Published: July 2022

Lycosa (Araneae, Lycosidae) is a wolf spider genus typical of subtropical latitudes in the western Palearctic. Despite being erected over 200 years ago, the taxonomy of Lycosa is still unclear. Many species formerly ascribed to it are currently being moved to other genera, while new species are still being described. The species of Lycosa of the western Mediterranean basin are relatively well known, yet the Levantine region, the easternmost part of the Mediterranean basin, has not received much attention since the early 20th century. Here, we study Lycosa from the southern Levant using morphological, molecular and behavioral characteristics, to delimit the species found in this region. We describe two new species: L. hyraculus sp. nov. and L. gesserit sp. nov. We re-describe the widespread and polymorphic species, Lycosa piochardi Simon, 1876. Lycosa piochardi infraclara Strand, 1913 is synonymized with Lycosa piochardi. By adding novel data to the molecular phylogeny of Lycosa created by Planas et al. (2013) and re-analyzing it, we explore the relationship of the Levantine species to other Mediterranean species of Lycosa. We discuss habitat preferences of the two species of Lycosa. Additionally, we report the burrowing species Geolycosa vultuosa (C.L. Koch, 1838) as a new record to Israel, thus extending the distribution of this species and genus into the Levant.
A journey through interprofessional education: Students’ perspectives of teamwork in a transforming curriculum
Authors: Hendricks A , Hartman N , Olckers L 
Published: July 2022

Background. Student engagement in curricular transformation is topical at the University of Cape Town (UCT), including in its Faculty of Health Sciences (FHS). Teamwork, which is essential to contemporary interprofessional healthcare, is an objective of transformative health sciences education. This study offers a contemporary contribution from the perspective of students to earlier work on shared learning at UCT FHS.
Objectives. There is a paucity of research literature on this study’s target population. Therefore, a qualitative design was used to explore first-year health sciences students’ perceptions and experiences of teamwork within an undergraduate shared learning programme.
Methods. The primary data collection method was focus group discussion. Two additional qualitative methods, free-listing and pile-sorting, were used to expand upon data collected in the focus groups. Results were analysed thematically.
Results. The study sample (N=32) included first-year audiology, medical, occupational therapy, physiotherapy, and speech and language pathology students. The findings revealed that although their experiences of teamwork varied, students had a comprehensive perception of what teamwork entailed in their educational context. Therefore, the findings were used to generate a heuristic for teamwork learning for undergraduate health sciences students.
Conclusion. The study positions students to contribute tangibly to the curricular transformation process at their university. Students’ perspectives of teamwork may be useful in the future design and delivery of entry-level interprofessional courses aiming to instil teamwork skills.

La economía colaborativa relacionada con el transporte de personas, el alojamiento, la comida y la vivencia de experiencias muestra gran relevancia en el sector del turismo. El objetivo de esta investigación es valorar cuatro plataformas de economía colaborativa (Airbnb, Blablacar, Eatwith y Trip4Real) en base a la valor de uso, la confianza, la utilidad de leer y hacer comentarios, e intención de uso y de recomendar. En la valoración de las plataformas se analiza la influencia del sexo, la edad y la forma en que los participantes del estudio acceden a las plataformas. Metodológicamente, se aplica un modelo de análisis de variancia multivariado, manova, en un diseño factorial 2x2x2x4 (Generación x Grupo x Sexo x Plataforma) para analizar los efectos principales y las interacciones entre factores. El tipo de muestreo es no probabilístico, intencional, basado en cuotas de edad y sexo. La muestra final fue de 222 participantes (n = 222). La plataforma Trip4Real, relacionada con el turismo experiencial, es la que despierta el mayor grado de interés en los participantes del estudio. El factor con más influencia sobre las distintas valoraciones ha sido el Grupo, corroborando la importancia de acercarse a los distintos servicios analizados de la economía colaborativa desde una perspectiva real o necesidad creada. Por otra parte, los jóvenes o millennials son más receptivos, muestran más confianza ante las plataformas presentadas y perciben más útiles los comentarios online emitidos.
Mercados sociales e intercooperación en la Economía Social y Solidaria como vía para recuperar soberanías: el caso del Mercado Social de Euskadi
Authors: Arrillaga Márquez Pablo , Etxezarreta Etxarri Enekoitz 
Published: July 2022

En los últimos años la Economía Social y Solidaria ha encontrado en los mercados sociales una estrategia para su crecimiento y fortalecimiento. Los mercados sociales, entendidos como espacios donde aglutinar agentes, experiencias, recursos y aprendizajes en torno a unas relaciones de producción, distribución, financiación y consumo basadas en la justicia social y ambiental, la reciprocidad y la ayuda mutua, son, además, experiencias que permiten democratizar y acercar a la ciudadanía el control de los procesos productivos que se articulan en torno a ellos. En este artículo se parte de la hipótesis de que el clima para la intercooperación que estos espacios facilitan, permite avanzar, a su vez, en la recuperación de soberanías sectoriales en manos de la ciudadanía. Para ello, se han tomado como referencia algunas experiencias destacables del Mercado Social de Euskadi en las que, mediante la intercooperación entre varias entidades, se ha podido avanzar en torno a la soberanía alimentaria, energética y financiera.
Los derechos sindicales en las cooperativas: un estudio de su regulación en la negociación colectiva
Authors: Canalda Criado Sergio 
Published: July 2022

Las cooperativas representan un escenario idóneo para la expresión de los valores democráticos. Con relación a ello, las organizaciones sindicales están llamadas a desempeñar un papel fundamental en nuestro ordenamiento jurídico a través de la articulación de la defensa de los intereses de los trabajadores, dentro y fuera de las empresas. La confluencia de la acción sindical y los principios democráticos que rigen las cooperativas es el objeto de esta investigación. Concretamente, en este trabajo se analiza la negociación colectiva desarrollada en las sociedades cooperativas como ejemplo de esa confluencia. El análisis toma en consideración, por un lado, las características de los convenios colectivos y los sujetos representantes de los trabajadores que los han negociado y, por otro lado, el contenido de los convenios que regula derechos sindicales.El análisis de la muestra de convenios colectivos permite mostrar un mapa completo de la negociación colectiva que se produce en las cooperativas atendiendo al ámbito funcional, territorial y personal, así como el tipo de sujeto representante de los trabajadores y las organizaciones sindicales participantes. Además, el trabajo permite detectar que los convenios colectivos que regulan derechos sindicales no sólo mejoran las competencias y las garantías protegidas legalmente, sino que también garantizan un efectivo ejercicio del derecho de libertad sindical más allá de los representantes sindicales.

Authors: Pérez Colombia , Hunt Abigail , Binat Sarwar Moizza 
Published: July 2022

The article gives an account of the result of the research developed in response to the call made by the International Labour Organization (ILO) and the Open Society Foundations (OSF) in 2021 to carry out a project that would identify the potential of the link between unions and cooperatives to organize workers in the informal economy in African and Latin American countries. Researchers from ODI, London, with the collaboration of researchers and practitioners from Brazil, Colombia, Ghana, Kenya and Uganda, identified and documented partnership examples through which to shed light development processes, identify learning on successes and challenges, and inform recommendations for future support. A country case study of Colombia is provided to illustrate the variety, complexity and possibilities of the topic studied. Three nascent partnership experiences, linked in different ways to the social and solidarity economy, demonstrate the potential of this approach to promote fair trade, responsible consumption and local markets, boost entrepreneurship and create decent working conditions for workers who traditionally face informality.

AbstractWith the utilization of magnetic resonance (MR) imaging in radiotherapy increasing, routine quality assurance (QA) of these systems is necessary. The assessment of geometric distortion in images used for radiotherapy treatment planning needs to be quantified and monitored over time. This work presents an adaptable methodology for performing routine QA for systematic MRI geometric distortion. A software tool and compatible protocol (designed to work with any CT and MR compatible phantom on any scanner) were developed to quantify geometric distortion via deformable image registration. The MR image is deformed to the CT, generating a deformation field, which is sampled, quantifying geometric distortion as a function of distance from scanner isocenter. Configurability of the QA tool was tested, and results compared to those provided from commercial solutions. Registration accuracy was investigated by repeating the deformable registration step on the initial deformed MR image to define regions with residual distortions. The geometric distortion of four clinical systems was quantified using the customisable QA method presented. Maximum measured distortions varied from 2.2 to 19.4 mm (image parameter and sampling volume dependent). The workflow was successfully customized for different phantom configurations and volunteer imaging studies. Comparison to a vendor supplied solution showed good agreement in regions where the two procedures were sampling the same imaging volume. On a large field of view phantom across various scanners, the QA tool accurately quantified geometric distortions within 17–22 cm from scanner isocenter. Beyond these regions, the geometric integrity of images in clinical applications should be considered with a higher degree of uncertainty due to increased gradient nonlinearity and B0 inhomogeneity. This tool has been successfully integrated into routine QA of the MRI scanner utilized for radiotherapy within our department. It enables any low susceptibility MR‐CT compatible phantom to quantify the geometric distortion on any MRI scanner with a configurable, user friendly interface for ease of use and consistency in data collection and analysis.

AbstractObjectiveIntracellular signaling networks rely on proper membrane organization to control an array of cellular processes such as metabolism, proliferation, apoptosis, and macroautophagy in eukaryotic cells and organisms. Phosphatidylinositol 4‐phosphate (PI4P) emerged as an essential regulatory lipid within organelle membranes that defines their lipid composition and signaling properties. PI4P is generated by four distinct phosphatidylinositol 4‐kinases (PI4K) in mammalian cells: PI4KA, PI4KB, PI4K2A, PI4K2B. Animal models and human genetic studies suggest vital roles of PI4K enzymes in development and function of various organs, including the nervous system. Bi‐allelic variants in PI4KA were recently associated with neurodevelopmental disorders (NDD), brain malformations, leukodystrophy, primary immunodeficiency, and inflammatory bowel disease. Here, we describe patients from two unrelated consanguineous families with PI4K2A deficiency and functionally explored the pathogenic mechanism.MethodsTwo patients with PI4K2A deficiency were identified by exome sequencing, presenting with developmental and epileptic‐dyskinetic encephalopathy. Neuroimaging showed corpus callosum dysgenesis, diffuse white matter volume loss, and hypoplastic vermis. In addition to NDD, we observed recurrent infections and death at toddler age. We further explored identified variants with cellular assays.ResultsThis clinical presentation overlaps with what was previously reported in two affected siblings with homozygous nonsense PI4K2A variant. Cellular studies analyzing these human variants confirmed their deleterious effect on PI4K2A activity and, together with the central role of PI4K2A in Rab7‐associated vesicular trafficking, establish a link between late endosome‐lysosome defects and NDD.InterpretationOur study establishes the genotype–phenotype spectrum of PI4K‐associated NDD and highlights several commonalities with other innate errors of intracellular trafficking.

AbstractMultifunctional sequential targeted delivery system is developed as an efficient therapeutic strategy against malignant tumors with selective accumulation and minimal systemic drug absorption. The therapeutic system is comprised of microfluidized dextran microgels encapsulating cisplatin/superparamagnetic iron oxide nanoparticles (SPIONs)‐loaded trilaurin‐based lipid nanoparticles (LNPs). The microgel system is imparted hierarchically dual targeting via dextran and folic acid (FA) residues, leading to increases both in retention of the microgels in colon and in cellular uptake of the therapeutic LNPs by colon cancer cells while being used for oral therapeutic delivery. Encapsulation of the therapeutic LNPs into dextran microgels attained by microfluidized crosslinking reaction reduces gastrointestinal adhesion and prevents the FA‐modified LNPs from cellular transport by proton‐coupled FA transporters in small intestine during their oral delivery to colon. Upon enzymatic degradation of the dextran microgels by dextranase present exclusively in colon, LNPs thus released become more recognizable and readily internalized by FA receptor‐overexpressing colon cancer cells. The combined chemo/magnetothermal therapeutic effect of dual targeted lipid nanoparticle‐loaded microgels from entrapped lipidized cisplatin and alternating magnetic field‐treated SPIONs significantly inhibits tumor growth and suppresses metastatic peritoneal carcinomatosis in orthotopic colon cancer‐bearing mice.

AbstractRecent advances in supercapacitive pressure sensors based on iontronic film have a significant capacitive response and a low detection limit due to their large capacitance change resulting from electrical double layer (EDL) and these pressure sensors are used to detect a wide range of pressure with high resolution for various applications such as prosthesis, wearable devices, and robotics. Thus, the enhancements to the EDL capacitive response are significantly important challenges for advanced applications with outstanding performances. Herein, an ultra‐sensitive and quick‐responsive hybrid‐supercapacitive iontronic pressure sensor using a novel sensing mechanism and facile fabrication technique is reported to overcome the limitations of the existing iontronic pressure sensors. As a sensing material, conductive polymer and carbon nanotube are incorporated into the iontronic film, as pseudo‐ and EDL‐capacitive material, respectively. Moreover, vinyl silica nanoparticle (VSNP) is used to decrease the recovery time by making the iontronic film quick‐response. The developed hybrid‐supercapacitive pressure sensor exhibited an ultra‐high sensitivity of 301.5 kPa−1over a wide pressure range of up to 63.3 kPa along with a fast recovery time of ≈32 ms. It is believed that the proposed hybrid‐supercapacitive mechanism in iontronic film will significantly enhance the performance of conventional iontronic pressure sensors.
Grating‐Structured Freestanding Triboelectric Nanogenerator for Self‐Powered Acceleration Sensing in Real Time

Published: July 2022

AbstractAcceleration sensors have wide applications in earthquake warning, human motion recognition, vehicle restraint system, etc. However, the existing commercial acceleration sensors have some limitations on needing an external power supply, high fabrication cost, and small signal when self‐powered. Here a grating‐structured freestanding triboelectric nanogenerator (GF‐TENG) capable of sensing displacements, velocities, and accelerations in real‐time is presented with self‐powered, low cost, and sufficiently large signal. The slider with grating‐structured electrodes of GF‐TENG sliding over the stator with another grating‐structured electrode generates the periodic open‐circuit voltage due to electrostatic induction. By recognizing the shape of open‐circuit voltage, it could sense the acceleration in real time even at scales down to hundred microns through systematic optimization of simulations and experiments. Furthermore, the acceleration sensing range could be expanded to the desired ranges, such as 5.0 to 45.0 m s–2, by assembling springs and GF‐TENG into a grating‐structured TENG‐based acceleration sensor (GTAS). Moreover, GTAS is demonstrated to sense the vehicle motion and be a part of the vehicle restraint system on a model car. This work reports a new self‐powered acceleration sensor with sufficiently large outputs for real‐time motion sensing and collision detection, which could be further applicated for robotics and human motion recognition.
Price expectations, risk aversion, and choice of sales methods for large‐scale farmers under incomplete market conditions
Authors: Peng Peng , Xu Zhigang 
Published: July 2022

AbstractLarge‐scale farmers' sales methods and prices are crucial for them to realize their production value. In this study, we consider conditions that involve incomplete insurance, futures, and product markets to construct a sales decision‐making analysis framework for large‐scale farmers and to reveal the influence mechanism of different sales methods. We empirically examine data from field surveys and subjective preference experiments involving 373 large‐scale grain farmers in four provinces in China. The results reveal that large‐scale farmers' ability to anticipate prices and their degree of risk aversion are important for their choices of sales methods because of the incomplete insurance, futures, and product markets in developing countries. Price expectations reflect farmers' judgments of future price trends. Therefore, large‐scale farmers who anticipate an increase in grain prices will choose to postpone grain sales to potentially maximize profits. The degree of risk aversion determines whether farmers will sell several times to avoid normalized price volatilities. Risk‐averse large‐scale farmers will choose a multiperiod sales method, while risk‐loving ones will choose a single‐period delayed sales method.
