The purpose of this study is to clarify the chronology of different stages of dental development, according to Demirjian, in a sample of Spanish children, which will enable us to build a database that will be used as a reference in regard to the dental development of individuals of our socio-geographic environment. In the same studied sample, a calculation of the dental age according to Demirjian was carried out. This study was conducted in a final sample consisting of 1010 orthopantograms, corresponding to Spanish children (485 boys and 525 girls) ages 2-16. Comparing the age of onset of the different stages among the children, evidence was found that girls had an earlier general development than boys. These differences were only statistically significant in teeth and concrete stages. The canine teeth revealed greater gender dimorphism, with significant differences in all stages compared with the upper canines. The method proposed by Demirjian for dental age calculation resulted in a significant overestimation of dental age in relation to the chronological age in boys (average of 0.87 years) and girls (average of 0.55 years). Data from this study may be used as reference for dental maturity, as well as a standard for estimating age in Spanish children. 相似文献

One crucial element for the evolution of cooperation may be the sensitivity to others?? efforts and pay-offs in comparison with one??s own costs and gains. If an individual responds to a disadvantageous reward distribution, then it would likely increase its relative fitness compared with those who do not (Brosnan & de Waal, Nature 428:140, 2004). Recent experimental research indicates that sensitivity toward unequal reward distribution is not a uniquely human trait; non-human primates react to inequity if they witness a conspecific that obtains a more attractive reward for the same effort. However, primates are not the only species that cooperate and thus would benefit from inequity aversion. Canids also frequently cooperate with group members (e.g., wolves, wild dogs, etc.) or humans (domestic dogs), allowing for the possibility that they also are sensitive to the reward distribution. We report the findings of two studies of dogs?? responses to inequity and the social factors that mediate such responses. In the first study, we investigated whether domestic dogs showed a response to the inequity of rewards received for the same action in pairs of familiar dogs. We found that dogs showed significant behavioral differences when tested without food rewards when in the presence of a rewarded partner compared to the baseline and asocial control situations. This indicated that the presence of a rewarded partner matters (Range, Horn, Virányi, & Huber, Proc Natl Acad Sci USA 106(1):340?C345, 2009). In contrast to primates, dogs did not react to differences in the quality of food or effort. In the second study, we analyzed whether individual (motivational or personality) characteristics determined the response of each subject to unequal reward distributions or whether the subject??s responses depended on the specific relationship they had with its partner. We found that individual motivation and the quality of the relationship influenced the dogs?? performance in test conditions, but that these factors varied across the control and reward inequity conditions. Overall, our results suggest that inequity aversion in dogs is conditional on their and their partner??s rewards. Whether inequity aversion is based on the same mechanisms in both humans and non-human primates is still unclear. 相似文献

The aim of our study was to analyse several serum biochemical markers in order to evaluate the discriminant capacity of trace elements individually and jointly in drowning (seawater drowning and freshwater drowning) and their correlation with age, sex, postmortem interval, time in water and concentrations of the trace elements in the drowning medium. Sixty-seven cases of drowning (53 seawater drownings (SWD); 14 freshwater drownings (FWD) and 73 control cases (other asphyxias, n=44, and other causes of death, n=29) were selected according to the scene, cause and circumstances of death, together with autopsy findings. Serum strontium (Sr), magnesium (Mg), sodium (Na), chloride (Cl), calcium (Ca), iron (Fe), urea, creatinine (Cr) and cardiac Troponine T (cTn-T) were measured in the left ventricle (Lv), right ventricle (Rv) and peripheral blood. Lv-Rv differences for each marker and Sr, Mg, Na, Cl, Ca and Fe concentrations in the drowning medium were determinated. Mean concentrations of Sr, Cl and Mg in both ventricles and peripheral serum and Lv-Rv differences and Ca Lv and Na Rv were significantly higher in cases of drowning than for other causes of death. In SWD, Sr, Mg, Ca, Na and Cl were significantly higher in Lv than in Rv as a result of aspirating water. In contrast, haemodilution is evident from the significantly higher levels of Fe and urea in Rv than in Lv in cases of SWD, and from the higher Mg and Cr levels in Rv in FWD. In the case of SWD, serum levels of Sr are confirmed as the best parameter for diagnosis, although other trace elements may also be useful, such as the serum concentrations of Mg and Cl. In the case of FWD, the joint determination of Sr and other biochemical markers, especially Fe, may increase correct diagnosis. 相似文献

In recent years, both scientific and judicial sources have highlighted the need for more knowledge about minutiae variability, in order to improve their statistical application to fingerprint identification. In line with this trend toward improving our knowledge of this subject, the aim of the present study was to calculate the frequency with which 20 types of minutiae appeared in 2780 fingerprint impressions obtained from 278 individuals from two Argentinian population samples (100 individuals from Ramal and 178 from Puna-Quebrada). The different types of minutiae were located, identified, and quantified visually in two areas on the fingerprint, the inside and outside of a circle, the radius of which cut fifteen ridges perpendicularly, starting from the center cut of the axes defining the sectors. The non-equiprobability found in both population samples for the different minutiae types studied demonstrated that the evidential weight provided by these characteristics is not the same when applied in identification processes, whether used quantitatively (numerical standard) or qualitatively (holistic method). The results obtained for both populations were compared statistically with those published previously for a Spanish population sample, which had been collected using the same methodology. This comparison has enabled us to demonstrate, for the first time, the existence of significant differences between populations in minutiae frequencies, independently from the main pattern type. 相似文献

The commissioners of human rights in the Parliament aim at ensuring the protection and formation as well as the development of the culture of human rights with their activities in Hungary and all over the world. What else could be done by the citizens practising their disobedience during the non-violent revolutions in 1989 after Mahatma Gandhi, Martin Luther King and the American Henry David Thoreau? At a first glance, it perhaps seems to be strange to put the following question: what is the connecting link between the role of political law of a public state and the citizens breaking the rules in order to protect the constitutional rights? What will be the result of this comparison? I think, the result is that we can recognize the role of both functions more thoroughly in operating the constitutional state suitably in order to protect the culture of constitutional rights (reactive role) and to develop them (proactive role). 相似文献

The principles of constitutional law as those of many other disciplines seem to develop and to be replaced by new paradigms in the light of globalization. The present article using the genre of constitutional futurology attempts to determine whether this change is real or an illusory impression, and to predict the future of constitutional law and of scholarship reflecting on constitutional issues. A mighty forecast emerges from the interplay of opposing forces. While the withering away of the constitutionalist paradigm is unlikely partly because of the lack of a new generation of legal scholars following new patterns of thinking, partly because there is no reason to assume that the prevalent socioeconomic order would cease to exist , the essay maps a number of possible challenges like genetic engineering or personal computers interconnected in the World Wide Web , which constitutionalists shall expect to face in theory and in practice alike. 相似文献

The duty-of-care requirement cannot be used anymore as the touchstone to differentiate negligence from strict liability because
it can be found in many forms of the latter. Duty of care is smuggled into strict liability hidden under the scope of liability
requirement (traditionally called “proximate causation”). As far as the scope of liability requirement is common to negligence
and to many forms of strict liability, there is a fairly large common ground to both liability rules, and consequently the
marginal Hand formula is applied to both rules. Indeed, under a negligence rule, the marginal Hand formula is applied twice:
first to assess whether or not the defendant did breach his or her duty of care, and, second, to delimit whether or not the
defendant’s behavior was a proximate cause of the harm suffered by the victim. However, under a strict liability rule, the
Hand formula is applied only once when the proximate causation question is raised. Traditional law and economics analysis
has almost always taken the normative question raised by the causation requirement as given, which is a potential major problem
due to the importance of scope of liability or proximate causation in legal practice. Defining the scope of liability, that
is to say, the boundaries of the pool of potential defendants, is the basic legal policy decision for each and every liability
rule. In the normative model presented in this paper, the government first chooses efficient scope of liability, and given
the scope of liability, the government then decides the liability rule and damages that guarantee efficient precaution. In
the article, most known scope of liability rationales developed by both common law and civil law systems are discussed in
order to show the substantial common ground between negligence and strict liability. 相似文献

Household‐level interview data from a probability sample survey conducted in the northeastern Ecuadorian Amazon in 1990 are used to examine the determinants of income and assets among migrant farmers in the agricultural frontier. Multivariate analysis indicates that size of plot owned, proximity to markets, duration of residence, quality of soil, receipt of technical assistance, off‐farm employment and initial wealth positively influence current household income and wealth. More land in cattle pasture is also associated with higher status. Some settlers are prospering relative to others despite variable soil quality, unsustainable land uses, geographic isolation, apparent scarcity of labor, and lack of supportive infrastructure. The article closes with a discussion of implications for policies to assist small farmers, with some consideration of the potential ecological consequences of farmers’ activities. 相似文献
