FDI Workshop on Zotero

On Wednesday, March 23 from 10:00 a.m.-12:00 p.m., the Faculty Development Institute will host a workshop on Zotero.  Zotero, a free, browser-based bibliographic manager, has gained quite a lot of popularity over the past year, and more students, researchers, and faculty members are using it as an alternative to other bibliographic managers like EndNote.

You can register online, just as you usually do for FDI sessions:  https://app.fdi.vt.edu/public/modules/selfenroll/_enroll.php?eventPk1=13162

If you can't make the FDI session, but would like to learn more about Zotero, or any other bibliographic manager, simply contact me and we can sit down and discuss it!

Book Review: The Volumetrics Eating Plan, by Barbara Rolls


Rolls, B. J. (2007). The volumetrics eating plan: Techniques and recipes for feeling full on fewer calories. New York: Harper




Reviewed by Paul J. Blalock, Virginia Tech Dietetic Intern




Introduction
Fad diets are a huge industry promising quick and easy weight loss with several new books offered every year.  According to the author of “The Volumetrics Eating Plan”, this is the exact opposite of a fad diet book stating that weight loss is hard work and the weight should come off slowly.  The premises of the book is eating low density foods that weigh more and will help keep a person feeling full longer than a small amount of a high density food.  Sound weight loss advice of burning more calories than one takes in, losing weight at a steady rate of one to two pounds per week, and eliminating forbidden foods.  The author simplifies reading food labels, makes weekly menu plans, and offers an abundant amount of easy to follow recipes with nutrition information.  The book encourages eating a variety of healthy food sources including unsaturated fats, fruits, vegetables, whole grains, low-fat dairy, and lean meats. It explains the health benefits of a healthy diet to any person able to read and likes looking at pictures.

Critical Analysis
“The Volumetrics Eating Plan” is a teaching tool for nutrition and a great cookbook.  The book explains nutrition based upon sound organizations such as the “American Institute for Cancer Research” and the “American Dietetic Association”.   Recipes use less nutrient dense foods by adding fruits, vegetables, and lentils to bulk up the meal with slow to digest fiber.  Other key recipe suggestions involve lower fat versions of dairy products, portion control, and lean meats.
The explanation of weight loss and a healthy weight uses widely accepted standards.  The book explains that one pound is equal to 3,500 calories and a healthy weight according to body mass index (BMI).  An explanation for the weakness of using BMI on very fit muscular individuals is included.  The book promotes using waistlines as a marker of weight loss progress as well as the health consequences of storing body fat in the mid section. 

The book adequately addresses establishing of behavioral goals.  The main components the author uses to make goals are specific, realistic, and forgiving.  From a psychological perspective, it is great to help the person losing weight to not create more thoughts that are self-defeating if a goal is not reached that day.  The book does describe the timing of weight loss, but timing needs to be included in the section, setting behavioral goals.  Sustainability is the best strength that the book emphasizes throughout the weight loss process including weight maintenance.

The Volumetrics Eating Plan is an excellent resource for anyone wanting to learn about how to lose weight while finding meals that will help keep you feeling full.  The advice offered uses a variety of sound organizations and offers a weight loss plan that is sustainable.  The author mentions the biggest hurdle is maintaining weight since the number on the scale is no longer going down.  It creates a lifelong healthy program to follow.  A huge benefit of this book is making the health benefits, nutrition, and activity level pieces fit together in an easy to understand way.

Happy National Registered Dietitian Day! A Culinary History Highlight.

I nearly forgot to wish you all a Happy National Registered Dietitian Day!  More information about the American Dietetic Association's National RD Day can be found here:  http://www.eatright.org/NNM/content.aspx?id=5189, but I wanted to make sure I mentioned it here, as well!

To celebrate National RD Day, I am highlighting an item from our Culinary History Collection, the 1886 A Manual of Dietetics, written by J. Milner Fothergill:

Note the quote on this page:  "What is one man's food is another man's poison." 
My favorite part in this item may be the preface, which proclaims that "the day of Dietetics has arrived!"  I imagine that the modern "day of Dietetics" is quite different from that of 1886, and encourage you all to drop by Special Collections to take a look at this jewel!  Of course, you can also view the entire book digitized, online:  http://scholar.lib.vt.edu/digital_books/pdf/RM218.5.F67_1886.pdf

And, once again, Happy National Registered Dietitian Day!  

FARQ: Using Impact Factors?

I just realized that I haven't done a Frequently Asked Reference Questions post since last December!  It's high time that I highlight a reference question that I've received a lot lately:

What are impact factors?  How do I locate them?  How do I use them?  

Definition:  Impact factors.  The name seems explanatory, but the entire concept and definition remains mysterious and vague to a lot of researchers.  Essentially, the impact factor represents a metric that measures the relative influence and significance of a journal within its particular discipline.  

How they are calculated:  Impact factors are calculated through a very specific formula:  Cites to recent items (previous two years of a journal's publications) divided by the Number of recent items (past two years)

Where they are located:  Not all journals receive impact factors, since only journals indexed in Journal Citation Reports receive an impact factor.  Journal Citation Reports is published by Thomson Reuters, which also owns and publishes ISI Web of Science, where you can also connect to information about a journal and its impact factor.  

I've created two short (each about a minute), silent screencasts to show you each of these two methods.  To enlarge the screencast, click on the little square icon with the circle in the middle.  If you're reading this in any sort of blog reader, you'll need to click through to see the screencasts.

Using JCR to locate impact factors

Using Web of Science to locate impact factors

How and why to use them:  Impact factors are used to determine the most influential journals in a particular field.  You may want to locate these journals for a number of reasons:  1) to find research from the most authoritative journals and 2) to submit your research for publication to the most influential/widely read journals.

Many researchers also use the impact factor as a metric for promotion and tenure assessment.  Although impact factors may not be a good sole indicator of a researcher's impact (see criticisms below), this metric can still provide helpful information during the tenure and review process.

Criticisms:  Many researchers feel that the impact factor is an inadequate or inappropriate method for assessing a journal's significance or impact.  Criticism of the impact factor usually revolves around several different reasons:  1) that IF represents an arithmetic mean, rather than a normal distribution; 2) that different disciplines may have different representation in JCR, or exhibit different readership and research patterns, which could affect the rate of citations; 3) that journals can manipulate their editorial policies to include more review articles (more highly cited) or fewer citable items (a better ratio); 4) that impact factor still includes an author's self-cites.

Regardless of the criticisms, impact factor remains the most widely used assessment metric for journals.  Other, alternative assessment metrics include:  H-Index (more author based), Eigenfactor, or the Google Scholar Citation Counter.

Book Review: Switch, by Chip and Dan Heath

In addition to soliciting student contributions for National Nutrition Month, I've also asked the Virginia Tech Dietetic Interns to contribute book reviews to this blog.  These book reviews will feature books owned by University Libraries and available for checkout here at Newman Library that are relevant to nutrition and other health professionals!  A side note:  half of our dietetic interns are actually in Northern Virginia (not in Blacksburg), so if any Northern Virginia folks are interested in checking out any of the books reviewed here, remember that you can use our Interlibrary Loan service to have books from Newman delivered to you up there!


Without further ado...our first book review!  Click the link below to view the Addison record for this book.



Heath, C., & Heath, D. (2010). Switch: How to change things when change is hard. New York: Broadway Books.  


Reviewed by Danielle Osborne, Virginia Tech Dietetic Intern


Ever taken a ride on an elephant? Imagine what would have happened if the elephant had its own idea of where it wanted to go. Would you, the rider, have any chance of re-directing the vast elephant? Reading Switch by brothers Chip Heath and Dan Heath will provide a thorough answer to this question. Written for the lay audience, Switch has a casual, conversational tone that engages the reader as it uses the analogy of an elephant and a rider to explain the psychology behind change.   

The book starts with the section “Direct the Rider” which delves into a discussion on the rational part of each person’s mind, which the authors call the rider. They suggest using the logical, reason-based section of the brain to find what works in a situation in order to mimic and spread that success, to find specific, small behaviors to focus on, and to define the goal of change. This is followed by a group of chapters on “Motivating the Elephant”.  The elephant represents the emotional, and more influential, part of the mind. The Heath brothers suggest finding the feeling behind change in order to inspire it, to break the change down into manageable pieces, and to help foster an identity in others that will enable change. Finally, the book discusses how to “Shape the Path” by making changes to alter the environment surrounding the logical and emotional person in order to support change. Detailed examples of success stories are scattered throughout the pages, as are numerous references to recent research and sections that provide ways for the reader to apply the book through brain-storming and problem-solving sessions. With its numerous examples from a wide variety of fields, readers will likely find Switch quite relevant to their lives.

Switch includes references to research and evidence from its first page through its last (294 pages in all, including notes). For instance, the opening paragraph cites a study conducted at a movie theater on popcorn consumption. When compared to the origin of the citation, the authors were found to have accurately shared the results of the study. Later in the book, a reference to a 1968 study by Latane and Darley on the effects that bystanders have on an individual’s response to an emergency was made. The original research in this instance also matched the quoted material in Switch. This reveals one of the strengths of Switch; it includes extensive references to solid research and evidence in support of the authors’ theory. The book includes 254 notes for its eleven chapters, many of which reference studies or other forms of evidence. Another strength of Switch comes from its hands-on approach. Throughout the text, sections are set aside to provide a break for the reader to apply what has just been explained. The sections include examples which allow the reader to apply problem-solving and critical thinking skills to brain storm a solution, using the tactics provided by Switch.  The authors walk step by step through the examples as well, providing further insight into the process of inspiring change. Finally, Switch flows well as the three sections build upon one another in an organized manner to develop the authors’ idea.

Possible weaknesses of Switch include its assumption that the elephant/rider approach to change will work in all situations. Though the book certainly provides a number of success stories, it may be naïve to think the approach could never go awry. In spite of this, Switch still provides a unique approach to facilitating change, one that numerous studies and stories support. Also, though plentiful examples are both helpful to understanding the ideas presented and to facilitate application of the information, the book could be condensed and still remain effective. Even if a reader can only read half of Switch, useful insight into the psychology behind change will be gained.

As a newly published book, Switch has come at a needed time. With a push for change in the public sector, including in America’s current food and exercise culture, this book can provide useful insight and guidance. For those who apply what they learn about the elephant and rider, Switch has the potential to inspire lasting change.
