Abstract

The scalability of similarity joins is threatened by the unexpected data characteristic of data skewness. This is a pervasive problem in scientific data. Due to skewness, the uneven distribution of attributes occurs, and it can cause a severe load imbalance problem. When database join operations are applied to these datasets, skewness occurs exponentially. All the algorithms developed to date for the implementation of database joins are highly skew sensitive. This paper presents a new approach for handling data-skewness in a character- based string similarity join using the MapReduce framework. In the literature, no such work exists to handle data skewness in character-based string similarity join, although work for set based string similarity joins exists. Proposed work has been divided into three stages, and every stage is further divided into mapper and reducer phases, which are dedicated to a specific task. The first stage is dedicated to finding the length of strings from a dataset. For valid candidate pair generation, MR-Pass Join framework has been suggested in the second stage. MRFA concepts are incorporated for string similarity join, which is named as “MRFA-SSJ” (MapReduce Frequency Adaptive – String Similarity Join) in the third stage which is further divided into four MapReduce phases. Hence, MRFA-SSJ has been proposed to handle skewness in the string similarity join. The experiments have been implemented on three different datasets namely: DBLP, Query log and a real dataset of IP addresses & Cookies by deploying Hadoop framework. The proposed algorithm has been compared with three known algorithms and it has been noticed that all these algorithms fail when data is highly skewed, whereas our proposed method handles highly skewed data without any problem. A set-up of the 15-node cluster has been used in this experiment, and we are following the Zipf distribution law for the analysis of skewness factor. Also, a comparison among existing and proposed techniques has been shown. Existing techniques survived till Zipf factor 0.5 whereas the proposed algorithm survives up to Zipf factor 1. Hence the proposed algorithm is skew insensitive and ensures scalability with a reasonable query processing time for string similarity database join. It also ensures the even distribution of attributes.

Abstract

Purpose

Organizations are increasingly emphasizing inclusive practices to leverage the valuable potential of their human resource. This study seeks to investigate the influence of organizational norms on the experiences of inclusion among women in manufacturing organizations. This study aims to comprehend how gendered perceptions of the ideal worker shape women’s sense of inclusion within the workplace.

Design/methodology/approach

The research adopted a qualitative approach to understand women’s experience of inclusion in the manufacturing workplace. Purposive and snowball sampling techniques were used to conduct semistructured interviews with 52 professionals working in the four manufacturing organizations. These employees were working in different roles as functional managers, human resource managers, diversity officers and female employees. Interviews were analyzed following a three-step coding process. ATLAS.ti software was used to analyze the data. The study draws upon Acker’s theory of “gendered organizations” and West and Zimmerman’s concept of “doing gender” to understand workplace narratives, adapting these theories to the specific context of India.

Findings

This study highlights frequent experiences of exclusion experienced by women in the workplace. This is because of a prevalent culture that prioritizes the ideal worker image within workplace narratives, serving as a significant catalyst for these experiences of exclusion. Additionally, the study underscores how apparently supportive measures, initially appearing beneficial, can inadvertently heighten women’s vulnerability to workplace exclusion.

Originality/value

This study shows how broader national and industrial cultures, which are often male-dominated, can, further reinforce barriers to creating a gender-inclusive workplace. Overall, the study underscores the importance of addressing ideal worker narratives as pivotal steps toward fostering a workplace that is genuinely inclusive for women.

Abstract

Purpose

Many aspects of well-being depend critically on individual-level expenditure and consumption. The Millennium Development Goals include the promotion of gender equality and the empowerment of women, which partly have to do with women’s access to resources within households. Many important questions in labour, public and development economics also hinge on the intra-household distribution of resources. This paper aims to estimate the resource shares within a household in the rural and urban sectors of West Bengal through a collective household model, where each household member has a specific utility function. The sharing rule parameters, that determine the apportionment of resources between members within a household, are estimated in an intra-household collective framework. The analysis is based on a system of log-quadratic Engel curves estimated using the 68th round (2011–2012) household-level consumption expenditure data of the Indian National Sample Survey Office (NSSO) for rural and urban sectors separately for the state of West Bengal.

Design/methodology/approach

The sharing rule parameters (that determine the apportionment of resources between members) within a household are estimated in an intra-household collective framework as suggested by Dunbar et al. (2013). The analysis is based on a Quadratic Almost Ideal Demand System (QUAIDS) estimated using the 68th round (2011–2012) household-level consumption expenditure data of the Indian NSSO.

Findings

In this paper, the authors estimate the sharing rule of total household expenditure between couples in a household in the state of West Bengal. They use a modified version of the QUAIDS and the 68th round (2011–2012) household-level consumer expenditure data provided by the NSSO. From the exercise, it emerges that on an average, the resource shares between husband and wife in a household is about 66:34% in the rural sector and about 60:40% in the urban sector. Based on a classification of households by the distribution of resource shares, where higher resource share for the husband is classified as “Husband dominated” and the reverse as “Wife dominated”, the percentage of “Husband dominated” households is much more in both sectors. This unequal distribution of resources may have far-reaching consequences on allocation of expenditure on the children of the household. The authors leave this exercise as a future project.

Originality/value

This paper is an attempt to estimate the sharing rule for households using NSSO consumption expenditure data.

Abstract

Purpose

Seeks to examine risk assessment of human settlements due to seismo‐tectonic setting of a populated area in the Himalayas, so that mitigation measures may be taken before the next earthquake takes its toll.

Design/methodology/approach

Keeping in view the seismic vulnerability of the Himalayan ranges, an earthquake scenario is considered for the Narendranagar block of Tehri Garhwal District which lies in Seismic Zone IV of the seismic zoning map of India (BIS, 1893‐2002). Damage of MSK Intensity VIII and peak accelerations of 0.25 g are expected here at any time. The hypothetical epicenter is placed near Tapowan at 30°08′10″N and 78° 20′30″E on the crest of the meandering River Ganga, where three large thrusts, viz. Garhwal, Tons Nayar and Krol, congregate. Iso‐acceleration contours plotted for the entire Narendranagar block for earthquakes of magnitude 7.0 and 7.5 are elongated along the main boundary fault.

Findings

Almost 59 percent population of the Narendranagar block was found to be vulnerable to damage associated with higher accelerations of 0.41 g.

Research limitations/implications

The topographic effects influencing the risk of settlements have not been taken into account.

Practical implications

Implications of such an earthquake on housing stock; roads; infrastructure; awareness and time of occurrence are discussed. Strategies are suggested for long‐term earthquake preparedness and short‐term action plan for emergency management.

Originality/value

The methodology evolved can be extended for other Himalayan regions.

Abstract

Purpose – This chapter discusses an education law recently enacted in India – The Right of Children to Free and Compulsary Education – its implementation plan and potential implications, focusing on the teacher labor force composition and the teacher education system. The Right to Education Act specifies acceptable pupil–teacher ratios, levels of teacher vacancy in the school, qualifications required for teacher appointments, and terms and conditions for teacher hiring, among other things.Methodology – This study draws on government documents and reports to conduct a systematic analysis of existing data and historical trends. It generates an understanding of how this policy shapes the demand for teachers, the quality of the existing system, and its ability to respond to these increased demands.Findings – These policy changes intended to increase equity in teacher distribution may in the near future exacerbate inequities in access to quality teachers and teaching across India. The policy creates important and urgent changes in the Indian teacher labor force, and by extension, it demands changes in the Indian teacher education system. But that system may be unprepared to meet these goals. Therefore, the chapter underscores the need for reform in India's teacher education system, if this policy's mandate to provide equal access to quality education to all Indian children is to be fulfilled.Value – This chapter explains and analyzes a recent, large-scale teacher policy reform in a regionally diverse, developing nation with an urgent need to improve the quality of education received by its children.

Abstract

Purpose

The purpose of this paper is to highlight the status and application of automated acquisition in central university libraries in north India. North India is a loosely defined region consisting of northern parts of India. Significantly, all the libraries are having very rich collections of different types of documents.

Design/methodology/approach

Data for the present study have been collected using questionnaire. Interview and observation techniques have also been used to bring more objectivity in the present study. MS-Excel has been used for analysis of the data. Results show that varying levels of progress has been made with respect to implementation of acquisition system in the surveyed libraries.

Findings

Expectations of user community have been increased manifold in the wired world. Furthermore, suggest that the staff morale is boost up in the automated environment.

Research limitations/implications

The study covers select academic libraries of north India. Application of various features of acquisition module is examined in this paper along with the staff perspective about automation. Automation process in these university libraries has been started with the selection of different library management software package in different universities. Notably, all the prominent central universities are located in north India.

Practical implications

The evaluation shed light on the current automation scenario in prominent academic libraries of India.

Social implications

All the surveyed libraries must explore the fullest potentials of all the features available in the software to provide better services. This will help in heading toward and information rich society.

Originality/value

There have been a couple of studies in the past on library automation in academic libraries, but none have intended to cover collection building or acquisition activities in central university libraries of north India.

Abstract

Purpose

The purpose of the paper was to assess the functional properties vegetable gourds & the validated health claims so as to help the future researchers to locate the gaps. However, emphasizing on the scientifically available reports was required to make information available in a nutshell to the health-conscious consumers, as well as the researcher from the area of functional foods and nutrition.

Design/methodology/approach

The paper is a mini-review of scientific findings in different studies on gourd vegetables. The approach to information collection was finding the research gaps and potential areas for future work with a nutritional perspective.

Findings

Ash gourd, bitter gourd and bottle gourd have been extensively studied, and several health benefits and functional components have been reported, while ridge gourd, snake gourd and pointed gourd have been sparsely studied for their therapeutic benefits and the validation thereof; hence, there lies a scope for researchers.

Research limitations/implications

The scarcity of scientific reports compared to the traditional usage and folkloric beliefs was a limitation.

Originality/value

Understanding the nutritional potential of gourd vegetables from scientific reports may influence both the work areas and consumers in the appropriate direction.
