Modeling Regional Radicarbon Trends: A Case Study From The East Texas Woodland Period, Robert Z. Selden Jr. Jan 2012

Modeling Regional Radicarbon Trends: A Case Study From The East Texas Woodland Period, Robert Z. Selden Jr.

CRHR: Archaeology

The East Texas Radiocarbon Database contributes to an analysis of tempo and place for Woodland era (~500 BC–AD 800) archaeological sites within the region. The temporal and spatial distributions of calibrated 14C ages (n = 127) with a standard deviation (ΔT) of 61 from archaeological sites with Woodland components (n = 51) are useful in exploring the development and geographical continuity of the peoples in east Texas, and lead to a refinement of our current chronological understanding of the period. While analysis of summed probability distributions (SPDs) produces less than significant findings due to sample size, they are used …


The East Texas Caddo: Modeling Tempo And Place, Robert Z. Selden Jr., Timothy K. Perttula Jan 2012

The East Texas Caddo: Modeling Tempo And Place, Robert Z. Selden Jr., Timothy K. Perttula

CRHR: Archaeology

Analysis of the Caddo sample (n=889 dates) from the East Texas radiocarbon database is used to establish the tempo and place of Caddo era (ca. A.D. 800-1680) archaeological sites, site clusters, and communities across the region. The temporal and spatial distribution of radiocarbon ages from settlements, mound centers, and cemeteries across the region have utility in exploring the development and geographical continuity of the Caddo peoples; establishing the specific times when areas were abandoned or population sizes diminished; and defining times and areas illustrating an intensification in mound center construction and large cemeteries became a focus of community social practices.


Transboundary Management Of Transitional Waters – Code Of Conduct And Good Practice Examples, Henrik Nilsson, Ramūnas Povilanskas, Nardine Stybel Jan 2012

Transboundary Management Of Transitional Waters – Code Of Conduct And Good Practice Examples, Henrik Nilsson, Ramūnas Povilanskas, Nardine Stybel

ARTWEI

Transitional waters have the ecological peculiarity of being both very fragile and resilient at the same time. The degradation of the transitional waters and the decline of their economic value arise from the excessive use of the resources, external input of pollutants mostly brought by large tributaries and from the mismanagement of the adjacent areas. The EU Water Framework Directive has accelerated the transboundary co-operation and development of spatially integrative management approaches in the south Baltic transitional waters. A high-level political committment in countries sharing a transitional water body, a professional agency, a stakeholders‘ forum and regular funding is the …


Diversified Farming Systems: An Agroecological, Systems-Based Alternative To Modern Industrial Agriculture, Claire Kremen, Alastair Iles, Christopher M. Bacon Jan 2012

Diversified Farming Systems: An Agroecological, Systems-Based Alternative To Modern Industrial Agriculture, Claire Kremen, Alastair Iles, Christopher M. Bacon

Environmental Studies and Sciences

This Special Issue on Diversified Farming Systems is motivated by a desire to understand how agriculture designed according to whole systems, agroecological principles can contribute to creating a more sustainable, socially just, and secure global food system. We first define Diversified Farming Systems (DFS) as farming practices and landscapes that intentionally include functional biodiversity at multiple spatial and/or temporal scales in order to maintain ecosystem services that provide critical inputs to agriculture, such as soil fertility, pest and disease control, water use efficiency, and pollination. We explore to what extent DFS overlap or are differentiated from existing concepts such as …


Food Security And Smallholder Coffee Production: Current Issues And Future Directions, Martha Caswell, V. Ernesto Méndez,, Christopher M. Bacon Jan 2012

Food Security And Smallholder Coffee Production: Current Issues And Future Directions, Martha Caswell, V. Ernesto Méndez,, Christopher M. Bacon

Environmental Studies and Sciences

In recent years, there has been growing discussion within the specialty coffee industry about the preva- lence of seasonal food insecurity in coffee growing communities. The idea that coffee producers lack re- sources to feed themselves and their families flies in the face of Fair Trade and other sustainable coffee ini- tiatives, which were designed to ensure a viable livelihood and improved conditions for small-scale coffee farmers around the world. Though these certifications represent an important step toward delivering better prices to farmers, they are inadequate tools to stand alone against the formidable and entrenched barriers faced by this population. …

Understanding The Contribution Of Wilderness-Based Educational Experiences To The Creation Of An Environmental Ethic In Youth, Trever Waage, Karen Paisley, John Gookin

Research in Outdoor Education

The purpose of this exploratory study was to deepen our understanding of the ways in which a wilderness-based educational experience may serve as a significant life experience and how that experience may impact the development of an environmental ethic in youth. Students on 30-day courses from the National Outdoor Leadership School (NOLS) were asked to respond to the question, “Did your NOLS experience make an impact on your environmental ethics? If so, how?” The responses of 771 students indicated that a 30-day NOLS course did, in fact, positively influence both cognitive and emotional aspects of participants' environmental ethics and shared …


A Qualitative Exploration Of Sense Of Community Through Reflective Journals During Wilderness Outdoor Education Curricula, Garrett Hutson, Lynn Anderson, Mary Breunig, Tim O'Connell, Sharon Todd, Anderson Young Jan 2012

A Qualitative Exploration Of Sense Of Community Through Reflective Journals During Wilderness Outdoor Education Curricula, Garrett Hutson, Lynn Anderson, Mary Breunig, Tim O'Connell, Sharon Todd, Anderson Young

Research in Outdoor Education

There has been repeated encouragement in the literature for researchers to examine the various mechanisms that make up group experiences in outdoor education contexts. As a result, positive sense of community is often one of the implicit or explicit goals of programs and organizations that utilize outdoor settings to deliver educational and/or therapeutic programs. The purpose of this study was to understand how participants understand and experience sense of community formation during participation on outdoor education curricula (OEC) programs. Qualitative data, in the form of 124 participant trip journals, were analyzed and revealed two core themes illuminating sense of community …


The Role And Importance Of Program Quality In Outdoor Adventure Programs For Youth: Examining Program Quality Indicators As Predictors Of Outcome Achievement Among Nols Participants, Rachel Collins, Jim Sibthorp, John Gookin, Scott Schumann Jan 2012

The Role And Importance Of Program Quality In Outdoor Adventure Programs For Youth: Examining Program Quality Indicators As Predictors Of Outcome Achievement Among Nols Participants, Rachel Collins, Jim Sibthorp, John Gookin, Scott Schumann

Research in Outdoor Education

Youth outdoor and adventure programs are increasingly being expected to provide evidence that their programs are effective in achieving outcomes. While this is an important goal, participant outcomes are difficult to program for as they are influenced by many variables including the active role of the participant, the leader, the social and physical environments, and a myriad of contextual variables. However, program quality manifests at the point of service, and thus remains malleable by the program. Results of this study highlight the importance of program quality indicators on participant development and more specifically, which elements of program quality are most …

Enhancing Social Support Through Adventure Education: The Case Of Fathers And Sons, Curt Davidson, Alan Ewert Jan 2012

Enhancing Social Support Through Adventure Education: The Case Of Fathers And Sons, Curt Davidson, Alan Ewert

Research in Outdoor Education

Adventure education (AE) research often utilizes social support as an outcome variable associated with participation in extended outdoor adventure trips. Social support is defined as “the degree to which individuals have access to social resources, in the form of relationships, on which they can rely” (Johnson & Sarason, 1979). Using an adventure-based program offering a treatment specifically designed for father and son participants, significant changes in pre-post comparison scores on the variables of trust, communication, and social support were reported for both fathers and sons. Qualitative analysis revealed four major themes: communication enhancement, instructor influence, course components, and shared time. …


Semantics Of Perception: Towards A Semantic Web Approach To Machine Perception, Cory Andrew Henson, Amit P. Sheth Jan 2012

Semantics Of Perception: Towards A Semantic Web Approach To Machine Perception, Cory Andrew Henson, Amit P. Sheth

Kno.e.sis Publications

The acts of observation and perception provide the building blocks for all human knowledge (Locke, 1690); they are the processes from which all ideas are born; and the sole bond connecting ourselves to the world around us. Now, with the advent of sensor networks capable of observation, this world may be directly accessible to machines. Missing from this vision, however, is the ability of machines to glean semantics from observation; to apprehend entities from detected qualities; to perceive. The systematic automation of this ability is the focus of machine perception -- the ability of computing machines to sense and interpret …

Producing Edible Landscapes In Seattle's Urban Forest, Rebecca J. Mclain, Melissa R. Poe, Patrick T. Hurley, Joyce Lecompte, Marla R. Emery

Environment and Sustainability Faculty Publications

Over the next decades, green infrastructure initiatives such as tree planting campaigns, and ecological restoration will dramatically change the species composition, species distribution and structure of urban forests across the United States. These impending changes are accompanied by a demand for urban public spaces where people can engage in practices such as gleaning, gardening, and livestock production. This article analyzes the institutional framework that undergirds efforts in Seattle, Washington to normalize the production and use of edible landscapes. We focus attention on the role of grassroots fruit gleaning groups and highlight their bridging function between Seattle's agriculture and forestry policy …

Tackling Tax Evasion: Transfer Price Manipulation, Extractive Natural Resources And A Strategy For The Southern African Customs Union, Patrick Grant Mclennan Jan 2012

Tackling Tax Evasion: Transfer Price Manipulation, Extractive Natural Resources And A Strategy For The Southern African Customs Union, Patrick Grant Mclennan

Electronic Theses and Dissertations

An increase in the number of multinational enterprises (MNEs) has increased the attention on cross-border challenges, such as transfer price manipulation (TPM). TPM is a development issue - it undermines institutions as well as siphons money from government revenues that could be directed towards programs for human development. Pervasive corruption in the natural resource sector supports an environment where TPM can flourish. This paper develops a strategy for combating TPM within the countries of the Southern African Customs Union. It does this by 1) defining the terrain of illicit flows, both generally and specifically to the abuse of transfer pricing …


The Arctic Game, Sarah E. Nuernberger Jan 2012

The Arctic Game, Sarah E. Nuernberger

Electronic Theses and Dissertations

Since outsiders first visited the Arctic, they have believed in man's ability to conquer the region. Today's Arctic conquest is not one of heroic exploration, but rather one of ownership and exploitation. This paper illustrates contestation in the Arctic through the metaphor of a game, with attendant prizes, players, and rules. It focuses on how to prevent the future destruction of the Arctic given the interactions of the Arctic's landscape, prizes, players, and current management frameworks. In the wake of renewed resource exploitation and escalating climate change impacts, the current frameworks and mindsets are inadequate to support the precarious balance …

A Scalable Distributed Syntactic, Semantic And Lexical Language Model, Ming Tan, Wenli Zhou, Lei Zheng, Shaojun Wang Jan 2012

A Scalable Distributed Syntactic, Semantic And Lexical Language Model, Ming Tan, Wenli Zhou, Lei Zheng, Shaojun Wang

Kno.e.sis Publications

This paper presents an attempt at building a large scale distributed composite language model that is formed by seamlessly integrating an n-gram model, a structured language model, and probabilistic latent semantic analysis under a directed Markov random field paradigm to simultaneously account for local word lexical information, mid-range sentence syntactic structure, and long-span document semantic content. The composite language model has been trained by performing a convergent N-best list approximate EM algorithm and a follow-up EM algorithm to improve word prediction power on corpora with up to a billion tokens and stored on a supercomputer. The large scale distributed composite …


The Journal’S The Thing: Teaching Natural History And Nature Writing In Baja California Sur, John S. Farnsworth, Christopher Beatty Jan 2012

The Journal’S The Thing: Teaching Natural History And Nature Writing In Baja California Sur, John S. Farnsworth, Christopher Beatty

Environmental Studies and Sciences

The skills of making informed observations, synthesizing those observations, and communicating them effectively are central to the naturalist. Developing university courses that optimize instruction in these skills simultaneously can, however, be a challenge. Here we describe a program at Santa Clara University comprised of two integrated co-requisite courses, Writing Natural History (ENVS 142) and The Natural History of Baja (BIOL/ENVS 144). Lectures through the 10-week winter quarter expand students’ knowledge of the ecosystems and biodiversity of the Baja Peninsula and help them to develop descriptive writing skills. The courses culminate in a ten-day expedition to the Baja Peninsula and Isla …


Alignment-Based Querying Of Linked Open Data, Amit Krishna Joshi, Prateek Jain, Pascal Hitzler, Peter Z. Yeh, Kunal Verma, Amit P. Sheth, Mariana Damova Jan 2012

Alignment-Based Querying Of Linked Open Data, Amit Krishna Joshi, Prateek Jain, Pascal Hitzler, Peter Z. Yeh, Kunal Verma, Amit P. Sheth, Mariana Damova

Kno.e.sis Publications

The Linked Open Data (LOD) cloud is rapidly becoming the largest interconnected source of structured data on diverse domains. The potential of the LOD cloud is enormous, ranging from solving challenging AI issues such as open domain question answering to automated knowledge discovery. However, due to an inherent distributed nature of LOD and a growing number of ontologies and vocabularies used in LOD datasets, querying over multiple datasets and retrieving LOD data remains a challenging task. In this paper, we propose a novel approach to querying linked data by using alignments for processing queries whose constituent data come from heterogeneous …
