The purpose of this manuscript is to investigate the influence of the satisfying of plane strain conditions on the prediction of the localized necking and to evaluate this effect by the different hardening models.

High-order anisotropic Drucker yield function, two types of hardening models, namely Hollomon power and Voce saturated, and the modified maximum force criterion (MMFC) are employed to predict the forming limit strains of AA3104-H19 alloy. Two identification methods, namely conventional and plane strain constrained, are applied and forming limit diagrams of the material are predicted by the incorporation of the anisotropic Drucker criterion and the hardening models into the MMFC for both calibration methods.

The enhancement in the prediction accuracy of the forming limits provided by the implementation of the plane strain constrained method is strongly dependent upon the selected hardening model type in the MMFC. About 18% improvement in the prediction of the biaxial limit strains is provided via Hollomon power law hardening, whereas the opposite result is occurred in case that the Voce saturated hardening law is used, and the predictions match with the experimental data only in the plane strain point and its surroundings.

The plane strain constrained identification method precisely predicts the location of the plane strain point on the yield locus and also any yield stress or anisotropy coefficient in the plane strain state is not required during the calibration, therefore the method can reduce the number of the required experiments for the constitutive characterization, and it will be attractive for both academy and industry. Additionally, the improvement in the prediction of the biaxial forming limits can be provided by applying of this method along with the appropriate hardening law.

The purpose of this paper is to explain the effect of perceived ethical leadership and perceived distributive justice on internal whistleblowing intention through trust in leader as a mediator.

Following an empirical design, data were collected from 1,296 employees of Turkish financial institutions, located in Istanbul. To test four hypotheses structural equation modelling was applied.

Results reveal that trust in a leader fully mediates the positive effects of both ethical leadership and distributive justice on the internal whistleblowing intention.

This study enhances the understanding of the ethical leadership perception and distributive justice affecting the internal whistleblowing intention in Turkey that is a developing country. Although numerous studies on whistleblowing have been conducted, this study’s originality and contribution lay in the examination of trust in the leader as a missing link between the direct relations.

Consumption is a way of communication whereby consumers express, position or/and differentiate themselves within their society or affiliated groups. A great part of consumers’ lives are spent on various purchase activities, and many would be eager to understand the factors underlying those behaviours.

This chapter primarily deals with the cultural, social, psychological and personal factors that affect consumer behaviour. Each of these factors in relation to consumer behaviour is discussed in detail. The types of consumer buying behaviours and the consumer decision-making processes then provide the fundamentals of the topic along with their relevance to Turkish consumers.

As media texts, advertisements use representation practices to construct ideological meanings. This study traced the representation of the worker in advertisements with the help of content and thematic analysis. The study aimed to reveal the representation of the worker in the advertisements and to make the representations of the worker built through advertisements visible. The study was limited to ads that received an Effie Award in Turkey in 2020 and 2021. In the 2020 Effie Awards, 73 awards were given in 41 categories and in the 2021 Effie Awards, 68 awards were given in 42 categories. Content analysis was applied to 24 advertisements in 2020 and 31 advertisements in 2021. The quantitative data helped to determine the themes in the thematic analysis. Thematic analysis was carried out by regarding the worker as the (in)visible, the (un)voiced, and the bypassed. This study, which reveals that the worker is represented in advertisements through being invisible, unvoiced, and bypassed, claims that the labor of the worker in the production process is ignored through representation practices. In this context, it can be said that the worker is erased and omitted in TV ads on a symbolic level.

This study aims to investigate the impact of online collective feminist actions on social media participation and the perceived value of social media as part of the social identity model of collective action (SIMCA).

A mixed methodology is used. Within the SIMCA model in the context of feminist collective actions, social identity, group-efficacy and fear predicted the intention of online collective action participation in the first part (quantitative) of the study. Contrary to predictions, the influence of anger on the intention to participate in collective action was negative. In-depth interviews are conducted in the study’s second (qualitative) part to investigate why individuals do not participate in collective actions despite their anger at violence against women.

The concept of online feminist collective action, from the perspective of the SIMCA model, deals with violence against women in the context of social marketing, revealing the importance of online collective actions as an antecedent of social media participation and the perceived value of social media. The possible causes of the negative impact of anger, which is an important emotion within the framework of the SIMCA model, on online feminist collective action were determined, and a contribution was made to the social marketing literature in the context of women’s rights.

The study makes three major contributions to the literature. First, women’s rights are addressed in the context of online collective action, an issue that has received little attention in social marketing. Second, in the context of the social identity theory of collective action, online collective feminist action and its predecessors are addressed. Finally, the Turkish case is used to highlight the probable causes of anger’s negative impact on collective action.

Although the design studio has formally been the locus for design education, informal education approach has gained more and more acceptance in the world. Informal education, which is the education outside the confines of curricula, includes the acquisition of knowledge and skills through experience, reading, social contact, etc. Workshops cover the essential weight of this informal education. Although the role of the design workshops in architectural design education has been very limited through overall design education’s past, many schools of architecture have taken steps to consider workshops as the part of informal learning and education.

“Culture and Space in the Build environment” (CSBE) Network of IAPS have been organizing “culture and design workshop series” for graduate and post graduate students in Turkey since 2001. In these workshops, a design teaching approach based on the conceptual framework of culture and space interactions is applied. The conceptual framework developed for the architectural design education, takes three fundamental starting points for workshops as the part of informal design education: as a tool for informal design education (method), as a tool for learning & understanding culture-environment relations (content), and as a tool for awareness of different environments/contexts (scale/place). The foundation of the conceptual framework is based on the general approach that discusses the “architectural design process” with regards to environmental context and content.

Within this context the aim of the paper is to discuss and evaluate the importance and the contribution of workshops as tool for informal architectural design education. These discussions will be held on the case of IAPS-CBSE Network’s last workshop “Istanbul as a Palimpsest City and Imperfection”. In the paper, the process, the method, the content and the results of workshop studies will be discussed and evaluated.

The purpose of this paper is to enhance the limited fluorescence of mica titania (MT) effect pigments by coating them with peripherally substituted zinc phthalocyanines (ZnPc).

The effects of deposition medium, temperature, time, initial organic pigment/MT ratio on deposition behaviour and efficiencies were investigated separately for ZnPc, nitro (TNZnPc) and amino (TAZnPc) substituted ZnPc’s.

TNZnPc could be deposited in the form of well-defined crystals on MT with per cent 64 ± 5 efficiency in chloroform at 50°C within 5 h and the amount deposited was linearly dependent on the initial TNZnPc concentration. TNZnPc fluorescence emissions, which appear mainly at 460 and 685 nm in pure pigments, could be observed in combination with MT (MT-TNZnPc) as well. A spectral analysis on the non-overlapping region of the spectrum with two different excitations (385 and 630 nm) revealed that, respectively, up to threefold to sixfold increase is possible to attain, depending on the excitation wavelengths.

Efficiency of deposition could not be taken above per cent 11 ± 4 with TAZnPc. Although ZnPc could be deposited with per cent 57 ± 3 efficiency, the pigment was not effective in imposing its fluorescence characteristics over MT.

Combining inorganic effect pigments with organic dye molecules is an idea that has been elaborated mainly for producing different colour effects and stabilization of dye molecules against agglomeration. Here, for the first time, it is used to enhance the fluorescence of the effect pigments.

Given that slow fashion is a movement that develops a comprehensive understanding of sustainable fashion and it is little explored in the Brazilian academic field, this study aims to analyze the influence of empowerment and materialism on slow fashion consumption.

Data were collected via an online survey, and quantitative methods were applied to analyze the sample of 306 clothing consumers from Fortaleza, the 5th largest Brazilian city and capital of the State of Ceará, which ranks fifth in the Brazilian Textile and Apparel Chain Billing Ranking.

In general, empowerment had a positive influence on slow fashion consumption. On the other hand, materialism positively influenced only one orientation toward slow fashion (exclusivity).

As a limitation of the study, the lack of a specific scale to measure consumer empowerment stands out. In addition, the sample was restricted to consumers from Fortaleza, thus results might differ for different locations.

The study provides managerial implications related to how strategies of empowerment can be incorporated by slow fashion companies into their marketing programs, such as more active consumer involvement in product co-creation processes.

This study contributes to the construction of theoretical and empirical knowledge on slow fashion, from its association with constructs such as empowerment and materialism. Furthermore, a conceptual model involving all relations found between the factors of the three constructs has been proposed.
