An integration model for identifying the determinants of the adoption and implementation level of HRIS applications and Its effectiveness in business organisations in Jordan
This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel UniversityThis thesis investigates the influence of firms’ internal and external environmental factors upon their adoption of HRIS behaviour (i.e., the variation between adopters and non-adopters) and the level of implementation of HRIS applications and its effectiveness. An integrated conceptual framework was developed for the factors that determine the organisation’s adoption and the level of practice of HRIS applications. This framework integrates ideas and elements from the Diffusion of innovation Theory (DOI) and technology organization environment (TOE) model, the Unified Theory of Acceptance and Use of Technology (UTAUT) and the IT studies in the area of HRM. Data were collected through structured-directed interviews with 236 respondents. The survey units were the shareholding companies in Jordan, and the key single respondents approach was employed. The findings of the study support that internal and external environmental factors are related not only to adoption of HRIS behaviour (i.e., the difference between adopters and non-adopters), but also to the level of implementing of HRIS applications. In comparison to each environmental dimension acting alone, the integration approach of the two internal and external dimensions gives better explanation not only of the prediction of the level of implementing of HRIS applications, but also of the prediction of adoption behaviour. Therefore, a better understanding of adoption of HRIS behaviour and the level of implementing of HRIS applications requires that firms’ environmental factors be viewed as whole (i.e., the interaction of the internal and external dimension) rather than being isolated fragments (i.e., only a single dimension). The current research contributes to the existing body of knowledge by enhancing current understanding of the organisational adoption of HRIS, which is an under-researched area in Jordan as a developing country. By employing analytical tools based on Rogers’s Innovation Diffusion Theory , UTAUT, TOE , and the findings of empirical studies of IT adoption, evidence confirms that the adoption of HRIS in the business organisations depends largely on interaction of internal and external environmental factors and the findings support the need for an integrated view of the adoption phenomenon. In that respect, this study also attempts to make an important theoretical contribution towards articulating differences in the determinants of adoption and the level of implementations of HRIS applications and its effectiveness

GARDNet: Robust Multi-View Network for Glaucoma Classification in Color Fundus Images
Glaucoma is one of the most severe eye diseases, characterized by rapid
progression and leading to irreversible blindness. It is often the case that
diagnostics is carried out when one's sight has already significantly degraded
due to the lack of noticeable symptoms at early stage of the disease. Regular
glaucoma screenings of the population shall improve early-stage detection,
however the desirable frequency of etymological checkups is often not feasible
due to the excessive load imposed by manual diagnostics on limited number of
specialists. Considering the basic methodology to detect glaucoma is to analyze
fundus images for the optic-disc-to-optic-cup ratio, Machine Learning
algorithms can offer sophisticated methods for image processing and
classification. In our work, we propose an advanced image pre-processing
technique combined with a multi-view network of deep classification models to
categorize glaucoma. Our Glaucoma Automated Retinal Detection Network (GARDNet)
has been successfully tested on Rotterdam EyePACS AIROGS dataset with an AUC of
0.92, and then additionally fine-tuned and tested on RIM-ONE DL dataset with an
AUC of 0.9308 outperforming the state-of-the-art of 0.9272. Our code is

Perception of Jaw Osteonecrosis among Medical Specialists Perception of Medication-related Osteonecrosis of the Jaws among Iraqi Medical Specialists
Objective Osteonecrosis of the jaws is the adverse effect of antiresorptive and antiangiogenic agents, which is termed as medication-related osteonecrosis of the jaws
(MRONJ). This complication, which is prominent and growing, is seen in the oral and
maxillofacial region. This cross-sectional survey aimed to evaluate MRONJ awareness
among Iraqi medical specialists.
Materials and Methods A questionnaire-based survey was performed on medical specialists practicing general surgery, urology, orthopedics, rheumatology, and oncology. The
questionnaire consisted of four questions regarding drug prescription, patients’ preparation before drug administration, in addition to awareness and knowledge about MRONJ.
Results Among 132 specialists, 57% did not prescribe such drugs. A significant difference existed among groups regarding dental referral, and MRONJ awareness and
knowledge. The highest rates were seen in the oncologist group.
Conclusions Improvement of MRONJ perception and knowledge among medical
specialists, besides implementation of dental referral, are essential in the prevention,
diagnosis and treatment of MRONJ
Across-sectional survey on medication-related osteonecrosis of the jaws' knowledge and awareness in a sample of dental society
Background
Medication-related osteonecrosis of the jaws (MRONJ) is a prominent complication and growing problem related to the oral and maxillofacial region due to antiresorptive and antiangiogenic agents. Awareness about MRONJ is crucial for all dental practitioners identify ‘at risk’ patients for appropriate advice and management. This cross-sectional survey aimed to appraise MRONJ awareness and knowledge among dentists.
Materials and methods
A questionnaire-based survey was carried out through one hundred and seventy eight dentist who recruited in three groups; the first group comprised 113 general dental practitioners (GDP), 33 dental radiologist (DR) included in the second, and 32 oral and maxillofacial surgeon (OMS) in the third group. MRONJ awareness was evaluated by asking all respondents a question of “Did you heard about MRONJ? In addition, the detailed knowledge on the subject in question were addressed through fourteen, nine, and three questions for OMSs, DRs, and GDPs respectively.
Results
A significant difference were existed among groups with a rate of MRONJ's awareness of 33.6%, 48.5%, and 84.4% for GDPs, DRs, and OMSs respectively. Concerning MRONJ knowledge, significantly highest rates seen in OMSs set with 48.55%. In contrast, the average scores of DRs were 30.64%, and the GDPs group recorded the least value with 16.67%.
Conclusions
Strengthen the MRONJ awareness and knowledge among general dentists and dental specialists are essential to identify ‘at risk’ patients for appropriate advice and management
Functional role of polysaccharide intercellular adhesin during Staphylococcus epidermidis biofilm interaction with the innate immune system.
Synthesis of polysaccharide intercellular adhesin (PIA), accumulation associated protein (Aap) and extracellular matrix binding protein (Embp) are major mechanisms used by Staphylococcus epidermidisto evade immunity through biofilm formation. These evasion strategies are particularly suited for colonisation of medical devices such as heart valves, joint prostheses and central venous catheters resulting in significant patient morbidity. Two biological activities of PIA, Aap and Embp contribute to their role as an evasion molecules. Firstly their ‘barrier’ function limiting penetration of immune cells and antibiotics. Secondly, their ‘immunomodulatory’ properties which influence cytokine responses. At present little is known about these functional activities in physiological media and biological fluids.This thesis uses a cell biology approach to study the environment necessary for PLA production. Specifically in vitromodelling of biofilm formation, PIA production and S. epidermidisleukocyte co-culture experiments have been used to assess conditions that are conducive for PIA production.This thesis has identified that:• Specific cell culture media cause unique profiles of biofilm accumulation with differential production of PIA, Aap and Embp.• Fetal bovine serum and pooled human serum support S. epidermidisgrowth but differentially affect biofilm formation by PIA, Aap and Embp.• Large scale production of PIA (~20mg) can be achieved by culturing in Iscove's Modified Dulbecco's Media which has allowed streamlining of current isolation procedures.• PIA induction of cytokines, including IL-8 and TNF is dependent on being tethered to the bacterial membrane.• Macrophages can penetrate into a S. epidermidisproduced PIA ‘barrier’.• Immunosuppression of whole blood with dexamethasone unmasks the pathogenic advantage of PIA in S. epidermidisexpressing PIA compared to negative controls.• Whole blood killing of S. epidermidisis dependent on CD1 lb/CD 18.• PIA induces whole blood killing dysfunction which is likely related to C5a production.• PIA can be produced in a whole blood environment.• Inocula of -1 0 colony forming unit of S. epidermidisare required to form biofilms in whole blood.This study suggests the importance of studying clinically important biofilm production mechanisms under conditions that closely resemble those in human disease

High heterogeneity of malaria transmission and a large sub-patent and diverse reservoir of infection in Wusab As Safil district, Republic of Yemen.
BACKGROUND: Yemen remains the country with the highest malaria transmission within the Arabian Peninsula and a source of imported cases to neighbouring countries. METHODS: This study collected samples from individuals resident in a valley in Western Yemen as a baseline to examine infection prevalence for a future trial. As well as rapid diagnostic test (RDT) and microscopy, a filter paper blood spot was collected for molecular and serological analyses. RESULTS: Samples were collected from 2261 individuals from 12 clusters across a study area of approximately 100 km(2). Plasmodium falciparum infection prevalence was 12.4, 11.1 and 19.6% by RDT, microscopy and polymerase chain reaction (PCR), respectively. RDT and microscopy did not detect 45% of infections present, suggesting many infections were low-density. Infection prevalence and seroprevalence were highly heterogeneous between clusters, with evidence of higher exposure in clusters close to the wadi. The mean multiplicity of infection (MOI) was 2.3 and high heterozygosity and allelic richness were detected. CONCLUSIONS: This highly diverse parasite population suggests a high degree of transmissibility and coupled with the substantial proportion of low-density infections, may pose challenges for malaria control and elimination efforts
The Complex Management of Mechanical Prosthetic Valve Thrombosis
Mechanical prosthetic valve thrombosis (PVT) is a serious condition that is associated with various life-threatening complications. The utilization of multimodality imaging techniques is critical in identifying this etiology. Its management is complex and often requires repeat surgical valve replacements. Our report describes the case of a 48-year-old female who presented with mechanical mitral valve thrombosis in the setting of subtherapeutic anticoagulation. Due to her complex surgical history, nonsurgical therapeutic options were initially pursued for management. Through shared decision-making and after exhaustion of other alternatives, she was maintained on optimized medical therapy and was scheduled for repeat elective surgery. After compliance with medical therapy and close monitoring, she improved significantly, and her underlying pathology completely resolved, eliminating the need for surgery. This report indicates that the management of mechanical prosthetic valve thrombosis should be individualized and emphasizes the importance of involving a multidisciplinary team of medical and surgical professionals to achieve the best clinical outcomes
