Le partecipazioni azionarie degli enti locali tra dismissione ed esigenze di governo dei servizi pubblici

La ricerca indaga le relazioni che si sono instaurate nel corso degli anni tra il principio di legalità, inteso nella sua declinazione di principio di funzionalizzazione, e principio di concorrenza nell’ambito delle società per la gestione dei servizi pubblici locali. Più precisamente, lo scopo del lavoro è valutare le evoluzioni di tale rapporto, dal momento in cui gli enti locali sono stati ufficialmente autorizzati a costituire società per la gestione dei servizi pubblici locali nel 1990. Lo stimolo a sviluppare queste considerazioni trova la sua ragione nelle pressioni provenienti dalle istituzioni europee, che hanno gradualmente imposto una qualificazione prettamente economica ai servizi a favore della collettività, ritenuti un ambito in cui possa naturalmente imporsi una competizione economica tra operatori economici, indipendentemente dalla loro natura giuridica. Il problema del vincolo funzionale nella partecipazione in società degli enti locali è certamente l’oggetto principale del lavoro. Tuttavia, la questione non può essere analizzata separatamente dalle politiche di dismissione promosse dal legislatore nell’ultimo decennio. L’obiettivo principale delle riforme avviate è stato quello di frenare la proliferazione di società costituite dagli enti locali, così da garantire sia un risparmio di risorse pubbliche sia una maggiore facilità per gli imprenditori privati ad affacciarsi su mercati tradizionalmente appannaggio delle amministrazioni. Stona però con le intenzioni il fatto che gli obblighi ex lege di cessione delle partecipazioni azionarie detenute dagli enti locali non siano stati generalmente imposti per le società di gestione dei servizi pubblici (resi in favore della collettività), bensì per quelle che svolgono servizi strumentali (in favore dell’amministrazione stessa). La scelta appare contraddittoria, in quanto il distacco tra vincolo funzionale e partecipazione degli enti locali nella compagine societaria si ravvisa in particolar modo nel primo dei due moduli menzionati. Si assiste dunque ad una frammentazione del principio di legalità.

Cultura materiale ed espansione di Roma: Il caso dell'Ager Gallicus

Lo scritto ha l’obiettivo di definire dinamiche e cronologie di quel complesso processo espansionistico che portò Roma alla conquista dei territori dell’Ager Gallicus, partendo dall’analisi dettagliata della cultura materiale e dei rispettivi contesti di provenienza emersi dalle recenti indagini archeologiche realizzate dal Dipartimento di Storia Culture Civiltà dell’Università degli Studi di Bologna nella città di Senigallia. In armonia con quanto testimoniato dalle sequenze stratigrafiche documentate, si delineano quattro principali fasi di vita dell’abitato: la prima preromana, la seconda riferibile alla prima fase di romanizzazione del sito, la terza inerente allo sviluppo dell’insediamento con la fondazione della colonia romana e l’ultima riferibile all’età repubblicana. Emerge con chiarezza la presenza già dalla fine del IV-inizio III a.C., di un insediamento romano nel territorio della città, sviluppatosi con la fondazione di un’area sacra e la predisposizione di un’area produttiva. La scelta del sito di Sena Gallica fu strategica: un territorio idoneo allo sfruttamento agricolo e utile come testa di ponte per la conquista dei territori del Nord Italia. Inoltre, questo centro aveva già intrecciato rapporti commerciali con gli insediamenti costieri adriatici e mediterranei. La presenza di ceramica di produzione locale, il rinvenimento di elementi distanziatori e le caratteristiche geomorfologiche del sito, fanno ipotizzare la presenza in loco di un’officina ceramica. Ciò risulta di grande importanza dato che tutte le attestazioni ceramiche prodotte localmente e rinvenute nel territorio, fino ad oggi sono attribuite alle officine di Aesis e Ariminum. Dunque Sena Gallica sarebbe stata un centro commerciale e produttivo. La precoce presenza di ceramica a Vernice Nera di tipo romano-laziale prodotte localmente prima dell’istituzione ufficiale della colonia, che permette di ipotizzare uno stanziamento di piccoli gruppi di Romani in territori appena conquistati ma non ancora colonizzati, attestata a Sena Gallica, trova riscontro anche in altri centri adriatici come Ariminum, Aesis, Pisaurum, Suasa e Cattolica.

The performativity of nonviolent protest in South Asia (1918 - 1948)

This study seeks to address a gap in the study of nonviolent action. The gap relates to the question of how nonviolence is performed, as opposed to the meaning or impact of nonviolent politics. The dissertation approaches the history of nonviolent protest in South Asia through the lens of performance studies. Such a shift allows for concepts such as performativity and theatricality to be tested in terms of their applicability and relevance to contemporary political and philosophical questions. It also allows for a different perspective on the historiography of nonviolent protest. Using concepts, modes of analysis and tropes of thinking from the emerging field of performance studies, the dissertation analyses two different cases of nonviolent protest, asking how politics is performatively constituted. The first two sections of this study set out the parameters of the key terms of the dissertation: nonviolence and performativity, by tracing their genealogies and legacies as terms. These histories are then located as an intersection in the founding of the nonviolent. The case studies at the analytical core of the dissertation are: fasting as a method in Gandhi's political arsenal, and the army of nonviolent soldiers in the North-West Frontier Province, known as the Khudai Khidmatgar. The study begins with an overview of current theorisations of nonviolence. The approach to the subject is through an investigation of commonly held misconceptions about nonviolent action, such as its supposed passivity, the absence of violence, its ineffectiveness and its spiritual basis. This section addresses the lacunae within existing theories of nonviolence and points to possible fertile spaces for further exploration. Section 3 offers an overview of the different shades of the concept of performativity, asking how it is used in various contexts and how these different nuances can be viewed in relation to each other. The dissertation explores how a theory of performativity may be correlated to the theorisation of nonviolence. The correlations are established in four boundary areas: action/inaction, violence/absence of violence, the actor/opponent and the body/spirit. These boundary areas allow for a theorising of nonviolent action as a performative process. The first case study is Gandhi's use of the fast as a method of nonviolent protest. Using a close reading of his own writings, speeches and letters, as well as a reading of responses to his fast in British newspapers and within India, the dissertation asks what made fasting into Gandhi's most favoured mode of protest and political action. The study reconstructs his unique praxis of the fast from a performative perspective, demonstrating how display and ostentation are vital to the political economy of the fast. It also unveils the cultural context and historical reservoir of body practices, which Gandhi drew from and adapted into 'weapons' of political action. The relationship of Gandhian nonviolence to the body forms a crucial part of the analysis. The second case study is the nonviolent army of the Pashtuns, Khudai Khidmatgar (KK), literally Servants of God. This anti-imperialist movement in the North-West Frontier Province of what is today the border between Pakistan and Afghanistan existed between 1929 and 1948. The movement adopted the organisational form of an army. It conducted protest activities against colonial rule, as well as social reform activities for the Pashtuns. This group was connected to the Congress party of Gandhi, but the dissertation argues that their conceptualisation and praxis of nonviolence emerged from a very different tradition and worldview. Following a brief introduction to the socio-political background of this Pashtun movement, the dissertation explores the activities that this nonviolent army engaged in, looking at their unique understanding of the militancy of an unarmed force, and their mode of combat and confrontation. Of particular interest to the analysis is the way the KK re-combined and mixed what appear to be contradictory ideologies and acts. In doing so, they reframed cultural and historical stereotypes of the Pashtuns as a martial race, juxtaposing the institutional form of the army with a nonviolent praxis based on Islamic principles and social reform. The example of the Khudai Khidmatgar is used to explore the idea that nonviolence is not the opposite of violent conflict, but in fact a dialectical engagement and response to violence. Section 5, in conclusion, returns to the boundary areas of nonviolence: action, violence, the opponent and the body, and re-visits these areas on a comparative note, bringing together elements from Gandhi's fasts and the practices of the KK. The similarities and differences in the two examples are assessed and contextualised in relation to the guiding question of this study, namely the question of the performativity of nonviolent action.

Fast kinase domain-containing protein 3 is a mitochondrial protein essential for cellular respiration

Fas-activated serine/threonine phosphoprotein (FAST) is the founding member of the FAST kinase domain-containing protein (FASTKD) family that includes FASTKD1-5. FAST is a sensor of mitochondrial stress that modulates protein translation to promote the survival of cells exposed to adverse conditions. Mutations in FASTKD2 have been linked to a mitochondrial encephalomyopathy that is associated with reduced cytochrome c oxidase activity, an essential component of the mitochondrial electron transport chain. We have confirmed the mitochondrial localization of FASTKD2 and shown that all FASTKD family members are found in mitochondria. Although human and mouse FASTKD1-5 genes are expressed ubiquitously, some of them are most abundantly expressed in mitochondria-enriched tissues. We have found that RNA interference-mediated knockdown of FASTKD3 severely blunts basal and stress-induced mitochondrial oxygen consumption without disrupting the assembly of respiratory chain complexes. Tandem affinity purification reveals that FASTKD3 interacts with components of mitochondrial respiratory and translation machineries. Our results introduce FASTKD3 as an essential component of mitochondrial respiration that may modulate energy balance in cells exposed to adverse conditions by functionally coupling mitochondrial protein synthesis to respiration.

Simultaneous stable isotope analysis of methane and nitrous oxide on ice core samples

Methane and nitrous oxide are important greenhouse gases which show a strong increase in atmospheric mixing ratios since pre-industrial time as well as large variations during past climate changes. The understanding of their biogeochemical cycles can be improved using stable isotope analysis. However, high-precision isotope measurements on air trapped in ice cores are challenging because of the high susceptibility to contamination and fractionation. Here, we present a dry extraction system for combined CH4 and N2O stable isotope analysis from ice core air, using an ice grating device. The system allows simultaneous analysis of δD(CH4) or δ13C(CH4), together with δ15N(N2O), δ18O(N2O) and δ15N(NO+ fragment) on a single ice core sample, using two isotope mass spectrometry systems. The optimum quantity of ice for analysis is about 600 g with typical "Holocene" mixing ratios for CH4 and N2O. In this case, the reproducibility (1σ ) is 2.1‰ for δD(CH4), 0.18‰ for δ13C(CH4), 0.51‰ for δ15N(N2O), 0.69‰ for δ18O(N2O) and 1.12‰ for δ15N(NO+ fragment). For smaller amounts of ice the standard deviation increases, particularly for N2O isotopologues. For both gases, small-scale intercalibrations using air and/or ice samples have been carried out in collaboration with other institutes that are currently involved in isotope measurements of ice core air. Significant differences are shown between the calibration scales, but those offsets are consistent and can therefore be corrected for.

Educating...for what?: Engagement and Citizenry

Higgins School of the Humanities/Difficult Dialogues: Video Recording from 11/3/2011 event featuring Tom Hayden and Bob Ross "Engagement and Citizenry" Event Description: During their undergraduate years, students participate in a community that is a microcosm of society, and have the opportunity to learn about what it means to be a member of a society—a citizen—while they live it. How do we as educators (and humanists) best support and model this process? Where in our pedagogy can we enhance and develop the qualities of skillful empathy, effective analysis and motivated responsibility that good citizenship demands? Our guest for a conversation on engagement and citizenry is long-time activist Tom Hayden, who was the primary author of the Port Huron Statement of Students for a Democratic Society, which became known for its advocacy of “participatory democracy”. He is joined in conversation by Professor Bob Ross of Clark University, who participated with Hayden in the founding of SDS.

Displaced premolars in panoramic radiography: fact or fallacy?

OBJECTIVE: To test the null hypothesis that there is no difference between premolar position visualized on panoramic radiographs (PRs) and lateral headfilms (LHs). MATERIALS AND METHODS: The prevalence of differences in the direction of crown angulation between PR and LH was assessed. Furthermore, brass wire markers with different sagittal and transverse angulations were placed in a dry skull. With the markers in place, LHs and PRs were taken. RESULTS: A difference in the direction of crown angulation of unerupted second premolars between PR and LH occurred in 19.5% of patients. The reason for the angulation differences is a buccolingual orientation of the tooth, which appears as a mesiodistal angulation on the PR. CONCLUSION: The null hypothesis was rejected since in one-fifth of the patients premolar projection differs between the panoramic radiograph and the lateral headfilm.

Experimental investigation of regular fluids and nanofluids during flow boiling in a single microchannel at different heat fluxes and mass fluxes

The dissipation of high heat flux from integrated circuit chips and the maintenance of acceptable junction temperatures in high powered electronics require advanced cooling technologies. One such technology is two-phase cooling in microchannels under confined flow boiling conditions. In macroscale flow boiling bubbles will nucleate on the channel walls, grow, and depart from the surface. In microscale flow boiling bubbles can fill the channel diameter before the liquid drag force has a chance to sweep them off the channel wall. As a confined bubble elongates in a microchannel, it traps thin liquid films between the heated wall and the vapor core that are subject to large temperature gradients. The thin films evaporate rapidly, sometimes faster than the incoming mass flux can replenish bulk fluid in the microchannel. When the local vapor pressure spike exceeds the inlet pressure, it forces the upstream interface to travel back into the inlet plenum and create flow boiling instabilities. Flow boiling instabilities reduce the temperature at which critical heat flux occurs and create channel dryout. Dryout causes high surface temperatures that can destroy the electronic circuits that use two-phase micro heat exchangers for cooling. Flow boiling instability is characterized by periodic oscillation of flow regimes which induce oscillations in fluid temperature, wall temperatures, pressure drop, and mass flux. When nanofluids are used in flow boiling, the nanoparticles become deposited on the heated surface and change its thermal conductivity, roughness, capillarity, wettability, and nucleation site density. It also affects heat transfer by changing bubble departure diameter, bubble departure frequency, and the evaporation of the micro and macrolayer beneath the growing bubbles. Flow boiling was investigated in this study using degassed, deionized water, and 0.001 vol% aluminum oxide nanofluids in a single rectangular brass microchannel with a hydraulic diameter of 229 µm for one inlet fluid temperature of 63°C and two constant flow rates of 0.41 ml/min and 0.82 ml/min. The power input was adjusted for two average surface temperatures of 103°C and 119°C at each flow rate. High speed images were taken periodically for water and nanofluid flow boiling after durations of 25, 75, and 125 minutes from the start of flow. The change in regime timing revealed the effect of nanoparticle suspension and deposition on the Onset of Nucelate Boiling (ONB) and the Onset of Bubble Elongation (OBE). Cycle duration and bubble frequencies are reported for different nanofluid flow boiling durations. The addition of nanoparticles was found to stabilize bubble nucleation and growth and limit the recession rate of the upstream and downstream interfaces, mitigating the spreading of dry spots and elongating the thin film regions to increase thin film evaporation.

Effect of Impurities upon Current Efficiency in the Electrolysis of Zinc Sulphate Solution

There are many elements which are detrimental to the current efficiency in the electrolysis of zinc sulphate solution. Fortunately the majority of these elements are easily removed in the purification process and cause no further trouble. The elements that are likely to cause trouble in ordinary plant operations are antimony, arsenic, cobalt, nickel, manganese and germanium. The following tests were made to determine the mutual effect on the current efficiency when several of the impurities were present in the electrolyte.

Electrolytic Recovery of Copper and Zinc from Brasses

Reclaimed metals, or secondary metals, are becoming of great im­portance in the metal industries of the world. Secondary metals are an important factor in production. The increase in the secondary production of copper is due to many factors. One of these may be its permenance, that is, the metal does not corrode very readily. Another reason for increase in production is the high price paid for it.

Executive Reorganization: Building a State Government That Worked for People -- Tom Harrison, Diana Dowling & Sheena Wilson “In the Crucible of Change”

One of the primary accomplishments of Governor Forrest Anderson in 1969-71 was the reorganization of the Executive Branch of Montana government, something that had been attempted six different times between 1919 and 1962 as state government had grown from twenty agencies to almost 200 uncontrolled boards, bureaus and commissions. The chaotic structure of the executive branch disempowered governors of both parties and empowered the private corporations and organizations that were the power structure of Montana. With remarkable political acumen, Governor Anderson figured out how to get that near impossible job done. Central to his efforts was the creation of an Executive Reorganization Commission, including eight legislators and the Governor, the adoption of a Constitutional Amendment that limited the executive branch to no more than twenty departments under the Governor, and the timely completion of a massive research effort to delineate the actual structure of the twenty departments. That story is told in this episode by three major players in the effort, all involved directly with the Executive Reorganization Commission: Tom Harrison, Diana Dowling and Sheena Wilson. Their recollections reflect an insider’s perspective of this significant accomplishment that helped change Montana “In the Crucible of Change.” Tom Harrison is a former Republican State Representative and State Senator from Helena, who was a member of the Executive Reorganization Commission. As Majority Leader in the Montana House of Representatives in 1971, he was the primary sponsor of the House’s executive reorganization bill and helped shepherd the Senate’s version to passage. Harrison was the Republican candidate for Attorney General in 1976 after which he practiced private law for 3 more decades. He served in the Montana Army National Guard for almost 34 years, rising to the rank of Colonel in the position of Judge Advocate General. He was a founding Director of Federal Defenders of Montana (legal representation for indigents accused within the Federal Judicial System); appointed Chairman of the original Montana State Fund (workers' compensation insurance) by Gov. Stephens; served as President of the Montana Trial Lawyers Association, Helena Kiwanis Club and St. Peter's Community Hospital Foundation, as well as Chairman and Director of AAA MountainWest; and was a founder, first Chairman and Director of the Valley Bank of Helena for over 25 years. Diana Dowling was an attorney for the Executive Reorganization Commission and helped draft the legislation that was passed. She also worked for Governor Forrest Anderson and for the 1972 Constitutional Convention where she prepared and directed publication of official explanation of the new Constitution that was mailed to all Montana voters. Diana was Executive Director of the Montana Bar Association and for 20 years held various legal positions with the Montana Legislative Council. For 12 years she was a commissioner on the National Conference of Commissioners on Uniform State Laws and for 7 years was a member of Montana State Board of Bar Examiners. Diana was the first director of the Montana Lottery, an adjunct professor at both Carroll College and the UM Law School, and an administrative officer for Falcon Press Publishing Co. Diana is currently - and intends to continue being - a perpetual college student. Sheena Wilson came fresh out of the University of Montana to become a Research Assistant for the Executive Reorganization Commission. Later she worked for seven years as a field representative in Idaho and Montana for the Mountain Plains Family Education Program, for thirteen years with Congressman Pat Williams as Executive Assistant in Washington and Field Assistant here in Montana, owned and managed a Helena restaurant for seven years, worked as Executive Assistant for State Auditor John Morrison and was Deputy Chief of Staff for Governor Brian Schweitzer his full 8 years in the Governorship. Though currently “retired”, Sheena serves on the Montana Board of Investments, the Public Employees Retirement Board and the Capitol Complex Advisory Council and is a partner in a dry-land wheat farm in Teton County that was homesteaded by her great uncle.

Is differentiation of frequently encountered foreign bodies in corpses possible by Hounsfield density measurement?

The radiological determination of foreign objects in corpses can be difficult if they are fragmented or deformed. With multislice computed tomography, radiodensities--referred to as Hounsfield units (HU)--can be measured. We examined the possibility of differentiating 21 frequently occurring foreign bodies, such as metals, rocks, and different manmade materials by virtue of their HU values. Gold, steel, and brass showed mean HU values of 30671-30710 (upper measurable limit), mean HU values for steel, silver, copper, and limestone were 20346, 16949, 14033, and 2765, respectively. The group consisting of objects, such as aluminum, tarmac, car front-window glass, and other rocks, displayed mean HU values of 2329-2131 HU. The mean HU value of bottle glass and car side-window glass was 2088, whereas windowpane glass was 493. HU value determination may therefore help in preautopsy differentiation between case-relevant and irrelevant foreign bodies and thus be useful for autopsy planning and extraction of the objects in question.
