As power systems become more reliant on intermittent resources, system operators are faced with the fact that the availability of intermittent resources is beyond human control and largely unpredictable. Due to the lack of compliance from intermittent resources to follow strict dispatch instructions, the dispatch instruction for an intermittent resource is proposed to be a desired dispatch range or...
In this paper, we consider the unit commitment problem of a power system with high penetration of renewable energy. The optimal day-ahead scheduling of the system is formulated as a risk-averse stochastic optimization model in which the load balance of the system is satisfied with a high prescribed probability level. In order to handle the ambiguous joint probability distribution of the renewable...
This mini-track is one of the key international platforms at which the transformational aspects of e-Government, as well as their implications for government and society, are being discussed from a multidisciplinary perspective.
Despite decades of heavy investments in information technology (IT) and information systems (IS) in government systems and considerable amounts of research on how IS contributes to organizational performance and success, IS investments are still considered risky business. Fewer than 50% of IS projects deliver the expected functionality on time and on budget. As the world becomes increasingly more...
Despite the global success enjoyed by a few social media platforms such as Wikipedia and Facebook, many platforms that target geographically bounded communities struggle to sustain users' participation over time. Understanding what makes such "hyper-local" communities sustainable can lead to better technologies for encouraging community awareness and civic participation. However, little...
The term smart city is a fuzzy concept, not well defined in theoretical researches nor in empirical projects. Several definitions, different from each other, have been proposed. However, all agree on the fact that a Smart City is an urban space that tends to improve the daily life (work, school,) of its citizens (broadly defined). This is an improvement from different points of view: social, political,...
Executive agencies are not the only entities generating websites and using other information technologies. The judicial branch is also making progress toward developing better portals to improve their processes and strengthen the relationships with citizens and other stakeholders. In fact, most judicial agencies have created their own websites with different levels of technological sophistication...
Open data in administration is a phenomenon in which public sector information is made available and can be used by everybody for what it seems an unlimited amount of purposes. As publicly available information can often be generated and provided in huge amounts and through multiple sources, specific needs for processing, curation, linking, visualization and maintenance result in the need for Big...
We report on our initial efforts to make sense of e-petitions as policy suggestions by using the NLP technique of "topic modeling" to identify the "topics" that emerge in e-petitions. Using a sample of petitions submitted to the Obama Administration's WtP petitioning system as a case study, we produced 30 emergent topics. 21 out of the 30 topics were initially coded as high-quality...
Access to information and communication technologies (ICTs) is becoming a necessity not only for communication, but for commerce, and for obtaining information about healthcare, employment, and education. Unfortunately, the global digital divide has deepened to include limits on access to mobile broadband services. This paper uses an information ethics (IE) perspective, based the work of Floridi,...
The Social Networking & Communities minitrack focuses on questions of community building and management as mediated by social media and networking platforms. By 'communities', we include communities of practice, epistemic communities, communities of inquiry, as well as fully virtual communities, and social media use that supports or complements geographically based community. We called for...
Social media provides access to diverse and potentially conflicting information about organizations to potential job candidates. However, little is known about the impact of conflicting information between social media and corporate websites for recruitment and attraction. Using an experimental design, we exposed participants to a fictitious company website promoting an employer brand of diversity...
In the contemporary society, gender equality in accessing the job market is advocated, and often protected by law in developed countries. In reality, however, gender differences exist in different aspects and stages of recruitment processes and career development, say from career planning, job search, application, recruitment and promotion. Such differences are usually exemplified by different interesting...
Social media has created the opportunity for organizations to reach a larger audience via the internet. Zoos are interested in using social media to engage people beyond or in lieu of a zoo visit with one of the primary goals being conservation education. This paper describes a novel fifteen-month experiment where zoo animals participated in the Brookfield Zoo Twitter feed. Over 3200 tweets about...
Social media has become part of everyday lives. Discussions about whether social media is relevant to organizations no longer exist, instead, discussions on how to successfully adopt social media prevail. With much uncertainty on what it takes to reach excellence in social media use, companies often start with an uncoordinated approach, not taking into account all potential threats. However, little...
Enterprises that approach uncertainty and risk in software development based on lean and agile methods [1] often do experience financial planning of projects as a restriction. Traditional budgeting and cost reporting is a system based on rigid frames, and it -- along with the process of project cost accounting -- burdens the lean and agile enterprise with unnecessary and counterproductive overhead...
We conduct a qualitative, interview-based study with 12 participants in order to shed further light on the success factors of agile ISD because quantitative studies reported on contradictory results. First, we identify four success factors from previous literature that form the conceptual basis of our investigation. Those factors are the team, customer, organization, and communication. We extend previous...
Key performance indicators are used by some large enterprises to alert executives to opportunities and dangers. Executives seek "leading indicators" to help them make decision early enough to make a difference. In large enterprises adopting agile practices, managers sometimes use behavioral compliance metrics to help teams self-assess or to gauge how practices are performed. These often...
In agile Model-Driven Engineering, the evolution of diverse software artifacts is omnipresent. Especially the evolution of metamodels, defining the grammar of, e.g., Domain Specific Languages, is quite challenging, since many dependent artifacts, including models and transformations, have to be co-evolved to re-establish consistency. Although much research effort has been spent to automate co-evolution,...
