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

The Right to Strike under the United States Constitution: Theory, Practice, and Possible Implications for Canada
No full textAnswering critics of the Canadian Supreme Court's judgment in B.C. Health, the author argues that the Court laid the foundation for a principled and durable doctrine protecting constitutional labour rights, one that goes directly to the heart of the matter — the inequality of workers’ power in the employment relation. In the author’s view, two paths could lead from B.C. Health to the recognition of Charter protec- tion for a right to strike: one that treats the right as an accessory to col- lective bargaining, and one that upholds the right directly on the basis of the Charter values of equality and participation. The author supports the latter approach, contending that constitutional rights should be defined in relation to fundamental values, in a way that is not contingent on time-bound or fact-sensitive assessments about the role of strikes within a particular collective bargaining regime. Although a Charter right to strike may involve the courts in difficult choices about when to defer to legislative policy decisions, and courts may lack the institutional capac- ity to deal effectively with labour law issues, the author points out that judges can look to ILO standards for expert guidance. Noting that the U.S. experience in this area might be of considerable use to Canadians, the author concludes by providing an overview of American case law concerning a constitutional right to strike.Peer reviewe
Oil structuring: polymer bridging mechanism for structuring soft materials using natural emulsions as templates
No full textUsing a bridging flocculation mechanism in the design of oleogels materials constitutes an alternative framework to achieve desired rheological properties of oil-in-water emulsions. Aggregation by polymer bridging generates a droplet network linked together by firmly bound polymer bridges. In this dissertation, we used negatively charged polysaccharides, sodium alginate, xanthan gum, and ι-carrageenan as the structuring agents and soybean oleosomes as the template. Bridging flocculation between polysaccharides and oleosomes was induced by mixing and adjusting the pH to values where both are oppositely charged, leading to electrostatic-driven interactions. Our results indicate that polysaccharides with flexible polymer chains, such as sodium alginate and ι-carrageenan, are effective bridging flocculants.
In contrast, polysaccharides with a more rigid backbone, such as xanthan gum, resulted in depletion flocculation characterized by phase separation between oleosome droplets and xanthan molecules. Bridging flocculation is more effective at an optimum dosage between polysaccharides and oleosomes, expressed as a mass ratio (g polysaccharide/g oleosome) or as an equivalent per droplet surface area (mg/m2). Sodium alginate presented a higher bridging ability than ι-carrageenan, with its optimum bridging ratio at 0.005 g/g and ι-carrageenan at 0.01 g/g. This was confirmed by quantitative analysis of oleosome content upon centrifugation recovery, where sodium alginate yielded more compact and concentrated gels than ι-carrageenan. Differences in structural conformations between sodium alginate and ι-carrageenan account for the difference in bridging ability. Sodium alginate presents a co-block arrangement of alternating charged and uncharged parts. The negatively charged blocks adsorb strongly onto the oleosome interface at several charged units. At the same time, the uncharged parts impart a high degree of flexibility, allowing the polymer chains to bridge several droplets together.
On the other hand, ι-carrageenan is less flexible than alginate, making the individual carrageenan chains more effective for oleosome surface coating but less effective for bridging neighboring droplets. This difference in bridging ability between sodium alginate and ι-carrageenan will influence the structure of the aggregated network and, as a result, will be responsible for the mechanical behavior in rheological measurements. Sodium alginate produced more heterogeneous and interconnected structures, while ι-carrageenan produced smaller and less interconnected clusters. This difference in microstructure and the effect of the structural conformations in the polysaccharide chains becomes relevant at medium and large deformations in amplitude sweeps oscillatory rheology. At deformations between 3- 100%, sodium alginate presented steeper slopes in the moduli G’, indicating sudden microstructure fracture.
In contrast, ι-carrageenan presented less steep slopes indicating yielding rather than fracture behavior in the decrease of the moduli G’. At deformations between 200- 300%, the moduli presented an overshoot indicating a “cage effect” where individual droplets are immobilized due to crowding by surrounding droplets. This effect was more clearly prominent in conditions leading to the densest structures, such as in the compacted gels upon centrifugation performed at the optimum bridging ratios for sodium alginate (0.005 g/g) and ι-carrageenan (0.01 g/g). This study offers many perspectives on how to construct the macroscopic functional properties of oleogels in accordance with their application using the molecular architecture of polysaccharides
G-Rank: Unsupervised Continuous Learn-to-Rank for Edge Devices in a P2P Network
No full textRanking algorithms in traditional search engines are powered by enormous training data sets that are meticulously engineered and curated by a centralized entity. Decentralized peer-to-peer (p2p) networks such as torrenting applications and Web3 protocols deliberately eschew centralized databases and computational architectures when designing services and features. As such, robust search-and-rank algorithms designed for such domains must be engineered specifically for decentralized networks, and must be lightweight enough to operate on consumer-grade personal devices such as a smartphone or laptop computer. We introduce G-Rank, an unsupervised ranking algorithm designed exclusively for decentralized networks. We demonstrate that accurate, relevant ranking results can be achieved in fully decentralized networks without any centralized data aggregation, feature engineering, or model training. Furthermore, we show that such results are obtainable with minimal data preprocessing and computational overhead, and can still return highly relevant results even when a user’s device is disconnected from the network. G-Rank is highly modular in design, is not limited to categorical data, and can be implemented in a variety of domains with minimal modification. The results herein show that unsupervised ranking models designed for decentralized p2p networks are not only viable, but worthy of further research.https://github.com/awrgold/G-RankComputer Scienc

Non-genomic effects of progesterone on the signaling function of G protein-coupled receptors
No full textAbstractProgesterone at concentrations between 10 μM and 200 μM affected the calcium signaling evoked by ligand stimulation of G protein-coupled receptors expressed in several cell lines. At 160 μM progesterone the signaling of all receptors was completely abolished. The effect of progesterone was fast, reversible and was not prevented by cycloheximide indicating its non-genomic nature. Overall, the action of progesterone was more cell type-specific than receptor-specific. Our results are in contrast to a recent report [Grazzini, E., Guillon, G., Mouillac, B. and Zingg, H.H. (1998) Nature 392, 509–512] in which a direct high-affinity interaction between the oxytocin receptor and progesterone was suggested
