The Proactive-Personality with Curiosity Effects on the Innovative Work Behavior mediated by Work Engagement

There is an abundance of research that supports the relationship between proactive personality and work engagement and between work engagement and innovative work behaviors. However, there has been no study that examined work engagement as a mediator of the relationship between proactive personality and innovative work behaviors. Similarly, there has been no study that examined work engagement as a mediator between the personality traits of curiosity and exploration, with innovative work behaviors This research examines among other things, the compatibility between proactive personalities of employees, with transformational leadership behaviors of their superiors i.e. the superior-subordinate fit. It also examines the personality trait of openness to experience as a moderator affecting the dependent variable of innovative work behaviors. This study also investigates the possible moderating effect of transformational leadership on the relationship between proactive personality and work engagement. It is hypothesized that when proactive people have superiors that exhibit transformational leadership behaviors, they become even more engaged in their work. Similarly, employees with personality characteristics of curiosity and exploration, become more engaged when they are working under superiors who practice more transformational leadership behaviors, compared with employees whose superiors exhibit less transformational leadership behaviors. It is finally hypothesized that openness to experience will positively moderate the relationship between work engagement and innovative work behaviors such that people who are more open to experience will exhibit more innovative work behaviors when engaged At this stage, this represents a conceptual paper. A full quantitative study will be undertaken which will include instruments in the form of self-administered questionnaires distributed among employees involved in the aviation industry in the UAE.

Security management for services that are integrated across enterprise boundaries

This thesis addresses the problem of security management for services that are integrated across enterprise boundaries, as typically found in multi-agency environments. We consider the multi-agency environment as a collaboration network. The Electronic Health Record is a good example of an application in the multi-agency service environment, as there are different authorities claiming rights to access the personal and medical data of a patient. In this thesis we use the Electronic Health Record as the main context. Policies are determined by security goals, goals in turn are determined by regulations and laws. In general goals can be subtle and difficult to formalise, especially across admin boundaries as with the Electronic Health Record. Security problems may result when designers attempt to apply general principles to cases that have subtleties in the full detail. It is vital to understand such subtleties if a robust solution is to be achieved Existing solutions are limited in that they tend only to deal with pre- determined goals and fail to address situations in which the goals need to be negotiated. The task-based approach seems well suited to addressing this. This work is structured in five parts. In the first part we review current declarations, legislation and regulations to bring together a global, European and national perspective for security in health services and we identify requirements. In the second part we investigate a proposed solution for security in the Health Service by examining the BMA (British Medical Association) model. The third part is a development of a novel task-based CTCP ICTRP model based on two linked protocols. The Collaboration Task Creation Protocol (CTCP) establishes a framework for handling a request for information and the Collaboration Task Runtime Protocol (CTRP) runs the request under the supervision of CTCP. In the fourth part we validate the model against the Data Protection Act and the Caldicott Principles and review for technical completeness and satisfaction of software engineering principles. Finally in the fifth part we apply the model to two case studies in the multi- agency environment a simple one (Dynamic Coalition) for illustration purposes and a more complex one (Electronic Health Record) for evaluating the model's coverage, neutrality and focus, and exception handling.EThOS - Electronic Theses Online ServiceArabian Gulf Oil Co.GBUnited Kingdo

Simultaneous determination of levonorgestrel and ethinyl estradiol in combined dosage form utilizing spectrophotometric methods and high performance thin layer chromatographic method on nanosilica gel plates

Simultaneous quantification of levonorgestrel (LEV) and ethinyl estradiol (EE) was performed utilizing five different spectrophotometric methods and a high performance thin layer chromatographic method (HPTLC). The applied spectrophotometric methods were based on either ratio spectra namely; ratio difference, ratio subtraction and derivative ratio or the presence of isosbestic point specifically; absorbance subtraction and amplitude modulation. The proposed methods had the ability to resolve the overlapped spectra of the drugs with a linear relationship in the concentration range 1-65 µg/mL and 1-95 µg/mL for LEV and EE, respectively. The developed HPTLC method has revealed a good separation of the drugs upon utilizing Nano Silica Gel on TLC plates with fluorescent indicator 254 nm glass plates as the stationary phase and chloroform: methanol (99:1, v:v) as the mobile phase. The proposed HPTLC method has shown high sensitivity, where the linearity range was 0.02-3.00 µg/band and 0.5-20.0 µg/band, for LEV and EE, respectively. The proposed methods were successfully applied for the analysis of laboratory prepared mixtures as well as combined dosage form. Validation for all methods was conducted in compliance with the ICH guidelines proving the methods to be selective, linear, precise and accurate. The proposed methods were statistically compared with the pharmacopoeial method, where the obtained results showed no significant difference regarding accuracy and precision

Modeling and Analysis of Cellular Networks Using Stochastic Geometry: A Tutorial

This paper presents a tutorial on stochastic geometry (SG)-based analysis for cellular networks. This tutorial is distinguished by its depth with respect to wireless communication details and its focus on cellular networks. This paper starts by modeling and analyzing the baseband interference in a baseline single-tier downlink cellular network with single antenna base stations and universal frequency reuse. Then, it characterizes signal-to-interference-plus-noise-ratio and its related performance metrics. In particular, a unified approach to conduct error probability, outage probability, and transmission rate analysis is presented. Although the main focus of this paper is on cellular networks, the presented unified approach applies for other types of wireless networks that impose interference protection around receivers. This paper then extends the unified approach to capture cellular network characteristics (e.g., frequency reuse, multiple antenna, power control, etc.). It also presents numerical examples associated with demonstrations and discussions. To this end, this paper highlights the state-of-the-art research and points out future research directions

Pyro-oil and wax recovery from reclaimed plastic waste in a continuous Auger pyrolysis reactor

The increasing global waste plastic pollution is urging people to take immediate actions on effective plastic recycling and processing. In this work, we report the results of processing reclaimed plastic wastes from unsanitary landfill site in Kuwait by using a bench scale continuous auger pyrolysis system. The plastic feedstock was characterised. After a simple thermal densification process, the material was fed to the pyrolysis system at 500 ◦C. The pyro-oil and wax products were collected and characterised. The process mass balance was developed on dry basis, and the yields of pyro-oil, light wax, heavy wax and gases were 5.5, 23.8, 69.4 and 1.3 wt%, respectively. The findings have indicated that the reclamation of plastic waste from landfill was feasible in terms of the product distribution and characteristics. Further liquid analysis confirmed that the liquid products contained fractions that are comparable to petrol and diesel fuels. The wax products are viable and have potential application as coating, covering and lubrication

INVESTIGATION OF THE EFFECT OF TEMPERATURE AND TIME OF CASE HARDENING ON THE MECHANICAL PROPERTIES AND MICROSTRUCTURE OF LOW CARBON STEEL (AISI 1020)

The main objective of this paper is experimental study of pack carburizing of carbon steels (AISI 1020) by using two parameters (holding time and carburizing temperature). This study was conducted by using electrical furnace. This process is carried out at temperatures of 950°C for durations time 90 minutes. From the experiment, the surface hardness and thickness of carbon layer was different according to the parameters used. The quenching medium that uses in this experiment is water, oil, sea water and air. For carburizing temperature at 950°C, the highest of surface hardness value for air is 128 HV that carburized for 90 minutes, the highest of surface hardness value for water is 224 HV that carburized for 90 minutes. For carburizing temperature of 950°C, the highest of surface hardness value for sea water is 166.9 HV that carburized for 90 minutes and for carburizing temperature at 950°C which is the highest of surface hardness value for oil is 126 HV. The thickness of carbon layer was between 40μm to 120μm. The result indicates the carburizing process accelerates the diffusion of carbon atoms into the surface, thus increasing the thickness of carburized layer as well as the surface hardness

The surface finish quality is one of the most specified requirements in the machining process. To obtain the optimal surface finish, the Taguchi method used for optimization of the turning experiments based on a full factorial design, to determine three different parameters and levels by using orthogonal arrays, 9 experiments were obtained. Choice of three parameters (feed rate, cutting speed and depth of cut) were important, the cutting parameters were selected as follow: Feed rate (0.075, 0.100, 0.125mm), cutting speed (166.24, 180.70, 197.32 mm/min), depth of cut (0.5, 0.75, 1.0 mm) these parameters were chosen according to SANDVIC Tool Manufacturing Company. The series of turning experiments were performed to measure the surface roughness. The MINITAB Statistical Software was used to calculate the signal-to-noise ratio (S/N), and analysis of the variance (ANOVA), the best optimal levels and the effect of the process parameters on surface roughness were obtained. The parameters for experiment surface roughness were the feed (0.075mm/rev), cutting speed (180.70 mm/min), depth of cut (3.0mm) and that conducted in experiment number five (5). A conformation of experiment to obtained optimal levels of process parameters was carried out in order to demonstrate the effectiveness and efficiency of the employed Taguchi method as a tool to measure surface roughness. &nbsp
