The Tier 1 Program of the Project P.A.T.H.S. (Positive Adolescent Training through Holistic Social Programmes) is a curricular-based program that attempts to promote positive youth development in Hong Kong. In the second year of the Full Implementation Phase, 20 experimental schools (n = 2,784 students) and 23 control schools (n = 3,401 students) participated in a randomized group trial. Analyses based on linear mixed models via SPSS showed that participants in the experimental schools displayed better positive youth development than did participants in the control schools based on different indicators derived from the Chinese Positive Youth Development Scale. Differences between experimental and control participants were also found when students who joined the Tier 1 Program and perceived the program to be beneficial were employed as participants of the experimental schools.

AbstractThe abundance of the larvae of Phyllobius piri L. and P. viridicollis F. (Col. Curculionidae) was investigated in an abandoned field in central Sweden. On the basis of the individual growth curve and the life table of the larvae the production of P. piri was calculated to be 4.6 ± I.9 g dw per m2 or 25 ± II kcal per m2 (mean ± 95 per cent c.i.). The population of the hibernating pupae of P. piri was about 500 per m2 during three successive years. During the same period the abundance of hibernating larvae of P. viridicollis was I00-250 per m2. Notes are given on the life history of the two species. The larvae are described by B. Lekander in an appendix.

Data Analytic

Longitudinal panel data examples are used to illustrate estimation methods for individual growth curve models. These examples constitute one of the basic multilevel analysis settings, and they are used to illustrate issues and concerns in the application of hierarchical modeling estimation methods, specifically, the widely advertised HLM procedures of Bryk and Raudenbush. One main expository purpose is to demystify these analyses by showing equivalences with simpler approaches. Perhaps more importantly, these equivalences indicate useful data analytic checks and diagnostics to supplement the multilevel estimation procedures. In addition, we recommend the general use of standardized canonical examples for the checking and exposition of the various multilevel procedures; as part of this effort, methods for the construction of longitudinal data examples with known structure are described.
