Reciprocal Relationships between Teacher Ratings of Internalizing and Externalizing Behaviors in Adolescents with Different Levels of Cognitive Abilities

Are internalizing and externalizing behavior problems interrelated via mutually reinforcing relationships (with each behavior leading to increases over time in levels of the other behavior) or mutually suppressing relationships (with each behavior leading to decreases over time in levels of the other behavior)? Past research on the directionality of these relationships has led to ambiguous results, particularly in adolescence. Furthermore, the extent to which prior results will generalize to adolescents with low levels of cognitive abilities remains unknown. This second limit is particularly important, given that these adolescents are known to present higher levels of externalizing and internalizing behaviors than their peers with average-to-high levels of cognitive abilities, and that the mechanisms involved in the reciprocal relationships between these two types of behaviors may differ across both populations. This study examines the directionality of the longitudinal relationships between externalizing and internalizing behavior problems as rated by teachers across three measurement waves (corresponding to Grades 8–10) in matched samples of 138 adolescents (34.78?% girls) with low levels of cognitive abilities and 556 adolescents (44.88?% girls) with average-to-high levels of cognitive abilities. The results showed that the measurement structure was fully equivalent across time periods and groups of adolescents, revealing high levels of developmental stability in both types of problems, and moderately high levels of cross-sectional associations. Levels of both internalizing and externalizing behaviors were higher among adolescents with low levels of cognitive abilities relative to those with average-to-high levels of cognitive abilities. Finally, the predictive analyses revealed negative reciprocal longitudinal relationships (i.e., mutually suppressing relationships) between externalizing and internalizing problems, a result that was replicated within samples of adolescents with low, and average-to-high levels of cognitive ability.     

Rent seeking and the welfare cost of trade barriers

This paper estimates the potential social cost of trade barriers using the Harberger and the Tullock/Posner approaches for a sample of U.S. food and tobacco manufacturing industries. In addition, it tests the relationship between the computed welfare losses and special-interest political activity (PAC contributions). If all rents were dissipated through rent seeking, the social cost of trade barriers would be about 12.5 percent of domestic consumption and would be particularly large for sugar and milk products where quotas are the main instrument of protection. Furthermore, the results indicate that welfare losses are positively associated with industry lobbying but the strength of such association is strongly dependent on industry concentration.     

Resolving problems in the current international monetary system

The current international monetary system, characterized by floating rates among major currencies and by the US dollar's de facto role as the most important asset and transaction currency, exhibits several problems, says Nobuyuki Ichikawa of the Bank of Japan and a senior research fellow at IIPS. Under this system, resolving current account imbalances is difficult and exchange rates tend to fluctuate widely, harming economies, says Ichikawa. The dollar's de facto role, he argues, spares the US the incentive to coordinate its policies. He proposes that the yen and the mark supplement the dollar's role and analyzes the policies that Japan must adopt to achieve an ideal monetary system.     

Does intellectual property lead to economic growth? Insights from a novel IP dataset

While policymakers often make bold claims as to the positive impact of intellectual property (IP) rights on both developed and developing country economies, the empirical literature is more ambiguous. IP rights have both incentive and inhibitory effects that are difficult to isolate in the abstract and are dependent on economic context. To unravel these contradictory effects, this article introduces an index that evaluates the strength of IP protection in 124 developing countries for the years 1995 to 2011. We illustrate the value of this index to economics study and show evidence that is consistent with IP leading to increased growth. Our results are further consistent with two causal pathways highlighted in the literature: that IP leads to greater levels of technology transfer and increased domestic inventive activity. Yet other aspects of our study fit uneasily with this simple story. For example, we find evidence suggesting that increased levels of growth lead to greater levels of IP protection, contradictory evidence in the literature linking IP with growth, a lack of evidence that increased levels of IP protection lead to actual use of the IP system, and problems with what IP indexes measure. Because of this, we suggest another – and so far undertheorized – explanation of the links between IP and growth: that IP may have few direct effects on growth and that any causality is a result of belief rather than actual deployment of IP.     

Comparison of two methods for isolating DNA from human skeletal remains for STR analysis

Abstract: The quality and efficiency of a standard organic DNA isolation method and a silica‐based method using the QIAGEN Blood Maxi Kit were compared to obtain human DNA and short tandem repeats (STRs) profiles from 39 exhumed bone samples for paternity testing. DNA samples were quantified by real‐time PCR, and STR profiles were obtained using the AmpFlSTR^® Identifiler^® PCR amplification kit. Overall, the silica‐based method recovered less DNA ranging from 0 to 147.7 ng/g (average 7.57 ng/g, median = 1.3 ng/g) than did the organic method ranging from 0 to 605 ng/g (average 44.27 ng/g, median = 5.8 ng/g). Complete profiles (16/16 loci tested) were obtained from 37/39 samples (95%) using the organic method and from 9/39 samples (23%) with the silica‐based method. Compared with a standard organic DNA isolation method, our results indicate that the published silica‐based method does not improve neither the quality nor the quantity of DNA for STR profiling.     

About the Impossibility of Absolute State Sovereignty

State sovereignty is often thought to be absolute, unlimited. This paper argues that there is no such a thing as absolute State sovereignty. Indeed, absolute sovereignty is impossible because all sovereignty is necessarily underpinned by its conditions of possibility—i.e. limited sovereignty is the norm, though the nature of the limitations varies. The article consists of two main sections: (a) the concept of sovereignty: this section is focused on some of the limitations the concept of sovereignty itself presents; and (b) a historical account of the notion of sovereignty as it was used in the Ancient Times. The particular focus on early notions of a modern concept such as sovereignty has to do with the fact that this early notion has been anthropomorphised with societal evolution. Therein, the current concept of State sovereignty embraces the same limitations it had in its ancient form as a non-fully developed conceptual idea. The implications of understanding State sovereignty as limited rather than absolute are several, both directly and indirectly. A main immediate consequence is that sovereign States can cooperate together, limit their sovereignty and still be considered sovereign.     

The Crimes of the Last Dictatorship in Argentina and its Qualification as Genocide: A Historicization

The last military dictatorship in Argentina was characterized by gross and systematic human rights violations. After the restoration of democracy in 1983, President Raúl Alfonsín put the military juntas on trial. Criminal prosecution of the abuses was later halted through laws and decrees. In 2003, under the Néstor Kirchner administration, the trials were resumed and some of the sentences incorporated the idea that the crimes had been committed in the framework of genocide. This article reconstructs the history of the uses and re-significations, furthered by local and transnational actors, of the category of genocide and the ways in which it was incorporated to characterize the crimes committed by the Argentine dictatorship. I argue that the use of this category shows the long presence of the Shoah paradigm in the country and the adoption of the international framework of human rights by actors involved in pro-accountability and memorialization processes.     

The gendered construction of expert discourse: An analysis of psychiatric evaluations in criminal court

According to critical literature, psychiatrization is a central feature of gendered social control. It operates in a twofold process: by orienting women to medical institutions rather than the penal system, and, for those women who do enter the criminal justice system, by favoring an interpretation of their behavior in terms of mental health problems. However, the production of gendered social control cannot be reduced to institutional decision-making; it also leaves its traces in various discursive forms. One such form is forensic psychiatrists' discourse on the offenders they evaluate. Our study analyzes these forensic reports as units of a computerized database. Our goal is to gain insight into the text by means of systematic quantitative and qualitative procedures. Even though the expert discourse is shaped by specifications requested by the court, the discourse examined here constructs two very distinct identities that do not correspond to stereotyped conceptions about femininity and masculinity.
