Redemption from the Inside-Out: The Power of Faith-Based Programming
Prisons are tense, cheerless, and often degrading places in which all inmates struggle to maintain their equilibrium despite violence, exploitation, lack of privacy, stringent limitations on family and community contacts, and a paucity of opportunities for meaningful education, work, or other productive activities. As a general matter, prisoners come to see prison as their home and try to make the most of the limited resources available in prison; they establish daily routines that allow them to find meaning and purpose in their prison lives, lives that might otherwise seem empty and hopeless. The resilience shown by prisoners should not be construed as an argument for more or longer prison sentences or for more punitive regimes of confinement, but rather is a reminder that human beings can find meaning in adversity. Prisons are meant to be settings of adversity but should strive to accommodate the human needs of their inhabitants and to promote constructive changes in behavior. Here, there are programmatic offerings that may provide prisoners with the hope, skills, and empowerment necessary to overcome barriers to achievement and success as human beings in any social context. A current line of inquiry has focused on faith based prison programs and the potential benefits that a deepened spiritual life might have on coping with the doing time experience, changing old lifestyles, and reducing the likelihood of people returning to prison. These points will be explored throughout this chapter
Vertical Foreclosure and International Trade Policy
We examine conditions under which a low cost vertically integrated manufacturer has an incentive to export an intermediate product to its higher cost (vertically integrated) rival rather than to vertically foreclose, fully cutting off supplies. The nature of supply conditions in the importing country, the size of an import tariff on the final good and optimal policy by the exporting country are all shown to be important for this decision. The exporting country may gain by taxing exports of the final (Cournot) product even though, under Cournot competition, an export subsidy is optimal in the absence of a market for intermediates. In this case, optimal policy also requires an export tax on intermediates, but the higher tax on final goods serves to divert sales to the more profitable market for intermediates increasing the extent of vertical supply. It is optimal to tax the export of both goods or to subsidize the export of both goods. It is never optimal to tax one and subsidize the other.
Interplay of spatial dynamics and local adaptation shapes species lifetime distributions and species-area relationships
The distributions of species lifetimes and species in space are related,
since species with good local survival chances have more time to colonize new
habitats and species inhabiting large areas have higher chances to survive
local disturbances. Yet, both distributions have been discussed in mostly
separate communities. Here, we study both patterns simultaneously using a
spatially explicit, evolutionary community assembly approach. We present and
investigate a metacommunity model, consisting of a grid of patches, where each
patch contains a local food web. Species survival depends on predation and
competition interactions, which in turn depend on species body masses as the
key traits. The system evolves due to the migration of species to neighboring
patches, the addition of new species as modifications of existing species, and
local extinction events. The structure of each local food web thus emerges in a
self-organized manner as the highly non-trivial outcome of the relative time
scales of these processes. Our model generates a large variety of complex,
multi-trophic networks and therefore serves as a powerful tool to investigate
ecosystems on long temporal and large spatial scales. We find that the observed
lifetime distributions and species-area relations resemble power laws over
appropriately chosen parameter ranges and thus agree qualitatively with
empirical findings. Moreover, we observe strong finite-size effects, and a
dependence of the relationships on the trophic level of the species. By
comparing our results to simple neutral models found in the literature, we
identify the features that are responsible for the values of the exponents.Comment: Theor Ecol (2019
POLICY IMPLICATIONS ON THE REDUCTION OF NITROGEN FERTILIZER USE ON NON-IRRIGATED CORN-WINTER WHEAT PRODUCTION IN NORTH ALABAMA
Environmental and economic effects of nitrogen fertilizer reduction on North Alabama small farms are evaluated using GPFARM. GPFARM incorporates climate, soil data and management practices to simulate science and economic analysis for a farm/ranch management unit. Nitrate leaching, crop yield and profitability are evaluated and presented under different policy scenarios. Key words: nitrate leaching, profitability, management unit, GPFARMnitrate leaching, profitability, management unit, GPFARM, Crop Production/Industries,
