The purpose of this paper is to increase our understanding of why firms, specifically small to medium‐sized enterprises (SMEs), participate in a programme for competence development and why firms use different strategies for competence development.

A study of 17 SMEs that all received support from the European Social Fund, Objective 3 programme. The collection of data is based on semi‐structured interviews with management/owners, internal project leaders, employees and union representatives, feedback seminars with representatives from the studied enterprises, and on analysis of documents.

The findings demonstrate that all SMEs reported driving forces for competence development relating to both external organizational conditions and internal organizational conditions, to at least a certain degree. Furthermore, there appears to be a strong relationship between observed patterns of driving forces and the strategy for competence development used by the firm.

The SMEs that experience a relatively stronger driving force for competence development initiate problem‐solving efforts to design and implement more elaborated strategies for competence development. The SMEs that experience a lesser degree of driving force for competence development implement less elaborated strategies for competence development.

The paper finds that both external and internal organizational conditions are important in understanding why SMEs undergo competence development programme. Furthermore, the importance of external and internal organizational conditions is not only limited to why the companies participate in a programme for competence development, but also for how they participate, i.e. the strategies used for competence development.

The purpose of this paper is to analyze the forces that prompted a Finnish food manufacturing company to implement environmental management system (EMS) and performance management system (PMS). The paper also aims to describe how and why environmental issues were integrated onto a balanced scorecard (BSC).

The paper utilizes both qualitative and longitudinal case study approaches. Semi‐structured interviews are the main source of empirical data; these were conducted by both researchers.

The forces driving the implementation of the EMS changed from external to internal forces over time. The initial purpose of EMS implementation was to obtain an environmental certificate. Later on the forces turned to internal ones when the causal link between improving environmental performance and profitability was recognized. The PMS implementation, as well as the PMS and EMS integration, had internal forces driving them. The company integrated environmental indicators into its BSC, which thus connected the EMS and PMS. This integration demonstrated the financial impacts of the environmental improvements.

The limitation relates to the methodological issues when the results can be generalized theoretically.

If dealing with environmental issues is considered to potentially increase profitability, there must be a great potential to improve environmental performance at the same time. If environmental measures are integrated into a BSC, they are monitored and discussed more precisely. The BSC is thus a worthwhile tool for reporting information on environmental performance. The construction of an EMS and a PMS requires a co‐operation between different functions and levels of the organization. Finally, the forces for improving EMS and PMS can emerge both from outside and inside.

This paper contributes to the empirical research on environmental and performance management by integrating these two issues, and also illustrates that forces are dynamic rather than static.

In the analysis of some near‐regular structures one can solve the regular part independently and then superimpose the effect of the additional part. For such models, the matrices corresponding to regular part have canonical forms and their eigensolution or inversion can easily be performed. The effect of member changing the regular to a near‐regular structure can then be added. The purpose of this paper is to analyze near‐regular structures using the force method.

The paper uses the force method, and instead of selecting a statically determinate basic structure (standard method), the paper employs the regular part of the structure as the basic structure.

A new algebraic method is introduced for the force method of analysis for efficient analysis of large near‐regular structures.

In this paper, the force method is used, however, instead of selecting a statically determinate basic structure, the regular part of the structure is employed as the basic structure. Those additional elements are considered as redundant elements. This method is applied to truss and frame structures. In the present approach it is possible to have missing elements instead of additional elements.

Under different ground motion excitation modes, the spatial coupling effect of seismic response for the arch bridge with thrust, seismic weak parts and the internal force components of the control section of main arch ribs are analyzed.

Taking a 490 m deck type railway steel truss arch bridge as the background, the dynamic calculation model of the whole bridge was established by SAP2000 software. The seismic response analyses under one-, two- and three-dimension (1D, 2D and 3D) uniform ground motion excitations were carried out.

For the steel truss arch bridge composed of multiple arch ribs, any single direction ground motion excitation will cause large axial force in the chord of arch rib. The axial force caused by transverse and vertical ground motion excitation in the chord of arch crown area is 1.4–3.6 times of the corresponding axial force under longitudinal seismic excitation. The in-plane bending moment caused by the lower chord at the vault is 4.2–5.5 times of the corresponding bending moment under the longitudinal seismic excitation. For the bottom chord of arch rib, the arch foot is the weak part of earthquake resistance, but for the upper chord of arch rib, the arch foot, arch crown and the intersection of column and upper chord can all be the potential earthquake-resistant weak parts. The normal stress of the bottom chord of the arch rib under multidimensional excitation is mainly caused by the axial force, but the normal stress of the upper chord of the arch rib is caused by the axial force, in-plane and out of plane bending moment.

The research provides specific suggestions for ground motion excitation mode and also provides reference information for the earthquake-resistant weak part and seismic design of long-span deck type railway steel truss arch bridges.

Posture adjustment plays an important role in spacecraft manufacturing. The traditional posture adjustment method, which has a large workload and is difficult to guarantee the quality of posture adjustment, cannot meet the requirements of modern spacecraft manufacturing. This paper aims to optimize the trajectory of posture adjustment, reduce the internal force of the posture adjustment mechanism and improve the accuracy of the system.

First, the measuring point is measured by a laser tracker and the position and posture of the cabin is solved. Then, Newton–Euler method is used to construct the dynamic model of the posture adjustment system (PAS) without internal force. Finally, the adjustment time is optimized based on Fibonacci search method and the trajectory of the cabin is fitted by the fifth order polynomial.

The simulation results show that, compared with the other trajectory planning methods, this method can effectively avoid the internal force of posture adjustment caused by redundant driving, and the trajectory of velocity and acceleration obtained are continuous, meeting the engineering constraints.

In this paper, a dynamic model of PAS without internal force is constructed. The trajectory planning of posture adjustment based on this model can improve the quality of cabin assembly.

This article is principally a case study establishing the existence of an internal labour market in British Rail, and its significance for the long‐term wage structure. Drawing on the work of Doeringer and Piore it outlines the advantages that internal labour markets would be expected to offer both employers and employees, and the implications which these have for the process of wage determination. It briefly reviews previous case studies supporting the importance of the role of comparisons, both internal and external, in wage bargaining; and then turns to the study of British Rail. Finding the characteristics expected of an internal labour market, it then establishes that the wage structure of the industry has demonstrated a considerable degree of stability over the period 1950‐85, despite considerable changes in relative productivities. This degree of consistency is regarded as being difficult to reconcile with the dominance of market forces in wage determination.

This paper is contributed to find the minimal mass prismatic tensegrity structures.

In the stable state of the structure with any given external force, the internal forces of the structure members are taken as the critical force to calculate the cross-sectional area, and the total mass of the structure can be obtained. Firstly, the mathematical model of prismatic tensegrity was built. Secondly, the stability of the tensegrity was analyzed based on the force equilibrium of one node, the force density relationship of elements was obtained. The deformation of p-bar tensegrity prism unit was studied with the same mass. The force of the structure under external force was analyzed.

(1) The length of bar and the structural radius are almost invariant, and the mechanical properties of 3-bar tensegrity prism is more outstanding; (2) theoretically, the mass of the structure is minimal while the projection of bar passes the center of the circle. Under the circumstances, the force of diagonal cable is 0 N, the vertical force component of bar cancels the axial external force.

The internal force is more complicated in a combined load case than in a single load case, and the influence of the combined load on the stress cannot be neglected. The purpose of this paper is to study the mechanical behavior of the flexible riser under combined load conditions of tension and internal pressure or external pressure.

The mechanical behavior of the flexible riser under combined load conditions is studied by numerical simulation with a nine-layer detailed finite element model. The layers of flexible riser are modeled separately, and the interactions between layers have been taken into consideration in numerical simulation.

Under tension and internal pressure or external pressure, the pressure armor will bear extra external pressure because of the squeezing actions between layers caused by tension, and the extra external pressure will increase proportionately with the increase of the tension. Under internal pressure and tension, the internal stress for tension armor was nearly unchanged compared to that under unique tension load, whereas under external pressure and tension, the change of internal stress for tension armor was significant. Prediction methods of internal force for pressure armor and tension armor under pressure and tension are given, and the result from the formula agrees well with the simulation results.

The prediction methods on the internal force of flexible riser proposed in this study are proven accurate, with numerical simulation results, and the prediction methods are convenient for engineering applications.

This study aims to focus on the factors triggering the adoption of corporate social responsibility (CSR) practices in a developing country context. The authors examine whether the adoption of CSR practices is triggered more by internal efficiency forces or external legitimation forces. As early adoptions of new systems are more likely driven by efficiency motives, the authors argue that CSR practices in developing countries at nascent stages are more likely adopted for efficiency rather than legitimation reasons.

A cross-sectional sampling design was used to collect data on the CSR practices of top listed Egyptian firms and multinationals operating in Egypt. The sample size is selected based on a purposive criterion sampling method. The final sample size consists of 110 companies operating in Egypt, which includes 54 local and 56 multinational companies. To examine the relationship between the explanatory variables of the study and CSR, multiple regression analysis was used.

Using data from 110 top listed local companies and multinational firms operating in Egypt, the results show a significant influence of internal corporate governance on CSR. Yet, the effects of external factors, specifically legal regulations and stakeholder pressures, on CSR are perceived to be insignificant. This finding contrasts studies from industrialized countries in the Western world where firms are often motivated to invest in CSR by external forces.

The results indicate that the adoption of CSR practices in large firms in Egypt is driven more by internal efficiency gains rather than external legitimacy pressures. The study thus presses the need for the effective enforcement of governmental laws and regulations to strengthen external institutional pressures and demands for socially responsible behavior.

The results of the study indicate a perceived absence of stakeholder pressure for CSR practices. As such, raising awareness for corporate accountability amongst Egyptian consumers, employees and the general public would increase corporate incentives to improve their social and environmental performance. In addition, the concept of CSR must be cultivated in the organizational culture where high value is placed on corporate ethics and managerial values.

This study provides insights about the predominant drivers of CSR in Egypt on two different levels; the organizational and the business environment. Salient links between CSR, internal corporate governance mechanisms and external drivers such as external stakeholder and legal pressures are explored. The results of the study also emphasize the importance of internal corporate governance mechanisms and how it is perceived to be the main driver of CSR in Egypt as opposed to external influences.

Consumer engagement has been designated as an approach to describing online interactions that more comprehensively reflects the nature of consumers’ interactive relationships in online brand communities. This paper aims to explore consumers’ brand community engagement in the context of Facebook brand pages. This research puts forth the hypothesis that consumers’ brand community engagement on Facebook is dependent upon two overarching themes: external social forces and internal personal forces.

Based on social impact theory, social identity theory and social exchange theory, a conceptual research model is developed and empirically tested through structural equation modelling using cross-sectional data of 460 Facebook brand fans.

The empirical results suggest that internal personal forces primarily positively influence brand community engagement, while external social forces can even impact consumers’ brand community engagement negatively.

Future research should test and validate the proposed model for specific categories and brands.

This paper offers help to online brand marketers to trigger meaningful engagement of consumers in a brand community on Facebook.

This paper examines the consumer engagement construct from a behavioural perspective in a defined social media context and highlights the peculiarities of online brand communities on Facebook that distinguish them from traditional brand communities. The research uses a strong theoretical foundation to develop a model that investigates the prevalent variables that influence consumers’ brand community engagement on Facebook.
