The paper would analyze the law and economics of introducing flexibility in the system of exceptions and limitations on European Copyright Law. Such flexibility would exist in an open norm on the basis of which the courts can decide whether certain uses of copyrighted material are permissible or not, instead of explicitly defining this in the law. First, it would assess problem areas where the lack of flexibility creates legal disputes and potential barriers to innovation and commercialization. Second, it would analyze the economic rationale and economic effects of introducing flexibility. Exceptions and limitations in the current copyright system are meant to balance the protection granted to rights owners with the public interest's need to make certain unauthorized uses. However, this paper would identify a number of situations that do not fit well within the current set of exceptions and limitations and attribute this to a lack of flexibility. Several of these problem areas have given rise to court proceedings with varying outcomes. The interpretation given by courts to existing exceptions and limitations---such as the quotation right, the exception for transient and incidental copying, the private copying exception, and the incidental use exception--is usually too narrow to respond to new technological developments, new developments in the creation process, or new commercialization models. These types of uses generally do not fit the narrowly defined exceptions and limitations and therefore lack legal basis. The same is true for things not yet invented. 相似文献

In recent years, there has been a renewed interest in forensic sciences about forensic age estimation in living subjects by means of radiological methods. This research was conducted on digital thorax X-rays to test the usefulness of some radiological changes in the clavicle and first rib. The sample consisted in a total of 123 subjects of Spanish origin (61 men and 62 women; age range: 5-75 years). From all subjects, a thorax posterior-anterior radiograph was obtained in digital format. Scoring for fusion of medial epiphyses of the clavicle was carried out by Schmeling's system and ossification of the costal cartilage of the first rib by Michelson's system. Degree of ossification and epiphyseal fusion were analyzed in relation with known age and sex of these subjects. The results give a minimum age of >20 years for full fusion of the medial epiphysis of the clavicle (Stages 4 and 5). Concerning the first rib, all subjects with the final Stage 3 of ossification were above 25 years of age. These results suggest that the first rib ossification might become an additional method to the ones so far recommended for forensic age estimation in subjects around 21. New research would be desirable to confirm this suggestion. 相似文献

Spectral analysis and ARMA models have been the most common weapons of choice for the detection of cycles in political time series. Controversies about cycles, however, tend to revolve around an issue that both techniques are badly equipped to address: the possibility of irregular cycles without fixed periodicity throughout the entire time series. This has led to two main consequences. On the one hand, proponents of cyclical theories have often dismissed established statistical techniques. On the other hand, proponents of established techniques have dismissed the possibility of cycles without fixed periodicity. Wavelets allow the detection of transient and coexisting cycles and structural breaks in periodicity. In this article, we present the tools of wavelet analysis and apply them to the study of two lingering puzzles in the political science literature: the existence of cycles in election returns in the United States and in the severity of major power wars. 相似文献

Anthropologists and forensic pathologist determine the sex of skeletons by analyzing quantitative and qualitative characters in the bone remains. Generally, the skull and os coxae are the elements most used, but they are not always preserved. In such cases, the investigator needs to have available other techniques based on different remains. The aim of the present work is to develop and describe discriminating functions for sex determination in a recent Spanish population using metacarpal morphology. A sample of bones corresponding to a contemporary Spanish population deposited at the Complutense University of Madrid (UCM) was analyzed. This sample comprised 697 metacarpals, corresponding to 79 adult individuals (37 men and 42 women). These allowed us to obtain 120 unifactorial discriminant functions. We selected the 10 equations, one for each metacarpal from both hands, that provided the best sexual discrimination. The correct sex classification rank progressed from 81%, for right (R) metacarpals IV and V, to 91%, for left (L) metacarpal II. The results suggest that metacarpals are structures that can be used for sex determination in paleoanthropological and forensic identifications. 相似文献

The use of bone as a biomarker for chronic and acute exposure to fluoride salts has been suggested, but there are no data published about its use to evaluate lethal intoxication. One hundred and sixty rats were divided into eight groups that received a single oral intubation dose from 0 (control) to 90 mg F/kg as NaF. The animals' time of death was recorded and their femurs were removed for fluoride analysis. Acid-soluble fluoride was determined in the whole bone and on the surface (periosteal), using an ion specific electrode. The data showed a statistically significant relationship between fluoride dose and the number of deaths (P<0.0001). A statistically significant relationship was also found between fluoride dose and fluoride concentration ([F]) in either the whole femur (P<0.0017), on the surface (P<0.0001) or for the ratio periosteal [F]/whole [F] (P<0.0001). However, the [F] on the femur surface was more closely correlated with mortality than that in the whole bone, showing statistically significant differences among the lethal doses and control (P<0.05). The data suggest that the ratio [F] periosteal bone/[F] whole bone, is a biomarker for acute fluoride toxicity. 相似文献

Argentina has benefited greatly from the increase in prices of agricultural commodities. With a large share of its population with low and medium-low incomes; however, a sizable part of households is likely to be adversely affected by the accompanying rise in the price of the consumption basket. An ex-ante analysis suggests that this is the case. Changes through a less obvious channel (that is, in factor incomes) are likely to be more beneficial to middle-income households. In general, all households experience losses, with poorer households being the most affected. When accounting for transfers financed through the collection of export taxes, poorer households benefit. In the absence of compensatory measures, increases in the prices of agricultural commodities could potentially have an important impact in terms of indigence and poverty. 相似文献
