Impact of quality and environmental investment on business competitiveness and profitability: The case of travel agencies

Few studies have examined the combined effect of implementing quality and environmental management within the service sector. This void is more evident if we focus on segments in which small businesses predominate and even more so if we look for highly competitive sectors that are very variable and that have high business mortality. After analysing 198 surveys of Spanish travel agency managers using structural equations, it can be concluded that practices of quality management have a significant direct impact on business competitiveness but not on this business's financial results, at least directly. However, there is a significant relationship between environmental management practices and economic benefits. This article suggests that commitment to quality and the environment can allow small businesses in the service sector to have a competitive advantage that will separate surviving and ceased operations, particularly in sectors that are rapidly evolving and highly competitive.

“Illegal Aliens” and the Inconspicuous Geographies of US Immigration and Border Policing within 100 Miles of the US-Canada Border

Legal provisions in the US have extended the idea of the border to the inside of US territory. Border Patrol Agents confront people in different spaces to inquire about their status. I examine border policing along the northern border of the United States through textual and discourse analysis. This thesis asks: How do border agents exercise power and control the movement of people within 100 miles of the border? In whose interest is the border, the “nation,” secured? The spaces in which these mobile borders are practiced become the sites where “citizens” and “aliens” are produced, reproduced and contested. These border policing practices create the illusion of a “nation” that is secured for “our” interests. However, the interests of these vulnerable groups are not reflected in the immigration policy and along the “border. Therefore the very existence of immigrants and their basic right to be in the US is undermined.

Influences of infrastructure and attitudes to health on value of travel time savings in bicycle journeys

In this paper we investigate how attitudes to health and exercise in connection with cycling influence the estimation of values of travel time savings in different kinds of bicycle environments (mixed traffic, bicycle lane in the road way, bicycle path next to the road, and bicycle path not in connection with the road). The results, based on two Swedish stated choice studies, suggest that the values of travel time savings are lower when cycling in better conditions. Surprisingly, the respondents do not consider cycling on a path next to the road worse than cycling on a path not in connection to the road, indicating that they do not take traffic noise and air pollution into account in their decision to cycle. No difference can be found between cycling on a road way (mixed traffic) and cycling in a bicycle lane in the road way. The results also indicate that respondents that include health aspects in their choice to cycle have lower value of travel time savings for cycling than respondents that state that health aspects are of less importance, at least when cycling on a bicycle path. The appraisals of travel time savings regarding cycling also differ a lot depending on the respondents’ alternative travel mode. The individuals who stated that they will take the car if they do not cycle have a much higher valuation of travel time savings than the persons stating public transport as the main alternative to cycling.

Analytical form of the Probability Density Function of travel times in rectangular zone with Tchebyshev’s metric

Geometrical dependencies are being researched for analytical representation of the probability density function (pdf) for the travel time between a random, and a known or another random point in Tchebyshev’s metric. In the most popular case - a rectangular area of service - the pdf of this random variable depends directly on the position of the server. Two approaches have been introduced for the exact analytical calculation of the pdf: Ad-hoc approach – useful for a ‘manual’ solving of a specific case; by superposition – an algorithmic approach for the general case. The main concept of each approach is explained, and a short comparison is done to prove the faithfulness.

Irritable bowel syndrome (IBS) in U.S. adult travelers': The importance of travel to the development of IBS

Background. Irritable bowel syndrome is a gastrointestinal disorder that is potentially linked to international travel at an undetermined frequency.^ Methods. A self-administered questionnaire was distributed through mail to five hundred and ninety-one patients that were twice diagnosed with irritable bowel syndrome at Kelsey Seybold Clinic in Houston, TX. Responses to survey questions were used to assess patient travel history, IBS symptomology, and disease classification.^ Results. Of the five hundred and ninety-one patients that were mailed a questionnaire, two hundred and twenty one patients returned questionnaires and two hundred and one met inclusion criteria. Of the participants reporting international travel within six months of developing their chronic intestinal disorder, 60% were classified as having PI-IBS, while 25% had IBS, 10% had PI-UFBD, and 5% had UFBD. A majority of the subjects who traveled six months before onset of their functional bowel disease had a post-infectious form of IBS and reported a start and worsening of symptoms with an acute bout of diarrhea. It was common for those traveling six months before travel and labeled PI-IBS to have enteric symptoms that led to lifestyle adjustments. ^ Conclusion. International travel had a significant effect on the classification of IBS among patients which relates to the differences in IBS symptoms and perhaps pathogenesis among travelers versus non-travelers. ^

FATS: a framework for annotation of travel blogs based on subjectivity

This paper describes a framework for annotation on travel blogs based on subjectivity (FATS). The framework has the capability to auto-annotate -sentence by sentence- sections from blogs (posts) about travelling in the Spanish language. FATS is used in this experiment to annotate com- ponents from travel blogs in order to create a corpus of 300 annotated posts. Each subjective element in a sentence is annotated as positive or negative as appropriate. Currently correct annotations add up to about 95 per cent in our subset of the travel domain. By means of an iterative process of annotation we can create a subjectively annotated domain specific corpus.
