Addressing the Dual Primary Attachment Figure Model: An Exploration of Father Attachment

Greenwood, Vanessa N 01 June 2015 (has links)
This study attempted to investigate father attachment using the dual primary attachment figure model by examining caregiving and exploration behaviors of mothers and fathers as they relate to attachment security utilizing an archival data set of 177 young adult females. A subsequent factor analysis of the involvement scales revealed four distinct items creating the caregiving variables (one for mother and one for father) and six items creating the exploration variables. Results showed that mothers engaged in caregiving and exploration behaviors more than fathers, but their exploration predicted mother attachment more than caregiving. Fathers engaged in more caregiving than exploration, but it was their involvement in exploration that was more strongly related to father attachment. These findings, which provide partial support for the dual primary attachment figure model, suggest that father exploration is a cornerstone for the father-child attachment relationship, but also predictive of mother-child attachment. Future studies should include observational assessments of father attachment as well as exploration in current assessments of father attachment.

Pseudomonas Aeruginosa-Candida Albicans Interactions From Ecological and Molecular Perspectives

Rinzan, Fathima Faraz 20 April 2009 (has links)
Pseudomonas aeruginosa and Candida albicans have shown antagonistic relationships, both in vivo and in vitro. The interaction between P. aeruginosa and C. albicans is one of the many prokaryotic-eukaryotic interactions existing in nature and needs more research due to their complex pathogenicity in humans. In this work, we have studied growth dynamics of Candida in a mixed population of Pseudomonas and Candida, and their receptor and ligand specificities, both from an ecological and a molecular point of view. Initially, growth, viability, and morphogenesis of Candida were studied in the presence of Pseudomonas and the conditioned medium of Pseudomonas using two Candida strains, namely CAF2 and tup1 mutant. The killing effect of Pseudomonas was more pronounced on the hyphal form of Candida. However, growth of Candida was inhibited by Pseudomonas irrespective of its morphological form. The conditioned medium had no effect on the growth rate of Candida. Nevertheless, it completely inhibited the germination of Candida. The attachment of Pseudomonas to Candida was studied using different strains of both, and with Pseudomonas cells harvested at different stages of its growth. The percent attachment varied with the age of the textit Pseudomonas culture. A lecB mutant of Pseudomonas showed a two-fold reduction in attachment compared to the wild type PAK strain. Carbohydrate inhibition studies confirmed that LecB is not directly involved in the attachment mechanism, but indirectly involves through regulating the expression of other proteins required for attachment. A genomic DNA library of Pseudomonas PAO1 was screened for clones that had acquired the ability to attach to C. albicans. A clone was isolated with a small increase in attachment and was subjected to genetic analysis. It contained nucleotides 458565 to 475917 of the Pseudomonas genome including some genes of the Pil-Chp gene cluster. Seven transposon mutants that represent mutations in ChpA,B,C,D,E operon and three other ORFs were selected, and their attachment ability was tested. All seven mutants showed a reduction in attachment indicating that this was a non specific effect, which could be attributed to the in vitro manipulation of the bacteria. We conclude that the attachment of Pseudomonas to Candida is multi-factorial.

Lärande för hållbar utveckling : Behövs det en certifiering?

Romlin, Gloria January 2013 (has links)
Syfte med studien var att undersöka pedagogernas uppfattning om arbetet med hållbar utveckling genom en Grön Flagg-certifiering i förskolan. Mina frågeställningar blev därför: Hur stödjer en Grön Flagg-certifieringen arbetet mot hållbar utveckling? Hur görs barnen delaktiga i arbetet med Grön Flagg? Hur ser pedagogerna på sig själva som förebilder? Dessa frågor har besvarats genom en undersökning med kvalitativa intervjuer av åtta pedagoger i fyra olika Grön Flagg-certifierade förskolor (bland dessa en förskoleadministratör) samt kommunens miljöstrateg, tre barns egna tankar om miljö och yngre kamrater har undersöks.  Resultat har analyserats utifrån lärande för hållbar utveckling, Harts delaktighetstrappa samt Axness fostrans principer utifrån ett nytt forskningsområde kallad epigenetik med fokus på ett av dess användningsområden: barnuppfostran. Genom resultat och analys av datainsamlingen har jag funnit att en Grön Flagg-certifieringen kan stödja arbetet mot hållbar utveckling om det finns ett gemensamt synsätt inom arbetslaget, engagerade och drivande pedagoger samtidigt som man synliggör de små vardagliga insatserna i förskolan. Pedagogerna i studien anser att certifieringen utåt visat att man arbetat mot hållbar utveckling och sätter press till att arbetet genomförs.  Studiens resultat visat att barnens delaktighet i arbetet med Grön Flagg-certifiering varierar i de olika förskolorna enligt de olika projekt som beskrevs under intervjuerna. Barnens ålder eller pedagogernas inställningar på det kompetenta barnet, påverkat utsträckningen i vilken barn gjorts delaktiga i arbetet mot hållbar utveckling. Studien har visat att pedagogerna var väl medvetna om deras påverkan på barnen. De ser sina arbetsinsatser och sig själva som förebilder för barnen, men utifrån det jag funnit i min analys även för varandra för att arbete med certifieringen utvecklas. I studien gjordes ett utprövande av ämnet epigenetik samt begrepp från hjärnforskning lånades. Utifrån de olika begrepp och teorier som presenterats i studien tilldelats pedagoger rollen som primary attachment relationships samtidigt som det motiverats för pedagogers stora påverkan på barnen.
