Abstract: The given study focuses on the media influence on the worldview representation determined by the audience-induced changes in the semantic field of a concept. The aim of our research is to examine the media’s effect on the core of the semantic field regarding the concept of conflict and single out the methods employed by a journalist to alter the semantic field of concepts and influence the audience’s worldview. Lev Vygotsky’s cultural-historical theory, Marshall McLuhan’s media theory, and Lasswell’s theoretical foundations on the potentiality of media to influence the audience’s preferences are theoretical foundations for researching in this area. I conducted a four-stage study to define the way media content affects change the concept meaning by analysing the multidimensional concept «conflict» as an example. I exploited free listing methods, which were refined to accomplish my goal, data collection, and analysis methods as diagnostic instruments and conducted the survey among 88 students of the State University of Telecommunication (Kyiv, Ukraine). The experimental studies showed that even after a short period of intense media impact, a tested subject admitted the significant change in his point of view on the current events. The obtained results give grounds for further quantitative research to scrutinize the media impact on the audience’s worldview. Keywords: mass media influence; semantic field; conflict, alter the concept’s meaning; audience’s worldview

Prevention practices and the factors that influence them are essential for controlling the spread of dengue hemorrhagic fever (DHF) and effective strategic planning. This study aimed to determine the factors associated with the practice of preventing dengue fever in communities in endemic areas of Kubu Raya Regency, West Kalimantan Province, Indonesia. This study was an observational study with a cross-sectional design. The research sample was 379 households in endemic areas using a questionnaire. Collecting data was using a questionnaire with interviews. Bivariate analysis employed Chi-square test, multivariate analysis using logistic regression. Most of the respondents practiced fewer prevention; variables related to dengue fever prevention practices were income, education, knowledge about dengue prevention and health education (mass media). Regression analysis showed that the variables of education, knowledge about dengue prevention, and mass media education were related to the practice of preventing dengue fever. This study indicated that in preventing dengue fever, strategies must be developed to cultivate prevention practices and increase prevention campaigns using mass media and focus on areas with low education and knowledge in dengue prevention.

Full textAbstract:
Global construction industry has a huge influence on world primary energy consumption, spending, and greenhouse gas (GHGs) emissions. To better understand these factors for mass timber construction, this work quantified the life cycle environmental and economic performances of a high-rise mass timber building in U.S. Pacific Northwest region through the use of life-cycle assessment (LCA) and life-cycle cost analysis (LCCA). Using the TRACI impact category method, the cradle-to-grave LCA results showed better environmental performances for the mass timber building relative to conventional concrete building, with 3153 kg CO2-eq per m2 floor area compared to 3203 CO2-eq per m2 floor area, respectively. Over 90% of GHGs emissions occur at the operational stage with a 60-year study period. The end-of-life recycling of mass timber could provide carbon offset of 364 kg CO2-eq per m2 floor that lowers the GHG emissions of the mass timber building to a total 12% lower GHGs emissions than concrete building. The LCCA results showed that mass timber building had total life cycle cost of $3976 per m2 floor area that was 9.6% higher than concrete building, driven mainly by upfront construction costs related to the mass timber material. Uncertainty analysis of mass timber product pricing provided a pathway for builders to make mass timber buildings cost competitive. The integration of LCA and LCCA on mass timber building study can contribute more information to the decision makers such as building developers and policymakers.

Full textAbstract:
The object of the study is the official position of the authorities regarding the information security of the country and the official view of what role the mass media should play in this complex system. The authors pay special attention to recent changes in this area and the analysis of what measures have been taken by the state to regulate the issue of information security. Particular attention is focused on regulatory legal acts, which are legislative initiatives of strategic planning in the field of ensuring the national security of the Russian Federation. When working on the article, the authors emphasized the use of sociological, systemic and institutional research methods. The main conclusion of the studied problem is the awareness of the understanding that the mass media have a strong influence on public consciousness. In this case, it is important to understand who exactly uses the media as a tool of manipulation, since an adequate analysis of these processes will ensure national and information security. In particular, the author substantiates the special role of the institute of television as the main means of social control through the appropriate representation and interpretation of social reality.

Full textAbstract:
In the work, the study of six different nutrient medium compositions’ influence on the growth and development of a healthy Solnechny potato variety in the growing process in laboratory conditions in vitro was carried out. The influence of different nutrient medium compositions on plant height, number of leaves/internodes, plant weight and total leaf surface area was studied. It was revealed that nutrient media with BAP addition cause a decrease in all of the above indicators. In addition, nutrient media with this growth regulator lead to the appearance of microtubers on the plants. It has been shown that the inclusion of GA and IAA growth regulators in nutrient media leads to a slight increase in the number of internodes. An increase in the total leaf surface area was noted in the above options. It should be noted that the nutrient medium options with the addition of GA and IAA led to a decrease in the mass and length of the root system of Solnechnyi variety potato plants.

Full textAbstract:
The purpose of this study was to determine the effect of political awareness, political socialization and mass media on the political participation of the people of Jambi Province in the regional head election. Political participation is a form of community involvement in exercising their political rights in general elections both at the national and regional levels. The embodiment of political rights will affect every decision-making related to the interests of the community. This study uses a quantitative approach that uses statistical techniques with PLS model analysis techniques. The study was conducted on the people of Jambi City as many as 100 people were selected based on area sampling techniques. The research findings explain that the mass media has no direct effect on political participation. Political participation is directly influenced by the variables of Political Awareness and Political Socialization. Therefore, it is suggested that the use of mass media in the post-conflict local election in Jambi Province needs to be improved, especially information related to the political rights of the community. The tendency that occurs in the community is more interested in obtaining information related to entertainment because people are still accustomed to listening culture rather than reading culture.

Full textAbstract:
In conventional agriculture, extension officers are regarded as change agents. They intervene to bring about change through influencing innovation, technology transfer and decision-making process in order to help improve the lives of the farmers and their families. Farmers in 21st century have opportunity of receiving the majority of information about agriculture through mass media outlets as a result technology advancement.
A case study design was employed design utilizing mixed research approach focusing on Magu district as study area. The study used both primary and secondary data. The primary data were collected using purposive sampling from a sample of 148 farmers whereas the secondary data were collected from Magu District’s agriculture, irrigation and cooperative office. The data collection tools included questionnaire, focused group discussion and semi-structured interview methods. The aim of this study was to investigate how mass media is serving both extension officers and farmers to enhance agriculture knowledge and technology adaptation in the wake of few extension officers.
We found extension officer to farmer ratio to be 1:1172 and 1:500 for crop and livestock farmer respectively. This ratio falls short from World Bank recommended standard ratio of 1:200-500 as well as below the Tanzania ministry of agriculture’s standard of two extension officers per village. The rapid development of social media platforms gives the specialty crop industry the ability to speak directly to the public, informing consumers about food production and encouraging them to become agriculture advocates.
The impact of mass media among the farmers in enhancing productivity was moderate. This was easily analyzed by examining the theme content in mass media in the country and frequency of media usage by both farmers and extension officers. Amongst various mass media radio and television channels emerged as the most used, most dominant, relevant, low-cost medium and user friendly for farmer-to-farmer-extension and to expose rural communities to new agricultural technologies and ideas. Social media is the most recent form of digital communication and on a global scale and already this study reveal farmers particularly that farmer with high level of education and high-income level using social media for agriculture.

Full textAbstract:
AbstractRecent research and debates regarding the origin and spread of Olmec iconography during the Early Formative have centered on provenance and stylistic analyses of carved and incised pottery. Studies by instrumental neutron activation analysis (INAA) have indicated that Gulf Coast-style carved-incised pots were exported extensively from the area of the first Olmec capital, San Lorenzo, to several other regions of Mesoamerica. More recently, excavations at the Pacific Coast site of Cantón Corralito have shown that carved-incised pottery and other Olmec-style artifacts dominate strata contemporary with Early Olmec, suggesting the site may represent a settlement enclave of Gulf Olmec peoples. In this study we provide additional evidence of exchange between the Gulf Olmec and the Pacific Coast region by using laser ablation time-of-flight inductively coupled plasma mass spectrometry (LA-TOF-ICP-MS) to characterize hematite-based paints on Olmec-style pottery from Cantón Corralito, and to compare these paints to raw hematite recovered from Cantón Corralito and San Lorenzo. When examined in combination with sherd provenance data, the LA-TOF-ICP-MS data demonstrate that Olmec vessels were decorated in the San Lorenzo region before being exported to the Pacific Coast, and that Gulf Coast hematite was exported to Cantón Corralito, where it was used to enhance Olmec-style symbolism on locally produced vessels.

On November 13, 1945, Honolulu residents awoke to news of a mass riot the previous evening by over one thousand sailors in the Damon Tract area in Honolulu. Although it was one of the largest postwar military uprisings on American soil, the riot itself has not been carefully examined in the historical record due other events and interests locally and nationally, as the media continued to operate within a highly militarized state. Remembering and understanding the Damon Tract riot became secondary to America’s Cold War interests in the Pacific, the growth of tourism in the Islands, and efforts to garner statehood for Hawai‘i that depended on unifying these historically contentious identities at the expense of acknowledging conflict that existed in the past.

Abstract. In this study we consider contrasting continental (Orulgan, Suntar-Khayata and Chersky ranges located in the Pole of Cold area at the contact of Atlantic and Pacific influences) and maritime (Kamchatka under the Pacific influence) Russian glacier systems. Our purpose is to present a simple method for the projection of change of the main parameters of these glacier systems with climate change. To achieve this aim, we constructed vertical profiles of mass balance (accumulation and ablation) based both on meteorological observations for the mid to late 20th century and an ECHAM4 GCM scenario for 2040–2069. The observations and scenario were used for defining the recent and future equilibrium line altitude (ELA) for each glacier system. The altitudinal distributions of the areas covered with glacier ice were determined for present and future states of the glacier systems, taking into account the correlation of the change of the ELA and glacier-termini levels. We also give estimates of the possible changes of the areas and morphological structure of North-eastern Asia glacier systems and their mass balance characteristics from the ECHAM4 scenario. Finally, we compare characteristics of the continental and maritime glacier systems stability under conditions of global warming.

Economics terminology occupies a high position among the specialized terminologies. Economics terminology very often used in both professional and unprofessional media texts because it serves the modern Ukrainian social sphere. One of the main features of the economics terms functioning in modern electronic resources are variation of their content, appearance of additional connotative meaning and consequently change of the value evaluation scale, so that raises the question of the compliance of one of the main requirements for the term ― stylistic neutrality. The purpose of this article is to elucidate the features of the economics term using in the electronic mass media. In most cases the assessment of one or another phenomenon is clearly focused on the needs of the recipient. According to the terminological field theory (according to O.O. Reformatsky) the economics term can be properly and thoroughly explained in the economics paradigm when it place in the hierarchy of similar values is known. Therefore, in typical or atypical context, it can perform its function only if its affiliation with economics terminology is known. At this stage of the journalistic style development in the electronic mass media a number of both Ukrainian origin and borrowing the economics terms actively operates. There are two most general groups: terms used in the literal sense, that is, in it nominative and definitive functions and terms used figuratively, with acquired emotional and expressive coloring. Based on the fact that the main field of the terms usage is the area of functioning, the terms often acquire connotative coloring due to their combination with non-specific context or with general vocabulary. Most researchers of the special vocabulary emphasize that sometimes requirement of emotional and expressive term neutrality in practice not realized. For the economics term is not a prerequisite of communication barriers due to lack of understanding of its essence by recipient it should consider the obstacles that arise in the way of understanding in the process of communication. The semantic background of the economics term should be analyzed. It should be noted that there is the relation between the nature of semantization, degree of usage, “popularity” of the economics term and the need for its interpretation. Modern media, especially electronic, in our opinion, is one of the main social factors that form a stereotypical perception of the world in the mind of the recipient. It is important for the author to create an oriented “intellectual portrait of the audience” and to select appropriate language facilities for the thoughts expression. The specific features of the modern text of the electronic media are combination of the economics term with elements of spoken language, shoptalk, and sometimes with vulgarisms, barbarisms and slang for creating stylistic contrast. Quite frequently, there is an occasional and associative using of the economics terms to increase the expressivity of the text. Occasionalism which is formed by using the special unit becomes more accessible and understandable. These neologisms influence on the reader, and furthermore they confirm the author’s position on the object or phenomenon in question. Consequently, in most cases the appropriateness of the economics term usage explained by the need to have effective influence on the general reader. The leading trend of the economics terms usage in the modern electronic mass media is a combination of elements from different styles that as much as possible promote mutual understanding between the author and the recipient by means of electronic text.

Full textAbstract:
Velella velella is a pleustonic cnidarian noted worldwide for mass stranding of the colonial phase. Utilizing a 20 yr dataset (2000-2019; 23265 surveys) collected by the COASST citizen science program, we examined the spatio-temporal occurrence of mass strandings of V. velella along the Pacific Northwest coast from Washington to northern California, USA. V. velella mass strandings were documented in 14 years, with expansive events in 2003-2006 and 2014-2019. Events predominantly occurred in spring and were synchronous (April) among years, concurrent with shifts to prevailing onshore winds. Autumn mass stranding events occurred infrequently, with no consistent phenology (2005: November; 2014: August). In stranding years, reports of V. velella were mostly synchronous throughout the surveyed area, and events consistently spanned >400 km of coastline, with highest reporting rates in the vicinity of the Columbia River plume, collectively suggesting extensive V. velella blooms throughout the northern California Current system in some years. Annual metrics of spring V. velella reporting rate (proportion of beaches; January-June) were modeled as a function of indices representing sea surface temperature anomaly (SSTa), easterly (onshore) wind speed, and regional upwelling. The best models (based on Akaike’s information criterion corrected for small sample size) indicated that SSTa averaged over the preceding winter (December-February) was positively correlated with spring reporting rate, suggesting that mass strandings of V. velella may be more prevalent in warmer years. As planetary warming continues, and V. velella strandings are easily recorded by citizen science programs globally, we suggest that stranding prevalence may be one relatively easy measure providing evidence for epipelagic ecosystem response.

Full textAbstract:
Fluid-fluid interfacial area plays an important role for mass- and energy-transfer processes across the interface which is relevant in several hydrogeological and engineering applications, e.g. enhanced oil-gas recovery, CO2 storage in geological formations, unconventional geothermal systems, contaminant removal, etc. Kinetic interface sensitive tracers were designed to determine the size of the interface between two fluids by undergoing hydrolysis at the fluid-fluid interface. This study investigates by means of numerical modelling the influence of heterogeneity on the KIS tracer breakthrough curves in six idealized scenarios (S1-S6). It is an extension of the previous work conducted in “one-dimensional” column experiments by Tatomir et al. (2018) [1]. The changes in interfacial area are created by inclusion of heterogeneities at the Darcy-scale. The results show that KIS tracers can be used in two-dimensional experimental setup and can provide information about the size and dynamic evolution of interfacial area. Therefore, this is a first step for the dimensioning of an experimental flume.

Full textAbstract:
Drawing on the growth of non-profit investigative reporting centres in the United States, many of which are located in universities, this article proposes the creation of an Australia-New Zealand-Pacific network of university journalism students who collaborate to produce multi-media stories for a website. Tentatively called ‘UniMuckraker’, the project envisages that teaching with the ‘live ammunition’ of real journalism would provide an authentic, contextual and team-oriented approach to higher education learning experiences as well as producing quality journalistic content. In conceptualising the model, the article first examines contemporary trends in American investigative reporting with a focus on the increasing number and influence of non-profit centres that have been created following mass layoffs of journalists and closures in the established press. It finds a new willingness by mainstream media to collaborate with highly-specialised non-profit ‘factories’ that produce investigative stories but notes that the editor/publisher distinction is blurred further in the non-commercial model and that questions have been raised about the motives of the philanthropic funders of non-commercial investigative reporting.

Working electrodes were prepared by metallurgical process. 1 mol dm-3 and 0.5 mol dm-3 solutions of NaOH are chosen as the electrolyte. On the cyclic voltammograms, some current waves corresponding to number and quantity of phases present in the investigated electrodes appeared and they can be used for characterization of investigated alloy. On the voltammogram recorded for pure silver, two anodic and two cathodic peaks appeared. First peak consisted of two joined current waves which can be ascribed to the formation of the two different types of silver(I) oxide, Ag2O. Second peak should correspond to the formation of silver(II) oxide, AgO. Voltammogram obtained for pure copper exhibits one broad current wave corresponding to the formation of copper oxides, followed by a wide potential area in which copper is completely passive. At 0.4 V vs. SCE, current starts to increase again due to oxygen evolution and probably due to simultaneous dissolution of copper with formation of CuO22- as a product. In alkaline solutions copper has no significant influence on the shape and current values of the voltammograms recorded for Ag-Cu alloy; however, it has an influence only on the anodic and cathodic peak potentials, which are shifted to more negative values in comparison to Ag. It could mean an easier formation of oxides and their harder reduction. Comparing voltammograms recorded for Ag-Cu alloy in 0.5 moldm-3 NaOH and in 1 moldm-3 NaOH solutions, one can see that current waves appear at more positive potentials on the voltammograms obtained in the solution of lower concentration and with much higher current densities than those on the voltammograms obtained in the solution of higher concentration.

Full textAbstract:
Eutrophication caused by the entry of nutrients into a water body may lead to algal bloom. Russia possesses the world’s second highest supply of renewable freshwater resources and has faced the problem of eutrophication for many years. Nevertheless, as far as we know, no general analysis of Russia’s algal bloom situation has been before carried out. We have analyzed mass media and scientific reports about algal outbreaks from 2016 to 2018, which allowed us to determine the geographical distribution of algal blooms in Russia, as well as the major effects of eutrophication. As a result, we showed that algal blooms happened in all major climate zones and all federal districts. Cyanobacteria are the most frequently reported photosynthetic organisms comprising algal blooms in freshwater reservoirs located in the continental part of Russia and in the Baltic Sea. Dinoflagellate dominated blooms are more characteristic for the coastal parts of the northeastern Pacific Ocean. The largest number of reports comes from the south of the European part of Russia. However, we did not find significant correlations between state statistics data on factors possibly affecting eutrophication (e.g., population, arable land area, fertilizers, livestock, air temperature, etc.) and the number of algal outbreaks in the regions. Mass media analysis showed that algal blooms attract considerable public attention in Russia, which requires the scientific community to actively participate in solving the problem.

The effect of mycorrhizal fungi on growth and nutrient uptake during acclimatization and plant establishment of micropropagated guava plantlets (Psidium guajava L. cv. Media China) was determined. Half of the plantlets were inoculated with the endomycorrhizae isolate ZAC-19 and grown in a glasshouse for 18 weeks. The isolate ZAC-19 was collected from the Chihuahuan Desert in Zacatecas State, Mexico, and is a mixed isolate containing Glomus etunicatum and unknown Glomus spp. Plantlets were fertilized with modified Long Ashton nutrient solution containing 11 μg P/ml. Shoot length, leaf area, leaf number, and dry mass partitioning were positively affected by mycorrhizae compared to noninoculated plantlets; however, noninoculated plantlets had greater leaf area ratios and specific leaf area. Mycorrhizal plantlets generally had increased leaf tissue mineral levels, particularly P, Mg, Cu, and Mo. However, noncolonized plantlets had higher N, K, and Mn. At the end of the experiment, roots of inoculated guava plantlets had colonization levels of 94.3%.

Full textAbstract:
It is shown that the organization of co-current flow of the reacting gas during combustion synthesis of porous oxynitride materials leads to intensification of the process. The flow creates favorable conditions for directed heat and mass transfer in reacting media. It results in super-adiabatic heating of the products in the area of the combustion wave. Thus, macrokinetic parameters of the combustion synthesis exceed 10 % than the ones that had been obtained without forced filtering of gaseous reactant. Organization of the process in flowing of the reacting gas allows us to obtain materials with conversion ratio up to 0.95 under the combustion rates up to 0.8 mm/s and maximum temperature in the combustion wave up to 1900 °C.

Abstract. We studied contrasting glacier systems in continental (Orulgan, Suntar-Khayata and Chersky ranges located in the Pole of Cold of Eurasia area at the contact of Atlantic and Pacific influences and maritime (Kamchatka Peninsula) – under Pacific influence. Our purpose is to present a simple projection method to asses the main parameters of these glacier regions under climate change. To achieve this, constructed vertical profiles of mass balance (accumulation and ablation) based both on meteorological data for 1950–90s and ECHAM4 for 2040–2069 are used, the latter – as a climatic scenario. Also for selected key glacier systems other models were applied for comparison. The observations and scenarios were used to define the recent and future equilibrium line altitude (ELA) and glacier termini elevation for each glacier system. The altitudinal distributions of ice areas were determined for present and future, they were used for prediction of the elevation spreading of glaciers in the system taking into account the correlation between the ELA and glacier-termini level change. We tested two hypotheses of ice distribution versus altitude in mountain (valley) glaciers – linear and non-linear. The results are estimates of the possible changes of the areas and morphological structure of Northeastern Asia glacier systems and their mass balance characteristics for 2049–60. Finally, we compare characteristics of the stability of continental and maritime glacier systems under global warming.

Abstract The society is in a turmoil neither because globalization, high technology or immigration crises, but rather from the race of regional (China and Russia) or world power (US) to develop a new strategies to influence the countries. Europe is not bypassed by these phenomena because Russia as a regional actor is trying to create new sphere of influence at its periphery (especially in Baltic States, Poland and Romania). Romania, as NATO and European Union member, is one of the Russia’s targets not only because geographically it is in the Russia’s proximity, but because it is an area of American’s interests. Russia is developing a real hybrid war, using all the line of effort: political, economical, but specially the social one. The social field is covered by propaganda, promoted by mass-media, as a tool of political power. To counter-attack Russia’s hybrid war, NATO decided, at the Warsaw Summit to develop some operational lines, one is being strategic communication and the second is related with social resilience. The political, administrative and educational institutions are asked to apply this strategy, to find the way to educate people (almost via mass-media) in what is resilience and more important how it works when it is realized

Full textAbstract:
Density-driven free convection in porous media is highly affected by large-scale heterogeneity, typical of which are low- or high-permeability inclusions imbedded in homogeneous porous media. In this research, we applied the modified Elder problem to investigate the impact of low- or high-permeability inclusions on the migration of a dense, unstable salt plume. Sensitivity analyses were conducted in terms of the permeability contrast, the effective area (the area of the inclusion beneath the source zone), and the distance of the inclusion from the source zone, all of which were found to play a significant role in controlling the total mass flux released from the source into the media. Results show that (1) a high-permeability inclusion has stronger effects than low-permeability inclusion, due to significantly unbalanced solute distributions caused by accelerated solute transport, (2) the inclusion with a larger effective area has more potential to influence free convection, (3) free convection is more sensitive to the low-/high-permeability inclusion vertically closer to the source zone, and (4) free convection is more susceptible to the low-permeability inclusion horizontally closer to the source zone. For high-permeability inclusions, the inclusion horizontally closer to the source zone influences the transport process more significantly at the early stage, and conversely, the inclusion far from the source zone has a later impact. The results obtained could offer significant implications for understanding unstable density-driven flow and solute transport in porous media with structured heterogeneity.

Full textAbstract:
The object of study was precedent phenomena, or rather precedent names, and their functioning in modern Russian and French media discourse was considered as the subject of the study. Precedent names that perform appellative, cognitive, communicative, expressive, text-forming functions are strong elements of the text and are able to influence the mass consciousness. The frequency of their use in the materials of mass media discourse is steadily growing, which explains the relevance of the study. In the course of the study, the goal of analyzing precedent names was fulfilled, the comprehension of which requires referring to the cognitive context REAL ECONOMY, which is a component of a private matrix that includes the concept PERSONALITY as a core. Using the method of cognitive-matrix analysis to describe the components of the matrix as a system of cognitive contexts or conceptual areas, it was revealed that when comprehending a precedent name in relation to the context REAL ECONOMY, the cognitive contexts APPEARANCE, PSYCHE AND STATUS of the concept PERSONALITY are actualized. It is proved that the STATUS cognitive context when referring to the REAL ECONOMY conceptual area is most often interpreted. The study made it possible to draw a conclusion about the importance of the text-forming function of precedent names, which have become an effective tool for speech influence, and the importance of studying the cognitive mechanisms of their functioning.

Full textAbstract:
A greenhouse bioassay was used to compare the growth, ectomycorrhiza formation, and foliar nutrient concentrations of Douglas-fir seedlings grown in soils collected at different distances from hardwood species. Soil nutrient concentrations and bulk densities were also determined. The soils were collected from two southwestern Oregon sites that had been clear-cut and broadcast burned 5 years previously. The sites, poorly stocked with conifer reproduction, were occupied primarily by grasses, forbs, and scattered individuals of tanoak (Lithocarpusdensiflora (Hook. & Arn.) Rehd.), Pacific madrone (Arbutusmenziesii Pursh), and canyon line oak (Quercuschrysolepis Liebm.). Five-month-old seedlings grown in media containing mineral soil collected beneath hardwood crowns had on average 60% greater height, 2.2 times greater weight (roots plus shoots), and almost 2 times more total and ectomycorrhizal short roots than seedlings grown in media containing soil collected more than 4 m from a hardwood. Rhizopogon sp. and Cenococcumgeophilum dominated on seedlings grown in hardwood soils, and an unidentified brown ectomycorrhiza dominated on seedlings grown in open area soils. The effect of hardwoods did not vary among the three hardwood species or between the two sites. A study of soils collected at various distances from hardwoods indicated that the effect extended between 2 and 3 m. Average foliar nitrogen was higher for seedlings grown in hardwood area than in open area soils, but differences were not statistically significant. Differences in other foliar nutrients of seedlings grown on soils from beneath the three hardwood species were inconsistent. Differences in soil nutrient concentrations were also inconsistent; however, rates of mineralizable nitrogen (anaerobic) were from 2 to nearly 6 times higher in hardwood area than open area soils, and soil pH was higher. Results suggest that the pioneering hardwoods strongly influence soil biological activity in these clear-cuts and impose one or more soil patterns that favor establishment and growth of conifer seedlings.

Abstract. Multi-hazard events can be associated with larger socio-economic impacts than single-hazard events. Understanding the spatio-temporal interactions that characterize the former is therefore of relevance to disaster risk reduction measures. Here, we consider two high-impact hazards, namely wet and dry hydrological extremes, and quantify their global co-occurrence. We define these using the monthly self-calibrated Palmer Drought Severity Index based on the Penman–Monteith model (sc_PDSI_pm), covering the period 1950–2014, at 2.5∘ horizontal resolution. We find that the land areas affected by extreme wet, dry, and wet–dry events (i.e. geographically remote yet temporally co-occurring wet or dry extremes) are all increasing with time, the trends of which in dry and wet–dry episodes are significant (p value ≪ 0.01). The most geographically widespread wet–dry event was associated with the strong La Niña in 2010. This caused wet–dry anomalies across a land area of 21 million km2 with documented high-impact flooding and drought episodes spanning diverse regions. To further elucidate the interplay of wet and dry extremes at a grid cell scale, we introduce two new metrics: the wet–dry (WD) ratio and the extreme transition (ET) time intervals. The WD ratio measures the relative occurrence of wet or dry extremes, whereas ET quantifies the average separation time of hydrological extremes with opposite signs. The WD ratio shows that the incidence of wet extremes dominates over dry extremes in the USA, northern and southern South America, northern Europe, north Africa, western China, and most of Australia. Conversely, dry extremes are more prominent in most of the remaining regions. The median ET for wet to dry is ∼27 months, while the dry-to-wet median ET is 21 months. We also evaluate correlations between wet–dry hydrological extremes and leading modes of climate variability, namely the El Niño–Southern Oscillation (ENSO), Pacific Decadal Oscillation (PDO), and Atlantic Multi-decadal Oscillation (AMO). We find that ENSO and PDO have a similar influence globally, with the former significantly impacting (p value < 0.05) a larger area (18.1 % of total sc_PDSI_pm area) compared to the latter (12.0 %), whereas the AMO shows an almost inverse pattern and significantly impacts the largest area overall (18.9 %). ENSO and PDO show the most significant correlations over northern South America, the central and western USA, the Middle East, eastern Russia, and eastern Australia. On the other hand, the AMO shows significant associations over Mexico, Brazil, central Africa, the Arabian Peninsula, China, and eastern Russia. Our analysis brings new insights on hydrological multi-hazards that are of relevance to governments and organizations with globally distributed interests. Specifically, the multi-hazard maps may be used to evaluate worst-case disaster scenarios considering the potential co-occurrence of wet and dry hydrological extremes.

This study discusses the role of the media in conveying information which changes the perceptions, attitudes, and behavior of the audiences. National TV, mass media, and electronic media provide information on the spread of COVID-19 nationwide every day, thus giving a negative impact on tourism development. The tourists do not dare to move out of the area or even travel. This explains that the media can influence the interest of tourists to travel. On the other hand, information media related to COVID-19 aims to handle the spread of COVID-19 optimally. However, since the news of COVID-19, tourists are afraid to move or travel. Loyalty of tourists traveling has decreased. The purpose of this study was to determine the relationship between exposure to information on the COVID-19 pandemic on the interest and loyalty of tourists traveling. The data were collected using a questionnaire with a Likert scale measurement scale. While the data analysis technique uses smart PLS. The results of this study suggested 1) there was a positive and significant direct effect between information exposure on visiting interest, 2) there was no positive nor significant direct effect between information exposure on tourist loyalty, 3) there was no positive nor significant direct influence between visiting interest on loyalty of tourists traveling, and 4) there was an indirect effect between exposure to information on loyalty through tourist interest as a mediating variable.

Evaluating emergency risk communications is fraught with challenges since communication can be approached from both a systemic and programmatic level. Therefore, one must consider stakeholders' perspectives, effectiveness issues, standards of evidence and utility, and channels of influence (e.g., mass media and law enforcement). Evaluation issues related to timing, evaluation questions, methods, measures, and accountability are raised in this dialogue with emergency risk communication specialists. Besides the usual evaluation competencies, evaluators in this area need to understand and work collaboratively with stakeholders and be attuned to the dynamic contextual nature of emergency risk communications. Sample resources and measures are provided here to aid in this emerging and exciting field of evaluation.

Purpose The purpose of this study is to illustrate the influence of media coverage and sentiment about brands on user-generated content amplification and opinions expressed in social media. Design/methodology/approach This study used a mixed-method approach, using a brand situation as a case example, including sentiment analysis of social media conversations and sentiment analysis of media coverage. This study tracks the diffusion of a false claim about the brand via online media coverage, subsequent spreading of the false claim via social media and the resulting impact on sentiment toward the brand. Findings The findings illustrate the influence of digital mass communication sources on the subsequent spread of information about a brand via social media channels and the impact of the social spread of false claims on brand sentiment. This study illustrates the value of social media listening and sentiment analysis for brands as an ongoing business practice. Research limitations/implications While it has long been known that media coverage is in part subsequently diffused through individual sharing, this study reveals the potential for media sentiment to influence sentiment toward a brand. It also illustrates the potential harm brands face when false information is spread via media coverage and subsequently through social media posts and conversations. How brands can most effectively correct false brand beliefs and recover from negative sentiment related to false claims is an area for future research. Practical implications This study suggests that brands are wise to use sentiment analysis as part of their evaluation of earned media coverage from news organizations and to use social listening as an alert system and sentiment analysis to assess impact on attitudes toward the brand. These steps should become part of a brand’s social media management process. Social implications Media are presumed to be impartial reporters of news and information. However, this study illustrated that the sentiment expressed in media coverage about a brand can be measured and diffused beyond the publications’ initial reach via social media. Advertising positioned as news must be labeled as “advertorial” to ensure that those exposed to the message understand that the message is not impartial. News organizations may inadvertently publish false claims and relay information with sentiment that is then carried via social media along with the information itself. Negative information about a brand may be more sensational and, thus, prone to social sharing, no matter how well the findings are researched or sourced. Originality/value The value of the study is its illustration of how false information and media sentiment spread via social media can ultimately affect consumer sentiment and attitude toward the brand. This study also explains the research process for social scraping and sentiment analysis.

In the Gulf of Guinea, bigeye tuna (Thunnus obesus; BET) and yellowfin tuna (Thunnus albacares; YFT) are an important part of commercial fisheries and play a prominent ecological role as top predators. Using fatty acid profiles and carbon and nitrogen stable isotopes, we examined their trophic niche partitioning in this understudied region. Trophic niche overlap was high (>70%), similar to percentages in other ocean basins. BET occupied a higher trophic position than YFT and fed on deeper prey (high δ15N values and high proportions of monounsaturated fatty acids). The trophic position of YFT decreased slightly in the last 15 years (δ15N values decreased by ∼0.5‰), suggesting a change in epipelagic communities, as observed in the eastern Pacific Ocean. Ontogenic changes were limited to BET. For both species, the dietary proportion of the diatom marker 20:5(n-3) increased in the seasonal upwelling area, highlighting the influence of seasonal habitat on the diet of tuna. The relatively lipid-rich muscle (∼6% dry mass) of Atlantic tropical tuna suggests a richer diet in this region than that of Indian Ocean tropical tuna and (or) differences in energy allocation strategies.

Full textAbstract:
The migration law of shale gas has a significant influence on the seepage characteristics of shale, and the flow of the gas is closely related to the pore structure. To explore the influence of shale pore parameters on permeability in different diffusion zones, the pore structure of the shale in the Niutitang Formation in Guizhou, China, was analysed based on liquid nitrogen adsorption experiments and nuclear magnetic resonance experiments. The relationship among fractal dimension, organic carbon content (TOC) and BET-specific surface area was analysed based on the fractal dimension of shale pores calculated using the Frenkel–Halsey–Hill model. Shale permeability was calculated using the Knudsen number ( Kn ) and permeability equation, and the influence of the fractal dimension and porosity in different diffusion zones on shale permeability was analysed. Previous studies have shown that: (i) the pores of shale in the Niutitang Formation, Guizhou are mainly distributed within 1–100 nm, with a small total pore volume per unit mass, average pore diameter, large BET specific surface area and porosity; (ii) fractal dimension has a negative correlation with average pore diameter and TOC content and a quadratic relationship with BET specific surface area; and (iii) permeability has a positive correlation with Kn , porosity and fractal dimension. In the transitional diffusion zone, fractal dimension and porosity have a significant impact on permeability. In the Knudsen diffusion zone, porosity has no obvious effect on permeability. The methodologies and results presented will enable more accurate characterization of the complexity of pore structures of porous media and allow further understanding of the seepage law of shale gas.

Full textAbstract:
This study investigates the influence of citizens' socio-economic characteristics on the presence of social media in county-level government. E-government is ostensibly citizen-driven and therefore variation in an area's demographics would likely impact a government's utilization of emerging technology, such as social media. Despite its transformative potential and widespread adoption, e-government development beyond basic stages has been sluggish. Social media is transforming the nature of interaction among individuals and organizations and has the potential to overcome some of the restrictive challenges of e-government. Understanding if, how, and to what end governments are harnessing social media will help make e-government a citizen-driven, democratic, transparent, and trustworthy platform. County governments are challenged by their size, resource scarcity, heterogeneous service area (urban and rural), and varying population density; thereby preventing them from gaining a critical mass of online users. By exploring social media's role in e-government as related to citizen demographic factors, this study reveals an important paradoxical role of social media in government: operational ineffectiveness as a necessary precursor for exception events. Additional results reveal the presence of digital divide - counties with higher median household income and educational qualification tend to have social media presence in their e-government sites, which is also not related to population growth of the counties.

Full textAbstract:
Plant samples at the and of 1-st cutting were collected from field experiment or from teaching collection in order to determine the degree of relationship of in pairs of traits. The degree of the relationship between investigated was estimated by linear or curvilinear regresion and only equations for which coeficient of determination R<sup>2</sup> was greated than 0.5 were reported in the paper. Leave surface area from steams of compared species of papilionaceous depended to small degree on the shave of small leaves in this feature (<1/4 x) The magnitude of the total leave surface area depended on large, and mainly average leaves. Increasing number of leaves on the steam had a positive effect on total leave surface area, and moderate linear relation between features was observed (R<sup>2</sup>=0.70). The order of species according to their decreasing number of leaves on the steam is following: alfalfa-33,4 > bird's foot trefoi1-15,2 > red clover-7,9 > sainfoin-5,1. Between the mass of the steam of single species and its length curvilinear relation was observed, which informs about above average influence of longer steams (>70 cm) on yield. Plant mass was poorly correlated with the total steam length. Among single plants (small, average, large) significant differences were observed in the mass of single steams. Share of separated groups of steams in the mass of tops varied greatly and was following: 25% of largest steams decided about the half of its yield. In turn 50% of steams (small and very small) formed only 25% of top yield.

Abstract. In spring 2002, an atmospheric measurement site was established at the peak of Whistler Mountain in British Columbia, Canada to measure trace gases, particle chemistry and physics, and meteorology. This paper uses continuous measurements from March 2002 to December 2006 to investigate the influence of trans-Pacific transport and North American forest fires on both O3 and CO at Whistler. Annual mean mixing ratios of O3 and CO were 41 ppbv (monthly means of 35–48 ppbv) and 145 ppbv (monthly means of 113–177 ppbv) respectively with both species exhibiting an annual cycle of late-winter to early-spring maxima and summer minima. The absence of a broad summer O3 peak differs from previously-reported high altitude sites in the western US. The highest monthly-averaged O3 and CO mixing ratios relative to the 5-yr monthly means were seen in fall 2002 and spring 2003 with increased O3 and CO of 10 % and 25 % respectively. These increases correspond to anomalously-high values reported at other Northern Hemisphere sites and are attributed to fires in the Russian Federation. Air mass back trajectory analysis is used to associate the mean enhancements of O3 and CO with trans-Pacific transported or North American air masses relative to the Pacific background. Mean values of the enhancements for March to June in trans-Pacific air masses were 6 ppbv and 16 ppbv for O3 and CO respectively. In summers 2002–2006, higher CO and O3 mixing ratios were almost always observed in North American air masses and this relative enhancement co-varied for each year with the western US and Canada total wildfire area. The greatest enhancements in O3 and CO were seen in 2004, a record year for forest fires in Alaska and the Yukon Territory with average O3 and CO mixing ratios 13 and 43 ppbv above background values.

Abstract. Measurement of atmospheric carbon dioxide (CO2) is indispensable for top-down estimation of surface CO2 sources/sinks by an atmospheric transport model. Despite the growing importance of Asia in the global carbon budget, the region has only been sparsely monitored for atmospheric CO2 and our understanding of atmospheric CO2 variations in the region (and thereby that of the regional carbon budget) is still limited. In this study, we present climatological CO2 distributions over the Asia-Pacific region obtained from the CONTRAIL (Comprehensive Observation Network for TRace gases by AIrLiner) measurements. The high-frequency in-flight CO2 measurements over 10 years reveal a clear seasonal variation in CO2 in the upper troposphere (UT), with a maximum occurring in April–May and a minimum in August–September. The CO2 mole fraction in the UT north of 40∘ N is low and highly variable in June–August due to the arrival of air parcels with seasonally low CO2 caused by the summertime biospheric uptake in boreal Eurasia. For August–September in particular, the UT CO2 is noticeably low within the Asian summer monsoon anticyclone associated with the convective transport of strong biospheric CO2 uptake signal over South Asia. During September as the anticyclone decays, a spreading of this low-CO2 area in the UT is observed in the vertical profiles of CO2 over the Pacific Rim of continental East Asia. Simulation results identify the influence of anthropogenic and biospheric CO2 fluxes in the seasonal evolution of the spatial CO2 distribution over the Asia-Pacific region. It is inferred that a substantial contribution to the UT CO2 over the northwestern Pacific comes from continental East Asian emissions in spring; but in the summer monsoon season, the prominent air mass origin switches to South Asia and/or Southeast Asia with a distinct imprint of the biospheric CO2 uptake. The CONTRAIL CO2 data provide useful constraints to model estimates of surface fluxes and to the evaluation of the satellite observations, in particular for the Asia-Pacific region.

Objectives To determine whether metabolic phenotype is associated with the change in carotid intima-media thickness (CIMT) in patients undergoing bariatric /metabolic surgery (BMS). Methods We performed a case-control study of BMS candidates who had metabolically unhealthy obesity (MUO) or metabolically healthy obesity (MHO). We measured the change in CIMT during the 9 months following BMS. The plasma tumor necrosis factor-α, interleukin-1β, adiponectin, leptin, nitric oxide (NO), vascular endothelial growth factor A (VEGF-A), and malondialdehyde concentrations were determined, adipocyte area was measured histologically, and adipose tissue area was estimated using computed tomography. Results Fifty-six patients (mean age 44.5 years, mean body mass index 44.9 kg/m2, 53% women, and 53% had MUO) were studied. Nine months following BMS, the MUO phenotype was not associated with a significant reduction in CIMT, and that of the MHO group was larger. In addition, fewer participants achieved a 10% reduction in CIMT in the MUO group. A CIMT reduction was associated with lower VEGF-A and NO in the MUO group, while that in the MHO group was associated with a higher NO concentration. Conclusion The metabolic phenotype of patients may influence their change in CIMT following BMS, probably through circulating vasodilatory and pro-inflammatory molecules.

Evoliucionuojant medijoms požiūriai į auditorijas nuolat kito. Auditorijos kaip kolektyvinės medijų pranešimų gavėjos savo esme yra itin dinamiškos ir kintančios struktūros. Kiekviena naujai atsirandanti medija darė įtaką auditorijų kaitos procesams ir skatino mokslininkus iš naujo įvertinti auditorijas formuojančius veiksnius bei persvarstyti jų sampratos aktualumą.Straipsnyje nagrinėjama, kaip kito auditorijų samprata per visą studijų laikotarpį, ir klausiama, kokios auditorijos koncepcijos gyvuoja šiandien, kai iškyla medijų auditorijos, veikiančios daugiakanalėje daugialypės terpės erdvėje.Reikšminiai žodžiai: publikos, minia, masės, auditorijos, masinė auditorija, naujosios medijos, konvergencija, medijų naudotojai, medijų auditorijos.Shifts of the audience’s paradigmsDaiva SiudikienėSummaryThis paper reveals the main theoretical approaches which influence the construction and shifts of the audience’s paradigms. The audience studies developed eventually under the influence of contradictory theoretical perspectives. It was stated that the significant processes had started long before the academic discipline formation, but intellectual discussions on the reflections of the massification processes were significant for developing the theoretical background for further audience studies. Contemplations on such concepts as public, crowd, mass, mass society, mass audience are closely related to the traditions of political theory, social philosophy and cultural history of the late 19th and the 20th centuries. Development of the communication sciences measures more than one hundred years, but the audience as an equivalent participator of the communication process had been recognized only at the end of the 20th century. For a long time, the audiences had been approached as unqualified and unable to evaluate the media production properly. Therefore, the conception of audience as the market dominated throught a couple of decades and formed the research traditions of the audience as a quantitatively measured object. The extent remains the most significant indicator in this research area, but the audience studies have generated much more concepts. Side by side with the citizens audience, there emerged the notions of the interpretive communities and lifestyle audiences. The recognition of the fact that the audience members differ in their socio-cultural and national characteristics, knowledge, experience in the use of media and other aspects, clarification of this notion remain a complicated matter. The most important facet should be the point that the individuals realize their role differently as an audience, but all together they are in the process of creating the cognitive schemes and the collective ideals as a certain united community. The rise of the new media has generated unprecedented processes in the post-modern societies and new notions applied for media users. It was stated that, despite the media explosion and the audience fragmentation, this term remains relevant. The new media environment is recasting the notion of audience for covering a wide range and multifaceted activities of media users. Therefore, the new roles of media users are under consideration. According to the author of this paper, as the most meaningful concepts should be recognized those that indicate the creative potential of the audience.

Full textAbstract:
Multiple shock compactions of powder media within a die with a rigid punch are theoretically investigated. First, similarity of dynamic compaction processes for a powder medium of a simple type is exhibited through nondimensionalized one-dimensional equations. The similarity is established after determination of three parameters, i.e., the ratio S* of the lateral surface to the cross-sectional area of the medium, the ratio M* of the mass of the punch to that of the powder medium filled in the die, and the compaction energy per unit powder volume e. The similarity indicates that the particle velocity, specific volume and pressure have the same variation with respect to nondimensional time at all points in the medium with various cross-sections and initial lengths so long as S* is kept fixed at a certain value, i.e., at the same proportional nondimensional point in the medium. The density distributions of the green compacts are necessarily identical, and so is the mean density in all compactions. Second, it is shown in one of the nondimensionalized equations that wall frictional influence in a compaction where S* → 0 is not present, while the wall frictional influence is extremely large when S* is very large, which implies that the mean densities of the compacts are larger in compactions with smaller S*. Two types of compactions can be obtained for any powder medium because the equation used is applicable to any medium.

The purpose of the current study was threefold: a) to collect a very large representative sample of adolescents and assess for their levels of disordered eating behaviors; b) to describe the characteristics of adolescents with disordered eating behaviors in Cyprus based on the measures that were used in the study and c) to compare the adolescents with significant disordered eating behaviors (EAT-26 ≥ 20) to the ones without any disordered eating behaviors (EAT < 20) on all the variables of interest. A total of 2664 secondary school students responded to self-report measures assessing disordered eating, negative body image, situational dysphoria, self-esteem and media influences. Results indicated that 16.04% of the overall sample of adolescents scored significantly on the EAT-26 (21.4% of females and 8.4% of males). Results also indicated that the majority of the adolescents with disordered eating behaviors were female, mainly from average socioeconomic status, normal Body Mass Index and grew up and reside in an urban area. Finally, adolescents in the disordered eating behaviors group scored significantly lower on appearance satisfaction and self-esteem and significantly higher on appearance investment, weight-related anxiety, situational dysphoria, internalization of the thin and athletic ideals as well as feeling pressured from the media and considering the media as a good source of information. In conclusion, results indicate a substantial difference in levels of disordered eating in adolescents as compared to previous research in Cyprus. Possible explanations are addressed as well as implications for prevention strategies and future research ideas based on the findings.

Full textAbstract:
2D numerical modeling algorithms of multi-component, multi-phase filtration processes of mass transfer in frost-susceptible rocks using nonlinear partial differential equations are a valuable tool for problems of subsurface hydrodynamics considering the presence of free gas, free water, gas hydrates, ice formation and phase transitions. In this work, a previously developed one-dimensional numerical modeling approach is modified and 2D algorithms are formulated through means of the support-operators method (SOM) and presented for the entire area of the process extension. The SOM is used to generalize the method of finite difference for spatially irregular grids case. The approach is useful for objects where a lithological heterogeneity of rocks has a big influence on formation and accumulation of gas hydrates and therefore it allows to achieve a sufficiently good spatial approximation for numerical modeling of objects related to gas hydrates dissociation in porous media. The modeling approach presented here consistently applies the method of physical process splitting which allows to split the system into dissipative equation and hyperbolic unit. The governing variables were determined in flow areas of the hydrate equilibrium zone by applying the Gibbs phase rule. The problem of interaction of a vertical fault and horizontal formation containing gas hydrates was investigated and test calculations were done for understanding of influence of thermal effect of the fault on the formation fluid dynamic.

Full textAbstract:
In times of genetically modified food, globalized production and distribution chains, food safety is a major issue in public policy. Although industrial actors have traditionally had remarkable influence on political decision-making in this area, challenger organizations from civil society have gained influence by mobilizing support and shaping public discourse on the Internet. The authors' study analyzes online issue networks concerning food safety in order to assess the actor constellations and coalitions that may serve as an opportunity structure for the mobilization of the issue. By comparing the US, the UK, Germany, and Switzerland, the authors investigate the differences in policy settings between pluralist and corporatist democracies. They find that the mobilization structures related to food safety issues are actively promoted by the challengers themselves. In countries where challengers do not find support within national politics, the challengers' online communication refers to mass media as witnesses to legitimize their concern in public debates.
