Welfare provision in Sweden and the dominant position of the Sap

There have been almost fifty years since Harry Eckstein' s classic monograph, A Theory of Stable Democracy (Princeton, 1961), where he sketched out the basic tenets of the “congruence theory”, which was to become one of the most important and innovative contributions to understanding democratic rule. His next work, Division and Cohesion in Democracy, (Princeton University Press: 1966) is designed to serve as a plausibility probe for this 'theory' (ftn.) and is a case study of a Northern democratic system, Norway. What is more, this line of his work best exemplifies the contribution Eckstein brought to the methodology of comparative politics through his seminal article, “ “Case Study and Theory in Political Science” ” (in Greenstein and Polsby, eds., Handbook of Political Science, 1975), on the importance of the case study as an approach to empirical theory. This article demonstrates the special utility of “crucial case studies” in testing theory, thereby undermining the accepted wisdom in comparative research that the larger the number of cases the better. Although not along the same lines, but shifting the case study unit of research, I intend to take up here the challenge and build upon an equally unique political system, the Swedish one. Bearing in mind the peculiarities of the Swedish political system, my unit of analysis is going to be further restricted to the Swedish Social Democratic Party, the Svenska Arbetare Partiet. However, my research stays within the methodological framework of the case study theory inasmuch as it focuses on a single political system and party. The Swedish SAP endurance in government office and its electoral success throughout half a century (ftn. As of the 1991 election, there were about 56 years - more than half century - of interrupted social democratic "reign" in Sweden.) are undeniably a performance no other Social Democrat party has yet achieved in democratic conditions. Therefore, it is legitimate to inquire about the exceptionality of this unique political power combination. Which were the different components of this dominance power position, which made possible for SAP's governmental office stamina? I will argue here that it was the end-product of a combination of multifarious factors such as a key position in the party system, strong party leadership and organization, a carefully designed strategy regarding class politics and welfare policy. My research is divided into three main parts, the historical incursion, the 'welfare' part and the 'environment' part. The first part is a historical account of the main political events and issues, which are relevant for my case study. Chapter 2 is devoted to the historical events unfolding in the 1920-1960 period: the Saltsjoebaden Agreement, the series of workers' strikes in the 1920s and SAP's inception. It exposes SAP's ascent to power in the mid 1930s and the party's ensuing strategies for winning and keeping political office, that is its economic program and key economic goals. The following chapter - chapter 3 - explores the next period, i.e. the period from 1960s to 1990s and covers the party's troubled political times, its peak and the beginnings of the decline. The 1960s are relevant for SAP's planning of a long term economic strategy - the Rehn Meidner model, a new way of macroeconomic steering, based on the Keynesian model, but adapted to the new economic realities of welfare capitalist societies. The second and third parts of this study develop several hypotheses related to SAP's 'dominant position' (endurance in politics and in office) and test them afterwards. Mainly, the twin issues of economics and environment are raised and their political relevance for the party analyzed. On one hand, globalization and its spillover effects over the Swedish welfare system are important causal factors in explaining the transformative social-economic challenges the party had to put up with. On the other hand, Europeanization and environmental change influenced to a great deal SAP's foreign policy choices and its domestic electoral strategies. The implications of globalization on the Swedish welfare system will make the subject of two chapters - chapters four and five, respectively, whereupon the Europeanization consequences will be treated at length in the third part of this work - chapters six and seven, respectively. Apparently, at first sight, the link between foreign policy and electoral strategy is difficult to prove and uncanny, in the least. However, in the SAP's case there is a bulk of literature and public opinion statistical data able to show that governmental domestic policy and party politics are in a tight dependence to foreign policy decisions and sovereignty issues. Again, these country characteristics and peculiar causal relationships are outlined in the first chapters and explained in the second and third parts. The sixth chapter explores the presupposed relationship between Europeanization and environmental policy, on one hand, and SAP's environmental policy formulation and simultaneous agenda-setting at the international level, on the other hand. This chapter describes Swedish leadership in environmental policy formulation on two simultaneous fronts and across two different time spans. The last chapter, chapter eight - while trying to develop a conclusion, explores the alternative theories plausible in explaining the outlined hypotheses and points out the reasons why these theories do not fit as valid alternative explanation to my systemic corporatism thesis as the main causal factor determining SAP's 'dominant position'. Among the alternative theories, I would consider Traedgaardh L. and Bo Rothstein's historical exceptionalism thesis and the public opinion thesis, which alone are not able to explain the half century social democratic endurance in government in the Swedish case.

Computational analyses on the structure-function relation in ion channels

Ion channels are protein molecules, embedded in the lipid bilayer of the cell membranes. They act as powerful sensing elements switching chemicalphysical stimuli into ion-fluxes. At a glance, ion channels are water-filled pores, which can open and close in response to different stimuli (gating), and one once open select the permeating ion species (selectivity). They play a crucial role in several physiological functions, like nerve transmission, muscular contraction, and secretion. Besides, ion channels can be used in technological applications for different purpose (sensing of organic molecules, DNA sequencing). As a result, there is remarkable interest in understanding the molecular determinants of the channel functioning. Nowadays, both the functional and the structural characteristics of ion channels can be experimentally solved. The purpose of this thesis was to investigate the structure-function relation in ion channels, by computational techniques. Most of the analyses focused on the mechanisms of ion conduction, and the numerical methodologies to compute the channel conductance. The standard techniques for atomistic simulation of complex molecular systems (Molecular Dynamics) cannot be routinely used to calculate ion fluxes in membrane channels, because of the high computational resources needed. The main step forward of the PhD research activity was the development of a computational algorithm for the calculation of ion fluxes in protein channels. The algorithm - based on the electrodiffusion theory - is computational inexpensive, and was used for an extensive analysis on the molecular determinants of the channel conductance. The first record of ion-fluxes through a single protein channel dates back to 1976, and since then measuring the single channel conductance has become a standard experimental procedure. Chapter 1 introduces ion channels, and the experimental techniques used to measure the channel currents. The abundance of functional data (channel currents) does not match with an equal abundance of structural data. The bacterial potassium channel KcsA was the first selective ion channels to be experimentally solved (1998), and after KcsA the structures of four different potassium channels were revealed. These experimental data inspired a new era in ion channel modeling. Once the atomic structures of channels are known, it is possible to define mathematical models based on physical descriptions of the molecular systems. These physically based models can provide an atomic description of ion channel functioning, and predict the effect of structural changes. Chapter 2 introduces the computation methods used throughout the thesis to model ion channels functioning at the atomic level. In Chapter 3 and Chapter 4 the ion conduction through potassium channels is analyzed, by an approach based on the Poisson-Nernst-Planck electrodiffusion theory. In the electrodiffusion theory ion conduction is modeled by the drift-diffusion equations, thus describing the ion distributions by continuum functions. The numerical solver of the Poisson- Nernst-Planck equations was tested in the KcsA potassium channel (Chapter 3), and then used to analyze how the atomic structure of the intracellular vestibule of potassium channels affects the conductance (Chapter 4). As a major result, a correlation between the channel conductance and the potassium concentration in the intracellular vestibule emerged. The atomic structure of the channel modulates the potassium concentration in the vestibule, thus its conductance. This mechanism explains the phenotype of the BK potassium channels, a sub-family of potassium channels with high single channel conductance. The functional role of the intracellular vestibule is also the subject of Chapter 5, where the affinity of the potassium channels hEag1 (involved in tumour-cell proliferation) and hErg (important in the cardiac cycle) for several pharmaceutical drugs was compared. Both experimental measurements and molecular modeling were used in order to identify differences in the blocking mechanism of the two channels, which could be exploited in the synthesis of selective blockers. The experimental data pointed out the different role of residue mutations in the blockage of hEag1 and hErg, and the molecular modeling provided a possible explanation based on different binding sites in the intracellular vestibule. Modeling ion channels at the molecular levels relates the functioning of a channel to its atomic structure (Chapters 3-5), and can also be useful to predict the structure of ion channels (Chapter 6-7). In Chapter 6 the structure of the KcsA potassium channel depleted from potassium ions is analyzed by molecular dynamics simulations. Recently, a surprisingly high osmotic permeability of the KcsA channel was experimentally measured. All the available crystallographic structure of KcsA refers to a channel occupied by potassium ions. To conduct water molecules potassium ions must be expelled from KcsA. The structure of the potassium-depleted KcsA channel and the mechanism of water permeation are still unknown, and have been investigated by numerical simulations. Molecular dynamics of KcsA identified a possible atomic structure of the potassium-depleted KcsA channel, and a mechanism for water permeation. The depletion from potassium ions is an extreme situation for potassium channels, unlikely in physiological conditions. However, the simulation of such an extreme condition could help to identify the structural conformations, so the functional states, accessible to potassium ion channels. The last chapter of the thesis deals with the atomic structure of the !- Hemolysin channel. !-Hemolysin is the major determinant of the Staphylococcus Aureus toxicity, and is also the prototype channel for a possible usage in technological applications. The atomic structure of !- Hemolysin was revealed by X-Ray crystallography, but several experimental evidences suggest the presence of an alternative atomic structure. This alternative structure was predicted, combining experimental measurements of single channel currents and numerical simulations. This thesis is organized in two parts, in the first part an overview on ion channels and on the numerical methods adopted throughout the thesis is provided, while the second part describes the research projects tackled in the course of the PhD programme. The aim of the research activity was to relate the functional characteristics of ion channels to their atomic structure. In presenting the different research projects, the role of numerical simulations to analyze the structure-function relation in ion channels is highlighted.

Competitività in sostenibilità urbana e territoriale. L’Emilia Romagna, regione d’Europa

The thesis in Urban and Regional Geography titled “URBAN AND TERRITORIAL COMPETITIVENESS IN SUSTAINABILITY. EMILIA-ROMAGNA, REGION OF EUROPE” is divided into two sections. Section one is additionally composed by two chapters (chap. 1 and 2) and deals with theoretical and gnosiological issues. Section two, of two more chapters (chap. 3 and 4), provides practical contributions: these issues give explanatory patterns to interpret the performances of emiliano-romagnoli urban systems. Chapter one is an introductory chapter. It analyzes globalization that involves a larger and larger number of cities, rich or poor. It also considers the so called “digital divide” either as one of the major phenomena of this unhomogeneous development or as an interesting gnosiological and practical challenge of geography. Globalization is now involving all the cities, large or small, but the small ones have higher risks of exclusion: it depends on their more fragile socio-economic, cultural, and environmental urban structure. That’s why European Union (chapter two) promotes policies and endows politics to sustain cities, because urban systems are the basis for the territorial development. So, European, national and local Institutions are firmly interested in promoting urban and local interventions and projects. Section two deals with economic-geography methods, which consists on collecting indicators and the benchmarking methodology. It also specifically analyzes the urban systems of Emilia-Romagna. Consequences of the globalization on the cities are interpreted with a study of their local resources, intended as potentials for their development. The STeMA approach, proposed by Professor Maria Prezioso (University of Roma, “Tor Vergata”) and used by the ESPON (European Spatial Program Observation Network) project, describes the main “determinants” of the territorial and urban development. These are easily comparable to one another (similar or better performing). This approach achieves two goals. On one hand, it is possible to analyze every urban system in its all main characteristics and to preserve its historical and cultural factors. On another hand, each city is “knowable” and “understandable” by all scholars, as it is objectively comparable. So, urban planners can propose specific “multi-level” and “multi-varied” programs of governance. These will face globalization by exalting local empowerment.

Characterization of L-type Calcium Channel Binding-Site of a new class of Calcium modulators by a Multidisciplinary approach

Many potential diltiazem related L-VDCC blockers were developed using a multidisciplinary approach. This current study was to investigate and compare diltiazem with to the newly developed compounds by mouse Langendorff-perfused heart, Ca2+-transient and on recombinant L-VDCC. Twenty particular compounds were selected by the ligand-based virtual screening procedure (LBVS). From these compounds, five of them (5b, M2, M7, M8 and P1) showed a potent and selective inotropic activity on guinea-pig left atria driven 1 Hz. Further assays displayed an interesting negative inotropic effect of M2, M8, P1 and M7 on guinea pig isolated left papillary muscle driven at 1 Hz, a relevant vasorelaxant activity of 5b, M2, M7, M8 and P1 on K+-depolarized guinea-pig ileum longitudinal smooth muscle and a significant inhibition of contraction of 5b, M2, M8 and P1 on carbachol stimulated ileum longitudinal smooth muscle. Wild-type human heart and rabbit lung α1 subunits were expressed (combined with the regulatory α2δ and β3 subunits) in Xenopus Leavis oocytes using a two-electrode voltage clamp technique. Diltiazem is a benzothiazepine Ca2+ channel blocker used clinically for its antihypertensive and antiarrhythmic effects. Previous radioligand binding assays revealed a complex interaction with the benzothiazepine binding site for M2, M7 and M8. (Carosati E. et al. J. Med Chem. 2006, 49; 5206). In agreement with this findings, the relative order of increased rates of contraction and relaxation at lower concentrations s(≤10-6M) in unpaced hearts was M7>M2>M8>P1. Similar increases in Ca2+ transient were observed in cardiomyocytes. Diltiazem showed negative inotropic effects whereas 5b had no significant effect. Diltiazem blocks Ca2+current in a use-dependent manner and facilitates the channel by accelerating the inactivation and decelerating the recovery from inactivation. In contrast to diltiazem, the new analogs had no pronounced use-dependence. Application of 100 μM M8, M2 showed ~ 10% tonic block; in addition, M8, M2 and P1 shifted the steady state inactivation in hyperpolarized direction and the current inactivation time was significantly decreased compared with control (219.6 ± 11.5 ms, 226 ± 14.5 vs. 269 ± 12.9 vs. 199.28 ± 8.19 ms). Contrary to diltiazem, the recovery from the block by M8 and M2 was comparable to control. Only P1 showed a significantly decrease of the time for the recovery from inactivation. All of the compounds displayed the same sensitivity on the Ca2+ channel rabbit lung α1 except P1. Taken together, these findings suggest that M8, M2 and P1 might directly decrease the binding affinity or allow rapid dissociation from the benzothiazepine binding site.

Riccardo Lombardi nel socialismo italiano (1947-1964)

Il primo capitolo della tesi verte sull’ultimo anno di vita del Partito d’Azione, sulle modalità di partecipazione di Lombardi allo scontro elettorale del 1948 nelle liste del Fronte democratico popolare, e sul breve periodo di direzione ‘centrista’ del Psi a cavallo tra il 1948 e il 1949, quando Lombardi, appena entratovi, fu magna pars nel gruppo dirigente del partito. Il secondo capitolo abbraccia il periodo in cui Lombardi agì all’interno del Psi ‘morandiano’, o frontista: si è cercato di dare ragione sia dell’inserimento di Lombardi nelle logiche del frontismo socialista, sia della peculiarità di quell’inserimento negli ambiti privilegiati della politica economica e della politica estera. Oggetto del terzo capitolo è il ruolo giocato da Lombardi nella definizione delle linee guida dell’autonomismo socialista, un ruolo fattosi via via più pregnante a partire dal 1956, che ebbe la sua massima consacrazione col XXXIV Congresso del Psi, celebrato a Milano nel 1961: centrale in questo periodo la riflessione lombardiana sulle «riforme di struttura», un argomento che ci si è sforzati di inquadrare storicamente, sfuggendo dai luoghi comuni storiografici di cui spesso – con lodevoli eccezioni – è caduto vittima. Tali «riforme di struttura» Lombardi avrebbe voluto alla base dei governi di centro-sinistra. La tesi si chiude con un ultimo capitolo dedicato ad illustrare l’apporto di Lombardi al quarto Governo Fanfani e al primo Governo Moro, il ruolo da lui giocato nella loro nascita e il suo progressivo allontanamento da quell’esperimento che era stato, in gran parte, sua creatura.

Determinanti Sociali e Governance della Salute in Zambia: Politiche di Sviluppo ed Empowerment Partecipativo

A 30 anni dalla Dichiarazione di Alma Ata, l'Organizzazione Mondiale della Sanità, sia nei lavori della Commissione sui Determinanti Sociali della Salute che nel corso della sua 62^ Assemblea (2009) ha posto nuovamente la sua attenzione al tema dei determinanti sociali della salute e allo sviluppo di una sanità secondo un approccio "Primary Health Care", in cui la partecipazione ai processi decisionali è uno dei fattori che possono incidere sull'equità in salute tra e nelle nazioni. Dopo una presentazione dei principali elementi e concetti teorici di riferimento della tesi: Determinanti Sociali della Salute, partecipazione ed empowerment partecipativo (Cap. 1 e 2), il lavoro di tesi, a seguito dell'attività di ricerca di campo svolta in Zambia (Lusaka, Kitwe e Ndola) e presso EuropeAid (Bruxelles), si concentra sui processi di sviluppo e riforma del settore sanitario (Cap. 3), sulle politiche di cooperazione internazionale (Cap.4) e sull'azione (spesso sperimentale) della società civile in Zambia, considerando (Cap. 5): le principali criticità e limiti della/alla partecipazione, la presenza di strumenti e strategie specifiche di empowerment partecipativo, le politiche di decentramento e accountability, le buone prassi e proposte emergenti dalla società civile, le linee e i ruoli assunti dai donatori internazionali e dal Governo dello Zambia. Con questa tesi di dottorato si è voluto evidenziare e interpretare sia il dibattito recente rispetto alla partecipazione nel settore sanitario che i diversi e contraddittori gradi di attenzione alla partecipazione delle politiche di sviluppo del settore sanitario e l'emergere delle istanze e pratiche della società civile. Tutto questo incide su spazi e forme di partecipazione alla governance e ai processi decisionali nel settore sanitario, che influenzano a loro volta le politiche e condizioni di equità in salute. La metodologia adottata è stata di tipo qualitativo articolata in osservazione, interviste, analisi bibliografica e documentale.

Implicazioni teoriche e sperimentali della sincronizzazione assoluta nella teoria della relatività speciale

Sono indagate le implicazioni teoriche e sperimentali derivanti dall'assunzione, nella teoria della relatività speciale, di un criterio di sincronizzazione (detta assoluta) diverso da quello standard. La scelta della sincronizzazione assoluta è giustificata da alcune considerazioni di carattere epistemologico sullo status di fenomeni quali la contrazione delle lunghezze e la dilatazione del tempo. Oltre che a fornire una diversa interpretazione, la sincronizzazione assoluta rappresenta una estensione del campo di applicazione della relatività speciale in quanto può essere attuata anche in sistemi di riferimento accelerati. Questa estensione consente di trattare in maniera unitaria i fenomeni sia in sistemi di riferimento inerziali che accelerati. L'introduzione della sincronizzazione assoluta implica una modifica delle trasformazioni di Lorentz. Una caratteristica di queste nuove trasformazioni (dette inerziali) è che la trasformazione del tempo è indipendente dalle coordinate spaziali. Le trasformazioni inerziali sono ottenute nel caso generale tra due sistemi di riferimento aventi velocità (assolute) u1 e u2 comunque orientate. Viene mostrato che le trasformazioni inerziali possono formare un gruppo pur di prendere in considerazione anche riferimenti non fisicamente realizzabili perché superluminali. È analizzato il moto rigido secondo Born di un corpo esteso considerando la sincronizzazione assoluta. Sulla base delle trasformazioni inerziali si derivano le trasformazioni per i campi elettromagnetici e le equazioni di questi campi (che sostituiscono le equazioni di Maxwell). Si mostra che queste equazioni contengono soluzioni in assenza di cariche che si propagano nello spazio come onde generalmente anisotrope in accordo con quanto previsto dalle trasformazioni inerziali. L'applicazione di questa teoria elettromagnetica a sistemi accelerati mostra l'esistenza di fenomeni mai osservati che, pur non essendo in contraddizione con la relatività standard, ne forzano l'interpretazione. Viene proposto e descritto un esperimento in cui uno di questi fenomeni è misurabile.

Impact of gentrification processes in rural landscapes: a methodology for landscape assessment towards sustainable rural development

With an increasing demand for rural resources and land, new challenges are approaching affecting and restructuring the European countryside. While creating opportunities for rural living, it has also opened a discussion on rural gentrification risks. The concept of rural gentrification encircles the influx of new residents leading to an economic upgrade of an area making it unaffordable for local inhabitants to stay in. Rural gentrification occurs in areas perceived as attractive. Paradoxically, in-migrants re-shape their surrounding landscape. Rural gentrification may not only cause displacement of people but also landscape values. Thus, this research aims to understand the twofold role of landscape in rural gentrification theory: as a possible driver to attract residents and as a product shaped by its residents. To understand the potential gentrifiers’ decision process, this research has provided a collection of drivers behind in-migration. Moreover, essential indicators of rural gentrification have been collected from previous studies. Yet, the available indicators do not contain measures to understand related landscape changes. To fill this gap, after analysing established landscape assessment methodologies, evaluating the relevance for assessing gentrification, a new Landscape Assessment approach is proposed. This method introduces a novel approach to capture landscape change caused by gentrification through a historical depth. The measures to study gentrification was applied on Gotland, Sweden. The study showed a population stagnating while the number of properties increased, and housing prices raised. These factors are not indicating positive growth but risks of gentrification. Then, the research applied the proposed Landscape Assessment method for areas exposed to gentrification. Results suggest that landscape change takes place on a local scale and could over time endanger key characteristics. The methodology contributes to a discussion on grasping nuances within the rural context. It has also proven useful for indicating accumulative changes, which is necessary in managing landscape values.

“Puta”, “travesti” e “brasiliana”: processos interseccionais de tradução e criminalização entre Brasil e Itália

Esta tese se debruça nas (im)possibilidades de tradução terminológica para demonstrar uma incomunicabilidade entre o contexto brasileiro e italiano, em termos de trabalho sexual e políticas travestis. Proponho uma análise etnográfica dos usos dos termos, efetivada pela pessoa antropóloga também corporificada e marcada contextualmente. Apresento como nos dois contextos há uma aproximação entre as noções “puta” e “travesti” que se materializa em processos interseccionais de criminalização. Demonstro como no contexto brasileiro mais do que termos, envolvem disputas, agenciamentos e vivências corporificadas que refletem ativismos protagonizados por pessoas diretamente engajadas na transformação política dessas nomenclaturas – movimentações intransponíveis para o contexto italiano. Ao mesmo tempo, “brasiliana” ativa um imaginário italiano local que enquadra a prostituição e vivências trans majoritariamente como um problema migratório, para o qual se mobilizam ostensivos recursos e financiamentos que ganham forma no combate à “tratta” / tráfico de pessoas” – todo um aparato de difícil tradução para o contexto brasileiro. Dessa forma, partindo dos termos locais mobilizados nos dois contextos, penso nos elementos culturais naturalizados e em seu diálogo transcultural. Os processos de tradução são, desse modo, epistemológicos e necessariamente políticos, uma vez que estão situados em uma geopolítica marcadamente desigual. Afirmo, portanto, que as (im)possibilidades de tradução cultural se materializam em ativismos, políticas institucionais e normativas legais que ativam diversas formas de criminalizar possibilidades de existência, criação de redes de afeto e de potência política em trânsito.
