Conditional dependence diagnostic in the latent class model: A simulation study

  • Autores: de Oliveira MR, Gonçalves L, Subtil A
  • Journal: Statistics & Probability Letters
  • Link: https://apps.webofknowledge.com/full_record.do?product=UA&search_mode=GeneralSearch&qid=4&SID=T2VvZFAKYvQv3Eo9tzK&page=1&doc=7

The classical latent class model assumes the hypothesis of conditional independence. We explore tools commonly used to validate this hypothesis (correlation residual plot, log-odds ratio check plot, and known goodness of fit tests) to make practitioners aware of these tools’ shortcomings in correctly identifying local dependence.

Entomological and ecological studies in a new potential zoonotic leishmaniasis focus in Torres Novas municipality, Central Region, Portugal

  • Autores: Afonso MO, Alves-Pires C, Branco S, Campino L, Cortes S, Cristóvão JM, Gonçalves L, Maia C
  • Ano de Publicação: 2013

In Portugal human and canine leishmaniasis are caused by Leishmania infantum, and Phlebotomus perniciosus and P. ariasi are the proven vectors. Three main foci were identified in eighty’s decade: Trás-os-Montes and Alto Douro region, Lisbon region and Algarve region, but according to OnLeish observatory data, canine leishmaniasis cases have been reported from several other regions, for which sand fly species and their infection rates are unknown.

Hemozoin activates the innate immune system and reduces Plasmodium berghei infection in Anopheles gambiae

  • Autores: Gonçalves L, Silveira H, Simoes ML
  • Ano de Publicação: 2015
  • Journal: Parasites & Vectors
  • Link: https://parasitesandvectors.biomedcentral.com/articles/10.1186/s13071-014-0619-y

Malaria is a worldwide infectious disease caused by Plasmodium parasites and transmitted by female Anopheles mosquitoes. The malaria vector mosquito Anophelescan trigger effective mechanisms to control completion of the Plasmodium lifecycle; the mosquito immune response to the parasite involves several pathways which are not yet well characterized. Plasmodium metabolite hemozoin has emerged as a potent immunostimulator of mammalian tissues. In this study, we aim […]

Impact of a Dengue Outbreak Experience in the Preventive Perceptions of the Community from a Temperate Region: Madeira Island, Portugal

  • Autores: Antunes L, Gonçalves L, Nazareth T, Porto G, Seixas G, Silva AC, Sousa CA, Teodósio R
  • Ano de Publicação: 2015
  • Journal: Plos Neglected Tropical Diseases
  • Link: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4388461/%20

The ability to effectively modify behaviours is increasingly relevant to attain and maintain a good health status. Current behaviour-change models and theories present two main approaches for (healthier) decision-making: one analytical/logical, and one experiential/emotional/intuitive. Therefore, to achieve an integral and dynamic understanding of the public perceptions both approaches should be considered: community surveys should measure […]
