Business Formation and Aggregate Investment

GERMAN ECONOMIC REVIEW, Issue 1 2001
Christian Keuschnigg
The paper proposes an intertemporal equilibrium model of vintage capital and monopolistic competition. Reflecting a tradeoff between the number and capacity of new machines, investment may be extensive or intensive. External gains from specialization and rationalization result in distorted investment decisions. The paper compares the effectiveness of a general investment tax credit with a start-up subsidy that shifts the direction of investment towards a more extensive form. An optimal policy of investment promotion is derived. [source]

A recombined haplotype in the major histocompatibility region contains a cluster of genes conferring high susceptibility to ulcerative colitis in the Spanish population

INFLAMMATORY BOWEL DISEASES, Issue 9 2005
Laura Fernández PhD
Abstract Background: The most consistently described associations in ulcerative colitis (UC) have been with human leukocyte antigen (HLA) class II alleles. Our aim was to look for associations among distinct genetic polymorphisms in the major histocompatibility complex (MHC) that might play a role in determining the susceptibility to UC and especially to the extensive form of the disease. Methods: A case-control study was performed with a total of 253 patients with UC and 315 healthy controls recruited from a single Spanish center. All the samples and 4 cell lines carrying DRB1*0103 or DRB1*1501 alleles were typed for the HLA-DRB1 class II gene and for a panel of HLA class III markers (D6S273, BAT_2, TNFa, b, c, d, e, IKBL+738, MICA). Results: The frequency of the alleles DRB1*0103, IKBL+738(C) (extending our previous results) and BAT_2-8 (newly typed) was increased in patients compared with controls (P = 0.00001, odds ratio [OR] = 5.90; P = 0.002, OR = 2.42; and P = 0.0001, OR = 3.04, respectively), and these associations were greatest in patients with extensive disease compared with patients with distal disease (P = 0.02, OR = 2.53; P = 0.002, OR = 3.06; and P = 0.03, OR = 2.08, respectively). The allelic combination DRB1*0103/D6S273-5/BAT_2-8/TNFa11b4c1d3e3/IKBL+738(C)/MICA5.1 that includes the telomeric class III markers of the 7.1 ancestral haplotype is highly increased in patients with UC (P = 0.0001, OR = 10.57), especially in those with the extensive form of the disease (P = 0.02, OR = 3.41 extensive versus distal). Conclusions: The above-mentioned pattern, most likely formed by recombination of the telomeric fragment of the MHC 7.1 ancestral haplotype, seems to be the most important genetic determinant of susceptibility to the extensive form of UC in our population.

Effects of machinery-sharing arrangements on farm efficiency: evidence from Sweden

AGRICULTURAL ECONOMICS, Issue 5 2010
Karin Larsén
Machinery-sharing; Partnerships; Data envelopment analysis Abstract The effects of partnerships, in the form of machinery-sharing arrangements, on farm efficiency are analyzed using data for Swedish crop and livestock farms. Efficiency scores are obtained using Data Envelopment Analysis and the findings suggest that efficiency is, on average, higher among partnership farms compared to nonpartnership farms. Moreover, partnership farms that are characterized by the most extensive form of collaboration, that is, that share all machinery with one or several other farms, display the highest average efficiency. In a two-stage procedure in which efficiency determinants are analyzed in the second stage, the bootstrap procedures suggested by Simar and Wilson (2007) are applied in addition to the conventionally used Tobit regression. Participation in partnership arrangements is found to have a positive and statistically significant impact on farm efficiency. [source]

The Good, the Bad and the Ugly: The Media in Prison Films

THE HOWARD JOURNAL OF CRIMINAL JUSTICE, Issue 2 2006
JAMIE BENNETT
In particular prison films are an important and extensive form of media depiction. However, media depiction of crime and imprisonment has been criticised on ethical, political and social grounds. This article explores how prison films have depicted the relationship between the media, crime and punishment. It argues that this is a significant and integrated part of the prison film genre. It also argues that these representations are important both as a narrative device and in making the media a focus of pressure for reform. [source]

Mobile technology in the village: ICTs, culture, and social logistics in India

THE JOURNAL OF THE ROYAL ANTHROPOLOGICAL INSTITUTE, Issue 3 2008
Sirpa Tenhunen
Mobile technology is currently emerging as the first extensive form of electronic communication system in many regions of Africa and Asia. This article analyses the appropriation of mobile phones in rural India by exploring what new social alternatives mobile phones enable and how these new social constellations relate to culture and cultural change. The ethnographic description relates phone usage to other communication patterns and ongoing processes of transformation. The article shows how the appropriation of phones draws from the local cultural and social context, but also that phones facilitate new patterns that show great similarity with social processes in other places where phones have been introduced as the first form of communication technology, such as the increased multiplicity of social contacts and the greater efficiency of market relationships. I argue that mobile technology amplifies ongoing processes of cultural change but does so selectively, so that it brings about the homogenization of ,social logistics'. Résumé Dans de nombreuses régions d'Asie et d'Afrique, la technologie mobile apparaît aujourd'hui comme la première forme étendue de communications électroniques. L'auteur analyse ici l'appropriation de la téléphonie mobile en Inde, en explorant les nouvelles alternatives sociales que le téléphone portable rend possibles et les liens entre ces nouvelles constellations sociales, d'une part, et d'autre part la culture et le changement culturel. La description ethnographique fait le lien entre l'utilisation du téléphone et les autres modes de communication et avec les processus actuels de transformation. L'article montre comment l'appropriation du téléphone s'inscrit dans le contexte culturel et social local, tout en mettant en lumière la similarité entre la façon dont le téléphone facilite de nouveaux schémas de communication et les processus sociaux qui se déploient dans d'autres lieux où la téléphonie a été introduite comme première forme de technologie de communication : multiplication des contacts sociaux, efficacité accrue des relations de marché. L'auteur affirme que la technologie mobile amplifie les processus actuels de changement culturel, mais quelle le fait de manière sélective, en induisant ainsi une homogénéisation de la « logistique sociale ».
