A big size government fosters corruption, which can lead to inefficiencies and resource costs that impede economic progress. In this chapter, it is argued that much of the previous studies have focused only on detecting the linear effects of corruption on growth. This study, therefore adopts the Threshold Autoregression (TAR) approach by using an annual panel data of 100 countries during 1990-2012 to evaluate any existence of a non-linear relationship. This study presents evidence that suggests the existence of a hump shaped (nonlinear) relationship between corruption and long-run economic growth. When the government size is small (11.518%), corruption positively affects economic growth. Whereas, when the government final consumption expenditure (% of GDP) is larger than 19.027%, corruption negatively affects economic growth. Furthermore, the result indicates that a non-linear relationship of the ‘Armey curve' exists in our panel of countries. Thus, a government should investigate whether government size is over-expanding or not when designing its public finance policy.

OBJECTIVE: Postoperative hyperglycemia has been shown to be associated with higher morbidity and mortality in pediatric patients. Data on risk factors for neonatal patients is limited. The objective of this study was to identify pre- and intraoperative risk factors associated with postoperative glucose in neonates. METHODS: We conducted a retrospective cohort study of neonates after surgical procedures between January and December 2016 in a quaternary neonatal intensive care unit. The primary outcome was hyperglycemia defined as serum glucose ≥8.3 mmol/L during the first 4 hours postoperatively. Secondary outcomes included death and length of stay. We assessed the association of risk factors with the postoperative glucose. RESULTS: In total, 206 surgical procedures (171 patients) were evaluated, among which 178 had serum glucose values during the first 4 hours postoperatively available. The incidence of hyperglycemia was 54% (n = 95). The median (IQR) glucose during the first 4 hours in NICU was 8.4 (6.52–10.65) mmol/L. Risk factors for postoperative hyperglycemia were intraoperative glucose infusion rate (GIR) and gestational age. There was a non-linear relationship between gestational age and postoperative hyperglycemia. Mortality occurred in 6 (7%) in the no-hyperglycemia group and 3 (3%) in the hyperglycemia group (p = 0.31). CONCLUSIONS: Among the risk factors, intraoperative GIR was identified as a modifiable factor that can reduce postoperative hyperglycemia. A non-linear relationship of gestational age with postoperative glucose provides new insights that may help advance our understanding of the complex mechanisms of glucose homeostasis in neonates.

Purpose This study aims to examine the significance of the non-linear relationship of board size and board independence on the financial performance of listed non-financial firms in India. Design/methodology/approach The study draws the sample of the listed non-financial firm in the Indian market from the year 2011–2018 and applied panel least squares regression with and without industry fixed effects on the model with quadratic equation. Quantile regression is also used to test the robustness of the results. The financial performance is measured through one accounting measure (i.e. return on assets [ROA]) and one market-based measure (i.e. Tobin’s Q). The empirical model also controls firm-specific variables which are expected to have an impact on financial performance. Findings The study found that the relationship of board size and board independence with the financial performance of a firm is in a non-linear inverted U-shape. The results are qualitatively similar for both ROA and Tobin’s Q after controlling industry fixed effects. Originality/value This is the first study in India which tests the non-linear relationship of board size and board independence with the financial performance of the firm. The study contributes to the limited literature on the implications of board characteristics on the performance of the firms in India.

This study aims to examine the impact of foreign ownership on the performance of Indian firms. Additionally, it also analyses the non-linear relationship of foreign ownership with firm performance. A panel data approach has been used in this study. Specifically, the fixed effect estimation technique is used to examine the relationship between foreign ownership and firm performance during the period 2009–2010 to 2018–2019. The foreign institutional shareholders and the foreign corporate bodies hold more shareholding than the foreign individual investors. The authors find that foreign institutional investors and foreign corporate bodies bear a positive relationship with the performance of Indian firms. Additionally, foreign ownership shows a non-linear relationship with firm performance. The results are robust across the various proxies of firm performance, and sub-samples based on foreign ownership

1. The decrease in the protein fluorescence (F) of Neurospora crassa glutamate dehydrogenase is linearly related to the increase in the fraction of the coenzyme sites occupied by NADPH (α) at pH6.35. Under these conditions NADPH causes this enzyme to dissociate to monomers. 2. There is a non-linear relationship of F to α for NADH binding to give the alcohol dehydrogenase–NADH–isobutyramide complex, the l-glycerol 3-phosphate dehydrogenase–NADH complex and the bovine glutamate dehydrogenase–NADH–glutamate complex. The non-linearity is accurately represented by F=[1−α(1−x)]n where n is the number of NADH-binding sites per protein molecule. 3. The co-operative binding of GTP to bovine glutamate dehydrogenase in the presence of NADH gives a linear relationship between F and α. 4. The prediction from the equation F=[1−α(1−x)]n that initial tangents to non-linear protein-fluorescence-quenching curves will intercept the fluorescence when α=1 at a value of total ligand concentration less than the sum of the concentration of binding sites in the solution plus the dissociation constant of ligand is quantitatively fulfilled. 5. Non-linear protein-fluorescence titrations may be used to obtain information about the distribution of ligand among the protein molecules in solution.
