Variable adverse effects in subjects after ingestion of equal doses of Argyreia nervosa seeds

As the new drug Spice hit the market in 2006 and was a hot topic in the media, the general issue of legal highs has been brought to the attention of a large number of (young) people. One of these so called legal highs are the seeds of Argyreia nervosa, also known as Hawaiian Baby Woodrose, which contains the psychotropic alkaloid lysergic acid amide (LSA). A study was designed to assess how driving ability is affected by Argyreia nervosa. However, the study could not be continued due to severe adverse effects in 3 of 4 subjects, such as cardiovascular dysregulation in two and a psychosis like state in one subject. All of the participants recovered completely within 9h after ingestion. Despite body normalized doses interindividually highly differing reactions in type and intensity were observed. Furthermore, fluctuating alkaloid contents in seeds and multi-drug intoxications make the use of this legal high far more dangerous than commonly believed.     

Recovery of DNA and fingerprints from touched documents

This study investigated the various factors affecting DNA profiling from DNA recovered from fingerprints deposited on paper before and after fingerprint enhancement treatments. The DNeasy^® plant mini kit (QIAGEN^®) was found to improve DNA recovery from paper by over 150% compared with the QIAamp^® mini kit. A significant decrease in the amount of DNA recovered was observed following treatment with DFO and/or Ninhydrin. This decrease in yield did not have a comparably significant effect on the quality of the SGM Plus™ profiles. Furthermore, this study found that whilst certain paper types, such as newspaper, magazine and filter paper allowed for the good recovery of DNA, common office paper and white card, strongly interfered with the recovery of DNA resulting in poor quality profiles.     

What Stops the Torture?

States whose agents engage in torture in a given year have a 93% chance of continuing to torture in the following year. What leads governments to stop the use of torture? We focus on the principal–agent relationship between the executive and the individuals responsible for supervising and interrogating state prisoners. We argue that some liberal democratic institutions change the probability that leaders support the creation of institutions that discourage jailers and interrogators from engaging in torture, thus increasing the probability of a state terminating its use of torture. These relationships are strongly conditioned by the presence of violent dissent; states rarely terminate the use of torture when they face a threat. Once campaigns of violent dissent stop, however, states with popular suffrage and a free press are considerably more likely to terminate their use of torture. Also given the end of violent dissent, the greater the number of veto points in government, the lower the likelihood that a state terminates its use of torture.     

China as a latecomer: Toward a global logic of the open policy

The paper reviews a number of substantive issue‐areas in China's foreign economic sector (the foreign trade system, industrial and geographical targeting, foreign investment regulations, and the foreign exchange regime), finding that conventional mercantilist accounts of China's recent success in world markets are overstated. In fact, the paper argues that the most salient changes occurring in China's foreign economic sector are now in many respects beyond the immediate control of the state. In this vein, it is argued that most scholars have seriously underestimated the structuring impact of the international political economy on China's reform and opening. Indeed, the paper maintains that there is a ‘global’ logic to the evolution of the Open Policy, just as others have identified an ‘economic’ or ‘political’ logic to foreign trade reform, the creation of the SEZs, liberalization of investment laws, the loosening of foreign exchange controls, and other such changes. The paper concludes, therefore, that there is much about the course of China's reform and deepening integration into the world economy that can be understood as a function of its position as a latecomer in the international system.     

Ethnicity and adjustment: A study of the self-image of Anglo-, Greek-, and Italian-Australian working class adolescents

Two measures of adjustment, the Erikson Psychosocial Stage Inventory and the Offer Self-Image Questionnaire, were administered to a sample of 450 working class Anglo-, Greek-, and Italian-Australian adolescents in years 9 and 11 of 9 Melbourne high schools. Anglo- and Greek-Australian adolescents scored similarly and significantly higher than Italian-Australians on a number of subscales, suggesting that culture conflict may be an influential factor in the adjustment of Italian-Australians, but not Greek-Australians. Significant differences between the minority groups, in favor of Greek-Australians, were interpreted as resulting from the relative differences in institutional support for and press toward assimilation of the two groups.
