The Impact on System Performance When Renovating a Multifamily Building Stock in a District Heated Region
Authors: Blomqvist Stefan , La Fleur Lina , Amiri Shahnaz , Rohdin Patrik , Ödlund (former Trygg) Louise
Published: April 2019

In Sweden, 90% of multifamily buildings utilize district heat and a large portion is in need of renovation. The aim is to analyze the impact of renovating a multifamily building stock in a district heating and cooling system, in terms of primary energy savings, peak power demands, electricity demand and production, and greenhouse gas emissions on local and global levels. The study analyzes scenarios regarding measures on the building envelope, ventilation, and substitution from district heat to ground source heat pump. The results indicate improved energy performance for all scenarios, ranging from 11% to 56%. Moreover, the scenarios present a reduction of fossil fuel use and reduced peak power demand in the district heating and cooling system ranging from 1 MW to 13 MW, corresponding to 4–48 W/m2 heated building area. However, the study concludes that scenarios including a ground source heat pump generate significantly higher global greenhouse gas emissions relative to scenarios including district heating. Furthermore, in a future fossil-free district heating and cooling system, a reduction in primary energy use will lead to a local reduction of emissions along with a positive effect on global greenhouse gas emissions, outperforming measures with a ground source heat pump.

Authors: Aguiar-Castillo Lidia , Clavijo-Rodriguez Alberto , De Saa-Perez Petra , Perez-Jimenez Rafael
Published: April 2019

Recycling behavior is an issue that affects the sustainability of many seasonal destinations. The EU promotes projects such as the UrbanWaste that try to study how to avoid the deplorable consequences on cities of this situation. This project has implemented a gamified application, named WasteApp in several European cities, in order to promote the recycling behavior of tourists. This study aimed to verify if the application can be a successful tool to foster recycling and to improve tourism destination reputation. The results show that tourist satisfaction will be influenced directly by the perceived usefulness of the application, and perceived usefulness by the perceived ease of use, but the expectations of the prizes can be counterproductive if they are not perceived as useful for the promoted behavior. Likewise, the satisfaction of the user will influence the recycling behavior, which at the same time improves the reputation of the destination. Besides, the initiative will be visible through word of mouth that is generated from the perceived usefulness, the user’s satisfaction, and the recycling behavior itself. That is, according to this study a gamified application can contribute to the recycling behavior of tourists and improve the image of the destination that adopts it.
Walkability Assessment in a Rapidly Urbanizing City and Its Relationship with Residential Estate Value
Authors: Zhang Jingyuan , Tan Puay Yok , Zeng Hui , Zhang Ye
Published: April 2019

Walkability has increasingly been recognized as an important factor for sustainable urban development that, however, has seldom been investigated in rapid urbanizing cities, especially in the Asian context. This paper assessed walkability in Futian District in the central area of Shenzhen, which has undergone very rapid urbanization within a short period of time. Walkability was assessed for 2013 and 2018 using a walkability index adapted from Walk Score. It was compared with housing prices of 215 randomly selected residential buildings, to further explore the relationships between walkability and residential estate value, provided as one practical application of the assessment of walkability in urban management. Our results show that Futian District has low walkability level, although walkability has been generally improved from 2013 to 2018. A high spatial variation of walkability level within this area was observed in both years. Overall, there was a negative relationship between walkability and housing prices (significant only in 2018), which is inconsistent with studies elsewhere. The results suggest that the housing prices in Futian District are more strongly influenced by other factors rather than by walkability. In addition, the ability of the walkability model to explicitly delineate spatial variation of walkability level makes it a powerful tool to be applied in urban planning and management. Results of this study also have practical applications, which can be used as a reference for residents’ home selection and enable them to make informed decisions in selecting walkable neighborhoods with acceptable prices.
Analysis of the Driving Forces of Urban Expansion Based on a Modified Logistic Regression Model: A Case Study of Wuhan City, Central China
Authors: Luo Ti , Tan Ronghui , Kong Xuesong , Zhou Jincheng
Published: April 2019

Urban development policies and planning schemes are essential drivers of urban expansion in the contemporary world. However, they are usually investigated by qualitative analysis and it is difficult to use them in spatial analysis models. Within the advancement of technology regarding the geostatistical dataset, this study uses a field strength model to quantify policy-oriented factors and designs a modified logistic regression model to analyze the main drivers of urban expansion by selecting natural environment, socioeconomic development, and especially policy-oriented variables. Wuhan City in central China is taken as an example: the modified model is applied and compared with the classical model, and the driving mechanism of urban expansion in Wuhan from 2006 to 2013 is determined through spatial analysis. The results show that the urban system planning in combination with various anthropologic and environmental factors can be comprehensively quantified and described by the urban field strength. The methodological innovation of the classical logistic regression model is tested by statistical and spatial analysis methods, and the results verify that the modified regression model can be used more accurately to investigate the driving mechanism of urban expansion in the past and simulate the spatial pattern of urban evolution in the future.
Exploring a Moderate Operation Scale in China’s Grain Production: A Perspective on the Costs of Machinery Services
Authors: Xu Yu , Xin Liangjie , Li Xiubin , Tan Minghong , Wang Yahui
Published: April 2019

Due to the indivisibility of agricultural machinery in production, limited farm sizes have reduced mechanization efficiency and increased the cost of grain production in China. As a result, the development of a moderate-scale farming system has been proposed by academic communities and policy makers. However, it is still hotly debated how to determine a moderate farm scale. We offer a new perspective on the costs of machinery services. This manuscript employs the threshold model and uses the nationally representative data from the 2015 China Rural Household Panel Survey (CRHPS) to investigate the role of farm size expansion relative to per area machinery services expenditures (PAMSE). The empirical results reveal that there is a nonlinear relation between the farm size and PAMSE. Specifically, farm size expansion can reduce the PAMSE by improving mechanization efficiency in all cases, while the magnitude of cost-saving is progressively reduced in the process of farm scale expansion. In particular, a 1 mu (1 mu = 1/15 ha) increase in the farm scale could only lead to a 0.3% decrease in the PAMSE when the farm size exceeded 50 mu, which indicates that 50 mu is a minimum efficient farm scale to achieve most economies of scale. Therefore, we suggest that persistent efforts should be devoted to improving farmland circulation efficiency and developing scale farms. More importantly, governmental supporting policies, such as agricultural subsidies, need to attach more importance to these large farms.
Analysis of Accident Severity for Curved Roadways Based on Bayesian Networks
Authors: Zhu Lian , Lu Linjun , Zhang Wenying , Zhao Yurou , Song Meining
Published: April 2019

Crashes that occur on curved roadways are often more severe than straight road accidents. Previously, most studies focused on the associations between curved sections and roadway geometric characteristics. In this study, significant factors such as driver behavior, roadway features, vehicle factors, and environmental characteristics are identified and involved in analyzing traffic accident severity. Bayesian network analysis was conducted to deal with data, to explore the associations between variables, and to make predictions using these relationships. The results indicated that factors including point of impact, site of location, accident side of road, alcohol/drugs condition, etc., are relatively critical in crashes on horizontal curves. Accident severity increases when crashes occur on bridges. The sensitivity of accident severity to vehicle use, traffic control, point of impact, and alcohol/drugs condition is relatively high. Moreover, a combination of negative factors will aggravate accident severities. The results also proposed some suggestions regarding the design of vehicles, as well as the construction and improvement of curved roadways.
Eco-Innovation Influencers: Unveiling the Role of Lean Management Principles Adoption
Authors: Leitão João , de Brito Sónia , Cubico Serena
Published: April 2019

This study analyzes the determinant factors of eco-innovation, considering business units with different levels of technological intensity (high technology versus low technology). It aims, in the first instance, to complement the approach on the determinants of eco-innovation in the existent literature by incorporating the novelty related to the analysis of the effects arising from the adoption of the lean management principles. Specifically, it aims to analyze the effects of the previously referred to determinant factors both on the economic performance and on the innovative performance of Portuguese industrial and service companies with different levels of technological intensity (high-tech versus low-tech). The conceptual model presented is of an innovative nature, since it includes four groups of determinant factors present in the literature, namely technology, market, public policies, and cooperation relationships, and adds a fifth group of determinant factors still to be explored empirically concerning the adoption of lean management principles. In the empirical approach, five research hypotheses arising from the literature review are tested, using secondary data collected from the Community Innovation Survey (CIS)—CIS 2010 for a total sample of 334 companies, made up of 95 high-tech companies and 239 low-tech companies. The conceptual model is tested using a logistic regression method, which indicated a suitable accuracy and reliability for the purposes of empirical tests. The empirical evidence confirms that most of the groups of determinants previously identified in the literature have a significant influence on eco-innovation. In addition, the empirical evidence obtained here indicates a positive and significant effect of lean management principles on eco-innovation.
Stagnation Point Flow and Heat Transfer over an Exponentially Stretching/Shrinking Sheet in CNT with Homogeneous–Heterogeneous Reaction: Stability Analysis
Authors: Anuar Nur Syazana , Bachok Norfifah , Arifin Norihan Md , Rosali Haliza
Published: April 2019

This study focuses on the flow of stagnation region and heat transfer of carbon nanotubes (CNTs) over an exponentially stretching/shrinked sheet in the presence of homogeneous–heterogeneous reactions. Kerosene and water are considered base fluids in both single-wall and multi-wall carbon nanotubes. After employing the appropriate similarity variables, the system of partial differential equations is transformed to a system of nonlinear ordinary differential equations. Solution of the problems is obtained numerically using the bvp4c solver in MATLAB software. The impact of physical parameters, such as solid volume fraction, stretching/shrinking parameter, homogeneous and heterogeneous reaction rate, Schmidt number on the velocity, temperature and concentration profiles, skin friction, and heat transfer rate are discussed graphically and interpreted physically. The results indicate that for an exponentially shrinking sheet, dual solutions exist for a certain range. It is clear from figures that the concentration profile increases for increasing values of heterogeneous parameter and decreasing values of homogeneous parameter. Heat transfer and skin friction were observed to have a greater impact for single-wall carbon nanotubes (SWCNTs) compared to multi-wall carbon nanotubes (MWCNTs). A stability analysis has been performed to show which solutions are linearly stable.

Published: April 2019

The lack of rainfall in the Canary Islands′ Archipelago is leading to the depletion of the existing aquifers throughout the islands, above all in the easternmost isles (Gran Canaria, Lanzarote and Fuerteventura). Due to the increasing water demand in the southern area of the Island of Gran Canaria, appropriate planning has become necessary in order to avoid the depletion of the phreatic water resources that can be found there. One of the most affected areas is the Amurga Mountain Range, where the existing aquifers are depleted, as shown in the Hydrological Plan of Gran Canaria. The aim of this study was to characterize the hydrochemistry of the above-mentioned groundwater bodies. Water quality monitoring was carried out over a period of five years, involving the survey of a total of 288 samples (over 4300 tests). The water from those aquifers has the characteristic of being fairly mineralized, with a prevalence of Cl−, Ca2+ and Na+ ions, salinity levels reaching 8646 mg/L, and chloride levels up to 4200 mg/L. The waters of these aquifers can be divided into two basic types, i.e., those containing high levels of sodium chloride, which can be found around the Tirajana Gorge; and the waters rich in magnesium chloride and sodium sulfate in the Arguineguín Gorge, as well as in the Amurga Massif itself.

Published: April 2019

In this study, the prediction interval method was used in simple regression models to filter continuous river surface velocity microwave radar data. To evaluate the model performance, two data sets from monitoring stations with mild and steep channel slopes were used. A human–machine interface software program developed in LabVIEW was used to sample data from big continuous data for establishing the relationships between surface velocity and water level, two surface velocities, and their prediction intervals. Filtering by coupled relationships detected the most noise in the surface velocity and the original data, and the results for different cases were compared. The results were also compared with widely used modern smoothing methods. It was found that raw data cannot always be post–processed using these smoothing methods. Moreover, peaks become distorted. This study provides a method for filtering noise signals in continuous river surface velocity data without data contamination, which makes the surface velocity data more reliable and applicable for advanced studies, such as machine learning applications, and can be applied for the quality control of surface velocity data in the future.
An Improved Integral Model for a Non-Buoyant Turbulent Jet in Wave Environment
Authors: Fang Shuqiao , Chen Yongping , Xu Zhenshan , Otoo Ebenezer , Lu Shiqiang
Published: April 2019

The integral model developed by Chin (1988) for modelling a non-buoyant turbulent jet in wave environment is improved by introducing two new parameters, i.e., the jet spreading rate c1 and the shortening rate pe. The parameter c1 is used to simplify the model by explicitly describing the radial velocity and scalar profiles under the assumption of “instantaneous” Gaussian distribution. By doing so, the governing equations can be easily solved by simultaneously integrating the conservation laws of momentum and scalars across the jet cross-section. The parameter pe is used to shorten the initial length of zone of flow establishment (ZFE), so as to more accurately account for the wave effect on the jet initial dilution near the jet nozzle. The parameters are calibrated by the particle image velocimetry (PIV)-measured data from three groups of jet experiments, i.e., the group of vertical jet towards the wave direction (vertical jet), the group of horizontal jet along the wave direction (co-wave jet) and the group of horizontal jet opposing to the wave direction (op-wave jet). The results show that both parameters are well related to the ratio of jet and wave characteristic velocities in the same group, but it is not able to be generalized among different groups. Under the same wave condition, the value of c1 in the vertical jet is larger than that of the horizontal jets; while the value of pe in the vertical jet is smaller than that of the horizontal jets, which indicates that the jet has a faster decay rate of centerline velocity and a wider width of jet cross-section profile in the near field when it is vertically discharged into the wave environment. With the well-calibrated parameters, the improved model can achieve a higher accuracy than the original model developed by Chin (1988).

EMOÇÃO, REGULAÇÃO EMOCIONAL E COMPORTAMENTO
Authors: Pinto Xavier Vinícius Pereira
Published: April 2019

Em uma perspectiva comportamental emoções são eventos privados e devem ser caracterizados como predisposições de um organismo para ação. Tais ações pré-programadas foram adquiridas ao longo da história evolutiva da espécie, ou seja, uma herança filogenética, mas também, estão sob controle de variáveis ambientais históricas fruto da exposição o indivíduo às contingências. Pessoas adotam estratégias para regular emoções, e a habilidade de fazê-lo compõe uma capacidade altamente adaptativa no repertório humano e ocorrem frente a situações na qual a experiência emocional é avaliada como prejudicial. Via de regra as emoções alvo de regulação são as emoções negativas e busca-se estratégias com o objetivo de influenciar a trajetória da emoção. O artigo em questão trata da definição de emoções e regulação emocional sob a perspectiva de James Gross, apresenta estratégias cognitivas e comportamentais para regulação emocional, e discute à questão de o porquê as pessoas regulam emoções.
Janna Coomans - Food Offenders: Public Health and the Marketplace in the Late Medieval Low Countries
Authors: Coomans Janna
Published: April 2019

In the Low Countries, market squares were the site of numerous threats to public health and efforts to contain them, notably by the officials who inspected, guarded, and protected these spaces. This chapter explores the ways in which urban authorities and other corporate bodies attempted to police markets, and improve levels of sanitation, environmental health, and food safety. It utilizes archival material from several Netherlandish cities, including financial records and public decrees, bylaws, and the statutes of trade and craft guilds (which furnish important evidence about the ways in which medical theories informed attitudes to food standards). An analysis of registered fines and information about the punishment of offenders highlights the tensions that existed between customers, vendors, guilds, and magistrates.

Published: April 2019

DUN06 seismic survey was done in the northern part of the Great South Basin of New Zealand with a total of 3110km of high resolution 2D seismic data by Pacific Titan in 2006. This study focuses on 2D seismic interpretation using Petrel Software to interpret the horizons or geological boundaries of different formations based on the extracted well tops from Toroa well which was drilled in the area of interest. The primary objectives of this study are to deduce the structural and stratigraphic information as well as the trapping mechanism of petroleum system if any. Possible indications of the presence of hydrocarbon were also sorted out. There are seven horizons having age ranging from upper Cretaceous to Eocene. Also, approximately 160 faults were interpreted; with two different strike directions; northwest and northeast striking. Several time and depth structure maps were generated. Upon inspection of the facies on the cross section of the seismic images, they areassumed to be deltaic or river channel deposits. The whole structural deformation is classified as syn-rift and post-rift deformation. The latter is divided into first, second and third post rift event. The first two horizons marked the first post-rift event with transgression followed by a set of delta and river channel indicating regression and second post-rift event. The reservoir unit is determined to be PaleoceneDannevirkeTeurian formation and the Early Eocene Paleocene formation acts as the stratigraphic seal and trap for the reservoir unit.
Realistic On-the-fly Outcomes of Planetary Collisions: Machine Learning Applied to Simulations of Giant Impacts

Published: April 2019

Planet formation simulations are capable of directly integrating the evolution of hundreds to thousands of planetary embryos and planetesimals as they accrete pairwise to become planets. In principle, these investigations allow us to better understand the final configuration and geochemistry of the terrestrial planets, and also to place our solar system in the context of other exosolar systems. While these simulations classically prescribe collisions to result in perfect mergers, recent computational advances have begun to allow for more complex outcomes to be implemented. Here we apply machine learning to a large but sparse database of giant impact studies, which allows us to streamline the simulations into a classifier of collision outcomes and a regressor of accretion efficiency. The classifier maps a four-dimensional (4D) parameter space (target mass, projectile-to-target mass ratio, impact velocity, impact angle) into the four major collision types: merger, graze-and-merge, hit-and-run, and disruption. The definition of the four regimes and their boundary is fully data-driven. The results do not suffer from any model assumption in the fitting. The classifier maps the structure of the parameter space and it provides insights into the outcome regimes. The regressor is a neural network that is trained to closely mimic the functional relationship between the 4D space of collision parameters, and a real-variable outcome, the mass of the largest remnant. This work is a prototype of a more complete surrogate model, that will be based on extended sets of simulations (big data), that will quickly and reliably predict specific collision outcomes for use in realistic N-body dynamical studies of planetary formation.
Implications of Philae Magnetometry Measurements at Comet 67P/Churyumov–Gerasimenko for the Nebular Field of the Outer Solar System

Published: April 2019

The remanent magnetization of solar system bodies reflects their accretion mechanism, the space environment in which they formed, and their subsequent geological evolution. In particular, it has been suggested that some primitive bodies may have formed large regions of coherent remanent magnetization as a consequence of their accretion in a background magnetic field. Measurements acquired by the Rosetta Magnetometer and Plasma Monitor have shown that comet 67P/Churyumov–Gerasimenko (67P) has a surface magnetic field of less than 0.9 nT. To constrain the spatial scale and intensity of remanent magnetization in 67P, we modeled its magnetic field assuming various characteristic spatial scales of uniform magnetization. We find that for regions of coherent magnetization with ≥10 cm radius, the specific magnetic moment is  ≲5 × 10−6

. If 67P formed during the lifetime of the solar nebula and has not undergone significant subsequent collisional or aqueous alteration, this very low specific magnetization is inconsistent with its formation from the gentle gravitational collapse of a cloud of millimeter-sized pebbles in a background magnetic field ≳3 μT. Given the evidence from other Rosetta instruments that 67P formed by pebble-pile processes, this would indicate that the nebular magnetic field was ≲3 μT at 15–45 au from the young Sun. This constraint is consistent with theories of magnetically driven evolution of protoplanetary disks.
Multiple Spiral Arms in Protoplanetary Disks: Linear Theory
Authors: Miranda Ryan , Rafikov Roman R.
Published: April 2019

Recent observations of protoplanetary disks, as well as simulations of planet–disk interaction, have suggested that a single planet may excite multiple spiral arms in the disk, in contrast to the previous expectations based on linear theory (predicting a one-armed density wave). We reassess the origin of multiple arms in the framework of linear theory by solving for the global two-dimensional response of a nonbarotropic disk to an orbiting planet. We show that the formation of a secondary arm in the inner disk, at about half of the orbital radius of the planet, is a robust prediction of linear theory. This arm becomes stronger than the primary spiral at several tenths of the orbital radius of the planet. Several additional, weaker spiral arms may also form in the inner disk. On the contrary, a secondary spiral arm is unlikely to form in the outer disk. Our linear calculations, fully accounting for the global behavior of both the phases and amplitudes of perturbations, generally support the recently proposed WKB phase argument for the secondary arm origin (as caused by the intricacy of constructive interference of the azimuthal harmonics of the perturbation at different radii). We provide analytical arguments showing that the process of a single spiral wake splitting up into multiple arms is a generic linear outcome of wave propagation in differentially rotating disks. It is not unique to planet-driven waves and also occurs in linear calculations of spiral wakes freely propagating with no external torques. These results are relevant for understanding formation of multiple rings and gaps in protoplanetary disks.
Catalog of Decaying Kink Oscillations of Coronal Loops in the 24th Solar Cycle
Authors: Nechaeva Alena , Zimovets Ivan V. , Nakariakov V. M. , Goddard C. R.
Published: April 2019

A catalog of kink oscillations of solar coronal loops, which spans during almost all of solar cycle 24, is presented. The catalog is based on the observations made in the extreme ultraviolet band at 171 Å with Solar Dynamics Observatory/Atmospheric Imaging Assembly and includes parameters of 223 oscillating loops in 96 oscillation events. The catalog provides the information about the oscillation locations, time, and dates of the events, associated flare, initial displacement, oscillation period, exponential damping time, and apparent amplitude. The vast majority of the oscillation detections, 84%, were made in the loops situated near or off the solar limb. The oscillation periods are found to range from 1 to 28 minutes, with 74% of the events that have the period in the range of 2–10 minutes. About 90% of the oscillations have the apparent amplitude in the range of 1–10 Mm. The oscillating loop lengths are 70–600 Mm. The typical apparent amplitude is about 1% of the loop length. The oscillation period scales linearly with the loop length, and the damping time scales linearly with the period, which confirm previous findings. The oscillation quality factor scales with the amplitude to the power of minus 0.7. No statistically significant evidence of correlation was found between both the oscillation period and the mean sunspot number, and the loop length and mean sunspot number. The catalog provides the research community with the foundation for the further statistical study of kink oscillations and their use for coronal seismology.
The Cognitive Effects of Electroconvulsive Therapy: A Critical Review
Authors: Mosti Caterina , Brook Michael
Published: April 2019

In this article, we discuss the neurocognitive domains affected by electroconvulsive therapy (ECT), moderators of ECT-related cognitive change, and cognitive outcomes in high-risk populations, as well as compare the cognitive effects ECT to other common treatments for refractory depression. Despite ECT being one of the oldest and most common treatments for refractory depression, various approaches to ECT (ie, strength, wavelength, and electrode placement), use of clinical convenience samples, and employment of varied and often inadequate methods of neurocognitive assessment have contributed to ongoing confusion regarding the nature and severity of post-treatment cognitive side effects. Although findings suggest that most healthy adults return to neurocognitive baseline within a few days after treatment, older adults and those with premorbid neurological impairment may be at an increased risk of prolonged mental status changes post-ECT. Employment of comprehensive neuropsychological batteries versus screening measures may assist in further understanding the nature and course of post-treatment cognitive side effects.

Difficult diagnosis of Angiomatoid Fibrous Histiocytoma of the leg mimicking a benign condition
Authors: Colangeli Marco , Rimondi Eugenio , Spinnato Paolo , Donati Davide Maria , Manfrini Marco
Published: April 2019

Angiomatoid fibrous histiocytoma is a rarely metastasizing soft-tissue tumor of low-grade malignancy. Here we report a case of angiomatoid fibrous histiocytoma located in the leg of a 15-year-old female. This case is of particular interest due to its radiological features that led to raise two questions concerning the nature of the disease (is it reactive or tumoral?) and its site of origin (within soft tissues or the tibial periosteum?). Here we describe ultrasound, magnetic resonance imaging, computed tomography scan and positron emission tomography findings that helped answer these questions, understand the real nature of the disease and its appropriate treatment. This case shows that a single type of imaging technique may not be sufficient to understand the real nature of a musculoskeletal lesion and that it is necessary to combine all information derived from various imaging techniques in order to correctly diagnose and treat the disease.

D’une part, en guise de tour d’horizon conceptuel, la première section se penche sur les principales définitions des notions d’industries créatives, de ville créative et d’économie créative ainsi que sur diverses perspectives critiques afin de mettre en lumière certains enjeux soulevés par ces notions au niveau théorique. D’autre part, la deuxième section propose une brève analyse critique ayant pour but de discuter des défis liés autant aux politiques culturelles qu’à la mise en œuvre au niveau du commerce international de la Convention sur la protection et la promotion et de la diversité des expressions culturelles (CDEC) dans un contexte marqué par la montée de l’économie et des industries créatives.
Les paradoxes de la précarité dans l’emploi artistique. Le cas des musiciens professionnels au Mexique
Authors: Guadarrama Rocío
Published: April 2019

Cet article explore les dilemmes de l’emploi artistique sur un marché du travail tel que celui du Mexique, où la précarité tend à se normaliser. Nous avons choisi délibérément d’étudier le cas des musiciens professionnels afin de prouver que la précarité, qui se cache sur ces marchés sous le masque de la multiactivité, envahit les niches d’un emploi traditionnellement plus stable. Cependant, la multiactivité est loin de constituer un phénomène immuable, qui serait imposé de façon unilatérale par le contexte social ou les dispositifs institutionnels au sein desquels les individus vivent et travaillent. Il s’agit bien plutôt d’un phénomène processuel et hétérogène ayant une forte composante subjective: à partir de cette prémisse, la recherche ci-dessous met en évidence le rôle actif des sujets tout au long de leur carrière, ainsi que les stratégies professionnelles qu’ils mettent en place, débouchant sur une combinaison variable d’emplois au cours de leur existence.
L’innovation sociale ouverte comme stratégie de gestion de la baisse des subventions dans les organismes communautaires culturels
Authors: Houessou Benjamin , Tremblay Diane-Gabrielle
Published: April 2019

Les organismes communautaires connaissent de plus en plus de difficultés financières de nos jours, entre autres, en raison de la diminution des subventions des financeurs publics ou privés. Dans ce contexte plusieurs de ces organismes abandonnent, modifient tout ou partie de leurs missions ou cherchent de nouvelles orientations. Face à cette problématique, la question principale qui guide notre recherche est la suivante : comment les organismes communautaires montréalais en lien avec leurs parties prenantes gèrent-ils la baisse de subventions ? Pour tenter de répondre à cette question, nous avons réalisé une recherche qualitative sur les orientations que prennent ces organismes dans ce contexte, et en particulier, sur ce que nous pouvons appeler l’émergence d’une orientation culturelle, créative ou artistique dans les organismes communautaires à Montréal. Les résultats montrent que l’innovation sociale ouverte est une stratégie majeure de gestion de la baisse des subventions dans ces organismes communautaires.

A comparison of lognormal and gamma size distributions for characterizing the stratospheric aerosol phase function from OPC measurements
Authors: Nyaku Ernest , Loughman Robert , Bhartia Pawan K. , Deshler Terry , Chen Zhong , Colarco Peter R.
Published: April 2019

Abstract. A series of in situ measurements made by optical particle counters (OPC) at Laramie, Wyoming provides size-resolved stratospheric aerosol concentration data for the period of 2008–2017. These data are analyzed in this study for the purpose of assessing the sensitivity of the stratospheric aerosol phase function to the aerosol size distribution (ASD) model used to fit the measurements. The two unimodal ASD models investigated are the uni-modal lognormal (UMLN) and gamma distribution models, with the minimum χ2 method employed to assess how well each ASD fits the measurements. The aerosol phase function (APF) for each ASD is calculated using Mie theory, and is compared to the APF derived from the Community Aerosol and Radiation Model for Atmospheres (CARMA) sectional aerosol microphysics module. Comparing the χ2 values for the fits at altitudes 20 km and 25 km shows that the UMLN distribution better represents the OPC measurements. The importance of data at aerosol radius below 0.1 μm is also demonstrated: When these data are not available from OPC measurements, the gamma distribution provides a more stable derived APF. The gamma distribution also fits the CARMA model results better than the UMLN model, when the CARMA model results are binned to mimic the OPC measurement bins (and therefore measurements between 0.05 and 0.1 μm are excluded).

Abstract. We report long-term observations of atmospheric parameters in the mesosphere and lower thermosphere (MLT) made over the last two decades. Within this study, we show based on meteor wind measurement, the long-term variability of winds, tides, and kinetic energy of planetary and gravity waves. These measurements were done between the years 2002 and 2018 for the high latitude location of Andenes (69.3° N, 16° E) and the mid-latitude locations of Juliusruh (54.6° N, 13.4° E) and Tavistock (43.3° N, 80.8° W). While the climatologies for each location show a similar pattern, the locations differ strongly with respect to altitude and season of several parameters. Our results show annual wind tendencies for Andenes which are toward the south-west, with changes of up to 3 m/s per decade, while the mid-latitude locations showing smaller opposite tendencies to negligible changes. The diurnal and semidiurnal tides also show different results for each location. Furthermore, the kinetic energy for planetary waves showed strong peak values during winters which also featured the occurrence of sudden stratospheric warming. The influence of the 11-year solar cycle on the winds and tides is presented.

Abstract. Many high and steep slopes are comprised of special topographic and geomorphic
types and formed through mining activities during the construction of mountain expressways.
Severe soil erosion may also occur under heavy rainfall conditions.
Therefore, predicting soil loss on highway slopes is important in protecting
infrastructure and human life. In this study, we investigate Xinhe
Expressway located at the southern edge of the Yunnan–Guizhou Plateau. The
Revised Universal Soil Loss Equation (RUSLE) is used as the prediction model for
soil and water loss on slopes. Geographic information systems, remote
sensing technology, field surveys, run-off plot observation testing, cluster
analysis and co-kriging calculations are also utilised. The partition of the
prediction units of soil loss on the expressway slope in the mountainous
area and the spatial distribution of rainfall on a linear highway are
studied. Given the particularity of the expressway slope in the mountainous
area, the model parameter is modified, and the risk of soil loss along the
mountain expressway is simulated and predicted under 20- and 1-year rainfall
return periods. The following results are obtained. (1) Natural watersheds
can be considered for the prediction of slope soil erosion to represent the
actual situation of soil loss on each slope. Then, the spatial location of
the soil erosion unit can be determined. (2) Analysis of actual observation
data shows that the overall average absolute error of the monitoring area is
0.39 t ha−1, the overall average relative error is 33.96 %
and the overall root mean square error is between 0.21 and 0.66, all of
which are within acceptable limits. The Nash efficiency coefficient is 0.67,
indicating that the prediction accuracy of the model satisfies the
requirements. (3) Under the 1-year rainfall return period condition, we find
through risk classification that the percentage of prediction units with no
risk of erosion is 78 %. The soil erosion risk is low and does not affect
road traffic safety. Under the 20-year return period rainfall condition, the
percentage of units with high and extremely high risks is 7.11 %. The
prediction results can help adjust the design of water and soil conservation
measures for these units.
A obra literária como artefato e ação segundo Roman Ingarden
Authors: Tavares Otávio Guimarães
Published: April 2019

O presente artigo intenta compreender o conceito de obra literária nos textos de Roman Ingarden a partir das noções de artefato e performance, isto é, a obra de arte como uma artificialização e virtualização do real, segundo uma intencionalidade que configura o sentido como um modo de agir ou uma instrução para ação. Para tal, torna-se necessário localizar a filosofia da arte de Ingarden, distanciada de uma filosofia estética e em consonância, a partir dos anos 1960, com a filosofia da arte anglófona, sobretudo no que concerne ao seu foco ontológico e contextualista.
Política de indexação e seus sentidos: um estudo a partir da Análise do Discurso

Published: April 2019

Introdução: A temática da política de indexação é discutida por diferentes autores com o objetivo de aperfeiçoar os processos de indexação para representação e recuperação da informação. Objetivo: Verificar quais são as formulações discursivas atualmente realizadas neste universo e como elas são caracterizadas no contexto da Organização e Representação da Informação. Metodologia: Pesquisa qualitativa e descritiva, analisou-se artigos que abordam a temática política de indexação publicados nos últimos cinco anos, 2011-2016, nos periódicos científicos nacionais na área de “Comunicação e Informação”, que engloba periódicos da Ciência da Informação classificados no Qualis-Periódicos com estratificação A1. A abordagem da Análise do Discurso empregada é a de vertente francesa, tendo como fundamento teórico o arcabouço conceitual de Michel Pêcheux. Resultados: Percebeu-se, por meio da operação de análise, que os enunciados produzidos sobre políticas de indexação podem ser compreendidos como guia e também como filosofia. Conclusão: Os sujeitos buscam por estudos mais aprofundados sobre a temática, visando à melhoria dos processos de indexação em um ideal de qualificação constante, de maneira que a política é vista não só como manual de orientação de processos, mas também como algo que reflete a natureza e cultura organizacional da unidade de informação quanto à Organização e Representação da Informação.
Atores do sistema de comunicação científica: apontamentos para discussão de suas funções

Published: April 2019

Introdução: O sistema de comunicação científica, que é subjacente à comunidade científica, é constituído por diversos elementos e processos, entre os quais seus atores e respectivas funções e atividades. É o resultado das funções e atividades pesquisadores, editoras, bibliotecas, agências de fomento e universidades que contribuem para que a produção, compartilhamento e uso do conhecimento de modo que a ciência possa viabilizada. Objetivo: Identificar as funções e atividades desempenhadas pelos principais atores do sistema de comunicação científica (pesquisadores, editoras, bibliotecas, agências de fomento e universidades). Metodologia: Foi realizado amplo levantamento bibliográfico no Google Scholar, Web of Science e Scopus nos meses de junho e julho de 2015. O levantamento desconsiderou limite temporal e tipo de documento. A estratégia de busca foi a combinação dos termos "pesquisadores", "editoras", "bibliotecas", "agências de fomento" e "universidades" combinados com expressões "comunicação científica”, "informação científica”, “acesso aberto”, “sistema de comunicação”, “comunicação na ciência". Além das buscas terem sido realizadas em língua portuguesa e inglesa, foram adotados termos sinônimos e flexão singular/plural. Após análise preliminar dos textos recuperados e seleção dos textos relevantes, foi elaborada revisão de literatura norteada pelo objetivo de identificar funções e atividades desempenhadas pelos principais atores do sistema de comunicação científica. A revisão assumiu caráter de narrativa e foi estruturada a partir de cada um dos atores. Resultados: Os resultados são apresentados em forma de revisão de literatura narrativa em que foram definidas e identificadas funções e atividades desempenhadas por cada um dos atores do sistema de comunicação científica contemplados no estudo. Conclusões: Por fim, foi elaborado diagrama que representa graficamente tanto as funções e atividades dos atores do sistema de comunicação científica quanto às interações entre eles.

Conclusões: aproximam-se as concepções de “memória multidirecional”, “governança memorial” e a atividade de avaliação documental.
Robo Advice
Authors: Madel Tobias B.
Published: April 2019

With increasing digitalisation, a growing number of institutions are offering financial services online. This book discusses the legal obligations when investment advice or portfolio management services are provided through an automated system, so-called ‘robo advice’. In the first chapter, different types of robo advice are categorised and described. The second chapter focuses on the regulatory classification and the authorisation requirements of such a service. In the third chapter, statutory provisions for robo advice, particularly duties of conduct and organisational obligations, are analysed. Where legal requirements fail to address the specific characteristics of this digital service, the last chapter develops regulatory proposals de lege ferenda.
