The h-index: a broad review of a new bibliometric indicator

Purpose – This review aims to show, broadly, how the h‐index has become a subject of widespread debate, how it has spawned many variants and diverse applications since first introduced in 2005 and some of the issues in its use.Design/methodology/approach – The review drew on a range of material published in 1990 or so sources published since 2005. From these sources, a number of themes were identified and discussed ranging from the h‐index's advantages to which citation database might be selected for its calculation.Findings – The analysis shows how the h‐index has quickly established itself as a major subject of interest in the field of bibliometrics. Study of the index ranges from its mathematical underpinning to a range of variants perceived to address the indexes' shortcomings. The review illustrates how widely the index has been applied but also how care must be taken in its application.Originality/value – The use of bibliometric indicators to measure research performance continues, with the h‐index .
ORGANIZATIONAL CYNICISM: ITS RELATIONSHIP WITH JOB SATISFACTION

Sometimes we all have the desire, impulse, or motivation to change what we consider not to be working for us, what we consider to be wrong or contrary to ethics or our personal values. But in many cases we realize instantly that what we want is not possible, that we are not the ones to fix all the things that are not working, or that we simply are not allowed to intervene where we would be able to. Often in organizations we can easily find such employees, completely committed, eager to "give it all" or even to give more than it is required from them. At the same time, on the opposite side, we find just the opposite employee. This type of employee, driven by pessimistic ideas, selfishness, and lack of interest, is the element which spoils the balance of the organizational frame in which he/she activates, and at the same time, his/her personal balance, as he/she is driven by a skeptical, negative, detached, and lacking in interest behaviour towards the organization he/she is part of
Prevalence of dilated cardiomyopathy in HIV-infected African patients not receiving HAART: a multicenter, observational, prospective, cohort study in Rwanda.

INTRODUCTION Several studies performed before the introduction of highly active antiretroviral therapy (HAART) have shown that HIV-1 infection is an important cause of dilated cardiomyopathy. However, factors associated with the development of HIV-associated cardiomyopathy in developing countries are still debated. OBJECTIVES To assess the prevalence of dilated cardiomyopathy, diagnosed by echocardiography, in HIV-infected Rwandese patients not receiving HAART and the risk factors associated with its development. METHODS A sample of 416 HIV-infected african patients, without a previous definite history of cardiovascular disease, attending University hospitals in Rwanda, from January to December 2005, were included in a multicenter, observational, prospective, cohort study, with the collaboration of two European Clinical Centers (in France and in Italy). Clinical and laboratory tests along with echocardiographic examination were performed in all patients included in the study. RESULTS Out of 416 patients included in the study, dilated cardiomyopathy was documented by echocardiography in 71 (17.7%). By both univariate and multivariate analysis, low socio-economic status, estimated duration of HIV-1 infection, CD4 count, HIV-1 viral load, CDC stage B and C of HIV disease and low plasmatic level of selenium were factors significantly associated with the development of cardiomyopathy. Alcohol consumption and smoking were factors associated with the development of cardiomyopathy only by univariate analysis. CONCLUSIONS HIV-associated cardiomyopathy is a significant clinical problem in HIV-infected patients not receiving HAART in Rwanda. Early tracking of cardiomyopathy in African HIV-infected patients is therefore recommended. Before administering HAART, clinicians should be aware of a possible existing cardiomyopathy to ensure appropriate, comprehensive, and rational patient care.
IgA pemphigus with paraneoplastic pemphigus‐like clinical features showing IgA antibodies to desmoglein 1/3 and desmocollin 3, and IgG and IgA antibodies to the basement membrane zone

A 79‐year‐old Japanese woman presented with severe recalcitrant erosions on her oral mucosa, resembling paraneoplastic pemphigus. Using indirect immunofluorescence, we detected IgA antibodies against the cell surface, and both IgG and IgA antibodies against the basement membrane zone. Immunoblotting showed that the IgG antibodies reacted weakly with bullous pemphigoid 230 and periplakin, whereas the IgA antibodies did not react with any antigen. IgA antibodies to both desmoglein (Dsg)1 and Dsg3 were detected by ELISA. IgA antibodies to desmocollin (Dsc)3 were also detected by using cDNAs for human Dsc1–3 transfected into COS‐7 cells. Despite treatment with oral prednisolone, high‐dose intravenous immunoglobulin and double‐filtration plasmapheresis, the skin lesions remained active, and the patient died from bronchiolitis obliterans‐like respiratory failure. Despite extensive investigations and postmortem examination, no underlying neoplasms were found. The complex immunopathological findings probably played an important role in the development of the patient's unusual clinical features.
Is There an App for That?

Everyday technologies (e.g., iPods, iPads, and Smart Phones) offer applications (apps) that can serve as supports to students with intellectual and related developmental disabilities. The extent to which apps that are currently on the market are aligned with the support needs of children was evaluated using the subscale framework of the Children's Supports Intensity Scale (Child-SIS). Recommendations for future research and app development are provided, and implications for how apps influence assistive technology (AT) consideration and the concept of technological abandonment are discussed.
Dechlorination of Atrazine by a Rhizobium sp. Isolate

A Rhizobium sp. strain, named PATR, was isolated from an agricultural soil and found to actively degrade the herbicide atrazine. Incubation of PATR in a basal liquid medium containing 30 mg of atrazine liter(sup-1) resulted in the rapid consumption of the herbicide and the accumulation of hydroxyatrazine as the only metabolite detected after 8 days of culture. Experiments performed with ring-labeled [(sup14)C]atrazine indicated no mineralization. The enzyme responsible for the hydroxylation of atrazine was partially purified and found to consist of four 50-kDa subunits. Its synthesis in PATR was constitutive. This new atrazine hydrolase demonstrated 92% sequence identity through a 24-amino-acid fragment with atrazine chlorohydrolase AtzA produced by Pseudomonas sp. strain ADP.
Comparison of dexmedetomidine and propofol used for drug-induced sleep endoscopy in patients with obstructive sleep apnea syndrome.

UNLABELLED Backround: Surgical operations are alternative treatments in persons with Obstructive Sleep Apnea Syndrome who cannot tolerate continuous positive airway pressure therapy. Drug-Induced Sleep Endoscopy is a method with which somnolence is pharmacologically induced and collapse is evaluated through nasal endoscopy in patients with Obstructive Sleep Apnea Syndrome. AIMS We aimed to evaluate efficiency of dexmedetomidine or propofol used for sedation in patients undergoing drug-induced sleep endoscopy. METHODS A total of 40 patients aged between 18 and 65 years old in the ASA STATUS I-II group were included in the study. After premedicatıon wıth midazolam 0.05 mg/kg intravenously, patients were randomly divided into two groups and administered intravenous (iv) propofol with the loading dose of 0.7 mg/kg for 10 minutes, followed 0.5 mg/kg/h infusion (Group P); or dexmedetomidine with the loading dose of 1 mcg/kg for 10 minutes, followed by 0.3 mcg/kg/h infusion (Group D). Haemodynamic and respiratuary parameters, Bispectral index score, Ramsey sedation score, time to achieve sufficient sedation, surgeon's and patients' satisfaction, postoperative Aldrete score and side effects were recorded. RESULTS Time to achieve sufficient sedation, Bispectral index scores at 5, 10 and 15th. minutes intraoperatively, first Aldrete score in the recovery room, SpO2 values and respiratory rates all over the surgical procedure and in the recovery room were found lower in Group P (P<0.05). Bispectral index scores, mean arterial pressure and heart rate in the recovery room were significantly lower in Group D (P<0.05). CONCLUSION Dexmedetomidine may be preferred as a safer agent with respecting to respiratory function compared with propofol in obstructive sleep apnea patients who known to be susceptible to hypoxia and hypercarbia.
A Beta‐Mixture Model for Assessing Genetic Population Structure

Summary An important fraction of recently generated molecular data is dominant markers. They contain substantial information about genetic variation but dominance makes it impossible to apply standard techniques to calculate measures of genetic differentiation, such as F‐statistics. In this article, we propose a new Bayesian beta‐mixture model that more accurately describes the genetic structure from dominant markers and estimates multiple FSTs from the sample. The model also has important application for codominant markers and single‐nucleotide polymorphism (SNP) data. The number of FST is assumed unknown beforehand and follows a random distribution. The reversible jump algorithm is used to estimate the unknown number of multiple FSTs. We evaluate the performance of three split proposals and the overall performance of the proposed model based on simulated dominant marker data. The model could reliably identify and estimate a spectrum of degrees of genetic differentiation present in multiple loci. The estimates of FSTs also incorporate uncertainty about the magnitude of within‐population inbreeding coefficient. We illustrate the method with two examples, one using dominant marker data from a rare orchid and the other using codominant marker data from human populations.
Storm time response of the midlatitude thermosphere: Observations from a network of Fabry‐Perot interferometers

Observations of thermospheric neutral winds and temperatures obtained during a geomagnetic storm on 2 October 2013 from a network of six Fabry‐Perot interferometers (FPIs) deployed in the Midwest United States are presented. Coincident with the commencement of the storm, the apparent horizontal wind is observed to surge westward and southward (toward the equator). Simultaneous to this surge in the apparent horizontal winds, an apparent downward wind of approximately 100 m/s lasting for 6 h is observed. The apparent neutral temperature is observed to increase by approximately 400 K over all of the sites. Observations from an all‐sky imaging system operated at the Millstone Hill observatory indicate the presence of a stable auroral red (SAR) arc and diffuse red aurora during this time. We suggest that the large sustained apparent downward winds arise from contamination of the spectral profile of the nominal thermospheric 630.0 nm emission by 630.0 nm emission from a different (nonthermospheric) source. Modeling demonstrates that the effect of an additional population of 630.0 nm photons, with a distinct velocity and temperature distribution, introduces an apparent Doppler shift when the combined emissions from the two sources are analyzed as a single population. Thus, the apparent Doppler shifts should not be interpreted as the bulk motion of the thermosphere, calling into question results from previous FPI studies of midlatitude storm time thermospheric winds. One possible source of contamination could be fast O related to the infusion of low‐energy O+ ions from the magnetosphere. The presence of low‐energy O+ is supported by observations made by the Helium, Oxygen, Proton, and Electron spectrometer instruments on the twin Van Allen Probes spacecraft, which show an influx of low‐energy ions during this period. These results emphasize the importance of distributed networks of instruments in understanding the complex dynamics that occur in the upper atmosphere during disturbed conditions.
Agent-based modelling and systems dynamics model reproduction

Reproducibility is a pillar of the scientific endeavour. We view computer simulations as laboratories for electronic experimentation and therefore as tools for science. Recent studies have addressed model reproduction and found it to be surprisingly difficult to replicate published findings. There have been enough failed simulation replications to raise the question, "can computer models be fully replicated? " This paper answers in the affirmative by reporting on a successful reproduction study using Mathematica, Repast and Swarm for the Beer Game supply chain model. The reproduction process was valuable because it demonstrated the original result's robustness across modelling methodologies and implementation environments.
Quantifying Chaotic Unpredictability of Vertical-Cavity Surface-Emitting Lasers With Polarized Optical Feedback via Permutation Entropy

To quantify the unpredictability of chaotic signals generated by vertical-cavity surface-emitting lasers (VCSELs) subject to polarized optical feedback, we numerically investigate the properties of recently introduced quantifier based on information theory, i.e., permutation entropy (PE) H. VCSEL1 subject to polarization-preserved optical feedback and VCSEL2 subject to polarization-rotated optical feedback are considered. The H for X-polarization (XP) mode, Y-polarization (YP) mode, and total output for both VCSELs are discussed and compared in detail. The influences of feedback strengths, feedback delays, and injection currents are focused on. For lower injection current, the 2-D maps illustrate that the trends of H for the XP mode, YP mode, and total output are different for both VCSELs. While for higher injection current, the values of H for both VCSELs increase with the feedback strengths, are not sensitive to feedback delays, and are higher than the counterparts for lower injection current. Moreover, the H increases with injection current for both VCSELs with a decreasing slope. These results show that the PE is an effective tool for quantifying the degree of unpredictability of chaotic signals of VCSELs, and provides valuable information for choosing the proper chaotic carrier.
Methylmercury in mosquitoes around a large coal‐fired power plant in central Ohio

Emissions from coal‐fired power plants are the major anthropogenic source of mercury (Hg) in the environment. Because emitted Hg can be deposited near the source, concerns arise about the effects of coal‐burning facilities on levels of toxic methylmercury (MeHg) in biota near such sources. We investigated the potential impact of a large Hg‐emitting (450 kg in 2005) coal‐fired power station in Conesville, Ohio, on MeHg levels in adult mosquitoes near the plant. In July 2010, mosquitoes were sampled at 23 locations within a 60‐km radius of the plant and at three reference sites distant from major combustion sources of Hg. Nearly all of the Hg in mosquitoes appeared in the form of MeHg (mean = 91%). Concentrations of MeHg in mosquitoes were unrelated to either distance or direction from the Conesville plant and did not differ from those at the three reference sites. Moreover, measured levels of MeHg in mosquitoes near Conesville are in good agreement with those predicted from an empirical relationship to wet atmospheric Hg fluxes alone. This suggests that either little of the Hg emitted from the Conesville plant is deposited locally or near‐source deposition of Hg does not have a significant impact on MeHg in mosquitoes and, by extension, other insects with similar life histories in the local food web.

Segmental Maternal UPD6 with Prenatal Growth Restriction

We report a child with segmental maternal uniparental isodisomy of chromosome 6, involving most of the long arm distal to 6q16, detected by SNP microarray. Clinical features include prenatal growth restriction, global developmental delay, and severe gastro-esophageal reflux disease. Maternal uniparental disomy (UPD) of chromosome 6 has previously been reported to cause intrauterine growth restriction. Paternal UPD of this chromosome is well known to cause transient neonatal diabetes mellitus. We discuss reported cases of maternal UPD of chromosome 6 and consider whether our patient’s features may be due to disordered imprinting or unmasking of an autosomal recessive condition.
Extended Chained Forms and Their Application to Nonholonomic Kinematic Systems with Affine Constraints: Control of a Coin on a Rotating Table

This paper proposes a transformation method from a class of asymmetric affine control systems into extended chained forms and considers their application to control of non-holonomic kinematic systems with affine constraints (NKSAC). Firstly, we give problem setting and an assumption for a class of asymmetric affine control systems. Then, a transformation into extended chained forms is derived. We next consider control of a coin on a rotating which is a physical example of the NKSAC and introduce a control algorithm for the system by using the extended chained form. Finally, some simulation results of the system are shown to confirm the effectiveness of our research
Linking employees' justice perceptions to organizational commitment and intention to leave: The mediating role of perceived organizational support

Building on the social exchange perspective and organizational support theory, this study examined the relationships among employees' justice perceptions, perceived organizational support (POS), organizational commitment and intention to leave. A hypothesized model was developed and tested using hierarchical regression analyses on a sample of 514 practising solicitors in Hong Kong. The results showed that both procedural and distributive justice contributed to the development of POS, and POS mediated their effects on organizational commitment and intention to leave. As expected, organizational commitment was negatively related to intention to leave. Additional analyses revealed that these relationships held for both partners and non-partners in law firms.
The Nutrition of Brucellae: Growth in Simple Chemically Defined Media

The nutritional requirements of brucellae grown in chemically defined media have been investigated by ZoBell and Meyer (1932a,b), Koser, Breslove, and Dorfman (1941), N. B. McCullough and Dick (1942a,b, 1943), W. G. McCullough et al. (1947), and others. With one exception (McCullough and Dick, 1943), however, the media employed seemed unduly complex by reason of the number of amino acids required in their preparation. Utilization of inorganic ammonium salts as the sole nitrogen source for these organisms has been demonstrated by ZoBell and Meyer (1932a), McCullough and Dick (1943), and Gerhardt and Wilson (1947). Consequently, the present study was undertaken in an effort to obtain a simple, chemically defined medium for cultivation of brucellae. Interest in this laboratory has centered on the "avirulent" Brucela abortue strain 19, widely used for animal immunization. The nutritional requirements of this culture were studied intensively and the findings applied subsequently to a number of other strains.
Hepatosplenic T cell lymphoma in inflammatory bowel disease

The development of lymphoma in chronic inflammatory conditions has been a topic of great interest. Studies in inflammatory bowel disease (IBD) have demonstrated conflicting results and it is often difficult to disassociate disease severity, disease duration and the risk attributable to drug exposure. Recently presented results from the very large French population based CESAME study suggest a doubling of the risk of lymphoma in patients with IBD, with the majority of cases occurring in association with immunosuppressive therapy. Similarly, a meta-analysis of previous cohort studies concluded that the risk of lymphoma is increased four-fold in patients with IBD on thiopurine treatment (azathioprine and 6-mercaptopurine) compared to those not receiving such therapy. Such analyses cannot demonstrate causation, and it is possible that an increased lymphoma risk relates to more active underlying disease rather than thiopurine therapy, an interpretation supported by results from studies in IBD patients unexposed to such treatment.
EFFECT OF MANNAN OLIGOSACCHARIDES ON THE ILEAL MORPHOMETRY AND CECAL FERMENTATION OF GROWING RABBITS

A common problem in rabbits is the occurrence of digestive disorders just after weaning. This problem is usually associated with instability of the cecal microflora and characterized by diarrhea, loss of appetite and increased mortality. In the current study the effects of a mannan oligosaccharide (MOS, Bio-MOS ® , Alltech Inc. USA) was compared to a commonly used antibiotic (AGP, Zn-Bacitracin). The current study investigated the effects of MOS and AGP on intestinal morphometry and cecal VFA production. A total of 220 weaned mixed-sex rabbits (32d) were divided into 5 experimental treatments and housed in groups of 4 in 55 flat deck cages located in an experimental rabbit house. The 5 experimental treatments were as follow: Control (no additives);MOS 1 (1 kg MOS/t); MOS 1.5 (1.5 kg MOS/t); MOS 2 (2 kg MOS/t) and AGP (0.1 kg/t). Experimental diets were based on alfalfa, sunflower meal and wheat and beet pulp and were offered ad libitum through out the experiment. Intestinal morphology and cecal fermentation was determined in 8 rabbits per treatment slaughtered at day 46. Histologic examination showed significantly longer villi (P<0.05) in rabbits fed MOS (503.1, 518.6 and 508.8 for MOS 1, MOS 1.5 and MOS 2, respectively) or AGP (502.5) compared to the control group (403.0). This was also translated into a numerically increased absorption surface. Cecal volatile fatty acid (VFA) concentration differed significantly (P<0.05) between treatments. Rabbits fed MOS at 1 kg/t had the highest total VFA concentration (98.02 vs. 51.57 in MOS 1 and Control) and higher butyric acid (14.09 vs. 4.59 in MOS 1 and Control). Furthermore cecal pH was significantly lower in rabbits fed MOS at 1 kg/t and 2 kg/t (5.79 and 5.92) compared to the control (6.33). Results for this study suggest that MOS has a stimulating effect on villi development and production of cecal VFA and reduce cecal pH, which could improve the health status of growing rabbits.
