FDI And Economic Growth. Evidence From Simultaneous Equation Models

This paper analyses whether foreign direct investments have an impact on the Romanian economic growth. By means of simultaneous equation methods we obtained evidence of the bi-directional connection between the two, meaning that incoming FDI stimulates economic growth and, in its turn, a higher GDP attracts FDI. Two methods were used in performing the analysis, one considering the relation between the share of FDI in GDP and economic growth in a five-equation system and the second considering the levels of FDI and GDP, respectively, in a two-equation system.foreign direct investment, economic growth, simultaneous equation models

Predicting financial distress for Romanian companies

Using a moderately large number of financial ratios, we tried to build models for classifying the companies listed on the Bucharest Stock Exchange into low and high risk classes of financial distress. We considered four classification techniques: Support Vector Machines, Decision Trees, Bayesian logistic regression and Fisher linear classifier, out of which the first two proved to have the highest prediction accuracy. Classifiers were trained and tested on randomly drown samples and on four different databases built starting from the initial financial indicators. As the literature related to the topic on Romanian data is very scarce, our study, by using a variety of methods and combining feature selection and principal components analysis, brings a new approach to predicting financial distress for Romanian companies.

3-D Echocardiography Is Feasible and More Reproducible than 2-D Echocardiography for In-Training Echocardiographers in Follow-up of Patients with Heart Failure with Reduced Ejection Fraction

Left ventricular volumes (LVVs) and ejection fraction (LVEF) are key elements in the evaluation and follow-up of patients with heart failure with reduced ejection fraction (HFrEF). Therefore, a feasible and reproducible imaging method to be used by both experienced and in-training echocardiographers is mandatory. Our aim was to establish if, in a large echo lab, echocardiographers in-training provide feasible and more reproducible results for the evaluation of patients with HFrEF when using 3-dimensional echocardiography (3-DE) versus 2-dimensional echocardiography (2-DE). Sixty patients with HFrEF (46 males, age: 58 ± 17 y) underwent standard transthoracic 2-D acquisitions and 3-D multibeat full volumes of the left ventricle. One expert user in echocardiography (expert) and three echocardiographers with different levels of training in 2-DE (beginner, medium and advanced) measured the 2-D LVVs and LVEFs on the same consecutive images of patients with HFrEF. Afterward, the expert performed a 1-mo training in 3-DE analysis of the users, and both the expert and trainees measured the 3-D LVVs and LVEF of the same patients. Measurements provided by the expert and all trainees in echo were compared. Six patients were excluded from the study because of poor image quality. The mean end-diastolic LVV of the remaining 54 patients was 214 ± 75 mL with 2-DE and 233 ± 77 mL with 3-DE. Mean LVEF was 35 ± 10% with 2-DE and 33 ± 10% with 3-DE. Our analysis revealed that, compared with the expert user, the trainees had acceptable reproducibility for the 2-DE measurements, according to their level of expertise in 2-DE (intra-class coefficients [ICCs] ranging from 0.75 to 0.94). However, after the short training in 3-DE, they provided feasible and more reproducible measurements of the 3-D LVVs and LVEF (ICCs ranging from 0.89-0.97) than they had with 2-DE. 3-DE is a feasible, rapidly learned and more reproducible method for the assessment of LVVs and LVEF than 2-DE, regardless of the basic level of expertise in 2-DE of the trainees in echocardiography. In echo labs with a wide range of staff experience, 3-DE might be a more accurate method for the follow-up of patients with HFrEF

Multicentric Atrial Strain COmparison between Two Different Modalities: MASCOT HIT Study

Two methods are currently available for left atrial (LA) strain measurement by speckle tracking echocardiography, with two different reference timings for starting the analysis: QRS (QRS-LASr) and P wave (P-LASr). The aim of MASCOT HIT study was to define which of the two was more reproducible, more feasible, and less time consuming. In 26 expert centers, LA strain was analyzed by two different echocardiographers (young vs senior) in a blinded fashion. The study population included: healthy subjects, patients with arterial hypertension or aortic stenosis (LA pressure overload, group 2) and patients with mitral regurgitation or heart failure (LA volume–pressure overload, group 3). Difference between the inter-correlation coefficient (ICC) by the two echocardiographers using the two techniques, feasibility and analysis time of both methods were analyzed. A total of 938 subjects were included: 309 controls, 333 patients in group 2, and 296 patients in group 3. The ICC was comparable between QRS-LASr (0.93) and P-LASr (0.90). The young echocardiographers calculated QRS-LASr in 90% of cases, the expert ones in 95%. The feasibility of P-LASr was 85% by young echocardiographers and 88% by senior ones. QRS-LASr young median time was 110 s (interquartile range, IR, 78-149) vs senior 110 s (IR 78-155); for P-LASr, 120 s (IR 80-165) and 120 s (IR 90-161), respectively. LA strain was feasible in the majority of patients with similar reproducibility for both methods. QRS complex guaranteed a slightly higher feasibility and a lower time wasting compared to the use of P wave as the reference

Predictors of Marital Adjustment: Are There Any Differences Between Women and Men?

The purpose of this study was to explore if there are differences between women and men in relationships among family-of-origin, romantic attachment, and marital adjustment. Two hundred and forty-nine participants filled out four self-reported measures: The Differentiation in the Family System Scale, Family Adaptability and Cohesion Evaluation Scale, Experiences in Close Relationship Scale, and Revised Dyadic Adjustment Scale. In order to analyze the data, multiple-group analysis with AMOS 16.0 was used. There was no difference between women and men in all observed variables. Regardless of gender, only the romantic attachment was a significant predictor of marital adjustment. Only in women, family-of-origin significantly predicted their romantic attachment. Across gender groups, the configural model fitted satisfactorily the observed data. When measurement and structural weights, as well as residuals were constrained to be equal across gender groups, the invariance of the model was also supported. The results suggest women and men could be similar when it comes to the relationships among constructions they both have regarding family-of-origin experiences, romantic attachment patterns, and marital adjustment. Some implications for research and clinical practice with marital couples are briefly discussed

Left atrial dysfunction as a correlate of heart failure symptoms in hypertrophic cardiomyopathy.

BACKGROUND: Hypertrophic cardiomyopathy (HCM) represents a generalized myopathic process affecting both ventricular and atrial myocardium. We aimed to assess left atrial (LA) function by two-dimensional speckle tracking echocardiography and its relation with left ventricular (LV) function and clinical status in patients with HCM. METHODS: We prospectively enrolled 37 consecutive patients with HCM and 37 normal subjects with similar age and gender distribution. Longitudinal LV strain (epsilon) and LA epsilon and strain rate (Sr) parameters (systolic, early diastolic, and late diastolic during atrial contraction) were assessed. RESULTS: Peak LAepsilon and LA Sr parameters were significantly lower in patients compared with controls (P </= .001 for all). In patients, all LA function parameters correlated with LVepsilon (P < .003 for all). Indexed LA volume, LA function parameters, and mitral regurgitation degree were the main correlates of New York Heart Association class; late diastolic strain rate during atrial contraction was the only independent predictor of symptomatic status. CONCLUSION: In patients with HCM, LA function is significantly reduced and related to LV dysfunction. Moreover, LA booster pump function emerged as an independent correlate of heart failure symptoms in this setting
