+
+# Editing this README
+
+When you're ready to make this README your own, just edit this file and use the handy template below (or feel free to structure it however you want - this is just a starting point!). Thanks to [makeareadme.com](https://www.makeareadme.com/) for this template.
+
+## Suggestions for a good README
+
+Every project is different, so consider which of these sections apply to yours. The sections used in the template are suggestions for most open source projects. Also keep in mind that while a README can be too long and detailed, too long is better than too short. If you think your README is too long, consider utilizing another form of documentation rather than cutting out information.
+
+## Name
+Choose a self-explaining name for your project.
+
+## Description
+Let people know what your project can do specifically. Provide context and add a link to any reference visitors might be unfamiliar with. A list of Features or a Background subsection can also be added here. If there are alternatives to your project, this is a good place to list differentiating factors.
+
+## Badges
+On some READMEs, you may see small images that convey metadata, such as whether or not all the tests are passing for the project. You can use Shields to add some to your README. Many services also have instructions for adding a badge.
+
+## Visuals
+Depending on what you are making, it can be a good idea to include screenshots or even a video (you'll frequently see GIFs rather than actual videos). Tools like ttygif can help, but check out Asciinema for a more sophisticated method.
+
+## Installation
+Within a particular ecosystem, there may be a common way of installing things, such as using Yarn, NuGet, or Homebrew. However, consider the possibility that whoever is reading your README is a novice and would like more guidance. Listing specific steps helps remove ambiguity and gets people to using your project as quickly as possible. If it only runs in a specific context like a particular programming language version or operating system or has dependencies that have to be installed manually, also add a Requirements subsection.
+
+## Usage
+Use examples liberally, and show the expected output if you can. It's helpful to have inline the smallest example of usage that you can demonstrate, while providing links to more sophisticated examples if they are too long to reasonably include in the README.
+
+## Support
+Tell people where they can go to for help. It can be any combination of an issue tracker, a chat room, an email address, etc.
+
+## Roadmap
+If you have ideas for releases in the future, it is a good idea to list them in the README.
+
+## Contributing
+State if you are open to contributions and what your requirements are for accepting them.
+
+For people who want to make changes to your project, it's helpful to have some documentation on how to get started. Perhaps there is a script that they should run or some environment variables that they need to set. Make these steps explicit. These instructions could also be useful to your future self.
+
+You can also document commands to lint the code or run tests. These steps help to ensure high code quality and reduce the likelihood that the changes inadvertently break something. Having instructions for running tests is especially helpful if it requires external setup, such as starting a Selenium server for testing in a browser.
+
+## Authors and acknowledgment
+Show your appreciation to those who have contributed to the project.
+
+## License
+For open source projects, say how it is licensed.
+
+## Project status
+If you have run out of energy or time for your project, put a note at the top of the README saying that development has slowed down or stopped completely. Someone may choose to fork your project or volunteer to step in as a maintainer or owner, allowing your project to keep going. You can also make an explicit request for maintainers.

+# Motivation & Research Contribution
+
+## Motivation (1)
+
+::: incremental
+-   **Stated preference** methods are frequently applied in **environmental valuation** to estimate economic values of policies, goods, and services that cannot be valued otherwise
+-   Stated preference methods face **validity challenges**
+-   Valid value estimation requires **sufficient information** provision about the good being valued
+-   Still unclear **what formats of information provision** and **how much information** are optimal for valid preference elicitation
+:::
+
+## Motivation (2)
+
+::: incremental
+-   Too **much information** may increase survey **complexity**, leading to respondents being overburdened with it and producing less consistent choices
+-   Too **little information** may lead respondents to **not** being able to make an **informed choice**
+-   Valid preference elicitation depends not only on the provision of information, but also on the **appropriate processing and recall** of the information by the respondent
+-   **Optional information** allows the respondents to gather required information if needed and might increase efficiency of information provision
+
+-  Providing optional information should enhance optimal information seeking leading to less heterogeneity in good-specific knowledge between the respondents 
+:::
+
+## Literature
+
+::: incremental
+-   There is **little research** on the effects of **optional information provision** on choice behavior and information recall
+-   In their study, @tienhaara2022information surveyed preferences for agricultural genetic resources, allowing respondents the option to access detailed information on the valued goods prior to preference elicitation
+-   Similarly, @hu2009consumers offered respondents the opportunity to access optional information about genetic modified food before participating in a choice experiment
+-   Both studies conclude that, on average, respondents who voluntary retrieve information have **larger willingness to pay** for the good to be valued
+-   Their study design, however, does not allow comparing the optional information retrieval to a version where the additional information was shown obligatory
+:::
+
+## Research Contribution
+
+::: incremental
+-   Our study explores the impact of additional obligatory and optional information on stated preferences using an exogenous split sample approach with three treatments
+-   We investigate the effects of information treatments on survey engagement, information recall, consequentiality, and stated preferences, similar to @welling2023information, expanding our understanding of treatment effects
+-   We test who chooses additional information and to what extent their preferences differ from those who do not choose additional information
+:::
+
+## Research Questions
+
+::: incremental
+1.  Do obligatory and optional information provision affect **survey engagement**, **information recall**, **consequentiality**, and **stated preferences**?
+
+- OLS and MXL with interactions
+
+2.  Do **socio-demographic** or **attitudinal** variables influence the decision to **access optional information**?
+
+- Logit regression
+
+3.  Do **survey engagement**, **information recall**, **consequentiality**, and **stated preferences** differ between respondents who **voluntary access information** and those who do not?

+# Survey & Data
+
+## Discrete Choice Experiment
+
+::: incremental
+-   To investigate the research questions, we use data from a **discrete choice experiment (DCE)** on naturalness of urban green spaces in the 14 largest German cities
+-   The survey is an exact **replication** of the choice experiment of @Bronnmann062321-0072R1 and differs only in the information provided to the respondents
+-   In the DCE, respondents were asked to imagine possible **changes** to their **most frequently used UGS**
+-   This **restructuring** involved adjustments to the UGS's **naturalness** and changes to the **walking distance**
+-   The associated **costs** of this restructuring were intended to be integrated into monthly **rental payments**
+<!-- -   Participants in the DCE were presented **ten** randomly assigned **choice cards** with a choice between **two alternative programs** for the renovation of the UGS and the **current status quo**. -->
+:::
+
+## Choice Card
+
+![](images/Figure%202.PNG){width="300"}
+
+## Treatment (Information Provision)
+
+-   Info text about the effect of **natural urban green spaces** on urban **heat islands**
+-   **Optional video** (2 minutes) with the almost the same information
+
+![](images/waermeinsel.png){width="200"}
+
+## Treatment (Quiz & Self Reference Questions)
+
+::: incremental
+-   **Seven quiz questions** with strict reference to the previously provided information
+
+-   Example: *The temperature difference between the city and the surrounding area can be up to 10 degrees Celsius. (true/false)*
+
+-   **Two self reference questions**
+
+-   Example: *The city should do more to avoid heat islands. (Strongly agree - Strongly disagree)*
+:::
+
+
+
+
+
+
+
+## Additional Data
+
+::: incremental
+
++   Quiz: Evaluation of the quiz we gave to everyone after the DCE.**-\>Information recall**
+
++   Timings: We saved the net interview time and the mean Choice Card time.-\> **Survey engagement**
+
++   Two questions on **consequentiality **
+
+- Example: *To what extent do you believe that the decisions you make will have an impact on how the green spaces in your neighborhood are designed in the future? (I believe in it very much - I don’t believe in it at all)*
+
++   **Socio-demographics**: Age, Gender, Income, Education
+
++   **Attitudinal variable**: Measure derived from 21 items on **nature relatedness** [@nisbet2009nature]

+# Discussion
+
+## Discussion (1)
+
+1.  Do obligatory and optional information provision affect survey engagement, information recall, consequentiality, and stated preferences?
+
+::: incremental
+-   Obligatory and optional treatments do not increase survey engagement measured via time spend on the survey
+
+-   Both treatments increase information recall, stronger effect for obligatory treatment
+
+-   No effects on consequentiality
+
+-   Strong effects on stated preferences for both treatments, more pronounced effect for the obligatory treatment
+:::
+
+## Discussion (2)
+
+2.  Do socio-demographic or attitudinal variables influence the decision to access optional information?
+
+::: incremental
+-   Respondents that voluntary access information are younger, richer and have a higher natural relatedness index
+
+-   No effects of gender and education
+
+-   Respondents' preferences for the good to be valued (NR-index) influence the likelihood of accessing additional information
+:::
+
+## Discussion (3)
+
+3.  Do survey engagement, information recall, consequentiality, and stated preferences differ between respondents who voluntary access information and those who do not?
+
+::: incremental
+-   Respondents that voluntary access information do not engage more in the survey, but perform best in the quiz
+
+-   Respondents that decide to not access additional information engage less in the survey, have a lower consequentiality score and do not perform different in the quiz than the non-treated respondents
+
+-   Highest willingness to pay values in the group that voluntary accesses information
+:::
+
+## Conclusion
+
+::: incremental
+-   Providing optional information does not lead to optional information seeking
+
+-   Optional information is mostly accessed by people that are interested in the good to be valued
+
+-   We recommend to use obligatory information provision rather than optional one

However, little is known about the value of nature in UGS. We developed a graphical measurement scale for the naturalness of UGS, with 5 steps between largely sealed and largely wilderness, which was embedded in an online survey and a discrete choice experiment. Using mixed logit models, we find that German citizens have a mean willingness to pay of {\texteuro}20.25 per month for an increase in the naturalness of the closest UGS by one step.},

The authors propose a new construct, Nature Relatedness (NR), and a scale that assesses the affective, cognitive, and experiential aspects of individuals' connection to nature. In Study 1, the authors explored the internal structure of the NR item responses in a sample of 831 participants using factor analysis. They tested the construct validity of NR with respect to an assortment of environmental and personality measures. In Study 2, they employed experience sampling methodology examining if NR people spend more time outdoors, in nature. Across studies, NR correlated with environmental scales, behavior, and frequency of time in nature, supporting the reliability and validity of NR, as well as the contribution of NR (over and above other measures) to environmental concern and behavior. The potential of NR as a useful method for investigating human-nature relationships and the processes underlying environmental concern and behaviors are discussed. }

Using this overview, the authors explore two of the most common conceptual misunderstandings related to framing and their implications for political communication research. This includes an overview of the different approaches to framing in political communication research, more specifically, and of the relationship between framing and related effects models, such as priming and agenda setting. The authors conclude with a recommendation that framing research be redirected away from confounded “emphasis frames” toward “equivalence frames” in the original tradition by expanding the sample of potential frames to include nonverbal visual cues.},
