La storia agli storici
2012
Gli atti del seminario tenutosi nell’aula magna della Facoltà di Lettere e Filosofia nell’ormai lontano novembre 2000, che oggi si pubblicano, forse sarebbero scarsamente comprensibili senza l’ampia e articolata introduzione di Fabrizio D’Avenia, il quale, con una analisi paziente e molto ben documentata, è riuscito a ricostruire felicemente il contesto politico e storiografico in cui il dibattito di allora deve necessariamente collocarsi. Essa costituisce quindi una premessa indispensabile alla successiva lettura degli interventi. L’introduzione di D’Avenia, tuttavia, non si limita soltanto alla puntuale verifica storiografica delle diverse posizioni e alla corretta focalizzazione dei nodi…
La storia, gli storici
2012
Questo volumetto raccoglie gli atti di un dibattito svoltosi presso la Facoltà di Lettere e Filosofia di Palermo il 29 novembre 2000. Il tema della discussione, “la storia, gli storici”, riguardava i manuali di storia in uso nelle scuole superiori, con l’intervento non solo di professori universitari di storia, ma anche di docenti di alcuni licei palermitani, in un confronto – tanto interessante quanto raro – tra mondo universitario e mondo scolastico. La scelta del tema non era ovviamente casuale ma rispondeva a un’esigenza ben precisa: discutere il contenuto di due mozioni presentate rispettivamente presso il Consiglio regionale del Lazio e, pochi giorni dopo, presso l’Assemblea Regionale…
Advances in the endoscopic management of malignant biliary obstruction
2020
Biliary obstruction is common in pancreatobiliary malignancies and has a negative impact on the patient’s quality of life, postoperative complications, and survival rates. Particularly in the last decade, there has been enormous progress regarding the diagnostic and therapeutic options in patients with malignant biliary obstruction. Endoscopy has given a new insight in this direction and novel techniques have been developed for the better characterization and treatment of malignant strictures. We herein summarize the available data on the different endoscopic techniques, and clarify their role in the diagnosis and treatment of malignant biliary obstructive disease. Finally, we propose an al…
Past, present, and future of green product innovation
2021
Firms are under constant pressure from various governmental and nongovernmental agencies to switch from conventional environmentally polluting products to green product innovations (GPIs). However, the relevant research pertaining to GPI has been published in a diverse set of journals that vary in their scope and readership and, therefore, the scholarly contribution to the topic remains largely fragmented. This study has utilised a systematic literature review approach to examine the literary corpus on GPI to paint a holistic picture of its different aspects. The content and thematic analysis of 85 studies resulted in the extraction of seven key research themes: organisational capabilities,…
End Users’ Perspective of Performance Issues in Google Play Store Reviews
2022
The success of mobile applications is closely tied to their performance which shapes the user experience and satisfaction. Most users often delete mobile apps from their devices due to poor performance indicating a mobile app’s failure in the competitive market. This paper performs a quantitative and qualitative analysis and investigates performance-related issues in Google Play Store reviews. This study has been conducted on 368,704 reviews emphasizing more 1- and 2-star reviews distributed over 55 Android apps. Our research also reports a taxonomy of 8 distinct performance issues obtained using manual inspection. Our findings show that end-users recurrently raised Updation (69.11%), Respo…
Structural Motifs of Alkali Metal Superbases in Non‐coordinating Solvents
2020
Abstract Lochmann–Schlosser superbases (LSB) are a standard reagent in synthetic chemistry to achieve an exchange of a proton on an organic framework with an alkali metal cation, which in turn can be replaced by a wide range of electrophilic groups. In standard examples, the deprotonating reagent consists of an equimolar mixture of n‐butyllithium and potassium t‐butoxide. However, the nature of the reactive species could not be pinned down either for this composition or for similar mixtures with comparable high reactivity. Despite the poor solubility and the fierce reactivity, some insights into this mixture were achieved by some indirect results, comparison with chemically related systems,…
Review: Mass spectrometry of surfactant aggregates
2011
In contrast with the enormous amount of literature produced during many decades in the field of surfactant aggregation in liquid, liquid crystalline and solid phases, only a few investigations concerning surfactant self-assembling in the gas phase as charged aggregates have been carried out until now. This lack of interest is disappointing in view of the remarkable theoretical and practical importance of the inherent knowledge. The absence of surfactant–solvent interactions makes it easier to study the role of surfactant–surfactant forces in determining their peculiar self-assembling features as well as the ability of these assemblies to incorporate selected solubilizate molecules. Thus, th…
Clinical Behavior of Ceramic, Hybrid and Composite Onlays. A Systematic Review and Meta-Analysis
2020
A systematic review and meta-analysis was performed to analyze the survival of onlay restorations in the posterior region, their clinical behavior according to the material used (ceramic reinforced with lithium disilicate, conventional feldspathic ceramic or reinforced with leucite; hybrid materials and composite), possible complications, and the factors influencing restoration success. The systematic review was based on the preferred reporting items for systematic reviews and meta-analyses (PRISMA) statement, without publication date or language restrictions. An electronic search was made in the PubMed, Scopus, Embase, and Cochrane databases. After discarding duplicate publications and stu…
Clinical Behavior of Short Dental Implants: Systematic Review and Meta-Analysis
2020
Short implants are an increasingly common alternative to other surgical techniques in areas where bone availability is reduced. Despite the advantages they offer, a variety of biological repercussions have been described in the literature that can even lead to the loss of these. The aim of this systematic review and meta-analysis was to analyze the impact of the use of short implants on their survival and on peri-implant bone loss, evaluating the influence that length, diameter, and crown-to-implant ratio (C/I) have on these parameters. This systematic review was based on guidelines proposed by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). An electronic se…
Brief an Garlieb H. Merkel
1797
Ms. 930a, Nr. 5, Bl. 11r-14v Recke, Charlotte Elisabeth (Elisa) Constantia v. der. Brief an Garlieb H. Merkel, Pyrmont (?), d[en] 8. May 1797 Autora rokraksts / Autograph, vācu un franču val. / Deutsch und Französisch [8] lpp. / S. Attēlu numuri / Bildnummern: 930a-005-1 – 930a-005-8 Der Brief von Elisabeth von der Recke wurde wahrscheinlich in Pyrmont verfasst. Die Autorin bezieht sich auf einen Brief Merkels, auf den sie antwortet. Sie äußert ihre grundsätzliche Zustimmung zur Idee einer Befreiung der Bauern in Liv- und Kurland und kann als Besitzerin zweier Güter, die ihr von der Kaiserin Katharina II. übereignet wurden, als Adressatin von Merkels Forderungen, die er in „Die Letten“ form…
