The Temperament and Character Inventory is an internationally used personality questionnaire based on Cloninger's psychobiological theory of personality. Given some limitations of Version 9 a revised version was developed. The structural equivalence of the two versions was demonstrated from a cross-cultural perspective with 309 and 173 healthy volunteers(More)
BACKGROUND The nature of the relationship between personality and bipolar affective disorders is an important but unanswered question. METHODS We have studied personality in bipolar patients by using the Temperament and Character Inventory (TCI). TCI were administered to 100 euthymic bipolar patients and 100 controls from the normal population. RESULTS(More)
OBJECTIVE We have studied temperament and character in pathological gambling (PG). METHODS Thirty-eight DSM-IV verified pathological gamblers (31 males and 7 females; mean age 35.4 +/- 10.4 years) were tested with Cloninger's Temperament and Character Inventory (TCI). Matched controls were chosen from the normal population. RESULTS Pathological gamblers(More)
Exclusive production of 0 and J== mesons in e + p collisions has been studied with the ZEUS detector in the kinematic range 0:25 < Q 2 < 50 GeV 2 , 20 < W < 167 GeV for the 0 data and 2 < Q 2 < 40 GeV 2 , 50 < W < 150 GeV for the J== data. Cross sections for exclusive 0 and J== production have been measured as a function of Q 2 , W and t. The spin-density(More)
Using the ZEUS detector at HERA, we have studied the reaction e + p ! e + X for Q 2 > 5000 GeV 2 with a 20:1 pb ?1 data sample collected during the years 1994 to 1996. For Q 2 below 15000GeV 2 , the data are in good agreement with Standard Model expectations. For Q 2 > 35000 GeV 2 , two events are observed while 0:145 0:013 events are expected. A(More)
In deep inelastic neutral current scattering of positrons and protons at the center of mass energy of 300 GeV, we observe, with the ZEUS detector, events with a high energy neutron produced at very small scattering angles with respect to the proton direction. The events constitute a fixed fraction of the deep inelastic, neutral current event sample(More)
The e + p neutral-current deep inelastic scattering diierential cross-sections dd=dQ 2 , for Q 2 > 400 GeV 2 , dd=dx and dd=dy, for Q 2 > 400, 2500 and 10000 GeV 2 , have been measured with the ZEUS detector at HERA. The data sample of 47.7 pb ?1 was collected at a center-of-mass energy of 300 GeV. The cross-section, dd=dQ 2 , falls by six orders of(More)
