And Performance

The aim of this paper is to design an approach to evaluate the expected efficiency and performance of future airport infrastructure. First, an airport sampling method to select similar airports is developed based on socioeconomic and operational airport variables that are summarized in a proxy variable; second, the ARIMA-GARCH-Bootstrap method is applied to forecast the selected outputs (PAX and ATMS) whilst the selected inputs (Cities, Gates, Runaways, Airport Size, Pax carriers, and Num. of employees) remain constant; and third, the VRS-OO and the CRS-OO DEA models are implemented to evaluate the efficiency and performance of the airports in the current and future years. The proposed approach is used to evaluate the future airport infrastructure of the new Mexico City Airport against 19 representative worldwide airport hubs. The proposed approach is applied to analyze the Mexico City Airport multi-airport system infrastructure as a case study. The results show that this multi-airport system requires more airside infrastructure that must be added by the new Mexico City Airport, airlines should operate aircrafts with more capacity to serve more PAX per ATM, and airlines must open new connections at the new Mexico City Airport to increase the expected efficiency and performance of this multi-airport system.

The Impact

The introduction of new Air Traffic Management (ATM) concepts such as Trajectory Based Operations (TBO) may produce a significant impact in all performance areas, that is, safety, capacity, flight efficiency, and others. The performance framework in use today has been tailored to the operational needs of the current ATM system and must evolve to fulfill the new needs and challenges brought by the TBO content. This paper presents a novel performance assessment framework and methodology adapted to the TBO concept. This framework can assess the key performance areas (KPAs) of safety, capacity, and flight efficiency; equity and fairness are also considered in this research, in line with recent ATM trends. A case study is presented to show the applicability of the framework and to illustrate how some of the complex interdependencies among KPAs can be captured with the proposed approach. This case study explores the TBO concept of “strategic 4D trajectory deconfliction,” where the early separation tasks of 4D trajectories at multisector level are assessed. The framework presented in this paper could potentially support the target-setting and performance requirements identification that should be fulfilled in the future ATM system to ensure determined levels of performance.

The Impact

PurposeThe main purpose of this study is to provide a decision-making basis for the development of a sustainability strategy by importance-performance analysis (IPA) methods. However, traditional and modified IPA methods do not accurately reveal the impact of the various dimensions of sustainable development (SD) on cultural landscape (CL). Based on the structural equation model (SEM), four main dimensions of SD were identified from the available data. This paper conducted an optimized IPA by building three SEMs based on importance, performance and the importance of four dimensions.Design/methodology/approachThis paper proposes the use of exploratory factor analysis (EFA) and SEM to develop the CL characteristic index evaluation model to determine the load of each indicator of importance and performance, and the SD-based measurement model to further determine the weight of the sustainability of each indicator in importance and performance. Afterwards, proposed sustainable strategies to the corresponding index were obtained.FindingsThis study offers useful insights into the actual operation and theoretical aspects of the IPA method.Practical implicationsThis study offers useful insights into the actual operation and theoretical aspects of the IPA method. This can solve the incongruous and uncertainty problem in the sustainable planning strategy, and the case study proves the feasibility of the IPA method combined with the influence of the structural equation.Social implicationsThe research is conducive to acceptance by local people with regard to their preferences in the perspective of sustainable development. It provides a basis for the future use of the IPA method in a comprehensive way based on an administrative angle.Originality/valueThe case study proves the feasibility of the IPA method combined with the influence of the structural equation. This provides a basis for the future use of the IPA method in a comprehensive way based on an administrative angle.

Despite their cultural and economic importance, creative micro-enterprises have received very little attention from academia research, especially with respect to vertical co-operation—customers and suppliers—and innovation. This study aims to fill the literature gap by studying how vertical co-operation improves the performance of micro-enterprises in textile crafts through innovation. A questionnaire was used to collect data from creative micro-enterprises in the textile craft sector operating in the Matiari District of Pakistan. To test the construct validity of the research, Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were conducted, and to examine the hypotheses, the bootstrap re-sampling method was used with the SPSS PROCESS macro developed by Hayes. The findings of this study indicate that vertical co-operation positively and significantly affects the innovation and performance of creative micro-enterprises in textile crafts. In addition, we find that innovation plays a significant mediating role between vertical co-operation and performance. Furthermore, contrary to some studies, we empirically provide evidence regarding innovation in craft in terms of product development (design, size, shape, color, etc.), improvement in quality, and replacement/modification of tools.

Point Of Departure

There is a pressing need to extend our thinking about diplomacy beyond state-centric perspectives, as in the name of sovereignty and national interests, people on move are confronting virtual, symbolic and/or material walls and frames of policies inhibiting their free movement. My point of departure is to explore migrant activism and global politics through the transformation of diplomacy in a globalised world. Developing an interdisciplinary dialogue between new diplomacy and sociology, I evidence the emergence of global sociopolitical formations created through civic bi-nationality organisations. Focusing on the agent in interaction with structures, I present a theoretical framework and strategy for analysing the practices of migrant diplomacies as an expression of contemporary politics. A case study from North America regarding returned families in Mexico City provides evidence of how these alternative diplomacies are operating.

Event Based

The growth of the event sector is underpinned by the demand of organizing a business event.  Thus, it leads to an increase in economic and social impact. However, the problems from the growth of this sector potentially results from the use of several event materials, transportation and infrastructure development.  Organizing a green event is seen as one of the strategies to reduce the environmental impact.  Therefore, the aim of this paper is to explore the issues involved throughout the process of greening an event by applying Mair and Jago Model.  Semi-structured interviews were conducted with event managers from six Malaysia business event companies that encourage green practices during their event.  Findings suggest that impact, initiative, support and performance motivates event organizers in organizing a green event.  It has also been found that knowledge, resources and behaviour are the barriers faced by event organizers throughout the process of organizing a green event.  Based on the findings it appears that two important factors have emerged from the data collection and analysis that showed a deviation from the Mair and Jago Model, namely “impact” for the motivation element and “support” for the barrier element.  The main limitation of this study was the scope of the study; as it only focuses on business events.  However, as the main purpose of this study is to explore the issues of organizing a green event, it has been found that there are other issues need to be explored in other contexts and geographical area.  Apart from this, as this is a case study, it can only replicate according to the circumstances of this case study. However, this study can be generalized in terms of the theory that has emerged from it.  It is suggested that further research should explore more issues in other contexts and geographical areas.
