A Systematic Mapping Study of Cloud Resources Management and Scalability in Brokering, Scheduling, Capacity Planning and Elasticity
Isaac Odun-Ayo, Olasupo Ajayi, Rowland Goddy-Worlu and Jamaiah Yahaya
Cloud computing allows for resource management through various means. Some of these include brokering, scheduling, elasticity and capacity planning and these processes helps in facilitating service utilization. Determining a particular research area especially in terms of resources management and scalability in the cloud is usually a cumbersome process for a researcher, hence the need for reviews and paper surveys in identifying potential research gaps. The objective of this work was to carry out a systematic mapping study of resources management and scalability in the cloud. A systematic mapping study offers a summarized overview of studies that have been carried out in a particular area of interest. It then presents the results of such overviews graphically using a map. Although, the systematic mapping process requires less effort, the results are more coarse-grained. In this study, analysis of publications were done based on their topics, research type and contribution facets. These publications were on research works which focused on resource management, scheduling, capacity planning, scalability and elasticity. This study classified publications into research facets viz., evaluation, validation, solution, philosophical, option and experience and contribution facets based on metrics, tools, processes, models and methods used. Obtained results showed that 31.3% of the considered publications focused on evaluation based research, 19.85% on validation and 32% on processes. About 2.4% focused on metric for capacity planning, 5.6% focused on tools relating to resource management, while 5.6 and 8% of the publications were on model for capacity planning and scheduling method, respectively. Research works focusing on validating capacity planning and elasticity were the least at 2.29 and 0.76%, respectively. This study clearly identified gaps in the field of resources management and scalability in the cloud which should stimulate interest for further studies by both researchers and industry practitioners.

Omotola Ezenwoke, Azubuike Ezenwoke, Damilola Eluyela and Olamide Olusanmi
Accounting Information Systems automates accounting information. In prior literature, there is no consensus as to research areas to be included or excluded from AIS researches, coupled with the relatively scarce literature on AIS. The objective of this paper was to quantitatively analyze the volume and impact of AIS literature. Research documents retrieved from the Scopus database were based on defined search terms relating to Accounting Information System (AIS). A bibliometric approach was employed to quantitatively analyze the volume and impact of 727 publications in the AIS research domain, this study focussed on determining the yearly distribution, national contributions, authorship patterns, leading prolific authors, productive institutions, publication outlets, documents types, key issues, citation trends of AIS research publication from 1975-2017. Key findings in this work indicated that there was no steady growth in volume of AIS research publication, Malaysia was the only developing country that featured as one of the top 10 national contributors to AIS research with China and Indonesia being the only emerging economies, also only 159 authors contribute to the 727 publications on AIS research, double authored publications had the highest number of publication as against others, only 5 of the top 10 outlets of AIS research were core accounting outlets, asides the obvious keywords of ‘accounting information system’, ‘information system’ keywords such as Internal Controls, Auditing, Regulatory Compliance, Management Control were the most dominant. While AIS adoption is becoming the mainstream in most developed countries, more investments in ICTs deployment and education will enable developing countries to reap the benefits of these innovations.

Impact Social, Environmental, Physical Fitness and Psychology on Physical Activity among Hearing Impairment Adolescent Girls’: Theoretical Model
Shokhan Omar Abdulrahman, Mohd Radzani Abdul Razak, Mohd Hanafi Mohd Yasin and M.A. Dauwed
Much work has already been conducted in laying the foundations for physical activity (PA) in adolescents, whereby routine involvement in PA comprises a vital part of a healthy and active lifestyle. To achieve a healthy lifestyle, the determining factors of PA among adolescents should be well understood which would in turn lead to intervention strategies promoting PA behaviors. Recommendations for increased PA have been integrated with many guidelines, including those from the world health organization (WHO) with the ‘move for health’ program. However, despite all these guidelines, there are still many people reported to be physically inactive. This study aimed to investigate the success factors related for social support, environmental, psychology and health-related fitness for PA among adolescent girls with hearing impairments. By utilizing three well-known theoretical frameworks to further investigate the barriers and facilitate PA among this age group: Social cognitive theory (SCT), Theory of planned behavior (TPB) and Self-determination theory (SDT). A model was proposed to improve PA level in Iraq. Utilization of other frameworks was not recommended according to the literature as it implies different needs, making it difficult to fit certain cultural or geographical conditions in Iraq. The social support, environmental, psychology and health-related fitness factors have been investigated as the main antecedents that may affect the PA level for adolescent girls with hearing impairments. This help to combine and verify the relationship and effects among the proposed factors and domains in the model.

Azzah Ibrahim Alghamdi and Ibtisam Mohammed Ababutain
Background and Objective: Choosing the appropriate antibiotics (bacteriostatic or bactericidal) considered the most important aspect of treatment. This study aimed to determine the type of inhibitory activity of Eucalyptus camaldulensis’s leaves and bark extracts whether it is bacteriostatic or bactericidal. Materials and Methods: The antibacterial activity of E. camaldulensis leaves and bark extracts were assessed against four bacterial isolates (Pseudomonas aeruginosa ATCC27853, Escherichia coli ATCC25922, Bacillus subtilis and Staphylococcus aureus ATCC24213). Minimum Inhibitory Concentration (MIC) was estimated using a 2-fold dilution method and Minimum Bactericidal Concentration (MBC) was estimated using a pour plate method. The bactericidal effect was estimated by calculating the ratio between MIC and MBC. Qualitative phytochemical assays were performed using a standard method and GC-MS analysis. Results: The results showed that the E. camaldulensis extracts have inhibitory activity against all tested bacteria. The results also indicated that the MBC/MIC ratios of E. camaldulensis extracts were one to two-fold dilutions which are considered as a bactericidal effect. The result of qualitative phytochemical assays showed the presence of tannin, saponins, flavonoid, carbohydrate and protein compounds in all leaves and bark extracts. The results of the GC-MS analysis showed that E. camaldulensis extracts possess a variation in chemical constituents. Some of these compounds have an anti-microbial effect like Cyclononasiloxane, octadecamethyl-, 17-Pentatriacontene, 4H-Pyran-4-one, 3,5-dihydroxy-2-methyl- and Phytol. Conclusion: E. camaldulensis may be used as a natural antibiotic for its bactericidal effect to treat serious infections caused by pathogenic bacteria.

Nguyen Cam Nhung and Tran Thi Thanh Huyen
Background and Objective: The State Bank of Vietnam (SBV) announced it would adopt the flexible exchange rate mechanism commencing Jan 4th, 2016. The exchange rate is regarded as one of the crucial issues affecting the macroeconomic stability of the economy, along with other issues such as the budget deficit, trade deficit and inflation. The objective of this paper was to investigate in greater detail than had previously been considered the degree of exchange rate pass-through (ERPT) into Vietnam’s import prices from its main trading partners. Materials and Methods: Examination of the degree of ERPT into 261 commodities at the HS 4 digit level belonging to major categories of Vietnam imports by conducting Fixed Effects Model and using monthly highly disaggregated data of Korea, Japan, EU-28, Taiwan, Thailand, Singapore and China. Results: The analysis showed that exporters tend to highly pass-through into the import prices in the categories of “Electric machinery” and “Machinery and mechanical appliances”. Besides the prevalence of the U.S. dollar in payment invoices for imports into Vietnam, Japanese Yen (JPY), Euro (EUR) and Singapore dollar (SGD) also appeared in the bill of commodities imported from Japan, EU-28 and Singapore. Conclusion: This paper supported the decision of the SBV in moving toward a more flexible exchange rate regime allowing the daily reference rate based on a weighted average of Vietnamese dong prices in the interbank market in the previous day's trading against prices of major foreign currencies. However, the VND should only be anchored to a basket of 5 currencies, namely USD, JPY, CNY, EUR and SGD, rather than the 8 currencies announced by the SBV on December 31st, 2015.

Background and Objectives: Antioxidants are able to stabilize or eliminate free radicals before they attack the cells. Antioxidant compounds such as flavonoid substances are essential for maintaining optimum cellular work. Phenol and flavonoid compounds are widely contained in plants, included in strawberry. The purposes of this research were to compare antioxidant profiles from different organs of strawberry using two antioxidant testing methods 2,2-diphenyl-1-picrylhydrazyl (DPPH) and Cupric reducing antioxidant capacities (CUPRAC) and also its phytochemical content. Materials and Methods: Antioxidant activities, total phenolic content (TPC) and total flavonoid content (TFC) were conducted by UV-Vis spectrophotometry. Correlation of TPC and TFC with their IC50 of DPPH and EC50 CUPRAC were analyzed by Pearson’s method. Results: All different organs extracts of strawberry exposed IC50 of DPPH varied from 0.22-10.14 μg mL–1 and EC50 of CUPRAC from 130.42-250.14 μg mL–1. Ethanol stem extract gave the highest TPC 18.62 g gallic acid equivalent (GAE) 100 g–1, while ethyl acetate leaves extract showed the highest TFC 7.40 g quercetin equivalent (QE) 100 g–1. The TPC in fruit and leaves extract were significantly negative correlation with their IC50 DPPH (r = -0.865; r = -0.970, p<0.01). Conclusion: All different organs extracts of strawberry were very strong antioxidant by DPPH method. Waste products of strawberry (leaves and stem) had antioxidant potential. The major contributor in antioxidant activities of fruit and leaves extracts by DPPH assay were phenolic compounds. Only strawberry fruits extract showed linear results in DPPH and CUPRAC assays.
