Stress in higher education: a study of mismatched instruction as a contributing factor in female Emirati undergraduate students

Dunn and Dunn (1992) have proposed that given responsive environments, students attain statistically higher achievement and aptitude test scores in matched, rather than mismatched treatments . Therefore, matching educational settings and activities to students\u27 learning preferences and strengths places them within their academic comfort zone, which leads to an increase in their academic motivation and achievement. Conversely, this paper proposes that a continuing mismatch between educational settings/activities and learning preferences/strengths may frustrate students and put them at a disadvantage which results in a higher level of anxiety and stress. The aim of this project is to study the relationship between learning styles, teaching methods and level of students\u27 stress. More specifically, the effect of mismatched instruction on students\u27 stress levels was investigated, and found to increase both physiological and psychological indicators of stress

Financial and Economic Evaluation of Germinated Barley cultivation in South of Red Sea Governorate

The research aimed to study the financial evaluation of the cultivar barley units in the Shalateen area in the Red Sea Governorate, as one of the means used in providing green fodder for animal feeding, especially sheep, goats and camels. The research led to a set of results, including: (1) net present value when the discount rate is 9% about 2.445 million pounds, which indicates the feasibility of investment in this activity. (2) the internal rate of Return(IRR) was about 33.53%, which is more than the borrowing interest of the capital represented by the prevailing commercial interest rate, which confirms the feasibility of investing in the activity of cultivated barley. (3) the benifit cost ratio was estimated at 1.176 any larger than one, which indicates the feasibility of the investment. (4) the Pay-back Period (PBP) was estimated at 1.714 years, which indicates the possibility of recovering the invested capital within two years from the start of the project . (5) the return on investment rate was about 27.12 %.(6) sensitivity analysis of barley cultivation units has been carried out, however, the internal rate of Return is still greater than the opportunity cost of capital investment in the community and therefore it is recommended to make the decision to accept investment in barley cultivation units. Therefore, the research recommends the need for expansion in the cultivation of cultivar barley, especially in desert areas with low pastoral Plants

Risk factors for road traffic accidents in Gulu municipality, Uganda

Background: Currently Road Traffic Accidents (RTA) are ranked tenth among the leading causes of death and ninth among all leading causes of disability worldwide. There has been no published study on RTA in Gulu municipality. There is a high frequency of RTA in Gulu municipality with poor road design and inadequate knowledge on road safety precaution among road users.Objectives: To establish the causes of Road Traffic Accidents (RTA), establish the safety measures in place to protect road users to avoid RTA and establish people mostly involved and the mechanism of RTA.Design: A cross-sectional studySettings:Four divisions of Gulu Municipality; Layibi, Laroo, Pece and Bardege.Subjects: Two hundred and forty two participants including pedestrians, drivers of different categories of vehicles, motorcyclists and bicyclists locally known as bodaboda and the police were interviewed.Results: Most respondents reported RTA as a problem in Gulu municipality (96%), causing death (48%), financial constraint due to medical treatment (41%) and disability (11%). The following causes of RTA were identified; reckless driving and riding (49%), poor road design (24%), drug abuse (15%) and over loading (12%). According to police records of January to September 2009 RTA involved pedestrians (36.34%), passengers (25.80%), motorcyclists (24.88%), pedal cyclists (11.52%) and drivers (3.68%).Conclusion: RTAs is a substantial burden in Gulu municipality in Northern Uganda with reckless driving or riding, poor road design, overloading, double parking, inadequate road safety signs and knowledge, were major risk factors. Efforts to reduce RTA in Gulu municipality should aim at addressing these problems

The Global Burden of Snakebite: A Literature Analysis and Modelling Based on Regional Estimates of Envenoming and Deaths

Janaka de Silva and colleagues estimate that globally at least 421,000 envenomings and 20,000 deaths occur each year due to snakebite

Selection of Optimal Communication Medium Using Personas

This study is concerned with the apparent gap between knowledge management literature and persona creation guidelines. As the authors recognized that the guidelines don’t seem to advise User Experience professionals to present information how users want to see it. The purpose of this study is to explore how UX professionals negotiate optimal communication medium for information representation. Based on the literature, a conceptual framework was created that consists of communication medium, Personas, and information representation that guided our field research. As such, qualitative interviews were conducted with UX professionals. The purpose being, to explore their experiences with using Personas for negotiating communication medium to present information. Key findings are grouped into two categories relating to Personas and Selection of communication medium. Findings have revealed that practitioners intuitively bridge the aforementioned gap. Therefore, in light of these findings, the Persona creation guidelines may include a point addressing the selection of communication medium for information presentation, such that they may be more in line with their practical implementation. Additionally, practitioners may benefit from adopting a more structured approach to selecting communication medium and integrating it with their Personas

Quantitative Analysis and Comparison of Symmetric Cryptographic Security Algorithms

Nowadays, the rapid evolution of communication systems offers, to a very large percentage of population, access to a huge amount of information and a variety of means to use in order to exchange personal data. Hence the search for the best solution to offer the necessary protection against the data intruders’ attacks along with providing these services in time is one of the most interesting subjects in the security related communities. Cryptography is usually referred to as “the study of secret”. Encryption is the process of converting normal text to unreadable form. There are a variety of encryption algorithms have been developed. This paper provides quantitative analysis and comparison of some symmetric key cryptographic ciphers (DES, 3DES, AES, Blowfish, RC5, and RC6).  The quantitative analysis approach is a step towards optimizing the security operations for an efficient next generation family of network processors with enhanced speed and power performance. A framework will be proposed as a reference model for quantitative analysis of security algorithm mathematical and logical operations.
