The purpose of this study was to examine in a sample of 11,516 secondary school students the extent to which different behavioral, emotional and cognitive problems (a) reflected one or more underlying common factors; (b) actually cooccurred; and (c) were single problems. Principal Component Analyses were performed and percentagewise techniques were used. PCA demonstrated that one or more general syndromes could not by far account for all of the variance of the variables. The results suggest the existence of adolescent subgroups with divergent comorbidity patterns: those who primarily report one single symptom; those who report concurrent symptoms either exclusively in the category of behavioral problems or exclusively in the category of emotional and cognitive problems; and those who report concurrent symptoms in both categories. This distinction between different subgroups has important theoretical, diagnostic, and treatment implications. 相似文献

This article presents empirical findings regarding the relationship between decentralisation of provision of water supply and corruption in provision of services. The current policy advice from the international agencies of aiming for decentralisation as an end in itself is questioned. The conventional wisdom that decentralisation brings management closer to the service recipients and is therefore likely to reduce corruption is also disputed. Drawing on a large database from two large Indian states of Madhya Pradesh and Chhattisgarh, the interaction between various actors is analysed. We find that the level of corruption in water supply agencies run by local governments is higher than that in the agencies run by the regional government.

- Shareholder rights have been the centre of the debatein Corporate Governance since recently. At the same time, modernsecurities markets have evolved and changed profoundly in recentdecades, both in the way in which the securities are representedand transferred—through electronic book entries held byintermediaries—and in the geographical reach of such transfers:every corner of the world.
- Recent research has thoroughly analysedthe effects of the indirect holding system in those countriesthat have chosen to give legal status to indirect holding systems(where the paradigm is the USA), leading to the conclusion thatin these countries the issuer–investor relationship encountersfar more difficulties than in those that facilitate direct holding.Some scholars have even proposed that countries such as theUSA should move into a direct holding similar to the Spanishone.
