The motivational landscape of first-person shooter games

Abstract. The purpose of this research was to gain better understanding of the motivations to play video games, particularly first-person shooter games. The aim was therefore to produce a motivational landscape that describes and categorizes the main motivations to play first-person shooter games (FPS). The study tries to expand the understanding of motivations to play. Therefore, qualitative research method was chosen for gaining a better understanding. The chosen research strategy is case study and the cases used in this study are Battlefield 3 and Counter-Strike: Global Offensive. These two cases represent popular games in FPS-genre. The empirical material was collected by using semi-structured interviews. Total of seven (7) persons were interviewed for this study. All interviewees were Finnish males (ages 22–28) that are experienced gamers. This study expands the motivation research of gaming. From the academic standpoint, the study offers an empirically grounded categorization for analyzing the motivations to play FPS-games: achievement, learning, social interaction, entertainment and escapism. The study gives structure to a complex and elusive subject of motivation, deepens the understanding of the content of the categories and reveals the underlying processes behind it. In addition, the study makes a division between intrinsic and extrinsic motivations. From managerial standpoint, the study offers comprehensive and balanced structure for evaluating games in terms of their motivational appeal and may therefore help in game development. Game developers should understand that the game needs to provide enough intrinsic motivation to keep players interested. Extrinsic motivation should be used as something that enhances the gameplay experience without destroying it. In-depth understanding of the player’s motivations to play is a vital part of every game company’s business decision-making practices. Video game companies should consider motivations to play when they design monetization models for their games. From a societal standpoint, the parents of gamers could benefit from this study by understanding more of what is actually happening when their children play FPS-games

Yield, Quality and Nitrogen Use of Forage Maize under Different Nitrogen Application Rates in Two Boreal Locations

Research focusing on the nitrogen (N) application and N use of forage maize (Zea mays L.) in the boreal region is either limited or non-existent. The aim of this study was to investigate the response of yield, quality and N recovery efficiency (NRE) of forage maize to an increase in the N application rate and different climatic conditions in two locations in Finland. The field experiment was conducted in southern (Helsinki; 60° N) and central (Maaninka; 63° N) Finland in 2019 and 2020. Dry matter (DM) yield, forage quality and NRE were determined for N application rates of 100, 150 and 200 N kg ha−1. The DM yield was similar to all studied N application rates. Moreover, there were no marked differences in the studied forage quality traits or the NRE following the N application rates. However, the NRE of maize was generally low at 45%. The current study recommends a N application rate of 100–150 N kg ha−1 for forage maize in the boreal region. There is no need to increase the N application from current recommendations since climate conditions seem to limit the growth, development and NRE of forage maize. The observed low NRE of forage maize warrants further research in the future

Inarijärven tilan kehittyminen vuosina 1960–2009

Inarijärvestä on olemassa kohtuullisen hyvin tutkimus- ja seurantatietoa usean vuosikymmenen ajalta, mikä antaa hyvät mahdollisuudet järven tilaa ja sen kehittymistä kuvaavien mittareiden kehittämiseen ja hyödyntämiseen. Työssä pyrittiin löytämään tutkimus- ja seuranta-aineistoon perustuvia mittareita, jotka kuvaavat monipuolisesti Inarijärven tilaa ja käyttöä, etenkin järven yleisiä hydrologisia ja meteorologisia olosuhteita ja niiden kehittymistä (ilmastonmuutos), järveen tulevaa kuormitusta ja veden laatua, virkistyskäyttöä, rantavyöhykkeen eliöyhteisöjen tilaa, kalakantoja ja kalastusta sekä säännöstelykäytäntöä ja säännöstelyn vaikutuksia. Tavoitteena oli kuvata myös eri muuttujien välisiä vuorovaikutuksia. 2000-luvulla toteutetulla Inarijärven vesiluonnon tilan kannalta aikaisempaa paremmalla säännöstelykäytännöllä on parannettu virkistyskäytön olosuhteita kesällä ja osittain vähennetty säännöstelyn aiheuttamia haittoja rantavyöhykkeen eliöstöön. Vesistön tilan ja käytön kannalta eniten myönteisiä muutoksia on tapahtunut kalakannoissa. Punalihaisten petokalojen saaliit, yksikkösaaliit ja saaliskalojen koko ovat suurentuneet 2000-luvulla hyvän muikkukannan ja tuloksellisten istutusten ansiosta. Inarijärven hydrologisissa mittareissa on havaittavissa merkkejä ilmaston lämpenemisestä. Julkaisu tarjoaa kattavan yhteenvedon Inarijärven tilasta ja sen kehittymisestä viime vuosikymmeninä. Raportin tuloksia voidaan hyödyntää mm. säännöstelykäytännön ja kalaston hoidon kehittämisessä sekä matkailussa, opetuksessa ja yleisessä viestinnässä. Tarkastelu tukee myös vesienhoitotyötä, koska se auttaa ymmärtämään biologisten laatutekijöiden tilaan vaikuttavia tekijöitä ja selittämään syitä järven ekologisen tilan kehityssuunnille. Työssä kehitettyä lähestymistapaa ja mittareita voidaan soveltuvin osin hyödyntää myös muissa vesistöissä

Statins for children with familial hypercholesterolemia

BACKGROUND: Familial hypercholesterolemia is one of the most common inherited metabolic diseases and is an autosomal dominant disorder meaning heterozygotes, or carriers, are affected. Those who are homozygous have severe disease. The average worldwide prevalence of heterozygous familial hypercholesterolemia is at least 1 in 500, although recent genetic epidemiological data from Denmark and next generation sequencing data suggest the frequency may be closer to 1 in 250. Diagnosis of familial hypercholesterolemia in children is based on elevated total cholesterol and low-density lipoprotein cholesterol levels or DNA-based analysis, or both. Coronary atherosclerosis has been detected in men with heterozygous familial hypercholesterolemia as young as 17 years old and in women with heterozygous familial hypercholesterolemia at 25 years old. Since the clinical complications of atherosclerosis occur prematurely, especially in men, lifelong treatment, started in childhood, is needed to reduce the risk of cardiovascular disease. In children with the disease, diet was the cornerstone of treatment but the addition of lipid-lowering medications has resulted in a significant improvement in treatment. Anion exchange resins, such as cholestyramine and colestipol, were found to be effective, but they are poorly tolerated. Since the 1990s studies carried out on children aged 6 to 17 years with heterozygous familial hypercholesterolemia have demonstrated significant reductions in their serum total and low-density lipoprotein cholesterol levels. While statins seem to be safe and well-tolerated in children, their long-term safety in this age group is not firmly established. This is an update of a previously published version of this Cochane Review. OBJECTIVES: To assess the effectiveness and safety of statins in children with heterozygous familial hypercholesterolemia. SEARCH METHODS: Relevant studies were identified from the Group's Inborn Errors and Metabolism Trials Register and Medline.Date of most recent search: 20 February 2017. SELECTION CRITERIA: Randomized and controlled clinical studies including participants up to 18 years old, comparing a statin to placebo or to diet alone. DATA COLLECTION AND ANALYSIS: Two authors independently assessed studies for inclusion and extracted data. MAIN RESULTS: We found 26 potentially eligible studies, of which we included nine randomized placebo-controlled studies (1177 participants). In general, the intervention and follow-up time was short (median 24 weeks; range from six weeks to two years). Statins reduced the mean low-density lipoprotein cholesterol concentration at all time points (moderate quality evidence). Serum aspartate and alanine aminotransferase, as well as creatinine kinase concentrations, did not differ between treated and placebo groups at any time point (low quality evidence). The risks of myopathy (low quality evidence) and clinical adverse events (moderate quality evidence) were very low and also similar in both groups. In one study simvastatin was shown to improve flow-mediated dilatation of the brachial artery (low quality evidence), and in another study treatment with pravastatin for two years induced a significant regression in carotid intima media thickness (low quality evidence). AUTHORS' CONCLUSIONS: Statin treatment is an effective lipid-lowering therapy in children with familial hypercholesterolemia. No significant safety issues were identified. Statin treatment seems to be safe in the short term, but long-term safety remains unknown. Children treated with statins should be carefully monitored and followed up by their pediatricians and their care transferred to an adult lipidologist once they reach 18 years of age. Large long-term randomized controlled trials are needed to establish the long-term safety issues of statins

What Facilitates Return to Work? Patients Experiences 3 Years After Occupational Rehabilitation

Objective We have limited knowledge about the specific elements in an occupational rehabilitation programme that facilitate the process leading to return to work (RTW) as perceived by the patients. The aim of the study was to explore individual experiences regarding contributing factors to a successful RTW, 3 years after a resident occupational rehabilitation programme. Methods The study is based on interviews of 20 individuals who attended an occupational rehabilitation programme 3 years earlier. Ten informants had returned to work (RTW) and ten were receiving disability pension (DP). Data were analysed by systematic text condensation inspired by Giorgi’s phenomenological analysis. Results The core categories describing a successful RTW process included positive encounters, increased self-understanding and support from the surroundings. While the informants on DP emphasized being seen, heard and taken seriously by the professionals, the RTW group highlighted being challenged to increase self-understanding that promoted new acting in every-day life. Being challenged on self-understanding implied increased awareness of own identity, values and resources. Support from the surroundings included support from peer participants, employer and social welfare system. Conclusion Successful RTW processes seem to comprise positive encounters, opportunities for increased self-understanding and support from significant others. An explicit focus on topics like identity, own values and resources might improve the outcome of the rehabilitation process
