HAYATI Journal of Biosciences , 2012,
Abstract: This study evaluated the effect of biofloc technology (BFT) application on water quality and production performance of red tilapia Oreochromis sp. at different stocking densities. Three different fish densities were applied, i.e. 25, 50, and 100 fish/m3, and for each density there were Control (without external carbon input) and BFT treatments. Mixed sex red tilapia with an initial average body weight 77.89 + 3.71 g was cultured in 3 m3 concrete tanks for 14 weeks. Molasses was added on BFT treatments as the organic carbon source at a C/N ratio of 15. Control treatments of each density tested showed more fluctuated water quality parameters throughout the experimental period. The highest TAN and nitrite-nitrogen were observed in control treatment at a stocking density of 100 fish/m3 (3.97 mg TAN/L and 9.29 mg NO2-N/L, respectively). The highest total yield was observed in control treatment at the highest density treatment (43.50 kg), whereas the highest survival was obtained by BFT treatment at a density of 25 fish/m3 (97.78 + 0.77%). Total feed used in BFT was lower than that of control treatments in particular at 50 fish/m3 density (P < 0.05) suggesting that biofloc could be continuously harvested by the fish as other source of food.
A Review Study on Spiritual Intelligence, Adolescence and Spiritual Intelligence, Factors that May Contribute to Individual Differences in Spiritual Intelligence, and the Related Theories
Maryam hosaini,Habibah Elias,Steven Eric Krauss,Siti Aishah
International Journal of Psychological Studies , 2010, DOI: 10.5539/ijps.v2n2p179
Abstract: This paper reviewed the articles about adolescence, its relation to spiritual intelligence and the related theories. The adolescence period is the best time to develop positive emotions and training skills, because adolescents are seeking to find their identity and their future personality at this period. Spiritual intelligence has a significant influence on the quality of life and it goes without saying that adolescence is a sensitive period which requires specific training to make a brighter future and be exposed to the difficulties. Spirituality can be viewed as a form of intelligence because it predicts functioning and adaptation and offers capabilities that enable people to solve problems and attain goals. Conceiving spirituality as a sort of intelligence extends the psychologist’s conception of spirituality and allows its association with the rational cognitive processes like goal achievement and problem solving. Emotional intelligence allows us to judge in which situation we are involved and then to behave appropriately within it. Spiritual intelligence allows us to ask if we want to be in this particular situation in the first place.

International Journal of Psychological Studies , 2010, DOI: 10.5539/ijps.v2n2p90
Abstract: The main goal of this study is to determine whether SI-G training is able to help increase SQ. The present experimental study examined the effect of SI-G training on spiritual intelligence among Iranian students in Imam Khomeini School situated in Kuala Lumpur. This study has evaluated the effect of SI-G training program regarding the increasing SQ and its subscales. It evaluates the follow up test and the sustainability of the training program. The study shows that with SI-G training, spiritual intelligence and its subscales can be enhanced. Essentially, spiritual intelligence is a factor that affects training, practice and society in general. There is a relationship between most of the subscales of spiritual intelligence, therefore, training some of the subscales of spiritual intelligence can directly affect the other subscales. In this study, spiritual intelligence was measured by Integrated Spiritual Intelligence Scale (ISIS) employed to assess students’ spiritual intelligence before and after the three weeks training period. Subsequent findings were discovered following SI-G training program. The result of the pre-test showed that most of the students have low SQ and the researcher has chosen 34 of them as sample. The sample gratitude has the lowest score and run through the highest mean between other subscales. This study revealed the significant relationship between 22 subscales of spiritual intelligence and between these subscales in relation to spiritual intelligence. The findings provided that SI-G training has effect on increasing spiritual intelligence and also improved most of the subscales. After 3 weeks, the researcher conducted a follow up test, comparing its result with post test, revealed that training program did not have good sustainability on SQ and some of the subscales. However, after comparing the results with pre-test, training program showed an effect on increasing SQ within three weeks of training.

Maryam Awadh
Open Journal of Leadership (OJL) , 2018, DOI: 10.4236/ojl.2018.74015
Abstract: In the past, the leadership position primarily involved how leaders handled their role. The notion of collective leadership is significant for constructing the educational community and sustaining inclusive collective participation. This paper shows the framework of the leadership, and comprehensively addresses the ways in which leaders have a direct impact on classroom instruction and student learning outcomes. The study outlines how leadership abilities are linked to student achievement and illustrates how principals and instructional leaders are the central figures of this leadership. The study found the ways in which leaders indirectly influence student achievement through their impact on teacher motivation and work conditions, and whether teachers’ knowledge and skills have an effect on student achievement in the educational system. The influences of collective leadership on classroom instruction were examined, including ways in which changes in instruction could influence both teachers and students.

Creative Education (CE) , 2017, DOI: 10.4236/ce.2017.89097
Abstract:
To understand the enactment of Education for Sustainable Development (ESD) in higher education institution (HEI) and why very unequal ESD activity that mostly focused on campus greening rather than on pedagogic reform in HEI requires more than simply an examination of the ESD curriculum and pedagogy. To grasp why and how ESD is implemented in a HEI, the contexts in which it was created and implemented should be considered. Systems structures that include the context of the phenomena can show how the interaction between various factors gives rise to the outcomes that can be observed at the event level which is the enactment of ESD at the HEI. This paper presents a finding of the case study concerning systems structure of ESD conducted at one Malaysia university. This study is explanatory and may give insight to understand ESD enactment in HEI especially in Asian and developing country context. The findings from this study demonstrate that the agents’/ lecturer’s individual systems and the organisational/university system are co-evolving with their environment. The changes in the environment, such as the accelerating sustainability crisis and global influence, are perceived by the lecturers as stimulating ESD enactment in the university. The university’s response to the sustainability agenda involves temporality and selection. This explained the university’s delayed response to the sustainability agenda, until sustainability agenda gained attention globally after the Brundtland Report in 1987.Despite the forces to adapt to environmental changes, within a system there is resistance to change. In this study, it included: the lecturers’ perceived lack of sustainability awareness; sustainability acceptance influenced by disciplines; limited financial support from the university; a compartmentalised education system; bureaucratic tensions; and lacking of teaching skills among ESD educators.

Azizah Hamzah, Siti Ezaleila Mustafa
Advances in Journalism and Communication (AJC) , 2014, DOI: 10.4236/ajc.2014.22007
Abstract: Digital technology, also known as new media technology, has become an influential tool in this era. This technology is no longer an option anymore but it is a necessity in many fields. As one of the areas that are inextricably linked with technology, the media industry including journalism, cannot escape from being impacted upon by any technological development and changes. In this era, media organizations and journalists have to confront an important challenge which impacted them strongly in the mass media, namely the advent of Internet journalism. With that in mind, this paper will discuss the changing nature of Malaysian newsrooms and identify the digital readiness among them in accordance with the needs of the digital media era. With a questionnaire designed to determine how news organizations try to meet the latest demands from the convergence of the newsroom as well as the readiness of the journalists in facing the challenges of the new technolo-gically driven newsrooms, the findings have provided insights into the leadership styles of Malay-sian media organizations and the readiness of Malaysian journalists in facing the current technol-ogical complexities, the retraining of employees, and other skills needed in the twenty first century media organizations.
Intelligent Dynamic Aging Approaches in Web Proxy Cache Replacement  [PDF]
Waleed Ali, Siti Mariyam Shamsuddin
Journal of Intelligent Learning Systems and Applications (JILSA) , 2015, DOI: 10.4236/jilsa.2015.74011
Abstract: One of commonly used approach to enhance the Web performance is Web proxy caching technique. In Web proxy caching, Least-Frequently-Used-Dynamic-Aging (LFU-DA) is one of the common proxy cache replacement methods, which is widely used in Web proxy cache management. LFU-DA accomplishes a superior byte hit ratio compared to other Web proxy cache replacement algorithms. However, LFU-DA may suffer in hit ratio measure. Therefore, in this paper, LFU-DA is enhanced using popular supervised machine learning techniques such as a support vector machine (SVM), a naive Bayes classifier (NB) and a decision tree (C4.5). SVM, NB and C4.5 are trained from Web proxy logs files and then intelligently incorporated with LFU-DA to form Intelligent Dynamic- Aging (DA) approaches. The simulation results revealed that the proposed intelligent Dynamic- Aging approaches considerably improved the performances in terms of hit and byte hit ratio of the conventional LFU-DA on a range of real datasets.

Journal of Biomedical Science and Engineering (JBiSE) , 2009, DOI: 10.4236/jbise.2009.27077
Abstract: The aim of the present investigation was to develop a biosensor for the detection of amino acids, Leucine, Isoleucine and Valine based on a quartz crystal nanobalance. leucine (Leu), isoleucine (Ile), and valine (Val) were selectively determined by quartz crystal nanobalance (QCN) sensor in conjunction with net analyte signal (NAS)-based method called HLA/GO. An orthogonal design was applied for the formation of calibration and prediction sets including Leu, Ile and Val compounds. The selection of the optimal time range involved the calculation of the net analyte sig-nal regression plot in any considered time window for each test sample. The searching of a region with maximum linearity of NAS regression plot (minimum error indicator) and minimum of PRESS value was carried out by applying a moving window strategy. On the base of obtained results, the differences on the adsorption profiles in the time range between 1 and 300 s were used to determine mixtures of compounds by HLA/GO method. The results showed that the method was successfully applied for the determina-tion of Leu, Ile and Val.
