Explaining the past, predicting the future: the influence of regional trajectories on innovation networks of new industries in emerging economies
No full textEconomic geographers have recently made important contributions to understanding of the relationship between regional transformation, industrial specialisation and innovation networks in the emergence of new industries. However, most contemporary research has focused on the influence of networks on regional trajectories, paying lip service to how regional trajectories also influence network configurations. Furthermore, international comparative research on how specific regional innovation system (RIS) trajectories may shape innovation networks in new industrial sectors is underdeveloped. The paper investigates how the trajectories of Bangalore and Beijing RISs influence the objectives and geographical configuration of innovation networks in the new media industry. The co-evolution of different elements of the RIS trajectory points to the unfolding of a politically and institutionally driven trajectory in Beijing, and a cognitively driven trajectory in Bangalore. These trajectories lead to specific barriers and opportunities for the development of innovation networks in new industries
Assessment of sleep in ventilator-supported critically III patients
No full textOBJECTIVES:
In critically ill patients, sleep derangements are reported to be severe using Rechtschaffen and Kales (R&K) methodology; however, whether such methodology can reliably assess sleep during critical illness is unknown. We set out to determine the reproducibility of 4 different sleep-assessment methods (3 manual and 1 computer-based) for ventilator-supported critically ill patients and also to quantify the extent to which the reproducibility of the manual methods for measuring sleep differed between critically ill and ambulatory (control) patients.
DESIGN:
Observational methodologic study.
SETTING:
Academic center.
PATIENTS:
Critically ill patients receiving mechanical ventilation and age-matched controls underwent polysomnography.
INTERVENTIONS:
None.
MEASUREMENTS AND RESULTS:
Reproducibility for the computer-based method (spectral analysis of electroencephalography [EEG]) was better than that for the manual methods: R&K methodology and sleep-wakefulness organization pattern (P = 0.03). In critically ill patients, the proportion of misclassifications for measurements using spectral analysis, sleep-wakefulness organization pattern, and R&K methodology were 0%, 36%, and 53%, respectively (P < 0.0001). The EEG pattern of burst suppression was not observed. Interobserver and intraobserver reliability of the manual sleep-assessment methods for critically ill patients (kappa = 0.52 +/- 0.23) was worse than that for control patients (kappa = 0.89 +/- 0.13; P = 0.03). In critically ill patients, the overall reliability of the R&K methodology was relatively low for assessing sleep (kappa = 0.19), but detection of rapid eye movement sleep revealed good agreement (kappa = 0.70).
CONCLUSIONS:
Reproducibility for spectral analysis of EEG was better than that for the manual methods: R&K methodology and sleep-wakefulness organization pattern. For assessment of sleep in critically ill patients, the use of spectral analysis, sleep-wakefulness organization state, or rapid eye movement sleep alone may be preferred over the R&K methodology

Coauthor prediction for junior researchers
No full textResearch collaboration can bring in different perspectives and generate more productive results. However, finding an appropriate collaborator can be difficult due to the lacking of sufficient information. Link prediction is a related technique for collaborator discovery; but its focus has been mostly on the core authors who have relatively more publications. We argue that junior researchers actually need more help in finding collaborators. Thus, in this paper, we focus on coauthor prediction for junior researchers. Most of the previous works on coauthor prediction considered global network feature and local network feature separately, or tried to combine local network feature and content feature. But we found a significant improvement by simply combing local network feature and global network feature. We further developed a regularization based approach to incorporate multiple features simultaneously. Experimental results demonstrated that this approach outperformed the simple linear combination of multiple features. We further showed that content features, which were proved to be useful in link prediction, can be easily integrated into our regularization approach. © 2013 Springer-Verlag
Testing for fullerenes in geologic materials: oklo carbonaceous substances, karelian shungites, sudbury black tuff: comment and reply
No full textThe presence of low concentrations of fullerenes has been reported from numerous terrestrial and meteoritic sources (Buseck, 2002). In a recent paper, Mossman et al. (2003) present mass spectra of carbonaceous substances using laser desorption ionization (LDI) and high-resolution electron-impact mass spectrometry. The authors confirm the presence of fullerenes in the Onaping Formation, Black Tuff from Sudbury, Ontario, but do not find fullerenes in carbon-rich shungite rocks from the Lake Onega region of Karelia, Russia. They conclude that the earlier observation of fullerenes in Karelian shungite may have been due to the intrusion of basic igneous rocks and attribute the absence of fullerenes in the four shungite samples they studied to the possible heterogeneity of shungites. However, the authors also argue: "Alternative explanations include the possibility that fullerenes do not occur in shungite, or that the discovery of fullerenes in shungite may have been an artifact of the analyses" (Mossman et al., 2003, p. 257). Moreover, the authors conclude that natural fullerenes appear to form exclusively in extraterrestrial samples. We disagree with these conclusions. The first discovery of natural fullerenes in a geological sample was reported in shungite from Karelia (Buseck et al., 1992). Ebbesen et al. (1995) speculated that the fullerenes found in shungite were products of a localized event or were due to an experimental artifact; these arguments were challenged by Buseck and Tsipursky (1995). We subsequently reported the presence of fullerenes in shungite samples from Kondopoga (60 km southwest of Shunga), a different locality in Karelia (Parthasarathy et al., 1998). The sample was a bright shungite with ~10 wt% carbon. We used electron-impact ionization mass spectrometer (EIMS) in our experiments for the characterization of fullerenes. In contrast to LDI, which is known to create fullerenes under laser irradiance, EIMS is very safe for detecting fullerenes. The presence of fullerenes in Karelian shungite was confirmed independently by powder X-ray diffraction (XRD) and 13C-nuclear magnetic resonance (NMR) experiments (Parthasarathy et al., 1998). Hence, we do not agree with Mossman et al. (2003) that the fullerenes reported from shungite were due to experimental artifacts. As has been pointed out by many people, Mossman et al. (2003) among them, Karelian shungite is highly heterogeneous. Fullerenes have only been found in the glassy variety of bright shungite (Buseck et al., 1992; Parthasarathy et al., 1998). We have carried out a series of experiments exploring the presence of fullerenes in shungite from different areas of Karelia. We present here a typical mass spectra obtained from a dull shungite, in which the total carbon content was estimated to be 60 wt%. Figure 1 shows the mass spectrum of the carbonaceous matter extracted from a dull shungite and exhibits the absence of fullerene. Out of twelve Karelian shungite samples we found fullerenes in only three samples, all of which are bright shungite of glassy nature (Parthasarathy et al., 1998)

Comparison Of Fibers Properties Of Azadirachta Indica And Acacia Arabica Plant For Lightweight Composite Application
No full textIn this paper, the bark of Azadirachta Indica and Acacia Arabica plant is analysed for investigating and comparing. The aim is to investigate the potential use of these fibres as reinforcements in polymeric materials. The physicochemical properties of Azadirachta Indica fibres (AIFs) and Acacia Arabica fibres (AAFs) are examined by chemical constitutions, X-ray diffraction, thermogravimetry analysis, Fourier transform infrared spectroscopy analysis, and surface morphological analysis. AIF has a cellulose content of 68.42 wt.%, density of 740 kgm–3, crystallinity index of 65.04%; AAF has a cellulose content up to 68.1 wt.%, density equal to 1028 kgm–3 and crystallinity index of 51.72% respectively. The maximum peak temperature obtained in differential thermogravimetry (DTG) curve is 321.2°C for AIF, and 345.1°C for AAF. The physicochemical results confirm the structural application of AIF and AAF for several industrial fields
