Automated classification of mitotic catastrophe by use of the centromere fragmentation morphology
Authors: Roy Kaushiki , Lewis Cody W. , Chan Gordon K. , Bhattacharjee Debotosh
Published: September 2020

Mitotic catastrophe is a common mode of tumor cell death. Cancer cells with a defective cell-cycle checkpoint often enter mitosis with damaged or under replicated chromosomes following genotoxic treatment. Premature condensation of the under-replicated (or damaged) chromosomes results in double-stranded DNA breaks at the centromere (centromere fragmentation). Centromere fragmentation is a morphological marker of mitotic catastrophe and is distinguished by the clustering of centromeres away from the chromosomes. We present an automated 2-step system for segmentation of cells exhibiting centromere fragmentation. The first step segments individual cells from clumps. We added two new terms, weighted local repelling term (WLRt) and weighted gradient term (WGt), in the energy functional of the traditional Chan–Vese based level set method. WLRt was used to generate a repelling force when contours of adjacent cells merged and then penalized the overlap. WGt enhances gradients between overlapping cells. The second step consists of a new algorithm, SBaN (shape-based analysis of each nucleus), which extracts features like circularity, major-axis length, minor-axis length, area, and eccentricity from each chromosome to identify cells with centromere fragmentation. The performance of SBaN algorithm for centromere fragmentation detection was statistically evaluated and the results were robust.

Published: September 2020

Based on Monte Carlo simulation, the magnetic properties of a mixed spin-1 and spin-3/2 Ising superlattice with alternate layers are studied. The effects of interlayer coupling and external magnetic field on the compensation behavior and hysteresis properties for the ferrimagnetic superlattice are investigated. The occurrence of a compensation point is found to be greatly affected by the interlayer coupling. In particular, various multiple hysteresis loops can be observed under certain system parameters. The calculated results agree well with available experimental and theoretical works.
Soliton solutions to the nonlocal non-isospectral nonlinear Schrödinger equation
Authors: Feng Wei , Zhao Song-Lin
Published: September 2020

In this paper we study the nonlocal reductions for the non-isospectral Ablowitz-Kaup-Newell-Segur equation. By imposing the real and complex nonlocal reductions on the non-isospectral Ablowitz-Kaup-Newell-Segur equation, we derive two types of nonlocal non-isospectral nonlinear Schrödinger equations, in which one is real nonlocal non-isospectral nonlinear Schrödinger equation and the other is complex nonlocal non-isospectral nonlinear Schrödinger equation. Of both of these two equations, there are the reverse time nonlocal type and the reverse space nonlocal type. Soliton solutions in terms of double Wronskian to the reduced equations are obtained by imposing constraint conditions on the double Wronskian solutions of the non-isospectral Ablowitz-Kaup-Newell-Segur equation. Dynamics of the one-soliton solutions are analyzed and illustrated by asymptotic analysis.

While attention has always been prized above money, few people have had the means to attract it to themselves. But the new digital economy has provided everyone with a loudspeaker; thus efforts at getting noticed have rapidly escalated in global society. The attention economy focuses on the mechanisms that mediate the allocation of this scarce entity. Social networks and big data play a role in determining what is noticed and acted upon.
Engaging Learners in Online Environments Utilizing Universal Design for Learning Principles
Authors: Hollingshead Aleksandra , Carr-Chellman Davin
Published: September 2020

Learner engagement in any instructional environment, including online, is critical to ensuring meaningful learning outcomes. Researchers discuss engagement as a complex construct consisting of emotional, cognitive, and behavioral domains. In e-learning, student engagement is difficult to achieve. Universal Design for Learning (UDL) is an instructional design framework focused on overcoming barriers to learning and providing learners with multiple ways to engage, receive instruction, and express learning. This framework is based on a premise of variability of all learners and designing learning that is flexible and systematically planned. This manuscript provides background information on UDL alongside practical strategies for planning e-instruction that is engaging and aligned with UDL principles.

Genomic Approaches to Drug Resistance in Malaria
Authors: Rocamora Frances , Winzeler Elizabeth A.
Published: September 2020

Although the last two decades have seen a substantial decline in malaria incidence and mortality due to the use of insecticide-treated bed nets and artemisinin combination therapy, the threat of drug resistance is a constant obstacle to sustainable malaria control. Given that patients can die quickly from this disease, public health officials and doctors need to understand whether drug resistance exists in the parasite population, as well as how prevalent it is so they can make informed decisions about treatment. As testing for drug efficacy before providing treatment to malaria patients is impractical, researchers need molecular markers of resistance that can be more readily tracked in parasite populations. To this end, much work has been done to unravel the genetic underpinnings of drug resistance in Plasmodium falciparum. The aim of this review is to provide a broad overview of common genomic approaches that have been used to discover the alleles that drive drug response phenotypes in the most lethal human malaria parasite.

Published: September 2020

Electrochemical biosensors have attracted a tremendous attention for many researchers recently due to its facile synthesis process, tunability easiness by tailoring the material properties or composition, and wide range of biological analyte types detection. To obtain an excellent electrochemical biosensor performance, a material that facilitates fast electron transfer, large surface area, excellent electrocatalytic activity, and abundant available sites for bioconjugation is immensely needed. Metal-organic frameworks in the two-dimensional form (2D MOFs) provide all of the criteria needed as the sensing material for electrochemical biosensors application. However, the design and preparation of 2D MOFs, which have high stability and sensitivity as well as good selectivity for biological analyte detection, is still quite challenging. This review provides the recent studies and development of 2D MOFs as electrochemical biosensor. A detailed discussion about 2D MOFs structures, their synthesis strategy and control, 2D MOFs materials in electrochemical biosensor application, and the future challenges is thoroughly explained in this review. Hopefully, this review will also provide a new inspiration to advance future studies of 2D MOFs materials development as electrochemical biosensor.
Disparity in the effect of morphine on eupnea and gasping in anesthetized spontaneously breathing adult rats
Authors: Shoemaker Amanda , Steelman Kevin , Srbu Rebeka , Bell Harold J.
Published: September 2020

The goal of this study was to examine the effects of systemic morphine on the pattern and morphology of gasping breathing during respiratory autoresuscitation from transient anoxia. We hypothesized that systemic morphine levels sufficient to cause significant depression of eupnea would also cause depression of gasping breathing. Respiratory and cardiovascular variables were studied in 20 spontaneously breathing pentobarbital-anaesthetized adult male rats. Sham (saline) injections caused no significant change in resting respiratory or cardiovascular variables ( n = 10 rats). Morphine, on the other hand, caused significant depression of eupneic breathing, with ventilation and peak inspiratory flow decreased by ∼30–60%, depending on the background condition ( n = 10 rats). In contrast, morphine did not depress gasping breathing. Duration of primary apnea, time to restore eupnea, the number and amplitude of gasping breaths, average and maximum peak flows, and volume of gasping breaths were not significantly different postinjection in either condition. Blood pressures were all significantly lower following morphine injection at key time points in the process of autoresuscitation. Last, rate of successful recovery from anoxia was 80% in the morphine group (8/10 rats) compared with 100% (10/10 rats) in the sham group, postinjection. We conclude that the mechanisms and/or anatomic correlates underlying generation of gasping rhythm are distinct from those underlying eupnea, allowing gasping to remain robust to systemic morphine levels causing significant depression of eupnea. Morphine nevertheless decreases likelihood of recovery from transient anoxia, possibly as a result of decreased tissue perfusion pressures at critical time points during the process of respiratory autoresuscitation.
An Adaptive Particle Swarm Optimization Algorithm for Unconstrained Optimization
Authors: Qian Feng , Mahmoudi Mohammad Reza , Parvïn Hamïd , Pho Kim-Hung , Tuan Bui Anh
Published: September 2020

Conventional optimization methods are not efficient enough to solve many of the naturally complicated optimization problems. Thus, inspired by nature, metaheuristic algorithms can be utilized as a new kind of problem solvers in solution to these types of optimization problems. In this paper, an optimization algorithm is proposed which is capable of finding the expected quality of different locations and also tuning its exploration-exploitation dilemma to the location of an individual. A novel particle swarm optimization algorithm is presented which implements the conditioning learning behavior so that the particles are led to perform a natural conditioning behavior on an unconditioned motive. In the problem space, particles are classified into several categories so that if a particle lies within a low diversity category, it would have a tendency to move towards its best personal experience. But, if the particle’s category is with high diversity, it would have the tendency to move towards the global optimum of that category. The idea of the birds’ sensitivity to its flying space is also utilized to increase the particles’ speed in undesired spaces in order to leave those spaces as soon as possible. However, in desirable spaces, the particles’ velocity is reduced to provide a situation in which the particles have more time to explore their environment. In the proposed algorithm, the birds’ instinctive behavior is implemented to construct an initial population randomly or chaotically. Experiments provided to compare the proposed algorithm with the state-of-the-art methods show that our optimization algorithm is one of the most efficient and appropriate ones to solve the static optimization problems.

Published: September 2020

Burkitt lymphoma (BL) is a highly aggressive but potentially curable disease as long as adequately treated within due time. BL may occur primarily and exclusively in the bone marrow as a form of peripheral and extranodal disease. BL cases with isolated bone marrow involvement are challenging in regard to a prompt diagnostic process. We report a case of a sporadic extranodal subtype of isolated bone marrow BL in an 11-year-old boy. Bone marrow aspiration and biopsy, flow cytometry, and immunohistochemistry along with cytogenetics are compulsory in order to achieve the adequate diagnosis.
Permeability Characteristics of Coal after Supercritical CO2 Adsorption at Different Temperatures
Authors: Liu Xueying , Yu Jin , Wu Di , Xiao Xiaochun
Published: September 2020

CO2 storage in coal seams has become one effective method to reduce CO2 emission and help exploit coalbed methane (CBM). The permeability is a key parameter for CBM extraction. In deep coal seams (>800 m), CO2 exists in the supercritical state. In the present work, permeability tests were performed on briquettes before and after supercritical CO2 (SC-CO2) adsorption at various temperatures to investigate the effects of SC-CO2 adsorption on the permeability. Experimental results show that SC-CO2 adsorption leads to volumetric expansion and permeability augment. The permeability enhancement decreases continuously at 35°C, while it initially increases and reduces at pressures exceeding 9 or 10 MPa at 45 or 55°C, respectively. Besides, the permeability enhancement ratio shows a linear increase with the expansion. The research provides a basis for further research on the enhanced coalbed methane (ECBM) recovery.
Trapped Esophageal Stent in a Child: An Unusual Complication
Authors: Okumuş Mustafa
Published: September 2020

Background. Migration is the most frequent and well-known complication of self-expandable metal stents (SEMS). Most of the time, migrated stents are still in the esophagus and can be relocated or removed successfully through endoscopy. However, what can be done if the stent is stuck between two esophageal strictures? Herein, we present a child with a trapped esophageal stent. Method. A 2-year-old male patient with an esophageal stent which migrated and became stuck between two esophageal strictures was reported. Results. Proximal stricture was excised, and the stent was removed via a right thoracotomy. Balloon dilatation was applied to the distal stricture. The patient was discharged on the 17th postoperative day without any problem. Conclusions. Pediatric patients with an esophageal stent should be closely followed up during this period. Early detection of complications makes treatment easier. Otherwise, there may be no option other than surgical treatment, as in the patient presented here.

Authors: Shaikh Nissar , Nawaz Shoaib , Chanda Arshad , Nahid Seema , Zubair Muhmmad , Ummunnisa Firdous
Published: September 2020

Eclampsia is associated with high maternal and fetal morbidity and mortality. The mortality in eclampsia is reported to be secondary to cerebrovascular accidents, neurogenic pulmonary edema, or acute kidney injury leading to cardiac arrest. A rarely reported etiology is sudden cardiac arrest (SCA) immediately after the seizure activity. We report a case of morbidly obese multigravida, complicated into postnatal eclampsia developing postseizure SCA due to apnea. Case. A 35-year-old woman in 38 weeks of gestation presented to the women’s hospital emergency with hypertension and proteinuria and had lower section caesarean section under epidural anesthesia and required labetalol infusion. She developed convulsions in the 1st postoperative day, and she was started on magnesium sulphate therapy. After a few minutes, the patient had a 2nd episode of convulsions, apnea, cyanosis, and cardiac asystole requiring cardiopulmonary resuscitation and spontaneous circulation returned in 3 minutes. Her endotracheal intubation was difficult, but we succeeded in the 2nd attempt. She was sedated, ventilated, and required noradrenaline to maintain hemodynamics. Her ECG, echocardiogram, cardiac biomarkers, CT chest/brain, and serum magnesium levels were within normal range. The patient was weaned from vasopressor and ventilator by day 2 and extubated. She became awake; labetalol and magnesium sulphate infusions were stopped by day 3. The patient was transferred to the ward on day 5; from there she was discharged home on day 8 on oral labetalol. She was followed up in an outpatient clinic after 4 weeks and remained comfortable, and blood pressure was controlled with tablet labetalol and repeat echocardiogram was normal. Conclusion. Eclampsia patients can have apnea after seizures, progressing to SCA.
Pharmacologic Inhibition of Ezrin-Radixin-Moesin Phosphorylation is a Novel Therapeutic Strategy in Rhabdomyosarcoma
Authors: Proudfit Austin , Bhunia Nabanita , Pore Debasis , Parker Yvonne , Lindner Daniel , Gupta Neetu
Published: September 2020

Intermediate and high-risk rhabdomyosarcoma (RMS) patients have poor prognosis with available treatment options, highlighting a clear unmet need for identification of novel therapeutic strategies. Ezrin-radixin-moesin (ERM) family members are membrane-cytoskeleton linker proteins with well-defined roles in tumor metastasis, growth, and survival. ERM protein activity is regulated by dynamic changes in the phosphorylation at a conserved threonine residue in their C-terminal actin-binding domain. Interestingly, ERM family member, ezrin, has elevated expression in the RMS tissue. Despite this, the translational scope of targeting ERM family proteins in these tumors through pharmacological inhibition has never been considered. This study investigates the inhibition of ERM phosphorylation using a small molecule pharmacophore NSC668394 as a potential strategy against RMS. Upon in vitro treatment with NSC668394, RMS cells exhibit a dose-dependent decrease in cell viability and proliferation, with induction of caspase-3 cleavage and apoptosis. siRNA-mediated knockdown of individual ERM protein expression revealed that each regulates RMS survival to a different degree. In vivo administration of NSC668394 in RMS xenografts causes significant decrease in tumor growth, with no adverse effect on body weight. Collectively, this study highlights the importance of the active conformation of ERM proteins in RMS progression and survival and supports pharmacologic inhibition of these proteins as a novel therapeutic approach.
Prospective STAR-Guided Ablation in Persistent Atrial Fibrillation Using Sequential Mapping With Multipolar Catheters
Authors: Honarbakhsh Shohreh , Schilling Richard J. , Finlay Malcolm , Keating Emily , Hunter Ross J.
Published: September 2020

Background:

A novel stochastic trajectory analysis of ranked signals (STAR) mapping approach to guide atrial fibrillation (AF) ablation using basket catheters recently showed high rates of AF termination and subsequent freedom from AF.

Methods:

This study aimed to determine whether STAR mapping using sequential recordings from conventional pulmonary vein mapping catheters could achieve similar results. Patients with persistent AF<2 years were included. Following pulmonary vein isolation AF drivers (AFDs) were identified on sequential STAR maps created with PentaRay, IntellaMap Orion, or Advisor HD Grid catheters. Patients had a minimum of 10 multipolar recordings of 30 seconds each. These were processed in real-time and AFDs were targeted with ablation. An ablation response was defined as AF termination or cycle length slowing ≥30 ms.

Results:

Thirty patients were included (62.4±7.8 years old, AF duration 14.1±4.3 months) of which 3 had AF terminated on pulmonary vein isolation, leaving 27 patients that underwent STAR-guided AFD ablation. Eighty-three potential AFDs were identified (3.1±1.1 per patient) of which 70 were targeted with ablation (2.6±1.2 per patient). An ablation response was seen at 54 AFDs (77.1% of AFDs; 21 AF termination and 33 cycle length slowing) and occurred in all 27 patients. No complications occurred. At 17.3±10.1 months, 22 out of 27 (81.5%) patients undergoing STAR-guided ablation were free from AF/atrial tachycardia off antiarrhythmic drugs.

Conclusions:

STAR-guided AFD ablation through sequential mapping with a multipolar catheter effectively achieved an ablation response in all patients. AF terminated in a majority of patients, with a high freedom from AF/atrial tachycardia off antiarrhythmic drugs at long-term follow-up.

Guns and Violence: Weapon Instrumentality in New Orleans Homicide, 1920–1945
Authors: Adler Jeffrey S.
Published: September 2020

Criminologists, sociologists, and public-health scholars have devoted enormous attention to the role of firearms in violence, particularly regarding American homicide rates, but historians have been less inclined to examine the impact of firearms, especially their availability, on changing patterns of violence. Instead, legal and criminal-justice historians have emphasized the ways in which institutional, cultural, political, and social changes have fueled shifts in levels of murder. An analysis of the rich homicide case files and newspaper accounts of gun violence in early twentieth-century New Orleans, however, confirms the theory of “weapon instrumentality”—that homicide rates tend to soar whenever and wherever firearms abound and to decrease when guns are in shorter supply.
Shaping the Common Ground: State-Building, the Railway Network, and Regional Development in Finland
Authors: Alvarez-Palau Eduard J. , Martí-Henneberg Jordi
Published: September 2020

Transport infrastructure played a key role in redefining Finland’s economic geography. An empirical investigation involving new gis databases that combine data about railways, population, and administrative boundaries at the municipal level between 1870 and 2000 permits the identification of three main phases of railway expansion: The first phase was a concentration of railways around Helsinki; the second, the construction of a grid-based national railway network, which coincided with a spread of the population into rural areas; and the third, an expansion of the railway into local networks when Finland’s industry began to coalesce around metropolitan areas.
Resisting Clarity: Scandinavian Ambiguity in the ‘Unable or Unwilling’-Debate
Authors: Schack Marc
Published: September 2020

When conflict arose between Iraq, Iraq’s US-led allies, and the terrorist group isil in 2014, legal scholars paid close attention. Amid the fighting these scholars tried to determine if the States getting involved, including Denmark and Norway, did so on the basis of a belief in the validity of the ‘Unable or Unwilling’-doctrine of self-defence. While some States were clear on this matter, Denmark and Norway both seemed ambiguous and hesitant – and were therefore habitually deemed sceptics of the doctrine. This article demonstrates, however, that this conclusion cannot be sustained. This insight is put forward, firstly, to correct a misleading narrative about the ‘Unable or Unwilling’-doctrine, and, secondly, to caution against relying on State practice and statements when doing so tells an uneven story and leads to disconnects between what States do and what they say – especially when there are palpable political reasons for States to resist clarity.
Three new species of Scyracepon Tattersall, 1905 (Isopoda: Bopyridae) from Pacific islands, with comments on the rarity of bopyrids parasitizing brachyurans
Authors: AN JIANMEI , ZHENG WANRUI , LIANG JIELONG , PAULAY GUSTAV
Published: September 2020

Three new species of the bopyrid genus Scyracepon Tattersall, 1905 are described from crabs collected on Pacific Islands: Scyracepon polynesiensis n. sp. from the Society Islands, S. pseudoliomerae n. sp. from the Mariana Islands, and S. biglobosus n. sp. from the Line Islands. The first two were found infesting Xanthias lamarckii and Pseudoliomera sp. (Xanthidae), a new host family for species of Scyracepon, and the last was found parasitizing Schizophrys aspera (Majidae). Scyracepon now includes 11 species, all but one known from single collections, infesting 12 host species in 9 brachyuran families. The discovery of three new species, each rare, suggests that crab parasites are undersampled, and further suggests that the low relative diversity of bopyrids known from brachyurans may partly reflect this undersampling. Keys to all species of Scyracepon and to all 31 genera of Keponinae are provided.
Femoroacetabular Impingement Syndrome
Authors: Trigg Steven D. , Schroeder Jeremy D. , Hulsopple Chad
Published: September 2020

Femoroacetabular impingement (FAI) syndrome is one of the most rapidly evolving etiologies of hip pain. The 2016 Warwick Agreement consensus statement defined FAI syndrome as a triad of symptoms, signs, and radiographic findings. Cam morphology is more likely in athletes and is associated with repetitive hip loading in maximal flexion during adolescence. Much less is known about the development of pincer morphology. Physical therapy improves pain and function, justifying a trial before pursuing surgery. Musculoskeletal injections are utilized for FAI syndrome, but the evidence is limited. Arthroscopic surgery for FAI syndrome can correct the morphological changes and address the underlying soft tissue injuries. Recent studies evaluated reliable indicators of surgical outcomes, the most reliable of which is the presurgical presence of osteoarthritis. Recent studies demonstrate the efficacy of surgery, but with the risk of complication and no guarantee of a return to the same level of sport.

Chronic non-cancer pain management by nurses in specialist pain clinics
Authors: Fernández-Castillo Rafael-Jesús , Gil-García Eugenia , Vázquez-Santiago María-Soledad , Barrientos-Trigo Sergio
Published: September 2020

Background:

Chronic non-cancer pain (CNCP) is one of the major causes of disability globally, and patients who suffer from it are a complex population, which makes it difficult to provide effective care. Specialist pain clinics and nursing professionals in them are the main care providers, but there is little research conducted in this field.

Aim:

To explore the attitudes and knowledge of nurses working in specialist pain clinics regarding care of CNCP patients.

Methods:

Qualitative phenomenological approach. Sixteen semi-structured interviews were conducted in 2017 with nurses who worked in specialist pain clinics in six hospitals in southern Spain.

Results:

Data analysis led to the formation of two categories, ‘being trained and improving knowledge in CNCP’ and ‘the challenge of caring for patients with CNCP’, and five subcategories.

Conclusion:

The need for care in CNCP is not covered by nurses in all the areas it requires. Lack of time, staffing issues, and specific training in this area makes it difficult to provide care. However, some areas for improvement are proposed, such as psychological interventions, group workshops, continuous training, and multidisciplinary teams.

Investigating non-medical prescribers' awareness of compliance
Authors: Boulton Sonia , White Alison
Published: September 2020

This paper sought to investigate non-medical prescribers' awareness of compliance and what is required for them to be compliant when prescribing in an acute NHS trust. This was a quantitative pilot study using a survey technique with an online questionnaire. A purposive sample from 85 registered non-medical prescribers who were actively prescribing were invited to participate. Data analysis was restricted because of the limited number of respondents (n=14), making this a pilot study. Data were analysed using descriptive statistical analysis IBM SPSS 25 software. The majority (85.7%) of non-medical prescribers were shown to be compliant, highlighting 14.3% as non-compliant. Furthermore, 28% prescribed outside of their personal formulary, which is in breach of the non-medical prescribers' trust policy. A further 85% participated in continuous professional development and 72% requested regular continuous professional development. Despite the majority being compliant with the non-medical prescribers' policy, 14.3% were not. This clearly has implications for patient safety and practitioner professionalism, in terms of responsibility and accountability. Although limited by small respondent size, the findings highlight the need for further research to inform recommendations for practice.
Modeling of the Crosstalk Phenomenon for Electro-Magnetic Systems by Bilateral Coupling of DAEs and PDEs
Authors: Niroomand Rad Helia , Steinbrecher Andreas
Published: September 2020

Modeling of the electro-magnetic disturbances between electrical elements which are sitting in an electro-magnetic system, the so-called crosstalk phenomenon, may lead to partial differential-algebraic equations.
In this poster, we propose a new modeling approach to describe the crosstalk phenomenon for electro-magnetic systems, and in particular, in electrical circuits by bilateral coupling of two sets of equations. The first set is a set of differential-algebraic equations (DAEs), the so-called circuit equations i.e. the Kirchhoff current law as well as constitutive laws of the inductors and the voltage sources and presented in our model in the framework of modified nodal analysis. The second set is the set of partial differential equations (PDEs), the so-called non-stationary Maxwell equations, modeling the induction of the electro-magnteic disturbances. Considering these two sets of equations as input-output subsystems, the bilateral coupling approach connects the output of one subsystem to the input of the other subsystem and conversely, via coupling and re-coupling relations. These relations, which are in principle physical constitutive laws, are introduced in our model by suitable operator structures. The coupling of these two sets of equations leads to a set of partial differential-algebraic equations as the model equations for the crosstalk phenomenon in electrical circuits.

Renda básica universal como programa para um novo reformismo: argumento a partir do caso brasileiro recente de conflito distributivo capital/trabalho
Authors: Santos Queiroz Pedro Henrique
Published: September 2020

O texto defende a pertinência do projeto de renda básica universal como horizonte normativo e eixo estratégico para uma ação política moderada de "reformismo forte" (André Singer) ou radical de "reformismo revolucionário" (André Gorz). O diálogo com a literatura disponível sobre renda básica universal é feito a partir de uma leitura da crise final do governo Dilma Rousseff como expressão dos limites do programa reformista fraco de "cidadania salarial" (Robert Castel). Conclui-se pelas vantagens do programa de renda básica universal em termos de capacidade de formulação clara de projetos, discursos de convencimento e orientação estratégica para a ação, seja de uma política reformista forte de redução rápida da pobreza ou reformista revolucionária de transição pós-capitalista.

RESUMEN

Contexto: La gran cantidad de Residuos de Construcción y Demolición (RCD) que se genera, se ha convertido en un problema a nivel Mundial. Por esta razón, la legislación en Colombia busca orientar su adecuada gestión y promover el aprovechamiento de estos.

Metodología: En esta investigación se plantea una alternativa para la elaboración del plan de gestión integral basada en un análisis de la legislación nacional y local de las ciudades que están a la vanguardia en el manejo de los RCD en Colombia.  Basado en este análisis se estudiaron y analizaron las condiciones y características de una ciudad intermedia como lo es Barranquilla para plantear una alternativa integral para el manejo de estos residuos (gestión y tratamiento).

Resultados: Se identificaron acorde con sus condiciones los aspectos de prevención, almacenamiento, recolección, transporte, aprovechamiento y disposición final a tener en cuenta dentro del plan de gestión integral de RCD más adecuado para la ciudad de Barranquilla y se planteó un esquema planta de tratamiento que se considera más adecuado en su manejo.

Conclusiones: Barranquilla requiere un ajuste rápido a su modelo de gestión de RCD, dada su alta tasa de desarrollo durante los últimos años. Se reconoció para esta ciudad que la separación en la fuente y el uso son fundamentales en el modelo requerido para lograr un proceso de gestión sostenible. Además, se identificaron debilidades en el sistema de gestión actual, asociadas con el uso de un modelo de economía lineal, por lo tanto, se propone un modelo de gestión basado en los principios de la economía circular.
Intuición colectiva y estadísticas alternativas para acertar

Contexto: El mundo varía rápidamente en el Antropoceno por sistemas socioecológicos sensibles y retroalimentadores. América Latina evidencia distancias grandes entre estadísticas y realidades. Se hacen necesarias mejores herramientas para evaluación y predicción que ofrezcan alternativas esperanzadoras, eficientes y seguras para la sociedad y la naturaleza.

Métodos: Se combinan dos instrumentos de planificación mediante el análisis de componentes principales (ACP): el índice de desarrollo territorial sustentable (IDTS), datos 2000-2010 en Colombia y de sus municipios, departamentos y capital, y el de planificación estratégica participativa con escenarios tridimensionales territoriales (PET2) con respecto a la riqueza intelectual territorial.

Resultados: Se establecieron convergencias y divergencias temáticas entre la realidad estadística (IDTS) y las percepciones, intuiciones e intereses de los agentes, donde las relacionadas con la construcción del conocimiento fueron significativas, en especial frente a los tipos de conocimiento académico/científico, empresarial/ingenieril y ciudadano/ancestral/colectivo.

Discusión: En términos epistemológicos y ontológicos, es necesario conocer la convergencia o divergencia entre la realidad y las estadísticas, y en consecuencia, entre la percepción de los gobernantes y los gobernados. A nivel pragmático, se evidencia que las herramientas planteadas son útiles y de fácil manejo, por lo que su uso (conjunto o separado) puede proveer información valiosa y relevante.

Conclusión: Entender el Antropoceno, en su dinámica de sistema socioecológico, y como sistema social de toma de decisiones, garantiza una mejor comprensión de las necesidades y expectativas de la población, para esto es fundamental revisar los criterios y herramientas de evaluación, seguimiento y toma de decisiones.
El orientalismo en la producción cerámica de William de Morgan (1839-1917): las corrientes persa, iznik y andalusí
Authors: Juberías Gracia Guillermo
Published: September 2020

Un periodo clave para el estudio de la historia del diseño contemporáneo fue la segunda mitad del siglo XIX, momento en el que se desarrolló en Gran Bretaña el movimiento de las Arts & Crafts, impulsado por William Morris. Curiosamente, uno de sus colaboradores más cercanos, el ceramista William de Morgan (1839-1917), no ha recibido demasiada atención por parte de los investigadores. A través del presente artículo aportamos nuevas visiones sobre su cerámica inspirada en la tradición islámica, contextualizando la creación de sus piezas en un momento de auge del Orientalismo. Fue, precisamente entonces, cuando numerosas colecciones públicas y privadas británicas se enriquecieron con valiosos ejemplares de cerámica procedente de la antigua Persia, del Imperio Otomano o de España. Las publicaciones existentes sobre William de Morgan no analizan en qué medida estos influjos determinaron su producción, cuestión que abordamos en el presente estudio. Para ello hemos utilizado documentos como su discurso sobre la cerámica de reflejo metálico presentado a la Royal Society of Arts en 1892, así como multitud de sus diseños conservados en los fondos del Victoria and Albert Museum de Londres (V&A). De esta manera hemos podido profundizar sobre el impacto del Orientalismo en la cerámica decimonónica, poniendo en valor la relevancia que los antiguos diseños persas, otomanos y andalusíes tuvieron a la hora de renovar las artes decorativas europeas.
Hablar para decir, no para mentir: la lengua del mito
Authors: López Saco Julio
Published: September 2020

El mito es un discurso narrativo, una «historia» y, en tal sentido, un logos. Se trata de un lenguaje práctico y dialógico, un acto de habla. Un lenguaje que comunica y sirve para pensar. El lenguaje mítico, oral y simbólico, es maleable, hecho que favorece multiplicidad de reinterpretaciones. Este carácter simbólico refiere un pensamiento indirecto de fuerte carga pragmática y pedagógica. Considerado lenguaje original, y catalogado como pensamiento lingüístico metafórico, a la par que lenguaje popular-materno, es un habla elegida por la historia, no definida por su letra sino por la manera en que se dice, por su intención. En este particular, el mito funciona como un metalenguaje con sentido de valor propio. Es también el mito un lenguaje emocional, que evoluciona con la naturaleza y el propio ser humano. En definitiva, es la voz colectiva, en lenguaje figurativo y metafórico, de la comunidad, a la que proporciona cohesión, identidad y un valor socio-político.

La amistad entre Carlo Broschi Farinelli y el marqués de la Ensenada a través de la diplomacia europea, la iconografía, la propaganda, la historia y la literatura
Authors: Martín Sáez Daniel
Published: September 2020

En este artículo presentamos tres manuscritos custodiados en la Biblioteca Nacional de España (BNE), relativos al auge y caída del marqués de la Ensenada, identificados como Mss/5709, Mss/1962 y Mss/11038. Los tres conectan el poder del ministro con el castrato Carlo Broschi Farinelli en la época de Fernando VI, asegurando que ambos colaboraron a través de la ópera y el escuadrón del Tajo para conseguir diversos favores. Algunos historiadores, subrayado la locura de Fernando VI, han asegurado incluso que ambos formaron parte de un «equipo terapéutico» destinado a impedir, a través de los festejos, que los reyes obstaculizaran los proyectos de gobierno. Esto ha dado lugar a una verdadera mitología en torno a la amistad entre Ensenada y Farinelli, pero la realidad es mucho más compleja. Acudiendo a la correspondencia cortesana y otras fuentes –la mayoría de ellas, desconocidas hasta ahora en los estudios farinellianos–, intentaremos aclarar el alcance de esta amistad.
Los gimnasios de Barcelona durante el reinado de Isabel II (1837-1868)
Authors: Torrebadella Flix Xavier
Published: September 2020

Durante el período liberal español en la ciudad de Barcelona se manifestó la emergencia de una nueva culturalidad que nació de las eventualidades de una sociedad compleja y depositaria de signos históricos diferenciales. Esta culturalidad se manifestó en un crecimiento industrial, urbanístico y económico, pero también en las artes, las recreaciones y, además, en la ideológica y la política. En esta coyuntura y prestando atención a las transformaciones sociales, productivas y políticas europeas, en Barcelona se gestó el nacimiento de los primeros gimnasios higiénicos. La localización y el estudio de estos gimnasios es el objeto principal de este artículo, el cual ofrece un campo para poder interpretar mejor el nacimiento de las prácticas fisco-deportivas y sus relaciones sistémicas e ideológicas con otros acontecimientos históricos. La revisión de la prensa histórica depositada en la Biblioteca de Catalunya otorga la posibilidad de indagar en este análisis y coligar un discurso hermenéutico con el soporte de otros estudios de trasfondo y de contexto. Se concluye que la aparición de estos gimnasios no estuvo, en ningún caso, asociada a propósitos nacionalizadores y patrióticos, sino más bien al desarrollo urbano y moderno de un marco social privado y progresista.
Reordenar la ciudad. Policía urbana, orden público y control social en Madrid del Sexenio Democrático
Authors: De Miguel Salanova Santiago
Published: September 2020

Pese a la riqueza que evidencia en sus análisis locales, la producción historiográfica sobre el Sexenio Democrático presenta vacíos significativos en lo que respecta a la evolución de Madrid. El presente artículo buscará cubrir algunos de ellos centrándose en el estudio de las dinámicas que a lo largo de ese período advirtieron los poderes locales de la ciudad, sometidos a una experiencia democratizadora. A partir de la consulta de la documentación de policía urbana del Ayuntamiento de Madrid, se abordarán las políticas de intervención de un gobierno municipal renovado en sus idearios con relación al cambio de escala que había reflejado la urbe en las últimas décadas del período monárquico. De manera específica, se estudiarán las iniciativas concernientes a la implementación de unos mecanismos de «buen gobierno» en la ciudad, los cuales, en realidad, encubrían la pretensión de reconfigurar el espacio urbano para hacerlo legible y transparente en cuanto concernía a sus usos y prácticas sociales cotidianas.
