A contextual framework for bibliometric integrity : synthesizing positivist and rationalist paradigms in the analysis of African LIS research during COVID-19.
(Emerald Publishing Limited, 2026-09-15) Lugya, Fredrick Kiwuwa; Nassali, Eliz State
Purpose This paper aims to examine bibliometric analysis’s role in advancing academic integrity through contextual citation practices. It identifies methodological and conceptual gaps in the literature. The paper proposes a philosophically informed novel framework integrating positivist and rationalist paradigms to address these limitations. Design/methodology/approach A multi-phase mixed-methods design is employed, combining a comprehensive literature review, a diagnostic critique of a prior study, and an illustrative case study. The empirical component reanalyses COVID-19’s impact on African Library and Information Science research via triangulated data from Scopus, Google Scholar, journal metadata and author surveys. Findings The diagnostic critique identifies common shortcomings: temporal oversimplification, contextual blindness, data source bias and overreliance on descriptive statistics. The case study demonstrates that applying the contextual framework yields more nuanced insights. Key results show preexisting publishing infrastructure, not the pandemic, primarily drove output, and citation visibility varied significantly across databases. Research limitations/implications While the illustrative case study validates the framework’s utility, broader application across diverse geographic and disciplinary contexts is needed. Future research should test and refine the framework in varied settings to establish its generalizability. Practical implications Researchers should adopt context-sensitive bibliometric practices, including mixed-methods designs, data source triangulation, and consideration of local scholarly infrastructures to support more equitable and credible research assessment, particularly for underrepresented regions. Originality/value This paper provides a novel, philosophically grounded framework synthesizing positivist and rationalist traditions. It offers a critical diagnostic tool and a constructive methodological model, supported by original empirical evidence from an under-researched regional
Land-use and land-cover dynamics in east and the horn of Africa : a regional synthesis of trends, drivers, impacts and interconnected transitions
(Cogent Food & Agriculture, 2026-09-07) Basaliza, Edigar; Musinguzi, Simon Peter; Nagasha, Irene Judith
Land-use and land-cover (LULC) change has become one of the most significant drivers of climate change and environmental transformation globally. In East and the Horn of Africa, several factors have accelerated landscape transformation, yet evidence on regional patterns, underlying drivers, and associated impacts remains fragmented. In view of this, we synthesized a total of 56 existing studies aimed at generating evidence on LULC dynamics across East and the Horn of Africa. Specifically, the review identified dominant land-cover transitions, drivers, impacts and emerging research gaps. The review employed a systematic literature review approach guided by the PRISMA 2020 framework. Peer-reviewed studies published between 1980 and 2024 were identified from multiple databases. Studies were screened using predefined inclusion and exclusion criteria. The findings revealed widespread landscape transformation characterized by forest and woodland decline, wetland degradation, grassland conversion, agricultural expansion, and increasing built-up areas. Agricultural expansion emerged as the dominant proximate driver of LULC change, interacting with multiple underlying factors. The review further identified substantial methodological variation among studies. The review concludes that LULC dynamics in the EHoA are driven by interconnected social economic, institutional and environmental forces. The review recommends need for integrated regional approaches that combine sustainable land management processes that guarantee ecological restoration, livelihood realities and improved land-use governance.
Grouped discrete Hartley transform precoding for low-complexity PAPR reduction in ACO-OFDM visible light communication systems
(Journal of Optical Communications, 2026-09-07) Niwareeba, Roland; Birabwa, Denise Joanitah; Ssemakula, John Bosco
The high peak-to-average power ratio (PAPR) remains one of the major challenges affecting asymmetrically clipped optical orthogonal frequency division multiplexing (ACO-OFDM) systems used in visible light communication (VLC). Although transform precoding techniques such as discrete Hartley transform (DHT) precoding can effectively reduce PAPR, their computational complexity increases significantly as the number of subcarriers increases, limiting practical implementation in large-scale systems. In this paper, a grouped discrete Hartley transform (G-DHT) precoding scheme is proposed for low-complexity PAPR reduction in ACO-OFDM systems. The proposed technique partitions the input symbol vector into smaller groups and independently applies DHT precoding within each group before OFDM modulation. This significantly reduces computational complexity while preserving the PAPR reduction capability of conventional DHT precoding. Simulation results show that the proposed scheme achieves measurable PAPR reduction without noticeable bit error rate (BER) degradation. At a complementary cumulative distribution function (CCDF) of 10−3, the proposed G-DHT scheme with group size G = 128 achieves approximately 0.95 dB PAPR reduction relative to conventional ACO-OFDM while reducing computational complexity by about 50 % compared with full DHT precoding. The results indicate that grouped DHT precoding provides an effective trade-off between PAPR reduction performance and implementation complexity in optical OFDM systems.
Industrial symbiosis and scalability of smallholder farming in Uganda
(Cogent Food & Agriculture, 2026-09-02) Sendawula, Kasimu; Mugarura, Jude Thaddeo; Turyakira, Peter; Alshehri, Reem Fihran; Najjinda, Shamirah; Nakandi, Annet
This study explored smallholder farmers’ perceptions of scalability, the industrial symbiotic practices they undertake, and the contribution of industrial symbiosis to farm scalability in Uganda. A multiple case study design was adopted, involving a purposive sample of 35 smallholder farmers from registered farmer groups in Luwero District, with data saturation reached at the 29th interview. Data were collected through semi-structured interviews conducted in the local language to ensure depth and clarity. It was then analyzed using thematic content analysis to identify key patterns and themes. The findings indicate that smallholder farmers perceive scalability as a multidimensional, practice-based process characterized by increased production, market expansion, efficient resource utilization, and enhanced operational capacity. Scalability is viewed as a dynamic process embedded in everyday farming activities. Industrial symbiosis is practiced through waste reuse, crop-livestock integration, alternative feed production, resource sharing, and knowledge exchange. These practices improve productivity, efficiency, and income, making industrial symbiosis a practical strategy for achieving farm scalability in resource-constrained settings. The study contributes to knowledge by providing a contextually grounded understanding of smallholder farm scalability, moving beyond linear interpretations. It offers empirical evidence on farm-level industrial symbiosis and demonstrates how these practices enhance productivity, efficiency, and adaptive capacity, providing novel insights into how resource-constrained farmers in Uganda achieve scalability.
Human resources training and development, value creation, and employee performance in the public service
(Cogent Business & Management, 2026-08-27) Wanyama, Seperia Bwadene; Eyamu, Samuel; Muganga, Christopher; Ndanyi, Davis Malowa; Sansa, Agnes
This study examines the relationship between human resource training and development (HRTD), involving training (HRT) and employee development (EMD), and employee performance in Uganda’s public service, focusing on the mediating role of human resource value creation (HRVC), comprising perceived HR strategic role and HR service quality. Using an explanatory quantitative survey, data were collected from 416 respondents across three ministries and seven local governments. Established measurement scales demonstrated strong reliability (Cronbach’s α = 0.820–0.885), while exploratory and confirmatory factor analyses supported construct reliability and validity. Data were analysed using descriptive statistics, Pearson correlations, hierarchical regression, and PROCESS bootstrapping. The findings indicate that training, employee development, perceived HR strategic role, and HR service quality are positively associated with employee performance. HRTD dimensions were also significantly associated with HRVC dimensions. Furthermore, perceived HR strategic role and HR service quality partially mediated the relationship between HRTD and employee performance. Drawing on Human Capital Theory, the Harvard HRM model, and the Resource-Based View, the study demonstrates how HRTD contributes to employee performance through HR value creation. The findings underscore the importance of strategic, value-driven HRTD systems that strengthen employee capabilities, HR service quality, and public sector performance.45
