Tannic acid (TA) is one of the green corrosion inhibitors for mild steel; its anti-corrosive performance in alkaline water on mild steel when it is used together with polyaspartic acid (PASA) still has not been investigated. The purpose of this study is to develop an effective, biodegradable and environment-friendly novel corrosion inhibitor based on TA and PASA as an alternative to the conventional inorganic inhibitors for mild steel in decarbonised water, which is common in cooling systems.

Corrosion inhibition mechanism is investigated by electrochemical techniques such as polarisation measurements and electrochemical impedance spectroscopy, and results were evaluated to determine the optimum inhibitor concentration for industrial applications. Additionally, practice-like conditions are carried out in pilot plant studies to simulate the conditions in cooling systems. Thus, the efficiencies of the inhibitors are evaluated through both weight loss and linear polarisation resistance measurements. Moreover, the corrosion product is characterised by scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDX) and Fourier-transform infrared spectroscopy (FTIR) analysis.

TA shows high inhibition efficiency especially towards pitting corrosion for mild steel in decarbonised water. PASA addition in the cooling systems improves the inhibition efficiency of TA, and at lower concentrations of TA + PASA, it is possible to obtained better inhibition efficiency than TA alone at higher inhibitor amounts, which is essential in economic and environmental aspect.

A blended inhibitor program including TA and PASA with suggested concentrations in this work can be used as an environmental friendly treatment concept for the mild steel corrosion inhibition at cooling systems.

Treatment of intersectionality in empirical studies has predominantly engaged with individual categories of difference. The purpose of this paper is to demonstrate that there is utility in exploring intersectionality at the intersection of individual and institutional levels. As such the authors move beyond the polarised take on intersections as either individual or institutional phenomenon and tackle intersectionality as a relational phenomenon that gains meaning at the encounter of individuals and institutions in context. Therefore, the authors explicate how intersectionality features as forms of solidarity and hostility in work environments. As such the authors posit that not only individuals but also the institutions should change if inclusion is aimed at societal and organisational levels.

A thematic analysis on qualitative interview data of a purposive- and snowball-selected sample of 11 lesbian, gay, bisexual, transgender and queer working adults in Turkey was used.

This paper finds evidence to support the existence of a multidimensional model of intersectionality, where conflicting and complementary individual and institutional intersections create four intersectional typologies in the form of intersectional hostility, intersectional struggle, intersectional adjustment and intersectional solidarity.

The extant literature offers rich insights into individual intersectionality but sheds very little light on institutional intersectionality and its interaction with individual intersectionality. This paper attempts to fill in this gap by investigating intersectional encounters as interactions between the individual and institutional intersections.

As a result of accelerating globalisation, competitive dynamics of the world are rapidly changing. Nowadays, both small and large enterprises exist in the same arena, which was not possible before. Similarly, emerging countries have become both markets and competitors for developed countries.

In this chapter, competitive dynamics of Turkey, as an emerging market, will be analysed by evaluating export, import and production volume of the main sectors in Turkey. The concept of competitive positioning and also competitive positioning in emerging markets will be explained. Cases from different industries will be included in order to comprehend the big picture, to understand the competitive dynamics in Turkey and to show the roadmap in management and marketing of these companies. This chapter is planned to be a helpful tool to guide entrepreneurs and managers working in and with Turkish companies to survive and market their products in the Turkish market.

Coronavirus disease (Covid-19) has created uncertainty in all countries around the world, resulting in enormous human suffering and global recession. Because the economic impact of this pandemic is still unknown, it would be intriguing to study the incorporation of the Covid-19 period into stock price prediction. The goal of this study is to use an improved extreme learning machine (ELM), whose parameters are optimized by four meta-heuristics: harmony search (HS), social spider algorithm (SSA), artificial bee colony algorithm (ABCA) and particle swarm optimization (PSO) for stock price prediction.

In this study, the activation functions and hidden layer neurons of the ELM were optimized using four different meta-heuristics. The proposed method is tested in five sectors. Analysis of variance (ANOVA) and Duncan's multiple range test were used to compare the prediction methods. First, ANOVA was applied to the test data for verification and validation of the proposed methods. Duncan's multiple range test was used to identify a suitable method based on the ANOVA results.

The main finding of this study is that the hybrid methodology can improve the prediction accuracy during the pre and post Covid-19 period for stock price prediction. The mean absolute percent error value of each method showed that the prediction errors of the proposed methods were all under 0.13106 in the worst case, which appears to be a remarkable outcome for such a difficult prediction task.

The novelty of this study is the use of four hybrid ELM methods to evaluate the automotive, technology, food, construction and energy sectors during the pre and post Covid-19 period. Additionally, an appropriate method was determined for each sector.

This study aims to identify and understand the challenges, motivational factors and future needs of female entrepreneurs in Ankara, Turkey.

The study uses the qualitative analysis methodology and uses the qualitative data analysis software, MAXQDA 11. A total of 41 randomly selected female entrepreneurs from the city of Ankara and rural areas of the Ankara region participated in semi-structured in-depth interviews. A total of 284 codes were defined.

Results indicate that female entrepreneurs are mostly intrinsically motivated and are driven by the desire to achieve and to become independent. The socially constructed role of women in Turkey is the primary challenge faced by female entrepreneurs in both urban and rural areas. Moreover, the major future needs identified for female entrepreneurs are support from public institutions and access to managerial consultants.

There are limited number of studies that closely examine the characteristics of female entrepreneurship activity and their challenges/motivations in Turkey. This research contributes to the existing literature through its qualitative nature and by highlighting differences in urban and rural female entrepreneurs. Moreover, the results of this study are useful for policy makers to evaluate the future needs of female entrepreneurs and the programs that will be needed to overcome the challenges facing female entrepreneurs in the entrepreneurial process.

Rooted in Joan Acker’s “gendered organisations” framework, this paper aims to explore the impact of employee’s developmental performance management systems (DPMSs) on occupational wellbeing, highlighting gender and age-based intersectional disparities within organisations.

This study uses data from a sample of more than 600 Italian employees and investigates with a three-way interaction, the effect that DPMS have on employee’s occupational wellbeing by considering the intersectionality between gender and ages’ categories.

The findings dismiss the idea that DPMS can be regarded as a practice for inclusion. Moreover, the analysis discloses the need for intersectional perspective as the authors do reveal different effects of developmental performance system adoption on occupational wellbeing for people in diverse intersections of genders and ages.

This paper expands on Acker’s tradition with a focus on age, dismissing the possible inclusive outcome of competency based employee performance systems.

This study aims to explore the individual lived crucible experiences of women leaders in higher education (HE) and business as the catalyst to investigate organisational inequality regimes that prevent women leaders from fully participating, contributing and flourishing at work. Drawing upon Bolman and Deal’s four-frame theoretical organisational model, this study analyses women’s lived crucible leadership experiences to better understand the organising processes and practices that render intersectionality invisible that reinforce and perpetuate inequality regimes.

A collaborative autoethnographic research method was selected for data collection. The research team members each selected one significant crucible moment from their professional career and used the Gibb’s six-part reflective cycle to document their narrative and reflect on their leadership experience. A reflexive thematic analysis was used based on Braun and Clarke’s six phases.

The study features the importance of creating a climate in organisations that acknowledges the need for greater equity, diversity and inclusion (EDI) to support women leaders. Four global themes emerged from the analysis of the leadership narratives: organisation, power dynamics, emotional distress and perseverance and intersectionality. These themes illuminate a greater understanding of organisational life for women and confirm the presence of inequality regimes of gender and race.

This is the first study to explore the impact of women leaders’ crucible experiences through the lens of the Bolman and Deal’s model that highlights the need to consider an EDI lens as the fifth frame.

This paper aims to describe and explain women's labor participation in the public sector, particularly at the local level. The paper analyses the representation of women employees in the public sector through a case study of a city council in a mid-sized Spanish city. The authors delve into the extent of gender labor discrimination in public administration, exploring a diversity of situations, experiences, and perceptions of women workers in female, neutral, and male-dominated areas in the local administration.

The authors have applied a combined methodology of quantitative analysis based on an exhaustive analysis of the list of job posts, and qualitative analysis from the narratives of women workers in biographical interviews, in women-dominated, neutral and male-dominated areas.

The authors conclude by providing a clear description of women's representation in local administration. Despite the institutional efforts in applying gender equality norms and public policies in administration, employment and labor market, this article shows the persistent inequality in employment within the administration. The paper demonstrates that public administrations can be seen as gender regimes that tend to reproduce inequality by formal and informal dynamics. This inequality gender reproduction in a supposedly gender-neutral administration reflects discrimination in a labor market. The paper details phenomena relating to horizontal occupational segregation, glass ceilings, sticky floors, and the undervaluing of women's work, among other phenomena.

The administration should consider two essential factors that endanger gender equality: (1) the demonstrated regression of gender mainstreaming and the effects on women's employment as a consequence of the crisis, and (2) neoliberal governments and extreme right-wing parties (or neoliberal governments and extreme right-wing parties' support, as is the case with the current Andalusian regional government), whose agenda includes the fight against what neoliberal governments and extreme right-wing parties call “gender ideology”.

The gap between the effectiveness of gender legislation and actual working practices within the administration has been highlighted. This fact should be a wake-up call for the administrations to strictly comply with gender legislation, given that local administrations are the closest to the citizens. Future research should focus on changes to detect any regression and to prevent losing the improvements already achieved, which can still be very much strengthened.

This article helps to fill the gap in the literature on gender discrimination in the labor market, which often omits the public sector, especially in local administration, which is the closest administrative structure to citizenship respecting public policies. The article contributes to highlighting the need for an egalitarian labor market in order to achieve optimal performance, commitment and efficiency in egalitarian labor relations in local administration.
