Stakeholders’ Interests and Perceptions of Bioeconomy Monitoring Using a Sustainable Development Goal Framework
Authors: Zeug Walther , Bezama Alberto , Moesenfechtel Urs , Jähkel Anne , Thrän Daniela
Published: March 2019

The bioeconomy as an industrial metabolism based on renewable resources is characterized by, not intrinsic, but rather potential benefits for global sustainability, depending on many factors and actors. Hence, an appropriate systematic monitoring of its development is vital and complexly linked to Sustainable Development Goals (SDGs) as well as diverse stakeholder expectations. To structure a framework of the important aspects of such a monitoring system, we conducted a series of stakeholder workshops to assess the relevance of SDGs for the bioeconomy. Our results show how the complexities of these issues are perceived by 64 stakeholders, indicating significant commonalities and differences among six SDGs, including specific interests, perceptions, and, in some cases, counterintuitive and contradictory issues. Eventually, the idea of a bioeconomy is a question of the perception of ends and means of a societal transformation toward holistic sustainability. Global implications like trade-offs, hunger, poverty, and inequalities are aspects of high relevance for monitoring of bioeconomy regions in which they actually do not seem to be substantial.
A Method for the Evaluation of Urban Freight Transport Models as a Tool for Improving the Delivery of Sustainable Urban Transport Policy
Authors: Kaszubowski Daniel
Published: March 2019

The article presents a method which helps local authorities to evaluate urban freight transport models. Given the complex requirements for input data and the inability to supply them for most cities, a proper quantitative evaluation of model functionality may be quite difficult for local authorities. Freight transport models designed to support sustainable urban freight transport objectives are a particular example. To overcome these difficulties, the structure of the method is based on a qualitative analysis of strategic and operational conditions of urban freight management for modelling purposes. A consistent set of criteria is developed to help with parameterising strategic objectives and the analytical requirements of tools to achieve those objectives. The problems of data availability and capture are also included. The method consists of three tiers that are arranged hierarchically to reflect the interrelations. The proposed method was verified against Gdynia’s (Poland) urban freight management requirements. The city was chosen for its early experience of urban freight studies and improvement measures and because it has already defined its strategic objectives. Two comprehensive freight transport models (Freturb and Wiver) and existing city’s transport model were evaluated. The results have ruled out the existing transport model rendering it ineffective as a tool to support urban freight management to meet the city’s strategic objectives. While Freturb turned out to be much better suited for the needs, dedicated models still face a basic barrier of cities having to redesign their systems for collecting urban transport data.
Quantum Fields without Wick Rotation

Published: March 2019

We discuss the calculation of one-loop effective actions in Lorentzian spacetimes, based on a very simple application of the method of steepest descent to the integral over the field. We show that for static spacetimes this procedure agrees with the analytic continuation of Euclidean calculations. We also discuss how to calculate the effective action by integrating a renormalization group equation. We show that the result is independent of arbitrary choices in the definition of the coarse-graining and we see again that the Lorentzian and Euclidean calculations agree. When applied to quantum gravity on static backgrounds, our procedure is equivalent to analytically continuing time and the integral over the conformal factor.

Published: March 2019

The evolution of multipurpose sensors over the last decades has been investigated with the aim of developing innovative devices with applications in several fields of technology, including in the food industry. The integration of such sensors in food packaging technology has paved the way for intelligent food packaging. These integrated systems are capable of providing reliable information about the quality of the packed products during their storage period. To accomplish this goal, intelligent packs use a variety of sensors suited for monitoring the quality and safety of food products by recording the evolution of parameters like the quantity of pathogen agents, gases, temperature, humidity and storage period. This technology, when combined with IoT, is able to provide a lot more information than conventional food inspection technologies, which are limited to weight, volume, color and aspect inspection. The original system described in this work relies on a simple but effective method of integrated food monitoring, right at the client home, suitable for user prepared vacuum-packed foods. It builds upon the IoT concept and is able to create a network of interconnected devices. By using this approach, we are able to combine actuators and sensing devices also providing a common operating picture (COP) by sharing information over the platforms. More precisely, our system consists of gas, temperature and humidity sensors, which provide the essential information needed for evaluating the quality of the packed product. This information is transmitted wirelessly to a computer system providing an interface where the user can observe the evolution of the product quality over time.

Published: March 2019

Infectious bronchitis virus (IBV) and Newcastle disease virus (NDV) are two poultry pathogens seriously affecting the poultry industry. Here, IBV S1 and the ectodomain of NDV F proteins were separately linked with the trans-membrane and carboxy-terminal domain of IBV S protein (STMCT), composing rS and rF; thus, a novel chimeric infectious bronchitis-Newcastle disease (IB-ND) virus-like particles (VLPs) vaccine containing the rS, rF, and IBV M protein was constructed. Under the transmission electron microscope (TEM), VLPs possessing similar morphology to natural IBV were observed. To evaluate the immunogenicity of chimeric IB-ND VLPs, specific pathogen-free (SPF) chickens were immunized with three increasing doses (50, 75, and 100 μg protein of VLPs). Results of ELISAs detecting IBV and NDV specific antibodies and IL-4 and IFN-γ T cell cytokines indicated that vaccination with chimeric IB-ND VLPs could efficiently induce humoral and cellular immune responses. In the challenge study, chimeric IB-ND VLPs (100 μg protein) provided 100% protection against IBV or NDV virulent challenge from death, and viral RNA levels in tissues and swabs were greatly reduced. Collectively, chimeric IB-ND VLPs are highly immunogenic and could provide complete protection from an IBV or NDV virulent challenge. Chimeric IB-ND VLPs are an appealing vaccine candidate and a promising vaccine platform bearing multivalent antigens.

Although antiretroviral therapy (ART) greatly suppresses HIV replication, lymphoid tissues remain a sanctuary site where the virus may replicate. Tracking the earliest steps of HIV spread from these cellular reservoirs after drug cessation is pivotal for elucidating how infection can be prevented. In this study, we developed an in vivo model of HIV persistence in which viral replication in the lymphoid compartments of humanized mice was inhibited by the HIV reverse transcriptase inhibitor 4′-ethynyl-2-fluoro-2′-deoxyadenosine (EFdA) to very low levels, which recapitulated ART-suppression in HIV-infected individuals. Using a combination of RNAscope in situ hybridization (ISH) and immunohistochemistry (IHC), we quantitatively investigated the distribution of HIV in the lymphoid tissues of humanized mice during active infection, EFdA suppression, and after drug cessation. The lymphoid compartments of EFdA-suppressed humanized mice harbored very rare transcription/translation-competent HIV reservoirs that enable viral rebound. Our data provided the visualization and direct measurement of the early steps of HIV reservoir expansion within anatomically intact lymphoid tissues soon after EFdA cessation and suggest a strategy to enhance therapeutic approaches aimed at eliminating the HIV reservoir.

Published: March 2019

Fusarium species are well known for their abundance, diversity and cosmopolitan life style. Many members of the genus Fusarium are associated with plant hosts, either as plant pathogens, secondary invaders, saprotrophs, and/or endophytes. We previously studied the diversity
of Fusarium species in the Fusarium oxysporum species complex (FOSC) associated with Fusarium wilt of banana in Indonesia. In that study, several Fusarium species not belonging to the FOSC were found to be associated with Fusarium wilt of banana. These Fusarium
isolates belonged to three Fusarium species complexes, which included the Fusarium fujikuroi species complex (FFSC), Fusarium incarnatum-equiseti species complex (FIESC) and the Fusarium sambucinum species complex (FSSC). Using a multi-gene phylogeny that included
partial fragments of the beta-tubulin (tub), calmodulin (cmdA), translation elongation factor 1-alpha (tef1), the internal transcribed spacer region of the rDNA (ITS), the large subunit of the rDNA (LSU), plus the RNA polymerase II large subunit (rpb1) and second
largest subunit (rpb2) genes, we were able to identify and characterise several of these as new Fusarium species in the respective species complexes identified in this study.

Configuración narrativa en la franquicia “crossmedia”de Berserk
Authors: Villa Gracia Alberto Daniel
Published: March 2019

La narrativa “crossmedia” en la industria cultural japonesa es un fenómeno que adapta una misma historia a través de distintos formatos, como el cómic, la animación o los videojuegos, entre otros. Aunque el contenido se unifica mediante una serie de elementos comunes, cada medio aporta unas características específicas. El manga es un medio gráfico, estático. El anime es un medio audiovisual, que crea una ilusión de movimiento. Sin embargo, ambos carecen de interactividad por parte de los lectores o espectadores. Los videojuegos, en cambio, ofrecen al público la posibilidad de interactuar con los personajes y elementos de dichas historias. Este artículo trata de averiguar las similitudes y diferencias del aspecto formal narrativo en un caso concreto: el manga de Kentaro Miura, Berserk (1988-en publicación), las últimas adaptaciones cinematográficas que han relanzado la franquicia y el videojuego que siguió a dicha trilogía.
Multi-satellite retrieval of single scattering albedo using the OMI–MODIS algorithm
Authors: Eswaran Kruthika , Satheesh Sreedharan Krishnakumari , Srinivasan Jayaraman
Published: March 2019

Abstract. Single scattering albedo (SSA) represents a unique identification of aerosol
type and can be a determinant factor in the estimation of aerosol radiative
forcing. However, SSA retrievals are highly uncertain due to cloud
contamination and aerosol composition. The recent improvement in the SSA
retrieval algorithm has combined the superior cloud-masking technique of the
Moderate Resolution Imaging Spectroradiometer (MODIS) and the higher
sensitivity of the Ozone Monitoring Instrument (OMI) to aerosol absorption.
The combined OMI–MODIS algorithm has only been validated over a small spatial and
temporal scale. The present study validates the algorithm over global
oceans for the period from 2008 to 2012. The geographical heterogeneity in the
aerosol type and concentration over the Atlantic Ocean, the Arabian Sea and
the Bay of Bengal was useful to delineate the effect of aerosol type on the
retrieval algorithm. We also noted that OMI overestimated SSA when absorbing
aerosols were present closer to the surface. We attribute this overestimation
to data discontinuity in the aerosol height climatology derived from the
Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO)
satellite. OMI uses predefined aerosol heights over regions where CALIPSO
climatology is not present, leading to the overestimation of SSA. The importance
of aerosol height was also studied using the Santa Barbara DISORT Atmospheric Radiative
Transfer (SBDART) model. The results from the joint retrievals were validated
using cruise-based measurements. It was seen that OMI–MODIS SSA retrievals
performed better than the OMI only retrieval over the Bay of Bengal during
winter, when the aerosols are present closer to the surface. Discrepancy between
satellite retrievals and cruise measurements was seen when elevated aerosols
were present which might not have been detected by the cruise instruments.
The effect of hydrophobic glassy organic material on the cloud condensation nuclei activity of particles with different morphologies
Authors: Tandon Ankit , Rothfuss Nicholas E. , Petters Markus D.
Published: March 2019

Abstract. Particles composed of organic and inorganic components can assume
core-shell morphologies. The kinetic limitation of water uptake due to the
presence of a hydrophobic viscous outer shell may increase the critical
supersaturation required to activate such particles into cloud droplets. Here
we test this hypothesis through laboratory experiments. Results show that the
viscosity of polyethylene particles is 5×106 Pa s at
60 ∘C. Extrapolation of temperature dependent viscosity measurements
suggests that the particles are glassy at room temperature. Cloud
condensation nuclei (CCN) activity measurements demonstrate that pure
polyethylene particles are CCN inactive at diameters less than 741 nm and
2.5 % water supersaturation. Thus, polyethylene is used as proxy for
hydrophobic glassy organic material. Ammonium sulfate is used as proxy for
hygroscopic CCN active inorganic material. Mixed particles were generated
using coagulation of oppositely charged particles; charge-neutral
polyethylene–ammonium sulfate dimer particles were then isolated for online
observation. Morphology of these dimer particles was varied by heating, such
that liquefied polyethylene partially or completely engulfed the ammonium
sulfate. Critical supersaturation was measured as a function of dry particle
volume, particle morphology, and organic volume fraction. The data show that
kinetic limitations do not change the critical supersaturation of 50 nm
ammonium sulfate cores coated with polyethylene and polyethylene volume
fractions up to 97 %. Based on these results, and a synthesis of
literature data, it is suggested that mass transfer limitations by glassy
organic shells are unlikely to affect cloud droplet activation near
laboratory temperatures.

Abstract. The growth rate of global methane (CH4) concentrations has a strong interannual variability which is believed to be driven largely by fluctuations in CH4 emissions from wetlands and wildfires, as well as changes to the atmospheric sink. The El Niño Southern Oscillation (ENSO) is known to influence fire occurrence, wetland emission and atmospheric transport, but there are still important uncertainties associated with the exact mechanism and magnitude of this influence. Here we use a modelling approach to investigate how fires and meteorology control the interannual variability of global carbon monoxide (CO), CH4 and ozone (O3) concentrations, particularly during large El Niño events. Using a three-dimensional chemical transport model (TOMCAT) coupled to a sophisticated aerosol microphysics scheme (GLOMAP) we simulate changes to CO, hydroxyl radical (OH) and O3 for the period 1997–2014. We then use an offline radiative transfer model to quantify the impact of changes to atmospheric composition as a result of specific drivers. During the El Niño event of 1997–1998, there were increased emissions from biomass burning globally. As a result, global CO concentrations increased by more than 40 %. This resulted in decreased global mass-weighted tropospheric OH concentrations of up to 9 % and a resulting 4 % increase in the CH4 atmospheric lifetime. The change in CH4 lifetime led to a 7.5 ppb yr−1 increase in global mean CH4 growth rate in 1998. Therefore biomass burning emission of CO could account for 72 % of the total effect of fire emissions on CH4 growth rate in 1998. Our simulations indicate variations in fire emissions and meteorology associated with El Niño have opposing impacts on tropospheric O3 burden. El Niño-related atmospheric transport changes decrease global tropospheric O3 concentrations leading to a −0.03 Wm−2 change in O3 radiative effect (RE). However, enhanced fire emission of precursors such as nitrous oxides (NOx) and CO increase O3 RE by 0.03 Wm−2. While globally the two mechanisms nearly cancel out, causing only a small change in global mean O3 RE, the regional changes are large   up to −0.33 Wm−2 with potentially important consequences for atmospheric heating and dynamics.
Dust mass, CCN, and INP profiling with polarization lidar: Updated POLIPHON conversion factors from global AERONET analysis
Authors: Ansmann Albert , Mamouri Rodanthi-Elisavet , Hofer Julian , Baars Holger , Althausen Dietrich , Abdullaev Sabur F.
Published: March 2019

Abstract. The POLIPHON (Polarization Lidar Photometer Networking) method permits the retrieval of particle number, surface area, and volume concentration for dust and non-dust aerosol components. The obtained microphysical properties are used to estimate height profiles of particle mass, cloud condensation nucleus (CCN) and ice-nucleation particle (INP) concentrations. Of central importance is the conversion of the lidar-derived extinction profiles into aerosol miccrophysical properties (number, surface area, volume). These conversion parameters are determined from Aerosol Robotic Network (AERONET) aerosol climatologies of optical and microphysical properties. In this article we focus on the dust-related POLIPHON retrieval and present an updated set of dust conversion factors considering all relevant deserts around the globe. We apply the new conversion factor set to a dust measurement with polarization lidar in Dushanbe, Tajikistan, in central Asia. Strong aerosol layering was observed with mineral dust advected from Kazakhstan (0–2 km height), Iran (2–5 km), the Arabian peninsula (5–7 km), and the Sahara (8–10 km). POLIPHON results obtained with different sets of conversion parameters were contrasted and discussed in terms of uncertainties.
Phytoplankton calcifiers control nitrate cycling and the pace of transition in warming icehouse and cooling greenhouse climates
Authors: Kvale Karin F. , Turner Katherine E. , Landolfi Angela , Meissner Katrin J.
Published: March 2019

Abstract. Phytoplankton calcifiers contribute to global carbon cycling through their
dual formation of calcium carbonate and particulate organic carbon (POC). The
carbonate might provide an efficient export pathway for the associated POC to
the deep ocean, reducing the particles' exposure to biological degradation in
the upper ocean and increasing the particle settling rate. Previous work has
suggested ballasting of POC by carbonate might increase in a warming climate,
in spite of increasing carbonate dissolution rates, because calcifiers
benefit from the widespread nutrient limitation arising from stratification.
We compare the biogeochemical responses of three models containing (1) a
single mixed phytoplankton class, (2) additional explicit small phytoplankton
and calcifiers, and (3) additional explicit small phytoplankton and calcifiers
with a prognostic carbonate ballast model, to two rapid changes in
atmospheric CO2. The first CO2 scenario represents a rapid (151-year)
transition from a stable icehouse climate (283.9 ppm) into a greenhouse
climate (1263 ppm); the second represents a symmetric rapid transition from a
stable greenhouse climate into an icehouse climate. We identify a slope
change in the global net primary production response with a transition point
at about 3.5 ∘C global mean sea surface temperature change in all
models, driven by a combination of physical and biological changes. We also find that in
both warming and cooling scenarios, the application of a prognostic carbonate
ballast model moderates changes in carbon export production, suboxic volume,
and nitrate sources and sinks, reducing the long-term model response to about
one-third that of the calcifier model without ballast. Explicit small
phytoplankton and calcifiers, and carbonate ballasting, increase the physical
separation of nitrate sources and sinks through a combination of
phytoplankton competition and lengthened remineralization profile, resulting
in a significantly higher global nitrate inventory in this model compared to
the single phytoplankton type model (15 % and 32 % higher for icehouse and
greenhouse climates). Higher nitrate inventory alleviates nitrate limitation,
increasing phytoplankton sensitivity to changes in physical limitation
factors (light and temperature). This larger sensitivity to physical forcing
produces stronger shifts in ocean phosphate storage between icehouse and
greenhouse climates. The greenhouse climate is found to hold phosphate and
nitrate deeper in the ocean, despite a shorter remineralization length scale
than the icehouse climate, because of the longer residence times of the deep
water masses. We conclude the global biogeochemical impact of calcifiers
extends beyond their role in global carbon cycling, and that the ecological
composition of the global ocean can affect how ocean biogeochemistry responds
to climate forcing.
On the future role of the most parsimonious climate module in integrated assessment
Authors: Khabbazan Mohammad M. , Held Hermann
Published: March 2019

Abstract. In the following, we test the validity of a one-box climate model as an
emulator for atmosphere–ocean general circulation models (AOGCMs). The one-box
climate model is currently employed in the integrated assessment models FUND,
MIND, and PAGE, widely used in policy making. Our findings are twofold.
Firstly, when directly prescribing AOGCMs' respective equilibrium climate
sensitivities (ECSs) and transient climate responses (TCRs) to the one-box
model, global mean temperature (GMT) projections are generically too high by
0.5 K at peak temperature for peak-and-decline forcing scenarios, resulting
in a maximum global warming of approximately 2 K. Accordingly, corresponding
integrated assessment studies might tend to overestimate mitigation needs and
costs. We semi-analytically explain this discrepancy as resulting from the
information loss resulting from the reduction of complexity. Secondly, the
one-box model offers a good emulator of these AOGCMs (accurate to within 0.1 K
for Representative Concentration Pathways, RCPs, namely RCP2.6, RCP4.5, and
RCP6.0), provided the AOGCM's ECS and TCR values are universally mapped onto
effective one-box counterparts and a certain time horizon (on the order of the
time to peak radiative forcing) is not exceeded. Results that are based on
the one-box model and have already been published are still just as informative
as intended by their respective authors; however, they should be
reinterpreted as being influenced by a larger climate response to forcing
than intended.

Published: March 2019

O presente trabalho pretende realizar uma investigação histórica sobre as propostas curriculares elaboradas na Escola Ana Vanda Bassara, durante os anos de 1971-1983, em Guarapuava-PR, com o objetivo em perceber como a instituição interpretou a Lei de Diretrizes e Bases da Educação nº. 5.692/71, em vigor durante o período pesquisado. A análise conta com o aporte teórico de Joan Scott (1995) que fornece subsídios para a compreensão e utilização do uso do gênero como categoria de análise. Entre as fontes selecionadas, currículo, livros ata e legislação, acredita-se que junto ao uso da categoria gênero, é possível compreender parte das tensões socioculturais do período, e de como a escola inserida em um espaço instituído por meio das diferenças e desigualdades de gênero, contribuiu para o reforço de tais assimetrias.

A study on a class of modified Bessel-type integrals in a Fréchet space of Boehmians
Authors: Al-Omari Shrideh Khalaf
Published: March 2019

In this paper, an attempt is being made to discuss a class of modified Bessel- type integrals on a set of generalized functions known as Boehmians. We show that the modified Bessel-type integral, with appropriately defined convolution products, obeys a fundamental convolution theorem which consequently justifis pursuing analysis in the Boehmian spaces. We describe two Fréchet spaces of Boehmians and extend the modifid Bessel-type integral between the diferent spaces. Furthermore, a convolution theorem and a class of basic properties of the extended integral such as linearity, continuity and compatibility with the classical integral, which provide a convenient extention to the classical results, have been derived

Purpose: To assess nurses’ perceptions about the transformational leadership applied in psychiatric hospitals and to investigate factors that influence these perceptions. Materials and methods: A descriptive study was conducted in a psychiatric hospital and a psychiatric ward of a general hospital located in a city of Cyprus. A convenience sample of 95 nurses was used, while the Greek version of the « Kuopio University Hospital Transformational Leadership Scale (KUHTLS) questionnaire was used as an instrument. Results: Appreciation, decision making fairness, and individuality were the variables with the highest mean values. Women had significantly higher scores in appreciation, justice, and individuality compared to men. Nurses who were >45 years old had a significantly higher score compared to those who were 31-45 and <30 years old in the subscales decision making (p=0.005), appreciation (p=0.043), development (p=0.020), work efficiency and outcomes (p=0.030). Head and senior nurses had significantly higher scores regarding subscales decision making (p=0.003), appreciation (p=0.025), development (p=0.010), work efficiency and outcomes (p=0.004). Nurses with > 7 years of work experience, had significantly higher scores in fairness subscale compared with the nurses who had less than seven years of work experience (p=0.034). Conclusions: Nurses working in those psychiatric hospitals and ward had positive perceptions about transformational nursing leadership. Hospital administrators should facilitate training programs for nurse managers in leadership styles and their effects on job satisfaction.

Validation and application of a chromatographic method for evaluation of commercial vegetable oils possibly adulterated
Authors: Araújo Katarynna Santos , Barbosa Mariana Oliveira , Malafaia Carolina Barbosa , Napoleão Daniella Carla
Published: March 2019

A method of separation, identification and quantification of fatty acid methyl esters (FAMEs) was developed by gas chromatography with flame ionization detector (GC-FID) using a basic transesterification. In this sense, there were analyzed FAMEs in commercial samples of vegetable oils from soybean and olive oil. The referred method was linear (r>0.99), accurate and precise for palmitic (C16:0), linoleic (C18:2), oleic (C18:2), linolenic (C18:3) and stearic (C18:0) acids. The limits of detection (LOD) and quantification (LOQ) were from 0.03 to 0.31 and 0.08 to 0.94 mg.mL-1 for the five fatty acids, respectively. The results demonstrated that the unsaturated fatty acids were the most abundant for the two samples, being the oleic acid (C18:1) the major in three brands of olive oil (D, E and F), and the linoleic acid (C18:2) the most abundant in soybean oil and the other brands of olive oil (G, H and I), suggesting a possible adulteration in these brands. The proposed method could be considered a tool for the investigation of adulteration in commercial vegetable oils for guaranteed reliability in the results to be comparable with correlated legislations.

El año 1822 supone el cambio de rumbo en la políticaultramarina, basada en la negociación y el entendimiento comoúltima esperanza de salvaguardar la integridad del Orbe Hispánico.Este cambio se encabezó desde las Cortes españolas que, conscientesdel final inevitable que la política de enfrentamiento con los disidentesiba a producir, encomendaron al Ejecutivo enviar a América comisionadospara oír y recibir propuestas de los Gobiernos disidentesde Ultramar, siempre que fuera acorde con la dignidad y el decoro dela Nación, para conseguir la tan ansiada pacificación de Ultramar.Esta encomienda tan trascendental y difícil se vio truncadapor múltiples factores, pero no por ello se puede perder de vista elenorme valor histórico y jurídico que implicaba englobar en pie deigualdad a una gran parte del mundo bajo dominio europeo, en estecaso español, a la senda constitucional.The year 1822 represents a change of direction in theultramarine policy, based on the negotiation and the understanding as last hope to safeguard the integrity of the Hispanic Orb.

El «vigilantismo » como reflejo del fracaso del sistema jurídico-penal estadounidense en los años setenta: análisis de la película «Death Wish» (El justiciero de la ciudad)

El Vigilantismo es una corriente ideológica que propugnael derecho a la autodefensa de los individuos cuando el Estadono es capaz de proporcionársela de manera eficaz. Experimentó unconsiderable auge en los Estados Unidos a partir de los años setenta,presentándose como una alternativa válida en la lucha contra la elevadacriminalidad. El Vigilantismo defiende una visión eminentemente punitivade la Justicia. La película «Death Wish», de Michael Winner (ParamountPictures, 1974), y protagonizada por Charles Bronson, en el papelde Paul Kersey, retrata de forma certera esta doctrina.Vigilantism is an ideological stream that advocates theright to self-defense of the individuals when the Government is unableto provide it effectively. It underwent a considerable boom inthe United States from the 1970s, posing as a valid alternative in thefight against high rates of criminality. Vigilantism defends an essentialpunitive vision of Justice. The film «Death Wish», directed byMichael Winner (Paramount Pictures, 1974), with Charles Bronson,playing the role of Paul Kersey, is an acute portrait of this doctrine.
La protección del estatuto de ciudadanía de la Unión en la última jurisprudencia del TJUE: a propósito de los asuntos Rendón Marín (c-165/14), Chávez-Vílchez (c-133/15) y Toufik Lounes (c-165/16)

El TJUE en la Sentencia Ruiz Zambrano otorgaba, sobrela base del art. 20 TFUE, una «protección genuina» a los ciudadanosde la Unión, menores de edad, con respecto al Estado miembrode su nacionalidad sin haber ejercido previamente su derecho ala libre circulación y, por ende, los Estados no podían denegar el derechode residencia a los nacionales de terceros países, progenitoresde ciudadanos menores de ese Estado miembro. La jurisprudenciamás reciente del TJUE, concretamente, los asuntos Rendón Marín(C-165/2014), Chávez-Vílchez (C-133/15) y Toufik Lounes (C-165/16),abordan la protección del estatuto de ciudadano de la Unión perodesde una nueva perspectiva y con nuevos matices y aportacionesinteresantes, al no centrar tanto su razonamiento en el riesgo de expulsión,sino que, de un lado, atribuye a la aplicación del principiode interés superior del niño un carácter central en el examen de laproblemática jurídica (asuntos Rendón Marín y Chávez-Vílchez) y deotro, reconoce un derecho derivado bajo el ejercicio de la libre circulación,al cónyuge de un ciudadano de la Unión que se muda a otroEstado miembro y en el que obtiene la nacionalidad (asunto ToufikLounes).The CJEU in the Ruiz Zambrano Sentence granted,on the basis of art. 20 TFEU, a «genuine protection» to citizens ofthe Union, infant minors, with respect to the Member State of theirnationality without having previously exercised their right to freemovement and, therefore, the States could not deny the right of residencefor third-country nationals, parents of infant minor citizens ofthat Member State. The most recent jurisprudence of the CJEU, specifically,the cases Rendón Marín (C-165/2014), Chávez-Vílchez (C-133/15) and Toufik Lounes (C-165/16), address the protection of thestatus of citizen of the Union but from a new perspective and withnew nuances and interesting contributions, not focusing its reasoningon the risk of expulsion, but, on the one hand, it attributes to theapplication of the principle of the child’s best interest a central characterin the examination of the legal problematic (Rendón Marínand Chávez-Vílchez cases) and of another, recognizes a derived rightunder the exercise of free movement, the spouse of a Union citizenwho moves to another Member State and obtains nationality (ToufikLounes case).
Boundary Layer Transition Models for Naval Applications: Capabilities and Limitations

Published: March 2019

We describe the implementation of several recently developed boundary layer transition models into the overset computational fluid dynamics code, REX, developed at the University of Iowa, together with an evaluation of its capabilities and limitations for naval hydrodynamics applications. Models based on correlations and on amplification factor transport were implemented in one- and two-equation Reynolds-averaged Navier-Stokes turbulence models, including modifications to operate in crossflow. Extensive validation of the transition models implemented in REX is performed for several 2- and 3-dimensional geometries of naval relevance. Standard tests with extensive available experimental data include flat plates in zero pressure gradient, an airfoil, and sickle wing. More complex test cases include the propeller, P4119, with some experimental data available, and the generic submersible, Joubert BB2, with no relevant experimental data available, to validate the transition models. Simulations for these last two cases show that extensive regions of laminar flow can be present on the bodies at laboratory scale and field scale for small vessels, and the potential effects on resistance and propulsion can be significant.

1. Introduction

Progress for prediction of attached, fully turbulent flows for practical aerodynamic and hydrodynamic applications has reached a relatively mature plateau. However, according to a recent comprehensive review of pacing items (Slotnick et al. 2014), the single largest hurdle for incorporating computational fluid dynamics (CFD) into the design process in the near future is the ability to accurately predict turbulent flows with boundary layer transition and separation. Transition can impact skin friction, heat transfer, noise, propulsion efficiency, and maneuverability. This is especially true at model scale and for small craft such as unmanned or autonomous surface and underwater vehicles.
Politisk idéhistorie: Fire tilgange
Authors: Thorup Mikkel
Published: March 2019

The article discusses the importance of ideas for political analysis. Ideas are more than random or inconsequential rationalisations of hard interests. They constitute and effect something in and of themselves. The article therefore presents the four most important and influential approaches to the study of the history of political thought: Michel Foucault’s discourse analysis, Michael Freeden’s ideology analysis, Quentin Skinner’s legitimization analysis and Reinhart Koselleck’s conceptual history.
Les actionnaires, le voile corporatif et les tiers : quelques réflexions sur l’arrêt Houle c. Banque Canadienne Nationale et la véritable nature de ces rapports
Authors: Turgeon Jean
Published: March 2019

L’auteur examine la nature véritable des rapports pouvant exister entre les tiers et les actionnaires d’une personne morale et remet en cause la position traditionnelle voulant qu’il n’y ait pas de liens contractuels entre eux. Il peut en effet exister des liens contractuels directs dans le cas de sociétés fermées où les actionnaires sont étroitement liés aux activités de la société. Il pourra donc arriver qu’un acte d’un tiers, résultant d’un contrat de ce dernier avec la société, puisse engendrer une responsabilité contractuelle du tiers envers les actionnaires. Toutefois, cela ne signifie pas pour autant que les actionnaires ont de ce fait un recours direct contre le tiers. Ce recours ne sera permis que dans des circonstances précises.
De la phase préalable à la formation de certains contrats
Authors: Guillemard Sylvette
Published: March 2019

La plupart des droits nationaux régissent la formation « classique » des contrats. Cependant, il existe d’autres modalités de formation des conventions. Ainsi, les contrats conclus dans le cadre du commerce international présentent parfois des particularités au stade de la période précédant la conclusion du contrat. Le but de ce texte est d’étudier plus spécifiquement la phase précontractuelle, en analysant juridiquement tant le processus lui-même que les ententes qui le jalonnent et ce, à la lumière de différents systèmes juridiques.
La réforme du Sénat : une nécessité dans la perspective d’une véritable Confédération Canada-Québec
Authors: Resnick Philip
Published: March 2019

Dans ce court texte, l’auteur montre les origines de la demande d’une réforme du Sénat dans l’ouest canadien. Il essaie ensuite de donner trois arguments en faveur d’un Sénat élu : a) renforcer la légitimité de nos institutions centrales; b) jouer un rôle de regard en ce qui touche une éventuelle charte sociale; c) maintenir l’unité du Canada anglais advenant un arrangement confédéral entre le Québec et le reste du Canada. Il conclut, enfin, qu’un Sénat élu sera un moyen d’arriver à une démocratie plus participative et cohérente au Canada.

Esophageal cancer is one of the most common tumor in the world, and the morbidity rate is as high as 100/100 000 in some parts of China. Therefore, it is important and urgent to explore the pathogenesis of esophageal cancer and find new therapeutic targets for esophageal cancer. In this study, we found that a novel tumor suppressor SPINK5 is significantly reduced in the development of esophageal cancer, and is closely related to the pathological differentiation and lymph node metastasis of esophageal cancer via bioinformatics analysis and esophageal cancer tissue array. Further studies have found that SPINK5 is closely related to Wnt/β‐catenin signaling pathway by bioinformatics analysis and western blot. In esophageal cancer cells, SPINK5 overexpression can inhibit Wnt/β‐catenin signaling pathway. Combined with LiCl or MG‐132 treatment, SPINK5 can inhibit GSK3β phosphorylation and promote β‐catenin protein degradation, thus inhibit Wnt/β‐catenin signaling pathway. In vivo study, SPINK5 overexpression can significantly inhibit the growth of esophageal cancer cells. Our study shows that SPINK5 can inhibit the proliferation, migration, and invasion of esophageal cancer cells by inhibiting Wnt/β‐catenin signaling pathway, and thus plays an important role in the development of esophageal cancer, and may serve as a treatment target of esophageal cancer.
