Leadership, the logic of sufficiency and the sustainability of education

The notion of sufficiency has not yet entered mainstream educational thinking, and it still has to make its mark upon educational leadership. However, a number of related concepts – particularly those of sustainability and complexity theory – are beginning to be noticed. This article examines these two concepts and uses them to critique the quasi-economic notion of efficiency, before arguing that the concept of sufficiency arises naturally from this discussion. This concept, originally derived from environmental thinking, has both metaphorical and practical impact for educational organizations and their leadership. An examination of three possible meanings suggests that while an embrace of an imperative concept of sufficiency seems increasingly necessary, its adoption would probably lead to a number of other problems, as it challenges some fundamental societal values and assumptions. Nevertheless, the article argues that these need to be addressed for the sake of both sustainable leadership and a sustainable planet

Intellectual Property and Opportunities for Food Security in the Philippines

By 2050, the Philippine population is projected to increase by as much as 41 percent, from 99.9 million to nearly 153 million people. Producing enough food for such an expanding population and achieving food security remain a challenge for the Philippine government. This paper argued that intellectual property rights (IPR) can play a key role in achieving the nation’s current goal to be food-secure and provided examples to illustrate that the presence of sound intellectual property (IP) helps foster research, development, and deployment of agricultural innovations. This paper also offered key recommendations about how the IP system can be further leveraged to enable access, creation, and commercialization of new and innovative agricultural practices and technologies to enhance the nation’s agricultural productivity, meet rice self-sufficiency, and sustain food security

Grass clover ley species, variety selection and management

Grass clover leys form the basis of most organic farming systems yet the selection of seed mixtures is often founded on tradition or cost. Based on a review of recent and past research this review provides a wealth of information on grass and legume species and varieties, mixture selection, ley establishment and pasture management. The objective of the Grass Clover Ley research review are: 1. To identify all the relevant research undertaken 2. Collate the results of the research 3. Draw on farm and commercial experience 4. Summarise the practical implications of the research for organic farming 5. Facilitate access to the results of research to advisers in a form which allows easy transfer to farmers. The report presents key conclusions about the choice of legume and gras species and varietes, the management of swards and their role for fertility building

Application of new probabilistic graphical models in the genetic regulatory networks studies

This paper introduces two new probabilistic graphical models for reconstruction of genetic regulatory networks using DNA microarray data. One is an Independence Graph (IG) model with either a forward or a backward search algorithm and the other one is a Gaussian Network (GN) model with a novel greedy search method. The performances of both models were evaluated on four MAPK pathways in yeast and three simulated data sets. Generally, an IG model provides a sparse graph but a GN model produces a dense graph where more information about gene-gene interactions is preserved. Additionally, we found two key limitations in the prediction of genetic regulatory networks using DNA microarray data, the first is the sufficiency of sample size and the second is the complexity of network structures may not be captured without additional data at the protein level. Those limitations are present in all prediction methods which used only DNA microarray data.Comment: 38 pages, 3 figure

Policy Options for Assisting Child SSI Recipients in Transition

The transition process for a child Supplemental Security Income (SSI) recipient nearing the age of 18 can be quite complicated. From a programmatic standpoint, all child SSI recipients have their eligibility redetermined under the adult SSI disability requirements at age 18. Potentially more important, many child SSI recipients are also at the age when they must prepare for life beyond secondary school. The choices made during this important transition could have long-term implications for a child's future employment prospects, particularly given the typically long durations of participation and strong work disincentives associated with SSI participation. The purpose of our analysis is to examine concerns related to this transition process and suggest policy options for consideration by the Social Security Administration's (SSA) Ticket Advisory Panel. Our findings are based on an extensive literature review of programs that serve child SSI recipients and semi-structured interviews with experts familiar with the problems facing youth during this transition. In previous reports, the Ticket Advisory Panel has suggested expanding eligibility for the Ticket program to child SSI recipients age 17 to 18 as one possible mechanism for improving independent living options for this population (Ticket to Work and Work Incentives Advisory Panel 2001). We build off this initial suggestion by examining other possible mechanisms for improving independent living options for "transition age" (i.e., youth nearing age 18) child SSI recipients

EcoBlock: Grid Impacts, Scaling, and Resilience

Widespread deployment of EcoBlocks has the potential to transform today's electricity system into one that is more resilient, flexible, efficient and sustainable. In this vision, the system will consist of self- su cient, renewable-powered, block-scale entities that can deliberately adjust their net power exchange and can optimize performance, maintain stability, support each other, or disconnect entirely from the grid as needed. This report is intended as an independent analysis of the potential relationships, both constructive and adverse, between EcoBlocks and the grid
