Measuring Outcome and Impact of Small Development Projects: Lessons from the Evaluation of a Training Project on Low External Input Agriculture in Guatemala
Impact studies at the level of the beneficiary are not very common in the case of small-scale development projects. In this paper we will present the case of an evaluation study on a training project in Low External Input Agriculture in Guatemala. The evaluation design is based on a simple quasiexperimental design and complemented by qualitative methods of data collection. We want to illustrate that the type of mixed method evaluation used in the case can constitute a useful alternative to study the outcome and impact of small-scale development interventions given their specific constraints of money, expertise and time.
Synthesis and viscosity behavior of poly(γ-p-biphenylmethyl-L-glutamate) in benzene/dichloroacetic acid mixtures, a comparison with poly(γ-benzyl-L-glutamate)
The synthesis of poly(γ-p-biphenylmethyl-L-glutamate), PBPLG, (poly{L-imino-1-[2-(4-biphenylylmethoxycarbonyl)ethyl]-2-oxoethylene}), (1d) is described. The viscosity behavior of this polymer in benzene/dichloroacetic acid mixtures (c=0,2.10 -3 - 1,4.10 -3 g/cm3) at 25°CC is investigated. The results are compared with measurements on poly(γ-benzyl-L-glutamate), PBLG, (poly[L-imino-1-(2-benzyloxycarbonylethyl)-2-oxoethylene]), (1c) under the same conditions. A transition from a rigid hydrogen bonded helix to a random solvated coil occurs in two stages for both: PBPLG (first stage 0-55%, second stage 55-100% dichloroacetic acid) and PBLG (first stage 0-70%, second stage 70-100% dichloroacetic acid). \ud
Therefore, the introduction of a p-phenyl substituent in PBLG leads to a less stable helix in benzene/dichloroacetic acid mixtures. \ud
The stability and viscosity behavior of PBLG in benzene/dichloroacetic acid mixtures (c=0,2.10 - 3 - 1,4.10 - 3g/cm3) is quite similar to the behavior of PBLG in m-cresol/dichloroacetic acid mixtures (c=1,0.10 - 3 - 4,0.10 - 3 g/cm3)
Determinants of regional productivity growth in Europe: an empirical analysis
Discussion on the possibilities for and barriers to income convergence and catch-up growth is at the heart of the debate on European regional economic policy. This study presents an empirical analysis of the determinants of regional productivity growth in Europe, using the most recent Cambridge Econometrics regional database, EU KLEMS growth and productivity accounts and EuroStat R&D data. We apply a reduced-form empirical specification for semi-endogenous productivity growth that allows for differences in steady state income levels and long-run growth rates. Productivity growth in a region depends on its level of human capital, the investments in R&D, and the productivity gap with the technology frontier. Empirical findings show that these factors are interrelated. Apart from a technology gap, absorptive capacity is important to realize catch-up. Both convergence and divergence of productivity across regions are possible. Results show that all considered factors have significant effect on disparity in regional productivity growth, although effects across manufacturing and service sectors are different. The estimated model also features stable dynamic properties in response to an exogenous shock. Keywords: Semi-endogenous Growth, Regional Convergence, International Transfer of Technology, human capital, R&D.
Quantified Self: Groningen zet stappen
Of het nu gaat om het kwantitatief in kaart brengen van het beweeggedrag van een groep kinderen, het overbrengen van kennis over lichaamsbeweging of het creëren van bewustwording over gezond beweeggedrag, er liggen tal van kansen om met nieuwe technologie het vak bewegingsonderwijs te verrijken. In dit artikel is beschreven op welke wijze het project 'Groningen zet stappen' dit in de praktijk heeft toegepast
Cultural distance, institutional distance and international trade
There is large variation in trade patterns across the world. Despite the popular discussion on the ‘death of distance’, distance is still the most important variable explaining this variation. In explaining trade patterns across the worls, it is important to acknowledge the multiple dimensions of distance. In this paper, we empirically investigate the relevance of several of these dimensions. Apart from physical distance, we also consider the effects of cultural distance and institutional distance. Our results reveal the importance of all three dimensions. JEL classification: F14 Keywords: bilateral trade, gravity models, cultural distance, institutional distanc
Bench-to-bedside review: genetic influences on meningococcal disease
This review discusses the possible involvement of a variety of genetic
polymorphisms on the course of meningococcal disease. It has been shown
that several common genetic polymorphisms can either influence the
susceptibility to meningococcal disease or can account for a higher
mortality rate in patients. Gene polymorphisms concerning antibody
receptors, lipopolysaccharide (LPS) binding receptors or proteins, innate
complement proteins as well as cytokines and hemostatic proteins are
described. The study of genetic polymorphisms might provide important
insights in the pathogenesis of meningococcal disease and could make it
possible to identify individuals who are at risk of either contracting or
dying from meningococcal disease
