Realizing benefits in public IT projects: A multiple case study
IT investments in the public sector are large, and it is essential that they lead to benefits for the organizations themselves and for the wider society. While there is evidence suggesting a positive connection between the existence of benefits management practices and benefits realization, less is known about how to implement such practices effectively. The paper aims to provide insights into when benefits are most likely to be realized, and how benefits management practices and roles should be implemented in order to have a positive effect on the projects’ success in terms of realizing benefits. The authors collected data relating to ten Norwegian public IT projects. For each project, they collected data on benefits management from project documents, by interviewing the project owners and benefits owners, and follow-up surveys. The benefits internal to the organization were those with the highest degree of realization, while the societal benefits were those with the lowest degree. Projects assessed to have more specific, measurable, accountable, and realistically planned benefits were more successful in realizing benefits. Benefits owners were most effective when they were able to attract attention towards the benefits to be realized, had a strong mandate, and had domain expertise.

State of Gender Equality in and by Artificial Intelligence

State of Gender Equality in and by Artificial Intelligence
When talking about sustainability, we usually think that it is only about safeguarding the environment; nothing is further from reality. Of course, the environment is a crucial component of sustainability and our survival, but it is important to recall that the society and the economy play important roles in this regard, and without the interconnection and development of these three perspectives it will not be possible to achieve sustainable progress. The Sustainable Development Goals (SDGs) established by the United Nations (UN) defend this idea and address the main challenges that humanity faces. One of these challenges is gender equality, which is identified in the perspective of social sustainability through SDG 5. Gender equality is a very complex and difficult challenge to address due to the great cultural diversity of our society. Thus, achieving this goal will require laying a solid foundation and working together by combining very different fields of knowledge. In this sense, Artificial Intelligence (AI) is one of the fields that is currently having the greatest impact and relevance for the development of new technologies and for the advancement of numerous areas. This growing evolution of AI demonstrates that its repercussions at the social level must be analyzed and addressed in such a way that AI becomes a positive asset for sustainability and, in this particular case, for gender equality.
For all these reasons, this study aims to analyze the current state of the art and collect the existing knowledge in the fields of AI and gender equality, by conducting a Systematic Mapping Study (SMS). The obtained results and findings have allowed us to identify the most relevant advances in this regard, as well as the gaps and drawbacks that currently exist and on which we must urgently focus to address gender equality both in and by AI. In the same way, these findings demonstrate the limited joint development of both fields, but also indicate an increase in the relevance and the number of proposals that these fields are receiving in recent years.

AI-based Soccer Game Summarization: From Video Highlights to Dynamic Text Summaries
Soccer dominates the global sports market, and viewers’ interest in watching videos of soccer matches is ramping up. Globally, there is a huge and constantly increasing amount of soccer game content being generated, including video footage, audio commentary, text metadata, goal and player statistics, scores, and rankings. As a large percentage of audiences prefer to follow only the major highlights of a game, the creation of multimodal (video/audio/text) summaries is of great interest to broadcasters and fans alike. In this regard, it’s crucial to provide game summaries and highlights of the major game moments. However, creating summaries and annotating events most often necessitates the use of expensive equipment and a significant amount of time-consuming manual labor. Recent advancements in Artificial Intelligence (AI) technology have demonstrated great promise in this context. The purpose of this thesis is to use AI to support an automated pipeline for summarizing soccer matches. With Natural Language Processing (NLP) tools and heuristics, the emphasis is on creating comprehensive game summaries in textual form with variable length constraints, based on raw game multimedia (e.g., video and audio streams) and, where appropriate, easily accessible game meta-data. A longformer model has been fine-tuned to output a game summary for a given textual input of game captions. This work also explores the use of game audio in prioritizing game events from a summarization perspective. In particular, the Root Mean Square (RMS) audio intensity score has been extracted and used to extract the event priority to be included in the summary.

Research Incentives in Academia Leading to Unethical Behavior
A current practice in academia is to reward researchers for achieving outstanding performance. Although intended to boost productivity, such a practice also promotes competitiveness and could lead to unethical behavior. This position paper exposes common misconducts that arise when researchers try to game the system. It calls the research community to take preventive actions to reduce misconduct and treat such a pervasive environment with proper acknowledgment of researchers’ efforts and rewards on quality rather than quantity.

Perceived Challenges in Benefits Management - A Study of Public Sector Information Systems Engineering Projects
The field of benefits management gives guidelines on how to plan and realize benefits throughout the life-cycle of a system. However, realizing benefits from information systems projects has proven to be challenging in practice. In this paper, we investigate specific benefits management challenges as perceived by practitioners involved in information systems engineering projects. We conducted 22 interviews with respondents representing nine public sector projects, where challenges in managing benefits were elicited and identified. We elicited six specific benefits management challenges: A - Identifying and describing benefits, B - Alignment of work with planned benefits, C - Reception and acceptance of the planned benefits, D - Organizational issues, E - Alternative or competing solutions, F - Measuring and evaluating benefits. Overlaying these challenges with current normative models on benefits management, we find that: 1. Normative models on benefits management lack sufficient guidance on operative work on how to create information systems fit for realizing benefits and how to introduce these solutions to ensure benefits realization, and 2. Normative models on benefits management do not explicitly leverage the rapid project learning promoted by modern engineering methods. We conclude that more specific benefits management models should be elaborated, which are integrated into modern information systems engineering practices. This will enable best practices on the continuous adjustments of cost and scope according to evolving knowledge in projects to also be adapted to the management of benefits.

Benefit Considerations in Project Decisions

Benefit Considerations in Project Decisions
Software project success is often characterized in terms of time, cost and scope – despite that delivering benefit is the main purpose of a project. In this paper, we explore 1) to what degree benefit considerations influence major project decisions, 2) to what degree a specific set of benefits management challenge are handled and influence major project decisions and 3) if there is any realization (over time) that benefit considerations should receive greater attention. We investigate influence in projects with four types of problem severity: completed projects with only minor problems, completed projects with major problems, projects that were disrupted but completed, and projects that were terminated before completion. We asked 45 software professionals to what degree time, cost, scope, benefit and benefit/cost, as well as benefits management challenges, influence major roject decisions. Our findings indicate that time, cost and scope have a significantly higher degree of influence on project decisions than benefit and benefit/cost. However, practitioners think that benefit and benefit/cost should have significantly more influence on decisions than cost. The benefits management challenges are found to have less influence in the more severe projects. We argue that giving benefits considerations a stronger voice in project decisions would be in line with the desire of practitioners and the prime objective of delivering benefit to stakeholders. We conclude that it is important to understand how to handle benefits management challenges at different stages of project life and that handling such challenges should be integrated with other prime drivers of project success.

Measurement of software development effort estimation bias: Avoiding biased measures of estimation bias

Measurement of software development effort estimation bias: Avoiding biased measures of estimation bias
In this paper, we propose improvements in how estimation bias, e.g., the tendency towards under-estimating the effort, is measured. The proposed approach emphasizes the need to know what the estimates are meant to represent, i.e., the type of estimate we evaluate and the need for a match between the type of estimate given and the bias measure used. We show that even perfect estimates of the mean effort will not lead to an expectation of zero estimation bias when applying the frequently used bias measure: (actual effort – estimated effort)/actual effort. This measure will instead reward under-estimates of the mean effort. We also provide examples of bias measures that match estimates of the mean and the median effort, and argue that there are, in general, no practical bias measures for estimates of the most likely effort. The paper concludes with implications for the evaluation of bias of software development effort estimates.

Assisting Soccer Game Summarization via Audio Intensity Analysis of Game Highlights

Assisting Soccer Game Summarization via Audio Intensity Analysis of Game Highlights
In association football, the development of multimodal summaries is of great importance to both broadcasters and spectators since a large number of viewers choose to follow just the soccer game highlights. The fundamental drive for the development of summarization systems is the requirement to manage huge amounts of data in different formats. By highlighting the most pertinent facts and limiting or omitting unnecessary aspects, summarization helps avoid "information overload." The properties of the audio signals during a particular event can be used to calculate excitement around that event and filter events based on their importance. A root-mean-square (RMS) analysis of audio events was carried out to analyse the excitement across the events in the SoccerNet dataset. It was clearly seen that important events with excitement have a high and distinguishable RMS audio intensity. It was also observed that the generated noise of the crowd was significantly different across various events and if it happened for the home or away team. The intensity was higher for events related to the home team. Likewise, as the wavelet has the benefit of integrating a wave with a specific period, Morlet wavelet analysis was performed for various event types, and the power of the signal across various wavelet scales was analyzed. A distinct signature across various wavelet scales was observed for different events.

Right Thoughts & Right Action: How to Make Agile Teamwork Effective
In Amplify. Vol. 35. Cutter Consortium, Arlington, MA, USA, 2022.Status: Published
Right Thoughts & Right Action: How to Make Agile Teamwork Effective
The authors offer their own Agile Teamwork Effectiveness Model via five teamwork components (shared leadership, peer feedback, redundancy, adaptability, and team orientation) along with three coordinating mechanisms (shared mental models, mutual trust, and communication). They describe the three main ways their model can be useful. First, colocated teams can better understand how their team works by reflecting on how well they meet each factor in the model and by using behavioral markers to identify ways to improve. Second, it helps distributed teams, multi-teams, and teams doing safety-critical development to evaluate themselves and make improvement. Third, it’s a way for Agile teams not doing software development to better manage themselves, provided they’re doing knowledge-intensive work.
