Review of the book entitled Cultural-Historical Perspectives on Teacher Education and Development: Learning Teaching, 2010, Routledge: Taylor & Francis Group, London and New York (Edited by Viv Ellis, Anne Edwards, and Peter Smagorinsky). The review first discusses the importance that sociocultural perspective taken on by educationalists has had in the recent paradigms for investigating learning and the significance this has in the development and implementation of Cultural-Historical Activity Theory (CHAT). The review then moves on to discuss how the fourteen chapters of the book go about meeting the main aims of the book:Demonstrate the contribution of sociocultural and cultural-historical activity theory (CHAT) towards an understanding of teacher learning; Offer a strong exemplification of a CHAT research focus in this domain;Show what teachers learn, how they learn and where they learn, using specific research examples based in CHAT.
L’actuació discursiva d’un mestre novell en una classe de llengua catalana: gestió de l’aula i construcció del coneixement
Authors: Casas i  Deseures Mariona 
Published: November 2018

Aquest article presenta un estudi de cas que analitza la interacció a l’aula en l’ensenyament-aprenentatge de llengua catalana a quart de primària. Concretament, l’anàlisi se centra en l'actuació discursiva oral d’un mestre novell des del punt de vista de les estratègies que utilitza per gestionar l'aula i per construir coneixement. A partir de l'instrument d'anàlisi de Castellà et al. 2007, que classifica les estratègies discursives de relació social a l’aula i les estratègies discursives de construcció de coneixement, la recerca es pregunta si l’ensenyant es comporta –durant la sessió enregistrada– com a docent efectiu des del punt de vista discursiu i quines implicacions didàctiques té la seva actuació discursiva. Els resultats demostren que el mestre usa més estratègies de gestió de l’aula que de construcció del coneixement i que el coneixement que construeix és escàs, superficial i repetitiu. Justament, les conclusions intenten respondre fins a quin punt la interacció construeix coneixement i com és el coneixement que es construeix. Partint de la base que la interacció és un mitjà per construir coneixement i no una finalitat per se, el predomini de les estratègies de gestió de l’aula al llarg de la sessió demostra que el mestre usa essencialment la interacció per anar teixint el coneixement, és a dir, que la seva habilitat en la gestió de l’aula facilita l’ensenyament-aprenentatge de coneixements nous. Amb tot, el coneixement que es construeix es caracteritza per la introducció de pocs continguts, per l’absència de reflexió metalingüística i per l’escassa presència de discurs explicatiu. L’article conclou que l’ensenyant es comporta com un mestre novell estratègic, en el sentit que la destresa gestionant l’aula atenua la seva inexpertesa construint coneixement. L’interès d’aquesta recerca rau en l’aportació d’unes reflexions sobre l’actuació discursiva d’un ensenyant novell, que poden contribuir a la millora de la formació i la pràctica docents.

Neoliberal Feminism: An Oxymoron?

Resum: En el present escrit tractem d’aproximar-nos al concepte de “feminisme neoliberal” per tal d’identificar-ne les principals característiques i contradiccions. Així doncs, l’objectiu principal que ens plantegem tracta de discernir si és possible, atenent al context actual de desenvolupament del moviment feminista en un marc neoliberal, parlar de “feminisme neoliberal”, o si pel contrari, es tracta d’un concepte que és en sí mateix un oxímoron. Partint del sentit de transformació social cap a la justícia intrínsec al moviment feminista, tractarem de veure com la lògica neoliberal ha condicionat o influenciat en aquest moviment en l’actualitat. Alhora establirem una hipòtesis que es formula com segueix: l’existència d’una identitat feminista neoliberal conviu amb un ressorgiment de l’arrel política del feminisme, cosa que converteix l’escenari actual en un context ple de reptes i dilemes per a aquest moviment. Concloem que en aquests temps el compromís crític del feminisme s’ha de mostrar més fort que mai front a les immanències del sistema neoliberal.

Paraules clau: feminisme neoliberal, postfeminisme, neoliberalisme, governabilitat.

Abstract: In this paper we approach the concept “Neoliberal Feminism” in order to identify their main characteristics and contradictions. The main objective of this paper is to discern whether it is possible to talk about “Neoliberal Feminism” in response to the development of feminism in a neoliberal framework, or on the contrary, whether this concept is just an oxymoron. Departing from the sense of social transformation towards justice intrinsic to the feminist movement, we address how the neoliberal logic has conditioned or influenced this movement at present. At the same time, we establish a hypothesis that is formulated as follows: the existence of a neoliberal feminist identity coexists with a resurgence of the political roots of feminism. This reality turns the current scenario into a context full of challenges and dilemmas for the feminist struggle. We conclude that nowadays the critical commitment of feminism must be stronger than ever in front of the immanence of the neoliberal system.

Published: November 2018

Background
Postnatal bonding constitutes a major process during the postpartum period, and there is evidence that bonding difficulties have negative consequences for parents’ mental health and the child’s development. However, the conceptualization of postnatal bonding presents inconsistencies, as well as problems in having instruments that encompasses the father figure. The objective was to adapt the maternal postnatal attachment scale (MPAS) and the paternal postnatal attachment scale (PPAS) to Spanish, to evaluate its validity and reliability and to analyze the construct dimensionality of both questionnaires from a gender perspective.

Methods
Instrumental design. In 2016–2017, a sample of 571 mothers and 376 fathers, with children between 6 and 11 months of age, responded to the Spanish version of MPAS and PPAS, respectively. After a process of translation-back-translation of the instrument, we empirically analyzed the internal consistency (Cronbach alpha, composite reliability (CR)) construct and concurrent validity (with regard to postpartum depression and dyadic adjustment). Additionally, we studied the instrument’s content validity, using the Delphi methodology; and the differential analysis in both samples (mothers and fathers), examining the invariance.

Results
A short version of 15 items was obtained, common for mothers and fathers. The results of the Delphi methodology showed a 100% inter-judge agreement, highlighting the absence of differences in the adequacy of the items as a function of the parents’ gender. Confirmatory factor analysis showed a good fit of three original factors proposed by the authors. The global Cronbach alpha coefficients in the total sample were adequate (mothers, 0.70; fathers, 0.78); and Cronbach alpha of each dimension in the case of mothers was 0.50 (Quality of bonding), 0.55 (Absence of hostility), and 0.60 (Pleasure in interaction); in the case of fathers, it was respectively 0.54, 0.64, and 0.72. CR of each dimension were: quality of bonding, 0.74 in mothers and 0.80 in fathers; absence of hostility, 0.93 in mothers and 0.94 in fathers; pleasure in interaction, 0.83 in mothers and 0.90 in fathers. With regard to the analysis of group invariance, the results revealed empirical evidence of configural and metric invariance. Concurrent validity showed moderate negative correlations for postnatal depression (mothers, r = −0.41, p < 0.001; fathers, r = −0.38, p < 0.001), and positive correlations for dyadic adjustment (mothers, r = 0.39, p < 0.001; fathers, r = 0.44, p < 0.001).

Discussion
A new version of the instrument was generated, with good psychometric properties, adequate for use both with mothers and with fathers. This scale helps evaluate postnatal maternal and paternal bonding, allowing to study it from within the family system, a necessary step forward to advance perinatal mental health.
Manipulating Polysulfide Conversion with Strongly Coupled Fe3O4 and Nitrogen Doped Carbon for Stable and High Capacity Lithium–Sulfur Batteries
Authors: Lu Ke , Zhang Hong , Gao Siyuan , Ma Houyi , Chen Junzheng , Cheng Yingwen 
Published: November 2018

AbstractLi–S batteries are among the most promising energy storage technologies but their commercialization faces substantial challenges, largely due to difficulties in controlling their reaction pathways under practical conditions. Here, the synthesis of strongly coupled Fe3O4 and N‐doped carbon directly in flexible carbon cloth is demonstrated, as well as their novel use for hosting sulfur with outstanding performance for Li–S batteries. It is discovered that the synergistic effects of Fe3O4 and N‐carbon bring strong adsorption toward lithium polysulfide, and ensure nearly complete conversion of short‐chain polysulfide to Li2S during discharge. The Li2S solids generated on these novel hosts are extremely reactive and can be readily charged back to S without a noticeable overpotential. The critical roles of Fe3O4 and N‐doped carbon are studied and direct correlations are established between their surface concentration/crystallinity and the Li2S4 to Li2S conversion capacity. This novel manipulation of polysulfide conversion allows to fabricate freestanding and flexible sulfur cathodes that deliver a specific capacity of 1316 mAh g−1 at 0.1C and stable cycling for 1000 cycles at 0.2C under a high sulfur loading of ≈4.7 mg cm−2.
C1‐symmetric β‐Diketiminatoiron(II) Complexes for Hydroamination of Primary Alkenylamines

Published: November 2018

AbstractThe synthesis and solid‐state characterization of an array of well‐defined low‐coordinate C1‐symmetric β‐diketiminatoiron(II) alkyl complexes B3–B6 featuring steric and electronic variations on one of the N‐aryl substituents of the β‐diketiminate ligand scaffold are reported. All complexes display unique catalytic abilities of promoting the selective exo‐cyclohydroamination of unprotected 2,2‐diphenylpent‐4‐en‐1‐amine (1 a) under mild reactions conditions. The incorporation of a potentially coordinative ortho‐methoxy substituent on one of the N‐aryl rings of the β‐diketiminate skeleton, in conjunction with a more crowded 2,6‐diisopropylphenyl group on the other, affords a far more active catalyst (B3) than our previously reported C2‐symmetric β‐diketiminatoiron(II) alkyl complex B (Ar1=Ar2=2,4,6‐(Me)3C6H2)/cyclopentylamine system. Comparative studies let us postulate that this superior activity of B3, when compared with B4‐B6, is likely arising from steric effects and/or the coordinating ability of the ortho‐methoxy substituent. The scope and limitations of this novel C1‐symmetric β‐diketiminatoiron(II) alkyl complex B3 are also presented.magnified image
Chitosan/graphene oxide‐based multifunctional pH‐responsive hydrogel with significant mechanical strength, self‐healing property, and shape memory effect

Published: November 2018

AbstractSynthesis of hydrogel with multifunctional properties still remains a challenge within the scientific community. Hydrogels having stimulus‐responsive properties are a few of the desired properties for real‐life applications. This work highlights the synthesis of multifunctional pH‐sensitive hydrogels, based on chitosan (CS) and graphene oxide (GO), via physical cross‐linking. The properties of hydrogels were optimized using various characterization techniques. Successful GO incorporation into the CS matrix was clearly confirmed by Fourier transform infrared analysis. Scanning electron microscope and TEM micrographs portray rough and porous surface morphology of the composite hydrogels. The prepared hydrogels have demonstrated enhanced thermal properties due to the incorporation of GO. To investigate the pH‐responsive behavior, the pH‐dependent study for the hydrogels was carried out in acidic and basic media. Increasing the amount of GO content inside the gel imparted enhanced mechanical properties to the hydrogel. There was a sharp increase in tensile strength from 4.37 to 20.96 MPa accompanied by an increase in Young's modulus from 0.122 to 0.364 MPa. DMA confirmed better elastic behavior of the composite hydrogel. The hydrogel exhibited fast self‐healing property when cleaved under ambient conditions. In addition, the hydrogel also exhibited a shape memory effect both in the alcoholic solution and in the solution of metal cation.

ObjectiveThe aim of this study was to examine adherence of state guidelines for Colorado workers’ compensation physicians/providers treating individuals as injured workers with chronic pain after initiation of an opioid management program and provider incentives.MethodsA retrospective cohort of chronic, non‐cancer pain claims was constructed from the Colorado's workers’ compensation database. Adherence to treatment guidelines and opioid prescribing practices were evaluated during implementation of a new billing code to incentivize adherence.ResultsOverall, less than 33% of claims showed evidence of opioid management. Comprehensive opioid management was observed in only 4.4% of claims. In 2010, after implementing the new billing code, the ratio of long acting opioids to short acting opioids decreased from 0.2 to 0.13; returning to 0.2 in one year. Similarly, morphine equivalent doses declined for a short period.ConclusionsIncentivizing physicians to adhere to chronic pain management guidelines only temporarily improves prescribing practices.
Optische Chiralitätssensorik mit ligandenfreien, weit verbreiteten Cobaltsalzen

Published: November 2018

AbstractDie Einführung breit anwendbarer chiroptischer Enantiomerenanalytik ist eine anspruchsvolle Aufgabe und erfordert in der Regel sorgfältig entwickelte molekulare Rezeptoren oder supramolekulare Verbindungen. Hier beschreiben wir die enantioselektive Sondierung von 35 Aminosäuren, Phosphonsäuren, Hydroxysäuren, Aminoalkoholen und Diaminen mit ligandenfreien Cobaltsalzen. Die chiroptische Analyse der Enantiomerenzusammensetzung und Konzentration kleinster Probemengen erfolgt mit hoher Genauigkeit mittels weit verbreiteter Cobaltsalze und Wasserstoffperoxid als Oxidationsmittel. Trotz des Fehlens eines zusätzlichen Liganden kann diese auf einfachen Cobaltsalzen basierende Analyse auf aromatische und aliphatische Verbindungen angewendet werden und ergibt intensive CD‐Signale bei hohen Wellenlängen. Diese Methode beseitigt die allgemeine Notwendigkeit von chromophoren Liganden oder der Analyt‐Liganden‐Chiralitätsinduktion, um chiroptische Signale durch Exciton‐gekoppelten Circulardichroismus zu erzeugen, und sie besticht durch operative Einfachheit, Kosteneffizienz, Abfallreduzierung und Geschwindigkeit.
Erforschung der fundamentalen Strukturen des Lebens: Nicht zielgerichtete chemische Analyse von Einzelzellen und subzellulären Strukturen

Published: November 2018

AbstractZellen sind die grundlegende Funktions‐ und Struktureinheit lebender Organismen. Einzellige Gemeinschaften wie auch mehrzellige Spezies produzieren eine erstaunliche chemische Diversität, die eine große Bandbreite an unterschiedlichen Funktionen ermöglicht, dennoch hat jede Zelle zahlreiche Merkmale, die allen lebenden Organismen gemeinsam sind. Während es viele Ansätze zur Erforschung dieser chemischen Diversität gibt, sind nur wenige nicht zielgerichtet und in der Lage, die Analyse von Hunderten von verschiedenen Substanzen mit zellulärer Auflösung zu bewerkstelligen. In diesem Aufsatz diskutieren wir solche nicht zielgerichteten Ansätze, die verwendet werden, um umfassende chemische Analysen durchzuführen, Informationen für die chemische Bildgebung bereitzustellen oder Hochdurchsatz‐Profilingdaten über einzelne Zellen zu erhalten. Die Fähigkeiten der Einzelzellmessung entwickeln sich rasant bezüglich Durchsatz, Nachweisgrenzen und der Vollständigkeit der chemischen Analysen; diese Verbesserungen ermöglichen es, immer komplexere physiologische Phänomene, wie z. B. Lernen, Gedächtnis und Verhalten zu verstehen.
Catalyst‐Sidearm‐Induced Stereoselectivity Switching in Polymerization of a Racemic Lactone for Stereocomplexed Crystalline Polymer with a Circular Life Cycle
Authors: Zhu Jian‐Bo , Chen Eugene Y.‐X. 
Published: November 2018

AbstractConstruction of robust, stereocomplexed (sc) crystalline material, based on a recently discovered infinitely recyclable polymer system, requires blending of enantiomeric polymer chains produced from respective enantiopure, fused six‐five bicyclic lactones. Herein, the stereoselective polymerization of the racemic monomer by yttrium catalysts bearing tetradentate ligands is reported, where the tethered donor sidearm switches the heteroselectivity of the catalyst to isoselectivity when it is changed from the β‐OMe to β‐NMe2 sidearm. The latter catalyst produces an isotactic stereoblock polymer (Pm up to 0.95) that forms the crystalline sc‐material with a Tm of up to 171 °C. This sc‐material can be fully depolymerized back to rac‐monomer in a quantitative yield and purity, thus establishing its circular life cycle.

Published: November 2018

AbstractThe enantioselective N‐heterocyclic carbene catalyzed [3+3] annulation of α‐bromoenals by dynamic kinetic resolution (DKR) of enamines and normal resolution of α,α‐disubstituted imines were developed. The corresponding substituted dihydropyridones were isolated in good yields with excellent diastereo‐ and enantioselectivities, and a high selective factor (up to 83) was realized for the resolution of α,α‐disubstituted imines.
