Collaborative crowdsourcing has evolved over recent years as a problem-solving model that builds on interactions that take place within crowds or self-organizing teams that form and dissolve in response to an open call. Unlike microtasking, its effectiveness depends primarily on collective actions rather than individual efforts, particularly for no...

Interest in artificial intelligence (AI)-driven crowd work has increased during the last few years as a line of inquiry that expands upon prior research on microtasking to represent a means of scaling up complex tasks through AI mediation. Despite the increasing attention to the macrotask phenomenon in crowdsourcing, there is a need to understand t...

Amid pandemic lockdowns, digital nomads exhibit remarkable resilience and adaptability, showcasing the evolving dynamics of remote work. As Artificial Intelligence (AI) intersects with digital nomadism, it offers profound insights into the future of work, transcending national borders and reshaping traditional workplace norms. Lever-aging the Gioia...

The advent of digital technology has contributed to experiencing liquid lifestyles and flexible work arrangements with different mobility routes and targets. Escaping the exhausting routine of commuting to and from work has been a key driver of digital nomadism, a phenomenon that has become increasingly widespread across the globe and is often cent...

Since 2016, the demand for remote work has grown by nearly 400%, with 3.5 million remote job vacancies posted, and it is expected to continue to grow in the coming years. Therefore, one of the challenges in advancing remote work is fostering innovation, particularly serendipity, in a remote workforce. This fortunate discovery can pave the way for...

In the dynamic intersection of business and technology, teams of specialists must collaborate to solve complex problems and drive important projects. However, there's a space for improvement in our understanding of cross-domain collaboration within IT projects. This research addresses this gap by analyzing collaborative knowledge work practices, em...

Artificial Intelligence (AI) applications streamline workflows, automate tasks, and require adaptive strategies for effective integration into business processes. This research explores the transformative influence of AI on various industries, such as software engineering, automation, education, accounting, mining, legal services, and media. We inv...

The rise of artificial intelligence agents and information technology platforms governed by data-driven algorithms has had profound impacts on the way knowledge work is managed and carried out. Concerning the novel uses of digital work platforms, the arising tensions might suggest that the socio-technical design frameworks adopted by major tech fir...

In this paper, we continue our investigations on digital nomadism and the impact of COVID-19 pandemic on the work-related aspects and lifestyle of digital nomads (DN). The findings presented in this empirical study reflect the analysis of the impact of COVID-19 outbreak (and its waves) on the market economy and work-life boundaries of DNs as percei...

The massification of remote work, in response to the COVID-19 pandemic, has been causing significant changes in productive and working arrangements, both for individuals, organizations, and society. At the level of personal life philosophy, for example, this transformation can be evidenced in the dissemination of digital nomadism values such as wor...

With the widespread availability and pervasiveness of artificial intelligence (AI) in many application areas across the globe, the role of crowdsourcing has seen an upsurge in terms of importance for scaling up data-driven algorithms in rapid cycles through a relatively low-cost distributed workforce or even on a volunteer basis. However, there is...

Recent technological advancements have made Large Language Models (LLMs) easily accessible through apps such as ChatGPT, Claude.ai, Google Bard, and HuggingChat, allowing text generation on diverse topics with a simple prompt. Considering this scenario, we propose three machine-machine collaboration models to streamline and accelerate Delphi execut...

Stakeholders' Map of Digital Nomad Ecosystem published in "The role of wannabes in the digital nomad ecosystem in times of COVID-19 pandemic" October 2022

The purpose of this paper is to reveal a set of new results obtained from an ongoing investigation focused on the way that the particular characteristics which are inherent to "wannabe" digital nomads' activities contribute to the sustainability of the whole digital nomad ecosystem. In line with the premise of this research, we assume the importanc...

In this paper, we report on new findings about the results of an empirical study which aims to investigate how the COVID-19 pandemic has been shaping nomadic work practices and also challenging the lifestyles of digital nomads (DN). To do this, we collected textual data from posts in a Reddit community. We argue that, in order to understand how to...

We report the first findings of an empirical study aimed at investigating how COVID-19 pandemic has impacted the work practices and lifestyles of digital nomads (DN). To do this, we analyzed messages, questions and comments posted by digital nomads in a specific online discussion community of the Reddit social network. Preliminary findings indicate...

Over the past decade, online crowdsourcing has established itself as an emerging paradigm that industry and government have been using to harness the cognitive abilities of a multitude of users distributed around the world. In this context, microtask crowdsourcing has become the method of choice for addressing a wide range of diverse problems. Micr...

The data exponential growth in last decade, creates a new challenge for Data Mining Algorithms. The aim of this dissertation is analysing the impact of this phenomenon on current methodologies and present emerging approaches for solving this problem.

Brazilian Digital TV (SBTVD) is an pioneering initiative . The Standard presents an middleware layer (Ginga) that provides advanced interactivity features. It layer has been specified at time of dissertation publication. These interactive layer opens up a promising research field for security and software development. This dissertation about issues...
