Transformaciones discursivas en el proceso de securitización del narcotráfico. Un análisis de los actos discursivos oficiales de Colombia y Estados Unidos en la Guerra contra las drogas 1986 - 1990

El tema de las drogas suscita un debate entre quienes defienden la prohibición y la represión, y aquellos que defienden alternativas como la legalización y/o regulación y otras más moderadas como la descriminalización y la despenalización. Aunque ambas posturas muestran datos empíricos que las soportan, desde el ámbito discursivo la visión represiva se ha posicionado como la más aceptada en el continente americano, más específicamente, en Latinoamérica. El presente trabajo, hace un estudio de caso del proceso de securitización del narcotráfico entre los presidentes de Estados Unidos y Colombia durante el período 1986-1990. A lo largo del texto, se analizan discursos oficiales de los presidentes de ambos Estados, resaltando las estrategias retóricas y sus transformaciones que legitimaron acciones represivas de tipo político-militar contra las drogas. Al final se apunta a reivindicar el discurso como un instrumento para reproducir creencias sobre fenómenos, en este caso, la creencia de que las drogas son una amenaza existencial a la seguridad política y militar para los Estados.

Participación política a través de acciones constitucionales. Estudio de caso: matrimonio para personas del mismo sexo en Colombia

El interés de esta investigación se centra en analizar el rol protagónico que han adquirido las acciones constitucionales en la participación política de la comunidad LGTBI, encaminada a la aprobación del matrimonio igualitario en Colombia, a partir de la promulgación de la Constitución Política de 1991. Para este propósito, el estudio presenta un diagnóstico sobre las falencias y limitaciones que ha presentado la representación política y de los mecanismos de participación ciudadana para solventar las reivindicaciones de las parejas del mismo sexo. En consecuencia, la investigación evidencia de qué manera la sub-representación de los intereses de esta comunidad en el Congreso de la República y la sub-utilización de los mecanismos de participación política causadas por las deficiencias en su diseño e implementación, impulsaron a la población LGTBI y los defensores de sus derechos a canalizar su participación política a través de la presentación de acciones constitucionales.

Cronologia dels programes femenins a la ràdio catalana d’abans de la Guerra Civil

El propòsit d’aquest article és endreçar la cronologia dels programes femenins que les estacions de ràdio pioneres emetien a Catalunya abans de la Guerra Civil i conèixer-ne els trets diferenciadors que tenien. Tal com ja he posat de manifest en les conclusions de la meva tesi doctoral, i en alguns dels articles que se n’han derivat, els programes femenins que les emissores catalanes varen dur a terme abans de 1939 van ser els primers espais de la radiodifusió espanyola que varen tenir el que ara coneixem com a format. Aquesta manera d’entendre un programa de ràdio, que ja va tenir una locutora a finals dels anys vint, ha permès que ara investiguem, per ordenar-los cronològicament, aquests espais tan vells i tan preuats de la ràdio pionera, i que a més a més puguem revelar quines característiques comunes tenien tots aquests espais femenins, a partir de saber els detalls de tots els que varen coincidir, en el temps, a les ones de Barcelona

CHC students online : responses to course organisation

Previous research by the authors has shown that Confucian Heritage Students participating in online problem solving discussions show a high degree of message postings that are related to the organization of the course of study, rather than to its contents and intellectual challenges. The authors argue that this is consistent with the more broadly based research outcomes relating to the achieving strategy that is quite typically exhibited among CHC students. This interview based study explores the perceptions of CHC students as they engage with collaborative learning online, and shows that the concerns relate to matters to do with assessment, with the reliability and timeliness of group member inputs, and the possibilities of plagiarism.

How can managers reduce employee intention to quit?

This paper reports on an investigation of the variables that may be predictive of intentions to leave a job, and tests a model that includes mediating variables. A total of 173 retail salespeople completed questionnaires measuring commitment to the organization for which they worked, job satisfaction, stress, supervisor support, locus of control, self-esteem, the perceived stressors in the job and their intention to quit. Path analysis was used to test the relationships hypothesized in the model. The majority of hypotheses were supported, with the variables included accounting for 52 per cent of the variance in intention to quit. Emotional support from supervisors and self-esteem mediated the impact of stressors on stress reactions, job satisfaction, commitment to the organization and intention to quit. It is suggested that to ameliorate intention to quit and in turn reduce turnover, managers need to actively monitor workloads, and the relationships between supervisors and subordinates in order to reduce and manage stress. Managers also need to monitor both the extrinsic and intrinsic sources of job satisfaction available to employees. These activities could assist in maintaining and increasing job satisfaction and commitment to the organization.

Movement patterns of southern bell frogs (Litoria raniformis) in response to flooding

Within the semiarid regions of New South Wales, Australia, the endangered southern bell frog (Litoria raniformis) occupies a landscape that is characterised by unpredictable rainfall and periodic flooding. Limited knowledge of the movement and habitat-occupancy patterns of this species in response to flood events has hampered conservation efforts. We used radio-tracking to assess changes in movement patterns and habitat occupancy of L. raniformis (n = 40) over three different periods (November, January and April/May) that coincided with the flooding, full capacity and subsequent drying of waterbodies within an irrigation landscape. We assessed (1) the use of permanent and ephemeral habitats in response to flooding and drying and (2) distances moved, turning angles and dispersion of frogs during wetland flooding, full capacity and drying. Individuals remained in permanent waterbodies in November but had abandoned these areas in favour of flooded ephemeral waterbodies by January. As the ephemeral waterbodies dried, radio-tracked individuals moved back into permanent waterbodies. The movement patterns of radio-tracked individuals were significantly different in the three radio-tracking periods, but did not differ significantly between sexes. Individuals moved significantly greater distances over 24 h, in straighter lines and movements were more dispersed while they occupied ephemeral waterbodies during January than when they occupied permanent waterbodies during November and April/May. Local weather conditions did not influence movement patterns when all three tracking periods were modelled together using a single linear stepwise regression. The dynamic distribution of habitat patches over space and time, combined with changing patterns of resource utilisation and movement of L. raniformis, highlights the importance of incorporating both permanent and ephemeral habitat patches into conservation plans. Reductions in flood frequency and extent of ephemeral wetlands due to modified flooding regimes have the capacity to limit dispersal of this species, even when permanent waterbodies remain unchanged.

ABC online : a vortal for new opportunities?

This article undertakes an analysis of the ABCs website, ABC Online -- www. abc.net.au -- to explore how the public broadcaster uses the Internet to offer new services. While recognising that the ABC aims to enhance its traditional radio and television services using the Internet, the article establishes the extent to which ABC Online also provides innovative, original, and interactive new services, including those with no connection to traditional radio and television programs, as is often demanded by audiences. This article examines the capacity for ABC Online to develop a unique and distinctive role via the Internet through the potential to offer novel and interactive content and services.

The role of media networks in compensating political biases: evidence from radio networks in Brazil

A central question in political economy is how to incentivize elected socials to allocate resources to those that need them the most. Research has shown that, while electoral incentives lead central governments to transfer fewer funds to non-aligned constituencies, media presence is instrumental in promoting a better allocation of resources. This study evaluates how these two phenomena interact by analyzing the role of media in compensating political biases. In particular, we analyze how media presence, connectivity and ownership affect the distribution of federal drought relief transfers to Brazilian municipalities. We find that municipalities that are not aligned with the federal government have a lower probability of receiving funds conditional on experiencing low precipitation. However, we show that the presence of radio stations compensates for this bias. This effect is driven by municipalities that have radio stations connected to a regional network rather than by the presence of local radio stations. In addition, the effect of network-connected radio stations increases with their network coverage. These findings suggests that the connection of a radio station to a network is important because it increases the salience of disasters, making it harder for the federal government to ignore non-allies. We show that our findings are not explained by the ownership and manipulation of media by politicians.

The Methodological Influence of Peirce's Pragmatism on Knowledge Organization

Information and knowledge organization in Brazil has been historically influenced by theoretical linguistics. However, some aspects related to language theory and its interface with philosophy need to be further investigated, particularly the semiotic interpretation of information and knowledge organization processes. In order to advance a dialogue with the philosophy and semiotics of Charles Peirce (1839-1914), a theoretical and bibliographical study was carried out so as to understand and evaluate the contributions of the Peircean thought to information organization. It was found that several aspects of Peirce's work, viewed as a whole and not just semiotic concepts, suggest fundamental points to explain issues in information and knowledge organization. Basing on the analysis of Thellefsen's studies, this research presents some arguments aimed at reframing Peirce's pragmatism, which should no longer be mistakenly considered as a doctrine of practical results, but as a useful methodological approach for professionals dealing with knowledge organization in the field of Information Science.

Theoretical Approximations Between Brazilian and Spanish Authors' Production in the Field of Knowledge Organization in the Production of Journals on Information Science in Brazil

This work identifies and analyzes literature about knowledge organization (KO), expressed in scientific journals communication of information science (IS). It performs an exploratory study on the Base de Dados Referencial de Artigos de Periodicos em Ciência da Informacio (BRAPCI, Reference Database of Journal Articles on Information Science) between the years 2000 and 2010. The descriptors relating to "knowledge organization" are used in order to recover and analyze the corresponding articles and to identify descriptors and concepts which integrate the semantic universe related to KO. Through the analysis of content, based on metrical studies, this article gathers and interprets data relating to documents and authors. Through this, it demonstrates the development of this field and its research fronts according to the observed characteristics, as well as noting the transformation indicative in the production of knowledge. The work describes the influences of the Spanish researchers on Brazilian literature in the fields of knowledge and information organization. As a result, it presents the most cited and productive authors, the theoretical currents which support them, and the most significant relationships of the Spanish-Brazilian authors network. Based on the constant key-words analysis in the cited articles, the co-existence of the French conception current and the incipient Spanish influence in Brazil is observed. Through this, it contributes to the comprehension of the thematic range relating to KO, stimulating both criticism and self-criticism, debate and knowledge creation, based on studies that have been developed and institutionalized in academic contexts in Spain and Brazil.
