Help Less or Help More —Perceived Intergroup Threat and Out-Group Helping
Tingyan Li,Yufang Zhao
International Journal of Psychological Studies , 2012, DOI: 10.5539/ijps.v4n4p90
Abstract: The present research investigated the relationship between intergroup threat and prosocial actions toward out-group members. We proposed that intergroup threat not only results in direct negative intergroup attitudes and behavior, but also promotes an indirect reduction in out-group helping. Study 1 (N = 54) was conducted in a realistic setting, whereas Study 2 (N = 92) employed an experimental context. Willingness to help (help intent) and monetary donation (help behavior) was compared between the threatening out-group and the non-threatening out-group. The results showed that when intergroup threat was experienced, more help was offered to the non-threatening out-group than the threatening out-group. The findings suggest that perceived intergroup threat attenuates prosocial behavior toward out-group members.

Tingyan Xing, Shang Zhang, Fan Zhang
Journal of Geographic Information System (JGIS) , 2014, DOI: 10.4236/jgis.2014.62012
Abstract:

Geographical Information System (GIS) always plays an integral role in LBS systems. But it comes with technology problems, such as less flexible, low efficiency, no redundancy of existing geographic information of application configuration which has high entry cost. At same time, indoors positioning is attracting more and more attention from research domain where GPS-like systems do not work. By RSSI location fingerprint data that sampling from the actual WSN environment, this article analyzed RF signal propagation characteristics in indoor from the point of view of the indoor positioning, and analyzed some factors that may affect the positioning error, which provided a theoretical basis for the positioning algorithm design and positioning system deployment. The aim of this paper is also to present a lightweight, efficient and scalable microkernel plug-in geospatial information application system and its implementation method for GIS in LBS design and practice. In this paper a software model called Resource loading manager (RLM) is designed. Through the RLM efficient allocation of geographic information resources and security management could be achieved.

Zhihong Lin,Jie Gu,Jin Xiu,Tingyan Mi,Jie Dong,Jyoti Kumar Tiwari
Evidence-Based Complementary and Alternative Medicine , 2012, DOI: 10.1155/2012/692621
Abstract: Traditional Chinese Medicine (TCM) has a 3000 years' history of human use. A literature survey addressing traditional evidence from human studies was done, with key result that top 10 TCM herb ingredients including Poria cocos, Radix polygalae, Radix glycyrrhizae, Radix angelica sinensis, and Radix rehmanniae were prioritized for highest potential benefit to dementia intervention, related to the highest frequency of use in 236 formulae collected from 29 ancient Pharmacopoeias, ancient formula books, or historical archives on ancient renowned TCM doctors, over the past 10 centuries. Based on the history of use, there was strong clinical support that Radix polygalae is memory improving. Pharmacological investigation also indicated that all the five ingredients mentioned above can elicit memory-improving effects in vivo and in vitro via multiple mechanisms of action, covering estrogen-like, cholinergic, antioxidant, anti-inflammatory, antiapoptotic, neurogenetic, and anti-Aβ activities. Furthermore, 11 active principles were identified, including sinapic acid, tenuifolin, isoliquiritigenin, liquiritigenin, glabridin, ferulic acid, Z-ligustilide, N-methyl-beta-carboline-3-carboxamide, coniferyl ferulate and 11-angeloylsenkyunolide F, and catalpol. It can be concluded that TCM has a potential for complementary and alternative role in treating senile dementia. The scientific evidence is being continuously mined to back up the traditional medical wisdom.
Genome-Wide Analysis of the Cyclin Gene Family in Tomato
Tingyan Zhang,Xin Wang,Yongen Lu,Xiaofeng Cai,Zhibiao Ye,Junhong Zhang
International Journal of Molecular Sciences , 2014, DOI: 10.3390/ijms15010120
Abstract: Cyclins play important roles in cell division and cell expansion. They also interact with cyclin-dependent kinases to control cell cycle progression in plants. Our genome-wide analysis identified 52 expressed cyclin genes in tomato. Phylogenetic analysis of the deduced amino sequences of tomato and Arabidopsis cyclin genes divided them into 10 types, A-, B-, C-, D-, H-, L-, T-, U-, SDS- and J18. Pfam analysis indicated that most tomato cyclins contain a cyclin-N domain. C-, H- and J18 types only contain a cyclin-C domain, and U-type cyclins contain another potential cyclin domain. All of the cyclin genes are distributed throughout the tomato genome except for chromosome 8, and 30 of them were found to be segmentally duplicated; they are found on the duplicate segments of chromosome 1, 2, 3, 4, 5, 6, 10, 11 and 12, suggesting that tomato cyclin genes experienced a mass of segmental duplication. Quantitative real-time polymerase chain reaction analysis indicates that the expression patterns of tomato cyclin genes were significantly different in vegetative and reproductive stages. Transcription of most cyclin genes can be enhanced or repressed by exogenous application of gibberellin, which implies that gibberellin maybe a direct regulator of cyclin genes. The study presented here may be useful as a guide for further functional research on tomato cyclins.

Creative Education (CE) , 2012, DOI: 10.4236/ce.2012.37B039
Abstract:

Teaching and Education (T&E) constitute the most important activity in knowledge transfer from generation to generation. This can explain why government organizations consider the training of highly qualified personnel as one of the most important criteria in the selection of research and development (R&D) grant applications. A university professor should thus not only play the role of researcher, but also that of teacher. T&E and R&D combine to form an inseparable relationship for university professors. By shooting for excellence in T&E, we could get a new perception of a familiar field or initiate a brand new field altogether, which would in turn enhance our research. The quest for excellence in R&D leads to deeper and better understanding of materials taught, and progress in R&D enriches our T&E endeavors. Here, the author shares a beneficial experience from T&E to R&D.

A Causality Analysis of Coal Consumption and Economic Growth for China and India  [PDF]
Jinke Li, Zhongxue Li
Natural Resources (NR) , 2011, DOI: 10.4236/nr.2011.21007
Abstract: China and India are the two countries with the strongest economic growth in the world. Meanwhile they consume much of the global coal to fuel their economic development. With coal burning as a major factor contributing to global greenhouse gas emissions, China and India are confronted with a dilemma of economic growth and environment protection. Will coal consumption reduction cause economic shocks? Is there a causal relationship between coal consumption and economic growth in China and India? In this paper Granger causality tests were used to examine the relationship between coal consumption and GDP in China and India, using data for the period from 1965 to 2006. It was found that a unidirectional causality from GDP to coal consumption existed in China while a unidirectional causality from coal consumption to GDP did in India. Therefore, developing cleaner and more efficient technologies is essential to reduce their CO2 emissions to reach sustainable development.
An Investigation and Analysis of Information Overload in Manager's Work  [PDF]
Tao Li, Min Li
iBusiness (IB) , 2011, DOI: 10.4236/ib.2011.31008
Abstract: The problem of information overload in management field has been receiving increasing attention, while there are less empirical researches now. This paper proposes a conceptual model and some operational variables, in which information overload is as an intervening variable between the factors of causes and impacts. An investigation and analysis has been conducted from a selected sample of managers. This research suggests that work efficiency and work quality are both not strongly connected with information overload. We also find that the main causes of information overload are the work interruption and work time pressure but the amount of information.
