Abstract

Purpose

This study aims to investigate the effects of open innovation (OI) and big data analytics (BDA) on reflective knowledge exchange (RKE) within the context of complex collaborative networks. Specifically, it considers the relationships between sourcing knowledge from an external environment, transferring knowledge to an external environment and adopting solutions that are useful to appropriate returns from innovation.

Design/methodology/approach

This study analyzes the connection between the number of patent applications and the amount of OI, as well as the association between the number of patent applications and the use of BDA. Data from firms in the 27 European Union countries were retrieved from the Eurostat database for the period 2014–2019 and were investigated using an ordinary least squares regression analysis.

Findings

Because of its twofold lens based on both knowledge management and OI, this study sheds light on OI collaboration modes and highlights the crucial role they could play in innovation. In particular, the results suggest that OI collaboration modes have a strong effect on innovation performance, stimulating the search for RKE.

Originality/value

This study furthers a deeper understanding of RKE, which is shown to be an important mechanism that incentivizes firms to increase their efforts in the innovation process. Further, RKE supports firms in taking full advantage of the innovative knowledge they generate within their inter-organizational network.

Abstract

The purpose of this study was to investigate Turkish pre-service teachers’ beliefs about social studies in order to expand upon a debate that has been ongoing for the last few decades. While there always have been various definition since the inception of the field, to date, no single, official definition has been agreed upon among social studies educators. The study indicated that there are a wide variety of beliefs regarding social studies exist among Turkish pre-service teachers. The vast majority of the participants characterized social studies is an integrated field of study, although what they included as tenets of this field varied widely. The majority of the participants cited either “preparing informed citizens” or “improving communication skills” as the sole purpose of social studies.

Abstract

The aim of this qualitative study was to determine what makes school principals successful. The study obtained data through interviews, both face-to-face and via e-mail correspondence. Content analysis provides the framework for analyzing the data. The data revealed that successful school principals have three different, but interrelated competencies, which are personal, administrative, and leadership competencies. The study also indicates that those successful principals gave priority to human relations, they see the school as their home where principals created a warm atmosphere, communicated effectively with all stakeholders, committed themselves to their schools, managed schools in a democratic way, solved problems on time and effectively.

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 study is to determine and compare the total and per passenger HC, CO, NOx and CO2 emissions from aircraft landing and takeoff (LTO) cycle before and during the COVID-19 pandemic. In addition, it is aimed to determine the global warming potential (GWP), environmental impacts (EIs) and enviroeconomic cost (eco-cost) of these emissions in total and per passenger.

Design/methodology/approach

Analyses were carried out with the help of the International Civil Aviation Organization’s Engine Emission Databank, using real flight data recorded by the airport authority.

Findings

During the COVID-19 pandemic, total pollutant emissions (HC, CO, NOx and CO2) decreased between 23.7% and 30.8% compared with the pre-pandemic period. In addition, per passenger pollutant emissions increased during the pandemic. Compared with the pre-pandemic period, GWP, EI and eco-cost values decreased by 24.1%, 23.89% and 23.93%, respectively, in the pandemic. However, the per passenger GWP, EI and eco-cost values increased by about 10% compared with the pre-pandemic period.

Practical implications

This study reveals the effects of COVID-19 in terms of EIs and environmental costs caused by aircraft in the LTO cycle.

Originality/value

The originality of this study is to calculate the pollutant emissions caused by aircraft in the LTO cycle with real flight data and to reveal the effects of the COVID-19 pandemic. The novelty of this study is the determination and comparison of total and per passenger pollutant emissions, GWP, EI and eco-cost before and during the pandemic.

Abstract

Since 2004, Turkish cinema has been witnessing an emergence of horror genre, now flooded with stories of possession by malevolent jinn, as transgressive, volatile figures of abjection. These female-centred narratives rely both on Islamic cosmology and myths and folktales of pre-Islamic Anatolian oral culture. The chapter will first explore the reasons horror has been neglected in the century-long history of cinema in Turkey and move on to highlight the socio-economic, cultural, and political contexts that were catalysts for the horror genre’s emergence. Then, the chapter will discuss the codes and conventions of the genre and explore the unique place of Alper Mestçi’s 2007 film Haunted (Musallat), among its contemporaries in terms of the ways in which the film challenges these established codes and conventions. In analysing Haunted, the chapter will use the theoretical framework of Barbara Creed, Carol J. Clover and Julia Kristeva to discuss the monstrous-feminine and masculinity as abjection.

Abstract

Purpose

Two major earthquakes which struck Northwestern Turkey in 1999 exposed rampant corruption involving construction and zoning code violations. The government’s relief efforts were tainted by corruption as well, and exhibited a great deal of incompetence. How voters responded to these in the next election held in 2002 is investigated. The fact that different group of parties were responsible for the construction of the shoddy buildings, and for the corruption and mismanagement related to relief, provided us with a unique opportunity to determine whether and how the electorate punished the culprits for each of these. The purpose of this paper is to shed light also on the new party system which emerged in Turkey after 2002.

Design/methodology/approach

Vote equations are estimated for the seven major political parties. These are fitted to cross-provincial data individually, using ordinary least squares and robust regression methods, and as a system, using seemingly unrelated regressions procedures. The same picture emerges from each of these methods.

Findings

Not just those ruling at the time of the earthquakes, but also other parties which were in power when the substandard buildings, were built were held accountable by the electorate. Furthermore, the Turkish voters appear to have allocated the blame rationally, taking into consideration the division of labor in the central government, and the relative influences the parties had on local administrations. Reaction of the voters to government incompetence and corruption was one of the factors which resulted in the emergence of a new party system. In 2002, the AKP, established only a year before, captured almost all of the far-right Islamist, about half of the far-right nationalist, and more than half of the center-right votes in 2002.

Originality/value

Corruption usually makes little difference in the fortunes of politicians. Some recent studies suggest that it takes more than just exposure of corruption to get the voters to react. Politicians pay a significant price only when the corruption touches all political parties across the board, is not accompanied by good governance, and competent non-corrupt alternatives are available. The results provide support for this assertion from the natural experiment that has taken place in Turkey.

Abstract

Purpose

The purpose of this paper is to focus on the removal of hexavalent chromium [Cr(VI)] from wastewater by using activated carbon-supported Fe catalysts derived from walnut shell prepared using a wetness impregnation process. The different conditions of preparation such as impregnation rate and calcination conditions (temperature and time) were optimized to determine their effects on the catalyst’s characteristics.

Design/methodology/approach

The catalyst samples were characterized using thermogravimetric analysis, scanning electron microscopy and Fourier transform infrared spectroscopy. The adsorption of Cr(VI) by using using activated carbon supported Fe catalysts derived from walnut shell as an adsorbent and catalyst was investigated under different adsorption conditions. The parameters studied were contact time, adsorbent dose, solution pH and initial concentrations.

Findings

Results showed that higher adsorption capacity and rapid kinetics were obtained when the activated walnut shell was impregnated with Fe at 5 per cent and calcined under N2 flow at 400°C for 2 h. The adsorption isotherms data were analyzed with Langmuir and Freundlich models. The better fit is obtained with the Langmuir model with a maximum adsorption capacity of 29.67 mg/g for Cr(VI) on Fe5-AWS at pH 2.0.

Originality/value

A comparison of two kinetic models shows that the adsorption isotherms system is better described by the pseudo-first-order kinetic model.
