Abstract

Purpose

Participatory wireless sensor networks (PWSN) is an emerging paradigm that leverages existing sensing and communication infrastructures for the sensing task. Various environmental phenomenon – P monitoring applications dealing with noise pollution, road traffic, requiring spatio-temporal data samples of P (to capture its variations and its profile construction) in the region of interest – can be enabled using PWSN. Because of irregular distribution and uncontrollable mobility of people (with mobile phones), and their willingness to participate, complete spatio-temporal (CST) coverage of P may not be ensured. Therefore, unobserved data values must be estimated for CST profile construction of P and presented in this paper.

Design/methodology/approach

In this paper, the estimation of these missing data samples both in spatial and temporal dimension is being discussed, and the paper shows that non-parametric technique – Kernel Regression – provides better estimation compared to parametric regression techniques in PWSN context for spatial estimation. Furthermore, the preliminary results for estimation in temporal dimension have been provided. The deterministic and stochastic approaches toward estimation in the context of PWSN have also been discussed.

Findings

For the task of spatial profile reconstruction, it is shown that non-parametric estimation technique (kernel regression) gives a better estimation of the unobserved data points. In case of temporal estimation, few preliminary techniques have been studied and have shown that further investigations are required to find out best estimation technique(s) which may approximate the missing observations (temporally) with considerably less error.

Originality/value

This study addresses the environmental informatics issues related to deterministic and stochastic approaches using PWSN.

Abstract

Purpose

It has been witnessed that many incidents of crowd evacuation have resulted in catastrophic results, claiming lives of hundreds of people. Most of these incidents were a result of localized herding that eventually turned into global panic. Many crowd evacuation models have been proposed with different aspects of interests. The purpose of this paper is to attempt to bring together many of these aspects to study evacuation dynamics.

Design/methodology/approach

The proposed agent-based model, in a hypothetical physical environment, uses perception maps for routing decisions which are constructed from agents’ personal observations of the surroundings as well as information gathered through distant communication. Communication is governed by a trust model which measures the authenticity of the information being shared. Agents are of two types; emotional and rational. The trust model is combined with a game-theoretic model to resolve conflict of agents’ own type with that of types of agents in the neighborhood.

Findings

Evacuation dynamics in different environmental and exit strategies are evaluated on the basis of reduced herding and evacuation time. Using this integrated information sharing model, agents gain an overall view of the environment, sufficient to select the optimal path towards exits with respect to reduced herding and evacuation time.

Originality/value

The proposed model has been formulated and established using an agent-based simulation integrating important modeling aspects. The paper helps in understanding the interplay between technological and humanistic aspects in smart and pervasive environments.

Abstract

This chapter presents the Smart Irrigation system using the Internet of Things (IoT). IoT Technology is a network of physical objects that are connected with sensors, software, etc. This chapter concludes the project based on the agriculture field that automates the irrigation process and on the agriculture field that automates the irrigation process and solves the challenge of water consumption in those areas. We have developed the system using different sensors like (1) Soil Moisture sensor, which measures the moisture present in the soil, (2) Humidity and Temperature Sensor (DHT11), which traces the temperature change. All these sensors are connected to the Node MCU ESP8266 microcontroller, which is also a Wi-Fi module. It uploads the data to the cloud and displays it in the form of readings detected by the Blynk Application. This sensor's reading values control the pump for emergency purposes, such as stopping the pump for irrigation. Thus, this project can automate the irrigation process by analyzing soil moisture and climatic conditions, covering essential aspects like less labor, power consumption, reliability, and cost.

Abstract

Purpose

The study aims to define the term “generation” by proposing an integrated design based on age-period-cohort effects and by proposing an Indian generational cohort framework categorizing Indian generational cohorts into four categories, namely, Baby Boomers, GenX, GenY, and GenZ. The study further aimed to capture the existing generational differences between GenY and GenZ cohorts in the Indian teams on team climate, transactive memory system, and team leader humility.

Design/methodology/approach

For the first two objectives a literature review methodology along with the author's proposition was adopted. An integrated design was proposed by reviewing the relevant sociological literature to define generations. Thereafter, an Indian cohort framework was proposed categorizing them into four groups Baby Boomers, GenX, GenY, and GenZ. Following that, for the last objective, i.e. to identify the differences between cohorts, empirical data were collected by a structured questionnaire that was disseminated to GenY and GenZ Indian working professionals. A total of 229 responses were used for observing the differences or similarities between GenY and GenZ cohorts on the study variables by employing an independent samples t-test.

Findings

The study proposed an integrated design (age, period, and cohort effect). Following that, an Indian generational cohort's framework has been outlined categorizing Indian cohorts based on their birth years, age groups, developmental stages, formative years, major Indian historical events, and various characteristics possessed by them. Moreover, the empirical findings support the existing generational disparities and depict that GenZ holds a higher inclination towards transactive memory systems and team climate whereas GenY holds more inclination toward leader humility.

Practical implications

The study put forth its contribution to research scholars by categorizing Indian generational cohorts in a rationalized manner based on an integrated design (age-period-cohort) effect. The study would further assist concerned authorities and managers in formulating HR policies to deal with the underlying generational differences highlighted by the study.

Originality/value

As there lies a paucity of generational frameworks in the Indian context, this study is the first attempt in this direction which categorizes Indian generational cohorts based on a unique integrated design including age-period-cohort effects. In addition, the study also investigated these cohorts in Indian organizations to observe the existing variations.

Abstract

Introduction: In the context of Sri Lanka, this study compares how institutions and financial development (FD) affect economic growth (EG) and inclusive growth (IG).

Purpose: The well-structured administration and judicial system at the provincial level have been established against the socioeconomic vulnerabilities in the country for an extended period. Still, the country as a whole and provincial level is experiencing huge income and social inequality, though there are required provisions for enhancing the well-being of the people.

Methodology: The study consists of data from the nine provinces from 2013 to 2019. The analysis used the Dynamic Spatial Durbin Model (D-SDM) to explore the spatial dependencies between the provinces. Two models were developed: the interaction of the financial service activities (FSA) and insurance, reinsurance, and pension (INPEN), representing the FD with the EG and IG with and without. The IG index was estimated by principal component analysis (PCA) using indicators of the four dimensions. The results indicated spatial dependency among FD’s interaction with EG when provincial tax (PROTAX) and provincial expenses (PROEXP) are the provincial institutions.

Findings: The IG model results showed the IG’s spatial dependency moderated by the FD and only the IG model between the provinces. PROEXP showed a significant positive spillover impact among provinces towards the IG.

Practical Implications: The finding inform economic policy making while identifying weaknesses in existing local governments. Attention must be given to how poverty can be reduced, enhancing the well-being of the people with the proper channelling of finance and government institutional mechanisms.

Abstract

Purpose

The purpose of this paper is to examine the degree of persistence of firm performance for publicly listed firms in Indonesia. The study also explores the impact of marketing expenditure on firm’s performance.

Design/methodology/approach

The data comprise 165 listed firms operating in Indonesia over the period 2007–2016. Dynamic panel regression estimations using Arellano and Bond (1991) and Blundell and Bond (1998) techniques have been deployed to generate the results.

Findings

The findings show the existence of positive persistence and sub-optimal level of competition in the performance of Indonesian firms. The results highlight that marketing intensity has a positive and significant impact on firm performance. The positive persistence hints at creation of substantial entry and exit barriers by the Indonesian firms and also indicate that Indonesian firms are able to create behavioral inertia among their consumers by properly directing their marketing efforts.

Practical implications

There is a need on the part of management to strengthen the short-term profit capabilities to nurture long-term benefits of profit maximization. On the regulators part, the authorities should frame the policies to foster long-run competition.

Originality/value

The current study contributes to the sparse literature on persistence of firm performance in the context of emerging economies like Indonesia. This is the first study on persistence of firm performance for publicly listed firms in Indonesia.

Abstract

Purpose

This study aims to examine the mediating role of product judgement in the relationship between electronic word-of-mouth (eWOM) and purchase intention. Additionally, it explores the moderating effects of source credibility and consumer ethnocentrism on the relationship between eWOM and product judgement, with a specific focus on Halal products. We utilise the Elaboration Likelihood Model (ELM) to investigate how individuals navigate the processing of information, distinguishing between central and peripheral routes. This exploration aims to enhance our understanding of how the ELM framework influences product judgement and purchase intention in the context of eWOM, with a focus on Halal products.

Design/methodology/approach

To achieve these objectives, an online survey was conducted in the United Kingdom. The study employed a moderated-mediation model, analysed using PLS-SEM.

Findings

The findings highlight the significant role of source credibility in the central route of information processing and purchase judgements. This study confirms that Halal product judgement fully mediates the relationship between eWOM and purchase intention. Additionally, it reveals that higher source credibility amplifies the impact of eWOM on consumer judgement. However, no significant moderating effect of consumer ethnocentrism on the relationship between eWOM and product judgement was observed in this context.

Originality/value

This study enhances our understanding of how Halal products are adopted in non-Muslim societies, shedding light on persuasive processes. Additionally, it refines the ELM in the context of cross-cultural consumer behaviour. The findings underscore the importance of prioritising source credibility in communication to shape information evaluation and persuasion.
