The semantic differential is a widely applied measurement technique in the information systems field. As wedemonstrate in this study, however, there is evidence that many of the applications of the semantic differentialseem to be subject to common shortcomings. In this study, we address these shortcomings by creatingawareness of the requirements underlying semantic differentiation. We discuss the requirements of semanticdifferentiation and use them as a foundation to introduce a framework to assist researchers in applying thesemantic differential more adequately. The framework puts renewed emphasis on bipolar scale selection anddimensionality testing, introduces semantic bipolarity as new criterion, and proposes distinct stages for thetesting of wording and contextual contamination. We exemplify the framework using an illustration exercise,which centers on the assessment of the meaning of the concept “electronic marketplace quality”. Using amixture of qualitative and quantitative methods, the illustration exercise clarifies the prerequisites for semantic differentiation and provides suggestions for researchers. The paper concludes with a discussion of several methodological implications.

Crime scene investigations are highly complex environments that require the CSI to engage in complex decision-making. CSIs must rely on personal experience, context information, and scientific knowledge about the fundamental principles of forensic science to both find and correctly interpret ambiguous traces and accurately reconstruct a scene. Differences in CSI decision making can arise in multiple stages of a crime scene investigation. Given its crucial role in forensic investigation, CSI decision-making must be further studied to understand how differences may arise during the stages of a crime scene investigation. The following exploratory research project is a first step at comparing how crime scene investigations of violent robberies are conducted between 25 crime scene investigators from nine countries across the world.Through a mock crime scene and semi-structured interview, we observed that CSIs have adopted a variety of investigation approaches. The results show that CSIs have different working strategies and make different decisions when it comes to the construction of relevant hypotheses, their search strategy, and the collection of traces. These different decisions may, amongst other factors, be due to the use of prior information, a CSI’s knowledge and experience, and the perceived goal of their investigation. We suggest the development of more practical guidelines to aid CSIs through a hypothetico-deductive reasoning process, where (a) CSIs are supported in the correct use of contextual information, (b) outside knowledge and expertise are integrated into this process, and (c) CSIs are guided in the evaluation of the utility of their traces.

Epistemological relativism in tourism studies has been conceivably paralyzed by the concept of a, or, the "paradigm." In this review article, Platenkamp metaphorically identifies these paradigms with the islands that Odysseus visited (all those centuries ago) during his well-recorded journey to Ithaca. In this context, therefore, Ithaca is changed (by Platenkamp) from being just an idyllic Greek homeland into a contemporary, hybridized world like-in our time-of the multilayered network society in Africa of the capital of Ghana, Kumasi. The basic question for Platenkamp, then, is that of how tourism studies researchers can (or ought?) leave their safe islands (i.e., their paradigms) and organize their own paradigm dialog (after Guba) with others around them on their uncertain and risky voyage to Kumasi. In an attempt to clarify this vital kind of dialog, Platenkamp introduces Said's principles of reception and resistance, but also focuses on the distinction between different modes of "knowledge production" that have been introduced into the social sciences since the 1990s. In this light, to Platenkamp, the uncertainty of this ongoing/unending epistemological quest remains crucial: to him, all (almost all?) believers in a, or any, paradigm within tourism studies are unhealthily "overimmunized" by the tall claims and the perhaps undersuspected strategies of the particular "paradigm" they follow.

The study of human factors in forensic science informs our understanding of the interaction between humans and the systems they use. The Expert Working Group (EWG) on Human Factors in Forensic DNA Interpretation used a systems approach to conduct a scientific assessment of the effects of human factors on forensic DNA interpretation with the goal of recommending approaches to improve practice and reduce the likelihood and consequence of errors. This effort resulted in 44 recommendations. The EWG designed many of these recommendations to improve the production, interpretation, evaluation, documentation, and communication of DNA comparison results.

This systematic review describes and discusses three commercially available integrated systems for forensic DNA analysis, i.e., ParaDNA, RapidHIT, and ANDE. A variety of aspects, such as performance, time-to-result, ease-of-use, portability, and costs (per analysis run) of these three (modified) rapid DNA analysis systems, are considered. Despite their advantages and developmental progress, major steps still have to be made before rapid systems can be broadly applied at crime scenes for full DNA profiling. Aspects in particular that need (further) improvement are portability, performance, the possibility to analyze a (wider) variety of (complex) forensic samples, and (cartridge) costs. Moreover, steps forward regarding ease-of-use and time-to-result will benefit the broader use of commercial rapid DNA systems. In fact, it would be a profit if rapid DNA systems could be used for full DNA profile generation as well as indicative analyses that can give direction to forensic investigators which will speed up investigations.

This thesis focuses on the effectiveness of a family-centered approach (in Dutch “DMOprotocol”, further referred to as the family-centered approach), designed for monitoring and enhancing children’s social-emotional development in Preventive Child Healthcare (PCH). The effectiveness study took place at a Dutch PCH organization (Icare JGZ). In a quasi-experimental design, regions in which the family-centered approach had already been implemented (northern and southeastern part of Drenthe) were compared to regions in which care-as-usual had been maintained (northern part of Overijssel). The aim was to assess the added value of the family-centered approach from different perspectives. Therefore several research questions were answered in analyses that arereported in different chapters of this thesis.

This paper analyses the initiative AgroAgenda in the northern Netherlands. The AgroAgenda is a platform in which multiple stakeholders together stimulate a circular, and nature-inclusive agro-food system in the Dutch provinces of Friesland, Groningen and Drenthe. Stakeholders come from, among others, provincial governments, farmers’ and nature organizations, educational and research institutes and processing companies. They join forces to realize a system change, a transition, in the region, while promoting knowledge circulation, knowledge co-creation and joint learning. The platform, is a front runner of five national, comparable initiatives. The AgroAgenda has the potential to lead to a more nature-inclusive and circular farming. Several of the 40 experiments have already led to good results. However, to bring about a real system change, more attention to innovations in governmental organizations (including law and regulations), policy, the value chains (division of margins, pricing and marketing) and the educational system are needed.

Technological innovations enable rapid DNA analysis implementation possibilities. Concordantly, rapid DNA devices are being used in practice. However, the effects of implementing rapid DNA technologies in the crime scene investigation procedure have only been evaluated to a limited extent. In this study a field experiment was set up comparing 47 real crime scene cases following a rapid DNA analysis procedure outside of the laboratory (decentral), with 50 cases following the regular DNA analysis procedure at the forensic laboratory. The impact on duration of the investigative process, and on the quality of the analyzed trace results (97 blood and 38 saliva traces) was measured. The results of the study show that the duration of the investigation process has been significantly reduced in cases where the decentral rapid DNA procedure was deployed, compared to cases where the regular procedure was used. Most of the delay in the regular process lies in the procedural steps during the police investigation, not in the DNA analysis, which highlights the importance of an effective work process and having sufficient capacity available. This study also shows that rapid DNA techniques are less sensitive than regular DNA analysis equipment. The device used in this study was only to a limited extent suitable for the analysis of saliva traces secured at the crime scene and can mainly be used for the analysis of visible blood traces with an expected high DNA quantity of a single donor.
