Recent studies have shown that gender is the personal aspect that mostly affects mobility patterns and travel behaviors. It has been observed, for instance, that female perception of unsafety and insecurity when traveling using public transport forces them to make unwanted travel choices, such as avoiding traveling at certain times of day and to specific destinations. In order to improve the attractiveness of public transport services, this gender gap must not be overlooked. This paper aims at contributing to research in gendered mobility by investigating differences in safety and security perceptions in railway stations, and by identifying which policies could be effective in bridging any existing gap. The methodology includes the collection of disaggregate data through a mixed Revealed Preference/Stated Preference survey, and the estimation of fixed and random parameters behavioral models. Results from a medium-sized Italian railway station show that female travelers feel safer in the presence of other people; they prefer intermodal infrastructures close to the entrance of the station and commercial activities in the internal premises. Moreover, unlike male travelers, they do not appreciate the presence of hedges and greenery outside stations.

Role Of The Principal

Purpose: We explored the practices and understandings around using disaggregated data to inform instruction of 18 principals from three Midwestern school districts. Research Method: This qualitative study used one-on-one semistructured interviews with the principals focusing on how they disaggregate data in practice. The protocol included general questions about principals’ data practices as well as specific questions around disaggregation. Initial inductive coding began with principals’ direct responses to specific questions around disaggregation, and then emerging themes were used to analyze the entire transcripts. Findings: Participants were more likely to talk about disaggregation in relation to performance (by teacher, by grade level, etc.) than by subgroup (by race/ethnicity, by gender, etc.). Further analysis highlighted principals’ purposes for disaggregating data that focused on identifying low performance on standards-based assessments, as well as the challenges they faced, particularly in terms of technical skills and software. Implications for Research and Practice: We conclude with a discussion of how disaggregation could support or challenge equity-focused leadership, with implications for policy, practice, and preparation. We consider the role of the principal in identifying inequitable patterns versus focusing on individual students, and different ways that equity can become part of regular leadership practice.

Abstract The analysis of local governments as potential devices to improve the efficiency of public sectors becomes particularly important for Italy, given both the relevant post-war growth of its public sector and the supra-national constraints imposed by the European Monetary Union. The purpose of this paper is to investigate into the relationships between central and local governments’ revenue-expenditure patterns, by considering disaggregate data on Regioni, Province and Comuni. The empirical results exhibit a high elasticity of local expenditure with respect to State transfers, and insignificance of local taxation revenues in determining local expenditure, as a strong version of the so-called flypaper effect. The identification of a second cointegrating vector between State transfers and own resources, with an ambiguous sign, is another remarkable feature of the Italian fiscal federalism, and points to die need for a more efficient monitoring in allocating State transfers.
