Show morePeople considering disclosure of their mental illness in the workplace have tonavigate a complex set of competing pressures to arrive at a disclosure decision. Existingmodels of disclosure fail to adequately consider the role of stigma, cannot be adequatelytested with measures currently in existence, and tend to ask participants about disclosureretrospectively. These limitations were addressed using a new path model which employsmeasures currently in existence, includes stigma, and assesses disclosure motivation inindividuals who have not disclosed at work. A national sample of 365 participants wererecruited using Amazon’s Mechanical Turk Marketplace (MTurk). While thehypothesized model achieved poor fit, important findings from the models tested hereprovide clear direction for future research.

Show moreThe recent transition to the Common Core State Standards for Mathematics is in line with current initiatives to improve mathematics teaching and learning through the emphasis of conceptual understanding and mathematical reasoning. Much research has been done on how to develop conceptual understanding for students in kindergarten through twelfth grade. Stein, Engle, Smith, & Hughes (2008) highlighted the importance of orchestrating productive classroom discussions. They suggest that this goal can be attained through the process of five steps, each depending on the previous step. Teachers must anticipate student responses to a task that will be taught, monitor student thinking as they are engaged in the task, purposefully select students to present based on their choice of representations, sequence those representations in a purposeful way, and then make connections among the representations so that students are able to understand key concepts. The first step in this process, anticipating student responses (ASR), is an area where little research has been done. The literature suggests that teachers that engaged in professional learning related to the practice did so at varying levels (Empson et al., 2017), and could develop those skills over time with explicit feedback (Popovic, Morrissey, & Kartal, 2018). However, research on average middle school mathematics teachers, those that were not enrolled in any professional learning focused on ASR, was absent from the literature. This study aimed to understand middle school mathematics teachers’ anticipation of student responses. A sample of 19 eighth grade math teachers that represented a variety of years of experience and curriculum use (traditional, reform, and teacher-developed) participated in semi-structured interviews and completed four common eighth grade math problems focused on the content of linear relationships and systems. Teachers’ anticipated student strategies were categorized as showing robust, moderate, limited, or lacking evidence of ASR. Based on the results, all of the teachers fit into one of four categories: those that anticipated student responses at (1) consistently high levels, (2) mixed levels, (3) consistently low levels, and (4) inconsistent levels. The results of this study found teachers who anticipated student responses at consistently high levels were experienced (over 10 years of experience), had numerous student-centered professional development experiences, considered their teacher-role as that of a facilitator, and had high expectations for students. They differed with respect to the type of curriculum they used, the certification they held, and the level of detail in their planning practices. Several of the teachers inconsistently anticipated student responses, providing robust and limited evidence for at least one problem. This speaks to the specialized knowledge that teachers have, what Hill and Charalambous (2012a) refer to as local mathematical knowledge for teaching. Among all of the variables considered, curriculum use did not appear to have an impact on teachers’ skills and knowledge related to anticipating student responses, although teachers used their curriculum materials in very different ways. Years of experience, secondary licensure, a student-centered philosophy of teaching, and teachers that described their role as that of a facilitator related to evidence of anticipating student responses. Understanding the variables that may impact teachers’ abilities to anticipate student responses, the first of five steps outlined by Stein et al. (2008), is important for supporting teachers as they orchestrate productive classroom discussions around important concepts.

Show moreResearch on Seasonal Affective Disorder (SAD) has produced several etiologicalmodels of SAD symptomatology, including a common cause model that conceptualizessymptoms as the result of a single underlying disease process, and the Dual VulnerabilityModel (Young et al., 1991) which posits that psychological symptoms of depressionfollow the onset of vegetative symptoms (e.g. hypersomnia, increased appetite) inindividuals with a vulnerability to seasonal changes. Studies of the structure of SADsymptomatology have been limited in their ability to evaluate these models. This studyused exploratory factor analysis and network analysis to examine baseline winter SADsymptoms (using a modified BDI-II) in 177 adults participating in a randomizedcontrolled trial of light treatment and CBT for SAD (Rohan et al., 2015). The factoranalysis supported a four-factor model that included negative cognition/affect, loss ofvitality, dysregulation, and increases in weight/appetite. The complex network model ofSAD conceptualized the network as a system of interacting symptoms. Results of thenetwork model paralleled those of the factor analysis in producing four communities ofinter-correlated symptoms. In addition to the full symptom network, a directed acyclicgraph was constructed to model causal relations between symptoms. Results suggest thatvegetative symptoms (loss of vitality and appetite/weight) lead ultimately to cognitivesymptoms, with intermediate effects of dysregulation symptoms. This partially supportsthe Dual Vulnerability model. Findings from the factor analysis and the network analysisare compared, and their implications for and treatment of SAD is discussed.

Show moreRecent epidemiology evidence suggests that vehicle emissions are major contributors to poor urban air quality. Human exposure to elevated concentration of traffic emissions has been associated with increased risk factors for a range of negative health outcomes. Evaluation of human exposure to vehicle emissions (e.g. ultrafine particles) mainly relies on dispersion models. Consequently, dispersion models need to comply with constantly increasing requirements to provide predictions of pollutant concentration. The dynamic of near roadway dispersion process needs to be investigated since most of the existing models does not account traffic condition variability (e.g. vehicle type and mode of operation) for dispersion. A five-year long field study was conducted to characterize dispersion near roadway with various vehicle mode of operation and vehicle type. To better understand the dispersion process near roadway, the impact of different ambient background categories (e.g. remote, lake, urban, industrial) on ultrafine particles (UFPs) need to be evaluated. Results demonstrate that each category has a different average ambient background concentration (pt cm–3) as follows: remote, 2,700; lake, 6,000; industrial 12,000 and urban 11,000. The large variations exist in ambient background concentration will result in significant variations in near roadway concentrations. The total near roadway measurements are generally near 20,000 pt cm–3 and reach to 60,000 pt cm–3 depending on the background and traffic emission. The dispersion near the roadway is also investigated in this study. A roadway restricted to light-duty vehicles (LDVs) was selected to conducted near roadway field measurement. Results indicate that the dispersion induced by vehicles is a two-stage process. When under the unsteady-state condition with small number of operating vehicles, the rate of dispersion near roadway increased from 2 m2 s-1 to 6 m2 s-1 as the number of vehicles increased. For steady-state condition, the rate of dispersion was constant near 6 m2 s-1 and not increased with additional vehicles. For a roadway mixed with both LDVs and heavy duty vehicles (HDVs), similar results were found. Dispersion increased from 6 to 18 m2 s-1 as total vehicle flow rate increased to 10,000 veh h-1 and HDV flow rate increased to 1000 veh h-1. Finally, the calculated dispersion near roadway is used to estimate the UFP emission factors. The UFP emission factors were ranged from 0.5 × 1013 to 1.5 × 1013 pt km-1 veh-1 and from 7 × 1014 to 20 × 1014 pt km-1 veh-1 for LDVs and HDVs, respectively. The variations in UFP emission factors are due to change in vehicle mode of operation.The results from this study will be critical for parameterization of dispersion near roadway and provide important emission inventory for interdisciplinary partnership among different fields (e.g. air quality, transportation design and urban planning) in solving transportation air quality problem.

Show moreIndividuals with high marital satisfaction tend to have better health and engage in healthier behaviors than those with low marital satisfaction. Multiple studies have explored satisfaction-health associations for married individuals in proximal relationships (PR), but no known study has tested these associations for married individuals in long distance relationships (LDR). LDR is a relationship arrangement that challenges traditional conceptions of romantic relationships and physical closeness. Related, recent empirical work indicates marital satisfaction-health associations may be weaker in LDR than PR due to unique relational and individual factors. The current study tested whether marital satisfaction-health associations are moderated by relational proximity (i.e. LDR vs. PR). We used an adult, married sample of individuals in LDR and PR (N=293) who completed an online survey on relationships and health. Unexpectedly, moderation results suggested that associations between marital satisfaction and health did not differ by relational proximity. One potential difference emerged: Marital satisfaction was associated with satisfaction with functioning for those in PR, but not LDR. Overall, study findings challenge recent empirical work reporting between-group, relationship-health differences between PR and LDR. Clinicians can utilize our findings to improve treatment for couples and families in LDR. Future research should utilize actor-partner interdependence models and longitudinal studies to further elucidate the associations between marital satisfaction and health for individuals in this unique but increasingly prevalent relationship arrangement.

Show moreObjective Impact of a peer navigator program (PNP) develop by a community based participatory research team was examined on African Americans with serious mental illness who were homeless. Methods Research participants were randomized to PNP or a treatment-as-usual control group for one year. Data on physical and mental health, recovery, and quality of life were collected at baseline, 4, 8 and 12 months. Results Findings from group by trial ANOVAs of omnibus measures of the four constructs showed significant impact over the one year for participants in PNP compared to control described by small to moderate effect sizes. These differences emerged even though both groups showed significant improvements in reduced homelessness and insurance coverage. Conclusions Implications for improving in-the-field health care for this population are discussed. Whether these results occurred because navigators were peers per se needs to be examined in future research.

Show moreThe present study is to determine the Frank-Kasper phases in the Co-Nb-Ni system. Frank-Kasper phases, also called topological close packed (TCP) phases are one of the largest groups of intermetallic compounds. They are classified into several phases: A15, Laves, σ, µ and the M, P, R phases. In the 1200°C-isothermal section of the Co-Nb-Ni system, the µ phase and Laves phases exist over large composition ranges. In this study, the Co-Nb-Ni ternary system was investigated using optical microscopy(OM), X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS) and differential scanning calorimetry (DSC). The experimental results were compared with literature data and thermodynamic calculations. XRD was used to identify the Frank-Kasper phases. In comparison with previous investigations, the large extensition of µ phase in the Co-Nb-Ni system was verified. In addition, the small phase (~67at. % Nb) shown in the alloys with ~50at. % Nb is the unstablized impurity phase. On the other hand, according to the results of experiments and thermo-calc, C15 phase was found instead of C14 phase compared with Gupta's study.
