Reading a paper and Doing Literature Review

Most of the research works are based on papers, both reading papers and writing papers. The efficient way of reading a paper is always personalized by tons of experience. There is one paper about how to read a paper [1], which gives 3 passes for a understanding a paper. As mentioned in [1], the three passes are,
  • The first pass is a quick scan to get a bird's-eye view of the paper. You can also decide whether you need to do any more passes. 
  • In the second pass, read the paper with greater care, but ignore details such as proofs. In the second pass, read the paper with greater care, but ignore details such as proofs. Focus on understanding the figures, make a note of the import references
  • The key to the third pass is to attempt to virtually re-implement the paper: that is, making the same assumptions as the authors, re-create the work. This pass needs great attention to detail.
Doing literature review can be divided into 3 steps as well.
  • First, use an academic search engine and some well-chosen keywords to fi nd three to fi ve recent highly-cited papers in the area. Do one pass to each of the paper to understand the summary of the area. If you can find a good review, done for the first step.
  • Second step, fi nd shared citations and repeated author names in the bibliography. These are the key papers and researchers in that area. Download the key papers and set them aside. Then go to the websites of the key researchers and see where they've published recently.
  • The third step is to go to the website for these top conferences and look through their recent proceedings. Identify recent high-quality related work quickly. These papers, along with the ones you set aside earlier, constitute the first version of your survey. Make two passes through these papers. 

The paper also mentioned some related references:
A website that covers the entire spectrum of research skills [2].
If you are reading a paper to do a review, you should also read [3]. 
If you're planning to write a technical paper, you should refer both to [4] and [5]. 

Also, a downloadable `review matrix' that simplifies paper reviewing using the three-pass approach for papers in experimental psychology [6].

Prepare for the coming of Era of BIG DATA


“Big Data” is a popular topic that has been gaining attention from the high-performance computing niche of the information technology market. Big Data is an enormous amount of data from which it is extremely difficult to manage and glean information. Big Data provides both challenges and opportunities for quantitative analysts to develop improved predictive and descriptive models [1].


SAS launched SAS High-Performance Data Mining in December 2011 to enable you to analyze more data faster than ever before possible. Based on the SAS High-Performance Analytics model for distributed in-memory processing, SAS High-Performance Data Mining is delivered SAS software that uses Teradata or EMC Greenplum hardware. A subset of SAS High-Performance Analytics, SAS High-Performance Data Mining has truly revolutionized the model building and model-scoring processes. The massively parallel in-memory algorithms enable organizations to derive highly accurate and timely data mining models in minutes, not hours or days, to make better-informed business decisions [1].

SAS has developed many HP procedures, such as,


  • HPDMDB Summarize data
  • HPDS2 Parallel execution of DS2
  • HPFOREST Random forest
  • HPLOGISTIC Logistic regression
  • HPNEURAL Neural network modeling
  • HPNLIN Nonlinear regression
  • HPREDUCE Unsupervised variable selection
  • HPREG Regression
  • HPBIN Variable Binning
  • HPSAMPLE Sampling and data partitioning
  • HPIMPUTE Imputation
  • HPSEVERITY Severity models
  • HPCOUNTREG Regression of count variables
  • HPSUMMARY Summarize data
  • HPLMIXED Mixed linear models
  • HPATEST Test operational status of system



Hopefully, these procedures will be available in the late 2013, and will be available to academic field too.

U.S. and California Pursue Coordinated Care for Dual Eligibles: What's Next for Cal-MediConnect?


You may always wonder what is the future for Dual Eligibles under the Affordable Care Act. Is it too good to be true or eventually doing harm to the benefits of Medicare benefits? We may seek answer from the series of lectures/seminars from the UCLA health forum on April 24, 2013.  

The UCLA Jonathan and Karin Fielding School of Public Health is pleased to host The Health Forum at UCLA (FSPH), a series of regularly scheduled free public programs featuring health leaders discussing critical issues in public health.

 
"U.S. and California Pursue Coordinated Care for Dual Eligibles:
What's Next for Cal-MediConnect?"
California has over 450,000 people eligible for both Medicare and Medi-Cal coverage, also known as "dual eligibles." Dual eligible beneficiaries face difficulties navigating a currently fragmented medical system to find the services they need to treat serious and chronic medical conditions. Recently, California received Federal approval for a three-year demonstration program, Cal-MediConnect, to improve coordinated health care delivery and quality of services to dual eligibles which will be integrated in eight counties, including Los Angeles County. In this health forum we will discuss what changes in health service delivery dual eligibles should expect to see in managed care plans and network delivery systems.
When: This Wednesday, April 24th, 6:00-8:00pm
            6:00-6:30pm: Coffee and Reception
            6:30-7:15pm: Panel Presentations
            7:15-8:00pm: Question and Answer Session
 
Where: Neuroscience Research Building Auditorium, UCLA 
             635 Charles E. Young Drive South, Los Angeles
 
Panelists include: 
Richard Chambers

Seminar Series: The Future of Private Medical Practice


 
"The Future of Private Medical Practice"
The number of private medical practices is decreasing as more and more physicians choose to leave their practices to join larger health care systems. Playing a role in this shift are low government reimbursements, costly technological improvements and health care reform initiatives designed to encourage coordinated care. In this health forum we will discuss what's next for private medical practices and how it will impact the doctor-patient relationship.
When: Wednesday, February 27th, 6:00-8:00pm
            6:00-6:30pm: Coffee and Reception
            6:30-7:15pm: Panel Presentations

"How Will the Mental Health System Change 
Under the Affordable Care Act?"
More than 40 million children and adults in the United States live with mental illness. The Affordable Care Act will require coverage for individuals with these illnesses and extend benefits to at least 10 million previously uninsured Americans suffering from mental disorders. How will the health system, which is already straining to provide adequate treatment, provide quality mental health services to this greatly expanded pool of patients? In this health forum we will discuss what is being done around the country and across California to adapt our mental health system.
