Sample records for air travel life-style

  1. Air travel, life-style, energy use and environmental impact

    Energy Technology Data Exchange (ETDEWEB)

    Krueger Nielsen, S.

    2001-09-01

    The overall aim of this project is to investigate the linkages between energy use, life style and environmental impact. As a case of study, this report investigates the future possibilities for reducing the growth in greenhouse gas emissions from commercial civil air transport, that is passenger air travel and airfreight. The season for this choice of focus is that we found that commercial civil air transport may become a relatively large energy consumer and greenhouse gas emitter in the future. For example, according to different scenarios presented by Intergovernmental Panel on Climate Change (IPCC), commercial civil air transport's fuel burn may grow by between 0,8 percent a factor of 1,6 and 16 between 1990 and 2050 and 2050. The actual growth in fuel consumption will depend on the future growth in airborne passenger travel and freight and the improvement rate for the specific fuel efficiency. As a central mid-term estimate the IPCC foresees that the fuel consumption may grow by around 3 percent per year until 2015. This report looks into the possibilities for reducing the growth in air traffic, as well as the possibilities for reducing the specific fuel consumption, to achieve an environmentally sustainable development. For commercial civil air transport the main challenge seems to lie in the strong growth rates currently envisioned by the aeronautical industry for the next decades. Like it is the case with most other types of (fossil) energy intensive activities the bulk of air traffic is currently performed in and between industrialised countries. In an environmentally sustainable World countries should aim at distributing resources evenly between the World's citizens. Therefore, on the longer term, there are tremendous challenges to be overcome. Achieving environmentally sustainable commercial civil air transport will first of all require that people living in currently industrialised countries stop travelling ever more by air each year.

    The aim of the study is to examine two issues of consumer air travel accessibility in Europe, namely flight time and ticket costs. The first part of the paper discusses the various methodological problems of creating time matrix and cost matrix of air travel. Because of problems of conceptualizing of the air travel network and the modifiable areal unit problem the analysis is conducted on several spatial levels. The smallest network consists of 15 busiest airports and the largest network has ...

  3. Life Style Assessment: So What!

    Aubry, William E.

    The construct life style was used by Alfred Adler to describe the characteristic way in which individuals act and think. Followers of his theories are now collecting evidence to support or validate his contentions. The assessment of client life styles serves: (1) to make the client aware of his misconceptions, (2) as a reference point for therapy,…

  4. Humor and creative life styles.

    2001-01-01

    This paper is based upon the writings of William James in the late 19th century, and Alfred Adler and Sigmund Freud in the 20th, enriched by the contributions of later personality and role theorists. The self is defined as the unique organization of each person; a style is the self in action. Different life styles and their components are expressed in different situations. I posit that humor and positive thinking, combined with meaning and purpose, are vital components of all constructive life styles. The knowledge of life styles cuts through diagnostic labels to reveal our universal humanity. It can be fruitfully applied to patients and nonpatients alike and, I found, for the self-understanding of therapist. The clinical application of life styles is illustrated through numerous vignettes.

  10. Coupling between air travel and climate

    2015-12-01

    The airline industry closely monitors the midlatitude jet stream for short-term planning of flight paths and arrival times. In addition to passenger safety and on-time metrics, this is due to the acute sensitivity of airline profits to fuel cost. US carriers spent US$47 billion on jet fuel in 2011, compared with a total industry operating revenue of US$192 billion. Beyond the timescale of synoptic weather, the El Niño/Southern Oscillation (ENSO), Arctic Oscillation (AO) and other modes of variability modulate the strength and position of the Aleutian low and Pacific high on interannual timescales, which influence the tendency of the exit region of the midlatitude Pacific jet stream to extend, retract and meander poleward and equatorward. The impact of global aviation on climate change has been studied for decades owing to the radiative forcing of emitted greenhouse gases, contrails and other effects. The impact of climate variability on air travel, however, has only recently come into focus, primarily in terms of turbulence. Shifting attention to flight durations, here we show that 88% of the interannual variance in domestic flight times between Hawaii and the continental US is explained by a linear combination of ENSO and the AO. Further, we extend our analysis to CMIP5 model projections to explore potential feedbacks between anthropogenic climate change and air travel.

    Dowdall, Nigel P; Evans, Anthony D; Thibeault, Claude

    2010-03-01

    The commercial airline industry in the 21st century is a global business, able to transport large numbers of people to almost any part of the world within a few hours. There has long been concern in public health circles about the potential for transmission of communicable diseases, such as TB, on board aircraft. The recent threats from novel and emerging infectious diseases including SARS and pandemic flu has facilitated unprecedented levels of cooperation between international industry representatives, regulators and public health authorities in addressing the issues of air travel and communicable disease. This paper reviews the regulatory environment, ways in which the risks are mitigated through aspects of aircraft design, opportunities for prevention by identifying individuals who may be suffering from a communicable disease prior to flight and the approach used in managing suspected cases of communicable disease on board aircraft.

  15. The cost of simplifying air travel when modeling disease spread.

    Directory of Open Access Journals (Sweden)

    Justin Lessler

    Full Text Available BACKGROUND: Air travel plays a key role in the spread of many pathogens. Modeling the long distance spread of infectious disease in these cases requires an air travel model. Highly detailed air transportation models can be over determined and computationally problematic. We compared the predictions of a simplified air transport model with those of a model of all routes and assessed the impact of differences on models of infectious disease. METHODOLOGY/PRINCIPAL FINDINGS: Using U.S. ticket data from 2007, we compared a simplified "pipe" model, in which individuals flow in and out of the air transport system based on the number of arrivals and departures from a given airport, to a fully saturated model where all routes are modeled individually. We also compared the pipe model to a "gravity" model where the probability of travel is scaled by physical distance; the gravity model did not differ significantly from the pipe model. The pipe model roughly approximated actual air travel, but tended to overestimate the number of trips between small airports and underestimate travel between major east and west coast airports. For most routes, the maximum number of false (or missed introductions of disease is small (<1 per day but for a few routes this rate is greatly underestimated by the pipe model. CONCLUSIONS/SIGNIFICANCE: If our interest is in large scale regional and national effects of disease, the simplified pipe model may be adequate. If we are interested in specific effects of interventions on particular air routes or the time for the disease to reach a particular location, a more complex point-to-point model will be more accurate. For many problems a hybrid model that independently models some frequently traveled routes may be the best choice. Regardless of the model used, the effect of simplifications and sensitivity to errors in parameter estimation should be analyzed.

  16. Controlling pandemic flu: the value of international air travel restrictions.

    Directory of Open Access Journals (Sweden)

    Joshua M Epstein

    Full Text Available BACKGROUND: Planning for a possible influenza pandemic is an extremely high priority, as social and economic effects of an unmitigated pandemic would be devastating. Mathematical models can be used to explore different scenarios and provide insight into potential costs, benefits, and effectiveness of prevention and control strategies under consideration. METHODS AND FINDINGS: A stochastic, equation-based epidemic model is used to study global transmission of pandemic flu, including the effects of travel restrictions and vaccination. Economic costs of intervention are also considered. The distribution of First Passage Times (FPT to the United States and the numbers of infected persons in metropolitan areas worldwide are studied assuming various times and locations of the initial outbreak. International air travel restrictions alone provide a small delay in FPT to the U.S. When other containment measures are applied at the source in conjunction with travel restrictions, delays could be much longer. If in addition, control measures are instituted worldwide, there is a significant reduction in cases worldwide and specifically in the U.S. However, if travel restrictions are not combined with other measures, local epidemic severity may increase, because restriction-induced delays can push local outbreaks into high epidemic season. The per annum cost to the U.S. economy of international and major domestic air passenger travel restrictions is minimal: on the order of 0.8% of Gross National Product. CONCLUSIONS: International air travel restrictions may provide a small but important delay in the spread of a pandemic, especially if other disease control measures are implemented during the afforded time. However, if other measures are not instituted, delays may worsen regional epidemics by pushing the outbreak into high epidemic season. This important interaction between policy and seasonality is only evident with a global-scale model. Since the benefit of

  19. Weather, knowledge base and life-style

    Why to main-stream curiosity for earth-science topics, thus to appraise these topics as of public interest? Namely, to influence practices how humankind's activities intersect the geosphere. How to main-stream that curiosity for earth-science topics? Namely, by weaving diverse concerns into common threads drawing on a wide range of perspectives: be it beauty or particularity of ordinary or special phenomena, evaluating hazards for or from mundane environments, or connecting the scholarly investigation with concerns of citizens at large; applying for threading traditional or modern media, arts or story-telling. Three examples: First "weather"; weather is a topic of primordial interest for most people: weather impacts on humans lives, be it for settlement, for food, for mobility, for hunting, for fishing, or for battle. It is the single earth-science topic that went "prime-time" since in the early 1950-ties the broadcasting of weather forecasts started and meteorologists present their work to the public, daily. Second "knowledge base"; earth-sciences are a relevant for modern societies' economy and value setting: earth-sciences provide insights into the evolution of live-bearing planets, the functioning of Earth's systems and the impact of humankind's activities on biogeochemical systems on Earth. These insights bear on production of goods, living conditions and individual well-being. Third "life-style"; citizen's urban culture prejudice their experiential connections: earth-sciences related phenomena are witnessed rarely, even most weather phenomena. In the past, traditional rural communities mediated their rich experiences through earth-centric story-telling. In course of the global urbanisation process this culture has given place to society-centric story-telling. Only recently anthropogenic global change triggered discussions on geoengineering, hazard mitigation, demographics, which interwoven with arts, linguistics and cultural histories offer a rich narrative

    Adapting to climate change will not be cheap: it will cost an estimated tens of billions of dollars each year. But where will the money come from? The UN climate negotiations have set up dedicated funds for the task but domestic politics have resulted in insufficient, variable and unreliable contributions from governments. An innovative adaptation levy on international air travel could help fill the gap. A small charge to individual travellers would raise up to US$10 billion a year. The levy, which follows the 'polluter pays' principle, could be implemented very quickly and at minimal cost and would go a long way to raising sums that could make a significant difference.

  6. Global sale of green air travel supported using biodiesel

    Energy Technology Data Exchange (ETDEWEB)

    Wardle, D.A. [Auckland (New Zealand)

    2003-02-01

    The technical feasibility of operating commercial aircraft on low concentration biodiesel in kerosene blends is reviewed. Although the analysis is preliminary, it seems plausible that a biodiesel component could be introduced without significant modification to aircraft, airport infrastructure, and flight operations. The use of a biodiesel component, even for only a subset of flight operations, would open the possibility of giving all passengers, the world over, regardless of route, the option to pay a premium to make their journey on 'green' fuel (actually biodiesel). In this way, the airline industry could recover the additional cost of biodiesel in comparison to kerosene. The costs associated with such a scheme are estimated, as is consumer demand. Although the analysis is preliminary, the scheme appears commercially viable. From a humanitarian and/or environmental perspective, marketing flight on biodiesel as 'green air travel' is problematic. On the one hand, the use of biodiesel in aviation would reduce addition of carbon dioxide to the atmosphere and foster development of sustainable technology. On the other hand, it would require that agricultural resources be dedicated to air travel, nominally a luxury, in a world where agricultural resources appear destined to come under increasing strain merely to satisfy humanity's basic food and energy needs. A preliminary discussion of these issues is presented. It is hoped that this can serve as the starting point for further discussion, at an international level, to reach consensus on whether marketing of flight on biodiesel as 'green air travel' should be allowed to proceed, or whether it should be declared unethical.

    For the world's poorest countries and communities, adaptation to climate change is urgently needed, but costly: estimates run into tens of billions of dollars a year. Given the shortfall in current international adaptation funding, how can resources for the developing world be raised? An adaptation levy on international air travel could help fill the gap. A small per-trip payment by passengers could contribute US$8 billion to US$10 billion a year towards adaptation. Similar schemes in France and elsewhere show that this kind of ethical solidarity and 'polluter pays' approach would be simple to implement in practical and institutional terms.

    Full Text Available This present study was intended to analyze the Life Style of the Rented Land Owners at Ubud Subdistrict. The problems of the study are formulated as follows: (1 what is the characteristic of the rented land owners at Ubud Subdistrict like? (2 How has the process of life style of the rented land owners at Ubud Subdistrict  taken place? And (3 what is the implication of the life style of the rented land owners on their lives? Qualitative method was employed in the study. The data were processed using observation, interview and documentary techniques. The workability of the law regulating the demand for land at Ubud Subdistrict motivated the land owners to rent out their land to investors. Apart from that, the internal dimension, which is made up of the economical capital, was the most important element as it could activate small, medium and big enterprises. Another aspect was image which was reflected through perception, cognition, motivation, and attitude of individuals as consumers. As an illustration, they built luxurious houses and showed off luxurious cars to show the image that they were new wealthy people. On the other hand, there was external dimension, namely, the highly rapid development of tourism, which could positively and negatively contribute to the life style of the people living at Ubud Subdistrict. Such an implication could not be avoided. The other aspect was consumerism; the consumers were around the symbol and sign. Mass media were the miracles of the object liturgy; pleasure was defined as the realization of freedom, and the human body was the main object of consumers. The last aspect was the government’s policy which determined that Ubud Subdistrict was a tourist destination. As a result, the local people had the opportunity to rent out their land which was used to expand the industry of tourism and to activate the other economic enterprises.

    Full Text Available Indroduction Life style (behavior is one of the most significant factors affecting health. Although a number of factors participate in creating behavior, family is one the most important. The goal was to analyze the life style of children without parental care. Material and methods The research was done using cross-sectional data from "Children village" in Sremska Kamenica (N=127, and a questionnaire was especially created for this purpose. Results and discussion It was established that 75% of elementary school children and 43% of high school children are physically active. The greatest health risk is smoking (only 50% of students reported never to smoke cigarettes, while 17.5% were daily smokers. The problem is greatest in high school children (43% polled are daily smokers. Alcohol consumption is less common than in the general population of the same age (10% polled drink beer and wine several times a month, while 5% drink spirits - brandy, whisky etc.. Attitudes to sports, smoking and alcohol are mainly positive, but at older age there is an increased number of children with negative attitudes. Knowledge regarding healthy diet is on a lower level comparing with general population, meals are more regular, but with less desirable food. Conclusion From the aspect of health, life style of children without parental care is characterized by risky behavior, particularly in high school children.

    Galactic cosmic rays (GCR) are of extra-solar origin consisting of high-energy hydrogen, helium, and heavy ions. The GCR are modified by physical processes as they traverse through the solar system, spacecraft shielding, atmospheres, and tissues producing copious amounts of secondary radiation including fragmentation products, neutrons, mesons, and muons. We discuss physical models and measurements relevant for estimating biological risks in space and high-altitude air travel. Ambient and internal spacecraft computational models for the International Space Station and a Mars mission are discussed. Risk assessment is traditionally based on linear addition of components. We discuss alternative models that include stochastic treatments of columnar damage by heavy ion tracks and multi-cellular damage following nuclear fragmentation in tissue.

    Building America research has shown that high-performance homes can potentially give builders an edge in the marketplace and can boost sales. But it doesn't happen automatically. It requires a tailored, easy to understand marketing campaign and sometimes a little flair. This case study highlights LifeStyle Homes’ successful marketing approach for their SunSmart home package, which has helped to boost sales for the company. SunSmart marketing includes a modified logo, weekly blog, social media, traditional advertising, website, and sales staff training. Marketing focuses on quality, durability, healthy indoor air, and energy efficiency with an emphasis on the surety of third-party verification and the scientific approach to developing the SunSmart package. With the introduction of SunSmart, LifeStyle began an early recovery, nearly doubling sales in 2010; SunSmart sales now exceed 300 homes, including more than 20 zero energy homes. Completed homes in 2014 far outpaced the national (19%) and southern census region (27%) recovery rates for the same period. As technology improves and evolves, this builder will continue to collaborate with Building America.

  13. Life style factors and acquired susceptibility to environmental disease.

    2001-10-01

    Multifactorial risk factors are responsible for many diseases. They can be broadly categorized as environmental, genetic and life style factors. Much attention has been focused on the first two categories, e.g. the identification of environmental toxicants/carcinogens and the elucidation of genetic susceptibility to disease. Life style risk factors such as aging, poor nutrition, infection and exposure to toxicants can also increase susceptibility to illnesses. These life style factors can therefore be considered to cause acquired susceptibility for increased risk for environmental disease. Among Egyptians, infection with the parasite, Schistosoma, is the primary risk factor for bladder cancer and the risk is enhanced by exposure to mutagenic chemicals. We have shown that inheritance of susceptible metabolizing genes that can increase body burden of mutagenic chemicals enhances the risk. We have also hypothesized that chronic exposure to mutagenic chemicals causes cellular abnormalities that can reduce the capacity of cells to repair DNA damage and thus increase the risk for environmental disease. We have used a challenge assay to show that cells from cigarette smokers and from populations exposed to uranium, butadiene and pesticides have abnormal DNA repair responses compared to matched controls. On the other hand, the response is normal in workers exposed to very low concentrations of butadiene and benzene, and in mothers who had children with birth defects. This suggests that exposure to high enough concentrations of certain mutagens can cause acquired susceptibility in human populations.

    The reduction of dose onboard spacecraft and aircraft by appropriate shielding measures plays an essential role in the future development of space exploration and air travel. The design of novel shielding strategies and materials may involve hydrogenous composites, as it is well known that liquid hydrogen is most effective in attenuating charged particle radiation. As precursor for a later flight experiment, the shielding properties of newly developed hydrogen-rich polymers and rare earth-doped high-density rubber were tested in various ground-based neutron and heavy ion fields and compared with aluminium and polyethylene as reference materials. Absorbed dose, average linear energy transfer and gamma-equivalent neutron absorbed dose were determined by means of LiF:Mg,Ti thermoluminescence dosemeters and CR-39 plastic nuclear track detectors. First results for samples of equal aerial density indicate that selected hydrogen-rich plastics and rare-earth-doped rubber may be more effective in attenuating cosmic rays by up to 10% compared with conventional aluminium shielding. The appropriate adaptation of shielding thicknesses may thus allow reducing the biologically relevant dose. Owing to the lower density of the plastic composites, mass savings shall result in a significant reduction of launch costs. The experiment was flown as part of the European Space Agency's Biopan-5 mission in May 2005.

    Full Text Available The public should be aware of the sudden change of life style of some people that makes their life completely different from their previous ones. All of us must be ready to face any circumstances from this manifestation in the future.  The rich, wealthy and famous should be made aware that that type of life style is not wrong, but they should also be taught how to follow a normal way of life. Proper guidance and counselling on how to live normally needs to be provided with especially designed lectures and classes. Bringing these “students” to remote villages where the poor and the disadvantaged live may help them to understand the hardships of life around them. Having a short intern period within such a community will help them further understand the real life of the majority in their country. Furthermore, if they are always taught in an environment of luxury and are never faced with a normal education system and style of life, a major problem arises: if, in the future, our country is led by such graduates, who never went through our normal education system or lived a normal style of life, how can they understand and lead the majority in our country? This paper discusses this phenomenon.

    Full Text Available The study presented in this paper examines the case of the customer adoption of an air travel innovation, namely delivering through mobile telephones electronic tickets as well as boarding passes and other related services for air travel, which may be viewed as an innovation in service delivery. The qualitative study reported here adopted Rogers’ model of perceived innovation attributes and was augmented by Bauer’s framework of perceived risk. Participants in focus groups were categorized according to their attitudes towards buying electronic tickets for air travel through mobile phones. The perceived innovation attributes were identified to be significant determinants of travelers’ adoption decisions and practices. In addition, two more dimensions (compatibility with a person’s values and previous experience with the product category were found to influence travelers’ adoption decisions, stressing the high complexity of the adoption decisions for mobile phone-based air travel service innovations. The findings have practical value for organizations in the air travel sector as well as for Global Distribution Systems (GDSs and traditional travel agents.

  20. Do pregnant women have a higher risk for venous thromboembolism following air travel?

    Full Text Available International travel has become increasingly common and accessible, and it is part of everyday life in pregnant women. Venous thromboembolism (VTE is a serious public health disorder that occurs following long-haul travel, especially after air travel. The normal pregnancy is accompanied by a state of hypercoagulability and hypofibrinolysis. Thus, it seems that pregnant women are at a higher risk of VTE following air travel, and, if they have preexisting risk factors, this risk would increase. There is limited data about travel-related VTE in pregnant women; therefore, in the present study, we tried to evaluate the pathogenesis of thrombosis, association of thrombosis and air travel, risk factors and prevention of VTE in pregnant women based on available evidences. Pregnancy is associated with a five- to 10-fold increased risk of VTE compared with nonpregnant women; however, during the postpartum period, this risk would increase to 20-80-fold. Furthermore, the risk of thrombosis is higher in individuals with preexisting risk factors, and the most common risk factor for VTE during pregnancy is a previous history of VTE. Pregnant women are at a higher risk for thrombosis compared with other women. Thus, the prevention of VTE and additional risk factors should be considered for all pregnant women who travel by plane.

    Full Text Available Background. Since the incidence of adenocarcinoma of the oesophagus is rising, the prognosis is poor, and surveillance programs are expensive and mostly cost ineffective, there is a need to increase the knowledge of risk factors in Barrett’s oesophagus and oesophageal cancer in order to be able to give attention to medical prevention and/or surveillance programs. Aim. To study if there is a correlation between the development of Barrett’s oesophagus and GOR (gastro oesophageal reflux, family history of GOR, and life style factors, such as alcohol, smoking habits, and mental stress. Methods. Fifty-five consecutively selected patients with Barrett’s oesophagus (BO examined at Linköping University Hospital’s Oesophageal Laboratory were matched by sex, age, and duration of reflux symptoms with 55 GOR patients without Barrett’s oesophagus at the Oesophageal Laboratory. The medical charts in respective groups were examined for comparison of life style factors, mental stress, medication, duration of gastroesophageal acid reflux at 24 hr-pH-metry, and incidence of antireflux surgery and of adenocarcinoma of the oesophagus (ACO. Also, potential gender differences and diagnosis of ACO were studied. Results. Mean percentage reflux time on 24 hr-pH-metry was higher for the Barrett’s oesophagus group, 18% for women and 17% for men compared to 4% for women and 4% for men in the control group (P<0.05. Family history of GOR was more frequent in Barrett’s oesophagus patients (62% than in the control group (35% (P<0.05. Male patients with Barrett’s oesophagus had medical therapy for their GOR symptoms to a higher extent (38% than male controls (65% (P<0.05. No difference was found in the number of tobacco users or former tobacco users between Barrett’s oesophagus patients and controls. Barrett’s oesophagus patients had the same level of alcohol consumption and the same average BMI as the control subjects. Female patients with Barrett

    We present a case of acute mesenteric venous thrombosis after a long distance flight in a traveller presenting with abdominal pain, diarrhoea and vomiting within 48 h of prolonged immobility situation. Venous thrombosis in the lower limbs and venous thromboembolism has been clearly associated with prolonged air travel (economy class syndrome). Thrombosis was diagnosed by computed tomography of the abdomen, and after starting anticoagulant therapy with acenocumarol, symptoms yielded completely in a few weeks. The study of thrombophilia was negative, although the existence of two first-degree relatives (mother and grandmother) with a history of venous thrombosis with a history of venous thrombosis makes it likely a situation of inherited thrombophilia. Although exceptional, mesenteric venous thrombosis should be considered in travellers with acute abdominal pain after prolonged air travel when there are thrombophilic conditions.

    A high prevalence and racial disparities in asthma and allergy have been observed in American children. This study aimed to identify risk factors for asthma and allergy among children, and their contribution to racial disparities in allergy prevalence. A population-based cross-sectional study was carried out among children aged 1-8 years in Northeast Texas 2008-2009. The health conditions, life style and home environment of 3766 children were surveyed by parental questionnaires through e.g. daycares, elementary school, and medical clinics. Among participants who indicated their ethnicity, 255 were Mexican-Americans, 178 Afro-Americans and 969 Caucasians. Afro-American children had a significantly higher prevalence of asthma and eczema. Caucasian had the highest prevalence of rhinitis. Compared to Mexican-American children, Afro-American and Caucasian children were breast fed shorter time, more often went to day care center, had pets and environmental tobacco smoke exposure at home more often. For all children, being at a day care center, being exposed to dampness and environmental tobacco smoke at home were strong risk factors for asthma and allergy. Central air conditioning system was associated with an increased prevalence of wheeze among Mexican-American children, while pets were associated with an increased risk of rhinitis among Afro-American and Caucasian children. Caucasian children were generally not healthier than relatively poor Mexican-American children. Differences in the prevalence of asthma and allergy between races cannot be explained by socioeconomic status only. Life style and home environmental exposures are important risk factors for asthma and allergy in Northeast Texas children. - Highlights: {yields} This is a general population cross-sectional study in Northeast Texas. {yields} Racial disparity of allergy cannot be explained by socioeconomic status only. {yields} Life style and home environment caused racial disparity of allergy in children

    The global spread of the influenza A(H1N1)pdm09 virus (pH1N1) associated with travelers from North America during the onset of the 2009 pandemic demonstrates the central role of international air travel in virus migration. To characterize risk factors for pH1N1 transmission during air travel, we investigated travelers and airline employees from four North American flights carrying ill travelers with confirmed pH1N1 infection. Of 392 passengers and crew identified, information was available for 290 (74%) passengers were interviewed. Overall attack rates for acute respiratory infection and influenza-like illness 1-7 days after travel were 5.2% and 2.4% respectively. Of 43 individuals that provided sera, 4 (9.3%) tested positive for pH1N1 antibodies, including 3 with serologic evidence of asymptomatic infection. Investigation of novel influenza aboard aircraft may be instructive. However, beyond the initial outbreak phase, it may compete with community-based mitigation activities, and interpretation of findings will be difficult in the context of established community transmission.

    It was the objective of this study to confirm the hypothesis that women experience an increased risk of pulmonary embolism (PE) and/or thromboembolic events after long-distance air travel. We systematically reviewed the records of all patients with confirmed pulmonary embolism after arrival at Roissy-Charles-de-Gaulle (CDG) Airport (Paris, France) during a 13-year period. The incidence of PE was calculated as a function of distance travelled and gender using Bayesian conditional probabilities obtained in part from a control population of long-distance travellers arriving in French Polynesia (Tahiti). A total of 287.6 million passengers landed at CDG airport during the study period. The proportion of male to female long-distance travellers was estimated to be 50.5% to 49.5%. Overall, 116 patients experienced PE after landing [90 females (78%), 26 males (22%)]. The estimated incidence of PE was 0.61 (0.61-0.61) cases per million passengers in females and 0.2 (0.20-0.20) in males, and reached 7.24 (7.17-7.31) and 2.35 (2.33-2.38) cases, respectively, in passengers travelling over 10,000 km. Our study strongly suggests that there is a relationship between risk of PE after air travel and gender. This relationship needs to be confirmed in order to develop the best strategy for prophylaxis.

    The present study examined effects of simulated air travel on physical performance. In a randomized crossover design, 10 physically active males completed a simulated 5-h domestic flight (DOM), 24-h simulated international travel (INT), and a control trial (CON). The mild hypoxia, seating arrangements, and activity levels typically encountered during air travel were simulated in a normobaric, hypoxic altitude room. Physical performance was assessed in the afternoon of the day before (D - 1 PM) and in the morning (D + 1 AM) and afternoon (D + 1 PM) of the day following each trial. Mood states and physiological and perceptual responses to exercise were also examined at these time points, while sleep quantity and quality were monitored throughout each condition. Sleep quantity and quality were significantly reduced during INT compared with CON and DOM (P Recovery level 1 test performance was significantly reduced at D + 1 PM following INT compared with CON and DOM (P  0.05). Compared with baseline, physiological and perceptual responses to exercise, and mood states were exacerbated following the INT trial (P < 0.05). Attenuated intermittent-sprint performance following simulated international air travel may be due to sleep disruption during travel and the subsequent exacerbated physiological and perceptual markers of fatigue.

    The framework for a model of travel demand which will be useful in predicting the total market for air travel between two cities is discussed. Variables to be used in determining the need for air transportation where none currently exists and the effect of changes in system characteristics on attracting latent demand are identified. Existing models are examined in order to provide insight into their strong points and shortcomings. Much of the existing behavioral research in travel demand is incorporated to allow the inclusion of non-economic factors, such as convenience. The model developed is characterized as a market segmentation model. This is a consequence of the strengths of disaggregation and its natural evolution to a usable aggregate formulation. The need for this approach both pedagogically and mathematically is discussed.

    The Life Style Index (LSI) was designed to assess defense mechanisms, assuming that their use is related to specific emotional states and diagnostic concepts. Aiming to further investigate the psychometric properties of the Greek version of the LSI, the aim of the present study was to investigate the relationship of specific defense mechanisms with dimensions of psychological distress and hostility features in three different populations. The sample comprised 1261 adults (410 healthy participants, 723 medical patients and 128 psychiatric patients). Along with defense mechanisms (LSI), Psychological Distress (General Health Questionnaire, GHQ-28) and Hostility features (Hostility and Direction of Hostility Questionnaire, HDHQ) were also assessed. The results showed that increased psychological distress is related with increased use of all defenses except Denial, with which psychological distress is negatively associated. Regression is constantly related with psychological distress and differentiates psychiatric patients from the other groups of participants, while Compensation and Reaction Formation are related to depressive symptomatology. In medical patients, Repression was found to increase the physical dimension of psychological distress and the social dysfunction. On the contrary,Denial was negatively associated with these dimensions of psychological distress. In the psychiatric patient and healthy participant samples, Projection plays the most detrimental role. Regarding hostility and direction of hostility, those who were found to introvert their hostility presented with higher scores in Denial, indicating that they possibly 'deny' their hostility, and the degree of the Denial was found to be negatively associated with the degree of Introverted Hostility. Those who directed their hostility towards the others, presented with higher rates of Projection, while neither Denial nor Reaction Formation seemed sufficient enough to temper the degree of Extroverted

    Full Text Available Acoustic travel time tomography is presented as a possibility for remote monitoring of near surface airtemperature and wind fields. This technique provides line-averaged effective sound speeds changing with temporally and spatially variable air temperature and wind vector. The effective sound speed is derived from the travel times of sound signals which propagate at defined paths between different acoustic sources and receivers. Starting with the travel time data a tomographic algorithm (Simultaneous Iterative Reconstruction Technique, SIRT is used to calculate area-averaged air temperature and wind speed. The accuracy of the experimental method and the tomographic inversion algorithm is exemplarily demonstrated for one day without remarkable differences in the horizontal temperature field, determined by independent in situ measurements at different points within the measuring field. The differences between the conventionally determined air temperature (point measurement and the air temperature determined by tomography (area-averaged measurement representative for the area of the measuring field 200m x 260m were below 0.5 K for an average of 10 minutes. The differences obtained between the wind speed measured at a meteorological mast and calculated from acoustic measurements are not higher than 0.5 ms-1 for the same averaging time. The tomographically determined area-averaged distribution of air temperature (resolution 50 m x 50 m can be used to estimate the horizontal gradient of air temperature as a pre-condition to detect horizontal turbulent fluxes of sensible heat.

  18. Skip the trip: air travelers' behavioral responses to pandemic influenza.

    Directory of Open Access Journals (Sweden)

    Eli P Fenichel

    Full Text Available Theory suggests that human behavior has implications for disease spread. We examine the hypothesis that individuals engage in voluntary defensive behavior during an epidemic. We estimate the number of passengers missing previously purchased flights as a function of concern for swine flu or A/H1N1 influenza using 1.7 million detailed flight records, Google Trends, and the World Health Organization's FluNet data. We estimate that concern over "swine flu," as measured by Google Trends, accounted for 0.34% of missed flights during the epidemic. The Google Trends data correlates strongly with media attention, but poorly (at times negatively with reported cases in FluNet. Passengers show no response to reported cases. Passengers skipping their purchased trips forwent at least $50 M in travel related benefits. Responding to actual cases would have cut this estimate in half. Thus, people appear to respond to an epidemic by voluntarily engaging in self-protection behavior, but this behavior may not be responsive to objective measures of risk. Clearer risk communication could substantially reduce epidemic costs. People undertaking costly risk reduction behavior, for example, forgoing nonrefundable flights, suggests they may also make less costly behavior adjustments to avoid infection. Accounting for defensive behaviors may be important for forecasting epidemics, but linking behavior with epidemics likely requires consideration of risk communication.

    Full Text Available Lifestyle diseases particularly coronary artery disease (CAD has been noted to be the most important   cause of the morbidity and mortality all over the world.  India is currently passing through this epidemic so much  so that it would be taking a heavy toll of Indian youth and economy to the tune of some 1.6 trillion $ during 2015-2030 . The main causative factors for CAD identified as coronary risk factors are: smoking / tobacco, physical inactivity, faulty diet, hypertension, diabetes, high level of cholesterol and stress. As most of these risk factors are lifestyle related attempt to modify them by appropriate interventions form the cornerstone of prevention of CAD epidemic.  Studies done by Dean Ornish and several others prompted us to plan an interventional case control study in 640 patients of established CAD. These cases were given power point presentation regarding healthy lifestyle on one to one basis and followed up at three and six months. Primary outcomes variable were change in smoking /tobacco habits, physical activity, obesity, dietary habits, control of hypertension, diabetes and lipid profile.  At the end of intervention it was possible to bring down the tobacco consumption, improve physical activity, better control of hypertension ( p< 0.03 , reduction in obesity ( p= 0. 0005 and raising HDL cholesterol ( p 0.05 significantly in test group.  Taking cue from above study a five step innovative strategy was developed for effective implementation of healthy life style in coronary patients attending Cardiac Clinic at HAH Centenary Hospital, Jamia Hamdard. This strategy  included sensitizing patients to  locally developed visuals , posters and pamphlets at  registration desk , concurrent counseling by attending doctor  at the end of clinical examination ,  and showing patients  and their  family the features of atherosclerosis during  carotid  ultrasound assessment . These points were again reinforced at follow up

    Full Text Available Introduction. Oxygen is an essential element for sustaining the life of aerobes; however, in certain conditions it may be toxic for these organisms. This is due to so-called reactive oxygen species – ROS. Factors which cause the production of free radicals include ionizing radiation, UV radiation, high temperature, and hazardous substances, such as phenols, carbon monoxide, e.g. in smokers, also air pollution and drugs. Objective. The objective of the study was analysis of the total antioxidant status (TAS in stimulated and unstimulated saliva, according to the number of active carious lesions in generally healthy non-smokers aged 15–17. Materials and method. The study covered 113 adolescents aged 15–17 in whom the state of dentition was evaluated using the DMFT (Decayed-Missing-Filled index, and oral hygiene assessed based on the OHI-S (Oral Hygiene Index-Simplified index. TAS in saliva was determined by means of a Randox Labolatories Ltd. test kit, by the spectrophotometric method. Results. Based on the results of the study, it was found that in the population examined an increase in the number of carious lesions was accompanied by a significant decrease in the TAS, both in stimulated and unstimulated saliva. Conclusions. A health-promoting life style, maintenance of basic principles of oral hygiene and care of general health through the elimination of harmful habits decrease the risk of dental caries.

    Previous intercity travel demand models in terms of their ability to predict air travel in a useful way and the need for disaggregation in the approach to demand modelling are evaluated. The viability of incorporating non-conventional factors (i.e. non-econometric, such as time and cost) in travel demand forecasting models are determined. The investigation of existing models is carried out in order to provide insight into their strong points and shortcomings. The model is characterized as a market segmentation model. This is a consequence of the strengths of disaggregation and its natural evolution to a usable aggregate formulation. The need for this approach both pedagogically and mathematically is discussed. In addition this volume contains two appendices which should prove useful to the non-specialist in the area.

    This paper aims to estimate the effects of changing life style and consumption demands driven by income growth and urbanization on increase of energy requirements in China, and es- timate the impacts of improvement in household consumption on mitigating energy requirements towards 2020, based on input-out- put analysis and scenarios simulation approach. The result shows that energy requirement per capita has increased by 159% for urban residents and 147% for rural residents from 1995 to 2004. Growth in household consumption driven by income growth and urbanization may induce a successive increase in energy require- ments in future. Per capita energy requirements of urban residents will increase by 240% during 2002-2015 and 330% during 2002-2020. Urbanization might lead to 0.75 billion ton of increment of energy requirements in 2020. About 45%-48% of total energy requirements in China might be a consequence of residents' life styles and the economic activities to support consumption demands in 2020. Under low-carbon life style scenario, per capita energy requirements of urban residents may decline to 97% in 2015 and 92% in 2020 in contrast with baseline scenario. That implies that China needs to pay a great attention to developing green low- carbon life style in order to realize mitigation target towards 2020.

    Aircrew and passengers are exposed to cosmic radiation, in particular when travelling routes close to the poles and in high altitudes. The paper reviews current radiation measurement and estimation approaches as well as the actual level of cosmic radiation that personnel and travellers receive and summarizes the available epidemiological evidence on health effects of cosmic radiation. On average, German aircrew is exposed to les than 5 mSv per annum, and even frequent travellers only rarely reach values above 1 mSv/year. Cohort studies among aircrew have found very little evidence for an increased incidence or mortality of radiation-associated cancers. Only malignant melanoma rates have consistently found to be increased among male aircrew. Socioeconomic and reproductive aspects are likely to contribute to the slightly elevated breast cancer risk of female aircrew. Cytogenetic studies have not yielded consistent results. Based on these data overall risk increases for cancer among occupationally exposed aircrew appear unlikely. This also applies to air travellers who are usually exposed to much lower radiation levels. Occasional air travel during pregnancy does not pose a significant radiation risk, but further considerations apply in this situation. The currently available studies are limited with regard to methodological issues and case numbers so that a continuation of cohort studies in several European countries is being planned. (orig.)

    We analyzed cancer mortality trends in 3282 elderly subjects from two general Italian populations with different life-style patterns taking part in the Cardiovascular Study in the Elderly (CASTEL). The aim of the study was to evaluate which predictors were able to influence cancer mortality. Age, gender, tobacco smoking, the presence of respiratory symptoms, increased serum levels of ALT and ALP, and the town of residence were powerful predictors. Subjects living in Chioggia (low income, rural) had significantly greater lung and liver cancer mortality, compared with those living in Castelfranco (industrial). The findings suggest that an incongruous life-style (smoking, alcohol consumption, poor hygienic conditions) may increase cancer mortality despite the favorable environmental conditions typical of rural Mediterranean areas.

    Mind and body are inseparable entities and influences each other until death. Many factors such as stress, anxiety, depression, negative thoughts, unhealthy life style, unwholesome diet etc., disturb mental and physical wellbeing. Senile dementia is the mental deterioration, i.e, loss of intellectual ability associated with old age. It causes progressive deterioration of mental faculties, e.g., memory, intellect, attention, thinking, comprehension and personality, with preservation of normal level of consciousness. Two major types of senile dementia have been identified, namely that due to generalized atrophy in the cortical area of the brain (Alzheimer's type) and that due to vascular disorders mainly due to stroke. According to DSM-IV (diagnostic and statistical manual of mental disorders), the essential feature of dementia is the development of multiple cognitive deficits that include memory impairment and at least one of the following cognitive disturbances such as aphasia, apraxia, agnosia, or a disturbance in executive function. For the present study, a standardized questionnaire in the form of proforma incorporating types of foods (madhura, amla and lavana rasayukta ahara etc.) and life style (divaswapna, ratrijagarana and manasika bhavas etc) is prepared. To assess manasika bhava, Hamilton Anxiety Rating Scale, Hamilton Depression Rating Scale, Brief Psychiatry Rating Scale, and standardized gradations of anumana pariksha of manasika bhavas mentioned by Charaka at Vimana Sthana 4/8 were adopted. In this study, most of the patients had disturbed sleep, tendency to indulge in defective dietary habits and kapha vitiating diets and life style. On Hamilton Anxiety Rating Scale, patients had anxiety, tension, depression, difficulty in concentration, and memory. On Hamilton Depression Rating Scale, these patients had anxiety, depression, and hypochondriasis. On Brief Psychiatry Rating Scale, psychological factors affected include: anxiety, depression, somatic

  19. Fungal life-styles and ecosystem dynamics: biological aspects of plant pathogens, plant endophytes and saprophytes

    Science.gov (United States)

    Rodriguez, R.J.; Redman, R.S.

    1997-01-01

    This chapter discusses various biochemical, genetic, ecological, and evolutionary aspects of fungi that express either symbiotic or saprophytic life-styles. An enormous pool of potential pathogens exists in both agricultural and natural ecosystems, and virtually all plant species are susceptible to one or more fungal pathogens. Fungal pathogens have the potential to impact on the genetic structure of populations of individual plant species, the composition of plant communities and the process of plant succession. Endophytic fungi exist for at least part of their life cycles within the tissues of a plant host. This group of fungi is distinguished from plant pathogens because they do not elicit significant disease symptoms. However, endophytes do maintain the genetic and biochemical mechanisms required for infection and colonization of plant hosts. Fungi that obtain chemical nutrients from dead organic matter are known as saprophytes and are critical to the dynamics and resilience of ecosystems. There are two modes of saprophytic growth: one in which biomolecules that are amenable to transport across cell walls and membranes are directly absorbed, and another in which fungi must actively convert complex biopolymers into subunit forms amenable to transportation into cells. Regardless of life-style, fungi employ similar biochemical mechanisms for the acquisition and conversion of nutrients into complex biomolecules that are necessary for vegetative growth, production and dissemination of progeny, organismal competition, and survival during periods of nutrient deprivation or environmental inclemency.

    This study examines the relationships between the online life-styles of South Korean students as Internet users and Internet use, their tendency toward Internet addiction, and the level of cyber ethics. A sample of 324 students, aged between 18 and 23 years, from a medium-sized university in South Korea was asked to complete a survey. They were categorized into three groups depending on their online life-styles: a Social group (SG), an Individual group (IG), and a Loner group (LG). In the following analyses, no group difference was found in hours of Internet use on either weekdays or weekends, but the SG reported higher engagement in interaction-oriented activities (e.g. blogging, games, and instant messenger services) than the LG. As for tendency toward Internet addiction, all three groups belonged to the first phase of the "at-risk" classification in Korea. Interestingly, the IG characteristics of sensation seeking and independence reported the lowest scores in cyber ethics, while the LG characteristics of apathetic attitude toward the Internet reported the highest scores in cyber ethics. This preliminary study showed that Internet users impose different meanings and values on their Internet experiences, which contribute to their use of Internet services, their tendency toward Internet addiction, and their level of cyber ethics.

    This study investigated personal and life-style-related variables and stress levels in dual-earner families in the preschool stage of family development. The sample was composed of 92 families receiving child day care through a major day care provider in the Upper Midwest. The Family Inventory of Life Events and Changes was used to measure the family stress level. The majority of dual-earner families in this sample were experiencing a moderate level of family stress based on national stress level norms calculated for families in the preschool stage of development. Parental age and age of children were statistically related to the family stress level. Life-style-related variables statistically significant in this study were amount of income and satisfaction with income level, satisfaction with child care, and flexibility in vacation scheduling. Parents who could easily schedule vacations during the same time period had significantly lower family stress levels than parents who had difficulty scheduling vacations together, p less than .003. Additionally, parents who reported being forced to take separate vacations because of their work schedules had statistically higher scores on family stress than parents who had never had to take separate vacations because of work schedules, p less than .002.

    Full Text Available This study is aimed to segment the Notebook PC market using VALS life style and to find out the differences between these segments. Vals specifically defines the consumer segments based on personality traits influencing the market behaviors.According to Vals, consumers are divided to eight categories not only based on psychological variables, but also income, education level, buying demands, and some other factors.Life style and values are determinant factors of consumer's decision-making. This study seeks to identify different segments of Notebook PC market and specify the requirements of each segment.To do this, we designed a written questionnaire, distributed 400 questionnaires between the students of Ferdowsi University of Mashhad, and collected 308 ones. The final response rate after eliminating five non-eligible questionnaires was 77%. For data analyzingand answering the research questions, descriptive and inferential statistics were used. The results indicated that each market segment requires different features and requirements as for its psychological attributes. At the end, research limitations were enumeratedand some suggestions for future studies were made.

    Full Text Available Growth in sucrose medium was previously found to trigger the expression of functions involved in the plant associated life style of the endophytic bacterium Enterobacter sp. 638. Therefore, comparative transcriptome analysis between cultures grown in sucrose or lactate medium was used to gain insights in the expression levels of bacterial functions involved in the endophytic life style of strain 638. Growth on sucrose as a carbon source resulted in major changes in cell physiology, including a shift from a planktonic life style to the formation of bacterial aggregates. This shift was accompanied by a decrease in transcription of genes involved in motility (e.g., flagella biosynthesis and an increase in the transcription of genes involved in colonization, adhesion and biofilm formation. The transcription levels of functions previously suggested as being involved in endophytic behavior and functions responsible for plant growth promoting properties, including the synthesis of indole-acetic acid, acetoin and 2,3-butanediol, also increased significantly for cultures grown in sucrose medium. Interestingly, despite an abundance of essential nutrients transcription levels of functions related to uptake and processing of nitrogen and iron became increased for cultures grown on sucrose as sole carbon source. Transcriptome data were also used to analyze putative regulatory relationships. In addition to the small RNA csrABCD regulon, which seems to play a role in the physiological adaptation and possibly the shift between free-living and plant-associated endophytic life style of Enterobacter sp. 638, our results also pointed to the involvement of rcsAB in controlling responses by Enterobacter sp. 638 to a plant-associated life style. Targeted mutagenesis was used to confirm this role and showed that compared to wild-type Enterobacter sp. 638 a ΔrcsB mutant was affected in its plant growth promoting ability.

    Results of sociological survey of medical personnel of typical agroindustrial area of Novgorod Oblast are presented. Data of self-registration of acute and chronic diseases and self-appraisal of one's health testify higher morbidity and health deterioration during last 3 years. Analysis of demographic characteristics, life-styles and labor conditions revealed complex of major factors impacting individual health and flow-out of professional medical personnel. Both amount of average monthly wage of physicians and paramedics, levels of their family income and welfare and as well degree of their inconsistence with cost of living of able-bodied population are established. Conditions of living and social maintenance, labor and off-labor activity, attitude to one's own health and spread of risk factors were analyzed. Management weaknesses of district and rural patient care institutions were established, including considerable exceeding of hygienic regulations established for medical personnel working load and higher spread of physical, chemical and biological risk factors of working environment harmful for health. Need in further enhancement of management of working process, occupational safety, labor remuneration and in increasing social safety, hygienic and curative activity of medical personnel is justified.

    Studies concerning the psychosocial aspects of skeletal dysplasias that cause disproportionate short stature have been few and have usually involved small numbers of patients. As part of a study involving patients with chondrodysplasias and their families, an assessment battery of standardised instruments designed to measure depression, anxiety, self-esteem, personal support networks, marital adjustment, and family structure were completed by patients and, in many cases, their sibs, spouses, and/or parents. This first in a series of six papers reports the results of a Life-Styles Questionnaire which provides some insights into the levels of satisfaction with various aspects of life, including friendships, employment, the use of some substances and services, and the impact of the skeletal dysplasia on career, marriage, and childbearing. Results are presented for patients and the unaffected parents of patients. Overall, the study has shown a high level of satisfaction with many aspects of life. However, there are important differences in attitudes between the married and unmarried patients, and in some cases the unaffected parents, in a number of areas including health, overall satisfaction with life, and concerns surrounding child bearing and employment.

    Objectives The purpose of this article is to explore the associations of psychosocial factors at work, life style, and stressful life events on health and work ability among white-collar workers. Methods A cross-sectional survey was conducted among workers in commercial services (n = 1141). The main outcome variables were work ability, measured by the work ability index (WAI), and mental and physical health, measured by the Short-Form Health Survey (SF-12). Individual characteristics, psychosocial factors at work, stressful life events, and lifestyle factors were determined by a questionnaire. Maximum oxygen uptake, weight, height, and biceps strength were measured during a physical examination. Results Work ability of white-collar workers in commercial services industry was strongly associated with psychosocial factors at work such as teamwork, stress handling, and self-development and, to a lesser extent, with stressful life events, lack of physical activity, and obesity. Determinants of mental health were very similar to those of work ability, whereas physical health was influenced primarily by life style factors. With respect to work ability, the influence of unhealthy life style seems more important for older workers, than for their younger colleagues. Conclusion Among white-collar workers mental and physical health were of equal importance to work ability, but only mental health and work ability shared the same determinants. The strong associations between psychosocial factors at work and mental health and work ability suggest that in this study population health promotion should address working conditions rather than individual life style factors.

    Full Text Available : Objectives: To determine the prevalence of menopause, chronic illnesses and lifestyle of middle aged women in Karachi, Pakistan. Design: A Cross Sectional survey was conducted among women of 40-60 years living in socio-economically different areas of Karachi. Information was gathered on their current menstrual status, age at menopause, body mass index, exercise habits, weekly recall of food consumed and chronic illnesses. These variables were also examined according to the socio economic status of the area where women reside. Results: A total of 1764 women in age group 40-60 years were interviewed. The prevalence of menopausal women in this age group was 39.3 percent (%. The mean age at menopause was 45.2 (±3.8 years. Only seven percent of women were doing some kind of exercise and approximately eighty percent had their Body Mass Index ≥ 23 kg/m2 according to Asian Standard. Approximately 31 percent (% of women reported eating any type of meat at least four times a week, of these most were from higher income area. Majority consumed meat less than three times a week. Similar pattern was observed for consumption of fruits and milk. Approximately 36 percent (% of women reported diabetes mellitus, hypertension, cardio vascular heart disease and arthritis. Conclusion: The sedentary life style, obesity and chronic illnesses are highly prevalent and are serious emerging public health problem for 40-60 years old women of Karachi. We recommend that awareness about balanced diet, exercise and healthy eating habits should be inculcated in women early in life, where possible through schools and media. Health policies and public health messages should be formulated according to the various stages of life cycle of women, so that women can prepare themselves for the next stage of life.

    2013-04-01

    Full Text Available Previous work in the mud volcanoes from the Gulf of Cadiz (South Iberian Margin revealed a high number of chemosymbiotic species, namely bivalves and siboglinid polychaetes. In this study we give an overview of the distribution and life styles of these species in the Gulf of Cadiz, determine the role of autotrophic symbionts in the nutrition of selected species using stable isotope analyses (δ13C, δ15N and δ34S and investigate the intra-specific variation of isotope signatures within and between study sites. During our studies, we identified twenty siboglinidae and nine bivalve chemosymbiotic species living in fifteen mud volcanoes. Solemyid bivalves and tubeworms of the genus Siboglinum are widespread in the study area, whereas other species were found in a single mud volcano (e.g. "Bathymodiolus" mauritanicus or restricted to deeper mud volcanoes (e.g. Polybrachia sp., Lamelisabella denticulata. Species distribution suggests that different species may adjust their position within the sediment according to their particular needs, and to the intensity and variability of the chemical substrata supply. Tissue stable isotope signatures for selected species are in accordance with values found in other studies, with thiotrophy as the dominant nutritional pathway, and with methanotrophy and mixotrophy emerging as secondary strategies. The heterogeneity in terms of nutrient sources (expressed in the high variance of nitrogen and sulphur values and the ability to exploit different resources by the different species may explain the high diversity of chemosymbiotic species found in the Gulf of Cadiz. This study increases the knowledge on distributional patterns and resource partitioning of chemosymbiotic species and highlights how trophic fuelling varies on spatial scales with direct implications to seep assemblages and potentially to the biodiversity of continental margin.

    Different studies have demonstrated that there are significant changes in the health and habits/life-style of university students, and it seems that Medical students also reveal a significant vulnerability to the adoption of health risk behaviours. The present study aims to (1) characterize the main sources of academic stress of the Medical School students of the University of Porto as well as the intensity with which they are experienced, (2) investigate the variations in academic stress and psychosocial variables, due to gender, year of course and displacement from home and (3) contribute, for the first time, to the understanding of stress and life-style of medical students in Portugal. The empirical study included a sample of 251 students from all 6 years of the course (160 females and 91 males), evaluated by the following instruments: (1) The Inventory of Sources of Academic Stress in Medical Education (ISASME), and the Portuguese versions of (2) the Brief Personal Survey (BPS), (3) the General Health Questionnaire 12 (GHQ-12), and (4) the Interpersonal Behaviour Survey-Brief (ICIBrief). In terms of overall levels of stress (GHQ-12), a prevalence of 58.2% of clinically significant stress symptoms was found, with the students from the basic cycle and those who are living away from home, presenting higher levels of stress. In terms of life-style, 47% of the students revealed health risk behaviours, with eating habits, physical exercise, alcohol and drug consumption, and body image being the main problem areas. Gender and year of course seem to have a significant influence on the variables studied, being the female students those who present higher levels of academic stress, stress responses (pressure/overload, physical distress, anxiety, anger/frustration, inefficiency, depression and loss of control), and low levels of coping confidence; the students of the basic cycle reveal higher levels of stress in managing their life-style (academic stress), general stress

    Full Text Available This paper aims to encompassingly show what impact low-cost airline companies have on the tourism business in Zadar County. The high cost of travel for tourists who choose to travel by airplane in the past two decades has been significantely lowered by low-cost airline companies such as Ryanair, Germanwings, Easyjet and others. Low-cost flights have ensured an increase in the number of flights, thus increasing the number of tourist visits to destinations connected to those flights. Zadar County has recognized the ability of low-cost flights to have potential for the development of tourism. Low-cost airline companies have reduced the negative balance of tourism economy. This study wishes to gather information on how much low-cost airline companies affect the increase of tourist ventures to Zadar County. Considering that the increase in number of tourist arrivals is directly linked to business revenue, it will also show how much they affect the economy in Zadar County tourism.

Elderberries have been used traditionally, and in some observational and clinical studies, as supportive agents against the common cold and influenza. This randomized, double-blind placebo-controlled clinical trial of 312 economy class passengers travelling from Australia to an overseas destination aimed to investigate if a standardised membrane filtered elderberry (Sambucus nigra L. extract has beneficial effects on physical, especially respiratory, and mental health. Cold episodes, cold duration and symptoms were noted in a daily diary and assessed using the Jackson score. Participants also completed three surveys containing questions regarding upper respiratory symptoms (WURSS-21 and quality of life (SF-12 at baseline, just before travel and at 4-days after travel. Most cold episodes occurred in the placebo group (17 vs. 12, however the difference was not significant (p = 0.4. Placebo group participants had a significantly longer duration of cold episode days (117 vs. 57, p = 0.02 and the average symptom score over these days was also significantly higher (583 vs. 247, p = 0.05. These data suggest a significant reduction of cold duration and severity in air travelers. More research is warranted to confirm this effect and to evaluate elderberry’s physical and mental health benefits.

    Intercontinental air travel can be stressful, especially for respiratory health. Elderberries have been used traditionally, and in some observational and clinical studies, as supportive agents against the common cold and influenza. This randomized, double-blind placebo-controlled clinical trial of 312 economy class passengers travelling from Australia to an overseas destination aimed to investigate if a standardised membrane filtered elderberry (Sambucus nigra L.) extract has beneficial effects on physical, especially respiratory, and mental health. Cold episodes, cold duration and symptoms were noted in a daily diary and assessed using the Jackson score. Participants also completed three surveys containing questions regarding upper respiratory symptoms (WURSS-21) and quality of life (SF-12) at baseline, just before travel and at 4-days after travel. Most cold episodes occurred in the placebo group (17 vs. 12), however the difference was not significant (p = 0.4). Placebo group participants had a significantly longer duration of cold episode days (117 vs. 57, p = 0.02) and the average symptom score over these days was also significantly higher (583 vs. 247, p = 0.05). These data suggest a significant reduction of cold duration and severity in air travelers. More research is warranted to confirm this effect and to evaluate elderberry's physical and mental health benefits.

    This paper presents a search algorithm based framework to calibrate origin-destination (O-D) market specific airline ticket demands and prices for the Air Transportation System (ATS). This framework is used for calibrating an agent based model of the air ticket buy-sell process - Airline Evolutionary Simulation (Airline EVOS) -that has fidelity of detail that accounts for airline and consumer behaviors and the interdependencies they share between themselves and the NAS. More specificially, this algorithm simultaneous calibrates demand and airfares for each O-D market, to within specified threshold of a pre-specified target value. The proposed algorithm is illustrated with market data targets provided by the Transportation System Analysis Model (TSAM) and Airline Origin and Destination Survey (DB1B). Although we specify these models and datasources for this calibration exercise, the methods described in this paper are applicable to calibrating any low-level model of the ATS to some other demand forecast model-based data. We argue that using a calibration algorithm such as the one we present here to synchronize ATS models with specialized forecast demand models, is a powerful tool for establishing credible baseline conditions in experiments analyzing the effects of proposed policy changes to the ATS.

    Full Text Available Abstract Background Studies from Sweden have reported association between immigrant status and incidence of cardiovascular diseases. The nature of this relationship is unclear. We investigated the relationship between immigrant status and risk of heart failure (HF hospitalization in a population-based cohort, and to what extent this is mediated by hypertension and life-style risk factors. We also explored whether immigrant status was related to case-fatality after HF. Methods 26,559 subjects without history of myocardial infarction (MI, stroke or HF from the community-based Malmö Diet and Cancer (MDC cohort underwent a baseline examination during 1991-1996. Incidence of HF hospitalizations was monitored during a mean follow-up of 15 years. Results 3,129 (11.8% subjects were born outside Sweden. During follow-up, 764 subjects were hospitalized with HF as primary diagnosis, of whom 166 had an MI before or concurrent with the HF. After adjustment for potential confounding factors, the hazard ratios (HR for foreign-born were 1.37 (95% CI: 1.08-1.73, p = 0.009 compared to native Swedes, for HF without previous MI. The results were similar in a secondary analysis without censoring at incident MI. There was a significant interaction (p Conclusions Immigrant status was associated with long-term risk of HF hospitalization, independently of hypertension and several life-style risk factors. A significant interaction between WC and immigrant status on incident HF was observed.

  20. How can air travel contribute to the costs of adapting to climate change?

    [English] By 2050, the costs of adapting to climate change in developing countries could reach US$100 billion per year, according to estimates from UNDP and the World Bank. Despite international pledges of financial support to developing countries for adaptation (and mitigation), it is unclear where this funding will come from. New and additional sources of funding for adaptation are desperately needed. The International Air Passenger Adaptation Levy (IAPAL) is a proposed new purchase tax on air tickets, the proceeds of which would be dedicated to investment in adaptation to climate change. IAPAL would not mitigate the effects of climate change because it does not aim to reduce flight numbers and therefore aviation's contribution to climate change. IAPAL could immediately raise up to US$10 billion annually for adaptation, and considerably more in the longer term. Aviation is a sector with a relatively low price-elasticity of demand, meaning that price increases do not greatly reduce the demand for most flights. This makes taxation an unsuitable method of reducing demand but indicates that it could be suitable for raising revenue. It also suggests that it could raise a considerable amount of revenue. This paper revisits the key assumptions made in the original paper proposing this scheme (by Mueller and Hepburn in 2006), while also offering fresh thinking. This paper analyses current international agreements, to determine the feasibility of introducing IAPAL. The International Civil Aviation Organization (ICAO) is the UN agency with global responsibility for establishing standards, recommended practices and guidance on various aspects of international aviation, including environmental protection. Despite ICAO's current focus on the mitigation aspects of aviation, the evidence suggests no likely contradiction in including a levy for adaptation purposes. This is providing that the purpose of IAPAL – adaptation rather than mitigation – is clear and that

    International travel is undertaken by large, and ever increasing numbers of people for professional, social, recreational and humanitarian purposes, and this upward trend looks set to continue. Travelers are exposed to a variety of health risks of the unfamiliar environment of the visited area. The risk of exposure is determined by destination, duration of the visit, purpose of the visit, behavior of the traveler and underlying physical and biological status of the traveler. However, most risks can be minimized by suitable precautions taken before, during and after travel. Travelers can themselves, also, easily introduce any infectious agents they may harbor to the visited area. Many infectious diseases have been introduced in many parts of the world through travel and trade. Travel has been identified as a prime factor in the global spread of infectious diseases. In a world of rapid air travel, no country is safe from infectious diseases. An outbreak in one country can easily and rapidly be transmitted across long distances to affect other countries through travel and trade. The World Health Organization devotes great attention to prevention and control of global spread of infectious diseases and minimizing the negative effect of international travel on health. The main strategies of the World Health Organization for minimizing the negative effects of expanding travel on global health security include developing the necessary strategies, rules and regulations; strengthening global communicable diseases surveillance and response; dissemination of related information throughout the world and strengthening national capacity for communicable diseases surveillance and response.

    Arterial hypertension (HA) is a public health problem, 15 to 30% of adults in our country suffer it. There are different facts that influence its outcome. Among young people the main factors are: alcoholism, smoking tobacco, overweight, diabetes, family history, sedentarism and psychological aspects. The main object of this study, was to detect the risk factor for the development of HA in the students of the University. For this search 489 sophomore students class at the Medical School of the University of Mexico (UNAM), between 17 and 24 years old, were studied. Our results showed that positive family history was more prevalent among females. Among males life-style factors were more significant, the main factor was sedentarism, whereas lesser factor was overweight. The prevalence of HA was higher for diastolic hypertension than for systolic. We concluded there are many risk factors that influence the development of HA, which are distributed in a different way according to gender preventive measures are recommended.

    Full Text Available Childhood obesity and overweight are a general public health concern in a transition society. Thus, the objective of the study was to determine the prevalence of overweight, obesity and their correlates with socio-demographic and life style related factors.This cross-sectional study was conducted on 760 representative samples of preschool children aged 2 to 5 years in urban area of Babol, northern Iran. The weight and height were measured with standard method and the socio-demographic and life style data were collected by interviewing their parents. The diagnosis of overweight and obesity was based on CDC criteria.The prevalence rate of overweight and obesity were 11.8%, 15% respectively. There was no significant difference observed between sexes. The odds of overweight/obesity was elevated more than double in age 4-5 years compared with 2-3 years(OR=2.53, 95%CI:1.71-3.73. By parental education at university level, the odds ratio significant decreased compared with primary level (OR=0.34, 95%CI: 0.31-0.90 and OR=0.49, 95%CI: 0.34-0.98 for mothers and fathers respectively. Parental obesity is positively associated with overweight/obesity risk OR=2.67(95%CI: 1.75, 4.07 and 1.61(95% CI: 1.04-2.150 for mothers and fathers respectively. While spending ≥2 hours per day for Tv watching and ≥1 hours for playing with computer games tended to elevate the risk but not significant.The findings indicate that overweight and obesity are high in preschool children in Babol. Increasing child age, parental obesity, spending more times on TV and playing with computer games are positively associated with overweight/obesity while parental education at university level is inversely associated.

    If you have a fear of flying, then probably the last thing on your mind when you are 10 km above the ground is what might be going on in the depths of the galaxy. But airline pilots and cabin crew might want to brush up on their astroparticle physics. High-energy particles coming from violent galactic events mean that radiation exposure for aircrew is higher than it is for most people classified as radiation workers. But the type of radiation that they are exposed to is very different. The majority of the exposure comes from cosmic radiation that originates outside our solar system. Violent events such as stellar flares, supernovae and the explosion of galactic nuclei produce a concoction of subatomic particles, primarily protons and electrons. The energies of these particles can be greater than 10{sup 20} eV - billions of times higher than in the most powerful particle accelerators - although such energetic particles are very rare. Nuclear particles, which comprise about 98% of the radiation, typically have energies that are between 100 MeV and 10 GeV per nucleon. Proportional counter that can measure cosmic radiation is described. (U.K.)

    The association between long haul travel and the risk of venous thromboembolism are suspected for long time. Mostly air travel related thrombosis series have been reported in the literature. Risk factors can be classified as: 1. travel related factors (coach position, immobilization, prolonged air travel, narrow seat and room, diuretic effect of alcohol, insufficient fluid intake, dehydration, direct pressure on leg veins, rare inspiration). 2. air plane related risk factors (low humidity, relative hypoxia, stress). 3. patient related factors (hereditary and acquired thrombophylia, previous deep venous thrombosis, age over 40, recent surgery or trauma, gravidity, puerperium, oestrogen containing pills, varicosity, chronic heart disease, obesity, fever, diarrhoea, vomiting, smoking). No patient related factors were found in some cases. To reduce the hazards air travellers are rightly concerned to know the level of the risk and the airlines should be responsible for this information. People should discuss with their physician what prophlylactic measures should be taken, such as compression stockings or low molecular weight heparin. Not only flight but car, bus and train travellers are also at risk of developing venous thromboembolism. Long haul travel alone is a separate risk factor for venous thromboembolism.

    The number of Japanese oversea travelers has gradually increased year by year, however they usually pay less attention to the poor physical condition at the voyage place. Many oversea travelers caught vaccine preventable diseases in developing countries. The Vaccine Guideline for Oversea Travelers 2010 published by Japanese Society of Travel Health will be helpful for spreading the knowledge of travelers' vaccine and vaccine preventable diseases in developing countries. Many travelers' vaccines have not licensed in Japan. I hope these travelers' vaccines, such as typhoid vaccine, meningococcal vaccine, cholera vaccine and so on will be licensed in the near future.

    The self-reported health-promoting life-style (HPL) of 130 well adults in a primary care clinical population was examined in relation to the cognitive/perceptual and sociodemographic factors hypothesized in Pender's Health Promotion Model (1987) to predict this behavior. Subjects were randomly drawn from the clients of a group nurse practitioner practice emphasizing health maintenance. Data were collected by mailed survey (response rate, 59%) with one telephone prompt. The mean age of the subjects was 39.7 years; 72.3% were female; 51.2% were married; 47.7% had college degrees; and 67.4% were white. Blacks were underrepresented in the sample compared to the practice population (chi = 7.56, p = .006). Using multiple regression, the definition of health, importance of health, health locus of control, age, gender, marital status, race, education, income, and rural/urban residence were studied to determine their effects on health-promoting behavior. Results generally supported the Pender Model. Defining health eudiamonistically, that is, as exuberant well-being (rather than adaptive, functional, or absence of disease), predicted HPL. Ranking health above other values such as achievement and harmony had no effect; chance health locus of control had a negative relationship. In the final regression model, predictors of HPL were eudiamonistic conception of health and college education (p = .0001, R2 = 17). Based on this data, considerations of a clients' health conception when framing health-promotion messages is warranted in this population.

    Full Text Available Patients with respiratory disease regularly seek the convenience of commercial airline travel. In addition to the stresses that all patients with chronic disease encounter, these patients are exposed to the affects of acute altitudinal hypoxemia. This in turn has the potential to produce significant symptoms and complications in-flight for patients with chronic respiratory disease. This article reviews the current literature, and seeks to help the practicing physician by providing recommendations on which patients should be assessed preflight, the type of assessment that should be carried out and recommendations for providing advice to these travelling patients.

    The Connected Traveler framework seeks to boost the energy efficiency of personal travel and the overall transportation system by maximizing the accuracy of predicted traveler behavior in response to real-time feedback and incentives. It is anticipated that this approach will establish a feedback loop that 'learns' traveler preferences and customizes incentives to meet or exceed energy efficiency targets by empowering individual travelers with information needed to make energy-efficient choices and reducing the complexity required to validate transportation system energy savings. This handout provides an overview of NREL's Connected Traveler project, including graphics, milestones, and contact information.

    Full Text Available The study, part of the project "Atherosclerotic cardiovascular diseases, lipemic disorders, hypertension, obesity and diabetis mellitus in a population of the metropolitan area of the southeastern region of Brazil", had the following objectives: a the characterization and distribution among typical human socio-economic groupings, of the prevalence of some particular habits which constitute aspects of life-style-the use of tobacco, the use of alcohol and sedentary activity; b the establishment of the interrelation between the above-mentioned habits and some lipemic disorders. The prevalence of the habits cited behaved in the following manner: the use of tobacco predominated among men, distributed uniformly throughout the social strata; among the women the average percentage of smokers was 18,9%, a significant difference occurring among the highest socio-economic class, where the average was of 40.2%. The sedentary style of life presented high prevalence, among both men and women with exception of the women of the highest socio-economic level and of the skilled working class. The use of alcohol, as one would expect, is a habit basically practised by the men, without any statistically significant differences between classes. For the purpose of establishing associations between these risk fictors and lipemic conditions four situations were chosen, of the following characteristics: 1- total cholesterol > or = 220 mg/dl and triglycerides > or = 150 mg/dl; 2- HDL cholesterol or = 150 mg/dl; 3- HDL cholesterol or = 150 mg/dl, and the following independent variables: age, use of tobacco and the interactions between obesity and smoking, age and sedentary lifestyle, sex and obesity (R2=22%; the standardized B coefficient showed that the variables with the greatest weight in the forecasting of the variation in the levels of cholesterol were smoking and the interaction between obesity and smoking.

    Background: Adolescents are at substantial risk of acquiring behaviors which might influence their health status. This study was aimed to assess the proportion of school going adolescents (both males and females) with poor self-perceived health and its associated factors. Methodology: A cross-sectional study was conducted in three major cities of Pakistan i.e. Karachi, Lahore and Quetta. From each city, six (6) secondary schools were randomly selected (3 public and 3 private). Pre-tested, self-administered questionnaire was distributed to students. Binary logistic regression analysis was conducted to determine independent factors associated with poor self-perceived health. Results: Approximately 29% adolescents (119/414) reported poor self-perceived health. Individual and parental factors significantly associated with poor self-perceived health were being male (AOR = 1.75, 95% CI: 1.09 – 2.79), living in extended family (AOR = 2.65, 95% CI: 1.66 – 4.22), unskilled employment of father (AOR = 2.17, 95% CI: 1.35 – 3.48), lack of parental-child communication (AOR = 1.74, 95% CI: 1.03 – 2.91) and unfair treatment by parents (AOR = 1.80, 95% CI: 1.09 – 2.96). Life style factors such as use of smokeless tobacco (AOR = 2.14, 95% CI: 1.26 – 3.96) and unhealthy diet (AOR = 3.60, 95% CI: 1.76 – 7.33) were associated with poor self-perceived health. Conclusion: Better employment opportunities for father, parental counseling and increase awareness for adolescents about healthy diet are recommended to improve adolescent self-perceived health in Pakistan.

    Full Text Available Background: Multiple Sclerosis (MS is an autoimmune disease with unknown factor. The prevalence and incidence rate of this disease had an upward trend in many regions in the world such as Middle east and consequently in Iran over the recent years. As the risk factors of this increased trend and high-prevalence is unknown in Iran, the current study has been designed to evaluate the correlation between MS dispersal with urbanization, life style and industry, as an ecological research.Methods: This retrospective study was designed as an ecological approach in 2011. Data were collected from three databases by high precision (CI95% from national registry plans. The subjects of study were provinces of Iran (n=31. The linear regression was used to perform statistical analyses.Results: The obtained results indicated an ascendant trend of MS during the recent years, as the incidence of this dis-ease reached from 26.24/100000 (CI95% people in 2006 to 44.53/100000 (CI95% in 2011. There is a direct correla-tion (P<0.05 between the percentage of urbanization and the percentage of male smokers with the prevalence of MS in provinces.Conclusion: The role of smoking was more highlighted in this study as a probable factor in increasing risk and caus-ing MS disease. Urbanization could be introduced as an augmentative factor, but this is a combination of several com-plex factors that this effect must be appraised with smaller scale in other researches.

    U.S. airports and airliners are prime terrorist targets. Not only do the facilities and equipment represent high-value assets, but the fear and dread that is spread by such attacks can have tremendous effects on the U.S. economy. This article presents the methodology, data, and estimates of the macroeconomic impacts stemming from behavioral responses to a simulated terrorist attack on a U.S. airport and on a domestic airliner. The analysis is based on risk-perception surveys of these two scenarios. The responses relate to reduced demand for airline travel, shifts to other modes, spending on nontravel items, and savings of potential travel expenditures by U.S. resident passengers considering flying domestic routes. We translate these responses to individual spending categories and feed these direct impact results into a computable general equilibrium (CGE) model of the U.S. economy to ascertain the indirect and total impacts on both the airline industry and the economy as a whole. Overall, the estimated impacts on GDP of both types of attacks exceed $10B. We find that the behavioral economic impacts are almost an order of magnitude higher than the ordinary business interruption impacts for the airliner attack and nearly two orders of magnitude higher for the airport attack. The results are robust to sensitivity tests on the travel behavior of U.S. residents in response to terrorism.

    Taxis play important roles in modern urban transportation systems, especially in mega cities. While providing necessary amenities, taxis also significantly contribute to traffic congestion, urban energy consumption, and air pollution. Understanding the travel patterns of taxis is thus important for addressing many urban sustainability challenges. Previous research has primarily focused on examining the statistical properties of passenger trips, which include only taxi trips occupied with passengers. However, unoccupied trips are also important for urban sustainability issues because they represent potential opportunities to improve the efficiency of the transportation system. Therefore, we need to understand the travel patterns of taxis as an integrated system, instead of focusing only on the occupied trips. In this study we examine GPS trajectory data of 11,880 taxis in Beijing, China for a period of three weeks. Our results show that taxi travel patterns share similar traits with travel patterns of individuals but also exhibit differences. Trip displacement distribution of taxi travels is statistically greater than the exponential distribution and smaller than the truncated power-law distribution. The distribution of short trips (less than 30 miles) can be best fitted with power-law while long trips follow exponential decay. We use radius of gyration to characterize individual taxi's travel distance and find that it does not follow a truncated power-law as observed in previous studies. Spatial and temporal regularities exist in taxi travels. However, with increasing spatial coverage, taxi trips can exhibit dual high probability density centers.

    Full Text Available Vegan and vegetarianism that becomes an increasing trend day by day is a life style and a life philosophy and a bioethical approach. The reason of choosing for being a vegan/ vegetarian differs according to people’s preferences. These may be; respecting for a living things’ life, taking an ethical position against exploitation of animals, reducing ecological damage, being healthy and religious purposes. Most people believe that the nature and animals just exist for the sake of them. Accordingly, people use and consume them with impunity. Human exploits animals to use them for different kinds of purposes he wishes. While some of them are cared and fed at home (like cats, dogs some of them are raised at farms for eating or to benefit from their products such as eggs and milk. There are also some other animals to be used for entertaining purposes in circuses or camel wrestling and bull fighting. There are also animals used for their abilities. A police dog can be given as an example. Police dogs are used for their powerful sense of smell that people have not. There have been some traditional practices that include some animals. Other two examples are turkeys being eaten at thanksgiving day and a ram decorated at the Festival of Sacrifice and sent to the fiancée‘s home. On the one hand it is observed that consuming meat of an animal has different meanings in terms of gender considerations. For example, eating meat is viewed as masculine behavior while eating vegetables is feminine. In addition, meat at advertisements is generally symbolized as a woman. These kinds of behaviors, attitudes, beliefs affect development of veganism/ vegetarianism positively or negatively. In this paper, veganism/vegetarianism is described as a life style.

    The EI Ni(n)o and Southern Oscillation (ENSO) is an interannual phenomenon involved in the tropical Pacific sea-air interactions. In this paper, an asymptotic method of solving nonlinear equations for the ENSO model is proposed. And based on a class of oscillator of the ENSO model and by employing the method of homotopic mapping, the approximate solution of equations for the corresponding ENSO model is studied. It is proved from the results that homotopic method can be used for analysing the sea surface temperature anomaly in the equatorial Pacific of the sea-air oscillator for the ENSO model.

    Full Text Available Abstract Background Preventing excessive weight gain during pregnancy is potentially important in the prevention of overweight and obesity among women of childbearing age. However, few intervention studies aiming at weight management during pregnancy have been performed and most of these interventions were not as successful as expected. In this paper the design of the New Life(style study is described as well as the content of the individually tailored intervention program, which focuses on controlling weight development during pregnancy. Methods The effectiveness of the New Life(style intervention program versus usual care by midwives is evaluated in a randomised controlled trial. Women who expect their first child and visit one of the participating midwifery practices are included. The intervention is standardised in a protocol and executed by trained counsellors with the women who are randomised in the intervention group. During 5 sessions – at 18, 22, 30 and 36 weeks of pregnancy and at 8 weeks postpartum – individual weight gain is discussed in relation to weight gain guidelines for pregnant women of the American Institute of Medicine. Counsellors coach the women to maintain or optimise a healthy lifestyle, in a period of drastic physical and mental changes. Data is collected at 15, 25, 35 weeks of pregnancy and at 6, 26, and 52 weeks after delivery. Primary outcome measures are body weight, BMI, and skinfold thickness. Secondary outcome measures include physical activity, nutrition and blood levels of factors that are associated with energy homeostasis. Discussion Results of the current RCT will improve the knowledge of determinants of weight gain during pregnancy, weight retention after childbirth and of the effectiveness of the intervention program that is described. Caregivers and researchers in the field of health promotion are offered more insight in specific elements of the New Life(style intervention program.

    During the past several decades, the number of both business and tourist travels has greatly increased. Among them are persons suffering from chronic diseases, including diabetics for whom travels pose the additional health-hazard. Irrespective of better education, self-control and constantly improving quality of specialistic equipment available, diabetics still are the group of patients requiring particular attention. In the case of travelling diabetics, problems may occur concerning the transport and storage of insulin, as well as control of glycaemia, all caused by irregularity of meals, variable diet, physical activity, stress, kinetosis (sea voyages), and the change of time zones. The travel may as well evoke ailments caused by the change of climate and concomitant diseases such as traveller's diarrhoea, malaria, etc. Apart from avoiding glycaemia fluctuations, important for retaining health of diabetics is the prevention of other diseases and carrying the necessary drugs.

    One hundred twenty two meat samples confiscated from passengers on flights from non-European countries at the International Airport of Bilbao (Spain) were tested for the presence of the main foodborne viral pathogens (human noroviruses genogroups I and II, hepatitis A and E viruses) during 2012 and 2013. A sample process control virus, murine norovirus, was used to evaluate the correct performance of the method. Overall, 67 samples were positive for at least one enteric viruses, 65 being positive for hepatitis E virus (53.3%), 3 for human norovirus genogroup I (2.5%) and 1 for human norovirus genogroup II (0.8%), whereas hepatitis A virus was not detected in any sample. The type of positive meat samples was diverse, but mainly was pork meat products (64.2%). The geographical origin of the positive samples was wide and diverse; samples from 15 out 19 countries tested were positive for at least one virus. However, the estimated virus load was low, ranging from 55 to 9.0 × 10(4) PDU per gram of product. The results obtained showed the potential introduction of viral agents in travelers' luggage, which constitute a neglected route of introduction and transmission.

    Travel medicine deals with travellers' diseases. The target group is therefore distinct from tropical medicine. It has gained in significance due to the increase in tourism and professional work abroad in the last 50 years. Dangerous and widespread diseases in tropical countries, in particular tropical malaria, have come into focus in industrialized countries because of their appearance in travellers. Travel medicine deals not only with infectious or transmittable diseases, but also with the ability of patients with chronic diseases to travel, the medical aspects of flying, as well as the health hazards of professional work or high-risk sports abroad. The risk of disease as a result of travelling can be minimized by advice and prophylactic measures, such as vaccinations and drug prophylaxis against malaria, if indicated. On return, medical symptoms should be investigated promptly to ensure early detection of life-threatening disease courses, particularly tropical malaria, as well as to prevent the occurrence of small-scale epidemics. A small number of diseases can also emerge after several years, such as benign types of malaria, amoebic liver abscess and visceral leishmaniasis (kala-azar). Aids also belongs to these diseases. Therefore, in this era of HIV pandemic travellers concerned should be made aware of the risks.

    Full Text Available The study, part of the project "Atherosclerotic cardiovascular diseases, lipemic disorders, hypertension, obesity and diabetis mellitus in a population of the metropolitan area of the southeastern region of Brazil", had the following objectives: a the characterization and distribution among typical human socio-economic groupings, of the prevalence of some particular habits which constitute aspects of life-style-the use of tobacco, the use of alcohol and sedentary activity; b the establishment of the interrelation between the above-mentioned habits and some lipemic disorders. The prevalence of the habits cited behaved in the following manner: the use of tobacco predominated among men, distributed uniformly throughout the social strata; among the women the average percentage of smokers was 18,9%, a significant difference occurring among the highest socio-economic class, where the average was of 40.2%. The sedentary style of life presented high prevalence, among both men and women with exception of the women of the highest socio-economic level and of the skilled working class. The use of alcohol, as one would expect, is a habit basically practised by the men, without any statistically significant differences between classes. For the purpose of establishing associations between these risk fictors and lipemic conditions four situations were chosen, of the following characteristics: 1- total cholesterol > or = 220 mg/dl and triglycerides > or = 150 mg/dl; 2- HDL cholesterol or = 150 mg/dl; 3- HDL cholesterol or = 150 mg/dl, and the following independent variables: age, use of tobacco and the interactions between obesity and smoking, age and sedentary lifestyle, sex and obesity (R2=22%; the standardized B coefficient showed that the variables with the greatest weight in the forecasting of the variation in the levels of cholesterol were smoking and the interaction between obesity and smoking.

    This study was undertaken to (1) evaluate the potential contribution of high-temperature superconductors (HTSCs) to the technical and economic feasibility of magnetically levitated (maglev) vehicles, (2) determine the status of maglev transportation research in the United States and abroad, (3) identify the likelihood of a significant transportation market for high-speed maglev vehicles, and (4) provide a preliminary assessment of the potential energy and economic benefits of maglev systems. HTSCs should be considered as an enhancing, rather than an enabling, development for maglev transportation because they should improve reliability and reduce energy and maintenance costs. Superconducting maglev transportation technologies were developed in the United States in the late 1960s and early 1970s. Federal support was withdrawn in 1975, but major maglev transportation programs were continued in Japan and West Germany, where full-scale prototypes now carry passengers at speeds of 250 mi/h in demonstration runs. Maglev systems are generally viewed as very-high-speed train systems, but this study shows that the potential market for maglev technology as a train system, e.g., from one downtown to another, is limited. Rather, aircraft and maglev vehicles should be seen as complementing rather than competing transportation systems. If maglev systems were integrated into major hub airport operations, they could become economical in many relatively high-density US corridors. Air traffic congestion and associated noise and pollutant emissions around airports would also be reduced. 68 refs., 26 figs., 16 tabs.

    The objective was to determine the impact of a 1-year mixed strength-training programme on muscle function, functional ability, physical activity and life style. Twice-a-week hospital-based exercise classes and a once-a-week home session were conducted. Nineteen healthy community-dwelling training (T) men (76.6 +/- 3.1 years), 19 women (77.5 +/- 4.0 years) and 20 matched controls (C) participated in this study. Training was given with a two multi-gym machines for the lower limbs (Sitting calf and Leg press, TECHNOGYM, Italy) at 60% of the repetition maximum (1 RM) and at home it was with elastic bands. The following were the measurements made: muscle function-maximum isometric strength of the knee extensors (KE) and ankle plantar flexors (PF) measured with a Cybex Norm dynamometer, leg extensor power (LEP) with the Nottingham Power Rig; functional abilities-functional reach, chair rise, bed rise, 6-min walking test, stair climbing, get up and go, one-leg standing; physical activity-aerobic activities over 3 MET intensity (AA3), intensity classes; life-style-mean daily energy expenditure (MDEE). Significant gains in muscle function and functional abilities in both training females and males were observed, but females improved significantly more than males. Males (T + C) showed higher AA3 times than females (T + C) (P = 0.02), with females significantly more involved in light-intensity activities. We observed a 60% increase (t = 2.45) in AA3 time in T, but no increase in C. Trained males increased Class 2 physical activity time by 146% (t = 2.82) and trained females by 16% (t = 2.23). MDEE increased by 10% (t=2.62) in trained males. Our long-term mixed programme can improve muscle function and functional abilities in elderly females and functional abilities in males. It can positively affect the amount of habitual physical activity and the life-style of males and females over 75.

  1. Zero Energry Travel

    CERN Document Server

    Ahmad, Othman; Chekima, Ali

    2011-01-01

    It is fundamentally possible to travel with zero energy based on Newton Laws of Motion. According to the first law of motion, a body will continue to travel for infinite distance unless it is acted upon by another force. For a body in motion, the force which stops perpetual motion is friction. However, there are many circumstances that friction is zero, for example in space, where there is vacuum. On earth, gravity makes objects to be in constant contact with each other generating friction but technology exists to separate them in the air using powerful magnetic forces. At low speeds, the friction caused by air is minimal but we can create vacuum even on land for high speed travel. Another condition for travelling is for it to stop at its destination. On land, we can recover the kinetic energy back into electrical energy using brushless permanent magnet generators. These generators can also convert electric energy into kinetic energy in order to provide motion. This article reviews technologies that will allo...

    Provision of proper conditions for the creation of healthy life style is a priority of the state policy in this country with special attention given to the development of the mass physical culture and sports. The present paper contains information on the proportion of the population of the Russian Federation regularly engaged in physical culture and sports, provision of necessary sport facilities, and budgetary expenditures for the purpose in different constituent entities of the country. Public satisfaction with the conditions available for mass physical education and sports is discussed. Taking into account the low average life expectancy of the country's population and the increasing morbidity and traumaticity rates among the younger generation, it appears impossible to address the global challenge of improving the health of the nation without promotion of mass physical culture and sports and renewal of interest in these activities among the general population.

    The marine-derived Scopulariopsis brevicaulis strain LF580 produces scopularides A and B, which have anticancerous properties. We carried out genome sequencing using three next-generation DNA sequencing methods. De novo hybrid assembly yielded 621 scaffolds with a total size of 32.2 Mb and 16298 putative gene models. We identified a large non-ribosomal peptide synthetase gene (nrps1) and supporting pks2 gene in the same biosynthetic gene cluster. This cluster and the genes within the cluster are functionally active as confirmed by RNA-Seq. Characterization of carbohydrate-active enzymes and major facilitator superfamily (MFS)-type transporters lead to postulate S. brevicaulis originated from a soil fungus, which came into contact with the marine sponge Tethya aurantium. This marine sponge seems to provide shelter to this fungus and micro-environment suitable for its survival in the ocean. This study also builds the platform for further investigations of the role of life-style and secondary metabolites from S. brevicaulis. PMID:26505484

    Full Text Available Introduction: Overweight and primary obesity in children and adolescents is a crucial problem in public health. Obese children and adolescents are especially susceptible to obesity in adulthood and consequently exposed to many obesity related diseases. Objective: Evaluation of overweight and primary obesity in urban and rural youth populations and comparison of life style concerning: physical activity, sedentary behaviors, dietary habits among overweight and obese adolescents and their peers with proper Body Mass Index value. Materials and methods: The study was performed in the group of 136 students from junior high school. The students with BMI value over 85th percentile of sex-specific growth charts were classified as overweight. Research tool was a questionnaire. Results: 15,9% of adolescents were overweight, out of which 4,5% were obese. There was not a significant relation between Body Mass Index and the place of residence. Overweight and obese adolescents revealed lower physical activity and tendency to spend much more time playing computer games. Adolescents with overweight or obesity did not regularly have breakfast at weekends, more often had sweets and sweet drinks and also high energy and very salty snacks instead. Conclusions: Overweight and obesity is a serious problem among students from junior high school population which calls for taking immediate preventive measures to promote healthy lifestyle among children and adolescents.

    AIM: To determine the prevalence of Helicobacter pylori (H pylori) among dyspeptic patients and to assess the relationship between H pylori infection, blood group, HIV infection and life style of the patients.METHODS: In a hospital-based cross-sectional study,patients attending Outpatient Department of University of Gondar Hospital were enrolled. Socio-demographic information was collected using questionnaires. Serum was analyzed for anti-H pylori IgG antibodies using a commercial kit. HIV serostatus was determined by enzyme-linked immunosorbent assay (ELISA). Blood grouping was performed by slide agglutination tests.RESULTS: A total of 215 dyspeptic patients were included in the study. One hundred and sixteen patients (54%) were females and 99 (46%) were males. Anti-H pylori IgG antibodies were detected in sera of 184 (85.6%) patients. The prevalence was significantly higher in patients aged 50 years and above. Twenty point five percent of the patients were found to be seropositive for HIV. No significant association was found between sex,ABO blood groups, consumption of spicy diets, socioeconomic status and seropositivity for H pylori. However,alcohol consumption was significantly associated with H pylori serology.CONCLUSION: The prevalence of H pylori infection is associated with a history of alcohol intake and older age.The effect of different diet, alcohol and socioeconomic status as risk factors for H pylori infection needs further study.

    The objectives of this study were to assess both the predisposing and precipitating risk factors in the aetiology of any form of cancer among hospital workers at two teaching Hospitals in Osun State, Nigeria. Pre-tested and modified questionnaires were administered to 250 respondents. One hundred and seventy questionnaires were duly filled and completed. Less than 9% of the respondents consumed fruits and vegetables on a daily basis; while the highest percentage (65%) regularly consumed butter/margarine, followed with consumption of red meat. Twenty nine percent (29%) from both locations were classified as overweight and obese. Half did physical exercise twice a week. Of the 168 respondents. 34 (20.2%) did meet the criteria for completely emptying their bowels within a specified time of three minutes. It is concluded that whilst predisposing risk factors do not pose a threat to the onset of any form of cancer among respondents, precipitating factors are real major factors that need to be addressed through information, education and communication (I.E.C). Such an I.E.C. should be geared towards promotion of healthy eating and life style strategies. Alter all, 'the first step in cancer prevention is knowing the risk profile'.

    Full Text Available Abstract Background The growing popularity of CAM among the public is coupled with an ongoing debate on its effectiveness, safety, and its implications on the reimbursement system. This issue is critically important for GPs, who have a "gatekeeping" role with respect to health care expenditure. GPs must be aware of medications' uses, limitations and possible adverse effects. Our objective was to explore GPs' knowledge of CAM and patterns of recommendation and practice, as well as the relationship between such patterns and GPs' life-styles. Methods A cross-sectional study was conducted in Tuscany, a region of central Italy. One hundred percent female GPs (498 and a 60% random sample of male GPs (1310 practising in the region were contacted through a self-administered postal questionnaire followed by a postal reminder and telephone interview. Results Overall response rate was 82.1%. Most respondents (58% recommended CAM but a far smaller fraction (13% practised it; yet 36% of CAM practitioners had no certificated training. Being female, younger age, practising in larger communities, having had some training in CAM as well as following a vegetarian or macrobiotic diet and doing physical activity were independent predictors of CAM recommendation and practice. However, 42% of GPs did not recommend CAM to patients mostly because of the insufficient evidence of its effectiveness. Conclusion CAM knowledge among GPs is not as widespread as the public demand seems to require, and the scarce evidence of CAM effectiveness hinders its professional use among a considerable number of GPs. Sound research on CAM effectiveness is needed to guide physicians' behaviour, to safeguard patients' safety, and to assist policy-makers in planning regulations for CAM usage.

    1995-03-01

    Background: European air travelers returning from Algeria, Egypt, Mexico, Morocco, and Tunisia were interviewed about their experience of travelers' diseases upon arrival in Brussels. Diarrhea was mentioned by 37% of the adults and 27% of the children. These subjects were questioned about the types of measures taken, type and duration of drug treatment (if any), and about duration of diarrhea and side effects experienced. Methods: Final analysis was performed based on 2160 interviews. The largest proportion of diarrhea was reported in the age group 15-24 years (46%). Results: The majority of the 2160 subjects had opted for drug treatment (81%): 927 subjects for loperamide alone, 235 for loperamide in combination with nifuroxazide, and 178 for nifuroxazide alone. Other drugs had been used less frequently. The median time to recovery was 2.4 days with loperamide compared to 3.2 days with nifuroxazide and to 3.4 days for the no-treatment group. Conclusions: A stratification of the results by severity of the diarrhea suggests a rank of antidiarrheal potency as follows: loperamide > nifuroxazide > no-drug treatment. The side effect with the highest incidence was constipation (2.4% with loperamide). (J Travel Med 2:11-15, 1995) Travelers' diarrhea is usually defined as the passage of at least three unformed stools per day or any number of such stools when accompanied by fever, abdominal cramping, or vomiting. The definition may be broadened to include more trivial bowel disturbance.1,2 The duration of this self-limited disease generally is 3 to 5 days. Medical intervention aims at shortening the duration of disease, thus allowing the sufferer to resume his or her usual activities at an early stage. A shortened period of recovery to physical well-being has obvious favorable economic implications if the traveler is on business and may help the maintenance of a desired level of quality of life while a traveler is on holiday.

Examples of recent gene duplication events in signaling as well as dioxygenase clusters are present, indicating selective gene family expansion as a relatively recent event in D. aromatica's evolutionary history. Gene families that constitute metabolic cycles presumed to create D. aromatica's environmental 'foot-print' indicate a high level of diversification between its predicted capabilities and those of its close relatives, A. aromaticum str EbN1 and Azoarcus BH72.

    Initial interest in Dechloromonas aromatica strain RCB arose from its ability to anaerobically degrade benzene. It is also able to reduce perchlorate and oxidize chlorobenzoate, toluene, and xylene, creating interest in using this organism for bioremediation. Little physiological data has been published for this microbe. It is considered to be a free-living organism. The a priori prediction that the D. aromatica genome would contain previously characterized 'central' enzymes involved in anaerobic aromatic degradation proved to be false, suggesting the presence of novel anaerobic aromatic degradation pathways in this species. These missing pathways include the benzyl succinyl synthase (bssABC) genes (responsible for formate addition to toluene) and the central benzoylCoA pathway for monoaromatics. In depth analyses using existing TIGRfam, COG, and InterPro models, and the creation of de novo HMM models, indicate a highly complex lifestyle with a large number of environmental sensors and signaling pathways, including a relatively large number of GGDEF domain signal receptors and multiple quorum sensors. A number of proteins indicate interactions with an as yet unknown host, as indicated by the presence of predicted cell host remodeling enzymes, effector enzymes, hemolysin-like proteins, adhesins, NO reductase, and both type III and type VI secretory complexes. Evidence of biofilm formation including a proposed exopolysaccharide complex with the somewhat rare exosortase (epsH), is also present. Annotation described in this paper also reveals evidence for several metabolic pathways that have yet to be observed experimentally, including a sulphur oxidation (soxFCDYZAXB) gene cluster, Calvin cycle enzymes, and nitrogen fixation (including RubisCo, ribulose-phosphate 3-epimerase, and nif gene families, respectively). Analysis of the D. aromatica genome indicates there is much to be learned regarding the metabolic capabilities, and life-style, for this microbial

A thorough pretravel health assessment will offer patients and health care providers valuable information for anticipatory guidance before travel. The destination-based risk assessment will help determine the risks involved in travel to specific locations and guide in the development of contingency plans for all travelers, especially those with chronic conditions. Diseases are more prevalent overseas, and immunizations and vaccinations are all important considerations for persons traveling abroad.

    Gautret, Philippe; Parola, Philippe

    2014-03-01

    Most cases of rabies in travelers are associated with dog bites and occur in adults who are commonly migrants. The incidence of injuries to travelers caused by potentially rabid animals is approximately 0.4 % per month of stay. Dogs account for 51 % of cases, but nonhuman primates are the leading animals responsible for injuries in travelers returning from Southeast Asia. Travel to Southeast Asia, India and North Africa, young age, and traveling for tourism are risk factors for potential exposure. More than 70 % of travelers are not immunized prior to departing and do not receive adequate care when injured. The intradermal vaccination route has been proven economical, safe and immunogenic in travelers. The immunity provided by the three-dose series is long-lasting and should be considered an investment for future travel. Abbreviated schedules may be used for last-minute travelers.

    I denne oppgaven har vi forsket rundt hvorvidt en relativt ny distribusjonskanal som AirBnb kan komme til å påvirke hotellbransjen. Konsumenter er mer prisbevisste enn før og har større oppfatning om verdi. At hotellene har kjennskap til verdi er derfor viktig for å kunne holde tritt med det som skjer på markedet og for å kunne stå i konkurransen. Vår problemstilling er derfor «Hva må hotellene ta for seg for å konkurrere mot fordelene som AirBnb gir?». For å besvare problemstillingen h...

    for both strains is AHL-independent. In addition, QS in G3 positively regulated antifungal activity, production of exoenzymes, but negatively regulated production of indol-3-acetic acid (IAA, which is in agreement with previous reports in strain HRO-C48. However, in contrast to HRO-C48, swimming motility was not controlled by AHL-mediated QS. Conclusions This is the first report of the characterisation of two AHL-based quorum sensing systems in the same isolate of the genus Serratia. Our results show that the QS network is involved in the global regulation of biocontrol-related traits in the endophytic strain G3. However, although free-living and endophytic S. plymuthica share some conservation on QS phenotypic regulation, the control of motility and biofilm formation seems to be strain-specific and possible linked to the life-style of this organism.

    Pust, R E; Peate, W F; Cordes, D H

    1986-12-01

    Travel, especially if it is international, often means major changes for the family. Family physicians should assess the epidemiologic risk and psychosocial significance of travel or relocation in light of the family's life-cycle stage and antecedent health. Using core references, which are kept current in partnership with public health agencies, family physicians are able to provide comprehensive immunization, medications, and patient education for all travel risks. Families are given medical record summaries and recommended sources of care at their destination. Eight weeks after their return patients are reassessed for newly acquired illness and helped to integrate the perspectives gained during the travel into the family's future dynamics. Taking advantage of growing travel medicine opportunities, family medicine educators should base the care of travelers and teaching of residents on defined competence priorities. Travelers' health provides a mutually rewarding model of shared care with public health consultants in the community medicine curriculum.

  18. The Effect of Corporate Influence in the Short Haul Business Travel Market

    Science.gov (United States)

    Mason, Keith J.

    1999-01-01

    The importance of corporate involvement in the decision making process for business related air travel is being increasingly recognised in the literature. Business travellers consume air services (i.e. they take airline flights), however; they may not be the principal decision-maker in the purchase. Also it is the organization that employs the traveller that incurs die cost for air travel. Consequently this research addresses the relationship between the traveller and the employing organisation in the purchase of air travel. In this paper traveller opinions on their corporate travel policy are evaluated using a Likert summated rating scale. The benefits sought, by the traveller, from the air service are also investigated and these benefits are used to segment the short haul business air travel market in the EU. Changes in the market for short haul business travel since the full liberalisation of the aviation market in-the EU are evaluated by comparing the data to an earlier study of similar travellers in 1992.

    2015-06-01

    Histoplasmosis is a common endemic human mycoses acquired mostly in the Americas. We reviewed 23 cases of histoplasmosis in Israeli travelers; 22 had traveled to Central or South America and one to North America. Fourteen cases had been exposed to bat habitats and were symptomatic, presenting ≤ 3 months after their return. Asymptomatic patients (N = 9) were diagnosed during the evaluation of incidental radiological findings or because a travel partner had been suspected of Histoplasma infection, 16-120 months after their return. Serological testing was positive in 75% of symptomatic cases but only 22% of asymptomatic cases. Histoplasmosis should be considered in travelers returning from the Americas with respiratory or febrile illness within weeks of return, particularly if exposed to bat habitats. Travel history is essential in patients presenting with pulmonary nodules, even years after travel to endemic countries.

    of travel time savings (VTTS). The final model, which was formulated as a nested logit model and included Box–Cox transformed travel time and cost attributes, revealed several interesting findings. Firstly, we found damping effects in both cost and time – most strongly in cost. Secondly, we found...... significant interactions among travel cost and time, and journey characteristics, such as distance and duration. This had direct impact on the VTTS, which was shown to decrease with distance and duration. Thirdly, we found that air travel implies a higher average VTTS, which is to be expected but rarely......The geographical scope of travel varies from short distances in urban areas to long distances across cities and countries. While urban travel has been widely analysed in the literature, travel over longer distances and particularly across countries, has received much less attention. While this may...

    Castelli, F; Carosi, G

    1995-01-01

    Annually, over 75 million international passengers travel to tropical areas, more than 20 million of whom come from industrialized countries. They experience a high rate of traveler's diarrhea (TD), varying from 20 to 56%, which may result in serious limitations to their activities. The cause of TD is considered to be infectious in the overwhelming majority of cases and, apart from differences in relative importance, the list of responsible microbial agents is fairly constant regardless of geographic origin. The ingestion of contaminated food or water is considered to be the principal mode of transmission of the enteric pathogens of TD. Several factors have been proposed as playing a role in the etiogenesis of diarrhea in travelers, including personal (age, socioeconomic status, body weight, preexisting gastrointestinal illnesses), behavioral (mode of travel, standard of accommodation, eating in public places, dietary errors) and travel-related (destination, duration of stay, country of origin, season) factors, which are reviewed in detail.

    The traveling-wave photodetector of the present invention combines an absorptive optical waveguide and an electrical transmission line, in which optical absorption in the waveguide results in a photocurrent at the electrodes of the electrical transmission line. The optical waveguide and electrical transmission line of the electrically distributed traveling-wave photodetector are designed to achieve matched velocities between the light in the optical waveguide and electrical signal generated on the transmission line. This velocity synchronization provides the traveling-wave photodetector with a large electrical bandwidth and a high quantum efficiency, because of the effective extended volume for optical absorption. The traveling-wave photodetector also provides large power dissipation, because of its large physical size.

  5. Travel patterns in China.

    Directory of Open Access Journals (Sweden)

    Tini Garske

    Full Text Available The spread of infectious disease epidemics is mediated by human travel. Yet human mobility patterns vary substantially between countries and regions. Quantifying the frequency of travel and length of journeys in well-defined population is therefore critical for predicting the likely speed and pattern of spread of emerging infectious diseases, such as a new influenza pandemic. Here we present the results of a large population survey undertaken in 2007 in two areas of China: Shenzhen city in Guangdong province, and Huangshan city in Anhui province. In each area, 10,000 randomly selected individuals were interviewed, and data on regular and occasional journeys collected. Travel behaviour was examined as a function of age, sex, economic status and home location. Women and children were generally found to travel shorter distances than men. Travel patterns in the economically developed Shenzhen region are shown to resemble those in developed and economically advanced middle income countries with a significant fraction of the population commuting over distances in excess of 50 km. Conversely, in the less developed rural region of Anhui, travel was much more local, with very few journeys over 30 km. Travel patterns in both populations were well-fitted by a gravity model with a lognormal kernel function. The results provide the first quantitative information on human travel patterns in modern China, and suggest that a pandemic emerging in a less developed area of rural China might spread geographically sufficiently slowly for containment to be feasible, while spatial spread in the more economically developed areas might be expected to be much more rapid, making containment more difficult.

    2013-06-01

    The need for athletes to travel long distances has spurred investigation into the effect of air travel across multiple time zones on athletic performance. Rapid eastward or westward travel may negatively affect the body in many ways; therefore, strategies should be employed to minimise these effects which may hamper athletic performance. In this review, the fundamentals of circadian rhythm disruption are examined along with additional effects of airline travel including jet lag, sleep deprivation, travel at altitude and nutritional considerations that negatively affect performance. Evidence-based recommendations are provided at the end of the manuscript to minimise the effects of airline travel on performance.

  11. Patterns of measles transmission among airplane travelers.

    Science.gov (United States)

    Edelson, Paul J

    2012-09-01

    With advanced air handling systems on modern aircraft and the high level of measles immunity in many countries, measles infection in air travelers may be considered a low-risk event. However, introduction of measles into countries where transmission has been controlled or eliminated can have substantial consequences both for the use of public health resources and for those still susceptible. In an effort to balance the relatively low likelihood of disease transmission among largely immune travelers and the risk to the public health of the occurrence of secondary cases resulting from importations, criteria in the United States for contact investigations for measles exposures consider contacts to be those passengers who are seated within 2 rows of the index case. However, recent work has shown that cabin air flow may not be as reliable a barrier to the spread of measles virus as previously believed. Along with these new studies, several reports have described measles developing after travel in passengers seated some distance from the index case. To understand better the potential for measles virus to spread on an airplane, reports of apparent secondary cases occurring in co-travelers of passengers with infectious cases of measles were reviewed. Medline™ was searched for articles in all languages from 1946 to week 1 of March 2012, using the search terms "measles [human] or rubeola" and ("aircraft" or "airplane" or "aeroplane" or "aviation" or "travel" or "traveler" or "traveller"); 45 citations were returned. Embase™ was searched from 1988 to week 11 2012, using the same search strategy; 95 citations were returned. Papers were included in this review if they reported secondary cases of measles occurring in persons traveling on an airplane on which a person or persons with measles also flew, and which included the seating location of both the index case(s) and the secondary case(s) on the plane. Nine reports, including 13 index cases and 23 apparent secondary cases

  13. [Malaria and travelers: protection and information].

    Science.gov (United States)

    Baudon, D; Martet, G

    1997-01-01

    With the increasing drug resistance of Plasmodium falciparum especially to agents used for chemoprophylaxis, every precaution must be taken to protect travelers from contracting malaria. Prevention of mosquito bites is a fundamental goal that can be achieved by a variety of means including pyrethrinoid-impregnated bed nets, insecticide strips, liquid vaporizers, repellents, insecticide-impregnated garments, and air-conditioning. There are no contraindications for vector control. Chemoprophylaxis depends of individual criteria as determined by clinical and laboratory examinations and on travel conditions (destination, season, duration of stay, and local living conditions). Stand-by medication should be prescribed for self-treatment of fever in areas where medical care is not readily available. Chemoprophylaxis must be continued after the traveler returns and medical attention should be sought if symptoms occur. To ensure proper compliance with preventive measures, pre-travel counseling is a mandatory and integral part of prevention. Information provided to travelers must be clear, reliable, and up-to-date.

  14. Risk assessment in travel medicine.

    Science.gov (United States)

    Leggat, Peter A

    2006-01-01

    Risk assessment is an integral part of pre-travel and post- assessment. Risk assessment largely determines what health and safety advice and interventions are given within the relevant prevailing travel health guidelines. Risk assessment needs time and depends on information, including that given by the traveller. Risk assessment also needs to be documented. Risk assessment of the traveller preferably starts before they enter the consulting room, where travellers may complete a pre-travel health questionnaire. Armed with this information, risk assessment may be assisted by access to computerised travel health databases and the published literature. Experience of travel to the destination may also assist in risk assessment and the tour operator, overseas employer or agency, the traveller or even the travel health advisers themselves may provide this information.

  15. The travel-related carbon dioxide emissions of atmospheric researchers

    Science.gov (United States)

    Stohl, A.

    2008-11-01

    Most atmospheric scientists agree that greenhouse gas emissions have already caused significant changes to the global climate system and that these changes will accelerate in the near future. At the same time, atmospheric scientists who like other scientists rely on international collaboration and information exchange travel a lot and, thereby, cause substantial emissions of CO2. In this paper, the CO2 emissions of the employees working at an atmospheric research institute (the Norwegian Institute for Air Research, NILU) caused by all types of business travel (conference visits, workshops, field campaigns, instrument maintainance, etc.) were calculated for the years 2005 2007. It is estimated that more than 90% of the emissions were caused by air travel, 3% by ground travel and 5% by hotel usage. The travel-related annual emissions were between 1.9 and 2.4 t CO2 per employee or between 3.9 and 5.5 t CO2 per scientist. For comparison, the total annual per capita CO2 emissions are 4.5 t worldwide, 1.2 t for India, 3.8 t for China, 5.9 t for Sweden and 19.1 t for Norway. The travel-related CO2 emissions of a NILU scientist, occurring in 24 days of a year on average, exceed the global average annual per capita emission. Norway's per-capita CO2 emissions are among the highest in the world, mostly because of the emissions from the oil industry. If the emissions per NILU scientist derived in this paper are taken as representative for the average Norwegian researcher, travel by Norwegian scientists would nevertheless account for a substantial 0.2% of Norway's total CO2 emissions. Since most of the travel-related emissions are due to air travel, water vapor emissions, ozone production and contrail formation further increase the relative importance of NILU's travel in terms of radiative forcing.

    The multiple traveling salesman problem (MTSP) is an important combinatorial optimization problem. It has been widely and successfully applied to the practical cases in which multiple traveling individuals (salesmen) share the common workspace (city set). However, it cannot represent some application problems where multiple traveling individuals not only have their own exclusive tasks but also share a group of tasks with each other. This work proposes a new MTSP called colored traveling salesman problem (CTSP) for handling such cases. Two types of city groups are defined, i.e., each group of exclusive cities of a single color for a salesman to visit and a group of shared cities of multiple colors allowing all salesmen to visit. Evidences show that CTSP is NP-hard and a multidepot MTSP and multiple single traveling salesman problems are its special cases. We present a genetic algorithm (GA) with dual-chromosome coding for CTSP and analyze the corresponding solution space. Then, GA is improved by incorporating greedy, hill-climbing (HC), and simulated annealing (SA) operations to achieve better performance. By experiments, the limitation of the exact solution method is revealed and the performance of the presented GAs is compared. The results suggest that SAGA can achieve the best quality of solutions and HCGA should be the choice making good tradeoff between the solution quality and computing time.

    Consultation of child traveler has two main objectives: to assess of health risk related to the child's health status and history and also the risk related to travel environment; to counsel and prescribe preventive measure to reduce these travel health risks. The evaluation is based on physical examination and a detailed interview including personal history and information regarding the regions of proposed travel. Up to date knowledge of the epidemiology of visited sites, preventive measures and presumptive treatment is required. Essential health recommendations include, in case of exposure, prevention of malaria, arthropod borned diseases and vaccine preventable diseases. For all destinations advice regarding prevention of diarrhea, accident risks and aggravation of preexisting chronic diseases is needed. Universal primary prevention counselling is valuable for all travellers regardless of their age. In the case of children, special attention must be given to food and water hygiene, sun and heat exposure, swimming risks and transports security measures. Evaluation of risk and health education take time and often several visits are needed to complete the immunization schedule before departure.

    The planning for surgery in war was revisited in 1937 when Ian Fraser was elected a member of the Surgical Travellers. At their 1938 Surgical Travellers meeting in Vienna, Ian and Eleanor Fraser were evicted from their hotel room by the Nazis. The 1939 meeting in Belfast discussed the organization of surgery and the conduct of Emergency Medical Service Hospitals in the United Kingdom; the vast majority were to be under civilian government and military control. From 1943 lengthy and informative organizational meetings were held at least monthly under the chairmanship of Sir Alexander Hood, KBE, Head of the RAMC. Surgical Consultants, now Major Generals, Brigadiers or Full Colonels in the British and U.S. Armies stationed in the UK, prepared for the invasion of Europe. The allocation of medical, surgical, nursing and auxiliary responsibilities was delineated. Liaison with the RAF and US Army Air Force was close as it was with the proposed leaders, Ulstermen Brooke and Montgomery. Montgomery chose Arthur Porritt as Surgeon in Chief to Supreme Headquarters Allied Expeditionary Force (SHAEF), and Eisenhower, General Albert W. Kenner. Just after D-Day, Porritt met Ian Fraser, who had waded in on Arromanches Beach. The triage and evacuation plans for Allied casualties had been controversial, particularly as regards Landing Ship Tanks (LSTs). The dispute with the Hood-selected surgeons on one side, against medical and surgical deployment of LSTs, and Admiral Ernest King and Winston Churchill on the other, favouring LST use for surgery and evacuation. King and Churchill were correct but total Allied air superiority allowed wide use of many of the Allies' Dakotas; 10,000 DC-3s were eventually in service. Supported by forty Allied combat planes to each Luftwaffe, the dispute about Landing Ship Tank use in about a fortnight became moot.

    2009-03-01

    The second trimester is the safest time for travelling, because the pregnant woman feels generally most at ease and the risk of spontaneous abortion and pre-term labour is very low. Possible risks must be discussed with the obstetrician before travelling. If the pregnancy is uncomplicated most airlines allow flying up to the 36th (domestic flights) and 35th (international flights) week of gestation. Unless the fetal oxygen supply is already impaired at ground level due to an underlying disease, flying does not pose a risk of fetal hypoxia. Radiation exposure during a long distant flight is low compared to the average annual exposure dosage, but the risk of thrombosis is increased. Altitudes up to 2,500 m pose no problem. Sufficient time to acclimatize must be taken when travelling to high altitudes and exercise kept to a minimum. Scuba diving is contraindicated. Since only a few drugs are completely safe during pregnancy a thorough risk/benefit evaluation is mandatory. Treatment of infections can be considerably complicated, but any necessary treatment should not be withheld because of the fear of potential fetal injury. Good knowledge of local medical resources is essential before travelling. Several personal protective measures minimize the risk of infection: food and water precautions, protection from insect bites and avoidance of crowds, unsafe sex and, if need be, freshwater. Many vaccinations are recommended for travellers. However, live vaccines are contraindicated in pregnant women because of theoretical considerations. Exceptionally a yellow fever vaccination may be given after the first trimester. Killed, inactivated or polysaccharide vaccines can be given after the first trimester after a thorough risk/benefit evaluation. Because of the potentially devastating effect of malaria to the mother and the child, travelling to endemic malaria regions should be avoided. If the risk of infection is high chemoprophylaxis with mefloquine is indicated. In low

    1998-06-01

    As travel has become easier and more affordable, the number of people traveling has risen sharply. People travel for many and varied reasons, from the business person on an overseas assignment to backpackers seeking new and exotic destinations. Others may take up residence in different regions, states or countries for family, business or political reasons. Other people are fleeing religious or political persecution. Wherever they go and for whatever reason they go, people take their culture with them. Culture, like language, is acquired innately in early childhood and is then reinforced through formal and complex informal social education into adulthood. Culture provides a framework for interpersonal and social interactions. Therefore, the contact with a new culture is often not the exciting or pleasurable experience anticipated. When immersed in a different culture, people no longer know how to act when faced with disparate value systems. Contact with the unfamiliar culture can lead to anxiety, stress, mental illness and, in extreme cases, physical illness and suicide. "Culture shock" is a term coined by the anthropologist Oberg. It is the shock of the new. It implies that the experience of the new culture is an unpleasant surprise or shock, partly because it is unexpected and partly because it can lead to a negative evaluation of one's own culture. It is also known as cross-cultural adjustment, being that period of anxiety and confusion experienced when entering a new culture. It affects people intellectually, emotionally, behaviorally and physically and is characterized by symptoms of psychological distress. Culture shock affects both adults and children. In travelers or workers who have prolonged sojourns in foreign countries, culture shock may occur not only as they enter the new culture, but also may occur on their return to their original culture. Children may also experience readjustment problems after returning from leading sheltered lives in expatriate

    2012-09-01

    A common approach to malaria prevention is to follow the "A, B, C, D" rule: Awareness of risk, Bite avoidance, Compliance with chemoprophylaxis, and prompt Diagnosis in case of fever. The risk of acquiring malaria depends on the length and intensity of exposure; the risk of developing severe disease is primarily determined by the health status of the traveler. These parameters need to be assessed before recommending chemoprophylaxis and/or stand-by emergency treatment. This review discusses the different strategies and drug options available for the prevention of malaria during and post travel.

    Science.gov (United States)

    Carroll, Bernadette; Daniel, Amanda; Behrens, Ron H

    The health threats of modern day travel change as population, wealth and tourism increase across the world. A series of three articles have been written to describe the spectrum of health issues associated with travel. Pre-travel health advice has become more focused on risk assessment and educating the traveller about infectious disease and the more frequent non-infectious hazards associated with travel, while ensuring they are not unnecessarily exposed to injury from vaccines and drugs. In part one, the role of the health advisor and the needs of the traveller are examined. The importance of risk assessment during a consultation is described and factors that influence recommendations and prescribing are explored. As most travel-associated morbidity and mortality is non-vaccine preventable, the focus of the pre-travel consultation should be on educating the traveller and influencing behaviour change. The second article in this series deals with the highest risk group of travellers--residents who visit friends and relatives. It highlights their specific problems and special needs and how to influence their risk of disease by addressing their health beliefs and their cultural dimension of risk. The third article explores the common, and not so common, clinical problems found in returned travellers. Nurses have to deal with a large range of clinical problems and diagnostic dilemmas when attending to the returned traveller. The review provides a perspective on the frequency and severity of problems and how nurses should manage travel associated disease.

  7. Unsteady planar diffusion flames: Ignition, travel, burnout

    Science.gov (United States)

    Fendell, F.; Wu, F.

    1995-01-01

    In microgravity, a thin planar diffusion flame is created and thenceforth travels so that the flame is situated at all times at an interface at which the hydrogen and oxygen meet in stoichiometric proportion. If the initial amount of hydrogen is deficient relative to the initial amount of oxygen, then the planar flame will travel further and further into the half volume initially containing hydrogen, until the hydrogen is (virtually) fully depleted. Of course, when the amount of residual hydrogen becomes small, the diffusion flame is neither vigorous nor thin; in practice, the flame is extinguished before the hydrogen is fully depleted, owing to the finite rate of the actual chemical-kinetic mechanism. The rate of travel of the hydrogen-air diffusion flame is much slower than the rate of laminar flame propagation through a hydrogen-air mixture. This slow travel facilitates diagnostic detection of the flame position as a function of time, but the slow travel also means that the time to burnout (extinction) probably far exceeds the testing time (typically, a few seconds) available in earth-sited facilities for microgravity-environment experiments. We undertake an analysis to predict (1) the position and temperature of the diffusion flame as a function of time, (2) the time at which extinction of the diffusion flame occurs, and (3) the thickness of quench layers formed on side walls (i.e., on lateral boundaries, with normal vectors parallel to the diffusion-flame plane), and whether, prior to extinction, water vapor formed by burning will condense on these cold walls.

    Policy makers rely on transportation statistics, including data on personal travel behavior, to formulate strategic transportation policies, and to improve the safety and efficiency of the U.S. transportation system. Data on personal travel trends are needed to examine the reliability, efficiency, capacity, and flexibility of the Nation's transportation system to meet current demands and to accommodate future demand. These data are also needed to assess the feasibility and efficiency of alternative congestion-mitigating technologies (e.g., high-speed rail, magnetically levitated trains, and intelligent vehicle and highway systems); to evaluate the merits of alternative transportation investment programs; and to assess the energy-use and air-quality impacts of various policies. To address these data needs, the U.S. Department of Transportation (USDOT) initiated an effort in 1969 to collect detailed data on personal travel. The 1969 survey was the first Nationwide Personal Transportation Survey (NPTS). The survey was conducted again in 1977, 1983, 1990, 1995, and 2001. Data on daily travel were collected in 1969, 1977, 1983, 1990 and 1995. In 2001, the survey was renamed the National Household Travel Survey (NHTS) and it collected both daily and long-distance trips. The 2001 survey was sponsored by three USDOT agencies: Federal Highway Administration (FHWA), Bureau of Transportation Statistics (BTS), and National Highway Traffic Safety Administration (NHTSA). The primary objective of the survey was to collect trip-based data on the nature and characteristics of personal travel so that the relationships between the characteristics of personal travel and the demographics of the traveler can be established. Commercial and institutional travel were not part of the survey. Due to the survey's design, data in the NHTS survey series were not recommended for estimating travel statistics for categories smaller than the combination of Census division (e.g., New

    Tang, Ming; Liu, Zonghua; Li, Baowen

    2009-07-01

    A fundamental feature of agent traveling in social networks is that traveling is usually not a random walk but with a specific destination and goes through the shortest path from starting to destination. A serious consequence of the objective traveling is that it may result in a fast epidemic spreading, such as SARS etc. In this letter we present a reaction-traveling model to study how the objective traveling influences the epidemic spreading. We consider a random scale-free meta-population network with sub-population at each node. Through a SIS model we theoretically prove that near the threshold of epidemic outbreak, the objective traveling can significantly enhance the final infected population and the infected fraction at a node is proportional to its betweenness for the traveling agents and approximately proportional to its degree for the non-traveling agents. Numerical simulations have confirmed the theoretical predictions.

    ABSTRACT Objective Few interventions have combined life-style and psychosocial approaches in the context of Type 2 diabetes management. The purpose of this study was to determine the effect of a multicomponent behavioral intervention on weight, glycemic control, renal function, and depressive symptoms in a sample of overweight/obese adults with Type 2 diabetes and marked depressive symptoms. Methods A sample of 111 adults with Type 2 diabetes were randomly assigned to a 1-year intervention (n = 57) or usual care (n = 54) in a parallel groups design. Primary outcomes included weight, glycosylated hemoglobin, and Beck Depression Inventory II score. Estimated glomerular filtration rate served as a secondary outcome. All measures were assessed at baseline and 6 and 12 months after randomization by assessors blind to randomization. Latent growth modeling was used to examine intervention effects on each outcome. Results The intervention resulted in decreased weight (mean [M] = 0.322 kg, standard error [SE] = 0.124 kg, p = .010) and glycosylated hemoglobin (M = 0.066%, SE = 0.028%, p = .017), and Beck Depression Inventory II scores (M = 1.009, SE = 0.226, p < .001), and improved estimated glomerular filtration rate (M = 0.742 ml·min−1·1.73 m−2, SE = 0.318 ml·min−1·1.73 m−2, p = .020) each month during the first 6 months relative to usual care. Conclusions Multicomponent behavioral interventions targeting weight loss and depressive symptoms as well as diet and physical activity are efficacious in the management of Type 2 diabetes.

    2012-04-01

    Cardiovascular diseases are mainly caused by atherosclerosis, the development of which is highly dependent on our Western lifestyle. Slowing this pathology depends on the reduction of risk factors such as hypercholesterolemia, high blood pressure, smoking, lack of physical activity, excess weight and diabetes. Drug treatment exists and is very effective, but too often they treat the immediate abnormality such as diabetes, high blood pressure and hypercholesterolemia and not the underlying causes: poor eating habits, lack of physical activity and excess weight. These have a negative impact on endothelial function, oxidative stress, and can trigger inflammation, arrythmias and thrombosis. Cardiovascular prevention must therefore target sedentary lifestyle, excess weight, and favor low-calorie, low-salt food and Mediterranean diet. The way this diet works begins to be understood and goes beyond simple cardiovascular prevention. Therapeutic education holds a growing and complementary role in the Public Health system which should call upon the strengths of all healthcare professionals.

    "Bucky Fuller thought big," Wired magazine recently noted, "Arthur C. Clarke thinks big, but Cliff Pickover outdoes them both." In his newest book, Cliff Pickover outdoes even himself, probing a mystery that has baffled mystics, philosophers, and scientists throughout history--What is the nature of time?In Time: A Traveler's Guide , Pickover takes readers to the forefront of science as he illuminates the most mysterious phenomenon in the universe--time itself. Is time travel possible? Is time real? Does it flow in one direction only? Does it have a beginning and an end? What is eternity? Pickover's book offers a stimulating blend of Chopin, philosophy, Einstein, and modern physics, spiced with diverting side-trips to such topics as the history of clocks, the nature of free will, and the reason gold glitters. Numerous diagrams ensure readers will have no trouble following along.By the time we finish this book, we understand a wide variety of scientific concepts pertaining to time. And most important, we will understand that time travel is, indeed, possible.

  15. [Traveling with small children].

    Science.gov (United States)

    Olivier, C

    1997-01-01

    Traveling with children especially in the tropics requires special planning. Contraindications are rare but care providers should obtain information about medical and transfusional facilities at the destination. Children should receive all vaccinations required for international travel and for specific countries, taking into account age, location, duration of stay, and purpose of trip. A first aid kit should be packed containing a thermometer, bandages, antiseptic agents, a total sunscreen preparation, a mosquito net, sterile compresses, tablets for water disinfection, and indispensable medications (antimalarial agents, antipyretics, oral rehydration solutions, antiemetics, and eye wash). The main indication for chemoprophylaxis is malaria. Chloroquine is recommended for most locations but proguanil may be necessary in areas of resistance. Special attention must be paid to skin care in infants: maintaining cleanliness, avoiding cuts insofar as possible, and treating any wounds. Clothing must be carefully laundered and adequate to prevent overexposure to sunlight and insect bites. Insect bites must also be prevented by applying repellents, using mosquito nets, and wearing insecticide-treated garments. Handwashing by people who prepare meals and by the children before eating is important to prevent food poisoning. Breast feeding is advisable for infants. Thorough cooking of meats, rinsing of fresh produce, drinking of bottled beverages, and sterilization of water are also important food safety measures. These precautions are usually adequate to allow safe travel with children.

    Carlson Wagonlit Travel wishes to remind you of the following conditions concerning travel to the USA. Passport conditions Since 26 October 2004, nationals of the countries covered by the US Visa Waiver Programme have been required to present a valid machine-readable passport when entering the United States. Failing this, they require a valid US non-immigrant visa in addition to their passport. Passports issued after 25 October 2005 must also bear a digital photograph. Passports issued after 25 October 2006 must contain biometric data to allow visa-free entry to the US. Advanced Passenger Information System (APIS) form Since 4 October 2005, all non-US citizens travelling to the USA have been required to complete the APIS form before departure and present it when they check in. This new procedure will certainly increase the time it takes to check in. We therefore advise passengers to present themselves at the respective check-in desk in good time.

    I investigate the relationship between faster-than-light travel and weak-energy-condition violation, i.e., negative energy densities. In a general spacetime it is difficult to define faster-than-light travel, and I give an example of a metric which appears to allow superluminal travel, but in fact is just flat space. To avoid such difficulties, I propose a definition of superluminal travel which requires that the path to be traveled reach a destination surface at an earlier time than any neig...

  19. Home range and travels

    Stickel, L.F.; King, John A.

    1968-01-01

    The concept of home range was expressed by Seton (1909) in the term 'home region,' which Burr (1940, 1943) clarified with a definition of home range and exemplified in a definitive study of Peromyscus in the field. Burt pointed out the ever-changing characteristics of home-range area and the consequent absence of boundaries in the usual sense--a finding verified by investigators thereafter. In the studies summarized in this paper, sizes of home ranges of Peromyscus varied within two magnitudes, approximately from 0.1 acre to ten acres, in 34 studies conducted in a variety of habitats from the seaside dunes of Florida to the Alaskan forests. Variation in sizes of home ranges was correlated with both environmental and physiological factors; with habitat it was conspicuous, both in the same and different regions. Food supply also was related to size of home range, both seasonally and in relation to habitat. Home ranges generally were smallest in winter and largest in spring, at the onset of the breeding season. Activity and size also were affected by changes in weather. Activity was least when temperatures were low and nights were bright. Effects of rainfall were variable. Sizes varied according to sex and age; young mice remained in the parents' range until they approached maturity, when they began to travel more widely. Adult males commonly had larger home ranges than females, although there were a number of exceptions. An inverse relationship between population density and size of home range was shown in several studies and probably is the usual relationship. A basic need for activity and exploration also appeared to influence size of home range. Behavior within the home range was discussed in terms of travel patterns, travels in relation to home sites and refuges, territory, and stability of size of home range. Travels within the home range consisted of repeated use of well-worn trails to sites of food, shelter, and refuge, plus more random exploratory travels

  1. Rabies vaccination for international travelers.

    Science.gov (United States)

    Gautret, Philippe; Parola, Philippe

    2012-01-05

    Rabies prevention in travelers is a controversial issue. According to experts, the decision to vaccinate results from an individual risk assessment based on the duration of stay, the likelihood of engagement in at-risk activities, the age of the traveler, the rabies endemicity and access to appropriate medical care in the country of destination. However, no detailed information is available regarding the last two determinants in many regions. Twenty-two cases of rabies were reported in tourists, expatriates and migrant travelers over the last decade, including three cases following short-term travel of no more than two weeks. Studies on rabies post-exposure prophylaxis (PEP) in travelers show that overall, 0.4% (range 0.01-2.3%) of travelers have experienced an at-risk bite per month of stay in a rabies-endemic country, while 31% of expatriates and 12% of tourists were vaccinated against rabies before traveling. The main reason cited by travelers for not being vaccinated is the cost of the vaccine. The majority of patients who sustained a high risk injury was not vaccinated against rabies before traveling and were not properly treated abroad. From available studies, the following risk factors for injuries sustained from potentially rabid animals may be identified: traveling to South-East Asia, India or North Africa, young age, and traveling for tourism. The duration of travel does not appear to be a risk factor. It should be noted that "at-risk activities" have not been addressed in these studies. Detailed rabies distribution maps and information on the availability of rabies biologics are urgently needed in order to identify those travelers who need pre-travel vaccination. Meanwhile, cost-minimization of rabies pre-exposure vaccination may be achieved in several ways, notably by using the intra-dermal method of vaccination.

    The impairment of mental time travel is a severe cognitive symptom in patients with brain lesions and a number of neuropsychiatric disorders. Whether animals are also able to mentally travel in time both forward and backward is still a matter of debate. In this regard, we have proposed a continuum of mental time travel abilities across different animal species, with humans being the species with the ability to perform most sophisticated forms of mental time travel. In this review and perspective article, we delineate a novel approach to understand the evolution, characteristics and function of human and animal mental time travel. Furthermore, we propose a novel approach to measure mental time travel in rodents in a comprehensive manner using a test battery composed of well-validated and easy applicable tests.

    The collapse of geographical space over the last 200 years has had profound effects on the circulation of human populations and on the transfer of infectious diseases. Three examples are used to illustrate the process: (a) the impact of the switch from sail to steamships in importing measles into Fiji over a 40-year period; (b) changes in measles epidemic behaviour in Iceland over a 150-year period; and (c) changes in the spread of cholera within the United States over a 35-year period. In each case, the link between time, travel and disease has been an intimate one.

  7. Beyond "medical tourism": Canadian companies marketing medical travel

    Directory of Open Access Journals (Sweden)

    2012-06-01

    Full Text Available Abstract Background Despite having access to medically necessary care available through publicly funded provincial health care systems, some Canadians travel for treatment provided at international medical facilities as well as for-profit clinics found in several Canadian provinces. Canadians travel abroad for orthopaedic surgery, bariatric surgery, ophthalmologic surgery, stem cell injections, “Liberation therapy” for multiple sclerosis, and additional interventions. Both responding to public interest in medical travel and playing an important part in promoting the notion of a global marketplace for health services, many Canadian companies market medical travel. Methods Research began with the goal of locating all medical tourism companies based in Canada. Various strategies were used to find such businesses. During the search process it became apparent that many Canadian business promoting medical travel are not medical tourism companies. To the contrary, numerous types of businesses promote medical travel. Once businesses promoting medical travel were identified, content analysis was used to extract information from company websites. Company websites were analyzed to establish: 1 where in Canada these businesses are located; 2 the destination countries and health care facilities that they market; 3 the medical procedures they promote; 4 core marketing messages; and 5 whether businesses market air travel, hotel accommodations, and holiday tours in addition to medical procedures. Results Searches conducted from 2006 to 2011 resulted in identification of thirty-five Canadian businesses currently marketing various kinds of medical travel. The research project began with what seemed to be the straightforward goal of establishing how many medical tourism companies are based in Canada. Refinement of categories resulted in the identification of eighteen businesses fitting the category of what most researchers would identify as medical tourism

    It has been demonstrated through numerical simulations using Lorentz forcing that spanwise travelling waves on turbulent wall flows can lead to a skin-friction drag reduction on the order of 30%. As an aeronautical application of this innovative flow control technique, we have investigated into the use of Dielectric-Barrier-Discharge (DBD) plasma actuators to generate spanwise travelling waves in air. The near-wall structures modified by the spanwise travelling waves were studied using the PIV technique in a wind tunnel, while the associated turbulence statistics were carefully documented using hot-wire anemometry. We observed the spreading of low-speed fluid by the spanwise travelling streamwise vortices, which seems to have greatly attenuated the turbulence production process. This is very much in line with the finding of DNS studies, where wide low-speed ribbons replaced the low-speed streaks.

    We conducted a prospective cohort study to assess adherence to malaria chemoprophylaxis, reasons for nonadherence, and use of other personal protective measures against malaria. We included adults traveling to malaria-endemic countries who were prescribed malaria chemoprophylaxis during a pre-travel consultation at three travel clinics in the Boston area and who completed three or more surveys: pre-travel, at least one weekly during travel, and post-travel (2–4 weeks after return). Of 370 participants, 335 (91%) took malaria chemoprophylaxis at least once and reported any missed doses; 265 (79%) reported completing all doses during travel. Adherence was not affected by weekly versus daily chemoprophylaxis, travel purpose, or duration of travel. Reasons for non adherence included forgetfulness, side effects, and not seeing mosquitoes. Main reasons for declining to take prescribed chemoprophylaxis were peer advice, low perceived risk, and not seeing mosquitoes. Of 368 travelers, 79% used insect repellent, 46% used a bed net, and 61% slept in air conditioning at least once. Because travelers may be persuaded to stop taking medication by peer pressure, not seeing mosquitoes, and adverse reactions to medications, clinicians should be prepared to address these barriers and to empower travelers with strategies to manage common side effects of antimalarial medications.

  12. Time travel a history

    Gleick, James

    2016-01-01

    From the acclaimed author of The Information and Chaos, here is a mind-bending exploration of time travel: its subversive origins, its evolution in literature and science, and its influence on our understanding of time itself. The story begins at the turn of the previous century, with the young H. G. Wells writing and rewriting the fantastic tale that became his first book and an international sensation: The Time Machine. It was an era when a host of forces was converging to transmute the human understanding of time, some philosophical and some technological: the electric telegraph, the steam railroad, the discovery of buried civilizations, and the perfection of clocks. James Gleick tracks the evolution of time travel as an idea that becomes part of contemporary culture—from Marcel Proust to Doctor Who, from Jorge Luis Borges to Woody Allen. He investigates the inevitable looping paradoxes and examines the porous boundary between pulp fiction and modern physics. Finally, he delves into a temporal shift that...

    Webb, G M; Ao, X; Zank, G P

    2013-01-01

    Models for travelling waves in multi-fluid plasmas give essential insight into fully nonlinear wave structures in plasmas, not readily available from either numerical simulations or from weakly nonlinear wave theories. We illustrate these ideas using one of the simplest models of an electron-proton multi-fluid plasma for the case where there is no magnetic field or a constant normal magnetic field present. We show that the travelling waves can be reduced to a single first order differential equation governing the dynamics. We also show that the equations admit a multi-symplectic Hamiltonian formulation in which both the space and time variables can act as the evolution variable. An integral equation useful for calculating adiabatic, electrostatic solitary wave signatures for multi-fluid plasmas with arbitrary mass ratios is presented. The integral equation arises naturally from a fluid dynamics approach for a two fluid plasma, with a given mass ratio of the two species (e.g. the plasma could be an electron pr...

  14. Traveling-Wave Tubes

    Kory, Carol L.

    1998-01-01

    The traveling-wave tube (TWT) is a vacuum device invented in the early 1940's used for amplification at microwave frequencies. Amplification is attained by surrendering kinetic energy from an electron beam to a radio frequency (RF) electromagnetic wave. The demand for vacuum devices has been decreased largely by the advent of solid-state devices. However, although solid state devices have replaced vacuum devices in many areas, there are still many applications such as radar, electronic countermeasures and satellite communications, that require operating characteristics such as high power (Watts to Megawatts), high frequency (below 1 GHz to over 100 GHz) and large bandwidth that only vacuum devices can provide. Vacuum devices are also deemed irreplaceable in the music industry where musicians treasure their tube-based amplifiers claiming that the solid-state and digital counterparts could never provide the same "warmth" (3). The term traveling-wave tube includes both fast-wave and slow-wave devices. This article will concentrate on slow-wave devices as the vast majority of TWTs in operation fall into this category.

    The telescope has been around for more than 400 years, and through good use of it scientists have made many astonishing discoveries and begun to understand our place in the universe. Most people, however, have never looked through one. Yet it is a great tool for cool science and observation especially in a continent and country with beautifully dark skies. The Travelling Telescope project aims to invite people outside under the stars to learn about those curious lights in the sky.The Travelling Telescope aims to promote science learning to a wide range of Kenyan schools in various locations exchanging knowledge about the sky through direct observations of celestial bodies using state of the art telescopes. In addition to direct observing we also teach science using various hands-on activities and astronomy software, ideal for explaining concepts which are hard to understand, and for a better grasp of the sights visible through the telescope. We are dedicated to promoting science using astronomy especially in schools, targeting children from as young as 3 years to the youth, teachers, their parents and members of the public. Our presentation focuses on the OAD funded project in rural coastal Kenya.

    2010-01-01

    Full Text Available Problem statement: A comparison of customer satisfaction based on service quality as perceived by air travelers was done among six domestic airlines. Literature review suggested that flying experience has three stages: Pre-flight, in-flight and post-flight and a set of six variables can be used to measure satisfaction. These variables are: Ease of bookings through the website/call center; Hassle free check in/efficient ticketing staff/regular announcements during flight delays at airport; on time performance of flights; in flight experience; baggage handling and value for money. Approach: A questionnaire was designed with above set of variables and responses of 150 fliers of six domestic airlines viz., GoAir, Kingfisher, Jet Airways, Indigo, SpiceJet and Air India (Domestic was recorded on a five point Likert scale. About 150 respondents were interviewed from different places in NCR: Delhi, Gurgaon, Noida, Greater Noida and Faridabad. A convenient sampling method was followed. Perceptions of only those travelers were captured who had actually undergone the experience of travelling by an airline. The range for the number of respondents was between 103 (for GoAir and 133 (for Jet Air. Results: Using one way ANOVA, it was checked whether travelers perceive any significant difference between six airlines for each of the above six identified variables. With Tukey-Kramer test the airlines which are significantly different from the rest were identified. Perceptual maps with combination of up to two variables (attributes were drawn to infer about the positioning of six different airlines. Conclusion: This study will help marketers of domestic airlines and designers of flight service offerings to enhance the satisfaction level of air travelers.

    Currently, there is no clear definition for the youth travel concept. This concept emerged much latter than the first forms of manifestation of tourism for young people, namely the beginning of the ’90s when the first studies regarding youth travel were also conducted. No doubt, the concept of youth travel ensues from three notions, namely: youth, tourism and vacation – in the sense of free time. All the definitions used by tourism organizations, by various national tourism administrations an...

  4. Solar wind travel time

    Science.gov (United States)

    Russell, C. T.

    A useful rule of thumb in solar terrestrial studies is that the solar wind travels 4 Earth radii (RE) per minute. Long-term studies of solar wind velocity [e.g., Luhmann et al., 1993; 1994] show that the median velocity is about 420 km/s, corresponding to 3.96 RE min-1. The quartiles are about 370 km/s and 495 km/s, corresponding to 3.48 Re min-1 and 4.66 Re min-1 respectively. This number helps estimate the delays expected when observing a discontinuity at a solar wind monitor; one example is ISEE-3 when it was at the forward libration point (about 60 min). It is also helpful for estimating how much time passes before the dayside magnetosphere is compressed as denser solar wind flows by (about 2.5 min).

  5. The travel-related carbon dioxide emissions of atmospheric researchers

    Directory of Open Access Journals (Sweden)

    A. Stohl

    2008-04-01

    Full Text Available Most atmospheric scientists agree that greenhouse gas emissions have already caused significant changes to the global climate system and that these changes will accelerate in the near future. At the same time, atmospheric scientists who – like other scientists – rely on international collaboration and information exchange travel a lot and, thereby, cause substantial emissions of carbon dioxide (CO2. In this paper, the CO2 emissions of the employees working at an atmospheric research institute (the Norwegian Institute for Air Research, NILU caused by all types of business travel (conference visits, workshops, field campaigns, instrument maintainance, etc. were calculated for the years 2005–2007. It is estimated that more than 90% of the emissions were caused by air travel, 3% by ground travel and 5% by hotel usage. The travel-related annual emissions were between 1.9 and 2.4 t CO2 per employee or between 3.9 and 5.5 t CO2 per scientist. For comparison, the total annual per capita CO2 emissions are 4.5 t worldwide, 1.2 t for India, 3.8 t for China, 5.9 t for Sweden and 19.1 t for Norway. The travel-related CO2 emissions of a NILU scientist, occurring in 24 days of a year on average, exceed the global average annual per capita emission. Norway's per-capita CO2 emissions are among the highest in the world, mostly because of the emissions from the oil industry. If the emissions per NILU scientist derived in this paper are taken as representative for the average Norwegian researcher, travel by Norwegian scientists would nevertheless account for a substantial 0.2% of Norway's total CO2 emissions. Since most of the travel-related emissions are due to air travel, water vapor emissions, ozone production and contrail formation further increase the relative importance of NILU's travel in terms of radiative forcing.

    Full Text Available Transport modes are very important to Libyan’s Tripoli residents for their daily trips. However, the total number of own car and private transport namely taxi and micro buses on the road increases and causes many problems such as traffic congestion, accidents, air and noise pollution. These problems then causes other related phenomena to the travel activities such as delay in trips, stress and frustration to motorists which may affect their productivity and efficiency to both workers and students. Delay may also increase travel cost as well inefficiency in trips making if compare to other public transport users in some Arabs cities. Switching to public transport (PT modes alternatives such as buses, light rail transit and underground train could improve travel time and travel costs. A transport study has been carried out at Tripoli City Authority areas among own car users who live in areas with inadequate of private transport and poor public transportation services. Analyses about relation between factors such as travel time, travel cost, trip purpose and parking cost have been made to answer research questions. Logistic regression technique has been used to analyse these factors that influence users to switch their trips mode to public transport alternatives.

Patrick Holland and Graham Huggan (1998 and Jan Borm (2004, the article presents a characterization of travel writing both as a genre with a precise rhetorical status, as well as a praxis of knoivledge, which derives from the interplay between travelling and writing. Building on this, a comparison between two Italian travel books and two Italian travel blogs about China is proposed. Specifically, by considering these texts as “intermedial transpositions” (Wolf 2008 that realize the same generic and epistemological matrix (i.e. travel writing, a Multimodal Critical Discourse Analysis (MCDA is conducted in order to assess: 1 how the book and the blog, as different medial formats, interpret the rhetorical features of the travel writing genre: and 2 to what extent the gnoseological and cross-cultural potentials of travel writing, as a praxis of knowledge, is affected by the process of transposition.

  17. 2001 New York State NHTS: Travel Patterns of Special Populations

    Energy Technology Data Exchange (ETDEWEB)

    Hu, Patricia S [ORNL; Reuscher, Tim [ORNL

    2010-03-01

    Policymakers rely on transportation statistics, including data on personal travel behavior, to formulate strategic transportation policies, and to improve the safety and efficiency of the U.S. transportation system. Data on personal travel trends are needed to examine the reliability, efficiency, capacity, and flexibility of the Nation's transportation system to meet current demands and accommodate future demands; to assess the feasibility and efficiency of alternative congestion-alleviating technologies (e.g., high-speed rail, magnetically levitated trains, intelligent vehicle and highway systems); to evaluate the merits of alternative transportation investment programs; and to assess the energy-use and air-quality impacts of various policies. To address these data needs, the U.S. Department of Transportation (USDOT) initiated an effort in 1969 to collect detailed data on personal travel. The 1969 survey was the first Nationwide Personal Transportation Survey (NPTS). The survey was conducted again in 1977, 1983, 1990, 1995, and 2001. Data on daily travel were collected in 1969, 1977, 1983, 1990 and 1995. Longer-distance travel was collected in 1977 and 1995. The 2001 National Household Travel Survey (NHTS) collected both daily and longer-distance trips in one survey. The 2001 survey was sponsored by three USDOT agencies: Federal Highway Administration (FHWA), Bureau of Transportation Statistics (BTS), and National Highway Traffic Safety Administration (NHTSA). The primary objective of the survey was to collect trip-based data on the nature and characteristics of personal travel so that the relationships between the characteristics of personal travel and the demographics of the traveler can be established. Commercial and institutional travel was not part of the survey. New York State participated in the 2001 NHTS by procuring additional 12,000 sample households. These additional sample households allowed New York State to address transportation planning issues

    2016-01-01

    Full Text Available Travel stories form part of a great tradition inside Western Culture which has served historically to describe, to understand and to imagine other cul - tures and communities, far or near, being constituted into a real narra - tive genre. This type of story has been and is a reflection of the perception of the world based on the imaginary worlds created by the travelling narrators. How do modern authors of travel stories take advantage of the opportunities offered by transmedia storytelling? The present article explores the potential of these types of stories as a privileged object of study for transmedia storytelling studies, from the analysis of a sample of 80 narrative productions based on experiences of travel and presented in diverse editions of the Festival Le Grand Bivouac (France. It also shows the existence of a new contemporary trend inside this narrative form that transcends its literary nature.

    A popular leisure activity, international travel can be associated with some infections. The most common travel-related illnesses appear to be gastrointestinal, dermatologic, respiratory, and systemic febrile syndromes. The pretravel medical consultation includes immunizations, malaria chemoprophylaxis, self-treatment for traveler's diarrhea, and advice on the prevention of a myriad of other infectious causes including dengue, chikungunya, rickettsiosis, leptospirosis, schistosomiasis, and strongyloidiasis. Travel to locations experiencing outbreaks such as Ebola virus disease, Middle East respiratory syndrome, avian influenza, and chikungunya call for specific alerts on preventive strategies. After travel, evaluation of an ill traveler must explore details of exposure, including destinations visited; activities; ingestion of contaminated food or drinks; contact with vectors, animals, fresh water, or blood and body fluids; and other potential exposures. Knowledge of the geographic distribution of infectious diseases is important in generating the differential diagnoses and testing accordingly. Empiric treatment is sometimes necessary when suspicion of a certain diagnosis is strong and confirmatory tests are delayed or lacking, particularly for infections that are rapidly progressive (for example, malaria) or for which timing of testing is prolonged (such as leptospirosis).

  7. Practical advice for perioperative travel nurses.

    Travel nursing presents unique opportunities that permanent employees may never experience. Today's nursing shortage allows travel nurses to fill temporary staff positions while experiencing the sights, culture, and cuisine of a location of their choosing. This creates a beneficial situation for travel nurses, hospitals, travel companies, and, ultimately, patients. Knowledgeable, flexible nurses and traveler-friendly hospitals can extend contracts if mutually agreeable, thus prolonging the benefits. Before beginning the adventure, however, travelers must have realistic expectations. Many disappointed travelers may have been more successful had they done better research.

    2013-06-01

    The risk of malaria and other communicable diseases is well addressed in pre-travel advice. Accidents are usually less discussed. Thus, we aimed at assessing accident figures for the Swiss population, based on data of the register from 2004 to 2008 of the largest Swiss accident insurance organization (SUVA). More than 139'000 accidents over 5 years showed that 65 % of the accidents overseas are injuries, and 24 % are caused by poisoning or harm by cold, heat or air pressure. Most accidents happened during leisure activities or sports. More than one third of the non-lethal and more than 50 % of the fatal accidents happened in Asia. More than three-quarters of non-lethal accidents take place in people between 25 and 54 years. One out of 74 insured persons has an accident abroad per year. Despite of many analysis short-comings of the data set with regard to overseas travel, the figures document the underestimated burden of disease caused by accidents abroad and should affect the given pre-health advice.

  9. Tympanal travelling waves in migratory locusts.

    Hearing animals, including many vertebrates and insects, have the capacity to analyse the frequency composition of sound. In mammals, frequency analysis relies on the mechanical response of the basilar membrane in the cochlear duct. These vibrations take the form of a slow vibrational wave propagating along the basilar membrane from base to apex. Known as von Békésy's travelling wave, this wave displays amplitude maxima at frequency-specific locations along the basilar membrane, providing a spatial map of the frequency of sound--a tonotopy. In their structure, insect auditory systems may not be as sophisticated at those of mammals, yet some are known to perform sound frequency analysis. In the desert locust, this analysis arises from the mechanical properties of the tympanal membrane. In effect, the spatial decomposition of incident sound into discrete frequency components involves a tympanal travelling wave that funnels mechanical energy to specific tympanal locations, where distinct groups of mechanoreceptor neurones project. Notably, observed tympanal deflections differ from those predicted by drum theory. Although phenomenologically equivalent, von Békésy's and the locust's waves differ in their physical implementation. von Békésy's wave is born from interactions between the anisotropic basilar membrane and the surrounding incompressible fluids, whereas the locust's wave rides on an anisotropic membrane suspended in air. The locust's ear thus combines in one structure the functions of sound reception and frequency decomposition.

  10. The value of travel time variance

    2011-01-01

    This paper considers the value of travel time variability under scheduling preferences that are defined in terms of linearly time varying utility rates associated with being at the origin and at the destination. The main result is a simple expression for the value of travel time variability...... that does not depend on the shape of the travel time distribution. The related measure of travel time variability is the variance of travel time. These conclusions apply equally to travellers who can freely choose departure time and to travellers who use a scheduled service with fixed headway. Depending...... on parameters, travellers may be risk averse or risk seeking and the value of travel time may increase or decrease in the mean travel time....

    With the advancement of urbanization, the original land reserve cannot meet the demand for the spatial expansion. Out⁃skirts of city are transformed into the most important source of land. Land requisition makes plenty of peasants passively come into cities from countryside whose original life style and value meet unprecedented challenge and land⁃losing peasants group emerge. Land urbani⁃zation doesn’ t result in anticipated peasant urbanization, and new dual structure exists in urban society causing lots of problems. By the study on the life style of land⁃losing peasants in the outskirts of Lanzhou, this paper tries to describe their lives transformed by urbani⁃zation, pays attention to their living situation, and further reflects present social policies and leads land⁃losing peasants to reform their life style and integrate into city life.%城市化进程的推进,使得原有的土地储备无法满足高涨的空间扩张需求,“城郊”改造成为了城市建设最重要的土地来源。土地的征收使大量的城郊农民被动地从农村进入城市,其原有的生活方式、价值观念受到了前所未有的冲击与挑战,并由此催生了“失地农民”群体的出现。“土地的城市化”并未必然产生预期的“农民市民化”,新的“二元”结构真实地存在于城市社会之中,并衍生出诸多问题。文章通过对兰州市城郊失地农民生活方式的研究,试图描述出其被城市化改变的人生,关注其生存状况,进而对当前的社会政策进行反思,引导失地农民生活方式的再造,使其真正融入城市生活。

    Mayer, Cora A; Neilson, Amy A

    2010-03-01

    This article is the second in a series providing a summary of prevention strategies and vaccination for infections that may be acquired by travellers. The series aims to provide practical strategies to assist general practitioners in giving travel advice, as a synthesis of multiple information sources which must otherwise be consulted. Poliomyelitis is a potentially fatal viral illness, which may cause acute flaccid paralysis and permanent central nervous system damage. Ongoing global efforts to eradicate poliomyelitis have been under way since 1988. Travellers are at risk of infection in countries with endemic wild poliomyelitis virus or imported cases, and can spread the infection to areas where poliomyelitis has been eradicated. While all adults should be immune to poliomyelitis, it is important that at-risk travellers are vaccinated appropriately. Vaccine options and regions currently reporting poliomyelitis are presented from a number of sources, which may facilitate the process of giving travel advice in a general practice setting, although it is also important to seek up-to-date epidemiological information.

  16. Future Trends in Business Travel Decision Making

    Mason, Keith J.

    2002-01-01

    This research surveys twenty large companies and their travellers to identify and evaluate the effects of pressures on the business travel market in the future. The influence of the following areas on the decision making process are addressed: (1) Corporate travel policies and increasing professionalism in corporate purchasing; (2) The development of global strategic airline alliances; (3) The emergence of low cost airlines on short haul markets; and (4) The development of internet based booking tools and travel agency IT. The survey shows differences in views between travel managers, and travellers with regard to corporate travel policies. While travel managers see policy rules, travellers interpret these as guidelines, indicating travel managers will need to take further actions to exercise true control of travel budgets. The data shows that companies are more likely to prescribe a class of airline ticket, than the choice of airline itself. Corporate hierarchical bias in travel policies is still common both for short and particularly long haul flying. Other findings show that while travel managers believe that their companies are likely to sign global deals with strategic airline groups within a five year period in a bid to consolidating spending, they also believe that nearly a third of short haul flying will be taken with low cost carriers, indicating further penetration in this business travel market by these carriers. The paper also provides other predictions about the business travel market, based on the survey findings.

    Toxoplasma gondii is a protozoan parasite with worldwide distribution that infects more than one third of the global population. Primary infection in immunocompetent individuals is usually asymptomatic; however, different organs can be affected in immunocompromised individuals leading to the development of encephalitis, myocarditis or pneumonitis. The prevalence of infection with Toxoplasma as well as its genetic structure varies geographically and for that reason travel may be considered as a risk factor to acquire the infection. As toxoplasmosis is a foodborne disease, health care providers should give health education on prevention measures to all prospective travelers in order to decrease the risk of infection in endemic areas. This review presents an overview of the infection with T. gondii with some considerations for travelers to and from endemic zones.

  20. Travel epidemiology: the Saudi perspective.

    The Kingdom of Saudi Arabia occupies four-fifths of the Arabian Peninsula, with a land area of 2 million square kilometres. Saudi Arabia holds a unique position in the Islamic world, as the custodian of the two holiest places of Islam, in Mecca and Medina. Annually, some 2 million Muslims from over 140 countries embark on Hajj. This extraordinary en masse migration is a unique forum for the study of travel epidemiology since the Hajj carries various health risks, both communicable and non-communicable, often on a colossal scale. Non-communicable hazards of the Hajj include stampede and motor vehicle trauma, fire-related burn injuries and accidental hand injury during animal slaughter. Communicable hazards in the form of outbreaks of multiple infectious diseases have been reported repeatedly, during and following the Hajj. Meningococcal meningitis, gastroenteritis, hepatitis A, B and C, and various zoonotic diseases comprise some of the possible infectious hazards at the Hajj. Many of these infectious and non-infectious hazards can be avoided or averted by adopting appropriate prophylactic measures. Physicians and health personnel must be aware of these risks to appropriately educate, immunize and prepare these travellers facing the unique epidemiological challenges of Hajj in an effort to minimize untoward effects. Travel epidemiology related to the Hajj is a new and exciting area, which offers valuable insights to the travel specialist. The sheer scale of numbers affords a rare view of migration medicine in action. As data is continually gathered and both national and international policy making is tailored to vital insights gained through travel epidemiology, the Hajj will be continually safeguarded. Practitioners will gain from findings of travel related epidemiological changes in evolution at the Hajj: the impact of vaccinating policies, infection control policies and public health are afforded a real-world laboratory setting at each annual Hajj, allowing us to

    2016-01-01

    The guiding ideology of China�s modernization development strategy is going through the trans⁃formation of“Chinese dream” which is the core of“creating people�s happy life”. In the theoretical system of Marx�s historical materialism, life style is the original concept of the origin of human society and the ontology, which is the ultimate resolution and end result of all social activities. In the real social life, the life style is em⁃bodied in the process of generating and co⁃constructing the social organization as the object of the social organi⁃zation. In order to solve the problem of the marginalization of the life style, we should start with the basic cate⁃gory of“society”, and establish the social concept explanation framework and the new“Life Theory” research paradigm, and break through the limitation of the theory of western sociology, construct the complete “life”category of the “daily life” concept and expand the research of life style.%实现以“创造人民美好生活”为核心的“中国梦”这一战略目标,对生活方式研究提出了迫切的理论需要。在马克思历史唯物主义的理论体系中,生活方式是对人类社会本源、本体加以描述的原发性基础概念,是人类从事一切社会活动最终的落脚点,而现实的生活方式建构体现为作为客体的社会组织同作为社会主体的每个生活者互动生成的文化选择和意义建构过程。生活方式研究是实现社会学中国化的重要组成部分,解决生活方式研究融入社会学理论体系的问题,要从重新界定“社会”基本范畴入手,建立以生活为内核的社会概念解释框架和新的“生活论”研究范式。生活方式研究要突破西方社会学的理论局限,构建超出“日常生活”概念的完整的“生活”范畴,从而扩展生活方式研究的界限,为实现“两个一百年”发展目标提供“创

    Traveling-wave photomixers have superior performance when compared with lumped area photomixers in the 1 to 3 THz frequency range. Their large active area and distributed gain mechanism assure high thermal damage threshold and elimination of the capacitive frequency roll-off. However, the losses experienced by the radio frequency wave traveling along the coplanar strips waveguide (due to underlying semi-infinite GaAs substrate) were a serious drawback. In this paper we present device designs and an experimental setup that make possible the realization of photomixers on membranes which eliminate the losses.

    This study models the impact of the shift from a monocentric private-car-oriented city to polycentric public-transport-oriented city. Metropolitan areas have suffered traffic problems-in particular increase in travel time and travel distance. Urban expansion, population growth and road network development have led to urban sprawl in monocentric cities. In many monocentric cities, travel time and distance has steadily increased and is only expected to increase in the future. Excessive travel leads to several problems such as air pollution, noise, congestion, reduction in productive time, greenhouse emissions, and increased stress and accident rates. This study examines the interaction of land use and travel. A model was developed and calibrated to Melbourne and Riyadh conditions and used for scenario analysis. This model included two parts: a spatial model and a transport model. The scenario analysis included variations of residential and activity distribution, as well as conditions of public transport service.

    2013-01-01

    The purpose of this research is to test the systematic variation in the perception of travel time among travelers and relate the variation to the underlying street network structure. Travel survey data from the Twin Cities metropolitan area (which includes the cities of Minneapolis and St. Paul) is used for the analysis. Travelers are classified into two groups based on the ratio of perceived and estimated commute travel time. The measures of network structure are estimated using the street network along the identified commute route. T-test comparisons are conducted to identify statistically significant differences in estimated network measures between the two traveler groups. The combined effect of these estimated network measures on travel time is then analyzed using regression models. The results from the t-test and regression analyses confirm the influence of the underlying network structure on the perception of travel time.

  7. The trouble with travel and trees

    The aviation industry is a small – although fast-growing – contributor to greenhouse gas emissions, but per kilometre its impact outstrips that of any other form of transport. As today's technology looks unlikely to reduce that impact significantly over the next 25 years, aviation has become a key issue in the climate change debate. Many air travellers and people working in the travel industry see carbon offsetting as a viable green solution to the problem. But how accurate is that view? It is becoming clear that offsetting schemes based on tree planting or forest conservation may trigger a cascade of other problems. Entire communities may be evicted from land allocated for tree planting, or denied access to forest resources designated as protected carbon stores. Forest-based offsetting schemes are also subject to considerable uncertainty: forests can be chopped down or burnt, for instance, which releases stored carbon back into the atmosphere. Some schemes also fail to prevent 'leakage', in which planting trees or conserving forests in one place just shifts deforestation to another, adding nothing to overall carbon stores. For real progress to be made on carbon sequestration and reducing greenhouse gas emissions, we need to go beyond tree-planting and offsetting. Too often they are an excuse for 'business as usual'. The focus must first be on a sustained reduction in emissions. Secondly, it needs to be recognised that the people bearing the heaviest costs of climate change contribute little to the problem, and that new mechanisms for compensating them and helping them adapt to changing conditions are needed. Finally, where offsetting is appropriate, schemes must take full account of the needs and rights of local people who live with the consequences of our new climate consciousness.

    India's tourism industry generated 6.6% of the nation's Gross Domestic Product (GDP) during 2012. International travel to India is predicted to grow at an average annual rate of ∼ 8% over the next decade. The number of foreign tourists has increased by 9% to 5.8 million. Approximately 8% of travelers to developing countries require medical care during or after travel; the main diagnoses are vaccine-preventable diseases. Travelers to India can be exposed to various infectious diseases; water-borne, water-related, and zoonotic diseases may be imported to India where the disease is not endemic. The World Health Organization (WHO) emphasizes that all international travelers should be up to date with routine vaccinations. The recommended vaccinations for travelers to India vary according to the traveler's age, immunization history, existing medical conditions, duration, legal requirements for entry into countries being visited, travelers preferences, and values. Travelers should consult with a doctor so that there is sufficient time for completion of optimal vaccination schedules. No matter where traveling, one should be aware of potential exposure to certain organisms that can cause severely illnesses, even death. There is no doubt that vaccines have reduced or virtually eliminated many diseases that killed or severely disabled children and adults just a few generations ago. Thus, travelers must take recommended vaccines per schedule before traveling to India.

    2016-01-01

    We present the multiply phased current carrying vortex solutions in the U(1) gauge theory coupled to an $(N+1)$-component SU(N+1) scalar multiplet in the Bogomolny limit. Our vortex solutions correspond to the static vortex dressed with traveling waves along the axis of symmetry. What is notable in our vortex solutions is that the frequencies of traveling waves in each component of the scalar field can have different values. The energy of the static vortex is proportional to the topological charge of $CP^N$ model in the BPS limit, and the multiple phase of the vortex supplies additional energy contribution which is proportional to the Noether charge associated to the remaining symmetry.

The new results and techniques of plasma research in fusion plasmas, plasma processing space plasmas, basic plasma science, etc, have broad applicability throughout science. The benefits of these results are limited by the relatively low awareness and appreciation of plasma research in the larger scientific community. Whereas spontaneous interactions between plasma scientists and other scientists are useful, a focused effort in education and outreach to other scientists is efficient and is needed. The academic scientific community is the initial focus of this effort, since that permits access to a broad cross-section of scientists and future scientists including undergraduates, graduate students, faculty, and research staff.

  1. Minimum Covering with Travel Cost

    Fekete, Sandor P; Schmidt, Christiane

    2011-01-01

    Given a polygon and a visibility range, the Myopic Watchman Problem with Discrete Vision (MWPDV) asks for a closed path P and a set of scan points S, such that (i) every point of the polygon is within visibility range of a scan point; and (ii) path length plus weighted sum of scan number along the tour is minimized. Alternatively, the bicriteria problem (ii') aims at minimizing both scan number and tour length. We consider both lawn mowing (in which tour and scan points may leave P) and milling (in which tour, scan points and visibility must stay within P) variants for the MWPDV; even for simple special cases, these problems are NP-hard. We show that this problem is NP-hard, even for the special cases of rectilinear polygons and L_\\infty scan range 1, and negligible small travel cost or negligible travel cost. For rectilinear MWPDV milling in grid polygons we present a 2.5-approximation with unit scan range; this holds for the bicriteria version, thus for any linear combination of travel cost and scan cost.

    Travel is the main multi-particle tracking code being used at CERN for the beam dynamics calculations through hadron and ion linear accelerators. It uses two routines for the calculation of space charge forces, namely, rings of charges and point-to-point. This report presents the studies to improve the performance of Travel using GPU hardware. The studies showed that the performance of Travel with the point-to-point simulations of space-charge effects can be speeded up at least 72 times using current GPU hardware. Simple recompilation of the source code using an Intel compiler can improve performance at least 4 times without GPU support. The limited memory of the GPU is the bottleneck. Two algorithms were investigated on this point: repeated computation and tiling. The repeating computation algorithm is simpler and is the currently recommended solution. The tiling algorithm was more complicated and degraded performance. Both build and test instructions for the parallelized version of the software are inclu...

    Travel medicine practitioners, perhaps more so than medical practitioners working in other areas of medicine, require a constant flow of information to stay up-to-date, and provide best practice information and care to their patients. Many travel medicine providers are unaware of the popularity and potential of the Twitter platform. Twitter use among our travellers, as well as by physicians and health providers, is growing exponentially. There is a rapidly expanding body of published literature on this information tool. This review provides a brief overview of the ways Twitter is being used by health practitioners, the advantages that are peculiar to Twitter as a platform of social media, and how the interested practitioner can get started. Some key points about the dark side of Twitter are highlighted, as well as the potential benefits of using Twitter as a way to disseminate accurate medical information to the public. This article will help readers develop an increased understanding of Twitter as a tool for extracting useful facts and insights from the ever increasing volume of health information.

Important risks including accidents and cardiovascular events are not routinely included in pre-travel consultations although they cause more fatalities and costs than infectious diseases. The increased risk of sustaining a road accident in poor economy countries should always be mentioned. The general practitioner is further best placed to discuss possible problems of travellers with chronic diseases before travel.

    Illness in business travelers is associated with reduced productivity on the part of the employee as well as the employer. Immunizations offer a reliable method of preventing infectious diseases for international business travelers. The authors review the travel patterns of business travelers, available data on illnesses they encounter, their potential travel-associated risks for vaccine-preventable diseases and recommendations on immunizations for this population. Routine vaccines (e.g., measles, tetanus and influenza) should be reviewed to assure that they provide current coverage. The combined hepatitis A and hepatitis B vaccine with a rapid schedule offers options for those with time constraints. Other vaccine recommendations for business travelers need to focus on their destinations and activities and underlying health, taking into account the concept of cumulative risk for those with frequent travel, multiple trips or long stays.

    2001-06-01

    Many HIV-infected persons travel from temperate zones to (sub)tropical destinations. HIV-specific immigration issues, medical resources abroad and problems regarding travelling with multiple medications have to be anticipated. When prescribing immunizations and specific chemoprophylaxis, the stage of immunodeficiency as well as drug interactions with antiretrovirals and medicaments against opportunistic infections have to be taken into account. Live vaccines may be contraindicated. Immunocompromised HIV-infected travellers have a higher risk for serious courses of diseases by enteropathogens. Therefore a good information about food hygiene is important and a prescription of an antibiotic to take in case of severe diarrhea may be indicated. A new antiretroviral combination therapy should not be started immediately before travelling to the tropics. The possibility to continue an established HIV treatment during travel has to be evaluated cautiously. With good pre-travel advice the risk of severe health problems is low for most HIV-infected travellers.

    Torres-Ruiz, J; Sulli, A; Cutolo, M; Shoenfeld, Y

    2017-02-27

    Biological rhythms are fundamental for homeostasis and have recently been involved in the regulatory processes of various organs and systems. Circadian cycle proteins and hormones have a direct effect on the inflammatory response and have shown pro- or anti-inflammatory effects in animal models of autoimmune diseases. The cells of the immune system have their own circadian rhythm, and the light-dark cycle directly influences the inflammatory response. On the other hand, patients with autoimmune diseases characteristically have sleep disorders and fatigue, and in certain disease, such as rheumatoid arthritis (RA), a frank periodicity in the signs and symptoms is recognized. The joint symptoms predominate in the morning, and apparently, subjects with RA have relative adrenal insufficiency, with a cortisol peak unable to control the late night load of pro-inflammatory cytokines. Transatlantic flights represent a challenge in the adjustment of biological rhythms, since they imply sleep deprivation, time zone changes, and potential difficulties for drug administration. In patients with autoimmune diseases, the use of DMARDs and prednisone at night is probably best suited to lessen morning symptoms. It is also essential to sleep during the trip to improve adaptation to the new time zone and to avoid, as far as possible, works involving flexible or nocturnal shifts. The study of proteins and hormones related to biological rhythms will demonstrate new pathophysiological pathways of autoimmune diseases, which will emphasize the use of general measures for sleep respect and methods for drug administration at key daily times to optimize their anti-inflammatory and immune modulatory effects.

  19. Compensation of CO2 emissions by air travels: an example

    Directory of Open Access Journals (Sweden)

    Lombardi F

    2011-05-01

    Full Text Available In recent years, several aircraft companies launched awareness campaigns, offering to their passenger the opportunity to known and also calculate their own per-capita CO2 emissions related to the flight they are going to make. Such campaigns permits to the passenger to pay a volunteer contribution in order to compensate their CO2 emissions. In this short communication, some programs undertaken by airline companies are showed. These initiatives are all characterized by a common denominator: the achievement of concrete, proved and verifiable results to compensate the aircraft CO2 emissions. Moreover, also a concrete case is reported as example: it is useful to show which is the per capita CO2 emission for a sample flight in Europe and, quantitatively, the amount of compensation measurements. Finally, this communication highlights on how the estimates of such measurements are usually miscalculated, considering that the capability of forest ecosystems to store CO2 are often underestimated.

    Full Text Available The Aviation Administration policy prohibits the use of mobile phones in Aircraft during transition for the reason it may harm their communication system due to Electromagnetic interference. In case the user wants to access cellular network at higher altitudes, base station access is a problem. Large number of channels are allocated to a single user moving at high speed by various Base Stations in the vicinity to service the request requiring more resources. Low Altitude Platforms (LAPs are provided in the form of Base stations in the Airships with antennas projected upwards which has direct link with the Ground Station. LAPs using LongEndurance Multi-Intelligence Vehicle (LEMVs equipped with an engine for mobility and stable positioning against rough winds are utilized. This paper proposes a system that allows the passengers to use their mobiles in Aircraft using LAPs as an intermediate system between Aircraft and Ground station. As the Aircraft is dynamic, it has to change its link frequently with the Airships, MANETs using AODV protocol is established in the prototype using NS2 to provide the service and the results are encouraging

    Full Text Available We analyze rigorously the one-dimensional traveling wave problem for a thermodynamically consistent phase field model. Existence is proved for two new cases: one where the undercooling is large but not in the hypercooled regime, and the other for waves which leave behind an unstable state. The qualitative structure of the wave is studied, and under certain restrictions monotonicity of front profiles can be obtained. Further results, such as a bound on propagation velocity and non-existence are discussed. Finally, some numerical examples of monotone and non-monotone waves are provided.

  7. [Infectious aetiologies of travelers' diarrhoea].

    2007-11-01

    Traveler's diarrhoea (TD) occurs in 20 to 60% of European or North-American travelers in intertropical areas. Following return from endemic zone, malaria must always be evocated in front of febrile diarrhoea. Many causative infectious agents are involved in TD and their frequency may vary according to destination and seasons. The main agents involved in TD are Escherichia coli pathovars (especially enterotoxigenic and enteroaggregative E. coli) followed by enteroinvasive bacteria (Campylobacter spp., Shigella spp., Salmonella enterica), enteric viruses (norovirus, rotavirus) and protozoa (Gardia intestinalis, Cryptosporidium parvum et Entamoeba histolytica). The development of molecular biology methods as PCR may allow us to evaluate the relative frequency of these agents and especially of viral agents in TD. Protozoa and microsporidia are more frequently isolated in persistent and chronic TD, especially in compromised patients. A complete etiological research in routine microbiology laboratories is difficult and time-consuming, related to the high diversity of causative agents and the need for specific methods. Implementation of laboratory diagnosis is highly recommended when diarrhoea is associated with fever or presence of blood in stools, immunosuppression, antibiotic treatment (Clostridium difficile toxins) or in case of persistent/chronic diarrhoea. According to the high frequency of acquired antibiotic-resistance in enteric bacteria, an antibiogram must be performed for all causative bacterial agents.

  8. Is Interstellar Space Travel Possible?

    2013-01-01

    It is shown that space travel, even in the most distant future, will remain confined to our own planetary system, and a similar conclusion will hold forth for any other civilization, no matter how advanced it might be, unless those extra-terrestrial species have life spans order of magnitude longer than ours. Even in such a case it is unlikely that they will travel much farther than their immediate stellar neighbourhood, as each such excursion will exhaust the resources of their home planet so much that those will dwindle rather fast and there might not be much left for the further scientific and technological advancements. So the science-fiction fancy of a "Galactic Empire" may ever remain in our fantasies only. And as for the mythical UFOs, whose quiet appearances do get reported in the press once in a while, recent explorations have shown no evidence that any such thing could have an origination within our own solar system itself. And a "quiet trip" back and forth from a distant star is almost impossible a...

    The number of international travellers has increased. There is enormous diversity in medical backgrounds, purposes of travel, and travelling styles among travellers. Travellers are hospitalized abroad because of exotic and common diseases via medical tourism. This is one way of transporting and importing human bacteria between countries, including multi-drug resistant organisms. In developing countries, the antimicrobial resistance in Shigella sp. and Salmonella sp. have been a problem, because of this trend, the first choice of antibiotics has changed in some countries. Community acquired infections as well as hospital acquired infections with MRSA, multi-drug resistance (MDR) Pseudomonas aeruginosa, and ESBL have been a problem. This review will discuss the risk of MDR bacterial infectious diseases for travellers.

    2016-10-01

    The propagation of traveling Lamb wave in single layer of elastic metamaterial is investigated in this paper. We first categorized the traveling Lamb wave modes inside an elastic metamaterial layer according to different combinations (positive or negative) of effective medium parameters. Then the impacts of the frequency dependence of effective parameters on dispersion characteristics of traveling Lamb wave were studied. Distinct differences could be observed when comparing the traveling Lamb wave along an elastic metamaterial layer with one inside the traditional elastic layer. We further examined in detail the traveling Lamb wave mode supported in elastic metamaterial layer, when the effective P and S wave velocities were simultaneously imaginary. It was found that the effective modulus ratio is the key factor for the existence of special traveling wave mode, and the main results were verified by FEM simulations from two levels: the level of effective medium and the level of microstructure unit cell.

    Children are traveling to regions of the world that could pose a risk of acquiring diseases such as malaria, dermatosis, and infectious diarrhea. Most of these can be prevented by modifying high-risk behaviors or through the use of medications. Many of these same regions are endemic with diseases that are preventable through vaccination. Clinicians must be able to effectively prepare their pediatric-age travelers for international travel. Preventive education, prophylactic and self-treating medications, and vaccinations are all important components of this preparation. Familiarity with the use of travel vaccines is imperative.

    2016-05-01

    Malaria is declining in many tropical countries. This reduction challenges our usual preventive strategies. In moderate to low risk areas, the Swiss guidelines recommend a stand-by emergency treatment. Controversies between experts are numerous though. Professionals at the Travel Clinic in Lausanne has explored shared-decision making through three clinical studies. The first showed that travelers visiting moderate to low risk malaria areas prefer a standby emergency treatment rather than chemoprophylaxis. The second study investigates the use of rapid diagnostic tests by travelers. The third focuses on the prospects of tropical telemedicine. Involving the traveler into the debate is a priority, until a vaccine becomes available.

    This paper provides a detailed empirical investigation of the distribution of travel times on an urban road for valuation of travel time variability. Our investigation is premised on the use of a theoretical model with a number of desirable properties. The definition of the value of travel time...... variability depends on certain properties of the distribution of random travel times that require empirical verification. Applying a range of nonparametric statistical techniques to data giving minute-by-minute travel times for a congested urban road over a period of five months, we show that the standardized...... travel time is roughly independent of the time of day as required by the theory. Except for the extreme right tail, a stable distribution seems to fit the data well. The travel time distributions on consecutive links seem to share a common stability parameter such that the travel time distribution...

  18. Headache associated with airplane travel: A rare entity

    Directory of Open Access Journals (Sweden)

    Ajith Cherian

    2013-01-01

    Full Text Available Airplane travel headache is rare and has recently been described as a new form of headache associated with a specific situation. Of the 1,208 patients with primary headaches attending a tertiary care neurology hospital, two (0.16% patients satisfied the criteria for headache related to airplane travel. Both the patients fulfilled the proposed diagnostic criteria for airplane travel headache. This unique headache had a mean duration of 24 minutes, localized to the medial supraorbital region described as having an intense jabbing or stabbing character that occurred exclusively and maximally during aircraft landing or take-off, following which pain intensity subsided . This rare headache felt on aircraft descent is probably due to the squeeze effect on the frontal sinus wall, when air trapped inside it contracts producing a negative pressure leading to mucosal edema, transudation and intense pain. Use of nasal decongestants either alone or in combination with naproxen sodium prior to ascent and descent abated the headache episodes. Awareness about this unique entity is essential to provide proper treatment and avoid patient suffering.

    1997-01-01

    This note is about introducing classical mechanics in a way that overtly dispels Newtonian misconceptions, minimizing the obstacles to a student's eventual understanding of space-time. This is done by operationally defining all quantities that depend on the observer's state of motion, including time, with respect to a specific ``map-frame'', and by introducing the classical equations for energy, momentum, and velocity-addition as low-speed approximations. It also provides tools for quantifying unidirectional motion at any speed, by students freshly-introduced to constant acceleration. This is done by describing traveler-time as the invariant in the metric equation, presented as a space-time extension of Pythagoras' theorem. Confusions involving frame-dependent simultaneity and length-contraction are minimized by considering only distances measured by observers in the reference map-frame.

  1. Traveling waves of selective sweeps

    CERN Document Server

    Durrett, Rick

    2009-01-01

    The goal of cancer genome sequencing projects is to determine the genetic alterations that cause common cancers. Many malignancies arise during the clonal expansion of a benign tumor which motivates the study of recurrent selective sweeps in an exponentially growing population. To better understand this process, Beerenwinkel et al.(2007) consider a Wright-Fisher model in which cells from an exponentially growing population accumulate advantageous mutations. Simulations show a traveling wave in which the time of the first k-fold mutant, $\\tau_k$, is approximately linear in $k$ and heuristics are used to obtain formulas for $E\\tau_k$. Here, we consider the analogous problem for the Moran model and prove that as the mutation rate $\\mu\\to 0$, $\\tau_k \\sim c_k \\log(1/\\mu)$, where the $c_k$ can be computed explicitly.

  2. Enslaved Constitution: Obstructing the Freedom to Travel

    Directory of Open Access Journals (Sweden)

    Mitchell F. Crusto

    2008-04-01

    Full Text Available Does the Constitution protect a citizen’s intra-state travel (within a state from unjustified state prohibition? To date, the Supreme Court has not ruled directly on the issue, and many federal courts believe that the right to intrastate travel is not constitutionally protected. This Article explores the constitutional right of intra-state travel that is free from wrongful state infringement along public roadways by law-abiding citizens. Using critical legal history, this Article poses that federal courts’ denial of the right to intrastate travel consciously or unconsciously reflects the antebellum, Southern legal doctrine of people as property, which regulated the travel of enslaved African descendants.The constitutionality of intra-state travel arose most recently during the Hurricane Katrina Crisis when the City of Greta, Louisiana police barricaded a federal highway, denying would-be evacuees the ability to flee from the flooding City of New Orleans. In an ensuing action for infringement of the would-be evacuees’ constitutional right to intra-state travel, Federal District Judge Mary Ann Vial Lemmon dismissed the matter in Dickerson v. City of Gretna, holding that “[w]hile there is no doubt that a fundamental right of interstate travel exists, the Supreme Court has not ruled on whether a right of intra[-]state travel exists. This Court declines to find that there is a fundamental right to intra[-]state travel.” The Fifth Circuit affirmed the ruling.This Article recommends that when federal courts assess whether there is a constitutional right to intra-state travel, they should embrace the American paradigm of liberty and abandon the antebellum, Southern paradigm of enslavement. Consistent with Professor Derrick Bell’s “interestconvergence” principle, all Americans benefit when the Constitution protects the human rights of the least powerful American.

    The fields of travel and international medicine are rapidly changing and growing. The role of occupational and travel health nurses is expanding and should be a focus for the future. At the American Association of Occupational Health Nurses Annual meeting on March 24, 2015, in Boston, five presentations were included in the session, An Update on Travel Vaccines and Issues in Travel and International Medicine. This article summarizes three of the presentations and includes a portion of the information generated by the Centers for Disease Control and Prevention (CDC) included in the fourth presentation. The first section focuses on the Essential Elements of Travel Medicine Programs including the pre-travel care assessment, trip research and risk identification, medication intervention review, non-pharmaceutical and prevention strategies, and post-travel care. The next section is an overview of key issues for business travelers. The growth in the number of international business travelers and unique aspects of business travel are emphasized in a comprehensive travel health program. This section also includes a discussion of expatriates and their special risks identified in recent literature (e.g., an assessment of the significant costs of health events and productivity losses by both business travelers and expatriates). The final section offers a specific example of a vaccine-preventable disease, namely, Japanese encephalitis (JE) virus, and needed changes in JE vaccine recommendations.

  10. Tropical diarrhoea: new developments in traveller's diarrhoea.

    2001-10-01

    Traveller's diarrhoea is the most common illness acquired by visitors to developing countries, affecting 20-50% of the 35 million people who travel from industrialized countries each year. Important risk factors include point of origin and destination of the traveller, host factors, and exposure to contaminated food and water. The most common causes of traveller's diarrhoea in adults in developing countries include infection with Escherichia coli, Shigella spp., Salmonella spp., Campylobacter spp., Vibrio parahaemolyticus (in Asia), rotavirus (in Latin America), and protozoa (Giardia, Cryptosporidium and Cyclospora spp., and Entamoeba histolytica). No pathogen is identified in over half of patients with traveller's diarrhoea, however. The primary objectives of treatment of traveller's diarrhoea are to reduce the symptoms and duration of diarrhoeal illness, to reduce inconvenience caused by such illness and to prevent cancellation of planned activities. These important objectives are best accomplished by empirical self-therapy with a combination of antimicrobial agents and loperamide. Since the first use of ciprofloxacin, fluoroquinolones have become the drugs of choice in empirical therapy for moderate-to-severe traveller's diarrhoea in adults. The options for children include nalidixic acid, trimethoprim-sulfamethoxazole (along with erythromycin if Campylobacter infection is a possibility) and furazolidone. Education on hygiene and safe food preparation help to prevent many diarrhoeal diseases, including traveller's diarrhoea.

    We derive parametric travelling-wave solutions of non-linear QCD equations. They describe the evolution towards saturation in the geometric scaling region. The method, based on an expansion in the inverse of the wave velocity, leads to a solvable hierarchy of differential equations. A universal parametric form of travelling waves emerges from the first two orders of the expansion.

    International travel is a frequent occurrence in the life of the elite athlete; such travel can pose challenges to the sport medicine practitioner. Travel is also the reality of many recreational level or sub-elite athletes as opportunities for international competition and training proliferate. An appreciation of the range of responsibilities associated with the preparation for and the strategies to facilitate such travel is essential for any physician charged with the care of athletes and teams. An appreciation of (1) the medical and public health challenges associated with competition in a particular setting; (2) the requirements for vaccination and immunization; (3) the strategies for the management of jet lag and climatic or environmental extremes; (4) the range of supplies and equipment necessary for travel to certain locales; (5) the need to ensure the availability of ample familiar and nutritious foods; (6) the potential need for specialty care in strange settings; (7) the management of common travel-associated illness; and (8) the challenges associated with the evacuation of an injured athlete are fundamental to the successful management of international travel involving athletes and teams. The adoption of a methodical approach to pre-trip planning can ensure an enhanced travel experience, illness-free training and competition, and facilitate optimal performance.

  18. Cybermediation in the Tourism and Travel Industries

    Science.gov (United States)

    Killion, Les

    Travel and tourism are second only to pornography in adopting Internet-based technologies to intermediate between those supplying the total travel experience, and those seeking to satisfy leisure needs by engaging in tourism. From Thomas Cook in the 1800s, traditional ‘travel trade networks’ have provided the components of the travel experience: transport, accommodation and attractions. However, the Internet has encouraged customer self-service, and on-going debate regarding the future of traditional travel trade intermediaries. The intermediation debate suggests the emergence of ‘hybrid’ intermediation systems combining customer self-service with face-to-face customer contacts characteristic of traditional travel agents. A focus group investigation identified profiles and motives of customers using the Internet to make holiday arrangements. Potential cost savings are a primary motivation for customer self-service. Using the Internet for travel and tourism is becoming commonplace among older travellers as well as younger people. In gathering information before making holiday decisions, potential tourists also engage in a Web 2.0 environment where family and friends, not established intermediaries, provide reliable and authentic information via their individual blogs.

  2. Limitations of typhoid vaccination for travellers.

    Science.gov (United States)

    Stephen, J; Mara, N; Nathwani, D

    1996-12-01

    Around one-third of travellers to endemic areas receive pre-travel typhoid vaccination, increasingly with the new parenteral vaccination Typhim Vi (Mérieux). More than 200 cases of Salmonella typhi and S. paratyphi infection are imported into the UK each year. Despite the widespread use of immunisation, non-specialist clinicians and the travelling public do not appear to fully appreciate the limitations of currently available vaccination. These limitations are not adequately highlighted in either the Green Book of Immunisation against Infectious Diseases (HMSO, 1992) or the new handbook Health Information for Overseas Travel (HMSO, 1995) which are important sources of reference for clinicians and practice nurses. This may delay consideration of diagnosis and presentation for treatment in immunised travellers.

    Peate, W F; Pust, R E

    1985-03-01

    After Canada, Mexico is the most popular destination for Americans traveling outside the United States. As a developing country, Mexico presents numerous health hazards to American visitors, including the prevalent travelers' diarrhea (turista), from which 40% will suffer, and the less common typhoid, dengue, rabies, malaria, taeniasis, cysticercosis, and trichinosis. Environmental hazards, including sun, heat, high altitude, motion sickness, and accidents, also threaten the unwary traveler. In the event of illness or injury, Americans may find medical facilities unfamiliar and less well equipped than those in the United States. Utilizing both an individualized risk assessment for each traveler and readily available references, physicians, in partnership with local public health agencies, can develop comprehensive preventive health plans for their patients traveling to Mexico.

    Whether dodging bullets in West Africa, or rabid dogs in Pakistan, surviving yak-butter tea in Tibet, or eating raw fish in China, the life of a globe-trotting fossil hunter is often hazardous and always filled with surprises. Travels with the Fossil Hunters lets readers share the wonder, joys of discovery, and excitement of these intrepid scientists. Packed with more than 100 beautiful, full-color photographs, the volume takes readers on twelve expeditions to remote parts of the world in search of diverse fossil remains, from those of dinosaurs to human ancestors. Each expedition by paleontologists from London's Natural History Museum reveals the problems and challenges of working in extreme conditions, from the deserts of the Sahara and Yemen to the frozen wastes of Antarctica, from the mountains of India to the forests of Latvia. Along the way they also describe the paleontology and geology of the countries they visit and the scientific reasons for their expeditions. With a foreword from Sir David Attenborough and an introduction from Richard Fortey, this fascinating book will appeal to amateur and professional fossil hunters alike and to readers interested in accounts of exotic locales. Peter Whybrow is a research scientist at the Natural History Museum, London. His research interests include Arabian Miocene vertebrates, paleoclimates, paleogeography, and biotic diversity. He is senior editor with A. Hill of Fossil Vertebrates of Arabia (Yale University Press, New Haven, 1999).

  7. The General Traveling Salesman Problem

    2011-01-01

    This is concerned with essentially two ways in which to construct algorithms for obtaining both approximate and exact solutions to the general traveling salesman problem (GTSP)(the triangle equality need not be satisfied). The first uses an arbitrary n-cycle to permute the columns of an n X n matrix with weighted entries. In doing so, we obtain negative entries. Using these entries, we from negative cycles. We give a formula for the length of cycles necessary to obtain an n-cycle by patching. Using patching of negative cycles, we obtain an n-cycle. The second portion of the algorithm gives procedures for obtain an exact solution to the GTSP. Our second algorithm uses the average arc-value (aav) of a path. We first obtain an n-cycle in a manner similar to that in the first algorithm. Call this T_UPPERBOUND. We then construct paths each of which has an aav less than that of T_UPPERBOUND. Using parallel programming, we construct all paths whose values are less than that of T_UPPERBOUND. Then either we obtain an ...

    Leptospirosis remains the most widespread zoonotic disease in the world, commonly found in tropical or temperate climates. While previous studies have offered insight into intra-national and intra-regional transmission, few have analyzed transmission across international borders. Our review aimed at examining the impact of human travel and migration on the re-emergence of Leptospirosis. Results suggest that alongside regional environmental and occupational exposure, international travel now constitute a major independent risk factor for disease acquisition. Contribution of travel associated leptospirosis to total caseload is as high as 41.7% in some countries. In countries where longitudinal data is available, a clear increase of proportion of travel-associated leptospirosis over the time is noted. Reporting patterns is clearly showing a gross underestimation of this disease due to lack of diagnostic facilities. The rise in global travel and eco-tourism has led to dramatic changes in the epidemiology of Leptospirosis. We explore the obstacles to prevention, screening and diagnosis of Leptopirosis in health systems of endemic countries and of the returning migrant or traveler. We highlight the need for developing guidelines and preventive strategies of Leptospirosis related to travel and migration, including enhancing awareness of the disease among health professionals in high-income countries.

  10. Multimodal Network Equilibrium with Stochastic Travel Times

    Directory of Open Access Journals (Sweden)

    M. Meng

    2014-01-01

    Full Text Available The private car, unlike public traffic modes (e.g., subway, trolley running along dedicated track-ways, is invariably subject to various uncertainties resulting in travel time variation. A multimodal network equilibrium model is formulated that explicitly considers stochastic link capacity variability in the road network. The travel time of combined-mode trips is accumulated based on the concept of the mean excess travel time (METT which is a summation of estimated buffer time and tardy time. The problem is characterized by an equivalent VI (variational inequality formulation where the mode choice is expressed in a hierarchical logit structure. Specifically, the supernetwork theory and expansion technique are used herein to represent the multimodal transportation network, which completely represents the combined-mode trips as constituting multiple modes within a trip. The method of successive weighted average is adopted for problem solutions. The model and solution method are further applied to study the trip distribution and METT variations caused by the different levels of the road conditions. Results of numerical examples show that travelers prefer to choose the combined travel mode as road capacity decreases. Travelers with different attitudes towards risk are shown to exhibit significant differences when making travel choice decisions.

Accordingly, the media market is a process of qualitative and quantitative changes. There is a growing number of distribution channels, many of which are convergent evolution. The transformation of the old forms is determined by market demand. These processes are inevitably reflected in the dominance of certain functions of the travelogue. However, their essential purpose remains the same: to inform, educate and entertain.

    The travel times of acoustic rays traced through a climatological sound-speed profile are compared with travel times computed through the same profile containing an eddy field. The accuracy of linearizing the relations between the travel time difference and the sound-speed deviation at long ranges is assessed using calculations made for two different eddy fields measured in the eastern Atlantic. Significant nonlinearities are found in some cases, and the relationships of the values of these nonlinearities to the range between source and receiver, to the anomaly size associated with the eddies, and to the positions of the eddies are studied. An analytical model of the nonlinearities is discussed.

    Full Text Available In the course of the nineteenth century Arminius Vambery, an anglophile travel writer, in the guise of a mendicant dervish with a group of Tartar pilgrims departs to secluded and sealed Central Asia. After six months travel in the Khanates of Central Asia, he undertakes a journey to England where he offers his observations to the Royal Geographical Society and publishes his travelogue, Travel in Central Asia. Despite its literary merits and connection with British imperialism, the travelogue has not been scrutinized separately by the scholars of travel writing. To fill the gap, this article by drawing on the theories of post-structuralism: Orientalism and Postcolonialism, endeavors to unveil the political agenda behind the travel writer’s representation of his travelees, destination, and his own traveling self. Additionally, it argues that the travel writer in dialogue with other Western travel writers to deterritorialize his traversed region or justify the prospective presence of Britain in Central Asia, represents his journey destination as the locus of barbarity, a region under the grip of despotic rulers, as well as an area with frozen time, while to exhibit his Eurocentrism, he portrays his traveling subject as the a suffering hero and a benign traveler.

    Full Text Available BACKGROUND: Recent studies have indicated an increased risk of venous thrombosis after air travel. Nevertheless, questions on the magnitude of risk, the underlying mechanism, and modifying factors remain unanswered. METHODS AND FINDINGS: We studied the effect of various modes and duration of travel on the risk of venous thrombosis in a large ongoing case-control study on risk factors for venous thrombosis in an unselected population (MEGA study. We also assessed the combined effect of travel and prothrombotic mutations, body mass index, height, and oral contraceptive use. Since March 1999, consecutive patients younger than 70 y with a first venous thrombosis have been invited to participate in the study, with their partners serving as matched control individuals. Information has been collected on acquired and genetic risk factors for venous thrombosis. Of 1,906 patients, 233 had traveled for more than 4 h in the 8 wk preceding the event. Traveling in general was found to increase the risk of venous thrombosis 2-fold (odds ratio [OR] 2.1; 95% confidence interval [CI] 1.5-3.0. The risk of flying was similar to the risks of traveling by car, bus, or train. The risk was highest in the first week after traveling. Travel by car, bus, or train led to a high relative risk of thrombosis in individuals with factor V Leiden (OR 8.1; 95% CI 2.7-24.7, in those who had a body mass index of more than 30 kg/m(2 (OR 9.9; 95% CI 3.6-27.6, in those who were more than 1.90 m tall (OR 4.7; 95% CI 1.4-15.4, and in those who used oral contraceptives (estimated OR > 20. For air travel these synergistic findings were more apparent, while people shorter than 1.60 m had an increased risk of thrombosis after air travel (OR 4.9; 95% CI 0.9-25.6 as well. CONCLUSIONS: The risk of venous thrombosis after travel is moderately increased for all modes of travel. Subgroups exist in which the risk is highly increased.

    Health safety during trips is based on previous counseling, vaccination and prevention of infections, previous diseases or specific problems related to the destination. Our aim was to assess two aspects, incidence of health problems related to travel and the traveler's awareness of health safety. To this end we phone-interviewed faculty members of a large public University, randomly selected from humanities, engineering and health schools. Out of 520 attempts, we were able to contact 67 (12.9%) and 46 (68.6%) agreed to participate in the study.

Most trips lasted usually one week or less. Duration of the travel was related to the destination, with (12h) or longer trips being taken by 68.2% (30/44) of travelers, and the others taking shorter (3h) domestic trips. Most travelling was made by air (41/44) and only 31.8% (14/44) of the trips were motivated by leisure. Field research trips were not reported. Specific health counseling previous to travel was reported only by two (4.5%).

    Soriguera Martí, Francesc

    2016-01-01

    This monograph presents a simple, innovative approach for the measurement and short-term prediction of highway travel times based on the fusion of inductive loop detector and toll ticket data. The methodology is generic and not technologically captive, allowing it to be easily generalized for other equivalent types of data. The book shows how Bayesian analysis can be used to obtain fused estimates that are more reliable than the original inputs, overcoming some of the drawbacks of travel-time estimations based on unique data sources. The developed methodology adds value and obtains the maximum (in terms of travel time estimation) from the available data, without recurrent and costly requirements for additional data. The application of the algorithms to empirical testing in the AP-7 toll highway in Barcelona proves that it is possible to develop an accurate real-time, travel-time information system on closed-toll highways with the existing surveillance equipment, suggesting that highway operators might provide...

    Typhoid vaccination is recommended in the United States before travel to countries where typhoid fever is endemic, though little information is available on its effectiveness in travelers. We estimated typhoid vaccination effectiveness (VE) by comparing vaccination status in cases of typhoid fever and paratyphoid fever (Salmonella Paratyphi A infection, against which typhoid vaccine offers no protection) reported in the United States. We included travelers to Southern Asia and excluded persons vaccination status was not reported. From 2008 through 2011, 744 eligible cases (602 typhoid, 142 paratyphoid A) were reported to CDC. Typhoid vaccination was reported for 5% (29/602) of typhoid patients and for 20% (29/142) of paratyphoid A patients. Estimated VE was 80% (95% confidence interval, 66-89%). Because of missing data, we could not estimate VE for specific vaccines. We demonstrated moderate effectiveness of typhoid vaccination in US travelers, supporting vaccination recommendations.

    We study the so-called traveling tournament problem (TTP) to find an optimal tournament schedule. Differently from the original TTP, in which the total travel distance of all the participants is the objective function to minimize, we instead seek to maximize the fairness of the round robin tournament schedule of the Korean Baseball League. The standard deviation of the travel distances of teams is defined as the energy function, and the Metropolis Monte-Carlo method combined with the simulated annealing technique is applied to find the ground-state configuration. The resulting tournament schedule is found to satisfy all the constraint rules set by the Korean Baseball Organization, but with drastically increased fairness in traveling distances.

    Travel Medicine has come a long way since it was started in the 1980s. Today, with the advances in electronic communications and efficient international travel, the demand for up-to-date information on international health situation is more urgent than before. Disease outbreaks can be updated and be available immediately across to the whole world in a matter of hours via the Internet. Travel medicine specialists no longer can give the excuse that they are unaware of such a situation because it is posted all over the net. Advances in vaccine development and the work of international agencies like the World Health Organization and the Centres for Disease Control have helped further the strategies and the knowledge we have in travel health risks. For the traveller, this means that they should no longer be travelling to a destination without knowing the health hazards and without taking the appropriate prophylaxis and precautions.

    Advanced civilizations capable of interstellar travel, if they exist, are likely to have advanced propulsion methods. Spaceships moving at high speeds would leave a particular signature which could be detected from Earth. We propose a search based on the properties of light reflecting from objects travelling at relativistic speeds. Based on the same principles, we also propose a simple interstellar beacon with a solar sail.

    Traveler's diarrhea is a very common condition that affects approximately 12 million subjects each year. This disorder is benign but nevertheless interferes with the traveler's plans in 40% of cases. Several drugs have been used for prophylaxis, in association with appropriate precautions concerning food and drink. Trimethoprim-sulfamethoxazole and cyclines are effective but may induce adverse effects. Nifuroxazide in a dose of 400 mg each day throughout the trip has proved effective. Tolerance was outstanding with no adverse effects.
