Putting It All Together: Guiding Principles for Quality After-School Programs Serving Preteens

Successfully navigating early adolescence depends, in large part, on the availability of safe and engaging activities and supportive relationships with adults, yet many preteens have limited access to positive supports and opportunities -- such as high-quality after-school programs -- that could put them on a path to success. Funders, policymakers and practitioners share the common goal of supporting strategies that will have the most long-lasting positive effects on young people.Recognizing this, the Lucile Packard Foundation for Children's Health commissioned P/PV to identify the characteristics of quality after-school programs that are linked to positive outcomes for preteens. Based on the latest research and experience in the field, P/PV developed the publication, Putting It All Together: Guiding Principles for Quality After-School Programs Serving Preteens, along with a companion Resource Guide (http://www.lpfch.org/afterschool/resourceguide.html) that includes links to research and tools to strengthen programs.Putting It All Together focuses on six after-school program components associated with positive outcomes for preteens:Focused and Intentional Strategy: Programs have a clear set of goals, target specific skills, and deliberately plan all aspects of the program with a youth development framework in mind.Exposure: Programs are designed to: a) provide preteens with a sufficient number of hours per week over an extended period of time, that matches program outcome goals; and b) allow preteens to attend a variety of activities.Supportive Relationships: Programs emphasize positive adult-youth relationships regardless of the curriculum.Family Engagement: Programs strive to include families through various strategies, such as clear communication and a welcoming environment.Cultural Competence: Programs have diverse staff whose backgrounds are reflective of participants and who create practices and policies that: a) make services available to and inclusive of a variety of populations; and b) help participants understand and value a broad range of cultures.Continuous Program Improvement: Programs strengthen quality through an ongoing and integrated process of targeted staff training, coaching and monitoring, and data collection and analysis.While a host of factors, including organizational capacity, the needs of the youth served and the resources available, all play a role in determining a program's ability to achieve its goals, research suggests that these guiding principles are essential for program quality. That quality, in turn, is the foundation for positive results for youth.NOTE: This version of Putting It All Together contains a full list of endnotes and references, which we chose to omit from hard copies of the report, in the interest of brevity

More Time For Teens: Understanding Teen Participation -- Frequency, Intensity and Duration -- In Boys & Girls Clubs

Written midway through a three-year longitudinal evaluation of the role Boys & Girls Clubs play in the lives of the youth they serve, this report explores a topic of continuing interest to program operators and funders: What does it take to involve teens in positive out-of-school-time activities? Drawing on survey data from a low-income, ethnically diverse sample of approximately 400 seventh and eighth graders, Clubs attendance data tracked over a period of 17 months, and in-depth interviews with a sample of ninth graders, More Time for Teens identifies a set of factors that appear to contribute to three specific aspects of Club participation: frequency, duration and retention. The report highlights links found between accessible, safe places that provide a variety of informal and formal activities of interest to teens and higher levels of participation. It also distills lessons for programs interested in boosting teen participation. These include establishing relationships when children are younger (these relationships often endure through the teen years), taking into account the importance teens place on friendships and working with teens to establish flexibility in attendance policies as they enter their high school years

Apparatus and method for centrifugation and robotic manipulation of samples

A device for centrifugation and robotic manipulation of specimen samples, including incubating eggs, and uses thereof are provided. The device may advantageously be used for the incubation of avian, reptilian or any type of vertebrate eggs. The apparatus comprises a mechanism for holding samples individually, rotating them individually, rotating them on a centrifuge collectively, injecting them individually with a fixative or other chemical reagent, and maintaining them at controlled temperature, relative humidity and atmospheric composition. The device is applicable to experiments involving entities other than eggs, such as invertebrate specimens, plants, microorganisms and molecular systems

A global experiment on motivating social distancing during the COVID-19 pandemic

Finding communication strategies that effectively motivate social distancing continues to be a global public health priority during the COVID-19 pandemic. This cross-country, preregistered experiment (n = 25,718 from 89 countries) tested hypotheses concerning generalizable positive and negative outcomes of social distancing messages that promoted personal agency and reflective choices (i.e., an autonomy-supportive message) or were restrictive and shaming (i.e., a controlling message) compared with no message at all. Results partially supported experimental hypotheses in that the controlling message increased controlled motivation (a poorly internalized form of motivation relying on shame, guilt, and fear of social consequences) relative to no message. On the other hand, the autonomy-supportive message lowered feelings of defiance compared with the controlling message, but the controlling message did not differ from receiving no message at all. Unexpectedly, messages did not influence autonomous motivation (a highly internalized form of motivation relying on one’s core values) or behavioral intentions. Results supported hypothesized associations between people’s existing autonomous and controlled motivations and self-reported behavioral intentions to engage in social distancing. Controlled motivation was associated with more defiance and less long-term behavioral intention to engage in social distancing, whereas autonomous motivation was associated with less defiance and more short- and long-term intentions to social distance. Overall, this work highlights the potential harm of using shaming and pressuring language in public health communication, with implications for the current and future global health challenges

Sharing and community curation of mass spectrometry data with Global Natural Products Social Molecular Networking

The potential of the diverse chemistries present in natural products (NP) for biotechnology and medicine remains untapped because NP databases are not searchable with raw data and the NP community has no way to share data other than in published papers. Although mass spectrometry techniques are well-suited to high-throughput characterization of natural products, there is a pressing need for an infrastructure to enable sharing and curation of data. We present Global Natural Products Social molecular networking (GNPS, http://gnps.ucsd.edu), an open-access knowledge base for community wide organization and sharing of raw, processed or identified tandem mass (MS/MS) spectrometry data. In GNPS crowdsourced curation of freely available community-wide reference MS libraries will underpin improved annotations. Data-driven social-networking should facilitate identification of spectra and foster collaborations. We also introduce the concept of ‘living data’ through continuous reanalysis of deposited data

Hydrothermal sediments record changes in deep water oxygen content in the SE Pacific

The distribution of redox?sensitive metals in sediments is potentially a proxy for past ocean ventilation and productivity, but deconvolving these two major controls has proved difficult to date. Here we present a 740 kyr long record of trace element concentrations from an archived sediment core collected at ?15°S on the western flank of the East Pacific Rise (EPR) on 1.1 Myr old crust and underlying the largest known hydrothermal plume in the world ocean. The downcore trace element distribution is controlled by a variable diagenetic overprint of the inferred primary hydrothermal plume input. Two main diagenetic processes are operating at this site: redox cycling of transition metals and ferrihydrite to goethite transition during aging. The depth of oxidation in these sediments is controlled by fluctuations in the relative balance of bottom water oxygen and electron donor input (organic matter and hydrothermal sulfides). These fluctuations induce apparent variations in the accumulation of redox?sensitive species with time. Subsurface U and P peaks in glacial age sediments, in this and other published data sets along the southern EPR, indicate that basin?wide changes in deep ocean ventilation, in particular at glacial?interglacial terminations II, III, IV, and V, alter the depth of the oxidation front in the sediments. These basin?wide changes in the deep Pacific have significant implications for carbon partitioning in the ocean?atmosphere system, and the distribution of redox?sensitive metals in ridge crest sediment can be used to reconstruct past ocean conditions at abyssal depths in the absence of alternative proxy records
