A total of 196 schools participated in the Tier 1 Program (Secondary 2 curriculum) of the Project P.A.T.H.S. in Hong Kong. After the completion of the program, 1,178 instructors completed a subjective outcome evaluation form to assess their views of the program, instructors and perceived effectiveness of the program. Results showed that high proportions of the instructors had positive perceptio...

ScotGrid [1] is a prototype regional computing centre formed as a collaboration between the universities of Durham, Edinburgh and Glasgow as part of the UK’s national particle physics grid, GridPP [2]. We outline the resources available at the three core sites and our optimisation efforts for our user communities. We discuss the work which has been conducted in extending the centre to embrace n...

We present the results of performance tests to compare two protocols for three-tier computing using the Windows NT operating system. Three-tier computing features a data server for stored databases (Tier I) , an application server that runs applications (Tier 2), and a simple client program that runs on desktop machines that presents the user interface (Tier 3). Three protocols are available to...

The most reliable test method for the serological confirmation of Lyme disease (LD) is a 2-tier method recommended by the CDC in 1995. The first-tier test is a low-specificity enzyme-linked immunosorbent assay (ELISA), and the second-tier tests are higher-specificity IgG and IgM Western blots. This study describes the selection of two Borrelia burgdorferi recombinant proteins and evaluation of ...

A large number of health plans and employers have adopted three-tier prescription drug formularies in an effort to control rising prescription drug costs. We assessed the behavioral response to three-tier adoption by estimating econometric models of the probability of selecting drugs assigned to the third tier with the highest co-payment requirement and changes in expected out-ofpocket (OOP) sp...

Femtocells Access Points (FAP) are low power, plug and play home base stations which are designed to extend the cellular radio range in indoor environments where macrocell coverage is generally poor. They offer significant increases in data rates over a short range, enabling high speed wireless and mobile broadband services, with the femtocell network overlaid onto the macrocell in a dual-tier ...

HAS Network Medium I Abstract A three-tier gateway architecture for internetworking between home automation networks and a TCPlIP based wide area network, such as the internet, is described. The architecture abstracts the functionality of any home network into a driver layer (tier one), and provides a common access layer (tier two) from any TCP/IP network application (tier three) to a local hom...

— While biotechnology innovation is concentrated in high income, ‘‘Tier I’’ countries, international diffusion of innovations to improve the diet, health, and incomes of the poorest will be largely driven by ‘‘Tier II’’ innovators such as China and Brazil. Adoption of beneficial biotechnologies in ‘‘Tier II’’ and ‘‘Tier III’’ countries will increase as more transgenic versions of conventionally...

We study status as it pertains to loyalty programs, investigating the impact of the number and size of tiers on consumers’ perceptions of status. We find that increasing the number of elites in the top tier dilutes perceptions of status, while adding a subordinate tier enhances status. Tiers below the second tier do not affect those at the top but can make those in the tier immediately above fe...
