亲爱的父亲们,节日快乐!

Hi Brad, The Father's Day is coming.I am always too shy to express my feeling to my father as he,in my eyes,is so serious.Maybe his action has said all for him,and there's so little left to the words.Brad,do you also prefer to have actions instead of words to say everything for you? Please tell me more about your story of being a father.     

你好,夏威夷!

半年不见的Brad又回来了!喜欢旅行和爱好广泛的他,似乎永远都会为我们带来不同的精彩故事和见闻。那让我们依旧跟随他的文字和图片,穿越空间上的距离,一同享受那游走在世界的美丽心情!

Exercise cardiac power and the risk of heart failure in men: A population-based follow-up study

Background:Little is known about exercise cardiac power(ECP),defined as the ratio of directly measured maximal oxygen uptake with peak systolic blood pressure during exercise,on heart failure(HF)risk.We examined the association of ECP and the risk of HF.Methods:This was a population-based cohort study of 2351 men from eastern Finland.The average time to follow-up was 25 years.Participants participated at baseline in an exercise stress test.A total of 313 cases of HF occurred.Results:Men with low ECP(<9.84 mL/mmHg,the lowest quartile)had a 2.37-fold(95%confidence interval(95%CI):1.68-3.35,p<0.0001)hazards ratio of HF as compared with men with high ECP(>13.92 mL/mmHg,the highest quartile),after adjusting for age.Low ECP was associated with a 1.96-fold risk(95%CI:1.38-2.78,p<0.001)of HF after additional adjustment for conventional risk factors.After further adjustment for left ventricular hypertrophy,the results hardly changed(hazards ratio=1.87,95%CI:1.31-2.66,p<0.001).One SD increase in ECP(3.16 mL/mmHg)was associated with a decreased risk of HF by 28%(95%CI:17%-37%).Conclusion:ECP provides a noninvasive and easily available measure from cardiopulmonary exercise tests in predicting HF.However,ECP did not provide additional value over maximal oxygen uptake.     

Paying back student loans: Demographic,human capital and other correlates of default and repayment difficulty

Government‐sponsored student loans have emerged over the decades as a primary method of financing post‐secondary education across most North American jurisdictions. Despite this, the empirical literature examining the correlates of repayment difficulty and default in Canada has remained stagnant in recent years. This study taps into an underutilised data source—the 2013 National Graduates Survey—to examine the relationship between demographics, human capital, borrowing behaviour and other known predictors and repayment difficulty. Our logistic regression models demonstrate that disability status, geographic region and borrowing behaviour are correlated with loan default and repayment difficulty, while failing to verify the existence of other demographic effects routinely found in the existing literature. We discuss the implications of these findings, along with multiple avenues for further empirical work on this topic within Canada.     

Ebooks in Academic Libraries

Abstract

The number of ebooks continues to grow in academic libraries. Ebooks have many advantages that make them attractive as a library resource. However, ebooks also have restrictions. These include use and sharing restrictions, license restrictions, and technological barriers. Some students also prefer print books for specific tasks. The following articles examine many aspects of ebooks in academic libraries, including student preference, overall ebook use, and the advantages and disadvantages of various ebook acquisition models.
