This paper aims to present a monitoring system and the usage of a robotic arm to remove finished parts of a three-dimensional (3D) printer build plate, enabling 3D printers to continuously build a sequence of parts.

The system relies on a 2-degree of freedom planar manipulator. The moment to remove printed parts from the printer build plate can be determined based on direct communication with the 3D printer control software or using information from a computer vision system that applies background subtraction and Speeded up Robust Features methods.

The proposed system automatically detects the end of standard 3D print jobs and controls the robotic arm to remove the part.

Lighting variation can deteriorate the response of the computer vision system, which can be minimized using a controlled illumination environment. In addition, the printer build plate edges must be free so the parts can slip off the printer build plate when the robot pushes them out.

The system enables a more practical and automatized usage of 3D printers, reducing the need of human operators.

The proposed system can reduce work hours of laboratory personnel, as there is no need to remove the printed parts manually before another job starts.

Computer vision system monitors the printing process and the automation system that enables continuous sequential 3D printing of parts. A prototype is described, which can be easily replicated with low cost parts.

This chapter examines the professional identities of Brazilian journalists. It does so through an analysis of the growing professional autonomy of journalism from 1950 to 1990 through the life stories of 10 intellectual-journalists, individuals whose journalistic activities have crossed over into other intellectual fields.

This study applies a symbolic interactionist framework to understand how these actors managed their reputations and careers within the intellectual world. The narratives were taken from qualitative semi-structured interviews, and supported by additional research such as interviews, biographies, and articles which have been published about their lives.

The life stories were compared to the extensive structural changes affecting the world of journalism and the world of intellectuals in Brazil. This comparison revealed gaps between these two spheres of practice, within which the ambivalent form of journalists’ identities have been constructed.

This chapter offers two contributions to the study of Brazilian journalists. From a theoretical and methodological viewpoint, it advances beyond other studies that focus more on the prevailing representations of journalists’ professional identities and their role in society. From an empirical standpoint, it describes the complex negotiations between the worlds of journalism, culture and politics. This chapter also reexamines the current dominant explanation for the changes in Brazilian journalism. It shows that building careers and new levels of interpersonal cooperation for intellectuals and journalists has been a slow process. Ultimately, this development has left some behind, especially those actors stretched between multiple professional identities such as those who self-identify as intellectual-journalists.

The purpose of this study is to investigate how cross-functional integration supports the execution of the demand-side processes and its effects on both the demand and supply-side processes.

A case study was conducted including a Brazilian multinational manufacturer in the automobile industry and some of its suppliers and dealers. 17 interviews were conducted. A theoretical framework is proposed containing five basic elements, they are: characteristics of the demand/supply processes; involved functions; integration factors; context influencers and impacts of integration on demand and supply processes.

The findings present three demand-side processes (Product Launch, Marketing and Sales and Demand Planning) that demonstrated a greater need for cross-functional integration in the studied case, mainly through informal integration factors.

The empirical results of this study have methodological limitations due to the use of the case study method. Future research should analyze the effects of other context influencers (e.g. natural catastrophes, civil wars and low level of unemployment) on cross-functional integration.

The results highlight that joint planning, willingness to work together, team spirit, adequate communication and cross-functional meetings helped the studied organizations to achieve competitive advantages and improve their performance.

This study provides a theoretical framework that helped to improve the understanding of the interrelationships between demand management constructs and cross-functional integration factors. There are indications that a political–economic crisis has stimulated the existence of a willingness to work together and group spirit among employees who remain in the organization after mass dismissals. This climate of cooperation helped to increase the agility and resilience of the studied supply chain, which is currently affected by a changing market.

The 3,4-methylenedioxymetamphetamine (MDMA) content in ecstasy tablets has increased enormously throughout Europe across the past decade. This study aims to determine whether this is caused by the production of “stronger” tablets (more mg MDMA per mg of tablet), or if tablets have simply been getting larger and heavier (more mg of tablet in total).

A data set of 31,716 ecstasy tablets obtained in 2012–2021 by 10 members of the Trans European Drug Information (TEDI) network was analysed.

The MDMA mass fraction in ecstasy tablets has remained virtually unchanged over the past 10 years, with increased MDMA contents being attributed almost exclusively to increased tablet weight. These trends seem to be uniform across Europe, despite varying sampling and analytical techniques being used by the TEDI participants. The study also shows that while tablet weight correlates perfectly with MDMA content on a yearly basis, wide variations in the MDMA mass fraction make such relations irrelevant for determining the MDMA content of individual tablets.

These results provide new opportunities for harm reduction, given that size is a tangible and apparently accurate characteristic to emphasise that one tablet does not simply equate to one dose. This is particularly useful for harm reduction services without the resources for in-house quantification of large numbers of ecstasy tablets, although the results of this study also show that chemical analysis remains crucial for accurate personalised harm reduction.

The findings are both new and pertinent, providing a novel insight into the market dynamics of ecstasy tablet production at a transnational level.

The objective of this study is to analyze how cross-functional integration contributes to the development of market-oriented strategies in the context of food and beverage manufacturers in Latin America.

A multi-case study was conducted in two multinational companies in Costa Rica and Brazil. Twenty-four semi-structured interviews were carried out with managers, leaders and supervisors.

The results showed four market-oriented processes: product launch, product delivery, customer complaints solution and improvement and innovation projects. Within these processes, 12 integration factors that impact market orientation were characterized. They also indicate that the concepts of market orientation and cross-functional integration should be integrated in the organizational culture to facilitate the understanding of the different needs and levels of urgency.

The studied literature does not emphasize the way integration is operationalized to allow organizations to be market oriented. According to our findings, responsive strategies depend on the integration of various internal functions to generate market intelligence. Managers must realize that when the workers are motivated and informed, they become more willing to take on a group vision and commit to organizational goals. This paper presents seven propositions on the operationalization of market orientation through cross-functional integration.

After the end of the Napoleonic War, few issues of public policy dominated discussions in England as fervently as the issue of currency and the national debt. A time of civil unrest and social radicalisation, the circulation of ideas and pamphlets was prolific. The difficulties of post-war reconstruction sparked a long debate on issues of monetary reform and repayment of the national debt. The growth of national debt increased the size of the financial market and had important consequences for a changing class dynamic in domestic political affairs. The distributional aspects of the conflict were present, as was the satirical mockery of mishandling of public affairs. In much of the subsequent scholarship the organisation of taxation and expenditure, and the financial system and the issue of currency have been analysed as separate. This chapter brings them together. In particular, it focuses on Ricardo’s monetary thought and his views on public finance and contextualises them in light of his contemporaries.

Theoretical models of collaboration assume that intra‐organizational relationships are more collaborative that inter‐organizational ones. This paper seeks to question the validity of this assumption by comparing the levels of collaboration in two cases that comprise both types of relationship.

Two case studies in the UK food industry were conducted, in each two relationships were analyzed: one inter‐ and one intra‐organizational. Data were collected through a questionnaire followed by semi‐structured interviews.

This exploratory research indicates that in both case studies intra‐organizational relationships have lower levels of collaboration than inter‐organizational ones. This appears to contradict the commonly held assumption that intra‐organizational relationships involve closer collaborations than inter‐organizational ones.

Case study approaches have reliability and generalisability limitations, however, the paper was given in‐depth access to four relationships (two per case), which provide a basis for further research. The use of multiple informants and two methods of data collection helped to increase reliability and efforts were made to reduce bias in responses by ensuring confidentiality and engaging with participating companies in an impartial way.

A better appreciation of collaboration in inter‐ and intra‐ organizational relationships will result in managers making better decisions about how their organization relates internally and externally. This could have implications for decisions on make‐buy, alliances, and acquisitions.

The paper shows that it is possible to have relationships with customers and suppliers that are more collaborative than those between departments within a single organization. This finding appears to challenge traditional assumptions and provides a new perspective of the management of supply chain relationships.

From the perspective of business history, this chapter presents an overview of the development of the tourism sector in South America, placing special emphasis on the Peruvian case. The chapter explores various topics related to the tourism chain, such as hotel networks, the role of the state, tour operators, micro- and small enterprises, linkages between tourism and sustainability, the formation of clusters in the sector, and interactions between different entrepreneurs in the chain. Special emphasis is placed on the Peruvian case, especially when it comes to discussing the role of micro- and small enterprises in the sector.
