The purpose of this study was to provide a clearer understanding of current Korean American adolescents under the recognition that their stories are barely told in educational research. Based on the literature that has described identity as a core concept in understanding adolescence and literacy practice as a dominant tool for identity construction, this study focused on Korean American adolescents' identity construction through their self-directed Internet literacy practices. Four Korean American adolescents living in a mid-size city in the Southwest participated in this study for several months. Data sources included face-to-face interviews, literacy practice logs, participants' literacy products on the Internet, online chat logs, and emails. Collected data were analyzed based on the constant comparative method. Results showed that these youth are active meaning makers with agency, that they constructed multiple, fluid identities within their sociocultural context, and utilized the Internet to stage these identities strategically. The result of this study implies a successful pedagogy needs to begin with careful consideration of each student's changeability and complexity by removing the labels imposed on them related to their ethnicity, race, gender, class, and so forth. This study also implies that literacy researchers' contribution, as messengers of adolescents' literacy practices outside of school, is critical for the a clearer understanding of adolescents. Finally, this study suggests that Korean American community take more interest in diverse voices among Korean American adolescents in the era of globalization. / text

Die Arbeit befasst sich mit der Internetnutzung von psychiatrischen Patienten. Das Angebot an Therapien für Patienten mit psychiatrischen Erkrankungen steigt seit Jahren. Auch die Menge an Informationen, welche vor allem online zu bekommen sind, wird immer größer. Allerdings gibt es nur wenige Informationen zur Internetnutzung von psychiatrischen Patienten im Vergleich zur Gesamtbevölkerung. Sind psychiatrische Patienten bezüglich Zugang zum Internet und Nutzung von Internetinformationen und -therapien benachteiligt?

Das Internet ist in aller Munde. Als neues Medium bietet es vielfältige Möglichkeiten der Kommunikation und der Informationsbeschaffung. Doch wird wirklich das geboten, was die Nutzer wollen? Wollen private Internet-Nutzer nur Unterhaltung, aber nichts kaufen? Wozu nutzen Geschäftsleute das Internet? Wie weit ist die Kundenorientierung von Internet-Dienstleistungen fortgeschritten? Wie soll die ideale Homepage gestaltet sein? Im Mittelpunkt dieses Projekts stehen damit - im Gegensatz zu vorliegenden Untersuchungen - die Anwendungswünsche privater und geschäftlicher Nutzer.

Employees' social media use and its potential links with work-related outcomes have received significant scholarly attention in recent years. The existing studies, however, demonstrated mixed findings and the impact of social media use on employee outcomes remains inconclusive. The current debate on employees' social media use points to the need for a meta-analysis on this particular issue, as it could help provide a more conclusive summary to resolve the inconsistency across studies. This meta-analysis study reviewed empirical studies published in peer-reviewed journals from 2009 to 2018 with the aim to provide robust conclusions about the relationships between employees' social media use and employee outcomes (i.e., job performance, innovative performance, job satisfaction, work engagement, emotional exhaustion and work-life conflict) and to explore the moderators of these associations. A total of 29 journal articles were examined in this thesis. The results of the random-effects model suggested that social media use, in general, has positive and small effects on job performance, job satisfaction, work engagement, and work-life conflict. Its effect on emotional exhaustion, however, was significant but negligible. In addition, a positive but non-significant association was found between social media use and innovative performance. The sub-group and meta-regression analyses further identified the moderators among the positive associations found. Specifically, purpose of social media use and culture moderated the effects of social media use on both job performance and job satisfaction; job position moderated the association between social media use and job satisfaction. The theoretical and practical implications from the results of this study, the limitations of the present meta-analysis, and directions for future research were discussed.

Pornography use has become widespread and mainstream in American society, with estimates that 60% of men and 35% of women have viewed pornography at some time in the last year. Pornography use has been associated with both positive and negative outcomes depending on the user, and some of these conflicting results may stem from problematic measurement. Using a newly validated measure that assesses frequency, duration, arousal, and deliberate or accidental exposure to seven common types of pornography, we sought to understand if the motivations to view pornography differed depending on biological sex of the user and the type of use he or she engaged in. With an MTurk.com sample of 312 participants, we used a variable selection to explore the most consistent predictors of pornography use. Results found that sexually based motivations were consistent motivations to use pornography for both males and females. Educationally based motivations reliably predicted accidental exposure to pornography, while emotions like sadness and tiredness reliably predicted longer durations of pornography use. These results indicate that motivations to view pornography are similar for males and females, and that sexually based reasons and emotions are primary in an individual's decision to use pornography.

<div> In the first chapter, I document that online feedback loops, such as search engines, drive customers and revenue to prominent firms, contributing to rising industry concentration. To identify prominent firms online, I measure centrality in a network of firm websites covering more than 100,000 public and private firms. Industries with firms that are more central become more concentrated and central firms increase their market share during the sample period. This appears to be due to firms' ability to meet earnings expectations. Central firms become more profitable and peripheral firms earn negative risk-adjusted returns and underperform earnings forecasts. Evidence from the COVID-19 shutdown, which drove economic activity to the Internet, supports these conclusions. Central firms received the vast majority of the influx of web traffic and had significantly higher returns during the shutdown.</div><div> </div><div> In the second chapter, I create a novel definition of peer groups (web-based peers) for over 100,000 public and private firms by extracting clusters from a network of firm websites. The network is built from unique data on overlapping web traffic. Peer firms are therefore more likely to have similar website users, and by extension, provide similar products or services. Web-based peer groups are related to traditional industry classifications, the preferred choice when defining industries for private firms, but outperform them in standard benchmarking tests. To further demonstrate the benefits of web-based peer groups, I examine IPO waves. IPO activity is closely related to peer-firm IPO activity in the past 12 months, controlling for the overall IPO market and waves within traditional industries. IPO followers earn lower post-IPO returns up to three months after going public, consistent with these firms being lower quality and attempting to benefit from the successful IPOs of their peers.</div>

[EN] Digital transformation and the internet are changing the way people relate to others, but also the way individuals to themselves and their wellbeing perception. In this thesis, there have been examined definitions, affections, and considerations relative to digital transformation, internet, or wellbeing to deepen and understand better the concepts that will take part in our analysis. There, it has been analyzed the internet use among European Countries attending data provided by the European Social Survey (2016) on a sample of more than 34.700 respondents from 18 countries and its relationship with WB perception of individuals. First, it has been examined the individual relationship of WB of people involved in the survey. Sociodemographic factors as age, education, gender, or country have also been considered to analyze differences. The same exercise has been done with internet use data. Second, it has been examined the effect of considering both concepts (internet use and WB) together and interaction between them, for providing more extensive information and understanding. Then, personal values have been introduced. Values influence people's lives and determine individuals' attitude, behavior, relationships with others and themselves, and even their WB perception. Thus, attending personal values and considerations individuals report on the survey, different personal profiles have been defined. And both, internet use and WB concepts, first at an individual level, and secondly considering their interaction, have been examined for each different profile. Finally, results and conclusions that demonstrate personal values and different individuals profile influence the Internet use and WB perception are presented for discussion. / [ES] La transformación digital y el uso de internet están cambiando la forma en la que las personas interactúan entre ellas, pero también el modo en el que se relacionan consigo mismo, e incluso su propia percepción del bienestar.En esta tesis, se han examinado las definiciones, afecciones y consideraciones relativas a la transformación digital, internet y/o bienestar para profundizar mejor en los conceptos incluidos en el presente análisis. Además, en base a una muestra de la Encuesta Social Europea (European Social Survey) 2016 en una muestra de más de 34.700 participantes de 18 países, se ha analizado el uso de internet entre países europeos, así como su relación entre la percepción del bienestar de las personas. Así, primero se ha examinado la relación y percepción individual del bienestar de las personas incluidas en la encuesta, analizando factores sociodemográficos tales como edad, educación, género o país para analizar las diferencias entre la muestra poblacional. Dicho ejercicio ha sido replicado en lo que al análisis individual del uso de internet se refiere. En segundo lugar, se ha examinado el efecto de considerar ambos conceptos simultáneamente (uso de internet y bienestar) para analizar la inteacción entre ellos y profundizar en los efectos derivados del mismo. Seguidamente se introducen los valores personales. Los valores influencian la vida de las personas determinando su actitud personal, su comportamiento, la relación con ellos mismos y con los demás, e incluso su propia percepción del bienestar. Así, atendiendo a los valores y consideraciones personales proporcionadas en la encuesta, se han definido distintos perfiles personales, para, seguidamente analizar el impacto de el uso de internet y percepción del bienestar primero a nivel individual para cada perfil, y posteriormente valorar la interacción de la confluencia de ambos y la singularidad de su efecto en cada perfil. Por último, se presentan los resultados y conclusiones identificadas, que demuestran que, los valores personales y los diferentes perfiles personales influencian el uso individual de internet y su percepción del bienestar. / [CA] La transformació digital i l'ús d'Internet estan canviant la forma en què les persones interactuen entre si, però també la forma en què es relacionen amb si mateixos, i fins i tot la seva pròpia percepció del benestar. En aquesta tesi s'han examinat les definicions, condicions i consideracions relatives a la transformació digital, Internet i/o benestar, per tal d'aprofundir en els conceptes que s'inclouen en aquesta anàlisi. Partint d'una mostra de l'Enquesta Social Europea (European Social Survey) 2016 amb més de 34.700 participants de 18 països, s'ha analitzat l'ús d'Internet entre els països europeus, així com la seva relació entre la percepció del benestar de les persones. Així, s'ha examinat per primera vegada la relació individual i la percepció del benestar de les persones incloses en l'enquesta, analitzant factors sociodemogràfics com l'edat, l'educació, el gènere o el país per analitzar les diferències existents. Aquest exercici s'ha replicat amb tot alló relatiu a l'anàlisi individual de l'ús d'Internet. En segon lloc, s¿ha examinat l'efecte de considerar els dos conceptes simultàniament (ús d'Internet i benestar) per analitzar l'acció entre ells i aprofundir en els efectes que se'n deriven. També s¿han introduït els valors personals. Els valors influeixen en la vida de les persones mitjançant la determinació de la seva actitud personal, el comportament, la relació amb ells mateixos i els altres, i fins i tot la seva pròpia percepció del benestar. Així, tenint en compte els valors i les consideracions personals previstes en l'enquesta, s'han definit diferents perfils personals, per després analitzar l'impacte de l'ús d'Internet i la percepció del benestar primer a nivell individual per a cada perfil, i posteriorment valorar la interacció de la confluència d'ambdós i la singularitat del seu efecte en cada perfil. Finalment, es presenten els resultats i conclusions identificats, demostrant que els valors personals i els diferents perfils personals influeixen en l'ús individual d'Internet i en la seva percepció de benestar. / Femenía Mulet, S.

The current generation of college students commonly use the Internet for sexual purposes (Boies, 2002; Boies, Cooper, & Osborne, 2004), including finding sexual partners, searching for sex-related information, and viewing sexually explicit materials (SEM) (Boies, 2002). Yet, some authors have suggested that the use of the Internet for sexual purposes might lead to psychological problems (Cooper et al., 2001). However, it is unclear if the problems that are commonly reported (i.e., Internet dependency, isolation, and psychological distress) are caused by using the Internet for sexual purposes. Hence, it is important to examine how college students use the Internet for sexual purposes cross-culturally to determine how common the practice is, how it relates to maladjustment, and to examine if any culture variables are associated with use. Undergraduate students (n = 320) from a public university in the United States and Peruvian undergraduate students (n = 135) from a public university in Lima, Peru filled out questionnaires addressing their online sexual activities, psychological adjustment, and family communication. Peruvian young adults used the Internet significantly more than U.S. young adults to view SEM, find sexual partners, and search for sex-related information. Men, regardless of nationality, used the Internet to view SEM significantly more than women. Peruvian women used the Internet significantly more to view SEM and find sexual partners than U.S. women. Social support, religiosity, and erotophilia were found to moderate the relations between nationality and OSA. Further, for Peruvians and U.S. young adults, using the Internet for OSA was associated with mild distress, but no serious psychological maladjustment. Implications for college students are discussed.
