Abstract

Purpose

As the normality concept for frictional dilatant material has a serious drawback, the key feature in this numerical study is that the material here is characterized by elastic-viscoplastic constitutive relation with plastic non-normality effect for two different hardness functions. The paper aims to discuss this issue.

Design/methodology/approach

Quasi-static, mode I plane strain crack tip fields have been investigated for a plastically compressible isotropic hardening–softening–hardening material under small-scale yielding conditions. Finite deformation, finite element calculations are carried out in front of the crack with a blunt notch. For comparison purpose a few results of a hardening material are also provided.

Findings

The present numerical calculations show that crack tip deformation and the field quantities near the tip significantly depend on the combination of plastic compressibility and slope of the hardness function. Furthermore, the consideration of plastic non-normality flow rule makes the crack tip deformation as well as the field quantities significantly different as compared to those results when the constitutive equation exhibits plastic normality.

Originality/value

To the best of the authors’ knowledge, analyses, related to the constitutive relation exhibiting plastic non-normality in the context of plastic compressibility and softening (or softening hardening) on the near tip fields, are not explored in the literature.

Abstract

Purpose

The consumption of news from social media is the new trend, still news channels are the authentic source to transmit relevant news to audiences. Social media has gradually left an impact on the audience but the news channels have upgraded and providing various news services online on social media websites. The present study aims to study the type of news videos uploaded by the top five Hindi TV news channels on their YouTube channels with an aim to see which type of videos spark interest for YouTube viewers.

Design/methodology/approach

By applying the techniques of content analysis, sentiment analysis and text mining the study aims to measure the average sentiments, top words and the trend of selected popular terms in the comments on uploaded news videos by the top five Hindi news channels over a period of one year.

Findings

Results of the study indicate that the news channels are uploading more news videos about crime and investigation, politics, health and protests while uploading fewer news videos covering travel, science and technology, and religion. While the viewers of the participating news channels are more interested in giving their thoughts or opinions in the form of comments on news videos concerning crime, politics, protests and health or that these videos inspire conversation on YouTube.

Research limitations/implications

The findings might be of interest to content managers of news channels to understand the interest of their audience.

Originality/value

The study's distinctiveness resides in the approach utilised to collect data and analyse the results in order to better understand the online behaviour of news channel audiences.

Abstract

Purpose

Increased competition among different retail formats has led mall managers to focus on mall promotional activities to attract shoppers to malls. The purpose of this paper is to understand Indian mall retailers views on mall events and its role in improving traffic, sales and mall image.

Design/methodology/approach

The current study used a qualitative to decipher mall retailers’ views regarding mall events. In total, 36 in-depth interviews of mall retailers across 13 metropolitan and non-metropolitan cities (Tier-I and Tier-II) were conducted to develop a comprehensive understanding of mall events organized by Indian mall managers.

Findings

The findings revealed that mall events were categorized under six different types: product launch events, events organized to promote the social cause, commemorate festivals, celebrity nights, events organized by retailers in malls and theme events. There were differences in the nature of events used by malls in bigger and smaller cities across India. The nature of mall events varied according to regional, cultural and lifestyle factors across the country.

Research limitations/implications

Mall managers can use the insights from the study on mall events for segmenting and targeting strategies. The different types of mall events can be used for improving footfall, sales and mall image. The study findings employ a grounded theory approach to understand mall retailers’ views on mall events. Future research can be directed toward understanding mall managers’ and consumers’ opinions about the relevance of mall events in improving footfall and profitability of malls.

Originality/value

Extant research has looked at mall events, their role and efficacy in a consolidated manner. The current study attempts to segregate the events organized by mall management into distinct categories and provide linkages of these categories concerning mall image and traffic.

Abstract

Learning outcomes

Teaching objective 1: To flourish and explore the current business model to get socioeconomic benefits from organic farming compared to conventional farming; in the context of hill farming. Teaching objective 2: To explore and design innovative entrepreneurship opportunities in the field of organic farming and how these opportunities can be seized by using managerial skills. Teaching objective 3: To analyze the economic benefits of organic farming compared to conventional farming.

Case overview/synopsis

Manj Gaon is a small village in the Tehri Garhwal district of Uttarakhand. This village serves as the Uttarakhand Organic Commodity Board’s training facility. Organic farming was the primary source of income for farmers in the late 1970s, but the Green Revolution in India had a negative impact on agriculture, the environment and the economy of the country. After the Green Revolution, the agriculture sector was completely dominated by conventional farming, and the use of chemical fertilizers, pesticides and insecticides affected the village to some extent. But farmers like Bhagchand Ramola paved the way for other farmers to grow and shine through organic farming. The organic farming model developed by Ramola was helping farmers and society in several aspects, such as the economy, health and the environment. A self-developed organic farming model had been generating fair revenue for the farmers and uplifting their socioeconomic status as compared to conventional farming. Complete adoption of organic farming in the village requires an analysis in terms of sustainable economic growth. However, there was a certain dilemma that was stifling the growth of the newly adopted business model because farmers were dependent only on Japanese buyers and input providers. So, there was a huge need to tie up with other consulates across the country. Secondly, expanding a business model requires more input and output in terms of manpower and revenue, so persuading conventional farmers to adopt the organic farming model was quite a challenge for Ramola.

Abstract

Purpose

This study has been carried out in dairy product manufacturing industry of Northern India to judge the significance of supply chain strategies viz. cost reduction and optimization strategies toward performance improvement and mediator effect of strength and opportunity between strategies and performance parameters.

Design/methodology/approach

Questionnaire survey has been performed to justify their role toward performance improvement. Structural equation modeling, descriptive statistics, hierarchical regression and clusters and partial least square-structural equation modeling has been applied for ascertain the benefits occurred.

Findings

Results indicated that strength (success factors of strength identified from literature) is the significant mediator than opportunity (success factors) for enhancing performance of organization. Small incremental improvements and 5S activities are highly important cost reduction strategies for enhancing performance of supply chain strategies. Supply chain strategies significantly improve the quality of milk in the industry under study. The customer has got high-quality product after implementing supply chain strategies. Right-time delivery of product is only possible if failure modes are analyzed thoroughly. Reliability of performance parameters is 88% which signifies that high benefits are achieved by implementing cost reduction and cost optimization strategies of supply chain concept. Processing of milk is significantly improved after taking combined effect of processing and delivery of product.

Originality/value

This paper helps both academics and managers to gain a better understanding of this question by considering the role of supply chain strategies implementation practically through a standard procedure.

Abstract

Purpose

Although common throughout the world, little is known about the mechanism by which nepotism is associated with employee outcomes. Drawing from social exchange theory, this study examines whether fear-based silence mediates the relationship between nepotism with employee workplace withdrawal and career satisfaction. In addition, whether gender moderates the relationship between nepotism and fear-based silence is also examined.

Design/methodology/approach

Two time-lagged surveys of 330 employees in the Indian banking sector were completed.

Findings

As hypothesized, nepotism was positively related to fear-based silence and employee workplace withdrawal; it was negatively related to career satisfaction. Fear-based silence partially mediated the relationships of nepotism with workplace withdraw and career satisfaction. Gender moderated the relationship between nepotism and fear-based silence.

Practical implications

This study shows the negative impact of nepotism on employee outcomes and suggests means for reducing its prevalence in organizations.

Originality/value

This is the first study to examine fear-based silence as a mediator of nepotism’s relationship with employee workplace withdrawal and career satisfaction. It also answers repeated calls for more research on fear-based silence and its antecedents.

Abstract

Purpose

The purpose of this study is to assess the effect of chicken breeds on quality characteristics of meat nuggets.

Design/methodology/approach

The formulation of meat nuggets prepared from meat of Cobb-400, Vanraja, Aseel and Kadaknath separately consisted of 60 per cent lean meat. The emulsion was prepared by standard method and moulded into nuggets. Cooking was performed under pressure (120°C/15 Psi for 30 min).

Findings

Emulsion and cooked nuggets both showed no significant differences in pH values among the breeds. Higher moisture and fat content was observed in emulsion and nuggets prepared from Cobb-400, while respective protein and ash was maximum in Kadaknath and Vanraja meat-based emulsions and nuggets. The per cent emulsion stability (87.04 ± 0.45) and cooking yield (85.24 ± 0.06) was reported highest in Cobb-400, which indicates the better water holding capacity and suitability of Cobb-400 meat for the development of nuggets at six weeks of age. The mean sensory scores for colour and appearance (7.12 ± 0.28), as well as flavour (7.00 ± 0.04), were significantly (p < 0.05) higher in Cobb-400 nuggets and lowest in Kadaknath (6.21 ± 0.03 and 6.65 ± 0.06). However, no significant differences were noticed in other sensory attributes among treatments.

Research limitations/implications

The fatty acid and amino acid profile analysis may be helpful to understand the original nutritional difference in prepared nuggets.

Practical implications

The study will be off immense help in optimum utilization of meat of locally available chicken breeds for breed-specific and cost-effective product formulations.

Social implications

The products will be acceptable to all commodities because it is made up of chicken meat.

Originality/value

The effect of chicken breeds on meat nuggets is relatively new aspect and essential to establish suitability of meat of locally available chicken breeds for product development.

Abstract

Learning outcomes

The learning objectives of this case study are based on Bloom’s taxonomy. Upon completion of the case study discussion and exercises, successful students will be able to design a leadership transition and succession plan for non-profit organisations; identify and evaluate critical skills and competencies required in leadership positions; and frame expectations and responsibilities for new and departing executives.

Case overview/synopsis

Apar Gupta co-founded Internet Freedom Foundation (IFF), a digital rights organisation born out of SaveTheInternet – Net Neutrality movement of 2015, credited for urging the Telecom Regulatory Authority of India to uphold net neutrality in India. And ban zero-cost internet services that promoted data discrimination in the country. After working on and winning the net neutrality movement, Gupta identified many areas in technology where democratic rights had not been identified or were yet to be clearly defined (like in the case of net neutrality). There was also a service gap between the existing internet volunteer groups and digital rights organisations, which could IFF fill. This was to provide objective clarity, stakeholder identification, handle policy discussions and, most importantly, arrange resources to support movements over the long term. This prompted him to co-found IFF in 2017, which he later joined as a full-time executive director in 2018. IFF worked at the intersection of technology, democratic rights and government policies and was comparable to some global organisations, such as the Electronic Frontier Foundation in the USA and the Open Rights Group in the UK. Still, none existed in India at the time. After four years as a full-time executive director in 2022, he was convinced that it was finally time for him to act on the pre-defined strategic departure plan and work towards succession for the executive director position. While there were visible gaps in the system, Gupta’s leadership design and plans had helped IFF overcome existential challenges in the past. Also, while digital rights were still at a nascent stage in emerging economies, under Gupta’s leadership, IFF had delivered unmatched value to its beneficiaries in the world’s biggest digital consumer market. However, constant changes in regulations and continuing financial constraints made him nervous about the outcomes of the succession and the overall sustainability of IFF. Gupta wanted to ensure that this phased transition from executive director after two years and then trustee manager after the next four years are carefully communicated to reduce the likelihood of attrition and loss of trust.

Being the co-founder and the first and only executive director IFF had seen, the organisation would also require significant skill and competency mapping to identify the new executive leadership. But with no clear internal successor in sight, the non-profit trust would also need a successor who not only was competent but also would share a passion for the type of work done by IFF, its unique delivery mode, and also would openly inherit its position in society. The other alternative strategic routes present were to look for dual leadership or interim leadership, but then there could be concerns about Gupta’s influence overshadowing any such alternative.

In the case scenario, IFF is planning for succession while navigating the organisation through financial constraints and constant regulatory changes to ensure long- and short-term sustainability.

Complexity academic level

The case study has been written to gain insights into departure-defined successive planning in non-profit organisations. The case study can also be used to gain insights into innovative start-ups and innovative non-profit start-ups, as digital rights are still at nascent stages in emerging markets. The case study will be valuable for courses such as human resource management, strategic human resource management, social entrepreneurial leadership, leadership development, start-up environment, innovation and entrepreneurship, public policy, development studies, cyber security and information technology. The case study also allows students and young professionals to take the perspective of an innovative start-up founder and design a departure-defined succession plan. The case study can also be useful for senior students wanting to undertake an entrepreneurial career by starting or joining a non-profit organisation. While the case study is suitable for postgraduate- and executive-level courses, it can also be used for conducting entrepreneurial workshops and skill training.

Abstract

Purpose

The purpose of this paper is to develop and empirically validate items on social isolation. The comprehensive literature review of existing studies on the measures of social isolation, loneliness and the related construct was conducted. The paper seeks to conceptualize, validate and present items to measure social isolation.

Design/methodology/approach

The paper is based on theoretical and empirical investigation of the measures of social isolation, loneliness and related constructs such as social others, social loneliness and feeling of sociability. The items were generated through theoretical exploration of previous literature and later modified. The author examined the items through exploratory factor analysis, confirmatory factor analysis and further checked for external criterion validity. Data collected from 128 individuals, in India, were examined to design and validate the scale.

Findings

The finding of the paper is a ten-item social isolation scale. Using structural equation modeling, we have found extraversion and well-being significantly associated with final items in the present study, confirming the external quality of the scale.

Practical implications

Organizations may benefit by close examination of the presence of social isolation in employees along with providing support and assistance to employees so as to reduce negative consequences of social isolation and can address the well-being of the employee.

Originality/value

There is a dearth of developed and validated measures of social isolation in the literature. The study reveals the conceptualization and empirical validation of measures of social isolation in the Indian context so that researchers can move forward to develop theories on social isolation.

Abstract

Purpose

The two-dimensional deformation of a homogeneous, thermally conducting, monoclinic material has been studied by using Laplace and Fourier transforms technique. A linear temperature ramping function is used to more realistically model: thermal loading of the half-space surface. The general solution obtained is applied to a specific problem of a half-space subjected to ramp-type heating and loading. The displacements, stresses and temperature distribution so obtained in the physical domain are computed numerically and illustrated graphically. The comparison for Lord-Shulman (L-S), Green and Lindsay (G–L), Green and Naghdi (G–N) and Chandrasekharaiah and Tzou (CTU) theories have been shown graphically to estimate the effect of ramping parameter of heating for an insulated and temperature gradient boundaries.

Design/methodology/approach

The design of the study is eigenvalue approach

Findings

Homogeneous, thermally conducting monoclinic material has been taken under consideration to study the effect of linear temperature ramping parameter on temperature and normal displacement field. It is observed that magnitude of field quantities is large near the point of application of source for the non-dimensional values of time in all the four models. The numerical values for the field quantities are computed graphically for a wide range of values of finite pulse rise-time in the two situations t0 < t, t0 > t for generalized thermoelasticity theories.

Originality/value

(1) Governing equations for homogeneous, t0 thermally conducting, monoclinic material are described and solved. (2) Eigen value approach is used to solve the problem. (3) The effect of ramping parameter of heating has been studied for various models of the thermoelasticity to show the comparision between them.
