Authors: Schiavo Gustavo , Korzenowski Andre Luis , Soares Batista Eduardo Roberto , Souza Davenilcio Luiz de , Scavarda Annibal 
Published: March 2018

PurposeThe purpose of this paper is to analyze the perception of the cold chicken meat value in its supply chain and how to manage the influence of quality demands in this supply chain. It is based on the views that retails and restaurants have about the main quality aspects required to meet their end customers.Design/methodology/approachThis paper surveyed 135 respondents from restaurants, butcheries, supermarkets, and convenience stores located in the Southern Brazilian metropolitan area. Principal component analysis followed by quality function deployment was performed to analyze the data.FindingsThe principal component analysis results in seven factors: product quality and flexibility of delivery; supply flexibility; responsiveness to market changes and product assortment; measurements of the inventory and competitiveness; product specificity; product availability and specificity cost; and delivery frequency. The comparative study on the steps of the process between restaurants and retailers shows that distribution, cutting and packaging are the key process steps in this chain.Practical implicationsThe results show what process steps must be prioritized to comply with the customers’ quality requirements. Since the most important process steps are different for different customers, companies may elect what steps require more attention to satisfy the most profitable customer types.Originality/valueSeveral studies are found in the literature that present a theoretical discussion on the quality demands of perishable products. The management of factors related to the process steps can help members of the supply chain in their decision-making processes. The contribution of this research is to identify, by an applied study, how the demanded quality aspects should be considered by the poultry industry to satisfy customers in different market segments.
Business process management – at the crossroads
Authors: Klun Monika , Trkman Peter 
Published: March 2018

PurposeBusiness process management (BPM) has attracted much focus throughout the years, yet there have been calls questioning the future of BPM. The purpose of this paper is to explore the current state of the field through a dynamic literature review and identify the main challenges for its future development.Design/methodology/approachA dynamic co-citation network analysis identifies the “evolution” of knowledge of BPM and the most influential works. The results present the developed BPM subthemes in the form of clusters.FindingsThe focus within the field has shifted from facilitating wide-ranging business performance improvements to creating introverted optimizations within a particular BPM subgroup. The BPM field has thus experienced strong fragmentation throughout the years and has accrued into self-fueling subareas of BPM research such as business process modeling and workflow management. Those subareas often neglect related disciplines in other management, process modeling and organizational improvement fields.Research limitations/implicationsThe study is limited by the initial keyword choice of the authors. The subsequent co-citation analysis ameliorates the subjectivity since it produces a data set and contributions based on references.Originality/valueA new combination of historical development and the state-of-the-art of the BPM field, by employing a co-citation and cluster analysis. This dynamic literature review presents the current state of the theoretical core and attempts to identify the crossroads that BPM has reached. The study can be replicated in the future to track the changes in the field.
New advanced concept of the flying capacitor asymmetric multilevel voltage source inverter
Authors: Jabberi Henda , Ben Ammar Faouzi 
Published: March 2018

Purpose
To improve the voltage quality in AC adjustable high-power-speed-drive applications, the purpose of the paper is to provide a large number of output levels without increasing the number of commutation cells in the three-phase, n-cells flying capacitor voltage source asymmetric Multilevel Inverter (MI). The concept is based on the selection of different ratios between the breakdown voltages of two successive power devices. The new mathematical model is developed under various ratios, allows a thorough investigation of the harmonic distortions, flying capacitor energy storage, flying capacitor voltage balancing controllability and blocking voltage insulated gate bipolar transistor (IGBT) capability.

Design/methodology/approach
The asymmetrical design provides a large number of output levels without increasing the number of commutation cells. The important new analytical expression of capacitors voltage distribution is derived and extended to any ratio between the switch breakdown voltages of two successive power devices.

Findings
The detailed simulation study of the proposed concept has been carried out using MATLAB/Simulink. The power switches control of the three-phase three-cell MI is assured by new phase-shifted-multi-carrier pulse width modulation. The space vector representation is used to show the regular and irregular step output voltage in the complex plan (α,β).

Originality/value
In the paper, the n cells flying capacitor inverter, which typically operates in the (n + 1) levels mode, was extended to (n + 2), (n + 3) … until 2n levels with regular or irregular step output voltage. Consequently, the claimed advantages of the asymmetric MI are to improve power quality by reducing harmonic distortions and to reduce the requirement on capacitive energy storage in the circuit.
Frequency response analysis of periodically time varying circuits
Authors: Korotyeyev Igor 
Published: March 2018

Purpose
The purpose of this paper is to introduce a method for the analysis of steady-state processes in periodically time varying circuits. The method is based on a new definition of frequency responses for periodic time-varying circuits.

Design/methodology/approach
Processes in inverter circuits are often described by differential equations with periodically variable coefficients and forcing functions. To obtain a steady-state periodic solution, the expansion of differential equations into a domain of two independent variables of time is made. To obtain differential equations with constant coefficients the Lyapunov transformation is applied. The two-dimensional Laplace transform is used to find a steady-state solution. The steady-state solution is obtained in the form of the double Fourier series. The transfer function and frequency responses for the inverter circuit are introduced.

Findings
A set of frequency characteristics are defined. An example of a boost inverter is considered, and a set of frequency responses for voltage and current are presented. These responses show a resonance that is missed if the averaged state-space method is used.

Originality/value
A new definition of frequency responses is presented. On the basis of frequency responses, a modulation strategy and filters can be chosen to improve currents and voltages.
Wideband DOA estimation based on incoherent signal subspace method
Authors: Ahmad Zeeshan , Song Yaoliang , Du Qiang 
Published: March 2018

Purpose
Direction-of-arrival (DOA) estimation for wideband sources has attracted a growing interest in the recent decade because wideband sources are incorporated in many real-world applications such as communication systems, radar, sonar and acoustics. One way to estimate the DOAs of wideband signals is to decompose it into narrowband signals using discrete Fourier transform (DFT) and then apply well-established narrowband algorithms to each signal. Afterwards, results are averaged to yield the final DOAs. These techniques require scanning the full band of wideband sources, ultimately degrading the resolution and increasing complexity. This paper aims to propose a new DOA estimation methodology to solve these problems.

Design/methodology/approach
The new DOA estimation methodology is based on incoherent signal subspace method (ISSM). The proposed approach presents a criterion to select a single sub-band of the selected narrowband signals instead of scanning the whole signal spectrum. Then, the DOAs of wideband signals are estimated using the selected sub-band. Therefore, it is named as single sub-band (SSB)-ISSM.

Findings
The computational complexity of the proposed method is much lower than that of traditional DFT-based methods. The effectiveness and advantages of the proposed methodology are theoretically investigated, and computational complexity is also addressed.

Originality/value
To verify the theoretical analysis, computer simulations are implemented, and comparisons with other algorithms are made. The simulation results show that the proposed method achieves better performance and accurately estimates the DOAs of wideband sources.
Experimental evaluation of electric and magnetic properties of structural steel
Authors: Piccoli Phamella Reinert Tamanini , Cabral Sérgio Henrique Lopes , de Oliveira Luiz Fernando , Iaronka Odirlan , Harmel Diogo Fernando , Vieira João Paulo , Sapeli João Egídio 
Published: March 2018

Purpose
This paper aims to present the proposition of a new experimental method for obtaining very crucial data of the structural steel that is used in the tank of oil filled power transformers, namely, the volumetric losses and the magnetic permeability, both in function of the density of magnetic flux. Although these data are not usually available, they are fundamental for helping the transformer designer in avoiding the occurrence of hot spots in the transformer tank. The adoption of a conventional Epstein frame has restrictions because of the incompatibility between it and the samples of the steel.

Design/methodology/approach
The basis of the proposition is the same as that of the Epstein frame, with significant attention paid to the additional losses in the winding that creates the magnetic flux to the samples in the core. These losses can be significant and are created by the harmonics of current along the windings and are summed to the ohmic losses. For separating these winding losses from the magnetic losses, each sample is made as being the core of a toroidal 1:1 transformer. Thus, two tests with two identic of these toroidal transformers are necessary.

Findings
The proposed methodology is simple, because it is very similar to the classical tests of transformers (no-load and short-circuit tests). The process of separation of losses requires only a numerical fitting of curves for adjusting the winding losses as a function of the current amplitude, and the obtained results are coherent with the expected behavior of the magnetic losses and the magnetic permeability of a structural steel.

Research limitations/implications
The method gives very approximate results in comparison to those obtained using the Epstein frame. The influences of the temperature and/or of the skin effect have not been evaluated.

Practical implications
Practical, real and thus confident data of structural steel, such as the magnetic permeability and the volumetric losses (hysteresis and Foucault), become available for the transformer designer to take actions for not only reducing the tank losses but also for avoiding the occurrence of hot spots through computer simulation.

Originality/value
The proposition is very new, as it allows to test steel samples with a size that does not fit to a usual Epstein frame. It takes into account the real influence of harmonic of currents in the losses along the winding of a classical Epstein frame, which has not been so far mentioned. It allows obtaining data of structural steel that had not been considered important until now.
Network modelling of dry-type transformer cooling systems
Authors: Cremasco Andrea , Wu Wei , Blaszczyk Andreas , Cranganu-Cretu Bogdan 
Published: March 2018

Purpose
The application of dry-type transformers is growing in the market because the technology is non-flammable, safer and environmentally friendly. However, the unit dimensions are normally larger and material costs become higher, as no oil is present for dielectric insulation or cooling. At designing stage, a transformer thermal model used for predicting temperature rise is fundamental and the modelling of cooling system is particularly important. This paper aims to describe a thermal model used to compute dry transformers with different cooling system configurations.

Design/methodology/approach
The paper introduces a fast-calculating thermal and pressure network model for dry-transformer cooling systems, preliminarily verified by analytical methods and advanced CFD simulations, and finally validated with experimental results.

Findings
This paper provides an overview of the network model of dry-transformer cooling system, describing its topology and its main variants including natural or forced ventilation, with or without cooling duct in the core, enclosure with roof and floor ventilation openings and air barriers. Finally, it presents a formulation for the new heat exchanger element.

Originality/value
The network approach presented in this paper allows to model efficiently the cooling system of dry-type transformers. This model is based on physical principles rather than empirical assessments that are valid only for specific transformer technologies. In comparison with CFD simulation approach, the network model runs much faster and the accuracies still fall in acceptable range; therefore, one is able to utilize this method in optimization procedures included in transformer design systems.
Awareness of intellectual capital among bank executives in India: a survey
Authors: Joshi Mahesh , Kansal Monika , Sharma Sharad 
Published: March 2018

Purpose
This paper aims to explore the awareness of terminology related to intellectual capital (IC) among executives of Indian banks and the sources in which they mostly find IC-related terminology. The paper also explores relative and specific contributions of each selected source of information in creating IC awareness among bank executives in India and determines difference among the executives from the public and private sector.

Design/methodology/approach
This research paper follows a survey-based approach to capture the perceptions of Indian bank managers working middle and top management across different banks. Regression analysis and ANOVA were applied to data from 166 responses.

Findings
The study finds that IC awareness among Indian banking executives is reasonably high and is equally spread across the three sub-categories of capital (external capital, human capital and internal capital), though the relative awareness of external capital is on the higher side. However, the sources of awareness of IC terminology differ among executives from the public- and private-sector banks.

Research limitations/implications
The sample was limited to middle and top managers in the Indian banking industry and suffers from the usual limitations of survey-based research such as the design of the survey instrument and the personal biases of the respondents. Some limitations may also have arisen because of the definitions of IC elements adopted by this study.

Originality/value
This research adds a new dimension to the IC research by exploring the practical application and awareness of IC that deviates from traditional annual report-based disclosure and valuation studies. No existing literature has examined the survey-based awareness study, particularly on the banking industry. This paper provides a foundation for future studies that examine the operational awareness and application of IC in the service industries.
Teachers’ perspectives on handwriting and collaborative intervention for children with Autistic Spectrum Disorder
Authors: McNamee Therese , Patton Sandra 
Published: March 2018

Purpose
This study aims to investigate teacher perspectives on teaching handwriting to children with autistic spectrum disorder (ASD) and collaboration with occupational therapists.

Design/methodology/approach
A descriptive design was applied. Purpose-designed surveys were distributed to teachers of children with ASD (aged 4-12 years) in the Republic of Ireland. A response rate of 35 per cent (N = 75) was obtained, with 25 responses analysed using descriptive statistics of closed questions and content analysis of open-ended questions.

Findings
Of 139 children with ASD, 80 (58 per cent) were reported to have difficulties with handwriting. Teachers reported specific difficulties with pencil grasp, letter formation and task concept among the children with ASD. Fourteen (56 per cent, N = 25) respondents did not give handwriting as homework. Teachers valued occupational therapy advice, individualised programmes and ongoing consultation during implementation. Interest in occupational therapy education regarding handwriting was reported.

Practical implications
Occupational therapy collaboration to address handwriting difficulties for children with ASD should include involvement in teacher education, coordination of teacher–parent collaboration and the need for involvement in early intervention provision within an emergent literacy framework.

Originality/value
Handwriting development is challenging for children with ASD. There is limited information on teaching or teacher–occupational therapy collaborative practices to address handwriting difficulties of children with ASD.
“Collective violence” and honour in Finland: a survey for professionals
Authors: Lidman Satu , Hong Tuuli 
Published: March 2018

PurposeThe purpose of this paper is to report on how honour-related violence (HRV) is understood and managed by professionals in Finland, emphasising the need to consider collectivity as an influential factor. Therefore, this paper introduces the concept of “collective violence”. By investigating the level of awareness and recognition of these violence phenomena, this paper discusses both preventative and punitive measures that Finnish authorities are able to work with.Design/methodology/approachA total of 111 Finnish anti-violence professionals completed a survey that aimed to qualitatively investigate their perceptions of HRV and collectivity.FindingsThe findings of this study indicated that collective violence is generally poorly recognised among professionals in Finland. At present, both victim services and criminal justice system lack adequate structures to deal with issues of collective violence. These findings indicate that authorities need further education on HRV and collectivity, as well as debates on whether the criminal code should be amended to meet international requirements.Originality/valueAs this violence has been researched only sporadically in the Finnish context, this study provides new insight to under-researched area of honour-related and collective violence in Finland. These findings may assist other European countries dealing with similar issues as well as guiding preventative and punitive measures within the Finnish context.

Authors: Aribi Zakaria Ali , Alqatamin Rateb Mohammad , Arun Thankom 
Published: March 2018

Purpose
The purpose of this paper is to provide empirical evidence of the relationship between female representation on the board and forward-looking information disclosures (FLIDs).

Design/methodology/approach
The study uses the content analysis to analyze the narrative evidence from the annual financial reports of non-financial Jordanian companies listed on the Amman Stock Exchange. The final sample consists of 1,206 firm-year observations during the period 2008-2013.

Findings
The study provides evidence that gender diversity on boards positively affects the level of FLIDs. Further to this, the study reveals that family firms disclose more information than non-family firms.

Practical implications
Results of this study could be beneficial for a number of users of financial information such as, regulators, investors, auditors and lenders. The users might consider the findings of this study when they are using the company’s financial information. Consequently, users of this information could be better assisted to make right decisions.

Originality/value
This study contributes to the literature by identifying the role of gender on the level of FLID, particularly on family and non-family, a relatively little researched area.
