Following Hovland’s persuasion theory, this paper aims to develop a conceptual model and analyzes characteristics of online political deliberation behavior from three aspects (i.e. information, situation and manager). Based on the whole interactive process of online political deliberation, this paper aims to reveal the key points that affect the response effect of the government from the persuasive perspective of online political consultation.

Based on more than 40,000 netizens’ posts and government responses from 2011 to the first half of 2019 of the Chinese political platform, this paper used the text analysis and machine learning methods to extract measurement variables of online political deliberation characteristics and the econometrics analysis method to conduct empirical research.

The results showed that the textual information, political environment and identity of the political objects affect the effectiveness of government response. Furthermore, for different position categories of political officials, the length of political texts, topic categories and emotional tendencies have different effects on the response effectiveness. Additionally, the effect of political time on the effectiveness of response differs.

The findings will help ascertain the characteristics of online political deliberation behavior that affect how effective government response is and provide a theoretical basis for why the public should express their political concerns.

This paper aims to analyze the corrosion and corrosion inhibition of N80 in 10 per cent HCl + 8 per cent fluoroboric acid (HBF₄) solution for acidizing operation.

The corrosion rate, kinetic parameters (Ea, A) and thermodynamic parameters (ΔH, ΔS) of N80 steel in fresh acid and spent acid, 10 per cent HCl + 8 per cent HBF₄, 10 per cent HCl and 8 per cent HBF₄ solutions were calculated through immersion tests. The corrosion and inhibition properties were studied through X-ray diffraction and electrochemical measurements. The corrosion morphology of the corrosion product was examined by scanning electron microscopy (SEM).

The results demonstrated that the spent acid was the main cause of acidification corrosion, and the HBF₄ would cause serious corrosion to N80 steel. The results showed that the N80 steel was more seriously corroded in the spent acid than in fresh acid, and the hydrolysis of HBF₄ accelerates the dissolution process of N80 steel anode to control the corrosion reaction. The results showed that the acidification will definitely cause serious corrosion to the oil tube; therefore, necessary anti-corrosion measures must be taken in the acidification process.

The results showed that acidizing the formation with 10 per cent HCl + 8 per cent HBF₄ will definitely cause serious corrosion to the oil tube, especially when the spent acid flows back. Therefore, necessary anti-corrosion measures must be taken in the acidification process, especially in the spent acid flowback stage.

The purpose of this paper is to examine Chinese police officers’ general support for police intervention into domestic violence, emphasizing adequate protection of the victims, and specific support for utilizing arrests to deal with the offenders.

This study relies on survey data collected from 1,064 police officers who worked in multiple areas in two provinces of China between June and July of 2019. OLS models were used to test whether organizational variables are significant predictors of officer attitudes toward domestic violence intervention.

Both agency endorsement and supervisory support are positively related to officers’ favorable attitudes toward police intervention into domestic violence and using arrests to handle offenders. The amount of training received from the agency on the recently promulgated Anti-Domestic Violence Law, however, has a negative influence on officer support for general intervention into domestic violence and no influence on officer attitudes toward arrests.

This study represents one of the first attempts to investigate the connections between organizational and managerial factors and Chinese officers’ support for both general and specific interventions into domestic violence. It contributes to the current literature that only included police cadets in the analysis of Chinese police attitudes toward domestic violence despite the fundamental differences between cadets and active-duty officers.

This study aims to assess the direct relationships between internal support and job satisfaction and voluntary assistance and their indirect connections through work–family conflict among Nigerian police officers.

Survey data were collected from police officers in a midsized state police command in Ebonyi state in Nigeria. Structural equation modeling (SEM) was used to assess the connections between supervisor support, peer support, work–family conflict, job satisfaction and voluntary assistance.

Police officers with stronger supervisor and co-worker support are more inclined to express higher job satisfaction, whereas such support is not linked to officers' willingness to help fellow officers. Work–family conflict mediates the relationship between co-worker support and voluntary assistance. Stronger peer support is accompanied by higher work–family conflict, which then is linked to greater helping behavior.

Despite many studies on police job satisfaction, research on correlates of job satisfaction in an African context remains severely under-investigated. This study represents one of the first attempts to assess police proactive helping behavior and job satisfaction in Nigeria.

The purpose of this paper is to develop a trading and pricing method of expansion option (EO) model to solve expansion problems of build-operate-transfer (BOT) freeway project.

This paper proposes an ex ante mechanism through trading the EO to avoid the transaction costs. By editing the paths generated from binomial option pricing model, this paper establishes an American real option binomial lattice model and evaluates the value of EO. Data are collected from Liaoning province in China and the model is practiced in the context of a BOT freeway in Liaoning province.

Supported by empirical evidence, this study finds out that there exists a minimum price at which the government can sell the EO and a maximum price that the private sector is willing to pay. When the minimum price is negative, the government should transfer the EO to the private sector free of charge to avoid the transaction costs. Otherwise, the government should sell the EO at a reasonable price to protect public interests.

The study can be used for the government to reducing the transaction costs. By using the trading EO model, the government can sell its share of the EO to the private sector to manage its resources efficiently.

This paper builds a trading EO model to solve expansion problems instead of renegotiations. In addition to reducing the transaction costs for the whole society, trading EO can also raise the respective payoffs of both public and private sectors. An EO trading framework and algorithm is further developed. It realized an American option model, making the owner can exercise the option whenever he wants. Thus, the whole model is adapted to best fit BOT highway practice.

The purpose of this paper is to discuss whether, in entrepreneurship disciplines, professors address equally the positive and negative aspects associated with being an entrepreneur. The literature shows that entrepreneurship professors are enthusiastic about entrepreneurial action, and there may be a bias toward predominant emphasis on positive aspects.

The case study strategy was used to analyze disciplines that qualify entrepreneurship professors. The content analysis technique was applied to the description of the discipline contents and texts from the most frequently used literatures. The selected case (the country) satisfied the condition of having a regulatory agency that evaluates courses and also provides descriptive records of the disciplines that are taught.

It was observed that the topics discussed in the disciplines, as well as the texts of the most frequently used articles, contain a higher volume of messages that are positive and favorable toward the entrepreneurial act. Negative effects or aspects of entrepreneurship are addressed superficially.

This article provides important reflections on the activities of those who teach entrepreneurship, as well as editors and reviewers of entrepreneurship journals. Regarding the former, when preparing the content of their disciplines, and for the latter, when evaluating articles, bearing in mind that their articles are also used by students and professors from countries with less developed economies.

Exploring the myths of entrepreneurship, especially the claim that everyone is capable of becoming an entrepreneur and that entrepreneurship promotes economic development, the risk of becoming an entrepreneur was addressed, especially in countries with less developed economies. From this viewpoint, issues regarding the responsible teaching of entrepreneurship were addressed, along with the need to focus equally on the favorable and unfavorable aspects of entrepreneurship.

City investment companies (CICs) in China, set up and funded by the government, are playing an important role in the construction of urban infrastructure in China. The purpose of this paper is to analyze the structural risk of diversified project financing of CICs and explore its key influencing factors.

The best worst method (BWM) is used in this study to empirically analyze and quantitatively study the optimization of the structural risk of diversified financing of CICs.

In this study, the structural risk of diversified financing of CICs has been clearly defined, and its key evaluation indexes, including the structure of projects, the structure of financing, asset-liability ratio, earnings before interest and tax margin, the rate of return on capital and the ratio of long-term debt and short-term debt, have been determined. What is more, a comprehensive evaluation system of the structural risk of diversified financing has been established.

This study has established a comprehensive evaluation system of the structural risk of diversified financing. Based on the validated systematic evaluation, comparison and ranking of the structural risk of diversified financing of CICs by using the BWM, the ranking results can help investors to select the CICs with small structural risk of diversified financing to invest.

Various factors may influence project finance when a multi-sourced debt financing strategy is used for financing capital investments, in general, and public infrastructure investments, in particular. Traditional indicators lack comprehensive consideration of the influences of many internal and external factors, such as investment structure, financing mode and credit guarantee structure, which exist in the financing decision making of BOT projects. An effective approach is, thus, desired. The paper aims to discuss these issues.

This paper develops a financial model that uses an interval number to represent the uncertain factors and, subsequently, conducts a standardization of the interval number. Decision makers determine the weight of each objective through the analytic hierarchy process. Through the optimization procedure, project investors and sponsors are provided with a strategy regarding the optimal amount of debt to be raised and the insight on the risk level based on the net present value, as well as the probability of bankruptcy for each different period of debt service.

By using an example infrastructure project in China and based on the comprehensive evaluation, comparison and ranking of the capital structures of urban public infrastructure projects using the interval number method, the final ranking can help investors to choose the optimal capital structure for investment. The calculation using the interval number method shows that X2 is the optimal capital structure plan for the BOT project of the first stage of Tianjin Binhai Rail Transit Z4 line. Therefore, investors should give priority to selecting a capital contribution ratio of 45 per cent for this investment.

In this paper, some parameters, such as depreciation life, construction period and concession period, are assumed to be deterministic parameters, although the interval number model has been introduced to analyze the uncertainty indicators, such as total investment and passenger flow, of BOT rail transport projects. Therefore, more of the above deterministic parameters can be taken as uncertainty parameters in future research so that calculation results fit actual projects more closely.

This model can be used to make the optimal investment decision for a project by determining the impact of uncertainty factors on the profitability of the project in its lifecycle during the project financial feasibility analysis. Project sponsors can determine the optimal capital structure of a project through an analysis of the irregular fluctuation of the unpredictable factors in project construction such as construction investment, operating cost and passenger flow. The model can also be used to examine the effects of different capital investment ratios on indicators so that appropriate measures can be taken to reduce risks and maximize profit.

The purpose of this paper is to propose and test a conceptual model that explains racially/ethnically differential confidence in order institutions through a mediating mechanism of perception of discrimination.

This study relies on a nationally representative sample of 1,001 respondents and path analysis to test the relationships between race/ethnicity, multiple mediating factors, and confidence in order institutions.

Both African and Latino Americans reported significantly lower levels of confidence compared to White Americans. People who have stronger senses of being discriminated against, regardless of their races, have reduced confidence. A range of other cognitive/evaluative variables have promoted or inhibited people’s confidence in order institutions.

This study relies on cross-sectional data which preclude definite inferences regarding causal relationships among the variables. Some measures are limited due to constraint of data.

To lessen discrimination, both actual and perceived, officials from order institutions should act fairly and impartially, recognize citizen rights, and treat people with respect and dignity. In addition, comprehensive measures involving interventions throughout the entire criminal justice system to reduce racial inequalities should be in place.

Equal protection and application of the law by order institutions are imperative, so are social policies that aim to close the structural gaps among all races and ethnicities.

This paper takes an innovative effort of incorporating the currently dominant group position perspective and the injustice perspective into an integrated account of the process by which race and ethnicity affect the perception of discrimination, which, in turn, links to confidence in order institutions.

While there is a growing body of studies on the people's views of community policing, there have been a very few cross-national studies. The purpose of this paper is to compare and contrast students’ views on community policing from India and the USA.

The data were from a survey from a total of 434 Indian and 484 US college students.

Punitive orientation had a significant effect on attitudes toward community policing, but was related to an increase in the support in India and reduction of support in the USA. Among the Indian respondents, concern for crime and support for aggressive policing had positive associations with support for community policing, and police involvement in the community had a negative association. Among the US respondents, age, educational level, and perceptions of police effectiveness had positive associations with support for community policing, and holding a punitive orientation had a negative association.

This study represents the attempt to examine Indian perceptions of community policing empirically. Uncovering factors that affect public support for community policing can provide useful references for police administrators to develop policies and practices that encourage more active community involvement in crime control.
