Is it possible to consider organizational entrenchment (OE) and continued commitment (CC) as the same phenomenon? Are there enough differences between CC and affective commitment (AC) to defend that they cannot be part of the same construct? The objective of this study was to examine the convergence of validated measures between OE and CC and their discrimination to AC. The authors’ aim was to compare two models of antecedents and their consequences: the model that includes OE and AC, and the one that includes CC and AC.

An extensive cross-sectional study was conducted with a sample of 1,648 respondents (the majority lived in the Northeast region of Brazil, worked in private services companies, were female, single, under 35 years old, had, at least, begun college studies and received up to five times the minimum wage). A six-point Likert scale was used in this study. To measure OE, CC and AC, the authors used reduced versions of validated measures. To test the hypotheses, first, the authors used Pearson's correlation analysis and then, structural equation modeling, comparing two models of antecedents and consequences (one including OE and AC, and the other, including CC and AC).

As expected, affective commitment had a positive impact on the desired behavior (intention for commitment, defense, staying), whereas entrenchment and continuance commitment had a negative or non-significant impact on these behaviors. Results show the existence of a conceptual and empirical overlap between organizational entrenchment and continuance commitment and indicate that the continuance dimension is not part of commitment but rather part of organizational entrenchment.

The fact that this is a cross-sectional study sets a limitation on the results, for not allowing greater understanding of the dynamics and the causal direction of relationships. Additionally, it follows the trend of studies in the organizational behavior field of utilizing self-reported data, which results in problems related to perceptual bias (Morrow, 2011).

The practical implications of this study regard a greater clarification on which behaviors are expected from either committed and entrenched workers, and which drivers may lead to each of these bonds. Therefore, a better understanding of the phenomenon contributes to the training of managers and to the design of organizational policies and practices.

The clarity of bonds also allows its application to different contexts beyond business organizations, as a step to reach better understanding of commitment and entrenchment in different settings, economical and national realities.

It is expected that these findings add a higher precision to the research on commitment, thus contributing to the validity of the measures. Given these results and confirmation that OE and CC represent the same bond, it is considered appropriate to designate this type of bond simply as OE. Additionally, the results of this study represent a further argument in favor of prioritizing the AC than CC in research and in management of organizational commitment.

This paper aims to analyse residents’ perceptions of tourism growth in Porto prior to the COVID-19 pandemic, aiming to determine the most appropriate strategies to mitigate negative tourism impacts. Studies on resident perceptions of tourism impacts are still scarce, particularly the ones addressing the topic in the context of Portuguese urban tourism areas.

Data was collected through an online survey, focusing on three categories of impacts: (i) economic, (ii) sociocultural (iii) and spatial-environmental, and the respective mitigation strategies, analysed from the perspective of Porto’s residents. Descriptive and bivariate statistics – T-test and Eta correlation – were used to analyse the collected data.

Respondents who live in the city centre experience specific tourism impacts more negatively, when compared to those living outside the inner-city area. Furthermore, no strong correlation is found between the said impacts and the respective mitigation strategies. However, creating awareness among tourists about acceptable behaviour in shared spaces is the strategy that stands out, as it has a medium correlation with all three impact categories. Most impact-strategy associations are weak, meaning that the defined strategies are not the most case-appropriate, which is something that policymakers should address.

To the best of the author’s/authors’ knowledge, this is the first study to adopt this approach in tackling the negative impacts of rapid tourism growth in Porto.

This paper aims to identify the dynamic capabilities that foster organizational resilience towards sustainability.

The study is a qualitative multi-case study with Brazilian manufacturers of different industries that provides an in-depth exploration of underlying dimensions towards resilience for sustainability.

The results indicate that to develop organizational resilience towards sustainability, both in theory and in practical terms, the actions required are long-term plans, regular meetings, benchmarking, communication between areas and distinct hierarchies, partnerships and eco-efficient actions. Regarding human aspects, the leader’s behaviour and shared culture are the means to encourage, educate and exemplify sustainability for all in the organization.

The study has limitations in the form of a small sample size. The implications indicate a relationship between resilience and dynamic capability for sustainability. In other words, resilience develops organizational, human and technological capabilities for sustainability. Such results can improve the organizational strategy construction methods towards sustainability development.

The study has two practical implications for companies to continue working for sustainability. The first practical implication is the need to work the processes that are aimed at the exchange of information both internally and externally to the organization. It has been seen in managers’ speeches that creating ways to listen to employee suggestions could make important resource-saving discoveries and release waste. Another important source of information for improvement of operations is to listen to civil associations and industry and non-governmental organizations, as well as participate in events, lectures and discussion forums. The second practical implication is the need to work with the human side of the organization; sustainability needs to be a part of the worker’s daily life, and it needs to become common to them of the need to reflect on how to improve sustainability of processes for which they are responsible. To achieve this goal, companies need to work the pillar of cohesion resilience, emphasizing the behaviour of leaders (role models) and organizational culture.

The comparative case analysis shows some practices that are able to induce good environment and provide social and organizational benefits, namely, long-term plans, regular meetings, benchmarking, communication between areas and distinct hierarchies, partnerships, eco-efficient actions, behaviour of leaders and shared culture among members of the organization. These practices are the means to encourage, educate and exemplify sustainability for all in the organization.

The originality of this paper is to bring together two streams of the literature, namely, resilience and dynamic capabilities, in the context of sustainability. Drawing on this approach, the study provides a new conceptual model with empirical evidence of key aspects of resilience for sustainability as an eco-capability.

This study relied on the job demands and resource model to understand employees’ turnover intentions. Recent studies have consistently lent support for the significant association between role ambiguity and turnover intentions; however, only a handful of studies focused on examining the potential mediators in this association. The authors argued that role ambiguity positively influences turnover intentions through affective mechanisms: job involvement and satisfaction.

To test the model, a large sample of working adults participated (N = 505).

Structural equation modeling results showed that role ambiguity, job involvement and job satisfaction were significantly associated with turnover intentions. Moreover, a serial mediation was found among the variables: employees with low levels of role ambiguity tended to report higher job involvement, which further increased their satisfaction with the job and subsequently decreased their turnover intentions.

The cross-sectional design is a limitation.

Practical suggestions regarding how organizations can reduce employee turnover are discussed.

The findings provide support for theory-driven interventions to address developing the intention to stay at work among working adults.

This study aims to assess the effect of water variation on bioethanol production from cassava peels (CP) using Saccharomyces cerevisiae yeast as the ethanologenic agent.

The milled CP was divided into three treatment groups in a small-scale flask experiment where each 20 g CP was subjected to two-stage hydrolysis. Different amount of water was added to the fermentation process of CP. The fermented samples were collected every 24 h for various analyses.

The results of the fermentation revealed that the highest ethanol productivity and fermentation efficiency was obtained at 17.38 ± 0.30% and 0.139 ± 0.003 gL⁻¹ h⁻¹. The study affirmed that ethanol production was increased for the addition of water up to 35% for the CP hydrolysate process.

The finding of this study demonstrates that S. cerevisiae is the key player in industrial ethanol production among a variety of yeasts that produce ethanol through sugar fermentation. In order to design truly sustainable processes, it should be expanded to include a thorough analysis and the gradual scaling-up of this process to an industrial level.

This paper is an original research work dealing with bioethanol production from CP using S. cerevisiae microbe.

To promote access to their services, health-care companies provide various communication channels to their customers (beneficiaries) to enable the receipt of requests, such as authorization for examinations, procedures and hospitalizations. Under the approach of innovation studies, the management of customer relationship channels for health-care companies is characterized as a knowledge-intensive business service (KIBS). The purpose of this study is presenting innovation as a strategy to increase customer service productivity, as well as the monitoring of the quality of the service, the generation of health information for beneficiaries and compliance with the regulation set by the Brazilian National Health Agency (ANS).

The study is characterized as an applied research, as it proposes solutions to problems faced by supplemental health-care companies using the strategy of action research, i.e. an independent, social research with an empirical basis.

The result of this study shows that a computerized health-care system can increase productivity by 21.96%, and it presents an innovative solution for health-care companies to guarantee the process of meeting the demands and requests of their beneficiaries, ensuring the compliance with ANS regulations.

These results can be replicated to other healthcare companies and contribute to those seeking innovation, increased productivity and quality improvements in their services.

This work was also motivated by the lack of lstudies in the areas of health-care companies in Brazil.

This chapter addresses the profession of research management and administration (RMA) in Portugal. It starts with a brief outline of the national research and innovation (R&I) ecosystem that contextualises the development of the profession. The RMA community is characterised and the expectations for the future of the RMA profession are summarised using data collected through a national online survey. It is posited that RMA in Portugal is an emergent career having developed key traits of a profession, namely common interests and practices, a concern with deepening specialised knowledge and skills, the existence of an organised network of practitioners, the offer of academic qualifications and training in the area, and the integration in international RMA communities of practice. Nevertheless, future developments in the European Research Area (ERA) are identified as a critical milestone that will influence the development and formal legislative institutionalisation of the RMA profession in Portugal.

This study aims to analyze the impact of Artificial Intelligence (AI) and Machine Learning (ML) on heritage conservation and preservation, and to identify relevant future research trends, by applying scientometrics.

A total of 1,646 articles, published between 1985 and 2021, concerning research on the application of ML and AI in cultural heritage were collected from the Scopus database and analyzed using bibliometric methodologies.

The findings of this study have shown that although there is a very important increase in academic literature in relation to AI and ML, publications that specifically deal with these issues in relation to cultural heritage and its conservation and preservation are significantly limited.

This study enriches the academic outline by highlighting the limited literature in this context and therefore the need to advance the study of AI and ML as key elements that support heritage researchers and practitioners in conservation and preservation work.

This work proposes a methodology to project future freight demand for all commodity types that begin and end in each geographical region and the amount of freight that moves between all origin and destination pairs. Following the traditional four-step demand forecasting framework, the procedure corresponds to trip generation and trip distribution analysis for interregional freight demand. Using future economic growth factors from macroeconomic and input-output models, the amounts of freight production and attraction in each analysis zone are forecasted and taken as given. Subsequently, an iterative matrix balancing method is applied to determine the estimated freight shipment demand for all origin and destination zone pairs. The proposed algorithm is applied to generate predicted future freight demand within the United States from 2010-2050 in five-year increments based on the national freight demand data from 2007. Four different scenarios are proposed that consider variations in both global economic growth and environmental regulation. This study will assist transportation planners and decision makers in public and private sectors to assess how future freight delivery demand on the national scale considering various future global economic growth and environmental policy scenarios will affect various issues such as air quality and human health problems.

Over the past few decades, the environment for organisations has been frequently described using the acronym VUCA: a volatile, uncertain, complex and ambiguous environment. In spite of the popularity of this acronym, it is not unusual to find some overlap concerning the meaning of those terms, as well as poor definitions of each in the literature. Consequently, the main purpose of this paper was to conduct a systematic literature review to obtain a conceptual map of the components of VUCA and their relationships and to highlight some avenues for future research.

The authors conducted a systematic review of various databases between 1999 and 2021. A total of 833 papers were identified and 26 of them met the inclusion criteria for the current study.

The subsequent analysis revealed several overlaps and relationships between the four terms. Based on this analysis, the authors propose a conceptual map that could serve as a basis for future research and practice.

Because of the exploratory nature of the study and the scarce number of empirical studies, the impact that the use of the VUCA framework has had on businesses could not be addressed.

By clarifying the different components of VUCA and specifying the relationships between them with a comprehensive conceptual map, this paper may contribute to more rigorous empirical research, as well as help managers and executives more effectively deal with turbulent environments.
