No full textGabriela Mut-Vitcu,1 Bogdan Timar,2 Romulus Timar,1 Cristian Oancea,3 Ioan Cosmin Citu4 1Second Department of Internal Medicine, 2Department of Functional Sciences, 3Department of Infectious Diseases, 4Department of Obstetrics and Gynecology, “Victor Babes” University of Medicine and Pharmacy, Timisoara, Romania Purpose: To evaluate the prevalence of depression and its impact on the quality of diabetes-related self-care activities in elderly patients with type 2 diabetes. Patients and methods: In this cross-sectional study, 184 patients with type 2 diabetes were enrolled. Depression was evaluated using Patient Health Questionnaire-9 while the quality of diabetes-related self-care activities was assessed using the Summary of Diabetes-Related Self Care Activities Questionnaire. Results: In our study group, 53.3% of the patients had moderate depression, 17.9% had severe depression, and 28.8% had no depression symptoms. Patient’s age (P=0.024), presence of diabetic neuropathy (P<0.001), and body mass index (P=0.037) proved to be independent and significant predictors for developing depression in patients with type 2 diabetes. The severity of depression was reverse correlated with the quality of self-care activities for all the studied components: global score (r=-0.305), diet intervention score (r=-0.297), exercise score (r=-0.388), glycemic monitoring score (r=-0.055), and feet care score (r=-0.180). The presence of severe depression was associated with an increased prevalence of diabetes complications such as diabetic neuropathy and chronic kidney disease. Conclusion: The prevalence of depression is higher in patients with type 2 diabetes compared to general population. Depression has a major negative impact on the quality of diabetes-related self-care activities and, being a treatable condition, proactive screening followed in case of a positive diagnosis by adequate treatment should be performed in all patients with diabetes.

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
Proposed Indo-Aryan Etymology for Hurrian timer(i)/timar(i)
No full text


In Hurrian, timer(i)/timar(i) ‘dark’ appears exclusively in the phrase timerre eženi “the dark earth” (abl.-inst.). It has been suggested that this phrase and its reflexes in Hittite and Greek derive from the common religious trope of “the devouring earth” originating in northern Mesopotamia, with Hurrian providing the first attestation. However, the atypical morphology of the adjective, which cannot be derived from a noun and does not have the normal (C)VC root pattern of Hurrian, and the semantic field, with Hurrian having borrowed many words for colors, make a native Hurrian origin for timer(i)/timar(i) unlikely. It is suggested instead that the adjective, as well as its counterpart timiraš ‘a dark/black color (of an animal)’ in the Kassite language, was borrowed from Indo-Aryan *tam-[e]r, probably as a result of a shared Indo-Aryan cultural superstratrum. While no alternatives are offered, such an etymology calls into question a Hurrian origin for the religious concept of “devouring earth.”

"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
Factors influencing the quality of life perception in patients with type 2 diabetes mellitus

In all participants, the perception on the quality of life was measured using the quality of life index – diabetes version III proposed by Ferrans and Powers. We evaluated the impact of several anthropometric and diabetes-related (ie, diabetes history and quality of glycemic control) factors on the patient’s perception on the quality of life.Results: The presence of diabetes complications was associated with a decreased quality of life: retinopathy (1 vs 5 points; P<0.001), chronic kidney disease (-1 vs 5 points; P<0.001), and neuropathy (-1 vs 5 points; P<0.001). A significant reverse correlation was found between the patient’s quality of life and depression’s severity (Spearman’s r=-0.345; P<0.001) and body mass index (Spearman’s r=-0.158; P=0.026). A positive association between the quality of life and the quality of diabetes-related self-care activities was found (Spearman’s r=0.338; P<0.001). No significant association was found between the patient’s quality of life and the quality of glycemic control, diabetes duration, age, gender, or smoking status.Conclusion: To improve the patient’s quality of life, special care should be given to the modifiable diabetes-related factors: the prevention and treatment of diabetes complications, treatment of depression, and weight loss in obese and overweight patients. Keywords: quality of life, type 2 diabetes, diabetes complications, diabetes-related self-care activitie

In all patients, the adherence to DRSCA was evaluated using the Summary of Diabetes Self-Care Activities (SDSCA) questionnaire; a higher SDSCA score is associated with a better adherence. The presence and severity of neuropathy was assessed using the Michigan Neuropathy Screening Instrument (MNSI) and the severity of depression using the Patient Health Questionnaire-9 (PHQ-9).Results: The presence of neuropathy was associated with a decreased SDSCA score (26 points vs 37 points; P<0.001), an increased severe depression prevalence (24.7% vs 4.3%; P<0.001), and an increased PHQ-9 score (12 points vs 7 points; P<0.001). The MNSI score was reverse correlated with SDSCA score (r=-0.527; P<0.001) and positively correlated with PHQ-9 score (r=0.495; P<0.001). The reverse correlation between MNSI score and SDSCA score was present for all the subcomponents of SDSCA questionnaire (diet, exercise, glycemic monitoring, and foot care).Conclusion: The presence of neuropathy is associated with decreases in the quality of adherence to DRSCA in patients with T2DM and with increases in the symptomatology of depression. The significant, negative association between the severity of T2DM and the quality of disease self-management points to a possible loop-type relationship between these two components, being possible a reciprocal augmentation with negative consequences on the global management of the disease.

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
