A survey to investigate the association of pain, foot disability and quality of life with corns
No full textBackground
Corns are a common foot problem affecting a large proportion of the population. This study describes the characteristics of corns experienced by 201 participants taking part in a randomised controlled trial to investigate associations between demographic and corn parameters on pain, foot related disability and quality of life (QoL).
Methods
Pain from the main (index) corn was measured using a visual analogue scale (VAS); foot related disability was assessed with the Foot Disability Questionnaire (now known as the Manchester Foot Pain and Disability Index) and quality of life was recorded with the EQ-5D questionnaire. The effect of demographic and corn parameters on the pain and quality of life outcomes was assessed with analysis of variance (ANOVA) methods. The effect of the same factors on a linear combination of the foot-related disability outcome measures was assessed using multivariate ANOVA methods. Pain was also tested for its mediating properties on the causal pathway between the independent variables and quality of life.
Results
The mean pain score was 5.29 points on a 10 cm VAS, with females reporting substantively higher pain levels than males. Age affected foot-related disability, with lower levels on all domains of the MFPDI reported in older participants; each year of advancing age was associated with falls of: 0.009 points on the Concern about Appearance (CA) domain; 0.047 points on the Functional Limitation (FL) domain and 0.048 points on the Pain Intensity (PI) domain. Sex and corn type also affected disability, with higher scores reported by females and participants with plantar corns.
Conclusions
The effect of pain was shown to mediate the relationship between sex and foot-related disability. The presence of plantar corns has a more detrimental effect on QoL than dorsal/inter-digital corns
Specialty Corns
No full textAll parts of the com plant, including the grain, display tremendous diversity in morphology, color, composition, and physical properties. This diversity provides opportunity to add value to com by selecting particular traits that are well-suited for specific end uses. Some end users take advantage of this opportunity by contracting with producers to grow specific varieties in return for a premium price. In spite of this potential incentive, the majority of grain produced in the United States continues to fall into the category of "commodity com." It is marketed in domestic and world grain channels on the basis of mass or volume in a merchandizing system regulated by uniform grades and standards. It is not targeted to a specific end use, rather to a general market. "Specialty com," on the other hand, will be defined in this chapter as
any com that is improved for a specific end use compared to commodity com. The reader is referred to the book Specialty Corns (Hallauer, 2000) for a treatment of this subject in greater depth.This chapter is published as Scott, P., Pratt, R.C., Hoffman, N., Montgomery R. (2018). Specialty Corns in Corn Chemistry and Technology (3rd ed.), Serna-Saldivar, S., ed. Elsevier, AACCI, pp.289-303
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
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
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

Analysis of Dry Matter Accumulation Using Some Mathematical Growth Models in Silage and Seed Corns
No full textThis study was carried out at Bahri Dagdas International Agricultural Research Institute's experimental areas. C 955 and DK 585 were used as material. Richards, Gaussian and Logistic growth models were used for describing plants growth. Coefficient of determination (R-2), mean squared error (MSE), model efficiency (ME), mean rational error (MRE), mean squared variation (MSV) and Bias were used as comparison criteria. As results, Richards model described dry matter accumulation of silage and seeds corns better than Gaussian and Logistic growth models. Logistic growth equation described dry matter accumulation of silage and seeds corns worse than others growth.Bu araştırma Bahri Dağdaş Uluslararası Tarımsal Araştırma Enstitüsü deneme arazilerinde yürütülmüştür.

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
