Information Technology and Vacation Planning, Behavior, and Satisfaction: A Longitudinal Panel Study

With much of tourism and information technology (IT) research focused on pre-trip planning and information search, this study treats vacations as multi-phase experiences in order examine how IT is influencing the way vacations are experienced before, during, and after the vacation travel event. The longitudinal panel methodology and vacation diaries employed in this study facilitated in situ data collection across time and situations. While very few panelists indicated they would not bring any IT on vacation, 40% of vacation diarists did not access the Internet while on vacation. Results suggest those who use the Internet and other forms of information technology on vacations are just as satisfied with their vacations as those who take IT with them but don’t bother to use it. Findings show some differentiation among levels of technology adopters in terms of vacation IT behavior, specifically related to wireless technology

Governance Keeping up with Sharing Economy Innovations

The sharing economy presents new regulatory issues by raising inquiries into market innovation and government intervention. This research focuses on policy areas that have not received much attention in the current debate on the sharing economy, particularly in the tourism literature. Based on the survey on local government officials in the U.S. cities and counties (n=599), the research aims at (1) exploring stakeholder groups that are perceived to be influential in acting on legislation among policymakers and (2) examining determinants that influence legislative status with a focus on sharing economy innovations. The results indicate that legislative status is influenced by stakeholder groups who actively engaged in legislation with different objectives as well as jurisdiction characteristics such as population size and geographical region. The study offers insights into how policymakers keep up with the tremendous innovations that take place in the tourism industry

A Comparison of Tourism-Related Stressors Experienced by Residents of Three Island Destinations

Residents of island tourism destinations are subject to a variety of impacts their quality of life. One impact that has recently emerged as an issue is psychological stress. Psychological stress can often lead to negative physical and mental health outcomes. Island destinations develop along Butler’s (1980) Tourism Area Life Cycle in different ways based on geography, population, accessibility, and a variety of other variables. Oftentimes rapid development follows the creation of transportation links like a new airport or cruise port. The development of cruise ports in particular often bring rapid development with unforeseen consequences. In this study, we examine the tourism related stressors experienced by residents of three island destinations with varying levels of development and cruise tourism visitation. Thematic analysis of residents’ perceived stressors revealed that level of development and type of tourism play a role in the breadth, depth, and type of stressors perceived by residents

Comprehending the responsible tourism practices through principles of sustainability: A case of Kinabalu Park

This study initiates a research into the practices of responsible tourism in the UNESCO National Park, a place with high levels of biodiversity and value that is worthy of preservation. The responsible tourism definitions, practices and challenges emerged through an intense scrutiny of textual data, which were collected through in-depth interviews with 25 tour operators and park management. Results indicated that responsibility was constructed around the principles of sustainability, or a reification of, ecological friendliness, economical viability and sociocultural amicability in Kinabalu Park, Sabah. Finally, the paper exemplified three implication practices to boost responsible tourism development in Kinabalu Park and other similar parks

Catchment land use effects on fluxes and concentrations of organic and inorganic nitrogen in streams

We present annual downstream fluxes and spatial variation in concentrations of dissolved inorganic nitrogen (NH4+ and NO3−) and dissolved organic nitrogen (DON) in two adjacent Scottish catchments with contrasting land use (agricultural grassland vs. semi-natural moorland). Inter- and intra-catchment variation in N species and the relation to spatial differences in agricultural land use were studied by determining catchment N input through agricultural activities at the field scale and atmospheric inputs at a 25 m grid resolution. The average agricultural N input of 52 kg N ha−1 yr−1 to the grassland catchment was more than 4 times higher than the input of 12 kg N ha−1 yr−1 to the moorland catchment, supplemented by 12.3 and 8.2 kg N ha−1 yr−1 through atmospheric deposition, respectively. The grassland catchment was associated with an annual downstream total dissolved nitrogen (TDN) flux of 14.4 kg N ha−1 yr−1, which was 66% higher than the flux of 8.7 kg ha−1 yr−1 from the moorland catchment. This difference was largely due to the NO3− flux being one order of magnitude higher in the grassland catchment. Dissolved organic N fluxes were similar for the two catchments (7.0 kg ha−1 yr−1) with DON contributing 49% to the TDN flux in the grassland compared with 81% in the moorland catchment. The results highlight the importance of diffuse agricultural N inputs to stream NO3− concentrations and the importance of quantifying all the major aquatic N species for developing a better understanding of N transformations and transport in the atmosphere-soil-water system

Heterogeneity of atmospheric ammonia at the landscape scale and consequences for environmental impact assessment

We examined the consequences of the spatial heterogeneity of atmospheric ammonia (NH3) by measuring and modelling NH3 concentrations and deposition at 25 m grid resolution for a rural landscape containing intensive poultry farming, agricultural grassland, woodland and moorland. The emission pattern gave rise to a high spatial variability of modelled mean annual NH3 concentrations and dry deposition. Largest impacts were predicted for woodland patches located within the agricultural area, while larger moorland areas were at low risk, due to atmospheric dispersion, prevailing wind direction and low NH3 background. These high resolution spatial details are lost in national scale estimates at 1 km resolution due to less detailed emission input maps. The results demonstrate how the spatial arrangement of sources and sinks is critical to defining the NH3 risk to semi-natural ecosystems. These spatial relationships provide the foundation for local spatial planning approaches to reduce environmental impacts of atmospheric NH3

Linking public health agencies and hospitals for improved emergency preparedness: North Carolina's public health epidemiologist program

<p>Abstract</p> <p>Background</p> <p>In 2003, 11 public health epidemiologists were placed in North Carolina's largest hospitals to enhance communication between public health agencies and healthcare systems for improved emergency preparedness. We describe the specific services public health epidemiologists provide to local health departments, the North Carolina Division of Public Health, and the hospitals in which they are based, and assess the value of these services to stakeholders.</p> <p>Methods</p> <p>We surveyed and/or interviewed public health epidemiologists, communicable disease nurses based at local health departments, North Carolina Division of Public Health staff, and public health epidemiologists' hospital supervisors to 1) elicit the services provided by public health epidemiologists in daily practice and during emergencies and 2) examine the value of these services. Interviews were transcribed and imported into ATLAS.ti for coding and analysis. Descriptive analyses were performed on quantitative survey data.</p> <p>Results</p> <p>Public health epidemiologists conduct syndromic surveillance of community-acquired infections and potential bioterrorism events, assist local health departments and the North Carolina Division of Public Health with public health investigations, educate clinicians on diseases of public health importance, and enhance communication between hospitals and public health agencies.

Long-Term Signs of T Cell and Myeloid Cell Activation After Intestinal Transplantation With Cellular Rejections Contributing to Further Increase of CD16+ Cell Subsets

The intestine mediates a delicate balance between tolerogenic and inflammatory immune responses. The continuous pathogen encounter might also augment immune cell responses contributing to complications observed upon intestinal transplantation (ITx). We thus hypothesized that ITx patients show persistent signs of immune cell activation affecting both the adaptive and innate immune cell compartment. Information on the impact of intestinal grafts on immune cell composition, however, especially in the long-term is sparse. We here assessed activated and differentiated adaptive and innate immune subsets according to time, previous experience of cellular or antibody-mediated rejections or type of transplant after ITx applying multi-parametric flow cytometry, gene expression, serum cytokine and chemokine profiling. ITx patients showed an increase in CD16 expressing monocytes and myeloid dendritic cells (DCs) compared to healthy controls. This was even detectable in patients who were transplanted more than 10 years ago. Also, conventional CD4+ and CD8+ T cells showed persistent signs of activation counterbalanced by increased activated CCR4+ regulatory T cells. Patients with previous cellular rejections had even higher proportions of CD16+ monocytes and DCs, whereas transplanting higher donor mass with multi-visceral grafts was associated with increased T cell activation. The persistent inflammation and innate immune cell activation might contribute to unsatisfactory results after ITx

Retrospective harm benefit analysis of pre-clinical animal research for six treatment interventions

The harm benefit analysis (HBA) is the cornerstone of animal research regulation and is considered to be a key ethical safeguard for animals. The HBA involves weighing the anticipated benefits of animal research against its predicted harms to animals but there are doubts about how objective and accountable this process is.i. To explore the harms to animals involved in pre-clinical animal studies and to assess these against the benefits for humans accruing from these studies; ii. To test the feasibility of conducting this type of retrospective HBA.Data on harms were systematically extracted from a sample of pre-clinical animal studies whose clinical relevance had already been investigated by comparing systematic reviews of the animal studies with systematic reviews of human studies for the same interventions (antifibrinolytics for haemorrhage, bisphosphonates for osteoporosis, corticosteroids for brain injury, Tirilazad for stroke, antenatal corticosteroids for neonatal respiratory distress and thrombolytics for stroke). Clinical relevance was also explored in terms of current clinical practice. Harms were categorised for severity using an expert panel. The quality of the research and its impact were considered. Bateson's Cube was used to conduct the HBA.The most common assessment of animal harms by the expert panel was 'severe'. Reported use of analgesia was rare and some animals (including most neonates) endured significant procedures with no, or only light, anaesthesia reported. Some animals suffered iatrogenic harms. Many were kept alive for long periods post-experimentally but only 1% of studies reported post-operative care. A third of studies reported that some animals died prior to endpoints. All the studies were of poor quality. Having weighed the actual harms to animals against the actual clinical benefits accruing from these studies, and taking into account the quality of the research and its impact, less than 7% of the studies were permissible according to Bateson's Cube: only the moderate bisphosphonate studies appeared to minimise harms to animals whilst being associated with benefit for humans.This is the first time the accountability of the HBA has been systematically explored across a range of pre-clinical animal studies. The regulatory systems in place when these studies were conducted failed to safeguard animals from severe suffering or to ensure that only beneficial, scientifically rigorous research was conducted. Our findings indicate a pressing need to: i. review regulations, particularly those that permit animals to suffer severe harms; ii. reform the processes of prospectively assessing pre-clinical animal studies to make them fit for purpose; and iii. systematically evaluate the benefits of pre-clinical animal research to permit a more realistic assessment of its likely future benefits
