Language disorders in disruptive behavior disordered homicidal youth.

Eight homicidal youths were assessed for language disorders and psychiatric diagnoses using a battery of standardized language tests and the Diagnostic Interview for Children and Adolescents. Both language disorders and Diagnostic and Statistical Manual III-R psychiatric diagnoses were present in all subjects.     

The logic of ‘Policy’ and successful policies

Developed on the premise that how we conceive of ‘policy’ and ‘successful policy’ guides policy sciences' research and evaluation, this paper responds to the conceptual questions of “what is a policy?” and “when is a policy successful?” Formal or logical conditions are established to distinguish ‘policy’ from related concepts. The notion ‘relevant public’ is introduced to distinguish public policies from private policies and to identify fairly-declared policies. Further, conditions are developed that can be used as logical tests for three types of policy success: implementation success, instrumental success and success in normative justification.     

Institutional Change and Ethnic Parties in South America

The central question of this article is why indigenous social movements formed electorally viable political parties in Latin America in the 1990s. This development represents a new phenomenon in Latin America, where ethnic parties have been both rare and unpopular among voters. Institutional reforms in six South American countries are examined to see if the creation and success of these parties can be correlated with changes in electoral systems, political party registration requirements, or the administrative structure of the state. The study concludes that institutional change is likely to be a necessary but not sufficient condition for the emergence and electoral viability of ethnic parties.     

China's consumer revolution: The 1990s and beyond

Since 1980 China's economic revolution has enabled more households to allocate labor to market‐related activities to earn more income. In 1992 an even greater surge in market economy growth took place when urban households began abandoning state‐related occupations and took their chances in the marketplace. The increase in consumer spending that followed reflects a new pattern of household spending for the first time in China since 1949: the share of spending for food relative to spending for other categories of goods and services is fast declining. This new trend, already strongly evident among high income‐earning households, is rapidly being replicated by other households as their incomes rise. During the 1990s new consumer patterns have emerged in the cities of the coastal provinces that strongly indicate that a consumer revolution is under way. This revolution has revived traditional gift‐giving between the Chinese people, thus facilitating the strengthening of their social, economic, and political ties and encouraging people to emphasize social and political stability.     

The Allen priority/consequence model as a behavioral approach to reduction of high risk behavior in youth

Youth violence in America has grown to insurmountable levels. Homicide is now the third leading cause of death for youth ages 5–14, the second leading cause of death for those ages 15–24 and the number one cause of death among black males ages 15–34. With increased levels of violence and senseless killings across the nation, there is a need to explore behavioral and environmental causes of high risk behavior and various types of interventions to decrease antisocial behavior. Violence prevention should be approached comprehensively from a myriad of approaches and levels of prevention and intervention that should infiltrate individuals, homes, schools, communities and systems.

Numerous types of theories are being designed, implemented and evaluated to decrease and prevent unhealthy behaviors. While there is a need to continue to refine intervention and containment strategies, a preventative approach to addressing root causes of antisocial behaviors needs to be considered as we comprehensively look at interventions for violence prevention. The purpose of this article is to add to the body of research a theory, the Priority/ Consequence model, which depicts interrelated dynamic behavioral and societal variables that can influence, positively or negatively, attitudes, values and beliefs that establish prioritized behaviors that produce consequences.     

Collusion in auctions for emission permits: An experimental analysis

Environmental markets have several institutional features that provide a new context for the use of auctions and that have not been studied previously. This paper reports on laboratory experiments testing three auction forms—uniform and discriminatory price sealed‐bid auctions and an ascending clock auction. We test the ability of subjects to tacitly or explicitly collude in order to maximize profits. Our main result is that the discriminatory and uniform price auctions produce greater revenues than the clock auction, both with and without explicit communication. The clock appears to facilitate successful collusion, both because of its sequential structure and because it allows bidders to focus on one dimension of cooperation (quantity) rather than two (price and quantity).© 2009 by the Association for Public Policy Analysis and Management.
