La película colombiana el Abrazo de la Serpiente, dirigidapor Ciro Guerra y producida por Cristina Gallego,se consolidó en el 2016, como el sucedo cinematográficodel año. La nominación a los Premios Óscar dio al film ungiro inesperado, que desde la fecha de su estreno en mayode 2015, había tenido el aplauso de la crítica internacionaly reconocimiento en prestigiosos Festivales de Cine,pero había pasado desapercibida en las salas de cine enColombia. En esta entrevista, Cristina Gallego habla sobrelos aprendizajes de la película, el culto al mito Hollywoody los retos de los cineastas para contar nuevas historias enun contexto, donde la construcción de paz, ha pasado deser un asunto exclusivo del Estado y los actores armadosilegales, para convertirse en un tarea que depende de la diversidady el respeto a la diferencia, entre diversos sectoresde la sociedad civil.
Cuerpos significantes. Nuevas travesías dialécticas
Authors: Citro Silvia
Published: August 2020

Este artículo traza una breve genealogía de mis investigaciones socioantropológicas sobre la corporalidad en Argentina, partiendo del entrecruzamiento entre ciertas experiencias intersubjetivas que involucraron intensamente la corporalidad desde lo sensorial y emotivo, las performances artísticas y las etnografías realizadas desde mediados de los años noventa. A partir de esta travesía inicial, que vincula experiencias personales y producciónartística e intelectual, en un contexto geopolítico e histórico determinado, discuto tres problemáticas teóricometodológicas claves en el campo actual de los estudios sobre el cuerpo en América Latina, por cuanto constatamos que también otros colegas de nuestros países las comparten. En primer lugar, sobre los modos en que nuestras corporalidades y, agregaría, nuestras producciones intelectuales sobre el cuerpo son el resultado de un complejo entramado de materialidades biológicas, tecnologías, procesos psicológicos,intersubjetivos, históricos y político-culturales que entrelazan sensaciones, movimientos,afectividades, imágenes, representaciones y discursos. Por ello, creemos que el desafío ante tal complejidad es evitar caer en un reduccionismo del cuerpo que lo someta a la mirada unilateral de una sola disciplina, y tratar de avanzar, en cambio, hacia una progresiva interdisciplinariedad.
Construcción de cuerpos: Fortaleza y armonía en los ideales de cuerpo-sonidomovimiento en las poblaciones afrochocoanas
Authors: María Arango Ana
Published: August 2020

Esta ponencia es una reflexión sobre uno de los principales conceptos de lainvestigación Velo qué bonito: saberes y prácticas sonoro-corporales en la primera infancia de las poblaciones afrochocoanas: la “fortaleza armónica”.Tras tres años de investigación en cinco municipios del Chocó, uno de sus principales hallazgos fue comprender que los cuidados, imaginarios y discursos alrededor de la relación entre cuerpo, sonido y movimiento reposan en labúsqueda de una fortaleza que, más que física, es espiritual, y de una armonía que se sustenta en la compenetración con el entorno, los seres supranaturales y los lazos familiares.La fortaleza armónica, como ideal que buscan las madres y abuelas choconas en sus bebés, y que más adelante refuerzan los demás miembros de la comunidaden diferentes prácticas sonoro-corporales, muchas veces choca con las políticas y discursos hegemónicos del Estado y que propenden por la consolidación de tipos concretos de subjetividad insertos en la modernidad y la idea de nación.
El aula agonal: una mirada a las relaciones discursivas entre profesor y estudiantes desde una ética agonística
Authors: Roa Sánchez Óscar Felipe
Published: August 2020

El siguiente trabajo se propone aportar elementos conceptuales en torno a la reflexión de las interacciones discursivas que se tejen entre profesor y estudiantes dentro del aula escolar. Elementos que nos acercan a la problemática de reconocer una dimensión ontológica de oposición o negatividad en las relaciones sociales en general, y en los procesos de enseñanza/aprendizaje en particular. Si bien desde los estudios contemporáneos del discurso y de la filosofía política se ha considerado lo agonístico por su potencia evaluadora, por cuanto lo agonal configura las relaciones de los participantes no como enemigos sino como adversarios, no se le ha dado suficiente reconocimiento para un análisis de las prácticas discursivas y la manera como se desenvuelven en el aula. En este estudio se tiene, en primer lugar, el modelo de análisis conversacional en el aula propuesto por Sinclair y Coulthard (1975) y se consideran algunos aportes del enfoque sociocomunicativo de Charaudeau (2012), para describir su entramado situacional. En segundo lugar, se trabaja el discurso pedagógico como dispositivo que transmite, no solo contenidos particulares según la disciplina, sino también como uno a partir del cual se establecen órdenes, relaciones e identidades sociales (Bernstein, 1994). Por último, la caracterización de una ética agonística como orientación filosófica y política para encarar de manera activa las prácticas de la vida escolar (Mouffe, 2006). De esta manera, los resultados se relacionan con el desarrollo discursivo de la oralidad en participantes que se enfrentan a la solución de conflictos dentro de un aula agonal.

Published: August 2020

El desarrollo de la comunicación científica es un elemento básico para todos los estudiantes universitarios en la actualidad, pues la dinámica de la sociedad requiere comunicar con coherencia y cohesión los resultados de la investigación. El objetivo del artículo es socializar la experiencia de cómo potenciar la comunicación científica oral en los estudiantes de Medicina Veterinaria y Zootecnia de la Universidad Central “Marta Abreu” de Las Villas. Para el desarrollo del trabajo se utilizaron métodos del nivel empírico como la observación y la revisión bibliográfica. Se realizó una prueba pedagógica de entrada a los estudiantes de primer y cuarto años que cursaban la carrera de Medicina Veterinaria y Zootecnia en dicha universidad, en el curso académico 2013-2014; esta evidenció carencias en la comunicación científica oral de los estudiantes. Para erradicar los problemas detectados se elaboraron e implementaron acciones didácticas que perfeccionaran este tipo de comunicación en los estudiantes muestreados. Actualmente los estudiantes valoran de manera positiva la importancia social y cultural que tiene en la actividad científico-investigativa la comunicación científica oral.
Iniciativa ciudadana “#Noen3caínes”. Análisis del discurso de un acontecimiento
Authors: Ospina Raigosa Luis Eduardo
Published: August 2020

En este artículo se realiza un estudio crítico del discurso (ECD) de un fragmento del video Narconovelas-Movimiento ciudadano #Noen3caínes (García y Cartagena, 2013) que da cuenta de la iniciativa ciudadana #Noen3caínes. En esta, los ciudadanos interpelan al medio de comunicación, lo que la constituye en una respuesta social. Como objetivo general se va a interpretar la respuesta social denominada Noen3caínes, a partir de los significados que se proponen en el video de análisis. Noen3Caínes tuvo efectos concretos en la pauta de la teleserie Tres Caínes del Canal RCN en Colombia. Al menos 13 marcas retiraron su publicidad gracias a la presión ciudadana desde internet, porque consideraron que su imagen no era afín con esa propuesta televisiva, asunto que no tiene precedente en la historia de los medios en Colombia.
La lectura: puerta de entrada a los bosques narrativos
Authors: Fajardo Valenzuela Diógenes
Published: August 2020

Los grandes escritores siempre han reconocido la importancia de la lectura como punto de partida de sus exitosascarreras literarias. El objetivo de este artículo es, por un lado, justificar el acercamiento de los niños a laliteratura como parte fundamental de una educación para la aceptación del otro con tolerancia y respeto a suscreencias y narrativas; y por otro, analizar el proceso de lectura, entendida como puerta de entrada a los bosquesnarrativos en donde debemos participar activamente. La lectura de solo imágenes se inicia desde el vientrematerno. Luego se combina con la palabra, de suerte que tenemos libros ilustrados y los llamados libros-álbum,para finalmente llegar al libro conformado tan solo por el texto escrito. La invitación, realizada con la ayuda deUmberto Eco, es la de llevar al niño a bosques narrativos donde pueda jugar a ser copartícipe en la creación dela historia como también a perderse en ella.
Течение Куэтта горячего вязкого газа
Authors: Хорин Александр Николаевич , Khorin Aleksandr Nickolaevich , Конюхова Анастасия Анатольевна , Konyukhova Anastasia Anatolevna
Published: August 2020

Найдено новое точное решение уравнений движения вязкого газа для плоского стационарного сдвигового течения горячего (800-1500 K) газа между движущимися с разными скоростями параллельными пластинами (аналог несжимаемого течения Куэтта). Одна из пластин считалась теплоизолированной. Для зависимости коэффициента вязкости от температуры принята формула Сазерленда. В отличие от других известных точных решений, вместо аналогии Рейнольдса (предположение о линейной связи между коэффициентами вязкости и теплопроводности) для вычисления коэффициента теплопроводности использована более точная формула, имеющая в рассматриваемом диапазоне температур ту же точность, что и формула Сазерленда (2 %).
С использованием полученного точного решения исследовано качественное влияние сжимаемости на напряжение трения
и на профили температуры и скорости. Показано, что (если одна из пластин теплоизолирована) сжимаемость газа приводит к увеличению напряжения трения. Проведено сравнение нового точного решения с известным точным решением (V. N. Golubkin, G. B. Sizykh, 2018), полученным с использованием формулы Сазерленда для коэффициента вязкости и аналогии Рейнольдса для коэффициента теплопроводности. Обнаружено, что оба решения приводят к одинаковым выводам о качественном влиянии сжимаемости на напряжение трения и на профили температуры и скорости. Однако прирост напряжения трения, вызванный сжимаемостью, при использовании аналогии Рейнольдса оказался недооцененным в два раза. Это показывает, что предположение о линейной связи между коэффициентами вязкости и теплопроводности может приводить к заметным количественным ошибкам.

Do blogs as a virtual space foster students’ learner autonomy? A case study
Authors: Hannam Georgie
Published: August 2020

UK higher education institutions strive to foster learner autonomy in their students to create more successful learners, yet due to its complex nature, educators and academics continue to search for effective ways to achieve this. This case study investigates how one virtual blogging space on the Independent Learning (IL) pre-sessional module at the University of Southampton seeks to cultivate learner autonomy. This qualitative study was driven by a lack of empirical research exploring both perceptions and practices in social learning spaces. Investigations into both of these elements help to gain a deeper understanding of how learning spaces function, which is essential to recognising how they can meet their pedagogical goals. Whilst the blogging space was effective in fostering learner autonomy to some extent, there was evidence of conflicts in how the students, IL Facilitators (ILFs), and curriculum designers perceived the blogging space. This suggests the need for more time spent conveying the rationale of the blogging space to ILFs and subsequently students, and it also highlights the wider importance of understanding individual context.
Task-based language learning through digital storytelling in a blended learning environment
Authors: Meri-Yilan Serpil
Published: August 2020

This study investigated Task-Based Language Learning (TBLL) through Digital StoryTelling (DST) in a blended learning environment. Twenty-six Turkish university-level students prepared a DST individually and shared it with their peers in an online discussion platform. Each evaluated and graded others’ DST performance based on an assessment scale. After this, they performed their stories in the classroom and similarly assessed their peer’s performances. Ultimately, they were asked to give their self-reflection on the pros and cons of performing tasks online and in the classroom. Findings showed that TBLL through DST was more favoured than storytelling in the classroom and helped them to improve their speaking skills. The study suggested DST could be a positive approach in language learning and should be explored further in other language skills and multiple contexts.
Loneliness as a potential consequence of the presence of children in the digital world.
Authors: Agnieszka Iwanicka Agnieszka Iwanicka
Published: August 2020

The feeling of loneliness is a condition that affects not only adults and youth, but also children. It may be a temporary and transient in nature, occurring as a response to external circumstances, although it can also be long-lasting, as long as months and years, and be a result of deep, traumatic childhood experiences. One of its most common sources is isolation of a child in a family, peer groups and at school. In the article, the author considersnwhether the sense of loneliness experienced by children can also be traced back to the media and the functioning of children in the digital environment. Thanks to the conductednqualitative study (focus interviews with children), the paper answers questions regarding how early school-age children perceive loneliness and isolation, and whether they link this phenomenon with digital media.
When Law Forgets About Dignity”: Selected Historical and Modern Contexts of Sterilisation of People with Disabilities
Authors: Sobański Piotr
Published: August 2020

What is human dignity? How to define the dignity of a person? Is it possible to identify key features that show the principles of respecting the dignity of another person? Attempts to define the concept indicated here may inevitably fail. On the one hand, human dignity is a universal concept. It refers to all people. Nevertheless, on the other hand, each of us has our own sense of dignity. Paradoxically, e.g., humiliation of a particular person’s dignity shows us the importance of the area that has been violated. Similar violations often affect sick and disabled persons. Examples of similar activities throughout human history abound. In this context, special attention should be paid to the interventions undertaken by the Nazis before theoutbreak of WWII. Here, we are talking especially about mass and legalised activities that resulted in the sterilisation of many thousands of people with intellectual disabilities, people with physical disabilities and people experiencing mental disorders. The Nazi practices indicated here are presented as examples of human right violations. At the same time, they are examples of the unlawful rule of the state over an individual. Is there still a danger of reverting to similar practices today? Can standards of respect for human rights created years ago successfully protect disabled people against violation of their dignity? Can the knowledge of Nazi activities still be important to us? The presented article is intended as an attempt at answering these questions.
Types of grammatical and lexical errors made by students with a mild intellectual disability at the second stage of their education a qualitative analysis
Authors: Marciniak-Firadza Renata
Published: August 2020

The aim of the article is to provide a qualitative description of the errors committed by pupils with mild intellectual disabilities. The discussed issue has not yet been the subject of a scientific description from a linguistic point of view. The analysis of errors was based on Andrzej Markowski's classification with small additions from Zygmunt Saloni’s classification. Due to the volumetric framework, the article is limited to discussing grammatical and lexical errors. The research showed that pupils with mild intellectual disabilities make similar errors as those with typical development. No qualitative differences were noted between the study group and the control group, only quantitative ones.
A prehistoric copper-production centre in central Thailand: its dating and wider implications

The Khao Wong Prachan Valley of central Thailand is one of four known prehistoric loci of copper mining, smelting and casting in Southeast Asia. Many radiocarbon determinations from bronze-consumption sites in north-east Thailand date the earliest copper-base metallurgy there in the late second millennium BC. By applying kernel density estimation analysis to approximately 100 new AMS radiocarbon dates, the authors conclude that the valley's first Neolithic millet farmers had settled there byc. 2000 BC, and initial copper mining and rudimentary smelting began in the late second millennium BC. This overlaps with the established dates for Southeast Asian metal-consumption sites, and provides an important new insight into the development of metallurgy in central Thailand and beyond.
Rethinking pig domestication in China: regional trajectories in central China and the Lower Yangtze Valley
Authors: Dong Ningning , Yuan Jing
Published: August 2020

Animal domestication represents one of the most important advances in human history. Pigs (Sus scrofa) were domesticated multiple times in prehistory and are therefore ideal for examining how geography and culture shape the domestication process. The authors integrate zooarchaeological and isotopic data from Neolithic (c. 10 000–2000 BP) pigs from central China and the Lower Yangtze Valley to demonstrate two dominant domestication trajectories. In central China, pig husbandry intensified following domestication, corresponding with population growth and a shift in socio-economic organisation. In the Lower Yangtze Valley, however, increasing urbanism was associated with a preference for wild resources supplemented by the limited exploitation of domestic pigs.
Client Outcomes From a Multilevel Intervention to Support Persons Living With HIV and Returning to the Community After Incarceration in Puerto Rico

Published: August 2020

The twin epidemics of HIV and incarceration impact Puerto Rico, which has limited resources to address the social and structural determinants of health in incarcerated populations. A Special Programs of National Significance grant supported a Puerto Rican community-based organization to implement the evidence-informed Transitional Care Coordination intervention among incarcerated persons living with HIV, targeting changes at the individual, organization, and systems levels. After implementation (November 2015–July 2018; n = 69), 93.1% of eligible clients were linked to community-based HIV care, 86.3% remained in care for 6 months, and 78.6% remained for 12 months. A greater proportion reported consistent HIV care, ART adherence, food security, and transportation to access care. Integrating HIV case management with housing and employment services, and developing buy-in and collaboration from partners across systems of care, including after a natural disaster, led to positive client outcomes. This intervention shows promise for adaptation to other HIV care and service delivery systems.

Ragtime Country
Authors: Marshall Wayne
Published: August 2020

In 1955, Elvis Presley and Ray Charles each stormed the pop charts with songs employing the same propulsive rhythm. Both would soon be hailed as rock 'n' roll stars, but today the two songs would likely be described as quintessential examples, respectively, of rockabilly and soul. While seeming by the mid-50s to issue from different cultural universes mapping neatly onto Jim Crow apartheid, their parallel polyrhythms point to a revealing common root: ragtime. Coming to prominence via Maple Leaf Rag (1899) and other ragtime best-sellers, the rhythm in question is exceedingly rare in the Caribbean compared to variations on its triple-duple cousins, such as the Cuban clave. Instead, it offers a distinctive, U.S.-based instantiation of Afrodiasporic aesthetics—one which, for all its remarkable presence across myriad music scenes and eras, has received little attention as an African-American “rhythmic key” that has proven utterly key to the history of American popular music, not least for the sound and story of country. Tracing this particular rhythm reveals how musical figures once clearly heard and marketed as African-American inventions have been absorbed by, foregrounded in, and whitened by country music while they persist in myriad forms of black music in the century since ragtime reigned.

Minuman probiotik adalah salah satu jenis minuman yang difermentasi dalam jangka waktu tertentu. Tujuan dari penelitian ini adalah untuk mengetahui perbedaan waktu fermentasi terhadap kadar probiotik sari buah stroberi (Fragaria anannassa). Penelitian dengan desain rancangan acak kelompok (RAK) menggunakan satu faktor yaitu perbedaan waktu fermentasi (20 jam, 24 jam, 28 jam). Masing-masing perlakuan dilakukan 2 kali ulangan sampel. Analisis yang dilakukan meliputi analisis kadar probiotik dan aktivitas antioksidan. Hasil penelitian menunjukkan bahwa sampel yang difermentasi selama 20 jam menghasilkan jumlah koloni bakteri sebanyak 1,8×1015 cfu/ml dan aktivitas antioksidan sebesar 1112 ppm. Sampel yang difermentasi selama 24 jam menghasilkan jumlah koloni bakteri sebanyak 3×1015 cfu/ml dan nilai aktivitas antioksidan sebesar 985 ppm, sampel yang difermentasi selama 28 jam menghasilkan jumlah koloni bakteri sebanyak 5,5×1015 cfu/ml dan nilai aktivitas antioksidan sebesar 865 ppm. Tidak ada perbedaan pada hasil analisis meskipun rerata kadar probiotik dan aktivitas antioksidan menunjukkan adanya peningkatan disetiap jamnya. Semakin lama waktu fermentasi maka kadar probiotik dan aktivitas antioksidan semakin meningkat.
Benefits of 11C-methionine PET/MRI and intraoperative fluorescence in treating hyperparathyroidism
Authors: Luong Thien Vinh , Rejnmark Lars , Arveschoug Anne Kirstine , Iversen Peter , Rolighed Lars
Published: August 2020

Multiple endocrine neoplasia 1 (MEN1) is a rare genetic syndrome characterized by the manifestation of tumors in endocrine glands most often in the parathyroid gland (PG). Treatment may involve several parathyroidectomies (PTX), especially in young patients, which increases the risk of postoperative complications. We present a 16-year-old patient with a family history of MEN1 syndrome. The patient started to show biochemical signs of hyperparathyroidism (HPT) and hypercalcemia at the age of 10. One and a half years later a PTX was successfully performed with removal of the two left PGs. However, a rise in plasma parathyroid hormone and ionized calcium was observed 4 years later. Preoperative noninvasive imaging with 99mTc-sestamibi scintigraphy showed no definitive parathyroid adenoma. A 11C-methionine position emission tomography combined with MRI (MET-PET/MRI) was then performed and detected a focus posterior to the lower part of the right thyroid lobe. Intraoperative angiography with fluorescence and indocyanine green dye was used to assess the vascularization of the remaining PGs. The lower right PG was removed. The patient was discharged with normalized biochemical values and without postoperative complications. Recurrence of primary HPT is frequent in MEN1 patients which often necessitates repeated operations. Our case report showed that the use of advanced noninvasive preoperative imaging techniques and intraoperative fluorescent imaging are valuable tools and should be taken into consideration in selected cases to avoid postoperative complications. To our knowledge, this is the first case where MET-PET/MRI has been used to detect parathyroid pathology.

Learning points:

MEN1 patients will develop parathyroid disease, which eventually will lead to surgical treatment with removal of the pathological glands.

Preoperatively usage of MRI combined with PET tracers such as 11C-methionine and 18F-Fluorocholine are able to detect parathyroid pathology with a higher sensitivity than conventional imaging.

Techniques using intraoperatively angiography with fluorescence and florescent dyes allow surgeons to verify the vascularization of each parathyroid gland.

Optimization of noninvasive preoperative imaging techniques and intraoperative fluorescent imaging are valuable tools and should be taken into consideration when performing PTX consecutively in the same patient to avoid postoperative complications.

The spotted hyaena (Crocuta crocuta) is a unique species, even amongst the Hyaenidae. Extreme clitoral development in female spotted hyaenas challenges aspects of the accepted framework of sexual differentiation and reproductive function. They lack a vulva and instead urinate, copulate and give birth through a single, long urogenital canal that traverses a clitoris superficially resembling a penis. Recent and historical evidence is reviewed to describe our changing understanding of the biology of this species. Expanding upon observations from hyaenas in nature, much has been learned from studies utilising the captive colony at the University of California, Berkeley. The steroid environment of pregnancy is shaped by placental androgen and oestrogen secretion and a late gestational increase in sex hormone binding globulin, the regulated expression and steroid-binding characteristics of which are unique within the Hyaenidae. While initial external genital development is largely free of androgenic influence, the increase in testosterone concentrations in late gestation influences foetal development. Specifically, anti-androgen (AA) treatment of pregnant females reduced the developmental influence of androgens on their foetuses, resulting in reduced androstenedione concentrations in young females and easier birth through a ‘feminised’ clitoris, but precluded intromission and mating by ‘feminised’ male offspring, and altered social interactions. Insight into the costs and benefits of androgen exposure on spotted hyaena reproductive development, endocrinology and behaviour emphasises the delicate balance that sustains reproductive success, forces a re-evaluation of how we define masculine vs feminine sexual characteristics, and motivates reflection about the representative value of model species.

Many diseases of the respiratory system occur differently in males and females, indicating a possible role of gonadal hormones in respiratory control. We hypothesized that testosterone (T) is important for the ventilatory chemosensitivity responses in males. To test this hypothesis, we evaluated ventilation (V̇E), metabolic rate and body temperature (Tb) under normoxia/normocapnia, hypercapnia and hypoxia in orchiectomized (ORX), ORX with testosterone replacement (ORX+T) or flutamide (FL, androgen receptor blocker)-treated rats. We also performed immunohistochemistry to evaluate the presence of androgen receptor (AR) in the carotid body (CB) of intact males. Orchiectomy promoted a reduction V̇E and ventilatory equivalent (V̇E/V̇O2) under room-air conditions, which was restored with testosterone treatment. Moreover, during hypoxia or hypercapnia, animals that received testosterone replacement had a higher V̇E and V̇E/V̇O2 than control and ORX, without changes in metabolic and thermal variables. Flutamide decreased the hypoxic ventilatory response without changing the CO2-drive to breathe, suggesting that the testosterone effect on hypercapnic hyperventilation does not appear to involve the AR. We also determined the presence of AR in the CB of intact animals. Our findings demonstrate that testosterone seems to be important for maintaining resting V̇E in males. In addition, the influence of testosterone on V̇E, either during resting conditions or under hypoxia and hypercapnia, seems to be a direct and specific effect, as no changes in metabolic rate or Tb were observed during any treatment. Finally, a putative site of testosterone action during hypoxia is the CB, since we detected the presence of AR in this structure.

The world in which we live is over brimming with chaos and turbulence. Unpredictability has become the order of the day. Everything around us seems to be in a state of continuous flux. We are trapped in the vortex of an unending cyclone of change. The very existence of human kind is in a state of dynamic equilibrium, so to say. We as a species are striving and struggling to survive in a world that can at best be summarily described by a four-letter acronym called VUCA (Volatile, Uncertain, Complex, Ambiguous). The world in general and the corporate world in particular needs to thinks about devising concrete strategies to overcome the challenges offered by these four dominant characteristic waves sweeping the environment. The paper aims to understand the volatility, uncertainty, complexity and ambiguity inherent in the environment in detail, to analyse the challenges offered by them and to finally explore the solutions to overcome these challenges.

Published: August 2020

Introducción: La artroplastia total de rodilla es el recurso terapéutico para pacientes con artrosis severa y gran incapacidad física. Sin embargo, muchos evolucionan con dolor y déficit funcional. En este estudio, se utiliza un tratamiento con movilización pasiva continua a partir de los 10 días de la cirugía. Materiales y Métodos: Se incluyó a 60 pacientes que fueron asignados, en forma aleatoria, a 2 grupos (30 en cada grupo). Al grupo 1 (G1, 23 mujeres) se le aplicó un protocolo de tratamiento convencional y, al grupo 2 (G2, 17 mujeres), el mismo programa y la adicción de un equipo de movimiento pasivo continuo a los 10 días de la intervención. Se evaluaron el dolor, la movilidad articular, la fuerza muscular y la función (WOMAC y prueba TUG). Resultados: No se observaron diferencias estadísticamente significativas en los parámetros estudiados, aunque sí una tendencia a la mejoría en el G2. En este grupo, la fuerza de extensión de la rodilla fue mayor y también hubo una correlación basal entre la fuerza y la prueba TUG. Conclusiones: El uso diferido de la movilización pasiva continua mejoró la fuerza de extensión de la rodilla y el rendimiento en la prueba TUG, aunque sin diferencias significativas entre ambos grupos. No se observaron efectos adversos. Nivel de Evidencia: I
Usos e desusos do parque urbano em escala metropolitana: um estudo do perfil dos usuários do Parque Tejo em Lisboa (Portugal)
Authors: Gomes Marcos Antônio Silvestre , Oliveira Jonatan Alexandre de
Published: August 2020

Os parques compõem agendas urbanas como espaços que legitimam o compromisso ambiental e social. No entanto, é comum que esses espaços sejam projetados em áreas de grande interesse imobiliário, como ocorreu com o Parque Tejo, na cidade de Lisboa. Neste trabalho, analisa-se a sua implantação, entre 1995 e 1999, como parte de um projeto urbanístico mais amplo denominado Parque das Nações, para sediar a Exposição Mundial de Lisboa de 1998. O Parque Tejo ocupou uma área com elevado nível de degradação ambiental, contribuindo para a projeção de uma Lisboa moderna e competitiva no mercado global de cidades. A análise aprofunda o debate da proposta de um parque em escala metropolitana, cujos usos atenderia a um público diverso social e espacialmente. O artigo destaca aspectos das suas infraestruturas e do perfil dos seus usuários, que coadjuva para uma leitura dos usos e apropriações e também como um caminho metodológico para estudos de diferentes realidades. Destarte, os resultados apontam as características de adorno ao Parque das Nações, de lazer contemplativo, sem diversidade de equipamentos, o que tem limitado seus usos e funções.Ideias destacadas: artigo de investigação sobre os parques e agenda global da sustentabilidade urbana. A dimensão política e econômica na implantação de parques urbanos. Produção e apropriação dos espaços públicos.
Las relaciones sociales en el sector agropecuario pampeano argentino: análisis de los diferentes tipos de sujetos agrarios a partir de los modos en que construyen sus vínculos en la producción
Authors: Moreno Manuela
Published: August 2020

En el contexto de las profundas transformaciones que atraviesan al sector agropecuario de la región pampeana argentina en la actualidad, se analiza de qué modo se han redefinido y cuáles son las características centrales de las relaciones sociales entre los actores involucrados en la producción. El principal objetivo de este artículo es mostrar cómo los distintos tipos de relaciones resultan un elemento clave para la caracterización de los sujetos sociales agrarios actuales. Para ello se trabajó con una muestra de 38 explotaciones agropecuarias de distinto tamaño y perfil en tres partidos de la provincia de Buenos Aires (perteneciente a la región pampeana). A partir de entrevistas semiestructuradas a productores agropecuarios y otros actores involucrados, se reconstruyeron los tipos de estructuras de relaciones sociales en la esfera de la producción, y los tipos de lógicas con las cuales manejan la producción. Mediante este análisis, se identificó una tendencia a la mercantilización de las relaciones sociales en el agro, pero que se encuentra limitada en su plena expansión por la persistencia de una lógica que combina un anclaje en los parámetros científicos y de mercado, con una valorización de las trayectorias y saberes locales e históricos de cada espacio productivo.Ideas destacadas: artículo de investigación que aborda las transformaciones recientes en el agro pampeano argentino, y muestra cómo se reconfiguran las relaciones sociales en la actualidad. Mediante un análisis empírico en tres partidos de la provincia de Buenos Aires y de entrevistas en profundidad a productores agropecuarios, se identifica la coexistencia de distintos tipos de vínculos, y se subraya que la dimensión relacional resulta central para profundizar en el análisis de los sujetos agrarios y caracterizarlos.

Este artículo presenta un análisis teórico del paradigma de los sistemas complejos para el estudio del turismo, y aborda la complejidad que atraviesa los modelos de dicho estudio. A partir de una revisión, el objetivo propuesto fue realizar un diagnóstico diferenciado en dos localidades: Santa Fe de Antioquia (Colombia) y Malinalco (México). Para alcanzar dicho objetivo se utilizó la metodología del turismo armónico (META), ya que esta surge de la discusión teórica e incorporación de atributos de la sustentabilidad para explicar el turismo como parte de un sistema complejo. De allí que se obtuvo la caracterización del sistema en cada una de las localidades mencionadas, a partir de las variables que comprende la META. Como principales resultados se analizan similitudes entre las dos localidades y una fuerte evolución de la actividad turística, elemento que incide en el desarrollo local y que ha propiciado discusiones sobre la metodología y la aplicación de los conceptos en la practicidad.Ideas destacadas: artículo de investigación que analiza los atributos de la sustentabilidad como parte del sistema complejo, para generar una caracterización que considera las variables del modelo de turismo armónico (META) en dos localidades: Santa Fe de Antioquia, Colombia y Malinalco, México.
