Impact of Evaluation System on Organizational Performance: An Empirical Investigation on Banking Sector
Full text linkFrom the last past decade every organization is struggling for its survival and growth to have competitive edge. This study is conducted to analyze and investigate the impact of evaluation system on organizational performance. This involves discovering the relationship between evaluation system and organizational performance as now a day with the increase in organizations are focusing on managing and sustaining its performance by taking different measures. The research is conducted on banking sector and this study focuses on primary data which has been collected through questionnaire with a five point likert scale. The study used convenience sampling technique to confine the response of bankers. The data that has been collected is analyzed and assessed through statistical package for social sciences (SPSS).the results of the data has been examined through by each and every step and I have found the results. This study concluded that there is insignificant relationship between organizational performance and evaluation system that means there are many factors that help the organization to improve its performance and profitability but not the evaluation system in particular because there are less chances of factual results in different evaluation systems used by the organizations and many organizations conduct it just as a formality and afterwards and no follow-up is there regarding the evaluation system results so the organizations need to focus on purely those factors that has a significant impact on its performance and profitability and try to work on those factors for its growth and attainment of its goals. Keywords: Evaluation system, Organizational performance, performance appraisal, behaviorally anchored rating scal

All organic memory devices utilizing C60 molecules and insulating polymers
No full textThe convergence of mobile technologies combined with stricter power requirements and increasing demands have strained the current memory technology. Newer technologies such as phase changing, ferroelectric, and magnetic random access memories are unsatisfactory in meeting the new requirements. We propose a new memory technology based on our initial discovery of charge storage in C60 molecules within poly (4-vinyl phenol) (PVP). To understand the memory potential, we created single-layer devices consisting of ~30nm films of PVP+C60 sandwiched between aluminum (Al) electrodes. Current versus voltage (I-V) sweeps showed a significant hysteresis of 75nA, with distinguishable memory states. Room temperature charging of C60 was confirmed indirectly through capacitance versus voltage measurements and directly by monitoring the A1g characteristic peak of C60 during Raman measurements. We demonstrated memory operations by applying read-write-erase (RWE) pulses. The PVP+C60 devices exhibited memory retention for over 1 hour and response times of around 10ns. Characteristic hysteresis was demonstrated at the nanoscale. Conduction models were fitted at room temperature to the I-V curves. It was found that combination of direct and Fowler-Nordheim tunneling were the principle conduction mechanisms.
For a more technologically viable memory device, we developed a multi-layer device structure, consisting of a polystyrene (PS) capping layer. The resulting asymmetrical I-V curve exhibited a hysteresis ratio of 103. RWE cycles were measured with clearly distinguishable states. The memory retentions were measured over 2 hours and the response time around 10ns. The stability of the multi-layer devices was improved. I-V measurements at temperatures varying from 4.2 K to 298 K were performed to construct a theoretical model. The I-V curves were found to be temperature independent and exhibited similar tunneling behaviors as the single-layer devices. A simple model for conduction and memory operation is proposed based on the I-V fits.
These devices exhibit the characteristics needed to satisfy the new demands for memory application and have the potential of becoming the first universal memory technology. They possess the high speed, non-volatility, thermal stability, and potentially high memory densities to make them ideal for use in laptops, iPhones, mp3 players, portable video players, GPS systems, and other mobile devices.Ph.D.Includes bibliographical references

Copyright in software
No full textThe author looks at the various legal approaches to protecting computer software in the existing legal environment in New Zealand. The author argues that object code both is and should be protected by copyright law and that the Copyright Act, 1962 does provide protection to object form software. The author argues that depending on the circumstances, various approaches may be combined to achieve the optimal result. Usually this is a combination strategy of contract law and copyright law, where the former binds parties and the latter provides protection in the absence of any legal relationship.

Label-free electrochemical aptasensor for the detection of SARS-CoV-2 spike protein based on carbon cloth sputtered gold nanoparticles
Full text linkThe proliferation and transmission of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), or the (COVID-19) disease, has become a threat to worldwide biosecurity. Therefore, early diagnosis of COVID-19 is crucial to combat the ongoing infection spread. In this study we propose a flexible aptamer-based electrochemical sensor for the rapid, label-free detection of SARS-CoV-2 spike protein (SP). A platform made of a porous and flexible carbon cloth, coated with gold nanoparticles, to increase the conductivity and electrochemical performance of the material, was assembled with a thiol functionalized DNA aptamer via S–Au bonds, for the selective recognition of the SARS-CoV-2 SP. The various steps for the sensor preparation were followed by using scanning electron microscopy, cyclic voltammetry and differential pulse voltammetry (DPV). The proposed platform displayed good mechanical stability, revealing negligible changes on voltammetric responses to bending at various angles. Quantification of SARS-CoV-2 SP was performed by DPV and chronopotentiometry (CP), exploiting the changes of the electrical signals due the [Fe(CN)6]3-/4- redox probe, when SARS-CoV-2 SP binds to the aptamer immobilized on the electrode surface. Current density, in DPV, and square root of the transition time, in CP, varied linearly with the log[ SARS-CoV-2 SP], providing lower limits of detection (LOD) of 0.11 ng/mL and 37.8 ng/mL, respectively. The sensor displayed good selectivity, repeatability, and was tested in diluted human saliva, spiked with different SARS-CoV-2 SP concentrations, providing LODs of 0.167 ng/mL and 46.2 ng/mL for DPV and CP, respectively
