Abstract There continues to be controversy on the long‐term effects of a patent ductus arte‐ riosus (PDA) and its management. However, the hemodynamic effects of a large PDA in a preterm infant are well known. This article aims to provide insight into the adap‐ tive changes and remodeling effects of a PDA on the myocardium in preterm infants. More >

Abstract Surgical ligation of patent ductus arteriosus can be performed safely by following standard steps of operation. Familiarity of the anatomical landmarks and simple pre‐ cautions result in high degree of safety. The technique of surgical ligation varies with the age of the patient. Surgical ligation of ductus is associated with well‐recognized complications, although they occur only in a small number of patients. More >

Abstract Patent ductus arteriosus (PDA) is prevalent in premature newborns and has been linked to the development of bronchopulmonary dysplasia (BPD), a serious pulmonary complication of premature birth. Although a causal relationship has not been proven, the link is greatest among infants born at lower gestational age who are treated with mechanical ventilation in the presence of a large ductal shunt. Despite strong association in epidemiological studies, treatment of a patent ductus arteriosus has not been shown to prevent BPD, and some therapies may increase the risk of BPD. We describe preclinical and clinical data demonstrating More >

Abstract In the current digital era, public health campaigns using media has been very successful in giving knowledge and changes the attitudes of people. But till now scarce literature is available related to media campaigns about mental health. In this study Pre-Post Quasi Experimental Design using vignettes as a data collection measure were employed. The participants were categories in to experimental (n = 138) and control (n = 134) groups having 18–55 years of age to evaluate the efficiency of media mediated interventions using social media campaign in increasing Mental Health Literacy (MHL). The results from More >

Abstract Employee well-being has received considerable attention over the past decades. Little has been done to examine the linkage between organizational socialization and work engagement, one of the most important indicators of wellbeing at work. Drawing upon the conservation of resources (COR) theory, we propose and test relationships between organizational socialization, employee psychological capital, work engagement, and leader psychological capital. Using data from 268 newcomers nested within 36 teams, the results show that (1) organizational socialization is positively related to work engagement; (2) employee psychological capital mediates the relationship between organizational socialization and work engagement; (3) More >

Abstract Job insecurity has been recognized for its negative effect on employee performance. Nevertheless, this study argues that, under the threat of job insecurity, employees may also be likely to seek to reduce the threat by proactively crafting their tasks and improving performance. Drawing from the perspective of Vroom’s expectancy theory, it is proposed that, only when job security is at moderate level will employees expect it as possible to make such a change to respond to the situation. Accordingly, a curvilinear mediated model is developed that links job insecurity and task performance indirectly through task… More >

Abstract This paper attempts to unlock how and when leaders’ loneliness influences their voice-taking behavior in the workplace by integrating the regulatory loop model of loneliness and the affect theory of social exchange. Through collecting a daily diary study of 87 paired leader-follower samples from two electronics industry companies based in Guangzhou, China, this study finds that (1) leaders’ loneliness has a significant negative impact on social self-efficacy and voice-taking behavior; (2) leaders’ social self-efficacy mediates the relationship between their loneliness and voice-taking behavior; (3) performance pressure moderates the relationship between leaders’ loneliness and voice-taking behavior; More >

Abstract Based on social cognitive career theory, this research examined a chained mediation model for the relations between proactive personality, career success criteria clarity, career decision-making self-efficacy and affective wellbeing. A two-wave survey study was conducted among Chinese graduating students (N = 235). The results showed that proactive personality (measured at time 1), career success criteria clarity (measured at time 1), and career decisionmaking self-efficacy (measured at time 2) positively related to affective well-being respectively. In addition, the results further revealed that proactive personality was positively related to career success criteria clarity, which further predicted affective well-being More >

Abstract In this paper; the dynamic characteristics of a semi-active magnetorheological fluid (MRF) engine mount are studied. To do so, the performance of the MRF engine mount is experimentally examined in higher frequencies (50~170 Hz) and the various amplitudes (0.01 ~ 0.2 mm). In such an examination, an MRF engine mount along with its magnetically biased is fabricated and successfully measured. In addition, the natural frequencies of the system are obtained by standard hammer modal test. For modelling the behavior of the system, a mass-spring-damper model with tuned PID coefficients based on Pessen integral of absolute More >

Abstract In the current paper, which deals with the noise pollution excited by distribution transformers in the living area, a comprehensive treatment scheme is put forward for the purpose of reducing the sound pressure level emitting into the environment. In accordance with the associated test standard, the sound pressure levels of distribution transformer and surrounding environment are not only tested but analyzed as well. The measurements were carried out with the frequency analysis of the 1/3 octave resolution, with the center frequencies at 125 Hz, 250 Hz, 400 Hz, and 500 Hz. As illustrated, on the… More >
