Mobile versus PC: Does Device Type Affect Online Survey Response Quality for Tourism Research?

The use of mobile devices to complete online surveys is trending upward and is likely to continue unabated for some time. With this growth, there is a growing interest in how to make mobile devices a viable way to administer self-report online surveys among researchers. Utilizing a large-scale online panel survey, the current study compares the quality and pattern of responses collected from mobile device respondents to those collected from PC/laptop respondents. It is found that although mobile respondents tended to provide shorter answers to open-ended questions than PC/laptop respondents, response quality was not significantly different between the two groups. Additionally, compared to PC/laptop respondents, mobile device respondents were younger, more likely to be female and with a higher income level. Practical implications related to our research findings are also discussed

Nano Fe3O4-activated carbon composites for aqueous supercapacitors

In this study, a symmetric supercapacitor has been fabricated by adopting the nanostructured iron oxide (Fe3O4)-activated carbon (AC) composite as the core electrode materials. The composite electrodes were prepared via a facile mechanical mixing process and PTFE polymeric solution has been used as the electrode material binder. Structural analysis of the nanocomposite electrodes were characterized by scanning electron microscopy (SEM) and Brunauer-Emmett-Teller (BET) analysis. The electrochemical performances of the prepared supercapacitor were studied using cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) in 1.0 M Na2SO3 and 1.0 M Na2SO4 aqueous solutions, respectively. The experimental results showed that the highest specific capacitance of 43 F/g is achieved with a fairly low Fe3O4 nanomaterials loading (4 wt. %) in 1 M Na2SO3. It is clear that the low concentration of nanostructured Fe3O4 has improved the capacitive performance of the composite via pseudocapacitance charge storage mechanism as well as the enhancement on the specific surface areas of the electrode. However, further increasing of the Fe3O4 content in the electrode is found to distort the capacitive performance and deteriorate the specific surface area of the electrode, mainly due to the aggregation of the Fe3O4 particles within the composite. Additionally, the CV results showed that the Fe3O4/AC nanocomposite electrode in Na2SO3 electrolyte exhibits a better charge storage performance if compared with Na2SO4 solution. It is believed that Fe3O4 nanoparticles can provide favourable surface adsorption sites for sulphite (SO32-) anions which act as catalysts for subsequent redox and intercalation reactions

Enabling quantitative data analysis through e-infrastructures

This paper discusses how quantitative data analysis in the social sciences can engage with and exploit an e-Infrastructure. We highlight how a number of activities which are central to quantitative data analysis, referred to as ‘data management’, can benefit from e-infrastructure support. We conclude by discussing how these issues are relevant to the DAMES (Data Management through e-Social Science) research Node, an ongoing project that aims to develop e-Infrastructural resources for quantitative data analysis in the social sciences

Ethambutol ocular toxicity in a patient with pulmonary tuberculosis a case report

Purpose. To highlight the importance of using the Farnsworth Panel D-15 Hue test in colour vision testing in patients on ethambutol treatment. Case Report. A 70 year-old lady received ethambutol as part of her anti-tuberculous regime. She developed blue-yellow colour defect detectable with the Farnsworth Panel D-15 Hue test, but not with the Isihara Pseudoisochromatic Plates. Ethambutol was immediately discontinued from her anti-tuberculous regime. Two months later, her colour vision returned to normal. Conclusion. This case report illustrates the importance of regular monitoring of patients receiving ethambutol for blue-yellow colour defect using the Farnsworth Panel D-15 Hue Test

The importance of ophthalmic signs in the diagnosis of suprasellar meningioma - A case report

A forty-two year old lady presented with gradual, painless, progressive blurring of vision of her left eye for four months. There were no other associated ocular or systemic complaints. Examination showed decreased visual acuity in both eyes and a pale optic disc on the left side. Visual field examination revealed a temporal field defect of the right eye which aroused the suspicion of an intracranial mass lesion. MRI of her brain revealed a suprasellar meningioma. We would like to emphasize the importance of visual field examination of both eyes in patients presenting with unilateral loss of vision

Neonatal conjunctivitis a review

Ophthalmia neonatorum remains a significant cause of ocular morbidity, blindness and even death in underdeveloped countries. The organisms causing ophthalmia neonatorum are acquired mainly from the mother’s birth canal during delivery and a small percentage of cases are acquired by other ways. Chlamydia and Neisseria are the most common pathogens responsible for the perinatal infection. Fortunately in most cases, laboratory studies can identify the causative organism and unlike other form of conjunctivitis, this perinatal ocular infection has to be treated with systemic antibiotics to prevent systemic colonization of the organism. Routine prophylaxis with 1% silver nitrate solution (crédés method) has been discontinued in many developed nations for the fear of development of chemical conjunctivitis
