A Case Study on Peer Review and Lecturer Evaluations in an Academic Setting
Nor Kamaliana Khamis,Abu Bakar Sulong,Baba Md Deros
Asian Social Science , 2012, DOI: 10.5539/ass.v8n16p192
Abstract: Students can enhance their soft skills and learning experience through the use of group projects. However, evaluating group project performance has become very challenging. This paper presents the concept of group management in measuring individual performance in group projects in an academic setting. Individual performances in similar courses were also compared based on two consecutive semesters (Semesters 1 and 2). The respondents for this study were first year students who attended similar courses for both semesters. Performance measurement was based on peer review and lecturer evaluations. The criteria for these evaluations were similar for both semesters. The current study aims to determine the weaknesses and strengths of an individual in a group, and relate them with group performance based on the individual presentation marks. The study also analyzes the relationship between these two performance tools. Findings indicate that peer review and lecturer evaluations can be used to determine the performance of students in a group project, and that these two evaluation tools are not significantly correlated.

Baba Md Deros,Suzana Mohammed Zohdi,Darliana Mohamad,Nor Kamaliana Khamis
Asian Social Science , 2012, DOI: 10.5539/ass.v8n16p232
Abstract: The main purpose of this survey is to get industrial employers’ feedback on the reasons for their lack of involvement in National Dual Training System (NDTS) organized by the Department of Skills Development, Ministry of Human Resources Malaysia. Industrial employers’ involvement and support is very important in ensuring NDTS implementation success. Therefore, it is very critical to identify factors and barriers that hinder industrial sectors from participating in NDTS program. A survey questionnaire was developed to act as a data collection instrument. Survey questionnaire was sent to 5,000 companies comprising of multinationals, small and medium-sized industries. However, only 509 companies returned the completed questionnaires giving a low response rate of 10.18%. Survey results revealed the following factors hinders industrial sectors from participating in NDTS program; they are: training culture, organizational structure, financial and physical resources, policies, NDTS awareness, employer’s commitment and technological factors. In addition, survey result showed respondents companies have good training culture; however, they tend to focus on-the-job training. Majority of respondents did not participate in the NDTS because they were not aware about its existence and no information or publicity materials made available to them. Therefore, the authors strongly suggest the Department of Skills Development, Ministry of Human Resources Malaysia to enhance their promotion and publicity campaign on NDTS program to industrial sectors.

International Journal of Electrical and Computer Engineering , 2012, DOI: 10.11591/ijece.v2i6.1222
Abstract: This paper is a brief review of Rain AttenuationModelling and Mitigation in the Tropics. The fast depleting availability of the lower frequency bands like the Ku-band as a result of congestion by commercial satellite operations coupled with severe rain attenuations experienced at higher frequency bands (Ka and Q/V), particularly in the tropical regions which was caused by higher rainfall rates and bigger raindrop size, amongst others; it was pertinent that deliberate effforts be geared towards research along this direction. This became even more critical owing to a dearth database along the slant path in the tropical regions for use in rain propagation studies at microwave frequencies, especially at millimeter wave bands (where most signal depolarization and fading takes place). The results presented in this work are valuable for design and planning of the satellite link, particularly in the tropical regions.DAH, ITU-R and SAM model simulations along the slant-path were investigated using local rainfall data at 0.01% of the time, while making use of TRMM data from NigComSat-1 satellite to obtain the measured data for Lagos. Terrestrial attenuation data for 0.01% of the time for UTM were obtained from the UTM wireless communication center (WCC). The attenuation data were thereafter transformed to slant path using transformation technique proposed for Ku band byA. Y. Abdulrahman. Theattenuation exceeded for other percentages of the average year was obtained using statistical interpolation extrapolation method.It was observed that the proposed model predicts creditably well for the ka down link frequency band, by producing the best performance when compared with SAM, DAH and ITU-R models

International Education Studies , 2009, DOI: 10.5539/ies.v2n4p168
Abstract: Food safety issue is not new in Malaysia as problems such as unsafe food handling, doubtful food preparation, food poisoning outbreaks in schools and education institutions and spreading of infectious food borne illness has been discussed by the public more often than before. The purpose of this study is to examine the food safety knowledge and attitude of culinary based students from four (4) public and private higher learning institutions (IPT) with prior knowledge on food safety, hygiene and sanitation. The study involved a total of 114 group administered questionnaires that were usable and coded comprising of 37- questions assessing their knowledge and attitude on food safety. A series of analysis were conducted to test the significant relationship between food safety knowledge and food safety attitude and seek any differences based on the studentsa demographic profiles. The research finds that higher learning institutiona s students who have prior knowledge on food safety partly do not represent their attitude towards food safety although their correlations recorded moderate positive relationships especially on personal hygiene practice (p=0.07, r=0.42) and keeping food at safe temperature (p=0.17, r=0.36). On the other hand, their knowledge in avoiding cross contamination (p=0.00, r=0.50) and avoiding food from unsafe sources (p=0.02, r=0.36) were positive and significant in influencing their food safety attitude. The finding also revealed that there were no significant differences among food safety knowledge and attitude based on the studentsa demographic profiles. The results urged for more improvement in both knowledge and practice of food safety among students in public and private higher learning institutions towards recommended food safety standards and positive attitude in food preparation process.

Health (Health) , 2013, DOI: 10.4236/health.2013.59203

Background and Objective: There is a rising concern about Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome (HIV/AIDS) related knowledge in rural communities of Sudan. This study focuses on determining the extend of knowledge, beliefs, and attitudes about HIV/ AIDS among rural communities difficult to access in the six States of Sudan. Subjects and Methods: Six thousand and one hundred twenty five respondents were interviewed through the method of house-to-house visits. A structured questionnaire was administered by research assistants recruited from the Faculty of Medicine, Khartoum University during a rural residency campaign in six states of Central, Eastern and Northern Sudan during 2008/2009. Results: Of the total interviewees, 48% were aware of the HIV/AIDS risk; 46% reported to have good health seeking behaviors for HIV/AIDS. 54.4% of women reported to have better knowledge about the disease than men (45.6%). 38% (2005) had not heard of safety use of condom whereas 16% (320) had used it. Logistic regression revealed that 5.3% of knowledge about the disease was explained by gender, education and religion adjusted over age of the respondents. Conclusions: Mass media were the most common source of information about the existent risk of HIV/AIDS in rural communities. These findings could assist Sudanese National Aids Programme (SNAP), healthcare providers and policymakers to develop informative materials and health education programs to educate rural community is about the risk of HIV/AIDS.

Open Journal of Epidemiology (OJEpi) , 2016, DOI: 10.4236/ojepi.2016.61003
Abstract: Background: The well-established DMFT index has been used for over 75 years as a key for measuring dental caries in dentistry. DMFT is applied to permanent dentition and expressed as the total number of teeth decayed (D), missing (M), or filled (F), tooth (T) in an individual. Objectives: The objective of this study is to build a mathematical model for the existing DMFT index and compare its parameters by suggested new mathematical model. Mathematical Models: Fixed Model: Is a mathematical model for the existing DMFT index and will be considered as fixed model; in which all individuals under screening will have the same probability θ, 0 ≤ θ ≤1 of dental caries. In this fixed model the unit of the screening is the individual, and will be evaluated for caries as a dichotomous (0, 1) variable. Random Model: The new suggested model is a random model that suggests a mouth of an individual as an environment and the tooth is a unit of research. In this random model, only the teeth in one mouth have the same probability θ, 0 ≤ θi ≤ 1 where i?=1, 2...,k?; number of screening individuals. Expected Outcome: Mathematically, the fixed model will highlight what the value 1 will hide as information and hence this may explain why the average of DMFT is may be overestimated for any sample studied using fixed model. The random model will yield a cumulative weighed probability on the function of the number of teeth screened per mouth θ, 0 ≤ θ ≤ 1, hence the average DMFT index will be weighed against the number of teeth screened per all subjects. Conclusion: The random model yields an average and more realistic expected value for the population studied. Furthermore, in such model, it is easy to estimate the variance and it is obvious that this model yields the smallest variance.

Abstract: This research aims to study various Symmetrical Algorithms, while the main objective of this study is to find out a suitable algorithm for the encryption of any specific size of text file where the experiment of each algorithm is based on encryption of different sizes of the text files, which are in “10 KB to 5 MB”, and also to calculate the time duration that each algorithm takes to encrypt or to decrypt the particular size of each text file. There are many types of encryption algorithm, which can be used to encrypt the computerized information in different Organizations, whose all algorithms can encrypt and decrypt any size of text file, but the time duration of each Algorithm during the encryption or decryption process of specific file size is not fixed. Some of the algorithms are suitable for encryption of specific ranges of the file size, or some of algorithms are functional while encryption small size of files, and others algorithms are functional for encryption of big size of text files, based on the time duration disparity among symmetric algorithms during encryption of text files. In this study five symmetrical algorithms are merged in one program using classes and concept of inheritance in the form that if encryption is needed, the program will select the file and it checks the size of the text file. After this process the program automatically will select the suitable encryption algorithm to encrypt the specific text file according to the range of the file size. Knowing that the file size before or after encryption will not change or is stable, in this case of the decryption algorithm will apply the same process of encryption while decrypting files, the program of encryption and decryption code will write using visual Studio 2013. The result will be analyzed with R program (R software), the cipher text will appear in the format of UTF8 which means Unicode Transformation Format, “8” Means “8” bits to represent a character, the size format that will apply in the program will be in format of KB (kilo Byte).

Matematika , 2000,
Abstract: Linear structural relation or LISREL has been adopted to checkthe relationship between observable variables and latent variables, which reflect to the quality of life. The formation of measurement model and structural model has been able to explain the relation between observable variable and latent variables and between latent variables and latent variables. As many as 15 variables which represent three factors have been taken into consideration in the measurement of quality of life (QOL) index, i.e. socioeconomic factor, demography structure factor and family size formation factor. An example of index measurement has been presented and lastly the QOL index based on three factors is listed according to district and state. It has been found that 59.5% of the districts in Peninsular are below the minimum level, whereas the Federal Territory is at the highest index and Kedah records the lowest index.

Abstract: Although many studies examined the existence of spatial pattern of unemployment in some developing and many developed countries in improving the prosperity or social status and reducing the inequalities in unemployment between areas of such country, there is still much work to be done. Some of these studies were found spatial pattern for unemployment using different statistical techniques and geographical mapping. Question is raised whether the spatial pattern of unemployment is existed in Iraq? The objective is to investigate the spatial structure of unemployment rate (UR) across different governorates to provide implications for policy makers, investigating the hot spots of UR, and showing visual picture for UR. The study utilized a cross-sectional census data for 18 governorates collected in 2007. Mapping was used as a first step to conduct visual inspection for UR using quartiles. Two statistics of spatial autocorrelation, based on sharing boundary neighbours, known as global and local Moran's I, were carried out for examining the global clustering and local clusters respectively. Based on visual inspection of mapping, the global clustering was found in UR and it was confirmed by the significant statistic found by global Moran’s I . Out of 18, seven governorates: 3, 4, 5, 12, 15, 16, and 17 were found as local clusters in UR based on local Moran's I. In conclusion, the UR varied across different governorates with black spots in northern and southern parts of the country.
