Dairy cattle, livelihoods and resilience in Gaza Strip: a case study

As an effect of a protracted situation of conflict, the economy in Gaza Strip has largely developed through international humanitarian assistance. Over the time, the isolation of markets, widespread unemployment, and the economic crisis have caused a serious decline in the population living standards, with a high level of food insecurity. Today, the population in Gaza Strip has dramatically increased reaching an estimated 1.65 million in an area of only 360 km2 (PCBS). The rapid increase in urban population (3.2% of yearly growth rate), land scarcity and the challenge of food security have accelerated the phenomenon of urban agriculture. In Gaza Strip, despite many constraints, agriculture and related activities are still offering the opportunity of food, income and employment for the local population. By participating in activities related to projects of international cooperation promoting the dairy cattle sector we have investigated ways of breeding cattle and proposed a reflection on the sector, highlighting the main strengths, weaknesses, opportunities and constraints. We have also explored the livelihoods of dairy cattle keepers and analysed related resilience and sustainability

Measuring the effects of transdisciplinary research: the case of a social farming project

Social farming (SF) is an innovative concept belonging to a grey zone occupied by agriculture, social, education and health sectors. It involves various private and public actors who work together to co-create and share new collective knowledge. SF initiatives also involve many policies and tools that need to be reframed in order to facilitate the evaluation of these practices. Research in SF includes the active role of researchers in medium-term initiatives, involving a large number of stakeholders.Thus an evaluation of SF practices is crucial in developing and planning future actions. The complex nature of SF has led to the use of a transdisciplinary approach for the evaluation of its initiatives.This paper explains the transdisciplinary process used in a SF project, describes the nature of the collaborative relationships between researchers and others stakeholders, and examines the factors that inhibit and facilitate this collaboration. The paper highlights the important effects the transdisciplinary approach could have on the future of SF, in terms of network building, the co-production of knowledge, and the development of innovative practices

Creating the cultures of the future: cultural strategy, policy and institutions in Gramsci. Part three: Is there a theory of cultural policy in Gramsci’s prison notebooks?

In this article, I argue that Gramsci’s prison notes on questions of cultural strategy, policy and institutions, which have so far been largely overlooked by scholars, provide further analytical insights to those offered by his more general concepts. Together they enrich the theoretical underpinnings for critical frameworks of analysis as well as for radical practices of cultural strategy, cultural policy-making and cultural organisation. On the basis of a detailed analysis of these notes, I then answer the question of whether they amount to a theory of cultural policy

Zinc Polyaleuritate Ionomer Coatings as a Sustainable, Alternative Technology for Bisphenol A-Free Metal Packaging

Sustainable coatings for metal food packaging were prepared from ZnO nanoparticles (obtained by the thermal decomposition of zinc acetate) and a naturally occurring polyhydroxylated fatty acid named aleuritic (or 9,10,16-trihydroxyhexadecanoic) acid. Both components reacted, originating under specific conditions zinc polyaleuritate ionomers. The polymerization of aleuritic acid into polyaleuritate by a solvent-free, melt polycondensation reaction was investigated at different times (15, 30, 45, and 60 min), temperatures (140, 160, 180, and 200 °C), and proportions of zinc oxide and aleuritic acid (0:100, 5:95, 10:90, and 50:50, w/w). Kinetic rate constants calculated by infrared spectroscopy decreased with the amount of Zn due to the consumption of reactive carboxyl groups, while the activation energy of the polymerization decreased as a consequence of the catalyst effect of the metal. The adhesion and hardness of coatings were determined from scratch tests, obtaining values similar to robust polymers with high adherence. Water contact angles were typical of hydrophobic materials with values ≥94°. Both mechanical properties and wettability were better than those of bisphenol A (BPA)-based resins and most likely are related to the low migration values determined using a hydrophilic food simulant. The presence of zinc provided a certain degree of antibacterial properties. The performance of the coatings against corrosion was studied by electrochemical impedance spectroscopy at different immersion times in an aqueous solution of NaCl. Considering the features of these biobased lacquers, they can be potential materials for bisphenol A-free metal packagingPeer reviewe

High Risk of Secondary Infections Following Thrombotic Complications in Patients With COVID-19

Background. This study’s primary aim was to evaluate the impact of thrombotic complications on the development of secondary infections. The secondary aim was to compare the etiology of secondary infections in patients with and without thrombotic complications. Methods. This was a cohort study (NCT04318366) of coronavirus disease 2019 (COVID-19) patients hospitalized at IRCCS San Raffaele Hospital between February 25 and June 30, 2020. Incidence rates (IRs) were calculated by univariable Poisson regression as the number of cases per 1000 person-days of follow-up (PDFU) with 95% confidence intervals. The cumulative incidence functions of secondary infections according to thrombotic complications were compared with Gray’s method accounting for competing risk of death. A multivariable Fine-Gray model was applied to assess factors associated with risk of secondary infections. Results. Overall, 109/904 patients had 176 secondary infections (IR, 10.0; 95% CI, 8.8–11.5; per 1000-PDFU). The IRs of secondary infections among patients with or without thrombotic complications were 15.0 (95% CI, 10.7–21.0) and 9.3 (95% CI, 7.9–11.0) per 1000-PDFU, respectively (P = .017). At multivariable analysis, thrombotic complications were associated with the development of secondary infections (subdistribution hazard ratio, 1.788; 95% CI, 1.018–3.140; P = .043). The etiology of secondary infections was similar in patients with and without thrombotic complications. Conclusions. In patients with COVID-19, thrombotic complications were associated with a high risk of secondary infections
