The field of Human Resource Management (HRM) has long recognized the importance of interpersonal influence for employee and organizational effectiveness. HRM research and practice have focused primarily on individuals’ characteristics and behaviors as a means to understand “who” is influential in organizations, with substantially less attention paid to social networks. To reinvigorate a focus on network structures to explain interpersonal influence, the authors present a comprehensive account of how network structures enable and constrain influence within organizations. The authors begin by describing how power and status, two key determinants of individual influence in organizations, operate through different mechanisms, and delineate a range of network positions that yield power, reflect status, and/or capture realized influence. Then, the authors extend initial structural views of influence beyond the positions of individuals to consider how network structures within and between groups – capturing group social capital and/or shared leadership – enable and constrain groups’ ability to influence group members, other groups, and the broader organizational system. The authors also discuss how HRM may leverage these insights to facilitate interpersonal influence in ways that support individual, group, and organizational effectiveness.

This chapter is about how leaders attempt to move from traditional to shared leadership and why they often cannot. We develop a new theoretical framework to examine whether leaders are willing to shift control from themselves to their followers and thus promote shared leadership in their teams. We argue that control shifts, while necessary for shared leadership, are particularly difficult for leaders to enact. This is because leadership is often closely bound with power and status in the organization, a reality of organizational life that is often overlooked in the quest for new forms of leadership, such as shared leadership. Our contribution lies in examining leaders’ ability to enact shared leadership through the lenses of primary and secondary control, and situating control shift in the context of global leadership including selected cultural dimensions, complexity, and paradoxes.

Depending on an experimental approach to find optimal parameters for producing fully dense (relative density > 99%) Inconel 718 (IN718) components in the selective laser melting (SLM) process is expensive and offers no guarantee of success. Accordingly, this study aims to propose a multi-scale simulation framework to guide the choice of processing parameters in a more pragmatic manner.

In the proposed approach, a powder layer, ray tracing and heat transfer simulation models are used to calculate the melt pool dimensions and evaporation volume corresponding to a small number of laser power and scanning speed conditions within the input design space. A layer-heating model is then used to determine the inter-layer idle time required to maximize the temperature convergence rate of the solidified layer beneath the power bed. The simulation results are used to train surrogate models to construct SLM process maps for 3,600 pairs of the laser power and scanning speed within the input design space given three different values of the underlying solidified layer temperature (i.e., 353 K, 673 K and 873 K). The ideal selection of laser power and scanning speed of each process map is chosen based on four quality-related criteria listed as follows: without the appearance of key-hole melting; an evaporation volume less than the volume of the d90 powder particles; ensuring the stability of single scan tracks; and avoiding a weak contact between the melt pool and substrate. Finally, the optimal laser power and scanning speed parameters for the SLM process are determined by superimposing the optimal regions of the individual process maps.

The feasibility of the proposed approach is demonstrated by fabricating IN718 test specimens using the optimal processing conditions identified by the simulation framework. It is shown that the maximum density of the fabricated parts is 99.94%, while the average density is 99.88% and the standard deviation is less than 0.05%.

The present study proposed a multi-scale simulation model which can efficiently predict the optimal processing conditions for producing fully dense components in the SLM process. If the geometry of the three-dimensional printed part is changed or the machine and powder material is altered, users can use the proposed method for predicting the processing conditions that can produce the high-density part.

The study critically evaluates the theory of International Financial Reporting Standards (IFRS) implementation in an attempt to provide directions for future research. Using the extensive structured review of literature using the Scopus database tool, the study reviewed 79 articles, and in particular the topic-related 57 articles were analysed. Nine journals contribute to 51% of articles (29 of 57 articles). In particular, the three journals published 15 articles: Critical Perspectives on Accounting (7), Accounting, Organizations and Society (4), and Journal of Applied Accounting Research (4). In total, 83% (47 of 57) of the articles were published 2009–2018. A total of 1,168 citations were found from 45 articles since 12 articles were without citations. The highest cited authors were Ball (2006) – 410 citations, Kothari, Ramanna, and Skinner (2010) – 135 citations, and Napier (1989) – 85 citations. In particular, five theories have been used widely: institutional theory (13), accounting theory (6), agency theory (3), positive accounting theory (3), and process theory (2). Future studies’ focus could be on theory implications in IFRS adoption/implementation studies in a country or a group of countries’ experience. Future studies could also focus on various theories rather depending on a single theory (i.e. institutional theory).

The purpose of this paper is to implement a closed loop regulated bidirectional DC to DC converter for an application in the electric power system of more electric aircraft. To provide a consistent power supply to all of the electronic loads in an aircraft at the desired voltage level, good efficiency and desired transient and steady-state response, a smart and affordable DC to DC converter architecture in closed loop mode is being designed and implemented.

The aircraft electric power system (EPS) uses a bidirectional half-bridge DC to DC converter to facilitate the electric power flow from the primary power source – an AC generator installed on the aircraft engine’s shaft – to the load as well as from the secondary power source – a lithium ion battery – to the load. Rechargeable lithium ion batteries are used because they allow the primary power source to continue recharging them whenever the aircraft engine is running smoothly and because, in the event that the aircraft engine becomes overloaded during takeoff or turbulence, the charged secondary power source can step in and supply the load.

A novel nonsingular terminal sliding mode voltage controller based on exponential reaching law is used to keep the load voltage constant under any of the aforementioned circumstances, and its performance is contrasted with a tuned PI controller on the basis of their respective transient and steady-state responses. The former gives a faster and better transient and steady-state response as compared to the latter.

This research gives a novel control scheme for incorporating an auxiliary power source, i.e. rechargeable battery, in more electric aircraft EPS. The battery is so implemented that it can get regeneratively charged when primary power supply is capable of handling an additional load, i.e. the battery. The charging and discharging of the battery is carried out in closed loop mode to ensure constant battery terminal voltage, constant battery current and constant load voltage as per the requirement. A novel sliding mode controller is used to improve transient and steady-state response of the system.

A systems perspective of waste management allows an integrated approach not only to the five basic functional elements of waste management itself (generation, reduction, collection, recycling, disposal), but to the problems arising at the interfaces with the management of energy, nature conservation, environmental protection, economic factors like unemployment and productivity, etc. This monograph separately describes present practices and the problems to be solved in each of the functional areas of waste management and at the important interfaces. Strategies for more efficient control are then proposed from a systems perspective. Systematic and objective means of solving problems become possible leading to optimal management and a positive contribution to economic development, not least through resource conservation. India is the particular context within which waste generation and management are discussed. In considering waste disposal techniques, special attention is given to sewage and radioactive wastes.

The purpose of this study is to review a synthesis of International Financial Reporting Standards (IFRS) implementation in developing countries in an attempt to provide directions for future research. The in-depth analysis was performed with the use of the data analysis tool available in the Scopus databases. The study initially reviewed 145 papers and in particular 35 papers were analysed. Fifteen articles (43%) were published in seven journals including International Journal of Accounting, Critical Perspectives on Accounting, Advances in Accounting, International Journal of Accounting and Information Management, Asian Review of Accounting, Journal of Applied Accounting Research, and Asian Journal of Business and Accounting. Specifically, 89% citations were from 14 articles, but 9 (25%) articles were without any citations. Most of the studies focus on qualitative followed by quantitative, and very few studies were based on mixed methods. Researchers should focus on few areas for future research on IFRS implementation in developing countries including theory implications, policy prescriptions, and case of particular standard.

The study aims at reviewing a synthesis of the impact of culture on the implementation of International Financial Reporting Standards (IFRS) in an attempt to provide directions for future research. From the extensive structured review of literature from 106 articles, 23 related articles were analysed. The SCOPUS database tool was used to search the articles. Over the last three decades (188–2018), a total of 23 articles were published from 18 journals. Four journals contribute to 39% articles including Advances in Accounting (2), Critical Perspectives on Accounting (2), European Research Studies Journal (2), and International Journal of Accounting (3). In total, 22% of the articles had no citations. Most of the articles used Hofstede’s theory of culture and utilised quantitative data analysis. Interestingly, 48% of the articles did not apply any theory. The study calls for future research on comparative and regional and other theories to inform the policymakers on cultural implication on global IFRS implementation.

This study empirically aims to examine the relation between CEO power and firm engagement in corporate social responsibility (CSR). It undertakes an in-depth analysis of how the structural, ownership and expert dimensions of CEO power affect individual dimensions of CSR.

This study uses ordinary least squares and industry fixed-effects regressions. It also uses instrumental variable-generalized method of moment regressions to test the robustness of empirical results.

Results indicate that CEO power is negatively related to CSR. However, the relation between CEO power and CSR is influenced by CSR strengths, as power is negatively related to CSR strengths and is not related to CSR concerns. Results also indicate that the structural and ownership dimensions of CEO power are negatively related to CSR, and the expert dimension has no significant effect on CSR. Moreover, results show that CEO power is not related to the product dimension of CSR performance.

CEO power is measured using the structural, ownership and expert dimensions of power. However, CEOs also acquire power through social networks and connections outside the corporation which is not covered in this study.

This study uses comprehensive measures of CEO power and CSR. It is the first study that examines the effect of dimensions of CEO power on individual dimensions of CSR performance.
