The purpose of this paper is to develop a practical implementation blueprint for the attainment of food security for all Nigerians based on sustainable agricultural practices.

This paper conducted a critical review of 66 peer-reviewed empirical articles on various sustainable agricultural case studies. The evidence obtained from this review and the in-depth knowledge of the authors regarding the Nigerian agricultural landscape was used to develop a practical implementation blueprint for achieving food security in the country.

The food security for all Nigerians (FOSFAN) blueprint was developed and comprising of eight practical and interconnected steps. These steps take into consideration the synergistic effort of the government, the ministry of agriculture and its corresponding agencies in ensuring that farmers attain sustainable practices in their endeavour.

The findings of this paper will contribute to existing literature on food security and will also serve as a baseline for deeper empirical exploration of the impact of sustainable agricultural practices on food security in Nigeria (a country in the Sub-Saharan region).

The FOSFAN blueprint provides a practical and comprehensive step-by-step guide, which the Nigerian Ministry of Agriculture can use to achieve food security for all Nigerians.

This paper is addressed towards the development of food security plan in the Nigerian context in which the Nigerian Government ensures the availability of food to all its citizens in a bid to achieve “Zero Hunger”, which is the second Sustainable Development Goal.

The FOSFAN blueprint is a proactive guide that takes into consideration the importance of cultural and socioeconomic nuances in the development of a sustainable agriculture policy in a developing country context.

There have been many challenges in crawling deep web by search engines due to their proprietary nature or dynamic content. Distributed Information Retrieval (DIR) tries to solve these problems by providing a unified searchable interface to these databases. Since a DIR must search across many databases, selecting a specific database to search against the user query is challenging. The challenge can be solved if the past queries of the users are considered in selecting collections to search in combination with word embedding techniques. Combining these would aid the best performing collection selection method to speed up retrieval performance of DIR solutions.

The authors propose a collection selection model based on word embedding using Word2Vec approach that learns the similarity between the current and past queries. They used the cosine and transformed cosine similarity models in computing the similarities among queries. The experiment is conducted using three standard TREC testbeds created for federated search.

The results show significant improvements over the baseline models.

Although the lexical matching models for collection selection using similarity based on past queries exist, to the best our knowledge, the proposed work is the first of its kind that uses word embedding for collection selection by learning from past queries.

Employee’s service innovative behavior lays the groundwork for bottom-up innovation and ongoing service improvement in service firms. Therefore, it is vital for service organizations to understand the antecedents of employees service innovative behavior. Drawing upon the social cognitive theory, this study aims to develop a research model that examines the effects of ethical and entrepreneurial leadership on service innovative behavior.

Data were collected from 178 managers and 415 employees working in 178 small- and medium-sized (SME) hotels in Vietnam.

The findings showed that ethical leadership has direct and indirect effects on service innovative behavior, while entrepreneurial leadership only influences service innovative behavior via intrinsic motivation. In addition, trust in leader moderates the effect of intrinsic motivation on service innovative behavior

The study advances current scholarly research on leadership by combining the two areas of entrepreneurial and ethical leadership into one theoretical model and examines how these leadership styles generate hospitality employees’ service innovative behavior through the mediating effect of intrinsic motivation and the moderating effect of trust in leader.

The findings of this research offer significant implications for SME hotels and their managers. In their recruitment processes, hotels should search for particular personality traits, which have been found to predict ethical and entrepreneurial leadership. Hospitality firms also need to encourage communication between leaders and co-workers to enhance employees’ intrinsic motivation.

There are calls for research to examine whether both entrepreneurial and ethical leadership styles can be integrated to enhance employees’ positive outcomes. Evidence about the mechanism linking entrepreneurial and ethical leadership to service innovative behavior is limited. With this stated, the current study makes significant contribution to leadership and innovation literature by filling in these voids.

Recent socio-economic trends have made Artificial intelligence (AI) a vital institutional force driving development among countries with optimal opportunities and costs. Among researchers in this domain, the benefit of AI is highly espoused, having been underexplored in Africa. However, the outbreak of the COVID-19 pandemic has highlighted the need to strengthen the education sector, given that many schools have migrated their teaching and learning online. While face-to-face teaching was the norm, the transition to online teaching has brought about the need to rethink the use of Information Technology to strengthen teaching and learning. To proffer solutions for the implementation of AI in Africa, there is the need to understand the challenges. Therefore, in this chapter, we explore the possible challenges that hinder the implementation of AI in Africa. Further, we propose solutions for the implementation of AI in the education sector, especially in this era of the COVID-19 pandemic. The solutions stem from rethinking the role of AI in the education sector. Finally, a conceptual framework that synthesises the problems and the proposed solution is developed. We envision that the proffered solutions can mitigate the deepening misconceptions and challenges bedevilling AI implementation in Africa.

The purpose of this paper is to explore the effect of affiliative-based humorous leadership on hotel employee outcomes (i.e. resistance to change and upward voice), underpinned by affective events theory. Further, this paper investigates psychological capital as a mediation effect and emotional intelligence as a moderation effect.

Using a structured questionnaire, 554 supervisors of 20 four- and five-star hotels in Sharm El-Sheikh responded based on a time-lagged approach. A Smart-partial least squares (Smart-PLS) v. 3.3.9 was used to analyze the data set.

The findings revealed that affiliative-based humorous leadership has a positive effect on psychological capital, and psychological capital has a positive association with employee upward voice. Psychological capital partially mediated the linkage of humorous leadership with employees' upward voices and resistance to change. According to the results, emotional intelligence strengthened the linkage of psychological capital with employee resistance to change and upward voice.

The findings contribute to the body of knowledge on humor and the development of new ideas in the hospitality literature. This paper adds to the hospitality literature on humorous leadership in developing countries, specifically in Egypt. This paper also provides practitioners with new perspectives as they develop strategies and use humor-related wise leadership styles in the workplace.

To the best of the authors’ knowledge, this paper is one of the first studies to assess affiliative-based humor in leadership in the hospitality industry. This paper contributes to future studies on the crucial effect of workplace engagement and its association with employees’ novel and intriguing actions and offers a good guideline for organizations and enterprises wishing to better leverage leader humor.

The smart sustainable cities (SSC) concept has a wide acknowledgement amongst governments and societies that deal with emerging technology and help in developing better urban communities. However, the fact that citizens' participation (CP) is not adherent to the current policies and governance often boosts their aspirations of decision-making to become smart cities. This paper aims to identify SSC variables and, more importantly, rank, categorise and discuss the factors towards implementing SSC by engaging, empowering and enabling citizens to participate in the urban development of SSC.

A comprehensive literature review identified 38 factors in the CP process. Those factors were used to design an online questionnaire administered to the respondents. A total of 164 valid responses were collected. A two-stage statistical analysis was adopted. First, the Relative Importance Index (RII) was used to rank and prioritise the importance of the factors that affect the current policies and agenda. Second, factor analysis was utilised to categorise and group those factors.

This study founds four significant factors that help in implanting SSC: “knowledge of smart sustainable cities”, “awareness of smart sustainable cities”, “willingness of the citizens to participate” and “opinion on the current agenda of the government's role”.

This study has a few limitations which can be considered in future studies. First, the response rate of the participant is relatively low (163), so sampling a larger segment will support the broader perception of the citizens.

The outcome of this paper underlines the need for the successful implementation of smart cities by adopting CP in the process of impacting policies and governance. Particularly, it identifies factors that help cities and policymakers in engaging CP in developing new policies and revising existing policies for promoting SSC.

There is a need to investigate the most critical factors that influence CP for implementing SSC. These factors have not been adequately examined in extant literature.

This study aims to find out the current state of cloud-based library services in selected academic and special libraries of Bangladesh. The study also explored some pertinent problems faced by librarians in implementing this new technology in library services and activities.

The study used a mixed-method approach with a range of exploratory research questions. Purposive sampling technique was used to select the libraries. A set of structured questionnaires was designed to address the objectives of the study. For in-depth analysis, short interviews with the library professionals were also conducted.

Only four libraries made use of cloud computing services, and they maintained a partial cloud environment. Most responding librarians treated cloud computing as a dynamically scalable infrastructure for applications, data and file storage with charges imposed. Most of the respondents (90%) preferred cloud computing for “Software-as-a-Service”. Due to the high subscription rate (70%), unreliable online payment system (60%) and trading system (60%), librarians treated cloud computing as a burden in providing library services and activities. Respondent librarians were also interviewed for exploring their views on cloud computing in library services. For adopting cloud computing in library services of Bangladesh, “sufficient financial allocation” and “organizations’ positive decision over cloud computing” were mentioned as challenging tasks by the respondents. Finally, the study suggested some solutions to the problem and proposed a model for a cloud-based library system that can be replicated in libraries and information centres of other developing countries too.

This paper encapsulates the overall scenario of cloud-based library activities and services in Bangladesh. Based on the available secondary sources, no empirical study on librarians’ perceptions of cloud computing in library services of Bangladesh has been carried out before this study. Thus, this is perhaps the first attempt to quantitatively measure cloud-based services in Bangladeshi libraries.

Building on leader-member exchange and social cognitive theories, this paper aims to propose a model of the influence of narcissistic leadership on hotel employees’ behavioral cynicism through the mediating roles of employee silence and negative work-related gossiping on this relationship.

The model was examined using covariance-based structural equation modeling using data collected from 468 employees working in several different departments in Italian hotels.

The findings illustrate that narcissistic leadership positively affects behavioral cynicism. Furthermore, employee silence and negative work-related gossiping are shown to have a significant mediating effect on this relationship.

The study may be of use for hotel managers as it demonstrates how narcissism can be very damaging to their organizations and employees.

To date, this study is the first to examine negative work-related gossiping and employee silence as mediator variables in the relationship between narcissistic leadership and behavioral cynicism in the hotel industry. Further, this research makes a significant contribution to the hospitality literature as the topic of narcissistic leadership has not, to date, been adequately investigated in the sector.

The purpose of this study is to investigate and articulate the performance appraisal process as a tool, used for the development of voice behavior through the fostering of trustworthiness and empowering culture in the organization.

Data has been collected through survey instruments, filled by employees and their coworkers. The study proposes and tests a new model based on the relationship between performance appraisal and voice behavior through the moderation-mediation mechanism. Data analysis has been performed using SEM through SMART PLS 3.

Results show that a strong and positive relationship exists between performance appraisal and voice behavior through the mediating variable of psychological empowerment. The moderators, empowering leadership and perceived fairness have played vital role in boosting psychological empowerment and strengthening the relationship with performance appraisal.

The study presents the performance appraisal system as one of the antecedents of employees' voice behavior generated through psychological empowerment (mediator) and perceived fairness and empowering leadership (moderators) since the appraisal system is to be implemented through the leader.

The study presents a unique and innovative idea while it tries to explore and measure the different effects/impacts of the relationship between performance appraisal and voice behavior.

The purpose of this paper is to investigate the double-edged effects of supervisor bottom-line mentality (BLM) on subordinates' work-related behaviors (work performance and knowledge hiding) and the moderating role of subordinate gender.

The theoretical model was tested using a sample of 218 three-wave multi-source data collected from employees of five firms in southern China.

The results revealed that supervisor BLM is positively associated with subordinate BLM. Although subordinate BLM can enhance their work performance, it can also lead to knowledge hiding toward coworkers. Furthermore, these indirect effects are moderated by subordinate gender.

Managers should pay more attention to the potential positive and negative consequences of supervisor BLM and intervene to mitigate the negative impact of BLM.

This study is among the first to examine how supervisor BLM can be a mixed blessing and elicit both positive and negative behaviors from their subordinates. Moreover, by illuminating how subordinate gender moderates the relationship between supervisor BLM and subordinates' work-related behaviors, we enrich and extend the BLM literature.
