Family Business Succession in Hong Kong： The Case of Yung Kee

Frontiers of Business Research in China 2013年第3期7卷 433-460页

This case study examines the succession of Chinese family business in Hong Kong, drawing upon theories of the firm. More specifically, it utilizes capabilities theories, property rights economics and Neo-Confucianism to understand management disputes and infighting among the members in a Chinese family business in Hong Kong. This paper will argue that the founder of a Chinese business firm in Hong Kong is able to lead his or her offspring to create a dynamic enterprise via charismatic leadership and family rules embedded in traditional Chinese values. However, these two strategic assets disappear following the passing away of the founder as well as the emergence of new social values. When the founder passes on the enterprise to his or her offspring using more or less the equal inheritance system, the traditional Chinese value is unable to enforce the leader＇s will to consolidate the strengths of the second generation family members to maintain the founder＇s business. Furthermore, when the business is owned by all family members, property rights of the firm become unclear. Without effective enforcement of traditional Chinese values and with collective ownership rights, some family members will have the incentive to capture the economic rent that is shared by all members. In other words, some family members behave opportunistically or even cheat in order to capture economic gains in the public domain. High monitoring and enforcement costs in the form of court battle and endless disputes will occur. Rent dissipation occurs in the form of deterioration of the quality of the family business. This casestudy is based on Yung Kee, an intemationally well-known roast goose restaurant in Hong Kong as an illustration.

Susceptibility of northern corn rootworm Diabrotica barberi （Coleoptera： Chrysomelidae） to mCry3A and eCry3.1Ab Bacillus thuringiensis proteins

作者： Isaac O. Oyediran Phillip Matthews Narendra Palekar Wade French Jared Conville tony Burd Syngenta Crop Protection LLC Research Triangle Park NC 27709 USA USDA ARS North Central Agricultural Research Laboratory Brookings SD 57006 USA

The susceptibility of the northern corn rootworm Diabrotica barberi （Smith ＆ Lawrence） to mCry3A and eCry3.1Ab proteins derived from Bacillus thuringiensis （Bt） was determined using a diet bioassay. Northern corn rootworm neonates were exposed to different concentrations of mCry3A and eCry3.1Ab, incorporated into artificial diet. Larval mortality was evaluated after 7 d. The mCry3A and eCry3.1 Ab proteins were found to be toxic to the northern corn rootworm larvae. The LCs0 and LC99 values for mCry3A were 5.13 and 2482.31 μg/mL, respectively. For eCry3.1Ab, the LC50 and LC99 values were 0.49 and 213.01 μg/mL. Based on the estimated lethal concentrations, eCry3, lab protein was more efficacious to northern corn rootworm larvae than mCry3A. These lethal concentration values will be used as diagnostic doses for routine annual monitoring for change in susceptibility of field collected northern corn rootworm to mCry3A, and eCry3.1Ab toxins.

Purpose Sled towing has been shown to be an effective method to enhance the physical qualities in youth *** aim of this study was to evaluate the impact of a 6-week sled towing intervention on muscular strength,speed and power in elite youth soccer players of differing maturity *** Seventy-three male elite youth soccer players aged 12-18 years(Pre-Peak Height Velocity[PHV]n = 25;Circa-PHV n = 24;Post-PHV n = 24)from one professional soccer academy participated in this *** assessments(10 m and 30 m),countermovement jump and isometric mid-thigh pull were undertaken before(T1)and after(T2)a 6-week *** training intervention consisted of 6 weeks(2xper week,10 sprints over 20 m distance)of resisted sled towing(linear progression 10%-30%of body mass)during the competitive *** regression models analysed differences between T1 and T2 within each maturity *** There were minimal changes in strength,speed and power(P=0.35-0.80)for each maturity group across the 6-week *** there were changes with greater certainty,they are unlikely to represent real effect due to higher regres-sion to the mean(RTM).Conclusion It appears that a 6-week sled towing training programme with loadings of 10%-30%body mass only maintains physical qualities in elite youth soccer players pre-,circa-,and *** research is required to determine the effectiveness of this training method in long-term athletic development programmes.
