Debe Ser Dirigida: Theories Of Community Organizing For Research Management In The Context Of Rural Ecuador, Meghan Edwards Apr 2022

Debe Ser Dirigida: Theories Of Community Organizing For Research Management In The Context Of Rural Ecuador, Meghan Edwards

Student Symposium

This research analysis and literature review discusses the factors that mobilize individuals to take an active role in community-led resource management. After reviewing major contemporary theories of resource management such as Elinor Ostrom's polycentric theory, CPR theories, and Arnstein's ladder, the essay then applies these theories to the context of the Quijos Valley in Ecuador, where the author conducted informal interviews with community members both involved and not-involved in managing fragile soil ecosystems. The literature review considers the idea that individuals are more likely to take an active role in research management when there are strong community bonds, and highlights …


A Quantitative Analysis Of The Effects Of Urbanization, Mesophication And Prescribed Burns On Oak Woodlands In The Chicago Metropolitan Area, Chad Populorum May 2018

A Quantitative Analysis Of The Effects Of Urbanization, Mesophication And Prescribed Burns On Oak Woodlands In The Chicago Metropolitan Area, Chad Populorum

Celebration of Learning

Urban expansion has had devastating impacts on forest ecosystems, especially within the past century. Human attempts to dominate nature have diminished natural disturbance regimes, which have maintained the biodiversity and historic composition of these ecosystems. Fires have been a prominent force in maintaining the structure of oak, hickory and other heliophytic (sun loving and fire-adapted) forest systems. Human induced fire suppression has led to mesophication across North America. Mesophication is the transition from drier conditions with open canopies to wetter conditions with closed canopies. These new conditions decrease the survival rates of these important species and begin to favor mesophytic …


Networks - Ii: Optimal Fractional Frequency Reuse (Ffr) And Resource Allocation In Multiuser Ofdma System, Naveed Ul Hassan, Mohamad Assaad Sep 2009

Networks - Ii: Optimal Fractional Frequency Reuse (Ffr) And Resource Allocation In Multiuser Ofdma System, Naveed Ul Hassan, Mohamad Assaad

International Conference on Information and Communication Technologies

In this paper we determine the optimal fractional frequency reuse (FFR) and resource allocation in OFDMA system. Since the users at the cell edge are more exposed to inter-cell interference therefore each cell is partitioned into two regions; inner region and outer region. We determine the optimal FFR factor for the outer region, bandwidth assigned to each region and subcarrier and power allocation to all the users in the cell. The problem is formulated as sum-power minimization problem subject to minimum rate constraints in both the regions. This is a mixed linear integer programming problem which is relaxed into a …


Wireless Networks: Spert: A Stateless Protocol For Energy-Sensitive Real-Time Routing For Wireless Sensor Network, Sohail Jabbar, Abid Ali Minhas, Raja Adeel Akhtar Aug 2009

Wireless Networks: Spert: A Stateless Protocol For Energy-Sensitive Real-Time Routing For Wireless Sensor Network, Sohail Jabbar, Abid Ali Minhas, Raja Adeel Akhtar

International Conference on Information and Communication Technologies

Putting constraints on performance of a system in the temporal domain, some times turns right into wrong and update into outdate. These are the scenarios where apposite value of time inveterate in the reality. But such timing precision not only requires tightly scheduled performance constraints but also requires optimal design and operation of all system components. Any malfunctioning at any relevant aspect may causes a serious disaster and even loss of human lives. Managing and interacting with such real-time system becomes much intricate when the resources are limited as in wireless sensor nodes. A wireless sensor node is typically comprises …


Implementation And Analysis Of Cmmi's Configuration Management Process Area; Applicable To "Defined" Level - 3, Ahmad Luqman Aug 2005

Implementation And Analysis Of Cmmi's Configuration Management Process Area; Applicable To "Defined" Level - 3, Ahmad Luqman

International Conference on Information and Communication Technologies

Enterprise Resource Planner (ERP) is a strategically important tool as integrated business application for long-term success in an increasingly competitive global market. This system requires the integration of data and business processes across the whole enterprise. In order to develop a good quality product there is a need of applying proper model. It becomes more costly in terms of training, appraisals, and improvement activities while applying multiple models that are not integrated within and across an organization. Where as Capability Maturity Model Integration is a set of integrated models that successfully addresses multiple disciplines and has integrated training support. Objective …


Keynote: Emerging Era Of Cooperative Empowerment: Grid, Peer-To-Peer, And Community Computing, Dr. Javed I. Khan Aug 2005

Keynote: Emerging Era Of Cooperative Empowerment: Grid, Peer-To-Peer, And Community Computing, Dr. Javed I. Khan

International Conference on Information and Communication Technologies

In this paper we discuss an emerging trend in high performance computing-the social or community computing. The emergence of screensaver computing, grid computing, peer-to-peer systems, and their demonstrated ability to garner computing power as potent as the supercomputers seems to be auspicious. In this paper we discuss the new phenomenon of community computing-including their potential applications in solving a new set of grand challenge problems. We also discuss the previously uncharted technological challenges architects of these new paradigms are addressing.
