Abstract

Purpose

Learning to rank algorithms inherently faces many challenges. The most important challenges could be listed as high-dimensionality of the training data, the dynamic nature of Web information resources and lack of click-through data. High dimensionality of the training data affects effectiveness and efficiency of learning algorithms. Besides, most of learning to rank benchmark datasets do not include click-through data as a very rich source of information about the search behavior of users while dealing with the ranked lists of search results. To deal with these limitations, this paper aims to introduce a novel learning to rank algorithm by using a set of complex click-through features in a reinforcement learning (RL) model. These features are calculated from the existing click-through information in the data set or even from data sets without any explicit click-through information.

Design/methodology/approach

The proposed ranking algorithm (QRC-Rank) applies RL techniques on a set of calculated click-through features. QRC-Rank is as a two-steps process. In the first step, Transformation phase, a compact benchmark data set is created which contains a set of click-through features. These feature are calculated from the original click-through information available in the data set and constitute a compact representation of click-through information. To find most effective click-through feature, a number of scenarios are investigated. The second phase is Model-Generation, in which a RL model is built to rank the documents. This model is created by applying temporal difference learning methods such as Q-Learning and SARSA.

Findings

The proposed learning to rank method, QRC-rank, is evaluated on WCL2R and LETOR4.0 data sets. Experimental results demonstrate that QRC-Rank outperforms the state-of-the-art learning to rank methods such as SVMRank, RankBoost, ListNet and AdaRank based on the precision and normalized discount cumulative gain evaluation criteria. The use of the click-through features calculated from the training data set is a major contributor to the performance of the system.

Originality/value

In this paper, we have demonstrated the viability of the proposed features that provide a compact representation for the click through data in a learning to rank application. These compact click-through features are calculated from the original features of the learning to rank benchmark data set. In addition, a Markov Decision Process model is proposed for the learning to rank problem using RL, including the sets of states, actions, rewarding strategy and the transition function.

Abstract

Purpose

The purpose of this paper is to examine how a country’s change readiness impacts international mergers and acquisitions (M&A) capital flows on a national level toward host countries. The authors unpack the construct of change readiness and identify how its different dimensions impact international M&As (IMA). The authors provide a theoretical framework based on the resource-based view to facilitate an understanding of this concept.

Design/methodology/approach

The authors used a fixed-effect analysis to study a sample of 2,970 IMAs announced by publicly traded US companies during 2013–2017.

Findings

The authors propose that higher levels of change readiness would help foreign firms to cope with risks and uncertainties generated by the changes and shocks in the environment of a host country. The authors find support for their hypotheses showing that higher levels of change readiness increase the number of IMAs that a country receives every year. This characteristic of the host country shows a significant influence, especially in technology-intensive IMA flows.

Practical implications

This study provides implications for business executives and policymakers both in terms of risk mitigation strategies and investment attraction. Understanding the fact that when it comes to foreign investment in the form of IMAs business executives are aware of the importance of change readiness in host countries might lead to motivate the governments and host country officials to provide better infrastructure to boost the change readiness in their economy.

Originality/value

Overall, this study improves our knowledge about mechanisms through which change readiness of host countries might impact firms' strategies for international expansion. As we are indeed living in the era of global disruptions and strong shocks caused by political turmoil, climate change and the spread of new diseases, this study contributes to the literature on risk mitigation in international business and is one of the first to look closely at the role of host countries' change readiness and the effect it might have on attracting international M&As.

Abstract

Purpose

This study aims to evaluate the association between dietary patterns with health status and smoking-related knowledge, attitudes and practices (s-KAP) among Bangladeshi adolescent smokers.

Design/methodology/approach

An analytical cross-sectional study was conducted among 205 randomly selected adolescents. Socio-demographic, health status, s-KAP related data were collected in face-to-face interviews. Dietary intake data were calculated using the food frequency questionnaire.

Findings

The practices score (44.8%) was comparatively poor among adolescent smokers. Among the respondents, around 56.1%, 38.1% and 49.3% were suffering from gastric problems, nausea and the loss of appetite, respectively, because of smoking. There was a significant relationship between dietary diversity and the occurrence of several diseases such as gastric problems, nausea and loss of appetite. The respondents who consumed fresh fruits and vegetables regularly might reduce gastric problems (OR: 0.53, 95% CI: 0.27–1.04 and OR: 0.64, 95% CI: 0.25–1.65), nausea (OR: 0.72, 95% CI: 0.38–1.37 and OR: 0.28, 95% CI: 0.13–0.84) and loss of appetite (OR: 0.52, 95% CI: 0.32–1.21 and OR: 0.16 95% CI: 0.27–0.68).

Originality/value

In conclusion, smoking has been associated with multiple health problems because of poor practices score. Consumption of a balanced diet, better smoking-related knowledge, attitudes and practices needs to be improved among adolescents.

Abstract

Purpose

This study aims to examine the collective impact of awareness and knowledge about fake news, attitudes toward news verification, perceived behavioral control, subjective norms, fear of missing out (FoMO) and sadism on social media users’ intention to verify news before sharing on social media.

Design/methodology/approach

The current study’s conceptual framework is developed by a comprehensive literature review on social networking and the theory of planned behavior. The data for samples were collected from 400 respondents in India to test the conceptual framework using the partial least square–structural equation modeling technique.

Findings

The results show that awareness and knowledge, perceived behavioral control, attitudes toward news verification and FoMO are significant predictors of intention to verify news before sharing.

Research limitations/implications

The present study concludes implications for managers of social media companies and policy actors that want to take steps toward arresting the spread of fake news via social media.

Originality/value

Academic investigation on fake news sharing on social media has recently gained traction. The current work is unique because it uses the theory of planned behavior as a basis for predicting social media user’s intention to verify news before sharing on social media.

Abstract

Purpose

Many studies have not fully explored the relationship between knowledge and information system strategies (ISS) and their overall impact on firm performance (FP). In an attempt to address this knowledge gap, this study draws on the dynamic capabilities view, and on recent literature on knowledge strategy planning (KSP), and examines the alignment between KSP and ISS to enable dynamic capabilities innovation capabilities (DCIC) to gain FP.

Design/methodology/approach

The survey examined empirical data from 234 Brazilian companies using the partial least squares path modeling to test the hypotheses proposed herein.

Findings

The empirical results confirmed that both KSP and ISS have a positive impact on DCIC. Furthermore, the results indicated that FP was positively impacted through DCIC. The results indicated that the alignment between KSP and ISS positively impacts DCIC and ultimately FP.

Research limitations/implications

The data was collected from 234 Brazilian companies in a country classified as a developing economy. Future studies could investigate the impact of KSP and ISS on FP in developed economies. The practical implication of the study required managers to be knowledgeable about the value of alignment between KSP and IT capabilities involving more practitioners in the strategy-as-practice to create innovation capabilities and enhance FP.

Originality/value

This is one of the earliest studies that has investigated the relationships between KSP and ISS and their impact on FP within a developed economy context. The relationship between all constructs that have not been addressed previously contributes to extend the literature on KSP, ISS and dynamic capabilities view.

This study investigates the effect of protection motivation theory (PMT) constructs on Arab women's feelings while seeking information during the COVID-19 pandemic.

Abstract

Purpose

This study investigates the effect of protection motivation theory (PMT) constructs on Arab women's feelings while seeking information during the COVID-19 pandemic.

Design/methodology/approach

The study has adopted a mixed-method approach using semi-structured interviews and a questionnaire to explore PMT constructs' impact on women's feelings while seeking information on COVID-19. Several tests, such as standard deviation, mean, skewness, kurtosis and persons, were used to check the reliability of data and inter-relationships between constructs.

Findings

The study results show a significant positive correlation between PMT constructs (perceived vulnerability, perceived severity, response efficacy, self-efficacy and response cost) with the feelings of Arab women during information seeking on COVID-19. However, the relationship between threat appraisal and feelings during information seeking was more substantial than coping appraisal and feelings during information seeking. The researchers hope that this study creates a baseline of cross-cultural studies on PMT constructs' effect on women's feelings while seeking health information.

Research limitations/implications

The current study was conducted on female participants only. While the study intended to examine Arab women's feelings during information seeking with PMT's application, the results may be affected by other factors that were not considered in the current study. Furthermore, the questionnaire was distributed in three Arab countries, which means that the results cannot be generalized in other geographical contexts. Therefore, similar studies need to be conducted in larger geographical areas as cultural factors may produce different results.

Originality/value

This study explores women's feelings while seeking COVID-19 information using the PMT constructs. As far as we know, this study is the first study to investigate Arab women's feelings while seeking health information during pandemics. PMT utilization is considered a new approach to discover and measure informational needs and feelings associated with it during pandemics.

Abstract

Purpose

Today social media capabilities have enabled businesses and enterprises to more collaboration, engagement and co-creation with their customers. So the current paper expands on this notion. The aim of this study is a bibliometric analysis to examine the trends of publications in the field of co-creation based on social media.

Design/methodology/approach

To data collection of quantitative analysis, Scopus database was selected and the collected data were analyzed using Bibliometrix-package. The Web of Science also was selected to retrieve highly cited and hot papers for qualitative part of analysis besides top 10 Scopus highest citation per year documents on June 6, 2020.

Findings

The results indicate insights into research trends pertaining to social media-based co-creation, as follows: starting jump to the publications occurred in this researches from the year 2008 and the growth trend is progressing in recent years; the stressful points are “co-design,” “co-creation” and “value co-creation” and concepts such as “open innovation,” “co-innovation” and “co-new product design” are new topics that guide future direction; the USA and UK are leaders in number of multiple and single publications; the most active and top journals that are better suited to achieving a high citation rate per year for a related paper were introduced. In addition, the top documents and highly cited papers were qualitatively analyzed on the basis of times cited per year.

Research limitations/implications

The current study is not free of limitations. The database was limited to only Scopus. So the patterns and trends generated in the study may not be generalized to all social media-based co-creation research. Of course, the authors did not intend to ignore other contributions. It is mainly because of the number of documents retrieved from Scopus database and the coverage, Scopus was selected. Moreover, other types of research techniques such as correspondence analysis can be incorporated to generate additional meaningful insight.

Originality/value

In this time of social media and user-generated content portals, co-creation through social media has become quite popular. So the main innovation of this study is providing a visual presentation of the trends and patterns in the evaluation of social media-based co-creation from the first document about the research area published till 2020. The results of this paper can shed light on the factors that strengthen the contribution of studies in a research area. Generally, the bibliometric items the authors analyzed essentially show the entire field picture and guide researchers toward understanding future trends to produce impactful studies.

Abstract

Purpose

This study aims to investigate the mechanism between perceived organizational support and transfer of training using self-efficacy and job satisfaction as mediating variables. More specifically, self-efficacy is examined as a mediator between perceived organizational support and job satisfaction, whereas job satisfaction is examined as a mediator between perceived organizational support and transfer of training.

Design/methodology/approach

This quantitative study is based on data collected from 409 employees of the banking sector on a random basis.

Findings

Structural equation modeling analysis confirmed the mediating role of job satisfaction between perceived organizational support and transfer of training. In addition, self-efficacy was found to perform the mediating role between perceived organizational support and job satisfaction.

Research limitations/implications

The data for this study were collected at one point of time, and it has implications for organizations and employees.

Originality/value

This study highlights the emerging issue of transfer of training and gives a practical model to the organizations to strengthen their human resources. This study is perhaps the first attempt to empirically investigate the mediating role of self-efficacy and job satisfaction.

Abstract

Purpose

The purpose of this study is to examine people’s preferences for some of the key attributes of emergency shelters, including type, privacy level, location, spatial arrangement and pet-friendliness.

Design/methodology/approach

Choice experiment (CE) method was used in this study. A standard CE questionnaire was designed and completed by a sample of 293 residents of the Greater Toronto Area, Ontario (Canada), during the winter of 2015.

Findings

When using publicly provided shelters, people prefer to stay in hotels, places of worship and then community shelters, in that order. These findings correspond to the values that they place for various attributes through the CE survey. Findings show that responders place the highest values for emergency shelters that provide more privacy, located close to their home, and are pet friendly. Type of shelter and the “arrangement” attributes were not found to be as important and valuable.

Research limitations/implications

This study uses a convenient sampling method as such may not fully represent the study population.

Practical implications

Emergency shelter provision by local, regional and national governments cost significant amount of money and thus it is important that the society get the maximum benefit from it. This will be possible when users’ preferences are considered in planning, design, and operation of emergency shelters. The findings enable emergency managers to perform cost-benefit analysis an increase the efficiency of emergency shelters.

Originality/value

While previous studies have examined emergency-shelter types, characteristics and user-satisfaction levels, this is a novel study because it uses a choice experiment method to extract monetary values for key emergency-shelter attributes.
