Urban Chickens as a Pathway for Human Illness? An Examination of Knowledge, Behavior, and Risk
Authors: Capoccia Stella , Masters Michael , Risser Scott
Published: March 2018

This research investigates the relationship among human knowledge, behavior, and risk as they relate to urban chicken husbandry in the U.S. Concern over zoonotic diseases has been on the rise, especially with increasing contact. In particular, avian influenza, or bird flu, Salmonella enterica (salmonella), and Escherichia coli (E. coli), can all cross species lines between people and poultry. This study analyzed knowledge and practices in urban chicken husbandry to assess how they relate to risk of disease acquisition, hypothesizing that certain practices associated with a lessened knowledge base may heighten the risk. This study used social surveys to examine the self-reported knowledge base of individuals involved in chicken husbandry as they relate to beliefs and behaviors associated with the care of these animals. These results identify key factors that may heighten the risk of disease transmission, and demonstrate that an increased knowledge base could act to lessen this risk.
Responses of hydrological model equifinality, uncertainty, and performance to multi-objective parameter calibration
Authors: Her Younggu , Seong Chounghyun
Published: March 2018

Multi-objective calibration can help identify parameter sets that represent a hydrological system and enable further constraining of the parameter space. Multi-objective calibration is expected to be more frequently utilized, along with the advances in optimization algorithms and computing resources. However, the impact of the number of objective functions on modeling outputs is still unclear, and the adequate number of objective functions remains an open question. We investigated the responses of model performance, equifinality, and uncertainty to the number of objective functions incorporated in a hierarchical and sequential manner in parameter calibration. The Hydrological Simulation Program – FORTRAN (HSPF) models that were prepared for bacteria total maximum daily load (TMDL) development served as a mathematical representation to simulate the hydrological processes of three watersheds located in Virginia, and the Expert System for Calibration of HSPF (HSPEXP) statistics were employed as objective functions in parameter calibration experiments. Results showed that the amount of equifinality and output uncertainty overall decreased while the model performance was maintained as the number of objective functions increased sequentially. However, there was no further significant improvement in the equifinality and uncertainty when including more than four objective functions. This study demonstrated that the introduction of an adequate number of objective functions could improve the quality of calibration without requiring additional observations.
Degradation of azo dye by bacterium, Alishewanella sp. CBL-2 isolated from industrial effluent and its potential use in decontamination of wastewater
Authors: Ajaz Mehvish , Elahi Amina , Rehman Abdul
Published: March 2018

In the present study, Alishewanella sp. CBL-2 was characterized on the basis of biochemical and 16S rRNA sequencing. The bacterium was found to decolorize 83% Sumifex Tourqi blue within a period of 6 days at 37 °C and pH 7. The predominant form of the enzyme was found to be extracellular (78%) as compared to intracellular (16%). The breakdown of azo bond was confirmed through thin layer chromatography (TLC) analysis as new bands and peaks were observed in chromatograms of extracted metabolites of decolorized samples. Growth of beneficial microbial fauna in the presence of bacterial decolorized wastewater indicates that this wastewater is safe for the survival of microorganisms. High bioremediation potential makes Alishewanella sp. CBL-2 an impending foundation for green chemistry to remove azo dyes from industrial wastewater.
Interrupting the FGF19-FGFR4 Axis to Therapeutically Disrupt Cancer Progression
Authors: Lang Liwei , Shull Austin Y. , Teng Yong
Published: March 2018

Coordination between the amplification of the fibroblast growth factor FGF19, overexpression of its corresponding receptor FGFR4, and hyperactivation of the downstream transmembrane enzyme β-klotho has been found to play pivotal roles in mediating tumor development and progression. Aberrant FGF19-FGFR4 signaling has been implicated in driving specific tumorigenic events including cancer cell proliferation, apoptosis resistance, and metastasis by activating a myriad of downstream signaling cascades. As an attractive target, several strategies implemented to disrupt the FGF19-FGFR4 axis have been developed in recent years, and FGF19-FGFR4 binding inhibitors are being intensely evaluated for their clinical use in treating FGF19-FGFR4 implicated cancers. Based on the established work, this review aims to detail how the FGF19-FGFR4 signaling pathway plays a vital role in cancer progression and why disrupting communication between FGF19 and FGFR4 serves as a promising therapeutic strategy for disrupting cancer progression.

AbstractLight emission from ZnMnTe/ZnMgTe structures with the quantum wells ZnTe containing monolayer manganese inclusions and quantum wells Zn_0.45Mn_0.15Te were investigated under the different excitation conditions. The heavy-hole exciton σ^+ and σ^– magnetic components show the unusual behavior concerning their energy shifts and intensities. It is possible to explain the Zeeman splitting of the heavy exciton emission band if the following factors are taken into account. Firstly, ZnMnTe/ZnMgTe quantum well structures are of the type II due to the strains as concerns to the electron and heavy hole. Secondly, the electron and hole magnetic sublevels population is far from equilibrium due to the fast energy transfer from the electron- hole system to the 3 d -shells of magnetic ions.

The electronic density of states has been analyzed. An optical conductivity spectrum has been calculated for GdCuGe; it reveals specific features that are analogous to the ones discovered previously in the GdCuSi compound with a similar hexagonal structure.
Emancipação humana e educação: perspectivas para uma formação escolar
Authors: Lima Fernanda Bartoly Gonçalves de , Silva Kátia Augusta Curado Pinheiro Cordeiro
Published: March 2018

O presente trabalho pretende discutir os limites e as possibilidades de a educação escolar corroborar com uma formação que se alinhe com a proposta de emancipação humana. Para isso, se realiza uma análise bibliográfica, na perspectiva do materialismo histórico dialético, de obras clássicas de Marx e Engels, além de obras de autores marxistas que discorrem sobre a questão da formação humana. Buscando esclarecer a concepção de emancipação na perspectiva marxiana, retoma-se a compreensão de ontologia humana, com base em categorias marxianas que explicam a constituição do ser social. Nessa perspectiva, as possibilidades de emancipação se encontram na capacidade do homem transformar o mundo a sua volta, o que rechaça as expectativas de emancipação sem se alterar a realidade social. Neste sentido, a educação escolar não poderia, diretamente, realizar a emancipação da humanidade, mas se configura como uma importante superestrutura para este fim, quando se considera sua potencialidade para a promoção da apropriação do conhecimento humano, em sua compreensão histórica radical, se posicionando pela perspectiva da classe proletária.

Authors: Zanforlin Sofia Cavalcanti
Published: March 2018

O artigo realiza um estudo de caso da campanha Meu Amigo Refugiado lançada em dezembro de 2016 nas principais cidades do Brasil pela ONG Migraflix a partir da discussão do conceito de cosmopolitismo e do consumo cultural. A campanha consistiu na recepção por uma família brasileira a refugiados durante a ceia de Natal. Após a realização dos encontros, foram enviados, por e-mail, questionários para os refugiados participantes, como também para as famílias que os recepcionaram. A partir da análise das respostas percebemos que o engajamento à causa dos refugiados se traduz pelo apelo moral às atrocidades propagadas pela mídia como pela possibilidade de experiências cosmopolitas com estrangeiros possuidores de uma história pessoal de luta e superação.
Determinants of corporate cash holdings: An empirical study of Chinese listed firms
Authors: Ahmed Rizwan , Qi Wu , Ullah Subhan , Kimani Danson
Published: March 2018

This study explores the determinants of corporate cash holdings in the Chinese context. As one of the largest developing countries in the world, China offers an interesting opportunity to explore the role of corporate governance, and ownership structure in explaining corporate cash holdings. Owing to the unique economic problems in the developing and emerging economies, this study aims to investigate whether the research findings on developed countries could be generalized globally. Applying fixed-effects estimations on a sample of 115 Chinese firms listed between 2012 and 2016, we find that the level of corporate cash holdings has a significantly negative relationship with leverage, bank debt, non-cash liquid assets and managerial ownership. In particular, cash flow volatility, investment opportunity and dividend have a significantly positive relationship with cash holdings levels. These findings are consistent with the majority of the existing studies carried out in the Western context. We also find that firm size, cash flow, board independence and ownership concentration have a significant influence on the level of corporate cash holdings. Our study contributes to the finance literature and we offer new insights into the relationship between corporate governance and corporate cash holdings in the Chinese context. Some of the findings on the developed countries could be generalized to a wider context. Further, the unique relationship between corporate governance and cash holdings in the Chinese context provides empirical insights for further research.

Published: March 2018

If you haven’t measured something, you really don’t know much about it. —Karl Pearson (attributed)

Gastrointestinal (GI) symptoms represent an important and often unappreciated cause of morbidity in diabetes, although the significance of this burden across the spectrum of patients and the underlying pathophysiology, including the relationship of symptoms with glycemic control, remain poorly defined. The relevance of GI symptoms and the necessity for their accurate assessment have increased with the greater focus on the gut as a therapeutic target for glucose lowering. This review addresses the prevalence, assessment, pathogenesis, and management of GI symptoms in diabetes, beginning with broad principles and then focusing on specific segments of the GI tract. We initially performed a literature search of PubMed by using synonyms and combinations of the following search terms: “gastrointestinal symptoms”, “diabetes”, “prevalence”, “pathogenesis”, “diagnosis”, and “management”. We restricted the search results to English only. Review papers and meta-analyses are presented as the highest level of evidence where possible followed by randomized controlled trials, uncontrolled trials, retrospective and observational data, and expert opinion.
Current Challenges and Opportunities in the Prevention and Management of Diabetic Foot Ulcers
Authors: Jeffcoate William J. , Vileikyte Loretta , Boyko Edward J. , Armstrong David G. , Boulton Andrew J.M.
Published: March 2018

Diabetic foot ulcers remain a major health care problem. They are common, result in considerable suffering, frequently recur, and are associated with high mortality, as well as considerable health care costs. While national and international guidance exists, the evidence base for much of routine clinical care is thin. It follows that many aspects of the structure and delivery of care are susceptible to the beliefs and opinion of individuals. It is probable that this contributes to the geographic variation in outcome that has been documented in a number of countries. This article considers these issues in depth and emphasizes the urgent need to improve the design and conduct of clinical trials in this field, as well as to undertake systematic comparison of the results of routine care in different health economies. There is strong suggestive evidence to indicate that appropriate changes in the relevant care pathways can result in a prompt improvement in clinical outcomes.
A misericórdia e a libertação na literatura joanina: uma análise ricoeuriana no horizonte da teologia fundamental
Authors: Xavier Donizete José
Published: March 2018

Este trabalho diz respeito à ideia da misericórdia e da libertação presentes na literatura joanina. Pautando-nos na figura de Maria de Magdala em sua busca de Jesus (Jo 20,1.11 ss) e no reconhecimento da voz do seu mestre que a impulsiona a seguí-lo (Jo 10,4), pretende-se analisar à luz da hermenêutica de Paul Ricoeur, no horizonte da teologia fundamental, a misericórdia como forma de reconhecimento do outro e a libertação como forma de dar presença a este outro. Tomando por princípio hermenêutico que os textos bíblicos podem encontrar lugar na reflexão filosófica e que esta pode apresentar-se como organon à reexão teológica, este artigo defende a importância de falarmos da função poética da linguagem bíblica e o seu poder descortinador de um novo mundo. Ainda objetiva verificar que na literatura joanina, na figura de Maria de Magdala, metáfora da comunidade da nova aliança (Jo 20,16), a solicitude introduz um novo tipo de relação que torna possível estimar o si mesmo como outro e o outro como a si mesmo. Maria de Magdala, como nos propomos analisar, nos convida a acolher imaginativamente que a palavra Rabbouni/ Mestre que ecoa de sua boca é sinal da restauração anunciada (Jo 3,15).

The article explains about haidh, nifas and istihadhah according to Islamic view. Islam has a positive view on a woman who is undrgoing menstruation, nifas and istihadhah, because Islam very cares with woman reproduction health. None of the texts that consider woman who is undergoing the process of reproduction is as a dirty person and should be shunned. Likewise fiqh substantially negative view of women's reproductive process, although in some specific law product, fiqh does not reflect gender sensitivity. Real conditions of women should be the primary reference in all laws and regulations concerning menstrual problems, nifas and istihadhah. Reproductive rights of women are supposed to be guaranteed in any legal formulation. For ensure the reproductive rights of women equal to sustain human life and its descendants (hifdz annasl) which is one of the goals of Islamic Shariah (maqasid ash-shari'ah).

The Amomos in the Byzantine chant: a diachronical approach with emphasis on musical settings of the 19th and 20th centuries
Authors: Papatzalakis Dimos
Published: March 2018

The book of the Psalms constitutes the main source from where the Offices of the Orthodox church draw their stable parts. It has been diachronically one of the most used liturgical books of the cathedral and the monastic rite. In this paper we focus on the Psalm 118, which is well known under the designation “Amomos”. In the first part of our study we look for the origin of the book of the Psalms generally. Afterwards we present the Offices in which the Amomos is included, starting from the Byzantine era and the use of the Amomos in the cathedral and the monastic services. Then, we negotiate the question of its use in the post-Byzantine era. In the next section we quote the most important settings of the Byzantine, post-Byzantine and new-Byzantine composers in Constantinople, Smyrna and Thessaloniki, as well as some evidence of their lives and their musical works. In the next section we introduce some polyprismatic analyses for the verses of the first stanza of the Amomos, which are set to music in 19th and 20th centuries. After some comparative musicological analyses of the microform of the compositions or interpretations, we comment on the music structure of the settings of Amomos in their liturgical context. Our study concludes with some main observations, as well as a list of the basic sources used to write this paper.
Aspects of Musical Semantics from the Perspective of Structuralism, Semiotics and Narratology
Authors: BALAN MIHAELA-GEORGIANA
Published: March 2018

Music is a universal force, a widely spread mean of communication on the entire planet, because it has a strong ability to influence human emotions, even without words (when referring to instrumental or symphonic music). Thus, music is one of the most challenging arts in 'deciphering' the hidden message of its creator. The present paper is focused on three analytical techniques which imposed themselves in the musicology field of the 20th century – structuralism, semiotics, narratology. Our purpose is to offer a general outlook on these perspectives and some specific principles of applicability when approaching a musical score, in terms of formal construction, sonorous structures, equivalence classes applied to musical elements, energetic potential of musical isotopes using modal verbs, essential aspects in determining the narrative frame (spatiality, temporality, actoriality). Structuralism, semiotics and narratology emerged as independent sciences successively, during half a century, influencing each other in a stimulating coexistence which enabled a wide scientific opening until present.
Thermodynamic model for solution behavior and solid-liquid equilibrium in Na-Al(III)-Fe(III)-Cr(III)-Cl-H2O system at 25°C
Authors: André Laurent , Christov Christomir , Lassin Arnault , Azaroual Mohamed
Published: March 2018

The knowledge of the thermodynamic behavior of multicomponent aqueous electrolyte systems is of main interest in geo-, and environmental-sciences. The main objective of this study is the development of a high accuracy thermodynamic model for solution behavior, and highly soluble M(III)Cl3(s) (M= Al, Fe, Cr) minerals solubility in Na-Al(III)-Cr(III)-Fe(III)-Cl-H2O system at 25°C. Comprehensive thermodynamic models that accurately predict aluminium, chromium and iron aqueous chemistry and M(III) mineral solubilities as a function of pH, solution composition and concentration are critical for understanding many important geochemical and environmental processes involving these metals (e.g., mineral dissolution/alteration, rock formation, changes in rock permeability and fluid flow, soil formation, mass transport, toxic M(III) remediation). Such a model would also have many industrial applications (e.g., aluminium, chromium and iron production, and their corrosion, solve scaling problems in geothermal energy and oil production). Comparisons of solubility and activity calculations with the experimental data in binary and ternary systems indicate that model predictions are within the uncertainty of the data. Limitations of the model due to data insufficiencies are discussed. The solubility modeling approach, implemented to the Pitzer specific interaction equations is employed. The resulting parameterization was developed for the geochemical Pitzer formalism based PHREEQC database.

Seasonal activity of Leptoiulus trilineatus (C.L. Koch, 1847) and Megaphyllum trassylvanicum (Verhoeff, 1897) (Diplopoda: Julida: Julidae)
Authors: Bachvarova Darina , Doichinov Aleksandar , Abdulova Rayme
Published: March 2018

The article presents the results of a study of the soil surface seasonal activity of two species of julidae, widely spread in the Balkan Peninsula: Leptoiulus trilineatus (C.L. Koch, 1847) and Megaphyllum trassylvanicum (Verhoeff, 1897). The material was collected by means of pitfall traps between May 2007 and May 2009 in natural and urban habitats exposed to varying degrees of anthropogenic pressure. In the study period 1474 specimens of L. trilineatus and 618 specimens of M. transsylvanicum were collected. The impact of the soil and air temperature and humidity on the seasonal activity of both species was measured through statistical analysis. The statistical data processing was conducted using SPSS 9.0 and StatPlus 3.5.3 software packages.

L. trilineatus and M. trassylvanicum are polytopic, mesophilic and mesotermic species with year-round activity in the studied area. There is no statistically significant correlation between the degree of anthropogenic impact and the activity of the two species.

Leptoiulus trilineatus shows equal preference for both urban and natural habitats in the studied area. The species demonstrates the typical of all millipedes bimodal activity, which is the highest in spring and the beginning of winter – in the periods from March to May and from November to December. The coefficients of correlation dependence of L. trilineatus activity on the tested abiotic environmental factors are not statistically significant. The Pearson-Brave coefficient which measures the effect of soil humidity on species activity is 0.417, which shows a positive correlation. M. trassylvanicum has the highest frequency in urban biotops such as parks in the urban and suburban areas of Shumen and in the coniferous habitats on the Shumen Plateau. In this area the species demonstrates its highest activity in spring and summer (from February to July). The abiotic factors with statistically significant effect on the soil surface activity of M. trassylvanicum are the soil and air temperature – the values of the Pearson-Brave correlation coefficients are 0.708 and 0.586 respectively.

Published: March 2018

The method of heat protection and control of phenophases of fruit trees by means of a ring energy divider with insert in the zones of risky agriculture has been developed. This method is performed on the principle of a heat pipe (thermosyphon) or thermopile working in the device of a ring energy divider. The naturally circulating coolant can change the aggregate state, and the presence of a capillary porous structure in the ring channel facilitates the efficient transport of the liquid. The problem of soil freezing was solved as a task of a semi-infinite solid body, when the heat flux passing through the surface of the soil was about 5 W∙m−2, and the driving pressure was −9 °C. The operating pressure is established, the temperature profile is measured, and the coolant consumption and the type of porous structure are optimised. The economic impacts on one tree will make approximately $50, and for a fruit zone of the Republic of Kazakhstan, the economic impacts exceed 500 million dollars per year.

Further perfecting of these technologies is related to increasing of resolving power in analogue-to-digital and digital-to-analogue converters, requiring the improvement of quality indicator of the reference voltage sources such as noise level. This paper presents the possibilities for level reduction of output noise of the reference voltage sources. Circuit solutions of the single-stage and twostage, unipolar and bipolar low-noise sources of stable voltage of direct current produced on the basis of standard integral chips of voltage stabilizers are observed. The proposed circuit solutions provide reduction of output noise level of the reference voltage sources to the level of intrinsic noise of the operational amplifiers, which are part of the developed devices. It should be emphasized that single-stage unipolar low-noise sources of stable voltage of direct current are characteristic by the inversion of output voltage polarity that takes place in accordance with the polarity of output voltage of voltage stabilizer integral chip.

Extensive and continuous areas of urban greenery are essential for the proper functioning of cities and for achieving optimal natural conditions. The aim of our study was to investigate the changes in the areas of public green space of Szczecin, Poznań and Wrocław in the years 1996–2013, and compare data on public greenery with demographic data and changes in the spatial development of the described cities. We used a linear regression and exponential regression to explain the results. In our opinion, it is necessary to establish the appropriate proportion of public greenery to the built-up areas in cities. Otherwise, we will be observing an adverse reduction of green areas in relation to residential areas. Surveys also indicate the need for action to prevent the outflow of population to the suburban areas.
Population projections for Sweden, Norway, Denmark, and Finland, 2015–2065
Authors: Tarvainen Kyösti
Published: March 2018

The ethnic and religious compositions of Nordic populations have been projected by Eurostat (Lanzieri, 2011), the Pew Research Center (2015), and Statistics Denmark (2015). These studies are updated and complemented in this paper. Lanzieri’s consideration of the native population is supplemented by taking into account assimilation via marriages between natives and foreign-background persons. Immigration to Nordic countries increased significantly in 2015, but, on the other hand, immigration restrictions have been put in place. Therefore, there are no reliable estimates of future immigration. In this situation, the paper’s “what if” projections, incorporating the average 2012–2014 net immigration level, serve as useful reference information. The projected demographic changes are similar in the four Nordic countries. The development is fastest in Sweden; in 2065, the share of the native population is to decrease to 49%, the Western population is projected to fall to 63%, and the Muslim population increase to 25%.

The present study evaluated the effects of five species of arbuscular mycorrhizal fungi (AMF) on vegetative development parameters and nutrient uptake of persimmon (Diospyros kaki L.) seedlings. The experiment was carried out in a completely randomized experimental design with six treatments involving AMF inoculation (non-inoculated; Dentiscutata heterogama, Claroideoglomus etunicatum, Rhizophagus clarus, Acaulospora scrobiculata and A. morrowiae), in sterile soil (Oxisol – Dystrophic Red Latosol) under greenhouse conditions. Persimmon seeds were germinated in sterile sand and the seedlings were transplanted to the sterile soil and received AMF inocula. After 360 days, the following vegetative parameters were analyzed: plant height, number of leaves, leaf surface area, stem diameter, shoot and root dry mass, percentage of root colonization and nutrient accumulation in shoot and root biomass. We observed different responses to the AMF species tested. Seedling height and leaf surface area were promoted by inoculation with D. heterogama and A. morrowiae, and these species also promoted a higher percentage of root colonization. Plants inoculated with D. heterogama and C. etunicatum presented a greater number of leaves, but only D. heterogama promoted significant increases in stem diameter. Shoot dry mass was improved by inoculation with D. heterogama, A. morrowiae and C. etunicatum, while the first two species and R. clarus increased root dry mass. Nutrient accumulation in shoot and root biomass was stimulated by AMF inoculation, especially by D. heterogama and A. morrowiae. Therefore, the effects on early vegetative development were more pronounced in the persimmon seedlings inoculated with D. heterogama.
The Other Half of the Truth: Incidents in the Life of a Slave Girl, A First-Hand Account of Slavery from a Woman’s Perspective
Authors: Blidariu Şerban Dan
Published: March 2018

While Frederick Douglass’ autobiography is a classic and offers an image of slavery based on the memories of a former slave, that image remains incomplete because it is centered on attributes and events seen as predominantly masculine. For a more thorough understanding of what slavery was for all, another perspective must be put forth: that of a woman and a mother. In order to achieve this, the paper will focus on Incidents in the Life of a Slave Girl by Harriet Jacobs.
Folklore Studies on Birth Related Customs within the Banat Community
Authors: Alexin Otilia Daniela
Published: March 2018

Birth is perceived as a threshold, a milestone, and is best described as passing from one stage to another and from one status to another. This article aims to present the customs regarding the birth of a child, as they were preserved in the Banat folk mentality: the origin of the midwife and her role as mediator, the belief in the unfailing destiny foreseen by the book of fate, the rite of the first bath having a huge importance for the future of the child and a series of magic and religious acts meant to ward off the Evil forces that intend to harm the child and to restore the balance.
The F-measure for Research Priority
Authors: Rousseau Ronald
Published: March 2018

Purpose

In this contribution we continue our investigations related to the activity index (AI) and its formal analogs. We try to replace the AI by an indicator which is better suited for policy applications.

Design/methodology/approach

We point out that fluctuations in the value of the AI for a given country and domain are never the result of that country’s policy with respect to that domain alone because there are exogenous factors at play. For this reason we introduce the F-measure. This F-measure is nothing but the harmonic mean of the country’s share in the world’s publication output in the given domain and the given domain’s share in the country’s publication output.

Findings

The F-measure does not suffer from the problems the AI does.

Research limitations

The indicator is not yet fully tested in real cases.

R&D policy management

In policy considerations, the AI should better be replaced by the F-measure as this measure can better show the results of science policy measures (which the AI cannot as it depends on exogenous factors).

Originality/value

We provide an original solution for a problem that is not fully realized by policy makers.
Measuring and Visualizing Research Collaboration and Productivity
Authors: Garner Jon , Porter Alan L. , Leidolf Andreas , Baker Michelle
Published: March 2018

Purpose

This paper presents findings of a quasi-experimental assessment to gauge the research productivity and degree of interdisciplinarity of research center outputs. Of special interest, we share an enriched visualization of research co-authoring patterns.

Design/methodology/approach

We compile publications by 45 researchers in each of 1) the iUTAH project, which we consider here to be analogous to a “research center,” 2) CG1— a comparison group of participants in two other Utah environmental research centers, and 3) CG2—a comparison group of Utah university environmental researchers not associated with a research center. We draw bibliometric data from Web of Science and from Google Scholar. We gather publications for a period before iUTAH had been established (2010–2012) and a period after (2014–2016). We compare these research outputs in terms of publications and citations thereto. We also measure interdisciplinarity using Integration scoring and generate science overlay maps to locate the research publications across disciplines.

Findings

We find that participation in the iUTAH project appears to increase research outputs (publications in the After period) and increase research citation rates relative to the comparison group researchers (although CG1 research remains most cited, as it was in the Before period). Most notably, participation in iUTAH markedly increases co-authoring among researchers—in general; and for junior, as well as senior, faculty; for men and women: across organizations; and across disciplines.

Research limitations

The quasi-experimental design necessarily generates suggestive, not definitively causal, findings because of the imperfect controls.

Practical implications

This study demonstrates a viable approach for research assessment of a center or program for which random assignment of control groups is not possible. It illustrates use of bibliometric indicators to inform R&D program management.

Originality/value

New visualizations of researcher collaboration provide compelling comparisons of the extent and nature of social networking among target cohorts.
Trends Analysis of Graphene Research and Development

Published: March 2018

Purpose

This study aims to reveal the landscape and trends of graphene research in the world by using data from Chemical Abstracts Service (CAS).

Design/methodology/approach

Index data from CAS have been retrieved on 78,756 papers and 23,057 patents on graphene from 1985 to March 2016, and scientometric methods were used to analyze the growth and distribution of R&D output, topic distribution and evolution, and distribution and evolution of substance properties and roles.

Findings

In recent years R&D in graphene keeps in rapid growth, while China, South Korea and United States are the largest producers in research but China is relatively weak in patent applications in other countries. Research topics in graphene are continuously expanding from mechanical, material, and electrical properties to a diverse range of application areas such as batteries, capacitors, semiconductors, and sensors devices. The roles of emerging substances are increasing in Preparation and Biological Study. More techniques have been included to improve the preparation processes and applications of graphene in various fields.

Research limitations

Only data from CAS is used and some R&D activities solely reported through other channels may be missed. Also more detailed analysis need to be done to reveal the impact of research on development or vice verse, development dynamics among the players, and impact of emerging terms or substance roles on research and technology development.

Practical implications

This will provide a valuable reference for scientists and developers, R&D managers, R&D policy makers, industrial and business investers to understand the landscape and trends of graphene research. Its methodologies can be applied to other fields or with data from other similar sources.

Originality/value

The integrative use of indexing data on papers and patents of CAS and the systematic exploration of the distribution trends in output, topics, substance roles are distinctive and insightful.
