Intelligent Supply Chain Information System Based on Internet of Things Technology under Asymmetric Information
Authors: Zhou Yunshan , Xu Xiangjun
Published: May 2019

The hardware and software designed in the traditional supply chain system lack cooperation in the transmission process, have low efficiency, and lead to a large amount of information distortion.In response to this problem, this paper proposes an intelligent supply chain information system based on the Internet of Things technology. The research focuses on the hardware and software of the system. The hardware part consists of the embedded processor CS89712, Flash7861 memory, Ethernet, touch screen, and LCD (Liquid Crystal Display). The software system is based on asymmetric information theory design and is divided into signal acquisition, input signal detection, interference signal processing, and power signal output. The experimental results show that it is compared with the traditional supply chain information system. The designed system seamlessly integrates the hardware and software components to achieve maximum information supply in the shortest amount of time. The power supply capacity is four times that of the traditional system, and the node coverage is high. When the number of data nodes is 120, the traditional supply chain system is basically unable to supply, but the supply accuracy of the intelligent supply chain is still as high as 48%. The research in this paper has certain guiding significance for intelligent technology development, supply chain system design, and enterprise information exchange.

Published: May 2019

Fusarium head blight (FHB), caused principally by the species belonging to the Fusarium graminearum species complex (FGSC), is an important disease in wheat, barley, and other small grain crops worldwide. Grain infected with species in the FGSC may be contaminated with trichothecene mycotoxins such as deoxynivalenol (DON) and nivalenol (NIV). In this study, we characterized the phylogenetic relationships, chemotype diversity, phenotypic characters, and aggressiveness of 150 strains in FGSC collected from eight different countries. Phylogenetic analysis based on portions of translation elongation factor 1-α (EF-1α) gene from 150 strains revealed six species in the FGSC, F. graminearum s.s, F. asiaticum, F. meridionale, F. cortaderiae, F. boothii, and F. austroamericanum. In this collection, 50% of the strains were 15-acetyldeoxynivalenol (15-ADON), 35% were 3-acetyldeoxynivalenol (3-ADON) and 15% were NIV. Evaluation of strains on moderately resistant (MR) wheat cultivar Carberry indicated that there is no significant difference among the species for FHB disease severity (DS), fusarium damaged kernel percentage (FDK%) and DON production. However, significant differences were observed among the chemotypes. Results showed significantly higher FHB DS, FDK%, DON production, growth rates, and macroconidia production for the 3-ADON strains than the 15-ADON and NIV strains. In addition, significant differences for FHB response variables were observed among the strains from different countries. Our results demonstrate that type and amount of trichothecene produced by a strain play a key role in determining the level of aggressiveness of that particular strain, regardless of the species.

Bats can host pathogenic organisms such as viruses and fungi, but little is known about the pathogenicity of their parasites. Hemoparasites are frequently recorded in Neotropical bats, particularly Litomosoides (Filarioidea: Onchocercidae), but their pathogenic effect on bats is scarcely known. In this work, Litomosoides microfilariae were identified in four (8%) out of 51 sampled frugivorous bats belonging to three different species: Artibeus aztecus, Artibeus jamaicensis, and Artibeus lituratus, which are located in Yautepec, Morelos, Mexico. Two infected animals showed weakness, tachypnoea, and ecchymosis on their wings. In these animals, histopathology revealed microfilariae in the blood vessels of the lung, liver, and spleen. Both animals presented exudative pneumonia with congestion and concomitant edema, in addition to moderate arterial hypertrophy. Parasitemia was quantified in blood samples of the infected animals (>3000 parasites/mL). Phylogenetic analysis placed the obtained sequence inside the Litomosoides genus, reaching over 98% identity to the related species. Due to the relevance of bats in ecosystems, any new record of their parasite repertoire offers noteworthy insights into our understanding of the ecology and impact of new parasite species in bats.

Published: May 2019

Nuclear–nuclear collisions at energies attainable at the large accelerators RHIC and the LHC are an ideal environment to study nuclear matter under extreme conditions of high temperature and energy density. One of the most important probes of such nuclear matter is the study of production of jets. In this article, several jet shape observables in Au+Au collisions at the center of mass energy per nucleon–nucleon pair of s N N = 200 GeV simulated in the Monte Carlo generator JEWEL are presented. Jets were reconstructed using the anti- k T algorithm and their shapes were studied as a function of the jet-resolution parameter R, transverse momentum p T and collision centrality.
NF-κB-Dependent Production of ROS and Restriction of HSV-1 Infection in U937 Monocytic Cells

Published: May 2019

Herpes simplex virus 1 (HSV-1) can infect a wide range of cell types, including cells of the adaptive and innate immunity but, normally, it completes a fully-permissive replication cycle only in epithelial or neural cells. Complex mechanisms controlling this delicate balance in immune cells and consequent restriction of HSV-1 infection in these cells have not been completely elucidated. We have recently demonstrated that the transcription factor nuclear factor kappa B (NF-κB) can act as a main permissiveness regulator of HSV-1 infection in monocytic cells, however, mediators involved in this regulation have not been identified. To better define mechanisms involved in this phenomenon and, particularly, the possible involvement of ROS, wild type U937 cells or U937 cells stably transfected with a dominant-negative (DN) IκB-mutant and selenium-containing compounds, as anti-oxidants, were utilized. The main results can be summarized as follows. HSV-1 infection induces an immediate ROS production in U937 monocytic cells that can efficiently activate NF-κB but not in DN-IκB-mutant cells. Treatment with selenium-containing antioxidants efficiently inhibited HSV-1-induced ROS generation while producing increased levels of HSV-1 replication and a reduction of HSV-1-induced NF-κB activation in U937 monocytic cells. Our results suggest a scenario in which an efficient NF-κB-dependent ROS production in response to infection could contribute in limiting HSV-1 replication in monocytes/macrophages, thus avoiding possible irreparable damage to the innate immune system of the host during HSV-1 infection.
The Antigenic Topology of Norovirus as Defined by B and T Cell Epitope Mapping: Implications for Universal Vaccines and Therapeutics
Authors: van Loben Sels Jessica M. , Green Kim Y.
Published: May 2019

Human norovirus (HuNoV) is the leading cause of acute nonbacterial gastroenteritis. Vaccine design has been confounded by the antigenic diversity of these viruses and a limited understanding of protective immunity. We reviewed 77 articles published since 1988 describing the isolation, function, and mapping of 307 unique monoclonal antibodies directed against B cell epitopes of human and murine noroviruses representing diverse Genogroups (G). Of these antibodies, 91, 153, 21, and 42 were reported as GI-specific, GII-specific, MNV GV-specific, and G cross-reactive, respectively. Our goal was to reconstruct the antigenic topology of noroviruses in relationship to mapped epitopes with potential for therapeutic use or inclusion in universal vaccines. Furthermore, we reviewed seven published studies of norovirus T cell epitopes that identified 18 unique peptide sequences with CD4- or CD8-stimulating activity. Both the protruding (P) and shell (S) domains of the major capsid protein VP1 contained B and T cell epitopes, with the majority of neutralizing and HBGA-blocking B cell epitopes mapping in or proximal to the surface-exposed P2 region of the P domain. The majority of broadly reactive B and T cell epitopes mapped to the S and P1 arm of the P domain. Taken together, this atlas of mapped B and T cell epitopes offers insight into the promises and challenges of designing universal vaccines and immunotherapy for the noroviruses.

The Limitations of Reward Effects on Saccade Latencies: An Exploration of Task-Specificity and Strength
Authors: Dunne Stephen , Ellison Amanda , Smith Daniel T.
Published: May 2019

Saccadic eye movements are simple, visually guided actions. Operant conditioning of specific saccade directions can reduce the latency of eye movements in the conditioned direction. However, it is not clear to what extent this learning transfers from the conditioned task to novel tasks. The purpose of this study was to investigate whether the effects of operant conditioning of prosaccades to specific spatial locations would transfer to more complex oculomotor behaviours, specifically, prosaccades made in the presence of a distractor (Experiment 1) and antisaccades (Experiment 2). In part 1 of each experiment, participants were rewarded for making a saccade to one hemifield. In both experiments, the reward produced a significant facilitation of saccadic latency for prosaccades directed to the rewarded hemifield. In part 2, rewards were withdrawn, and the participant made a prosaccade to targets that were accompanied by a contralateral distractor (Experiment 1) or an antisaccade (Experiment 2). There were no hemifield-specific effects of the reward on saccade latency on the remote distractor effect or antisaccades, although the reward was associated with an overall slowing of saccade latency in Experiment 1. These data indicate that operant conditioning of saccadic eye movements does not transfer to similar but untrained tasks. We conclude that rewarding specific spatial locations is unlikely to induce long-term, systemic changes to the human oculomotor system.

Published: May 2019

The study investigated the effect of storage conditions on the stability of electrolyzed seawater (ESW)’s physicochemical properties (pH, oxidation-reduction potential (ORP), and free chlorine (FC) concentration), and bactericidal efficiency on the fecal coliform Escherichia coli for 30 days. Preliminary experiments were conducted to determine the optimal current and electrolysis time. Two batches of 2750 mL filtered seawater were electrolyzed using 50 mm × 192 mm platinum–titanium mesh electrodes at a current of 1.5 A for 20 min. One hundred milliliters of electrolyzed solution was transferred into each amber glass and high-density polyethylene (HDPE) bottles. The bottles were stored in a dark area at ambient temperature. The results showed an increase in pH and a decrease in ORP and FC concentration through time. Hypochlorous acid remained as the dominant component since the pH levels of the solutions remained below 7.5. FC decay was investigated using Chick’s Law. It was determined that the decay in HDPE bottles (k = −0.066 day−1) was faster compared to amber glass bottles (k = −0.046 day−1). Nonetheless, HDPE bottles could still be used as an alternative container for 30 days only due to observed instability beyond 30 days. ESW remained effective since no surviving population of E. coli was observed throughout the experimentation.
Coping with Extreme Events: Effect of Different Reservoir Operation Strategies on Flood Inundation Maps
Authors: Ridolfi Elena , Di Francesco Silvia , Pandolfo Claudia , Berni Nicola , Biscarini Chiara , Manciola Piergiorgio
Published: May 2019

The need of addressing “residual flood risk” associated with structural protection measures, such as levee systems and flood-control reservoirs, has fostered actions aimed at increasing flood risk awareness. Structural measures have lowered risk perception by inducing a false sense of safety. As a result, these structures contribute to an underestimation of the “residual risk”. We analyze the effect of different reservoir operations, such as coping with drought versus coping with flood events, on flood inundation patterns. First, a hydrological model simulates different scenarios, which represent the dam regulation strategies. Each regulation strategy is the combination of an opening of the outlet gate and of the initial water level in the reservoir. Second, the corresponding outputs of the dam in terms of maximum discharge values are estimated. Then, in turn, each output of the dam is used as an upstream boundary condition of a hydraulic model used to simulate the flood propagation and the inundation processes in the river reach. The hydraulic model is thus used to determine the effect, in terms of inundated areas, of each dam regulation scenario. Finally, the ensemble of all flood inundation maps is built to define the areas more prone to be flooded. The test site is the Casanuova dam (Umbria, central Italy) which aims at: (i) mitigating floods occurring at the Chiascio River, one of the main tributaries of Tiber River, while (ii) providing water supply for irrigation. Because of these two competitive interests, the understanding of different scenarios generated by the dam operations offers an unique support to flood mitigation strategies. Results can lead to draw interesting remarks for a wide number of case studies.
Simulation of Long-Term Soil Hydrological Conditions at Three Agricultural Experimental Field Plots Compared with Measurements

Published: May 2019

Soil hydrological conditions influence crop growth and groundwater recharge and, thus, precise knowledge of such conditions at field scale is important for the investigation of agricultural systems. In our study, we analyzed soil hydrological conditions at three agricultural experimental field plots with sandy soils and different crop rotations using a 22-year period from 1993 to 2014 with daily volumetric soil water contents measured by the Time Domain Reflectometry with Intelligent MicroElements (TRIME)-method and pressure heads determined by automatic recording tensiometers. These measured data were compared with soil water contents and pressure heads simulated by a process-based agroecosystem model. Within this 22-year period, time spans with a better model performance and periods with a lower goodness of fit between simulations and observations were observed. The lower goodness of fit in the summer periods was attributed to inadequate calculations of root water uptake. Measurement errors of the TRIME-probes and differences between soil water contents measured by TRIME and pressure heads observed by tensiometers due to different measurement volumes, precision and measuring principles were identified as further reasons for mismatches between simulated and measured model outputs.
Hydrological Simulation for Karst Mountain Areas: A Case Study of Central Guizhou Province

Published: May 2019

A groundwater model is needed to describe the complex groundwater confluence process of the groundwater system in karst areas. This is because surface water flows through dolines, grikes, and by other means and is directly exchanged with the groundwater. In this study, using the Xin’anjiang model, the conversion of surface water into groundwater and the influence of multiple series-parallel underground reservoirs on groundwater confluence through the generalization of dolines in karst areas were simulated. The water cycle process in the Sancha River Basin was simulated with measured data using multiobjective particle swarm optimization. Then, model parameters were validated with measured runoff data and compared with simulation results obtained using the traditional Xin’anjiang model based on its optimal parameters. The results showed that the determination coefficients of all hydrological stations over the study period were >0.76, and the Nash efficiency coefficient was >0.76, which were better than those for the improved Xin’anjiang model. Next, the simulation accuracy of the flood period in the karst area was analyzed. The model achieved a high fitting rate for the main flood peaks in a year, and the passing rate for the worst hydrological stations was 53%. Finally, the influence of karst development on the runoff was examined. The results indicate that different karst development stages and the heterogeneity of the karst in the basin have different effects on runoff.
Participatory Water Governance and Organisational Change: Implementing the Water Framework Directive in England and Wales
Authors: Fritsch Oliver
Published: May 2019

Public participation is central to the IWRM discourse and often associated with claims of improved environmental policy outputs and their implementation. Whilst the involvement of nonstate actors in environmental decision-making has attracted scholarly attention from various angles, our knowledge is scant as to the forces that drive organisational reform towards participatory governance. This article sets out to contribute to this largely neglected research area and explores conditions under which policy-makers would be willing to attend towards more participative water governance. Its ambition is twofold: first, to explore the conditions under which public officials attempt to institutionalise more participatory modes of water governance. To this end, I analyse the implementation of the Directive’s active involvement provision in England and Wales. For many decades, water management in England and Wales had a reputation for being a technocratic exercise. In the past 15 years, however, the Environment Agency has made considerable efforts to lay the foundation for enhanced stakeholder participation. Second, with reference to the case of England and Wales, this study contributes to understanding the difficulties that reformers may meet when it comes to building support within an organisation and to implementing reforms towards participatory governance.
PROBLEM ASPECTS OF FORENSIC EXAMINATION ON STATE SECRETS’ ISSUIS IN CRIMINAL PROCEEDING
Authors: Tyshchenko Ye.
Published: May 2019

Article 518 of the Code of Criminal Procedure of Ukraine for the first time regulated the production of forensic examination regarding the legality of attributing information in the field of defense, economics, science and technology, foreign relations, state security and law enforcement to state secrets, changing the secrecy of this information and its declassification damage caused to the national security of Ukraine in the event of the disclosure of classified information or the loss of material carriers of such information. This definition is cumbersome, that is why it is advisable to call the expertise at issue broader in content and more laconic in form – “in matters of state secrets”.

The appointment, support and conduct of forensic examinations on this issue is accompanied by lengthy and still not completed scientific discussions and related practical problems, which include subjects which are able to conduct examinations on state secrets, and the methodology for conducting them.

Thus, the disposition of Part 1 of Art. 518 Code of Criminal Procedure of Ukraine regarding the subject of the examination on state secrets do not correspond to the content of other applicable laws and regulations.

Also, no certified and registered by the established procedure methodology for conducting forensic examination on state secrets’ issues has been established.

In order to comply with the rule of law and legality as basic criminal proceedings according to Art. Art. 7, 8, 9, 22 Code of Criminal Procedure of Ukraine:

– it requires forming by authorized order the type of forensics as a state secret forensic and a type of relevant expert specialty;

– it is advisable to expand the circle of subjects of expertise on state secrets’ issues at the expense of other specialists who are knowledgeable in matters of state secrets. They can be members of expert commissions under state secrecy experts, if at the same time complying with the set of normatively defined requirements for judicial experts who are not employees of state specialized agencies conducting forensic examinations. These requirements must also be met by state secrecy experts. In the future, a crucial step could be to consider the assignment of the functions of judicial experts on state secrets’ issues to the Security Service of Ukraine staff, which is entrusted with Article 2 of the Law of Ukraine “On the Security Service of Ukraine” to ensure the protection of state secrets and which is a specially authorized state body in the field of ensuring the protection of state secrets in accordance with Part 5 of Article 5 of the Law Of Ukraine “On State Secrets”;

– authorized state bodies are obliged to solve the problem of developing, certifying and state registration of a methodology for conducting a forensic examination on state secret issues. Key words: state secret, forensic examination.

The need to use information in the investigation of any of the information, regardless of their subordination and direct appointment follows logically from the fact that objects of any variety act counts material world objects and events. Notable among these are the people who in the course of their life activities are accounting objects in different systems. They are recorded by place of birth, education, residence, work as users various tools (weapons, vehicles, etc.) and so on. Some of them are becoming of the objects forensic information systems. And in the case of their involvement in criminal activities there is a need retrospective analysis of previous life, belonging to a particular activity, events, etc. In the context of accounting information in the fight against organized crime V. P. Bahin said: “In the specialized accounting of the MIA and SBU there are many different institutions, which records a variety of acts and actions of citizens. Indeed, the results of analysis of crimes practice investigation indicate that the information that may be useful in the investigation process can be found in any information systems regardless of the underlying purpose and subordination”.

The article deals with the basic information and reference systems of other ministries and departments as a part of information and reference ground for robbery investigation.

Synthesis of binders and materials characterized by polycomponent composition, generally, is associated with necessity of improvement of certain properties or formation of principally new characteristics in this materials. In this paper hybrid geopolymers based on fly ash were synthesized using different types of mineral modifiers such as Portland cement (PC), kaolin, metakaolin (MK). It was defined, that values of compressive strength, water resistance and water absorption for PC-containing geopolymers are better than free of modifier geopolymer as well as for kaolin- and MK-containing geopolymers. It was determined that high-temperature treatment (at 600 °C) provides with reinforcing and improvement of water resistance of kaolin- and MK-containing hybrid geopolymers. PC-containing hybrid geopolymers demonstrated a sharp reducing in compressive strength and average density. For this system, in temperature range of 400–600 °C a dramatic growth of compressive strength is observed when average density grows or a constant. Thus, PC-containing hybrid geopolymers are not thermal resistant, that confirmed by degradation of its performance characteristics under high temperature effect.

Transit-oriented development (TOD) is a strategy of urban planning that aims to maximize the efficient use of the territory near the transport hub and facilitate the transition to sustainable development of cities and regions. The research is aimed at studying the emergence and development of TOD as part of New Urbanism concept in the history of urban planning and the most important characteristics of TOD. The typology of transit-oriented development plays an important role in urban planning. Its application simplifies the management of infrastructure projects by applying standards in planning and development, as well as ensuring consistency in various areas. In addition, support for planners, administrative staff and developers is of great importance for development, depending on such characteristics as population density, mixing of functions, ways of movement of citizens, activities, etc. The introduction of typology makes it possible to identify the territory and its users with already existing design solutions or experience for more thorough spatial planning.

Rapid Magnetic 3D Printing of Cellular Structures with MCF-7 Cell Inks
Authors: Mishriki S. , Abdel Fattah A. R. , Kammann T. , Sahu R. P. , Geng F. , Puri I. K.
Published: May 2019

A contactless label-free method using a diamagnetophoretic ink to rapidly print three-dimensional (3D) scaffold-free multicellular structures is described. The inks consist of MCF-7 cells that are suspended in a culture medium to which a paramagnetic salt, diethylenetriaminepentaacetic acid gadolinium (III) dihydrogen salt hydrate (Gd-DTPA), is added. When a magnetic field is applied, the host fluid containing the paramagnetic salt is attracted towards regions of high magnetic field gradient, displacing the ink towards regions with a low gradient. Using this method, 3D structures are printed on ultra-low attachment (ULA) surfaces. On a tissue culture treated (TCT) surface, a 3D printed spheroid coexists with a two-dimensional (2D) cell monolayer, where the composite is termed as a 2.5D structure. The 3D structures can be magnetically printed within 6 hours in a medium containing 25 mM Gd-DTPA. The influence of the paramagnetic salt on MCF-7 cell viability, cell morphology, and ability of cells to adhere to each other to stabilize the printed structures on both ULA and TCT surfaces is investigated. Gene expressions of hypoxia-inducible factor 1-alpha (

HIF1
α

) and vascular endothelial growth factor (
VEGF
) allow comparison of the relative stresses for the printed 3D and 2.5D cell geometries with those for 3D spheroids formed without magnetic assistance. This magnetic printing method can be potentially scaled to a higher throughput to rapidly print cells into 3D heterogeneous cell structures with variable geometries with repeatable dimensions for applications such as tissue engineering and tumour formation for drug discovery.
La cosmovisión indígena Tzotzil y Tzeltal a través de la relación salud- enfermedad en el contexto de la medicina tradicional indígena
Authors: López Hernández José R. , Teodoro Méndez José M.
Published: May 2019

Los Tzotziles y Tzeltales son dos grupos indígenas que forman parte de la antigua cultura maya, y que en la actualidad siguen conservando sus costumbres y tradiciones, las que dan sustento a su cultura e identidad. Estos grupos étnicos habitan la zona denominada Altos de Chiapas, una zona mayoritariamente indígena y de difícil acceso por su ubicación geográfica. Los Tzotziles y Tzeltales aún conservan sus ancestrales prácticas terapéuticas en lo que a medicina tradicional se refiere y está conformada por una visión del mundo o cosmovisión ajena a la cultura occidental. La medicina tradicional indígena Tzotzil y Tzeltal perdura y se sigue practicando por los médicos tradicionales y la población en general. Fundamentalmente es un sistema de origen prehispánico que tiene como eje rector su cosmovisión y descansa sobre bases mágicas y religiosas. La medicina tradicional se ha enriquecido con los conocimientos traídos por los españoles y la raza africana; en otras palabras se trata de un sincretismo médico además, ha cumplido un papel fundamental en la preservación de la salud para muchas generaciones.

Asumir que los nuevos estudios sobre el movimiento indígena en México, implican la necesidad de articular las dimensiones políticas y culturales de determinados grupos sociales, también implica reformular la manera en que se aborda el estudio de los mismos. En este estudio se plantea la necesidad de combinar las dimensiones políticas (estructura de poder local) y culturales (redefinición de identidades étnicas), para de ahí examinar las implicaciones que dicha relación tiene en el surgimiento de nuevos movimientos indígenas y la emergencia de autonomías indígenas de facto. Para los propósitos de este estudio, se plantearon las preguntas de investigación a partir de un referente determinado: una comunidad de Los Altos de Chiapas. Dicha comunidad proporcionó los elementos reales para discutir en torno a investigaciones concretas: el nuevo movimiento indígena en Chiapas y la autonomía indígena.
Derechos humanos, autonomía y poder local indígena en México (sus perspectivas ante la globalización)
Authors: Gómez González Gerardo , Urbalejo Guerra Carlos
Published: May 2019

En la era de la globalización, el tema de los derechos humanos auspiciados por las fuerzas políticas democráticas, organizaciones de la sociedad, instituciones públicas nacionales e internacionales y por grupos involucrados en todo el mundo, ha cobrado cada vez mayor importancia en el ámbito de las relaciones sociales locales, regionales, nacionales y mundiales. El planteamiento de los derechos humanos surgidos principalmente de las luchas libertarias de los pueblos del mundo, se enmarcan en el contexto social, económico, político y cultural de lo que los grupos dominantes de la sociedad occidental con todo y sus desequilibrios y contradicciones acepta. En ese marco se ubica la discusión sobre la situación y perspectiva de la autonomía indígena y poder local como manifestaciones de los derechos de los pueblos indios en México.

En México nos encontramos ante una disyuntiva de gran calado que afecta el proceso de toma de decisiones de las personas, ya que vivimos una sociedad de la información replegados en una cultura del secreto. Esto se refleja en todas y cada una de nuestras actividades cotidianas y provoca que el proceso de obtención de información sea obstaculizado por múltiples factores. La profesión periodística no se escapa a este contexto, pero encuentra en el ejercicio conciente y adecuado del Derecho de Acceso a la Información Pública un gran antídoto para enfrentar la cultura de la secrecía y el ocultamiento de la información que como un espejo se refleja desde el Servicio Público y que permea a toda la sociedad. Es por ello que los sujetos profesionales de la información ahora pueden ejercer su actividad en base a datos confiables y accesibles, impregnando a sus trabajos con un gran sentido de ética, responsabilidad y confianza, apartados que son un imperativo categórico en cualquier sociedad contemporánea.
Corrupción y derecho acceso a la información
Authors: Robles Hernández José Guadalupe
Published: May 2019

Uno de los objetivos esenciales del Derecho de acceso a la Información, es la transparencia en la información que generan los gobiernos y con ello evitar o inhibir los actos de corrupción. La corrupción proveniente del poder público genera problemas inimaginables para las sociedades de todo el mundo. Por lo que hace a la función pública, el fenómeno de la corrupción, tiene que ver con la utilización del poder o la autoridad para una finalidad distinta a la legítima, en busca de una ventaja personal, degradando la función para la que fue electo o nombrado por el afán de conseguir algo en beneficio propio.
La importancia de incluir perspectivas culturales y sociales en los procesos de desarrollo rural, como premisas para revalorar el saber tradicional
Authors: Noriero Escalante Lucio
Published: May 2019

El presente es resultado de un primer acercamiento al estudio de los conceptos de habitus y capital cultural de la vasta obra del sociólogo de la cultura Pierre Bourdieu. Consideramos que una aportación sobre estos conceptos desde una perspectiva social y cultural implican lo que se entiende por saber tradicional, hasta cuestionarse sobre cuáles son las formas en que está desapareciendo o modificándose ante la vertiginosidad de los avances científicos y tecnológicos en la agricultura. Estos cambios tienen fuertes repercusiones en las formas de concebir la producción y reproducción de la vida cotidiana de los sujetos que portan el saber tradicional y el conocimiento vigente o moderno. Situación por la cual somos partidarios de revalorar el saber tradicional ya que tiene que ver con el patrimonio cultural nacional. Finalmente, hacemos mención en que la producción basada en un enfoque agroecológico, aglutina un cúmulo de prácticas tradicionales de producción sustentadas en el uso racional de los recursos naturales, que permiten una nueva alternativa de producción basada en el respeto, cuidado y preservación entre la naturaleza y el hombre

The increased utilization of one-dimensional (1D) TiO2 and titanate nanowires (TNWs) in various applications was the motivation behind studying their stability in this work, given that stability greatly influences both the success of the application and the environmental impact. Due to their high abundance in aqueous environments and their rich technological applicability, surfactants are among the most interesting compounds used for tailoring the stability.

The aim of this paper is to determine the influence of surfactant molecular structure on TNW stability/aggregation behavior in water and aqueous NaBr solution by dynamic and electrophoretic light scattering. To accomplish this, two structurally different quaternary ammonium surfactants (monomeric DTAB and the corresponding dimeric 12-2-12) at monomer and micellar concentrations were used to investigate TNW stability in water and NaBr. It was shown that TNWs are relatively stable in Milli-Q water. However, the addition of NaBr induces aggregation, especially as the TNW mass concentration increases. DTAB and 12-2-12 adsorb on TNW surfaces as a result of the superposition of favorable electrostatic and hydrophobic interactions. As expected, the interaction of TNWs with 12-2-12 was stronger than with DTAB, due to the presence of two positively charged head groups and two hydrophobic tails. As a consequence of the higher adsorption of 12-2-12, TNWs remained stable in both media, while DTAB showed an opposite behavior.

In order to gain more insight into changes in the surface properties after surfactant adsorption on the TNW surface, a surface complexation model was employed. With this first attempt to quantify the contribution of the surfactant structure on the adsorption equilibrium according to the observed differences in the intrinsic log K values, it was shown that 12-2-12 interacts more strongly with TNWs than DTAB. The modelling results enable a better understanding of the interaction between TNWs and surfactants as well as the prediction of the conditions that can promote stabilization or aggregation.
RECREATION CAPACITY OF UKRAINE’S REGIONS, STRATEGIC GOALS OF ITS USAGE AND BUILDING

Published: May 2019

Purpose – to reveal the scientific approach to the regional policy in the field of research, use and increase the
recreational potential of the regions of Ukraine, creating an effective mechanism for the development of the recreational
system of the region due to an in-depth study of the recreational system potential, the quality of the recreational environment
and highlighting its special structure. As a sub-goal of the study was determined the identification of factors
affecting the competitiveness of the recreational system of the regions, which will make it possible to clarify the directions
of activities to increase the competitiveness of the tourism and recreation sector of the economy of Ukraine.
Findings – the paper proposes the mechanism of well-balanced mutual development of humanʼs health and recreational
system management.
Research limitations – the study addresses the problem of using recreational potential in such a way that, as a result of
its use, the least damage is inflicted on the territory and on the population. To determine the direction of development
were identified as “sore spots” groups of the recreational system. To solve this problem has been proposed a mechanism
for the balanced development of the recreational system, which will allow: 1) to maintain and develop the existing
recreational potential; 2) to increase the share of regional profits from the use of recreational potential.
Methodology – the methodology and research tools are based on the methods of theoretical generalization, refinement
of the conceptual apparatus, logical-structural modelling, scientific argumentation, and comparative analysis.
Practical implications – the practical significance lies in the fact that the article reveals the problematic issues of recreation
in Ukraine and suggests a mechanism for the management and sustainable development of the countryʼs recreational
potential. The use of the proposed mechanism will lead to an increase in the incomes of the regions from the
exploitation of the recreational potential and will create the conditions for the preservation of the recreational systems
themselves.
Originality/Value – the article value lies in the fact that it proposes a mechanism for the balanced development of the
recreational system and the person in it; carried out the allocation of recreational management in a special function of
the recreational system. The relationship between the development strategies of the recreational system and the assessment
of the recreational competitiveness of the region is shown.
On the systemic risk and optimality in non-homogenous innovation clusters
Authors: Gudelytė Laura
Published: May 2019

Purpose – to analyse the concept of systemic risk of innovation cluster and show its impact on the optimality of cluster performance as well as to cluster structure. Research methodology – general overview of research papers and documents presenting concepts and methodologies of evaluation of systemic risk and performance of networked structures as interbank markets and business clusters with regard to asymmetric information, applied research. Findings – determination of systemic risk in a networked structure that appears together with synergistic effect as a result of collaboration in a networked structure. The clique-based structure appears to be more favourable for innovation cluster performance due to optimal sharing of information and systemic risk. The interpretation of the model of evaluation of systemic risk can be at least twofold: core-periphery, business entities-R&D institutions, etc. Research limitations – lack of empirical data that cannot be used to implement empirical research on a problem of systemic risk and its modelling. Practical implications – the conceptual model of evaluation of systemic risk should be useful for understanding and further treatment of measuring risk in a case of innovation management. Originality/Value – in this paper, the model of evaluation of systemic risk in innovation cluster and its interpretations are provided. The systemic risk is treated as a generalized risk impacting directly or non-directly the performance of an innovation cluster.
An effect of symbols on consumer behaviour: the theoretical insights
Authors: Kriaučiūnaitė-Lazauskienė Gintarė , Žitkienė Rima
Published: May 2019

Purpose – this article aims to analyse and integrate the limitations of consumer’s decision-making and difficulties for symbolic consumption in relation to symbolic branding. It highlights the symbolic impact to goods, which influenced by advertising and 21st century consumer’s behaviour propagates hedonistic values.

Research methodology – the analysis of theoretical scientific literature, comparative study of conceptions.

Findings – support the idea that consumers may modify their principles about the symbolic brand depending on both their self-brand relation as well as the effect of social (both live and virtual) influence.

Research limitations – it is necessary to acknowledge that the current research is limited by broad scope consumer behaviour theories and methods (we in passing analysed empirical proves).

Practical implications – authors suggest that the emergence of brand subculture on consumer behaviour gives the possibility of adjusting specific marketing strategies and presents the shortcomings of current research by pointing out the trends for future empirical studies.

Originality/Value – It also highlights that the consumers’ search of symbolism and meaning in brands correlated with their consumer buying decision models, and we claim it could be related to utility theory. The main aim of this article is to analyse the field of symbols in advertising – in terms of their impact on the consumption process.
