This study applies two variables in the measurement of company patent deployment strategies: patent family depth and earn plan ratio. Patent family depth represents the degree to which certain fields and markets are valued by the patent owner. Earn plan ratio defined as the ratio of the number of patent forward citations to patent family size. Earn plan ratio indicates the degree to which a patent family could be cited by later innovators and competitors. This study applies a logistic regression model in the analysis LED industry data. The results demonstrate that patent value has a positive relationship with the patent family depth, and earn plan ratio.

This study employs a panel threshold regression model to test whether the patent h–index has a threshold effect on the relationship between patent citations and market value in the pharmaceutical industry. It aims to bridge the gap in extant research on this topic. This study demonstrates that the patent h–index has a triple threshold effect on the relationship between patent citations and market value. When the patent h–index is less than or equal to the lowest threshold, 4, there is a positive relationship between patent citations and market value. This study indicates that the first regime (where the patent h–index is less than or equal to 4) is optimal, because this is where the extent of the positive relationship between patent citations and market value is the greatest.
The glass ceiling problem has been a hot topic in research of female senior leadership in companies, especially in e-commerce companies. It has become a worldwide debate of which promote barriers and weakness for female managers are discussed. China has present a sharp rise this year from 25% to 51% female senior management position, however, by sampling survey in this study, we found that female senior managers still in a disadvantageous position. This study sampling investigated 200 China listed companies in e-commerce industry to explore the pattern of female senior business leadership. The results in this study reveal that 75% of sample companies held no more than 3 female senior managers, 97% of female members in board of directors. By studying patterns of female senior manager leadership, this study provides evidences of status quo of Chinese female senior managers and therefore draws attention to glass ceiling problems at the highest levels within China listed companies.

PURPOSE: This study aimed to examine differences in depressive symptoms between urban and rural workers in mainland China and to identify community factors that could contribute to such residential differences. METHODS: This study used nationally representative data from the 2014 China's Labor Force Dynamic Survey. Data were collected through face-to-face interviews on a sample of 22,073 participants from 29 provinces of China, including 15,098 rural workers (Mage = 44.92, standard deviation ( SD) = 14.85) and 6,975 urban workers (Mage = 43.28, SD = 13.62). Mediators included community cohesion, foreseeable community threat, supportive network size and medical benefit coverage. Mediation analyses were conducted using Hayes' SPSS Macro Process for multiple mediators. RESULTS: Urban participants reported fewer depressive symptoms than their rural counterparts. Lower levels of community cohesion, higher community foreseeable threat and poorer medical coverage were related to fewer depressive symptoms. Rural-urban differences were mediated by community cohesion ( B = -0.12, p < .01), foreseeable community threat ( B = -0.08, p < .01) and medical benefit coverage ( B = 0.25, p < .01). CONCLUSION: This study sheds light on distinctive roles of community factors in explaining rural-urban differences in depressive symptoms. Policies or programs should be designed to promote strengths and address weaknesses in rural communities.
