The Predictors of Unmet Demand for Unions in Non-Union Workplaces: Lessons from Australia
Authors: Pyman Amanda , Teicher Julian , Cooper Brian , Holland Peter 
Published: August 2017

In this study, we examine the predictors of unmet demand for unions in non-union workplaces, using theAustralian Worker Representation and Participation Survey(AWRPS). Unmet demand is defined here, as those employees in non-union workplaces who would be likely to join a union if one were available. We argue that this is the first study in Australia to examine the predictors of unmet demand in non-union workplaces, and, that this is an important line of inquiry given a rise in non-union workplaces and never members in Australia, alongside declining union density and membership numbers. Drawing on three strands of existing literature, namely the individual propensity to unionize, the rise and characteristics of non-union workplaces and alternative forms of representation, and, managerial responsiveness to employees and unions, we develop and test four hypotheses.Our results show, controlling for a range of personal, job and workplace characteristics, that there are two significant predictors of the willingness to join a union in non-union workplaces: perceived union instrumentality (Hypothesis 2) and perceived managerial responsiveness to employees (Hypothesis 4), whereby employees who perceive that managers lack responsiveness are more likely to want to join a union if one were available.These results show that unions must try to enhance their instrumentality in workplaces and could be more effective in recruiting if they targeted never members. The results also show that unions need to have some gauge (measure) of how responsive managers are to employees, and that they can leverage poor responsiveness of managers for membership gain and the extension of organizing. In the final analysis, an understanding of the predictors of unmet demand for unions in non-union workplaces has implications for Australian unions’ servicing and organizing strategies, and for their future growth prospects.
Assurer son employabilité militante externe par la mobilisation du capital social : le cas des ex-permanents syndicaux lors d’une reconversion en dehors du syndicat
Authors: de Becdelièvre Pauline , Grima François 
Published: August 2017

À partir d’une recherche qualitative auprès de 48 ex-militants syndicaux ayant eu plus de 80% de leur temps de travail pour leur syndicat, de 10 directeurs des Ressources humaines et de trois organisations syndicales, une organisation patronale et un cabinet d’accompagnement, cet article questionne la reconversion des militants syndicaux en dehors de la sphère syndicale. En s’appuyant sur le contexte français et la littérature existante sur la reconversion des militants syndicaux, nos travaux soulignent les stratégies mises en place par les ex-militants afin d’assurer leur employabilité militante externe.
Ces stratégies sont influencées par la perception qu’ils ont de leur employabilité. Plusieurs facteurs externes et individuels affectent cette perception. Les facteurs individuels sont le capital social perçu, la nature du départ (subi ou volontaire), le niveau de poste précèdent et le niveau atteint dans l’organisation syndicale. Ces facteurs individuels n’expliquent pas tout. D’autres facteurs externes, tels la stigmatisation dont peut faire l’objet le militant à cause de son engagement syndical, le lien contractuel et l’accompagnement du syndicat, expliquent la perception que le militant a de son employabilité. Celle-ci entraine soit une non mobilisation du capital social, soit une mobilisation offensive du capital social. Dans ce dernier cas, l’ex-permanent peut subir une phase d’observation de la part de l’entreprise d’accueil.
En s’intéressant à la reconversion syndicale, cette recherche constitue un renversement de positionnement par rapport aux nombreux travaux analysant la carrière syndicale. Le capital social des militants n’est plus pensé au sein de l’organisation syndicale, mais en dehors de celle-ci, et il permet de proposer le concept d’employabilité militante externe, à savoir la capacité d’un ex-militant syndical d’obtenir un travail et de se maintenir en emploi en dehors du syndicat grâce à la mobilisation de son capital social.
Les conflits sociaux et identitaires à travers la Nouvelle Chanson Chilienne : une approche culturelle de l’histoire politique du Chili, 1950-1973
Authors: Prom Aurélie 
Published: August 2017

Au début du XXe siècle, le Chili et plus largement l’Amérique latine connaissent une situation générale de luttes ouvrières, de mouvements syndicalistes revendiquant des droits et une place dans la société bien longtemps niés par le pouvoir en place, conduisant à des affrontements violents dont les conséquences vont dépasser le périmètre de l’entreprise concernée. Au Chili, le mouvement ouvrier dans les années 1950 devient alors une véritable force politique et la situation politique chilienne permet d’illustrer ces conflits. À cette même époque nait dans cette agitation socio-politique un mouvement musical et culturel, la Nouvelle Chanson Chilienne, qui, s’il se revendique chilien, s’inscrit également dans une logique socioculturelle latino-américaine et plus particulièrement dans les conflits sociaux, en faveur des secteurs populaires. Aussi, c’est à travers une sélection de textes de chansons, la « Cantata de Santa Maria de Iquique » ainsi que certaines chansons de Violeta Parra et de Victor Jara que nous chercherons ici à illustrer une situation de conflit, en réponse à cette violence faite au peuple, qu’il s’agisse d’une grève ou du délogement des secteurs pauvres des « poblaciones ». Comment la nouvelle chanson illustre-t-elle les conflits sociaux propres au Chili et plus largement à l’Amérique latine au début du XXe siècle, à la fois acte de mémoire et de revendication politique et identitaire ?

AbstractPlanets and satellites can undergo physical librations, which consist of forced periodic variations in their rotation rate induced by gravitational interactions with nearby bodies. This mechanical forcing may drive turbulence in interior fluid layers such as subsurface oceans and metallic liquid cores through a libration‐driven elliptical instability (LDEI) that refers to the resonance of two inertial modes with the libration‐induced base flow. LDEI has been studied in the case of a full ellipsoid. Here we address for the first time the question of the persistence of LDEI in the more geophysically relevant ellipsoidal shell geometries. In the experimental setup, an ellipsoidal container with spherical inner cores of different sizes is filled with water. Direct side view flow visualizations are made in the librating frame using Kalliroscope particles. A Fourier analysis of the light intensity fluctuations extracted from recorded movies shows that the presence of an inner core leads to spatial heterogeneities but does not prevent LDEI. Particle image velocimetry and direct numerical simulations are performed on selected cases to confirm our results. Additionally, our survey at a fixed forcing frequency and variable rotation period (i.e., variable Ekman number, E) shows that the libration amplitude at the instability threshold varies as ∼E0.65. This scaling is explained by a competition between surface and bulk dissipation. When extrapolating to planetary interior conditions, this leads to the E1/2 scaling commonly considered. We argue that Enceladus' subsurface ocean and the core of the exoplanet 55 CnC e should both be unstable to LDEI.

AbstractMethods for microfabrication of solderable and stretchable sensing systems (S4s) and a scaled production of adhesive‐integrated active S4s for health monitoring are presented. S4s' excellent solderability is achieved by the sputter‐deposited nickel‐vanadium and gold pad metal layers and copper interconnection. The donor substrate, which is modified with “PI islands” to become selectively adhesive for the S4s, allows the heterogeneous devices to be integrated with large‐area adhesives for packaging. The feasibility for S4‐based health monitoring is demonstrated by developing an S4 integrated with a strain gauge and an onboard optical indication circuit. Owing to S4s' compatibility with the standard printed circuit board assembly processes, a variety of commercially available surface mount chip components, such as the wafer level chip scale packages, chip resistors, and light‐emitting diodes, can be reflow‐soldered onto S4s without modifications, demonstrating the versatile and modular nature of S4s. Tegaderm‐integrated S4 respiration sensors are tested for robustness for cyclic deformation, maximum stretchability, durability, and biocompatibility for multiday wear time. The results of the tests and demonstration of the respiration sensing indicate that the adhesive‐integrated S4s can provide end users a way for unobtrusive health monitoring.

AbstractMn doped caesium lead halide perovskite (CsPbCl3‐Mn) nanocrystals are obtained from CsPbBr3 nanocrystals via ion exchange with MnCl2. The doping of Mn and the activity in energy acceptance in different stages of ion exchange are proved using photoluminescence (PL) lifetime measurement and inductively coupled plasma mass spectrometry measurements. During the ion exchange, ultrasonic treatment and cold flow (in a KCl matrix) are used to assist Mn incorporation. The resulting CsPbCl3‐Mn@KCl shows excellent PL properties and stability. Finally, the CsPbCl3‐Mn@KCl tablet is applied to the production of a light emitting diode prototype.

AbstractA metal‐free construction of highly diastereoselective nine‐membered heterocycles is described via the cycloaddition and rearrangement of N‐vinyl‐α,β‐unsaturated ketonitrones and isocyanates. Notably, the prepared nine‐membered heterocycles afforded 2,3‐dihydropyrrolizines under heating conditions. Mechanistic studies showed that the nine‐membered rings might undergo decarboxylation, isomerization, aza‐Michael addition, and aromatization to afford 2,3‐dihydropyrrolizines in a one‐pot reaction.magnified image

Published: August 2017

AbstractIntroductionA common clinical use of the twinkle artefact is to detect and confirm renal calcification on ultrasound. There is however variable demonstration of this artefact using newer generation ultrasound machines. The purpose of this study was to assess the impact of altering multiple scanning factors on ultrasound machines from four major manufacturers on the demonstration of the twinkle artefact. Two custom‐made phantoms and five‐point Likert‐like Scale were utilised.MethodsThese phantoms contained a range of urinary calculi varying in size, composition, surface contour and depth. The calculi were serially imaged with each ultrasound machine, using manufacturers presets and varying just one imaging factor or parameter at a time. The documented twinkle artefact in the images were subsequently analysed, together with the imaging preset and factor changes that had been made.ResultsThose factors that had the greatest effect in order of impact were colour write priority, colour gain, transducer type, depth of calculus, acoustic power and size of calculus. Variability was also demonstrated between manufacturers.ConclusionBy isolating the effect of scanning factor changes, their importance and contribution to appearances in the ultrasound image can be assessed. Image interpretation in the clinical setting requires an understanding of the underlying physics, particularly in the evaluation of artefacts associated with renal calculi.

Published: August 2017

AbstractHomochirality in peptides is crucial in sustaining “like–like” intermolecular interactions that allow the formation of assemblies and aggregates and is ultimately responsible for the resulting material properties. With the help of a series of stereoisomers of the tripeptide F–F–L, we demonstrate the critical role that peptide stereochemistry plays in the self‐assembly of peptides, guided by molecular recognition, and for self‐sorting. Homochiral self‐assemblies are thermally and mechanically more robust compared to heterochiral self‐assemblies. Morphological studies of the multicomponent peptide systems showed that aggregates formed from homochiral peptides possessed a uniform nano‐fibrous structure, whereas heterochiral systems resulted in self‐sorted systems with a heterogeneous morphology. In essence, homochiral peptides form the stronger aggregates, which may be one of reasons why homochirality is preferred in living systems.

AbstractIt is an ongoing challenge to design and synthesize magnetic materials that undergo colossal thermal expansion and that possess potential applications as microscale or nanoscale actuators with magnetic functionality. A paramagnetic metallocyanate building block was used to construct a cyanide‐bridged Fe‐Co complex featuring both positive and negative colossal volumetric thermal‐expansion behavior. A detailed study revealed that metal‐to‐metal charge transfer between 180 and 240 K induced a volumetric thermal expansion coefficient of 1498 MK−1 accompanied with hysteretic spin transition. Rotation of the magnetic building blocks induced change of π⋅⋅⋅π interactions, resulting in a negative volume expansion coefficient of −489 MK−1, and another hysteretic magnetic transition between 300 and 350 K. This work presents a strategy for incorporating both colossal positive and negative volumetric thermal expansion with shape and magnetic memory effects in a material.
Intramolecular Thioether Crosslinking to Increase the Proteolytic Stability of Affibody Molecules

Published: August 2017

AbstractProtein therapeutics suffer from low oral bioavailability, mainly due to poor membrane permeability and digestion by gastrointestinal proteases. To improve proteolytic stability, intramolecular thioether crosslinks were introduced into a three‐helix affibody molecule binding the human epidermal growth factor receptor (EGFR). Solid‐phase peptide synthesis was used to produce an unmodified control protein domain and three different crosslinked protein domain variants: one with a thioether crosslink between the N‐terminal lysine residue and a cysteine residue in the second loop region (denoted K4), a second with a crosslink between the C‐terminal lysine residue and a cysteine residue in the first loop region (denoted K58), and a third with crosslinks in both positions (denoted K4K58). Circular dichroism (CD) and surface‐plasmon‐resonance‐based (SPR‐based) biosensor studies of the protein domains showed that the three‐helix structure and high‐affinity binding to EGFR were preserved in the crosslinked protein domains. In vitro digestion by gastrointestinal proteases demonstrated that the crosslinked protein domains showed increased stability towards pepsin and towards a combination of trypsin and chymotrypsin.

AbstractObjectiveDetermine the feasibility and predictors of early discharge after minimalist transcatheter aortic valve replacement (TAVR).BackgroundDuration of hospitalization has a direct impact on overall cost of care, but the clinical impact of length of stay (LOS) in patients undergoing minimalist TAVR remains unclear.MethodsWe studied 268 patients who underwent minimalist TAVR. Short LOS (sLOS) was defined as post‐procedural LOS ≤ 3 days and observed in 163 patients. Prolonged LOS (pLOS) was observed in 105 patients. Propensity score matching based on 39 variables yielded 54 pairs of patients in each group. We analyzed 30‐day mortality, 30‐day re‐hospitalization and long‐term survival data. Multivariate regression models were used to define predictors of sLOS.ResultsThirty‐day mortality was 0% versus 5.5% in the sLOS and pLOS groups, respectively (P = 0.08). Incidence of re‐hospitalization was higher in pLOS (13% vs. 3.7%). sLOS was associated with lower odds ratio of minor vascular complication (OR 0.1 [95% CI: 0.01, 0.75], P = 0.05), any bleeding (OR 0.35 [95% CI: 0.14, 0.87], P = 0.02), blood transfusion (OR 0.27 [95% CI: 0.08, 0.81], P = 0.02), and new pacemaker implantation (OR 0.23 [95% CI: 0.1, 0.53], P < 0.001). Discharge to home had a significantly higher odd ratio for sLOS (OR 8.67 [95% CI: 3.59, 23.11], P < 0.001).ConclusionIn appropriately selected patients, sLOS following minimalist TAVR approach in an experienced and high volume center is feasible and safe. Implementing such a strategy may reduce medical costs with the potential clinical benefit of early re‐habilitation for the elderly TAVR population.

AbstractObjectivesTo compare visual estimation with different quantitative coronary angiography (QCA) methods (single‐vessel versus bifurcation software) to assess coronary bifurcation lesions.BackgroundQCA has been developed to overcome the limitations of visual estimation. Conventional QCA however, developed in “straight vessels,” has proved to be inaccurate in bifurcation lesions. Therefore, bifurcation QCA was developed. However, the impact of these different modalities on bifurcation lesion severity classification is yet unknownMethodsFrom a randomized controlled trial investigating a novel bifurcation stent (Clinicaltrials.gov NCT01258972), patients with baseline assessment of lesion severity by means of visual estimation, single‐vessel QCA, 2D bifurcation QCA and 3D bifurcation QCA were included. We included 113 bifurcations lesions in which all 5 modalities were assessed. The primary end‐point was to evaluate how the different modalities affected the classification of bifurcation lesion severity and extent of disease.ResultsOn visual estimation, 100% of lesions had side‐branch diameter stenosis (%DS) >50%, whereas in 83% with single‐vessel QCA, 27% with 2D bifurcation QCA and 26% with 3D bifurcation QCA a side‐branch %DS >50% was found (P < 0.0001). With regard to the percentage of “true” bifurcation lesions, there was a significant difference between visual estimate (100%), single‐vessel QCA (75%) and bifurcation QCA (17% with 2D bifurcation software and 13% with 3D bifurcation software, P < 0.0001).ConclusionsOur study showed that bifurcation lesion complexity was significantly affected when more advanced bifurcation QCA software were used. “True” bifurcation lesion rate was 100% on visual estimation, but as low as 13% when analyzed with dedicated bifurcation QCA software.

AbstractDevelopment of an inexpensive, efficient and robust nanohybrid catalyst as a substitute for platinum in photoelectrocatalytic hydrogen production has been considered intriguing and challenging. In this study, the design and sequential synthesis of a novel cobalt sulfide nanoparticle grafted Porous Organic Polymer nanohybrid (CoSx@POP) is reported and used as an active and durable water‐splitting photoelectrocatalyst in the hydrogen evolution reaction (HER). The specific textural and relevant chemical properties of as‐synthesised nanohybrid materials (Co3O4@POP &CoSx@POP) were investigated by means of XRD, XPS, FTIR, 13C CP MAS NMR, spectroscopy, HR‐TEM, HAADF‐STEM with the corresponding elemental mapping, FE‐SEM and nitrogen physisorption studies. CoSx@POP has been evaluated as a superior photoelectrocatalyst in HER, achieving a current density of 6.43 mA cm−2 at 0 V versus the reversible hydrogen electrode (RHE) in a 0.5 m Na2SO4 electrolyte which outperforms its Co3O4@POP analogue. It was found that the nanohybrid CoSx@POP catalyst exhibited a substantially enhanced catalytic performance of 1.07 μmol min−1cm−2, which is considered to be ca. 10 and 1.94 times higher than that of pristine POP and CoSx, respectively. Remarkable photoelectrocatalytic activity of CoSx@POP compared to Co3O4@POP toward H2 evolution could be attributed to intrinsic synergistic effect of CoSx and POP, leading to the formation of a unique CoSx@POP nanoarchitecture with high porosity, which permits easy diffusion of electrolyte and efficient electron transfer from POP to CoSx during hydrogen generation with a tunable bandgap, that straddles between the reduction and oxidation potential of water.
