Healthy and maladjusted Type A behavior in adolescents

The dimensions of Type A behavior were studied in 990 randomly selected adolescents and their conceptualization was clarified in terms of achievement striving, self-concept, and sense of control. The methods used were the AFMS to evaluate Type A behavior, the Nowicki-Strickland Locus of Control Scale, and Coopersmith's Self-Esteem Inventory. Achievement striving was assessed using the questionnaire designed for this study. It was revealed that Type A consisted of two independent dimensions, both adding an equal contribution to the total score. One was an impatient, aggressive competitiveness related to a low self-esteem, low self-set achievement standards, and external locus of control. The other Type A exhibited competitiveness related to a sense of responsibility, leadership, social activity, high achievement striving, and high self-esteem. These factors may distinguish maladjusted competitiveness from healthy ambition and suggest that it is important to distinguish risk Type A individuals from Type A's who are potential leaders in society.Received Ph.D. in Psychology from the University of Helsinki, Finland.

The proximity and the directional theories of issue voting: Comparative results for the USA and Germany

Abstract In several recent studies George Rabinowitz and his co–authors challenge the 'classical' spatial model of issue voting, the proximity model, by introducing a directional model. In this article we examine whether different measurement of perceived issue positions of candidates or parties leads to diverging judgments about the predictive power of the directional model (which is claimed to be empirically superior), as compared to the proximity model, using data from the USA and Germany. The results demonstrate that the measurement preferred by Rabinowitz et al. tends to bias empirical findings in favour of directional theory. If we use a more plausible operational definition of issue positions of candidates and parties the directional model in both countries fails to turn out superior.     

Comparison of nonradioactive microtiter plate enzyme immunoassays for the sensitive detection of fentanyl

Fentanyl is a very strong opioid with analgesic properties that are approximately 80 times stronger than those of morphine and therefore is used in major surgery and treatment of pain in tumor patients. Cases of fentanyl abuse by intravenous injection, inhalation, oral or nasal application have been reported especially in the USA. Therapeutic levels of fentanyl are as low as 1 ng/ml of serum and therefore a screening test must have a detection limit below that concentration. Recently three non-radioactive enzyme immunoassays (EIAs) have become commercially available from COZART, STC and DIAGNOSTIX, all of them supplied by MAHSAN Diagnostika for evaluation with serum samples from forensic and clinical cases. A calibration curve is obtained with samples that contain 0, 0.1, 0.5, 1 and 5 ng fentanyl per ml of negative serum. The calibration curve of COZART is especially in the low range, steeper than those of STC and DIAGNOSTIX. The cut-off for all these EIAs, however, can be set at 0.5 ng/ml. After the administration of therapeutic doses, fentanyl concentrations were between 3 and more than 5 ng/ml as determined with the EIAs. The presence of the typical drugs of abuse, e.g. heroin, methadone, cocaine, cannabinoids and amphetamines including the derivatives of methylenedioxyamphetamine, don't generate false-positive results. No cross-reactivity was also observed at toxic levels of benzodiazepines and paracetamol and therapeutic levels of barbiturates, phenothiazines, antidepressants and analgesics. The EIAs tested so far appear to be suitable for the detection of fentanyl at therapeutic levels. False-positive results or cross-reactivity towards other compounds have not been observed.     

Synthesis of 2,3- and 3,4-methylenedioxyphenylalkylamines and their regioisomeric differentiation by mass spectral analysis using GC-MS-MS

3,4-methylenedioxyamphetamine (MDA) derivatives are increasingly abused central nervous system stimulants with neurotoxic properties. In recent years a number of controlled substance analogs (designer drugs) with high structural variety reached the illegal market making their identification an arduous task. The underivatized compounds give very similar or even virtually identical electron impact mass spectra containing mainly intense C(n)H(2n+2)N(+) immonium ions. Using tandem mass spectrometry (MS-MS) the additional structural information contained in the collision induced dissoziation (CID) mass spectra of molecular ions using electron impact (EI) and especially chemical ionization (CI) allowed an unequivocal differentiation of 18 studied regioisomeric 1-(methylenedioxyphenyl)-2-propanamines and 1-(methylenedioxyphenyl)-2-butanamines.Further synthetic methods are presented for 1-(3,4-methylenedioxyphenyl)-N-propyl-2-butanamine, N-isopropyl-1-(3,4-methylenedioxyphenyl)-2-butanamine and four 1-(2, 3-methylenedioxyphenyl)-2-butanamines. N-alkylated 1-(3, 4-methylenedioxyphenyl)-2-butanamine compounds (e.g. MBDB) are also known to be abused psychoactive agents (entactogenes) without the sympatomimetic effects of the 3,4-methylenedioxyamphetamines.     

Auswirkungen des Umweltrechts auf eine nachhaltige Regionalentwicklung*

Das Umweltrecht nimmt in vielfältigen Formen und Verfahren Einfluss auf die Regionalplanung als (Haupt-)Instrument nachhaltiger Regionalentwicklung. Der Beitrag beleuchtet dies unter rechtlichen Aspekten und bezieht hierzu Stellung. Die Kritik richtet sich u. a. auf die Heterogenität umweltrechtlicher Agenden und die eingeschränkte Sanktionierung von Verstößen gegen Vorgaben des Umweltrechts. * Schriftliche Fassung eines Vortrags auf dem Kongress Steuerungsimpulse für eine nachhaltige Regionalentwicklung am 24./25. 11. 2004 in Greifswald. Verf. ist Inhaber eines Lehrstuhls für öffentliches Recht und Geschäftsführender Direktor des Ostseeinstituts für Seerecht, Umweltrecht und Infrastrukturrecht, Universität Rostock.     

Homicide by ligature strangulation in Finland: offence and offender characteristics

In Finland, homicide by ligature strangulation is a rare event. The purpose of this study was to investigate recent homicide cases by ligature strangulation and to analyse offence and offender characteristics. All forensic psychiatric evaluation statements of offenders accused of ligature strangulation homicides during the 7-year period 1996--2002 (n=19) were reviewed retrospectively. Thirty-five percent of the victims were females. In four cases, the victim was the offender's intimate partner; in one case, it was the stepson; in one case, a father and in the rest of the cases (n=13), an acquaintance. None of the cases involved planning, sadism or sexual elements. In 89% of the cases, the offender was either intoxicated or on drugs at the time of the offence and in 94% of the cases, the victim was found at the scene of the killing. Of the offenders, 63% had crime history, and approximately half of the offenders had experienced parental alcohol abuse, domestic violence or previous trauma. Most of the offenders were unemployed at the time of the offence. In all, 89% were diagnosed as having personality disorder and two were schizophrenic.
