Effects of television advertising on children: with special reference to pakistani urban children

The purpose of study is to deliberate upon the impacts of television advertising on children & to identify those critical impacts which lead to behavioral and eating disorder in children. Impacts of TV advertising were identified as unnecessary purchasing, low nutritional food and materialism. A questionnaire using five point likert scale was administered to 425 parents of children aged between 9-14 years, and studying in schools. Samples were drawn through convenience sampling approach from four cities of Pakistan namely Islamabad, Rawalpindi, Bahawalpur & Multan. Data were analyzed by using SPSS software. Pearson correlation was used to measure the relationships of the variables on one-to-one basis indicating the most correlated variable was Unnecessary Purchasing which had Pearson correlation value of 0.312 and significance value of 0.000. It was followed by a Materialism which had Pearson correlation value of 0.260 and significance value of 0.000. Then comes Low Nutritional Food being Pearson correlation value of 0.258 and significance value of 0.000. Testing of hypothesis found that television advertising increases the consumption of food that is unhealthy, having low nutritional values and high in Sugar, Fat and Salt (SFS) in children with F=30.146 & P=0.000. Subsequently, it was found that Television advertising leads to increase in unnecessary purchasing in children with F= 45.747 & P=0.000 and materialism in children with F=30.545 & P=0.000. So, it is summed up that TV advertising is affecting children by increasing their food consumption pattern, preference for low-nutrient, high in sugar, fat & salt (SFS) foods and beverages, change in attitude that is aggressive and violent in nature and inclination towards unnecessary purchasing

Coupling strength control in photonic crystal/photonic wire multiple cavity devices

Resonance splitting has been demonstrated for two coupled micro-cavities with control of the free spectral range between the resonance peaks, together with a normalised transmission level of approximately 60%. Coupled micro-cavity-based structures that were separated by two closely spaced in-line coupler sections between the two micro-cavities have also been successfully fabricated and measured. The coupling strength of the two cavities was controlled via the use of hole tapering in the middle section between the two cavities. 2D finite-difference time-domain simulation shows close agreement with the results of measurements

Hybrid iterative learning control of a flexible manipulator

This paper presents an investigation into the development of a hybrid control scheme with iterative learning for input tracking and end-point vibration suppression of a flexible manipulator system. The dynamic model of the system is derived using the finite element method. Initially, a collocated proportional-derivative (PD) controller using hub angle and hub velocity feedback is developed for control of rigid-body motion of the system. This is then extended to incorporate a non-collocated proportional-integral-derivative (PID) controller with iterative learning for control of vibration of the system. Simulation results of the response of the manipulator with the controllers are presented in the time and frequency domains. The performance of the hybrid iterative learning control scheme is assessed in terms of input tracking and level of vibration reduction in comparison to a conventionally designed PD-PID control scheme. The effectiveness of the control scheme in handling various payloads is also studied

Determination of effective diffusion coefficient of immobilized Baker's yeast invertase in various concentration of PVA-alginate matrix

Baker's yeast invertase is immobilized in PVA-alginate matrix using an improved method. PVA beads were prepared by adding calcium alginate to improve its stability, mechanical and chemical properties. Boric acid was used as the cross-linking agent and additional chemicals consisting of 10% boric acid and sodium sulphate solution was used as a treatment solution to harden the PVA-alginate beads. The determination of the effective diffusion of PVA-alginate matrix the vital step in optimizing the preparation of immobilized and water-soluble biocatalyst. In this study the two-level full factorial design was used to investigate the effect of PVA and boric acid concentrations and diffusions coefficient. Diffusion coefficient (De) is one of the factors that significantly affect the mass transport within the immobilization matrix. De value varies for each concentration of PVA and boric acid. The result concluded that both factors significantly affect the De. A maximum De value of 5.0141 x 10(-5) cm2s-1 was obtained at boric acid and PVA concentraion of 7w/v and 10.5 w/v respectively

Tapered photonic crystal microcavities embedded in photonic wire waveguides with large resonance quality-factor and high transmission

We present the design, fabrication, and characterization of a microcavity that exhibits simultaneously high transmission and large resonance quality-factor (Q-factor). This microcavity is formed by a single-row photonic crystal (PhC) embedded in a 500-nm-wide photonic wire waveguide - and is based on silicon-on-insulator. A normalized transmission of 85%, together with a Q-factor of 18 500, have been achieved experimentally through the use of carefully designed tapering on both sides of each of the hole-type PhC mirrors that form the microcavity. We have also demonstrated reasonably accurate control of the cavity resonance frequency. Simulation of the device using a three-dimensional finite-difference time-domain approach shows good agreement with the experimental results

Significant of teritorry to increase sense of place in behavioural settlements

Cities have transformed collecting public places into private spaces. While in the past, public places as an urban place had a specific identity for themselves. Nowadays in nonexistence of connection between public and private life residents are forced to create their social life within their own control and are not entered to identity in public space. Urban spaces are made regardless to social needs of residents and their cultural origins. Formation of urban spaces impact to quality of its social and spatial and cannot be absorbed potential of environmental and social. For reproduction of social identity is required the behaviour-milieu this behaviour-milieu is a place for standing of pattern behaviour. In this way the role of neighborhood center as behavioural setting appears to be helping as to establish the distinctive identity of the place and create the conditions in which residents can develop their relationships and control. Behavioural complex also provide context of social partnership. Places can be considered as a physical form with their spatial territory which supports activity, ceremonies, and events and helps to sense of place formation. Feeling of neighborhood territory will exacerbate dependence and sense of place to it. The most important aspect of sense of place is attachment of people to their home or neighborhood sphere. Belonging to them make a territory feeling. Sense of place supports the cultural concept, social and culture relationship of society in the place and achieves to individual identity. This paper reviews recent research and literature review into the concept of sense of place and their assessment. The aim of this study was to evaluate the sense of place in the traditional urban to be carried out in the contemporary urban setting. The discussion presents the relationship between four groups of sense of place, territory, dependence, and finally provides a conceptual model as to show how these factors affect to sense of place. The result of this study indicates a model that mentions a relationship between dimensions of sense of place. This paper argues that territory in behavioural setting as the subset of place dependence is the best instrument to improve the sense of plac
