Onderzoek naar de effectiviteit van het side-event programma bij het wereldkampioenschoep CP Voetbal in Drenthe in 2011. Onderzocht is in welke mate de verschillende side-events een bijdrage leverden aan de doelstellingen van het hoofdevenement. Het onderzoek vond plaats binnen het kader van de pilot van het Ministerie van Volksgezondheid, Welzijn en Sport (VWS) om kennis te ontwikkelen over sportevenementen

Using the lost letter technique to measure real-life behavioral effects of alcohol use

Introduction and aims: People’s behaviors after alcohol use are more extreme and alcohol has a narrowing effect on a person’s cognitive capacity. We tested this effect, making use of the Lost-Letter Technique (LLT), in which the return rate of “lost letters” by public mail is used to measure altruistic behavior. We hypothesized that return rates would be lower when people are under the influence of alcohol, and that an anti-alcohol prime in the address would even further decrease return rates. Design and methods: 768 letters were dropped, half of those at times when some degree of intoxication was likely versus when sober passers-by were common. Three different addressees were used to convey an anti-alcohol cue, a charitable cue, and a neutral cue. Results: The average response rate was 33.1%, and was significantly lower during late bar hours than during lunch hours (20.3% versus 45.8%). Also, when envelopes were found by people who were more likely to have consumed alcohol, anti-alcohol cues gained significantly lower response rates (12.7% versus 23.1%). Discussion and conclusions: This study confirms that alcohol use causes less altruistic behavior and different responses to alcohol-related cues, suggesting that LLT is a promising method to study people’s behavior. Future research could also focus on other substances, (mood-)states, and technology as a means of data collection

Methodological Challenges in Studying Trust in Natural Resources Management

Trust has been identified as a central characteristic of successful natural resource management (NRM), particularly in the context of implementing participatory approaches to stakeholder engagement. Trust is, however, a multi-dimensional and multi-level concept that is known to evolve recursively through time, challenging efforts to empirically measure its impact on collaboration in different NRM settings. In this communication we identify some of the challenges associated with conceptualizing and operationalizing trust in NRM field research, and pay particular attention to the inter-relationships between the concepts of trust, perceived risk and control due to their multidimensional and interacting roles in inter-organizational collaboration. The challenge of studying trust begins with its conceptualization, which impacts the terminology being used, thereby affecting the subsequent operationalization of trust in survey and interview measures, and the interpretation of these measures by engaged stakeholders. Building from this understanding, we highlight some of the key methodological considerations, including how trust is being conceptualized and how the associated measures are being developed, deployed, and validated in order to facilitate cross-context and cross-level comparisons. Until these key methodological issues are overcome, the nuanced roles of trust in NRM will remain unclear

Preview Brief 2: Wildland Fire Management under COVID-19, Survey Results

Wildland fire management is impacted by COVID-19 as a result of strict hygiene and social distancing requirements. Here, we give a preview of the of our online survey (link) that aimed to clarify implications of COVID-19 restrictions on wildland fire management, map current thinking, and collate any plans, protocols or procedures to generate generic guidance for wildland fire professionals. The survey was completed by 443 individuals from over 38 countries, working at a large variety of organizations in terms of organization type, level of jurisdiction, primary function, and the size of the fire management and fire suppression work force. This preview includes the most important preliminary results. In short, the data indicates that people are worried about the effect of COVID-19 on wildland fire management and also expect this to impede management. Despite this, there is high confidence that operations can be continued during the pandemic. COVID-19 hygiene and distancing requirements are being widely adopted, which is being reflected by a reduced number of staff per vehicle. There is an expected reduction in support services being available. Notable to mention is furthermore the expected reduction in sharing and receiving of resources (from and to other countries, regions) in times of need. Finally, training and risk reduction activities are also impacted, suggesting a longer-term impact of the pandemic on fire management. Two main concerns highlighted by survey respondents are the lack of preventive COVID-19 testing amongst wildland fire fighters, and the increased risk of vehicle accidents if staff is spread across more vehicles. We are now analyzing the wealth of responses including over 30.000 words of comments shared, and plan to publish the full analysis mid Jun

Managing inter-organizational trust and risk perceptions in transboundary fisheries governance networks

Transboundary fishery management represents a significant governance challenge that requires ongoing inter-organizational communication, collaboration, and collective action to ensure sustainability. Previous research suggests that different dimensions of perceived risk, trust, and control interact in complex ways to affect inter-organizational collaborative performance, providing an administrative ‘architecture’ that enables partners to share resources, engage in teamwork, resolve conflict, and coordinate tasks and responsibilities while also allaying their concerns about the alliance. However, the extent to which different control mechanisms influence trust and mitigate the perceived risks of collaboration between the diverse organizations involved in transboundary fisheries management remains unclear. This paper presents the quantitative results of survey research conducted in the Salish Sea of North America, an ecosystem spanning the Canada-US border between British Columbia and Washington State. The survey instrument operationalizes a multi-dimensional trust-control-risk framework considered suitable for studying inter-organizational natural resource management (NRM) networks. The findings support descriptions of the Salish Sea as having fewer nation-to-nation governing bodies resulting in a lack of effective formal controls, high perceived regulatory risk, and low procedural trust attributes that can negatively affect the collaborative performance of the fishery management network. This study represents the first quantitative analysis of the complex relationships between different inter-organizational management strategies, trust dimensions, and perceived risks in transboundary fisheries governance, and offers new directions for future research on NRM collaboration

Spin-orbit interaction in a dual gated InAs/GaSb quantum well

Spin-orbit interaction is investigated in a dual gated InAs/GaSb quantum well. Using an electric field the quantum well can be tuned between a single carrier regime with exclusively electrons as carriers and a two-carriers regime where electrons and holes coexist. Spin-orbit interaction in both regimes manifests itself as a beating in the Shubnikov-de Haas oscillations. In the single carrier regime the linear Dresselhaus strength is characterized by $\beta =$ 28.5 meV$\AA$ and the Rashba coefficient $\alpha$ is tuned from 75 to 53 meV$\AA$ by changing the electric field. In the two-carriers regime the spin splitting shows a nonmonotonic behavior with gate voltage, which is consistent with our band structure calculations
