| 1 | 基于K-核塌缩序列的社会化资源推荐中核心用户发现研究显示文摘【目的】通过对社交网站平台用户行为的分析,发现社会化小众群体中的核心用户,为社会化资源推荐服务提供参考。【方法】收集豆瓣读书用户的1 208个标签,对排名前100位的标签建立标签共现矩阵,分析用户的K-核网络结构,研究用户的K-核塌缩序列的波动情况。【结果】与度数中心度、最小K-核深度值等方法相比,基于K-核塌缩序列方法发现了新的社会化小众群体中的核心用户。【局限】样本数据规模较小且局限于某领域,排序问题不能得到很好的解决,需要进一步改进K-核分析方法。【结论】本研究有利于社交网站平台的管理者制定或改进新的资源推荐策略,从而促进社交网站平台更好地发展。 | 武慧娟 Jia Tina Du 孙鸿飞 Jannatul Fardous | 2016 | 现代图书情报技术2016，，9： | 2 |

| 4 | Assessment of natural regeneration status and diversity of tree species in the biodiversity conservation areas of Northeastern Bangladesh显示文摘A study was conducted at two-biodiversity conservation areas of Northeastern Bangladesh (a part of Sylhet Forest Division) to assess the species composition, diversity and density of natural regeneration of tree species both indigenous and exotic species. Data were collected by stratified random quadrate method during January 2010 to July 2010. Totally 200 circular plots of 2 m×2 m in size had 5 different habitat types of plants namely; forest, roadside, homestead (surrounding forest dwellers house), fallow land and others (canals, streams and tea gardens side), which included a total of 55 regenerating species belonging to 28 families. Meliaceae is the dominant family and shows the highest family importance value (26.3), having six species, followed by Moraceae (24.24). Among the five habitat types, forest (43 species) possess the highest number of species, followed by roadside (23 species). Total 15 exotic species among 9 families and 40 indigenous species with 24 fami- lies were recorded. For exotic species, Tectona grandis possess the high- est relative density (11.7%) and relative frequency (10.5%); Senna sia- mea had highest relative abundance (7.83%). In case of indigenous spe- cies, Chickrassia tabularis possess the highest relative density (4.23%) and relative frequency (4%); Dipterocarpus turbinatus had the highest relative abundance (3.92%). Tectona grandis (29.66) and Chickrassia tabularis (10.8) had the highest IVI for exotic and indigenous species respectively. Different diversity indices such as Shanon-Winner diversity index, species diversity index, species richness index, species evenness index, Simpson index and species dominance index, etc. were applied to quantify definite diversity. The regeneration of species associated with low levels of disturbance was in the exotic species. Study suggests that proper protection from human disturbances and scientific management ofnatural regeneration of two-study forests may lead a rich biodiversity site in the country. | Md.

| 5 | A multidisciplinary method to assess the reproductive biology of Mystus bleekeri显示文摘The study aims to afford a deeper knowledge on reproductive biology of Mystus bleekeri from Surma River,Bangladesh in a multidisciplinary way.Though,the species is in demand as food and ornamental fish in Bangladesh but still now comprehensive details on reproductive biology of this species is scanty.Total 600 fish samples were derived from commercial catches from July 2018 to June 2019.Periodic differences in sex ratio,size distribution,condition factor(Kn),fecundity,gonadosomatic index and gonadal maturation cycle were assessed.The results showed 384(64%)female and 216(36%)male with an overall sex ratio of 1.77:1(female:male).Mean total length(TL)and body weight(BW)of all fish studied were 14.85±3.38 cm TL and 27.54±15.76 g,respectively.The Kn varied with length groups,the highest(1.45±0.23)and lowest(0.89±0.18)values obtained in 16.0-16.9 and 10.0-10.9 cm TL groups,respectively.The highest Kn was documented in October while the lowest was in January.Monthly GSI values showed two peaks in July and November for both the sexes.The fecundity was found to vary from 1120 to 14790 eggs with average value of 4968±3047 with 14.4-18.3 cm in TL and 19.97-34.7g in BW.The relationship of fecundity with TL and BW was F=1.385TL13.405,r^(2)=0.885 and F=5.201BW^(4.827),r^(2)=0.944.Partial behavior of spawning together with allochronic oocytes development has also been found through histology.The results of this study could be used for predicting the response of populations of fish in Surma River and/or other where to human interferences and environmental change. | Tamanna Sultana Sabuj Kanti Mazumder Jannatul Kubra Nurnobi Nishad Sarker Mohammad Ibrahim Khalil Simon Kumar Das Md.Arifur Rahman Khan Md.Tawheed Hasan | 2023 | Aquaculture and Fisheries2023，8，3： | 0 |
