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
Ionization wave propagation on a micro cavity plasma array
Microcavity plasma arrays of inverse pyramidal cavities have been fabricated
in p-Si wafers. Each cavity acts as a microscopic dielectric barrier discharge.
Operated at atmospheric pressure in argon and excited with high voltage at
about 10 kHz, each cavity develops a localized microplasma. Experiments have
shown a strong interaction of individual cavities, leading to the propagation
of wave-like optical emission structures along the surface of the array. This
phenomenon is numerically investigated using computer simulation. The observed
ionization wave propagates with a speed of about 5 km/s, which agrees well the
experimental findings. It is found that the wave propagation is due to
sequential contributions of a drift of electrons followed by drift of ions
between cavities seeded by photoemission of electrons by the plasma in adjacent
cavities
Nest use is influenced by the positions of nests and drinkers in aviaries
The influence of the nest location and the placement of nipple drinkers on nest use by laying hens in a commercial aviary was assessed. Twenty pens in a laying hen house were equipped with the same commercial aviary system, but the pens differed in the nest location and the placement of nipple drinkers. Nests were placed along the walls in 10 pens, and nipple drinkers were installed in front of the nests in 5 of these pens. The other 10 pens were equipped with nests placed on a tier within the aviary (integrated nests). Nipple drinkers were installed in front of the nests in 5 of these pens. A total of 225 Lohmann Selected Leghorns were housed per pen. The hens were offered 4 nests per pen: 2 facing the service corridor of the laying hen house and 2 facing the outdoor area. The numbers of nest eggs and mislaid eggs were counted daily per pen. At 25, 36, and 43 wk of age, the nest platforms were videotaped and the behavior of laying hens in front of the nests was analyzed. The nest location affected the stationary and locomotive behaviors in front of the nests. Hens in front of the integrated nests and the nests with drinkers displayed more stationary behaviors than hens in front of wall-placed nests or nests without drinkers. No difference in the number of nest eggs could be detected, but the integration of the nests inside the aviary led to a more even distribution of hens while nest searching. In the pens with wall-placed nests, significantly more hens laid eggs in the nests at the wall near the service corridor than at the wall near the outdoor area. Due to this imbalance, crowding in front of the preferred nests occurred and pushing and agonistic interactions on the nest platforms were significantly more frequent. Placement of nipple drinkers in front of nests had no effect on the number of eggs laid in those nest
Angular momenta, dynamical masses, and mergers of brightest cluster galaxies
Using the VIMOS integral field unit (IFU) spectrograph on the Very Large Telescope, we have spatially mapped the kinematic properties of 10 nearby brightest cluster galaxies (BCGs) and 4 BCG companion galaxies located within a redshift of z = 0.1. In th
Spatially resolved simulation of a radio frequency driven micro atmospheric pressure plasma jet and its effluent
Radio frequency driven plasma jets are frequently employed as efficient
plasma sources for surface modification and other processes at atmospheric
pressure. The radio-frequency driven micro atmospheric pressure plasma jet
(APPJ) is a particular variant of that concept whose geometry allows
direct optical access. In this work, the characteristics of the APPJ
operated with a helium-oxygen mixture and its interaction with a helium
environment are studied by numerical simulation. The density and temperature of
the electrons, as well as the concentration of all reactive species are studied
both in the jet itself and in its effluent. It is found that the effluent is
essentially free of charge carriers but contains a substantial amount of
activated oxygen (O, O and O). The simulation results are
verified by comparison with experimental data
Mutual Zonated Interactions of Wnt and Hh Signaling Are Orchestrating the Metabolism of the Adult Liver in Mice and Human
The Hedgehog (Hh) and Wnt/β-Catenin (Wnt) cascades are morphogen pathways whose pronounced influence on adult liver metabolism has been identified in recent years. How both pathways communicate and control liver metabolic functions are largely unknown. Detecting core components of Wnt and Hh signaling and mathematical modeling showed that both pathways in healthy liver act largely complementary to each other in the pericentral (Wnt) and the periportal zone (Hh) and communicate mainly by mutual repression. The Wnt/Hh module inversely controls the spatiotemporal operation of various liver metabolic pathways, as revealed by transcriptome, proteome, and metabolome analyses. Shifting the balance to Wnt (activation) or Hh (inhibition) causes pericentralization and periportalization of liver functions, respectively. Thus, homeostasis of the Wnt/Hh module is essential for maintaining proper liver metabolism and to avoid the development of certain metabolic diseases. With caution due to minor species-specific differences, these conclusions may hold for human liver as well
Individual and occupational risk factors for knee osteoarthritis: results of a case-control study in Germany
A time series of hydroxylamine (NH2OH) in the southwestern Baltic Sea
Hydroxylamine (NH(2)OH) is an intermediate of the marine nitrogen cycle and in marine environments dissolved NH(2)OH is short-lived. In order to investigate the distribution of NH(2)OH under varying oxygen conditions, its seasonal variability was investigated on a monthly basis from July 2005 to May 2006 at the time series station Boknis Eck located in the Eckernforde Bay (southwestern Baltic Sea). NH(2)OH concentrations were generally low and close to the detection limit. However, a pronounced increase was observed after the seasonal thermohaline stratification period with low oxygen/anoxic conditions in the deep layers was terminated in November 2005. The increase of NH(2)OH was associated with the re-oxygenation of the water column. We conclude that NH(2)OH was produced in-situ during nitrification. We suggest that the detection of significant amounts of NH(2)OH can be used as an indicator for a "fresh" nitrifying system
Compact radio cores: from the first black holes to the last
One of the clearest signs of black hole activity is the presence of a compact
radio core in the nuclei of galaxies. With the Square Kilometer Array (SKA)
these cores can be used to study the evolution of black holes throughout the
universe and even to detect the very first generation of supermassive black
holes. We start by introducing some of the basic properties of compact radio
cores and how they scale with accretion power. The relative contribution of
jets and radio cores to the Spectral Energy Distribution (SED) is strongest in
sub-Eddington black holes but also present in the most luminous objects. Radio
and X-rays are correlated as a function of black hole mass such that the most
massive black holes are most suited for radio detections. We present a radio
core luminosity function for the present universe down to the least luminous
AGN. The SKA will essentially detect all dormant black holes in the local
universe, such as that in our Milky Way, out to several tens of Megaparsecs. It
will also be able to see black holes in the making at redshifts z>10 for black
hole masses larger than 10^7 M_sun. Finally, we suggest that the first
generation of black holes may have jets that are frustrated in their dense
environment and thus appear as Gigahertz-Peaked-Spectrum (GPS) sources. Since
their intrinsic size and peak frequency are related and angular size and
frequency scale differently with redshift, there is a unique region in
parameter space that should be occupied by emerging black holes in the epoch of
reionization. This can be well probed by radio-only methods with the SKA.
