Library Philosophy and Practice (e-journal)

This research article reports the findings of a survey that was conducted at two community colleges affiliated with a large public university system in the Northeast of the United States. A survey was to explore community college students’ citation management help- seeking habits. Findings suggest that respondents were more likely to utilize Purdue University’s Online Writing Lab (OWL) website for reference management help than other resources. The results also show the impact of various factors (i.e., institution, academic level, undergraduate class level, field of study, age, gender, race/ethnicity, and user type) on students’ citation help -seeking practices. Significant statistical associations …

Adoption And Utilisation Of Artificial Intelligence By Librarians In University Libraries In Southern Nigeria, Ogochukwu T. Emiri

Library Philosophy and Practice (e-journal)

The study investigated how librarians working in the various university libraries in Southern Nigeria adopted and used artificial intelligence. The researcher was able to retrieve 704 copies of the 848 questionnaires that were given to the responders. However, the return rate was 83%, which is a respectable amount. The descriptive statistics approach was used to analyse the data that the questionnaire produced. The results showed that there has been little adoption of AI in university libraries in Southern Nigeria. The research also reveals that security scanning devices at university libraries' entrances and exits are the most prevalent AIs, while other …

Learning Feature Embedding Refiner For Solving Vehicle Routing Problems, Jingwen Li, Yining Ma, Zhiguang Cao, Yaoxin Wu, Wen Song, Jie Zhang, Yeow Meng Chee

Research Collection School Of Computing and Information Systems

While the encoder–decoder structure is widely used in the recent neural construction methods for learning to solve vehicle routing problems (VRPs), they are less effective in searching solutions due to deterministic feature embeddings and deterministic probability distributions. In this article, we propose the feature embedding refiner (FER) with a novel and generic encoder–refiner–decoder structure to boost the existing encoder–decoder structured deep models. It is model-agnostic that the encoder and the decoder can be from any pretrained neural construction method. Regarding the introduced refiner network, we design its architecture by combining the standard gated recurrent units (GRU) cell with two new …

A Diversity-Enhanced Memetic Algorithm For Solving Electric Vehicle Routing Problems With Time Windows And Mixed Backhauls, Jianhua Xiao, Jingguo Du, Zhiguang Cao, Xingyi Zhang, Yunyun Niu

Research Collection School Of Computing and Information Systems

The electric vehicle routing problem (EVRP) has been studied increasingly because of environmental concerns. However, existing studies on the EVRP mainly focus on time windows and sole linehaul customers, which might not be practical as backhaul customers are also ubiquitous in reality. In this study, we investigate an EVRP with time windows and mixed backhauls (EVRPTWMB), where both linehaul and backhaul customers exist and can be served in any order. To address this challenging problem, we propose a diversity-enhanced memetic algorithm (DEMA) that integrates three types of novel operators, including genetic operators based on adaptive selection mechanism, a selection operator …

Crowdfa: A Privacy-Preserving Mobile Crowdsensing Paradigm Via Federated Analytics, Bowen Zhao, Xiaoguo Li, Ximeng Liu, Qingqi Pei, Yingjiu Li, Robert H. Deng

Research Collection School Of Computing and Information Systems

Mobile crowdsensing (MCS) systems typically struggle to address the challenge of data aggregation, incentive design, and privacy protection, simultaneously. However, existing solutions usually focus on one or, at most, two of these issues. To this end, this paper presents CROWD FA, a novel paradigm for privacy-preserving MCS through federated analytics (FA), which aims to achieve a well-rounded solution encompassing data aggregation, incentive design, and privacy protection. Specifically, inspired by FA, CROWD FA initiates an MCS computing paradigm that enables data aggregation and incentive design. Participants can perform aggregation operations on their local data, facilitated by CROWD FA, which supports various …

Seven Pillars For The Future Of Artificial Intelligence, Erik Cambria, Rui Mao, Melvin Chen, Zhaoxia Wang, Seng-Beng Ho

Research Collection School Of Computing and Information Systems

In recent years, AI research has showcased tremendous potential to impact positively humanity and society. Although AI frequently outperforms humans in tasks related to classification and pattern recognition, it continues to face challenges when dealing with complex tasks such as intuitive decision-making, sense disambiguation, sarcasm detection, and narrative understanding, as these require advanced kinds of reasoning, e.g., commonsense reasoning and causal reasoning, which have not been emulated satisfactorily yet. To address these shortcomings, we propose seven pillars that we believe represent the key hallmark features for the future of AI, namely: Multidisciplinarity, Task Decomposition, Parallel Analogy, Symbol Grounding, Similarity Measure, …

Seqadver: Automatic Payload Construction And Injection In Sequence-Based Android Adversarial Attack, Fei Zhang, Ruitao Feng, Xiaofei Xie, Xiaohong Li, Lianshuan Shi

Research Collection School Of Computing and Information Systems

Machine learning has achieved a great success in the field of Android malware detection. In order to avoid being caught by these ML-based Android malware detection, malware authors are inclined to initiate adversarial sample attacks by tampering with mobile applications. Although machine learning has high capability, it lacks robustness against adversarial attacks. Currently, many of the adversarial attacking tools not only inject dead code into target applications, which can never be executed, but also require the injection of many benign features into a malicious APK. This can be easily noticeable by program analysis techniques. In this paper, we propose SeqAdver, …

Coordinating Multi-Party Vehicle Routing With Location Congestion Via Iterative Best Response, Waldy Joe, Hoong Chuin Lau

Research Collection School Of Computing and Information Systems

This work is motivated by a real-world problem of coordinating B2B pickup-delivery operations to shopping malls involving multiple non-collaborative logistics service providers (LSPs) in a congested city where space is scarce. This problem can be categorized as a vehicle routing problem with pickup and delivery, time windows and location congestion with multiple LSPs (or ML-VRPLC in short), and we propose a scalable, decentralized, coordinated planning approach via iterative best response. We formulate the problem as a strategic game where each LSP is a self-interested agent but is willing to participate in a coordinated planning as long as there are sufficient …

Are Social Media Users Blindly Following Influencers’ Recommendations On Investing?, Zuliani Dalimunthe, Ananda Chairunnisa, Rachmadi Agus Triono

The Indonesian Capital Market Review

Previous studies show that general information shared by an influencer through social media has been received without sufficient validity testing. However, hardly any study has evaluated whether a stock recommendation by a social media influencer will also be followed blindly. This study evaluates the impact of the credibility of stock influencers on investors’ intention to invest in recommended stocks and whether the relationship can be explained by the perception that the influencer has inside infor- mation or is solely due to fear of missing out (FoMO). This study uses primary data from investors in the Indonesian model market. We collected …

The Intention To Use Mobile Banking As A Financial Technology Service Among Islamic Bank Users, Ratna Juwita, Adam Darma Kusumah, Tiara Syahrani Aqila, Hanan Tsabitah, Muhammad Farhan Syauqi

The Indonesian Capital Market Review

The development of Financial Technology (FinTech) in Islamic banks has not brought increasing us- ers. Therefore, it is necessary to determine which factors influence intention to use FinTech from the demand side or the customers’ side. For this study, we chose mobile banking as our research object, considering that the largest digital transactions in Islamic banks come from mobile banking. Mobile banking also provides banks various benefits to banks such as increased long-term profitability, cus- tomer loyalty, and financial inclusion. The objective of this study is to observe the determinant factor by using the theory of planned behavior (TPB) and …

Financial Innovation And Restriction Hypothesis In The Banking Industry: Evidence From Asean- 5, Yosman Bustaman, Viverita Viverita, Margaretha Tp Lingga, Antonius P. Siahaan

The Indonesian Capital Market Review

This study investigates the financial innovation impact on bank market power in ASEAN banking from 2008 to 2018. It uses income diversification as a representative of financial innovation. The im- pact of countries’ development of financial innovation on market power is measured by the number of ATM, internet, and cellular phone users. The data panel regression model reveals that diversified banks may enjoy higher market power. This result rejects the banking restriction activity hypothesis, which states that a bank that diversifies its income stream results in increased competition. A higher number of available ATMs and more internet users lowers the …

The Impact Of Socially Responsible Human Resource Management (Sr-Hrm) On Sustainable Development In Egyptian Organisations Authors Safaa Shaaban, Safaa Shaaban

Business Administration

In this paper, we introduced the concept of socially responsible human resource management (SR-HRM) and examined the effects of perceived SR-HRM on Sustainable development (SD), a particular area of research that has developed and grown significantly over the past few years, adding to the expanding academic discussion on what is known as "socially responsible human resource management" (SR-HRM) and how it relates to sustainable development. In order to promote sustainable development, the SRHRM discussion aims to proactively improve workers' work experiences and satisfy their social and personal expectations. However, there is no connection between SR-HRM and its impact on SD …

Voices From The Field: Brexit, Citizenship And Agricultural Labour, Richard Yarwood, Gina Kallis, Leonie Boland

School of Geography, Earth and Environmental Sciences

Drawing on a case-study of Cornwall in the South-West of England, this paper has three main aims. First, it seeks to listen to the voices of migrant workers and, in doing so, learn more about their experiences of moving to, and working in, the British countryside. Second, it evaluates the impact of Brexit on their lives and, in particular, how it influences their decision to work in the UK or elsewhere. Finally, consideration is given to the significance of citizenship to their lives, both as a formal contract with the EU and as a lived experience.

Occurrence And Characteristics Of Fibreglass-Reinforced Plastics And Microplastics On A Beach Impacted By Abandoned Fishing Boats: A Case Study From Chellanam, India, N. Manju Lekshmi, Sreejith S. Kumar, P. Muhamed Ashraf, S. P. Nehala, Leela Edwin, Andrew Turner

School of Geography, Earth and Environmental Sciences

Plastics and microplastics have been quantified and characterised at disposal sites of abandoned fishing boats and along the high-water line (HWL) of a fish landing centre in Chellanam, India. Fibreglass-reinforced plastic (FRP) made a greater contribution to the plastic pool at the disposal sites (~ 4.5 n m−2 and 18 g m−2) than the HWL (~ 0.25 n m−2 and < 1 g m−2) and was an abundant component of the microplastic pool at the former. Infrared analysis of micro-sized FRPs revealed various resins (e.g., alkyd, polyester, epoxy), while X-ray fluorescence analysis of the painted surfaces of meso-sized FRPs returned variable concentrations of copper and lead. Concentrations of Pb were high enough to contaminate sand up to ~400 mg kg−1. The relatively high density of FRP and its association with glass fibres and metal-bearing paints results in particles with potentially very different fates and toxicities to more “conventional” (non-composite) thermoplastics.

The African Continental Free Trade Area Negotiations On Rules Of Origin For The Cotton, Textiles And Apparel Sector: A ‘Developmental Regionalism’ Perspective, Faizel Ismail

Journal of African Trade

During the first half of 2022, African trade negotiators of the African Continental Free Trade Area (AfCFTA) were locked in discussions on the appropriate Rules of Origin (RoO) on the cotton, textiles and apparel sectors. Rules of origin are generally utilized as a trade tool to prevent the transshipment of goods from a third country into the preferential trade area. This paper argues that there are different academic and policy approaches to establishing the RoO. On the one hand, policymakers can adopt a narrow trade perspective prioritising the objective of increasing trade efficiency and reducing trade costs for manufacturers. On …

The Impact Of The Covid-19 Pandemic On Exports In Africa: An Approach Based On Fractional Integration, Robert Mudida, Luis A. Gil-Alana, Gema Lopez

Journal of African Trade

This paper examines the influence of the COVID-19 pandemic on exports in Africa. Fractional integration methods were applied to monthly African exports from 26 African countries from January 2011 to December 2020. We observe that the order of integration is found to be statistically smaller than 1 in all except a single country, Angola. For the rest of the African countries, shocks are transitory, showing mean reversion though with a large degree of heterogeneity across the countries, ranging from low levels of persistence with short memory behaviour in Sao Tome and Principle, the Seychelles and Kenya to high levels of …

Intra-Africa Trade In Services And The Afcfta, Socrates Kraido Majune, Judy Kiende Kaaria, Evelyne Nyathira Kihiu

Journal of African Trade

This paper assesses the prospects of AfCFTA – whose implementation commenced in January 2021 – in boosting intra-African trade in services. We use the PPML estimator of the gravity model on bilateral services trade data for total and eight categories of services in 49 African countries spanning from 1995-2019. For our first objective, we assess the determinants of services trade, specifically the degree of complementarity between trade in goods and trade in services. The second objective establishes the role of trade facilitation on trade in services within Africa. We find that goods complement services, particularly total, transport, construction, Other Business …

Potential Impacts Of The African Continental Free Trade Area (Afcfta) On Selected Countries, Kenan Bagci, Abdouramane Diallo, Anisse Terai

Journal of African Trade

This study investigates the potential impacts of the African Continental Free Trade Agreement (AfCFTA) on production and trade in six selected African countries, namely Côte d’Ivoire, Egypt, Guinea, Mozambique, Tunisia and Uganda. In order to estimate the potential long-term effects of the agreement on these countries, the study uses the computable general equilibrium model developed by the Global Trade Analysis Project (GTAP) considering two alternative scenarios: full tariff elimination and partial liberalization. The total GDP of the six countries are expected to be affected at different rates. Overall, countries with a higher initial level of protection tend to see a …

Covid-19 Health Crisis And Cross-Border Trade In West Africa, Tibi Didier Zoungrana, Olivier Combelem, Désiré Drabo

Journal of African Trade

The Economic Community of West African States (ECOWAS) Strict has adopted strict restrictions since the appearance of the new coronavirus disease in 2019 (Covid-19). This article seeks to assess the economic consequences of these measures on the activities of cross-border trade actors. To this end, data was collected from 144 traders, 8 customs services, 9 immigration services and 84 transporters using the quota method, distributed among 6 trade corridors (Ouagadougou-Téma, Dakar-Bamako, Ouagadougou-Abidjan, Lomé-Ouagadougou, Cotonou-Niamey and Lagos-Kano-Niamey). Empirical findings show that on all corridors, the health crisis has led to a decline in trade transactions and hence a decline in net …
