Efficiency of COVID-19 Testing Centers in Iran: A Data Envelopment Analysis Approach
2022
AbstractObjective:The purpose of this study is to investigate the efficiency of the Iranian Red Crescent Society (IRCS) in managing their nonmonetary resources involved in coronavirus disease 2019 (COVID-19) response.Methods:For this purpose, the data envelopment analysis approach was used to measure the efficiency, considering the number of personnel and vehicles and screened passengers as the input and output parameters, respectively. It was examined the efficiency of 10 IRCS’s branches given 17 d of screening operation. For the analysis, the DEA SolverPro software 15a version was used.Results:The results show that only 1 branch had been fully efficient in using the resources, while 5 bra…
Antioxidant Effects of Dietary Supplements on Adult COVID-19 Patients: Why Do We Not Also Use Them in Children?
2022
Respiratory tract infections (RTIs) are very common in children, especially in the first five years of life, and several viruses, such as the influenza virus, Respiratory Syncytial Virus, and Rhinovirus, are triggers for symptoms that usually affect the upper airways. It has been known that during respiratory viral infections, a condition of oxidative stress (OS) occurs, and many studies have suggested the potential use of antioxidants as complementary components in prophylaxis and/or therapy of respiratory viral infections. Preliminary data have demonstrated that antioxidants may also interfere with the new coronavirus 2’s entry and replication in human cells, and that they have a role in …
Il ruolo del dirigente scolastico in tempi di pandemia da Covid-19: tra responsabilità legale e pedagogica
2021
In seguito all’attuazione della legge 59/1997 che con l’art. 21 conferisce l’autonomia didattica e organizzativa alle istituzioni scolastiche, la dirigenza della scuola è investita di una doppia carica che si snoda tra la responsabilità legale e la responsabilità pedagogica. Ciò si traduce per il Dirigente Scolastico in un incremento del suo potere d’azione in tutti gli ambiti della gestione della scuola (Di Liberto et al., 2019, p.121). La letteratura scientifica, peraltro, sottolinea che il successo delle imprese è strettamente correlato alla qualità della leadership, dell’organizzazione manageriale e alle pratiche educative (Bloom, Van Reenen, 2010). È possibile affermare che per attende…
Car d'hom cert era: Pràctiques de canibalisme en el Mesolític de les Coves de Santa Maira (Castell de Castells, la Marina Alta, Alacant)
2017
Es presenten evidències de pràctiques antropofàgiques en un grup del Mesolític mediterrani. S'han documentat trenta restes humanes en el nivell mesolític de les coves de Santa Maira. A més de la descripció de les marques antropogèniques identificades, també se situa la troballa en el seu context regional dins les pautes de subsistència dels grups mesolítics de la zona, i es plantegen hipòtesis sobre la seua intencionalitat. Se presentan evidencias de prácticas antropofágicas en un grupo del Mesolítico mediterráneo. Se han documentado treinta restos humanos en el nivel mesolítico de Coves de Santa Maira. Además de la descripción de las marcas antropogénicas identificadas, también se sitúa el…
Research and Projects for the Recovery of the “Tifeo” Power Station in Augusta
2015
The buildings of the Tifeo Augusta Power Station (SR) significantly tell us, even today, the history of the Sicilian industrial dream at the end of the Fifties. However, with the passing of time, it revealed the underlying contradictions still present today in Augusta together with polluting and oppressive petrochemical plants built during those times. Regardless of any recovery theory about the Augusta Power Station, it is clear that an open and multidisciplinary look cannot be ignored, locating the power station in the actual and future setting of the vastest territory in which it is sited. The past, the present and, of course, the future of the Augusta area are tightly connected to the s…
Effects of states governments restrictions related on Coronavirus disease (COVID-19) on states economy - comparison of Baltic States, Sweden, and Bel…
2021
In order to limit the spread of COVID-19, states have gradually implemented restrictions mandating school and kindergarten closures, postponing academic semesters and prohibiting visits to nursing homes to protect the elderly, borders were closed, states prohibited physical contact with more than one person from outside one's household, and other restrictions. This paper examines the economic effects of policies to contain Covid-19 in Baltic States by comparing they with experience of Sweden and Belarus where approach was less stringent and based more on social responsibility than legal obligations compared to the other European states
Online grocery shopping before and during the COVID-19 pandemic: A meta-analytical review.
2021
The COVID-19 pandemic has forced people to limit their physical interactions, which has led to explosive growth in online grocery shopping. However, there is no clear consensus in the retailing literature on whether consumers prefer to buy groceries online. The objective of this current study is to synthesize research about online grocery shopping published before and during the COVID-19 pandemic and to develop a conceptual framework about online grocery purchase intentions and their determinants, the mediation effects of consumers’ attitudes, the moderating effects of COVID-19, and control variables. The meta-analysis presents data derived from 50 independent samples with a sample size of …

Performative Control and Rhetoric in Aotearoa New Zealand’s Response to COVID-19
2021
This article analyses how specific nodal points of performative control developed and consequently structured the discourse on Aotearoa New Zealand’s response to the COVID-19 pandemic. It identifies these points by adopting a rhetorical-performative approach to uncover three particular performances of control that articulated the pandemic in Aotearoa New Zealand, from the diagnosis of the first COVID-19 case in the country in February 2020 through to October 2020. This period of analysis covers the emergence, subsequent nationwide lockdown, elimination, and re-emergence of the virus. There are three distinct nodal points that unfold as key to the nation’s ability to control COVID-19: the he…
Targeting the mevalonate pathway for improved anticancer therapy.
2009
The mevalonate pathway is important for the generation of isoprene moieties thereby providing the basis for the biosynthesis of molecules required for maintaining membrane integrity, steroid production and cell respiration. Additionally, isoprene precursors are indispensable for the prenylation of regulatory proteins such as Ras and Ras-homologous (Rho) GTPases. These low molecular GTP-binding proteins play key roles in numerous signal transduction pathways stimulated upon activation of cell surface receptors by ligand binding. Thus, Ras/Rho proteins eventually regulate cell proliferation, tumor progression and cell death induced by anticancer therapeutics. Lipid modification of Ras/Rho pro…
