Abstract

Purpose

Lithium-polymer batteries have common usage in aviation industry especially unmanned aerial vehicles (UAV). Overheating is a serious problem in lithium-polymer batteries. Various cooling methods are performed to keep lithium-polymer batteries in the desired temperature range. The purpose of this paper is to examine pouch type lithium-polymer battery with plate fins by using particle image velocimetry (PIV) and computational fluid dynamics (CFD) for UAV.

Design/methodology/approach

Battery models were produced with a 3D printer. The upper surfaces of fabricated battery models were covered with plate fins with different fin heights and fin thicknesses. Velocities were obtained with PIV and CFD. Temperature dissipations were acquired with numerical simulations.

Findings

At the end of the study, the second battery model gave the lowest temperature values among the battery models. Temperature values of the seventh battery model were the highest temperatures. Fin cooling reduced the maximum cell temperatures noticeably. Numerical simulations agreed with PIV measurements well.

Practical implications

This paper takes into account two essential tools such as PIV and CFD, for fluid mechanics, which are significant in the aviation industry and engineering life.

Originality/value

The originality of this paper depends on investigation of both PIV and CFD for UAV and developing a cooling method that can be feasible for landing and take-off phases for UAV.

Abstract

Marketing has changed rapidly over the last four decades. Not a core discipline itself, its applications have become more complicated, more dynamic and more customised than ever before. Achieving differentiation in product is as difficult as reaching an aurora. Instead, marketers use communication tools to draw attention and increase awareness. But in the era of artificial intelligence, number of communication channels, competitors and lack of patience to read or listen to branded messages are not helping to reach targets. To keep the brands’ images clear and memorable, marketers need to create powerful content to deliver through any touchpoints. And that means INTEGRATION: ‘coordinating the company’s many communication channels to deliver a clear, consistent and compelling message about the organisation and its products’.

The dynamics of marketing communication mix can vary in different geographies. Being a developing country makes Turkey a fast mover but unstable. Although coping with these dynamics is not easy, it could be learnt. This chapter aims to help the reader find some useful information about Integrated Marketing Communication applications in the Turkish market.

Abstract

The EU harmonisation has created changes in the military's formal and informal influence in the directions of decreased formal and informal military influence in civilian politics. The EU reforms have created changes in the mindset of the citizens, by creating changes in the security culture of the citizens and in the civil-military related political culture. The desired level of alignment has not been reached. Therefore, the study examines the areas where further alignment is required. Moving from Rebecca L. Schiff's concordance theory, the article examines the relationship between the Turkish military, the civilian politics and the society before and after the EU harmonisation process. It examines the effects of the EU harmonisation process on the changes in the civil-military balance of power, and on the related security culture and political values. The analysis focuses on: (i) increased civilian control and consequent changes in the policy of accountability; (ii) transparency building in the defence sector; (iii) parliamentary oversight; and (iv) the change in the political culture related to the civil-military issues. It also investigates the extent the EU harmonisation has achieved in building democratic civil-military relations in order to align with the EU standards.

Abstract

Purpose

In the research, posts that tourists accommodated in the hotels during COVID-19 pandemic shared on TripAdvisor website about pandemic measures taken by establishments, have been analyzed within the context of value cocreation and codestruction. In addition, the study also aims to evaluate effects of posts by tourists on scores they give to the hotel, perceiving the hotel as safe, recommending and their intention to revisits.

Design/methodology/approach

In total, 1,119 reviews over TripAdvisor about 109 hotel establishments, which have safe hotel management certificate in Alanya, were examined, and they were coded in SPSS program with binary coding for positive and negative situations separately. For the analysis of associations between reviews about pandemic measures and the scores that tourists give to the hotel and their behavioral intentions, multiple linear regression analyses with dummy variables and Chi-square tests were utilized.

Findings

The study revealed that perceptions of tourists about pandemic measures have a significant effect on the scores they give to hotels, and this effect is asymmetrical in positive and negative situations. Negative perceptions cause much greater impact in terms of value codestruction than positive ones within the context of hotel evaluation and value cocreation. It has been observed that behavioral intentions of the tourist are formed and differentiated according to the characteristics of reviews.

Research limitations/implications

Apart from contributions to the theory and managerial implications, this study has some limitations. The biggest limitation of the research is that both value cocreation and codestruction are evaluated from the perspective of tourists. On the other hand, touristic service producers and suppliers are the one of the most important components in value cocreation and codestruction. Therefore, it is important to examine the value cocreation and codestruction initiatives of touristic service producers and suppliers in future research studies in order to offer a holistic perspective to the pandemic process. In this context, it is important to examine the pandemic measures implemented by food beverages, tour operators, travel agencies, car rentals, entertainment business and so on in future research. In addition, responsibilities of employees and customers, which are important components in the management of the pandemic process, should be evaluated in future research studies.

Practical implications

In the research, it has been established that tourists perform value cocreation and codestruction through their posts. In tourism establishments, formation of attitudes and behaviors of tourists for value creation on social communicational networks is possible through detection, amelioration and/or removal of factors causing value codestruction. Therefore, it is obvious that if hotel establishments concentrate on initiations about pandemic measures and compliance to measures, value cocreation attitudes and behaviors of tourists on social communicational networks will thus improve. Value cocreation attitudes and behaviors of tourists on social communicational networks are likely to have a function as an important strategical tool for supporting competitiveness and survival of the accommodation establishments.

Originality/value

The number of studies analyzing how value cocreation and codestruction occur on social communicational networks and the effects of these processes upon behavioral intentions of tourists is limited. With this aspect, this study is considered to fill this gap in tourism literature.

Abstract

Purpose

The purpose of this paper is to describe methodology and practices undertaken during a pilot study on food composition of Turkish traditional foods (TTF).

Design/methodology/approach

The pilot study was conducted under the European Food Information Resource Network (EuroFIR) Project for the systemic investigation of traditional foods. As a partner country of the EuroFIR, Turkey has selected five traditional foods, tarhana soup, yoğurtlu kebap (kebab with yoghurt), hamsi buğulama (anchovy stew), pastırma, and baklava. The traditional recipes of the selected foods were recorded by field studies. Nutritional composition of foods was determined by chemical analyses.

Findings

Information on the identification, sampling, sample handling, and analysis was collected for each of the selected foods. The food composition data were evaluated by using EuroFIR standards, and the recommended dietary allowances (RDA) for nutritents. Five TTF were meeting with various nutrient recommendations.

Originality/value

This pilot study on the systemic investigation of traditional foods would be an example for further traditional food studies in Turkey and would enable the generation of reliable, representative and sufficient quality data on TTF.

Abstract

Purpose

This paper aims to elaborate on the characteristics of vernacular architecture, particularly the architecture of the Turkish eastern Black Sea region, through a case study in the area; and to attract the attention of architects and researchers on the unique characters of the region. Another aim of the paper is to examine the contribution of vernacular architecture to sustainability through its design methods and principles, which have been developed throughout centuries.

Design/methodology/approach

This paper presents a single case study on the architecture of the Turkish eastern Black Sea region through 14 unique samples from Senoz (Büyükdere) Valley. The case study is preceded by theoretical research on vernacular architecture, its characteristics and its contribution to sustainable architecture.

Findings

The case study carried out in the Senoz Valley revealed that the region's vernacular architecture is still living. However, it has lost its importance in the past. Outcomes of the case study indicate that the unique character of the architecture in the valley needs to be protected and sustained, so that future generations can also benefit from its special design features.

Originality/value

Senoz Valley is a settlement located near the city of Rize in the eastern Black Sea region of Turkey. Vernacular architecture reflects the characteristics of the region and contains unique features in construction and planning. According to these special features, the architecture of Senoz valley deserves a place in the literature of vernacular architecture.
