Las primeras damas como relaciones públicas: el caso de Michelle Obama

La falta de confiança en la política ha provocat una major presència de les relacions públiques en aquest terreny. El desenvolupament d’aquesta disciplina permet establir conexions amb els públics objectiu, despertant en ells sentiments de convicció, simpatia i afinitat. En moltes ocasions, aquest tipus de maniobres es dut a terme per l’esposa de presidents com el d’EE.UU.. La primera dama té una capacitat de representació i proximitat molt apropiada per integrar els seus públics i el mitjà social en un ambient favorable a l’administració que lidera el seu marit

New approaches for the control and eradication of schistosomiasis in Venezuela

Schistosomiasis in Americawith the exception of Brazil, behaves as a chronic mild disease with few clinical manifestations due to low parasite burden. These features restrict the clinical and parasitological diagnosis. The most commonly used stool examination method, Kato-Katz, becomes intensitive when the majority of individuals excrete less than 100 eggs/g of feces. In view that antigen-detecting techniques have not been able to reveal light infections, the antibody detecting assays remain as a very valuable diagnostic tool for epidemiological surveillance. The Venezuelan Schistosomiasis Research group (CECOICE) has designed a mass chemotherapy strategy based on sero-diagnosis. Since blood sampling is one of the important limitating factors for large seroepidemiological trials we developed a simple capillary technique that sucessfully overcomed most of the limitations of blood drawing. In this sense, ELISA seems to be the most adecuate test for epidemiological studies. Soluble egg Schistosoma mansoni antigen (SEA) has been largely used in Venezuela. The sensitivity ELISA-SEA in our hands is 90% moreover its specific reach 92% when populations from non-endemic areas but heavily infected with other intestinal parasites are analyzed. The Schistosomiasis Control Program is currently carrying out the surveillance of endemic areas using ELISA-SEA as the first screening method, followed by the Circumoval Precipitin test for validation assay. The results with these two serological techniques allowed us to defined the criteria of chemotherapy in populations of the endemic areas. On the search of better diagnostic technique, Alkaline Phosphatase Immunoenzyme Assay (APIA) is being evaluated in field surveys.

Spatial and temporal distribution of anopheline larvae in two malarious areas in Sucre State, Venezuela

The spatial and temporal distribution of anopheline larvae was studied in two coastal malarious areas of Sucre, State, Venezuela. Seven habitat types were sampled in the village of Guayana and eight species of Anopheles were collected. Anopheles aquasalis was the predominant species collected and was most abundant in the brackish marsh habitat (71 larvae per 100 samples). It was most abundant during the rainy season. At the second location, Santa F e, six habitat types were sampled and four anopheline species were collected. Habitats where An. aquasalis was most abundant were temporary freshwater ponds (34 larvae per 100 samples) and mangroves (10.5 larvae per 100 samples). At this location it was also most abundant in the rainy season. During the dry season it was collected in small numbers in river pools (1.3 larvae per 100 samples) along with large numbers of An. pseudopunctipennis (479 larvae per 100 samples). Larval control could be an important component of the malaria control program because major habitats could be defined and presence and abundance of larvae was limited to specific times of year.

Adult abundance, biting behavior and parity of Anopheles aquasalis, Curry 1932 in two malarious areas of Sucre State, Venezuela

The principal vector of malaria in eastern Venezuela, Anopheles aquasalis, is exophagic and exophilic. Control using indoor insecticide house sprays has failed to lower the number of malaria cases. Therefore, studies were initiated in two villages of the eastern coastal state of Sucre to better understand this vector's biology and develop a more integrated control program. An. aquasalis was found to have a crepuscular biting behavior with a major peak at dusk and a minor peak at dawn. Mosquitos were collected more outdoors than indoors. Forty-seven percent of the biting took place before people went to bed (22:30 hr) and 69% of the mosquitos biting during this time period bite outdoors. Outdoor biting could be the reason why indoor spraying alone did not lower malaria cases. Seasonal abundance was greater in the rainy season compared to the dry season. Seasonal parous rates were high (78.3%-100%) and similar indoors and outdoors and between dry and wet season in Santa F e. In Guayana, the seasonal parity was lower (34.6%-42.2%) than Santa F e with indoor parity slightly higher than outdoors. Malaria cases were higher in Santa F e, but adult mosquito density was much lower than in Guayana. This difference could have been due to higher parity in Santa F e compared to Guayana. The greater distance to the nearest breeding site and presence of alternative hosts in Guayana can not be discounted as factors which contributed to the difference in malaria transmission between locations. We concluded that knowledge on seasonal occurrence, biting activity, resting behavior and breeding site location can be used to design a new control strategy for this vector.

Individualismo y democracia: relaciones entre las estructuras de poder y el sujeto posmoderno

Aquest treball analitza la relació de les estructures del poder democràtic amb la posició existencial adoptada en massa pel subjecte postmodern. L’home d’avui s’ha llençat a una recerca inacabable de la seva pròpia identitat: creu que aquesta deu ser construïda sense atendre a cap factor extern. A més, està immers en una terrible soledat que el converteix en l’objecte perfecte per a una consolidació ideològica del sistema democràtic. Així, l’objectiu del present anàlisi és el d’intentar desvetllar el nexe entre una determinada concepció del poder i el fet de que l’home hagi perdut de vista les qüestions més rellevants de la seva pròpia existència, fins al punt de no saber qui és.

Las relaciones de las teorías de Jung y el trabajo de Grotowski con sus actores

La finalidad del trabajo es demostrar que los objetivos que Grotowski pretendió en su trabajo con los actores en su primera época, ligada al teatro laboratorium, pueden ser contemplados desde el mapa conceptual de la psicología profunda o analítica creada por C.G. Jung. Este acercamiento, permite reimaginar este “proceso de autopenetración” que el creador polaco buscaba con sus actores desde esta visión psicológica concreta. Cabe afirmar, por tanto, que este trabajo actoral iba más allá de la dimensión escénica y era un método “terapéutico” de desarrollo de la personalidad del individuo-actor en su camino de transformación para llegar a ser lo que Grotowski denominó “actor santo”.

La polémica de los libros de texto de historia como caso de estudio en las relaciones sino-japonesas

En el año 1982, la prensa japonesa publicó que el Ministerio de Educación nipón había suavizado en los libros de texto de historia las atrocidades cometidas durante la Guerra del Pacífico mediante el proceso de autorización de los libros realizado por el gobierno. Esta polémica y la publicación del Nuevo Libro de Historia en el año 2001, han sido dos de las controversias que con más fuerza se han debatido y han influenciado las relaciones bilaterales entre la República Popular China y Japón. El presente trabajo de investigación analiza los factores que contribuyeron al surgimiento del debate sobre la interpretación de la historia en Japón y a la posterior expansión internacional de la polémica de los libros de texto.

Diagnosis of malaria by acridine orange fluorescent microscopy in an endemic area of Venezuela

Fluorescent (acridine orange) microscopical examination of capillary centrifuged blood (quantitative buffy coat [QBC®] analysis) and Giemsa stained thick blood smears (GTS) were compared for diagnosis of malaria in blood specimens from adults living in malaria transmission areas of the States of Bolivar and Amazonas in southeastern and south Venezuela, respectively. Of a total of 198 GTS examined, 95 subjects (48%) showed parasitaemia. Among the 95 blood films with a positive GTS, 94 were judged positive by the QBC. However, positive QBC tubes were found in 29 out of 103 blood specimens with a negative GTS. Thus, relative to a GTS standard, the sensitivity and specificity of the QBC-test was 99.2% and 72%, respectively. Young trophozoites of Plasmodium vivax and P. falciparum could not be distinguished with certainty. It is confirmed that the QBC offers many advantages compared with the standard diagnosis of malaria parasites, specifically in the speed of staining and ease of interpretation. However, in places where P. falciparum and P. vivax occur, species and stage differentiation should be confirmed with the GTS.

HIV type 1 drug resistance among naive patients from Venezuela.

In this study, we characterize proviral DNA of 20 HIV-1 asymptomatic antiretroviral-naive patients from Venezuela in env, gag, and pol genes regions. Results from both env/gag HMA subtyping and phylogenetic analysis of pol partial sequences led to the description of clade B in all cases. Nevertheless, the high prevalence of polymorphisms was particularly evident among the protease sequences. A 10% prevalence of major resistance mutations to RTIs was found. Our data also suggested that the protease polymorphisms I62T and V77T could be considered as molecular markers of the subtype B local epidemic. In addition, we show how proviral DNA can be used as a reliable tool to follow trends of resistance mutation transmission.

Comunicación en las ONG: aplicación a las relaciones públicas

La clau en la comunicació com eina de Relacions Públiques en una ONG està en conèixer els teus públics i saber adaptar-te al seu entorn. Al escoltar-los sabràs com dirigir-te a ells i quan els demanis la seva col·laboració hauràs de tenir molt presents les seves circumstancies per entendre’ls i poder oferir-los allò que més els beneficia. Les Relacions Públiques ens permetran donar a conèixer les activitats de la organització i obrir noves possibilitats de notorietat, captació de fons i augmentar donacions, però el secret residirà en realitzar la seva labor correctament ja que, com es diu en aquesta professió hem de; fer-ho bé i fer-ho saber.
