Tourism in Dubai: overcoming barriers to destination development

INTERNATIONAL JOURNAL OF TOURISM RESEARCH, Issue 2 2006
Joan C. Henderson
Abstract The Middle East as a whole attracts comparatively few visitors, and political events in the current century have generated new uncertainties and tensions which seem likely to further discourage tourists and investors. Additional barriers relate to poor accessibility, a perceived lack of conventional attractions and limited promotion. Despite these apparently unfavourable circumstances, international tourism has been adopted by the Dubai authorities as a core element in a programme of economic diversification. They have invested heavily in expensive facilities, as well as undertaken extensive marketing, and the outcome has been strong growth in tourism. There are great expectations of the future, reflected in the setting of very high arrival targets. However, there are also several constraints that might inhibit progress, with a need to review strategies. The experience of Dubai thus serves to illustrate factors that are critical to destination development, major impediments and approaches to overcoming these. Copyright © 2006 John Wiley &Sons, Ltd.

Barriers to Caregiver Compliance with Eating and Drinking Recommendations for Adults with Intellectual Disabilities and Dysphagia

JOURNAL OF APPLIED RESEARCH IN INTELLECTUAL DISABILITIES, Issue 2 2006
Darren D. Chadwick
Background, There is scant research on the subject of dysphagia and people with intellectual disabilities. This study explores the barriers which caregivers believe make following Speech and Language Therapists' (SLTs) dysphagia management strategies more difficult. Method, Semi-structured open-ended interviews were conducted with 46 caregivers who supported 40 intellectually disabled adults with dysphagia. Results, Caregivers perceived particular difficulties in modifying food and drinks to safe consistencies, achieving the agreed positioning during mealtimes, and in using support and prompting strategies. Problematic support and prompting strategies included difficulties with pacing correctly; facilitating people to adequately relax and concentrate; observing and prompting people to pace suitably and take safe amounts of food and drink in each mouthful. Additional barriers identified included time pressures, staff turnover and insufficient reviewing of SLT management strategies by caregivers. Conclusions, Findings suggest that additional training and monitoring is required to ensure caregivers are aware of their role and responsibility in promoting safe oral intake for adults with dysphagia and intellectual disabilities. Ongoing support is suggested for people with intellectual disabilities and dysphagia to help them understand the reasoning behind management strategies. [source]


EFFECT OF HEADSPACE OXYGEN AND FILMS OF DIFFERENT OXYGEN TRANSMISSION RATE ON TOXIN PRODUCTION BY CLOSTRIDIUM BOTULINUM TYPE E IN RAINBOW TROUT FILLETS STORED UNDER MODIFIED ATMOSPHERES

JOURNAL OF FOOD SAFETY, Issue 3 2000
ISABELLE DUFRESNE
ABSTRACT Studies were conducted to determine the effect of various levels of headspace oxygen (0,100%, balance CO2) or film oxygen transmission rate (OTR) on the time to toxicity in modified atmosphere packaged (MAP) fresh trout fillets challenged with C. botulinum type E (102 spore/g) and stored under moderate temperature abuse conditions (12C). In all cases, trout were toxic within 5 days, irrespective of the initial levels of oxygen in the package headspace. However, spoilage preceded toxigenesis. Packaging of trout fillets in low gas barrier films, with OTRs ranging from 4,000 to 10,000 cc/m2/day at 24C and 0% relative humidity, also had no effect on time to toxicity in all MAP trout fillets. All fillets were toxic within 4,5 days and spoilage again preceded toxigenesis. This study has shown that the addition of headspace O2, either directly to a package or indirectly by using a low gas barrier film, had no influence on the time to toxigenesis or spoilage. Additional barriers, other than headspace O2 or film transmission rate, need to be considered to ensure the safety of MAP trout fillets, particularty at moderate temperature abuse conditions.

EFFECT OF ETHANOL VAPOR ON GROWTH AND TOXIN PRODUCTION BY CLOSTRIDIUM BOTULINUM IN A HIGH MOISTURE BAKERY PRODUCT

JOURNAL OF FOOD SAFETY, Issue 2 2000
DAPHNE PHILLIPS DAIFAS
ABSTRACT To determine the effect of ethanol vapor on toxin production by Clostridium botulinum, studies were done in English style crumpets (aw 0.990, pH 6.5) challenged with 500 spores/g C. botulinum types A and proteolytic B and packaged in high gas barrier bags [ethanol transmission rate (ETR) 0.21 g/m2/day @ 25 C]. Crumpets were packaged in air with either commercially available ethanol vapor generators (Ethicap® 2, 4 or 6G) or cotton wool pads saturated with 2, 4 or 6 g of 95% food grade ethanol and stored at 25C. Toxin was detected in all inoculated control crumpets (0% ethanol) after 5 days at ambient temperature (25C). Ethicap® 2G delayed toxicity for 10 days while complete inhibition (>21 days) was observed in all crumpets packaged with 4 or 6G Ethicap® or with 2, 4 or 6 g of ethanol per pad. However, all crumpets were overtly spoiled by this time. Both headspace ethanol and absorption of ethanol by crumpets increased as a function of Ethicap® size/weight of ethanol. Based on these preliminary studies, ethanol vapor would appear to be an effective additional barrier to control the growth and toxin production by C. botulinum in high moisture bakery products and ensure the safety of these products at ambient temperature.

Identifying and overcoming the potential barriers to the adoption of natural orifice transluminal endoscopic surgery

ASIAN JOURNAL OF ENDOSCOPIC SURGERY, Issue 2 2010
S. D. Schwaitzberg
Abstract Natural orifice translumenal endoscopic surgery (NOTES) is an emerging innovative approach to performing minimally invasive surgical procedures. In its full potential, the concept of incisionless surgery will have mass appeal to patients. However, the barriers to adopting NOTES will have to be overcome before widespread acceptance of these techniques can occur. These potential barriers include infection, visceral leakage, difficulties in tissue manipulation, and increased cost. The history of surgical innovation has continuously overcome similar problems in other settings, and all of these potential obstacles are likely solvable. Training surgeons will be an additional barrier that will need to be overcome, but this obstacle will need to be approached differently than when laparoscopy was introduced, as standards are higher today for privileging and credentialing in most hospitals than 20 years ago. Alternative technologies that were not adopted prior to the introduction of NOTES may now appear more viable making the competitive environment more complex. Increased funding for comparative effectiveness studies and training for competency in innovation will also need original solutions, but are clearly in our patients' best interest. [source]


Multiple barriers to gene exchange in a field cricket hybrid zone

BIOLOGICAL JOURNAL OF THE LINNEAN SOCIETY, Issue 2 2009
LUANA S. MAROJA
Data on patterns of variation within hybrid zones, combined with studies of life history, mate choice, and hybrid performance, allow estimates of the contribution of different pre-zygotic and post-zygotic barriers to reproductive isolation. We examine the role of behavioural barriers to gene exchange in the maintenance of a hybrid zone between North American field crickets Gryllus firmus and Gryllus pennsylvanicus. We consider these barriers in the context of previous studies that documented temporal and ecological isolation and a one-way post-mating incompatibility (i.e. G. firmus females do not produce offspring when they mate only with heterospecific males). Based on no-choice mating experiments in the laboratory, we demonstrate strong behavioural pre-mating barriers between the two species, but no apparent fecundity or fertility costs for G. firmus females when they mate with both conspecific and heterospecific males. Furthermore, we show that G. firmus females do not discriminate between hybrids and conspecifics, whereas G. pennsylvanicus females do. This observation could explain the asymmetric allele introgression observed in the hybrid zone. We also document a failure of heterospecific males to induce normal oviposition in G. firmus females, which may be due to rapid evolution of accessory gland proteins and may serve as an additional barrier to gene exchange. © 2009 The Linnean Society of London, Biological Journal of the Linnean Society, 2009, 97, 390,402.

Mainstreaming Risk Reduction in Urban Planning and Housing: A Challenge for International Aid Organisations

DISASTERS, Issue 2 2006
Christine Wamsler
Abstract The effects of ,natural' disasters in cities can be worse than in other environments, with poor and marginalised urban communities in the developing world being most at risk. To avoid post-disaster destruction and the forced eviction of these communities, proactive and preventive urban planning, including housing, is required. This paper examines current perceptions and practices within international aid organisations regarding the existing and potential roles of urban planning as a tool for reducing disaster risk. It reveals that urban planning confronts many of the generic challenges to mainstreaming risk reduction in development planning. However, it faces additional barriers. The main reasons for the identified lack of integration of urban planning and risk reduction are, first, the marginal position of both fields within international aid organisations, and second, an incompatibility between the respective professional disciplines. To achieve better integration, a conceptual shift from conventional to non-traditional urban planning is proposed. This paper suggests related operative measures and initiatives to achieve this change. [source]


RESEARCH AND EVALUATION: The Rudd Government's Employment Services Agenda: Is it Post-NPM and Why is that Important?

AUSTRALIAN JOURNAL OF PUBLIC ADMINISTRATION, Issue 3 2010
Gaby Ramia
Perhaps the most potent symbol of the Howard government's faith in New Public Management (NPM) was the Job Network. Interrogating the Rudd government's replacement package, this article assesses whether the recent restructuring of employment services constitutes a post-NPM environment. It is argued that there are major post-NPM elements, seen most clearly in: the softening of jobseeker sanctions; greater deliberation on policy direction and results; a more inclusive employment super-ministry and reliance on other ,horizontal' governance reforms; and enhanced government resources for multiple-disadvantage clients. However, categorising these changes as post-NPM is problematic because the steering mechanism remains the market-based contract, a central NPM characteristic. Theoretical difficulties in applying paradigmatic concepts to services provide additional barriers to conclusive assessments, though the Rudd government's employment services regime provides a basis for taking stock in the post-NPM debate.
