Kerlan-Jobe Orthopaedic Clinic Shoulder and Elbow score kyselylomakkeen adaptaatio ja validointi Suomeen
2021
Kerlan-Jobe Orthopaedic Clinic (KJOC) Shoulder and Elbow score -kyselylomake on Yhdysvalloissa kehitetty yli olan urheilijoiden olka- ja kyynärpään itsearvioidun toimintakyvyn työväline. Yli olan urheilulla tarkoitetaan lajeja, joissa yläraajaan kohdistuu toistuvaa kuormitusta hartiatasossa tai sen yläpuolella. Yläraajan vammat ovat kyseisissä lajeissa yleisiä ja luotettavat terveyden seurannan mittarit ovat merkittävä osa urheilijoiden hyvinvoinnin arviointia. KJOC-kysely sisältää esitieto-osion sekä kymmenen yläraajan toiminta- ja suorituskykyä tiedustelevaa kysymystä. Alkuperäinen englanninkielinen KJOC-kysely on osoittautunut päteväksi, toistettavaksi ja muutosherkäksi mittariksi, mutta…
From research question to dissemination: how to design, analyse and present study results
2018
Today, the term “study” is very frequently used in quite a broad sense: survey, clinical trial, analysis, research and other terms with deeply different meanings are often generally indicated as “studies”. A “study” can be generally defined as a process composed of several actions aimed to verify one or more hypotheses (objectives), with the ultimate goal of sharing the answers (results) with a target audience, in the form of a scientific paper, presentation or poster.
Multispectral analysis of color vision deficiency tests
2011
Color deficiency tests are usually produced by means of polygraphy technologies and help to diagnose the type and severity of the color deficiencies. Due to different factors, as lighting conditions or age of the test, standard characteristics of these tests fail, thus not allowing diagnosing unambiguously the degree of different color deficiency. Multispectral camera was used to acquire the spectral images of the Ishihara and Rabkin pseudoisochromatic plates in the visible spectrum. Spectral data was converted to cone signals, and successive mathematics applied to provide a simple simulation of the test performance. Colorimetric data of the each pixel of the test image can be calculated an…

Toolbox for Distance Estimation and Cluster Validation on Data With Missing Values
2022
Missing data are unavoidable in the real-world application of unsupervised machine learning, and their nonoptimal processing may decrease the quality of data-driven models. Imputation is a common remedy for missing values, but directly estimating expected distances have also emerged. Because treatment of missing values is rarely considered in clustering related tasks and distance metrics have a central role both in clustering and cluster validation, we developed a new toolbox that provides a wide range of algorithms for data preprocessing, distance estimation, clustering, and cluster validation in the presence of missing values. All these are core elements in any comprehensive cluster analy…
Species distributions models may predict accurately future distributions but poorly how distributions change: A critical perspective on model validat…
2023
Aim: Species distribution models (SDMs) are widely used to make predictions on how species distributions may change as a response to climatic change. To assess the reliability of those predictions, they need to be critically validated with respect to what they are used for. While ecologists are typically interested in how and where distributions will change, we argue that SDMs have seldom been evaluated in terms of their capacity to predict such change. Instead, typical retrospective validation methods estimate model's ability to predict to only one static time in future. Here, we apply two validation methods, one that predicts and evaluates a static pattern, while the other measures change…
Perceived Retaliation Against Internal Whistleblowers: Evidence From Public Institutions in Sub-Saharan Africa
2014
The study uses power relations theory to investigate existence of perceived retaliation against internal whistleblowers in Sub-Saharan Africa using evidence from employees in public institutions of Kenya. Focus was on the way perceived retaliation is related to seriousness of wrongdoing, whistleblower psychological power and management support to whistleblowers. The research design was quantitative, exploratory and analytical using cross-sectional data. Respondents were selected using simple random sampling and requested to complete a self-administered questionnaire. Findings were that perceived retaliation against whistleblowers exists and it was positively correlated to position of a wron…

Statin intolerance: new data and further options for treatment
2021
Purpose of review Hypercholesterolemia is a major risk factor for cardiovascular diseases. Administration of statins represents the cornerstone of the prevention and treatment of cardiovascular disease, with demonstrated long-term safety and efficacy. This review aims to revisit statin intolerance mechanisms, as well as to discuss new data and therapeutic options. Recent findings Although statins are well tolerated, myopathy and other adverse effects are a challenging problem, being the main reason for poor adherence to treatment and failure in lowering cardiovascular risk. Statin intolerance is the subject of ongoing research, as these drugs are widely used. There are alternative options o…
