This paper aims to study the influence that the second invariant of the rate-of-strain tensor of a power law polymeric fluid (aqueous solution of hydroxyethyl cellulose [HEC]) has on convective mixing performance downstream of a 3D confined oscillating prism. Newtonian and non-Newtonian Reynolds numbers, the mass concentration of HEC and prism oscillation frequency were varied.

A conceptual problem was designed. Its objective was to analyze the convective mixing of two adjacent flow streams when they pass around a moving confined prism. The rectangular prism had a square section, and its sinusoidal motion was prescribed inside a channel with a square section too. OpenFOAM libraries were used to simulate the flow field. Regarding prism motion, the icoDyMFoam solver was used. The problem was analyzed both at the global level (mixing parameter) and local level (detailed flow topology).

For constant Reynolds number, increasing mass concentrations of HEC (in the range from 0.2% to 0.5%) led to better mixing parameters. The improvement was linked to the effect that the second invariant of the rate-of-strain tensor had on flow topology. It was found that mixing is maximum when the prism motion and its wake (the frequency of the first instability) are synchronized. In practical terms, this means that the optimum stirring frequency does not need to be very high; it suffices that it ensures that synchronization occurs. The dominant vorticity shedding pattern found was the so-called 2P mode. However, a significant difference was found when compared to the free-stream situation. While in the former, the two vorticity regions that make up the 2P pair come from the prism, in the present confined case, one came from the prism, and the other came from the wall. Another difference was that in the present case, the 2P pairs were much more elongated than in the free stream case, and this had a significant influence on the stretching and bending of streak lines and, therefore, on mixing.

The study that has been presented has a practical industrial implication for the processes industry because it provides guidelines to design active mixers that deal with aqueous power law polymeric solutions. In parallel, it opens up some new research lines in the direction of studying whether the mixing concept might be modified so as to develop a fully passive system that could be far simpler and, possibly, more attractive to industry.

The originality and value of the study are associated to the systematic approach that has been followed. It has allowed to establish a clear pattern regarding the active mixing behavior of HEC solutions in confined flows. To the best of authors’ knowledge, this could be the first study of this type in the literature. Also, the study has contributed to understand the vorticity shedding patterns that appear in these types of problems and how they shape wake topology and, consequently, mixing performance. The finding that optimum mixing requires synchronization of stirring motion frequency and wake first natural frequency of instability may help to improve the design and operation of industrial mixers dealing with polymeric aqueous solutions.

In a previous research, the authors proposed a security information service, called Personalized Real-time Information with Security Map (PRISM), which personalizes the incident information based on living area of individual users. The purpose of this paper is to extend PRISM to conduct sophisticated analysis of street crimes. The extended features enable to look back on past incident information and perform statistical analysis.

To analyze street crimes around living area in more detail, the authors add three new features to PRISM: showing a past heat map, showing a heat map focused on specified type of incidents and showing statistics of incidents for every type. Using these features, the authors visualize the dynamic transition of street crimes in a specific area and the whole region within Kobe city. They also compare different districts by statistics of street crimes.

Dynamical visualization clarifies when, where and what kind of incident occurs frequently. Most incidents occurred along three train lines in Kobe city. Wild boars are only witnessed in a certain region. Statistics shows that the characteristics of street crimes is completely different depending on living area.

Previously, many studies have been conducted to clarify factors relevant to street crimes. However, these previous studies mainly focus on interesting regions as a whole, but do not consider individual’s living area. In this paper, the authors analyze street crimes according to users’ living area using personalized security information service PRISM.

The PRISM SaveScreen facility and function keys provide alternatives in producing data for budget planning and PRISM search cost estimation, and also facilitating PRISM search training. By combining the SaveScreen function key with frequently used PRISM function keys such as 〈SEND〉, 〈DISPLAY RECORD SEND〉, 〈FOR〉, and 〈BAC〉, the activities of a PRISM user can be recorded and stored in a predefined data file for later analyses. For example, from the results of the analyses, the usage levels of OCLC workstations and the approximate monthly PRISM search cost of each workstation were obtained. In addition, based on the recorded search activities, a retraining in PRISM search can be planned. Certainly, by familiarizing oneself with PRISM search commands and search structures, a user can perform cost‐effective and efficient searches. Toward that end, also presents methods of performing cost‐effective PRISM searches.

The case is suitable for all post-graduate students and executives doing a course in human resource management (HRM). The case will enable these students to apply concepts such as inclusion, empowerment, glass ceiling, in business situations involving women. It will help them to trace the evolution path for women employees who have the traits to lead a department or organisation and assume entrepreneurial roles.

The case study is particularly beneficial for MBA students specialising in HRM focussed on leadership and training. It can be used in courses such as gender and entrepreneurship for students of MBA entrepreneurship and MBA family business management. As the case is written in India, it can explore the gender issues in emerging markets surreptitiously. Most importantly, the case addresses COVID-19 perspective adequately, to teach modules embedded in main courses of any MBA program.

PRISM World Pvt Ltd is a leading training and consultancy firm in Delhi, India. The firm is owned and managed by a young woman Dr Anubha Walia. She started her career as a human resource manager in leading Indian companies, but somewhere down the line, she felt the job was not allowing her to realise the fullest potential. The Indian corporate training industry was male dominated with self-serving men, supporting the “glass ceiling”. To break the barrier, Anubha opened her training firm founded on the basis of a new philosophy, which should serve the ideals of helping and promoting women in workplace. This new philosophy was called PRISM. Anubha provided an inclusive environment which allowed her trainers to grow and feel empowered in a gender-biased industry.Very recently, when COVID-19 pandemic happened, female trainers were under tremendous strain as training requirements completely dried up, and they were rendered jobless. Most of these educated young women had small kids and paid monthly installments for their home loans, sharing the financial burden with their husbands. Some mature trainers were single women who had to support themselves through savings in these difficult times. But Anubha’s sense of empowerment at PRISM helped these women to do things which made their livelihoods turnaround even in uncertain circumstances. PRISM philosophy made a turnaround too. While employees were thinking of abandoning their companies and vice-versa, trainers at PRISM went for free webinars to draw clients to their firms and changed the concept of training and delivery in corona times.PRISM acquired a new meaning of wellness and spirituality in these difficult times and soared ahead successfully.

The case study hopes to achieve the following pedagogical objectives: 1. To educate students on manners and traits of women entrepreneurs. Besides, the usual difficulties of financing and running a business, women face adversities at home in the form of lack of access to working capital, trust deficit amongst family and friends. Basically, lack of support system to propels women into the tougher role of an entrepreneur graduating from a regular employee. Gender becomes a disability, which women had to fight in the workplace. The case introduces the PRISM philosophy as a unique methodology to inculcate inclusivity in work environment leading to women empowerment. 2. To outline all issues related to ‘glass ceiling” – the barrier which existed in the corporate world for businesswomen. Students need to know about problems women faced in the business environment as well as shortcomings within themselves, which can make them unproductive. 3. To align students first hand with the challenges of COVID-19 pandemic, specific to women. The case talks about educated young and mature women in Anubha’s firm PRISM, fighting for lost livelihood owing to reduced levels of business. But women are known to be highly resilient and empowered in the right direction will turnaround the situation in their favour.

The case has tremendous social implication for educated working women in traditional patriarchal Indian societies. Though a sizeable percentage of women have achieved higher education and started working in a male-dominated corporate world, only a small number of them are visible as entrepreneurs and/or leaders. Every woman needs to trace her journey from an employee to an entrepreneur or a CEO to assume a position of leadership. This case can be an eye opener for many such ambitious women who can build small- to mid-size businesses in a short span of time. Digital intervention is very important in COVID times to stay afloat. The author has shared links for many videos which can disseminate ideas for digital transformation in businesses. The case tries to showcase an ideal inclusive environment which will propel women to achieve their latent goals and desires breaking the 'glass ceiling.'

This paper aims to compare the performance of flow pulsation versus flow stirring in the context of mixing of a passive scalar at moderate Reynolds numbers in confined flows. This comparison has been undertaken in two limits: diffusion can be neglected as compared to convection (very large Peclet) and diffusion and convection effects are comparable. The comparison was performed both in terms of global parameters: pumping power and mixing efficiency and local flow topology.

The study has been addressed by setting up a common conceptual three-dimensional problem that consisted of the mixing of two parallel streams in a square section channel past a square section prism. Stirring and pulsation frequencies and amplitudes were changed and combined at an inlet Reynolds number of 200. The numerical model was solved using a finite volume formulation by adapting a series of open-source OpenFOAM computational fluid dynamic (CFD) libraries. For cases with flow pulsation, the icoFoam solver for laminar incompressible transient flows was used. For cases with stirring, the icoDyMFoam solver, which uses the arbitrary Lagrangian–Eulerian method for the description of the moving dynamical mesh, was used to model the prism motion. At the local flow topology level, a new method was proposed to analyze mixing. Time evolution of folding and wrinkling of sheets made up of virtual particles that travel along streak lines was quantified by generating lower rank projections of the sheets onto the spaces spanned by the main eigenvectors of an appropriate space-temporal data decomposition.

In the limit when convection is dominant, the results showed the superior performance of stirring versus flow pulsation both in terms of mixing and required pumping power. In the cases with finite Peclet, the mixing parameters by stirring and flow pulsation were comparable, but pulsation required larger pumping power than stirring. For some precise synchronization of stirring and pulsation, the mixing parameter reached its maximum, although at the expense of higher pumping power. At the local flow topology level, the new method proposed to quantify mixing has been found to correlate well with the global mixing parameter.

A new systematic comparative study of two methods, stirring and pulsation, to achieve mixing of passive scalars in the mini scale for confined flows has been presented. The main value, apart from the conclusions, is that both methods have been tested against the same flow configuration, which allows for a self-consistent comparison. Of particular interest is the fact that it has been found that accurate synchronization of both methods yields mixing parameters higher than those associated to both methods taken separately. This suggests that it is possible to synchronize mixing methods of a different nature to achieve optimum designs. The new theoretical method that has been proposed to understand the mixing performance at the local level has shown promising results, and it is the intention of the authors to test its validity in a broader range of flow parameters. All these findings could be taken as potential guidelines for the design of mixing processes in the mini scale in the process industry.

The purpose of this paper is to develop an exclusive review framework for the Performance Prism.

An extensive literature survey on performance measurement is used to identify the main aspects of the review in such systems. Various dimensions related to the characteristics of Performance Prism are explored. All the findings are then rationally put together to develop the proposed conceptual framework.

The paper presents a conceptual model to review performance measurement systems (PMS) which are designed based on Performance Prism. The presented framework categorizes review processes and tools into two main categories; Business Performance Review (BPRw) and Performance Measurement System Review (PMSR). In BPRw, a loop is presented in three levels – with regards to the five facets of Performance Prism – which indicates the performance management process. PMSR deals with reviewing the efficiency and effectiveness of the design and implementation of the PMS itself. Several methods and tools have been gathered from the literature (e.g. relevance test, measures profile, etc) in this section to examine the relevance of measures, and some have been introduced (including a method to determine inconsistencies in organization's performance trends between stakeholder, strategic and operational level) to study and challenge the validity of strategic assumptions and strategies, and appropriateness of infrastructure. Implications of various factors such as organizational culture, change management, and characteristics of the measures (level of the measure, managers who receive reports including the measure, and supporting infrastructure) are highlighted.

In contrast to PMS design and implementation, research on PMS review is limited. This is more evident in the literature concerning Performance Prism. The empirical evidence of usefulness is beyond the scope of this article.

The framework provides a procedural action for reviewing both business performance and PMS performance when applying the Performance Prism in practice and provides a foundation for further empirical research.

The paper adds to the body of literature, by proposing a comprehensive review framework to be used in Performance Prism.

This study aims to examine the potential for the Performance Prism (Neely et al., 2001) to influence the perceived outcome of a planned organizational change. General Systems Theory (Ruben, 1979; Thayer, 1968; vonBertalanffy, 1975) is used to understand the differences in stakeholder perception throughout the institution.

Thirty-two participants from four educational support services departments and the senior leadership group of a university were interviewed. A grounded theory, constant comparative method (Glaser and Strauss, 1967) was used to generate themes and codes from transcripts.

Findings suggest that implementers failed to adequately assess all employees’ satisfaction and contributions prior to implementation. Using the Performance Prism could have been the key to perceptions of success about the change effort.

Research comparing the Performance Prism to implemented planned change efforts not using the Performance Prism is limited, especially in higher education. Also limited is research using the Performance Prism and General Systems Theory.

Understanding stakeholder satisfaction and contributions throughout the organizational system are vital to planned change efforts, especially in loosely coupled organizations (Gallivan, 2001; Neely et al., 2001; Ruben, 1979). Using the Performance Prism is valuable to further this understanding.

The study advances the literature about the use of the Performance Prism in higher education by providing an understanding of the implications of neglecting to consider all stakeholders at all levels of the system in planned change efforts.

Detailed results of numerical calculations of transient, 2D incompressible flow around and in the wake of a square prism at Re = 100, 200 and 500 are presented. An implicit finite‐difference operator‐splitting method, a version of the known SIMPLEC‐like method on a staggered grid, is described. Appropriate theoretical results are presented. The method has second‐order accuracy in space, conserving mass, momentum and kinetic energy. A new modification of the multigrid method is employed to solve the elliptic pressure problem. Calculations are performed on a sequence of spatial grids with up to 401 × 321 grid points, at sequentially halved time steps to ensure grid‐independent results. Three types of flow are shown to exist at Re = 500: a steady‐state unstable flow and two which are transient, fully periodic and asymmetric about the centre line but mirror symmetric to each other. Discrete frequency spectra of drag and lift coefficients are presented.

Engagement, motivation, and persistence are usually associated with positive outcomes. However, too much of it can overtax our psychophysiological system and put it at risk. On the basis of a neuro-dynamic personality and self-regulation model, we explain the neurobehavioral mechanisms presumably underlying engagement and how engagement, when overtaxing the individual, becomes automatically inhibited for reasons of protection. We explain how different intensities and patterns of engagement may relate to personality traits such as Self-directedness, Conscientiousness, Drive for Reward, and Absorption, which we conceive of as functions or strategies of adaptive neurobehavioral systems. We describe how protective inhibitions and personality traits contribute to phenomena such as disengagement and increased effort-sense in chronic fatigue conditions, which often affect professions involving high socio-emotional interactions. By doing so we adduce evidence on hemispheric asymmetry of motivation, neuromodulation by dopamine, self-determination, task engagement, and physiological disengagement. Not least, we discuss educational implications of our model.

This study aims to develop a framework for cybersecurity risk assessment in an organization. Existing cybersecurity frameworks are complex and implementation oriented. The framework can be systematically used to assess the strategic orientation of a firm with respect to its cybersecurity posture. The goal is to assist top-management-team with tailoring their decision-making about security investments while managing cyber risk at their organization.

A thematic analysis of existing publications using content analysis techniques generates the initial set of keywords of significance. Additional factor analysis using the keywords provides us with a framework comprising of five pillars comprising prioritize, resource, implement, standardize and monitor (PRISM) for assessing a firm’s strategic cybersecurity orientation.

The primary contribution is the development of a novel PRISM framework, which enables cyber decision-makers to identify and operationalize a tailored approach to address risk management and cybersecurity problems. PRISM framework evaluation will help organizations identify and implement the most tailored risk management and cybersecurity approach applicable to their problem(s).

The new norm is for companies to realize that data stratification in cyberspace extends throughout their organizations, intertwining their need for cybersecurity within business operations. This paper fulfills an identified need improve the ability of company leaders, as CIOs and others, to address the growing problem of how organizations can better handle cyber threats by using an approach that is a methodology for cross-organization cybersecurity risk management.
