Principal Component Regression in Spatial Lag Model: Teen Employment in the City of Rosario,Argentina

Teen employment is a very important socioeconomic phenomenon because of its consequences on human capital formation. We assess the relation between teen employment and poverty, education, and unemployment in the city of Rosario, using information from the 2010 Argentina Census disaggregated at census block level. We use two different spatial models: The spatial lag model (SLM) and a linear regression model with the spatial component filtered (filtering model, FM). Given the nature of the variables employed, multicollinearity is an issue. One of the techniques proposed in the literature to deal with multicollinearity problems is principal component regression (PCR). We develop an adaptation of such methodology to be used in the SLM. Both models are estimated using their traditional methodologies (instrumental variables for the SLM and OLS for the FM) and using PCR. Although results are similar between the two models, depending on the methodology used in the estimations they differ greatly. Under traditional methodologies estimations show high variability, instability, and contradictory outcomes, but under PCR, results behave according to the literature.     

European cross-scale spatial planning and territorial frames in the Italian Median Macroregion

This article describes the preliminary outcome of interdisciplinary research that arises from a study by the Italian Ministry of Infrastructures and Transport and the Abruzzo Region (IT) on local development processes in central Italy, and specifically in the Median Macroregion, whose results have been extended to European context. It concerns the European spatial planning, specifically the study of an original interpretative model of European space, called Territorial Frames – TFs, a particular multi-scale infrastructural mesh that connects the ‘local’ territories with ‘global’ ones and that can represent the activating element of processes and policies of spatial development of settlements, of processes of valorization of the productive, naturalistic and landscape sectors. This new model interfaces with the territorial reticular component through the concept of polycentrism, also projecting evolution, and with that of the governance of development projects, using the potential of European Macroregions. The main objective of the research is to feed the topic of spatial planning, oriented to the integration between territories through a cross-scale approach, and to the activation of new processes of sustainable territorial development, with reference to the economically disadvantaged inner areas in a context of Macroregional governance.     

Cyclical downturn or structural disease? The decline of the Italian economy in the last twenty years

Italy is experiencing at present the most serious economic recession of the post-war period. Between 2008 and 2013 national income fell by 9 per cent, per capita incomes by 11 per cent, and industrial production by 25 per cent; and unemployment doubled. In this essay we argue that, while this dramatic situation has been made worse by the policies of ‘expansive austerity’, its origins can be traced back to changes that took place in the 1990s (notably globalization, competition for emerging new markets and the diffusion of new technologies – ICT) to which Italy failed to react speedily or effectively by reorganizing its entire productive system. Instead, many of the reforms that have been introduced with respect to the labour market, for example, have reduced costs but in ways that have encouraged firms to stay in traditional sectors where products are poorly differentiated and of low technology content. If the Italian economy is not to become even weaker, new reforms are urgently needed to encourage innovative investment and push through to completion a restructuring of the industrial system that can no longer be deferred.     

Queering Communia: the politics of positionality when doing research on squatting in Rome

The politics of positionality in relation to sexuality and desire has remained unquestioned when investigating autonomous and alternative spaces, these studies mainly focused on political positionality through the adoption of militant and action-based methodologies. The article tries to fill this void by discussing issues of positionality related to sexuality and desire when doing research on squatting. The main aim is to discuss how entering the field in social movements research through an action-based approach can lead the researcher to involve every aspect of their life, including sexuality and desire. By discussing the case of my PhD research project focused on the re-emergence of squatting initiatives in Rome, the article is aimed at showing how my sexuality, notably my previous engagement in queer politics, has represented an important issue when negotiating with my research partners. When discussing the strategies and activities I adopted, the article plays with the tensions between being queered by the fieldwork and queering it, showing the possibilities of contamination as well as the limits of the politics of positionality.     

Delegitimation and anticommunism in Italian neofascism

Abstract

Although anticommunism was a key element of the identity and political strategy of the neofascist Italian Social Movement (MSI), it has remained a largely unexplored theme in historiographic research. This article reconstructs its origins, developments, and outcomes, from the birth of the MSI in the aftermath of World War II to its dissolution in 1994. Far from being an immutable feature of neofascist political culture, anticommunism took on very different roles and meanings depending on the political climate of republican Italy. In a more radical key, anticommunism both facilitated and hindered political dialogue with the other parties, firstly and foremost the Christian Democratic Party (DC). Taken to excess, anticommunism also accentuated neofascist hostility to democracy. This led to a lasting delegitimation of the MSI at a systemic and ethical-political level, and the party’s alienation in the years of the First Republic.     

Disclosing mineralogical phases in medioeval iron nails by non-destructive neutron techniques

There is not only one methodology for the study of mineralogical phases in archaeological samples. In this paper, we discuss a strategy applied to ancient iron nail samples completely based on non-destructive analyses. The archaeological samples come from the archaeological site of Valle delle Forme (province of Brescia–Italy) and date back to the 1300–1400 ad. Neutron-based techniques, like time-of-flight neutron diffraction and neutron tomography, have been used to determine the mineralogical composition and the structure of nails. An independent check for the assessment of the presence of different mineralogical phases was given by Raman spectroscopy. The combination of different non-destructive techniques has provided very useful information on their chemical composition, nature of the patina and corrosion features of the nails (also in the bulk of the samples).     

Geographic Factors Affecting the Presence of Transhipment Services in Regional Maritime Container Markets

The presence of transhipment services in a region has previously been analyzed relative to ports and shippers with no consideration to the geographical factors of the sea basin serving the region. We hypothesize that attributes related to basin morphology also should be considered, as the processes involved in the maritime container freight market are comparable to processes in other transport markets. We show that transhipment services are relevant in those regions with closed sea basins. This article addresses the following issues: the traditional analytic methods used to determine, directly or indirectly, the presence of transhipment services; the role of transhipment in some geographic regions by estimating the rate of transhipment relative to throughput for each region; and the estimation of a statistical model that can determine the presence of transhipment by means of aggregate variables related to the morphology of a sea basin serving each region and to the socioeconomic characteristics of the region served. La presencia de servicios de transbordo en una región ha sido analizada en relación a los puertos y cargadores, sin considerar los factores geográficos de las cuencas marítimas al servicio de una región. Nuestra hipótesis es que los atributos relacionados a la morfología de las cuencas también deberían tomarse en cuenta, ya que los procesos involucrados en el mercado de contenedores de carga marítima son comparables a los procesos de otros mercados de transporte. Mostramos que los servicios de transbordo son relevantes en aquellas regiones con cuencas marítimas cerradas. El presente artículo aborda los siguientes temas: los métodos analíticos tradicionales generalmente usados para determinar, directa o indirectamente, la presencia de servicios de transbordo; el rol del transbordo en algunas regiones geográficas, a partir de la estimación de las tasas de transbordo relativas a su rendimiento (throughput) en cada región; y la estimación de un modelo estadístico que pueda determinar la presencia de transbordo a partir de variables agregadas relacionadas a la morfología de la cuenca marítima al servicio de cada región, y a las características socioeconómicas de cada región. 区域海运转运服务的分析已经将港口和航运商纳入研究范畴,但忽视了区域海洋盆地地理因素的影响。由于参与海运集装箱货运市场的过程与其他运输市场的过程具有可比性,因而本文认为和海盆形态有关的属性也应考虑在内。研究结果显示,转运服务与那些靠近海盆的区域具有相关性。本文将重点对以下问题进行阐述：过去经常用来直接或间接判断转运服务的传统分析方法;通过估计一个地区相对于自身吞吐量的转运率来判断部分地理区域在转运服务中的角色;通过区域海盆形态和社会经济属性相关的综合变量,构建能够判别转运服务的统计模型.

Determinants of Market Extension in Knowledge-Intensive Business Services: Evidence from a Regional Innovation System

Several studies have emphasized the role of knowledge-intensive business services (KIBS) in fostering innovation in metropolitan areas and regional innovation systems. Such areas are capable of expressing a strong demand for KIBS and consequently stimulate the rise and growth of KIBS. Despite an abundance of literature on KIBS emphasizing the relevance of spatial proximity to customers, many KIBS develop relationships on a broader national or even international scale. No studies have focused explicitly on this apparent discrepancy as yet. The aim of this paper is therefore to fill this theoretical and empirical gap by explaining the firm-level factors relating to the market extension of KIBS within the framework of regional innovation systems. Our analysis is based on a quantitative study on more than 150 KIBS supplying design or communication services located in the Veneto region (north-eastern Italy), an area that can be described as a regional innovation system. Five variables were considered, that is, size, experience, service standardization, investments in network technologies and relational intensity. Our results confirm that three of these variables, but not service standardization and relational intensity, correlate positively with the market extension of KIBS. Policy implications are also discussed.
