Espaços alternativos na internet como formas de visibilizar as mulheres no jornalismo brasileiro

Despite the feminization of journalistic newsrooms in Latin America, the Global Report on the Status of Women in the News Media (2015) indicates that the top professional status in those places is still male, which leads to a lower likelihood of women writing stories, or being it’s characters; the same report also demonstrates Vtha the percentage of women as a source of information is still low. The process reproduces the persistent patriarchal vision and is part of the so-called women «invisibility» in the media. This work assumes that also in Brazil, the feminization process of the editorial staff does not come along with any content that values the woman, although there are advances. The text presents five digital journalism experiments that seek to fill the gap of traditional coverage on women’s issues, treating woman as an autonomous social actor. The structure of these initiatives was examined and their content, during the period July/August of 2016, have been analysed to verify how the woman appears as a social protagonist. This work allowed a reflection on how the «new journalism» can overcome stereotypes, inducing the visibility and the social empowerment of women. It is concluded that the analyzed initiatives can be considered points of observation to integrate positive practices in hegemonic journalism, expanding the democratic and egalitarian use of the media.
SEP performance of coherent MPSK over fading channels in the presence of phase/quadrature error and I-Q gain mismatch

This letter presents a joint approach to the symbol-error probability (SEP) of coherent M-ary phase-shift keying in a situation where the phase error, quadrature error, and in-phase-quadrature (I-Q) gain mismatch problems take place all concurrently over an additive white Gaussian noise and arbitrary fading channel. A set of equations that characterizes the conditional SEP on an instantaneous fading signal-to-noise ratio is derived in the form of the Craig representation.
An approach to deriving roughness length and zero-plane displacement height from satellite data , prototyped with BOREAS data

Global climate models typically use relatively crude estimates of roughness length, often based on constant values for land cover category. However, large variations may exist within any of the vegetation categories. Global large-scale estimates of roughness length, such as required by climate models, cannot rely on field experiments for practical reasons and must, therefore, be derived from satellite observations. This paper develops a satellite retrieval method for the roughness parameters, momentum roughness length, zo, and displacement height, d. The formulas, based on the observational data of Raupach [Raupach, M.R. , 1992. Bound. -Layer Meteor. 60, 375–395; Raupach, M.R. , 1994. Bound. -Layer Meteor. 71, 211–216] and Lindroth [Lindroth, A. , 1993. Bound. -Layer Meteor. 66, 265–272], are applicable to most types of vegetation. Raupach relates the momentum roughness length and zero-plane displacement height to the frontal area index, λ, and to the height of the vegetation,h. The frontal area index is related to the shape of an average tree or plant crown and to the average density of the canopy elements. The crown shape factor includes the aspect (height-to-width) ratio of the crown and the geometric shape of the crown. Lindroth relates the momentum roughness length to the leaf area index (LAI) and to the height of the trees. The functional form ofzo/h is peaked in both frontal area index, with the maximum occurring at λ=0.152, and average plant LAI (Lp), with the maximum occurring at Lp=0.878. Asλ andLp increase, d/h also increases and approaches an upper limit asymptotically at high values of λ andLp. As the vegetation height is difficult to obtain from present satellite data, retrievals are restricted to fractional values (i.e. zo/h andd/h) for global application. This retrieval then requires data for the crown aspect ratio, the canopy density (fractional overstory canopy cover) and the LAI. Data from BOREAS ( BORealEcosystemAtmosphereStudy) are used to illustrate this satellite retrieval method. © 2000 Elsevier Science B.V. All rights reserved.
A Fuzzy Multi-Metric QoS-Balancing Gateway Selection Algorithm in a Clustered VANET to LTE Advanced Hybrid Cellular Network

Intelligent transportation systems are currently attracting the attention of the research community and the automotive industry, which both aim to provide not only more safety in the transportation systems but other high-quality services and applications for their customers as well. In this paper, we propose a cooperative traffic transmission algorithm in a joint vehicular ad hoc network-Long Term Evolution Advanced (LTE Advanced) hybrid network architecture that elects a gateway to connect the source vehicle to the LTE Advanced infrastructure under the scope of vehicle-to-infrastructure (V2I) communications. The originality of the proposed fuzzy quality-of-service (QoS)-balancing gateway selection (FQGwS) algorithm is the consideration of QoS traffic class constraints for electing the gateway. Our algorithm is a multicriteria and QoS-based scheme optimized by performing the fuzzy logic to make the decision on the appropriate gateway. Criteria are related to the received signal strength (RSS) and load of the cluster head (CH) and gateway candidates (GwCs), as well as the vehicle-to-vehicle link connectivity duration (LCD). Simulation results demonstrate that our algorithm gets better results than the deterministic scheme for gateway selection. Moreover, results show the efficiency of the FQGwS algorithm as it adapts its gateway selection decision to the cluster density and the relative velocity of the source node.
Minimizing the number of detectors in poll-based link failure detection and identification

Link failure is one of the most critical network fault conditions. Relying solely on SNMP traps to detect and identify link failures is not a complete solution. To supplement the SNMP-trap mechanism, one or more detectors can be placed in the network to periodically poll the devices using the ping or traceroute utilities such that all links are under the surveillance of the detectors. The goal is to place the smallest number of detectors to have all of the links under surveillance such that the cost of placing detectors in the network is reduced. In this paper, this problem is formulated as a minimum set covering problem. A new heuristic algorithm is proposed for this problem. Simulations are performed to study the performance of the proposed heuristic algorithm.
Branched Polyamines Cure Prion-Infected Neuroblastoma Cells

ABSTRACT Branched polyamines, including polyamidoamine and polypropyleneimine (PPI) dendrimers, are able to purge PrPSc, the disease-causing isoform of the prion protein, from scrapie-infected neuroblastoma (ScN2a) cells in culture (S. Supattapone, H.-O. B. Nguyen, F. E. Cohen, S. B. Prusiner, and M. R. Scott, Proc. Natl. Acad. Sci. USA 96:14529–14534, 1999). We now demonstrate that exposure of ScN2a cells to 3 μg of PPI generation 4.0/ml for 4 weeks not only reduced PrPSc to a level undetectable by Western blot but also eradicated prion infectivity as determined by a bioassay in mice. Exposure of purified RML prions to branched polyamines in vitro disaggregated the prion rods, reduced the β-sheet content of PrP 27-30, and rendered PrP 27-30 susceptible to proteolysis. The susceptibility of PrPSc to proteolytic digestion induced by branched polyamines in vitro was strain dependent. Notably, PrPSc from bovine spongiform encephalopathy-infected brain was susceptible to PPI-mediated denaturation in vitro, whereas PrPSc from natural sheep scrapie-infected brain was resistant. Fluorescein-labeled PPI accumulated specifically in lysosomes, suggesting that branched polyamines act within this acidic compartment to mediate PrPSc clearance. Branched polyamines are the first class of compounds shown to cure prion infection in living cells and may prove useful as therapeutic, disinfecting, and strain-typing reagents for prion diseases.
Disruption of the gene encoding p12 (SecG) reveals the direct involvement and important function of SecG in the protein translocation of Escherichia coli at low temperature.

The Escherichia coli cytoplasmic membrane protein, p12, stimulates the protein translocation activity reconstituted with SecY, SecE and SecA. The gene encoding p12, which is located at 69 min on the E. coli chromosome, was deleted to examine the role of p12 in protein translocation in vivo. The deletion strain exhibited cold‐sensitive growth. Pulse‐chase experiments revealed that precursors of outer membrane protein A, maltose binding protein and beta‐lactamase accumulated at 20 degrees C but not at 37 degrees C. The deletion strain harboring a plasmid which carries the gene encoding p12 under the control of the araBAD promoter was able to grow in the cold when p12 was expressed with the addition of arabinose. Furthermore, the accumulated precursors were rapidly processed to the mature forms upon the expression of p12. Immunoblot analysis revealed the steady‐state accumulation of precursor proteins at 20 degrees C, whereas the accumulation was only marginal at 37 degrees C, indicating that the function of p12 is more critical at 20 degrees C than at 37 degrees C. Finally, proteoliposomes were reconstituted with or without p12 to demonstrate that the stimulation of the activity by p12 increases with a decrease in temperature. From these results, we concluded that p12 is directly involved in protein translocation in E. coli and plays a critical role in the cold. We propose the more systematic name, SecG, for p12.
Haptoglobin 1-1 Genotype Modulates the Association of Glycemic Control With Hippocampal Volume in Elderly Individuals With Type 2 Diabetes

Recent evidence suggests that glycemic control is associated with cognitive function in older patients with type 2 diabetes who are carriers of the haptoglobin (Hp) 1-1 genotype compared with noncarriers. We assessed whether poor glycemic control in Hp 1-1 carriers is more strongly associated with smaller hippocampal volume than in noncarriers. Hippocampal volume was generated from high-resolution structural T1 MRI obtained for 224 participants (28 Hp 1-1 carriers [12.5%] and 196 noncarriers [87.5%]) from the Israel Diabetes and Cognitive Decline (IDCD) study, who had a mean (SD) number of years in the Maccabi Healthcare Services (MHS) registry of 8.35 (2.63) and a mean (SD) HbA1c level of 6.66 (0.73)% [49 mmol/mol]. A stronger negative association between right hippocampal volume and HbA1c was found in patients with the Hp 1-1 genotype, with a 0.032-mL decrease in right hippocampal volume per 14% increase in HbA1c (P = 0.0007) versus a 0.009-mL decrease in Hp 1-1 noncarriers (P = 0.047), after adjusting for total intracranial volume, age, sex, follow-up years in the registry, and cardiovascular factor (interaction, P = 0.025). This indicates that 29.66% of the total variance in right hippocampal volume is explained by HbA1c levels among Hp 1-1 carriers and that 3.22% is explained by HbA1c levels among Hp 1-1 noncarriers. Our results suggest that the hippocampus of Hp 1-1 carriers may be more vulnerable to the insults of poor glycemic control.
Indoor Localization Algorithm Based on Cooperative of State Matrix and Kalman Filter

Wireless location is a key technology for wireless sensor networks (WSN). This paper firstly describes a wireless location system based on nanoLOC chip which can provide both high-accuracy location and data communication. Secondly, we present an indoor location algorithm based on cooperative of state matrix and Kalman filter (State-LKalman), and apply it to the time of arrival(TOA) algorithm of the wireless location system. Simulation results show that the State-LKalman has high accuracy than the cooperative of least square error (LSE) and Kalman filter (LKalman) algorithm. Finally, we describe the design of the hardware and software of the system and do the experiments on the platform. Experimental results show that the system is stable and reliable and can achieve high accuracy location; the cumulative probability of 1.5 meter error can achieve 50%.
Effect of Piracetam on ECT-Induced Cognitive Disturbances: A Randomized, Placebo-Controlled, Double-Blind Study

Electroconvulsive therapy (ECT) is still the fastest, most effective, and frequently life-saving therapeutic intervention in several forms of depression and some other psychiatric disorders. Transient memory disturbances are frequent after ECT. A randomized, double-blind, placebo-controlled study was conducted to investigate the effects of piracetam on ECT-induced confusion and memory disturbances. Thirty-eight consecutively admitted patients with depressive illness or schizophrenia requiring ECT were given either piracetam or an identical-looking placebo during the period of ECT treatment and for 2 weeks afterward. Daily dosage of piracetam was 7.2 g, given orally for the first 2 weeks while patients underwent ECT (loading phase), followed by 4.8 g for the rest of the study period. Participants were evaluated by standardized clinical rating scales and cognitive psychologic tests 1 to 2 days before ECT, 1 day after their third and sixth ECT treatments, and 2 weeks after they had completed their ECT courses. Piracetam had no significant effect in preventing ECT-induced memory disturbances. All clinical ratings were consistently, albeit not significantly, better in the piracetam group, suggesting that piracetam may have augmented the effects of ECT.
Differences in Social Decision-Making between Proposers and Responders during the Ultimatum Game: An EEG Study

The Ultimatum Game (UG) is a typical paradigm to investigate social decision-making. Although the behavior of humans in this task is already well established, the underlying brain processes remain poorly understood. Previous investigations using event-related potentials (ERPs) revealed three major components related to cognitive processes in participants engaged in the responder condition, the early ERP component P2, the feedback-related negativity (FRN) and a late positive wave (late positive component, LPC). However, the comparison of the ERP waveforms between the responder and proposer conditions has never been studied. Therefore, to investigate condition-related electrophysiological changes, we applied the UG paradigm and compared parameters of the P2, LPC and FRN components in twenty healthy participants. For the responder condition, we found a significantly decreased amplitude and delayed latency for the P2 component, whereas the mean amplitudes of the LPC and FRN increased compared to the proposer condition. Additionally, the proposer condition elicited an early component consisting of a negative deflection around 190 ms, in the upward slope of the P2, probably as a result of early conflict-related processing. Using independent component analysis (ICA), we extracted one functional component time-locked to this deflection, and with source reconstruction (LAURA) we found the anterior cingulate cortex (ACC) as one of the underlying sources. Overall, our findings indicate that intensity and time-course of neuronal systems engaged in the decision-making processes diverge between both UG conditions, suggesting differential cognitive processes. Understanding the electrophysiological bases of decision-making and social interactions in controls could be useful to further detect which steps are impaired in psychiatric patients in their ability to attribute mental states (such as beliefs, intents, or desires) to oneself and others. This ability is called mentalizing (also known as theory of mind).
A Path Querying Language for Federation of RDF and Relational Database

In this paper, we present a federated path querying language (FPQ) as itself an extension of the nested regular path querying language with adding an axis operator to support the federation of RDF dataset and relational database. We have proven that FPQ has more expressive power than the nested regular path query language (not to mention regular path querying language). It enjoys the same computational complexity as the regular path query language and its additional expressivity can be exactly used to characterize the conjunction and federation of nested regular path queries. Moreover, we discuss the expressivity of various fragments of FPQ and implement FPQ. Finally, we present an application scenario related to the car-pooling services in real life.

We theoretically find a bandwidth of 4 µm can be generated using four-wave mixing and soliton self-frequency shift in an As<inf>2</inf>Se<inf>3</inf>-based chalcogenide PCF with an air-hole-diameter-to-pitch ratio of 0.4 and a pitch of 3 µm.
Entrepreneurial Discovery and the Competitive Market Process: An Austrian Approach

Modern Austrian Economics, building on earlier work of Mises and Hayek, explains the determination of market prices in terms of entrepreneurial discovery processes. Dissatisfied with mainstream equilibrium models, Austrians see market equilibrating tendencies as series of competitive discoveries increasing mutual awareness among market participants. (Unlike deliberate search, discovery consists in alert entrepreneurs noticing profit opportunities, generated by earlier errors, which had been entirely unsuspected.) This approach entails unconventional implications for such issues as: antitrust policy, economic justice under capitalism, the meaning of economic welfare, and the possibility of rational planning under socialism.
Comparison of Differential evolution and Cuckoo optimization for antenna array problems

We present comparison of Differential evolution and Cuckoo search for optimization of linear antenna array of Hertzian dipoles. The amplitudes of excitations are optimized in order to minimize sidelobe levels. The results are compared for 42 elements array, with 20 optimization variables. The conclusion is that classic Differential evolution provides better convergence for this particular problem than standard Cuckoo search.
L 2 writing teachers ’ perspectives , practices and problems regarding error feedback Icy Lee ∗

While research on error correction has focused a great deal on whether teachers should correct errors in student writing and how they should go about it, teacher beliefs and perceptions regarding error feedback have received relatively little attention. This study investigated L2 writing teachers’ perspectives, practices and problems regarding error feedback. A questionnaire was administered to 206 secondary English teachers in Hong Kong and follow-up telephone interviews were conducted with 19 of them. The questionnaire consisted of both open and close-ended questions, asking teachers about how they correct student errors in writing, how they perceive their work in error correction, as well as their concerns and problems. The follow-up interviews, which were semi-structured, provided in-depth information about salient aspects of the questionnaire findings. The results of the study show that although selective marking is recommended both in the local English syllabus and error correction literature, the majority of teachers mark errors comprehensively. Teachers tend to treat error feedback as a job with little long-term significance. Although they are spending a massive amount of time marking student writing, teachers themselves are not totally convinced that their effort pays off in terms of student improvement. The paper ends with a discussion of the implications that arise from the study. © 2003 Elsevier Inc. All rights reserved.
Perfusion reduction at transcatheter intraarterial perfusion MR imaging: a promising intraprocedural biomarker to predict transplant-free survival during chemoembolization of hepatocellular carcinoma.

PURPOSE To investigate the predictive value of transcatheter intraarterial perfusion (TRIP) magnetic resonance (MR) imaging-measured tumor perfusion changes during transarterial chemoembolization on transplant-free survival (TFS) in patients with unresectable hepatocellular carcinoma (HCC). MATERIALS AND METHODS This HIPAA-compliant prospective study was approved by the institutional review board. Written informed consent was obtained from all patients. Fifty-one consecutive adult patients with surgically unresectable single or multifocal measurable HCC and adequate laboratory parameters who underwent chemoembolization in a combined MR imaging-interventional radiology suite between February 2006 and June 2010 were studied. Tumor perfusion changes during chemoembolization were measured by using TRIP MR imaging with area under the time-signal intensity curve calculation. The end point of the study was TFS. The authors assessed the correlation between the percentage perfusion reduction in the tumor during chemoembolization and TFS by using univariate and multivariate analyses. RESULTS Fifty patients (mean age, 61 years; 39 men aged 42-87 years [mean age, 61 years] and 11 women aged 49-83 years [mean age, 62 years]) were eligible for the analysis. Patients with 35%-85% intraprocedural tumor area under the time-signal intensity curve reduction (n = 32) showed significantly improved median TFS compared with patients with an area under the time-signal intensity curve reduction outside this range (n = 18) (16.6 months [95% confidence interval: 11.2, 22.0 months] vs 9.3 months [95% confidence interval: 6.6, 12.0 months], respectively; P = .046; hazard ratio: 0.46; 95% confidence interval: 0.21, 1.00). The cumulative TFS rates in the 35%-85% and less than 35% or more than 85% perfusion reduction groups at 1, 2, and 5 years after chemoembolization were 66.4%, 42.2%, and 28.2% versus 33.8%, 16.9%, and 0%, respectively. CONCLUSION The study shows evidence of an association between intraprocedural tumor perfusion reduction during chemoembolization and TFS and suggests the utility of TRIP MR imaging- measured tumor perfusion reduction as an intraprocedural imaging biomarker during chemoembolization.
Physiological origins of evoked magnetic fields and extracellular field potentials produced by guinea‐pig CA3 hippocampal slices

This study examined whether evoked magnetic fields and intra‐ and extracellular potentials from longitudinal CA3 slices of guinea‐pig can be interpreted within a single theoretical framework that incorporates ligand‐ and voltage‐sensitive conductances in the dendrites and soma of the pyramidal cells. The 1991 CA3 mathematical model of R. D. Traub is modified to take into account the asymmetric branching patterns of the apical and basal dendrites of the pyramidal cells. The revised model accounts for the magnitude and waveform of the bi‐ and triphasic magnetic fields evoked by somatic and apical stimulations, respectively, in the slice in the absence of fast inhibition (blocked by 0.1 mm picrotoxin). The revised model also accounts for selective effects of 4‐aminopyridine (4‐AP) and tetraethylammonium (TEA), which block the potassium channels of A and C type, respectively, on the slow wave of the magnetic fields. Furthermore, the model correctly predicts the laminar profiles of field potential as well as intracellular potentials in the pyramidal cells produced by two classes of cells ‐ those directly activated and those indirectly (synaptically) activated by the applied external stimulus. The intracellular potentials in this validated model reveal that the spikes and slow waves of the magnetic fields are generated in or near the soma and apical dendrites, respectively. These results demonstrate that a single theoretical framework couched within the modern concepts of cellular physiology provides a unified account of magnetic fields outside the slice, extracellular potentials within the slice and intracellular potentials of the pyramidal cells for CA3.
