The relationship between talent management practices and retention of generation ‘Y’ employees: mediating role of competency development

In a competitive marketplace, retention of talented and younger employees is a challenge for organizations. Thus, it becomes important for organizations to execute employees’ development strategies to retain Generation Y employees. The goal of this research is to analyze the effect of talent management (TM) practices i.e. mentoring, strategic leadership, social media, and knowledge sharing on the intention to stay of generation Y employees and strengthening this relationship by investigating the mediating role of competency development. A total of 372 employees of generation Y participated in the study. The data were analyzed through the PLS-SEM model using smartPLS-3 software. Findings reveal that TM practices: mentoring, strategic leadership, social media positively affect the intention to stay of generation Y employees, while knowledge sharing has no significant effect on the intention to stay. Competency Development mediates the relationship between strategic leadership, social media, knowledge sharing and intention to stay. However, competency development does not significantly mediate the relationship between mentoring and intention to stay

The role of instrumental guanxi in the relation between entrepreneurs’ social competence and firms’ financial performance: A comparative study

Even though many studies have examined the role of instrumental guanxi in the formation and development of entrepreneurship, how instrumental guanxi and social competence support entrepreneurs in enhancing firm financial performance (FFP) has not been investigated. Thus, this study investigates the relationship between entrepreneurs’ social competence and FFP in the textile industry of China and Pakistan to examine how instrumental guanxi mediates the said relationship. In Studies 1 and 2, 251 Chinese and 270 Pakistani entrepreneurs, respectively, were randomly selected. The partial least square structural equation modelling approach was employed to evaluate the data. In Study 1, social perception, impression management, and expressiveness have a positive and significant impact on FFP. Moreover, instrumental guanxi partially mediates the impact of all dimensions of social competence except social perception. In Study 2, impression management, persuasiveness, and expressiveness have a positive and significant impact on FFP, and instrumental guanxi partially mediates the impact of social adaptability on FFP. Given the competitive advantage theory, both groups of entrepreneurs can mutually support and enhance their social competence as well as FFP

Ruptured mycotic aneurysms: Report and outcomes of two surgically managed patients

Background: Mycotic aneurysm is a rare potentially life-threatening complication of infective endocarditis (IE). Little data is available on the management and outcomes of ruptured mycotic aneurysms with large intracerebral hematoma. Few cases have been described on the management of mycotic aneurysm in the presence of life-threatening hematoma and mass effect.Case description: We are presenting two cases of ruptured mycotic aneurysm with intracerebral hematoma and impending brain herniation. Both patients had signs of high intracranial pressure and required urgent surgical evacuation of clot. One patient survived while the other patient expired soon after surgery.Conclusion: Mycotic aneurysm of middle cerebral artery (MCA) in IE with intracranial hemorrhage is rare and urgent surgical decompression, and aneurysmal clipping can be lifesaving

Carotid Intima Media Thickness Percentiles for Pakistani Population

Carotid artery intima media thickness estimation is a well-established way of cardio vascular disease evaluation. The purpose of this cross-sectional study was to develop normal carotid intima media thickness percentile values for a Pakistani cohort. Data was collected at the Departments of Radiology and Family Medicine, The Aga Khan University Hospital, Karachi, from April 2014 to August 2015. High frequency ultrasound of carotid was done in 257 patients [97 male (38%), 160 female (62%)] without any known carotid artery disease. Reference ranges (90% range between 5th and 95th centiles) were constructed for each common carotid and internal carotid artery measurement and displayed in graph form. The mean difference was found in left common carotid artery (0.55 ±0.13) and left internal carotid artery thickness (0.50 ±0.10) significant at p=0.031 and p=0.014, respectively. The IMTpercentile graphs developed in this study for internal and common carotid arteries are exclusive for this population and can be used to assess vascular health from ultrasound measurements

Evaluation of erectile dysfunction with color Doppler sonography

Objective: To assess the role of Color Doppler Sonography in the evaluation of erectile dysfunction.Methods: A cross-sectional study was conducted at the Radiology Department, Aga Khan University Hospital Karachi from 5-6-2002 to 2-9-2003. All consecutive patients presenting with erectile dysfunction and undergoing penile color Doppler evaluation with injection PGE1 20 mcg were included in this study.Results: A total of 70 patients with an age range of 24-70 years (mean 41 +/- 12.25 years) were included in the study. A normal response was noted in 45 (psychogenic) cases. Vasculogenic causes were observed in 23 patients, 12 with arterial insufficiency and 11 with venous leak. Peyronie\u27s disease was diagnosed in 2 patients.CONCLUSION: Color Doppler evaluation of erectile dysfunction is an effective method for differentiating psychogenic and vasculogenic causes of erectile dysfunction

Carotid intima media thickness evaluation by ultrasound comparison amongst healthy, diabetic and hypertensive Pakistani patients

Objective: To compare carotid Intima media thickness and atherosclerosis burden amongst healthy, diabetic and hypertensive Pakistani patients.Methods: A cross-sectional study was carried out at the Department of radiology and family medicine, Aga Khan University Hospital Karachi from April 2014 to July 2015. Bilateral carotid ultrasound was done in 133 healthy adults, 65 hypertensive, 31 type-2 diabetic and 37 hypertensive with type-2 diabetes patients. Normal adults were matched for age and gender. Mean intimal media thickness was measured for common and internal carotid arteries. Presence or absence of atherosclerotic plaque was also identified. Height, weight, ethnicity, socioeconomic status and other risk factors were also assessed. Ultrasound findings were compared between healthy and diseased patients through statistical tests.Results: A total of 266 patients participated (Controls=133, Hypertensive=65, Diabetic=31, and Diabetes with Hypertension=37). There was no significant difference in the baseline characteristics between the four patients\u27 groups for age (p\u3e0.05) and gender (p\u3e0.05). The mean carotid intima media thickenss of right common carotid artery was significantly higher in patients with diabetes along with hypertension as compared to the control group (p=0.03). For (RICA) Right Internal Carotid Artery, (LCCA) Left Common Carotid Artery and (LICA) Left Internal Carotid Artery, there was a significantly higher thickness among patients with hypertension as compared to the control group with p=0.011, p=0.002, and p=0.039 respectively.Conclusion: Increased CIMT is most likely associated with underlying chronic diseases. Ultrasound is a non-invasive, easily available and useful modality for early detection and prevention of vascular atherosclerosis

Physics Potential of the ICAL detector at the India-based Neutrino Observatory (INO)

The upcoming 50 kt magnetized iron calorimeter (ICAL) detector at the India-based Neutrino Observatory (INO) is designed to study the atmospheric neutrinos and antineutrinos separately over a wide range of energies and path lengths. The primary focus of this experiment is to explore the Earth matter effects by observing the energy and zenith angle dependence of the atmospheric neutrinos in the multi-GeV range. This study will be crucial to address some of the outstanding issues in neutrino oscillation physics, including the fundamental issue of neutrino mass hierarchy. In this document, we present the physics potential of the detector as obtained from realistic detector simulations. We describe the simulation framework, the neutrino interactions in the detector, and the expected response of the detector to particles traversing it. The ICAL detector can determine the energy and direction of the muons to a high precision, and in addition, its sensitivity to multi-GeV hadrons increases its physics reach substantially. Its charge identification capability, and hence its ability to distinguish neutrinos from antineutrinos, makes it an efficient detector for determining the neutrino mass hierarchy. In this report, we outline the analyses carried out for the determination of neutrino mass hierarchy and precision measurements of atmospheric neutrino mixing parameters at ICAL, and give the expected physics reach of the detector with 10 years of runtime. We also explore the potential of ICAL for probing new physics scenarios like CPT violation and the presence of magnetic monopoles.Comment: 139 pages, Physics White Paper of the ICAL (INO) Collaboration, Contents identical with the version published in Pramana - J.
