Paperiliitto ja kilpailukyky-yhteiskunta : Paperilitto suomalaisen yhteiskunnan rakennemuutoksen vuosina 1985-2009
2010
Tutkimuksen tehtävänä on selvittää, miten Paperiliitto on toiminut suomalaisen yhteiskunnan rakennemuutoksen vuosina 1985-2009. 1980-luvulla tehtiin poliittisia päätöksiä, jotka avasivat kotimaisia markkinoita ulkomaiselle kilpailulle ja omistukselle. Suomi otti ensiaskeleita kohti globalisaatiota. Metsäteollisuudessa se johti perinteisten vientiyhdistysten hajoamiseen ja toimialan kansainvälistymiseen. Samalla paperiteollisuuden kotimaiset työpaikat ovat vähentyneet lähes puoleen 1970-luvulta tähän päivään mennessä. Teollisuustyöpaikkojen katoamista voidaan kutsua deindustrialisaatioksi. 1980-luvun puolivälissä myös Suomessa parikymmentä vuotta käynnissä ollut hyvinvointivaltion laajenemin…
Alkoholinkäytön aiheuttama liikennekuoleman riski Suomessa
2023
Tässä tutkimuksessa analysoidaan juopumuksen asteen vaikutusta kuolemaan johtavan liikenneonnettomuuden riskiin moderneilla tilastollisilla menetelmillä. Tutkimuksen pääaineistona ovat vuosina 2005–2014 Suomessa tapahtuneet kuolemaan johtaneet moottoriajoneuvo-onnettomuudet, joissa oli mukana henkilöauto aiheuttajana tai muuna osallisena. Pääaineistoa täydennetään ratsiatutkimuksista julkaistuilla tilastoilla. Keskeisiä käytettyjä mittareita ovat riskisuhde sekä vakioitu riskisuhde, josta on poistettu sekoittavien muuttujien vaikutusta. Tutkimuksen ensimmäisenä tavoitteena on selvittää, miten pieni veren alkoholipitoisuus alkaa lisätä liikenneonnettomuuden riskiä, ja toisena tavoitteena on …
Liiketoimintaprosessin kuvaaminen transaktiona eri transaktiomallien avulla
2009
Malinen, Mikko Tietojärjestelmätieteen kandidaatintutkielma / Mikko Malinen Jyväskylä: Jyväskylän yliopisto, 2009, 41 s. Kandidaatintutkielma Yrityksen liiketoimintaprosessia tarkasteltaessa voidaan siinä huomata olevan transaktiolle ominaisia piirteitä. Tässä tutkielmassa liiketoimintaprosessilla tar-koitetaan sitä tehtävien ketjua, joka yrityksen täytyy suorittaa saavuttaakseen tietyn liiketoiminnallisen lopputuloksen. Vastaavasti transaktiolla tarkoitetaan toimintojen ketjua, joka suoritetaan tietyn lopputuloksen saavuttamiseksi esi-merkiksi tietokannassa. Transaktion ACID -ominaisuudet (jakamattomuus, ris-tiriidattomuus, erillisyys ja pysyvyys) nousevat keskeisiksi tekijöiksi käsitteide…
On the carrier of inertia
2018
A change in momentum will inevitably perturb the all-embracing vacuum, whose reaction we understand as inertia. Since the vacuum's physical properties relate to light, we propose that the vacuum embodies photons, but in pairs without net electromagnetic fields. In this physical form the free space houses energy in balance with the energy of matter in the whole Universe. Likewise, we reason that a local gravitational potential is the vacuum in a local balance with energy that is bound to a body. Since a body couples to the same vacuum universally and locally, we understand that inertial and gravitational masses are identical. By the same token, we infer that gravity and electromagnetism shar…
Power and language in a multicultural workplace
2015
Today’s work markets are increasingly shaped by the multilingual reality. The present research offers an intercultural communication perspective on language diversity and power relations at modern work environment. Study investigates how young professionals and their foreign colleagues perceive diversity affecting in their communicative behaviours in culturally heterogeneous workplace. Analysis of data from participants has been conducted through an analysis of open ended self‐report questionnaire in a multinational company where English is used daily as a corporate language. In particular, results of present study indicate that more diverse language skills are attributed to perception of p…
Feasibility and reproducibility of electroencephalography-based corticokinematic coherence
2020
Corticokinematic coherence (CKC) is the phase coupling between limb kinematics and cortical neurophysiological signals, reflecting cortical processing of proprioceptive afference, and it is reproducible when estimated with magnetoencephalography (MEG). However, feasibility and reproducibility of CKC based on electroencephalography (EEG) is still unclear and is the primary object of the present report. Thirteen healthy right-handed volunteers (seven females, 21.7 ± 4.3 yr) participated in two combined MEG/EEG sessions 12.6 ± 1.3 mo apart. Participants' dominant and nondominant index finger was continuously moved at 3 Hz for 4 min separately using a pneumatic-movement actuator. Coherence was …
Jump Height from Inertial Recordings : A Tutorial for a Sports Scientist
2019
Jump performance provides meaningful information both for sporting and clinical needs. Current state-of-the-art in jump performance assessment is laboratory-bound, however, out-of-the-laboratory methods are desirable. Therefore, the purposes of the present investigation were 1) to explore whether utilising a novel analytical approach minimises the bias between inertial recording unit (IMU)-based and jump mat-based jump height estimates, and 2) to provide a thorough tutorial for a sport scientist (see appendix) to facilitate standardisation of jump height estimation. Forty one women, men and boys aged 6 to 77 years-of-age completed three maximal counter movement jumps without arm swing, whic…
A hierarchical cluster analysis to determine whether injured runners exhibit similar kinematic gait patterns
2020
Previous studies have suggested that runners can be subgrouped based on homogeneous gait patterns, however, no previous study has assessed the presence of such subgroups in a population of individuals across a wide variety of injuries. Therefore, the purpose of this study was to assess whether distinct subgroups with homogeneous running patterns can be identified among a large group of injured and healthy runners and whether identified subgroups are associated with specific injury location. Three‐dimensional kinematic data from 291 injured and healthy runners, representing both sexes and a wide range of ages (10‐66 years) was clustered using hierarchical cluster analysis. Cluster analysis r…
Effects of barbell back squat stance width on sagittal and frontal hip and knee kinetics
2018
Different stance widths are commonly utilized when completing the barbell back squat during athletic general preparedness training. Width manipulation is thought to influence sagittal plane stimuli to the hip and knee extensors, the primary extensor musculature in the squat. However, how width manipulation affects frontal plane stimuli is less understood. Knowledge of hip and knee net joint moments (NJM) could improve exercise selection when aiming to improve sport-specific performance and prevent injuries. Fourteen adult amateur rugby athletes were recruited for this study. After a familiarization period, participants performed wide- (WIDE, 1.5× greater trochanter width) and narrow-stance …
The reliability of measuring medial gastrocnemius muscle-tendon unit lengths during gait
2021
Background Ultrasound imaging combined with 3D motion analysis allows for in-vivo assessment of muscle-tendon unit lengths during gait. The clinical relevance of analysing the medial gastrocnemius (MG) and Achilles muscle-tendon junction (MTJ), MG mid-muscle belly fascicles (FAS) and muscle thickness was shown. However, their reliability error estimations over the gait cycle is unknown. Research question What are the intra- and inter-session errors associated with extracting MG belly, thickness, FAS and tendon lengths using ultrasound during gait in healthy participants? Methods 3D gait analysis was carried out in ten healthy adults as they walked on an instrumented treadmill at a comfortab…
