Effect of the composition and degree of crosslinking on the properties of poly(l‐lactic acid)/crosslinked polyurethane blends
Authors: Ma Meng , Liu Kai , Zheng Haiming , Chen Si , Wu Bozhen , Shi Yanqin , Wang Xu 
Published: May 2018

AbstractPoly(l‐lactic acid)/crosslinked polyurethane (PLLA/CPU) blends which were prepared via reactive blending of PLLA with poly(ϵ‐caprolactone) (PCL), glycerol and 4,4′‐methylenediphenyl diisocyanate showed excellent toughness. The effects of the composition of the mixture and degree of crosslinking of CPU on the toughness of the PLLA/CPU blends (80/20 w/w) were studied in detail. Dynamic mechanical analysis and rheological measurements were used to characterize the structure of the in situ formed CPU in the PLLA matrix. A novel netlike phase structure was observed when the average molecular weight of PCL and degree of crosslinking were 1 kDa and 10%, respectively. The impact strength of the blend was enhanced from 2.2 kJ m−2 for pure PLLA to 62.4 kJ m−2; meanwhile, the elongation at break was increased to 489.8%. Therefore, the mechanical properties of PLLA/CPU blends can be easily tailored by tuning the composition of the mixture and the degree of crosslinking of CPU. © 2018 Society of Chemical Industry

AbstractBACKGROUNDThe Spodoptera cosmioides (Walker, 1858) population has increased in Bacillus thuringiensis Berliner (Bt) soybean crops in Argentina. As there are no registered products for its control, the recommended insecticides for S. frugiperda are used. The aim of this study was therefore to determine the lethal concentration (LC) of chlorantraniliprole and its sublethal effects on the biological and reproductive functions of S. cosmioides, an emerging soybean pest in Argentina.RESULTSAn ingestion toxicity bioassay showed that chlorantraniliprole was active against larvae of the second instar, and after 48 h of exposure LC50 was 0.054 µg mL−1 H2O. In the study of sublethal effect, chlorantraniliprole induced changes in the life cycle of exposed S. cosmioides, which required more time to complete all stages of development (larval, pupal and adult stages). Pupal weight was also higher in larvae exposed to sublethal concentrations of chlorantraniliprole. Adult fecundity was decreased: the number of eggs laid by each adult female moth, as compared with control females, was two (LC15) and eight (LC30) times lower.CONCLUSIONThese results indicate that chlorantraniliprole has toxicity against S. cosmioides larvae. Sublethal effects on the biological and reproductive performance of this species can help optimize integrated pest management programs. © 2018 Society of Chemical Industry
Contribution of wind energy to balancing markets: The case of Spain

Published: May 2018

Ancillary services are intended to ensure the quality, reliability, and security conditions of the electricity supply. Active power‐related ancillary services are considered balancing services, including mandatory services, such as spinning or primary regulation, and optional services, such as secondary and tertiary regulation. These optional balancing services have typically been supplied by conventional power plants, but since their contribution to the production share is decreasing due to high renewable energy penetration, power system operators are currently in need of alternatives. In addition, the recent advances in both the wind power industry and power system observability and controllability, and the necessary changes in balancing markets have made it technically and economically possible for wind power plants to contribute to optional balancing services. Under this framework, our study focuses on the contribution of wind power to balancing markets in the Spanish power system. Specifically, this work analyses the operational capability test for wind energy active power ancillary services provision and the results of the participation of wind energy to tertiary regulation and imbalance management from February 2016 to July 2017. Furthermore, the analysis includes a comparison with other generation technologies and the identification of upward and downward direction margins. These results show the real experience of the contribution of Spanish wind energy to optional active power ancillary services.This article is categorized under:

Challenges and Strategies for Undertaking Continuous Experimentation to Embedded Systems: Industry and Research Perspectives
Authors: Mattos David Issa , Bosch Jan , Olsson Helena Holmström 
Published: May 2018

AbstractContext: Continuous experimentation is frequently used in web-facing companies and it is starting to gain the attention of embedded systems companies. However, embedded systems companies have different challenges and requirements to run experiments in their systems. Objective: This paper explores the challenges during the adoption of continuous experimentation in embedded systems from both industry practice and academic research. It presents strategies, guidelines, and solutions to overcome each of the identified challenges. Method: This research was conducted in two parts. The first part is a literature review with the aim to analyze the challenges in adopting continuous experimentation from the research perspective. The second part is a multiple case study based on interviews and workshop sessions with five companies to understand the challenges from the industry perspective and how they are working to overcome them. Results: This study found a set of twelve challenges divided into three areas; technical, business, and organizational challenges and strategies grouped into three categories, architecture, data handling and development processes. Conclusions: The set of identified challenges are presented with a set of strategies, guidelines, and solutions. To the knowledge of the authors, this paper is the first to provide an extensive list of challenges and strategies for continuous experimentation in embedded systems. Moreover, this research points out open challenges and the need for new tools and novel solutions for the further development of experimentation in embedded systems.
Enterprise Agility: Why Is Transformation so Hard?
Authors: Karvonen Teemu , Sharp Helen , Barroca Leonor 
Published: May 2018

Abstract
Enterprise agility requires capabilities to transform, sense and seize new business opportunities more quickly than competitors. However, acquiring those capabilities, such as continuous delivery and scaling agility to product programmes, portfolios and business models, is challenging in many organisations. This paper introduces definitions of enterprise agility involving business management and cultural lenses for analysing large-scale agile transformation. The case organisation, in the higher education domain, leverages collaborative discovery sprints and an experimental programme to enable a bottom-up approach to transformation. Meanwhile the prevalence of bureaucracy and organisational silos are often contradictory to agile principles and values. The case study results identify transformation challenges based on observations from a five-month research period. Initial findings indicate that increased focus on organisational culture and leveraging of both bottom-up innovation and supportive top-down leadership activities, could enhance the likelihood of a successful transformation.
Explaining the “ebb and flow” of the problem stream: frame conflicts over the future of coal seam gas (“fracking”) in Australia
Authors: Fawcett Paul , Jensen Michael J. , Ransan-Cooper Hedda , Duus Sonya 
Published: May 2018

AbstractWhy do issues “fade” from the problem stream? This is an important but underresearched question, which this article examines by looking at the dynamic interaction between frames and frame sponsors. We develop a novel methodological approach that combines algorithmic coding (topic modelling) with hand-coding to track changes in the presence of frames and frame sponsors during periods of intense problematisation (“problem windows”) both within continuous contexts and diachronically across different contexts. We apply this approach empirically in a corpus of newspaper articles that pertain to the coal seam gas controversy in Australia – a divisive policy issue where frame conflicts are common. We find that elite actors have a particularly decisive impact on the problem stream in terms of both the evolution and duration of debate. Further, problem windows close in response to three different mechanisms: elite frame convergence; public statements (by government and industry); and elections.
Syllables and inflectional morphemes in early Finnish readers: evidence from eye-movements
Authors: HÄIKIÖ Tuomo , VAINIO Seppo 
Published: May 2018

AbstractFinnish is a language with simple syllable structure but rich morphology. It was investigated whether syllables or morphemes are preferred processing units in early reading. To this end, Finnish first- and second-grade children read sentences with embedded inflected target words while their eye-movements were registered. The target words were either in essive or inessive/adessive (i.e., locative) case. The target words were either non-hyphenated, or had syllable-congruent or syllable-incongruent hyphenation. For the locatives, the syllable-incongruent hyphenation coincided with the morpheme boundary, but this was not the case for the essives. It was shown that the second-graders were slowed down by hyphenation to a larger extent than first-graders. However, there was no slowdown in gaze duration for either age group when the syllable-incongruent hyphen was morpheme-congruent. These findings suggest that Finnish readers already utilize morpheme-level information during the first grade.
Variation of Tamagawa numbers of semistable abelian varieties in field extensions
Authors: BETTS L. ALEXANDER , DOKCHITSER VLADIMIR , DOKCHITSER V. , MORGAN A. 
Published: May 2018

AbstractWe investigate the behaviour of Tamagawa numbers of semistable principally polarised abelian varieties in extensions of local fields. In particular, we give a simple formula for the change of Tamagawa numbers in totally ramified extensions and one that computes Tamagawa numbers up to rational squares in general extensions. As an application, we extend some of the existing results on thep-parity conjecture for Selmer groups of abelian varieties by allowing more general local behaviour. We also give a complete classification of the behaviour of Tamagawa numbers for semistable 2-dimensional principally polarised abelian varieties that is similar to the well-known one for elliptic curves. The appendix explains how to use this classification for Jacobians of genus 2 hyperelliptic curves given by equations of the formy2=f(x), under some simplifying hypotheses.
The European Historic Towns Atlas project: success and challenges (with particular reference to the Irish Historic Towns Atlas)
Authors: SIMMS ANNGRET , GEARTY SARAH 
Published: May 2018

ABSTRACT:The European Historic Towns Atlas project, probably the largest one in European urban history, is conceptually rooted in national histories. Methodologically it is focused on the production and interpretation of large-scale maps primarily for the understanding of urban morphogenesis and the role of morphological agents but also of issues connected with the economic and cultural aspects of urban life. The atlas project now involves 19 countries and with over 520 towns produced across Europe, pioneer comparative urban studies have been published. Comparative work based on theoretical underpinning is the aim of the project and though it holds great potential, it also faces challenges: access to published towns, language barriers and consistency between national productions. It is argued that the digital production of the atlases may provide a chance for a more unified approach in the future.
“MISS X,” TELEPATHY, AND AFFECT ATFIN DE SIÈCLE
Authors: Zieger Susan 
Published: May 2018

In his bookApparitions and Thought-Transference:An Examination of the Evidence for Telepathy(1895), Frank Podmore relates what might at first seem a humdrum occurrence of settling into bedtime reading. The diary he has transcribed, of a woman he calls D, records on January 6th, “Tried several books . . . finally took to ‘Villette.’” But D’s choice was not completely autonomous. She was clearly influenced by her friend, “X.” As Podmore wrote, “From Miss X's diary it appears that she willed D to readThe Professor,” which he notes, portentously, was “also by Charlotte Brontë.” X got luckier – or honed her skills – a few weeks later, when D recorded “Sonnets by E.B.B. 10:30 p.m.” and “In Miss X's diary, written at about 10 p.m., appears the entry, ‘Sonnets viii-ix., E.B.B.’” Assessing the records, Podmore found X's influence over D's literary taste to be “presumably telepathic” (122–23). Although the phenomenon was sensational, the circumstances surrounding it were decidedly mundane, ranging from bedtime reading to hearing X's piano-playing at a distance of miles, and meeting specific people at certain times. At a second glance, the phenomenon remains humdrum. Gauri Viswanathan has described how the institutionalization of Theosophy created reality effects that routinized its mysticism, rendering it ordinary (7). Similarly, though psychical research studied the numinous, its institutions ensconced it in bureaucracy, making it mundane. In the last quarter of the nineteenth century in Britain, the oddly interesting-yet-boring phenomenon of thought-reading became a cultural activity that ranged between scientific research, domestic pastime, and popular entertainment. Could people read each other's minds? If so, how was it done? Thought-reading arose to compete with Spiritualism, the practice of contacting the dead through séances. Its most mysterious public persona, and one of the more intriguing historical figures of the period, was Podmore's aficionado of Charlotte Brontë and Elizabeth Barrett Browning, the presumed telepath known as Miss X.
Poverty and climate change: introduction
Authors: Hallegatte Stephane , Fay Marianne , Barbier Edward B. 
Published: May 2018

AbstractBecause their assets and income represent such a small share of national wealth, the impacts of climate change on poor people, even if dramatic, will be largely invisible in aggregate economic statistics such as the Gross Domestic Product (GDP). Assessing and managing future impacts of climate change on poverty requires different metrics, and specific studies focusing on the vulnerability of poor people. This special issue provides a set of such studies, looking at the exposure and vulnerability of people living in poverty to shocks and stressors that are expected to increase in frequency or intensity due to climate change, such as floods, droughts, heat waves, and impacts on agricultural production and ecosystem services. This introduction summarizes their approach and findings, which support the idea that the link between poverty and climate vulnerability goes both ways: poverty is one major driver of people's vulnerability to climate-related shocks and stressors, and this vulnerability is keeping people in poverty. The paper concludes by identifying priorities for future research.
Diet quality and depressive symptoms in adolescence: no cross-sectional or prospective associations following adjustment for covariates

Published: May 2018

AbstractObjectiveAdolescence is a critical period for development of depression and understanding of behavioural risk factors is needed to support appropriate preventive strategies. We examined associations between adolescent diet quality and depressive symptoms, cross-sectionally and prospectively, in a large community cohort, adjusting for behavioural and psychosocial covariates.DesignProspective community-based cohort study (ROOTS).SettingSecondary schools in Cambridgeshire and Suffolk, UK.SubjectsStudy participants (n 603) who completed 4 d diet diaries at age 14 years and reported depressive symptoms (Moods and Feelings Questionnaire (MFQ)) at 14 and 17 years of age.ResultsDiet data were processed to derive a Mediterranean diet score (MDS) and daily servings of fruit and vegetables, and fish. At age 14 years, a negative association between fruit and vegetable intake and MFQ score was seen in the unadjusted cross-sectional regression model (β=−0·40; 95 % CI −0·71,−0·10), but adjustment for behavioural covariates, including smoking and alcohol consumption, attenuated this association. Fish intake and MDS were not cross-sectionally associated with MFQ score. No prospective associations were found between MDS, fruit and vegetable intake or fish intake and later MFQ score.ConclusionsDiet quality was not associated with depressive symptoms in mid-adolescence. Previously reported associations in this age range may be due to confounding. Further longitudinal studies are needed that investigate associations between adolescent diet and depression across different time frames and populations, ensuring appropriate adjustment for covariates.
Subjectivity and Sociality in Kant’s Theory of Beauty
Authors: Kalar Brent 
Published: May 2018

AbstractKant holds that it is possible to quarrel about judgements of beauty and cultivate taste, but these possibilities have not been adequately accounted for in the dominant interpretations of his aesthetics. They can be better explained if we combine a more subjectivist interpretation of the free harmony of the faculties and aesthetic form with a type of social constructivism. On this ‘subjectivist-constructivist’ reading, quarrelling over and cultivating taste are not attempts to conform to some matter of fact, but rather to reconcile subjective perceptions through mutual interchange governed by the regulative goal of constructing a universal community of agreement.
Kant’s Standpoint Distinction
Authors: Kohl Markus 
Published: May 2018

AbstractI examine what Kant means when he appeals to different standpoints. I argue that Kant seeks to contrast an empirical, anthropocentric standpoint with a normative, more than human standpoint. Against common interpretations, I argue that the normative standpoint is not confined to practical reason, since theoretical reason is concerned with what ought to be as well. Finally, I defend the coherence of Kant’s distinction against important objections.
Ched Evans, rape myths and Medusa's gaze: a story of mirrors and windows
Authors: Gurnham David 
Published: May 2018

AbstractThis paper analyses the visualisation of rape and sexual assault in legal and scholarly language. It begins with a critique of the Court of Appeal ruling inR v. Evans (Chedwyn)and its forensic examination of the details of a female rape complainant's consensual sexual activity with other men. The case is analysed in light of a visual metaphor used by Ellison and Munro to describe the removal of popular misconceptions about rape. The paper contextualises that discussion with reference to the idea of the male gaze and its affirmation of a phallocentric cultural and social world in which the objectification of female difference is entrenched. The paper finally challenges that assessment, however, sketching an alternative approach to visual-critical scholarship that embraces interdisciplinarity and a literary sensibility to break (or at least to loosen) the association between the prurient eye of the male voyeur and the criminal justice gaze.
Localized and Intense Energy Conversion in the Diffusion Region of Asymmetric Magnetic Reconnection
Authors: Swisdak M. , Drake J. F. , Price L. , Burch J. L. , Cassak P. A. , Phan T.‐D. 
Published: May 2018

AbstractWe analyze a high‐resolution simulation of magnetopause reconnection observed by the Magnetospheric Multiscale mission and explain the occurrence of strongly localized dissipation with an amplitude more than an order of magnitude larger than expected. Unlike symmetric reconnection, wherein reconnection of the ambient reversed magnetic field drives the dissipation, we find that the annihilation of the self‐generated, out‐of‐plane (Hall) magnetic field plays the dominant role. Electrons flow along the magnetosheath separatrices, converge in the diffusion region, and jet past the X‐point into the magnetosphere. The resulting accumulation of negative charge generates intense parallel electric fields that eject electrons along the magnetospheric separatrices and produce field‐aligned beams. Many of these features match Magnetospheric Multiscale observations.
Gauging the Improvement of Recent Mean Sea Surface Models: A New Approach for Identifying and Quantifying Their Errors

Published: May 2018

AbstractThis paper presents an assessment and comparison of recent mean sea surface (MSS) models. Using a new approach and independent altimeter data sets, we quantify the major improvement of the CNES_CLS15 and the DTU15 models. We observe a reduction in the amplitude of omission errors thanks to the use of new geodetic altimeter data sets (i.e., Cryosat‐2 and Jason‐1 geodetic): they are reduced by a factor of 2 compared with previous generations (CNES_CLS11). We also quantify commission errors resulting from the leakage of residual ocean variability and altimeter noise into the MSS models. For wavelengths shorter than 250 km, the error is of the order of 1–2 cm2, i.e., ∼10% to 20% of the sea level anomaly (SLA) variance. The global error of both 2015 models has similar orders of magnitude and spectral power densities, although the commission errors of the CNES_CLS15 model are about half as large as those of the DTU15 model. Its absolute error is also slightly smaller than for the DTU15 model in coastal regions and at high latitudes. Conversely, the DTU15 model produces smaller omission errors, especially in the open ocean over strong bathymetric features. More importantly, the MSS errors still have a substantial impact on altimetry products for wavelengths ranging from 30 to 100 km: the error explains ∼30% of the global SLA variance, and the error can be 2.5 times higher on uncharted ground tracks (e.g., Sentinel‐3) over rugged bathymetry.
