Abstract
Purpose
Access to related information is a key requirement for exploratory search. The purpose of this research is to understand where related information may be found and how it may be explored by users.
Design/methodology/approach
Earlier research provides sufficient evidence that web graph neighborhoods of returned search results may contain documents related to users' intended search topic. However, in the literature, no interface mechanisms have been presented to enable exploration of these neighborhoods by users. Based on a modified web graph, this paper proposes tools and methods for displaying and exploring the graph neighborhood of any selected item in the search results list. Important issues that arise when implementing such an exploration model are discussed and utility of the proposed system is evaluated with user experiments.
Findings
In user experiments first, information related to intended search topic was often found in the web neighborhood of search results; second, exploring these graph neighborhoods with the proposed tools improved users' ability to reach the information they sought.
Research limitations/implications
The test participants are computer science graduate students. Their skills may not be representative of the broad user population.
Originality/value
The lessons learned from this research point to a potentially fruitful direction for designing new search engine interfaces that support exploratory search.

Abstract
The article examines the Turkish beer market and the experience of Turkey's most successful brewer, Efes Pilsen, within that market. Using the product life cycle, it describes the development of the market and Efes' competitive strategies. It assesses the impact of the government's 1984 decision to reclassify beer as an alcoholic beverage. Finally, it identifies several lessons for marketing non‐necessary consumer goods such as beer in developing countries.

Abstract
Learning outcomes
The key learning from this case study include the following: first, there are various leadership types that leaders can exhibit, such as servant leadership and transformational leadership, and an individual’s leadership style can be evaluated by analysing his/her traits and behaviours. Second, decision-making is much more critical for leaders than for anyone else, and there are different approaches, such as rational and intuitive decision-making, that leaders can apply when making a decision. Third, in male-dominated work environments such as the sports sector, female executives should carefully weigh the risks and opportunities of leadership positions while being promoted.
Case overview/synopsis
The UPS Sports and Culture Club was founded in 2003 by Haluk Ündeğer in Zeytinburnu district, one of the most dangerous neighbourhoods in Istanbul that had a bad reputation for being high on crime and drugs. The club’s main goal was to train children from disadvantaged groups to develop a career in sports. Shortly after the club’s founding, Semra Demirer, a physical education teacher who had devoted her life to children’s physical, cultural and personal development, crossed paths with the UPS Club. In 2004, Demirer started to work at the UPS Sports and Culture Club as the general coordinator. She played an important role in the growth and development of many children over the years and helped raise very talented athletes such as Simge Aköz. In 2020, on the heels of financial and administrative difficulties, the club was at the risk of being shut down. Hence, Demirer grappled with the decision of whether to share this information with the employees and players in the club. She deeply considered how she could overcome the conflict between transparency and confidentiality she was experiencing.

Abstract
Purpose
To study the concept of honor in Turkish everyday life discourses. Many surveys have focused on namus, thus referring to honor killings, the mechanism of violence perpetrated against women. The reason given for such killings, often seen as barbaric and the result of criminal urges, is that some men feel compelled to restore what they see as family honor, soiled by the actions of their female relatives. However, these studies avoid another key aspect of honor: namely the plurality of its meanings as honor in Turkey may also be translated both as şeref and onur.
Design/methodology/approach
To begin to understand honor in all its forms, I conducted interviews with 100 Turkish men and women ages 20–27, all university students or graduates, from the Istanbul area. I also consulted the current official and Ottoman dictionaries to understand the history of word use.
Findings
Among the young adults interviewed “honor-virtue” (i.e., namus) is a debated topic. It may be analyzed at both theoretical and geographic levels and has the connotations of otherness and non-modernity. Namus co-exists with şeref (citizen honor) and onur (dignity).
Social implications
Redefining the terms of honor could temper tensions between local/global, urban/countryside, modern/traditional, woman/man, and invisible frontier between namus and şeref worldviews. Advocating şeref and focusing on a broader definition of namus may encourage individuals to find their places in society. By focusing on national moral values, any individual in the country may participate in keeping the social order regardless of gender, age, or geographic location.

Abstract
Purpose
Borsa Istanbul 100 Index, known as BIST100, is the main indicator to measure the performance of the 100 highest stocks publicly traded in Borsa Istanbul concerning market and trading volume. BIST 100 index prediction is a popular research domain for its complex data structure caused by stock price, commodity, interest rate and exchange rate effects. The study proposed hybrid models using both Genetic, Particle Swarm Optimization, Harmony Search and Greedy algorithms from metaheuristic algorithms approach for dimension reduction, and MARS for prediction.
Design/methodology/approach
This paper aims to model in the simplest way through metaheuristic algorithms hybridized with the MARS model the effects of stock, commodity, interest and exchange rate variables on BIST 100 during the Covid-19 pandemic period (in the process of closing) between January 2020 and June 2021.
Findings
The most suitable hybrid model was chosen as PSO & MARS by calculating the RMSE, MSE, GCV, MAE, MAD, MAPE and R2 measurements of training, test and overall dataset to check every model's efficiency. Empirical results demonstrated that the proposed PSO & MARS hybrid modeling procedure gave results both as good as the MARS model and a simpler and non-complex model structure.
Originality/value
Using metaheuristic algorithms as a supporting tool for variable selection can help to identify important independent variables and contribute to the establishment of more non-complex models.ing, test and overall dataset to check every model's efficiency.

Abstract
Purpose
Does a highly standardized international advertising campaign enhance destination image? Drawing evidence from Turkey's Home Global Image Campaign, the authors investigate this fundamental question. This would help the authors to understand whether there are significant differences in cognitive and affective image among tourist groups in Europe in a destination where there is a highly standardized international advertising campaign.
Design/methodology/approach
Data collected from British, German, French and Italian tourists through the official Twitter account of the Turkish Ministry of Culture and Tourism (TMCT) were used to carry out the quantitative analysis. Analysis of variance test was performed to assess the differences in nationalities. The Scheffe test was also applied as a post hoc comparison.
Findings
Cognitive image attributes such as “good value for money,” “good climate,” “interesting and friendly people,” “beautiful scenery and natural attractions,” “interesting cultural attractions,” “appealing local food (cuisine)” and “hygiene and cleanliness” are found to be less favorable in the perceptions of French tourists than those of British, German and Italian tourists. British, German and Italian tourists perceive Turkey as a more pleasant destination than French tourists. Overall, the findings suggest that a highly standardized international advertising campaign fails to boost the destination image for all nationalities.
Practical implications
The TMCT officials should use the adaptation strategy in international advertising campaigns since the findings denote that the “one-size-fits all” approach is problematic. The TMCT should support and promote environmental sustainability efforts and green hotel practices to attract more tourists and use them in different communication channels.
Originality/value
Assessment of affective and cognitive destination images (differences) is still an unresolved issue in the destination management and marketing literature. It seems that there is no empirical study investigating the cognitive and affective image attributes of a destination based on standardization versus adaptation approaches. This paper makes a contribution to the current literature by demonstrating that using the same image campaign in different markets is a practice that fails to achieve the intended goals.
