Over the last 30 years, research on Management Accounting Change as a way to understand the circumstances, forces and consequences related to the develop-ment and implementation of new techniques has grown in popularity. Accounting practices are context-dependent, as are changes to such practices. They require setting-specific studies that pay attention to the complexity of their enactment and to the elements that shape these practices. This paper presents a retrospective lon-gitudinal case study of a management accounting change project undertaken by a co-operative firm, and includes descriptive and explanatory aims. The factors po-tentially influencing the firm's decision to invest in management accounting change were related to a requirement for managerial efficiency, the need to legiti-mize the company to its external stakeholders, and the behavioral aptitude of in-dividual employees in the accounting and management sections. Against propo-nents' expectations, the project proved difficult to implement because of different forms of resistance and opposition, some explicit, others less obvious, encountered during implementation.. The study provides insights into the role played by man-agement control systems in creating and fostering trust in innovation and change.

And Control

The aim of the present tutorial paper is to recall notions from manifold calculus and to illustrate how these tools prove useful in describing system-theoretic properties. Special emphasis is put on embedded manifold calculus (which is coordinate-free and relies on the embedding of a manifold into a larger ambient space). In addition, we also consider the control of non-linear systems whose states belong to curved manifolds. As a case study, synchronization of non-linear systems by feedback control on smooth manifolds (including Lie groups) is surveyed. Special emphasis is also put on numerical methods to simulate non-linear control systems on curved manifolds. The present tutorial is meant to cover a portion of the mentioned topics, such as first-order systems, but it does not cover topics such as covariant derivation and second-order dynamical systems, which will be covered in a subsequent tutorial paper.

Biodiversity is the variability of between genetics, species, or ecosystems of living organisms within a specific region. Biodiversity is essential for sustaining healthy living networks and systems because it allows for a variety of food sources, medicine, and biological control, while also playing a significant role in atmospheric regulation, nutrient cycling, and pollination. Loss of biodiversity and ecosystem change increases the risk of the emergence or spreading of infectious diseases and global pandemics such as the Avian Influenza (AI H5N1). Biotechnology is one solution for reducing, and ultimately eliminating, the transmission of avian influenza. Traditional methods of treating infected animals, such as common vaccines, are temporary solutions that have no effect on the biodiversity of an ecosystem. Methods in animal biotechnology such as artificial insemination, embryo transfer, and <em>in vitro </em>fertilization have led to developments of cheaper, safer, and more effective vaccines. Livestock that have been treated for H5N1, as well as those that are healthy and have never been infected have proven to increase the diversity, leading to the elimination of specific issues. Similar effects are attainable if these animal biotechnology methods were to be used on poultry infected with the avian influenza virus.

Purpose This study aims to comprehensively examine the integration of organisational- and individual-level performance management systems (PMSs) in the context of public sector organisations (PSOs) of developing countries (DCs), by investigating the elements of PMSs in the studied organisation. Design/methodology/approach A case study in a large PSO of a developing country was conducted. The design of the study and the data analysis drew on Ferreira and Otley’s PMSs framework. Data were captured from electronic and printed document archives, online written interviews with participants and face-to-face interviews. The data then were triangulated and analysed thematically. Findings The study reveals a recursive relationship between culture and PMSs, and identifies conflicting regulatory requirements and a lack of information technology capacity led to the development of dual, loosely coupled PMSs in the studied organisation. Research limitations/implications The findings may not be generalisable beyond a large, PSO in a developing country; the study did not consider the linkages between the integration of organisational- and individual-level PMSs and other PMSs; the study looked at only two notions of culture; and the study asked participants to recall past events, so was retrospective in its design. Practical implications The findings illustrate the need for public sector managers and key policymakers to use both formal and informal control systems, together with technical and social integration mechanisms, as well as management accounting (MA) and human resources management (HRM) control approaches, when attempting to integrate organisational- and individual-level PMSs in the PSOs of DCs. Social implications Future studies may usefully investigate the integration of organisational- and individual-level PMSs in different contexts, consider culture and contextual factors when investigating the integration of organisational- and individual-level PMSs in different contexts, examine whether national culture also substantially impacts PMSs in other countries and attempt to inform the MA literature by drawing on HRM theory and research on individual-level PMSs. Such studies may help to address the gap between PMS theory and practice and better allow MA researchers to contribute to practice. Originality/value The study contributes to management control systems (MCSs) and PMSs literature by extending our understandings in the relationship between accounting and non-accounting controls, the contextual factors that affect PMSs and highlighting the importance of considering cultural context when integrating PMSs in the PSOs of DCs.

Critical Elements

PurposeThe purpose of this paper is to presents a new modeling approach that provides a measurement tool for evaluating the effectiveness of Project Control Systems (PCS) and the improvement of the project control capability as a part of an organization's project management processes.Design/methodology/approachThis study used a project management maturity approach to develop a measurement model of PCS success. The key elements in this model have been identified using the Fuzzy Analytic Hierarchy Process (FAHP) method to analyze data from a case study involving contractor companies in Saudi's petroleum and chemical industry.FindingsThe results identified six critical elements for PCS success: (1) Change Management, (2) Earned Value, (3) Baselined Plan, (4) Resource Loaded, (5) Progress Method and (6) Governance Program. In addition, Project Forecasting and Corrective Action Verification were identified as the main areas where clients and contractors need to focus for the effective deployment of a PCS.Practical implicationsThe results of this study were used to create a PCS Maturity Model (PCSMM) and a PCS Success Index (PCSSI). The value of this index can help project managers to identify the maturity level of their PCS and improvement areas that lead to enhanced project performance.Originality/valueThis research presents an alternative maturity model for PCS assessment that provides a practical tool to identify areas for improving the critical elements of PCS success. The study draws a clear distinction between overall project success and the success of the PCS.
