Rosenberg Method Research Articles

Interakcje społeczno-pedagogiczne z odbiorcami usług informacyjnych bibliotek naukowych w punkcie informacji katalogowej

The article presents socio-pedagogical interactions with library users at the library helpdesk of a scientific library. The tasks of a reference librarian, assisting users in their catalogue search, formally fall within the scope of information science departments. The library helpdesk in often where users make the first contact with the library. The essence of good social contact is mutual respect and the subjective approach to the recipient of library services. The appropriate attitude of the librarian, kindness marked by non-violent communication (according to the M.B. Rosenberg method), expressing interest in the user's needs and commitment needed to provide assistance require a language appropriate to the age of the interlocutor and skillful balancing between the psychological spheres: “Me-Adult”, “Me-Parent”, “Me-Child” of interlocutors (presented in the transactional analysis by E. Berne). Modern technological progress, in terms of tools and information resources, demand constant development of professional skills: both hard and soft skills of a reference librarian, so that she/he can adequately respond to the needs of an recipients of reference services: both teenagers and adults, but often with low information literacy, as well as persons experiencing difficulties in adaptating to the fast changes of postmodernity.

Strong effects of ionizing radiation from Chernobyl on mutation rates.

In this paper we use a meta-analysis to examine the relationship between radiation and mutation rates in Chernobyl across 45 published studies, covering 30 species. Overall effect size of radiation on mutation rates estimated as Pearson's product-moment correlation coefficient was very large (E = 0.67; 95% confidence intervals (CI) 0.59 to 0.73), accounting for 44.3% of the total variance in an unstructured random-effects model. Fail-safe calculations reflecting the number of unpublished null results needed to eliminate this average effect size showed the extreme robustness of this finding (Rosenberg's method: 4135 at p = 0.05). Indirect tests did not provide any evidence of publication bias. The effect of radiation on mutations varied among taxa, with plants showing a larger effect than animals. Humans were shown to have intermediate sensitivity of mutations to radiation compared to other species. Effect size did not decrease over time, providing no evidence for an improvement in environmental conditions. The surprisingly high mean effect size suggests a strong impact of radioactive contamination on individual fitness in current and future generations, with potentially significant population-level consequences, even beyond the area contaminated with radioactive material.

Needs and Nonviolent Communication in the Religious Studies Classroom

AbstractReligious studies classrooms are microcosms of the public square in bringing together individuals of diverse identities and ideological commitments. As such, these classrooms create the necessity and opportunity to foster effective modes of conversation. In this essay, I argue that communication attuned to shared human needs – among them needs for safety, respect, and belonging – offers a transformative response to the potential self‐silencing and peer‐conflict to which religious studies classrooms are prone. I develop this claim with reference to the research on teaching religious studies conducted by Barbara Walvoord and the pedagogy of theologian and Swarthmore University President Rebecca Chopp in formulating an “ethics of conversation” with her students. Building on this foundation, I make a case for developing an “ethos of conversation” in the religious studies classroom based on psychologist and peace activist Marshall Rosenberg's method of “nonviolent communication.” While addressing the roles of conflict and toleration in the classroom through the perspectives of Alasdair MacIntyre and Jeffrey Stout, I argue that Rosenberg's approach to communication is a powerful asset to education that models constructive engagement in the macrocosm of civic life.

Synthesis, Characterization and Reactivity Ratio Study of Poly(di(tri-n-butyltin) citraconate-co-N-vinylimidazole)

The organotin monomer di(tri-n-butyltin) citraconate (DTBTC, I) was synthesized. Subsequently this monomer was copolymerized with N-vinylimidazole (VI) using a free radical technique. The overall conversion was kept low (≤14% wt/wt) for all studied samples and the copolymer composition was determined from tin analysis using the Gilman and Rosenberg method. The synthesized monomer and copolymer were further characterized by elemental analysis, 1H- and 13C-NMR, and FTIR spectroscopy.

Synthesis and Characterization of Organotin Containing Copolymers: Reactivity Ratio Studies

Organotin monomers containing dibutyltin groups – dibutyltin citraconate (DBTC) as a new monomer and dibutyltin maleate (DBTM) – were synthesized. Free radical copolymerizations of the organotin monomers with styrene (ST) and butyl acrylate (BA) were performed. The overall conversion was kept low (≤15% wt/wt) for all studied samples and the copolymers composition was determined from tin analysis using the Gillman and Rosenberg method. The reactivity ratios were calculated from the copolymer composition using the Fineman-Ross (FR) method. The synthesized monomers were characterized by elemental analysis, 1H-, 13C-NMR and FTIR spectroscopy.

A New Plain Radiography Method Using the Optimal Angle of Knee Flexion for Assessing Early Degeneration of the Knee Joint

During total knee arthroplasty for primary osteoarthritis, we measured the area of worn cartilage on the medial femoral condyle in 44 knees. By reference to a lateral femoral radiograph of each knee, the optimal knee flexion angle—reflecting the worn area of the femoral condyle—was determined and found to be 19.8° ± 7.6°. Using this result, a new method for posteroanterior radiography of the weight-bearing knee (20/10 radiography) was devised. We compared the use of our method with Rosenberg's method in 56 varus knees and found that the width of the cartilage space determined by our method was narrower than that determined by Rosenberg's method ( t test, <0.001). These results confirmed that 20/10 radiography well reflects the region of worn cartilage in knees with early-stage primary osteoarthritis.

Anteroposterior weight-bearing radiography of the knee with both knees in semiflexion, using new equipment

In order to obtain high reproducibility and sensitivity in the evaluation of joint space in osteoarthritic knees, we used new equipment, and established an anteroposterior weight-bearing radiograph with both knees in semiflexion taking into account our investigation of the posterior slope angle. We compared our method with the Rosenberg method, and the coefficient of variation of our method showed higher reproducibility than that of the Rosenberg method. The most essential issue is whether the bilateral leg loading radiograph can show the same sensitivity as the homolateral leg loading radiograph. We compared standing radiographs of the knee in 26° flexion with those of 26° flexion in both knees. We assessed the widths of the narrowest points of the joint spaces in the medial and lateral compartments, the condylar plateau angle, and the femorotibial angle, in 47 knees in 24 patients. The data were analyzed statistically by single regression and each correlation was of statistical significance. Our method has better reproducibility and is more comfortable for the subject than conventional methods.

Usefulness of Rosenberg's Method in the Osteoarthrosis (OA) of the Knee

Usefulness of Rosenberg's Method in the Osteoarthrosis (OA) of the Knee

撮影肢位の相違が立位膝正面Ｘ線像の計測値に与える影響の検討

Standing radiographs are useful for evaluating joint space in knees with osteoarthritis (OA). However, ordinary methods such as hemi-foot standing ar the so-called Rosenberg method have several problems. We therefore developed a new method, in which an anteroposterior radiograph is taken with both knees at about twenty-six-degree flexion.In this study, the joint space angle (JSA) and femorotibial angle (FTA) which were measured by means of the new method were compared with those by ordinary methods. Values of JSA and FTA were more or less the same between the hemi-foot and bilateral feet. Bilateral feet achieved stable lower extremities position compared with the hemi-feet. Radiographs with the knee flexion were more sensitive for evaluating JSA than those in full extension. We concluded that this method is reliable and sensitive in assessing the degree of OA.

On the one‐phase state of aqueous protein‐uncharged polymer systems: Casein‐guar gum system

Although the majority of biopolymers are incompatible in water, systems containing casein molecules and a neutral polysaccharide (guar gum galactomannan) showed phase separation only at an ionic strength above 0.09–0.2. Static light scattering, circular dichroism spectroscopy, velocity sedimentation, viscosimetry, phase analysis in different solvents, and Rosenberg's method were used to estimate the effect of polymer–solvent and polymer–polymer interactions on the phase state of casein-guar aqueous systems. Different solvent conditions were used to try to clarify the nature (electrostatic or nonelectrostatic) of the interaction between the two macromolecular species. Data obtained show that the dominant mechanism controlling the single-phase state at low ionic strength (below 0.01) involves the formation of water-soluble weak interpolymer complexes, which may be destroyed by increasing ionic strength. © 1999 John Wiley & Sons, Inc.

A solution of the convection‐conduction heat‐transfer equation in porous media by the von Rosenberg finite‐difference scheme

Abstractvon Rosenberg developed an explicit finite‐difference scheme for solution of the linear convection‐conduction partial differential equation in one space dimension. The method is stable and accurate when a dimensionless ratio of dispersion to convection is between zero and one. In this work, the von Rosenberg method was applied to a linear, one space dimensional set of coupled convection‐conduction equations. The system examined involves the change in temperature resulting from a fluid flowing through a stationary porous solid with heat transfer between the fluid and solid phases. The equations, which describe heat transfer in each phase, were solved simultaneously and, thus, the solution method was required to be implicit rather than explicit. It was observed that when the interphase convective heat‐transfer rate was small relative to the fluid velocity, an implicit solution of the von Rosenberg weighted equations provided a good solution, but when the interphase convective heat‐transfer rate was relatively large, a modified weighting on the equations provided a more accurate, stable solution. © 1994 John Wiley &amp; Sons, Inc.

On Oxygen Diffusion in tetragonal zirconia

AbstractOxygen diffusion in dense scales of tetragonal zirconia at 1100–1300°C has been studied by the so‐called interruption kinetic method (or the Rosenberg method). Assuming that oxygen vacancies are the predominant defects in zirconia (ZrO2), studies by this method provide values of the oxygen self diffusion coefficient in this oxide at its lower limit of stability, D, and the value in tetragonal zirconia can be expressed as D =2.2 · 10−3 exp (−140(kJ/mole)/RT). The studies furthermore show that the maximum non‐stoichiometry in tetragonal zirconia, X in ZrO2−x, is small and has a value about x* ∼ 0.03 at 1000–1300°C.

An extension of the one‐dimensional von Rosenberg finite difference scheme to multidimensional problems of the convection dispersion equation

AbstractThe Crank Nicolson implicit form of the finite difference analogue of the convection‐dispersion equation does not yield stable solutions when the dispersion coefficient of the medium D is too small compared with the injected fluid velocity V—i.e, 0 &lt; (R = 2D/V ΔX) &lt; 1. Von Rosenberg developed a simple, highly accurate and stable finite difference scheme for the one‐dimensional case of constant velocity and dispersion coefficient for 0 &lt; R &lt; 1. El‐Ageli extended von Rosenberg's method to the multilayered case of varying velocity and dispersion coefficient. This paper goes a step further and extends von Rosenberg's scheme to the linear multidimensional system with constant velocities and dispersion coeffcients when: 0 &lt; (Rx, Ry,…,) &lt; 1. When this new scheme is compared with the conventional Crank‐Nicolson method, it is found that even though there are some restrictions to the spacial grid spacings in relation to the time step, the computational effort is much less and the results obtained are stable.

The influence of an intermediate annealing treatment on the oxidation of copper and nickel

A study has been made of the effects of an intermediate, isothermal annealing treatment in argon on the oxidation kinetics of copper and nickel in 1 atm oxygen at 800 and 1100°C, respectively, using a semiautomatic microbalance. Changes in scale morphology and composition have been investigated using various physical techniques. The outer CuO layer formed on copper during oxidation dissociates very rapidly on annealing to give CU2O and oxygen since the partial pressure of oxygen in the gas is below the dissociation pressure of CuO but above that of Cu2O at 800°C. The CuO layer is quickly re-formed on reoxidation in oxygen. There are relatively few other changes in the oxide morphologies of either metal during annealing, although the small grains present in the scale adjacent to the metal after oxidation are able to grow. During reoxidation both metals show a reduction in oxidation rate constant because of the decrease in total cation vacancy concentration in the scale and the reduced cation vacancy gradient across the scale brought about by the reduction in oxygen partial pressure at the oxide-gas interface during annealing. The reoxidation rate constants following annealing approach those recorded prior to annealing as the equilibrium cation vacancy levels in the scales are reestablished in the oxidizing environment. Rosenberg's method for analysis of the kinetics of reoxidation has enabled the equilibrium concentrations and diffusion coefficients of cation vacancies in CU2O and NiO during oxidation in 1 atm oxygen at the appropriate temperatures to be estimated approximately. These show reasonable agreement with literature values.
