Abstract

Lamellar micaceous iron oxide paints are successfully employed to provide longlife corrosion protection for metallic structures when exposed to highly aggressive environments. The aim of this work was to formulate and manufacture lamellar micaceous iron oxide paints, able to be used on the protection of steel structures exposed to water. Several formulation and manufacture variables were taken into account. Many paint films fail when they are saturated with moisture and blistering is a common failure because primers usually are not designed to allow the liquid to dissipate back out through the film. Consequently the film can not resist the formation of projections which result in local adhesion loss. For maximum durability, primers must be properly formulated and manufactured. Film permeability, which depends on paint composition (pigment volume concentration) and micaceous iron oxide dispersion time, seems to be the key characteristic controlling subsequent coating performance. Laboratory results indicated that lamellar micaceous iron oxide is a pigment which provides an anticorrosive action by providing a barrier effect. Film permeability must be compatible so as to attain a satisfactory rusting and blistering resistance.

Abstract

The current size of individual particles in most pigments is usually below 1μm; this ensures powerful forces of attraction causing the particles to cling to one another forming aggregates. If pigment dispersion stability is not appropriate, particles join again and form flocculates. It is important to know the initial degree of dispersion, its evolution during coating storage and the influence on its dry film anticorrosive properties. Several anticorrosive coatings were formulated starting from an epoxy resin as binder, tin tannates as inhibitor and a red iron oxide‐micronised talc mixture as inert pigment. Variables studied were pigment dispersion time and coating ageing time in storage. The degree of dispersion was determined by optical photomicroscopy to establish the shape and size of associated particles present in the system. The flow properties of anticorrosive coatings due to the different dispersion degree were evaluated through rheological tests. Coating film behaviour was also assessed for several dispersion times and ageing periods in laboratory, employing a salt spray (fog) cabinet and a 100 per cent relative humidity chamber.

Abstract

Purpose

This study aims to investigate the risks associated with managing the dispersed knowledge in inter-organizational arrangements for innovation. Specifically, it proposes a model to analyze the knowledge management risks in open innovation, applied in four steps.

Design/methodology/approach

Initially, the authors carried out a systematic literature review (SLR) on the concepts that connect knowledge management, inter-organizational arrangements for innovation and risks. The SLR results led to a complementary theoretical review on the conceptual elements in question. Based on the findings, the authors have developed a model to analyze the knowledge management risks in open innovation, which was validated by experts. It was then studied the case of GOL Airlines, a company that uses innovation to overcome the paradox between low-cost and full service in the commercial air transportation industry, considering the application and adjustment of the proposed model.

Findings

Open innovation is one of the inter-organizational arrangement types most applied in the context of innovation. Relations between agents are the primary sources of risks when managing the dispersed knowledge in these arrangements. The authors have found five main risks associated, namely, risk of the innovative effort does not reach the expected objective, risk of knowledge transfer being ineffective, risk of misappropriation of value, risk of dependency (lock-in) and risk of relations.

Practical implications

The practical implication is the proposition of a procedure for applying the model to analyze the knowledge management risks in open innovation, which makes it a prescriptive model for identifying risks. The proposed model is described in four steps, namely, to identify the agents in the environment of the value of open innovation; to identify the types of relations of each agent; to consider the barriers to knowledge management in innovation; and to assess the risks considering the possibilities derived from the agents, their relationships and the barriers. The model is applied in the GOL case and the results are presented.

Originality/value

First, it uses a novel approach to investigate open innovation while studying its risks. This approach considers the knowledge is dispersed and flows from one organization to another through a combination of relations inside the environment of value where the open innovation materializes. Second, it contributes to theory development by opening a research front that fuses four areas: risk management, knowledge management, innovation and inter-organizational arrangements. Third, this paper proposes a theoretical model and presents its operationalization. The study aims to make an impact beyond academia and uses a case study to illustrate the model application in a real and interesting open innovation project to support the business model at GOL Airlines.

Abstract

Purpose

The purpose of this paper is to investigate how knowledge management and university-industry-government collaboration – including the triple helix – relate with each other in influencing organizations’ performance. In the competitive environment nowadays, an organization’s ability to create and use knowledge becomes ever more essential in the search for sustainable competitive advantage, even leading to the search for new forms of inter-organizational arrangements.

Design/methodology/approach

The representatives of such collaborations selected for this study are the National Institutes of Science and Technology. The categorical content analysis technique was used for the qualitative analysis of the data.

Findings

The principal contribution was the proposal of an analytical model relating the knowledge management and triple helix theories and the proposed dimensions (namely, structural, relational, cognitive and the context), considering the peculiarities of the Brazilian context. The findings show that the organizational structure (structural) influences not only the relationship among members (relational) but also the flow of knowledge (cognitive), as well as how relational elements (collaborative culture, trust and leadership) facilitate knowledge sharing. Moreover, the context affects these three other dimensions. The main obstacles identified were cultural differences, bureaucracy and the socio-economic reality, while facilitators were the existence of technology parks and incubators, government incentives and geographical proximity between universities and industry.

Originality/value

This topic was chosen as there are few empirical studies that comprehensively relate the topics of knowledge management and university-industry-government cooperation focusing on the Brazilian context.

Abstract

Purpose

Considering the cognitive challenges associated with a data-rich business environment, this research aims to investigate the relationship between data literacy (DL), perceived data overload (PDO), and technostress (TS), besides the effect of these constructs on professional's individual performance (IP).

Design/methodology/approach

Through survey research, the authors collected data from 321 professionals who work in data-rich and highly technological business environments. To test the hypotheses proposed, the authors developed the partial least squares structural equation modeling (PLS-SEM) procedures.

Findings

The results showed that DL is positively associated with IP and negatively with PDO. PDO is positively associated with TS and negatively with IP. The authors found no significant negative association between TS and IP.

Research limitations/implications

With this research, the authors seek to contribute to the gap in the literature concerning two cognitive challenges associated with data-rich business environments: PDO and TS, analyzing from the point of view of the individual, and highlighting the importance of DL in this context.

Practical implications

The results can assist managers in effectively being concerned with the DL level of their workforce. This is important considering not only the professionals' IP but also the cognitive challenges such as PDO and TS.

Originality/value

The innovation of this study lies in the empirical analysis of DL in the business context and its relationship with two cognitive challenges inherent in data-rich environments: PDO, and TS. Besides, the authors highlight the importance of understanding such phenomena in terms of IP.

Abstract

Purpose

The purpose of this paper is to investigate how certain characteristics of the university–industry–government collaboration facilitate knowledge creation and management, hence innovation focusing on particularities of the Brazilian scenario.

Design/methodology/approach

As a conceptual basis, there are correlations between theories of knowledge management and the Triple Helix, a model referenced to university–industry–government cooperation. The research was conducted through a multiple case study at two National Institutes of Science and Technology (INCTs in Portuguese).

Findings

The main results show the importance of participation in the INCT program, as it enables the creation of an organizational structure with the coordinator’s leadership, who directs the flow of knowledge among organizations and stimulates innovation.

Originality/value

The choice of the topic is justified by the lack of studies on the identification and analyses of the main aspects of this type of collaboration in an integrated way.

Abstract

Drawing upon resource-based view (RBV) and attribution theoretical lenses, this chapter provides a paradigm for examining the interplay among environmental investment towards green innovation, environmental disclosure as well as firm performance using the structural equation modelling (SEM) methodology. This chapter demonstrate a growing environmental awareness among stakeholders of the relevance of environmental performance to share value. It is also suggested that the mediating power of environmental disclosure between environmental investment and firm value as well as incremental goodwill is crucial. The findings of this chapter provide critical implications for several stakeholders that if environmental performance is hypothesised to affect the firm's value, companies may take proactive measures to avert potential environmental-related violations. Besides, investors may trade based on the evidence as to how firm value and its goodwill from acquisition will be affected by news of its environmental performance.

Abstract

Purpose

The purpose of this study is to examine the effects of ownership structure on merger and acquisition (M&A) decisions of Brazilian listed companies.

Design/methodology/approach

This paper is an applied and explanatory research based on secondary data. The sample is comprises non-financial companies listed on the BM&FBovespa between 1998 and 2007. Considering that the dependent variable is binary, the authors estimate panel data logistic regression models. Considering the existence of conflicts of interest among those who have the decision-making power and the supplier of capital for M&A transactions, they draw upon the Agency Theory to develop the theoretical hypotheses.

Findings

The results show that, for a sample of Brazilian non-financial companies listed on the BM&FBovespa (B3), from 1998 to 2007, Brazilian firms present, on average, a highly concentrated ownership structure and the major controlling shareholders are families or the State. These characteristics are negatively related to the likelihood of M&A transactions, as most of these controlling shareholders are reluctant to adopt mechanisms that reduce their control.

Research limitations/implications

With regard to the limitations, this study considered only the M&A definitions as stated by the Bureau van Dijk database. In this sense, future studies may analyze the effects of ownership structure based on other M&A definitions and typologies. In addition, the study is limited to the period from 1998 to 2007, which is prior to the international financial crisis. Future studies may extend the analysis period to include the post-crisis period (2008) to check if there are differences in M&A strategies before and after the crisis.

Practical implications

From a managerial perspective, the results show that minority shareholders have little or no influence over an M&A decision, so they cannot decide on the use of resources for fast growth and access to new markets through M&A. Thus, the investment decision must take into account the nature and the quality of the controlling shareholder.

Social implications

This study shows a significant and negative effect of ownership concentration on the likelihood of M&A transactions. In part, this result demonstrates the importance of understanding the behavior of controlling shareholders before inferring on other key aspects that the M&A literature tends to make fundamental in explaining M&A decisions in publicly traded companies, particularly, in an environment of low minority shareholder protection.

Originality/value

Previous studies have partly found that the M&A decision is motivated by individual advantages obtained from increasing the size of the firm, or from managerial hubris. The results show that these hypotheses do not hold in the Brazilian context. Moreover, the results indicate that M&A decisions are associated with the characteristics of the controlling shareholder, their level of ownership concentration and their typology, contributing to the agency debate on whether the incentive or the entrenchment effect prevails in the context of the agency problem between controlling and minority shareholders, particularly, in an institutional environment of low shareholder protection.

Abstract

Purpose

This paper aims to propose that firms located in science and technology parks (STP) developing corporate social responsibility practices can attract talented workers as an effective knowledge management spillover mechanism.

Design/methodology/approach

A longitudinal study has been carried out from the Spanish Panel of Technological Innovation database (PITEC). The statistical method used for data treatment has been a logistic regression for panel data.

Findings

Empirical results show a positive moderating effect of corporate social responsibility practices on the relationship between the firm’s belonging to a STP and talent attraction.

Originality/value

This research follows previous claim for additional research on the phenomenon of talent management and clusters and STP. In that sense, and to the best of the authors’ knowledge, there is no previous empirical research about the complementarily effect of corporate social responsibility practices and the belonging to a STP in talent attraction.
