In this study, 2D density-based SST K-turbulence model with compressibility effect is used to observe the flow separation and shock wave interactions of the flow. The wall static pressure and Mach number differences are also evaluated. This study aims to discuss the aforementioned objectives

This study outlines the evaluation of the performance of a 2D convergent–divergent nozzle with various triangular jet tab configurations that can be used for effective thrust vectoring of aerial vehicles.

From the study, it is seen that the shadow effect induced by the tab with a height of 30% produces higher oblique wave deflection and higher thrust deflection at the exit nozzle. The numerical calculation concluded that thrust vector efficiency of 30% jet tab is, 0.46%. In the case of 10% jet tab height the thrust vector efficiency is higher, i.e. 1.647%.

2D study.

The optimization will open up a new focus in TVC that can be implemented for effective attitude control in aircrafts.

Used in future aircrafts.

The influence of shadowing ratio with different tab heights at different Mach numbers has not been reported in the previous studies. Few of the studies on jet tab are focused on the acoustic studies and not pertaining to the aerodynamic aspects. The multi jet configuration, the combination of location, shapes and other parametric analysis have not been covered in the previous studied.

The purpose of this paper is to explore how hierarchical accountability can be enacted and accounting control systems mobilized in a way that promotes a sense of felt responsibility.

The paper draws on interviews, shadowing and observations to explore the implementation of a strategy for “increasing accountability” in a Norwegian Oil Company. The case provided an opportunity to explore the dynamics of hierarchical accountability and felt responsibility, and in particular Roberts (2009) concept of “intelligent accountability”, in an empirical context.

The case study explores how the strategy of increasing accountability at OilCo was enacted around three operational issues; the control of costs, roles and relationships in the complex matrix structure, and the operation of the management system. It traces how the long history of Beyond Budgeting practices and philosophy in OilCo resulted both in an explicit recognition of the incompleteness of accounting numbers, and trust-based practices which avoided many of the dysfunctional individual and organizational effects typically associated with the exercise of hierarchical control.

The paper explores empirically how OilCo’s embrace of Beyond Budgeting practices and philosophy had created the conditions under which a more intelligent form of accountability could emerge. As a European case study, it calls into question the Anglo-American tradition of accounting research which suggests that externally imposed accountability within a hierarchy mitigates against employees’ felt responsibility.

This paper aims to examine how auditors make sense of the ill-theorized and contentious notion of other comprehensive income (OCI), specifically by uncovering their use of metaphors to make OCI plausible and intelligible.

This interpretative paper draws on a collection of 21 interviews with experienced auditors. The analysis first uncovers metaphors that naturally surface within the talk and sensemaking of auditors about OCI (elicited metaphors). The authors then encapsulate these elicited metaphors into second-order constructs (projected metaphors) to synthesize and further explain auditors’ practical sensemaking.

Auditors conceive OCI as a “safety” that ensures the well-functioning of fair value accounting, metaphorically qualifying this notion as a “necessary evil”, a “passage obligé”, and a “parking lot” resolving fair value-related issues and aberrations. Auditors also metaphorize OCI as a “purifier” that allows “polluted”, “noisy”, and “unloved” items to be “parked” outside net income.

The study’s findings further the understanding of auditors’ tendency to remain uncritical throughout their sensemaking process. Making sense of professional standards of practice through metaphors indubitably involves shadowing and silencing other worldviews.

This paper extends knowledge of auditors’ sensemaking, specifically showing how auditors easily make sense of complex notions even in the absence of conceptual grounds. This study also highlights that metaphors are a powerful sensemaking device that auditors mobilize to render complex notions intelligible and mitigate IFRS inconsistencies.

The study examined capacity-building practices for librarians' effective library service delivery in Federal University Libraries in Nigeria.

The design for this paper was a descriptive survey research design. Data was collected using a questionnaire from a total number of 178 respondents. Collected data were analyzed using mean scores and standard deviation.

The findings reveal that learning capacity-building practices such as rotating members of staff for wider experience exist in these libraries. Learning capacity-building practices contributes to effective service delivery by enhancing various library services. Results also show that there are challenges confronting learning capacity-building practices which include inadequate funding. For these libraries to perform to their highest potentials, their learning capacity needs to be built and developed.

The major limitation of this study is the tendency of the respondents to fake their responses which may arise from their personal biases.

Therefore, university library management and university administrators should as a matter of urgency develop policies that will ensure that capacities are built for better service delivery or risk users losing interest in the library.

The study examined a vital dimension of capacity build, which is learning capacity building. The findings will help university administrators and library management to know the different learning capacity-building practices that exist in the various libraries and the extent to which these practices are important and relevant for effective service delivery. This will assist them in adopting relevant and adequate learning capacity-building strategies and guiding them in formulating effective capacity-building policies.

While the main emotional labor strategies are well-documented, the manner in which professionals navigate emotional rules within the workplace and effectively perform emotional labor is less understood. With this contribution, I aim to unveil “the good, the bad and the ugly” of emotional labor as a dynamic theatrical performance.

Focusing on three geriatric long-term care units within a French public hospital, this qualitative study relies on two sets of data (observation and interviews). Deeply rooted within the field of study, the chosen methodological approach substantializes the subtle hues of the emotional experience at work and targets resonance rather than generalization.

Using the theatrical metaphor, this research underlines the role of space in the practice of emotional labor in a unique way. It identifies the main emotionalized zones or emotional regions (front, back, transitional, mixed) and details their characteristics, before unearthing the nonlinearity and polyphonic quality of emotional labor performance and the versatility needed to that effect. Indeed, this research shows how health-care professionals juggle with the specificities of each region, as well as how space generates both constraints and resources. By combining static and dynamic prisms, diverse instantiations of hybridity and spatial in-betweens, anchored in liminality and trajectories, are revealed.

This research adds to the current body of literature on the concept of emotional labor by shedding light on its highly dynamic and interactional nature, revealing different levels of porosity between emotional regions and how the characteristics of each type of area can taint others and increase/decrease the occupational health costs of emotional labor. The study also raises questions about the interplay of emotional labor performance with the level of humanization/dehumanization of elderly people. Given the global demographics about an aging population, this gives food for thought at a social level.

The purpose of this study was to examine the lived experiences of working mothers during the first year of the COVID-19 pandemic and assess their perceptions of the types of training opportunities that would help advance their careers as they navigated pandemic-related challenges.

In study 1, 53 participants responded to an online survey that included open-ended questions regarding the impact COVID-19 has had on their careers and desires they have for training to ameliorate these concerns. For study 2, 10 participants completed an interview that included open-ended questions regarding workplace changes and professional development/training opportunities since the pandemic.

Thematic analysis showed mothers facing several setbacks in their careers, including delays, loss of hours and wages, childcare stressors and strained or lost relationships with colleagues and supervisors. A small number of participants also reported some surprisingly positive experiences, such as a push toward career innovation. Participants reported little to no exposure to career development opportunities and expressed a desire for training for leadership and interpersonal connection in the workplace.

Although quantitative data have been helpful in identifying and quantifying growing gender gaps in work during the pandemic, the qualitative analyses the authors used highlight how recent difficulties encountered by working mothers risk a growing gender gap in work and career mobility as women in the leadership pipeline struggle with challenges. Further, the findings suggest ways that women in management can support the working mothers on their staff, including by suggesting ways additional training may address some concerns.

The utilisation of renewable energy sources for generating electricity and potable water is one of the most sustainable approaches in the current scenario. Therefore, the current research aims to design and develop a novel co-generation system to address the electricity and potable water needs of rural areas.

The cogeneration system mainly consists of a solar parabolic dish concentrator (SPDC) system with a concentrated photo-voltaic module at the receiver for electricity generation. It is further integrated with a low-temperature thermal desalination (LTTD) system for generating potable water. Also, a novel corn cob filtration system is introduced for the pre-treatment to reduce the salt content in seawater before circulating it into the receiver of the SPDC system. The designed novel co-generation system has been numerically and experimentally tested to analyse the performance at Karaikal, U.T. of Puducherry, India.

Because of the pre-treatment with a corn cob, the scale formation in the pipes of the SPDC system is significantly reduced, which enhances the efficiency of the system. It is observed that the conductivity, pH and TDS of seawater are reduced significantly after the pre-treatment by the corncob filtration system. Also, the integrated system is capable of generating 6–8 litres of potable water per day.

The integration of the corncob filtration system reduced the scaling formation compared to the general circulation of water in the hoses. Also, the integrated SPDC and LTTD systems are comparatively economical to generate higher yields of clean water than solar stills.

Emotions are everywhere and, as multiple scholars have argued, can be considered a fundamental part of the human experience. Individuals are expected to behave in socially appropriate ways in a variety of public and private social situations, which often involve managing one's emotions. The management and regulation of emotions are also key components of effective school leadership. This chapter unpacks the emotional aspects of school leadership by exploring how the management of emotions is fundamental to the success of headmasters, principals, vice-principals, and other school-level leaders. I also provide the rationale for using the term ‘school-level leaders’ and call for emotional authenticity in educational leadership. Then I outline several benefits an increased scholarly and practical focus on the emotional aspects of school-level leadership offers for teachers and other school staff, school-level leaders themselves, and the students they serve on a daily basis. I also provide a short description of the methodology used for the participant quotes used to add richness and contextualize key themes explored in Chapters 4 and 5. The chapter concludes with an outline of how the rest of this book is organized and offers additional insight into the topics explored in the forthcoming chapters.

The purpose of this study is to synthesize the current turnover literature that has investigated the nonfinancial antecedents of turnover intention across generations. This paper provides an integrative and analytical review of prior empirical studies with two research questions: What nonfinancial factors influencing employee turnover have been empirically identified across different generations? and What generational commonalities and uniqueness exist among the turnover antecedents?

To identify nonfinancial antecedents of employee turnover, an integrative literature review that allows a systematic process of searching and selecting literature was conducted. While synthesizing the antecedents identified in the articles, the authors were able to categorize them at three different levels: individual, group and organizational

The authors discuss each antecedent according to three categories: individual, group and organizational levels. Based on the findings from the first research question, the authors further explore the commonalities and uniqueness among three generations (i.e. Millennials, Generation X and older workers).

This study found both generational commonalities and uniqueness in terms of turnover intention antecedents. Based on the findings of the study, the authors discuss how to facilitate these common factors across all generations as well as considering the factors unique to each generation. Differentiation within organizations regarding retention strategies should yield positive results for both employees and organizations.

This study aims to examine the nonlinear threshold effect of shadow economy on sustainable development in Africa while providing additional evidence on how this nonlinear threshold effect play out in economies with high and low developed financial/credit markets.

This study uses 37 African economies between 2009 and 2017 in a dynamic GMM panel model that controls for country, year and technological effects to ensure consistency and reliability of results and findings.

The results reveal that there is an inverted nonlinear U-shape nexus between the size of shadow economy and sustainable development in both short run and long run in Africa and across economies with high and low developed credit/financial market. Also, the threshold points beyond which the size of shadow economies dampens sustainable development is lower for economies with high financial/credit market development and higher in the long run.

These results have policy implications and recommendations and suggest that shadow economies can be beneficial to sustainable development particularly when the size of shadow economies are restrained from increasing beyond certain thresholds/levels. Moreso, to restrict the adverse effect of shadow economies on sustainable development, policymakers can rely on developing their financial/credit markets to tame the destructive nature of shadow economies on sustainable development. These results are robust to technological, year/time and country effects.

To the best of the author’s knowledge, this study examines for the first in the context of Africa, the nonlinear effect of shadow economies on sustainable development under low and high developed financial markets.
