Beyond recurrent costs: an institutional analysis of the unsustainability of donor-supported reforms in agricultural extension
International donors have spent billions of dollars over the past four decades in developing and/or reforming the agricultural extension service delivery arrangements in developing countries. However, many of these reforms, supported through short-term projects, became unsustainable once aid funding had ceased. The unavailability of recurrent funding has predominantly been highlighted in the literature as the key reason for this undesirable outcome, while little has been written about institutional factors. The purpose of this article is to examine the usefulness of taking an institutional perspective in explaining the unsustainability of donor-supported extension reforms and derive lessons for improvement. Using a framework drawn from the school of institutionalism in a Bangladeshi case study, we have found that a reform becomes unsustainable because of poor demands for extension information and advice; missing, weak, incongruent, and perverse institutional frameworks governing the exchange of extension goods (services); and a lack of institutional learning and change during the reform process. Accordingly, we have argued that strategies for sustainable extension reforms should move beyond financial considerations and include such measures as making extension goods (services) more tangible and monetary in nature, commissioning in-depth studies to learn about local institutions, crafting new institutions and/or reforming the weak and perverse institutions prevailing in developing countries. We emphasize the need to address three categories of institutions â regulative, normative, and cultural-cognitive â and call for an alignment among them. We further argue that, in order to be sustainable, a reform should take a systemic approach in institutional capacity building and, for this to be possible, adopt a long-term program approach, as opposed to a short-term project approach
Cryogenic Propellant Scavenging
A detailed description of a computer model that has been developed for assessing the feasibility of low g cryogen propellant scavenging from the space shuttle External Tank (ET) is given. Either pump-assisted or pressure-induced propellant transfer may be selected. The program will accept a wide range of input variables, including the fuel to be transferred (LOX or LH2), heat leaks, tank temperatures, and piping and equipment specifications. The model has been parametrically analyzed to determine initial design specification for the system

Continuous-wave Raman laser pumped within a semiconductor disk laser cavity
A KGd(WO4)(2) Raman laser was pumped within the cavity of a cw diode-pumped InGaAs semiconductor disk laser (SDL). The Raman laser threshold was reached for 5: 6W of absorbed diode pump power, and output power up to 0.8W at 1143nm, with optical conversion efficiency of 7.5% with respect to the absorbed diode pump power, was demonstrated. Tuning the SDL resulted in tuning of the Raman laser output between 1133 and 1157nm
Bridging the gap between ethnically/culturally diverse \u27others\u27: A contribution to the understanding of how women work together
In this thesis, I explore the ways in which ethnically and culturally diverse women work together to rbedige their differences. Using a critical, feminist, reflexive and post-colonialist approach, I conducted eight in-person, semi-structured interviews with women who were staff and board members, volunteers, or participants in programmes offered by an organization serving immigrant women. Wommen were asked to name their cultural or ethnic identities, to share their views on multiculturalism, tolerance, and the âwelcomingâ of newcomers to Canada, the uniting and divisive issues they faced in their work, as well as appropriate roles for Canadian-born and immigrant women in the organization at which they work. According to my interviews with women and the organizational data, one of the main features of womenâs work together has been their attempt to âfit in.â In the context of this particular organization, âfitting inâ meant that women emphasized commonalities and swerved away from critical and political analyses, particularly around notions of colour, power and privilege. In addition, women within this organization adopted mainstream societyâs âliberalâ view of multiculturalism, which celebrated womenâs diversity, but did not make room for a deeper understanding of the differences between individuals from diverse cultural, ethnic, and racial groups. As such, ethnically and culturally diverse women tended to work together as âCanadians,â and swept aside their differences or challenges. Womenâs responses to the questions regarding the âhowâ of their work together were impacted by their skin colour (visible minority vs. white) and experience with immigration (Canadian-born vs. immigrant to Canada). Colour was a salient predictor of womenâs experiences, as visible minority women (regardless of their country of birth) were more forthcoming about their views on multiculturalism, tolerance, and the roles women should play within the organization. Generally, all participants were quite uncomfortable with critical language around colour, power and privilege, which was understandable given the organizationâs downplaying of âpoliticalâ issues, and our larger societyâs avoidance of issues of power and privilege. To account for some of the âgapsâ in communication between ethnically and culturally diverse women, I discuss the utility of an anti-oppressive framework and the abandonment of critical language (without a rejection of the underlying critical approach) in order to âbuild bridgesâ between diverse women working together in Canada
Perspectives on subnational carbon and climate footprints: A case study of Southampton, UK
Sub-national governments are increasingly interested in local-level climate change management. Carbon- (CO2 and CH4) and climate-footprintsâ(Kyoto Basket GHGs) (effectively single impact category LCA metrics, for global warming potential) provide an opportunity to develop models to facilitate effective mitigation. Three approaches are available for the footprinting of sub-national communities. Territorial-based approaches, which focus on production emissions within the geo-political boundaries, are useful for highlighting local emission sources but do not reflect the transboundary nature of sub-national community infrastructures. Transboundary approaches, which extend territorial footprints through the inclusion of key cross boundary flows of materials and energy, are more representative of community structures and processes but there are concerns regarding comparability between studies. The third option, consumption-based, considers global GHG emissions that result from final consumption (households, governments, and investment). Using a case study of Southampton, UK, this chapter develops the data and methods required for a sub-national territorial, transboundary, and consumption-based carbon and climate footprints. The results and implication of each footprinting perspective are discussed in the context of emerging international standards. The study clearly shows that the carbon footprint (CO2 and CH4 only) offers a low-cost, low-data, universal metric of anthropogenic GHG emission and subsequent management
The optical polarization of Epsilon Aurigae through the 1982-84 eclipse
About 350 nights observations on the 61-cm telescope at Pine Mt. Observatory were made of the variable polarization of Eps. Aurigae during 1982-85, in the U, B, and V color bands. The V data are the most complete and are shown. In terms of the overall features the curves in all three colors are quite similar. The typical errors per nightly point in the V curves are about 0.015% for either of the two normalized, equatorial Stokes parameters Q and U. Note that there is a large background or constant component of some 2.5%, position angle around 135 deg. This is presumably largely interstellar, and the intrinsic polarization probably does not much exceed the amplitude of the variable component, approx. 0.5%. A few field-star polarizations were measured but a very clear pattern was not obtained in this part of the sky
