The purpose of this paper is to study the effect of surface salt spray duration on the fretting wear and electrochemical corrosion behaviors of Inconel 690 alloy.

A high-temperature steam generator was applied to salt spray test samples, a fretting wear rig was used to realize the damage behavior tests, an electrochemical workstation was applied to analysis the changes of each sample’s corrosion dynamic response before and after fretting wear.

The thickness of the oxide film that formed on sample surface was increased with the salt spray duration, and somewhat it could act as lubrication during the fretting wear process; however, the corrosive chloride would accelerate the fretting mechanical damage behavior.

In a salt steam spray condition, the fretting tribo-corrosion behaviors of Inconel 690 alloy surface was studied.

The rock drill’s drill tail experiences high-frequency fretting simultaneously in the rotational and axial directions. Due to the complex working characteristics and the low viscosity of the water medium, the pure water seal is susceptible to damage and failure. The purpose of this paper is to enhance the water seal’s performance.

The Y-shaped seal ring is modeled and simulated using orthogonal testing. Through analysis of the impact of various seal section parameters on sealing performance, the maximum contact stress and maximum Von Mises stress are selected as indicators of sealing effectiveness.

The maximum contact stress is proportional to lip thickness and chamfer length but inversely proportional to lip length. Meanwhile, the maximum Von Mises stress is directly influenced by lip depth and the included angle of the lip and drill tail but is inversely proportional to the lip thickness. The enhanced Y-shaped water seal sees reductions of 15% and 45% in maximum contact stress and maximum Von Mises stress, respectively.

This paper used analytical method and model that is helpful for design of the water seal’s structure in complex working characteristics and the low viscosity of the water medium.

Research for the case study was conducted using a combination of semi-structured interviews and secondary data sources.

This case traces the international expansion of Sadowsky Guitars’ bass guitar product line. Roger Sadowsky is one of the most respected instrument makers in the world and gained early acclaim for his outstanding repair and restoration work on guitars and basses. Some of his early clients included Prince, Will Lee (The Tonight Show), Tom Hamilton of Aerosmith, Jason Newsted of Metallica, Eddie Van Halen and Marcus Miller. Roger’s reputation and the demand for his instruments led to some customers having to wait for more than a year to obtain the chance to purchase a Sadowsky instrument, while others were unable to do so due to financial constraints. In 2003, Roger made the decision to form Sadowsky Japan to begin the contract manufacturing of more affordable Sadowsky instruments in Tokyo, Japan. As the company grew in size, Roger realized he was becoming more focused on running a business than building instruments. Furthermore, his Japanese partners were only interested in serving the Japanese market. This required him to handle the sales and distribution in the remaining parts of the world. In December of 2019, he announced a new, exclusive licensing agreement and distribution partnership between Sadowsky Guitars and Warwick GmbH & Co Music Equipment KG. The new agreement allowed Roger to continue running the Sadowsky NYC Custom Shop while Warwick would take over building and distributing the Metro instruments and a less-expensive, Chinese-built version of the MetroExpress instruments.

This case is appropriate for undergraduate and graduate-level courses related to marketing and consumer behavior. The case walks students through a real-life scenario when the founder of a well-known musical brand sought to expand internationally as a way to meet growing market demand. Students are asked to consider the advantages and disadvantages of the five key international market entry strategies: exporting, licensing, contract manufacturing, joint ventures and investment (equity/acquisition).

The case works well in the classroom, even if people are unfamiliar with the musical instrument retail industry. Participants are most likely aware of some of the artists and musicians mentioned in the case. Some may also be or know musicians. The instructor should be able to quickly engage participants in a lively discussion about Roger Sadowsky’s vision for his instruments and the opportunities and challenges of expanding product offerings and increasing market share.

Nanosensors have a wide range of applications because of their high sensitivity, selectivity and specificity. In the past decade, extensive and pervasive research related to nanosensors has led to significant progress in diverse fields, such as biomedicine, environmental monitoring and industrial process control. This led to better and more efficient detection and monitoring of physical and chemical properties at better resolution, opening new horizons in the development of novel technologies and applications for improved human health, environment protection, enhanced industrial processes, etc.

In this paper, the authors discuss the application of citation network analysis in the field of nanosensor research and development. Cluster analysis was carried out using papers published in the field of nanomaterial-based sensor research, and an in-depth analysis was carried out to identify significant clusters. The purpose of this study is to provide researchers to identify a pathway to the emerging areas in the field of nanosensor research. The authors have illustrated the knowledge base, knowledge domain and knowledge progression of nanosensor research using the citation analysis based on 3,636 Science Citation Index papers published during the period 2011 to 2021.

Among these papers, the bibliographic study identified 809 significant research publications, 11 clusters, 556 research sector keywords, 1,296 main authors, 139 referenced authors, 63 nations, 206 organizations and 42 journals. The authors have identified single quantum dot (QD)-based nanosensor for biological applications, carbon dot-based nanosensors, self-powered triboelectric nanogenerator-based nanosensor and genetically encoded nanosensor as the significant research hotspots that came to the fore in recent years. The future trend in nanosensor research might focus on the development of efficient and cost-effective designs for the detection of numerous environmental pollutants and biological molecules using mesostructured materials and QDs. It is also possible to optimize the detection methods using theoretical models, and generalized gradient approximation has great scope in sensor development.

This is a novel bibliometric analysis in the area of “nanomaterial based sensor,” which is carried out in CiteSpace software.

The purpose of this study is to identify LGBTQ+ perceptions of and experiences with hazards, vulnerabilities and disasters in the San Francisco Bay Area in the USA and to co-develop applied projects to “queer” disaster knowledge production and risk reduction activities in the region.

This is a community science project in which we collaborate with community members to enhance both community and scientific knowledge with the goal of utilizing it to produce a positive change to pressing social issues and their underlying causes. We do this through a series of four focus group workshops to identify community priorities, hazards, vulnerabilities and local action. We follow this with further ethnographic research and projects to apply findings from phase one.

The authors have found that: LGBTQ+ people in the Bay Area have unique experiences with hazards, vulnerabilities and disasters; there are significant gaps in the representation of LGBTQ+ hazard exposure in local scientific models that we can address through alternative methodologies; and tabletop exercises, learning modules and podcasts help orient and train disaster response agencies and personnel on LGBTQ+ inclusive operations.

This initiative entails novel approaches to community science for disaster risk reduction and creative collaboration with community-based organizations to foster the development of LGBTQ+ inclusive disaster risk reduction and response.

The goal of this study was to understand which employee-focused workplace practices and priorities – more formally known as human resource (HR) practices and priorities – employees with mental health and/or addiction challenges (MHAC) valued and how they perceived the day-to-day implementation of those practices and priorities in the workplace integration social enterprises (WISEs) that employed them.

Twenty-two WISE workers who self-identified as having serious MHAC participated in semi-structured interviews. Interviews were transcribed and coded to identify ways that employees did or did not feel supported in their WISEs.

Participants identified three HR practices and two HR priorities as important to establishing an inclusive workplace that accommodated their MHAC. The extent to which individual participants felt included and accommodated, however, was shaped by interactions with their supervisors and coworkers.

By evaluating the salience of WISEs’ employee-focused workplace practices and priorities through the lens of the employees themselves, our study articulates the critical role that interactions with coworkers and supervisors have in determining whether HR practices and priorities have the intended effect on worker experience.

This paper aims to examine the learning gained from the evolving adjustment experiences of co-workers in moving to home-based working during the COVID-19 pandemic and the influence of these experiences on re-adjusting to return to co-working.

Results of a longitudinal qualitative study are reported where a group of co-workers were interviewed on three occasions between 2019 and 2022. Experiences are analysed alongside the adjustment to the remote work model using a boundary management lens.

The main adjustment experiences were in work location, temporal structures, professional and social interactions, and a new adjustment area was identified around family role commitment that emerged in the home-based setting. Boundary management practices were temporal, behavioural, spatial and object-related and evolved with the unfolding of adjustment experiences. A return to using co-working spaces was driven by the need for social interaction and spatial boundaries but affected by the requirement for increased privacy.

This paper will help workplace managers to understand adjustment experiences and develop facilities that will support a positive shared working environment not fulfilled through home-based working.

Although many workers abruptly transitioned to home-based working during the pandemic, this research considers those who would normally choose to work in a community-centred working environment rather than being home-based. As such, their experience of adjustment is of greater interest, particularly in terms of their expectations for shared working spaces.

This study aims to investigate the dynamic interplay between the management control system (MCS) and organizational identity (OI) in the Deepwater Horizon incident involving British Petroleum (BP). It examines how the MCS manages challenges, particularly those addressing the embarrassment stemming from identity disparities between external portrayal (frontstage) and internal operations (backstage), with a focus on the often-underestimated influence of the media.

This study builds upon the frameworks developed by Ravasi and Schultz (2006) and Malmi and Brown (2008) to construct a theoretical framework that profoundly investigates the relationship between MCS and OI. The framework developed guided the research design and incorporated a qualitative approach complemented by an illustrative case study. The research data was rigorously gathered from diverse sources, including official BP documents and influential media outlets, with a particular focus on well-established American and British newspapers.

BP’s MCS plays a dual role: it exposes discrepancies in safety, leadership and values, causing embarrassment and identity damage, yet catalyses a sense-making process leading to organizational transformation and shifts in the OI. This transformation influences sense-giving and prompts changes in MCS. The study reveals an intricate interplay in identity management between frontstage audiences (e.g. influential media) and backstage actors (e.g. BP’s senior management). It highlights interdependencies both within and between MCS and OI, emphasizing their roles in interacting within identity management. The longitudinal recovery is intricately tied to mutual political interests between BP and the USA, which are significantly facilitated by the media’s role.

This study acknowledges limitations that point future research opportunities. Interviews could provide a more dynamic understanding of MCS changes and organizational transformations. Investigating the role of leadership, particularly the new chief executive office, and the influence of political versus organizational factors in shaping identity claims is essential. Additionally, the effectiveness and historical context of interdependencies should be quantitatively assessed. Theoretical limitations in the OI and MCS frameworks suggest the need for context-specific categorisations. This research serves as a foundation for further exploration of the intricate dynamics between MCS, OI and organizational responses to crises.

This study offers valuable insights with practical implications for organizations facing identity challenges in the wake of significant incidents. Organizations can better navigate crises by recognizing the multifaceted role of MCS in identity damage and restoration. It underscores the importance of addressing both frontstage and backstage aspects of OI while managing identity discrepancies, thereby enhancing transparency and credibility. Additionally, understanding the intricate interdependencies within OI and MCS can guide organizations in implementing more effective identity restoration strategies. Furthermore, the study highlights the significance of media influence and the need to engage with it strategically during crisis management.

This study’s findings have significant social implications for organizations and the broader public. By recognizing the multifaceted role of MCS in shaping identity, organizations can enhance transparency and credibility, rebuilding trust with the public. Additionally, the study highlights the critical role of media in influencing perceptions and decision-making during crises, emphasizing the importance of responsible and ethical reporting. Understanding the intricate interplay between MCS and OI can inform better crisis management strategies and improve how organizations respond to and recover from incidents, ultimately benefiting society by promoting more accountable and responsible corporate behaviour.

This study’s distinctness lies in its innovative exploration of MCS, which transcends traditional methodologies that focus narrowly on front or backstage aspects of OI and often adhere to predetermined MCS practices. It underscores the importance of concurrently addressing both the front- and backstage audiences in managing the embarrassment caused by identity discrepancies and restoration. The research uncovers multifaceted interdependencies within MCS and OI, and these extend beyond simplistic relationships and emphasize the complex nature of identity restoration management.

The COVID19 crisis has thrown wide open the debate on Europe’s Economic and Monetary Union’s (EMU) future. Next Generation EU (NGEU) has broken the stalemate over a central fiscal capacity. The open question is whether NGEU is a one-off or a first step. The suspension of the Stability and Growth Pact has given new urgency to the debate on reforming EMU’s fiscal rules.

There is no debate as yet about how these two prospects relate to each other. This paper argues that a permanent fiscal capacity and revised rules should be seen as alternatives.

This study makes two claims: first, a fiscal capacity renders a reformed pact unnecessary and second, that is an optimal solution politically. A fiscal capacity would provide an efficient asymmetric shock absorber and therefore reduce the need for pre-emptive action against negative cross-border externalities. It would also provide an abundant supply of an EU-wide safe asset around which to structure the EU’s financial system, thus rendering unnecessary the backstopping of member states' debts.

This would restore democratic accountability while eliminating moral hazard and enforcement problems.

The case is written based on publicly available data from primary sources such as the company’s annual reports, company website and the company’s presentations, as well as from secondary sources comprising newspaper articles, research papers, research magazines, magazine articles, industry reports, research reports, etc. as indicated in the references. The company’s financials and peer data are sourced from the Thomson Reuters Eikon database.

The case examines the financial position of Macy’s, Inc., America’s largest and one of the oldest premier departmental stores, with a consolidated annual turnover of US$18,097m in the fiscal year 2020/2021 (FY, 2021). Over the previous few years, the company had been struggling with decreasing market share and profitability mainly due to increasing competition from online retailers and deep discounters, which was affecting the company’s share price. With the appointment of a new chief executive officer (CEO) in fiscal year (FY) 2017, Macy’s, Inc. undertook several changes to revive its financial health and improve its market share. However, it still registered heavy losses of US$3,944m in the FY 2020/2021, the company’s first time in the past decade. With many retailers filing for bankruptcy, was there more that Macy’s could do to improve the company’s position and regain lost investor confidence? Will its entry into emerging markets play a crucial role in its turnaround?

The case can be used in undergraduate and postgraduate courses such as accounting for managers, financial statement analysis, management accounting, introduction to accounting and advanced financial statement analysis. The case can also be effectively used to understand the primary fundamental analysis of the company that involves understanding the company’s positioning and strengths, weaknesses, opportunities and threats analysis. The case would also help business management and entrepreneurship students to get a preliminary idea about the change management process. Finally, the case can be used to familiarize students with using Microsoft Excel to build financial analysis worksheets.
