South Broadway: A Qualitative Analysis of Legal Marijuana and Place in a Denver Commercial District
The economic impact of legalized marijuana has been massive, but does legal marijuana have the impact to create new types of urban spaces? The legalization of formerly illicit vices has created urban spaces thematically constructed around vice, such as The Strip in Las Vegas (gambling) or The Wallen in Amsterdam (prostitution). This paper suggests that legalized marijuana similarly has the potential to construct vice-themed urban spaces in a post-industrial economic paradigm defined by consumption. Using Denver’s South Broadway (an urban area that has been rebranded as “The Green Mile” due to the outgrowth of marijuana businesses in the area) as the foundation for the analysis, this paper uses qualitative methodologies including historical and content analysis and interviews to examine how marijuana becomes normalized through legalization and resituated for mass consumption, in turn creating the possibility for the construction of thematic urban spaces
Supplemental health insurance and equality of access in Belgium.
It has been suggested that the unequal coverage of different socio-economic groups by supplemental insurance could be a partial explanation for the inequality in access to health care in many countries. We analyse the situation in Belgium, a country with a very broad coverage in compulsory social health insurance and where supplemental insurance mainly refers to extra-billing in hospitals. We find that this institutional background is crucial for the explanation of the effects of supplemental insurance. We find no evidence of adverse selection in the coverage of supplemental health insurance, but strong effects of socio-economic background. A count model for hospital care shows that supplemental insurance has no significant effect on the number of spells, but a negative effect on the number of nights. This is in line with patterns of socio-economic stratification that have been well documented for Belgium. It is also in line with the regulation on extra-billing protecting patients in common rooms. For ambulatory care, we find a positive effect of supplemental insurance on visits to a dentist and on number of spells at a day centre but no effect on visits to a GP, on drugs consumption and on visits to a specialist.Costs; Cost; Risk; Policy; Choice; Insurance; Equality; Belgium;
Port Pricing. Considerations on Economic Principles and Marginal Costs
Pricing by ports and operators within ports is considered quite a complex and untransparant matter, and as such it is sometimes perceived as archaic. This often results in debates about subsidies, captive markets and the dredging and deepening of maritime access routes, raising questions concerning potential distortion of competition and/or abuse of monopolistic power. This paper starts from the most important scientific literature on port pricing (and port competition), and adds new empirical results while calculating the marginal cost of a port call. A distinction is made between four elements of marginal costs in port operations, being costs for provision of infrastructure, costs associated with the use of the transport mode, costs for supplying port services, and external costs. This material may constitute the basis for a meaningful debate on the implementation of a pricing approach that is grounded on the marginal cost principle
Stimulating job crafting behaviors of older workers:The influence of opportunity-enhancing human resource practices and psychological empowerment
Since job crafting behaviour is of profound importance for the retention of older workers, we examined how organizations can stimulate job crafting behaviour among older workers with opportunity-enhancing Human Resource (HR) practices. We introduced three job crafting behaviours: accommodative, utilization, and developmental job crafting. We hypothesized that opportunity-enhancing HR practices increase psychological empowerment among older workers and therefore their job crafting behaviour. We conducted a survey study with two waves among 125 Dutch older workers (65+) affiliated with a temporary employment agency aiming to employ older workers and found that changes in perceptions of opportunity-enhancing HR practices are positively related to changes in psychological empowerment and, in turn, to changes in utilization and developmental crafting behaviours. Unexpectedly, changes in psychological empowerment were not associated with changes in accommodative crafting and changes in opportunity-enhancing HR practices perceptions were not directly associated with changes in job crafting behaviour. With this study, we contribute to the literature on job crafting and human resource management by showing that opportunity-enhancing HR practices influence job crafting behaviour through psychological empowerment
A GIS-based multi-criteria analysis on cropland suitability in Bornuur Soum, Mongolia
Agriculture is one of the most critical sectors of the Mongolian economy. In Mongolia, land degradation is increasing in the cropland region, especially in a cultivated area. The country has challenges to identify new croplands with sufficient capacity for cultivation, especially for local decision-makers. GIS applications tremendously help science in making land assessments. This study was carried out in Bornuur soum, Mongolia. The goal of this study to estimate that best suitable area for supporting crop production in Bornuur soum, using a GIS-based multi-criteria analysis (MCA) and remote sensing. GIS-based multi-criteria analysis (MCA) has been widely used in land suitability analyses in many countries. In this research, the GIS-based spatial MCA among the Analytical Hierarchy Process (AHP) method has employed. The approach was enhanced for each criterion which as soil, topography and vegetation. The opinions of agronomist experts and a literature review helped in identifying criteria (soil data, topography, water and vegetation data) that are necessary to determine areas suitable for crops. The detailed cropland suitability maps indicate that 46.12 % is highly suitable for cropland, 34.68 % is moderate suitable, 13.64 % is marginal suitable and 5.56 % is not suitable. The MCA and AHP tools play an essential role in the multi-criteria analysis. Therefore, the results of these methods allow us to estimate an appropriate area for cultivation in Bornuur soum, Tuv province. The crop suitability method implies significant decisions on different levels and the result will be used for cropland management plan to make a decision. It is an integral role in agricultural management and land evaluation. Future research should further develop this method by including socio-economic (potential citizens for agriculture, current crop growth, water resource, etc.) and environmental variables (rainfall, vegetation types, permafrost distribution, etc.) to obtain specific results. However, it could be also be applied for a single crop type (mainly barley, wheat and potato) in Mongolia
Soil biochar amendment in a nature restoration area: effects on plant productivity and community composition
Abstract. Biochar (pyrolyzed biomass) amendment to soils has been shown to have a multitude of positive effects, e.g., on crop yield, soil quality, nutrient cycling, and carbon sequestration. So far the majority of studies have focused on agricultural systems, typically with relatively low species diversity and annual cropping schemes. How biochar amendment affects plant communities in more complex and diverse ecosystems that can evolve over time is largely unknown. We investigated such effects in a field experiment at a Dutch nature restoration area. In April 2011, we set up an experiment using biochar produced from cuttings collected from a local natural grassland. The material was pyrolyzed at 4008C or at 6008C. After biochar or residue (non-pyrolyzed cuttings) application (10 Mg/ha), all plots, including control (0 Mg/ ha) plots, were sown with an 18-species grassland mixture. In August 2011, we determined characteristics of the developed plant community, as well as soil nutrient status. Biochar amendment did not alter total plant productivity, but it had a strong and significant effect on plant community composition. Legumes were three times as abundant and individual legume plants increased four times in biomass in plots that received biochar as compared to the control treatment. Biomass of the most abundant forb (Plantago lanceolata) was not affected by biochar addition. Available phosphorous, potassium, and pH were significantly higher in soils that received biochar than in Control soils. The rate of biological nitrogen fixation and seed germination were not altered by biochar amendment, but the total amount of biological N fixed per Trifolium pratense (red clover) plant was more than four times greater in biochar-amended soil. This study demonstrates that biochar amendment has a strong and rapid effect on plant communities and soil nutrients. Over time these changes may cascade up to other trophic groups, including above-and belowground organisms. Our results emphasize the need for long-term studies that examine not only the short-term effects of biochar amendment, but also follow how these effects evolve over time and affect ecosystem functioning
