Published: December 2021

The firing parameters in ceramic masses incorporated with 0, 5, and 10 wt% of scheelite tailings were investigated. The ceramic masses were characterized by X-ray fluorescence, granulometric, mineralogical analysis, and Atterberg limits determination. The samples were obtained by uniaxial pressing (20 MPa), sintered at different temperatures (800, 900, and 1000 °C), and heating rates (5, 10, 15, and 20 °C∙min−1). Physical and mechanical tests (water absorption, apparent porosity, and flexural strength) and mineralogical tests were accomplished from the sintered samples. Natural aging tests were also carried out to assess carbonation resistance. For this, some samples were kept in an internal environment (inside the laboratory) for 3 months. The results showed a high content of calcium oxide in the scheelite tailings and a reduction in the plasticity index of the ceramic masses with the tailings addition. The best results were observed for the ceramic mass with 5% tailings. The best results were observed regarding the firing parameters for the temperature equal to 1000 °C, increasing the heating rate to 10 °C∙min−1 without compromising the material properties. The samples kept in an internal environment for 3 months showed a loss of physical and mechanical properties. Such behavior probably occurred due to the onset of the carbonation phenomenon.

Authors: Hemmati Mahboobeh , Messadi Tahar , Gu Hongmei
Published: December 2021

Cross-laminated timber (CLT) used in the U.S. is mainly imported from abroad. In the existing literature, however, there are data on domestic transportation, but little understanding exists about the environmental impacts from the CLT import. Most studies use travel distances to the site based on domestic supply origins. The new Adohi Hall building at the University of Arkansas campus, Fayetteville, AR, presents the opportunity to address the multimodal transportation with overseas origin, and to use real data gathered from transporters and manufacturers. The comparison targets the environmental impacts of CLT from an overseas transportation route (Austria-Fayetteville, AR) to two other local transportation lines. The global warming potential (GWP) impact, from various transportation systems, constitutes the assessment metric. The findings demonstrate that transportation by water results in the least greenhouse gas (GHG) emission compared with freight transportation by rail and road. Transportation by rail is the second most efficient, and by road the least environmentally efficient. On the other hand, the comparison of the life cycle assessment (LCA) tools, SimaPro (Ecoinvent database) and Tally (GaBi database), used in this research, indicate a remarkable difference in GWP characterization impact factors per tonne.km (tkm), primarily due to the different database used by each software.
No Net Loss: A Cultural Reading of Environmental Assessment
Authors: Puig Jordi , Villarroya Ana , Casas María
Published: December 2021

Global environmental quality decline builds up through innumerable decisions at many scales that cause damage to ecological and social values. Environmental assessment (EA) is a relevant decision-making framework in this sense. Besides its technical role, EA has a cultural side we should consider in the pursuit of sustainable societies. Despite its limited reach, EA exemplifies and confronts some cultural implicit stances that may unwittingly favor the overall decline of environmental quality, and limit the advancement and efficiency of EA. Many of these cultural traits are well known and easier to point to than to reverse, namely: (1) too tolerant-to-damage standards of environmental protection and equality; (2) inadequate criteria to assess environmental performance; (3) tolerance of the net loss of environmental quality; (4) confrontation between ecological and social values in decision-making; and (5) neglect of full, in-kind compensation of environmental impacts. EA may have not only a technical or procedural, but also a cultural role to play in confronting these sources of unsustainability. A lack of attention to the cultural causes of environmental impacts neglects the deepest roots of environmental damage. This commentary addresses the topics above and brings attention to their disregard for environmental values, which should guide EA towards increased levels of sustainability.

Authors: Lin Kuan-Nan , Chen Chiu-Wen , Chen Chih-Feng , Lim Yee Cheng , Kao Chih-Ming , Dong Cheng-Di
Published: December 2021

The Fengshan River system is one of the major rivers in Kaohsiung City, Taiwan. This study investigated the concentration of eight phthalate esters (PAEs) in sediments of the river and the impact of potential ecological risks during the dry and wet seasons. The potential risk assessment of sediment PAEs was evaluated by adopting the total risk quotient (TRQ) method. The total PAEs concentrations (∑PAEs) in the sediments of the Fengshan River system are between 490–40,190 ng/g dw, with an average of 8418 ± 11,812 ng/g dw. Diisononyl phthalate (38.1%), bis(2-ethylhexyl) phthalate (36.9%) and di-isodecyl phthalate (24.3%) accounted for more than 99.3% of ∑PAEs. The concentration of ∑PAEs in sediments at the river channel stations is higher during the wet season (616–15,281 ng/g dw) than that during the dry season (490–1535 ng/g dw). However, in the downstream and estuary stations, the wet season (3975–6768 ng/g dw) is lower than the dry season (20,216–40,190 ng/g dw). The PAEs in sediments of the Fengshan River may have low to moderate potential risks to aquatic organisms. The TQR of PAEs in sediments at the downstream and estuary (TQR = 0.13) is higher than that in the upstream (TQR = 0.04). In addition, during the wet season, rainfall transported a large amount of land-sourced PAEs to rivers, leading to increased PAEs concentration and potential ecological risks in the upper reaches of the river.

Published: December 2021

The article presents the research results of anaerobic digestion processes in bioreactors of composite mixtures based on initial and residual biomass of Lemna minor duckweed and additives: inoculum (manure), food waste, and spent sorbents to determine biogas potential (biogas volume, methane content). Duckweed Lemna minor, which is widespread in freshwater reservoirs, is one of the promising aquatic vegetation species for energy use. Residual biomass is obtained by chemically extracting valuable components from the primary product. The purpose of the research was to evaluate the possibility of the energy potential of residual biomass of Lemna minor to reduce the consumption of fossil fuels and reduce greenhouse gas emissions. This is in line with the International Energy Agency (IEA) scenarios for the reduction of environmental impact. The obtained results confirm the feasibility of using this type of waste for biogas/biomethane production. The recommendations on the optimal composition of the mixture based on the residual biomass of Lemna minor, which will allow for an increase in biogas production, are given. The obtained data can be used in the design of bioreactors.

Published: December 2021

In the U.S., approximately 9.3 million lead service lines (LSLs) account for most lead contamination of drinking water. As the commitment to replace LSLs with safer materials grows, empirical evidence is needed to understand which households are benefitting most from current replacement practices. This exploratory study analyzes factors predictive of whether an LSL was replaced fully (from water main to premise) or partially (only the portion on public property). Conventional ordinary least squares, negative binomial, and geographically weighted regression models are used to test the hypothesis that full lead service line replacements (LSLRs) were less common in lower-income, higher-minority neighborhoods under a cost-sharing program design in Washington, D.C. between 2009 and 2018. The study finds supportive evidence that household income is a major predictor of full replacement prevalence, with race also showing significance in some analyses. These findings highlight the need for further research into patterns of full versus partial LSLR across the U.S. and may inform future decisions about LSLR policy and program design.

Published: December 2021

Online professional communities based on sharing under open licenses have become a new way of building knowledge, learning and professional development of the participants who build and expand their professional identity in the new global space. These new dynamics of cyberculture are not being sufficiently explored in the training of vocational students. However, open pedagogy models can foster pre-professional identity, influence academic success and self-perception, as well as contribute to the commons. In this study, we have investigated from the anthropological perspective, the impact of a training program based on an open pedagogy model. Specifically, we have investigated the effect on the pre-professional identity and the academic results of vocational students, as well as on the development of the commons of their profession. Methodologically, we have combined the bibliographic review with the empirical, quantitative, and qualitative data, collected in the ethnographic fieldwork carried out during two academic years on 77 students of “Microcomputer Systems and Networks”, in a vocational center located in the Community of Valencia (Spain). The results indicate that this methodology promotes, among students, the development of pre-professional identity, a better understanding of copyright and open licenses, appreciation of the documentation processes of their tasks, and the value of their works for society.
Review on Performance Enhancement of Photovoltaic/Thermal–Thermoelectric Generator Systems with Nanofluid Cooling
Authors: Garud Kunal Sandip , Hwang Seong-Guk , Han Jeong-Woo , Lee Moo-Yeon
Published: December 2021

Photovoltaics (PVs) are an effective technology to harvest the solar energy and satisfy the increasing global electricity demand. The effectiveness and life span of PVs could be enhanced by enabling effective thermal management. The conversion efficiency and surface temperature of PVs have an inverse relationship, and hence the cooling of PVs as an emerging body of work needs to have attention paid to it. The integration of a thermoelectric generator (TEG) to PVs is one of the widely applied thermal management techniques to improve the performance of PVs as well as combined systems. The TEG utilizes the waste heat of PVs and generate the additional electric power output. The nanofluid enables superior thermal properties compared to that of conventional cooling fluids, and therefore the performance of photovoltaic/thermal–thermoelectric generator (PV/T-TEG) systems with nanofluid cooling is further enhanced compared to that of conventional cooling. The TEG enables a symmetrical temperature difference with a hot side due to the heat from PVs, and a cold side due to the nanofluid cooling. Therefore, the symmetrical thermal management system, by integrating the PV/T, TEG, and nanofluid cooling, has been widely adopted in recent times. The present review comprehensively summarizes various experimental, numerical, and theoretical research works conducted on PV/T-TEG systems with nanofluid cooling. The research studies on PV/T-TEG systems with nanofluid cooling were reviewed, focusing on the time span of 2015–2021. This review elaborates the various approaches and advancement in techniques adopted to enhance the performance of PV/T-TEG systems with nanofluid cooling. The application of TEG with nanofluid cooling in the thermal management of PVs is an emerging research area; therefore, this comprehensive review can be considered as a reference for future development and innovations.

Authors: Nuez Fernando
Published: December 2021

In this paper, algebraic relations were established that determined the invariance of a transformed number after several transformations. The restrictions that determine the group structure of these relationships were analyzed, as was the case of the Klein group. Parametric Kr functions associated with the existence of cycles were presented, as well as the role of the number of their links in the grouping of numbers in higher-order equivalence classes. For this, we developed a methodology based on binary equivalence relations and the complete parameterization of the Kaprekar routine using Ki functions of parametric transformation.

Authors: Tamari Rimon , Grushko Benjamin , Meshi Louisa
Published: December 2021

Binary high temperature “Al3Mn” (T-phase) and its extensions in ternary systems were the subjects of numerous crystallographic investigations. The results were ambiguous regarding the existence or lack of the center of symmetry: both Pna21 and Pnam space groups were reported. Our research on the Al–Mn–Pt T-phase allowed concluding that inside a continuous homogeneity region, the structure of the Al-rich T-phase (e.g., Al78Mn17.5Pt4.5) belongs to the non-centrosymmetric Pna21 space group, while the structure of the Al-poor T-phase (such as Al71.3Mn25.1Pt3.6) is centrosymmetric, i.e., Pnam. Following metallurgical and crystallographic considerations, the change in the symmetry was explained.
Thermal Conductivity Determination of Ga-In Alloys for Thermal Interface Materials Design
Authors: Maivald Parker , Sridar Soumya , Xiong Wei
Published: December 2021

Thermal interface material (TIM) that exists in a liquid state at the service temperature enables efficient heat transfer across two adjacent surfaces in electronic applications. In this work, the thermal conductivities of different phase regions in the Ga-In system at various compositions and temperatures are measured for the first time. A modified comparative cut bar technique is used for the measurement of the thermal conductivities of GaxIn1−x (x = 0, 0.1, 0.214, 0.3, and 0.9) alloys at 40, 60, 80, and 100 °C, the temperatures commonly encountered in consumer electronics. The thermal conductivity of liquid and semi-liquid (liquid + β) Ga-In alloys are higher than most of the TIM’s currently used in consumer electronics. These measured quantities, along with the available experimental data from literature, served as input for the thermal conductivity parameter optimization using the CALPHAD (calculation of phase diagrams) method for pure elements, solution phase, and two-phase region. A set of self-consistent parameters for the description of the thermal conductivity of the Ga-In system is obtained. There is good agreement between the measured and calculated thermal conductivities for all of the phases. Due to their ease of manufacturing and high thermal conductivity, liquid/semi-liquid Ga-In alloys have significant potential for TIM in consumer electronics.

Authors: Vaezi Atefeh , Meysamie Alipasha
Published: December 2021

COVID-19 vaccines are supposed to be critical measure for ending the pandemic. Governments had to decide on the type of vaccine to provide for their population. In this decision-making process, cost-effectiveness analysis is considered a helpful tool. This study is a cost-effectiveness analysis utilized to calculate the incremental cost per averted disability-adjusted life year (DALY) by vaccination compared to no vaccination for different COVID-19 vaccines. The incremental cost-effectiveness ratio (ICER) for a vaccination with COVID-19 vaccines was estimated at 6.2 to 121.2 USD to avert one DALY and 566.8 to 10,957.7 USD per one death. The lowest and highest ICERs belong to Ad26.COV2.S and CoronaVac, respectively. Considering the scenario of Iran, vaccines that are recommended include ad26.cov2.s, chadox1-S, rAd26-S + rAd5-S, and BNT162b2 in the order of recommendation.

Introduction: Despite global efforts to contain the illness, COVID-19 continues to have severe health, life, and economic repercussions; thus, maintaining vaccine development is mandatory. Different directions concerning COVID-19 vaccines have emerged as a result of the vaccine’s unpredictability. Aims: To study the determinants of the attitudes of healthcare workers (HCWs) to receiving or refusing to receive the vaccine. Methods: The current study adopted an interviewed questionnaire between June and August 2021. A total of 341 HCWs currently working at Assiut University hospitals offered to receive the vaccine were included. Results: Only half of the HCWs (42%) accepted the COVID-19 vaccine. The most common reason that motivated the HCWs was being more susceptible than others to infection (71.8%). On other hand, the common reasons for refusing included: previously contracted the virus (64.8%); did not have time (58.8%); warned by a doctor not to take it (53.8%). Nearly one-third of nonaccepting HCWs depended on television, the Internet, and friends who refused the vaccine for information (p < 0.05). In the final multivariate regression model, there were six significant predictors: sex, job category, chronic disease, being vaccinated for influenza, and using Assiut University hospital staff and the Ministry of Health as sources of information (p < 0.05). Conclusion: Misinformation and negative conceptions are still barriers against achieving the desired rate of vaccination, especially for vulnerable groups such as HCWs.

Authors: Yang Min , Wang Tao , Guo Chunji , Ellis Chris , Liao Yuefeng
Published: December 2021

In this paper, a particular form of flywheel hybrid powertrain, namely, the Integrated Kinetic Energy Recoup Drive (i-KERD) is fully explored and its applications for EVs, HEVs and FCEVs in recent years to show the energy-savings and performance enhancement potential of this innovative powertrain technology. It is shown that the i-KERD is a small highspeed flywheel integrated into an e-CVT, or power-split hybrid drive. Under NEDC or WLTC, typically it can achieve some 40% energy savings and >50% gain in 0–100 kph acceleration due to effective regenerative braking mechanism of the integrated flywheel power system. In addition to its “peak-shaving” capability, the highly-efficient, long-life flywheel power on-board, is able to keep the kinetic energy of the vehicle fully recycled, rather than dissipated during braking. The i-KERD technology has also been applied to urban railway transportation (i.e., underground railway) and off-road heavy construction equipment, where regenerative braking plays a great role on energy efficiency.
Suppression of Cross-Coupling Effect of Hybrid Permanent Magnet Synchronous Motor with Parallel Magnetic Circuit
Authors: He Xiao , Bao Guangqing
Published: December 2021

Hybrid permanent magnet synchronous motor (HPMSM) has attracted increased attention in recent years due to its adjustable air gap flux. However, as a result of the cross-coupling effect of high- and low-coercive permanent magnets, the precise magnetic adjustment of HPMSM has become increasingly difficult. In order to weaken the cross-coupling effect, two methods of adding magnetic barrier and exciting coil are adopted in this paper. First, the equivalent magnetic circuit model is established, and the theoretical rationality of the weakening method is analyzed. Second, the electromagnetic performance of two weakening methods are analyzed based on the finite element analysis. Finally, the rationality of the theoretical analysis is verified, which provides the structure basis for the precise magnetic adjustment of the hybrid permanent magnet motor.
A Cooperative Two-Step Vertical Handoff Scheme with Mobility Prediction
Authors: Chang Shih Yu , Ho Pin-Han
Published: December 2021

As mobile communication evolves into 3G beyond, the interworking of multiple heterogeneous networks serves as the major effort for taking the best advantage of different technologies available in supporting various emerging services, such as VoIP, Video on Demand (VoD), and IP Television (IPTV), etc. Vertical handoff is one of the key mechanisms in achieving Always Best Connected (ABC) for the mobile users by leveraging the benefits of deploying different types of networks for provisioning seamless handoff/roaming services in presence of user mobility. This paper aims to introduce a novel cooperative two-step vertical handoff scheme for the integration of 3G Wireless Wide-Area Networks (WWAN) and the IEEE 802.11 Wireless Local-Area Networks (WLANs). The proposed scheme is based on the cooperation based access point (AP) and mobile station (MS), where the AP manipulates the sensed signal strength to determine whether a pre-handoff action should be initiated. To improve the accuracy of user mobility prediction, a Markov model that incorporates with a novel parameter training process is developed at the AP for acquiring the hotspot geographic arrangement, such as the location of aisles, walls, and entrances/exits, etc., which is considered as the major factor of determining the user mobility patterns in an indoor hotspot. We will justify feasibility and discuss the operation complexity of the proposed cooperative vertical handoff. Moreover, error propagation due to inaccurate signal strength measurement is studied through Maximum Likelihood estimation. Finally, we will clearly demonstrate the merits gained by using the proposed two-step vertical handoff mechanism through extensive simulation, where the derived analytical models are verified.

Published: December 2021

Machine translation is one tool of Google that presents various languages to translate. As a translator machine, the results of Google Translate are not always perfectly correct. The result of translation can be called pre-translation, which is still needed to be revised. Pramoedya Ananta Toer's Arok Dedes story is one of the Javanese stories that contain elements of culture. Translating texts which contain elements of a culture is not easy because one region to another have different cultures, so that it is difficult to look for parallel words that contain cultural, religious, social, customs, social organization, procedure, sign language, and ecology elements, and Google cannot translate the term of cultural words easily. This study is aimed at two main purposes: (1) finding out the types of lexical errors made by machine translation in translating cultural text and (2) knowing the most dominant type of lexical errors made by machine translation in translating cultural text. This study was carried out in a population of 553 pages of Pramoedya Ananta Toer's Arok Dedes. A simple random sampling technique was done to select samples. The total samples taken in this study were 30% of the population. The study results are that there are only 9 types of the total 21 types of lexical errors, namely calque, misselection, consonant-based type, false friend, vowel-based type, inappropriate co-hyponym statistically weighted preferences, semantically determined word selection, and preposition partners. The most dominant error of lexical errors is calque.

A conceptual model of a transition from technogenic to human-induced globalization
Authors: Batukova Louise , Bagdasaryan Naira , Bagdasaryan Lusine
Published: December 2021

Globalization is a fundamental integrative social mechanism, in which two stages can be distinguished: “technogenic globalization” and “human-induced globalization”. The result of a phase transition from the first stage to the second should be the final formation of an information society. The aim of the study was the theoretical substantiation of globalization as a mechanism for a transition to an information society, and identification of the role and place of technogenesis in it. The paper considers the essence of a transition to an information society in the context of the replacement of technogenic globalization with human-induced globalization, and draws a conclusion about the place of technogenesis and artificial intelligence, as its institution, in human-induced globalization. It is shown that at the present stage, human-induced globalization should be implemented with a focus on the following directions of technogenesis: a) formation of breakthrough directions of development of the “Human Variable of society”; b) ensuring the demand for innovative development; c) acquisition by society of a new development resource – “human-energy-informational plasma”; d) formation of a new “capital” mechanism – the mechanism of self-growth of the value of social life on the basis of the investment flow of human-energy-informational plasma.

Este artículo propone un diálogo interdisciplinar entre sociología y lingüística, para abordar algunos problemas teórico-metodológicos implicados en la tensión entre lo individual y lo social. En esta dirección, y con vistas a analizar problemáticas sociales de la Argentina, avanzamos en una propuesta que ensaya puentes entre el análisis del discurso y la teoría sociológica contemporánea. Para ello, desarrollamos una mirada crítica sobre nuestras disciplinas que apunta a destacar el carácter interpretativo y situado de la práctica de la investigación social, profundizando en una revisión sobre los alcances y limitaciones del análisis del discurso en su aproximación a las “experiencias” de las agentes sociales, y articulando esta revisión con los aportes de la corriente sociológica micro-interaccionista. La revisión de estos dos campos teóricos nos permite avanzar en una propuesta metodológica que enfatiza la pertinencia de analizar de forma combinada los aspectos micro de las interacciones cara a cara y los aspectos estructurales que las atraviesan. Para sellar este desafío heurístico, proponemos ejemplos recuperados de nuestras propias investigaciones.

El plomo y sus diferentes formas químicas se han utilizado ampliamente en la industria durante los últimos años y el resultado es la alta contaminación detectada en el agua y el suelo. Se aislaron microorganismos resistentes al plomo (II) de muestras líquidas recolectadas en Mina Asientos, Cochabamba-Bolivia. Se aislaron once cepas en medio sólido con 200 ppm de Pb (II) y se seleccionaron 4 cepas para remoción de metales en muestras líquidas, una cepa presentó los valores de remoción de Pb (II) más altos para 250 ppm de Pb (II). La cepa seleccionada designada como MA-4 se sometió a estudios filogenéticos y mostró una similitud de secuencia del 99,9% con Pseudomonas monteilii. La biosorción sigue los modelos de isotermas de Langmuir y Freundlich, con valores de qmax y Kf de 166,67 y 11,09, respectivamente. Estos resultados implicaron una fuerte capacidad de unión a la biomasa muerta y su potencial aplicación en el proceso de biosorción.
Exilic/Idyllic Shakespeare: Reiterating Pericles in Jacques Rivette’s Paris nous appartient
Authors: Calbi Maurizio
Published: December 2021

Jacques Rivette’s Paris nous appartient (1961) is about a literature student, Anne Goupil, who becomes involved with a group of bohemians centering around the absent figure of Spanish musician, Juan. The film incorporates the attempt by theatre director Gérard Lenz – in many ways a simulacrum of Rivette himself – to stage Pericles, even though this is a play that he himself defines as “incoherent” and “unplayable.” This essay explores the significance of this incorporation, and shows how the reiterated, fragmentary rehearsals of this “unplayable” play are essential to an understanding of the (disjointed) logic of the film as well as the atmosphere of conspiracy it continually evokes. It also argues that the “Shakespeare” included in the film is an “exilic Shakespeare” that does not properly belong, a kind of spectre haunting the film characters. This construct uneasily coexists with a version of “Shakespeare” that the film simultaneously emphasizes – a “Shakespeare” that takes place “on another level” (in Anne’s words), an idyllic and idealistic entity.
Anthony Munday’s Palmerin d’Oliva: Representing sexual threat in the Near East
Authors: Ortiz-Salamovich Alejandra
Published: December 2021

This article explores how Anthony Munday’s Palmerin d’Oliva (1588), Part II, portrays the threat of Muslims in the Near East. Munday’s source is the French L’Histoire de Palmerin d’Olive (1546), which Jean Maugin had translated from the anonymous Spanish chivalric romance Palmerín de Olivia (1511). I focus on the way that the description of the Muslim menace changes in the course of translation. I argue that both the French and English translators manipulate medieval and early modern sexual stereotypes used to describe Muslim culture in order to heighten the sense of Islamic aggression and the holiness of Christianity as a counter to its threat. Munday’s translation, in particular, represents the ambivalent views that his contemporary England held about Islam and the Near East, and also highlights the sanctity of Christian chastity and marriage, which are issues that he also develops in Part I of the Palmerin d’Oliva.
“The intolerable business": Religion and diplomacy under Elizabeth’s rule
Authors: Oliveira Susana
Published: December 2021

Within the scope of foreign affairs between Portugal and England during Elizabeth’s rule, numerous events indicate the challenges faced by the Portuguese ambassadors on their missions. Regrettably, little is known about these envoys and one rarely finds any reference to their names or their diplomatic accomplishments in Early Modern studies. This paper focuses on a diplomatic incident which involved Francisco Giraldes, a Portuguese resident ambassador in England, aiming to shed some light on “the intolerable business” that led to a confrontation with the Bishop of London, Edwin Sandys. Attending a Catholic Mass in the context of the Elizabethan Religious Settlement involved certain challenges that should be considered. Diplomats, however, enjoyed certain immunities, including the droit de chappelle, and were allowed to hold Catholic services in their ambassadorial residences. But in March 1573, while Mass was being held, Francisco Giraldes’s residence was raided by the Sheriff of London’s men, working under the Bishop of London’s instructions. The ongoing tension between the religious and the political areas of power was, thus, exposed. Two letters, written by the Bishop of London, included in the Lansdowne Manuscripts Collection of the British Library, registered the event. As Sandy’s correspondence appears to be the single piece of surviving evidence regarding this diplomatic incident, it stands to reason that its analysis will provide significant insight into the coexistence, as well as the clash, of oppositional forces, while further contributing to an interpretation of Anglo-Portuguese affairs in Early Modern times.
Nelly or Ellen? Revamping the first English actresses in contemporary popular culture
Authors: Martínez-García Laura
Published: December 2021

The first British actresses have been the focus of extensive scholarly study, transposing the boundaries of academic life and irrupting in popular culture and becoming a part of the public imagination and folklore. This paper studies the perception we have inherited of “Pretty, Witty Nell,” probably the best-known actress of the Restoration, through the analysis of two novels—Priya Parmar’s Exit the Actress and Gillian Bagwell’s The Darling Strumpet—that reconstruct Gwyn’s life turning the “Protestant Whore” into a learned lady and a devoted mother. This revamping of her figure not only entails the erasure of the subversive potential of actresses’ break with the public-masculine/private-feminine dichotomy, but it also works as an attempt at neutralizing the threat that these “public” women pose to the gender roles that became normative in the seventeenth century and that are still seen as such nowadays.
Rupert Goold’s Macbeth (2010): Surveillance society and society of control
Authors: Huertas Martín Víctor
Published: December 2021

This article deals with Rupert Goold’s film version of Macbeth (2010). Based on a stage production, this film is set in an unspecified Soviet country. I will analyze Goold’s creation of a stage-to-screen hybrid recording framed as a surveillance film. Relying on Michel Foucault’s and Gilles Deleuze’s works as well as various contributions made by Cultural Materialist and New Historicist critics, I intend to explore the power relations in this surveillance film. I will also examine how the surveillance film conventions deployed by Goold turn the narrative into a meta-filmic event. This allows the viewer to perceive surveillance as part of the subject matter of the story and as inseparable from its narrative structure. Eventually, this will serve to explore how surveillance entirely transforms the filmscape. What begins as a film set in a surveillance society ends up as an environment dominated by a society of control.
Shakespeare our contemporary in 2016: Margaret Atwood’s rewriting of The Tempest in Hag-Seed
Authors: Muñoz-Valdivieso Sofía
Published: December 2021

Margaret Atwood’s novel Hag-Seed (2016) is a retelling of The Tempest that transfers the actions from the magic island of the original play to present-day Canada: the avant-garde artistic director of a Shakespearean Festival is ousted from his job by his more world-savvy deputy, lives in isolation for twelve years and plots his revenge, which will involve a staging of The Tempest at the local prison where he has been teaching for some time as Mr Duke. Hag-Seed is part of a larger project of fictional retellings of the Bard’s plays conceived by Hogarth Press for the commemoration of the 400th anniversary of his death, a moment when Shakespeare’s cultural capital seems to be circulating more energetically than ever. The present article analyses Hag-Seed as a neo-Shakespearean novel that is original in the double sense of the term that Atwood’s teacher Northrop Frye so frequently remarked: imaginative, innovative, and inventive but also true to its fountain and origins.
