And Control

In the context of home, violence remains more accepted when committed against children than adults. Normalisation of parental violence has been documented in attitudinal surveys, professional practices, and legal regulation. For example, in many countries violent disciplining of children is the only legal form of interpersonal violence. This study explores the societal invisibility and normalisation of parental violence as a crime by analysing legislation and control policies regulating the division of labour and involvement between social welfare and criminal justice authorities. An empirical case study from Finland, where all forms of parental violence were legally prohibited in 1983, is used to elucidate the divergence between (criminal) law and control policies. The analysis demonstrates how normalisation operates at the policy-level where, within the same system of control that criminalised these acts, structural hindrances are built to prevent criminal justice interventions.

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.

PurposeDrawing on Simons's levers of control (LoC) framework, the primary aim of this study is to advance an understanding of the balance between empowerment and constraint in a non-profit UK organisation. In particular, this study examines the antecedents and manifestations of LoC (im)balance, in relation to employees' level of engagement with the control systems in place.Design/methodology/approachFor this study, 27 semi-structured interviews were conducted with different organisational members, from directors to non-managerial staff, to gain an in-depth appreciation of the main differences between managerial intentions in the design of management control systems (MCS) and employee perceptions regarding the role of such systems.FindingsThis research reveals that suppression of interactive systems and internal inconsistencies between different types of controls hinder the balance between empowerment and constraint. This imbalance is then found to have important consequences for employee buy-in, in some cases, defeating the purposes of control.Research limitations/implicationsThis study enhances our understanding of the gap between the design of control systems and the employee perceptions of it in an unusual organisational setting (non-profit and bringing together clinical and non-clinical staff and operations).Originality/valueThe study of MCS and its role in organisations has long been the focus of both academic and practitioner research. Yet, while extant literature focused on management's perspective on MCS, few studies have explored employees' attitudes and behaviours that accompany the implementation of control. What is more, little is known about the specific uses and behavioural outcomes of MCS in the context of non-profit organisations. Drawing on Simons's LoC framework, this paper addresses these gaps in the literature and investigates the balance between control and empowerment of employees in a UK non-profit organisation with significant clinical remit.

Plant Control

Nuclear power plants rely on Instrumentation and Control (I&C) systems for control, monitoring and protection of the plant. The original, analog designs used in most nuclear plants have become or soon will be obsolete, forcing plants to turn to digital technology. Many factors affect the design of replacement equipment, including long-term and short-term economics, regulatory issues, and the way the plant operates on a day-to-day basis. The first step to all modernization projects should involve strategic planning, to ensure that the overall long and short-term goals of the plant are met. Strategic planning starts with a thorough evaluation of the existing plant control systems, the available options, and the benefits and consequences of these options.

Purpose Prior literature provides little insight on how management control systems have responded to the growth of collaborative new product development (NPD). The purpose of this paper is to contrast the use of budgets to manage collaborative and in-house NPD and to consider the implications for enabling flexibility. Design/methodology/approach The paper reports on the findings of a case study company in the medical devices industry that uses two different business models for its NPD activities. While the company engages in in-house NPD for its own products, it also engages in collaborative NPD services with a range of customers. Findings The study illuminates how two types of budgets (annual and project) can have very different impacts on flexibility under different business models. The annual financial budgets imposed rigid constraints on in-house NPD and resulted in reduced flexibility, whereas in collaborative NPD, they had little impact on flexibility. Project budgets created hard operational constraints in collaborative NPD which generated a highly pressurised yet highly creative environment, whereas project budgets had little impact on flexibility in in-house NPD. Originality/value The study contributes detailed empirical insights into the control systems used to manage collaborative NPD from the supplier perspective, where creativity is largely responsive and contrasts these with the management of in-house NPD where creativity is largely expected. The authors also contribute an analysis of the key control systems and other factors that sustain flexibility in this highly pressurised open innovation environment.
