Children with Incarcerated Parents: What Services are Available for Children with a Parent Releasing from Prison?

Children with incarcerated parents are a growing “at risk” population in the United States. Upon parental release, many children will be reunited or have some form of contact with their parent. Currently, there is limited programming available for this population, specifically during the reunification process. The Reconnections Group\u27s aim is to provide children and youth age appropriate education and support during their parent’s transition back into the community. The mission of the Reconnections Group is to provide a supportive, encouraging, and positive atmosphere for children and youth with a parent releasing or recently released from prison, while fostering a positive parent child relationship and promoting current and future pro-social behaviors in children and youth

The Relationship Between Teachers\u27 Perceptions of the Feedback They Receive and Their Teaching Efficacy in High-Performing Schools

As reform efforts are prescribed in every state through mandates and regulations in an effort to better prepare students to compete in a global economy, and as states like Indiana implement new evaluation plans for teachers based on a rigorous rubric and objective measures of student achievement, close attention to the ripple effects must be involved. While efforts such as professional learning communities and instructional coaches are aimed at building teacher capacity, maximum results can only be achieved when school leaders balance how they leverage their evaluative power while promoting these formative experiences. Absent in the drive for heightened accountability, evaluative feedback, and formative feedback is the understanding of the effect that specific characteristics of feedback will have on teacher self-efficacy. The purpose of this study was to extend previous research regarding teachers\u27 perceptions of the characteristics of the feedback they receive in six high-performing elementary schools in Indiana, rich with evaluative and formative feedback. In addition to the feedback characteristics, teacher demographic variables were included in the data collection and analysis. Hierarchical multiple regression was used to best determine the predictive power of the independent variables on teacher self-efficacy. The schools in the study employed an evaluative model which called for frequent observations and frequent feedback using a state-mandated, uniform, rigorous evaluation rubric. In addition, each school had daily collaboration time and a full-time literacy coach, providing for ample formative feedback opportunities. For the formative feedback model, regression showed that the independent variables did not have a significant predictive relationship to any of the subscales for teacher efficacy. For the evaluative feedback model, regression showed that the independent variables did have a significant predictive relationship to teacher self-efficacy for Instructional Strategies and Classroom Management and did not for Student Engagement. For the total feedback model, regression showed that the independent variables did have a significant predictive relationship to teacher self-efficacy for Classroom Management and did not for Instructional Strategies and Student Engagement. Finally, an examination of the data from the open-ended questions of the survey showed teachers with differing levels of self-efficacy perceived useful and helpful feedback differently. Building the capacity of teachers is complex; nonetheless, when high-performing schools seek to be better today than they were yesterday, all protocols must be examined for best practice. Thus, schools that offer rich formative feedback experiences must deliver evaluative feedback that embodies emotional intelligence and respects relationships, principals and instructional coaches must be aligned, and attention to differentiation in leadership must be paid when planning for all types of feedback

Chemical ionization tandem mass spectrometer for the in situ measurement of methyl hydrogen peroxide

A new approach for measuring gas-phase methyl hydrogen peroxide [(MHP) CH_3OOH] utilizing chemical ionization mass spectrometry is presented. Tandem mass spectrometry is used to avoid mass interferences that hindered previous attempts to measure atmospheric CH_3OOH with CF_3O− clustering chemistry. CH_3OOH has been successfully measured in situ using this technique during both airborne and ground-based campaigns. The accuracy and precision for the MHP measurement are a function of water vapor mixing ratio. Typical precision at 500 pptv MHP and 100 ppmv H_2O is ±80 pptv (2 sigma) for a 1 s integration period. The accuracy at 100 ppmv H_2O is estimated to be better than ±40%. Chemical ionization tandem mass spectrometry shows considerable promise for the determination of in situ atmospheric trace gas mixing ratios where isobaric compounds or mass interferences impede accurate measurements

Imine Azaenolates: Synthesis, Reactivity, and Outlook

Azaenolates are, quite simply, the aza variant of enolates. Compared to their oxygen counterparts, additional control of the reactivity of azaenolates can be achieved by altering the substituent on the nitrogen atom as well as the metal counterion. Since the seminal examples reported in the early 1960s, azaenolates of various metals have been shown to react with a diverse set of electrophilic partners, including challenging electrophiles such as alkyl fluorides, epoxides, and oxetanes. This review describes in detail the current state of the art of the chemistry of azaenolates derived from imines, with a particular focus on the comparison of the reactivity exhibited with different metal counterions

In Conversation with the Ancestors: Indigenizing Archaeological Narratives at Acadia National Park, Maine

In North America, Indigenous pasts are publicly understood through narratives constructed by archaeologists who bring Western ideologies to bear on their inquiries. The resulting Eurocentric presentations of Indigenous pasts shape public perceptions of Indigenous peoples and influence Indigenous perceptions of self and of archaeology. In this paper we confront Eurocentric narratives of Indigenous pasts, specifically Wabanaki pasts, by centering an archaeological story on relationality between contemporary and past Indigenous peoples. We focus on legacy archaeological collections and eroding heritage sites in Acadia National Park, Maine. We present the “Red Paint People” myth as an example of how Indigenous pasts become distorted through archaeological narratives influenced by Western ideologies and offer a framework for indigenizing archaeological narratives constructed previously through Western lenses, using Indigenous language and community engagement to carry out the study

Performance analysis integration in the Uintah software development cycle

ManuscriptThe increasing complexity of high-performance computing environments and programming methodologies presents challenges for empirical performance evaluation. Evolving parallel and distributed systems require performance technology that can be flexibly configured to observe different events and associated performance data of interest. It must also be possible to integrate performance evaluation techniques with the programming paradigms and software engineering methods. This is particularly important for tracking performance on parallel software projects involving many code teams over many stages of development. This paper describes the integration of the TAU and XPARE tools in the Uintah Computational Framework (UCF). Discussed is the use of performance mapping techniques to associate low-level performance data to higher levels of abstraction in UCF and the use of performance regression testing to provides a historical portfolio of the evolution of application performance. A scalability study shows the benefits of integrating performance technology in building large-scale parallel applications

The contribution of constitutional supercooling to nucleation and grain formation

The concept of constitutional supercooling (CS) including the term itself was first described and discussed qualitatively by Rutter and Chalmers in order to understand the formation of cellular structures during the solidification of tin, and then quantified by Tiller et al. On that basis, Winegard and Chalmers further considered 'supercooling and dendritic freezing of alloys' where they described how CS promotes the heterogeneous nucleation of new crystals and the formation of an equiaxed zone. Since then the importance of CS in promoting the formation of equiaxed microstructures in both grain refined and unrefined alloys has been clearly revealed and quantified. This paper describes our current understanding of the role of CS in promoting nucleation and grain formation. It also highlights that CS, on the one hand, develops a nucleation-free zone surrounding each nucleated and growing grain and, on the other hand, protects this grain from readily remelting when temperature fluctuations occur due to convection. Further, due to the importance of the diffusion field that generates CS, recent analytical models are evaluated and compared with a numerical model. A comprehensive description of the mechanisms affecting nucleation and grain formation and the prediction of grain size is presented with reference to the influence of the casting conditions applied during the practical casting of an alloy
