TL;DR: In this article, a Monte-Carlo method is presented for the calculation of the ground-state wavefunction and energy value of the many-body Schrodinger equation, and several refinements to the iterative scheme, including the use of variational wavefunctions to improve the energy estimate and a variance reducing technique, are also discussed.

TL;DR: This article found that the expected success was attributed more to ability and less to good luck than was the unexpected success, while the expected failure was more to lack of ability, effort, and bad luck.
Abstract: Summary
Subjects worked at a 10-item Anagrams Test. In a manipulative control condition the prior performance of subjects on a set of practice anagrams was controlled so that half of these subjects began the test with high expectations of success and half with low expectations of success As a check on the manipulation, subjects provided ratings of how confident they were that they could pass the test (i e, solve five anagrams or more) In a selective control condition subjects were not given practice items but were subsequently assigned to high versus low expectation groups on the basis of their confidence ratings The difficulty level of the items in the Anagrams Test was manipulated so that half the subjects in each condition passed the test and half failed. Subsequently all subjects were required to rate the degree to which they considered ability (or lack of ability), effort (or lack of effort), task difficulty (easy or hard), and luck (good or bad) were causes of their performance outcome (success or failure). It was found that the expected success was attributed more to ability and less to good luck than was the unexpected success The expected failure was attributed more to lack of ability and less to bad luck than was the unexpected failure There was a greater tendency for subjects to appeal to task difficulty and effort as causes of their performance when they succeeded than when they failed. These results were discussed in terms of a structural balance model of attribution behavior and also in relation to Heider's naive analysis of the causes of action

TL;DR: In this paper, it was shown that under favorable conditions these crystal planes can be identified, and their extent estimated, from photoelectric emission measurements on heterogeneous nickel surfaces, and that these surfaces are usually not sufficiently homogeneous to permit the work function of the preferred orientation to be determined accurately.

TL;DR: The effect of culture training upon productivity was accentuated in teams in which the majority of members had worked in Central America before, and had greatest effect for teams working in villages in which teams experienced relatively little difficulty in their relations with the community.
Abstract: : The study compared the performance of volunteer medical teams who received a programmed culture assimilator test with teams who did not receive the assimilator. All team members, all citizens of the United States, worked for three-week periods in Honduras and Guatemala and were rated on their success in conducting clinics and managing community development projects. The effect of culture training upon productivity was accentuated in teams in which the majority of members had worked in Central America before. Assimilator training also had greatest effect for teams working in villages in which teams experienced relatively little difficulty in their relations with the community. (Author)

TL;DR: In this article, the authors investigated the effect of particle size on catalytic selectivity in UHV ultra-thin films and showed that very small crystals of the ultra thin films present an increased proportion of low-coordinated corner atoms, and these corner atoms favor the formation of adsorbed carbocyclic reaction intermediates.

TL;DR: The way the polymerases and nuclei change properties as the ionic composition of the buffers is changed suggests that ionic effects may be a significant factor in the control of DNA synthesis in vivo.
Abstract: The DNA polymerases of the following eukaryotic tissues were studied: regenerating rat liver, normal rat liver, rat thymus, normal mouse liver and Ehrlich ascites-tumour cells. In all cases two main polymerase forms are observed, one of mol.wt. 200000, preferring denatured DNA to native calf thymus DNA primer, designated type I, and the other, designated type II, of mol.wt. 100000, showing a variable and slight preference for native calf thymus DNA primer. Some catalytic properties of these polymerases are described. Nuclei have been isolated from some of these tissues by using two different buffer systems. The ionic composition of the isolation medium is found to affect greatly the amounts and types of polymerase that bind to the nuclei, and also affects the kinetic properties of the polymerases. The way the polymerases and nuclei change properties as the ionic composition of the buffers is changed suggests that ionic effects may be a significant factor in the control of DNA synthesis in vivo. These ionic effects also explain much of the previous confusion over the localization of specific DNA polymerases.

TL;DR: In this paper, it was shown that for continuous pdf's, if the pdf is independent of the set {Xji j ≠ i} for every i = 1, 2, ···, k, k has a Dirichlet distribution, namely αi positive, xi ≥ 0, Σk i = 0, k ≥ 1.
Abstract: Let X1, X2, ···, Xk be positive random variables such that Σi = 1 k Xi < 1. It is shown, under the assumption of continuous pdf's, that if is independent of the set {Xji j ≠ i} for every i= 1, 2, ···, k then X1, X2, ···, Xk have a Dirichlet distribution, namely αi positive, xi ≥ 0, Σk i = 1 xi < 1.

TL;DR: No large differences have been found between the priming potentialities or the intrinsic DNA polymerase activities of nuclei from resting or regenerating liver and the relationship of this DNA synthesis in vitro to DNA replication or repair in vivo is briefly discussed.
Abstract: The properties of a nuclear preparation from rat liver and thymus are described. (1) Nearest-neighbour analysis after incorporation of 32P-labelled nucleotide residues from dATP, dCTP, dGTP, dTTP and arabinofuranosyl analogues of CTP and ATP shows template-dependent DNA synthesis. (2) Where primer termini are limiting, incorporation of arabinofuranosyl analogues of AMP and CMP residues proceeds to a limit indicating that both of these analogues are DNA chain terminators. (3) No large differences have been found between the priming potentialities or the intrinsic DNA polymerase activities of nuclei from resting or regenerating liver and the relationship of this DNA synthesis in vitro to DNA replication or repair in vivo is briefly discussed.

TL;DR: In this paper, a cylindrical chamber containing argon and oxygen mixtures was used to sample the oxide layer formed on aluminium by exposure to air or oxygen, and measurements were made of the deposition rate and optical absorption and emission.
TL;DR: In this article, the teaching of adaptation has been studied in the context of Biological Education. But, their focus was on the adaptation of the curriculum, and not the adaptation itself.

TL;DR: In this paper, the effect of using an image barrier instead of a step barrier is studied by reference to the computed LEED intensities for the (001) surface of copper, and the surface state resonances in the LEED intensity versus energy curves are found to be sensitive to the position and shape of the surface potential barrier.
TL;DR: The authors found that students' own value systems would more closely resemble the perceived value system of the School they selected than the perceived values systems of the Schools they rejected, and the predicted differences in correlation were very small in regard to Social Sciences and Sciences and more clearcut for Humanities.
Abstract: First-year undergraduate students enrolling in Humanities, Social Sciences, and Sciences at Flinders University completed the Rokeach Value Survey. One group ranked terminal and instrumental values in their order of importance to themselves (Own Values). The other group ranked them in the order they thought a student completing work in their School would emphasize them (School Values). It was predicted that students' own value systems would more closely resemble the perceived value system of the School they selected than the perceived value systems of the Schools they rejected. This hypothesis was generally supported by the results but the predicted differences in correlation were very small in regard to Social Sciences and Sciences and more clearcut for Humanities. Implications of the “value match” for selection and for subsequent adjustment in the work situation were discussed.
TL;DR: The results suggest that the light-dependent component of Cl− influx in G. monile is associated with the rate of non-cyclic photophosphorylation, and the dark component of the Cl − influx, which may be part of a Cl− exchange-diffusion system and not active transport, may be associated with mitochondrial respiration.
TL;DR: In this article, the effects of relativistic corrections in low-energy electron diffraction intensity calculations are assessed by reference to relativism and non-relativistic computations for tungsten (001).
TL;DR: It was concluded that if accommodation changes are occurring with large pupils, the resulting image blurring plays no part in control of rivalry, and a central component of BR control rather than one based on accommodation is suggested.
Abstract: The role of accommodation in the control of binocular rivalry (BR) has been granted various degrees of importance by Es in the past. The most recent investigation by Fry (1936) concluded that accommodation provides the basis of BR control through the blurring of retinal images. However, the present study found that the introduction of very small artificial pupils (0.5 mm) did not reduce BR control. It was concluded that if accommodation changes are occurring with large pupils, the resulting image blurring plays no part in control of rivalry. Experiment 2 tested the effect of paralyzed intrinsic eye muscles and found almost the same degree of control as in the normal state. The slight decrease of control that was present was attributed to a general performance decrement, since slight performance decrements with eye paralysis were also found in a visual reaction-time task and hand dynamometer test. In Experiment 3, it was found that the increased control that was obtained over several practice sessions was mostly retained during subsequent eye paralysis. These findings and, in addition, a very significant control of rivaling afterimage stimuli under eye paralysis strongly suggest a central component of BR control rather than one based on accommodation.
TL;DR: The deposition and layer growth of titanium, evaporated on to tungsten and rhenium field emitter tips has been studied, and field emission average work-functions measured at varying titanium layer thicknesses from less than a monolayer to several monolayers as discussed by the authors.
TL;DR: There is no evidence for the phenomenon of “quantization” of this flux ratio of Chara corallina, and the distribution of the values of this ratio shows no tendency to cluster about preferred values in integer ratios with each other.
TL;DR: In this paper, the adsorption and reaction between chlorine and titanium was studied using a layer of β-titanium epitaxed on a tungsten emitter tip.
TL;DR: In this article, an ester of indole-3-acetic acid and myo-inositol was crystallized from an extract of Zea mays extract.
TL;DR: In this paper, the energy dependence of the single-particle shell model with non-local potentials was investigated and the wave functions corresponding to singleparticle bound states were not uniquely determined by demanding merely that they reproduce the experimentally observed binding energies.
TL;DR: In this paper, the authors examined Australia-wide data and found that there did not appear to be much of a trend in the frequency of strikes and that the coal industry had lost its former domination of aggregate Australian strike activity, and a quite different industrial mix was responsible for strikes at the end of our period (1968) than at the onset of their period (1952).
Abstract: ment rates). These variables were chosen because they seemed to provide the best vehicles for capturing the broad cyclical influences on strike activity, and not because we believed that U and 6 U were necessarily of paramount importance in themselves. When Australia-wide data were examined there did not appear to be much of a trend in the frequency of strikes. This result was, however, more apparent than real, for it resulted from an approximate counterbalancing of a strong downward strike trend in the coal industry by a steady expansion of strike activity elsewhere in the growing Australian economy. As a result of these trends, the coal industry had lost its former domination of aggregate Australian strike activity, and a quite different industrial mix was responsible for strikes at the end of our period (1968) than at the onset of our period (1952). Because of this change we paid little attention to Australia-wide experience. Instead we concentrated on separate estimates for the coal industry and for the non-coal sector of
TL;DR: In this paper, the angular correlations for the reaction 40 Ca(p, 2p) 39 K have been measured at symmetric, coplanar angles between 30° and 105° for both the ground state and first excited state of 39 K.
TL;DR: In this article, the quasi-free peak for the reaction d(p, 2p)n is examined in the off-shell spectator approximation at incident energies from 14.4 MeV to 100 MeV using the Hamada-Johnstpn potential.
TL;DR: In this paper, the effect of multiple marking on the intercorrelation of marks awarded to a biology essay question in a public examination was investigated by having six markers each mark 44 scripts as part of the marking procedure in the 1969 Matriculation Biology examination set by the Public Examinations Board of South Australia.
Abstract: Summary. The effect of multiple marking on the intercorrelation of marks awarded to a biology essay question in a public examination was investigated by having six markers each mark 44 scripts as part of the marking procedure in the 1969 Matriculation Biology examination set by the Public Examinations Board of South Australia. Intercorrelation coefficients were computed for final marks based on one, two, three or four opinions. The greatest increase in mean intercorrelation coefficient resulted from an increase from one to two opinions; the additional increases when three or four markers were used were statistically significant, but of smaller magnitude.
