• Mendeley reader counts for US computer science conference papers and journal articles

      Thelwall, Mike (MIT Press, 2019-12-31)
      Although bibliometrics are normally applied to journal articles when used to support research evaluations, conference papers are at least as important in fast-moving computingrelated fields. It is therefore important to assess the relative advantages of citations and altmetrics for computing conference papers to make an informed decision about which, if any, to use. This paper compares Scopus citations with Mendeley reader counts for conference papers and journal articles that were published between 1996 and 2018 in 11 computing fields and had at least one US author. The data showed high correlations between Scopus citation counts and Mendeley reader counts in all fields and most years, but with few Mendeley readers for older conference papers and few Scopus citations for new conference papers and journal articles. The results therefore suggest that Mendeley reader counts have a substantial advantage over citation counts for recently-published conference papers due to their greater speed, but are unsuitable for older conference papers.
    • A graphical tool for assessing the suitability of a count regression model

      Wilson, Paul; Einbeck, Jochen (Österreichische Statistische Gesellschaft (Austrian Society for Statistics), 2019-12-31)
      Whilst many numeric methods, such as AIC and deviance, exist for assessing or comparing model fit, diagrammatic methods are few. We present here a diagnostic plot, which we refer to as a ‘Quantile Band plot’, that may be used to visually assess the suitability of a given count data model. In the case of diagnosed model inadequacy, the plot has the unique feature of conveying precise information on the character of the violation, hence pointing the data analyst towards a potentially better model choice.
    • Bruxism and psychotropic medications

      Antoun Reyad, Ayman; Girgis, Eriny; Ayoub, Amin; Mishriky, Raafat (Wiley, 2019-12-31)
      Mental Health Disorders including schizophrenia, bipolar and schizoaffective disorders are often treated using psychotropic medications with evidence that some of these medications such as antipsychotics could be associated with significant oral side-effects. In this comprehensive review, we examine the psychotropic medications mechanisms of action and their oral side-effects, with specific focus on psychotropic medications and bruxism as a major oral health complication with a negative impact on the quality of life of mental health sufferers, relevant to psychiatrists, dentists and general practitioners. Bruxism could be caused by the antipsychotics extrapyramidal side-effects through dopaminergic receptors. Bruxism as a side-effect of psychotropic medications could result in significant consequences to oral health such as tooth structure destruction and irreversible harm to the temporomandibular joint. The review findings could assist in understanding the aetiology of bruxism, establish appropriate management plan, while supporting psychiatrists and dentists to detect temporomandibular dysfunctions (TMD) such as bruxism.

      Suresh Renukappa, Suresh; Suresh, Subashini; Al Nabt, Saeed; Sarrakh, Redouane; Algahtani, Khaled; Hessami, Ali (IntechOpen, 2019-12-31)
      The Kingdom of Saudi Arabia (KSA) government aims to reduce fiscal deficit by improving efficiency, reducing costs, as well as its subsidies. This often calls for the creation, use and exploitation of new knowledge. Therefore, knowledge assets must be properly managed to provide an environment for well-informed decisions. The aim of this chapter was to investigate the critical success factors (CSFs) for effective implementation of KM strategies in the KSA public sector organisations. Qualitative results were derived from semi-structured interviews with 42 public sector directors and managers to gain insights into the topic being investigated. As revealed in the study, the CSFs for effective implementation of KM strategies are broad, but nine key CSFs stand out. The association between the identified factors is established by employing an interpretive structural modelling (ISM) methodology that is based on multi-criteria decision-making approach. The MICMAC (Matrix of Cross-Impact Multiplications Applied to Classification) analysis is carried out for identifying the factors having high influential power. The research result indicated that ‘leadership’ and ‘organisational culture’ are the most significant critical success factors having highest driving power. These factors are deemed to be most effective for adopting KM strategies in the KSA public sector organisations. The chapter concludes that the leadership plays a key role in implementing KM strategies in the KSA. Leadership is about preparing organisation with a KM vision and values. The findings of this research provide valuable insight and guidance which will help the public sector decision makers to accomplish KM strategies effectively.
    • Social touch alters newborn monkey behavior

      Simpson, Elizabeth A; Maylott, Sarah E; Lazo, Roberto J; Leonard, Kyla A; Kaburu, Stefano; Suomi, Stephen J; Paukner, Annika; Ferrari, Pier F (Elsevier, 2019-12-31)
      In humans, infants respond positively to slow, gentle stroking—processed by C-tactile (CT) nerve fibers—by showing reductions in stress and increases in eye contact, smiling, and positive vocalizations. More frequent maternal touch is linked to greater activity and connectivity strength in social brain regions, and increases children’s attention to and learning of faces. It has been theorized that touch may prime children for social interactions and set them on a path towards healthy social cognitive development. However, less is known about the effects of touch on young infants’ psychological development, especially in the newborn period, a highly sensitive period of transition with rapid growth in sensory and social processing. It remains untested whether newborns can distinguish CT-targeted touch from other types of touch, or whether there are benefits of touch for newborns’ social, emotional, or cognitive development. In the present study, we experimentally investigated the acute effects of touch in newborn monkeys, a common model for human social development. Rhesus macaques (Macaca mulatta), like humans, are highly social, have complex mother-infant interactions with frequent body contact for the first weeks of life, making them an excellent model of infant sociality. Infant monkeys in the present study were reared in a neonatal nursery, enabling control over their early environment, including all caregiver interactions. One-week-old macaque infants (N = 27) participated in three 5-minute counter-balanced caregiver interactions, all with mutual gaze: stroking head and shoulders (CT-targeted touch), stroking palms of hands and soles of feet (Non-CT touch), or no stroking (No-touch). Immediately following the interaction, infants watched social and nonsocial videos and picture arrays including faces and objects, while we tracked their visual attention with remote eye tracking. We found that, during the caregiver interactions, infants behaved differently while being touched compared to the no-touch condition, irrespective of the body part touched. Most notably, in both touch conditions, infants exhibited fewer stress-related behaviors—self-scratching, locomotion, and contact time with a comfort object—compared to when they were not touched. Following CTtargeted touch, infants were faster to orient to the picture arrays compared to the other interaction conditions, suggesting CT-targeted touch may activate or prime infants’ attentional orienting system. In the No-touch condition infants attended longer to the nonsocial compared to the social video, possibly reflecting a baseline preference for nonsocial stimuli. In contrast, in both touch conditions, infants’ looked equally to the social and nonsocial videos, suggesting that touch may influence the types of visual stimuli that hold infants’ attention. Collectively, our results reveal that newborn macaques responded positively to touch, and touch appeared to influence some aspects of their subsequent attention, although we found limited evidence that these effects are mediated by CT fibers. These findings suggest that newborn touch may broadly support infants’ psychological development, and may have early evolutionary roots, shared across primates. This study illustrates the unique insight offered by nonhuman primates for exploring early infant social touch, revealing that touch may positively affect emotional and attentional development as early as the newborn period.
    • Non-Interactive Zero Knowledge Proofs for the Authentication of IoT Devices in Reduced Connectivity Environments

      Epiphaniou, Gregory; Walshe, Marcus; Al-Khateeb, Haider; Hammoudeh, Mohammad; Katos, Vasilios; Dehghantanha, Ali (Elsevier, 2019-12-31)
      Current authentication protocols seek to establish authenticated sessions over insecure channels while maintaining a small footprint considering the energy consumption and computational overheads. Traditional authentication schemes must store a form of authentication data on the devices, putting this data at risk. Approaches based on purely public/private key infrastructure come with additional computation and maintenance costs. This work proposes a novel noninteractive zero knowledge (NIZKP) authentication protocol that incorporates the limiting factors in IoT communication devices and sensors. Our protocol considers the inherent network instability and replaces the ZKP NP-hard problem using the Merkle tree structure for the creation of the authentication challenge. A series of simulations evaluate the performance of NIZKP against traditional ZKP approaches based on graph isomorphism. A set of performance metrics has been used, namely the channel rounds for client authentication, effects of the authentication processes, and the protocol interactions to determine areas of improvements. The simulation results indicate empirical evidence for the suitability of our NIKP approach for authentication purposes in resourceconstrained IoT environments.
    • Encapsulation of 2-amino-2-methyl-1-propanol with tetraethyl orthosilicate for CO2 capture

      Rama, Sidra; Zhang, Yan; Tchuenbou-Magaia, Fideline; Ding, Yulong; Li, Yongliang (Springer, 2019-12-31)
      Carbon capture is widely recognised as an essential strategy to meet global goals for climate protection. Although various CO2 capture technologies including absorption, adsorption and membrane exist, they are not yet mature for post-combustion power plants mainly due to high energy penalty. Hence researchers are concentrating on developing non-aqueous solvents like ionic liquids, CO2-binding organic liquids, nanoparticle hybrid materials and microencapsulated sorbents to minimize the energy consumption for carbon capture. This research aims to develop a novel and efficient approach by encapsulating sorbents to capture CO2 in a cold environment. The conventional emulsion technique was selected for the microcapsule formulation by using 2-amino-2-methyl-1-propanol (AMP) as the core sorbent and silicon dioxide (SiO2) as the shell. This paper reports the findings on the formulated microcapsules including key formulation parameters, microstructure, size distribution and thermal cycling stability. Furthermore, the effects of microcapsule quality and absorption temperature on the CO2 loading capacity of the microcapsules were investigated using a self-developed pressure decay method. The preliminary results have shown that the AMP microcapsules are promising to replace conventional sorbents.
    • An automatic method to identify citations to journals in news stories: A case study of UK newspapers citing Web of Science journals

      Kousha, Kayvan; Thelwall, Mike (The Chinese Academy of Sciences, 2019-12-31)
      Purpose: Communicating scientific results to the public is essential to inspire future researchers and ensure that discoveries are exploited. News stories about research are a key communication pathway for this and have been manually monitored to assess the extent of press coverage of scholarship. Design / methodology /Approach: To make larger scale studies practical, this paper introduces an automatic method to extract citations from newspaper stories to large sets of academic journals. Curated ProQuest queries were used to search for citations to 9,639 Science and 3,412 Social Science Web of Science (WoS) journals from eight UK daily newspapers during 2006-2015. False matches were automatically filtered out by a new program, with 94% of the remaining stories meaningfully citing research. Findings: Most Science (95%) and Social Science (94%) journals were never cited by these newspapers. Half of the cited Science journals covered medical or health-related topics, whereas 43% of the Social Sciences journals were related to psychiatry or psychology. From the citing news stories, 60% described research extensively and 53% used multiple sources, but few commented on research quality. Research Limitations: The method has only been tested in English and from the ProQuest Newspapers database. Practical implications: Others can use the new method to systematically harvest press coverage of research. Originality /value: An automatic method was introduced and tested to extract citations from newspaper stories to large sets of academic journals.
    • Issues and challenges of smart cities governance: a systematic review

      Keshvardoost, Sina; Renukappa, Suresh; Suresh, Subashini; Al-Janabi, Razan (CIB, 2019-12-31)
      Smart governance is a key factor when considering the successful implementation of smart cities strategies. Smart cities create an extensive variety of issues and challenges that often poorly organised to deal with by their respective governments as they grow in size and complexity. Therefore, developed countries are creating their infrastructure on the basis of smart governance and sustainable development to improve the quality of life for more than a decade now. This paper explores through a systematic review of the key challenges and issues that governance of smart cities is facing on this network performance by focusing on the governance models, with a particular interest on how these can contribute to successful smart city network governance. However, the government departments seem not to engage the public in every activity they do. Sometimes due to security and political reasons they try to maintain a distance from the public; this shows the issues within the existing smart cities governance model. This paper concludes that although there are considerable smart city dossiers in literature, their governance model and structural variations development across regions is lacking.
    • A novel real-time, lightweight chaotic-encryption scheme to enable next-generation audio-visual hearing-aids

      Adeel, Ahsan; Ahmad, Jawad; Larijani, Hadi; Hussain, Amir (Springer Nature, 2019-12-31)
      Objective: Next-generation audiovisual (AV) hearing-aids stand as a major enabler to realise more intelligible audio. However, high data rate, low latency, low computational complexity, and privacy are some of the major bottlenecks to the successful deployment of such advanced hearing-aids. To address these challenges, we propose a novel framework based on an integration of 5G Cloud-Radio Access Network (C-RAN), Internet of Things (IoT), and strong privacy algorithms to fully benefit from the possibilities these technologies have to offer. Background: Existing audio-only hearing-aids are known to perform poorly in noisy situations where overwhelming noise is present. Current devices make the signal more audible but remains deficient to restore intelligibility. Thus, we need hearing aids that can selectively amplify the attended talker or filter out acoustic clutter Methods: 1 The proposed 5G IoT enabled AV hearing-aid framework transmits the encrypted compressed AV information and receives encrypted enhanced reconstructed speech in real-time to address cybersecurity attacks such as location privacy and eavesdropping. For security implementation, a real-time lightweight AV encryption is proposed, based on a piece-wise linear chaotic map (PWLSM), Chebyshev map, and a secure hash and S-Box algorithm. For speech enhancement, the received secure AV (including lip-reading) information in the cloud is used to filter noisy audio using both deep learning and analytical acoustic modelling. To offload the computational complexity and real-time optimization issues, the framework runs deep learning and big data optimization processes in the background on the cloud. Results: The effectiveness and security of our proposed 5G-IoT-enabled AV hearing-aid framework are extensively evaluated using widely known security metrics. Our newly reported, deep learning-driven lip-reading approach for speech enhancement is evaluated under four different dynamic real-world scenarios (cafe, street, public transport, pedestrian area) using benchmark Grid and ChiME3 corpora. Comparative critical analysis in terms of both speech enhancement and AV encryption demonstrate the potential of our envisioned technology to deliver high quality speech reconstruction and secure mobile AV hearing aid communication. Conclusion: We believe that the proposed 5G IoT enabled AV hearing aid is an effective and feasible solution and represents a step change in the development of next generation multimodal digital hearing aids. The ongoing and future work includes more extensive evaluation and comparison with benchmark lightweight encryption algorithms and hardware prototype implementation.
    • Systematic literature research of the current implementation of Unmanned Aerial System (UAS) in the construction industry

      Vanderhorst, Hamlet Reynoso; Suresh, Subashini; Renukappa, Suresh (Blue Eyes Intelligence Engineering & Sciences, 2019-10-10)
      The implementation of UAS is bringing easiness and time saving activities into the currently construction site task. In the construction industry, diverse and relevant benefits of the technology have been identified through the project life cycle, such as monitoring project progress report, faster and low-cost land measurements and 3D modelling. Currently, the most valuable benefits of the UAS in the construction industry are related to automation the construction process, low cost, greater speed and safer real-time data collection compare with the traditional methods, and a reliable replacement over satellites and manned vehicles in terms of high-resolution images. However, there is a lack of exemplification and clarity of the actual implementation of the UAS in the construction industry in terms of adoption process and impacted usage. Therefore, a systematic literature review was carried out in order to explore the literature available of the topic related to implementation of unmanned aerial system in the construction industry, the most relevant tasks, cases, areas of usage and the reasons of applying it. The finding of this paper is providing exemplification models of current usage such as visualisation and disaster management, evolution map of the UAS according to the publication numbers and construction project stages when to use the UAS.
    • A hybrid RANS model of wing-body junction flow

      Rona, Aldo; El-Dosoky, M. F. F.; Adebayo, David (Elsevier, 2019-09-26)
      The three-dimensional flow separation over the Rood wing-body junction is an exemplar application of separation affecting many important flows in turbomachinery and aerodynamics. Conventional Reynolds Averaged Navier Stokes (RANS) methods struggle to reproduce the complexity of this flow. In this paper, an unconventional use is made of a hybrid Reynolds Averaged Navier Stokes (RANS) model to tackle this challenge. The hybridization technique combines the Menter 𝑘 − 𝜔 − 𝑆𝑆𝑇 model with the one equation sub-grid-scale (SGS) model by Yoshizawa through a blending function, based on the wall-normal distance. The hybrid RANS turbulence closure captured most of the flow features reported in past experiments with reasonable accuracy. The model captured also the small secondary vortex at the corner ahead of the wing nose and at the trailing edge. This feature is scarcely documented in the literature. The study highlights the importance of the spatial resolution near the wing leading edge, where this localised secondary recirculation was observed by the hybrid RANS model. It also provides evidence on the applicability of the hybrid Menter and Yoshizawa turbulence closure to the wing-body junction flows in aircraft and turbomachines, where the flows are characterised by a substantially time-invariant three-dimensional separation.
    • In vitro evaluation of the inhibitory effect of topical ophthalmic agents on acanthamoeba viability

      Heaselgrave, Wayne; Hamad, Anas; Coles, Steven; Hau, Scott (ARVO Journals, 2019-09-25)
      Purpose: To compare the antimicrobial effect of topical anesthetics, antivirals, antibiotics, and biocides on the viability of Acanthamoeba cysts and trophozoites in vitro. Methods: Amoebicidal and cysticidal assays were performed against both trophozoites and cysts of Acanthamoeba castellanii (ATCC 50370) and Acanthamoeba polyphaga (ATCC 30461). Test agents included topical ophthalmic preparations of common anesthetics, antivirals, antibiotics, and biocides. Organisms were exposed to serial two-fold dilutions of the test compounds in the wells of a microtiter plate to examine the effect on Acanthamoeba spp. In addition, the toxicity of each of the test compounds was determined against a mammalian cell line. Results: Proxymetacaine, oxybuprocaine, and especially tetracaine were all toxic to the trophozoites and cysts of Acanthamoeba spp., but lidocaine was well tolerated. The presence of the benzalkonium chloride (BAC) preservative in levofloxacin caused a high level of toxicity to trophozoites and cysts. With the diamidines, the presence of BAC in the propamidine drops was responsible for the activity against Acanthamoeba spp. Hexamidine drops without BAC showed good activity against trophozoites, and the biguanides polyhexamethylene biguanide, chlorhexidine, alexidine, and octenidine all showed excellent activity against trophozoites and cysts of both species. Conclusions: The antiamoebic effects of BAC, povidone iodine, and tetracaine are superior to the current diamidines and slightly inferior to the biguanides used in the treatment for Acanthamoeba keratitis. Translational Relevance: Ophthalmologists should be aware that certain topical anesthetics and ophthalmic preparations containing BAC prior to specimen sampling may affect the viability of Acanthamoeba spp. in vivo, resulting in false-negative results in diagnostic tests.
    • Drug induced dermatological reaction of the 100 most commonly prescribed medications in UK hospitals

      AL-ABADIE, MOHAMMED; OUMEISH, FARIS; AL-RUBAYE, MOHAMMED; AL-ABADIE, DINA; BALL, PATRICK ANTHONY; Morrissey, Hana (Innovare Academic Sciences Pvt Ltd, 2019-09-16)
      Objective: It is commonly reported that medicines have side effects related to dermatological practice. However, it is extremely difficult to establish how commonly, or rarely skin-related medication side effects occur. Common dermatological side effects include rash, pruritus, and photosensitivity. Objective: To demonstrate the dermatological side-effects of the most commonly prescribed medications in the United Kingdom. Methods: This paper discusses dermatological side-effects of the commonly prescribed medications, including uncommon or rare manifestations such as angioedema and Stevens - Johnson syndrome (SJS). The list used for the most frequently prescribed drugs in the United Kingdom was created by nurses. This list was compared to the British National Formulary to demonstrate the reported frequency of occurrence of dermatological side-effects or complications. Conclusion: The top 100 prescribed medication cause a number of dermatological side effects that need to be considered when they are prescribed to patients who have pre-existing skin conditions. Additionally, when confronted with a common dermatological problem in any patient, clinicians should always consider the possibility of a drug adverse reaction.

Expanding knowledge within this area could assist millions of affected people to seek help.</jats:p>
    • Adsorptive Removal of Iron and Manganese from Groundwater Samples in Ghana by Zeolite Y Synthesized from Bauxite and Kaolin

      Williams, Craig; Kwakye-Awuah, Bright; Sefa-Ntiri, Baah; Von-Kiti, Elizabeth; Nkrumah, Isaac (MDPI, 2019-09-13)
      Ground water samples from residential homes in three Regions of Ghana: Central, Greater Accra and Ashanti, were analyzed for iron and manganese contamination. The samples were exposed to characterized zeolite Y by X-ray diffraction, scanning electron microscopy, energy dispersive x-ray spectroscopy, Fourier transformed-infrared spectroscopy and thermos gravimetric-differential thermal analysis. Zeolite Y is able to remove 98% of iron and 97% of manganese within an hour. The adsorption of both iron and manganese follows the Freundlich model, whilst the kinetic studies show that pseudo-first order and intra particle and film diffusion models provided the best fit, suggesting the transport of the ions onto the zeolite Y surface and the subsequent diffusion into the zeolite Y framework. The adsorption at 0.2 mg L−1 Fe (𝑄0.2) is calculated to be 0.023 mg g−1 for the Freundlich adsorption model, whilst that of manganese at 0.05 mg L−1 Mn (𝑄0.05) is evaluated to be 0.015 mg g−1. The zeolite retains its adsorption properties when retrieved from the first exposure water sample, washed copiously with distilled water and added to fresh water samples. The results suggest that zeolite Y can be used as a potential adsorbent for the removal of iron and manganese from groundwater.
    • Secukinumab efficacy and safety: Reporting on the experiences of clinicians and patients

      Al Abadie, Mohammed; Ayaz, Ambreen; Adcock, Lyn; Elston, Georgina; Beswick, Samantha; Cartwright, Peter; Ibrahim, Rangeen; Ball, Patrick; Morrissey, Hana (Research Trends, 2019-09-07)
      Secukinumab (SEC) is a human monoclonal antibody that selectively neutralizes IL-17A, a key cytokine involved in the development of psoriasis. Superior efficacy has been demonstrated in clinical trials with up to 79% of moderate-to-severe psoriasis patients achieving a PASI 90 at week 16 and 75% achieving a PASI 90 at week 52. However, the population recruited into clinical trials are different to the real-world population. The aim of this paper is to discuss the safety and efficacy of SEC based on ‘real-world data’ when used in patients with multiple co-morbidities and concomitant medications. Two clinical audits conducted were based on a clinical audit checklist, which was adopted and included in all patients’ usual care as the patient-management model for biological therapies. Patients on SEC were identified from our pharmacy database and data was collected from electronic patient records between September 2015 and May 2018. The psoriasis area severity index (PASI) and dermatology life quality index (DLQI) were extracted at baseline and at 16 weeks. The results from the rheumatology departments of the two hospitals were then compared. A total of 135 patients’ data was analysed. SEC was found to offer an efficacious real-world treatment option with response rates generally higher than observed in pivotal Phase III clinical trials. Response rates were higher in biologic naïve patients than non-naïve patients. There were no unusual safety signals; however, long-term efficacy and sustainability are yet to be established.
    • Sunlight exposure and serum vitamin D status among community dwelling healthy women in Sri Lanka

      Morrissey, Hana; Subasinghe, Sewwandi; Ball, PATRICK A; Lekamwasam, Sarath; Waidyaratne, Eisha (European Journal of Pharmaceutical and Medical Research, 2019-09-02)
      Introduction: Hypovitaminosis D is prevalent and linked with a multitude of co-morbidities. The high prevalence of hypovitaminosis D, despite the availability of sunlight throughout the year has raised many questions. Objective: This study aimed to assess the prevalence of vitamin D deficiency and its associations with diet and sunlight in premenopausal women in Sri Lanka. Methods: Community dwelling healthy women between 20-40 years (n = 132) were selected. Consumption of vitamin D (vit-D) rich dairy and non-dairy foods were estimated. Serum vit-D and calcium were measured. Vit-D reference values introduced by Lips et al were used to categorize subjects. Results and conclusion: Eight subjects (6.1%) were Vit-D deficient while 68 (51.5%) had Vit-D insufficiency. No difference in vit-D status according to age (20-30 vs 31-40 years). Vit-D was higher in women who had sun exposure >2 hours/day compared to women with <2 hours sunlight. Vit-D positively associated with dairy (Pearson r = 0.20, p = 0.023) and non-dairy vit-D rich food intake (Pearson r = 0.21, p = 0.014). Hypovitaminosis D is prevalent among community dwelling healthy middle-aged women in Sri Lanka. Higher vit-D level is associated with sufficient duration of sun exposure and dairy, non-dairy food intake.
    • Smart solutions in the oil and gas industry: A review

      Sarrakh, Redouane; Suresh, Renukappa; Suresh, Subashini; Al Nabt, Saeed (IACSIT Press, 2019-09-01)
      A great importance had been given to sustainable development in the past decades, especially within the oil and gas industry, companies around the world are expanding their strategies in order to follow the current trend and information and Communication Technology are considered as a key factor for achieving sustainable development. That along with the constant technological development the oil and gas sector is experiencing had forced the industry to adapt smart solutions in order to meet the market’s changing demand and improve the efficiency of its operations. With the goal of studying examples of smart solutions within the oil and gas industry from a general perspective, a literature review was conducted and the main characteristics and attributes of each solution had been exploited. Smart solutions gained a great appreciation in the industry, but their application is still modest, and the industry did not benefit from it in a meaningful way and has little impact on companies’ business model.
    • A new algorithm for zero-modified models applied to citation counts

      Shahmandi Hounejani, Marzieh; Wilson, Paul; Thelwall, Michael (International Society for Scientometrics and Informetrics, 2019-08-31)
      Finding statistical models for citation count data is important for those seeking to understand the citing process or when using regression to identify factors that associate with citation rates. As sets of citation counts often include more or less zeros (uncited articles) than would be expected under the base distribution, it is essential to deal appropriately with them. This article proposes a new algorithm to fit zero-modified versions of discretised log-normal, hooked power-law and Weibull models to citation count data from 23 different Scopus categories from 2012. The new algorithm allows the standard errors of all parameter estimates to be calculated, and hence also confidence intervals and p-values. This algorithm can also estimate negative zero-modification parameters corresponding to zero-deflation (fewer uncited articles than expected). The results find no universal best model for the 23 categories and a given dataset may be zero-inflated relative to one model, but zero-deflated relative to another
