Author Co-Citation Analysis (ACA): a powerful tool for representing implicit knowledge of scholar knowledge workers
No full textIn the last decade, knowledge has emerged as one of the most important and valuable organizational assets. Gradually this importance caused to emergence of new discipline entitled ―knowledge management‖. However one of the major challenges of knowledge management is conversion implicit or tacit knowledge to explicit knowledge. Thus Making knowledge visible so that it can be better accessed, discussed, valued or generally managed is a long-standing objective in knowledge management. Accordingly in this paper author co- citation analysis (ACA) will be proposed as an efficient technique of knowledge visualization in academia (Scholar knowledge workers)
Dengelenmış ve dengesiz gerilim kuvvetlerinin köpeklerde ventro-dorsal kalça görüntülenmesinde norbergs açısı üzerine etkileri
No full textTwo radiographic distraction techniques (Standard Ventrodorsal Hip-Extended Radiography, SHER, and
Balanced Hip-Extended Radiography, BHER) were evaluated for Canine Hip Dysplasia (CHD) diagnosis on 100
hip joints of 50 dogs to determine the most reliable method in the detection of higher hip laxity employing
Norbergs-Olsson angle (NoA) evaluation (FCI hip scoring). Anesthesia was standardized due to uniformity in
muscle relaxation and applied to extend loads (SHERKg and BHERKg) were measured on hind legs using
electronic weight scales (EWS) simultaneously with ventrodorsal (V/D) radiography. Results of NoA scores were
evaluated statistically together with weight scale (WS) values. Significant differences were found between groups
of methods for both in WS results (p<.001) and NoA evaluations (p<.001). The difference between right and left
sides in WS results was not found significant (p>.05). Even if there was no significant difference occurred in this,
balancing the loads with the BHER method caused a significant difference in NoA values between tested
methods (p<.001). Moreover, the linear, positive, and strong correlation between SHER and BHER methods was
shown the reliability of the BHER method in NoA evaluations (rs= .910, p<.001). In conclusion, by having a
positive and strong correlation with the standard method, and better outcomes in FCI hip scoring with lower
misdiagnose frequency thus affecting the clinical outcome, the BHER method was offered as a reliable method in
the diagnosis of CHD.İki radyografik distraksiyon tekniği (Standart, SHER ve Dengelenmiş Radyografi, BHER) köpek kalça
displazisinin değerlendirilmesinde 50 köpeğin 100 kalça ekleminde değerlendirildi ve sonuçlar Norberg-Olsson
(NoA) açı derecesi temelinde ele alındı (FCI skorlama). Anestezik yöntem kas gevşemesi yönünden standardize
uygulandı. Arka ayaklara uygulanan çekme kuvvetleri (SHERKg ve BHERKg) radyografiler sırasında elektronik
yük ölçer (WS) alet vasıtası ile ölçüldü. NoA ölçüm sonuçları yük ölçer sonuçları birlikte istatistiksel yönden
değerlendirildi. NoA açısı (p<.001) ve WS sonuçlarında gruplar arasında istatistiksel yönden anlamlı sonuçlar
belirlendi. WS sonuçlarında sağ ve sol ayak tarafları arasında fark belirlenmedi (p>.05). BHER metodunda
kullanılan dengeleyici çekme kuvveti sonucunda NoA ölçümlerinde anlamlı farklılık oluştuğu görüldü (p<.001).
SHER ve BHER metodları arasında istatistiksel yönden lineer, pozitif ve güçlü bir korrelasyon bulunması BHER
metodunun güvenilirliği yönünde değerlendirildi (rs= .910, p<.001). Karar aşamasında; uygulanan BHER
metodunun FCI skorlaması yönünden daha az yanlış tanı bulgusu göstermesi neticesinde klinik aşamada köpek
kalça displazisinin belirlenmesinde güvenilir bir metod olduğu ve meslektaşlarımıza önerilebileceği sonucuna
varıldı
A propos des origines du « style animalier »
No full textThe Author, who is Professor of archaeology and a specialist of rock art in Central Asia examines the various theories about the origin of the scytho-siberian animal style. Prof. Sher refutes the theory of Middle Eastern origin, principally based on the discovery of the so-called « Ziwiye hoard ». Furthermore, the scientific excavation of the kurgan Arzhan (Tuva) offers strong evidence for an early datation (between 12th and 9th centuries B.C.) for the representations of the first period of this animal style, contemporary to the Karasuk culture (Late Bronze, Early Iron Age). These representations, on rock, as well as on stelae (the « deer stelae ») and artefacts, are rooted in the Early Bronze Age representations of the Okunevo and Afanasevo cultures in the Minusinsk basin and neighbouring areas. Prof. Sher traces some stylistic elements and their evolution from South Siberia towards Central Asia and further West, where they meet Middle Eastern influences.Sher Jakov A.

ABSTRACT
The experiment was carried out in the Department of Plant Pathology of Sher-e-Bangla Agricultural University, Dhaka during the period of January, 2012 to August, 2012 to determine the prevalence of seed borne bacteria of hybrid maize variety NK-40 and their management with some selected Cu-fungicides. Three bacterial genera viz. Acidovorax sp, Burkholderia sp and Ralstonia sp were isolated from maize seeds. Moreover, three Cu-fungicides viz. Sulcox 50WP, Champion 50WP and Cupravit 50WP were used as treatments for management. Bioassay of these fungicides against different bacteria were done and observed that Sulcox 50WP @ 0.3%, Champion 50WP @ 0.4% and Cupravit 50WP @ 0.3% produced remarkable inhibition zone against Acidovorax sp, Burkholderia sp and Ralstonia sp. Effect of seed treatments were studied using nutrient agar plate method, water agar test tube method and rolled paper towel method. In nutrient agar plate method, germination varied from 94.83-98.67%, where the effect of Cu-fungicides was insignificant. In water agar test tube method, the highest number of normal seedlings (69.00%) were recorded when seeds were treated with Cupravit 50WP @ 0.3% and the lowest was recorded in control (44.67%). The lowest number of abnormal seedlings and diseased seedlings (20% and 5%, respectively) were recorded when the seeds were treated with Cupravit 50WP @ 0.3%. In rolled paper towel method, Cupravit 50WP @ 0.3% showed best performance regarding germination, shoot length, root length and vigor index. The vigor index varied from 885.50-2488.40, where the highest count was recorded in Cupravit 50WP @ 0.3% and lowest in control
Associative linking for collaborative thinking: Self-organization of content in online Q&A communities via user-generated links.
No full textVirtual collaborative Q&A communities generate shared knowledge through the interaction of people and content. This knowledge is often fragmented, and its value as a collective, collaboratively formed product, is largely overlooked. Inspired by work on individual mental semantic networks, the current study explores the networks formed by user-added associative links as reflecting an aspect of self-organization within the communities' collaborative knowledge sharing. Using eight Q&A topic-centered discussions from the Stack Exchange platform, it investigated how associative links form internal structures within the networks. Network analysis tools were used to derive topological indicator metrics of complex structures from associatively-linked networks. Similar metrics extracted from 1000 simulated randomly linked networks of comparable sizes and growth patterns were used to generate estimated sampling distributions through bootstrap resampling, and 99% confidence intervals were constructed for each metric. The discussion-network indicators were compared against these. Results showed that participant-added associative links largely led to networks that were more clustered, integrated, and included posts with more connections than those that would be expected in random networks of similar size and growth pattern. The differences were observed to increase over time. Also, the largest connected subgraphs within the discussion networks were found to be modular. Limited qualitative observations have also pointed to the impacts of external content-related events on the network structures. The findings strengthen the notion that the networks emerging from associative link sharing resemble other information networks that are characterized by internal structures suggesting self-organization, laying the ground for further exploration of collaborative linking as a form of collective knowledge organization. It underscores the importance of recognizing and leveraging this latent mechanism in both theory and practice

No full text The ephemeral placenta provides a noncontroversial source of young, healthy cells of both maternal and fetal origin from which cell therapy products can be manufactured. The 2 advantages of using live cells as therapeutic entities are: (a) in their environmental-responsive, multifactorial secretion profile and (b) in their activity as a “slow-release drug delivery system,” releasing secretions over a long time frame. A major difficulty in translating cell therapy to the clinic involves challenges of large-scale, robust manufacturing while maintaining product characteristics, identity, and efficacy. To address these concerns early on, Pluristem developed the PLacental eXpanded (PLX) platform, the first good manufacturing practice–approved, 3-dimensional bioreactor-based cell growth platform, to enable culture of mesenchymal-like adherent stromal cells harvested from the postpartum placenta. One of the products produced by Pluristem on this platform is PLX-R18, a product mainly comprising placental fetal cells, which is proven in vivo to alleviate radiation-induced lethality and to enhance hematopoietic cell counts after bone marrow (BM) failure. The identified mechanism of action of PLX-R18 cells is one of the cell-derived systemic pro-hematopoietic secretions, which upregulate endogenous secretions and subsequently rescue BM and peripheral blood cellularity, thereby boosting survival. PLX-R18 is therefore currently under study to treat both the hematopoietic syndrome of acute radiation (under the US Food and Drug Administration [FDA]’s Animal Rule) and the incomplete engraftment after BM transplantation (in a phase I study). In the future, they could potentially address additional hematological indications, such as aplastic anemia, myelodysplastic syndrome, primary graft failure, and acute or chronic graft versus host disease. </jats:p
