Published: September 2016

ABSTRACT Increased grain yield can be obtained via an interaction between plants and growth-promoting microorganisms. The Bradyrhizobium spp. are capable of fixing atmospheric nitrogen in soybeans [Glycine max (L.) Merril], and Azospirillum spp. induce the synthesis of phytohormones. The aim of this study was to evaluate inoculation with Bradyrhizobium and co-inoculation with Bradyrhizobium + Azospirillum brasilense in soybeans in combination with the application a topdressing of 0, 75 or 150 kg of N ha-1 of urea during the reproductive stage. Three soybean cultivars (BMX Ativa, TEC 6029 and BMX Potência), were tested in field experiments in Santa Maria, RS, Brazil, during two agricultural years (2013/2014 and 2014/2015) and two sowing times. Morphological, nodulation and yield components were evaluated. Co-inoculation increased the grain yield by 240 kg ha-1 compared with conventional inoculation. When co-inoculated, cultivars BMX Ativa, TEC 6029 and BMX Potência showed increased grain yields of 6, 4 and 12%, respectively. The application of 150 kg ha-1 of N as a topdressing increased the grain yield by 300 kg ha-1 in the co-inoculated cultivars TEC 6029 and BMX Potência, but without a financial return. When inoculated only with Bradyrhizobium, the cultivars did not respond positively to the application of urea.

Published: September 2016

ABSTRACT Biodegradable packaging may replace non-biodegradable materials when the shelf life of the packaged product is relatively short, as in minimally processed foods. The objective of this work was to evaluate the efficiency of biodegradable films comprising starch/polyvinyl alcohol (PVOH)/alginate with the addition of 0 or 0.5% of essential oil of copaiba (EOCP) or lemongrass (EOLM) compared to poly-vinyl chloride (PVC) films in the storage of minimally processed lettuce. Lettuce samples cut into 1-cm strips were placed in polypropylene trays wrapped with biodegradable films and stored at 6 ± 2 °C for 8 days. PVC films were used as controls. The biofilms presented 11.43-8.11 MPa resistance and 11.3-13.22% elongation, with water vapor permeability (WVP) of 0.5-4.04 x 10-12 g. s-1.Pa-1.m-1; thus, the films' properties were considered suitable for the application. The lettuce stored in PVC presented minor total soluble solids (TSS), less luminosity (L), higher intensity of yellow color (b), and eight times less mass loss than that stored in biodegradable films. Multivariate analysis showed that the lettuce lost quality after 2 days of storage in PVC films, representing a different result from the other treatments. Lettuce stored in biodegradable films for 2 and 4 days showed a greater similarity with newly harvested lettuce (time zero). The films with or without the addition of essential oil showed similar characteristics. Biodegradable films were considered viable for the storage of minimally processed lettuce.

Published: September 2016

ABSTRACT Objectives: to describe the feelings and perceptions resulting from gynecologic surgery by women and analyze how they experience the changes caused by the surgery. Method: a qualitative, descriptive and exploratory study, which had Symbolic Interactionism and Grounded Theory as its theoretical framework. Participants of the study: 13 women submitted to surgery: Total Abdominal Hysterectomy, Total Abdominal Hysterectomy with bilateral Adnexectomy, Wertheim-Meigs surgery, Oophorectomy, Salpingectomy, Mastectomy, Quadrantectomy and Tracheloplasty. Individual interviews were conducted, recorded and analyzed according to the comparative analysis technique of the Grounded Theory. Results: from the data two categories emerged - Perceiving a different body and feeling as a different person and; building the meaning of mutilation. The changes experienced make women build new meanings and change the perception of themselves and their social environment. From the interaction with their inner self, occurred a reflection on relationships, the difference in their body and themselves, the functions it performs and the harm caused by the surgery. Conclusions: the participants felt like different women; the mutilation developed in concrete feelings, due the loss of the organ, and in abstract, linked to the impact of social identity and female functionality. The importance of the nurse establishing a multidimensional care, to identify the needs that go beyond the biological body is perceived.

O Estudo das Práticas Performativas na Perspectiva de uma Antropologia da Estética
Authors: Garrabé Laure
Published: September 2016

RESUMO Este texto propõe uma contribuição ao estudo das práticas performativas a partir de uma apreensão antropológica na qual a estética, entendida como aisthesis, se estabelece como hermenêutica das formas de socialização e de individuação em ato no fenômeno estudado. Apresenta-se um aparelho epistemológico no qual as noções de ritmo e de relação, átomos irredutíveis de toda forma de estética, teriam valor paradigmático. Através delas, discute-se a possibilidade de apreender os modos de produção, de recepção e de apropriação, caracterizando formas de práxis cujos graus de construção (da ação, da experiência e dos imaginários) e de intencionalidade são as variáveis que determinam a singularidade e a inserção dessas formas em dispositivos (da arte) socialmente reconhecidos.

Published: September 2016

Abstract OBJECTIVE To understand the nursing professionals' conceptions of teamwork and their elements. METHOD A qualitative study conducted in an oncological hospital using a semi-structured interview with 21 nursing professionals. RESULTS Two conceptions emerged from the accounts: teamwork restricted to nursing professionals and teamwork with interprofessional collaboration with particular importance for interactive dimensions: communication, trust and professional bonds, mutual respect and recognition of the other's work, collaboration, and conflict, with this last subcategory considered as an obstacle to teamwork. CONCLUSION Nursing conceives teamwork as an interprofessional practice, which is a result of the quality of interaction among professionals from different areas and involves the recognition and handling of conflicts.
La Noción de Evaluación Eudaimonista en la Teoría Cognitiva de las Emociones de Martha Nussbaum
Authors: Gil Marta
Published: September 2016

RESUMEN: En este artículo se presenta la evaluación eudaimonista como una articulación entre el agente y los objetos del mundo. Sostendremos que, gracias a esta noción, la teoría de las emociones de Nussbaum es adecuada para dar cuenta de la función adaptativa de las emociones, por lo que las teorías no cognitivas no resultarían superiores en este aspecto. Esta noción serviría, asimismo, para no dejar de lado los aspectos cognitivos de la emoción. Veremos cómo las ideas de Nussbaum se basan en las de las teorías evaluativas provenientes de la psicología, para después desplegar su propuesta en detalle. En la exposición, también trataremos otras cuestiones, entre ellas, la racionalidad de las emociones, la relación entre éstas y el florecimiento humano, o la vinculación de las mismas con nuestra condición vulnerable.
Thought Experiment Analyses of René Descartes' Cogito
Authors: Hertogh C. P.
Published: September 2016

ABSTRACT: René Descartes' Cogito is an example of a paradigmatic thought experiment, herald of both subjectivism and new science in Europe's Modern Age, that seems to have escaped the attention of thought experiment philosophers. On deep analysis, the Cogito appears as universal instantiation (or modus ponens with implicit major 'whatever has the property of thinking, exists'). The Cogito has strong rhetorical effects for it narratively generalizes from I to all human kind, and its historical and philosophical success can be explained from its concise enthymematic structure that rings true in many possible senses. We consider it a preeminent example of a thought experiment as it states the power of thinking as its very contents. From Descartes' methodology of doubt we can conclude that, e.g., on a Wittgensteinian interpretation, the Cogito is a logical thought experiment rather than a psychological one.

Published: September 2016

Copolymers of methoxy polyethyleneglycol (meth)acrylate (mPEG(M)A) and 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS) were synthesised, characterised with Fourier transform infrared spectroscopy and gel permeation chromatography, and the effects of molecular architecture on the properties of cement-based systems were investigated. Superplasticiser (SP) adsorption was determined with a total organic carbon analyser, while spread and mechanical properties were assessed according to European standards. The rheological behaviour of cement pastes at different copolymer dosages was also studied. Sufficient fluidity and fluidity retention over time are requirements for the mixing, transportation, pumping and moulding of concrete at construction sites. The synthesised SPs with long side chains provided mortars with high fluidity, high dispersing power per adsorption ratio and low mechanical strength compared with the SPs with short side chains. They were also effective at decreasing the shear yield stresses and plastic viscosities (at high dosages) of the cement pastes. Additionally, mortars dosed with mPEG(M)A-co-AMPS had higher fluidity and fluidity-retaining properties compared with mortars prepared with lignosulfonate-type SP.
Lats1/2 Regulate Yap/Taz to Control Nephron Progenitor Epithelialization and Inhibit Myofibroblast Formation
Authors: McNeill Helen , Reginensi Antoine
Published: September 2016

In the kidney, formation of the functional filtration units, the nephrons, is essential for postnatal life. During development, mesenchymal progenitors tightly regulate the balance between self-renewal and differentiation to give rise to all nephron epithelia. Here, we investigated the functions of the Hippo pathway serine/threonine-protein kinases Lats1 and Lats2, which phosphorylate and inhibit the transcriptional coactivators Yap and Taz, in nephron progenitor cells. Genetic deletion of Lats1 and Lats2 in nephron progenitors of mice led to disruption of nephrogenesis, with an accumulation of spindle-shaped cells in both cortical and medullary regions of the kidney. Lineage-tracing experiments revealed that the cells that accumulated in the interstitium derived from nephron progenitor cells and expressed E-cadherin as well as vimentin, a myofibroblastic marker not usually detected after mesenchymal-to-epithelial transition. The accumulation of these interstitial cells associated with collagen deposition and ectopic expression of the myofibroblastic markers vimentin and α-smooth-muscle actin in developing kidneys. Although these myofibroblastic cells had high Yap and Taz accumulation in the nucleus concomitant with a loss of phosphorylated Yap, reduction of Yap and/or Taz expression levels completely rescued the Lats1/2 phenotype. Taken together, our results demonstrate that Lats1/2 kinases restrict Yap/Taz activities to promote nephron progenitor cell differentiation in the mammalian kidney. Notably, our data also show that myofibroblastic cells can differentiate from nephron progenitors.
Mujeres en bicicleta. Imaginarios, prácticas y construcción social del entorno en la ciudad de Sevilla
Authors: Huerta Elena , Gálvez Cristina
Published: September 2016

El uso de la bicicleta como medio de transporte urbano está demostrando poseer un importante potencial para modificar algunas piezas fundamentales de un modelo de movilidad insostenible pero aún dominante. Sin embargo y a pesar de su creciente presencia en el paisaje urbano, desplazarse en bicicleta no termina de ser la mejor opción para determinados grupos o perfiles de población. La ciudad de Sevilla se presenta como un caso interesante para abordar esta cuestión. En muy pocos años y tras la implantación de distintas medidas de fomento, entre las que resultó clave la ejecución de la red de vías ciclistas, se produjo un importante incremento en el número de usuarios/as de la bicicleta, al tiempo que se han ido desplegando una serie de procesos socioculturales asociados a la integración de la misma en la ciudad. Sin embargo, a pesar del boom ciclista, solo en torno al 35% de quienes la utilizan para sus desplazamientos cotidianos son mujeres. Si bien en los últimos años se está produciendo un incremento de este colectivo, encontramos importantes contrastes en base a determinados perfiles, edades, horarios y zonas de la ciudad.
Childhood in a changing world
Authors: Polivanova K.N.
Published: September 2016

The article presents a psychological and socio-cultural analysis of contemporary childhood. It shows that in modern conditions the development of society necessitates scholars to expand the scope of analysis of childhood beyond psychological paradigm. The processes of diversification become more evident, increasing the number of recognized patterns of childhood, which cannot be evaluated from the standpoint of the norm. From the point of view of methodology it means that we need to broaden the view of childhood and take into account the analysis of social and cultural contexts. The article shows that the view of a child as a future adult (childasbecoming)should be replaced by the view of a child at present time (child as being)

Published: September 2016

Pesquisadores de diferentes áreas, interessados especialmente em estratégia, têm dedicado a atenção de suas agendas de pesquisa para compreender a orientação empreendedora dos gestores e seus desdobramentos. Neste contexto surgem as capacidades dinâmicas, como sendo a habilidade interna da organização para se projetar em relação ao ambiente externo e, com isto, obter melhores desempenhos. Desta forma, objetiva-se com a presente pesquisa correlacionar a orientação empreendedora com as capacidades dinâmicas: gerencial, mercadológica e ambidestra de agroindústrias do Rio Grande do Sul (RS), Brasil. A metodologia sustenta-se na pesquisa quantitativa e na técnica survey, sendo analisadas 14 agroindústrias representativas de diferentes regiões do RS. Foram empregadas diferentes técnicas estatísticas. Os resultados apontaram que a orientação empreendedora possui relação positiva com a capacidade mercadológica e ambidestra. Não foi possível confirmar a relação com a capacidade gerencial. Assim, identificou-se que as ações empreendedoras dos gestores possuem ligação com a busca pelo atendimento e antecipação das demandas dos clientes, além da criação de novos produtos/serviços em consonância com a melhoria dos já criados, de maneira constante e equilibrada. Estes achados demonstram uma característica peculiar das agroindústrias familiares, o conhecimento de seus clientes e a busca pela diferenciação com produtos que agregam valor, fortalecendo as relações entre o rural e o urbano. A ampliação dos produtos ofertados demonstra a preocupação das agroindústrias com as relações de comercialização, fazendo com que as práticas agrícolas recebam reconhecimento como negócio e contribuam para sustentabilidade e qualidade de vida no meio rural.

This paper presents an experimental research of identification method proposed by the authors in their previous works. The method was developed to identify a linear observation model in remote sensing images. It uses the relation between energy spectra of input and output images, and it is called energy spectrum method. The latest modification of the method applies vector map data from geoinforation system to construct an image with energy spectrum similar to energy spectrum of unknown undistorted image. Vector map and input image had been supposed to be exactly spatially coherent. In this paper the algorithm’s quality is investigated in case of inexact spatial matching of input image and vector map. Accuracy of input image georeference and accuracy of vector map borders are considered as major spatial mismatch factors. Experimental evaluation of the these factors influence on quality of impulse response restoration is provided.

The paper presents a mathematical model of a piston compressor which is part of nitrogen-oxygen gas generator. Taking into account the structural parameters of the compressor, as well as the suction and pressurization valves, such model allows to obtain the dynamics of the pressure amplitude under the compressor’s piston together with the vibration velocity and vibration acceleration that are transmitted in the form of mechanical affections to the equipment (such mechanical affections can be observed using the corresponding sensors). Also we investigate the pseudo-spectra of vibration signals using the MUSIC algorithm for the set of parameters of compressor’s model (such parameters determine the evolution of a defect).

A neuron is an electrically excitable cell that processes and transmits information through electrical and chemical signals. Neurons connect and pass signals to other cells through the structure called synapse. We focus on synapses through which the signals are transferred by signaling molecules called neurotransmitters. One of the predominant excitatory neurotransmitters in the central nervous system of the mammals, including humans, is glutamate. It is directly or indirectly involved in most brain functions. However, the excessive stimulation of the glutamate receptors is toxic to neurons, therefore it is important to rapidly clear the glutamate from the extracellular space and keep its concentration low. Glutamate transporters play a crucial role in regulating glutamate concentration in synaptic clefts. Thus, it is important to understand the mechanisms underlying this process. We describe measurement of the glutamate concentration in the extracellular space. It is important to estimate the baseline glutamate concentration to use it in future models and studies. However, two existing methods of measuring the glutamate concentration in the extracellular space give inconsistent results with about 100 fold difference. We construct the model of the process of the glutamate concentration measurement in order to explain that discrepancy.

The influence of the initial surface condition on the intensity of porous structure formation in a metallic material during laser action has been determined. Two groups of samples were studied: Cu-Zn alloy with and without the oxide layer. Surface morphology of the samples has been researched using electron microscopy. The centre area of laser treatment zone on the surface of the samples is heated up to ≥500ºC not less than 180 s. At that, a porous structure with an irregular distribution of pores on the surface appears. Removing the oxide film by mechanical treatment leads to significant improvement of conditions of pore formation on the surface of the metal samples in the case of laser treatment. Consequently, a structure with a uniform pore distribution appears. After that, the temperature in the centre of the heat-affected zone increases to 500ºC for 12–20 s. This leads to a significant increase of pore formation intensity. In the case of using the obtained material as a catalyst, an increase of its specific surface area allows for the improvement of conditions for hetero-phase chemical and catalytic reactions, which increases the productivity of the catalytic actions.

Authors: Correa García Jaime Andrés , Arango Serna Martín Darío , Álvarez Uribe Karla Cristina
Published: September 2016

Este artículo propone lineamientos para iniciar el camino de la definición y estructuración de una metodología para la valoración de los proyectos de transferencia tecnológica universitaria, puesto que la misión actual de las universidades se revalúa y trasciende más allá de la docencia, la investigación y la extensión. Actualmente, se requiere que la Universidad transfiera el conocimiento y los resultados de la acumulación de capital intelectual en beneficio de la sociedad. Igualmente, se desarrolla con relación a la valoración de los proyectos de transferencia tecnológica universitaria una metodología que facilite realizar los esquemas de transferencia existentes y los modelos de valoración del capital intelectual.
Responsabilidad social empresarial en la dimensión laboral: caso Bancolombia y BBVA
Authors: Duque Orozco Yenni Viviana , Martínez Barón Deissy
Published: September 2016

Se construyó una matriz interpretativa que permitió evidenciar las prácticas en el ámbito laboral tomando como referente las propuestas por el Suplemento sobre el Sector de Servicios Financieros del Global Reporting Initiative- GRI. Los resultados muestran en ambos casos una fuerte preocupación en los aspectos de formación, salud y seguridad laboral; sin embargo, la brecha salarial entre hombres y mujeres, y la inexistente participación de las minorías son aspectos que aún no han superado. Las diferencias entre las dos entidades radican en las relaciones empresa- trabajadores y los beneficios sociales directos en forma de contribución monetaria.
Efectos del debido proceso en la formulación de la NIIF 13: mediciones a valor razonable
Authors: Arias Bello Martha Liliana , Salazar Edgar Emilio
Published: September 2016

La NIIF 13 es el resultado de un extenso período de deliberación y socialización de planteamientos, orientados a definir los criterios de las mediciones a valor razonable. Esta norma surge en el proceso de convergencia adelantado entre IASB y FASB, como respuesta a una necesidad de homogeneizar las bases de esta medición, dado que su aplicación es transversal en el conjunto de Normas Internacionales de Información Financiera. Para tal fin, el debido proceso se convierte en un mecanismo para legitimar las prácticas que se esperan sean de aplicación universal. El presente documento analiza la evolución de los planteamientos conceptuales y técnicos de la NIIF 13, a partir de los desarrollos evidenciados desde el borrador de discusión de 2006. Como resultado, se evidencian los efectos derivados del debido proceso en las premisas que finalmente quedaron incorporadas en la norma definitiva

Published: September 2016

El objetivo del siguiente trabajo es generar un ranking a partir de los datos consultados del 2009 de los Ministerios de Economía y Hacienda o en su caso de Finanzas de los países de Iberoamérica más transparentes en divulgar información económico-financiera a nivel on-line. Para ello, se propone como propuesta metodológica un cuestionario e índices de transparencia de la divulgación de información en el entorno económico y financiero. Entre los principales hallazgos, podemos mencionar que los Ministerios de México, España y Chile salieron como los mejores valorados, sin embargo, Panamá y Honduras fueron los menos transparentes en divulgar dicha información

ermina el año 2011 con un hito en la historia de la educación en nuestro país, la suspensión y retiro temporal del documento de Reforma integral al sistema de educación superior por parte del gobierno, luego de la participación activa de estudiantes, profesores y administradores educativos, lo que significó una movilización social amplia en torno a esta iniciativa. Este debate hizo que el periodo 2011 pueda ser recordado como aquel en el que diversas fuerzas y agentes se re-encontraron alrededor de la necesidad de expresar nuevamente sus posiciones y de hacer a la Universidad un lugar habitable y reflexivo, como le corresponde ser. En este marco, jugaron un papel interesante los administradores administrativos, tanto como difusores y críticos de la reforma, lo que permite hacer la siguiente reflexión orientada al papel de estos agentes del sistema. En esa misma línea, este espacio es también la oportunidad para agradecer a quien hizo de este especio un lugar de encuentro, reflexión y discusión de las ideas, que hoy día se reconoce como una ventana en las disciplinas económicas de nuestro medio.
Generación de ingresos y gerencia de recursos desde la economía pública territorial en Colombia
Authors: Gutiérrez Ossa Jahir Alexander
Published: September 2016

Este artículo analiza la capacidad de generación de ingresos y gerencia de recursos de los entes territoriales, más allá de la estructura fiscal y presupuestal atada a la Ley 617 de 2000 (Presupues-tal), la Ley 715 de 2001 (de Transferencias), la Ley 819 de 2003 (Responsabilidad Fiscal) y el Acto Legislativo 05 de 2011 (de Regalías). Se evidencia que el Estado central cuestiona el patrón de dependencia de los entes territoriales de los recursos girados por la nación, por el letargo provocado en su estructura fiscal y presupuestal. Para el análisis se considera la economía pública territorial, la cual permite contextualizar el asunto desde el esfuerzo fiscal y la estructura presupuestal. Se concluye que falta armonizar la estructura de la economía pública de los entes territoriales con miras a establecer un orden lógico de interacción con las expectativas fiscales y presupuestales centrales, sin desconocer lo problemático que es la generación de rentas y tributos territoriales.
Caracterización de la pobreza oculta y su efecto en la sostenibilidad económica de las pequeñas y medianas empresas de la localidad de Usaquén (Bogotá - Colombia)
Authors: Mendoza Torres Martha Ruth , Tarazona Morales Orlando , Duque Vargas Lucero
Published: September 2016

El propósito de este artículo es mostrar los resultados de la investigación realizada en la localidad de Usaquén, la cual caracterizó la pobreza oculta o empobrecimiento de los hogares de clases media y alta, fenómeno que ha generado cambios en hábitos de compra y consumo, produciendo diferentes tipos de impacto en la sostenibilidad económica de las pequeñas empresas del sector. Para esto se seleccionaron dos poblaciones de estudio en la localidad: hogares de estratos 3, 4 y 5 y empresas pequeñas y medianas. Como metodología se utilizó la triangulación propuesta por Okuda & Gómez (2005), consistente en la aplicación de métodos cualitativos, entrevistas y grupos focales, y métodos cuantitativos, muestreo por conglomerados para aplicación de encuestas, que fueron procesadas mediante SPSS® Versión 14. Se encontró que efectivamente los hogares en estado de pobreza oculta han tenido cambios en sus hábitos de compra, ante los cuales las empresas han desarrollado estrategias adaptativas para preservar sus utilidades, como el desarrollo de nuevos servicios y el aumento del surtido de productos, para responder a los cambios de la demanda derivados de este tipo de pobreza, en aras de garantizar su sostenibilidad económica.

El volumen XIX de nuestra publicación es una bella oportunidad para re-encontrarnos y re-conocer el trabajo que toda una comunidad viene realizando. La Revista Facultad de Ciencias Económicas no es solo de la Universidad Militar Nueva Granada, sino también de todos aquellos colaboradores y colaboradoras que desde distintas instituciones ayudan a que este proyecto editorial crezca y madure. En este largo camino nos hemos topado con diversas voces, algunas de felicitación, otras críticas, pero todas cargadas de buena energía. Es por ello que no podemos dejar pasar las recientes discusiones sobre las necesarias, y no tan necesarias reformas a la Educación Superior en Colombia. En últimas, nuestros productos, son los productos de la universidad colombiana y latinoamericana. Esto nos obliga a reflexionar sobre ¿qué somos? y ¿qué papel jugamos en tal realidad?
Determinantes y consecuencias del trabajo infantil: un análisis de la literatura
Authors: Acevedo González Karina , Quejada Pérez Raúl , Yánez Contreras Martha
Published: September 2016

El presente artículo presenta los resultados de una revisión sistemática de la literatura que analiza uno de los fenómenos más complejos del mercado laboral: el trabajo infantil. El ejercicio muestra que los mayores desarrollos teóricos y empíricos se concentran en el estudio de la relación entre el trabajo de los menores y las variables de capital humano, en especial, la educación y la salud; relaciones complejas debido a que no existe una contundente evidencia de los efectos negativos del trabajo de los niños sobre estas variables. El documento destaca que con los desarrollos más recientes de la literatura se han desvirtuado hipótesis como el "luxury axiom", que atribuye el problema a la pobreza, y aparecen enfoques más amplios que incluyen los efectos de los mercados imperfectos, las migraciones y los programas de transferencias sobre el fenómeno de estudio.
Contabilidad para la equidad y la inclusión social: propuestas para una investigación interdisciplinaria a largo plazo
Authors: Rueda Delgado Gabriel
Published: September 2016

Colombia transita hacia la convergencia internacional, hacia un conjunto único de prácticas de reconocido valor técnico y aceptación a nivel mundial. Sin embargo, lejos de contribuir a la solución de problemas de la estructura económica y social del país, la adopción de dichas prácticas beneficiaría solo a algunos agentes contribuyendo a mantener invisibles, las necesidades de otros grupos sociales no necesariamente vinculados al mercado. El presente documento prepone adelantar actividades de investigación de largo aliento, que, a partir de reconocer los alcances y condiciones de la contabilidad, acuda a otras disciplinas para el estudio de alternativas teóricas y aplicadas para aportar soluciones a la aguda situación social y económica por la que atraviesa el país. El documento aporta diagnósticos y plantea alternativas conceptuales y metodológicas que inviten a la comunidad contable del país a hacer aportes para comprender y explicar el papel que la contabilidad puede jugar en nuestro entorno nacional sin desconocer los procesos de globalización.
