Já Gramsci, colaborou de forma decisiva para reconceitualizar a questão, historicizando-a e associando-a integralmente a um movimento político (hegemônico). Apesar da clara limitação do número de autores discutidos, pode-se argumentar que os problemas e soluções colocadas por Marx e Gramsci atravessam o debate marxista em geral, permitindo, por isso, vislumbrar alguns dilemas e possibilidades centrais dados à problemática no campo.</span></span></span></p><p class="MsoNormal" style="margin: 0cm 0cm 0pt;"><span style="mso-bidi-font-size: 10.0pt;"><span style="font-size: x-small; font-family: Times New Roman;"> </span></span></p><p class="MsoNormalCxSpFirst" style="line-height: 150%; text-align: justify;"> </p></span>

Advertisement–programme congruence in memory of sexual fragrance advertisements
Authors: Wong Hiu Yan Amy , McClelland Alastair , Furnham Adrian 
Published: January 2019

SummaryThe current study explored the effect of sexual content in advertisements and the programme–advertisement congruence on the memory of sexual and nonsexual advertisements. Seventy participants (41 females and 29 males) were randomly allocated to one of four conditions. They viewed either The Bachelorette (sexual programme) or I'm a Celebrity… Get Me Out of Here! (nonsexual programme) with sexual or nonsexual fragrance advertisements placed within the programme. The order of the advertisements was counterbalanced across participants to control for order effects. Free and cued recall of the advertisements were assessed. As predicted, there was a main effect of advertisement type, with the sexual advertisements better recalled than the nonsexual advertisements. Contrary to our prediction, the sexual content of the programme did not have an effect on advertisement recall. There was an interaction between the advertisement type and programme type; sexual advertisements were remembered better when embedded within a sexual programme. Limitations of this study are considered.

Published: January 2019

AbstractThe wide clinical application of photodynamic therapy (PDT) is hampered by poor water solubility, low tumor selectivity, and nonspecific activation of photosensitizers, as well as tumor hypoxia which is common for most solid tumors. To overcome these limitations, tumor‐targeting, redox‐activatable, and oxygen self‐enriched theranostic nanoparticles are developed by synthesizing chlorin e6 (Ce6) conjugated hyaluronic acid (HA) with reducible disulfide bonds (HSC) and encapsulating perfluorohexane (PFH) within the nanoparticles (PFH@HSC). The fluorescence and phototoxicity of PFH@HSC nanoparticles are greatly inhibited by a self‐quenching effect in an aqueous environment. However, after accumulating in tumors through passive and active tumor‐targeting, PFH@HSC appear to be activated from “OFF” to “ON” in photoactivity by the redox‐responsive destruction of the vehicle's structure. In addition, PFH@HSC can load oxygen within lungs during blood circulation, and the oxygen dissolved in PFH is slowly released and diffuses over the entire tumor, finally resulting in remarkable tumor hypoxia relief and enhancement of PDT efficacy by generating more singlet oxygen. Taking advantage of the excellent imaging performance of Ce6, the tumor accumulation of PFH@HSC can be monitored by fluorescent and photoacoustic imaging after intravenous administration into tumor‐bearing mice. This PFH@HSC nanoparticle might have good potential for dual imaging‐guided PDT in hypoxic solid tumor treatment.

Published: January 2019

AbstractSelf‐assembled RNA particles have been exploited widely to maximize the therapeutic potential of RNA. However, the immune response via RNA particles is not fully understood. In addition, the investigation of the immunogenicity from RNA‐based particles is required owing to inherent immunostimulatory effects of RNA for clinical translation. To examine the immune stimulating potency, rationally designed microsized RNA particles, called RNA microspheres (RMSs), are generated with single or double strands via rolling circle transcription. The RMSs show an exceptional stability in the presence of serum, while they are selectively degraded under endolysosomal conditions. With precisely controlled size, both RMSs are successfully taken up by macrophages. Unlike the nature of RNA fragments, RMSs induce only basal‐level expression of inflammatory cytokines as well as type I interferon from macrophages, suggesting that RMSs are immunocompatible in the therapeutic dose range. Taken together, this study could help accelerate clinical translation and broaden the applicability of the self‐assembled RNA‐based particles without being limited by their potential immunotoxicity, while a systematic controllability study observing the release of RNA fragments from RMSs would provide self‐assembled RNA‐based structures with a great potential for immunomodulation.

Published: January 2019

AbstractThe development of artificial chiral architectures, especially chiral inorganic nanostructures, has greatly promoted research into chirality in nanoscience. The nanoscale chirality of artificial chiral nanostructures offers many new application opportunities, including chiral catalysis, asymmetric synthesis, chiral biosensing, and others that may not be allowed by natural chiral molecules. Herein, the progress achieved during the past decade in chirality‐associated biological applications (biosensing, biolabeling, and bioimaging) combined with individual chiral nanostructures (such as chiral semiconductor nanoparticles and chiral metal nanoparticles) or chiral assemblies is discussed.

Published: January 2019

AbstractElectrochemical energy storage by making H2 an energy carrier from water splitting relies on four elementary reactions, i.e., the hydrogen evolution reaction (HER), hydrogen oxidation reaction (HOR), oxygen evolution reaction (OER), and oxygen reduction reaction (ORR). Herein, the central objective is to recommend systematic protocols for activity measurements of these four reactions and benchmark activities for comparison, which is critical to facilitate the research and development of catalysts with high activity and stability. Details for the electrochemical cell setup, measurements, and data analysis used to quantify the kinetics of the HER, HOR, OER, and ORR in acidic and basic solutions are provided, and examples of state‐of‐the‐art specific and mass activity of catalysts to date are given. First, the experimental setup is discussed to provide common guidelines for these reactions, including the cell design, reference electrode selection, counter electrode concerns, and working electrode preparation. Second, experimental protocols, including data collection and processing such as ohmic‐ and background‐correction and catalyst surface area estimation, and practice for testing and comparing different classes of catalysts are recommended. Lastly, the specific and mass activity activities of some state‐of‐the‐art catalysts are benchmarked to facilitate the comparison of catalyst activity for these four reactions across different laboratories.

Published: January 2019

AbstractRecently, upconversion luminescence (UCL) has been widely applied in bioimaging due to its low autofluorescence and high contrast. However, a relatively high power density is still needed in conventional UCL bioimaging. In the present study, an ultralow power density light, as low as 0.06 mW cm−2, is applied as an excitation source for UCL bioimaging with PbS/CdS/ZnS quantum dots (UCL‐QDs) as probes. The speculated UCL mechanism is a phonon‐assisted single‐photon process, and the relative quantum yield is up to 4.6%. As determined by continuous irradiation with a 980 nm laser, the UCL‐QDs show excellent photostability. Furthermore, UCL‐QDs‐based probe is applied in tumor, blood vessel, and lymph node bioimaging excited with an eye‐safe low‐power light‐emitting diode light in a nude mouse with few heat effects.

Published: January 2019

AbstractHere, high power flexible Schottky barrier diodes (SBDs) are demonstrated on a plastic substrate using single crystalline β‐Ga2O3 nanomembranes (NMs). In order to realize flexible high power β‐Ga2O3 SBDs, sub‐micron thick freestanding β‐Ga2O3 NMs are created from a bulk β‐Ga2O3 substrate and transfer‐printed onto the plastic substrate via a microtransfer printing method. It is revealed that the material property of β‐Ga2O3 NMs such as crystal structure, electron affinity, and bandgap remains unchanged compared with its bulk properties. Flexible β‐Ga2O3 SBDs exhibit the record high critical breakdown field strength (Ec) of 1.2 MV cm−1 in the flat condition and 1.07 MV cm−1 of Ec under the bending condition. Overall, flexible β‐Ga2O3 SBDs offer great promise for future flexible energy convergence systems and are expected to provide a much larger and more versatile platform to address a broader range of high‐performance flexible applications.

Published: January 2019

AbstractUltrathin crystalline silicon (c‐Si) solar cells provide advantages in reducing the use of c‐Si material and being flexible, but there are several challenges that need to be conquered, such as limited optical absorption, high sensitivity to surface recombination, and complicated fabrication issues. Here, all‐solution‐processed Si nanopyramids (SiNPs) are proposed as the surface texture for ultrathin c‐Si solar cells to solve the light absorption issue, whose preparation process is simple, low‐cost, and industrially compatible. Combining the SiNPs texture with good passivation technique, an efficiency of 15.1% with an open circuit voltage approaching 700 mV is realized on a 37 µm thick c‐Si solar cell. Moreover, both experimental and simulation investigation reveal that the SiNP‐textured ultrathin solar cells have quasi‐omnidirectional light absorption characteristic, showing a potential to produce higher all‐day output power compared with the Si micropyramids textured counterpart. To further reduce the cost of ultrathin c‐Si solar cells, a direct copper metallization is also investigated in replacement of silver metallization, which can result in a comparable efficiency. The present work demonstrates the conventional industrial processes for achieving low‐cost ultrathin c‐Si solar cells.

Carbon‐bridged Oligo(phenylenevinylene)s as Light‐harvesting Antenna for Porphyrins

Published: January 2019

AbstractThe efficacy of carbon‐bridged oligo(phenylenevinylenes)s (COPVs) as light‐harvesting antenna for porphyrins is demonstrated using a series of 5,15‐di‐COPVn‐substituted free‐base and zinc porphyrins, COPVn‐MP‐COPVn (n=1–3, M=H2, Zn). These molecules were synthesized by Suzuki–Miyaura cross‐coupling reactions of COPVn‐Bpin and Br‐H2P‐Br. The absorption spectra of these compounds in solution show a significant expansion of the Soret band region together with a bathochromic shift of the Q band, suggesting a significant interaction between these chromophores in the ground state. The photoluminescence quantum yield of the porphyrin‐COPV conjugates is enhanced up to four times relative to the parent porphyrins. Theoretical calculations also indicated interactions between these chromophores in the HOMO, which suggests that the light‐harvesting ability stems from the expansion of the π‐electron‐conjugation system.

Authors: de Araújo Elias Tiago , Costa Mendes Paulo Renato , Elias Normey‐Rico Júlio 
Published: January 2019

AbstractThis paper presents a control algorithm for reducing heat losses caused by clouds in large solar fields. The formulation is based on a Mixed Logical Dynamical (MLD) representation of the solar field plus the application of a Practical Nonlinear Model Predictive Controller (PNMPC) for calculating the optimal control action. The main purpose of the controller is to deactivate fields with inlet temperature greater than outlet temperature and to manipulate the oil flow rate of the activated fields for tracking the reference of the outlet temperature. A simplified lumped parameters model is used for prediction and simulation of the solar fields.
Fault‐tolerant path‐following control for in‐wheel‐motor‐driven autonomous ground vehicles with differential steering

Published: January 2019

AbstractOver the past several decades, the automobile industry has denoted significant research efforts to developing in‐wheel‐motor‐driven autonomous ground vehicles (IWM‐AGVs) with active front‐wheel steering. One of the most fundamental issues for IWM‐AGVs is path following, which is important for automated driving to ensure that the vehicle can track a target‐planned path during local navigation. However, the path‐following task may fail if the system experiences a stuck fault in the active front‐wheel steering. In this paper, a fault‐tolerant control (FTC) strategy is presented for the path following of IWM‐AGVs in the presence of a stuck fault in the active front‐wheel steering. For this purpose, differential steering is used to generate differential torque between the left and right wheels in IWM‐AGVs, and an adaptive triple‐step control approach is applied to realize coordinated lateral and longitudinal path‐following maneuvering. The parameter uncertainties for the cornering stiffness and external disturbances are considered to make the vehicles robust to different driving environments. The effectiveness of the proposed scheme is evaluated with a high‐fidelity and full‐car model based on the veDYNA‐Simulink joint platform.
Necessary conditions of fractional optimal control problems with state constraints in the sense of Riemann‐Liouville
Authors: Ma Linjie , Liu Bin 
Published: January 2019

AbstractThis paper is devoted to the optimal control problem of a fractional dynamic system with state constraints in the sense of Riemann‐Liouville. By means of the needle variation, we establish the Pontryagin's maximum principle for the optimal control problem. Moreover, when such a necessary condition is singular in some sense, we investigate the “second‐order” necessary conditions accordingly. As an application, two examples are presented to demonstrate the accuracy and efficiency of the result.
V@R representation theorems in ambiguous frameworks
Authors: Balbás Alejandro , Charron Jean‐Philippe 
Published: January 2019

AbstractThe value at risk (V@R) is a very important risk measure with significant applications in finance (risk management, pricing, hedging, portfolio theory, etc), insurance (premium principles, optimal reinsurance, etc), production, marketing (newsvendor problem), etc. It also plays a critical role in regulation about risk (Basel, Solvency, etc), it is very appreciated by practitioners due to its intuitive interpretation, and it is the unique popular risk measure remaining finite for heavy tailed risks with unbounded expectation. Besides, ambiguous frameworks are becoming more and more usual in applications of risk analysis. Lack of data or committed errors may provoke discrepancies between real probabilities and estimated ones. This paper combines both V@R and ambiguous settings, and a new representation theorem for V@R is given. Consequently, inspired by previous studies dealing with coherent risk measures and their representation, we will give new methods to compute and optimize V@R under ambiguity. This seems to be a relevant finding because the analytical properties of V@R are very weak if one compares with a coherent risk measure. Indeed, V@R is neither continuous nor convex, which makes it very complicated to deal with it in mathematical approaches. Nevertheless, the results of this paper will allow us to transform computation and optimization problems involving V@R into continuous and differentiable problems.
