Conceptual model of productivity bot for smart construction planning
Authors: Kavaliauskas Donatas , Sakalauskas Leonidas
Published: December 2019

One of the most important tasks in modern construction is to build a building according to the desired time
schedule. This requires a timetable for the construction stages processes. The schedule is also easy to adapt and to plan
the renovation of a building or maintenance works. Without a good schedule site manager cannot effectively handle
construction area processes. The solution to this problem is the proposed productivity bot concept based on metaheuristic
algorithms. Metaheuristic algorithms allow to improve the construction planning process schedules compared with conventional planning methods and equipment. The results of testing with construction planning data has shown that the
metaheuristic algorithm achieved the main improvements during the first planning optimization stages. The proposed
concept is expected to present results that are close to the optimal timetable and surpass classical methods for scheduling.
Productivity bots act as a software engine complementing with the organization of construction or automation functionality. Productivity bot is designed to manage building processes. It is intended for automated planning of construction
stages schedules according to construction technologies.
Change of soil mechanical properties due to triaxial sample size
Authors: Skuodis Šarūnas , Dirgėlienė Neringa , Lekstutytė Ieva
Published: December 2019

Triaxial test is widely used to determine the behaviour and strength parameters of soil. Several consolidated
drained triaxial compression tests were performed on two specimen sizes of sand and clay. This article investigate and
compares the influence of specimen size and scale effect on the soil shear strength. The tests results show that the shear
strength parameters are influenced by the clay specimen size. The results indicate that the effect of triaxial clay sample
size is more significant with higher confining pressures. The second type of tests carried out on sand samples shows that
sample size doesn‘t influence the results of the shear strength. Author’s show that clay analyses can be significantly
affected by the choice of the specimen size used to determine shear strength parameters.

Authors: Jaskulski Roman , Kubissa Wojciech
Published: December 2019

The article presents the results of investigations of the compressive strength of controlled low-strength materials (CLSM) prepared with the use of copper slag waste as a filler. Eighteen mixtures were made of which part with
sole copper slag waste, part with sand which served as reference and mixtures in which half of the filler was sand and
half the copper slag waste. Part of them was prepared with 60 kg/m3 of cement and another part with 40 kg/m3 of cement.
As a supplementary binder conventional fly ash was used. The aim was to recognie the feasibility of this type of material
using copper slag waste as filler. Compressive strength tests were performed on the specimens in form of
40×40×160 mm bars. The tests showed that after meeting certain conditions regarding the composition of the mixture,
the copper slag waste can be used as a filler in CLSM. The compressive strength values after 180 days not exceeded
1.60 MPa which is a very good result for this kind of material.

Authors: Półka Marzena , Białek Jan
Published: December 2019

The paper presents the results of tests for smoke optical density conducted on four various floor panels of
building interior design. As regards safety, wood base or polymeric panels are flammable materials, and their ignitability and smoke generation depend to a large extent on its chemical composition, density and thickness of element.
Smoke emission is one of basic elements that characterise the fire environment. Consequently the objective of the paper was to carry out a comparative analysis of smoke generation of chosen floor panels at selected thermal expositions
and at the presence or absence of a stimulus igniting the volatile gaseous phase (pilot flame). For needs of experimental research use was made of: samples (oak board), wood-based materials (two type of HDF panels) and PVC
floor panel. Experimental research has been carried out based on the standard PN ISO 5659 – 2:2013-06. The tests results were compared with international optical smoke density requirements for the interior design of ships and trains.
Free vibration of rectangular nanoplate strips
Authors: Lellep Jaan , Hossain Mainul
Published: December 2019

Natural vibrations of nanobeams and nanosheets are investigated with the help of nonlocal theories of elasticity. The vibration analysis is based on the size-dependent non-local theory of elasticity developed by A. C. Eringen. It is assumed that the nano-structures under consideration have rectangular cross sections with piece wise constant dimensions and that the nanoplates are weakened with defects. The influence of the crack on the vibration of the nanoplate is assessed with the aid of additional local compliance developed in previous papers. Numerical results are presented for one- and two-stepped nanoplates.

The article presents the results of the survey aimed to analyze the attitude and perceptions regarding the use
of BIM for data handling and analysis. Two target groups were researched, according to the role they play in building
processes, namely public administrations (including tenants, owners, and building administrators) and Professionals
(engineers / architects). The study conducted during the Net-UBIEP (Network for Using BIM to Increase the Energy
Performance) project. The purpose of this study was to assess the implementation of building information modeling
(BIM) as a tool and a process among key stakeholders in order to understand the current use of BIM, benefits of using
BIM, obstacles of using BIM as well as possible future use. This study can be used as a pre-analysis of feedback from
building users and construction professionals and can contribute to the co-adaptation process between BIM knowledge
providers and BIM users.
Wall blocks based on the aggregates from plant wastes
Authors: Dalzhonak Andrei , Bakatovich Aliaksandr
Published: December 2019

The article considers the possibility of using agricultural waste in the development of new building materials
in the form of wall blocks. When selecting the compositions, the ideal fractions and ratios of straw to flax were determined, providing the forming of the densest frame of coarse and fine aggregates. Cement and lime were used as a binder.
The effect of humidity on the durability and thermal conductivity of straw wall blocks and straw flax boon blocks were
investigated. The conditions for the possible occurrence of mold on the block surface of aggregates were studied. According to the results of full-scale tests, the obtained dependencies of the temperature distribution during the coldest
period of the winter season were analyzed and the high insulating ability of wall blocks was confirmed. The dependencies of the distribution of humidity over the thickness of the wall blocks after the end of the winter season testing
operations were revealed. As a result of the research, a solution for the rational use of plant waste building wall blocks
was proposed. The blocks can be applied to the construction of load-bearing and nonload-bearing walls in one-story
buildings and multi-story frame construction when filling exterior wall openings.

Published: December 2019

Dry Building Mortars (DBM) are new in terms of building technology, and they sometimes substitute
different kinds of concrete and mortar mixes. DBM have been successfully used in construction and their performance
has been as efficient as the one of commercial mortar mixes, i.e. they boost labour efficiency, and bring down material
consumption. They can be also kept in stock for a long time, and shipped with no compromise in quality. Today DBM
are based on cementing components. And some famous mix mortars are based on gypsum, polymer, and some other
types of cementing components which contain fine-dispersed additives of ground slag, fly ash, and raw sludge. These
mix mortars are applied as smoothing, aligning, waterproof, and safety types of coverage.
This article studies the possibility of involving slag cementing components in manufacturing DBM. Due to their high
waterproof resistance in salt-affected water, these sorts of mixes may be used as protective coatings and plasters for
concrete frames in corrosive medium. Slag Cementing Components (SCC) are hydraulic cementing agents, which
harden both in water and in open air. They are produced by mixing electric-furnace slag or furnace clinkers with some
solutions of alkaline metals (to trigger alkaline reaction), or by mixing together all these agents.

Published: December 2019

Decreased strength of building materials as a result of flame impingement (e.g. during a fire) is one of major
threats in the construction branch. For these reasons, the effectiveness of fire safety systems in various kinds of facilities
or structures is extremely important. One of the determinants of this effectiveness is so-called fire insulation, i.e. time
expressed in minutes after which an increase in the temperature of a protected structure or facility exceeds a certain
admissible value (140 °C). The results of investigations presented in the article concern the determination of the effect
of various mineral binders used in the manufacture of insulation boards from expanded perlite on fire resistance and, in
consequence, on extending the time of fire insulation in the conditions of cellulose and hydrocarbon fire. The conducted
research has revealed that the fire resistance of perlite products can be modelled by selecting adequate mineral binders,
with respect to specific applications and economic considerations. Insulation boards based on expanded perlite – depending on the binder used – were characterized by a fire insulation ranging (with a board thickness of 50 mm) from 50
to 100 minutes in the conditions of cellulose fire and from 20 to 30 minutes in the conditions of hydrocarbon fire.

Published: December 2019

Adhesive bonding is commonly used in the automotive and aerospace industry, where it has proved its
advantages. Nowadays, the bonded joints are starting increasingly used in civil engineering, where they can be applied
in façade structure. Traditionally used structural silicones are resistant to the external environment, but their low strength
and elasticity do not meet the requirements of civil engineering. The greater spread of higher strength adhesives such as
acrylates or polyurethanes is hampered by the lack of knowledge of their ageing resistance. The paper is focused on the experimental
analysis of a double-lap shear joints of Silane Terminated Polymer (STP) adhesive applied in joints with aluminium and
Zn-electroplated steel substrates with various surface treatments. The specimens were exposed to artificial ageing
according to the technical regulations of the Timber Research and Development Institute in Prague. According to this
regulation, specimens were exposed to changing of high and low temperatures, UV-radiation and humidity. This ageing
should simulate 5 years in the climatic environment of Central Europe. Specimens exposed to laboratory ageing are
compared with reference set of test specimens that were not artificially aged. STP demonstrated excellent
resistance to laboratory ageing.
How to help the choice of waterproof insulation to be sustainable?
Authors: Ginda Grzegorz
Published: December 2019

Buildings serve different purposes which are denoted as functions. Function of buildings is ensured by the
application of adequate structural and formal means. Contemporary buildings are of complex nature, therefore, and
consist of diverse components which play specific roles. Besides, some of them are crucial for a specific structural,
functional or formal purpose while other play rather secondary role. Insulation is one of the most important building
components. This is because it is accountable for proper protection of structural building components against negative
influences of external and internal climate conditions. It also provides necessary means for occupational safety and
comfortable building exploitation. Waterproof insulation belongs to one of the most accountable building components.
It is mainly applied for the protection of a building interior against water inflow from the surrounding atmospheric and
underground environment. It nevertheless can be also applied for different reasons e.g. for protecting partitions in wet
compartments against getting wet. Diversity of waterproof insulation application purposes results in a considerable
number of technical and technological insulation solutions. Such diversity makes the choice of the proper waterproof
insulation a hard task. Moreover, the implementation of circular economy idea makes insulation choice even a more
difficult problem. This is why the application of specialised approaches for supporting decision with this regard is
welcome. A proposal for such approach is presented in the paper. The approach may benefit from the application of
different decision support tools. A specific implementation of the approach is finally discussed. The implementation
makes effective use of some renowned decision support tools. The comprehesive and universal nature of the proposed
approach makes it also suitable for other specific purposes e.g. reliable bid selection.

In a modern civil engineering, it is important to erection construction in extremely complicated and difficult
environmental conditions. Additives and admixes to concrete enable to achieved higher mechanical properties
of concrete mixtures. This operation causes, the constructions accomplish durability in various environmental conditions. In the article, authors described scientific research made on concrete with additives: latex based polymer and
microspheres. The tested additives were used in to different proportion each and they were combined with each other.
The aim of research was to determine influence this two additives on compressive strength after 28 days, after 90
days, a tensile splitting strength, a sorptivity, a freeze-thaw resistance and a compressive strength on the specimens
after freeze-thaw resistance test. Received results clearly show decrease in compressive strength of the modified concrete mixtures. The specimens prepared without additives achieved the highest compressive strength results.The researchers observed also increasing liquidity of concrete mixtures and decreasing sorptivity of hardener
concrete under the influence of latex based polymer. The knowledge of basic properties of microspheres from
co-combustion of coal is fundamental to its effect usage of building industry.
Numerical investigation on dynamic response of a steel lattice tower under various seismic events
Authors: Falborsk Tomasz , Lasowicz Natalia
Published: December 2019

The present paper presents the results of the numerical study designed to investigate the soil-structure flexibility effects on modal parameters (i.e. fundamental frequencies) and time-history analysis response (represented by the top relative displacements) of a 46.8 m high steel lattice tower subjected to a number of ground motions including also one mining tremor. In addition to the fixed-base condition, three different soil types (i.e. dense soil, stiff soil, and soft soil) were considered in this investigation. Site conditions were characterized by their average effective profile velocities, Poisson’s ratios, and finally mass densities. Soil-foundation flexibility was introduced using the spring-based approach, utilizing foundation springs and dashpots. The first step was to investigate the influence of different base conditions on modal parameters of the steel lattice tower. In the final part of the current study time-history analysis was performed using different two-component ground motion records (in two horizontal, mutually perpendicular directions). The results obtained indicate that modal parameters and dynamic response of the structure may be considerably affected by the soil-structure interaction effects. Therefore, the present paper confirms the necessity of utilizing soil-flexibility into numerical research.

Authors: Moukannaa Samira , Nazari Ali , Bagheri Ali , Loutou Mohamed , Hakkou Rachid
Published: December 2019

The present study investigates the thermal behaviour of phosphate sludge-based geopolymers. Phosphate
sludge which is a by-product from phosphate beneficiation processes was activated using the alkaline fusion method
to improve the geopolymer activity of this material. Then, the mechanical properties as well as the thermal behaviour
of the resulted geopolymer mortar were studied. The effect of sodium hydroxide addition and fusion temperature on
the mechanical properties and the thermal behaviour of the geopolymers were assessed using compressive strength
tests before and after thermal shock cycles at different temperatures (350, 500, 650 °C). The mineralogical composition of the fused materials was investigated using XRD measurement and the microstructure of the geopolymer mortars was studied using FTIR. The obtained results showed that NaOH content as well as the temperature of fusion are
essential parameters controlling the structure and the strength of the developed geopolymeric gel. Exposure to elevated temperatures up to 650 °C induces a decrease in compressive strength between 58 and 71%. However, a further increase in the temperature of exposure till 800 °C induces a development of compressive strength. Overall, geopolymers with good compressive strength up to 40 MPa could be synthesized in the optimum conditions of fusion: 10% of
NaOH and 550 °C.

Published: December 2019

Concreting is generally a manual, labour intensive and time-consuming process, putting additional burden on
constrained resources. Current practices of concreting are wasteful, non-sustainable and end products usually lack proper
quality conformance. This paper, as the first outcome of an ongoing research project, proposes concrete as an area ripe
for being disrupted by new technological developments and the wave of automation. It puts forward arguments to show
that The Internet of Things (IoT), as an emerging concept, has the potential to revolutionize concreting operations,
resulting in substantial time savings, confidence in its durability and enhanced quality conformance. A conceptual
framework for a digital concrete quality control (DCQC) drawing upon IoT is outlined; DCQC facilitates automated
lifecycle monitoring of concrete, controlled by real-time monitoring of parameters like surface humidity, temperature
variance, moisture content, vibration level, and crack occurrence and propagation of concrete members through embedded sensors. Drawing upon an analytical approach, discussions provide evidence for the advantages of adopting DCQC.
The proposed system is of particular appeal for practitioners, as a workable solution for reducing water, energy consumption and required man-hours for concreting procedures, as well as, providing an interface for access to real-time
data, site progress monitoring, benchmarking, and predictive analytics purposes.
The workability kinetics of phosphogypsum binder

Published: December 2019

The dihydrate phosphogypsum (PG) based binder workability kinetics were investigated regarding to waterbinder ratio (W/B) and chemical admixtures added to the composition of PG paste. PG was dried at 60 °C and homogenized to powder like particles with collision milling in disintegrator and calcium sulphate hemihydrate was obtained
by heating PG at 180 °C. The obtained binder chemical, mineralogical and technological properties were tested and
compared to commercial gypsum plaster. Early age (2 h) and 14 d compression strength was determined. The workability and setting time of both – PG and commercial gypsum was investigated with viscosimeter, ultrasonic pulse velocity and Vicat apparatus and correlation between testing methods was obtained. Results indicate that binder based on
PG has slightly lower pH (pH 6.3) than commercial binder (pH 6.8) and finer particle size grading leading to increased
W/B ratio and more rapid initial setting time. The set retarder could efficiently increase the setting time of PG binder
giving extra workability time which is positive factor for prolonged treatment of binder slurry, i.e. to prepare porous
gypsum binder. Such approach would give a safer alternative to PG disposal, closing the materials loop and enhancing
the circularity of this material.

Investigation of influence of additives on properties of multi-molecular organic solutions used for permeation grouting
Authors: Mackevičius Rimantas , Sližytė Danutė , Zhilkina Tatyana , Turchin Vadim
Published: December 2019

Permeation grouting for stabilization of dispersive sandy and gravely soils is in use from beginning of 19th
century and has high importance for various underpinning, tunneling, and structural strengthening works. As materials
for permeation grouting are applied not only cement mortar or silica gel in many compositions but multi-molecular
organic solutions too. From multi-molecular organic solutions for permeation grouting are in use various synthetic resins
such as acrylic, urea-formaldehyde, or other polymer resins. Urea-formaldehyde resin has right physical and mechanical
properties for applying in soil stabilization but additives can change these properties. For example, additives can increase
density, pH-rate, and gel-formation time of urea-formaldehyde resin. Additives can decrease viscosity of solutions based
on urea-formaldehyde resin. Additives can improve environmental aspects of use of multi-molecular organic solutions
for grouting of sandy soils. Long-time investigations of influence of additives on properties of multi-molecular organic
solutions used for soil stabilization give good results for optimization of composition of materials for grouting.
Initial results of local strength analysis of a fiber concrete plate by 4-point bending tests
Authors: Goidyk Oksana , Herrmann Heiko
Published: December 2019

The analysis of the post-cracking behavior of a large plate cast of fiber concrete shows a large variability due
to the fiber alignment and dispersion. Therefore, one can expect, that the bending strength and other material parameters
depend on the position in the plate. This means that the position the samples for testing are taken from may play a
significant role in assessing the mechanical properties and strength of composite materials. Often, the investigation of
fiber concrete properties have been performed by testing small size beams. The results can be influenced by the boundary
restrictions, such as wall-effect, which influences the fiber distribution. In this study the four-point bending strength of
beams cut out of a large plate was investigated, the results represent the local strength of the plate in this particular place.
The fiber orientation and distribution have been evaluated by X-ray Computed Tomography and Image Analysis
Method. The results of the experiments have shown that the position of the beam inside of a large-size plate has a strong
influence on the mechanical properties and post-cracking behavior. The analysis of the obtained outcomes proposes the
following conclusions: the beams that were located near the edges of the formwork have shown a strong, strain-hardening behavior, and the beams that were located on the way of the casting bucket (a zone of the high turbulence/perturbation/disturbance) have shown a weak, strain-softening behavior.
Experimental investigation on friction between foundation slabs and substructure
Authors: Holschemacher Klaus , Löber Philipp
Published: December 2019

For verification of structural safety (ultimate limit states – ULS) and serviceability (serviceability limit
states – SLS) of reinforced concrete structures direct and indirect actions must be considered. The main reason for
unexpected wide cracks in foundation slabs is restraint due to development and discharge of hydration heat, shrinkage
and climatic actions. The amount of restraint is dependent on friction forces between the lower side of the foundation
slab and the substructure. Friction coefficient is influenced by the properties of the sliding layer that is in many cases
provided by two layers of PE foil.
In various normative regulations and design recommendations there are proposals for mean values of friction coefficients in the context of design of foundation slabs. Because these friction coefficients strongly differ even for comparable
sliding layers an experimental investigation has been carried out aiming on better understanding of the friction behavior
between foundation slabs and substructure. The paper describes the test program and reports the investigated friction
coefficients.

compressive strength, and capillary water absorption depending on intensive mixing time. In this research microstructure, such as pore size diameters, depending on mixing time is also analysed.
INCOME INEQUALITY, GLOBALIZATION, AND COUNTRY RISK: A CROSS-COUNTRY ANALYSIS
Authors: Lee Chi-Chuan , Lee Chien-Chiang , Lien Donald
Published: December 2019

Guided by the assessments of globalization in its broader sense, this paper explores the impact of globalization in terms of a salient aspect of economic, social and political on income inequality for a more comprehensive dataset of 121 countries from 1984 to 2014. We also investigate whether the correlations between globalization and inequality vary with economic, financial, and political country risk indicators. Our empirical results reveal that globalization deteriorates income distribution, but economic and financial stability can mitigate the adverse effect. In addition, lowerincome or non-OECD countries generally have higher inequality caused by globalization. Knowledge of these relationships can help the government to formulate more specific policies aiming at improving the income distribution.

Published: December 2019

Dark-matter-only simulations predict that dark matter halos have steep, cuspy inner density profiles, while observations of dwarf galaxies find a range of inner slopes that are often much shallower. There is debate whether this discrepancy can be explained by baryonic feedback or if it may require modified dark matter models. In Paper I of this series, we obtained high-resolution integral field Hα observations for 26 dwarf galaxies with M
* = 108.1−109.7

. We derived rotation curves from our observations, which we use here to construct mass models. We model the total mass distribution as the sum of a generalized Navarro–Frenk–White (NFW) dark matter halo and the stellar and gaseous components. Our analysis of the slope of the dark matter density profile focuses on the inner 300–800 pc, chosen based on the resolution of our data and the region resolved by modern hydrodynamical simulations. The inner slope measured using ionized and molecular gas tracers is consistent, and it is additionally robust to the choice of stellar mass-to-light ratio. We find a range of dark matter profiles, including both cored and cuspy slopes, with an average of

, shallower than the NFW profile, but steeper than those typically observed for lower-mass galaxies with M
* ∼ 107.5

. Simulations that reproduce the observed slopes in those lower-mass galaxies also produce slopes that are too shallow for galaxies in our mass range. We therefore conclude that supernova feedback models do not yet provide a fully satisfactory explanation for the observed trend in dark matter slopes.

Authors: Harahap Juliandi , Rania Rashvini
Published: December 2019

BACKGROUND: Cataracts are a multifactorial systemic disease that causes opacity of the optical lens. One aetiology of cataracts is chronic hyperglycemia, usually caused by uncontrolled diabetes mellitus.
AIM: The objective of this study is to identify risk factors of cataracts and to analyse if there is a significant difference in blood glucose values between diabetic patients with cataracts and non-diabetic patients with cataracts.
METHODS: This was an analytical case-control study with a sample size of 140 patients that were obtained via consecutive sampling of medical records. This study found that age, high body mass index and hypertension were the dominant risk factors of cataracts.
RESULTS: The mean value of blood glucose levels in diabetic patients with cataracts is 195.58 ± 63.9 and 109.7 ± 26.4 in non-diabetic patients with cataracts. There was a significant difference between the blood glucose values of diabetic patients with cataracts and non-diabetic patients with cataracts (p < 0.001). The dominant risk factors of cataracts were old age, high body mass index and hypertension. The majority of hyperglycemic patients belong in the group of diabetic patients with cataracts.
CONCLUSION: Chronic hyperglycemia can increase a patient’s risk of cataracts.

Published: December 2019

Deer keds are obligatory haematophagous parasites of large homeothermic animals, particularly cervids. Two of the five known species occurring in Europe—Lipoptena cervi (Linnaeus) and L. fortisetosa Maa—are known to have a relatively wide distribution. Lipoptena fortisetosa is considered to have been introduced into Europe with sika deer from the Eastern Palaearctic and is continuously expanding its range. Little is known about the medical importance of deer keds, but they can cause hair loss in cervids and are suspected to be vectors of several diseases.

Details of the distribution of Lipoptena fortisetosa in Europe, including its northernmost record, are provided. This species has been shown to have a viable population in Southern Estonia. Furthermore, the differences from allied L. cervi are discussed, based on morphological and molecular characters.

À travers l’étude d’un dispositif de démocratie participative mis en œuvre à Boston en 1983, cet article restitue les modalités de fabrication d’un « nouveau » public de l’action publique, à savoir les « citoyen·ne·s gays et lesbiennes », et analyse les logiques qui sous-tendent ce processus de catégorisation. Si la conception du dispositif prend en compte l’hétérogénéité de la population cible, des logiques élitaires et socialement sélectives sont néanmoins à l’œuvre dans le recrutement d’« expert·e·s » fortement doté·e·s en capitaux scolaires. Afin de déconflictualiser les relations entre la communauté gaie et lesbienne et les pouvoirs publics, une approche psychologisante des rapports sociaux est promue par l’équipe du dispositif.
Résister à bas bruit aux catégorisations institutionnelles dans des dispositifs de participation à Berlin
Authors: Chevallier Thomas
Published: December 2019

Cet article porte sur trois dispositifs de participation mis en œuvre dans un même quartier de Berlin : un café des parents dans une communauté d’acteurs éducatifs, un atelier cuisine dans une association de cours d’alphabétisation, et le dispositif « Mères de quartier » employant des femmes issues de l’immigration afin de leur faire jouer un rôle de relais d’intégration. À partir d’une approche ethnographique et interactionniste, l’article cherche à déterminer les manières dont les catégorisations de « migrant·e·s », « parents » et « mères » à travers lesquelles les publics sont ciblés sont appropriées par les participantes effectives (essentiellement des femmes). Dans un premier temps, l’article revient sur les catégorisations, le contexte sociopolitique dans lequel celles-ci s’inscrivent et les objectifs d’activation et d’intégration qu’elles poursuivent. Puis il étudie les pratiques et processus par lesquels les participantes effectives, soutenues par les encadrantes, construisent une forme d’entre-soi en s’appuyant sur la résistance vis-à-vis des assignations et prescriptions qui leur sont attachées.
Le vote professionnel, entre rapport au syndicalisme et rapport au métier et à l’institution : le cas des enseignant·e·s du secteur public en France
Authors: Haute Tristan
Published: December 2019

En France, l’abstention aux élections professionnelles est élevée et en hausse, y compris pour une profession fortement engagée, mobilisée et syndiquée comme les enseignants. En éclairant ce paradoxe à partir de nouvelles données d’enquête et en s’appuyant sur les outils de la sociologie électorale, cet article montre que le vote professionnel des enseignants constitue une pratique participative conditionnée d’une part par leur rapport au syndicalisme et d’autre part par leur rapport au métier et à l’institution scolaire. Si le vote professionnel s’articule fortement avec certaines pratiques syndicales, notre analyse montre que la pratique du vote professionnel est bien plus dépendante du degré d’intégration professionnelle que l’adhésion ou l’information syndicales.
Les partis et l’Europe

Published: December 2019

Cet article s’interroge sur l’européanisation de la compétition partisane nationale. Nous revenons sur le débat concernant les effets de l'intégration européenne sur la vie nationale en examinant la politisation des enjeux européens à travers leur traitement dans les programmes électoraux. En mobilisant les données du Comparative Agendas Project, nous montrons que l’hypothèse classique de l’absorption des enjeux européens par des clivages nationaux doit être modérée. Nos trois cas – l’Allemagne, la France et le Royaume-Uni – illustrent en effet des modalités de politisation des enjeux européens assez contrastés, avec une part très variable des « enjeux constitutifs » liés à l’architecture et à la légitimité de l’UE par rapport aux enjeux d’action publique. Cette recherche exploratoire confirme donc l’importance d’une prise en compte de la substance des problèmes politisés en lien avec l’intégration européenne.
Policies with and without Politics: Committees and the Differentiated Politicization of Legislative Debates in the European Parliament
Authors: Laloux Thomas , Pennetreau Damien
Published: December 2019

Parce qu'ils permettent aux députés européens d'exprimer publiquement et de confronter leurs positions sur les législations à adopter, les débats en plénière au Parlement européen constituent des espaces importants de politisation. Cependant, étant donné le rôle central des commissions dans le processus décisionnel du PE et les différences entre elles, la politisation des débats en plénière est susceptible de varier selon les commissions qui ont préparé les dossiers législatifs. De ce point de vue, le présent article vise à comparer la politisation des débats en fonction de la commission parlementaire responsable du dossier. En pratique, nous mesurons la politisation des débats à l'aune du nombre de députés qui y participent. Les résultats confirment que la politisation des débats législatifs diffère en fonction de la commission qui est chargée de préparer les dossiers débattus. Les débats à propos des dossiers venant de commissions qui ont des processus décisionnels plus conflictuels tendent à être plus politisés. Par contre, les résultats ne permettent pas de conclure que l'importance des enjeux traitées par une commission a un effet sur la politisation des débats en plénière sur ses dossiers.
Évaluation du traitement ostéopathique pour les symptômes dus au sevrage toxicologique
Authors: Klitting Baptiste
Published: December 2019

Le centre médical Marmottan est un hôpital qui accueille des patients usagers de drogues désireux d’être suivis médicalement ou d’effectuer un sevrage. Ce sevrage s’accompagne d’un effet de manque à divers degrés, et de traitements médicamenteux entraînant eux-mêmes certains symptômes. Ces symptômes sont entre autres des constipations et des douleurs dans les membres inférieurs de type courbatures ou sensations de « jambes lourdes ». Ces patients ont ainsi été amenés à suivre des consultations d’ostéopathie, ce qui a permis d’évaluer l’efficacité des actes ostéopathiques adaptés à ces symptômes. Les différents tests statistiques ont permis de mettre en évidence une diminution de la douleur pour les membres inférieurs et une augmentation de la fréquence des selles en deux consultations. Ces tests n’ont pas permis de mettre en évidence une diminution du diamètre du côlon sigmoïde.
«Ahí van esos chulos». Militares, indisciplina y orden público en la primavera española de 1936
Authors: Álvarez Tardío Manuel
Published: December 2019

Este artículo se ocupa de uno de los aspectos ineludibles en un análisis político de los últimos meses de la Segunda República española: el papel de los militares. El objetivo fundamental es profundizar en una perspectiva de proximidad que enriquezca lo que ya sabemos sobre la preparación del golpe y sus protagonistas. La cuestión de los militares y el gobierno del Frente Popular se ha venido abordando desde el punto de vista de las tramas conspirativas, lo que podría definirse como una visión desde arriba del golpe. El artículo muestra, mediante un estudio de caso, la importancia de complementar esa visión con un enfoque desde abajo. Con ese objetivo, se han utilizado fuentes judiciales y locales que aportan una información muy significativa sobre el papel de algunos oficiales durante aquella primavera y el impacto de la violencia política y la quiebra de las jerarquías sociales tradicionales sobre la disciplina militar.
No solo el Ejército y la Milicia. Los beneficiarios de la represión económica en el ámbito de la Octava División Orgánica
Authors: Prada Rodríguez Julio
Published: December 2019

En este artículo se estudian los beneficiarios de las diferentes modalidades de represión económica en la España franquista, en particular las multas, las suscripciones patrióticas, las requisas y las incautaciones de bienes de los desafectos. Para ello se utiliza un amplio repertorio de fuentes documentales procedente de las Secciones de Estado Mayor de la Octava División Orgánica y los expedientes de responsabilidades civiles y políticas incoados por las Comisiones de Incautación de Bienes y el Tribunal Regional de Responsabilidades Políticas de A Coruña.
La combinación de la información obtenida con las bases de datos sobre la represión franquista en Galicia elaboradas por la historiografía tras dos décadas de investigación, permite obtener inferencias relevantes en cuanto a la procedencia ideológica y social de los diferentes actores implicados. Se concluye que los principales favorecidos por aquella fueron el Ejército y las Milicias, pero también un número significativo de particulares cuya variada extracción no permite generalizar la idea de amplias capas de la población unidas al régimen por unas lealtades conformadas exclusivamente por el hecho de haber resultado beneficiados por el expolio de los bienes de los enemigos de la «nueva España».
La circulación del libro entre España y el virreinato del Perú a fines del siglo XVIII
Authors: Vera Alejandro , Guillermo Muñoz (†) Juan , Hachim Luis
Published: December 2019

El presente artículo estudia la circulación del libro entre España y el virreinato peruano a finales del siglo XVIII. A partir de una revisión sistemática, efectuada en el fondo Real Aduana del Archivo General de la Nación del Perú, analiza 48 cargamentos con libros que fueron importados de Cádiz al Callao entre 1779 y 1789, con el fin de ser vendidos en Lima y, en menor medida, en otras ciudades como Santiago de Chile, Cuzco y Guayaquil. El texto está dividido en dos secciones. En la primera, revisa el marco de la historia cultural del libro y la bibliografía existente, para concluir que, sin perjuicio de sus valiosos aportes, esta se ha centrado en los siglos XVI a XVII y no ha examinado los «registros de entrada» del Callao, sino únicamente los «registros de ida» conservados en el Archivo General de Indias. En la segunda sección se presenta una primera evaluación del corpus revisado, que confronta los datos obtenidos con la información ya conocida sobre el tráfico del libro hacia el Perú. Esto permite concluir, entre otras ideas de interés, que la época estudiada se caracteriza por una secularización del material bibliográfico —en gran medida por el incremento de los libros científicos—; la coexistencia de materiales tradicionales y modernos; la plena compenetración de los impresores españoles con el mercado virreinal —que recibía sus ediciones el mismo año en el que aparecían o poco después—; y la efectiva recepción de los libros importados por parte de los habitantes del virreinato.
La Cueva de Baltzola (Dima, Bizkaia): un nuevo conjunto de arte parietal paleolítico en un yacimiento clásico
Authors: Intxaurbe Iñaki , Rivero Olivia , Salazar Sergio , Garate Diego
Published: December 2019

Este trabajo presenta el descubrimiento y posterior estudio de grafismos rojos de estilo paleolítico en la cueva de Baltzola (Dima, Bizkaia). Las labores de prospección y documentación allí desarrolladas por los arriba firmantes han identificado un modesto conjunto decorado en el que destaca un ideomorfo difícil de caracterizar. Pudiera tratarse de un signo encajable entre los “claviformes cantábricos” (conocidos en cuevas como Altamira, Tebellín o La Pasiega B y C) o “cuadriláteros con apéndice” (identificados en las de La Pasiega A o El Castillo). La rigidez de las tipologías hasta ahora planteadas para clasificar a los ideomorfos, pudiera obviar la existencia de límites muy difusos entre unos y otros. Además es un signo hasta ahora inédito en el oriente de la Cornisa Cantábrica, que permite correlacionar la cavidad de Baltzola con otras situadas en el centro-oeste cantábrico, pero cuya atribución cronológica precisa resulta difícil a falta de dataciones directas.
