Published: December 2019

In Morocco, “Zizyphus lotusL.” is one of the most widely and traditionally used plant species to treat various diseases, including liver disorders. The present study was conducted to evaluate the aqueous extract ofZizyphus lotusL. fruit against carbon tetrachloride- (CCL4-) induced liver damage in Wistar rats. The animals were daily treated with the aqueous extract ofZizyphus lotusL. fruit using two doses separately 200 and 400 mg/kg body weight for 14 days. CCL4was injected intraperitoneally (1 ml/kg body weight) at two times, 7thand 14thdays. At the end of the treatment, rats were sacrificed, and the blood was collected for the assessment of biochemical parameters. Moreover, the body weight as well as liver weight was determined. The injection of CCl4to the rats induced various alterations such as the increase of relative liver weight, serum alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, total bilirubin, direct bilirubin, triglycerides, very low-density lipoproteins, total cholesterol (slight increase), creatinine, urea, uric acid, and malondialdehyde. On the contrary, the effects of CCL4lead to the reduction in serum levels of high-density lipoprotein. However, the daily administration of the aqueous extract ofZizyphus lotusL. fruit to the injected rats with CCL4restored this abnormal variation in these biochemical parameters to normal values. Based on the results obtained in this study, it seems that the aqueous extract ofZizyphus lotusL. fruit has an hepatoprotective effect against hepatic lesions induced by CCL4in rats.
Isomorphisms from Extremely Regular Subspaces of C0K into C0S,X Spaces
Authors: Cerpa-Torres Manuel Felipe , Rincón-Villamizar Michael A.
Published: December 2019

For a locally compact Hausdorff space K and a Banach space X, let C0K,X be the Banach space of all X-valued continuous functions defined on K, which vanish at infinite provided with the sup norm. If X is ℝ, we denote C0K,X as C0K. If AK be an extremely regular subspace of C0K and T:AK⟶C0S,X is an into isomorphism, what can be said about the set-theoretical or topological properties of K and S? Answering the question, we will prove that if X contains no copy of c0, then the cardinality of K is less than that of S. Moreover, if TT−1<3 and AK is also a subalgebra of C0K, the cardinality of the αth derivative of K is less than that of the αth derivative of S, for each ordinal α. Finally, if λX>1 and TT−1<λX, then K is a continuous image of a subspace of S. Here, λX is the geometrical parameter introduced by Jarosz in 1989: λX=infmaxx+λy:λ=1:x=y=1. As a consequence, we improve classical results about into isomorphisms from extremely regular subspaces already obtained by Cengiz.

Published: December 2019

Cavernous hemangiomas are endothelial tumors that rarely affect the adrenal glands. Most of these tumors remain silent and are incidentally found on abdominal imaging. Hardly ever, these tumors are endocrinologically functional. They may present as vague abdominal pain. Surgical resection remains the mainstay for large masses. In this paper, we are presenting a case of adrenal cavernous hemangioma in a 83-year-old male patient who initially presented for workup of vague abdominal and bilateral flank pain. A computed tomography scan of the abdomen showed an 8 cm right adrenal adenoma which was metabolically nonfunctional. The mass was completely resected through an open subcostal incision, with no encountered postoperative complications. A highlight of all published cases of adrenal hemangiomas since 1955 is also presented and reviewed.

Published: December 2019

Burnout is defined as an occupational phenomenon linked to chronic workplace stress that has not been successfully managed and included among the factors influencing health status or contact with health services. Although several studies were performed for assessing this phenomenon, there is a lack of data on the prevalence of burnout and associated predictors, due to different definitions of the syndrome and heterogeneity of assessment methods. One of the well-known evidences on burnout is related to the highest risk professions, which include policemen, firemen, teachers, psychologists, medical students, nurses, physicians, and other health professionals, such as pharmacists. Objective. The aims of the present study were to (1) assess the occurrence of burnout syndrome among a sample of pharmacists employed in public and private pharmacies located in Rome province (Latium Region; central Italy); (2) evaluate the role of some potential predictors for the development of the syndrome. Materials and Methods. A questionnaire elaborated ad hoc was administered online to 2,000 members of the Association of Professional Pharmacists of Rome and its province and employed in public or private pharmacies. The questionnaire included the 14-item Shirom–Melamed Burnout Measure (SMBM) tool and questions on demographic characteristics and working conditions. Results. Physical exhaustion was the burnout dimension with the highest score; besides, approximately 11% of the studied pharmacists were categorized as having clinically relevant burnout levels (≥4.40). Several of the investigated variables significantly influenced the single burnout dimensions at the univariate analyses; multivariate analyses demonstrated that alcohol consumption and workplace location have a significant independent role on the overall SMBM index, while working time significantly influences clinically relevant burnout level. Conclusions. The results revealed that pharmacists are at risk of burnout, and thus, it is necessary to perform specific preventive intervention for managing this occupational threat.
DMCNN: A Deep Multiscale Convolutional Neural Network Model for Medical Image Segmentation
Authors: Teng Lin , Li Hang , Karim Shahid
Published: December 2019

Medical image segmentation is one of the hot issues in the related area of image processing. Precise segmentation for medical images is a vital guarantee for follow-up treatment. At present, however, low gray contrast and blurred tissue boundaries are common in medical images, and the segmentation accuracy of medical images cannot be effectively improved. Especially, deep learning methods need more training samples, which lead to time-consuming process. Therefore, we propose a novelty model for medical image segmentation based on deep multiscale convolutional neural network (CNN) in this article. First, we extract the region of interest from the raw medical images. Then, data augmentation is operated to acquire more training datasets. Our proposed method contains three models: encoder, U-net, and decoder. Encoder is mainly responsible for feature extraction of 2D image slice. The U-net cascades the features of each block of the encoder with those obtained by deconvolution in the decoder under different scales. The decoding is mainly responsible for the upsampling of the feature graph after feature extraction of each group. Simulation results show that the new method can boost the segmentation accuracy. And, it has strong robustness compared with other segmentation methods.
The Effect of Teachers’ Dress on Students’ Attitude and Students’ Learning: Higher Education View
Authors: Kashem Mohammad Abul
Published: December 2019

Dress which has had the influences on the perceptions of viewers whether students or outsiders, is more than just a wearing. At first instance, the outlook imposes a very positive expectation subjective to the likeliness and behavior pattern of the students. A positive impression ultimately imposes a positive atmosphere of learning toward the students’ mind. How the dress usually influences the learning of students depending on students’ attitude is the prime concern of this study. For validation of ideas, 405 respondents' judgments were justified from eight private universities of Bangladesh through Confirmatory Factor Analysis and Structural Equation Modeling. Depending on their relationship, three hypotheses such as students’ attitude to students’ learning, dress to students’ attitude, and finally dress to students’ learning were strongly supported, with path coefficients of 0.483, 0.533, and 0.425, respectively. These rationalizations finally signify the new mood of appearance in student learning paradigms in context to influential role-playing foundation of teachers into the mind of learners.

Published: December 2019

This paper proposes the implementation of simple boost circuit incorporated in inverter fed Brushless DC (BLDC) motor drive to boost the performance of torque. BLDC motor becoming subtle because of its performance. But the motor performance is inferior due to the voltage source inverter fed operation of BLDC motor which initiates torque ripple during commutation. Here the usage of Switched Boost Inverter (SBI) which minimizes the storage elements (passive elements), more active element and introduces shoot through mode during commutation as like Z-source inverter.  The analyses of three phase switched boost inverter fed BLDC motor drive have been carried out. The performance of torque almost depends on the stator phase current of the motor. In BLDC motor during commutation interval, one phase loss its exact stator phase current hence it instigate ripple on the torque. The proposed method focuses two intentions to reduce the torque ripple. The first intension is to operate the BLDC motor at 180ᵒ electrical conduction mode, second intension is to introduce the shoot through interval to boost the dc link voltage so as to maintain the stator phase current control which leads to suppress the torque ripple during commutation.  The validation of the proposed SBI based BLDC motor control is demonstrated both by MATLAB/Simulink and Field programmable gate array (FPGA) controller-SPARRTAN III processor. The experimental results of the developed SBI based BLDC motor drive is working over a wide speed range with minimal torque ripple compared to the normal PWM based inverter control.

Published: December 2019

This work shows the design and tuning procedure of a discrete PID controller for regulating buck boost converter circuits. The buck boost converter model is implemented using Simscape Matlab library without having to derive a complex mathematical model. A new tuning process of digital PID controllers based on identification data has been proposed. Simulation results are introduced to examine the potentials of the designed controller in power electronic applications and validate the capability and stability of the controller under supply and load perturbations. Despite controller linearity, the new approach has proved to be successful even with highly nonlinear systems. The proposed controller has succeeded in rejecting all the disturbances effectively and maintaining a constant output voltage from the regulator.

Published: December 2019

Limitations of DC injection into the AC network is an important operational requirement for grid connected photovoltaic systems. There is one way to ensure that this issue needs a power transformer as a connection to the AC network. However, this solution adds cost, volume, mass, and power losses. Ideally there shouldn't be any DC at the output of the inverter, but practically, a small amount of DC current is present. Therefore, in this paper there are techniques for the DC offset elimination are proposed. Some have drawbacks which was treated by another technique. Also there are best solutions for eliminating DC offset as in section 17, and 18 as it explains how to reduce the DC offset in a transformerless operation with reducing the power losses, mass and the cost effect.

Authors: Syakir Adli Mohd , Mohamad Hanif Noor Hazrin Hany , Toha Tohara Siti Fauziah
Published: December 2019

This paper presents a control scheme for speed control system in brushless dc (BLDC) motor to be utilized for electric motorbike. While conventional motorbikes require engine and fuel, electric motorbikes require DC motor and battery pack in order to be powered up. The limitation with battery pack is that it will need to be recharged after a certain period and distance. As the recharging process is time consuming, a PID controller is designed to maintain the speed of the motor at its optimum state, thus ensuring a longer lasting battery time (until the next charge). The controller is designed to track variations of speed references and stabilizes the output speed accordingly. The simulation results conducted in MATLAB/SIMULINK® shows that the motor, equipped with the PID controller was able to track the reference speed in 7.8x10-2 milliseconds with no overshoot.  The result shows optimistic possibility that the proposed controller can be used to maintain the speed of the motor at its optimum speed.
Competência midiática e cultura de fãs

Published: December 2019

As fan fictions estimulam o entendimento crítico do fã, uma vez que as histórias propiciam a leitura crítica e criativa dos universos ficcionais, conforme discute Jenkins (2012). A partir deste contexto, o artigo reflete sobre o diálogo entre a competência midiática e o Twittertainment na social TV brasileira. Esta categoria de fan fiction, que é produzida pelos telespectadores interagentes ávidos de maneira síncrona à exibição da programação, imbrica dois desdobramentos da competência midiática, o Twitter literacy e o remix literacy. Para isso, são analisados os perfis criados no Twitter pelos fãs das telenovelas da Rede Globo, cujos conteúdos remixam distintos contextos e linguagens, propagam o universo ficcional e atualizam discussões sobre questões sociais e políticas.
Um conceito de ouvinte expandido
Authors: Ferraz Nivaldo
Published: December 2019

Do que pensaram autores da República de Weimar (Bertolt Brecht, Walter Benjamin e Rudolf Arnheim) sobre a relação do rádio com seus ouvintes, passando pela consideração dos estudos culturais ingleses e do conceito de estrutura do sentir de Raymond Williams, pode-se constituir um caminho para a discussão de como o ouvinte experimenta a interatividade com o rádio e com o som nestes dias. A despeito da amplitude atual da participação do ouvinte na programação, ela não chega a contemplar os ideais, principalmente, de Benjamin e Brecht, sendo que, este último, em sua “Teoria do rádio”, preconiza um ouvinte que fala na mesma medida do apresentador. O estudo mostra que é possível dimensionar o ouvinte atual como ouvinte expandido, uma extensão ao conceito de rádio expandido de Marcelo Kischinhevsky.
Cartas para um ladrão de livros
Authors: Paganotti Ivan
Published: December 2019

O artigo analisa a polêmica ao redor do documentário Cartas para um ladrão de livros. Ao expor o furto de obras raras de acervos públicos brasileiros, seus produtores sofreram ameaças de processos judiciais, o que levou à autocensura do filme. O trabalho avalia essa irônica contradição entre o retrato de um personagem perseguido pela justiça por roubar documentos públicos e vendê-los para colecionadores privados, e a ameaça judicial contra o documentário que denuncia a privatização da memória coletiva. Para isso, será analisada também a repercussão dessa denúncia automutilada: poucos meses após seu lançamento, o filme atraiu a atenção de repórteres da imprensa, que acabaram revelando nomes antes censurados de compradores das obras.

Mudaram as Princesas?
Authors: Tondato Marcia Perencin , Vilaça Maria Giselda
Published: December 2019

Neste artigo discutimos as ressignificações das Princesas Disney em sites de redes sociais, em que perfis são criados de acordo com interesses diversos. O ponto de partida é o imaginário do feminino surgido nos contos clássicos do século XIX (Grimm, Andersen, La Fontaine, Perrault e Lewis Carroll) e originalmente não escritos para o universo infantil, mas metamorfoseados pela indústria da fantasia na forma de uma diversidade de produtos. O debate tem origem na mudança ainda lenta percebida no perfil das princesas nos últimos dez anos: de jovens indefesas, sonhadoras e esperando pelo príncipe encantado a pequenas heroínas idealistas que lutam por uma causa. O objetivo é explorar essas ressignificações, tomando como base perfis de princesas no Facebook, com o intuito de analisar os elementos constituintes em busca de sinalizadores da representação da identidade feminina na contemporaneidade.

Published: December 2019

O objetivo do artigo é apresentar e analisar a reflexão crítica de Roberto Schwarz sobre os impasses do processo de formação nacional, em particular o modo como esta se apresenta em alguns dos seus ensaios publicados nas últimas três décadas, a partir da virada para os anos 1990. À época, em meio às transformações pelas quais passavam o Brasil e o mundo, Schwarz radicalizou e ampliou o escopo da negatividade já presente nas suas reflexões precedentes, contrapondo-se às visões “positivas” da questão nacional, inscritas no horizonte da modernização capitalista. A hipótese central é a de que essa “negatividade periférica” pode ser apreendida por meio da compreensão do modelo de crítica (ensaística) cultivado pelo “último” Schwarz, modelo que define a sua posição singular no cenário intelectual brasileiro.

Published: December 2019

Os Stocks Monte Pedral, Boa Esperança, Santa Maria, Niterói e Bom Jardim situam-se na parte Norte do Sistema Orogênico Sergipano. Esses cinco corpos são constituídos por: álcali-feldspato sienito e quartzo álcali-feldspato sienito (Monte Pedral); quartzo álcali-feldspato sienito e álcali-feldspato granito (Boa Esperança); granito (Santa Maria); monzogranito, quartzo monzonito e quartzo monzodiorito (Niterói); granito, quartzo monzonito, granodiorito, quartzo monzodiorito e diorito (Bom Jardim). Essas rochas são porfiríticas, com megacristais de feldspato alcalino rico em zoneamentos oscilatórios. A ocorrência de megacristais de feldspato alcalino com zoneamento composicional bem marcado e enclaves máficos é uma feição que distingue esse magmatismo daqueles de outras suítes intrusivas do Domínio Canindé. Os Stocks Monte Pedral e Boa Esperança correspondem a um magmatismo hipersolvus, enquanto os demais Stocks (Bom Jardim, Niterói e Santa Maria) representam magmatismo subsolvus. A idade U-PbShrimp de 611 ± 4 Ma obtida para o Stock Santa Maria permite correlacioná-lo ao plutonismo shoshonítico mais antigo no Sul da Província Borborema. A mica marrom nas rochas corresponde à biotita e flogopita e indica afinidade orogênica para este plutonismo. A Mg-hornblenda e a tschermakita são os anfibólios primários nestas rochas, os quais cristalizaram-se em condições oxidantes e em profundidades que variam de 12 (3 kbar) a 26 (7 kbar) km. Dados geoquímicos revelam que os magmas responsáveis por formarem os stocks estudados pertencem a suítes shoshoníticas e evoluem por cristalização fracionada, tendo contribuição de material mantélico, além de exibirem assinatura geoquímica (enriquecimento em Elementos Terras Raras Leves), em relação aos pesados, e anomalias negativas em Ta, Nb, P, Sr e Eu, características de magmas associados à subducção.
Do “ângulo reto” aos dispositivos poético-visuais do urbanismo moderno
Authors: Benoit Alexandre
Published: December 2019

Com este artigo objetiva-se analisar como a noção de ângulo reto, no interior do universo criativo de Le Corbusier, assume distintos aspectos até se cristalizar em um importante conceito de seu pensamento sobre a relação entre edifício, cidade e paisagem. Partindo do livro autobiográfico O poema do ângulo reto (Le poème de l’angle droit ,1951-55), busca-se traçar pontes entre alguns versos e imagens dessa obra e trechos de seus escritos, conferências e desenhos das viagens entre 1911 e 1936, abordando sobretudo seu périplo pelo leste europeu até Atenas e aquelas duas viagens à América do Sul, onde sua relação mais profícua se deu no Rio de Janeiro. Da aproximação desse material com algumas obras emblemáticas do período purista de sua pintura, como A lareira (La chaminée, 1918), evidencia-se como o conceito em questão tem uma dimensão eminentemente visual. Com este panorama, a investigação busca apresentar um ângulo reto dividido entre a técnica impositora e a liberdade total de criação, expressando os dilemas não resolvidos do próprio arquiteto.
A construção de um discurso de alteridade e o papel social do design por meio da disciplina “O Design Posto em Questão”
Authors: Ribeiro dos Santos Luciene , Montuori Bruna Ferreira , Dozzi Gutierrez Gabriel , Palma de Carvalho Amanda Beatriz , Mattos Nicoletti Viviane
Published: December 2019

O presente artigo tem como objetivo apresentar o impacto social que a disciplina O Design Posto em Questão, ministrada pela Professora Dra. Maria Cecilia Loschiavo dos Santos no curso de pós-graduação em Design da FAU-USP, tem provocado no desenvolvimento de pesquisas de mestrado e doutorado e em projetos de pesquisa que visam o processo seletivo de pós-graduação − por meio da construção de uma perspectiva de alteridade e de relevância dada ao papel social do design −, durante as discussões e debates realizados em sala. Este artigo, escrito por alunos que participaram da disciplina, e que recentemente defenderam suas pesquisas de mestrado na área de Design e Arquitetura, pretende abordar a bibliografia selecionada para leitura, com menção a alguns seminários e debates ocorridos em aula, a fim de demonstrar como o curso tem auxiliado no reconhecimento do papel social do design em pesquisas de diferentes temas, desconstruindo, ao mesmo tempo, conceitos e questões sociais relativas a este campo do conhecimento, em busca de um olhar de valorização e recognição sobre o outro, para quem se destina a pesquisa.
A errância como potência em Dom Quixote
Authors: Pedrosa Gabriel
Published: December 2019

A partir da recusa de Dom Quixote em buscar cortes ou cidades, explicitada em um diálogo com Sancho Pança no 21º capítulo da primeira parte do livro de Cervantes, este artigo reflete sobre sua errância, como perambulação pelo descampado, mas também como comportamento não orientado por funções e como identidade em constante invenção. Esta reflexão, com as várias referências filosóficas e literárias que levanta, encontra não uma peculiaridade do cavaleiro manchego, mas uma tensão permanente em nossa cultura, propondo o Quixote como uma reversão do modo a que estamos habituados a lê-la.
O novo ambiente de trabalho: diversidade ambiental e flexibilidade do espaço
Authors: Gonçalves Joana Carla Soares
Published: December 2019

O impacto ambiental e os problemas de conforto e saúde nos edifícios da caixa de vidro inspiraram, no início da década de 1990, novos paradigmas arquitetônicos para a tipologia do edifício de escritório. Porém, as considerações para com à ventilação como iluminação natural eram marcantes já nas obras ícones das primeiras décadas do modernismo no Brasil e no exterior. Mas foi apenas a partir das duas últimas décadas do século XX que o reconhecimento dos efeitos de ambientes mais informais na satisfação e produtividade dos ocupantes levou à inserção de espaços de transição no projeto de escritórios. Estas mudanças arquitetônicas fazem parte de uma noção mais flexível de conforto ambiental. Paralelamente, a evolução das tecnologias de informação, somada ao surgimento da chamada economia do conhecimento, introduziu novas tendências para as rotinas de ocupação do ambiente de trabalho, que valorizam espaços qualificados pela vegetação, áreas informais, comunicação visual entre interior e exterior e luz natural, resultando em ambientes mais abertos ao exterior. A revisão crítica de teorias e estudos de caso sugere um ambiente de trabalho em que espaços alternativos como varandas e jardins tornam-se espaços potenciais para diversas atividades que constituem os novos escritórios do século XXI.
A comparative analysis of hair morphology of wild and domestic ungulate prey species of Leopard Panthera pardus fusca (Mammalia: Carnivora: Felidae) from Goa, India

Guard hairs were collected from four live domesticated ungulate species and shed guard hairs of six wild ungulate species from zoo captive animals from five individuals each.  Photographic reference was prepared showing analytic features of hair characteristics.  Study results were analysed and cuticle and medulla patterns were identified along with pigmentation features from the literature available for wild and domestic ungulates from India and abroad.  Clear and easily distinguishable morphological characters of hair medulla and cuticle were used in the present study.  Scat analysis of big cats used in this study is easy, speedy and efficient which can be used in routine investigations related to wildlife, crime forensics as well as human animal conflicts by studying carnivore feeding habits.  In a majority of the animal species, the distal part of the hair showed maximum variation from the rest of the hair portions.  The cuticle scales were imbricate in all tested animals.  Scale position in almost all the tested animals was transversal except in goat (proximal part and medial part) and mouse deer (Distal part).  Majority of the species showed smooth margins at proximal and medial part.  Whereas the distal part scale margin was crenate and rippled in appearance the proximal part and medial part of hair of the majority of sampled animals showed a regular wave -type scale pattern whereas the distal part of hair showed irregular wave-type scale pattern in dominance.  The composition of the medulla was multicellular in all the sampled deer species.  Only the cow calf’s hair medulla was unicellular and uniseriate in appearance.  A comparison of the hair of the domestic pig with that of the wild boar and gaur hair with that of cow calf and buffalo calf hair was made for the first time in the present study. Similarly goat hair morphology can also be differentiated from other cervids in this study.  Medulla and cuticle characters in combination with each other can help differentiate wild ungulate species from the domestic ones since these wild ungulate species are frequently involved in hunting crime investigations.  Therefore, the photographic reference presented in this study can be used in wildlife forensic science as well as predator diet analysis as an appropriate reference for prey species identification.
The Politics and Economics of the U.S.-China Trade War
Authors: Swenson Deborah L. , Woo Wing Thye
Published: December 2019

The United States declared trade war after substantial defections from the internationalist (in geo-strategy and economics) lobby in U.S. politics to a new coalition between conflict-is-inevitable activists and anti-globalization proponents. Many internationalist businesses changed sides after experiencing disappointments on economic fronts including China's non-compliance with some of its World Trade Organization (WTO) obligations, China's acquisition of foreign technology at lower-than-expected prices, and the serious inadequacies in the WTO's governance of global trade. Many of the disillusioned internationalists have given too much weight to the contribution of globalization to negative developments in the U.S. labor market, and too little weight to the role of powerful capital-biased technological changes and to the inadequacies of state-provided programs for social insurance and human capital formation. Resolution of the trade war and prevention of its frequent occurrence will become more likely when (a) China adopts much greater reciprocity in its economic engagement with the advanced countries despite its status as a developing country under WTO rules; and (b) the United States stops equating geo-strategic competition with economic competition, recognizes that economic dynamism and economic resilience comes from strengthening indigenous innovation capability rather than from holding China back technologically, and institutes social programs to significantly reduce the trauma that is created by frequent job changes. Deep reform of the WTO is urgently needed but is unlikely to happen in the medium run. For the medium run, the United States should mobilize country cooperation in regional settings (like the Trans-Pacific Partnership [TPP]) to introduce policy innovations to serve as templates for a re-designed WTO architecture, and to harness collective market power to be used in future negotiations on WTO reform.
Fighting Violence Against Women: Laws, Norms & Challenges Ahead
Authors: Htun Mala , Jensenius Francesca R.
Published: December 2019

In the 1990s and 2000s, pressure from feminist movements and allies succeeded in pushing scores of states to reform their laws to prevent and punish violence against women (VAW). Even in states with progressive legislation, however, activists face challenges to induce citizens to comply with the law, compel state authorities to enforce the law, and ensure the adequate allocation of resources for social support services. In this essay, we take stock of legislative developments related to VAW around the world, with a focus on the variation in approaches toward intimate partner violence and sexual harassment. We analyze efforts to align behavior with progressive legislation, and end with a discussion of the balance activists must strike between fighting VAW aggressively with the carceral and social support dimensions of state power, while exercising some restraint to avoid the potentially counterproductive effects of state action.
Women, Power & Leadership
Authors: Keohane Nannerl O.
Published: December 2019

Many more women provide visible leadership today than ever before. Opening up higher education for women and winning the battle for suffrage brought new opportunities, along with widespread availability of labor-saving devices and the discovery and legalization of reliable, safe methods of birth control. Despite these developments, women ambitious for leadership still face formidable obstacles: primary if not sole responsibility for childcare and homemaking; the lack of family-friendly policies in most workplaces; gender stereotypes perpetuated in popular culture; and in some parts of the world, laws and practices that deny women education or opportunities outside the home. Some observers believe that only a few women want to hold significant, demanding leadership posts; but there is ample evidence on the other side of this debate, some of it documented in this volume. Historic tensions between feminism and power remain to be resolved by creative theorizing and shrewd, strategic activism. We cannot know whether women are “naturally” interested in top leadership posts until they can attain such positions without making personal and family sacrifices radically disproportionate to those faced by men.
