The Plain Talk Implementation Guide

Public/Private Ventures' cross-site evaluation determined that the Plain Talk framework enabled communities to change the ways adults communicated with teens. It also showed that youth in Plain Talk communities who talked to adults were less likely to have an STD or a pregnancy. These results confirmed the validity of three basic Plain Talk components: Community Mapping, Walkers and Talkers, and Home Health Parties

Copy That: Guidelines for Replicating Programs to Prevent Teen Pregnancy

Published jointly with The National Campaign to Prevent Teen Pregnancy, this report provides guidance about the replication of effective pregnancy prevention programs. It urges stakeholders to ask a variety of key questions when considering replication: Is the program effective? (What kind of evaluation has been done and what did it show?) What are the essential elements that make the program effective? Is the program ready to be replicated (with clear documentation)? And what is the replication plan? The report gleans lessons from the replication experiences of three programs: The Teen Outreach Program, The CAS-Carrera Program, and Plain Talk, whose national replication is being managed by P/PV

Discovery of Two Moth Species New to Michigan (Lepidoptera: Noctuidae, Tortricidae)

Rhizedra lutosa (Noctuidae) and Argyrotaenia cockerellana (Tortricidae), are reported from Michigan for the first time, from remnant patches of mesic lakeplain prairie in Sumpter Township, Wayne Co. Rhizedra lutosa is a Eurasian species that is rapidly establishing populations across the United States. Argyrotaenia cockerellana is primarily known from the western United States, with eastern records from Nebraska and Ontario, Canada

Ecological Traits Fail to Consistently Predict Moth Species Persistance in Managed Forest Stands

Species traits have been used as predictors of species extinction and colonization probabilities in fragmented landscapes. Thus far, trait-based analytical frameworks have been less commonly employed as predictive tools for species persistence following a disturbance. I tested whether life history traits, dietary traits, and functional traits were correlated with moth species persistence probabilities in forest stands subjected to varying levels of timber harvest. Three harvest treatments were used: control stands (unharvested since 1960), shelterwood cut stands (15% canopy removed), and patch cut stands (80% standing bole removed). Logistic regression models were built to assess whether species persistence probabilities were a function of species traits; separate models were constructed for each level of timber harvest treatment. Species persistence probabilities were mainly a function of pre-harvest abundances. Species traits had idiosyncratic effects on species persistence depending on the level of timber harvest employed. These results suggest that species traits may indirectly influence how moth species assemblages change as a result of forest management by determining pre-harvest abundance rather than persistence per se. The absence of significant trait effects on persistence probabilities may also reflect prior reduction in species trait space. That is, the range of species trait combinations sampled in this study was much lower than observed in historically unlogged eastern deciduous forest systems. Thus, the lack of significant trait-persistence correlations observed here might indicate historic extinctions of species from prior logging events that have not been offset by post-harvest recovery of original species assemblages

The Power of Plain Talk: Exploring One Program's Influence on the Adolescent Reproductive Health Field

Launched by the Annie E. Casey Foundation in the early 1990s, Plain Talk is a community-based initiative that seeks to reduce the incidence of teen pregnancy and STDs by improving adult/teen communication about sex. A key component of the program is parental involvementwhich was once seen by many in the adolescent reproductive health (ARH) field as a necessary evil rather than important partnership. To determine if Plain Talk had a positive influence on the field's view of parental involvement, and on a number of other related issues, P/PV conducted interviews with 15 leaders from prominent ARH organizations, first in 2003 and again in 2005. This report compiles the results

Laying a Solid Foundation: Strategies for Effective Program Replication

With limited funds available for social investment, policymakers and philanthropists are naturally interested in supporting programs with the greatest chance of effectiveness and the ability to benefit the largest number of people. When a program rises to the fore with strong, proven results, it makes sense to ask whether that success can be reproduced in new settings.Program replication is premised on the understanding that many social problems are common across diverse communities -- and that it is far more cost-effective to systematically replicate an effective solution to these problems than to continually reinvent the wheel. When done well, replication of strong social programs has the potential to make a positive difference not just for individual participants, but indeed for entire communities, cities and the nation as a whole.Yet despite general agreement among policymakers and philanthropists about the value of replication, successful efforts to bring social programs to scale have been limited, and rarely is replication advanced through systematic public policy initiatives. More often, replication is the result of a particular social entrepreneur's tireless ambition, ability to raise funds and marketing savvy. The failure to spread social program successes more widely and methodically results from a lack of knowledge about the science and practice of replication and from the limited development of systems -- at local, state or federal levels -- to support replication.Fortunately, there seems to be growing awareness of the need to invest in such systems. For example, the 2009 Serve America Act included authorization for a new Social Innovation Fund that would "strengthen the infrastructure to identify, invest in, replicate and expand" proven initiatives. The Obama administration recently requested that Congress appropriate $50 million to this fund, with a focus on "find(ing) the most effective programs out there and then provid(ing) the capital needed to replicate their success in communities around the country."But more than financial capital is required to ensure that when a program is replicated, it will continue to achieve strong results. Over the past 15 years, Public/ Private Ventures (P/PV) has taken a deliberate approach to advancing the science and practice of program replication. Through our work with a wide range of funders and initiatives, including the well-regarded Nurse-Family Partnership, which has now spread to more than 350 communities nationwide, we have accumulated compelling evidence about specific strategies that can help ensure a successful replication. We have come to understand that programs approach replication at different stages in their development -- from fledgling individual efforts that have quickly blossomed and attracted a good deal of interest and support to more mature programs that have slowly expanded their reach and refined their approach over many years. There are rarer cases in which programs have rigorous research in hand proving their effectiveness, multiple sites in successful operation and willing funders prepared to support large-scale replication.Regardless of where a promising program may be in its development, our experience points to a number of important lessons and insights about the replication process, which can inform hard decisions about whether, when and how to expand a program's reach and total impact. In the interest of expanding programs that work, funders sometimes neglect the structures and processes that must be in place to support successful replication. These structures should be seen as the "connective tissue" between a program that seeks to expand and the provision of funding for that program's broad replication.This report represents a synthesis of P/PV's 30 years of designing, testing and replicating a variety of social programs and explains the key structures that should be in place before wide-scale replication is considered. It is designed to serve as a guide for policymakers, practitioners and philanthropists interested in a systematic approach to successful replication

Habitat Characterization of Five Rare Insects in Michigan (Lepidoptera: Hesperiidae, Riodinidae, Satyridae; Homoptera: Cercopidae)

Over 80 species of insects are listed as endangered, threatened, or special concern under Michigan\u27s endangered species act. For the majority of these species, detailed habitat information is scant or difficult to interpret. We describe the habitat of five insect species that are considered rare in Michigan: Lepyronia angulifera (Cercopidae), Prosapia ignipectus (Cercopidae), Oarisma poweshiek (Hesperiidae), Calephelis mutica (Riodinidae), and Neonympha mitchellii mitchellii (Satyridae). Populations of each species were only found within a fraction of the plant communities deemed suitable based upon previous literature. Furthermore, individuals of each species were observed to be closely affiliated with just a few vegetation associations within larger plant communities. Restriction of these species to particular microhabitats was determined to be, in part, due to ecological or behavioral specialization of each insect species. We believe that the most holistic man­agement and conservation practices for these rare insects in Michigan should focus on protecting the integrity of both the plant community and the micro- habitat upon which these species depend

CHARDA: Causal Hybrid Automata Recovery via Dynamic Analysis

We propose and evaluate a new technique for learning hybrid automata automatically by observing the runtime behavior of a dynamical system. Working from a sequence of continuous state values and predicates about the environment, CHARDA recovers the distinct dynamic modes, learns a model for each mode from a given set of templates, and postulates causal guard conditions which trigger transitions between modes. Our main contribution is the use of information-theoretic measures (1)~as a cost function for data segmentation and model selection to penalize over-fitting and (2)~to determine the likely causes of each transition. CHARDA is easily extended with different classes of model templates, fitting methods, or predicates. In our experiments on a complex videogame character, CHARDA successfully discovers a reasonable over-approximation of the character's true behaviors. Our results also compare favorably against recent work in automatically learning probabilistic timed automata in an aircraft domain: CHARDA exactly learns the modes of these simpler automata.Comment: 7 pages, 2 figures.

Great Diversity of Insect Floral Associates May Partially Explain Ecological Success of Poison Ivy (\u3ci\u3eToxicodendron Radicans\u3c/i\u3e Subsp. \u3ci\u3eNegundo\u3c/i\u3e [Greene] Gillis, Anacardiaceae)

Little is known about insect floral associates of poison ivy (Toxicodendron radicans, Anacardiaceae), despite the species’ ubiquity and importance in nature and society. Poison ivy’s pollination syndrome and results from prior studies suggest that the plant is not specialized for any particular pollinator type; however, a systematic survey exploring this hypothesis has been lacking. For this study, insect floral associates of Toxicodendron radicans subsp. negundo from a central Iowa site were observed during the flowering season of 2005. Thirty- seven distinct insect floral associates were observed: 8 coleopterans (beetles), 7 dipterans (flies), 2 hemipterans (true bugs), 19 hymenopterans (ants, bees, wasps), and 1 lepidopteran (butterfly). Hymenopterans appeared to be the most important contributors to poison ivy pollination on a per species basis; however, coleopterans and dipterans were also frequent associates. Poison ivy’s ability to utilize a diverse assemblage of insect pollinators may partially explain its ecological success in varied habitats
