\"Morfodinâmica de um segmento da praia da Ilha Comprida, litoral sul do Estado de São Paulo\" / Morphodynamic of Ilha Comprida beach segment, southern coast of the state of São PauloMarquez, Mainara da Rocha Karniol 25 June 2007 (has links)
A dinâmica de praia constitui conhecimento elementar em obras de engenharia e na compreensão da evolução costeira ao longo do Quaternário recente. Buscou-se avaliar a variação temporal de curto período da morfologia e do volume de sedimento em um segmento na porção sul da praia da Ilha Comprida, litoral sul de São Paulo. Os resultados permitiram algumas interpretações, tanto em escala diária, como sazonal. As morfologias e os volumes do trecho estudado apresentaram maior similaridade entre as campanhas de maio de 2005 e janeiro de 2006, com estágio morfodinâmico de praia dissipativa, e entre agosto e novembro de 2005, com estágio de praia intermediária do tipo banco e calha. As ondas de sul com alturas de até 1 m e período médio entre 7 e 8 s atuaram no processo de engordamento da praia emersa, enquanto que as ondas desta mesma direção com alturas a partir de 1,5 m e período médio entre 8 e 10 s exerceram papel erosivo. De forma inversa, as ondas de leste com até 1 m de altura e período médio entre 6 e 8 s exerceram papel erosivo e com até 1,5 m e período médio entre 6 e 7 s, papel deposicional. / The knowledge of beach dynamics is fundamental in any coastal engineering projects as well as in the coastal evolution comprehension during the Late Quaternary. The aim of this study is to evaluate the short-term variations in morphology and sediment volume in a beach segment located in the southern portion of the Ilha Comprida, southern coast of the state of São Paulo, Brazil. The results allowed us to get important conclusions on daily and seasonal variations in beach morphology and behaviour. The morphology and volume data show similarity between may/2005 and jan/2006, with dissipative morphodynamic state characteristics, as well as between aug/2005 and nov/2005, characterized by an intermediate morphodynamic state. Southerly waves reaching 1m high and mean period between 7 and 8 s acts on the emerged part of the segment in a depositional way as well as southerly waves higher than 1,5 m and period between 8 and 10 s cause erosion in the same part of the beach profile. Easterly waves act in an opposite way, with lower heights causing erosion and higher causing deposition.

Long-term Evaluation of a Primary Level Intervention in a Rurally-located Middle School and Elementary SchoolBlevins, Leia D., Fox, James J., Herald, C., Booher, T., Edwards, S. 01 March 2015 (has links)
This study reports long-term evaluation of school-wide positive behavior support (SWPBS) in a rurally-located K – 8 and a middle school. With assistance from a university-based PBS project, these schools developed and implemented a SWPBS program. Target positive behaviors (respect, responsibility, cooperation) were operationally defined and directly taught to students. A reward ticket system was used to reinforce students’ positive behaviors. Office discipline referrals (ODRs) and reward tickets were recorded. At the end of each grading period, students with at least 1 ticket attended a school-wide celebration. An A-B case study design analyzed results for five-years for the K-8 and four years for the middle school. Following the first year of SWPBS, ODR rates decreased substantially, correlating moderately with reinforcement tickets given. Compared to two similar schools without SWPBS in the same district, the K-8 school’s had substantially fewer overall ODRs and fewer students with high-risk levels of referrals. ODR reductions resulted in recovering an average 5.25 and 10 student class hours and 11.75 and 25 administrative hours in the elementary and middle schools, respectively. These results replicated and extended effects reported by others. Issues regarding consistent SWPBS implementation and measurement of its effects as well as future research are addressed.
