Descending thoracic aortic aneurysm rupture during postpartum period

Aortic aneurysm refers to the pathological dilatation of the normal aortic lumen involving one or several segments. Thoracic aortic aneurysms are much less common than aneurysms of the abdominal aorta. Descending thoracic aortic aneurysm leading to dissection and spontaneous rupture is a potentially catastrophic illness. Although rare, dissection and rupture of a preexisting aortic aneurysm have been reported during pregnancy and early puerperium. To the best of our knowledge, such cases among young pregnant women are rarely reported in literature. Herein, an autopsy case of spontaneous rupture of a clinically undiagnosed descending thoracic aortic aneurysm during early puerperium in a young woman is presented along with the review of relevant literature. The victim was found dead on her hospital bed on the seventh day of puerperium. Autopsy with ancillary investigations revealed that the young woman died because of hemothorax from a ruptured dissecting descending thoracic aortic aneurysm secondary to chronic aortitis.     

Biased Sanctions? Methodological Change in Economic Sanctions Reconsidered and Its Implications

We investigate the influence of case selection and (re)coding for two vintages of a key resource for research on economic sanctions: the Peterson Institute database reported in Hufbauer et al. (second edition in 1990 and third edition in 2007, often identified by their abbreviations HSE and HSEO). The Peterson Institute has not transparently reported about these changes. These changes make it more likely to find sanction success. A multivariate probit analysis establishes upward bias related to modest policy change, duration, and cost to target and downward bias for regime change, military impairment, companion policies, and cost to the sender.     

Understanding the academic learning of university students using smartphone: Evidence from Pakistan

As the number of smartphone users have increased worldwide, research on the usage of the smartphone has received scholarly attention. However, different results were found in previous studies in different contexts. The main research question is whether adopting smartphones by students improve learning or generates interference. The purpose of this study is to examine the usage of smartphone among university students in Pakistan. Using a survey approach, data were collected from different universities/colleges of Karachi, Sindh, Pakistan. total, 585 entries was analyzed using SPSS 21.0 and AMOS 21.0 software. Results of analysis, validated most of the hypothesis showing the intention of Pakistani students towards smartphone usage for academic purpose. In addition, findings confirm that students' self‐efficacy related to a smartphone works as a moderating role of intention to use a smartphone for learning and actual usage of the smartphone. The current study has several implications in terms of smartphone usage and student academic performance. Limitations and implications of the study are also discussed in the last section.     

Dark side of social media and academic performance of public sector schools students: Role of parental school support

Students are regularly engaged in several things at the same time during class and school time. They are using smartphones, tablets, laptops, and using social media on these devices while learning and attending class. However, there are some situations likely influenced by this, current study tests the influence of technostress, cyberbullying, and media multitasking in the context of students in technology‐saturated classrooms and how this is affecting their academic performance. This study further explored the buffering effects of parental school support on the relationship between technostress, cyberbullying, and student's performance. By using the person‐environment fit model, this study surveyed 248 public sector school students in two waves and examined the impact of these variables on student's academic performance. Results show that technostress, cyberbullying, and media multitasking have a negative impact on student performance, and school parental support moderates the negative relationship between technostress and student performance. Implications and contributions have also been discussed.
