Purpose - The objective of this research is to a) examine the effects of online reviews, posted on online distribution channels, on the change of consumers' attitudes and booking intention by distinguishing three types of online review valence: positive, negative and neutral review valence, and b) to investigate the combined effect of the inclination of online review and perceived usefulness of reviews on consumers' attitude change. Research design, data, and methodology - An experimental design was used by creating a mimicked hotel company's website and online reviews extracted from several online distribution channels such as online travel agencies (OTAs). A total of 414 respondents were randomly assigned to a type of review valence. Results - The results showed that the valence of positive reviews has a significant effect on the positive change of attitude and booking intention. However, the effect of the valence of negative reviews on the change of booking intention was not statistically significant compared to that of the valence of neutral reviews. Conclusions - The results offer some insights into the effect of online reviews on consumers' decision making processes and have important managerial implications for companies that operate online distribution channels in terms of their online marketing and the distribution of service products.

This study examined young children's beliefs about trait stability based on trait type and valence. Participants included 120 children (40 three-year-olds, 40 four-year-olds, and 40 five-year olds) recruited from 3 day-care-centers and 1 kindergarten in Seoul and Kyung-Ki province. Results revealed that young children's understanding of traits differed based on trait type and valence. Children demonstrated a strong belief that social-intention traits are more stable and harder to change when compared to internal-state traits. Young children's beliefs on trait stability were also strongly influenced by trait valence. They believed that negative traits are more likely to change for the better while positive traits have greater stability and are less likely to change over time.

This study examines the factors influencing custom officers' readiness for the Sales and Service Tax (SST) implementation in Malaysia. Specifically, this study examines the factors stipulated in the Theory of Organisational Readiness namely, change valence, task knowledge, and resource availability on the customs officers' readiness in terms of change commitment and change efficacy for SST 2.0 implementation. This study utilizes the questionnaire survey distributed to employees of the Royal Malaysian Customs Department (RMCD) that have undergone a significant change of tax regime from Goods and Service Tax (GST) to SST 2.0. The results show that all three factors significantly and positively influence the customs officers' readiness in terms of change commitment and change efficacy for SST 2.0 implementation in Malaysia. The findings in this study indicate that to ensure smooth SST 2.0 implementation, it is important for the customs department to give attention to the perception of the officers and provide the necessary resources. The findings of this study could assist RMCD and other custom agencies to take into account factors that influence readiness for change which indirectly affect job responsibility and performance of the organization.

The CO molecules adsorbed on Ni(111) surface is studied in the cluster approximation employing EH method with self-consistent charge iteration. The effect of CO coverage is simulated by allowing the variation of valence state ionization potentials of each Ni atom in model cluster according to the self-consistent charge iteration method. The CO coverage dependent C-O stretching frequency shift, adsorption site conversion, and metal work function change are attributed to the charge transfer between metal surface and adsorbate. For CO/Ni(111) system, net charge transfer from Ni surface to chemisorbed CO molecules makes surface Ni atoms be more positive with increasing coverage, and lowers Ni surface valence band. This leads to a weaker interaction between metal surface valence band and Co $2{\pi}^{\ast}$ MO, less charge transfer to a single CO molecule, and the bule shift of C-O stretching frequency. Further increase of coverage induces the conversion of 3-fold site CO to lower coordination site CO as well as the blue shift of C-O stretching frequency. This whole process is accompanied by the continuous increase of metal work function.

The study of loss aversion has progressed. Specifically, Brenner et al. (2007) distinguished between possession loss aversion (PLA) and valence loss aversion (VLA) and explained PLA is the loss of cash or spot goods (money, apartment) and that VLA is the loss of tentative value (opportunity of oversea study, coupon). Also, they explored how the tendency of loss aversion was different between when possession loss was salience and when valence loss was outstanding. But, in our everyday life, it is more common that people face some economic situation where the gain and loss between possession and valence are competing. And, in this situation, they usually choose a better option based on their ordinary mind-set or self-focus rather than on which option has more benefit. Therefore, present research is that whether the tendency of loss aversion is different based on one's ordinary self-focus. Concretely, after priming promotion focus vs. prevention focus, participants should decide whether present occupation changes or not when gain and loss between possession and valence compete (income increase but oversea study chance decrease or income decrease but oversea study chance increase). As a result, there are more rate of changing job in promotion focusing condition than prevention focusing condition based on positive change irrespective of possession or valence. This result can have implication for marketing, consumer and advertisement psychology.

Ferroelectric $HoMnO_3$ thin films were deposited on the Si(100) substrate at $700^{\circ}C$ for 2 hrs by metalorganic chemical vapor deposition (MOCVD) and post-annealed at 850oC by rapid thermal process (RTP). Electrical properties and crystalline phases of $HoMnO_3$ thin films were investigated as a function of postannealing time. Single phase of hexagonal symmetry with c-axis preferred orientation was obtained from $HoMnO_3$ thin films post-annealed at $850^{\circ}C$ for 5 min, while the c-axis preferred orientation was decreased with the increase of post-annealing time, and the thin films post-annealed at $850^{\circ}C$ for 15 min showed the mixture phases of hexagonal and orthorhombic symmetry. P-E (Polarization-Electric field) hysteresis loop of ferroelectric $HoMnO_3$ thin films was observed only for the single phase of hexagonal symmetry, but that was not observed for the mixture phases of the hexagonal and orthorhombic symmetry, which was discussed with the bond valence of Mn ion of crystalline phase. Leakage current density was dependent on the microstructure of thin films as well as the change of valence of Mn ion.

The variation of the stable region of arsenic compounds in aqueous environment with temperature has been investigated by constructing the Pourbaix diagram of arsenic at different temperatures. The standard potential corresponding to the boundary between arsenic compounds with different charge valence was estimated to be decreased with temperature, which means the stability of arsenic compound with +5 charge valence increases. The distribution diagram of the most highly oxidized arsenic compound showed that arsenic acid is formed at higher pH and arsenate is generated at lower pH as temperature rises. The aquatic toxicity due to arsenic compounds was considered to be decreased with temperature in the neutral pH condition based on the $LD_T$ value defined in this study.

Recently, nonthermal bioplasma has been attracted by researchers due to their potentials to modulate cellular functions resulting in changes of biomolecular electron band structures as well as cell morphologies. We have investigated the secondary electron emission characteristics from the surface of the erythrocyte, i.e., red blood cell (RBC) with and without the nonthermal bioplasma treatment in morphological and biomolecular aspects. The morphologies have been controlled by osmotic pressure and biomolecular structures were changed by well known reactive oxygen species. Ion-induced secondary electron emission coefficient have been measured by using gamma-focused ion beam (${\gamma}$-FIB) system, based on the quantum mechanical Auger neutralization theory. Our result suggests that the nonthermal bioplasma treatment on biological cells could result in change of the secondary electron emission coefficient characterizing the biomolecular valence band electron energy structures caused by the cell morphologies as well as its surface charge distributions.
