Exploring local projects for sustainable energy in system transition: local perceptions of success

In the sustainability transitions literature, ‘success’ is conceived as the transition from an unsustainable system to a sustainable one. However, this view hides a more profound complexity in individual projects which can contribute to system transition. This paper focuses instead on local projects as key sites for change. In two case studies of UK sustainable energy projects, success is shown to be characterised by different causative beliefs held by different people about the problems being addressed, which predetermines solutions to those problems; and hence the nature of success. By acknowledging this multiplicity of success, as perceived by ordinary residents and project organisers as well as transition scholars, ‘narratives of success’ can be recognised, enabling future projects to build on success, and continue along the path to transition. This reconceptualisation provides transition scholars with new ways of understanding and effecting transitions; by focusing on the project level, which is useful in contexts with varying commitment to sustainability.     

The New World of Advertising. Compiled by the editors of Advertising Age. Chicago: Crain Books, 1975

Abstract

This study empirically tested the assumption that the more creative alternatives generated, the better the chance of developing the most effective campaign creative strategy. A panel of four professional creative people from a branch of a “top-twenty” advertising agency judged positioning statements generated by four groups of advertising students. Various analyses of the data tended to confirm the assumption.     

Estimating the Aboriginal Population in Early Colonial Australia: The Role of Chickenpox Reconsidered

Noel Butlin radically altered the debate about the pre-colonial Aboriginal population when he provided a set of hypothetical demographic scenarios, which nonetheless were both grounded in economic theory or human ecological considerations and broadly consistent with what we know about the historical record. This research builds on Butlin's legacy by exploring how his scenarios are consistent with both the medical understandings of the infectiousness and mortality of various diseases and the history of settlement. Another contribution from this paper is to highlight the possible role of chickenpox in the Aboriginal depopulation in the early colonial period.     

Globalization and the connection of remote communities: A review of household effects and their biodiversity implications

The remote regions of the world provide refuge to a disproportionate amount of the Earth's biodiversity. As globalization continues, isolated human communities in these regions are increasingly connected to global market, migration, and technology networks. We review the diffuse literature on the household effects of changing market access, migration, and technology adoption in remote regions and implications for native biodiversity. Market access affects biodiversity in remote communities through changes in household economics and social networks. Migration, either to or from remote settlements, affects biodiversity through changes in population, remittances, human capital, and social networks. Finally, we consider effects due to production, public infrastructure, and information and communication technologies. There is much ambiguity surrounding these causal pathways, and thus we also examine the roles of various ecological, household, community, and institutional mediating factors in determining the impacts of global connection. Finally, we explore the limitations of our current knowledge and research practices and propose directions for future work to address key uncertainties in theory and evidence as well as weaknesses in methodological approaches. We recommend a broad and interdisciplinary mode of inquiry as the best means toward clarifying globalization's impacts on human settlements and the biodiversity harbored in the Earth's remaining remote regions.     

Redistributing the energy tax burden in the Philippines

This paper uses an aggregate modelling approach to assess the impacts of a redistribution of the taxes and duties that currently exist on crude oil and refined petroleum products on the Philippine economy. The approach used in the analysis consists of a general equilibrium model composed of fourteen producing sectors, fifteen consuming sectors, three household categories classified by income and a government. The effects of replacing the taxes and duties on crude oil and refined petroleum products with a more broad based tax on manufacturing and service sectors output on prices and quantities are examined. The results are revealing. For example, the consequences of redistributing the tax burden away from petroleum products to the manufacturing and service sectors of the Philippine economy will be an increase in output by all producing sectors of about 3.5 percent or about 2.4 hundred billion Philippine pesos, a rise in the consumption of goods and services by about 6.1 percent or 1.6 hundred billion Philippine pesos, a rise in total utility by 6.9 or 1.9 hundred billion Philippine pesos, and virtually no change in tax revenue for the government. When subjected to a sensitivity analysis, the results are reasonably robust with regard to the assumption of the values of the substitution elasticities. That is, while the model's equilibrium values do vary in response to different assumptions of the values of these elasticities, the fluctuations are not so enormous to suggest that the model is unrealistically sensitive to these parameters.Notation Y _j Total production in sectorj (j=1, 2, ..., 14) - CD _j Consumer demand for productj - GE _j Government endowment of productj - UM _j Imports of productj - _LRAS_jl RAS balanced input-output intermediate demands - GD _j Government demand for productj - INV _j Investment in sectorj - UX _j Exports of productj - SL _c Supply of labor by householdc (c=1, 2, 3) - SK _c Supply of capital by householdc - SD _c Supply of land by householdc - DL _j Demand for labor in the industryj - DK _j Demand for capital in the industryj - DD _j Demand for land in industryj - GDL Government demand for labor - GDD Government demand for land - TL _j Tax on labor in industryj - TK _j Tax on capital in industryj - TD _j Tax on land in industryj - GCE _i Consumer demand for consumer producti (i=1, 2, ..., 15) - Z _ji A 14×15 transformation matrix - RCS _ic RAS balanced matrix of each household's demand for each consumer good - TC _j Excise tax on consumer goodj - TRN _c Transfer payment to householdc - PIT _c Personal income tax payment for householdc - TAU _c Marginal income tax rate for householdc - SAV _c Savings in householdc - GC _c Gross consumption of householdc - ZTA Consumption plus leisure coefficient - TE Total government endowments - EM _j Demand elasticity of export demand - FE _j Endowment/demand sector of adjusted elasticity of export demand - GSK _j Government endowment of capital in industryj - GDK _j Government demand for capital in industryj - GTL Government wage taxes on its own employees - TXO _j Government output tax on industryj - TC _c Consumption taxes on householdc - CG _c Total government consumption by householdc - SAV _c Total savings by householdc - INV _j Total investment by industryj The views expressed are those of the authors and do not necessarily represent the policies of the organizations with which they are affiliated.

Use of the net present value criterion in a random job shop where early shipments are forbidden

Both practitioners and researchers in the field of Operations Management have suggested that shop scheduling should be an integral component in both the strategic and tactical plans for an organization's assets. This paper examines the use of an accepted measure of return on assets, net present value (NPV), in a simulated shop scheduling environment where early shipment of jobs before their due dates is forbidden. In addition, early shipment of raw materials to the shop is also forbidden. This shop environment is consistent with the prevalent practice in industry of accepting orders only on a just-in-time basis to reduce purchased parts inventories. The NPV measure provides a means of balancing a variety of performance criteria that have been treated as separate objectives previously, including work-in-process inventory, finished goods inventory, mean flow time and mean tardiness, while also providing a means of measuring monetarily the value of various shop scheduling approaches.The NPV performance of priority scheduling rules and order release policies is measured in this research through the simulation of a random job shop under a variety of environmental conditions. It is found in a comparison of priority rules that use time-based information with those that use job value information that the Critical Ratio rule provides higher average performance than the three other rules used in the study. However, in some situations that are consistent with JIT practice, value-based priority rules also perform well. The use of a mechanism for delaying the release of jobs to each work center in the shop provided higher average NPV when shop utilization was set at a low level of 80%, while immediate release of work upon its arrival to the shop provided superior performance at a higher shop utilization level of 94%. While JIT materials delivery and costing yields higher NPV, it did not alter the relative ranking of priority rule/release policy combinations. In addition, it was found that environmental factors, including average job length, average number of tasks per job and level of tardiness penalty, resulted in greater variations in NPV performance than the institution of a JIT raw materials delivery policy.
