THE IMPACT OF INDIVIDUAL LEARNING STYLE ON ATTITUDE TOWARDS TELEVISION AS ADVERTISING MEDIA.
Marketing communication through various media has always been important for marketers to build customer relationship. Every individual has their own manner of learning style. Since individuals display significant difference in learning style, marketers should investigate the segmentation of consumers by learning style to improve the effectiveness of marketing communication. VARK learning style model is applied in this study because this model focus on sensory and perceptual processes which are widely utilized in implementing and usage of advertising media. Television being the frequently used advertising media is involved in this research illustrating how consumers in Melaka show their attitudes towards television as advertising media with regards to learning modalities in VARK model. Result is tested if the learning modalities impact the attitude, findings indicate Visual modality has the greatest positive influence on attitude towards television as advertising media, followed by Auditory modality. In contrast, Kinesthetic modality has the greatest negative influence on attitude towards television as advertising media, followed by Read/Write modality. The findings also indicate the four modalities in VARK model has significance on the attitude towards television as advertising media. Results of analysis also show that dominant learning modality exist in this research study

Speed Analysis along Ipoh-Lumut Highway
Speed is an important transportation consideration because it relates to safety, time, comfort,
convenience and economics. Due to development of lpoh-Lumut Corridor, the need to
address the growing traffic volume and safety on lpoh-Lumut Highway arises. Speed is also
related to Level of Service (LOS) characteristic of a particular highway. This study aims to
assess the general roadway speed on lpoh-Lumut Highway and to propose new set of speed
limit. lpoh-Lumut Highway is being demarcated by normal car odometer during a trial run
from Ipoh to Lumut. Spot speed studies will be conducted in stretches demarcated. Based on
the similar study conducted in United States of America, speed data collected will be used to
set a speed zone along Ipoh-Lumut Highway. Literatures have supported that using 85th
percentile speed to set an appropriate speed limit will result in a reduction in crashes and an
increase in Level of Service
Study on C02 Absorption in Single MEA and Mixed MEA & DEA
Theoverall effect of greenhouse warming caused by increasing amount of carbon dioxide
(CO2) in the atmosphere has lead to growing interest in research for new methods to
reduce the C02 emissions. One such alternative is to recover C02 from flue gas by
chemical absorption with alkanolamines, which can be then used for CO2 sequestration.
Alkanolamines have long been used for removing CO2 and hydrogen sulfide (H2S) from
natural gas streams. The classes of alkanolamines are divided into primary amines
(monoethanolamine, MEA), secondary amines (diethanolamine, DEA) and tertiary
amines (monodiethanolamine, MDEA). The objectives of this study are to study the
effect of solvent flow rate and amine concentration in effective CO2 removal as well as to
recommend optimum percentage of mixed primary and secondary amines for efficient
C02 absorption. The use of mixture of primary and secondary amines would maximize
the individual properties of the single amines. The experiment was conducted in a wetted
wall gas absorption column with variousMEA concentrations, varying solvent flow rate
and varying mixtures of amines. From the experiment, the effect of increasing solvent
flow rate would lead to overall better CO2 removal. For solvent concentration, an
increase of amine concentration would increase the maximum overall CO2 removal
efficiency. The optimum blend of amines from this study is reported as DEA-25wt% and
MEA-10.2wt% based on the maximum total moles of C02 effectively removed with this
blend. From this study, the main factor which drives the C02 absorption process in a
mixed amine system is the concentration of MEA in the mixture. A decrease in MEA
concentration would lead to a decrease in the total moles of CO2 removed
TECHNOLOGICAL INNOVATION ACTIVITIES IN FIRMS AND PROPENSITY OF INDIVIDUALS STARTING NEW BUSINESSES
Prior studies have found that knowledge gained from work experience is a way to gather insights for business opportunity recognition. However, little is known about the specific types of knowledge that lead to business founding. Utilizing concepts from knowledge spillovers and from the opportunity recognition literatures, this paper argues that through an organization’s technological innovation activities, employees develop specialized knowledge that provides them with the entrepreneurial opportunities to found new businesses. Besides highlighting the positive relationship between technological innovation activities in organizations and the propensity of individuals leaving the organizations to start new businesses, this paper also provides a more fine-grained explanation of the types of technological innovation activities that can lead to business founding. We argue that knowledge acquired through product innovations is more easily appropriated by individuals for commercial uses, while knowledge acquired through process innovations must be integrated with other parts of the organization to be valuable. This study proposes that product innovation activities in an organization more so than process innovation activities in an organization are related to new business founding. Implications for opportunity exploitation and ways to appropriate knowledge spillovers are discussed.
Ray transfer matrix for a spiral phase plate
We present a ray transfer matrix for a spiral phase plate. Using this matrix,
we determine the stability of an optical resonator made of two spiral phase
plates, and trace stable ray orbits in the resonator. Our results should be
relevant to laser physics, optical micromanipulation, quantum information and
optomechanics.Comment: 5 pages, 3 figure
Entrepreneurial intentions: The influence of organizational and individual factors
An individual's intent to pursue an entrepreneurial career can result from the work environment and from personal factors. Drawing on the entrepreneurial intentions and the person–environment (P–E) fit literatures, and applying a multilevel perspective, we examine why individuals intend to leave their jobs to start business ventures. Findings, using a sample of 4192 IT professionals in Singapore, suggest that work environments with an unfavorable innovation climate and/or lack of technical excellence incentives influence entrepreneurial intentions, through low job satisfaction. Moderating effects suggest that an individual's innovation orientation strengthens the work-environment to job-satisfaction relationship; selfefficacy strengthens the job-satisfaction to entrepreneurial intentions relationship.Entrepreneurial intentions Job satisfaction Self-efficacy
What Types of Feedback do Undergraduate Chemistry Students Give Each Other? A Case Study from Singapore
This study was part of a larger project to improve learning of undergraduate chemistry in Singapore through the use of self-authored three-tier multiple-choice questions (3TMCQs) and the giving/receiving of peer feedback. Specifically, we examined the quality of written feedback based on the classification by Hattie and Timperley (2007) that year 2 to 4 learners (N=31) gave each other on responses in their 3TMCQs (N=466 administered). It was found that the most common type of voluntary feedback given by test-makers was task (& self), followed by process (& self), self alone, and lastly regulation (& self) levels over seven chemistry courses. In addition, question type (based on revised Bloom’s Taxonomy) had a marginal effect on the quality of feedback received; instead, items answered incorrectly garnered higher quality feedback and were four times more important than the cognitive level of questions. Feedback quality given by more experienced students was also no better than those given by less experienced ones. While there is growing evidence supporting the self-authoring of questions and giving/receiving peer feedback to enhance learning at undergraduate levels, further research is warranted into the types of peer feedback that learners may receive when attempting different question formats
