Dear EWGLA Participants, We are pleased to inform you that a preliminary schedule, including key dates and times, is now available on the EWGLA 2025 website. Additionally, we would like to share important information for those who have not yet completed their registration. An online card payment option (TPV) is now available, specifically for participants who may incur extra bank fees when paying via traditional bank transfer. You can find detailed instructions on how to proceed with this payment method at: https://ewgla2025.uca.es/registration/ [ https://ewgla2025.uca.es/registration/ ]. Please note that this option is intended only for those affected by additional bank charges. If this does not apply to you, we kindly ask that you continue using the standard bank transfer method. Finally, a friendly reminder that the early registration deadline is May 15. We hope this facilitates your registration process, and we look forward to welcoming you in September.

Location related references May 2025 collection
by Frank Plastria 05 May '25

05 May '25

Dear fellow locater, Here is the May 2025 collection: 81 references about or related to location science, almost half brand new from this year, the other almost half from2020, as well as a few missing items from my previous collections for the years in between. There are still many hundreds to come before filling the gap I left since my retirement in 2013, so this monthly column started up again in July 2023 will be continued for quite a while (I hope). Working backwards at this pace the backlog might take another two or three years at least. And new ones keep flowing in at an incredible rate ... Cheers Frank Prof. Em.

Frank's location references on SciWheel
by Joerg Kalcsics 17 Mar '25

17 Mar '25

Dear all, after Frank Plastria thankfully restarted his monthly column on location related references, he contacted Bogi and myself to see if we can make all the references he collected so far, as well as future ones, available to the community in a single place. After a bit of searching and trialling, Bogi and myself settled on the online platform SciWheel, which is free to use. We have uploaded all references Frank collected up to 2013 to SciWheel (over 2600). We have also added the ones from his monthly column up to now and will continue to do so in the future. Moreover, Frank was given access and permission to use Hale's bibliography and is currently reviewing it to fill in missing parts. Once this is done, we will also be able to upload those. If you find that some of your own references are missing or incorrect, then you are very welcome to upload them yourself or fix them, respectively. Apart from being free-to-use, another important feature for us was that SciWheel allows to add tags to references. While there is obviously a search function, it is not always easy to narrow down the search to specific "types" of topics. For example, myself being a (die-hard) fan of network location, finding all papers on those problems is not always easy. We have already created a handful of tags and every user can define new tags. While it will be difficult (or even impossible) to retrospectively assign such tags, we very much hope that we, as a community, can get this going for future references. Creating and adding tags is straight-forward, so please feel free to do so. The only thing we would ask is that you try not to define tags that are too specific, so that we do not to end up with too many of them. That would defy their purpose and also you cannot search over tags. Finally, to get access to the database, we need to send you an invitation from within SciWheel to an email address of your choice (unfortunately, there is no self-enrolment option). If you want to be added, then please fill the form: https://forms.gle/5tGTU7ajbeHH7Pib7 Last, but most certainly not least, a very big thank you to Frank for restarting his column and allowing us to upload the references to SciWheel!

EWGLA video for EURO 50th anniversary
by SERENA FUGARO 07 Mar '25

07 Mar '25

Dear EWGLA Members, We have been invited to record a video clip to help disseminate the activities of the Working Group as part of the 50th anniversary celebrations of EURO. The 3-5 minute video will be recorded on Zoom on 12 March between 12pm and 1 pm (CET) and it will be edited later by an editor for EURO, to be shown during the conference and thus being open to the broad community of EURO. We would like to ask if any of you would be happy to participate in the video by briefly answering one of the following questions: * How would you define EWGLA or what does it mean to you? * What are the first things that come to your mind when you think of EWGLA? * How would you define EWGLA meetings? * What are your most unforgettable/prominent memories of EWGLA meetings? * How would you complete the following sentence: 'Thanks to EWGLA, .....'? * For the first members of EWGLA, would you tell us the story of how EWGLA was born in 1984 and/or something about the first EWGLA meeting in 1985? Could you please let us know by Tuesday 11 March at 1pm (CET) if you would be interested by filling in the form at this link https://forms.office.com/e/HmXC4VbYKr? You will receive an invitation with the Zoom link and all the instructions in due course. Thank you for your support, we look forward to meeting many of you in Leeds! Diego, Hatice and Serena

EWGLA Coordination Board advocates Diversity, Equality and Inclusion
by Hatice ÇALIK 03 Mar '25

03 Mar '25

Dear colleagues and friends, We are reaching out to you regarding some updates about the EWGLA website and social media accounts. For better dissemination and visibility of EWGLA activities as well as the ‘Location-related’ activities of the EWGLA members, we are currently in the process of setting up a public LinkedIn page and a BlueSky account for EWGLA. We will inform you when these new profiles are available and look forward to better disseminating our research to the world. As board members, we are committed to diversity, equality and inclusion. In this regard, we will be taking two actions. 1. At the invitation of the EURO WISDOM Forum<https://www.euro-online.org/web/pages/1654/wisdom>, we will include the following statement on the EWGLA website as well as in our calls for participation in EWGLA events: "We endorse the EURO WISDOM Forum<https://www.euro-online.org/web/pages/1654/wisdom> objectives to support, empower and encourage the participation of all genders in OR." 2. We will close the EWGLA Twitter account. As part of EWGLA's democratic tradition, we are open to receiving objections to any of our decisions. If this is the case, please email us at ewgla-board(a)mail.euro-online.org<mailto:ewgla-board@mail.euro-online.org>. EWGLA Coordination Board

Dear Locators, We are delighted to announce that EWGLA is once again offering grants to support the participation of six young researchers (doctoral defense not earlier than March 2023) and researchers from economically weak countries for attending the next EWGLA meeting, which will be held in Jerez (Spain) from 17 to 19 September 2025 https://ewgla2025.uca.es/. The grants will cover the expenses for early registration and travel for up to a total of 500 EUR for each grantee. To apply, you have to be a member of EWGLA, and you should send the following documents as a single PDF by e-mail to the EWGLA Board (ewgla-board(a)mail.euro-online.org) * The abstract submitted to the conference, * Your CV, * A letter of recommendation from your supervisor (if you are a PhD student). Deadline for applications: 15 Mar 2025 Notification about grants: 26 Mar 2025 The grant recipients will be asked to prepare a 2-page report and a short video summarizing the experience at the conference. Below, you can watch the video made by grantees attending the last EWGLA meeting: https://drive.google.com/file/d/1It1KKzu9_gSC69mJu9i0Ucmz0PpLTO59/view?usp=… Please forward this announcement to any potential interested and, of course, encourage them to become members!
