The purpose of this study is to develop models and analyse the influence of supply chain governance (SCG) and its conceptions (contractual, relational and transactional) on supply chain performance (SCP).

Multiple case studies and survey methods were used. Data collection in the multiple case studies was performed by in-depth interviews with supply chain executives from top strategic levels in six companies. The research instrument was applied to 185 executives from large companies that possessed a broad, complex supply chain in Brazil.

It was identified that SCG, comprising contractual, relational and transactional aspects, has a positive influence on operational and financial SCP. SCG was found to be a more comprehensive view of the supply chain that focuses on more strategic aspects and long-term inter-organizational relationships. SCG affects SCP, primarily in the operational aspects with regard to global costs and in the financial aspects of investment return.

SCG is a topic that has been widely studied in recent years for analysing inter-organizational relations as a multi-dimensional phenomenon embedded in the company’s structures and processes. Studies analysing all aspects of SCG at the same time, however, have not been found. Moreover, there are a number of performance indicators, but there is a lack of consensus on what determines the performance of these supply chains. Furthermore, few studies have attempted to understand the effects of SCG on supply chain performance.

The purpose of this paper is to present a systematic framework with a meta-analytical approach to find various types of antecedents, consequences and moderation effects of the technological acceptance model (TAM) in banking contexts.

The authors conducted a meta-analysis of a total of 142 articles, which generated 636 observations, in an accumulated sample of 45,781 respondents.

The findings of this meta-analysis demonstrated 18 constructs that were antecedent to the TAM and four constructs that functioned as consequences. Most of these relationships were significant and consistent. The authors also found some methodological, cultural, economic and theoretical moderations effects between TAM constructs and the attitudes/behavioural intentions of banking technological devices.

This meta-analysis reviewed the relationships found worldwide in the literature on TAM constructs in banking contexts. It was possible to identify new avenues for future research. Some specific limitations, such as the non-use of qualitative studies and the clipping of adverse concepts, exist in the secondary data and should be registered.

The work could assist managers in decision-making because the findings resulting from the meta-analysis are more consistent than those from traditional primary surveys.

This research tested the impact of the antecedents, consequences and moderators of the TAM in the banking sector and presented important results via a meta-analytical review. This meta-analysis contributes to the marketing literature by offering a set of empirical generalisations, including relationship coefficients and calculated fail-safe numbers.

The purpose of this paper is to analyze some Brazilian companies’ use of the information technology portfolio management (ITPM) technique as an aid to their information technology (IT) investments management.

It was carried out in five case studies in different Brazilian companies from several economic sectors which were using ITPM or were in the initial implementation phase. Eight interviews were conducted. The persons interviewed were high-level executives working in the IT department in the studied companies.

Different levels of ITPM use was found with respect to IT investment management (planning, control and evaluation). It was observed, in the analyzed cases, that ITPM is used most frequently in IT investment planning, which is the process most discussed and used in analyzed companies. The ITPM technique is used more frequently in Company 2 than in the other cases because the organization of the IT area in the company is structured according to ITPM dimensions.

The ITPM technique has received little attention in IT research and research in this area identifying the use and applicability of ITPM in companies is still very limited in the information systems literature.

The paper presents IT investment management in different Brazilian companies and how ITPM was used to help companies in this process compose by planning, control and evaluation.
