More Rights, Less Income? An Economic Analysis of the New Copyright Law in Germany
The German copyright law was reformed in the end of 2016 with the purpose of ensuring reasonable pecuniary compensation to authors. It proposes an option which entitles authors to negotiate copyright transfers with an additional publisher after a vesting period of ten years. The results of a two-stage bargaining model show that the proposed copyright system may actually harm authors, as publishers may internalize a potential impairment on profits from increased competition within contract negotiations. This paper also demonstrates that the publisher's willingness to invest into an author's career is strictly decreasing as the level of expected rivalry increases
Efficient Contracting Under The U.S. Copyright Termination Law
The American copyright act from 1976 allows authors to terminate their copyright grants after a certain vesting period if these are not categorized as work made for hire. The literature suggests substantial effects on the author-publisher relationship because in negotiations publishers may internalize the harm from a termination decision. This paper illuminates the internalization problem and shows that contracts should be designed differently for terminating and non-terminating authors. The total remuneration offered by the initial publisher is strictly lower for authors who terminate. This paper also points out the limits of the copyright law under scrutiny considering additional institutional regulations and existing market norms
Kündigungsschutzrecht in den USA und in Deutschland: ein Beitrag zur ökonomischen Rechtsvergleichung
Der Beitrag plädiert für die Verwendung der ökonomischen Analyse als Methode der Rechtsvergleichung. Mit ihrer Hilfe wird gezeigt, daß das Vorurteil unbegründet ist, der Kündigungsschutz sei in den USA ?schwächer? (arbeitgeberfreundlicher) als in Deutschland. Die erwartete Abfindungszahlung kann in beiden Rechtssystemen durchaus gleich hoch ausfallen (in Deutschland ist die Wahrscheinlichkeit einer Abfindung höher, in den USA die Höhe der Zahlung). Eine institutionenökonomische Analyse zeigt darüber hinaus, daß die Beteiligung des Betriebsrates an Kündigungen in Deutschland opportunistisches Verhalten der Arbeitgeber und Arbeitnehmer einzudämmen hilft. Diese Art der Sicherung spezifischer Investitionen in Humankapital könnte zur Erklärung des empirischen Befundes beitragen, daß in Deutschland die Arbeitsproduktivität i.a. höher ist als in den USA. -- The paper argues in favor of the economic analysis as a method of international comparison of legal systems. It demonstrates that the legal rules governing the termination of employment contracts in the US are not "weaker" than in Germany. Arguing in terms of expected damages, the probability of a payment is higher in Germany, whereas the amount to be paid is higher in the US. An economic analysis of the German "workers' council" shows that this institution helps to prevent opportunistic terminations as well as opportunistic behavior of employees, and therefore protects specific investments into human capital. This may provide an explanation for the empirical observation that, in general, the productivity of labor is higher in Germany than in the US.Arbeitsvertrag,Betriebsrat,Quasirenten,spezifische Investitionen,Humankapital,economic comparison of law,termination of labor contracts,quasirents,human capital,specific investments workers' council

Spatial variation in exhumation rates across Ladakh and the Karakoram: New apatite fission track data from the Eastern Karakoram, NW India
Characterization of low-temperature cooling histories and associated exhumation rates is critical for deciphering the recent evolution of orogenic regions. However, these may vary significantly over relatively short distances within orogens. It is pertinent therefore to constrain cooling histories and hence exhumation rates across major tectonic boundaries. We report the first apatite fission track ages from the Karakoram Fault Zone in the Eastern Karakoram range, which forms part of the western margin of the Tibetan Plateau. Ten samples, from elevations of 3477–4875m, have apatite fission track dates from 3.3 ± 0.3 Ma to 7.4± 1.1Ma. The ages correspond to modeled average erosional exhumation rates of 0.67+ 0.27-0.18mm/yr across the Eastern Karakoram. The results are consistent with a trend northward from the Indus suture zone, across the Ladakh terrane and into the Karakoram, in which tectonic uplift associated with crustal thickening increases toward the north, raising elevation and promoting glaciation and generation of extreme relief. As a result, erosion and exhumation rates increase south to north. Present-day precipitation on the other hand varies little within the study area and on a larger scale decreases southwest to northeast across this portion of the orogen. The Eastern Karakoram results highlight the diverse patterns of exhumation driven by regional variations in tectonic response to collision along the western margin of Tibet
Drosophila Neurotrophins Reveal a Common Mechanism for Nervous System Formation
Neurotrophic interactions occur in Drosophila, but to date, no neurotrophic factor had been found. Neurotrophins are the main vertebrate secreted signalling molecules that link nervous system structure and function: they regulate
neuronal survival, targeting, synaptic plasticity, memory and cognition. We have identified a neurotrophic factor in
flies, Drosophila Neurotrophin (DNT1), structurally related to all known neurotrophins and highly conserved in insects.By investigating with genetics the consequences of removing DNT1 or adding it in excess, we show that DNT1
maintains neuronal survival, as more neurons die in DNT1 mutants and expression of DNT1 rescues naturally occurring
cell death, and it enables targeting by motor neurons. We show that Spa¨ tzle and a further fly neurotrophin superfamily member, DNT2, also have neurotrophic functions in flies. Our findings imply that most likely a neurotrophin was present in the common ancestor of all bilateral organisms, giving rise to invertebrate and vertebrate neurotrophins through gene or whole-genome duplications. This work provides a missing link between aspects of neuronal function in flies and vertebrates, and it opens the opportunity to use Drosophila to investigate further aspects of neurotrophin function and to model related diseases
GI+100: Long Term Preservation of Digital Geographic Information — 16 Fundamental Principles Agreed by National Mapping Agencies and State Archives
This paper states 16 principles for the long term retention and preservation of digital geographic information. The paper is mainly aimed at public sector geographic information providers in Europe (particularly those involved in mapping and cadastre) with the intention of highlighting the significance of fundamental concepts for digital geographic data archiving. Geographic information providers are mainly mapping agencies, but also archives preserving geographic data among a wider range of digital information. A supplementary objective is that the paper may provide useful information for providers of all types of geographic information right around the world. This paper states 16 principles for the long term retention and preservation of digital geographic information. The paper is mainly aimed at public sector geographic information providers in Europe (particularly those involved in mapping and cadastre) with the intention of highlighting the significance of fundamental concepts for digital geographic data archiving. Geographic information providers are mainly mapping agencies, but also archives preserving geographic data among a wider range of digital information. A supplementary objective is that the paper may provide useful information for providers of all types of geographic information right around the world. There are many reasons why people wish to retain access to information, though the main drivers for archiving digital geographic information are meeting legislative requirements, the short and long term exploitation (re-use not only access) of archived data for analyzing social, environmental (e.g. global climate changes) and economic changes over time as well as efficiency savings in managing superseded datasets. This paper sets out the path and describes what needs to be done now to future-proof the investment government agencies around the world have made in creating digital Geographic Data.
Risk factors of visceral leishmaniasis: a case control study in north-western Ethiopia
Background
Visceral leishmaniasis (VL, also called “kala-azar”), is a life threatening neglected tropical infectious disease which mainly affects the poorest of the poor. VL is prevalent in Ethiopia particularly in the northwest of the country. Understanding the risk factors of VL infection helps in its prevention and control. The aim of the present study was to identify the factors associated with VL.
Methods
A case–control study was carried out during the period of January-July 2013 in northwest Ethiopia. Cases and controls were diagnosed using clinical presentation, the rk39 rapid diagnostic test and Direct Agglutination Test (DAT). A total of 283 (84.8% males versus 15.2% females) participants were interviewed. 90 cases and 193 controls were involved, matched by age, sex and geographical location with a ratio of 1:2 (case: controls). Univariate and backward multivariate conditional logistic regression were used to identify risk factors of VL.
Results
Elevated odds of VL was associated with goat ownership (OR = 6.4; 95%: confidence interval [Cl]: 1.5-28.4), living in houses with cracked wall (OR = 6.4; 95% Cl: 1.6-25.6), increased family size (OR = 1.3; 95% Cl: 1.0-1.8) and the number of days spent in the farm field (OR = 1.1; 95% Cl: 1.0-1.2). However, daily individual activities around the home and farm fields, mainly sleeping on a bed (OR = 0.2; 95%: Cl 0.03-0.9), sleeping outside the house under a bed net (OR = 0.1; 95% Cl: 0.02-0.36)] and smoking plant parts in the house during the night time (OR = 0.1; 95% Cl: 0.01-0.6) were associated with decreased odds of being VL case.
Conclusion
Our findings showed that use of bed net and smoke could be helpful for the prevention of VL in the area particularly among individuals who spend most of their time in the farm. VL control effort could be focused on improving housing conditions, such as sealing cracks and crevices inside and outside houses. Further research is warranted to elucidate the role of goats in the transmission of L. donovani, assess the impact of bed nets and the role of the traditional practice of smoking plants
