Community scholars increasingly focus on the linkage between residents’ sense of cohesion with the neighborhood and their own social networks in the neighborhood. A challenge is that whereas some ...research only focuses on residents’ social ties with fellow neighbors, such an approach misses out on the larger constellation of individuals’ relationships and the spatial distribution of those relationships. Using data from the Twin Communities Network Study, the current project is one of the first studies to examine the actual spatial distribution of respondents’ networks for a variety of relationships and the consequences of these for neighborhood and city cohesion. We also examine how a perceived structural measure of cohesion—triangle degree—impacts their perceptions of neighborhood and city cohesion. Our findings suggest that perceptions of cohesion within the neighborhood and the city depend on the number of neighborhood safety contacts as well as on the types of people with which they discuss important matters. On the other hand, kin and social friendship ties do not impact cohesion. A key finding is that residents who report more spatially dispersed networks for certain types of ties report lower levels of neighborhood and city cohesion. Residents with higher triangle degree within their neighborhood safety networks perceived more neighborhood cohesion.
The ADMX collaboration gathered data for its Run 1A axion dark matter search from January to June 2017, scanning with an axion haloscope over the frequency range 645-680 MHz (2.66-2.81 μeV in axion ...mass) at DFSZ sensitivity. The resulting axion search found no axion-like signals comprising all the dark matter in the form of a virialized galactic halo over the entire frequency range, implying lower bound exclusion limits at or below DFSZ coupling at the 90% confidence level. This paper presents expanded details of the axion search analysis of Run 1A, including review of relevant experimental systems, data-taking operations, preparation and interpretation of raw data, axion search methodology, candidate handling, and final axion limits.
Results are mixed for relationship education (RE) interventions with low‐income couples. For couples who experienced positive changes, it is not clear what aspects of program models contributed to ...change. Many low‐income couples attend government‐funded RE with limited access to social and community resources. Program models often provide related resources complimentary to RE skill‐building. We examined the relationship between income, social support, and family functioning for low‐income, ethnically diverse couples (N = 856) who attended RE, as well as the mediating effects of social support on family functioning outcomes. Analyses included three separate dyadic models that examined associations among constructs at baseline and immediately following the RE intervention. Results demonstrated relationships between participants’ reported social support and family functioning such that (a) social support was associated with baseline family functioning for both men and women; (b) men’s baseline social support was influenced by women’s baseline family functioning; and (c) men’s and women’s social support change score had a positive influence on their own family functioning change score. However, social support was not a significant mediator of change in family functioning. Implications for RE practice and research are also discussed.
RESUMEN
Los resultados de las intervenciones sobre educación para las relaciones (ER) con parejas de bajos recursos son variados. En el caso de las parejas que tuvieron cambios positivos, no está claro qué aspectos de los modelos del programa contribuyeron al cambio. Muchas parejas de bajos recursos asisten a ER financiadas por el gobierno con acceso limitado a recursos sociales y comunitarios. Los modelos del programa generalmente proporcionan recursos relacionados complementarios al desarrollo de habilidades para la ER. Analizamos la relación entre los ingresos, el apoyo social y el funcionamiento familiar en las parejas de bajos recursos y étnicamente diversas (N = 856) que asistieron a la ER, así como los efectos mediadores del apoyo social en los resultados del funcionamiento familiar. Los análisis incluyeron tres modelos diádicos independientes que examinaron las asociaciones entre los constructos al inicio del estudio e inmediatamente después de la intervención sobre ER. Los resultados demostraron las relaciones entre el apoyo social informado por los participantes y el funcionamiento familiar, por lo que (a) el apoyo social estuvo asociado con el funcionamiento familiar al inicio del estudio tanto en los hombres como en las mujeres; (b) el apoyo social de los hombres al inicio del estudio estuvo influenciado por el funcionamiento familiar de las mujeres al inicio del estudio; y (c) el puntaje de cambio del apoyo social de los hombres y las mujeres tuvo una influencia positiva en su propio puntaje de cambio del funcionamiento familiar. Sin embargo, el apoyo social no fue un mediador de cambio significativo en el funcionamiento familiar. También se debaten las implicancias para la investigación y la práctica en RE.
摘要
低收入伴侣的关系教育（RE）干预的结果有好也有坏。对于经历了积极变化的伴侣而言，项目模型的哪些方面起到了积极促进变化的作用尚不清楚。很多低收入的伴侣参加政府资助的关系教育，同时对社会和社区的支持等方面的资源获取和利用却十分有限。项目模型通常提供了相关的资源来补充关系教育中的具体技巧训练。本文研究的是收入，社会支持，家庭功能三者之间的关系，也研究社会支持对家庭功能结果的调和作用。研究对象为参加关系教育的856对低收入伴侣，来自多种族。分析包括三个独立的二元模型，用于研究相关的处在在基线的元素之间的关联性，和也包括立刻跟踪关系教育干预的结果。研究结果显示参与者报告的社会支持和家庭功能之间的关系表现在：(a) 社会支持和和男性、女性的基线家庭功能都有相关性； (b) 男性基线社会支持受女性基线家庭功能影响; (c) 男性和女性的社会支持变化分数对他们自身的家庭功能变化分数有积极影响。 但是社会支持并不是家庭功能变化的重要调节因素。关系教育如何实施和相关研究在研究启示部分有所讨论。
Introduction: The development and application of new molecular diagnostic assays based on next-generation sequencing and proteomics require improved methodologies for procurement of target cells from ...histological sections. Laser microdissection can successfully isolate distinct cells from tissue specimens based on visual selection for many research and clinical applications. However, this can be a daunting task when a large number of cells are required for molecular analysis or when a sizeable number of specimens need to be evaluated. Materials and Methods: To improve the efficiency of the cellular identification process, we describe a microdissection workflow that leverages recently developed and open source image analysis algorithms referred to as computer-aided laser dissection (CALD). CALD permits a computer algorithm to identify the cells of interest and drive the dissection process. Results: We describe several “use cases” that demonstrate the integration of image analytic tools probabilistic pairwise Markov model, ImageJ, spatially invariant vector quantization (SIVQ), and eSeg onto the ThermoFisher Scientific ArcturusXT and Leica LMD7000 microdissection platforms. Conclusions: The CALD methodology demonstrates the integration of image analysis tools with the microdissection workflow and shows the potential impact to clinical and life science applications.
We present a spectral phase unwrapping approach for grating-based differential phase-contrast data where the unwrapped interferometer phase shift is estimated from energy discriminated measurements ...using maximum likelihood principles. We demonstrate the method on tomographic data sets of a test specimen taken at different x-ray energies using synchrotron radiation. The proposed unwrapping technique was demonstrated to successfully correct the data set for phase wrapping.
