Mass Exodus: Examination of USAF Pilot Retention
No full textEvery organization faces challenges throughout its existence due to an ever changing world. These trials can range from small internal problems all the way to large issues impacting the organization’s very foundation. Either way, these challenges must be examined, understood, and appropriately dealt with for the organization to survive. The United States Air Force (USAF) is currently facing such a challenge in the form of severely low retention among its highly trained pilots. This study strove to explore this problem, looking at the underlying reasons why pilots were leaving the USAF before retirement and then generating potential evidence based solutions to this retention issue. In order to accomplish this goal, the researcher utilized a grounded theory methodology, examining the interview responses of twenty-one former USAF pilots regarding their retention decisions and experiences in the USAF. After analysis, the data gathered showed that quality of life factors, such as work/life balance and outside opportunity, had the greatest impact on retention decisions and led to the development of the USAF pilot quality of life retention theory. Additionally, the data provided a foundation for the creation of two solution sets, one focused on improving quality of life factors for USAF pilots and the other centered around improving leadership within the USAF, due to leadership’s impact on almost every aspect of a service member’s life and career. The end goal is not just a better understanding of why this problem became so dire in the first place, but also what can be done to alleviate the strain and ensure that the chances of such a retention problem happening again are low.|Keywords: Retention, Work/life balance, Leadership,ProQuest Traditional Publishing Optio

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

No full textAppropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
Comparison of uncertainty in per unit area estimates of aboveground biomass for two selected model sets
No full textUncertainty in above ground forest biomass (AGB) estimates at broad-scale depends primarily on three sources of error that interact and propagate: measurement error, model error, and sampling error. Using Monte Carlo simulations, we compare the total propagated error for two sets of regional-level component equations for lodgepole pine AGB, and for two sets of high-precision instruments by accounting for all three of these sources of error. The two sets of models compared included a set of newly-developed component ratio method (CRM) equations, and a set of component AGB equations currently used by the Forest Inventory and Analysis (FIA) unit of the United States Department of Agriculture (USDA) Forest Service. Relative contributions for measurement, model, and sampling error using the current regional equations were 5{\%}, 2{\%} and 93{\%}, respectively, and 13{\%}, 55{\%} and 32{\%}, respectively using the CRM equations. Relative standard error (RSE) values for the current regional and CRM equations with all three error types accounted for were 20.7{\%} and 36.8{\%}, respectively. Results for the model comparisons indicate that per acre estimates of AGB using the CRM equations are far less precise than those produced with the current set of regional equations. Results for the instrument comparisons indicate the terrestrial lidar scanning reduce uncertainty in broad-scale estimates of AGB attributed to measurement error
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
