Abstract Aim: This study investigated the intentions, opportunities, and barriers to engaging in a meaningful internationalization of higher education in Malawi.Methods: This was cross-sectional research that was done between June and October 2021. Using a purposive (judgmental) sampling, we recruited 212 respondents from various institutions of higher education in Malawi. Multilinear regression analysis was used to analyze the factors with the P-value set at 0.05 level of statistical significance. Results: The results indicated that the majority of the respondents were males (63.7%) who fell into 30 years age bracket. Further, the results from the multilinear regression analysis indicate that Institutional collaboration (ß=0.326, p=0.000, CI=0.27—0.383), clear Policy on Mobility (ß=0.146, p=0.0.004, CI=0.047-0.246), experience (ß=0.083, p=0.117, CI=-0.021-0.186), academic rank (ß=0.114, p=0.000, CI=0.069-0.159) were positively statistically significant variables, whereas on the other hand, Occupation (ß=-0.131, p=0.002, CI=-0.213-0.49), academic qualification (ß=-0.106, p=0.013, CI=-0.19-0.023 and mobilityImportance (ß=-0.116, p=0.022, CI=-0.215-0.017) were negatively significant variables respectively.Conclusion and Recommendations: institutions need to invest in international and inter-institutional collaboration, clarify policy direction regarding academic mobility, keep track and linkages with mobile faculty, create a conducive social and formal institutional culture that attracts back mobile faculty, and reduce staff turnover.

Abstract. This study aims to dissociate the respective roles of systemic nephrosis and of the intrarenal effects of proteinuria in the pathogenesis of focal segmental glomerulosclerosis (FGS) in adriamycin nephrosis. To this purpose, this study examined proteinuria and FGS in bilateral (BAP) and unilateral proteinuria (UAP) in two different rat strains. UAP was obtained by protecting one kidney from exposure to adriamycin by temporary clipping of one renal artery during adriamycin injection. At sacrifice (week 12), FGS was present in BAP and in exposed kidneys in UAP, but not in unexposed kidneys. FGS correlated significantly with proteinuria per kidney in BAP and UAP. Remarkably, for a given proteinuria per kidney, the sclerosis score was higher in BAP than in UAP, reflected by a higher ratio of FGS score per mg proteinuria per kidney (Wistar: 0.09 ± 0.01 in BAP versus 0.05 ± 0.01%/mg protein per d in UAP, P < 0.05; Lewis: 0.12 ± 0.01 in BAP versus 0.07 ± 0.01%/mg protein per d in UAP, P < 0.05), indicating that the local damaging effects of proteinuria are modified by other factors. Cholesterol correlated with total proteinuria in BAP and UAP. FGS score was positively correlated with cholesterol. The latter correlation was similar in BAP and UAP, indicating that cholesterol was a more uniform predictor for FGS than proteinuria per kidney. This was independent of strain-specific factors. On multilinear regression analysis, cholesterol turned out to be the most consistent predictor of FGS in proteinuric kidneys, with a stronger predictive value than proteinuria per kidney. It is concluded that although systemic sequelae of nephrosis do not induce renal damage in nonproteinuric kidneys, they modify the severity of proteinuria-induced FGS in proteinuric kidneys.

Objective In this study, we evaluated factors affecting changes in cervical lordosis after deformity correction and during follow-up period in adult spinal deformity (ASD) patients with severe sagittal imbalance. Methods Seventy-nine patients, with an average age of 71.6 years, who underwent long-segment fixation from T10 to S1 with sacropelvic fixation were included. We performed a comparative analysis of the radiographic parameters after surgery (Post) and at the last follow-up (Last). We calculated the Pearson’s correlation coefficient and performed multilinear regression analysis to predict independent parameters for Post and Last cervical lordosis (CL), T1 slope (T1S), and thoracic kyphosis (TK). Results Hyperlordotic changes of -23.3° in CL before surgery was reduced to -7° after surgery, and Last CL had increased to -15.3°. T1S was reduced from 27° before surgery to 14.4° after surgery and had increased to 18.8° at the last follow-up. Through multilinear regression analysis, we found that Post CL and T1S were more significantly affected by the amount of LL correction (p = .045 and .049). The effect of Last T1S was significantly associated with the Last CL; the effect of Last TK, with the Last T1S; and the effect of Post PI-LL, with the Last TK (p < .05). Conclusion The postoperative kyphotic change in CL in ASD patients with preoperative cervical hyperlordosis is not permanent and is affected by drastic LL correction and SVA restoration. To achieve spinopelvic harmony proportional to the difference in LL relative to PI, TK becomes modified over time to increase T1S and CL, in an effort to achieve optimal spine curvature.

The Mean

All textbooks and articles dealing with classical tests in the context of linear models stress the implications of a significantly large F-ratio since it indicates that the mean square for whatever effect is being evaluated contains significantly more than just error variation. In general, though, with one minor exception, all texts and articles, to the authors' knowledge, ignore the implications of an F-ratio that is significantly smaller than one would expect due to chance alone. Why this is so difficult to explain since such an occurrence is similar to a range value falling below the lower limit on a control chart for variation or a p-value falling below the lower limit on a control chart for proportion defective. In both of those cases the small value represents an unusual and significant occurrence and, if valid, a process change that indicates an improvement. Therefore, it behooves the quality manager to determine what that change is in order to have it continue. In the case of a significantly small F-ratio some problem may be indicated that requires the designer of the experiment to identify it, and to take “corrective action.” While graphical procedures are available for helping to identify some of the possible problems that are discussed they are somewhat subjective when deciding if one is looking at an actual effect; e.g., interaction, or whether the result is merely due to random variation. A significantly small F-ratio can be used to support conclusions based on the graphical procedures by providing a level of statistical significance as well as serving as a warning flag or warning that problems may exist in the design and/or analysis.
