Abstract

Purpose

Temperature anomalies in the upper troposphere have become a reality as a result of global warming, which has a noticeable impact on aircraft performance. The purpose of this study is to investigate the total air temperature (TAT) anomaly observed during the cruise level and its impact on engine parameter variations.

Design/methodology/approach

Empirical methodology is used in this study, and it is based on measurements and observations of anomalous phenomena on the tropopause. The primary data were taken from the Boeing 747-8F's enhanced flight data recorder, which refers to the quantitative method, while the qualitative method is based on a literature review and interviews. The GEnx Integrated Vehicle Health Management system was used for the study's evaluation of engine performance to support the complete range of operational priorities throughout the entire engine lifecycle.

Findings

The study's findings indicate that TAT and SAT anomalies, which occur between 270- and 320-feet flight level, have a substantial impact on aircraft performance at cruise altitude and, as a result, on engine parameters, specifically an increase in fuel consumption and engine exhaust gas temperature values. The TAT and Ram Rise anomalies were the focus of the atmospheric deviations, which were assessed as major departures from the International Civil Aviation Organizations–defined International Standard Atmosphere, which is obvious on a positive tendency and so goes against the norms.

Research limitations/implications

Necessary fixed flight parameters gathered from the aircraft's enhanced airborne flight recorder (EAFR) via Aeronautical Radio Incorporated (ARINC) 664 Part 7 at a certain velocity and altitude interfacing with the diagnostic program direct parameter display (DPD), allow for analysis of aircraft performance in a real-time frame. Thus, processed data transmits to the ground maintenance infrastructure for future evaluation and for proper maintenance solutions.

Originality/value

A real-time analysis of aircraft performance is possible using the diagnostic program DPD in conjunction with necessary fixed flight parameters obtained from the aircraft's EAFR via ARINC 664 Part 7 at a specific speed and altitude. Thus, processed data is transmitted to the ground infrastructure for maintenance to be evaluated in the future and to find the best maintenance fixes.

Abstract

Purpose

This paper explores a five-year case example of two educators engaged in practice-based professional development (PBPD) for the Self-Regulated Strategy Development (SRSD) model in a middle school. It examines the transformative effects and challenges of improving writing instruction, the activities involved and alternative PBPD delivery methods. Highlighting a collaborative effort between an institute of higher education (IHE), a middle school and ThinkSRSD, a PBPD for SRSD developer, the example underscores the long-term benefits and innovative insights into engaging with PBPD for SRSD over multiple years.

Design/methodology/approach

The case involves analyzing survey data collected over five years. These surveys, which included specific SRSD-related queries and open-ended questions, were instrumental in assessing the evolution of the educators’ perceptions regarding SRSD and their engagement with PBPD. Additionally, the paper details PBPD activities as documented in a research journal, providing a comprehensive account of the developmental process.

Findings

Through a cross-institutional partnership, two middle school general educators participated in PBPD for SRSD for 30 h across five years. Their engagement with PBPD progressed from initial introduction and implementation to facilitating PBPD for SRSD among peers and at the national level. Over time, the most consistently enacted SRSD action was “memorize it,” while actions such as “discuss it,” “support it” and “independent performance” showed greater variability. Both educators consistently praised SRSD and sought continued PBPD engagement over the five years.

Originality/value

Our case example is the first five-year analysis of PBPD for SRSD among general middle school educators, highlighting the benefits and challenges of adopting evidence-based writing instruction. Our example emphasizes the need for continuous and focused professional development in areas crucial for student success, including self-regulation, prewriting strategies and techniques for fostering independent performance. Moreover, the two middle school educators’ critical feedback is invaluable for refining PBPD for SRSD. This work also enriches professional development schools (PDS) literature by offering effective strategies to support middle school teachers in developing a vibrant writing community, a cornerstone for student advancement in writing.

Abstract

Purpose

The purpose of this study was to examine the boundary conditions of Kanter's (1977) tokenism theory as applied to the gender wage gap. The authors aimed to discover if there was a point where the relationship between the percentage of women in a job category and the gender wage gap changed, and, if so, where the threshold was located and what was the nature of the shift in relationship.

Design/methodology/approach

The authors used the Andrews’ (1993) threshold effects technique. Using 22 separate years of publicly available Canadian wage data, they examined the relationship between the percentage of females in 40 unique occupational categories and the female-to-male earnings ratio (for a total of 880 observations).

Findings

The results showed the existence of a threshold point, and that early gains in percent female within an occupation, up to approximately 14% female in the occupation, associate with strong gains in the female-to-male wage ratio. However, beyond that point, further gains in percent female associate with smaller improvements in the female-to-male wage ratio.

Practical implications

The findings are useful in understanding the dynamics of occupational group gender composition, potential theoretical reasons for the nuances in relationship, as well as opportunities that may facilitate more equitable outcomes.

Originality/value

The results show that, though improvements were made above and below the threshold point, enhancements in the wage gap are actually larger when there are less women in the job category (e.g. tokens).

Abstract

Purpose

This paper analyses the factors that make fashion-product crowdfunding campaigns successful. The authors argue that crowdfunding is an innovative and functional way of bringing new fashion items to the market. The purpose of this paper is to answer the question whether product innovation, lifecycle and sustainability have a positive effect on the success of fashion crowdfunding campaigns. The findings highlight that the success of the fashion crowdfunding campaigns depends on creators' adherence to the values of the platform which they use to raise capital.

Design/methodology/approach

A total of 300 fashion crowdfunding projects running between the 17th of October and the 15th of December 2017 were collected from Kickstarter – the world's largest crowdfunding platform based on reward-based all-or-nothing model. Two-step binomial logistic regression was used to analyse the data.

Findings

The model predicted a significant increase in the odds of success for the fashion items crowdfunded during the first-time production, and innovative and environmentally sustainable products with a higher price range of rewards. In line with previous literature, regression analyses predicted a significant effect of the control variables of goal amount (negative) and the number of rewards (positive). Contrary to previous studies, neither the presence of a video nor the campaign length predicted success.

Originality/value

The novel findings of this study contribute to the literature by providing an analysis of success factors of fashion items on crowdfunding platforms. The results show that innovative, environmentally sustainable and higher-priced products produced by early-stage ventures are better welcomed by the audiences.

Abstract

Purpose

Using Pakistan's public sector higher education institutions as the study site, this study aims to empirically substantiate, under the theoretical underpinnings of job enrichment theory (Hackman and Oldham, 1976) and Maslow's (1943) theory of the hierarchy of needs, the impact of flexible work practices (FWPs), on employee work engagement and organizational attractiveness, with the mediating lens of work life enrichment.

Design/methodology/approach

Field data were collected at five higher education institutions located in the Islamabad Capital Territory (ICT) of Pakistan, using the convenience sampling technique and analyzed under the quantitative research paradigm.

Findings

This study substantiates with an empirical evidence that flexible work practices (FWPs) have a significant positive impact on both employee work engagement and organizational attractiveness. Markedly, the study findings reveal that the said impact is significantly stronger than that of sabbaticals. Furthermore, the study reveals that the positive relationship is mediated by work life enrichment, signaling its significance in understanding FWP's such impact on employee work engagement and organizational attractiveness.

Practical implications

The study findings provide significant implications for academia, practitioners, and policymakers, in evidence-based recommendations for higher education institutions to design and implement FWPs that are effective in enhancing employee work engagement and organizational attractiveness, and, in turn, leading to improved organizational performance.

Originality/value

This research study provides a novel contribution to the existing literature by exploring the combined impact of flexible work practices on employee work engagement and organizational attractiveness in the peculiar context of Pakistan's public sector higher education institutions. Additionally, the study's focus on the mediating role of work life enrichment further adds to its novelty.

Abstract

Purpose

This study aims to ascertain the personal characteristics of a group of successful academic entrepreneurs in a South African university enterprise and the prevalent barriers and enablers to their entrepreneurial endeavour.

Design/methodology/approach

The authors used a Delphi process to identify and rank the characteristics, enablers, barriers and behaviours of entrepreneurial academics, with a Nominal Group Technique applied to establish challenges they encounter managing their enterprise and to propose solutions.

Findings

Perseverance, resilience and innovation are critical personal characteristics, while collaborative networks, efficient research infrastructure and established research competence are essential for success. The university’s support for entrepreneurship is a significant enabler, with unnecessary bureaucracy and poor access to project and general enterprise funding an impediment. Successful academic entrepreneurs have strong leadership, and effective management and communication skills.

Research limitations/implications

The main limitation is the small study participant group drawn from a single university enterprise, which complicates generalisability. The study supported the use of Krueger’s (2009) entrepreneurial intentions model for low- and middle-income country (LMIC) academic entrepreneur investigation but proposed the inclusion of mitigators to entrepreneurial activation to recognise contextual deficiencies and challenges.

Practical implications

Skills-deficient LMIC universities should extensively and directly support their entrepreneurial academics to overcome their contextual deficiencies and challenging environment.

Originality/value

This study contributes to addressing the paucity of academic entrepreneur research in LMIC contexts by identifying LMIC-specific factors that inhibit the entrepreneur’s movement from entrepreneurial intention to entrepreneurial action.

Abstract

Purpose

Despite the longstanding male dominance in the socio-politico-economic spheres, recent decades have witnessed remarkable improvements in gender inclusion. Although the issue of gender inclusion has been widely documented, answers to the question of whether institutional arrangements and information technology shape gender inclusion remain contentious. This study, therefore, empirically examines the effects of institutional quality and ICT penetration on gender inclusion on a global scale.

Design/methodology/approach

To control for the endogeneity of modeled variables and cross-sectional dependence inherent with large panel datasets, the study employs the Driscoll-Kraay Fixed Effects (DKFE) and the system Generalised Method of Moments (GMM) estimators for a panel of 142 countries from 1996 to 2020.

Findings

The empirical findings from the DKFE and system GMM estimators reveal that strong institutions significantly enhance gender inclusion. Moreover, by disaggregating institutional quality into various governance indicators, we show that besides corruption control, which has a positive but insignificant effect on women’s empowerment, other governance indicators significantly enhance gender inclusion. Furthermore, there is evidence that various ICT measures promote gender inclusion.

Practical implications

The study results suggest that policymakers in developing countries should implement stringent measures to curb corruption. Moreover, policymakers in low-income countries should create avenues to facilitate women’s access to ICTs. Hence, policymakers in low-income countries should create and equip ICT training centers and render them accessible to all categories of women. Furthermore, developed countries with high-tech knowledge could help developing countries by organizing free training workshops and sensitization campaigns concerning the use of ICTs vis-à-vis women empowerment in various fields of life.

Originality/value

The present study fills a significant research gap by comprehensively exploring the nexuses between governance, ICT penetration, and the socio-politico-economic dimensions of gender inclusion from a global perspective. Besides the paucity of studies in this regard, the few existing studies have either been focused on region and country-specific case studies in developed or developing economies. Moreover, this study is timely, given the importance placed on gender inclusion (SDG5), quality of institutions (SDG16), and ICT penetration (SDG9) in the 2015–2030 global development agenda.

Abstract

Purpose

Coal is a critical global energy source, and fluctuations in its price significantly impact related enterprises' profitability. This study aims to develop a robust model for predicting the coal price index to enhance coal purchase strategies for coal-consuming enterprises and provide crucial information for global carbon emission reduction.

Design/methodology/approach

The proposed coal price forecasting system combines data decomposition, semi-supervised feature engineering, ensemble learning and deep learning. It addresses the challenge of merging low-resolution and high-resolution data by adaptively combining both types of data and filling in missing gaps through interpolation for internal missing data and self-supervision for initiate/terminal missing data. The system employs self-supervised learning to complete the filling of complex missing data.

Findings

The ensemble model, which combines long short-term memory, XGBoost and support vector regression, demonstrated the best prediction performance among the tested models. It exhibited superior accuracy and stability across multiple indices in two datasets, namely the Bohai-Rim steam-coal price index and coal daily settlement price.

Originality/value

The proposed coal price forecasting system stands out as it integrates data decomposition, semi-supervised feature engineering, ensemble learning and deep learning. Moreover, the system pioneers the use of self-supervised learning for filling in complex missing data, contributing to its originality and effectiveness.

This study aims to deepen our understanding of how inclusionary practices are used within organizations and how they satisfy specific inclusion needs.

Abstract

Purpose

This study aims to deepen our understanding of how inclusionary practices are used within organizations and how they satisfy specific inclusion needs.

Design/methodology/approach

We adopt a qualitative research design, reporting on data from semi-structured interviews conducted with 15 diversity and inclusion (D&I) directors/leads and using a thematic approach to analysis.

Findings

Our study expands understanding of inclusion practices, showing that they are not uniformly implemented and that practices may satisfy both needs to belong and differences valued, with interviewees prioritizing belonging. Well-being and career development are seen as important inclusion practices demonstrating support and appreciation of difference, thus as inputs, not outputs, of inclusion challenging existing assumptions. Inclusionary practices are malleable, and their impact depends critically on the leaders involved and their commitment to EDI.

Originality/value

Our study shows how practices satisfy inclusion needs and that the implementation of practices varies depending on the leaders involved.

The purpose of this paper is to analyze the prejudice and discrimination constructs through the lens of a transcendent knowledge concept.

Abstract

Purpose

The purpose of this paper is to analyze the prejudice and discrimination constructs through the lens of a transcendent knowledge concept.

Design/methodology/approach

The paper seeks to demonstrate that Spiritism or Spiritist Doctrine (SD) – regarded here as a source of transcendent knowledge – offers compelling arguments and provides suitable explanations (i.e. transcendent ontology) in relation to the issue of discrimination

Findings

Overall, this paper contributes to a better understanding of diversity and inclusive perspectives by examining the antecedents and consequences of discrimination through the insightful lens of SD tenets. In this sense, the findings suggest that the discriminators and prejudiced people may ironically pass through – as a result of the law of cause and effect – the same hard situations (i.e. ordeals or nightmares) – even though in their future lives – that they impose in their current victims to forcefully open their minds, support universal values, enhance their own feelings and spiritual intelligence.

Practical implications

Evidence presented here (although conceptually in nature) could be somewhat integrated into training sections of diversity management. At a minimum, it may encourage the shift of attitudes, revision of embedded values and reflections about the spiritual consequences to the perpetrators of discrimination against minorities.

Originality/value

Taken as a whole, the SD tenets prompt us to understand that the acts of prejudice, stereotyping and discrimination engender suffering for their perpetrators, even in their future lives (i.e. reincarnations). Broadly speaking, the SD principles compel us to consider transcendent knowledge even in the context of organizational life.
