Historic Achievements in Developing Human Resources and Social Security

Guided by the state policy of reform and opening to the outside world, the Chinese Government has, by dint of hard work over the past three decades, by and large accomplished the task of building up a human resources and social security system. Good enough to serve China＇s goal of developing a socialist market economy, this system has contributed to the national endeavor to ensure and improve people＇s livelihood and to safeguard the stability of the reform-and-opening undertakings.

Measurement Research Based on Bayesian Structural Equation Cognitive Model

The Bayesian structural equation model integrates the principles of Bayesian statistics, providing a more flexible and comprehensive modeling framework. In exploring complex relationships between variables, handling uncertainty, and dealing with missing data, the Bayesian structural equation model demonstrates unique advantages. Therefore, Bayesian methods are used in this paper to establish a structural equation model of innovative talent cognition, with the measurement of college students’ cognition of innovative talent being studied. An in-depth analysis is conducted on the effects of innovative self-efficacy, social resources, innovative personality traits, and school education, aiming to explore the factors influencing college students’ innovative talent. The results indicate that innovative self-efficacy plays a key role in perception, social resources are significantly positively correlated with the perception of innovative talents, innovative personality tendencies and school education are positively correlated with the perception of innovative talents, but the impact is not significant.

Analysis on the Spatio-Temporal Changes of Sustainable Land Use in Tibet

By constructing evaluation indicator system of sustainable land use of Tibet from three aspects of ecological environment, economic development, resources and social advancement, this article studies the following contents respectively in two dimensions of time and space： the changes of sustainable land use of Tibet in recent 20 years and spatial characteristics of sustainable land use of Tibet in 2002. The following conclusions can be drawn from evaluation results .① With regard to com- prehensive evaluation value of sustainable land use, the trend of Tibet sustainable land use evaluation values from 1983 to 2002 are very close to the comprehensive evaluation values of ecological environment, which is up trend; ② sustainable utilization degree of land use in eastern region of Tibet is much higher than that of western region. ③ the sustainable land use evaluation value of Nyingtri County is the highest, and the counties with relatively higher land sustainable use values include Lhasa, Lhoka, Chamdo. While Nakchu, Ngari, Shigatse counties have the relatively lower evaluation values; ④ By analyzing each evaluation indicator＇s weight on sustainable land use, it can be concluded that the key limiting factors of sustainable Tibet land resource utilization are land desertification, grassland degradation and low economic level.

Is bigger better？ Male body size affects wing-borne courtship signals and mating success in the olive fruit fly, Bactrocera oleae （Diptera： Tephritidae）

Variations in male body size are known to affect inter- and intrasexual selection outcomes in a wide range of animals. In mating systems involving sexual signaling before mating, body size often acts as a key factor affecting signal strength and mate choice. We evaluated the effect of male size on courtship displays and mating success of the olive fruit fly, Bactrocera oleae （Diptera： Tephritidae）. Wing vibrations performed during successful and unsuccessful courtships by large and small males were recorded by high-speed videos and analyzed through frame-by-frame analysis. Mating success of large and small males was investigated. The effect of male-male competition on mating success was evaluated. Male body size affected both male courtship signals and mating outcomes. Successful males showed wing-borne signals with high frequencies and short interpulse intervals. Wing vibrations displayed by successful large males during copulation attempt had higher frequencies over smaller males and unsuccessful large males. In no-competition conditions, large males achieved higher mating success with respect to smaller ones. Allowing large and small males to compete for a female, large males achieve more mating success over smaller ones. Mate choice by females may be based on selection of the larger males, able to produce high-frequency wing vibrations. Such traits may be indicative of ＂good genes,＂ which under sexual selection could means good social-interaction genes, or a good competitive manipulator of conspecifics.

Capacities in Facing Natural Hazards: A Small Island Perspective

Isolated communities on small islands are often characterized as vulnerable and marginalized. We studied the recent history of Laingpatehi, a village on Ruang Island off the north coast of Sulawesi, Indonesia to show that the marginalization-vulnerability nexus can be offset by capacity and social cohesion to enable sustainable livelihoods. The island has been impacted by volcanic eruptions,earthquakes, and competition for marine resources from mainland-based fishermen. The community has shown a remarkable ability to cope and prosper in the face of a series of external hazards. We used a sustainable livelihoods approach to identify the assets that enabled the villagers to cope. Strong social cohesion was central to the ability to organize the community and confront hazards. A diversified livelihood strategy drawing on the small island environment and its coastal and marine resources, income generating activities in a distant satellite village, and significant remittances from employment in other parts of Indonesia underpinned people’s capacities to face hazards.Government assistance played a supporting role. The case of Laingpatehi demonstrates how remoteness, rather than being a source of vulnerability, can provide access to existing resources and facilitate innovation. Disaster risk reduction strategies should focus more on reinforcing these existing capacities to deal with hazards and less on physical protection and postdisaster responses.

Work-family conflict and organizational citizenship behavior： the role of job satisfaction and decision authority

Drawing upon the conservation of resources theory （Hobfoll, Am Psychol 44：513- 524, 1989）, social exchange theory （Blau, Exchange and power in social life, 1964） and the job demand-control model （Karasek, Adm Sci Q 24：285-308, 1979）, this study uncovers the theoretical mechanism that explains the relationship between work- family conflict and organizational citizenship behavior （OCB）. First, this study focuses on how employee job satisfaction mediates the relationship. Then, we investigate the moderating role of decision authority in, the mediated relationsip. We employ three-wave data collected from 324 employees in 102 teams to test our hypotheses. Aesults of hierarchical linear modeling （HLM） first shows that job satisfaction mediates the relationship between work interference with family （WIF） and OCB. In addition, employees＇ decision authority moderates the direct effect of WlF on OCB. Specifically, the negative relationship between WlF and OCB is stronger when employees＇ decision authority is high. Moreover, decision authority moderates the indirect effect of WIF on OCB via job satisfaction. Specifically, the negative relationship between WlE and job satisfaction is weaker when employees＇ decision authority is high. The results suggest that organizations should give employees enough decision authority over their work, as a high level of decision authority may act as a double-edged sword regarding critical organizational outcomes.
