    Description: Firms with higher asset growth rates subsequently experience lower stock returns in international equity markets, consistent with the U.S. evidence. This negative effect of asset growth on returns is stronger in more developed capital markets and markets where stocks are more efficiently priced, but is unrelated to country characteristics representing limits to arbitrage, investor protection, and accounting quality. The evidence suggests that the cross-sectional relation between asset growth and stock return is more likely due to an optimal investment effect than due to overinvestment, market timing, or other forms of mispricing.

    Description: This article aims to scrutinize an emerging and prominent type of work team in organizations: the spontaneous virtual team (SVT). Despite the promising benefits an SVT can provide, it is confronted with great challenges throughout its lifecycle. In this article, we first highlight the unique structure and characteristics of SVTs as compared to other conventional types of work teams. Furthermore, we decompose the lifecycle of an SVT into three stages. We then use interview data among SVT managers and participants across several industries to analyze the challenges, corresponding solutions, and the role of information and communication technologies in each of the three stages. Understanding the emerging SVTs will be of salient value to professionals and corporate executives who are interested in finding effective technology-enabled means and work patterns to improve organizational work performance. The current work can also serve as a basis for future academic research on exploring the SVT phenomenon.

    Description: Online feedback systems (OFSs) are increasingly available on online shopping websites; they allow consumers to post their ratings and consumption reviews for products. We employed motivation theory and a goal attainment perspective to model a set of motivating and inhibiting factors that could influence a consumer's intention to contribute to an OFS. Our experiment, which involved 168 university students, showed that a consumer's intention to contribute product reviews is influenced by perceived satisfaction gained in helping other consumers, perceived satisfaction gained in influencing the merchant, perceived probability of enhancing self-image, and perceived executional costs. In addition, the presence of an economic rewarding mechanism was found to promote a contribution when a consumer's perceived probability of enhancing self-image was relatively high or when perceived cognitive cost was relatively low. Implications of our findings are discussed.

    Description: Issue Title: In Memory of Horst Marschner This study aimed to determine the effect of arbuscular mycorrhizal (AM) fungi and phosphorus (P) supply levels on [beta]-carotene concentrations in sweet potato (Ipomoea batatas L.) tubers. Two commercial AM fungal isolates of Glomus intraradices (IFP Glintra) and Glomus mosseae (IFP Glm) which differ in their life cycles were used. Sweet potato plants were grown in a horizontal split-root system that consisted of two root compartments. A root-free fungal compartment that allowed the quantification of mycelial development was inserted into each root compartment. The two root compartments were inoculated either with the same or with different AM isolates, or remained free of mycorrhizal propagules. Each fungal treatment was carried out in two P supply levels. In the low P supply level, mycorrhizal colonization significantly increased [beta]-carotene concentrations in sweet potato tubers compared with the non-mycorrhizal plants. Glomus intraradices appeared to be more efficient in increasing [beta]-carotene concentrations than G. mosseae. Dual inoculation of the root system with the two mycorrhizal fungi did not result in a higher increase in tuber [beta]-carotene concentrations than inoculation with the single isolates. Improved P nutrition led to higher plant tuber biomass but was not associated with increased [beta]-carotene concentrations. The results indicate a remarkable potential of mycorrhizal fungi to improve [beta]-carotene concentrations in sweet potato tubers in low P fertilized soils. These results also suggest that [beta]-carotene metabolism in sweet potato tubers might be specifically activated by root mycorrhizal colonization.[PUBLICATION ]

    Description: Polystyrene (PS)–γ‐methacryloxypropyl trimethoxy silane (MPTMS) copolymer/zirconia (ZrO) nanohybrid materials were successfully prepared by the combination of solvothermal and synthesis methods, in which the comonomer was used as chemical bonding agent between the nanoparticles and the matrix, and acetylacetone (AcAc) was used as a size control agent of ZrO in the PS matrix. Then, a new transparency film with a relatively high refractive index (1.72) was successfully obtained, in which ZrO could be dispersed well in the PS–MPTMS matrix. Field emission scanning electron microscopy images indicated that AcAc was helpful in the dispersion of the nanoparticles, and smaller ZrO particles with no aggregation were obtained in the PS–MPTMS matrix. The structure and thermal properties of the hybrid films were investigated by Fourier transform infrared spectroscopy and thermogravimetric analysis, and the surface properties were also examined. © 2013 Wiley Periodicals, Inc.

    Description: Poly(ethylene glycol)-block-poly(d,l-lactic acid) (PEG-b-PLA) micelles are nanocarriers for poorly water-soluble anticancer agents and have advanced paclitaxel (PTX) to humans due to drug solubilization, biocompatibility, and dose escalation. However, PEG-b-PLA micelles rapidly release PTX, resulting in widespread biodistribution and low tumor exposure. To improve delivery of PTX by PEG-b-PLA micelles, monodisperse oligo(l-lactic acid), o(LA)8 or o(LA)16, has been coupled onto PTX at the 7-OH position, forming ester prodrugs: o(LA)8-PTX and o(LA)16-PTX, respectively. As expected, o(LA)n-PTX was more compatible with PEG-b-PLA micelles than PTX, increasing drug loading from 11 to 54%. While in vitro release of PTX was rapid, resulting in precipitation, o(LA)n-PTX release was more gradual: t1/2 = 14 and 26 h for o(LA)8-PTX and o(LA)16-PTX, respectively. Notably, o(LA)8-PTX and o(LA)16-PTX in PEG-b-PLA micelles resisted backbiting chain end scission, based on reverse-phase HPLC analysis. By contrast, o(LA)8-PTX and o(LA)16-PTX degraded substantially in 1:1 acetonitrile:10 mM PBS, pH 7.4, at 37 °C, generating primarily o(LA)2-PTX. The IC50 value of o(LA)2-PTX was ∼2.3 nM for A549 human lung cancer cells, equipotent with PTX in vitro. After weekly IV injections at 20 mg/kg as PEG-b-PLA micelles, o(LA)8-PTX induced tumor regression in A549 tumor-bearing mice, whereas PTX delayed tumor growth. Surprisingly, o(LA)8-PTX caused less toxicity than PTX in terms of change in body weight. In conclusion, o(LA)n acts as a novel promoiety, undergoing backbiting conversion without a reliance on metabolizing enzymes, and o(LA)n-PTX improves PTX delivery by PEG-b-PLA micelles, providing a strong justification for clinical evaluation.
