Abstract
Purpose
Turkey hosts the majority of Syrians who fled their country due to the Syrian Civil War that started in 2011, and Syrians mostly live in the provinces most affected by the Kahramanmaraş earthquakes. The purpose of this study is to analyze the effect of the presence of disadvantaged population on disaster risk in Turkey, a disaster country, through the Kahramanmaraş earthquakes and Syrian asylum-seekers, based on the claim that the vulnerability caused by this additional population residing in the provinces most affected by the Kahramanmaraş earthquakes is a factor that will increase the disastrousness of the earthquakes.
Design/methodology/approach
Based on the mathematical model used in the calculation of the Human Development Index, the study comparatively calculates the vulnerability of the Turkish and Syrian populations residing in the earthquake-affected provinces by taking into account population density, gender, age, education and employment factors.
Findings
The findings of the analysis show that the vulnerability of Syrian asylum seekers in Kilis, Gaziantep and Hatay provinces is higher than the vulnerability of the Turkish population.
Originality/value
This paper shows significant findings on the effects of disadvantaged groups residing in a disaster-prone area concerning the consequences of the devastating earthquakes that occurred on February 6, 2023 in the southern region of Turkey.

Abstract
Purpose
The purpose of this paper is to revisit the question of whether analysts anticipate accruals’ predicted reversals (or persistence) of future earnings. Prior evidence documents that analysts who provide information to investors are over optimistic about firms with high working capital (WC) accruals. The authors propose that empirical models using WC accruals alone may be incomplete and hence not entirely appropriate to assess the level of analysts’ understanding of accruals. The authors argue that analysts’ optimism about WC accruals might not be due to their lack of sophistication, but rather driven by incomplete accrual information embedded in forecast accuracy tests.
Design/methodology/approach
The authors use non-financial US firms for the period between 1976 and 2013. The authors define earnings forecast errors as the analysts’ consensus earnings forecasts minus the actual earnings provided by IBES deflated by share price from CRSP. The authors carry out forecast error regressions on individual accrual components by decomposing total accruals into categories. The authors perform the tests across 12 months starting from the initial analysts’ forecasts, which are generally issued in the first month after the prior period earnings announcement date. The final sample contains 48,142 firm–year observations per month.
Findings
The empirical tests show no correlation between analysts’ forecast errors and revised total accruals. The findings are robust to different samples, periods, model specifications, decile ranked accruals, high accruals, absolute forecast errors, controlling for cash flows (CF) and high accounting conservatism. The findings imply that if analysts are to achieve more accurate forecasts, they should be considering all rather than some accrual components. The authors interpret this evidence as an indication of analysts’ relative sophistication with respect to accruals.
Research limitations/implications
The authors recognise that analysts’ correct anticipation of accruals’ persistence does not mean that their earnings forecasts are entirely free of bias. Analysts can make forecast errors for various reasons including strategic biases. For instance, the tests show pessimistic forecast errors with respect to CF, which is in line with similar findings in prior research (Drake and Myers, 2011). Hence, the authors suggest that future research examine this correlation in greater depth as CF components are with the highest level of persistence, and hence should be predicted most accurately.
Practical implications
The results imply that the argument about analysts’ lack of sophistication with respect to accruals’ persistence is not warranted. The results imply that forecasts appear to contribute to market efficiency. Another implication is that analysts seem to utilise all relevant accrual information in their forecasts, hence traditional accrual definition should be revised in future studies. Key inferences of the paper imply that the growing use of analysts’ reports by institutional investors and money managers in their decision-making processes is justified despite the debate in the prior literature on the role and the reputation of analysts as surrogates of market expectations.
Originality/value
The research sheds a new light on the question whether sell-side security analysts are able to anticipate the persistence of accruals in future earnings.

Abstract
Purpose
The purpose of this paper is to illustrate how the numerical solution of the Burgers' equation is obtained using the methods of cubic B‐spline collocation and quadratic B‐spline Galerkin over the geometrically graded mesh.
Design/methodology/approach
The spatial domain is partitioned into geometrically graded mesh. The finite element methods are constructed within the Galerkin and collocation methods using an expansion of the quadratic and cubic B‐splines as an approximate function, respectively, over this mesh.
Findings
When the higher errors are observed at near boundaries for shock‐like and travelling wave solutions of the Burgers' equation, accuracy of the defined methods increase by using finer mesh at near this boundary.
Originality/value
Over the geometrically graded mesh definitions of the quadratic B‐spline Galerkin and cubic B‐spline collocation are given.

Abstract
Purpose
The purpose of this study was to investigate eVisa applications. eVisa is a service that falls under eTourism, whose growing use can be attributed to its ability to simplify the process of obtaining a visa. The objectives of this study were twofold: to explore the eVisa experience of tourists who have previously visited Turkey by using the service and to analyse the perceptions of stakeholders who have contributed to eVisa.
Design/methodology/approach
The present research has utilised two methodologies within the context of qualitative research methods. Data were gathered from tourists by using reviews (n = 1690) and in-depth interviews key actors (n = 4), which represent consumers and contributors’ perspectives on the eVisa system, respectively. While consumers dictate the demand of the service, contributors control its supply. The contributors referenced herein are relevant eVisa stakeholders in Antalya.
Findings
The research findings revealed eVisa facilitation’s positive effects on a destination’s image and tourists’ intentions to revisit destinations compared to when they use traditional visa-obtaining processes. The research findings then present suitable data for destination managers and policymakers regarding eVisa facilitation, followed by this study’s conclusions and implications.
Research limitations/implications
eVisa facilitation can foster demand for travel and tourism while maintaining bureaucratic elements of the traditional visa procedure. From a psychological perspective, eVisa facilitation can positively affect travel motivation to certain destinations where eVisas are applicable, as well as positively influence intentions to revisit tourist destinations.
Originality/value
The originality and uniqueness of the present study lies in its contribution to the increasing recognition of the significance and positive impacts of eVisa facilitation on travel and tourism demand.

Abstract
Purpose
The purpose of this study is to examine the influences of transformational leadership behaviors on followers’ task performance and organizational citizenship behaviors, the potential mediating role of affective trust and moderating effect of follower tenure with leader in these relationships.
Design/methodology/approach
The authors collected survey data from 197 employees from various organizations in Turkey, operating in several sectors. To test the relationships among study variables, the authors followed the moderated mediation procedure suggested by Hayes (2013).
Findings
The findings indicated that transformational leadership behaviors have significant positive effects on both followers’ task performance and organizational citizenship behaviors. Furthermore, mediational analyses showed that affective trust mediated the relationship between transformational leadership behaviors and followers’ task performance. Moreover, the moderation analysis shows that the effect of transformational leadership behaviors on affective trust depended on leader–follower dyadic tenure, with the effect of transformational leadership behaviors being greater at high level of leader–follower dyadic tenure.
Research limitations/implications
This study provides evidence of the positive relationship of transformational leadership behaviors with followers’ affective trust at work and task performance. Such knowledge suggests that improving leaders’ skills and capabilities in terms of transformational leadership through training might lead organizations to work more effectively.
Originality/value
This study contributes to the existing literature by showing the importance of affective trust, explaining why transformational leaders can motivate and influence followers to achieve a higher performance. In addition, this research provides knowledge about transformational leadership effectiveness in developing countries, mainly in Turkey.

Abstract
Purpose
This study produced epoxy-filled urea-formaldehyde (UF) microcapsules (MCs) and T-403 amine MCs using the in situ technique. The Taguchi method was used to determine the effects of the control factors (temperature, stirring speed, core-shell ratio and surfactant concentration) affecting MCs’ core diameter and core content and optimizing their optimum levels with a single criterion. Optimum control factor levels, which simultaneously provide maximum core diameter and core content of MCs, were determined by the PROMETHEE-GAIA multi-criteria optimization method. In addition, the optimized MC yield was analyzed by thermal camera images and compression test.
Design/methodology/approach
Microcracks in materials used for aerospace vehicles and automotive parts cause serious problems, so research on self-healing in materials science becomes critical. The damages caused by micro-cracks need to heal themselves quickly. The study has three aims: (1) production of self-healing MCs, mechanical and chemical characterization of produced MCs, (2) single-criteria and multi-criteria optimization of parameters providing maximum MC core diameter and core content, (3) investigation of self-healing property of produced MCs and evaluation. Firstly, MCs were produced to achieve these goals.
Findings
The optimized micro cures are buried in the epoxy matrix at different concentrations. Thermal camera images after damage indicate the presence of healing. An epoxy-amine MC consisting of a 10% by weight filled aluminum sandwich panel was prepared and subjected to a quasi-static compression test. It was determined that there is a strong bond between the UF shell and the epoxy resin.
Originality/value
The optimization of production factors has been realized to produce the most efficient MCs that heal using less expensive and more accessible methods.

Abstract
Purpose
By solving a long-wave evolution model numerically for power-law fluids, the authors aim to investigate the hydrodynamic and thermal characteristics of thermocapillary flow in an evaporating thin liquid film of pseudoplastic fluid.
Design/methodology/approach
The flow reversal attributed to the thermocapillary action is manifestly discernible through the streamline plots.
Findings
The thermocapillary strength is closely related to the viscosity of the fluid, besides its surface tension. The thermocapillary flow prevails in both Newtonian and pseudoplastic fluids at a large Marangoni number and the thermocapillary effect is more significant in the former. The overestimate in the Newtonian fluid is larger than that in the pseudoplastic fluid, owing to the shear-thinning characteristics of the latter.
Originality/value
This study provides insights into the essential attributes of the underlying flow characteristics in affecting the thermal behavior of thermocapillary convection in an evaporating thin liquid film of the shear-thinning fluids.
