A study has been carried out on the relationship between the composition, poling condition and piezoelectric properties of thick film layers. Pastes based on lead‐titanate‐zirconate (PZT) powders, with either PbO or a lead‐alumina‐silicate glass frit as binder, were prepared. Microstructure, electrical and mechanical properties were analysed. Processing and poling conditions modify these properties; then a wide latitude of opportunities is offered in the choice of ferroelectric/piezoelectric characteristics of the layers used as sensing elements for sensors. A pressure sensor was realised where a circular diaphragm of alumina supports two piezoelectric layers obtained by screen printing and firing a PZT/PbO‐based ferroelectric paste. The design and the performance characteristics are described.

Social networking sites (SNS) are enjoying growing popularity and have triggered new ethical issues including risks of deception, social grooming, cyber-bullying and surveillance. This development along with the growing power of SNS providers calls for an investigation of the CSR engagement of SNS companies. The chapter examines to what extent three prominent providers – Google, Facebook and Twitter – fulfill their responsibilities.

The chapter draws heavily on a politicized concept of CSR, namely ‘corporate citizenship’ (Crane, Matten, & Moon, 2008a; Matten & Crane, 2005) and ‘political CSR’ (Scherer & Palazzo, 2007, 2011) and discusses the role SNS providers play in administering citizenship rights. The chapter takes a qualitative case study approach.

Facebook, Twitter and Google have not only made clear commitments to act responsibly, they actually enhance the citizenship status of their users in many ways, e.g. by offering a platform for democracy activists. Deficiencies and contradictions also become visible, e.g. SNS providers inhibit citizenship by failing to provide sufficient privacy protection.

The chapter is limited by its case study approach, but provides valuable insights to an industry with considerable influence. It contributes to CSR research by applying and testing the politicized concept of CSR in the context of SNS providers.

Although SNS have received appraisal as effective tools of CSR communication, there has been little attention to CSR policy and practice of the companies providing social networks. This is unfortunate since the activities of SNS providers directly impact on millions of users worldwide.

To evaluate in the first stage, the efficiency of changing the nature and the length of diols on the properties of perfectly hard sequences polyurethanes (PU). In the second, the thermal properties of a new series of segmented PU with different concentrations of soft sequences were determined.

The synthesis of segmented PU has been realised in two stages known as the pre‐polymer method. Various compositions of PU were obtained by keeping the poly(tetramethylene glycol) – PTMG molecular weights constant, but varying its concentration. The products obtained were characterised by IR, NMR, gel permeation chromatography and studied by differential scanning calorimetry.

The level of phase segregation depends on several parameters, especially the nature of the soft segment and its average molecular weight, nature of the hard sequence and the number of hydrogen bonds established in the PU sequences.

The segmented PU obtained were synthesised from PTMG of number molecular weight 2,000. They could also be synthesised from PTMG of molecular weight 600, 1,000, 2,000, 4,000, etc. The effect of change of PTMG molecular weight on PU properties could also be studied.

Better understanding of the morphology of segmented PU and its effect in the practical domains.

Novel perfectly hard sequences PU have been synthesised and characterised. The effect of soft sequence nature and concentration on the phase segregation in these new series of segmented PU is discussed.

The lack of suitable indicators tailored to manufacturing industries’ needs, particularly to small and medium enterprises (SMEs), has been the major challenge to measure and manage industrial sustainability performance. This paper aims to empirically analyze and select the useful and applicable indicators to measure sustainability performance in the context of SMEs.

A systematic review was carried out to identify potential sustainability indicators from the literature. A questionnaire was designed based on the identified indicators and then pretested with the selected industrial experts, scholars, and researchers to further refine the indicators before data collection from the Italian footwear SMEs. Fuzzy Delphi method with consistency aggregation method was applied to analyze and select the final indicators.

The study’s findings show that the selected indicators emphasized measuring progress toward achieving industrial sustainability goals in terms of increasing financial benefits, reducing costs, improving market competitiveness, improving the effectiveness of resources utilization, and promoting the well-being of employees, customers and the community. In doing so, Italian footwear SMEs can contribute to achieving the Sustainable Development Goals (SDGs) by promoting health and well-being, promoting sustainable economic growth, providing productive employment and decent work, and ensuring responsible consumption and production.

The results of this study have significant social implications in terms of promoting the well-being of employees, customers, and the community.

By providing empirically supported indicators tailored to measure and manage sustainability performance in the context of SMEs, this paper contributes to the existing knowledge in the field of industrial sustainability performance measurement. Furthermore, it links the selected indicators to their respective SDGs to provide policy implications.

Proposes an application of fuzzy set theory to model epidemiological problems. Fuzzy logic has been revealed as a powerful predictive tool in the epidemiology of infectious diseases and some ideas are presented on how this could be done. This work presents an attempt to model the dynamics of rabies among a population of partially vaccinated dogs. This study demonstrates how a dynamical system can be modelled by fuzzy linguistic rules compared to the classical differential equations approach. The results are very encouraging and the approach through a more complex dynamical system is discussed in the final section.

The purpose of this paper is to examine whether family-to-business support acts as a job resource that attenuates the negative effects of work demands on the stress and creativity of women micro-entrepreneurs in the informal sector in Sri Lanka.

Data from 359 women micro-entrepreneurs and their respective case officers in local government were used to test the hypothesized relationship between work demands and their creativity through the mediating mechanism of stress and the moderating effect of family-to-business support on the said relationship.

Work demands reduced creativity through heightening the levels of stress faced by women micro-entrepreneurs. However, family-to-business support reduced the negative influence of work demands on creativity through stress.

Women micro-entrepreneurs should build strong family ties to obtain support from family members. In addition, government training programs that target women micro-entrepreneurs should be extended to include their immediate family members.

This paper contributes to the literature by examining whether family-to-business support buffers the negative effects of work demands for women micro-entrepreneurs in the informal sector. In doing so it makes a theoretical contribution by testing the key tenets of the JD-R model in entrepreneurial settings.

This paper aims to identify and empirically analyze useful and applicable metrics for measuring and managing the sustainability performance of small and medium-sized enterprises (SMEs).

To achieve the objective of the paper, potential metrics were adopted from previous research related to industrial sustainability and an empirical analysis was carried to assess the applicability of the metrics by collecting empirical data from Italian footwear SMEs using a structured questionnaire. The SMEs were selected using a convenience sampling method.

The results of the within-case analysis and the cross-case analysis indicate that the majority of the metrics were found to be useful and applicable to each of the SMEs and across the SMEs, respectively. These metrics emphasized measuring industrial sustainability performance related to financial benefits, costs and market competitiveness for the economic sustainability dimension; resources for the environmental sustainability dimension; and customers, employees and the community for the social sustainability dimension.

Apart from the within-case analysis and cross-case analysis, it was not possible to conduct statistical analysis since a small number of SMEs were accessible to collect empirical data.

The findings of the paper have considerable academic, managerial and policy implications and will provide a theoretical basis for future research on measuring and managing industrial sustainability performance. By providing a set of empirically supported metrics based on the triple bottom line approach (i.e. economic, environmental and social metrics), this paper contributes to the existing knowledge in the field of industrial sustainability performance measurement.

New acrylic and allylic resins were prepared by functionalising perfluoropolyethers chains, which assured peculiar surface properties. Blends having a different amount of the acrylic and of the allylic systems were cured in air by UV irradiation. The cure of the films was found dependent on the ratio between the two resins; the concentration for the obtaining of a film fully cured in air was determined. On the basis of this concentration, a macromer functionalised with the right amount of both the acrylic group and the allylic one was synthesised.

Sectoral brands are umbrella brands created to represent all companies’ products belonging to a country’s economic industry abroad to enhance their export performance. This study aims to explore the development of a sectoral brand model through the optic of the social constructionist perspective. Besides, this study also proposes to apply the model to a sectoral brand case in the business-to-business market.

The authors have developed a systematic qualitative literature review to provide a theoretical basis for the attributes chosen to compose the social constructionist sectoral brand management (SCSBM) model. To apply the model, the authors have conducted a series of 17 in-depth semi-structured interviews with the association’s managers that constitute the sectoral brand development, the director of the branding consultancy firm and specialists on place branding.

The authors present the SCSBM model, highlighting that sectoral branding should be seen as a dynamic and continuous process with the integrated participation of all industry stakeholders. Moreover, the authors have applied the model to the Brazil Fashion System brand.

The main contribution to theory is the link between sectoral brand management and the social constructionist approach, being the first study, to the best of the authors’ knowledge, to propose this connection. SCSBM model extends previous work on sectoral brands by adopting a social constructionist view.

The SCSBM model might contribute to marketing professionals willing to develop sectoral brands across multiple economic sectors and geographies.

The study’s originality lies in developing the first model, which adopts a social constructionist approach to sectoral brands.
