Abstract

Purpose

This paper aims to review national aeronautics and space administration (NASA’s) broad investments in electrified aircraft propulsion (EAP). NASA investments are guided by an assessment of potential market impacts, technical key performance parameters, and technology readiness attained through a combination of studies, enabling fundamental research and flight research.

Design/methodology/approach

The impact of EAP varies by market and NASA is considering three markets as follows: national/international, on-demand mobility and short-haul regional air transport. Technical advances in key areas have been made that indicate EAP is a viable technology. Flight research is underway to demonstrate integrated solutions and inform standards and certification processes.

Findings

A key finding is that sufficient technical advances in key areas have been made, which indicate EAP is a viable technology for aircraft. Significant progress has been made to reduce EAP adoption barriers and further work is needed to transition the technology to a commercial product and improve the technology, so it is applicable to large transonic aircraft.

Practical implications

Significant progress has been made to reduce EAP adoption barriers and further work is needed to transition the technology to a commercial product and improve the technology, so it is applicable to large transonic aircraft.

Originality/value

This paper will review the activities of the hybrid gas-electric subproject of the Advanced Air Transport Technology Project, the Revolutionary Vertical Lift Technology Project and the X-57 Flight Demonstration Project, and discuss the potential EAP benefits for commercial and military applications. This paper focuses on the vehicle-related activities, however, there are related NASA activities in air space management and vehicle autonomy activities, as well as a breakthrough technology project called the Convergent Aeronautics Solutions Project. The target audience is people interested in EAP.

Abstract

Purpose

The purpose of this study is to learn what factors liaison librarians in academic research libraries consider in determining whether to refer chat reference patrons to subject specialists.

Design/methodology/approach

Subject specialists were asked what policies guided their decisions to refer to a specialist and then assessed unreferred chat session transcripts both within and outside their specializations to determine need for a referral.

Findings

Few respondents were guided by formal policies. Contrary to an initial hypothesis, subject area was not a key factor in referring chat. A broader set of criteria included reference interviewing, provision of relevant resources and information literacy instruction. Respondents valued both the depth that subject specialists can provide to reference interactions and the ability of a skilled generalist to support information literacy.

Research limitations/implications

Findings are most applicable to large, public doctoral universities with liaison librarian programs. Assignment of respondents to subject specialist categories was complicated by their broad range of background and expertise.

Practical implications

The study contributes new understanding of referrals to subject specialists who have potential to guide development of formal referral policies in academic library virtual reference services.

Originality/value

The study is the first empirical examination of chat reference referral decisions.

Abstract

Purpose

This analysis of chat reference transcripts assesses differences in how librarians and graduate assistants (GAs) incorporate teaching strategies in responding to chat reference inquiries in social sciences, health sciences, humanities, STEM and business/economics at a large, public R1 university in the United States.

Design/methodology/approach

Researchers with disciplinary assignments in five different subject domains conducted qualitative analysis of a purposive sample of 982 transcripts of chat interactions during four semesters in 2021 and 2022.

Findings

Some form of information literacy instruction (ILI) occurred in 58% of the transcripts, with slightly less teaching occurring in social sciences inquiries than in other subject areas. Of transcripts that included teaching strategies, search procedures predominated, followed by a mix of concepts and procedures, and the least with concepts only. Chat providers taught concepts specific to social sciences, health sciences and humanities, but not to STEM or business.

Research limitations/implications

The study compares transcripts at one institution; findings may be most applicable to large, research institutions that seek to incorporate ILI in online reference services.

Practical implications

Chat reference training should include best practices for ILI relevant to specific subject domains for providers without background in those disciplines and recommendations for referrals to subject specialists.

Originality/value

Existing ILI literature does not address the question of how chat providers teach concepts rooted in a specific subject domain or offer a comparison of teaching strategies employed in different disciplines, by librarians versus GAs or staff.

Abstract

This chapter is designed with the aim to determine the influence of sociodemographic variables on the capacity to generate social enterprises, such as sex, the student’s country, if only they study or if they study and work, as well as if they participate or direct a social enterprise in university students of Latin American business schools. This research adopted an inductive quantitative approach using a questionnaire. The participants were university students of business schools from Colombia, Mexico and Peru. Second-generation structural equation method (SEM-PLS) was used to analyse the results, using the SmartPLS 3.2.7 software applied to data on 3,739 university students. The results suggest that the entrepreneur role, labour situation, country and sex have a moderating effect in the relation between entrepreneurial orientation and entrepreneurial intention. Also, by using resampling technique Bootstrapping (5,000 times,p < 0.01), significance of the trajectory coefficients (beta) and effect size of the coefficients (beta) were measured to demonstrate significance. Finally, with this research the authors ascertain that entrepreneurial orientation positively influences entrepreneurial intention. thus explaining 42.4% of its variance. This chapter is the first attempt on investigating in university students of Latin American business schools about factors of entrepreneurship orientation and entrepreneurship intention, and has strong potential to contribute to development of policies and strategies to promote the growth of entrepreneurship activities in the universities.

Abstract

What began as peer training instruction sessions for DePaul University librarians has grown into an electronic knowledge base available 24 × 7 for ongoing staff development. Using Blackboard course management software, DePaul University Libraries developed peer to peer instruction to keep communication open among staff members at all eight campus libraries while sharing subject expertise among librarians and sharpening skills needed in group and one‐on‐one instruction. In order to facilitate continued communication between librarians at different campuses at DePaul University, an annual program of structured peer training sessions was developed and implemented within the last two years to provide ongoing professional development.

Abstract

Purpose

Construction sustainability (CS) is a strategic reaction to the sustainability expectations of the construction industry's external stakeholders. The extant literature has viewed the environmental, social and economic dimensions of CS as having independent effects on financial performance. Due to the influence of common stakeholders, however, interactions in these dimensions will be present in their effect on financial performance. Accordingly, this study identifies the mechanisms of the interactions between the three CS dimensions and how they jointly affect financial performance.

Design/methodology/approach

Content analysis of GRI reports of 60 large construction organisations, followed by a hierarchical regression analysis was used to identify the interactions between environmental, social and economic CS in their effect on financial performance.

Findings

Economic CS was found to indirectly, and not directly, affect financial performance, the effect being mediated by both environmental and social CS. Environmental CS was found to have a strong negative effect on financial performance, whilst social CS was found to have a strongly significant positive effect on financial performance.

Practical implications

The motivation for engaging in CS is that investment in economic CS will have a positive effect on both environmental and social CS outcomes, which, in turn can have a combined effect on financial performance.

Originality/value

This is one of the first studies investigating the effect of interactions between the environmental, social and economic CS dimensions on the financial performance of construction organisations. It is also one of the first studies that applies a sociotechnical framework to this relationship.

Abstract

This study uses a microanalysis of interaction approach to study how interactive service workers collaborate with one another in conversations to construct their professional identity in the face of the rapid contextual change. The data consist of (1) a complex written exchange downloaded from an Internet listserv and (2) a mechanically recorded conversation and detailed transcript showing the exact sequence of turns in the conversation, overlapping utterances, laughter, and speech errors. Everyday descriptions in these conversations reveal how knowledge workers produce and reproduce professional identity and a shared culture in the ways they: (1) categorize themselves and other workers, (2) amend or collaborate on each other's characterizations of clients, and (3) negotiate local policies and rules as they intersect with professional values and emotional boundaries. The results demonstrate a need for opportunities to integrate the increasing complexity of interactive service into professional identity as a response to technological and social change.

Abstract

Higher education, and in particular libraries, have changed significantly over the last decade due to the adoption of technological advancements such as the Internet and the World Wide Web. The multitude of ways patrons can interact with librarians and library resources has been only the latest step in a very long process which started with traditional snail mail and the phone. As educators, librarians have always been interested in using new tools to improve services. These services are increasingly being made available to patrons who do not physically enter a library building. This paper looks at what library services are currently being offered to students at a distance in order to better plan for the future.
