Accurate age estimation has always been a problem for forensic scientists, and apposition of secondary dentine is often used as an indicator of age. Cameriere et al. studied the pulp/tooth area ratio by peri-apical X-ray images of the canines, to observe the apposition of secondary dentine. The present study examines the application of this technique in a Mexican identified sample coming from the Department of Physical Anthropology of the INAH, at Mexico City. The main aim of this work is to test the reliability of this method in a skeletal sample of a specific population, different from the samples used for its development. The obtained regression model explained 96.2% of total variance (R(2) = 0.962) with a standard error of estimate of 1.909 and a standard deviation of 1.947. These results demonstrate great reliability and that the age/secondary dentine relationship is not variable in this specific population. 相似文献

This article examines how parties organize legislative speech. Electoral incentives and legislative institutions affect speech participation. When electoral systems create personal vote‐seeking incentives, parties are less concerned with screening speeches and more supportive of members seeking to garner name recognition. But in many countries, legislative rules and norms constrain opportunities for individual position taking during the lawmaking debates. We argue that parties resolve this dilemma by organizing speech participation into nonlegislative speeches and lawmaking debates. In each instance, different types of legislators are more likely to speak. We examine the case of Chile and test the implications of our theory with data on congressional speeches. 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

Sex determination is an important task in physical anthropology and forensic medicine. The study sample comprised 121 individuals of known sex, age, and cause of death from San Jose cemetery in Granada (Spain). Eight dimensions were analyzed, and discriminant function analysis was performed for each vertebra to obtain discriminating functions and study the percentage of correct assignations of these functions. The percentage accuracy was approximately 80% for both vertebrae, but varied according to the sex, being higher for the 7th cervical in males and higher for the 12th thoracic in females. As reported in other populations, the greatest dimorphism values were found for the length of the inferior surface of the vertebral body and the width and length of the vertebral foramen of the 7th cervical vertebra and for the length of the inferior surface of the vertebral body of the 12th thoracic vertebra. 相似文献

Disentangling the Role of Ideology and Partisanship in Legislative Voting: Evidence from Argentina 下载免费PDF全文

We present a novel approach to disentangle the effects of ideology, partisanship, and constituency pressures on roll‐call voting. First, we place voters and legislators on a common ideological space. Next, we use roll‐call data to identify the partisan influence on legislators' behavior. Finally, we use a structural equation model to account for these separate effects on legislative voting. We rely on public opinion data and a survey of Argentine legislators conducted in 2007–08. Our findings indicate that partisanship is the most important determinant of legislative voting, leaving little room for personal ideological position to affect legislators' behavior. 相似文献

This paper examines the approval of government bills in Chile, evaluating the effect of presidential prerogatives and policy substance, and considering both bill-specific and contextual effects. The results show that presidential prerogatives over financial policy, as well as the ability to affect the congressional agenda through urgent bill scheduling, significantly influence government bill approval. As expected, government success is enhanced during the honeymoon period. However, changes in public approval of the president do not appear to exert a significant effect on the passage of presidential bills. 相似文献

This article extends the analysis of political parties in electorally volatile and organizationally weak party systems by evaluating two implications centered on legislative voting behavior. First, it examines whether disunity prevails where weakness of programmatic and electoral commonalities abound. Second, it analyzes whether inchoate party systems weaken the ability of government parties to control the congressional agenda. The empirical analysis centers on Peru, a classic example of a weakly institutionalized party system, and how its legislative parties compare to those of Argentina, Brazil, Chile, and the United States. The results lend support to the view that lower unity characterizes weakly institutionalized settings. The agenda‐setting power of government parties, however, appears to be influenced more by the majority status of the government than by the level of party system institutionalization. 相似文献

Legislators in presidential countries use a variety of mechanisms to advance their electoral careers and connect with relevant constituents. The most frequently studied activities are bill initiation, co-sponsoring, and legislative speeches. In this paper, the authors examine legislators’ information requests (i.e. parliamentary questions) to the government, which have been studied in some parliamentary countries but remain largely unscrutinised in presidential countries. The authors focus on the case of Chile – where strong and cohesive national parties coexist with electoral incentives that emphasise the personal vote – to examine the links between party responsiveness and legislators’ efforts to connect with their electoral constituencies. Making use of a new database of parliamentary questions and a comprehensive sample of geographical references, the authors examine how legislators use this mechanism to forge connections with voters, and find that targeted activities tend to increase as a function of electoral insecurity and progressive ambition. 相似文献

The concept of marketing has evolved significantly, as have its applications in various sectors, including services. Diverse opinions have been expressed for and against the use of marketing techniques in public administration. In this paper, we present a conceptual and methodological review of the main contributions made by marketing to the public sector, measuring variables and related concepts that determine public satisfaction with public services. These elements, termed key drivers of opinion, were measured by reference to the information provided by the Spanish Sociological Research Centre (CIS), and provide an alternative way to display and analyse the data of interest, through perception models and figures using multivariate factor analysis. In this study, the components or factors containing the main drivers of opinion were found to be, on the one hand, commitment to efficient service, and on the other, user convenience. 相似文献
