The purpose of this study is determination of cadmium using silver-gold bimetallic nanoparticles (Ag-Au BMNPs) and an aptamer modified glassy carbon electrode.

The maximum response of modified electrode was obtained with, 50 mV pulse amplitude, 20 mV/s scan rate in phosphate buffer of pH 4.0. Ag-Au BMNPs, as the mediators improved electron transmit during the entire electron transfer process and the aptasensor response. Herein, the authors used aptamer as the capture probe to prepare an aptasensor with enhanced stability.

The proposed aptasensor exhibited a wide linearity to cadmium in the range of 0.001–0.100 µg/L with a low detection limit of 0.005×10⁻³ µg/L. The glassy carbon electrodes with Ag-Au BMNPs showed a lower detection limit.

This aptasensor has good reproducibility, stability and repeatability and is cost-effective to regenerate. The specificity and selectivity of the novel modified electrode is tested in the presence of other interfering metal ions such as Fe²⁺, Mn²⁺, Mg²⁺, Sb³⁺ and Bi³⁺. The aptasensor shows 10 times more sensitivity and selectivity for Cd²⁺ ions.

This paper aims to investigate the causal inferences between mobile application adoption and changes in travelers’ purchasing behavior regarding services supported by the travel and tourism industry.

Using a quasi-experiment conducted by an airline, data sets from more than 10,000 travelers were collected, and hypotheses were tested using propensity score matching and difference-in-difference methods.

Mobile application adoption has a significant positive effect on the total purchasing frequency of services and a significant adverse effect on booking tickets in advance and purchasing frequency from self-owned websites. Besides, this finding also suggested that members or travelers who had high average purchases in the past tend to buy more air tickets on average after mobile application adoption, while the number of days to book tickets in advance and purchase auxiliary services declined after mobile application adoption. However, males purchased more auxiliary services via mobile applications.

The study is based on the causal effect of mobile application adoption on purchasing behavior. Nevertheless, the theoretical basis remains relatively weak. Furthermore, the underlying mechanisms that cause the changes in purchasing behavior via mobile applications need to be elucidated.

This study enriches the hospitality and tourism literature on mobile application adoptions, multichannel purchasing behavior and revenue management. First, a quasi-experimental design is used to verify a causal relationship between mobile applications’ adoption and travelers’ purchasing behavior in the travel and tourism industry. Second, this study adds to examining travelers’ multichannel purchasing behavior in the travel and tourism industry. Third, this work enriches the current literature that explores auxiliary services and revenue management in the travel industry.

Mobile application adoption significantly impacted the travel and tourism industry. Besides, To the best of the authors’ knowledge, this is one of the first empirical studies that examined changes in purchasing behavior due to mobile application adoption from the perspective of service type. The findings provide the first evidence of the impact of mobile application adoption on service purchasing in the travel industry.

The study aims to understand how corporate social responsibility (CSR) and happiness are used together in various research studies to serve the ultimate goal of corporate sustainability (CS), which in turn contributes to sustainable development.

A systematic literature review (SLR) was made using Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) method in the two most-reputable databases of Web of Science (WoS) and Scopus, revealing a final list of 54 studies to analyse.

The review concludes that the literature on CSR and happiness provides three main findings: first, concerning the pillars of sustainability, most of the studies concentrate on people, neglecting the planet and profit, second, employees are subject to the highest number of studies as the target of CSR initiative and third, almost all studies employed the hedonic aspect of happiness in CSR literature.

This particular research finding points to the need for developing a comprehensive framework to assess stakeholder happiness from both hedonic and eudaimonic aspects from a CSR perspective which is then represented under the three pillars of sustainability.

To contribute to the ultimate goal of CS, management would design CSR initiatives for all stakeholders to increase both hedonic and eudaimonic happiness of them.

The literature provides reviews of research in CSR and happiness separately; however, there is not any research revealing how these two concepts are used together in studies and how this association could be read to serve the goal of CS.

The purpose of this paper is to investigate the factors affecting citizens’ intentions toward sustainable tourism based on a research model integrating two theories: protection motivation theory (PMT) and theory of interpersonal behavior (TIB).

After in-depth interviews with ten people, the authors determined the official research model and builds a complete survey. With the random sampling method, data were collected from 628 Vietnamese respondents at some schools, enterprises and supermarkets. Using the PLS-SEM method, measurement and structural models were evaluated before testing the research hypotheses about the influence of factors on intention toward sustainable tourism.

This paper shows that all constructs of the integrated model PMT-TIB are related to intention toward sustainable tourism, and response efficacy is the most influential factor among the factors included in the research model. PMT-TIB integration model is proven to be superior to the original PMT and TIB models when studying factors affecting intention toward sustainable tourism.

The main limitation of this paper is that the PMT-TIB integration model only mentions motivational and interpersonal factors that influence intention toward sustainable tourism.

The findings indicate that state management agencies and enterprises need to develop specific action programs about each harmful environmental pollution caused by unsustainable tourism, raising awareness about the possibility of environmental protection through sustainable tourism.

This study contributes to the existing theoretical framework by integrating PMT and TIB for the first time in explaining intention toward sustainable tourism. This paper gives implications for Vietnam in particular and developing countries in general in promoting sustainable tourism intentions toward sustainable development according to the government’s goals.

本文的目的是基于保护动机理论（PMT）和人际行为理论（TIB）理论相结合的研究模型, 调查影响公民可持续旅游意愿的因素。

在对10人进行深入访谈后, 作者确定了正式研究模型并建立了完整的调查。 采用随机抽样的方法, 从部分学校、企业和超市收集了628名越南受访者的数据。 在检验有关因素对可持续旅游意向影响的研究假设之前, 使用 PLS-SEM 方法对测量和结构模型进行了评估。

本文表明, 综合模型 PMT-TIB 的所有构造都与可持续旅游的意愿相关, 而响应效能是研究模型中包含的因素中影响最大的因素。 在研究影响可持续旅游意愿的因素时, PMT-TIB集成模型被证明优于原始PMT和TIB模型。

本文的主要局限性是 PMT-TIB 整合模型仅提到动机和人际因素影响可持续旅游的意愿。

研究结果表明, 国家管理机构和企业需要针对不可持续旅游业造成的各种有害环境污染制定具体的行动计划, 提高人们对通过可持续旅游业保护环境的可能性的认识。

本研究首次整合PMT和TIB来解释可持续旅游业的意图, 为现有的理论框架做出了贡献。 论文对越南和广大发展中国家在促进可持续旅游意愿、根据政府目标实现可持续发展方面给出了启示。

El objetivo de este artículo es investigar los factores que influyen en la intención de los ciudadanos hacia el turismo sostenible basándose en un modelo conceptual que integra la teoría de la motivación hacia la protección (PMT) y la teoría del comportamiento interpersonal (TIB).

Tras la realización de entrevistas en profundidad con 10 personas, los autores determinaron el modelo de investigación y elaboraron un cuestionario. Utilizando un muestreo aleatorio para la recogida de datos, se obtuvieron 628 encuestados vietnamitas en escuelas, empresas y supermercados. Se empleó el análisis PLS-SEM para evaluar los modelos de medición y modelos estructurales antes del contraste de las hipótesis de investigación sobre la influencia de los factores en la intención hacia el turismo sostenible.

Este artículo muestra que todos los constructos del modelo integrado PMT-TIB están relacionados con la intención hacia el turismo sostenible y la eficacia de la respuesta es el factor más influyente entre los factores incluidos en el modelo conceptual. Se comprueba que el modelo integrador PMT-TIB es superior a los modelos PMT y TIB originales al estudiar los factores que afectan la intención hacia el turismo sostenible.

La principal limitación de este artículo es que el modelo de integración PMT-TIB solo utiliza factores motivacionales e interpersonales que influyen en la intención hacia el turismo sostenible.

Las conclusiones indican que los organismos estatales de gestión y las empresas deben desarrollar programas de acción específicos sobre cada contaminación ambiental nociva causada por el turismo insostenible, concienciando sobre la posibilidad de proteger el medio ambiente a través del turismo sostenible.

Este estudio contribuye al marco teórico existente al integrar por primera vez la PMT y la TIB en la explicación de la intención hacia el turismo sostenible. El trabajo ofrece implicaciones para Vietnam en particular y para los países en desarrollo en general en la promoción de las intenciones de turismo sostenible, hacia un desarrollo sostenible de acuerdo con los objetivos gubernamentales.

Globally, the governance has shifted from positivist to the regulatory-centric approach, necessitating accurate contouring of regulatory governance framework. The study proposes a novel approach to unravel the regulatory governance framework in the context of the Indian electronics industry – extendable to other sectors in India and other emerging economies.

The research objective has been operationalized through document analysis and thematic analysis of semi-structured interview transcripts in three steps: (1) arrive at parameters of the regulatory governance framework, (2) identify instruments against each parameter and (3) characterize parameters in terms of dominant instruments and their underlying modalities. The authors have adopted a set of 6 Cs modalities (control, communications, competition, consensus, code and collaboration) and regulatory space theory to analyze existing modalities mix in the dominant instruments.

In summary, the study has (1) identified eight macro and twenty micro regulatory governance parameters, (2) mapped regulatory governance parameters with instruments and institutions (3) revealed the top two dominant modalities for each regulatory governance parameter.

The existing modality characteristics of regulatory governance parameters can be used by manufacturers, investors and other stakeholders to make a realistic assessment of regulatory governance and reduce regulatory risk and regulatory burden.

The multidimensional use of parameters, instruments and modalities broadens the understanding of the existing regulatory governance framework and may assist the regulators in optimizing it to meet market requirements.

The purpose of this paper is to examine the purchase behavior of consumers towards green products by adapting and extending the theory of planned behavior with the inclusion of three pertinent environmental factors posited to reflect environmental consciousness in the form of environmental concern, environmental knowledge and environmental values.

The data was collected from 410 consumers at shopping malls with retail stores selling green and non-green products in a developing country using cluster sampling and analyzed using covariance-based structural equation modeling.

The findings of this study indicate that environmental factors reflecting environmental consciousness positively influence consumers’ attitude towards purchasing green products, wherein consumers’ environmental values have a stronger influence than their environmental concern and environmental knowledge. The findings also reveal that subjective norm, attitude and perceived behavioral control toward purchasing green products positively shape green purchase intention. The same positive effect is also witnessed between green purchase intention and behavior. However, perceived behavioral control towards purchasing green products had no significant influence on green purchase behavior.

This study suggests that green marketers should promote environmental consciousness among consumers to influence and shape their planned behavior towards green purchases. This could be done by prioritizing efforts and investments in inculcating environmental values, followed by enhancing environmental knowledge and finally inducing environmental concern among consumers. Green marketers can also leverage subjective norm and perceptions of behavioral control toward purchasing green products to reinforce green purchase intention, which, in turn, strengthens green purchase behavior. This green marketing strategy should also be useful to address the intention–behavior gap as seen through the null effect of perceived behavioral control on purchase behavior toward green products when this strategy is present.

This study contributes to theoretical generalizability by reaffirming the continued relevance of the theory of planned behavior in settings concerning the environment (e.g. green purchases), and theoretical extension by augmenting environmental concern, environmental knowledge and environmental values with the theory of planned behavior, resulting in an environmentally conscious theory of planned behavior. The latter is significant and noteworthy, as this study broadens the conceptualization and operationalization of environmental consciousness from a unidimensional to a multidimensional construct.

Intellectual capital (IC) is beneficial to the improved performance of businesses, irrespective of their industry. The present study proposes to check if the use of IC can also help in improving the asset quality of banks. Thus, this study aims to examine the impact of IC and its components on non-performing assets (NPAs).

The study has been conducted with a sample of 30 Indian commercial banks and analysed over a time frame of 15 years (2004–2005 to 2018–2019). The modified value-added intellectual coefficient model has been used to measure the independent variables, IC, and its components. The dependent variable, NPA, has been represented by the net NPA ratio. Two-step system generalized methods of moments (SGMMs) have been applied for the regression analysis. Along with the short-term estimates provided by the SGMM approach, the long-term impact of explanatory variables on the dependent variables has also been seen.

The results of the study show that IC and its components are indeed helpful for the management of NPA, as they impact the problem loans negatively. Furthermore, the long-term benefits of IC in enhancing bank credit quality are more substantial.

The results from the present study can be used by bank management. The bank managers can draw inferences that the efficient application of IC can help them reduce their loan losses. Developing skills and knowledge of employees, maintaining close relations with stakeholders, significantly the customers, and putting more sophisticated processes and infrastructure to use can help banks to control their loan losses.

A major proportion of studies examining the role of intangible assets in various aspects of the banking sector focuses on the association between IC and the financial performance of banking entities. However, for banking institutions, apart from financial performance, improving credit quality is also imperative for staying afloat. Thus, to the best of the authors’ knowledge, the present study is one of the first to examine the relationship between knowledge-based assets (i.e. IC) and bank credit quality.

This paper aims to study whether the adoption of an entry mode that fits the social trust level contributes to the improvement of foreign subsidiary performance.

The authors used the Probit model, linear regression, strategic fit approach and instrumental variable regression. The sample was made up of 11,095 observations of Chinese multinational enterprises' foreign subsidiaries in 54 countries from 2005 to 2020.

The results suggest that a host country with a high level of social trust results in fewer difficulties for enterprises in gaining legitimacy, thus foreign subsidiaries are more likely to select the wholly owned entry mode. The results also show that the effect is contingent on the formal institutions of host countries. The results of the mechanism test suggest that social trust influences subsidiaries' entry mode choice by reducing information asymmetry, costs and uncertainty risks. This study further finds that selecting a fit entry mode based on social trust level substantially increases foreign subsidiary performance and this effect is more significant when multinational enterprises (MNEs) are state-owned enterprises (SOEs).

The main limitation of this paper is its only focus on foreign subsidiaries of Chinese MNEs, which may limit the generalizability of research findings.

This paper responds to the call for conducting more research on informal institutions. Findings highlight the critical role of informal institutions in helping foreign subsidiaries in gaining legitimacy in host countries and the essentialness of selecting a fit entry mode based on the informal institutions of host countries for the development of foreign subsidiaries.

The current era of the fourth industrial revolution has attracted significant research on the use of digital technologies in improving construction project delivery. However, less emphasis has been placed on how these digital tools will influence the management of the construction workforce. To this end, using a review of existing works, this chapter explores the fourth industrial revolution and its associated technologies that can positively impact the management of the construction workforce when implemented. Also, the possible challenges that might truncate the successful deployment of digital technologies for effective workforce management were explored. The chapter submitted that implementing workforce management-specific digital platforms and other digital technologies designed for project delivery can aid effective workforce management within construction organisations. Technologies such as cloud computing, the Internet of Things, big data analytics, robotics and automation, and artificial intelligence, among others, offer significant benefits to the effective workforce management of construction organisations. However, several challenges, such as resistance to change due to fear of job loss, cost of investment in digital tools, organisational structure and culture, must be carefully considered as they might affect the successful use of digital tools and by extension, impact the success of workforce management in the organisations.
