Ensuring the safety of structures is important. However, when a structure possesses both an implicit performance function and an extremely small failure probability, traditional methods struggle to conduct a reliability analysis. Therefore, this paper proposes a reliability analysis method aimed at enhancing the efficiency of rare event analysis, using the widely recognized Relevant Vector Machine (RVM).

Drawing from the principles of importance sampling (IS), this paper employs Harris Hawks Optimization (HHO) to ascertain the optimal design point. This approach not only guarantees precision but also facilitates the RVM in approximating the limit state surface. When the U learning function, designed for Kriging, is applied to RVM, it results in sample clustering in the design of experiment (DoE). Therefore, this paper proposes a FU learning function, which is more suitable for RVM.

Three numerical examples and two engineering problem demonstrate the effectiveness of the proposed method.

By employing the HHO algorithm, this paper innovatively applies RVM in IS reliability analysis, proposing a novel method termed RVM-HIS. The RVM-HIS demonstrates exceptional computational efficiency, making it eminently suitable for rare events reliability analysis with implicit performance function. Moreover, the computational efficiency of RVM-HIS has been significantly enhanced through the improvement of the U learning function.

We analyse the practices of distributed leadership exercised by principals in two Spanish primary schools. We provide evidence in this area. The study is framed in the Spanish context, in which autonomy is limited and the trend from the administration is the promotion of a distributed leadership model.

We carried out a multi-case study using interviews and shadowing sessions with the principals, observation records of meetings and interviews with other non-formal leaders from each school. The qualitative analysis identified actions and limitations that reflect the leadership exercised by the management.

The outcomes reflect the remarkable role of executive action and the preeminence of formal and bureaucratic components in the development of distributed leadership. Likewise, the difficulties derived from its implementation allow us to conclude that leadership is caught between a bureaucratic supervision that conditions its development and certain attempts and initiatives, not fully resolved, to move towards a collective leadership that incorporates other members of the school.

Lies in the methodological approach employed. And in the use of instruments that have required researchers’ constant and prolonged presence in schools. In the cases studied, collaboration and interactions are gradually building new forms of leadership. Principals are becoming aware of their role and how to improve their schools by giving their teachers greater autonomy and prominence, gradually contributing to the development of collective leadership. The need to change bureaucratic structures, furthering interactions and diverting attention to other non-formal leaders, is reinforced.

This paper aims to study the elasto-dynamic behavior of additively manufactured metallic lattice implants and compare them with human lower-body bone. This work is a step toward producing implants with high similarity of material properties to bone by developing a dynamic design approach.

A suitable topology was selected and admissible design space was established. Implants were fabricated by selective laser melting. Material dynamics, including elastic modulus, damping and natural frequency, were analyzed with experimental and finite element method methodology.

Generally, porosity improves dynamic properties up to an optimum point, which depends on printability, that is, ∼70%. Regarding elastic modulus and natural frequency, it is possible to achieve enough similarity with bone. But, considering damping, the similarity is <23% and <12% with dry and fresh bone, respectively. Damping and strain rate sensitivity increase with porosity. The natural frequency decreases with porosity. Bone ingrowth into lattice implants improves damping substantially while increasing elastic modulus.

Designers, dominantly had quasi-static approach, which considered only elastic modulus. But, the human body is a dynamic structure and experiences dynamic loads; meanwhile, bone, with its damping and natural frequency, regulates dynamic events like shock absorption and elastic wave filtering. Importantly, bone cells sense no load in quasi-static loading and must receive impact loads near their natural frequencies and special accelerations to conduct optimum mechanotransduction. So, it is necessary to develop a dynamic strategy which is comprehensive and describes bone duties.

This paper examines the moderating role of firms’ litigation environment on the association between gender diversity and financial reporting quality.

This study draws on a sample of US firms to examine the moderating role of firms’ litigation environment on the association between gender diversity and financial reporting quality. Firm-specific financial data come from Compustat. To measure the firms’ litigation environment, we use state-level datasets from the Lawsuit Climate Survey conducted for the US Chamber Institute for Legal Reform by the Harris Poll.

Findings suggest that firm litigation environment moderates gender diversity, as defined by female members on the board to subdue our first proxy for financial reporting quality (accruals-based earnings management), but our second proxy for financial reporting quality (real-activities manipulations) increases in a firm’s litigation environment. To the extent that our results hold after controlling for firms’ reputation indicates that female members on the board are sensitive to reputational loss and protect firms’ reputation in a litigation environment.

The study is based on a specific country, limiting the generalizability of the findings.

The findings provide support for promoters and advocates of gender diversity in corporate boards. Specifically, it shows the importance of gender diversity policies in business and society.

This study is the first to examine the moderating role of firms’ litigation environment on the association between gender diversity and financial reporting quality. The study provides novel evidence and shows that the litigation environment moderates gender diversity to improve financial reporting quality in the short-term (by decreasing accruals manipulation). In firms’ litigation environment, when female members on the board are restrained from engaging in accruals earnings management, they shift to value-destroying and costly real activities to maintain reputation and firm performance. To the extent that we control for the potential effects of firms’ reputation and financial performance, our findings suggest that ethical concerns are likely to drive female members on the board to produce high-quality financial reports.

The purpose of this study is to investigate how social capital resources (SCRs), proactive personality and perceived organizational support (POS) influence work engagement during the organizational socialization process through the lens of self-determination theory (SDT).

Drawing upon a sample of newly hired employees from diverse industries, data was collected using self-report measures. A total of 619 respondents’ data were qualified for analysis. Regression analysis and structural equation modeling with the bootstrap method were used for hypothesis testing.

Results indicate that newcomers who used effective organizational socialization tactics (OSTs) experienced higher levels of work engagement. Moreover, SCRs were crucial in shaping the relationship between OSTs and work engagement. Specifically, newcomers with greater SCRs exhibited increased work engagement, enhancing effective OSTs’ positive impact. Furthermore, proactive personality and POS traits moderate the relationship between SCRs and work engagement. Newcomers with a proactive personality were more likely to leverage their SCRs, leading to higher work engagement effectively.

This study underscores the importance of promoting social connections, organizational support, proactivity and positive relationships to enhance employee work engagement and overall well-being in the Pakistani context.

This study examines how SCRs, proactive personality and POS influence work engagement during organizational socialization, a novel area in newcomer adjustment. It highlights the importance of strategic socialization and targeted onboarding programs that enhance SCRs and proactive personalities. By integrating SDT with the cultural context of Pakistani organizations, it offers unique insights for improving newcomer adjustment and engagement.

Firms with gender diverse boards have been shown to have increased transparency and disclosure, resulting in reduced information asymmetry, which is a key factor influencing stock liquidity. This paper explores the influence of information asymmetry resulting from board gender diversity on stock liquidity. We examine the impact of gender diverse firms on stock liquidity in US listed firms from 2006 to 2022, capturing 28,280 firm-year observations across 4,349 firms. Using mediation models, we distinguish between direct and mediated effects to examine the impact of gender diverse boards on three dimensions of stock liquidity. We find a positive and significant relation between board gender diversity and stock liquidity, and our findings highlight the substantial mediating role of information disclosure in this association. To address concerns of endogeneity, we use instrumental variables regression, and our conclusions remain robust to a range of alternatives.

To investigate the association between board gender diversity and stock liquidity and the underling mechanism that drives the relation, we utilize a dataset comprising 4,349 listed US firms from 2006 to 2022. We adopt a comprehensive approach to measure stock liquidity that spans three dimensions: Amihud illiquidity (LIQ) as a representation of price impact, the quoted spread (SPREAD) to gauge transaction costs and the stock turnover (TURNOVER) to assess trading frequency. To evaluate board gender diversity, we examine female directors and female independent directors, utilizing both the percentage and the presence (as a binary variable).

The results of our analysis reveal not only a statistically significant effect of board gender diversity on liquidity but also demonstrate its economic significance. One standard deviation increase in the percentage of female directors (12% more female directors) is associated with a 5.8% decrease in price impact, a 5.1% reduction in transaction costs and a 3% increase in trading frequency. These findings highlight the material economic importance of the relationship, which stands in contrast to previous studies reporting only a 1% change in average stock liquidity in the Australian stock markets (Ahmed and Ali, 2017). To further investigate the underlying mechanism driving the association between board gender diversity and liquidity, we employ mediation models to separate the direct and mediated channels. Our results indicate that the effects of the percentage of female directors are mediated on liquidity (LIQ, SPREAD, and TURNOVER) through information disclosure, albeit with a relatively small magnitude (mediation proportion is 18.2, 3.9 and 22.9%, respectively).

We include a comprehensive set of variables in our analysis and adopt an instrumental approach to mitigate endogeneity concern. However, we acknowledge the possibility of omitted variable biases or reverse causality in our empirical analysis.

Our study contributes to the understanding of the association between board gender diversity and stock liquidity, focusing on the underlying mechanisms. Gender diversity on boards enhances corporate governance, leading to reduced managerial opportunism (Adams and Ferreira, 2009; Nielsen and Huse, 2010). This, in turn, increases information transparency and results in increased stock liquidity. By exploring the empirical evidence of the impact of gender diverse boards on stock liquidity through the information channel, we provide valuable insights to the existing literature. Our study uses US data to examine this association, addressing the small sample concerns of prior research that may have contributed to inconsistent findings.

This research can drive both economic and social transformations as it provides evidence that gender diverse boards lead to improved market outcomes.

Our study differs from previous research by incorporating all three dimensions of liquidity, ensuring a comprehensive analysis. Through our investigation, we aim to deepen understanding of how gender diversity on corporate boards shapes market dynamics and contributes to understanding of corporate governance and market efficiency. Our study investigates how the impact occurs by employing mediation models to separate the direct and mediated channels of impact. We show that the effects of gender diverse boards on liquidity are mediated through information disclosure.

In this paper we explore the gendered ways in which academic staff resistance and compliance is configured in a post-1992 University in England, including the emotions implicated in the navigation of neo-liberalisation and research intensification of their academic institution and its associated disciplinarian mechanisms.

We draw on data from an interview study of a diverse sample of 32 academics of different gender, discipline and academic grade. Analysis informed by a feminist post-structuralist framework of power and discourse explored different forms of academic resistance and compliance; how the embodied academic subject was (re)negotiated within gendered discourses of neo-liberal research excellence and managerialism and the gendered emotions generated in processes of resistance and compliance.

Institutional change and expectations to engage with research performativity generated fear, anxiety and anger. Female staff appeared to actively resist the masculinized research subject performing all hours work and individualism in the context of private and institutional gendered relations and labour. Male staff though actively resisted the feminization of higher education and the neo-liberal instrumentalization of caring and therapeutic cultures and ideologically resisted the surveillance mechanisms of higher education including the REF.

Our work contributes to scholarship problematizing the assumed neutrality of resistance and compliance and highlighting women’s symbolic struggle to (dis)identify with a masculine professional norm. In terms of theorising academic resistance to neo-liberalism and identity construction, further attention should be given to the mobilization and symbolic capital of academics and emotions positioned differently due to their gender and intersecting differences.

Our study addresses a gap in the scholarship of academic resistance and compliance by advancing the understanding of gender inequalities and emotions implicated in the process of resistance and compliance against neo-liberalism.

The purpose of this study was to examine the internalization of group-level identities held by people who are on the sex offense registry and how these influence emotions and the willingness to accept treatment. The types and consequences of identities and stigmas are often examined at the individual level, but most people belong to groups that hold collective identities that can be detected in phrases such as “we, us, our,” etc.

Longitudinal data from 2008 to 2024 was used to examine registrant’s group identities. Interviews were conducted with 115 registrants and 40 of their family members, and narrative research analysis was used to assess how participants’ levels of liminality influence why some on the registry never come to see themselves as sex criminals.

Three group-level identities were found that corresponded with varying phases of liminality. The first group had a fixed mindset, no liminality and a strong sense of self. The second group of registrants had liminoid experiences, allowing them to change the way they saw themselves over time. This group had a growth mindset that believed change was attainable. The third group exhibited fixed mindset, as they either always saw themselves as sex criminals and required no transition or came to see themselves as sex offenders post-punishment.

To the best of the authors’ knowledge, there are no studies that have examined group-level identities among people convicted of sex crimes or what the consequences of group identities have on behavior.

This article proposes diffractive vignettes as a new analytical approach that can sensitize organizational communication research to extra/linguistic forces in the communicative constitution of major societal challenges such as the climate crisis. The critical feminist concept of diffraction examines how diverse forces interact, interfere and produce new patterns of meaning and difference through entangled, performative relations.

Diffraction as an analytical tool is illustrated based on fieldwork on organizing the climate crisis in the tourist destinations in the Tyrolean Alps and Venice. We analytically attune to how extra/linguistic forces move and resonate with us, how we read them through each other in a diffractive experiment and how they allow us to attend to materialization differently through crafting diffractive vignettes.

We account for how the analytical work required us to experiment with juxtaposing, weaving, dividing and melting data and theories together through non-representational, post-qualitative ways of analyzing. Through a diffractive vignette, we then unfold how the extra/linguistic forces became agentic for the constitution of the climate crisis.

Through diffractive vignettes, we extend a fast-developing body of work on materialization within organizational communication to analytically exploit communication’s performativity, including its extra/linguistic forces in a post-qualitative, non-representational sense. With diffraction, we expand the analytical potential of organizational communication scholarship with a sensitivity to difference in materialization.

The natural ventilation in tall buildings is significantly different from that in low-rise buildings. It is imperative to record the wind available on site as a prerequisite for designing wind-driven natural ventilation. This paper aims to establish the significance of collecting site-based wind data and highlights the gap between the observed wind speed and the one used in practice.

The method consists of experimental study to determine the available wind speed for a 100-metre-high building in a warm and humid climate. The analytical mathematical model that uses the interpolation method based on secondary wind data was used to equate wind velocity at such heights. The study compares both methods to understand the gap in predicting the vertical wind profile.

The existing practice of using a wind rose and predictive mathematical model needs to be confirmed with site-based wind data before being used as an input parameter for designing for natural ventilation on upper floors.

Further studies can be undertaken to establish the variation of wind speed at the midriff of the building, derive an average rate of decrease in wind velocity and give a generalised wind input as a design guideline. A correction factor for the change in wind velocity can be helpful in determining the wind profile in the vertical component closest to the real-time data. The study is limited to outdoor wind velocity at various heights encountered at the windward side of the building. The study is region-specific.

The practice by designers and architects to use wind rose, composed of wind data available at 10-metre height, to design for naturally ventilated high-rise buildings is redundant. The study shows that the wind velocity profile changes beyond 20 metres. The prospect of a sustainable high-rise project is dependent on efficient natural ventilation, and hence the input wind velocity cannot be generic.
