Abstract

Purpose

The current work aims to propose a finite element (FE) simulation methodology to predict the formability of friction stir processed (FSPed) tubes by end forming. Moreover, a strain mapping method is also presented to predict the end forming instabilities.

Design/methodology/approach

In this work, FE simulation of end forming of raw tubes and FSPed AA6063-T6 tubes are done using Abaqus (explicit) incorporating anisotropic properties of the raw tube and FSPed zone. Actual thickness of the FSPed zone is also implemented. Expansion, reduction and beading are the end forming operations considered. Load requirement and instabilities are predicted. A new method “strain mapping method” is followed to predict the failure instabilities in expansion and beading, while during reduction, wrinkling is predicted by FE simulations. Lab scale experiments on FSP and end forming are done for validation at various rotational speeds.

Findings

Results reveal that in the case of expansion and reduction of FSPed tubes, forming load predictions are accurate, while in beading, after initiation of bead, predictions are not accurate. Experimental observation on the type of instability is consistently predicted during numerical simulations. Prediction of displacement at failure by strain mapping method is encouraging in most of the cases including those that are FSPed. Hence, it is suggested that the method can be utilized to evaluate the onset of failure during tube expansion and beading.

Originality/value

FE simulation methodology including anisotropic properties of raw tube and FSPed tubes is proposed, which is not attempted until now even for normal tubes. Strain mapping method is easy to implement for instability predictions, which is done usually by failure theories and forming limit diagram.

Case overview

Roopa Rani, co-founded a digital design company, DesignTheme Innoventics (DTI), with her husband Yoganand, in November 2007, on the first floor of their residence. Yoganand’s creativity and Roopa’s determination made them bootstrap, scale slow and steady. As a novice to the industry, the initial days posed many challenges. Roopa hired artists to be appointed as designers, which gave them a unique selling preposition. They progressed slowly from a team of 2 to 20, with a revenue of INR 0.3M per annum to INR 12M per annum. As the company grew, Roopa wanted Yoganand’s support in handling the responsibilities, and hence, converted DTI into a limited liability partnership in 2013 and the couple were directors. As the client base improved, the need for shifting to a bigger space became more evident. A calculative risk-taker, Roopa, was forced to move DTI to a bigger office space end 2017, with a rent of INR60,000 per month. Meanwhile, they became a team of 20, with revenue of INR12m. The shift from no rent to a rented space made DTI slip to break-even. However, after two years, they moved into a smaller space and it coincided with the COVID-19 outbreak. Although the backlog orders were processed during the first quarter of 2020–2021, the business for the next quarter was affected. Social distancing norms created a shift in the way of doing business, which was a boon for a designing company like DTI. Now, the task before this self-made woman entrepreneur was to formulate strategies to scale up the business.

Expected learning outcomes

After analysing the case, the students will be able to: i. Value the contribution of women entrepreneurs towards the economy. ii. Examine the motivational factors and challenges of women entrepreneurs. iii. Understand the importance of networking. iv. Appraise the socio-cultural factors in a patriarchal society and their impact on the work-life balance of a woman entrepreneur. v. Appreciate the interactive leadership style of women entrepreneurs. vi. Formulate strategies to scale up the business.

Abstract

Purpose

The purpose of this paper is to examine the mimicking behaviour of institutional investors in the stock market.

Design/methodology/approach

The study focusses on examining the herding behaviour among institutional investors in the stock market by considering the bulk and block trade on the constituent NIFTY 50 index during the period 2005–2015 using Lakonishok–Schleifer–Vishny (1992) model. The study also aims to find out whether their herding behaviour is intentional or unintentional in nature.

Findings

The findings of the study showed no sign of herding behaviour in the market; out of 50 constituent stocks of NIFTY 50, there was significant herding in 15 stocks, with buy herding in 11 stocks and sell herding in four stocks, and remaining 35 stocks were totally free from herding behaviour. In addition, the results proved that the herding behaviour observed on the stocks is of unintentional in nature.

Research limitations/implications

Present study is limited to the use of constituent stocks of the Benchmarking Index NIFTY 50.

Originality/value

This study is the first attempt to investigate the herding behaviour of institutional investors in the market using bulk and block trade and also to explore their intent in herding behaviour.

Abstract

Purpose

The purpose of this paper is to examine industry herding among the institutional investors and to find whether their herding behaviour is intentional or unintentional.

Design/methodology/approach

The study uses Lakonishok et al. (1992) model to examine the presence of industry herding behaviour among institutional investors. To determine whether the herding observed is intentional or unintentional, herding measure is regressed with volatility, volume, beta and return. The period of the study is from 1 April 2005-31 March 2015.

Findings

The findings of the study showed that though institutional investors have herding tendency towards most of the industries, in the overall period industry herding was not significant. The herding found in some industrial sectors was linked to economic performance of those sectors in India during the period of study and hence the herding was unintentional in nature.

Research limitations/implications

This is the first attempt to study industry herding among institutional investors and their intent in Indian market ever since the country opened its market to foreign investors in a big way. Present study is limited to the use of only bulk/block data instead of the entire trading data for the period.

Originality/value

This study is the first attempt to investigate industry herding behaviour of institutional investors in the market using their bulk and block trading data. The herding observed in well performing industries has been shown to be unintentional and hence rational. The results indicate that the entry of big institutional investors, including foreign institutions into the Indian market has not destabilised the market by irrational herding.

Abstract

Purpose

Multiple-input multiple-output (MIMO) combined with multi-user massive MIMO has been a well-known approach for high spectral efficiency in wideband systems, and it was targeted to detect the MIMO signals. The increasing data rates with multiple antennas and multiple users that share the communication channel simultaneously lead to higher capacity requirements and increased complexity. Thus, different detection algorithms were developed for the Massive MIMO.

Design/methodology/approach

This paper focuses on the various literature analyzes on various detection algorithms and techniques for MIMO detectors. Here, it reviews several research papers and exhibits the significance of each detection method.

Findings

This paper provides the details of the performance analysis of the MIMO detectors and reveals the best value in the case of each performance measure. Finally, it widens the research issues that can be useful for future researchers to be accomplished in MIMO massive detectors

Originality/value

This paper has presented a detailed review of the detection of massive MIMO on different algorithms and techniques. The survey mainly focuses on different types of channels used in MIMO detections, the number of antennas used in transmitting signals from the source to destination, and vice-versa. The performance measures and the best performance of each of the detectors are described.

Abstract

Purpose

The purpose of the study is to highlight the potential of the sensor based smartphone in assessing the covid-19 cases. Coronavirus disease 2019 (COVID-19) is a noxious pandemic affecting the respiratory system of the human and leading to the severe acute respiratory syndrome, sometimes causing death. COVID-19 is a highly transmittable disease that spreads from an infected person to others. In this regard, a smart device is required to monitor the COVID-19 infected patients by which widespread pandemic can be reduced.

Design/methodology/approach

In this paper, an electrochemical sensor-enabled smartphone has been developed to assess the COVID-19 infected patients. The data-enabled smartphone uses the Internet of Things (IoT) to share the details with the other devices. The electrochemical sensor enables the smartphone to evaluate the ribonucleic acid (RNA) of COVID-19 without the nucleic acid and feeds the data into the data server by using a smartphone.

Findings

The obtained result identifies the infected person by using the portable electrochemical sensor-enabled smartphone, and the data is feed into the data server using the IoT. Whenever an infected person moves outside the restricted zone, the data server gives information to the concerned department.

Originality/value

The developed electrochemical sensor-enabled smartphone gives an accuracy of 81% in assessing the COVID-19 cases. Thus, through the developed approach, a COVID-19 infected person can be identified and the spread can be minimized.

Abstract

This chapter analyzes the role of grassroots organizations as natural helping systems for women’s empowerment in the rural areas of central Mexico. For almost three decades, productive projects have been the preferred strategy by the Mexican government in order to alleviate extreme poverty and promote women’s empowerment. Even if the impact of productive projects on women’s empowerment has been limited, grassroots organizations are created in order to have access to financial resources that have promoted the collective dimension of women’s empowerment. Through semi-structured interviews and participatory observation, this study retrieves the experience of women’s leadership, frustrated by changing public policy, local corruption, and political use of the social policy. In those difficult circumstances, grassroots organizations are fundamental tools for women’s well-being as they promote a specific understanding of empowerment, where family, community, and relatedness are values more important than competition and individualistic achievements.

Abstract

Purpose

The purpose of this paper is to identify the “selling points” for Open University Malaysia (OUM) to be used in its marketing activities and the “critical points” that OUM should focus on for further improvements in providing its services to its students. These selling and critical points are derived from the analysis of the importance and satisfaction data collected from OUM’s postgraduate students.

Design/methodology/approach

This study employs a two-dimensional, i.e., Importance-Satisfaction Survey which consists of 47 items, categorized under eight dimensions. Items are phrased as positive statements and students are asked to indicate how important it is to them using a seven-point Likert scale ranging from not at all important (1) to very important (7). They are then asked to rate their level of satisfaction, using the same scale from very dissatisfied (1) to very satisfied (7). A total of 709 postgraduate students responses were used in this study. A multiple regression analysis was conducted to explain the relationship between the dependent variable, overall satisfaction and eight independent variables. The “selling points” and “critical points” are determined by combining the quadrant and gap analyses. The “selling point” items are the high-importance-high-satisfaction (HIHS) items with relatively small gap scores while the “critical points” are those in the high-importance-low-satisfaction and HIHS quadrants with relatively large gap scores.

Findings

The overall results of the Importance-Satisfaction Survey showed that the postgraduate students are generally satisfied with OUM’s programmes and services. The multiple regression analysis of all dimensions against overall satisfaction as the dependent variable showed that the five dimensions of facilitator, curriculum, faculty, support services and learning centre account for 75.7 per cent of the variation in overall satisfaction. The selling points include: the learning management system (MyVLE), online registration, course contents, modules and facilitators. The critical points include those related to facilitator interaction and feedback, students’ sense of connectedness with the faculty staff, timely responses to enquiries and complaints and accessibility to digital library and learning centre staff.

Practical implications

Importance-Satisfaction Surveys can be used to help an institution to identify the services and facilities that can be marketed and also those that need to be improved in order to better meet its students’ expectations.

Originality/value

While many similar studies had been conducted elsewhere, this study had identified the “selling points” and “critical points” which are unique to OUM. In addition, most previous studies were focused on conventional institutions, carried out in many different countries with differing learning environments and cultures.

Abstract

Purpose

The COVID-19 epidemic has brought attention to the variables that influence the mental health of health workers who are entrusted with nursing individuals. Despite the fact that many articles have examined the effects of social media usage on mental health, there is a lack of research synthesizing learning from this body of research. The purpose of this study is to use text mining and citation-based bibliometric analysis to conduct a detailed review of extant literature on health workers’ mental health and social networking habits.

Design/methodology/approach

This study conducts a full-text analysis of 36 articles selected on health workers' mental health and social media using text-mining techniques in R programming and a bibliometric citation analysis of 183 papers from the Scopus database in VOS viewer software. But the limitations of the methods used in this study are that the bibliometric analysis was limited to the Scopus database because the VOS viewer program did not support any other database and the text-mining approach caused the natural processing redundancy.

Findings

The bibliometric analysis reveals the thematic networks that exist in the literature of health workers’ mental health and social networking. The findings from text mining identified ten topic models, which helped to find the related papers classified in ten different groups and are provided alongside a summary of the published research and a list of the primary authors with posterior probability through Latent Dirichlet Allocation.

Originality/value

To the best of the authors’ knowledge, this is the first hybrid review, combining text mining and bibliometric review, on health workers’ mental health where social networking plays a moderating role. This paper critically provides an overview of the impact of social networking on health workers' mental health, presents the most important and frequent topics, introduces the scientific visualization of articles published in the Scopus database and suggests further research avenues. These findings are important for academics, health practitioners and medical specialists interested in learning how to better support the mental health of health workers using social media.
