RESUMO

PURPOSE: This study marks the 50th anniversary of NAPCRG (formerly the North American Primary Care Research Group) by examining social connections among members. METHODS: This descriptive social network analysis was conducted via the Program to Analyze, Record, and Track Networks to Enhance Relationships (PARTNER) survey tool. RESULTS: Responses from 906 participants resulted in 1,721 individuals with 5,196 partner relationships. Most relationships (60%) were characterized as having an integrated level of collaboration. Many relationships led to a research paper (58%) or a grant (34%). CONCLUSIONS: This social network analysis of NAPCRG members' relationships described over 5,000 relationships, many producing publications, grants, and perceived advancements in primary care.

RESUMO

With our field's strong focus on context for understanding and acting on social problems, community psychologists have frequently elevated the importance of employing systems thinking and methods that help us to understand systems more effectively. As a result, community psychologists have adopted some methods from the interdisciplinary field of systems science. In this virtual special issue, we will compare how several of these approaches have been used in publications in the AJCP in the last 50 years. We identify differences in their popularity, implementation with communities, and how they create generative discussion in the field. We conclude by looking to the future to explore ways community psychology can deepen engagement with methods from systems science.

RESUMO

This study draws on two communities theory to address two major research questions related conceptions of research in educational practice and policy. First, how do educators conceptualize research? Second, to what extent do educators' conceptions of research align with recent U.S. federal educational policies? We conducted 90 semi-structured interviews with educators in the United States, asking them what comes to mind when they think of research. We used open, axial, and selective coding to characterize educators' conceptions of research. We also compared educators' conceptions of research to two U.S. federal educational policies that define scientifically based research and evidence-based interventions. Findings indicate that educators and policies defined research in similar ways, but each included some unique characteristics. Implications from the study include the need for increased communication between federal policy-makers and educators and improved reporting by researchers to better attend to the needs of educators and policymakers.

RESUMO

Quantification of tumour-specific molecular markers at the RNA and DNA level for treatment response monitoring is crucial for risk-adapted stratification and guidance of individualized therapy in leukaemia and other malignancies. Most pediatric leukaemias and solid tumours of mesenchymal origin are characterized by a relatively low mutation burden at the single nucleotide level and the presence of recurrent chromosomal translocations. The genomic fusion sites resulting from translocations are stable molecular tumour markers; however, repeat-rich DNA sequences flanking intronic breakpoints limit the design of high sensitivity PCR assays for minimal residual disease (MRD) monitoring. Here, we quantitatively evaluated the impact of repeat elements on assay selection and the feasibility of using extended amplicons (≤1330 bp) amplified by droplet digital PCR to monitor pediatric chronic myeloid leukaemia (CML). Molecular characterization of 178 genomic BCR-ABL1 fusion sites showed that 64% were located within sequence repeat elements, impeding optimal primer/probe design. Comparative quantification of DNA and RNA BCR-ABL1 copy numbers in 687 specimens from 55 pediatric patients revealed that their levels were highly correlated. The combination of droplet digital PCR, double quenched probes and extended amplicons represents a valuable tool for sensitive MRD assessment in CML and may be adapted to other translocation-positive tumours.

RESUMO

The presence of a research-practice gap is recognized across multiple fields including education, psychology, and public health. In this paper, we examine which of five structural types of brokerage are most and least effective in bridging this research-practice gap in the context of education. Using a small world survey design, we tracked how a statewide random sample of 247 K-12 principals and superintendents in Michigan seek information about social skills programs from brokering individuals and organizations. We find that some triadic brokerage structures are more effective than others in closing the communication gap between practitioners and researchers. Specifically, educators relying on itinerant brokerage, which circulates information between members of the same community, were five times less likely to obtain information from a researcher. In contrast, educators relying on representative or liaison brokerage, which facilitate information transfer between members of different communities, were more than twice as likely to obtain information from a researcher. We conclude by discussing implications for the development of interventions designed to facilitate information sharing between practitioners and researchers.

RESUMO

Despite growing interest in data visualization and graphically aided reporting, the evaluation literature could benefit from additional guidance on systematically integrating visual communication design and marketing into comprehensive communication strategies to improve data dissemination. This article describes the role of targeted communication strategies-based on visual communications, design, and marketing theory-in producing more effective reports. In evaluation practice, well-synthesized and translated reports often require the integration of data from multiple sources, methods, and/or time points to communicate complex findings in ways that elicit productive responses. Visual communication strategies, such as project branding or designing actionable tools with marketing principles in mind, can be applied to optimize effective reporting of complex evaluation findings. This article references a longitudinal, mixed-method evaluation of public school administrators in Michigan to illustrate the application of a systematic communication design framework to produce several graphically aided project materials and subsequent findings reports.

RESUMO

PURPOSE: We apply diffusion of innovations theory to examine two key research questions designed to inform efforts to improve the research-practice gap in education: (1) Are there distinct types of educators that differ in their prioritization of the compatibility, observability, complexity, relative advantage, and trialability of research? and (2) Are educators' roles or context associated with their categorization in this typology? RESEARCH METHODS: Using semi-structured interview data in two Michigan counties from intermediate school district staff (N=24), district central office staff (N=18), principals (N=22), and school building staff (N=23), we first used directed content analysis to code for mentions of compatibility, observability, complexity, relative advantage, and trialability. Next, using the coded data, we conducted a hierarchical agglomerative cluster analysis and follow-up cross-tabulations to assess whether cluster memberships were associated with educators' roles or county context. FINDINGS: Educators in our sample could be categorized in one of five clusters distinguished primarily by different patterns of prioritization of the compatibility, observability, and complexity of research. Membership in these clusters did not vary by role but did vary by county, suggesting the importance of context for educators' perceptions of research. IMPLICATIONS FOR RESEARCH AND PRACTICE: These findings suggest that narrowing the research-practice gap in education will require attending to multiple audiences of educators with distinct priorities that guide their perceptions and use of educational research and evidence-based practices.

RESUMO

Measuring the use of research evidence (URE) by schools has become a central of education researchers. However, it has proven challenging due to low response rates, social desirability bias, and costly or time consuming data collection methods. To overcome these challenges and meet the needs of research focused on URE, this paper introduces a non-reactive archival measure: Archival Search of Use of Research Evidence (ASURE). ASURE counts references to research or evidence on a school's or school district's website to capture the extent of its rhetorical use of research evidence. After illustrating the collection of ASURE in all public school districts in Michigan (N = 595), we use data on these districts to show that ASURE is reliable and valid, and thus offers a promising new strategy for measuring URE in schools. We conclude by considering future steps for exploring ASURE not simply as a measure of URE in schools, but instead as a measurement strategy for assessing URE in a broad range of organizational contexts.

RESUMO

In this study, we explored the extent to which educators discuss and prioritize Rogers' (Diffusion of innovations, The Free Press: New York, 1995) five attributes of innovations-relative advantage, compatibility, complexity, observability, and trialability-in the context of research use. Using a directed content analysis of 54 semi-structured interviews and exemplar quotes, we describe how educators mentioned compatibility most frequently, but also commonly invoked observability and complexity in their discussions of research use. Our results also revealed key differences between educators in executive and non-executive roles. We discuss the implications of our findings for closing the research-practice gap in school-based mental health services and psychosocial interventions.

RESUMO

We propose transaction cost economics theory as a tool for exploring when school administrators rely on information from two types of sources: internal sources like their own colleagues, and external sources like researchers and government agencies. The theory's application is illustrated in a comparative case study of two public school districts in Michigan. Consistent with the theory's predictions, the smaller, homogeneous, high-performing district used more external sources of information, while the larger, diverse, low-performing district used internal sources of information. We conclude by identifying some strengths and limitations of the theory, which can serve as starting points for debate.

RESUMO

Background Malignant melanoma (MM) is a common malignancy in adults while it is rare in children. Thus, information on clinical behavior of pediatric MM is incomplete. Patients The German Pediatric Rare Tumor Registry (STEP) presents a prospective analysis of 60 childhood MM cases diagnosed between June 2006 and December 2014. Method Patients' ages ranged between 0 and 17 years at initial diagnosis (median age 9.6 years). Information on patient's and tumor characteristics was obtained by standardized documentation. Three-year overall survival (OS) and event-free survival (EFS) were estimated by the Kaplan-Meier test. Results Follow-up ranged from 0 to 116 months with a median of 36.5 months, however, univariate analysis was performed for 46 cases with a follow-up > 3 months, only. Cases with spitzoid histotype (40%) did not show a significantly different outcome compared to cases with non-spitzoid MM. Breslow thickness ≤ 2.00 mm was identified in 30% of the cases and 18% were Clark level I to III. Adjuvant therapy was used in 45% of cases. OS at 3 years was 100%, EFS 95.2%. Conclusion We present a series of cases with a high number of spitzoid malignant melanoma and advanced pediatric melanoma, but surprisingly good overall survival rates. Spitzoid and non-spitzoid MM do not differ in clinical behavior and survival.

RESUMO

INTRODUCTION: Colorectal carcinoma (CRC) is the second most common adult cancer in Germany, however, it is extremely rare in children and adolescents. In these patients, previous literature describes aggressive behavior and diagnosis at advanced stage. METHOD: Thirty-one patients with CRC age ≤ 18 years and treated between 1990 and 2012 have been identified through the structures and registries of the German Society for Pediatric Oncology and Hematology. RESULTS: The age range was 9-18 years (median 13.5 years); the median follow-up time was 43.9 months (range 1-124 months). Twenty-six patients (84%) were tested for a genetic tumor syndrome (GTS); of these, 11 patients (35% of all patients) tested positive (eight cases of Lynch syndrome, one patient with familial adenomatous polyposis, two patients with constitutional mismatch repair deficiency). An unfavorable histology was reported in 55% of the records (n = 17), a poor differentiation (grade III) in 68% of carcinoma (n = 21). Overall survival (OS) and event-free survival at 5 years was 52.0% and 65.6%, respectively. Five-year survival according to stage was 100% in stage II (n = 2), 100% in stage III (n = 13), and 12.9% in stage IV (n = 15; P < 0.001). Five-year OS in patients with and without a defined GTS was 100% and 36.5% (P = 0.019), respectively. CONCLUSION: Children and adolescents with CRC are frequently diagnosed in advanced stages and have an unfavorable prognosis. In this study, a high percentage of pediatric CRC patients presented with a tumor predisposition syndrome and showed an especially favorable OS.

RESUMO

Many natural sounds have spectrotemporal signatures only on a statistical level, e.g. wind, fire or rain. While their local structure is highly variable, the spectrotemporal statistics of these auditory textures can be used for recognition. This suggests the existence of a neural representation of these statistics. To explore their encoding, we investigated the detectability of changes in the spectral statistics in relation to the properties of the change. To achieve precise parameter control, we designed a minimal sound texture--a modified cloud of tones--which retains the central property of auditory textures: solely statistical predictability. Listeners had to rapidly detect a change in the frequency marginal probability of the tone cloud occurring at a random time.The size of change as well as the time available to sample the original statistics were found to correlate positively with performance and negatively with reaction time, suggesting the accumulation of noisy evidence. In summary we quantified dynamic aspects of change detection in statistically defined contexts, and found evidence of integration of statistical information.

RESUMO

Addressing complex problems in communities has become a key area of focus in recent years (Kania & Kramer, 2013, Stanford Social Innovation Review). Building on existing approaches to understanding and addressing problems, such as action research, several new approaches have emerged that shift the way communities solve problems (e.g., Burns, 2007, Systemic Action Research; Foth, 2006, Action Research, 4, 205; Kania & Kramer, 2011, Stanford Social Innovation Review, 1, 36). Seeking to bring clarity to the emerging literature on community change strategies, this article identifies the common features of the most widespread community change strategies and explores the conditions under which such strategies have the potential to be effective. We identify and describe five common features among the approaches to change. Then, using an agent-based model, we simulate network-building behavior among stakeholders participating in community change efforts using these approaches. We find that the emergent stakeholder networks are efficient when the processes are implemented under ideal conditions.

RESUMO

Despite widespread recognition of a research-practice gap in multiple service sectors, less is known about how pre-existing communication channels facilitate the flow of information between researchers and practitioners. In the current study, we applied an existing typology of brokerage developed by Gould and Fernandez (Sociol Methodol 19:89-126, 1989) to examine what types of brokerage facilitate information spread between researchers and educational practitioners. Specifically, we conducted semi-structured interviews with 19 school administrators and staff in two public school districts regarding their experiences searching for information about instructional, health, and social skills programs. Using deductive content analysis, we found evidence of all five types of brokerage identified by Gould and Fernandez (1989). However, only three types of brokerage-gatekeepers, representatives, and liaisons-were involved in the flow of information between school administrators and researchers. Moreover, information transfer often occurred in longer chains that involved multiple, distinct types of brokerage. We conclude with the broad implications of our findings for narrowing the research-practice gap by improving researchers' dissemination efforts and practitioners' search for information.

RESUMO

INTRODUCTION: The purpose of this study is to assess a cross-sector, interorganizational network addressing adverse childhood experiences (ACEs) in a rural Colorado community. We characterize the organizations in the network, assess their awareness of ACEs, and evaluate how they participate in the network. We also assess the network health. METHOD: Employing a social network analysis approach, we collected survey data from 45 organizations that support young children and their families, including nonprofits, health care clinics, and early childhood education centers, among others. RESULTS: On average, nonprofit organizations had relationships with a greater percentage of network members than other types of organizations. Network members engaged in relationships focused on a wide range of activities (e.g., client assessments, sharing information, providing services), with some organizational types leading the network in certain activities. Scores across all dimensions of trust and value were above 3 (range: 2.1-3.8), which is advantageous for a network and network relationships existed across a range of relational intensities (from awareness to organizational integration). DISCUSSION: Nonprofit organizations that reported high levels of connectedness in the network were able to effectively mobilize the ACEs network. Health clinics participated in a greater share of relationships involving assessment, service provision, and tool sharing than other types of organizations. As such, health care clinics may serve as leaders in directly serving children and families experiencing ACEs in rural communities. The rural context may also explain high levels of trust and value, which can serve as assets for future network development and mobilization.

RESUMO

Everyday life's perceptual decision-making is informed by experience. In particular, temporal expectation can ease the detection of relevant events in noisy sensory streams. Here, we investigated if humans can extract hidden temporal cues from the occurrences of probabilistic targets and utilize them to inform target detection in a complex acoustic stream. To understand what neural mechanisms implement temporal expectation influence on decision-making, we used pupillometry as a proxy for underlying neuromodulatory activity. We found that participants' detection strategy was influenced by the hidden temporal context and correlated with sound-evoked pupil dilation. A model of urgency fitted on false alarms predicted detection reaction time. Altogether, these findings suggest that temporal expectation informs decision-making and could be implemented through neuromodulatory-mediated urgency signals.

RESUMO

Cholinergic basal forebrain (CBF) signaling exhibits multiple timescales of activity with classic slow signals related to brain and behavioral states and fast, phasic signals reflecting behavioral events, including movement, reinforcement and sensory-evoked responses. However, it remains unknown whether sensory cholinergic signals target the sensory cortex and how they relate to local functional topography. Here we used simultaneous two-channel, two-photon imaging of CBF axons and auditory cortical neurons to reveal that CBF axons send a robust, nonhabituating and stimulus-specific sensory signal to the auditory cortex. Individual axon segments exhibited heterogeneous but stable tuning to auditory stimuli allowing stimulus identity to be decoded from population activity. However, CBF axons displayed no tonotopy and their frequency tuning was uncoupled from that of nearby cortical neurons. Chemogenetic suppression revealed the auditory thalamus as a major source of auditory information to the CBF. Finally, slow fluctuations in cholinergic activity modulated the fast, sensory-evoked signals in the same axons, suggesting that a multiplexed combination of fast and slow signals is projected from the CBF to the auditory cortex. Taken together, our work demonstrates a noncanonical function of the CBF as a parallel channel for state-dependent sensory signaling to the sensory cortex that provides repeated representations of a broad range of sound stimuli at all points on the tonotopic map.

RESUMO

Rapid categorization of vocalizations enables adaptive behavior across species. While categorical perception is thought to arise in the neocortex, humans and other animals could benefit from functional organization of ethologically-relevant sounds at earlier stages in the auditory hierarchy. Here, we developed two-photon calcium imaging in the awake echolocating bat (Eptesicus fuscus) to study encoding of sound meaning in the Inferior Colliculus, which is as few as two synapses from the inner ear. Echolocating bats produce and interpret frequency sweep-based vocalizations for social communication and navigation. Auditory playback experiments demonstrated that individual neurons responded selectively to social or navigation calls, enabling robust population-level decoding across categories. Strikingly, category-selective neurons formed spatial clusters, independent of tonotopy within the IC. These findings support a revised view of categorical processing in which specified channels for ethologically-relevant sounds are spatially segregated early in the auditory hierarchy, enabling rapid subcortical organization of call meaning.

RESUMO

The mammalian superior colliculus (SC) and its non-mammalian homolog, the optic tectum are implicated in sensorimotor transformations. Historically, emphasis on visuomotor functions of the SC has led to a popular view that it operates as an oculomotor structure rather than a more general orienting structure. In this review, we consider comparative work on the SC/optic tectum, with a particular focus on non-visual sensing and orienting, which reveals a broader perspective on SC functions and their role in species-specific behaviors. We highlight several recent studies that consider ethological context and natural behaviors to advance knowledge of the SC as a site of multi-sensory integration and motor initiation in diverse species.
