ABSTRACT Purpose of this paper This paper aims to study different aspects of a logistics purchasing process from both the buyer's and supplier's perspective to compare literature and practice. Design/methodology/approach A multiple case study approach is chosen based on the exploratory character of the study. Seven recent logistics purchasing projects are studied by means of semi-structured interviews and company documents. Findings Literature review makes clear that the complexity of outsourced logistics services increased. As a result, buyers of these services should adapt their purchasing process to thoroughly think through its purchasing processes before going on the market, and to fully benefit from the expertise of service providers. Nevertheless, the cases show that most buyers still follow a traditional purchasing approach and process where service providers are not involved in defining the specifications of the logistics services. As a result shippers do not fully benefit from the expertise and possibilities of the service providers. Research limitations/implications The research is qualitative in nature and therefore limited to making theoretical propositions and to generalizing the findings to the total population. This must be accomplished through additional empirical verification. Practical implications The paper shows that both shippers and logistics service providers could improve their competitive position by changing the purchasing process and approach for logistics services. What is original/value of paper Our research differs from existing publications on logistics outsourcing for two reasons: 1) Existing publications do not primarily focus on the aspect of supplier involvement in purchasing logistics services. 2) Our study involves both the buyer's and the supplier's perspective.

Doelstellingen De mate van betrokkenheid van jonge gebruikers bij wervingsadvertenties voor geldezels op Instagram onderzoeken. Methoden Drie advertenties die de belangrijkste mechanismen voor betrokkenheid bij cybercriminaliteit weerspiegelen en gericht waren op Nederlandse gebruikersclusters werden op twee Instagram-plaatsingen geplaatst. Door middel van dit quasi-experimentele 3 × 2 factorial design konden we het bereik en de weergaven van de advertenties, de doorklikratio's, het geslacht van de deelnemers en de temporele verdelingen van de gebruikersbetrokkenheid analyseren. Resultaten De analyse toont aan dat tot 3% van de jonge gebruikers zich bezighield met de advertenties, vooral met advertenties die een luxe levensstijl promoten en neutralisatietechnieken gebruiken. Mannen waren vaker betrokken en 's nachts werd er meer geklikt. Conclusies Sommige jonge Instagram-gebruikers lijken geneigd om geld te verdienen via hun bankpas en lopen het risico om online betrokken te raken bij cybercriminaliteit. We moedigen toekomstig onderzoek aan om het gebruik van sociale media in criminologische studies verder te onderzoeken. ENGLISH Objectives Examine the level of engagement of young users with money mule recruitment ads on Instagram. Methods Three ads reflecting key cybercrime involvement mechanisms and targeting Dutch user clusters were run on two Instagram placements. By means of this quasi-experimental 3 × 2 factorial design, we were able to analyze the reach and views of the ads, click-through rates, gender of the participants, and temporal distributions of user engagement. Results Mimicking actual recruitment environments, analysis shows that up to 3% of young users engaged with the ads, especially those promoting a luxury lifestyle and using neutralization techniques. Men were more likely to engage, and click-through rates were higher at night. Conclusions Some young Instagram users seem prone to making money through their bank cards and risk becoming involved in cybercrime online. We encourage future research to explore further the use of social media in criminological studies.

The the agriculture sector in developing countries has a large production share in the global fresh fruit market. Yet, in many cases, the land production yield indices at the orchard level are lower than the values related to more technologically developed countries. This situation leads to economic losses due to poor performance in productivity, efficiency and quality, which in turn is related to a technological and managerial gap. In this chapter, an operations management framework is proposed that tries to balance the market requirements (i.e. quality and quantity) with the capacity of the production system. This is performed through a multi-objective optimization approach that helps orchard managers synchronize the production yields with market demand and quality requirements. The model also allows the production managers to have a forecasting tool based on historical data. The model integrates the full supply chain through a set of sub-models for each stage of the production life cycle. The objective of the model is to minimize cost while maximizing sales. The optimization strategy involves a variant of the so-called NSGA II algorithm. The case study of an exporting lime packaging company is developed to illustrate the proposed framework and its possible impact on performance.

In Amsterdam's neighbourhoods, much of the waste that is disposed has the potential of becoming something else by means of recycling or upcycling. Zero Waste lab –which is part of the organization De Gezonde Stad- is a place where inhabitants can bring their own separated waste in exchange for value coins. Now, Zero Waste Lab now wants to take this a step forward and further develop their own project: from recycling to upcycling waste. In this endeavour, HvA will collaborate by researching the possibilities for upcycling a local waste stream by means of digital production pro-cesses, as well as ways of involving the neighbourhood. Because it is of vital importance for the project not only to be technically possible, but also scalable and economically feasible, Zero Waste Lab and HvA have asked for partnership to the company Verdraaid Goed. This partnership and specific case study, presented here as ‘Wood for the neighborhood’ can be summa-rized in four main goals: • (Production) Explore the design and manufacturing possibilities of using digital production to upcycle a local wood waste stream (with an industrial robotic arm) • (Design) Show how explorative research, when carried on from the beginning of the de-sign process, can bring great added value to the development of project concepts. • (Social) Demonstrate that involving stakeholders early in the process of reusing and de-signing with waste materials can shape the future in new directions • (All three) Highlight how this case study is relevant and fits the principles of the circular economy.
