Theophanes, Potamon and Mytilene’s Freedom
Authors: Pawlak Marcin N.
Published: January 2021

Theophanes and Potamon of Mytilene, two Greek euergetes who sought to serve their home polis in a rapidly changing political landscape of the late Roman Republic and early Principate, took an active interest in the politics of the day and sought to lobby Roman elites on Mytilene’s behalf. Theophanes befriended and advised Pompey, contributing to Pompey’s decision to pardon and liberate Mytilene after the city’s ignominious participation in the Asiatic Vespers, whereas Potamon served as Mytilene’s ambassador in Rome, adroitly championing its city’s interests. Two politicians bettered Mytilene’s political status in the tumultuous period of transformation from a republic to an autocracy and ensured that the city maintained its freedom until the times of the Flavians.
Irregularity of Post Mining Deformations as Indicator Revealing Effects of Processes of Unknown Origin in Area of Bochnia
Authors: Szczerbowski Zbigniew
Published: January 2021

The presented work deals with the problem of terrain surface and rock mass deformation in the area of the Bochnia Salt Mine. The deformations are related to natural causes (mainly the tectonic stress of the Carpathian orogen) as well as anthropogenic ones related to the past mining activity conducted directly under the buildings of the town of Bochnia. The discussed characteristics of land surface deformation are important from the point of view of threats to surface features and contribute to spatial development. Particularly anomalous zones of observed subsidence basins are examined as places of second order deformation effects. The author presents a method of determinations of these anomalous areas and he discusses their origins.
The Apparent Displacement Method as a Tool in Leveling Data Processing Applied for Validated Determination of Ground Deformation
Authors: Szczerbowski Zbigniew , Gawałkiewicz Rafał
Published: January 2021

Area of Inowrocław town is considered as tectonically active due to halotectonic movement of salt dipair situated there. The geodetic surveys carried out for the determination of terrain surface deformations over the years revealed characteristics of the movement. The evaluated vertical displacements based on measurements of benchmarks show different characteristics, depending on distant points assumed as reference benchmarks. This raises problems in analysis, interpretation of the results and decision makings in master planning. The authors demonstrate a method of adjustment calculations that minimize the inconsistencies between previously elaborated heights and inconsistencies of points considered as stabile benchmarks. Thanks to the new approach the point considered as reference were recognized as unstable. And for the others more consistent values of the displacements were obtained: several benchmarks demonstrated higher difference of displacement values in compare to the initial approach in adjustments ranging in the interval of –9 mm – +3 mm.
El derecho a la vivienda: la seguridad jurídica de la tenencia y el papel del Defensor del Pueblo en su garantía
Authors: Celi Maldonado Alejandra
Published: January 2021

La seguridad jurídica de la tenencia, es decir el derecho de quienes disponen de una vivienda a conservarla, es uno de los elementos esenciales del derecho a la vivienda según la interpretación del Pacto Internacional de Derechos Económicos Sociales y Culturales realizada por el Comité de Derechos Económicos Sociales y Culturales. En España, como consecuencia de la crisis económica, este elemento del derecho fue seriamente vulnerado, principalmente, mediante los procedimientos de ejecuciones hipotecarias y los desalojos. En este artículo, luego de describir el marco jurídico general del derecho a la vivienda, se analizan las repuestas de ese Comité ante las comunicaciones individuales correspondientes a España y las actuaciones relevantes del Defensor del Pueblo para garantizar la seguridad jurídica de la tenencia en ese Estado.
Una perspectiva de derechos sociales en la labor de las defensorías del pueblo: una apuesta por la progresividad
Authors: Aba Catoira Ana
Published: January 2021

El Derecho Internacional de los Derechos Humanos ha consolidado la garantía de los derechos sociales, económicos y culturales, cuya realización progresiva es asumida como obligación por los Estados Partes. El incumplimiento reiterado de dicho compromiso pone de manifiesto la falta de voluntad pública, y también privada, por satisfacer derechos básicos y esenciales vinculados a la vida digna. Los documentos de las organizaciones internacionales y las resoluciones dictadas en su interpretación ofrecen todos los elementos y apoyos para lograr la efectividad de estos derechos a través de políticas públicas articuladas sobre el principio de no regresividad. En este orden de cosas, las Defensorías del Pueblo como autoridad de persuasión deben incluir en sus argumentaciones una perspectiva internacional de derechos humanos, poniendo énfasis en el desconocimiento de estos parámetros por las instituciones nacionales y reforzando su autoridad en el Derecho Convencional.
El papel del Defensor del Pueblo destacando la importancia de los seguros de salud privados para el derecho a la protección de la salud de las personas con discapacidad
Authors: Bolívar Oñoro María Del Val
Published: January 2021

Esta contribución hace un breve repaso al derecho a la protección de la salud en España, poniendo de relieve las dificultades que han surgido en torno a él a raíz del Real Decreto-Ley 16/2012. Dificultades que se traducen en la posibilidad de no poder acceder de manera gratuita a determinados procedimientos o tratamientos en el futuro, acentuando esta situación el hecho de que la discapacidad sea un obstáculo para que muchas personas aminoren este riesgo con un seguro de salud privado. El Defensor del Pueblo desde finales del Siglo XX venía haciéndose eco de las barreras que las personas con discapacidad encuentran para acceder a los seguros de salud privados y del rol que estos tienen en el derecho a la protección de la salud contemplado en el artículo 43 de la Constitución. Sin embargo, no ha sido hasta 2011 y 2018 cuando se han producido avances legislativos en esta materia.
La situación de los inmigrantes y el mundo laboral
Authors: Abdillahi Bahdon Mohamed
Published: January 2021

Con el crecimiento de las migraciones de estas últimas décadas, la mujer inmigrante originaria de los países del Sur ha entrado en el mundo laboral. Como el hombre, las oportunidades laborales motivan muchas mujeres subsaharianas en emprender proyectos personales o/y colectivos de migración hacia otros contextos socioeconómicos. Durante mucho tiempo su presencia y su protagonismo en los movimientos migratorios han dejado indiferentes a investigadoras e investigadores en ciencias sociales las/los cuales reflejaban en sus estudios únicamente las migraciones desde la perspectiva del hombre, es decir masculina. Que sigua su marido o que vaya sola, tener un empleo es también una prioridad. Se la han mantenido en la invisibilidad laboral y social. El presente trabajo se centra en primer lugar sobre la discriminación que sufren las mujeres inmigrantes subsaharianas residentes en la Región de Murcia. En segundo lugar, trata la migración de estas mujeres en las últimas décadas fuera de sus países de origen. Y en tercer lugar se analiza cómo, a pesar de la discriminación y de los estereotipos de la sociedad de residencia, desarrollan estrategias personales y/o colectivas para conseguir un empleo en un mercado dual y etnificado, y por lo tanto discriminatorio.

Authors: H. H. Hоjiev  , N.N.Xabibova
Published: January 2021

Treatment of chronic apical periodontitis (CVP) is one of the most important and not fully solved problems of therapeutic dentistry. This is primarily due to the significant prevalence of this disease, the complexity and complexity of medical manipulations, a large percentage of failures and complications in treatment, as well as the lack of stability of the results obtained using known treatment methods. Therefore, the constant search for new and more effective means and methods of treatment of CVP is one of the urgent tasks of modern dentistry.
Open defecation in Kenya: A Box-Jenkins Arima Approach
Authors: Smartson. P. NYONI  , Thabani NYONI
Published: January 2021

Using annual time series data on the number of people who practice open defecation in Kenya from 2000 – 2017, the study predicts the annual number of people who will still be practicing open defecation over the period 2018 – 2021. The authors apply the Box-Jenkins ARIMA methodology. The diagnostic ADF tests show that the ODK series under consideration is an I (1) variable. Based on the AIC, the study presents the ARIMA (0, 1, 2) model as the optimal model. The diagnostic tests further indicate that the presented model is quite stable and its residuals are stationary in levels. The results of the study indicate that the number of people practicing open defecation in Kenya is likely to decline, although slightly, over the period 2018 – 2022, from approximately 9.9% to almost 8.2% of the total population. Hence, it is possible for Kenya to completely eliminate the practice of open defecation by 2030. The study basically suggested a 3-fold policy recommendation to be put into consideration, especially by the government of Kenya.
REPRODUCTIVE POTENTIAL OF THE KARAKUL SHEEP SHEEP OF THE KARAKALPAK BREED TYPE DEPENDING ON THE CONDITIONS IN THE NORTHWEST OF KYZYLKUM
Authors: Akhmet Abdirazakovich Urimbetov
Published: January 2021

The article describes the methods of increasing the breeding productivity of Karakul sheep of the Karakalpak breed type, depending on the diet and seasonality of the sheep's nutrition for the mating period in the North-West Kyzylkum desert. Karakul breeding is the most important branch of agriculture in Karakalpakstan, therefore it is very important to increase the number of livestock, and the mating of Karakul sheep is a very important point in animal breeding. The object of research was the herds of sheep of the Karakalpak breed type in the breeding farm in the North-West Kyzyl Kum. The results of the study of the reproductive potential of sheep showed that in order to increase the number of pregnant queens one and a half months before the planned measures for insemination or mating, enhanced feeding of the sheep and a sufficient amount of balanced and succulent green fodder is necessary. Sheep also need concentrated feed of at least kg per head per day. The individual characteristics of the animals were also taken into account to determine the best time for insemination. For this, constant supervision over the behavior of the tribal members of the herd was organized. Observations also showed that the hunting period in sheep lasts for 1-2 days. and is repeated after 3 weeks. The seasonality of sexual hunting is most associated with autumn and the beginning of winter. In extreme heat and severe cold, hunting is weak.

Authors: Obead Imad Habeeb , Omran Hassan Ali , Fattah Mohammed Yousif
Published: January 2021

The objective of the present study is to make a database that describes the leaching-permeability behavior of collapsible gypseous soil. The data will be implemented to develop ANN prediction models for predicting the saturated coefficient of permeability and percentage of solubility by weight. The complex soil behavior and tedious and time consume in soil testing have driven researchers to use Artificial Neural Network (ANN) as tool for prediction. The objectives of the study were to investigate leaching-permeability behavior of collapsible gypseous soils and to develop ANN models for estimating the saturated coefficient of permeability and solubility of the soils. The MATLAB R2015a software was used to predict the saturated coefficient of permeability and the solubility percentage by weight of gypseous soils. The dataset used in this work included (513) records of experimental measurements extracted from leaching-permeability tests conducted on gypseous soil samples taken from Baher Al-Najaf in Iraq. Four input variables were investigated to have the most important influence on the permeability and solubility percentage by weight. According to the achieved statistical analysis, the ANNs model have a reliable capability to find out the predictions with a high-level of accuracy. The gypseous soils exhibited a high rate of dissolution of soluble minerals content, which caused increase in the coefficient of permeability as the soil samples reach the state of long-term full saturation.

Authors: Rahman Md. Mijanoor , Ismail Mohd. Tahir , Awang Norhashidah , Majahar Ali Majid Khan
Published: January 2021

Lane-changing (LC) problem may cause serious accidents or create a painful traffic jam at multi-lane roads. Existing LC simulation model was created with some limitations (less fitted, without velocity and acceleration profiles, high curvature) by using well known trajectory curve such as Hyperbolic Tangent Curve (HTC), Sine-Based Curve (SC), Polynomial Curve (PC). In this study, a new parametric curve had been proposed by using curvilinear coordinate system and fitted against Next Generation Simulation (NGSIM) real dataset. Further, new profiles of velocity and acceleration were designed using the proposed LC trajectory curve. The curvature of proposed model was zero-based curvature both at LC starting and ending points. This proposed curvature was compared with two models such as HTC and SC. The average root-mean-square-error of proposed model decreased with 1.84% for left LC and 15.48% for right LC compared to HTC model and 1.74% for left LC and 15.60% for right LC compared to SC model. Similarly, the proposed model for velocity and acceleration profiles improved significantly from PC model. The proposed parametric curve solves the gap and collision points of LC vehicle with a front vehicle and rear vehicle at target lane and can be used in real LC path planning.
Combined Impacts of Predation, Mutualism and Dispersal on the Dynamics of a Four-Species Ecological System
Authors: Aliyu Murtala Bello , Mohd Mohd Hafiz
Published: January 2021

Multi-species and ecosystem models have provided ecologist with an excellent opportunity to study the effects of multiple biotic interactions in an ecological system. Predation and mutualism are among the most prevalent biotic interactions in the multi-species system. Several ecological studies exist, but they are based on one-or two-species interactions, and in real life, multiple interactions are natural characteristics of a multi-species community. Here, we use a system of partial differential equations to study the combined effects of predation, mutualism and dispersal on the multi-species coexistence and community stability in the ecological system. Our results show that predation provided a defensive mechanism against the negative consequences of the multiple species interactions by reducing the net effect of competition. Predation is critical in the stability and coexistence of the multi-species community. The combined effects of predation and dispersal enhance the multiple species coexistence and persistence. Dispersal exerts a positive effect on the system by supporting multiple species coexistence and stability of community structures. Dispersal process also reduces the adverse effects associated with multiple species interactions. Additionally, mutualism induces oscillatory behaviour on the system through Hopf bifurcation. The roles of mutualism also support multiple species coexistence mechanisms (for some threshold values) by increasing the stable coexistence and the stable limit cycle regions. We discover that the stability and coexistence mechanisms are controlled by the transcritical and Hopf bifurcation that occurs in this system. Most importantly, our results show the important influences of predation, mutualism and dispersal in the stability and coexistence of the multi-species communities

Published: January 2021

In this paper, Adaline Neural Network (ADNN) has been explored to simulate the actual signal processing between input and output. One of the drawback of the conventional ADNN is the use of the non-systematic rule that defines the learning of the network. This research incorporates logic programming that consists of various prominent logical representation. These logical rules will be a symbolic rule that defines the learning mechanism of ADNN. All the mentioned logical rule are tested with different learning rate that leads to minimization of the Mean Square Error (MSE). This paper uncovered the best logical rule that could be governed in ADNN with the lowest MSE value. The thorough comparison of the performance of the ADNN was discussed based on the performance MSE. The outcome obtained from this paper will be beneficial in various field of knowledge that requires immense data processing effort such as in engineering, healthcare, marketing, and business.
Optimisation of Culture Conditions for PLA-food-packaging Degradation by Bacillus sp. SNRUSA4
Authors: Sawiphak Suwapha , Wongjiratthiti Aroon
Published: January 2021

Polylactic acid (PLA) is increasingly used in food-packaging production. The screening of PLA-food-packaging-degrading bacteria and optimisation of culture conditions for the PLA-food-packaging degradation by PLA-food-packaging-degrading bacteria were investigated for bioplastic waste management purposes. Only bacterial strain SNRUSA4 exhibited an increase in optical density (OD) in Basal Medium (BM) supplemented with 1.0 g/L of PLA-food-packaging as sole carbon source after 4 weeks of incubation. A weight loss of 7.3% and the rough and porous surface of PLA-food-packaging indicated that SNRUSA4 was a PLA-food-packaging-degrading bacterium. SNRUSA4 was able to degrade pure PLA which was confirmed from the clear zone formation around its colony on emulsified pure PLA agar plate. The 16S rRNA gene sequence of SNRUSA4 showed the similarity with thirteen Bacillus species. Hence, the strain SNRUSA4 was assigned as Bacillus sp. SNRUSA4. Response surface methodology with Box-Behnken Design was used to optimise the culture conditions including yeast extract concentration, initial pH value, temperature and agitation speed for growth and PLA-food-packaging degradation of Bacillus sp. SNRUSA4. The optimal conditions of Bacillus sp. SNRUSA4 was discovered in BM at initial pH value 7.02 with yeast extract concentration of 2.56% and agitated at 205.28 rpm at 31.68°C. Under optimal conditions, the OD of Bacillus sp. SNRUSA4 was up to 1.955, and the different OD between before and after optimisation was up to 1.752. Furthermore, the PLA-food-packaging weight loss also increased from 7.30% to 87.10% indicating that the PLA-food-packaging degradation under optimal conditions was higher than the unoptimised conditions. Therefore, Bacillus sp. SNRUSA4 is an efficient strain for degradation of PLA and PLA-food-packaging.

Authors: Mohd Kasihmuddin Mohd Sophian , Che Cob Zaidi
Published: January 2021

An assessment of community of benthic macroinvertebrates in waters northwards of Pulau Indah, Klang was made with the main objective to determine distribution and diversity of benthic macroinvertebrates as well as to establish possible correlation between the community’s distributions with environmental parameters. The sediments were obtained via Ponar Grab (0.023 m2 mouth area), followed by filtration (500 μm) and laboratory sorting in order to extract all specimens from sediments. The specimens were identified to the lowest taxonomic hierachy as possible. The physical parameters such as organic carbon (TOC) and grain size distributions were analysed. A total of 775 annelids, 15 arthropods, 12 echinoderms and 32 molluscs individuals were identified and recorded in six stations overall. Family Cirratulidae accounted to the highest numbers of the Annelids (n=358), whilst Cerithidae recorded as highest numbers of Molluscs. Station 5, 6 and 1 recorded the highest diversity index (H’=2.1845), evenness index (J’=0.6316) and richness index (Dmn=22.0454) respectively. Principal Component Analysis indicated sediment particle size as the major connector on all stations, with different station correlated to certain sizes of sediment particle. Pearson correlation analysis showed positive correlations between environmental parameters with eight benthic taxa in this study, with most correlations were on specific sediment particle size. As the study of benthic community is still inadequate in most of Malaysians waters, particularly in highly industrialised area such as waters in Port Klang, this study can serve as a starting point for any future studies concerning ecological disturbance affecting benthic community in Malaysian waters.
Determination of Pesticide Residuals in Soil and Tomato Fruits from Two Tomato Production Areas in northern Ghana
Authors: Dari Linda , ADDO Ahmad , DZISI Komla Agbeko
Published: January 2021

Tomato fruit (Lycopersicon esculentum Mill) is an important vegetable commodity in Ghana, as it is consumed daily in many households either heat-treated or without any form of heat treatments. Tomato production is a major source of income for many smallholder producers in Northern Ghana especially through dry season farming when the major supply of tomatoes from Southern Ghana is exhausted. Research conducted for the past decade confirmed the presence of pesticide residues in fruits and vegetables such as cabbage, onion, cucumber, lettuce, tomatoes, okra and pepper. The objective of this study was to identify and estimate pesticide residual levels in the soil and tomato fruits in comparison with the maximum allowable residual limits. The research was carried out in two production communities namely Doba where the “Burkina” variety is mostly grown in the Kassena Nankana East District of the Upper East Region and Bunglung where the “Wosowoso” variety is cultivated in the Savelugu/Nanton Municipality of Northern Region. Soil samples were collected for residue determination before transplanting of tomato seedlings. Matured and ripe tomato fruits were also collected for the determination of the presence and amount of pesticide residues. All soil and plant samples were analysed using high performance liquid chromatography to determine the presence of twenty-four organochlorines and thirteen organophosphate pesticide residues. From the analysis, pesticide residues were present in different variations which ranged from 0.002 – 0.033 and 0.003 – 0.022 (soils) and 0.330 – 1.187 and 0.002 – 0.088 (fruits) for organochlorines and organophosphates respectively for both communities. Levels of pesticide residues were generally above the acceptable maximum residue limits as farmer practices produced fruits with more pesticide residues since the land areas could have been predisposed with residues from previous seasons for other food crops, which could be translocated into the tomato plant and through into the fruits. The presence of pesticide residues could also be attributed to the influence of run-off and drift from other cultivated lands. For effective determination of pesticides residues in the tomato plants, it is essential to use uncontaminated soil and water to facilitate the efficient estimation of pesticide residues in tomatoes and plants in general.
Empirical study on the integration of total least squares and radial basis function neural network for coordinate transformation
Authors: KUMI-BOATENG Bernard , ZIGGAH Yao Yevenyo
Published: January 2021

Total Least Squares (TLS) is noted to be a solution approach to solving several geodetic problems. The method has the ability to estimate unknown quantities that are useful for many geodetic applications. Hence, the main objective of this study was to improve the estimation performance of TLS via Radial Basis Function Neural Network (RBFNN) in coordinate transformation. This hybrid approach called TLS-RBFNN was applied to Ghana geodetic reference network, which has a coverage area of 79857 km2 representing 33.5% of the total land mass (238540 km2). A comparative performance analysis of TLS, RBFNN and TLS-RBFNN was carried out using Root Mean Square Horizontal Error (RMSHE) and Standard Deviation (SD). Based on the testing results, it was found that the TLS-RBFNN improved the transformation accuracy of RBFNN and TLS by 20.2% and 37.3% based on the RMSHE. In addition, it was observed that the TLS-RBFNN improved the transformation precision based on SD by 0.37% and 8.52%, respectively. Furthermore, the Bayesian Information Criterion (BIC) applied confirmed the superiority of the hybrid approach than using TLS and RBFNN as independent transformation methods. Consequently, the hybrid approach is recommended for enhanced coordinate transformation results in Ghana geodetic reference network.

Authors: Vargas Lucas Antônio , Magro Cristian Baú Dal , Mazzioni Sady
Published: January 2021

O objetivo do estudo é verificar o efeito moderador do gerenciamento de resultados na relação entre governança corporativa e o custo de capital de terceiros das companhias abertas listadas na [B]3, no período de 2012 a 2017. Inicialmente foram feitas análises descritivas e posteriormente utilizou-se a técnica de dados em painel. Os resultados revelam que as empresas com maior nível de governança corporativa conseguem captar capital de terceiros a um custo menor, contudo, estas mesmas empresas quando associadas ao uso de práticas de gerenciamento de resultados tornam o custo de capital de terceiros mais elevado. De modo geral, as evidências desta pesquisa contribuem para o preenchimento de uma importante lacuna existente na literatura nacional, ao verificar que as empresas que utilizam práticas de gerenciamento de resultados anulam o provável efeito favorável da governança corporativa na redução do custo de capital de terceiros.

Authors: Pecorari Marco
Published: January 2021

Fashion ephemera–from catalogues and invitations to press releases–have long been overlooked by the fashion industry and fashion academics. Fashion Remains redresses the balance, putting these objects centre stage and focusing on the wider creative practice of contemporary fashion designers, photographers, graphic designers, make-up artists and many more. Fashion ephemera are considered not as disposable promotional devices, but as windows into hidden networks of collaboration and value creation in the fashion system.

Taking an interdisciplinary approach, Fashion Remains explores the unseen and privately circulated fashion ephemera produced by today’s most prominent international fashion designers such as Margiela, Yamamoto and Raf Simons. Showcasing a unique archive of materials, it focuses on Antwerp’s avant-garde fashion scene and reveals the potential of these ephemeral objects to evoke and call into question material and immaterial knowledge about the fashion industry’s actors, practices and ideologies.

Ernesto Nathan Rogers
Authors: Sabini Maurizio
Published: January 2021

Architect Ernesto Nathan Rogers (1909–1969) was a towering figure in twentieth-century Italian architecture. Through the work of his collaborative firm (Banfi Belgiojoso Peressutti Rogers, or BBPR), who were responsible for many of the most influential Italian projects of the time, and through the editorship of publications such as Domus and Casabella, Rogers ensured a lasting influence on the field. However his contributions have been largely neglected by scholarship, or more recently have had only superficial understandings attached to them.

Published as part of the Bloomsbury Studies in Modern Architecture series, which brings to light the work of significant yet overlooked modernist architects, this book will re-assess Ernesto Nathan Rogers’ cultural legacy. It will be the first comprehensive, critical work on Rogers in English, and will emphasize Rogers’ vision for the role of the architect as a public intellectual, as well as his commitment to pursue a renewed path of professional and cultural research within the “Modern Project.”

The book also discusses Rogers’ willingness to challenge academic classicized monumentality and the fascist administration to emerge as a leader of Italian design in the aftermath of World War II; his focus on urban design as well as planning; tradition in modernity; history and vernacular culture; and national identity, to bring a detailed account of the work and thought of Ernesto Nathan Rogers to an English-speaking audience for the first time.

Boredom, Architecture, and Spatial Experience
Authors: Parreno Christian
Published: January 2021

Boredom is a ubiquitous feature of modern life. Endured by everyone, it is both cause and effect of modernity, and of situations, spaces and surroundings. As such, this book argues, boredom shares an intimate relationship with architecture—one that has been seldom explored in architectural history and theory.

Boredom, Architecture, and Spatial Experience investigates that relationship, showing how an understanding of boredom affords us a new way of looking at and understanding the modern experience. It reconstructs a series of episodes in architectural history, from the 19th century to the present, to survey how boredom became a normalized component of the everyday, how it infiltrated into the production and reception of architecture, and how it serves to diagnose moments of crisis in the continuous transformations of the built environment.

Erudite and innovative, the work moves deftly from architectural theory and philosophy to literature and psychology to make its case. Combining archival material, scholarly sources, and illuminating excerpts from conversations with practitioners and thinkers—including Charles Jencks, Rem Koolhaas, Sylvia Lavin, and Jorge Silvetti—it reveals the complexity and importance of boredom in architecture.
And This Is My Friend Sandy
Authors: Philips Deborah
Published: January 2021

This book situates the production of The Boy Friend and the Players’ Theatre in the context of a post-war London and reads The Boy Friend, and Wilson's later work, as exercises in contemporary camp. It argues for Wilson as a significant and transitional figure both for musical theatre and for modes of homosexuality in the context of the pre-Wolfenden 1950s.

Sandy Wilson's The Boy Friend is one of the most successful British musicals ever written. First produced at the Players' Theatre Club in London in 1953 it transferred to the West End and Broadway, making a star out of Julie Andrews and gave Twiggy a leading role in Ken Russell's 1971 film adaptation.

Despite this success, little is known about Wilson, a gay writer working in Britain in the 1950s at a time when homosexuality was illegal.

Drawing on original research assembled from the Wilson archives at the Harry Ransom Center, this is the first critical study of Wilson as a key figure of 1950s British theatre. Beginning with the often overlooked context of the Players' Theatre Club through to Wilson's relationship to industry figures such as Binkie Beaumont, Noël Coward and Ivor Novello, this study explores the work in the broader history of Soho gay culture. As well as a critical perspective on The Boy Friend, later works such as Divorce Me, Darling!, The Buccaneer and Valmouth are examined as well as uncompleted musical versions of Pygmalion and Goodbye to Berlin to give a comprehensive and original perspective on one of British theatre's most celebrated yet overlooked talents.
Performance in an Age of Precarity
Authors: Costa Maddy , Field Andy
Published: January 2021

“This magical book is a love letter to the artists whose imagination and cleverness transport us and unite us, and to the beauty and fragility of their performance. When I read it I feel like I am constantly on the joyful edge of falling in love, trying so hard to keep hold of the feelings evoked. A very precious book in our precarious times.” Vicky Featherstone

An anthology of critical essays that draw on a decade of the authors thinking, writing about and working within contemporary performance as critics, producers, dramaturgs, makers, archivists and more.

Together, the 40 essays sketch a map of the contemporary performance landscape from avant-garde dance to live art to independent theatre, tracing the contours of its themes, aims, desires and relationship to the wider worlds of mainstream theatre, art and politics.

Each essay focuses on a particular artist and these include Bryony Kimmings, Dickie Beau, Forced Entertainment, rashdash, Scottee, Selina Thompson, Tania El Khoury and Uninvited Guests.

Reflecting the radical nature of the work considered, the authors attempt to find a new vocabulary and a non-conventional way of considering live performance in these essays.

As both a fresh survey of contemporary performance and an exploration of how to think and write about upstream and avant-garde work, this book should be an essential resource for students, artists and audiences, as well as an accessible entry point for anyone curious to know about the beautiful and strange things happening beyond the UK’s theatrical mainstream.
1997 The Future that Never Happened
Authors: Sayeed Richard Power
Published: January 2021

Beautifully written, brilliantly insightful’

Owen Jones

Tony Blair and Noel Gallagher shaking hands at No. 10. Saatchi’s YBAs setting the international art world aflame. Geri Halliwell in a Union Jack dress. A time of vibrancy and optimism: when the country was united by the hope of a better and brighter future. So why, twenty years on, did that future never happen?

Richard Power Sayeed takes a provocative look at this epochal year, arguing that the dark undercurrents of that time had a much more enduring legacy than the marketing gimmick of ‘Cool Britannia’. He reveals how the handling of the Stephen Lawrence inquiry ushered in a new type of racism. How the feminism-lite of ‘Girl Power’ made sexism stronger. And how the promises of New Labour left the country more fractured than ever.

This lively, rich and evocative book explores why 1997 was a turning point for British culture and society – away from a fairer, brighter future and on the path to our current malaise.
America’s Backyard
Authors: Livingstone Grace
Published: January 2021

The United States has shaped Latin American history, condemning it to poverty and inequality by intervening to protect the rich and powerful. America’s Backyard tells the story of that intervention.

Using newly declassified documents, Grace Livingstone reveals the US role in the darkest periods of Latin American history, including Pinochet’s coup in Chile, the Contra War in Nicaragua and the death squads in El Salvador. She shows how George W Bush’s administration used the War on Terror as a new pretext for intervention; how it tried to destabilise leftwing governments and push back the ‘pink tide’ washing across the Americas. America’s Backyard also includes chapters on drugs, economy and culture. It explains why US drug policy has caused widespread environmental damage yet failed to reduce the supply of cocaine, and it looks at the US economic stake in Latin America and the strategies of the big corporations.

Today Latin Americans are demanding respect and an end to the Washington Consensus. Will the White House listen?
Bipolar Orders: The Two Koreas Since 1989
Authors: Lynn Hyung Gu
Published: January 2021

For over 1500 years before the Empire Windrush docked on British shores, people of African descent have played a significant and far-ranging role in the country’s history, from the African soldiers on Hadrian’s Wall to the Black British intellectuals who made London a hub of radical, Pan-African ideas. But while there has been a growing interest in this history, there has been little recognition of the sheer breadth and diversity of the Black British experience, until now.

This collection combines the latest work from both established and emerging scholars of Black British history. It spans the centuries from the first Black Britons to the latest African migrants, covering everything from Africans in Tudor England to the movement for reparations, and the never ending struggles against racism in between.

An invaluable resource for both future scholarship and those looking for a useful introduction to Black British history, Black British History: New Perspectives has the potential to transform our understanding of Britain, and of its place in the world.
Body Politics in Development
Authors: Harcourt Wendy
Published: January 2021

Body Politics in Development sets out to define body politics as a key political and mobilizing force for human rights in the last two decades. This passionate and engaging book reveals how once-tabooed issues, such as rape, gender-based violence, and sexual and reproductive rights, have emerged into the public arena as critical grounds of contention and struggle.

Engaging in the latest feminist thinking and action, the book describes the struggles around body politics for people living in economic and socially vulnerable communities and covers a broad range of gender and development issues, including fundamentalism, sexualities and new technologies, from diverse viewpoints. The book's originality comes through the author's rich experience and engagement in feminist activism and global body politics and was winner of the 2010 FWSA Book Prize.
First World Dreams
Authors: Dawson Alexander S.
Published: January 2021

Mexicans have long dreamt of the First World, and in recent times it has landed with a thud. Under the guise of globalization, Mexico opened its borders, reformed its political system, and transformed its economy. The impacts have been paradoxical.

In First World Dreams Alexander Dawson explores the contradictions and challenges which Mexico has experienced in embracing the market so wholeheartedly. A vibrant civil society is marred by human rights abuses and violent rebellion. Market reforms have produced a stable economy, economic growth and great fortunes, while devastating much of the countryside and crippling domestic producers. Mexico is today one of the world's largest exporting nations, yet has a perpetually negative trade balance. It is in a constant state of becoming a democracy, a nation where human rights are respected, a modern industrial nation, and a more violent, fragmented place where the chasms of wealth and poverty threaten to undo the dreams of modernity.
