Knowledge management for effective research collaboration activities within Universities in Zimbabwe
( Kudzanai Charlton Chiy Anike ) 한국정책학회 2015 한국정책학회 동계학술발표논문집 Vol.2015 No.-
Science and technology universities in Zimbabwe need to be cognizant of the impact of Knowledge management for them to be recognized as highly innovative institutions internationally. This research explored the impact of knowledge management enablers (i.e. knowledge self-efficacy, top management support, organizational culture, organizational rewards, Knowledge, knowledge management system Quality, openness in communication reciprocal benefits and trust) on knowledge sharing and the resultant effects on research collaboration by Science and Technology University lecturers. This research will assist Administrators in policy making decision on enhancing knowledge management to encourage lecturers to conduct research collaboration in Science and Technology. The reviewed literature show that knowledge management factors stimulate knowledge sharing which in turu positively influences research collaboration

Aims: Ledipasvir/sofosbuvir (LDV/SOF) with ribavirin (RBV) demonstrated high SVR rates in patients with chronic hepatitis C (HCV) genotype (GT) 1 or 4 infection who have decompensated cirrhosis or who have undergone liver transplantation. Here we evaluated the effect of baseline HCV NS5A and NS5B resistance-associated variants (RAVs) on treatment outcome and characterized the viral resistance in all virologic failures. Methods: Deep sequencing with a 1% assay cut-off was performed for NS5A and NS5B at baseline for all the patients and at the time of virologic failure for those who relapsed. Results: Out of 625, 622, and 619 samples were analyzed for baseline NS5A and NS5B respectively. Table 1 summarizes SVR12 rates by treatment duration and the presence or absence of baseline NS5A RAVs. NS5B RAVs at baseline were uncommon, occurring in 4.8% (28/586) GT1 patients and 3.2% (1/31) GT 4 patients. Of these 29 patients, only one GT1 patient with CPT C cirrhosis who had L159F at baseline and was treated for 24 weeks with LDV/SOF+RBV did not achieve SVR12. NS5A RAVs at positions 24, 28, 30, 31, 58, and 93 were enriched or emerged in 20/22 (91%) GT1 and 1/3 GT4 infected patients with virologic failure. The NS5B NI RAV E237G emerged in 3 GT1a patients and 1 GT4d patient at the time of relapse (4/23, 17%). Conclusions: The presence of baseline NS5A or NS5B RAVs did not impact the treatment outcome to 12 or 24 weeks of LDV/SOF+RBV in GT1 or GT4 HCV patients with liver ransplantation without decompensated liver disease, or 24 weeks of LDV/SOF+RBV in patients with decompensated cirrhosis. Lower SVR rates were observed among the limited number of patients with decompensated cirrhosis and baseline NS5A RAVs who received 12 weeks of LDV/SOF+RBV treatment.

Intellectual property (IF) is essential to standards development although countervailing interests among stakeholders can sometimes undermine trust and inhibit progress. A consequence of slow or non-existent standards development is the loss of potential markets that can emerge only with an internationally recognized standard. Standards developing organizations (SDOs) can enable new markets by ensuring fairness and trust in their venues. The IEEE Standards Association (IEEE-SA) is an SDO that has defined specific steps to facilitate this outcome by means of its internationally recognized patent policy. This paper will describe the underlying principles that guided the creation of IEEE-SA' s policy; highlight five of the major elements of the policy; and suggest a process for integrating IF into standards so that IF stakeholders, in conjunction with standards developers, might agree to meet certain expectations in order for the standards-making process is to be successful and encourage market development.

The potential of a scale to measure relationship authenticity in marketing is explored. A measure of this type is argued to be particular valuable when brands have a difficult time in partnering with charitable organizations. An exploratory study and a pilot study suggest that there is potential for development of a full scale.
MULTI-SIGHTLINE OBSERVATION OF NARROW ABSORPTION LINES IN LENSED QUASAR SDSS J1029+2623

<P>We exploit the widely separated images of the lensed quasar SDSS J1029+2623 (z(em) = 2.197, theta = 22.'' 5) to observe its outflowing wind through two different sightlines. We present an analysis of three observations, including two with the Subaru telescope in 2010 February and 2014 April, separated by four years, and one with the Very Large Telescope, separated from the second Subaru observation by similar to 2 months. We detect 66 narrow absorption lines (NALs), of which 24 are classified as intrinsic NALs that are physically associated with the quasar based on partial coverage analysis. The velocities of intrinsic NALs appear to cluster around values of v(ej) similar to 59,000, 43,000, and 29,000 km s(-1), which is reminiscent of filamentary structures obtained by numerical simulations. There are no common intrinsic NALs at the same redshift along the two sightlines, implying that the transverse size of the NAL absorbers should be smaller than the sightline distance between two lensed images. In addition to the NALs with large ejection velocities of v(ej) > 1000 km s(-1), we also detect broader proximity absorption lines (PALs) at za(bs) similar to z(em). The PALs are likely to arise in outflowing gas at a distance of r <= 620 pc from the central black hole with an electron density of n(e) >= 8.7 x 10(3) cm(-3). These limits are based on the assumption that the variability of the lines is due to recombination. We discuss the implications of these results on the three-dimensional structure of the outflow.</P>

Radiation Portal Monitors (RPMs) are our primary border defense against nuclear smuggling, but are they still the best way to spend limited funds? The purpose of this research is to strategically compare RPM defense at the border with state-side mobile detectors. Limiting the problem to a comparison of two technologies, a decision-maker can prioritize how to best allocate resources, by reinforcing the border with stationary overt RPMs, or by investing in Mobile Radiation Detection Systems (MRDs) which are harder for an adversary to detect but may have other weaknesses. An abstract, symmetric network was studied to understand the impact of initial conditions on a network. An asymmetric network, loosely modeled on a state transportation system, is then examined for the technology that will maximally suppress the adversary's success rate. We conclude that MRDs, which have the advantage of discrete operation, outperform RPMs deployed to a border. We also conclude that MRDs maintain this strategic advantage if they operate with one-tenth the relative efficiency of their stationary counter-parts or better.

<P>Extreme variability of the winter‐ and spring‐time stratospheric polar vortex has been shown to affect extratropical tropospheric weather. Therefore, reducing stratospheric forecast error may be one way to improve the skill of tropospheric weather forecasts. In this review, the basis for this idea is examined. A range of studies of different stratospheric extreme vortex events shows that they can be skilfully forecasted beyond 5 days and into the sub‐seasonal range (0–30 days) in some cases. Separate studies show that typical errors in forecasting a stratospheric extreme vortex event can alter tropospheric forecast skill by 5–7% in the extratropics on sub‐seasonal time‐scales. Thus understanding what limits stratospheric predictability is of significant interest to operational forecasting centres. Both limitations in forecasting tropospheric planetary waves and stratospheric model biases have been shown to be important in this context.</P>

<P>The first multimodel study to estimate the predictability of a boreal sudden stratospheric warming (SSW) is performed using five NWP systems. During the 2012/13 boreal winter, anomalous upward propagating planetary wave activity was observed toward the end of December, which was followed by a rapid deceleration of the westerly circulation around 2 January 2013, and on 7 January 2013 the zonal-mean zonal wind at 608N and 10 hPa reversed to easterly. This stratospheric dynamical activity was followed by an equatorward shift of the tropospheric jet stream and by a high pressure anomaly over the North Atlantic, which resulted in severe cold conditions in the United Kingdom and northern Europe. In most of the five models, the SSW event was predicted 10 days in advance. However, only some ensemble members in most of the models predicted weakening of westerly wind when the models were initialized 15 days in advance of the SSW. Further dynamical analysis of the SSW shows that this event was characterized by the anomalous planetary wavenumber-1 amplification followed by the anomalous wavenumber-2 amplification in the stratosphere, which resulted in a split vortex occurring between 6 and 8 January 2013. The models have some success in reproducing wavenumber-1 activity when initialized 15 days in advance, but they generally failed to produce the wavenumber-2 activity during the final days of the event. Detailed analysis shows that models have reasonably good skill in forecasting tropospheric blocking features that stimulate wavenumber-2 amplification in the troposphere, but they have limited skill in reproducing wavenumber-2 amplification in the stratosphere.</P>
