Increased impact of technology leads numerous studies to conduct research on the effect of social media on performance. Very limited of such studies have tried to observe and record the use of social media for collaborative learning as a way to improve collaborative authoring. This paper tries to the validation of the technology acceptance model (TAM) on social media use for collaborative learning to enhance collaborative authoring among research students. To achieve the study objective, this paper employed a questionnaire as the main data collection method and distributed it to 1118 responses of various researchers from the Universiti Teknologi Malaysia (UTM) all of whom use social media. The findings were obtained via a quantitative research method, structural equation modeling (SEM-AMOS). The findings from our empirical study indicate that all the hypotheses were supported; we demonstrate that the use of social media positively and significantly related to collaborative authoring through collaborative learning between researchers in higher education. Therefore, the proposed model will help academic and decision-makers formulate the strategies that can encourage students and researchers to use social media to improving collaborative authoring through collaborative learning.

This research study examined the acceptance of the intranet in restaurant franchise systems. The widely accepted Technology Acceptance Model (TAM) developed by Davis (1986, 1989) was the basis for this study. TAM is an excellent model to predict information technology (IT) usage and is based on the Theory of Reasoned Action (TRA). Therefore, TAM was adopted in this study of intranet acceptance. Furthermore, this study attempted to see if the earlier results of TAM are still valid. The original model was modified to include one external variable, franchise support. Data were collected from franchise restaurant systems throughout the United States, excluding Alaska and Hawaii. Of 3,500 questionnaires distributed to individual users of intranet, 161 contained usable responses. The results of regression analysis confirm that TAM is valid for additional applications such as evaluating the intranet in restaurant franchise systems. / Ph. D.

Cloud computing can be used as a way to access services and resources for many organizations; however, hackers have created security concerns for users that incorporate cloud computing in their everyday functions. The purpose of this qualitative multiple case study was to explore strategies used by cloud security managers to implement secure access methods to protect data on the cloud infrastructure. The population for this study was cloud security managers employed by 2 medium size businesses in the Atlanta, Georgia metropolitan area and that have strategies to implement secure access methods to protect data on the cloud infrastructure. The technology acceptance model was used as the conceptual framework for the study. Data were collected from semi-structured interviews of 7 security managers and review of 21 archived documents that reflected security strategies from past security issues that occurred. Data analysis was performed using methodological triangulation and resulted in the identification of three major themes: implementing security policies, implementing strong authentication methods, and implementing strong access control methods. The findings from this research may contribute to positive social by decreasing customers' concerns regarding personal information that is stored on the cloud being compromised.

A survey conducted by the United Nations in 2016 endorses this fact, showing a high rate of technological development with respect to e-government. However, the same publication showed the low rate of citizen participation about it. These results show how, although there are many government technological services, these do not focus on the citizen or in their active participation, but mainly on technological development. In the present study, an adoption model is proposed, extending the Technology Acceptance Model (TAM) incorporating public value, specifically environmental sustainability, as an external variable. The validation of the proposal was made through a validated survey with experts in the environmental field and applied to citizens of the Peruvian capital. Our results show that environmental sustainability is a factor that positively affects the adoption of e-government in Peru and that should be considered by the authorities as an enhancer of citizen participation about it.

Purpose: Low citizen adoption rates jeopardize the success and proliferation of e-government systems. This study aims to understand how the perception of environmental sustainability (ES) can influence a citizen’s intention to use e-government systems. Design/methodology/approach: In a case study in Peru, the technology acceptance model (TAM) adoption model is extended with the construct of ES and evaluated with structural equation modeling. An 18-element, in-person survey was constructed and administered to citizens of Lima, Peru who had prior exposure to e-government systems. Findings: The results show that citizens can be positively influenced to adopt e-government systems if they perceive that doing so will contribute to ES. Research limitations/implications: As this was a preliminary study, further research should focus on specific, as opposed to general, e-government systems, as well as encompassing a broader cross section of the population. Practical implications: Administrators of e-government initiatives can consider public-interest factors, alongside of the common self-interest factors, when looking to improve adoption rates of e-government systems. Originality/value: This is the first time that TAM has been extended with the construct of ES.

Idag är det ett faktum att samhället påverkas av tekniska innovationer, där förändringar på betalningsmarknaden inte är ett undantag. Individer har gått från att betala med kontanter till att allt mer använda sig av tekniska och elektroniska lösningar som betalningsmetod. Dagens digitalisering har medfört en ny möjlig betalningsform, i form av digitala koder, vilket är det som benämns för kryptovalutor. De traditionella kryptovalutorna saknar centraliserat styre, vilket innebär att det ligger utom statens kontroll. Det som har möjliggjort denna typ av valuta är blockkedjetekniken. För att möta denna utmaning har ett flertal länder, där Sverige inte är ett undantag, börjat konstruera en egen digital valuta, vilken går under samlingsnamnet CBDC (Central Bank Digital Currency). Det dessa digitala valutor har gemensamt är att de ännu inte har blivit ett standardiserat betalningsmedel. Tidigare studier har påvisat att individers acceptans är ett utav de största hindren för att implementera nya digitala betalningsmedel. Därav antar denna uppsats en kvantitativ karaktär, med huvudsyfte att undersöka digitala valutors möjlighet som betalningsmedel. Syftet uppfylls genom att mäta vilka faktorer som påverkar individens acceptans till användningen. För detta används en egenkonstruerad analysmodell med hypoteser, som baseras på tidigare forskning om faktorer som påverkar individens betalningsmetod och faktorer som påverkar teknologisk acceptans. Datainsamlingen består av en surveyundersökning där enkät valts som datainsamlingsmetod. Resultatet består av svar från 102 stycken respondenter. Resultatet visar att majoriteten av respondenterna har en positiv acceptans till användningen av digitala valutor som betalningsmedel. Dock är det fortfarande få som har stor erfarenhet av digitala valutor, vilket hänförs till att valutan ännu inte är ett standardiserat betalningsmedel. De faktorer som undersöktes var attityd, erfarenhet, förtroende, vanor, socialt inflytande, reglering och design. Enligt resultatet av korrelationsanalys är det individens attityd, det sociala inflytandet och förtroendet till blockkedjetekniken som visade starkast samband till acceptansen. Resultatet visade även att individer som har högt förtroende till staten har låg acceptans till digitala valutor. Resultatet av regressionsanalys visade att samtliga faktorer har en signifikant, och därmed betydande förklaringskraft till variationen i acceptansen. Slutligen testades analysmodellen med hjälp av strukturell ekvationsmodellering, där samtliga faktorer inkluderades. Slutsatsen av studien blev således att individens attityd, erfarenhet och det sociala inflytandet har en signifikant påverkan på individens acceptans till digitala valutor som betalningsmedel.

Bakgrund: E-handeln har ökat betydligt under de senaste åren på grund av den ökade tekniska utvecklingen. Den största utmaningen som e-handlare står inför är behovet av att ha en effektiv strategi för orderuppfyllelse. För att motverka detta problem övergår vissa företag sin orderuppfyllelse till andra aktörer och använder sig då av alternativ som t.ex. dropshipping. Dropshipping är en affärsmodell där orderuppfyllandet sker genom att leverantören levererar ordern direkt till kunden. I denna rapport undersöks därför hur dropshipping kan användas för att optimera sitt kassaflöde och orderuppfyllelse. Syfte: Syftet med denna studie är att undersöka hur svenska företag skulle kunna optimera sitt kassaflöde och orderuppfyllelse med hjälp av dropshipping.Studien har dessutom undersökt vilka möjligheter och hinder som är förknippade med användningen av dropshipping i en e-handelsmodell. Genom att studera dropshipping i en svensk kontext med avseende på kassaflöde och orderuppfyllelse, kan vi få en förståelse för vilken roll dropshipping spelar jämfört med andra traditionella logistiska orderuppfyllesemetoder inom den svenska e-handeln. Metod: I denna studie har en kvalitativ forskningsmetod använts för att få insikter om dropshipping kan optimera e-handlares kassaflöde och orderuppfyllelse. Forskningsstrategin tog form av en flerfallsstudie där sex olika e-handelsföretag medverkade. Slutsats: Dropshipping har visat sig ha stor betydelse för optimering av orderuppfyllelse. Denna metod påverkar försörjningskedjan genom att ansvaret för orderuppfyllesen överlåts till tredjepartsleverantörer. Genom att utnyttja befintlig infrastruktur och teknik förbättrar dropshipping optimeringen av kassaflödet i slutändan, eftersom antalet aktörer förblir opåverkat och lagerkostnader elimineras.

As the delivery of healthcare has become more sophisticated, scientific, and complex, the need for HIM (Health Information Management) professionals at all levels has increased, and the role and status of those managing these functions has increased accordingly. (AHIMA, September 24, 2007). Studies by the Institute of Medicine and others have found suboptimal technology use throughout the healthcare industry. The American Health Information Management Association (AHIMA) developed the e-HIM Virtual Lab (V-lab) to train students in the use of new technology applications in response to IOM findings. Faculty are the gatekeepers for use of instructional technology in educational settings. Many disciplines have evaluated instructional technology use by students. There are very few studies on faculty use of instructional technology. There are no published studies of the determinant factors influencing health information management (HIM) faculty use of instructional technology. Therefore, the purpose of this study is to evaluate the faculty's attitude and behavior toward the use of the V-lab instructional technology. A non-random one group pretest posttest design was used to test the hypothetical Instructional Perception -Technology Acceptance Model (IP- TAM) for faculty perceptions regarding system functionality, usability and technology acceptance. The Path Analysis determined the strongest construct indicators for intent to use the V-lab were Perceived Usefulness (PU), Perceived Ease Of Use (PEOU), System Functionality and Usability (SFU). These findings support the recommendation for a collaborative examination of the existing V-lab systems to improve utilization and success.

Mental health self-help accounts on social media often provide tips and strategies for individuals struggling with mental health difficulties to improve mental health outcomes. As mental health poses a public health concern that causes economic and physical problems worldwide, this self-help approach offers a potential solution to help millions of people at risk. In accordance with Technology Acceptance Models, how useful an individual finds a social media account should predict their intent to follow such accounts. Additionally, since social media accounts are highly visual content-driven, aesthetics may be a significant driver of intent to follow social media accounts. The present research examines how feelings of depression moderate the relationship between perceived usefulness of a self-help account and intent to follow the self-help account, as well as perceived aesthetics and intent to follow the self-help account. An online study was conducted with N = 410 participants in which participants were shown both self-help accounts and non-self-help accounts from Instagram. Participants were then asked to rate each account's perceived visual appeal and usefulness and their intent to follow these accounts. Lastly, participants completed a Center for Epidemiological Studies Depression Scale (CES-D) and a Temporal Experience of Pleasure Scale (TEPS). Results indicate that while aesthetics and perceived usefulness of self-help social media accounts are positively correlated with intent to follow such accounts, perceived usefulness is the dominating predictor of intent to follow.
