Healthcare management efficiency has become a golden goal in the operations of modern healthcare organisations across zones and cultures. This study aims to investigate five dimensions of Ouchi’s theory Z approach, mutual organisational trust, long-term employment/job security, employee participatory decision-making, employee well-being and generalised career path, concerning healthcare efficiency in government tertiary hospitals during COVID-19 period.

The probability sampling strategy was adopted among 300 participants of the hospitals in the healthcare workforce of the study population. The study adopted multiple scales on the identified variables of theory Z and employed principal component analysis to evaluate the components of Ouchi’s Theory Z in relation to healthcare efficiency among the workforce of tertiary hospitals in Lagos State, Nigeria.

The outcome of this study shows that all the dimensions were significantly related to healthcare efficiency in the study hospitals. It depicts that mutual trust among employees has a positive influence on the efficiency of healthcare management in government tertiary hospitals, and long-term employment opportunity has a significant impact on the efficiency of healthcare management in government tertiary hospitals. Employee participatory decision-making is essential to the efficiency of healthcare management in government tertiary hospitals. Employee well-being is fundamental to the efficiency of healthcare management in government tertiary hospitals. Generalised career path of healthcare personnel has a tremendous impact on the efficiency of healthcare management in government tertiary hospitals.

This study is limited to healthcare employees in Lagos State, Nigeria. The implication is that as old as Ouchi’s theory, its relevance remains green in the heart of contemporary organisations today even in healthcare facilities in Nigeria which aids the management of the global pandemic, COVID-19 outbreak.

The study shows that Ouchi’s theory Z approach that combines the Japanese and American patterns of organisational management is highly relevant in the operations and management of government hospitals in Nigeria to date even in the era of COVID-19, the global pandemic season.

This study explored how the Singaporean government responded to the Covid-19 pandemic crisis from early January 2020 to the end of May of the same year. It evaluated the capability of Singapore's leadership management in a crisis during the peak and ravaging period of the Covid-19 pandemic.

The study utilised a systematic design analysis approach, analysing Singaporean cases on the Covid-19 crisis using a systematic and narrative approach to underscore the country's response to the pandemic attack from January 2020 to May 2020.

Against the backdrop of Singapore's peculiar political system of government dominated by the ruling People's Action Party (PAP) and culture of bureaucracy, the government has increasingly executed several control measures, including strict travel bans, contact tracing, the circuit breaker–lockdown, mask-wearing, social distancing orders as well as financial support to businesses and employees from top to the bottom in the country. However, the treatment and health issues of the migrant workers in the dormitories continue to be the major concern among academics and scholars. At the same time, policy inadequacies truncate the excellent measure of Singapore's response to Covid-19. The case point review concluded that the mortality rate in Singapore remains low compared to other nations of the world. Singapore's case points unveil fundamental learning that an excellent leadership-driven harmonised strategic model is essential for crisis management in any society. The finding of the analysis demonstrated that Singapore adopted a contingency and value-based leadership model to advance good governance and tackle the spread of the deadly coronavirus in its country.

The study has demonstrated a profound analysis that has not been conducted hitherto. Investigation of the Singapore case point is not a popular analysis among Nigerian scholars. Therefore, from Nigeria's perspective, the study has showcased the good and the wrong sides of a coin in Singapore's leadership and power dynamic in crisis management.

The mass exodus of the professional healthcare workforce has become a cankerworm for a developing nation like Nigeria, and this worsens the already depleted healthcare systems in underdeveloped nation. This study investigated the rationale behind medical workers' brain-drain syndrome and the quality healthcare delivery in the Nigerian public healthcare sector.

To stimulate an understanding of the effect of the phenomenon called brain drain, the study adopted a diagnostic research design to survey the public healthcare personnel in government hospitals. The study administered a battery of adapted research scales of different measures to confirm the variables of interest of this study on a probability sampling strategy. The study surveyed 450 public healthcare sector employees from four government hospitals to gather pertinent data. The study used a structural equation model (SEM) and artificial neural networks (ANNs) to analyse the collected data from the medical personnel of government hospitals.

The findings of this study are significant as postulated. The study discovered that poor quality worklife experienced by Nigerian medical personnel was attributed to the brain-drain effect and poor healthcare delivery. The study further demonstrated that job dissatisfaction suffered among the public healthcare workforce forced the workforce to migrate to the international labour market, and this same factor is a reason for poor healthcare delivery. Lastly, the study discovered that inadequate remuneration and pay discouraged Nigerian professionals and allied healthcare workers from being productive and ultimately pushed them to the global market.

Practically, this study has shown three major elements that caused the mass movement of Nigerian healthcare personnel to other countries of the world and that seems novel given the peculiarity of the Nigerian labour market. The study is original and novel as much study has not been put forward in the public healthcare sector in Nigeria concerning this phenomenon.

Personality profiling in today’s business world has become an essential organisational development practice targeted at identifying a set of employees' traits, which differentiate an employee from one another. Given the assumption that personality traits form an essential indicator of developing the potential of an individual workforce, possible to establish how employees function in a certain job role and their suitability for the particular tasks in an organisation. This study aims to explore the relationship between personality traits, assessment centres (ACs) quality and management development in Nigeria telecommunication organisation among its managers.

The study employed multi-stage sampling techniques and further stratified the hierarchy of the management and finally used a simple random sampling strategy on each stratum. A combination of 482 managers in Nigerian telecommunication organisations participated in this study. The study investigated 12 hypotheses and 1 mediating postulation. Multiple scales were adapted to measure dimensions of endogenous and exogenous variables along the path of mediating variables of the study. The study employed a cross-sectional survey approach to administering the research instrument across all the departments among the managers of the organisations. A structural equation model of assessment was used to analyse the data collected from managers of the telecoms organisations.

The outcome of the study was significant, 10 of the postulated hypotheses were found to be significant while 3 were not significant. The study revealed that a combination of openness to experience, conscientiousness, neuroticism, agreeableness and extraversion personality have no significant relationship with the AC. Also, employees who are high in neuroticism like being emotionally unstable did not find a significant relationship with the AC. In a similar situation, the combined effect of all the big-five personalities was not significant in management development among the managers of the telecommunication industry. The AC is discovered to mediate between personality traits and management development. Individually, the big-five model finds a significant relationship with AC and management development, respectively.

The study is restricted to managers of the Nigerian telecoms industry alone and not all the entire workforce. It adopted cross-sectional analysis to make an inference on all the managers of the organisations. The implication is that the period of the view of a particular point in a sequence of the event may not be representative. Another implication is that the results from the cross-sectional design are for the relationship, and they do not indicate causation.

In practice, this study has shown that personality profiling is important to managing organisational behaviour to highlight a set of traits of employees suitable for peculiar roles. This study implies that personality elements constitute a vital signal of the potential development of the workforce. It helps to illuminate an individual functioning style in a certain task situation, therefore determining both professional and managerial suitability in performing a given role.

Job satisfaction is indispensable in the daily life of the workforce, and the mechanism that drives job satisfaction requires the attention of the management of corporate organisations. The purpose of this paper is to investigate the predictors of work environment on job satisfaction among nurses in both federal and state tertiary hospitals in Lagos State.

The study used the longitudinal research design to elicit information from the respondents. The research instrument used is a nursing work index scale by Aiken and Patrician which has been established to have a high internal reliability coefficient. The simple random sampling strategy was used to administer the research instrument to 364 nurses. The study used hierarchical multiple regression to analyse the data obtained.

This study discovered that all the variables collectively determined nurses job satisfaction; however, the salary was the most fundamental essential predictor that drive nurses’ job satisfaction followed by advancement and promotion. All seven predictors, namely, socio-political climate; administrative and managerial support, autonomy and responsibility, salary, supervision and working condition, recognition and achievement, advancement and promotion, collectively exert positive relationship with nurses’ job satisfaction. The study concluded that to retain and prevent turnover intention among nurses, and other health-care workers, the management of hospitals must pay due attention to issues relating to job satisfaction, as this is likely to increase health-care system effectiveness, boost mental and social health of the nurses.

This study shows that job satisfaction in the workplace comes from diverse techniques, as other factors have been proven effective other than salary in international cultures and regions, but in Nigeria, salary and career promotion take pre-eminence above other factors. This is because of Nigerian socio-cultural realities and that is another paradigm shift.

Bureaucracy to a large extent entrenches orderliness and productive means of achieving goals in both public and private organisations across the world. However, bureaucracy is not suitable in the management of hospitals due to its peculiar nature of operations. This study investigates the conundrum of bureaucratic processes and health-care service delivery in government hospitals in Nigeria.

The study surveyed 600 outpatients and attendees visiting tertiary and government hospitals in Nigeria using descriptive design to obtained data from the respondents. A research instrument, questionnaire, was used to gather data. Out of the 600 outpatients visiting the 20 hospitals in government and tertiary hospitals, 494 responses were returned from the attendees. The study employed random sampling strategy to collect the information.

The findings of this study were that service delivery in government hospitals were in adverse position on all the four constructs of bureaucratic dimensions as against quality of service delivery in hospitals in Nigeria. It discovered that bureaucratic impersonality cannot impact on the quality of service delivery in government hospitals in Nigeria. Separation and division of labour among health workers have no significant effect on quality service delivery in government hospitals. Formal rules and regulations (administrative procedure, rules, and policies) prevent quality service delivery in government hospitals in Nigeria. Also, patient’s waiting time was not significant to the quality of service delivery in government hospitals.

The results are constrained with dimensions of bureaucratic processes. Thus, the implication of this study is that bureaucracy in the Nigerian public hospitals is an unnecessary marriage which should be carefully separated and de-emphasised for quality service delivery in the hospitals to thrive.

Largely, this study is practical essential as it unearths the irrelevant operations procedure that hinder progress in Nigerian hospitals.

The study accomplishes recognised importance to survey how bureaucracy impedes quality service delivery in government hospitals. This study has provided a vital clue to elements that will bring rapid attention to patients’outcome in Nigerian hospitals and health-care facilities which hitherto has not been emphasised. The study has contributed to the existing body of knowledge associated to healthcare service quality in developing country.

Crises are moments when citizens are beckoning on the political leaders for necessary action. As a president, one is expected to change the narratives during the pandemic that split the world. This analysis aimed at investigating the American government’s response to the critical crisis of COVID-19 and its policy implementation.

The study explored a case point method using a narrative and qualitative analysis to diagnose the USA’s response to the COVID-19 crisis. An exploratory approach was further adopted to finetune the case study report.

The analysis demonstrates that Trump’s power dynamics were weak in the USA and lacked crisis control even as the President that the entire nations of the world were looking up to. The case study report also showed that Trump did not possess the audacity of resilience to manage the crisis. The analysis provides us with how presidential leadership under Trump placed the USA in a state of colossal failure enmeshed with high rates of COVID-19 cases, deaths and unending incapacity to create a fundamental consensus in the fight against the COVID-19 pandemic today. This report shows Trump aged prolonged inability to drive governance mechanisms in the US and illustrated pockets of failures in decision analysis and information dissemination as a leader.

The study revealed how incompetent Trump was in responding to the crisis. This study has provided academia with an understanding of leadership dynamics and behaviour through a Nigerian scholar lens and a sociological perspective.

The need for continuous improvement in the quality of products and services calls for methodology and strategy that will enhance performance in businesses. When there is a reduction in waste during production, it will give room for a better product and services which at the same time improves the profits of the organization. On the other hand, technology is a means by which processes and skills are introduced into the production of goods and services to achieve organizational goals, and this has been proven effective during COVID-19 lockdown. Technology is more of a scientific investigation that brings transformation into business performance, mostly in the manufacturing industry. This study was ventilated through analysis of relevant themes and premised on the narrative discourse of the structures of the study. This chapter examined how Six Sigma, waste reduction methods and technology, brings change and success in the business performance in the manufacturing system. The chapter discusses the impact of technology and the application of Six Sigma in achieving sustainable business processes during COVID-19 in Nigeria's manufacturing system. The study concludes that Six Sigma is a veritable approach to elicit worthy results in any period especially during a pandemic when everything is no longer working perfectly. Six Sigma and disruptive technology have helped the majority of organizations to stay above board in accomplishing their business performance.

Social media came to the limelight in the wake of the early 2000s into the global space to foster interactions among individuals and groups of people. It has shown several positive sides for those who are far off to share vital information across the world, unlike yesteryears when communication seemed difficult for individuals in different locations. This study examines both the positive and adverse impacts of social media on Nigeria's socio-cultural space. It advances how Nigeria utilized social-media platforms during the pandemic and war situation. The study employed narrative discourse to demonstrate crisis communication patterns in Nigeria especially among millennial youths. The narrative discourse portends that there is an indication that social media is both a blessing and a curse to our nation. Often time, people communicate the wrong impression into the polity just to demonstrate their self-serving ideas. They overblow the incidence out of proportion and the majority of the receivers would fail to evaluate the source of the information, messages, and even pictures sent across social media. Most time photoshopped images are sent to prove negative points without having a recuse to the impact of such incidence in society. The chapter offers a vital expository on relevant communication approaches on social media to the audience that will not heat the polity. It examines effective communication strategies and stages of social media crisis management. This paper concludes that the negative effects which it has unleashed on Nigeria are more than its benefits, therefore, a curse rather than a blessing to Nigeria's socio-political and economic space.
