<p class="p1">Much can be at stake depending on the choice of words used to describe citizen science, because terminology impacts how knowledge is developed. Citizen science a quickly evolving field that mobilizing people's involvement in information development, social action and justice, large-scale gathering. Currently, wide variety terms expressions are being refer concept 'citizen science' its practitioners. Here, we explore these help provide guidance for future growth this field. We...
Human computation is a computing approach that draws upon human cognitive abilities to solve computational tasks for which there are so far no satisfactory fully automated solutions even when using the most advanced technologies available. citizen science projects consists in designing systems allow large crowds of volunteers contribute scientific research by executing tasks. Examples successful Galaxy Zoo and FoldIt. A key feature this kind project its capacity engage volunteers. An...
Human computation is a computing approach that lets humans perform tasks for which there's still no satisfactory solution, even when today's most sophisticated infrastructures are used. One stream of human âvolunteer thinking,â' systems gather volunteers willing to contribute by executing in citizen-science systems. The authors report the findings volunteer engagement characterization study two astronomy projects: Galaxy Zoo and Milky Way Project. Approximately 10 million executed 100,000...

A human computation system can be viewed as a distributed in which the processors are humans, called workers. Such systems harness cognitive power of group workers connected to Internet execute relatively simple tasks, whose solutions, once grouped, solve problem that equipped with only machines could not satisfactorily. Examples such Amazon Mechanical Turk and Zooniverse platform. application comprises each them performed by one worker. Tasks might have dependencies among other. In this...
Opportunistic grids are distributed computing infrastructures that harvest the idle cycles of resources geographically distributed. In these grids, demand for is typically bursty. During bursts resource demand, many grid required, but on other times they remain long periods. If kept powered even when neither processing their owners workload nor jobs, exploitation not efficient in terms energy consumption. One way to reduce consumed idleness periods place computers form a "sleeping" mode...
Citizen science projects engage people in activities that are part of a scientific research effort. On multi-project citizen platforms, scientists can create consisting tasks. Volunteers, turn, participate executing the project's Such type platforms seeks to connect volunteers and scientists' projects, adding value both. However, little is known about volunteer's cross-project engagement patterns benefits such for volunteers. This work proposes Goal, Question, Metric (GQM) approach analyse...
This work presents an approach for using GitHub classroom as a shared, structured, and persistent repository to support project-based courses at the Software Engineering Undergraduate program PUC Minas, in Brazil. We discuss needs of different stakeholders that guided development approach. Results on perceptions professors students show brings benefits. Besides lessons learned, we present insights improving education next generation software engineers by employing metrics monitor skill...
This work explores the user experience with two situated visualizations that lie on different points of design space. The first visualization - Activity Clock displays aggregate presence laboratory members into a wall clock. second Personal Activities represents same persons individually, in conventional poster media. We interviewed 17 participants and leverage theoretical lens Continuous Engagement Sense-Making to study how decisions impact respect (1) which factors attract users, (2)...
Internet of Things (IoT) systems have aroused enthusiasm and concerns. Enthusiasm comes from their utilities in people daily life, concerns may be associated with privacy issues. By using two IoT as case-studies, we examine users' beliefs, attitudes. We focus on four major dimensions: the collection personal data, inference new information, exchange information to third parties, risk-utility trade-off posed by features system. Altogether, 113 Brazilian individuals answered a survey about...
Abstract Citizen-government communication is essential in preparedness and adaptation to climate events. Local-level government authorities have sought communicate via social media, but little known about their strategies citizens’ participation replying publications. This study draws on conceptual frameworks for Social Media Presence Human Engagement establish behavioural modelling topic approaches assessing citizen-authority from a long-term perspective. Empirical analyses focus official...
Understanding user behavior in generated-contend systems (UGCs) is a fundamental building block for maximizing usefulness of these systems. For example, the importance users' connections and degree iteration needed order to build meaningful recommendation In this paper, we evaluate impact network on marking photos as favorites Flickr considering various levels distance between users topology. We have observed that first-degree contacts are clearly biggest contributors evaluation hers/his...
In this paper, we propose a task redundancy strategy based on measures of accuracy volunteers. Simulation results show that our reduces the number generated replicas compared to pessimistic and moderate strategies. It also generates similar or less optimistic strategy.

Abstract BitTorrent currently contributes a significant amount of inter-ISP traffic. This has motivated research and development to explore caching locality-aware neighbor selection mechanisms for costly traffic reduction. Recent researches have analyzed the possible effects provided preliminary results on its cacheability. However, little is known about specifics design that affect cache effectiveness operation, such as replacement policy size. study addresses this gap with comprehensive...
This paper proposes a new policy for dynamic frequency scaling: productivity-aware scaling (PAFS). PAFS aims at optimizing energy consumptions while still satisfying performance requirements of given application. In contrast to the commonly-used on demand scaling, may keep processor in power save state even high CPU-usage situations. will be case as long application (or set applications) which productivity is preserved presents acceptable (e.g., stablished by QoS contract). Our experiments...
Interactive systems are increasingly present in people’s daily lives, generating new demands for interface and interaction. Examples of those derived from human values, such as: gender identity, privacy, the need to provide explanations people who use them. Therefore, be successful, professionals working area HumanComputer Interaction (HCI) sensitive these values. Unfortunately, there still few pedagogical resources help HCI students develop sensitivity. Seeking contribute solution this...
Support cards summarise a set of core information about subject. The periodic table chemical elements and the mathematical tables are well-known examples support for didactic purposes. Technology professionals also use recalling such as syntactic details programming languages or harmonic colour palettes designing user interfaces. While have proved useful in many contexts, little is known its Human-Computer Interaction (HCI) field. To fill this gap, study proposes evaluates process creating...
Depending on the way they are designed, interactive systems may inadvertently influence opinions, choices and actions of their users. To avoid this problem, there has been a growing demand for type system to be able explain users how outputs generated. This is called "right an explanation", or explainability requirement. User perceptions still little addressed in context, example: (1) do people value software explainability? (2) what typical user profiles terms work seeks elucidate users'...
