MeSH term explosion and author rank improve expert recommendations
No full textInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank
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
"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.
Hinders for Eco-friendly Media Selection
No full textThis study shows that, despite organizations claiming to care for the green environment through documented environmental policies, marketing communication such as advertising media selection does not seem to be much guided by green environmental concerns. Problems with consistency and control thus seem to exist between companies’ ideas/decisions (documented environmental policies) and their actions (advertising media selection), causing the need for justification and/or hypocrisy. This study adds to prior research on the non-use of models in practice by showing that the non-use of models also exists among marketing managers when selecting advertising media for marketing communication purposes. It was found that 64 percent of the marketing managers do not make use of media selection models. In the attempt to investigate differences in the factors guiding media selection between marketing managers who use media selection models (users) and those who do not use any model (non-users), it was found that the users take a medium’s eco-friendly characteristics less into consideration than the non-users. The paper discusses that the use of models can be viewed as attempts for making more rational decisions. The findings thus suggest that rational decision-making (users) may hinder eco-friendly media selection while non-rationality (non-users) may develop more powerful organizational ideologies such as acting responsibly towards the green environment. However, this study points out a link between the use of media selection models, previous experience and rules of thumb, i.e. the users tend to make more use of previous experience and rules of thumb than the non-users. Thus, the author argues that a new approach to model use may be needed and that the media selection should not be too much influenced by the marketing managers’ previous experience and rules of thumb. Otherwise, new factors may be overlooked such as consumers’ increasing concern for the green environment in relation to consumer advertising media attitudes. Previous studies have found that current approaches to marketing planning pay too little attention to the impact of technological advances on changes in consumer media habits. Thereby the risk may exist for focusing on mainly conventional media and not selecting “new media”. The present study seems to contradict these previous findings by showing that the selection of “new media” such as media using the Internet was found among the most selected advertising media by both the users and non-users for the two communication objectives studied, i.e. brand-building and to increase sales. Thus, the results indicate that while the marketing managers adapt their media selection to changes in technological media advances they tend to overlook consumers’ increasing concern for the green environment and the environmental aspect of advertising media. The results also show differences among the marketing managers in their selection of advertising media. At the same time as the non-users tend to be more precise with the recycling of paper, they are more inclined to select paper-based media such as catalogues and brochures than the users. The users on the other hand, tend to select more electronic media such as TV, radio and cinema than the non-users. In the attempt to explain the factors guiding media selection and in particular to what extent the environmental aspect of advertising media is considered, green environmental responsibility attitudes (GERA) of the users and non-users are assessed.Media Selection; Advertising; Green Environment; Marketing Managers; Models; Green Environmental Responsibility Attitude (GERA); Rationality; Non-rationality
Skin Disease and Vitamin D
No full textBackground There is a growing interest in the role of vitamin D beyond its effect on bone health. The vitamin D receptor is widely expressed in many different tissues, including the skin. Aim The aim was to investigate the association between 25-hydroxyvitamin D and cutaneous lupus erythematosus, and the effect of vitamin D on psoriasis. Two additional studies about the population prevalence of cutaneous lupus and the cardiovascular risk of psoriasis were undertaken. Methods Patients with cutaneous lupus were identified from multiple sources from both the hospital and the community. The database compiled was then used to clinically assess both the scarring and the activity of cutaneous lupus in association with 25-hydroxyvitamin D status. A randomised, placebo-controlled study of the effect of oral 100,000 IU monthly Vitamin D3 (cholecalciferol) was undertaken with participants who had psoriasis and had been recruited to a larger study called the Vitamin D assessment study. Results One hundred and forty-five patients with cutaneous lupus were identified. Māori and Pacific people were found to have a higher prevalence of all types of cutaneous lupus compared with the European population [relative risk 2.47 (95% CI: 1.67–3.67)] and especially discoid lupus [relative risk 5.96 (95% CI: 3.06–11.6)]. No relationship was found between cutaneous lupus (either active disease or scarring) and 25-hydroxyvitamin D levels. Sixty-five patients with mild psoriasis were recruited. The mean Psoriasis Area Severity Index was 3.0 and 3.3 in the placebo and active group respectively. No improvement in psoriasis was recorded by the addition of vitamin D3 when assessed by the Psoriasis Area Severity Index, Global Physician’s Assessment, Dermatology Life Quality Index or the Psoriasis Disability Index (p > 0.05). There was no increase in cardiovascular risk in the psoriasis participants (p > 0.05). Conclusions 25-hydroxyvitamin D status is not a significant factor for cutaneous lupus. Further research is needed to examine why Māori and Pacific peoples have high rates of cutaneous lupus. Oral vitamin D3 is not a therapeutic option for patients with mild psoriasis, and the low cardiovascular risk of a New Zealand patient cohort with mild psoriasis is confirmed
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
