Selostuksesta tulkintoihin : aineistojen esittäminen lukiolaisten historian esseissä
2019
Artikkelissa selvitetään tiedonalakohtaisten tekstitaitojen viitekehyksessä, miten lukiolaisten historian esseissä rekontekstualisoidaan aineistona olevia historiallisia -dokumentteja ja miten dokumentteja selostavat ja niitä tulkitsevat esitykset eroavat toisistaan. Aineistona on 52 lukion kurssikokeen yhteydessä kirjoitettua esseetä, joiden tehtävänanto edellyttää aineistojen hyödyntämistä vastauksen perustelussa. Tutkimuksen teoreettisena ja metodologisena viitekehyksenä ovat systeemis-funktionaalinen kieliteoria ja siihen pohjautuva suhtautumisen teoria. Tutkimuksen analyysiyksikön rajauksessa hyödynnetään projektion käsitettä, ja analyysin kohteeksi on valittu sellaiset projektiot, joi…
Changes in personal work goals in relation to the psychosocial work environment: A two-year follow-up study
2011
Associations between changes in the psychosocial work environment and changes in personal work goals were investigated in a two-wave, two-year longitudinal study. Psychosocial work environment was studied within the context of the Effort–Reward Imbalance model (ERI; Siegrist, 1996). The participants consisted of 423 young Finnish managers. Their most important personal work goals were categorized into seven content categories of competence, progression, well-being, job change, job security, organization, and finance at both measurement times. There were differences, especially in changes in the career opportunities factor of reward, between participants whose goals changed during the study.…
Telomere Length in Circulating Leukocytes is Associated with Lung Function and Disease
2014
Several clinical studies suggest the involvement of premature ageing processes in chronic obstructive pulmonary disease (COPD). Using an epidemiological approach, we studied whether accelerated ageing indicated by telomere length, a marker of biological age, is associated with COPD and asthma, and whether intrinsic age-related processes contribute to the interindividual variability of lung function. Our meta-analysis of 14 studies included 934 COPD cases with 15 846 controls defined according to the Global Lungs Initiative (GLI) criteria (or 1189 COPD cases according to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) criteria), 2834 asthma cases with 28 195 controls, and s…
Mean-field theory for superconductivity in twisted bilayer graphene
2018
Recent experiments show how a bilayer graphene twisted around a certain magic angle becomes superconducting as it is doped into a region with approximate flat bands. We investigate the mean-field $s$-wave superconducting state in such a system and show how the state evolves as the twist angle is tuned, and as a function of the doping level. We argue that part of the experimental findings could well be understood to result from an attractive electron--electron interaction mediated by electron--phonon coupling, but the flat-band nature of the excitation spectrum makes also superconductivity quite unusual. For example, as the flat-band states are highly localized around certain spots in the st…
Canon vs. charisma : "Maoism" as an ideological construction
2006
Mao Zedongin (1893–1976) poliittinen ja ideologinen perintö on tutkimuksellisesti jälleen ajankohtainen, kolmekymmentä vuotta ”suuren ruorimiehen” kuoleman jälkeen. Maoa on kuvattu milloin puhdasoppiseksi marxilaiseksi, milloin kiinalaiseksi patriootiksi. Maoismin tutkimuksessa on usein keskusteltu siitä, missä määrin Mao seurasi perinteisiä marxilaisia oppeja ja missä määrin hän taas sisällytti kiinalaisia elementtejä omaan ideologiseen tulkintaansa. Viime aikoina julkisuuteen tulleet historiantulkinnat sen sijaan pyrkivät osoittamaan, että Mao oli vain tunteeton ja väkivaltaan taipuvainen itsevaltias.Kauppinen esittää väitöstyössään, että Maon ideologisen maailmankatsomuksen kannalta ei o…
Customer relationship management: The evolving role of customer data
2013
Purpose – Customer relationship management (CRM) developed a separate identity as a result of companies utilising customer data in managing customer relationships. In this evolution, CRM became a heavily company-oriented construct: customer data were used instrumentally to serve companies’ purposes. However, as companies increasingly shift attention from selling products to serving customers, traditional CRM activities, such as segmentation and cross-selling, may prove inappropriate owing to their inherent orientation towards selling more products to customers. The perspective on customer data usage needs to better address the strategic goal of serving customers. Consequently, the purpose …
Employee trust repair: A systematic review of 20 years of empirical research and future research directions
2021
Employee trust, and increasingly its absence, is a critical topic for researchers and practitioners interested in social relations in the context of work and organizing. Employee trust repair is particularly important in the current disrupted work environment, due to unpredictable changes such as the Covid-19 pandemic and the uncertainty those bring to our lives. It is not surprising that employee trust is attracting increasing interest among researchers and practitioners alike. In this article, we systematically review and take stock of the research on trust repair conducted in the past two decades to provide comprehensive insights and future research directions for researchers and manager…
An effectual approach to executing dynamic capabilities under unexpected uncertainty
2022
This study investigates how business-to-business (B2B) firms navigate contexts of unexpected uncertainty. Building on the theories of effectuation and dynamic capabilities, the study develops a model that highlights how effectual decision-making logic is manifested in the activities B2B firms employ to sense and seize new opportunities and threats and transform existing business operations. The qualitative data were collected in two phases (before and after the COVID-19 outbreak) and consisted of 24 interviews with 13 B2B firms. The findings demonstrate a strong reliance on managers' effectual decision-making in situations of unexpected uncertainty and provide a set of key activities that h…
B2B influencer marketing : Conceptualization and four managerial strategies
2023
While there is a growing body of research on influencer marketing, it focuses almost exclusively on the consumer marketing context, and offers limited insights for business-to-business (B2B) organizations. To address this gap, the purpose of this study is to explore the use of influencer marketing in B2B markets. We draw empirical insights from 22 interviews with a) 12 senior marketing managers representing influencer marketing users in various B2B industries, ranging from industrial product manufacturers to professional service providers, and b) 10 experts from marketing agencies who advise other B2B firms on how to apply influencer marketing. The study findings identify the key elements o…
Development of gas sensors by microwave transduction with phthalocyanine film
2012
International audience; This work presents a new transduction mode for gas sensing using a passive microwave circuit at room temperature. The design of the sensor includes a microstrip line where is deposited a thin molecular layer of cobalt phthalocyanine (CoPc). The material is sensitive to ammonia and toluene. Submitted to an electromagnetic incident wave in the microwave range, the sensor response is a reflected wave. In the presence of ammonia, the reflected wave is specific to the species concentration. The sensor response is the reflected wave over the incident wave ratio at each frequency traduced by the reflected coefficient. The study deals with the influence of molecular sensitiv…
