The purpose of this paper is to investigate, through a comparative analysis, the applicability of lean manufacturing practices, such as value stream mapping (VSM), for productivity improvement in recycling centres (RCs) aided by multi-criteria decision analysis.

The study is carried out in five RCs that sort the municipal solid waste of Porto Alegre, one of the main cities in Brazil. Since all of the centres present their labour composed by poor communities’ members, cultural and social characteristics may represent an incremental challenge for lean implementation. Further, these centres are organised in cooperatives, in which decisions are taken through a participatory way and all their members are entitled to vote, undermining and retarding the decision-making process.

The integration of a multi-criteria decision-making tool to the lean practices enables the prioritisation of improvements, complementing the final stage of VSM. In particular, this contribution becomes especially important in cooperatives managed by community, where decisions are often complex and time-consuming. Finally, despite the increasing pressure for better performance of RCs, the existent mindset is still far from the private sector, where lean practices were conceived. Further, the findings suggest that, despite processes similarities, it is not feasible to declare the existence of a one-best practice to such scenario.

In theoretical terms, the authors demonstrate through a multi-case study the adequacy of analytic hierarchy process as a decision analysis tool complementary to the VSM, enabling a broader perspective about this subject. Concerning the practical contribution, the comprehension of the adaptation needs for lean practices implementation within the production context of solid waste RCs provides a framework with guidelines for this sector, when incorporating lean activities. Lean practitioners and eventual municipal authorities involved in improving productivity of community-managed RCs might benefit from this framework, since they will be able to emphasise the development of recommended and already tested lean practices that tend to improve their operational performance.

The purpose of this paper is to highlight the problems in the measurement of culture in consumer studies and offers suggestions for remedies.

Drawing on literature from related fields, the paper discusses some general issues in the measurement of culture and draws consumer researchers’ attention to the flaws in the common cultural measures in consumer research. Implications for future research are also provided.

The paper highlights two main shortcomings of commonly used culture instruments which are seldom taken into account by consumer researchers. Specifically, the commonly used culture dimensions in consumer studies do not have clear conceptual boundaries. Moreover, important differences between the different approaches to culture measuring (self- vs group-referenced and values vs practices) are always overlooked. The paper suggests that consumer research needs more focussed and refined measures and discusses which approach is better in which context.

This paper explores the issues of conceptual ambiguity and approach inconsistency in order to draw consumer researchers’ attention to the flaws in common measures of culture. Only when one measures what one expects to measure will the relationship that one observe between these cultural dimensions and consumer behavior be valid.

The purpose of this paper is to apply a hybrid algorithm based on the combination of two heuristics inspired by artificial life to the solution of optimization problems.

The flock‐of‐starlings optimization (FSO) and the bacterial chemotaxis algorithm (BCA) were adapted to implement a hybrid and parallel algorithm: the FSO has been powerfully employed for exploring the whole space of solutions, whereas the BCA has been used to refine the FSO‐found solutions, thanks to its better performances in local search.

A good solution of the 8‐th parameters version of the TEAM problem 22 is obtained by using a maximum 200 FSO steps combined with 20 BCA steps. Tests on an analytical function are presented in order to compare FSO, PSO and FSO+BCA algorithms.

The development of an efficient method for the solution of optimization problems, exploiting the different characteristic of the two heuristic approaches.

The paper shows the combination and the interaction of stochastic methods having different exploration properties, which allows new algorithms able to produce effective solutions of multimodal optimization problems, with an acceptable computational cost, to be defined.

Timing constraints affect the manufacturing of traditional large-scale components through the material extrusion technique. Thus, researchers are exploring using many independent and collaborative heads that may work on the same part simultaneously while still producing an appealing final product. The purpose of this paper is to propose a simple and repeatable approach for toolpath planning for gantry-based n independent extrusion heads with effective collision avoidance management.

This research presents an original toolpath planner based on existing slicing software and the traditional structure of G-code files. While the computationally demanding component subdivision task is assigned to computer-aided design and slicing software to build a standard G-code, the proposed algorithm scans the conventional toolpath data file, quickly isolates the instructions of a single extruder and inserts brief pauses between the instructions if the non-priority extruder conflicts with the priority one.

The methodology is validated on two real-life industrial large-scale components using architectures with two and four extruders. The case studies demonstrate the method's effectiveness, reducing printing time considerably without affecting the part quality. A static priority strategy is implemented, where one extruder gets priority over the other using a cascade process. The results of this paper demonstrate that different priority strategies reflect on the printing efficiency by a factor equal to the number of extrusion heads.

To the best of the authors’ knowledge, this is the first study to produce an original methodology to efficiently plan the extrusion heads' trajectories for a collaborative material extrusion architecture.

It has long been known that family firms have a high mortality rate and that increasing these firms' survival rate is one of the most difficult challenges faced by both public policies and scholars. While most policies and researchers have focused on the business side, in recent years, more attention has been paid to the family sphere. This chapter goes one step further by not focusing on one side or another of this binomial, but on the relationship between both. In particular, we analyze the paradoxes emerging between the different inter- and intragenerational dyads that coexist in family firms (mother-daughter, father-son, mother-son, father-daughter, brother-sister, wife-husband, etc.) to open new lines of debate and propose new basis for the establishment of family firms-targeted public politics. We propose policies that will help family decision-makers to manage unique paradoxes that characterize family businesses.

In recent years, international bodies and public opinion have recommended that governments adopt social responsibility practices to inform and be accountable to citizens about their sustainability actions in environmental, social and economic fields (Galera et al., 2014) and restore citizens' confidence in public authorities (Crane et al., 2008; Shepherd et al., 2010). This chapter reviews the literature on measuring and reporting sustainable performance in the public sector. Analyzing 35 studies published in a period of 10 years (from 2012 to 2021), we address two specific research questions: How and to what extent have public organizations changed to integrate sustainability reporting (SR) systems? What are the enabling organizational factors in adopting SR in public organizations?

Roasted coffee provides a complex blend of different flavours which produce a range of sensory qualities. With the development of protocols for the production of fresh juices, jams and marmalades from cocoa and cashew pulp juices at Cocoa Research Institute of Ghana, this paper aims to study the effects of roasted coffee powder on fermented cocoa and cashew juices to diversify the uses of these two juices.

Cocoa and cashew juices were fermented with the incorporation of 2% roasted coffee powder using Saccharomyces cerevisiae yeast starter. The fermenting juices were monitored by measuring pH, temperature, specific gravity and titratable acidity. At the end of the fermentation, the juices were poured into clean, sterilized containers to mature. They were then analysed for their physicochemical, microbiological and sensory qualities. These were repeated with cocoa and cashew juices without coffee powder to determine the effects of the roasted coffee on the fermented juices.

The addition of roasted coffee powder to cocoa and cashew juices did not have any significant effect on the fermentation performance of the juices. Three out of the four juices took a total of 13 days to complete fermentation with an average final specific gravity of 0.99. The quality of the fermented juices was not compromised by microbial activities. However, the addition of roasted coffee powder reduced the alcohol content of fermented cocoa juice from 9.0 to 5.0% and that of cashew from 11.0% to 7.5%. Sensory analysis using untrained panellists, who were ordinary consumers, showed significant differences among the four fermented juices in terms of appearance, taste and aroma. Their mean scores for coffee aroma ranged from 0.3 to 2.0 with coffee incorporated fermented juices having higher rankings.

These findings have shown the possibility of processing cocoa and cashew juices, which under normal circumstances would have been discarded along their value chains, into coffee-flavoured wines. They are also important to cocoa, cashew and coffee farmers, processors, as well as wine enthusiasts.

The purpose of this paper is to investigate whether Hofstede’s (2001) cultural framework and the value paradox explain the use of appeals in advertising in Estonia.

Hypotheses are drawn in relation to Hofstede’s original four cultural dimensions – power distance, masculinity/femininity, individualism/collectivism and uncertainty avoidance. A sample of 110 print advertisements from four magazines were analyzed using Pollay’s (1983) classification of advertising appeals.

The results show that Estonian advertising reflects paradoxical values related to low power distance and femininity dimensions, and culturally congruent values related to high-uncertainty avoidance and individualism.

Findings suggest that cultural values (desired) alone are insufficient to predict the reflection of culture in advertising. Rather, consideration of the discrepancies between the cultural values (desired) and practices (desirable) enables a better explanation of the relationship between society and its advertising.

Scholars have shown increasing interest in the consequences of culture on advertising, but the opposing aspect of cultural values and practices has received limited research attention. The paper offers interesting insights regarding the effect of culture and the value paradox on the use of appeals in advertising. Additionally, analyzing the advertising of Eastern Europe is highly important because of the limited research attention that exists with respect to advertising in the region.
