Purpose: The aim of the present study was to investigate a potential difference on the arterial stiffness among aneurysm patients and non-aneurysm controls, as well as to explore potential changes between patients treated either with endovascular or open repair. Materials and Methods: A 110 patients with an infrarenal AAA were prospectively enrolled in this study. Fifty-six patients received an EVAR, whereas 54 patients received an open surgical repair. Moreover, 103 gender and age-matched subjects without AAA served as controls. The cardio-ankle vascular index (CAVI) was applied for measurement of the arterial stiffness. Results: CAVI values were statistically higher in the AAA patients when compared with control subjects. Although at 48 hours postoperatively the CAVI values were increased in both groups when compared to baseline values, the difference in CAVI had a tendency to be higher in the open group compared to the endovascular group. At 6 months of follow up the CAVI values returned to the baseline for the patients of the open repair group. However, in the endovascular group CAVI values remained higher when compared with the baseline values. Conclusion: Patients with AAAs demonstrated a higher value of CAVI compared to healthy controls. A significant increase of arterial stiffness in both groups during the immediate postoperative period was documented. The increase in arterial stiffness remained significant at 6 months in EVAR patients. Further studies are needed to elucidate the impact of a decreased aortic compliance after stentgraft implantation on the cardiac function of patients with AAA.

The urban fabric of the desert cities is based on the principle of reducing the impact of urban canyons on direct solar radiation. Here comes this research, which is based on a comparative study of the periods of direct solarisation and values of the solar energy of urban canyons via two urban fabrics that have different building densities, where the ratio between L/W is different. In order to obtain the real values of the solar energy (thermal, lighting), the test field was examined every two hours, each three consecutive days. The measurement stations are positioned by the three types of the relationship between L/W, (L≥2w, L=w, L≤0.5w). According to the results, we noticed and recorded the difference in the periods of direct solarization between the types of urban engineering canyons, reaching 6 hours a day, the difference in thermal values of air, reaching 4 °C, and the difference in periods of direct natural lighting, reaching 6 hours. It should be noted that the role of the relationship between L/W is to protect the urban canyons by reducing the impact of direct solar radiation on urban canyons, providing longer hours of shading, and reducing solar energy levels (thermal, lighting) at the urban canyons. This research is classified under the research axis (the studies of external spaces in the urban environment according to the bioclimatic approach and geographic approach). But this research aims to focus on the tracking and studying the distribution of the solar radiation - thermal radiation and lighting radiation - in different types of street canyons by comparing the study of the direct solarization periods of each type and the quantity of solar energy collected during the solarization periods.

It was recently demonstrated that performing median splits on both of two predictor variables could sometimes result in spurious statistical significance instead of lower power. Not only is the conventional wisdom that dichotomization always lowers power incorrect, but the current article further demonstrates that inflation of apparent effects can also occur in certain cases where only one of two predictor variables is dichotomized. In addition, we show that previously published formulas claiming that correlations are necessarily reduced by bivariate dichotomization are incorrect. While the magnitude of the difference between the correct and incorrect formulas is not great for small or moderate correlations, it is important to correct the misunderstanding of partial correlations that led to the error in the previous derivations. This is done by considering the relationship between partial correlation and conditional independence in the context of dichotomized predictor variables.

SUMMAYWe studied the relationship between IgA anti–campylobacter flagellin antibodies in breast milk samples and protection of breastfed infants living in a rural Mexican village from campylobacter infection. There were fewer episodes of campylobacter infection (symptomatic and asymptomatic combined) in infants breastfed with milk containing specific anti-flagellin antibodies (1.2/child/year, 95% CI 0.6–1.8) versus non–breastfed children (3.3/child/year, 95% CI 1.8–4.8; P < 0.01). Infants breastfed with milk that was antiflagellin antibody negative by ELISA also had fewer episodes of infection compared with non-breastfed children, but the difference did not reach statistical significance (1.8/child/year, 95% CI 0.7–3.0 versus 3.3/child/year, 95% CI 1.8–4.8, P > 0.05). Breastfeeding has a protective effect against campylobacter infection and is associated with the presence of specific antibodies directed against campylobacter flagellin.

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] This study is an examination of the relationship between political connections and the undertaking of major firm events. In our first essay, presented in Chapter 3, we examine the impact politically connected appointments have on firm acquisition behavior. Using proxy statements, we create a unique database of politically connected bidders and merger targets. We find that bidders who hire connected individuals to the board or management team are more likely to avoid merger litigation. Connected bidders make more bids after the appointment. These firms also bid on larger targets. We determine there is a positive relation between the control premium and the relative of the target's connections. Connected acquirers have superior post-merger accounting performance, particularly when they acquire a connected target firm. In the second essay, presented in Chapter 4, we examine the relationship between political connections of private firms and the initial public offering process. Using registration statement information, we create a unique database of politically connected IPO firms. We find that political connections are substitutes to high-quality underwriters and big four auditors. Politically connected firms manage earnings more highly upward than non-connected firms prior to the public offering. Politically connected firms also exhibit less underpricing than non-connected firms. Politically connected IPO firms also have superior post-IPO returns relative to non-connected IPO firms.

Background. Patients (pts) diagnosed with congestive heart failure (HF) have been reported to have more frequent depression and worsened health related quality of life (HRQOL). Although depression is more common in women than men in this condition, the impact of HF on depression and HRQOL in men versus women is unclear. We sought to examine the relationship between pt sex, HF diagnosis, and pt-perceived depression and HRQOL. Methods. Depression (PHQ-9) and HRQOL (EQ5D) data were collected using tablet computers from pts presenting for routine outpatient cardiovascular assessment at our institution between November, 2010 and December, 2011. Demographic, clinical, and historical data was collected as per routine. We examined the association of pt sex and clinical diagnosis of HF with instrument results after adjusting for potential confounding information using mutliple linear regression. Results. Of 3046 pts (age 61±15), 39% were female and 8.7% were diagnosed with HF. Overall, PHQ-9 was greater, and minor or major depression (PHQ-9≥10) was more frequent, in women than men (4.6±4.6 vs. 3.3±4.4; 14.0% vs. 8.9%, both p<0.05) and in HF pts than pts without HF (5.9±5.6 vs. 3.6±4.3, 22.0% versus 9.6%; both p<0.05). Similarly, HRQOL was worse in women than men (EQ-5D 0.80±0.18 vs. 0.87±0.16; p<0.01) and in HF pts than no HF (EQ-5D 0.76±0.18 vs. 0.85±0.17; p<0.01). However, the difference in PHQ-9 between pts with versus without HF was greater in men (6.23±6.06 vs. 3.02±4.06, p<0.01) than women (5.43±4.85 vs. 4.55±4.58, p=0.09). After adjusting for cardiovascular diagnoses, comorbidities, clinical and demographic data, multivariable modeling of PHQ-9 revealed a significant interaction between pt sex and HF diagnosis (p=0.001; see Figure) such that women had greater PHQ-9 scores compared to men without HF, but in the setting of HF, mens' PHQ-9 scores were greater. Modeling of EQ-5D also revealed that after risk-adjustment an interaction between HF diagnosis and sex was present with a similar pattern of findings. Conclusion. Although depression is more frequent and severe in women compared to men, and in pts with versus without HF, HF appears to impact depression severity more in men compared to women.

This study examines the impact of Autocratic leadership on Disruptive Political Behavior with the moderating effect of Abusive Supervisory Behavior and the mediating effect of Employee Perception of Job Insecurity. It examines the employee perception of job insecurity while working in an autocratic culture and the political strategies which an employee chooses to cope up with such insecurities. The data was collected through a structured questionnaire from a sample of 248 employees which include middle-level managers, front-line managers, and their employees. Pearson correlation test was used to establish the relationship between variables. Findings reveal the existence of a significant positive relationship between the variables. Result also prove that there is a significant positive moderation of abusive supervisory behavior between the relationship of autocratic leadership and employee perception of job insecurity, and shows partial significance with mediating effect of employee perception of job insecurity with the relation of autocratic leadership and disruptive political behavior. The study concludes with a discussion and future directions.

Purpose This study aims to investigate the impact of three determinants of organizational identification (OID) on employee performance (EP) in the context of private business institutions. Design/methodology/approach A sample of 175 permanent faculty members from four top universities in Karachi, Pakistan, was interviewed using a five-point Likert scale questionnaire. The data were inserted in SPSS 22 and SmartPLS v 3.2 for performing the analysis. Findings Results of the study showed a significant effect in perceived supervisor support on OID; OID; job satisfaction and EP; and mediating relationship. Conversely, an insignificant effect was observed in workplace incivility. Research limitations/implications It is highly recommended that organizations work on the areas that lead to enhancing their employees’ performance. Also, human resource should create a healthy culture that promotes initiatives, open-door policies and discourages power distance. Lastly, one of the key responsibilities of management is to strengthen their OID because employees are more likely to identify with their supervisors if they invest in the organizations they work for. Practical implications This study will help strengthen the relationship between supervisors and university employees. It will guide the supervisors to acknowledge and appreciate the efforts of their subordinates and develop recreational policies and employee engagement activities. In addition, it will help develop a conducive environment and enhance the quality of education in the university and the society. Originality/value Understanding the determinants of OID on EP in the educational context is very important as it enhances the quality of EP and the overall quality of education of the institution.

Social and emotional difficulties are common during the kindergarten stage, the changes between family and school environment leave the child at risk of a range of emotional and social problems at that point. This pressure confronts the child's weak ability at that age, linguistically, to express his feelings and thoughts in a clear and understandable manner, as well as the beginning of his ability to control and organize his feelings and behaviors. All this constitutes factors that make the child's adaptation process on the emotional, social and cognitive level difficult during the kindergarten stage. While many studies confirm that the child is an emotional and social being par excellence, and while educational programs emphasize in most of their content on cognitive learning, the child's needs, personality and sentiments are ignored, hence the question raised about the role of emotional competencies in establishing other competencies? Since the kindergarten stage by its nature requires that the child learn to adapt to the environment and establish healthy relationships, our paper aims to study the relationship between emotional competencies (Self-awareness and Self-regulation*) and their indicators and social competencies (Social awareness and Relationships skills*) and their indicators and determine the mutual impact between them. As a tool for this study we used SEAM scale to measure emotional and social competencies to measure the relationship between emotional variables as an independent variable to see its effect on the dependent variable, which is in our study social competencies. Using the inferential statistics (Pearson correlation coefficient and simple linear regression coefficient) to measure the relationship between two variables, results demonstrated that there is a positive semantic relationship confirms that emotional competencies and their determinants are highly influential competencies that establish social competencies and their determinants at preschool age. Participant were 191 children, aged 4 to 6 years old at the time initial assessment, in kindergarten, within the group of schools relied to the Moroccan Foundation for promoting preschool education.
