The Forecast of Chinese Three Industrial Structures Under Grey Combination Data Model
Niannian Jia,Yanyou Chai
Journal of Modern Mathematics and Statistics , 2012,
Abstract: At present, China is at a crucial changing period from the second step strategic target to the third step strategic target. To forecast the future trend of the three industrial structures scientifically and to draw up the development target of industry rationally have great significance in optimizing the allocations of resources and achieving sustained economic growth. In this study, we combine the spherical projection with the grey model and present a new method to forecast Chinese 3 industrial structures. Compared with the actual data, we attest to that the model presented by this study can forecast Chinese 3 industrial structures quite accurately, reflect the Chinese three industrial structures mechanism and have rational and effective functions for analyzing trend and forecasting.
A Class of Variable Payment Life Insurance Actuarial Model with the Stochastic Interest Rate under the Weibull Distribution of Death
Niannian Jia,Yanhui Ji
Journal of Modern Mathematics and Statistics , 2012, DOI: 10.3923/jmmstat.2011.80.83
Abstract: Owing to the steady fluctuation of the Wiener process and the sudden disturbance of the negative binomial distribution, we proposed an interest force accumulation function model with a Wiener process and a negative binomial distribution. We built a n-years variable payment life insurance Actuarial Model with this interest force accumulation function. Meanwhile, we obtained the level net premium based on the semi-continuous variable payment life insurance policy with the hypothesis of Weibull mortality. Finally, we simulated model in a numerical example with Matlab and concluded the impact of different parameters upon the level net premium. That further verified the feasibility of the model.
Ruin Probabilities of Double Compound Poisson Risk Model under Proportional Reinsurance and Interest Force
Jia Niannian,Xia Yunfan
Journal of Modern Mathematics and Statistics , 2012, DOI: 10.3923/jmmstat.2012.10.13
Abstract: The researchers introduced interest force and reduced the risk of the insurance company with the proportional reinsurance under double compound Poisson risk model. Differential-Integral equations of ruin probabilities in finite and infinite time were provided. These conclusions have theoretical significance for the insurance company measuring ruin risk.

Abstract: 摘要 通过整合社会学习理论和地位理论,以303名员工为被试,采用两个时点上的主管领导和员工自评的配对数据,分析了组织内不同层级的管理者榜样作用对于员工文化认同的影响及作用大小,并进一步探析了CEO榜样作用和直接上级榜样作用有效发挥的企业文化情境。研究结果表明,CEO榜样作用、直接上级榜样作用均与员工企业文化认同有显著的正向关系,且CEO榜样作用对员工企业文化认同的影响要大于直接上级的榜样作用;宗族式文化对CEO榜样作用与员工企业文化认同的关系起正向调节作用;层级式文化对CEO榜样作用与员工企业文化认同的关系起正向调节作用,对直接上级榜样作用与员工企业文化认同的关系起负向调节作用
Impact of Individual-Level Social Capital on Quality of Life among AIDS Patients in China
Ying Ma, Xia Qin, Ruoling Chen, Niannian Li, Ren Chen, Zhi Hu
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0048888
Abstract: Background With growing recognition of the social determinants of health, social capital is an increasingly important construct in international health. However, the application of social capital discourse in response to HIV infection remains preliminary. The aim of this study was to assess the impact of social capital on quality of life (QoL) among adult patients with acquired immune deficiency syndrome (AIDS). Methods A convenient sample of 283 patients receiving antiretroviral treatment (ART) was investigated in Anhui province, China. QoL data were collected using the Medical Outcomes Study HIV Survey (MOS-HIV) questionnaire. Social capital was measured using a self-developed questionnaire. Logistic regression models were used to explore associations between social capital and QoL. Results The study sample had a mean physical health summary (PHS) score of 50.13±9.90 and a mean mental health summary (MHS) score of 41.64±11.68. Cronbach's α coefficients of the five multi-item scales of social capital ranged from 0.44 to 0.79. When other variables were controlled for, lower individual levels of reciprocity and trust were associated with a greater likelihood of having a poor PHS score (odds ratio [OR] = 2.02) or PHS score (OR = 6.90). Additionally, the factors of social support and social networks and ties were associated positively with MHS score (OR = 2.30, OR = 4.17, respectively). Conclusions This is the first report to explore the effects of social capital on QoL of AIDS patients in China. The results indicate that social capital is a promising avenue for developing strategies to improve the QoL of AIDS patients in China, suggesting that the contribution of social capital should be fully exploited, especially with enhancement of QoL through social participation. Social capital development policy may be worthy of consideration.
Study on the Normal and Skewed Distribution of Isometric Grouping  [PDF]
Zhensheng Jia, WenKai Jia
Open Journal of Statistics (OJS) , 2012, DOI: 10.4236/ojs.2012.24056
Abstract: Because of thinking only the number of numbers but not fitting function, it would be adequate to take further afield when calculating group numbers with empirical formula. We have proved the three theorems based on studying the normal distribution, and then reach the conclusion that there is a better method to do the same work. The method is simpler and more practical than empirical method and also works well with any skewed distribution.
Existence of Ordered Solutions to Quasilinear Schr?dinger Equations with General Nonlinear Term  [PDF]
Jia Wu, Gao Jia
Journal of Applied Mathematics and Physics (JAMP) , 2018, DOI: 10.4236/jamp.2018.64068
Abstract:
In this paper, the existence of a pair of ordered solutions for the following class of equations in \"\" \"\" (1) was studied. A bounded (PS) (Palais-Smale) sequence was constructed and the related variational principle was used to prove the existence of the positive solution. The existence of the ordered solutions is finally found.
Approximate Kepler’s Elliptic Orbits with the Relativistic Effects  [PDF]
Leilei Jia
International Journal of Astronomy and Astrophysics (IJAA) , 2013, DOI: 10.4236/ijaa.2013.31004
Abstract:

Beginning with a Lagrangian, we derived an approximate relativistic orbit equation which describes relativistic corrections to Keplerian orbits. The critical angular moment to guarantee the existence of periodic orbits is determined. An approximate relativistic Kepler’s elliptic orbit is illustrated by numerical simulation via a second-order perturbation method of averaging.

Strategic Positioning: Key Point of Business Transformation
—Revelation of Xiangeqing’s Transition
 [PDF]

Ying Jia
Open Journal of Social Sciences (JSS) , 2015, DOI: 10.4236/jss.2015.310010
Abstract: Explicit strategic positioning is the most important factor to motivate the development of an enterprise. Based on the specific condition for an enterprise, a unique strategy could be one competitive advantage for it. Furthermore, for the enterprises who want to change their traditional operating styles, a strategy that follows up with current environment is necessary. This essay tries to discuss the importance of specific and renewable strategic positioning based on the failed transformation of Xiangeqing and provide some suggestions for the main problems.
Coordination of Supply Chain under the Revenue Sharing-Advertising Cost Sharing Contract  [PDF]
Meng Jia
Journal of Service Science and Management (JSSM) , 2017, DOI: 10.4236/jssm.2017.103024
Abstract: In this article, we study a two-echelon supply chain with a single manufacturer and a single retailer. In the case of advertising investment affecting the market demand, we use the theory of game theory, and respectively discuss the coordination of general revenue sharing contract and revenue sharing-advertising cost sharing contract. The results show that: the general revenue sharing contract cannot achieve supply chain coordination. However, revenue sharing-advertising cost sharing contract in a specific form can achieve supply chain coordination. And in the appropriate revenue sharing contract parameters, it can also achieve a win-win situation between the two sides.
