The Impact of Career Experiences on Generativity and Postretirement Choices for Intelligence Community Baby Boomers
This study focused on baby boomers and explored how a career with a mission-focus in the Intelligence Community influenced boomer generativity and subsequent choices after retirement. Baby boomers make-up the majority of the population that is retirement eligible today and have the benefit of a longer life expectancy commensurate with improvements in health care over the past century. Current retirement literature covers a range of options that redefine what retirement means today. This study employed a two-phase mixed method approach to investigate the characteristics and impacts of a mission-focused career, and to understand how such experiences impact postretirement opportunities and choices. During Phase 1 a survey was administered to 280 retired Intelligence Community members and included an established Social Generativity Scale (SGS) derived by Morselli and Passini (2015). Phase 1 results showed that most respondent’s personal work experience included a range of selfless or service related factors within their work environment, and also identified a high level of social generativity. A series of regression analyses identified the ability to make a difference and a shared sense of purpose as the most significant aspects of an Intelligence Community experience. Additionally participants’ postretirement activities were influenced by their Intelligence Community “mission-focused” work experiences. Their work in the Intelligence Community and sense of generativity positively influenced their choice of activities after retirement. In Phase 2 of the study, focus groups with a subset of survey respondents reflected on the results from Phase 1 as it pertained to their personal lives and choices. Stories documented that a strong sense of mission and service persisted in postretirement activities, both formal work roles as well as a strong sense of volunteerism. Despite study limitations, positive implications for future studies looking across different population segments provide an avenue to further explore these relationships between selfless work experiences as a component of postretirement directions.

Memorias del contacto. Relaciones indios-blancos en Misiones 1920-1960. 16H290
En el presente trabajo de investigación nos proponemos incursionar en un tema poco
analizado en la historia de Misiones: el contexto y la forma en que se produjeron los primeros
contactos entre inmigrantes de origen europeo e indígenas mbya en la provincia en el periodo
correspondiente a 1920-1960. Nos interesa también conocer cómo eran las relaciones entre los
mbya y la población de origen paraguayo y criolla en general, quienes trabajaban como mano
de obra en yerbales y obrajes, constituyendo, por lo tanto, los primeros en tomar contacto con
los indígenas. Indagaremos acerca de las características de esas primeras relaciones
interétnicas, si existían intercambios de objetos y alimentos, si hubo violencia para expulsarlos
de sus territorios a medida que se formaban las colonias destinadas a los inmigrantes, los
conflictos derivados de la ocupación de las tierras. Si hubo intentos de contratarlos como
peones para desmontar la selva y desde cuándo comienzan los mbya a trabajar para los
colonos.
Como contraparte, nos interesa conocer la visión indígena de aquellos primeros contactos,
viva aún en la memoria de los ancianos. Cómo fueron los primeros contactos con los blancos
y en qué contextos ocurrieron.
También realizaremos la búsqueda y recopilación de material fotográfico inédito producido en
la provincia durante las primeras décadas del siglo XX a los fines de análisis documental
RN Perception of Mentoring in a Hospital Environment
Background: Baptist Health South Florida currently has a formal mentoring program. Although there has been good attendance with the mentoring classes, the participants fail to commit to formal mentoring. Consequently, system-wide, there are few formally trained mentors.
Purpose:This study was to understand the nurse mentoring culture within a hospital environment as well as identify and analyze the barriers to nurse mentoring using a focus group methodology.
Methods: This qualitative study explored nurse perceptions of a mentoring culture within a hospital environment. Open-ended, conversational-style interviewing techniques with a semi-structured interview guide followed by probes to elicit more specific information were used to gain a full description of each nurse’s perceptions.
Results: A structural model of mentoring as perceived by hospital nurses was developed from the data. Five overarching themes with corresponding subthemes emerged from the focus group data. (1) Mentoring culture: various mentoring models, informal vs formal, leader focused, and evolving. (2) Benefits: connections, development, retention, stability, patient safety, and making a difference. (3) Barriers: time, patients/patience, competition, knowledge deficit regarding mentor verses preceptor roles, lack of incentives, receptiveness, and voluntold. (4) Experience with mentoring: going above and beyond, lifetime relationships, personal/professional growth, feeling cared for. (5) Paradigm shift: match generational and cultural differences, resources, face to face, and voluntary.
Conclusions: The study results have identified mentoring as an integral aspect of personal and professional growth within the hospital environment. The rewards of mentoring or being mentored translated into increased retention, and nurse satisfaction. However there are identified barriers that need to be overcome. The most notable finding was the distinct knowledge deficit regarding the role and responsibilities of a mentor verses a preceptor in the hospital environment
Vector Competence of Argentine Mosquitoes (Diptera: Culicidae) for West Nile virus (Flaviviridae: Flavivirus)
We examined the ability of Culex pipiens L. complex mosquitoes from Argentina to vector West Nile virus (WNV) to assess their role in the transmission of WNV in South America. Several egg rafts of Culex spp. were collected from different breeding sites in the suburbs of the city of La Plata, Argentina, and a subset of each progeny was scored with morphological and genetic species indicators. Surprisingly, we did not find Cx. pipiens form pipiens, but found evidence of genetic hybrids of Culex quinquefasciatus and Cx. pipiens f. molestus. We then used morphological traits to create two colonies predominantly composed of one of these two taxa, although some hybrids are likely to have been included in both. These colonies were used in vector competence studies using NY99 and WN02 genotype strains of WNV obtained in New York State. As controls, we also tested colonies of U.S. Cx. quinquefasciatus and Cx. pipiens f. molestus. Additional Culex larvae from three drainage ditches near the cities of La Plata and Berisso, Argentina, were identified by morphological and high-resolution molecular markers (microsatellites) as Cx.
quinquefasciatus Say, Cx. pipiens form molestus, and hybrids. Results indicate that Argentinian Culex are competent but only moderately efficient vectors of WNV and are less susceptible to this virus than comparable U.S. mosquito strains. Studies of vertical transmission of NY99 virus by Cx. pipiens f. molestus hybrids from Argentina yielded a minimal filial infection rate of 1.19 from females feeding during their second and later bloodmeals.Centro de Estudios Parasitológicos y de Vectore
Factors Related to Aedes aegypti (Diptera: Culicidae) Populations and Temperature Determine Differences on Life-History Traits With Regional Implications in Disease Transmission
Aedes aegypti (L.) (Diptera: Culicidae) is a vector of many medically significant viruses in the Americas, including dengue virus, chikungunya virus, and Zika virus. Traits such as longevity, fecundity, and feeding behavior contribute to the ability of Ae. aegypti to serve as a vector of these pathogens. Both local environmental factors and population genetics could contribute to variability in these traits. We performed a comparative study of Ae. aegypti populations from four geographically and environmentally distinct collection sites in Argentina in which the cohorts from each population were held at temperature values simulating a daily cycle, with an average of 25°C in order to identify the influence of population on life-history traits. In addition, we performed the study of the same populations held at a daily temperature cycle similar to that of the surveyed areas. According to the results, Aguaray is the most outstanding population, showing features that are important to achieve high fitness. Whereas La Plata gathers features consistent with low fitness. Iguazu was outstanding in blood-feeding rate while Posadas's population showed intermediate values. Our results also demonstrate that climate change could differentially affect unique populations, and that these differences have implications for the capacity for Ae. aegypti to act as vectors for medically important arboviruses.Fil: Muttis, Evangelina.

Differential Effects of Temperature and Mosquito Genetics Determine Transmissibility of Arboviruses by <i>Aedes aegypti</i> in Argentina
Aedes aegypti (L.) (Diptera: Culicidae) have a global distribution and are the primary vector of a number of mosquito-borne viruses responsible for epidemics throughout the Americas. As in much of South America, the threat from pathogens including dengue virus (DENV; Flaviviridae, Flavivirus) and chikungunya virus (CHIKV; Togaviridae, Alphavirus) has increased in Argentina in recent years. The complexity of transmission cycles makes predicting the occurrence and intensity of arbovirus outbreaks difficult. To gain a better understanding of the risk of DENV and CHIKV in Argentina and the factors influencing this risk, we evaluated the role of population and temperature in the vector competence and vectorial capacity (VC) of Ae. aegypti from geographically and ecologically distinct locations. Our results demonstrate that intrinsic and extrinsic factors including mosquito population, viral species, and temperature significantly influence both vector competence and overall VC of Ae. aegypti in Argentina, yet also that the magnitude of these influences is highly variable. Specifically, results suggest that CHIKV competence is more dependent on mosquito genetics than is DENV competence, whereas temperature has a greater effect on DENV transmission. In addition, although there is an overall positive correlation between temperature and competence for both viruses, there are exceptions to this for individual virus?population combinations. Together, these data establish large variability in VC for these pathogens among distinct Ae. aegypti populations in Argentina and demonstrate that accurate assessment of arbovirus risk will require nuanced models that fully consider the complexity of interactions between virus, temperature, mosquito genetics, and hosts.Centro de Estudios Parasitológicos y de Vectore

Biological characterization of Aedes albopictus (Diptera: Culicidae) in Argentina: Implications for arbovirus transmission
Aedes albopictus (Diptera: Culicidae) is an invasive mosquito, native to Asia, that has expanded its range worldwide. It is considered to be a public health threat as it is a competent vector of viruses of medical importance, including dengue, chikungunya, and Zika. Despite its medical importance there is almost no information on biologically important traits of Ae. albopictus in Argentina. We studied life cycle traits, demographic parameters and analyzed the competence of this mosquito as a virus vector. In addition, we determined the prevalence of Wolbachia strains in Ae. albopictus as a first approach to investigate the potential role of this bacteria in modulating vector competence for arboviruses. We observed low hatch rates of eggs, which led to a negative growth rate. We found that Ae. albopictus individuals were infected with Wolbachia in the F1 but while standard superinfection with wAlbA and wAlbB types was found in 66.7% of the females, 16.7% of the females and 62.5% of the males were single-infected with the wAlbB strain. Finally, despite high levels of infection and dissemination, particularly for chikungunya virus, Ae. albopictus from subtropical Argentina were found to be relatively inefficient vectors for transmission of both chikungunya and dengue viruses.Centro de Estudios Parasitológicos y de Vectore
