The purpose of this study is to examine the impact of internal and external corporate governance mechanisms on the probability of engaging in tax aggressiveness.

This study uses a sample of 52 firms listed on the Tunis stock exchange observed over the 2003–2016 period (The authors had to stop sampling in 2016 because the measurement of tax aggressiveness requires 4 years after the year of study. Therefore, the data on the measurement of tax aggressiveness were collected until 2020). This paper uses the logistic regression technique.

The results of the first logistic regression show that ownership structure and the supervision role of the tax authorities are determining factors that explain tax aggressiveness; while, the attributes of the board of directors does not seem to explain the probability of engaging in aggressive tax strategies. To further probe this question, the authors carried out additional analyses that examine the moderating effect of controlling shareholders on the relationship between the attributes of the board and tax aggressiveness. The results of our additional regressions indicate that the effect of these attributes improves in cases of non-presence of a controlling shareholder. This implies that the role that the board of directors can play in controlling management is possibly conditioned by the presence or no of control block holders.

The major limitation of this study is that it concentrates only on Tunisian listed companies because they are the only companies the financial statements of which are publicly available in Tunisia. Although the sample is relatively small due to the problem of data availability, it appears to be satisfactory given the 15-year sampling period (i.e. from 2003 to 2016).

The results of the study may help Tunisian regulators create requirements for corporate governance (such as the size of the board of directors and audit committee or the concentration of ownership). Moreover, this study not only focuses on the effect of corporate governance mechanisms on tax aggressiveness but also provides shareholders with information on the governance mechanisms to which they should pay more attention in their desire to obtain more efficient tax results.

The findings are also useful for tax policymakers seeking to identify the circumstances that give rise to an increased risk of tax aggressiveness, as tax aggressive behavior and the resulting non-payment of taxes also have societal implications. In fact, taxes also play an important role in financing the provision of public goods, making corporation tax a matter of public concern.

The present study differs from others in the existing literature by designing a more precise measure of tax aggressiveness and examining the interaction between two internal governance mechanisms; the presence of a controlling shareholder and the attributes of the board of directors. This study also examines the impact of the control exercised by the tax authorities on the behavior of firms in terms of tax aggressiveness.

The purpose of this paper is to close the gap between the theoretical nature of existing contributions in customer engagement value (CEV) and its need to practically empower business decisions. This is done by proposing a framework that consists of three techniques, each of which combines the components of CEV to make it more comprehensive and applicable. The paper also reviews and analyzes the work that has been done so far in the area of CEV whether in business to business (B2B), business to consumer (B2C) or consumer to consumer (C2C) markets.

CEV is a comprehensive term that measures the total value of the customer through capturing his transactional and non-transactional behaviors. Hence, it is an essential term for measuring the value of the customer in direct marketing. This motivates researchers to compete in developing models to maximize CEV. Meanwhile, most of the existing models are conceptual and the majority of them lack applicability due to many reasons. First, these models relied on a linear version of the CEV model, hence double-counting the value of the customer; also they weighted the components of CEV equally, which is unrealistic. Finally, the effect of the environmental components in determining the engagement level of each customer was almost ignored. In this paper, two main contributions are presented. First, a summary and analysis of the contributions of the literature in the CEV field for different market types whether in B2C, B2B or C2C. Furthermore, three modifications are added to the existing models. The first model introduces a non-linear relationship of the components of CEV. The second model is a weighted linear model of these components. Finally, the third model adds the environmental factors to the CEV components. All the proposed models are theoretical in nature, however, these models are expected to show superiority when being applied to real data sets due to their ability to capture the complexity in the relationship between the firm and its customers in real-life situations. The proposed models are expected to attract the practitioners and other researchers and they both are encouraged to apply the proposed models on real-life data sets, test their performance, compare them against each other, to be able to apply each of them on the best suitable data set and business scenario.

Based on the review and analysis that has been done on about 87 papers, it is found that the majority of the contributions that have been done in the area of CEV are theoretical in nature, in spite of the effectiveness of CEV in empowering business decision. It is also found that few researchers proposed a set of theoretical comprehensive frameworks that combined CEV’s components together. Meanwhile, those frameworks are not practically applicable.

Although the contribution of the proposed models expected to attract both researchers and practitioners, these are not applied to real-life case studies to prove their effectiveness.

The research in this paper has many industrial and managerial implications. First, it helps managers and decision takers to treat the customers as assets and cost-free resources who can work with the firm to achieve what’s both aims to (i.e. increase customer satisfaction and firm’s profitability). Second, it helps the firm to determine the total value of each customer and treat its customers accordingly. Third, it empowers the managers to do target marketing, based on grouping the customers upon their total engagement. This would save time and cost and for sure increase the profitability and customer satisfaction. Forth, the proposed models take into consideration not only the transactional behavior of the customers but also the non-transactional factors that play a significant role in formulating the relationship between the firm and its customers.

The purpose of this paper is to study how CEO power impact corporate tax avoidance. In particular, this paper aims to empirically examine the moderating impact of institutional ownership on the relationship between CEO power and corporate tax avoidance.

The multivariate regression model is used for hypothesis testing using a sample of 308 firm-year observations of Tunisian listed companies during the 2013-2019 period.

The results show that CEO power is negatively associated with corporate tax avoidance and that institutional ownership significantly accentuates the CEO power’s effect on corporate tax avoidance. This implies that CEOs, when monitored by institutional investors, behave less opportunistically resulting in less tax avoidance.

Our findings have significant implications for managers, legislators, tax authorities and shareholders. They showed that CEO duality, tenure and ownership can mitigate the corporate tax avoidance in Tunisian companies. These findings can, hence, guide the development of future regulations and policies. Moreover, our results provide evidence that owning of shares by institutional investors is beneficial for reducing corporate tax avoidance. Thus, policymakers and regulatory bodies should consider adding regulations to the structure of corporate ownership to promote institutional ownership and consequently control corporate tax avoidance in Tunisian companies.

This study differs from prior studies in several ways. First, it addressed the emerging market, namely the Tunisian one. Knowing the notable differences in institutional setting and corporate governance structure between developed and emerging markets, this study will shed additional light in this area. Second, it proposes the establishment of a moderated relationship between CEO power and corporate tax avoidance around institutional ownership. Unlike prior studies that only examined the simple relationship between CEO power and corporate tax avoidance, this study went further to investigate how institutional ownership potentially moderates this relationship.

The current study is exploring factors affecting social and sharing behavioral intentions. The paper proposes a new theory, the consumer social behavior theory, which aids in understanding social behaviors. This is through the convergence of the theory of planned behavior (TPB) and norm activation theory (NAT) to foster the understanding of sharing and social behaviors. Religiosity, as a cultural and psychological factor, along with five major predictors of sharing practices are also incorporated. These predictors are economic benefits, sustainability, enjoyment, trust and difficulties in sharing practices.

The current study takes a new route through proposing a new theoretical contribution and developing a new theory termed consumer social behavior theory (CSBT) to be commonly used in social behavioral contexts.

The CSBT is an output of integrating two prominent theories in pro-social and pro-environmental contexts. It is found that integrating both theories help in thoroughly examining behavioral intentions. Religiosity is found to significantly impact intentions towards social behaviors, yet no study examined its role in sharing and social behaviors contexts.

This study is contributing to and enriching the sharing economy research domain through new theoretical developments. A theory adaptation for TPB and NAT was conducted to advance a thorough understanding of sharing and social behavioral intentions. This work is considered the first of its kind to develop an integrated view for sharing and social behaviors.

This paper presents a new numerical model that, unlike most existing ones, can solve the whole liquid sloshing, nonlinear, moving boundary problem with free surface undergoing small to very large deformations without imposing any linearization assumptions.

The time‐dependent, unknown, irregular physical domain is mapped onto a rectangular computational domain. The explicit form of the mapping function is unknown and is determined as part of the solution. Temporal discretization is based on one‐step implicit method. Second‐order, finite‐difference approximations are used for spatial discretizations.

The performance of the algorithm has been verified through convergence tests. Comparison between numerical and experimental results has indicated that the algorithm can accurately predict the sloshing motion of the liquid undergoing large interfacial deformations.

The ability to model liquid sloshing motion under conditions leading to large interfacial deformations utilizing the model presented in this paper improves our ability to understand the problem of sloshing motion in tuned liquid dampers (TLDs), which would eventually help in constructing more effective TLDs.

This study sheds light on the determinants related to the corporate board of directors and the firms’ ownership nature of tax aggressiveness strategies of Tunisian listed firms and what could be their effect on its level in a postrevolution context.

Our research considers only nonfinancial firms listed in the Tunisian stock exchange during the 2011–2017 period. It is based on unbalanced panel data.

Findings suggest that women presence on the corporate board, CEO duality, the managerial and institutional ownership regularize significantly the level and the management's behavior of engagement in tax aggressiveness practices and reduce the firm’s overall risks of its consequences in terms of tax positions stability.

Our investigation considers only nonfinancial firms to avoid noisy results and for the significant differences between accounting standards within financial and nonfinancial firms, besides sample homogeneity and comparability considerations.

This study provides evidence that some governance mechanisms, even reasonably dedicated to consider the risk of tax aggressiveness and to prevent its consequences, have a paradoxical effect and amplify the tax aggressiveness’ level rather than defending the firm’s viability and its financial stability. It offers signals to managers about specific governance attributes that strengthen and/or control the extent of tax aggressive strategies.

This research gives a particular road map for society, investors and practitioners to depict the firms’ level of tax aggressiveness and especially to understand its attributes related to the corporate board of directors and the ownership's nature through evidences from a postrevolution context.

Our research contributes to prior literature by examining the effect of corporate board characteristics and different ownership natures on the extent of tax aggressiveness during and after the revolution period in Tunisia and confirms and infers some prior findings of tax aggressive determinants in underdevelopment context.

Some researchers regard discretionary accrual (DA) as one of the factors that drive corporate managers to conduct tax planning (Scott, 2009; Basri and Buchari, 2017). Based on agency theory and positive accounting theory, corporate managers can transform accounting information and manipulate firm earnings to reduce tax liability. There is a lot of research concerning earnings management and tax planning in the developed economy. These studies include Wang and Chen (2012) and Pettersson and Wu (2015). In the emerging economies, it includes Jamei and Khedri (2016), Kurniasih and Sulardi Suranta (2017), Prastiwi (2017), Almashaqbeh et al. (2018), Bayunanda et al. (2018), Rani et al. (2018) and Kałdoński and Jewartowski (2019). It is important to note that none of the research mentioned above has evaluated the impact of real earnings management (REM) on tax planning in Nigeria. While in the developed economy only Kałdoński and Jewartowski (2019) used REM as an explanatory variable, while the majority of studies used DA. Consequently, no study has used REM to moderate the relationship between financial attributes and tax planning. Despite the widespread notion, as well as positive accounting theory, tax planning theory that financial attributes (profitability, leverage, liquidity and firm growth), REM and DA motivate tax planning, previous investigations have produced mixed results (Dwenger and Steiner, 2009; Wang and Chen, 2012; Chen and Zolotoy, 2014; Aghouei and Moradi, 2015; Pettersson and Wu, 2015; Ribeiro, 2015; Chen et al., 2016; Jamei and Khedri, 2016; Ogbeide, 2017; Yuniawati et al., 2017; Chen and Lin, 2017; Firmansyah and Febriyanto, 2018; Prastiwi, 2018; Rani et al., 2018; Kibiya and Aminu, 2019; Kałdoński and Jewartowski, 2019 and Siyanbonla, 2021). This study aims to use REM as a moderator to examine the relationship between financial attributes and tax planning whether it will strengthen or weaken the relationship.

The study examines the impact of financial attributes on the corporate tax planning of listed manufacturing firms in Nigeria. It also tests for the moderating effect of REM on the relationship between financial attributes and tax planning. Data for the study was sourced from the annual reports of sampled manufacturing firms. The study used the panel data methodology for analysis. The study used fixed effect estimation to interpret the parsimonious model and random effect was used to interpret the moderated model. The study documented that financial leverage has a positive significant influence on the tax planning of the sampled manufacturing firms. While firm growth has a negative significant impact on the tax planning of listed manufacturing firms in Nigeria. REM has a positive significant impact on tax planning. Also, REM moderate significantly the relationship between financial attributes on one hand and tax planning on the other. The study recommends that firms should go for more debt to take advantage of the tax shield of interest on the debt. Also, firm management should use non-current debt to finance non-current assets and use current debt to finance current assets to avoid the risk of taking over or liquidation. The study also recommends that firm management should engage in intercompany and intracompany transactions by selling their goods to affiliates in countries with low prices and low tax rates. A firm should also overproduce goods to have high production costs and high closing inventory since real earning management significantly reduces tax liabilities by deferring income into a later year.

The study documented that financial leverage has a positive and significant influence on the tax planning of the sampled manufacturing firms. While firm growth has a negative but significant impact on the tax planning of listed manufacturing firms in Nigeria. REM has a positive and significant impact on tax planning. Also, REM moderate significantly the relationship between financial attributes on one hand and tax planning on the other.

A pandemic causes abrupt and unanticipated disruptions in many facets of society. A lot of authorities have quickly turned to online teaching methods. The best methods for online teaching have become a hot topic of discussion due to this urgent fast transmission. It was difficult to teach physiology to medical and paramedical students online because of concerns about how to give the students an effective interactive online teaching practice and how to guarantee successful outcomes. Therefore, three approaches have been individually applied to medical and nursing students for the first time in the physiology department of the Faculty of Medicine in Rabigh, King Abdulaziz University. Through online lectures and assignments, the strategies attempted to capture the students’ interest and interaction. The second-year nursing students were given a mind map project to complete after the lecture. The third-year medical students used a crossword puzzle game to test the students’ understanding. The third-year medical students were presented with short stories to better comprehend the physiological processes covered in the lectures. Overall, the three instructional strategies received positive feedback from the students. Incorporating such cutting-edge and imaginative educational approaches, in conclusion, could significantly aid in managing the pressures that arise during pandemics.

This paper aims to assess the psychological impact of home confinement in Tunisian medical students and analyze the relationship between psychopathology and cognitive emotion regulation strategies.

In total, 251 medical students who have been in home confinement accepted to participate in an online questionnaire survey. They completed depression, anxiety and stress scale, beck hopelessness scale and cognitive emotion regulation questionnaire.

Moderate to extremely severe levels of depression, anxiety and stress were reported by 57.4%, 51.0% and 31.4% of medical students, respectively. Based on the cut-off value of nine, 31.1% of the participants showed high levels of hopelessness. Hierarchical regression analysis identified four cognitive emotion regulation strategies as significant independent contributors to psychopathology above and beyond home confinement related variables. Self-blame positively predicted stress. Catastrophizing positively predicted anxiety and hopelessness. Refocusing on planning negatively predicted anxiety. Positive reappraisal negatively predicted hopelessness.

Cognitive emotion regulation strategies may constitute a valuable target of preventive and interventional measures to improve medical students’ mental health.

A unique feature of this study is the demonstration of the important role played by cognitive emotion regulation strategies in predicting anxiety, stress and hopelessness in medical students. In the context of mandatory home confinement, these cognitive strategies were significant predictors of psychopathology above and beyond home confinement related variables.
