man investigate local perceptions of a tourism industry in long-term decline: a development stage typically overlooked. Negative impacts of decline are revealed; including facilities loss, landscape erosion, and a heightened sense of peripherality. Together such impacts undermine local identity and attractiveness of place. Tourists are welcomed as they help to affirm the pride residents have in their island, create atmosphere, provide social interaction opportunities, stimulate positive emotions and combat negative stereotyping. Emphasised is the on-going importance of tourism impacts in a peripheral location. Practioner recommendations are therefore made calling attention to the need to more carefully manage the process of decline. Potential strategies for achieving this are signposted
Drought and the interannual variability of stem growth in an aseasonal, everwet forest
Linking drought to the timing of physiological processes governing tree growth remains
one limitation in forecasting climate change effects on tropical trees. Using
dendrometers, we measured fine-scale
growth for 96 trees of 25 species from 2013
to 2016 in an everwet forest in Puerto Rico. Rainfall over this time span varied,
including
an unusual, severe El NiƱo drought in 2015. We assessed how growing
season onset, median day, conclusion, and length varied with absolute growth rate
and tree size over time. Stem growth was seasonal, beginning in February, peaking in
July, and ending in November. Species growth rates varied between 0 and 8 mm/year
and correlated weakly with specific leaf area, leaf phosphorus, and leaf nitrogen, and
to a lesser degree with wood specific gravity and plant height. Drought and tree
growth were decoupled, and drought lengthened and increased variation in growing
season length. During the 2015 drought, many trees terminated growth early but did
not necessarily grow less. In the year following drought, trees grew more over a
shorter growing season, with many smaller trees showing a post-drought
increase in
growth. We attribute the increased growth of smaller trees to release from light limitation
as the canopy thinned because of the drought, and less inferred hydraulic
stress than larger trees during drought. Soil type accounted for interannual and interspecific
differences, with the finest Zarzal clays reducing tree growth. We conclude
that drought affects the phenological timing of tree growth and favors the post-drought
growth of smaller, sub-canopy
trees in this everwet forest
Risk factors for incident heart failure with preserved or reduced ejection fraction, and valvular heart failure, in a community-based cohort
Background: The lack of effective therapies for heart failure with preserved ejection fraction (HFpEF) reflects an incomplete understanding of its pathogenesis. Design: We analysed baseline risk factors for incident HFpEF, heart failure with reduced ejection fraction (HFrEF) and valvular heart failure (VHF) in a community-based cohort. Methods: We recruited 2101 men and 1746 women =60 years of age with hypertension, diabetes, ischaemic heart disease (IHD), abnormal heart rhythm, cerebrovascular disease or renal impairment. Exclusion criteria were known heart failure, left ventricular ejection fraction mild in severity. Median follow-up was 5.6 (IQR 4.6-6.3) years. Results: Median time to heart failure diagnosis in 162 participants was 4.5 (IQR 2.7-5.4) years, 73 with HFpEF, 53 with HFrEF and 36 with VHF. Baseline age and amino-terminal pro-B-type natriuretic peptide levels were associated with HFpEF, HFrEF and VHF. Pulse pressure, IHD, waist circumference, obstructive sleep apnoea and pacemaker were associated with HFpEF and HFrEF; atrial fibrillation (AF) and warfarin therapy were associated with HFpEF and VHF and peripheral vascular disease and low platelet count were associated with HFrEF and VHF. Additional risk factors for HFpEF were body mass index (BMI), hypertension, diabetes, renal dysfunction, low haemoglobin, white cell count and Ć-blocker, statin, loop diuretic, non-steroidal anti-inflammatory and clopidogrel therapies, for HFrEF were male gender and cigarette smoking and for VHF were low diastolic blood pressure and alcohol intake. BMI, diabetes, low haemoglobin, white cell count and warfarin therapy were more strongly associated with HFpEF than HFrEF, whereas male gender and low platelet count were more strongly associated with HFrEF than HFpEF. Conclusions: Our data suggest a major role for BMI, hypertension, diabetes, renal dysfunction, and inflammation in HFpEF pathogenesis; strategies directed to prevention of these risk factors may prevent a sizeable proportion of HFpEF in the community.

Effects of High Flavanol Dark Chocolate on Cardiovascular Function and Platelet Aggregation.
Regular consumption of chocolate and cocoa products has been linked to reduced cardiovascular mortality. This study compared the effects of high flavanol dark chocolate (HFDC; 1064mg flavanols/day for 6 weeks) and low flavanol dark chocolate (LFDC; 88mg flavanols/day for 6 weeks) on blood pressure, heart rate, vascular function and platelet aggregation in men with pre-hypertension or mild hypertension. Vascular function was assessed by pulse wave analysis using radial artery applanation tonometry in combination with inhaled salbutamol (0.4 mg) to assess changes due to endothelium-dependent vasodilatation. HFDC did not significantly reduce blood pressure compared to baseline or LFDC. Heart rate was increased by LFDC compared to baseline, but not by HFDC. Vascular responses to salbutamol tended to be greater after HFDC. Platelet aggregation induced by collagen or the thromboxane analogue U46619 was unchanged after LFDC or HFDC, whereas both chocolates reduced responses to ADP and the thrombin receptor activator peptide, SFLLRNamide (TRAP6), relative to baseline. Pre-incubation of platelets with theobromine also attenuated platelet aggregation induced by ADP or TRAP6. We conclude that consumption of HFDC confers modest improvements in cardiovascular function. Platelet aggregation is modulated by a flavanol-independent mechanism that is likely due to theobromine.This study was supported by a grant (to R. Corder) from Barry Callebaut Belgium N
Diversity and inclusion in conservation: A proposal for a marine diversity network
Low diversity among scientists and practitioners is rampant in conservation. Currently,
conservation professionals do not reflect the same diversity of perspectives and
experiences of the world as the communities who bear the largest burden for
implementingāor adverse consequences for failing to implementāconservation action.
Acknowledging and describing the problem is important. But policies and programmes
must also be put in place to correct it. Here, we highlight some measurable benefits
of workforce diversity, and give an overview of some of the barriers to inclusion
in marine conservation that help perpetuate low workforce diversity. Importantly, we
underscore actions that both individuals and groups can take to alleviate such barriers.
In particular, we describe the establishment of an online Marine Diversity Network,
which conference participants proposed during a focus group meeting at the 4th
International Marine Conservation Congress. The network will serve to bring together
people from across the globe, from a variety of backgrounds, and from all career stages,
to share knowledge, experiences and ideas, to provide and receive mentorship in marine
conservation, and to forge new collaborations. Removing barriers to diverse participation
requires coordinated, mindful actions by individuals and organizations. We hope that the
proposed network and other actions presented in this paper find widespread support,
and that they might serve both as inspiration and guide to other groups concerned with
increasing diversity and inclusivity
A multi-country level analysis of the environmental attitudes and behaviours among young consumers
Environmental issues have become more prominent internationally and are increasingly featured in discussion by governments, business and academics. This paper presents the results of a study which examines the concerns for environmental issues and purchase behaviours of a sample of 1173 young consumers in England, Germany, Portugal and Spain; countries which represent different realities in terms of economic development, social context and cultural issues. An analysis of the differences between the respondents from the four countries regarding concepts such as man-nature orientation, generativity, environmental concern, consumer perceived effectiveness, conservation behaviour and environmentally-friendly buying behaviour is presented. The results obtained confirm the existence of significant differences between countries for almost all variables. Ā© 2013 Copyright Taylor and Francis Group, LLC
Autoimmune thyroiditis in antinuclear antibody positive children without rheumatologic disease
<p>Abstract</p> <p>Background</p> <p>Children are commonly referred to a pediatric rheumatology center for the laboratory finding of an Anti-nuclear antibody (ANA) of undetermined significance. Previous studies regarding adult rheumatology patients have supported an association between ANA and anti-thyroid antibodies, with the prevalence of thyroid antibodies being significantly higher in patients referred to a rheumatology center for an ANA without evidence of connective tissue disease compared to the general population. The purpose of the present study was to determine the frequency of thyroid antibodies in children referred to a pediatric rheumatology center for a positive ANA without evidence of a connective tissue disease.</p> <p>Methods</p> <p>A retrospective chart review was performed on children who were referred to our pediatric rheumatology center between August 2003 and March 2007 for positive ANA with concurrent thyroid antibody and thyroid function tests performed who did not fulfill criteria for a specific connective tissue disease. Laboratory and clinical features were recorded and analyzed. Mean and standard deviation were used to describe continuous data. Chi-square or Fisher's exact tests were used to compare proportions between variables.</p> <p>Results</p> <p>One-hundred and four ANA-positive patients with concurrent thyroid studies were evaluated (88% female, 93% Caucasian, mean age 11.9 Ā± 4.0 years). Half of patients had an ANA titer ā„ 1:320. The ANA pattern was speckled in 60% of the patients. Thyroid antibodies were detected in 30% of the patients. Anti-Thyroglobulin (ATG) was detected in 29% and Anti-thyroid peroxidase (ATPO) in 21% of the patients; of these children, 14% had hypothyroidism. ANA pattern and titer were not associated with anti-thyroid antibody positivity.</p> <p>Conclusion</p> <p>Thyroid antibodies associated with chronic lymphocytic thyroiditis, ATG and ATPO, were detected significantly higher in ANA-positive children without a rheumatologic condition (30%) as compared to the general pediatric population (1.3 - 3.4%). ANA titer and pattern did not help predict the presence or absence of thyroid antibodies. Given the high frequency of thyroid antibodies and increased risk of developing hypothyroidism over time, routine evaluation of ATG and ATPO with thyroid function tests in ANA-positive children is recommended.</p
