The Context Influence in Volunteers Motivations

Volunteers working in different areas or different NPO (Non-profit Organisations) are significantly different according to several variables, namely in terms of motivation, satisfaction and permanence. Thus, the main goal of this research is to understand volunteers’ motivations and the influence of the context on it. Additionally, demographic variables might have an important impact on volunteers’ activities, be an important predictor of volunteering and, at the same time, influence their time commitment. In this paper we present data from twelve different NPO - 10 hospitals and 2 food banks. The model of data collection was a survey conducted by self-administered questionnaire. The results showed significant differences between the volunteers’ belonging to the two organisations and their motivations, confirming that volunteer’ motivations differ according the type/nature of organisation; this is particularly important because the field in which one works is influenced by a self-evident affinity with shared ideologies, religious convictions, and collective identities. These results present important outcomes that should be reflected in the way organisations act. Keywords: Volunteering; Occasional and permanent volunteers; Motivations; Non-profit organisations.

Identity and belonging in the novels of Dorn Rabinovici

This essay analyses how the different types of memory may influence the process of identity formation. It shall be argued that not only memories formed upon the subject’s experiences play a key role in this process; intermediated, received narratives from the past, memories transmitted either symbolically or by elder members of the group, or, what has been meanwhile termed as “postmemory”, also play an important part in the development of an individual’s identitary map. This theoretical framework will be illustrated with the novelistic work of Austrian Israeli-born historian, writer and political activist Doron Rabinovici (*1961). As a representative of the so-called “second generation” of Holocaust writers, a generation of individuals who did not experience the nazi genocide violence, but who had to form their identities under the shadow of such a brutal past, Rabinovici addresses essential topics such as the intergenerational transmission of memory and guilt within survivor families, identity formation of second generation individuals (Jews and non-Jews) and the question of simultaneously belonging to different social, historical and linguistic contexts.

Valor de los metodos directos e indirectos de diagnóstico en las micosis sitémicas asociadas al SIDA

Durante 5 años se estudiaron 117 pacientes con micosis sistémicas asociadas al SIDA: 74 criptococosis, 39 histoplasmosis y 4 con ambas enfermedades. Para el diagnóstico analizamos los siguientes materiales: escarificaciones de lesiones cutáneas o mucosas, aspirados de médula ósea, secreciones bronquiales, biopsias de diversos órganos, líquido cefalorraquídeo, hemocultivos y sueros para determinaciones serológicas. Fueron estudiadas en total 203 muestras de pacientes con histoplasmosis, el 46.3% de las mismas acusó la presencia de H. capsulatum. Las escarificaciones cutáneas exhibieron la mayor sensibilidad (94.7%), seguidas por las biopsias (80%) y los mielocultivos (42.1%). La demostración de anticuerpos circulantes por medio de 3 pruebas serológicas y con de 2 antígenos específicos dio resultados positivos en el 45.4% de los pacientes. Se estudiaron en total 413 especímenes de pacientes con criptococosis, la confirmación diagnóstica fue posible en el 69% de las muestras. El mayor rendimiento se obtuvo con el LCR (89.5%), le seguieron en sensibilidad los hemocultivos (61.2%), las escarificaciones cutáneas (42.9%) y los urocultivos (41.7%). La búsqueda de antígeno en los fluidos orgánicos fue positiva en casi todos los casos. La revisión que presentamos permitirá una búsqueda más racional y rápida de los métodos de diagnóstico en las micosis asociadas al SIDA.

Estimation of the Crustal Bulk Properties Beneath Mainland Portugal from P-Wave Teleseismic Receiver Functions

In this work, we present results from teleseismic P-wave receiver functions (PRFs) obtained in Portugal, Western Iberia. A dense seismic station deployment conducted between 2010 and 2012, in the scope of the WILAS project and covering the entire country, allowed the most spatially extensive probing on the bulk crustal seismic properties of Portugal up to date. The application of the H-κ stacking algorithm to the PRFs enabled us to estimate the crustal thickness (H) and the average crustal ratio of the P- and S-waves velocities V p/V s (κ) for the region. Observations of Moho conversions indicate that this interface is relatively smooth with the crustal thickness ranging between 24 and 34 km, with an average of 30 km. The highest V p/V s values are found on the Mesozoic-Cenozoic crust beneath the western and southern coastal domain of Portugal, whereas the lowest values correspond to Palaeozoic crust underlying the remaining part of the subject area. An average V p/V s is found to be 1.72, ranging 1.63-1.86 across the study area, indicating a predominantly felsic composition. Overall, we systematically observe a decrease of V p/V s with increasing crustal thickness. Taken as a whole, our results indicate a clear distinction between the geological zones of the Variscan Iberian Massif in Portugal, the overall shape of the anomalies conditioned by the shape of the Ibero-Armorican Arc, and associated Late Paleozoic suture zones, and the Meso-Cenozoic basin associated with Atlantic rifting stages. Thickened crust (30-34 km) across the studied region may be inherited from continental collision during the Paleozoic Variscan orogeny. An anomalous crustal thinning to around 28 km is observed beneath the central part of the Central Iberian Zone and the eastern part of South Portuguese Zone.

Detection of Cryptococcus neoformans capsular polysaccharide antigen in asymptomatic HIV-infected patients

Serum samples from 242 HIV-positive persons were studied for the detection of capsular polysaccha-ride antigen of Cryptococcus neoformans; 193 of these patients presented less than 300 CD4+ cells/µl of blood and 49 patients had more than 300 CD4+ cells/µl. None of them had symptoms or signs characteristic of cryptococcosis. The capsular antigen of C. neofarmans was detected by latex agglutination technique with pronase pre-treatment (IMMY, Crypto-Latex Antigen Detection System, Immunomycologics Inc., OK, USA); in 61% of the samples, ELISA technique was also used (Premier, Cryptococcal Antigen, Meridian Diagnostic Inc., Cincinatti, Oh, USA). The comparative study of both methods showed that the results obtained were similar in 96.9% of the cases. The capsular antigen was detected in 13 out of 193 (6.7%) patients with less than 300 CD4+ cells/µl. Cryptococcosis was confirmed mycologically in 3 of these 13 cases (23%) by the isolation of C. neoformans in CSF or blood cultures. Three patients, who had presented negative results of both tests for capsular antigen, suffered disseminated cryptococcosis 4 to 8 months later. The predictive diagnostic value of capsular antigen detection of C. neoformans seems tobe low and we believe that it should not be done routinely in asymptomatic HIV-positive persons.

The most Portuguese village in Portugal: tradition in the age of its technical reproducibility

Ethnographic film is often associated with many European countries’ past as colonial powers and the way these countries used film to depict African, American and Asian territories and populations they once ruled. However, ethnographic film also has a European tradition of its own, closely interlaced with the history of ethnography and anthropology as autonomous sciences and with the desire of scholars to represent local, regional and national cultural identities. This paper presents a Portuguese attempt of this sort dating from 1938, when the authoritarian regime organized a national contest to determine which would be Portugal’s most “authentic” village – something other European countries also did. As part of this metonymic contribution to the construction of Portugal’s national identity as an agrarian utopia, a short documentary was shot, sponsored by the same official propaganda office that had organized the contest. In this film, the viewer’s gaze is made to coincide with the one of the national jury visiting the final selection of 12 villages and to whose benefit local scholars had organized all sorts of colourful peasant traditions hoping to cause the strongest impression. The film makes a strong case for the importance of ethnographic film as a relevant instance not only of the iteration of existing European national cultures, but also of the construction of so many of Europe’s national identities and traditions. Suffice to say that even today the village of “Monsanto”, which won the 1938 contest, is still referred to as “Portugal’s most Portuguese village”.

Environmental straits of Cryptococcus neoformans variety grubii in the city of Santos, SP, Brazil

This study involved a total of 116 samples, 79 taken from pigeon droppings and 37 of atmospheric air taken close to accumulations of excrement. Cryptococcus neoformans var. grubii was isolated from 11 (13.9%) of these samples. Other species of Cryptococcus were also isolated from these samples, such as C. albidus (12.6%) and C. laurentii (8.9%). C. neoformans was not isolated from the air samples, though C. albidus (5.4%) was. All the strains of C. neoformans were found to belong to the A serotype (C. neoformans var. grubii). In regard to the studies with the antifungal agents 5-fluorocytosine, fluconazole, itraconazole, amphotericin B and voriconazole, by means of the microdilution method (EUCAST), we point out that one sample demonstrated resistance to fluconazole, this being especially significant because this is an environmental strain.

Natural infection of phlebotomines (Diptera: Psychodidae) in a visceral-leishmaniasis focus in Mato Grosso do Sul, Brazil

The main purpose of this study was to investigate natural infection by Leishmania in phlebotomine females in a visceral-leishmaniasis focus in Antonio João county in Mato Grosso do Sul State, Brazil. Between June and October 2003, the digestive tracts of 81 females captured in Aldeia Campestre, Aldeia Marangatu and Povoado Campestre were dissected. The females were separated by species, location, area and date of capture into 13 groups and kept in ethanol 70%. To identify the Leishmania species using the PCR technique, amplifications of the ribosomal-DNA (rDNA) and mini-exon genes were analyzed. Of the 81 specimens, 77 (95%) were Lutzomyia longipalpis, making this the most common species; only one specimen of each of the species Brumptomyia avellari, Evandromyia cortelezzii, Evandromyia lenti and Nyssomyia whitmani was found. Trypanosomatids were identified in eight of the nine groups of Lutzomyia longipalpis (10.39%) one group from Aldeia Campestre, one from Aldeia Marangatu and six from Povoado Campestre; of the eight groups, one from Aldeia Marangatu and another, with promastigotes forms also confirmed by dissection (1.23%) from Povoado Campestre, were identified by PCR as Leishmania chagasi (2.6%). The other groups gave negative results. These findings indicate that there is a high risk of leishmaniasis transmission in this area.

Disseminated nocardiosis with psoas abscess in a patient with AIDS: first reported case

Psoas muscle abscess is an uncommon infection that have been diagnosed increasingly in the last years. We present a case of a patient with advanced human immunodeficiency virus infection who developed a disseminated infection due to Nocardia asteroides sensu stricto type VI with psoas abscess. To our knowledge no other cases of Nocardia psoas abscess in the setting of HIV infection have been reported in the literature.
