¿Aliados naturales? Sindicatos, movimientos sociales y tercer sector durante la crisis económica de 2008 en España
Authors: Ribón Seisdedos María Antonia , Roca Martínez Beltrán 
Published: July 2022

El presente artículo pone a prueba la tesis de John Kelly sobre la condición de “aliados naturales” de las organizaciones sindicales y los movimientos sociales. Para ello, se estudia la actuación de sindicatos, el 15M y las organizaciones del tercer sector en España en el contexto de las políticas de austeridad que se impulsaron desde el Gobierno a partir de la crisis económica de 2008. Tras una revisión teórica sobre las relaciones entre sindicatos y movimientos y la contextualización de las protestas tras la crisis de 2008, el artículo analiza la respuesta sindical ante la crisis y las relaciones de convergencia y competencia entre las organizaciones sindicales, el tejido asociativo y el movimiento 15M. Posteriormente, se analizan las estrategias sindicales de la creación de Mareas y la de la Cumbre Social. Los resultados ponen de manifiesto que el campo sindical y el de las organizaciones de la sociedad civil contienen importantes fracturas y contradicciones, que dan lugar a diferentes estrategias sindicales, lo que obliga a presentar algunas objeciones y matizaciones a la tesis de los aliados naturales. Se concluye que factores como las tradiciones sindicales, los contextos de economía política, la competencia entre organizaciones y las propias características de los movimientos sociales, explican la diversidad de modos de relación entre sindicatos y movimientos, obligando a desarrollar aproximaciones más complejas y sensibles a las especificidades de cada contexto histórico y geográfico.
Las organizaciones sindicales como agentes de cambio colaborativo. El modelo inclusivo-participativo de empresa
Authors: Chica Páez Yolanda , Ruiz-Roqueñi Maite 
Published: July 2022

Este artículo analiza, desde la perspectiva sindical, la propuesta del modelo inclusivo-participativo de empresa (MIPE), diseñada y consensuada por diferentes personas pertenecientes al mundo político, sindical y empresarial de Euskadi. Pese a la existencia de diversas experiencias en empresas participativas en la mayoría de países de la Unión Europea, en nuestro país, este modelo de empresa ha tenido escaso desarrollo e implementación práctica, estando en proceso de gestación. La fundamentación teórica de la participación y la identificación de los modelos existentes delimita la discusión teórica.A través de entrevistas personales mantenidas con representantes de los sindicatos más representativos de Euskadi (CCOO, CGT, ELA, LAB y UGT) y de la Asociación de Amigos de Arizmendiarrieta (ALE) y la Fundación Arizmendiarrieta, como entidades promotoras del MIPE, el estudio aporta un análisis cualitativo de las potencialidades y limitaciones que presenta el modelo, así como la identificación de los elementos clave a tener en consideración en su diseño institucional y organizacional, de cara a su desarrollo en la praxis empresarial. El trabajo aporta elementos de análisis que pueden servir a un debate más completo e informado sobre la participación de las personas trabajadoras en la empresa y permitir así avanzar, desde el ámbito sindical, en el desarrollo de modelos de empresa participativos.
Pagine al vento. Le identità letterarie della Patagonia in una prospettiva geografica
Authors: Gilardi Thomas 
Published: July 2022

The analysis of the Patagonian literature from a geographical perspective allows to show some recurring themes, with which the characters of the various works measure and confront each other, constructing and affirming their identity in relation to the places. Among the recognized themes is that of regional citizenship in a condition of cross-border marginality, in which the internal and international migratory phenomenon overlaps with the reshaping and rediscovery of the identities of pre-existing populations, while tourism commercializes the imaginary.
Zero Waste for geographical education on sustainability
Authors: Guaran Andrea , Venturini Federico 
Published: July 2022

Environmental education is vital for raising awareness of sustainable development. Zero Waste is a holistic model that goes beyond waste reduction and recycling, and calls for a reshaping of contemporary modes of production and consumption while also promoting active citizenship awareness. Exploring Zero Waste principles, this article situates and demonstrates its alignment with key international documents, such as the United Nations’ 2030 Agenda for Sustainable Development. Already used in some educational contexts, the Zero Waste model has the potential to encourage a new perspective to fundamentally reconsider and redesign our relationship to what it means to be actively more sustainable, through a systemic and circular approach. We outline how educational geography and sustainability practices can both benefit from, and support, a dialogue with Zero Waste principles.
Dal Grand Tour all’educazione globale: gli immaginari europei nelle performance visuali di viaggio
Authors: Rabbiosi Chiara 
Published: July 2022

This paper frames international student mobilities throughout Europe as a novel Grand Tour to revise the social and material tourist encounter with the continent and ordinary life therein, and advance cultural and political debates concerning the European space. This is done by analysing how European imaginaries are enacted in three tourist pictures of Rome, collected through photo-elicited focus groups with international students. The methods employed in the latest visual and tourism studies were used herein. This study shows how persistent and often stereotyped representations of Europe come together with critical readings of the European society, and highlights the importance – in the geographical analysis of tourist photography – of including more-than-epresentational accounts of what happens before and after shooting a tourist picture.

Background
Panax notoginseng is an important herbal medicine in China, where this crop is cultivated by replanting of seedlings. Root rot disease threatens the sustainability of P. notoginseng cultivation. Water flooding (WF) is widely used to control numerous soilborne diseases, and biogas slurry shows positive effects on the soil physiochemical properties and microbial community structure and has the potential to suppress soilborne pathogens. Hence, biogas slurry flooding (BSF) may be an effective approach for alleviating root rot disease of P. notoginseng; however, the underlying mechanism needs to be elucidated.

Methods
In this study, we conducted a microcosm experiment to determine if BSF can reduce the abundance of pathogens in soil and, alleviate root rot of P. notoginseng. Microcosms, containing soil collected from a patch of P. notoginseng showing symptoms of root rot disease, were subjected to WF or BSF at two concentrations for two durations (15 and 30 days), after which the changes in their physicochemical properties were investigated. Culturable microorganisms and the root rot ratio were also estimated. We next compared changes in the microbial community structure of soils under BSF with changes in WF and untreated soils through high-throughput sequencing of bacterial 16S rRNA (16S) and fungal internal transcribed spacer (ITS) genes amplicon.

Results
WF treatment did not obviously change the soil microbiota. In contrast, BSF treatment significantly altered the physicochemical properties and reshaped the bacterial and fungal communities, reduced the relative abundance of potential fungal pathogens (Fusarium, Cylindrocarpon, Alternaria, and Phoma), and suppressed culturable fungi and Fusarium. The changes in the microbial community structure corresponded to decreased root rot ratios. The mechanisms of fungal pathogen suppression by BSF involved several factors, including inducing anaerobic/conductive conditions, altering the soil physicochemical properties, enriching the anaerobic and culturable bacteria, and increasing the phylogenetic relatedness of the bacterial community.

Conclusions
BSF application can reshape the soil microbial community, reduce the abundance of potential pathogens, and alleviate root rot in P. notoginseng. Thus, it is a promising practice for controlling root rot disease in P. notoginseng.

The main purpose of the study was to determine the extent of knowledge of Khasi tribe on improved cultivation practices of tomato. The study was conducted purposively in Mawryngkneng Block in East Khasi Hills District, Meghalaya in the year 2022. A descriptive research design was applied for the study. The primary data was collected from 120 respondents by personal interview method using pre - structure interview schedule Knowledge of the farmers was measured by asking 13 questions in respect to tomato cultivation practices. Pearson’s Product Moment Coefficient of Correlation (r) was employed to determine the relationship between independent variables and knowledge of the respondents. Finding showed that (78.33%) of the respondents had medium level of knowledge, (10%) of the respondents had high level of knowledge and only (3.33%) of the respondents had low level of knowledge about improved cultivation practices of tomato. Co-efficient of correlation (r) analysis indicated that land holding, farming experience, extension contact and sources of information are significantly associated with knowledge of farmers whereas variables like: age, education, annual income, family type, size of family, and occupation was found to be non-significant with the knowledge of farmers towards improved cultivation practices of tomato. Extension Workers should frequently contact with the farmers for disseminating of proper information which in turn lead to better implementation of improved practices.

The “Development of Operating Model for the Design of Stirrer Arms of Slurries: Empirical Evaluation of Stirrer Arms” is reported. Previous work reviewed the “Operating Model for the Design of Stirrer Arms of Slurries” and identified the Two Z and TETE stirrer arms as the most effective. Furthermore, subsequent work “Development of Operating Model for the Design of Stirrer Arms of Slurries: Design and Fabrication of Stirrer Arms” designed and fabricated the Two Z and TETE stirrer arms, evaluated the theoretical (expected) Slurry Mixing Power and Order of Merit Analysis. The current work did the empirical evaluation of the Two Z and TETE stirrer arms and also the hybrid Two Z - TETE stirrer arms. The Objectives of this research were: to do the mixing performance tests in terms of mixing time, power and energy consumed by the Two Z blade, TETE blade and Two Z – TETE hybrid blade using the constituted slurry; to validate the theoretical (predicted or expected) mixing power for the Two Z blade, TETE blade and Two Z – TETE hybrid blade by comparison with the empirical power using the Chi Square; to do the Power, Time and Energy order of merit analysis for the Two Z blade, TETE blade and the Two Z – TETE hybrid blade. Using the Philips HR 1565 mixer with the Akamu (pap) (Viscosity calibrated) slurries, the time and current drawn for complete and consistent slurry mixing by each type of stirrer arm (namely: Two Z, TETE and Two Z – TETE) was recorded. Results obtained were analyzed using the Chi Square and the Order of Merit. There was excellent agreement between the adjusted predicted (expected) slurry mixing power (E’) and Observed slurry mixing power (O) at 5% confidence level. Empirical model was developed to predict expected slurry mixing power. The Order of Merit analysis revealed the TETE stirrer arm as the most energy efficient.

Regioselective Synthesis of 1‐Cyano‐3‐arylindolizines: Construction of Pyrroles via DDQ‐Mediated Ring Closure of Cyclopropyl Pyridines
Authors: Joshi Dirgha Raj , Kim Ikyon 
Published: July 2022

AbstractA modular approach to a wide range of 1‐cyano‐3‐(hetero)arylindolizines through aldol‐cyclopropanation‐oxidative cycloisomerization is described where DDQ was utilized for the regioselective synthesis of the pyrrole units from cyclopropyl pyridines for the first time. A key to success is regioselective oxidation of benzylic position by DDQ, which enabled us to access to one regioisomer out of two possible ones. Homo‐dimerization at the C2, C5, or C7 sites of indolizines in the presence of DDQ has been discovered for the first time as well.magnified image

ObjectiveElevated vascular risk and beta‐amyloid (Aβ) burden have been synergistically associated with cognitive decline in preclinical Alzheimer's disease (AD), although the underlying mechanisms remain unclear. We examined whether accelerated longitudinal tau accumulation mediates the vascular risk‐Aβ interaction on cognitive decline.MethodsWe included 175 cognitively unimpaired older adults (age 70.5 ± 8.0 years). Baseline vascular risk was quantified using the office‐based Framingham Heart Study general cardiovascular disease risk score (FHS‐CVD). Baseline Aβ burden was measured with Pittsburgh Compound‐B positron emission tomography (PET). Tau burden was measured longitudinally (3.6 ± 1.5 years) with Flortaucipir PET, focusing on inferior temporal cortex (ITC). Cognition was assessed longitudinally (7.0 ± 2.0 years) using the Preclinical Alzheimer's Cognitive Composite. Linear mixed effects models examined the interactive effects of baseline vascular risk and Aβ on longitudinal ITC tau. Additionally, moderated mediation was used to determine whether tau accumulation mediated the FHS‐CVD*Aβ effect on cognitive decline.ResultsWe observed a significant interaction between elevated baseline FHS‐CVD and Aβ on greater ITC tau accumulation (p = 0.004), even in individuals with Aβ burden below the conventional threshold for amyloid positivity. Examining individual vascular risk factors, we found elevated systolic blood pressure and body mass index showed independent interactions with Aβ on longitudinal tau (both p < 0.0001). ITC tau accumulation mediated 33% of the interactive association of FHS‐CVD and Aβ on cognitive decline.InterpretationVascular risks interact with subthreshold levels of Aβ to promote cognitive decline, partially by accelerating early neocortical tau accumulation. Our findings support vascular risk reduction, especially treating hypertension and obesity, to attenuate Aβ‐related tau pathology and reduce late‐life cognitive decline. ANN NEUROL 2022;92:745–755

Published: July 2022

AbstractWe report the development of bifunctional trifluoromethylsilyl reagents for selective trifluoromethylation. The newly developed reagent, Me2(CH2Cl)SiCF3, allows highly enantioselective trifluoromethylations of ketones with broad scope. Notably, by taking advantage of the chloromethyl group, a tandem synthesis of chiral trifluoromethylated oxasilacyclopentanes is developed, paving way to α‐CF3 tertiary alcohols with vicinal tertiary or quaternary stereocenters. Theoretical studies revealed the important role of nonclassical C−H⋅⋅⋅F−C interactions in stabilizing the transition state, and that the presence of the chlorine atom enhances such interactions for better enantiofacial control.

Published: July 2022

AbstractBio‐based polyurethane foam has attracted growing attention worldwide due to its advantages of environmental friendliness and wide range of raw materials. However, the stability and degradation ability of the newly prepared foams need to be further explored for their practical application. Four agricultural wastes (XS: oilseed rape straw/OS, rice straw/RS, wheat straw/WS, and corn stover/CS) liquefied polyols were used to replace petroleum polyol for preparing polyurethane foams (XSPU). These bio‐based foams were investigated by Thermogravimetric analysis (TGA), Fourier transformed infrared spectroscopy (FTIR), two dimensional correlate infrared spectroscopy (2D‐COS IR), water immersion test, soil burying test, and compression test to confirm their stability and degradation properties for applications. XSPU foams displayed excellent thermal stability with heating till to 240°C, appeared to change less than 0.3% in dry weight and contain more hydrogen bonds after immersing in water at 20°C for 14 days. The degradability of XSPU foams was significantly higher than that of petroleum polyol‐based PU foam as their soft segments were easier to be decomposed, where the weight loss of XSPU was up to 46.7% after burying in the soil at 23°C and 50% relative humidity for 250 days. The compression recovery ability of these bio‐based foams could reach approximately 98.2% after 1 ~ 3 times of compression test. Generally, XSPU foams displayed excellent thermal stability, stability in water, degradability in soil, and elastic ability, which showed potential application in fields of insulation, degradable plastic, and elastomer.

AbstractThe present work aims to develop active and biodegradable coating from polyvinyl alcohol (PVOH), agarose, and D‐glucose combined with Sonneratia ovata leaf extract (SO) for prolonging the shelf life of Grande Naine banana. In addition, the PVOH/agarose/D‐glucose/SO coating films were prepared through solvent evaporation method before applying it to banana for the purpose of characterizing vital properties required for food packaging materials. Our findings showed that the addition of SO in the polymer blend based on PVOH/agarose/D‐glucose (PAD) imparts outstanding flexibility, UV‐barrier, antioxidant, and bactericidal properties of the resultant film. It was also found that the modified coatings with SO could prolong the shelf life of bananas up to day 6th storage at 25°C. The visual appearance, development of peel color, weight loss, total soluble sugar content, and pH of banana samples confirmed that PAD‐SO coating could prevent ripening of bananas during the storage period as compared to uncoated and PAD‐coated fruits. These results suggest that PAD‐SO active coatings are a promisingly potential material for extending the shelf life of fruits.

Published: July 2022

AbstractThe structural, morphological, thermal, dielectric and electrical conductivity properties of poly(diphenylamine) (PDPA)/zinc oxide (ZnO) nanocomposites, synthesized by in‐situ chemical polymerization technique, were systematically evaluated and characterized. The ammonia (NH3) gas sensing characteristics of composites were evaluated as a function of ZnO nanoparticle concentration. The Fourier transform infrared (FTIR) spectra of composites showed the characteristic band of ZnO nanoparticles at 418 cm−1indicating an effective interaction between the polymer matrix and filler. The X‐ray diffraction (XRD) studies confirm the increased crystallinity in the PDPA structure when ZnO is incorporated. The uniform distribution of nanoparticles within the polymer matrix is confirmed by transmission electron microscopy (TEM) images. The differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) studies emphasize the shift in glass transition temperatures and enhanced thermal stability of composites relative to bare PDPA, which is further confirmed by the Coat‐Redfern method. Conductivity studies show a significant increase in magnitudes of real part of dielectric permittivity and dielectric loss tangent concerning filler content. The addition of 7 wt% ZnO nanoparticles to PDPA increases the room temperature AC conductivity from 1.058 × 10−5to 7.8 × 10−4 S/cm. Moreover, the room‐temperature NH3gas sensing property of PDPA/ZnO nanocomposites was accelerated by the addition of ZnO nanoparticles.

Published: July 2022

AbstractFlexible piezoresistive pressure sensors have great application potential in many emerging fields such as electronic skin, artificial intelligence and human healthcare. However, most of the sensors are flammable, which will easily initiate fire hazard in case of short circuit. Herein, a flame‐retardant and conductive cotton fabric (CF) was fabricated for piezoresistive pressure sensor by layer‐by‐layer (LBL) assembly of branched polyethyleneimine (b‐PEI) modified halloysite nanotubes (HNTs), phytic acid (PA) and graphene oxide (GO) and the subsequent thermal reduction of GO. The composite coating layer endowed the obtained CF with excellent flame retardancy. The limiting oxygen index of the CF reached 32.72% and the char length after vertical burning test was only 3.8 cm, attributing to the physical barrier role of the HNTs and graphene nanosheets as well as the phosphorus‐nitrogen synergism between PA and b‐PEI. The CF‐based piezoresistive pressure sensor exhibited fast and accurate response, good signal stability and fatigue resistance (3000 loading‐unloading cycles) and was able to be applied for detecting human motions including pulse beat, pronunciation and various physical activities. The preparation method in this work is simple, and the piezoresistive pressure sensor shows great application prospect in the field of flexible electronics with high safety.
