At the 2009 Annual Meeting of the Ecological Society of America, investigators of ecosystem science and biogeochemistry gathered in a series of sessions sponsored by the National Science Foundation to examine what is known about the coupling of chemical elements in biochemistry and thus in global biogeochemical cycles. As an introduction to the topic, this paper offers some philosophical thoughts about the origins and implications of coupled biogeochemical cycles on Earth. The chemical characteristics of Earth have carried the imprint of biology since the first appearance of life more than 3.5 billion years ago. Movements of about 30 chemical elements essential to life are coupled, so that the behavior of one element can often be used to predict the behavior of other elements - in both the natural and human-perturbed settings of the world. The coupling of biochemical elements stems from basic stoichiometry (the relative quantities of chemical elements in living biomass), the oxidation-reduction or "redox" reactions (in which one substance is oxidized [loses electrons] and another is reduced [gains electrons]) of metabolic activity, and chelation (in which a metal ion binds to an organic compound). Many anthropogenic environmental problems - climate change, eutrophication, acid precipitation, metal pollution - originate from the release of non-stoichiometric and toxic quantities of chemical elements to the environment. Geoengineering pro-posals as solutions to certain global environmental problems must be consistent with the underlying constraints of coupled biogeochemical cycles. Biogeochemistry has much to offer to policy makers, and biogeochemists must contribute to current deliberations about how to solve environmental problems. [ABSTRACT FROM AUTHOR]

As a part of the 2000-01 American Dental Education Association (ADEA) Leadership Institute, the Leadership Institute Fellows conducted a faculty development workshop for department chairpersons and program directors during the 2001 ADEA Annual Session. A central premise of the workshop was that successful chairpersons and program directors are both effective leaders and effective managers and that leadership and management involve complementary activities. The workshop was casebased. The ADEA Leadership Institute Fellows developed the cases and led roundtable discussions of each case. A group facilitator led large group debriefings to apply management and leadership theory to each case. The purpose of this paper is to review leadership challenges and management concepts as they were applied in a case-based faculty development workshop. The program was structured to address leadership challenges relating to managing people, mission management, conflict recognition, and conflict management. The cases were developed to relate management theories to situations in academic administration. The situations were designed to encourage debate from numerous perspectives. Each case presented general dilemmas that could be addressed from the vantage point of the dean, chair, or individual faculty member. Reinforcing discussion followed and included identification of central issues, key management concepts, and action alternatives. Because of the breadth of possible discussion, group case analyses at the workshop and in the appended case reviews explore only one perspective. This overview article introduces concepts of leadership and management that provide the foundation for analysis of three case studies that follow. These cases address common leadership and management issues in academic dentistry through three typical cases: the frustrated faculty member (case 1), the misdirected faculty member (case 2), and the faculty member stuck in the middle (case 3).

Information about several papers discussed at the U.S. National Institutes of Health Consensus Development Conference on Diagnosis and Management of Dental Caries Throughout Life on March 26-28, 2001 is presented. Topics include the management of dental caries, risk factors of teeth diseases, and effect of sugar consumption to teeth. The conference featured several notable physicians including Dr. George Stookey, Brian Burt, and Susan Reisine.

Information about several papers discussed at a meeting of the United Chapters of the Alpha Kappa Delta in Ohio. Officers each chapter have suggested initiation ritual for member of the said fraternity. The meeting featured several representatives of each chapter including Catherine S. Baker of Alpha Missouri.

Information about several papers discussed at the meetings of various chapters of the United Chapters of the Alpha Kappa Delta in the U.S. is presented. Officers of each chapters are always concerned on the growth of the fraternity, election of new officers and acceptance of new members. The meetings featured several speakers including Dr. Leon Ellis.

The article presents the minutes for the meeting of Alpha Kappa Delta society which was conducted on September 10, 1954 at the University of Illinois in the U.S. The suggestion to expand the society's official publication "The Alpha Kappa Deltan" and the additional of prizes for the best papers from undergraduate and graduate students were not approved by the members. The conference had also discussed the disposition of the society's surplus funds.
