Examining the structure of credibility evaluation when sixth graders read online texts
2023
Background Previous research indicates that students lack sufficient online credibility evaluation skills. However, the results are fragmented and difficult to compare as they are based on different types of measures and indicators. Consequently, there is no clear understanding of the structure of credibility evaluation. Objectives The present study sought to establish the structure of credibility evaluation of online texts among 265 sixth graders. Methods Students' credibility evaluation skills were measured with a task in which they read four online texts, two more credible (a popular science text and a newspaper article) and two less credible (a layperson's blog text and a commercial tex…

Asiakaspalvelun raportoinnin kehittäminen : case: Line Carrier
2017
Tämän tutkimuksen tavoitteena oli selvittää, miten asiakaspalvelun raportoinnin avulla voidaan kehittää asiakkaan saaman palvelun laatua. Tutkimus toteutettiin toimeksiantona kommunikaatioratkaisuja tarjoavalle Line Carrier Oy:lle. Tutkimuksessa tarkastellaan asiakaspalvelun raportointia osana yrityksen liiketoimintatiedon hallintaa. Tämän lisäksi tutkimuksessa analysoidaan liiketoimintatiedon hallintaan sekä asiakaspalvelun raportointiin liittyviä käsitteitä sekä arvioidaan niiden vaikutusta palvelun laatuun. Tutkimus toteutettiin kirjallisuuskatsauksena sekä empiirinen osuus tapaustutkimuksena, jossa tiedonkeruumenetelmänä käytettiin kumulatiivisia ryhmähaastatteluita. Ryhmähaastattelut t…
Digitizing data acquisition and time-of-flight pulse processing for ToF-ERDA
2016
A versatile system to capture and analyze signals from multi channel plate (MCP) based time-of-flight detectors and ionization based energy detectors such as silicon diodes and gas ionization chambers (GIC) is introduced. The system is based on commercial digitizers and custom software. It forms a part of a ToF-ERDA spectrometer, which has to be able to detect recoil atoms of many different species and energies. Compared to the currently used analogue electronics the digitizing system provides comparable time-of-flight resolution and improved hydrogen detection efficiency, while allowing the operation of the spectrometer be studied and optimized after the measurement. The hardware, data acq…
A simple timestamping data acquisition system for ToF-ERDA
2015
A new data acquisition system, ToF-DAQ, has been developed for a ToF-ERDA telescope and other ToF-E and ToF-ToF measurement systems. ToF-DAQ combines an analogue electronics front-end to asynchronous time stamped data acquisition by means of a FPGA device. Coincidences are sought solely in software based on the timestamps. Timestamping offers more options for data analysis as coincidence events can be built also in offline analysis. The system utilises a National Instruments R-series FPGA device and a Windows PC as a host computer. Both the FPGA code and the host software were developed using the National Instruments LabVIEW graphical programming environment. Up to eight NIM ADCs can be han…

Etic and emic data production methods in the study of journalistic work practices : A systematic literature review
2023
This methodological paper discusses the application of etic and emic perspectives in producing data sets for the study of journalistic praxis. The concepts refer to the researcher-analyst’s and the practitioner-informant’s viewpoints, respectively, and that being the case, they have inherent weaknesses if used independently. We argue that these shortcomings can be mitigated through an integrated application of the concepts and by seeing the two perspectives as complementary to each other. Combining etic and emic perspectives will allow for a more comprehensive understanding of complex yet routinized real-life behaviour such as journalistic work. Following the appraisal of the etic-emic comb…
