Instead of studying the impact of media on society,the traditional"top down"orientation of most communication studies scholars,this keynote presentation adopted the opposite perspective,exploring the"bottom-up"impact of"society"on"media".Unlike conventional"agenda-setting theory",which suggests that nationally prominent news media set issue"agendas"for other news media and public opinion,and also unlike the"guard dog"view that media essentially protect the interests of political and economic elites,the"community structure theory"explores links between different community(typically city or nation-state)demographics and variations in reporting on critical health concerns.Summarizing his scholarship on health communication presented and published over decades,the speaker outlined community structure theory's illumination of two overall patterns in US and cross-national coverage of health communication issues.In US coverage,broad measures of economically"buffered"privilege(educational,income,or occupational advantage)are linked to"favorable"or"government responsibility"coverage of health issues,and specific measures of"health"privilege(physicians,hospitals)are connected to"favorable"or"government responsibility"coverage promoting selected health issues.In cross-national coverage,specific measures of national"health vulnerability"(such as percent without improved water access,infant mortality rate)are linked to"government"responsibility coverage for selected health issues(human trafficking,water handling/contamination).In addition,broad measures of"macro"vulnerability conditions(agricultural dependence,political instability)are associated with"government"responsibility coverage for a wide range of health issues(genetically modified foods,drug trafficking,condom promotion,and food security).Overall,community structure theory's"bottom up"perspective reveals how the vulnerable are empowered by their demographic alignment with variations in health communication. 展开更多

Based on behavior science and direct causes analysis of serious accidents in Chinese coal mines in recent 5 years, a conclusion that unsafe behaviors of coal mine staff were the direct causes of these serious accidents was drawn, accounting for 91.3%. If staff was divided into executor and manager, percentages of the executor's and manager's unsafe behaviors in direct causes of the accidents were 69% and 54%, respectively, with executor's unsafe behavior as direct causes and manager's unsafe behavior as essential reasons after thorough analysis of these accidents. Further, on the basis of dual structure theory analysis, three new understandings, including transformation, hierarchy classification and representativeness of behavior factors were il- lustrated. Behavior factors of executors and managers in Chinese coal mines were summarized and classified by new recogni- tion. Then, dual structure theory was applied in a coal mine in Hebei Province of China; weakening unsafe behaviors and strengthening safe factors can attain the purpose of motivating safer behaviors in the coal mine. 展开更多

Enterprise capital structure means the various resources, combination and relationships of enterprise raising capital as well as means the short or long debts, shareholders' rights and interest, and the proportional relationships among constituting items. Capitals raised by enterprise from different ways constitute the capital sum. Because of changing enterprise operation, the capital structure is also various and it cannot be in a fixed proportion. Therefore, we need to optimize the capital structure of state-owned enterprises so as to reach the rational resources allocation and make the national economy develop soundly and rapidly. How to optimize it? This is a big problem that we have to face. Debt-to-equity swap at the moment is only the transition for correcting capital structure of state-owned enterprises. Decreasing stocks owned by state is the inevitable choice for optimizing enterprise stock right. 展开更多

The geometries, stabilities, and electronic properties of FSin (n=1~12) clusters are systematically investigated by using first-principles calculations based on the hybrid density-functional theory at the B3LYP/6-311G level. The geometries are found to undergo a structural change from two-dimensional to three-dimensional structure when the cluster size n equals 3. On the basis of the obtained lowest-energy geometries, the size dependencies of cluster properties, such as averaged binding energy, fragmentation energy, second-order energy difference, HOMO–LUMO (highest occupied molecular orbital–lowest unoccupied molecular orbital) gap and chemical hardness, are discussed. In addition, natural population analysis indicates that the F atom in the most stable FSin cluster is recorded as being negative and the charges always transfer from Si atoms to the F atom in the FSin clusters. 展开更多

By studying the relationship between physical structure and function in physical chemistry, the author breaks through the limitation of the western narrow social and cultural structure and function theory, and further derives and founds the Confucian cultural structure and function theory, thus creating a new research methodology and broadening the research horizon. Through the research, it is found that the Confucian culture structure consists of the hard structure "ritual" and the soft structure "benevolence", and based on this constructs three-outline, five- principal, four-moral, eight- virtul, five cardinal principals and other Confucian culture, so that these have a social management function, resulting in a 2000-year stable Chinese social order, which also provides reference for the social management of Chinese government today. 展开更多

Aggression is required for survival and sex for propagation of species. Aggressive and sexual drive derivatives with their corresponding defence mechanisms are combined with biologically based stages of infant/child development and the functional entity of Structural Theory. This model of human nature is the applied to the diagnostic categories of DSM-5-TR. Objectives: To follow the innate Dual Instinct Theory from life to death and through Artificial Intelligence;connect it with biological stages of development of the Structural Theory and illustrate its manifestations in DSM-5-TR classifications. Method: Review of selected published literature. Applying the principle of focus and cognition of informed clinical observation of innate drive derivatives in conjunction with The Structural Theory. Both theories are functional entities with no structures involved. Sigmund Freud’s biologically based stages of development;oral, anal, genital pubic, adult, and geriatric along with a variety of unconscious, automatic, and persistent defense mechanisms are selectively folded into diagnosis listed in the manual. 展开更多

The structure and magnetic properties of Osn (n=11~22) clusters are systematically studied by using density functional theory (DFT). For each size, the average binding energy per atom, the second-order differences of total energies and the highest occupied molecular orbital (HOMO)–the lowest unoccupied molecular orbital (LUMO) gaps are calculated to analyze the stability of the cluster. The structures of Os14 and Os18 clusters are based on a close-packed hexagonal structure, and they have maximum stabilities, so n=14, 18 are the magic numbers. The 5d electrons play a dominant role in the chemical reaction of Osn clusters. The magnetic moments of Osn clusters are quenched around n=12, and when n=18~22 the value approximates to zero, due to the difference of electron transfer. 展开更多

The atomic geometry, structure stability, electronic and magnetic properties of VSe2 were systematically investigated based on the density functional theory(DFT). Varying from 3D to 2D four VSe2 structures, bulk 2H-VSe2 and 1T-VSe2, monolayer H-VSe2 and T-VSe2 are all demonstrated as thermodynamically stable by lattice dynamic calculations. More interestingly, the phase transition temperature is dramatically different due to the lattice size. Finally, owing to different crystal structures, H-VSe2 is semimetallic whereas T-VSe2 is totally metallic and also they have different magnetic moments. Our main argument is that being exfoliated from bulk to monolayer, 2H-VSe2 transforms to T-VSe2, accompanied by both semimetallic-metallic transition and dramatic magnetic moment variation. Our calculations provide a novel structure phase transition and an efficient way to modulate the electronic structure and magnetic moment of layered VSe2, which suggests potential applications as high-performance functional nanomaterial. 展开更多

An integration of organization culture in the conceptualization and development of Enterprise Resource Planning Systems (ERPs) is critical for an organization to reap potential benefits of the system. In this paper, the authors present an analytical approach through the Structuration Theory: How a university can assess its culture for the purposes of design and development of the ERPs. The authors extend the Structuration Theory by integrating it with the Activity Theory to provide the means of evaluating the activities that the system is to perform. The modified Orlikowski model is applied to depict the relationship between institutional properties, human agents, and technology in the university setup and how this offers a more inclusive approach to ERP systems development and implementation. 展开更多

This paper investigates the effectiveness of various factors upon the capital structure decisions of Chinese firms by conducting an empirical analysis of Chinese-listed retail companies.An unbalanced panel dataset was formed with a sample of 110 companies observed for 12 years(2010~2021).Each observation is measured quarterly.Traditional explanatory variables are adopted in the study,including profitability,company size,tangibility of assets,internal financing ability,tax ratio,growth opportunities,and volatility.By employing the Fama-Macbeth approach,the regression results are interpreted to determine the impact of independent variables upon the leverage a company takes on.To solve the reverse causality problem,we include the lag term(last quarter’s data)of the debt-to-equity ratio as control variables.Consistent with previous theoretical and empirical studies,firms’leverage ratio is positively related to size,tangibility,tax ratio,and last quarter’s debt level.Companies’profitability and internal financing ability are negatively correlated with their debt-to-equity ratio.Firms’earning volatility and growth opportunities do not show significant relationship with the debt-to-equity ratio.The study has provided more empirical evidence on capital structure theories regarding emerging financial markets. 展开更多

Raman spectra of the oligopeptide chains are examined. The geometric structures, frontier orbital, energy gap, atomic charge distribution, density of states and chemical activity of the side chain are studied at the B3LYP/6-31G(d) level. Results show that, with the number of residues increasing, vibrations of typical functional groups present Raman frequency shift, and the energy gap is gradually reduced. The HOMO and LUMO focus on the amino and carboxyl at the ends of oligopeptides. It is helpful for oligopeptides to self-assemble into chains. In addition, different residues(glycine or alanine) at the ends of chains result in the even-odd effect of orbital energy in the growth process. The size effects of physical and chemical properties only exist when the oligopeptides are shorter, and the phenomenon disappeared as the chain continues to grow. 展开更多
