In this thesis, we leverage Edgar Schein’s (1992) organizational culture framework alongside multimodal discourse analysis to identify textual and visual cues that reveal CEOs’ organizational culture mindsets. We analyze 72 LinkedIn posts from Swedish unicorn startup CEOs in 2022-2023 to explore whether the scholarly assumptions about organizational culture mindsets of successful startup leaders will be reflected in our analysis. Our findings indicate that our developed novel analytical framework effectively identifies how CEOs’ LinkedIn communication reveals their innovation, growth-oriented, visionary, equality, hierarchical and appreciation mindsets. We also discover inconsistencies between text and image communication in our data. By making the process of how CEOs implement various textual and visual tools to construct their posts explicit, we help CEOs and their stakeholders gain a better understanding of the effects of these choices and the implicit meanings that are created in this process. Finally, we open the door for further research on organizational culture mindsets that are revealed through CEO communication, contributing a new dimension to research on CEO communication on social media.

Framväxten av sociala mediers etablering i samhället har bidragit till att individers dagliga användning har ökat. Det har resulterat i att användarbeteenden har förändrats och att sociala medieplattformar numera kan användas för att främja karriären. En plattform som används för att framställa en professionell identitet inför andra är den sociala nätverksplattformen LinkedIn. Dock har det framkommit att det är svårare för universitetsstudenter att framställa en professionell identitet på plattformen, vilket påverkar möjligheten att bli upptäckt av rekryterare. Studien har därför ämnat att undersöka och skildra mötet i förstadiet av en rekryteringsprocess mellan universitetsstudenter och rekryterare på LinkedIn. Syftet har varit att rama in det förväntade rollagerandet på plattformen och besvara frågeställningen: “Vilka faktorer ligger till grund för universitetsstudenters professionella identitetsskapande i mötet med rekryterare på LinkedIn?”. Studien har av den anledningen tillämpat en kvalitativ forskningsstrategi och utfört sju semistrukturerade intervjuer, varav fyra med universitetsstudenter samt tre med rekryterare. Dessutom har ett teoretiskt ramverk för identitetsskapande tillämpats med syftet att undersöka de faktorer som ligger till grund för universitetsstudenternas professionella identitetsskapande i mötet med rekryterare på LinkedIn. I studiens resultat kunde fyra faktorer identifieras och skildras. Faktorerna är: konstruktion av framställning på front-stage, osäkerhet i framställningen, den idealiserade framställningen samt den sociala normen. Det råder olika uppfattningar mellan rekryterare och universitetsstudenters gällande den professionella framställningen som förväntas av universitetsstudenter och som berör ideal, sociala normer, stigman och okända observatörer på LinkedIn. / The emergence and establishment of social media in society have increased individuals' daily use. As a result, user behaviors have changed, and social media platforms allow individuals to advance their careers. One platform used to present a professional identity is the social networking platform LinkedIn. However, it has appeared to be more difficult for university students to present a professional identity on the platform, which affects the possibility of being discovered by recruiters. Therefore, the study aims to investigate and describe the meeting between university students and recruiters on LinkedIn in the pre-stage of a recruitment process. The purpose has been to frame the expected role-playing on the platform and answer the question: "What factors underlie university students' professional identity creation in the meeting with recruiters on LinkedIn?". For this reason, the study has applied a qualitative research strategy and conducted seven semi-structured interviews, four with university students and three with recruiters. In addition, the study applied a theoretical framework for identity creation. The purpose was to examine the factors that form the foundation of university students' professional identity creation in the meeting with recruiters on LinkedIn. The study identified and described four factors. The factors are the creation of front-stage presentation, uncertainty in the presentation, the idealized presentation, and the social norm. In addition, there are various perceptions between university students and recruiters of the professional presentation expected of university students, which affects the ideals, social norms, stigma, and the unknown audience on LinkedIn.

The overall security posture of information systems (IS) depends on the behaviors of the IS users. Several studies have shown that users are the greatest vulnerability to IS security. The proliferation of smartphones is introducing an entirely new set of risks, threats, and vulnerabilities. Smartphone devices amplify this data exposure problem by enabling instantaneous transmission and storage of personally identifiable information (PII) by smartphone users, which is becoming a major security risk. Moreover, companies are also capitalizing on the availability and powerful computing capabilities of these smartphone devices and developing a bring-your-own-device (BYOD) program, which makes companies susceptible to divulgence of organizational proprietary information and sensitive customer information. In addition to users being the greatest risk to IS security, several studies have shown that many people do not implement even the most basic security countermeasures on their smartphones. The lack of security countermeasures implementation, risky user behavior, and the amount of sensitive information stored and transmitted on smartphones is becoming an ever-increasing problem. A literature review revealed a significant gap in literature pertaining to smartphone security. This study identified six socio-cognitive factors from the domain of traditional computer security which have shown to have an impact on user security behaviors and practices. The six factors this study identified and analyzed are mobile information security self-efficacy, institutional trust, party trust, and awareness of smartphone risks, threats, and vulnerabilities and their influence on smartphone security practices and behaviors. The analysis done in this research was confirmatory factor analysis (CFA) – structural equation modeling (SEM). The goal of this study was to cross-validate previously validated factors within the context of traditional computer security and assess their applicability in the context of smartphone security. Additionally, this study assessed the influential significance of these factors on the security behaviors and practices of smartphone users. This study used a Web-based survey and was distributed to approximately 539 users through Facebook® and LinkedIn® social media outlets which resulted in 275 responses for a 51% response rate. After pre-analysis data screening was completed, there were a total of 19 responses that had to be eliminated due to unengaged responses and outliers leaving 256 responses left to analyze. The results of the analysis found that vulnerability awareness, threat awareness, and risk awareness are interrelated to one another which all in turn had significance in predicting self-efficacy, security practices, and behaviors. This intricate relationship revealed in this study indicates that a user has to have an increased awareness in all three categories of awareness before they can fully understand how to protect themselves. Having an increased awareness in one category does not impact the overall security posture of the user and that risk, threat, and vulnerability awareness all work together. Another interesting find was that as risk awareness increased the less the smartphone users protected themselves. This finding warrants additional research to investigate why the user is more averse to risk, and willing to accept the risk, despite their increased awareness. Finally, institutional trust and party trust was found not to have any significance on any of the factors. These findings should give smartphone users and organizations insight into specific areas to focus on in minimizing inappropriate security behaviors and practices of smartphone users. More specifically, users and organizations need to focus on educating users on all three factors of threats, risks, and vulnerabilities in order for there to have any impact on increasing self-efficacy and reducing inappropriate security behaviors and practices.

No. of bitstreams: 1 JOSÉ GILDO DE ARAÚJO JÚNIOR - DISSERTAÇÃO PPGCC 2016..pdf: 44985365 bytes, checksum: 7cf3e353444964c334025b7c6f4f6df5 (MD5) Previous issue date: 2016-12-13 / CNPq / Há algum tempo pesquisadores e analistas de mercado vêm apresentando indícios da previsibilidade de mercados acionários. Embora acredite-se que o mercado de ações seja imprevisível, análises de previsibilidade realizadas em bolsas da China, Turquia, Hong Kong, Itália, Teerã e EUA vêm mostrando o contrário. O fato é que a hipótese de eficiência de mercado foi planteada em 1970, e não se poderia prever as mudanças culturais e tecnológicas que impactaram o mundo, como o aumento da capacidade de processamento dos computadores, o desenvolvimento de técnicas de aprendizagem de máquina, a publicação de notícias online e a exposição em tempo real da opinião de investidores em redes sociais, por exemplo. A combinação destes elementos passaram a potencializar o lucro de investidores à medida que simplificaram o monitoramento e a gestão do risco, a compreensão do cenário econômico e até a realização de análises complexas sobre setores, índices e ações em poucos minutos. Este trabalho se propôs a lançar luz sobre relações e impactos que as notícias econômicas publicadas em jornais brasileiros, online, mantêm com o mercado acionário nacional em dois níveis de análise: índice Bovespa e setores. Inicialmente, foram coletadas notícias econômicas publicadas em jornais de alta circulação no Brasil entre 2000 e 2015, seus comentários e suas repercussões nas redes sociais Twitter, Facebook, Linkedln e GooglePlus. A análise de correlação entre o índice Bovespa e a quantidade de compartilhamento de notícias em redes sociais revelam uma correlação negativa de 48%. Além disso, por meio da análise de sentimento das notícias coletadas, verificou-se que a quantidade de notícias positivas publicadas é, em média, 4.5 vezes superior ao de negativas, e que, apesar disso, as notícias negativas são mais repercutidas nas redes sociais que as positivas. Para os setores, verificou-se que o setor mais previsível apenas por meio de notícias econômicas é o setor de Petróleo, Gás e Biocombustíveis enquanto o menos previsível é o setor Bens Industriais. Por fim, as variáveis extraídas das notícias foram utilizadas como base no desenvolvimento de modelos de predição tanto para o índice Bovespa quanto para os setores da BM&FBOVESPA. De forma geral, os resultados encontrados superaram estatisticamente baselines comumente utilizados em ~ 20%. / For some time researchers and market analysts have shown evidence of predictability of stock markets. Although many investors believe that the stock market is unpredictable, predictability analysis in China, Turkey, Hong Kong, Italy, Tehran and the US stock markets has shown the opposite situation. The Efficient-Market Hypothesis (EMH) was designed in 1970 and could not anticipate the cultural and technological changes that affected the world, such as the increased processing power of computers, the development of machine learning techniques, real time publication of news and opinions of investors in social media platforms, such as twitter and facebook, for example. The combination of these elements enabled investors to perform more complex analysis of sectors, índices and stocks in almost real time, thus increasing their understanding of the stock market dynamics and improving their likelihood of success. his study aimed to shed light on the relationships and impacts that economic news published in online Brazilian newspapers, have with the national stock market in two leveis of analysis: Bovespa Index and sectors. Initially, we collected economic news published in high-circulation newspapers in Brazil between 2000 and 2015, their comments and their repercussions on social medias like Twitter, Facebook, Linkedln and GooglePlus. The correlation analysis between the Bovespa index and the amount of news shared on social networks showed a negative correlation of 48%. Furthermore, using sentrment analysis it was found that the amount of positive news reported is in average of 4.5 times higher than the negative, and, nonetheless, the negative news are more rebound on the social media than positive news. For the sectors, it was found that the most predictable sector by economic news is the Oil, Gas and Biofuels while the less predictable is the Industrial Goods sector. Finally, the variables drawn from the news were used as as input for the definition of prediction models for both the Bovespa Index and for the sectors of BM& FBOVESPA. In general, the results overperformed baselines such as the random classifier in ~ 20%.

La tesi approfondisce alcune delle risorse strategiche che permettono la sopravvivenza e il miglioramento delle organizzazioni. Essa si divide in tre articoli, il fil rouge è l’utilizzo degli esperimenti come metodologia di ricerca. Riconoscendo la creatività dei lavoratori come una competenza strategica e una misura di performance sia a livello individuale che di gruppo, il primo articolo confronta gli effetti di tre stili di leadership – trasformazionale, transazionale e laissez-faire – sulla creatività individuale e mostra quale di essi sia più appropriato per il suo incremento. I mood positivi e negativi sono stati inclusi nel modello di ricerca come mediatori e la motivazione intrinseca è stata inclusa come moderatore. Il secondo articolo estende il primo e indaga le medesime relazioni a livello di team. Non solo i leader, ma anche i follower sono rilevanti per le organizzazioni: i talenti sono la linfa vitale delle organizzazioni e il loro comportamento deve essere indagato in modo da attrarli, trattenerli e gestirli. Il terzo articolo indaga quindi il comportamento dei talenti nella ricerca di una posizione lavorativa e nella scelta del datore di lavoro tramite l’utilizzo di social media e l’analisi delle pagine sui social network. / The purpose of the thesis is to provide an in-depth understanding of some strategic resources that allow organizational survival and improvement. The thesis is divided into three papers and the fil rouge is the use of experimental design as research methodology. Recognizing creativity as a strategic competence and a measure of individual or team performance, the first paper compares the effect of three leadership styles – transformational, transactional and laissez-faire – on individual creativity, thus showing which leadership behavior is the most suitable for enhancing it. Positive and negative moods are included in the research design as mediators and individual intrinsic motivation is included as moderator. The second paper is an extension of the first one and investigates the same relationships at a team level of analysis. Furthermore, not only leaders are relevant for the organizations, but followers too. Talents are the life-bloods of organizations and their behaviours have to be detected for attracting them, but also for retaining and managing them. The third paper untangles the job seekers’ behaviors in looking for a job and choosing a company rather than another one basing their choice on the screening of social media and social network pages.

The thesis is focused on describing the procedures through which organizations can acquire and retain high-quality long-term workers in the ICT sector. Most of the described procedures can be easily transfered to other industries. Brand new approaches that can be applied in the process of recruitment, are discussed as well, specifically, the possibility of using online social networks such as Facebook, LinkedIn or Twitter. Outsourcing is another, fairly new option of acquiring employees. An example of such a service is oDesk. The following part of the work describes the processes that are used in recruitment and retaining the skilled employees in the Unicorn company, which is the major producer of software in the Czech Republic. Despite Unicorn`s long-term achievements and experience in implementing the various human resources management and other related activities in order to acquire and maintain high-quality employees, the author was able to formulate specific proposals and recommendations that may contribute to their further improvement and streamlining. These recommendations are subject to the final part of the thesis.

Social media and its underlying technologies have created an advanced and sophisticated platform for digital activism. As a result, companies and organizations are undergoing a pivotal transition in how they reach and engage with users in a fast and efficient manner. Specifically, nonprofit organizations have taken advantage of using social media platforms to not only amplify their brand and image, but also spread awareness of their mission to larger audiences. The aim of this study is to delve into the use of social media in the activism measures of nonprofit organizations and determine its effectiveness across the organizations. First, an in depth literature analysis will explore social media and its impact on digital activism as well as how social media has been utilized by renown nonprofits in the case studies of Greta Thunberg, and the Black Lives Matter movement. Second, the study will depict both qualitative and quantitative data taken from local nonprofit organizations that explore the impact of social media towards their activism measures. The case companies used in this study are Dolgin Digital Media and the Local Initiatives Support Corporation. After a thorough analysis of the qualitative and quantitative data, it was determined that social media is an effective tool for nonprofits to not only communicate their mission efficiently and quickly to a mass audience, but also as a mechanism for brand amplification. / Sociala medier och dess underliggande tekniker har skapat en avancerad och sofistikerad plattform för digital aktivism. Som ett resultat genomgår företag och organisationer en avgörande övergång i hur de når och samarbetar med användare på ett snabbt och effektivt sätt. Specifikt har ideella organisationer utnyttjat att använda sociala medieplattformar för att inte bara förstärka sitt varumärke och sin image, utan också sprida medvetenheten om deras uppdrag till större publik. Syftet med denna studie är att fördjupa användningen av sociala medier i ideella organisationers aktivismåtgärder och bestämmadess effektivitet i organisationerna. Först, en djupgående litteraturanalys kommer att utforska sociala medier och dess inverkan på digital aktivism samt hur sociala medier har använts av kända ideella organisationer i fallstudierna av Greta Thunberg, och Black Lives Matter-rörelsen. För det andra kommer studien att skildra både kvalitativa och kvantitativa data som tas från lokala ideella organisationer som undersöker effekterna av sociala medier på deras aktivismåtgärder. De fallföretag som används i denna studie är Dolgin Digital Media och Local Initiatives Support Corporation. Efter en grundlig analys av kvalitativa och kvantitativa data, det fastställdes att sociala medier är ett effektivt verktyg för ideella organisationer för att inte bara kommunicera sitt uppdrag effektivt och snabbt till en masspublik, utan också som en mekanism för varumärkesförstärkning.
