Abstract

Purpose

This study aims to explore the viability of using C-17 reduced-engine taxi procedures from a cost savings and capability perspective.

Design/methodology/approach

This study model expected engine fuel flow based on the number of operational engines, aircraft gross weight (GW) and average aircraft groundspeed. Using this model, the research executes a cost savings simulation estimating the expected annual savings produced by the proposed taxi methodology. Operational and safety risks are also considered.

Findings

The results indicate that significant fuel and costs savings are available via the employment of reduced-engine taxi procedures. On an annual basis, the mobility air force has the capacity to save approximately 1.18 million gallons of jet fuel per year ($2.66m in annual fuel costs at current rates) without significant risk to operations. The two-engine taxi methodology has the ability to generate capable taxi thrust for a maximum GW C-17 with nearly zero risks.

Research limitations/implications

This research was limited to C-17 procedures and efficiency improvements specifically, although it suggests that other military aircraft could benefit from these findings as is evident in the commercial airline industry.

Practical implications

This research recommends coordination with the original equipment manufacturer to rework checklists and flight manuals, development of a fleet-wide training program and evaluation of future aircraft recapitalization requirements intended to exploit and maximize aircraft surface operation savings.

Originality/value

If implemented, the proposed changes would benefit the society as government resources could be spent elsewhere and the impact on the environment would be reduced. This research conducted a rigorous analysis of the suitability of implementing a civilian airline’s best practice into US Air Force operations.

Abstract

Purpose

The aim of this paper is to investigate the sediment and pollution profiling and particle size distribution with depth within permeable paving structures, both with and without a geotextile.

Design/methodology/approach

Test rigs set up in an earlier pilot study were used for four separate but linked studies. Street dust was applied to rigs C and D to determine the retention of sediments. Heavy metals together with street dust were applied to rig A and B (previously control rigs) to determine the effect of sediment on the pollution removal capabilities of the test rigs. Following the application of sediment, rigs A and B were carefully taken apart to determine pollution profiles and particle size distributions.

Findings

The findings reveal that sediment does have an effect on the metal removal capabilities of permeable paving systems, but there was minimal difference between the rigs with a geotextile and without. Pollution profiling within the test rigs identified that the greatest concentration of metals was in the surface sediment and that both rigs removed similar percentages but the concentrations of metals were distributed differently. It was also found that after between 10 and 15 years of sediment application paving rigs began to “block” causing reduced infiltration rates. Unfortunately it is difficult to explain the variations of particle size distributions found with depth in the paving structure. It had been expected to find progressively higher proportions of finer material with depth. However, the reverse was true, with a higher proportion of fines in the sediment applied to the surface and a progressive increase in the proportion of coarse material with depth

Practical implications

The conclusions confirm the effects of sediment within a permeable paving structure and indicate the loading at which the infiltration rates become affected. These results may help to determine a maintenance programme, however this would require further research.

Originality/value

The paper provides a comparative study on pollution and sediment profiling within a permeable paving structure both with and without the inclusion of an upper geotextile. It provides valuable insight into the amount of sediment on paving before it becomes blocked. The methodology and results reported in this research could be used for further studies to provide more evidence as to whether the inclusion of an upper geotextile is beneficial.

Abstract

Today, the presence of unwanted activities threatening the safety of the field, which has negative effects on daily life and social psychology, is increasing day by day. There is no doubt that it is inevitable to avoid these threats, but it is possible to take some measures to reduce the destructive power of these threats. Nowadays, increasing terrorist attacks increase the importance of field safety design in urban areas. There is a loss of life in attacks around the world. The subject of this study is to investigate the design criteria related to the built environment and the measures to be taken in the case of bomb attacks in the built environment. In this study, a checklist will designed to measure the security design process around the building. The checklist titles are taken mainly from the “Safety design and Landscape Architecture” series of the Landscape Architecture Technical Information Series/LATIS publications by the American Society of Landscape Architects (ASLA) and the Risk Management Series of the Federal Emergency Management Agency/FEMA (FEMA, 2003, 2007; LATIS, 2016) and others. The checklist created as a result of literature review will be tested in Istanbul Sultanahmet Square. As a result of the study, it was determined that improvements should be made in the areas of vehicular and pedestrian access, parking lots, lighting and trash receptacle designs around Sultanahmet Square.

Abstract

Purpose

The purpose of this study is to examine the effect of board characteristics on foreign equity ownership (FEO) in the listed public limited companies of Bangladesh.

Design/methodology/approach

The study collected data from 418 annual reports of listed companies of Bangladesh for the years 2015, 2016 and 2017 to examine the effect of board characteristics on FEO. Ordinary Least Squares (OLS) and Two-Stage Least Squares (2SLS) regression methods are used to test the hypotheses of the study.

Findings

The results show that board size has significant negative influence on FEO. Other board characteristics variables such as board independence and female directorship appear to have an insignificant influence on FEO. However, several firm characteristics variables such as return on assets, market-to-book ratio, firm size and firm age have a significant positive relationship with FEO. While presenting the regression results separately for manufacturing and non-manufacturing firms, the findings reveal a number of differences in the results between the two sectors.

Research limitations/implications

The major limitation of the study is that it concentrates only on three years annual report data in analyzing the hypothesized relationships.

Practical implications

Policy makers, regulators and top management can get meaningful insights with respect to optimal board structure and firm characteristics to attract foreign investors as the results revealed significant effects of several board and firm characteristics variables on FEO.

Originality/value

The present study includes the presence of female directors on the board to represent board characteristics. No other study has examined the relationship between FEO and female directors.

Abstract

Purpose

The purpose of this paper is to draw a portrait of training and development ideals and practices from the Islamic point of view.

Design/methodology/approach

This is a conceptual paper. The paper reviews the relevant literature on training and development from an Islamic perspective portraying the interface between ideals and practices of training and development in Islam in order to bridge a gap in the extant literature.

Findings

The literature that deals with training and development in Islam seems to belong to two major categories: essays espousing a broad perspective and including catch‐all concepts or other generic Islamic principles; and studies addressing human resource management in Islam that mainly examine training and development from a narrow perspective. The findings of this limited body of literature are far from being consistent as they seem contradictory in nature. Simultaneously, in the area of training and professional development, Islam emphasizes practical wisdom and translating theoretical insights into behaviors and practices rather than solely relying on theoretical principles.

Research limitations/implications

The literature review is not detailed due to the dearth of information on training and development from an Islamic perspective.

Practical implications

Training and learning methods from the Islamic tradition can provide constructive contribution to workplace practices as well as benefit organizations that anticipate offering efficient and effective custom‐designed training methods to best meet the training needs of their Muslim employees.

Originality/value

The present contribution is a unique synthesis of the literature related to the application of Islamic principles in training and professional development.

Abstract

Purpose

The purpose of this paper is to articulate a meaningful response to recent calls to “indigenize” and “decolonize” the Anthropocene in the social sciences and humanities; and in doing so to challenge and extend dominant conceptualisations of the Anthropocene offered to date within a posthuman and more-than-human intellectual context.

Design/methodology/approach

The paper develops a radical material and relational ontology, purposefully drawing on an indigenous knowledge framework, as it is specifically exemplified in Maori approaches to anthropogenic impacts on species and multi-species entanglements. The paper takes as its focus particular species of whales, trees and humans and their entanglements. It also draws on, critically engages with, and partially integrates posthuman and more-than-human theory addressing the Anthropocene.

Findings

The findings of this study are that we will benefit from approaching the Anthropocene from situated and specific ontologies rooted in place, which can frame multi-species encounters in novel and productive ways.

Research limitations/implications

The paper calls for a more expansive and critical version of social science in which the relations between human and more-than-human becomes much more of a central concern; but in doing so it must recognize the importance of multiple histories, knowledge systems and narratives, the marginalization of many of which can be seen as a symptom of ecological crisis. The paper also proposes adopting Zoe Todd’s suggested tools to further indigenize the Anthropocene – though there remains much more scope to do so both theoretically and methodologically.

Practical implications

The paper argues that Anthropocene narratives must incorporate deeper colonial histories and their legacies; that related research must pay greater attention to reciprocity and relatedness, as advocated by posthuman scholarship in developing methodologies and research agendas; and that non-human life should remain firmly in focus to avoid reproducing human exceptionalism.

Social implications

In societies where populations are coming to terms in different ways with living through an era of environmental breakdown, it is vital to seek out forms of knowledge and progressive collaboration that resonate with place and with which progressive science and humanities research can learn and collaborate; to highlight narratives which “give life and dimension to the strategies – oppositional, affirmative, and yes, often desperate and fractured – that emerge from those who bear the brunt of the planet’s ecological crises” (Nixon, 2011, p. 23).

Originality/value

The paper is original in approaching the specific and situated application of indigenous ontologies in some of their grounded everyday social complexity, with the potential value of opening up the Anthropocene imaginary to a more radical and ethical relational ontology.

Abstract

The end of this month will see Britain's biggest display of products and processes designed to prevent the onset of corrosion in all its forms. At the Royal Horticultural Society's New Hall, in Westminster, there will be over a hundred stands on view to visitors to the Exhibition which will run from April 27 to 30 inclusive. Here is C.T.'s exclusive preview. Stand descriptions are grouped under various headings, but the fact that a firm's exhibits are described under one heading does not necessarily mean that its interests are confined solely to that group of products. The grouping of exhibitors in this preview is merely intended to facilitate visitors who are interested in particular aspects of corrosion prevention.

Abstract

ON December 6th Mr. Salter Davies was installed President of the Library Association at Chaucer House in succession to Mr. S. A. Pitt. A word first should be said about the Presidency of Mr. Pitt. It has been carried on under handicaps that would have deterred most men in such a post. A severe illness, successfully encountered and gallantly overcome, has been the main personal feature for Mr. Pitt of what should have been the most distinguisned year of a quite eminent library career. We had looked forward to very active work from him during his Presidency, and so far as circumstances permitted, he fulfilled all the obligations laid upon him completely. We can thank him more warmly, if not more sincerely, than perhaps would ordinarily be the case, because of the difficulties he has victoriously surmounted. With newly established health, we wish for him a continuance of the great work he has done for librarianship not only in Glasgow but in the Library Association and in the world of libraries generally.
