Heavy metal removal from MSS fly ash by thermal and chlorination treatments
Authors: Liu Jingyong , Chen Jiacong , Huang Limao
Published: November 2015

The thermal behavior of heavy metals in the co-incineration of municipal solid waste-sludge incinerator fly ash (MSS fly ash) was studied using a laboratory-scale tube furnace. The results indicate that without the addition of chlorinating agents, temperature was an important parameter and had significantly influenced on heavy metal removal, whereas the residence time had a weak effect. Between 900 and 1000 °C for 60 to 300 min, heavy metals reacted with chloride-inherent in the fly ash and approximately 80 to 89% of Pb, 48% to 56% of Cd, 27% to 36% of Zn and 6% to 24% of Cu were removed. After the adding chlorinating agents, the evaporation rate of the heavy metals improved dramatically, where the evaporation rates of Cu and Zn were larger than that of Pb and Cd. As the amount of added chlorinating agents increased, the removal rate of heavy metals increased. However, the effect of the type of chlorinating agent on the chlorination of heavy metals differed considerably, where NaCl had the weakest effect on the removal rate of Cu, Cd and Zn. In terms of resource recovery and decontamination, MgCl2 and CaCl2 are the best choices due to their efficient removal of Zn.
Lévy Walk Navigation in Complex Networks: A Distinct Relation between Optimal Transport Exponent and Network Dimension
Authors: Weng Tongfeng , Small Michael , Zhang Jie , Hui Pan
Published: November 2015

We investigate, for the first time, navigation on networks with a Lévy walk strategy such that the step probability scales as pij ~ dij–α, where dij is the Manhattan distance between nodes i and j and α is the transport exponent. We find that the optimal transport exponent αopt of such a diffusion process is determined by the fractal dimension df of the underlying network. Specially, we theoretically derive the relation αopt = df + 2 for synthetic networks and we demonstrate that this holds for a number of real-world networks. Interestingly, the relationship we derive is different from previous results for Kleinberg navigation without or with a cost constraint, where the optimal conditions are α = df and α = df + 1, respectively. Our results uncover another general mechanism for how network dimension can precisely govern the efficient diffusion behavior on diverse networks.

Parental influence on begging call structure in zebra finches (Taeniopygia guttata): evidence of early vocal plasticity
Authors: Villain Avelyne S. , Boucaud Ingrid C. A. , Bouchut Colette , Vignal Clémentine
Published: November 2015

Begging calls are signals of need used by young birds to elicit care from adults. Different theoretical frameworks have been proposed to understand this parent–offspring communication. But relationships between parental response and begging intensity, or between begging characteristics and proxies of a young’s need remain puzzling. Few studies have considered the adjustment of nestling begging features to previous experience as a possible explanation of these discrepancies. In this study, we tested the effect of a heterospecific rearing environment on individual developmental trajectories of the acoustic structure of nestling begging calls. Fifty-two zebra finch chicks were fostered either to Bengalese finch or to zebra finch parents, and begging calls were recorded at several stages of nestling development. Acoustic analyses revealed that the development of the spectral features of the begging calls differed between experimental conditions: chicks reared by Bengalese finches produced higher pitched and less broadband begging calls than chicks reared by conspecific parents. Differences were stronger in males than females and were not explained by differences in growth rate. We conclude that nestling begging calls can be plastic in response to social interactions with parents.
A dialogic account of reader–text interactions
Authors: Davis Dennis S. , McElhone Dot , Tenore F. Blake
Published: November 2015

Purpose

– The purpose of this paper is to present a conceptualization of reading comprehension that extends beyond the traditional cognitive viewpoint on comprehension common in the field.

Design/methodology/approach

– Drawing on literature and theory from various perspectives (cognitive, sociocultural and critical), the authors propose a conceptual heuristic that can inform future scholarship.

Findings

– Using four foundational principles of reader–text interactions as a starting point (non-neutrality, tethered polysemy, variable agency and unruliness), the authors describe reader–text interactions in terms of the tethers/resources that are brought into the interaction, the moment-to-moment improvisation that occurs when readers meet a text and the changes at the intra- and interpersonal levels that result from and influence future reader–text interactions.

Originality/value

– The conceptualization can inform future research and practice in literacy by situating meaning making within a broader understanding of the processes and consequences of textual interaction.
Making visible the dance
Authors: Rust Julie
Published: November 2015

Purpose

– This paper aims to delve deeply into the sometimes clashing interplays in English classrooms to explore the ways in which new media makes visible long-existing discourses and assumptions about the purpose of schools and the roles of teachers and students.

Design/methodology/approach

– This piece draws upon discourse analysis and utilizes the frame of strategies versus tactics (de Certeau, 1984) to trace the complex classroom interplays between a high school English teacher, a partnering researcher and a high school junior during the process of a month-long digital photography project.

Findings

– Data reveal that, at times, both teachers and students made moves to preserve the status quo of the school space (through strategies), and at other times, worked to reshape the space for more relevant purposes (through tactics.) Strategies that emerge from teacher moves include the formalization of requirements and the controlling of bodies; the student strategy described is the perpetuation of stereotypes. Teacher tactics reported include repositioning identities, reframing “the work” and opening up space for inquiry. Student tactics include resistance, shifting to the personal, subverting a given task and self-positioning. The author argues that generative potential exists at the intersection of teacher tactics and student tactics, and calls for furthering the co-construction of classroom spaces.

Originality/value

– By zooming in on the process, rather than the product, that ensued as the focal student created and defended her photographs representing school as jail, this paper emphasizes the agency that both teachers and students can enact in sometimes limiting classroom spaces.
The enemy of my enemy is my friend … or still my enemy
Authors: Weaver John Michael
Published: November 2015

Purpose

– World events underscore political challenges. Even with the relaxation of import/export impediments, the continuance of market globalization, the reduction of travel restriction among many countries combined with challenges throughout the globe that exist, the world appears to becoming an increasingly dangerous place. Heads of government and leaders throughout public sector organizations must have situational awareness of what is going on, not just within their own national boundaries, but what is taking place in the contiguous countries to their own and beyond. Decisions made regarding one issue could have profound secondary and tertiary effects on the situation abroad. This is particularly true when looking at countries as a primary unit of analysis in the context of international relations. The paper aims to discuss these issues.

Design/methodology/approach

– A qualitative research methodology was used focussing on secondary data.

Findings

– A public sector leader’s decisions can have a profound impact beyond that of one’s specific agency. When senior government leaders make decisions, they must consider the impact beyond that of their own organization.

Research limitations/implications

– This paper focussed solely on secondary research sources.

Practical implications

– This paper has implications for senior government leaders and military officers alike.

Social implications

– When a leader makes a decision, he or she should look at the secondary and tertiary effects of their decisions so as to push for an utilitarian approach when solving problems.

Originality/value

– The author believe that this is an original paper focussing on contemporary world events.
Bullous pemphigoid: What's ahead?
Authors: Furue Masutaka , Kadono Takafumi
Published: November 2015

Bullous pemphigoid (BP) is an autoimmune subepidermal blistering skin disease mainly affecting older individuals. Pathogenic autoantibodies preferentially target the non‐collagenous 16A domain of collagen XVII (also called BP antigen 2, BPAG2) present in hemidesmosomes. The pathogenic anti‐BPAG2 antibodies cause the dermal–epidermal separation in neonatal and adult mice as well as in cryosections of human skin. These experimental BP models stress a pivotal role for neutrophils and the Fcγ receptor of immunoglobulins. Mice that have been genetically manipulated in the pathogenic domain of BPAG2 spontaneously develop subepidermal blistering with pruritus and eosinophilic infiltration. BPAG2 is physiologically and aberrantly expressed in neuronal tissue and internal malignancies, and the associations of BP with Parkinson's disease, stroke and internal malignancies invites new investigations into the immunological dysregulation behind the comorbidity.
Assessing Low Redox Stability of Myoglobin Relative to Rapid Hemin Loss from Hemoglobin
Authors: Cai He , Tatiyaborworntham Nantawat , Yin Jie , Richards Mark P.
Published: November 2015

Bovine myoglobin (Mb) auto‐oxidized 11‐fold faster at pH 5.7 compared to bovine hemoglobin (Hb). Replacement of Ser(F7) in bovine Mb with positively charged or large apolar residues decreased auto‐oxidation rates (2‐ to 4‐fold) in comparison with wild‐type Mb (P < 0.05). However, the same substitutions increased hemin loss rate (15‐ to 28‐fold), indicating that hydrogen bonding between Ser(F7) and the heme‐7‐propionate is critical for stabilizing protoporphyrin in the globin. The anchoring of Ser(F7) to the heme‐7‐propionate in the proximal pocket of Mb is suggested to expose the distal pocket to solvent molecules that accelerate auto‐oxidation. The rate of hemin loss from metHb at pH 5.7 was 68‐fold faster compared to metMb. The ability of Ser(F7) and His(FG3) in Mb to form stabilizing contacts with the heme‐7‐propionate maintains hemin within the globin whereas Leu(F7) and Leu(FG3) of Hb cannot form stabilizing contacts which results in low hemin affinity. MetHb promoted lipid oxidation more effectively in washed muscle at pH 5.7 compared to metMb (P < 0.05). The greater ability of bovine metHb to promote lipid oxidation is likely due to its enhanced rate of hemin dissociation compared to bovine metMb.
Irinotecan plus fluorouracil‐based regimen as second or third‐line chemotherapy for recurrent or metastatic esophageal squamous cell carcinoma
Authors: Wang Xi , Wang Xinwei , Huang Jing
Published: November 2015

Background

No standard second‐line regimen exists for the treatment of advanced esophageal squamous cell carcinoma (ESCC). The aim of this study was to evaluate the efficacy and safety of irinotecan and fluorouracil‐based chemotherapy as a second or third‐line regimen for advanced ESCC patients.

Methods

We retrospectively reviewed a cohort of 27 consecutive patients with advanced ESCC in one institute, treated with a combination of irinotecan plus fluorouracil‐based regimens after the failure of first‐line platinum‐based therapy. Nine patients were treated with 150–160 mg/m2 irinotecan and 400 mg/m2 fluorouracil (5‐FU) on day 1, followed by 2000 mg/m2 5‐FU during a 48‐hour infusion every two weeks. Eighteen patients received 150–160 mg/m2 irinotecan on day 1 and 80–120 mg/day S‐1 on days 1–10 every two weeks. The S‐1 dose was based on the patients' body surface area.

Results

Twenty‐four of the 27 patients were assessable for response. One (3.7%) patient achieved complete response, seven (25.9%) achieved partial response, eight (29.6%) had stable disease, and eight (29.6%) had progressive disease. The median progression‐free and overall survival were 4.8 (95% confidence interval [CI]: 1.2–8.4) and 10.5 months (95% CI: 8.4–12.7), respectively. Grade 3 neutropenia and diarrhea were detected in four (15%) and one (4%) patient, respectively. No grade 4 toxicity was noted.

Conclusions

Our study indicates that an irinotecan plus 5‐FU‐based regimen is effective and well‐tolerated as a second or third‐line chemotherapy for patients with advanced ESCC.
The Company You Keep: How Voters Infer Party Positions on European Integration from Governing Coalition Arrangements
Authors: Adams James , Ezrow Lawrence , Wlezien Christopher
Published: November 2015

Recent studies document that voters infer parties’ left‐right positions from governing coalition arrangements. We show that citizens extend this coalition‐based heuristic to the European integration dimension and, furthermore, that citizens’ coalition‐based inferences on this issue conflict with alternative measures of party positions derived from election manifestos and expert placements. We also show that citizens’ perceptions of party positions on Europe matter, in that they drive substantial partisan sorting in the electorate. Our findings have implications for parties’ election strategies and for mass‐elite policy linkages.
Pre‐diabetes tsunami: incidence rates and risk factors of pre‐diabetes and its different phenotypes over 9 years of follow‐up
Authors: Hadaegh F. , Derakhshan A. , Zafari N. , Khalili D. , Mirbolouk M. , Saadat N. , Azizi F.
Published: November 2015

Aims

To investigate the incidence of pre‐diabetes and its different phenotypes and the related risk factors during 9 years of follow‐up.

Methods

A total of 5879 people (2597 men and 3282 women) aged ≥ 20 years, free of diabetes and pre‐diabetes, took part in the study. Multivariable Cox proportional hazard models were used to evaluate hazard ratios (HR) and 95% confidence intervals (CI) for all potential risk factors.

Results

Overall, 853 men and 902 women developed pre‐diabetes. Incidence rates of pre‐diabetes were 46.1 per 1000 person‐years in men and 36.8 per 1000 person‐years in women, while isolated impaired fasting glucose had the highest incidence rate among all pre‐diabetes phenotypes. In both sexes, age, family history of diabetes, fasting plasma glucose and 2–hour post‐challenge plasma glucose were related to incident pre‐diabetes. Among women, waist‐to‐height ratio [HR: 1.02 (1.00–1.03)] and being divorced/widowed compared with married [HR: 0.67 (0.52–0.87)] were significant predictors of pre‐diabetes; whereas among men, community‐based intervention [HR: 0.79 (0.68–0.90)], higher level of education and being single [HR: 0.77 (0.6–0.97)] were protective against progression to pre‐diabetes. Moreover, hip circumference among women [HR: 0.95 (0.93–0.98)] and current smoking among men [HR: 1.69 (1.15–2.48)] were related to incident combined impaired fasting glucose and impaired glucose tolerance.

Conclusion

More than 4% of the Iranian population develop pre‐diabetes each year, emphasizing the important role of socio‐economic factors (marital status, education and smoking habits) and community‐based intervention in progression to impaired glucose regulations. Thus, emergent intervention is necessary to halt the tsunami of pre‐diabetes among the Iranian population.
Recessive mutations in the cancer gene Ataxia Telangiectasia Mutated (ATM), at a locus previously associated with metformin response, cause dysglycaemia and insulin resistance
Authors: Connelly P. J. , Smith N. , Chadwick R. , Exley A. R. , Shneerson J. M. , Pearson E. R.
Published: November 2015

Aim

To investigate glucose and insulin metabolism in participants with ataxia telangiectasia in the absence of a diagnosis of diabetes.

Methods

A standard oral glucose tolerance test was performed in participants with ataxia telangiectasia (n = 10) and in a control cohort (n = 10). Serial glucose and insulin measurements were taken to permit cohort comparisons of glucose‐insulin homeostasis and indices of insulin secretion and sensitivity.

Results

During the oral glucose tolerance test, the 2‐h glucose (6.75 vs 4.93 mmol/l; P = 0.029), insulin concentrations (285.6 vs 148.5 pmol/l; P = 0.043), incremental area under the curve for glucose (314 vs 161 mmol/l/min; P = 0.036) and incremental area under the curve for insulin (37,720 vs 18,080 pmol/l/min; P = 0.03) were higher in participants with ataxia telangiectasia than in the controls. There were no significant differences between groups in fasting glucose, insulin concentrations or insulinogenic index measurement (0.94 vs 0.95; P = 0.95). The Matsuda index, reflecting whole‐body insulin sensitivity, was lower in participants with ataxia telangiectasia (5.96 vs 11.03; P = 0.019) than in control subjects.

Conclusions

Mutations in Ataxia Telangiectasia Mutated (ATM) that cause ataxia telangiectasia are associated with elevated glycaemia and low insulin sensitivity in participants without diabetes. This indicates a role of ATM in glucose and insulin metabolic pathways.
Asynchronous hatching provides females with a means for increasing male care but incurs a cost by reducing offspring fitness
Authors: Ford L. E. , Smiseth P. T.
Published: November 2015

In species with biparental care, sexual conflict occurs because the benefit of care depends on the total amount of care provided by the two parents while the cost of care depends on each parent's own contribution. Asynchronous hatching may play a role in mediating the resolution of this conflict over parental care. The sexual conflict hypothesis for the evolution of asynchronous hatching suggests that females adjust hatching patterns in order to increase male parental effort relative to female effort. We tested this hypothesis in the burying beetle Nicrophorus vespilloides by setting up experimental broods with three different hatching patterns: synchronous, asynchronous and highly asynchronous broods. As predicted, we found that males provided care for longer in asynchronous broods whereas the opposite was true of females. However, we did not find any benefit to females of reducing their duration of care in terms of increased lifespan or reduced mass loss during breeding. We found substantial negative effects of hatching asynchrony on offspring fitness as larval mass was lower and fewer larvae survived to dispersal in highly asynchronous broods compared to synchronous or asynchronous broods. Our results suggest that, even though females can increase male parental effort by hatching their broods more asynchronously, females pay a substantial cost from doing so in terms of reducing offspring growth and survival. Thus, females should be under selection to produce a hatching pattern that provides the best possible trade‐off between the benefits of increased male parental effort and the costs due to reduced offspring fitness.
Physical Activity Levels of Non-overweight, Overweight, and Obese Children During Physical Education
Authors: Pathare Neeti , Piche Kelly , Nicosia Andrea , Haskvitz Esther
Published: November 2015

Purpose:

The purpose of this study was to examine physical activity (PA) levels of young children classified by body mass index (BMI) (nonoverweight, overweight, and obese) during physical education classes.

Method:

Participants included 82 children (45 boys, 37 girls; 7.5 ± 1.2 years). PA was determined by the number of steps measured with pedometers. Data were analyzed with a three-way ANOVA (BMI × grade × gender).

Results:

No interaction was observed. There was a significant main effect for BMI. Children in the nonoverweight group took more steps than the children in overweight and obese groups during physical education classes.

Discussion/Conclusion:

The findings suggest that differences existed in PA during physical education classes in young children dependent on their BMI.
Effect of iron supplementation on psychomotor development of non-anaemic, exclusively or predominantly breastfed infants: a randomised, controlled trial
Authors: Chmielewska Anna , Chmielewski Grzegorz , Domellöf Magnus , Lewandowski Zbigniew , Szajewska Hania
Published: November 2015

Introduction

Uncertainty exists regarding the effects of iron supplementation during infancy on neurodevelopmental outcomes in the absence of anaemia. The aim of the study is to establish whether psychomotor and mental development is influenced by early iron supplementation in healthy, non-anaemic, exclusively or predominantly breastfed infants.

Methods and analysis

Healthy term infants will be recruited. If exclusively or predominantly breast fed (>50% of daily feedings) and not anaemic at 4 months, they will be randomised to receive either iron pyrophosphate (approximately 1 mg/kg) or placebo daily until 9 months of age. The primary outcome measure is neurodevelopment assessed with the Bayley Scales of Infant and Toddler Development (Bayley-III) at 12 months, and repeated at 24 and 36 months of age. Haematological parameters of iron metabolism also will be measured.

Ethics and dissemination

The Bioethics Committee of the Medical University of Warsaw approved the study protocol before recruitment started. Study results will be submitted to peer-reviewed journals in the fields of paediatrics and nutrition, and presented at relevant conferences.

Les mécanismes de formation du limbe chez le Manihot esculenta : étude microchirurgicale
Authors: Médard R.
Published: November 2015

Inside the distal part of a leaf primordium approximately 12 cells thick and differentiated into distinct abaxial and adaxial areas, the following events occur simultaneously, at an early critical stage, in the middle of the second plastochron of leaf development: (i) determination of the differentiation of the two layers of cells bordering the abaxial–adaxial contact area into palisade and spongy parenchyma; (ii) determination of the ability of these two tissues to react to a triggering of mitotic activity, which enables them to initiate the lamina formation; (iii) determination of the formation, between the two tissues, of a system that inhibits dorsiventral mitosis and constitutes the foundation for lamina development. From the fifth plastochron, this threefold control system will lead to the organogenesis of the lamina. Depending on the stage of development, two kinds of anomalies occur on the lamina when the abaxial–adaxial contact area is disturbed. Disturbance during the early critical stage results in organoid enations and later disturbance in light and dark spots. These anomalies are comparable to those resulting from severe virus infections. The above process of development is not compatible with the classical model of lamina development.
Microwave irradiation for rapid killing and fixing of plant tissue

Published: November 2015

Irradiation by microwaves allows for rapid killing and fixing of plant tissue, with excellent cellular integrity for histological examination. Two exposures to microwaves for 3 s in formalin – acetic acid – alcohol gave good preservation of nuclei, chloroplasts, and other plant structures. The microwave method offers a considerable saving of time over traditional methods for killing and fixing plant tissue.
Stochastic SIS metapopulation models for the spread of disease among species in a fragmented landscape
Authors: Ekanayake Amy J.
Published: November 2015

Two stochastic models are derived for a susceptible–infectious–susceptible epidemic spreading through a metapopulation: a continuous time Markov chain (CTMC) model and an Itô stochastic differential equation (SDE) model. The stochastic models are numerically compared. Close agreement suggests that computationally intense CTMC simulations can be approximated by simpler SDE simulations. Differential equations for the moments of the SDE probability distribution are also derived, the steady states are solved numerically using a moment closure technique, and these results are compared to simulations. The moment closure technique only coarsely approximates simulation results. The effect of model parameters on stability of the disease-free equilibrium is also numerically investigated.
Adverse Effects of Wheat Gluten
Authors: Koning Frits
Published: November 2015

Man began to consume cereals approximately 10,000 years ago when hunter-gatherers settled in the fertile golden crescent in the Middle East. Gluten has been an integral part of the Western type of diet ever since, and wheat consumption is also common in the Middle East, parts of India and China as well as Australia and Africa. In fact, the food supply in the world heavily depends on the availability of cereal-based food products, with wheat being one of the largest crops in the world. Part of this is due to the unique properties of wheat gluten, which has a high nutritional value and is crucial for the preparation of high-quality dough. In the last 10 years, however, wheat and gluten have received much negative attention. Many believe that it is inherently bad for our health and try to avoid consumption of gluten-containing cereals; a gluten-low lifestyle so to speak. This is fueled by a series of popular publications like Wheat Belly; Lose the Wheat, Lose the Weight, and Find Your Path Back to Health. However, in reality, there is only one condition where gluten is definitively the culprit: celiac disease (CD), affecting approximately 1% of the population in the Western world. Here, I describe the complexity of the cereals from which gluten is derived, the special properties of gluten which make it so widely used in the food industry, the basis for its toxicity in CD patients and the potential for the development of safe gluten and alternatives to the gluten-free diet.

Poder e liturgia em The Godfather de Francis Ford Coppola
Authors: Fidalgo António
Published: November 2015

O filme "The Godfather" (intitulado "O padrinho", em Portugal, e "O poderoso chefão", no Brasil) é um filme de "gangsters", de uma família mafiosa, de um poder constituído fora da lei. A conquista, a manutenção e a defesa do poder é feita com recurso à violência, ao assassinato inclusive. A tese que proponho expor e defender neste artigo é que o poder da família Corleone não é um poder despótico, mas um poder altamente controlado, regulamentado por códigos de honra, de parentesco, de amizade. Isso por um lado, e por outro lado, que o exercício desse poder tem uma componente simbólica fortíssima, uma componente litúrgica como irei demonstrar.

Sintoma de nossos tempos: representações do ideal adolescente em matérias sobre parricídio
Authors: Duccini Mariana
Published: November 2015

Este artigo pretende analisar, em duas reportagens publicadas pela revista semanal de informação Época, no ano de 2002, de que maneira as estratificações sociais, em terminologia de S. Moscovici, respaldam a construção de representações sociais tangentes a um crime de parricídio, mobilizando configurações imaginárias que dizem respeito, sobretudo, a um ideal de adolescência típico de nossos tempos. Considerando-se uma característica inerente à dinâmica dos discursos, qual seja, a de falar em nome de uma vontade de verdade que traduz articulações de um jogo de poder – o poder de instalar significados socialmente aceitos –, o estudo tentará depreender de que maneira tais vontades de verdade se materializam, em um discurso midiático, estabelecendo parâmetros de legitimação relativos às práticas e condutas sociais.

Nossas principais referências são Muniz Sodré, Kabengele Munanga, Frantz Fanon e Homi Bhabha.
Linguagem cinematográfica como inscrição da marginalidade na produção de documentários brasileiros pós-1993
Authors: Souza Gustavo
Published: November 2015

A presença dos setores sociais vinculados diretamente ao contexto de marginalidade e violência urbana tem sido recorrente na produção de documentários brasileiros dos últimos anos. Entender este movimento requer voltarmos as atenções não apenas para os depoimentos que tratem do contexto social, econômico e urbano dos grandes centros brasileiros, mas também para o uso da linguagem cinematográfica como um recurso que materializa a condição marginal dos depoentes. Tal aspecto revela a importância do diálogo com outros gêneros audiovisuais para a apreensão desses elementos, que posteriormente revelarão uma possível “estética da marginalidade”.
O documentário e seu público
Authors: Trindade Teresa Noll
Published: November 2015

O crescimento da produção e a valorização do documentário nacional é algo bastante reconhecido nos dias de hoje e os motivos para isso são múltiplos. Porém, a “euforia” por essa conquista pode fazer esquecer um lado dessa história que é referente ao baixo número de espectadores que esses filmes atraem. Pode-se argumentar que esta não é uma questão exclusiva do documentário, mas do cinema nacional como um todo. Este artigo se propõe a analisar este tema: o documentário e seu público. A dinâmica do texto
consiste em abordar o problema através de dados estatísticos, realizando uma classificação temática do documentário e discutindo em que medida podemos relacionar a variação de público com a escolha de determinados assuntos.
Coelhos na cartola: publicidade e entretenimento na campanha de Sony Bravia
Authors: Furtado Juliana De Assis
Published: November 2015

Na publicidade contemporânea, observamos um movimento de certas campanhas para uma direção que exclui a racionalidade. O produto surge desmaterializado, caracterizado por sensações, sons e idéias visuais que, em conjunto, transmitem seu benefício de uma forma intangível. Em muitos casos, ele apenas assina a peça, aliado à força de um conceito que centraliza suas qualidades. O imperativo é ausente, e a persuasão fica por conta de uma imagem de marca pré-construída, que concentra valores invisíveis – mas já cravados no imaginário do público a que se destina. O lúdico toma conta da mensagem, tornando-se a ponte que separa (ou une) publicidade e entretenimento. É o caso da campanha publicitária da TV Sony
Bravia, que há alguns anos tem seus filmes premiados em festivais pelo mundo. Neste trabalho, analisamos o mais recente deles, ouro em Cannes no ano de 2008. Como acontece a desmaterialização? Pelo que o produto é substituído? Que valores essa construção veicula? São perguntas que buscamos responder.

Kraftwerk e a ausência dos corpos Notas sobre um show no Rio de Janeiro em 2004 (e outro em 2009)
Authors: Castanheira José Cláudio Siqueira
Published: November 2015

Este artigo procura pensar a virtualização dos corpos na cultura contemporânea através de três eixos principais. O primeiro seria o de como o som e a imagem são separados de sua materialidade através de novas técnicas de construção audiovisual. Usando um show da banda alemã Kraftwerk como exemplo, demonstro como a música eletrônica passou a se valer de um objeto sonoro desvinculado de um corpo empírico, o que pode ser estendido para a produção de imagens de síntese. Num segundo momento trato de como os corpos são virtualizados por essas tecnologias. Esse tipo de pensamento vai resultar em construções sócio-tecnológicas como os conceitos de Inteligência Artificial e de Ciborgues. Por fim tento mostrar como o mundo real, em suas diversas instâncias, desde a econômica até a cultural, tende a virtualizar-se, opondo a experiência descorporificada à materialidade.

Padrões, formato e a expectativa de uma linguagem natural nas mídias digitais
Authors: Ranoya Guilherme
Published: November 2015

Este artigo é produto dos debates realizados ao longo do curso “Pensadores do ciberespaço”, conduzido pela professora doutora Elizabeth Saad no programa de Pós-Graduação em Ciências da Comunicação da Universidade de São Paulo em 2010, e faz parte da tese de doutorado, em andamento, O intuitivo nas mídias interativas, orientada pelo professor doutor Mauro Wilton de Sousa, abordando uma visão sobre o conceito de intuitividade com base nos autores que discutem o problema da forma, ou suas forças determinantes, como parte elementar de uma linguagem e de uma relação entre o homem e os objetos.
O mundo da infância e a infância no mundo: vozes de crianças nas revistas brasileiras Veja e Época
Authors: Doretto Juliana , Costa Renata
Published: November 2015

A infância não deve ser estudada a partir da questão de “qual é o mundo da criança”, porque o mundo delas é o mesmo dos adultos. Assim, não é possível haver um “ponto de vista sobre o mundo da criança”. Na verdade, ela mesma (assim como todos nós) é um “ponto de vista sobre o mundo”. Com Foucault, poderíamos dizer que ser capaz de ocupar um ponto de vista é uma potência do discurso. Potência essa que a criança não detém, como mostra análise de textos sobre a infância publicados em 2011 nas duas maiores revistas semanais brasileiras, Veja e Época.
Indústria da música ou indústria do disco? A questão dos suportes e de sua desmaterialização no meio musical
Authors: Vicente Eduardo
Published: November 2015

A intenção deste texto é oferecer um relato acerca do desenvolvimento histórico da indústria fonográfica a partir da perspectiva dos seus suportes de distribuição. Ele parte da premissa de que a questão dos suportes é fundamental para a compreensão tanto de muitas das características assumidas pela indústria ao longo de sua história— como a concentração econômica, a sua vinculação às editoras musicais e a relação entre hardware e software — quanto de sua crise atual.
Entre o medo de ser só mais um e a exigência de ser si mesmo: distinção e autenticidade na propaganda brasileira dos anos 1970 e 2000
Authors: Mazetti Henrique
Published: November 2015

Este artigo analisa e compara os anúncios publicitários brasileiros veiculados nas décadas de 1970 e 2000 com o intuito de descobrir quais foram as transformações ocorridas nos modelos de subjetividade apresentados pela propaganda entre os dois períodos. As evidências empíricas apontam a predominância, nos anúncios dos anos 1970, de incentivos para que os indivíduos se compreendam e se relacionem com os outros através da busca por distinção e status social. Já nos anos 2000, identifica-se a ascensão de apelos relativos à autenticidade, produtos e marcas prometem auxiliar os indivíduos a serem si mesmos. Além de demonstrar como os ideais de distinção e autenticidade são elaborados na publicidade, busca-se compreender o que tornou possível a assimilação do discurso da autenticidade pela propaganda.
Entrevista no telejornalismo: configurações históricas da vigilância em programas de entrevista
Authors: Silva Fernanda Mauricio da
Published: November 2015

A entrevista é um formato do jornalismo constantemente associado a valores como interesse público, vigilância e objetividade. Na televisão, ela parece assumir contornos ainda mais evidentes de qualidade de apuração e busca por uma informação mais aprofundada. O presente artigo pretende demonstrar que essas concepções são construídas historicamente a partir de uma relação entre o telejornalismo e a cultura. Sendo assim, propomos uma breve análise sobre o modo como a entrevista foi se legitimando no telejornalismo e incorporando seus valores, especialmente o de vigilância. Para isso, assumimos que o telejornalismo é uma forma cultural e que as formas de fazer entrevista se articulam fortemente com o contexto cultural que a insere. Ao final, apresentamos alguns caminhos metodológicos para a análise do telejornalismo.
Crônica de um verão e Jogo de cena: tecendo outros cotidianos
Authors: Silva Míriam Cristina Carlos
Published: November 2015

Este artigo analisa o documentário como um processo experimental de linguagem, no qual o cotidiano é explicitado para servir como possibilidade de reflexão e crítica. Discute-se o recorte realizado pelo diretor, que se torna também narrador: aquele que ouve e realiza a mediação da experiência relatada por seus entrevistados. A partir das aproximações entre Crônica de um verão, de Jean Rouch, e Jogo de cena, de Eduardo Coutinho, fica demonstrada a possibilidade da prática destes documentaristas como um método de pesquisa, ou melhor, como metáporo – na proposição de Marcondes – do qual se pode extrair, também, um conceito de comunicação.

Zumbis no cinema brasileiro: uma abordagem paracinemática
Authors: Carreiro Rodrigo
Published: November 2015

Um dos monstros mais populares do imaginário do cinema de horror internacional desde a década de 1930, o zumbi demorou a aparecer no cinema brasileiro, e tem permanecido uma figura marginal nos filmes produzidos no país. Amparado pelo conceito de paracinema, cunhado por Jeffrey Sconce, este ensaio procura traçar um panorama da presença do zumbi em longas-metragens nacionais e propor uma leitura política que permita explicar essa marginalidade.

A partir de dois ensaios, intitulados “Quelle émotion! Quelle émotion?” e “Uma foto familiar: aprisco de emoções e pensamentos [anotações delirantes sobre (a)sombrografia]”, assinados respectivamente por Georges Didi-Huberman e Eduardo Peñuela Cañizal, o artigo desenvolve uma reflexão sobre a história das artes visuais, a natureza das imagens, os modos de interpretá-las e a busca das emoções humanas em seus modos expressivos e artísticos. Ao fazê-lo, convida o leitor a ficar atento ao que cada um desses autores diz dos “gestos”, do trabalho do “inconsciente” e da “imaginação”, das dimensões – heurística e poética – dos “arquivos da memória” humana.
Flora da Serra do Cipó, Minas Gerais: Celastraceae Sensu Lato
Authors: Groppo Milton , Erbert Cíntia
Published: November 2015

O estudo da família Celastraceae é parte do levantamento da “Flora da Serra do Cipó”, Minas Gerais, Brasil. Em sua delimitação mais recente, as Celastraceae sensu lato englobam as Hippocrateaceae, já tratadas em levantamento anterior para a Serra Cipó, esta última com três gêneros (Cheiloclinium, Peritassa e Tontelea) e quatro espécies. A estes gêneros e espécies de Hippocrateceae são somadas agora as espécies de Celastraceae sensu stricto, com o gênero Maytenus (sete espécies) e Plenckia, com uma espécie, além de duas espécies de dois gêneros (Pristimera e Salacia) das tradicionais Hippocrateaceae coletadas após a publicação do levantamento. Com isso, para a Serra do Cipó são registrados sete gêneros e 14 espécies de Celastraceae sensu lato. São apresentadas chaves para os gêneros e espécies de Celastraceae sensu lato e descrições e ilustrações das Celastraceae sensu stricto (não tratadas anteriormente), além de comentários sobre sua distribuição geográfica, fenologia e variabilidade. Comentários e uma lista atualizada de exsicatas das “Hippocrateaceae” são também apresentados. Adicionalmente, é proposta a sinonímia de Maytenus salicifolia Reissek sob Maytenus gonoclada Mart.
Polygonatum campanulatum (Asparagaceae), a new species from Yunnan, China
Authors: XIU-ZHEN CAI , GUANG-WAN HU , ELIZABETH MWIHAKI KAMANDE , VERONICAH MUTELE NGUMBAU , NENG WEI
Published: November 2015

Polygonatum Miller (1754: without pagination) is characterized by thick fleshy creeping sympodial rhizomes with elongated aerial stem and fleshy berries (Tamura et al. 1997). This genus contains 60 or more species in the world and widely distributed in the warm-temperate to boreal zones of the Northern Hemisphere with five species in Europe and three species in North America and concentrated (about 50 species) in East Asia (from Russia and Japan to Himalaya) (Tang 1978, Conran & Tamura 1998, Chen & Tamura 2000, Utech 2002, Judd 2003, Ohara et al. 2007). Chen & Tamura (2000) recognized 39 species for China, 20 of them being endemic to the country (see also Tang 1978). Since then, Floden (2014) and Zhao & He (2014) described two new taxa, both from Yunnan, China.
