Complexity science and its methodological applications have increased in popularity in social science during the last two decades. One key concept within complexity science is that of self-organization. Self-organization is used to refer to the emergence of stable patterns through autonomous and self-reinforcing dynamics at the micro-level. In spite of its potential relevance for the study of social dynamics, the articulation and use of the concept of self-organization has been kept within the boundaries of complexity science and links to and from mainstream social science are scarce. These links can be difficult to establish, even for researchers working in social complexity with a background in social science, because of the theoretical and conceptual diversity and fragmentation in traditional social science. This article is meant to serve as a first step in the process of overcoming this lack of cross-fertilization between complexity and mainstream social science. A systematic review of the concept of self-organization and a critical discussion of similar notions in mainstream social science is presented, in an effort to help practitioners within subareas of complexity science to identify literature from traditional social science that could potentially inform their research.

The use of stories in research helps us better understand the world of teaching and learning since teachers and learners, like any other human being, are storytellers who engage in narrative acts to make sense of their and others’ knowledge and experiences. Even so, narrative research is a path not widely walked in the Colombian language teaching and learning context. This article is therefore an attempt to review some of the epistemological and methodological underpinnings underlying this approach to qualitative research so as to add to the local knowledge of our ELT community. It discusses the role of the researcher, the different orientations narrative studies can take, and the processes involved in narrative analysis. Some of the challenges narrative researchers face in their work, as well as the contributions of this method of inquiry to both the general education and TESOL fields are also considered.

Recent studies have highlighted the environmental benefits of the vernacular, focusing on the qualities of buildings; however, they do not sufficiently deal with the role of human agency in the production of the vernacular in practice. This study aims to demonstrate that by improving our understanding of the human and social aspects, it will be possible to define methods of supporting sustainable development. Understanding ‘the vernacular’ as a type of knowledge, four components are explored: transmission, use, motivations, and benefits. Based on the case of the Mexican Vault technique, the investigation offers insights into the various components of vernacular knowledge, suggesting the study of vernacular architecture from a perspective that elevates the relevance of the social and human dynamics in relation to the built object. It concludes that moving beyond environmental issues towards the building of tangible and intangible assets is a key challenge for vernacular architecture today.

Among the Tukano an indigenous peoples there is a ritual that reflects refined ecological management: ""The March of the Manikins"". By understanding this and similar cultural practices, we could attempt the re-definition of ""sustainability"" concept. A fundamental part of the process for the appropriation of a new meta-language that could set up new patterns for environmental management practices and policy delivering.

Abstract: The government take may be defined as an indicator to measure the participation of the State in the oil and gas projects developed under its jurisdiction or to compare fiscal regimes, but the truth is that this indicator is to be crucial in designing a competitive set of fiscal rules to attract foreign investment when needed. Usually a high or low government take will depend on the necessities of the particular country, but it is commonly admitted that countries with high government take have better success rates for exploration activity and vice versa. The aim of this paper is to analyse the government take of Colombia and provide some comparisons with the current exploratory activity. To do so, the indicator will be developed in detail to understand the elements comprised in it. Having mentioned what the main elements are, the next step will provide an overview of the current set of fiscal instruments used by Colombian government to take its share of the projects. The balance required to get the proper portion of the revenue without affecting the investor’s decision making process will be addressed. Subsequently some statistics on exploratory endeavours are to be exposed, because the final purpose of this paper is aimed at comparing if the fiscal set that compose the government take in Colombia is designed to successfully meet the investor’s expectations when oil and gas is eagerly pursued. Resumen: El “Government Take” puede definirse como un indicador para medir la participación del Estado en los proyectos de petróleo y gas desarrollados bajo su jurisdicción o para comparar regímenes fiscales, pero la verdad es que este indicador ha de ser crucial para diseñar un conjunto competitivo de medidas fiscales para atraer inversión extranjera cuando sea necesario. Usualmente una alta o baja participación del gobierno dependerá de las necesidades de un país en particular, pero comúnmente se admite que los países con alta participación del gobierno tienen mejores tasas de éxito para la actividad de exploración y viceversa. El objetivo de este ensayo es analizar el “Government Take” de Colombia y proporcionar algunas comparaciones con la actividad exploratoria actual. Para hacerlo, el indicador será desarrollado en detalle para comprender los elementos comprendidos en él. Habiendo mencionado cuáles son los principales elementos, el siguiente paso proporcionará una visión general del conjunto actual de instrumentos fiscales utilizados por el gobierno colombiano para tomar su parte de los proyectos. Se abordará el balance requerido para obtener la participación adecuada de los ingresos sin afectar el proceso de toma de decisiones del inversionista. Posteriormente, se expondrán algunas estadísticas sobre esfuerzos exploratorios, porque el objetivo final de este documento es comparar si el conjunto fiscal que compone el “Government Take” en Colombia está diseñado para cumplir con las expectativas del inversionista cuando se busca ansiosamente el petróleo y el gas.

The search for new technologies that guarantee the safety and quality of food has intensified, as has concern for consumer health, leading to the adoption of measures to reduce food-related risks. The purpose of the study was to evaluate the efficiency of active biodegradable films incorporated with bacteriophage for future application in packaging materials. Cellulose acetate films incorporated with solution of bacteriophages showed antimicrobial activity against Salmonella Typhimurium ATCC 14028 displayed the formation of inhibition zones in Muller-Hinton agar, and a growth curve, using the diffusion method in liquid medium. There was an increase in the lag phase and slower growth of microorganisms in the environment containing bacteriophages with the films, compared to control. The mechanical and physical properties of films, such as thickness, elongation and puncture resistance showed no significant effects. However, tensile resistance was different between control and treatments. The addition of bacteriophage altered the film surface, as observed by atomic force microscopy. There was a higher porosity of the films containing the bacteriophage solution compared to control. The acetate films may be incorporated with bacteriophages, since the physical and mechanical properties of the films were not changed drastically and there was an effect of the antimicrobial film.

Here; we present the genome sequence of the Escherichia coli bacteriophage UFV-AREG1. This phage was isolated from cowshed wastewater and showed specificity for enterohemorrhagic E. coli O157:H7 (ATCC 43895); E. coli 0111 (CDC O11ab) and E. coli (ATCC 23229).
