Purpose — In this chapter the three household travel survey methods PAPI (paper and pencil interview), CATI (computer-assisted telephone interview), and CAWI (computer-assisted web interview) are compared in order to show well-known and new methodological effects.

Methodology/approach — The survey concept in the Stuttgart region with the three methods (PAPI, CAPI, and CAWI) offers the possibility to analyze the differences between these methods. This approach offers various possibilities to compare the subsamples and to evaluate the effects of the different survey methods in order to ensure a high data quality.

Findings — The results show a clear tendency that retired people prefer the CATI design instead of CAWI, while younger persons prefer the CAWI design. The PAPI design seems to cover all parts of the population to the same extent and also achieves the same response levels as CATI and CAWI.

Originality/value of chapter — The three different survey methods within one survey allow on the one hand methodological analyses without distortion of results by different framework conditions. On the other hand the CATI and CAWI survey methods are relatively new in the field of multiday surveys especially in Germany.

The purpose of this study is to examine the effect of monitoring local authorities on the quality of governance and public services reported by citizens in Vietnam, using the Vietnam Governance and Public Administration Performance Index (PAPI) surveys.

PAPI randomly selected 200 locations in 93 districts of 30 provinces to conduct its survey in 2010, and subsequently rolled out the survey nationally in 2011 and 2012. Using 2011 and 2012 survey data, the authors compare the quality of governance and public services reported in provinces and districts that were covered in the 2011 PAPI survey with those that were not surveyed in 2010. Theories suggest that local authorities may improve their behavior if they have been surveyed and are, thus, aware that they are being monitored, leading to higher quality governance.

In this paper, the authors find that governance quality reported in later years by citizens in the surveyed provinces and districts of the 2010 PAPI survey was significantly higher than the quality reported by citizens in locations that were not surveyed in 2010. Monitoring appears to improve a wide range of governance aspects, including local participation in village decisions, transparency of local decision-making, accountability, administrative procedures and public service delivery.

The main innovation of this study is to use a randomized survey on governance as a natural experiment to measure the impact of monitoring on the quality of governance and public services, as reported by citizens.

Single-party regimes increasingly use Subnational Performance Assessments (SPAs) – rankings of provinces and districts – to improve governance outcomes. SPAs assemble and publicize information on local government performance to facilitate monitoring and generate competition among officials. However, the evidence are sparse on their effects in this context. The authors argue that built-in incentive structures in centralized single-party regimes distort the positive impact of SPAs.

The staggered rollout of the Vietnam Provincial Governance and Public Administration Performance Index (PAPI) created a natural experiment. Due to 2010 budget constraints, the first iteration of the PAPI survey covered only 30 of Vietnam’s 63 provinces before covering all in 2011. The PAPI team used matching procedures to identify a statistical twin for each province before randomly selecting one from each pair. The authors use randomization inference to compare the outcomes of these control and treatment groups in 2011.

Exposure to PAPI helped improve almost all aspects of governance; however, significant evidence of prioritization bias exist. The positive effects only persisted for the dimension of administrative procedures, which was the one area of governance that was prioritized by the central government at the time. Other dimensions only registered short-term effects.

Our study provides an examination of the impact of SPAs in a single-party regime context. In addition, the authors leverage the natural experiment to identify information effects causally. The authors also look past short-term effects to compare outcomes for five years after the treatment occurred.

The fusion energy research in Europe is developed by a set of laboratories of different countries and organisations. EFDA is an organisation whose main objective is to promote and improve the coordination and collaboration among these laboratories. This paper sets out to describe a working federation (EFDA‐Fed) that gathers EFDA (as organisation) and a set of fusion research laboratories: EURATOM/CIEMAT (Spain), CEA (France), JET (UK), IST (Portugal) and KFKI/HAS (Hungary).

To achieve the objective a federation among all the organisations has been implemented based on PAPI as the authentication and authorization infrastructure that provides a security layer for accessing data among organisations.

During the implementation of EFDA federation some improvements in distributed single sign on systems have been achieved such as the integration of JAVA applications and a single sign off mechanism.

Users who belong to one of the federated organisations will be able to access from any IP address to resources located in any organisation of the federation in a secure way. On the other hand, new resources can be shared for federated users and access policies to these services can be implemented.

The paper describes a successful use of an open source technology (PAPI) for implementing a real multi‐organisation infrastructure for sharing services in a secure way, and integrating client applications and with a complete single sign off mechanism.

This paper aims to present a vision-based method for determination of the position of a fixed-wing aircraft that is approaching a runway.

The method determines the location of an aircraft based on positions of precision approach path indicator lights and approach light system with sequenced flashing lights in the image captured by an on-board camera.

As the relation of the lighting systems to the touchdown area on the considered runway is known in advance, the detected lights, seen as glowing lines or highlighted areas, in the image can be mapped onto the real-world coordinates and then used to estimate the position of the aircraft. Furthermore, the colours of lights are detected and can be used as auxiliary information.

The presented method can be considered as a potential source of flight data for autonomous approach and for augmentation of manual approach.

In this paper, a feasibility study of this concept is presented and primarily validated.

A new visual landing aid for civil and military aircraft conceived and developed at RAE Bedford seems set to be adopted by the international aviation community. The Precision Approach Path Indicator (PAPI) system has just gone on trial at London's Heathrow Airport as part of a Civil Aviation Authority evaluation programme, in which both the British Airports Authority and the RAE are assisting.

This paper aims to develope the electromagnetic interference shielding materials with high performance. To develop advanced polymer-based electromagnetic interference shielding materials with rather high temperature stability, good processability and moderate mechanical properties, the authors chose the polyimide (PI) foam as matrix and ferriferrous oxide (Fe₃O₄) as fillers to prepare the composite foams with lightweight and rather good electromagnetic interference shielding performance.

Some polyimide nanocomposite foams with Fe₃O₄ as fillers have been prepared by in situ dispersion and foaming with pyromellitic dianhydride (PMDA) and isocyanate (PAPI) as raw materials and water as foaming agent. By varying the Fe₃O₄ contents, a series of PI/Fe₃O₄ nanocomposite foams with fine microstructures and high thermal stability were obtained. The structure and performances of nanocomposite foams were examined, and the effects of Fe₃O₄ on the microstructure and properties of composite foams were investigated.

This work demonstrates that PI/Fe₃O₄ foams could be fabricated by thermally treating the polyimide foam intermediates with Fe₃O₄ nanoparticles through a blending reaction of precursors. The final PI/Fe₃O₄ composite foams maintained the excellent thermal property and showed a super paramagnetic behaviour, which has a positive effect on the improvement of electromagnetic shielding performance.

In this paper, the effects of Fe₃O₄ on the performances of PI/Fe₃O₄ composite foam were reported. It provided an effective methodology for the preparation of polymer/Fe₃O₄ nanocomposite foams, which hold great promise towards the potential application in the areas of electromagnetic shielding materials.

A series of PI/Fe₃O₄ composite foams with different contents of Fe₃O₄ were prepared by blending reaction of the precursors. The effects of Fe₃O₄ on the structures and properties of PI/Fe₃O₄ composite foam were discussed in detail.

A TriStar was inbound to Leeds/Bradford and on first contact with the aircraft, the controller at the airport reported the present weather which included a visibility of 7,000 metres, wind velocity 210°/7 knots and recent rain showers, he also advised that the runway in use was 14 and that the surface was wet. Although the captain had the runway in sight at 7 miles, he elected to fly a surveillance radar approach and was accordingly advised by the controller of the touchdown elevation and that the glide slope for runway 14 was 3½°. The approach was normal and at 2 miles from touchdown the captain notified the radar controller that he was continuing visually. The aircraft changed to tower frequency on which the controller passed the current surface wind of 210°/7 knots and cleared the aircraft to land. The captain stated afterwards that he used radar talk‐down heights to establish his glide path and confirmed it by the Precision Approach Path Indicators (PAPIs) which consistently showed two whites and two reds until the last 200 feet, when he deliberately descended into one white and three reds so as to use the maximum runway length.
