Authors: Matthew Ugochukwu O.
Published: November 2019

This paper looked at multimedia application techniques in an e-learning environment in the digital libraries in Nigeria as an alternative paradigm to information management. The article surveyed the current state of affairs in the Nigeria Educational sector through careful review of the budget allocation to the Ministry of Education and discovered a negative trend. The article proposes an alternative paradigm to the current method of information access and distribution in the Nigeria Libraries to accommodate e-learning functionalities. The article attempted to define the term data mining in relation to its usage in driving restructuring in line with the Nigerian government agenda for national development. It also covers different data mining features and standards as its main focus was to engage students and learnable groups productively. The article explains why it is necessary to implement a multimedia Internet of Things in the Eastern Nigeria Institutions, basically libraries with the help of internet repositories with the vision of expanding its functionalities to accommodate other five geopolitical regions of the country. The choice of Eastern Nigeria is on the merit of economic stability, relative peace, and general orientation to Western civilization and culture. The design will be centrally built as knowledge repository otherwise referred as Knowledge Powerhouse that will service other subregions through a wireless data sharing architecture. The study also revealed the budget implication and established to what extend the multimedia Internet of things will be used to drive key innovations in the institution Libraries for human capital development in Nigeria and by extension the entire continent of Africa.

Authors: Al Qasem Osama , Akour Mohammed
Published: November 2019

Software faults prediction (SFP) processes can be used for detecting faulty constructs at early stages of the development lifecycle, in addition to its being used in several phases of the development process. Machine learning (ML) is widely used in this area. One of the most promising subsets from ML is deep learning that achieves remarkable performance in various areas. Two deep learning algorithms are used in this paper, the Multi-layer perceptrons (MLPs) and Convolutional Neural Network (CNN). In order to evaluate the studied algorithms, four commonly used datasets from NASA are used i.e. (PC1, KC1, KC2 and CM1). The experiment results show how the CNN algorithm achieves prediction superiority of the MLP algorithm. The accuracy and detection rate measurements when using CNN has reached the standard ratio respectively as follows: PC1 97.7% - 73.9%, KC1 100% - 100%, KC2 99.3% - 99.2% and CM1 97.3% - 82.3%. This study provides promising results in using the deep learning for software fault prediction research.

Published: November 2019

“Serious games” refer to games that go beyond pure entertainment and promote learning. They are utilized within a variety of learning environments enabling students to acquire knowledge and skills, while they offer wide benefits. The authors' team measured and analyzed various factors related to the gameplay and educational content when 2D and 3D serious games are introduced in the educational process. The main objective focused on the correlation of the University students' views that were sharing common characteristics, like gender, information and communication technology skills, game playing experience, and specific scientific background with factors that related to the gameplay as well as the learning effectiveness. The results revealed that game-playing experience had a more positive impact in the case of males, while perceived learning effectiveness of 2D was higher compared to the 3D serious game for both genders. Moreover, there are differentiations among females concerning the scientific background, Information and Communication Technology skills and game-playing experience.
Copy-Move Forgery Detection Based on Automatic Threshold Estimation
Authors: Hegazi Aya , Taha Ahmed , Selim Mazen Mohamed
Published: November 2019

Recently, users and news followers across websites face many fabricated images. Moreover, it goes far beyond that to the point of defaming or imprisoning a person. Hence, image authentication has become a significant issue. One of the most common tampering techniques is copy-move. Keypoint-based methods are considered as an effective method for detecting copy-move forgeries. In such methods, the feature extraction process is followed by applying a clustering technique to group spatially close keypoints. Most clustering techniques highly depend on the existence of a specific threshold to terminate the clustering. Determination of the most suitable threshold requires a huge amount of experiments. In this article, a copy-move forgery detection method is proposed. The proposed method is based on automatic estimation of the clustering threshold. The cutoff threshold of hierarchical clustering is estimated automatically based on clustering evaluation measures. Experimental results tested on various datasets show that the proposed method outperforms other relevant state-of-the-art methods.

Published: November 2019

This article addresses the challenges faced by the telecommunication industry in Brunei Darussalam posed by the evolution of smartphones and the rapid growth of the Internet over the years, particularly, the changes in general user usage pattern, as well as examining the measures undertaken by these companies to address these challenges. Online questionnaires were distributed to the general public for the purpose of collecting the pattern of phone usage both presently and a decade ago. The findings indicated that there was a shift in the overall user preference of communicating via mobile phones, where, in this day and age, most prefer to communicate through the internet as opposed to a decade ago where consumers were more partial to communicating via traditional SMS and calls. This shift resulted in high demand for mobile internet data by the consumers, hence, creating a huge hindrance towards the revenue streams of the telecommunication companies. This pressure called for a restructuring in the telecommunication companies to accommodate this growing trend of high Internet usage.

Published: November 2019

The extensive development of electronic gadgets along with technology-oriented communication tools has created a significant impact on the realm of online retail banking transactions. In Bangladesh, online retail banking can strengthen the financial frameworks by establishing associations between both financial institutions and customers. The evaluation of e-service quality, trust, and customer's adoption of advanced technology are still unexplored within the retail banking context. Thus, this research paper fills a specific research gap via empirically testing the role of trust in between the relationship of e-service quality and customers' patronage intentions in the context of online retail banking. Moreover, the research also examines the moderation role of adoption of advanced technology in between the relationship among trust and customers' patronage intentions. Structural equation modelling (SEM) was applied to analyze the proposed hypotheses. The results confirmed that customer's trust plays a significant role in mediating the relationship between e-service quality and customers' patronage intentions. Adoption of advanced technology has also proved as significant moderator in explaining trust and customer's patronage intention in online retail banking setting.
Speed of Use of Social Media as an Antecedent of Speed of Business Internationalization
Authors: Rialp-Criado Josep , Alarcón-del-Amo María-del-Carmen , Rialp Alex
Published: November 2019

Despite various advances in international business and entrepreneurship literatures and increasing interest in speed of internationalization mainly among international entrepreneurship scholars, the relationship between the use of social media and the internationalization speed of the firm remains poorly investigated. This article presents the reflective construct “speed of use of social media” and proves its positive effect on the third order formative construct “speed of internationalization.” Furthermore, using multi-group analysis, the article demonstrates that this effect is moderated by the industry where the company performs (business-to-customer vs. business-to-business) and its export intensity, but not by the size of the firm. The results obtained open an interesting area for further research in the role of Web 2.0 and social networking in future knowledge management systems of international new ventures companies.
Galectin-9 Expression Defines a Subpopulation of NK Cells with Impaired Cytotoxic Effector Molecules but Enhanced IFN-γ Production, Dichotomous to TIGIT, in HIV-1 Infection

Published: November 2019

NK cell functions are tightly regulated by the balance between the inhibitory and stimulatory surface receptors. We investigated the surface expression of galectin-9 (Gal-9) and its function in NK cells from HIV-infected individuals on antiretroviral therapy, long-term nonprogressors, and progressors compared with healthy controls. We also measured the expression of TIGIT and TIM-3 on different NK cell subpopulations and compared their functionality to Gal-9+ NK cells. Our data demonstrated significant upregulation of Gal-9 on NK cells in HIV-infected groups versus healthy controls. Gal-9 expression was associated with impaired expression of cytotoxic effector molecules granzyme B, perforin, and granulysin. In contrast, Gal-9 expression significantly enhanced IFN-γ expression in NK cells of HIV-1–infected individuals. We also found an expansion of TIGIT+ NK cells in HIV-infected individuals; however, dichotomous to Gal-9+ NK cells, TIGIT+ NK cells expressed significantly higher amounts of cytotoxic molecules but lower IFN-γ. Moreover, lower expression of cytotoxic effector molecules in Gal-9+ NK cells was associated with higher CD107a expression, which suggests indiscriminate degranulation. Importantly, a positive correlation between the plasma viral load and Gal-9+ NK cells was observed in progressors. Finally, we found that a cytokine mixture (IL-12, IL-15, and IL-18) can improve effector functions of Gal-9+ NK cells in HIV-infected individuals, although, such an effect was observed for Gal-9− NK cells, as well. Overall, our data highlight the important role of Gal-9 in dysfunctional NK cells and, more importantly, a dichotomy for the role of Gal-9 versus TIGIT and suggest a potential new avenue for the development of therapeutic approaches.
Cross-Reactivity to Kynureninase Tolerizes B Cells That Express the HIV-1 Broadly Neutralizing Antibody 2F5

Published: November 2019

2F5 is an HIV-1 broadly neutralizing Ab that also binds the autoantigens kynureninase (KYNU) and anionic lipids. Generation of 2F5-like Abs is proscribed by immune tolerance, but it is unclear which autospecificity is responsible. We sampled the BCR repertoire of 2F5 knock-in mice before and after the first and second tolerance checkpoints. Nearly all small pre–B (precheckpoint) and 35–70% of anergic peripheral B cells (postcheckpoint) expressed the 2F5 BCR and maintained KYNU, lipid, and HIV-1 gp41 reactivity. In contrast, all postcheckpoint mature follicular (MF) B cells had undergone L chain editing that purged KYNU and gp41 binding but left lipid reactivity largely intact. We conclude that specificity for KYNU is the primary driver of tolerization of 2F5-expressing B cells. The MF and anergic B cell populations favored distinct collections of editor L chains; surprisingly, however, MF and anergic B cells also frequently expressed identical BCRs. These results imply that BCR autoreactivity is the primary determinant of whether a developing B cell enters the MF or anergic compartments, with a secondary role for stochastic factors that slightly mix the two pools. Our study provides mechanistic insights into how immunological tolerance impairs humoral responses to HIV-1 and supports activation of anergic B cells as a potential method for HIV-1 vaccination.
Macrophages Are a Potent Source of Streptococcus-Induced IFN-β
Authors: Feuerstein Reinhild , Gres Vitka , Elias Perdigó Núria , Baasch Sebastian , Freudenhammer Mirjam , Elling Roland , Henneke Philipp
Published: November 2019

IFN-β essentially modulates the host response against mucocutaneous colonizers and potential pathogens, such as group B Streptococcus (GBS). It has been reported that the dominant signaling cascade driving IFN-β in macrophages (MΦ) in streptococcal infection is the cGAS–STING pathway, whereas conventional dendritic cells (DC) exploit endosomal recognition by intracellular TLRs. In this study, we revisited this issue by precisely monitoring the phenotypic dynamics in mixed mouse MΦ/DC cultures with GM-CSF, which requires snapshot definition of cellular identities. We identified four mononuclear phagocyte populations, of which two were transcriptionally and morphologically distinct MΦ–DC-like subsets, and two were transitional types. Notably, GBS induced a TLR7-dependent IFN-β signal only in MΦ-like but not in DC-like cells. IFN-β induction did not require live bacteria (i.e., the formation of cytolytic toxins), which are essential for IFN-β induction via cGAS–STING. In contrast to IFN-β, GBS induced TNF-α independently of TLR7. Subsequent to the interaction with streptococci, MΦ changed their immunophenotype and gained some typical DC markers and DC-like morphology. In summary, we identify IFN-β formation as part of the antistreptococcal repertoire of GM-CSF differentiated MΦ in vitro and in vivo and delineate their plasticity.
IFN-Stimulated Genes in Zebrafish and Humans Define an Ancient Arsenal of Antiviral Immunity
Authors: Levraud Jean-Pierre , Jouneau Luc , Briolat Valérie , Laghi Valerio , Boudinot Pierre
Published: November 2019

The evolution of the IFN system, the major innate antiviral mechanism of vertebrates, remains poorly understood. According to the detection of type I IFN genes in cartilaginous fish genomes, the system appeared 500 My ago. However, the IFN system integrates many other components, most of which are encoded by IFN-stimulated genes (ISGs). To shed light on its evolution, we have used deep RNA sequencing to generate a comprehensive list of ISGs of zebrafish, taking advantage of the high-quality genome annotation in this species. We analyzed larvae after inoculation of recombinant zebrafish type I IFN, or infection with chikungunya virus, a potent IFN inducer. We identified more than 400 zebrafish ISGs, defined as being either directly induced by IFN or induced by the virus in an IFNR-dependent manner. Their human orthologs were highly enriched in ISGs, particularly for highly inducible genes. We identified 72 orthology groups containing ISGs in both zebrafish and humans, revealing a core ancestral ISG repertoire that includes most of the known signaling components of the IFN system. Many downstream effectors were also already present 450 My ago in the common ancestor of tetrapods and bony fish and diversified as multigene families independently in the two lineages. A large proportion of the ISG repertoire is lineage specific; around 40% of protein-coding zebrafish ISGs had no human ortholog. We identified 14 fish-specific gene families containing multiple ISGs, including finTRIMs. This work illuminates the evolution of the IFN system and provides a rich resource to explore new antiviral mechanisms.

'Awareness' in metamorphosing pupae (Lepidoptera: Pieridae)
Authors: Hawes Timothy C.
Published: November 2019

Neurobiological studies of model insect species have established that the nervous system retains some larval innervations, remodels others, and develops other new adult innervations during metamorphosis. Using a simple behavioral response – the ability to ‘kick’ by pupae of the pierid, Catopsilia pomona (Fabricius, 1775) - it was possible to assay for the retention of environmental awareness during ontogenetic reorganization. All pupae kicked 24h after ecdysis, 48% of pupae kicked at the pharate adult stage, and 28% of pupae kicked every day of their development (6.52 d ± 0.10). Both the mode and temporal expression of the response indicate that this retained awareness has larval origins. Variability in the response supports the inference that this response is mediated, to some extent, by prior experience rather than purely ‘reflex’. This is consistent with a Darwinian explanation of the behavior (and retained environmental awareness itself) as serving a protective function in pupae.
Araneae.it: the online Catalog of Italian spiders, with addenda on other Arachnid Orders occurring in Italy (Arachnida: Araneae, Opiliones, Palpigradi, Pseudoscorpionida, Scorpiones, Solifugae)
Authors: Pantini Paolo , Isaia Marco
Published: November 2019

In this contribution we present the Catalog of Italian spiders, produced on the base of the available scientific information regarding spider species distribution in Italy. We analysed an amount of 1124 references, resulting in a list of 1670 species and subspecies, grouped in 434 genera and 53 families. Information on spider biodiversity in Italy has increased rapidly in the last years, going from 404 species at the end of XIX century, to 1400 in the 1990s, to the current 1670. However, the knowledge on the distribution of the Italian species is far from being complete and it seems likely that there are still new species to be found or described. The Italian spider fauna is characterized by the presence of a relevant number of endemic species (342). Concerning families, Linyphiidae show the highest number of species (477) and the highest number of endemics (114). Gnaphosidae (166) and Salticidae (144) follows in terms of species richness, while Dysderidae (72) and Agelenidae (38) follows as total number of endemics. Information regarding the regional distribution revealed great unbalance between Northern and Southern Italy, with very scarce records for some regions in the South. This work is accompanied by an online version freely available online at www.araneae.it, where all information is thoroughly detailed and regularly updated by the authors. Besides spiders, we also provide, the species lists of other Arachnid orders occurring in Italy (Opiliones, Palpigradi, Pseudoscorpionida, Scorpiones, Solifugae). The lists and the associated details are available in a dedicated section of the online version of the Catalog.

Spirituality and beliefs of Colombian internal conflict survivors
Authors: Villegas Diana L.
Published: November 2019

Remarkable stories of resilience and forgiveness have been reported in the wake of the internationally recognised peace process in Colombia. From the perspective of Christian spirituality, this study seeks to understand the individual and communal values, beliefs and practices that made the reconciliation and restoration of a community possible after severe dislocation and violence, some of it of neighbour against neighbour. Interviews conducted in the field (in San Carlos, Antioquia, Colombia) and transcribed by the author were used as texts. Transcripts were studied taking into account cultural, geographic and historical contexts. I found that a deeply rooted family- and community-based Catholic culture, brought by the Spanish in the 16th century and continuing to influence this rural area, offered values, beliefs and devotional practices that gave meaning, strength and empowered the ability to forgive. Also, psychological and pastoral tools for grieving, together with sociological and political values about reconciliation and the rebuilding of a community’s fabric, intertwined with the religious values to deepen the capacity for reconciliation and community rebuilding. The experiences of these interviewees reveal a form of Christian spirituality lived through family and community ties that was augmented and empowered by values and practices of non-religious institutions, making possible significant personal and communal journeys of transformation and the concomitant remarkable resilience.
Christus medicus – Christus patiens: Healing as exorcism in context
Authors: Van Aarde Andries G.
Published: November 2019

The aim of this article is to argue that healing stories in the Jesus tradition should be understood as exorcisms, even if the concept of demonisation does not occur in the narrative. In the theistic and mythological context of the 1st-century Graeco-Roman religious and political world, external forces responsible for social imbalances pertain to the demonisation of body and spirit. Medical cure was also embedded in the same biopolitical setting. The article describes aspects of this biopolitics and the role of ancient physicians. However, Jesus’ revolutionary acts were not deeds of a medical doctor, but ought to be understood as the healing activity of a faith healer who empowered traumatised people by creating safe space for them within a quasi-fictive kinship network. The article concludes with an application of the dialectic notion ‘Christus medicus – Christus patiens’ in the life of the present-day network of Jesus-followers.
Knowledge of final year medicine, pharmacy, audiology and nursing students in South Africa on drug-induced ototoxicity: A pilot study
Authors: Mogole Omphile , Schellack Natalie , Hollander Cara , Ramma Lebogang
Published: November 2019

Background: There is a high prevalence of human immunodeficiency virus (HIV), tuberculosis (TB), cancer and malaria in South Africa, and the drugs used to treat these conditions can be ototoxic. It is therefore important that healthcare professionals are able to identify and understand these drugs and their effects to ensure effective care of the patient.Objective: This study aimed to assess the knowledge regarding pharmacotherapy-induced ototoxicity amongst final year, medicine, pharmacy, audiology and nursing students across South African universities.Methods: A descriptive cross-sectional study design was used, and data were collected via a self-administered online questionnaire. Non-probability purposive sampling was used to identify the participants at the universities which train audiologists, pharmacists, medical and nursing students.Results: An overall response rate of 41% (n = 720) was obtained. Sixty-four per cent (n = 461) of respondents were women (median age: 23 years). The majority of the respondents (95%) knew what pharmacotherapy-induced ototoxicity was, but a few (39%) knew the general signs and symptoms of ototoxicity. Furthermore, just less than half of the sample (48%) could identify the specific ototoxic medicines and the type of damage caused by this medication.Conclusion: To manage pharmacotherapy-induced ototoxicity effectively, a multidisciplinary healthcare team must have sufficient knowledge about ototoxicity. Therefore, efforts should be made to introduce extensively concepts of pharmacotherapy-induced ototoxicity into the undergraduate curricula of pharmacy, medical, nursing and audiology programmes.

OT Practice Patterns in Rural States: Does the College Experience Influence Rural Employment Choice?
Authors: Hanson Debra , Jedlicka Janet , Klug Marilyn , Harris Nicole
Published: November 2019

Date Presented 04/06/19

A survey of 225 OT practitioners living in rural states explored practice patterns and influences on employment choice. Rural and urban practitioner differences were noted in variability of hours spent working, number of work locations, and time spent in fieldwork education. Rural practice choice was influenced by fieldwork participation but not loan debt. Findings support the value of rural exposure in the curriculum and customized rural fieldwork educator support.

Children's Subjective Well-Being: Transformative Interaction Between Child, Context, and Meaningful Activity
Authors: Brockevelt Barbara , Cerny Shana
Published: November 2019

Date Presented 04/06/19

Often, social indicators and caregiver perspective are used to define children’s well-being. This research, part of a multinational qualitative study, sought to understand how children ages 8 to 13 years conceptualize and experience their own well-being. Results revealed several indicators of well-being that fell into six domains: social connectedness, physical health, mastery and agency, safety and security, meaningful access to resources, and meaningful use of time through activity.

Published: November 2019

Date Presented 04/06/19

An individual may face many challenges to recovery after stroke, particularly with regaining use of their upper extremity. Although repetitive task-oriented training is considered an optimal intervention in stroke rehabilitation, there is limited research using this type of treatment in a virtual context. The purpose of the study was to provide two virtual-reality interventions over four weeks to adults who were poststroke and measure their change in function in their affected upper extremity.

Published: November 2019

Date Presented 04/06/19

There has been a lasting debate over whether sensory features are a core characteristic or comorbid phenomenon of ASD. This study explores whether sensory reactivity (hyper and hypo reactivity) may be a distinguishing characteristic of ASD. Understanding these phenotypic characteristics of ASD can help inform personalized OT intervention for sensory features as well as aid in early diagnosis.

Published: November 2019

Date Presented 04/06/19

Reports support the hypothesis that sensory issues may be related to atypical defecation habits in children. Practice in this area is limited by the lack of validated measures. We used Rasch analysis, directed content analysis, and expert review to validate the Toileting Habit Profile Questionnaire (THPQ). After adjusting items, we examined the construct validity of the revised version (THPQ-R). The THPQ-R appears to capture challenging defecation behaviors related to sensory over-reactivity.
