The tourist experience of heritage urban spaces : Valletta as a case study

This article provides an understanding of how tourists experience heritage urban spaces by investigating features that influence tourist experiences most. It is framed within urban design literature which refers to three elements of urban space namely physical setting (or form), activity, and meaning. These elements are used to explore how urban spaces are experienced by tourists. Its findings are derived from an in-depth qualitative analysis of interviews with tourists to Valletta, Malta. The research suggests that the intrinsic qualities of the space are relevant to the tourist experience but what is even more relevant are the interactions of the tourist with different elements within that space, namely interactions with surroundings, interactions with others, and interactions with self/meaning. Within this broad conceptual model, the research identifies important sub-themes. Some of these reinforce the findings of existing work on tourist experiences, but others are often under-estimated or neglected.peer-reviewe

Microlens Parallax Measurements with a Warm Spitzer

Because Spitzer is an Earth-trailing orbit, losing about 0.1 AU/yr, it is excellently located to perform microlens parallax observations toward the Magellanic Clouds (LMC/SMC) and the Galactic bulge. These yield the so-called ``projected velocity'' of the lens, which can distinguish statistically among different populations. A few such measurements toward the LMC/SMC would reveal the nature of the lenses being detected in this direction (dark halo objects, or ordinary LMC/SMC stars). Cool Spitzer has already made one such measurement of a (rare) bright red-clump source, but warm (presumably less oversubscribed) Spitzer could devote the extra time required to obtain microlens parallaxes for the more common, but fainter, turnoff sources. Warm Spitzer could observe bulge microlenses for 38 days per year, which would permit up to 24 microlens parallaxes per year. This would yield interesting information on the disk mass function, particularly old brown dwarfs, which at present are inaccessible by other techniques. Target-of-Opportunity (TOO) observations should be divided into RTOO/DTOO, i.e., ``regular'' and ``disruptive'' TOOs, as pioneered by the Space Interferometry Mission (SIM). LMC/SMC parallax measurements would be DTOO, but bulge measurements would be RTOO, i.e., they could be scheduled in advance, without knowing exactly which star was to be observed.Comment: 6 pages + 1 Figure, To be presented at The Warm Spitzer Mission Workshop, 4-5 June 2007, Pasaden

Hydrometeor development in cold clouds in FIRE

The role of cirrus clouds, particularly in weather and climate processes, has been increasingly investigated. Numerical models have demonstrated the importance of the solar reflectivity and infrared radiation of cirrus clouds in the Earth's radiation budget and climate. These properties depend upon the cloud microphysical characteristics, density, and altitude and hence justify investigation. The results reported were obtained from cold clouds (-20 to -46 C) in the mid to upper troposphere during ten flights of the NCAR King Air as part of the First ISCCP Research Experiment (FIRE) in Wisconsin

Lidar and aircraft studies of deep Cirrus systems from the 1986 FIRE IFO

Several NCAR King Air flight missions were conducted during the Wisconsin FIRE IFO experiment in support of the University of Utah polarization lidar observations of deep cirrus cloud systems at the Wausau ground site. Data collected from four cirrus systems are included in this analysis, including those of 22 and 28 October, and 1 and 2 November. Lidar data were generally obtained at 2 min intervals in the zenith direction over observation periods that ranged from approximately 4 to 10 h, bracketing the aircraft missions. The data were processed to yield height-time (HTI) displays of lidar linear depolarization ratio sigma and relative range-normalized return power P. King Air operations consisted of a combination of rapid profiling and Lagrangian spiral descents and stacked racetrack patterns in the vicinity of the field site. From the spiral descents are constructed vertical profiles of ice particle concentration N(sub i) and ice mass content IWC derived from PMS 2-D probe imagery and, when detected, FSSP cloud droplet concentration N(sub W) and liquid water content, LWC. Aircraft flight leg data are presented for the vertical velocity W and the same ice and water cloud content parameters. In addition, aerosol particle concentrations obtained with the ASAS probe are examined, and photographs of ice particles collected in-situ on oil-coated slides are presented to illustrate ice particle habit

A 45-year-old Female with an Atypical Presentation of Pharyngitis

Introduction: Emergency physicians are trained to treat a variety of ailments in the emergency department (ED), some of which are emergent, while others are not. A common complaint seen in the ED is a sore throat. While most sore throats are easily diagnosed and treated, less common causes are often not considered in the differential diagnoses. Therefore, the purpose of this case study was to present an atypical case of sore throat and discuss differential diagnoses.Case Presentation: The patient was a 45-year-old female who presented to the ED with a three-day history of sore throat that was exacerbated by eating and drinking. The patient was not on any prescription medications, but tried over-the-counter medications for the sore throat without any improvement in symptoms. Review of systems was positive for sore throat, fevers, and chills. Physical examination of her oropharynx revealed mildly dry mucous membranes with confluent plaques and white patchy ulcerative appearance involving the tongue, tonsils, hard palate, and soft palate. Rapid streptococcal antigen, mononucleosis spot test, and KOH test were performed and found to be negative.Discussion: After initial testing was negative, a follow-up complete blood count with differential and complete metabolic profile were ordered. The patient was found to have decreased lymphocytes and platelets. Based upon those results, a diagnosis was made in the ED, the patient was started on medication, and further laboratory workup was ordered to confirm the diagnosis. ED providers should consider non-infectious as well as infectious causes for a sore throat, as this might lead to a diagnosis of an underlying condition

Retrospective Evaluation of Clinical Experience With Intravenous Ascorbic Acid in Patients With Cancer.

BACKGROUND: Intravenous ascorbic acid (IV AA) has been used extensively in cancer patients throughout the United States. Currently, there are limited data on the safety and clinical effects of IV AA. The purpose of this study was to expand the current literature using a retrospective analysis of adverse events and symptomatic changes of IV AA in a large sample of cancer patients. METHODS: We conducted a retrospective chart review of all patients receiving IV AA for cancer at the Thomas Jefferson University Hospital over a 7-year period. We assessed all reports of adverse events, laboratory findings, and hospital or emergency department admissions. We also reviewed quality-of-life data, including fatigue, nausea, pain, appetite, and mood. RESULTS: There were 86 patients who received a total of 3034 doses of IV AA ranging from 50 to 150g. In all, 32 patients received only ascorbic acid as part of their cancer management (1197 doses), whereas 54 patients received ascorbic acid in conjunction with chemotherapy (1837 doses). The most common adverse events related to ascorbic acid were temporary nausea and discomfort at the injection site. All events reported in the ascorbic acid alone group were associated with less than 3% of the total number of infusions. Patients, overall, reported improvements in fatigue, pain, and mood while receiving ascorbic acid. CONCLUSIONS: The results of this retrospective analysis support the growing evidence that IV AA is generally safe and well tolerated in patients with cancer, and may be useful in symptom management and improving quality of life

Editorial: Watching My Mother Die - Subjectivity and the Other Side of Dementia

In this editorial, the authors discuss the idea of subjectivity as an often levelled criticism of qualitative reasearch, challenging the binary divide between subjective and objective. As an example of what could be "accused" of being a subjective account, Moules then discusses her experience of being at the other end of her mother's recent encounter with dementia

Demographic, Economic, and Social Transformations in Bronx Community District 9: Parkchester, Unionport, Soundview, Castle Hill, and Clason Point, 1990 - 2006

Introduction: This report analyzes demographic and socioeconomic characteristics among the five largest Latino nationality groups during 1990-2006 in the NYC Community District 9 of the borough of the Bronx, which comprises the neighborhoods of Parkchester, Unionport, Soundview, Castle Hill, and Clason Point. Methods: Data on Latinos and other racial/ethnic groups were obtained from the U.S. Census Bureau American Community Survey, reorganized for public use by the Minnesota Population Center, University of Minnesota, IPUMSusa. Cases in the dataset were weighted and analyzed to produce population estimates. Results: Puerto Ricans are the largest Latino subgroup in the Bronx Community District 9, accounting for over 32% of the total population and 75% of the Latino population in the district. Latinos in the Bronx Community District 9, as a group, tend to be younger than non-Hispanic Whites and non-Hispanic Blacks. Among the major racial/ethnic groups, Latinos have the second lowest homeownership rate in the district after non-Hispanic Blacks. The annual median incomes of the majority of the residents in the Bronx Community District 9 have increased since 1990. Asians and Non-Hispanic Whites had the largest median incomes even though they represent the smallest segments of the total population in the district. Among Latinos, Ecuadorians and Guatemalans also had the largest median incomes even though they represented the smallest segments of the Latino population in Community District 9. Educational attainment levels differed significantly among the major racial/ethnic groups, with Asians achieving significantly higher educational attainment levels over Latinos, which had the lowest percentage of individuals with a Bachelor’s or higher degree. Among Latinos, Dominicans and Puerto Ricans had the highest percentage of people 25 years and older who had a B.A. or higher degree. Discussion: Bronx-based stakeholders and advocacy groups may find this report valuable when attempting to identify key trends and obstacles facing Latinos in these communities and better allocate time and resources
