Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

Equality of Opportunity and Optimal Cash and In-Kind Policies
No full textThis paper examines the argument for public provision of certain private goods, like education and health, based on equality of opportunity by studying the utility possibility frontier of a society in which there is a concern for the distribution of these goods. A given quality of education or health services can be consumed for free in the public sector, but people can opt-out and purchase their desired quality levels in the private sector. Some of the conclusions are: (i) a pure cash transfer is optimal when the utility redistribution is either “sufficiently” small or large; (ii) if and only if both the equality-of-opportunity concern and the utility redistribution are large enough, can an in-kind program which attracts the whole population be justified; (iii) even when everybody chooses the in-kind program, it may be optimal to perform some additional utility redistribution by increasing the size of such program.equality of opportunity, redistribution, education, in-kind
Present-Biased Individuals, Optimal Paternalism, and Transfers in Kind
No full textPresent-biased preferences cause distortions in consumption that can motivate the use of paternalistic in-kind transfers. Empirically, goods are consumed to different degrees when consumption outlay changes. Economists distinguish between necessary goods and luxury goods. A present-biased individual has an intertemporal distortion of consumption toward the present, which in turn distorts present consumption toward luxury goods. In-kind transfers of necessary goods, such as food stamps, can alleviate the intertemporal distortion and make present-biased transfer recipients better off. Further, transfers in kind are asymmetrical in the sense that they can target present-biased recipients without affecting fully rational recipients.in-kind transfers; time preference
Forced Manager Turnovers in English Soccer Leagues: A Long-Term Perspective
No full textThe authors conduct an empirical analysis of a hand-collected sample of 2,376 turnovers of soccer managers in the four major English leagues in the seasons from 1949-1950 to 2007-2008. While the relation between the probability of a manager being fired and long-term performance remained remarkably stable, both the absolute frequency and the sensitivity of firing decisions on the outcome of recent matches steadily and significantly increased during the six decades covered by the sample. This is likely to reflect the increased level of competition in and economic importance of the English soccer leagues. © The Author(s) 2012
Pareto improvements by in-kind-transfers
No full textThis paper shows that in-kind-transfers are an effective instrument to stabilize agreements when compliance cannot be guaranteed. It demonstrates the weak superiority of in-kind-transfers for a unilateral relationship between two agents. In particular, it proves that, under conditions of perfect knowledge and necessary selfenforcement of contracts, both agents are at least not worse off by in-kind-transfers compared to monetary payments when no selfenforcing contract exists which,is based on monetary payments. This result holds for finitely and for infinitely repeated games.
The GEOFON Program
No full textFollowing the long tradition in broadband seismology in Germany, the GedForschungsZentrum (GFZ) at Potsdam, an institution for interdisciplinary research in geosciences, founded in 1992 by the Federal Ministry of Research and Technology, has started a program for the establishment of a network of globally distributed broadband seismic stations. The program, called GEOFON (GEOFOrschungsNetz), is dedicated to Emst von Rebeur-Paschwitz who recorded the first teleseismic seismogram, 1889 in Potsdam and proposed a global seismograph network and an earthquake reporting system. Our program will, after its completion, consist of three parts: a permanent network of about 30 stations, a portable broadband network and a comprehensive data archive. It is planned for two three-year periods (1993-1995 and 1996-1998). The funding for the first period has already been provided almost completely. An Advisory Board with members from German Universities and the GFZ guides the operation of GEOFON. The main task of the program is to serve the seismological community with high quality broadband data for all kinds, of scientific tasks. The research projects at the GFZ itself, to be carried out with GEOFON and other broadband data, are presently dealing mainly with lithospheric and upper and lower mantle 3D structure

The Impacts of Cash and In-Kind Transfers on Consumption and Labor Supply: Experimental Evidence from Rural Mexico
No full textThe authors use the unique experimental design of the Food Support Program (Programa Apoyo Alimentario) to analyze in-kind and cash transfers in the poor rural areas of southern states of Mexico. They compare the impacts of monthly in-kind and cash transfers of equivalent value (mean share 11.5 percent of pre-program consumption) on household welfare as measured by food and total consumption, adult labor supply, and poverty. The results show that approximately two years later the transfer has a large and positive impact on total and food consumption. There are no differences in the size of the effect of transfer in cash versus transfers in-kind on consumption. The transfer, irrespective of type, does not affect overall participation in labor market activities but induces beneficiary households to switch their labor allocation from agricultural to nonagricultural activities. The analysis finds that the program leads to a significant reduction in poverty. Overall, the findings suggest that the Food Support Program intervention is able to relax the binding liquidity constraints faced by poor agricultural households, and thus increases both equity and efficiency.Adult Work Incentives; Cash Transfers; Consumption; Difference-in-Differences; In-Kind Transfers; Mexico; Poverty Measures; PAL; Randomized design.
Which Kind of Science Is Construction Management?
No full textIt is argued that the mainstream views on the nature of construction management are insufficient, and as one consequence of this, the relevance of construction management has been questioned. As a solution to this situation, construction management is suggested to be repositioned as a design science, rather than as an explanatory science. A historical consideration reveals that design science equals to one of the sciences proposed by Aristotle, however, the suggestion of Aristotle has been forgotten. Thus, there has been a long-standing neglect of the design science, which explains the present fragmentation of this field. It is argued that this redefinition of construction management will solve several problems plaguing this discipline, including the problem of relevance
