Nature or Nurture—On the Development of Children’s Language

Referring to children’s development,especially the development of children’s language,there is a question that people are very interested in,that is,does the development of children’s language on earth depend on innate inheritance or postnatal environment? In order to answer this question,this paper begins with the definition of the development of children’s language,then,expounds some theories on language acquisition,finally,finds out the crucial factors influencing the development of children’s language.     

Improving the accuracy of GRACE Earth’s gravitational field using the combination of different inclinations

In this paper, the GRACE Earth’s gravitational field complete up to degree and order 120 is recovered based on the combination of different inclinations using the energy conservation principle. The results show that because different inclinations of satellite are sensitive to the geopotential coefficients with different degrees l and orders m, the design of GRACE exploiting 89o inclination can improve effectively the accuracy of geopotential zonal harmonic coefficients. However, it is less sensitive to the geopotential tesseral harmonic coefficients. Accordingly, the second group of GRACE exploiting lower inclination is required to determine high-accurately the geopotential tesseral harmonic coefficients and cover the shortage of the single group of GRACE exploiting 89o inclination. Two groups of GRACE individually exploiting 89o+(82o－84o) inclinations are the optimal combination of the Earth’s gravitational field recovery complete up to degree and order 120. In the degree 120, the joint accuracy of cumulative geoid height based on two groups of GRACE individually exploiting 89o and 83o inclinations is averagely 2 times higher than the accuracy of a group of GRACE exploiting 89o inclination.

t-bit semiclassical quantum Fourier transform

Because of the difficulty of building a high-dimensional quantum register,this paper presents an implementation of the high-dimensional quantum Fourier transform(QFT)based on a low-dimensional quantum register.First,we define the t-bit semi- classical quantum Fourier transform.In terms of probability amplitude,we prove that the transform can realize quantum Fourier transformation,illustrate that the requirement for the two-qubit gate reduces obviously,and further design a quantum circuit of the transform.Combining the classical fixed-window method and the implementation of Shor’s quantum factorization algorithm,we then redesign a circuit for Shor’s algorithm,whose required computation resource is approximately equal to that of Parker’s.The requirement for elementary quantum gates for Parker’s algorithm is 3 O (logN),and the quantum register for our circuit re- quires t-1 more dimensions than Parker’s.However,our circuit is t2 times as fast as Parker’s,where t is the width of the window.     

Non-Fourier heat conduction study for steady states in metallic nanofilms

As a fundamental theory of heat transfer, Fourier’s law is valid for most traditional conditions. Research interest in non-Fourier heat conditions is mainly focused on heat wave phenomena in non-steady states. Recently, the thermomass theory posited that, for steady states, non-Fourier heat conduction behavior could also be observed under ultra-high heat flux conditions at low ambient temperatures. Significantly, this is due to thermomass inertia. We report on heat conduction in metallic nanofilms from large currents at low temperatures; heat fluxes of more than 1×1010 W m 2 were used. The measured average temperature of the nanofilm is larger than that based on Fourier’s law, with temperature differences increasing as heat flux increased and ambient temperature decreased. Experimental results for different film samples at different ambient temperatures reveal that non-Fourier behavior exists in metallic nanofilms in agreement with predictions from thermomass theory.     

Modeling of the fibrin agarose plate assay and its application for thrombolytic analysis

The fibrin agarose plate assay is widely used in the detection of thrombolysis efficacy. However, a rigorous mathematical model for analyzing data or comparing activities of different thrombolytics has been absent. This study investigated the relationship between thrombolysis radius, R, and diffusion time, t, of molecular medicines in an agarose hydrogel system by deriving a model based on Fick’s law and experimental verification by the fibrin agarose plate assay method. The theoretical results showed that a plot of log(R) versus log(t) has a linear curve with the slope of 1/2 and this was verified by experimental results using urokinase as a modeling agent. Moreover, it was found that R÷t is constant for a specific thrombolytic and can be used as a parameter for evaluating activities of different thrombolytics. The theoretical model has potential for improving the understanding of mecha-nisms involved in molecular medicine diffusion and offers benefits for thrombolytic therapy.

Impact of ERP Investment on Company Performance: Evidence from Manufacturing Firms in China

Information Technology (IT) investments, especially Enterprise Resource Planning (ERP) systems, are critical for the survival and development of companies. Therefore, understanding the impact of ERP investment is of great importance to managers and researchers. As a corporate performance indicator, Tobin’s Q has some inherent advantages compared to other accounting indicators, and it can better reflect the contribution of ERP investment to company performance. This study employs multiple regression models to examine the impact of ERP investment on Tobin’s Q. The sample consists of 126 manufacturing companies listed on the Shanghai and Shenzhen Stock Exchanges from 1999 to 2007. Empirical results show that in the first three years after ERP implementation, there is no significant change in Tobin’s Q; however, in the fourth year, Tobin’s Q increases significantly. The results indicate that, as a strategic long-term investment accompanied by large-scale business process reengineering and organizational learning, ERP implementation has time-lagged effects; nonetheless, it eventually produces significant benefits.     

The equilibrium between diagenetic calcites and dolomites and its impact on reservoir quality in the sandstone reservoir of Kela 2 gas field

Based on the equilibrium theory of chemical reactions between water and rocks, this paper establishes a thermodynamic phase relationship diagram among calcites, dolomites and water solution under the condition of diagenesis based on the thermodynamic database of related minerals and fluids and dolomite’s degree of order parameters. It has been discovered that the equilibrium between calcites and dolomites in the diagenetic environment is strongly impacted by temperature and the Ca/Mg ratios in groundwater, and that the dolomite’s degree of order in the diagenetic environment is a function of crystallization temperature and time, not controlled by water solution. Hereby, the authors make a further analysis of the close relationship of chemical reaction between carbonate cements and pore water in the sandstone reservoirs of Kala 2 gas field in Kuche sag. It can be seen that there are different impacts on sandstone reservoir quality among the equilibrium system of calcites, dolomites and pore water at different depths of reservoirs.

＂The Flea＂ and ＂A Valediction：Forbidding Mourning＂

John Donne is a representative of 17th century English metaphysical poets.Donne’s poetry embraces a wide range of secular and religious subjects.His poetry is full of philosophical metaphor,and quick thinking activities are lively and strong passions-love passion and the passion of religious integration,which created a new harmony.Reading Donne’s poetry is like participating in a mental game,only use our brains in order to catch up with speeding on the poet’s imagination,his exquisite taste of the speculation.The Flea is one of representative works by John Donne.A Valediction: Forbidding Mourning is the most famous works of Donne’s works.Both "The Flea" and "A Valediction: Forbidding Mourning" are famous love poems by John Donne.The two poems have something in common and something different.Although the two poems are similar and also different to each other,they both set their own situation properly and impressively.     

On Kenneth Burke’s Dramatism

Dramatism is the essence of Kenneth Burke’s thoughts.To further understand its intrinsic qualities,this paper analyzes its three theoretical foundations from Burke’s views on humanity,language and rhetoric.Then it provides comments on dramatism.After a comprehensive exploration of these three theoretical foundations,it reveals that Burke’s dramatized world is a world of meaning or rhetoric,not a world of matter.In this dramatized world,human beings’behavior is a kind of symbolic action.     

Structure and collaboration relationship analysis in a scientific collaboration network

We construct a weighted network of scientific collaboration in computational geometry and study the statistical properties of the network. In addition, we introduce a parameter called the collaboration relationship parameter to measure the collaboration between scientists. The collaboration relationship parameter of two scientists depends not only on the connection weights between the nodes, but also on the network’s structure. The stability of the network’s structure in terms of different edge removal strategies is also studied. According to the parameter, we find that a community structure exists in this type of network.

Spatial prisoner’s dilemma games with increasing size of the interaction neighborhood on regular lattices

We studied the evolution of cooperation in the prisoner’s dilemma game on a square lattice where the size of the interaction neighborhood is considered. Firstly, the effects of noise and the cost-to-benefit ratio on the maintenance of cooperation were investigated. The results indicate that the cooperation frequency depends on the noise and cost-to-benefit ratio: cooperation reaches a climax as noise increases, but it monotonously decreases and even vanishes with the ratio increasing. Furthermore, we investigated how the size of the interaction neighborhood affects the emergence of cooperation in detail. Our study demonstrates that cooperation is remarkably enhanced by an increase in the size of the interaction neighborhood. However, cooperation died out when the size of the interaction neighborhood became too large since the system was similar to the mean-field system. On this basis, a cluster-forming mechanism acting among cooperators was also explored, and it showed that the moderate range of the neighborhood size is beneficial for forming larger cooperative clusters. Finally, large-scale Monte Carlo simulations were carried out to visualize and interpret these phenomena explicitly.

The Queen’s Torture and The Winter’s Tale

The further exploration is carried out to have a deeper understanding of King Leontes and his jealousy and violence. Autolycus, the rogue, is given a detailed avaluation so as to reveal his active role in the play and the artistic flavour on the stage. The brave and straight forward lady Paulina is held in high regard because of both of her brilliant words and benevolent actions. The fourth Act of the play is regarded as the excellent part of the play based on its rich and colourful picture of the rural life by the playwright Shakespeare. Since Hermione, the heroine, is the main character of all the main characters, and the fate of hers is the focus of the whole play, so the title of this play is in need of change.
