This study empirically investigates the antecedent, mediating, and outcome variables of budgetary participation in Turkey. Turkey is an interesting setting to investigate the impact of budgetary participation on job satisfaction and performance because of its unique cultural and institutional factors. We propose that the information asymmetry between superiors and subordinates creates the need for budgetary participation, and the outcomes of budgetary participation (i.e., job satisfaction and performance) will be mediated by goal commitment and role ambiguity. Based on a questionnaire survey of 194 mid-level managers in Turkey, we find that role ambiguity mediates the budgetary participation–job satisfaction and budgetary participation-performance relationships. The results are consistent with the view that the primary benefit of budgetary participation is to decrease role ambiguity, leading to more job satisfaction and better performance. Furthermore, we find that goal commitment mediates the budgetary participation-performance relationship. This result suggests that participation in the budgeting process increases goal commitment, which in turn leads to better performance. This study will be beneficial for companies in general and for organizations in developing countries in particular to realize that budgetary participation alone does not improve job satisfaction and performance. Rather, it is the increased commitment and decreased role ambiguity that results from managers' participation in the budgetary process that improves job satisfaction and performance.

Background The number of pediatric patients who survive open-heart surgery has increased in recent years and the complications seen in this patient group continue to decrease with each technological advance, including new surgical and neuroprotective techniques and the improvement in surgeons’ experience with this patient population. However, neurological complications, which are the most feared and difficult to manage, require long-term follow-up, and increase hospital costs remain a leading cause of mortality and morbidity in this cohort. Results We evaluated the neurological physical examination, cranial computed tomography (CT), and magnetic resonance (MRI) records of 162 pediatric patients with neurological symptoms lasting more than 24 h after undergoing heart surgery in our clinic between June 2012 and May 2020. The patients’ ages ranged from 0 to 205 months, with a mean of 60.59 ± 46.44 months. Of the 3849 pediatric cardiac surgery patients we screened, 162 had neurological complications in the early period (the first 10 days after surgery). The incidence was calculated as 4.2%; 69 patients (42.6%) experienced seizures, 17 (10.5%) experienced confusion, 39 (24.1%) had stupor, and 37 (22.8%) had hemiparesis. Of the patients who developed neurological complications, 54 (33.3%) died. Patients with neurological complications were divided into 3 groups: strokes (n = 90), intracranial bleeding (n = 37), and no radiological results (n = 35). Thirty-four patients (37.8%) in the stroke group died, as did 15 (40%) in the bleeding group, and 5 (14.3%) in the no radiological results group. Conclusions Studies on neurological complications after pediatric heart surgery in the literature are currently insufficient. We think that this study will contribute to a more detailed discussion of the issue. Responses to neurological events and treatment in the pediatric group may differ compared to the adult age group. Primary prevention methods should be the main approach in combating neurological complications; their formation mechanisms should be carefully monitored and preventive treatment strategies should be developed.

Background: It is difficult to predict the complications and prognosis of ECMO, which is gaining widespread use in patients with pediatric surgery. Platelet-to-lymphocyte ratio (PLR) and neutrophil-to-lymphocyte ratio (NLR) are emerging inflammatory markers that can be calculated from complete blood count, which is a cheap and easily accessible laboratory analysis. The ratios between cellular elements in peripheral blood have been demonstrated to provide information on inflammation, infection, and immune response. Methods: Sixty-seven patients who needed ECMO application after undergoing pediatric cardiovascular surgery in our clinic, between May 2005 and April 2020, were included in this study. The age of patients varied between 4 days and 17 years with a mean of 30.59 ± 147.26 months. Results: The relationships between PLR or NLR values and various blood parameters and blood gas results were found to be statistically nonsignificant in our group of pediatric ECMO recipients. Even if the effect of PLR and NLR values on mortality and prognosis is statistically nonsignificant in patients who need ECMO after congenital heart surgery, PLR and NLR are typically elevated in the postoperative period. An increase in these values above a certain threshold may be a statistically significant indicator for the prediction of mortality. Conclusions: There are few studies in the literature concerning PLR and NLR values in patients with pediatric heart surgery. We consider this study will make way for new studies in the future.

Prior research on the relationship between volatility and growth has produced mixed results. However, the times series research has only been done for a few countries, namely the United States, United Kingdom and Japan. We extend the prior research by performing a systematic search over several GARCH in mean model specifications, including nonGaussian and asymmetric GARCH models, for 20 OECD countries. The results indicate very little evidence of any connection between volatility and growth.

We investigated the influence of exchange rate volatility on foreign trade for an emerging economy, namely Turkey, by using monthly data spanning from 1990 to 2015. We employed the Johansen cointegration test, the vector error correction model, or VECM, and the VAR Granger causality test within the framework of the Toda-Yamamoto procedure in order to capture both the long-term and short-term effects of exchange rate volatility. We report that there is a long-term relationship between exchange rate volatility and Turkish exports. In addition, while exchange rate volatility has a positive effect on Turkish exports in the long-term, this relationship disappears in the short-term.

Introduction In this trial, we initially aimed to investigate the major predictive factors for prolonged mechanical ventilation (PMV) following cardiac surgery with cardiopulmonary bypass (CPB) in our center and, secondarily, we tried to find out the effects of the independent factors on mortality. Methods Between July 2017 and August 2018, 207 patients who underwent cardiac surgery with CPB were retrospectively investigated. The patients were randomly divided into two subgroups according to the duration of ventilator dependence (group 1 <24 hours, n=164, 79%; group 2 >24 hours, n=43, 21%). Results 207 patients (mean age 59.47±10.56) who underwent cardiac surgery with CPB were enrolled in this study (n=145, 70% of male patients; n=62, 30% of female patients). Amid these patients, 43 (n=43, 20.77%) had prolonged intubation time. After multivariate logistic regression analysis among preoperative factors, female gender (OR=2.321, P =0.028), leukocytosis (OR=1.233, P =0.006), perioperative lactate level (OR=1.224, P =0.027), CPB time (OR=1.012, P =0.012) and postoperative revision for bleeding (OR=23.125, P =0.040) were significantly detected. The effect of predictive factors on mortality after cardiac surgery was determined and found that PMV did not affect hospital mortality (OR=1.979, P =0.420). Conclusion In our report, we revealed, differently from previous studies, that intraoperative lactate levels which manifest organ perfusion and oxygenation were included and were significantly different in the early extubation group compared to the PMV group. Female gender, preoperative leukocytosis, intraoperative CPB time, lactate levels and postoperative revision for bleeding were the independent predictive factors for PMV. Moreover, PMV did not affect the early-term mortality during hospital stay.
