This article builds a composite index, the Central American Integration Index (IIC-AMPI), to measure economic integration. This index utilises a robust methodology and conceptual framework. The study shows that IIC-AMPI is responsive to variable changes and resistant to outliers. The findings indicate that the Deep Integration Process initiative dominates the current integration trend, as seen in the regional average score from 2015 to 2017, aligning with Guatemala and Honduras. Nicaragua demonstrates the most consistent progress, while Panama lags behind. The evidence supports the Customs Union as Central America's future integration path, highlighting the index's ability to capture the dynamic reality of economic integration. 相似文献

Abstract. The empirical work concerning the relation between economic conditions and the popularity of parties in the Federal Republic of Germany is surveyed. Research in this area started in 1971. During the first ten years (only) traditional econometrics were used. It was shown that the lower unemployment and/or inflation, the higher – ceteris paribus – the popularity of the leading party in government. In the 1980s, using modern time series methods, the validity of the earlier results has been questioned. However, it has been shown that such a relation can also be detected using modern time series techniques. Finally, it is asked whether the observed voting behaviour is consistent with the theory of rational expectations. Using popularity data, the hypothesis of rational expectations can be rejected. Thus, West German voters do not behave rationally in the sense used by Muth. 相似文献

The authors evaluated the usefulness of the postmortem biochemical analysis of ionic ratios in different parts of the heart and their relation to cardiac damage caused by chest trauma, as observed by anatomopathologic study. Fifty-nine 59 cases were studied, selected from routine necropsies, and samples were taken from different sites of cardiac tissue. The cause of death was trauma in 40 cases and nontraumatic causes in 19 cases. The object of this study was to analyze the levels of Na+, K+, Ca+2, Mg+2, and Zn+2 in different zones of the heart, and the relationship between intracellular and extracellular ion ratios and the different causes of death and any anatomopathologic alterations observed. The biochemical tests revealed a possible relation between the ionic values and cause of death. Alterations in cell membrane permeability and corresponding modification of the ionic ratios were produced earlier than histologic alterations, which need longer to establish themselves whether or not they follow a traumatic process. 相似文献

Forensic pathologists may be asked to identify the ethnic group and gender of a cranium of unknown origin. An analysis of the maxillary sinus--its volume, shape, and dimensions in dried crania of different ethnic and gender groups (European and Zulu male and female)--was conducted to establish a new approach. A variation in maxillary sinus volume may mean a variation in anatomic landmarks between the groups. Ethnic and gender variations in the shape of the maxillary sinus of the crania were investigated. This research was further extended to predict the gender and ethnic group from an unknown cranium to make this research valuable to the fields of forensic pathology and anthropology. Helical, multislice computed tomography was performed using 1-mm coronal slices. The area for each slice was obtained by tracing the outline of each slice. The computed tomographic machine calculated a volume by totalling the slices for each sinus. Advanced computer methodology including a neural network was designed and applied to search for classification patterns in data. A discriminant analysis was performed to improve classification results. Ethnic and gender variations were found in the different groups, and the predictive role of the maxillary sinus in ethnic classification was established. It was found that European crania had significantly larger antral volumes than Zulu crania, and males had larger volumes than females. Dimensions of European sinuses were larger than those of Zulu sinuses. The medial antral wall of the sinus allowed for ethnic classification. The discriminant analysis allowed for a very successful 90% ethnic prediction, while gender prediction was ultimately 79%. The measurements taken and the formulae created in this research will be valuable to those in the field who are seeking to ethnically classify a cranium into one or another ethic group. This research aims to be an aid in identification, as well as a starting point for other scientific studies based on other ethnic groups. Perhaps its true value will lie in confirming ethnicity by adding to existing criteria. It must be noted that this classification is based on actual measurements and therefore eliminates the some of the subjectivity present in current methods of ethnic classification. 相似文献

Zunächst werden die theoretischen Überlegungen kurz dargelegt, die zur Entscheidungs‐ bzw. zur Mobilisierungshypothese führen. Zudem wird die Theorie des ‘expressiven Wählens’ vorgestellt, und es wird auf zwei weitere Hypothesen über Bestimmungsgründe der Stimmbeteiligung eingegangen. Danach wird der Schätzansatz beschrieben, bevor wir uns mit den empirischen Ergebnissen beschäftigen. Sie sprechen nicht nur sehr stark für die Mobilisierungs‐ und gegen die Entscheidungshypothese, sondern zumindest bei den fakultativen Referenden spielen auch die erwarteten (bzw. befürchteten) finanziellen Auswirkungen eine entscheidende Rolle. Allerdings sind sie nur bedingt mit der Theorie des expressiven Wählens vereinbar. 相似文献
