Authors: Bustamante Salazar Alina Marcela 
Published: April 2019

En los últimos años ha habido un creciente interés en estudiar la relación entre la responsabilidad social y la gestión humana dando origen a la gestión humana socialmente responsable. El objetivo de esta investigación es conceptualizar la gestión humana socialmente responsable en el contexto de las cooperativas de trabajo asociado colombianas, desde una perspectiva que integra el enfoque de las capacidades de Amartya Sen y los principios cooperativos, para comprender cómo las prácticas de gestión humana desarrollan diferentes capacidades de los asociados. Para lograr este propósito se realizó una investigación de enfoque cualitativo, basado en el estudio de casos múltiple y la teoría fundamentada. A partir de los resultados de la investigación, la gestión humana socialmente responsable en las cooperativas de trabajo asociado se define como un conjunto de prácticas, fundamentadas en los principios cooperativos, que están orientadas a desarrollar las capacidades de agencia, de bienestar y de solidaridad de los asociados, a través de la información, la formación, la participación, las condiciones de trabajo, la salud y la seguridad laboral, la igualdad de oportunidades y el balance trabajo-familia, para empoderarlos como trabajadores, propietarios y gestores de la cooperativa; proporcionando oportunidades laborales, económicas y sociales que contribuyan a su bienestar y les permita ser y hacer lo que consideran valioso para sus vidas; y de proyección a la comunidad a través de la información y la formación. Para lograr este propósito es necesario tener en cuenta las condiciones personales, organizacionales y del entorno externo que afectan estas prácticas, el cumplimiento de los principios cooperativos y el desarrollo de las capacidades de los asociados.

Published: April 2019

Una característica diferenciadora de la economía colaborativa es el uso de las nuevas tecnologías por diferentes agentes que persiguen un objetivo común. Esta revolución digital plantea un reto a las organizaciones de la economía social.El objetivo de este trabajo es analizar cómo el cooperativismo de plataforma puede ser una vía adecuada para llevar a cabo la mejora del bienestar social en barrios vulnerables. Con el fin de promover la renovación y mejora de los barrios es necesario una participación activa de los ciudadanos y de la administración pública; de hecho, uno de los elementos claves en la obtención de la mejora de la calidad de vida es la implicación de los residentes que, en muchas ocasiones, son los que proponen los cambios y la renovación en sus barrios con deficiencias importantes de habitabilidad y consumo energético, problemas de accesibilidad y carencia de servicios. Hace falta, pues, recuperar la ciudad consolidada a través de la rehabilitación y regeneración urbana. El cooperativismo de plataforma puede facilitar la participación pública de los distintos actores intervinientes en los procesos de rehabilitación urbana como residentes (a título individual o asociados), administraciones públicas, cooperativas y otros usuarios, promoviendo que se involucren de manera activa en el diseño y seguimiento de los proyectos de regeneración urbana, a través del uso de la plataforma digital.El cooperativismo de plataforma puede ser el nexo de unión entre los valores cooperativos y la revolución digital encaminados a promover la mejora del bienestar de la sociedad.

Published: April 2019

El sector financiero en general, y el bancario en particular, se han caracterizado habitualmente por ser innovadores en la incorporación de la tecnología a sus procesos y servicios. Sin embargo, por primera vez en su historia, la tecnología está originando modos de desintermediación financiera y de capacidad de aportación de servicios que nacen en empresas tecnológicas y no en entidades financieras. La disrupción de las pequeñas empresas fintech; así como la innovación en servicios financieros ofrecidos por los gigantes tecnológicos, parecen amenazar el modelo de negocio tradicional de la banca. En este contexto, la banca cooperativa no es ajena a este fenómeno y vive su propia transformación digital, tanto por la demanda de sus socios y clientes, como por la necesidad de competir frente a esos nuevos actores financieros. Su tradicional arraigo territorial y el conocimiento más personalizado de sus socios y clientes deben hacerse ahora compatibles con los planteamientos de una nueva sociedad digital. Por ello, en este trabajo se ha analizado cuál es la percepción de las cooperativas de crédito españolas sobre la transformación digital, lo que ha arrojado interesantes resultados como: la reconocida necesidad de mejorar en la digitalización de sus procesos internos y externos; su percepción sobre la amenaza proveniente de las grandes empresas tecnológicas; las diferencias en lo que respecta a la digitalización de los socios y usuarios cuando cambia la dimensión de las entidades; así como su papel en la educación financierodigital de su base societaria y de usuarios.

Published: April 2019

AbstractDNA origami strategy has greatly promoted the development of DNA nanotechnology as it can construct delicate 2D/3D nanostructures. The current method to prepare DNA origami is through a woven approach to fix a long strand of DNA into certain shapes. This article describes a novel strategy to fold the same 2D DNA sheet into multiple complex structures driven by introducing hydrophobic interaction. The pathway of the folding process can be adjusted by tuning the distribution and chronic order of cholesterol, resulting in different complicated structures. This method is proven efficient for constructing variable nanostructures based on the same DNA origami sheet, and termed as origami+. This work represents a new strategy in DNA nanotechnology and will improve the ability to manipulate objects at nanoscale.

AbstractThe ability to control nanoparticle size, concentration, and distribution in epitaxial nanocomposite films has been a formidable challenge in the synthesis of nanostructured composite materials. Here, a novel 3D super‐nanocomposite (3D‐sNC) architecture is successfully demonstrated by integrating superlattice and vertically aligned nanocomposite structures. In the 3D‐sNC architecture, the feature size and distribution of the nanocylinders such as the height/lateral dimension and the vertical/lateral spacing of nanocylinders can be precisely controlled. The microstructure parameters such as nanocylinder height and spacing modulated interfacial area control the lattice strain, which further tunes the magnetotransport property. These results demonstrate that 3D‐sNC is a simple and yet effective architecture to achieve controlled functionalities via the precise control of nanocylinder size, spacing, concentration, and distribution. Such a 3D‐sNC structure can be used to design advanced nanostructures with desired physical properties for a variety of material systems.

Published: April 2019

AbstractFor commercial applications, it is a challenge to find suitable and low‐cost hole‐transporting material (HTM) in perovskite solar cells (PSCs), where high efficiency spiro‐OMeTAD and PTAA are expensive. A HTM based on 9,9‐dihexyl‐9H‐fluorene andN,N‐di‐p‐methylthiophenylamine (denoted as FMT) is designed and synthesized. High‐yield FMT with a linear structure is synthesized in two steps. The dopant‐free FMT‐based planar p‐i‐n perovskite solar cells (pp‐PSCs) exhibit a high power conversion efficiency (PCE) of 19.06%, which is among the highest PCEs reported for the pp‐PSCs based on organic HTM. For comparison, a PEDOT:PSS HTM‐based pp‐PSC is fabricated under the same conditions, and its PCE is found to be 13.9%.
Recent Development of Printed Micro‐Supercapacitors: Printable Materials, Printing Technologies, and Perspectives
Authors: Li Hongpeng , Liang Jiajie 
Published: April 2019

AbstractThe rapid progression of portable and wearable electronics has necessitated the development of high‐performing, miniaturized energy‐storage devices with flexible form factors and high energy and power delivery. Printed micro‐supercapacitors (MSCs), with in‐plane interdigital configurations, is touted as a promising choice to fulfill these requirements. New printing technologies can assemble MSCs with fiscal and environmental benefits, large form factors, and at high throughputs, qualities not afforded with conventional microfabrication technologies. Here, recent progress in the preparation of functional ink systems for wearable MSCs, encompassing electrode materials, conductor materials, and electrolytes, is presented. First, a comprehensive background of the fundamentals of printing technology is introduced, with discussions focusing on methods of improving ink functionality while simultaneously retaining good printability. Second, various printing techniques to ensure manufacturable scaling of wearable MSCs with high areal electrochemical performance and small footprint are explored. Within the scope of these two topics, various issues that hinder the full materialization of widespread adoption of printed MSC and next steps to overcome these issues are discussed. Further deep dives in scientific and technical challenges are also presented, including limited functionality of the inks, low printing resolution, overlay accuracy, and complex encapsulation.
PEG‐Lipid Post Insertion into Drug Delivery Liposomes Quantified at the Single Liposome Level
Authors: Eliasen Rasmus , Andresen Thomas L. , Larsen Jannik B. 
Published: April 2019

AbstractLiposomal drug delivery systems are designed to avoid the body's natural clearance machinery and are typically achieved by incorporation lipid‐anchored poly(ethylene glycol) (PEG) polymers. When preparing such liposomes it is intrinsically assumed that all available PEG‐lipid is incorporated evenly into every liposome of a preparation, however this assumption remains unchallenged. Thus, a quantitative understanding of how PEG‐lipid incorporation conditions affect the PEG density on individual liposomes can provide novel insights on how to optimize an important parameter of liposomal circulation kinetics and therapeutic efficacy. Here a sensitive fluorescence‐based single liposome assay is employed that allows, for the first time, the quantification of the PEG‐lipid density on individual liposomes. The assay is used to demonstrate that incubation time and temperature, liposome membrane lipid saturation state and PEG anchoring moiety all affect the effective PEG surface density. Furthermore, the unique ability of the assay to investigate single liposomes within the ensemble, allows to quantify significant variations in PEG surface density between individual liposomes. Thus, the assay provides crucial insights on how to improve both the overall PEG surface density and reduce the liposome‐to‐liposome variation, facilitating the design and development of more uniform, controllable, and efficacious PEG‐lipid containing liposomal drug delivery systems.
Giant retroperitoneal lipoma presenting as abdominal protrusion: One case report and review of literature
Authors: Chen Yung‐Hung , Chen Ming‐Jen , Lin Han‐Jung 
Published: April 2019

AbstractLipomas are benign tumors of mature adipocytes, which are commonly located in the subdermal tissue of the trunk or extremities. Deep‐seated lipomas, especially originating from the retroperitoneal space, are extremely rare. We present the case of a 57‐year‐old man with a giant retroperitoneal lipoma but without impaired gastrointestinal (GI) function. This patient visited the GI outpatient clinic for progressively distended abdomen in the preceding months. The patient denied experiencing any nausea, loss of appetite, abdominal pain, and change of bowel habits. Physical examination demonstrated a soft, nontender protrusion in the abdomen without guarding. Further analysis via dynamic liver computed tomography scan indicated a large, fat‐attenuated, mass‐like lesion in the left upper abdomen. In order to rule out malignant fat‐containing retroperitoneal masses, the patient underwent resection of the retroperitoneal and intra‐abdominal tumor. It is quite important to analyze the characteristics of the tumor accurately in order to make subsequent decisions on how to proceed with the surgery.

AbstractAlmost all primates experience seasonal fluctuations in the availability of key food sources. However, the degree to which this fluctuation impacts foraging behavior varies considerably. Eastern chimpanzees (Pan troglodytes schweinfurthii) in Nyungwe National Park, Rwanda, live in a montane forest environment characterized by lower primary productivity and resource diversity than low‐elevation forests. Little is known about chimpanzee feeding ecology in montane forests, and research to date predominantly relies on indirect methods such as fecal analyses. This study is the first to use mostly observational data to examine how seasonal food availability impacts the feeding ecology of montane forest chimpanzees. We examine seasonal changes in chimpanzee diet and fallback foods (FBFs) using instantaneous scan samples and fecal analyses, supported by inspection of feeding remains. Chimpanzee fruit abundance peaked during the major dry season, with a consequent change in chimpanzee diet reflecting the abundance and diversity of key fruit species. Terrestrial herbaceous vegetation was consumed throughout the year and is defined as a “filler” FBF. In contrast to studies conducted in lower‐elevation chimpanzee sites, figs (especiallyFicus lutea) were preferred resources, flowers were consumed at seasonally high rates and the proportion of non‐fig fruits in the diet were relatively low in the current study. These divergences likely result from the comparatively low environmental diversity and productivity in higher‐elevation environments.

Published: April 2019

BackgroundNowadays, it is getting easier to search information about helium‐assisted suicide online. Therefore, healthcare professionals must understand helium‐associated medical conditions.Case PresentationA 27‐year‐old man was found with his head covered with a bag connected to a helium tank. Hyperbaric oxygen therapy was not given because his head computed tomography showed no cerebral vasculature air embolism and there was no obvious limb paralysis. The diagnosis was impaired consciousness with hypoxic encephalopathy; he needed mechanical ventilation for 2 days. He was discharged after intelligence tests with no obvious higher brain dysfunction.ConclusionWe successfully treated a patient with hypoxic encephalopathy due to helium inhalation. Our analysis suggests that the pathophysiology and appropriate intervention of helium intoxication might be different according to the devices used.
Unprecedented Bonding Situation in Viable E2(NHBMe)2(E=Be, Mg; NHBMe=(HCNMe)2B) Complexes: Neutral E2Forms a Single E−E Covalent Bond

Published: April 2019

AbstractIs it possible to facilitate the formation of a genuine Be−Be or Mg−Mg single bond for the E2species while it is in its neutral state? So far, (NHCR)Be−Be(NHCR) (R=H, Me, Ph) have been reported where Be2is in1Δgexcited state imposing a formal Be−Be bond order of two. Herein, we present the formation of a single E−E (E=Be, Mg) covalent bond in E2(NHBMe)2(E=Be, Mg; NHBMe=(HCNMe)2B) complexes where E2is in3∑u+excited state having (nσg+)2(nσu+)1((n+1)σg+)1(n=2 for Be andn=4 for Mg) valence electron configuration and it forms electron‐shared bonding with two NHBMeradicals. The effects of bonding with nσu+and (n+1)σg+orbitals will cancel each other, providing the former E−E bond order as one. Be2(NHBMe)2complex is thermochemically stable with respect to possible dissociation channels at room temperature, whereas the two exergonic channels, Mg2(NHBMe)2→ Mg + Mg(NHBMe)2and Mg2(NHBMe)2→ Mg2+ (NHBMe)2, are kinetically inhibited by a free energy barrier of 15.7 and 18.7 kcal mol−1, respectively, which would likely to be further enhanced in cases of bulkier substituents attached to the NHB ligands. Therefore, the title complexes are first viable systems which feature a neutral E2moiety with a single E−E covalent bond.

Authors: Shi Renyi , Hu Xile 
Published: April 2019

AbstractKetones are an important class of molecules in synthetic and medicinal chemistry. Rapid and modular synthesis of ketones remains in high demand. Described here is a nickel‐catalyzed three‐component reductive carbonylation method for the synthesis of dialkyl ketones. A wide range of both symmetric and asymmetric dialkyl ketones can be accessed from alkyl halides and a safe CO source, ethyl chloroformate. The approach offers complementary substrate scope to existing carbonylation methods while avoiding the use of either toxic CO or metal carbonyl reagents.

AbstractLigand conformational entropy plays an important role in carbohydrate recognition events. Glycans are characterized by intrinsic flexibility around the glycosidic linkages, thus in most cases, loss of conformational entropy of the sugar upon complex formation strongly affects the entropy of the binding process. By employing a multidisciplinary approach combining structural, conformational, binding energy, and kinetic information, we investigated the role of conformational entropy in the recognition of the histo blood‐group antigens A and B by human galectin‐3, a lectin of biomedical interest. We show that these rigid natural antigens are pre‐organized ligands for hGal‐3, and that restriction of the conformational flexibility by the branched fucose (Fuc) residue modulates the thermodynamics and kinetics of the binding process. These results highlight the importance of glycan flexibility and provide inspiration for the design of high‐affinity ligands as antagonists for lectins.
