This paper studies the effects of different types of research policy on economic growth. We find that while tax incentives to private research, public funding of private projects, and basic research performed at public institutions have unambiguously positive effects on economic growth, performing applied research at public institutions could have negative growth effects. This is due to the large crowding out of private research caused by public R\&D when it competes with private firms in the "patent race". Concerning the effects of these policies on welfare, it is found that research policy can either improve or reduce consumer welfare depending on the characteristics of the policy and that an excessively high research subsidy will reduce it.

Research carried out in Tokyo Institute of Technology. The objective is to determine the influence of Interfacial Transition Zone (ITZ) around Lightweight aggregate in concrete on Chloride ion diffusivity. The ITZ of conventional concretes is the weakest point of concrete. The accumulating water on ITZ zone forms the most permeable area inside the concrete. Hence ITZ paves the way for chloride ion diffusion. The quality of ITZ depends on type and quality of aggregates used, water-cement ratio and also the method used for the production of concrete. It has been used two types of lightweight aggregates will be used, Chinese and Japanese, with different absorption capacities. The idea is to produce concrete with same effective water - cement ratio, using the same aggregates in two different conditions, dry and saturated, and compare the chloride ion diffusivity in these concretes (by diffusion test). A comparison of ITZ thickness of these concretes by SEM and EDAX-maps is also proposed. The chloride ion diffusion of concretes produced with the same effective water – cement ratio and same aggregates (dry and ssd) will depend, mainly, on ITZ.

Purpose - This paper focuses on analyzing the effect that public reforms have on the efficiency of state-owned enterprises in regulated environments. Design/methodology/approach - The research is focused in the postal sector where public and private companies must obey a legal framework related to provide a universal service. The analysis is carried out using a panel of 7 European postal operators for the period 1997-2003. The activity analyzed was the letter mail division; we take as key variable the unit cost of a letter and use a translog cost function where as independent variables we include traffic levels, labor cost per employee, quality and availability of the service as well as the type of ownership (public or private). Additionally, in a second stage the geographical differences among countries are considered. Findings - Results indicate that postal operators that experienced organizational changes without being privatized, such as the Spanish and Greek operators, do not have higher unit costs than privatized postal operators like the one of Germany and the Netherlands. Moreover, we find that in all cases the operator of Ireland appear to be the most efficient. In this case restructuring process has been carried out giving an important leadership role to workers. This suggests us that labor culture could be a key variable to study when analyzing reform processes in public enterprises. Originality/value - Our findings show that in a regulated environment like in the postal sector, public and private companies can obtain similar efficiency levels in term of unit costs.

This paper investigates the effects of monetary rewards on the pattern of research. We build a simple repeated model of a researcher capable to obtain innovative ideas. We analyse how the legal environment affects the allocation of researcher's time between research and development. Although technology transfer objectives reduce the time spent in research, they might also induce researchers to conduct research that is more basic in nature, contrary to what the skewing problem would presage. We also show that our results hold even if development delays publication.

Estudio elaborado a partir de una estancia en el Institut fur Vogelforschung. El objeto de la estancia fue participar en la campaña de campo en la colonia de Charrán común (Sterna hirundo) situada en Wilhelmshaven (Alemania), entre los meses de mayo y agosto de 2005. Esta participación se llevó a cabo bajo la dirección del Prof. Dr. Peter H. Becker y junto a su equipo. Se participó en la recogida rutinaria de datos de la colonia así como en distintas técnicas relacionadas con el presente proyecto, como el marcaje de pollos, su observación directa desde escondites y la recogida de distintas muestras biológicas. El objetivo principal era continuar con la obtención de datos para el trabajo de investigación sobre la influencia de la calidad y la condición parental en la manipulación adaptativa de la razón de sexos y la asignación por sexos. La obtención de datos se basa en la implantación de transponders en pollos, que permiten la identificación de cada charrán de por vida. La combinación de esta información con la observación directa de cebas hace de la colonia un lugar excepcional, lo que permite conocer los factores que influyen en las tendencias que existan. Sin embargo, el objetivo específico de la campaña se centraba en investigar la variabilidad individual de la respuesta inmune en los pollos de charrán en relación a un número de atributos de los propios pollos (sexo, tamaño, tasa de crecimiento, proteínas en plasma, hematocrito, carga parasitaria, carotenos en plasma, isótopos de las plumas), de los padres (fecha y tamaño de puesta, calidad parental) y de las condiciones de cría (orden de eclosión, densidad de la sub-colonia). Los resultados de estos datos obtenidos durante la campaña respaldan que existe una influencia de la condición nutricional y la calidad parental en la respuesta immune de los pollos, debida probablemente a un esfuerzo reproductivo diferencial.

This paper is a positive analysis of the driving forces in interdisciplinary research. I take the perspective of a research institution that has to decide how to apply its resources among the production of two types of knowledge: specialized or interdisciplinary. Using a prize mechanism of compensation, I show that the choice of interdisciplinarity is compatible with profit maximization when the requirement for the production is sufficiently demanding, and when the new interdisciplinary field is not too neutral. Productive gains due to complementarities of efforts is the main advantage of interdisciplinary organization.

I analyze, in the context of business and science research collaboration, how the characteristics of partnership agreements are the result of an optimal contract between partners. The final outcome depends on the structure governing the partnership, and on the informational problems towards the efforts involved. The positive effect that the effort of each party has on the success of the other party, makes collaboration a preferred solution. Divergence in research goals may, however, create conflicts between partners. This paper shows how two different structures of partnership governance (a centralized, and a decentralized ones) may optimally use the type of project to motivate the supply of non-contractible efforts. Decentralized structure, however, always choose a project closer to its own preferences. Incentives may also come from monetary transfers, either from partners sharing each other benefits, or from public funds. I derive conditions under which public interventio

In order to complete the study of the very rich early Tithonian (Hybonoticeras hybonotum Zone) radiolarian fauna from the Muhlheim Member of the Mornsheim Formation outcropping in the Solnhofen area, the taxa of the family Saturnalidae are described. Although rather rare, the Saturnalidae of this member contain 14 species, ten of which are new. These species belong to four genera, one of which is new (Moebicircus n. gen.), and two subfamilies (Hexasaturnalinae and Saturnalinae). The taxonomy at generic level of these late Jurassic radiolarians is founded on the basis of the position of the blades along the ring and number and morphology of the spines. Type of spines (simple or forked) has either species level value or none, depending on species. Special attention was given to anomalies, which sometimes are rather frequent, since they can give information of paleobiological and paleoecological orders. Among them frequent cases of open ring and additional spines with Dicerosaturnalis and Siamese twins skeletons with Spongosaturninus and Dicerosaturnalis are to be noted. The authors hope that this new taxonomy will give a better image of the evolution and radiation of the Saturnalidae during the Tithonian.

BACKGROUND: The feasibility of clinical trials depends, among other factors, on the number of eligible patients, the recruitment process, and the readiness of patients to participate in research. Seeking patients' views about their experience in research projects may allow investigators to develop more effective recruitment and retention strategies. METHODS: A total of 100 patients consecutively admitted to a psychiatric university hospital were interviewed with respect to their willingness to participate in a study. For a different study scenario, patients were asked whether they would be ready to participate if such a study were organized in the service and to indicate their reasons for refusing or for participating. RESULTS: The general readiness to participate in a study ranged between 70% and 96%. The prospect of remuneration did not notably augment the potential consent rate. The most common and spontaneous motivation for agreeing to take part in a study was to help science progress and to allow future patients to benefit from improved diagnosis and treatment (87%). The presence or lack of a financial incentive was rarely chosen as an argument to agree (23%) or to refuse (7%) to participate. Patients relied mainly on their treating physicians when contemplating possible participation in a study (family physician [65%] and hospital physician [54%]). CONCLUSIONS: Clinicians and, in particular, treating doctors can play an important role in facilitating the recruitment process.
