The sustainable extraction of value from IST requires organizations to make efforts to maintain the use of IST aligned with the organization’s objectives. IT-CMF consists of a comprehensive framework to guide the evolution of an organization’s exploitation of IST in 36 management areas. Based on this framework, several evolutionary paths for the improvement of the IST capability can be derived. The prioritization and selection among the available paths may pose a problem for organizations, especially due to the intricate relationships between the different areas of intervention. In this study, we resort to Graph Theory to conduct a network analysis of IT-CMF, in order to assist organizations choosing the evolutionary path with the greatest potential for improving their use of IST, taking into account their strengths, weaknesses, and priorities.","PeriodicalId":41878,"journal":{"name":"IADIS-International Journal on Computer Science and Information Systems","volume":"7 1","pages":""},"PeriodicalIF":0.2,"publicationDate":"2021-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91165952","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With politics aiming to become ever more inclusive and participative ranging from the local to the global level, new technologies and findings about possibilities of self-determined, collaborative work from the field of e-participation emerge, which can be transferred onto organizational participation. We therefore present a procedure for incorporating e-participation approaches in mission statement creation processes to make place for more collaborative and open processes. This paper presents an eight-step nominal group process for the participative online creation of a mission statement. The process was tested and evaluated within three consecutive studies that surrounded different stages of a mission statement development, which relied on an existing e-participation platform. Our core findings show that (1) the participants of this initiative considered the use of e-participation to be helpful for mission statement creation and generally support the proposed process structure, (2) the platform’s suitability for developing mission statements was reviewed critically, making suggestions for important criteria of digital mission statement creation tools that should be met, and (3) participants could identify themselves with the final mission statement more strongly because of their own participation in the development process. While observing overall support for the suggested mission statement creation procedure, we build on the results of our studies to make suggestions for the design of e-participation platforms that will make them even more suitable for mission statement development.","PeriodicalId":41878,"journal":{"name":"IADIS-International Journal on Computer Science and Information Systems","volume":"1 1","pages":""},"PeriodicalIF":0.2,"publicationDate":"2021-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83694523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Strategy planning, i.e., the process that determines strategy, is facilitated by enterprise architecture (EA). Hence, strategic plans are reflected in EA documents called artifacts. Our research identified fifteen EA artifacts that facilitate digital transformations’ strategy planning process through a systematic literature review. Furthermore, a multiple case study in the financial services sector was carried out to verify our theoretical findings. The case organizations show a fragmented implementation of EA artifacts, with each organization having established its own, almost unique, way of using them. Only four of the theoretically conceptualized artifacts were found in all organizations. Moreover, two EA artifacts used in all case organizations were not included in our theoretical conceptualization. In combination with the empirical research, the systematic literature review leads to an improved understanding of EA artifacts and their use in the strategy planning process for digital transformations.","PeriodicalId":41878,"journal":{"name":"IADIS-International Journal on Computer Science and Information Systems","volume":"83 1","pages":""},"PeriodicalIF":0.2,"publicationDate":"2021-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83977451","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Especially since most personal and professional appliances rely on voice commands or speech in general terms to operate. These systems need to discern the identity of the speaker rather than just the words that have been said to be both smart and safe. Especially if we consider the numerous advanced methods that have been developed to generate fake speech segments. The objective of this paper is to improve upon the existing voice-based biometrics to keep up with these synthesizers. The proposed method focuses on defining a novel and more speaker adapted features by implying artificial neural networks and transfer learning. The approach uses pre-trained networks to define a mapping from two complementary acoustic features to a speaker adapted phonetic features. The complementary acoustics features are paired to provide both information about how the speech segments are perceived (type 1 feature) and produced (type 2 feature). The approach was evaluated using both a small and large closed-speaker data set. Primary results are encouraging and confirm the usefulness of such an approach to extract speaker adapted features whether for classical machine learning algorithms or advanced neural structures such as LSTM or CNN.","PeriodicalId":41878,"journal":{"name":"IADIS-International Journal on Computer Science and Information Systems","volume":"35 1","pages":""},"PeriodicalIF":0.2,"publicationDate":"2020-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86918506","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The result confirmed that students’ daily self-reflection and teachers’ feedback on them are important, and the outcome of their daily self-reflection can quantitatively show the growth in their competency. In particular, we report that the interaction between students and their teacher through the use of “Daifuku-cho” enhanced their learning and also that by comparing what the students wrote in “Daifukucho,” their grades and the results of PROG test, we suggest that the better students reflected themselves using “Daifuku-cho,” the more their competency developed.","PeriodicalId":41878,"journal":{"name":"IADIS-International Journal on Computer Science and Information Systems","volume":"62 1","pages":""},"PeriodicalIF":0.2,"publicationDate":"2020-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85111134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Brito, Paula Esteban do Valle Jardim","doi":"10.33965/ijcsis_2020150101","DOIUrl":"https://doi.org/10.33965/ijcsis_2020150101","url":null,"abstract":"This work presents a new approach to behavioral finance with a theoretical contribution by suggesting and discussing with examples a list of group behavioral biases along with established individual behavioral biases, bringing, hence, an additional outlook on how behavioral biases affect financial decisions. While individual behavioral biases are detected in individuals acting alone, group behavioral biases require the scrutiny of group behavior. This awareness may be particularly important to institutional investors, whose decisions basically stem from a committee or a group that will exhibit behavioral biases depending on how the group members interact between themselves when making a decision, which may include negotiation activities and not necessarily be related to personality or hierarchy. The focus on individual investors deciding on personal investments explain the need of work already developed in behavioral finance, which focus on individual behavioral biases, which may be a consequence from either cognitive errors or emotional biases. However, decisions from institutional investors basically stem from a committee or a group that will exhibit behavioral biases depending on how the group members interact between themselves when making a decision. To address the challenge of identifying causes and consequences for unexpected or unsuitable financial decision-making within a group, this work initially retrieves previous work on individual behavioral biases, linking emotional biases and cognitive errors to the “system 1” and “system 2” decision-making framework. Then, a conceptual contribution of this paper, which may be particularly relevant for institutional investors, is to explain with examples - after research and experience - which are the group behavioral biases and their impact upon financial decisions. Individual behavioral biases already acknowledged in other works on behavioral finance are contrasted in this work to the suggested group behavioral biases. Furthermore, this work suggests that there are two broad types of group behavioral biases: group dynamics biases and information-acceptance biases. Each broad type is subdivided into biases related to the structure of the group and biases related to how the group decision-making procedure occurs. Group dynamics biases related to the manner the group is structured are the following: kin bias (belonging bias), harmony bias, and competition bias. On the other hand, group dynamics biases may be sorted according to five different decision-making procedures, namely: herding, fad bias, Plato bias (denial bias), scarcity bias, and home bias.","PeriodicalId":41878,"journal":{"name":"IADIS-International Journal on Computer Science and Information Systems","volume":"31 1","pages":""},"PeriodicalIF":0.2,"publicationDate":"2020-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88330500","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This small study suggests that individuals are encouraged to use digital services when Government provides support, and that they are more likely to displays predictive behaviours of adoption to these digital channels. Furthermore, there are two main characteristics which predict the users choosing to shift (i.e. age and deductive benefits). Through the use of strategically placed encouragement and digital assistance, it makes an individual more likely to shift to digital channels. However, this research demonstrates predictive analytics has a stronger place in the long term adoption of eGovernment services.","PeriodicalId":41878,"journal":{"name":"IADIS-International Journal on Computer Science and Information Systems","volume":"76 1","pages":""},"PeriodicalIF":0.2,"publicationDate":"2020-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73355264","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both exercises of the same complexity were performed without and with the aid of the digital tool. Subsequently, the participants answered forms to be able to evaluate the tool, in addition to having their audiovisual products developed during the course/research been used for a blind analysis to infer qualitative gain at work due to possible time savings generated by the automation function of the tool. In the end, it was found that the DLO tool was very well evaluated conceptually and considered relevant, differentiated, with credibility and high intention of use (among other metrics).

The problem statement centers on the realization aspects of a VR assistance system for image interpretation providing a high level of immersion. This work combines the setting of a real serious game for formal image interpretation training with virtual reality to increase the immersion level. We also examined the special requirements for image quality and formal workflows that arise from professional image interpretation.

In the context of computer programming education, parents’ ignorance could affect their children’s education and attitudes towards education adversely. A promising way to support parents is through informal workshops with their children, in which the former are exposed to the subjects and skills that the children will be learning. This study examined the impact of different types of workshop activities on parents’ concerns regarding various aspects of their children’s programming education. Three types of workshops were organized, each characterized by a particular activity; including a wooden robot with coding blocks, a robotics toy with visual programming language, and visual language. Data were collected from parents before and after their participation in these workshops.
