Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Square Dancing with the Stars to Enhance Dynamic Hirschman Linkages?
No full textIn this Presidential Address, the author takes the reader on a reconnaissance of his life and time as a regional scientist. He points out scenery he found scintillating along the way, hoping that some may pick up the banner and chew on a few of the ideas for a while. He suggests a revisit to Albert O. Hirschman’s notion of key sectors and more empirical analysis related to Marcus Berliant’s and Masahisa Fujita’s notion of knowledge creation and transfer.Presidential Address, San Antonio, Texas, March 29, 2014 (53rd Meetings of the Southern Regional Science Association
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

A Comparative Clinical study on Open Versus Laparoscopic (TEP/TAPP) Inguinal Hernia Repair Techniques
No full textINTRODUCTION:
Hernia is defined as a protrusion of a viscus or a part of a viscus through an abnormal opening in the walls of its containing cavity. It is derived from the latin word 'hernios' meaning rupture. Most commonly seen in the inguinal region followed by paraumbilical/incisional hernia.
Inguinal hernia occurs in about 15% of adult population and inguinal hernia repair is one of the mostc ommonly performed surgical procedure.
In the era of minimal invasive surgery, hernia repair has seen a paradigm shift from open to laparoscopic technique. Evolution in the treatment of inguinal hernias has equalled to the technological developments in this field. The most significant advances to impact inguinal hernia repair have
been the addition of prosthetic materials to conventional tissue repairs. The laparoscopic inguinal hernia repair includes Totally Extraperitoneal approach (TEP)/Trans Abdominal Preperitonealapproach (TAPP).
Over 60 randomized trials have compared laparoscopic surgery
with Lichenstein repair. Following introduction of mesh for hernia repair, newer measures focus on post hernioplasty pain syndrome, quality of life and return to normal activities. They show although laparoscopic operation takes longer to perform, proven advantages are reduced pain both following surgery, more rapid return to full activity and reduced chance of wound complications.
A repair that results in an asymptomatic recurrence will not as clinically significant as a repair that imparts a significant amount of chronic pain, but does not lead to recurrence.
AIM OF THE STUDY:
The aim of this study is to prospectively compare the results of open mesh technique and laparoscopic repair for inguinal hernia and to compare operative time, post operative pain, length of hospital stay, return to normal activities and its complications.
MATERIALS AND METHODS:
STUDY DESIGN:
Prospective study.
STUDY POPULATION:
Patients – male and female presenting with inguinal hernia.
SAMPLE SIZE:
In this prospective study a total of 50 patients with inguinal hernia were enrolled into two comparative groups ,namely Lichtenstein’s and laparoscopichernia repair.
INCLUSION CRITERIA:
• All male and female patients with inguinal hernia consented for inguinal hernia repair.
• Incomplete hernia.
• Recurrent hernia.
EXCLUSION CRITERIA:
• Age >80 years.
• Age<12 years.
• Pregnancy.
• Scrotal abdomen.
• Obstructed hernia.
• Medically unfit patients (chronic asthma, COPD, Cardiac diseases).
CONCLUSION:
Laparoscopic hernia repair is safe and provide less postoperative morbidity in experienced hands and definitely had many advantages over open repair such as early resumption of daily activities and work, better subjective and objective cosmetic results with some limitations like more operative time.For bilateral and recurrent inguinal hernias laparoscopic approach is recommended. From the results of this study we find the outcomes of laparoscopic inguinal hernia are comparable with open repair. Laparoscopic repair has an advantage of less post operative pain, decreased hospital stay, faster recovery and improved cosmesis. It may soon become the procedure of choice not only for bilateral and recurrent hernias but also for primary, unilateral hernias.
The open repair has a definite advantage over laparoscopic repairfinancially; however the decreased hospital stay and faster recovery mayreduce the economic burden of laparoscopic surgery to some extent. The openrepair remains a good option especially for older, high risk patients and easy toperform, inexpensive and can be done under local anesthesia. However, the trend in surgery today is of minimally invasive surgery and rightfullyso as our study proves
