Writing a wrong: Coupled RNA polymerase II transcription and RNA quality control

Processing and maturation of precursor RNA species is coupled to RNA polymerase II transcription. Co-transcriptional RNA processing helps to ensure efficient and proper capping, splicing, and 3' end processing of different RNA species to help ensure quality control of the transcriptome. Many improperly processed transcripts are not exported from the nucleus, are restricted to the site of transcription, and are in some cases degraded, which helps to limit any possibility of aberrant RNA causing harm to cellular health. These critical quality control pathways are regulated by the highly dynamic protein-protein interaction network at the site of transcription. Recent work has further revealed the extent to which the processes of transcription and RNA processing and quality control are integrated, and how critically their coupling relies upon the dynamic protein interactions that take place co-transcriptionally. This review focuses specifically on the intricate balance between 3' end processing and RNA decay during transcription termination.

A Model for Hospital Discharge Preparation: From Case Management to Care Transition

There has been a proliferation of initiatives to improve discharge processes and outcomes for the transition from hospital to home and community-based care. Operationalization of these processes has varied widely as hospitals have customized discharge care into innovative roles and functions. This article presents a model for conceptualizing the components of hospital discharge preparation to ensure attention to the full range of processes needed for a comprehensive strategy for hospital discharge

A longitudinal investigation of maternal influences on the development of child hostile attributions and aggression

Aggression in children is associated with an enhanced tendency to attribute hostile intentions to others. However, limited information is available regarding the factors that contribute to the development of such hostile attribution tendencies. We examined factors that contribute to individual differences in child hostile attributions and aggression, focusing on potential pathways from maternal hostile attributions via negative parenting behavior. We conducted a longitudinal study of 98 mothers and children (47 male, 51 female), recruited from groups experiencing high and low levels of psychosocial adversity. Maternal hostile attributions, observed parenting, and child behaviour were assessed at 18 months and 5 years child age, and child hostile attributions were also examined at 5 years. Independent assessments of maternal and child processes were utilized where possible. Analyses provided support for a direct influence of maternal hostile attributions on the development of child hostile attributions and aggressive behaviour. Maternal hostile attributions were also associated with negative parenting behaviour, which in turn influenced child adjustment. Even taking account of possible parenting influences and preexisting child difficulties, hostile attributions in the mother showed a direct link with child aggression at 5 years. Maternal hostile attributions were themselves related to psychosocial adversity. We conclude that maternal hostile attributions are prevalent in high-risk samples and are related to less optimal parenting behaviour, child hostile attributions, and child aggression. Targeting hostile maternal cognitions may be a useful adjunct to parenting program

How Grain Size Corresponds With Human Habitation

Humans have reacted to changes in their environment for millennia. Consequently, humans have modified their environment for just as long. This study sought to see if humans inhabited South Inlet Park in Boca Raton, FL because of improved environmental conditions, which would cause a natural change in grain size, or if the grain size shifted because humans inhabited the area. Two locations were picked at South Inlet Park for archaeological excavation. Sediment samples were collected during the excavation from different levels of the test units. Each individual sample was weighed when wet to measure the moisture concentration because this affects how the artifacts are preserved. Then, the samples were dried overnight and weighed again before sieving. Sieving separates the sediment by grain size, which allows for the weight to be categorized by the size of the sediment. The data was then recorded and analyzed to see if there was any correlation between human inhabitation and grain size. Preliminary data shows that grain size was smaller in the levels where human artifacts were found, indicating there was a shift in the grain size during times of human habitation

How Humans Have Affected the Charcoal Content of Sediment in a Barrier Island Environment in Boca Raton, FL

Geoarchaeology is the collaboration of geology and archaeology to better understand archaeological sites and explain why or how processes are occurring. Geoarchaeology allows for scientific explanations into exploring what existed before, during and after human dwelling. One component of geoarchaeological testing is charcoal analysis. Learning about the fire history of an area is an important feature to investigating what life was like before the modern era. The goal for this study was to gain further data and knowledge on the human impacts to barrier island environments, with specific interest in South Florida. We hypothesized that humans moved into the barrier islands in Boca Raton because they became developed and stable enough for human habitation but in doing so, the sediment experienced an increase in carbon content, specifically charcoal concentrations. To test this hypothesis sediment samples were collected during an archaeological excavation of two sites at South Inlet Park. The samples were tested for microscopic charcoal concentrations. Preliminary results indicate that charcoal concentrations increased in layers where human habitation was identified by artifact collections. Nonetheless, over time, the environment returned to its natural state, before human interaction

Gettysburg College Sustainability Proposal

In the fall of 2011, the Environmental Studies capstone class led by Professor Rutherford Platt was asked to write Gettysburg College’s first Sustainability Plan. The goal of the plan was to develop specific sustainable practices for the campus that were related to the three pillars of sustainability: economic, social, and environmental, and how integrating diligent sustainable practices into each of these respected pillars will result in a more conscious campus, community, and future. In 2010, Gettysburg College turned to the Sustainability Tracking Assessment and Rating System (STARS) to quantify the institution’s sustainability efforts, providing a self-check mechanism to encourage sustainability applications to all aspects of the College. The American College and University Presidents’ Climate Commitment was signed in 2007 by former Gettysburg College President Katherine Haley Will, declaring that Gettysburg College would become carbon neutral by 2032. Gettysburg College has made large strides in the search for sustainability, and aims to continue its dedication to furthering sustainable practice. The following plan outlines the six priority areas identified by the Capstone class: progress of the American College and University Presidents’ Climate Commitment, Dining Services, campus green space, community outreach, integration of sustainability into the Gettysburg College Curriculum, and the Sustainability Advisory Committee. The first priority area identified was monitoring and upholding the American College and University Presidents’ Climate Commitment (ACUPCC). Though creating new sustainability initiatives on campus is the driving force towards an increasingly sustainable college and community, it is imperative that these goals be carried out in full to maximize beneficial returns. In order to reach carbon neutrality, Gettysburg College hopes to increase energy efficiency in buildings, incorporate renewable energy sources on campus, and mitigate remaining emissions through the purchase of carbon offsets. To further the College’s progress, it is proposed that Gettysburg College continue its energy-efficient appliance purchasing policy, as well as create a policy to offset all greenhouse gas emissions generated by air travel for students study abroad. As stated by the ACUPCC, a Sustainability Committee should take responsibility for the updates and progress reports required to meet the goal of carbon neutrality. The second priority area identified was sustainability in Dining Services. Gettysburg College is home to 2,600 students, all of whom require three full meals a day. Dining Services accounts for a large fraction of Gettysburg College’s sustainability efforts, already implementing sustainability through composting, buying local produce, and using biodegradable products. The proposed on-campus sales cuts of non-reusable to-go items, a change in campus mentality on food waste, and improved composting practices will translate to an increasingly sustainable campus, as well as a well-fed campus body. The third priority was maintaining green space on campus. Ranked as the 23rd most beautiful campus in the United States by The Best Colleges, Gettysburg College utilizes campus green space to create an atmosphere that is conducive to activity as well as tranquility. The plan proposes that Gettysburg College and its grounds facilities continue their exceptional efforts, focusing on increasing the use of the student garden, creating a new rain garden or social area on campus, and converting unnecessary parking lots into green space. As these additions are completed, they must be introduced to the student body and faculty alike to assure these areas are known and utilized. The fourth priority was utilizing community outreach to spread awareness of sustainability initiatives on and off campus. To connect the sustainability-geared changes proposed in this plan, community outreach at Gettysburg College is assessed to estimate how well these initiatives are communicated and promoted to both potential and enrolled students, faculty, and other concerned parties. To evaluate the efficiency of communication at Gettysburg College, a quantitative assessment is presented to measure the ease of finding the sustainability webpage, the quality of sustainability-related topics available on the webpage, and quality of webpage design. The webpage is in need of improved text to image ratios, locations of sustainability topics, and data displays. Despite not having a link to the sustainability webpage on the Gettysburg College homepage, sustainability events should be covered and presented on the rotational news feed found on the homepage to maximize outreach to interested parties or simply to add to the definition of Gettysburg College. The fifth priority was integrating sustainability into the Curriculum to build a culture on campus that values academic rigor, supports students as they cultivate intellectual and civic passions, and promotes the development of healthy social relationships and behaviors. The proposed Sustainability Committee on Sustainability in the Curriculum (SCC) will hold sustainability workshops for faculty with the aim to instill sustainability into all academic disciplines, providing all Gettysburg graduates with a means to approach their professional careers in a fashion that is conscious of sustainability. The sixth and last priority was the Sustainability Advisory Committee. Established in 2007, the Sustainability Advisory Committee is currently under review, but it is recommended that the committee restructure itself in accordance with the new Sustainability Committee Bylaws. These bylaws aim to define the purposes, membership, governance, and involvement with the college. With a clearly defined set of goals and methodology, the Sustainability Advisory Committee will be able to improve the solidarity of the sustainability movement on campus as a whole. By following the propositions laid out in the Gettysburg College Sustainability Plan, the student body, faculty, and community alike will become a part of a multi-faceted progression toward a more sustainable future

Determining Best Practices of Peer Mediation Methods in Kalamazoo Public Schools

Determining Best Practices of Peer Mediation methods in Kalamazoo Public Schools Melanie Bourgeau, Dagan Hammar, Neil Hughes, Sarah Kemp, Sydney Spitler, Catherine Kothari BACKGROUND Peer mediation is a method of conflict resolution in which a conflict between two people or groups is guided by a fellow student in order to reach an agreement. Peer mediation has been shown to be an effective tool in helping students resolve conflict and how to respond to future conflicts. This has led to a reduction in school violence and suspensions in schools that have adopted this method. Several methods have been employed in the implementation of peer mediation. However, the two most common methods are the whole school and the cadre approach. The whole school approach requires everyone at the school to be trained, while the cadre approach only requires a few to be trained. PURPOSE The purpose of this study is to explore the various forms of peer mediation and determine best practices for peer mediation in Kalamazoo Public Schools. MATERIALS AND METHODS An online survey was distributed to eligible educators and administrators throughout the Kalamazoo public elementary schools that currently have a peer mediation program. Survey included questions ontheir opinion regarding the effectiveness of peer mediation program currently in place and if there were any barriers to successfully implementing the program. RESULTS 16 Surveys were completed by the study participants at multiple schools in the Kalamazoo area. Overall, the survey respondents found the peer mediation program to be somewhat beneficial to the students (3.69/5; 5 being most beneficial). The results show that the greatest barriers to using the peer mediation program are student willingness (50%) and time (38%). Respondents also feel there is not enough school-wide support for the program (2.94/5) CONCLUSION One of the main barriers to the peer mediation program is having school-wide engagement in the program., Evidence from literature show that the most effective way to implement peer-mediation is through the school-wide approach. Findings from our study show that peer mediation program could be a effective intervention for conflict resolution, however, this is not currently functioning at its full potential. The best way to improve the program, without going to the full school approach, would be to increase awareness and participation at all levels

Using the Consolidated Framework for Implementation Research to Evaluate Clinical Trials: An Example from Multisite Nursing Research

Background The Consolidated Framework for Implementation Research (CFIR) is a comprehensive guide for determining the factors that affect successful implementation of complex interventions embedded in real-time clinical practice. Purpose The study aim was to understand implementation constructs in a multi-site translational research study on readiness for hospital discharge that distinguished study sites with low versus high implementation fidelity. Methods In this descriptive study, site Principal Investigator interviews (from 8 highest and 8 lowest fidelity sites) were framed with questions from 20 relevant CFIR constructs. Analysis used CFIR rules and rating scale (+2 to −2 per site) and memos created in NVivo 11. Findings From a bimodal distribution of differences (1.5 and 5), 7 constructs distinguished high and low fidelity sites with ≥5-point difference. Discussion CFIR provided a determinant framework for identifying elements of a study site\u27s context that impact implementation fidelity and clinical research outcomes

ALMA 1.3 Millimeter Map of the HD 95086 System

Planets and minor bodies such as asteroids, Kuiper-belt objects and comets are integral components of a planetary system. Interactions among them leave clues about the formation process of a planetary system. The signature of such interactions is most prominent through observations of its debris disk at millimeter wavelengths where emission is dominated by the population of large grains that stay close to their parent bodies. Here we present ALMA 1.3 mm observations of HD 95086, a young early-type star that hosts a directly imaged giant planet b and a massive debris disk with both asteroid- and Kuiper-belt analogs. The location of the Kuiper-belt analog is resolved for the first time. The system can be depicted as a broad ($\Delta R/R \sim$0.84), inclined (30\arcdeg$\pm$3\arcdeg) ring with millimeter emission peaked at 200$\pm$6 au from the star. The 1.3 mm disk emission is consistent with a broad disk with sharp boundaries from 106$\pm$6 to 320$\pm$20 au with a surface density distribution described by a power law with an index of --0.5$\pm$0.2. Our deep ALMA map also reveals a bright source located near the edge of the ring, whose brightness at 1.3 mm and potential spectral energy distribution are consistent with it being a luminous star-forming galaxy at high redshift. We set constraints on the orbital properties of planet b assuming co-planarity with the observed disk.Comment: accepted for publication in A
