Enhancing Knowledge Acquisition in Pharmaceutical Organisations based in Pakistan

Absorptive Capacity (ACAP) depicts the sequential order of activities connecting externally generated knowledge into an organisation; this involves a company’s ability to acquire new knowledge from an external source, assimilate and transform it, and eventually exploit it via its industrial processes and products/services. The sandwiched role of middle managers, being interlinked between decision makers and employees, has been argued as vital to organisational success. However, their role is often viewed as having conflicts astride management i.e. between employees and decision makers. This study, using a thematic analysis approach, explores and identifies the common and conflicting role of middle managers, as viewed by different respondents in organisational hierarchies. Results, based on a sample of 33 employees operating in the Pakistan Pharmaceutical sector, indicate that conflicting roles of middle managers also persist with more common roles in organisations.

Two-Path All-pass Based Half-Band Infinite Impulse Response Decimation Filters and the Effects of Their Non-Linear Phase Response on ECG Signal Acquisition

This paper is based on the novel use of a very high fidelity decimation filter chain for Electrocardiogram (ECG) signal acquisition and data conversion. The multiplier-free and multi-stage structure of the proposed filters lower the power dissipation while minimizing the circuit area which are crucial design constraints to the wireless noninvasive wearable health monitoring products due to the scarce operational resources in their electronic implementation. The decimation ratio of the presented filter is 128, working in tandem with a 1-bit 3rd order Sigma Delta (ΣΔ) modulator which achieves 0.04 dB passband ripples and -74 dB stopband attenuation. The work reported here investigates the non-linear phase effects of the proposed decimation filters on the ECG signal by carrying out a comparative study after phase correction. It concludes that the enhanced phase linearity is not crucial for ECG acquisition and data conversion applications since the signal distortion of the acquired signal, due to phase non-linearity, is insignificant for both original and phase compensated filters. To the best of the authors’ knowledge, being free of signal distortion is essential as this might lead to misdiagnosis as stated in the state of the art. This article demonstrates that with their minimal power consumption and minimal signal distortion features, the proposed decimation filters can effectively be employed in biosignal data processing units.
