The O-Ring theory is used to analyze the emergence of ̄rms organized as partnerships. The owner-managers of such entrepreneurial ̄rms bene ̄t from ability matching within their production teams. However, they must bear the project risk. Risk-aversion then induces a second-best solution. Integrated ̄rms managed on behalf of riskneutral residual-claimants face information and/or enforcement problem...

Reducing tax evasion is a key priority for many governments, particularly in developing countries. A growing literature has argued that the use of third party information to verify taxpayer self-reports is critical for tax enforcement and the growth of state capacity. However, there may be limits to the effectiveness of third party information if taxpayers can substitute misreporting to less ve...

In this work, polypropylene (PP) and graphene nanoplatelet (GNPs) composites are routed through twin screw mixing injection moulding. Two types of GNPs with a fixed size 25 µm surface areas ranging from 50–80 m2/g (H25, average thickness 15 nm) 120–150 (M25, 6–8 were blended PP at loading rates 1, 2, 3, 4, 5 weight%. Mechanical properties such as tensile, flexural, impact strengths Young’s modu...

A general perceptual model is proposed for Eldercare Robot implementation that is comprised of audition functionality interconnected with a feedback-driven perceptual reasoning agent. Using multistage signal analysis to feed temporally tiered learning/recognition modules, concurrent access to sound event localization, classification, and context is realized. Patterns leading to the quantificati...

BACKGROUND On 20-21 February 2006, six cases of diarrhoea-associated haemolytic uraemic syndrome (HUS) were reported by paediatricians to the Norwegian Institute of Public Health. We initiated an investigation to identify the etiologic agent and determine the source of the outbreak in order to implement control measures. METHODS A case was defined as a child with diarrhoea-associated HUS or a...

Bu çalışmada, sol-jel spin kaplama yöntemi kullanılarak mikroskop cam altlıklar üzerine TiO2, TiO2/CoPc ve CoPc filmleri hazırlanmış katkı konsantrasyonunun filmlerin optik yapısal özellikleri etkisi araştırılmıştır. İnce geçirgenliğini ölçmek için 300-1100 nm dalgaboyu aralığında bir spektrofotometre kullanılmıştır. Uv-Vis çalışmaları, B Q bandı absorpsiyon bölgelerine karşılık gelen aralıklar...

Economists have speculated for at least a century that the social return to education may exceed the private return. In this paper, I estimate spillovers from college education by comparing wages for otherwise similar individuals who work in cities with di*erent shares of college graduates in the labor force. A key issue in this comparison is the presence of unobservable characteristics of indi...
