Complementary projector for null-space stiffness control of redundant assembly robot arm
Authors: Lukic Nikola , Petrovic Petar B. 
Published: July 2019

Purpose
Stiffness control of redundant robot arm, aimed at using extra degrees of freedom (DoF) to shape the robot tool center point (TCP) elastomechanical behavior to be consistent with the essential requirements needed for a successful part mating process, i.e., to mimic part supporting mechanism with selective quasi-isotropic compliance (Remote Center of Compliance – RCC), with additional properties of inherent flexibility.

Design/methodology/approach
Theoretical analysis and synthesis of the complementary projector for null-space stiffness control of kinematically redundant robot arm. Practical feasibility of the proposed approach was proven by extensive computer simulations and physical experiments, based on commercially available 7 DoF SIA 10 F Yaskawa articulated robot arm, equipped with the open-architecture control system, system for generating excitation force, dedicated sensory system for displacement measurement and a system for real-time acquisition of sensory data.

Findings
Simulation experiments demonstrated convergence and stability of the proposed complementary projector. Physical experiments demonstrated that the proposed complementary projector can be implemented on the commercially available anthropomorphic redundant arm upgraded with open-architecture control system and that this projector has the capacity to efficiently affect the task-space TCP stiffness of the robot arm, with a satisfactory degree of consistency with the behavior obtained in the simulation experiments.

Originality/value
A novel complementary projector was synthesized based on the adopted objective function. Practical verification was conducted using computer simulations and physical experiments. For the needs of physical experiments, an adequate open-architecture control system was developed and upgraded through the implementation of the proposed complementary projector and an adequate system for generating excitation and measuring displacement of the robot TCP. Experiments demonstrated that the proposed complementary projector for null-space stiffness control is capable of producing the task-space TCP stiffness, which can satisfy the essential requirements needed for a successful part-mating process, thus allowing the redundant robot arm to mimic the RCC supporting mechanism behavior in a programmable manner.
Institutions, situated rationality and agency in management accounting
Authors: ter Bogt Henk J. , Scapens Robert W. 
Published: July 2019

Purpose
Drawing on recent research, which recognises the situated nature of accounting practices, the purpose of this paper is to extend the Burns and Scapens (B&S) framework and to illustrate its potential for studying the situated nature of management accounting practices. The extended framework distinguishes field-level institutions (which the authors term broader institutions) and institutions within the organisation (which the authors term local institutions). To extend the B&S framework the authors draw on recent debates in institutional theory, both new institutional sociology, where the focus is now on the institutional logics perspective, and old institutional economics, where there has been debate about the relationship between institutions and actions.

Design/methodology/approach
While the B&S framework focussed on institutions within the organisation, the extended framework explicitly recognises institutions which extend beyond the boundaries of the organisation. It also recognises the way in which rationality and deliberation are related to human agency, as well as the power of specific individuals and/or groups to impose new rules. To illustrate the usefulness of the extended framework the research note draws on a recent study of performance measurement in the Accounting and Finance Groups of the Universities of Groningen and Manchester.

Findings
It is argued that local institutions within the organisation combine with the broader institutions to shape the forms of situated rationality which are applied by individuals and groups within the organisation. Different groups within an organisation (e.g. engineers and accountants) can have different forms of situated rationality, and contradictions in these forms of rationality can be a source of institutional change or resistance to change within the organisation, and can explain why accounting changes can by implemented in different ways in different organisations and also in different parts of the same organisation.

Originality/value
The extended framework will be useful for studying: (1) how situated rationalities evolve within an organisation, more specifically how they are shaped by both local and broader institutions; and (2) how prevailing situated rationalities shape the responses to accounting change.
Organic companies’ business models: emerging profiles in Italian bio-districts
Authors: Truant Elisa , Broccardo Laura , Zicari Adrian 
Published: July 2019

PurposeThe purpose of this paper is to investigate the “organic” phenomenon within a sample of companies and try to depict the main business model (BM) features and profiles.Design/methodology/approachThe methodology used for the current research is twofold: first, a literature analysis has been conducted in order to highlight the gap in the existing literature. Then, the different BM profiles were investigated through a survey questionnaire conducted among a sample of Italian organic companies and organic districts. The evidence from the literature review supported the researchers during the empirical phase.FindingsFrom the literature review, it emerged that studies on the BMs of organic companies and organic districts need a deep analysis and a literature gap on this topic has emerged. From the BM point of view, clustering sheds light on proactive companies, which are characterized by a higher level of education among entrepreneurs, greater investments in the business and the sale of products within and outside of the domestic market.Research limitations/implicationsLimitations include the number of answers collected through surveys and the focus on a single country.Practical implicationsThe main practical implication focuses on the regulatory bodies that should better understand the BMs characteristics implementing adequate policies for the development of organic companies and districts.Originality/valueThe main practical implication focuses on the regulatory bodies that should better understand the BM characteristics and implement adequate policies for the development of organic companies and districts.
Increasing the efficiency and efficacy of demolition through computerised 4D simulation
Authors: Kunieda Yoichiro , Codinhoto Ricardo , Emmitt Stephen 
Published: July 2019

Purpose
The purpose of this paper is to develop a novel tool to support decision making for enhanced demolition process efficiency and material waste sortability through computerised 4D motion workflow simulation.

Design/methodology/approach
A time-lapse evaluation model was developed to classify and estimate the impact of building demolition processes and material waste recovery. The dynamic assessment of demolition, collision and mechanical impact was measured through computerised 4D motion game and physics engines. Waste recovery and treatment complemented the simulation algorithm. The simulation of the information workflow was tested through case study using two demolition strategies.

Findings
The simulation successfully estimated the efficiency and efficacy of the different demolition strategies. Thus, simulation results can potentially support better decision making related to the definition of demolition strategies associated with recycling and re-use targets.

Research limitations/implications
The simulation was limited to a simple machine-led demolition strategy. Further research is required to understand the impact of complex machine mechanic movements and processes on complex building fabrics.

Originality/value
Modelling and evaluating the demolition process and its impact on material waste recovery with a time dimension is novel. The comparative analysis of quantitative data allows demolition professionals to find optimal and more sustainable demolition solutions and more efficient and safer implementation on site. It also contributes to a better understanding of the relationship between demolition strategy and waste sortability. This research represents a significant advancement in applied computing for building demolition waste recycling and notably, it improves the quality of information available in the definition of building demolition strategies.
Egyptian women supervisory empowerment behaviors on well-being outcomes
Authors: El-Kot Ghada , Burke Ronald J. , Fiksenbaum Lisa M. 
Published: July 2019

PurposeThis paper aims to examine the relationship of perceived supervisor empowerment behaviors and feelings of personal empowerment with important work and well-being outcomes in a sample of Egyptian women managers and professionals.Design/methodology/approachData were collected from 155 managerial and professional women using anonymously completed questionnaires. Respondents were relatively young; had university educations; had the short job and organizational tenures; held various levels of management jobs; and worked in a range of functions. All measures used here had been used and validated previously by other researchers.FindingsWork outcomes included job satisfaction, career satisfaction, work engagement, work-family and family-work conflict, emotional exhaustion/burnout, life satisfaction and intent to quit. Both perceived levels of supervisory/leader empowerment behaviors and self-reported feelings of empowerment had significant relationships with the majority of work and well-being outcomes.Research limitations/implicationsData were collected using self-report questionnaires with the small risk of response set and common method biases. Second, all data were collected at one point in time making it challenging to address issues of causality. Third, all respondents came from the two largest cities in Egypt, Cairo and Alexandria; thus, the extent to which our findings would generalize to managerial and professional women and men is indeterminate. Fourth, it was not possible to determine the representativeness of our sample as well.Practical implicationsPractical implications of these findings along with future research directions are offered. Practical applications include training supervisors on empowerment behaviors, and training all employees on the benefits of personal empowerment and efficacy and ways to increase them.Social implicationsA number of ways to increase levels of empowerment of both front-line employees and managers have been identified. These include increasing employee participation in decision-making, delegating authority and control to these employees, creating more challenging work roles through job redesign, leaders sharing more information and leaders providing more coaching and mentoring to their staff. At the micro level, increasing levels of employee self-efficacy through training and more effective use of their work experiences will increase personal empowerment and improve work outcomes.Originality/valueRelatively little research has been undertaken on women in management and human resource management in Egypt.
An empirical study on life cycle assessment of double-glazed aluminium-clad timber windows
Authors: M. Asif 
Published: July 2019

Purpose
Life cycle assessment (LCA) is a useful tool to determine the environmental performance of materials and products. The purpose of this paper is to undertake the LCA of double-glazed aluminium-clad timber windows in order to determine their environmental performance.

Design/methodology/approach
The scope of the LCA study covers the production and the use of windows over a 30-year life span. The LCA exercise has been carried out by auditing the materials and processes involved in the making of the windows. Windows production facilities were visited to investigate the respective quantities and embodied energy of the major constituting materials, i.e. timber, aluminium, glass, infill gases and auxiliary components. The main processes involved, i.e. powder coating of aluminium cladding profiles, glazing unit production and window assembly, were also examined. SimaPro software was used to calculate the environmental impacts associated with the windows for three types of glazing infills: Argon (Ar), Krypton (Kr) and Xenon (Xe).

Findings
Embodied energy of a standard sized (1.2 m×1.2 m) double-glazed aluminium-clad timber window is found to be 899, 1,402 and 5,400 MJ for Argon (Ar), Krypton (Kr) and Xenon (Xe) infill gases, respectively. It is also found that an Argon-filled window can lose 95,130 kWh of energy resulting into over 37,000 kg of CO2 emissions.

Originality/value
Besides carrying value for research community, the findings of this study can help the building and construction industry adopt windows that are energy-efficient and environmentally less burdensome. It can also help the concerned legislative bodied.
The effects of trust and distrust on ICT-enabled information sharing in supply chains
Authors: Mirkovski Kristijan , Davison Robert M. , Martinsons Maris G. 
Published: July 2019

PurposeDrawing on transaction cost economics (TCE) and social exchange theory (SET), the purpose of this paper is to explain why and how external environment, governance structures and interpersonal relationships influence information and communication technology (ICT)-enabled information sharing in supply chains (SCs) of small- and medium-sized enterprises (SMEs) from developing economies.Design/methodology/approachThe authors adopt a theory-building approach using a multiple case study design, including four SMEs operating in SCs from two developing economies (i.e. Republic of North Macedonia and People’s Republic of China), in which the authors conduct both within-case and cross-case analyses.FindingsSocial bonds (known as vrski in Macedonian and guanxi in Chinese) were found to govern buyer–supplier exchanges by supporting the establishment of personal trust and the reduction of distrust. These social bonds compensate for the institutional deficiencies in developing economies and thus encourage ICT-enabled information sharing by SMEs in their SCs.Research limitations/implicationsBy applying the theoretical perspectives of TCE and SET to the cross-case analysis, the authors develop nine propositions to explain ICT-enabled information sharing and its interdependencies with external environment, governance structures and interpersonal relationships in developing economies. Further research is recommended to refine and test the generalizability of the theoretical model.Practical implicationsFirms have to develop and nurture social bonds with their suppliers from developing economies to reduce risks related to the environmental uncertainty and institutional voids. This can increase trust and decrease distrust associated with ICT-enabled information sharing.Originality/valueThe study examines why and how external environment (environmental uncertainty and institutional environment), social bonds (vrski and guanxi) and interpersonal mechanisms (trust and distrust) influence ICT-enabled information sharing of SMEs operating in developing economies.
Prevalence and experiences of food insecurity among immigrant women connected to perinatal programs at a community-based organization in Edmonton, Canada
Authors: Quintanilha Maira , Mayan Maria J. , Jarman Megan , Bell Rhonda C. 
Published: July 2019

PurposeThe purpose of this paper is to investigate the prevalence of household food insecurity among immigrant women connected to perinatal programs offered through a community-based organization in Edmonton, and to explore their experiences in coping with food insecurity.Design/methodology/approachThis study utilized a mixed methods research design. A community-based participatory research approach was used to engage health workers who were connected to immigrant women and families through the Multicultural Health Brokers Cooperative in Edmonton. Through the health workers a sample of 213 immigrant women connected to their perinatal programs completed the Household Food Security Survey. Following the survey, 17 women completed semi-structured interviews which were analyzed using content analysis.FindingsThe vast majority of women (94 percent (n=199)) lived in food insecure households, and 53 percent (n=112) in severely food insecure. In semi-structured interviews, women specifically described not having enough money to buy vegetables, fruit and meat, and perceiving a lack of control over foods they ate and offered to their families.Practical implicationsThis study highlights the need for support to be provided to immigrant families for acquiring healthy food in Canada.Originality/valueThe mixed methods design with a decent sample of often underrepresented research participants highlights an area in need of further research and greater support.
Investigating the relationship between perception of an organisation’s ethical culture and worker motivation
Authors: Colaco Beverly , Loi Natasha M. 
Published: July 2019

Purpose
This study aims to examine whether an individual’s perception of the ethical culture of their organisation could be used to predict their work motivation.

Design/methodology/approach
Using the corporate ethical virtues model as a foundation, the role of distributive justice was explored through the development of a composite measure for assessing ethical organisational culture. The resulting six-factor solution was then used. Australian employees (N = 330; Mage = 38.40) completed an online survey examining perceptions of ethical culture, distributive justice and work motivation.

Findings
Results indicated that higher work motivation was associated with a higher perception of an organisation’s ethical culture. Additionally, the six dimensions of ethical culture accounted for significant variance in worker motivation, with factors relating to congruency of peers, clarity and feasibility being the best predictors.

Originality/value
This study provides useful cues for future research and interventions enabling organisations to take a more targeted approach to influence their ethical culture and, consequently, an individual’s motivation to work.
CEO career concerns and expectations management
Authors: Alfonso Elio , Brooks Li-Zheng , Simonov Andrey , Zhang Joseph H. 
Published: July 2019

PurposeThe purpose of this paper is to examine the impact of career concerns on CEOs’ use of expectations management to meet or beat analysts’ quarterly earnings forecasts. The authors posit that early career-stage CEOs are less (more) likely to use expectations management than are late career-stage CEOs if the market views expectations management as an opportunistic strategy (efficient process) due to reputational capital concerns.Design/methodology/approachThe authors obtain data for CEO career stages and CEO compensation from ExecuComp, analyst earnings forecasts from the detailed I/B/E/S database, financial statement data from quarterly Compustat and stock returns from the daily CRSP database over the period 1992–2013.FindingsThe results are consistent with the opportunistic hypothesis and early-stage CEOs seeking to build reputational capital by avoiding the perception of engaging in an inefficient managerial strategy. The authors find robust evidence that late career-stage CEOs are more likely to engage in expectations management than early career-stage CEOs. Furthermore, the authors show that late career-stage CEOs tend to employ expectations management to boost the value of their equity-based compensation.Research limitations/implicationsThe findings have important implications because the authors document a different implication of the “horizon problem” related to CEOs’ opportunistic forecasting behavior and the manipulation of analysts’ forecasts for CEOs who are approaching retirement.Practical implicationsThe results have practical implications for analysts who provide earnings forecasts for firms whose CEOs are in early or late career stages and for investors who use such analysts’ forecasts in firm valuation models.Originality/valueThe authors contribute to the literature on expectations management by documenting how reputational incentives of CEOs affect the likelihood that managers engage in expectations management. The authors show that an important managerial incentive to engage in expectations management is CEO career concerns. Furthermore, the authors show that CEOs who are in early stages of their careers choose not to engage in expectations management due to the market’s perceived degree of opportunism pertaining to this strategy.
Evidence-based practice adaptation during large-scale implementation: a taxonomy of process and content adaptations
Authors: Aarons Gregory A. , Askew Rachel A. , Green Amy E. , Yalon Alexis J. , Reeder Kendal , Palinkas Lawrence A. 
Published: July 2019

PurposeThe purpose of this paper is twofold: first, to identify the types of adaptations made by service providers (i.e. practitioners) during a large-scale US statewide implementation of SafeCare®, an evidence-based intervention to reduce child neglect; and second, to place adaptations within a taxonomy of types of adaptations.Design/methodology/approachSemi-structured interviews and focus groups were conducted with 138 SafeCare providers and supervisors. Grounded theory methods were used to identify themes, specific types of adaptations and factors associated with adaptation.FindingsAdaptations were made to both peripheral and core elements of the evidence-based practice (EBP). The taxonomy of adaptations included two broad categories of process and content. Process adaptations included presentation of materials, dosage/intensity of sessions, order of presentation, addressing urgent concerns before focusing on the EBP and supplementing information to model materials. Content adaptations included excluding parts of the EBP and overemphasizing certain aspects of the EBP. Adaptations were motivated by client factors such as the age of the target child, provider factors such as a providers’ level of self-efficacy with the EBP and concerns over client/provider rapport. Client factors were paramount in motivating adaptations of all kinds.Research limitations/implicationsThe present findings highlight the need to examine ways in which adaptations affect EBP implementation and sustainment, client engagement in treatment, and client outcomes.Practical implicationsImplementers and EBP developers and trainers should build flexibility into their models while safeguarding core intervention elements that drive positive client outcomes.Originality/valueThis study is unique in examining and enumerating both process and content types of adaptations in a large-scale child neglect implementation study. In addition, such adaptations may be generalizable to other types of EBPs.
