THE idea of a dual analysis in finite elements of a given structure was put forward in Ref. 4. The first analysis should be of the displacement type, using conforming displacement models of the finite elements. This results in a continuous, piecewise differcntiable displacement field in the whole structure, for which linear elasticity theory predicts lower bounds to the local static influence coefficients. The second analysis should be based on equilibrium models of the finite elements. The stress field within the structure is then continuously transmitted across the interfaces and satisfies detailed equilibrium conditions in the interior of each element. This property furnishes upper bounds to the influence coefficients.

This paper aims to theoretically and numerically investigate the steady two-dimensional (2D) Hiemenz flow with heat transfer of Reiner-Rivlin fluid over a linearly stretching/shrinking sheet.

The Navier–Stokes equations are transformed into self-similar equations using appropriate similarity transformations and then solved numerically by using shooting technique. A simple but effective mathematical analysis has been used to prove the existence of a solution for stretching case (λ> 0). Moreover, an attempt has been laid to carry the asymptotic solution behavior for large stretching. The obtained asymptotic solutions are compared with direct numerical solutions, and the comparison is quite remarkable.

It is observed that the self-similar equations exhibit dual solutions within the range [λ_c, −1] of shrinking parameter λ, where λ_c is the turning point from where the dual solutions bifurcate. Unique solution is found for all stretching case (λ > 0). It is noticed that the effects of cross-viscous parameter L and shrinking parameter λ on velocity and thermal fields show opposite character in the dual solution branches. Thus, a linear temporal stability analysis is performed to determine the basic feasible solution. The stability analysis is based on the sign of the smallest eigenvalue, where positive or negative sign leading to a stable or unstable solution. The stability analysis reveals that the first solution is stable that describes the main flow. Increase in cross-viscous parameter L resulting in a significant increment in skin friction coefficient, local Nusselt number and dual solutions domain.

This work’s originality is to examine the combined effects of cross-viscous parameter and stretching/shrinking parameter on skin friction coefficient, local Nusselt number, velocity and temperature profiles of Hiemenz flow over a stretching/shrinking sheet. Although many studies on viscous fluid and nanofluid have been investigated in this field, there are still limited discoveries on non-Newtonian fluids. The obtained results can be used as a benchmark for future studies of higher-grade non-Newtonian flows with several physical aspects. All the generated results are claimed to be novel and have not been published elsewhere.

This paper aims to find out the factors that influence the choice of dual innovation strategies in the process of knowledge pricing and transaction between first-mover and late-mover companies in an open innovation environment and also to find the key factors that affect the company's strategic choice in factors such as heterogeneous market environment, demand elasticity, exploration risk intellectual property prices and transaction cost.

This study uses the Cournot equilibrium and Stackelberg two-stage master-slave game model to describe the evolutionary process of knowledge pricing in an open innovation environment of first-mover and late-mover companies.

Research shows that in an open innovation environment, the formation of a dual innovation strategy in the pricing process of corporate intellectual property transactions is a complex process. Changes in one-time transaction costs and changes in the inverse demand coefficient of the innovation market play the decisive role in the choice of dual innovation strategies. When the demand of the innovation market is moderate, the inverse demand coefficient of the innovation market and the one-time transaction cost has an inverted U-shaped influence relationship. As the innovation market's inverse demand coefficient and the one-time transaction cost increase at the same time, the degree of differentiation of the enterprise's dual innovation strategy choice gradually reduces; when the one-time transaction cost is the largest, the degree of strategy differentiation is minimized.

Based on the above relationship, suggestions are made to guide enterprises in the knowledge pricing and transaction process in an open innovation environment, promote enterprises to form a dislocation development and complementary advantages in the knowledge innovation ecological chain and improve the overall innovation efficiency of the industry.

Transformational leadership (TFL) has been identified by a number of studies as a positive force for business success. However, few studies have explicitly examined its influence on the cooperative employment relationship, such as frontline employees' voice in the workplace. Thus, this study conducts an empirical analysis of dual-level (i.e. group-focused and individual-focused) TFL and its effect on frontline employees' cooperative voice.

This empirical study is based on data from a survey of 468 full-time frontline workers from 38 hotels in China.

The empirical results revealed that both individual-level and group-level TFL are significantly associated with frontline employees' cooperative voice. Person–Organization value congruence and Person–Supervisor value congruence both act as mediators in the linkage between group-level TFL and employees' cooperative voice behaviors. The partial mediating role of Demand–Ability congruence on the relationship between individual-level TFL and cooperative voice is also established.

First, this study investigates the dual-level effects of TFL on the cooperative voice behavior of frontline employees. Second, this study explores whether three dimensions of value congruence mediate the influence of TFL on the voice behaviors of employees.

The purpose of this paper is an attempt to design a proper incentive coordination mechanism to deal with the channel conflicts between the traditional sales and online direct sales.

With respect to the problems of channel conflicts between the traditional sales and online direct sales, to optimize the sale system and get more profits, considering the influences of consumer network acceptance, the authors establish demand and profit function based on consumer's utility, respectively. What's more, we exploit the game theory to analyze the optional decisions of the supply chain under the incentive coordination condition and no incentive coordination condition, and then we discuss the supply chain's optimal pricing, demand, profit and compensation incentive levels with the different effect of consumer network acceptance.

The level of compensation incentive provided by the manufacturer is influenced by consumer network acceptance and product cost. The lower the consumer network acceptance, the better the compensation incentive coordination effect of manufacturers. Manufacturers, wholesalers, retailers and consumers are all important players in real supply chain relationships. When a manufacturer exists as a dominant role, it should pay full attention to the impact of consumer behavior on supply chain decisions.

The research can clarify the influence and mechanism of consumer behavior on supply chain channel conflict coordination, and deal with channel conflicts.

The proposed incentive coordination can effectively realize supply chain channel conflict resolution, and provide decision-making ideas and methods for manufacturers to develop the supply chain management of online direct sales channels.

This paper proposes a novel hybrid simulation approach that incorporates the structural equation model (SEM) and system dynamics (SD) to investigate the impacts of leadership dynamics on project performance under different scenarios.

SEM is used to identify and validate a correlation between leadership variables and project performance statically. On this basis, the SD model is constructed to depict a system model connecting the leadership and project performance. Different scenarios are simulated to dynamically model the variation in leadership on the evolution of project performance.

Results indicate that (1) leadership can be divided into personal ability, relationship atmosphere and organizational strategy in complex construction projects; (2) personal ability, relationship atmosphere and organizational strategy positively correlate with project performance over time; and (3) L1 (stress management ability), L7 (team building) and L17 (institution support) are the leading factors influencing project performance and should be paid more attention under limited resources.

This research contributes to (1) the state of the knowledge by proposing a hybrid methodology that can systematically model the impacts of leadership dynamics on project performance over time and (2) the state of the practice by gaining a better understanding of the strategy of resource distribution for enhancing project performance in complex construction projects.

This research aims to study whether consumers differ in their attitudes toward equivalent prices that include vs exclude taxes and fees. In addition, this research will study whether computation ease-based processing fluency and perceived price fairness mediate this relationship in parallel, and whether need for cognition and political beliefs and affiliation moderate the effect.

Two experiments were conducted in which participants evaluated two price formats and then responded to relevant measures.

This research shows that consumers perceive prices that include (vs exclude) taxes and fees to be easier to process, and a fairer price, and subsequently exhibit a higher willingness to buy. Additionally, this effect is moderated by need for cognition, and political beliefs and affiliation.

Future research could investigate potential additional situational moderators (such as price type – total vs unit, consumption category, relative sizes of base price vs taxes and fees) and dispositional moderators (such as price sensitivity and tightwadism/spendthriftism).

This research provides insights to marketers regarding the downstream impact of pricing decisions – such as including vs excluding taxes and fees from total price. Further, depending on the product category and target customer characteristics (political affiliation), marketers can determine whether to include or exclude taxes and fees.

This research highlights the tendency of conservatives to avoid taxes and fees. As such, it adds to the understanding of conservative consumer groups.

This research contributes to existing research on price-framing research by finding an interesting effect related to multi-dimensional pricing and partitioned pricing. Additionally, this research contributes to existing research on computation ease-based processing fluency and price fairness perception. Finally, this contributes to an increasingly important body of research: the effect of political affiliation on consumption. This also provides clear guidance to marketers with regard to deciding service pricing.

The purpose of this paper is to emphasize the importance of the sources and means of communications that inform consumers about food risks. Another basic aim of this study is to identify certain effects of communication, such as a change, if any, in consumers' purchasing habits as a result of information they obtain.

Field research was carried out in urban areas of Van province, which is located in the eastern part of Turkey. Questionnaire surveys were conducted through face‐to‐face interviews with consumers. The sample size was 300 determined using sampling selection method. The data obtained were classified and interpreted according to the education level of the consumers. Chi‐square analyses were added to selected charts. In addition, correspondence analysis was used to analyze the general characteristics of consumers related to change in consumption habits and information level regarding the organizations, which supervise food enterprises.

Television was the main information source about food safety for all groups. It was found that consumers changed their food purchasing habits according to the information they received from various sources. However, unlike other groups, those with the lowest educational level mostly took information from health professionals. It was found that 85 percent of participants with a university‐level education changed their food purchasing behavior, compared with 56 percent of the participants in the lower educated consumer group. While 46 percent of participants preferred only food products with a quality guarantee, 29 percent of consumers stopped purchasing the food product and 18 percent of consumers began to pay greater attention to food labeling.

This study assessed changes in consumer attitudes towards the consumption of food products during the preceding 6 months after receiving information from various communication tools regarding food safety.

Establishing the validity and measurement equivalence of core marketing concepts in the emerging market economies of Africa is a key step in assessing the transferability of modern marketing theory and managerial practice to these countries. However, measurement equivalence issues are rarely addressed in studies of marketing practices in Africa. Accordingly, this study examines the equivalence of core marketing concepts based on interviews of 459 marketing managers from Kenya, Nigeria, Japan and the USA. The results show that optimal scaling analysis of the managers’ evaluations provide more valid and meaningful assessment than that of the raw data. The managers’ evaluations of the concepts revealed amazingly similar or prototypical perceptions of marketing’s core concepts and its applicability in their organizations, despite the profound country environmental differences. It appears that the concepts fall into two cross‐national categories of applicability that permeate the industrialized and developing country categorization. Managerial and research implications are discussed.
