Abstract

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.

Abstract

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.

Abstract

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.

Abstract

In this chapter, the authors studied cognitive biases such as certainty effect, isolating effect, and overconfidence effect in the Turkish version of “Who Wants to be a Millionaire” TV show. The research was carried out by watching the show during different dates between September 2013 and April 2015 and filling in a questionnaire, which consists of 25 questions. A total of 408 contestants were observed and evidence was found for both certainty and isolation effects.

Abstract

The study seeks to understand the experiences and perceptions of the university youth regarding the democratic atmosphere of a public university located in Turkey. To this end, the objective of this research is twofold: (1) to investigate university students’ level of civic engagement regarding student activism, exercising rights, and interest in politics; and (2) to explore students’ perception of their university environment regarding the promotion of tolerance, respect for ideas, and participation in decision-making. This study was carried out at a public university located in the middle of Turkey. A mixed-method approach was employed, including both qualitative and quantitative data. A total of 332 undergraduate students participated in the quantitative part while 14 undergraduate students were interviewed in the qualitative part of the study. In quantitative data collection, two self-developed scales were used: Civic Engagement Scale and Perceptions of Democratic University Environment Scale. The results of the data analysis indicated that students’ overall civic engagement level was below the average level. In particular, the level of students’ activism was significantly lower than that of students’ interest in politics and exercising rights, respectively. In addition, the level of students’ interest in politics was significantly lower than that of students’ exercising rights. With respect to the students’ perception of democratic university environment, the data revealed that students’ overall perception of the university environment was slightly above average level. Specifically, the students’ perception of university environment regarding respect for ideas was significantly higher than that of university environment regarding participation in decision-making.

Abstract

Along with accounting scandals in the past, academics, researchers, and legislators have focused on fraud. The purpose of this study is to examine postgraduate and doctoral studies, articles, and books about forensic accounting and fraud audit published between the years 2008 and 2018 in Turkey. For this purpose, a total of 96 studies have been examined and 35 of these are master’s theses, 10 of them are PhD theses, 45 of them are articles, and six of them are books. These studies were presented in tables as classified. The studies examined in our research are summarized as year they were published, the author, and the scope of the topic and in terms of results. The conclusions of this study can be summarized as follows: (a) the majority of thesis published about forensic accounting and fraud audit are in 2011 and following years. In addition, most of the theses are focused on forensic accounting review rather than fraud audit. (b) Results in the articles reviewed are in the same direction with theses. (c) There are very few books about fraud audit and forensic accounting. One of them is related to fraud audit, while the rest of them are related to forensic accounting and forensic accounting profession. We suggest extending the scope of the study and making to other countries.

Abstract

Purpose

The purpose of this paper is to explore the complexity of developing into an international institution from the perspective of higher education leaders through the case study of one institution engaged in institutional transformation.

Design/methodology/approach

This study employs the qualitative approach and involves in-depth interviews with key institutional managers.

Findings

Findings suggest internationalization is a dynamic change process that goes beyond the rational and predictive elements of internationalization and cannot be confined to the rational planning and grand plans solely at institutional level. Reciprocal influence of different levels of analysis – institution, society and the nation – needs to be acknowledged and internationalization efforts need to go beyond the confines of the institution and extend into the society and the nation as a whole.

Originality/value

Internationalization of higher education has been widely examined, but the reciprocal influence of different levels of analysis on the internationalization efforts of higher education institutions is thin to which this paper contributes.
