A comparative analysis of school satisfaction and dropout risk of middle school students attending programs for students with emotional handicaps, severe emotional disturbance and general education students attending center schools and satellite schools

This study evaluated school satisfaction as an indicator of dropout risk of students with Emotional Handicaps (EH) and students with Severe Emotional Disturbance (SED). The students attended two different kinds of middle schools in a largely urban school district in South Florida. One hundred eight students in grade 8 (ages 13-16) participated in this study. Participants were administered the National Dropout Prevention Assessment (NDPA). Forty participants with EH and SED attended a special center school. Thirty-one participants with EH and SED attended satellite programs in a regular middle school. Thirty-seven general education participants attended the same regular middle school. Overall school satisfaction scores were generated, as well as three primary factors (school, environment and personal) and 16 subscales (school atmosphere, future income, difficulty level of classwork, teacher relationships, peer relationships, intrinsic interest in classwork, school hours, classwork stress, general attitude towards school, family influence, perceived opportunity for career, future goals, travel distance, leisure time, self-appraisal of performance, and self-esteem).^ Comparison of students with EH and SED revealed that both groups of students were rated at "low risk" of becoming dropouts on the Environmental factor and the Difficulty of Schoolwork subscale. Students with EH were rated at "caution risk" risk on the Travel Distance subscale. Students with SED were rated at "high risk" on this subscale.^ There were no significant differences in school satisfaction and dropout risk between different program delivery models. There were also no significant differences for category of students (EH, SED) by school type (center school, satellite program). All students were rated at "low risk" of dropping out of school.^ There were significant differences between general education students and students with EH and SED attending satellite programs. Students with EH and SED were rated at "caution risk" for dropping out on the Travel Distance and the Leisure Time subscales. Discussion of results, implications for practice and recommendations for further research are included. ^

A case study of a liberal Jewish day school's middle school transition

The Jacobson Sinai Academy is a Liberal Reform Jewish Day School, in North Miami Beach, Florida. When the Academy was started over 18 years ago it was designed as a K–6 school. This was in keeping with the existing model for Reform day schools at the time and met the needs and desires of the early founders. The philosophy of the school addressed meeting the needs of the individual child as well as the fostering of Judaic values and traditions in an academically nurturing and experiential setting. Upon graduation, students moved from the Academy to a variety of public and private options, all of which served the needs of the families at the time. In recent years, due to numerous factors within the community, parents voiced concerns as to where their children would continue their education during the critical middle school years. As a result of these concerns, and through the efforts of a dedicated group of parents and lay leaders, the decision was made to add an upper school component to the existing elementary configuration. This study is a qualitative case study which chronicles the organizational change effort that was undertaken for this purpose to determine facilitating conditions and impediments leading to the change. The analysis serves to inform others wishing to advance such an undertaking. ^ Results of the study indicated that certain conditions are necessary for the successful implementation of any change effort. The culture of the organization must be acknowledged and is a primary factor to be considered when advancing change. Collaboration with those committed to the enterprise must occur, and this in turn can lead to an agreed upon philosophy which expresses the diversity of needs and values of all of those involved. Resistance, while expected from certain individuals within the organization, can be overcome through the efforts of key players who assume leadership positions that are transformational in nature. Additionally, the rationale for middle schools, and the need for this one in particular, are factors which led to the success of this initiative. ^

Seagrass sediments as a global carbon sink: Isotopic constraints

Seagrass meadows are highly productive habitats found along many of the world's coastline, providing important services that support the overall functioning of the coastal zone. The organic carbon that accumulates in seagrass meadows is derived not only from seagrass production but from the trapping of other particles, as the seagrass canopies facilitate sedimentation and reduce resuspension. Here we provide a comprehensive synthesis of the available data to obtain a better understanding of the relative contribution of seagrass and other possible sources of organic matter that accumulate in the sediments of seagrass meadows. The data set includes 219 paired analyses of the carbon isotopic composition of seagrass leaves and sediments from 207 seagrass sites at 88 locations worldwide. Using a three source mixing model and literature values for putative sources, we calculate that the average proportional contribution of seagrass to the surface sediment organic carbon pool is ∼50%. When using the best available estimates of carbon burial rates in seagrass meadows, our data indicate that between 41 and 66 gC m−2 yr−1 originates from seagrass production. Using our global average for allochthonous carbon trapped in seagrass sediments together with a recent estimate of global average net community production, we estimate that carbon burial in seagrass meadows is between 48 and 112 Tg yr−1, showing that seagrass meadows are natural hot spots for carbon sequestration.
