Validität der Strukturachse der Operationalisierten Psychodynamischen Diagnostik (OPD-2)

In dieser Studie mit 125 Probanden wurde die externe Validität der OPD-2 Strukturachse und ihrer acht Subdimensionen anhand vergleichbarer bzw. verwandter Konstrukte (Selbstbeurteilungs-Fragebögen) erfasst. Mit nur einer Ausnahme zeigten sich signifikante Korrelationen zwischen den einzelnen Skalen der verwendeten Fragebögen und den korrespondierenden Subdimensionen der OPD-2 Strukturachse. Zudem fanden sich signifikante Zusammenhänge zwischen dem Gesamtstrukturniveau der OPD-2 und dem BPI (Borderline Persönlichkeitsinventar)-Gesamtscore sowie den Subskalen „Primitive Abwehr und Objektbeziehungen“, „Identitätsdiffusion“ und „Angst vor Nähe“. Die Ergebnisse unterstützen die Annahme, dass die Strukturachse der OPD-2 eine valide Methode zur Erfassung des Strukturniveaus der Patienten im klinischen Alltag darstellt

Reliability and validity of the German version of the Structured Interview of Personality Organization (STIPO)

Background: The assessment of personality organization and its observable behavioral manifestations, i.e. personality functioning, has a long tradition in psychodynamic psychiatry. Recently, the DSM-5 Levels of Personality Functioning Scale has moved it into the focus of psychiatric diagnostics. Based on Kernberg's concept of personality organization the Structured Interview of Personality Organization (STIPO) was developed for diagnosing personality functioning. The STIPO covers seven dimensions: (1) identity, (2) object relations, (3) primitive defenses, (4) coping/rigidity, (5) aggression, (6) moral values, and (7) reality testing and perceptual distortions. The English version of the STIPO has previously revealed satisfying psychometric properties. Methods: Validity and reliability of the German version of the 100-item instrument have been evaluated in 122 psychiatric patients. All patients were diagnosed according to the Diagnostic and Statistical Manual for Mental Disorders (DSM-IV) and were assessed by means of the STIPO. Moreover, all patients completed eight questionnaires that served as criteria for external validity of the STIPO. Results: Interrater reliability varied between intraclass correlations of .89 and 1.0, Crohnbach's a for the seven dimensions was .69 to .93. All a priori selected questionnaire scales correlated significantly with the corresponding STIPO dimensions. Patients with personality disorder (PD) revealed significantly higher STIPO scores (i.e. worse personality functioning) than patients without PD; patients cluster B PD showed significantly higher STIPO scores than patients with cluster C PD. Conclusions: Interrater reliability, Crohnbach's a, concurrent validity, and differential validity of the STIPO are satisfying. The STIPO represents an appropriate instrument for the assessment of personality functioning in clinical and research settings

Social challenges for business in the age of populism

The last decade has seen the rise of populist leaders and parties around the world. Despite some setbacks, such as the electoral defeats of U.S. President Donald Trump in 2020 and President Jair Bolsonaro of Brazil in 2022, populism continues to exert significant influence in these countries and to gain ground in other nations through electoral processes (e.g., Orbán in Hungary, Meloni in Italy, and Erdoğan in Turkey in 2022–2023). Even in countries where populists fail to control executive or legislative power, they can be highly influential in shaping the policies of mainstream parties either directly through participation in coalitions (e.g., in Finland) or from outside the government by threatening future electoral defeats (e.g., in Austria, the Netherlands, Belgium).<br/

From bi-layer to tri-layer Fe nanoislands on Cu3Au(001)

Self assembly on suitably chosen substrates is a well exploited root to control the structure and morphology, hence magnetization, of metal films. In particular, the Cu3Au(001) surface has been recently singled out as a good template to grow high spin Fe phases, due to the close matching between the Cu3Au lattice constant (3.75 Angstrom) and the equilibrium lattice constant for fcc ferromagnetic Fe (3.65 Angstrom). Growth proceeds almost layer by layer at room temperature, with a small amount of Au segregation in the early stage of deposition. Islands of 1-2 nm lateral size and double layer height are formed when 1 monolayer of Fe is deposited on Cu3Au(001) at low temperature. We used the PhotoElectron Diffraction technique to investigate the atomic structure and chemical composition of these nanoislands just after the deposition at 140 K and after annealing at 400 K. We show that only bi-layer islands are formed at low temperature, without any surface segregation. After annealing, the Fe atoms are re-aggregated to form mainly tri-layer islands. Surface segregation is shown to be inhibited also after the annealing process. The implications for the film magnetic properties and the growth model are discussed.Comment: Revtex, 5 pages with 4 eps figure

Lethal Influenza Virus Infection in Macaques Is Associated with Early Dysregulation of Inflammatory Related Genes

The enormous toll on human life during the 1918–1919 Spanish influenza pandemic is a constant reminder of the potential lethality of influenza viruses. With the declaration by the World Health Organization of a new H1N1 influenza virus pandemic, and with continued human cases of highly pathogenic H5N1 avian influenza virus infection, a better understanding of the host response to highly pathogenic influenza viruses is essential. To this end, we compared pathology and global gene expression profiles in bronchial tissue from macaques infected with either the reconstructed 1918 pandemic virus or the highly pathogenic avian H5N1 virus A/Vietnam/1203/04. Severe pathology was observed in respiratory tissues from 1918 virus-infected animals as early as 12 hours after infection, and pathology steadily increased at later time points. Although tissues from animals infected with A/Vietnam/1203/04 also showed clear signs of pathology early on, less pathology was observed at later time points, and there was evidence of tissue repair. Global transcriptional profiles revealed that specific groups of genes associated with inflammation and cell death were up-regulated in bronchial tissues from animals infected with the 1918 virus but down-regulated in animals infected with A/Vietnam/1203/04. Importantly, the 1918 virus up-regulated key components of the inflammasome, NLRP3 and IL-1β, whereas these genes were down-regulated by A/Vietnam/1203/04 early after infection. TUNEL assays revealed that both viruses elicited an apoptotic response in lungs and bronchi, although the response occurred earlier during 1918 virus infection. Our findings suggest that the severity of disease in 1918 virus-infected macaques is a consequence of the early up-regulation of cell death and inflammatory related genes, in which additive or synergistic effects likely dictate the severity of tissue damage
