Abstract

The Best Management Practices for Sustainable Urban Drainage System including On-Site Detention have been introduced in the Storm Water Management Manual for Malaysia. Flash floods are becoming frequent in the urbanised areas in this country. Inefficient drainage system has been highlighted as one of the factors. Urban drains were reported incapable of coping with the unexpected heavy rainfall. Concrete drains are favourable in construction industry for economic reasons. An experimental research was conducted out to investigate the effectiveness of infiltration integration with drainage system to reduce flash flood. This laboratory research was conducted in the Universiti Teknologi Malaysia. Experiments were performed for selected drainage bed slopes and focussed on several spacing between precast drain sections along the system. The total and infiltrated flow rates, water surface and velocity profiles were examined. The results showed that drain flow rates were reduced by 60.9%–89.6% when the spacing between drain sections were enlarged. Meanwhile, the flow depths in drain sections were dropped by 48.2%–68.9%, and the water velocity was lowered up to 49% as the spacing between drain sections were increased. The study found that the drainage bed slope also influenced the performance of the infiltrated concrete drainage system.

Abstract

Purpose

The aim of this study was to evaluate anti-bacterial anti-fungal activity of six Lamiaceae family coleus plants based on their traditional uses (breast-milk stimulants) from two Asian countries (Malaysia and Indonesia).

Design/methodology/approach

Plants leaves of coleus species were collected from Kuantan (Malaysia) and Jakarta (Indonesia). From Kuantan, Coleus aromaticus – Malaysia (CATM), Pogostemon cablin – Malaysia (PCM), Coleus blumei-purple leaves – Malaysia (CBPM), Coleus blumei-red leaves – Malaysia (CBRM), Coleus amboinicus – Malaysia (CALM) and from Jakarta Coleus amboinicus – Indonesia (CALI) were collected freeze dried and extracted with aqueous methanol. The antimicrobial activity of the extract was determined by making use of macro dilution and disc diffusion methods. The selected bacteria and fungus used were namely Bacillus subtilis and Staphylococcus aureus (gram positive) and Escherichia coli and Pseudomonas aeruginosa (gram negative) and Candida albicans (a fungi).

Findings

All leaf extracts showed activity at least against one strain of bacteria and the result shows that there were significant differences (p<0.05) between the activities on microorganism. The minimum inhibitory concentration of all leaves extracts ranged from 1.0 to 2.0 mg/ml in inhibiting the growth of S. aureus, E. coli, P. aeruginosa and B. subtilis. This study shows that the coleus plants leaves can be used as anti-bacterial anti-fungal agent apart from the breast-milk stimulation properties.

Research limitations/implications

This research was carried out with a limited grant and it was not possible to study some more aspects, for example, the composition and the active components isolation, etc. Furthermore, to establish the relationship among the components and bacteria or fungus, etc.

Practical implications

This research would have greater impact since the leaves of coleus plants are already in use in some communities for the purpose of breast-milk stimulation and insect bite therapy and many more.

Originality/value

This research takes into consideration the effect of coleus plants on a few bacteria and a fungus which have never been studied before.

Abstract

Purpose

The purpose of this paper is to evaluate the effect of fasting on blood lipid profile in fasting obese and non‐obese subjects.

Design/methodology/approach

Male and female subjects from the International Islamic University, Malaysia (IIUM), Kuantan Campus were assessed for body compositional changes during Ramadan fasting. In total, 25 males and females volunteered to participate in this study in the holy month of Ramadan. The mean age of the volunteers was 26.5±5.86 years and the age range was 21‐45 years. The age, weight and height of the volunteers were recorded on day 1 of Ramadan and weight was also recorded on day 21. The volunteers were asked for donation of blood samples on days 1, 7, 14 and 21 of the Ramadan. The blood serum was separated and stored at −20°C immediately after each collection. The serum samples stored at −20°C were analyzed for serum glucose and lipid profile. The analysis of serum lipid profile was performed with the help of clinical kits from Bayer Health Care using Bayer Express Plus Clinical analyzer. The serum was used for the estimation of total cholesterol (TC), HDL‐cholesterol (HDL‐c) and triglycerides (TG) concentrations using kit reagents from M/s Bayer Diagnostics, whereas low density lipoprotein cholesterol (LDL‐c) was determined by calculation. The statistics were performed using MINITAB statistical software (release 8.2).

Findings

The serum triglyceride concentration was significantly reduced and the reduction was 17.48 percent from day 1‐21. The serum TC concentration also reduced from day 1‐21 and the reduction was 15.93 percent. The serum LDL‐c concentration also significantly reduced from day 1‐21 and the reduction was 21.67 percent. The serum HDL‐c concentration decreased in the first weak and second week but an improving trend was observed on day 21 of the Ramadan.

Research limitations/implications

This study was not a controlled one and was conducted on free‐living individuals and therefore there is need to have controlled or adjusted physical activities studies in fasting individuals. It is always difficult to conduct experiment on human beings in the metabolic area. Furthermore, in this study it was not possible since it was a religious fasting. Another limitation is that the size of the sample was smaller than is advisable for this kind of study. However, the results were confirmed in the following month of Ramadan, as described in the paper.

Originality/value

The paper takes into consideration the effect of Ramadan fasting on blood lipid profile, which has ever been studied in obese individuals.

Abstract

Purpose

The purpose of this paper is to evaluate the effect of fasting on anthropometry and body composition in fasting obese and non‐obese subjects.

Design/methodology/approach

In total, 25 volunteers (male and female) were recruited during Ramadan. Age, sex, weight, height, waist and hip circumference and menstrual cycle status (in case of females) were recorded on day 1, and on day 21 weight and waist and hip circumference were also recorded. Similarly, bioelectrical impedance analysis (BIA) was performed on days 1 and 21 for the assessment of changes in body composition. From weight and height, basal metabolic Index (BMI) was determined. Waist‐hip ratio was determined from the waist and hip circumferences.

Findings

Weight was significantly (p<0.001) reduced in obese individuals on day 21 and accompanied by significant (p<0.01) reduction in waist hip ratios. BIA showed no significant change in the intra or extra cellular water. However, there has been shift of water between the two compartments and there was a strong positive correlation (r=0.9) between the fat free mass and total body water and negative association (r=−0.9) with total body water.

Originality/value

This study indicates that fasting could be a useful tool for the management of body weight without having a major shift in the body composition.

Abstract

Since 2007, the cloud computing term had been introduced to the information technology (IT) dictionary. The theme is attracting growing interest from both the IT world and the business players, who need to enhance information systems agility, reduced costs, or even less dependence on internal IT teams when they are judged too slow. However, the fact that cloud computing, as presented by providers, increases the agility, is unclear. Business Managers; IT professional, and academics are querying about relationship between cloud computing and IT agility. This chapter aims to answer two major concerns: Factors that influence cloud computing adoption in medium and large organizations, and the cloud computing role to improve the agility of information systems. This chapter argues that cloud computing impacts Information System (IS) performance by organizational capabilities (agility). One of the primary motivations of this chapter is the lack of fieldwork when considering how cloud computing improves the information systems’ agility.

Abstract

Purpose

Drawing on job demands-resources (JD-R) theory, this study aims to develop a model of how work engagement mediates the relationship between supervisor support and affective commitment, with religiosity moderating the relationship between supervisor support and work engagement. This study further tests a moderated-mediation model exploring the relationships between supervisor support, religiosity, work engagement and affective commitment within a unique institutional context where religious values and beliefs significantly influence and shape people management practices.

Design/methodology/approach

Using a survey-based approach, data were collected from 367 employees from the telecommunication sector in the context of Jordan.

Findings

Supervisor support was positively related to work engagement, which positively impacts affective commitment. Work engagement mediated the relationship between supervisor support and affective commitment. In addition, religiosity amplified the relationship between supervisor support and work engagement, and the mediating effect of work engagement on the relationship between supervisor support and affective commitment.

Originality/value

This study contributes to JD-R theory and pertinent literature by examining the moderating role of religiosity, an important yet neglected personal resource. To the best of the authors’ knowledge, this study is the first to examine the interaction effect between religiosity and supervisor support in predicting work engagement. It is also the first to examine a moderated mediation model exploring the relationships between supervisor support, religiosity, work engagement and affective commitment.

Abstract

Purpose

The purpose of this paper is to attempt to verify the quality of the survey instrument of office investors in rationalising green office building investment in the city of Kuala Lumpur using the Rasch measurement method. It investigates whether the quality of the data obtained from the survey is statistically acceptable and aims to ensure that the scales used are based on the same measurement model and fit with the Rasch model.

Design/methodology/approach

In achieving this objective, a questionnaire survey was developed consisting of six sections. Some 394 questionnaires were distributed, and in total, 106 responses were received from office investors who own and lease office buildings in the Federal Territory of Kuala Lumpur. The data obtained from this survey were entered into Rasch software, and the analysis aims to consider three main parameters, specifically: point measure correlation 0.32 < x < 0.8; outfit mean squared 0.5 < y < 1.5; and outfit z-standard −2 < z < 2. It also provides a separable or independent measurement instrument for the parameters of the research object.

Findings

The analysis performed using the Rasch model confirmed that all items in the questionnaire construct were statistically reliable and valid. The Rasch analysis consists of, namely, the summary statistics; item unidimensionality to provide interval measures of item endorsements and fit statistics on persons involved; and items for further investigation. Unidimensionality, as a pre-requisite to the Rasch analysis, provides statistics on whether the items are on the same latent variable intended by the instrument. The results were also supported by Cronbach’s alpha at 0.91 which showed excellent reliability for person data. The results showed that the summary statistics, unidimensionality and item fit analysis were excellent.

Originality/value

This paper introduces the application of the Rasch analysis as a provision for a new dimension and technique in examining data reliability and validity of the instrument.

Abstract

Learning outcomes

Expected learning objectives students will be able to examine the possible reasons for a company’s poor performance using relevant business tools. Students will be able to critically assess the role of technology and social media in the gem and jewellery industry in Dubai. Students will be able to analyse the customer segmentation approach used by five diamonds and to critically analyse its advantages and disadvantages. Students will be able to use the SWOT framework to identify the key weaknesses of and threats to five diamonds and identify the strengths and opportunities that the company needed to capitalize on, to be more competitive in the industry and generate high profitability. Students will be able to critically analyse the fit between the firm’s current business strategy and its business environment and develop a “turnaround” strategy.

Case overview/synopsis

Five diamonds were a trading company that dealt in gems and jewellery, natural pearls and branded watches. The company had been founded by Mustafa Al Fardan in 2003 and was currently run by his son Mohammed Al Fardan who held the position of General Manager. The company was based in Dubai, United Arab Emirates (UAE) with two local branches and eight international branches in China, France, India, Switzerland, Hong Kong and the UK. The branches were located in Palm Strip Jumeirah and in the Jumeirah Al Naseem Hotel, in the Umm Sequim area. The Palm Strip Jumeirah region is one of the largest and crowded areas in Dubai with world-class facilities such as hotels, clinics, restaurants, beaches and clubs, making it a perfect location for tourists. The Umm Sequim region is in the same area where the iconic seven-star hotel, Burj Al Arab, is located. The place is also a “must be” place for tourists and has recorded a significant increase in traffic at different times of the year. Despite their strong presence locally and internationally, the firm was facing fierce competition from the hostile business environment. Industry trends and the business environment were changing the local and global gems and jewellery industry landscape. These changes had offset five diamonds’ business strategy and its long-held business tradition. As a result, the company yearly profit had started to plummet. The company needed to revise its existing business strategy and the way it operated in the market. Failure to do so would have resulted in the firm missing the huge growth opportunity and also put itself into jeopardy.
