Between Criminal Gaze and Missing Memory: "Genet a Tangeri" by Magazzini Criminali
No full textWhen a leading Italian theatre group, Magazzini Criminali, staged the play "Genet a Tangeri" in a slaughterhouse in 1985, a scandal burst that had catastrophic consequences on the artists involved. After the immediate reconstruction by Ferdinando Taviani, this episode was cautiously silenced, leaving behind it a missing memory over the gap between the groups' expected response and the spectators' final reactions, between the careful construction of the event and its "criminal" consequent dismaltling. This paper recounts this process while presenting the different layers of interpretation and the various spectatorial stances it implied, which lead to further questions on the boundary between life and art
Group 12 metal complexes of mixed thia/aza and thia/oxa/aza macrocyclic ligands
No full textThe coordination behaviour of the macrocyclic ligands N-(2-pyridylmethyl)-[12]aneNS(2)O (L-1) and N-(2-pyr-idylmethyl)-[12]aneNS(3) (L2) ([12]aneNS(2)O = 1-aza-4,10-dithia-7-oxacyclododecane, [12]aneNS(3) = 1-aza4,7,10-trithia-cyclododecane) was studied in complexation reactions with ZnCl2, CdI2 and HgCl2. The NMR and mass spectra suggest the formation of the ionic species [LMX](2)[MX4] [M = Zn, X = Cl, L = L-1 (1), L-2 (2); M = Cd, X = I, L = L-1 (3), L-2 (4); M = Hg, X = Cl, L = L-1 (5), L-2 (6)]. The X-ray diffraction studies confirmed the formation of the new species 3-6, with [LMX](+) cations and [MX4](2-)& nbsp;anions, while for the zinc(II) complex 1 the determined structure corresponds to the hydrolysis product of formula [(LZn)-Zn-1](2)[ZnCl3](2)[Zn2Cl6]center dot & nbsp;2H(2)O (1h), with [(LZn)-Zn-1(H2O)](2+) cations and [ZnCl3(H2O)](-) and [Zn2Cl6](2-)& nbsp;anions. In all complexes the metal ion is hexacoordinated in cations, while in anions the metal is tetrahedrally surrounded by halido ligands
Evaluation of the Antioxidant Activity of Nigella sativa L. and Allium ursinum Extracts in a Cellular Model of Doxorubicin-Induced Cardiotoxicity
No full textNatural products black cumin—Nigella sativa (N. sativa) and wild garlic—Allium ursinum (AU) are known for their potential role in reducing cardiovascular risk factors, including antracycline chemotherapy. Therefore, this study investigates the effect of N. sativa and AU water and methanolic extracts in a cellular model of doxorubicin (doxo)-induced cardiotoxicity. The extracts were characterized using Ultraviolet-visible (UV-VIS) spectroscopy, Fourier-transform infrared (FT-IR) spectroscopy, Liquid Chromatography coupled with Mass Spectrometry (LC-MS) and Gas Chromatography coupled with Mass Spectrometry (GC-MS) techniques. Antioxidant activity was evaluated on H9c2 cells. Cytosolic and mitochondrial reactive oxygen species (ROS) release was evaluated using 2′,7′-dichlorofluorescin-diacetate (DHCF-DA) and mitochondria-targeted superoxide indicator (MitoSOX red), respectively. Mitochondrial membrane depolarization was evaluated by flow cytometry. LC-MS analysis identified 12 and 10 phenolic compounds in NSS and AU extracts, respectively, with flavonols as predominant compounds. FT-IR analysis identified the presence of carbohydrates, amino acids and lipids in both plants. GC-MS identified the sulfur compounds in the AU water extract. N. sativa seeds (NSS) methanolic extract had the highest antioxidant activity reducing both intracellular and mitochondrial ROS release. All extracts (excepting AU methanolic extract) preserved H9c2 cells viability. None of the investigated plants affected the mitochondrial membrane depolarization. N. sativa and AU are important sources of bioactive compounds with increased antioxidant activities, requiring different extraction solvents to obtain the pharmacological effects
The Use of Multi-Source Feedback as a Human Resource Management Tool
No full textThe article is devoted to the Multiple Source Assessment method as a process of Human Resource Management. Several aspects related to the definition of this method and others concerning its importance, purpose, application and feedback are presented. This method has been used for personal development at the organizational level, and then has begun to be directed to other purposes related of efficiency and performance. The method is considered revolutionary for human resources’ evaluation. It is increasingly used at an international level, with a growing prevalence. Recently, it has also begun to be used in the Romanian companies.multiple source assessment, human resource management, performance
“Socialism of sentiment:” Culture, progress and community in the early Romanian left 1870-1914
No full textMy dissertation questions the traditional assumption of the absence of an indigenous socialist tradition in Romania prior to the Soviet takeover in 1944 by exploring the cultural and intellectual history of early socialism between 1880 and 1914. Moving away from the unimpressive political and institutional history of Romanian socialism, I argue that in conditions of limited political space, socialism was refashioned in a powerful and attractive cultural orientation, particularly visible in the fields of literary criticism and the popularization of science. Using quantitative methods and examining periodicals, memoirs, correspondence, literary and scientific works, as well as archival sources, my study ascertains and documents the previously contested presence of a sizeable and cohesive socialist intellectual community. Prominent within this community was Constantin Dobrogeanu-Gherea, a Russian-born socialist theoretician and literary critic, who founded a deeply influential school of cultural criticism. Equally important for this community’s intellectual profile was a fascination with science which I explored along two axes: programs for the popularization of science and campaigns for public health and social hygiene. Both are indicative of socialist intellectuals’ deep sense of social mission and their practical appreciation for science as a vehicle for improving everyday life. Together, these cultural endeavors enhanced the visibility of the socialist movement and established its identity.
Socialism of Sentiment brings together four previously unconnected historical fields and bodies of scholarship: the history of political ideologies, literary history, history of science and the history of everyday life. By placing these literatures in conversation with each other, I create a complex portrait of my subjects as socialists, intellectuals, and private individuals. Looking at these fields together allows me to bring new insights to each. Examining the lives of prominent scientists and writers not usually remembered for their socialist activism I fill the gaps of the Romanian socialist pantheon and recover the ideological commitments of the politically unaffiliated. Placing the specialized analyses of literary history in the broader social, cultural and national environments in which Gherea and other socialist literary critics operated I trace their visibility to their involvement in the making of a national literary canon. This contribution is both unusual for Marxist critics, who generally examine already consecrated Western classics, and very relevant in the context of a nation-building young state. Going beyond the apparently antagonistic relation between socialism and nationalism, I show that socialism was vulnerable to, and compatible with, nationalist agendas. Looking at influential socialist researchers whose laboratories became important nodes in transnational scientific networks, I question the distinction between alleged scientific centers and peripheries and integrate Eastern Europe in wider European and global cultural and intellectual histories.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2021-08-01The student, Anca Mandru, accepted the attached license on 2019-07-02 at 17:28.The student, Anca Mandru, submitted this Dissertation for approval on 2019-07-02 at 17:39.This Dissertation was approved for publication on 2019-07-03 at 08:40.DSpace SAF Submission Ingestion Package generated from Vireo submission #14139 on 2019-11-26 at 14:00:49Made available in DSpace on 2019-11-26T20:58:36Z (GMT).

The Use of Salivary Levels of Matrix Metalloproteinases as an Adjuvant Method in the Early Diagnosis of Oral Squamous Cell Carcinoma: A Narrative Literature Review
No full textOral squamous cell carcinoma (OSCC) is an aggressive malignancy with increased mortality, in which the early diagnosis is the most important step in increasing patients’ survival rate. Extensive research has evaluated the role of saliva as a source of diagnostic biomarkers, among which matrix metalloproteinases (MMPs) have shown a valuable potential for detecting even early stages of OSCC. The aim of this review was to present recent clinical data regarding the significance of salivary MMPs in the detection of early malignant transformation of the oral mucosa. A narrative review was conducted on articles published in PubMed, Cochrane Library, Web of Science, EBSCO and SciELO databases, using specific terms. Our search revealed that MMP-1, MMP-2, MMP-3, MMP-8, MMP-9, MMP-10, MMP-12 and MMP-13 had significantly higher levels in saliva from patients with OSCC compared to controls. However, the strength of evidence is limited, as most information regarding their use as adjuvant diagnostic tools for OSCC comes from studies with a low number of participants, variable methodologies for saliva sampling and diagnostic assays, and insufficient adjustment for all covariates. MMP-1, MMP-3 and MMP-9 were considered the most promising candidates for salivary diagnosis of OSCC, but larger studies are needed in order to validate their clinical application

No full textAbstractPurpose of studyBlending different modalities and methods of EFL learning is gaining momentum as it assists teachers in designing relevant and engaging activities to drive learners from passive to active participants involved in their own learning.Sources of EvidenceThe paper will report on a class-size project of blending two elements within the face-to-face component: self-paced asynchronous learning (Voki, Fotobabble, Showbeyond) and opportunities for collaboration (personal blogs).Findings and ResultsThe project outcomes demonstrate that offering students a chance to collaborate and work outside of the class environment, at their own pace, through employment of web communication speaking and writing tools enhances learning and generates high levels of enthusiasm for communication in the target language.ConclusionFinding the optimum blend of methods and tools augments EFL learning and impacts positively on motivation, disposition and satisfaction, which are likely to enhance learning
A Model for Developing Adult Learner Effectiveness in New Roles and Environments
No full textAbstractIntroduction. A glance at Plato's Republic confirms that the notion of learning through life is hardly new. Thus, with the development of ‘adult education’ came the view that education should be lifelong. Nowadays it must not be regarded as a luxury for a few outstanding individuals, nor as a stage of early manhood, but it is envisaged as a permanent necessity, an inseparable aspect of employment, and a part of life. Since life is viewed as learning, education has no endings, it is a cognitive process internal to the learner, which can occur both incidentally and in planned educational activities.Purpose of study/Sources of Evidence. Adult learners are employees or future employees who cross an organizational boundary that requires performance in a new organizational role or environment. Adult learner's development can be defined as all development processes used to advance adult students to desired levels of performance.This paper attempts to draft a model for developing EFL (English as a Foreign Language) adult learner effectiveness that could represent a foundation for developing more comprehensive performance improvement interventions. Three key questions are addressed: what learning content should be included in a comprehensive adult learner development program, what learning strategies are most effective to facilitate that learning, and what should be the role of educational institutions.Findings and Results. The conclusions of the study reveal that adult learners need to engage in four content domains in order to achieve performance goals: individual, people, organization, and work tasks. This development process is not linear, but rather cyclical, with novice learners having to cycle through learning tasks and learning events repeatedly. Conclusion. Effectiveness in new roles and environments can be achieved by interacting with other people, therefore social learning skills are of great importance, and learning occurs when engaged in work projects. Self-directed learning becomes the norm for adult learners who have to take initiative to go beyond their job-description. Adult learning has no definite beginning and ending points, it is a complex but continuous process
