Measurement of spin-orbital angular momentum interactions in relativistic heavy-ion collisions

2020

The first evidence of spin alignment of vector mesons ($K^{*0}$ and $\phi$) in heavy-ion collisions at the Large Hadron Collider (LHC) is reported. The spin density matrix element $\rho_{00}$ is measured at midrapidity ($|y| <$ 0.5) in Pb-Pb collisions at a center-of-mass energy ($\sqrt{s_{\rm NN}}$) of 2.76 TeV with the ALICE detector. $\rho_{00}$ values are found to be less than 1/3 (1/3 implies no spin alignment) at low transverse momentum ($p_{\rm T} <$ 2 GeV/$c$) for $K^{*0}$ and $\phi$ at a level of 3$\sigma$ and 2$\sigma$, respectively. No significant spin alignment is observed for the $K^0_S$ meson (spin = 0) in Pb-Pb collisions and for the vector mesons in $pp$ collisions. The meas…

Probing the Effects of Strong Electromagnetic Fields with Charge-Dependent Directed Flow in Pb-Pb Collisions at the LHC

2020

The first measurement at the LHC of charge-dependent directed flow ($v_{1}$) relative to the spectator plane is presented for Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV. Results are reported for charged hadrons and $\rm D^{0}$ mesons for the transverse momentum intervals $p_{\rm T}>0.2$ GeV/$c$ and $3<p_{\rm T}<$ 6 GeV/$c$ in the 5-40% and 10-40% centrality classes, respectively. The difference between the positively and negatively charged hadron $v_{1}$ has a positive slope as a function of pseudorapidity $\eta$, ${\rm d}\Delta{v_1}/{\rm d}\eta=$[1.68 $\pm$ 0.49 (stat.) $\pm$ 0.41 (syst.)] $\times 10^{-4}$. The same measurement for $\rm D^{0}$ and $\rm\bar{D}{}^0$ mesons yields a p…

Validation of a Short Form of Job Crafting Scale in a Spanish Sample

2018

AbstractApplications of job crafting are widespread in the professional practice. In an attempt to measure this phenomenon, Tims, Bakker and Derks (2012) developed a Job Crafting Scale based on the Job Demand-Resources model (JD-R) and validated it in a Dutch sample. However, its application to other cultural contexts presented some difficulties. The present work aimed to validate a shorter version of scale by Tims et al. (2012) in a Spanish sample (n = 1,647). The data were randomly split in two independent subsamples (Sample 1: Explorative; Sample 2: Confirmative). The exploratory factor analysis showed a three-factor structure. Through a confirmatory factor analysis, the four-dimensional…

The Factorial Structure of the Outcome Questionnaire-45: A Study with an Italian Sample.

2008

In this article, the authors study the factorial structure of the Italian translation of the Outcome Questionnaire 45 (OQ-45) in a sample of college students (n = 522) and psychiatric outpatients (n = 301). The relative goodness of fit of six competing models of the OQ-45 was examined using confirmatory factor analysis (CFA). Specifically, the study examined the relative fit of the most frequently presented models in the literature and three alternative models. Results of the CFA provided support for the four factor bi-level solution, suggesting that the OQ-45 is a multidimensional instrument that contains one general factor and multiple unique subscale factors.

Neural Network for Estimating Energy Expenditure in Paraplegics from Heart Rate

2014

The aim of the present study is to obtain models for estimating energy expenditure based on the heart rates of people with spinal cord injury without requiring individual calibration. A cohort of 20 persons with spinal cord injury performed a routine of 10 activities while their breath-by-breath oxygen consumption and heart rates were monitored. The minute-by-minute oxygen consumption collected from minute 4 to minute 7 was used as the dependent variable. A total of 7 features extracted from the heart rate signals were used as independent variables. 2 mathematical models were used to estimate the oxygen consumption using the heart rate: a multiple linear model and artificial neural networks…

Rasisms un noziegumi Voltera Moslija detektīvromānos "Velns zilā kleitā", "Sarkanā nāve" un "Balts tauriņš"

2019

Bakalauradarbs „Rasisms un kriminālsVolteraMoslijadetektīvromānos „Velnszilākleitā”, „Sarkanānāve” un „Baltstauriņš”” analizēnosauktus romānus ar uzsvaru uz aprakstītas kriminālas situācijas un rasismu ASV kopumā un Kalifornijā. Ņemot vērā ka romāni pieder pie daiļliteratūras un autora situācijas redzējums var atšķirties no reālas situācijas ASV četrdesmitajos un piecdesmitajos gados, ir savākta un apkopota informācija par rasisma un segregācijas vēsturi ASV, lai izprastu, cik patiess priekšstats par situāciju autors dod. Bakalaura darba mērķis ir atrast rasisma un segregācijas piemērus romānos; saprast, kā atrastie piemēri ilustrē rasisma, augstu ieslodzīto un apsūdzēto afroamerikāņu īpats…

"Negritude" kā sociokulturāla parādība Leopolda Sedara Senghora tekstos "Dziesmu ēnu". Semantiskā pieeja

2019

Šis pētījums ir veltīts Négritude fenomenam un afrikaņu literatūras dzimšanai 20.gadsimta sākuma. Pēc gadsimtiem ilgas sociālās nevienlidzības un verdzības afrikāņi atrada Jauno afrikaņu filozofiju, kas kļuva par afrikaņu humanisma sākumu. Afrikāņu dabas, kultūras tradīciju un melnās Āfrikas estētikas pētījums ir bbalstīts tagadējā pētījumā no dzejoļu krājuma „Dziesmu ēnu”tekstiem. Sekojošā metode tiek realizēta, pateicoties izvēleta semantisko lauku analīzei.
