Characterization of Varroa destructor Mites in Cuba Using Mitochondrial and Nuclear Markers
Authors: Rodríguez Anais , Yadró Carlos A. , Pérez Adolfo , Invernizzi Ciro , Tomasco Ivanna 
Published: November 2020

Abstract

Varroa destructor has been present in Cuba since 1996, but without the use of acaricidal infestation rates remain at very low levels. The presence of Korean haplotype mites was described in 2007, but there is no information regarding the introgression of the less virulent Japanese haplotype that could account for a low pathogenicity of the mite. In this research, we carried out molecular characterization of Cuban Varroa mites through mitochondrial DNA and hypervariable nuclear loci. We applied an alternative RFLP technique and found that all the analyzed samples corresponded to Korean haplotypes. We analyzed the three STRs loci VD112, VD114 and VD016, previously described as highly variable and found new alleles in all of them, with an absolute allele size very different to those reported worldwide. We also detected genic and genotypic differentiation between samples from two nearby locations (P=0.08). We also tested a new RFLP method for mite haplotype discrimination with an intra-reaction positive control of digestion.

Published: November 2020

Abstract
Honey from the western region of Paraná receives the seal of origin and in-process denomination of origin because it is mostly produced in permanent preservation areas, adherence to hygiene and sanitary standards, proper management techniques and agro-industrial management. The objective of this study was to verify the microbiological quality of honey produced by beekeepers associated with Cooperative. Sixty-seven honey samples were evaluated for microbiological quality, and the mean values observed to total aerobic mesophiles were 2.52 log CFU/g; Clostridium spp. 1.46 log CFU/g; total coliforms 0.78 log CFU/g; fecal coliforms 0.50 log CFU/g; total yeasts 0.46 log CFU/g, and 2.95 log CFU/g total molds. The evaluations showed the incidence of anaerobic mesophilic in 70% of the samples, Clostridium spp. 77%; total coliforms 60%, fecal coliforms 62%, molds 83% and 34% yeasts. Five genera of the isolated molds commonly found in honey were Fusarium spp. 0.35 log CFU/g; Aspergillus spp. 0.52 log CFU/g; Cladosporium spp. 1.2 log CFU/g, Phoma spp. 0.71 log CFU/g and 0.16 log CFU/g Penicillium spp. Multivariate analysis showed the formation of two groups and indicated the heterogeneity in the bacterial load of the samples. Although microbiological analyses were not mandatory for honey, these results demonstrated the hygienic-sanitary quality of the samples of honey produced. For the reduction of secondary-origin microorganisms, the handlers were recommended to follow the sanitary hygiene norms and handling techniques.
Did the Bubble Burst? The Portuguese Economy During COVID-19
Authors: Tomé Eduardo , Gromova Elizaveta , Hatch Andrew 
Published: November 2020

Abstract
In this paper we analyse the situation of the Portuguese Economy referring to the Covid-19. We start by contextualizing in the problematic “Bubble – Miracle” as described by Tomé, 2018. We then analyse the current situation in a Macroeconomic way, according to eight specific questions, and then we specify regarding four sectors, namely tourism, education, the public sector, and the industrial sector. We conclude that the Covid-19 is the ultimate and unexpected test to the Portuguese economy, and that it will contribute to solving the “Bubble vs. Miracle” question. Rather curiously, we believe that the Covid-19 will accelerate the change to the “Miracle” society, because solving the crisis will require changes that will direct the society towards the “Miracle” paradigm and will distance Portugal from the old and “Bubble” one.
Reaching for the Stars: The Role and Value of Digital Reputation
Authors: Gandini Alessandro 
Published: November 2020

Abstract
In the old economy, reputation was considered an important but somewhat underestimated intangible asset. In the digital economy, the significance of reputation is expanded in scope. It enables the building of trust among “quasi-strangers” who engage in an economic transaction. Reputation scores, usually in the form of feedback, ranking and rating systems, facilitate the building of trust in the absence of a direct relationship between sellers and buyers. Concomitantly with the rise of social network sites and the proliferation of metrics and analytics of all kinds, the era of the “reputation economy” has dawned. A good reputation usually brings further good evaluations. On the other hand, a bad reputation can be a long-term setback for a company. Having no reputation means virtual non-existence in the eyes of today’s consumers. Professional reputation management is therefore a core task that makes a decisive contribution to the success of a company.
Navigating by the Stars: Current Challenges for Ensuring Trust in the Sharing Economy
Authors: Möhlmann Mareike , Teubner Timm 
Published: November 2020

Abstract
Today, virtually all e-commerce and sharing-economy platforms rely on star ratings or similar systems to build trust between anonymous buyers and sellers. However, star ratings can be quite tricky as a navigation aid. Platforms and users face several challenges in making sure that reputation systems remain credible. Skewed ratings and low rating variance, however, make it difficult for users to differentiate good from bad products and services. To tackle the issue of retaliation, most platforms use so-called simultaneous review schemes, only publishing ratings once both parties have committed. Furthermore, platforms may offer individuals the opportunity to leave text reviews as a complement to numeric ratings. A growing number of platforms also use complex technical systems and algorithms to automatically identify, mark or delete fake news. To maintain legitimacy, platform operators need to design reputation systems with minimal negative side effects and make crucial decisions about the level of control they seek to enact.
Detecting and Mitigating Discrimination in Online Platforms: Lessons from Airbnb, Uber, and Others
Authors: Luca Michael , Svirsky Dan 
Published: November 2020

Abstract
Research has documented racial or ethnic discrimination in online marketplaces, from labor markets to credit applications to housing. Platforms should therefore investigate how platform design decisions and algorithms can influence the extent of discrimination in a marketplace. By increasing awareness of this issue, managers can proactively address the problem. In many cases, a simple but effective change a platform can make is to withhold potentially sensitive user information, such as race and gender, until after a transaction has been agreed to. Further, platforms can use principles from choice architecture to reduce discrimination. For example, people have a tendency to use whatever option is set as the default. If Airbnb switched, for instance, ist default to instant book, requiring hosts to actively opt out of it, the company could reduce the scope for discrimination. It is important that discrimination and possible solutions are discussed transparently.
Tales from the Land of Consumer Reviews: Taking a Closer Look at Lurkers and Writers
Authors: Mafael Alexander , Gottschalk Sabrina 
Published: November 2020

Abstract
While most consumers routinely read online reviews to inform their purchase decisions, the number of consumers who actively post reviews is astonishingly small. To find their way in the review jungle, readers process the information presented very selectively and pursue different objectives. They use different informational cues for their own decision-making, which often reflects rather stable patterns. Writers, too, are often less interested in presenting their experience as objectively as possible as contextual factors play an important role. Similar to the review readers, they act neither uniformly nor without biases. Whether they take up the pen at all depends, among other things, on whether they represent a majority or minority opinion and what image of themselves they want to convey. A profound understanding of the motives of readers and writers is important to improve one’s own rating system and requires special skills in the management of online ratings. Managers need to find ways to convert more lurkers into posters to get a more realistic picture of the experiences.
It’s the Story, Stupid: The Consumer Reviews Most Likely to Influence Purchasing Decisions
Authors: van Laer Tom 
Published: November 2020

Abstract
Helpful reviews are like good movies or a good novel: if you’re hooked right away, you stay and remember. No matter how short, a review tells a story in much the same way as a novel. If you want to persuade, it should start with something dramatic and sensational or the key takeaway, rather than saving the best elements for the end. Narrative elements can change the way reviews influence people, and media literacy can go a long way. Social media influencers and professional reviewers should now also know that they are better off investing in creative writing or storytelling courses than choosing to analyze experiences factually. Further, software developers should learn to distinguish useful reviews from less helpful or relevant ones. With such skills, they can structure platforms in ways that make writing transporting, helpful, persuasive reviews as easy as possible and can develop algorithms that favor real and useful reviews.
Primary hypoparathyroidism in a patient with common variable immunodeficiency associated enteropathy
Authors: Ismayilov Rashad , Simsir Ilgin Yildirim , Akyol Deniz , Ardeniz Fatma Omur 
Published: November 2020

Abstract

Background. Common variable immunodeficiency (CVID) is a rare disease characterized by humoral immunodeficiency, often causing sinopulmonary and gastrointestinal infections, and may cause enteropathy in some patients, which leads to severe malnutrition and electrolyte deficiencies. Although many autoimmune diseases are seen with increased frequency in CVID patients, primary hypoparathyroidism is extremely rare.

Case presentation. A 50-year-old man with CVID presented with diarrhea. The patient had complaints for 2 years and was cachectic. He had severe electrolyte and vitamin deficiencies that did not respond to oral treatment. The diarrhea causes such as celiac, inflammatory bowel diseases, and gastrointestinal infections were excluded and the endoscopy showed enteropathic changes in the duodenum and colon. Concomitant hypoparathyroidism was also detected in the patient with hypocalcemia despite adequate replacement.

Conclusion. Parenteral therapy should be considered in the management of CVID enteropathy cases that do not respond to oral replacement. Although very rare, hypoparathyroidism should be considered in the differential diagnosis of CVID patients with treatment-resistant hypocalcemia.
Three-tier stratification for CNS COVID-19 to help decide which patients should undergo lumbar puncture with CSF analysis: a case report and literature review

Published: November 2020

Abstract
The COVID-19 pandemic continues to overwhelm global healthcare systems. While the disease primarily causes pulmonary complications, reports of central nervous system (CNS) involvement have recently emerged ranging from encephalopathy to stroke. This raises a practical dilemma for clinicians as to when to pursue neuroimaging and lumbar tap with cerebrospinal fluid (CSF) analysis in COVID-19 patients with neurological symptoms. We present a case of an encephalopathic patient infected with SARS-CoV-2 with no pulmonary symptoms. We propose a three-tier risk stratification for CNS COVID-19 aiming to help clinicians to decide which patients should undergo CSF analysis. The neurological examination remains an integral component of screening and evaluating patients for COVID-19 considering the range of emerging CNS complications.

Published: November 2020

Abstract
Aim: The main aim is to show that the life of a patient depends on the decisions the doctor makes as well as the proper assessment of the case. The decision to avoid a surgical procedure and continuewith the conservative treatment following the vital parameters, was beneficial for the patient who was later discharged recovered.
Case report:The case is about a patient who was in labor for the fifth time with the delivery complicated by severe postpartum hemorrhage in the secondary health care institution. Despite all conservative measures taken, the hemorrhage hasn’t stopped, therefore, the subtotal hysterectomy was performed, after which the patient was directed to the Clinical Centre Kragujevac. Regarding the fact that the postpartum hemorrhage hasn’t stopped and abdominal hematoma as well as intracranial hemorrhagewere diagnosed, the main dilemma was if the surgical procedure should be redone or if the conservative treatment should be continued. By applying the conservative treatment andcontinued consultations of the multidisciplinary team, the patient was discharged from the Clinical Centre Kragujevac. Conclusion: The main issue with severe cases like this one, is to define and direct the treatment towards the lower risk rate – repeated surgery could be fatal with the current state of the patient. The estimation was correct, at the end, the patient was released after thelengthy treatment, recovered.

Afectividad, política y conocimiento: resistencia al neoliberalismo desde la escena teatral latinoamericana
Authors: Proaño Gómez Lola 
Published: November 2020

Este ensayo se pregunta por la forma en que se relacionan el poder y la vida en la escena teatral latinoamericana, y el peso de la afectividad en esa relación, ejemplificando las hipótesis propuestas en el análisis de Millones de segundos (Argentina 2017) y Simplemente José (Colombia 2012). El teatro es un territorio privilegiado para la expresión de la afectividad y es posible obtener conocimiento político a través de las sensaciones que los cuerpos transmiten. Siguiendo y discutiendo las propuestas del giro afectivo y con el concepto de atmósfera afectiva en mente, se propone leer las emociones que se despliegan en la escena como una forma de resistencia, desde la biopotencia al biopoder implementado por el neoliberalismo. Affectivity, Politics and Knowledge: Resisting Neoliberalism in Latin American TheatreAbstractThis article tries to answer the question of the articulation between power and life in the Latin American theatre scene. It reflects on the weight that affectivity has in that relationship in the field of politics, exemplified by the Latin American scene (Millions of Seconds, Argentina, 2018 and Simply José, Colombia, 2012). The theater is a privileged territory for the expression of affectivity, and it is possible to obtain political knowledge through the sensations/emotions that the characters and their bodies transmit in the scene. Discussing the affective turn theory with the help of the affective atmosphere concept, we propose to read the emotions that unfold on the scene as a form of resistance to the biopower implemented by neoliberalism.

La comunicación entre actor y espectador: una aproximación al psicoanálisis
Authors: Zúñiga Vargas Iván 
Published: November 2020

Este artículo se plantea una búsqueda de los vínculos que surgen entre actor, espectador y público en base a los escritos de Luisa Josefina Hernández en torno a un teatro trágico desde la perspectiva aristotélica, un teatro que nos lleva a desentrañar lo más sublime y lo más oscuro de nosotros mismos. A partir de la confrontación de la fórmula básica del código teatral de Erika Fischer-Lichte y las teorías de Lacan sobre el inconsciente, se propone un modelo de la comunicación en el teatro con el fin de evidenciar la complejidad psíquica del fenómeno escénico. The Communication Between Actor and Spectator: a Psychoanalytical AbstractThis article addresses how theatrical communication takes place between performers and spectators, seeking the links that are established between them. The author picks up Luisa Josefina Hernández’s vision of a tragic theater from the Aristotelian perspective, a theatre that leads us to unravel the most sublime and the darkest in ourselves. Starting from the confrontation of the basic formula of Erika Fischer-Lichte’s theatrical code and Jacques Lacan’s theories about the unconscious, the author proposes a model of communication in theater that demonstrates the psychic complexity of the phenomenon.

Ensayos de poder colegiado: las asambleas provinciales en la organización republicana
Authors: Cartes Montory Armando 
Published: November 2020

Con la Independencia, la reconfiguración del poder estatal planteó la cuestión de la representación territorial y la administración de los espacios subnacionales. El recurso inicial a las juntas y cabildos, como instancias de participación política, mostró pronto su insuficiencia frente a las nuevas realidades. Las asambleas provinciales reflejaron el protagonismo de las provincias en esta fase de la organización de la república. Si bien existen antecedentes coloniales y de la transición republicana, los cuerpos colegiados regionales surgen con fuerza durante la llamada “anarquía” (1823-1830). Desaparecidos formalmente en la Carta de 1833, reaparecen en el siglo XX, como expresión de una aspiración regional. En el actual régimen de gobierno y administración interior, han adoptado la forma de Consejos Regionales. Su creciente empoderamiento da cuenta de una forma nueva de territorializar el poder; la que dialoga, no obstante, con los proyectos frustrados del albor republicano.
LA DUALIDAD ADMINISTRATIVA DE TACNA Y ARICA DURANTE LOS PRIMEROS AÑOS DE “CHILENIZACIÓN”. 1890-1910
Authors: Miranda Wilson Giannina 
Published: November 2020

El Tratado de Ancón confirió a Chile la posesión de Tacna y Arica por diez años, tras los cuales un plebiscito debía determinar si pasaban a su dominio y soberanía o retornaban al Perú. No obstante, el Estado peruano llevó a cabo estrategias para contrarrestar las políticas de “chilenización” y conservar la adhesión de sus “provincias cautivas”. Para ello subvencionó agentes que incursionaron precisamente en espacios que suelen moldear el carácter nacional de los individuos: escuelas, parroquias, sociedades benéficas y prensa. Este artículo pone en evidencia algunos testimonios de esa suerte de doble administración que tuvieron ambas provincias: una formal chilena con base jurídica, y otra informal y clandestina, llevada a cabo por el Perú. Estas acciones peruanas clandestinas contribuyeron a que durante las primeras décadas del siglo XX Chile aplicara políticas drásticas contra los agentes peruanos y la población irredenta.
BIENES COMUNES, MODERNIZACIÓN URBANO-PORTUARIA Y CONFLICTO SOCIO-AMBIENTAL. EL CASO DE LOS PESCADORES DE CALETA JAIME EN VALPARAÍSO A PRINCIPIOS DEL SIGLO XX
Authors: Camus Pablo , Álvarez Luis , Castillo Sebastián , Hidalgo Rodrigo 
Published: November 2020

Este estudio se centra en la discusión sobre Caleta Jaime durante 1915 y 1916, en el contexto de las obras de la Estación Barón en Valparaíso. Sus objetivos son estudiar a los actores que estuvieron públicamente a favor de los pescadores y sus declaraciones; explicar la actuación de las autoridades reacias a mantener la caleta en su sitio original; comprender la erradicación de los pescadores artesanales porteños como parte de la modernización y del control de as costas chilenas de aquella época. La fuente primaria que sustenta este estudio es el periódico El Mercurio de Valparaíso, medio que realizó una campaña explícita a favor de los intereses de los pescadores de Caleta Jaime. Pese a la intensa campaña desplegada por El Mercurio y a la defensa pública de algunas utoridades, la modernización y apropiación fiscal de un espacio litoral tan central era inevitable.
ABSTRACT
This study focuses on the discussion about the future of Caleta Jaime between 1915 and 1916, when there were built Valparaíso Puerto Barón train station. The main objectives are to show the actors that supported fishermen’s demands and analyze their speeches, explain the performance of reluctant authorities to keep the cove on its original site, base why fishermen suffered unavoidable enclosure and show social control like an inherent aspect to chilean coast in mid 1910s. Our primary source is the journal El Mercurio de Valparaíso, which made an explicit campaign in favor of Jaime fishermen’s interest. The main idea is that some projects were approved to enclose and extinguish Caleta Jaime, despite releases of El Mercurio and public defense made by some state authorities and parliamentarians.
