This study aims to provide a review for scour in complex rivers and streams with coarser bed material, steep longitudinal bed slopes and dynamic environments, in the interest of the safety and the economy of hydraulic structures. The knowledge of scour in such geographical complexities is very crucial for a comprehensive understanding of scour failures and for establishing definitive criteria to bridge this major research gap.

The existing available literature shows significant work done in case of silt, sand and small sized coarser bed material but any substantial work for bed material of gravel size or above is lacking, resulting in a wide gap. Though some researchers have attempted to explore possibilities of refining the existing models by adding pier size, shape, sediment non-uniformity and armouring effects, which otherwise have been given a miss by the various researchers, including the pioneer in the field Lacey–Inglis (1930). But still, a rational model for scour estimation in such complex conditions for global use is yet to come. This is because all the parameters governing the scour have not been studied properly till date as is evident from the globally available literature and is witnessed in the field too, in recurrent failure of hydraulic structures especially bridges.

The researchers presume that the finer materials move only as a result of erosion. However, in actual field conditions, it has been observed that the large-sized stones also roll down and cause huge erosion along the river bed and damage the hydraulic structures, especially in the steep river/stream beds along hilly slopes. This fact has been overlooked in the models available globally and has been highlighted only in the current work in an attempt to recognize this major research gap. A study carried out on a number of streams globally and in Jammu and Kashmir, India also, has shown that in steep river and stream beds with bed material consisting of gravel size or greater than gravel, large scour holes ranging from 1 m to 5 m were created by furious floods, and due to other unknown forces along the channel path and near foundations of hydraulic structures.

To the best of the authors’ knowledge, this work is purely original.

This study examines the association between emotional intelligence (EI) and the tendency of future accountants to rationalize and engage in occupational fraud.

The study adopts a survey methodology and uses a questionnaire containing a fraud scenario and EI construct to gather data from 225 participants. It performed a Cronbach alpha to assess the measurement parameters consistency of EI and fraud tendency and employed Pearson correlation and regression analysis to test its hypothesis.

The study found that future accountants in Nigeria are emotionally intelligent and have a high fraud tendency. Also, it found a significant and positive association between EI and fraud tendency, suggesting that future accountants that are emotionally intelligent have a higher tendency to rationalize and engage in occupational fraud. In addition, the study found that academic intelligence, a control variable, positively associates with fraud tendency.

The study offers rare insights into the fraud tendency of future accountants, which would benefit the counter fraud community in Nigeria and other developing countries. Recruiters and employers will find the study beneficial in decision-making on job recruitment, placements and moral orientation for prospective accountant employees.

The study is the first to directly associate EI with the fraud tendency of future accountants from a developing country with high fraud profile and underdeveloped counter fraud strategy. Thus, it provides a benchmark for future studies in other developing countries.

Emotional intelligence (EI) and self-concept (SC) play a very important role in one’s life. The purpose of this paper is to investigate the SC and EI of tribal and nontribal university students.

The research used a quantitative approach, 100 nontribal (50 male and 50 female) and 100 tribal (50 male and 50 female) students were selected by nonprobability sampling method. The Bangla version of the self-concept questionnaire (Beck et al., 2001) and the emotional intelligence questionnaire (Hyde et al., 2002) were used to measure the SC and EI of students. Pearson correlation, t-test and post hoc tests were used for statistical analysis.

The findings of this study showed that the tribal and nontribal students differ significantly on the measure of SC and EI (p < 0.01). Although nontribal students showed higher SC than tribal students, tribal students showed a higher level of EI than nontribal students. The results also showed that gender significantly affects SC and EI (p < 0.01). Males have higher SC and EI than females. Furthermore, the study revealed that socioeconomic status differs significantly in the case of SC. Finally, the result also showed a significant positive correlation (r = 0.245, p < 0.01) between SC and EI.

The results of the research are only based on the students of one university besides the sample size is limited.

This research allowed the authors to determine the practical implications. The findings suggest that there is a significant difference in SC and EI between tribal and nontribal students, with nontribal students showing higher levels of SC. This implies that interventions and programs aimed at enhancing SC may be particularly beneficial for tribal students. The study also reveals that there are significant differences in SC and EI between tribal and nontribal adolescent boys and girls. This highlights the importance of considering gender differences when designing interventions to improve SC and EI among tribal and nontribal students. Moreover, educators, parents and policymakers can use these findings to develop targeted interventions and strategies to enhance SC among tribal students, with the aim of improving their overall well-being, academic achievements and success in life.

This paper adds to the literature on the SC and EI of tribal and nontribal university students by describing the difference in levels and a significant correlation. This paper obtains an innovative statistical approach to develop the findings so that information can be used in the future.

The issue of cybersecurity has been cast as the focal point of a fight between two conflicting governance models: the nation-state model of national security and the global governance model of multi-stakeholder collaboration, as seen in forums like IGF, IETF, ICANN, etc. There is a strange disconnect, however, between this supposed fight and the actual control over cybersecurity “on the ground”. This paper aims to reconnect discourse and control via a property rights approach, where control is located first and foremost in ownership.

This paper first conceptualizes current governance mechanisms through ownership and property rights. These concepts locate control over internet resources. They also help us understand ongoing shifts in control. Such shifts in governance are actually happening, security governance is being patched left and right, but these arrangements bear little resemblance to either the national security model of states or the global model of multi-stakeholder collaboration. With the conceptualization in hand, the paper then presents case studies of governance that have emerged around specific security externalities.

While not all mechanisms are equally effective, in each of the studied areas, the author found evidence of private actors partially internalizing the externalities, mostly on a voluntary basis and through network governance mechanisms. No one thinks that this is enough, but it is a starting point. Future research is needed to identify how these mechanisms can be extended or supplemented to further improve the governance of cybersecurity.

This paper bridges together the disconnected research communities on governance and (technical) cybersecurity.

The participation of trans people is increasingly being framed as a defining issue for women's sport. A dominant narrative, promoted by various newly formed feminist organizations located in the Global North, is that (cisgender) women's sport will be forever changed – and negatively so – by the increased recognition and sports participation of trans athletes. The message is the following: first, that biological sex is fundamentally binary; second, that the place of ‘females’ in sport depends on the recognition of this biological ‘truth’; and third, that sports policymakers must choose between advancing the rights of interests of (cisgender) women or those of trans athletes, but can't do both. I call this phenomenon biofeminism: the wielding of scientific knowledge and expertise to claim binary, biological sex difference as the ‘true’ basis of (cisgender) women's experience and her rights. In this chapter, I offer an exploratory, empirical account of this variety of feminist mobilization by analyzing an awareness-raising event held in the United Kingdom in 2019. I approach this event as an opportunity to better understand how biofeminist actors are organizing, their epistemic strategies and the political frames they rely upon to give meaning to ideologies of binary sex difference and impact policy and legislation. Given the unfinished business of realizing gender equity within the institution of sport, I reflect on how women's sports organizations might counter biofeminist mobilization and pursue allyship between cis and trans women.

Given the growing importance of religious tourism, the purpose of this paper is to present a review of the literature around the area.

All papers with the term “religious tourism” have been searched via Emerald Insight from January 2006 to December 2017. The search was run in June 2017 for the last time and all early cite papers falling under the criteria were also included. This has ensured that key literature produced after the seminal work by Timothy and Olsen (Eds) (2006) has been reviewed. Certain exclusions apply which have been listed in the paper.

Key themes from the literature on religious tourism along with new developments and overlaps with other tourism sectors have been highlighted.

This paper reviews literature spanning more than a decade on religious tourism.

In this chapter, we examine several attributes of lone wolf terrorists and how their activities are temporally and geospatially patterned. In particular, we demonstrate how precursor behaviors and attack characteristics of lone wolves are similar and different compared to those of group-based terrorists.

Based on data drawn from the American Terrorism Study (ATS), we examine 268 federal terrorism “indictees” linked to 264 incidents. Three types of loners are identified based on group affiliations and levels of assistance in preparing for and executing terrorist attacks. A series of analyses comparatively examine loners who had no assistance and those actors that did.

The results of this study suggest that lone wolf terrorists are more educated and socially isolated than group-based actors. Lone wolves also engage in less precursor activities than group actors, but are willing to travel greater distances to prepare for and execute attacks. Explanations for why lone wolves are able to “survive” longer than terrorist groups by avoiding arrest may in part stem from their ability to temporally and geospatially position their planning and preparatory activities.

Studies on lone wolf terrorism remain few and many are plagued by methodological and conceptual limitations. The current study adds to this growing literature by relying on lone wolf terrorism data recently made available by the American Terrorism Study (ATS). Our findings are valuable for members of the law enforcement and intelligence communities responsible for the early detection and prevention of lone wolf terrorism in the United States.

In 1979, P. Wintgen obtained a basic relationship between the extrinsic normal curvature the intrinsic Gauss curvature, and squared mean curvature of any surface in a Euclidean 4-space with the equality holding if and only if the curvature ellipse is a circle. In 1999, P. J. De Smet, F. Dillen, L. Verstraelen and L. Vrancken gave a conjecture of Wintgen inequality, named as the DDVV-conjecture, for general Riemannian submanifolds in real space forms. Later on, this conjecture was proven to be true by Z. Lu and by Ge and Z. Tang independently. Since then, the study of Wintgen’s inequalities and Wintgen ideal submanifolds has attracted many researchers, and a lot of interesting results have been found during the last 15 years. The main purpose of this paper is to extend this conjecture of Wintgen inequality for bi-slant submanifold in conformal Sasakian space form endowed with a quarter symmetric metric connection.

The authors used standard technique for obtaining generalized Wintgen inequality for bi-slant submanifold in conformal Sasakian space form endowed with a quarter symmetric metric connection.

The authors establish the generalized Wintgen inequality for bi-slant submanifold in conformal Sasakian space form endowed with a quarter symmetric metric connection, and also find conditions under which the equality holds. Some particular cases are also stated.

The research may be a challenge for new developments focused on new relationships in terms of various invariants, for different types of submanifolds in that ambient space with several connections.

Bi-slant submanifolds of S-manifolds are introduced, and some examples of these submanifolds are presented.

Some properties of D_i-geodesic and D_i-umbilical bi-slant submanifolds are examined.

The Riemannian curvature invariants of these submanifolds are computed, and some results are discussed with the help of these invariants.

The topic is original, and the manuscript has not been submitted to any other journal.

The main impetus of the current paper is to identify and prioritize the work–family balance (WFB) satisfaction attributes specifically for working sole mothers' by deploying the Kano technique and weighted average method.

A multi-stage methodology has been used in the present analysis. Initially, the Kano method has been utilized to categorize the WFB satisfaction attributes using a three-dimensional WFB satisfaction scale. Afterward, the satisfaction coefficient technique was employed on Kano outcomes to get the WFB satisfaction and dissatisfaction index. Subsequently, the weighted average method was employed to prioritize the WFB satisfaction attributes.

Findings uncovered the significance of a non-linear association between WFB attributes and employed sole mothers' WFB satisfaction. The findings revealed that one-dimensional and must-be-based WFB satisfaction attributes are responsible for sole mothers' WFB satisfaction and employing organizations must not overlook them. Additionally, the results of weighted average method-based prioritization can help organizations to focus on particular WFB satisfaction criteria according to their priority level.

The findings are useful for WFB policy-makers and managers to formulate a suitable WFB strategy specifically for single mothers.

Results provide a path for employers to minimize the work–family role conflict and societal dissatisfaction that helps sole mothers to attain the desired WFB.

This study first employed a novel approach that incorporates the Kano application with the weighted average method in order to prioritize the WFB satisfaction attributes for lone mothers.
