The tourism footprint family comprises the tourism ecological footprint (TEF), the tourism carbon footprint (TCF) and the tourism water footprint (TWF). The tourism footprint represents an important tool for quantitatively assessing the impact of tourism activities on the ecosystem of a tourist destination. This paper systematically reviews the relevant literature on TEF, TCF and TWF, analyses ...

BACKGROUND This cadaveric study aimed to demonstrate variation of the anterior cruciate ligament (ACL) tibial attachment in the sagittal plane, and to analyze the radiographic landmarks which predict the sagittal location of the ACL tibial attachment. METHODS In 20 cadaveric knees, native ACLs were removed and the centers of the ACL tibial and femoral attachments were marked with metal pins. ...

BACKGROUND Traditional Bankart repair using bone tunnels has a reported failure rate between 0% and 5% in long-term studies. Arthroscopic Bankart repair using suture anchors has become more popular; however, reported failure rates have been cited between 4% and 18%. There have been no satisfactory explanations for the differences in these outcomes. HYPOTHESIS Bone tunnels will provide increas...

In Escherichia coli, the MetR and PurR proteins positively and negatively regulate glyA gene expression, respectively. A DNase I footprint analysis showed that both proteins bind independently to the glyA control region. The PurR protein blocks RNA polymerase (RNAP) from binding to the glyA promoter. The presence of hypoxanthine, the co-repressor of PurR, increases the ability of PurR to preven...

Article history: Received 26 September 2007 Received in revised form 2 June 2008 Accepted 19 June 2008 Available online 8 August 2008 The water footprint concept introduced in 2002 is an analogue of the ecological footprint concept originating from the 1990s. Whereas the ecological footprint (EF) denotes the bioproductive area (hectares) needed to sustain a population, the water footprint (WF) ...

[1] A spatially explicit life cycle water analysis framework is proposed, in which a standardized water footprint methodology is coupled with hydrologic modeling to assess blue water, green water (rainfall), and agricultural grey water discharge in the production of biofuel feedstock at county-level resolution. Grey water is simulated via SWAT, a watershed model. Evapotranspiration (ET) estimat...

extended abstract 1. introduction tourism industry is known as one of the most thriving, attractive, job- creating and greatest industries in third millennium. the growth of this industry, despite its many positive economic advantages for hosting communities, has had some adverse consequences particularly on environmental aspects that have led to increased concerns among the experts and planner...

This paper describes and evaluates CONSPECT (from concept inspection), an application that analyses states in a learner’s conceptual development. It was designed to help online learners and their tutors monitor conceptual development and also to help reduce the workload of tutors monitoring a learner’s conceptual development. CONSPECT combines two technologies Latent Semantic Analysis (LSA) and...

A new area in which passive WiFi analytics have promise for delivering value is the real-time monitoring of public transport systems. One example is determining the true (as opposed to the published) timetable of a public transport system in real-time. In most cases, there are no other publicly-available sources for this information. Yet, it is indispensable for the real-time monitoring of publ...
