Abstract

Purpose

Many recommender systems are generally unable to provide accurate recommendations to users with limited interaction history, which is known as the cold-start problem. This issue can be resolved by trivial approaches that select random items or the most popular one to recommend to the new users. However, these methods perform poorly in many cases. This paper aims to explore the problem that how to make accurate recommendations for the new users in cold-start scenarios.

Design/methodology/approach

In this paper, the authors propose embedded-bandit method, inspired by Word2Vec technique and contextual bandit algorithm. The authors describe user contextual information with item embedding features constructed by Word2Vec. In addition, based on the intelligence measurement model in Crowd Science, the authors propose a new evaluation method to measure the utility of recommendations.

Findings

The authors introduce Word2Vec technique for constructing user contextual features, which improved the accuracy of recommendations compared to traditional multi-armed bandit problem. Apart from this, using this study’s intelligence measurement model, the utility also outperforms.

Practical implications

Improving the accuracy of recommendations during the cold-start phase can greatly raise user stickiness and increase user favorability, which in turn contributes to the commercialization of the app.

Originality/value

The algorithm proposed in this paper reflects that user contextual features can be represented by clicked items embedding vector.

Abstract

Purpose

Banditry and terrorism constitute serious security risks in Nigeria. This follows the fact that Nigeria is rated as one of the leading states in the world that is plagued by terrorism. Terrorists and bandits usually embark on predicate crimes such as kidnapping, smuggling, narcotics trade, and similar trades to finance their terrorist enterprises in Nigeria. The funds realized by criminals from nefarious sources such as sales of narcotics and ransom from kidnapping are usually laundered to make their criminal enterprises self-sustaining. Thus, all “dirty” money is laundered so as not to attract the attention of law enforcement agents. The funds realized through receipt of ransom from kidnapping, smuggling or funds from sponsors are laundered through channels such as bureau de change, which are difficult to monitor by the Nigerian authorities due, in part, to flaws and loopholes in the current anti-money laundering and anti-terrorist laws. This paper aims to adopt a doctrinal and qualitative desktop research methodology. In this regard, the current anti-money laundering and anti-terrorist laws are discussed to explore possible measures that could be adopted to remedy the flaws and loopholes in such laws and combat money laundering and financing of terrorism in Nigeria.

Design/methodology/approach

The article analyses the regulation and combating of money laundering and terrorist financing activities in Nigeria. In this regard, a doctrinal and qualitative research method is used to explore the flaws in the Nigerian anti-money laundering laws so as to recommend possible remedies in respect thereof.

Findings

It is hoped that policymakers and other relevant persons will use the recommendations provided in this article to enhance the curbing of money laundering and terrorist financing activities in Nigeria.

Research limitations/implications

The article is not based on empirical research.

Practical implications

This study is important and vital to all policymakers, lawyers, law students and regulatory bodies in Nigeria and other countries globally.

Social implications

The study seeks to curb money laundering and terrorist financing activities in Nigeria.

Originality/value

The study is based on original research which is focused on the regulation and combating of money laundering and terrorist financing activities in Nigeria.

Abstract

Purpose

There is a noticeable dearth of literature offering Marxist perspectives and analyses on the Bangsamoro struggles for self-determination, ethnic and religious identities and social justice. A reason for this may lie in the general derision of bourgeois academics and conventional commentators on the supposed paucity of Marxist theories on nationalism, ethnicity and religion. This may have influenced, ironically, Filipino Marxist thinkers into being indifferent to this research topic. Far from the truth, however, that Marxism is essentially an economic determinist social conflict theory, its historical materialism offers a rich treasury of analyses and perspectives on nationalism, self-determination, religion and ethnic identity within the context of class struggles as the acme of the theory of scientific socialism. The paper, therefore, offers a scientific analysis of the Bangsamoro Question from a Marxist standpoint beyond the perspectives of psychologism, naturalism and ethno-racialism, which are usually deployed by traditional and uninformed commentators in analyzing ethnicity questions and quests for separatism.

Design/methodology/approach

The paper employs the historical and class analysis of the dynamics, relationships and struggles of classes in the history of the Bangsamoro struggles against colonialism and the subsequent postcolonial regimes up to the present time.

Findings

As a scientific paradigm, historical materialism presents itself as a general scientific social conflict theory. Using this framework through historical and class analyses, the paper proves the improbability of the Moros’ quest for separatism or genuine autonomy at this historical point. It, therefore, asserts the linking of the Moro struggles to the more immense struggles of the Filipinos for national and social liberation from imperialism.

Research limitations/implications

The paper is limited to the historical and class analyses of classes’ dynamics and struggles. It is, therefore, far from an exhaustive analysis of the Moro struggles using different non-Marxist social conflict theories.

Practical implications

The research can be considered a practical guide in analyzing and predicting the trajectories of the Moro struggles in Mindanao and Sulu.

Social implications

The work addresses the question from radical and Marxist premises.

Originality/value

This is a highly original and valuable work from the point of view of Marxist social conflict theory.

Abstract

Purpose – The purpose of this study is to analyze and design a virtual collaboration information system of the Jamu supply chain network based on a fair adaptive contract to respond to stability challenges in business with an uncertainty environment condition.

Design/Methodology/Approach – System entity approach is used for the purpose of system analysis and then case, sequence diagram, class diagram, graph data modeling, and business process modeling and Notation verse 2 (BPMN2.0) are also used to design the system concept. Each process of the connecting event and gateways was arranged with relevant multicriteria decision approach, whilst an adaptive quantitative formulation based on prescriptive analytics was embedded to ensure a fair contract implementation during the terms for all sphere roles in supply chain.

Findings – The results and implications of this model emphasizes on the knowledge, competence, trust, and fair (KCTF) for actors’ adoption to improve supply chain stability and implementation.

Practical Implications – This led actors to collaborate their business in a more effective way.

Originality/Value – This model can reach more stability in the uncertainty environment.

Abstract

Purpose

We study five exogenous shocks: climate, violence, price hikes, spoilage and the COVID-19 lockdown. We analyze the association between these shocks and trader characteristics, reflecting trader vulnerability.

Design/methodology/approach

Using primary survey data on 1,100 Nigerian maize traders for 2021 (controlling for shocks in 2017), we use probit models to estimate the probabilities of experiencing climate, violence, disease and cost shocks associated with trader characteristics (gender, size and region) and to estimate the probability of vulnerability (experiencing severe impacts).

Findings

Traders are prone to experiencing more than one shock, which increases the intensity of the shocks. Price shocks are often accompanied by violence, climate and COVID-19 shocks. The poorer northern region is disproportionately affected by shocks. Northern traders experience more price shocks while Southern traders are more affected by violence shocks given their dependence on long supply chains from the north for their maize. Female traders are more likely to experience violent events than men who tend to be more exposed to climate shocks.

Research limitations/implications

The data only permit analysis of the general degree of impact of a shock rather than quantifying lost income.

Originality/value

This paper is the first to analyze the incidence of multiple shocks on grain traders and the unequal distribution of negative impacts. It is the first such in Africa based on a large sample of grain traders from a primary survey.

Abstract

In this chapter, I explore two media texts, Imtiaz Ali's Highway and Alankrita Shrivastava's Netflix original series Bombay Begums (2021). I contend that recent filmmakers have begun to arguably reframe the narratives of rape victim-survivors and disrupting the cultural of silence described above. They offer progressive and multi-faceted representations of these experiences, such that there is an opportunity for a dialogue within both private and public spheres. What I mean when I say that they are ‘progressive representations’ is that the rape victim-survivors are not merely reduced to helpless women in distress, nor painted as vengeful, aggressive characters. Instead, their characterisation shows that they have agency and autonomy, but at the same time struggle with the repercussions of speaking out against their perpetrators in a society that does not support them wholly.
