Il disegno a pastello in Italia nel XVI secolo: un problema critico

Il tema della ricerca sono i caratteri della grafica a pastello in area italiana nel XVI secolo. Il lavoro è articolato in tre parti. Il primo capitolo analizza l’uso e il significato del termine “pastello” nelle fonti Cinque-Seicentesche. Il secondo capitolo ricostruisce il dibattito critico multidisciplinare sull’argomento. Se da una parte l’attenzione riservata al pastello da specialisti di diversi settori ha portato a una feconda varietà di punti di vista, dall’altro ha avuto come risultato una serie di ricostruzioni frammentarie. All’interno del dibattito sulla tecnica è stato possibile distinguere posizioni differenziate, in parte conseguenza dei diversi approcci e specializzazioni, ed enucleare alcuni nodi critici meritevoli di approfondimento. In primo luogo è possibile distinguere varie opinioni sulla fondamentale questione della natura e dei criteri di identificazione del medium, in particolare per i disegni risalenti al XVI secolo ovvero alla fase “embrionale” dell’utilizzo della tecnica. Si è proceduto poi, sulla base di queste premesse, all’analisi dei disegni del XVI secolo tradizionalmente ritenuti o recentemente proposti dalla storiografia come opere a pastello in ambito milanese, nelle aree settentrionali e centro-italiane. Successivamente è stato quindi studiato il ruolo della tecnica all’interno della grafica di Federico Barocci e Jacopo Bassano , i due artisti che si dedicano con maggiore intensità all’esplorazione delle possibilità del medium. Sono state infine considerate opere di artisti appartenenti alle generazioni successive (sempre entro il XVI secolo) che sperimentano l’uso dei pastelli policromi sul modello di Barocci e Bassano.

Propuesta de Instrumentos de Promoción Dd Inversión Directa en el Extranjero Enfocados en Encadenamientos Productivos

La Inversión Directa en el Exterior representa el proceso más grande hacia la internacionalización de las empresas después de las exportaciones. Tal proceso significa una mejora en la competitividad de las empresas, traducida en mayor penetración en el mercado internacional, acceso a mejores tecnologías, recursos naturales e investigación. Este proyecto de investigación pretende formular una propuesta de instrumentos o servicios de promoción de inversión directa en el exterior, enfocados en encadenamientos productivos. En un primer lugar, se establecerá el marco teórico bajo el cual se desarrollara el proyecto, mediante la recolección de información relevante en teorías de internacionalización y en la descripción de encadenamientos productivos y clúster. En segundo lugar, se presentara el entorno macroeconómico y la evolución de los flujos de inversión directa en el extranjero en Colombia y Latinoamérica. Y finalmente, se hará un estudio comparativo de los servicios prestados por las principales agencias de promoción de inversión, que servirá de base para la posterior formulación de la propuesta de instrumentos de promoción de inversión.

Noninvasive assessment of acute ureteral obstruction with diffusion-weighted MR imaging: a prospective study

PURPOSE: To prospectively assess the potential of noninvasive diffusion-weighted magnetic resonance (MR) imaging to depict changes in microperfusion and diffusion in patients with acute unilateral ureteral obstruction. MATERIALS AND METHODS: The local ethics committee approved the study protocol. Informed consent was obtained. Diffusion-weighted MR imaging was performed in 21 patients (two women, 19 men; mean age, 43 years +/- 10 [standard deviation]) with acute unilateral ureteral obstruction due to a calculus diagnosed at unenhanced computed tomography. A control group (one woman, 15 men; mean age, 44 years +/- 12) underwent the same MR protocol. Standard processing yielded an apparent diffusion coefficient (ADC) ADCT; the separation of microperfusion and diffusion contributions yielded the perfusion fraction FP and the pure diffusion coefficient ADCD. ADCT, ADCD, and FP were compared between obstructed and contralateral unobstructed kidneys and with control values. For statistical analysis, nonparametric rank tests were used. A P value of less than .05 was considered significant. RESULTS: No significant differences were observed between the ADCT of the medulla or cortex of the obstructed and unobstructed kidneys. Compared with control kidneys, only medullary ADCT was slightly increased in the obstructed kidney (P < .04). However, the ADCD in the medulla of the obstructed and unobstructed kidneys was significantly higher than that in control subjects (201 x 10(-5) mm2/sec +/- 16 and 199 x 10(-5) mm2/sec +/- 20 vs 189 x 10(-5) mm2/sec +/- 12; P < .008 and P < .03, respectively). FP of the cortex of the obstructed kidney was significantly lower than that in the unobstructed kidney (20.2% +/- 4.8 vs 24.0% +/- 5.8; P < .002); FP of the medulla was slightly lower in the obstructed kidney than in the unobstructed kidney (18.3% +/- 5.9 vs 20.7% +/- 6.4; P = .05). CONCLUSION: Diffusion-weighted MR imaging allows noninvasive detection of changes in renal perfusion and diffusion during acute unilateral ureteral obstruction, as exemplified in patients with a ureteral calculus.

Assessment of retail and wholesale market competition in the Illinois electric industry /

In this report, the Commission examines developments relevant to the competitiveness of the retail and wholesale markets. In the retail market, two key indicators of activity are examined: The first indicator is the rate of customer switching from bundled services to "delivery services." Customers taking delivery services are either purchasing power and energy from ARES or are purchasing power and energy from the host utility on an "unbundled" basis under the utility's delivery services tariffs. Currently, bundled power sales mainly consist of sales to customers under the Sec. 16-110 "Power Purchase Option" (PPO). The second indicator of retail activity presented in this report is the number of suppliers active in the State's nine service territories.

Incidencia de la gestión de Frontex y el gobierno italiano en la acentuación de la crisis humanitaria de la Isla de Lampedusa entre 2011 y 2015

El presente estudio de caso busca examinar la incidencia de las medidas migratorias de control fronterizo implementadas por el Frontex y el gobierno Italiano en las condiciones mínimas de supervivencia de los migrantes irregulares, económicos y solicitantes de asilo en la Isla de Lampedusa, en el periodo 2011-2015. De esta manera, se identifican las medidas migratorias de control fronterizo implementadas por Frontex y el gobierno Italiano. Se examina la situación de la seguridad humana en la crisis migratoria de la Isla, y se analiza la relación entre las medidas migratorias de control fronterizo y las condiciones mínimas de supervivencia de los migrantes. El resultado de la investigación permite plasmar, las consecuencias negativas que han tenido las medidas migratorias en cuanto a las condiciones mínimas de supervivencia, lo que ha desembocado en una crisis humanitaria.
