THE IMPACT OF ATTACHMENT PARAMETERS IN CHILDHOOD ON THE PERSONALITY OF ADULTS WITH MENTAL DISORDERS

Background: Attachment parameters have an effect on later relationship patterns and the development of parameters of selfconcept and personality. In the current study the role of attachment parameters on personality dimensions was investigated, especially with respect to personality disorders. Subjects and methods: 134 psychiatric inpatients were examined on attachment and personality parameters using the schedule FEB as a questionnaire on the parental attachment and the SKI as a self-concept inventory. Results: Regression and correlation analyses suggest positive influences of parental care and negative influences of parental overprotection on the development of ego-strength in adulthood. Patients with personality disorders reported to have experienced less maternal care during their childhood and showed a trend towards a reduced ego-strength in adulthood compared to patients with others mental disorders. Conclusions: Relationships of attachment parameters in childhood with personality dimension are explorable. This approach seems meaningful for a better understanding of the development of personality disorders. Clinicians should be familiar with attachment patterns when treating people with mental disorders in order to adequately include appropriate personality dimensions in the therapy

Elevated night-time temperatures increase growth in seedlings of two tropical pioneer tree species

Increased night-time temperatures, through their influence on dark respiration, have been implicated as a reason behind decreasing growth rates in tropical trees in the face of contemporary climate change. Seedlings of two neo-tropical tree species (Ficus insipida and Ochroma pyramidale) were grown in controlled-environment chambers at a constant daytime temperature (33°C) and a range of increasing night-time temperatures (22, 25, 28, 31°C) for between 39d and 54d. Temperature regimes were selected to represent a realistic baseline condition for lowland Panama, and a rise in night-time temperatures far in excess of those predicted for Central America in the coming decades. Experiments were complemented by an outdoor open-top chamber study in which night-time temperatures were elevated by 2.4°C above ambient. Increasing night-time temperatures resulted in >2-fold increase in biomass accumulation in growth-chamber studies despite an increase in leaf-level dark respiration. Similar trends were seen in open-top chambers, in which elevated night-time temperatures resulted in stimulation of growth. These findings challenge simplistic considerations of photosynthesis-directed growth, highlighting the role of temperature-dependent night-time processes, including respiration and leaf development as drivers of plant performance in the tropics
