This paper explores the contextual factors involved in the development and application of paradigmatic theories in general, and the application and development of Agency Theory in the Chinese context in particular.

Referring to four templates for the design of conceptual papers as outlined by Jaakkola (2020), i.e. theory synthesis, theory adaptation, typology and model – we adopt an approach combining theory/literature synthesis and model establishment. Based on a thorough analysis and discussion of the literature on the topics of “context effect “, “interface between theory and context”, “special characteristics of Chinese context” and “invalid application of Agency Theory in a Chinese context”, we use Agency Theory as the lens to discuss the importance of context in applying and developing paradigmatic theory specifically. We start from the contextualization of Agency Theory and then explore approaches to theorizing the Chinese context by developing a conflict coefficient model.

First, the application validity of paradigmatic theories is not sustainable; contextual factors are critical in applying and developing not only propositional but also paradigmatic theories, such as Agency Theory. Second, the Chinese context requires special attention when applying paradigmatic theories originating from Western countries. Third, the traditional application logic of Agency Theory is invalid in the Chinese context due to the coexistence of principal-agent conflicts (PAC) and principal–principal conflicts (PPC), and changeable dominance status of two conflicts according to the contexts. Based on these observations, a model of contextualization theory of PAC and PPC (i.e. conflict coefficient model) is developed from a dynamic perspective, which connects the separated situation states and allows the identification and measurement of the relative severity of the two types of agency conflicts.

Practitioners can also use this model to identify and measure the relative strength of the two conflicts and determine the direction of control and improvement. Moreover, analysis of Chinese context and agency problems of Chinese firms also has great practical significance considering the increased importance of the Chinese market and the increasingly important role played by Chinese firms in the international economy in general, and in specific host countries in particular.

First, in general, this study expands Whetten's (2009) study of the interface between theory and context. It specifically discusses approaches to considering contextual factors in the development and application of the relatively overlooked paradigmatic theories, using traditional and widely used Agency Theory as a lens. Our study suggests that typical Agency Theory, developed based on Western-centric assumptions, does not completely hold in the context of Chinese business practices because of different cultural, legal and governance realities. Second, it improves and extends the application of Agency Theory by proposing the new perspective that PAC and PPC coexist in specific contexts and positing that the relative severity of two types of agency conflicts depends on the context variables. Third, it puts forward a conflict coefficient model offering a more comprehensive, intuitive and quantifiable method for comparing the extent of the two conflicts in different scenarios, providing a reference for empirical studies of corporate governance.

With high-speed urbanization and strict requirements on energy conservation and environmental protection, eco-city has become the priority of urban development in China. Governments of all levels promote various eco-city planning schemes within a short term, but most schemes are characterized by randomness and subjectivity. To solve the lack of scientific pre-implementation evaluation for eco-city planning and improve eco-city construction quality, a systematic analysis is conducted in this study from three dimensions, namely, eco-city planning scheme, operating mechanism, and guarantee measures. A 3D evaluation model for eco-city planning is constructed through index selection. Schemes are ranked comprehensively with the distance measure method, and projection analysis is performed with the four-grid evaluation screen. Finally, the 3D evaluation model is applied to evaluate eco-city planning for Shenzhen, Chongqing, and Weifang. Results show that the model can be used to evaluate eco-city planning schemes effectively and comprehensively and offers targeted optimization suggestions in accordance with the evaluation results. Construction of the 3D evaluation model of eco-city planning based on the distance measure to determine the reasonability of eco-city planning reduces the institutional and social costs of eco-city planning practices.

This paper aims to examine the internal logical relationship between two intergenerational inheritance ways of passing property rights and residual control rights (RCR) and to construct a conceptual model comprising transfer elements, paths and timing of succession in this process.

Driven by the cases of Haixin, Tianyijiao and Changhe Group, this paper applies research methods of copying and expanding analysis logic, progressive deduction, content analysis and comparative research based on the perspective of HeXie theory to explore the deep interrelation of transfer elements, paths and timing during family business succession.

The findings present that the content of intergenerational inheritance of a family firm is the inheritance of property rights and RCR. First, the inheritance of property rights is a static inheritance of time-point delivery, whereas the inheritance of RCR is a dynamic inheritance process for a period of time. Second, the inheritance of property rights and RCR are not independent; only a “HeXie” succession of both rights can realize a successful inheritance of family firms.

This paper constructs the paths and timing model of intergenerational inheritance of property rights and RCR in family firms. This paper integrates the current literature studies on the family inheritance of property rights and RCR and explains their internal mechanisms. This paper also provides a theoretical foundation and empirical evidence for family business transitions in the business world.

This paper aims to investigate the fretting wear mechanism of an Al-Li alloy at room temperature, the tangential fretting wear tests were carried out.

The effects of displacement amplitude and fretting frequency on the tangential fretting wear characteristics were mainly investigated. The experimental data obtained are analyzed and compared.

The results indicated that the fretting friction coefficient increased with the increase of displacement amplitude. As the displacement amplitude increased, the wear scar morphology changed significantly, mainly in terms of delamination debris and furrow scratches. The wear mechanism changed from initial mild wear to more severe oxidative wear, adhesive wear and abrasive wear.

This paper extends the knowledge into mechanical tight connections. The conclusions can provide theoretical guidance for the fretting of mechanical tight connections in the field of automotive lightweight and aerospace.

The purpose of this paper is to estimate the elasticities of demand for different dairy products, such as fresh milk, powdered milk and yoghourt, in urban China.

The household survey data are drawn from the annual Urban Household Survey in a Chinese province from 2007 to 2009 by applying a three-stage budgeting approach with zero consumption.

The major findings show that fluid milk is the most popular dairy product among urban households in Guangdong province, China. Demand for fresh milk is price elastic with the highest value being −1.043, indicating that price-cutting promotion programs could be carried out by dairy enterprises to increase dairy consumption. With improvements in the living standards, the demand for dairy will lead to an expansion in the size of the dairy market and will simultaneously open up new development opportunities for dairy enterprises.

This study adopts an Almost Ideal Demand System model inserted into inverse Mills ratios in the third stage to resolve the common problem of obtaining censored data on zero consumption observations. The research findings will provide a reference for policy makers and for enterprises in developing some price-cutting promotion programs.

Sargassum fusiforme is a popular edible seaweed in coastal cities of China that contains diverse nutrients including iodine. Cooking is an effective way to improve food safety, but it can alter both the contents of elements along with speciation and bioavailability. Three common cooking methods, the soaking, steaming and boiling, were evaluated for their effects on the protein structures, protein digestibility, iodine content and iodine bioavailability of S. fusiforme.

Fourier transform infrared spectroscopy was used to study the structural changes of protein, and an in vitro digestion/Caco-2 cell culture system was used to evaluate the digestibility of protein, bioaccessibility and bioavailability of iodine.

Boiling and steaming altered the protein secondary structure demonstrated by increased a-helix and random coil and decreased β-sheet, which improved the in vitro protein digestibility. Iodine content was reduced by cooking, with the highest loss observed after boiling, followed by soaking and steaming, while it was found that both bioaccessibility and cellular uptake of iodine were significantly elevated by boiling and steaming using an in vitro digestion/Caco-2 cell culture system. The presence of ascorbic acid, citric acid or tyrosine was beneficial for the iodine absorption, while oxalic acid and phytic acid hindered the iodine bioavailability.

The present finding suggested that cooking was conducive to the digestion and absorption of iodine in S. fusiforme. In addition, different dietary factors could have a certain impact on the absorption of iodine. Results of the study are essential for improving the application value of S. fusiforme to ensure reasonable consumption of seaweeds.

This paper aims to investigate the informativeness of rhetorical impression management patterns of CEO letters and examines whether these rhetorical features affect financial analysts’ forecasting behaviour.

The authors use textual analysis on a sample of 526 CEO letters of US firms and apply factor analysis on individual linguistic style measures to identify co-occurrence patterns of style features.

The authors identify three holistic style patterns (assertive acclaiming, cautious plausibility-based framing and logic-based rationalizing) and find that assertive rhetorical feature in CEO letters is negatively related with the dispersion of financial analysts’ earnings forecasts and positively associated with earnings forecast accuracy. CEOs’ use of a rationalizing rhetorical pattern tends to decrease the dispersion of financial analysts’ earnings, whereas a cautious plausibility-based rhetorical position is only marginally instrumental in getting more accurate earnings predictions.

Whilst impression management communication is often theorized as manipulative and void of real information content, the findings suggest that impression management serves both self-presentation and information-sharing purposes.

This paper elaborates on the co-occurrence of style characteristics in management communication and is a first attempt to validate the external ramifications of holistic style profiles of corporate narratives by focusing on an economic target audience.

Using composite style measures of the letter to shareholders, the purpose of this paper is to elaborate dominant rhetorical profiles and qualify them from an impression management (IM) perspective. In addition, the paper examines how institutional differences affect rhetorical profiles by comparing intensity and contingencies of rhetorical profiles of UK and US companies.

The authors use automated text analysis to capture linguistic style characteristics of a panel of UK and US companies and employ factor analysis to determine rhetorical profiles. Next, the authors investigate company-level and country-level determinants of a company’s rhetorical stance.

The authors document three prominent rhetorical profiles: an emphatic acclaiming stance, a cautious plausibility-based framing position, and a logic-based rationalizing orientation. The profiles represent distinct self-presentational logics and have different readability effects. Rhetorical IM is stronger in US companies, but higher expected scrutiny in the US institutional environment affects sensitivity of rhetorical postures to message credibility and litigation risk, while marginally increasing the less litigation-sensitive defensive framing style in US letters.

The authors develop replicable archival-based measures of prominent rhetorical IM traits of the shareholder letter, based on composite style features. The authors argue that they are qualitatively different from content-based IM proxies. The authors investigate their institutional and organizational relevance by examining how company features and country-level differences affect incentives and constraints for style-based rhetorical IM.

Flow force is one of the crucial factors affecting the performance of conical throttle valves. The purpose of this paper is to determine the relationship between the flow force and operating parameters of the conical throttle valve.

The flow force of the throttle valve can be obtained by the difference between the axial force and static pressure on the valve spool. In this paper, the internal fluid is divided into two regions and the axial force and static pressure are obtained, respectively. In addition, a two-dimensional axisymmetric simulation model and experimental test are carried out to validate the results of the flow force.

It can be seen that the theoretical, simulation and experimental results exhibit high agreement with each other and the error between them decreases with the increase in the size of the opening. The curves of pressure distribution reveal that the pressure on the spool first decreases then increases when it reaches the minimum pressure at the orifice. Additionally, the minimum pressure decreases with the increase of opening and pressure difference. The results also indicate that the increase in the size of the opening and inlet pressure has a positive effect on the flow force. However, the increase in outlet pressure has a negative effect on the flow force.

In this paper, the flow force calculation model of conical throttle valve is established and the influence of operating parameters on the flow force of conical throttle valve is studied.

In the context of exploring and implementing China's new urbanization, green eco-city have become a transformation model for urban development. Sharpening green buildings in the construction industry can significantly influence and determine China's economic growth trends, as well as the growth and overall development of its national economy. However, current green eco-city still lack appropriate standards and scientific theoretical basis to determine the target star program of green buildings. To fully implement the green building standards, establish and improve a sound technical standard system for the construction of green building demonstration areas, this study considers the spatial layout of green buildings as the core, adopts a plot potential evaluation method for evaluating a few green building plots, and utilizes four factors in verifying plots with great star potential. The study also establishes a system to calculate the star proportion of green buildings and applies the system in calculating the green building ratio of GM New District. Results indicate that the system can quantitatively analyze a plot potential, calculate the star proportion of green buildings scientifically and rationally, and provide some references for the construction of eco-city and the preparation of special planning for green buildings. The system construction is conducive to provide technical support for the construction of green eco-city. The improved system can be applied in the green building demonstration areas in China, and will be a reference model of constructing green building demonstration areas in the country.
