Abstract

Purpose

The current analysis was conducted to investigate the quality of surfaces and geometry of tracks printed using PolyMideTM CoPA, PolymaxTM PC and PolyMideTM PA6-CF materials through fused deposition modelling (FDM). This study also examined the degree of fusion of adjacent filaments (tracks) to approximate the optimal process parameters of the three materials.

Design/methodology/approach

Images of fused adjacent filaments were acquired using scanning electron microscopy (SEM), after which, they were analysed using Image J Software and Minitab Software to determine the optimal process parameters.

Findings

The optimal process parameters for PolyMideTM CoPA are 0.25 mm, 40 mm/s, −0.10 mm, 255°C and 0.50 mm for layer thickness, printing speed, hatch spacing, extrusion temperature and extrusion width, respectively. It was also concluded that the optimal process parameters for PolymaxTM PC are 0.30 mm, 40 mm/s, 0.00 mm, 260°C and 0.6 mm for layer thickness, printing speed, hatch spacing, extrusion temperature and extrusion width, respectively.

Research limitations/implications

It was difficult to separate tracks printed using PolyMideTM PA6-CF from the support structure, making it impossible to examine and determine their degree of fusion using SEM.

Social implications

The study provides more knowledge on FDM, which is one of the leading additive manufacturing technology for polymers. The information provided in this study helps in continued uptake of the technique, which can help create job opportunities, especially among the youth and young engineers.

Originality/value

This study proposes a new and a more accurate method for optimising process parameters of FDM at meso-scale level.

Abstract

Environmental, Social and Governance (ESG) reporting is crucial for organizations, especially in the current era where sustainability holds significant importance. Proper utilization of ESG reporting offers long-term benefits and enhances overall corporate well-being. This study explores fundamental aspects of ESG reporting, elucidating the reporting process, its advantages and requirements. An analysis highlights key impacts on businesses and their influence on consumer behaviour. The disclosure of ESG reporting and its determinants, such as business size and profitability, is discussed. Additionally, the study underscores the role of promoting diversity and inclusion as a Corporate Social Responsibility (CSR) function. Global firms undertake diverse initiatives to advance sustainability. The study emphasizes the triple bottom line theory as a strategy for sustainable development. ESG is recognized as a valuable tool for ensuring sustained growth and development in businesses. The research underscores the imperative for businesses to adopt sustainable measures consistently. Overall, the findings stress the significance of ESG reporting in the contemporary business landscape, linking it to corporate success, responsibility and the pursuit of sustainable practices.

Abstract

This chapter aims to identify the current challenges facing women entrepreneurs. Female entrepreneurship must be analyzed from a binary perspective: the position of women in society and the role of entrepreneurship in society. The study focused on women entrepreneurs in the European Union (EU). Considering the social-economic diversity in the EU, we evaluated the five economic systems. To highlight how these differences are manifested in the different systems, we considered for analysis one country belonging to each model, namely, Denmark for the Scandinavian system, Germany for the Continental system, Ireland for the Anglo-Saxon system, Spain for the Mediterranean System, and Romania, for the Catching-up system. The analysis considered women entrepreneurs in the labor market, female employment/management in the labor market, female entrepreneurs in the labor market, and female mentality regarding work and entrepreneurship.

Abstract

Dark (Netflix, 2017–2020) is a German-produced science fiction television series, created by Baran bo Odar and Jantje Friese. Set in the geographically ambiguous small town of Winden, Dark is an intricate time-travel saga primarily across different epochs. With its emphasis on uncanny natural settings and fairy tale tropes (such as lost children, mysterious travelers, magical devices, etc.), Dark can easily be interpreted as fairy tale. Central is young Jonas Kahnwald who loses his father and witnesses the mysterious disappearance of a local boy. These traumas lead to shocking truths about his heritage. Jonas is the hero (both victim and seeker, after Propp's definition) though his twisting quest brings him face-to-face with two older versions of himself: The middle-aged Jonas fulfils a mentor/donor role for the younger but is conflicted in his desires to both perpetuate and unpick ‘the knot’. Later, Jonas encounters cataclysmic extremist ‘Adam’, a mature version of himself who acts as antagonist. Thusly, Dark centres White male trauma, agency, and ego to reflect responses to historic cultural trauma (such as the notion of the ‘anti-Heimat’) whilst also critiquing traditional conceptions of masculinity through young Jonas's actions. This chapter maps the interplay and representation of ego and trauma. Through textual analysis and with reference to relevant cultural, psychological, and philosophical scholarship, my exploration follows the threads of what Dark communicates about contemporary German masculinity in the face of trauma and how it reflects Western, White cultural thinking about the self.

Abstract

Purpose

Drawing from social exchange theory and a collectivist cultural framework, this study explores the relationship between ethical work climate and organizational citizenship behavior, considering power distance as a potential moderator.

Design/methodology/approach

The study used standard scales to obtain data from 244 employees working in various private companies in India. Structural equation modeling was adopted to test the hypotheses using Analysis of Moment Structures (AMOS).

Findings

The study results show a significant relationship between ethical climate and organizational citizenship behavior. Ethical work climate influences power distance negatively. However, the results also show that power distance does not serve as a moderator between ethical work climate and organizational citizenship behavior.

Practical implications

Corporate leaders often expect employees to demonstrate organizational citizenship behavior, which is aimed at advancing the organization’s interests and outcomes. This study underscores the necessity for expanding the organizational vision to enhance the ethical work climate. Such an initiative not only promotes improved organizational citizenship behavior but also helps to reduce employees' perceptions of power distance within the organization.

Originality/value

Amid extensive literature rooted in individualistic cultures, our study explores the relationship between ethical work climate and organizational citizenship behavior within a collectivist context. This research uniquely introduces the moderating role of power distance, offering new and distinct insights into this dynamic.
