Historical framework to explain long-term coupled human and natural system feedbacks: application to a multiple-ownership forest landscape in the northern Great Lakes region, USA
Current and future human and forest landscape conditions are influenced by the cumulative, unfolding history of social-ecological interactions. Examining past system responses, especially unintended consequences, can reveal valuable insights that promote learning and adaptation in forest policy and management. Temporal couplings are complex, however; they can be difficult to trace, characterize, and explain. We develop a framework that integrates environmental history into analysis of coupled human and natural systems (CHANS). Our study demonstrates how historical data and methods can help to explain temporal complexity of long-term CHANS feedbacks. We focus on two sources of temporal complexity: legacy effects and lagged interactions. We apply our framework to a multiple-ownership forest landscape comprising tribal and nonindustrial private forest ownerships in Wisconsin. Our framework features four elements that help investigators better understand complex systems through time: (1) a temporal axis parsed into historical periods (periodization), (2) representation of links between historical periods and system feedbacks, (3) representation of land ownership history, and (4) nested geographical scales of historical analysis. The framework can help to reveal legacy effects and lagged interactions, illuminate turning points and periods in system dynamics, and distil insights from unintended consequences that inform institutional and policy adaptation. We also assess the validity of using land ownership to represent the social component of CHANS models. When treated as a categorical variable and interpreted in historical context, land ownership can validly represent decision-making structure, culture, and knowledge system in spatially explicit social-ecological models
Queerness and Dating Violence Among Adolescent Mothers in Foster Care
Adolescent mothers, queer, and foster youth are all groups at heightened vulnerability for teen dating violence victimization. It is unknown how mothers in residential foster care perceive and experience violence within same-sex relationships. Literature suggests, however, that violence within these contexts may be met by minimization and even denial on behalf of practitioners (e.g., social workers) who may not have a comprehensive understanding of how to best serve queer clients, especially clients who may not be automatically perceived as queer (e.g., adolescent mothers). The present study utilized a mixed qualitative methodological approach to triangulate the perspectives of program staff (n = 12) who worked at a residential foster care facility through individual interviews with the views and experiences of adolescent mother residents (n = 13) through two focus groups. By taking a queer theoretical perspective, this study interpreted the fluid sexual performativity and viewpoints concerning violence victimization among foster care mothers within the context of a heteronormative service provision model. Specifically, we found that the meaning of relationships between mothers was minimized and violence between same-sex dating partners was interpreted as normative peer conflict. Such findings run contrary to youths’ experiences and perspectives, which holds important ramifications for practitioner–client interaction and service delivery
Preservice Educators\u27 Perceptions About Two Types of Vocabulary Progress Monitoring Measures
The purpose of this study was to contrast the use of two types of progress monitoring measures in a university introductory course about special education taught face to face across 15 weeks. Researchers used curriculum-based measurement (CBM; Deno, 1985) methodology to develop vocabulary-matching (see Espin, Busch, Lembke, Hampton, Seo, & Zukowski, 2013) and vocabulary-selection probes. Each alternate form sampled words from the larger pool of 150 special education-related terms from the textbook glossary (Hallahan, Kauffman, & Pullen, 2015). Research questions focused on the examination of participant feedback about the two probe types used during vocabulary assessment activities in the course and participant growth in vocabulary knowledge as well as their knowledge of progress monitoring practices. Survey results indicated that participants preferred (75%) the matching probes to the selection probes (25%) and specified that the matching probes (93%) were good indicators of their knowledge in the course compared to the selection probes (54%). Participants reported that participating in the vocabulary assessment activities helped them understand how progress monitoring tools can be used to assess content area knowledge and thought it would be feasible and beneficial for them to use with their future students. Although more than three-quarters of participants felt the graphs for both types of measures were useful for seeing their progress in course vocabulary knowledge, interestingly, less than a quarter of participants reported that taking the probes and seeing their progress caused them to alter their study habits for the course. General and special education preservice teachers (n = 29) demonstrated improvement in vocabulary-matching and vocabulary-selection measures from beginning probes to last probes. Significant growth was detected on the vocabulary pre-/posttest measure and the CBM knowledge pre-/posttest measure, indicating that students grew in their course-related vocabulary knowledge and their knowledge of CBM across the semester. Additionally, in an extension of this study, a subset of vocabulary matching and vocabulary selection probes were administered to preservice educators during a subsequent section of the same course offered online during a shortened summer term. Participants (n = 11) took vocabulary pre/posttests online as well as four alternate forms of each probe type across the 5-week course. Then, they rated their preferences regarding the probe types. Interestingly, this group preferred the selection probes (100%) to the matching probes, primarily due to its ease in completing the measure online. They also indicated that the selection probes were good indicators of their knowledge in the course compared to the matching probes. Implications for using CBM vocabulary measures in face-to-face and online university coursework are addressed
Economic Stress Among Low Income Latino Adolescent Fathers: An Application of the Vulnerability-Stress-Adaptation Model
Latino youth are more likely to live under the poverty line and to become adolescent parents. Although research exists examining adolescent mothers, less is known about adolescent fathers, particularly Latino adolescent fathers. Much of what does exist uses a deficit lens, as opposed to one of strength and resilience. Although adolescent fathers sometimes do struggle in their transition to fatherhood, it is critical to understand the positive ways in which they adapt. The present study uses in-depth interviews and applies the vulnerability-stress-adaptation (VSA) model to understand parental adaptation processes among a sample of low-income Latino adolescent fathers (N = 11). Despite economic vulnerability, including low income and limited resources, fathers’ aspirations to provide for their children served as an adaptive mechanism. These aspirations were influenced by the quality of their relationship with the mother of their children as well as by cultural influences from their families-of-origin. Findings indicated the importance of a positive, holistic family experience that includes cultural notions of familism. By identifying the processes by which adolescent fathers experience vulnerabilities, stress, and adaptation to those stressors, it is possible to develop and implement culturally responsive and strengths-based services and policies to better support their transition, including those related to job readiness, relationship education, and family involvement

Why are you here again? Concordance between consumers and providers about the primary concern in recurring psychiatric visits
Patient-centered care has become increasingly important over the last decade, both in physical and mental health care. In support of patient-centered care, providers need to understand consumers׳ primary concerns during treatment visits. The current study explored what primary concerns were brought to recurring psychiatric visits for a sample of adults with severe mental illness (N=164), whether these concerns were concordant with those recognized by providers, and which factors predicted concordance. We identified 17 types of primary concerns, most commonly medications and symptoms, with only 50% of visits showing evidence of at least partial agreement between consumers and providers. Contrary to expectations, consumer demographics, activation, trust, and perceptions of patient-centeredness were not predictive, while greater preferences for autonomy predicted poorer agreement. Our findings highlight the need for interventions to promote a shared understanding of primary concerns in recurring psychiatric visits. Further attention is needed to ensure the provision of patient-centered care such that consumer concerns are acknowledged and addressed within recurring psychiatric visits
Protein Delivery of an Artificial Transcription Factor Restores Widespread Ube3a Expression in an Angelman Syndrome Mouse Brain.
Angelman syndrome (AS) is a neurological genetic disorder caused by loss of expression of the maternal copy of UBE3A in the brain. Due to brain-specific genetic imprinting at this locus, the paternal UBE3A is silenced by a long antisense transcript. Inhibition of the antisense transcript could lead to unsilencing of paternal UBE3A, thus providing a therapeutic approach for AS. However, widespread delivery of gene regulators to the brain remains challenging. Here, we report an engineered zinc finger-based artificial transcription factor (ATF) that, when injected i.p. or s.c., crossed the blood-brain barrier and increased Ube3a expression in the brain of an adult mouse model of AS. The factor displayed widespread distribution throughout the brain. Immunohistochemistry of both the hippocampus and cerebellum revealed an increase in Ube3a upon treatment. An ATF containing an alternative DNA-binding domain did not activate Ube3a. We believe this to be the first report of an injectable engineered zinc finger protein that can cause widespread activation of an endogenous gene in the brain. These observations have important implications for the study and treatment of AS and other neurological disorders
Job-Related Burnout among Juvenile Probation Officers: Implications for Mental Health Stigma and Competency
The high demands and responsibilities of probation work, particularly with juvenile clients, may lead to burnout, which can negatively impact how probation officers work with clients, particularly individuals with behavioral health concerns. Yet, research examining burnout and related outcomes among juvenile probation officers (JPOs) is limited. We surveyed 246 JPOs in a Midwestern state to identify the prevalence, predictors, and potential outcomes of burnout. JPOs reported moderate levels of burnout; about 30% of the sample scored in the high range for emotional exhaustion and cynicism. Contrary to study hypotheses, there were no group-level differences in burnout scores across gender, race/ethnicity, age, or education. In regression models, burnout was predicted by being White (vs. minority), serving in an urban (vs. rural) county, dissatisfaction with department guidelines, job dissatisfaction, viewing job role as more treatment-oriented along the enforcement−treatment continuum, and turnover intention. JPOs with burnout were more likely to endorse mental health stigma and lack of mental health competency to address juvenile clients with behavioral health concerns. Findings suggest burnout prevention and intervention programs should be considered for JPOs to increase job satisfaction, limit job turnover, reduce burnout, and possibly increase effective practices for managing juvenile clients with behavioral health needs
