Foreign Aid-Blessing or Curse: Evidence from Pakistan
No full textThe role of foreign aid in promoting economic growth is a debatable issue and remains unsettled at both theoretical and empirical levels. Pakistan has received a substantial amount of foreign aid since its Independence in 1947 but little improvement has been observed in its socio-economic development. This study considers the question as to whether foreign aid is a blessing or a curse for Pakistan. The empirical analysis is based on the ARDL cointegration approach. We examine the aid-growth link at the aggregate and disaggregate levels for the period 1972 2006. The results show negative and insignificant effects of foreign aid on the growth at the aggregate as well at the disaggregate level. The findings further suggest that domestic investment, export growth, and inflows of foreign direct investment are important contributors in enhancing economic growth in Pakistan.Foreign Aid, Economic Growth, FDI, Cointegration
Application of through-vial impedance spectroscopy as a novel process analytical technology for freeze drying
No full textThis study aims to validate and develop applications for a novel impedance-based process analytical technology for monitoring the attributes of the product during the entire freeze-drying process (from pre-freezing and annealing to primary and then secondary drying). This measurement approach involves the application of foil electrodes, mounted externally to a conventional glass freeze-drying vial, and coupled to a high-impedance analyser. The location of the electrodes on the outside, rather than the inside of the vial, leads to a description of the technology as a through-vial impedance spectroscopy (TV-IS) technique. The principle observation from this approach is the interfacial-polarization process arising from the composite impedance of the glass wall and product interface. For a conventional glass vial (of wall thickness ~ 1 mm and cross sectional diameter ~ 22 mm) it was shown that the process is manifest within the frequency range 101 to 106 Hz, as a single, broad band peak which spans 2-3 decades of the imaginary part spectrum. Features of the interfacial-relaxation process, characterised by the peak amplitude, C″Peak, and peak frequency, fpeak, of the imaginary capacitance spectra and the equivalent circuit elements that model the impedance spectra (i.e. the solution resistance (R) and solution capacitance (C) were monitored along with the product temperature data during the cycle(s), for a variety of surrogate formulations comprising lactose, sucrose, mannitol or maltodextrin solutions, during the freezing, re-heating, annealing and primary drying stages of freeze drying.
It was shown that the parameters, fpeak and R, are strongly coupled to each other and change as a function of the temperature of the solution and its phase state, whereas C″Peak is strongly coupled to the amount of ice that remains during the drying process. Both log fpeak and log R have a linear dependence on the temperature of the solution, provided there was no phase change in the solution. The crystallization process (ice onset, solidification and equilibration to shelf temperature) is characterized well by both log fpeak and log R, whereas the parameter R demonstrates most clearly the formation of eutectic crystallization during freezing. In contrast it was the parameter C which was most sensitive to the detection of the glass transition during re-heating. During primary drying, it was shown that C″peak, is dependent on the amount of ice remaining and therefore provides a convenient assessment of the rate of drying and primary drying end point.
The impedance changes during annealing provide a mechanistic basis for the modifications in ice structure which result directly in the observed decrease in primary drying times. The principal observation on annealing of a 10% w/v solution of maltodextrin, was the minimal changes in the glass transition (recorded at ~−16 °C) during the re-heating and cooling step (post-annealing). This result alone appears to indicate that a maximum freeze concentration was achieved during first freezing with no further ice being formed on annealing. The phenomenon of devitrification (and the production of more ice, and hence larger ice crystals) was therefore discounted as the mechanism by which annealing impacts the drying time. Having excluded devitrification from the mechanism of annealing enhanced drying, it was then possible to conclude that the decrease in the electrical resistance (that was observed during the annealing hold time) must necessarily result from the simplified structure of the unfrozen fraction and the improved connectivity of ice crystals that may be the consequence of Ostwald ripening.
The application of through vial impedance measurement approach provides a non-invasive, real time monitoring of critical process parameters which subsequently leads to an improved understanding of the mechanisms and effects of different parameters, providing a reliable basis for process optimization, along with improved risk management to ensure optimum quality of the formulation and optimization of the freeze drying process

Reason: Author requested closed access (OA after 2yrs) in Vireo ETD systemDespite the importance of work environment support for training variables (training opportunities, supervisory support for training, peer support for training and opportunity to use training), there is limited understanding of how these variables influence employees' organizational commitment. This study aims to explore the relationship between work environment support for training and employees' organizational commitment in Pakistan’s banking sector. Social Exchange Theory (SET) was utilized as a framework where work environment support for training is considered as a favor from organization and organizational commitment was considered as a reciprocal attitude of employees. The study also explored whether training transfer mediates a relationship between work environment support for training and organizational commitment. Furthermore, the study explored whether the trainees’ characteristics such as training self-efficacy, training motivation, perceived utility of training, and training retention moderates the relationship between work environment support for training and organizational commitment. An online survey based on validated instruments used to collect data from the employees (n=334) working in one of the largest banks of Pakistan. Multiple regression analysis, among other statistical techniques, was used to test the hypotheses and determine significant relationships. The results showed that banking employees in Pakistan were not found to experience affective commitment; that is, no significant relationship was found between work environment support for training variables and affective commitment. Rather, the study found a positive relationship between (i) training opportunities and continuance commitment, (ii) opportunity to use training and continuance commitment, and (iii) supervisory support for training and normative commitment. All four trainee characteristic—e.g., training self-efficacy, training motivation, perceived utility of training and training retention—were found to moderate the relationship between training opportunities and continuance commitment. Training motivation also moderated the relationship between peer support for training and normative commitment. Several implications of these findings, limitations, and future research suggestions are discussed.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2021-05-01Embargo set by: Seth Robbins for item 112299

Comparative Efficacy of Synthetic Resins on Various Woods against Subterranean Termites
No full textThe present studies were carried out to determine efficacy of synthetic resins on woods of three tree species to ward off subterranean termites. Three resins types in three concentrations were applied by brushing and dipping on wooden stakes which were exposed to termites' for a period of 4 weeks in the field. Weight loss before and after resin treatment was indicative of effectiveness. Highest concentration of all resins significantly reduced the chances of termites' infestation as compared to other concentrations by dipping application in contrast to coating method. Drying of woods prior to resin application was also effective in resisting termites' infestation. The findings of treatment with resins are discussed with previously cited effects of resins and its implication in wood preservation. Copyright 2017 Zoological Society of Pakistan
