Abstract
Purpose
Today, e-government (electronic government) applications have extended to the frontiers of health-care delivery. E-Nabız contains personal health records of health services received, whether public or private. The use of the application by patients and physicians has provided efficiency and cost advantages. The success of e-Nabız depends on the level of technology acceptance of health-care service providers and recipients. While there is a large research literature on the technology acceptance of service recipients in health-care services, there is a limited number of studies on physicians providing services. This study aims to determine the level of influence of trust and privacy variables in addition to performance expectancy, effort expectancy, social influence and facilitating factors in the unified theory of acceptance and use of technology (UTAUT) model on the intention and behavior of using e-Nabız application.
Design/methodology/approach
The population of the study consisted of general practitioners and specialist physicians actively working in any health facility in Turkey. Data were collected cross-sectionally from 236 physicians on a voluntary basis through a questionnaire. The response rate of data collection was calculated as 47.20%. Data were collected cross-sectionally from 236 physicians through a questionnaire. Descriptive statistics, correlation analysis and structural equation modeling were used to analyze the data.
Findings
The study found that performance expectancy, effort expectancy, trust and perceived privacy had a significant effect on physicians’ behavioral intentions to adopt the e-Nabız system. In addition, facilitating conditions and behavioral intention were determinants of usage behavior (p < 0.05). However, no significant relationship was found between social influence and behavioral intention (p > 0.05).
Originality/value
This study confirms that the UTAUT model provides an appropriate framework for predicting factors influencing physicians’ behaviors and intention to use e-Nabız. In addition, the empirical findings show that trust and perceived privacy, which are additionally considered in the model, are also influential.

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
The central goal of this research is to understand the effects of organizational culture and organizational resilience over the riskiness versus non-riskiness categorization of subcontractors. The paper aims to discuss these issues.
Design/methodology/approach
This study utilizes multiple sources of data collected in two different time setting. At time one, data were collected from the subcontractors (n=50) of a leading services providing company in Turkey. In order to validate these findings, second wave of data collection was followed one year later. This time, the data were collected from the subcontractors (n=59) of another services providing company in Turkey. Cluster approach was applied.
Findings
Results from the cluster analyses revealed interesting insights. Subcontractors that were characterized by high-performance orientation, high uncertainty avoidance and high future orientation were categorized as non-risky. Therefore, the hypotheses found support. Furthermore, in terms of the organizational resilience dimensions, subcontractors having high structural reliance, organizational capability and processual continuity were also categorized as non-risky. The validation study carried out with different subcontractors also revealed the same patterns of findings.
Research limitations/implications
This study revealed that organizational culture and organizational resilience carry critical implications during the subcontractor selection process. Focal companies that seek to expand their work with subcontractors should seek cultural fit and resilience.
Originality/value
This study is the first study to examine the effects of organizational culture and organizational resilience over subcontractor riskiness in the same framework. Furthermore, data were collected from different sources, in two different times and using different approaches.

Abstract
Energy use occupies an important place among the service activities offered to tourists that guide the tourism industry. The realization of basic needs such as heating, cooling, ventilation, lighting and decontamination in these enterprises are among the important factors that directly affect energy use. In order to obtain the energy needed for the sustainability of services at a more affordable cost, renewable energy sources should be put into operation. In this direction, it makes it more advantageous for businesses in the tourism sector to invest by turning to renewable energy sources in order to maintain their activities more economically. In this context, the main purpose of the study carried out in this part of the book is to reveal the latest developments in the field of evaluation of renewable energy sources in tourism enterprises. Bibliometric analysis was carried out by using the Web of Science (WoS) database in the research and with the findings obtained, it was concluded that the field is new and up-to-date and needs to be studied more. When looking at the WoS categories of studies titled renewable energy in tourism enterprises; it was concluded that more energy fuel, green sustainable science technology, science themes were given weight. According to the network analysis, the most cited authors and countries' densities were determined and the intensive expressions in the network keywords in their studies titled renewable energy in tourism enterprises are renewable energy, renewable energy sources, sustainable tourism, sustainability, carbon dioxide (CO2) emissions, green marketing, blue economy, and energy efficiency.

This study aimed to examine the financial risk-taking behaviors of adult individuals diagnosed with attention deficit hyperactivity disorder (ADHD).
Abstract
Purpose
This study aimed to examine the financial risk-taking behaviors of adult individuals diagnosed with attention deficit hyperactivity disorder (ADHD).
Design/methodology/approach
The study was conducted with adults (n = 80) diagnosed with ADHD and healthy controls (n = 80). In order to measure risk-taking in the financial domain, the items in the investment and gambling sub-dimensions of the Domain-Specific Risk-Taking Scale (DOSPERT) were applied.
Findings
Adults with ADHD had higher investment and gambling risk-taking and expected benefits scores than the control group, and there was no difference between the two groups in terms of risk perceptions. In the regression analysis, there was a positive linear relationship between the investment and gambling risk-taking scores and the expected benefits scores in both groups. There was a negative linear relationship between investment risk-taking and risk perceptions scores only in the control group.
Originality/value
In terms of investment and gambling, both risk-taking and expected benefits are greater in individuals with ADHD. It has been observed that while healthy individuals take investment risks, they evaluate according to the expected benefits and risk perceptions, while individuals with ADHD make evaluations only according to the expected benefits, risk perceptions do not predict financial risk-taking in individuals with ADHD. When it comes to risk-taking related to gambling, both groups take risks only according to their expectations of benefits, not their perceptions of risk. The study provides outputs that can contribute to the literature in terms of the effects of ADHD diagnosis on financial decision-making processes in the context of risk-taking.

Abstract
Purpose
The purpose of this study is to identify the ways in which social entrepreneurs use rhetoric to establish legitimacy for themselves and their ventures. This is done by examining interviews with 19 social entrepreneurs in the city of Istanbul, Turkey. Most entrepreneurship studies are rooted in a positivist paradigm, but as there is need for qualitative research in entrepreneurship that allows for an in-depth study of a given phenomenon, the life story method is used as a methodological tool as scholars in rhetoric, technical and professional communication have pointed to narratives as viable sites of study.
Design/methodology/approach
This study used a linguistic focus on entrepreneurship research, thereby contributing to a growing body of literature and responding to Lounsbury and Glynn’s call for “a more ethnographic approach to entrepreneurial stories” to better understand how entrepreneurs use stories as a mechanism for resource and legitimacy acquisition.
Findings
This paper sought to identify the ways in which social entrepreneurs establish legitimacy for their ventures among various stakeholders, including investors as well as employees, customers and community members. This study aimed to investigate this particular field because, although there has been a recent growth in social entrepreneurial activity in the context of developing nations, the field is still emerging as an area for academic inquiry. Based on interviews with 19 social entrepreneurs in the city of Istanbul, Turkey, four key rhetorical strategies used to establish the legitimacy of social ventures among various stakeholders are identified.
Research limitations/implications
This study addresses issues related to entrepreneurship from a rhetorical perspective and helps explain the mechanisms through which entrepreneurial phenomena occur. With only 19 life story interviews acquired mostly through referrals, it is possible that the study did not have access to a sufficiently diverse group of social entrepreneurs. Also, having used a snowball sample, it is possible that isolated members of the community were under-sampled, whereas others who may have more extensive contacts and acquaintances were oversampled.
Practical implications
This research has implications for practice as well. New venture founders who enter into conversations with stakeholders can use this typology to assess and improve the language they use to claim legitimate distinctiveness.
Social implications
In addition to its theoretical implications, this research also has normative implications for social entrepreneurs. First, and most generally, findings suggest that social entrepreneurs should approach narrative construction and deployment purposively, not haphazardly. Crafting the narratives used to communicate about the key facets of a social venture to stakeholders is not “just” storytelling; rather, it is an activity that can have significant implications for a social venture’s ability to acquire resources. Second, beyond merely being conscious of narratives, social entrepreneurs also should not underemphasize the importance of being strategic about how they are used to communicate to audiences. In particular, it is important for entrepreneurs to realize that as powerful as their social-good narrative might be, not every audience wants to hear it.
Originality/value
This study addresses issues related to entrepreneurship from a rhetorical perspective and helps explain the mechanisms through which entrepreneurial phenomena occur. By integrating a rhetorical analysis with reflexive accounts from entrepreneurs, this work directly engages with Downing’s (2005) call to use such an approach to develop an enriched account of the duality of structure and agency in entrepreneurial endeavors. In doing so, it also responds to the call to challenge elite functionalist discourses in entrepreneurship research and put forward a view on entrepreneurial performance that acknowledges the socially dependent and constructed nature of such activity. This research has implications for practice as well. New venture founders who enter into conversations with stakeholders can use this typology to assess and improve the language they use to claim legitimate distinctiveness. The typology may, for example, help entrepreneurs who are preparing a business plan or a pitch for investors.

Abstract
Purpose
Workarounds are defined as user-formulated solutions that overcome the obstacles preventing the system's execution from the users' lenses. In this paper, the authors aim to analyze the workarounds in system implementations and post-implementations with reflections on different levels of resilience in the workplace.
Design/methodology/approach
In this paper, the authors conduct a critical review of enterprise resource planning (ERP) system workarounds by evaluating whether the workarounds are treated as resilience enhancers or as hinderers at multiple levels. While doing this evaluation, the authors try to understand the nature of the workarounds (self-serving, social-serving) with respective levels of analysis for resilience (ERP resilience, organizational resilience, team resilience, employee resilience) and to integrate the assessment of similar concepts to resilience such as adaptability, flexibility and agility (in survival and sustainability dimensions).
Findings
Workaround solutions can be treated as resilience enhancers when the alternative solutions overcome some systemic problems and prevent system failures in the short run, but in the long term, they should motivate positive change and organizational dynamics. Otherwise, weaknesses of informal workarounds may become embedded in practice, and prevent confronting and correcting the shortcomings of the system and thus harm resilience.
Originality/value
The differentiation of workarounds as self-serving or social-serving and the resilience perspective toward workarounds with different levels of analysis and integrating resilience relevant concepts such as adaptability, agility and flexibility are new as far as the authors know.

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
This article tackles the intersection of mothering and labor through the author's own experience as a feminist mother/manager from Istanbul, Turkey. It aims to revisit the first years of motherhood, exploring the struggle to invent a peculiar maternal subjectivity in opposition and negotiation with the patriarchal institution of motherhood, the new definition of maternal labor in a highly digital, neoliberal context and the issue of marital fairness in a dual-income heterosexual marriage.
Design/methodology/approach
The article presents an autoethnographic, retrospective and introspective inquiry into the first seven years of the author's mothering experience in order to offer an in-depth exploration of the various aspects of contemporary maternal labor.
Findings
The article shows how maternal labor has shifted in nature and expanded in scope in a contemporary non-Western context. It investigates the dissolution of the spatial, temporal and sensorial boundaries between the managerial labor dedicated to the workplace, and to the family. Highlighting the similarities of the two forms of labor, the article manifests the materiality, tangibility and visibility of maternal labor.
Research limitations/implications
Further intersectional studies shall be beneficial to redefine maternal labor in different contexts.
Practical implications
Departing and diverting from the terms “invisible labor” and “mental load”, the article suggests a shift in terminology to stress the multifaceted medley of managerial tasks mothers undertake today.
Originality/value
The article provides an original take on maternal labor through the first-hand experience of a middle-class, professional mother from Istanbul, Turkey.
