Worker Recruiting with Favoritism and Bribery  [PDF]
Gen Chen, Jun Tang
Theoretical Economics Letters (TEL) , 2015, DOI: 10.4236/tel.2015.53048
Abstract: This paper discusses the corruptive action widespread in the organizations’ worker recruiting: favoritism and bribery. The managers of the firm are actually able to discern the type of the productivity of the job-seekers, but they utilize the information advantage through the two types of misconduct—favoritism and bribery, at the expense of the profit share of the principal (the owner) and the workers’ wage rent. The key conclusion is drawn from this paper as follows: neither the intensity of favoritism nor the wage level matters in determining whether there’s profit or loss in the firm, whereas the key variable is the relative situation of exterior labor market.
The Influence of Female Executives on Corporate Behavior and Performance: A Review  [PDF]
Meng Tang, Jun Xu
Journal of Human Resource and Sustainability Studies (JHRSS) , 2015, DOI: 10.4236/jhrss.2015.33018
Abstract: In recent years, the quantity of female executives in the companies is rising, some countries even raising a mandatory requirement about the proportion of female executives on the company. Women are increasingly attracting the attention of theory and practice fields, so does the discussion of the role of senior women. This article reviews the research about how female executives influence the corporate behavior and performance from the perspective of finance and non-finance, analyses the deficiency of related research and points out the direction for future research.
Nurse Staff Allocation in a Multi-stage Queuing System with Patients’ Feedback Flow for an Outpatient Department  [PDF]
Huabo Zhu, Jiafu Tang, Jun Gong
iBusiness (IB) , 2013, DOI: 10.4236/ib.2013.53B019
Abstract:

A general multi-stage queuing system model with patients’ feedback flow is developed to address the behavior of patients’ flow in an Outpatient Department (OD) in a hospital. The whole process includes registration, diagnosis, chemical examination, payment, and medicine-taking. Focusing on nurse resources, the formulas of performance indicators such as patient waiting times and nurse idle times are derived by using the system parameters. A mathematical programming model is developed to determine how many nurses should be allocated to each stage to minimize the total costs of patient waiting times and nurse idle times. The neighborhood search combined Simulated Annealing (NS-SA) is developed to solve the model, which is essentially a natural number decomposition problem. Numerical experiments are conducted to analyze the discipline of nurse allocation and the impact of patient arrival rates and the probability of patient’s feedback flow on the system costs. The research results will be helpful for hospital managers to make decisions on allocation of nurse staff in practice.

A Model of DNA Repeat-Assembled Mitotic?Chromosomal Skeleton
Shao-Jun Tang
Genes , 2011, DOI: 10.3390/genes2040661
Abstract: Despite intensive investigation for decades, the principle of higher-order organization of mitotic chromosomes is unclear. Here, I describe a novel model that emphasizes a critical role of interactions of homologous DNA repeats (repetitive elements; repetitive sequences) in mitotic chromosome architecture. According to the model, DNA repeats are assembled, via repeat interactions (pairing), into compact core structures that govern the arrangement of chromatins in mitotic chromosomes. Tandem repeat assemblies form a chromosomal axis to coordinate chromatins in the longitudinal dimension, while dispersed repeat assemblies form chromosomal nodes around the axis to organize chromatins in the halo. The chromosomal axis and nodes constitute a firm skeleton on which non-skeletal chromatins can be anchored, folded, and supercoiled.
A Model of Repetitive-DNA-Organized Chromatin Network of Interphase Chromosomes
Shao-Jun Tang
Genes , 2012, DOI: 10.3390/genes3010167
Abstract: During interphase, chromosomes are relatively de-condensed in the nuclear space. Interphase chromosomes are known to occupy nuclear space in a non-random manner (chromosome territory); however, their internal structures are poorly defined. In particular, little is understood about the molecular mechanisms that govern the internal organization of interphase chromosomes. The author recently proposed that pairing (or interaction) of repetitive DNA-containing chromatin regions is a critical driving force that specifies the higher-order organization of eukaryotic chromosomes. Guided by this theoretical framework and published experimental data on the structure of interphase chromosomes and the spatial distribution of repetitive DNA in interphase nuclei, I postulate here a molecular structure of chromatin organization in interphase chromosomes. According to this model, an interphase chromosome is a chromatin mesh (or lattice) that is formed by repeat pairing (RP). The mesh consists of two types of structural components: chromosome nodes and loose chromatin fibers. Chromosome nodes are DNA repeat assemblies (RAs) that are formed via RP, while loose fibers include chromatin loops that radiate from the nodes. Different loops crosslink by RPs and form a large integrated chromatin network. I suggest that the organization of the chromatin network of a given interphase chromosome is intrinsically specified by the distribution of repetitive DNA elements on the linear chromatin. The stability of the organization is governed by the collection of RA-formed nodes, and the dynamics of the organization is driven by the assembling and disassembling of the nodes.
Chromatin Organization by Repetitive Elements (CORE): A Genomic Principle for the Higher-Order Structure of Chromosomes
Shao-Jun Tang
Genes , 2011, DOI: 10.3390/genes2030502
Abstract: Eukaryotic genomes contain a large amount of DNA repeats (also known as repetitive DNA, repetitive elements, and repetitive sequences). Here, I propose a role of repetitive DNA in the formation of higher-order structures of chromosomes. The central idea of this theory is that chromatin regions with repetitive sequences pair with regions harboring homologous repeats and that such somatic repeat pairing (RP) assembles repetitive DNA chromatin into compact chromosomal domains that specify chromatin folding in a site-directed manner. According to this theory, DNA repeats are not randomly distributed in the genome. Instead, they form a core framework that coordinates the architecture of chromosomes. In contrast to the viewpoint that DNA repeats are genomic ‘junk’, this theory advocates that repetitive sequences are chromatin organizer modules that determine chromatin-chromatin contact points within chromosomes. This novel concept, if correct, would suggest that DNA repeats in the linear genome encode a blueprint for higher-order chromosomal organization.
Succession and innovation of Chinese traditional surgery: a perspective on the history
TANG Han-Jun
Zhong Xi Yi Jie He Xue Bao , 2005,
Abstract: Facing the challenge of modern medicine, how to develop Chinese traditional surgery is a question. The tremendous heritage of traditional Chinese medicine (TCM) is the springhead of the development and innovation of TCM. Succession and innovation is an eternal subject for the development of Chinese traditional surgery. In order to improve Chinese traditional surgery, we should explore traditional medical literature, and carry forward the theories of Chinese traditional surgery
Non-combining Incremental Relaying Protocol for Amplify-and-forward Cooperative Systems
Tang Jun,Wang Liejun
Information Technology Journal , 2013,
Abstract: In this study, a two-hop amplify-and-forward cooperative system is considered. By exploiting the limited feedback from the destination, this study has proposed a Non-combining Incremental Relaying (NCIR) protocol. The asymptotic behavior of the symbol error probability is analyzed and its spectral efficiency issue is addressed. The study also utilizes the relay selection technique to further improve the system performance. Simulation results demonstrate that the proposed scheme outperforms the conventional alternatives in terms of both error performance and bandwidth efficiency.

Looking into “Peasantry Worker Shortage” from Two Points of View of Economy and Law
Jun-fang TANG
Cross-Cultural Communication , 2005, DOI: 10.3968/1730
Abstract: Chinese labour policy and law should be blamed. Conformism, lockstep and bureaucratism of labour management model of the management departments , discuss principles of labour law research make labour problems more serious, peasantry worker shortage is the model. This treatise analyses the reasons of peasantry worker shortage cosmically breaking out in some economy upgrowth areas in 2003-2004. The inner reason relates to ecomomy, mainly is long-term distortion of peasantry worker’s laborage; the external reason is faultiness of Labor Law and Legal Aid Law; and the influence of nation’s macroscopical regulation and controlling. This treatise abandon academic airs and graces of law research , taking the spirit of being practical and realistic in science research, impersonally analyzes the cause of formation and relative legal problems. Key words: peasantry worker shortage, duality labour force market, Romer Model and Lucas Model, Labor Law, Legal Aid Law Résumé: Avec le développement profond de la mondialisation économique , la connotation de la gestion du personnel envoyé à l’étranger dans les sociétés transnationales a beaucoup évolué depuis ces 5 dernières années . Depuis longtemps , la recherche de la gestion du personnel envoyé à l’étranger s’est concentrée principalement sur le micro-aspect individuel des employés envoyés aux pays développés , telle que l’adaptabilité interculturelle des individus , alors que l’on s’intéresse beaucoup moins à la gestion du personnel envoyé dans les pays en voie de développement , ce qui est insuffisant pour notre connaissance des traits de la gestion et de la tendance du développement du personnel envoyé à l’étranger dans les sociétés transnationales . Basé sur les données révélées dans les 11 enquêtes et les recherhes représentatives sur le personnel envoyé à l’étranger à partir de l’an 2000 , ce texte expose pour la première fois la question de la différence de la gestion du personnel envoyé à l’étranger et fait un bilan brèf sur la tendance d’évolution de la gestion du personnel envoyé à l’étranger dans les entreprises transnationales qui se siègent en Chine sous sept aspects suivants : 1 , évolution de catégorie des pays 2 , évolution quantitative du personnel 3, évolution de poste du personnel envoyé à l’étranger 4, évolution de temps 5 , évolution de modèle 6 , évolution de formation du personnel envoyé à l’étranger 7 , pluralisme du rénumération du travail du personnel envoyé à l’étranger . mots-clés: personnel envoyé à l’étranger, gestion interculturelle, gestion des ressources humaines, tendance du développe
