Positioning Social Work Researchers for Engaged Scholarship to Promote Public Impact
Creators: name: Jensen, Todd M.

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: The concept of engaged scholarship has garnered significant attention across numerous scientific disciplines. Engaged scholarship can be conceptualized as both a method centered on cocreating and applying new knowledge and a movement focused on prioritizing community identification of needs and social problem-solving strategies. In an effort to position social work researchers for engaged scholarship to promote public impact, we provide an overview of the following engaged-scholarship mechanisms: (a) community-based participatory research, (b) participatory action research, (c) practice-based research networks, (d) translational research, (e) transdisciplinary scientific collaborations, (f) systemic evaluation, and (g) developmental evaluation. We address the contextual factors that may influence the extent to which social work researchers can successfully pursue engaged scholarship and conclude by explicating a plausible relationship between engaged scholarship and public impact scholarship. Specifically, we apply the diffusion of innovations model and community dissonance theory to conceptually position engaged scholarship as a vehicle for promoting and optimizing public impact scholarship.

description: In this paper we study the thermodynamics of a crystalline solid by applying q-deformed algebra of Fibonacci oscillators through the generalized Fibonacci sequence of two real and independent deformation parameters q1 and q2. We find a (q1, q2)-deformed Hamiltonian and consequently the q-deformed thermodynamic quantities. The results led us to interpret the deformation parameters acting as disturbance or impurities factors modifying the characteristics of a crystal structure. More specifically, we found the possibility of adjusting the Fibonacci oscillators to describe the change of thermal conductivity of a given element as one inserts impurities.

description: We present the analysis of Blazhko-type modulation in double-mode RR Lyrae (RRd) stars found in the OGLE photometry of the Galactic bulge. Modulation is detected in 15 stars. Most of them have non-typical period ratio of the radial modes. In the Petersen diagram, at a given period of the fundamental mode, they are located significantly below or above the sequence formed by the majority of RRd stars. Multi-periodic modulation is very frequent; two or three modulation periods are detected in 8 stars. Modulation periods vary from ~20 to more than 300 days. Radial mode amplitudes can be modulated by a few to nearly hundred per cent. Both radial modes may be modulated with the same period. More commonly however, dominant modulation for the fundamental mode has different period than dominant modulation for the first overtone. Quite often modulation of only one mode is detected in the data. We find a clear feedback between pulsation amplitude of the dominant mode and mean stellar brightness: lower the pulsation amplitude, brighter the star. At phases of low pulsation amplitude, the mode periods are prone to fast changes. All the stars share the common feature: their pulsation properties are non-stationary. Amplitudes and phases of the radial modes vary irregularly on a long time-scale of a few hundred or thousand days. The short-term modulations are also irregular. One of the stars has switched the pulsation mode recently: from single-mode fundamental mode pulsation to RRd state. In other star the non-radial mode with characteristic ~0.61 period ratio to the first overtone is detected. This non-radial mode is likely modulated with the same period as the radial modes.

description: When quantum systems interact with the environment they lose their quantum properties, such as coherence. Quantum erasure makes it possible to restore coherence in a system by measuring its environment, but accessing the whole of it may be prohibitive: realistically one might have to concentrate only on an accessible subspace and neglect the rest. If that is the case, how good is quantum erasure? In this work we compute the largest coherence $\langle \mathcal C\rangle$ that we can expect to recover in a qubit, as a function of the dimension of the accessible and of the inaccessible subspaces of its environment. We then imagine the following game: we are given a uniformly random pure state of $n+1$ qubits and we are asked to compute the largest coherence that we can retrieve on one of them by optimally measuring a certain number $0\leq a\leq n$ of the others. We find a surprising effect around the value $a\approx n/2$: the recoverable coherence sharply transitions between 0 and 1, indicating that in order to restore full coherence on a qubit we need access to only half of its physical environment (or in terms of degrees of freedom to just the square root of them). Moreover, we find that the recoverable coherence becomes a typical property of the whole ensemble as $n$ grows.

description: The Gurarij operator space $\mathbb{NG}$ introduced by Oikhberg is the unique separable $1$-exact operator space that is approximately injective in the category of $1$-exact operator spaces and completely isometric linear maps. We prove that a separable operator space $X$ is nuclear if and only if there exist a linear complete isometry $φ:X\rightarrow \mathbb{NG}$ and a completely contractive projection from $\mathbb{NG}$ onto the range of $φ$. This can be seen as the operator space analog of Kirchberg's nuclear embedding theorem. We also establish the natural operator system analog of Kirchberg's nuclear embedding theorem involving the Gurarij operator system $\mathbb{GS}$.

description: There is a dearth of research on the evaluation of the psychometric performance of instruments designed to measure students’ generalist-level social work competencies. There is also uncertainty on the performance of various response option formats used to measure students’ competencies in assessment instruments. Using a sample of 198 master of social work students and 198 field instructors, the current study employs confirmatory factor analysis to assess the psychometric performance of a field evaluation instrument designed to measure students’ generalist-level social work competencies. The results provide evidence to support the validity and reliability of the instrument. The results also highlight nuances associated with a 5-point response option format for items used to measure competency indicators. Implications, limitations, and directions for future research are discussed.

description: Local environments and valence electron counts primarily determine the electronic states and physical properties of transition metal complexes. For example, square-planar surroundings found in transition oxometalates such as curprates are usually associated with the d8 or d9 electron configuration. In this work, we address an exotic square-planar mono-oxoanion [IrO4]^{4-} as observed in Na4IrO4 with Ir(IV) in d^5 configuration, and characterize the chemical bonding by experiment and ab initio calculations. We find that Na4IrO4 in its ground state evolves a square-planar coordination for Ir(IV) because of the weak Coulomb repulsion of Ir-5d electrons. In contrast, in its 3d counterpart, Na4CoO4, Co(IV) is in tetrahedral coordination, due to strong electron correlation. Na4IrO4 thus may serve as a simple paradigmatic platform for studying the ramifications of Hubbard type Coulomb interactions on local geometries.

description: Because of the potential stepparent-stepchild relationships have for tension and conflict, clinicians have identified the development of a positive stepparent-stepchild connection as one of the major tasks of stepfamily life. Stepparents often are advised to focus initially on developing friendships with stepchildren, or seeking affinity with them, particularly early in the life of the relationship. Both family systems theory and evolutionary theory suggest that stepparents’ affinity-seeking behaviors are related to the quality and functioning of other stepfamily dyads, such as couple relationships, and the whole stepfamily. We extend prior work on stepparents’ affinity seeking by including perceptions of both members of the stepcouple about affinity seeking, stepfather-stepchild conflicts, couple relationship quality, and stepfamily cohesion. Stepfathers and mothers from 234 stepcouples independently completed online surveys. After accounting for covariates (i.e., duration of mothers’ previous relationships, duration of the stepcouple relationship, focal child’s biological sex and age, number of children in the household, and mothers’ report of household income), stepfathers’ perceptions of affinity-seeking with the focal child significantly predicted both partners’ perceptions of stepfather-stepchild conflict, marital quality, marital confidence, and stepfamily cohesion. Mothers’ perceptions of stepfathers’ affinity-seeking were significantly related to her marital confidence and perceptions of stepfamily cohesion. Stepfathers’ perceptions of their affinity-seeking explained more variance in stepfathers’ and mothers’ outcomes than did mothers’ perceptions. The results suggest benefits associated with stepfather affinity-seeking—less conflict with stepchildren, better couple relationships, and closer stepfamily ties. Our findings provide evidence for encouraging stepparents to focus on building affinity with stepchildren.

description: Stepparent–child relationships and new couple relationships are core pillars of stepfamily functioning and well-being. Although research generally indicates that stepparent–child relationship quality and couple relationship quality are positively associated, questions remain about in which contexts and from whose perspective this association holds. Using reports from parents and stepparents in a sample of 291 stepfamily heterosexual couples, we assess whether stepfamily household type (i.e., mother–stepfather, father–stepmother) moderates the association between stepparent–child relationship quality and couple relationship quality. Results indicate that stepparent–child relationship quality and couple relationship quality are positively associated in both mother–stepfather and father–stepmother families, and from the vantage point of both parents and stepparents. The positive association is significantly larger in mother–stepfather families from the vantage point of stepfathers. Implications for future research and practice with stepfamilies are discussed.

A characterization of the class of sample points for which the theorem holds is given. Such points are given the name of Doob random points. It is shown that a point is Doob random if its tail is computably random in a certain sense. Moreover, Doob randomness is strictly weaker than computable randomness and is incomparable with Schnorr randomness.

description: Abstract The reported dataset addresses potential correlates and predictors of beliefs in conspiracy theories about the COVID-19 pandemic. Different psychological constructs (self-esteem, Dark Triad personality traits, collective narcissism, political attitude, individualism/collectivism), social status, and socio-demographic variables were assessed. Data from 746 participants from all parts of Germany who study part-time while working were collected between May 26 to July 5, 2020. We used a cross-sectional online survey comprising a total of 98 items. Preliminary analysis revealed sound psychometric properties of the measures. These data provide several opportunities for further use and can be utilized for research and educational purposes. For example, comparisons can be drawn between existing research on conspiracy theories to determine whether known factors determining beliefs in conspiracy theories are also relevant for COVID-19.

description: Stepfamilies are an increasingly common context in which adults and children reside. Past research has examined family processes that promote family resilience, such as dyadic relationships marked by warmth, positive communication, satisfaction, and closeness. What remains less clear is whether various profiles of dyadic relationship quality within stepfamilies exist and operate to influence stepfamily stability. Using data from the National Longitudinal Study of Adolescent to Adult Health, we conducted a latent profile analysis of mother-child, stepfather-child, and stepcouple relationship quality among a sample of 1,646 adolescents residing in married and cohabiting mother-stepfather families. Results favor a 4-profile solution, labeled high-quality, high-quality couple relationship, high-quality parent-child relationships, and low-quality. The identified latent profiles displayed differences with respect to family stability, or rates of remaining an intact family system 1 year later.

description: We investigate the relaxation behavior of thin films of a polyamide random copolymer, PA66/6I, with various film thicknesses using dielectric relaxation spectroscopy. Two dielectric signals are observed at high temperatures, the $α$-process and the relaxation process due to electrode polarization (the EP-process). The relaxation time of the EP-process has a Vogel-Fulcher-Tammann type of temperature dependence, and the glass transition temperature, $T_{\rm g}$, evaluated from the EP-process agrees very well with the $T_{\rm g}$ determined from the thermal measurements. The fragility index derived from the EP-process increases with decreasing film thickness. The relaxation time and the dielectric relaxation strength of the EP-process are described by a linear function of the film thickness $d$ for large values of $d$, which can be regarded as experimental evidence for the validity of attributing the observed signal to the EP-process. Furthermore, there is distinct deviation from this linear law for thicknesses smaller than a critical value. This deviation observed in thinner films is associated with an increase in the mobility and/or diffusion constant of the charge carriers responsible for the EP-process. The $α$-process is located in a high frequency region than the EP-process at high temperatures, but merges with the EP-process at lower temperatures near the glass transition region. The thickness dependence of the relaxation time of the $α$-process is different from that of the EP-process. This suggests that there is decoupling between the segmental motion of the polymers and the translational motion of the charge carriers in confinement.

description: Mesangial cells (MCs), substantial cells for architecture and function of the glomerular tuft, take a key role in progression of diabetic kidney disease (DKD). Despite long standing researches and the need for novel therapies, the underlying regulatory mechanisms in MCs are elusive. This applies in particular to long non-coding RNAs (lncRNA) but also microRNAs (miRNAs). In this study, we investigated the expression of nuclear paraspeckle assembly transcript 1 (NEAT1), a highly conserved lncRNA, in several diabetes in-vitro models using human MCs. These cells were treated with high glucose, TGFβ, TNAα, thapsigargin, or tunicamycin. We analyzed the implication of NEAT1 silencing on mesangial cell migration, proliferation, and cell size as well as on mRNA and miRNA expression. Here, the miRNA hsa-miR-339-5p was not only identified as a potential interaction partner for NEAT1 but also for several coding genes. Furthermore, overexpression of hsa-miR-339-5p leads to a MC phenotype comparable to a NEAT1 knockdown. In-silico analyses also underline a relevant role of NEAT1 and hsa-miR-339-5p in mesangial physiology, especially in the context of DKD.

We report an experiment on a superconductor-graphene double quantum dot (QD) system, in which we observe Cooper pair splitting (CPS) up to a CPS efficiency of ~ 10%. With bias on both QDs, we are able to detect a positive conductance correlation across the two distinctly decoupled QDs. Furthermore, with bias only on one QD, CPS and elastic co-tunneling can be distinguished by tuning the energy levels of the QDs to be asymmetric or symmetric with respect to the Fermi level in the superconductor.

description: To examine whether marital dynamics within remarried couples (in the form of perceived quality and confidence) or perceptions of stepparent–stepchild relationship quality were more strongly associated with stepfamily functioning. Stepfamilies are common in the United States, and identifying factors central to healthy stepfamily functioning is an important task. Some stepfamily clinicians contend that steprelationships may be more closely related to overall stepfamily functioning than remarriage quality, although empirical support for this assertion is limited. Heterosexual remarried couples (N = 291) responded to online surveys asking about marital quality, marital confidence, stepparent–stepchild relationship quality, and stepfamily functioning (i.e., stepfamily cohesion, expressiveness, and harmony). Data were analyzed using actor–partner interdependence modeling in a structural equation modeling framework. Marital dynamics were somewhat more strongly associated with stepfamily functioning than stepparent–stepchild relationship quality, although both were positively associated with stepfamily functioning. Confidence in the future of the marriage had a slightly stronger association with stepfamily functioning than did marital quality. Actor effects were more often statistically associated with stepfamily functioning than were partner effects for both stepparents and biological parents. Findings validate a family systems approach to strengthening stepfamily functioning by highlighting the joint and unique contributions of both marital dynamics and stepparent–stepchild relationship quality. Clinicians and educators working with stepfamilies should attend to both promoting positive, emotionally close steprelationships and strong marital bonds and confidence in higher order marriages.

description: In the vertebrate olfactory bulb, reciprocal dendrodendritic interactions between its principal neurons, the mitral and tufted cells, and inhibitory interneurons in the external plexiform layer mediate both recurrent and lateral inhibition, with the most numerous of these interneurons being granule cells. Here, we used recently established anatomical parameters and functional data on unitary synaptic transmission to simulate the strength of recurrent inhibition of mitral cells specifically from the reciprocal spines of rat olfactory bulb granule cells in a quantitative manner. Our functional data allowed us to derive a unitary synaptic conductance on the order of 0.2 nS. The simulations predicted that somatic voltage deflections by even proximal individual granule cell inputs are below the detection threshold and that attenuation with distance is roughly linear, with a passive length constant of 650 μm. However, since recurrent inhibition in the wake of a mitral cell action potential will originate from hundreds of reciprocal spines, the summated recurrent IPSP will be much larger, even though there will be substantial mutual shunting across the many inputs. Next, we updated and refined a preexisting model of connectivity within the entire rat olfactory bulb, first between pairs of mitral and granule cells, to estimate the likelihood and impact of recurrent inhibition depending on the distance between cells. Moreover, to characterize the substrate of lateral inhibition, we estimated the connectivity via granule cells between any two mitral cells or all the mitral cells that belong to a functional glomerular ensemble (i.e., which receive their input from the same glomerulus), again as a function of the distance between mitral cells and/or entire glomerular mitral cell ensembles. Our results predict the extent of the three regimes of anatomical connectivity between glomerular ensembles: high connectivity within a glomerular ensemble and across the first four rings of adjacent glomeruli, substantial connectivity to up to eleven glomeruli away, and negligible connectivity beyond. Finally, in a first attempt to estimate the functional strength of granule-cell mediated lateral inhibition, we combined this anatomical estimate with our above simulation results on attenuation with distance, resulting in slightly narrowed regimes of a functional impact compared to the anatomical connectivity.

description: Social work and other professions are endeavoring to promote student proficiency with respect to core competencies of the discipline, and the attainment of these competencies must be demonstrated objectively in some way. This article provides an illustrative guide for social work educators seeking to develop comprehensive examinations to assess students’ acquisition of professional competencies, particularly at the master’s level and across generalist and specialization levels of practice. An integrative framework is presented, highlighting 5 central stages of examination development: planning, creating and implementing, evaluating, revising, and perpetuating. These stages are illustrated with a case example, followed by key conclusions, methodological considerations, and other implications for moving forward on efforts to effectively develop examinations to measure student social work competencies.

description: When the predecoupling plasma is thermodynamically reversible its fluctuations are classified in terms of the adiabatic and entropic modes. A different category of physical solutions, so far unexplored, arises when the inhomogeneities of the viscosity coefficients induce computable curvature perturbations. The viscous modes are explicitly illustrated and compared with the conventional isocurvature solutions.

description: Viele Theorien über gewöhnliche Graphen wurden in den letzten Jahren aufsignierte Graphen erweitert. In den meisten dieser Theorien verhalten sich balancierte Teile ähnlich wie im nicht signierten Fall, während die unbalancierten Teile die Hauptursache für die Unterschiede im Vergleich zum nicht signierten Fall sind. Daher kann das Verständnis der Quelle der Unbalanciertheit eines signierten Graphen ein wichtiger Schritt sein, um ein besseres Verständnis zuerlangen. Im ersten Teil dieser Arbeit wird dies durch die Untersuchung der Kritikalität in Bezug auf den Frustrationsindex erreicht. Die kritisch k-frustrierten signierten Graphen werden charakterisiert und ihre strukturellen Eigenschaften werden untersucht. Wir definieren und charakterisieren eine spezielle Familie von kritisch k-frustrierten signierten Graphen, bei denen jedes Paar negativer Knoten gemeinsame Kanten hat. Außerdem beweisen wir, dass die Anzahl der nicht zerlegbaren und irreduziblen kritisch k-frustrierten signierten Graphen für k 3 endlich ist. Im zweiten Teil verallgemeinern wir alte Ansätze der Knotenfärbung signierter Graphen, wobei der starke Einfluss des unbalancierten Teils auf die Färbung deutlich wird. Weiterhin geben wir ein Ergebnis an, das den Frustrationsindex und unsere Definition der chromatischen Zahl in Beziehung setzt.
description: Many theories on ordinary graphs have been extended to signed graphs in the last years. In most of them, balanced parts behave similarly to the unsigned case, while the unbalanced parts are the main source of the differences with respect to the unsigned case. Therefore, understanding the source of unbalance of a signed graph may be a key step to get a better understanding. In the first part of this work, this is done by studying criticality with respect to the frustration index. The critically k-frustrated signed graphs are characterized and their structural properties are studied. We define and characterize a special family of critically k-frustrated signed graphs where each pair of negative circuits share edges. Moreover, we prove that the number of non-decomposable and irreducible critically k-frustrated signed graphs, for k 3, is finite. In the second part, we generalize old approaches of vertex-coloring of signed graphs, where the strong influence of the unbalance parts on the coloring can be seen, and we give a result relating frustration index and our definition of chromatic number.

description: The dynamic mechanism of the Thomas-Ehrman shift is studied in three-cluster systems by example of $^{16}$Ne and $^{16}$C isobaric mirror partners. We predict configuration mixings for $0^+$ and $2^+$ states in $^{16}$Ne and $^{16}$C. Large isospin symmetry breaking on the level of wave function component weights is demonstrated for these states and discussed as three-body mechanism of Thomas-Ehrman shift. It is shown that the description of the Coulomb displacement energies requires a consistency among three parameters: the $^{16}$Ne decay energy $E_T$, the $^{15}$F ground state energy $E_r$, and the configuration mixing parameters for the $^{16}$Ne/$^{16}$C $0^+$ and $2^+$ states. Basing on this analysis we infer the $^{15}$F $1/2^+$ ground state energy to be $E_r=1.39-1.42$ MeV.

description: Chronic psychosocial stress participates prominently in the etiology of various psychiatric conditions and comorbid somatic pathologies; however, suitable pharmacotherapy of these disorders is still of high medical need. During the last few decades, research on mGlu receptors advanced remarkably and much attention was given to the mGlu7 subtype. Here, genetic mGlu7 ablation, short-term pharmacological mGlu7 blockade, as well as siRNA-mediated knockdown of mGlu7 were shown to result in an acute anti-stress, antidepressant- and anxiolytic-like phenotype in mice. Moreover, we recently revealed a prominent stress-protective effect of genetic mGlu7 ablation also with respect to chronic psychosocial stress. In addition, we are able to demonstrate in the present study that the chronic pharmacological blockade of mGlu7 interferes with various chronic stress-induced alterations. For this, we used the chronic subordinate colony housing (CSC), a mouse model of chronic male subordination, in combination with chronic treatment with the mGlu7-selective orthosteric-like antagonist XAP044 (7-hydroxy-3-(4-iodophenoxy)-4H-chromen-4-one). Interestingly, XAP044 dose-dependently ameliorates hypothalamic–pituitary–adrenal axis dysfunctions, thymus atrophy, as well as the CSC-induced increase in innate anxiety. Taken together, our findings provide further evidence for the role of mGlu7 in chronic psychosocial stress-induced alterations and suggests the pharmacological blockade of mGlu7 as a promising therapeutic approach for the treatment of chronic stress-related pathologies in men

description: Social work doctoral education can prepare students to become research scholars whose work has impact by providing and promoting the development of an appropriately sophisticated and diverse research methods tool kit. Students can cultivate their tool kits through course work, mentored research experience, and specialized workshops. The tool kit is best grounded in guided reading of methodological texts—that is, reading methodological texts while conferring with advanced peers, faculty, and research supervisors—which provides essential teaching and experiences to enhance understanding and use. This article lays out a rationale for guided reading and provides an example of primer text and recommended readings to support guided reading for one set of related research methods: randomized experimentation and finite mixture modeling.

description: The Axelrod model for the dissemination of culture exhibits a rich spatial distribution of cultural domains, which depends on the values of the two model parameters: $F$, the number of cultural features and $q$, the common number of states each feature can assume. In the one-dimensional model with $F=q=2$, which is closely related to the constrained voter model, Monte Carlo simulations indicate the existence of multicultural absorbing configurations in which at least one macroscopic domain coexist with a multitude of microscopic ones in the thermodynamic limit. However, rigorous analytical results for the infinite system starting from the configuration where all cultures are equally likely show convergence to only monocultural or consensus configurations. Here we show that this disagreement is due simply to the order that the time-asymptotic limit and the thermodynamic limit are taken in the simulations. In addition, we show how the consensus-only result can be derived using Monte Carlo simulations of finite chains.

description: The TRIM-NHL protein Meiotic P26 (Mei-P26) acts as a regulator of cell fate in Drosophila. Its activity is critical for ovarian germline stem cell maintenance, differentiation of oocytes, and spermatogenesis. Mei-P26 functions as a post-transcriptional regulator of gene expression; however, the molecular details of how its NHL domain selectively recognizes and regulates its mRNA targets have remained elusive. Here, we present the crystal structure of the Mei-P26 NHL domain at 1.6 Å resolution and identify key amino acids that confer substrate specificity and distinguish Mei-P26 from closely related TRIM-NHL proteins. Furthermore, we identify mRNA targets of Mei-P26 in cultured Drosophila cells and show that Mei-P26 can act as either a repressor or activator of gene expression on different RNA targets. Our work reveals the molecular basis of RNA recognition by Mei-P26 and the fundamental functional differences between otherwise very similar TRIM-NHL proteins.

description: Central European grasslands, such as calcareous grasslands and oat-grass meadows, are characterized by diverse environmental conditions and management regimes. Therefore, we aimed to determine potential differences in genetic and epigenetic variation patterns between the contrasting habitats and to identify the drivers of genetic and epigenetic variation. We investigated the genetic and epigenetic variation of the ecologically variable plant species Trifolium pratense L. applying amplified fragment length polymorphism and methylation-sensitive amplification polymorphism analyses. We observed low levels of genetic and epigenetic differentiation among populations and between habitat types. Genetic and epigenetic variations were not interdependent. Thus, genetic variation was significantly isolated by habitat dissimilarity, whereas epigenetic variation was affected by environment. More specifically, we observed a significant correlation of epigenetic diversity with soil moisture and soil pH (the latter potentially resulting in phosphorus limitation). Genetic variation was, therefore, affected more strongly by habitat-specific environmental conditions induced by land use-related disturbance and gene flow patterns, while epigenetic variation was driven by challenging environmental conditions.
