The traditional predictor of technical inefficiency proposed by Jondrow, Lovell, Materov, and Schmidt (1982) is a conditional expectation. This chapter explores whether, and by how much, the predictor can be improved by using auxiliary information in the conditioning set. It considers two types of stochastic frontier models. The first type is a panel data model where composed errors from past and future time periods contain information about contemporaneous technical inefficiency. The second type is when the stochastic frontier model is augmented by input ratio equations in which allocative inefficiency is correlated with technical inefficiency. Compared to the standard kernel-smoothing estimator, a newer estimator based on a local linear random forest helps mitigate the curse of dimensionality when the conditioning set is large. Besides numerous simulations, there is an illustrative empirical example.

This study examined the factors influencing willingness-to-repurchase for each class of airline service, and integrate the constructs of service quality, satisfaction and willingness-to-repurchase which were rooted on Engel-Kollat-Blackwell (EKB) model. The study focuses on the domestic and international arrival of passengers at Murtala Muhammed International Airport in Lagos and Nnamdi Azikwe International Airport in Abuja. Information was gathered from domestic and foreign passengers who had post-purchase experience and had used the airline's services more than once. The survey data were obtained concurrently from arrival passengers at two major international airports using an electronic questionnaire through random and purposive sampling techniques. The data was analysed using the ordinal logit model and structural equation model. From the 606 respondents, 524 responses were received but 489 responses were valid for data analysis and reporting and were obtained mostly from economy and business class passengers. The study found that the quality of seat pitch, allowance of 30 kg luggage permission, availability of online check-in 24 hours before the departing flight, quality of space for legroom between seats, and the quality of seats that can be converted into a fully flatbed are the major service factors influencing willingness-to-repurchase economy and business class tickets. Also, it was found that passengers' willingness to repurchase is influenced majorly by service quality, but not necessarily influenced by satisfaction. These results reflect the passengers' consciousness of COVID-19 because the study was conducted during the heat of COVID-19 pandemic. Recommendations were suggested for airline management based on each class.

Collegiality is the modus operandi of universities. Collegiality is central to academic freedom and scientific quality. In this way, collegiality also contributes to the good functioning of universities’ contribution to society and democracy. In this concluding paper of the special issue on collegiality, we summarize the main findings and takeaways from our collective studies. We summarize the main challenges and contestations to collegiality and to universities, but also document lines of resistance, activation, and maintenance. We depict varieties of collegiality and conclude by emphasizing that future research needs to be based on an appreciation of this variation. We argue that it is essential to incorporate such a variation-sensitive perspective into discussions on academic freedom and scientific quality and highlight themes surfaced by the different studies that remain under-explored in extant literature: institutional trust, field-level studies of collegiality, and collegiality and communication. Finally, we offer some remarks on methodological and theoretical implications of this research and conclude by summarizing our research agenda in a list of themes.

This chapter focuses on two aspects of the achievement gap – underachievement and low achievement among Black males in urban school contexts. More specifically, the authors explain several problems/issues confronting Black male students in P-12 gifted and talented, advanced placement, and special education programs, along with the school-to-prison pipeline – inequitable discipline in the form of suspensions and expulsions. We parse underrepresentation and overrepresentation for this student group. A central part of this discussion is grounded in the achievement gap literature on Black students in general with implications for Black males in particular. Another fundamental aspect of this discussion is the need for educators to adopt an anti-racist (social justice or civil rights) and cultural competence approach to their work, which means being equity-based and culturally responsive in philosophy and action. Suggestions for closing the achievement gap and otherwise improving the achievement of Black males are provided for educators. We also compel educators to go beyond talking about equity by setting quantifiable equity goals for minimum and maximum percentages (and numbers).

What are the academic experiences of senior professors in the field of public relations (PR) at the Brazilian universities? This chapter proposes the advance of knowledge on the theoretical framework of contemporary liberal feminism by refining the previous theoretical and methodological publications. This theoretical lens prevails in earlier works, with empirical studies grounded in industry and corporate environments – mainly done by researchers from the United Kingdom, North America and Scandinavia, while PR feminist postmodernism appears in European literature – all scarce in Brazil and Global South (Latin America and African nations). Moreover, studies applying female or male PR scholars in university settings are rare in national and international literature. Hence, we gathered data and analysed narratives from seven senior female PR professors from Brazil, using an interpretative qualitative approach. Thus, this chapter about the female PR academic experiences and everyday practices highlights the starting point for an onto-epistemological discussion to understand the liberal feminist educational-based context in a Latin American country. Henceforth, two conceptual-practical dimensions – feminist PR competence and feminist PR performance – along with three methodological recommendations are presented for enhancing the contemporary liberal feminism theme as a robust research domain in PR and Strategic Communication agenda.

Warren Nutter and James M. Buchanan did not revise “Universal Education” to turn against providing tuition grants to segregated schools in 1965. Their revised text contains no call to expel segregation academies from the tuition grant program and does not even express disapproval of the goals or the work of segregation academies. Recent claims to that effect by Fleury (2023) and Levy and Peart (2023) cannot be sustained by either textual or contextual evidence.

The author examines the experiences of learning about Japanese elementary education from the perspective of a Canadian teacher. She suggests through a year-long study in a Japanese third grade classroom that the teaching practices and philosophies underlying curricular and pedagogical decisions made by teachers are shaped by the culture and society of which schools are part, such that learning about Japanese schooling highlights the influence of social, societal, cultural, linguistic factors outside, as well as inside, school. In line with narrative inquiry research practices, the author also acknowledges her own stance as a certified elementary level teacher who was educated and certified in Canada, in contributing to shaping her analysis of teacher knowledge of her teacher participants. She argues that the process of learning about schooling in a country or culture different from the one in which an individual was educated and learned to teach, involves immersing oneself into the research context to learn about the experience from the perspective an insider. Realization of the extent to which this expansive interweaving of school and society is apparent in many aspects of schooling in Japan, in turn, reinforces the idea that this interconnection may also underlie schooling in other societies as well, such that one's experiences in one's own culture may form the foundation for understanding and interpreting knowledge gained about schooling in another culture or community. The notion of cross-cultural teacher knowledge, then, may be grounded in personal and professional experience of teaching and being taught in one's own culture.
