Pork-Barrel Politics in Postwar Italy, 1953–94

This article analyzes the political determinants of the distribution of infrastructure expenditures by the Italian government to the country's 92 provinces between 1953 and 1994. Extending implications of theories of legislative behavior to the context of open-list proportional representation, we examine whether individually powerful legislators and ruling parties direct spending to core or marginal electoral districts and whether opposition parties share resources via a norm of universalism. We show that when districts elect politically more powerful deputies from the governing parties, they receive more investments. We interpret this as indicating that legislators with political resources reward their core voters by investing in public works in their districts. The governing parties, by contrast, are not able to discipline their own members of parliament sufficiently to target the parties' areas of core electoral strength. Finally, we find no evidence that a norm of universalism operates to steer resources to areas when the main opposition party gains more votes.     

The Impact of Environmental Factors on the Measurement of Managerial Efficiency in the Italian Waste Management Sector: Framework and Empirical Evidence

ABSTRACT

The public and private sectors are different in terms of ownership, funding, and control. The degree of publicness influences the decision-making processes, strategies, and actions, thus severely impacting the performance levels. This study contributes to the existing literature on managerial efficiency environmental factors by proposing a framework and methodology for estimating the influence of the “publicness effect.” A new method is tested, relying on the combined integration of three different data envelopment analysis models in the Italian waste management sector. Results show that the “publicness effect” accounts for 33.87% of managerial efficiency for public companies and 11.6% for mixed ones.     

Trends in Corruptions Around the World

The problem of measuring changes in corruption internationally is significantly more daunting than that of estimating their levels. We compute trends in corruption for groups of geographically proximate countries, based on the geographic distribution of cases of cross-border bribes, and confirm that geographic variations in corruption are greater than time variations. They are then compared with changes in perceived corruption, as measured by Transparency International’s Corruption Perception Index. We find that these alternative measures are not significantly correlated with each other. Using a panel data estimation technique, we attempt to explain trends in corruption. We only partially confirm results that are obtained when the purpose is to account for their levels in the context of a cross-sectional study. Overall, we conclude that the study of changes in levels of corruption is still in its infancy.     

Deep learning for sex determination: Analyzing over 200,000 panoramic radiographs

The objective of this study is to assess the performance of an innovative AI-powered tool for sex determination using panoramic radiographs (PR) and to explore factors affecting the performance of the convolutional neural network (CNN). The study involved 207,946 panoramic dental X-rays and their corresponding reports from 15 clinical centers in São Paulo, Brazil. The PRs were acquired with four different devices, and 58% of the patients were female. Data preprocessing included anonymizing the exams, extracting pertinent information from the reports, such as sex, age, type of dentition, and number of missing teeth, and organizing the data into a PostgreSQL database. Two neural network architectures, a standard CNN and a ResNet, were utilized for sex classification, with both undergoing hyperparameter tuning and cross-validation to ensure optimal performance. The CNN model achieved 95.02% accuracy in sex estimation, with image resolution being a significant influencing factor. The ResNet model attained over 86% accuracy in subjects older than 6 years and over 96% in those over 16 years. The algorithm performed better on female images, and the area under the curve (AUC) exceeded 96% for most age groups, except the youngest. Accuracy values were also assessed for different dentition types (deciduous, mixed, and permanent) and missing teeth. This study demonstrates the effectiveness of an AI-driven tool for sex determination using PR and emphasizes the role of image resolution, age, and sex in determining the algorithm's performance.     

Incumbency Effects under Proportional Representation: Leaders and Backbenchers in the Postwar Italian Chamber of Deputies

We study incumbency effects for individual legislators from two political parties (Christian Democracy and the Italian Socialist Party) in Italy's lower house of representatives over 10 legislatures (1948–92) elected using open‐list proportional representation. Our analysis finds no reelection advantage for the average incumbent legislator. Only a tiny elite in each party successfully creates an incumbency advantage. We find incumbents advantaged for reselection by their political party. We interpret reselection advantage as a party loyalty premium. Our study depicts a political environment monopolized by party leaders who reward party loyalty but hamper legislators in appealing directly to voters.     

Dimensions of Legislative Conflict: Coalitions,Obstructionism, and Lawmaking in Multiparty Presidential Regimes

This article addresses central issues in multiparty presidential systems: the functioning of legislative coalitions and the dynamics of legislative conflict. Since electoral competition has elements of both positive‐sum (increase in common support) and zero‐sum (exact division of the support) qualities, lawmaking in coalitional systems presents unique challenges. Using legislative data from Brazil, we examine how coalition management and unity affect legislative delay and obstructionism. We find, among others, that: (1) coalition management is pivotal for both faster legislative approval and less obstructionism, but its effect depends on coalition size; and (2) cohesive opposition impedes the legislative process.     

Comparative study of ethanol levels in blood versus bone marrow,vitreous humor,bile and urine

Post-mortem ethanol levels in blood were compared to corresponding levels in rib bone marrow, vitreous humor, urine and bile. In forensic toxicology, a good correlation between blood and a tissue or body fluid is needed to estimate a blood alcohol concentration when blood is unavailable or contaminated. In this study, direct injection and headspace gas-chromatographic techniques were employed to quantitate the ethanol concentrations. Comparable findings by these two techniques showed a reproducibility of results. When the determined bone marrow ethanol levels were corrected for the lipid fraction, a consistent correlation could be established between ethanol levels in blood and bone marrow. The relationship (linearity and ratio range) between ethanol levels in blood and corrected levels in bone marrow was better than that between blood and vitreous humor, bile or urine. This study showed that blood ethanol levels can be predicted by extrapolating the corrected rib bone marrow ethanol level.     

Sufficiency Re-examined: A Capabilities Perspective on the Assessment of Functional Adult Literacy

There is a growing consensus that the dichotomous categories of literate and illiterate should be abandoned. However, the dichotomy has considerable utility in the analysis of educational achievements and inequality in developing countries. Statistics on functional adult literacy are intended to tell us whether people have achieved a minimum level or threshold of functioning necessary for their daily life. We should therefore carefully consider the implications of such change.     

The structures of uncertainty: performativity and unpredictability in economic operations

Abstract

The paper reflects on the presuppositions and consequences of the concept of performativity (understood as the involvement of the observer in the objects and projects he/she describes). The paper proposes a broader notion of performativity, one that not only concerns theory but is also extended to the entire economy, which observes itself in all of its operations. This conception has the advantage of being connected with critical approaches inside economics, which highlight the central role of uncertainty and surprise. It can explain how and why performativity turns into counter-performativity and how financial operators exploit uncertainty when orienting their behaviour, expecting and using the unpredictability of the future.     

Recent interpretations of ideology

The ‘emergence’ of the ‘market’ as the basis of economic and political decision-making has become a main focus of debate within the social sciences since the late 1970s. Even while those opposing the growing centrality of neo-classical economics and market-oriented political discourses remain a significant academic constituency, within their ranks there has been a growing realization that regulatory mechanisms, and in particular the role of the state, have nevertheless been the subject of extensive changes. Alternative schools of thought have argued in terms of the way in which such mechanisms have been refashioned. Regulation has become, in the words of Regini and Majone, ‘transferred’ and the ‘boundaries’ between regulator and regulated ‘changed’: the regulatory process has been seen to shift at the macro/national level and at the micro/enterprise level. While supporting the general argument that it is the boundaries of regulation which are to be discussed, not its presence, we shall nevertheless argue that these changes are, if anything, more contentious and that a set of ironies emerges which politicize regulation even further.
