Disability, Health-Related Quality of Life and Mortality in Lumbar Spine Fusion Patients : A 5-Year Follow-Up and Comparison With a Population Sample
2022
Study Design: Prospective follow-up study. Objectives: We aimed to assess the effect of lumbar spine fusion (LSF) on disability, health-related quality of life and mortality in a 5-year follow-up, and to compare these results with the general population. Methods: 523 consecutive LSF operations were included in a prospective follow-up. Disability was assessed by the Oswestry Disability Index (ODI), and HRQoL by the 36-item Short Form (SF-36) questionnaire using the physical and mental summary scores (PCS and MCS). The patients were compared with an age-, sex-, and residential area matched general population cohort. Results: The preoperative ODI in the patients was 46 (SD 16), and the change …
Combining Sequence Analysis and Hidden Markov Models in the Analysis of Complex Life Sequence Data
2018
Life course data often consists of multiple parallel sequences, one for each life domain of interest. Multichannel sequence analysis has been used for computing pairwise dissimilarities and finding clusters in this type of multichannel (or multidimensional) sequence data. Describing and visualizing such data is, however, often challenging. We propose an approach for compressing, interpreting, and visualizing the information within multichannel sequences by finding (1) groups of similar trajectories and (2) similar phases within trajectories belonging to the same group. For these tasks we combine multichannel sequence analysis and hidden Markov modelling. We illustrate this approach with an …
The ALHAMBRA survey: B -band luminosity function of quiescent and star-forming galaxies at 0.2 ≤ z < 1 by PDF analysis
2016
[Aims]: Our goal is to study the evolution of the B-band luminosity function (LF) since z ∼ 1 using ALHAMBRA data. [Methods]: We used the photometric redshift and the I-band selection magnitude probability distribution functions (PDFs) of those ALHAMBRA galaxies with I ≤ 24 mag to compute the posterior LF. We statistically studied quiescent and star-forming galaxies using the template information encoded in the PDFs. The LF covariance matrix in redshift - magnitude - galaxy type space was computed, including the cosmic variance. That was estimated from the intrinsic dispersion of the LF measurements in the 48 ALHAMBRA sub-fields. The uncertainty due to the photometric redshift prior is also…
Learning to read with Graphogame, an ethnography in a Peruvian rural school
2015
The purpose of the present ethnographic case study is to examine what happens when the literacy learning software Graphogame, designed in Finland, is introduced in a new and radically different context, that of a poor rural school in the Peruvian Andes. The research attempts to complement the quantitative approach which has dominated the research on Graphogame. It also aims to take into consideration the unique circumstances and challenges of rural Peru and how they can affect the use and implementation of the software. I spent two months in the rural school of Quilcas, where nine struggling readers used Graphogame for daily 20 minutes remedial sessions. In this research setting, I conducte…

Do opposite ends of same factors underlie life satisfaction vs. depressive symptoms among older people?
2021
Abstract Background Although depressive symptoms are more common among older than younger age groups, life satisfaction tends to remain stable over the life course, possibly because the underlying factors or processes differ. Aim To study whether the factors that increase the likelihood of high life satisfaction also decrease the likelihood of depressive symptoms among older people. Methods The data were a population-based probability sample drawn from community-dwelling people aged 75, 80, and 85 years (n = 1021). Participants’ life satisfaction was measured with the Satisfaction with Life Scale and depressive symptoms with the Centre for Epidemiologic Studies Depression Scale (CES-D). Phy…
Attitudes towards people with mental disorders in a general population in Finland :
2011
Stigma is common toward persons with mental health problems and can be defined as a label that sets a person apart from others, links her or him with undesirable characteristics and leads to avoidance by others in society. To aid in the planning of effective and well-targeted initiatives to reduce stigma I examined in my dissertation the prevalence of stigmatizing attitudes of a general population and the factors associated with stigmatizing of people with mental disorders in western Finland. Further, because only a minority of persons with depression are actually treated for their disorder it was also highly interesting to identify the role stigma might have on the use of mental health ser…
Depression and Violence in Adolescence and Young Adults: Findings From Three Longitudinal Cohorts
2017
Objective Despite recent research demonstrating associations between violence and depression in adults, links in adolescents are uncertain. This study aims to assess the longitudinal associations between young people’s depression and later violent outcomes. Method We used data from three cohorts with different measurements of depression exposures and subsequent violent outcomes. In a Dutch community cohort Research on Adolescent Development And Relationships (RADAR; N = 623) and a population-based British birth cohort Avon Longitudinal Study of Parents and Children (ALSPAC; N = 4,030), we examined the longitudinal links between adolescent depressive symptoms and violent behaviors from age 1…
MATERIAL DEPRIVATION AMONG FOREIGNERS IN ITALY
2014
In all European countries, migrant populations tend to have worse living conditions than native; this is particularly true for those born outside the EU. This paper proposes a new way to look at the relative living conditions of foreigners by looking at non-monetary (or ‘direct’) indicators of material deprivation in Italy-a country characterized by the presence of a wide range of nationalities. To examine differences in economic integration of foreigners, the paper documents deprivation differentials across groups of foreigners. In particular, we measure differences in material deprivation between groups of foreigners once we control for the demographic and socioeconomic characteristics of…
Modeling Political Corruption in Spain
2021
Political corruption is a universal phenomenon. Even though it is a cross-country reality, its level of intensity and the manner of its effect vary worldwide. In Spain, the demonstrated political corruption cases that have been echoed by the media in recent years for their economic, judicial and social significance are merely the tip of the iceberg as regards a problem hidden by many interested parties, plus the shortage of the means to fight against it. This study models and quantifies the population at risk of committing political corruption in Spain by identifying and quantifying the drivers that explain political corruption. Having quantified the problem, the model allows changes to be …
