MamĂĄ AvĂł, escrito por la docente y escritora Yesenia Escobar Espitia, con ilustraciones de Alexis Barroso
Londoño, es un bello cuento que relata la historia de una niña y su abuela, quienes encuentran en el peinado un hermoso vĂnculo con sus raĂces, al ser el espacio en el que la abuela transmite a su nieta, mediante cantos e historias, toda la grandeza y prodigalidad de su cultura
La construcciĂłn de un proyecto etnoeducativo de comunidades negras en el pacĂfico colombiano
Las reflexiones contenidas en el presente ensayo pretenden realizar un anĂĄlisis de los procesos educativos que se desarrollan en el PacĂfico colombiano, los cuales intentan construir, desde una perspectiva Ă©tnica, una educaciĂłn pertinente y acorde a las caracterĂsticas culturales, socioeconĂłmicas y ambientales de la regiĂłn. Estos procesos etnoeducativos, como espacios de revalorizaciĂłn de la cultura propia y de afirmaciĂłn de la identidad Ă©tnica como sujetos individual y colectivo, se basan en..
The phenolic compounds, tocopherols, and phytosterols in the edible oil of guava (Psidium guava) seeds obtained by supercritical CO<sub>2</sub> extraction
An edible oil was obtained from guava seeds by supercritical CO2 extraction. The oil was characterized by its fatty acid composition, physicochemical properties, and the contents of phenolic, miscellaneous, phytosterol, and tocopherol compounds. The oil, obtained with a yield of 8.6 ± 1.2 g oil/100 g guava seeds, had a high content of linoleic acid (78.5 %, w/w), followed by that of oleic acid (13.8 %, w/w). The guava seed oil had physicochemical properties comparable to those published in previous research, except for the low stability to oxidation. The chromatographic profile of the phenolic and miscellaneous compounds was dominated by vanillin (9.6 ± 0.3 mg/100 g oil) and cinnamaldehyde (9.4 ± 0.2 mg/100 g oil), followed by vanillic acid (3.9 ± 0.4 mg/100 g oil), cinnamic acid (2.4 ± 0.1 mg/100 g oil), and minor amounts of other phenolic aldehydes. Among the phytosterols and tocopherols, ÎČ-sitosterol (1048.9 ± 48.4 mg/100 g oil) and Îł-tocopherol (82.6 ± 3.7 mg/100 g oil) were the most abundant. The low oxidative stability of the oil compared to that published in previous reports might reflect the high complexity of this matrix. This oil might have applications, directly or after blending with more stable edible oils.</p
La CĂĄtedra de Estudios Afrocolombianos CEA en BogotĂĄ : avances, retos y perspectivas
La CĂĄtedra de Estudios Afrocolombianos (CEA), adoptada en el artĂculo 39 de la Ley 70 de 1993, y reglamentada mediante el Decreto 1122 de 1998, se constituye en una estrategia pedagĂłgica y curricular orientada al reconocimiento de la historia y las culturas afrocolombianas, asĂ como a la eliminaciĂłn del racismo y la discriminaciĂłn racial en la escuela. En ese sentido, el Ministerio de EducaciĂłn Nacional ha formulado los lineamientos curriculares que orientan la implementaciĂłn de la CĂĄtedra en el nivel nacional. En este marco, la SecretarĂa de EducaciĂłn del Distrito (SED) de BogotĂĄ, ha impulsado la implementaciĂłn de la CEA, para lo cual expide la ResoluciĂłn 1961 de 2007 âPor la cual se fortalece la CĂĄtedra de Estudios Afrocolombianos en BogotĂĄâ. AsĂ, la CĂĄtedra cuenta con una trayectoria en el sistema educativo distrital y encuentra en el Plan de Desarrollo Distrital âBogotĂĄ Humana 2012-2016â un escenario propicio para su fortalecimiento, acorde con el objetivo de mejorar las condiciones de vida de los habitantes de la capital, reduciendo la segregaciĂłn y discriminaciĂłn, lo cual se traduce en una polĂtica educativa distrital que busca garantizar el derecho a una educaciĂłn de calidad, desde un enfoque diferencial, para los grupos Ă©tnicos afrocolombianos, palanqueros, raizales, indĂgenas y rom
PsicologĂa en contexto: retos y desafĂos para los investigadores
La investigaciĂłn ha ocupado un lugar central en la Facultad de PsicologĂa de la Universidad de San Buenaventura Cali. Desde su creaciĂłn hasta la fecha, la Facultad ha asumido una perspectiva crĂtica de la disciplina, con la intenciĂłn explĂcita de promover un ejercicio profesional reflexivo y ajustado a las necesidades y caracterĂsticas de nuestro contexto colombiano.
Se trata, por supuesto, de una tarea interminable que solo puede llevarse a cabo por los senderos del diĂĄlogo y la discusiĂłn. El Primer Encuentro Regional de PsicologĂa se gestĂł con ese fin y este volumen condensa las ponencias presentadas en dicho encuentro, el 20 de septiembre del 2012. Los trabajos incluyen avances y resultados de investigaciĂłn, asĂ como ponencias de reflexiĂłn teĂłrica. El evento contĂł con la participaciĂłn de estudiantes y docentes, asĂ como de algunas ONG de la regiĂłn. TambiĂ©n nos acompañaron como invitados internacionales, la profesora Amelia HaydĂ©e Imbriano (Argentina) y el profesor Jorge Juan RomĂĄn (Cuba).Universidad de San buenaventura - Cal
Engendrando desenvolvimento e etnicidade nas terras baixas do PacĂfico colombiano Ser y tener: engendering development and ethnicity in the Pacific lowlands of ColĂŽmbia
Neste ensaio, exploro como as organizaçÔes e redes de mulheres afro-colombianas moldam e sĂŁo moldadas por iniciativas do Estado para desenvolver e modernizar a regiĂŁo do PacĂfico. Argumento que, agindo assim, elas mobilizam e vĂŁo alĂ©m da retĂłrica desenvolvimentista do Estado e do discurso de uma etnia negra 'gendrada' e da tradição das organizaçÔes polĂticas negras da regiĂŁo.<br>In this paper I explore how Afro-Colombian women's organizations and networks shape and are shaped by state initiatives to develop and modernize the Pacific region. I argue that in doing so these mobilize and go beyond the developmentalist rhetoric of the state and the discourse of gendered black ethnicity and tradition of black political organizations in the region
Evaluation of a quality improvement intervention to reduce anastomotic leak following right colectomy (EAGLE): pragmatic, batched stepped-wedge, cluster-randomized trial in 64 countries
Background
Anastomotic leak affects 8 per cent of patients after right colectomy with a 10-fold increased risk of postoperative death. The EAGLE study aimed to develop and test whether an international, standardized quality improvement intervention could reduce anastomotic leaks.
Methods
The internationally intended protocol, iteratively co-developed by a multistage Delphi process, comprised an online educational module introducing risk stratification, an intraoperative checklist, and harmonized surgical techniques. Clusters (hospital teams) were randomized to one of three arms with varied sequences of intervention/data collection by a derived stepped-wedge batch design (at least 18 hospital teams per batch). Patients were blinded to the study allocation. Low- and middle-income country enrolment was encouraged. The primary outcome (assessed by intention to treat) was anastomotic leak rate, and subgroup analyses by module completion (at least 80 per cent of surgeons, high engagement; less than 50 per cent, low engagement) were preplanned.
Results
A total 355 hospital teams registered, with 332 from 64 countries (39.2 per cent low and middle income) included in the final analysis. The online modules were completed by half of the surgeons (2143 of 4411). The primary analysis included 3039 of the 3268 patients recruited (206 patients had no anastomosis and 23 were lost to follow-up), with anastomotic leaks arising before and after the intervention in 10.1 and 9.6 per cent respectively (adjusted OR 0.87, 95 per cent c.i. 0.59 to 1.30; P = 0.498). The proportion of surgeons completing the educational modules was an influence: the leak rate decreased from 12.2 per cent (61 of 500) before intervention to 5.1 per cent (24 of 473) after intervention in high-engagement centres (adjusted OR 0.36, 0.20 to 0.64; P < 0.001), but this was not observed in low-engagement hospitals (8.3 per cent (59 of 714) and 13.8 per cent (61 of 443) respectively; adjusted OR 2.09, 1.31 to 3.31).
Conclusion
Completion of globally available digital training by engaged teams can alter anastomotic leak rates. Registration number: NCT04270721 (http://www.clinicaltrials.gov)
