S. Eliot’s "The Waste Land" Bonaventure Muzigirwa MungangaStudies in Stylistics in the past few decades have branched out to include the most diverse contexts of language production and have drawn on a vast array of methodologies, leading to what has been acknowledged as its interdisciplinary turn. As occurred in other paradigms, the approach shifted from regarding language as a synchronic, static, and homogenous system to a diachronic, social, and dynamic entity. It is this interest in the diachronic dimension that eventually gave rise to studies into Historical Stylistics, or rather, a New Historical Stylistics, and, as a sister discipline, into Historical Pragmatics. Both fields of study have adapted methods and devices developed in Stylistics and Pragmatics to work on texts from the past (literary and otherwise) and on language use and variation in past contexts, in order to understand how meaning is made and supply new materials and evidence to linguists, historical linguists, and language historians. In the wake of such innovations in the approach to stylistic studies, the present issue of Status Quaestionis aims to take a closer and updated look to a select group of texts, literary and non-literary. The diversity of approaches that inform the essays is intended to reflect the varied critical scenario that marks contemporary stylistic studies and the different trends in the approach to reading texts here represented will also bring to light a number of key questions regarding the methods and outcomes of such readings or analysis
Role of Facets and Morphologies of Different Bismuth-Based Materials for CO2 Reduction to Fuels
No full textCarbon dioxide (CO2) emission has been a global concern over the past few decades due to the increase in the demand of energy, a major source of which is fossil fuels. To mitigate the emission issues, as well as to find a solution for the energy needs, an ample load of research has been carried out over the past few years in CO2 reduction by catalysis. Bismuth, being an active catalyst both photocatalytically and electrocatalytically, is an interesting material that can be formed into oxides, sulphides, oxyhalides, etc. Numerous works have been published based on bismuth-based materials as active catalysts for the reduction of CO2. However, a proper understanding of the behavior of the active facets and the dependence of morphology of the different bismuth-based catalysts is an interesting notion. In this review, various bismuth-based materials will be discussed regarding their activity and charge transfer properties, based on the active facets present in them. With regard to the available literature, a summarization, including photocatalysis, electrocatalysis as well as photoelectrocatalysis, will be detailed, considering various materials with different facets and morphologies. Product selectivity, varying on morphological difference, will also be realized photoelectrochemically

No full textWaste management performances beyond the Italian North-South Divide: Spatial Analyses of Geographical, Economic and Institutional Dimensions
No full textMany advanced countries have been experiencing waste crises, namely a failure to properly collect and separate urban waste, difficulties regarding both the management landfill sites close to or beyond their full capacity, and the collocation of landfills and incinerators in the territory. These crises appear to be primarily driven by policy failures that include delays in introducing more economically-oriented instruments and a lack of new and diversified tools in waste management and disposal facilities. Italy has been and is a premier case study, with major crises appearing in its less-developed South. Though the North-South divide is a core part of the history of waste and other ‘convergence failures’ and belongs to a typical economic development analysis – it has received attention within ‘Waste Kuznets curves’ literature - we believe nevertheless that other forces and dynamics play an important role. For instance, the process of policy decentralisation that has characterised many good public provisions, which delegates competencies to regions and provinces, is a key aspect behind waste management performance. Within larger autonomous spaces, different provinces can achieve different performances, either by imitating or differentiating themselves from neighbouring agents.
The main research question is to assess whether it is truly just a North-South divide that largely explains the heterogeneous waste management and disposal performances inside Italy, or whether, as we believe, a different type of geo-clustering becomes apparent, which depends more on the quality of waste policy and idiosyncratic socio-economic factors. On the basis of a 2000-2008 dataset that covers 103 provinces over a wide range of information on waste management, socio-economic, structural and policy features, we aim at identifying ‘economic and institutional waste models’ by grouping the performances of provinces over time and space. The dynamic evolution of clusters allows for an analysis of how the system performance has evolved, as well as what weaknesses and strengths in terms of ‘waste management/policy models’ may exist

Recent advances in transition metal sulfide-based electrocatalysts and photocatalysts for nitrogen fixation
No full textAmmonia production through electrocatalytic and photocatalytic N2 fixation approaches has attracted a huge interest as a sustainable and clean route owing to the use of renewable energy to drive the processes. However, these approaches do not fulfil the industrial requirement because of the poor catalytic activity and efficiency of the catalysts. Therefore, rationally designed and highly efficient catalysts are urgently needed. Transition metal sulfide-based catalysts have gained great research interest as promising materials to catalyze artificial ammonia synthesis due to their structural similarity to the active site of the natural nitrogenase. This review gives some insights into the recent progress on the developments of transition metal sulfide-based electrocatalysts and photocatalysts for nitrogen fixation to ammonia under ambient conditions. A prospect on the future develop-ment on the rational design of efficient metal sulfide-based catalysts for artificial N2 fixation is also discussed
Ruolo del Sistema Immunitario e dei Progenitori Endoteliali nella Patogenesi della Sclerodermia Localizzata Giovanile
No full textJuvenile Localized Scleroderma (JLS) is a chronic inflammatory disease. Abnormalities in the Immune System (IS) and in the microvasculature are important. Forty two JLS patients and 39 healthy controls entered the study. They were analyzed at the beginning and then randomized into two subgroups, one treated with MTX and the other one treated with placebo. Lymphocyte distribution and NK cell receptor (NKR) expression was explored and EPCs were quantifyed in the peripheral blood of the patients by flow cytometric analysis and the inflammatory infiltrate in the skin lesions was evaluated by immunoistochemical analysis. JLS patients showed an enhanced expression of the NK cell activity, a decreased number of circulating EPCs and an infiltrate rich in T lymphocyte in the affected skin. MTX affected the disease locally, at skin level, by a consistent reduction of the inflammatory infiltrate while did not influence the immunological pattern in the peripheral blood.La Sclerodermia Localizzata Giovanile è una malattia infiammatoria cronica. Sono state riscontrate anormalità del Sistema Immunitario e della microvascolatura. In questo studio sono stati arruolati 42 pazienti con diagnosi di JLS e 39 soggetti sani come controlli. I pazienti sono sati analizzati al momento dell'arruolamento e in seguito sono stati randomizzati in due gruppi, uno trattato con MTX e uno trattato con placebo. E' stata analizzata la distribuzione delle sottopopolazioni linfocitarie, l'espressione dei recettori delle cellule NK e il numero delle EPC nel sague periferico dei pazienti attraverso analisi citofluorimetrica; inoltre è stato caratterizzato l'infiltrato infiammatorio presente nelle lesioni cutanee mediante analisi immunoistochimica. I pazienti affetti da JLS studiati hanno mostrato un aumento della citotossicità delle cellule NK e una deplezione del numero delle EPC nel sangue periferico ed un infiltrato ricco di linfociti T a livello delle lesioni cutanee. Il MTX sembrava indurre una remissione dell'infiltrato infiammatorio cutaneo, ma non sembrava avere alcun effetto sull'assetto immunologico presente nel sangue periferico
Targeted inactivation of the COP9 signalosome impairs multiple stages of T cell development
No full textGenetic programs promoting cell cycle progression, DNA repair, and survival are coordinately induced in developing T cells and require rapid turnover of effector molecules. As the COP9 signalosome (CSN) has been placed at the crossroads of these programs in lower organisms, we addressed its role by conditionally deleting CSN5/JAB1, its catalytic subunit, in developing thymocytes. CSN5/JAB1(del/del) thymocytes show defective S phase progression and massive apoptosis at the double-negative (DN)4-double-positive (DP) transition stage, which is paralleled by altered turnover of selected CSN-controlled substrates, including p53,I kappa B-alpha, and beta-catenin. Combined dysregulation of the p53 and NF-kappa B pathways affects thymocyte survival by altering the mRNA and protein levels of selected Bcl-2 family members. Genetic complementation analysis performed on p53(-/-), Bcl-xL/Bcl-2A1, or T cell receptor transgenic backgrounds indicates that CSN5/JAB1 acts at distinct developmental stages to coordinate proliferation, survival, and positive selection of thymocytes by controlling the induction of defined genetic programs acting downstream of CSN-regulated transcription factors.
