The purpose of this paper is two-fold: to describe how Lean methodology can be used, during the COVID-19 pandemic, to enhance the learning experience for non-traditional adult learners (NALs) and to explore attitudes and perceptions of students toward the integration of Lean methodology in online classes.

Qualitative semi-structured interviews were used to collect data for the study. NALs were invited to participate in 60–75 min semi-structured interviews. These interviews allowed researchers to gain an in-depth understanding of a participant’s experience. A six-step thematic analysis framework was used to conduct the data analysis.

This paper presents a Lean model that can be implemented in an online medium of instruction. The core concepts of Lean methodology: jidoka, just-in-time, customer-centered approach, team involvement and standardization and how these can be used in online learning have been described in-depth. In total, 40 students participated in the semi-structured interviews. Four themes emerged from the data analysis: work-life balance; lack of standardization; learning online classes and connection to the workplace.

These findings could help academic institutions, instructors and course designers as they work on implementing new teaching and learning strategies for NALs.

There is extremely limited evidence on the usage of Lean methods for NALs in a public health crisis. As academic institutions move to the online medium of instruction to contain public health problems, this project can provide important practical tips to instructors.

The purpose of this paper is to study, examine and apply lean management principles to the curriculum revision and internship placement process in an academic program at an institution of higher education.

This paper consists of two sections. The first section reviews the literature on lean principles, lean tools, nonvalue-added activities and the application of lean methodology to academic settings. The second section presents a case study, where a team of faculty members applied lean principles to the process of curriculum revision and internship placement at an academic institution.

Lean principles can be successfully applied to curricular revision and the internship placement process. By applying the concepts of value, identification of value stream, removal of wasteful activities to achieve flow and creation of a pull-based system, faculty and program leaders can streamline processes at academic institutions. Furthermore, ongoing data collection helps to foster the culture of continuous improvement and ensure that processes are revisited and adapted to meet the needs of customers.

This paper is of value to faculty members and college administrators interested in applying lean principles to academic processes. Usage of lean methodology may lead to the identification and elimination of waste in curriculum and the field placement process.

This manuscript can provide a structure for the application of lean in academic processes at institutions of higher education.

The purpose of this paper is to explore and examine attitudes and perceptions of leaders on application of quality improvement (QI) strategies in a palliative and hospice care organization.

This study employed qualitative research methodology where leaders working in a hospice and palliative care organization were invited to participate in 45–60-min-long semi-structured interview. Interviews were recorded and transcribed verbatim. Qualitative content analysis was utilized to analyze the data collected during participant interviews.

Seven leaders participated in the interviews. Five themes were developed from data analysis: patient-centered care; continuous QI; leadership involvement and commitment; communication as a foundation for QI; and perceived barriers. Data analysis suggests that use of QI approach in palliative and hospice care enhances the quality of care provided for patients, and can help improve patient satisfaction.

Because there is a paucity of research on implementation of QI strategies in hospice and palliative care settings, this research can have wide practical implications. This research can provide useful practical tips to leaders as they work on implementing QI projects in their organization.

This manuscript can be of value to leaders, administrators and academicians who are interested in applying QI principles to healthcare processes especially in palliative and hospice care settings. Ability to work with others, solid communication and involvement of employees from all levels can help in streamlining current systems of care.

The purpose of this paper is to describe how lean management principles can be used in teaching and learning processes while preparing classes for non-traditional adult learners (NALs). Careful planning and the application of lean methods can result in NALs’ enhanced engagement and success at academic institutions.

The fundamental concepts of the lean philosophy, value, value streams, flow, pull and perfection were used to carefully examine the teaching and learning process at academic institutions. Efforts were made to identify non-value-added activities in the process and explore methods to enhance the learning experience for NALs.

This paper provides a comprehensive approach on how to plan a class using lean methodology. Identification and removal of non-value-added activities in teaching and learning processes can help to engage students in the classroom.

This research has practical implications for academic institutions. Incorporation of lean methodology may lead to identification and elimination of waste in teaching and learning processes. This may allow instructors to re-evaluate existing course delivery methods and offer equal or higher quality curricula while reducing cost at the same time.

Lean management principles have been successfully applied to a variety of administrative processes at academic institutions. However, there exists very limited research that show lean can be effectively used in designing curricula for NALs. This project can provide a framework for the application of lean while teaching and learning at academic institutions.

The manufacturing industry is presently experiencing technological disruption on a global scale. Consequently, to tackle such disruption, firms are identifying a volatile, uncertain, complex and ambiguous (VUCA) scenario and seeking ways to counter it. Accordingly, this paper aims to investigate the employee performance through assessing organizational citizenship behaviour (OCB) among the shop floor employees of the fast-moving consumer goods (FMCG) industry where a high-performance work system (HPWS) has been implemented.

A descriptive research design was used in the study, and 395 shop floor employees working in leading multinational firms, with a minimum global turnover of US$1bn, were interviewed. These manufacturing firms were located in three industrial clusters in the northern part of India.

The results indicate that HPWS influences OCB. Most of the dimensions of HPWS and OCB were found to be positively associated. The findings also disprove the labour process theory in the context of the study.

The findings report a broad view of the relationship between HPWS and OCB in the Indian manufacturing context. The study offers the practical insights that HPWS is a universally accepted framework and that organizations should focus on the effective implementation of HPWS in a VUCA scenario, which is in line with past studies. The study also provides future directions for research.

This paper has established the relationship between HPWS and OCB in the manufacturing sector, especially for shop floor employees.

The purpose of this paper is a new thin-film based sensor proposed for sensitive and selective detection of mercury (Hg²⁺) ions in water. The thin-film platform is easy to use and quick for heavy metal ions (HMIs) detection in the picomolar range. Ion-selective self-assembled monolayer's (SAM) of thiol used for the detection of HMIs above the Au/Ti top surface.

A thin-film based platform is suitable for the on-field experiments and testing of water samples. HMIs (antigen) and thiol-based SAM (antibody) interaction results change in surface morphology and topography. In this study, the authors have used different characterization techniques to check the selectivity of the proposed method. This change in the morphology and topography of thin-film sensor checked with Fourier-transform infrared spectroscopy, surface-enhanced Raman scattering spectroscopy, atomic force microscopy and scanning electron microscopy with energy dispersive x-ray analysis used for high-resolution images.

This thin-film based platform is straightforward to use and suitable for real-time detection of HMIs at the picomolar range. This thin-film based sensor platform capable of achieving a lower limit of detection (LOD) 27.42 ng/mL (136.56 pM) using SAM of Homocysteine-Pyridinedicarboxylic acid to detect Hg²⁺ ions.

A thin-film based technology is perfect for real-time testing and removal of HMIs, but the LOD is higher as compared to microcantilever-based devices.

The excessive use and commercialization of nanoparticle (NPs) are quickly expanding their toxic impact on health and the environment. The proposed method used the combination of thin-film and NPs, to overcome the limitation of NPs-based technique and have picomolar (136.56 pM) range of HMIs detection. The proposed thin-film-based sensor shows excellent repeatability and the method is highly reliable for toxic Hg²⁺ ions detection. The main advantage of the proposed thin-film sensor is its ability to selectively remove the Hg²⁺ ions from water samples just like a filter and a sensor for detection at picomolar range makes this method best among the other current-state of the art techniques.

The purpose of this study is to perform comprehensive investigation to assess the mechanical properties of nano-modified ternary cement concrete blend. Nano silica (NS) (1%, 2% and 3%) and waste marble dust powder (MD) (5%, 10% and 15%) was incorporated as a fractional substitution of cement in the concrete matrix.

In this experimental study, 10 cementitious blends were prepared and tested for compressive strength, flexural strength, splitting tensile strength and static modulus of elasticity. The microstructural characteristics of these blends were also explored using a scanning electron microscope along with energy dispersive spectroscopy and X-ray reflection.

The results indicate an enhancement in mechanical properties and refinement in pore structure due to improved pozzolanic activities of NS and the filling effect of MD.

To the best of the authors’ knowledge, no study has reported the mechanical and microstructural behavior of concrete containing marble and NS.

The purpose of this paper is to present an analytical study on an unsteady magnetohydrodynamic (MHD) boundary layer flow of a rotating viscoelastic fluid over an infinite vertical porous plate embedded in a uniform porous medium with oscillating free-stream taking Hall and ion-slip currents into account. The unsteady MHD flow in the rotating fluid system is generated due to the buoyancy forces arising from temperature and concentration differences in the field of gravity and oscillatory movement of the free-stream.

The resulting partial differential equations governing the fluid motion are solved analytically using the regular perturbation method by assuming a very small viscoelastic parameter. In order to note the influences of various system parameters and to discuss the important flow features, the numerical results for fluid velocity, temperature and species concentration are computed and depicted graphically vs boundary layer parameter whereas skin friction, Nusselt number and Sherwood number at the plate are computed and presented in tabular form.

An interesting observation is recorded that there occurs a reversal flow in the secondary flow direction due to the movement of the free stream. It is also noted that a decrease in the suction parameter gives a rise in momentum, thermal and concentration boundary layer thicknesses.

Very little research work is reported in the literature on non-Newtonian fluid dynamics where unsteady flow in the system arises due to time-dependent movement of the plate. The motive of the present analytical study is to analyse the influences of Hall and ion-slip currents on unsteady MHD natural convection flow of a rotating viscoelastic fluid (non-Newtonian fluid) over an infinite vertical porous plate embedded in a uniform porous medium with oscillating free-stream.

In the present investigation, hydromagnetic boundary layer flow of Walters’-B fluid over a vertical porous surface implanted in a porous material under the action of a strong external applied magnetic field and rotation is presented. In several industrial applications, the external applied magnetic field is strong enough to produce Hall and ion-slip currents. Thus, the influence of Hall and ion-slip currents is also considered in this analysis. The flow through configuration is generated because of time varying motion of the free-stream and buoyancy action.

Regular perturbation scheme is used to obtain the solution of the system of coupled partial differential equations representing the mathematical model of the problem. Numerical computation has been performed to notice the change in flow behavior and the numerical results for velocity field, temperature field, species concentration, skin friction, rate of heat and mass transfer are presented through graphs and tables.

An important fact noticed that the exponential time varying motion of the free-stream induces reverse flow in the direction perpendicular to the main flow. Rising values of the strength of the applied magnetic field give increment in the fluid velocity in the neighbourhood of the vertical surface, this may cause because of the exponential motion of the free-stream. The behaviour of the Darcian drag force is similar as magnetic field on fluid flow.

In literature, very less research works are available on Walters’-B fluid where unsteadiness in the system occurs because of time varying motion of the free-stream. In this paper, the authors have made an attempt to study the action of Hall and ion-slip currents, rotation and external applied magnetic field on hydromagnetic boundary layer flow of Walters’-B fluid over a vertical surface implanted in a porous material.

The purpose of this paper is to deal with an unsteady natural convection flow of a rotating fluid past an exponential accelerated vertical plate. The effect of Hall current, ion-slip and magnetic field is considered. Two types of plate temperature, namely, uniform and ramped temperature are considered to model heat transfer analysis.

The Laplace transform technique is employed to find the closed form solutions for velocity, temperature and concentration.

The effects of flow governing parameters on the velocity profile, temperature profile, concentration profile, skin friction, Nusselt and Sherwood numbers are discussed and presented through graphs and tables. It is found that fluid velocity in the primary flow direction decreases with the increase in the magnetic parameter.

First time in the literature, the authors obtained closed form solution to natural convection flow of a rotating fluid past an exponential accelerated vertical plate.
