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.

This study explores the professional work of managers in professional service firms (PSFs) by focusing on the relational position of managers as they interface between diverse groups of actors and navigate a multiplicity of accountabilities.

Drawing on an ethnographic study of managers in a Brazilian PSF, this study demonstrates through observations, interviews and shadowing how PSF managers address multiple accountabilities in the conduct of professional work.

To navigate multiple accountabilities, PSF managers perform several forms of boundary work, which the authors conceptualize as “revamping” and “remolding” operations and “translating” and “transforming” understandings. The form of boundary work performed depends on the configuration of two elements of accountability demands: knowledge orientation and extent of exposure. Although analytically distinct, these elements intertwine, suggesting the need for a dynamic perspective on accountability. The analysis shows that professional work extends beyond fixed or passive views of hierarchical and intrinsic accountability to emphasize that managers exude accountability of an adaptive nature.

This study illustrates and theorizes the role of boundary work in PSFs, develops its link to accountability, and identifies its scholarly and practical affordances and limitations for understanding managers’ professional work when navigating multiple accountabilities.

The findings reveal perspectives and behaviors of managers embedded in PSFs, illustrating their unstructured and agentic experiences of accountability and boundary work in practice. The insights can be extended to other contexts where managers face multiple accountabilities in conducting professional work.

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.

This paper describes the process of developing training for student employees at a reference desk in which students assist peers and others in the community with research help.

This case study details the process as well as the challenges in developing training that is helpful for student employees in performing day-to-day tasks at a reference desk and incorporates diversity, equity, inclusion and accessibility (DEIA) and high-impact practices (HIPs).

Training for student employees that prepares them for library work and incorporates DEIA and HIPs can be developed. These ideas can be incorporated into training for all library employees, not just students.

This article aims to assist others in developing training for front-line student employees that incorporates DEIA and recognizes the importance of HIPs.

DEIA and HIPs are considered throughout the development and implementation of training for student employees. Librarians have been training student employees to assist their peers with research for many years. This approach goes beyond the training that is needed to do a job and takes DEIA and student development through HIPs into account.

Multi-well hydrofracturing is a key technology in engineering, and the evaluation, control and optimization of the fracturing network determine the recovery rate of unconventional oil and gas production. In engineering terms, altering well spacing and perforation initiation sequences changes fracture propagation behavior. Fracture propagation can result in fracture-to-fracture and well-to-well interactions. This may be attributed to the interference between fractures caused by squeezing of the reservoir strata. Meanwhile, the stratal movement caused by the propagation of the fractures may lead to either the secondary fracturing of wells with primary fractures or perforation to begin fracturing. Besides, the stratal compression and squeeze of multi-well hydrofracturing will cause earthquakes; the fracture size is different owing to the different fracturing scenarios, and the occurrence of induced microseismic events is still unknown; microseismic events also affect fracture orientation and deflection. If the mechanism of the above mechanical behavior cannot be clarified, optimizing the fracture network and reduce the induced microseismic disaster becomes difficult.

In this study, combined finite element-discrete element models were used to simulate the multi-well hydrofracturing. Numerical cases compared the fracture network, dynamic stratal movement and microseismic events at 50, 75 and 100 m well spacings, respectively, and varying initiation sequence of multiple horizontal wells.

From the results, fracture propagation in multi-well hydrofracturing may simulate the propagation and deflection of adjacent fractures and induce fracture-to-fracture and well-to-well interactions. As the well spacing increases, the effect of fracturing-induced stratal movement and squeezing deformation decrease. In alternate fracturing, starting from a well located in the middle can effectively reduce the influence of stratal movement on fracturing, and the fracturing scenario with cross-perforation can minimize the influence of stratal movement. The stratal movement between multiple wells is positively correlated to microseismic events, which behaviors can be effectively weakened by reducing the strata movement.

The fracture network, thermal-hydro-mechanical coupling, fracturing-induced stratal movement and microseismic events were analyzed. This study analyzed the intersection and propagation behavior of fractures in multi-well hydrofracturing, which can be used to evaluate and study the mechanism of hydrofracturing fracture network propagation in multiple horizontal wells and conduct fracture optimization research to form an optimized hydrofracturing scheme by reasonably arranging the spacing between wells and initiation sequences of perforation clusters.

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.
