The growing volume of trade misinvoicing in Sub-Saharan Africa (SSA) calls for serious concern, particularly given its effect on macroeconomic fundamentals. Despite the growing body of literature on the growth effect of trade misinvoicing, empirical evidence on the role of governance in moderating the effect is quite scarce, particularly for SSA. The purpose of this paper is to provide insights into the growth effect of trade misinvoicing in SSA as well as the moderating role of governance in this regard.

The feasible generalised least square estimator was applied to analyse relevant data, spanning 2009–2018, of 35 SSA countries. Governance indicators were classified into economic, political and institutional governance, and their individual role in moderating the nexus between trade misinvoicing and economic growth was explored.

This paper showed the presence of cross-sectional dependence among SSA countries and long-run convergence of the estimated variables. The empirical finding showed that trade misinvoicing has a negative growth effect in the selected SSA countries, but both economic and political governance are crucial in lowering the observed negative growth effect.

To curtail trade misinvoicing, SSA policymakers should go beyond just designing anti-money laundering policies to effectively implementing the policies for improved growth prospects. More so, the government of each SSA country must devise means of strengthening governance and building effective, accountable and transparent institutional frameworks that will constantly check and discourage trade misinvoicing activities.

The originality of this paper stems from its novel assessment of the role governance plays in moderating the growth effect of trade misinvoicing in SSA using the feasible generalised least square estimator. It also details the strategies needed to effectively tackle trade misinvoicing.

The study evaluated the introduction of naltrexone in an Australian prison system for imprisoned male heroin users. Treatment outcomes were analysed for two sub‐samples taken from an unsuccessful randomised controlled trial. The first sample comprised 68 participants who were randomly allocated to naltrexone treatment. The second sample comprised 47 participants who commenced opioid pharmacotherapy during the study period. Thirteen per cent of subjects started naltrexone, with only 7% retained in treatment at six months. Six‐month retention was significantly lower in naltrexone compared to methadone (p = 0.0007). Poor patient acceptability and retention did not support oral naltrexone maintenance in this treatment group.

The materials included in this column were selected on the basis of an item by item review of all government publications received at a major depository library. Emphasis is placed on tools of a reference format, although much else that the Federal government publishes is otherwise of high referral value. Publications not in a reference format, in the strictest sense, are included when their potential value dictates; brief entries for “how to” items and informative pamphlets are also given if deemed potentially useful, particularly for school and public libraries and wherever the identification of vertical file materials is the responsibility of the public service librarian. Documents librarian's shorthand has been used in the bibliographical citations. Wherever possible, “United States” has been understood rather than stated in the corporate entries; also, the GPO imprint and place have been dropped. All items unless otherwise indicated are available from the Superintendent of Documents at the prices given. Prices which do not appear were not available at the date of review.

The purpose of this paper is to report the problems which the library management at the National Institute for Nigerian Languages (NINLAN) encounter in accessing and utilizing library intervention money from the Education Trust Fund (ETF) in Nigeria.

The paper discusses problems experienced by NINLAN Library, including: inadequate period specified for retirement of utilized funds, delay in securing approval for new projects, effort of some members of committees to influence award of contracts, and absence of librarians in most ETF project committees.

The management of NINLAN Library, educational institutions in Nigeria and ETF, should be proactive in planning for development programmes, and articulating projects to be funded by the ETF. There should be clear guidelines for accessing, utilizing and retiring the funds approved for different projects.

The paper offers suggestions to alleviate the problems. These include increasing in the allocation of library intervention funds, extending the period for utilization and retirement of project funds, and inclusion of librarians in various committees for library intervention projects.

The financial market offers an intricate laboratory for the study of consumer behavior. One area that has received little attention in the finance literature and that could benefit from insights from consumer behavior research is the relationship between gender and consumer investment preferences and practices. The primary goal of the present study is to explore the influence of consumers' gender on their investment behavior. The study examines the investment strategies of male and female investors using psychometric measures and self‐reporting of investment behavior.

This research examines the long-run relationship between microfinancial inclusion and poverty alleviation in Nigeria from 1990 to 2018.

the Engle–Granger two-step co-integration and autoregressive distributed lag (ARDL) techniques. Gross domestic product (GDP) per capita proxies poverty reduction. Number of microfinance banks, borrowers of microfinance institutions, commercial bank branches, commercial bank loan to small-scale businesses and broad money supply ratio measure microfinancial inclusion.

The results indicate a long-run relationship between microfinancial inclusion and poverty reduction. The error correction model reveals that microfinancial inclusion and poverty alleviation converge to long-run equilibrium. The number of microfinance banks, lagged value of borrowed funds and broad money supply negatively influences poverty while the lagged values of number of microfinance banks and broad money supply positively influence poverty.

Effective ways to improve microcredit channels and liquidity flow to the poor through a microfinance bank's intermediation should be promoted by the Central Bank of Nigeria (CBN) using an aggressive policy, which provides access to credit to the poor.

Theoretically, microfinance institutions should increase credit to the poor, especially in rural areas at moderate cost. This study further suggests that many microfinance bank branches should be located in urban and rural areas targeting the poor.

Microfinancial inclusion reduces population's poverty in Nigeria and globally.

Contrary to other studies, this paper utilizes number of microfinance institutions and borrowers of microfinance institutions to examine the relationship between microfinancial inclusion and poverty alleviation in Nigeria.

One of the most pervasive economic crimes in the world today is money laundering. It has been estimated that some $2 to $3.6 trillion of hot money is laundered through the financial market each year. Such huge amounts of money cannot be successfully laundered without the involvement of financial intermediaries (such as bankers and lawyers) who used their expertise to conceal and obscure illegal activity. However, broader accounts of the role of financial intermediaries in corrupt practices are relatively scarce. The purpose of this paper is to examine some predatory activities of financial intermediaries in facilitating money laundering practices in Nigeria.

The paper locates the role of financial intermediaries within the sociological theory of profession to argue that these professionals facilitate money laundering despite their professional and ethical claims. The paper uses publicly available evidence to illuminate the role played by financial intermediaries in elite money laundering.

The evidence shows that, in pursuit of organisational and personal interest, the financial intermediaries create enabling structures that support illicit activities of political and economic elite in Nigeria. The paper concludes that the establishment of money laundering laws and the creation of anti‐money laundering agencies had not brought about professional transparency and ethical conduct.

The paper therefore suggests that Nigeria needs to reform its financial institutions to promote integrity, accountability and ethical professional conduct to curb money laundering and to build trust in the Nigerian financial system.

The social, economic and political effects of financial intermediaries' anti‐social practices are significant as huge amounts, often dwarfing the gross domestic product (GDP) of many nation states, are involved. These questionable practices by financial intermediaries increase profits, but harm citizens.

The paper is a general review of literature and evidence on contemporary issues.

This study aims to better understand the effects of speeches as a valuable communication tool for central banks. It extends the analysis of the effects of public speeches on jumps to determine whether individual speakers matter partly because of their name, position or institution.

This study detects intraday jumps using a robust-to-jump volatility estimator that accounts for deterministic seasonality. As a result, this study removes spurious jumps that occur when volatility is high and consider the relatively small jumps that occur when volatility is low. After identifying jumps, this study examines their reactions to senior official speeches and macroeconomic news surrounding the US and European Union (EU) financial crises.

Despite having the most influential individual speakers, this study finds that the impact of the Federal Reserve (Fed) and European Central Bank (ECB) is mitigated because the two institutions have a relatively small impact on currency jumps. This finding shows that the speaker’s name is more important than his or her institution affiliation. While the Federal Reserve Bank President and Chief Executive, as well as ECB board members, significantly reduce jump sizes, particularly during the EU crisis period, both the Fed Chairman and the ECB President increase the magnitude of the jump in both the US crisis and noncrisis periods, contributing to market instability.

The implications of the results include international portfolio management, currency derivatives pricing and hedging, risk management and market efficiency.

The findings contribute to a better understanding of the effects of senior official speech attributes on currency jumps in various economic states. The results raise questions about the speaker’s name, institution and position’s effectiveness in calming markets and reducing uncertainty.

The paper aims to describe ideas and implementation of the computer tool for computer‐aided and recycling‐oriented design. Currently, there is a strong tendency to take into account the impact of a product on the natural environment. The authors concentrated on the issue of the recycling process of the product, taking into account the phase of its design. The purpose, structure, technology and example results are presented in this paper.

It was assumed that analysis will be performed based on a set of measures of a product. These measures (developed by the authors), describing the product from the recycling point of view, are calculated automatically, according to the changes (variants) in the product's model. The presented tool is based on agent technology. The structure of the system – the agents, its roles and communication between them – has been described.

The main achievement of the work presented in this paper is the method supporting eco‐design based on agent technology. Based on the analysis of the process of recycling‐oriented eco‐design, the authors designed and then implemented the tool that aids designers' activities in the area of eco‐design. The drawn‐up method supports decision making concerning designing environmental‐friendly products. Thanks to agent technology, the design process can be conducted in the distributed design environment.

The usage of the presented computer‐aided and recycling‐oriented system during the design process requires the duplication of some of the engineer's work. The analysis is performed within the presented tool, outside the typical contemporary design environment, such as CAD 3D systems. As a consequence, there is a need to enter the product structure into the described system, which can be inconvenient. The further work of the authors assumes implementation of this concept into a CAD 3D system.

There has been a limited amount of research work regarding application agent technology in the field of end‐of‐life oriented design. The structure of the system, the measurements and idea of extension of product structure are the original results of the work. The results could be implemented into commercial computer‐aided design systems, especially into its PLM (product lifecycle management) group, due to the weak representation of end‐of‐life phases in these tools.

When comparing novel centralized and distributed communications and video streaming services, the authors identified a need for a theoretic framework to position a multitude of ICT services and technologies according to their value proposition. Literature does not integrate existing value analysis concepts into a holistic theoretical framework. This paper aims to address this shortcoming by proposing a value analysis framework for ICT services capable of describing the value exchanges between different actors and their role constellations based on technological componentizations.

The paper evaluates a representative selection of communications and video streaming services and an extensive literature study on existing value analysis research was conducted to develop the framework and to verify it.

The paper demonstrates the applicability of the value analysis framework in communications and video streaming case studies, which are technically very different from each other but, at the abstraction level the framework provides, display very similar characteristics in value flows and role constellations.

The value analysis framework could be extended and verified with other case studies and complemented with quantitative modeling and system dynamics.

The authors combine existing literature into a proposal of a holistic value analysis framework and apply it to novel centralized and distributed communications and video streaming services. Both academics and practitioners can use the framework to evaluate the value proposition of ICT services and technologies.
