The Rights of Children and Families: Local Initiatives in the Miami Valley

Dayton’s Committee on the Place-Based Two-Generation Approach to Poverty completed a working paper titled “A Call for Community Long-Term Recovery Plan” in January of 2021, arguing for an approach to recovery that is strategic, efficient, equity-focused, and regional. Practitioners and theorists connected to this document will address challenges and opportunities for addressing the rights of children in this area, particularly addressing the ways a regional approach can help to dismantle the legacy of historical injustices as we try to build back better

FABBRICAZIONE E RAFFREDDAMENTO DEL LINGOTTO A87 IN ACCIAIO F22+V

Il lingotto A87 in acciaio F22V è tra tutti i lingotti prodotti da ABS, quello che viene utilizzato per la realizzazione di grossi reattori per il campo petrolchimico. Date le dimensioni e la particolare composizione chimica che lo caratterizza, la produzione del lingotto A87 risulta particolarmente delicata. Infatti, gli acciai utilizzati nella produzione di reattori in campo petrolchimico devono essere in grado di sopportare carichi elevati in difficili condizioni operative, ambienti corrosivi ad alte temperature. Quindi, vanno tenuti sotto controllo tutti gli elementi della chimica che possono produrre iinfragilimenti del materiale ad alta temperatura, motivo per il quale vanno tenuti sotto controllo il J e l’X factor. Inoltre, data la mole del lingotto, risulta molto importante controllare sia il tenore di idrogeno nella chimica dell’acciaio, per evitare i difetti per fiocchi, che gli elementi che hanno maggiore tendenza alla segregazione per tenere quanto più possibile omogenea la composizione chimica tra le varie parti del lingotto. In questo articolo vengono descritte le principali problematiche connesse al raffreddamento del lingotto in cassone coibentato e viene presentato lo studio compiuto in collaborazione con il C. S. M. atto ad ridurre tali problematiche. Il processo di raffreddamento dei lingotti è caratterizzato dall’interazione non lineare tra il campo termico e meccanico, con l’ulteriore complicazione dovuta alla presenza della trasformazione di fase allo stato solido da austenite a ferrite e alla formazione di componenti microstrutturali, come perlite, bainite o martensite. Le proprietà finali del materiale, la distribuzione di tensioni residue e quindi l’insorgere di cricche sono fortemente dipendenti dalle reciproche interazioni tra questi aspetti

The effects of the spontaneous presence of a spouse/partner and others on cardiovascular reactions to an acute psychological challenge

The presence of supportive others has been associated with attenuated cardiovascular reactivity in the laboratory. The effects of the presence of a spouse and others in a more naturalistic setting have received little attention. Blood pressure and heart rate reactions to mental stress were recorded at home in 1028 married/partnered individuals. For 112 participants, their spouse/partner was present; for 78, at least one other person was present. Women tested with a spouse/partner present showed lower magnitude systolic blood pressure and heart rate reactivity than those tested without. Individuals tested with at least one nonspousal other present also displayed attenuated reactivity. This extends the results of laboratory studies and indicates that the spontaneous presence of others is associated with a reduction in cardiovascular reactivity in an everyday environment; spouse/partner presence would appear to be especially effective for women.\ud \u

Toward Common Data Elements for International Research in Long-term Care Homes: Advancing Person-Centered Care

To support person-centered, residential long-term care internationally, a consortium of researchers in medicine, nursing, behavioral, and social sciences from 21 geographically and economically diverse countries have launched the WE-THRIVE consortium to develop a common data infrastructure. WE-THRIVE aims to identify measurement domains that are internationally relevant, including in low-, middle-, and high-income countries, prioritize concepts to operationalize domains, and specify a set of data elements to measure concepts that can be used across studies for data sharing and comparisons. This article reports findings from consortium meetings at the 2016 meeting of the Gerontological Society of America and the 2017 meeting of the International Association of Gerontology and Geriatrics, to identify domains and prioritize concepts, following best practices to identify common data elements (CDEs) that were developed through the US National Institutes of Health/National Institute of Nursing Research's CDEs initiative. Four domains were identified, including organizational context, workforce and staffing, person-centered care, and care outcomes. Using a nominal group process, WE-THRIVE prioritized 21 concepts across the 4 domains. Several concepts showed similarity to existing measurement structures, whereas others differed. Conceptual similarity (convergence; eg, concepts in the care outcomes domain of functional level and harm-free care) provides further support of the critical foundational work in LTC measurement endorsed and implemented by regulatory bodies. Different concepts (divergence; eg, concepts in the person-centered care domain of knowing the person and what matters most to the person) highlights current gaps in measurement efforts and is consistent with WE-THRIVE's focus on supporting resilience and thriving for residents, family, and staff. In alignment with the World Health Organization's call for comparative measurement work for health systems change, WE-THRIVE's work to date highlights the benefits of engaging with diverse LTC researchers, including those in low-, middle-, and high-income countries, to develop a measurement infrastructure that integrates the aspirations of person-centered LTC

Quantification of very low-abundant proteins in bacteria using the HaloTag and epi-fluorescence microscopy.

Cell biology is increasingly dependent on quantitative methods resulting in the need for microscopic labelling technologies that are highly sensitive and specific. Whilst the use of fluorescent proteins has led to major advances, they also suffer from their relatively low brightness and photo-stability, making the detection of very low abundance proteins using fluorescent protein-based methods challenging. Here, we characterize the use of the self-labelling protein tag called HaloTag, in conjunction with an organic fluorescent dye, to label and accurately count endogenous proteins present in very low numbers (<7) in individual Escherichia coli cells. This procedure can be used to detect single molecules in fixed cells with conventional epifluorescence illumination and a standard microscope. We show that the detection efficiency of proteins labelled with the HaloTag is ≥80%, which is on par or better than previous techniques. Therefore, this method offers a simple and attractive alternative to current procedures to detect low abundance molecules

Realistic constraints on the doubly charged bilepton couplings from Bhabha scattering with LEP data

Upper limits on doubly charged bilepton couplings and masses are extracted from LEP data for Bhabha scattering at energy range $\sqrt{s}=183-202$ GeV using standard model program ZFITTER which calculates radiative corrections. We find that $g_{L}^{2}/M_{L}^{2}<O(10^{-5})GeV^{-2}$ at 95% C.L. for scalar and vector bileptons.Comment: 5 pages, 1 EPS figur

Life events and hemodynamic stress reactivity in the middle-aged and elderly

Recent versions of the reactivity hypothesis, which consider it to be the product of stress exposure and exaggerated haemodynamic reactions to stress that confers cardiovascular disease risk, assume that reactivity is independent of the experience of stressful life events. This assumption was tested in two substantial cohorts, one middle-aged and one elderly. Participants had to indicate from a list of major stressful life events up to six they had experienced in the previous two years. They were also asked to rate how disruptive and stressful they were, at the time of occurrence and now. Blood pressure and pulse rate were measured at rest and in response to acute mental stress. Those who rated the events as highly disruptive at the time of exposure and currently exhibited blunted systolic blood pressure reactions to acute stress. The present results suggest that acute stress reactivity may not be independent of stressful life events experience
