Chan An Ancient Maya Farming Community
No full textThe farming community of Chan thrived for over twenty centuries, surpassing the longevity of many larger Maya urban centers. Between 800 BC and 1200 AD it was a major food production center, and this collection of essays reveals the important role played by Maya farmers in the development of ancient Maya society. Chan offers a synthesis of compelling and groundbreaking discoveries gathered over ten years of research at this one archaeological site in Belize. The contributors develop three central themes, which structure the book. They examine how sustainable farming practices maintained the surrounding forest, allowing the community to exist for two millennia. They trace the origins of elite Maya state religion to the complex religious belief system developed in small communities such as Chan. Finally, they describe how the group-focused political strategies employed by local leaders differed from the highly hierarchical strategies of the Classic Maya kings in their large cities. In breadth, methodology, and findings, this volume scales new heights in the study of Maya society and culture.Cover -- Title -- Copyright -- Contents -- List of Figures -- List of Tables -- Foreword -- Acknowledgments -- 1.

Vickers-Chan-7thGraders_Multiplex_Social .zip
No full textThe dataset representing the multiplex social network in a school in Victoria, Australia.
If you use this dataset in your work either for analysis or for visualization, you should acknowledge/cite the following papers:
Representing Classroom Social Structure. Melbourne: Victoria Institute of Secondary Education
M. Vickers and S. Chan, (1981)
The data were collected by Vickers from 29 seventh grade students in a school in Victoria, Australia. Students were asked to nominate their classmates on a number of relations including the following three (layers):
1. Who do you get on with in the class?
2. Who are your best friends in the class?
3. Who would you prefer to work with?
Students 1 through 12 are boys and 13 through 29 are girls.
There are 29 nodes in total, labelled with integer ID between 1 and 29, with 740 connections.
The multiplex is directed and unweighted, stored as edges list in the file

Dynamic Geometric Data Structures via Shallow Cuttings
No full textWe present new results on a number of fundamental problems about dynamic geometric data structures:
1) We describe the first fully dynamic data structures with sublinear amortized update time for maintaining (i) the number of vertices or the volume of the convex hull of a 3D point set, (ii) the largest empty circle for a 2D point set, (iii) the Hausdorff distance between two 2D point sets, (iv) the discrete 1-center of a 2D point set, (v) the number of maximal (i.e., skyline) points in a 3D point set. The update times are near n^{11/12} for (i) and (ii), n^{7/8} for (iii) and (iv), and n^{2/3} for (v). Previously, sublinear bounds were known only for restricted "semi-online" settings [Chan, SODA 2002].
2) We slightly improve previous fully dynamic data structures for answering extreme point queries for the convex hull of a 3D point set and nearest neighbor search for a 2D point set. The query time is O(log^2n), and the amortized update time is O(log^4n) instead of O(log^5n) [Chan, SODA 2006; Kaplan et al., SODA 2017].
3) We also improve previous fully dynamic data structures for maintaining the bichromatic closest pair between two 2D point sets and the diameter of a 2D point set. The amortized update time is O(log^4n) instead of O(log^7n) [Eppstein 1995; Chan, SODA 2006; Kaplan et al., SODA 2017]
Andy Chan oral history interview and transcript
No full textThis recording and transcript form part of a collection of oral history interviews conducted by the Chao Center for Asian Studies at Rice University. This collection includes audio recordings and transcripts of interviews with Asian Americans native to or living in Houston.Andy Chan was born in Queens, New York City in 1965. He moved to Houston in 1971 because of his father’s graphic artist career at Shell Oil Company. After studying environmental design at Texas A&M University for a year, Mr. Chan decided to go home to help his parents’ various businesses in the restaurant and graphics industries. He transferred to Texas Southern University and graduated while still working 40 hours a week in his father’s company. Eventually, Mr. Chan started his own business, Alpha Omega Graphics, which focused on the more cutting-edge side of desktop publishing.
After having children, Mr. Chan decided to sell his printing business and do more service within public education and the Houston School Districts. He served as PTO President for various elementary and middle schools, and currently serves on the District Advisory Committee. After a successful project renovating Fire Truck Park in Southside Place, Mr. Chan decided to run for City Council, and was also appointed Mayor Pro Tem in 2016 during Hurricane Harvey. This past May, he won the election for Mayor of the City of Southside Place. Mr. Chan is the first American Born Chinese to become Mayor in the state of Texas.
In this interview, Mr. Chan discusses his upbringing in New York City and Houston, his entrepreneurial endeavors throughout and after college, and his work in public education and service. He also discusses the importance of giving back to one’s community, his Asian-American identity, and his family
Dynamic Geometric Connectivity in the Plane with Constant Query Time
No full textWe present the first fully dynamic connectivity data structures for geometric intersection graphs achieving constant query time and sublinear amortized update time for many classes of geometric objects in 2D . Our data structures can answer connectivity queries between two objects, as well as "global" connectivity queries (e.g., deciding whether the entire graph is connected). Previously, the data structure by Afshani and Chan (ESA'06) achieved such bounds only in the special case of axis-aligned line segments or rectangles but did not work for arbitrary line segments or disks, whereas the data structures by Chan, Pătraşcu, and Roditty (FOCS'08) worked for more general classes of geometric objects but required n^{Ω(1)} query time and could not handle global connectivity queries.
Specifically, we obtain new data structures with O(1) query time and amortized update time near n^{4/5}, n^{7/8}, and n^{20/21} for axis-aligned line segments, disks, and arbitrary line segments respectively. Besides greatly reducing the query time, our data structures also improve the previous update times for axis-aligned line segments by Afshani and Chan (from near n^{10/11} to n^{4/5}) and for disks by Chan, Pătraşcu, and Roditty (from near n^{20/21} to n^{7/8})
Mme Chan et M. Chow à Singapour
No full text M. Chow, oppressé par l’atmosphère étouffante et les commérages de Hong-Kong, est parti pour Singapour, laissant Mme Chan seule à Hong-Kong. Cette séquence dévoile progressivement une visite de Mme Chan à Singapour dans l’appartement de M. Chow, sans que celui-ci ne le sache. S’il s’agit d’une tentative de retrouvailles en dehors de l’étouffante Hong-Kong, Singapour se révèle tout aussi exiguë et impropre à leur amour et cette dernière tentative d’union se solde par le constat de l’impossi..
