De Relatie tussen Hechting en Welbevinden bij Ouderen: De mediërende Invloed van Mindfulness en Zingeving

Empirische studies hebben aangetoond dat bij ouderen een veilige hechting positief samenhangt met het niveau van welbevinden. Hechting is een relatief stabiel en moeilijk te beïnvloeden persoonlijk kenmerk en daarom is het belangrijk om mediatoren van het verband tussen hechting en psychologische uitkomstmaten te vinden die met interventies te beïnvloeden zijn. De vraagstelling van de studie luidde: ‘Welk verband bestaat er tussen hechting en welbevinden bij ouderen en wordt dit verband gemedieerd door mindfulness en zingeving?’. De huidige studie was een survey met één meetmoment. De 210 respondenten waren 65 jaar of ouder (M = 71.25, SD = 5.42) en thuiswonend. Daarnaast mochten ze geen ernstige geheugenproblemen of een psychiatrische stoornis hebben. Via de sneeuwbalmethode werden de respondenten mondeling of schriftelijk door de onderzoeker benaderd. De vragenlijst kon anoniem online of op papier worden ingevuld. Hechting werd gemeten met de Experiences in Close Relationships-Revised (ECR-R), mindfulness met de Five Facet Mindfulness Questionnaire (FFMQ), zingeving met de Meaning in Life Questionnaire, subschaal ‘Presence of meaning in life’ (MLQ-P) en welbevinden met de Positive Affect Negative Affect Scale (PANAS) en de Satisfaction With Life Scale (SWLS). Zowel hechtingsgerelateerde angst (‘angst’) als hechtingsgerelateerde vermijding (‘vermijding’) bleek in correlatieanalyses negatief samen te hangen met mindfulness, zingeving en welbevinden. Tussen mindfulness, zingeving en welbevinden werden positieve verbanden gevonden. De (seriële) mediatieanalyse werd uitgevoerd met behulp van de macro PROCESS 2.13. Zowel het verband tussen ‘angst’ en welbevinden als tussen ‘vermijding’ en welbevinden werd volledig (serieel) gemedieerd door mindfulness en zingeving.

As Perceções sobre a Conjugalidade dos Pais, Satisfação com a Vida e as Experiências Próximas dos Filhos

Objetivos: Este estudo tem como objetivo analisar as perceções dos estudantes universitários face à conjugalidade dos pais e as suas perceções sobre as relações amorosas e a satisfação com a vida. Metodologia: o protocolo de avaliação era composto por 4 questionários: Questionário sobre a Conjugalidade dos Pais (Crespo et al, em preparação); a Escala de Satisfação com a Vida (Neto, 1993), Questionário sobre Experiências em Relações Próximas (Moreira et al, 2006) e o questionário sociodemográfico para a caracterização da amostra. Participantes: Participaram neste estudo 172 estudantes. Noventa e um são do sexo masculino e 81 do sexo feminino, com idades compreendidas entre os 18 e os 58 anos, com uma média de 23.04 (DP=6.78). Dos 172 participantes, apenas 96 estão numa relação amorosa (47 do sexo masculino e 49 do sexo feminino). Resultados: Os homens e os participantes deste estudo que fazem parte de famílias intactas percecionaram uma conjugalidade dos pais mais satisfatória; por outro lado, os participantes numa relação amorosa e os que fazem parte de famílias intactas percecionaram maior satisfação com a vida. Os participantes entre os 25 e os 58 anos, percecionaram maior evitamento nas suas relações. Conclusões: Deste trabalho conclui-se que os participantes têm uma perceção da conjugalidade dos pais positiva e estão, na globalidade, satisfeitos com a vida mas percecionam grande evitamento e preocupação nas suas relações amorosas. Conclui-se ainda que não existe uma correlação entre a perceção da conjugalidade dos pais e as experiências em relações próximas, nem com a perceção de satisfação com a vida. / Objectives: This study examines the general perceptions of university students about their parents’ marital relationship, their romantic relationships and life satisfaction. Methodology: The research protocol for this study comprised The Questionnaire about Parents’ Marital Relationship (Crespo et al., in preparation), the Life Satisfaction scale (Neto, 1993), the Questionnaire on Experiences in Close Relationships, (Moreira et al., 2006) and a sociodemographic questionnaire.. Participants: 172 students participated in this study, of which 91 were male and 81 female, aged between 18 and 58 years old, with an average age of 23.04 (SD = 6.78). From the total of 172 participants, only 96 were in a romantic relationship; out of these 47 were male and 49 female. Results: Men and participants from intact families reported a better perception of parents’ marital relationship; participants in a romantic relationship and from intact families had greater life satisfaction and participants between 25 and 58 years old perceived more avoidance in their relationships. Conclusion: Participants have a positive perceptions of parents’ marital relationship are satisfied with life, however they perceive anxiety and avoidance in their romantic relationships. We also conclude that there is no correlation between the perception of parents’ marital relationship and their experiences in close relationships and perception of life satisfaction.

Vinculação, Estilos Educativos Parentais e Esquemas Precoces Mal Adaptativos em Reclusos

Introdução: Sobretudo estudos internacionais focam a importância da vinculação e dos estilos educativos parentais no desenvolvimento de comportamentos delinquentes e antissociais. Em Portugal, alguns estudos focados na população reclusa, analisam, separadamente, estilos educativos parentais, personalidade e esquemas precoces mal adaptativos mas, segundo sabemos, nenhum explora, simultaneamente, a vinculação, os estilos educativos parentais e os esquemas precoces mal adaptativos nesta população. São nossos objetivos caracterizar uma amostra de reclusos quanto à vinculação em diferentes relacionamentos, estilos educativos parentais e esquemas precoces mal adaptativos (EPM) e, sobretudo, explorar associações entre estas três variáveis (e destas com variáveis sociodemográficas, familiares, clínicas e relativas à pena). Metodologia: 44 reclusos do sexo masculino (M = 37,3 anos; DP = 10,98; variação = 23-67) preencheram voluntariamente um questionário sociodemográfico e os seguintes instrumentos: EMBU – Memórias de Infância, Experiências em Relações Próximas - Questionário de Estruturas Relacionais e Questionário de Esquemas de Young (QEY). Resultados: Verificou-se, quanto às associações entre vinculação e estilos educativos parentais que: menor suporte emocional paterno associou-se a maior evitamento pai, evitamento mãe e evitamento companheira; menor suporte emocional materno associou-se a maior evitamento mãe, evitamento pai, ansiedade mãe e ansiedade pai; maior rejeição paterna associou-se a maior evitamento mãe, evitamento pai, ansiedade mãe e ansiedade pai; maior rejeição materna associou-se a maior evitamento pai e evitamento mãe. No que toca às associações entre as dimensões de vinculação e EPM, é de enfatizar a associação positivas entre os EPM do domínio distanciamento e rejeição com o evitamento mãe, ansiedade mãe e ansiedade pai, particularmente, os EPM de abandono, desconfiança/abuso e isolamento social, por consistentemente se associaram às dimensões de vinculação. No domínio autonomia e desempenho deteriorados, o fracasso e a dependência/incompetência associaram-se positivamente ao evitamento mãe, a dependência/incompetência à ansiedade pai e o fracasso ao evitamento companheira. Quanto ao domínio limites deteriorados, a grandiosidade associou-se positivamente à ansiedade pai. No domínio vigilância e inibição o pessimismo/negativismo correlacionou-se positivamente com a ansiedade mãe e pai e a autopunição com a ansiedade mãe. Quanto às associações entre dimensões de estilos educativos parentais e os EPM, o domínio distanciamento e rejeição apresentou, de novo resultados relevantes: menores níveis de suporte emocional materno associaram-se a maiores níveis de privação emocional; maiores níveis de rejeição e sobreproteção materna e paterna a maiores os níveis de abandono; maiores níveis de rejeição materna e paterna a maiores níveis de desconfiança/abuso; maiores níveis de rejeição materna e sobreproteção materna e paterna a maiores níveis de isolamento social; maiores níveis de rejeição e sobreproteção paterna a maiores níveis de defeito. Enfatiza-se, também, a associação entre níveis maiores de rejeição paterna e os EPM de grandiosidade, padrões excessivos e pessimismo. Maiores níveis de rejeição materna associaram-se a maiores níveis de pessimismo e autopunição. Discussão: Embora numa amostra pequena, este estudo explorou, pela primeira vez, numa amostra de reclusos portugueses, em simultâneo, associações entre a vinculação, os estilos educativos parentais e os esquemas precoces mal adaptativos. O domínio esquemático distanciamento e rejeição parece ser o mais influenciado pela vinculação estabelecida em diferentes relacionamentos e pelos estilos educativos parentais. / Introduction: Mainly international studies focus on the importance of attachment and parental rearing styles in the development of delinquent and antisocial behaviors. In Portugal some studies focused in the inmate population analyze, separately, parental rearing styles, personality and early maladaptive schemas but, to our knowledge, none simultaneously explores attachment, parental rearing styles and early maladaptive schemas in this population. It is our objective to characterize a sample of inmates concerning attachment in different relationships, parental rearing styles and early maladaptive schemas (EMS) and, above all, explore associations between this three variables (and also with sociodemographic, family, clinic and sentence related variables). Methodology: 44 male inmates (M = 37,3 years; SD = 10,98; variation = 23-67) voluntarily filled in a sociodemographic questionnaire and the following instruments: EMBU – Childhood Memories, Experiments in Close Relationships – Structural Relationship Form and the Young Schema Questionnaires (YSQ) Results: we verified, regarding associations between attachment and parental rearing styles that: less paternal emotional support associated with higher father avoidance (in attachment), mother avoidance and partner avoidance; less maternal emotional support associated with higher mother avoidance, father avoidance, mother anxiety and father anxiety; higher paternal rejection associated with higher mother avoidance, father avoidance, mother anxiety and father anxiety; higher mother rejection associated with father avoidance and mother avoidance. Regarding associations between attachment dimensions and EMS, we emphasize positive associations between EMS in the disconnection and rejection domain with mother avoidance, mother anxiety and father anxiety, particularly, the abandonment, distrust/abuse and social isolation EMS, as they were consistently associated with the this attachment dimension. In the impaired autonomy and performance domain, the failure and dependency/incompetence EMS are positively associated with mother avoidance, the dependence/incompetence EMS to father anxiety and failure to partner avoidance. About the impaired limits domain, grandiosity EMS positively associated with father anxiety. In the overvigilance and inhibition domain, pessimist/negativism EMS positively correlated with mother and father anxiety and self-punishment EMS with mother anxiety. About the associations between parental rearing styles and the EMS, the disconnection and rejection domain presented again relevant results: lower levels of maternal emotional support associated with higher levels of emotional deprivation; higher levels of maternal and paternal rejection and overprotection associated with higher levels of abandonment; higher levels of maternal and paternal rejection associated with higher levels of distrust/abuse; higher levels of maternal rejection and maternal and paternal overprotection associated with higher levels of social isolation; higher levels of paternal rejection and overprotection associated with higher levels of defectiveness. We also emphasize the association between higher levels of paternal rejection and the grandiosity, excessive patterns and pessimism EMS. Higher levels of maternal rejection associated with higher levels of pessimism and self-punishment EMS. Discussion: Although in a small sample, this study explored, for the first time, in sample of Portuguese inmates, simultaneously, the associations between attachment, parental rearing styles and early maladaptive schemas. The schematic domain of disconnection and rejection seems to be the most influenced by the established attachment in different relationships and by parental rearing styles.

Dyades d’attachement et satisfaction sexuelle chez des couples en psychothérapie

Le présent mémoire doctoral a comme principal objectif de déterminer si la dynamique d’attachement entre les deux conjoints (i.e., le pairage des styles d’attachement de chacun : sécure, préoccupé, craintif et détaché) permet de mieux rendre compte de l’insatisfaction sexuelle que le style d’attachement de chacun, pris séparément. Afin d’y parvenir, les conjoints seront pairés quant à leur style d’attachement afin de créer des pairages (3 et 16 pairages). Par la suite, ces pairages seront comparés sur le plan de leur insatisfaction sexuelle tout en tenant compte du genre des conjoints et de certaines covariables (durée de la relation et statut marital). L’échantillon de l’étude se compose de 1078 individus hétérosexuels qui consultent en psychothérapie conjugale (539 couples). Deux questionnaires (le Questionnaire sur les expériences d’attachement amoureux (QEAA) (Experiences in close relationships (ECR) ; Brennan, et al., 1998; traduit par Lafontaine & Lussier, 2003) et le Questionnaire de Hudson (Index of Sexual Satisfaction (ISS); Hudson, 1978; traduit par Comeau & Boisvert, 1985)) sont utilisés afin de mesurer les représentations d’attachement des participants et le degré de l’insatisfaction d’un individu par rapport à sa relation avec un partenaire. Dans un premier temps, une analyse factorielle exploratoire permet de vérifier que le Questionnaire de Hudson comporte une seule composante dans sa structure. Ensuite, une ANOVA à mesures répétées pour le genre des participants (3 (pairage) X 2 (femmes vs hommes)) détermine s’il existe des différences de moyennes entre les dyades d’attachement, et ce, selon le sexe. Les résultats montrent que les pairages vivant le plus d’insatisfaction sexuelle sont celles composés de deux conjoints insécures et ceux étant plus satisfaits sont ceux unissant deux partenaires sécures. Enfin, une ANOVA à mesures répétées pour le genre des participants (16 (pairage) X 2 (femmes vs hommes)) est employée dans le but de déterminer s’il existe des différences de moyennes entre les dyades d’attachement des participants. Les femmes les plus satisfaites sont les femmes préoccupées jumelées à un homme sécure et celles les plus insatisfaites sexuellement sont dans un pairage craintive-craintif. Chez les hommes, les satisfaits sexuellement sont issus du pairage composé d’une femme préoccupée et d’un homme préoccupé et ceux étant les plus insatisfaits de leur sexualité sont les détachés jumelés à une femme détachée. Les analyses présentement également les taux de prévalence des types d’attachement, mais aussi des pairages de ces mêmes représentations, et ce, dans une population clinique. Le type d’attachement sécure semble donc avoir un effet protecteur pour l’insatisfaction sexuelle, tout comme le style préoccupé. Toutefois, la détresse sexuelle apparaît être plus présente au sein des types détaché et craintif.

Double Hybrid Functionals and the Π-System Bond Length Alternation Challenge: Rivaling Accuracy of Post-HF Methods

Predicting accurate bond length alternations (BLAs) in long conjugated oligomers has been a significant challenge for electronic-structure methods for many decades, made particularly important by the close relationships between BLA and the rich optoelectronic properties of π-delocalized systems. Here, we test the accuracy of recently developed, and increasingly popular, double hybrid (DH) functionals, positioned at the top of Jacobs Ladder of DFT methods of increasing sophistication, computational cost, and accuracy, due to incorporation of MP2 correlation energy. Our test systems comprise oligomeric series of polyacetylene, polymethineimine, and polysilaacetylene up to six units long. MP2 calculations reveal a pronounced shift in BLAs between the 6-31G(d) basis set used in many studies of BLA to date and the larger cc-pVTZ basis set, but only modest shifts between cc-pVTZ and aug-cc-pVQZ results. We hence perform new reference CCSD(T)/cc-pVTZ calculations for all three series of oligomers against which we assess the performance of several families of DH functionals based on BLYP, PBE, and TPSS, along with lower-rung relatives including global- and range-separated hybrids. Our results show that DH functionals systematically improve the accuracy of BLAs relative to single hybrid functionals. xDH-PBE0 (N4 scaling using SOS-MP2) emerges as a DH functional rivaling the BLA accuracy of SCS-MP2 (N5 scaling), which was found to offer the best compromise between computational cost and accuracy the last time the BLA accuracy of DFT- and wave function-based methods was systematically investigated. Interestingly, xDH-PBE0 (XYG3), which differs to other DHs in that its MP2 term uses PBE0 (B3LYP) orbitals that are not self-consistent with the DH functional, is an outlier of trends of decreasing average BLA errors with increasing fractions of MP2 correlation and HF exchange.

The Associations Between the Maladaptive Personality Dimensions of Neediness and Self-Criticism, Defense Styles, Selfobject Needs, and Attachment Styles in an Iranian Sample

The present study extends previous findings by examining whether defense styles, selfobject needs, attachment styles relate to Neediness and Self-Criticism, as maladaptive personality dimensions focused, respectively, on relatedness and self-definition in an Iranian sample. Three hundred and fifty two participants completed a socio-demographic questionnaire as well as the Persian forms of the Depressive Experiences Questionnaire, Experience of Close Relationships-Revised, Defense Style Questionnaire, Beck Depression Inventory–II and Selfobject Needs Inventory. Two Multiple Linear Regression Analyses, entering Self-criticism and Neediness as criterion variables, were computed. According to the results high Attachment anxiety, high Immature defenses, high depressive symptoms, and high need for idealization were related to self-criticism, and explained 47% of its variance. In addition, high attachment anxiety, low mature defenses, high neurotic defenses, high avoidance of mirroring, and low avoidance of idealization/twinship were related to neediness, and explained 40% of its variance. A Principal Component Analysis was performed, entering all the studied variables. Three factors emerged; one describing a maladaptive form of psychological functioning and two describing more mature modes of psychological functioning. The results are discussed in their implications for the understanding of neediness and self-criticism as maladaptive personality dimensions focused, respectively, on relatedness and self-definition.

O PAPEL DA COMUNICAÇÃO FACE A FACE NAS ORGANIZAÇÕES NO CONTEXTO DA SOCIEDADE MIDIATIZADA

Este estudo trata da comunicação face a face nas organizações sob diferentes abordagens teóricas. Considera a perspectiva da simultaneidade dos meios, já que as empresas utilizam diversos canais para dialogar com seus públicos de interesse. Leva em conta o fenômeno da midiatização, que reestrutura o modo como as pessoas se relacionam na sociedade contemporânea. O objetivo geral da pesquisa é sistematizar papeis potencialmente exercidos pela interação face a face e conhecer algumas circunstâncias que envolvem sua prática nas organizações. Por se tratar de uma tese teórica, a pesquisa bibliográfica se apresenta como um dos principais procedimentos metodológicos; análises de casos empíricos e um estudo de caso desenvolvido na Embrapa Pantanal constituem situações ilustrativas. Conclui-se que a comunicação face a face nas empresas ocorre de forma simultânea e combinada a outros canais de comunicação, porém, ela proporciona resultados práticos e filosóficos ainda pouco explorados. É rara a utilização estratégica de contatos presenciais como mecanismo para estabelecer relacionamentos, conhecer as reações alheias e ajustar a comunicação, aliar o discurso corporativo às práticas empresariais e avaliar o contexto onde se desenvolvem as interações, o que pode ser decisivo para a comunicação organizacional.

Serotonergic activity influences the cognitive appraisal of close intimate relationships in healthy adults

Our results suggest that central serotonin activity influences the appraisal of close intimate partnerships, raising the possibility that serotonergic dysfunction contributes to altered cognitions about relationships in psychiatric illnesses.

Description and Phylogenetic Relationships of a New Genus and Species of Lizard (Squamata, Gymnophthalmidae) from the Amazonian Rainforest of Northern Brazil

Marinussaurus curupira, a new genus and species of Gymnophthalmidae lizard is described from Iranduba, state of Amazonas, Brazil. The genus is characterized by an elongate body; short and stout pentadactyl limbs; all digits clawed; single frontonasal; two prefrontals; absence of frontoparietals; interparietal and parietals forming a straight posterior margin, with interparietal shorter than parietals; distinctive ear opening and eyelid; few temporals; three pairs of chin shields; nasal divided; a distinct collar; smooth, mainly hexagonal, dorsal scales; smooth quadrangular ventral scales; two precloacal and three femoral pores on each side in males; pores between three or four scales. Parsimony (PAR) and partitioned Bayesian (BA) phylogenetic analyses with morphological and molecular data recovered the new genus as a member of the Ecpleopodini radiation of the Cercosaurinae. A close relationship of the new genus with Arthrosaura is postulated.

Phylogenetic relationships of Trypanosoma chelodina and Trypanosoma binneyi from Australian tortoises and platypuses inferred from small subunit rRNA analyses

Trypanosome infections are often difficult to detect by conventional microscopy and their pleomorphy often confounds differential diagnosis. Molecular techniques are now being used to diagnose infections and to determine phylogenetic relationships between species. Complete small subunit rRNA gene sequences were determined for isolates of Trypanosoma chelodina from the Brisbane River tortoise (Emydura signata), the saw-shelled tortoise (Elseya latisternum), and the eastern snake-necked tortoise (Chelodina longicollis) from southeast Queensland, Australia. Partial sequence data were also obtained for T. binneyi from a platypus (Ornithorhynchus anatinus) from Tasmania. Phylogenetic relationships between T. chelodina, T. binneyi and other species were examined by maximum parsimony and likelihood methods. The Australian tortoise and platypus trypanosomes did not exhibit any close phylogenetic relationships with those of mammals, reptiles or amphibians, but were closely related to each other, and to fish trypanosomes. This contra-indicates their co-evolution with their vertebrate hosts but does not exclude co-evolution with different groups of invertebrate vectors, notably insects and leeches.

Phylogenetic analysis of evolutionary relationships of the planctomycete division of the domain bacteria based on amino acid sequences of elongation factor Tu

Sequences from the tuf gene coding for the elongation factor EF-Tu were amplified and sequenced from the genomic DNA of Pirellula marina and Isosphaera pallida, two species of bacteria within the order Planctomycetales. A near-complete (1140-bp) sequence was obtained from Pi. marina and a partial (759-bp) sequence was obtained for I. pallida. Alignment of the deduced Pi. marina EF-Tu amino acid sequence against reference sequences demonstrated the presence of a unique Il-amino acid sequence motif not present in any other division of the domain Bacteria. Pi. marina shared the highest percentage amino acid sequence identity with I. pallida but showed only a low percentage identity with other members of the domain Bacteria. This is consistent with the concept of the planctomycetes as a unique division of the Bacteria. Neither primary sequence comparison of EF-Tu nor phylogenetic analysis supports any close relationship between planctomycetes and the chlamydiae, which has previously been postulated on the basis of 16S rRNA. Phylogenetic analysis of aligned EF-Tu amino acid sequences performed using distance, maximum-parsimony, and maximum likelihood approaches yielded contradictory results with respect to the position of planctomycetes relative to other bacteria, It is hypothesized that long-branch attraction effects due to unequal evolutionary rates and mutational saturation effects may account for some of the contradictions.

Biogeographic and palaeoclimatic relationships of the Middle Pliocene ichthyofauna of the Samoggia Torrent (Bologna, Italy)

New Middle Pliocene ichthyofauna (2.4-2.2 Ma) from central-eastern Italy (Samoggia Torrent, Bologna) are described. These ichthyolites were found in a rather thin laminated layer that was deposited after the 2.4 Ma climatic crisis. The origin of this deposit, in which 31 taxa have been classified, is to be related to anoxic events on a regional and, probably, supraregional scale. This ichthyofaunistic association, which consists of living genera, is characterized by a clearcut predominance of mesopelagic species. The palaeoclimatic characters of these ichthyofauna indicate subtropical-type waters, while from a palaeobiogeographic point of view there is a close relationship with the present-day Atlantic-Mediterranean bioprovince. The Samoggia deposit has yielded six taxa that are absent or only occasionally present in the Mediterranean: one of these, Spratelloides gracilis, is exclusive of the Indo-Pacific bioprovince.
