This study aims to explore the viability of using C-17 reduced-engine taxi procedures from a cost savings and capability perspective.
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
This paper aims to explore the potential explanatory mechanisms linking leader–member exchange (LMX) and a perceived supportive environment for corporate entrepreneurship. Specifically, this paper develops and tests a hypothesized moderated mediation model of the relationship between LMX and a perceived supportive environment for corporate entrepreneurship through psychological empowerment as conditional upon the level of control orientation.
Design/methodology/approach
Data were collected from a sample of 682 full-time working adults in the USA and were examined in a moderated mediation model in PROCESS.
Findings
The findings suggest that higher LMX augments perceptions of a supportive environment for corporate entrepreneurship with a mediating role for psychological empowerment and a moderating role for control orientation on that conditional relationship.
Research limitations/implications
This research suggests that high quality LMX relationships may enrich the human capital of firms, helping them to innovate and outperform competitors in the context of modern competitive dynamics. The study findings are limited by several factors including a cross-sectional design and a student-recruited sampling approach.
Originality/value
The study offers unique contributions to the leadership and entrepreneurship literature by being among the first to empirically investigate the relationship between LMX and a perceived supportive environment for corporate entrepreneurship as mediated by psychological empowerment and moderated by control orientation, yielding important insights regarding effective leadership practices for facilitating innovative behaviors and corporate entrepreneurship.

Abstract
Purpose
The purpose of the study is to highlight the need for academic librarians to incorporate effective methodologies in their delivery of information literacy instruction.
Design/methodology/approach
The researchers conducted a qualitative research using a case study approach. A nonprobability or purposive sampling method was employed in this research to select five participants. Semistructured interviews and observation were used to garner data from the sample.
Findings
The findings of the study revealed that the support required by distance education and face-to-face students is typically the same. An examination of the findings pointed to the fact that some students may be demotivated in information literacy instruction sessions because of an overload of information, which leads to frustration and poor performance.
Practical implications
The findings of the study highlight the need for Caribbean academic librarians to incorporate effective methodologies in their delivery of information literacy instruction and provide an analytical view of how these methodologies may impact performance, understanding and the overall work produced by both students and faculty.
Originality/value
Research on the topic specific to the Caribbean is limited; therefore, research of this nature provides useful strategies that academic librarians may use in developing stellar information literacy programs in the Caribbean to help both students and faculty members achieve excellence.

Abstract
Researchers have found many career and technical education administrators are not fully prepared for the unique challenges found in the administrative domain of career and technical education (CTE). Tools for identifying specific needs of CTE administrators are lacking, thus prompting the development of the CTE Administrator Self- Efficacy (CASES) survey instrument. The CASES survey instrument can identify professional development and instructional training necessary for enhancing the CTE administrator’s leadership and management abilities. CTE administrators will benefit from the CASES self-assessment by identifying their strengths and weaknesses. CASES will affect change within the field of CTE, as it will set the stage for training and professional development needed to assure the success of CTE administrators as sound leaders of their school communities.

This study aims to assess service quality in sport child camps among both participants and parents and its effects on satisfaction and behavioural intentions.
Abstract
Purpose
This study aims to assess service quality in sport child camps among both participants and parents and its effects on satisfaction and behavioural intentions.
Design/methodology/approach
Data were collected from participants (n = 258) and parents (n = 226) of a sport child camp. A confirmatory factor analysis analysed the psychometric properties of the constructs, and a subsequent structural equation model examined the effects of service quality on satisfaction and behavioural intentions.
Findings
The results indicate a multi-dimensional construct of service quality that influences satisfaction and behavioural intentions differently among parents and participants. For participants, Service Failures and Recovery, Safety and Food influenced satisfaction, while Service Failures and Recovery and Fun influenced Behavioural Intentions. For parents, Management Commitment to Service Quality, Staff, Food and Contact with Physical Environmental influenced satisfaction, while Management Commitment to Service Quality and Staff influenced Behavioural intentions.
Research limitations/implications
Both parents and participants' perceptions of service quality in sport child camps were captured and its effects on satisfaction and behavioural intentions. The study provides sport child camp managers with critical information about service delivery and its outcomes among the two key consumers (participants and parents).
Originality/value
This study offers new ideas to advance knowledge on sport child camps by capturing the perceptions of two key stakeholders and providing useful insights into how different attributes of service quality influence the levels of satisfaction and behavioural intentions among parents and participants.
