No full textAbstract This research shows the general view on acquisition of forest resources by local communities. Forest not only provides provisioning services rather it is a concrete source of economic, social, political and cultural process as well. The study is conducted in Tapkeshwari Forest which is located far district of Kuch, Gujarat named as "Bhuj". The perception of community and impact of people on forest is main focal point of this research. Two villages named Haripur and Jadura which are adjoining villages near forest were sampled. The research was conducted merely on the basis of focal group discussion and prepared questionnaire which was asked to villagers. 82.5% of villagers responded that they collect firewood only from forest; 80% of households collect fodder from the forest and approximately 95% of households use the forest to graze their animals. Firewood is used as major fuel energy source for cooking at the households. A total of 82.5% of households were using firewood for cooking in the study area whereas 72.5% use Timber product. Haripur and Jadura village has together of 468 numbers of livestock which depend daily in Tapkeshwari Forest. Goats and Sheep are in large numbers that graze in forest for a longer period of time followed by cow. Detailed vegetation analysis and regeneration status of the forests are necessary as they form the basis for future plans to manage and restore these vanishing resources

Functional leaf traits indicate phylogenetic signals in forests across an elevational gradient in the central Himalaya
No full textKrishna M, Winternitz J, Garkoti SC, Penuelas J. Functional leaf traits indicate phylogenetic signals in forests across an elevational gradient in the central Himalaya. Journal of plant research. 2021.Traits are the primary attributes that distinguish a species niche. Species and higher taxa are part of a structured phylogeny, and variation in plant traits depends on lineage as well as on environmental conditions. Therefore, it is crucial to investigate linkages between taxonomic identity, shared ancestry, and environment for understanding the variation in leaf traits. We investigated the evolutionary relationships, based on multiple gene sequences among 26 plant species sampled along an elevational gradient from 650 to 3600m a.s.l. in the central Himalaya. We tested for the phylogenetic signal based on three different measures in 10 leaf traits having a significant association with the resource acquisition-conservation trade-offs axis and influencing plant growth, development, and ecological performance. We further assessed the role of elevation and growth forms as the potential drivers of leaf traits variation while controlling for phylogeny. 5 out of 10 leaf traits showed significant phylogenetic signal. Plant species clustered more often by growth forms at the tips of the phylogeny indicating multiple instances of independent evolution. Evergreen taxa showed niche separation with deciduous and incorporated larger trait variation. Trait variations were guided by both growth forms and elevation when accounted for phylogeny. Growth form has a higher contribution to trait variation compared to elevation. Trade-offs were detected between resource conservation and resource acquisition machinery traits (that would maximise carbon gain), differing between growth forms and along elevation
Dynamic Prediction of Delays in Software Projects using Delay Patterns and Bayesian Modeling
No full textModern agile software projects are subject to constant change, making it essential to re-asses overall delay risk throughout the project life cycle. Existing effort estimation models are static and not able to incorporate changes occurring during project execution. In this paper, we propose a dynamic model for continuously predicting overall delay using delay patterns and Bayesian modeling. The model incorporates the context of the project phase and learns from changes in team performance over time. We apply the approach to real-world data from 4,040 epics and 270 teams at ING. An empirical evaluation of our approach and comparison to the state-of-the-art demonstrate significant improvements in predictive accuracy. The dynamic model consistently outperforms static approaches and the state-of-the-art, even during early project phases.Software EngineeringSoftware Technolog
Ethnopedological knowledge of upland Karbi Community: A case study from Dima Hasao District of Assam, North-Eastern Himalaya, India
No full text30-39This paper describes the ethnopedological knowledge of indigenous upland Karbi farmers inhabiting a hilly area of Assam, India. Semi-directive interviews, focused group discussion and joint field visit methods were used for eliciting information on soil from key knowledge holders identified through chain referrals. Soil was classified into eight folk types based on fertility which were determined via its physical properties viz., colour, texture, water retention capacity and compactness. This classification helped them in land-use and crop-selection related decisions and some other uses. Plant species viz., Albizia spp., Imperata cylindrica, Lantana camara and Schima wallichii indicating soil fertility were valued for identification of most suitable jhum sites. To minimize soil erosion, indigenous techniques like inverted ‗U‘ shaped channels, maintaining standing trees and cut stumps, and placing horizontal wooden logs across shifting agricultural fields on steep slopes were employed. The laboratory analysis of physico-chemical parameters viz., bulk density, colour, texture, water holding capacity, pH, soil organic carbon and total nitrogen support the ethnopedological knowledge of the farmers. Study may help in preservation and protection of local knowledge on soil which is eroding fast under the influence of modernity
Pursuing an Elusive Seeker of Universal Truth – the Identity and Environment of the Author of the Dabistān–i Mazāhib
No full textProfessor Athar Ali (born 18 January 1925) studied at Aligarh Muslim University 1948–53. His PhD studies were supervised by Professor Satish Chandra. In 1953 he was appointed research assistant at the university and became a Professor in 1978. He was Wilson Fellow at the Smithsonian Institute in 1986, Smuts Fellow, Cambridge, 1974–5 a nd President of the Indian History Congress in 1989. His major publications are The Mughal Nobility under Aurangzeb (Aligarh, 1966) and The Apparatus of Empire (Delhi, 1985). Sadly he died not long after this article was accepted for publication and was therefore unable to see it in print.</jats:p
