Targets of Online Hate: Examining Determinants of Victimization Among Young Finnish Facebook Users.

Drawing from routine activity theory (RAT), this article seeks to determine the crucial factors contributing to youth victimization through online hate. Although numerous studies have supported RAT in an online context, research focusing on users of particular forms of social media is lacking. Using a sample of 15- to 18-year-old Finnish Facebook users (n = 723), we examine whether the risk of online hate victimization is more likely when youth themselves produced online hate material, visited online sites containing potentially harmful content, and deliberately sought out online hate material. In addition, we examine whether the risk of victimization is higher if respondents are worried about online victimization and had been personally victimized offline. The discussion highlights the accumulation of online and offline victimization, the ambiguity of the roles of victims and perpetrators, and the artificiality of the division between the online and offline environments among young people.

Does Social Belonging to Primary Groups Protect Young People From the Effects of Pro-Suicide Sites?

BACKGROUND: The Internet has facilitated the existence of extreme and pathological communities that share information about ways to complete suicide or to deliberately harm or hurt oneself. This material is user-generated and easily accessible. AIMS: The present study analyzed the buffering effect of social belonging to a primary group in the situation of pro-suicide site exposure. METHOD: Cross-national data were collected from the US, UK, Germany, and Finland in spring 2013 and 2014 from respondents aged 15-30 years (N = 3,567). Data were analyzed by using linear regression separately for women and men for each country. RESULTS: A higher level of belonging to a primary group buffered the negative association of pro-suicide site exposure with mental health, measured as happiness, although the results were not consistent in the subgroups. US male subjects showed a significant buffering effect of the sense of belonging to family while the belonging to friends had a buffering effect among four other subgroups: British female and male subjects and Finnish female and male subjects. CONCLUSION: The results underline the positive potential of primary groups to shield young people's mental health in the situation of pro-suicide site exposure.

Pro-Anorexia and Anti-Pro-Anorexia Videos on YouTube: Sentiment Analysis of User Responses.

BACKGROUND: Pro-anorexia communities exist online and encourage harmful weight loss and weight control practices, often through emotional content that enforces social ties within these communities. User-generated responses to videos that directly oppose pro-anorexia communities have not yet been researched in depth. OBJECTIVE: The aim was to study emotional reactions to pro-anorexia and anti-pro-anorexia online content on YouTube using sentiment analysis. METHODS: Using the 50 most popular YouTube pro-anorexia and anti-pro-anorexia user channels as a starting point, we gathered data on users, their videos, and their commentators. A total of 395 anorexia videos and 12,161 comments were analyzed using positive and negative sentiments and ratings submitted by the viewers of the videos. The emotional information was automatically extracted with an automatic sentiment detection tool whose reliability was tested with human coders. Ordinary least squares regression models were used to estimate the strength of sentiments. The models controlled for the number of video views and comments, number of months the video had been on YouTube, duration of the video, uploader's activity as a video commentator, and uploader's physical location by country. RESULTS: The 395 videos had more than 6 million views and comments by almost 8000 users. Anti-pro-anorexia video comments expressed more positive sentiments on a scale of 1 to 5 (adjusted prediction [AP] 2.15, 95% CI 2.11-2.19) than did those of pro-anorexia videos (AP 2.02, 95% CI 1.98-2.06). Anti-pro-anorexia videos also received more likes (AP 181.02, 95% CI 155.19-206.85) than pro-anorexia videos (AP 31.22, 95% CI 31.22-37.81). Negative sentiments and video dislikes were equally distributed in responses to both pro-anorexia and anti-pro-anorexia videos. CONCLUSIONS: Despite pro-anorexia content being widespread on YouTube, videos promoting help for anorexia and opposing the pro-anorexia community were more popular, gaining more positive feedback and comments than pro-anorexia videos. Thus, the anti-pro-anorexia content provided a user-generated counterforce against pro-anorexia content on YouTube. Professionals working with young people should be aware of the social media dynamics and versatility of user-generated eating disorder content online.

Internet and everyday life: the perceived implications of internet use on memory and ability to concentrate.

The growing role of Internet in all aspects of everyday life has led to speculations over the impacts beyond the traditional questions of access or sociability. This in mind, the main focus in this article was to examine how Finns, for majority of whom Internet use has become commonplace activity, perceive the impacts of Internet use since first adopting the technology. In this study, we examine how Internet user history and perceived computer skills, along with different sociodemographic factors, appear to reflect on the perceived impacts of Internet adoption in terms of memory and ability to concentrate. According to the results, almost one in five of the respondents reported changes concerning their memory or ability to concentrate, with skilled computer users and nonworkers, in particular, perceiving the change. Factors such as age-related differences and exposure to potential information overload at work were identified to explain the perceived change. Our data were collected in a survey-gathering information on the everyday life and well-being of Finns. The sample consisted of 2000 Finnish speakers aged 15 to 64 years. The response rate was 46 percent (N=908).

ICT activity in later life: Internet use and leisure activities amongst senior citizens in Finland.

The article examines the relationship between the Internet use and leisure activities amongst Finnish seniors. Traditionally, the young have been the most active users of the Internet and other information and communication technologies (ICTs). In recent years, however, older age groups have increasingly become more interested in ICT, yet a significant proportion of Finnish seniors rarely log on. Using data from a nationally representative survey (N = 542) conducted in the summer of 2010, we explored the connection between the frequent Internet use and general leisure activity. The basic socio-demographic variables were controlled in the analysis. The findings indicate that the active Internet use in old age has a strong positive correlation with the number of different leisure activities amongst Finnish seniors. As most European societies continue to age, it is clear that future research should focus on the implications and the role the Internet and other new ICTs will play in the everyday life amongst the ageing citizens.

Digestibility and energy value of cereal-based diets in relation to digesta viscosity and retention time in turkeys and chickens at different ages estimated with different markers.

Digesta viscosity, ileal transit time of digesta, apparent ileal protein digestibility and apparent metabolisable energy (AME(N)) of diets based on wheat and dehulled barley (WB), oats (O) or a mixture of these (WBO) fed as such or with enzyme supplementation in three- and six-week old turkeys and broilers were investigated. In addition, differences between ileal digestibility and AME(N) calculated by using titanium dioxide (TiO2), chromic oxide (Cr2O3) or acid insoluble ash (AIA) as indigestible markers were compared. Digesta viscosities were generally moderate reaching from 2.5 mPa x s to 7.3 mPa x s. The highest viscosities were observed in WBO diets. Viscosities were reduced with age in broilers, and were generally higher in turkeys than in broilers, especially at six weeks of age. Digesta retention time in ileum was elongated with age of the birds, pronouncedly in broilers. Oat inclusion to the diets decreased retention time especially in broilers at six weeks of age. Apparent ileal digestibility of protein ranged from 0.64-0.83, was lower at six weeks of age than at three weeks of age and generally lowest in O diets, especially in turkeys. AME(N) of the diets ranged from 11.2-13.4 MJ/kg being higher at six weeks of age than at three weeks of age. AME(N) of Diets O was the lowest but AME(N) of WBO diets was higher than that of WB diets indicating a synergistic interaction of cereals, this trend being more pronounced in broilers. Enzyme supplementation decreased viscosity and improved AME(N) in most diets, but did not affect ileal protein digestibility. Differences between ileal digestibility estimates obtained with TiO2 or Cr2O3 were small and mainly not significantly different from 0. AME(N) estimates were generally higher when calculated with Cr2O3 than with TiO2. AIA gave remarkably lower AME(N) values than TiO2 (the significant differences ranging from 0.24-0.94 MJ/kg). In addition, effects of markers on AME(N) estimates interacted with age of the birds and dietary treatments.

Effect of age of growing turkeys on digesta viscosity and nutrient digestibility of maize, wheat, barley and oats fed as such or with enzyme supplementation.

The effects of age of growing turkeys and beta-glucanase-xylanase activity-containing feed enzyme supplementation on digestibility and feeding value of pelleted maize, wheat, barley and oats were investigated in growing turkeys using excreta collection and ileal sampling by slaughter. Excreta were collected and turkeys were slaughtered at 4, 8 and 12 weeks of age. Viscosity of jejuno-duodenal digesta, caecal volatile fatty acid concentration, ileal crude protein digestibility, total tract fat digestibility and AMEN were assayed using titanium dioxide as an indigestible marker. The highest viscosities were observed in barley and wheat. Viscosity of wheat, barley and oats digesta decreased while caecal volatile fatty acid concentration, fat digestibility and AMEN increased with age. Ileal crude protein digestibility was highest in wheat and lowest in barley. Ileal crude protein digestibility significantly declined with age in most feeding treatments. Enzyme reduced digesta viscosity most efficiently in wheat and barley and improved ileal crude protein digestibility, total tract fat digestibility and AMEN in wheat, barley and oats, but interactions occurred, the effect of enzyme on viscosity being the most remarkable for wheat and barley and for the young birds.

Effect of age of growing turkeys on nutrient digestibility and energy value of cereal-soybean-based diets.

Ileal and total tract digestibility of protein, total tract digestibility of fat and AMEN of cereal-based diets were assayed in growing turkeys at four, seven and 12 weeks of age. Fat digestibility and AMEN improved linearly with age. Total tract protein digestibility improved with age according to a curvilinear trend, while ileal protein digestibility improved from 4-7 weeks of age but decreased from 7-12 weeks of age. It can be concluded that higher AMEN values could be applied when formulating diets for older than for younger turkeys. Regarding protein digestibility more investigation is needed but a possible fall in values after the first weeks of age may be expected.
