为了探讨食品抽检中菌落总数指标复检的可能性,通过对水活度较低的预包装食品乳粉、营养米粉、燕麦片、膨化食品、蜂蜜进行菌落总数测定,对低水分活度预包装食品菌落总数指标的稳定性进行分析。结果表明,同一批次、同一储存条件的未开封预包装食品在不同保存周期内菌落总数在统计学上无显著差异,本研究结果可为低水分活度预包装菌落总数的复查可行性提供参考依据。 相似文献

We examine call option rights as a contractual clause in international joint ventures (IJVs) and propose that the assignment of the call option right in an IJV is determined by certain ex ante asymmetries between the partners. Results show that between the two partners in an IJV, the firm with greater complementarity with the venture and greater prior IJV experience is more likely to hold the call option right; in addition, the firm's contractual choice on the call option right and its ownership choice on a greater initial equity stake are substitutive. Our focus on explicit call options advances the real options theory of collaborative agreements, and our results also highlight that option rights be considered an important part of alliance design.

We develop a dynamic valuation model of the hedge fund seeding business by solving the consumption and portfolio-choice problem for a risk-averse manager who launches a hedge fund through a seeding vehicle. This vehicle, i.e. fees-for-seed swap, specifies that a strategic partner (seeder) provides a critical amount of capital in exchange for participation in the funds revenue. Our results indicate that the new swap not only solves the serious problem of widespread financing constraints for new and early-stage funds (ESFs) managers, but can be highly beneficial to both the manager and the seeder if structured properly. 相似文献

Consumers become indecisive when facing too many choices. Economic analysis suggests that when a decision involves uncertain outcome, can be delayed and is irreversible, there will be a real option in the cost–benefit analysis. For example, the option to keep alive a consumer's purchasing decision has a significant value. It allows the consumer to take advantage of any future advantageous deals while avoiding the bad choices. This renders the consumer more hesitant. When a consumer decides to exercise his buying decision, he demands a compensation for the loss of this option. Hence, the benefits of a purchase must be over and above its costs by a wide margin (the option value). Data from a survey at a Turkish university on hypothetical purchase decisions confirmed the existence of this real option. We conclude with marketing policy recommendations and future research directions. Connection to the Prospect Theory is briefly explored.Note: Although the 3rd person singular pronoun he/his was used throughout to describe the consumer, he was intended to be gender-neutral. 相似文献

Increasing demand for cereals produced from limited natural resources stimulated the Green Revolution in grain crops like wheat and rice. But the gap between potential and actual production continues. Concerns about sustainability, and the social and technical shortcomings of the Green Revolution, have triggered a number of alternative crop production strategies. One, in particular, the so-called System of Rice Intensification (SRI), is attracting attention by governments, civil society organizations and farmers in Asia and elsewhere. 相似文献
