Process model of IT impacts on firm competitiveness based on application capability of information technology

To investigate the process of information technology （IT） impacts on firm competitiveness, an integrated process model of IT impacts on firm competitiveness is brought forward based on the process-oriented view, the resource-based view and the complementary resource view, which is comprised of an IT conversion process, an information system （IS） adoption process, an IS use process and a competition process. The application capability of IT plays the critical role, which determines the efficiency and effectiveness of the aforementioned four processes. The process model of IT impacts on firm competitiveness can also be used to explain why, under what situations and how IT can generate positive organizational outcomes, as well as theoretical bases for further empirical study.

Illustrations for Dante＇s Inferno： A Comparative Study of Sandro Botticelli, Giovanni Stradano, and Federico Zuccaro

This essay is twofold： the first part focuses on the interpretation of the concept of Hell in Dante＇s Inferno and Italian culture as depicted in Last Judgment scenes such as Giotto＇s in the Arena Chapel of Padua; Signorelli＇s in the Orvieto Cathedral; and Michelangelo＇s in the Sistine Chapel in Rome. The second part deals with the drawing illustrations for the text of Dante＇s Divine Comedy composed by the Florentine painters Sandro Botticelli, Giovanni Stradano, and Federico Zuccaro. Here the emphasis is on Dante＇s Inferno, which comments upon Neoplatonic personalities, Florentine politics, and current popular art. Comparisons with some of Botticelli＇s, Stradano＇s, and Zuccaro＇s drawing illustrations indicate the assimilation of classical artistic concepts such as Horace＇s ut pictura poesis [as is painting so is poetry] as well as Plato＇sfurorpoeticus [poetical inspiration] promoted in the writings of Marsilio Ficino, a Renaissance Neoplatonic philosopher.

Microstructure,mechanical properties and corrosion performance of selective laser melting Ti/GNPs composite with a porous structure

In this study,nano-graphene reinforced titanium matrix composites(GNPs/Ti)with a honeycomb porous structure were fabricated by selective laser melting(SLM).The effects of graphene on the microstructure,mechanical properties and corrosion performance of the SLM GNPs/Ti were systematically investigated.Results of microstructure characterization show that:1)the density of the SLM GNPs/Ti was improved as compared to that of the SLM Ti;2)abundant TiC particles were formed in the SLM GNPs/Ti.The hardness and compressive strength of the composite increased by 90%(from HV 236 to HV 503)and 14%(from 277 MPa to 316 MPa),respectively,attributed to the uniformly distributed TiC and fine GNPs in the Ti matrix.Electrochemical tests reveal that the corrosion current density of the SLM GNPs/Ti is only 0.328μA/cm^(2),that is about 25%less than that of the SLM Ti.The results indicate that the incorporation of nano-graphene is a potential method to strengthen the Ti by SLM.

Transition of super-hydrophobic states of droplet on rough surface

Twelve samples with periodic array square pillars microstructure were prepared on the silicon wafer by plasma etching techniques, on which space b of the square pillars increased from 5 to 60 μm. In order to study the effect ofb on the wettability of the rough surface, the effects of apparent contact angle （CA） and sliding angle （a） of the droplet on the rough surface were measured with the contact angle meter. The results show that the experimental values of CA well agree with the classical wetting theory and a decreases with the increase of b. Two drop shapes exist on the samples＇ surface, corresponding to the Cassie state and the Wenzel state respectively. The contact state in which a drop would settle depends typically on the size of b. On the role of gravitation, the irreversible transition of a drop from Cassie state to Wenzel state should occur at a certain space of the square pillars. Since the transition has implications on the application of super-hydrophobic rough surfaces, theoretically, the prediction of wetting state transition on square pillar array micro-structured surfaces provides an intuitionistic guidance for the design of steady superhydrophobic surfaces.

Macro and meso analysis of jointed rock mass triaxial compression test by using equivalent rock mass(ERM) technique

Methods that can efficiently model the effects of rock joints on rock mass behavior can be beneficial in rock engineering. The suitability of equivalent rock mass(ERM) technique based upon particle methods is investigated. The ERM methodology is first validated by comparing calculated and experimental data of lab triaxial compression test on a set of cylindrical rock mass samples, each containing a single joint oriented in various dip angles. The simulated results are then used to study the stress-strain nonlinearity and failure mechanism as a function of the joint dip angle and confining stress. The anisotropy and size effects are also investigated by using multi-scale cubic ERM models subjected to triaxial compression test. The deformation and failure behavior are found to be influenced by joint degradation, the micro-crack formation in the intact rock, the interaction between two joints, and the interactions of micro-cracks and joints.

孟子的观人术与气论

在观人的方法与旨趣上,孟子与孔子有着颇大的差异。这种现象,来源于孔、孟之际儒家道德学说的拓展演变:一方面,对于道德的探讨愈发内化、精密;另一方面,气论哲学被纳入儒家思孟一系的学说中,形成'以气论德'的思路,直接影响了孟子观人时的思路和判断。本文进而指出,就学术渊源而论,孟子的气论与黄老道家的抟气术有着密切的关联,然而出于一名儒者的立场,孟子又对其进行了改造。二者间的同异,折射出战国时期各家思想交融碰撞的宏大思想史画面。

Intergranular Corrosion of UNS S31803 Heat Treated at 800 ℃ Varying Range Times

The aim of this work is evaluate the intergranular corrosion on UNS S31803 steel, with heat treatments at 800 ℃, varying treatment times of 30 mins, 360 mins and 1,440 mins. The results confirm the formation of o phases and secondary austenite （γ2）. For the analysis of the influence of o and γ2 phases, metallographic analysis were conducted through optical microscopy, potentiokinetic reactivation electrochemical techniques and potentiodynamic polarization in NaCI 3.5% solution. Microstructural analysis has shown a formation of γ2 and o phase in heat treatment, due to diffusion of chromium and molybdenum from δ phase to y phase, precipitating on δ/γ and δ/δ interfaces. The DL-EPR （Double loop electrochemical potentiokinetic reactivation） results have shown an increase of the DOS （degree of sensitization） for long periods of time on heat treatment. The results of potentiodynamic polarization showed a reduction of the corrosion and pitting potentials, followed by an increase of the current density when the UNS S31830 steel is heat treated during long periods of time.

Observation of the in vitro Transcription of the Mouse (Balb/c) Heart Nuclear DNA Fragments by AFM

It is observed that the regulation sequences at the two ends of every active gene of the heart nuclear DNA fragments may differentially combine with active regulation factors such as some specific binding proteins by using AFM and other experimental technologies. These active genes form different "gene knots", which are separated by "intervals". Using AFM, occasionally, it is also discovered that during the transcription stage, the heart nuclear DNA fragments consist of 3 4 5 "gene knots" and related "intervals", which form various "gene lineages" respectively by some "permutation and combination". Each gene lineage is likely to form nRNA chain like complexes that are 3 times the quantity of gene knots, and each nRNA chain like complex is connected with both ends of corresponding gene lineage. One gene knot of the DNA fragments participates the formation of different gene lineage and corresponding RNA chain like complexes by different combination. By posttranscriptional modification, they can form nmRNA linear chain like complexes that show the speciality of tissues. The beginnings of transcription units have the same number as gene lineages, and all gene lineages in DNA molecules may transcribe efficiently from corresponding beginnings of transcription unit simultaneously. Our work shows the prospective application of AFM in the research of the diversity of gene lineages formation from gene knots in the transcription stage and the efficiency of gene knots transcription.
