Crisi alimentare, banditismo e mafia
2021
Il contributo ricostruisce la congiuntura post-bellica in Sicilia, dopo lo sbarco alleato del 10 luglio 1943. In particolare, il saggio si concentra sul nesso fra crisi sociale, alimentare e banditismo, ripercorrendo alcune delle tappe della "carriera" criminale di Salvatore Giuliano, sullo sfondo della ricomposizione sociale e politica della Sicilia e dell'Italia. In questo contesto di elevata conflittualità sociale e al contempo di democratizzazione e organizzazione del conflitto attraverso partiti e sindacati, viene ricollocata la tragica vicenda della strage di Portella della Ginestra, del 1° maggio 1947.

Suitability of MMGBSA for the selection of correct ligand binding modes from docking results
2019
The estimation of the correct binding mode and affinity of a ligand into a target protein using computational methods is challenging. However, docking can introduce poses from which the correct binding mode could be identified using other methods. Here, we analyzed the reliability of binding energy estimation using the molecular mechanics‐generalized Born surface area (MMGBSA) method without and with energy minimization to identify the likely ligand binding modes within docking results. MMGBSA workflow (a) outperformed docking in recognizing the correct binding modes of androgen receptor ligands and (b) improved the correlation coefficient of computational and experimental results of rescor…

Controlling Oxidative Addition and Reductive Elimination at Tin(I) via Hemi-Lability.
2021
We report on the synthesis of a distannyne supported by a pincer ligand bearing pendant amine donors that is capable of reversibly activating E–H bonds at one or both of the tin centres through dissociation of the hemi-labile N–Sn donor/acceptor interactions. This chemistry can be exploited to sequentially (and reversibly) assemble mixed-valence chains of tin atoms of the type ArSn{Sn(Ar)H} n SnAr ( n = 1, 2). The experimentally observed (decreasing) propensity towards chain growth with increasing chain length can be rationalized both thermodynamically and kinetically by the electron-withdrawing properties of the –Sn(Ar)H– backbone units generated via oxidative addition. peerReviewed
Oxygen Transfer from Trimethylamine N-oxide to CuI Complexes Supported by Pentanitrogen Ligands
2020
[N,N-bis(1-methyl-2-benzimidazolyl)methyl-N-(bis-2-pyridylmethyl)amine] ( L 1 ) and [N,N-bis(2-quinolylmethyl)-N-bis(2-pyridyl)methylamine] ( L 2 ) were employed to prepare Cu II and Cu I complexes for spectroscopic and structural characterization. [ L 1 Cu II (H 2 O)](NO 3 ) 2 and [ L 2 Cu II (NO 3 )]NO 3 have Jahn-Teller distorted octahedral geometries, and give rise to isotropic EPR spectra in frozen solution. [ L 1 Cu I (CH 3 CN)]OTf and [ L 2 Cu I (CH 3 CN)]OTf have distorted trigonal bipyramidal and tetrahedral solid-state structures, respectively. The N-donors display labile behavior in solution, based on variable-temperature 1 H NMR studies. Addition of trimethylamine N-oxide (Me …
Noncovalent axial I∙∙∙Pt∙∙∙I interactions in platinum(II) complexes strengthen in the excited state
2021
Abstract Coordination compounds of platinum(II) participate in various noncovalent axial interactions involving metal center. Weakly bound axial ligands can be electrophilic or nucleophilic; however, interactions with nucleophiles are compromised by electron density clashing. Consequently, simultaneous axial interaction of platinum(II) with two nucleophilic ligands is almost unprecedented. Herein, we report structural and computational study of a platinum(II) complex possessing such intramolecular noncovalent I⋅⋅⋅Pt⋅⋅⋅I interactions. Structural analysis indicates that the two iodine atoms approach the platinum(II) center in a “side‐on” fashion and act as nucleophilic ligands. According to c…
Iodine(I) and Silver(I) Complexes Incorporating 3-Substituted Pyridines
2023
Building upon the first report of a 3-acetaminopyridine-based iodine(I) complex (1b) and its unexpected reactivity toward tBuOMe, several new 3-substituted iodine(I) complexes (2b–5b) have been synthesized. The iodine(I) complexes were synthesized from their analogous silver(I) complexes (2a–5a) via a silver(I) to iodine(I) cation exchange reaction, incorporating functionally related substituents as 3-acetaminopyridine in 1b; 3-acetylpyridine (3-Acpy; 2), 3-aminopyridine (3-NH2py; 3), and 3-dimethylaminopyridine (3-NMe2py; 4), as well as the strongly electron-withdrawing 3-cyanopyridine (3-CNpy; 5), to probe the possible limitations of iodine(I) complex formation. The individual properties …
Ten facts about content marketing
2018
Content marketing is facing what most trendy topics face: it is more publicly discussed than it is truly understood. Thus far content production has relied on case-specific, individual reports, and the final outcomes of content have provided surprises, both positive or negative. In hindsight it is easy to explain content success and failure, but academic studies on the logic of content creation and content life cycle have been missing. The ambitious goal of this research, Opening the Black Box of Content Marketing, funded by Business Finland, has been to systematically open up the logic of content marketing. In our project, we asked what constitutes content related expectations, how are con…
Communicating Corporate Social Responsibility – Brand management
2007
Corporate action is subject to more scrutiny than ever. An attempt to legitimize the corporate role is seen in corporate social responsibility as a part of a triple bottom line framework. Corporate principles are communicated in various forms to a wide set of stakeholders. Ideally, what is communicated in terms of principles is also seen in business practice. In cases where the principles and actions differ, the platform for creating a brand territory is limited. The communication platform is affected by, for example, corporate documents, actions and media perceptions. The studied cases, from the construction industry, illustrate how media portrays business conduct. It shows that the corpor…
