Reducing Out-of-School Suspension in Title I Middle Schools: An Applied Study

Out-of-school suspension is a growing concern in the United States education system and affects students at the three Title I schools in the Central School System at a particularly high frequency. The purpose of this applied study was to solve the problem of high-frequency out-of-school suspension for three Title I middle schools in the Central School system and to formulate a solution to address the problem. A multi-method design was used, consisting of both qualitative and quantitative approaches. The first approach was structured interviews with two administrators from each school. The second approach was the analysis of archival data using the discipline data from the school system. The third approach was a teacher survey using a Likert scale to determine teacher perspectives on out-of-school suspension. These tools were used to develop a focused program that will allow the schools to meet student needs while also maintaining safety, order, and a positive school climate. The results of the data showed that administrators and teachers were aware of the negative implications of out-of-school suspension but were experiencing tension between the need to maintain discipline within the school and teacher support while also desiring to reduce out-of-school suspension. The data showed that administrators identified significant differences in most of the student body and students who have frequent behavioral concerns and multiple suspensions. An alternative to suspension program was developed and proposed as a solution to reduce out-of-school suspension

Fire as a fundamental ecological process: Research advances and frontiers

© 2020 The Authors.Fire is a powerful ecological and evolutionary force that regulates organismal traits, population sizes, species interactions, community composition, carbon and nutrient cycling and ecosystem function. It also presents a rapidly growing societal challenge, due to both increasingly destructive wildfires and fire exclusion in fire‐dependent ecosystems. As an ecological process, fire integrates complex feedbacks among biological, social and geophysical processes, requiring coordination across several fields and scales of study. Here, we describe the diversity of ways in which fire operates as a fundamental ecological and evolutionary process on Earth. We explore research priorities in six categories of fire ecology: (a) characteristics of fire regimes, (b) changing fire regimes, (c) fire effects on above‐ground ecology, (d) fire effects on below‐ground ecology, (e) fire behaviour and (f) fire ecology modelling. We identify three emergent themes: the need to study fire across temporal scales, to assess the mechanisms underlying a variety of ecological feedbacks involving fire and to improve representation of fire in a range of modelling contexts. Synthesis: As fire regimes and our relationships with fire continue to change, prioritizing these research areas will facilitate understanding of the ecological causes and consequences of future fires and rethinking fire management alternatives.Support was provided by NSF‐DEB‐1743681 to K.K.M. and A.J.T.

Consensus Paper:Cerebellar Development

International audienceThe development of the mammalian cerebellum is orchestrated by both cell-autonomous programs and inductive environmental influences. Here, we describe the main processes of cerebellar ontogenesis, highlighting the neurogenic strategies used by developing progenitors, the genetic programs involved in cell fate specification, the progressive changes of structural organization, and some of the better-known abnormalities associated with developmental disorders of the cerebellum

The prenatal origins of cancer

The concept that some childhood malignancies arise from postnatally persistent embryonal cells has a long history. Recent research has strengthened the links between driver mutations and embryonal and early postnatal development. This evidence, coupled with much greater detail on the cell of origin and the initial steps in embryonal cancer initiation, has identified important therapeutic targets and provided renewed interest in strategies for the early detection and prevention of childhood cancer. © 2014 Macmillan Publishers Limited.
