Fundamentally, it is advantageous to operate an aeroengine's thermodynamic cycle at as high a turbine entry temperature as practical for the current metallurgical limits of the turbine blades in order to achieve peak cycle efficiency and thus lower specific fuel consumption. However, achieving the highest possible turbine entry temperature requires accurate knowledge of the turbine blade temperatures for control purposes to prolong component life as frequent excursions beyond the design limits of the blades can severely reduce their service life. The optical pyrometry technique represents the best method for providing this crucial temperature data needed for blade condition‐based monitoring. This paper presents the general operating principles, system aspects and design considerations for the application of the optical pyrometer instrument for inflight service use on gas turbine aeroengines.

This paper aims to examine whether the behavior of brands during the Great Depression held lessons for the aftermath of the coronavirus pandemic.

A review of brand marketing and advertising from the 1920s and 1930s.

There are many learnings from the Great Depression that are instructive for today’s brand marketers dealing with COVID-19.

The review of the literature is not comprehensive and the findings are subjective.

Today’s brands can learn a great deal from the 1930s such as to take advantage of opportunities and avoid mistakes in today’s difficult environment.

By handling today’s challenges skillfully, brands can refresh relationships with consumers overwhelmed with choices.

Though there was some commentary on this subject following the Great Recession of 2009, there has been little written about the lessons in brand marketing in the current situation.

The authors examine how political players attempt to rationalise arguments for and against the expansion of auditing into governmental affairs, and how state audit authorities respond to politically motivated boundary work. This study is motivated by growing evidence of political involvement in attempts to both expand and undermine state audit oversight of government affairs.

The authors present an interpreted history (covering relevant events from 1995 to 2016) of political rationales and associated boundary work that led to the expansion of the Office of the Auditor General of Ontario's (OAGO) mandate to audit government advertising campaigns for partisanship as well as attempts to modify this new audit remit over time.

The authors reveal substantive, formal and practical ways in which political players sought to rationalise/counter-rationalise expanding the OAGO's authority to the unfamiliar territory of advertising probity. The authors show how such justification claims ebb and flow in accordance with changeable political interests, and how state auditors react to the fraught nature of politically motivated boundary work.

The authors conceptualise important forms of rationalising rhetoric (which cannot be reduced to expressions of neoliberal government) that can be mobilised to deem state auditor authority legitimate in overseeing otherwise novel, unfamiliar and controversial government affairs. The authors also reveal a hitherto unrecognised resolve in state auditor responses to political intervention and shed further light on generalised forms of rationale that can underpin boundary work at the margins of accounting.

The purpose of this paper is to provide an overview of theoretical models and studies dealing with the international marketing strategies in emerging markets and provides recommendations for future research based on the review.

A review of literature on the topic was conducted and a new model is developed as a theoretical extension on the basis of insights from prior research.

Organizations need to take into account several characteristics of consumers and markets in advance as part of their business plan to select appropriate emerging markets, and decide best possible entry modes.

To the best of authors’ knowledge, there is no comprehensive review article on this subject, which provides directions for future research. The authors fill this gap in the literature and suggest strategies with regard to market selection, entry modes, market adaptation, customer relationship development with a new four-dimensional model.

In this paper, using the antecedents, decisions and outcomes (ADO) framework, the factors/key performance indicators (KPIs) most relevant for creating or building a learning organization (LO) are identified. This study aims to contribute to the field of knowledge management (KM) in terms of introducing KPIs to foster a business organization with a continuous learning process, mechanisms of knowledge creation and memorization.

In total, 57 papers were selected for this systematic literature review (SLR) from Web of Science and Scopus covering the period 1985–2019.

The 12 most relevant KPIs are identified based on the literature survey conducted in the field of LO.

The managerial implications of this review paper will be an added advantage to the modern business organization worldwide that have adopted KM practices to foster knowledge management with information technology (IT) infrastructure. As IT infrastructure focuses on knowledge acquisition, dissemination and storage but the KPIs revealed through this review will help in transforming stored information as learning for the organization to improve its overall performance.

This review synthesizes prior studies and provides directions for future research.

The purpose of this paper is to present a case of proactive change that occurred in a large organization in Saudi Arabia.

The paper explains how management actively used religious discourse to institute a stakeholder perspective within the organization.

The process of change that occurred leads to the development of a successful change process that borrows from legitimacy theory and legitimation in discourse. The findings show the impact of religious discourse on organizational change in the context under study.

While this change process, grounded in religious discourse, cannot be assumed to work across contexts, future research can uncover what contextual or cultural dimensions facilitate or impede such an approach.

This study provides an example as to how change agents can engage people within their organizations in the change process through a systematic process of sensemaking that grants moral legitimacy to company's initiatives.

The paper draws attention to the importance of religious discourse in institutional change, a thing that has rarely been discussed at the firm level.

This paper explores the potential competitive advantages from the development of an internal network of subsidiaries and external network of alliances. Given the broad scope and lack of systematic investigation in prior research, clinical field research was conducted in eleven Japanese subsidiaries in China. Our in‐depth interviews revealed that there are benefits and costs associated with the development of both subsidiary networks and alliance networks. While there are exploitation and exploration benefits from subsidiary network development, internationalizing firms (especially smaller firms) are subject to the liability of foreignness. Alliance network development is an effective way to mitigate this liability if internationalizing firms choose the right alliance strategy.

The purpose of this paper is to analyze to what extent and in what ways signaling theory has been explored within the field of international marketing. This paper systematically reviews the use of signaling theory in the field of international marketing. Communication is a core aspect of the international marketing process. Research in this field has explored effective and unique ways of improving the communication flow to reduce the asymmetry of information between international consumers and the firm. This notion is adopted, enhanced and strengthened by signaling theory. Signaling theory has recently received the attention of international marketing scholars.

The systematic review methodology was applied for the purpose of identifying the relevant studies. We extracted academic articles over the last 23 years from the domain of international marketing that directly contribute to signaling theory based on 57 journal articles extracted through the systematic review process.

Based on systematic research the results reveal that the topic has grown and continues to expand within the broader international marketing field. We offer a theoretical conceptual framework to better understand signaling theory in the context of international marketing.

The authors map and critically evaluate the use of signaling theory in international marketing. Relevance of signaling theory in international marketing is growing and authors present an integrative framework that organizes the existing literature, and provides scholars to further expand on emerging themes of the domain. The paper offers some useful future research directions.

This paper attempts to explore and identify the growing segments of online buyers of premium brands in the context of the post-pandemic market in India. The multi-dimensional trait of fashion orientation has been used as the psychographic construct for segmenting young urban consumers who shop on e-commerce platforms.

An online study across major cities resulted in a sample of 555 urban consumers of premium apparel and accessories brands. Hierarchical, two-step and k-means cluster analysis were conducted to identify diverse consumer segments and arrive at a demographic and usage-based profiling of the clusters. Furthermore, one-way analysis of variance was conducted to assess the key drivers for an online purchase among the obtained segments.

The pioneering use of fashion orientation as a base for segmentation helped identify three distinct clusters of socially conscious fashionistas, fashion involved and fashion indifferent buyers. The study identified significant differences in the demographic composition as well as their usage patterns and purchase motivations to shop online.

The study looks at an extremely important but neglected category of premium brands. The distinct clusters of premium brand buyers highlighted by the study adds theoretical value as well as managerial insights for the premium brand marketer as they seek to target consumers in Asian economies.
