Modeling of Fertilizer Transport for Various Fertigation Scenarios under Drip Irrigation
Authors: Elasbah Romysaa , Selim Tarek , Mirdan Ahmed , Berndtsson Ronny
Published: April 2019

Frequent application of nitrogen fertilizers through irrigation is likely to increase the concentration of nitrate in groundwater. In this study, the HYDRUS-2D/3D model was used to simulate fertilizer movement through the soil under surface (DI) and subsurface drip irrigation (SDI) with 10 and 20 cm emitter depths for tomato growing in three different typical and representative Egyptian soil types, namely sand, loamy sand, and sandy loam. Ammonium, nitrate, phosphorus, and potassium fertilizers were considered during simulation. Laboratory experiments were conducted to estimate the soils’ adsorption behavior. The impact of soil hydraulic properties and fertigation strategies on fertilizer distribution and use efficiency were investigated. Results showed that for DI, the percentage of nitrogen accumulated below the zone of maximum root density was 33%, 28%, and 24% for sand, loamy sand, and sandy loam soil, respectively. For SDI with 10 and 20 cm emitter depths, it was 34%, 29%, and 26%, and 44%, 37%, and 35%, respectively. Results showed that shallow emitter depth produced maximum nitrogen use efficiency varying from 27 to 37%, regardless of fertigation strategy. Therefore, subsurface drip irrigation with a shallow emitter depth is recommended for medium-textured soils. Moreover, the study showed that to reduce potential fertilizer leaching, fertilizers should be added at the beginning of irrigation events for SDI and at the end of irrigation events for DI. As nitrate uptake rate and leaching are affected by soil’s adsorption, it is important to determine the adsorption coefficient for nitrate before planting, as it will help to precisely assign application rates. This will lead to improve nutrient uptake and minimize potential leaching.

Published: April 2019

Water scarcity is a worldwide problem boosted by global warming and pollution of anthropogenic origin. The contaminants of emerging concern in water sources are increasing due to the inefficiency of conventional wastewater treatments, and these should be mitigated. Advanced oxidation processes appear as suitable solutions for decontamination. The photocatalytic oxidation of the mixture of sulfamethoxazole, carbamazepine and lorazepam was investigated. TiO2 modified by Ag and TiO2 modified by Pd were used as photocatalysts to improve photoactivity. The impact of light wavelengths was examined using UVA and visible radiation as well as natural sunlight. Visible light revealed the lowest ability for decontamination in 60 min of irradiation through Ag and Pd–TiO2 photocatalytic oxidation. On the other hand, UVA and sunlight in the presence of photocatalysts were able to totally remove the contaminants. This can be related to the high production of reactive oxidative species at those conditions. The increase of the noble metal load promotes the improvement of the decontamination efficiency. The kinetic rate was analyzed for UVA and sunlight radiation for different photocatalytic conditions. The presence of a natural light source without energy costs leads to an increase in the pseudo-first-order kinetic constant. Sunlight radiation with a suitable photocatalyst can be a very good option for water decontamination.

Synthetic lead oxychloride, Pb₃O₂Cl₂, is orthorhombic, Pnma : a = 11.87 Å, b = 5.806 Å, c = 9.48 Å.

There are four formula weights in the unit cell. Its atomic structure has been determined by the symbolic addition technique (Karle and Hauptman). The structure has been refined from 1,550 F[hkl] to an R value of 0.09 : the structure model proposed is analogous to that of mendipite, natural Pb₃O₂Cl₂, even though mendipite is actually described in the space group P2₁2₁2₁.
Local movements of Greylag Geese Anser anser in South Sweden during the non-breeding season
Authors: Nilsson Leif , Kampe-Persson Hakon
Published: April 2019

During 1984–2009, Greylag Geese Anser anser were neck-banded at two lakes six kilometres apart in south-west Scania, southernmost Sweden: 2,308 at lake Yddingen and 633 at Klosterviken (part of lake Börringe). Through 2013 we recorded 51,132 and 29,937 resightings, respectively. We analyse the distribution patterns within Scania during the post-breeding months July–March. In spite of the short distance between the breeding sites, marked differences in the local distributions were found. In late summer and early autumn, Greylags from Klosterviken stayed longer inland close to the breeding lake than geese from Yddingen, the availability of good inland feeding sites close to Klosterviken explained the difference. In late autumn, when many resightings were made along the western coast, it seemed that the distance from the breeding lake explained some of the differences, geese from Yddingen dominated in the northern part, whereas geese from Klosterviken were found further south. There was also a time difference in that the birds from Yddingen moved to the coast earlier than those from Klosterviken.
Hanöbukten, an important wintering area for waterbirds in South Sweden
Authors: Nilsson Leif , Olsson Mats
Published: April 2019

Hanöbukten in SE Sweden (including Blekinge archipelago) is an important wintering and staging area for a number of waterbird species. The inshore parts have been covered by counts from the shore during the International Waterbird Counts (IWC) since 1969. In the present study we analyze these counts for the period 1969–2014. When the counts started the total number of wintering waterbirds varied between 20,000 and 40,000 per year. However, from the early 1990s the number doubled, reaching 60,000 to 80,000 birds per year. All species with the exception of the Long-tailed Duck Clangula hyemalis showed similar increase. The area had a high proportion of the Swedish wintering population of Pochard Aythya ferina and Smew Mergellus albellus. Large numbers of Tufted Duck Aythya fuligula also wintered in the area, and some parts of the archipelago had internationally important concentrations of Tufted Duck and Smew. The increase in numbers in the study area showed the same pattern as in all Sweden and was most probably a result of milder winters in recent years.
Are large fields of autumn wheat at Kvismaren, central Sweden, used as nesting and food search habitats by Skylarks Alauda arvensis?
Authors: Sondell Jan
Published: April 2019

The skylark Alauda arvensis population has declined in Sweden. The breeding in silage ﬁelds fails and the success in autumn crops is disputed. Therefore, I decided to study the skylark utilisation of autumn crop ﬁelds in Kvismaren, central Sweden. The largest accessible ﬁeld was selected (40 ha) to get as tough conditions as possible for foraging. I could conclude that the nests were evenly placed, the youngsters developed normally and the occupancy was about 80 pairs or territories per km2. The skylarks searched for food as much inside as outside the large breeding ﬁeld. The ﬂight distances were on average 204 m and up to 550 m. The conclusion was that autumn crops are probably as good as spring crops regarding breeding habitat; potentially even better as the offspring ﬂedged at least 1‒2 weeks earlier. One potential positive factor for the breeding was the occurrence of unsown tractor tracks (tramlines, 2.5% of the area) which were frequently utilised by the skylarks. Such tracks are commonly created nowadays in Sweden and may replace otherwise desired skylark plots.
How many observation days are needed to reliably describe bird migration?
Authors: Tanskanen Antti , Yrjölä Rauno A , Baum Ulrike , Tanskanen Sakari , Eriksson Jörgen
Published: April 2019

The total number of migrating birds is needed, for example, to estimate collisions risk as part of the assessment process for wind-power parks. This estimation is often based on a small sample of observation days, making estimates uncertain. To determine the number of days needed to obtain reliable figures we used observations of migrating birds obtained from the Signilskär bird observatory, Åland, Finland during the autumn seasons from 2009 to 2013. We sampled 1–14 days during each 14 day time window and used linear extrapolation and Poisson regression with weather covariates to estimate the total number of migrating birds and distribution of estimates. We calculated the head-wind and side-wind components according to the species’ most common flight directions. We found that observations should cover at least 90% of the migration period to obtain precise results and 70–90% to obtain results sufficiently reliable to use in practice. Linear extrapolation is the best model for small samples. The larger the proportion of days observed, the better is Poisson regression with weather covariates.
Winter recovery in Sweden of a Dutch Blackcap Sylvia atricapilla
Authors: Tengholm Anders , Tengholm Johan , Ekblom Robert
Published: April 2019

In February 2018, a European Blackcap Sylvia atricapilla that had been ringed as a yearling in the Netherlands in the previous autumn was trapped in Uppsala, Sweden (59.8°N). Winter records of Blackcaps are not uncommon in Sweden but this is the first recovery of a bird with documented southern origin. The finding is in line with reports that a relatively high proportion of ringed Blackcaps is recovered in the same autumn north of the ringing site, and that the fraction of short-winged Blackcaps of presumed southern origin increases late in the season at Swedish bird observatories. Although the present record provides evidence that Blackcaps wintering in Sweden may originate from Continental Europe, it appears unlikely that the Blackcap will be able to evolve a new migration pattern, similar to the population of Continental Blackcaps wintering in Britain, because few Blackcaps seem to survive the Swedish winter.

Published: April 2019

Discuss about the principles of classification of medical waste and the situations in which the waste are not subject to regulations of ADR. Pointed out ways to transport this waste: in packages and in loose. Attention was paid to the lack on the Polish market of appropriate packaging and it's high price. Transport in loose was discussed in detail paying attention to similarities and differences in the requirements in transport based on regulations BK2 i VC3. VC3 requires that national authorities determine conditions of transport - until now such rules do not exist. The illustrations show some examples of inappropriate transport. It was noted that the inspection services have a problem with understanding binding laws.
Extending transition curve in analytical design method
Authors: Koc Władysław
Published: April 2019

The paper presents the problem of extending the transitional curves, using for this purpose an analytical design method. The basis for the analysis of numerical calculations were carried out for a wide set of parameters characterizing the standard geometric system. We considered an importance of the size of radius of the circular arc and return angle of route on the obtained results after the formulation of appropriate theoretical dependence. It was found that the extension of the transition curve does not need cause large lateral displacements of the existing track at considerable length. It is only necessary to reduce the radius of the circular arc in a suitable way.

Published: April 2019

Background: Improved treatments resulting in a rising number of survivors of breast cancer (bca) calls for optimization of current specialist-based follow-up care. In the present study, we evaluated well survivors of bca with respect to their supportive care needs and attitudes toward follow-up with various care providers, in varying settings, or mediated by technology (for example, videoconference or e-mail). Methods: A cross-sectional paper survey of well survivors of early-stage pT1–2N0 bca undergoing posttreatment follow-up was completed. Descriptive and univariable logistic regression analyses were performed to examine associations between survivor characteristics, supportive care needs, and perceived satisfaction with follow-up options. Qualitative responses were analyzed using conventional content analysis. Results: The 190 well survivors of bca who participated (79% response rate) had an average age of 63 ± 10 years. Median time since first follow-up was 21 months. Most had high perceived satisfaction with in-person specialist care (96%, 177 of 185). The second most accepted model was shared care involving specialist and primary care provider follow-up (54%, 102 of 190). Other models received less than 50% perceived satisfaction. Factors associated with higher perceived satisfaction with non-specialist care or virtual follow-up by a specialist included less formal education (p < 0.01) and more met supportive care needs (p < 0.05). Concerns with virtual follow-up included the perceived impersonal nature of virtual care, potential for inadequate care, and confidentiality. Conclusions: Well survivors of bca want specialists involved in their follow-up care. Compared with virtual followup, in-person follow-up is perceived as more reassuring. Certain survivor characteristics (for example, met supportive care needs) might signal survivor readiness for virtual or non-specialist follow-up. Future work should examine multi-stakeholder perspectives about barriers to and facilitators of shared multimodal follow-up care.
Factors Influencing Surgical Treatment Decisions for Breast Cancer: A Qualitative Exploration of Surgeon and Patient Perspectives

Published: April 2019

Background: The rate of mastectomy is much higher in Newfoundland and Labrador than in any other province in Canada, even for women diagnosed at an early stage. In this paper, we present qualitative data from women who have made a decision for surgical treatment and from breast surgeons in an effort to better explicate factors influencing breast cancer (BCA) surgical decision-making. Methods: The study’s descriptive, qualitative design involved holding interviews with breast surgeons and holding focus groups and interviews with women who were offered the choice of breast-conserving surgery (BCS) or mastectomy (MT). Results: Participants included 35 women and 13 surgeons. High interest in MT and increasing requests for prophylactic contralateral MT were evident. A host of factors—clinical, demographic, psychosocial, education-related, and cultural—influenced the decisions. A key factor for women was fear of recurrence and a need to “just get rid of it,” but the experiences of others also influenced the decisions. Life stage and family considerations also factored prominently into women’s decisions. Conclusions: Women with early-stage BCA more often chose MT and often demanded prophylactic removal of the healthy breast. Findings highlight the importance of ensuring that women at average risk are appropriately counselled about the low likelihood of a subsequent contralateral BCA and the lack of survival benefit associated with prophylactic contralateral MT. Findings also revealed other areas of presurgical discussion that might help women think through their personal circumstances and values so as to encourage informed surgical decisions.
Lazarus-Type Tumour Response to Therapy with Nivolumab for Sarcomatoid Carcinomas of the Lung
Authors: Roesel C. , Kambartel K. , Kopeika U. , Berzins A. , Voshaar T. , Krbek T.
Published: April 2019

Pulmonary sarcomatoid carcinoma (PSC) is a rare subtype of non-small-cell lung carcinoma with a poor prognosis and poor response to chemotherapy and radiotherapy. A previous study reported that psc expresses high levels of PD-L1, suggesting the potential efficacy of immune checkpoint inhibitors in these tumours. We report 2 cases of patients with a lung sarcomatoid carcinoma. Both patients initially underwent curative lung resection, but developed early recurrent disease. Because PD-L1 was highly expressed in the tumour cells, we initiated therapy with nivolumab, which showed good efficacy, almost complete radiologic tumour remission, and a remarkable improvement in the condition of those patients. Immune checkpoint inhibitors targeting PD-1 might be a valuable therapy option for PSCS.

Published: April 2019

Background: Data showing the value of neoadjuvant chemotherapy (NACT) followed by interval debulking surgery (IDS) in the management of advanced-stage serous endometrial carcinoma (ECA) are limited; the aim of the present study was to expand the knowledge about that treatment strategy in patients with advanced ECA, including endometrioid ECA. Methods: Data were collected retrospectively from all patients with advanced-stage eca treated with NACT between 2005 and 2014 at 3 oncology referral centres. Primary outcomes were the radiologic response to nact and achievement of optimal or complete IDS. Secondary outcomes were recurrence rate and progression-free and overall survival. Results: Of 102 ECA cases included, a complete radiologic response was achieved in only 4 cases, with a partial response being achieved in 72% (64% of endometrioid cases, 80% of serous cases). Complete IDS was achieved in 62% of the endometrioid cases and in 56% of the serous ECA cases, with optimal IDS achieved in 31% and 28% of those cases respectively. Survival rates were calculated for all patients with complete and optimal IDS; recurrence was observed in 56% and 67% of the cases respectively, and progression-free survival was 18 months and 13 months respectively. Median survival duration was 24 months for endometrioid ECA and 28 months for serous ECA. Conclusions: For patients with advanced ECA who are not suitable for primary debulking, NACT followed by IDS can be considered regardless of histologic subtype. The treatment options for this group of patients are limited and have to be explored.
Moving toward the Elimination of Cervical Cancer: Modelling the Health and Economic Benefits of Increasing Uptake of Human Papillomavirus Vaccines
Authors: Smith A. , Baines N. , Memon S. , Fitzgerald N. , Chadder J. , Politis C. , Nicholson E. , Earle C. , Bryant H.
Published: April 2019

Background: The human papillomavirus (HPV) is a common sexually transmitted infection and a primary cause of cervical cancer. The Government of Canada has set a target of reaching 90% HPV vaccine coverage among adolescents by 2025. Here, we examine HPV vaccine uptake in school-based immunization programs across Canada and explore how achieving the 90% target could affect the future incidence of cervical cancer, mortality, and health system expenditures in a cohort of Canadian women. Methods: Data for HPV vaccine uptake in the most recent reported school year available in each jurisdiction were provided in 2017 by jurisdictional school-based immunization programs and were used to estimate a national weighted average of 67%. The OncoSim microsimulation model (version 2.5) was used to compare 3 different levels of HPV vaccine uptake (0%, 67%, 90%) on health and economic outcomes for a hypothetical cohort of all 5- to 10-year-old girls in Canada in 2015. Results: Vaccine uptake for girls in school-based programs varied from 55.0% to 92.0% in the jurisdictions reviewed. The OncoSim model projects that increasing uptake to 90% from 67% would result in a 23% reduction in cervical cancer incidence rates (to 3.1 cases from 4.0 cases per 100,000, averaged across the lifetime of the cohort) and a 23% decline in the average annual mortality rate (to 1.0 deaths from 1.3 deaths per 100,000). Finally, the model projects that the health system will incur a cost of $9 million (1% increase) during the lifetime of the cohort if uptake is increased to 90% from 67%. Costs are discounted (1.5%) and expressed in 2016 Canadian dollars. Costs reflect the payer perspective. Conclusions: Our model shows that increasing HPV vaccine uptake to 90% from current levels for girls in school-based immunization programs could result in substantial reductions in the future incidence and mortality rates for cervical cancer in Canada.

A procedure is presented to improve on measurement of total H i fluxes for extended sources in the Arecibo Legacy Fast Arecibo L-band Feed Array (ALFALFA) survey of neutral hydrogen sources in the nearby universe. A number of tests of the procedure are detailed, and we verify that we recover all of the flux measured with much larger telescope beams. Total fluxes are reported for all sources (1) exceeding 10 Jy km s−1 in the α.100 catalog, or (2) with Uppsala General Catalog diameters 3.0 arcmin or more, or (3) ALFALFA pipeline isophotal ellipse area more than 3.0 times the Arecibo beam. Total fluxes are also provided for a number of confused pairs and small groups including one or more of those high-flux sources. These data should be of use in baryonic Tully–Fisher studies and other applications where the measurement of the total reservoir of neutral atomic gas is important.

Recent analyses of the excess of gamma-ray radiation emanating from the Galactic center (GC) region suggest an origin in a population of thousands of undetected millisecond pulsars (MSPs). We have conducted a search for pulsar candidates using new high-sensitivity, wide-field radio observations of the GC covering 5 deg2. We conducted the search at a low frequency of ∼320 MHz in order to take advantage of the very steep spectra typical of pulsars. Additional observations at 6 GHz of the most steep-spectrum, compact sources resulted in a list of seven candidate pulsars. No pulsations were detected for any of the candidates in a search conducted with the GBT at 1.5, 2, and 6 GHz, presumably due to severe temporal scattering in the GC region or along the line of sight. We discuss the implications of the nondetections on pulse period and distance estimates using two different models of the Galactic distribution of ionized gas. For our best candidate, C1748−2827, located 43′ from Sgr A*, we estimate that pulsations from a normal pulsar would have been detected up to a distance of ∼8 kpc and from an MSP up to ∼4.5 kpc.
Dwarfs under dinosaur legs: a new millipede of the order Callipodida (Diplopoda) from Cretaceous amber of Burma
Authors: Stoev Pavel , Moritz Leif , Wesener Thomas
Published: April 2019

The entire Mesozoic Era is rather poor in millipede (class Diplopoda) fossils, with less than a dozen species being taxonomically described. Here, we describe the first fossil millipede of the order Callipodida,Burmanopetaluminexpectatumgen. nov. et sp. nov., found in early Cenomanian amber of Burma, 98.79±0.62 Mya. The species possesses a number of morphological traits that exclude it from all extant suborders, and Burmanopetalidea suborder nov. and Burmanopetalidae fam. nov. are here erected to accommodate it. The new suborder can be recognized by the following unique characters: pleurotergal setae absent; telson with a specific spatulate shape twice the size of the penultimate body ring; hypoproct devoid of setae; and eyes composed of five well-separated ommatidia. While the callipodidan habitus seems to have remained generally unchanged for at least 99 million years, pleurotergal and hypoproctal setation, as well as the complexity of eyes in ground-dwelling forms may have evolved recently in the order. AsB.inexpectatumgen. nov. et sp. nov.is the first true callipodidan in the fossil record, the minimum age of Callipodida is thus at least 99 Mya.
Quelques images de pères dans les livres de jeunesse
Authors: Patouillot Isabelle
Published: April 2019

La question des pères, de leur place, de leur rôle dans les familles d’aujourd’hui est un axe important de réflexion de notre société. Les discours que les pères tiennent sur leur paternité́ montrent une forte implication affective auprès de leurs enfants. Ils ressentent leur rôle comme aussi important que celui de la mère et semblent gagnés au principe d’égalité́ parentale. De l’autorité à l’écoute, quelles images de pères et de nouveaux pères peut-on repérer dans le livre jeunesse ?
Allo papa, bobo ! L’appel au père à l’adolescence
Authors: Benoit Jean-Pierre
Published: April 2019

L’adolescence difficile mobilise l’entourage familial et parfois une aide extérieure, un soin, auprès des psychologues ou des psychiatres. Souvent, la personne du père est appelée au secours pour venir contenir, stimuler, répondre aux symptômes observés. Si, dans l’enfance, sa fonction paternelle est symbolique, à l’adolescence, c’est sur le versant éducatif que le père est attendu, et que ses effets sont idéalisés. Pourtant ce père appelé est en même temps celui dont on doit s’émanciper, au même titre que la mère, faisant de l’adolescence un temps paradoxal. À ce paradoxe, le père pourrait répondre par une présence et non par une maîtrise pour permettre à l’adolescent d’exprimer sa créativité sur la voie de sa propre subjectivation.
Les pères en consultation psychologique pour leur enfant : paroles de cliniciens
Authors: Castonguay Laurent , Noël Raphaële
Published: April 2019

Préalable à un projet de recherche visant une meilleure compréhension de l’engagement des pères en consultation psychologique pour leur enfant, cette recherche qualitative exploratoire s’intéresse au vécu et à l’expérience de thérapeutes d’expérience (n = 4) à propos de leur travail clinique avec les pères. La méthodologie employée est la méthode de la théorisation enracinée (ou Grounded Theory ). Huit entretiens de recherche ont été conduits auprès des quatre cliniciens puis analysés qualitativement. En plus d’identifier plusieurs spécificités et enjeux relatifs aux pères en consultation, cette étude révèle que ce sont l’expérience et le vécu cliniques des professionnels qui orientent leur travail avec les pères, et non des références à la théorie. L’ébauche d’un modèle conceptuel de la place et du rôle des pères en consultation clinique infantile est proposée, modèle dans lequel le père se positionnerait face à la dyade mère-enfant en tant que tiers relationnel en alliance avec le thérapeute.
Réflexion et expérience chez Malebranche
Authors: Geny Vincent
Published: April 2019

Le concept malebranchien de réflexion doit être distingué, d'une part, de sa conceptualisation par Descartes, d'autre part, de sa reprise par la tradition empiriste de Locke ou de Condillac. Profondément ambigu, ce concept se situe au point de jonction de l'empirique et du rationnel. Est ainsi révélée la portée véritablement empirique de certaines thèses de Malebranche, voire de l'ensemble de sa philosophie, s'il est vrai que « l'invention du problème de la réflexion est […] l'œuvre de l'empirisme » (André Charrak, Empirisme et théorie de la connaissance, Vrin, 2012, p. 20).Audrey Benoit. – Le citoyen peut‑il se passer de l'homme ? La critique des droits de l'homme de Marx et l'antihumanisme d'AlthusserDans Zur Judenfrage, Marx critique les droits de l'homme et du citoyen énoncés par les textes constitutionnels français comme instrumentalisation de l'universalité formelle de la citoyenneté, au service des intérêts réels d'une humanité réduite à sa particularité bourgeoise. Pour Althusser, qui juge que la « coupure épistémologique » séparant la préhistoire idéologique de Marx de son accès à la scientificité date de 1845, ce texte de 1843 relève encore de l'idéologie humaniste. Afin de réévaluer la lecture antihumaniste qu'Althusser fait de Marx, on montre que le texte de 1843 est déjà sous-tendu par un antihumanisme épistémologique, qui vise la construction juridique d'une double abstraction : celle du citoyen, comme figure universelle, et celle de l'homme, comme individu naturel. Ce texte témoigne de l'épistémologie politique de Marx. Une révolution problématique est ainsi à l'œuvre, dans la critique sociale de Marx.Hamid Taieb. – Que peut Freud que Brentano ne peut pas ?Dans quelle mesure l'outillage conceptuel de Brentano peut rendre compte des processus psychiques dont la découverte est usuellement attribuée à Freud ?

The objective of thinking development lesson is to help students change and develop thoughts via classroom teaching. In thinking development lessons, students will reinforce the application scenarios of their thinking skills and learn new thinking skills. For design of classroom teaching of thinking development type, thinking visualization tools are needed for organizing and guiding thinking process. In this study, a teaching design framework of thinking development lesson was developed based on mind mapping, and applied in the teaching design process of the course of Health Fitness Education. It consists of five steps, namely teaching objective setting, question situation establishment, externalization of tacit thinking, formalization of explicit thinking, and automation of efficient thinking. Teaching result check shows that the course teaching design scheme developed in this study is helpful to improve students’ learning effect in the course of Health Fitness Education significantly. This study provides a new teaching design method for teaching of Health Fitness Education, which is of important significance to helping students integrate the knowledge they have learned and rationalize thinking.
The Influence of Community Structure on the Diffusion of Knowledge—A View Based on Market Segmentation
Authors: Zheng Shi-yong , Liu Mao-hong , Huang Jin-de
Published: April 2019

To analyze the effects of different seeding selection strategies on knowledge diffusion in education field, this study builds an ABMS spreading model and performs several simulation experiments. Besides, market segmentation is proposed as the methods of community recognition as, the effects of the mechanism of market segmentation on seeding user choosing strategies are in-vestigated, and knowledge diffusion efficiency is analyzed. Given the existing education community structure in social network of knowledge, and the forma-tion mechanism of network, and even if the multiple seeds locate in the same education community, they cannot effectively exert the knowledge diffusion function of each seeding node. Several studies have showed that random selec-tion strategy is more effective than the sensitive strategy without any market segmentation. The seeding strategy integrated with market segmentation is ca-pable of improving the efficiency of knowledge diffusion significantly. In the meantime, the sensitive seeding strategy under the education community recog-nition can achieve better knowledge diffusion efficiency.
