When does the Gender Difference in Rumination Begin? Gender and Age Differences in the Use of Rumination by Adolescents

A cross-sectional non-clinical sample of 1,218 adolescents, aged 10–17 years, completed measures of stress, rumination, and depression to allow tests of the response style theory of S. Nolen-Hoeksema [J Res Adolesc 4:519–534, 1994] in adolescents, in particular whether increasing levels of stress and rumination in early adolescence are predictive of the onset of the gender difference in depression. Overall, females reported higher levels of stress, rumination, and depression than males. The onset of the gender differences in stress and depression occurred at age 13 years, and for rumination one year earlier at 12 years. Significantly, also from 13 years, rumination explained the gender difference in depression by showing that it significantly mediated the effect of gender on depression. Gender moderated the rumination to depression relationship; specifically the association was stronger for females than males. Developmental differences were noted in that rumination significantly mediated between stress and depression earlier in the age range for females than males. Results supported many of the predictions of Nolen-Hoeksema’s model of the emergence of a gender difference in adolescent depression.

ASEAN: Nucleus of Asia-Pacific Commnnity

I congratulate the Chinese Association for International Understanding for all it has been able to accomplish-during its 30 years of public diplomacy-in its mission to "Let the world understand China, and let China understand the world."     

西班牙的反恐立法：基于刑事法视角的考察

随着国际反恐公约的发展和恐怖主义活动的持续发生,西班牙的反恐立法发生了迅速变化.从刑事法视角来看,西班牙的反恐立法包括犯罪和刑罚,刑事程序、刑罚裁量和执行、青少年刑法、被害人待遇等内客.恐怖主义行为具有极其严重的社会危害性,但是,反恐斗争不能侵害公民的基本权利,而应在司法控制之下充分尊重合法性原则和比例原则.     

Socio‐economic Considerations in Biosafety and Biotechnology Decision Making: The Cartagena Protocol and National Biosafety Frameworks

Article 26.1 of the Cartagena Protocol on Biosafety left open the possibility for member countries to include in their biosafety regulatory processes the assessment of socio‐economic considerations. Countries may also decide to include such assessments as part of their national legislation or regulations for the approval and deliberate release into the environment of genetically engineered technologies. Countries are debating if and how to implement assessment of socio‐economic considerations. This paper contributes to the ongoing policy dialogue by discussing issues related to socio‐economic assessment including scope, timing, inclusion modalities, methods, decision‐making rules and standards, and the integration of socio‐economic assessments in biosafety and/or biotechnology approval processes. This paper also discusses the implications of such inclusion for technology flows and public and private sector R&D. If inclusion is not done properly, it may negatively impact technology flows especially from the public sector and render an unworkable biosafety system.     

Seasonal structure and dynamics of sarcosaprophagous fauna on pig carrion in a rural area of Cordoba (Argentina): their importance in forensic science

Four experiments, one in each season, were carried out during 2004 in a rural area of Córdoba, central Argentina. Two pigs (Sus scrofa L.), weighing approximately 8 kg each, were used in each of the four experiments. The animals were killed by a sharp blow to the head and immediately placed in an appropriate arthropod trap. One pig was placed in the shade and the other under direct sunlight. This research was conducted to determine the seasonal structure and dynamics of arthropods that constitute the sarcosaprophagous community in a given area of the central region of Argentina. The decomposition process was divided into five stages: fresh, bloated, decay, advanced decay and dry. The duration of each stage varied in different seasons, showing that the temperature and humidity are the most important variables that influence this process. A total of 51,500 adults and 36,909 immature were collected. More than 80% of the specimens collected belong to Insecta, and within this, Diptera were the most abundant order. The flies were mainly represented by adults and immature of the following species: Chrysomya albiceps (Wiedemann) (Calliphoridae), Musca domestica Linnaeus (Muscidae) and Fannia femoralis (Stein) (Fanniidae). Coleoptera were mainly represented by adults and immature of the species Creophilus maxillosus (Linnaeus) (Staphylinidae) and Dermestes maculatus (Geer) (Dermestidae). More than 50% of hymenopteran fauna collected belong to Formicidae. The trophic levels associated with the decomposition of the remains included five categories: necrophagous, parasites and predators of the necrophagous species, omnivores, opportunists and adventives. During faunal succession a strong dominance of the necrophagous species of the family Calliphoridae and Muscidae was observed, mainly during the early stages of decay process in all seasons.     

Permanent teeth development in a Spanish sample. Application to dental age estimation

The purpose of this study is to clarify the chronology of different stages of dental development, according to Demirjian, in a sample of Spanish children, which will enable us to build a database that will be used as a reference in regard to the dental development of individuals of our socio-geographic environment. In the same studied sample, a calculation of the dental age according to Demirjian was carried out. This study was conducted in a final sample consisting of 1010 orthopantograms, corresponding to Spanish children (485 boys and 525 girls) ages 2-16. Comparing the age of onset of the different stages among the children, evidence was found that girls had an earlier general development than boys. These differences were only statistically significant in teeth and concrete stages. The canine teeth revealed greater gender dimorphism, with significant differences in all stages compared with the upper canines. The method proposed by Demirjian for dental age calculation resulted in a significant overestimation of dental age in relation to the chronological age in boys (average of 0.87 years) and girls (average of 0.55 years). Data from this study may be used as reference for dental maturity, as well as a standard for estimating age in Spanish children.     

How is Anxiety Involved in the Longitudinal Relationship between Brooding Rumination and Depressive Symptoms in Adolescents?

A growing body of research supports the application of Response Styles Theory to adolescent populations. Although the essential dynamic, namely that rumination increases the incidence of depressive symptoms, has been demonstrated among adolescents, a number of important empirical questions remain, such as: what are the gender differences and developmental trends for brooding and reflective rumination?; does a reciprocal relationship exist between brooding or reflective rumination, on the one hand, and depressive symptoms and anxiety, on the other hand, over time? and how do additional variables (i.e., anxiety) impact upon the rumination-depressive symptoms relationship? In this study, self-reported levels of rumination (both brooding and reflective), and anxious and depressive symptoms were measured longitudinally across 4 months in a sample of 976 community adolescents (46 % females), aged 11–16 years old. Mean group differences showed that female adolescents reported engaging in more brooding rumination than male adolescents beginning at 13 years of age. A reciprocal brooding rumination to depressive symptoms relationship and a reciprocal brooding rumination to anxiety relationship were found over time, and they did not differ for boys and girls. We tested the possibility that anxious symptoms would function as a third variable, but the obtained model showed that brooding rumination and anxiety both contributed unique variance in predicting changes in depressive symptoms over time.
