No full textIntrinsic contractivity for some non-symmetric Lévy processes with non-local operators
No full textIn this thesis we consider two types of non-symmetric processes, which are similar to the symmetric α-stable process. We derive sharp estimates for the eigenfunctions of the Feynman- Kac semigroups of these two types of processes and established their intrinsic contractivities. Our methods are mainly probabilistic and depend essentially on the sharp estimates of heat kernels.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2018-08-01The student, Qu Lu, accepted the attached license on 2016-07-11 at 15:10.The student, Qu Lu, submitted this Dissertation for approval on 2016-07-11 at 15:26.This Dissertation was approved for publication on 2016-07-12 at 09:47.DSpace SAF Submission Ingestion Package generated from Vireo submission #9871 on 2016-11-10 at 12:25:09Made available in DSpace on 2016-11-10T18:42:55Z (GMT).

A Profile of Fatherhood Among Young Men: Moving Away from Their Birth Family and Closer to Their Child.
No full textHave things changed all that much in terms of how fatherhood is conceptualized and exercised in daily life? That is the question underlying this article. The author compares the findings of a recent analysis on certain aspects of the lived experiences of young fathers (under 25 years of age) with the results of studies undertaken over the past ten years, and replies in the affirmative. First of all, when considering the representations held of fathers or mothers, most of these young fathers believe that their role is a multi-faceted one, and that it is often identical to that of their spouse. According to young fathers, fatherhood is a dual experience that requires them to be present on a daily basis while also casting their eye on the future. This is an experience that is constructed out of affectionate moments, child-care duties, education in the literal sense, and especially out of shared experiences with their spouse. In addition, they question the degree to which involvement in a career should take precedence over involvement in their child's life. In other words, the former 'competes' with their ability to be present in their child's daily life, which denotes a change from the attitudes of previous generations.Fatherhood, Young Fathers, Representation, Paternal Identity, Qualitative Research
Electrophysiological correlates of adjustment process in anchoring effects
No full textAnchoring is a judgmental bias that final judgments are assimilated toward the starting point of the judge's deliberations. The anchoring-and-adjustment heuristic holds that anchoring bias is caused by insufficient adjustment. With the manipulation of some subjective factors, previous research found that anchoring is an effortful process. However, there is little evidence supporting that the effortful process is an adjustment process. In the present work, number accuracy was introduced as an objective factor which involves in an adjustment process. An event-related brain potential (ERP) experiment on young normal subjects examined the impact of number accuracy on anchoring processes responding to anchors which were generated by subjects themselves. A dot-image paradigm was firstly employed to explore anchoring effects. Behavioral results found less accurate anchors which determined a coarser mental scale diminished the anchoring biases responding to self-generated anchors. A positive deflection at 250-800 ms after target onset can be taken as a direct electrophysiological evidence of the adjustment process, whose amplitude was more positive on more accurate anchors condition. The present results further support that people adjust upwards or downwards on a mental scale from the self-generated anchor, which is consistent with the adjustment heuristics.Anchoring is a judgmental bias that final judgments are assimilated toward the starting point of the judge's deliberations.

CAMBIOS QU\ucdMICOS CAUSADOS POR ENCALADO EN SUELOS TROPICALES
No full textFueron aplicados cuatro niveles de tratamiento (0,5 - 1,0 - 1,5 y 2,0 meq Ca/100 g suelo) a cuatro ultisoles \ue1cidos. Las evaluaciones fueron realizadas para determinar el tratamiento m\ue1s eficiente para neutralizar el aluminio cambiable. Se utiliz\uf3 carbonato de calcio (grado reactivo) como material de encalado.

ABSTRACT
Four treatment lev\ue9is (0.5,1.0,1.5 and 2.0 meq. Ca/100 g. soil) were applied to four ultisol acid soils. Evaluations were designed to determine the most efficient treatment for neutralizing the exchangeable aluminum. Calcium carbonate (reagent grade) was used as liming material. Liming effects were evaluated by determining the changes in chemical characteristcs in each one of soils at 3,6 and 9 weeks after application. Increases in soil pH and calcium content were observed with an increase of treatment lev\ue9is. Magnesium decreased with the time after application.
Exchangeable aluminum was significantly decreased at low lev\ue9is of calcium carbonate. We found an exchangeable aluminum valu\ue9 of 0.200 meq/lOOg. soil as an optimal level that be reached in liming soils, corresponding to soil pH val\ufaes near 5.3 and a time period incubation of six week.

Previous issue date: 2018Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior (CAPES)O cultivo das esp?cies de pitaia no Brasil teve aumento na ?ltima d?cada e, em fun??o disso, t?m-se buscado informa??es relacionadas ao manejo dos pomares, para que seja poss?vel alcan?ar altas produtividadese frutas com qualidade comercial. Para isso, a pr?tica da calagem ? fundamental, considerando os tipos de solo cultivados no Brasil, que s?o ?cidos, em sua maioria. Esta pesquisa foi desenvolvida com o objetivo de avaliar a necessidade de calagem para determinar a satura??o de alum?nio tolerada, a satura??o por bases desejada e o requerimento de c?lcio e magn?sio para o cultivo das esp?cies de pitaia Hylocereus undatus e H. polyrhizus. A pesquisa foi realizada em dois tipos de solo diferentes, o Neossolo Quartzar?nico e o Latossolo Vermelho Amarelo distr?fico, estudados em dois experimentos. Os experimentos foram conduzidos casa de vegeta??o, organizados em esquema fatorial 2 x 4, sendo duas esp?cies de pitaia, H. undatus e H. polyrhizus e quatro necessidades de calagem, 0; 0,8; 1,2 e 1,7 t ha-1, para Neossolo e 0; 1,3; 2,0 e 2,8 t ha-1, para Latossolo, distribu?dos em blocos casualizados, com cinco repeti??es. A calagem foi realizada com calc?rio dolom?tico para elevar a satura??o por bases desejada a partir da satura??o de bases inicial dos solos. A calagem elevou o pH, aumentou os teores de K, Ca e Mg, a satura??o de Ca, a satura??o de Mg e a satura??o por bases nos solos. Os teores de P, Ca e Mg aumentaram e os teores de N, K, Zn, Mn e Fe diminu?ram, nas brota??es das duas esp?cies de pitaia, com o aumento da quantidade de calc?rio aplicada. As necessidades de calagem para a maior produ??o de mat?ria seca nas duas esp?cies de pitaia foi de 1,7 t ha-1, no Neossolo e de 1,9 t ha-1, para a esp?cie H. polyrhizus e de 2,8 t ha-1 para a esp?cie H. undatus cultivadas em Latossolo. A calagem ? uma pr?tica que deve ser realizada para o cultivo das esp?cies de pitaia em solos ?cidos para elevar o pH, a satura??o por bases, reduzir a satura??o de alum?nio e adequar o requerimento de c?lcio e de magn?sio. As esp?cies H. undatus e H. polyrhizus cultivadas em Latossolo Vermelho Amarelo distr?fico apresentam maior crescimento quando a satura??o de alum?nio no solo est? entre 1% e 4%, satura??o por de bases entre 55% e 70% e requerimento de c?lcio e magn?sio em 3,0 cmolcdm-3. As esp?cies de pitaia cultivadas em Neossolo Quartzar?nico apresentam maior crescimento quando a satura??o de alum?nio no solo est? entre 13% e 16%, a satura??o por bases em 70% e o requerimento de c?lcio e magn?sio em 2,5 cmolc dm-3. A acidez do solo interfere no crescimento das esp?cies de pitaia, que preferem solos com pH entre 6,6 e 7,0. A calagem para atender ?s exig?ncias das esp?cies de pitaia deve ser realizada de acordo com os atributos qu?micos de cada tipo de solo.Disserta??o (Mestrado) ?

the last decade and we have sought information
related to orchard management in order to
achieve high productivity and commercial quality
fruits. For this, the practice of liming is fundame
ntal, considering the t
ypes of soil grown in
Brazil that are mostly acidic. This research wa
s carried out with the ob
jective of evaluating
the liming need to determine:
the tolerated aluminum saturati
on, desired base saturation, and
the requirement of calcium and magnesium
for cultivation of the pitayas pecies,
Hylocereus
undatus
and
H. polyrhizus
. The research was carried out on
two different soil types, in
Quartzarenic Neosol and Dystrophic Yellow Red
Latosol, studied in two experiments. The
experiments were conducted greenhouse, organized
in 2x4 factorial scheme ,being two pitaya
species:
H. undatus
and
H. polyrhizus
and four liming needs: 0; 0.8; 1.2 and 1.7 t ha
-1
for
Neosol and 0; 1.3; 2.0 and 2.8 t ha
-1
for Latosol, distributed in randomized blocks with five
replications. Liming was performed with dolom
itic limestone to raise the initial base
saturation to a desired base saturation of the so
ils. Liming raised the pH, increased K, Ca and
Mg contents, Ca saturation, Mg saturation and ba
se saturation in soils. The P, Ca and Mg
contents increased and N, K, Z
n, Mn and Fe contents decreased in the shoots of the two pitaya
species with the increased amount of limest
one applied. The liming requirements for the
highest dry matter production were 1.7 t ha
-1
in Neosol and 1.9 t ha
-1
for the specie
H.
polyrhizus
and 2.8 t ha
-1
for the specie
H. undatus
grown in Latosol. Fo
r the cultivation of
pitaya species in acid soils the liming is a prac
tice that must be carried out to elevate pH,
elevate base saturation, reduce aluminum satu
ration and adjust the calcium and magnesium
requirement. The species
H. undatus
and
H. polyrhizus
cultivated in Dyst
rophic Yellow Red
Latosol present higher growth wh
en the aluminum saturation in the soil is between 1% and
4%, base saturation between 55% and 70% and
the calcium and magnesium requirement in
3.0 cmol
c
dm
-3
In Quartzarenic Neosol the pitaya species presented higher growth when the
aluminum saturation in the soil is between
13% and 16%, bases satu
ration in 70% and the
calcium and magnesium requirement in 2.5 cmol
c
dm
-3
. The soil acidity interferes in the
growth of pitaya species, which prefer soil
s with pH between 6.6 a
nd 7.0. Liming to meet the
requirements of the pitaya species should be car
ried out according to the chemical properties
of each soil type
