Keys to quality infant/toddler care: Nurturing baby\u27s life journey

Teachers of infants need a large bunch of key ideas and activities of all kinds to unlock in each child the treasures of loving kindness, thoughtful and eloquent use of language, intense active curiosity to learn, willingness to cooperate, and the deep desire to work hard to master new tasks. Here are some ideas that teachers can use during interactions with infants to optimize each child’s development

Autocracies as Mediators in Conflicts

It is puzzling why autocracies, which typically are not renowned for their human rights record or their observance of international norms related to human rights and are frequently inured in their own violent conflicts, would choose to take on the seemingly humanitarian role of peacemaker as often as democracies in the conflicts of other states in the absence of such things as a former colonial relationship or shared geographic proximity with them. I argue that autocracies will offer more often to mediate when they are subjected to international scrutiny, sanctioning, and/or condemnation, as well as materially and immaterially benefitting from their efforts afterwards. I also posit that based on institutional attributes such as the presence of a professional bureaucracy (such as is found in a party “machine” autocracy) or by contrast an all-powerful autocrat (such as is found in personalist regimes), different autocratic regime-types will be more likely to offer to mediate than others. To test my theory, I utilize Large-N datasets about international mediation and autocratic regimes, as well as qualitative sources including information derived from the United Nations, the U.S. State Department, Human Rights Watch, Amnesty International, news articles/reports, and statements and criticisms from various states, in order to investigate when autocracies offer to mediate interstate conflicts, as well as which types of autocracies are most likely to offer to mediate an end to an international conflict. Quantitative analysis yielded some inconclusive results, however finding that Party-based autocracies are most likely to offer to mediate an international conflict when being sanctioned relative to other types of autocracies, while qualitative analysis did indeed uncover evidence that when being subjected to international condemnation and scrutiny, autocracies are likely to offer to mediate international conflict

Predicted Abundances of Carbon Compounds in Volcanic Gases on Io

We use chemical equilibrium calculations to model the speciation of carbon in volcanic gases on Io. The calculations cover wide temperature (500-2000 K), pressure (10^-8 to 10^+2 bars), and composition ranges (bulk O/S atomic ratios \~0 to 3), which overlap the nominal conditions at Pele (1760 K, 0.01 bar, O/S ~ 1.5). Bulk C/S atomic ratios ranging from 10^-6 to 10^-1 in volcanic gases are used with a nominal value of 10^-3 based upon upper limits from Voyager for carbon in the Loki plume on Io. Carbon monoxide and CO2 are the two major carbon gases under all conditions studied. Carbonyl sulfide and CS2 are orders of magnitude less abundant. Consideration of different loss processes (photolysis, condensation, kinetic reactions in the plume) indicates that photolysis is probably the major loss process for all gases. Both CO and CO2 should be observable in volcanic plumes and in Io's atmosphere at abundances of several hundred parts per million by volume for a bulk C/S ratio of 10^-3.Comment: 21 pages, 4 figures, 4 tables; accepted by Astrophysical Journa

Structural dichroism in the antiferromagnetic insulating phase of V_2O_3

We performed near-edge x-ray absorption spectroscopy (XANES) at V K edge in the antiferromagnetic insulating (AFI) phase of a 2.8% Cr-doped V_2O_3 single crystal. Linear dichroism of several percent is measured in the hexagonal plane and found to be in good agreement with ab-initio calculations based on multiple scattering theory. This experiment definitively proves the structural origin of the signal and therefore solves a controversy raised by previous interpretations of the same dichroism as non-reciprocal. It also calls for a further investigation of the role of the magnetoelectric annealing procedure in cooling to the AFI phase.Comment: 4 pages 3 figures. To be published in Phys. Rev. B (2005

Introduction

IN The Curious Enlightenment of Professor Caritat—Steven Lukes' fictionalized round-up of contemporary political theory—the hapless professor has been kidnapped by the resistance movement and sent off to search for grounds for optimism. In Utilitaria, he is asked to give a lecture on “Breaking Free from the Past;” in Communitaria, on “Why the Enlightenment Project Had to Fail.” Neither topic is much to his taste, but it is only when he reaches Libertaria (not, as one of its gloomy inhabitants tells him, a good place to be unlucky, unemployed, or employed by the state) that he is made to recognize the limited purchase of his academic expertise. At the end of the book, the professor still has not found the mythical land of Egalitaria. But he has derived one important lesson from his adventures: in the pursuit of any one ideal, it is disastrous to lose sight of all the others

Dynamic phenomena in superconducting oxides by ESR

Dynamic electron spin resonance (ESR) measurements compare the paramagnetic and antiferromagnetic (AF) properties of superconducting oxides in the range 4 K to room temperature, at 8 MHz and 9.36 GHz. Two are derivatives of YBa2Cu30 7: 1: Nd(Nd0.05Ba0.95 )2Cu30 7, Te0 =72 K and II: Y0.2Cao.8Sr2[Cu2(Tlo.5Pb0.5 )]07, Te0 =108 K and two are cases where AF ordering dominates the weak superconductivity: III: Nb01.1\u3e 1. 25 ~Teo~ 10 K and IV: La2Ni04.00, 70 K :::: Teo:::: 40 K. At temperatures 298:::: T:::: 64 K, the ESR absorption by I indicates orthorhombic symmetry. The peaks at Ke =2.06, gb =2.13, and Ka =2.24 are identified with the presence of 5% Nd3+( 41912 ) in the Ba layer because the characteristic Cu2+ impurity hyperfine structure is absent and the ESR signal disappears several degrees below Te. Near Te the ESR absorption is reduced by two orders of magnitude. Proximity effects give rise to interference fringes with period r1 ( T) independent of the field B and the rate of sweep dBzldt. ESR is observed below Te because flux penetrates the superconductor. The temperature dependence of r1 leads to an activation energy for the flux motion E0 (1)/R ~ 16 K and Ea (111)/R ~3 K =Te /4. In the superconducting state a coherent flux expulsion response to a change in B. from 500 mT to zero is observed in times T, = 8 to 10 s. The inverse rate of noise spikes due to flux expulsion, when the samples are cooled through Te in a magnetic field, varies from Tnoise=3.5 s for III to 21 s for IV. The microwave absorption spectra identify three temperature regimes: (i) For 3.5 K \u3c T \u3c T m T* \u3c Teo superconducting behavior was confirmed by the energy loss near zero magnetic field and the kinetics of high-field noise due to flux expulsion. Near g =2.00 ESR absorption is observed for all materials. A broad absorption near 50 to 100 mT at 9.36 GHz has been attributed to AF resonance. (ii) T m T* ~ T ~ Te identifies the range where flux motion gives rise to interference fringes in the ESR absorption. (iii) ESR and AF resonance are observed immediately after warming above Tc

Agrin isoforms and their role in synaptogenesis

Agrin is thought to mediate the motor neuron-induced aggregation of synaptic proteins on the surface of muscle fibers at neuromuscular junctions. Recent experiments provide direct evidence in support of this hypothesis, reveal the nature of agrin immunoreactivity at sites other than neuromuscular junctions, and have resulted in findings that are consistent with the possibility that agrin plays a role in synaptogenesis throughout the nervous system
