Disability in the workplace: corporate strategies in a discourse analytical perspective
Authors: Francesca Santulli  
Published: October 2017

Against the background of the UN Convention on the Rights of Persons with Disabilities, the paper focuses on disability policies in the workplace, taking into consideration the position of the International Labour Organization (ILO) and of its permanent Secretariat, the International Labour Office. The study is set in the discourse analytical tradition and analyses two documents: the ILO Disability Inclusion Strategy and Action Plan and the working paper Disability in the Workplace: Company Practices. The former outlines general principles and illustrates objectives and strategies of the Agency; the latter is a collection of profiles describing the disability policy of 25 major companies. The investigation combines a qualitative approach with quantitative analysis, to single out relevant language features. In particular, the content structure of the companies’ profiles is described and analysed, while the fundamental lexicon of disability issues is examined in context. Special attention is given to the use of narrative and/or argumentation and to companies’ policy declarations. By adopting this multi-dimensional approach, it is possible to shed light on the discursive ambiguities of the texts, which overtly adopt the UN Convention principles, but do not systematically and consistently comply with the new paradigm of disability in their communication effort.
Framom kroppslege stengsel. Refleksjonar over ei sjukepleieerfaring frå praksiskvardagen

Published: October 2017

In this essay we reflect on nurse Jenny`s narrative to draw attention to how different interpretations of patients bodily expressions may have impact for the help patients receives. The purpose of discussion is how nurses may be able to understand their own reactions, and to improve their ability to meet and support the patient even if the patient`s bodily expressions may arouse discomfort and emotional resistance. In her meeting with the patient, the nurse can open up or close the space for communication. How can the nurse’s way of being support the patients many different ways of emotionally expressions? This depends on systems, routines and the nurse`s own vulnerability and understanding of life experiences. And it may be connected to the nurse’s ability to open up for and respect the experiences and meaning in a patient`s lived and present life.

Published: October 2017

AbstractTo investigate the oceanic lithosphere formation and early seafloor spreading history of the North Atlantic Ocean, we examine multiscale magnetic anomaly data from the Jurassic/Early Cretaceous age Eastern North American Margin (ENAM) between 31 and 40°N. We integrate newly acquired sea surface magnetic anomaly and seismic reflection data with publicly available aeromagnetic and composite magnetic anomaly grids, satellite‐derived gravity anomaly, and satellite‐derived and shipboard bathymetry data. We evaluate these data sets to (1) refine magnetic anomaly correlations throughout the ENAM and assign updated ages and chron numbers to M0–M25 and eight pre‐M25 anomalies; (2) identify five correlatable magnetic anomalies between the East Coast Magnetic Anomaly (ECMA) and Blake Spur Magnetic Anomaly (BSMA), which may document the earliest Atlantic seafloor spreading or synrift magmatism; (3) suggest preexisting margin structure and rifting segmentation may have influenced the seafloor spreading regimes in the Atlantic Jurassic Quiet Zone (JQZ); (4) suggest that, if the BSMA source is oceanic crust, the BSMA may be M series magnetic anomaly M42 (~168.5 Ma); (5) examine the along and across margin variation in seafloor spreading rates and spreading center orientations from the BSMA to M25, suggesting asymmetric crustal accretion accommodated the straightening of the ridge from the bend in the ECMA to the more linear M25; and (6) observe anomalously high‐amplitude magnetic anomalies near the Hudson Fan, which may be related to a short‐lived propagating rift segment that could have helped accommodate the crustal alignment during the early Atlantic opening.
The Impact of Atmospheric Modeling Errors on GRACE Estimates of Mass Loss in Greenland and Antarctica
Authors: Hardy Ryan A. , Nerem R. Steven , Wiese David N. 
Published: October 2017

AbstractSystematic errors in Gravity Recovery and Climate Experiment (GRACE) monthly mass estimates over the Greenland and Antarctic ice sheets can originate from low‐frequency biases in the European Centre for Medium‐Range Weather Forecasts (ECMWF) Operational Analysis model, the atmospheric component of the Atmospheric and Ocean Dealising Level‐1B (AOD1B) product used to forward model atmospheric and ocean gravity signals in GRACE processing. These biases are revealed in differences in surface pressure between the ECMWF Operational Analysis model, state‐of‐the‐art reanalyses, and in situ surface pressure measurements. While some of these errors are attributable to well‐understood discrete model changes and have published corrections, we examine errors these corrections do not address. We compare multiple models and in situ data in Antarctica and Greenland to determine which models have the most skill relative to monthly averages of the dealiasing model. We also evaluate linear combinations of these models and synthetic pressure fields generated from direct interpolation of pressure observations. These models consistently reveal drifts in the dealiasing model that cause the acceleration of Antarctica's mass loss between April 2002 and August 2016 to be underestimated by approximately 4 Gt yr−2. We find similar results after attempting to solve the inverse problem, recovering pressure biases directly from the GRACE Jet Propulsion Laboratory RL05.1 M mascon solutions. Over Greenland, we find a 2 Gt yr−1 bias in mass trend. While our analysis focuses on errors in Release 05 of AOD1B, we also evaluate the new AOD1B RL06 product. We find that this new product mitigates some of the aforementioned biases.
The Plumbing System Feeding the Lusi Eruption Revealed by Ambient Noise Tomography

Published: October 2017

AbstractLusi is a sediment‐hosted hydrothermal system featuring clastic‐dominated geyser‐like eruption behavior in East Java, Indonesia. We use 10 months of ambient seismic noise cross correlations from 30 temporary seismic stations to obtain a 3‐D model of shear wave velocity anomalies beneath Lusi, the neighboring Arjuno‐Welirang volcanic complex, and the Watukosek fault system connecting the two. Our work reveals a hydrothermal plume, rooted at a minimum 6 km depth that reaches the surface at the Lusi site. Furthermore, the inversion shows that this vertical anomaly is connected to the adjacent volcanic complex through a narrow (~3 km wide) low velocity corridor slicing the survey area at a depth of ~4–6 km. The NE‐SW direction of this elongated zone matches the strike of the Watukosek fault system. Distinct magmatic chambers are also inferred below the active volcanoes. The large‐scale tomography features an exceptional example of a subsurface connection between a volcanic complex and a solitary erupting hydrothermal system hosted in a hydrocarbon‐rich back‐arc sedimentary basin. These results are consistent with a scenario where deep‐seated fluids (e.g., magmas and released hydrothermal fluids) flow along a region of enhanced transmissivity (i.e., the Watukosek fault system damage zone) from the volcanic arc toward the back arc basin where Lusi resides. The triggered metamorphic reactions occurring at depth in the organic‐rich sediments generated significant overpressure and fluid upwelling that is today released at the spectacular Lusi eruption site.

Published: October 2017

AbstractThe Andes between 28° and 30°S represent a transition between the Puna‐Altiplano Plateau and the Frontal/Principal Cordillera fold‐and‐thrust belts to the south. While significant early Cenozoic deformation documented in the Andean Plateau, deciphering the early episodes of deformation during Andean mountain building in the transition area is largely unstudied. Apatite fission track (AFT) and (U‐Th‐Sm)/He (AHe) thermochronology from a vertical and a horizontal transect reveal the exhumation history of the High Andes at 30°S, an area at the heart of this major transition. Interpretation of the age‐elevation profile, combined with inverse thermal modeling, indicates that the onset of rapid cooling was underway by ~35 Ma, followed by a significant decrease in cooling rate at ~30–25 Ma. AFT thermal models also reveal a second episode of rapid cooling in the early Miocene (~18 Ma) related to rock exhumation to its present position. Low exhumation between the rapid cooling events allowed for the development of a partial annealing zone. We interpret the observed Eocene rapid exhumation as the product of a previously unrecognized compressive event in this part of the Andes that reflects a southern extension of Eocene orogenesis recognized in the Puna/Altiplano. Renewed early‐Miocene exhumation indicates that the late Cenozoic compressional stresses responsible for the main phase of uplift of the South Central Andes also impacted the core of the range in this transitional sector. The major episode of Eocene exhumation suggests the creation of significant topographic relief in the High Andes earlier than previously thought.

Published: October 2017

SummaryThere is minimal research on metacognition in alcohol‐intoxicated participants. Study 1 examined metacognition across sober, intoxicated, and placebo groups, with the intoxicated group's breath alcohol concentration reaching 0.074 g/210 L on average immediately prior to the metacognition task. Participants answered cued recall general knowledge questions and provided confidence ratings and feeling‐of‐knowing judgments. They then completed a recognition (i.e., multiple choice) version of the same task, indicating an answer and a confidence rating for each question. Findings suggest that metacognitive accuracy generally did not vary across intoxication levels, although the control group's retrospective confidence judgments better discriminated between accurate and inaccurate responses than the alcohol groups in the recognition task. Study 2 surveyed academic psychologists about their expectations regarding the relation between alcohol and metacognition. Study 1's results were counter to their expectations, as respondents generally predicted a relation would be present. We discuss the implications for alcohol and memory.Copyright © 2017 John Wiley & Sons, Ltd.
A New Design Strategy for Efficient Thermally Activated Delayed Fluorescence Organic Emitters: From Twisted to Planar Structures

Published: October 2017

AbstractIn the traditional molecular design of thermally activated delayed fluorescence (TADF) emitters composed of electron‐donor and electron‐acceptor moieties, achieving a small singlet–triplet energy gap (ΔEST) in strongly twisted structures usually translates into a small fluorescence oscillator strength, which can significantly decrease the emission quantum yield and limit efficiency in organic light‐emitting diode devices. Here, based on the results of quantum‐chemical calculations on TADF emitters composed of carbazole donor and 2,4,6‐triphenyl‐1,3,5‐triazine acceptor moieties, a new strategy is proposed for the molecular design of efficient TADF emitters that combine a small ΔEST with a large fluorescence oscillator strength. Since this strategy goes beyond the traditional framework of structurally twisted, charge‐transfer type emitters, importantly, it opens the way for coplanar molecules to be efficient TADF emitters. Here, a new emitter, composed of azatriangulene and diphenyltriazine moieties, is theoretically designed, which is coplanar due to intramolecular H‐bonding interactions. The synthesis of this hexamethylazatriangulene‐triazine (HMAT‐TRZ) emitter and its preliminary photophysical characterizations point to HMAT‐TRZ as a potential efficient TADF emitter.

Published: October 2017

AbstractRational surface engineering of 2D nanoarchitectures‐based electrode materials is crucial as it may enable fast ion transport, abundant‐surface‐controlled energy storage, long‐term structural integrity, and high‐rate cycling performance. Here we developed the stacked ultrathin Co3O4 nanosheets with surface functionalization (SUCNs‐SF) converted from layered hydroxides with inheritance of included anion groups (OH−, NO3−, CO32−). Such stacked structure establishes 2D nanofluidic channels offering extra lithium storage sites, accelerated Li‐ion transport, and sufficient buffering space for volume change during electrochemical processes. Tested as an anode material, this unique nanoarchitecture delivers high specific capacity (1230 and 1011 mAh g−1 at 0.2 and 1 A g−1, respectively), excellent rate performance, and long cycle capability (1500 cycles at 5 A g−1). The demonstrated advantageous features by constructing 2D nanochannels in nonlayered materials may open up possibilities for designing high‐power lithium ion batteries.

Published: October 2017

AbstractN‐bromosuccinimide (NBS)‐mediated one‐pot, green, efficient and practical synthesis of substituted imidazoles and quinoxalines has been achieved by the reaction of styrenes with N‐arylbenzamidines and o‐phenylenediamines, respectively, in a water:1,4‐dioxane mixture. The reaction involves formation of an α‐bromo ketone as an intermediate in the presence of NBS and water, followed by condensation with the N‐arylbenzamidine and o‐phenylenediamine. Use of an inexpensive NBS as a bromine source as well as an oxidant, water as a solvent and readily available starting materials makes this protocol environmentally benign and economically viable. Substituted imidazoles and quinoxalines were obtained in good to excellent yields with wide functional group compatibility.magnified image
Nitrogen‐Doped Porous Molybdenum Carbide and Phosphide Hybrids on a Carbon Matrix as Highly Effective Electrocatalysts for the Hydrogen Evolution Reaction
Authors: Huang Yichao , Ge Jingxuan , Hu Jun , Zhang Jiangwei , Hao Jian , Wei Yongge 
Published: October 2017

AbstractThe efficient evolution of hydrogen through electrocatalysis is considered a promising approach to the production of clean hydrogen fuel. Platinum (Pt)‐based materials are regarded as the most active hydrogen evolution reaction (HER) catalysts. However, the low abundance and high cost of Pt hinders the large‐scale application of these catalysts. Active, inexpensive, and earth‐abundant electrocatalysts to replace Pt‐based materials would be highly beneficial to the production of cost‐effective hydrogen energy. Herein, a novel organoimido‐derivatized heteropolyoxometalate, Mo4‐CNP, is designed as a precursor for electrocatalysts of the HER. It is demonstrated that the carbon, nitrogen, and phosphorus sources derived from the Mo4‐CNP molecules lead to in situ confined carburization, phosphorization, and chemical doping on an atomic scale, thus forming nitrogen‐doped porous molybdenum carbide and phosphide hybrids, which exhibit remarkable electrocatalytic activity for the HER. Such an organically functionalized polyoxometalate‐assisted strategy described here provides a new perspective for the development of highly active non‐noble metal electrocatalysts for hydrogen evolution.

Published: October 2017

AbstractLokalisierte molekulare Selbstorganisationsprozesse, die zum Wachstum von Nanostrukturen ausschließlich an der Oberfläche eines Materials führen, sind eine der großen Herausforderungen in der Oberflächenchemie. In den letzten zehn Jahren wurde in mehreren Studien berichtet, wie modifizierte oder unmodifizierte Oberflächen die Selbstorganisation von niedermolekularen Hydrogelatoren (LMWHs) vermitteln und lokalisierte supramolekulare Hydrogelschichten, hauptsächlich in Form von Nanofaserarchitekturen, bilden. Dieser Kurzaufsatz diskutiert neuere Strategien für die lokalisierte, durch LMWHs vermittelte Bildung von supramolekularen Hydrogelen sowie deren Eigenschaften und Anwendungen.

AbstractA one‐step synthesis of nanotubes by RAFT dispersion polymerization of cyclodextrin/styrene (CD/St) complexes directly in water is presented. The resulted amphiphilic PEG‐b‐PS diblock copolymers self‐assemble in situ into nanoparticles with various morphologies. Spheres, worms, lamellae, and nanotubes were controllably obtained. Because of the complexation, the swelling degree of polystyrene (PS) blocks by free St is limited, resulting in limited mobility of PS chains. Consequently, kinetically trapped lamellae and nanotubes were obtained instead of spherical vesicles. During the formation of nanotubes, small vesicles first formed at the ends of the tape‐like lamellae, then grew and fused into nanotubes with a limited chain rearrangement. The introduction of a host–guest interaction based on CDs enables the aqueous dispersion polymerization of water‐immiscible monomers, and produces kinetically trapped nanostructures, which could be a powerful technique for nanomaterials synthesis.

Published: October 2017

AbstractN‐Boc ketimines derived from pyrazolin‐5‐ones were explored to develop an unprecedented domino aza‐Friedel–Crafts/N,O‐acetalization reaction with 2‐naphthols. The novel method requires a catalyst loading of only 0.5 mol % of a bifunctional squaramide catalyst, is scalable to gram amounts, and provides a new series of furanonaphthopyrazolidinone derivatives bearing two vicinal tetra‐substituted stereogenic centers in excellent yields (95–98 %) and stereoselectivity (>99:1 d.r. and 97–98 % ee). A different reactivity was observed in the case of 1‐naphthols and other electron‐rich phenols, which led to the aza‐Friedel–Crafts adducts in 70–98 % yield and 47–98 % ee.

Published: October 2017

AbstractUbiquitylation, the modification of proteins with ubiquitin (Ub), is one of the most versatile post‐translational modifications in eukaryotic cells. Since Ub also serves as its own substrate, proteins can be modified by numerous different Ub chains, in which the individual moieties are linked via one or several of the seven lysines of Ub. Homogeneous Ub chains, in which the moieties are sequentially linked via the same residue, have been most extensively studied. However, due to their restricted availability, the functions of Ub chains linked via K27, K29, or K33 are poorly understood. We have developed an approach that, for the first time, allows the generation of all seven homogeneous Ub chains in large quantities. The potential of our approach is demonstrated by the identification of previously unknown interaction partners of K27‐, K29‐, and K33‐linked Ub chains by affinity‐based proteomics.
Aqueous Gold Overgrowth of Silver Nanoparticles: Merging the Plasmonic Properties of Silver with the Functionality of Gold

Published: October 2017

AbstractTo date, it has not been possible to combine the high optical quality of silver particles with the good chemical stability and synthetic convenience in a fully aqueous system, while simultaneously allowing chemical surface functionalization. We present a synthetic pathway for future developments in information, energy and medical technology where strong optical/electronic properties are crucial. Therefore, the advantages inherent to gold are fused with the plasmonic properties of silver in a fully aqueous Au/Ag/Au core–shell shell system. These nanoparticles inherit low dispersity from their masked gold cores, yet simultaneously exhibit the strong plasmonic properties of silver. Protecting the silver surface with a thin gold layer enables oxidant stability and functionality without altering the Ag‐controlled optical properties. This combines both worlds—optical quality and chemical stability—and is not limited to a specific particle shape.

Published: October 2017

AbstractLocalized molecular self‐assembly processes leading to the growth of nanostructures exclusively from the surface of a material is one of the great challenges in surface chemistry. In the last decade, several works have been reported on the ability of modified or unmodified surfaces to manage the self‐assembly of low‐molecular‐weight hydrogelators (LMWH) resulting in localized supramolecular hydrogel coatings mainly based on nanofiber architectures. This Minireview highlights all strategies that have emerged recently to initiate and localize LMWH supramolecular hydrogel formation, their related fundamental issues and applications.
