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

Adaptive pastoralists—Insights into local and regional patterns in livelihood adaptation choices among pastoralists in Kenya
No full textPastoralist adaptation strategies have to address multiple, overlapping, and often inter-related processes of socio-ecological change. The present study addresses the need for inter-regional comparative studies that account for different geographic, climate, and socio-economic contexts in order to understand how pastoralists adapt to changes in livelihood conditions. The paper uses data from a unique survey study of pastoralist households in four neighbouring counties in dryland Kenya. Taking our point of departure from an empirically based classification of the livelihood strategies available to pastoralists in the Horn of Africa, the survey offers novel insights into adaptation and fodder management strategies of pastoralist individuals and households. The results show that the use of migration as a strategy is more dependent on the ability to migrate than climate conditions. This is the case in localities where a substantial part of the land is subdivided, the population density is high, and where opportunities for migration are subsequently restricted. Diversification of livelihoods as a strategy is largely defined by opportunity. Intensification through active fodder management is mainly common in areas where there has been a proliferation of managed enclosures. Climate change will test the adaptive capacity of pastoralists in the studied region, and diversification and intensification strategies of both herd composition and livelihoods can be seen as strategies for increased climate resilience.Validerad;2023;Nivå 2;2023-11-14 (sofila);Full text license: CC BY;For corrigendum, see: Bostedt G, Knutsson P, Muricho D, Mureithi S, Wredle E and Nyberg G (2024) Corrigendum: Adaptive pastoralists—insights into local and regional patterns in livelihood adaptation choices among pastoralists in Kenya.

Adoption of Improved Groundnut Varieties in Uganda
No full textThis paper evaluates the level of adoption of improved groundnut varieties and the role of
information, seed supply and credit constraints for variety adoption in rural Uganda. We use
large-scale primary survey data collected in seven groundnut growing districts to understand
the adoption behavior of farm households and the key determinants of variety uptake. The study
finds that the level of adoption of improved varieties in Uganda is very high; about 59% of the
households grow improved varieties. About 62% of the groundnut area is planted to improved
varieties, indicating a high intensity of adoption. On average, the income per ha from improved
varieties is about 80% higher than local cultivars. Owing to the interdependence of variety
choice decisions, we use a multivariate probit specification to identify variety-specific drivers of
adoption. About 10% of farmers lack information on new varieties, while 18% and 6% cannot
adopt mainly due to seed supply and capital constraints, respectively. This indicates that a tobittype
specification, which considers all non-adopters as disinterested in the technology would
lead to inconsistent parameter estimates and misguided conclusions. We therefore estimate a
modified multi-hurdle specification, which takes into account the information, seed supply and
capital constraints in determining the desired demand and intensity of adoption of new groundnut
varieties. These findings provide new insights as to why adoption of new agricultural technologies
in Africa has lagged behind – not so much due to lack of economic incentives, but due to the
persistent failure to provide vital information along with seeds and required credit to translate the
desired positive demand into effective and actual adoption of new varieties. These are important
lessons that need to be considered as Africa searches for alternative pathways to launch an
effective and sustainable green revolution that will transform smallholder agriculture.

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
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
