Outbreak of autochthonous canine visceral leishmaniasis in Santa Catarina, Brazil

The present study reports the first outbreak of autochthonous canine visceral leishmaniasis in Florianópolis, Santa Catarina, southern Brazil. Following the report of two cases of CVL, the Control Center of Zoonotic Diseases conducted a serological survey by ELISA and IFAT assays in seven districts of the Santa Catarina Island. Eleven seropositive dogs of autochthonous transmission were used in the present study. Infection by Leishmania sp. was confirmed by parasitological examination of bone marrow, liver, spleen and lymph nodes, culture in Schneider's medium and PCR. Leishmania sp. isolates were characterized by PCR-RFLP and hybridization with specific probes, allowing for the identification of Leishmania infantum. Autochthonous transmission of this disease in an area with high tourist traffic presents a major public health concern and signifies the emergence of an important zoonosis in southern Brazil. Therefore, the implementation of surveillance and control measures is imperative to prevent the spread of the disease among the canine population as well as transmission to the human population.

Welland County Records, 1961-1989

The origins of the Welland County Fair date back to the founding of the County of Welland in 1852. A provincial charter was issued in 1853 to create the Welland County Agricultural Society that was to operate the Fair. In 1970, the Welland County Fair became the Niagara Regional Exhibition, and the Society became known as the Niagara Regional Agriculture Society. The Society seeks to “encourage interest, promote improvements in and advance the standards of agriculture, domestic industry and rural life”. The Welland Festival of Arts was developed in 1986 in order to revitalize the town’s economy. An “outdoor art gallery” was created by painting murals on buildings that depicted the town’s heritage, a concept successfully adopted by the town of Chemainus, B.C. The first mural was completed in the summer of 1988, and by 1991 there were a total of 28 murals around the city. The endeavour proved successful: in the years that followed the creation of the Festival, two new hotels were constructed, a third was expanded, and there was an addition to the Seaway Mall to accommodate the increased tourist traffic. Optimist International is a non-profit organization that strives to “bring out the best in kids” . The first Canadian club was formed in Toronto in 1924. The Welland branch of the Optimist Club was founded in 1937. The first Welland County General Hospital opened in 1908. As the population increased, it became necessary to expand the existing facilities. Additions were made to the original structure with an East wing in 1930 and a children’s ward in 1931. However, in the 1950’s, the hospital was operating beyond optimum capacity and the need for a larger facility was clear. It was decided that a new hospital would be built, which opened in April 1960. The new hospital had 259 beds and 51 bassinets. Further additions were made in 1967 and 1978. The County of Welland was formed in 1850 when it was officially separated from Lincoln County, however, the two counties continued to operate together until 1856 when a new County building and jail for Welland County were completed. That same year, the first meeting of the Council of the Corporation of Welland County took place. The final meeting of the Council took place on December 18, 1969. The following year, the County of Welland merged with Lincoln County to form the Regional Municipality of Niagara. The Welland Mills in Thorold, Ont., was built in 1846-1847 by Jacob Keefer and is thought to have been one of the largest flour mills in Upper Canada. Ownership of the mill changed several times over the years and previous owners include the Howland family, the Hedley Shaw Milling Company and the Maple Leaf Milling Company. In 1986, the building received a heritage plaque from the Ontario Heritage Foundation, an agency of the Ontario Ministry of Culture and Recreation. At this time, the mill was no longer in operation and was being used for storage by Fraser, Inc. By 2006, the dilapidated building had been redeveloped into18 apartments and 2 floors of commercial space, while maintaining many heritage features. The building is currently known as the Welland Mills Centre.

Fast-Food Franchises: An Alternative Menu for Hotel/Casinos

In their discussion - Fast-Food Franchises: An Alternative Menu for Hotel/Casinos - by Skip Swerdlow, Assistant Professor of Finance, Larry Strate, Assistant Professor of Business Law, and Francis X. Brown, Assistant Professor of Hotel Administration at the University of Nevada, Las Vegas, their preview reads: Hotel/casino food service operations are adding some non-traditional fare to their daily offerings in the form of fast-food franchises. The authors review aspects of franchising and cite some new Las Vegas food ideas.” The authors offer that the statewide food and beverage figures, according to the Nevada Gaming Abstract of 1985, exceeded $1.24 billion. Most of that figure was generated in traditional coffee shops, gourmet dining rooms, and buffets. With that kind of food and beverage figure solidly on the table, it was inevitable that fast-food franchises would move into casinos to garner a share of the proceeds. In a March 1986 review of franchising, Restaurant Business reported the following statistics: “Over 60 percent of all restaurants are franchisee owned. This relationship is also paralleled in dollar sales, which has exceeded $53 billion.” “Restaurant franchising expansion has grown at an annual rate of 12 percent per year for the past five years.” The beginning of the article is dedicated to describing, in general, the franchise phenomenon; growth has been spectacular the authors inform you. “The franchise concept has provided an easy method of going into business for the entrepreneur with minimal business experience, but a desire to work hard to make a profit,” say professors Swerdlow, Strate, and Brown. Lured by tourist traffic, and the floundering Chapter 11 afflicted, Riviera Hotel and Casino in Las Vegas, Burger King saw an attractive opportunity for an experiment in non-traditional outlet placement, say the authors. Although innately transient, the tourist numbers were way too significant to ignore. That tourist traffic, the authors say, is ‘round-the-clock. Added to that figure is the 2000-3000 average employee count for many of the casinos on the ‘Vegas strip. Not surprisingly, the project began to look very appealing to both Burger King and the Riviera Hotel/Casino, the authors report. In the final analysis, the project did work out well; very well indeed. So it is written, “The successful operation of the Burger King in the Riviera has sparked interest by other existing hotel/casino operations and fast-food restaurant chains. Burger King's operation, like so many other industry leadership decisions, provides impetus for healthy competition in a market that is burgeoning not only because of expansion that recognizes traditional population growth, but because of bold moves that search for customers in non-traditional areas.” The authors provide an Appendix listing Las Vegas hotel/casino properties and the restaurants they contain.

International tourism : can it contribute to Nigeria's economic growth as other industrial sectors?

The growth of international tourism and the attendant economic benefits to the world nations, has been phenominal since the end of the second world war. It is considered that the industry's upsurge will continue even in the phase of various constraints exemplified in high fuel cost, constant increase in fares and the threatening world-wide recessions. Developed as well as developing countries have gained substantially from the industry. A recent development shows increasing tourist traffic towards developing countries, while developed countries still hold their fort in stable growth of tourist receipts. The strategic beneficial effects of international tourist industry are often quantified in terms of foreign exchange earnings, employments offered, and the Real Estate super-structures; but in general,the industry has innumerable direct and indirect benefits to any nation engaging in the trade. The objective of this thesis is to demonstrate by comparative analysis and proven parameters that the international tourist industry which is given low priority in development in Nigeria, can equally contribute to the nation's economic growth as other industrial sectors which receive high priority and patronage in development. The data for this paper are gathered from primary sources which are i) responses by the Federal and State Governments' tourism-related offices; ii) government publications e.a. the Third National Development Plan of Federal Republic of Nigeria; and iii) Books and collections. The secondary sources include reports,periodicals and hospitality industry publications. To formally establish the international tourist industry in Nigeria, all the governments (Federal, State and Local) and the private sector in the country, should commence the development of the industry with research and feasibility studies, to be followed by proper planning at all levels and based on the result of the research and feasibility studies.

Traffic-Related Air Pollution and Perinatal Mortality: A Case-Control Study

BACKGROUND: Ambient levels of air pollution may affect the health of children, as indicated by studies of infant and perinatal mortality. Scientific evidence has also correlated low birth weight and preterm birth, which are important determinants of perinatal death, with air pollution. However, most of these studies used ambient concentrations measured at monitoring sites, which may not consider differential exposure to pollutants found at elevated concentrations near heavy-traffic roadways. OBJECTIVES: Our goal was to examine the association between traffic-related pollution and perinatal mortality. METHODS: We used the information collected for a case-control study conducted in 14 districts in the City of Sao Paulo, Brazil, regarding risk factors for perinatal deaths. We geocoded the residential addresses of cases (fetal and early neonatal deaths) and controls (children who survived the 28th day of life) and calculated a distance-weighted traffic density (DWTD) measure considering all roads contained in a buffer surrounding these homes. RESULTS: Logistic regression revealed a gradient of increasing risk of early neonatal death with higher exposure to traffic-related air pollution. Mothers exposed to the highest quartile of the DWTD compared with those less exposed exhibited approximately 50% increased risk (adjusted odds ratio = 1.47; 95% confidence interval, 0.67-3.19). Associations for fetal mortality were less consistent. CONCLUSIONS: These results suggest that motor vehicle exhaust exposures may be a risk factor for perinatal mortality.

Characterization of Yeast Extracellular Vesicles: Evidence for the Participation of Different Pathways of Cellular Traffic in Vesicle Biogenesis

Background: Extracellular vesicles in yeast cells are involved in the molecular traffic across the cell wall. In yeast pathogens, these vesicles have been implicated in the transport of proteins, lipids, polysaccharide and pigments to the extracellular space. Cellular pathways required for the biogenesis of yeast extracellular vesicles are largely unknown. Methodology/Principal Findings: We characterized extracellular vesicle production in wild type (WT) and mutant strains of the model yeast Saccharomyces cerevisiae using transmission electron microscopy in combination with light scattering analysis, lipid extraction and proteomics. WT cells and mutants with defective expression of Sec4p, a secretory vesicle-associated Rab GTPase essential for Golgi-derived exocytosis, or Snf7p, which is involved in multivesicular body (MVB) formation, were analyzed in parallel. Bilayered vesicles with diameters at the 100-300 nm range were found in extracellular fractions from yeast cultures. Proteomic analysis of vesicular fractions from the cells aforementioned and additional mutants with defects in conventional secretion pathways (sec1-1, fusion of Golgi-derived exocytic vesicles with the plasma membrane; bos1-1, vesicle targeting to the Golgi complex) or MVB functionality (vps23, late endosomal trafficking) revealed a complex and interrelated protein collection. Semi-quantitative analysis of protein abundance revealed that mutations in both MVB- and Golgi-derived pathways affected the composition of yeast extracellular vesicles, but none abrogated vesicle production. Lipid analysis revealed that mutants with defects in Golgi-related components of the secretory pathway had slower vesicle release kinetics, as inferred from intracellular accumulation of sterols and reduced detection of these lipids in vesicle fractions in comparison with WT cells. Conclusions/Significance: Our results suggest that both conventional and unconventional pathways of secretion are required for biogenesis of extracellular vesicles, which demonstrate the complexity of this process in the biology of yeast cells.

Connection Admission Control for a WDM Optical Network Based on Traffic Monitoring and Bandwidth Release

We proposed a connection admission control (CAC) to monitor the traffic in a multi-rate WDM optical network. The CAC searches for the shortest path connecting source and destination nodes, assigns wavelengths with enough bandwidth to serve the requests, supervises the traffic in the most required nodes, and if needed activates a reserved wavelength to release bandwidth according to traffic demand. We used a scale-free network topology, which includes highly connected nodes ( hubs), to enhance the monitoring procedure. Numerical results obtained from computational simulations show improved network performance evaluated in terms of blocking probability.

Performance analysis of an optical network employing waveband and traffic grooming

This paper analyses an optical network architecture composed by an arrangement of nodes equipped with multi-granular optical cross-connects (MG-OXCs) in addition to the usual optical cross-connects (OXCs). Then, selected network nodes can perform both waveband as well as traffic grooming operations and our goal is to assess the improvement on network performance brought by these additional capabilities. Specifically, the influence of the MG-OXC multi-granularity on the blocking probability is evaluated for 16 classes of service over a network based on the NSFNet topology. A mechanism of fairness in bandwidth capacity is also added to the connection admission control to manage the blocking probabilities of all kind of bandwidth requirements. Comprehensive computational simulation are carried out to compare eight distinct node architectures, showing that an adequate combination of waveband and single-wavelength ports of the MG-OXCs and OXCs allow a more efficient operation of a WDM optical network carrying multi-rate traffic.

A safety assessment methodology applied to CNS/ATM-based air traffic control system

In the last decades, the air traffic system has been changing to adapt itself to new social demands, mainly the safe growth of worldwide traffic capacity. Those changes are ruled by the Communication, Navigation, Surveillance/Air Traffic Management (CNS/ATM) paradigm, based on digital communication technologies (mainly satellites) as a way of improving communication, surveillance, navigation and air traffic management services. However, CNS/ATM poses new challenges and needs, mainly related to the safety assessment process. In face of these new challenges, and considering the main characteristics of the CNS/ATM, a methodology is proposed at this work by combining ""absolute"" and ""relative"" safety assessment methods adopted by the International Civil Aviation Organization (ICAO) in ICAO Doc.9689 [14], using Fluid Stochastic Petri Nets (FSPN) as the modeling formalism, and compares the safety metrics estimated from the simulation of both the proposed (in analysis) and the legacy system models. To demonstrate its usefulness, the proposed methodology was applied to the ""Automatic Dependent Surveillance-Broadcasting"" (ADS-B) based air traffic control system. As conclusions, the proposed methodology assured to assess CNS/ATM system safety properties, in which FSPN formalism provides important modeling capabilities, and discrete event simulation allowing the estimation of the desired safety metric.

Glow worms as a tourist attraction in Springbrook National Park: Visitor attitudes and economic issues

nsect-based tourism mainly caters to a niche market, but its popularity has been growing in recent years. Despite its popularity this form of tourism has remained under-researched and in a sense its contribution to the tourism industry has gone mostly unnoticed. This paper reports the results of a study undertaken on one form of popular insect-based tourism, namely glow worms. The study was undertaken in Springbrook National Park (Natural Bridge section) southeast Queensland, which has one of the largest glow worm colonies in Australia that attracts thousands of visitors each year. A study of this form of tourism is important and useful for several reasons. It is important to understand this hitherto under-studied tourism activity to determine the type of visitors, their socio-economic attributes, economic benefits to the local economy, visitors’ knowledge of glow worms, education imparted, visitor satisfaction of glow worm viewing and visitor attitudes for the introduction of a user fee system to view glow worms. An understanding of these issues could not only help to better manage this valuable biological resource, but can be used to develop the industry to cater to a growing number of visitors. Tourism in glow worms can potentially be used not only to educate the public on the threats affecting glow worms and their colonies, but could also be used to conserve them. Lessons learnt from glow worms as an attraction to Springbrook National Park can be used to better manage and further develop other existing and new glow worm sites in Australia and elsewhere for tourism. Furthermore, it could provide some guidance for the management and development of other forms of current insect-based tourism activities (eg. butterflies) and develop new tourism ventures based on species such as stick insects and jewel beetles for which Australia is well known (Reader’s Digest, 1997)

An object-oriented neural network approach to short-term traffic forecasting

This paper discusses an object-oriented neural network model that was developed for predicting short-term traffic conditions on a section of the Pacific Highway between Brisbane and the Gold Coast in Queensland, Australia. The feasibility of this approach is demonstrated through a time-lag recurrent network (TLRN) which was developed for predicting speed data up to 15 minutes into the future. The results obtained indicate that the TLRN is capable of predicting speed up to 5 minutes into the future with a high degree of accuracy (90-94%). Similar models, which were developed for predicting freeway travel times on the same facility, were successful in predicting travel times up to 15 minutes into the future with a similar degree of accuracy (93-95%). These results represent substantial improvements on conventional model performance and clearly demonstrate the feasibility of using the object-oriented approach for short-term traffic prediction.
