Abraham Bids Farewell to Hagar and Ishmael: Continuity and Variation of the Iconographic Type
2021
In traditional Christian artistic visualization, the episode of Hagar and Ishmael in the desert has given rise to various iconographic types: “The feast for the weaning of Isaac and Sara’s protests,” “Abraham bids farewell to Hagar and Ishmael,” “Hagar and Ishmael in the desert” and “Divine salvation for Hagar and Ishmael”. This study looks into the continuity and variation over time of the second of these types: “Abraham bids farewell to Hagar and Ishmael,” the one most depicted out of this entire biblical topic or episode. Since the Byzantine Octateuch in the East (11th century.) and the Canterbury Hexateuch (ca. 1025&ndash…
Castron kastraatio : Pedro Juan Gutiérrezin proosa castrokommunistisen utopian romuttajana
2016
This dissertation explores how Pedro Juan Gutiérrez's fiction corresponds to the Castrocommunist utopia. The study has three goals: (1) to explain how Castro-communism has formed, altered and impacted on Cuban literature; (2) to investigate how Gutiérrez's fiction corresponds to the Castro-communist utopia and ideals; and (3) how his parodic (anti)detective story Nuestro GG en La Habana (2004) is based on and relates to Cuban socialist detective stories, Graham Greene's spy farce Our Man in Havana, Castro-communist historiography and the social, ideological and economic shifts in Cuban society during the 1990s. Previous studies on Gutiérrez's fiction have focused almost exclusively on the a…
Escapism and Excessive Online Behaviors: A Three-Wave Longitudinal Study in Finland during the COVID-19 Pandemic.
2022
Excessive online behaviors refer to harmful or disproportionate use of digital network applications. Such behaviors are likely to be associated with escapist motives. Our aim was to analyze whether escapism predicts excessive gambling, excessive gaming, and excessive internet use over time. A longitudinal sample of Finnish residents aged 18–75 years (n = 1022, 51.27% male) was surveyed at three time points during the COVID-19 pandemic in 6-month intervals: April 2021 (Time 1), October–November 2021 (Time 2), and April–May 2022 (Time 3). Of the original Time 1 respondents, 66.80% took part in the surveys at both Time 2 and Time 3. All surveys included measures for excessive gambling (Problem…
The Mediating Role of Psychological Distress in Excessive Gambling among Young People: A Four-Country Study
2021
Background and aims: Loneliness and a low sense of mastery are associated with excessive gambling, but the underlying processes of these relationships remain unstudied. Because psychological distress can increase vulnerability to excessive gambling, we investigated its mediating role in these relationships among young people. To meet the need for cross-country research, we also observed how these relationships occur in four countries with different cultures. Design, setting, and participants: Demographically balanced cross-sectional survey data were collected from 15–25-year-olds in Finland (n = 1200
Social Ecological Model of Problem Gambling : A Cross-National Survey Study of Young People in the United States, South Korea, Spain, and Finland
2021
Problem gambling among young people is an emerging trend globally. The online environment in particular offers various possibilities for gambling engagement. This is the first cross-national survey study using the social ecological model to analyze problem gambling, especially in the online context. The study aimed to analyze how different social ecological spheres explain problem gambling. Participants were young people aged 15–25 in the United States (n = 1212), South Korea (n = 1192), Spain (n = 1212), and Finland (n = 1200). The South Oaks Gambling Screen (SOGS) instrument measured problem gambling. The regression models analyzed problem gambling with measures of intrapersonal, interper…
Vibrio Proteases for Biomedical Applications: Modulating the Proteolytic Secretome of V. alginolyticus and V. parahaemolyticus for Improved Enzymes P…
2019
Proteolytic enzymes are of great interest for biotechnological purposes, and their large-scale production, as well as the discovery of strains producing new molecules, is a relevant issue. Collagenases are employed for biomedical and pharmaceutical purposes. The high specificity of collagenase-based preparations toward the substrate strongly relies on the enzyme purity. However, the overall activity may depend on the cooperation with other proteases, the presence of which may be essential for the overall enzymatic activity, but potentially harmful for cells and tissues. Vibrios produce some of the most promising bacterial proteases (including collagenases), and their exo-proteome includes s…
Comprehensive analysis of a Vibrio parahaemolyticus strain extracellular serine protease VpSP37
2015
Proteases play an important role in the field of tissue dissociation combined with regenerative medicine. During the years new sources of proteolytic enzymes have been studied including proteases from different marine organisms both eukaryotic and prokaryotic. Herein we have purified a secreted component of an isolate of Vibrio parahaemolyticus, with electrophoretic mobilities corresponding to 36 kDa, belonging to the serine proteases family. Sequencing of the N-terminus enabled the in silico identification of the whole primary structure consisting of 345 amino acid residues with a calculated molecular mass of 37.4 KDa. The purified enzyme, named VpSP37, contains a Serine protease domain be…
First Record of the Nematode Physaloptera squamatae in the Helminth Community of the Introduced Anole Anolis grahami (Polychrotidae) on Bermuda
2021
The gastrointestinal helminth communities of five populations of Anolis grahami, an introduced anole on Bermuda, were surveyed to determine the prevalence, abundance, and species diversity of parasites in these reptiles. Only three nematode species were found, Atractis scelopori, Parapharyngodon cubensis, and Physaloptera squamatae. This species, P. squamatae, is recorded for the first time in Anolis grahami on Bermuda, probably introduced through its arthropod intermediate host. The role of the host A. grahami as a “spillover” agent for these parasites is discussed.
Pohjois-Amerikka rahastot : case-tutkimus rahastojen suoriutumisesta
2016
Tässä tutkielmassa tutkitaan Yhdysvaltoihin sijoittavien rahastojen suoriutumista aika- välillä 01/2005-01/2016. Aineisto koostuu rahastoista, joita joko hallinnoidaan Yhdys- valloissa tai Pohjoismaissa, ja joiden sijoitukset kohdistuvat Yhdysvaltoihin. Aineisto koostuu 10:n pohjoismaalaisen rahaston ja 16:n amerikkalaisen rahaston kuukausi- tuotoista ja rahastot ovat kasvurahastoja. Tässä työssä asetetaan vastakkain amerikkalaisten salkunhoitajien ja pohjoismaalaisten salkunhoitajien osaaminen. Rahastojen suoriutumista on mitattu Jensenin (1968) alphalla ja kolmen faktorin mallilla (Fama & French, 1993). Rahastojen suoriutuminen on mitattu koko aikavälillä, mutta lisäksi myös kahdella lyhy…
Pokeri-ilta : etnografinen tutkimus rahapelaamisen yhteisöllisyydestä
2017
Tutkielmani tavoitteena on tutkia mitä merkityksiä opiskelijoiden pokeriyhteisö antaa yhteisölle ja pokeripelille: miksi he pelaavat pokeria ja minkä takia he viettävät aikaa yhteisössä? Peliyhteisön tutkimuksen pohjana käytän sosiologi Michel Maffesolin käsitettä uusheimolaisuus, johon sovellan ja vertaan tutkimaani yhteisöä. Lisäksi käyn läpi yhteisön jäsenten suhtautumista rahapelaamiseen ja erityisesti Texas Hold’em pokerivariaatioon, jota he yhteisössä pelasivat. Tutkimusmetodeina käytän teemahaastattelua sekä passiivista havainnointia ja osallistuvaa havainnointia. Tutkielmaani varten haastattelin viittä yhteisön jäsentä. Passiivista havainnointia yhteisössä toteutin kuukauden ajan ja…
