Families of students with disabilities and those who are culturally and linguistically diverse (CLD), are looking for better educational opportunities. Charter schools offer promise as they were designed to promote student learning with limited control from the state. Charter schools though, have been criticized for relying on exclusionary discipline policies that affect CLD students and students with disabilities disproportionately. This study was designed to understand how Arizona charter schools use exclusionary discipline practices, with a focus on students with disabilities and CLD students. Two participants, a fourth grade and fifth grade teacher from a Phoenix metropolis charter school completed surveys and interviews where they answered questions about their classroom and their school’s discipline policies. Teachers were asked how they have adapted and administered classroom discipline policies and to what extent have positive behavioral strategies been implemented in an online setting due to the COVID-19 pandemic when schools transitioned to virtual learning. The results showed that in a virtual setting, teachers retained the practice of removing students from the “classroom”, expectations had to be modified to meet the needs of the new environment, and the school counselor served in conflicting roles. The findings suggested that charter schools and teachers may be transferring and adapting their reliance on exclusionary discipline practices even for an online setting with classrooms that have students with disabilities and those who are CLD.
The purpose of this project was to create a resource for parents to introduce them to the PBIS framework that is used in many schools across the country, and to three low-intensity positive behavior management strategies that can be utilized to prevent problem behaviors at school and home. The three strategies included in the resource are: behavior specific praise, precorrection, and high probability request sequences. All three of these strategies have been shown, through research, to help promote positive relationships between adults and children, and decreased problem behaviors when they are used in the classroom and school settings. Through a literature review that was conducted at the beginning of the project, it was found that there is very little research on the use of the three strategies by parents. This resource could potentially lead to more education and research being done on both the social validity of these strategies and their use in the home setting.

In the weeks following the first imported case of Ebola in the U. S. on September 29, 2014, coverage of the very limited outbreak dominated the news media, in a manner quite disproportionate to the actual threat to national public health; by the end of October, 2014, there were only four laboratory confirmed cases of Ebola in the entire nation. Public interest in these events was high, as reflected in the millions of Ebola-related Internet searches and tweets performed in the month following the first confirmed case. Use of trending Internet searches and tweets has been proposed in the past for real-time prediction of outbreaks (a field referred to as “digital epidemiology”), but accounting for the biases of public panic has been problematic. In the case of the limited U. S. Ebola outbreak, we know that the Ebola-related searches and tweets originating the U. S. during the outbreak were due only to public interest or panic, providing an unprecedented means to determine how these dynamics affect such data, and how news media may be driving these trends.
Methodology
We examine daily Ebola-related Internet search and Twitter data in the U. S. during the six week period ending Oct 31, 2014. TV news coverage data were obtained from the daily number of Ebola-related news videos appearing on two major news networks. We fit the parameters of a mathematical contagion model to the data to determine if the news coverage was a significant factor in the temporal patterns in Ebola-related Internet and Twitter data.
Conclusions
We find significant evidence of contagion, with each Ebola-related news video inspiring tens of thousands of Ebola-related tweets and Internet searches. Between 65% to 76% of the variance in all samples is described by the news media contagion model.
The reproductive ground plan hypothesis of social evolution suggests that reproductive controls of a solitary ancestor have been co-opted during social evolution, facilitating the division of labor among social insect workers. Despite substantial empirical support, the generality of this hypothesis is not universally accepted. Thus, we investigated the prediction of particular genes with pleiotropic effects on ovarian traits and social behavior in worker honey bees as a stringent test of the reproductive ground plan hypothesis. We complemented these tests with a comprehensive genome scan for additional quantitative trait loci (QTL) to gain a better understanding of the genetic architecture of the ovary size of honey bee workers, a morphological trait that is significant for understanding social insect caste evolution and general insect biology.
Results
Back-crossing hybrid European x Africanized honey bee queens to the Africanized parent colony generated two study populations with extraordinarily large worker ovaries. Despite the transgressive ovary phenotypes, several previously mapped QTL for social foraging behavior demonstrated ovary size effects, confirming the prediction of pleiotropic genetic effects on reproductive traits and social behavior. One major QTL for ovary size was detected in each backcross, along with several smaller effects and two QTL for ovary asymmetry. One of the main ovary size QTL coincided with a major QTL for ovary activation, explaining 3/4 of the phenotypic variance, although no simple positive correlation between ovary size and activation was observed.
Conclusions
Our results provide strong support for the reproductive ground plan hypothesis of evolution in study populations that are independent of the genetic stocks that originally led to the formulation of this hypothesis. As predicted, worker ovary size is genetically linked to multiple correlated traits of the complex division of labor in worker honey bees, known as the pollen hoarding syndrome. The genetic architecture of worker ovary size presumably consists of a combination of trait-specific loci and general regulators that affect the whole behavioral syndrome and may even play a role in caste determination. Several promising candidate genes in the QTL intervals await further study to clarify their potential role in social insect evolution and the regulation of insect fertility in general.
