Information Security Behavioral Model: Towards Employees’ Knowledge and Attitude

Information Security has become a significant concern for today’s organizations. The internal security threats acts as the most curtail type of security threat within an organization. These internal security threats are a result of poor conduct of security behavior by the employees within an organization. If not deal properly, it may hamper the auditing of organization. Auditing plays an important role in the business environment. Before conducting auditing it is essential to examine the behavioral aspect of the employees. The objective of this paper is to take out this internal threat that acts as a security slack, out of an organization by using a well-structured approach to develop a security behavior model. To validate the proposed model a survey method is used. The survey method measures the knowledge and attitude of an individual employee towards information security to analyze the behavioral security aspect of the employee’s. Statistical Analysis of the result of survey indicates that the employees’ knowledge and his attitude towards information security derive his behavior towards achieving ultimate organizational goal and thus validates the proposed security model

Effect of TiO2 Addition in Al2O3: Phase Evolution, Densification, Microstructure And Mechanical Properties

The thesis describes the effect of TiO2 additionin alumina on phase formation, densification, microstructure and mechanical properties of the composite.The ceramic composite were prepared with Al2O3 and TiO2 powder by solid state mixing route. The Al2O3–TiO2 powders contain 3, 5, 10, 13, 20, and 40 wt% of TiO2. Mixed powders were calcined at 1200oC.Calcinedpowders were uniaxially pressed into cylindrical pellets and rectangular bars, and sintered at 1600oC. X-ray powder diffraction technique was used to study the phase evolution in calcined powder and in sintered specimen. Scanning electron microscope (SEM) was used to find out the particle size and powder morphology of clacined power and microstructure of sintered sample. Flexural strength and Vickers hardness were measured on sintered sample. Calcined powder contains only alumina and titania phase. No intermediate phase was detected. In sintered sample Al2TiO5 phase was detected and its concentration increases with increases in TiO2 content.TiO2 phase was disappeared for high amount of TiO2 (20 and 40wt% addition) addition. It was found that low concentration of TiO2 (upto 10wt %) increases the density of the composite and further increase in TiO2concentration density decreases rapidly. Presence of Al2TiO5phase restricts the grain growth of alumina phase.Flexural strength and Vickers hardness of Al2O3-TiO2-Al2TiO5 composite is dependent on the content of TiO2 and the presence of Al2TiO5 phase

In government schools where is the room to write?

This article deals with writing, more specifically English writing, with regard to students studying in government schools. In these schools, classroom instruction is geared towards preparing students to write for the defining school leaving exam conducted by the Central Board of Secondary Education (CBSE) at the end of class XII. The overly centralized system does not give teachers much room to teach students about the diverse meaning writing can have in their lives. Since examinations favour strict adherence to the text with an over emphasis on accuracy, this does not encourage students to connect their writing with their lived experiences. The world of academic English found in school does not accommodate the variety of English that is found in the out-of-school contexts of government school students. In fact, teachers themselves see their writing lives as being quite separate from their role as teachers of writing

Binding of visual features in human perception and memory

The leit motif of this thesis is that binding of visual features is a process that begins with input of stimulation and ends with the emergence of an object in working memory so that it can be further manipulated for higher cognitive processes. The primary focus was on the binding process from 0 to 2500 ms, with stimuli defined by location, colour, and shape. The initial experiments explored the relative role of topdown and bottom-up factors. Task relevance was compared by asking participants to detect swaps in bindings of two features whilst the third was either unchanged, or made irrelevant by randomization from study to test, in a change detection task. The experiments also studied the differences among the three defining features across experiments where each feature was randomized, whilst the binding between the other two was tested. Results showed that though features were processed to different time scales, they were treated in the same way by Visual Working Memory processes. Relevant features were consolidated and irrelevant features were inhibited. Later experiments confirmed that consolidation was aided by iconic memory and the inhibitory process was primarily a post-perceptual active inhibition

Review on Concept Drift Detection Techniques

Detecting the changes and reacting on them is an interesting research topic in current era. Concept drift detection is comes under data stream mining. Process which takeout information from data stream which continuously generated called data stream mining. Normally in data set the data is stationary but problem arises when data is continuously generated that is data stream. So in that case the detection of concept drift is an important task. There are various techniques for drift detection. This paper focuses on some main technique of drift detection

Review of akaar

As a language teacher I have often lamented about students not being able to write. I have also bemoaned my fate of having to deal with students who do not want to write. I wondered whether it was from a lack of ability or the absence of motivation on the part of my students that I was condemned to read totally dull, boring and uninspiring texts when fulfilling my obligations of “correcting” their written work. I never thought it could have anything to do with the pedagogical practices of writing in school. Anecdotal evidence tells me that I am not alone in this. It is true that there have been a few texts that shone brightly, but they were shooting stars—precious but rar
