Purpose The purpose of this paper is to investigate the influences of fibre lengths and a given range of paper grammages on the fundamental properties of unprinted and printed papers by using mineral oil-based offset printing inks and also evaluate these results in terms of printing and tensile characteristics. Design/methodology/approach A design research approach has been based on the production of various laboratory handmade papers and their printing process with mineral oil-based offset printing inks. The analysis of mechanical and structural tests results of the unprinted and the printed papers have been evaluated. Findings This study is confirmed that the mineral oil-based offset printing inks can be easily applied to the surface of papers having different grammages and pulp contents. An increase was observed in the tensile index values of the papers with the printing process, and these increases were more evident (about 80%) particularly in low grammage papers having high short fibre content. Originality/value The originality of this work is based on understanding and comparing the effects of grammage and the effect of pulp contents (having long and short fibre) on tensile characteristics of printed and unprinted handsheets.

Purpose This paper aims to investigate the influences of fines and precipitated calcium carbonate (PCC) pigment and their contents on the fundamental properties of handsheets and also evaluate these results in terms of mechanical and chemical data. Design/methodology/approach A design research approach has been based on the production of various laboratory handmade papers. Any of the paper additives were not added to the paper web to compare the results of the effects of fines and PCC pigment in a literal way. For this purpose, the target grammages of handsheets and the production variables such as pulp consistency, temperature and other variables of formation, pressing and drying processes were kept constant and studied meticulously. Findings This study is confirmed that with the addition of fines to the pulp of the control handsheets, an increase of up to 125% has been observed in the tensile index values, while a decrease of up to 30% has been observed with the addition of PCC pigment as filler. The tensile results have been changed depending on the pulp content and hence chemical bonds formed in the paper web. These mechanical changes have been explained by correlating with the data of FT-IR spectrums. Especially, the variations have been seen at 950–1150 cm−1, which referring to C-OH and C-O-C stretching vibrations. Originality/value The originality of this work is based on understanding and comparing the effects of fines and the effect of PCC pigment as a paper filler on the structural and chemical characteristics of laboratory-made handsheets.

Purpose The purpose of this paper is to investigate the influences of coating colours and their contents on the fundamental properties of base papers and also evaluate these results in terms of mechanical and wood-free papers. Design/methodology/approach A design research approach has been based on the application of various coating colours and analysis of mechanical and optical tests results of the coated mechanical and wood-free base papers. Findings This study is confirmed that the coating colours can be easily applied to the surface of the papers. The experimental data have revealed that significant improvements exist in the values of tear resistance (strength), brightness and opacity of the mechanical base papers, especially by the application of the coating colours including kaolin pigment. The results show that mechanical papers can also be used in areas with high brightness expectations by applying coating colour. Originality/value The originality of this work is based on understanding and comparing the effects of applying similar coating formulations on mechanical and wood-free base papers.

In the Printing Industry, printing inks, varnishes, lacquers, moistening solutions and washing solvents (ethanol, methyl acetate, ethyl acetate, isopropanol, n-propanol, hexane, benzene, toluene, xylene, isopropyl acetate, propyl acetate, dimethyl ketone, glycols and glycol ethers) contain volatile organic compounds (VOCs) and air pollutants (HAPs). Especially solvent based inks used for flexo, gravure and screen printing, offset printing dampening solutions and cleaning solvents contain high concentration of VOC. These organic compounds evaporate during the production process or contribute to the photochemical reaction. VOCs and HAPs, together with sunlight and nitrogen oxides, cause photochemical smoke, air particles and ground level ozone emission in the atmosphere. The VOCs and heavy metals can lead to soil and even water pollution when left in landfill. The amount of solvent retained by flexo, gravure and screen-printed products is 3-4% of total ink solvent used. The solvent in the printed ink content, except for the one held by the printed material evaporates in its own environment after the printing process. Most of these solvents and organic compounds used in printing environment contain at least one carbon and hydrogen atom and have negative effects on health and environment.In this study, the environmental impacts and risks of inks and solvents used in the printing industry have been evaluated. Measures to be taken to reduce and manage these environmental effects and risks have been addressed and recommendations have been made.

Purpose The purpose of this paper is to explore through a project the feasibility of testing Carpo’s preposition of the second digital turn. It further argues that if media architecture could progress into a new digital design that makes use of large amount of data, the ability of computers to filter through these data and the computers capacity to generate a physical output based on data enabled through a “digital trial and error” process and “age-old problem” in media architecture design could be addressed—in the following called Master/Slave relationship. Its breakdown is then consequently a result of applying second digital turn thinking to media architecture. Design/methodology/approach The paper outlines two aspects to discuss the design of a media architecture installation: first, a qualitative method using the e-mail trails between the research team developing the installation to uncover trends in thought and opinion to identify if a Master/Slave outcome could have been avoided, thus it has the second digital turn thinking provided a “neutral judge”. Second, a design research approach where the designed outcome of the installation is discussed and evaluated. The scope of the chapter only allows for a short overview of the design process as such. Findings The authors could demonstrate that the design approach using second digital turn principles had overcoming the problem of a Master/Slave relationship in media architecture. Further, media architecture provides to the second digital turn, the advantage of providing input variables is of a technical nature and a clear set of objective relationships between the technical variables and constraints. Hence, it is easier to design x-number of design options. Media architecture also has advantage that the aesthetic judgement is potentially easier (which option to choose), as the primary function of most media façades lies in communicating dynamic text, graphic or images. Originality/value The paper understands its value in opening up and contributing to the question on how to judge objectiles. When designers are now in a position to develop computer programs that can design objects how does one judge which is the best object out of all the potential options? The paper argues that if the aesthetic quality of the outcome is understood a later judgement might be easier.

Purpose The purpose of this study is to identify the print effects produced on selected fabrics due to the adaptation of styrofoam, plastic net and wood as stamp blocks for printing. Design/methodology/approach The art-based experimental research approach was used to produce and identify the art (prints) produced by stamp blocks on different fabrics using water-soluble print paste. Findings They stamp block surfaces used in the block printing process produced interesting effects or prints that are uniquely associated with each other. Fabrics such as silver and satin produced shinny print effects coupled with a tough hand or feel as compared to a paperish hand produced on the surfaces of cotton-polyester blend and linen fabrics. The addition of white glue to the paste produced a smooth and embossed-like print effect on fabrics like mercerised cotton and linen. Further results were captured to indicate the hand of these fabrics after printing due to the change in viscosity of the print paste. Originality/value The use of calabash and wood surfaces as stamp blocks used in Ghana and the rest of the world is common for printing patterns on fabrics. This study essentially reveals the possibility of using different surfaces for stamp blocks which produce aesthetically pleasing print effects. This when adopted by craftsmen and students would widen the teaching and creative scope in block printing and further produce viable prints for the market using available materials in the environment. These activities would promote and maintain the philosophy of block printing even in the era of advance printing technologies.

Real World Situation

Purpose – The purpose of this paper is to explore the effectiveness of action design research (ADR), a combination of action research and design science research, when conducting research where both practical relevance and academic rigor are required. Design/methodology/approach – This paper presents ADR in action in order to motivate its use when investigating real-world organisational concerns requiring practical solutions, whilst also fulfilling academic requirements. Findings – When research methodology aligns to research objectives, the resulting synchronicity can elevate the outcome considerably. From this study, which attempts to address concerns of informing practice, as well as advancing theory, ADR appears to be an extremely effective research tool. Research limitations/implications – The study is limited to a single organisation and it would not be possible to make statistical generalisations. It is hoped, however, that the findings can be generalised to a theory that can be used in a similar setting. It would be valuable to discover whether other studies using ADR also find such effective alignment between relevance and rigour. Practical implications – The research involves an intervention in the finance course offerings for staff training in the workplace. The detailed description of each of the seven ADR stages could prove useful for other researchers contemplating using ADR. The paper offers an example of ADR in practice. Originality/value – This paper outlines the suitability and advantages of adopting an ADR approach, where the goal is to meet the challenge of implementing a solution in a real-world situation, whilst also adding to academic theory and knowledge.

Purpose While the current knowledge in the field of educational leadership and management (EDLM) has been primarily based on research produced in English-speaking Western societies, there have been significant efforts by other societies to contribute to the knowledge production, especially during the past decade. The purpose of this paper is to identify the contribution of Turkey to the international EDLM literature by investigating the topical focus, conceptual frameworks and research designs of papers published by EDLM scholars from Turkey. Design/methodology/approach Descriptive content analysis method was employed to examine 315 empirical, review, conceptual and commentary papers published by Turkish scholars in core educational administration and Web of Science journals. The time period of the review left open-ended. However, in practical terms, it begins in the year 1994 when the first article from Turkey was published in any of the selected sources and ends at the end of 2018. Information relevant to the research was extracted from each article and was coded to facilitate quantitative analysis. Using Excel software, descriptive statistics including frequencies and percentages were provided for each research question. Findings Results show that Turkish EDLM scholars mostly rely on survey based quantitative research approach, employing advanced statistical techniques in the analysis of the data. However, mixed method and qualitative studies are relatively less common. Organizational behavior, school leadership and emotions stand out as most frequently used topics, while Turkish scholars are not interested in analyzing the educational outcomes such as student achievement and school improvement. Consistent with the findings related to topical foci, a large number of those who were interested in correlational studies examined the relationship between leadership roles and organizational behaviors. Research limitations/implications The data set only included journal articles and excluded conference proceedings, books and theses/dissertations. Nevertheless, the authors believe this review adds significantly to previous reviews of local EDLM journals conducted by Turkish scholars. The authors concluded that the Turkish scholars should direct their future research to exploring and better understanding the practices of Turkish principals in schools by: diversifying their research topics; incorporating more qualitative and mixed-method designs; and taking into account specific features of the culture and educational system in Turkey. Practical implications Based on the current higher education context, reducing scholars’ teaching load, diversifying research funding opportunities, and modifying access to tenure tracks seem necessary interventions to support EDLM research with strong ties to practice and to the sociocultural context. In addition, policy changes aiming professionalization of administrative positions and establishing some forms of formal training for school principalship are needed. Such changes can help transfer the knowledge produced by the Turkish EDLM researchers to the practice and provide solutions to problems related to school administration. Originality/value This paper will add to recent effort to identify how a developing nation outside Western perspective approaches the field, and contributes to the global knowledge base.

PurposeThe purpose of this paper is to expand the theory on multistory cultural change by showing how a dominant narrative on construction safety dynamically interrelates and is contested on multiple intertextual levels in an organizational field of organizations contributing to the recovery of houses in an earthquake region.Design/methodology/approachAn ethnoventionist research approach was adopted in which interpretation of data to find narratives and designing interventions went hand-in-hand.FindingsWe found four distinctive composite narratives besides the dominant narrative to which five actors refer in their accounts, thereby contributing to three types of story patterns. These narratives disclose the taken-for-granted ideas and beliefs that characterize the challenge of changing organizational culture. One intervention, which intended multiple stories to touch the surface, was highlighted as a multistory intervention.Research limitations/implicationsFurther research could extend the knowledge on other change interventions that contribute to multistory cultural change processes.Originality/valueAdopting an ethnoventionist approach to provide deep insights on an unfolding cultural change process for both scholars and practitioners.

Audit Fee

Purpose – The authors aim to exploit a natural experiment in which voluntary replace mandatory joint audits for Danish listed companies and analyse audit fee implications of using one or two audit firms. Design/methodology/approach – Regression analysis is used. The authors apply both a core audit fee determinants model and an audit fee change model and include interaction terms. Findings – The authors find short-term fee reductions in companies switching to single audits, but only where the former joint audit contained a dominant auditor. The authors argue that in this situation bargaining power is more with the auditors than in an equally shared joint audit, and that the auditors' incentives to offer an initial fee discount are bigger. Research limitations/implications – The number of observations is constrained by the small Danish capital market. Future research could take a more qualitative research approach, to examine whether the use of a single audit firm rather than two has an effect on audit quality. The area calls for further theory development covering audit fee and audit quality in joint audit settings. Practical implications – Companies should consider their relationship with their auditors before deciding to switch to single auditors. Fee discounts do not seem to reflect long-lasting efficiency gains on the part of the audit firm. Originality/value – Denmark is the first country to leave a mandatory joint audit system, so this is the first time that it is possible to study fee effects related to this.

Purpose The purpose of this paper is to examine how internship value is manifested in the context of a business school. The authors have examined the internship experience in terms of experiential learning and employability. Specifically, the authors investigate the factors that determine internship at four phases: design, conduct, evaluation and feedback. Design/methodology/approach The authors have applied a mixed method approach. In all, 110 students of a busines school were first surveyed on their expectation, motivation and level of preparation through a self-administered questionnaire before internship. Based on the survey result, eight of these students were interviewed in details about internship expectations from industry, the selection process for internship, communications or exchanges between intern and companies prior to internship and perceived industry expectation from interns. At the next phase, authors used a qualitative research approach by conducting semi-structured, in-depth interviews with 14 interns and their mentors after internship period. They were interviewed on design, conduct, evaluation and feedback process of the internship. Interviews tried capture what kind of leader-member exchange led to satisfactory internship experience and outcome from view of both inter and mentor. Findings The authors find that at various stages of internship program quality of mentor – intern exchanges (as defined by leadership exchange theory), and task characteristics as indicated by autonomy, task variety, task significance and performance feedback determine intern’s performance. An intern’s performance is antecedent to an intern’s and a mentor’s satisfaction and overall internship value. The authors also found that intrinsic capability of intern such as critical thinking ability and learning orientation result in enhanced value of internship experience. The proposed models, postulate that at designing stage, lower the level of communication from employers, higher the feeling of ambiguity and lower the perceived internship value in terms of experiential learning and perceived employability. Feeling of ambiguity is moderated by existence of prior work experience of interns. At conduction stage, mentor-intern exchange is directly related to flexibility in structure of the program and inversely related to dependency on peer learning. Mentor-intern exchange also related to mentor and intern’s learning value. However, the learning value is moderated by learning orientation of the intern. Originality/value The authors have tried the summer internship experience from the perspective of interns and mentors. This is the uniqueness of the research.
