Abstract
Purpose
Aims to research the possibilities of using piezoelectric technology to improve accuracy and other characteristics of parallel servo grippers.
Design/methodology/approach
The paper presents in detail two different kinds of developed two‐fingered servo grippers based on piezoelectric technology with parallel moving mechanics. The first gripper is based on standing wave ultrasonic motors. The other gripper is a traditional gripper, the characteristics of which have been improved with integrated piezoelectric stack actuators. Both servo grippers have been tested and the test results and experiences are introduced in the paper.
Findings
It is possible to improve the accuracy and characteristics of a parallel servo gripper with piezoelectric technology.
Research limitations/implications
In the future it is necessary to concentrate on the mechanical design of gripper bodies and the fingers. Grasping force feedback signal should be even more linear and noiseless.
Practical implications
Piezoelectric stack actuator's limited displacement is a problem in many practical applications when elastic or rough surface parts are handled. When integrated piezoelectric stacks are used with servo grippers, it is very important to focus on gripper's mechanical design and especially on the mechanical rigidity for getting the best possible results.
Originality/value
Further developed versions of these servo grippers can be used in high accuracy industry applications instead of traditional servo gripper technologies.

Abstract
Currently, adhesive films are replacing glue in many applications in semiconductor packaging and microelectronic assembly. When adhesive films are used to mount components on a PCB, the success of the automatic joining operation depends on many different things. Manufacturers of adhesives use three main values when they are discussing processing parameters in their data sheets. The paper describes in detail the concept of the developed assembly environment for making test joints of miniature and MEMS components using adhesive films.

Abstract
Purpose
Interest has grown in how management controls operate together as a package of interrelated mechanisms. This study aims to contribute to the topic by focusing on a single industry in one country, addressing controls in medium-sized enterprises (MEs). It explores how accounting and other forms of control commonly combine and the associations these combinations have with firm characteristics and context.
Design/methodology/approach
This study used a cross-sectional sample of 242 firms. Data were collected in 2015 from a survey of the Italian mechanical-engineering industry.
Findings
The MEs studied used two different control configurations. One group relatively strongly emphasized most studied controls, except for centralizing decision-making and strong hierarchy; the other relied on centralization and emphasized other controls less. Size, task programmability, outcome measurability, complexity in terms of the extensiveness of the product range and environmental unpredictability can predict the configuration in use.
Originality/value
No broad-based empirical evidence on control configurations in MEs currently exists. Previous research has focused on to what extent control systems affect business effectiveness or efficiency, without assessing how, and in which contexts, they combine.

Abstract
Purpose
The purpose of this paper is to investigate the initiation of accounting information system projects. Specifically, it examines the role of the predictive analytics (PA) project initiator in the integration of financial and operational sales forecasts.
Design/methodology/approach
The study uses a field study method to address the studied phenomenon in eight Finnish companies that have recently adopted PA systems. The data are primarily based on 19 interviews in the companies and five interviews with the PA consultants.
Findings
The authors found that initiators appear to play a major role regarding the degree of integration of financial and operational sales forecasts. The initiators from an accounting function have a tendency to pay more attention to the integration than the representatives from other functions, such as operations and sales.
Practical implications
The study also makes a practical contribution to companies in showing and discussing the important role of the accounting department as an initiator of a project if the target is to achieve a tight coupling of financial and operational forecast figures, i.e., “one set of numbers”.
Originality/value
Even though companies have increasingly adopted PA systems in recent years, we still know little about how the initiation affects the design of accounting information systems overall. The central contribution of the paper, therefore, is to show that if a PA project is initiated by the accounting department, data integration becomes more likely. It contributes also to the discussion related to the appropriateness of data integration in the context of forecasting.

Abstract
Purpose
This study examines the relationship between the use of management controls and the perception of meaningful work. Meaningful work is an important driver of individual performance of managers, and employees and can be enabled by sufficient use of management controls. The purpose of this paper is to address this issue.
Design/methodology/approach
Based on bibliometric analyses and a structured literature review of academic research studies from the organizational, management and accounting literature, the authors develop a conceptual model of the relationship between the use of management controls and the perception of meaningful work.
Findings
First, the authors propose that the use of formal management controls in a system (i.e. the levers of the control framework) is more powerful than using unrelated formal controls only. Second, they suggest that the interaction of a formal control system together with informal controls working as a control package can even stretch the perception of meaningful work. Third, they argue that the intensity of the control use matters to enhance the perception of meaningful work (inverted u-shaped relationship).
Originality/value
This study presents the first conceptual model of the relationship between the use of management controls and the perception of meaningful work. It provides valuable implications for practice and future research in the field of performance management.

Abstract
Purpose
This study aims to examine the interplay between ownership structure (organisational form) and management control system (MCS) design as governance structures within Australian primary health-care organisations (PHOs), seeking support for the suggestion that professional services will be most efficiently and effectively provided in organisations that have internal governance that is matched to their ownership form.
Design/methodology/approach
The analysis is based on a series of in-depth investigations into the MCS choices made by seven Australian PHOs. Arguing that the degree of information impactedness is inversely related to the level of general practitioner (GP) ownership, organisations where more than 50 per cent of the GPs working within the practice are owners are classified as “high ownership” (“low information impactedness”). The adoption by high-performing organisations of their predicted MCS archetype according to Speklé’s development is then interpreted as representing empirical support.
Findings
The findings provide uniform support for the importance of the match between ownership structure and internal governance mechanisms. As predicted, the two high-performing, high member-owned organisations reported MCS resembling exploratory archetypes, the three high-performing, low member-owned organisations reported MCS consistent with a boundary archetype and the two low-performing organisations reported little emphasis on any control.
Research limitations/implications
This study provides evidence of the importance of the appropriate match between ownership structure and internal governance mechanisms for PHOs.
Practical implications
This study has potential to assist managers, owners and advisors to optimise MCS design in professional services organisations where there is heterogeneous ownership by professionals.
Originality/value
This study is one of the few attempts to provide empirical support for the assertion of the importance of a match between ownership structure and MCS design. It also represents one of the few attempts to provide empirical support for Speklé’s (2001) control archetypes, here the boundary and exploratory archetypes, archetypes that are applicable within important sectors of the economy, notably the professional services sector.
