Relationship regulation in the face of eye candy: A motivated cognition framework for understanding responses to attractive alternatives

Item does not contain fulltextThe ability to maintain a satisfying and stable romantic relationship may promote health and well-being, yet, the stability of an ongoing relationship may sometimes be challenged by the availability of attractive alternative partners. We review recent findings demonstrating that people - deliberatively and automatically - display a number of strategies that help them protect their current relationship from attractive alternatives. For example, romantically involved individuals typically tend to derogate the physical attractiveness of potential alternative partners. We review different theoretical perspectives that explain why this occurs, and discuss possible mechanisms pertaining to how this occurs, focusing in particular on the independent and possibly interactive roles of motivation and self-regulatory capacity.5 p

A STRUCTURAL STUDY OF THE SMECTIC MESOPHASES OF TWO BIPHENYL COMPOUNDS AND AN X-RAY INVESTIGATION OF THE MISCIBILITY CRITERION

Les composés 4'-n-octyl-4-cyanobiphényle et 4'-n-octyloxy-4-cyanobiphényle forment des phases smectiques d'un type nouveau. Les photographies de diffraction des rayons X ne ressemblent à aucune autre. Elles possèdent un anneau intérieur bien défini (qui correspond à l'épaisseur des couches) et deux anneaux extérieurs moins définis. L'épaisseur des couches indique une structure avec des couches doubles dans lesquelles les molécules se recouvrent dans le centre. Plusieurs possibilités sont proposées pour les positions exactes des molécules. Cette phase smectique se mélange avec la phase habituelle qui existe dans le cas du 2-(4'-n-octadécyloxybenzylidèneamino) fluorène. L'observation au moyen des rayons X indique que l'épaisseur des couches varie continûment avec la composition. Bien qu'il y ait des différences entre les longueurs des molécules et les structures des deux phases smectiques, on obtient une phase homogène en mélangeant ces deux types de molécules.The biphenyl compounds 4'-n-octyl-4-cyanobiphenyl and 4'-n-octyloxy-4-cyanobiphenyl form smectic phases of a novel type. The X-ray diffraction patterns are unlike any other previously reported ; they contain a sharp inner ring (corresponding to the layer thickness) and two diffuse outer rings. The layer thickness indicates some form of bilayer structure with molecules partially overlapping in the centre of the layer. A number of alternative models for the precise molecular arrangement are suggested. This smectic phase is miscible with the conventional SA phase formed by 2-(4'-n-octadecyloxybenzylideneamino) fluorene. X-ray investigations indicated that the layer thickness changes smoothly across the composition range. In spite of the difference in molecular length and the difference between the structures of the two pure smectic phases, it appears that in mixtures there is a complete and intimate mixing of the molecules

PHASE TRANSITIONS OBSERVED ON WARMING FAST-QUENCHED MBBA

Si on refroidit rapidement la phase nématique du MBBA à la température de l'azote liquide, on obtient un solide vitreux où la structure nématique a été gelée, ainsi que le montre la diffraction des rayons X. On réchauffe ensuite le MBBA et on étudie son évolution par diffraction des rayons X et par analyse thermique différentielle. Un solide cristallin apparaît vers -14 °C, qui se transforme ensuite en la phase nématique par l'intermédiaire d'une autre phase qui pourrait être soit la phase cristalline stable, soit une phase smectique. On propose d'appeler anotropiques les transitions monotropiques qui apparaissent quand on chauffe.When the nematic phase of MBBA is rapidly cooled by exposure to liquid nitrogen a glassy solid is formed which, X-ray diffraction studies indicate, has the nematic ordering quenchedin. The sequence of events which occur upon reheating this glass was monitored using X-ray diffraction and a differential thermal technique. A transition to a metastable crystalline phase occurs at about -14 °C and this phase converts into the nematic phase via some other phase, possibly the stable crystalline phase or a smectic mesophase. We propose the name anofropic for monotropic transitions that occur on heating

Strong but insecure: Examining the prevalence and correlates of insecure attachment bonds with attachment figures

This study examined whether people can be insecurely attached to figures who are actively sought out (and not just desired) to fulfill attachment functions and whether this has negative consequences for psychological well-being. A total of 122 participants rated 3-15 relational targets on measures including the extent to which the target fulfills important attachment functions and the attachment style characterizing the relationship. Participants also completed general measures of well-being and attachment style. We specifically focused on targets who could be classified as attachment figures based on the WHOTO and examined the attachment style characterizing these relationships. Results show that a significant proportion of attachment bonds can be characterized by insecurity, which has consequences both for the extent to which these attachment figures can fulfill important attachment functions and for overall well-being. The discussion considers the implications of these results for attachment priming research and the distinction between attachment strength and security

Self-assembled columns of fullerene

Columnar mesophases based on alternating triphenylene and hexaphenyltriphenylene moieties are exceptionally stable and able to accommodate bulky side-chain substituents within the alkyl chain continuum between the columns. This paper presents a system in which the triphenylene bears a fullerene on its side-chain and the hexaphenyltriphenylene equivalent is the aza-derivative hexakis(4-nonylphenyl)dipyrazino[2,3-f : 2'3'-h] quinoxalene, PDQ9. The mesophase formed was identified as hexagonal columnar (Col(h)) by X-ray diffraction (a = 25.2 angstrom and c = 3.5 angstrom) but, in addition to the expected peaks, there is indication of a two-dimensional hexagonal superlattice with d-spacing 59 angstrom. This superlattice is believed to arise from ordering of the fullerenes within the liquid crystal matrix. It can be explained on the assumption that, to maximise fullerene-fullerene contact, the fullerenes form chains which wrap around the central column in every group of seven columns of the triphenylene : PDQ9 Col(h) array
