Kehitysvammaisten aikuisten kestävyyskunnon taso ja muutos ikääntyessä : kahden kävelytestin vertaaminen

2015

Eveliina Keinonen (2015). Kehitysvammaisten aikuisten kestävyyskunnon taso ja muutos ikääntyessä: Kahden kävelytestin vertaaminen. Liikuntakasvatuksen laitos, Jyväskylän yli-opisto, liikuntapedagogiikan pro gradu –tutkielma, 66 s., 3 liitettä. Tutkimuksen tavoitteena oli tarkastella keski-ikäisten kehitysvammaisten naisten ja miesten kestävyyskunnon tasoa vammattomaan väestöön sekä Suomessa yleisesti käytössä oleviin terveysliikunnan suosituksiin verrattuna. Tarkastelun kohteena oli myös kehitysvammaisten kestävyyskunnossa esiintyvät muutokset seitsemän vuoden aikana. Lisäksi tutkimus pyrki selvittämään onko samanaikaisesti suoritettujen UKK-instituutin 2 kilometrin kävelytestin ja Rockport…

Diferencias de opinión sobre el uso de los test: su relación con la edad el género y el sector laboral

2021

Tests are important tools that help psychologists to make decisions about people. In order to propose actions aimed at improving the use of tests, it is important to determine what factors relate to psychologists’ opinions about testing practices. In this study we assess the role of three factors: gender, age, and job sector (public vs. private). In addition, we compare practitioners’ opinions with those reported by professors of test-related subjects (psychometrics, and psychological and psycho- educational assessment). After analyzing a sample of 1,248 members of the Spanish Psychological Association and 95 professors from different universities, results show some differences in opinions …

Prediction model for aneuploidy in early human embryo development revealed by single-cell analysis.

2014

Aneuploidies are prevalent in the human embryo and impair proper development, leading to cell cycle arrest. Recent advances in imaging and molecular and genetic analyses are postulated as promising strategies to unveil the mechanisms involved in aneuploidy generation. Here we combine time-lapse, complete chromosomal assessment and single-cell RT–qPCR to simultaneously obtain information from all cells that compose a human embryo until the approximately eight-cell stage (n=85). Our data indicate that the chromosomal status of aneuploid embryos (n=26), including those that are mosaic (n=3), correlates with significant differences in the duration of the first mitotic phase when compared with e…

Środowisko a antybiotykooporność izolatów Escherichia coli

2017

Pula farmaceutyków w środowisku powiększa się w wyniku kontaminacji wód, gruntów, ścieków, a także surowców pochodzenia zwierzęcego. Obecność antybiotyków w środowisku wpływa nie tylko na zahamowanie rozwoju mikroorganizmów, ale w stężeniu subinhibicyjnym może stymulować ekspresję genów wywołujących zjawisko antybiotykooporności. Celem pracy było porównanie wrażliwości na antybiotyki pałeczek Escherichia coli wyizolowanych z surowego mleka i zmieszanych odpadów drobiarskich. Materiał badawczy stanowiły szczepy E.coli wyizolowane z surowca mleczarskiego i zmieszanych odpadów drobiarskich. Ocenę wrażliwości izolatów na antybiotyki przeprowadzono metodą Kirby-Bauera. Profil oporności E. coli u…

Puhetta arvioinnista : yleisten kielitutkintojen arvioijien käsityksiä arvioinnista

2016

This paper focuses on raters’ beliefs and views of assessment and the factors influencing their judgments and performance as raters in the National Certificates of Language Proficiency (NCLP) Finnish language test. Data were collected using semi-structured interviews (N=18) and content analysis was used to classify the responses. Findings suggest that raters’ experience and training have positive effects on rater performance and the use of assessment criteria. Experienced raters seem to be more familiar with different language proficiency levels and their view of language is more holistic today than during the first years of their rating experience. There are some external factors and lingu…

Towards Automatic Testing of Reference Point Based Interactive Methods

2016

In order to understand strengths and weaknesses of optimization algorithms, it is important to have access to different types of test problems, well defined performance indicators and analysis tools. Such tools are widely available for testing evolutionary multiobjective optimization algorithms. To our knowledge, there do not exist tools for analyzing the performance of interactive multiobjective optimization methods based on the reference point approach to communicating preference information. The main barrier to such tools is the involvement of human decision makers into interactive solution processes, which makes the performance of interactive methods dependent on the performance of huma…

Acceptance test-driven development

2011

Acceptance Test-Driven Development (ATDD) is meant to bring customers, engineers, testers and software developers together and help them understand each other. ATDD is not an automatic testing technique but rather a precise requirement management and software development convention, which helps to avoid misunderstandings between stakeholders and leads to production of program code satisfying only the real requirements making it more simple and clear. Conclusions about benefits and common problems emerging during adoption of ATDD are based on results of a software project which took place while this work was being written. They also concur very well with other case studies. A large framework…

Promoter Activation in Dhfq Mutants as an Efficient Tool for Specialized Metabolite Production Enabling Direct Bioactivity Testing

2019

Abstract Natural products (NPs) from microorganisms have been important sources for discovering new therapeutic and chemical entities. While their corresponding biosynthetic gene clusters (BGCs) can be easily identified by gene‐sequence‐similarity‐based bioinformatics strategies, the actual access to these NPs for structure elucidation and bioactivity testing remains difficult. Deletion of the gene encoding the RNA chaperone, Hfq, results in strains losing the production of most NPs. By exchanging the native promoter of a desired BGC against an inducible promoter in Δhfq mutants, almost exclusive production of the corresponding NP from the targeted BGC in Photorhabdus, Xenorhabdus and Pseud…

The influence of different types of fixed orthodontic appliance on the growth and adherence of microorganisms (in vitro study).

2012

Orthodontic appliances serve as different impact zones and modify microbial adherence and colonization, acting as foreign reserves and possible sources of infection. This study was conducted to investigate the effect of different types of fixed orthodontic appliances on the growth and adherence of microorganisms in oral flora which are Streptococcus mutans (S. mutans) and Candida albicans. Sixty-four of four different fixed orthodontic appliance-samples were used, divided into four groups of sixteen. Type I: Sapphire brackets- Coated wires, type II: Sapphire brackets- Stainless steel wires, type III: Stainless steel brackets- Coated wires and type IV: Stainless steel brackets- Stainless ste…
