Abstract
Purpose
The aim of this study is to identify perceptions, attitudes and behavior of young adults concerning wine consumption, using the “theory of planned behavior” as a theoretical framework.
Design/methodology/approach
The aim of this study is to identify perceptions, attitudes and behavior of young adults concerning wine consumption, using the “theory of planned behavior” as a theoretical framework.
Findings
The major findings are that attitudes and subjective norms are, apparently, the components with most influence on behavior of young people in relation to wine consumption. For the consumers group, attitudes seem to be the most crucial component, especially the “interest in alcohol”. They drink it in special occasions for sociability and to disinhibit. Regarding the non-consumers group, the main attitude is “dislike taste”. Also the subjective norms, are very present, especially parents, society, friends and publicity, in consumers group. The non-consumers have the perception of greater parental induction to not consume wine. No significant differences were found between gender or educational system.
Research limitations/implications
Concerning the results, a limited, convenience sample, was employed and this is assumedly an exploratory study. Therefore the results cannot be considered to represent a broad section of the groups studied. Still sample related, only Portuguese young adults students were studied.
Social implications
This research can contribute not only for the knowledge relating to Portugal as a wine consuming environment but also to the general area of attitudes and perceptions of young people towards moderate wine consumption. As today young adults, novice or potential wine consumers will be the next generation of wine consumers, it can be beneficial for wine marketers to focus on this target population aiming at exploring further their engagement with wine.
Originality/value
This research has an originally approach to wine consumption by young adults once it focus and explore the non-problematic behavior of young adults about wine consumption. The results of this study can contribute to the development of targeted advertising and publicity of the wine industry, in order to promote moderate wine consumption among young adults.

Abstract
Purpose
In a printed circuit board assembly (PCBA), the coefficient of thermal expansion (CTE) mismatch between the solder joint materials has a detrimental impact on reliability. The mechanical stresses caused by the thermal changes of the assembly lead to fatigue and sometimes the failure of the solder joints. The purpose of this study is to propose a novel pad design to obtain an interrupted solder/substrate interface, to improve the PCBA reliability.
Design/methodology/approach
An interruption in the continuous intermetallic compound (IMC) layer of a solder joint was implemented, by the deposition of a silicone film in the pad, changing its geometry. That change allows a redistribution of stresses in the most ductile zone of the solder joint, the solder. The stress concentration at the solder/substrate interface is reduced, as well as the general state of stress at the solder joint.
Findings
A new way was developed to reduce the stress on the solder joints, caused by thermal variations, because of the different components CTEs mismatch. This new method consists of interrupting the IMC layers of the solder joint, strategically, redirecting the usual stresses to a more ductile area of the joint, the solder. This is an innovative method that allows increase the lifetime of PCBAs and the equipments.
Originality/value
In this study, a new pad design concept for higher solder joint reliability was developed to reduce the shear stress in the solder joints because of the CTE mismatch between all the solder joint components.

Abstract
Purpose
This study aims to investigate the effect of bismuth addition (up to 30 Wt%) on the microstructure and electrical conductivity of a commercial lead-free alloy (SAC405) near the solder/substrate soldered joint. The system under study is referred in this work as (SAC405 + xBi)/Cu, as Cu is the selected substrate in which the solder was casted. The electrical resistivity of this system was investigated, considering Bi addition effect on the local microstructure and chemical composition gradients within that zone.
Design/methodology/approach
Solder joints between Cu substrate and SAC405 alloy with different levels of Bi were produced. The electrical conductivity along the obtained solder/substrate interface was measured by four-point probe method. The microstructure and chemical compositions were evaluated by scanning electron microscopy/energy dispersive spectroscopy analysis.
Findings
Two different electrical resistivity zones were identified within the solder interface copper substrate/solder alloy. At the first zone (from intermetallic compound [IMC] until approximately 100 μm) the increase of the electrical resistivity is gradual from the substrate to the solder side. This is because of the copper substrate diffusion, which established a chemical composition gradient near the IMC layer. At the second zone, electrical resistivity becomes much higher and is mainly dependent on the Bi content of the solder alloy. In both identified zones, electrical resistivity is affected by its microstructure, which is dependent on Cu and Bi content and solidification characteristics.
Originality/value
A detailed characterization of the solder/substrate zone, in terms of electrical conductivity, was done with the definition of two variation zones. With this knowledge, a better definition of processing parameters and in-service soldered electronic devices behavior can be achieved.

Abstract
Purpose
This paper explains the mechanisms underlying the generation of two-way knowledge spillovers through the interaction of subsidiaries with differentiated local responsibilities and domestic firms.
Design/methodology/approach
The study is based on firm-level panel data from a census of Colombian manufacturing firms for the period 2003–2012. The estimation procedure involves two stages. In the first one, total factor productivity (TFP) of foreign and domestic firms is estimated. In a second step, we estimate conventional spillovers (from foreign-owned to local firms) and reverse spillovers (from local to foreign-owned firms) separately, using a random effect approach.
Findings
This study’s findings reveal that only locally creative subsidiaries enjoy positive and significant two-way knowledge spillover effects. The connectivity of subsidiaries to local and international networks is reinforced by reciprocal relationships among actors that enhance bidirectional knowledge flows, these being favored by the dynamics of clustering effects.
Originality/value
The paper contributes with new empirical evidence about the mechanism explaining how the technological heterogeneity of subsidiaries plays a determinant role in the generation of both knowledge flows from foreign to domestic firms and to the reverse, all integrated into the same framework.

Abstract
Purpose
The purpose of this paper is to develop a new maturity model to identify the current state of maintenance area of organizations and drives actions to increase efficiency and effectiveness toward the concept known as world-class.
Design/methodology/approach
The model was developed based on an extensive literature review on maintenance management and maturity assessment, which allowed identifying the relevant factors in maintenance management and the world-class behaviors for each factor. The progressive maturity levels for each of the identified ten factors form the model. To test its effectiveness, it was applied to the maintenance area of three companies.
Findings
The model application showed that, in addition to being a self-assessment tool, it provides knowledge, to those who use it, on behaviors or practices that enable world-class results. For each factor, potential gaps and the desired state were defined focusing on behaviors rather than on indicators values or adopted methodologies, which facilitates the identification of improvement actions that lead to better performance.
Research limitations/implications
Through its use, maturity levels can be identified for all considered maintenance management factors, however, the overall maturity of the maintenance area is not determined. Although this overall evaluation can be done assigning a weight to each factor, it was not considered an added value for the set purpose.
Originality/value
The proposed maturity model contributes to the understanding of the maintenance management process and how to stand out nowadays in an area that has an increasingly important impact on productivity and quality.

Abstract
It is no longer enough to have a technology base to meet customer needs. The competitiveness of the tourism sector is ensured through the innovation capacity that companies can achieve, either through innovation associated with services or through services. The relationship between tourism innovation and business competitiveness in the tourism sector must consider emerging and innovative technologies that appear daily in society. In this context, the information systems applied to tourism must take into consideration the various sectors of activity: accommodation, travel agencies, restaurants and gastronomy, tourist entertainment, transport, among others. In addition to tourism management information system, it must integrate an innovation mechanism, which should be based on the definition of an appropriate business model. The business model that ensures innovation has to integrate design, production, service, and marketing through a new customer relationship, therefore technology must be able to meet the demands inherent in this new model. The purpose of this chapter is to investigate how the concept of Industry 4.0 can affect the development of tourism in Portugal. In this context, it is relevant for tourism that all companies consider the technological drivers of change associated with the concept of Industry 4.0, constituting a technological basis for leveraging tourism companies to a technological environment called ‘Tourism 4.0’.

Abstract
Purpose
The purpose of this paper is to examine the relationship between sustainable operations practices (SOP) and performance.
Design/methodology/approach
This study was conducted through a systematic literature review followed by a meta-analysis of correlations.
Findings
In the results, 14 of the relationships examined showed a positive relationship and 12 the presence of moderators. The study findings indicate that contingency affects the relationship between SOPs and performance.
Research limitations/implications
The research presented in this paper is mainly limited to databases that were searched. Among the quantitative articles selected from the databases, many did not have the data needed to conduct the meta-analysis, which may have limited the results of this study.
Practical implications
Using the results of this study, practitioners can become aware of to the occurrence of moderating factors in the relationships, which can range from interference from other practices and variables to characteristics of the organization itself or the market in which organizations operate.
Originality/value
This study uses a multidimensional approach for both SOP and performance. This approach allowed a more complete and comprehensive result, showing how these SOPs influence the different categories of performance, expanding the understanding of the relationship between practices and performance.

Abstract
Purpose
The Recovery Self-Assessment (RSA–R) in Revised Version is an instrument designed to assess the degree to which mental health programs and services implement recovery-oriented practices. The purpose of this paper is to conduct a cross-cultural adaptation of the RSA–R instrument for use in local mental health services in the city of Campinas, State of São Paulo, Brazil.
Design/methodology/approach
This method for cross-cultural adaptation of the instrument included a series of iterative steps including preparation, translation, back translation, harmonization, expert evaluation, focus groups, in-depth interviews, expert opinion and pilot study.
Findings
A multi-rater assessment of the equivalence of content between the original RSA–R and the translated version revealed that each of the 32 items achieved at least 88% agreement in terms of equivalency. A multi-step harmonization process revealed additional suggestions for improvements in readability, comprehension and applicability to Brazilian context. An expert in youth and adult education provided additional stylistic recommendations. Combined, this iterative approach to cross-cultural translation resulted in an adapted version of the instrument that was well understood, culturally appropriate and adequate for further verification of psychometric properties.
Originality/value
The recovery process in Brazil and in the USA has culturally determined differences in terms of the way mental disorders are understood, diagnosed and treated. Moreover, there are different notions of what constitutes desirable results of recovery, health care and welfare. At the present time, there are few, if any, available cross-cultural instruments to assess the recovery-orientation of services between Brazil and the USA.

Abstract
The following is an annotated list of materials that discuss the ways in which librarians can provide library users with orientation to facilities and services, and instruct them in library information and computer skills. This is RSR's 11th annual review of this literature, and covers publications from 1984. A few items from 1983 have been included because of their significance, and because they were not available for review last year. Several items were not annotated because the compiler was unable to secure them.
