The use of the 4D trajectory operational concept in the future air traffic management (ATM) system will require the aircraft to meet very accurately an arrival time over a designated checkpoint. To do this, time intervals known as time windows (TW) are defined. The purpose of this paper is to develop a methodology to characterise these TWs and to manage the uncertainty associated with the evolution of 4D trajectories.

4D trajectories are modelled using a point mass model and EUROCONTROL’s BADA methodology. The authors stochastically evaluate the variability of the parameters that influence 4D trajectories using Monte Carlo simulation. This enables the authors to delimit TWs for several checkpoints. Finally, the authors set out a causal model, based on a Bayesian network approach, to evaluate the impact of variations in fundamental parameters at the chosen checkpoints.

The initial results show that the proposed TW model limits the deviation in time to less than 27 s at the checkpoints of an en-route segment (300 NM).

The objective of new trajectory-based operations is to efficiently and strategically manage the expected increase in air traffic volumes and to apply tactical interventions as a last resort only. We need new tools to support 4D trajectory management functions such as strategic and collaborative planning. The authors propose a novel approach for to ensure aircraft punctuality.

The main contribution of the paper is the development of a model to deal with uncertainty and to increase predictability in 4D trajectories, which are key elements of the future airspace operational environment.

The purpose of this paper is to provide an analysis of a post-project review (PPR) method designed to verify the accomplishments of urban disaster risk reduction-neighborhood approach (DRR-NA) projects after at least one year of project closeout. The PPR revisited the essential processes identified during project implementation and analyzed the sustainability of project gains.

The first section focuses on a literature review of the evaluation methods after project implementation, and the second describes the urban risk PPR design, its implementation, and findings.

The proposed framework for the PPR was clear and uniform and at the same time offered the necessary flexibility to adapt to the different DRR-NA projects and contexts. The PPR methodology sought to determine the conditions of the physical works, social and environmental gains, and progress in institutional arrangements associated with the NA projects. Factors that contribute and impede success in DRR-NA projects were identified.

Allowing at least one year between the completion of the NA projects and the PPR is both convenient and challenging. On the positive side, this approach allows for the verification of project outcomes after an extended period of time. However, there are also challenges, such as the need to seek additional financial resources to carry out the review; generate new contractual mechanisms; and assign human resources to review a project already closed.

The changes introduced into the PPR methodology to obtain a participative and self-conducted process resulted in a truly collective learning experience, becoming an act of accountability and social commitment.

The purpose of this paper is to explore the current and projected impacts of the three post-2015 development agendas on the underlying disaster risk drivers (UDRD): the Sendai Framework for Disaster Risk Reduction, the Sustainable Development Goals, and the Paris COP21 Agreement.

The methodology is based on an ontological process, understood as an exhaustive analysis of the properties and relationships of an entity or subject of study.

The process characterized and linked the objectives proposed in the three agendas through the impact of the expected results on the underlying risk drivers. First, elements related to disaster risk within each agenda were identified. Then, in following the theory of change, a series of tools were used to identify domains of change, pathways, breakthroughs, and incremental outcomes that counteract the construction of disaster risk by acting on the underlying causes. It is essential that there be coherence, complementarity, and interdependence between the three agendas analyzed in order to transcend beyond the desired economic growth, and thus underpin true sustainable development by focusing on the UDRD.

Applying the theory of change constitutes a novel approach to identify the pathways or domains of change needed to integrate the three 2015 development agendas.

This his paper focuses on a specific aspect of Value‐Based Management (VBM), the design of performance measurement systems. This remains an important challenge not only in Management Accounting but also in Human Resources Management. Performance measurement on various levels of organisation should be aligned to value creation, and management compensation should be tied to the achievement of targets set to these measures according to VBM proponents. In the present article definitions of concepts and issues associated with the design of performance measurement systems are discussed. Furthermore, the paper presents a review of four tools available to measure and manage intangible resources: human resource accounting, economic value‐added (EVA), balanced scorecard (BSC) and intellectual capital (IC). The role of non‐financial measures is also analysed from a VBM framework. Finally, some concluding remarks are highlighted in the last section.

NASCAR (The National Association for Stock Car Auto Racing) has instituted an aggressive growth campaign. NASCAR's compelling challenge is to retain its core fan base - south-eastern US consumers - while also attracting a new upscale demographic and an international following. One targeted initiative was a three-year commitment to feature the NASCAR Busch Series at the Autodromo Hermanos Rodriguez, near Mexico City. This paper explores the assimilation of NASCAR's core product into a Hispanic subculture, observes the media's depiction of the expansion, and discusses the US fan reaction to racing in Mexico.

This study aims to assess knowledge retention of the graduates of the online graduate certificate on local development planning, land use management and disaster risk management (PDLOTGR, the abbreviation of the certificate's Spanish title). The certificate was offered to practitioners and faculty members of Latin American countries since 2016.

The authors reviewed the knowledge, attitude and practice (KAP) method to develop a specific approach, which included the preparation of a KAP survey, a composite KAP index and three sub-indices. The survey targeted two groups: (1) experimental group, composed of the certificate's 76 graduates, and (2) control group, comprised of 25 certificate's candidates, who had not yet undergone the training/intervention. The statistical analysis included a one-way multivariate analysis of variance to compare the mean scores on the KAP index and sub-indices for individuals in the experimental and control groups.

The study results showed significant differences in the knowledge sub-index between those who had completed the PDLOTGR training and those who had not, while the attitudes and practices sub-indices did not show significant differences. When using the KAP index, a statistically significant difference was also observed between the two groups.

Perceived knowledge assessment offers an acceptable and non-intimidating option for evaluating continuing education and professional development programs associated to disaster risk. It is particularly helpful in determining whether an intervention or program has a lasting impact. It is not, however, a substitute for direct knowledge assessment, and the use of other methods to evaluate the performance of a capacity building program's graduates.
