Moving towards Electronic Lecturer Evaluation System (E-LEva) in UiTM Pahang: a study across lecturers / Khairul Nizam Abd Halim and Razulaimi Razali

paper investigates the perception and attitudes of non-business major students in Universiti Teknologi MARA (UiTM) towards economics education and their relationship on students’ academic performance. One of the key performance indicators in the academic programme of the university is to achieve less than twenty percent failures in all subjects offered. A four-semester examination results revealed that students constantly obtained high failure rate in two economics introductory subjects. Using students taking these two economics courses as respondents, dimensions of attitudes towards economics education were identified through the use of an exploratory factor analysis. Four factors were extracted from a 26- item questionnaire identified as ‘Value’, ‘Difficulty’, ‘Cognitive’ and ‘Affective’. Cronbach’s Alpha for the four factors was acceptable. The findings suggested that there was no significant difference between male and female students on the four dimensions of attitude even though the achievement of female students’ was higher than males. Students who did not perform were found to have a more negative attitude on the four dimensions of attitude compared to those who performed. Regression of the final exam scores on the four latent variables obtained from the factor analysis revealed that subject difficulty and gender, taken together, were significantly associated with students’ achievemen

Moving towards electronic lecturer evaluation system (E-LEva) in UiTM Pahang: A study across lecturers/Khairul Nizam Abd Halim, Razulaimi Razali

The Electronic Lecturer Evaluation System (E-LEva) is an online system to evaluate the performance of UiTM Pahang lecturers at the end of every semester. The main users of e-LEva are students, the Academic Affairs (HEA) Department of UiTM Pahang and the lecturers. The main purpose of e-LEva is to let the students have a better platform to evaluate their lecturers. The HEA can immediately retrieve the statistics of the evaluation and lecturers can identify the level of the students’ satisfaction regarding the teaching and learning process. This information is also important to inform the lecturers of the quality of their teaching styles implemented in the classroom. The previous traditional process was very complicated and tedious; the process of data compilation itself took more than three months. Thus, the implementation of e-LEva helps the management especially the HEA of UiTM Pahang in reducing time, resources and cost. e-LEva was developed based on the specific requirements identified by the HEA. To fulfill the requirements of the university, academics and students, a lot of improvements have been done on e-LEva within the two years of its implementation. The objective of this paper is to study the feedback of the lecturers in order to investigate the level of acceptance of e-LEva. Data were collected via an online survey questionnaire

Developing multi-tier network design for effective energy consumption of cluster head selection in WSN / Wan Isni Sofiah Wan Din … [et al.]

Clustering in Wireless Sensor Network (WSN) is one of the methods to minimize the energy usage of sensor network. The design of sensor network itself can prolong the lifetime of network. Cluster head in each cluster is an important part in clustering to ensure the lifetime of each sensor node can be preserved as it acts as an intermediary node between the other sensors. Sensor nodes have the limitation of its battery where the battery is impossible to be replaced once it has been deployed. Thus, this paper presents an improvement of clustering algorithm for two-tier network as we named it as Multi-Tier Algorithm (MAP). For the cluster head selection, fuzzy logic approach has been used which it can minimize the energy usage of sensor nodes hence maximize the network lifetime. MAP clustering approach used in this paper covers the average of 100Mx100M network and involves three parameters that worked together in order to select the cluster head which are residual energy, communication cost and centrality. It is concluded that, MAP dominant the lifetime of WSN compared to LEACH and SEP protocols. For the future work, the stability of this algorithm can be verified in detailed via different data and energy

An enhancement of path selection to cluster head based on multi-hop routing in two-tier wireless sensor network

Wireless Sensor Network (WSN) is a distributed wireless connection that consists many wireless sensor devices. It is used to get information from the surrounding activities or the environment and send the details to the user for future work. Due to its advantages, WSN has been widely used to help people to collect, monitor and analyse data. However, the biggest limitation of WSN is about the network lifetime. Usually WSN has a small energy capacity for operation, and after the energy was used up below the threshold value, it will then be declared as a dead node. When this happens, the sensor node cannot receive and send the data until the energy is renewed. To reduce WSN energy consumption, the process of selecting a path to the destination is very important. Currently, the data transmission from sensor nodes to the cluster head uses a single hop which consumes more energy; thus, in this paper the enhancement of previous algorithm, which is MAP, the data transmission will use several paths to reach the cluster head. The best path uses a small amount of energy and will take a short time for packet delivery. The element of Shortest Path First (SPF) Algorithm that is used in a routing protocol will be implemented. It will determine the path based on a cost, in which the decision will be made depending on the lowest cost between several connected paths. By using the MATLAB simulation tool, the performance of SPF algorithm and conventional method will be evaluated. The expected result of SPF implementation will increase the energy consumption in order to prolong the network lifetime for WSN

Fl\ue4mische Belfriede und s\ufcdniederl\ue4ndische st\ue4dtische Bauwerke im Mittelalter: Symbol und Mythos

Feedback from customers is an effective method to identify the quality of services and facilities provided by a university. The effectiveness to respond to customers’ feedback also depends on an effective workflow. By having an effective method and workflow, the action from the management to improve the quality of services and facilities can be done immediately and effectively. The aim of this paper was to describe the development of new complaint management system. Manual process of complaint handling between customers and the university was monitored to develop the new complaint management system. New complaint management system known as e-Aduan was developed. Both customers and management had accessed to the new system to complaint and retrieve information. Through this study the researchers had also identified workflow procedures to be followed by the management to address customers’ complaints and comments. This new scenario produced good impact to both customers and management; customers now had a platform to communicate their dissatisfaction and the management would be able to act immediately upon any customer feedback. Researchers believed e-Aduan and the effective workflow could be applied to other sectors nationally and internationally. The strength of this research was on the combinations of the effective method (e-Aduan) and effective workflow. The implementation of the system indicated there were a lot improvement need to be done on the quality of services and facilities. Further study could be done on identified the real problem automatically from the complaint to improve the effectiveness and performance of the system.
