Luokasta utopiaan : Erik Olin Wrightin myöhäistuotannosta

2020

Katsausartikkelissa tarkastellaan yhdysvaltalaisen marxilaissosiologi Erik Olin Wrightin niin sanottuihin todellisiin utopioihin kohdistunutta tutkimusta. Artikkelissa avataan sekä sitä, kuinka Wrightin todellisen utopian käsite tulisi ymmärtää, että sitä, kuinka hänen oma utopiansa eli ”sosiaalinen sosialismi” voisi olla mahdollinen ja millaiset tosimaailman kokeilut hänen mukaansa ennakoivat ja prefiguroivat tätä utopiaa. Lisäksi artikkelissa eritellään Wrightin käsityksiä antikapitalismin strategioista ja näiden myötä siitä, millä tavalla sosiaalisen sosialismin utopia olisi saavutettavissa. Artikkeli keskittyy erityisesti kahteen Wrightin myöhäistuotannon teokseen – Envisioning Real Uto…

Shear heating induced lithospheric-scale localization: Does it result in subduction?

2012

Abstract Even though it is a well-established fact that the Earth is currently in a plate-tectonics mode, the question on how to “break” lithospheric plates and initiate subduction remains a matter of debate. Here we focus on shear heating as a potential mechanism to cause lithospheric shear localization and subsequent subduction initiation in oceanic plates. It is shown that shear heating under some conditions (i) facilitates the formation of a lithospheric-scale shear zone and (ii) is capable of stabilizing a lithospheric-scale shear zone, thus creating the necessary condition for subduction initiation to occur. Furthermore, we demonstrate that not only the localization process is of impo…

Maksātnespējas prognozēšanas modeļa pielietojums Latvijas sabiedrībām ar ierobežotu atbildību

2021

Lai sadarbība starp uzņēmumiem būtu veiksmīga, katram no partneriem jābūt pārliecinātam par otra maksātspēju. Maksātnespējas prognozēšanas modeļi palīdz gūt šādu pārliecību. Izmantojot darījuma partnera deklarētos finansiālos rādītājus var gūt ieskatu tā finansiālajā stāvoklī un, pielietojot pareizi piemeklētu prognozēšanas modeli, var mēģināt savlaicīgi paredzēt iespējamo maksātnespēju. Maģistra darba mērķis ir aprobēt un pēc nepieciešamības modificēt E.Altmana Z-vērtību modeli Latvijas privāto uzņēmumu maksātnespējas paredzēšanai, salīdzināt rezultātus ar logit analīzes metodi, kā arī izstrādāt priekšlikumus modeļa plašākai pielietošanai Latvijas uzņēmējdarbības vidē. Rezultātā ar logit a…

Modelling a proportion response variable using generalised additive models for location scale and shape

2015

In this paper two alternative approaches are proposed to model a response variable Y measured on the interval from zero to one, including both zero and one. The first proposed model employs a flexible four parameter distribution for 0 < Y < 1, for example a logit skew exponential power distribution, inflated by including point probabilities at 0 and 1. The second proposed model is a generalised Tobit model, obtained from a flexible four parameter distribution on (-infinity;+infinity), for example the skew exponential power distribution, by censoring below 0 and above 1. The proposed models are applied to a real data set and compared with current popular models.

Colorectal cancer stage at diagnosis in migrants versus non-migrants (KoMigra) : study protocol of a cross-sectional study in Germany

2014

Background: In Germany, about 20% of the total population have a migration background. Differences exist between migrants and non-migrants in terms of health care access and utilisation. Colorectal cancer is the second most common malignant tumour in Germany, and incidence, staging and survival chances depend, amongst other things, on ethnicity and lifestyle. The current study investigates whether stage at diagnosis differs between migrants and non-migrants with colorectal cancer in an area of high migration and attempts to identify factors that can explain any differences. Methods/Design: Data on tumour and migration status will be collected for 1,200 consecutive patients that have receive…

A minimally invasive methodology based on morphometric parameters for day 2 embryo quality assessment.

2014

[EN] The risk of multiple pregnancy to maternal fetal health can be minimized by reducing the number of embryos transferred. New tools for selecting embryos with the highest implantation potential should be developed. The aim of this study was to evaluate the ability of morphological and morphometric variables to predict implantation by analysing images of embryos. This was a retrospective study of 135 embryo photographs from 112 IVF ICSI cycles carried out between January and March 2011. The embryos were photographed immediately before transfer using Cronus 3 software. Their images were analysed using the public program ImageJ. Significant effects (P < 0.05), and higher discriminant power …

Could Road Safety Education (RSE) Help Parents Protect Children? Examining Their Driving Crashes with Children on Board

2021

Recent evidence suggests that driving behavior and traffic safety outcomes of parents may be influenced by the extent to which they receive information and education on road safety, as well as the fact of driving with their children on board, which may increase their risk perception. However, there are no studies specifically addressing the case of crashes suffered while driving with children. Hence, this study aimed to describe the relationship between road safety education-related variables and parents’ traffic safety outcomes while driving with children on board. For this cross-sectional study, data was retrieved from a sample composed of 165 Spanish parents—all of them licensed drivers—…

Smoking Status and Severity of Ischemic Stroke. A Population-Based Study

2013

We aimed to investigate the impact of smoking status on clinical severity in patients with ischemic stroke event (IS). Patients were prospectively identified among residents of the city of Dijon, France (ca. 151,000 inhabitants), using a population-based registry, between 2006 and 2011. Demographic and clinical data were recorded. The initial clinical severity was quantified by the means of the National Institutes of Health Stroke Scale (NIHSS). Multivariable ordinal logistic regression was used to assess the effect of smoking status on severity. Among the 1,056 recorded patients with IS, data about smoking status were available for 973 (92.1%), of whom 658 (67.3%) were non-smokers, 187 (19…

Increasing early ambulation disability in spontaneous intracerebral hemorrhage survivors

2017

ObjectiveTo evaluate temporal trends in early ambulatory status in patients with spontaneous intracerebral hemorrhage (ICH).MethodsAll patients with ICH between 1985 and 2011 were prospectively registered in a population-based registry in Dijon, France, and included in the study. Outcomes of ICH survivors were assessed at discharge from their stay in an acute care ward with the use of a 4-grade ambulation scale. Time trends in ambulation disability and place of discharge were analyzed in 3 periods (1985–1993, 1994–2002, and 2003–2011). Multivariable ordinal and logistic regression models were applied.ResultsFive hundred thirty-one patients with ICH were registered, of whom 200 (37.7%) died …
