Abstract
Microbiologically induced corrosion of copper intrauterine devices “TCu380A” and “Nova T” by Enterobacter sp. in a synthetic intrauterine medium was investigated. The corrosion behaviour was evaluated applying cyclic voltammetry and Tafel Polarization. The surface morphology was determined using scanning electron microscopy, the corrosion products were analyzed using energy dispersive X‐rays and the biofilm composition was examined by Fourier transform infrared spectroscopy with an attenuated total reflectance device.

Abstract
A corrosion study of the intra‐uterine device, “TCu 380 A”, was made using cyclic voltammetry (CV), scanning electron microscopy (SEM) and optical microscopy (OM). Blood plasma, whole blood and artificial uterine fluid were used as corrosive media in order to establish a comparative scheme of the corrosion behaviour of copper in the device. In summary, the results obtained were not only similar to work reported previously, but also provided complementary data for a better understanding of the corrosion problem.

Abstract
Purpose
The aim of this work is to study the corrosion and scaling factors, mechanisms and processes affecting the materials, equipment and installations of the Cerro Prieto geothermal field (GTF).
Design/methodology/approach
The physicochemical characteristics of the geothermal well and fluids were analysed, recorded and related to the corrosion and scaling phenomena.
Findings
The high temperature and salinity of the steam‐brine mixture and the presence of hydrogen sulphide and carbon dioxide impart a severe level of corrosivity.
Originality/value
Corrosion and scaling control assure an efficient production regime, provide for the durability of the GTF engineering materials and equipment and contribute to environmental quality.

Abstract
Purpose
The purpose of this paper is to dissect the diffusion of the number of organizations that implemented multiple management systems (MSs), considering the International Organization for Standardization (ISO) 9001, ISO 14001 and OHSAS 18001 standards (quality, environment and safety) in the South European countries: Italy, Portugal and Spain. In addition, based on the data collected, forecasting models were developed to assess at which extent the multiple certifications are expected to occur in each studied country.
Design/methodology/approach
Data concerning the evolution of the amount of multiple MSs in Italy, Portugal and Spain were collected for the period between 1999 and 2015. The behavior of the evolution of the number of MSs over the years was studied adopting both the Gompertz and the Logistic models. The results obtained with these two models were compared and analyzed to provide a forecast for the next years.
Findings
The diffusion throughout the years of the number of MSs presents an S-shaped behavior. The evolution of the amount of MSs in countries with a lower saturation level are properly fitted by the Gompertz model whereas the Logistic model fits more accurately when considering countries with a larger saturation level.
Research limitations/implications
The data related to the early years are not available in some of the countries. To overcome this shortcoming missing data were extrapolated from the data set provided by the annual ISO survey. Additionally, the integration level attained by each company was not assessed and, on this regard and in the scope of this paper, an integrated management system is understood as implemented when organizations have multiple MSs implemented.
Practical implications
The results provide a cross-sectional portrayal of the diffusion of MSs certifications in the South European countries and enable a forecast for the trend in the next years.
Originality/value
This study aims for the first time, to the best of the authors’ knowledge, to analyze the diffusion of multiple MSs throughout the years.

Abstract
The purpose of this article is to provide organized, synthesized information related to initiatives throughout the world based on knowledge‐based development (KBD) such as knowledge cities (KCs), knowledge regions, and knowledge countries. A first search was conducted using the Internet and specialized databases under the keywords “knowledge cities”. The information compiled led to other related keywords which branched out the search. All resulting information was then collated and integrated into a number of categories all unified under the field of knowledge‐based development. A compilation of information on the topic “knowledge cities” and other topics related to knowledge‐based development. The information is presented in eight sections: a glossary of KC‐related terms, a list of knowledge‐based development initiatives, a list of associations and organizations related to the topic, a list of urban KBD‐related value dimensions and their indicators, a list of international rankings, a list of special editions on KCs, a bibliography, and a directory of related sites on the Internet. This effort resulted in a public service available at the World Wide Web. The information included in this compilation is limited mainly to public domain information available throughout Internet in both English and Spanish, as well as in selected databases.

Abstract
Purpose
This study aims to improve our understanding of violence, focusing on the analysis of the relation between socioeconomic factors and homicide rates from 2005 to 2019 in Brazilian capitals.
Design/methodology/approach
Multilevel Poisson models were used to estimate the homicide risk in men and women. The response variable was the homicide rate. Fixed effects were estimated for age group, year and gross domestic product (GDP).
Findings
The average homicide rate over the 2005–2019 period was 5.83/100,000 and 83.72/100,000 for women and men, respectively. In both sexes, the homicide rates increased over the period. The highest mortality rates were observed in North and Northeastern capitals. The peak homicide rates were 2010–2014, the risk of homicide decreased as age increased, and the capitals with GDP lower than US$5,000 showed a greater homicide rate.
Originality/value
Brazil remains among the countries with the highest risk of homicide, especially in the north and northeast regions, where socioeconomic conditions are more unfavorable. The improvement of socioeconomic conditions may contribute to changing this situation.

Abstract
The purpose of this chapter is to illustrate the contribution made by migrants in the territory that hosts them, particularly when they transfer their knowledge to members of the community. In the specific case of the sea urchin fishery, it is described how the Morishita family in Baja California undertakes the sea urchin value chain, from the location of population banks to the commercialization of the product in the Japanese market and, by therefore, the promotion of development in rural places while starting a culture of export and currency generation. An adventure of opportunities that has been successful for more than 50 years, whose origin is the sustainable use of “a plague” that today is a delicacy for many.

Abstract
Clusters have basically been conceptualised as a concentration of firms that prosper on the basis of their interaction. However, the classical cluster concept is developing in a more cultural perspective. The so‐called Knowledge Society and the development of information and telecommunications technologies have opened the playing field. New countries and regions can thus meaningfully reduce their distance with respect to other leading regions, provided they create a structure to acquire and disseminate knowledge. This emerging concept also offers more possibilities to be used by all the types of regions in different circumstances, including developing countries. The basic tool for beginning this learning capability will be the creation of a co‐operation structure such as a cluster, including all actors of the innovation system in a country or region. They can be called knowledge clusters: the knowledge cluster in the Basque Country is one of these experiences.

Abstract
Purpose
The main aim of this paper is to demonstrate that “volunteer” employees’ perception of dimensions of intellectual capital (IC) – human, structural and relation capital – creates a motivational environment to enhance knowledge-sharing intention (KSI) and stimulates “volunteer” employee engagement (VEE). The model is applied on the non-profit organizations (NPOs) sector that base their path on sharing values with volunteers and employees in relation to which they have to implement engagement strategies that are beneficial to both developing and deploying individual and organizational human capital.
Design/methodology/approach
To verify the existence of relationships between the constructs of IC, KSI and VEE a partial least squares structural equation model on a sample of 300 “volunteer” employees of NPOs was tested to verify the research hypotheses, as this could explain the causal relationships.
Findings
The results confirm that KSI is positively and directly influenced by the favourable environment resulting from the motivations below the dimensions of IC. The improvement of KSI, determined by IC, has a positive effect on VEE.
Research limitations/implications
Despite the limitation created by the peculiarities of NPOs and the role of volunteers, this paper suggests a strategic approach that the management could implement to create an environment based on the exchange of knowledge and to increase engagement in the value co-creation process.
Originality/value
The ability of a company to adopt sharing strategies depends on the existence of an environment in which individuals are willing to exchange knowledge realizing mutual benefits. The work broadens this perspective by providing governance with a behavioural model that creates a direct relationship between IC, KSI and VEE.
