ABSTRACT
An optical vortex coronagraph has been implemented within the NIRC2 camera on the Keck II telescope and used to carry out on-sky tests and observations. The development of this new L′-band observational mode is described, and an initial demonstration of the new capability is presented: a resolved image of the low-mass companion to HIP 79124, which had previously been detected by means of interferometry. With HIP 79124 B at a projected separation of 186.5 mas, both the small inner working angle of the vortex coronagraph and the related imaging improvements were crucial in imaging this close companion directly. Due to higher Strehl ratios and more relaxed contrasts in L′ band versus H band, this new coronagraphic capability will enable high-contrast, small-angle observations of nearby young exoplanets and disks on a par with those of shorter-wavelength extreme adaptive optics coronagraphs.

ABSTRACT
We present a detailed multiwavelength study of observations from X-ray, near-infrared, and centimeter wavelengths to probe the star formation processes in the S237 region. Multiwavelength images trace an almost sphere-like shell morphology of the region, which is filled with the 0.5–2 keV X-ray emission. The region contains two distinct environments—a bell-shaped cavity-like structure containing the peak of 1.4 GHz emission at center, and elongated filamentary features without any radio detection at edges of the sphere-like shell—where Herschel clumps are detected. Using the 1.4 GHz continuum and 12CO line data, the S237 region is found to be excited by a radio spectral type of B0.5V star and is associated with an expanding H ii region. The photoionized gas appears to be responsible for the origin of the bell-shaped structure. The majority of molecular gas is distributed toward a massive Herschel clump (M
clump ∼ 260

), which contains the filamentary features and has a noticeable velocity gradient. The photometric analysis traces the clusters of young stellar objects (YSOs) mainly toward the bell-shaped structure and the filamentary features. Considering the lower dynamical age of the H ii region (i.e., 0.2–0.8 Myr), these clusters are unlikely to be formed by the expansion of the H ii region. Our results also show the existence of a cluster of YSOs and a massive clump at the intersection of filamentary features, indicating that the collisions of these features may have triggered cluster formation, similar to those found in the Serpens South region.
VARIATIONS BETWEEN DUST AND GAS IN THE DIFFUSE INTERSTELLAR MEDIUM. II. SEARCH FOR COLD GAS
Authors: Reach William T. , Heiles Carl , Bernard Jean-Philippe 
Published: January 2017

ABSTRACT
The content of interstellar clouds, in particular the inventory of diffuse molecular gas, remains uncertain. We identified a sample of isolated clouds, approximately 100 M
⊙ in size, and used the dust content to estimate the total amount of gas. In Paper I, the total inferred gas content was found significantly larger than that seen in 21 cm emission measurements of H i. In this paper we test the hypothesis that the apparent excess “dark” gas is cold H i, which would be evident in absorption but not in emission due to line saturation. The results show that there is not enough 21 cm absorption toward the clouds to explain the total amount of “dark” gas.
RESOLVING THE GEOMETRY OF THE INNERMOST RELATIVISTIC JETS IN ACTIVE GALACTIC NUCLEI

Published: January 2017

ABSTRACT
In the current paradigm, it is believed that the compact VLBI radio core of radio-loud active galactic nuclei (AGNs) represents the innermost upstream regions of relativistic outflows. These regions of AGN jets have generally been modeled by a conical outflow with a roughly constant opening angle and flow speed. Nonetheless, some works suggest that a parabolic geometry would be more appropriate to fit the high energy spectral distribution properties and it has been recently found that, at least in some nearby radio galaxies, the geometry of the innermost regions of the jet is parabolic. We compile here multi-frequency core sizes of archival data to investigate the typically unresolved upstream regions of the jet geometry of a sample of 56 radio-loud AGNs. Data combined from the sources considered here are not consistent with the classic picture of a conical jet starting in the vicinity of the super-massive black hole (SMBH), and may exclude a pure parabolic outflow solution, but rather suggest an intermediate solution with quasi-parabolic streams, which are frequently seen in numerical simulations. Inspection of the large opening angles near the SMBH and the range of the Lorentz factors derived from our results support our analyses. Our result suggests that the conical jet paradigm in AGNs needs to be re-examined by millimeter/sub-millimeter VLBI observations.
Les ERP à l’épreuve de l’organisation
Authors: Besson Patrick 
Published: January 2017

Les difficultés du déploiement des ERP soulèvent une interrogation troublante : avons-nous la maturité et les compétences managériales de cette technologie ? A partir d’une analyse de la conflictualité extraordinaire des projets ERP, l’auteur démontre que la cause principale de l’échec réside dans les limites cognitives des concepteurs d’ERP. Ceux-ci se trompent de concept d’organisation. Ils abordent le projet ERP comme s’il s’agissait d’implanter un dispositif technique sans conséquence organisationnelle significative sur les systèmes de métiers, d’influence et de valeurs des parties prenantes. L’auteur souligne ainsi que la diffusion des nouvelles technologies de l’organisation telles que les ERP suppose une fondation du cadre conceptuel de l’ingénierie organisationnelle autour des trois concepts-clés de processus, de changement et de projet.
Knowledge Adoption in Online Communities of Practice

Published: January 2017

Nous investiguons comment les membres d’une communauté de pratiques (CP) de textes en ligne adopte des connaissances d’autres membres. Les études précédentes portant sur l’adoption des connaissances dans des environnements informatisés se sont appuyées sur les théories du processus dual du traitement de l’information pour comprendre le rôle des indices heuristiques et des probabilités d’élaboration. Ici nous étendons ce courant de recherche en explorant deux nouveaux indices heuristiques : la conformité de genre et la cohérence de l’information. De plus, nous examinons le rôle de la recherche focalisée et de l’information disconfirmatoire pour comprendre comment elles pourraient induire des processus cognitif non heuristiques. Cette étude avance notre compréhension du partage de connaissance dans les CP en ligne. Les résultats suggèrent que le contexte d’une CP en ligne peut jouer un rôle dynamique sur la façon dont les membres traitent la composante contenu de cette CP. En se concentrant sur des technologies de type « pull », elle offre un autre lien théorique entre les communications médiatisées par ordinateur et la gestion des connaissances. Pratiquement, elle apporte aussi des éclairages sur les CP en ligne comme moyen d’améliorer la gestion des connaissances dans les organisations.
‘ROSE concept’ of fluid management: Relevance in neuroanaesthesia and neurocritical care
Authors: Monteiro Joseph , Goraksha Shwetal 
Published: January 2017

AbstractFluid therapy in neurosurgical patients aims to restore intravascular volume, optimise haemodynamic parameters and maintain tissue perfusion, integrity and function. The goal is to minimise the risk of inadequate cerebral perfusion pressure and to maintain good neurosurgical conditions. However, fluid management in brain-injured patients has several distinctive features compared with non-brain-injured critically ill patients. The ROSE concept advocates the restriction of fluids, which is consistent with the prevention of a ‘tight brain’ in neurosurgery. Whether this imbalance in fluid management studies between different types of brain injuries is a reflection of differences in clinical relevance of fluid management is not clear. Further randomised controlled trials in the future are essential in subarachnoid haemorrhage and traumatic brain injury patients who are critical and need long-term Intensive Care Unit stay to elucidate and define the role and relevance of the ROSE concept in neuroanaesthesia and neurocritical care.
Anaesthetic management for combined emergency caesarean section and craniotomy tumour removal
Authors: Bisri Dewi , Wullur Caroline , Bisri Tatang 
Published: January 2017

AbstractPresentation of primary intracranial tumour during pregnancy is extremely rare. Symptoms of brain tumour include nausea, vomiting, headache and seizures which mimic symptoms of pregnancy-related hyperemesis or eclampsia. In very few cases, craniotomy tumour removal is performed earlier or even simultaneously with foetal delivery. A 40-year-old woman at 32 weeks of gestation in foetal distress presented to the emergency room with decreased level of consciousness Glasgow Coma Scale 6 (E2M2V2). Computed tomographic scan revealed a mass lesion over the left temporoparietal region with midline shift and intratumoural bleeding. In view of high risk of herniation and foetal distress, she underwent emergency caesarean section followed by craniotomy tumour removal. In parturient with brain tumour, combined surgery of tumour removal and caesarean section is decided based on clinical symptoms, type of tumour and foetal viability. Successful anaesthetic management requires a comprehensive knowledge of physiology and pharmacology, individually tailored to control intracranial pressure while ensuring the safety of mother and foetus.
Processing and performance of topobathymetric lidar data for geomorphometric and morphological classification in a high-energy tidal environment

Abstract. The transition zone between land and water is difficult to map with conventional geophysical systems due to shallow water depth and often challenging environmental conditions. The emerging technology of airborne topobathymetric light detection and ranging (lidar) is capable of providing both topographic and bathymetric elevation information, using only a single green laser, resulting in a seamless coverage of the land–water transition zone. However, there is no transparent and reproducible method for processing green topobathymetric lidar data into a digital elevation model (DEM). The general processing steps involve data filtering, water surface detection and refraction correction. Specifically, the procedure of water surface detection and modelling, solely using green laser lidar data, has not previously been described in detail for tidal environments. The aim of this study was to fill this gap of knowledge by developing a step-by-step procedure for making a digital water surface model (DWSM) using the green laser lidar data. The detailed description of the processing procedure augments its reliability, makes it user-friendly and repeatable. A DEM was obtained from the processed topobathymetric lidar data collected in spring 2014 from the Knudedyb tidal inlet system in the Danish Wadden Sea. The vertical accuracy of the lidar data is determined to ±8 cm at a 95 % confidence level, and the horizontal accuracy is determined as the mean error to ±10 cm. The lidar technique is found capable of detecting features with a size of less than 1 m2. The derived high-resolution DEM was applied for detection and classification of geomorphometric and morphological features within the natural environment of the study area. Initially, the bathymetric position index (BPI) and the slope of the DEM were used to make a continuous classification of the geomorphometry. Subsequently, stage (or elevation in relation to tidal range) and a combination of statistical neighbourhood analyses (moving average and standard deviation) with varying window sizes, combined with the DEM slope, were used to classify the study area into six specific types of morphological features (i.e. subtidal channel, intertidal flat, intertidal creek, linear bar, swash bar and beach dune). The developed classification method is adapted and applied to a specific case, but it can also be implemented in other cases and environments.

Beyond innovation. Towards an extended framework for analysing technology policy
Authors: Sørensen Knut Holtan 
Published: January 2017

This paper analyses technology policy as a scholarly concern and political practice that needs to be taken beyond the present somewhat singular focus on innovation and deployment. We also need to include an interest in the making of infrastructure, the provision of regulations, and democratic engagement. Consequently, this paper introduces the concepts of socialisation and domestication to overcome the instrumental, economic framing of technology policy. These concepts highlight the importance of embedding and enacting new technology. The suggested conceptual framework is used in a brief synthetic analysis of four examples of technology policy and technological development in the Norwegian context: cars, wind power, hydrogen for transport, and carbon capture and storage (CCS).
Strife of Brian: Science and Reflexive Reason as a Public Project. An interview with Brian Wynne
Authors: Antonsen Marie , Nilsen Rita Elmkvist 
Published: January 2017

We met Brian Wynne in late April 2013. The place was Hell, Norway, which is nicer than it sounds, especially if you are attending the first Nordic STS Conference. We had recently established NJSTS, and when we heard that Brian Wynne was giving a keynote lecture at the conference, we took the opportunity to interview a pioneer in the field about the so-called political turn in STS. The topics of Wynne`s work rangesfrom technology and risk assessment, public risk perceptions, and public understanding of science, focusing on the relations between expert and lay knowledge and policy decision-making. He has promoted STS and its democratizing potential since the very beginning, and has never been known to shy away from the more controversial aspects of public understanding and engagement in science. Neither did he in this interview: It seems despite his strifes, he is still going with a strong programme.Professor Wynne has addended the interview with some clarifications and references.
Writing Nature
Authors: Asdal Kristin , Ween Gro Birgit 
Published: January 2017

This special issue of the Nordic Journal of Science and Technology Studies is interested in how nature, in different versions and forms, is invited into our studies, analyses, and stories. How is it that we “write nature”? How is it that we provide space for, and actually describe the actors, agents, or surroundings, in our stories and analyses? The articles in the issue each deal with different understandings of both the practices of writing and the introduction of various natures into these. In this introduction to the issue the editors engage with actor-network theory as a material semiotic resource for writing nature. We propose to foreground actor-network theory as a writing tool, at the expense of actor-network theory as a distinct vocabulary. In doing this and pointing out the semiotic origins to material-semiotics we also want to problematize a clear-cut material approach to writing nature.
Prophylactic anticoagulant therapy decreases the incidence of deep vein thrombosis in patients with solid tumors: A systematic review and meta-analysis
Authors: Zhou Yunjiao , Yang Gong , Huang Chenglei 
Published: January 2017

It is not well understood the efficacy and safety of primary deep vein thrombosis (DVT) prophylaxis of anticoagulants in patients with solid tumors. This systematic review and meta-analysis of randomized controlled trials (RCT) determines the relative ratio of primary DVT, survival rate and bleeding events among patients with solid tumors treated with anticoagulants or placebo. Comprehensive literature searches were conducted through the Pubmed, Ovid MEDLINE and EMBASE databases published from January 1st, 1993 to December 31st, 2015. Statistical analysis was performed by RevMan 5.0 software. For DVT events, therisk ratio in 16 trials between the prophylactic and control patients was statistically significant at 0.45 [0.36-0.58]; for major bleeding events, the risk ratio in 18 trials between the prophylactic and control patients was not statistically significant at 1.33 [0.99-1.79], while that in 15 trials with clinically relevant non-major bleeding was statistically significant at 1.83 [1.46-2.30]; the risk ratio for the mortality rate of patients with solid tumors in 16 trials was not statistically significant at 0.97 [0.93-1.02]. Inconclusion, the risk ratio in this meta-analysis showed a significantly reduced incidence of DVT with anticoagulant use. Treatment to patients who had solid tumors with prophylactic anticoagulants enhanced the incidence rate of non-major bleeding but has no significant impact on the incidence rate of major bleeding. No significant differences were found in the mortality outcomes between anticoagulant and non-anticoagulant groups.
Inventory and Distribution of Energy Subsidies of China
Authors: Chen Zhan-Ming 
Published: January 2017

ABSTRACT To provide support for the energy subsidy reform as a critical step of China’s recent energy reform agenda, a comprehensive energy subsidy inventory of China is compiled and the associated distributional effect is investigated in this study. According to the results, the lower boundary estimation of annual energy subsidies of China was 90-202 billion CNY, equivalent to 0.22%-0.37% of GDP or 0.95%-1.21% of government expenditure, during 2010-2014. Thanks to the specific subsidies provided to rural grid construction and transportation, 72% of the energy subsidies were distributed to residents in 2012, while fixed capital and export carried another 13% and 10%. Poorer urban household received higher energy subsidy ratio through dwelling and food expenditures, but lower ratio through transportation and communication expenditures. The overall energy subsidies are slightly regressive, thus adequate reform can narrow wealth gap on the one hand and reduce budgetary pressure on the other.
Rethinking legal protection of the elderly. Report of the second international RETHINKIN. seminar.

Rethinking legal protection of the elderly. Report of the second international RETHINKIN. seminar.
The comparative discussions held during this seminar show that the different jurisdictions make use of – approximately – the same ingredients for their legislation on adult guardianship measures and continuing powers of attorney. Given the common international framework (for example the UN Convention on the Rights of Persons with Disabilities) and given the common societal context (cfr. the strong increase of the ageing population) this may not come as a surprise. Despite these common ingredients, the different jurisdictions have managed to arrive at different dishes spiced with specific local flavours. Given that each jurisdiction bears its own history and specific policy plans, this may not come as a surprise either. The adage ‘same same but different’ is in this respect a suitable bromide.For my own research, the several invitations – that implicitly or explicitly arose from the different discussions – to rethink important concepts or assumptions were of most relevance and importance. A particular example that comes to mind is the suggestion to ‘reverse the jurisprudence’ and to take persons with disabilities instead of healthy adult persons as a point of reference. Also, the invitation to rethink the relationship between the limitation of capacity and the attribution of a guard comes to mind as the juxtaposition of the different jurisdictions showed that these two aspects don’t need to be automatically combined. Also the discussion on the interference between the continuing powers of attorney and the supervision by the court, provoked further reflection on hybrid forms of protection on my part. Finally, the ethical and medical-legal approaches may lead to a reconsideration of the traditional underlying concepts of autonomy and the assessment of capacity.

OPEN en eerlijke omgang met klachten en incidenten in de zorg. Verslag van het eerste jaar van leernetwerk OPEN
Als er iets misgaat in de behandeling van een patiënt is het van groot belang dat daar door de zorgaanbieder openheid over wordt gegeven. Hoe dat het beste kan worden georganiseerd, wordt onderzocht in OPEN. OPEN is een leernetwerk waarin door onderzoekers en ziekenhuizen wordt samengewerkt om meer inzicht te verkrijgen in werkwijzen die openheid na medische incidenten kunnen bevorderen. In deze bijdrage wordt kort toegelicht wat OPEN als leernetwerk inhoudt. Vervolgens wordt uiteengezet wat de verplichtingen van het ziekenhuis inhouden als het misgaat en worden enkele begrippen uitgelegd. Daarna komt aan bod in hoeverre aan die verplichtingen wordt tegemoetgekomen en wordt toegelicht wat er op het niveau van patiënten, zorgverleners en leidinggevenden georganiseerd moet worden voor een open en eerlijke omgang met incidenten in het ziekenhuis.

Freedom of conscience or individual autonomy? Changing views on religious liberty in the Netherlands and Europe
Ideas about the purport and value of religious liberty differ from place to place and can change over time. Over the past fifty years, the trend of secularization has laid the social foundations for a reassessment of religious liberty in the Netherlands. Prompted by the confrontation with Islam, the process of reassessment has gained urgency from, but is also hampered by, terrorist attacks and the migration crisis. However that may be, the result is a prioritization of individual autonomy above freedom of conscience in religious matters. This is borne out by an analysis of parliamentary debates in the Netherlands since 2000 and is explained as part of a broader shift from conscience-based to autonomy-based interpretations of liberalism in Dutch society.

The criminalisation of female circumcision in a comparative law context
In Europe, female circumcision has been considered a grave violation of human rights. However, many European countries fail to combat this illegal practice. This article answers the question why criminal law enforcement with regard to female circumcision seems to fail in various European states, with the exception of France. To answer this question, this article analyses various models of citizenship.
