Leading sustainable schools in the era of Education 4.0: Identifying school leadership competencies in Malaysian secondary schools

The purpose of the study was to develop an empirical School Leadership Competency Model for the era of Education 4.0 (SLCMEduc4.0) to identify school leadership competencies that facilitate and maximize effectiveness in leading sustainable schools in Malaysia. Exploratory Factor Analysis (EFA) was employed to identify the underlying factors whereas Confirmatory Factor Analysis (CFA) was applied to test the measurement models using Structural Equation Modelling. A total of 444 and 931 respondents completed the survey with usable data for EFA and CFA respectively. The results suggested that the SLCMEdu4.0 can be explained by eight factors namely; Leading for Learning, Emotional Intelligence, Critical Thinking, Communication and Ethics, Collaboration, Decision Making and Problem Solving, Digital Dexterity and Entrepreneurial with good fit statistics; normed x2=2.628, TLI=.950, CFI=.954 and RMSEA=.042. With a total of 40 items, the model also features good convergent and discriminant validity and construct reliability. The SLCMEduc4.0 is a coherent premier model that provides useful feedback for practitioners in planning, designing and evaluating future professional development programmes for school leaders. The study encourages a fresh look at educational leadership development locally and globally specifically in enhancing the leadership development of Malaysian school leaders towards productive change in the era of Education 4.0

Distribution, prevalence and intensity of protozoan and monogenean parasites of carp fingerlings in selected nursery ponds

An experiment was carried out on the distribution, prevalence and intensity of infestation of protozoan and monogenean parasites of carp fingerlings in two selected areas of Bangladesh. Six hundred and forty fingerlings of seven species viz. Catla calla, Hypophthalmicthys molitrix, Labeo rohita, Ctenophalyngodon idella, Cyprinus carpio, Barbodes gonionotus and Cirrhinus cirrhosus from different nursery ponds of Shambhuganj, Mymensingh, and Santaher, Bogra were examined during this investigation. This study revealed that carp fingerlings carried a large number of protozoan and monogenean parasites. Different protozoan parasites viz Trichodina domerguei, Trichodina reticulata, Myxobolus koi, Chilodonella cyprini and monogenean parasites such as Dactylogyrus extensus, Dactylogyrus catlarius and Dactylogyroides tripathi were identified in the experimental fishes throughout the study period. It has been observed that distribution, prevalence and intensity of parasite in carp fingerlings are species and zone specific. In case of C. cirrhosus, the highest prevalence of protozoan parasite viz Trichodina domerguei were 93.75% and 75.92% in Santhahar and Shambhuganj area respectively. Irrespective of host, the most prevalent ectoparasite was Dactylogyrus extensus, followed by Myxobolus koi, Chilodonella cyprini and Dactylogyroides tripathi. Relatively higher mortality of carp fingerlings was found at younger stage. The highest prevalent parasitic species was identified as Trichodina domerguei followed by Trichodina reticulata and Dactylogyrus catlarius were found 93.75% in Cirrhinus cirrhosus, 68.75% in Cyprinus carpio and 39.44% in Hypophthalmicthys molitrix respectively

Renal Vein Thrombosis

ObjectiveThe aim of this article is to review the published English literature on aetiology, pathology, clinical presentation, diagnostic methods and treatment of renal vein thrombosis.Materials and methodsWe searched the published literature from Medline & Pubmed using keywords renal vein thrombosis, anti-phospholipid syndrome and nephrotic syndrome. Data was extracted from individual case reports, case series, articles on pathology, diagnostic tests, treatment modalities, and previous reviews. Case reports which did not add any new information were excluded.ResultsWe selected 60 references based on the above criteria. Renal vein thrombosis is relatively rare. CT angiography is considered the investigation of choice. Alternatives include MR angiography or renal venography in highly selected patients. As the condition is relatively uncommon, consensus on the best form of therapy for this condition has been slow to evolve. The trend in management has shifted to non-surgical therapies particularly systemic anticoagulation except in highly selected group of patients

A framework for collaborative supply chain: Level 1 - planning for redesign

In improving the competitiveness of business organisations in the 21” century, minimizing cost and increasing productivity are no longer factors that can promise success.The changes in customer trends which are focusing more on product or service customization, high quality and short delivery times are additional crucial factors that organisations should be aware of: These factors have direct impact on how the management can make a decision in utilizing the capability of its Supply Chain Management (SCM). The intention of the paper is to promote the utilization of a Knowledge-Based System (KBS) in identifying organisations current position and evaluate the business process of an existing SCM in order to shift its environment and focus to become collaborative SCM. A model for collaborative SCM is currently being developed by the authors and will be used in the next stage of the research

Evaluating the toxic effects of Ficus infectoria Roxb. and Emblica officinalis Gaertn. leaf extracts on cell division and chromosomal morphology of Cicer arietinum L.

In the present study, the aqueous extracts of Ficus infectoria and Emblica officinalis leaves were evaluated for their toxic effect on cell division and chromosomal morphology of Cicer arietinum root apical meristem. The extracts were prepared by dissolving 15 gm, 30 gm and 45 gm of dry leaf powder in 1000 ml of double distilled water. The experiment was conducted in sterilized petri dishes. The results revealed that the different concentrations of aqueous extract of F. infectoria and E. officinalis caused cytotoxic and mitodepressive effects on chromosome of Cicer arietinum. The dose–dependent and statistically significant (

Dft And X-ray Study Of Structural, Electronic, Elastic And Optical Properties In Be1–xznxs Alloys Depending On Vegard’s Law

Structural, optical and electronic properties and elastic constants of Be1–xZnxS alloys have been studied by employing the commercial code Castep based on density functional theory. The generalized gradient approximation and local density approximation were utilized as exchange correlation. Using elastic constants for compounds, bulk modulus, band gap, Fermi energy and Kramers–Kronig relations, dielectric constants and the refractive index have been found through calculations. Apart from these, X-ray measurements revealed elastic constants and Vegard’s law. It is seen that results obtained from theory and experiments are all in agreement

Flow characteristics of HFC-134a in an adiabatic helical capillary tube

Paper presented at the 5th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, South Africa, 1-4 July, 2007.In this paper, an attempt is made to model the refrigerants flow through helical adiabatic capillary tubes used in domestic refrigerators and small residential air conditioners. The present study, based on homogenous two-phase flow model, predicts the performance of the helical capillary tube under adiabatic flow conditions. The variation of different physical parameters like pressure, temperature, quality, void fraction, velocity, and entropy with the length of adiabatic capillary tube has been investigated. The effect of varying capillary tube diameter and the pitch on pressure variation along the length is carried out. The simulation results are validated with experimental findings of the previous researchers for straight capillary tube as the literature lacks experimental work on helical capillary tube. It is found that when subjected to similar conditions, the helical capillary tubes are shorter than their straight counterparts.cs201

A multifactorial obesity model developed from nationwide public health exposome data and modern computational analyses

Summary Statement of the problem Obesity is both multifactorial and multimodal, making it difficult to identify, unravel and distinguish causative and contributing factors. The lack of a clear model of aetiology hampers the design and evaluation of interventions to prevent and reduce obesity. Methods Using modern graph-theoretical algorithms, we are able to coalesce and analyse thousands of inter-dependent variables and interpret their putative relationships to obesity. Our modelling is different from traditional approaches; we make no a priori assumptions about the population, and model instead based on the actual characteristics of a population. Paracliques, noise-resistant collections of highly-correlated variables, are differentially distilled from data taken over counties associated with low versus high obesity rates. Factor analysis is then applied and a model is developed. Results and conclusions Latent variables concentrated around social deprivation, community infrastructure and climate, and especially heat stress were connected to obesity. Infrastructure, environment and community organisation differed in counties with low versus high obesity rates. Clear connections of community infrastructure with obesity in our results lead us to conclude that community level interventions are critical. This effort suggests that it might be useful to study and plan interventions around community organisation and structure, rather than just the individual, to combat the nation’s obesity epidemic
