Abstract
Purpose
The purpose of this paper is to show how to properly use the method of replacement to construct mixed two- and four-level minimum setup split-plot type designs to accommodate the presence of hard-to-assemble parts.
Design/methodology/approach
Split-plot type designs are economical approaches in industrial experimentation. These types of designs are particularly useful for situations involving interchangeable parts with different degrees of assembly difficulties. Methodologies for designing and analyzing such experiments have advanced lately, especially for two-level designs. Practical needs may require the inclusion of factors with more than two levels. Here, the authors consider an experiment to improve the performance of a Baja car including two- and four-level factors.
Findings
The authors find that the direct use of the existing minimum setup maximum aberration (MSMA) catalogs for two-level split-plot type designs may lead to inappropriate designs (e.g. low resolution). The existing method of replacement for searching exclusive sets of the form (α, β, αβ) available in the literature is suitable for completely randomized designs, but it may not provide efficient plans for designs with restricted randomization.
Originality/value
The authors provide a general framework for the practitioners and have extended the algorithm to find out the number of generators and the number of base factor at each stratum, which guide the selection of mixed two-level and four-level MSMA split-plot type designs.

Abstract
This chapter presents the strategy employed to develop a methodology to evaluate research collaboration networks in a higher education context. The research design comprised four successive tracks. We understand these methodological tracks as the tactics employed to organise available means to accomplish an objective. In the first track, we selected the key subjects, the ego networks and the network leaders to be analysed. In the second track, we visualised networks through graphs. In the third track, the statements of the subjects about formed networks were pursued, based on interviews. In the fourth track, case studies were researched and described. The study included qualitative and quantitative data to uncover the interactive processes of doing collaborative research inside a network. The methodology was useful to obtain visual understanding of the networks of co-authorial relations, quantitative and qualitative markers to be used in participatory evaluation of collaborative research networks, as well as an extended view of the life cycles of collaborative research networks. The main contribution of the chapter is to show a sequence of cross-disciplinary methodological steps allowing to understand different types of relations inside research network.

Abstract
Purpose
This study aims to develop a proprietary indicator to measure the digital presence of the institutions: the digital presence index.
Design/methodology/approach
This research delves into how nonprofit institutions, specifically business interest associations (BIAs), have developed their internet presence by applying essential digital marketing techniques. To this end, and using big data mining tools, this study analyzes the tracking by internet users of 102 BIAs, with their respective websites in 36 countries in Europe and the USA. In addition, the presence and activity of the institutions included in this study on social networks are considered.
Findings
This research serves as a basis for discussing the current gap between social reality and the digitalization of institutions. In this sense, conclusions are drawn on the importance of managerial profiles in decision-making on digitization and the necessary knowledge that, together with Web and social network managers, they must have to articulate the means and techniques that promote the internet presence of the organizations they manage.
Originality/value
Conclusions are drawn according to the geographical scope of the BIAs, and an argument is made about the difficulties of connection and loss of prominence of this type of institutions among their different target audiences, especially among the youngest and most digitized.

Abstract
Purpose
Fans are proactive consumers of pop culture products, who can be seen as prosumers. Fanvideo production is one of their most widespread practices in the participatory culture scenario. Thus, the aim of the present study is to analyze how ludic prosumption is featured on plays performed in Brazilian fanvideos based on successful pop culture franchises.
Design/methodology/approach
Research based on the interpretive content analysis of fanvideos of plays produced by Brazilian fans based on five emblematic pop culture franchises and published on YouTube.
Findings
Results have shown six play types in the analyzed fanvideos – i.e. child's play, performing powers, cosplay, play in social rites, teaching to play and “zuêra” –, which revealed a way of having fun in different situations through different practices based on ludic consumption experiences in different spheres of social life.
Originality/value
CCT-based studies focused on investigating plays as ludic consumption phenomenon, as well as fan culture, remain at early research stage. Thus, the main contribution of the present study lies on associating such concepts based on the concept of prosumption.

Abstract
Purpose
This paper aims to contribute to a better understanding of the relationship between the rework cycle with system dynamics (SD) models and the Project Management Institute (PMI) process group.
Design/methodology/approach
To achieve the aim of this paper, 84 articles that blended SD models and project management (PM) were analysed to identify key variables used in PM modelling. The key variables were utilised to build an extended SD model with multiple rework cycles to explain the link between the rework cycle SD model and PMI process group.
Findings
The results show that SD might be a favourable approach to capture the reality of the project life cycle when it is extended to represent front-ending, delivery and back-ending. In fact, SD models could potentially be extended to the agile and hybrid methodologies for improving the PM.
Research limitations/implications
Although this paper provides a better understanding about the extended project life cycle by SD modelling, the results reported herein should be considered in future research that comprises the design of a SD model considering the agile and hybrid methodologies for PM.
Practical implications
This paper shows how the rework cycle can be applied to the extended project life cycle and the PMI process groups. Additionally, it highlights why SD modelling is a crucial tool for assisting managers with long-term decision-making in PM.
Originality/value
This study is among the first to explore the integration of rework cycle SD models within the PMI process groups. Specifically, it may prove valuable in supporting decision-making for project managers at each stage of a project’s extended life cycle. As a result, the research also contributes to the ongoing discussion on integrating PM with sustainability and innovation considerations.
Propósito

Abstract
In the context of American institutions of higher education, the practical implementation of strategies associated with the development of L3+ or multilingual education often remain difficult to implement. Furthermore, students who reach the university level with pre-acquired bi/multilingual and bi/multicultural skills may perceive their competencies as trivialized and undervalued due to the lack of linguistically relevant opportunities available to them.
By contrast, the recent implementation of a multilingual course titled “Intercomprehension of the Romance languages: a pathway to Multilingualism,” at California State University, Long Beach (2014–2018) and St. Lawrence University (2018) offers bi/multilingual students the tools to develop skills geared toward language learning in a continuous effort to appraise, nurture, and upraise the ever-growing linguistic diversity present among students and faculty members in universities across the United States. This course and its iterations specifically benefit students’ pre-existing bi/multilingual competencies while offering them opportunities to reinforce and expand their multilingual repertoire. Students learn how to read in 5+ Romance languages, reinforce their knowledge of English, as well as of their Romance language, all while strengthening their metalinguistic awareness by learning how to navigate a larger repertoire of either foreign or unknown related languages.
In addition to discussing the pedagogical and theoretical framework of the course, the authors propose to explore how this innovative approach favors the development of multilingualism among students in North-American universities by examining course demographic data collected from several of these courses and key results relating certain aspects of students’ initial contact with new languages through intercomprehension.

Abstract
Purpose
Rio de Janeiro has a high tourism potential, and it is the only Brazilian city among the 100 most visited in the world. However, the National Confederation of Commerce of Goods, Services and Tourism estimates that from the total loss of revenue from tourism activities of the State of Rio de Janeiro in 2017, approximately 29 percent of this loss can be attributed to increased violence in the State. Thus, this study aims to estimate the impact of violence on tourist arrivals to Rio de Janeiro.
Design/methodology/approach
The analysis is based on a sample of tourist arrivals to Rio de Janeiro from 51 countries, for the period between 2003 and 2016. Violence is represented by violent deaths in the State of Rio de Janeiro as well as in the capital. The estimates are based on panel data methodology. This study reports fixed-effect estimates as well as dynamic panel data estimates obtained through S-GMM. The study runs regressions for the full sample and also for two other samples: one with tourists coming from developed countries and another with tourists from developing countries.
Findings
The results reveal that violence negatively impacts tourism to Rio, and it shows that tourists from developed countries are more affected by violence than tourists from developing countries. The findings indicate that for each violent death in the capital of Rio de Janeiro, almost four tourists from developed countries and approximately three tourists from developing countries quit going to Rio de Janeiro.
Originality/value
The paper is one of the few to investigate the impacts of urban violence on tourism. The paper provides two contributions. First, it addresses the effect of violent deaths on tourism, bringing evidence to a destination with a high tourism potential, but which suffers from urban violence. Second, the study is the first to investigate whether this relation is different for tourists from countries with distinct levels of development (and thus with different levels of violence).

Abstract
Purpose
A review on additive manufacturing (AM) of shape memory polymer composites (SMPCs) is put forward to highlight the progress made up to date, conduct a critical review and show the limitations and possible improvements in the different research areas within the different AM techniques. The purpose of this study is to identify academic and industrial opportunities.
Design/methodology/approach
This paper introduces the reader to three-dimensional (3 D) and four-dimensional printing of shape memory polymers (SMPs). Specifically, this review centres on manufacturing technologies based on material extrusion, photopolymerization, powder-based and lamination manufacturing processes. AM of SMPC was classified according to the nature of the filler material: particle dispersed, i.e. carbon, metallic and ceramic and long fibre reinforced materials, i.e. carbon fibres. This paper makes a distinction for multi-material printing with SMPs, as multi-functionality and exciting applications can be proposed through this method. Manufacturing strategies and technologies for SMPC are addressed in this review and opportunities in the research are highlighted.
Findings
This paper denotes the existing limitations in the current AM technologies and proposes several directions that will contribute to better use and improvements in the production of additive manufactured SMPC. With advances in AM technologies, gradient changes in material properties can open diverse applications of SMPC. Because of multi-material printing, co-manufacturing sensors to 3D printed smart structures can bring this technology a step closer to obtain full control of the shape memory effect and its characteristics. This paper discusses the novel developments in device and functional part design using SMPC, which should be aided with simple first stage design models followed by complex simulations for iterative and optimized design. A change in paradigm for designing complex structures is still to be made from engineers to exploit the full potential of additive manufactured SMPC structures.
Originality/value
Advances in AM have opened the gateway to the potential design and fabrication of functional parts with SMPs and their composites. There have been many publications and reviews conducted in this area; yet, many mainly focus on SMPs and reserve a small section to SMPC. This paper presents a comprehensive review directed solely on the AM of SMPC while highlighting the research opportunities.
