Evaluation of the impact and fracture toughness of a nanostructured bainitic steel with low retained austenite content
Mihael Brunčko, Peter Kirbiš, Ivan Anžel, Leo Gusel, Darja Feizpour, Tomaž Irgolič, Tomaž Vuherer, 2023, original scientific article

Abstract: The impact and fracture toughness of a nanostructured, kinetically activated bainitic steel was determined using Standard methods. Prior to testing, the steel was quenched in oil and aged naturally for a period of 10 days in order to obtain a fully bainitic microstructure with a retained austenite content below 1%, resulting in a high hardness of 62HRC. The high hardness originated from the very fine microstructure of bainitic ferrite plates formed at low temperatures. It was determined that the impact toughness of the steel in the fully aged condition improved remarkably, whereas the fracture toughness was in line with expectations based on the extrapolated data available in the literature. This suggests that a very fine microstructure is most beneficial to rapid loading conditions, whereas material flaws such as coarse nitrides and non-metallic inclusions are the major limitation for obtaining a high fracture toughness.

Use of mobile technologies in tourism : natural health resorts study
Boštjan Brumen, Peter Planinc, Tomi Špindler, Mitja Gorenak, Tanja Lešnik Štuhec, 2020, original scientific article

Abstract: Mobile technologies have drastically changed the way people do everyday activities. Tasks previously reserved for desktop environments have moved to mobile devices, and nowadays, half of the internet traffic is stemming from mobile devices. The tourism industry is no exempt from the shift from desktop to mobile. In our research, we check to what extent natural health resorts have adapted and integrated mobile solutions to their websites. We collected data about the friendliness of selected websites using automated online tools and carried out a heuristic evaluation. The results were statistically analyzed and compared. Only roughly half of natural health resorts have optimized their websites for mobile devices. There are no statistically significant differences when comparing purely technical aspects. However, an in-depth heuristic evaluation has shown that some web sites are significantly more mobile-friendly than others and offer better technical conditions for enhanced user experience. Our study is the first technical and contentual evaluation of website mobile devices' friendliness in the natural health resort sector. It warns management, their marketing consultants, and web site developers about the opportunities they are missing by not supporting mobile users sufficiently. Further, it outlines deficiencies and provides suggestions and instructions for optimizing websites to enhance user-friendliness on mobile devices.

Identification of Challenges and Best Practices for Including Users with Disabilities in User-Based Testing
Boštjan Šumak, Katja Kous, Loïc Martínez-Normand, Jãnis Pekša, Maja Pušnik, 2023, original scientific article

Abstract: Despite efforts to promote digital inclusion for all, individuals with disabilities continue to experience a significant digital divide. Developing usable and accessible solutions also demands conducting user-based testing with real end users, particularly for users with disabilities, to detect and address real problems and barriers they experience and improve usability and accessibility based on their feedback through a user-centered approach. When including users with disabilities in user testing, additional attention must be paid to ensure that the testing is planned and carried out in such a way as to enable the successful and efficient integration of users with disabilities. In doing so, it is necessary to consider various restrictions related to users’ disabilities. By conducting a systematic literature review, we collected and analyzed the challenges of including users with disabilities in user-based testing and best practices that researchers can apply in future user-based testing with users with disabilities. In the existing literature, a positive trend toward publishing articles describing testing with users with disabilities is noticeable. There is also an apparent need for more reporting on some phases of the testing studies. The main result of this study is a list of challenges and best practices that are important in the different phases of user-based testing with users with disabilities.

Intelligent user interfaces and their evaluation: a systematic mapping study
Saša Brdnik, Tjaša Heričko, Boštjan Šumak, 2022, original scientific article

Abstract: Intelligent user interfaces (IUI) are driven by the goal of improvement in human–computer interaction (HCI), mainly improving user interfaces’ user experience (UX) or usability with the help of artificial intelligence. The main goal of this study is to find, assess, and synthesize existing state-of-the-art work in the field of IUI with an additional focus on the evaluation of IUI. This study analyzed 211 studies published in the field between 2012 and 2022. Studies are most frequently tied to HCI and SE domains. Definitions of IUI were observed, showing that adaptation, representation, and intelligence are key characteristics associated with IUIs, whereas adaptation, reasoning, and representation are the most commonly used verbs in their description. Evaluation of IUI is mainly conducted with experiments and questionnaires, though usability and UX are not considered together in evaluations. Most evaluations (81% of studies) reported partial or complete improvement in usability or UX. A shortage of evaluation tools, methods, and metrics, tailored for IUI, is noticed. Most often, empirical data collection methods and data sources in IUI evaluation studies are experiment, prototype development, and questionnaire.

The language of appraisal in selected TED talks : magistrsko delo
Sarah Vidmar, 2021, master's thesis

Abstract: This master’s thesis examines five selected TED Talks by using Martin and White’s Appraisal Theory (2005). TED Talks are a specific form of speech which has spread worldwide with live TED events and even videos online since the first organised TED event in 1984. The theoretical background of this master’s thesis covers mainly Martin and White’s Appraisal Theory (2005), although it does include the views of other researchers, including Mary Macken-Horarik and Anne Isaac, as well as Geoff Thompson, on appraisal analysis as well. Furthermore, it encompasses a short overview of discourse analysis and systemic functional linguistics, as this is the theoretical framework from which Appraisal Theory has evolved. The empirical part includes the analysis of appraisal in the five selected TED Talks, chosen based on the assigned tag on the official TED web page. The selected TED Talks are: “Why I'm Done Trying to Be ‘Man Enough’” by Justin Baldoni; “Dare to Refuse the Origin Myths That Claim Who You Are” by Chetan Bhatt; “How Changing Your Story Can Change Your Life” by Lori Gottlieb; “My Year of Saying Yes to Everything” by Shonda Rhimes; and “Your Brain Hallucinates Your Conscious Reality” by Anil Seth. The appraisal model explores the speaker/writer’s evaluation of certain occurrences, concepts and people in a form of his/her emotional responses, judgement and appreciation. Furthermore, it studies the speaker/writer’s positioning to alternative viewpoints and alignment with the text’s point of view. The aim of this thesis is to observe the use of appraisals in a contemporary form of a public speech, i.e. TED Talks. The further objective of this thesis is also to detect typical patterns in appraisal use within the genre of public speaking, specifically, within TED Talks which are known to have a set form and common features that distinguish them from other forms of speeches or academic lectures. Thus, this thesis aims to research ways in which the speakers of the selected TED Talks express themselves with the use of appraisals. Since all but one of the chosen five TED Talks are tagged as ‘Personal Growth’ on the official TED web page, the purpose of the research is also to see whether there are any differences in appraisal use, more specifically in the use of affect between the TED Talks tagged as ‘Personal Growth’ and the one which is not tagged as such and may therefore be more objective in its nature. Besides exploring attitudinal resources, the thesis also observes the occurrence of graduation resources and their prevalence, as well as the ways the speakers engage with their audience and their prevalence. The appraisal analysis of the selected TED Talks has proved the use of all attitudinal resources in the delivery of these talks. Furthermore, the analysis has shown that the chosen topics of TED Talks have an influence on the speakers’ use of attitudes. Affect has a prominent role in most talks, however, the more the speaker tries to stay unbiased and objective, the more she or he avoids affect in relation to her-/himself and turns to appreciation. In addition, the speakers of the selected TED Talks tend to use graduation heavily in their narrative, force being the predominant graduation resource in all selected talks. Even though the analysis of engagement resources in the selected TED Talks showed the presence of dialogically expansive expressions to be more common in four out of five examined TED Talks, dialogically contractive expressions also occur frequently in the speakers’ narratives, revealing the speakers’ attempt to balance welcoming of alternative viewpoints and at the same time maintain self-assurance in their knowledge and beliefs by restricting other voices.

Athletes friendly education handbook : Award for Educational Institutions supporting the Dual Career of Athlete
Marko Ferjan, Eva Jereb, Iztok Podbregar, Petra Robnik, Polona Šprajc, 2021

Abstract: (AFE) is a type of schooling, continually planning, organizing, and improving a system of adaptations included in a school's educational process and infrastructure. These adaptations are implemented voluntarily and in a benevolent, systematic, comprehensive, and transparent manner, with the explicit aim to help athletes engage in sport and simultaneously achieve goals and competencies set out in the educational program and thus Athlete friendly education has the following attributes: adaptations; rather than being discrete, these adaptations constitute a system; daptations are organized and managed by school management; institutions introduce the adaptations voluntarily; adaptations are based on pre-existing legal frameworks and internal institutional regulations; institutions need to possess adequate competencies or experience; they need to be "trustworthy," in other words. AFE accreditation is voluntary. The principle of voluntary certification is very similar to the "brand" philosophy. The brand also contains a "promise."

The drug market intervention approach to overt drug markets
Edmund F. McGarrell, Nicholas Corsaro, Rodney K. Brunson, 2010, original scientific article

Abstract: Purpose: The purpose of this research was to assess the impact of a strategic intervention intended to eliminate overt drug markets and their associated crime and disorder and to improve relationships between the police and local neighborhood residents. Design/Methods/Approach: The study included a process assessment of the nature of the intervention as well as an impact assessment based on trends in crime, calls-for-police-service and interviews with residents. The research occurred in the U.S. and examined a pilot program in High Point, North Carolina and subsequent implementation in Rockford, Illinois and Nashville, Tennessee. Findings: The paper presents a description of the intervention. Additionally, outcome data indicate that the intervention was related to reductions in crime and calls-forpolice service in all three communities. Raw declines were observed for violent, property and drug offenses with the declines consistently being statistically significant for drug offenses. Additionally, local residents described improved quality of neighborhood life and increased satisfaction with the police. Research limitations/implications: The results suggest that the so-called High Point Drug Market Intervention holds significant promise for addressing overt drug markets. However, the analysis is limited in that the comparison group is the citywide trend in crime as opposed to true comparison sites. Future studies utilizing quasi-experimental or experimental designs are needed to rule out potential rival explanations. Practical implications: The Drug Market Intervention appears to be a promising practice offering police officials a strategy for longer term impact on neighborhood safety and quality of life than has been the case with traditional crackdowns on drug markets. Originality/Value: This paper offers the evaluation results from three sites on a drug market intervention that has gained considerable attention, at least within the U.S.

Diskurzni okvir v predsedniški retoriki Donalda Trumpa
Žiga Krajnc, 2020, master's thesis

Abstract: This Master’s Thesis engages in research of Donald Trump’s presidential rhetoric from the perspective of evaluative framing in rhetoric. The analysis stems from Jim A. Kuypers’ theory of framing from a rhetorical perspective and J.R. Martin and P.R.R. White’s theory of language evaluation. The corpus for analysis consists of three speeches delivered by President Trump in 2017; these speeches are Inaugural Address, Remarks by President Trump on the Administration’s National Security Strategy (“America First Speech”), and Ohio Rally Speech 2017. The theoretical part consists of presenting the theory of framing as a rhetorical perspective, followed by short introduction of the theory of language evaluation. Donald Trump’s rhetoric style and characteristics are also included separately. The empirical part presents the analysis of the corpus. The research consists of two parts; the first part presents the analysis of subjects and objects and how are they framed. Furthermore, this part also detects which frames are present in the discourse. The second part consist of a discussion of results and an analysis of detected evaluative frames. It has been established that Trump’s addresses frame the President’s persona into a saviour-like figure, which offers powerful protection, security and restoration from the decay the previous administrations, supposedly, caused.
