Estudio comparativo : la moda según Vogue y Vanity Fair

La moda, tal y como la entendemos en la actualidad, hace su aparición a mediados del siglo XIV. Desde entonces, y hasta las grandes pasarelas y semanas de la moda que tenemos en la actualidad, hay un largo camino donde vemos como década tras década evoluciona toda esta industria. Aunque la historia de la prensa especializada en moda tiene sus inicios en el siglo XVII no fue hasta el siglo XIX cuando se focalizaron en el sector femenino. Desde el Mercure Galant de la Francia de 1672, pasando por Harper´s Bazaar en los Estados Unidos en 1867 hasta el nacimiento de la Telva española en 1963 la prensa especializada en moda irá evolucionando y creciendo hasta encontrar una posición determinante y fuerte. Dentro del ranking de revistas especializadas en moda encontramos la llamada “biblia de la moda”: Vogue, considerada todo un referente en este ámbito y que nace en Estados Unidos en 1893. Dentro de la misma editorial, Condé Nast Publications, nacerá en 1913 Vanity Fair, la revista más influyente de la cultura a nivel mundial. En este contexto es objetivo de este estudio analizar el tratamiento periodístico de las revistas Vogue y Vanity Fair acerca de la moda y su influencia en la sociedad. Se pretende, en última instancia, establecer una comparativa entre dos referentes periodísticos del mundo de la moda a lo largo de los años y hasta el momento actual.Universidad de Sevilla.

The impact of zinc oxide particle morphology as an antimicrobial and when incorporated in poly(3-hydroxybutyrate-co-3-hydroxyvalerate) films for food packaging and food contact surfaces applications

In this work, zinc oxide (ZnO) micron and nano sized-particles with different morphologies were synthesized by aqueous precipitation and evaluated as antimicrobial agents against foodborne pathogens. The most effective bactericide system was selected to prepare active poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) films by three different methods (i) direct melt-mixing, (ii) melt-mixing of preincorporated ZnO into PHBV18 (18 mol% valerate content) fiber mats made by electrospinning, and, (iii) as a coating of the annealed electrospun PHBV18/ZnO fiber mats over compression molded PHBV. Results showed that ZnO successfully improved the thermal stability of the PHBV18, being the preincorporation method the most efficient in mitigating the negative impact that the PHBV18 had on the thermal stability, barrier and optical properties of the PHBV films. Similar behavior was found for the coating structure although this film showed effective and prolonged antibacterial activity against Listeria monocytogenes. This study highlights the suitability of the PHBV/ZnO nanostructures for active food packaging and food contact surface applications.This work was financially supported by the Spanish Ministry of Economy and Competitiveness (MAT2012-38947-C02-01 and AGL2015-63855-C2-1-R).

Antiviral properties of silver nanoparticles against norovirus surrogates and their efficacy in coated polyhydroxyalkanoates systems

Silver nanoparticles (AgNP) have strong broad-spectrum antimicrobial activity and gained increased attention for the development of AgNP based products, including medical and food applications. Initially, the efficacy of AgNP and silver nitrate (AgNO3) was evaluated for inactivating norovirus surrogates, the feline calicivirus (FCV) and the murine norovirus (MNV). These norovirus surrogates were exposed to AgNO3 and AgNP solutions for 24 h at 25 °C and then analyzed by cell-culture assays. Both AgNP and silver ions significantly decreased FCV and MNV infectivity in a dose-dependent manner between concentrations of 2.1 and 21 mg/L. Furthermore, poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) films were prepared by depositing a coating of thermally post-processed electrospun PHBV18/AgNP fiber mats over compression moulded PHBV3 films. After 24 h exposure at 37 °C and 100% RH, no infectious FCV were recovered when in contact with the AgNP films while MNV titers decreased by 0.86 log. The morphology of the PHBV18 and PHBV18/AgNP fibers studied by SEM showed smooth and continuous fibers in both cases and the EDAX analysis confirmed the homogeneously distribution of AgNP into the coating and onto the PHBV3/PHBV18 layer. This study showed, for the first time, the suitability of the PHBV18/AgNP electrospun coating for antiviral surfaces.This work was supported by the Spanish Ministry of Economy and Competitiveness (MINECO) (RYC-2012-09950, RYC-2014-158, AGL2015-63855-C2-1-R and INIA grant RTA2014-00024-C04-03).

Social Learning for Facilitating Dialogue and Understanding of the Ecosystem Services Approach: Lessons from a Cross-Border Experience in the Alboran Marine Basin

Social learning (SL) appears to have considerable potential to enhance the impact of the ecosystem services approach (ESA) discourse on policy and society. However, empirical research to better understand the processes that support SL, the effects it generates, and the conditions that enable such learning is limited. This study assesses the ability of SL to enhance dialogue and understanding of the ESA to support transformative social change in governance practice in the Alboran Marine Basin. To do so, we conducted a specifically designed SL process oriented towards the ESA as a governance approach in this marine region. The SL process was developed through three interlinked workshops involving scientists, decision-makers and local users from Spain and Morocco, the two countries that share the governance of this social-ecological system. The results revealed that the SL process progressively facilitated (i) a more inclusive and constructive ecosystem services dialogue, (ii) a better understanding of the social-ecological system in which the actors were embedded, (iii) an enhanced recognition of science-policy-society complementarities to address sustainability issues, and (iv) a gradual social transformation towards more sustainable and equitable governance. Via the SL process, a variety of factors were identified as contributing to the creation of four relevant conditions that facilitated its successful operationalisation. These conditions included (i) the generation of trust and shared understanding, (ii) the facilitation of knowledge exchanges between actor groups across frontiers, (iii) the promotion of more democratic participation, and (iv) the co-production of practical outcomes. These contextual insights provided empirical evidence of the prominent role SL can play to enhance dialogue and understanding of the ESA for supporting its adoption as governance practice. On this basis, it is argued that operationalising SL in those processes focused on making the ESA relevant to policy and society is pivotal to its implementation in governance practice

Effect of Myofascial Therapy on Pain and Functionality of the Upper Extremities in Breast Cancer Survivors: A Systematic Review and Meta-Analysis

(1) Objective: The purpose was to analyze the effectiveness of myofascial therapy on musculoskeletal pain and functionality of the upper extremities in female breast cancer survivors, and to evaluate the changes in range of motion, quality of life, and mood state of these patients. (2) Methods: Systematic searches were performed on the MEDLINE/PubMed, Web of Science, Scopus, and Physiotherapy Evidence Databases for articles published until October 2020, in order to identify randomized controlled trials which analyzed the effectiveness of myofascial therapy as compared to a control group, passive treatment, placebo, or another intervention, and allowed co-interventions on female breast cancer survivors. Two reviewers examined the sources individually, calculated the risk of bias and extracted the data (PROSPERO number CRD42020215823). (3) Results: A total of eight RCTs were included. The results suggested that myofascial therapy does not have a greater statistically significant immediate effect on pain intensity (SMD: -0.15; 95% CI -0.48, 0.19), functionality (SMD: -0.17; 95% CI -0.43, 0.09) and range of motion in flexion (SMD: 0.30; 95% CI -0.13, 0.74) than an inactive, passive treatment or another intervention. However, a statistically significant result was observed for the abduction shoulder in favor of the experimental group (SMD: 0.46; 95% CI 0.05, 0.87; p = 0.03). (4) Conclusion: In general, although we found greater overall effects in support of the intervention with myofascial therapy than other control groups/types of interventions, the subgroup analysis revealed inconsistent results supporting myofascial therapy applied to breast cancer survivors

Efficacy of Cinnamaldehyde Against Enteric Viruses and Its Activity After Incorporation Into Biodegradable Multilayer Systems of Interest in Food Packaging

Cinnamaldehyde (CNMA), an organic compound that gives cinnamon its flavor and odor, was investigated for its virucidal activity on norovirus surrogates, murine norovirus (MNV) and feline calicivirus (FCV), and hepatitis A virus (HAV). Initially, different concentrations of CNMA (0.1, 0.5 and 1 %) were individually mixed with each virus at titers of ca. 6–7 log10 TCID50/ml and incubated 2 h at 4 and 37 °C. CNMA was effective in reducing the titers of norovirus surrogates in a dose-dependent manner after 2 h at 37 °C, while HAV titers were reduced by 1 log10 after treatment with 1 % of CNMA. When incubation time was extended, HAV titers were reduced by 3.4 and 2.7 log10 after overnight incubation at 37 °C with 1 and 0.5 % of CNMA, respectively. Moreover, this paper analyzed, for the first time, the antiviral activity of adding an active electrospun interlayer based on zein and CNMA to a polyhydroxybutyrate packaging material (PHB) in a multilayer form. Biodegradable multilayer systems prepared with 2.60 mg/cm2 (~9.7 %) of CNMA completely inactivated FCV according to ISO 22196:2011, while MNV titers were reduced by 2.75 log10. When the developed multilayer films were evaluated after one month of preparation or at 25 °C, the antiviral activity was reduced as compared to freshly prepared multilayer films evaluated at 37 °C. The results show the excellent potential of this system for food contact applications as well as for active packaging technologies in order to maintain or extend food quality and safety.This work was supported by the Spanish Ministry of Economy and Competitiveness (MINECO) (RYC-2012-09950, AGL2015-63855-C2-1 and INIA Grant RTA2014-00024-C04-03).

Effectiveness of video-assisted debriefing versus oral debriefing in simulation-based interdisciplinary health professions education: A randomized trial

* Corresponding author at: Department of Nursing, Faculty of Health Sciences, University of Granada, Granada 18016, Spain. E-mail address: [email protected] (R. Gil-Gutiérrez).Aim We aimed to compare the debriefing experience, simulation assessment, reflection, anxiety and simulation satisfaction of using oral debriefing versus video-assisted debriefing after a simulated clinical session in an interdisciplinary cohort of health sciences students. Background Debriefing is a reflective process that takes place after a clinical simulation and that can be performed either in a traditional way (oral) or using video-assisted debriefing. Design A randomized controlled trial was conducted in 143 health sciences students (35.7% male, 61.5% female). Methods The simulation scenario was designed to evaluate the procedure for donning and doffing personal protective equipment. Differences in debriefing experience, simulation assessment, reflection, anxiety and satisfaction were assessed. Results Regarding debriefing experience, significant differences were observed for the category “learning” (34.9 (6.13) vs. 36.7 (3.89); p = 0.039). For simulation assessment, significantly higher scores for all categories were identified in video-assisted debriefing compared with oral debriefing (p<0.001). There were also significant differences between the oral debriefing versus video-assisted debriefing for the overall score of reflection ability (86.97 (10.55) vs. 90.74 (9.67); p=0.028) as well as for the category “reflective communication” (24.72 (3.77) vs 26.04 (4.07); p=0.047). Perceived satisfaction was significantly higher in the video-assisted debriefing group compared with oral debriefing group (p <0.001). For anxiety, no significant differences were observed between debriefing groups. Conclusion Video-assisted debriefing after a simulated clinical session improves debriefing experience, simulation assessment, reflection and simulation satisfaction, but does not increase anxiety compared with oral debriefing among health sciences students.*Funding for open access charge: Univeresidad de Granada/CBUA

A multi reference point based index to assess and monitor European water policies from a sustainability approach

The scarcity of water resources is a serious problem that concerns governments and international institutions. The importance of water resources and the expectations of billions of people with serious water shortages and subsequent food shortages have made European water policy makers focus all their attention on the sustainability of water as a resource. In this paper we propose a new Water Sustainability Indicator based on a MultiReference methodology (WSI-MR) which permits modeling compensation between the analyzed criteria and provides a participative approach. The WSI-MR provides results based on 19 variables grouped into 5 dimensions: availability, access, resilience, good governance and economic capacity. The indicator was applied to assess water sustainability in 27 European countries. The results showed that Finland, the Netherlands, Sweden and the United Kingdom obtained the best global results in terms of weak water (compensatory) sustainability. Using a non-compensatory approach, no country gained acceptable results in terms of strong sustainability. Some subdimensions related to climate change and the state of freshwater resources were detected as especially vulnerable in all the analyzed countries. Finally, the study identified some eastern European countries with low GDP and good performance of availability and cost of water, where bad results in terms of governance and water productivity could jeopardize water sustainability in the event of a potential economic development, if these limitations are not addressed. In a context of economic and political instability, due to the current armed conflict in nearby countries such as Ukraine, it is especially important to pay attention to these countries, whose good governance indicators could worsen even more. The proposed indicator is useful to identify warning signs and can contribute to the improvement in decision-making processes and to monitoring international water policies

Quantitative proteomic analysis of Pseudomonas pseudoalcaligenes CECT5344 in response to industrial cyanide-contain ing wastewaters using Liquid Chromatography- Mass Spectrometry/Mass Spectrometry (LC- MS/MS)

Biological treatments to degrade cyanide are a powerful technology for cyanide removal from industrial wastewaters. It has been previously demonstrated that the alkaliphilic bacterium Pseudomonas pseudoalcali genes CECT5344 is able to use free cyanide and several metal − cyanide complexes as the sole nitrogen source. In this work, the strain CECT5344 has been used for detoxification of the different chemical forms of cyanide that are present in alkaline wastewaters from the jewelry industry. This liquid residue also contains large concentration s of metals like iron, copper and zinc, making this wastewater even more toxic. To elucidate the molecular mechanisms involved in the bioremediation process, a quantitative proteomic anal- ysis by LC-MS/MS has been carried out in P . pseudoalcaligene s CECT5344 cells grown with the jewelry residue as sole nitrogen source. Different proteins related to cyanide and cyanate assimilation, as well as other proteins involved in transport and resistance to metals were induced by the cyanide-cont aining jewelry residue. GntR-like regulatory proteins were also induced by this industrial residue and mutational analysis revealed that GntR-like regulatory proteins may play a role in the regulation of cyanide assimilation in P . pseudoalcaligene s CECT5344. The strain CECT5344 has been used in a batch reactor to remove at pH 9 the dif- ferent forms of cyanide present in industrial wastewaters from the jewelry industry (0.3 g/L, ca . 12 mM total cyanide, including both free cyanide and metal − cyanide complexes). This is the first report describing the biological removal at alkaline pH of such as elevated concentra- tion of cyanide present in a heterogeneou s mixture from an industrial source
