To verify the newly developed decision assisting expert system for nitrogen fertilizer application NES to Illinois cornfields, a couple of N rate studies from Dr. Howard and five Illinois Agricultural Experiment Stations were applied. Four types of recommendations including the current Illinois recommendation, Hoeft recommendation, NES, and maximum economic recommendation were compared with each other for the crop yields, profits, recovery rate, and N losses to cornfields. The N rate of NES recommendation, considering productivity index (PI), soil organic matter content (SOM), and pre-sidedressing nitrate concentration (PSNT) level, was the lowest in comparison to those of other recommendations. However, N recovery rate in NES was generally higher and the resulting N loss was lower than others. But, adherence to the recommendations may also reduce farmers income if environmental expense did not considered. Therefore, NES will be more effective by adding the factors including environmental expense, tillage systems, crop rotation, and other agricultural management parameters.

Due to the expandability of smartphone, the mobile application market is growing explosively. However, as happens in other digital contents markets, piracy of mobile applications is prevalent. This study investigated the effects of behavioral factors on smartphone application piracy. The research model consists of factors from the theory of planned behavior model - subjective norms, attitudes toward piracy and perceptions of behavioral control. In addition, perceived consequences, past behavior and habit was included. The past behavior of PC software piracy was a meaningful predictor of habit, and habit was found to influence significantly the smartphone piracy intention. The result also shows that perceived benefit had significant effect on attitude, but both perceived legal and technical risk were not significantly related to attitude. Implications for research and practice are discussed.

With the business environment rapidly changing, organizational politics becomes a general and inevitable phenomenon in organizations. Employees' perception of organizational politics (POP) both has positive functions and negative functions, but many study results found it has a negative effects on employees' attitudes and behaviors. Despite the awareness of the importance in managing the negative effects of organizational politics at the workplace is increasing, research relating to employees' POP hasn't received much attention in China. With empirical analysis, the main findings come as follow: Firstly, POP has a significant positive(+) effect on turnover intention and a significant negative(-) effect on OCB. Secondly, Through the mediation of job stress, POP is indirectly and positively(+) associated with turnover intention and negatively(-) associated with OCB. Lastly, Procedural justice has a moderating effects between POP and job stress.

As the injunctive effect on the real estate gets announced in public once the seizure register gets exercised in terms of auction and the action of disposal by the real estate owner afterwards becomes nullified in the relationship with a seizure creditor or a successful bidder, the register performed by the cause of disposal action that cannot confront with the seizure or provisional seizure, becomes cancelled in virtue of a registration officer's office. Accordingly, in case of being a singular successor who relatively loses property in a relationship toward the successful bidder due to the injunctive effect of provisional seizure, the identity with building owner and land owner as the precondition of establishing legal superficies according to the custom must be decided based on the time of provisional seizure. The Supreme Court Decision 2010Da52140 delivered on October 18, 2012 has great significance from the fact that it has settled inconsistency in existing precedent cases with such purpose.

This study has investigated how attachment anxiety boosts the attitude on charity appeals. Drawing on the attachment theory, we tested the hypothesis that increasing attachment anxiety (both dispositionally and temporarily primed) would have favorable attitudes towards charity appeals relates to social identification. Participants in high attachment anxiety showed more favorable attitudes towards charity appeals which can fulfill their social needs. Needs for belongness mediated the relationship between charity appeals and attachment anxiety. While past research has focused on the attachment security as motivation for helping, The current study has focused on egoistic motivation for helping and examined that attachment insecurities leads more favorable attitudes towards charity appeals that fulfill their social needs. The current study demonstrates that social needs can motivate consumers' prosocial behavior. Implications for the theory of non-profit marketing are discussed.

Preparation and properties of potential CVD (Chemical Vapor Deposition) precursors for the TiO2, a major component of the perovskite materials such as PT, PLT, PZT, and PLZT were investigated. Reactions between β-diketones and TiMe3, formed in situ failed to produce stable Ti(β-diketonate)3 complexes but a stable purple solid, characterized as (OTi(BPP)2)2 (BPP=1,3-biphenyl-1,3-propanedione) was obtained when BPP was used. Several new Ti(Oi-Pr)2(β-diketonate)2 complexes with aromatic or ring substituents were synthesized by the substitution reaction of Ti(OiPr)4by β-diketones and characterized with 1H NMR, IR, ICP, and TGA. Solid complexes such as Ti(Oi-Pr)2(BAC)2 (BAC=1.-phenyl-2,4-pentanedione), Ti(Oi-Pr)2(BPP)2, Ti(Oi-Pr)2(1-HAN)2 (1-HAN=2-hydroxy-1-acetonaphthone), Ti(Oi-Pr)2(2-HAN)2 (2-HAN=1-hydroxy-2-acetonaphthone), Ti(Oi-Pr)2(ACCP)2 (ACCP=2-acetylcyclopentanone), and Ti(Oi-Pr)2(HBP)2 (HBP=2-hydroxybenzophenone) were found to be stable toward moisture and air. Ti(Oi-Pr)2(ACCP)2 and Ti(Oi-Pr)2(HBP)2 were proved to have lower melting points and higher decomposition temperatures. However, these complexes are thermally stable and pyrolysis under an inert atmosphere resulted in incomplete decomposition. Ti(Oi-Pr)2(DPM)2 (DPM=dipivaloylmethane) and Ti(Oi-Pr)2(HFAA)2 (HFAA=hexafluoroacetylacetone) were sublimed substantially during the thermal decomposition. Pyrolysis mechanism of these complexes are dependent on type of β-diketone but removal of Oi-Pr ligands occurs before the decomposition of β-diketonate ligands.
