Expansion of congested railway capacity using triple-track line operation based on hourly passenger demand

This paper proposes a method of improving level of service in congested urban railways by means of a triple-track line operation for a highly dense urban area with special travel demand characteristics. Where the future travel demand forecasts show sluggish growth or no growth at all, there is little to no incentives for heavy railway investments like quadruple-track extension and construction of new railway routes to alleviate current railway congestion problems. In such a situation, triple-track line operation can be the best alternative due to its moderate investment cost and ease in land acquisition for just an additional single track along the existing tracks. Our simulation investigation in one of the congested railway lines in Tokyo showed that triple track line operation increases railway capacity by 26% and shortens travel time by 38% in peak direction during morning peak hours. These results are encouraging and are useful for removing current railways problems in Tokyo and in similar urban situations elsewhere.

Using Pareto principle plus statistic methodology in establishing a cost estimating model

Previous experience and research indicated that the Pareto Principle (80/20 Principle) has been widely used in many industries to achieve more with less. The study described in this paper concurs that this principle can be applied to improve the estimating accuracy and efficiency, especially in design development stage of projects. In fact, establishing an effective cost estimating model to improve accuracy and efficiency in design development stage has been a subject, which has attracted many research attentions over several decades. For over almost 40 years, research studies indicate that using the 80/20 Principle is one of the approaches. However, most of these studies were built by assumption, theoretical analysis or questionnaire survey. The objective of this research is to explore a logical and systematic method to establish a cost estimating model based on the Pareto Principle. This paper includes extensive literatures review on cost estimating accuracy and efficiency in the construction industry that points out the current gap of knowledge area and understanding of the topical. These reviews assist in developing the direction for the research and explore the potential methodology of using the Pareto Principle in the new cost estimating model. The findings of this paper suggest that combining the Pareto Principle with statistical analysis could be used as the technique to improve the accuracy and efficiency of current estimating methods in design development stage.

Triple G girls get going in tennis : resource manual

Physical activity is ranked second in importance only to tobacco control in health promotion and disease prevention in Australia. Individuals can be active in many ways every day, including –walking to and/or from school, work and other places of interest; participating in sports clubs; going to the YMCA or community leisure centre where you can be active through gyms, group fitness classes or in the swimming pool; visiting local parks and walking trails, and even at home and in the backyard. You can always find ways to be active in the community.

Promoting physical activity to young people is important for developing healthy lifestyles now and maintaining them for the future. A physically active lifestyle can be of benefit to physical, mental and social health. Despite these benefits, adolescent girls and young women are considerably less active than their male counterparts, and sport participation decreases dramatically among girls during their secondary school years. Many physical education teachers have also expressed concern about girls minimising their participation in school physical education. Consequently, it is timely that a project such as Triple G ‘Girls Get Going in Tennis, in Football, and at the YMCA’ should be developed and implemented in an effort to arrest the decline in girls’ participation in sport, physical activity and physical education.

The Triple G program aims to develop, implement and evaluate a program to promote participation in physical activity by girls in rural and regional schools and communities. The impact of the Triple G program on the mental and physical wellbeing of the girls will also be evaluated. The program specifically aims to create school and community linkages through the introduction of tennis coaches, football coaches, and YMCA instructors into the physical education class to team teach with physical education staff during the 2011 school year. As part of the school-based program, Year 7 – 9 girls will participate in a YMCA unit and one of tennis or football during their physical education classes (6 sessions x 100mins each). Each unit is then followed by an eight week afterschool program at the local tennis or football club, or YMCA centre.

Fidelity to foraging sites, consistency of migration routes and habitat modulation of home range by sea turtles

Aim  Resources can shape patterns of habitat utilization. Recently a broad foraging dichotomy between oceanic and coastal sites has been revealed for loggerhead sea turtles (Caretta caretta). Since oceanic and coastal foraging sites differ in prey availability, we might expect a gross difference in home-range size across these habitats. We tested this hypothesis by equipping nine adult male loggerhead sea turtles with GPS tracking devices. Location  National Marine Park of Zakynthos (NMPZ) Greece, central and eastern Mediterranean (Adriatic, Ionian and Aegean seas). Methods  In 2007, 2008 and 2009, Fastloc GPS-Argos transmitters were attached to nine male loggerheads. In addition, a Sirtrack PTT unit was attached to one male in 2007. Four of the turtles were tracked on successive years. We filtered the GPS data to ensure comparable data volumes. Route consistency between breeding and foraging sites of the four re-tracked turtles was conducted. Foraging site home range areas and within site movement patterns were investigated by the fixed kernel density method. Results  Foraging home range size ranged between circa 10 km2 at neritic habitats (coastal and open-sea on the continental shelf) to circa 1000 km2 at oceanic sites (using 90% kernel estimates), the latter most probably reflecting sparsely distributed oceanic prey. Across different years individuals did not follow exactly the same migration routes, but did show fidelity to their previous foraging sites, whether oceanic or neritic, with accurate homing in the final stages of migration. Main conclusions  The broad distribution and diverse life-history strategies of this population could complicate the identification of priority marine protected areas beyond the core breeding site.

The common law principle of legality

In this age of statutes and human rights the common law principle of legality has assumed a central importance. The principle holds that '[u]nless the Parliament makes unmistakably clear its intention to abrogate or suspend a fundamental freedom, the courts will not construe a statute as having that operation.' This development has occurred throughout the common law world most relevantly in New Zealand and the United Kingdom where its re-emergence coincided with the enactment of statutory bill of rights. It is however the aim of this article to outline the nature and scope of the principle of legality in contemporary Australian law.

Consistency and stability in aggregation operators : an application to missing data problems

In this work we analyze the key issue of the relationship that should hold between the operators in a family {An} of aggregation operators in order to understand they properly define a consistent whole. Here we extend some of the ideas about stability of a family of aggregation operators into a more general framework, formally defining the notions of i – L and j – R strict stability for families of aggregation operators. The notion of strict stability of order k is introduced as well. Finally, we also present an application of the strict stability conditions to deal with missing data problems in an information aggregation process. For this analysis, we have focused in the weighted mean family and the quasi-arithmetic weighted means families.
