Abstract

Purpose

The purpose of this paper is to present a numerical approach for investigating different phenomena during multiple liquid drop impact on air‐water interface.

Design/methodology/approach

The authors have used the coupled level‐set and volume‐of‐fluid (CLSVOF) method to explore the different phenomena during multi‐drop impact on liquid‐liquid interface. Complete numerical simulation is performed for two‐dimensional incompressible flow, which is described in axisymmetric coordinates.

Findings

During drop pair impact at very low impact velocities, the process of partial coalescence is observed where the process of pinch off is different than single drop impact. At higher impact velocities, phenomena such as bubble entrapment are observed.

Originality/value

In this paper, a new approach has been developed to simulate consecutive drop impact on a liquid pool.

Abstract

Purpose

The purpose of this paper is to investigate the influence of forced, in-line oscillation of a circular cylinder on an incoming incompressible flow field at different Reynolds numbers.

Design/methodology/approach

A space-time finite element approach is employed to model the flow around an oscillating cylinder.

Findings

The results show that two (2S), four (2P, two pair) and three vortices (P+S, one pair and one single) are shed in each cycle. In addition, a 2P o mode is also observed, which is similar to the 2P mode but the vortices of the 2P o mode differ in strength. The 2P mode of vortex shedding is observed along the entire wake of the flow field and 2P o mode in the far wake. In some cases, the vortex street is transformed as it travels towards the exit to produce new patterns. One such pattern is observed for the first time in the present work, which is referred to as 2P o* mode. The drag and lift coefficients observed are perfectly periodic at a Reynolds number of 200 and they reach a chaotic pattern as the Reynolds number is increased to a value of 350.

Originality/value

Originality of the paper lies in the observation of 2P vortex shedding mode or its variants in the downstream of the cylinder.

Abstract

Risk factors for population relocation as a result of severe catastrophes are increasing on a global scale. The frequency of catastrophic weather events is rising, infrastructure is getting older, the population is expanding, and urbanization is increasing. This study explores the influencing factors of livelihood, vulnerability, and livelihood resilience of climate-induced displaced people in developing countries, particularly in South Asia. A mixed-method approach comprising a systematic review and a narrative review has been applied in this study. A systematic review guided by PRISMA has been used to identify the relevant documents and the extracted information has been described through a narrative review approach. This study reveals that climate-induced displaced people are generally vulnerable to maintaining their livelihood, but there are a few exceptional cases where displaced people could diversify their livelihood strategies. The major influencing factors of their livelihoods are riverbank erosion, loss of assets and properties, food insecurity, seasonal hunger, low access to finance, and low job opportunity. This study argues that climate-displaced people have a long struggle to enhance their livelihood resilience, but it is a challenging task for them, particularly at the household level. The major influencing indicators under adaptive, absorptive, and transformative capacities of livelihood resilience are income and food access, agricultural and non-agricultural assets, sensitivity, climate variability and hazards, basic services, social safety nets, and institutional participation. Appropriate governance in the structural and non-structural transformation of livelihood capitals can enhance the livelihood resilience of climate-induced displaced households. In the case of Bangladesh, the coastal and Riverine Island communities are the key victims of climate-induced hazards, so they migrated frequently to reduce their vulnerability and enhance livelihood resilience. The study recommends ensuring transparency and accountability, proper coordination among stakeholders for promoting the resettlement, disaster-resilient housing and infrastructure, and Khas land (government-owned land) to the displaced people can enhance their livelihood resilience.

Abstract

Purpose

“Know thyself” helps one to decide the career goal of his/her life and enables one to become self-concordant. In this context, the present work aims to discern the childhood interests (CI) of the HR professionals vis-à-vis their relevance.

Design/methodology/approach

The current study is grounded on two theoretical perspectives such as Socio-Cognitive Career Theory (SCCT) and Holland Theory of Career Choice (HTCC). In this regard, a mixed methodology has been applied. The research has been carried out in two phases. In the first phase, a focused group of experienced HR professionals was interviewed to understand their CI and their relevance to the HR profession through a qualitative analysis method such as narrative analysis. In the second phase, an Intuitionistic Fuzzy Number-based Full Consistency Method (FUCOM) is applied to find out the dominant CI based on the ratings given by 423 Indian HR professionals.

Findings

All professionals agreed that their CI have helped them perform in their profession. The research identifies five themes or main attributes of personality: Creative (Aesthetic-Non Verbal/Cultural), Communicative (Verbal/ Expressive Activities), People friendliness (Social Contribution), Socially Inclusive (Sociological leadership interest) and Physical Activity (Kinesthetic interests) with 24 subattributes (i.e. childhood interests). It is found that intrinsic interests in societal contributions have been a dominant feature since the childhood days of HR professionals. In all cases, FUCOM shows a very small DFC value <0.00005.

Practical implications

The research provides an important direction to the decision-makers for policy making and aspiring professionals an essential impetus to career planning.

Originality/value

This study is a rare one to discern CI using a mixed methodology for Indian HR professionals.

Abstract

Purpose

The purpose of this study is to examine the pre-training and post-training variables influencing employee training effectiveness in the banking industry in this era of the digital age.

Design/methodology/approach

This study adopted a cross-sectional research design and a structured questionnaire to survey the participants (i.e., bank employees) (n = 702) for data collection. The data gathered from the surveyed respondents were analyzed using the Partial Least Square to Structural Equation Modeling (PLS-SEM) approach to test the proposed hypotheses.

Findings

The research findings suggest a significant influence of pre-training (i.e., training environment, trainer quality) and post-training (i.e., trainee motivation, trainee self-efficacy, and authentic leadership practices) factors towards the bank's staff training effectiveness in this era of digital age.

Originality/value

The research is one of the pioneer attempts on training effectiveness that significantly open opportunity for financial institutions such as banks to meet the challenge of the fourth industrial revolution from a developing country perspective. The current study also contributes to the extension of the theoretical and managerial doctrine in terms of the relationship among the pre-and post-training factors to enhance training effectiveness under the scope of the financial sector's employees to manage human resources and their development in the digital age.

Abstract

Purpose

Mud architecture as one of the expressions of vernacular architecture illustrates the success of indigenous knowledge of traditional communities. Due to the pressure of industrialization, urbanization and globalization, the trend of using non-traditional measures guided by the Western-Euro-centric knowledge and technologies considers the traditional practices as expressions of backward past, under-development and poverty. Though mud as a building material is usually assumed as a fragile and ephemeral material that cannot survive against natural hazards, the surviving traditional mud buildings are needed to be investigated to know their performances during and after different types of natural hazard incidents.

Design/methodology/approach

This paper intends to study the available cases of mud architecture of Chattogram, Bangladesh to trace the history of their survival despite of experiencing multiple natural hazards and to understand their status and prospect of resisting hazards. Three individual homesteads are chosen as cases for conducting physical survey as well as engaging inhabitants and local masons of the locality in semi-structured interviews in a story telling mode to know the construction process and histories of experiencing natural hazards. Available literatures are reviewed, and experts are interviewed to understand the causes of their performances and possible ways to improve the quality.

Findings

Collected information on mud architecture demonstrates their quality of surviving against many natural challenges and this hazard-resilient quality can be enhanced through using contemporary building technologies and materials, promising to co-exist with the global trend.

Originality/value

This study as an attempt to reinvent the vernacular architectural heritage endorses the need of appreciating indigenous knowledge for enhancing community resilience against natural hazards.

Abstract

Purpose

This study aims to assess the biodiversity of the study area and estimate the carbon stock of two dry deciduous forest ranges of Banka Forest Division, Bihar, India.

Design/methodology/approach

The phytosociological analysis was performed and C stock estimation based on volume determination through nondestructive methods was done.

Findings

Phytosociological analysis found total 18,888 [14,893 < 10 cm (diameter at breast height) dbh] and 2,855 (1,783 < 10 cm dbh) individuals at Banka and Bounsi range with basal area of 181,035.00 cm2 and 32,743.76 cm2, respectively. Importance value index was highest for Shorea robusta in both the ranges. Species diversity index and dominance index, 1.89 and 1.017 at Banka and 1.99 and 5.600 at Bounsi indicated the prevalence of biotic pressure. Decreased dbh and tree height resulted in a lowered growing stock volume as 59,140.40 cm3 ha−1 (Banka) and 71,306.37 cm3 ha−1 (Bounsi). Total C stock at Banka and Bounsi range was 51.8 t ha-1 and 12.56 t ha−1, respectively where the highest C stock is recorded for Shorea robusta in both the ranges (9.8 t ha−1 and 2.54 t ha-1, respectively). A positive correlation between volume, total biomass and basal area of tree species with C stock was observed. R2 value for Banka range was 0.9269 (volume-C stock), 1 (total biomass-C stock) and 0.647 (basal area-C stock). Strong positive correlation was also established at Bounsi range with R2 value of 1. Considering the total forest area enumerated, C sequestration potential was about 194.25 t CO2 (Banka) and 45.9 t CO2 (Bounsi). The valuation of C stock was therefore US$2,525.25 (Banka) and US$596.70 (Bounsi).

Practical implications

The research found the potentiality of the study area to sequester carbon. However, for future, the degraded areas would require intervention of management strategies for restoration of degraded lands and protection of planted trees to increase the carbon sequestration potential of the area.

Originality/value

Present study is the first attempt to assess the phytosociology and estimate the regulatory services of forest with respect to biomass and carbon stock estimation for the Banka forest division of Bihar.

Abstract

Purpose: This chapter aims to evaluate the significant impact of Gandhian values on sustainable consumption behaviour (SCB) by applying the value-attitude-behaviour (VAB) framework. This chapter contributes by incorporating Gandhian values as one influencing factor for SCB.

Need for the Study: Values are considered as guiding principles in people’s lives. Studies suggest that values and other social and psychological factors can be vital in determining consumers’ behaviour towards sustainable consumption. There needs to be more empirical research on consumer behaviour facets of sustainable consumption for markets in India.

Methodology: The study uses partial least square structural equation modelling to empirically test proposed hypotheses and the research model of the relationship. The study results are based on data collected by administering a survey through a questionnaire confined to India.

Findings: The results indicated that Gandhian values, attitude, and sustainable consumption intention significantly influence SCB. Intention acts as a mediator between both outward and inward environmental attitudes and behaviour. The study provides directions for further research.

Practical Implications: This research study is helpful for researchers, marketers, and policymakers.

Abstract

Purpose

The purpose of this paper is to shed light on the relationship between organizational commitment (OC) and organizational citizenship behavior (OCB) as mediated by employee engagement (EE). The impact of different facets of OC (affective, continuance and normative) and EE (alignment, affectiveness and action-orientation) is examined with respect to OCB.

Design/methodology/approach

Insights from the literature underpin the hypotheses on how EE mediates the relationship between OC and OCB. Primary data using survey questionnaire were collected from 881 permanent employees of Delhi Metro Rail Corporation (DMRC) in India. Hayes' model 4 has been used for the mediation analysis.

Findings

The analyses show that only one facet of OC- affective commitment and the alignment and action-orientation dimensions of EE positively affect OCB. The relationship between OC and OCB is fully mediated by EE.

Practical implications

The results imply that engaging employees is pivotal for effectively fostering citizenship behavior among employees. Organizations should be willing to implement strategies and interventions which enhance the emotional experience of employees to foster a sense of belongingness with the organization and engage them.

Originality/value

The paper draws on a unique data set of a prestigious organization in India to provide insights with substantial degree of generalizability into the relationship between OC, OCB and EE, whilst applying a comprehensive definition of these constructs. It is the first study to examine the inter-relationship among different facets of these constructs.

Abstract

Purpose

The momentum of globalization has helped the organization to gain new insights into the domain of human resources (HRs). The changing nature of work has affected the coherence of the workplaces. Today, it is essential to preserve and nurture the cognitive and creative abilities of the diverse group of employees so that concrete outcomes and actions can be achieved. Human resource planning (HRP) is one of the processes that facilitate the development of employees and the integration of their individual goals with the business plans. This paper aims to produce useful predictions and unprecedented direction to boost organizational performance amidst cyclical business fluctuations. The innovative HRP programs minimize the dysfunctional aspects of employee handling through proper assessment of their skills and abilities. This inclusive approach initiates a sustainable journey for the firm and heightens its competitive edge.

Design/methodology/approach

A descriptive study has been conducted through a structured questionnaire. Primary data were collected from respondents working in the HR department of different manufacturing companies in the state of West Bengal, India. A multistage sampling technique has been used. Data analysis has been conducted through exploratory and confirmatory factor analysis. Through structural equation modeling, the researchers examined a series of dependence relationships simultaneously and represented unobserved concepts.

Findings

The current study ratifies the overall model and reflects that the HRP activities, namely, retention plan, professional training and development, job analysis and design, succession planning and redeployment plan vitalizes the performance of the firm. A recruitment plan has a negative and non-significant impact on the functional performance of the organization. Succession planning practices immensely affect the firm’s competitive edge followed by the retention plans. The results also uphold that the efficacious performance of the firm brings in strategic sustainability for it.

Practical Implications

HRP activities sufficiently address the HR concerns facilitating the organization to coalesce the needs of the employees and the business. It helps to adopt a long term perspective to foster productivity, innovation and quality. It encourages employees to believe in their competencies to deliver their best. Such practices involve the workforce; coordinate their efforts to contribute meaningfully in this intricate business network. Thus, HRP practices drive to accomplish challenging tasks, focus on creative work-related projects, enhances an employee’s coping skills and morale to establish strategic sustainability for the firm.

Originality/value

The study sheds light on the fact that in this complex and dynamic business system where the authors find multigenerational workforce, it is essential to nurture the subtle aspects of the employees rather than continuous monitoring and controlling them. HRP activities provide such a platform that maximizes employees’ potential and will to fit into a firm’s business strategy and translate a strategic plan into action. Such practices have the capability to intensify the positive aspects and ideas in an organization.
