      <Desc>THE INTERNATIONAL SOCIETY FOR HUMAN ETHOLOGY (ISHE) PROMOTES ETHOLOGICAL PERSPECTIVES IN THE SCIENTIFIC STUDY OF HUMANS WORLDWIDE. ISHE AIMS TO ACHIEVE THIS GOAL THROUGH:1. ENCOURAGING EMPIRICAL RESEARCH IN THE FIELD OF HUMAN BEHAVIOR, USING THE FULL RANGE OF METHODS DEVELOPED IN BIOLOGY AND THE HUMAN BEHAVIORAL SCIENCES AND OPERATING WITHIN THE CONCEPTUAL FRAMEWORK PROVIDED BY EVOLUTIONARY THEORY.2. PROMOTING THE EXCHANGE OF ETHOLOGICAL KNOWLEDGE AND OPINIONS WITH THE OTHER EMPIRICAL SCIENCES OF HUMAN BEHAVIOR.WE ADMINISTER OUR FUNDS IN ORDER TO PURSUE THESE GOALS.IN 2022, Three "OWEN F ALDIS" SCHOLARSHIPS WERE AWARDED TO GRADUATE STUDENTS STUDYING IN THE FIELD OF HUMAN ETHOLOGY TO ENABLE THEM TO ENGAGE IN RESEARCH ACTIVITIES THEY WOULD NOT OTHERWISE BE ABLE TO COMPLETE. TWO "LINDA MEALY AWARDS" WERE GRANTED TO JUNIOR SCIENTISTS FOR NEW RESEARCH OF HIGH QUALITY IN HUMAN ETHOLOGY. TWO "BEST STUDENT PAPER" AWARDS WERE AWARDED FOR PAPERS PUBLISHED IN THE SOCIETY'S FLAGSHIP JOURNAL, HUMAN ETHOLOGY.VOLUME 37 OF THE SOCIETY'S FLAGSHIP JOURNAL, HUMAN ETHOLOGY WAS PUBLISHED. THIS OPEN-ACCESS, PEER-REVIEWED PUBLICATION INCLUDED 1 BOOK REVIEW, 1 COMMENTARY PIECE, A BRIEF REPORT, AND 3 FULL-LENGTH EMPIRICAL RESEARCH ARTICLES. ISHE INCURS THE HOSTING AND EDITORIAL COSTS OF MAINTAINING AN OPEN-ACCESS JOURNAL RATHER THAN TRANSFERRING ANY OF THAT COST TO AUTHORS (VIA ARTICLE PROCESSING CHARGES COMMON TO MANY PUBLICATIONS) IN ORDER TO FACILITATE AND ENCOURAGE SUBMISSIONS FROM RESEARCHERS AT UNDER-FUNDED INSTITUTIONS AND/OR STUDENT OR EARLY CAREER RESEARCHERS WHO DO NOT HAVE SUPPORT FUNDS. IT IS IMPORTANT TO ISHE THAT THEY REMOVE BARRIERS TO THE DISSEMINATION OF SCIENTIFIC KNOWLEDGE.THE ANNUAL CONFERENCE WAS HELD IN WURZBURG, GERMANY. THIS SCIENTIFIC MEETING ATTRACTED APPROXIMATELY 110 ATTENDEES FROM 5 DIFFERENT CONTINENTS. THE SCIENTIFIC PROGRAM INCLUDED OVER 50 CONFERENCE TALKS FROM SCHOLARS WORLD-WIDE, 30 POSTER PRESENTATIONS (PRIMARILY FROM STUDENT RESEARCHERS), A PRE-CONFERENCE WORKSHOP ON THE USE OF NEUROIMAGING IN NATURALISTIC RESEARCH, AND 5 INVITED KEYNOTE/PLENARY TALKS FROM LEADING RESEARCHERS IN THE FIELD. STUDENT PARTICIPATION IN THE MEETING WAS SUBSIDIZED BY THE SOCIETY.</Desc>

      <FactsAndCircumstancesTestTxt>Current Year Facts and Circumstances: he organization is dedicated to advancing the field of human ethology and providing opportunities for professionals and students interested in this area of study. While the organization does not satisfy the 33.33% public support test due to a substantial bequest of publicly-traded securities received years ago that produces ongoing investment income, it can still qualify as a public charity under the alternative 10% facts and circumstances test as provided in IRC Section 170(b)(1)(A)(vi) and elaborated in Treas. Reg. 1.170A-9(f).Specifically, the organization receives 11.72% of its total support for the subject tax year and 19.5% in the prior tax year from public sources that is, membership fees from professionals and students around the world. The organization uses its investment income to subsidize membership fees in order to advance its charitable mission of promoting education and engagement in human ethology by removing cost barriers for new members interested in the field. Its membership is open to all those interested, including students and professionals in low-income areas across the world.In addition, an analysis of the five factors for determining public charity status under this test demonstrates that the organization possesses the characteristics of a publicly supported organization:- The organization receives over 10% of its total support from public sources in both the subject year (11.72%) and prior year (19.50%). This level of public support helps clearly establish its status as a public charity.- The organizations governing body is comprised of professionals and scholars in the field, representing expertise and diverse perspectives rather than any private interests.- The organization provides facilities, services, and activities benefitting the general public through scholarships, a scholarly bulletin, conferences, and advancement of human ethology as a field of study. The public actively participates through membership and conference attendance.- As a membership organization, the organization appeals to a broad segment of the public interested in human ethology, offers discounted dues, and solicits members broadly.Based on satisfying these factors in an analysis of all the relevant facts and circumstances this year, the organization qualifies for public charity status under the 10% test pursuant to applicable law, even though it does not meet the 33.33% public support test on a 5-year aggregate basis. The organization continues to operate exclusively for educational and charitable purposes benefitting the general public. Prior Year Facts and Circumstances: The organization is dedicated to advancing the field of human ethology and providing opportunities for professionals and students interested in this area of study. While the organization does not satisfy the 33.33% public support test due to a substantial bequest of publicly-traded securities received years ago that produces ongoing investment income, it can still qualify as a public charity under the alternative 10% facts and circumstances test as provided in IRC Section 170(b)(1)(A)(vi) and elaborated in Treas.
