Role of state and trait attachment dimensions on involvement in a close relationship

The aim of the study was to investigate the association between trait and state attachment features and involvement in a couple-relationship. Eighty-four participants of different nationalities completed Childhood Trauma Questionnaire (CTQ), Toronto Alexithymia Scale (TAS-20), Attachment Style Questionnaire (ASQ), Experiences in Close Relationships-Revised (ECR-R), State Adult Attachment Measure (SAAM) and a personal questionnaire focused on involvement and amount of time spent in a couple-relationship. Results of the study showed that trait attachment features predicted involvement in a close relationship and the presence of a couple relationship predicted attachment state dimensions. Correlation analyses showed that the involvement in couple relationship was associated to CTQ Physical Neglect and SAAM Anxiety while participants without a partner had higher scores on CTQ Emotional Abuse, ECR- R Avoidance and SAAM Avoidance. Regression analyses showed that trait attachment features predicted time spent in a close relationship, while time spent in relationship predicted state attachment dimensions. Moreover, regression analysis showed that SAAM Security was predicted by ECR-R scales only in the sample of participants involved in a couple relationship

2‐(Hydroxyimino)aldehydes: photochemical and physico‐chemical properties of a versatile functional group for monomer design

In the context of our research on stimuli-responsive polymers bearing the 2-(hydroxyimino)aldehyde (HIA) 2 group, we explore the photochemical behavior and physico-chemical properties of a number of HIAs. Interpretation of experimental data is supported by quantum mechanical calculations. HIAs are expected to undergo photoisomerization, chelate metal ions, yield hydrogen-bonded dimers or oligomers, exhibit relatively low pKas, and form >C=NO• radicals through OH hydrogen abstraction or oxidation of the oximate ion. Besides the well-established E/Z oxime photoisomerism, we observe a Norrish-Yang cyclization resulting in cyclobutanol oximes, to our knowledge not described in previous literature. Acidity, Bond Dissociation Enthalpies and electrochemical properties of HIAs are compared to literature data on simple oximes. Results are discussed in relation to the many potential applications for HIAs, with emphasis on the synthesis of novel HIA-containing responsive polymers
