Development of a disaster response plan at a national level is regarded as the best way to undertake country-level disaster management in a well-coordinated manner, involving all stakeholders in well-built networks. Where developed national disaster response plans (NDRPs) are to be subjected to evaluative assessments from time to time to establish their strengths and weaknesses in disaster response processes. Only about 20 of the world's 195 countries have NDRPs, and only three of them have undergone some form of evaluation. This paper contributes toward filling this gap by evaluating the NDRP of the Federal Republic of Nigeria. Lessons from the implementation of this NDRP will help guide the development of the plans in countries where they do not yet exist.

Network and qualitative content analysis was employed to subject the Nigerian NDRP to critical evaluation using standards already established in the literature for the development of management networks and their use in disaster response. The experiences of other countries with developed NDRPs were also used to guide an effective evaluation process.

Findings of the study show that the Nigerian NDRP is deficient in many respects, particularly in the areas of weak development of networks, absence of roles-differentiation for various stakeholders, lack of specified achievable and hence monitorable targets, objectives and outcomes and absence of detailed response plans for specific disaster types. The plan needs to therefore be subjected to a detailed multidisciplinary and multi-stakeholder review to get it strengthened.

This is the first attempt to conduct an evaluative assessment of Nigeria's NDRP and the 4th in the world. The study's findings can help not only to strengthen Nigeria's NDRP, but also to develop similar plans in other countries around the world.

Evidence abounds on surging disasters, mainly as consequences of poor risk identification and management, which have historically accompanied disaster management in many African countries. Effective management of disaster risks, whether natural or man-made, is necessary for building resilience, enhancing mitigation, preparedness, response, recovery and adaptation. As part of a broad-based risk management approach, Nigeria made frantic efforts to mitigate the effects of various disasters, by establishing relevant institutions and formulating policies. In spite of these efforts, implementation outcomes have not been adequately quantified and managed. This study reviews and assesses the policies and practices of disaster risk management (DRM) vis-á-vis institutional framework in Nigeria. It utilises available data and policy documents to review and analyse Nigeria’s institutional framework. Furthermore, the study carries out implicative scenario analysis based on the current institutional framework, to match the DRM trends. It also proffers recommendations on how best institutions could drive proper DRM in Nigeria. The strengths, opportunities, gaps and constraints associated with disaster and risk reduction in Nigeria are then highlighted.

Contamination of the environment by heavy metals is a phenomenon of global importance today. When present in high concentrations in the environment, heavy metals may enter the food chain from soils and result in health hazards. Accumulation in street dust is one major way through which heavy metals may find their way into soils and subsequently living tissues of plants, animals and human beings. In this paper, the magnitude and sources of some heavy metals (Cu, Mn, Fe, Cd, Pb and Zn) in street dust samples in and around Gwagwalada, Nigeria, were assessed.

Street dust samples were collected from 12 sites with and without varying levels of human activities (blacksmithing, motor repair works, metal working and fabrication, vehicular traffic and residential development) in the area and analysed by atomic absorption spectrophotometry to determine the magnitude and sources of accumulation of the above heavy metals in street dust in the study area.

The mean concentrations were found to be 210, 79, 97, 3.9, 120 and 96 μg g⁻¹ respectively, for Pb, Zn, Cu, Cd, Fe and Mn across the various sampling sites. Samples collected from sites with human activities were found to contain concentrations of the metals that are generally higher than those in background areas (without human activities). However, metal working and fabrication, and motor repair works were found to have a stronger influence on the accumulation of the metals in the dust samples than vehicular traffic.

The results indicate that, contrary to what is expected, based on the observations made in several areas by many researchers elsewhere, metal working and fabrication, and motor repair works have a stronger influence on the accumulation of the metals in the dust samples than vehicular traffic in the study area.

Provides information on heavy metal contamination of the environment in an area of Nigeria.

This paper seeks to examine the concentration of selected heavy metals (Cr, Pb, Cd, and Ni) in oil‐polluted soils of two communities in Warri, Delta state, Nigeria.

Soil auger samples were collected at a depth of 0‐15 cm from four sites. Two soil samples were collected from two sites observed to have had oil spills and also two samples from two sites without oil spillage. The soil samples were analysed using the UNICAM 969 Atomic Absorption Spectrophotometer to determine the level of concentration of the heavy metals in these sites. Their levels in the oil‐spilled sites are compared with those of the control sites and also with the European community standards.

The results obtained from this study reveal that the concentration of the heavy metals considered were higher in the oil‐spilled sites relative to the control sites. Similarly, when compared with the European community standards, the concentration is said to be quite significant.

The results indicate that the operations of the oil industry in the study area have not been sufficiently accompanied by adequate environmental protection. To safeguard agricultural land in the area and hence human health, there is an urgent need for government to address the incidence of oil spills in this area.

This paper provides information on the contribution of the oil industry in heavy metals contamination in the Niger‐Delta area of Nigeria.

The purpose of this paper is to explore use of the Theory of Constraints (TOC) approach in addressing traffic congestion as the main impediment to improving utility of the land transportation systems. The observed element is a motorway segment with regulated access.

As the literature addressing this topic is rare or nonexistent, this study employs exploratory design, developing tentative theory through the generation of new ideas and assumptions forming grounded picture as a base for further investigation.

The study concludes that the most binding constraint is broken in the third out of the TOC’ five steps and that the improvement in the given segment of the land transportation system is possible to be achieved using this framework.

Although the merits of use of TOC have been considered in other than just production-planning environments, its application in land transportation systems has never been examined. This study presents one of the rare, if not the only attempt to make use of this unique theory that is systematised in the systems management paradigm within the realm of land transportation systems.

The purpose of this study is to collaborate with environmental engineering and management making an effort to provide evidence for the irresponsible behavior of small business set up in north India with special reference to Aligarh City. Corporates have huge accountability for sustainable development, and they cannot overlook the major responsibilities which are lying on their shoulders. CSR is related to the concept of “doing good” but, beyond “doing good” businesses have the responsibility for “avoiding bad” to avoid corporate social irresponsibility (CSI), such as damaging the environment by polluting land, water and air, cheating customers, violating human rights, or doing any unethical practices.

In this study, random groundwater samples were collected from “Aligarh Nagar Nigam” installed hand pumps from industrial influence areas of Aligarh during the month of October and November 2017. These samples were collected nearby small-scale metal plating industries plants. The samples analyzed by the Atomic Absorption Spectrometer (AAS) Perkin Elmer PinAAcle 900 F, for Fe, Mn, Pb, Zn, Cu and Cr (Jahromi et al., 2007; Chen and Teo, 2001; Bidari et al., 2007; Land and Hoops, 1973; de Oliveira et al., 2016; Akoto et al., 2016). In addition, some other parameters also taken in this study and the results obtained are compared with the World Health Organization (WHO) and Bureau of Indian Standard (BIS).

These results of the study revealed that the penetration of heavy metals like Cr, Pb, Cu, Zn, Fe and Mn into the soil is found much higher than the permissible limit stated by the government. The concentrations of metals in groundwater found to be within limits, but some metals are exceeding the standard limits in few samples. Concentrations of these heavy metals Cr>Cu>Pb>Fe>Mn are exceeding standard limits, Zn found within permissible limits as per WHO and BIS standard. This result proves to be a means to an end for an irresponsible behavior toward the society and environment which leads to serious health and environmental hazards.

The results are beneficial for data generation on various quality parameters of groundwater. The results of this study help in proper decision-making by concerned authorities to prevent, reduce toxic levels and begin to take steps for making water fit for drinking and other purposes. The research is limited in Aligarh City and other cities are like Kanpur, Noida and Ghaziabad are also tested by taking samples of water, as these cities are extensively captured by SME’s and large scale industries.

The results of this study have several implications for both governmental and non-governmental practice and policy development. As society expects positive attitudes of the businesses toward CSR activities and concern about the environment, businesses, institutions and governments should pay more attention to promote the initiative of environment safety to intensify their public concern. The small business unit must know about the serious health hazards of discharging the waste water in the open and therefore regular checking of heavy metal contamination in the groundwater in these areas is needed and use of contaminated water must be prevented to lessen the health risk caused by using the metal contaminated groundwater. The small-scale industries should follow the guidelines for proper disposal of wastewater discharge. The water treatment technology should involve and take possible steps to remove heavy metals contamination.

This study provides real data to municipality and other government offices which can be used as a benchmark to plan strict policy to prohibit the open discharge of wastewater by industries.

A boundaryless career perspective suggests that career competencies are essential for employees who wish to advance their careers in high uncertainty. This study aims to propose an integrated conceptual model for career competencies to provide insights for employees and organizations by identifying what and how one can prepare and provide support for career development in an uncertain and complex work environment.

The integrated literature reviewed was adapted to provide a conceptual model for career competencies. All 77 studies were reviewed, guided by the intelligent career theory (ICT) and social cognitive career theory (SCCT).

The mechanisms of career competency development were examined through the interrelationship between three types of knowing; knowing-why, knowing-whom and knowing-how. Career competencies can be considered a developmental process, therefore, they could develop through various interventions and accumulate over time. Especially the results indicate that learning is an essential component of career competencies, as it increases self-efficacy and promotes a desire to achieve positive career outcomes.

This study provided a conceptual model, explored the mechanisms of career competency development and considered how career competencies influence career outcomes. Furthermore, it identified the context of the construct of career competencies by integrating the SCCT and ICT. Finally, it showed the inadequacy of existing research on negative factors of career competency outcomes and recommended further research to broaden the general context of career competency studies.

This study aims to investigate the influence of creativity and resource availability on career competencies (CC) and career success (CS) of entrepreneurs in Nigeria using the intelligent career framework.

Data was obtained using answers to questionnaires given to 348 successful entrepreneurs. The data was analysed using non-parametric software (Smart-PLS).

The results indicate that entrepreneurs who possess “know-why”, “know-how” and “know-whom” can access the required resources and are doing well in their careers. It is suggested that these competencies were significantly related to entrepreneurial CS. Resource availability moderates the relationship of knowing-how, knowing-why competencies and CS, whilst creativity moderates only the link between knowing-whom and entrepreneurial CS.

The results help us to comprehend better the nature of successful entrepreneurial careers and the prominent role of tripartite competencies in achieving a successful career. Also emphasised here is the prominence of a more holistic perspective of these components based on a mix of social, motivational and human capital.

These findings hinted that entrepreneurs should pay uniform consideration in fostering each CC. There are implications for career advisers, practitioners and entrepreneurship programmes.

To the authors’ best knowledge, this is first-of-its-kind research that used primary source data in understanding CC – “knowing-how, knowing-whom and knowing-why” – with entrepreneurs’ CS in Nigeria.

The purpose of this paper is to examine the effect of grit (consistency of interest and perseverance of effort) on entrepreneurial career success (career satisfaction, perceived career achievement and perceived financial attainment) through the role of resilience.

The study was cross-sectional, and the data were collected using questionnaires from 111 entrepreneurs in Nigeria who have been in business for over five years and were selected using purposive sampling technique. The study used Smart-PLS to assess the measurement and structural model.

The perseverance of effort was related to all the aspects of career success as well as resilience. But consistency of interest was positively related to only perceived financial attainment. It also predicted resilience. Resilience was also related to all the facets of career success. All three mediation hypotheses were supported.

The study delivered fascinating understandings into the structures of grit. The Western conceptualisation of grit may not be valid in a collectivist society where consistency is not that very much considered.

The study helps to further validate grit in the entrepreneurship field; the construct is a facilitator of entrepreneurial action and an indispensable source of energy that can revitalise the entrepreneur along the arduous road to success.

The two components of grit can have a dissimilar influence on different outcomes – as prior investigations, although recognising that the two components are conceptually dissimilar, have rarely studied them so empirically.

Although the innovative behaviour of public employees is critical for the creation of public value and meeting of public interests, the authors are uncertain about the role of the human resource (HR) system in affecting individual behaviour as past studies tended to discuss innovation at the organisational level of analysis. Based on corporate human resource management (HRM) literature, the authors draw from the ability-motivation-opportunity (AMO) model to examine the influence of innovation-based HR practices on work-related risk propensity and innovative behaviour and the moderating role of perceived error tolerance of public sector organisations.

Dyadic data were collected from supervisors and their subordinates in various public sector organisations in the UAE. The authors collected valid responses from 100 managers and 200 employees.

This study's findings demonstrate that the HR system in the public sector shapes employees' behaviour at the individual level of analysis, consistent with the corporate HRM literature. The authors reveal that innovation-based HR practices significantly promote employees' innovative work behaviour because they trigger their inclination and disposition to take risks. Furthermore, the authors provide evidence that such risk-taking propensity at work is heightened under the conditions of a high level of error tolerance by the organisational management.

This study's findings point out the importance of implementing innovation-based HR practices, such as recruitment, reward and training, to drive public sector employees' innovative work behaviour as they could galvanise their risk-taking propensity and, subsequently, innovative behaviour. Public sector managers also need to develop an innovation culture tolerant toward employees' mistakes to further foster employees' work innovativeness. Policy wise, this study's findings could be integrated into the national innovation strategy to drive the national growth in the UAE.

This study sheds light on the drivers behind innovative behaviour among public employees, which is a less researched area, especially in a non-Western context.
