Performance differences between the aircraft types are natural and they inevitably cause problems in the air traffic system, particularly when slower aircraft types are followed by faster types in a climb or cruise queue. This paper presents the excess fuel consumption impact of aircraft performance differences in the air traffic environment. For this purpose, both climb and cruise phases of a flight mission are analyzed. Revision of the airworthiness regulations and air traffic procedures are suggested. The need for a flight level – cruise performance categorization is also recommended.

The progressive utilization of information necessitates the evaluation of the information‐content of scientific documents over conventional bibliotechnical indexing‐operations. The technique of optimal economical evaluation of information rests in the alternative between the keyword and subject‐index as the symbolic operator. From the analysis of 350 scientific documents the keyword‐concept was, by empirical decision, derived to be the superior operator. Conversely, the concept of subject‐indexing leads to ambiguities of subcategories, since certain branch‐nodes of the categorical trees (code trees) may belong to several simultaneous subject‐categories. This ambiguity can be resolved only by means of coordination‐tables correlating each keyword with the pertinent simultaneous subject‐categories. The application of synonym‐registers affects the concentration of information‐sources with typical completeness for each keyword‐entry in the system. The phrasing of syntactically associated keywords produces a significant precision of the information‐content of the documentary text. The efficiency of a documentary system is predominantly accomplished by information‐filtering in terms of relevant keyword‐phrases. This system‐efficiency is displayed as a function of utility‐rate versus precision‐rate, which is considered superior to Salton's efficiency‐rate of “precision versus recall.” The phrasing of key‐word‐phrases is utilized as the structure for the design of a truly topic‐related abstract to any document. Empirical findings from this study of economical optimization of documentary systems reveal the actual efficiency of the concept of information‐evaluation.

This study aims to evaluate the impact of Law No. 11 of 2018 on Islamic Financial Institutions in Aceh, Indonesia. It also aims to understand the balance between the economic rights of individuals under Shariah law and the broader concept of God’s rights, as interpreted by this legislation. In addition, the research argues that the implementation of Law No. 11 of 2018 is untimely, with a focus on examining its influence on the cumulative abnormal return (CAR) of Shariah banks and its slight contribution to the direct economic impact.

This study adopts a mixed-methods approach that integrates qualitative and quantitative analyses. The qualitative aspect uses a black-letter law approach for legislative scrutiny, whereas the quantitative aspect assesses economic indicators and firm performance using an event study analysis. The study also includes a two-tailed assessment to test hypotheses related to the law’s direct impact on institutional performance.

The study reveals that Law No. 11 of 2018 had minimal impact on national-scale corporate performance and a notable increase in poverty indices in Aceh, indicating a potential misalignment between the law’s intention and its economic consequences. The results also show the law’s ineffectiveness in significantly influencing the CAR of Islamic banks, highlighting a clash of norms and a lack of substantial economic substance in the implementation of Shariah compliance.

This research is geographically and legally focused on Aceh, Indonesia, with a short-term analysis that may not fully capture the long-term impacts. It primarily considers the stock price performance of specific institutions for quantitative analysis and identifies potential clashes and disharmony-in-law implementation from a qualitative perspective.

The findings suggest the need for legal frameworks that better comply Shariah principles with economic realities. Regional governments should consider modifying policies to balance religious values and economic objectives.

This research highlights the importance of balancing religious obligations with economic rights, indicating that strict interpretations of religious law can lead to adverse socioeconomic effects.

This study is unique in its comprehensive analysis of the convergence between religious law and economic rights, offering insights into the challenges faced in implementing Shariah-based economic policies in diverse economies, such as Indonesia.

Sustainability as a construct is still debated and is yet to attain a consensus among researchers and practitioners. Sustainable development has been seen differently by players from different industry sectors. There is need to understand the commonality prevailing on sustainability practices across different industry sectors to arrive at a consensual sustainability definition. The purpose of this paper is to propose four dimensions of sustainability and studies how it captures sustainability practices across key industrial sectors.

Current study argues the case for sustainability using four constructs, namely, economical, environmental, ethical, and social. Subsequently a holistic definition with a model is proposed incorporating the four constructs for sustainability. Studies documenting sustainability practices across industries, namely, automobile, infrastructure, cement and concrete, electronics, mining, paper, pharmaceutical, and logistics were reviewed to validate the applicability of the proposed four construct model across different key industrial sectors.

Current study validates the industry independence of the proposed four constructs of sustainability model through a literature review. Very few studies have documented industry-specific sustainability practices and much lesser have studied the ethical dimension of sustainability. Furthermore, the organizational strategic plan is developed for incorporating the environmental, economical, ethical, and social needs into the organizational business operations at the strategic, tactical, and the operational levels.

Proposed model needs to be applied in multiple case organizations from diverse sectors to evaluate its capacity to capture the aspects of sustainability across different sectors. Future study could attempt to understand the interrelationships between the identified constructs and how they impact each other within different industrial sectors.

Model linked to organizational business operations at the strategic, tactical, and the operational levels helps in the alignment of the organizational activity towards the strategic intent of the organizational sustainability philosophy in the business ecology. It also helps in equipping the organization to achieve the operational excellence and the strategic business growth at the same time.

Current study is unique in its attempt to understand the capability of proposed sustainability dimensions to capture the sustainability practices followed across different industrial sectors.

The purpose of this paper is to make economic comparison of the proposed X¯ chart with the economic and economic‐statistical design of a multivariate exponentially weighted moving average (MEWMA) control chart proposed by Linderman and Love, using Lorenzen‐Vance cost model.

The economic design of proposed X¯ chart, using Lorenzen‐Vance cost model, is discussed in the paper. It is observed that sampling interval (h) and expected cost/hour (C) depend on various parameters of the chart, used in this model. When there is any change in any parameter of the chart, obviously both sampling interval and expected cost will be different. So it is suggested that one should use Lorenzen and Vance cost model (equation 1) to compute sampling interval and expected cost/hour for the proposed X¯ chart.

The economic design of the proposed X¯ chart has been compared with the economic and economic‐statistical design of the multivariate exponentially weighted moving average (MEWMA) control chart proposed by Linderman and Love. It is found that the proposed X¯ chart performs better than MEWMA chart proposed by Linderman and Love for sample sizes of 7, 9 and 10 for first set of parameters. The proposed X¯ chart also shows lower expected cost/hour than the MEWMA chart for sample size of 2 and 3 and for shifts of 2 and 3 for the second set of parameters.

A lot of effort has been made to develop the proposed X¯ chart for monitoring the process mean. Although optimal sampling intervals are calculated only for two sets of parameters for shifts in the process average of 1, 2 and 3, it can be computed for any set of parameters using the Lorenzen‐Vance cost model.

The research findings could be applied to various manufacturing and service industries, as it is more effective than the Shewhart and EWMA charts.

The purpose of this paper is to present a methodological framework and practical application of the sustainable development assessment in Lithuania.

The assessment was performed by deriving composite economic, social and environmental indexes and combining them into the integrated sustainable development index. Each composite index aggregates number of selected indicators, which were essential for the assessment of the country's development during the last decade. Having in mind that sustainable development is the development in consistency, the authors have used equal weights for calculation of economic, social and environmental indexes.

The composite indexes indicate rapid economical growth and environmental state; however, social development was comparatively slow. The economical decline in 2008 has influenced also environmental and social development and revealed new trends of sustainable development in Lithuania. The analysis results demonstrate that goals brought forward in the Strategy for Sustainable Development of Lithuania were not achieved.

The paper provides a methodology of integrated sustainable development index and its application for the Lithuanian case. The greatest advantage of a proposed calculation methodology is its flexibility, because it can be applied for any period of sustainable development evaluation, with a possibility to select a desired number of sustainability aspects that reflect an evolution of a country the best.

Cities throughout the world have experienced fundamental social, cultural and economic transformation in recent decades. Socio-cultural and urban identities have been transforming radically; globalization, internationalization and the rapid flow of information, as the case in the rest of the world, have played a significant role in changing cities and their people. These changing dynamics have affected continuity and development trends in urban-housing environments and housing preferences. The multidimensional outcomes of this transformation are manifest in peculiarities of activity patterns, behavioral relationships, and socio-cultural norms, as well as in architectural and urban configurations. These rapid economic and social changes demand continual redefinition of urbanization and housing concerns. Therefore, the main aim of the article that based on ongoing research is to examine implications of urban and architectural transformations in Istanbul with the subjects of economical, cultural and political conditions.

Based on these above arguments, article aims to analyze and discuss the relationship between urban dynamics and new housing developments in Istanbul in the context of transformation process. The article, which consists of five sections, has three sections besides the introduction and conclusion. In the first two part a theoretical framework is established, explaining and discussing culture, continuity and change in the process of urbanization. The second part includes the latest housing trends in Istanbul with the subjects of economical, cultural and political conditions that Turkey is already in and related. The third part examines the emerging patterns of social and cultural differentiation in Istanbul through the examples of the exclusive suburbs At the end, we argue that recent housing projects and trends represent new forms of organizing social and cultural differences, and could be read as urban forms, which create segregation and reproduce inequalities while transforming the character of public life.

The present paper is aimed at arguing the fallacy of those political arguments when an economical evaluation of those advantages is implicated. The present analysis will unearth the partisan nature of the specific accounting rules and principles to fill up the Italian financial reporting in spite of any environmental sensitivity. The paper attempts to suggest a mediation through a comprehensive view on hegemonic discourses of environmental management and their counter‐evidences of accounting practices about environmental management.

The discussion is pivoted on the counter‐evidences of the present management tools both at the level of financial reporting and analytical accounting.

The evidences stress the limits of the accounting regulation, since the categories of costs in the financial report scheme open a few possibilities to distinguish the environmental costs. Those considerations are an obstacle to the “internalization” of environmental externalities and they do not support the main issue of a pro‐active environmental system.

The present work shows the potential of accounting to make things visible and measurable and the will to take this opportunity to solve the urgency of the environmental problems. In so doing, the work contributes to the present debate on environmental management systems, through a detailed and in‐depth analysis of the accounting loci for environmental issues.

The purpose of this paper is to present a framework for examining the outcome of value facilitation as the added value of service provision.

Value facilitation is conceptualized as enabling, enhancing, and economical support by the service offering, as well as supportiveness by the service provider. The financial value of customers is measured by the augmented customer lifetime value (ACLV).

Referrals is found to mediate the linkage between value facilitation and ACLV. The margin multiple level and corresponding propensity to stay scores are found to be better proxies for setting up a customer oriented service development program, than the customer profit or margin level.

This paper takes a service provider perspective on service, even though the customer experience of the service provision is vital.

The proposed framework can be used for designing adapted customer strategies for different groups of customers representing different levels of added value of the service provision.

This paper extends the normative service logic notion of the role of service providers as value facilitators and supporters of their customers’ value creation activities. The calculation of ACLV is altered from ordinary customer lifetime value models by the integration of individual transaction data and propensity to stay figures from a customer survey.
