Land use and conservation in the San Juan Islands

This is a community discussion on issues related to the Land Bank and how they could adapt to best address the community's interests. Your voice is needed to help them fulfill their stated mission and serve our community. Please join the effort below to inform what the community wants for this area, now and for future generations. The current mandate of the Land Bank is to "preserve in perpetuity areas in the county that have environmental, agricultural, aesthetic, cultural, scientific, historic, scenic or low-intensity recreational value and to protect existing and future sources of potable water."

This discussion will run through July, and outcomes will be communicated back to the Land Bank and community, providing insight into view distributions and with the potential of informing Land Bank policy going forward.

My name is Kaj Litch, and I am running this as part of an internship through Spring Street International School.

You may vote on as many questions as you like, any contribution is meaningful. If you return to the discussion new statements will be available for your input.

Explanations

Analysis

Popularity

"Popularity" measures how popular is a set of comments for the participants. It is equal to the total amount of positive votes (a.k.a. thumbs-up, or approvals) received by the comments in the selection.

Inclusion

"Inclusion" measures the percentage of participants included in the selection. That is, the percentage of participants who expressed a positive opinion (a.k.a. thumb-up, or approval) about at least one of the selected comments.

For instance, an inclusion of 60% means that 60% of the participants feel positively about at least one comment of the selection.

Inclusion can also be expressed in terms of satisfaction: the inclusion is the percentage of participants with non-zero satisfaction.

Satisfaction

The "satisfaction of a participant" measures the number of selected comments that they expressed a positive opinion (a.k.a. thumb-up, or approval) about.

For instance, a satisfaction of 3 means that the participant feels positively about 3 of the selected comments.

Selection Methods

A selection method is a procedure that selects a given number of comments based on the votes submitted by the users.

The desired number of comments to select is always given up-front.

Approval Voting: Selects the comments who have the highest number of votes.

Chamberlin–Courant: A participant is considered to be represented if their satisfaction is more than 0. This method selects comments to maximize the number of represented participants.

Method of Equal Shares: Each participant receives an equal amount of virtual currency to spend on comments they feel positively about. Comments are considered in rounds. A comment is selected if its supporters have enough budget left to collectively afford it.

Method of Equal Shares with Approval Voting Completion: Applies the method of equal shares. If fewer than the desired number of comments are selected, the result is completed by using the approval voting selection method.

Method of Equal Shares with Increment Completion: Calculates the minimum amount of virtual currency needed for the method of equal shares to select the desired number of comments. Then, applies the method using that amount.

Proportional Approval Voting: Selects a proportionally representative set of comments by using decreasing weight for the participants. The weight of a participant decreases with the number of supported comment that has been selected. In other words, the higher the satisfaction of a participant, the less the selection method tries to increase their satisfaction.

Sequential Proportional Approval Voting: Sequential variant the proportional approval voting method. Selects the comments one by one, each time selecting the best non-selected comment according to the principles of proportional approval voting.

Eneström–Phragmén: Distributes representation load evenly among participants to select a proportionally representative set of comments.

Phragmén's Sequential Rule: Sequentially adds comments while balancing the representation load to maintain proportional fairness.

Satisfaction Approval Voting: Selects a set of comments that maximises the total average satisfaction of the participants. The average satisfaction of a participant is defined here as their satisfaction divided by number of supported comments.
