Gregory Research Beliefs Scale: Factor Structure and Psychometric Properties

Indiana University-Purdue University Indianapolis (IUPUI)GREGORY RESEARCH BELIEFS SCALE: FACTOR STRUCTURE AND PSYCHOMETRIC PROPERTIES The study at hand involves developing the Gregory Research Beliefs Scale (GRBS) to reliably and validly measure social work students’ beliefs about the function of research in social work practice. Research has considerable actual and potential benefits for practice. Social work students’ beliefs about this construct are vital. A description of the advantages of using research to inform practice is given. Additionally, the Council on Social Work Education and National Association of Social Workers’ policies that mandate the merger of research and practice are also provided to further justify the need for adequate psychometric evaluation of the construct. Details of the literature search strategy are described and critical evaluations of the empirical articles are conducted. Based on critical evaluations of instruments which have previously measured the same construct, a number of psychometric shortcomings are outlined to validate the need for further scale development of the construct. The present study’s objectives were to develop a scale which has an empirically and theoretically supported factor structure, acceptable coefficient alpha levels, empirically supported discriminant (divergent) validity, concurrent criterion validity, and known–groups criterion validity. Steps for developing the GRBS’s items, response format, sample, research design, and statistical tests are specified and conducted to determine the factor structure and psychometric properties. Finally, the strengths, limitations, and areas for future research are discussed

Online psychoeducation with parent management training: Examining the contribution of peer support

Psychoeducation is an empirically based intervention that is increasingly delivered online to individuals and groups. Low participation has been a problem for online designs that include peer support. New technology designs have been called for, and in response, we developed a model that synchronized the delivery of individual and group-based psychoeducational activities for parent management training. We used a problem-based learning strategy delivered to caregivers of youth demonstrating oppositional behaviours to encourage the development of helping processes and peer support. This mixed methods intervention study had high rates of participant retention and positive measurable changes for two of its three psychoeducational outcome measures. When we merged the study data, we observed that mutual aid—a frequently sought goal of group-based interventions—contributed to participant outcomes

A critical review of theory in social work journals: A replication study

Abstract: The purpose of this paper is multifold. Key aspects discussed include exploring the extent of theory discussion and progression in social work journals for the year 2004; discussing the necessity of theory in social work research and practice; reviewing previous research literature regarding evaluation of theory discussion and progression; proposing criteria for defining theory in social work journals; and presenting findings from the current study concerning theory discussion and progression in social work journals. Results: Of the 1,168 articles reviewed from 37 journals, 71 (approximately 6%) met the criteria for theory development with empirical base. Thus, a minimal number of articles (3 out of 71 or 4.2%) evaluated, based on the criteria in the theory quality scale (Table 1), received high quality ratings. Conclusion: Based on the results yielded by the analysis, we assert that social workers need to make a conscious effort to include theory in practice decisions. Keywords: Theory, social work theory, empirical assessment of theory, social work practice, theory progression, human behavior, and the social environment (HBSE

Data Recovery Investigations: Murvaul Creek Site (41PN175), Panola County, Texas

This report summarizes the archeological findings of the 2011 data recovery investigations at the Murvaul Creek site, 41PN175, in far northeastern Texas in Panola County. The site is located along Farm-to-Market Road (FM) 10 approximately 1 mile north of Gary, Texas (Figure 1). Geo-Marine, Inc. (GMI), performed this work under contract to the Texas Department of Transportation, Environmental Affairs Division (TxDOT ENV) under the Texas Antiquities Permit Number 5879 (Work Authorization [WA] 579 06 SA005; WA 590 08 SA005; CSJ:1222-01-014; Geo-Marine project numbers 22005.00.06 and 22005.00.09). The fieldwork for this project was conducted in advance of the planned widening of FM 10 that was to replace three bridges and a culvert over Murvaul Creek with a larger structure and shift the road approximately 26 meters (m; 85 feet [ft]) to the east. Since the planned improvements of FM 10 would result in the loss of information at the Murvaul Creek site—a site that was recommended eligible for inclusion in the National Register of Historic Places (NRHP) and for designation as a State Antiquities Landmark (SAL; formerly State Archeological Landmark)—the current data recovery investigations were initiated. The data recovery investigations were conducted between February 7, 2011, and April 3, 2011. During this period, the fieldwork was conducted in several stages: site clearing, geophysical survey, 50-x-50-centimeter (cm) excavations, block excavations, and mechanical site scraping. With the exception of the site clearing stage, the results of each of the fieldwork stages are reviewed individually in this report. The investigations resulted in the documentation of numerous features that appeared to have been the remains of a small Middle-to-Late Caddo settlement or farmstead situated on the edge of an interfluve south of the Murvaul Creek floodplain. Additionally, materials pertaining to the Archaic period were documented across the site. Although the site has been intensively studied within the TxDOT right-of-way (ROW), both the current investigations and previous work were limited to the ROW (cf. Cliff and Perttula 2002). Hence, the site is very likely larger than has been adequately documented

of the Moravian Karst Protected Landscape Area

Abstract Host traits and phylogeny can determine infection risk by driving pathogen transmission and its ability to infect new hosts. Predicting such risks is critical when designing disease mitigation strategies, and especially as regards wildlife, where intensive management is often advocated or prevented by economic and/or practical reasons. We investigated Pseudogymnoascus [Geomyces] destructans infection, the cause of white-nose syndrome (WNS), in relation to chiropteran ecology, behaviour and phylogenetics. While this fungus has caused devastating declines in North American bat populations, there have been no apparent population changes attributable to the disease in Europe. We screened 276 bats of 15 species from hibernacula in the Czech Republic over 2012 and 2013, and provided histopathological evidence for 11 European species positive for WNS. With the exception of Myotis myotis, the other ten species are all new reports for WNS in Europe. Of these, M. emarginatus, Eptesicus nilssonii, Rhinolophus hipposideros, Barbastella barbastellus and Plecotus auritus are new to the list of P. destructans-infected bat species. While the infected species are all statistically phylogenetically related, WNS affects bats from two suborders. These are ecologically diverse and adopt a wide range of hibernating strategies. Occurrence of WNS in distantly related bat species with diverse ecology suggests that the pathogen may be a generalist and that all bats hibernating within the distribution range of P. destructans may be at risk of infection

The Long-Baseline Neutrino Experiment: Exploring Fundamental Symmetries of the Universe

The preponderance of matter over antimatter in the early Universe, the dynamics of the supernova bursts that produced the heavy elements necessary for life and whether protons eventually decay --- these mysteries at the forefront of particle physics and astrophysics are key to understanding the early evolution of our Universe, its current state and its eventual fate. The Long-Baseline Neutrino Experiment (LBNE) represents an extensively developed plan for a world-class experiment dedicated to addressing these questions. LBNE is conceived around three central components: (1) a new, high-intensity neutrino source generated from a megawatt-class proton accelerator at Fermi National Accelerator Laboratory, (2) a near neutrino detector just downstream of the source, and (3) a massive liquid argon time-projection chamber deployed as a far detector deep underground at the Sanford Underground Research Facility. This facility, located at the site of the former Homestake Mine in Lead, South Dakota, is approximately 1,300 km from the neutrino source at Fermilab -- a distance (baseline) that delivers optimal sensitivity to neutrino charge-parity symmetry violation and mass ordering effects. This ambitious yet cost-effective design incorporates scalability and flexibility and can accommodate a variety of upgrades and contributions. With its exceptional combination of experimental configuration, technical capabilities, and potential for transformative discoveries, LBNE promises to be a vital facility for the field of particle physics worldwide, providing physicists from around the globe with opportunities to collaborate in a twenty to thirty year program of exciting science. In this document we provide a comprehensive overview of LBNE's scientific objectives, its place in the landscape of neutrino physics worldwide, the technologies it will incorporate and the capabilities it will possess.Comment: Major update of previous version. This is the reference document for LBNE science program and current status. Chapters 1, 3, and 9 provide a comprehensive overview of LBNE's scientific objectives, its place in the landscape of neutrino physics worldwide, the technologies it will incorporate and the capabilities it will possess. 288 pages, 116 figure

Differential cross section measurements for the production of a W boson in association with jets in proton–proton collisions at √s = 7 TeV

Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse momenta (pT) and pseudorapidities of the four leading jets, the scalar sum of jet transverse momenta (HT), and the difference in azimuthal angle between the directions of each jet and the muon. The data sample of pp collisions at a centre-of-mass energy of 7 TeV was collected with the CMS detector at the LHC and corresponds to an integrated luminosity of 5.0 fb[superscript −1]. The measured cross sections are compared to predictions from Monte Carlo generators, MadGraph + pythia and sherpa, and to next-to-leading-order calculations from BlackHat + sherpa. The differential cross sections are found to be in agreement with the predictions, apart from the pT distributions of the leading jets at high pT values, the distributions of the HT at high-HT and low jet multiplicity, and the distribution of the difference in azimuthal angle between the leading jet and the muon at low values.United States.

Impacts of the Tropical Pacific/Indian Oceans on the Seasonal Cycle of the West African Monsoon

The current consensus is that drought has developed in the Sahel during the second half of the twentieth century as a result of remote effects of oceanic anomalies amplified by local land–atmosphere interactions. This paper focuses on the impacts of oceanic anomalies upon West African climate and specifically aims to identify those from SST anomalies in the Pacific/Indian Oceans during spring and summer seasons, when they were significant. Idealized sensitivity experiments are performed with four atmospheric general circulation models (AGCMs). The prescribed SST patterns used in the AGCMs are based on the leading mode of covariability between SST anomalies over the Pacific/Indian Oceans and summer rainfall over West Africa. The results show that such oceanic anomalies in the Pacific/Indian Ocean lead to a northward shift of an anomalous dry belt from the Gulf of Guinea to the Sahel as the season advances. In the Sahel, the magnitude of rainfall anomalies is comparable to that obtained by other authors using SST anomalies confined to the proximity of the Atlantic Ocean. The mechanism connecting the Pacific/Indian SST anomalies with West African rainfall has a strong seasonal cycle. In spring (May and June), anomalous subsidence develops over both the Maritime Continent and the equatorial Atlantic in response to the enhanced equatorial heating. Precipitation increases over continental West Africa in association with stronger zonal convergence of moisture. In addition, precipitation decreases over the Gulf of Guinea. During the monsoon peak (July and August), the SST anomalies move westward over the equatorial Pacific and the two regions where subsidence occurred earlier in the seasons merge over West Africa. The monsoon weakens and rainfall decreases over the Sahel, especially in August.Peer reviewe

Optimasi Portofolio Resiko Menggunakan Model Markowitz MVO Dikaitkan dengan Keterbatasan Manusia dalam Memprediksi Masa Depan dalam Perspektif Al-Qur`an

Risk portfolio on modern finance has become increasingly technical, requiring the use of sophisticated mathematical tools in both research and practice. Since companies cannot insure themselves completely against risk, as human incompetence in predicting the future precisely that written in Al-Quran surah Luqman verse 34, they have to manage it to yield an optimal portfolio. The objective here is to minimize the variance among all portfolios, or alternatively, to maximize expected return among all portfolios that has at least a certain expected return. Furthermore, this study focuses on optimizing risk portfolio so called Markowitz MVO (Mean-Variance Optimization). Some theoretical frameworks for analysis are arithmetic mean, geometric mean, variance, covariance, linear programming, and quadratic programming. Moreover, finding a minimum variance portfolio produces a convex quadratic programming, that is minimizing the objective function ðð¥with constraintsð ð 𥠥 ðandð´ð¥ = ð. The outcome of this research is the solution of optimal risk portofolio in some investments that could be finished smoothly using MATLAB R2007b software together with its graphic analysis

AI is a viable alternative to high throughput screening: a 318-target study

: High throughput screening (HTS) is routinely used to identify bioactive small molecules. This requires physical compounds, which limits coverage of accessible chemical space. Computational approaches combined with vast on-demand chemical libraries can access far greater chemical space, provided that the predictive accuracy is sufficient to identify useful molecules. Through the largest and most diverse virtual HTS campaign reported to date, comprising 318 individual projects, we demonstrate that our AtomNet® convolutional neural network successfully finds novel hits across every major therapeutic area and protein class. We address historical limitations of computational screening by demonstrating success for target proteins without known binders, high-quality X-ray crystal structures, or manual cherry-picking of compounds. We show that the molecules selected by the AtomNet® model are novel drug-like scaffolds rather than minor modifications to known bioactive compounds. Our empirical results suggest that computational methods can substantially replace HTS as the first step of small-molecule drug discovery
