Title: Multi-objective optimization of hydrogen-integrated hybrid renewable energy systems using an adaptive evolutionary framework Authors: Khan, WA; Pakseresht, A; Chua, C; Yavari, A Abstract: The optimization of Hydrogen-Integrated Hybrid Renewable Energy Systems remains challenging due to conflicting objectives, nonlinear operational constraints, and the limited adaptability of conventional evolutionary algorithms. This study introduces an adaptive Non-dominated Sorting Genetic Algorithm II (NSGA-II) framework that integrates dynamic mutation, selective local search, constraint-aware offspring generation, and cross-run learning. The method is applied to a residential-scale hybrid hydrogen–renewable energy system in Broadmeadows, Melbourne, comprising photovoltaic panels, wind turbines, battery storage, proton exchange membrane electrolyzers, hydrogen tanks, fuel cells, and diesel backup. Four objectives are considered: levelized cost of electricity (LCOE), carbon dioxide (CO₂) emissions, non-renewable hours (NRH), and renewable energy fraction (REF) penalty. The optimization is performed within a dispatch-coupled model that enforces hourly energy balances and state-of-charge limits, supported by demand and resource forecasts generated using extreme gradient boosting models trained on long-term meteorological data. The proposed adaptive NSGA-II achieves stronger performance than the conventional NSGA-II across hypervolume, Pareto diversity, and convergence indicators. The optimal designs favor greater storage capacity, with battery capacity rising from 105 MWh to 112 MWh, hydrogen storage increasing from 0.39 tons to 1.0 ton, and electrolyzer capacity growing from 4.8 MW to 5.2 MW. These adjustments reduce LCOE from 5.9169 to 5.8083 AUD/kWh, lower annual CO₂ emissions by 45% (from 94 tons/year to 52 tons/year), improve REF from 82.34% to 88.41%, and decrease NRH from 103 to 53 h. The results demonstrate that adaptive NSGA-II produces balanced solution portfolios that support high renewable utilization, reduce reliance on fossil backup, and provide practical insights for planning hydrogen-integrated sustainable energy systems.

Title: Hysteresis in the neoliberal academy: inside- and outside-track academic lives under authoritarian neoliberalism Authors: Özbilgin, MF; Erbil, C; Akçomak, S; Temel, S; Karaosmanoğlu, E; Ünlü, H Abstract: Hysteresis in the neoliberal academy emerges as inherited academic dispositions collide with performance-driven governance under authoritarian neoliberalism, producing inside- and outside-track academic lives. We examine how neoliberal reforms in higher education in Turkey have restructured academic performance, generating uneven experiences for academics positioned within (inside-track) and against (outside-track) the dominant political orthodoxy. Drawing on Bourdieu’s concept of hysteresis, we show how the rapid transformation of institutional logics has produced temporal disjunctures between academic habitus and field conditions. Our qualitative analysis of responses from 2,023 Turkish academics reveals how inside-track academics tend to justify and benefit from the performative turn, while outside-track academics resist or are marginalised by it. This study makes an original contribution by revealing the embodied dynamics of field misalignment and offering a novel conceptualisation of insider/outsider positioning in academic careers under neoliberalism. We show how performance regimes govern voice as well as productivity, reproducing patterned orientations of orthodoxy and heterodoxy with implications for governance, leadership, and evaluation design in higher education.

Title: “Cis Hell” Authors: Sehlikoglu, S; Özbilgin, MF Abstract: This paper develops the concept of cis hell to describe the regulatory normativity over all bodies based on gender biopolitics as a global political pandemic. Centring the recent UK Supreme Court’s 2025 Equality Act ruling and connecting it to similar examples across the world, we demonstrate how biopower operates through social movements inspired by the new authoritarianisms to establish transnational regimes of bodily control. Drawing connections between trans exclusion in the UK, USA and pronatalist policies in Turkey, Hungary, and Russia, we argue these seemingly disparate developments represent coordinated manifestations of biopolitical logic reducing human worth to reproductive capacity. Authoritarian innovation threatens and destroys modest progress towards human rights for vulnerable groups. ‘Gender-critical’ activism, despite protection claims, functions within a broader masculinist restoration project threatening collective prosperity by constraining human potential and re-centring white, male, and cis supremacy. The purported ‘safety’ of cisgender categorization creates a hell of rigid taxonomies undermining human flourishing across the gender spectrum, necessitating a radical reimagining of gender justice as essential to global prosperity through participative co-design processes inherent in new social movements theory focusing on social identity, human potential, and affect.

Title: Navigating Challenges, Embracing Opportunities: An Assessment of Women’s Leadership and Career Advancement in Africa, with a Focus on Nigeria Authors: Adeoti, A Editors: Ologunoye, OT; Mordi, C; Olatunji, DA Abstract: A gendered ideology and a gendered hierarchy are prominent components that impact African women’s leadership and career advancement. By considering extant literature, empirical evidence, and expert insights on this topic, the aim of this chapter is to understand the dynamics surrounding women’s leadership and career advancement in Africa, specifically Nigeria. It delves into Nigeria’s history and culture, examining the impacts of gender roles, societal expectations, customs, and legal barriers hindering women’s leadership and career advancement. Providing insights into preconceptions of females based on their gender, this chapter’s assessment reveals that sociocultural practices, female gender bias and marginalisation, a lack of education for young girls, poor access to education, a lack of legal provisions encouraging women’s empowerment, geographical factors, and religious proscriptions determine or unfavourably impact women’s leadership and career advancement. While this assessment focuses on women’s leadership and career advancement in Nigeria, thereby limiting its generalisability, it considers how to create sustainable leadership and career advancement opportunities for women, strategies for fostering a more inclusive and supportive environment for women, and recommendations for promoting gender equality, empowering women leaders, and inclusive career pathways.
