the Labor Market of Italian Politicians, Second Version

We analyze the career profiles of Italian legislators in the post-war period. Using a unique, newly collected dataset that contains detailed information on all the politicians who have been elected to the Italian Parliament between 1948 and 2008, we address a number of important issues that pertain to their career paths prior to election to Parliament, their parliamentary careers, and their post-Parliament employment. Our data span two institutional regimes: Italy’s First Republic (1948-1994) and the Second Republic (1994-present), characterized by different electoral rules and party structures. We first present a brief overview of the Italian political system. We then provide a comprehensive view of the career profiles of Italian legislators over the entire sample period, and highlight the major differences between the First and the Second Republic. We also compare the profiles of Italian legislators to those of the members of the United States Congress. We then use our data to address a number of questions that pertain to the selection of Italian politicians, their labor market, and their overall quality. We also draw some general conclusions that contribute to the debate about the relative efficacy and desirability of alternative policies regarding the selection and the compensation of elected representatives.politicians, parties, political careers

The Labor Market of Italian Politicians

Like voters (the represented), politicians (the representees) are the heart and soul of representative democracy. But isnt being a politician just like any other job? After we get past the rhetoric, is politics any different than other occupations? In the political sector, voters, parties and politicians represent the counterparts of consumers, firms and workers/managers in the market sector. In fact, the analogy is much deeper than it may appear at first sight. In the market sector, consumers determine to a large extent the success of a firm and ultimately the managements fate. However, managers are chosen by the firms, which typically have an objective that is different from those of consumers and managers. Likewise, while in all democratic systems the voters ultimately determine who is elected, it is typically the case that political parties nominate candidates for public office. Furthermore, the objectives of voters and parties with respect to the selection of candidates may differ, and are constrained by the career ambitions of individuals with political aspirations. But then, what really makes a career in the political sector different from a career in any other economic sector? There are at least three distinctive features that characterize the labor market in the political sector. First, politicians are typically under the spotlight, receiving the attention of the media and of a variety of citizens organizations. This makes politics a showcase, where politicians in office can display their political skills, while it might be more difficult for individuals working in the market sector to reveal their market ability. Second, inter-party competition for potential politicians is likely to be of secondary importance, as ideological preferences are more likely to attract individuals toward specific parties at the beginning of their political careers. Third, it is often the case that political parties take care of their losers by reserving partys positions to defeated incumbents. As a result, while individual careers within the political sector are inevitably linked to the opportunities available within parties, the extent to which individual endowments of political and market skills are correlated, or experience in the political (market) sector is also valuable in the market (political) sector, links the labor markets of the two sectors. This link affects the selection of politicians, the politicians careers, and the relationship between parties and voters.voters, parties, political sector

Consumer acceptance of Italian or New Zealander lamb meat: an Italian case study

A Central location test was performed to compare heavy Apennine lamb meat to New Zealander lamb meat in order to create a Protected Geographical Indication for lamb meat. Roasted New-Zealander and heavy Apennine lamb legs were tested by 106 consumers according to the following experimental plan: blind phase (B) without any possibility to recognize the meat type tasted, expected phase (E) in which were described the characteristics of the two types of meat without tasting, informed phase (I) in which the tasted meat was recognized in provenience. Results showed in a nine point scale of appreciation for flavour, juiciness and overall pleasure, the highest values in Apennine lamb meat. B test showed the highest value for overall pleasure (P<0.01). Interaction, Italian lamb x Informed test showed the highest values for all the parameters except for overall liking for which Italian lamb x E test showed the highest values. About foreign lamb meat B test showed higher values than I and E test. Information about lamb meat origin showed disconfirmation for tenderness in Italian lamb meat. Foreign lamb meat showed a positive disconfirmation for flavour and overall pleasure, that confirm the better perception by consumers in blind consumption than in the informed one

Genetic characterization of Appenninica sheep breed by microsatellites

The conservation of genetic variability is one of the main objectives in the field of genetics applied to domestic livestock. A strong input in that direction was made by molecular biology techniques. Among molecular markers nowadays available, microsatellites are particularly appreciated and widely utilized for the study of animal genome. In this study, a genetic characterization of Appenninica sheep breed was carried out with thirty microsatellite markers; the genetic relationships between Appenninica and three Italian merinos-derived breeds were also investigated. The results show a good genetic variability of Appenninica and all the other studied breeds. At the same time, the genetic identity of each breed is confirmed. These molecular data can be utilized to improve the present selection schemes and the plans to preserve the genetic diversit

Statistical Parameters of Steel Rebars of Reinforced Concrete Existing Structures

Historical and cognitive investigations supported by in-situ and/or laboratory tests are needed for a robust reliability assessment of existing structures. Indeed, an adequate knowledge of material properties and their statistical description is the basis for carrying out accurate reliability analyses and verifications on the investigated structures. In this paper, a procedure for the definition of pdfs of mechanical parameters of steel rebars is proposed based on secondary experimental test data. This information is very helpful for the reliability assessment of existing r.c. buildings, where estimation of statistical parameters of mechanical properties of steel reinforcement is very difficult. In fact. It must be highlighted on the one hand that direct information about the examined structure are commonly not sufficient, on the other hand that the number of rebar samples extracted from the structure, if available, is so limited that it does not allow a complete statistical analysis. The first step has been the collection of experimental acceptance tests carried out by Department of Civil and Industrial Engineering of University of Pisa on steel rebars of reinforced concrete (r.c.) structures during the 1960s. The yield strength and the tensile strength are extrapolated for each sample defining a significant database of experimental test results for existing r.c. structures. Then, probability distribution models for the mechanical properties of steel reinforcement have been defined as already done by the authors for concrete strength. A cluster analysis has been carried out based on the Gaussian Mixture Model applying the Expectation-Maximization algorithm to identify homogeneous material classes and their associated pdfs of material mechanical parameters. The main advantage of proposed procedure consists in its “blindness”, In fact, not requiring subjective information like pre-classification of data, the methodology is not sensitive to alterations caused by engineering judgement or by inexact identification of declared strength class of the tested samples, due for example to downgraded materials

Mitochondrial DNA Variations in Colombian Creole Sheep Confirm an Iberian Origin and Shed Light on the Dynamics of Introduction Events of African Genotypes

The genetic origins and diversity of Creole sheep from five regions of Colombia were investigated based on mitochondrial DNA (mtDNA) variations across 89 sequences from five breeds: one wool Creole sheep (CL) and four hair Creole sheep, including Ethiopian (OPCE), Sudan (OPCS), Pelibuey (OPCP) and Wayúu (OPCW). A global comparison was done using 62 haplotypes from Iberian, African, Indian, Caribbean, Mexican, Caucasian and European sheep based on sequences retrieved from GenBank. This study aimed to identify the maternal origin of Colombian Creole sheep and their genetic relationships at a global level. The results showed 31 different haplotypes from Colombian Creole sheep, which can be assigned to maternal lineage B, the most common lineage found in European sheep breeds and the only one found in several Iberian breed (e.g., Churra, Spanish Merino) that most likely participated in the Creole formation. Additional analyses showed that wool and hair sheep retained a broad genetic identity despite being geographically separated. The global-level phylogenetic analysis revealed that Colombian Creole sheep belong to a distinct and defined genetic lineage that is likely the result of a founder effect with ecotypes of Iberian descent and the subsequent introduction of foreign breeds. This is consistent with historical reports on the presence of sheep in South America and, particularly, Colombia

Sexual Dimorphism and Breed Characterization of Creole Hens through Biometric Canonical Discriminant Analysis across Ecuadorian Agroecological Areas

Despite Ecuador having a wide biodiversity of zootechnical species, characterization studies of these genetic resources are scarce. The objective of this research was to perform the biometric characterization of the Creole hen population through 14 quantitative zoometric measures. We evaluated 207 hens and 37 roosters from Ecuador’s three agro-ecological regions: the Sierra (highlands) region (Bolivar, Chimborazo, Tungurahua and Cotopaxi provinces); the Costa (coastal) region (Guayas); and the Oriente Amazonian region (Morona Santiago). Sexual dimorphism was assessed using one-way analysis of variance (ANOVA). Body dimensions were generally significantly higher for males (p < 0.05), especially for length of head, beak, neck, dorsum, tarsus, thigh, leg, and middle finger. Then, individuals were biometrically clustered into populations after a stepwise canonical discriminant analysis (CDA) computing interpopulation Mahalanobis distances. Agroecologically-based structured populations were identified when zoometrical criteria were used to classify the animals. Cotopaxi and Tungurahua provinces were reported to be the most distant from the rest, with a slight differentiation of the Morona Santiago province population from those in Guayas, Chimborazo and Bolívar. Conclusively, Ecuadorian Creole hens were higher than longer contrasting light hen breeds, which favors their dual-purpose aptitude. Hence, the development of selection programs aimed at Ecuadorian differentiated entity of production of eggs and meat across agro-ecological areas is feasible
