Burden, coping, physical symptoms and psychological morbidity in caregivers of functionally dependent family members

Objectives: this study assessed burden, coping, physical symptoms and psychological morbidity in caregivers of functionally dependent family members. Methods: fifty family caregivers completed self-reported measures of burden, physical symptoms, psychological morbidity and coping strategies. Results: there was a significant negative correlation between coping strategies and the different clinical variables, as well as a significant positive correlation between coping strategies and duration of care. It appears that the stronger bond between caregiver and family member leads to a poorer use of adaptive coping strategies. It also appears that the deterioration of the relationship between them and the lower perceived self-efficacy are more prominente in caregivers of family members with cognitive impairment, indicating that caregivers with family members without cognitive impairment face fewer difficulties. Conclusion: these results emphasize the need for interventions to include coping strategies, since they are important in reducing caregivers’ burden, psychological morbidity and physical symptoms

Tools to Support SMEs to Migrate to the Cloud: Opportunities and Challenges

The first author of this paper thanks for the Scholarship (T.O.B)-No BOL0731/2016 provided by the Research Foundation State of Bahia (FAPESB).The cloud computing paradigm represents a shift in the way companies deal with customizable and resourceful platforms to deploy software. It has been receiving increasing attention, partly due to its claimed financial and functional benefits. Cloud computing providers provide organizations with access to computing services without the need for those organizations to own the providing infrastructure. However, migration of legacy information systems to the cloud is not simple. This field is very dynamic and related technologies are rapidly evolving. For instance, Small and Medium Enterprises (SMEs) may not necessarily be well prepared to deal with issues such as multi-tenancy, elasticity, interoperability, and cloud services. With such issues in view, we searched for different types of tools referenced in the literature to support migration to the cloud and discussed related challenges and advantages of their use by SMEs.publishe

Marine microalgae attack and feed on metazoans

Free-living microalgae from the dinoflagellate genus Karlodinium are known to form massive blooms in eutrophic coastal waters worldwide and are often associated with fish kills. Natural bloom populations, recently shown to consist of the two mixotrophic and toxic species Karlodinium armiger and Karlodinium veneficum have caused fast paralysis and mortality of finfish and copepods in the laboratory, and have been associated with reduced metazooplankton biomass in-situ. Here we show that a strain of K. armiger (K-0688) immobilises the common marine copepod Acartia tonsa in a density-dependent manner and collectively ingests the grazer to promote its own growth rate. In contrast, four strains of K. veneficum did not attack or affect the motility and survival of the copepods. Copepod immobilisation by the K. armiger strain was fast (within 15 min) and caused by attacks of swarming cells, likely through the transfer and action of a highly potent but uncharacterised neurotoxin. The copepods grazed and reproduced on a diet of K. armiger at densities below 1000, cells ml(−1), but above 3500 cells ml(−1) the mixotrophic dinoflagellates immobilised, fed on and killed the copepods. Switching the trophic role of the microalgae from prey to predator of copepods couples population growth to reduced grazing pressure, promoting the persistence of blooms at high densities. K. armiger also fed on three other metazoan organisms offered, suggesting that active predation by mixotrophic dinoflagellates may be directly involved in causing mortalities at several trophic levels in the marine food web

Late Pleistocene leopards as a bone accumulator: taphonomic results from S’Espasa cave and other Iberian key sites

The Pleistocene faunal accumulations documented in caves have commonly been attributed to the activity of humans or carnivores. According to the palaeontological and archaeological literature, cave hyena (Crocuta spelaea) was the main known bone accumulator in karstic environments. However, in recent times, the role of leopards as bone accumulators has been revealed, and recent research has identified this behaviour in the Iberian Pleistocene. Moreover, there are other caves where leopard could have been claimed as an accumulator such as S’Espasa. In this work we present its taphonomic study. This cave was compared with the actualistic studies of leopards. Besides, the site of S’Espasa was compared with the other leopard dens in the Iberian Peninsula. These sites present faunal assemblages composed mainly by leopard (Panthera pardus) and Iberian wild goat (Capra pyrenaica), the bones of this ungulate present a similar pattern of bone modification by carnivores, skeletal survival rate, and bone breakage. These features indicate that goats could have been accumulated by leopards. With the data from this work and the previous ones, we try to establish a pattern that will help in the future to identify other accumulations created by this big cat.Fil: Sauqué Latas, Víctor.
