The Significance of Macronutrients in Alternate Bearing ‘Nadorcott’ Mandarin Trees
Authors: Stander Ockert P.J. , Barry Graham H. , Cronjé Paul J.R.
Published: November 2018

The significance of macronutrients nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), and magnesium (Mg) in leaves was studied in relation with their possible roles in alternate bearing of ‘Nadorcott’ mandarin (Citrus reticulata) trees over a period of three seasons. Fruit load (“on,” a heavy fruit load, vs. “off,” a light fruit load) affected the leaf macronutrient concentrations, and the amount of macronutrients removed through the harvest of fruit, i.e., the crop removal factor (g·kg−1), was consistent in both seasons. The crop removal factors were higher for each macronutrient in “off” trees—harvest of 1 kg fruit removed ≈2.3 g·kg−1 N, 0.3 g·kg−1 P, 3.1 g·kg−1 K, 1.0 g·kg−1 Ca, and 0.4 g·kg−1 Mg, compared with 1.3 g·kg−1 N, 0.2 g·kg−1 P, 1.7 g·kg−1 K, 0.6 g·kg−1 Ca, and 0.2 g·kg−1 Mg in “on” trees. Fruit load per tree (kg/tree) of 84, 110, and 52 kg/tree in “on” trees, however, removed ≈217 g/tree N, 28 g/tree P, 296 g/tree K, 100 g/tree Ca, and 35 g/tree Mg, which was 1.5–6 times more than that of fruit loads of 14, 71, and 16 kg/tree in “off” trees. In “off” trees, N, P, and K, and in “on” trees, Ca accumulated in leaves to between 20% and 30% higher concentrations in season 1, but the higher macronutrient status did not manifest in or consistently correlate with intensity of summer vegetative shoot development in the current season, or intensity of flowering in the next season, the two main determinants of fruit load in ‘Nadorcott’ mandarin. Apart from some anomalies, the concentrations of macronutrients in leaves were unaffected by de-fruiting and foliar spray applications of N and K to “on” trees, and showed no consistent relationship with treatment effects on parameters of vegetative shoot development and flowering. Leaf macronutrients in alternate bearing ‘Nadorcott’ mandarin trees, fertilized according to grower standard practice, are not related to differences in flowering and vegetative shoot development, and appear to be a consequence of fruit load and not a determinant thereof.

Published: November 2018

Understanding how consumer perception is related to physiochemical attributes assists in the identification of harvest and marketability parameters for muscadine grapes (Vitis rotundifolia Michx.). Three muscadine cultivars (Ison, Nesbitt, and Summit) and three advanced breeding selections (AM-9, AM-74, and AM-83) were harvested from vines at the University of Arkansas System Division of Agriculture Fruit Research Station in Clarksville, AR. The physiochemical (physical and composition) and sensory attributes (descriptive) of the genotypes were evaluated at harvest. Significant differences between genotypes were observed for berry weight (9.25–14.38 g), soluble solids (12.73% to 15.40%), pH (2.88–3.33), titratable acidity (0.54% to 1.01%), soluble solids/titratable acidity ratio (13.12–28.49), skin firmness [0.85–1.48 Newtons/millimeters (N·mm−1)], and flesh firmness (0.89–2.14 N). Total sugars (6.17–9.75 g/100 g) and total organic acid (0.50–0.84 g/100 g) levels were not significantly different for these genotypes. A trained descriptive sensory panel (n = 8) evaluated the fruit attributes for aroma (n = 9), external appearance (n = 7), internal appearance (n = 3), basic tastes (n = 3), aromatics (n = 10), feeling factors (n = 2), and texture (n = 7). The descriptive sensory panel detected differences among genotypes for external appearance, internal appearance, and basic taste attributes, more specifically with desirable attributes rather than unfavorable. However, the panelists found no differences among genotypes for texture attributes. Of the physiochemical attributes, total sugars had the most significant correlations with the descriptive sensory attributes, followed by soluble solids/titratable acidity ratio. Total sugars were correlated to 12 attributes (three aromas, two exterior appearances, two basic tastes, four aromatics, and one feeling factor) and soluble solids/titratable acidity was correlated to five attributes (one aroma, one basic taste, two aromatics, and one feeling factor). A lexicon of terms for descriptive sensory attributes for fresh-market muscadine grapes was established. This lexicon can be used for other research and breeding efforts, as well as establishing the relationship between the physiochemical and descriptive sensory attributes.

Published: November 2018

Tomato (Solanum lycopersicum L.) is a warm-season, cold-sensitive crop that shows slower growth and development at temperatures below 18 °C. Improving suboptimal temperature tolerance would allow earlier planting of field-grown tomato and a reduction in energy inputs for heating greenhouses. Grafting tomato onto high-altitude Solanum habrochaites (S. Knapp and D.M. Spooner) accessions has proven effective at improving scion suboptimal temperature tolerance in limited experiments. This study was conducted to determine whether commercially available tomato rootstocks with differing parental backgrounds and root system morphologies can improve the tolerance of scion plants to suboptimal temperature. Two controlled environment growth chambers were used and maintained at either optimal (25 °C day/20 °C night) or suboptimal (15 °C day/15 °C night) temperatures. The cold-sensitive tomato cultivar Moneymaker was used as the nongrafted and self-grafted control as well as scion grafted on ‘Multifort’ (S. lycopersicum × S. habrochaites), ‘Shield’ (S. lycopersicum), and S. habrochaites LA1777 rootstocks. Plants were grown for 10 days in 3.8 L plastic containers filled with a mixture of calcined clay and sand. ‘Multifort’ rootstock significantly reduced the amount of cold-induced stress as observed by larger leaf area and higher levels of CO2 assimilation and photosystem II quantum efficiency. ‘Multifort’ had significantly longer roots, having 42% to 56% more fine root (diameter less than 0.5 mm) length compared with the other nongrafted and grafted treatments. Leaf starch concentration was significantly lower in ‘Multifort’-grafted plants at suboptimal temperatures compared with the self-grafted and nongrafted controls and the ‘Shield’-grafted plants at the same temperature. The ability for ‘Multifort’ to maintain root growth at suboptimal temperatures may improve root system sink strength, thereby promoting movement of photosynthate from leaf to root even under cold conditions. This work demonstrates that a commercially available rootstock can be used to improve suboptimal temperature tolerance in cold-sensitive ‘Moneymaker’ scions.

Published: November 2018

The increasing scarcity of land and water for agriculture mandates an efficient use of these natural resources. Establishment of high-density orchards with the use of a size-controlling rootstock, in combination with a suitable canopy architecture, is an efficient method for fruit production. However, less attention has been paid to the use of size-controlling practices such as trunk girdling in these modern orchard systems. The impacts of two rootstocks, two tree architectures, and three levels of bark cambium cuts (girdling or scoring) on growth, yield, fruit quality attributes at harvest, and leaf nitrogen (N) in ‘Aztec Fuji’ apple (Malus domestica Borkh.) were studied in 2015 and 2016. Trees on Nic 29 had larger canopies, higher yields, and larger fruit, but lower fruit color, sunburn, and firmness than those on Bud 9. Trees with a tall spindle (TS) architecture had higher yield in 2016, higher fruit soluble solids and firmness in 2015, higher fruit russet in 2016, but shorter terminal growth in both 2015 and 2016 and lower leaf N in 2015 than did those with a central leader (CL) training system. Trees receiving a bark girdling in 2015 (BG15) or score girdling in 2015 and 2016 (SG1516) had significantly higher yield than trees on nongirdled trees (NOGD) in 2016. Bark girdling or score girdling in 2015 (BG15 or SG15) increased fruit weight (size), color, and firmness at harvest in the same year, although differences for score girdling were not always significant. However, BG15 or SG15 did not have a “carryover” effect and did not affect fruit size, color, or firmness at harvest in 2016. When bark scoring was repeated in 2016 (SG1516), fruit size was increased in 2016. On the basis of the results of this 2-year study, it appears that bark girdling in one year is sufficient to increase fruit size of the current year and the yield in the following year. If larger fruit size is the critical objective of fruit production, annual score girdling needs to be practiced. However, a further long-term study is needed to monitor the carryover effects of cambium girdling and scoring on tree performance and fruit quality attributes in the subsequent years.
Drought Avoidance Traits in a Collection of Zoysiagrasses
Authors: Jespersen David , Schwartz Brian
Published: November 2018

Drought avoidance is dictated by a collection of traits used to maintain tissue hydration levels and turgidity during water-limited conditions. These traits include deeper and more extensive rooting and the closure of stomata to limit the transpiration of water from leaves. Zoysiagrasses are a group of warm-season turfgrasses, including Zoysia japonica and Zoysia matrella, that are valued for their turfgrass quality; however, they are susceptible to drought relative to other warm-season turfgrass species. The objectives of the study were to determine 1) differences in drought avoidance among a collection of zoysiagrasses and 2) which drought avoidance traits contributed to these differences. Fifteen zoysiagrass genotypes were exposed to either drought or control conditions in a greenhouse environment. Overall performance was assessed by evaluating turfgrass quality and percentage green cover. Drought avoidance was estimated by measuring leaf hydration levels and drought avoidance traits [including stomatal conductance (gS)]; root traits such as total root biomass, specific root length (SRL), and root length density (RLD) were measured. Compared with commercial cultivars Meyer, Palisades, or Zeon, some experimental genotypes maintained greater turfgrass quality during drought, with experimental genotype ‘09-TZ-54-9’ having a quality rating of 7.8 after 20 days of drought compared with 5.3 in ‘Zeon’, 5.2 in ‘Meyer’, and 5.0 in ‘Palisades’. A range of belowground traits such as root biomass was also found to be associated with drought avoidance, with experimental ‘09-TZ-53-20’ having 1.03 total grams, and 2.39 total grams in ‘10-TZ-1254’, compared with 1.14, 1.66, and 3.44 total grams in ‘Meyer’, ‘Zeon’, and ‘Palisades’, respectively. Significant differences in drought avoidance were found among the 15 genotypes, with both belowground rooting traits and aboveground factors affecting transpiration influencing plant performance.
Investigation of the characteristics of the internal firefighting water pipeline elements
Authors: Meleshchenko Ruslan
Published: November 2018

An important task in the design of buildings for different purposes is ensuring the safety of people's livelihoods. To protect them from the negative factors of fire, various devices are used to localize and stop burning. One of the elements of the fire protection of the building is the internal firefighting water supply. For the supply of water to extinguish a fire, it is provided for the installation of firefighting hydrants sets with a diameter of 25 and 33 mm. To date, there is no clear procedure for selecting fire hydrant equipment of small diameter for different types of buildings. To formulate the requirements for them, the influence of various factors on the actual flow of water is investigated. According to the results of the experiment, empirical dependences of water consumption for semi-rigid hoses are obtained. Analysis of the simulation results shows that the actual flow of water from a fire hydrant largely depends on the pressure in the network and the diameter of the hose. A comparison of actual water consumption with regulatory data is done. The inexpediency of the use of equipment, whose characteristics do not provide the necessary indicators, is shown. A 3-step procedure for selecting the characteristics of a fire hydrant is proposed, including determining the flow rate of water from a fire hydrant for semi-rigid hoses of different lengths, degree of deployment and arbitrary pressure values in the water supply network. The result is compared with the standard value. The proposed procedure allows to reasonably choose the equipment that can ensure the successful extinguishing of the fire. Its practical value is reducing the flow of water to extinguish a fire and reduce material losses
Exact large-scale correlations in integrable systems out of equilibrium
Authors: Doyon Benjamin
Published: November 2018

Using the theory of generalized hydrodynamics (GHD), we derive exact
Euler-scale dynamical two-point correlation functions of conserved
densities and currents in inhomogeneous, non-stationary states of
many-body integrable systems with weak space-time variations. This
extends previous works to inhomogeneous and non-stationary situations.
Using GHD projection operators, we further derive formulae for
Euler-scale two-point functions of arbitrary local fields, purely from
the data of their homogeneous one-point functions. These are new also in
homogeneous generalized Gibbs ensembles. The technique is based on
combining a fluctuation-dissipation principle along with the exact
solution by characteristics of GHD, and gives a recursive procedure able
to generate nn-point
correlation functions. Owing to the universality of GHD, the results are
expected to apply to quantum and classical integrable field theory such
as the sinh-Gordon model and the Lieb-Liniger model, spin chains such as
the XXZ and Hubbard models, and solvable classical gases such as the
hard rod gas and soliton gases. In particular, we find
Leclair-Mussardo-type infinite form-factor series in integrable quantum
field theory, and exact Euler-scale two-point functions of exponential
fields in the sinh-Gordon model and of powers of the density field in
the Lieb-Liniger model. We also analyse correlations in the partitioning
protocol, extract large-time asymptotics, and, in free models, derive
all Euler-scale nn-point
functions.
Research of market development of intelligent transport systems in the world
Authors: Katerna Olga
Published: November 2018

The issues of the development of intelligent transport systems (ITS) in the world as an instrument for ensuring social and economic growth of the state have been investigated. The essence and role of the structure of management of intellectual systems in different countries has been described and common features of their implementation have been determined. To solve the research problems, the following methods have been applied: systematic, dialectic, synthesis and generalization and scientific abstraction. To achieve the goal in the research methods have been applied on the systems approach, management theory and decision theory. System analysis has been used to identify the scientific problem. The results of the investigation have allowed the author to determine that there are problems with increasing traffic in large cities, high accident rates, high traffic growth, poor quality of traffic management, transport services, and how ITS helps to solve these problems. The results of the analysis have proved that mechanisms of ITS implementation in different countries is differ, but the key elements can be watch common: public private partnership; presence in the developed countries of the world of priority programs for the development of ITS; mandatory formation of uniform unified standards; the creation of a state coordinating body whose main function is to protect and promote the interests of the country and beyond its borders; the creation of independent groups or organizations (the majority on the basis of scientific institutions) such as “ITS America”, “ERTICO” in Europe, “ITS Japan”; industrial base in the field of development as a technical and information component, as well as cooperation in developing or participating in the field of geoinformation support. It is important to conduct an analysis of the ITS market volume in the world in 2008 – 2017 years in mln. dol. USA and a detailed analysis of the geography distribution in 2017. The implementation of the ITS begins with institutional changes, so giving them the status of a national project and developing the appropriate state program for the creation of multi-year development plans that have the goal of developing science and technology in the country can form the basis for a recommendation when implementing ITS in Ukraine.
Approaches to measuring resilience and their applicability to small retail business resilience
Authors: Kativhu Simbarashe , Mwale Marizvikuru , Francis Joseph
Published: November 2018

The resilience concept has attracted interest across many fields in the recent years. The interdisciplinary nature of the concept has led to the existence of numerous definitions, interpretations and measurement approaches. For this reason, there is no acceptable universal understanding of resilience across disciplines. Even though the concept is conceptualized differently in the small retail business field, scholars seem to commonly relate resilience to the ability of business to adapt to disruptions that threaten existence. However, resilience measuring has been a highly contested aspect in the sector. As such, neither key resilience attributes nor universally applicable criteria for resilience measuring exist in the small retail sector. At the same time, small retail businesses are increasingly exposed to direct and indirect threats that jeopardize their resilience prowess. Therefore, it is vital to develop approaches for assessing resilience levels and monitor changes over time. This paper critically examines current approaches to developing resilience measurement tools. Thereafter, it proposes the most applicable approach for developing performance measures of resilience for use in the small retail business sector. A review of key frameworks for resilience measuring within climate, community, livelihoods, organizational and business sectors was conducted. Frameworks and approaches for resilience measuring that has been in use in the past decade and half were selected. The main focus was on exploring methodological aspects, resilience attributes and variations in the interpretation of the resilience concept within different frameworks. It was revealed that the generic application of frameworks for resilience measuring in the small retail business sector is not appropriate. Thus, there is a need for developing contextualized frameworks to guide resilience measurement in the small retail sector.

Published: November 2018

The possibility of using the RNA interference (RNAi) mechanisms in gene therapy was one
of the scientific breakthroughs of the last century. Despite the extraordinary therapeutic potential of
this approach, the need for an efficient gene carrier is hampering the translation of the RNAi technology
to the clinical setting. Although a diversity of nanocarriers has been described, liposomes continue
to be one of the most attractive siRNA vehicles due to their relatively low toxicity, facilitated siRNA
complexation, high transfection efficiency and enhanced pharmacokinetic properties.

This review focuses on RNAi as a therapeutic approach, the challenges to its application, namely the
nucleic acids’ delivery process, and current strategies to improve therapeutic efficacy. Additionally,
lipid-based nanocarriers are described, and lessons learned from the relation between biophysical
properties and biological performance of the dioctadecyldimethylammonium:monoolein (DODAX:
MO) system are explored.

Liposomes show great potential as siRNA delivery systems, being safe nanocarriers to protect nucleic
acids in circulation, extend their half-life time, target specific cells and reduce off-target effects. Nevertheless,
several issues related to delivery must be overcome before RNAi therapies reach their full
potential, namely target-cell specificity and endosomal escape. Understanding the relationship between
biophysical properties and biological performance is an essential step in the gene therapy field.

Authors: Bozbey İrem , Sari Suat , Şalva Emine , Kart Didem , Karakurt Arzu
Published: November 2018

Background:

Azole antifungals are among the first-line drugs clinically used for the
treatment of systemic candidiasis, a deadly type of fungal infection that threatens mostly immunecompromised
and hospitalized patients. Some azole derivatives were also reported to have
antiproliferative effects on cancer cells.

Objective:

In this study, 1-(4-trifluoromethylphenyl)-2-(1H-imidazol-1-yl)ethanone (3), its oxime
(4), and a series of its novel oxime ester derivatives (5a-v) were synthesized and tested for their in
vitro antimicrobial activities against certain ATCC standard strains of Candida sp. fungi and
bacteria. The compounds were also tested for their cytotoxic effects against mouse fibroblast and
human neuroblastoma cell lines. Molecular modeling studies were performed to provide insights into
their possible mechanisms for antifungal and antibacterial actions.

Methods:

The compounds were synthesized by the reaction of various oximes with acyl chlorides.
Antimicrobial activity of the compounds was determined according to the broth microdilution
method. For the determination of cytotoxic effect, we used MTS assay. Molecular docking and
QM/MM studies were performed to predict the binding mechanisms of the active compounds in the
catalytic site of C. albicans CYP51 (CACYP51) and S. aureus flavohemoglobin (SAFH), the latter
of which was created via homology modeling.

Results:

5d, 5l, and 5t showed moderate antifungal activity against C. albicans, while 3, 5c, and 5r
showed significant antibacterial activity against Staphylococcus aureus and Pseudomonas
aeruginosa. Most of the compounds showed approximately 40-50% inhibition against the human
neuroblastoma cells at 100 µM. In this line, 3 was the most potent with an IC50 value of 82.18 μM
followed by 5a, 5o, and 5t. 3 and 5a were highly selective to the neuroblastoma cells. Molecular
modelling results supported the hypothesis that our compounds were inhibitors of CAYP51 and
SAFH.

Conclusion:

This study supports that oxime ester derivatives may be used for the development of
new antimicrobial and cytotoxic agents.

Published: November 2018

Background:

Obesity is well known multifactorial disorder towards the public health concern in front of the world. Increasing rates of obesity are characterized by liver diseases, chronic diseases, diabetes mellitus, hypertension and stroke, improper function of the heart, reproductive and gastrointestinal diseases, and gallstones. An essential enzyme pancreatic lipase recognized for the digestion and absorption of lipids can be a promising drug target towards the future development of antiobesity therapeutics in the cure of obesity disorders.

Objective:

The purpose of present study is to identify an effective potential therapeutic agent for the inhibition of pancreatic lipase.

Methods:

A trio of in-silico procedure of HTVS, SP and XP in Glide module, Schrodinger with default parameters, was applied on Specs databases to identify the best potential compound based on receptor grid. Finally, based on binding interaction, docking score and glide energy, selected compounds were taken forward to the platform of IFD, ADME, MMGBSA, DFT, and MDS for analyzing the ligands behavior into the protein binding site.

Results:

Using in silico protocol of structure-based virtual screening on pancreatic lipase top two compounds AN-465/43369242 & AN-465/43384139 from Specs database were reported. The result suggested that both the compounds are competitive inhibitors with higher docking score and greatest binding affinity than the reported inhibitor.

Conclusion:

We anticipate that results could be future therapeutic agents and may present an idea toward the experimental studies against the inhibition of pancreatic lipase.
Computing efficiency of the three-stage interpolated low pass filters
Authors: Savinykh I. S. , Chemasov D. A.
Published: November 2018

Undoubted advantages of finite impulse response filters are their unconditional stability, the absence of limit cycles and the possibility of implementing a filter that does not introduce phase distortion. The disadvantage of such filters is the large cost required to compute the response. This paper considers three-stage interpolated finite impulse response low-pass filters. The maximum values of the interpolation factors are determined. Dependences of the coefficient of computational efficiency and the coefficient of increase in the registers of the three-stage interpolated low-pass filter on the values of the interpolation factors, the widths of the passband and the transition band are obtained. Relations for determining the optimal values of interpolation factors corresponding to the maximal value of computational efficiency coefficient are obtained. In addition, the dependencies of the maximum coefficient of computational efficiency and the optimal coefficient of increase in the registers of the three-stage interpolated low-pass filter on the widths of the passband and the transition band at the optimum values of the interpolation factors are obtained. Considered three-stage interpolated low-pass filters should be used in the case when the required stopband is significantly less than the sampling rate. In this case, three- stage interpolated filters require less computational resources for calculating the response than the two-stage interpolated filters or filter implemented by the transversal structure.
Convergências e divergências românicas. Do Latim "habēre" e "tenēre" às formas contemporâneas no PE, no PB, no Italiano e no Napolitano

Ao tratar de divergências e convergências linguísticas na România, o romanista alemão Harri Meier (1948) defendeu que as evoluções divergentes do latim naRomânia derivariam da divisão dialetal dessa língua já na península Itálica. No que diz respeito às relações linguísticas entre as penínsulas Itálica e Ibérica, o autor sugere que a substituição dos continuadores do verbo latino habēre, em uma partemaior ou menor de suas funções, pelos do verbo tenēre no português e no espanhol teria uma analogia em dialetos da Itália meridional, especialmente nos agrupados sob o rótulo de napolitano. Partindo, pois, dessa hipótese, investigaram-se de forma comparativa os usos dos verbos habēre e tenēre no latim clássico e de seus continuadores nas variedades contemporâneas do português (europeu e brasileiro), do italiano padrão e do napolitano. Essa investigação teve como objetivo identificar possíveis motivações de natureza semântica para as convergências e divergências entre o latim e as variedades neolatinas citadas com relação ao uso dos verbos em questão. A pesquisa foi realizada com base em textos escritos, datados, literários, em prosa e de tipo narrativo.

Published: November 2018

The Bowersox Daugherty (1987) logistics strategy typology (Process Strategy, Market Strategy, and Information Strategy) is an important conceptual framework for studying logistics/supply chain management strategy and its role on logistics/supply chain management outcomes. The purpose of this research is to empirically apply the typology in Peru and compare the findings with the previous research conducted in Guatemala. The three Bowersox/Daugherty dimensions are used to define the construct Overall Logistic Strategy (OLS), and then, the OLS was used to measure Organizational Competitiveness (COMP) through two intervening variables LCE (Logistics Coordination Effectiveness) and CSC (Customer Service Commitment). The results indicate that generally the logistics strategy in Peru is fundamentally similar to Guatemala’s. In other words, the direction of the relationships among the conceptualized constructs tested in the SEM model was significant and explained a sizable variation in COMP in both countries. This provided additional support for the robustness of the structural model in different cultural environments. However, some differences are apparent. First, the importance of the three independent variables and three dependent variables appear to be greater to the Peruvian respondents than Guatemalan respondents. Second, on closer inspection Peruvian logistics data indicates relatively greater emphasis on information, coordination, customer service, and relatively less emphasis on cost efficiency, than Guatemalan managers. Managerial insights and suggestions for future research and discussed.
Identifying critical skills for logistics professionals: Assessing skill importance, capability, and availability

Published: November 2018

The purpose of this research is to identify critical skills needed in the logistics profession now and in the future. This study uses survey research, means tests, and importance analysis to explore a multi-factor framework that identifies critical supply chain skills perceived by 176 experienced supply chain professionals from manufacturing, transportation, and retail/wholesale segments. Results indicate significant differences exist between current and future needed skills, among current capabilities and current availability of skills, and among skill needs utilizing a multi-factor index. Identifying needed skills based on importance is common. Considering more factors than just importance offers a more thorough assessment that reduces potential oversights and inefficiencies that can occur if decision makers focus on one factor when planning key processes, such as recruiting, hiring, and training, in a talent management program.

Este artigo pretende evidenciar as articulações entre a narrativa, a política e a vida social, conferindo especial importância à linguagem ficcional e seu impacto na transposição de dilemas privados à esfera pública de debate.

Para tanto, estruturamos o texto em três partes. A primeira busca recuperar os principais aspectos da teoria da Indústria Cultural, apontando suas insuficiências

em reconhecer a) a capacidade crítica e reflexiva dos públicos com relação aos produtos culturais de massa e b) a potência da forma narrativa para a organização das identidades, das experiências coletivas sociais e das questões políticas. A segunda parte visa apontar a narrativa ficcional - desde

o romance-folhetim até à ficção seriada televisiva - como fonte de elementos que nos auxilia a estruturamos nossa experiência no mundo, ao mesmo tempo em que nos permite conferir sentido à nossa própria história de vida. Na

terceira parte, evidenciamos o papel exercido pela narrativa na constituição de processos de tematização e resolução de problemas na esfera pública.

Um modelo dissonante: caracterização e gêneros do jornalismo literário
Authors: Passos Mateus Yuri , Orlandini Romulo Augusto
Published: November 2018

Teóricos cia Comunicação, Linguagem e Literatura têm abordado obras pertencentes a um agrupamento de gêneros textuais marcados pela hibridização de ambos os campos, a que se tem chamado jornalismo literário ou narrativo, 1) qual constitui um modelo comunicacional paralelo e antagônico aquele Fundamentado na estrutura do lead e piramide invertida.

Neste artigo, discutimos a teoria de gêneros do discurso desenvolvida por Mikhail Bakhtin para classificar textos de jornalislismo literário, levando em consideração as divergências fundamentais que constituem diferentes gêneros

discursivos dentro de uma mesma categoria. A partir do entrecruzamento de definições anteriores, sintetizamos cinco elementos essenciais, a partir dos quais se desdobram procedimentos constitutivos das obras (imersão,

expansão, precisão, subjetivação e experimentação), e listamos seis gêneros básicos (romance_reportagem, biografia, conto-reportagem, perfil, crônica e carta-reportagem), rios quais se originam outros. identificamos também

o surgimento de variantes e novos gêneros, conforme alterações em tema, estrutura de composição e estilo.
(Re)Traçando o armário de celulóide
Authors: Hoff Benedict
Published: November 2018

A discusão do homoerotismo e sua representação no cinema latino-americano

recente muitas vezes tem sido enquadrada por uma preocupação de acentuar a (homo)

ssexualidade latino-americana corno "outra" e, por conseqüencia, uma relutância em situar

tais filmes num cânone homoerótico ou queer internacional, em particular, por causa da sua

suposta falta de "assuntos identitários" ou de narrativas de coming out. Mobilizando um

relato espacial da sexualidade e, conseqüentemente, uma concepção fluída de identidade

sexual, este ensaio propõe um modo de análise mais inclusivo que ultrapasse os limites do

armário para reconhecer tanto a particularidade cultural, quanto a transnacionalidade das

representações encontradas.
O medo como mídia: estratégias de narração no jornalismo de O Globo
Authors: Matheus Leticia
Published: November 2018

Este artigo apresenta o resultado de uma pesquisa que pretendeu evidenciar a

comunicação jornalística como um processo dinàmico que solicita e reconfigura uma memória

das sensações, tendo como elemento principal o medo. Destacou-se o medo como

mediador da experiência cotidiana na cidade do Rio, a partir de narrativas apresentadas

pelo jornal O Globo, na sua cobertura policial. Estudaram-se dois episódios: um assalto a

uma estação do metrô, no qual morreu uma adolescente, e um ataque a uma universidade,

do qual saiu ferida uma aluna, ambos em 2003. As coberturas desses dois casos se deram a

partir de Uni conjunto de estratégias narrativas que forneceram um efeito de continuidade

temporal e espacial ao fenônemo da violência urbana. Deste modo, a leitura que se faz de

cada novo crime se encontra em diálogo com parâmetros interpretativos fornecidos anteriormente

pelo próprio jornal.
Medialidade: encontros entre os estudos literários e os estudos de mídia
Authors: Muller Adalberto , Felinto Erick
Published: November 2018

Este trabalho tem como objetivo fornecer um panorama abrangente dos novos

problemas e campos de estudo compreendidos pela Medientheorie e pela Mediengeschiechte

germânicas. Nesse novo horizonte dos estudos de mídia e da história da mídia, estudos

literários e teoria da comunicação encontram-se em uma preocupação comum com o tema

dos suportes materiais e dos contextos culturais das diferentes mídias (incluído, aí, naturalmente,

os suportes da "mídia" literatura: pergaminho, livro, hipertexto, etc). Através da

discussão de autores como Hans Ulrich Gumbrecht, Friedrich Kittler, Sigfried Ziehnski, e

outros, pretendemos abordar as possibilidades desses campos e teorias para tratar de questões

como a da literariedade face aos novos suportes digitais e das relações entre teorias comunicacionais e teorias literárias.
Narrativa cinematográfica em Lamorisse: O poético, o simbólico, o imaginário
Authors: Rahde Maria Beatriz
Published: November 2018

Esse artigo busca tecer algumas considerações sobre a narrativa do time curta

metragem, Le I3a1/on Rouge (França, 1956), de Albert Larnorisse, que, em apenas trinta minutos

e com mais de cinquenta anos de existência, soube manter o encantamento do imaginário

poético, perpassado por urna linguagem simbólica. A poesia que Lamorisse traduz

na suas imagens narrativas confere urna Impressão visual leve e ao mesmo tempo densa,

ao evocar metaforicamente OS contos infantis, mesclados corri o surreal, pois o roteiro se

torna um poema, traduzido iconográficamente. A simbologia do período modernista é

evidenciada nas cenas silenciosas de linguagem falada, mas intensas na linguagem visual,

em que a música desempenha um papel de destaque O que não é verbalizado é revertido

simbólicamente, tornando visível o invisível. Nessa proposta de técnica narrativa, Larnorisse

evoca diversos elementos componentes do imaginário , corno o sonho, a arte, os mitos,

o fantástico ou a fantasia.
Objetividade e credibilidade midiática: reflexões sobre uma suposta conexão
Authors: Seidenglanz René , Sponholz Liriam
Published: November 2018

As informações transmitidas pela mídia têm credibilidade porque são corretas ou são "corretas" porque acredita-se que sejam? Credibilidade pode ser reduzida a objetividade? Até que ponto existe uma relação entre objetividade e credibilidade e que tipo de relação é esta? Os autores desenvolvem aqui a tese de que credibilidade é determinada por uma série de fatores, dentro da qual a adequação das informações à realidade tem um papel

secundário. Além disso, determinados rituais de objetividade como neutralidade e fairness (o principio de ouvir os dois lados) podem contribuir para dar credibilidade, mas não estão necessariamente ligados à adequação de uma cobertura jornalística à realidade.
CONSUMO SIMBÓLICO DA ESFERA PRODUTIVA DAS MERCADORIAS: Significações de tradição, de memória e de história social
Authors: Casaqui Vander
Published: November 2018

O artigo trata das estratégias da publicidade contemporânea nas representações do mundo do trabalho e da esfera produtiva das mercadorias, como elementos de construção do universo simbólico das marcas. A partir da análise de três comerciais, das marcas Bauducco, Mitsubishi e Johnnie Walker, veiculados recentemente na televisão brasileira, refletimos sobre os processos de mitificação, os apagamentos, as ressemantizações de signos relacionados à produção para compor a visibilidade do trabalho pela lógica do consumo. A metodologia de análise do ethos discursivo organiza a leitura dos filmes publicitários que compõem o estudo.
Ciborgues no ciberespaço: articulações entre potência, tecnologia e apropriação de sentido
Authors: Rodrigues Carla
Published: November 2018

O objetivo desse artigo é discutir as proposições que George Landow faz sobre hipertextualidade, a partir de um diálogo que estabelece com o pensamento de Jacques Derrida. Procuro demonstrar que, em Landow, o hipertexto aparece como instrumento mais potente para se alcançar o sentido de um texto, numa leitura que reforçaria um ideal de potência supostamente presente na articulação humano-máquina. Para isso, tomo como ponto de partida o ciborgue de Donna Haraway para discutir aspectos dessa articulação entre máquina e potência.
REINVENTANDO O AUDIOVISUAL BRASILEIRO: ALGUMAS NOTAS
Authors: Cesário Lia Bahia , Amancio Tunico
Published: November 2018

O artigo tem como proposta investigar as disputas que atravessam o processo de reorganização do campo audiovisual brasileiro diante da tendência mundial da convergência transmidiática. A reflexão se volta prioritariamente para a relação entre cinema e televisão no Brasil nos anos 2000, a partir de exemplos como a criação da Globo Filmes, co-produções da televisão com produtoras independentes e novos marcos regulatórios e mecanismos de incentivos específicos de entrelaçamento entre os meios. Este movimento de reinvenção do campo do audiovisual será historicizado e problematizado a fim de encontrar as singularidades que conformam o campo audiovisual brasileiro diante da convergência transmidiática.
FOTOGRAFIA, CIÊNCIA E MITO Uma interseção estética
Authors: Barros Ana Taís Martins Portanova
Published: November 2018

Passados mais de 170 anos de sua descoberta, a fotografia ainda assombra ciência e senso comum por sua testemunhabilidade, acenando para uma estética profundamente enraizada no tempo vivido. A ciência e, nesse caso especial, a semiologia, vocacionada à desmitologização, fez da fotografia objeto de estudo sob a égide de sua ontologia sígnica em geral, indicial em particular. Paradoxalmente, as tentativas científicas de separar representação de realidade fazem supor o absoluto da realidade fotográfica, retornando ao tempo total do mito, remitologizando o que se queria desmitologizado. Em vez de indicar um erro no procedimento científico, essa recursividade sinaliza a imperatividade da experiência e a presença do illud tempus mesmo no mais racional dos empreendimentos humanos.
Microcelebridades: entre meios digitais e massivos
Authors: Braga Adriana
Published: November 2018

Este artigo busca discutir alguns aspectos do fenômeno a que denominei “microcelebridades” (Braga, 2008), participantes que se celebrizaram no âmbito das redes sociais na Internet. A dispersão do polo da produção midiática promovida pela Comunicação Mediada por Computador (CMC) perece radicalizar a ideia de “recepção ativa”. As microcelebridades são um fenômeno emergente neste universo, e sua crescente popularidade não raras vezes resulta em atuações nos meios de comunicação de massa (MCM). Este artigo busca explorar justamente este ângulo do fenômeno, a interação entre microcelebridades e meios de comunicação de massa, particularmente a televisão, a partir de dois casos emblemáticos: a transposição do conteúdo de um blog para o formato de seriado de tv, e a participação de uma twiteira no programa Big Brother Brasil 10, da Rede Globo.

Cindy Sherman entre-imagens: film stills, gleams and reflection
Authors: Portas Danusa Depes
Published: November 2018

A proposta desse ensaio convida à reflexão sobre as relações que travamos com o tempo e no tempo que chamamos de nosso. Em função disso, o valor de contemporaneidade nele referido pressupõe não simplesmente o pertencimento a um contexto cronologicamente delimitado, mas sim uma operação de leitura que problematize esse pertencimento, esse contexto e seus limites e referências temporais, valendo-se das séries fotográficas da artista visual Cindy Sherman como intercessor.
Cidade, Periferia e Culturas Policentricas
Authors: Villaça Nizia Maria Souza
Published: November 2018

O texto “Cidade, periferia e culturas policentricas” busca por em relevo as novas articulações que se estabelecem entre cultura, corpo e cidade no desenvolvimento dos processos de subjetivação individuais e coletivos. Uma nova semiose se impõe entre emoções e afetos que desalojam a cultura dominante herdeira do iluminismo mobilizando todo um imaginário urbano regido pelos jovens e pela periferia.
