Boethius and the Block Universe: Physical and Metaphysical Considerations of Time

In this exploration of the nature of time, the author shows that more than a superficial belief in a creator God invites the person of faith to engage with some of the unsettling questions presented by modern physics and cosmology. He considers how human beings study and measure time, and he also treats how we experience time as creatures \"caught\" in its passage, and the emotions evoked by that experience. The various possible paths of the future of the universe are provocative subjects for theological treatment

Evaluating watershed management projects:

Watershed projects play an increasingly important role in managing soil and water resources throughout the world. Research is needed to ensure that new projects draw upon lessons from their predecessors' experiences. However, the technical and social complexities of watershed projects make evaluation difficult. Quantitative and qualitative evaluation methods, which traditionally have been used separately, both have strengths and weaknesses. Combining them can make evaluation more effective, particularly when constraints to study design exist. This paper presents mixed-methods approaches for evaluating watershed projects. A recent evaluation in India provides illustrations.

Impacts of the Hutan Kamasyarakatan Social Forestry Program in the Sumberjaya watershed, West Lampung District of Sumatra, Indonesia:

"This paper investigates the impacts of a social forestry program in Indonesia, Hutan Kamasyarakatan (HKm), based on analysis of a survey of 640 HKm and comparable non-HKm plots in the Sumberjaya watershed of southern Sumatra, and of the households operating those plots. The HKm program provides groups of farmers with secure-tenure permits to continue farming on state Protection Forest land and in exchange for protecting remaining natural forestland, planting multistrata agroforests, and using recommended soil and water conservation (SWC) measures on their coffee plantations. Using farmers' perceptions, econometric techniques, and propensity score matching, we investigated the impacts of the HKm program on perceived land tenure security, land purchase prices, farmers' investments in tree planting and SWC measures, and plot-level profits. A significant fraction of HKm group members are not aware of the program or fully aware of its requirements. Although farmers who are aware of the program perceive its strong effects on tenure security and land values, we found insignificant impacts on the actual purchase prices of plots. Nevertheless, our survey revealed that the HKm program has contributed to increased planting of timber and multipurpose trees. We did not find significant impacts on investments in SWC measures or on soil fertility management practices. HKm has had mixed impacts on profits, with timber trees reducing profitability because timber harvesting is not allowed and multipurpose nontimber trees contributing to increased profits. The policy implications of these findings are also discussed in the paper." from Author's AbstractRewards for environmental services, Land tenure contracts, Social forestry, Impact assessment, Land management,

Impacts of the Hutan Kamasyarakatan (HKm) Social Forestry Program in the Sumberjaya Watershed, West Lampung District of Sumatra

This paper assesses the economic impacts of the Hutan Kamasyarakatan (HKm) social forestry program in the Sumberjaya watershed in West Lampung District of Sumatra, Indonesia, which began in 2001 to provide farmer groups permits to use already deforested state Protection Forest (PF) land in exchange for protecting remaining forests, planting timber and agro-forestry trees in their coffee plantations, and using soil and water conservation measures. The study is based on analysis of a survey conducted in 2005 for 640 plots in the watershed, selected using a stratified random sample of land of different tenure categories, and their operator households, and surveys of communities with PF land and HKm groups in the watershed. We find that HKm permit holders are poorer on average than owners of private land, but have comparable wealth to users of other eligible PF land who have not applied or received HKm permits, and users of National Park (NP) land, which is not eligible for HKm. Compared to eligible non-participants, households with a HKm permit by 2005 have greater education, are more involved in producer organizations, and have better access to markets, roads and technical assistance. Many communities and households are not aware of the program or its requirements, including some of those in HKm groups. Program participants and applicants perceive that it substantially increases tenure security, land values, land investments and incomes. Econometric analysis and propensity score matching methods using the survey data provide only limited support for these perceptions, showing that the program had statistically insignificant impacts on land purchase values, soil and water conservation investments, soil fertility management practices, and profits. The program did significantly increase planting of timber and multi-purpose agroforestry trees, but these have offsetting impacts on profits, with multi-purpose trees contributing to higher profits and timber trees causing lower profits because timber harvesting is not allowed. These findings indicate that the program has potentially important pro-poor benefits, though realization of these benefits is limited by potential beneficiaries lack of access to necessary human and social capital, markets and technical assistance; lack of awareness about the program; and program restrictions that require planting of timber trees but prohibit timber harvesting.Resource /Energy Economics and Policy,

On the isomorphism question for complete Pick multiplier algebras

Every multiplier algebra of an irreducible complete Pick kernel arises as the restriction algebra \mv = \{f\big|_V : f \in \cM_d\}, where $d$ is some integer or $\infty$, \cM_d is the multiplier algebra of the Drury-Arveson space $H^2_d$, and $V$ is a subvariety of the unit ball. For finite $d$ it is known that, under mild assumptions, every isomorphism between two such algebras \mv and \mw is induced by a biholomorphism between $W$ and $V$. In this paper we consider the converse, and obtain positive results in two directions. The first deals with the case where $V$ is the proper image of a finite Riemann surface. The second deals with the case where $V$ is a disjoint union of varieties.Comment: 17 pages. Final version, to appear in Integral Equations and Operator Theor
