This paper aims to investigate the influence of various laser texture parameters (diameter of pit, depth of pit and area density) on the tribological and tribo-vibration characteristics of tapered roller bearings (TRBs) under full oil lubricate conditions.

The laser surface texture parameters include: the diameter of pit (D: 60 µm, 100 µm, 200 µm), the depth of pit (H: 5 µm, 10 µm, 20 µm) and the area density (S: 6%, 12%, 24%). The outer raceway used laser marking device to prepare many regular pits. The tribological and tribo-vibration characteristics of pitting laser textured TRBs under full oil lubrication were studied by using the MMX-1A universal wear tester machine and vibration testing equipment. Through experiment and analysis, the effects of raceway pitting textures on tribological and tribo-vibration noise performance of TRBs were summarized.

When pit-textured TRBs operate under full oil, compared with the non-textured bearings, the average coefficient of friction and wear amount are significantly reduced. When D = 100 µm, H = 10 µm, S = 12%, average coefficient of friction = 0.00195 and wear amount = 0.12 mg, they are all at their minimum values. Compared to the same condition of non-textured groups, the coefficient of friction decreases by 66.6%, and the wear amount decreases by 79.3%. The energy from time-frequency and power spectrum analyses is mainly concentrated at high frequencies, with the signal power of pitting textured groups being lower than non-textured when the Y-direction is around 3600 Hz.

The experimental work can provide a reference for the investigation on the pitting textured TRBs.

This study aims to analyse the Corporate Insolvency Resolution Process (CIRP) in India, emphasizing the unique challenges faced by different sectors. It highlights that 45.23% of admitted cases result in liquidation or resolution, underscoring the need for sector-specific provisions in the Insolvency and Bankruptcy Code (IBC). The current framework’s limitations lead to higher haircuts and lower recovery rates. Sector operates under general provisions of IBC, which do not include specific clauses designed to address their particular requirements. The implementation of sector-specific strategies is essential for improving outcomes for both distress companies and their creditors. This approach will significantly enhance the efficacy of the insolvency resolution process.

This study uses data from the Insolvency and Bankruptcy Board of India (IBBI) through March 2024. It analyses 7,567 cases admitted under the Insolvency and Bankruptcy Code (IBC), 2016, focusing on sectoral insolvency across various industries such as manufacturing, real estate, constructions, hotels and restaurants, wholesale and retail trade, electricity, transport, storage, communications and others. It analyses data-driven decision-making approach by using formulas to calculate the key metrics such as insolvency rate, recovery rate and haircut rate from a large data set.

The overall insolvency rate is recorded at 45.23% with nearly half of the cases resulting in either liquidation or resolution plans. Out of the total cases, 2,476 resulted in liquidation, while 947 were resolved through approved plans. The recovery rate is 32.08%, indicating that less than one-third of admitted cases have been recovered. The average haircut rate is 67.89%, indicating substantial reductions in claims to facilitate resolutions. This sectoral analysis reveals that certain industries such as real estate and manufacturing are disproportionately affected, emphasizing the necessity for targeted interventions.

This study’s lies in its sector analysis and use of comprehensive data, from March 2016 to March 2024 from the IBBI. This paper caters to a unique sector and brings a novel viewpoint and valuable insights to the existing literature on insolvency processes in India.

This study explores the experiences of care-experienced people living in supported housing provided by the Rees Foundation in England. This study aims to understand the challenges faced by those over 25 who have aged out of statutory support and explores how the Rees Foundation’s services help address these challenges.

This study uses a qualitative approach, using semi-structured interviews with five tenants and five staff members from the housing project. Thematic analysis identified key themes related to homelessness, safety, stability and the importance of relationships with outreach workers.

The findings reveal that care leavers often face a “cliff edge” when statutory support ends, resulting in risks such as homelessness and social isolation. The Rees Foundation’s approach, which includes ongoing emotional and practical support, plays a crucial role in fostering safety, stability and hope among tenants.

This study offers original insights into the effectiveness of sustained support for care-experienced people beyond the age of 25, an age group that has been largely overlooked in existing research. By focusing on a population often neglected in care leaver studies, it highlights the need for extended support services to prevent long-term adverse outcomes, contributing to the broader understanding of post-care transitions.

Gymnasts worldwide have turned to media to speak out about their experiences of abuse in sport. More formally, services to report abuse have been recognised as important; however, we know little about athletes' experiences of the process. Therefore, we consider in this chapter how (former) athletes experience the process of reporting abuse and maltreatment. This chapter begins with a narrative poem that was created using direct quotes from an interview with a former gymnast, Lisa (pseudonym), who described her involvement with her national gymnastics federation's reporting process. We then examine reporting services and discuss the reasons why (former) athletes may not report abuse and maltreatment. As a conceptual framework, we present the pixie model of women's artistic gymnastics (WAG) as the root of the culture of fear, control and silence that prevents gymnasts from reporting their experiences, and discuss factors that enable the reporting of abuse and maltreatment. To illustrate the ways the WAG pixie model shaped Lisa's reporting experience, the poem presented at the outset of this chapter is extended to a narrative about her engagement with reporting processes. The chapter concludes with a call to put abuse and maltreatment on the sports governance agenda, the development of trauma-informed processes and further research on reporting abuse in sport.

The paper aims to provide a career perspective on self-employment (SE) by focusing on how engaging in SE shapes the career experiences of MBA graduates in a distinct cultural and institutional context.

We thematically analyse interviews with 29 Indian MBA graduates (including 10 women) who have engaged in both SE and salaried employment, using the conservation of resources (COR) theory as the theoretical framework.

Participants took up SE in a challenging institutional and cultural environment. Resources such as financial stability, social networks and family support enabled participants to pursue SE. Participants noted that the SE experience boosted their psychological resources, providing them with greater confidence, perseverance and self-awareness. Participants observed that SE had a negative impact on subjective career success (SCS) dimensions of financial success and positive work relationships but positively impacted other SCS dimensions such as entrepreneurship, learning and development, positive (social) impact and work–life balance (particularly for women).

Participants were highly educated with strong social networks from past work experience in a developing economy, so the transferability of the findings to other contexts may be limited.

Individuals could benefit from considering a broader career canvas that includes SE as a career option. Policymakers should work towards removing institutional barriers and changing cultural perceptions towards SE.

Our study is distinct in that it comprises participants who had engaged in both SE and salaried employment during their careers. Few studies have looked at the impact of one employment episode on another. We show that SE episodes can contribute to career sustainability by developing psychological resources.
