The use of continuous fiber-reinforced filaments improves the mechanical properties obtained with the fused filament fabrication (FFF) process. Yet, there is a lack of simulation tailored tools to assist in the design for additive manufacturing of continuous fiber composites. To build such models, a precise elastic model is required. As the porosity caused by interbead voids remains an important flaw of the process, this paper aims to build an elastic model integrating this aspect.

To study the amount of porosity, which could be a failure initiator, this study proposes a two step periodic homogenization method. The first step concerns the microscopic scale with a unit cell made of fiber and matrix. The second step is at the mesoscopic scale and combines the elastic material of the first step with the interbead voids. The void content has been set as a parameter of the model. The material models predicted with the periodic homogenization were compared with experimental results.

The comparison between periodic homogenization results and tensile test results shows a fair agreement between the experimental results and that of the numerical simulation, whatever the fibers’ orientations are. Moreover, a void content reduction has been observed by increasing the crossing angle from one layer to another. An empiric law giving the porosity according to this crossing angle was created. The model and the law can be further used for design evaluation and optimization of continuous fiber-reinforced FFF.

A new elastic model considering interbead voids and its variation with the crossing angle of the fibers has been built. It can be used in simulation tools to design high performance fused filament fabricated composite parts.

We empirically assessed the antecedents of subjective well-being at work for French permanent employees.

The methodology includes qualitative and quantitative data analyses. In the first phase, interviews elicited the antecedents of subjective well-being at work among permanent French employees. In the second phase, a questionnaire survey was used to confirm the relevance of the antecedents uncovered in the first phase.

We found 14 distinct elements that influence French employees’ subjective well-being at work: corporate culture, job dissonance, relationships with colleagues, achievement, professional development, relationships with superiors, status, workload, perks, feedback, workspace, diversity and pay. Moreover, we identified discrete antecedents for the three components of subjective well-being at work: work achievement and relationships with superiors and colleagues for positive emotions at work, job dissonance and workload for negative emotions at work and organizational culture and professional development for satisfaction with one’s work.

The original contribution of this study is to have unpacked the black box of the antecedents of subjective well-being in the French workplace and to have uncovered discriminant predictors for each of the three components of subjective well-being at work. Furthermore, we specifically linked each of these three components with their most significant antecedents.

The present work involves analytical and experimental investigation of sloshing in a two-dimensional rectangular tank including the effect of porous baffles to control and/or reduce the wave motion in the sloshing tank. The purpose of this study is to assess the analytical solutions of the drag coefficient effect on porous baffles performance to track free surface motion variation in the sloshing tank by comparison with experimental shake table tests under a range of sway excitation.

The linear second-order ordinary differential equations for liquid sloshing in the rectangular tank were solved using Newmark’s beta method and obtained the analytical solutions for liquid sloshing with dual vertical porous baffles of full submergence depths in a sway-oscillated rectangular tank following the methodology similar to Warnitchai and Pinkaew (1998) and Tait (2008).

The porous baffles significantly reduce wave elevation in the varying filled levels of the tank compared to the baffle-free tank under the range of excitation frequencies. It is observed that the Reynolds number-dependent drag coefficient for porous baffles in the tank can significantly reduce the sloshing elevations and is found to be effective to achieve higher damping compared to the porosity-dependent drag coefficient for porous baffles in the sloshing tank. The analytical model’s response to free surface elevation variations in the sloshing tank was compared with the experiment’s test results. The analytical results matched with shake table test results with a quantitative difference near the first resonant frequency.

The scope of the study is limited to porous baffles performance under range sway motion and three different filling levels in the tank. The porous baffle performance includes Reynolds number dependent drag coefficient to explore the damping effect in the sloshing tank.

The porous baffles with low-level porosities in the sloshing tank have many engineering applications where the first resonant mode of sloshing in the tank is more important. The porous baffle drag coefficient is an important parameter to study the baffle’s damping effect in sloshing tanks. Hence, obtained analytical solution for liquid sloshing in the rectangular tank with Reynolds number as well as porosity-dependent drag coefficient (model 1) and porosity-dependent drag coefficient porous baffles (model 2) performance is discussed. The model’s test results were validated using a series of shake table sloshing experiments for three fill levels in the tank with sway motion at various excitation frequencies covering the first four sloshing resonant modes.

Through a systematic literature review, this paper aims to endeavor to present a thorough historical perspective on the evolution of employee-based brand equity (EBBE), offering a comprehensive understanding of its development. The study explores the general model, causes and effects of EBBE, as well as the role of culture, leadership and brand management in building EBBE. The paper proposes an integrative framework to understand the interrelationships between the various dimensions of EBBE and offers practical guidelines for future research and the business world.

The paper uses a systematic literature review approach to analyze and synthesize 30 studies on EBBE retrieved from SCOPUS and Web of Science. The analysis involves a thematic and content-based examination of the literature, which is organized into three thematic groups.

The review highlights the importance of EBBE as a driver of organizational performance and success. The paper identifies the evolution of the major themes, trends and debates in the literature and suggests areas for future research. It underscores the need for more qualitative, multi-level and longitudinal research on EBBE, as well as the exploration of the links between EBBE and other forms of brand equity.

This paper is one of the first systematic literature reviews of EBBE, offering a comprehensive and integrated view of the existing literature since the beginning of this concept. The paper’s originality lies in its proposed integrative framework that captures the interrelationships between the various dimensions of EBBE and provides practical guidelines for future research and the business world.

The goal of this article was to look into the direct and indirect links between corporate social responsibility (CSR) activities and the cost of equity, using real earnings management (REM) as a mediator.

To test the hypotheses, the authors applied linear regressions with panel data using the Thomson Reuters ASSET4 and I/B/E/S database on a sample of 540 European companies selected from the environmental, social and governance (ESG) index over the period 2011–2019.

The results show that REM partially mediates the relationship between CSR practices and the cost of equity in European firms belonging to the ESG index.

Instead of beautifying their business, companies should make efficient managerial and organizational improvements to meet their social duty. Regulators in Europe must strive for tighter enforcement while also attempting to raise public awareness of CSR. CSR can be profitable and helpful for primary stakeholders, according to the research.

Although previous literature has investigated the direct correlation between CSR practices and the cost of equity, the present work focuses on considering the direct and indirect association between CSR and cost of equity through the mediating effect of REM, which has not been widely used in CSR studies so far.

Venture capital (VC) is an essential element in healthy entrepreneurial environments; therefore, many countries in developing entrepreneurial economies support the industry via direct or indirect government interventions. The purpose of this study is to examine through the example of the Hungarian market, whether direct or hybrid state involvement has contributed more to the growth of the invested enterprises. The findings are relevant in the design of government VC schemes and in the contracts mitigating the moral hazards inherent in government funding.

The basis of empirical research is a unique hand-collected database covering Hungarian government-backed VC (GVC) investments. Based on the financial data of investee firms, the authors investigate whether firms financed by hybrid VC involving market participants are able to outperform firms that receive pure public financing using panel regression.

Based on Hungarian evidence, hybrid VC-backed firms generated lower growth and employment than their purely government-backed peers. Both schemes showed meagre innovation activity. The conclusion is that because of the conflict of private and economic policy objectives in hybrid financing, the exposure of hybrid risk capital to moral hazard is higher than that of pure public financing. Private interests in hybrid funds can only improve investment efficiency if they are structured along the lines of market-based independent financial intermediation and the contracts imitate the ones existing amongst limited and general partners in private schemes.

The research covers the data of Hungarian government-backed firms by tracking the full range of 86 investments made in the purely government scheme and 340 firms that received funding in the hybrid scheme. The research focuses on two government initiatives, and the results are influenced by the specific regulation of the programs; therefore, the results cannot be generalized for all government agendas; they are indicative in the designs of the agendas.

There is a limited number of empirical studies investigating the impact of VC in developing markets, especially in the Central and Eastern Europe region. This firm-level research on the impact of public VC can help improve the effectiveness of development policies. By analysing the entirety of investments of a VC program that is near to its completion, the authors provide new insight into the efficiency and prospects of GVC schemes in the region.

The purpose of this study is to highlight the threats related to the utilization of synthetic fibers. Volatile organic compounds, particulates and acid gases are released during the production of polyester and other synthetic textiles. Polyester is problematic solid waste material as it takes centuries to break down and hence causes microplastic pollution. Biodegradable synthetic solutions for the replacement of polyester are a sustainable business marketing these days. The naNia fiber is the breakthrough product and it is claimed a biodegradable, compostable and toxin-free polymer.

In this research, fabric constructed of naNia fiber was dyed with the extract of naturally occurring Lawsonia inermis (henna) plant leaves. The henna dye was extracted in water and ethanol using different methods, and the better extract was selected by the evaluation of ultraviolet-visible spectroscopy and phytochemical analysis. Henna with ethanol extract showed more desirable results hence it was selected to dye naNia fabric. To improve dyeability, premordanting, simultaneous mordanting and postmordanting were done using chitosan, fresh lemon extract and tannic acid, respectively. The dyed fabric samples were subjected to color strength analysis and multiple colorfastness tests.

The colorfastness test has shown good to excellent results. Scanning electron microscope analysis had also shown the attachment of dye molecules to the filaments. This study revealed that henna dye is appropriate to color naNia fiber even without the aid of a mordant.

For the first time, toxicant-free, biodegradable polyester (naNia) is successfully dyed with sustainable and naturally available dyes and mordants.

This study aims to embed anatase, rutile and brookite TiO₂ nanoparticles (NPs) with different crystal phases into cotton fabrics by epoxy silane and to examine the effect of these applications on the photocatalytic and mechanical properties of the fabric.

Different aqueous dispersions which contain anatase, rutile and brookite were prepared at three different concentrations (5%, 10% and 15%). These NPs were embedded in cotton fabrics by using GPTS [(3-glycidyloxypropyl) trimethoxysilane]. Characterization tests were performed by scanning electron microscopy (SEM), Raman and Fourier-transform infrared spectroscopy (FT/IR). Samples were stained with methylene blue (MB) and then exposed to solar light for different periods. Color changes of the samples were examined with a spectrophotometer. Air permeability, abrasion and tear strength tests were applied to all samples.

According to SEM images, the NPs were successfully attached to the cotton fabrics, and epoxy silane coating surrounded the fiber surfaces. The presence of the coating was also confirmed by Raman spectroscopy and FT/IR. The treatments reduced the stainability of the samples. The most effective applications for ensuring photocatalytic activity in cotton fabrics were suspensions as 10% brookite, 10% anatase and 5% anatase, in descending order. The applied coating slightly reduced the samples’ air permeability, and wear and tear strength.

The importance of this study is to determine the optimal crystal phase and its concentration by using epoxy silane to ensure self-cleaning properties on cotton fabrics. The sample treated with 10% brookite is the most approached its original white color by 99.65% as a result of degradation of MB (after 120 min). On the other hand, using the pure rutile with epoxy silane was not suitable for removing MB from the fabric.

Today’s competitive business world presents unanticipated challenges to enterprises worldwide. So, the well-being of the employees may be a sustained competitive edge for corporations in improving employee performance. Positive psychology served as the foundation for this study, investigating the interplay between employee well-being and task performance by incorporating organizational-specific factors like organizational virtuousness (OV) and individual-specific factors such as Psychological Capital (PsyCap).

In total, 639 dyadic responses were gathered from the banking sector, encompassing employees in both private and public banks in India, along with their immediate supervisors. The hypotheses were subsequently examined by applying Structural Equation Modeling (SEM).

OV and PsyCap are considerably associated with the well-being of employees and task performance, according to the findings. Employee well-being mediates the relationships between the perceptions of Organizational Virtuousness (OV) and task performance, as well as between PsyCap and task performance.

The intense competition and series of scandals in Indian banks urge the introduction of some behavioral precautionary measures. Banks need to understand and intervene in positive organizational behavior and help the employees build strong PsyCap to enhance their well-being and task performance to gain a competitive edge.

The present study integrated Positive Organizational Behavior (POB) and Positive Organizational Scholarship (POS) to enhance work performance.

This study aims to examine the role of hospitableness towards refugees, as embraced by local hosts, in engendering positive social outcomes, including fostering favourable attitudes and empathy towards refugees, satisfaction from hosting refugees in private dwellings and advocacy for hosting them.

Rooted in the contact theory and drawing on a hospitality social lens framework, the study uses a mixed-methods approach using a sequential quantitative-qualitative design to understand the interface between hospitableness, attitudes and empathy towards refugees, satisfaction from hosting refugees in private dwellings and advocacy for hosting them. A conceptual model is proposed and tested using 160 valid surveys collected from individuals hosting Ukrainian refugees in Slovakia. SEM-PLS is used to test the proposed model. A total of 25 in-depth interviews with Slovakian individuals hosting refugees in private dwellings were also conducted to explain and further explore the initial quantitative results.

The findings indicate that hospitableness has a positive effect on attitudes towards refugees, fosters a sense of empathy and results in satisfaction from hosting refugees. Interestingly, while hospitableness per se does not directly affect advocacy for hosting refugees, it does so indirectly via favourable attitudes towards refugees and satisfaction from the hosting experience. While qualitative findings largely support and further explain the quantitative results, interesting insights are also obtained.

The study advocates that hospitableness should be addressed through a social lens beyond its traditional commercial boundaries. Several implications for policymakers, NGOs and other stakeholders involved in hosting refugees are proposed. Overall, policies need to be oriented towards harnessing the power of refugee hosting schemes, thus increasing the role of hospitableness in addressing societal challenges such as the refugee crisis.

While not new, private hosting of refugees has recently gained momentum following the outbreak of the Ukrainian refugee crisis. In spite of some valuable research delving into hosting experiences from the refugees’ and hosts’ perspectives, this research stream is notably fragmented and largely exploratory. Specifically, there seems to be no comprehensive understanding of how hospitableness towards refugees, as embraced by hosts, can engender positive social outcomes, including fostering favourable attitudes and empathy towards refugees, satisfaction from hosting refugees and advocacy for hosting refugees in private dwellings. Overall, hospitality research is notably biased towards commercial settings, focusing on instrumental benefits rather than societal outcomes. This study focuses on the societal outcomes of hospitableness as a tool to address the refugee crisis.
