The eruption of teeth in the mouth is suitable for age estimations during the period when teeth are actively emerging, in the deciduous dentition phase approximately from the age of 6 months to 2.5 years. Estimations of age can be performed simply by counting the number of teeth in the mouth. Reliability of the estimates depends on the reference data available and each population group should preferably have its own standards. In the present study timing of eruption of successive deciduous teeth was studied longitudinally in 129 Finns. The dates of clinical eruption of deciduous teeth were recorded by mothers and checked by dentists. In 40 of the 129 children emergence ages of at the most the four last teeth were based only on semiannual registrations performed by dentists. The main purpose was to provide normal timetables of tooth eruption in small children in forms that are practical in estimations of dental age. No sexual dimorphism existed in the timing of clinical eruption of successive deciduous teeth. The mean age corresponding to the presence of one tooth in the mouth was 7.1 months (S.D.=1.78) and that corresponding to tooth count 19 was 27.8 months (S.D.=3.99). If the chronological age is known, the presented distributions and means with variations make it possible to estimate the degree of advancement or delay in a child’s dental development. If the age of the child is not known, the mean and median ages can be used for estimations of chronological age. However, estimations of age should not be based only on tooth counts because of marked variation also within this homogeneous group. 相似文献

We predict that the Internet will have little effect on political interest, efficacy, and knowledge. We use American National Election Survey monthly panel survey data from 2008 to 2010 to test the role of the Internet. We exploit the fact that the firm who conducted the survey—Knowledge Networks—gives out Internet access for free to those who have never had the Internet before in staggered waves, allowing us to create a novel control-waitlist research design. This allows us to analyze the quasi-random assignment of the Internet to new users for a period of nine months compared to a group that has not yet been given free Internet access. We find that nine months of Internet usage does not increase political interest, political efficacy, or political knowledge. An additional wave done after two and a half years of access also shows little change. Our findings thereby raise serious doubts about the previous observational findings of the benefits of Internet usage for political interest, efficacy, and knowledge. 相似文献

Drawing upon concepts from prior research that emphasize race and gender stereotyping, the present research compares how delinquent and “neglected” types of offenses (i.e. status offenses, probation violations, youth charged with contempt) are treated across three juvenile court outcomes. Beyond how offense type may directly impact case outcomes, we also investigated whether race and gender influenced juvenile justice processing within each offense type. Using data from two Mid-Atlantic States, results indicated that type of offense, race, and gender resulted in both severe and lenient case outcomes depending on the stage examined. By including different types of offenses that represent a significant percentage of youth that have been relatively neglected in prior research, the current study provides greater insight into the contexts of race and gender disparities in juvenile justice decision-making. The implications of the findings and directions for future research are also discussed. 相似文献

Most countries struggle to implement CO2 reducing policies. Implementation is politically difficult since it typically forces politicians to trade-off different concerns. The literature on how parties and members of parliament (MPs) handle these trade-offs is sparse. We use structural topic models to study how MPs in an oil dependent environment responded to a shock in the oil price that created spatially concentrated costs of climate policies. We leverage the rapid oil price drop between parliamentary sessions and MPs’ constituency adherence in a difference-in-differences framework to identify if MPs respond differently to variation in the salience of trade-offs. We find that MPs facing high political costs of climate policies tried to avoid environmental topics, while less affected MPs talked more about investments in green energy when the oil price declined. Our results suggest that the oil price bust created a ‘window of opportunity’ for advocates of the ‘ green shift’. 相似文献

Ever since the Great Recession, public debt has become politicised. Some research suggests that citizens are fiscally conservative, while other research shows that they punish governments for implementing fiscal consolidation. This begs the question of whether and how much citizens care about debt. We argue that debt is not a priority for citizens because reducing it involves spending and tax trade-offs. Using a split-sample experiment and a conjoint experiment in four European countries, we show that fiscal consolidation at the cost of spending cuts or taxes hikes is less popular than commonly assumed. Revenue-based consolidation is especially unpopular, but expenditure-based consolidation is also contested. Moreover, the public has clear fiscal policy priorities: People do not favour lower debt and taxes, but they support higher progressive taxes to pay for more government spending. The article furthers our understanding of public opinion on fiscal policies and the likely political consequences of austerity. 相似文献
